At the end of the 1970s, discrimination against women as political participants continues, but it is being challenged and, in some countries, steadily eroded. There are only eight countries in the world today in which national law excludes women from political processes that are open to men. While in most countries that have elections, women lag behind men in exercising the franchise; the tendency is for the difference in men's and women's voting rates to narrow over time in stable electoral systems. However, there is an enormous disparity between women's attainment of formal political equality and their real exercise of political power. The numbers of women in public office remains low in most countries; in very few do women fill even 10% of such positions. Yet there are scattered signs of improvement, with slowly rising numbers of women in elective and appointive offices. The real centers of political power are still overwhelmingly dominated by men, but the fact that women in most countries can enter the political contest on a routine basis is a sign that exclusion based on sex roles is diminishing.  相似文献

OBJECTIVES: To examine the effects of different forms of family violence at two developmental stages by assessing a sample of 110 Israeli children, drawn from the case files of Israeli family service agencies, studied longitudinally in both middle childhood and adolescence. METHODS: Information about the children's adjustment was obtained from parents, teachers, and the children themselves when the children averaged 10.6 and 15.9 years of age using the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), Youth Self-Report (YSR), and Children's Depression Inventory (CDI). Information about the history of family violence was obtained from the mothers, fathers, children, and social workers. RESULTS: The results paint a mixed picture of the effects of family violence on children and adolescents. The relationship between concurrent behavior problems and abuse group varied by informant and study phase, although they were strongest when children were the informants. Predictions regarding the relationship between early abuse and later adjustment were only partially confirmed. Different informants did not agree about which groups of children were most adversely affected, there was little stability over time in the pattern of reported effects, and children were more likely than other informants to report levels of maladjustment that varied depending on recent or concurrent exposure to family violence. Many families changed their abuse status over time, and children who were new victims at follow-up had the most internalizing problems. Girls were found to be at more risk for internalizing and externalizing behavior problems than boys. CONCLUSIONS: Multiple informants are necessary to evaluate and assess the effects of family violence on children's behavior. Younger children may be more susceptible to the effects of family violence than older children, but problems manifest by some children may not carry over to adolescence. Changes in family and parenting practices, as well as in children's capacity to appraise and cope with family violence may help mitigate the adverse effects of family violence.  相似文献

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献

This article investigates the gap between employers' requirements of graduates and the skills which graduates are furnished with through degree programmes in the higher education (HE) sector in the UK. A survey of 88 subject review reports prepared by the Quality Assurance Agency (QAA) for environmentally related units in the UK showed little emphasis on employability issues. Surveys of first destination statistics of a cohort of graduates from two biological degrees and from national data showed that a significant proportion of graduates were in non-science-based activities. The non-knowledge-based learning outcomes from one degree were investigated, and showed that employability aspects were partially covered in the programme, but were not always associated with secure assessments. The concept of work-related learning is defined and a conceptual framework for HE practitioners is presented that could be used when designing curricula to better map programme learning outcomes onto graduate employment.  相似文献

England's Education Action Zones are a flagship New Labour policy geared towards raising standards and reducing social exclusion in areas of educational under-performance. This introduction outlines key features of the policy, considers its broader significance in relation to new models of educational governance and pulls out some of the key issues that arise from the contributions to this special feature.  相似文献
