基于社交关系和影响力的在线社交网络用户兴趣偏好获取方法研究

在线社交网络成为人们网络生活的最主要平台,人们基于兴趣偏好等原因集聚形成各个网络社区,共同参与感兴趣话题的讨论,表达自己的观点和看法,寻找感兴趣的内容,因此识别在线社交网络中用户的兴趣偏好,具有重要意义.本文首先分析用户在社交网络中的行为,提出从用户发布信息、基于共同参与话题的社交关系中寻找相似兴趣最近邻,和再考虑用户在社交网络中影响力的相似兴趣最近邻,三种获取用户兴趣偏好的方法.最后利用百度贴吧数据集实验,比较三种方法的使用效果.实验表明考虑用户影响力的最近邻方法获取用户兴趣偏好的方法效果最好,而且这种方法不需要利用用户本身信息,仅仅只需要通过其最近邻用户就可以获得更加准确的用户兴趣偏好.     

基于用户感知、偏好和涉入的微博舆情传播意愿影响因素研究1）

微博舆情的传播主要靠用户来推动。在《解释》出台的背景下,从用户感知、偏好和涉入三方面着手,结合信任因素,构建了影响微博舆情传播意愿的模型,并运用结构方程模型对所构建模型和假设进行了实证研究。研究结果表明,感知风险负向作用于舆情传播意愿,用户涉入及事件关注偏好对舆情传播意愿具有积极影响,而信任信源偏好、感知信息质量则通过影响信任的形成进而对舆情传播意愿产生积极作用,此外,信任负向影响其感知风险。

绩效负向反馈对风险战略行为的影响——股权激励的调节作用

基于认知偏好理论,提出企业绩效负向反馈、股权激励和企业风险战略行为之间的关系假设。在对621份上市公司样本数据进行分析的基础上,得出研究结果:面对绩效的负向反馈,企业会采取规避风险的战略行为;股权激励促使高管认知偏好从风险规避变为风险爱好,当企业采取股权激励时,面对绩效的负向反馈,企业会积极采取风险战略行为。     

Identifying Communities in Need: Examining the Impact of Acculturation on Perceived Discrimination,Social Support,and Coping amongst Racial Minority Members in the United States

Utilizing a cognitive appraisal approach, this study examines how acculturation affects racial minority members' appraisals of and responses to racial discrimination. Racial minority members (N = 345) completed questionnaires about their prior experiences with racial discrimination and coping responses. Controlling for participants' prior experiences with racial discrimination and primary appraisals, the results revealed that acculturation helped explain individuals' need for social support, support message evaluations, and the pursuit of disengagement coping strategies. Findings from this study provide helpful information for the development of intervention and outreach programs for individuals in our communities who are coping with racial discrimination.     

Ethnic categorization of immigrants: The role of prejudice, perceived acculturation strategies and group size

People usually perceive immigrants from different national origins as similar to each other, and thus as belonging to a limited number of ethnic out-groups [Sporer, S. L. (2001a). Recognizing faces of other ethnic groups: An integration of theories. Psychology, Public and Law, 7, 36–97, Sporer, S. L. (2001b). The cross-race effect: Beyond recognition of faces in the laboratory. Psychology, Public Policy and Law, 7, 170–200.]. In this study, we examine how host nationals (i.e., Italians) categorize immigrants and how prejudice and perceived acculturation strategies influence this process. In our research, photographs of male faces of members of 16 immigrant groups were shown to the participants (N=305). They were asked to identify the national origin of each person on the photographs. In line with the expected over-inclusion into more numerous and more devalued out-groups, the researchers found that (a) participants who perceived Albanians or Moroccans to be the most numerous, were most likely to categorize immigrants as belonging to these groups; and (b) this over-inclusion effect was most pronounced when participants were prejudiced toward these groups and when they perceived them as wanting to maintain their cultures of origin.     

Linear and orthogonal models of acculturation and its relations to cultural variables: An examination of the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA)

The Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA) is the most widely used measure of acculturation for Asians. The purpose of the current study was twofold: First, the study explored the consistency of the SL-ASIA in characterizing Asian American men's level of acculturation - Asian-Identified, Western-Identified, Bicultural - using the items of the scale in orthogonal versus linear approaches. Second, the study examined the association between the two scoring methods and characteristics indicative of Asian culture—family allocentrism, loss of face, and affect intensity. An orthogonal approach suggests individuals may identify both with Asian and Western cultures, whereas a linear approach indicates an individual identifies with one culture at the expense of the other (e.g., high Asian, low Western identified). We examined the classification rates of these two methods using a large sample of Asian-American collegiate men (n = 521) and then within each ethnic subgroup of Asian men (e.g., Chinese, Japanese, Korean). Results suggested the two methods of characterizing men consistently diverged. Across the Asian subgroups, the overall agreement rates using linear and orthogonal methods were approximately at chance. Furthermore, significant correlations were observed among acculturation scoring methods and variables indicative of social integrity and family attitude. The implications for these findings and potential future directions for the study of acculturation are discussed.     

Acculturation preferences of majority and minority adolescents in Germany in the context of society and family

Four hundred and fifteen adolescents (134 German majority and 281 minority members) completed a questionnaire which measured attitudes towards acculturation, life satisfaction and intergroup relation variables. German majority members preferred integration followed by assimilation (according to Berry's taxonomy), while minority members had a clear preference for integration. Integration was more strongly associated with favourable intergroup relations and, in the case of minority members, life satisfaction, than the other acculturation orientations. Furthermore the study showed that discrepancies between own acculturation attitudes and perceived attitudes of the other group may influence life satisfaction and intergroup attitudes. Perceived acculturation preferences of the respondents’ parents were also examined. German majority adolescents perceived their parents’ attitudes as more favourable to exclusion than their own, and minority members perceived their parents’ attitudes as leaning more towards separation than their own. In the majority sample, these discrepancies were not related to any of the outcome variables, but in the minority sample they influenced life satisfaction, perceived quality of intergroup relations, and tolerance.

Fitness,Fun and Friends through Participation in Preferred Physical Activities: Achievable for Children with Disabilities?

This study investigates the preferences for actual participation in and enjoyment of physical out-of-school activities in children with physical disabilities, including what particular activities they are actually participating in, how often, with whom, where, and how enjoyable they find these activities. The data are based on structured interviews with 149 children (67 girls (45%) and 82 boys (55%) from 6 to 17 years) who were attending three weeks of intensive rehabilitation at Beitostølen Healthsports Centre in Norway. The Children’s Assessment of Participation and Enjoyment and Preferences for Activities of Children scales were administered at the start of their rehabilitation stays. The study reveals a quite high level of participation in physical activity and a high degree of enjoyment in participating, but the children want to be even more active than they already are. They have clear preferences for activities, and these activities are to a large extent consistent with what they actually do during their leisure time. The children are most frequently active with family members, but they would prefer to be more active with peers. A prerequisite would therefore be to acquire better basic skills and competencies in a few chosen activities rather than having some experiences in a broad range of different activities. There are more similarities than differences between boys and girls and between age groups on the parameters investigated in this study.
