The convergent and discriminant validity of three measures of the concepts of aspiration level, ability, achievement, adjustment, and dominance were examined in the context of a multitrait-multimethod matrix. Self-reports and peer-reports on 75 Ss were employed as two measures of each trait. In addition, aspiration level was measured by the Edwards Personal Preference Schedule (EPPS) Nach scale, dominance by the EPPS (dom scale), achievement by cumulative college grade point ratio (GPR), ability by the Ohio State Psychological Examination (OSPE), and adjustment by the Bell Adjustment Inventory. Of the paper and pencil instruments, only the OSPE and EPPS (dominance scale) exhibited satisfactory convergent validity. No measure met all the requirements of discriminant validity. The desirability of establishing adequate validational evidence prior to using “trait” measures in studies relating theoretical variables was emphasized. 相似文献

Promoting minority success in the sciences: The minority opportunities in research programs at CSULA
Given the large continued investment by the federal government in programs that promote academic success and the pursuit of advanced degrees in the sciences among members groups traditionally underrepresented in the sciences, there is a strong need for research which provides rigorous investigations of these programs and their impact on the target population. The current study examines programs funded by the National Institutes of Health Minority Opportunities in Research (MORE) Division Office intended to address this underrepresentation at a minority serving comprehensive university. Academic outcomes, including college graduation and acceptance into graduate programs, among undergraduate program participants are compared against a propensity score matched comparison group. Results indicate that students supported by the MORE programs had higher GPAs at graduation, took less time to graduate, and were more likely to both graduate with a science degree and enter Master's and doctoral programs in the sciences. © 2011 Wiley Periodicals, Inc.

Recent debate on the reform of scholarly communication has focused on access issues. Although important, access is only one dimension in which the scholarly process can be transformed. Scholars are embracing highly collaborative and data‐intensive standards of practice influenced by powerful computing and network technologies. This dramatic transformation of scholarship demands a natively digital, network‐based scholarly communication system that is able to capture the scholarly record, make it accessible, and preserve it over time. I will offer a technological perspective on how these demands might be met. 相似文献
