Susan Halford 《Gender, Work and Organization》2006,13(4):383-402
In the modern western world, the discursive construction of fatherhood and everyday fathering practices has been underpinned by the spatial separation of work from home, of public from private. However, increasing numbers of employees are now working from home and a disproportionate number of these are men with young children. This article draws on new empirical research to examine the implications for fathers and for organizations as home‐working disrupts earlier spatial configurations of fatherhood and fathering practices. The article concludes that as the spatial boundaries between home and work collapse, new accommodations between fatherhood/fathering and organization are emerging. However, these are underpinned by a traditional gender division of labour in the household. More broadly, these findings confirm the inadequacy of static distinctions between public and private, showing that while such distinctions are still used to mark space and time, this is relational, contingent and unstable. 相似文献

农村义务教育财政体制是中国财政体制的重要组成部分,与农村社会经济发展和财政体制变化息息相关。建立一套完善的具有评价、监测、预测和决策功能的农村义务教育财政体制发展评价指标体系,对于义务教育事业的发展,国民整体素质的提高,“三农”问题的解决具有十分重要的意义。基于此,作者从农村义务教育财政体制研究现状出发,在论述其应遵循的评价原则的基础上,对其进行定性与定量的分析和描述,提出建立中国农村义务教育财政体制发展评价指标体系的基本构想。 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

AIDS education started very early in Zimbabwe and is now compulsory in all schools. This evaluation documents the development of the primary and secondary school AIDS Action Programme from 1991 to 1998. Six programme aspects were evaluated: programme start-up, planning and management, development of syllabi and materials, teacher training, research, monitoring and evaluation, and co-ordination. The Programme drew on resources from within the existing educational system. Due to broad-based consultation and participation, it was supported by Government and partners. Flexible management ensured implementation of mid-course corrections. It was concluded that school AIDS programmes should stress participatory teaching and learning methods and life-skills training. Curriculum writers and teachers needed training and supervision in participatory techniques. Cluster workshops between district and school levels were needed to strengthen the cascade model of teacher training that had been adopted. Systematic research, monitoring and evaluation were essential, including follow-ups to baseline surveys. The Zimbabwean programme was well-designed, relatively inexpensive and replicable. 相似文献

Rainfall interception by Santa Monica's municipal urban forest 总被引:4,自引:2,他引:2
Effects of urban forests on rainfall interception and runoff reduction have been conceptualized, but not well quantified. In this study rainfall interception by street and park trees in Santa Monica, California is simulated. A mass and energy balance rainfall interception model is used to simulate rainfall interception processes (e.g., gross precipitation, free throughfall, canopy drip, stemflow, and evaporation). Annual rainfall interception by the 29,299 street and park trees was 193,168 m3 (6.6 m3/tree), or 1.6% of total precipitation. The annual value of avoided stormwater treatment and flood control costs associated with reduced runoff was $110,890 ($3.60/tree). Interception rate varied with tree species and sizes. Rainfall interception ranged from 15.3% (0.8 m3/tree) for a small Jacaranda mimosifolia (3.5 cm diameter at breast height) to 66.5% (20.8 m3/tree) for a mature Tristania conferta (38.1 cm). In a 25-year storm, interception by all street and park trees was 12,139.5 m3 (0.4%), each tree yielding $0.60 (0.4 m3/tree) in avoided flood control costs. Rainfall interception varied seasonally, averaging 14.8% during a 21.7 mm winter storm and 79.5% during a 20.3 mm summer storm for a large, deciduous Platanus acerifolia tree. Effects of differences in temporal precipitation patterns, tree population traits, and pruning practices on interception in Santa Monica, Modesto, and Sacramento, California are described. 相似文献

William S. Pease 《Risk analysis》1992,12(2):253-265
The extent of carcinogen regulation under existing U.S. environmental statutes is assessed by developing measures of the scope and stringency of regulation. While concern about cancer risk has played an important political role in obtaining support for pollution control programs, it has not provided the predominant rationale for most regulatory actions taken to date. Less than 20% of all standards established to limit concentrations of chemicals in various media address carcinogens. Restrictions on chemical use are more frequently based on concerns about noncancer human health or ecological effects. Of the chemicals in commercial use which have been identified as potential human carcinogens on the basis of rodent bioassays, only a small proportion are regulated. There is an inverse relationship between the scope of regulatory coverage and the stringency of regulatory requirements: the largest percentages of identified carcinogens are affected by the least stringent requirements, such as information disclosure. Standards based on de minimis cancer risk levels have been established for only 10% of identified carcinogens and are restricted to one medium: water. Complete bans on use have affected very few chemicals. The general role that carcinogenicity now plays in the regulatory process is not dramatically different from that of other adverse human health effects: if a substance is identified as a hazard, it may eventually be subject to economically achievable and technically feasible restrictions. 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
