以不同生产资料所有制的经营性资产价值量作为衡量主次地位的边界标准,估算第一产业公有制与非公有制的资产规模及其比重变化,并在前人估算的基础上,延伸估算第二和第三产业两种所有制的资产规模及其比重变化。结果发现:截至2012年,中国三次产业经营性总资产约为487.53万亿元,其中公有制经济的资产规模是258.39万亿元,占53%;第二、三产业非公有制经济占增加值和就业规模的比重分别为67.59%和75.20%。这表明,公有制资产仍占主体,非公有制经济贡献占优,中国社会主义基本经济制度充满活力,从而为我国社会主义初级阶段的所有制改革和坚持“两个毫不动摇”的政策提供了理论依据。  相似文献

The aim of this study was to develop a modified quantitative microbial risk assessment (QMRA) framework that could be applied as a decision support tool to choose between alternative drinking water interventions in the developing context. The impact of different household water treatment (HWT) interventions on the overall incidence of diarrheal disease and disability adjusted life years (DALYs) was estimated, without relying on source water pathogen concentration as the starting point for the analysis. A framework was developed and a software tool constructed and then implemented for an illustrative case study for Nepal based on published scientific data. Coagulation combined with free chlorine disinfection provided the greatest estimated health gains in the short term; however, when long‐term compliance was incorporated into the calculations, the preferred intervention was porous ceramic filtration. The model demonstrates how the QMRA framework can be used to integrate evidence from different studies to inform management decisions, and in particular to prioritize the next best intervention with respect to estimated reduction in diarrheal incidence. This study only considered HWT interventions; it is recognized that a systematic consideration of sanitation, recreation, and drinking water pathways is important for effective management of waterborne transmission of pathogens, and the approach could be expanded to consider the broader water‐related context.  相似文献

周紫芝是宋代唯一既大量创作乐府诗,又编辑整理前人的乐府诗,且对本朝乐府诗进行批评的著名诗人。周紫芝对乐府诗的批评以新乐府为主,并首次将关注的目光投向了宋代新乐府。周紫芝的乐府观主要表现为:在古今乐府并存的情况下,充分重视与肯定新乐府;首次对宋朝新乐府予以关注并高度评价;注重唐人新乐府与宋朝新乐府之间的影响关系。  相似文献

Voluntary work provides a major source of labor for many nonprofit organizations. Consequences of volunteers and paid staff working alongside each other in nonprofits are well documented. This article contributes to this strand of literature and investigates whether the presence of volunteer work influences paid employees' wages in nonprofit organizations. We estimated a multilevel wage equation accounting for personal characteristics of workers and characteristics of nonprofits. The analysis revealed that nonprofit organizations engaging volunteers pay lower wages to their employees. Our findings contribute to the understanding of wage‐setting behavior of nonprofits and improve the methodological approach of empirical research in this field.  相似文献

Research on the university experience of disabled students has focused on barriers in learning and teaching, while the social world of university has as yet gained little attention as a distinctive object of study. Here we examine social experience and socially imposed restrictions through the lenses of social capital and self-concept. A qualitative study investigated the formation of social capital and changes in self-concept amongst physically disabled Australian university students. Data were collected through semi-structured interviews and analysed using a grounded theory approach. The study found weak social attachments at university, but stronger attachments outside. Self-concept did not appear to be structured in any direct way by university-generated social capital, partly as a consequence of its weakness.  相似文献

园林景观规划设计与地域文化   总被引:1,自引:0,他引:1  
地域文化的缺失导致园林景观规划设计及其实施效果呈现雷同的趋势,通过提出规划设计中地域文化的范畴和意义,强调了体现地域文化在规划设计中的重要性。借助三个实际的规划设计案例从宏观角度提出规划概念应与地域自然特点、人文特点等要素有机结合,从而从微观角度提出设计可采用保留、抽取、融合、再现等手法来体现地域文化。此外,在规划设计中运用地域文化应该注意契合性、创新性、烂漫性及可实施性等的几个方面的问题。  相似文献

Group concept mapping (GCM) has been successfully employed in program planning and evaluation for over 25 years. The broader set of systems thinking methodologies (of which GCM is one), have only recently found their way into the field. We present an overview of systems thinking emerging from a system dynamics (SD) perspective, and illustrate the potential synergy between GCM and SD. As with GCM, participatory processes are frequently employed when building SD models; however, it can be challenging to engage a large and diverse group of stakeholders in the iterative cycles of divergent thinking and consensus building required, while maintaining a broad perspective on the issue being studied. GCM provides a compelling resource for overcoming this challenge, by richly engaging a diverse set of stakeholders in broad exploration, structuring, and prioritization. SD provides an opportunity to extend GCM findings by embedding constructs in a testable hypothesis (SD model) describing how system structure and changes in constructs affect outcomes over time. SD can be used to simulate the hypothesized dynamics inherent in GCM concept maps. We illustrate the potential of the marriage of these methodologies in a case study of BECOMING, a federally-funded program aimed at strengthening the cross-sector system of care for youth with severe emotional disturbances.  相似文献

ABSTRACT

Low levels of life satisfaction have been linked to low self-esteem and loneliness, but this association has never been tested directly in LGB (lesbian/gay/bisexual) populations. We compared 275 Chinese LGB adults to 275 demographic-matched Chinese heterosexual controls on life satisfaction, self-esteem, and loneliness. LGB adults reported lower levels of self-esteem and higher levels of loneliness than heterosexuals, but similar levels of overall life satisfaction. Self-esteem partially mediated (but did not moderate) the relationship between loneliness and life satisfaction in both groups. Hierarchical regressions indicated that demographic variables, loneliness, and self-esteem can predict life satisfaction in both LGB and heterosexual adults, but explained more variance of life satisfaction in the LGB group. Thus self-esteem and loneliness play a more important role in life satisfaction for LGB rather than heterosexual Chinese adults.  相似文献

在问题类型划分方法的视野下,犯罪概念问题应该属于纯粹刑法学问题中的解释选择问题,但刑法学界以往有关犯罪概念的讨论却大多将其作为刑法问题中的价值判断问题。由于未能妥当确定犯罪概念的问题类型,从而使学界有关犯罪概念的讨论未能达成最低限度的学术共识。作为纯粹刑法学问题中的解释选择问题,形式与实质相结合的混合犯罪概念不存在被替代的必要性,而犯罪概念也不应被规定在刑法典中。  相似文献
