Severe underrepresentation of African-Americansamong postsecondary faculty is often linked toeducational pipeline supply problems,while institutional variations in demandfor black faculty labor and barriers to theirrecruitment and retention receive less empiricalattention. Using a nationally representative sample ofcollege faculty from a wide array of institutions andscience disciplines, this study investigates linksbetween internal organizational conditions and blackfaculty representation. Hypotheses derive from competingexplanations of the role of race in academicorganizations: institutionalized discrimination to protectdominant group privileges; statistical discriminationbased on expectations of racial group differences inacademic preparation; labor supply and politicalconstraints on black faculty recruitment. A multivariateanalysis examines organizational conditions that promoteor curb these dynamics and their relationship to blackappointments at different tenure levels. Results indicate that although the discipline-specificblack doctoral labor supply is a powerful constraint onthe representation of black faculty, selectiveorganizational contexts are substantial influences as well. Although we find little evidence thatinsulation from competition or segmented faculty labormarkets influence the racial composition of faculties,black faculty are more often found whereinstitutionalized discrimination may be checked by greaterformalization and black constituencies on campus.Consistent with statistical discrimination, blackfaculty are poorly represented at research-orientedinstitutions, even controlling for the scholarly reputationof doctoral credentials. 相似文献

Four theoretical frameworks were used to explore causations of turnover amongst high school teachers in Nigeria: (1) teachers’ personal health, (2) work–family life, (3) job satisfaction, and (4) actual turnover intention. Quantitative data were obtained from 925 public high school teachers in Ogun State, South-Western Nigeria. Cronbach's Alpha reliability procedure, regression modelling and t-test were used to analyse a total of 96 causations of turnover. Ad hoc analysis returned an Alpha value of 0.78. However, this improved to 0.93 when the causation factors were reduced to 64 – those with highest item-rest and itemtotal correlations. The findings showed that job (dis)satisfaction, personal health and work– family life conflict are prominent amongst the issues that trigger the intention of Nigerian high school teachers to quit their jobs voluntarily. Insights from the findings will help funding administrators in prioritising strategic decisions around mitigating turnover. 相似文献

The usefulness of a particular standardized achievement test with a specific population may be determined largely on the basis of experience. Sixty-six behaviourally disturbed students were administered portions of a test battery including the Reading Recognition subtest of the Peabody Individual Achievement Test (PIAT), PIAT Reading Comprehension, the Reading subtest of the Wide Range Achievement Test (WRAT), and Stanford Diagnostic Reading Test (SDRT); PIAT Mathematics, WRAT Arithmetic, Stanford Diagnostic Mathematics Test (SDMT), and KeyMath Diagnostic Arithmetic Test. Toward the end of the academic year, teachers estimated students' grade levels in reading and mathematics. Results indicated that, in mathematics, the SDMT and the PIAT predicted teachers' ratings equally well and better than the other tests; in reading, all tests predicted teachers' ratings equally well except for the PIAT Reading Comprehension, which performed less well than others. Explanations for these results are offered, together with suggestions for identifying achievement tests suitable to specific populations. 相似文献

Twenty-four children with conduct disorders were familiarized with a pattern-matching task, and their self-efficacy expectations for this task were assessed. Subjects were then given either “Success” or “Failure” feedback for a series of similar problems, and their self-efficacy was reassessed. Finally, task persistence was evaluated by allowing subjects to attempt as many additional pattern-matching problems as they wished, with all subjects receiving failure feedback. Results indicated that, although the two groups of subjects were initially similar, the success group's self-efficacy was significantly higher following feedback. The success group also attempted significantly more problems while later receiving failure feedback, and there was a significant positive correlation between task persistence and the second self-efficacy rating. These findings were related to Bandura's self-efficacy theory and to educational programming for conduct-disordered children. 相似文献

In the late 1950s, a health charity, known as the National Foundation for Infantile Paralysis (March of Dimes), organized American teens into volunteer divisions to fight polio, as well as tame adult anxieties surrounding juvenile delinquency. The alliance that developed permitted the NFIP to increase its influence and revenue, while granting teens an opportunity to assert their cultural power and challenge negative stereotypes. Although the NFIP nurtured and at times dominated the relationship, young volunteers joined for their own reasons and shaped the program to suit their own aspirations and interests. 相似文献
