Establishment of engineering laboratories for undergraduate and postgraduate studies

The importance of the laboratories for the study of engineering problems is manifold. At the undergraduate level it provides an opportunity for the students to get an impression of the basic principles of engineering. At the postgraduate level it becomes an instrument for advanced level study and for the solutions to real-life engineering problems. Level of emphasis by an individual engineering institution on basic engineering, interdisciplinary aspects of engineering and relevance to international, national and local industrial trends effects the policy to establish the engineering laboratories. However, a core facility, for the teaching of the most basic principals of relevant field of engineering should be a common feature of all the laboratories associated with individual subject area. In this research paper an approach for establishing engineering laboratories is presented. It discusses the relation between the syllabus of appropriate level of study and the equipment required in the laboratory, physical planning for the laboratory, sequential and parallel approaches for establishing the laboratories, the functional capacity of laboratories, the organizational flexibility of the laboratories, the cost factor and the recurring expenditure. It suggests ways of utilizing the laboratory for effective teaching and research through optimal use of the above factors.     

Developing the Inner Scientist: Book Club Participation and The Nature of Science

The leap from science student to scientist involves recognizing that science is a tentative, evolving body of knowledge that is socially constructed and culturally influenced; this is known as The Nature of Science (NOS). The aim of this study was to document NOS growth in first-year premedical students who participated in a science book club as a curricular option. The club read three acclaimed nonfiction works that connect biology to medicine via the history of scientific ideas. Students’ NOS status was assessed as informed, transitional, or naïve at the beginning and end of the academic year using the Views of Nature of Science Questionnaire–Form C (VNOS-C). Focus group interviews and document analysis of assignments and exams provided qualitative evidence. VNOS-C scores improved over the academic year regardless of book club participation. Students who participated in book club had marginally better NOS status at the end of the year but also at the beginning, suggesting that book club may have attracted rather than produced students with higher NOS status. It is notable that an improvement in NOS understanding could be detected at all, as there have been few reports of NOS growth in the literature in which NOS was not an explicit topic of instruction.     

Robust cooperative control for a group of mobile robots with quantized information exchange

In this paper we investigate the cooperative tracking control problem with quantized time delay information exchange for a group of wheeled mobile robots networked through a connected graph modeling the underlying communication topology. A cooperative controller is proposed using a combination of backstepping technique, graph theory and neural network radial basis functions. We show, using the small gain theorem, that the states of each mobile robot in the group converge to and remain inside a tube centered around its assigned trajectory to form a desired geometric pattern whose centroid is assumed to move along a predefined trajectory. Experimental results on a group of three mobile robots forming a triangular shape are presented to demonstrate the good performance of the proposed cooperative controller.     

Provision of public educational services and access to higher education among the Negev Bedouin Arabs in Israel

This paper deals with the provision of educational services and access to higher education of the Negev Bedouin Arabs in Israel, in the context of the social change this community is undergoing. The Negev Bedouin have been transformed from semi‐nomads and agriculturists to urban town dwellers. Education in general, and higher education in particular, are crucial to their adjustment and development. As members of the Arab minority in Israel, they face a number of inequities in the provision of educational services, access to higher education and access to job opportunities. The Negev Bedouin schools face additional problems related to the lack of qualified teachers and proper facilities. These schools have the highest drop‐out rates and the poorest success rates on the matriculation exams in the country. As of the 1993‐94 academic year, there were only 135 Bedouin Arab university graduates and 163 university students. Their higher education ratio is 2 per 1000, which is far below the Israeli national average of 80 per 1000. Recommendations are offered for improving the access of Negev Bedouin Arabs to higher education and their subsequent absorption into the Israeli labour market.     

Opening Up Alternatives to Dominant Ideological Constructions of English Language Teaching in Malaysia

ABSTRACT

This paper investigates the impact of the Common European Framework of Reference for Languages (CEFR) on the way English language teaching (ELT) is currently understood and practised in Malaysia. It presents a critical discourse analysis of newspaper texts in order to show how CEFR represents a form of Western-imposed globalisation that conflicts with local cultures and values. We argue that the newspapers construct a dominant discourse that promotes a vision of society that accords with CEFR–ELT implementation. Our aim is to contribute to the development of a counter-discourse that challenges the broader world-view underpinning ELT.     

Acaricidal activities of some essential oils and their monoterpenoidal constituents against house dust mite, Dermatophagoides pteronyssinus （Acari： Pyroglyphidae）

INTRODUCTION Among several species of the family Pyro- glyphidae, Dermatophagoides pteronyssinus and D. farinae, have been found to be the predominant mites of household dust accounting for about 80%~90% of the total mite populations and are important sources of allergens worldwide inside homes in humid geo- graphic areas (Hallas, 1991; Arlian et al., 1992). Both house dust mites are found in homes in various areas of Egypt (Rezk, 2004; Rezk et al., 1996). They are a major cause of res…     

Inter-Library Loan Service in the Kingdom of Saudi Arabia: A Case Study of Medical Libraries

The last 20 years have seen a marked increase in co-operation among Saudi medical libraries, with inter-library loan service at the forefront. This is an investigation of the current situation of co-operative inter-lending and resource sharing among medical libraries in the Kingdom of Saudi Arabia. The study discusses various methods for providing inter-library loan service including direct inter-lending, lending through union catalogs, and centralized lending. Other resource sharing activities are also described. The case study methodology was employed. Documents, interviews, and personal conversations were utilized to provide needed information. A number of medical libraries were chosen, and their inter-library loan requests for the year 1995 were thoroughly investigated. Results are analyzed, and some concluding remarks for future action are presented.
