The Role of the Islamic Waqf in the Equitable Distribution of Wealth in Jordan (2015-2020)
This study aims to shed light on the role of the Islamic Waqf in the equitable distribution of wealth in Jordan between 2015 and 2020. It is the role of the Ministry of Awqaaf and Islamic Affairs as the official government body responsible for the Islamic Waqf in Jordan whose endowment funds directed to mosques, health, education, needy and public sector. The results showed that a disproportionate percentage of spending was directed to the mosques, and the need for the Islamic Waqf to allocate the funds raised from the rich people to support the poor people, and vulnerable population as well as the relevant health education services
Libraries in major universities in Lebanon.
This paper puts the contemporary situation of some Lebanese university libraries in a broader context. It introduces the country, and outlines its higher education system, library science education, professional association, and publishing activity. It reviews the varying situations in the libraries of 3 selected Universities - the American University of Beirut, the Beirut Arab University and the Lebanese University, and contrasts this with other university libraries in the Arab world. It adds to the body of published knowledge about the current situation in respect of management, staffing, buildings, automation, information retrieval, bibliographic records, online and CD databases, and document delivery. The limited published information was supplemented by interviews with a number of staff to elicit their views on the current situation and a survey of students experiences of using the libraries. With the exception of the American University of Beirut, the libraries facilities and services are not comparable to best practice in other Arab countries or the western world. This work highlighted some of the difficulties encountered by the libraries and their users, perhaps not entirely the result of the civil war, but indicates that plans are in place to take the libraries to the next step of development
Development and validation of spectrophotometric and spectrofluorimetric methods for determination of cilnidipine
Purpose: To develop simple and reliable quantitative methods for the determination of cilnidipine (CLD) in pharmaceutical tablets.Methods: Two simple and sensitive methods (spectrophotometric and spectrofluorimetric) were developed for the determination of cilnidipine (CLD) in pure form and in a pharmaceutical preparation. Spectrophotometric method (A) is based on oxidation of CLD with a known excess amount of Nbromosuccinamide (NBS) in acidic medium, followed by addition of methyl orange indicator and absorbance measurement at 510 nm. The spectrofluorimetric method (B) is based on oxidation of CLD to cerium (IV), followed by measurement of fluorescence emission of Ce (III) at 350 nm. Factors that affect the performance of the two methods were studied and optimized.Results: The spectrophotometric and spectrofluorimetric procedures were successfully used for measuring CLD levels in pharmaceutical dosage form, in the ranges of 2.0 - 25.0 and 0.25 - 11.2 μg/mL, at detection limits of 1.05 and 0.13 μg/mL, respectively. There were no significant differences between the proposed methods and a standard reference method (p < 0.05).Conclusion: The developed methods provide simple and reliable procedures for quantitative measurement of CLD in bulk and tablet forms.

REVITALIZING THE BORDERLINES THROUGH ARCHITECTURE OF GREEN NETWORKING - CASE STUDY: BEIRUT, LEBANON
Borders are an essential part of cities and countries, and they can create both physical and cultural divides. Inner-city borders can lead to social isolation and inequality, which can contribute to tensions and conflicts. Borders around the world have become a symbol of conflict, racism, fear, inequity, and division. One single line could divide between opportunity and hope and poverty and oblivion. Accordingly, some borders create social isolation between various cultures in cities that increase socio-political problems and remove urban connectivity. Green networking involves using urban green spaces, such as parks and gardens, to connect different areas of a city and facilitate movement and interaction between people. This research aims to examine the impact of inner-city borders on social integration between different cultural groups by using green networking to break down barriers and promote social interaction. The study will contribute to a better understanding of how urban green spaces can promote social integration and reduce inequality in inner cities. The study will use scientific methodology, including site visits, experimental examinations, and analytical research, to provide a comprehensive understanding of the borderline area of research
Serum vitamin D in patients with mild cognitive impairment and Alzheimer's disease
Objectives: To determine the relevance of Mini-Mental State Examination (MMSE), serum 25-hydroxyvitamin D (25(OH)D3), and 1,25(OH)2D3 concentrations to mild cognitive impairment (MCI) and various stages of Alzheimer's disease (AD). Materials and Methods: The study included 230 participants (>74 years) allocated to three main groups: 1-healthy subjects (HS, n = 61), 2-patients with MCI (n = 61), and 3- patients with Alzheimer's disease (AD) subdivided into three stages: mild (n = 41), moderate (n = 35), and severe AD (n = 32). The cognitive status was evaluated using MMSE. Serum 25 (OH)D3 (ng/ml) and 1,25(OH)2D3 concentrations (pg/ml) were determined by competitive radioimmunoassay. Results: MMSE scores and 25(OH)D3 were decreased in MCI and all stages of the AD in both genders. MMSE variability was due to gender in HS (11%) and to 25(OH)D3 in MCI (15%) and AD (26%). ROC analysis revealed an outstanding property of MMSE in diagnosis of MCI (AUC, 0.906; CI 95%, 0.847–0.965; sensitivity 82%; specificity, 98%) and AD (AUC, 0.997; CI 95%, 0.992–1; sensitivity, 100%; specificity, 98%). 25(OH)D3 exhibited good property in MCI (AUC, 0.765; CI 95%, 0.681–0.849; sensitivity, 90%; specificity, 54%) and an excellent property in diagnosis of AD (AUC, 0.843; CI 95%, 0.782–0.904; sensitivity, 97%; specificity, 79%). Logistic analyses revealed that, in MCI, MMSE could predict (or classify correctly) with 97.6% accuracy (Wald, 15.22, β, −0.162; SE, 0.554; OR = 0.115:0.039–0.341; p =.0001), whereas 25(OH)D3 with 80% accuracy (Wald, 41,013; β, −0.213; SE, 0.033; OR = 0.808: 0.757–863; p =.0001). 25(OH)D3 was the only significant predictor for the severe AD and contributed to MMSE variability. Age and gender were significant predictors only in the moderate AD. In patients with MCI, 25(OH)D3 and 1,25(OH)2D3 were correlated men, but in case of the AD, they were correlated in women. Conclusions: MMSE and serum 25(OH)D3 concentrations could be useful biomarkers for prediction and diagnosis of MCI and various stages of the AD. The results support the utility of vitamin D supplementation in AD therapy regimen. © 2018 The Authors. Brain and Behavior published by Wiley Periodicals, Inc
A Comparative Taxonomy of Parallel Algorithms for RNA Secondary Structure Prediction
RNA molecules have been discovered playing crucial roles in numerous biological and medical procedures and processes. RNA structures determination have become a major problem in the biology context. Recently, computer scientists have empowered the biologists with RNA secondary structures that ease an understanding of the RNA functions and roles. Detecting RNA secondary structure is an NP-hard problem, especially in pseudoknotted RNA structures. The detection process is also time-consuming; as a result, an alternative approach such as using parallel architectures is a desirable option. The main goal in this paper is to do an intensive investigation of parallel methods used in the literature to solve the demanding issues, related to the RNA secondary structure prediction methods. Then, we introduce a new taxonomy for the parallel RNA folding methods. Based on this proposed taxonomy, a systematic and scientific comparison is performed among these existing methods
Legal protection of civilians and prisoners in non-interstate armed conflict: a study in international humanitarian law
This thesis is concerned with the controversial problem of the legal protection of civilians and prisoners in non—interstate armed conflicts, i.e., civil wars and wars of national liberation. It examines the lengthy discussions which took place at the Diplomatic Conferences of Ceneva in 1949 and 1974 to 1977, and evaluates the outcome.
Chapters One and Two examine the problem with regard to civil wars, while Chapter Three examines the problem with regard to wars of national liberation. Chapter Four examines the fundamental principle of distinction between combatants and non—combatants, including the problem of prisoner—of—war status in wars of national liberation, as well as the distinction between civilian objects and military objectives. Chapter Five examines the more ctai1ed rules affording protection to the civilian population and civilian objects against effects of hostilities, while Chapter Six examines the field of application of these rules with special reference to their application by a Party to the conflict to its own territory which is under the control of' the adverse Party. The last, Chapter Seven, is a general assessment of the major solutions within the framework of the processes of law—making, law—determination, and law enforcement
LEADERSHIP STYLE AMONG MIDDLE MANAGERS IN SAUDI MINISTRY OF HEALTH
Background: Middle managers within ministry of health act under continuous pressure from board level to be successful leaders of today's and tomorrow's healthcare service. Leadership styles are important factors among middle managers to retain employees in organizations and to ensure a high quality of practice.Aims: Two main aims: to examine the leadership style(s) of middle managers as perceived by them as leader from different departments of the Saudi Ministry of Health, and to examine the leadership style(s) of the middle managers as perceived by their subordinates as raters from different departments of the Saudi Ministry of Health.Materials and methods: A cross-sectional descriptive design was used to answer the research questions. A convenience sample of 121 participants, 30 middle managers and 91 subordinates, who were recruited through different departments at Saudi Ministry of Health during the period of June 2010 through September 2010.Participants were subjected to Univariate and Multivariate analysis. The Multifactor Leadership Questionnaire (MLQ) was used to collect data.Results: the mean ratings of all four components of transformational leadership for the subordinates and middle managers were between 2.90 to 3.29 .The mean ratings for contingent reward and management by exception active were 3.30 and 2.50 respectively and this was well within the optimum range as suggested by Bass. Management by exception passive and laissez-faire showed mean ratings of 1.67 and 1.25 respectively. The correlation coefficients among transformational leadership style and each variable of, satisfaction, effectiveness and extra effort for raters and leaders sample was high positively reached (r = .72, p< 0.05) , (r = .81, p< 0.05) , (r = .80, p< 0.05) respectively, The correlation coefficients among transactional leadership style and each variable of, satisfaction, effectiveness and extra effort for raters and leaders sample was high positively reached (r = .20, p<0.05) , (r = .44, p< 0.05) , (r = .35, p< 0.05) respectively, and The correlation coefficients among laissez -Faire leadership style and each variable of, satisfaction, effectiveness and extra effort for raters and leaders sample was high negatively reached (r = -.48, p< 0.05) , (r = -.46, p< 0.05) , (r = -.43, p< 0.05) respectively. There are agreement between leaders and raters on transformational, transactional and laissez-faire as distributive in Saudi Ministry of Health in kingdom of Saudi Arabia. The result showed there was no significant difference on the MLQ factors for raters and Leader due to gender, marital status, and age. Also , the analysis showed significant differences among raters’ opinions due to work experiences as contingent reward and extra effort in favor of raters who experience of them more than ˃ 6 Month, and finally, the analysis showed there significant differences among raters’ opinions due to period working with leaders as transformational, idealized Influence attributed, inspirational motivation, intellectual stimulation, contingent reward, and effectiveness in favor of raters who working with leaders for a period between 6 months - ˂ 1 year, but significant differences among raters’ opinions due to period working with leaders as Laissez –Faire in favor of raters who working with leaders for a period between 1 year - 2 years.Conclusions: transformational leadership can contribute a lot to the effectiveness of organizations and that there is a need for further investigation of leadership at different levels
Approach to attributed feature modeling for requirements elicitation in Scrum agile development
Requirements elicitation is a core activity of requirements engineering for the product to be developed. The knowledge that has been gained during requirements engineering about the product to be developed forms the basis for requirement elicitation. The agile approach is becoming known day by day as the most widely used innovative process in the domain of requirements engineering. Requirements elicitation in agile development faces several challenges. Requirements must be gathered sufficiently to reflect stakeholders' needs. Furthermore, because of the development process, requirements evolve, and they must be adequately treated to keep up with the changing demands of the market and the passage of time. Another challenge with agile implementation is handling non-functional requirements in software development. Addressing non- functional requirements is still a critical factor in the success of any product. Requirements prioritization is also one of the most challenging tasks, and it is uncommon for requirement engineers to be able to specify and document all the requirements at once. This paper presents an approach for requirements elicitation in scrum-based agile development. The approach operates with the feature modeling technique, which is originally used in the Software Product Line (SPL). One of the most important proposed extensions to Feature Models (FMs) is the introduction of feature attributes. Our method uses attributed FMs to consider both functional and non-functional requirements as well as requirement prioritization. For the evaluation purposes, we have demonstrated our approach through two case studies in different domains of software product development. The first case study is in the domain of education, and the second one is in the domain of health care. The results reveal that our approach fits the requirements elicitation process in scrum agile development.Bourns College of Engineering, University of California, Riverside(undefined
