Thematic Study of “Ayman al-ʿAtūm”’s Prison Novels
No full textThe novel is a prose genre whose origins are thought to be based on epics and whose first examples emerged in Europe. The development of the novel genre in Arab geography has experienced some difficulties. Some types of novels with unique styles were prevented from being distributed and published by various censors. The genre that calls itself prison literature deals with the life stories of prisoners in prison, their torture, and the hardships they experience. The general themes of these novels are freedom, exhaustion, despair, and resistance. Although works have been written in this genre in the West, this genre also has a special place in Arabic literature. Authors such as Abdurrahman Munif, Majid Suleiman, Mustafa Khalifa and Ayman al-ʿAtūm stand out in Arabic literature. Ayman al-ʿAtūm, whose novels feature an Islamist aspect, is one of the most important figures in modern Arabic literature. In both his novels Yā Sāhibeyi’s-Sijn and Yāsmeūne Hasīsehā, he experienced and fictionalized the punishment of rebelling against authority or holding different views in societies ruled by authoritarian regimes and in which democracy exists only in words. In addition to being an engineer, the author is an academic and a man of letters
Optimal scheduling and resource utilization for repetitive construction projects
No full textRepetitive construction projects require construction crews to repeat their work in a number of locations in the same project, moving from one location to the next. Scheduling this type of projects often requires maximizing work continuity for these crews while reducing the project duration and the use of overtime. The main goal of this study is to present the development of novel models for optimizing the scheduling of repetitive construction projects that is capable of accomplishing these planning objectives. To achieve this goal, the research objectives of this study are to develop (1) a novel heuristic and computationally-efficient scheduling model for repetitive projects that minimizes both the project duration and crew work interruptions; (2) an innovative optimization model for scheduling repetitive construction projects that is capable of searching for and identifying optimal schedules that minimize project duration, work interruptions, and interruption costs; and (3) a novel multi-objective optimization model for repetitive construction projects that generates optimal tradeoffs among project duration, work interruptions, and overtime use.
The performance of these developed models was analyzed and verified by comparing their results to those generated by existing models. The results of this analysis illustrates the novel and unique capabilities of the developed models in generating optimal tradeoffs among project duration, work interruptions, and overtime use. These novel capabilities are expected to provide much needed support to planners of repetitive construction projects and enable them to (i) minimize project duration, (ii) maximize crew work continuity, (iii) minimize interruption costs, (iv) minimize the use of overtime hours; and (v) reduce the required time and effort to perform the scheduling computations for large-scale repetitive construction projects by using a computationally efficient heuristic scheduling model.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-08-01The student, Ayman Altuwaim, accepted the attached license on 2018-07-04 at 11:06.The student, Ayman Altuwaim, submitted this Dissertation for approval on 2018-07-04 at 11:09.This Dissertation was approved for publication on 2018-07-05 at 16:07.DSpace SAF Submission Ingestion Package generated from Vireo submission #12628 on 2018-09-27 at 11:33:14Made available in DSpace on 2018-09-27T16:45:31Z (GMT).

Corporate Disclosure on Anti-Corruption Practice: A study of Social Responsible
No full textThis paper seeks to determine the extent of anti-corruption information disclosure in the sustainability reports originating from Gulf countries. Focus primarily on the fight against corruption, this study utilizes a deeply-rooted content analysis technique of corporate sustainability reporting, covering 66 Gulf Cooperation Council (GCC) firms during 2014. Strengthened by the application of institutional theory, insight into the results points to a state of limited maturity regarding the disclosure of anti-corruption procedures in the region. More specifically, the results highlight the compliance in the reporting of conduct code, while reporting information on whistle-blowing was significantly less in comparison. Firms in Qatar and UAE ultimately release better informed reports; inclusive of detailed information on internal anti-corruption practices
محددات قصر القامة عند الأطفال في مصر : مزيد من التحليل للمسح الديموغرافي والصحي ٢٠١٤
No full textWhile proper nutrition prevents diseases and promotes good health, poor nutrition in the first 1000 days of life can lead to stunted growth. The prevalence of childhood stunting in Egypt has increased after the millennium with the prevalence rate being above 20% in the last twenty years. To investigate any significant association between childhood stunting and different demographic, socioeconomic, biological and immediate determinants in a nationally representative sample of Egypt. Data from the 2014 Egypt Demographic and Health Survey was used. Pearson’s Chi square test was run to discover any association and the generalized logistic regression approach was used in the analyses to generate odds ratio of the association between childhood stunting and the studied determinants. Stunting was found to be significantly associated with different determinants. Children living in Rural and Urban Upper Egypt were more likely to be stunted than children living in other regions in Egypt. Children from the richest quintile were more likely to be stunted than children from lower quintiles. Children with no health insurance coverage were more likely to be stunted than children who have health insurance. Male children were more likely to be stunted than female ones. Children who had normal weight at birth were less likely to be stunted than children who had low weight at birth. Stunting was found to be significantly associated with demographical, socioeconomical and biological factors. Egypt needs a strategy with multi-sectorial approach in order to address stunting in children under the age of five
The Factors Influencing Corporate Social Responsibility Disclosure in the Kingdom of Saudi Arabia.
No full textBACKGROUND: In today’s world of increased awareness regarding the concepts of
corporate social responsibility (CSR) and corporate governance (CG), many firms in
the developed countries consider noncompliance with CSR and CG standards as an
important source of risk to their reputations with stakeholders. OBJECTIVE: The aim
of this study is to investigate the relationship between the corporate social responsibility
disclosure (CSRD) index and corporate factors, namely, board size, board
independence, board meetings, CEO duality, a firm’s size, leverage, profitability and
age. This is the first known study in the case of Saudi Arabia to use the GRI 4th edition
indicators to construct the CSRD index and evaluate Saudi listed firms. Results: The
results show that profitability and size factor have positive and significant association
with CSR disclosure in listed Saudi firms. While CG characteristics have no impact on
CSR disclosure except board independence which has a negative impact. Conclusion:
The average of CSRD index among Saudi firms is too low, it is about 11% that means
Saudi firms disclose 11% of the information that they have to provide for stockholders
according to GRI guidelines. Furthermore, the study concludes that the most polluted

Modelling the behaviour of unsaturated non-active clays in saline environment
No full textThe chemical composition of pore fluid and matric suction rule the mechanical behaviour of soils. In case of clays, their fabric changes in line with those variables. Since both the increase in matric suction and salinity cause a transition from an open to a close microstructure of low and medium activity clayey materials, a unique framework could tackle problems where salinity and saturation changes are expected. This paper presents a simple elasto-plastic model capable of reproducing the behaviour of unsaturated clayey soils in saline environments. Changes in the pore fluid composition are addressed through the use of osmotic suction as a variable. The proposed model extends the Barcelona Basic Model for partially saturated soils to consider the effect of osmotic suction. The model, implemented in the Thebes code, is calibrated for Boom Clay. The reproduced tests include mechanical loading at different matric and osmotic suctions in oedometric conditions, as well as more complex chemo-mechanical stress paths. Despite the simplicity of the formulation, the agreement between the experimental results and the simulations is encouraging. It seems that the modelling approach addresses the most important features of partially saturated soils with saline pore fluid which are slightly or moderately expansive

The Determinants of Dividend Policy: Evidence from Malaysian Firms
No full textThe aim of this study is to investigate the relationship between dividend payout ratio in Malaysian firms with profitability, size, growth opportunities, free cash flow, business risk and market to book value. The paper used a sample of 284 firms listed on the Kuala Lumpur Stock Exchange (KLSE) from seven sectors viz., Consumer Products, Industrial Products, Construction, Finance, Technology, Properties, and Telecommunication. In order to decipher the relationships as stated above, multivariate regression analysis is used to test the hypotheses. The study found that at the pooled data level for All sectors, free cash flow, return on assets, return on equity, earning per share, market to book value and market capitalization have significant positive correlation with dividend payout ratio.
The variable Beta,however,has a strong negative correlation with dividend payout ratio. The findings however differ from sector to sector; results reflect that Market
capitalization; Beta, ROA and ROE are the common variables which have influence on DPR across various sectors except in technology sector where as the variable Market
capitalization is not significantly associated with DPR. Similarly, ROA, which is significant determinant variable of DPR in four sectors like Construction,Consumer Products, Properties and Telecommunication Sector,it has no influence on the dividend payout ratio of the companies in the Industrial, Technology and Finance sectors
