因教致贫的社会学分析   总被引:10,自引:0,他引:10  
张国强 《高等教育研究》2007,28(3):41-45,51
因教致贫现象是社会失范的一种表现,会造成合理社会流动受阻、阶层差异代际转移、读书无用思想重现和社会不安因素积聚等社会危害。教育成本分担机制失衡、个人教育费用投入过高、弱势群体教育成本补偿不够和优质教育资源分配不均等因素是造成这一现象的主要原因。通过构建合理的教育成本分担机制、保证相对均衡的教育资源供给、实行科学的教育成本核算与收缴制度、完善教育投资收益的回馈渠道、引导理性的家庭教育投资等措施可以有效解决因教致贫现象。  相似文献

IntroductionLittle is known about the perpetrators of medical child abuse (MCA) which is often described as “Munchausen’s syndrome by proxy” or “factitious disorder imposed on another”. The demographic and clinical characteristics of these abusers have yet to be described in a sufficiently large sample. We aimed to address this issue through a systematic review of case reports and series in the professional literature.MethodA systematic search for case reports and series published since 1965 was undertaken using MEDLINE, Web of Science and EMBASE. 4100 database records were screened. A supplementary search was then conducted using GoogleScholar and reference lists of eligible studies. Our search yielded a total sample of 796 perpetrators: 309 from case reports and 487 from case series. Information extracted included demographic and clinical characteristics, in addition to methods of abuse and case outcomes.ResultsNearly all abusers were female (97.6%) and the victim’s mother (95.6%). Most were married (75.8%). Mean caretaker age at the child’s presentation was 27.6 years. Perpetrators were frequently reported to be in healthcare-related professions (45.6%), to have had obstetric complications (23.5%), or to have histories of childhood maltreatment (30%). The most common psychiatric diagnoses recorded were factitious disorder imposed on self (30.9%), personality disorder (18.6%), and depression (14.2%).ConclusionsFrom the largest analysis of MCA perpetrators to date, we provide several clinical recommendations. In particular, we urge clinicians to consider mothers with a personal history of childhood maltreatment, obstetric complications, and/or factitious disorder at heightened risk for MCA. Longitudinal studies are required to establish the true prognostic value of these factors as our method may have been vulnerable to publication bias.  相似文献

Abstract

Growth in size and popularity of the Web over the last 10 years has been remarkable. There are now many calls to make the Web the center of K-12 schooling. However, there are many problems that must be solved before the Web can be fully integrated into curricula in public schools. Such problems can be categorized as practical or pedagogical in nature. Pedagogical problems include those barriers to Web integration that are caused by the nature of the education subculture and the culture at large. These are the most difficult problems to solve and would call for a nationwide commitment to true individualized education.  相似文献

Abstract

We defend in this paper the importance of redistributing power in the field of education development by enhancing the self-sustainability of education initiatives and minimizing their roots in dependency – these as pre-requisites for improving their sustainable development outcomes. We do this by considering an education development initiative run by the Barefoot College in India, and then developing an explanatory model based in complexity theory (as expounded by Edgar Morin) and in the capability approach (as developed principally by Amartya Sen and Martha Nussbaum). We conclude that such a redistribution of power would help to ensure that education is better connected to its development context, more relevant to the interests and needs of the community it serves, and its quality enhanced. More generally, we reinforce existing arguments – but from the perspective and imperative of sustainability – why it is in the interests of policy-makers to devolve power and to provide resources to such initiatives. Doing so would enhance governments’ prospects of realizing their education and social development goals. The arrogation of power and resources towards the centre, an almost natural impulse in policy-making, is, in the end, counter-productive, and threatens sustainable education and social development.  相似文献

Research has shown that attending a relatively selective four-year college over a less selective alternative is positively related to bachelor's degree completion. This paper revisits that question with a novel dataset of over 11,000 sets of twins in the United States and information on colleges to which they apply, enroll, and potentially graduate. I show that a student's probability of bachelor's degree completion within four years increases by 5 percentage points by choosing an institution with a median SAT score 100 points higher than the alternative. Moreover, the estimated magnitude of impact is insensitive to several methodologies, including OLS, twin fixed effects, and controlling for the application portfolio. This suggests that in certain contexts, sources of bias perceived as barriers to obtaining causal estimates of the returns to college selectivity, such as unobserved family characteristics and student aspiration, may be of little concern.  相似文献
