人才振兴背景下大学生志愿服务乡村缘由和影响因素分析

志愿服务乡村是社会参与人才振兴战略的重要方式,大学生在其中承担着重要角色。“乡愁文化”和“社会理性”是大学生志愿服务乡村缘由所在;性别、年级、学校类型、了解程度和志愿组织对大学生志愿服务乡村有显著影响。大学生志愿服务的着力点在于智力支持且具有文教活动倾向性,但也存在意愿与行动脱节、认知流于表面、能动性不强、缺乏思想引领以及对小微志愿组织的支持缺位等问题。乡愁文化嵌入大学文化、引入激励机制、打造志愿组织“大家庭”、牢守宣传育人“主阵地”、强化智力支持优势、补齐理论技能短板、关爱“小微组织”成长、构建“三位一体”支撑体系等可有效优化大学生志愿服务乡村。     

Improved two-parameter estimators for the negative binomial and Poisson regression models

Negative binomial regression (NBR) and Poisson regression (PR) applications have become very popular in the analysis of count data in recent years. However, if there is a high degree of relationship between the independent variables, the problem of multicollinearity arises in these models. We introduce new two-parameter estimators (TPEs) for the NBR and the PR models by unifying the two-parameter estimator (TPE) of Özkale and Kaç?ranlar [The restricted and unrestricted two-parameter estimators. Commun Stat Theory Methods. 2007;36:2707–2725]. These new estimators are general estimators which include maximum likelihood (ML) estimator, ridge estimator (RE), Liu estimator (LE) and contraction estimator (CE) as special cases. Furthermore, biasing parameters of these estimators are given and a Monte Carlo simulation is done to evaluate the performance of these estimators using mean square error (MSE) criterion. The benefits of the new TPEs are also illustrated in an empirical application. The results show that the new proposed TPEs for the NBR and the PR models are better than the ML estimator, the RE and the LE.     

Kernel density estimation under negative superadditive dependence and its application for real data

In this paper, the kernel density estimator for negatively superadditive dependent random variables is studied. The exponential inequalities and the exponential rate for the kernel estimator of density function with a uniform version, over compact sets are investigated. Also, the optimal bandwidth rate of the estimator is obtained using mean integrated squared error. The results are generalized and used to improve the ones obtained for the case of associated sequences. As an application, FGM sequences that fulfil our assumptions are investigated. Also, the convergence rate of the kernel density estimator is illustrated via a simulation study. Moreover, a real data analysis is presented.     

中国自主品牌形象提升的关键驱动因素及对策研究——基于矫形与塑形传播的视角

提升自主品牌形象是当前改善自主品牌消费环境、扩大自主品牌消费市场的重要现实命题,而厘清自主品牌负面刻板印象生成的根源及影响因素是探讨自主品牌形象提升的关键驱动因素与战略对策的理论基础。首先以8个论坛的受众跟帖为例,运用扎根理论进行探索性研究,发现负面企业形象、负面国货形象、负面政府形象、媒体渲染、国货意识淡漠和社会规范压力等6个主范畴是导致自主品牌负面刻板印象生成的主要影响因素;然后将范畴作为测量问项,将主范畴作为潜变量,进行问卷调查和实证分析,结果表明,6个主范畴均对自主品牌负面刻板印象存在显著的正向影响。在此基础上,根据自主品牌负面刻板印象生成的影响因素,提炼出自主品牌形象提升的5大关键驱动因素,即企业形象驱动因素、政府形象驱动因素、媒介框架驱动因素、消费者情感驱动因素和社会规范驱动因素,并对其影响效应及对策措施进行了探讨,建构了自主品牌形象提升的关键驱动因素影响效应模型。     

Modeling spatial overdispersion via the generalized Waring point process

Modeling spatial overdispersion requires point process models with finite‐dimensional distributions that are overdisperse relative to the Poisson distribution. Fitting such models usually heavily relies on the properties of stationarity, ergodicity, and orderliness. In addition, although processes based on negative binomial finite‐dimensional distributions have been widely considered, they typically fail to simultaneously satisfy the three required properties for fitting. Indeed, it has been conjectured by Diggle and Milne that no negative binomial model can satisfy all three properties. In light of this, we change perspective and construct a new process based on a different overdisperse count model, namely, the generalized Waring (GW) distribution. While comparably tractable and flexible to negative binomial processes, the GW process is shown to possess all required properties and additionally span the negative binomial and Poisson processes as limiting cases. In this sense, the GW process provides an approximate resolution to the conundrum highlighted by Diggle and Milne.     

Leader negative feedback-seeking and leader effectiveness in leader-subordinate relationships: The paradoxical role of subordinate expertise

From a motivational perspective of feedback-seeking behavior, we examined the mediating role of leaders' negative feedback-seeking from subordinates in the relationship between the quality of leader-member exchange (LMX) and subordinates' evaluation of leader effectiveness, along with the moderating role of subordinate expertise in the mediated relationship. Using 151 unique matched sets of leader and subordinate reports obtained from 5 large Korean companies, we found that the positive relationship between LMX and leader effectiveness was mediated by leaders' negative feedback-seeking. Additionally, the positive relationship between LMX and leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. Lastly, the indirect effect of LMX on leader effectiveness through leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. These findings were obtained after controlling for leaders' power distance and goal orientations that might influence their motives to seek or avoid feedback. Theoretical and practical implications are discussed.     

Social capital,guanxi and political influence in Chinese government relations

Social capital has emerged as a promising theoretical approach to understanding political influence in the public relations literature. However, the rationale of using social capital to influence corporate government relations in authoritarian societies is indistinct. To remedy this, we integrate Bourdieu’s (1986) and Lin’s (2001) social capital theories to explore how applying a variant form of social capital (e.g., guanxi) might shape corporate government relations in authoritarian China. A multi-method, qualitative approach was employed involving 44 interviews, participant observation and document review. The findings highlighted an underexamined “vertical” dimension of social capital (i.e., links with authority in a hierarchy), which enables corporations to exercise agency over the pre-existing and often vague regulatory environment. This study adds a new perspective to social capital with hierarchical guanxi that enriches our understanding of guanxi-based political influence in Chinese corporate government relations.     

Family factors associated with emerging adults’ human papillomavirus vaccine behavior

Abstract

Objective: The current study examined the role of family influences on the vaccine behavior of emerging adults. Participants: In Spring 2017, we conducted anonymous online surveys of undergraduate students (n?=?608) at a large, public university in the mid-Atlantic. Methods: Logistic regression was used to examine associations between family factors and students’ awareness of the HPV vaccine, vaccine receipt, and vaccine intentions. Family factors included sex communication, religiosity, parental monitoring, family structure, and parents’ birthplace. Results: More comprehensive family sex communication is associated with less uncertainty regarding HPV vaccine receipt and greater likelihood of being already vaccinated. More frequent family religiosity and more parental monitoring are associated with greater likelihood of having decided against vaccination rather than already being vaccinated. Significant gender and racial disparities exist. Conclusion: Further research, policy, and programmatic intervention are needed to reduce disparities and to improve emerging adults’ compliance with HPV vaccine recommendations.     

Understanding public perceptions of genetically modified organisms in China: The role that heuristics play during digital media exposure

This study explicates the role that heuristics play in influencing Chinese public perceptions of genetically modified organisms (GMO) when they are exposed to digital media. According to the cognitive–affective continuum of heuristics, trust in scientists and negative emotions about GMOs are a cognition-oriented heuristic and an affect heuristic, respectively. The statistical results of an online survey (N?=?414) demonstrated that trust in scientists fully mediated digital media exposure and perceptions of the risks versus benefits of GMOs. In addition, negative emotions moderated the full mediation effect, showing that the indirect effect was stronger in individuals with low levels of negative emotions than in those with high levels of negative emotions. The mediating role of trust in scientists and the moderating role of negative emotions, the two heuristics applied in this study, indicated that when negative emotions were weak, laypeople were more likely to rely on scientists to judge the consequences of GMOs than systematically process the associated information by themselves. The findings have implications for reconsidering the importance of heuristic processing in building reasonable public perceptions of risk-laden technologies through the digital environment.
