养老保险体系的两种模式与社会经济因素关系比较分析 总被引:1,自引:0,他引:1
本文分析了现收现付和基金积累两种不同养老保险模式与人口老龄化、社会经济增长、通货膨胀、储蓄等社会经济因素之间的关系。经济的增长情况以不同的方式对现收现付模式和基金积累模式产生影响:对现收现付模式来说,如果经济增长缓慢,未来就业者的养老金负担就会增加,其效果与老龄人口在总人口中的比重增大一样;对于基金积累模式而言,如果经济的增长缓慢,那么在长时期内,利率就会处于一个相对较低的水平,这是不利于养老基金的有效增值,未来退休者的养老金收益就会减少。与现收现付模式相比,基金积累模式能带来一个更高的储蓄水平。 相似文献

Objective: To understand how the Greek system uniquely influences smoking attitudes, beliefs, and behaviors among college students who belong to a social sorority or fraternity. Participants: Active members of sororities (n = 16) and fraternities (n = 17) were interviewed between February 2013 and October 2015. Methods: In-depth interviews were conducted examining the social influences of the Greek system on member smoking. Transcribed interviews were coded and analyzed for themes. Results: Sorority and fraternity members experienced different social influences on smoking. Sorority stigmatization of smoking outside bars or parties caused sorority members to hide their smoking. Fraternity members had no social penalties for smoking and allowed smoking at the fraternity house. Fraternity members influenced both fraternity members and sorority members to smoke by sharing cigarettes and smoking at parties. Conclusions: Sororities and fraternities have created social environments that both promote smoking and stigmatize it, presenting unique challenges in college student smoking prevention and cessation efforts. 相似文献

自新增长理论形成以来,将养老保障制度与人力资本积累相联系进行研究成为社会保障、社会学等领域的研究热点之一。无论是国外的理论研究还是实证研究均表明,养老保障制度对于人力资本积累的影响作用是十分明显的。但我国目前理论界直接对养老保障制度与人力资本积累之间关系展开研究的尚属少数。因此,关于养老保障制度对家庭人力资本积累的影响研究的广度和深度均有待发掘。 相似文献

Objective: Despite declining cigarette smoking rates in the US, there is a continued need for tobacco prevention education campaigns to reach young adults. Recognizing the need for improved tobacco control messaging, the University of Texas (UT) System engaged The University of Texas at Austin Center for Health Communication to develop a brand and message that would strengthen tobacco control efforts at its 14 institutions. Methods: This article describes the iterative process involved in creating a brand for tobacco control, including an environmental scan, identifying potential message themes, and creating and refining logos. Results: This article highlights the process of developing a system-wide tobacco control brand. Specifically, the process included coordinating an interdisciplinary team with content and design experts, and presenting ideas to stakeholders for serial feedback and refinement, among others. Conclusions: Ultimately, this project offers a model for other systems of higher education interested in pursuing similar initiatives. 相似文献

The United Nations Millennium Development Goals (MDGs) are unlikely to be achieved by 2015, owing to conceptual flaws in their design as well as the structural and political constraints faced during implementation at the country level. While criticism of the MDGs is widespread, innovative ideas on addressing these operational challenges are still scanty. By reviewing a number of experiences, including those of the Foundation for the Promotion of Local Development (PRODEL) in Nicaragua and the Ministry of Cities in Brazil, this article highlights the importance of incorporating an asset‐accumulation perspective into MDG‐related policies and programmes as a way of generating an enabling environment that opens up new opportunities for poverty reduction in the cities of low‐ and middle‐low‐income countries. 相似文献

This paper provides a response to the commentary by Delfabbro and King (2017), which describes major criticisms of articles situated in a ‘political economy’ conceptual framework. The current paper argues that these criticisms obfuscate legitimate concerns about industry involvement in gambling research, and disregard important evidence about activities of hazardous-consumption industries which provide grounds for strong concern about commercial practices of the gambling industry. Although many aspects of the commentary by Delfabbro and King (2017) are contentious, the current paper summarizes conceptual and empirical literature which supports concern about (a) agency and collaboration in practices of the gambling industry, which make assertions of equivalence with a conspiracy theory both inappropriate and misleading, and (b) the role of research on problem gambling behaviours and pathologies in supporting agendas that may undermine public health. This indicates the need for the scientific community to take seriously its role in improving awareness of the hazards of commercial involvement in gambling research, and thus helping researchers to make informed decisions about these risks and their own manner of engagement with the gambling industry. 相似文献
