This paper introduces some observed sociological and cultural aspects of students. It is usually assumed that these aspects are the same as the lecturer's own, but that is not necessarily so, here in Papua New Guinea. Assignments to encourage both the change of attitude and for the practice of the technical content of courses are described.

Arguments about the rise in relative education levels of African-Americans invoke (1) improvements in the quality of schools attended by blacks or (2) affirmative action regulations affecting schools and employers. Missing from these arguments is an explanation of the emergence of black education levels exceeding those of whites once the influence of family background factors has been controlled. School quality improvements, by themselves, could not have produced high observed black...

A paper radioimmunosorbent test (PRIST) was shown to be sensitive and reproducible when used with excretory/secretory antigen of Toxocara canis second stage larvae. Whatman No. 50 filter paper (5 mm discs) gave the most consistent and clear results with antigen at a concentration of 100 μg/ml, and could be stored for up to 3 weeks in vacuo at −70°C. Antigen coated discs were incubated with test sera at 1 : 10 dilution for 3 h at room temperature (21°C), reacted with [125I]anti-human IgG for...

Objective: The aim of this anthropological study was to create an understanding of school-related violence experienced by adolescents in the context of chronic poverty in a South African community. Method: Qualitative methods of data collection such as participant observation, interviews, and group discussions were utilized for data collection. Sixteen children and three adults in turn kept diaries and wrote reports during the research period of three and one-half years (June 1992–December...

A need to reassess US medical schools' admission of African-American students exists based on recent challenges to affirmative action. The Association of American Medical Colleges (AMMC) provided US medical school enrollment data and characteristics. Measures of enrollment were constructed for each medical school and aggregated by ownership type and state. After peaking at 1311 students in 1994, African-American medical school matriculation decreased by 8.7% by 1996. This decline was...

The purpose of this analysis was to determine if there were distinct behavioral profiles involving perceived and daily stress and Africentric identity in a sample of 701 African American college students who attended eight historically Black colleges and universities. It was hypothesized that there would be a negative relationship between Africentric identity and stress and other personality dispositions that are often associated with stress, such as depression and anger A cluster analysis...

Summary A review of the organizational set‐up of a national statistical office, its staffing levels and subjects covered has been described. Two groups of employees of a statistical office are considered with respect to the teaching of statistics, namely those already in employment and those expected to be employed by a statistical office. The Statistical Training Programme for Africa (STPA), under which the present study was undertaken, improvement and strengthening of statistical training...

Do firms become more efficient after becoming exporters? Do exporters generate positive externalities for domestically oriented producers? In this paper we tackle these questions by analyzing the causal links between exporting and productivity using plant-level data. We look for evidence that firms' cost processes change after they break into foreign markets. We find that relatively efficient firms become exporters; however, in most industries, firms' costs are not affected by previous...

Protein malnutrition leads to multiple detrimental alterations of host immune responses to mycobacterial infection. In this study, we demonstrated that splenocytes from low-protein (LP) guinea pigs vaccinated 6 weeks previously with attenuated Mycobacterium tuberculosis H37Ra failed to control the accumulation of virulent M. tuberculosis H37Rv in cocultured autologous peritoneal macrophages, despite the fact that they were able to control the accumulation of virulent tubercle bacilli in...

A common dilemma facing educational planners engaged in educational reform in developing countries is the allocation of sharply-reduced resources to the expansion of school facilities versus improvement of existing school facilities (say, by raising the teacher/pupil ratio). The empirical results presented in this paper for Kenya suggest that the two interventions have diametrically opposite effects on poor and nonpoor children. An expansion of school facilities increases the enrollment of...

Sex, race, and scores on Universal-Diverse Orientation were analyzed as predictors of students' preferences for certain psychologists' characteristics. Preferences for similarity of race and sex were clear.

This survey was undertaken to determine the occlusal status of a selected group of urban Zambian Black 9-12 year old children at 5 different schools in the same geographical area in order to determine their need for orthodontic treatment. The examination criteria of the Occlusal Index of Summers (1966) were used. Six hundred and one children who had not previously received orthodontic treatment were examined. The data were analysed statistically by using the calculated Summers Index. The...

Building on previous social-psychological studies, the Prejudice Perception Assessment Scale (PPAS) was developed to measure stigma vulnerability-the phenomenon of attributing negative, interpersonal feedback to prejudice in ambiguous situations-among African American students on predominantly Euro-American campuses. This article describes the methodological procedures followed in developing the PPAS, a brief scale composed offive vignettes aimed at assessing the extent to which participants...
