Antecedents and consequences of satisfaction with work–family balance: A moderating role of perceived insider status

This study developed a moderated mediation model to investigate how family‐supportive paid leave and supervision affect employees' satisfaction with work–family balance and in turn their affective organizational commitment and supervisor‐directed organizational citizenship behavior depending on their perceived insider status in the organization. Our analysis of data collected from 118 employee–supervisor dyads in Korean organizations revealed that satisfaction with work–family balance mediated the linkages from family‐supportive supervision to affective organizational commitment and supervisor‐directed organizational citizenship behavior, and the linkage from family‐supportive paid leave to affective organizational commitment. Results further showed that the entire mediational process for family‐supportive supervision was more pronounced for those who perceived themselves to be an insider of their organizations, while the same pattern was not found for the meditational process related to family‐supportive paid leave. Our findings provide theoretical implications for work–family balance research and offer practical suggestions to make employees satisfied with work–family balance.     

Characteristics of fear of crime in evacuation shelters after the Great East Japan Earthquake

After the Great East Japan Earthquake in March 2011, numerous evacuees had to stay in evacuation shelters such as school gymnasiums. In general, after a disaster, ensuring the safety and security of evacuees in evacuation shelters is a serious problem. Consequently, many of these evacuees feared that they would be victims of crime in the shelters or that their evacuated homes would be burgled. To examine what factors evoke a general fear of crime in shelters and burglary of evacuated homes, we conducted an online questionnaire on 300 evacuees in Miyagi Prefecture who had stayed at such shelters. From a factor analysis of fear of 16 specific kinds of crime in shelters, we extracted two factors representing fear of property and female-related crime. We then found that a general fear of crime in shelters was associated with being young and a fear of female-related crime, while a fear of burglary of evacuated homes was associated with being female, owning a detached house, and fear of property crime. Based on these results, we provide recommendations aiming to help reduce the fear of crime in shelters and burglary of evacuated homes.     

关于计划生育“难”的思考

计划生育是“天下第一难的事”,这是有一定道理的。但是,计划生育之“难”的原因?却很少有人专门研究或探及。本文试图通过计划生育工作实践,从宏观上对此做一点探讨,以便在改革开放的大潮中,进一步抓住控制人口的主要矛盾。把握规律,针对问题,采取对策,做好工作,为促进改革开放、发展经济创造良好的人口环境。     

殡仪馆环境污染物分析

殡仪馆存在的环境污染问题日益受到公众和环保工作者的重视,其中以空气中存在的致病菌和遗体火化产生的废气为主.监测殡仪馆环境中存在的细菌总数以及遗体火化所排放的NOx,SO2,CO等污染物,并对采取控制措施前后的监测值进行对比,为治理殡仪馆环境污染,保护殡葬职工和死者家属的健康提供了科学依据.     

瘤胃微生物强化醋糟厌氧消化及其机制

针对醋糟中木质纤维素利用效率低的问题,通过接种瘤胃微生物可强化木质纤维素水解.采用逐步提升体系有机负荷的方式,考察瘤胃微生物生物强化对醋糟厌氧消化性能的提升效果,并运用绝对定量实时聚合酶链锁反应（Q-PCR）技术探究其微生物学强化机制.结果表明:长期连续运行成功塑造了高效的木质纤维素瘤胃强化体系.该体系的最高有机负荷达8.90 g/（L·d）（以VS计）,是强化前的1.53倍,该有机负荷下半纤维素和纤维素降解率分别达73.9%和40.1%,单位质量底物沼气和甲烷产量相应地分别达到451和261 mL/g（以VS计）,半纤维素和纤维素较高的降解率是该体系维持高产气性能的主要原因.生物相机制研究表明,瘤胃微生物强化体系中与木质纤维素水解密切相关的GH5（糖苷水解酶家族5）水解菌逐步富集,其基因拷贝数从初始的964×1010 copies/g升至最高有机负荷下的6.83×1011 copies/g,这是底物在高有机负荷下仍能被高效生物转化的根本原因.研究显示,瘤胃微生物的介入可有效强化体系底物的降解能力,促进醋糟产甲烷性能的提升.      

弱势人群社区居家安全现状分析及预防策略

为减少弱势人群居家安全伤害事故,采用分析法对某街道社区的医疗伤害监测系统数据进行分析,结合对儿童的问卷调查。结果显示,这个街道老年人、残疾人发生伤害事故比例最高的是跌倒,分析发生伤害的原因,除其身体因素外,缺乏居家安全防护设施及相适应的辅助工具是主要原因;儿童伤害主要是由于缺乏安全知识和好奇心导致。通过有针对性的对老人、儿童、残疾人的安全知识宣传和居家安全设施的改善可以降低伤害事故率。     

生态社区建设中环保教育的代际引导机制调查研究

居民既是社区生态环境改善的受益者,也是推动和监督社区环境治理的根本动力.充分利用文献法、入户访谈、问卷调查法及案例分析法,调查生态社区环境治理背景下家庭环保教育的代际引导机制,发现:学生对于室外实践课和手工实践课兴趣很高,比较排斥室内文本形式的环保教育.超过82.4%的家长期望孩子在环保课堂中可以学习到环保知识,超过61%的家长愿意配合学生完成环保课外实践.目的:研究确实有效的家庭环保意识传递方式,为社区、学校的环境教育提供高效的教学方案.     

Juggling work and family responsibilities when involuntarily working more from home: A multiwave study of financial sales professionals

Using multiwave survey data collected among 251 financial sales professionals, we tested whether involuntarily working more from home (teleworking) was related to higher time‐based and strain‐based work‐to‐family conflict (WFC). Employees' boundary management strategy (integration vs. segmentation) and work–family balance self‐efficacy were considered as moderators of these relationships. Data were collected one month before, three months after, and 12 months after the implementation of a new cost‐saving policy that eliminated employees' access to office space in a centralized work location. The policy resulted in employees being forced to work more from home. A voluntary telework program had been in effect before the new policy, implying that working more from home as a result of the new policy was involuntary in nature. Results revealed that involuntarily working more from home was associated with higher strain‐based WFC but not higher time‐based WFC. However, moderator analyses revealed that the positive association between involuntarily working more from home and both types of WFC was significantly stronger among employees with weaker self‐efficacy in balancing work and family. Boundary management strategy had no detectable moderating effect. Copyright © 2015 John Wiley & Sons, Ltd.     

Got milk? Workplace factors related to breastfeeding among working mothers

The American Academy of Pediatrics recommends that women breastfeed because of improved health outcomes for mothers and children. Because maternal employment during the first year of the child's life has been identified as a reason for breastfeeding cessation, we develop and test a role‐theory‐based framework to explain women's continuation of breastfeeding after return to work (Study 1) and report results of an exploratory study linking breastfeeding at work with job attitudes and well‐being (Study 2). Applying survival analysis to a longitudinal dataset gathered by the Centers for Disease Control (Study 1), we identify pregnant women's perceived employer support for breastfeeding as a predictor of women's breastfeeding goal intentions. Supervisors' negative workplace remarks about breastfeeding related to an eightfold increase of women's likelihood to discontinue exclusive breastfeeding and perceived support for breastfeeding after return to work predicted exclusive breastfeeding continuation. Results of Study 2 suggest that women who return to work and continue breastfeeding experience more family‐to‐work conflict and overload than women who do not reconcile work and breastfeeding. Further, results of Study 2 provide preliminary evidence suggesting that perceptions of supervisor and coworker support for breastfeeding relate positively to general perceptions of organizational support and negatively to depressive symptoms.
