A new pedagogical design for geo-informatics courses using an e-training support system

The current study seeks to introduce a new pedagogical design for geo-informatics courses using an e-training support system. Laurillard’s conversational approach based on conceptual representation for both instructor and learner was used to form the framework. As the current study specifically interested in training as a special form for learning, so, we sought methods and strategies to integrate requirements of both company and employee into the design of training programs. Therefore, a competency perspective was adopted into the conversational framework to use learning design that leads to learning activities tightly related to the needs of the company and employee. The above framework has been developed with special consideration to the underpinning pedagogical principles and the needs of lifelong learning that continues after the training has been completed. The implementation of the developed framework needs a special computerized system, so an e-training support system (ETSS) was developed to realize the framework. ETSS is an open source and standard-based infrastructure to enable and foster competence development and exchange of learning activities and learning units. Although the domain of the current study focuses on geo-informatics, ETSS is applicable to any other domain. The developed framework through its ETSS implementation were evaluated in a typical training environment. The results indicated that the best method in training was the training with the developed system with 91.5 % in comparison with the traditional training method with 81.4 %.

Expansion of special education and promotion of inclusive education in China: conflict or cooperation? Stakeholders' views

A key objective of inclusive education is to provide learners with special educational needs with an environment that fosters a sense of belonging. They lose the sense of belonging when they feel being separated from the rest of society. Segregation is, however, a logically necessary method and means of the pursuit of inclusion. The focus of this study was to uncover the experiences and views of Chinese stakeholders regarding the possible conflict between expansion of special education (i.e., segregation, exclusion) and promotion of inclusive education (i.e., inclusion, mainstreaming). We conducted in-depth interviews with nine academics, administrators, and practitioners to better understand the possible impact of inclusive education on regular education. The main finding is that special education can be provided in four forms which the participants argued is an advantage to meet the needs of all learners. They argued that giving home education for learners with high severity, attending special education schools and mainstreaming schools are rehabilitation methods to prepare learners for full integration should they prove successful. The study contributes to a broader understanding of how special education is provided in China and its potential effects on regular education (e.g., challenges in teacher preparation, lack of resources).     

Serving our colleagues: reference and history of medicine services from the National Library of Medicine

Most biomedical librarians are frequent users of the major online services provided by the National Library of Medicine (NLM), part of the National Institutes of Health in Bethesda, Maryland. These services include MEDLINE/PubMed, MedlinePlus, ClinicalTrials.gov, PubMed Central, document delivery, and other key biomedical resources. This article highlights less well-known services from reference, to historical information, to training and other services which librarians may not be aware the NLM offers to them. NLM encourages librarians to consider that NLM's unique and unsurpassed collection can help when local resources may be too limited to serve the needs of their patrons. doi:10.1300/J115v26n01_07.     

Exploring the scholarly communication styles of Arab social science and humanities scholars

The purpose of this paper is to report the findings of a study of scholarly communication behaviour among Arab scholars. The main objective of this study is to determine how Egyptian and Saudi Arabian social sciences and humanities scholars engage in scholarly communication practices. The study used a mixed‐methods approach. A questionnaire was answered by a sample of 104 participants, followed by interviews with 36 participants to gain insight into the scholarly communication behaviour of the Arab scholars. The analysis demonstrated that participants use different styles of scholarly communication approaches. Most of the participants do use informal (social media) channels to communicate their research findings (particularly ResearchGate and Facebook), although priority is given to formal over informal publication in peer reviewed journals. Responses showed that the promotional systems of both countries dictate publication choices of scholars, reducing the amount of collaboration by ranking co‐publications lower than sole publications and favouring printed journals over online‐only journals.     

The Relation of Knowledge-Text Integration Processes and Reading Comprehension in 7th- to 12th-Grade Students

The integration of knowledge during reading was tested in 1,109 secondary school students. Reading times for the second sentence in a pair (Jane’s headache went away) were compared in conditions where the first sentence was either causally or temporally related to the first sentence (Jane took an aspirin vs. Jane looked for an aspirin). Mixed-effects explanatory item response models revealed that at higher comprehension levels, sentences were read more quickly in the causal condition. There were no condition-related reading time differences at lower comprehension levels. This interaction held with comprehension- and inference-related factors (working memory, word and world knowledge, and word reading efficiency) in the models. Less skilled comprehenders have difficulty in knowledge-text integration processes that facilitate sentence processing during reading.     

Why students leave engineering and built environment programmes when they are academically eligible to continue

The retention of students to graduation is a concern for most higher education institutions. This article seeks to understand why engineering and built environment students fail to continue their degree programmes despite being academically eligible to do so. The sample comprised 275 students registered between 2006 and 2011 in a faculty of engineering and the built environment, who were academically eligible to continue, but failed to register for their studies the following academic year. The sociological notions of structure and agency were used to make sense of the data. The findings suggest that some students had control over their decision to leave and some students’ decisions were dominated by various structural factors. The outcome of the study is helpful in terms of suggesting what actions can be taken in order reduce the number of students leaving in good academic standing.     

Does Melatonin Ameliorate Neurological Changes Associated With Alzheimer’s Disease in Ovariectomized Rat Model?

This study aimed to elucidate the mechanisms of melatonin to manage neurological damage in Alzheimer’s disease (AD) induced in ovariectomized rats. Forty adult female rats were enrolled in our study and were classified as; gonad intact control, ovariectomized control group, ovariectomized rats received melatonin, ovariectomized rats injected with AlCl₃ to induce AD and AD-induced rats treated with melatonin. Hydrogen peroxide (H₂O₂), malondialdehyde (MDA), total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), B cell lymphoma 2 (Bcl-2), brain derived neurotrophic factor (BDNF), acetylcholinesterase (AchE) and acetylcholine (Ach) were estimated in the brain tissues of the different groups. Treatment of AD-induced rats with melatonin produced marked improvement in the most studied biomarkers which was confirmed by histological investigation of the brain. In Conclusion, melatonin significantly ameliorates the neurodegeneration characteristic of AD in experimental animal model due to its antioxidant, antiapoptotic, neurotrophic and anti-amyloidogenic activities.     

Correlation and Multiple Regression Analyses of Pituitary Growth Hormone and Hepatic Activities in Hepatitis C Infection and Interferon Response

The prevalence of hepatitis C virus (HCV) infection varies across the world, with the highest percent of infections reported in Middle East, increasingly in Egypt. The current study aimed at examining the bio-statistical correlation and multiple regression analyses of pituitary growth hormone (GH) and liver activities among HCV genotype-4 patients treated with PEG-IFN-α plus RBV therapy. Herein, the current study was conducted on 100 HCV genotype-4 infected patients and 50 healthy controls. Patients received PEG-IFN-α/RBV for 24 weeks. Host RNA was isolated from patients’ sera for HCV genotyping and viral load determination. Moreover, the enzymatic activities of the liver, AFP, GH, PT, and CBC were performed in all volunteers. The present study resulted that the activities of the hepatic enzymes among HCV genotype-4 patients correlated together significantly. While, human GH showed a significant positive regression with pre-treatment ALT concentration in responders. Furthermore, multiple regression analysis for GH showed a significant positive correlation with pre-treatment ALT in HCV genotype-4 infected patients. We concluded that there were a putative significant relation between GH and pre-treatment ALT activity in HCV infection and response to IFN-based therapy.
