分析Chiral分层媒质特性的一般方法(英文)

提出了一套系统方法用于求解任意导体片位于界面的Chiral分层媒质的谐振频率,衰减因子和电磁场分布。文中的分析是在Fourier变换域的并矢格林函数和矩阵分析的基础上来进行的,给出的公式的最大价值在于它提供了求解Chiral分层媒质问题的方法论。     

大学生的心态状况调查及其积极心态培养对策研究

文章利用一般自我效能感量表和简易应对方式量表,对某校大学生作抽样调查,结果显示:不同性别和专业的大学生在自我效能感和应对方式上无显著差异;大学生自我效能感的来源存在偏差,主导性的应对方式也有错位。这表明当代大学生的心态并非都是积极的。因此,高校思想政治工作者要高度关注和研究大学生的心态问题,要培养大学生基于能力的自我效能感,要形成以行动为主导的应对方式,要建立起积极心态培训机制。     

The influence of risk and protective factors on burnout experienced by those who work with maltreated children

The aim of the study was to explore the degree (and type) of burnout and trauma symptoms, personal histories and coping strategies retrospectively reported by those who work with maltreated children and their families. A self‐selected sample of workers (N = 44) completed a self‐report questionnaire assessing childhood maltreatment, family background characteristics, current adjustment, coping strategies and burnout. Workers reported high levels of emotional exhaustion and depersonalization, and a low to moderate sense of personal accomplishment. Family background characteristics predicted the occurrence of maltreatment and current adjustment, and a personal history of maltreatment predicted current trauma symptoms, but not burnout. Workers most frequently used problem‐focused coping strategies and sought social support; however, coping strategies were not associated with the level of either trauma symptoms or burnout. Despite employing positive coping strategies, their efficacy may be affected by other interpersonal, intra‐individual and job resource issues. Copyright © 2002 John Wiley & Sons, Ltd.     

The availability of personal and external coping resources: Thier impact on job stress and employee attitudes during organizational restructuring

This study examines the relationships among personal coping resources, social support, external coping resources, job stressors and job strains in a sample of 110 American Telephone and Telegraph employees undergoing a major organizational restructuring. The study expanded on a model suggested by Ashford (1988) by defining another category of coping resources that employees may draw upon to deal with the stressors and strains which occur during major organizational changes. External coping resources were defined as those which provided employees with a sense of 'vicarious control' in stressful situations. Results indicated that personal coping resources, social support and external coping resources had a direct effect upon job stressor and strain levels. No 'buffering' effect of these coplng resources was found. Hierarchical regression analyses indicated that external coping resources added to the prediction of job stressors and strains even when pertonal coping resources and social support were entered first into the prediction questions.

数字技术对文化产业内容生产的挑战及其应对策略

数字技术当前深度参与文化产业的内容生产,对创作群体、生产活动、传播形式和消费语境等多方面皆产生重大影响,形成了全新的数字文化产业生态。然而,有些数字文化产品过于强调技术而忽视文化的特殊性,导致出现内容生产粗糙随意、价值判断标准矮化、意识形态风险增加等问题,不能稳定地输出品位高、社会效益佳的文化产品,未来发展面临挑战。对此,数字文化产业的内容生产需要打破“注意力经济”的单一模式、改良人工智能算法的激励与推荐机制、探索文化生产评价标准的自我更新,从而推动新时代数字文化产业的高质量发展。     

水库移民分享水电工程效益的制度逻辑、 实践困境及破解之道

水库移民分享水电工程效益旨在促成显性工程效益和隐性发展机遇实现跨地域、跨组织、跨主体的公平配置。 作为水库移民的应然权利,利益分享既符合公正补偿的制度逻辑,更彰显共商共建共赢的发展理念,但目前补偿救济色彩较重、市场导向偏弱,并存在后靠移民发展权利及机遇隐性被动减损、外迁移民脱嵌于迁出地及受益地发展红利、非农移民缺乏系统保障等实践困境,其原因在于水电工程综合效益量化难度大、参与主体关系地位不对等、执行管理机构人员配置短缺。 因此应健全水电工程效益分享协同管理机制,鼓励水电企业履行社会责任,优先助力贫困水库移民脱贫,灵活渐进地实现水库移民分享工程效益实践机制的稳步定型和有序推广。     

Disclosure Stress,Social Support,and Depressive Symptoms Among Cisgender Bisexual Youth

Bisexual youth are at elevated risk for depression when compared with lesbians and gay men. Research on bisexual stigma suggests that these youth are uniquely vulnerable to stress related to sexual identity disclosure. Depression associated with this stress may be buffered by social support from parents and friends. We examined the differential influence of social support from parents and friends (Child and Adolescent Social Support Scale) on the relation between disclosure stress (LGBTQ Coming Out Stress Scale) and depressive symptoms (Beck Depression Inventory) and differences by gender in a sample of cisgender bisexual youth (N = 383) using structural equation modeling. Parental support buffered the association between stressful disclosure to family and depressive symptoms, especially for bisexual men; bisexual women seemed not to benefit from such support when disclosure stress was high. This nuanced examination elucidates the ways family members and clinicians can best support bisexual youth sexual identity disclosure.     

College students coping with interpersonal stress: Examining a control-based model of coping

Objective: The ways that college students cope with stress, particularly interpersonal stress, may be a critical factor in determining which students are at risk for impairing mental health disorders. Using a control-based model of coping, the present study examined associations between interpersonal stress, coping strategies, and symptoms. Participants: A total of 135 undergraduate students from 2 universities. Methods: Interpersonal stress, coping strategies, depression, anxiety, and somatization were assessed via self-report. Results: Students reporting more interpersonal stress reported more depression, anxiety, and somatization, and they reported less use of engagement coping strategies and greater use of disengagement coping strategies. Engagement coping strategies accounted for a significant portion of the association between interpersonal stress and mental health symptoms. Unexpectedly, coping strategies did not moderate the association between stress and mental health symptoms. Conclusion: Interventions designed to improve students' coping strategies may be an effective way to reduce mental health problems on college campuses.
