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.     

China’s flexible overseas food strategy: food trade and agricultural investment between Southeast Asia and China in 1990–2015

Using the UN Comtrade database and multiple sources of agricultural investment data, this paper outlines the emerging patterns of food trade and agricultural investment between Southeast Asian countries and China. The paper shows that China has adopted a flexible overseas food strategy. First, China has increased food export and shifted its food trade with Southeast Asia from a dependent relationship towards a complementary relationship at the regional level in recent years. Second, China tends to adapt to the existing conditions of food production and trade in Southeast Asian countries instead of fundamentally altering them. Finally, Chinese overseas agricultural investment is less driven by domestic food demand but more oriented for profit making, and this gives it flexibility in diversifying investment. An adequate understanding of China’s flexible food strategy in bilateral and multilateral relationships holds implications for global food security.     

Examining multiplicity and dynamics of publics’ crisis narratives with large-scale Twitter data

The new reality of networked publics on social media calls for crisis communication practitioners and researchers to understand the narratives generated by publics on social media during organizational crises. As social media publics possess diverse, unique characteristics and communicative needs during a crisis, they form interpretative communities and co-create various symbolic interpretations of the crisis. Extending the public-centric and narrative perspective to the context of social media crises, we examined what crisis narratives were constructed by social media publics (i.e., multiplicity) and how these narratives changed by crisis stages (i.e., dynamics). Using topic modelling based on large-scale Twitter data of the Chipotle E. coli crisis (N?=?40,610), we identified ten narratives subsumed under two themes (i.e., sharing-based and conversation-based) based on publics’ social constructions of their perceived risks and crisis experience. On the one hand, sharing-based narratives, heavily impacted by publics’ shared media coverage, reflected media crisis narratives and salient risk perceptions aligning with the news agenda. On the other hand, conversation-based narratives, fueled by publics’ opinion expression and emotional venting, demonstrated publics’ interpretations of their experience with the organization in the crisis with less salient but more diversified risk perceptions. Crisis managers are recommended to produce and deliver compelling narratives resonating with different groups of social media publics during crises.

礼萨·汗时期(1921-1941年)伊朗民族国家构建的路径选择与困境

礼萨·汗时期(1921—1941年)是伊朗现代民族国家构建的重要阶段。礼萨·汗通过对各种社会资源的有效整合,建立了一种超越传统部落和宗教权力架构之上的军事、行政和财政主导权,政府成为社会公共权力的中心,扭转了长期以来传统王朝国家的地方主义割据局面,彻底改变了中央与地方的关系。但礼萨·汗"政府主导型"模式的现代化改革在一定程度上激化了国家与社会(部落、什叶派伊斯兰)之间的矛盾,特别是复杂的政教关系和强制性的民族整合政策使伊朗国家构建和民族构建进程陷入困境,极大削弱了巴列维王朝的政治合法性基础。     

大数据背景下网络调查样本的建模推断问题研究——以广义Boosted模型的倾向得分推断为例

随着大数据和网络的不断发展，网络调查越来越广泛，大部分网络调查样本属于非概率样本，难以采用传统的抽样推断理论进行推断，如何解决网络调查样本的推断问题是大数据背景下网络调查发展的迫切需求。本文首次从建模的角度提出了解决该问题的基本思路：一是入样概率的建模推断，可以考虑构建基于机器学习与变量选择的倾向得分模型来估计入样概率推断总体；二是目标变量的建模推断，可以考虑直接对目标变量建立参数、非参数或半参数超总体模型进行估计；三是入样概率与目标变量的双重建模推断，可以考虑进行倾向得分模型与超总体模型的加权估计与混合推断。最后，以基于广义Boosted模型的入样概率建模推断为例演示了具体解决方法。     

移情入“新”梦——中国电影与新生代观众的关系探研

时值"中国电影新力量"初成之际,作为"新力量"重要组成部分的新生代观众群体对这股发展大潮是不可或缺的。新生代观众以80、90后为主,这一代是娱乐化、网络化与个性化的一代。当下中国电影为让新生代观众能够透过影像移情入梦,便依据新生代观众独有的新特性,在复制真实、隐藏真实和制造仿像三个阶段中,充分运用各种艺术与技术的手段来满足他们的观影心理诉求,以保证电影票房的持续增长。
