College enrollments are shown to have increased since the 1970s for majors in computer science, engineering, and business, and to have decreased for the biological and social sciences, the humanities, and education. In both the 1970s and the 1980s, high average levels of high-school achievement are observed for declared college majors in science and engineering fields. Education and business majors display records of relatively low average levels of achievement in high school, as do college dropouts, whatever their college major. 相似文献

Little is known about ethnic differences in highbrow cultural interests, because research on social differentiation in cultural participation has traditionally focused on educational or income inequalities. Employing data from the Netherlands’ Longitudinal Lifecourse Study 2010 we explored the extent to which educational attainment, national identification and social integration explain inequality in cultural participation among Turkish and Moroccan immigrants, and to what extent the effect of education was moderated by aspects of social identification and integration. Our results indicate that Turks and Moroccans, who identify more with the Netherlands and have a social network that includes larger numbers of Dutch and higher educated friends, are more active in the cultural realm. Most interestingly, we found that strong identification with Dutch society actually moderates the relationship between an immigrants’ educational attainment and their cultural participation: that is, highly educated people of Turkish and Moroccan descent, who strongly identify with the Netherlands, participated more in highbrow culture than their highly educated counterparts who identified less with the Netherlands. 相似文献

Objective:
To support clinical researchers, librarians and informationists may need search filters for particular tasks. Development of filters typically depends on a “gold standard” dataset. This paper describes generalizable methods for creating a gold standard to support future filter development and evaluation using oral squamous cell carcinoma (OSCC) as a case study. OSCC is the most common malignancy affecting the oral cavity. Investigation of biomarkers with potential prognostic utility is an active area of research in OSCC. The methods discussed here should be useful for designing quality search filters in similar domains.Methods:
The authors searched MEDLINE for prognostic studies of OSCC, developed annotation guidelines for screeners, ran three calibration trials before annotating the remaining body of citations, and measured inter-annotator agreement (IAA).Results:
We retrieved 1,818 citations. After calibration, we screened the remaining citations (n = 1,767; 97.2%); IAA was substantial (kappa = 0.76). The dataset has 497 (27.3%) citations representing OSCC studies of potential prognostic biomarkers.Conclusions:
The gold standard dataset is likely to be high quality and useful for future development and evaluation of filters for OSCC studies of potential prognostic biomarkers.Implications:
The methodology we used is generalizable to other domains requiring a reference standard to evaluate the performance of search filters. A gold standard is essential because the labels regarding relevance enable computation of diagnostic metrics, such as sensitivity and specificity. Librarians and informationists with data analysis skills could contribute to developing gold standard datasets and subsequent filters tuned for their patrons'' domains of interest. 相似文献
