基于消费者显著性偏好的双边平台转换成本和定价策略研究

针对消费者对转换成本和价格属性具有显著性偏好的实际情况，基于显著性理论对垄断双边平台企业的转换成本和定价策略问题进行了研究。研究发现：1)在显著性偏好非对称型市场上，对价格敏感的一方收取的价格最低，对高转换成本的一方收取的价格最高，而在显著性偏好对称型市场上，平台的最优价格位于非对称型市场之间，但是对价格敏感型市场收取的价格低于转换成本敏感型市场的价格。2)在高转换成本的市场，平台利润最低；低转换成本市场平台利润最高，而混合型情况的最优利润位于这两者之间。该研究结论说明平台企业应该采取措施来降低用户加入平台的转换成本，从而增加利润，这与现实的案例研究结论相吻合。     

发生主义二语习得观及其应用

发生主义语言观认为,语言是动态的、发展的复杂系统,它采用连接主义的运算工具来建立人类学习机制进行语言习得的模型。文章首先用发生主义和连接主义理性关联学习理论阐释二语习得,然后用注意假设帮助解释二语习得理性关联学习中出现的非理性现象,最后,把上述理论应用到中国环境下的二语习得的实际中,提出重视和提高目标语输入数量和质量、调节二语习得者选择性注意、用目标语语言形式难度预测突显性等建议。

Assessing Politicized Sexual Orientation Identity: Validating the Queer Consciousness Scale

Building on psychological theories of motivation for collective action, we introduce a new individual difference measure of queer consciousness, defined as a politicized collective identity around sexual orientation. The Queer Consciousness Scale (QCS) consists of 12 items measuring five aspects of a politicized queer identity: sense of common fate, power discontent, system blame, collective orientation, and cognitive centrality. In four samples of adult women and men of varied sexual orientations, the QCS showed good test-retest and Cronbach’s reliability and excellent known-groups and predictive validity. Specifically, the QCS was positively correlated with identification as a member of the LGBTQ community, political liberalism, personal political salience, and LGBTQ activism and negatively correlated with right-wing authoritarianism and social dominance orientation. QCS mediated relationships between several individual difference variables and gay rights activism and can be used with both LGBTQ people and allies.     

Social comparison,group identity and professional identity. A study with bank clerks

Abstract

This study consisted of analyzing several hypotheses derived from Tajfel and Turner's social identity theory (Tajfel and Turner, 1979) within a real-life situation. We identified the intergroup relations among three banks in Brazil as an ideal chance to test the salience hypothesis (Oakes & Turner, 1980; Doise & Sinclair, 1973) and also the relationship between discrimination and social identity (Brown et al. 1983b). In general, results did not support the hypotheses, and alternative explanations of results, in terms of the groups ' real life conditions, are discussed.     

Intercandidate agenda-setting in presidential elections: Issue and attribute agendas in the 2004 campaign

This study examined the role of political public relations in the process of intercandidate agenda-setting. Specifically, a content analysis of news releases, political speeches, and issue platform statements was conducted to assess the salience of issues and attributes in the 2004 presidential election from the Bush, Kerry, and Nader campaigns. While modest evidence for intercandidate agenda-setting associations regarding issue salience was obtained, more robust support was detected for attribute salience relationships. In light of these findings, the theoretical and practical implications for political public relations are discussed.     

Family Involvement and Holocaust Salience among Offspring and Grandchildren of Holocaust Survivors

The present research focuses on family involvement reported by offspring and grandchildren of Holocaust survivors (OHS and GHS, respectively). Study 1 included a convenience sample of 75 participants, divided into 2 groups (36 OHS and 39 comparisons). Study 2 included a convenience sample of 92 dyads of OHS and GHS. Both samples completed the Family Involvement Questionnaire and the Holocaust Salience Scale. In line with the hypotheses, Study 1 found that, relative to comparisons, OHS presented greater familial involvement. Only OHS with strong family involvement showed higher Holocaust salience than comparisons. Study 2 showed higher familial involvement among OHS as compared to GHS, and significant parent-child correlations. The results show that family involvement is related to intergenerational transmission of the trauma, especially among OHS. Yet, among OHS and GHS, parents’ and children’s family involvement were associated. The theoretical and practical implications of these findings are discussed.     

The Effects of Death Reminders on Sex Differences in Prejudice Toward Gay Men and Lesbians

Terror management research shows that death reminders (mortality salience) increase prejudice toward worldview violators. Two studies investigated whether death reminders exacerbated differences in heterosexual men's and women's reports of sexual prejudice (negative attitudes based on sexual orientation). Results showed that following death reminders, sex differences in anti-gay discrimination and affective prejudice toward gay men (but not toward lesbians) were larger, and that these increased sex differences were mediated by gender role beliefs. The current studies suggest that researchers may attenuate the effects of death reminders by lessening the perceived worldview violation in addition to alleviating the existential terror of death.     

左向移位结构及其语篇功能的认知理据

左向移位结构又称前置法,是指将句中的某一成分移至句首,而原来的位置则由一代名词来标记的句法结构。左向移位结构有典型的结构和特定的语篇功能。从认知角度看,左向移位结构因信息的突显所致。这一结构的使用突出了移位成分的信息,收到了显著的语境效果。
