This paper presents a continuous work related to the status and engagement with e-learning systems by faculty members in Jordanian universities. Previous research study entitled (Evaluating E-Learning System Use by CBAM-Stages of Concern Methodology in Jordanian Universities, 2015) focused on defining stages of concern using one tool that is presented by CBAM Framework. The CBAM Framework provides another tool that is used specifically for measuring level of use of any educational technology. This research focused on using CBAM framework for the first time in Jordanian Higher educational context in order to present a systematic and well-defined methodology for evaluation that will be used for defining the exact engagement with elearning. It is believed that the results of this research can be reflected positively on universities future policies and practices for developing the use of this educational technology in Jordan.

This paper is attempting in terms of a formal statistical language model to review the overall domination of Arabic morphology as a non-linear or non-concatenated processing system in the case of word identification. The basic components of this model are relying on bi-directional probabilistic root-pattern relationships acting as cognitive morphological factors for word recognition. Considering a root in the mental lexicon as the highest level of semantic abstraction for a morpheme allows the view of considering words as a functional or applicative process instantiating the most probable or known pattern to the most plausible root. As Arabic is known for its highly inflectional morphological structure and its high tendency to pattern and root ambiguity (Root-Homonymy and Pattern Polysemy) this model is assuming bi-directional morphological background knowledge for resolving ambiguities in form of probabilistic semantic network. As a major consequence, this paper is stressing the significance of this phenomenon in designing Arabic interactive cognitive systems particularly those related to interactive Arabic natural language understanding and word recognition and corrections. © 2012 IEEE.

The aims of this work were to study pharmacokinetics of randomly selected drugs in plasma and saliva samples in healthy human volunteers, and to introduce a Salivary Excretion Classification System. Saliva and plasma samples were collected for 3-5 half-life values of sitagliptin, cinacalcet, metformin, montelukast, tolterodine, hydrochlorothiazide (HCT), lornoxicam, azithromycin, diacerhein, rosuvastatin, cloxacillin, losartan and tamsulosin after oral dosing. Saliva and plasma pharmacokinetic parameters were calculated by noncompartmental analysis using the Kinetica program. Effective intestinal permeability (Peff) values were estimated by the Nelder-Mead algorithm of the Parameter Estimation module using the SimCYP program. P eff values were optimized to predict the actual average plasma profile of each drug. All other physicochemical factors were kept constant during the minimization processes. Sitagliptin, cinacalcet, metformin, tolterodine, HCT, azithromycin, rosuvastatin and cloxacillin had salivary excretion with correlation coefficients of 0.59-0.99 between saliva and plasma concentrations. On the other hand, montelukast, lornoxicam, diacerhein, losartan and tamsulosin showed no salivary excretion. Estimated Peff ranged 0.16-44.16 × 10-4 cm/s, while reported fraction unbound to plasma proteins (fu) ranged 0.01-0.99 for the drugs under investigation. Saliva/plasma concentrations ratios ranged 0.11-13.4, in agreement with drug protein binding and permeability. A Salivary Excretion Classification System (SECS) was suggested based on drug high (H)/low (L) permeability and high (H)/low (L) fraction unbound to plasma proteins, which classifies drugs into 4 classes. Drugs that fall into class I (H/H), II (L/H) or III (H/L) are subjected to salivary excretion, while those falling into class IV (L/L) are not. Additional data from literature was also analyzed, and all results were in agreement with the suggested SECS. Moreover, a polynomial relationship with correlation coefficient of 0.99 is obtained between S* and C*, where S* and C* are saliva and concentration dimensionless numbers respectively. The proposed Salivary Excretion Classification System (SECS) can be used as a guide for drug salivary excretion. Future work is planned to test these initial findings, and demonstrate SECS robustness across a range of carefully selected (based on physicochemical properties) drugs that fall into classes I, II or III. © 2012 American Chemical Society.

Motivated by the nature of Arabic and encouraged by the delivered indications by psycho-cognitive research in retrieval of linguistic constituents of a word, a statistical language model for Arabic based on Associative Probabilistic bi-directional Root-PATtern relations", (A-APRoPAT) was formalized. The basic components of this model are relying on bi-directional probabilistic root-pattern relationships acting as cognitive morphological factors for word recognition in addition to semantic classes capturing textual and contextual root associative network. Considering a root in the mental representation as the highest level of symbolic semantic abstraction for a morphological unit allows the perception of words as a probabilistic applicative process instantiating the most plausible or known pattern to the most conceivable root, in an Associative Root-Pattern Network. As Arabic is known for its highly inflectional morphological structure and its high tendency to pattern and root ambiguity (Pattern Polysemy and Root-Homonymy) this model is assuming bi-directional morphological background knowledge for resolving ambiguities in the form of a probabilistic semantic network. As a major consequence, this paper is stressing the significance of this phenomenon in designing Artificial Cognitive Systems and Cognitive Infocommunications Applications concerned with Arabic interactive systems particularly those related to Arabic natural language understanding and human visual word identification and corrections besides the overall domination of Arabic morphology as a non-linear or non-concatenated processing system in the case of word identification.

Many studies have reported the utilization of Problem-Based Learning (PBL) in teaching Software Engineering courses. However, these studies have different views of the effectiveness of PBL. This paper presents the design of an Advanced Software Engineering course for undergraduate Software Engineering students that uses PBL to teach them Agile software development methods- particularly Scrum. The course also aims to develop entrepreneurial skills needed for software engineering graduates to better prepare them for the software industry. The assessment process designed for this course is illustrated. The paper shows that Scrum practices correlate with the characteristics of the PBL approach, which has resulted in a successful experience of PBL as reported by students in an end of a semester survey.

The objective of this paper is to investigate one aspect of the challenges of participatory planning and development in the Jordanian context focussing on the case of refugee camp-cities. These enclaves of quasi squatter-formal settlements provide valuable insights into the complex and multifaceted process of participation in Jordan. The challenges of urban development within the camps' high-density sub-standard environment are augmented by the lack of clear vision due to the complexity of the regional and international political context. Within this framework, an amalgamation of variables impact attempts towards a transparent and inclusive development project.The paper investigates an innovative participatory project for slums upgrading that was designed to engage the local community in its leadership and decision-making. The project adopted the principles of Good Governance and fostered social inclusion and transparency. As such, this case study offers a rare opportunity to investigate a participatory project that is true to the principles of participation and empowerment within a context that is inexperienced in such approaches. The objective of the paper is to understand the locals' response to a new kind of project that is based on inclusiveness, transparency, and equity.The enquiry shows that local power structures will resist such a project's approach because local elites view themselves as gatekeepers to the community. Different tactics will be used towards controlling the project's decision-making process or thwarting approved projects. The process is highly dynamic as actors change positions and yesterday's allies are tomorrow's foes. Local actors play a variety of roles and they ruminate the culture of exclusion and domination. The Talbiyeh Camp Improvement project represents a case study for democratisation on the micro level and the dynamics of the process indicates that although hailed as a need by locals, a fair transparent process will face serious challenges in a context that is lacking in democratic examples and has layers of non-democratic political and social realities. Time and Authority are important variables for the success of such interventions. © 2013 Elsevier Ltd.

Recognizing the importance of culture in translation, this article presents a descriptive study of translation of literary texts from English into Arabic. Using the data taken from works of Shakespeare and others which were translated by eminent translators, it first describes the study background, research contexts and procedures and problems. It then addresses some research questions on: (1) Will the translation be accepted by the new community of readers; 2) Is the relation between culture and translation important? It is worth noting that this study is significant for translators and readers of the target language, which is Arabic in this case. This has been substantiated by surveying the interests in cultural aspects of translation as early as the 19th Century. Thus translations do not only include lexical content and syntax, but also ideologies, values and ways of life in a given culture, which form translating problems. Therefore, translators have to know the audience. © Australian International Academic Centre, Australia.

Nineteen raw vegetable crops were collected from major markets in Baghdad areas uncontaminated by human activities other than normal agricultural practice. Six hundred samples were prepared and analyzed under carefully controlled conditions for cadmium, lead, iron, copper and Zinc. The Levels of these Heavy Metals in the vegetables were relatively low with respect to the proposed maximum acceptable concentrations for human consumption. In lettuce, spinach and parsley relatively high level of lead and cadmium were noticed compared with tomato, eggplant and onion. Iron was the only element that showed statistical variation among the different of vegetables. © Asian Network for Scientific Information, 2010.

Multiple innate and adaptive immune effector cells and molecules partake in the recognition and destruction of cancer cells to protect against growing tumors, a concept that is known as cancer immunosurveillance. Unfortunately, cancer cells are capable of avoiding this process by immunoselection of poorly immunogenic tumor cells variants along with subversion of the immune system and thus shaping both the tumor and its microenvironment. Cytokines represent part of the complex pattern of the immune response which can assist the development of cancer as well as to eliminate it. Simultaneously, a large number of cytokines may be involved in the complex interactions between host and tumor cells where this dynamic cross-talk, between tumors and the immune system, can either regulate tumor growth or tumor growth, invasion and metastasis take place. In this review, we are stressing on the interface between infiltrated immune cells and tumor cells with the emphasis on the bidirectional activities of specific cytokines: IFN-γ, TGF-β and IL-17 within the tumor microenvironment and their role in shaping it. In addition, the significance of modulating such cytokines in favor of anti-tumor response is discussed and merits the use of mixture of targeted modulators to overcome the network complexity of cytokines in the tumor microenvironment. © 2011 Alshaker and Matalka; licensee BioMed Central Ltd.
