The reproductive health indices and sex hormone levels in middle-aged and elderly Chinese men

Objective: The aim of this study was to analyze the age-related recession trajectory of reproductive health indices in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County, Zhejiang in 2012. Healthy men between 40 and 80 years of age were considered eligible for the study. Physical examination and the sex hormones were measured. The subjects were assessed based on the 5-item version of the International Index of Erectile Function (IIEF-5) for Erectile Dysfunction (ED), and Aging Males’ Symptoms (AMS) scale for Symptomatic Late-Onset Hypogonadism (SLOH).

Results: TG showed a decrease at age 60 years. Testis volume and TT did not show significant difference among the four age groups; cFT began to decrease at age 50 years and Bio-T decreased faster at age 50 years. SHBG and LH increased faster at age 50 and 70 years, respectively. IIEF5 score decrease faster at age 60 years. AMS scores increased faster at age 70 years. With the increase in age, the symptoms of ED and SLOH became severer.

Conclusion: Different indices on reproductive health of men showed turning points at different ages. At first, androgenic sex hormones decreased faster, and then erectile dysfunction got severer, and the last overall male syndromes declined.     

China and global internet governance: toward an alternative analytical framework

Drawing on historical methods, this study assesses the conventional “cyber-sovereignty” framework, which has been used to capture and interpret China’s stance toward global Internet governance. This framework focuses on political control and tends to reduce China’s policies to the attempts by an authoritarian state to elevate governments and intergovernmental organizations to be the only legitimate governors of global cyberspace. As it traces the evolution of China’s relationship with the global Internet in the past three decades, the study demonstrates that China’s stance is more complex than the prevalent framework allows and that it is both built upon and different from the US-centric, market-oriented Internet governance scheme. This study recognizes the inadequacy of the conventional framework and invokes a theory of critical political economy of communication, thereby offering an alternative model to explicate the complex power dynamics behind China’s changing strategies. The alternative model advanced in this study is based on the understanding of China’s evolving approach as the product of multifaceted interactions among a group of power-holders that include both state agencies and business units on the transnational level.

Co-Occurring Psychosocial Problems and Multiple Sexual Partners among Men Who Have Sex with Men in Shanghai,China: A Syndemic Approach

We aimed to apply syndemic theory to verify the association and reinforcing effects between psychosocial problems and multiple sexual partners (MSP) of men who have sex with men (MSM) in Shanghai, China. A cross-sectional study was conducted among 547 MSM in Shanghai, China using a face-to-face survey. Sociodemographic and psychosocial data were collected, as well as information on MSP and condomless anal sex. In the 6 months prior to the survey, 54.3% of the MSM sample had had MSP. Univariate analysis showed that self-esteem, depression, loneliness, sexual compulsivity, and involuntary subordination (IS) were associated with MSP. Sexual compulsivity (multivariate odds ratio [ORm] = 2.94, 95% CI = 1.76–4.91) and IS (ORm = 1.79, 95% CI = 1.14–2.81) remained significant in multivariate analysis. MSM with five or more psychosocial problems had greater odds of (adjusted odds ratios = 3.06, 95% CI = 1.49–6.25) having MSP in the previous 6 months than the non-syndemic group. Our findings provide preliminary confirmation of the additive relationship of syndemic psychosocial health conditions and MSP among MSM in Shanghai, China. An integrated intervention with special focus on sexual compulsivity and IS is needed.     

Supportive organizational environment,work-life enrichment,trust and turnover intention: A national survey of PRSA membership

Based on an online survey of a national random sample of the PRSA membership (n?=?650), this study is among the first to explore public relations employees’ own turnover intention and propose three contributing factors for employers to keep top talent in PR industry: a family-supportive organizational environment; the positive, enriching impact of professional work upon practitioners’ life; and PR practitioners’ trust toward employers. Theoretical and practical implications are discussed.     

How leader role identity influences the process of leader emergence: A social network analysis

Contemporary theories on leadership development emphasize the importance of having a leader identity in building leadership skills and functioning effectively as leaders. We build on this approach by unpacking the role leader identity plays in the leader emergence process. Taking the perspective that leadership is a dynamic social process between group members, we propose a social network-based process model whereby leader role identity predicts network centrality (i.e., betweenness and indegree), which then contributes to leader emergence. We test our model using a sample of 88 cadets participating in a leadership development training course. In support of our model, cadets who possess a stronger leader role identity at the beginning of the course were more likely to emerge as leaders. However this relationship was only mediated by one form of network centrality, indegree centrality, reflecting one's ability to build relationships within one's group. Implications for research and practice are discussed.     

自我建构对消费者促销方式偏好的影响

  形式多样的促销手段成为企业在激烈市场竞争中赢得胜利的重要方式。已有研究涉及的促销方式直接受益实体都是消费者自身,随着消费者社会责任意识的提高,直接受益实体为慈善机构的捐赠促销活动不断出现,然而很少有学者对不同受益实体的促销方式的效果进行比较。         基于信息框架理论和调节定向理论,以打折促销和捐赠促销为研究对象,运用分类变量中介检验和3阶交互效应方法,通过Spss软件中的Process插件进行Bootstrap中介效应分析,解释调节定向在不同自我建构消费者对两种促销方式偏好关系中的中介作用机制,并引入感知风险和感知稀缺两个变量,探究其在自我建构对消费者促销方式偏好影响中的调节作用。         研究结果表明,调节定向在自我建构与促销方式选择的关系中起中介作用,即拥有独立自我建构的消费者认为促进定向信息说服力更强,从而偏好打折促销方式;拥有依存自我建构的消费者认为防御定向信息说服力更强,从而偏好捐赠促销方式。当感知风险较高时,防御定向信息强化依存自我建构的消费者对捐赠促销方式的偏好;当感知风险较低时,促进定向信息强化独立自我建构的消费者对打折促销方式的偏好。当感知稀缺较高时,防御定向信息强化独立自我建构的消费者对打折促销方式的偏好;当感知稀缺较低时,促进定向信息强化依存自我建构的消费者对捐赠促销方式的偏好。         在理论上拓展了信息框架效应的相关研究,揭示了自我建构与调节定向作用关系的适用边界。通过检验不同自我建构消费者对调节定向相匹配的促销信息评价机制,证明促销活动中的匹配机制可使促销效果更佳。在实践上,为企业在不同消费情景下面对不同特点消费者制定相应的促销活动提供了策略指导,从而提升企业的销售利润。
