An educational laboratory virtual instrumentation suite assisted experiment for studying fundamentals of series resistance–inductance–capacitance circuit

One of the most elementary concepts in freshmen Electrical Engineering subject comprises the Resistance–Inductance–Capacitance (RLC) circuit fundamentals, that is, their time and frequency domain responses. For a beginner, generally, it is difficult to understand and appreciate the step and the frequency responses, particularly the resonance. This paper proposes a student-friendly teaching and learning approach by inculcating the multifaceted versatile software LabVIEW^TM along with the educational laboratory virtual instrumentation suite hardware, for studying the RLC circuit time and frequency domain responses. The proposed approach has offered an interactive laboratory experiment where students can model circuits in simulation and hardware circuits on prototype board, and then compare their performances. The theoretical simulations and the obtained experimental data are found to be in very close agreement, thereby enhancing the conviction of students. Finally, the proposed methodology was also subjected to the assessment of learning outcomes based on student feedback, and an average score of 8.05 out of 10 with a standard deviation of 0.471 was received, indicating the overall satisfaction of the students.     

Blended Learning for Learner Empowerment: Voices from the Middle East

Blended learning (BL) is still in its infancy in the United Arab Emirates, but is gaining growing attention and acceptance. The particular university under investigation offers its nationally accredited graduate programs with a BL format that makes use of synchronous virtual classrooms, asynchronous self-study, and face-to-face sessions. The current qualitative research study investigates students' perceptions about their experience with the BL model within their relatively conservative cultural context. In addition, the project aimed at gauging their suggestions for course design considerations that would meet their needs as adult learners and enhance their learning experience. Twenty-one graduate students participated in the study, with findings indicating an overall positive perception about the BL experience with a strong positive impact on female empowerment. The most salient themes for successful instructional strategies indicated the importance of student-centered practices, particularly collaborative projects and student-led activities.     

Study of enzyme activities in the descending part of the duodenum in patients of duodenal ulcer

The aim of this study was to measure the levels of lactase, sucrase, maltase, leucine amino peptidase and gamma-glutamyl transpeptidase in duodenum of Indian patients with duodenal ulcer. The effect of duodenum inflammation on these brush border enzymes has also been analysed in this study. Levels of lactase, sucrase, maltase, leucine amino peptidase and gamma-glutamyl transpeptidase were assessed in duodenal biopsies of 20 patients of duodenal ulcer and 20 non-ulcer dyspepsia. The duodenal biopsy specimens were also examined histopathologically for presence or absence of inflammation. There was no significant difference (p>0.05) in the activity of above mentioned enzyme levels in both the groups. Only levels of gamma-glutamyl transpeptidase were significantly decreased in patients of duodenal ulcer with duodenal inflammation. This study shows that only the levels of gamma-glutamyl transpeptidase were significantly decreased in patients of duodenal ulcer with inflammation but no change in duodenal enzymes due to duodenal ulcer as compared to non-ulcer dyspepsia.     

Gender,teaching and academic promotions in higher education

Teaching is increasingly being considered for inclusion in academic promotions in a number of universities. This raises questions about how teaching is appraised in relation to research; and which teaching criteria contribute to promotions outcomes. This article investigates these questions from a gender perspective by statistically analysing the actual promotions outcomes by rank levels at a South African university where teaching and research have been equally evaluated in academic promotions. The findings show that, overall, there was no statistically significant difference in promotions success rates between males and females and that more females achieved excellence in teaching with higher scores than males. Two of the 10 teaching criteria analysed – ‘ongoing study of tertiary education’ and ‘special recognition of teaching’ showed statistically significantly higher scores for females with high effect sizes, pointing to the importance of the Scholarship of Teaching and Learning in academic promotions for women. This study has implications for closing the gender gap in the senior ranks of universities.     

Antral and duodenal disaccharidases in patients of duodenal ulcer and non-ulcer dyspepsia

Duodenal ulcer is a common disease and is considered acid-peptic disease. Duodenal ulcer patients are known to have higher incidence of antral gastritis and duodentitis than general population. Thus one can expect some alteration in the enzyme products of mucosal cells of antrum and duodenum in this condition. The present study was planned in 30 patients of duodenal ulcer and 30 of non-ulcer dyspepsia. After overnight fast, upper gastrointestinal endoscopy was done using forward viewing fibreoptic endoscope. Two pairs of biopsies were taken from the antrum and two from the descending duodenum using standard biopsy forceps. One pair of biopsy from each site was taken in 10% formal saline for histopathological examination. One pair of biopsies from each site was collected in saline for the measurement of disaccharidases by Dahlquist method. Activities of lactase, sucrase and maltase were significantly higher in descending duodenum mucosa as compared to antral mucosa in both groups. Activities of these enzymes in antrum and duodenum of both groups did not differ significantly. No significant difference was found in disaccharidases in antrum and descending duodenum in patients with or without histological gastritis. This study suggests that the disaccharidases do not change in antrum and duodenum of ulcer patients as compared to the patients with non-ulcer dyspepsia.     

Perceptions of police-civilian encounters: Intergroup and communication dimensions in the United Arab Emirates and the USA

This study investigates the impact of perceived police accommodation on police–civilian interactions. Elaborating theoretically beyond a range of cross-cultural studies, we examine the cultural impact of accommodative communication in the United Arab Emirates and the USA, as the prior context demonstrates sociocultural parallels and differences including the influence of Sharia law. Between-country comparisons evaluate the mediating role of trust, affect, and intergroup orientation on various civic outcomes. Accommodative communication was the strongest predictor of trust for both nations and demonstrated a direct impact on moral alignment and willingness to help only in the United Arab Emirates.     

Evaluation of Flow Rate,pH, Buffering Capacity,Calcium, Total Proteins and Total Antioxidant Capacity Levels of Saliva in Caries Free and Caries Active Children: An In Vivo Study

The purpose of this study was to evaluate the relationship between the physicochemical properties of saliva such as flow rate, pH, buffering capacity, calcium level, total protein and total antioxidant levels in caries free and caries active children. The present study included one hundred and twenty healthy children who were divided into two groups; group I and group II comprising of age groups 7–10 and 11–14 years, respectively. Both the groups were then sub-divided equally according to gender. They were further divided into caries free and caries active with 15 children in each group. Unstimulated saliva was collected by suction method and flow rates were determined. The samples were then analyzed for pH, buffering capacity, total protein, calcium and total antioxidant capacity. The data was statistically analyzed using student t test (unpaired). The results revealed that when all these parameters were compared among the caries free and caries active children, flow rate, pH, buffering capacity were slightly reduced in caries active children, but total protein and total antioxidant capacity of saliva increased significantly in caries active children and the total calcium decreased significantly in caries active children. Within the limitation of this study, we conclude that, the physicochemical properties of saliva play a major role in the development of caries.     

Resource endowments and responses to regulatory pressure: Publications of economics, management, and political science departments of Turkish universities in indexed journals, 2000–2008

This paper investigates how differences in resource endowments of universities shape variation in their response to regulatory pressures. Earlier research on higher education institutions tends to conceive regulatory rules as the primary basis of action and does not attend to differences in the salient characteristics of universities. This paper is based on the premise that satisfying regulatory demands requires resources that are compatible with these demands, making resource endowments of universities a potentially significant source of variation in their responses to regulatory pressures. We empirically investigate the relationship between human resource characteristics of economics, management, and political science departments of Turkish universities and how these departments responded to the intensifying regulatory pressure to publish more in indexed journals. Findings reveal that departments which predominantly employ researchers trained in North American universities published significantly more in indexed journals between 2000 and 2008. These departments are better endowed with respect to resources that are necessary for publishing in indexed journals, most importantly knowledge of theory, methodology, and style sought by indexed journals. The paper shows that attending to differences in resource endowments of universities as well as regulatory goals and tools facilitates understanding of how regulation-driven processes unfold.     

Jordanian School Counselors’ Leadership Behaviors

The purpose of this study was to identify the degree to which Jordanian school counselors were seen by teachers and principals to possess and display leadership behaviors related to Bolman and Deal’s (1997) transformational ‘four framework approach’ to leadership. This was based on the view that such leadership would relate to counselors’ effectiveness in their roles. A questionnaire was administered to a sample of teachers and principals designed to assess counselor leadership on four key dimensions (i) structural leadership, (ii) human resources leadership, (iii) political leadership, and (iv) symbolic leadership. The results of the study suggest high levels of transformational leadership among Jordanian school counselors as perceived by both teachers and principals. Principals assessed the levels more highly than teachers, with a significant difference evident. The results also showed a significant difference based on geographic area of the participants, even though those from all areas rated counselor leadership quite highly.     

Reading social stories in the community: A promising intervention for promoting children's environmental knowledge and behavior in Jordan

Traditionally, education in various forms has been used as a tool to change values and behavior in children regarding the environment. This study reports findings from the We Love Reading Program that utilizes the reading of Social Stories in various communities in Jordan to address the environmental problems of Jordan. Results indicated the effectiveness of this informal educational intervention showing a significant increase in children's knowledge about environmental issues and a positive change in behavior related to electricity and water consumption and littering, as reported by parents. The authors provide several recommendations on how Social Stories and appropriate curriculum can be used in schools and community to create awareness in students regarding environmental issues.
