Conducting Research with South African Survivors of Human Rights Violations: Some Considerations

Behavioural science research in a developing world context involves unique methodological and logistical challenges and requires cognisance of local sensitivities. This paper discusses the ethical, logistical, and methodological problems encountered during the conduct of a study with survivors of human rights violations in South Africa. Research practices such as subject recruitment, negotiating language and literacy, and other methodological concerns are considered in the context of post-apartheid South Africa. The legacy of the Truth and Reconciliation Commission is also addressed in terms of the manner in which it affects the conduct of research. Finally, the manner in which research into highly politicised traumatic events is affected by the South African social and historical context is examined and recommendations are offered for behavioural science research in developing countries.     

Brain type natriuretic peptide (BNP)—A marker of new millennium in diagnosis of congestive heart failure

The burden of disease in patients with congestive heart failure is high. The future of BNP looks promising as it may be a better diagnostic tool for the diagnosis of CHF in developing countries in new millennium. Natriuretic peptide hormones, a family of vasoactive peptides with many favourable physiological properties, have emerged as important contenders for development of diagnostic tools and therapeutic agents in cardiovascular disease. Measurement of B-type natriuretic peptide has become as an easy-to-perform bedside test. The clinical and diagnostic significance of the measurement of plasma Nt-proBNP in the diseases of the cardiovascular system with particular emphasis on the assessment of patients with heart failure and their effects on predicting survival rate. The plasma levels of Nt-proBrain Natriuretic peptide responds more vigorously after myocardial infarction than those of other natriuretic peptides. This article is an attempt to give a short overview on the utility of BNP-blood levels for the diagnosis and treatment of heart failure     

An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.     

Library Anxiety among Undergraduate Students: A Comparative Study on Egypt and Saudi Arabia

The purpose of this paper is to report the findings of a study of library anxiety among a group of Arab students in Saudi Arabia and Egypt. The paper also investigated the factors that affect the students' level of anxiety while using academic libraries. The study tried to compare the difference in the level of anxiety in the two countries using a scale (LLPB) developed by the researchers which fit the culture in the Arab region. The study adopted a mixed methods approach. Semi-structured interviews were conducted with several students in Saudi Arabia and Egypt to determine the main factors that lead to having a level of anxiety in the libraries. In the second stage, a questionnaire was sent to students to measure what factors have a greater impact on the level of anxiety. The data showed that Egyptian students are more anxious about using the libraries than the Saudi students. The results also indicated that there is a need to train students on how to use the libraries and also change students' perception regarding the library to reduce the level of anxiety. This study was conducted in Egypt and Saudi Arabia the level of library anxiety and the factors that may affect the students may vary in other countries.     

Hydraulic jump basins with wedge-shaped baffles

This laboratory study deals with the hydraulic jump properties for an artificially roughened bed with wedge-shaped baffle blocks. The experiments were conducted for both smooth and rough beds with a Froude number in the range of 3.06??F ₁??10.95 and a relative bed roughness ranging 0.22??K _R??1.4. The data from this study were compared with those of rectangular baffle blocks. New experimental formulae were developed for determining the sequent depth ratio and the hydraulic jump length in terms of the inflow Froude number and relative bed roughness. Bélanger??s jump equation of a rectangular channel was extended to account for the implications of the bed shear stress coefficient attributable to channel bed roughness. It was found that, in comparison with the smooth bed, the wedge-shaped bed roughness reduced the sequent depth of the hydraulic jump by approximately 16.5% to 30% and the hydraulic jump length by approximately 30% to 53%.     

Contextual influences on sources of academic self-efficacy: a validation with secondary school students of Kerala

This study investigates the theorized sources of Academic Self-Efficacy among the higher secondary school students of Kerala, India. Mastery Experience in the form of Academic Achievement, vicarious experience in the form of School Image and Social Persuasion in the form of Parental Encouragement are included as the predictor variables of Academic Self-Efficacy. Participants in the present study were 700 higher secondary school students of Kerala, selected using stratified random sampling. The findings of the study confirm the theorized correlation of Academic Self-Efficacy with previous achievement, vicarious experience (school image) and persuasory information (parental encouragement). In the total sample, the percent of variance in Academic Self-Efficacy that is predictable by the three-predictor variables is nearly one quarter (23.83?%). School Image is the best contributing variable (9.42?%) followed by Mastery Experience (8.67?%) and then by Parental Encouragement (5.74?%). The findings shows that apart from cultural differences, locale and gender difference also exist in sources of Academic Self-Efficacy. The superiority of School Image over Mastery Experience in predicting Academic Self-Efficacy is different from that found in the West, theoretically and empirically. In India, self-efficacy beliefs of youngsters continue to depend more on social and domestic factors than personal experience and mastery.     

An exploration of Naquib al-Attas’ theory of Islamic education as ta’dīb as an ‘indigenous’ educational philosophy

Abstract

This paper explores the ‘indigenous’ philosophy of education of Syed Muhammad Naquib al-Attas, a Malay-Muslim scholar who’s theoretical work culminated in the establishment of a counter-colonial higher education institution. Through presenting al-Attas’ life and philosophy and by exploring the arguments of his critics, I aim to shed light on the challenges and paradoxes faced by indigenous academics working at the interface of philosophy and education.
