B2C的顾客价值与交易成本并非线性相关

基于市场营销理论,对电子零售业(B2C)中交易成本和顾客价值两个概念进行分析,认为B2C降低交易成本并不一定能提高顾客价值,即并非线性相关。还有一个变量是顾客对交易成本的看重程度,在此基础上提出B2C交易成本与顾客价值关系的模型,并分析了此模型对B2C企业的意义。

综合性大学与医学类院校学生无偿献血的动因比较研究

以南京某综合性大学和某医学院校为例,比较两类学校学生在无偿献血认知、献血参与态度及献血动机方面的差异。通过文献研究、专家咨询及焦点小组评分编制调查问卷。认知差异比较采用卡方检验,态度和动机差异采用t检验。综合性大学学生对无偿献血的认知水平较低。医学类院校学生在献血参与态度方面的得分较高,二者在献血感受上无差异。献血动机方面,医学类院校学生献血的利他性得分较高,在两校暂未献血人群中,医学类院校学生自我效能型和献血奖励型动机得分更高。需加强对综合性大学学生献血知识的普及,根据态度及动机差异采取有针对性的献血宣传及招募。

语言符号的无意识直觉和联想关系——索绪尔手稿研究之一

言说者潜意识的记忆能力或联想能力由各种各样的相似关系唤起.言说者的语言意识一方面是主体对语言符号再现特性的内在反思;另一方面,言说者的语言意识在很大程度上是潜伏的,无意识的.意识的呈现是经由语言和语言结构完成的,我们通过意识反思无意识,也就是说,我们掌握了语言和语言结构,也就掌握了无意识.因此,无意识是通向语言科学的条件.     

Loneliness and Subjective Well-Being Among Chinese Undergraduates: The Mediating Role of Self-Efficacy

Previous studies have shown a negative relationship between loneliness and one’s subjective well-being. However, it has not been fully examined within the Chinese context which highlights the importance of social relationship and interpersonal harmony for one’s life, and the mechanism between them has not been thoroughly explored. Based on social cognitive theory, this study examined the main effects of loneliness on individuals’ stress, depression, and life satisfaction, as well as the mediating effect of self-efficacy between them. Survey data were obtained from 444 Chinese undergraduates. The results of multiple regressions revealed that loneliness was negatively correlated with life satisfaction and positively correlated with stress and depression. Moreover, self-efficacy partially mediated the relationship between loneliness and stress, as well as depression, and fully mediated the relationship between loneliness and life satisfaction. Implications for research and practice are discussed.

A transnational networked public sphere of air pollution: analysis of a Twitter network of PM2.5 from the risk society perspective

ABSTRACT

Drawing on digitaltrace data, publicly accessible government documents, and journalistic reports, this research integrates Beck’s risk society theory with digital media theories to examine the mediated process of risk definition and assessment of PM2.5 (particulate matters with a diameter less than 2.5 micrometers) in a networked public sphere. Network and content analysis of a PM2.5 Twitter network shows that political and professional elite remained the most powerful producers of risk definition. Established media played a key role, yet faced challenges from a variety of actors who disseminated and filtered information. Laypersons, while peripheral, actively interacted with elite and established media. The blurring geographic boundary in the PM2.5 Twitter network revealed an emerging transnational public sphere, which, however, was segregated by language. This research advances a layered understanding of the contingent, paradoxical media impact for social changes in a risk society.     

Challenges in Meeting the Mental Health Needs of Urban Asian American Adolescents: Service Providers’ Perspectives

Although Asian American youth are often viewed as the model minority group who are doing well, research with youths, parents, and school personnel have documented significant unmet mental health needs among this population. However, little is known about the perspectives of service providers who work with Asian American youth in afterschool and mental health care settings with respect to what they perceive as challenges meeting the psychosocial needs of the population. The current exploratory study used Consensual Qualitative Research to analyze in-depth interviews with mental health providers, educators, and advocates working with Asian American youths in a multiethnic large urban environment. Results found that service providers were attuned to the multiple needs of the community but also spoke of challenges in meeting basic and psychological needs due to difficult family dynamics, structural stressors (e.g., economic and legal), and societal stigma and discrimination. We draw implications for providing more integrated services across different levels of urban Asian American adolescents’ ecological system to better meet the psychosocial challenges facing this population.     

“三元”知识的运作管理模式:理论与应用

"三元"知识理论的提出是管理史上一次突破性的进展,但这一理论及其应用是尚未受到充分研究的管理领域。依据感性知识、理性知识和活性知识的基本分野与关联,构建起一个"三元"知识的运作管理模式:以操作与实践为支柱、以战略与制度为后盾、以价值观与理想为动力。这一管理模式在人力资源管理、知识管理和战略管理领域有着巨大的应用价值,而且,"三元"知识运作管理模式蕴涵的批判性学习较之于其他学习方式更胜一筹。
