Antidyslipidemic and Antioxidant Activities of Hibiscus rosa sinensis Root Extract in Alloxan Induced Diabetic Rats

The antidyslipidemic activity of Hibiscus rosa sinensis (Malvaceae) root extract has been studied in alloxan induced diabetic rats. In this model, oral administration of root extract (500 mg/kg bw. p.o.) for 15 days resulted in significant decreased in the levels of blood glucose, plasma lipids and reactivated post heparin lipoprotein lipase activity in alloxan induced diabetic rats. Furthermore, the root extract (50–500 μg) when tested for its antioxidant activity, inhibited the generation of super oxide anions and hydroxyl radicals, in both enzymic and non enzymic systems in vitro. The results of the present study demonstrated antidyslipidemic and antioxidant activities in root extract of H. rosa sinensis which could be used in prevention of diabetic-dyslipidemia and related complications.     

Circadian Rhythm of Serum Cortisol in Female Patients with Fibromyalgia Syndrome

Fibromyalgia syndrome (FMS) patients have disturbed sleep patterns which may lead to altered circadian rhythm in serum cortisol secretion. The aim of this study was to assess circadian changes, if any, in serum cortisol levels in female patients with FMS. Cortisol levels were estimated every 6 h during 24 h period; in 40 female patients satisfying ACR criteria for FMS (Age 36.4 ± 9.9), and 40 healthy females without FMS (Age 33.8 ± 11.1). A significant difference in the night time serum cortisol level was observed among the patients and control groups (patients, 12.9 ± 9.7 controls 5.8 ± 3.0; p < 0.01). However, no significant difference was found in serum cortisol levels in patients and control groups in the morning (patients, 28.4 ± 13.2 controls, 27.6 ± 14.5; p > 0.05), afternoon (patients, 14.4 ± 5.6 controls, 14.0 ± 6.6; p > 0.05) and evening hours (patients, 10.9 ± 5.8 controls, 8.9 ± 3.6; p > 0.05). It could be concluded that there is an abnormality in circadian secretion of cortisol in female FMS patients.     

THE EFFECT OF COOPERATIVE LEARNING STRATEGIES ON ELEMENTARY STUDENTS’ SCIENCE ACHIEVEMENT AND SOCIAL SKILLS IN KUWAIT

This study compares the effects of two methods of teaching—teacher-centered and cooperative learning—on students’ science achievement and use of social skills. The sample consists of 163 female elementary science students in 8 intact grade 5 classes who were assigned to 2 instructional methods and were taught an identical science unit by 4 classroom teachers. The students’ science achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest. Students’ social skills were determined by a researcher-designed survey administered as a pretest and posttest. Analysis of the achievement test scores and the social skills survey responses revealed that cooperative learning strategies have significantly (p > 0.05) more positive effects on both students’ achievement and social skills than teacher-centered strategies. These results provide an evidential base to inform policy decisions and encourage and persuade teachers to implement cooperative learning methods in Kuwaiti classrooms.     

English language teaching reform in Sultanate of Oman: The case of theory and practice disparity

Sultanate of Oman is one out of many developing countries around the world which have valued English as a very important international language and a tool for achieving multiple purposes. When His Majesty the Sultan came to power in 1970, the government accepted English as the only official foreign language and allocated huge budgets and resources for its implementation through education. However, almost three decades after this, it was found that students exiting the ELT system in Oman suffer from various inadequacies in their English language proficiency, which has had negative implications for Oman??s national development. This has driven the government to attempt to revolutionize English language teaching (ELT) through pursuing a reform plan??Basic Education System (BES). This paper attempts to examine the attitudes of 141 freshmen, who have exited the BES and joined Sultan Qaboos University (SQU) in September 2009, about their teachers and the curriculum. The results have shown that there have hardly been any significant changes in the BES reform project, as compared to the previously implemented system??General Education System (GES) mainly due to implementation shortcomings.     

The development of young children of immigrants in australia, Canada, the United kingdom, and the United States

In spite of important differences in some of the resources immigrant parents have to invest in their children, and in immigrant selection rules and settlement policies, there are significant similarities in the relative positions of 4- and 5-year-old children of immigrants in Australia, Canada, the United Kingdom, and the United States. Children of immigrants underperform their counterparts with native-born parents in vocabulary tests, particularly if a language other than the official language is spoken at home, but are not generally disadvantaged in nonverbal cognitive domains, nor are there notable behavioral differences. These findings suggest that the cross-country differences in cognitive outcomes during the teen years documented in the existing literature are much less evident during the early years.     

Extended structural relevance framework: a framework for evaluating structured document retrieval

A structured document retrieval (SDR) system aims to minimize the effort users spend to locate relevant information by retrieving parts of documents. To evaluate the range of SDR tasks, from element to passage to tree retrieval, numerous task-specific measures have been proposed. This has resulted in SDR evaluation measures that cannot easily be compared with respect to each other and across tasks. In previous work, we defined the SDR task of tree retrieval where passage and element are special cases. In this paper, we look in greater detail into tree retrieval to identify the main components of SDR evaluation: relevance, navigation, and redundancy. Our goal is to evaluate SDR within a single probabilistic framework based on these components. This framework, called Extended Structural Relevance (ESR), calculates user expected gain in relevant information depending on whether it is seen via hits (relevant results retrieved), unseen via misses (relevant results not retrieved), or possibly seen via near-misses (relevant results accessed via navigation). We use these expectations as parameters to formulate evaluation measures for tree retrieval. We then demonstrate how existing task-specific measures, if viewed as tree retrieval, can be formulated, computed and compared using our framework. Finally, we experimentally validate ESR across a range of SDR tasks.     

Teachers’ perceptions of the concomitance of emotional behavioural difficulties and learning disabilities in children referred for learning disabilities in Oman

Research has documented overlapping and coexisting characteristics of learning disabilities (LD) and emotional and behavioural difficulties (EBD). Such concomitance may impact teacher referrals of children at risk for LD which in turn may influence service delivery. Using the Learning Disabilities Diagnostic Inventory (LDDI) and the Strengths and Difficulties Questionnaire (SDQ), we examined teachers’ ratings of EBD and LD symptoms in 439 students referred for LD in elementary schools in Oman. A multivariate analysis of variance (MANOVA) showed that there were no gender differences in LD symptoms, whereas there were significant gender differences in teachers’ ratings of hyperactivity and conduct problems in referred children. There was an association between teachers’ ratings on the LDDI and SDQ dimensions, reflecting children’s concurrent display of LD and EBD symptoms. Implications are discussed within an Omani context in which there is a need to increase teachers’ awareness of the behavioural and emotional profile of children at risk for LD.     

Information Technology for Economic and Social Benefit—Options for Bangladesh

Significant changes in the Indonesian political system have affected most aspects of its government and community. First, there is an effort to implement democracy in terms of ideology as well as political practices. Second, the government system is transforming from centralization to decentralization, as the development process is delegated to regional governments (cities and kabupatens). Third, there is an effort to build community consciousness through community participation in national and regional development.

Participating in the development process, citizens should be supported with relevant public information. It is the government's task to provide information regarding governmental issues and public interests. As communication and information have been delegated to regional governments, they should execute this task based on good governance principles.

However, providing fair and balanced information is not simple. Large populations and regions separated by water and mountains make the task harder. Therefore, regional governments must adopt advanced information technology systems, which functioned to transfer information to the public as well as to receive public feedback medium in an efficient and effective way. To meet those qualifications, regional governments endeavor to implement e-government as a tool for democratizing communication and information.

After almost 3 years, there are indications that e-government has not been properly implemented by regional governments. They have faced many problems, including lack of financing, poor technical skill, lack of human resources and infrastructure, and the political will of the government elite itself.

Nevertheless, there are many ways to overcome these problems. Standardizing the application of e-government, establishing the regulation of e-government, involving other stakeholders, and developing human resources may aid in the implementation of e-government. In addition, lessons learned from other regions, for example, Kutai Timur or Gorontalo, are also recommended.     

Cyber Bullying @ Schools: What do Turkish Adolescents Think?

Cyber bullying is an emerging form of peer bullying, becoming prominent especially over the past decade. The aim of this study was to investigate through interviews the perceptions of Turkish high school students about cyber bullying. The sample consisted of six male and one female high school students all aged 15 years who identified as being active in cyber bullying. Findings were grouped under four main headings; acts of cyber bullying, reasons for cyber bullying, characteristics of cyber bullies and victims, and suggestions to prevent cyber bullying. The results were discussed in the light of relevant literature.     

The role of extracurricular activities in active citizenship education

There have been multiple trends of building democratic citizens through formal education, and in the European context the trials have been dramatically increased with the Europeanization process since the 1980s. In line with this trend, an in-depth qualitative case study was carried out in a private primary school in Turkey to shed light on the role of school-based extra-curricular activities as a contemporary trend in building active citizenship values and competencies in students. Qualitative data were collected through multiple data collection tools as observation field notes, interviews, and document analysis to achieve triangulation and trustworthiness. Much of the findings were compatible with EURYDICE Report (2005) on citizenship education, and yielded six themes, called the six blossoms of extra-curricular activities in citizenship education: namely, active citizenship perception; social accountability; intercultural awareness; awareness of democracy and human rights; thinking and research skills; and interaction and interpersonal skills.
