The human fungal pathogen Candida albicans is one of the leading causative agents
of death in immunocompromised individuals. Many factors have been implicated in
virulence including filamentation inducing transcription factors, adhesins, lipases, and proteases. Many of these factors are GlycosylPhosphatidylInositol (GPI)- anchored cell surface antigenic determinant proteins. Pga1 is a short 133 amino
acid protein shown to be up regulated during cell wall regeneration. The purpose of this study is to characterize the role of Pga1 as far as filamentation on solid and liquid filamentation and non-filamentation inducing media, susceptibility to cell surface disrupting agents, oxidative stress to a potentially lethal dose of hydrogen peroxide. Furthermore, virulence in a mouse model of disseminated candidiasis, adhesion to human epithelial cells and biofilm formation will be characterized. This
will be performed by creating a homozygous pga1 null strain and comparing the
iv phenotype to the parental strain. It was observed that the null phenotype was over filamentous on both liquid and solid potato dextrose agar (PDA) media compared to the parental strain at both 300C and 370C. In addition the mutant strain showed less oxidative stress tolerance. The mutant exhibited reduced susceptibility to sodium dodecyl sulfate (SDS), but increased susceptibility to calcofluor white, both being cell surface disrupting agents. However, no differences in response to Congo red or caspofungin were observed. Furthermore the mutant exhibited a 50% reduction in adhesion and a 33% reduction in biofilm formation compared to the parental strain, which was reflected as a reduction in virulence. This data is interesting; bearing in mind that disruption of many cell surface components usually weakens the cell wall, resulting in hypersensitivity to the utilized agents and a reduction in filamentation. Whether the cell compensates a pga1 deletion and responds by up regulating other cell surface components is possible.

Candida albicans is the most common diploid fungal pathogen in humans and one of the leading causative agents of death in immunocompromised individuals. The fungus harbors an arsenal of factors that are implicated in its virulence. These virulence factors include but are not limited to filamentation inducing transcription factors, adhesins, lipases, proteases, heat shock proteins and superoxide dismutases. The cell wall in a pathogen is crucial in harboring key proteins which constitute many of the abovementioned virulence factors. Dse1 is a 724 amino acid uncharacterized cell wall protein which is involved in cell wall metabolism. The purpose of this study is to characterize the role of Dse1 by generating a dse1 homozygote null strain and comparing the phenotype of the mutant to the wild type parental strain. Characterization included extent of filamentation on solid and liquid media and adhesion to human epithelial cells and biofilm formation. Furthermore virulence was addressed in a mouse model of infection and resistance to oxidative stress and susceptibility to cell surface disrupting agents were also determined. The results of our study show that DSE1 appears to be an essential gene as we were able to generate a heterozygous but not a homozygous null strain. The heterozygous mutant showed a significant degree of haploinsufficiency as it was overfilamentous on both liquid and solid PDA media compared to the parental strain at both 300C and 370C. It also exhibited increased susceptibility to calcuflor white and SDS, both cell surface disrupting agents. However, no differences in response to two other cell surface disruptants Congo red or caspofungin was observed. In addition, the mutant strain showed a decrease in oxidative stress tolerance, exhibited a 30% reduction in biofilm formation and a delay in adhesion compared to the parental strain. These phenotypes were mirrored by a reduction in virulence in a mouse model of infection. Bearing in mind that disruption of cell surface components usually weakens the cell wall resulting in a reduction in filamentation, the hyperfilamentous phenotype of the mutant warrants further investigation.

Optimizing area and timing have long been considered to be the main design challenges in high-level synthesis. A lot of research has been conducted in this area and many techniques to improve performance have been suggested. However, as design applications become more power sensitive, and with the emergence of portable devices that operate under stringent power constraints, power consumption surfaced as a major issue to consider in the design and optimization processes.
This work studies the effects of binding and scheduling on power consumption in high-level synthesis by analyzing unnecessary switching. The major contribution of this work is to reduce the spurious switching activities in a circuit. For this purpose, all spurious and non-spurious switching inputs in a circuit were identified and many techniques were studied to find the optimal register bindings without inducing any increase in the number of storage elements. Power reduction was attained through altering register bindings using a cool-down simulated annealing approach. In order to test these techniques, a high-level synthesis environment, "Eridanus", was developed and several benchmarks consisting of various complexities have been tested. Using the approach suggested in this work, spurious switching activity was reduced by 40% on average.

Cyanobacteria known previously as blue-green algae are successful phototrophic organisms which are ubiquitously found in the environment. This organism contributes significantly to the global carbon and nitrogen budget. Classical classification of cyanobacteria is mainly based on morphology and subdivided into five categories. Molecular classification involves mainly 16S rRNA, 16S-23S rRNA intergenic spacer (IGS), and cpcBA IGS. Planktonic organisms are separated in literature based on size. We are primarily interested in picocyanobacteria (picos) as major fraction of the autotrophic picoplankton (APP) that are ubiquitously found in all aquatic ecosystems. They are major contributors of carbon and provide nutrients to their natural habitats through complex microbial food webs. Lake Superior is located in North America and has the largest surface area of any freshwater lake present in the world. The nature of this lake is ultraoligotrophic with very low concentrations of iron and phosphorous. Although 50% of Lake Superior chlorophyll is contributed by the APP, only few studies focused on studying the biodiversity of this lake. The phylogenetic diversity of Lake Superior picos was recently characterized. All samples were collected and filtered from several locations and at different depths including Sterner B (SB), Castle Danger 1 (CD1), Western Mid-lake (WM), and nearshore Keweenaw Waterway station Portage Deep (PD). Most of the 16S rRNA gene sequences clustered within the picocyanobacterial clade and two new groups pelagic Lake Superior clusters I (LSI) and II (LSII) were discovered. These groups do not cluster with any of the previously known freshwater Synechococcus. Also, these novel groups have never been isolated into culture. In our study, we assessed LSI and general picos by quantitative real-time PCR (qPCR). Specific PCR amplicons of LSI and picos were cloned into plasmid and transformed into E. coli competent cells for multiplication of the plasmid. Two separate standard curves were created for specific quantification. The concentration of general picos at CD1 (September, 2004) was found to be in the range of flow cytometry results shown by Ivanikova et al. (2007) of phycocyanin-rich and phycoerythrin-rich APP collected from the same location (August, 2006). Although Ivanikova et al. (2007) found that 16S rRNA sequences that clusters within LSI were less abundant at PD, similar and even higher concentrations of LSI were detected at this station compared to CD1, WM, and SB. WM samples collected from deep chlorophyll maximum (DCM) showed approximately the same concentrations of LSI as CD1 and PD samples collected from the epilimnion. Generally, LSI at PD and WM showed higher levels whereas picos were more concentrated at CD1 and WM. LSI proportions of picos at CD1, WM, and SB were 4.4 %, 24%, and 15.5% respectively. This study provides valuable information about the dynamics of the picos at the western arm of Lake Superior. Moreover, specific and sensitive qPCR protocol created in this study can be used in future work to monitor the spatial and temporal abundance of picos and LSI.

The increasing interest in environmental issues among the European Union public since the beginning of the nineteenth century, led to increasing pressure on European Union member countries and the European Union Institutions to develop environmental policies. This in many ways paved the way for the European Union to become a world leader in Environmental Policy making.
The thesis shows how and why the European Union became a world leader in environmental policy making. It is true that the European Union is experiencing many contradicting views on various topics such as economy and budgeting, and that is also true for environmental issues, nonetheless, the hazards of environmental problems cannot be hidden and are pressing to deal with especially as they cross national boundaries. Moreover, the huge awareness and education that the citizens of the European Union have concerning environment and its hazards plays a very important role in exerting ongoing pressure on EU member countries’ that in turn exert pressure on the EU institutions to constantly develop policies dealing with environmental issues.
The research also shows that other actors such as industries and non-governmental organizations also play a very important role during the development process as they are often consulted for technical and financial aid. NGOs also play a very vital role in lobbying for environmental policies and in supervising the implementation of the policies.
Through the research, it was also found that the European Union is able to influence other parts of the world with its environmental policy development. Such influence could be made because of the European Union’s powerful economic and diplomatic relations.
Using case studies the research also reflects how different European member countries responded to the environmental policy development and how policies were developed to fit with the European Union evolution. Also the thesis shows that though some countries such as Britain fell behind in developing environmental policies, they eventually responded to the pressure exerted by the EU.
The thesis comes to the conclusion that though the process of environmental policy making in the European Union is very complex and time consuming, the European Union’s response to public demands of various kinds regarding environmental hazards pushed it to become a world leader in environmental policy making. Moreover, the EU institutions now no longer develop environmental policies to tackle hazards when they happen, but they also work on policies to prevent environmental problems before the fact.

The objective of this study was to determine the effects of problem-based learning (PBL) on students’ performance and attitude towards chemistry. In the study, data was obtained through the use of pre-test post-test, research-control group model. The data obtained from both groups was analyzed using t-test cores, mean, and standard deviation. The study was conducted on 7th grade students, in a private school in Lebanon. Two types of instruments were used for measurement: achievement tests, and an attitude questionnaire. The research group was taught chemistry using PBL while conventional teaching methods were applied in the control group. Results indicated that implementing problem based learning approach had improved students’ achievement and attitude. This study encouraged teachers to implement problem based learning method in teaching science concepts especially chemistry for middle school students.

This is an eye opener regarding the importance of literacy, be it cultural or critical in a grade 6 classroom. It defines literacy, cultural literacy and critical literacy as well. It reveals their significance, how they are interrelated and how individuals critically learn about their culture. Moreover, the study briefly reflects on some cultural conflicts in the classroom and discusses the teacher’s, the administrator’s and the parent’s role in enhancing cultural awareness. As for the methodology, several interviews will be conducted with grade 6 teachers from different schools in Lebanon to learn more about their perspectives towards cultural literacy. The interviews focus on whether or not cultural awareness is enhanced during classroom practices, and if it is, how it is enhanced and what kind of practices, games or activities are implemented to help grade 6 students be more attentive to their cultural traditions, customs and values. The interviews will also focus on the parents' role in enhancing cultural literacy. Accordingly, a cultural awareness kit will be created. Grade 6 students will have the opportunity to learn about their culture through the novel activities, the various games and the enjoyable practices the kit contains.

This thesis is a study of one of the leading sectors in the Lebanese economy, namely its
banking sector. Actually it is an attempt to explain the strength of the Lebanese banking system in
spite of the permanent political instability in general and after the Taif agreement in particular. It
therefore analyzes the relationship between the Central Bank and the commercial banks, and the
policies and laws that allow the banking sector to prosper and the state’s actions to protect the
banking system. The liberal economic ideology prevalent in Lebanon is also central to the
explanation.
This paper analyzes how bank characteristics and the overall financial environment affect the
performance of commercial banks and their relationship with the Lebanese Central Bank.
Specifically, the purpose of the study is to give a closer look to the relationships between
profitability and the banks’ characteristics, after controlling for economic and financial structural
indicators under the conditions of the Lebanese Central Bank. A variety of Lebanese banks were
chosen, concentrating on the most profitable and the most effective banks in Lebanon. The intention
is actually to make the decision about the important determinants of performance. In this way, the
paper extends the literature in several ways (Abelson, 1983).
Politics in Lebanon has a major impact on the performance of the financial system.
However, despite this impact, the banking system in Lebanon remains active and effective. Thus,
despite the fact that the banking system in Lebanon is highly affected by politics, it remains to
maintain solidarity and effectiveness.
For this purpose, an entire set of internal characteristics is examined as determinants of
banks’ net non-interest margin and productivity. These include bank size, liquidity, loans, deposits
and some others. Also, while studying the relationship between banks’ internal characteristics and activity, I was able to detect the direct impact of external factors, such as macroeconomic inflation
and exchange rates.
It was apparent from the results and the regression and correlation analysis that the ‘Return
on Equity’ (ROE) of commercial banks is highly influenced by the independent banking variables
determined. The existing relationship is both negative and positive. While some variables affect the
profitability negatively, other variables affect it positively (Abelson, 1983).
The following empirical analysis allows me to highlight the relationship between banking
characteristics and performance measures in commercial Lebanese banks. As a start, the Lebanese
commercial banks profitability measures react positively to the increases in capital and loan ratios.
This result is in harmony with previous studies. In addition, it shows that optimal capital ratios and
loan portfolios are essential factors for determining the performance of Lebanese commercial
banks, in addition to other factors such as customers’ deposits, non-interest earning assets and
banks’ profits. Moreover, I noted that liquidity factors are even more vital for the determination of
bank performance (Abelson, 1983, p. 15).
The 1975-1990 war destroyed most of the country’s economy. However, major economic
changes accompanied the demographic changes in Lebanon and, despite this war the banking
system remained powerful in Lebanon.
Finally, it should be recognized that the range of this paper is limited as several Lebanese
commercial banks are not included and several interesting questions were left unanswered. These
questions analyze more fully the interaction between the political and the banking system in
Lebanon and show how banking stability could be influenced by the political stability of Lebanon.
Also, because of the size of the sample and many missing observations, the results should be explained carefully. As has been the case of many recent studies, the results are not very robust and
may be responsive to the type of measure of performance used. 1
Thus, in general, the profitability determinants of Lebanese commercial banks are various
and numerous in nature. The loans, size, growth, exchange rates, inflation, deposits, liquidity can
have a direct impact on the profitability level. However, the ROE level is not limited to those
variables. Other variables do have a direct impact on the profitability as well. As already noted, such variables seem to be Lebanese politics and state policies as well as other new economic and competitive regulations.

This thesis examines the cultural representation of traumatic memory. It assumes the existence of a “traumatic unsaid” that seeks expression by indirect means in art. In the case of the Irish and Lebanese cultural productions examined here, this thesis argues that artists repress painful emotions which find expression through displacement—a psychological defense mechanism in which there is an unconscious shift of emotions, affect, or desires from the original object to a more acceptable or immediate substitute—in the form of different motifs or symbols.

This study explored the perceived role of academic deans in three private universities in Lebanon. The inquiry, based on four research questions, focused on the academic deans, department chairpersons, and faculty members’ perceptions of the dean’s management leadership role. Leadership differences by gender were also emphasized. The methodology of data collection included: A review of documents, semi-structured interviews with seven academic deans, a questionnaire answered by a sample of 80 faculty members and 20 chairpersons, and a review of anecdotal accounts written by the chairs and faculty members. The researcher reviewed and analyzed the results by synthesizing and comparing the themes and responses of the three categories of participants to emphasize congruency or discrepancy of perceptions. Analysis of the findings showed that participants’ perceptions moderately agreed on their academic dean’s management leadership role. The deans’ perceptions of deanship reflected their performance of role flavored with the ideal of academic leaders expectations. The slight incongruence of perceptions did exist to a certain extent because department chairs are in a position that is closer to academic deans than faculty members and thus have more critical perceptions of the dean’s role than faculty members. Female deans were perceived more positively than male deans on faculty and program development, fiscal management, and conflict management. Male deans were perceived more positively than female deans on vision and goals, communication, and management variables. Male leadership is viewed as more directive and autocratic and female leadership as more participatory and democratic.

Mathematics educators consider proof as central to the discipline of mathematics. However, the use of Dynamic Geometry Software (DGS), which enables students to create many examples of a single figure, raises questions about the importance of deductive proof. The Lebanese curriculum does not explicitly integrate the use of DGS in geometry teaching. However, some schools are including DGS activities in geometry classes. This study aims at exploring Lebanese students’ development of geometric reasoning in problem-solving situations requiring proving, using dynamic geometry software. Participants are a conveniently accessible group of grade 8 students, at a reputable private school in Mount-Lebanon. The group consists of 35 students, 12 females and 23 males coming from middle socioeconomic background. The study involves several techniques: a semi-structured interview with the teacher, development of a math teaching unit integrating the use of Cabri-Geometer, paper-pencil problem-solving situations requiring proofs prior to unit implementation, implementation of the unit, problem solving situations in DGS context which require proving, and clinical interviews with selected groups of students while solving proof problems. The proofs produced by students using paper-pencil were compared with proofs produced in a DGS context. In addition, the mental models of geometric reasoning of students using paper-pencil were compared with the mental models in DGS context. Data collected was analyzed according to a classification framework developed for this purpose. The following results were found: students were able to produce more correct figures using DGS than when using paper-pencil. They were also able to better experiment and explore the problem. This made them understand the problem and the theorems and properties it involves. Students produced more correct conjectures. Moreover, DGS figures provided students with tools to prove so they did not give any conjecture with no proof. Though some of the proofs produced were empirical most of the proofs reflected more understanding of the concepts. Moreover, while students focused, in the paper-pencil quiz, on the format of proofs produced, they rather focused, in the DGS quiz, on the content and logic of proofs produced.

As the third wave of democratization recedes, many authoritarian regimes persist in the Middle East. These regimes have survived despite all calls for good governance, democracy and political liberalization from the international community. This thesis examines the paradox of good governance under authoritarian regimes in Tunisia and Egypt, arguing that although the last two decades did witness timid political reforms in the region, these reforms were only introduced to reassert authoritarian control.
The thesis reviews critically the literature on good governance and authoritarian persistence. It explores the main indicators used to measure good governance, focusing especially on the role of elections in examining the survival, durability and reproduction of authoritarianism in Tunisia and Egypt. These regimes have deployed elections, often assumed as a prerequisite for achieving good governance and an important stepping stone towards political pluralism, as a tool to tighten their hold on power and preserve authoritarianism.
Despite the existence of opposition parties and the holding of regular elections in both Egypt and Tunisia, political power remains firmly concentrated in the hands of Mubarak and Ben Ali and their respective parties. In these regimes, the manipulation of elections and thus the dominance of a single ruling party play an important role in sustaining authoritarian regimes and reproducing their power. The timid reform measures introduced by both regimes, have proven to be largely ineffective and have not altered Egypt's and Tunisia's political landscapes. Finally, this thesis contends that while initiatives for good governance and democracy are multiplying in the Middle East, and especially in the two explored countries, authoritarianism will survive unchallenged for years to come.

The International Criminal Court’s arrest warrant of 4 March 2009 against Omar Hassan Al Bashir made the president of Sudan the first seated president to be indicted by the ICC in history. The ICC held Al Bashir accountable for crimes against humanity, as well as war crimes committed in the Darfur region. This case study is examined to highlight how state sovereignty is changing in today’s globalized world, and to underscore the role played by international institutions in domestic politics. The thesis examines the role of the ICC in the prosecution of Al Bashir from the perspective of the realist/internationalist debate. It debates the legality of the arrest warrant given that Sudan is not a party state to the ICC and that Al Bashir is a seated president. The thesis then analyzes United Nation Security Council Resolution 1593 that transferred Darfur’s case to the ICC, UN Chapter VII, the Rome Statute, the Geneva Convention on Genocide, and the Vienna Convention to make the case against the immunity of a seated president. The responses to the ICC indictment by Sudan as well as international and regional actors, namely United States of America, Russia, China, the European Union (EU), the African Union (AU) and the League of Arab States (LAS) are also observed briefly. The thesis closes by arguing that that there can be no peace in Sudan without indicting Al Bashir. Peace and reconciliation cannot be achieved without justice.

In this project, a program based on multiple intelligences was developed for the early childhood cycle based on the theory of multiple intelligences. It is a comprehensive program to be implemented in Lebanese schools to aid preschoolers in the development of the eight kinds of intelligences according to Gardner's theory. Data were collected using interviews with teachers and experts in the field of preschool education, as well as through observations of one daycare center and three preschool classrooms. A thorough review of the literature was also conducted to identify the components of MI programs developed in preschools in the West. The MI program developed in this project includes four sections: 1) MI teaching strategies to be adopted by preschool teachers; 2) MI curricula which duplicate the Spectrum Project activities and a checklist for teachers to determine children’s intelligences; 3) A description of the MI classroom environment and of teacher-student interactions; 4) The role of parental involvement in the MI program.

The terrorist attacks of September 11, 2001, and the consequent ‘war on terror’ and the
American and British invasion and occupation of Iraq, has magnified the threat posed by Muslim
immigrant communities residing in Europe. Terrorists responsible for the 9/11 attacks were
Muslims who lived and trained in Western Europe. Moreover, and since the last quarter of the
twentieth century young European Muslims have been radicalized at a rate higher than ever
before. This study examines the impact of government policies on immigrant Muslim
communities residing in Great Britain and France. It explores whether policies of discrimination
against these Muslim communities explain recent waves of terrorist attacks in these countries.
Muslim communities living in these countries differ in terms of ethnicity and tradition; however
they are predominantly Sunni Muslims and migrants from former French and British colonies.
Moreover, although Great Britain and France are both secular democracies, each country has its
own idiosyncrasies. France is a Laic republic where religion is confined to the private sphere,
whereas Great Britain is a secular state in which the Church of England continues to play an
important political and social role. This study argues that although government policies are an
important variable to be taken into consideration, it does not have a decisive impact on the radicalization of second generation Muslims.

With the globalization of businesses and the dramatic advances in technology, institutions of higher education acting as creators of future leaders found it necessary to incorporate in their curricula and daily operations the use of new tools of instruction and management, Information and Communication Technologies (ICT). The Lebanese American University (LAU), an American university located in Beirut, Lebanon is no exception. The aim of this research work is to assess ICT uses in a private Lebanese university, in the service of academic life. The study takes into consideration faculty’s, IT administrators’ and librarians’ beliefs about, and uses of technology in their academic work. Qualitative and quantitative analysis are used in this descriptive/ assessment study. Different groups of individuals are compared and contrasted in terms of differences according to certain criteria. Questionnaires distributed to twenty faculty members in the School of Business and twenty faculty members in the School of Arts and Sciences, and interviews with four faculty, seven librarians and three IT staff at LAU are also used in gathering the data needed. The researcher hopes these results will help educators and future researchers and other entities at the university make constructive changes in their endeavors. The results show that technology is developing very fast at the university and it has many usages. Teachers use technology for course preparation, registration, research and publications and to put material on line. They also use it to communicate with students, faculty and university administration. Librarians use technology to order and to select books, to communicate with other libraries abroad and to run the work flow. The use of ICT is changing the teachers’ and librarians’ working mode to the better.

Modeling is a major aspect of science, and graphing is an abstract form of modeling that is
widely used in education. One of the teaching approaches that can be implemented in a science
classroom to improve students' graphing skills is the Inquiry-Based Modeling Approach
(IBMA). The purpose of the project was to redesign a biology unit adopting IBMA and aiming to
improve grade 1 students' graphing skills. The unit was redesigned based on Lehrer's data
display construct. This project was executed in the Lebanese context where there is inadequate
emphasis on developing graphing skills. In such a context where memorizing the content is the
major emphasis, students face many problems with graph construction and interpretation. A pilot
study was conducted on three grade 1 students to examine the feasibility of the redesigned unit.
The students were pre-tested and post-tested and the results were compared. Comparing the tests'
results showed that grade 1 students' graphing skills improved and that they were able to
appreciate the value of graphs more after the unit implementation.

The Arabic language is a difficult language to study due to the existence of two varieties
within the same language; that is, its diglossic nature. Consequently, vocabulary
acquisition in Arabic seems to suffer because both varieties known as standard Arabic
and colloquial Arabic are acquired in different ways and are linguistically distant. Only a
few vocabulary words are shared by both varieties while all the other vocabulary words
of standard Arabic need to be taught in school. Hence, the distance between the two
varieties of Arabic affects vocabulary acquisition of the language. No formal studies exist
on the relationship between diglossia and vocabulary acquisition. This study includes two
objectives. The first objective of this study is to investigate the effect of diglossia on
vocabulary acquisition of bilingual Lebanese students in Arabic. The second objective is
to determine which vocabulary (Arabic vs. English) students have a preference for.
Students' picture vocabulary acquisition was tested in Arabic and English. A correlation
design based on a two stage random sample was used. The participants (n = 100)
answered orally and in writing, depending on their age level, a subset of the Woodcock
Johnson-III Tests of Achievement (Picture Vocabulary). On a second task, they identified
orally and in writing, depending on their age level, the names of the different body parts
by looking at a drawing of a human figure. The results showed a significant relationship
between diglossia and vocabulary acquisition in Lebanese bilingual students. The
students showed more confidence in using the English language over Arabic. These
findings suggest that teachers need to use different research-based vocabulary strategies
to try to tailor to the students' needs and to try to overcome the diglossia challenge
related to the Arabic language.

Organizational Climates are the set of expectations that represents a property of organizational environments that is perceived directly or indirectly by individuals in that organization. The main organizational climates that have been identified are: Structure, Responsibility, Risk, Reward, Warmth and Support, Conflict, Expect Approval. Considerable research indicates the Organizational Climates are related and affected by certain organizational environment. The learning organization is the set of dimensions that continuously change and adopt the learning concept in an organizational environment maintaining a competitive edge. The learning organization dimensions include: Continuous Learning, Dialogue and Inquiry, Team Learning, Embedded Systems, Empowerment, System Connections, and Provide Leadership. In this study, our purpose is to examine the effects of the learning organization dimensions on organizational climate. Data gathered through questionnaires distributed to employees from various industries in Lebanon are analysed. Using various statistical techniques, the dimensions that affect each organizational climate are identified and the strengths of the relationships are determined. Several hypotheses regarding the learning organization dimensions

After a period of prosperity that the MBA degree has realized, the 90s
seem to be a decade that threatens the essence of such degree. The notion that
an MBA is crucial for the operation of any company is beginning to fade
away.
This research gIves clear information, from both the academic and
business sectors, about the MBA degree and its usefulness to the Lebanese
market.
The universities are producing a fine quality of MBAs who proved to
be knowledgeable and efficient at work. Moreover, they proved to be at the
same standard, and in some cases better than, those graduating from abroad.
However, some companies are not encouraging these students. They offer
them the same salary and position as any other employee who does not have
an MBA degree.
A link must be made between the academic sector and the busines
sector through which the universities can provide the companies with
employees who can operate according to their needs.

This project presents a new approach to Quasi-Newton methods for
unconstrained optimization. Quasi-Newton Methods update at each iteration the
existing Hessian approximation (or its inverse) cheaply by integrating data derived
from the previously completed one, which is soon ignored. These methods are based
on the so-called Secant equation. In our project we focus on solving a critical
subproblem of the Quasi-Newton algorithm that requires determining a proper,
suitable step size that takes from the current approximation to the minimum to a new
'better' one. The subproblem can either be posed as doing a Line Search along some
generated search direction in order to determine a minimum along the search vector.
Another technique, on which we focus primarily in this work, is to use a Trust Region
method that directly computes the step vector without doing a focused Line Search.
The subproblem is critical to the numerical success of Q-N methods. We emphasize
features of successful implementation to pinpoint assess merits of Trust Region
methods. Our Numerical Results reveal that Trust Region algorithms seem to
markedly improve as the dimension of the problem increases, while for small dimensional problems performance of both methods is comparable.

The segmentation and recognition of Arabic handwritten text has been an area of
great interest in the past few years. However, a small number of research papers and
reports have been published in this area. There are several major problems with Arabic
handwritten text processing: Arabic is written cursively and many external objects are
used such as dots, 'HanlZa', 'Madda', and diacritic objects. In addition, Arabic characters
have more than one shape according to their position inside a word. More than one
character can also share the same horizontal space, creating vertically overlapping
connected or disconnected blocks of characters. This makes the problem of segmentation
of Arabic text into characters, and their classification even more difficult. In this work a technique is presented that segments difficult handwritten Arabic
text. A conventional algorithm is used for the initial segmentation of the text into
connected blocks of characters. The algorithm then generates pre-segmentation points for
these blocks. A neural network is subsequently used to verify the accuracy of these
segmentation points. Another conventional algorithm uses the verified segmentation
points and segments the connected blocks of characters. These characters can then be used
as input to another neural network for classification. Two major problems were encountered in the above scenario. First, the
segmentation phase proved to be successful in vertical segmentation of connected blocks
of characters. However, it couldn't segment characters that were overlapping horizontally,
and this affects any neural network classifier.
Second, there are a lot of handwritten characters that can be segmented and
classified into two or more different classes depending on whether you look at them
separately, or in a word, or even in a sentence. In other words, character segmentation and
classification, especially handwritten Arabic characters, depends largely on contextual
information, and not only on topographic features extracted from these characters.

Stress is an integral part of everyone's life.
Stress at work is receiving increased attention in all organizations. Most
managers understand stress intuitively. It is usually an emotional discomfort
accompanied by feelings of not being able to cope, that one is not in control, or it
may be an unease that all is not well. At the physical level, it includes loss of
appetite, sleeplessness, ulcers ...
On individual level, as a consequence of stress, the body's system is
thrown out of balance. Excess acid is secreted in the stomach. Adrenaline
appears in the blood and heart rates increase. Stress, then, is a
psychophysiological phenomenon. Intense feelings and emotions are often the
result of experiences we encounter within organizations. Some experiences are
more stressful than others, and the same type of experience can be more stressful
to one person than to another. Thus the stress potential of a situation can be
defmed as a function of two elements: the situation and the individuals.
Stress at work results from time pressures, work over/underload, conflict,
lack of information, role ambiguity, change, priorities in work when they are not
defined and many other causes.
Organizationally, stress can produce declines in productivity, in
motivation, in work quality, in alertness and effectiveness; and increases in
mistakes, in interpersonal conflicts and turnover. Stress has proven to be a major
cause for low job performance levels.
The first step to combating stress is awareness. The individual should be
aware of stress susceptibility in a variety of situations. With an understanding of
the sources of his discomfort, the individual may examine his behavior for signs of the effects of stress (i.e. understand the causes and symptoms of stress, when
they have a controlling role in their stress levels, they become able to work with
that stress). There is no one made-to-order method to manage stress. If one
knows that a situation will be stressful, it would be best to avoid it if possible. If
the stressors must be faced, then the best way to cope is to be prepared mentally
and then to take effective action. Possible coping efforts include exercising,
learning to relax, developing non-work interests, fmding social support, doing
something nice for oneself and for others, or developing a positive attitude. One
should try to see the bright side of things and to convert anger to joy. If a person
fmds that he cannot handle it alone, then he should seek personal or professional
help.
Although eliminating the causes of workplace stress is impossible,
managers can take action to reduce stress, to manage it. Only the managers who
know how to shape their behavior adroitly to fit the organizational demands
which create stress can flourish and be effective.
Several management strategies to prevent and reduce stressors in the
work place are available: Carefully planned change processes, role clarification,
performance standards, supportive enviromnent, training programs, promotion
policies, time management, open communication channels, decentralization in
decision making, development of cohesive work groups etc.
Defining, identifying, understanding, adapting and accepting are key
words in stress managementl. Do what you can, the best that you can and accept
the consequences. This is all that you should expect from yourself in coping with
stress.

Proteins are organic compounds made up of chains of amino acids. Chemical and
physical properties determine the 3-dimensional structure and folding of a protein. A
protein needs to be folded into its proper 3D structure for its function to remain intact.
The protein structure prediction problem has real-world implication, since the 3D
structure of a protein gives important clues regarding its function, localization, and
interactions. Wet laboratory techniques are costly in terms of time and effort,
consequently having a right protein structure prediction model reduces cost and time
by eliminating some of the initial wet lab work. Consequently, we need to study
methods that predict protein structures. In this thesis, we present an improved scatter
search (SS) algorithm for predicting all-atoms protein structures using the
CHARMM22 energy model. Our algorithm produces a 3D structure of the whole
protein by minimizing the energy function linked to protein folding. This is based on
a sequence of amino acids as well as on data collected from known protein structures
for comparative purposes. Defined as an evolutionary algorithm, SS relies on a
population of candidate solutions. Candidate solutions, over a number of iterations,
experience evolutionary operations which combine intense search and diversification.
Our algorithm is evaluated on few proteins, whose structure is defined in a Protein
Data Bank (PDB). The results generated by the improved SS algorithm are compared
with those of other energy models. Our results showed that our algorithm produces
3D structures with good and promising root mean square deviations from the
reference proteins. This study also demonstrates the advantage of the CHARMM22
energy model.

We present a comparative study of popular regressIOn testing algorithms. These
algorithms include slicing, incremental, firewall, genetic, and simulated annealing
algorithms. The study uses a variety of small-size and medium-size modules along with
associated test cases tables, and is based on the following quantitative and qualitative
criteria, efficiency, number of retests, precision, inclusiveness, user's parameter setting,
global variables, type of maintenance, type of testing, level of testing, and type of
approach. The comparison results show that the five algorithms are suitable for different
requirements of regression testing. Slicing and adapted firewall algorithms detect the
definition-use pairs that are affected by a change, and select the test cases for regression
testing based on these definition-use pairs. Incremental algorithm selects the test cases
whose outputs may be affected. Genetic and simulated annealing select the minimum
number of test cases that provide full testing coverage. In terms of execution time for
small-size modules, slicing, incremental, and adapted firewall algorithms exhibit a better
behavior comparing to genetic and simulated annealing algorithms. For medium-size
modules, the adapted firewall algorithm becomes the slowest. Genetic and simulated
annealing algorithms produce the least number of retests, followed by incremental,
slicing, and then adapted firewall.

This work introduces a new approach to record clustering where a hybrid algorithm is
presented that clusters records based upon threshold values and the query patterns
made to a particular database. We study the space density of a file and how it affects
retrieval time before and after clustering. The hamming distaoce of a file is used as a
measure of space density. The objective of the algorithm is to minimize the hamming
distance of the file while attaching significance to the most frequent queries being
asked. Simulation experiments conducted proved that a great reduction in response
time is yielded after the restructuring of a file. Criteria, such as, block size, threshold
value, percentage of records satisfYing a given set of queries, etc ... , which affect
clustering and response time are also studied. Random statistical and graph theory are
used to substantiate the experimental results. As a further means for predicting
perfonnance, regression analysis is employed and later compared to experimental
figure.

At the present moment, the General Directorate of Railroad and Public Transportation IS III a very serious situation because
neither the motor vehicles nor the railroads are earning sufficient
revenues to cover their reasonable expenses. The causes are
numerous but whatever these causes are, the effects will still be more
destructive if no serious measures are to be taken.
Policy decision bearing on anyone transportation mode III
Lebanon will have repercussions on the others because public
transportation IS not a function by itself, it does not operate in entire
independence to which standards can be applied without reference to
their effects upon other parts of the social body.
This thesis will try to analyze the General Directorate of
Railroad and Public Transportation's policy game and the reasons
behind the deterioration of public transportation system in Lebanon .
. '
The purpose is to assess the future of public transportation 111
Lebanon, an administrative assessment in view of current practices.
The main points which are thoroughly investigated in this research
are administrative options available for the General Directorate of
Rail Road and Public Transportation, manpower, bus operation,
financial position and performance indicators that could help decision
makers at the strategic level to better predict the future of public
transportation in Lebanon.

The advancement in computer technology over the last forty years has affected many
aspects of education. This advancement has prompted educators to gradually attempt
integrating this technology into their classroom practices by using computer assisted
language learning (CALL) programs. Moreover, this integration has further prompted
educators to find a theoretical framework to govern their integration of information
technology or IT. This paper attempts to study the extent to which CALL applications
could affect students’ higher order thinking skills. It also examines the effectiveness of
a WebQuest on learners’ critical thinking abilities and the practices teachers adopt to
foster these abilities.The study is conducted through a mixed method causalcomparative
design using purposive sampling of 48 students in three different classes.
Results indicate that students who use CALL showed higher order skills such as critical
thinking and problem solving in acquiring the target language than those who do not.
However, the results also indicated that knowledge of use of computer key board skills
and use of software and the internet could hinder learning if not dealt with efficiently.
Implications for classroom teaching/learning and recommendations for future research
are made.

The Lebanese Electric Power System (LEPS) suffers from technical and financial deficiencies that required the development of a policy paper to rescue the power sector from the current drastic situation to a new sustainable, reliable, and efficient delivery of electricity. The plan includes ten strategic initiatives and 42 action steps that are integrated and correlated to cover the sector’s infrastructure, supply/demand, and the legal aspects. This ambitious but realistic policy was prepared after a review of all previous studies, and in collaboration of all concerned parties, whether internal or external, constitutional and political, and was approved consensually by the Council Of Ministers on June 21, 2010.
It is proposed that the implementation of the energy policy will result in a solid power sector with sufficient generation capacity, reliable transmission and distribution networks, and efficient delivery of electricity to cope with the overall socio-economic development of Lebanon. The policy targets a gradual implementation of the initiatives in the short and medium terms totaling 4870 M$ (Government in Lebanon up to 1550 M$, the private sector contribution of 2320 M$, and the international donor community up to 1000 M$), and an additional amount of 1650 M$ in the long term. The full implementation of all the strategic initiatives in this policy will reduce the total losses from 4.4 Billion $ in 2010 to zero in 2014 where 24/24 hours of service is provided, and the possibility of profit making as of 2015; while it will reach 9.5 Billion $ in 2015 if no action is taken.
This thesis uses the Load Modification Technique (LMT) as a stochastic tool to assess the impact of implementing the initiatives of the proposed energy policy on energy production, overall cost, technical and commercial losses, reliability and customer service. New modeling capabilities of the traditional LMT method are proposed in this thesis for off-peak energy dispatch. The proposed LMT technique is used to establish a technical and financial baseline of the LEPS against which the full implementation of the energy policy is compared and the resulting tariff is calculated. Selected scenarios are also presented to show the technical and financial impact of individual projects on the system.

Ghrelin is a 28-amino acid octanoylated peptide that has been isolated from rat stomach and stimulates pituitary growth hormone secretion. Growth hormone (GH) is a potent endocrine modulator of growth and metabolism. Genotropin is a recombinant human growth hormone (rhGH) that increases lean body mass, skeletal muscle mass, muscle force and strength, aerobic performance, and fat loss. A very important issue regarding ghrelin physiology is whether an axis or loop exists between pituitary GH on one hand and plasma, stomach, pancreas and kidney ghrelin on the other hand thus reflecting how GH elevations or reductions directly affect ghrelin homeostasis and secretion. The purpose of this experiment was to study the effects of a 5 day treatment of genotropin subcutaneous injection (2, 20, and 100 μg/rat/day) on active ghrelin concentration in rat plasma, stomach, kidney, and pancreas samples.. The Active Ghrelin ELISA kit results showed a significant increase in active ghrelin concentration in the rat plasma samples and a significant decrease in active ghrelin concentration in the rat stomach, kidney, and pancreas supernatants. Moreover, protein results using Lowry assay for protein determination showed that genotropin injection led to an increase in protein concentration in stomach and kidney samples and to a drastic decrease in protein concentration in the pancreas samples. Calculations revealed that genotropin injection decreased active ghrelin concentration per μg of protein in stomach and kidney supernatant but had no significant effect on active ghrelin concentration per μg of protein in pancreas supernatant. In conclusion, these findings show that GH lowers active ghrelin concentration in the stomach, kidney, and pancreas samples thus suggesting a feedback loop between stomach, kidney and pancreas ghrelin on one hand, and pituitary GH on the other hand.

Local Area Networks (LAN’s) are being expanded over large geographic areas and
they are used in many business fields. Thus, communication links between buildings
are to be optimized in order to achieve high transmission rates, high performance
levels, low cost and ease of deployment. Free-Space Optics (FSO) is a communication
system that achieves all of the above objectives and, thus, constitutes a strong
candidate solution for such networks.
FSO systems are based on transmitting information through light beams in free atmosphere
and they suffer from fading due to atmospheric scintillations. Fading effects can
be reduced by deploying laser arrays and photo-detector arrays at the transmitter and
receiver sides respectively. Such systems are referred to as Multiple-Input-Multiple-
Output (MIMO) FSO systems. In addition to their robustness against fading, MIMO
FSO systems can also enhance the data rate since the array of lasers can be driven
by independent information sources.
Fading over FSO channels is often modeled by either Log-Normal or Rayleigh distributions.
In this context, the first contribution of this work consists of an analytical
characterization of the diversity order that can be achieved by MIMO FSO systems
over such channels. Based on the Erlang approximation, closed-form expressions of
the error-rate and channel-capacity were derived. These simple expressions offer useful
insights on the performance gains that can be achieved at a given Signal-to-Noise
Ratio (SNR).
On the other hand, for estimating the values of the transmitted signals, exiting MIMO
FSO systems are often associated with Maximum-Likelihood (ML) decoders. Although
these decoders achieve the smallest error rate, they suffer from an increased
complexity since the required decoding time increases exponentially with the size
of the transmitted constellation. The second contribution of this work consists of
proposing two novel simplified ML decoders that reduce the processing time without
increasing the error rate. We also propose suboptimal versions of these decoders
that present the advantage of very fast convergence times at the expense of a slight increase in the error rate. All the presented analysis and designs are supported by
simulations and analytical proofs.

With the frequent occurrence of fiber cuts in optical core networks and the tremendous loss that a failure may cause, the design of survivable optical networks is becoming of extreme importance to optical network operators. One of the major concerns in this regard is related to improving the availability of the services that the optical operators offer to their clients. This work addresses this issue by presenting three novel availability-aware protection schemes that achieve high level of availability for optical connections. As a distinguishing feature from existing protection schemes, the proposed schemes introduce relative priorities among the different primary connections contending for the use of the backup resources. In an attempt to gauge the benefit of the proposed protection schemes relative to the ones studied in the open literature, mathematical models are provided for evaluating the average connection availability resulting from the deployment of such schemes. The numerical results obtained from the mathematical models prove that higher availability levels can be realized through the use of the availability-aware protection schemes defined in this work.

Network-on-Chip (NoC) is a new technology that embeds heterogeneous intercon-
nected cores. NoC's design is based on a selected network topology, a switching tech-
nique and a routing strategy in order to allow on chip communication. Its advantages
over System-on-Chip (SoC) are that NoC provides modularity, higher performance,
better structure, and compatibility with core designs and reuse. Trades-o exist be-
tween them.
In this thesis, we tackle the NoC core testing time problem. We use a grid topology,
a variable Test Access Mechanism (TAM), a computed optimal
it size based on the
bandwidth and bu er size, the standard test wrapper, and XY routing strategy. Our
goal is to test all cores, under the above constraints, while minimizing overall NoC test
time. For this purpose, we have partitioned the cores into sets using two partitioning
techniques. The rst is based on grouping together all cores that have similar or close
core testing time, and the second is partitioned based on the lower bound computed
for each benchmark. In order to evaluate our work, we present experimental results
that are compared to each other.

The success of any organization depends largely on 'those called to carry out its
operations and to achieve its goals ,employees. Employees are then the most
valuable assets in any organization ,especially in labor intensive and service
businesses such as Banks. Therefore, acquiring. this new "Human Asset "
should receive the same im'portance or even more importance than acquiring a
new fixed asset.
The main purpose of this reseitrch is to assess the adequacy of recruiting and
selection processes followed by banks operating in Lebanon. In addition, this
research aims at studying the impact of recruiting an selection on employee
satisfaction and turnover.
Based on the results obtained, it was found that the recruiting process is
adequate but it needs some improvements . while it was found that the
selection process in most of the banks contacted is below standard. It was also
found that employee satisfaction and turnover are dependent on the adequacy
of placement and recruiting policies.
Therefore, to secure the placement of the right person in the right place, to
increase employee satisfaction, and to reduce employee turnover among new
hires, it is recommended that the personnel managers should be personnel
oriented, they should always update their knowledge through seminars and
readings in personnel materials, they should assess the effectiveness of their
recruiting and selection processes continuously to correct any mistakes in them,
they should treat all recruits at all positions equally. Finally, they are
recommended to try the use of recruitment software applications that facilitate
their work and save a lot oftheir time.

Today with each successive generation people can expect
several periods of change and they must cope with them at a faster
rate of imposition. The pace of change is accelerating. Under these
conditions, the knowledge and skills gained yesterday will no longer
be sufficient to equip a person for a lifetime. They are only
appropriate for a short period of time before becoming obsolete.
They must therefore develop a new training system. They
should be moving away from the traditional method of transmitting
knowledge and, instead should be helping people to learn. Adopting
multimedia training method is an effective tool to train people and
make them understand and learn quickly.
In this research the importance of computer-assisted training
are presented and the various kinds of training are listed. As a
powerful and effective training tool, multimedia technology has a
great part of this research. The meaning of multimedia as well as its
elements and applications are also presented and defined to highlight
its importance and ability in providing information and enrIching
knowledge.
To show the effectiveness of adopting multimedia technology in
training, an experiment was applied on two groups of subjects. Each
group was asked to answer questionnaires, solve different problems,
then they were asked to answer two different kinds of evaluation
forms. After this experiment some statistical models were applied on
the collected data to end up with a conclusion stating that
multimedia is a new and powerful tool to teach and train people.

Final Exam Scheduling is a real and troublesome problem that all institutions of higher
education are fuced with a few times a year. This report presents the implementation of
a Final Exam Scheduling Package (FESP) at the LEBANESE AMERICAN UNIVERSITY. FESP
distributes the final exams among the exam sessions and assigns exams to classrooms.
It takes into consideration student conflicts and accommodates splitting of exams
among classrooms and sharing classrooms among exams. We present the package
specification, the approach, the algorithms, the design, and the implementation
techniques (using ORACLE R-DBMS and Tools). The experimental results obtained on
real-life data show that FESP yields a substantial decrease in the number of exam
conflicts in comparison with those obtained by the manually prepared exam schedule.

The research at hand describes and assesses the marketing topics and functions
that concern the marketing performance of Columbus s.a.r.l., the exclusive agent of
Johnson and Johnson; Gillette, Uniliver, and Bristol Myers Squibb products in
Lebanon. Columbus along with twelve other decentralized companies form Fattal
Holding s . .a.l. which is specialized in the distribution and marketing of nationally and.
internationally branded products.
Columbus' marketing environment is shaped by many factors and actors. The
demographic environment, for instance, has witnessed drastic changes such as the
trend towards urbanization causing a reshuffling of the target market members. The
economic environment has been affected by megatrends in the past decade (1984-
1994) leading Columbus to adjust its pricing policies to the galloping inflation (1984-
1992). Consequently, the dollarization policy for its products was introduced. This
situation has also led to advantages such as the sharp decline in wage rates. With
respect to the political situation, it has affected Columbus due to the military disorder
and fragmentation of the national territories in the war era. Columbus took certain
measures some of which are still applicable such as decentralization in distribution.
With respect to the controllable factors in Columbus' marketing environment,
they mainly are the suppliers, marketing intermediaries, customers, and competitors.
The suppliers are multinational firms who manufacture highly reputed products and are
accredited for their global distribution and excessive worldwide promotions and
advertisements. They provide Columbus with advertising and promotion budgets and
suggested marketing plans for the individual products. With respect to the marketing
intermediaries, they include five subagents which distribute Columbus'_products in the
different Lebanese regions (excluding East Beirut) , retailers, four advertising agencies
for Gillette, Bristol Myers Squibb, Uniliver, and Johnson and Johnson units, and
insurance and financial services companies. In addition, Columbus customers include
the consumer, institutional, and reseller markets- each with distinctive characteristics.
Finally, Columbus' competitors are several; some of its products have strong rival
brands while others such as J&J baby care products have few ones.
However, the core marketing activities and functions are the ones which
determine Columbus health situation . Columbus pursues four major objectives :
increase profitability, keeping up the good reputation, creating innovation, and most
important market share improvement . The marketing objectives stem from the latter objective and primarily include increasing sales of existing lines, adding new products,
and expanding the number of retail outlets.
The marketing strategies come in conformity with the stated objectives.
Columbus possesses competitive differentiation for its marketing offers; its employed
tools in this respect are product, image, and personnel differentiation. The marketing
strategies focus on expanding Columbus' market share .With the major aid from its
suppliers, Columbus is performing a satisfactory job in implementing and monitoring
the annual marketing plans . The market share figures which are high for most of
Columbus' products prove that.
The marketing mix elements are well managed and integrated with the
suppliers' marketing goals . That is, the breadth, length, and depth of Columbus'
product mix are well suited to both parties, Columbus and the supplying corporations.
Regarding distribution, full market coverage is employed either by Columbus or its five
subagents. With respect to pricing, it is not a matter always within Columbus' control.
These is some kind of regional pricing excerted by the suppliers for the sake of
preventing smuggling of goods from one regional country to another. Promotion, in
the case of Columbus, is a field in which it has an advantage for several reasons
among which are the professional promotion management of its suppliers and the
huge budgets for the promotional activities which primarily come from the suppliers
abroad.
In summary, Columbus fulfilled its objectives in 1993. Sales growth was
achieved and profits were increased to the extent that it was number one in Fattal
Holding s.a.!. in 1993 based on productivity, profitability, and return on investment.
Return on investment (measured in terms of 1993 net profits as a percentage of
Columbus' capital) increased through increasing sales and market shares and cutting
back costs via centralizing the overhead expenses and reducing the variable costs.
In the end, it would hardly be appropriate to describe Columbus as an
organization that has fully implemented the marketing concept. In the researcher's
OpInIOn, Columbus is thought to lie somewhere between the selling and the marketing
concept . Reaching a status closer to the latter should be aspired for blunders like high
profit margins and no-sales commission policy contribute to drawing it closer and
closer to the selling concept rather than to the other, more developed. one.

This report describes a software maintenance tool that reduces the maintenance effort and
cost. Its goals are: to provide consistent documentation of a software system during both
its development and maintenance phases; to help maintainers understand the architecture
and algorithm of a software system without having to go over the actual code or paper
documents; to identify any interrelationship between the various parts of a software
system so that maintainers can better determine the affected and involved parts in a
maintenance change; to provide a disciplined procedure to implement any maintenance
action.
An important feature of this tool is dealing with the version control problem which is
needed in any baseline, where multiple versions of the same software and its parts are
present, facilitating the identification of each configuration of a software system and its
constituent parts at anyone time.

The purpose of this research is to find if there is a
difference between external and internal auditors, and
if they are properly performing their duties in Lebanon.
The paper IS organised as follows:
Chapter 1 defines auditing, its types, and the
structure of each type. It presents the historical
background of auditing. It also gives an idea about the
certificates that auditors may hold and the associations
they belong to.
Chapter 11 describes the responsibilities,
objectives, and functions of both external and internal
auditors.
Chapter 111 deals with the different phases of
performing an audit task that includes planning, scope
of work, performance of work, communicating results,
follow up, and evaluation of work. It also explains the
relationship between external and internal auditors.
Chapter IV highlights the methodology used in
conducting the research.
Chapter V presents the results of the questionnaires
and of the interviews.
Chapter VI states the conclusion and offers
recommendations that might help overcoming the
problems identified in the previous chapter.

The debate of whether to teach or not to teach grammar has been of great significance in
the language field. Nowadays, the teaching of grammar is being re-evaluated. Many
researchers believe that grammar in itself is essential; it is the way it was treated that
made it dull and ineffective. Therefore, the focus of this project is to find effective and
motivating ways in which grammar can be introduced to students. The intent of this paper
is to help teachers present grammar in a motivating way. Thus, this project provides
teachers with a teaching kit that has a number of interesting and fun techniques to help
students notice grammatical structures and apply them while communicating with each
other in a relaxed environment. Teachers can adjust the proposed techniques according to
the needs of their students. The provided kit is a guideline for teachers who are willing to
innovate in the classroom and allow for continuous interaction between students.

The purpose of the present study was to examine differences in leadership styles
between men and women school principals in Lebanon. In other words, thi s study
explored gender differences among school principals. The sample of thi s study
consisted of two principals and twelve teachers belonging to two schools in Lebanon.
The instruments used were interviews and observation sessions developed accord ing
to the western literature. The results reveal ed that women school principals lead in a
more open, efficient and democratic way than men school principals do. The male
school principal in this study was authoritarian, used one way communication
patterns, took decisions unilaterally, didn't empower the teachers and handled
conflicts in a one-sided approach. On the other hand, the female school principal in
this study was democratic, used direct interpersonal contacts, decided collaboratively,
empowered her teachers and consequently trusted them and resolved confl icts justly.
Similarly, the teachers under the male school principal perceived him as authoritarian
and the teachers under the female school principal described her as democrati c.
Additionally, the observation reports suppOlted the results and reveal ed the existence
of two different leadership styles in the two schools.

Professional Development is related to in-service training of teachers in workshops, and
to collaborative work within professional communi tics in which teachers reflect on their
practices and exchange ideas and activities. Teacher's self-efficacy is related to thc teacher's
confidcnce in hislher ability to exhibit innovative strategies, motivate students and produce
change in their outcomes. A study was conducted in a private non-profit school located in
Beirut to examine the influence of professional development on teacher's self-efficacy.
Qucstionnaires, interviews and observations were conducted to triangulate data results.
Participants included fourteen teachers, whereas interviews were conducted with three
coordinators who were chosen purposefully. It was found that professional development has
positive influence on teachers' self- efficacy. Future researchers could conduct this study on a
laiger sample of schools or they can change it into a longitudinal research with statistical
measures to obtain more reliable results.

The purpose of this study is to investigate the following areas of induction programs:
components, effects, principals' roles, and mentors' roles. The target school, located
in the suburbs of Beirut, Lebanon, has 759 students and 112 staff members, most of
whom come from the middle socio-economic status. Data were collected through the
use of questionnaires and semi-structured interviews. Frequency counts were used
for the analysis of questionnaires and interviews were transcribed, categorized, and
analyzed. The results of both interviews and questionnaires were compared and found
in harmony. Results showed that teachers have good relations with their directors.
However, providing teachers with a handbook may serve useful in learning the
school's rules and regulations. Also, results show that earlier hiring and recruiting
may help in preparing teachers for their teaching profession. The results were found
to be in harmony with those in the reviewed literature.

This study was conducted on II department heads at Universite Saint-Joseph (USJ) to
examine whether emotional intelligence is a qua lity of leadership at institutions of higher
education in Lebanon. Participants were selected according to non-probability sampling
based on the researcher's judgment The participants answered the EQ-i: S questionnaire. The
scores were evaluated according to scales following the guidelines of the EQ-i: S manual.
Results showed that emotional intelligence is a qua lity of leadership at USJ. Department
heads received average to high scores in Total EQ except for one male leader. Females scored
slightly higher than males on Total EQ. Moreover, female academic leaders showed better
stress management scores than male academic leaders. Age and gender differences were not
apparent in the other scales.

In this work, we investigate the cooperative diversity technique as a candidate
solution for combating turbulence-induced fading over Free-Space Optical (FSO) links.
In particular, a one-relay cooperative diversity scheme is proposed and analyzed for noncoherent
FSO communications with intensity modulation and direct detection (IM/DD).
The error performance of this diversity scheme is derived in semi-analytical and closedform
expressions in the presence and absence of background radiation, respectively.
Results show the enhanced diversity orders that can be achieved over both Rayleigh and
lognormal fading models.

The stock exchange is an essential component of any developed financial system.
Its financial intermediation role stems from its ability to channel investment and other
sorts of funds to their most efficient uses. While size, structure, liquidity and efficiency
are essential factors for a stock exchange to prosper, market perception can have its impact in making or breaking that particular stock market. The way the market values shares trading on a stock exchange can either build or destroy value. If shares are
perceived as 'overpriced' in terms of PIE or PIB for example, by investors, demand will wither and the market will go down. On the other hand, if shares are perceived as
'under-priced', the market could boom very quickly. A stock exchange that is able to develop an efficient pricing system where, overall, market prices reflect fundamental
values of companies, will be able to grow and to position itself among the world's
leading stock markets.
This study attempts a market valuation of Lebanese stocks, particularly banking
shares, in terms of price multiples such as PIE, PIB and PI A coupled with a regional
comparative analysis. The results obtained indicate that the Lebanese banking sector, with a PIE ratio of 15.24x, is in line with PIE ratios recorded in the Middle East and
North Africa region. On the other hand, the Lebanese banking sector has a slightly higher
PIB ratio of3.20x, when compared to regional peers. On an individual basis, Lebanese
banks had varying price multiples depending on the specific features of each bank. While
the prospects of the stock market as a whole are rather strong, major challenges relating
to political and country risk persist and will have a direct impact on the development of
an embryonic stock exchange.

We analyze the sensitivity to parameters and the general applicability of genetic algorithms and simulated annealing algorithms for mapping data to distributed-memory
multicomputers, using the loosely synchronous computation model. The analysis includes sensitivity to user parameters, fault tolerance capability, and applicability to
different multicomputer topologies. The user parameters are either objective function dependent or algorithm dependent. The fault tolerance capability is demonstrated by
using the mapping algorithms for mapping data to a multicomputer that has some failed processors. We assume a hypercube multicomputer architecture in most
experiments. However, comparative results for mesh, array, ring, tree, star graph, and
fully connected topologies are presented. The mapping algorithms used are sequential
hybrid genetic algorithm, versions of a distributed genetic algorithm, sequential simulated annealing algorithm, and a simulated parallel simulated annealing algorithm. The experimental results verifY that these algorithms are insensitive to user parameters
in wide ranges, completely fault tolerant, and unbiased towards particular
multicomputer topologies. These results support the conjecture that physical optimization algorithms are flexible and have general applicability, where these properties are necessary for the automation of the mapping process.

The system presented herein aims at putting together a decision support tool that
functions on a GIS platform. The project has been specifically tailored for Makassed which is a philanthropic association, with many institutions that have been founded in order to provide services to the Moslem groups in Lebanon. Makassed needs a tool that could be used as a reference in order to allow people to have a general idea
about its institutions and about what they offer. The best method found to achieve this objective is to use Geographic Information Systems (GIS), because a GIS can handle spatial data in addition, to aspatial data. So by using GIS we will be able to
relate the locations of these institutions (spatial data) to any data that describe them
(aspatial data). The project consists of a multimedia tool, a capital budgeting tool, a scheduling tool, and finally a grave identification tool.

New York Stock Exchange is the prototype of the exchanges. It is one of the national exchanges. It deals with all kind of securities. NYSE is considered as one marketplace for all kinds of trading transactions. In addition, its presence has largely
contributed to the development of trading activities. Further, numerous factors do affect it ,and hence affect the price level of
stocks.
The purpose of this project is to discuss and analyze the different factors that determine the NYSE, such as inflation, GNP,
interest rate, and Federal Budget deficit. It will also determine the
type of relationship that exist between each factor and the
marketplace and the degree of impact of each factor on the stock prices level.
To be more elaborated about the historical background of
NYSE , a library research was conducted. In addition, this research includes information about the theories advanced on the marketplace.
Also, a brief review is added about the market crash that took place in October ,1987,description of that black day, causes and
consequences. For a better understanding the movements of the price level in
the NYSE, a regression analysis was conducted in order to test the
degree of impact of each economic factor on the marketplace. Four
main factors are taken in this paper: inflation, Gross National
Product, Three Months Treasury Bills rate, and the Federal Budget
deficit. S&P 500 is considered as the representative of the stock price level.
According to the results of the analysis, the stock prices are positively affected by inflation and GNP. Whereas it is negatively affected by the interest rate and the deficit. These factors can be
considered as the determinants of NYSE. Each factor has its own degree of impact. Thus investors must take these results into consideration while making up their minds towards investment.

The following research project is intended to evaluate the prospects of the Lebanese capital
market playing a role on a regional level. The analysis is based on many research papers
done by leading international investment firms, in addition to local economic and
investment research. The statistics used are of varying levels of accuracy, and therefore, much data have been used solely to make inferences on general economic and monetary
trends affecting the Lebanese capital market. This paper is divided into five parts. Part four comprises the bulk of the analysis, and
highlights Lebanon's main economic and financial strengths and weaknesses, in light of their impact on the capital market, along with the regional opportunities and threats influencing the evolution of this market. The first part gives the reader a general
background on Lebanon's economic and financial conditions prior to 1975. The second
part assesses the economic and financial damage inflicted on Lebanon during 15 years of civil war. The third part profiles the main pre-requisites for a successful capital market.
Lastly, the fifth part provides a conclusion as to the chances of the Lebanese capital market becoming one of the region's leading markets. The reader is left with a summary of factors, both positively and negatively affecting the evolution of the Lebanese capital market into a
regional market. Recommendations to remedy some of Lebanon's economic, monetary and
fiscal weaknesses are a vital outcome of this research effort, and are included in the last
section. While constructing the above analysis, many financial experts were interviewed, giving this paper more depth and a clearer direction. However, a true evaluation of economic and
capital market trends requires much more extensive research, and the adoption of quantitative models, which are beyond the purpose of this research project.

Why to leave the success and survival of a hospital to chance? A well-thoughtout
plan, with problems identified, and a course of action agreed upon do not
guarantee success, but greatly decrease the chances of failure.
In light of the turbulent environment, both within and outside the hospital,
hospital directors should pursue an approach to meet present and future changes and
challenges. This approach is but the Strategic Management Practice that involves
monitoring environmental changes, developing the strategic plan, implementing the
plan, and evaluating the results. Innovative strategic planning and strategic
management will enable the hospital not just to maintain but to expand its role in
providing primary as well as preventive health care to all those in need. Although the
stress is very much on what should occur in the future, it should be remarked that it is the steps taken today which dictate whether or not the future becomes a reality. Therefore, strategic management should be firmly grounded in the realities of today and must have a clear vision of the future as well.
The aim of this study is to assess the practice of strategic management in
private non-profit hospitals in Greater Beirut. Since strategic management is
primarily a top management function, private in-depth interviews through the use of a
structured questionnaire were done with the directors of ten private non-profit
hospitals. Moreover, an interview with the General Director of Ministry of Health,
Dr. W. Ammar was done to back up the findings.
The results of this study reveal that most of these hospitals practice strategic management on an informal basis. Moreover, many of them are practicing in fact, the long-range planning, a previous stage in the development of management towards
strategic management. Thus, strategic thinking and not really strategic management
exists. Nevertheless, these hospitals accommodate with the environmental changes and are driven by the underlying problems of the existing health care system in Lebanon. Thus, the need to overcome these problems by altering the present situation
requires more than the existing strategic thinking or informal strategic management.
It requires the action incurred by establishing a formal process of strategic management.
Further, these hospitals, aiming at providing the best quality of care at the lowest cost, are highly recommended to cooperate and collaborate together in order to
overcome the future common threat, the competition with Israel and the Arab region once the Peace Treaty has been signed. The Lebanese government will not be able
anymore to protect its market once the whole region becomes one unified big market.
Finally, a national health planning strategy from the government is highly
needed in order to regulate the hospital industry in Lebanon. According to Dr.
Ammar, this strategy will be implemented in the coming years. Consequently, these
hospitals will be able to practice strategic management in a more regulated
environment and on a formal basis.

We analyze the Software Engineering practices in Lebanon and provide suggestions
for local requirements analysis and software testing standards. The analysis is based
on a questionnaire answered by local Software Engineering companies. The analysis
results show great lack in documentation and standardization. Our suggested local
standards are based on a selection of international standards namely the ISO, British
and IEEE Software Engineering Standards. These standards would improve the local
software quality and guide the local software engineers in producing internationally
marketable software products.

With the growing and complexity world of business, anything one tries
to accomplish on budget requires a thorough plan. It requires good
management to identify and correct problems before they impact his/her budgets or schedule. And good communication to keep his/her team focused on the right objectives at the right time.One tool that has become an absolutely necessary expedient in implementing project management techniques is the computer. The impact of computers and expand information capabilities has been evident within many fields. Considering information as a valuable resource and using technology to
generate reliable and fast information have achieved significant cost reductions Microsoft Project has been widely recognized for more than five years
as the easiest- to- use project management software. Moreover, Microsoft Project shares data easily with other programs in Microsoft Office. Beneath
this ease of use is a powerful planning, analysis, and management tool that lets one builds enterprise-wide, mission-critical project management solutions. Based on that, the purpose of the study was to see the awareness of the Lebanese managers toward the advantages of using Microsoft Project. In addition, it was to see the difference between the professional users and the non professional users of Microsoft Project. Also, it discussed the factors that most likely affect on their attitude toward using it.
It is hoped that this effort will assist in furthering the studies aimed at
improving level of computer usage by project manages and others. In addition,
amid at investigating the factors that are most likely to playa critical role in using Microsoft Project.

At the end of the Twenty-first century, consumers are bombarded each day by hundreds of advertising messages intended to motivate them to buy something. However, new techniques developed by marketers do not allow individuals to become aware of much of the information delivered because it is below the threshold for conscious perception. Nonetheless, some embeds used by marketers could be
consciously perceived once they are pointed out. Thus, this information presentation takes place at two different levels of consumer awareness. At the upper most level, consumers will have full conscious awareness of this information. They are paying attention and she or he should be able to remember and state the nature of the
information. At the second level, subliminal information would be transmitted where
the consumer is assumed to have no conscious awareness.
This research paper was conducted with the assumption that all people might
be affected by marketers stimuli. Thus, there are some basic factors and drives common among the human being, i.e. sex motivation, violence, security needs, ego satisfaction ... etc. As a result, marketers are continuously trying to understand what
motivates people in making their purchase decision (motivational research) while
seeking to explore the subconscious.
The purpose of this study was to find whether the inclusion of embed words or symbols can have any effect on consumer behavior and intention to buy. This will be followed by an investigation to find out if these can lead to any reaction (cognitive,
affective or sexual) upon the consumers' feelings.
It is hoped that this effort will assist in furthering the studies aimed at
improving marketing communication messages and building consumer awareness in
Lebanon as to the factors that might affect buying behavior.

The Public Schools Regrouping project is a project initiated by the Ministry of
Education. It involves managing and planning (such as regrouping) of schools distribution in Lebanon with the aim of satisfying educational, economical and
national criteria. In this work, we have developed a software tool referred to as the
Schools Regrouping Decision Support System (SRDSS), that consists of four components: (a) Schools database that contains information about students, teachers,
and schools, (b) Towns Database that contains information about the town's
population and geographical location, (c) Schools Regrouping Algorithm, and (d)
Geographical Information System that help in visualizing data and the algorithm's
results.
The original contributions of this work are: (a) the formulation of the schools
regrouping problem as a weighted graph problem, and (b) the application of the pcenters schools regrouping algorithm to determinehow the current schools, in a userdefined
region, can be regrouped to a smaller user-defined number, p, of schools such
that user-defined criteria are satisfied.
The experimental application of the algorithm to the Aley Caza shows the
flexibility of the algorithm in supporting regrouping decisions and gives good results
that are clearly consistent with the stated criteria.

It is well-known that "software engineers" in Lebanon do not use standard methods. The common belief is that using standards might add to the cost of the software. This work goes against the common belief and emphasizes software quality and documentation. In this project, we propose standards for software development in
Lebanon and present guidelines for using these standards. The proposed standards are based on IEEE's and ISO's standards and on personal experience. They are simplified
and tailored to suit the small- to minimum-size activities of lebanese software
organizations. The proposed guidelines are presented in a checklist easy-to-use fashion.

Based on a study conducted on the Lebanese software firms, it was found that the development process is applied based on subjective assessments and self made rules,
documentation and planning issues are not the main concern, and assuring quality in
software is regarded as a burden that delays the production of software and increases its cost. This showed the need of the Lebanese firms for a quality system to be
introduced into their companies. The quality system is suggested for small-to-medium
scale Lebanese firms in order to attain an acceptable level of quality in the software production industry. It is based on a selection of international standards namely the
ISO and IEEE SQA standards. It contains and focuses on the minimum activities to be carried out in each of the development phases. The aim is to produce a simple and direct quality system integrated into the entire development phases and accepted by the
Lebanese firms' managers. A case study is also presented, where the suggested quality system is implemented at a small scale Lebanese company.

A huge variety of drinks exist in the beverage market. Every consumer has a
different and specific taste and choice. One might prefer non alcoholic
drinks to alcoholic ones, fizzy to plain, sweet to bitter, fun drinks to food drinks, natural to artificial ... etc. However, the main focus of this research project is on alcoholic drinks. In the liquor sector, the life cycle of each
market starts from a seed stage, to later pass on to a growing stage, to then start the mature stage and finally end up in the post mature stage.
There is practically no information on liquor psychographics (consumer liquor habits) available in Lebanon, and no previous studies have been made in order to show which are the products that are growing, stable or
declining. Therefore, the main purpose of this study is to evaluate and
compare consumer liquor habits in a post mature market, the USA, to a
growing market, Lebanon, so one may examine and speculate on the actual stage that Lebanon has reached a research study done by Heublein Inc. in the USA proves that due to its post mature stage, the USA drinks' industry has faced a very strong need of innovation, and has started producing new products called alcopops (drinks
with new and colorful packaging and low alcohol content) in order to attract new consumers. Such products are indeed attracting new consumers, mainly
teenagers of 15 years old, which is increasing the under age drinkers and the alcoholism rate in the USA. This research project is based on several interviews made in Lebanon with
both marketing executives in the liquor sector and research companies, and on questionnaires made to youngsters (university students) and qualified bartenders. The information arising from all the mentioned sources helps in accurately measuring the actual situation of the liquor market, and in describing the fUture situation of the Lebanese market. Taking into
consideration the problems arising in post mature markets like the USA, and
speculating on the actual situation of the liquor situation in Lebanon
through this study, one may come up with valuable recommendations to both the distillers and to the government in order to avoid eventual problems,
similar to those arising in other markets.

This project is a study of the space density of a file and how it affects retrieval time. The number of blocks that are retrieved when a query is made to the
document is used as a measure of response time. The space density is an
indication of how close related records are placed. The hannning distance of a
file is used as a measure of space density. A sequencing algorithm based on
threshold values that reorders records in a file so as to increase average record
similarity is used to obtain varying space densities. Simulation experiments
conducted proved that a great reduction in response time is yielded after the
restructuring of a file with a reasonable amount of work required in sequencing.
Other terms such as block size and terms in a query which affect response time are studied. Results from the experiments are shown graphically. Statistical methods are used to confirm the experimental results.

We have developed a software tool that draws flow graphs for C programs and displays
testing coverage information in a graphical and user friendly way. The tool helps the
software engineer/maintainer to get a feel for the testing process and tables generated
by any other testing tool. It also provides a framework for experimenting with
regression testing algorithms. Within this framework, we have implemented a reduction based regression testing algorithm. This algorithm assumes that the testing criteria are
given by a set of requirements with associated subsets of test cases and then tries to
satisfY these requirements with a minimum of test cases. We have used the tool to compare a number of regression testing algorithms. The comparative study uses a variety of small-size and medium-size modules and is based on quantitative and
qualitative criteria. The comparison results show that the six algorithms are suitable for different requirements of regression testing. For medium-size modules, the adapted
firewall algorithm is the slowest. The genetic and simulated annealing algorithms produce the least number of retests, followed by reduction, then incremental, slicing, and adapted firewall algorithms.

Without measurements (or metrics) it is impossible to detect problems early in the software process. 'Software Metrics' can serve as an early warning system for potential problems. In this project, we propose complexity metrics for small business applications developed using MS Access. These metrics can be used for estimating
the effort and duration of a project's implementation phase. The proposed metrics are
base on Function Point metrics with certain modifications that make them applicable
to relational database languages.

We introduce the subject of software measurement to software practitioners in Lebanon, and we propose a comprehensive process-oriented approach for an effective use of
software metrics. We therefore overview related areas, for instance the Goal-QuestionMetric
paradigm and the Capability Maturity Model. We also present a set of software metrics. To be of practical use, we propose an exhaustive Software Metrics Programme to
guide a typical Lebanese software company through the initiation and implementation of
software metrics in its environment. We finally present a case study of the implementation
of such a metrics initiative in a Lebanese company.

Lebanon nowadays is surviving in an age of rapid technological advancement.
At this stage , the Lebanese labor force is considered a primary raw material in the
process of reconstruction and rehabilitation. However, for them to be efficient and
effective , the human resources should possess the up-to-date skills and knowledge
which might be guaranteed by continuous training and development. To conclude, human preparation is needed.
The purposes of this study were to assess the interaction between the trainees
and the efforts made by the Lebanese- private training firms and to study the
advantages and shortcomings of these firms. It also intends to assess the need of the Lebanese labor force for Lebanese- private training finns. As to the hypotheses to be
tested, they are two. First of all , these is a positive correlation between the efforts made by the training firms and the labor force performance. Second, the overall all training approach followed by these firms is the most effective.
To elaborate on the historical background of training and training firms, a
library research was conducted. To study and test the above mentioned purposes and
hypotheses, the SPSS (Statistical Package for Social Sciences) was used. One-Way ANOVA , crosstabulation, regression analysis, Chi-square analysis, and correlation
analysis were performed.
According to the results of the analysis, the Lebanese private training firms
still have certain cons that need to be overcomed in order to move towards more
effective training approach. These training firms have to concentrate more on the practical rather than theoretical aspects of training, modifying the training material
brought from outside to suit our conditions, and on offering training that pertains to
the real work setting and environment of the trainees.
