Beyond demographic identities and motivation to learn: The effect of organizational identification on diversity training outcomes

There is a pressing need for better explanations of diversity training effectiveness so that organizations can administer training programs that facilitate positive intergroup interactions. In this paper, we consider the unique predictive effect of organizational identification on diversity training outcomes beyond the effects of the traditional predictors of demographic-based identities and motivation to learn across two samples of employees involved in diversity-related training at their employing organizations. Organizational identification predicted unique variance in voluntary participation in diversity training, diversity training-related knowledge application, motivation to transfer diversity training, and diversity training-related organizational citizenship behavior intentions. Research and practitioner implications are discussed based on our findings.     

For the sake of my family: Understanding unethical pro-family behavior in the workplace

Unethical behaviors are prevalent and costly in organizations, and much recent research attention has been paid to different forms of workplace unethical behaviors. We contend that the extant research has overlooked an important form of workplace-related unethical behaviors: unethical behaviors that are conducted to benefit one's family but which violate societal and organizational moral rules, a construct we label as “unethical pro-family behavior” (UPFB). Our paper systematically conceptualizes UPFB and develops a scale for it. Drawing upon social cognitive theory, we argue that employees with stronger family financial pressure are more likely to employ moral disengagement mechanisms to deactivate moral self-regulation, resulting in higher levels of UPFB. Additionally, we argue that the proposed relationship is more pronounced when employees have high family motivation but is mitigated when employees have high organizational identification. Two studies are conducted for this paper. In Study 1 (N = 328 for Sample 1; N = 243 for Sample 2; N = 279 for Sample 3; N = 267 for Sample 4), we demonstrate that our UPFB scale has good construct validity and that our construct is differentiable from relevant constructs. In two time-lagged survey samples in Study 2 (N = 255 for Sample 1; N = 233 for Sample 2), we find support for our hypotheses. Theoretical and practical implications, limitations, and future directions are discussed.     

自我决定理论在环境教育中的应用

自我决定理论指在自我决定的意义上说,行为是主观上自主选择、自主决定的,而不是迫于某种内在需要或外在力量的压力。自我决定动机区分了促进内部动机的社会环境,分别涉及三种不同的心理需要：胜任、自主和关系。三个基本的需要缺一不可,也就是说只有在三个基本心理需要都得到满足时,自我决定动机和自我决定行为才能产生。教师在环境教育课程中运用自我决定理论培养学生环境动机,可采用三种教学策略：获取学校其他教师、行政人员、家长和社会的支持;选择学生感兴趣的,具有挑战性的问题;采用合作学习与探究学习的方式。     

沸石强化生化装置脱氮功能的效果及机理初探

针对石化工业废水开展沸石强化脱氮处理试验研究,通过比较沸石浓度25mg/L与空白,以及沸石浓度25 mg/L与50mg/L两阶段脱氮效果,探讨沸石促进脱氮功能的机理,结果表明,曝气池中投加沸石可明显提高氨氮和总氮的去除率,硝化细菌总数和硝化功能也得到增强。与空白对照组相比, 沸石浓度25mg/L的试验组运行稳定后,氨氮去除率提高约10%~13%,总氮去除率约提高13%,出水中NO3--N含量约提高100%,氨氮与总氮之比下降6%,内源硝化耗氧呼吸速率可提高138%,硝化细菌总数是空白对照组2.2folds。沸石浓度提高到50mg/L后,试验组的脱氮效果略有增加,但效果不明显。通过对试验结果的关联分析,认为沸石提高系统脱氮能力的原因一方面是因为沸石对NH4+及硝态氮的交换吸附,另一方面NH4+离子富集于沸石表面及内部、沸石颗粒独特的好氧-缺氧微环境,以及沸石离解出CO32- 或HCO3-增加碱度等条件,促进了硝化细菌和反硝化细菌的生长,从而提高了系统脱氮能力。     

聚糖原菌富集实验及其内源过程探究

细胞衰减是微生物内源过程的一个重要组成部分,可分为由细胞死亡引起的数量衰减和由细胞活性降低引起的活性衰减两部分.通过挥发性脂肪酸（VFA）吸收速率(VFAUR)测定、荧光原位杂交技术（FISH）以及LIVE/DEAD细胞染色技术,研究了富集聚糖原菌（GAOs）在序批式反应器（SBR）系统中好氧环境下的衰减特征.结果表明,当T=30℃、进料中m(COD)∶m(P)=100时,SBR系统中GAOs富集比例达94%.测定和计算表明,SBR富集系统中GAOs衰减速率和死亡速率分别为0.132 d^-1和0.034 d^-1,其数量衰减和活性衰减占其细胞总衰减比例分别为26%和74%.可见,GAOs数量衰减只占其细胞总衰减中很小一部分,而绝大部分衰减由活性衰减所引起.     

Humanitarians' ethics: the role of face-to-face experiences in humanitarian aid workers' motivation

This paper analyses the significance of specific ethical experiences for humanitarian aid workers' motivation. Following Emmanuel Levinas's understanding of ethics as arising from intersubjective face-to-face encounters, the study illuminates the experiential origins of the humanitarian commitment by analysing James Orbinski's memoir entitled An Imperfect Offering: Dispatches from the Medical Frontline. Orbinski, a former International Council President at Médecins Sans Frontières, was directly involved in humanitarian responses to several major crises during the 1990s, including those in Somalia, Afghanistan, Rwanda, and what was then Zaire. This paper explores three formative experiences from Orbinski's childhood and teenage years to analyse the personal ethics of humanitarian aid workers and to illuminate the intersection of the personal and professional level of humanitarian aid work. Illustrating that Orbinski's humanitarian commitment is a surrendering to the other's call, the paper argues for stronger inclusion of aid workers' lives and experiences to achieve a comprehensive understanding of humanitarian work.     

农作物病虫害专业化防治服务对农药施用强度的影响

农药过量施用已造成严重的负外部性。推行农作物病虫害专业化统防统治服务可以实现安全、科学、合理用药,有效缓解农业面源污染问题和提升食品的质量安全水平。为了探究病虫害专业化统防统治服务在缓解农业面源污染方面的效果,文章利用全国七省水稻病虫害专业化防治服务调查数据,基于倾向得分匹配方法(PSM),剔除样本自选择内生性问题的影响,分析农户将水稻病虫害防治环节外包给植保专业化服务组织("统防统治")与"自防自治"户相比使用农药的种类和施用次数的差异,即植保专业化防治是否取得了较好的环境效应。研究结果表明,植保专业化服务显著减少了农药施用强度,提高了无公害低毒农药的采用比例;并且其效果在小农户和规模种植大户之间存在明显差异,与采纳病虫害统防统治服务的规模种植大户相比,小规模种植户在采纳病虫害统防统治服务后在降低农药施用强度,提高无公害低毒农药的应用比例方面效果更显著。基于此,文章建议强化对植保专业化防治项目的财政扶持力度,提高病虫害专业化防治覆盖率;重点鼓励小规模种植户采纳病虫害统防统治服务;鼓励农户土地流转,促进农业生产规模化经营,加强对种植专业户的病虫害防治方面的培训和引导,并着力发挥专业大户的示范带头作用,提高统防统治的效率,从而促进食品质量安全水平的提升和农业生态环境的保护。     

The affective foundations of high‐reliability organizing

The factors that compel individuals to exert the extraordinary effort needed to create high reliability—consistent error‐free performance under trying conditions—remain unspecified. Here, we propose that when individuals experience emotional ambivalence and prosocial motivation, it induces the broad thinking and other‐orientation that undergird mindful organizing and high reliability.

金盆水库汛期高浊水径流的潜入及热分层水体水质响应

以西安金盆水库为研究对象,在汛期通过对河流区至库区的水温、浊度、DO和营养盐等水质指标进行连续监测,探究降雨径流的潜入规律及热分层水体水质动态响应特性.结果表明:在外界气温变化条件下,水库出现季节性热分层现象.汛期径流的汇入导致下温跃层消亡,热分层稳定性减弱;汛期径流水体携带大量颗粒态营养盐物质和泥沙以异重流形式潜入,其流态从过渡区的底层潜流向主库区间层流转变,潜入初期间层流厚度达20m.降雨早期异重流的潜入导致中下层水体的TN、TP、TOC显著增加,水体平均TN、TP、TOC、浊度最高分别超出平时0.2,2,0.6,16倍,水质呈现短时高污染负荷.底层潜流水体水温较高,大量沉降于沉积物中的颗粒态污染物分解速率加快,內源污染负荷进一步提高,底层水体中TN、TP、TOC浓度高达1.88,0.05,4.6mg/L;汛期可通过分层取水方案和排放高浊水来保障供水安全.
