An efficient and accurate numerical approximation methodology useful for obtaining the observed information matrix and subsequent asymptotic covariance matrix when fitting models with the EM algorithm is presented. The numerical approximation approach is compared to existing algorithms intended for the same purpose, and the computational benefits and accuracy of this new approach are highlighted. Instructive and real-world examples are included to demonstrate the methodology concretely, properties of the estimator are discussed in detail, and a Monte Carlo simulation study is included to investigate the behaviour of a multi-parameter item response theory model using three competing finite-difference algorithms. 相似文献

Christian Scientists’ rejection of conventional medical practices has generated considerable controversy. Using insights from theories of subcultural identity and cultural repertoires, we analyze elite discourse and adherent narratives from 20 Christian Scientists to examine how this nonmedicalized religion engages the challenges posed by the highly medicalized character of American society. The writings of Christian Science founder Mary Baker Eddy primarily exhibit a critical posture toward conventional medicine, although conciliatory language is also evident in these same works. These discursive nuances provide Christian Science adherents with latitude in negotiating health and illness in their everyday lives. Interview data reveal that negotiated health practices are particularly evident in three domains: using prayer as a means of seeking divine guidance, developing metaphysical competency as a healer, and weighing options based on legal mandates for seeking medical treatment. We conclude by specifying the implications of our findings and identifying directions for future research. 相似文献

This study investigated whether relational uncertainty poses uncertainty threat, which causes compensatory behaviours among Japanese. We hypothesised that Japanese, as collectivists, would perceive relational uncertainty to pose uncertainty threat. In two experiments, we manipulated relational uncertainty, and confirmed that participants exhibited compensatory reactions to reduce aversive feelings due to it. In Study 1, we conducted direct comparison between relational uncertainty, independent self‐uncertainty and control conditions. The results revealed that participants who were instructed to imagine events pertaining to relational uncertainty heightened national identification as compensation than did participants in the control condition, but independent self‐uncertainty did not provoke such effects. In Study 2, we again manipulated relational uncertainty; however, we also manipulated participants' individualism‐collectivism cultural orientation through priming, and the analyses yielded a significant interaction effect between these variables. Relational uncertainty evoked reactive approach motivation, a cause for compensatory behaviours, among participants primed with collectivism, but not for individualism. It was concluded that the effect of uncertainty on compensatory behaviour is influenced by cultural priming, and that relational uncertainty is important to Japanese. 相似文献

Sexual and gender minority (SGM) people are at increased risk for suicidal thoughts and behaviors relative to their cisgender heterosexual peers. However, most research in this area has focused on youth, limiting our understanding of suicide risk among SGM adults. 相似文献

Accused for Involvement in Collective Violence: The Discursive Reconstruction of Agency and Identity by Perpetrators of International Crimes

This study explores discourses about involvement in violent intergroup conflict and international crimes from the perspective of perpetrators. Through a critical discourse analysis of 12 personal interviews carried out with individuals accused by the International Criminal Tribunal for the Former Yugoslavia (ICTY) for crimes committed during the Yugoslav conflicts, we uncover how their discourse reveals conceptions of lacking agency and powerlessness during the conflict, how it reconstructs power relationships within and between ethnic groups, and how it reflects identity management strategies destined to elude blame and responsibility. Our findings demonstrate how discourses are tainted by the legitimizing framework in which the conflict unfolded but also how they are shaped by the particular context of the communicative situation. Findings are discussed in terms of their significance for international criminal justice and its stated objectives. 相似文献

No Postmaterialists in Foxholes: Postmaterialist Values,Nationalism, and National Threat in the People's Republic of China

In this article, I present findings from a survey experiment in which Chinese university students exposed to a treatment designed to increase feelings of national threat were—based on their responses to the four‐item postmaterialism values‐priority battery—significantly more likely to be classified as “pure materialists.” These findings are presented in support of the proposition that perception of a hostile international environment may tend to exaggerate citizens' authoritarian and nationalistic sentiments at the expense of more democratically favorable value orientations. Media and political figures in the West who rail against the evils of China's authoritarian leadership might believe that they are championing and encouraging democratic aspirations among the Chinese people, but might instead be inciting impulses and attitudes that are far less “democracy‐friendly.” 相似文献

Background and Objectives: Basic human values have been categorized into two dimensions: those that are self or agentically focused, and those that are other or communally focused. We apply this model to cognitive appraisals of stress and argue that threat appraisals also fall into these two dimensions. The mediating roles of communal and agentic threats in linking stressors with coping responses were examined. Design: A daily process methodology was used. Methods: Three-hundred and fifty undergraduate students were followed midday and evening over one week, completing structured electronic diaries regarding their experiences of the past half-day. Participants described stressors in open-ended format, which were then coded into social stress, achievement stress, and other stress categories. They also completed scales measuring stress appraisals and coping. Results: Communal threat mediated links between social stressors and empathic responding, support seeking, and confrontation. Agentic threat mediated links between achievement stressors and empathic responding, support seeking, confrontation, and problem solving. Conclusions: Individuals tend to cope in ways that maintain communion when they perceive communion to be threatened; they tend to cope in ways that maintain agency when they perceive agency to be threatened. 相似文献

To identify the boundary conditions for proactive employees making whistle-blowing decisions, we developed a cross-level model comprising employee proactive personality and two types of whistle-blowing intentions that incorporates the influences of organizational- and individual-level attributes. Analyses of data collected from 432 Chinese employees in 32 companies indicated that proactive personality was positively related to internal whistle-blowing intention and even more positively related to external whistle-blowing intention when individuals were working in organizations characterized by an instrumental ethical climate and employees with a high level of moral identity. 相似文献

Abstract : At mid‐century, Harold S. Bender's “The Anabaptist Vision” provided a definition of sixteenth‐century Anabaptist tradition that clarified the self‐understanding of its contemporary Mennonite heirs and by which their faithfulness to the tradition might be judged. Critics of the vision, such as J. Lawrence Burkholder, sought reformulations of the vision's central tension between separation from and integration into “the world,” calling for greater social responsibility and for a recognition that the ambiguities of human existence extend to the church, of necessity qualifying its lived expressions of radical discipleship. 相似文献
