我国农地制度变迁的历史考察及绩效分析   总被引:19,自引:0,他引:19  
有什么样的农地制度就会产生什么样的制度绩效。建国后我国农地制度发生了若干次大的变动,其中,有的是强制性制度变迁,有的是诱致性制度变迁,总体上看,诱致性制度变迁一般都取得了较优的绩效,如家庭联产承包责任制。但由于制度的边际效用是递减的,因此,家庭联产承包责任制不可能是我国农地制度变迁的最后归宿,必将继续发生变动,并很有可能最终被符合市场经济原则的资本雇佣土地的制度所取代。  相似文献

湖南“二王”与近代湖南书院改制   总被引:1,自引:0,他引:1  
王闿运与王先谦在近代史上并称湖南“二王,”他们都与湖南书院改制有非常密切的关系。王闿运不认同西式学堂教育,主张在传统书院教育体制之内改善书院教育,船山书院在其主掌之下至1915年方改为学堂;王先谦接受了西式学堂体制,但其坚守学堂不能离“道”而行,在湖南书院改制中呈现出双重趋向。“二王”与湖南书院改制的关系,透射出传统型知识分子在晚清变局中的复杂心态。  相似文献

论合同法上的情事变更原则   总被引:1,自引:0,他引:1  
法律上对情事变更原则的适用规定了严格的条件,适用情事变更原则的法律效力主要体现变更合同、解除合同两个方面,而且情事变更与不可抗力、商业风险存在着明显的差别。社会主义市场经济的发展及与国际市场的接轨,决定了情事变更原则应当成为我国合同法上最重要的法律原则之一,它有利于进一步完善我国现行合同法律制度。  相似文献

loveLife is the largest effort ever launched in South Africa to change adolescent sexual behaviour with the aim of reducing the rate of HIV infection among 15–20 year olds by 50%, reducing other STIs, and reducing the incidence of teenage pregnancy. loveLife combines high-powered media awareness and education, development of adolescent-friendly reproductive health services, and outreach and support programmes. The 5-year research and evaluation plan includes a multi-year comprehensive observational study, tracking change in a range of behavioural indicators and in sexual health outcomes. In its first 2 years, loveLife reached more than 4 million youth. Sixty-two percent of youth and 59% of their parents/guardians recognize the brand, while the vast majority of parents (97%) and youth (89%) exposed to loveLife, identified loveLife as being positive. Challenges in the next years are the continued roll out of the programme, and the development of institutional support and behaviour change.  相似文献

This 1998 evaluation assessed the peer education programmes of HIV/AIDS projects run by four non-governmental organisations. A mini-case study approach was used and analysis was based on cross-case itemistic variables. The projects were assessed only in terms of immediate developmental outcomes to target groups rather than on long-term impact. The study concluded the following: (1) The projects had raised community awareness of HIV/AIDS; (2) Basic knowledge of HIV/AIDS was for the most part accurate; (3) There was anecdotal evidence of behavioural changes in terms of partner-reduction as reported by the projects, though the evidence was sometimes conflicting; and (4) There was evidence that certain traditional practices, which contributed to the spread of the virus (e.g. sexual cleansing and scarification), were becoming modified over time. The programmes were also instrumental in protecting human rights and enabling people living with HIV/AIDS to maintain human dignity.  相似文献

Studies comparing abusive and non-abusive parents who were abused as children are reviewed to determine protective factors that may lead to a break in the transmission pattern. Non-abusers have several factors in common. For instance: they have extensive emotional and social support from significant others. they are aware of what happened to them as children and are openly angry about their abuse. and many of them received (psycho)therapy as adolescents or young adults. Discovering protective factors by which some parents overcome a family pattern of abuse is valuable in guiding both prevention and intervention efforts. A brief discussion of the influence of methodological variations of different studies on reported transmission rates precedes the review. Furthermore. attention is given to the underrepresentation of (abusive) fathers in theory as well as in research on child abuse. The effects of undervaluation of gender differences are discussed in terms of their importance in the occurrence and (breaks in the) transmission of child abuse.  相似文献

One of the key features of Vietnamese family organization is patrilocality—the preference of married couples to coreside with the husband's parents. With data drawn from a retrospective survey of persons in 1,855 households in the largest province in the Red River Delta in northern Vietnam, we found that more than 75% of married respondents reported having lived with the grooms' family after marriage. The proportion of newly married couples that follow the patrilocal custom appears to have increased in recent decades, although the average duration of coresidence has declined. Some aspects of modernization, especially nonagricultural occupations and later age at marriage, contribute to a lower incidence of intergenerational coresidence, but the underlying cultural preference to live with the grooms' parents immediately after marriage appears to have become stronger in Vietnam. In contrast to some features of traditional family life that conflict with modernity, intergenerational coresidence can be quite functional in modernizing societies.  相似文献
