城市低收入保障制度与反贫困的公共政策   总被引:2,自引:0,他引:2  
城市低收入保障制度实施中“应保未保”的现象较为普遍,低收入保障所需资金的缺口较大,缺乏全国统一的贫困标准使得其随意性很大。解决这一社会问题必须从近期和远期两个目标入手,近期目标是尽快遏制城市贫困人口剧增的势头,防止在深化改革的过程中出现快速增长的新生贫困人口;远期目标是立足最终消除城市贫困现象。  相似文献

In the wake of the recent announcement by the State Council concerning the provision of public rental housing across China, and the gradual reform of China's household registration system (hukou), this article explores how potential adjustments in government housing policies (namely access to public rental housing) influence the housing preferences of temporary migrants who are currently residing inside the chengzhongcun (urban villages) of Shenzhen. The results indicate that dissatisfaction with rental cost and living conditions in these urban villages are the key reasons for migrants wishing to move into public rental housing if it is offered to them — and not the fact that they are treated differently within the hukou system. Public rental housing is welcomed in particular by newly arriving migrants who live outside the Shenzhen Special Economic Zone (SEZ), and migrants who have decided to remain in Shenzhen for the foreseeable future. By contrast, dissatisfaction with urban villages is the sole contributor to housing preferences for those residing inside the SEZ.  相似文献

随着改革开放的深入和中国加入WTO,社会越来需要要既具备国贸专业知识,又能运用流利的英语与外界交往的高素质人才。在当前就业形势日趋严峻的情况下,提高国际贸易专业毕业生的专业英语素质,不但能提高其就业竞争力,而且能为我国经济与社会发展提供强有力的人才支持和智力保证。要应对挑战,当前国际贸易专业英语教育改革就应当与市场需求接轨、以就业为导向,并在此基础上提出国际贸易专业英语课堂教学模式的构想。  相似文献

随着互联网的迅速发展,微博作为信息和思想交流的载体之一,正在逐步成为思想政治教育工作的一种载体,克服了信息传播在时间和空间上的局限性.高校隐性思想政治教育采取相对隐蔽的教育方式,潜移默化地影响大学生的人生观、价值观等.因此,通过调查研究大学生使用微博的情况,使我们看到了微博对大学生的影响,以及微博应用于高校隐性思想政治教育工作中存在的一系列问题,从而提出进一步优化微博在思想政治教育中作用的建议和对策.  相似文献

Aims: To assess and compare the direct healthcare and non-healthcare costs and government subsidies by body weight and diabetes status.

Methods: The Australian Diabetes, Obesity and Lifestyle study collected health service utilization and health-related expenditure data at the 2011–2012 follow-up surveys. Costing data were available for 4,409 participants. Unit costs for 2016–2017 were used where available or were otherwise inflated to 2016–2017 dollars. Age- and sex-adjusted costs per person were estimated using generalized linear models.

Results: The annual total direct cost ranged from $1,998 per person with normal weight to $2,501 per person with obesity in participants without diabetes. For those with diabetes, total direct costs were $2,353 per person with normal weight, $3,263 per person with overweight, and $3,131 per person with obesity. Additional expenditure as government subsidies ranged from $5,649 per person with normal weight and no diabetes to $8,085 per person with overweight and diabetes. In general, direct costs and government subsidies were higher for overweight and obesity compared to normal weight, regardless of diabetes status, but were more noticeable in the diabetes sub-group. The annual total excess cost compared with normal weight people without diabetes was 26% for obesity alone and 46% for those with obesity and diabetes.

Limitations: Participants included in this study represented a healthier cohort than the Australian population. The relatively small sample of people with both obesity and diabetes prevented a more detailed analysis by obesity class.

Conclusion: Overweight and obesity are associated with increased costs, which are further increased in individuals who also have diabetes. Interventions to prevent overweight and obesity or reduce weight in people who are overweight or obese, and prevent diabetes, should reduce the financial burden.  相似文献

It is necessary to reconsider the assumptions upon which the process of implementing compliance with ethical programs rests, in both theoretical and practical terms. These assumptions should hinge on organizational enablers that allow embeddedness of codes of ethics in the web of an organization's processes. This article sets out to describe an approach that will facilitate implementation of codes of ethics in construction organizations and a comprehensive literature survey approach is adopted to achieve this. The paper equally employs the application of the European Foundation for Quality Management (EFQM) model as a tool to stimulate ethical behavior in an organization, with the focus on the enabler criterion of the model. The authors discuss organizational enablers in relation to the implementation of ethical codes. The study demonstrates how ethics can be managed in an organization by proposing a framework to enhance codes of ethics embeddedness in the web of an organization. The paper indicates current research gaps and future opportunities for both academics and practitioners.  相似文献
