"非典"重大突发公共卫生事件的思考

“非典”属于重大突发公共卫生事件,它不仅是卫生部门的事情,而且环保、公安等部门都兼负有责任。在抗击“非典”的过程中,我国政府在各方面都做出很大的努力,也取得了明显的效果。《突发公共卫生事件应急条例》的颁布,标志着我国进一步将突发公共卫生事件应急处理工作纳入法制的轨道,将促使我国突发事件应急处理机制的建立和完善。     

群体性事件形成的心理机制分析

我国正处在社会转型时期,由各利益主体之间的磨擦而引发的群体性事件日益增多,诱发群体性事件的原因也复杂多样。如果从人类行为发生的内在机理看,它们主要遵循刺激——反应机制。导致群体性事件的发生既有直接诱因,也包括弱势群体的大量存在等社会诱因,而各种认识的偏差则是群体性事件的主观心理性因素。我们只有通过改变条件或作用方式,正确调整社会心理,使群体性事件丧失其发生的前提,才能达到预警预防群体性事件的目的。     

High risk factors of hostage barricade incidents in a Japanese sample

Hostage taking incidents in which the police besiege a particular location are known as hostage barricade incidents. The first aim of the present article was to examine the process of risk assessment in hostage incidents, using a group of police officers as the sample. The second aim was to identify the risk factors involved in hostage incidents and examine the degree of concordance between the risk as assessed by the police officers and the figures obtained from the analysis of actual hostage barricade incidents. For the purpose of this study, a survey was carried out across Japan, and 45 police officers responsible for hostage negotiation responded to the questionnaires. Additionally, a sample of 116 actual hostage barricade incidents that occurred in Japan from 1970 to 2002 was utilised to examine the high risk factors involved in such cases. As per the results, a majority of the police officers (73.3%), in response to an open‐ended question, indicated that the highly excited state of the hostage takers was dangerous for the hostages. Moreover, it was demonstrated in all 116 incidents that several factors such as ‘a long siege’ tended to increase the risk of deaths, though this was very rare (n = 4). On the other hand, the proportion of injuries to the hostages was high in expressive situations such as domestic situations or suicide attempt scenarios. On the whole, the results obtained from the analyses of actual incidents were consistent with those obtained from the police officers' risk assessment in many respects. However, the correlation between the degree of risk as assessed by the police officers and the actual rate of deaths/injuries to the hostages was very low.

Mental architectures with selectively influenced but stochastically interdependent components

The way external factors influence distribution functions for the overall time required to perform a mental task (such as responding to a stimulus, or solving a problem) may be informative as to the underlying mental architecture, the hypothetical network of interconnected processes some of which are selectively influenced by some of the external factors. Under the assumption that all processes contributing to the overall performance time are stochastically independent, several basic results have been previously established. These results relate patterns of response time distribution functions produced by manipulating external factors to such questions as whether the hypothetical constituent processes in the mental architecture enter AND gates or OR gates, and whether pairs of processes are sequential or concurrent. The present study shows that all these results are also valid for stochastically interdependent component times, provided the selective dependence of these components upon external factors is understood within the framework of a recently proposed theory of selective influence. According to this theory each component is representable as a function of three arguments: the factor set selectively influencing it, a component-specific source of randomness, and a source of randomness shared by all the components.     

Recognition bias for critical faces in social phobia: a replication and extension

Studies using linguistic stimuli have provided little support for explicit memory biases among individuals with social phobia (SP). However, using facial stimuli rated on their criticalness, Lundh and Ost (1996) found that individuals with SP recognized more critical than accepting faces, whereas non-anxious controls tended to show the opposite pattern. Since the publication of Lundh and Ost's findings, additional studies using a variety of facial stimuli have produced inconsistent findings (J. Anxiety Disord. 14 (2000) 501; Behav. Res. Ther. 39 (2001) 967). Unfortunately, these inconsistencies are difficult to reconcile given great variation in methods and stimuli. Therefore, we designed a study to replicate and extend the work of Lundh and Ost (Behav. Res. Ther. 34 (1996) 787). Similar to Lundh and Ost, individuals with SP identified a significantly higher proportion of old critical faces as old than did non-anxious controls. Further, extending the work of Lundh and Ost, signal detection analyses revealed group differences on response bias according to face type. Specifically, controls showed a response bias towards indicating that accepting faces were previously seen, whereas individuals with SP did not. Finally, signal detection analyses failed to reveal group differences in the accuracy of memory.     

Toward a Science of Transdisciplinary Action Research

This paper offers a conceptual framework for establishing a science of transdisciplinary action research. Lewin's (1951) concept of action research highlights the scientific and societal value of translating psychological research into community problem-solving strategies. Implicit in Lewin's formulation is the importance of achieving effective collaboration among behavioral researchers, community members and policy makers. The present analysis builds on Lewin's analysis by outlining programmatic directions for the scientific study of transdisciplinary research and community action. Three types of collaboration, and the contextual circumstances that facilitate or hinder them, are examined: (1) collaboration among scholars representing different disciplines; (2) collaboration among researchers from multiple fields and community practitioners representing diverse professional and lay perspectives; and (3) collaboration among community organizations across local, state, national, and international levels. In the present analysis, transdisciplinary action research is viewed as a topic of scientific study in its own right to achieve a more complete understanding of prior collaborations and to identify strategies for refining and sustaining future collaborations (and their intended outcomes) among researchers, community members and organizations.     

Regional grey matter volume in the posterior cingulate cortex predicts positive risk-taking: A moderation model

Positive risk-taking is a crucial element of individual creativity and social development. However, little is known regarding the relation between individual neural differences and positive risk-taking. In addition, critical thinking (CT) and gender have been proven to be two important individual-specific factors associated with risk-taking behaviour, and different levels of CT and gender may have diverse effects on the relationship between brain structure and positive risk-taking. The present study examined the relationship between positive risk-taking and regional grey matter volume (rGMV) in 292 healthy participants. The results showed that positive risk-taking was significantly positively associated with the rGMV of the posterior cingulate cortex (PCC). In addition, this study investigated individual differences in critical thinking and found that it moderated the relationship between rGMV and positive risk-taking. Individuals with lower CT had a stronger association between rGMV and positive risk-taking. Further analysis showed that for males, a greater rGMV was significantly linked to higher positive risk-taking tendency. These findings suggest that PCC evaluates risk and serves as a behavioural adaptation hub for positive risk-taking. This study thereby contributes to the literature on individual differences in brain structure and risk-taking by elucidating the moderating effects of CT and gender in healthy adults.     

Evangelical Civil War on the College Campus,White Evangelical Right Framing Resistance to Racial Justice in 2020s America

This paper examines a civil war brewing among evangelicals on the college campus over racial justice—calls for greater racial equality, equity, and inclusion—in the era of Black Lives Matter (BLM). It examines how the white evangelical right are framing their resistance to racial justice and redrawing the color line in the contemporary college evangelical landscape not with distant “social justice warriors” in broader secular society, but with those right inside their evangelical community who, at varying levels, are coming out in support for racial justice in 2020s America. To do this, I first examine the varied campus evangelicals that support racial justice and how they express and frame their support as proper religious practice. I then explicate how the white evangelical right utilize a strategy of colorblind-othering to fight against these co-evangelicals that support racial justice. Data for the study come from the Landscape Study of Chaplaincy and Campus Ministry (2019–22).     

Development of students’ knowledge about didactics during their first year of the master’s programme in didactics

In this study, I reflect critically on my own experiences as a university teacher of students’ expressed knowledge about the academic subject of didactics at the beginning and end of their first semester as students in the Master’s Programme in Didactics. My reflections are made using a phenomenographic approach to learning, which regards learning as a qualitatively deeper and different way of understanding content. The results of the study are expected to deepen my understanding of knowledge expressed about didactics in two different student groups, and give insight on what is critical for knowledge development in higher education. The first course design consisted of 12 lectures in total by 12 different teachers representing different fields of didactics, such as general didactics and subject-based didactics in different specializations. The second course design consisted of eight seminars where course literature about didactics was discussed, together with three seminars in smaller groups wherein the students in each specialization of didactics met. A comparison between the groups is made, based on a qualitative analysis of the responses on an open question before and after the first semester forms the basis of my own reflections. The analysis aims to establish in what way the students’ explanations of didactics might have changed during the courses, and if there are differences in this development which could be explained by differences in course design. In the first student group, 10 students (in-service teachers) answered both questionnaires, and 11 students in the second group answered both questionnaires.     

Critical reflection: scaffolding social responsiveness for first-year students

The teaching and assessment of socially responsive critical reflection in higher education is challenging, especially when learning does not take place in wider social or practice-based contexts. For many students, learning to reflect on others’ experiences in a socially responsive way requires scaffolding. This paper reports on discourses of self and other in the guided summative reflections of first-year non-clinical health students (n = 23) undertaking activities aimed at increasing social responsiveness. The reflections predominantly featured discourses of self, and the corresponding discourse of others as similar to self. Critical reflection, while infrequent, was usually associated with the less common discourse of others as unlike self. Social responsibility, an even less frequent discourse, was unrelated to self. The findings confirm the need for scaffolding of critical reflection, but also suggest that more course content involvement in others’ lived experiences is pivotal to socially responsive reflection. Further research on effective socially responsive learning and whether it influences later practice is needed.
