Assessing the Digital Divide Status of the Jordanian Telecentre  [PDF]
Dmaithan Abdelkarim Almajali, Mahmoud Maqableh, Ra’ed Moh’d Taisir Masa’deh
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2015, DOI: 10.4236/ijcns.2015.811039
Abstract: This study investigates the status of digital divide amongst Jordanian Telecentres. The objective of this study is to analyze the impact of the perceived usefulness, the perceived ease-of-use and the facilitating conditions on the behavioral intention of employees. In addition, the study investigates the effect of the three mentioned factors on the user acceptance while the behavioral intention on the user acceptance is used as a mediating factor. The proposed research model was validated by distributing 150 survey questionnaires to the Telecentres in Jordan. Structural equation modeling (SEM) technique was used to analyze the results. One of the main limitations of this study is that the results cannot be universal since the study was limited to Jordan. Similar study needs to be conducted in different courtiers to either support or negate our results.
Applying the Triangulation Approach in IT – Business Strategic Alignment and Sustainable Competitive Advantage
Dmaithan Abdelkarim Almajali,Zulkhairi Md Dahalin
IBIMA Business Review , 2011,
Abstract: While researchers have encouraged more research on the causal chains between information technology investments and Business performance, the results of empirical studies have been inconclusive. This is partly due to the exclusion of IT-business strategic alignment. This study has examined the impact of IT-business strategic alignment antecedents in terms of leadership, structure and process, service quality, and value and belief on IT business strategic alignment in terms of alignment gap, followed by the impact of IT-business strategic alignment on sustainable competitive advantage. In order to explore the above research relationships, the study further utilizes the positivism paradigm by applying a mixed research method both quantitative and qualitative data. Such triangulation would help to provide more insight into the issues studied in this research. Particularly, this study has tested the research model by conducting 172 survey questionnaires with public shareholding firms in Jordan. After that, the study conducted several follow-up interviews in Jordan in order to further validate the research results. Thus, the results obtained from the structural equation modeling (SEM) technique and supplementary qualitative analysis of the interviews offer a valuable insight into the research. However, the universal applicability of this research may be limited due to the fact that the results are based only on the cross-sectional data from the Jordanian public shareholding firms. Consequently, further research is needed with regards to several countries since this would help to advance understanding of the IT-business strategic alignment issue and the conditions and outcomes of achieving it in different contexts.
Factors influencing IT-Business Strategic Alignment and Sustainable Competitive Advantage: a Structural Equation Modelling Approach
Dmaithan Abdelkarim Almajali,Zulkhairi Md Dahalin
Communications of the IBIMA , 2011,
Abstract: Preceding research attributed the lack of direct causal impact of Information Technology (IT) on firm’s sustainable competitive advantage. Numerous missing links include antecedents of the IT-business strategic alignment (also known as strategic alignment) and the sustainable competitive advantage. Furthermore, reviewers of recent literature have called for more research into the factors that affect strategic alignment, and the linkage between alignment and sustainable competitive advantage. In this paper, we develop and empirically test specific forms of management structures and processes which are required to drive strategic alignment. Further, we propose a causal-chain model to examine the impacts of six antecedents on strategic alignment. The data are collected from over 172 Jordanian public shareholding firms. Using structural equation modeling for data analysis, this study finds general support for the hypotheses that leadership, values and belief, IT managerial resources, service quality, and IT implementation successes significantly impact IT-business strategic alignment. However, no relationship is found between structure and process and strategic alignment.

Abstract: This study investigates the status of e-SCM and performance among Jordanian manufacturing sector. The objective of this study is to analyze the impact of trust and communication on the e-SCM usage. Moreover, the study investigates the effect of the trust and communication on the firm’s performance while the e-SCM usage is used as a mediating factor on firm’s performance. The proposed research model was validated by distributing 250 survey questionnaires to the manufacturing sector in Jordan. Structural equation modelling (SEM) technique was used to analyze the results. One of the main limitations of this study was that the results could not be universal since the study was limited to Jordan. We discussed the implications of our results for research and practice.
La révolution tunisienne de janvier 2011 : une lecture par les déséquilibres du territoire
Abdelkarim Daoud
EchoGéo , 2011,
Abstract: A travers une approche rétrospective, le présent papier tente d’apporter une réflexion sur l’évolution des politiques d’aménagement du territoire en Tunisie depuis quatre décennies environ, et sur le r le du déséquilibre régional dans le déclenchement de la révolution Tunisienne. Il soutient la nécessité actuelle de procéder, de manière concertée entre les différents acteurs, à une nouvelle lecture du territoire, tenant compte des résultats actuels et/ou attendus de la révolution, en vue de repenser les choix d’aménagement du territoire national. Through a retrospective approach, this paper attempts to provide a reflection on the evolution of landscaping policy in Tunisia over the last four decades, and the role of unequal regional development in the outbreak of the Tunisian revolution. It stresses the need, today, for the different stakeholders to engage in a concerted dialogue into a new reading of landscape, taking into account the current and/or the expected outcome of the Revolution in order to rethink the landscaping of the national territory.
Revisiting methicillin-resistant Staphylococcus aureus infections
Waness Abdelkarim
Journal of Global Infectious Diseases , 2010,
Abstract: Within less than 50 years, methicillin-resistant Staphylococcus aureus (MRSA) made a tremendous impact worldwide. It is not limited to medical facilities and healthcare institutions anymore. Indeed since two decades, cases of MRSA infections arising from the community among apparently healthy individuals are increasing. In this paper, I will present a case of community-associated MRSA sepsis followed by a comprehensive review about the history, pathogenesis, epidemiology, clinical presentations, diagnostic modalities, therapeutic options, contributing factors, growing cost and other pertinent elements of this newly evolving epidemic of MRSA infections.
Ethical concerns in early 21st century organ transplantation
Abdelkarim Waness
Journal of Medical Ethics and History of Medicine , 2011,
Abstract: Medical ethics is an indispensible and challenging aspect of clinical practice. This is particularly prominent in the field of organ transplantation. In this paper, initially, a clinical case with brain death that ended up as an organ donor will be presented. Following the presentation, important moral challenges which initially formed medical ethics and some highlights of it in organ transplantation will be discussed in detail. The impact of complex modern influential factors that might interfere with the practice of medical ethics in this field such as patients' vulnerability, financial temptations, and legal regulations will be also dealt with. Finally, we shall propose practical guidelines aiming at improving the practice of medical ethics in the emerging issue of organ transplantation.
Integration of Location-Allocation and Accessibility Models in GIS to Improve Urban Planning for Health Services in Al-Madinah Al-Munawwarah, Saudi Arabia  [PDF]

Journal of Geographic Information System (JGIS) , 2019, DOI: 10.4236/jgis.2019.116039
Abstract: In this study, accessibility and location-allocation models have been integrated into GIS to improve spatial planning and environmental sustainability of health services in Al-Madinah Al-Munawwarah. This integration provides a planning framework in order to check the efficiency of the spatial allocation of health services and to generate alternatives either by proposing an active service or to improve an existing one. To achieve these objectives, the accessibility to the service area was analyzed within the analysis of health services networks, which are divided into eight types: public hospitals, specialized hospitals, health units, healthcare centers, infirmaries, clinic complexes, the Red Crescent Center, and ambulance facilities, with time intervals of (5 minutes - 10 minutes - 15 minutes) to access coverage ranges, and the location-allocation model was used based on the maximum coverage model within a response time not exceeding 15 minutes, The results of the study revealed the poor distribution of health services Al-Madinah Al-Munawwarah suffers from weak accessibility to health services coverage areas and is unable to meet the needs of its population at present. The current need for health services reached twenty-four locations, including two public hospitals, three specialized hospitals, two health centers, three ambulance facilities, four infirmaries, three clinic complexes, four health units, and three Red Crescent centers.

Abstract: Many organizations in Jordan are currently frustrated with the benefit and value obtained from their investment in IT. An understanding of why Jordanian organizations do not benefit from IT investment can assist these organizations to explore the factors that organizations use to align IT with their business objectives. In-depth qualitative interviews with IT managers in Jordanian organizations suggest that leadership, structure and process, service quality and values and belief are the most important factors which are representative of the culture gap between IT strategy and business strategy. The lack of these factors hinders organizations from gaining benefits from their investment in IT. From the findings of this study, it is found that the alignment gap is often used to explain or justify an organization’s inability to effectively leverage on IT.
The substrate specificities of sunflower and soybean phospholipases D using transphosphatidylation reaction
Slim Abdelkafi, Abdelkarim Abousalham
Lipids in Health and Disease , 2011, DOI: 10.1186/1476-511x-10-196
Abstract: In this work, we have studied the substrate specificity of PLDs from germinating sunflower seeds and cultured-soybean cells, using their capacity of transphosphatidylation. In the presence of a nucleophilic acceptor, such as [14C]ethanol, PLD catalyzes the production of phosphatidyl-[14C]-ethanol. The resulting product is easily identified since it is well separated from the other lipids by thin-layer chromatography. The main advantage of this assay is that the phospholipid used as substrate does not need to be radiolabelled and thus allow us a large choice of polar heads and fatty acids. In vitro, we observed that sunflower and soybean cell PLD show the following decreasing order of specificity: phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol; while phosphatidylserine and phosphatidylinositol are utilized much less efficiently.The substrate specificity is modulated by the fatty acid composition of the phosphatidylcholine used as well as by the presence of other charged phospholipids.Phospholipase D (PLD) (phosphatidylcholine phosphatidohydrolase, [EC3.1.4.4]) is a ubiquitous enzyme present in mammals, plants and bacteria [1-3]. PLD catalyses two reactions (i) hydrolysis of phospholipids to produce phosphatidic acid (PA) and a free polar head group such as choline in the case of phosphatidylcholine (PC), and (ii) transphosphatidylation reaction which, in the presence of a primary alcohol, PLD leads to the formation of the corresponding phosphatidyl alcohol [3]. The latter product is less subject than PA to further metabolism, and can easily be separated from the substrate and other hydrolytic products by performing thin-layer chromatography (TLC). Transphosphatidylation is a useful reaction synthesizing natural phospholipids, such as phosphatidylserine (PS) and phosphatidylglycerol (PG), and novel artificial phospholipids [4]. These phospholipids have been used for pharmaceuticals, foods, cosmetics, and other industries. Transphosphatidylation
