Latent class Poisson count models are used to analyse a sample of Danish test score results from a cohort of individuals born in 1954–1955, tested in 1968, and followed until 2011. The procedure takes account of unobservable effects as well as excessive zeros in the data. We show that the test scores measure manifest or measured ability as it has evolved over the life of the respondent and is, thus, more a product of the socioeconomic status of the parents and the human capital formation process than some latent or fundamental measure of pure cognitive ability. We find that variables which are not closely associated with traditional notions of intelligence explain a significant proportion of the variation in test scores. This adds to the complexity of interpreting test scores and suggests that school culture and possible incentive problems make it more difficult to understand what the tests measure.  相似文献

Increasing evidence from observational studies indicates that students attending minority segregated schools are at risk for constrained performance in reading. However, analyses of data gathered under observational conditions may yield biased results. Using data from the Early Childhood Longitudinal Study, 1998–1999 Kindergarten Cohort, this study used propensity score matching to address selection bias due to students’ observed socio-economic, literacy, and social-emotional background characteristics, allowing for a less biased estimate of minority segregated schooling on African-American, Latino, and European-American students’ reading gains in first grade. We found that African-American students attending segregated schools made less gain in reading across the first grade year than African-American students in non-segregated schools. There was no evidence for significant negative effects of segregation on reading gains for Latino and European-American students.  相似文献

The problem of how to rank academic journals in the communication field (human interaction, mass communication, speech, and rhetoric) is one of practical importance to scholars, university administrators, and librarians, yet there is no methodology that covers the field's journals comprehensively and objectively. This article reports a new ranking methodology based in empirical criteria. The new system relates independent measures of the prestige of the field's doctoral departments to information about where faculty members from those departments have published scholarly articles. This new approach identifies the field's most influential journals as those that more frequently publish the work of the field's top scholars and programs as perceived by their peers. This system was used to compute prestige weights (P-weights) for 65 communication journals. P-weights were found to be strongly correlated with ISI Web of Science journal impact factor scores and can be used to identify an overall prestige hierarchy for communication journals as well as prestige rankings by subject specialty.  相似文献

As reference work changes dramatically due to computer technology, tangible reference collections are disappearing from academic libraries in many fields. Such is not the case in music research libraries, however. While many important online music reference resources exist, many print resources remain vitally important, and because of limited funding, they are unlikely to be digitized soon. Music libraries and music reference collections are currently a combination of traditional and online resources, enhanced by human expertise. This beneficial combination should be maintained.  相似文献

研究表明,本届比赛中孟加拉队主要依靠5名击球员全面、高效的击球得分获得比赛胜利,而中国队仅依靠胡婷婷等队员的个人发挥;中国队缺少高水平投球配合的击球练习而导致的经验不足是影响中国队员击球得分的主要原因。建议全面提高投球训练等方法来进一步提高中国女子板球队的击球得分能力。  相似文献

The selection of students is a critical issuecurrently facing South African higher educationinstitutions. The identification and selection ofdisadvantaged students with the potential to succeedin mathematics- and science-based study is aparticularly pressing problem. The new South Africanhigher education law requires that selection is donein a fair and transparent manner. Selection has to befollowed by adequate support for selected students tosucceed in their study programmes. Issues of accessare closely coupled to issues of retention andsuccess. The research results discussed in this paperillustrate how these issues can be successfullyaddressed and how selection fairness and effectivenessmay be optimised under the constraints of selectionefficiency. An optimal solution can be found bydeveloping test specifications and selection cut-offvalues based on the teaching programme for which theselection is done. The resulting close fit betweenselection testing and teaching after selection leadsto a reasonable expectation of success for selectedstudents in the study programme. Under suchconditions, selection can be seen as a contract toteach at the student's level.  相似文献
