In Grutter vs. Bollinger, the U.S. Supreme Court ruled that the use of race as one factor, among many in admissions decisions is constitutional. It is not known, however, whether future legal opinions will continue to uphold the use of affirmative action policies. Some have argued that class-based preferences can achieve many of the same goals as in affirmative action while being more likely to withstand legal challenges. To date, no empirical studies have been conducted on the potential impact of a class-based admissions policy if implemented at an undergraduate institution. This paper reports on a study at a selective public college and compares a number of outcomes under three admissions models: the original admissions decisions, a purely academic model, and an socio-economic status (SES)-based model. The findings showed that use of the SES-based model would have led to a more academically qualified class than in the original admitted class while maintaining substantially greater student diversity that was found under the academic model. An admissions policy based on preferences for socio-economically disadvantaged applicants appears to hold promise for other colleges and universities with similar institutional and applicant characteristics. The ideas and research design reported in this paper are based on the doctoral dissertation study of the second author, Undergraduate Admissions Models Incorporating Socioeconomic Factors (Johnson, 2000). 相似文献

In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper,
I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining
exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm
shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking
to another and an easy back-and-forth switch between paradigms. Since Kuhn’s paradigms are self-enclosed and incommensurable,
there is no objective standard by which one paradigm can be shown to be superior to the other. But Halloun uses ‘viability’
as a standard for paradigm choice. Underlying all of this is the more basic question of whether the history of science is
an appropriate metaphor for student progress in the classroom. I conclude with some brief thoughts on this question. 相似文献

Network manufacturing has been rapidly developed and is going to play an important role in modern industry. The core of network manufacturing of mechanical products is the design and manufacturing based on the computer network technology. A network framework is inuoduced for manufacturing mechanical components at two main levels. On the design level features of the component are initially studied based on the structure and functions of the component. Details of the design procedure and contents are then analyzed with three main kinds of components. In this stage, selection of materials, calculation of stress and deflection under load, determination of the size are carried out using CAD. On the manufacturing level various aspects of CAPP are discussed, including the principle and the modes of positioning the component, the exerted clamping forces, cutting engagement and input parameters, machine tools used, and machining fluids if necessary. Finally a prototype of the network framework is presented with several pieces of data terminal equipment through a local area network, the topological structure, and data sharing and security, without concerning the use of the concurrent engineering techniques and virtual manufacturing, and virtual measuring techniques. 相似文献

INTRODUCTION Saccharomycete, closely linked with human life, is the only microbe that has been utilized to the extent of over a million tons in the world, and is one of the modelled biological bacteria mostly used in modern genetic engineering. Since there are no effective online instruments for measuring the production or resultant concentration, which is a very important quality index in fermentation process, soft sensors (Martin, 1997; Tham et al., 1991; Assis and Filho, 2000; Salgad… 相似文献
