College students with disabilities who are lesbian, gay, bisexual, or transgender (LGBT) represent diverse cultural minorities with multiple service needs involving disabilities, identities, and adjustment strategies. These students are usually accommodated in the college environment because of their disability while simultaneously marginalized based on their sexual orientation. This article discusses LGBT college students with disabilities as multiple cultural minorities with a focus on educational environments, institutional issues, and strategies for university personnel. © 2002 Wiley Periodicals, Inc.  相似文献

The prospect of European integration calls urgently for educational provision which will enable Europe's school‐leavers to understand and appraise the process. Essentially, this provision is historical. What is distinctive about Europe? What made us what we are? It is suggested that modem Europe is, at bottom, the result of two related things‐‐conflict and ideas‐‐and that the conflicts have arisen because of the ideas, and have constituted their final working‐out. Three ideas, with their related conflicts, seem fundamental, and these three pairings indicate the appropriate content for a history course for Europe's senior pupils. The three ‘ideas ‘ are the Reformation, the Enlightenment and Nationalism, and the related conflicts are the 30 Years’ War, the French Revolutionary and Napoleonic Wars and the World Wars of this century. The coverage of the first pairing is sketched as an example of how the whole course may be mounted and to introduce a master theme of European history for the last 300 years. The paper ends with a brief discussion of why other seemingly crucial factors are not selected and discussed.  相似文献

Measuring the incidence of public spending in education requires an intergenerational framework distinguishing between what current and future generations—that is, parents and children—give and receive. In standard distributional incidence analysis, households are assumed to receive a benefit equal to what is spent on their children enrolled in the public schooling system and, implicitly, to pay a fee proportional to their income. We show that, in an intergenerational framework, this is equivalent to assuming perfectly altruistic individuals, in the sense of the dynastic model, and perfect capital markets. But in practice, credit markets are imperfect and poor households cannot borrow against the future income of their children. We show that under such circumstances, standard distributional incidence analysis may greatly over-estimate the progressivity of public spending in education: educational improvements that are progressive in the long-run steady state may actually be regressive for the current generation of poor adults. This is especially true where service delivery in education is highly inefficient—as it is in poor districts of many developing countries—so that the educational benefits received are relatively low in comparison with the cost of public spending. Our results have implications for both policy measures and analytical approaches.  相似文献

This study examined the relation between language skills, gender, and relational/ physical aggression. Language skills of 100 preschoolers were assessed with 3 standardized instruments. Relational/physical aggression was rated by the children's teachers. Results indicated that relational and physical aggression tended to increase as language scores decreased. When the alternative form of aggression was held constant, girls' expressive language skills predicted relational aggression more than boys', and receptive language skills predicted physical aggression more than relational aggression, especially for boys. Classroom variables predicted relational aggression more than physical aggression. Results suggest that receptive and expressive language are important in predicting form and level of aggression. Implications for early identification of girls at risk for problem behavior in the preschool years are discussed.  相似文献

Antireflection is an essential requirement for certain optoelectronic devices. Antireflective surfaces can be generated by different methods. One method mimics the nanofeatures on the moth eye surface. This can be done by ‘soft lithography’ (SL), where nanofeatures are created on an elastomeric stamp. This stamp is then used for imprinting the pattern on other surfaces.  相似文献
