Based on two recent teacher development efforts in Pakistan, this chapter examines efforts to promote teacher collegiality within these initiatives. The chapter first describes relevant contextual differences among schools in Karachi and summarizes the history of the two projects within this context. It then analyzes similarities and differences across these two projects in how they dealt with collegiality and professional development. While participants in both projects made progress in ameliorating extreme forms of teacher isolation and authoritarian relationships, they also discovered that balancing increased collegiality within a hierarchy of responsibilities and rewards is a difficult and elusive goal. 相似文献

The expansion and transformation of Malaysian universities have generated major changes in the nature of academic employment and the structure of academic promotion in higher education institutions. These changes have considerable implications, in particular for the policy and practice of academic promotion in the public universities. We argue that despite sharing one common grade and salary system, distinct and significant differences exist in the academic promotion systems of the public universities. Drawing on one recent study on the academic promotion process in Malaysian public universities to contextualise our discussion, this paper highlights the complexity in the promotion process in these institutions. It also discusses and articulates the attendant issues and challenging aspects of the academic promotion process. We argue that the interrelated issues and challenges, and certain academic practices and habits stemming from the pressure to gain a promotion are pervasive, and that they affect the academic value system and work culture. We conclude by asserting the importance of applying a consistent standard for promotion within a single salary system and that the academic promotion system in the public universities should ultimately affirm and communicate core academic values, and also aim at obtaining evidence of excellent accomplishments. 相似文献

This study focused, for the first time, on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake(MSC). The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles(J2 s) of root-knot nematode, Meloidogyne javanica. The results show that a 35 ppm(parts per million) concentration of a sonicated extract(SE) sample of MSC caused 65% J2 s mortality at 18 h exposure period in vitro. It also significantly suppressed the root-knot index(RKI=0.94) in tomato roots. The lethal concentration values for SE were 51.76, 29.79, and 13.34 ppm,respectively, at 6, 12, and 18 h of the exposure period, and the lethal concentration values for the non-sonicated extract(NSE)sample were 116.95, 76.38, and 55.59 ppm, respectively, at similar exposure time. Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC. Because of the high extraction efficiency of metabolites in the SE, all treatments of SE were shown to be antagonistic to J2 s. Thus, this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops. 相似文献

It is shown that for DC networks in which certain components are allowed to vary, the worst case DC problem can be solved by solving a linear programming problem. The constraints used in the linear programming problem are determined from the elements tolerance regions. This enables us to obtain the worst case solution without having to compute the gradient of the network functions. 相似文献

Academic dishonesty is believed to have predictive ability for subsequent behaviours in the workplace. This study adds to the literature by investigating Malaysian business students' attitudes to academic dishonesty and their attitudes to ethics issues in business. This study also explores the association between these two constructs. The form of academic dishonesty being investigated here is related to assignments, quizzes, and examinations. Employing data collected from 153 business students from different academic years, this exploratory study concludes that business students may have found that some level of dishonesty is acceptable in some academic settings as well as in business settings. The study's outcomes highlight the possibility of using students' attitudes to academic dishonesty to explain their attitudes to ethics in business contexts. The findings of this study, to a certain extent, indicate that years spent in business education might contribute to such unfavourable attitudes. This exploratory study also draws attention to several issues related to the teaching of ethics within business education. 相似文献

Multiple regression is being used by some investigators to determine the unique statistical relevance of potential sex bias for various groups of individuals. The following article shows that the presence of multicollinearity among the independent variables can cause misleading interpretations of the resulting regression weight for sex coded as a dummy variable. An alternative approach is proposed with an example to demonstrate the interpretation of the results. Questions are raised concerning the interpretation of some previous research. 相似文献

The literature indicates that glucose deprivation, dehydration, decreased sleep quality and quantity, and mood changes, independently and adversely can influence cognitive functions and therefore learning. The Ramadan fast is an annual religious act undertaken by Muslims where individuals refrain from consuming food and fluid during daylight hours, daily over 30 days. Alteration in eating times and sleep–wake cycles lead to a disruption in the body's daily circadian rhythm resulting in sleep perturbations and mood swings. Consequently, Ramadan fasting is linked to daytime lower glucose concentration, dehydration, decreased sleep quality and quantity, mood swings and elevated subjective feelings of fatigue and malaise. This review highlights how Ramadan fasting potentially poses learning difficulties as a result of the independent and/or combined effects of these factors. 相似文献
