Sexual dysfunction predicts depressive symptoms during the first 2 years postpartum

Background

The association between sexual function and depression has yet to be examined in a prospective cohort study with prolonged postpartum follow-up.

Institutionalizing public relations in China: A sociological analysis of the Chinese Premier's Press Conference

Unlike previous studies that focus on the problems of public relations management, this study tackles the institutionalization of PR in China from a sociological perspective. Through the process of social construction, public relations is institutionalized according to changes in the larger environment, making use of different sources of legitimation. Focusing on the evolution of the Chinese Premier's Press Conference (CPPC), this study finds that the institutionalization of PR in China, especially in the realm of governmental practices, has varied in its structure, settings and contents, which are mixed with informal features within the Chinese social–political context. The CPPC has become a venue for top-down publicity for the powers that be. Because the organizational structure of the CPPC is more centralized than that of other governmental institutions, the form and content of its PR communications are mostly predictable. However, it is the process of the institutionalization of the CPPC that is revealing of how the Chinese government rationalizes its authority and legitimacy.     

创新、升级与培育——2013上海文化消费报告

在全国文化消费方兴未艾的背景下,上海文化消费尤为繁盛。在载体方面,创新与多元化趋势增强。由政府主导的基础型公共文化服务体系进一步完善,消费产品更加多样化,但仍存在公共文化机构数量不足、消费理念薄弱等问题。电影节、书展、动漫节、艺术节、艺博会五大节庆类公共文化平台在消费产品多元化、亲民化、国际化方面的趋势更加明显。新媒体作为市场主导的自主型文化消费载体,发展迅猛。网购、APP、微博经济、网络文学消费稳步增长。在客体方面,假日旅游和出境游消费火爆,私人影院等体验式消费备受青睐,演艺、奢侈品消费呈爆发式增长。在主体方面,上海已形成高、中、低3类消费主体并存的文化消费格局,阶层化倾向日趋明显。     

The stochastic distribution of available coefficient of friction on quarry tiles for human locomotion

The available coefficient of friction (ACOF) for human locomotion is the maximum coefficient of friction that can be supported without a slip at the shoe and floor interface. A statistical model was introduced to estimate the probability of slip by comparing the ACOF with the required coefficient of friction, assuming that both coefficients have stochastic distributions. This paper presents an investigation of the stochastic distributions of the ACOF of quarry tiles under dry, water and glycerol conditions. One hundred friction measurements were performed on a walkway under the surface conditions of dry, water and 45% glycerol concentration. The Kolmogorov-Smirnov goodness-of-fit test was used to determine if the distribution of the ACOF was a good fit with the normal, log-normal and Weibull distributions. The results indicated that the ACOF appears to fit the normal and log-normal distributions better than the Weibull distribution for the water and glycerol conditions. However, no match was found between the distribution of ACOF under the dry condition and any of the three continuous distributions evaluated. Based on limited data, a normal distribution might be more appropriate due to its simplicity, practicality and familiarity among the three distributions evaluated.     

Mental health status of the Hmong Americans in 2011: three decades revisited

This article provides a comprehensive overview of the Hmong in America and encompasses their mental health status for the past 35 years. Since their mass arrival to the United States in 1975, limited research has been compiled to track the specific mental health issues that affect this collective community alone. Major chronological research findings were compiled for this article and specific findings concerning the Hmong and their mental health issues were compared to findings for other Southeast Asian groups. In conclusion, the findings of this article indicate that the Hmong still have higher rates of being diagnosed with depression, the lowest help-seeking behaviors in utilizing Western medicine, and the lowest arithmetic average of "happiness" scaled on an assessment tool. The purpose of this article is to better steer future research projects that entail tracking and differentiating the specific mental health domains of the Hmong.     

公共政策的公平之度:权利平等与特殊保护

与平等不同,公平不是一把单一的尺度,而是对各种平等尺度的权衡。公平所要平衡的最为核心的关系,是权利平等与特殊保护之间的关系。这两种对立要求在经济、社会、政治和文化领域中以各种不同方式表现出来。中国公共政策的公平理念,经历了一个否定之否定的嬗变过程。把握二者关系的公平之度,要遵循边际贡献原则、针对性原则、适度性原则和合作性原则。     

Mortality attributable to obesity among middle-aged adults in the united states

Obesity is considered a major cause of premature mortality and a potential threat to the longstanding secular decline in mortality in the United States. We measure relative and attributable risks associated with obesity among middle-aged adults using data from the Health and Retirement Study (1992–2004). Although class II/III obesity (BMI _ 35.0 kg/m2) increases mortality by 40% in females and 62% in males compared with normal BMI (BMI = 18.5-24.9), class I obesity (BMI = 30.0-34.9) and being overweight (BMI = 25.0-29.9) are not associated with excess mortality. With respect to attributable mortality, class II/III obesity (BMI _ 35.0) is responsible for approximately 4% of deaths among females and 3% of deaths among males. Obesity is often compared with cigarette smoking as a major source of avoidable mortality. Smoking-attributable mortality is much larger in this cohort: about 36% in females and 50% in males. Results are robust to confounding by preexisting diseases, multiple dimensions of socioeconomic status (SES), smoking, and other correlates. These findings challenge the viewpoint that obesity will stem the long-term secular decline in U.S. mortality.     

Strategic altruistic transfers and rent seeking within the family

This paper examines the rent-seeking behavior of “selfish” children in competing for parental transfers. The paper extends Chang and Weisman (South Econ J 71:821–836, 2005), that focuses on compensated transfers, to allow for non-compensated transfers à la Buchanan (J Law Econ 26:71–85, 1983) and derives results for the case in which children’s time contributions as perceived by their parents are a merit good (e.g., service), pure waste (e.g., bugging), or a mix of both. For an increase in the proportion of time contributions that are pure waste, parents find it optimal to reduce the size of an overall transfer, thereby lowering the levels of wasteful rent-seeking activities by their children within the family.
