This attempt to objectively assess the costs and benefits of involvement in the harambee education movement for individuals and families is directed at policymakers and is an exercise in policy analysis. Evaluative studies of this nature are essential to the improvement of the of the overall quality of policymaking. Despite general agreement that harambee education projects involving secondary schools differ in many ways from types of self-help projects, few attempts have been made to assess the long-term social impact of the harambee education movement. For nearly 2 decades Kenya's harambee movement has flourished and has been largely viewed as a positive contribution to national development. Between 1969-79, the total value of contributions to self-help projects rose from around $6 million to almost $27 million, demostrating the substantial inputs of local communities to the economic growth of the country as a whole. Policymakers, after initial reservations about independent self-help, in recent years have come to rely on such activities as complementary to the government's efforts. Self-help activities aimed at expanding educational opportunity are the most significant in terms of both monetary resources expended and the scope of human involvement. Benefits are difficult to extimate. The growing number of students in harambee schools does not necessarly indicate that the majority of these students are acquiring marketable skills or that their consequent levels of academic training will prepare them to complete successfully in the job market with the average student educated in government-sponsored schools. The evidence, in fact, clearly points in the opposite direction. Yet, politicians, policymakers, and citizens continue to regard harambee activities for expanding educational opportunities atall levels as necessary contributions to Kenya's development program and to individual achievement. The direct cost to government for harambee education can be compared with the direct private expenditure on this type of ecucation. The 1976 annual private investment in harambee education was $45 million. The most direct benefits from harambee efforts are reaped by wealthier regions and communities in Kenya. The greaes social benefits derived from the government's policy toward the harambee school movement are political benefits. By symbolically drawing linkages between its national development strategy and independent self-help activities, the government can elicit the tacit support of rural communities. Direct social costs of such a policy are minimal. The indirect, long-term costs may result in disastrous, unintended consequences as the pool of educated and unemployed youths expands and as resulting ethnic and class inequalities sharpen and crystallize.  相似文献

This paper presents and discusses three cases of cadavers found, unburied, in the province of Venice, Northern Italy. In each case, all insect species playing some role in carrion decay processes, both sarcophagous and their predators, found on or in the bodies, were collected and determined. In one case, many larvae of the black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae) were found and are reported, for the first time in Italy, as necrophagous. Experimental breeding of some fly species was also carried out in controlled temperature and humidity conditions. In particular, it was of interest to know how the Neotropical black soldier fly modified its life-cycle to adapt to a temperate climate. It was thus possible to establish the rate of larval growth and timing of pupation, emergence, oviposition and hatching in various external conditions. The postmortem interval (PMI) established by identifying the life-cycle stages of dipterofauna were later confirmed in all cases through police investigations and the results of forensic analyses.  相似文献

As developmental scientists cease to perceive adolescence as a period of inevitable turmoil and adopt the Positive Youth Development (PYD) perspective, psychometrically sound measurement tools will be needed to assess adolescents’ positive attributes. In this article we examine the longitudinal stability of the very short version of the PYD scale developed as part of the 4-H Study of PYD. Using a sample of 7,071 adolescents (60 % female) followed between Grades 5 and 12, our results suggest general stability of PYD across adolescence, both in terms of mean levels and rank-order stability. We also show that both a global measure of PYD and the individual Five Cs of PYD consistently correlate with important criterion measures (i.e., contribution, depressive symptoms, and problem behaviors) in expected ways. Although our results suggest weak relationships among our three criteria, we especially note that across adolescence PYD becomes more strongly correlated with contribution but less strongly correlated with depressive symptoms, and that confidence becomes more strongly related to depressive symptoms. We discuss implications for use of the present PYD measure in youth development programs.  相似文献

ABSTRACT

This paper examines the role that Pentecostalism plays in stimulating entrepreneurial spirit and innovation in Ghana. The study adopts an ethnographic approach, and focuses on the Goka Prayer Camp of the Church of Pentecost in the Jaman North District of the Brong Ahafo Region of Ghana. It is grounded in Weber’s theory of religion as a catalyst for the development of capitalist societies and focuses of religious doctrines, leadership, and institutional networks. Key findings indicate that there is a nexus between Pentecostalism and entrepreneurship development in Ghana. The study showed that Pentecostalism encourages self-determination, self-reliance, and entrepreneurship initiatives among believers due to its prosperity doctrine which states that because believers share in the victory of Jesus Christ over sin, poverty and suffering, they are destined to prosper once they have embraced the faith, maintained strict moral discipline and paid tithe. In addition, Pentecostalism is seen to provide spiritual backing for entrepreneurship by freeing people from ancient superstitious beliefs, and fears that they will be accused of witchcraft, victimised, or die once they become successful. Moreover, the explicit engagement of Pentecostal leaders in the pursuit of material wellbeing sets the pace for members to follow. However, in spite of the role of this strand of Christianity in motivating individuals to engage in entrepreneurial activities, we found that they provide weak networks and institutional support, apart from those in the spiritual domain, to facilitate entrepreneurship development among members. It is rather members of the top hierarchy that appear to benefit from these social networks.  相似文献

Community college (CC) students make up 45% of American undergraduates, but little is known about their experiences of intimate partner violence (IPV), or accompanying service use and needs. The current study used a sequential confirmatory mixed methods design among a simple random sample of female CC students (n?=?435), of whom 112 have experienced IPV in the past 12 months. Of these IPV survivors, 20 participated in qualitative follow-up interviews. The study assess use and perceived usefulness of college and community based resources, extent of social support, and perceived need for and barriers to service access. Campus based resources were rated as more useful than community based resources. Faculty were identified as important supports for survivors. Those experiencing IPV reported lower rates of social support compared to other students. A range of supports and services were endorsed as possibly useful by survivors. Survivors need services to address life generated risks that compound barriers to college completion created by abuse. CC survivors often balance work and parenting with education, and may benefit from different services than survivors in other educational settings.  相似文献

Students of political motives have had difficulty relating operational indicators to the conceptual framework (associated with Clark and Wilson) that has dominated the field. The present analysis suggests that since this framework is concerned with organizational incentives rather than with individual motives, some fine tuning of the three dimensions included in the original typology may be in order and two additional dimensions need to be added. While this revised framework does not lend itself to the tangible versus nontangible motives overlay conventionally associated with the original framework, a perhaps more useful overlay is suggested which may contribute to a better understanding of what distinguishes party activists from those persons who restrict themselves to more elementary forms of political expression.  相似文献
