This study’s main purpose was to determine whether or not standard predictors of college “success” might perform more satisfactorily than usual if a 2-valued criterion based on dropouts was employed. Discriminant analysis, when applied to 624 matriculants at the University of Pennsylvania, identified correctly 93 percent of the graduates and 88 percent of the academic dropouts. A small sample of students, who applied to the University of Pennsylvania but did not matriculate, was examined. A rough cost comparison estimated that failure to use the discriminant analysis procedure was in one sense costing the University of Pennsylvania about $333, 000 per year in the late 1960’s. 相似文献

The aim of the present study was to evaluate the antidiabetic and ameliorative potential of aqueous extract of Ficus bengalensis
bark in streptozotocin induced diabetic rats. The effect of oral administration of aqueous extract of F. bengalensis bark
on blood glucose, serum electrolytes, serum glycolytic enzymes, liver microsomal protein, hepatic cytochrome P-450 dependent
monooxygenase enzymes and lipid peroxidation in liver and kidney of streptozotocin -induced diabetic rats was studied. Oral
administration of Ficus bengalensis to fed, fasted and glucose loaded diabetic rats significantly [F > 0.05 (ANOVA) and P<
0.05 (DMRT)] decreased the blood glucose level at 5 hrs and restored the levels of serum electrolytes, glycolytic enzymes
and hepatic cytochrome P-450 dependent enzyme systems and decreased the formation of liver and kidney lipid peroxides at the
end of 12 weeks. Further, the aqueous extract of Ficus bengalensis at a dose of 500mg/kg/day exhibits significant antidiabetic
and ameliorative activity as evidenced by histological studies in normal and Ficus bengalensis treated streptozotocin induced
diabetic rats. On the basis of our findings, it could be used as an antidiabetic and ameliorative agent for better management
of diabetes mellitus. 相似文献

This summative/programmatic essay outlines how the field of International Communication today is underpinned by a central concern with issues of “culture.” An epistemic model for how to understand this new use of culture is sketched, arguing that the term “culture” operationalizes issues of nationalism, modernism, capitalism, postmodernism and post colonialism. The relationship of this model for media forms such as television is then undertaken. Detailed End Notes engage with relevant literature from the field of International Communication. 相似文献

In response to the proliferation of digital information accessible over networks, significant changes have taken place in library and information science (LIS) education during the last decade. To understand the changes, the study examined LIS faculty members' innovative behavior toward the end of the decade by applying a model of adoption that purports that material resources, experiential resources, value attributed to the innovation, and communication with adopters influence adoption of an innovation. The particular innovation examined was a complex, digital information-related innovation. It was termed collectively as Internet resource-based value-added processes and included the following set of processes that add value to Internet resources: (1) selection of Internet resources, (2) organization of Internet resources, (3) Internet reference services, (4) interface design in digital libraries, and (5) user analysis in digital libraries. Survey results indicated that the value LIS faculty attached to the innovation was the most influential variable in their decisions in favor of early adoption. However, communication between early adopters and late adopters in LIS education was found to be weak and not influential in the late adopters' decisions. 相似文献
