Divorce and the Divine: The Role of Spirituality in Adjustment to Divorce

This study examined the role of three spiritual responses to divorce for psychological adjustment: appraising the event as a sacred loss/desecration, engaging in adaptive spiritual coping, and experiencing spiritual struggles. A sample of 100 adults (55% female) was recruited through public divorce records. Most appraised their divorce as a sacred loss/desecration (74%), experienced spiritual struggles (78%), and engaged in adaptive spiritual coping (88%). Appraisals of sacred loss/desecration and spiritual struggles were tied to higher levels of depression. Adaptive spiritual coping was tied to greater posttraumatic growth. Spiritual coping and struggles each contributed uniquely to adjustment beyond parallel forms of nonspiritual coping and struggles and mediated links between viewing the divorce as a sacred loss/desecration and depression.     

The Impact of Flexible Working Arrangements on Work–life Conflict and Work Pressure in Ireland

Recent rapid economic growth in Ireland has been accompanied by a strong surge in the number of women in employment, and this has led to a significant increase in the proportion of dual‐earner families. These changes have brought the issue of reconciliation between work and care commitments to the fore. Flexible working arrangements in firms have been identified as one important means of balancing work and other commitments. In this article we investigate the relationship between four flexible working arrangements; flexitime, part‐time hours, working from home and job sharing, and two key employee outcomes; work pressure and work–life conflict, using data from the first national survey of employees in Ireland in 2003. Our results show that while part‐time work and flexitime tend to reduce work pressure and work–life conflict, working from home is associated with greater levels of both work pressure and work–life conflict. We conclude that it is important to distinguish between flexible working arrangements to discover their potential for reducing work pressure and work–life conflict.     

位移边界对2D-FGM板热应力影响研究

考虑不同的位移边界条件,建立了常物性2D-FGM板研究模型,并采用有限元法,得到其冷却瞬态热应力场分布图形。位移边界条件对常物性2D-FGM平面区域冷却瞬态热应力分布影响颇大,在简支和一端固定情况下,2D-FGM板自由边界上的热应力σ_x=0;两端固定情况下,其左右两边界均形成上中下三个应力聚集,应力分布形状和数值都发生了巨大的变化;将四周均设置呈固定约束后,热应力数值增长幅度较两端固定情况时更为明显。此结果为该材料的设计、制备提供了准确的理论计算依据。

自我效能感与工作资源匹配模型的实证研究——对工作要求—资源模型的扩展

工作要求—资源模型的缓压效应受到组织与学者的关注,文章就该模型以压力主体无差异性为前提下实证结果的不一致性,引入个体能力信念变量——自我效能感,从个体与环境匹配的角度,提出自我效能感与工作资源的匹配,扩展工作要求—资源模型。问卷分析结果显示,自我效能感与工作资源对工作要求与工作压力关系的联合调节效应显著,进而得出以下结论:高自我效能感员工有能力且有意愿利用丰富的工作资源积极应对压力刺激;低自我效能感员工对自身能力缺乏信心且态度消极,在低工作资源情境即组织对工作资源代为控制下,更能有效缓解压力刺激。     

论压力管理

压力给很多个人生活、学校发展及社会和谐造成了很大的负面影响。结合自身在从事科研工作中对工作压力的切身体会,从心理学、管理学及行为组织学角度深层次解析了压力的本质及如何管理压力问题。适度的压力对学习起到积极作用,过高的压力对学习起到消极作用。压力产生的本质是学校要求高于学生个体学校适应能力时产生的一种心理活动和体验。提高学生个人学校适应能力可增强学生个人承受学业压力的能力。     

教师工作压力管理的心理学策略

角色过载让科学知识的传播者、思想教育的开拓者一教师--承受了许多外显和内隐压力,甚至压得他们不能喘息,这与"和谐社会"的理念、创造"和谐生命"的思想是不相容的,因此,缓解他们的压力迫在眉睫.基于此,本文试图探讨教师的压力来源、成因,提出缓解压力的心理学干预措施.     

京津冀生态环境建设：现状、问题与应对

以一座钢管混凝土连续梁拱组合单线铁路桥为工程背景,采用先整体后局部的两步分析法,首先利用Midas/Civil软件建立全桥有限元模型,计算拱肋安装及后续施工阶段结构的受力状态,得到局部模型的力边界条件;然后利用ANSYS软件建立拱脚结点局部有限元模型,分析施工期间拱脚结点的局部应力分布规律和应力集中程度;最后将拱脚结点应力计算值与实测值进行比较。结果表明,拱肋与梁体间传力顺畅,拱脚混凝土基本处于受压状态;拱脚内侧与箱梁顶板交界处应力集中现象较明显;拱脚上部拱肋周围、拱脚前脚趾处及两拱脚之间箱梁顶板的局部区域出现较大的拉应力,建议在同类桥梁的设计中加强这些部位的构造措施和配筋。拱脚结点应力计算值与实测值比较接近,说明用实体有限元模型计算的局部应力是可靠的,可用于设计验算。     

壳聚糖对沿阶草叶片抗渗透胁迫的影响

在20%PEG-6000渗透胁迫下,用不同浓度的壳聚糖对离体沿阶草(Ophiopogon bodinieri Levl)离体叶片处理12 h后,测定其相对含水量、叶绿素含量、过氧化物酶活性和脯氨酸含量.结果表明,渗透胁迫下,壳聚糖可减缓叶片中水分的丧失以及叶绿素含量的下降,并能提高过氧化物酶活性和增加脯氨酸含量,这些研究表明壳聚糖能有效缓解渗透胁迫对植物的伤害,提高植物的抗旱性.
