Testing two mechanisms linking work-to-family conflict to individual consequences: do gender and gender role orientation make a difference?

Based on social role theory and a gender role orientation perspective, this study extended the two mechanisms (i.e. resource depletion and source attribution) that link work-to-family conflict to perceived accomplishment in the family and work domains by testing the moderating effects of gender and gender role orientation on the relationships. Data were collected from managers via questionnaires in China, and 225 cases were analyzed with hierarchical regression models. The results showed that compared with female managers, the negative relationship between work-to-family conflict and perceived family accomplishment was stronger for male managers. Within the male group, we found that the negative relationship between work-to-family conflict and perceived family accomplishment was stronger for male managers with an egalitarian gender role orientation than those with a traditional gender role orientation. In addition, for male managers with a traditional gender role orientation, there was a positive relationship between work-to-family conflict and perceived work accomplishment. The theoretical and managerial implications are discussed.     

Inventor Chief Executive Officers and Firm Innovation

Using a novel, manually collected dataset, we find that firms whose chief executive officer (CEO) is an inventor experience significantly better innovation outcomes, as measured by patents and future citations. We obtain these results in models with firm fixed effects, in difference‐in‐difference analysis of transitioning CEOs that controls for the CEO fixed effects, and among firms with founder CEOs. Firms led by an inventor CEO also exhibit greater tolerance for failure as indicated by a greater number of both highly cited and uncited patents, and engage more in explorative search strategies that exploit new technological trajectories. Stock market, however, seems unable to fully capture the positive impact of inventor CEOs on future innovation: firms whose CEO transitions to be an inventor experience positive abnormal stock returns, especially during the early years following the transition.     

内科重症监护病房耐药鲍曼不动杆菌流行病学分析

目的探讨内科重症监护病房(MICU)耐药鲍曼不动杆菌流行病学。方法收集2011年1月至2013年12月MICU送检的菌株标本637株,进行菌株分离鉴定及药敏试验,再行细菌菌谱及耐药性分析。结果 3年来分离出的鲍曼不动杆菌株占所有分离菌株总数的40.0%。除了替加环素,鲍曼不动杆菌几乎对所有抗生素的耐药率在70.0%以上,且有逐年增加的趋势;对碳青霉烯类耐药率达95.0%以上。结论 MICU鲍曼不动杆菌是主要流行病菌,其耐药率极高,除了鲍曼不动杆菌本身的属性外,还与交叉感染、消毒隔离及抗生素的应用有关。     

从网络广告监管到网络广告治理——公共治理的视角分析

目前,我国网络广告正在逐步勃兴,与此同时,传统的广告监督管理体制与网络广告发展不相适应的问题也日益突出,引发了许多矛盾和冲突。面对市场和政府的双失灵,实现由传统的网络广告监管向网络广告治理的转变成为必然选择。网络广告治理是一项系统工程,单纯依靠政府职能部门无法实现预期效果,需要政府、社会组织、民众等多方共同参与,强调服务导向和参与意识,明确各自的责任,从而形成良好的合作网络,实现网络广告的有效治理。     

我国A股市场定向增发定价的实证研究

本文以2006—2008年6月实施定向增发的200家上市公司为样本,利用多元线性回归模型对定向增发定价的影响因素进行了实证分析。结果表明,如果发行公司的控股股东、实际控制人或其控制的关联人参与定向增发,则定向增发的发行折价率较大,其认购比例越大,折价率越大;在发行过程中,发行对象关注的是上市公司的发展能力和拟投资项目的风险,发行前公司的财务状况对定价的影响不显著;公司的股本规模有着稳定发行价格的作用。     

渔民收入增加对渔业产业结构调整的影响

论文首先利用1990-2015年中国渔业统计年鉴数据实证回归得出,渔民收入增加借助资本投入和技术进步对渔业产业结构调整的影响显著,而劳动力投入的作用不显著。然后进一步测定了各投入要素对渔业产业结构调整的贡献率,得出渔民收入增加引致的渔业资本和技术投入对产业结构调整的贡献较大,而劳动力的贡献较小且不断下降。最后基于实证结果针对渔业产业结构调整提出应提高渔民收入水平、加大补贴力度、实现渔业产业化经营等建议。     

Stable Discovery of Interpretable Subgroups via Calibration in Causal Studies

Building on Yu and Kumbier's predictability, computability and stability (PCS) framework and for randomised experiments, we introduce a novel methodology for Stable Discovery of Interpretable Subgroups via Calibration (StaDISC), with large heterogeneous treatment effects. StaDISC was developed during our re-analysis of the 1999–2000 VIGOR study, an 8076-patient randomised controlled trial that compared the risk of adverse events from a then newly approved drug, rofecoxib (Vioxx), with that from an older drug naproxen. Vioxx was found to, on average and in comparison with naproxen, reduce the risk of gastrointestinal events but increase the risk of thrombotic cardiovascular events. Applying StaDISC, we fit 18 popular conditional average treatment effect (CATE) estimators for both outcomes and use calibration to demonstrate their poor global performance. However, they are locally well-calibrated and stable, enabling the identification of patient groups with larger than (estimated) average treatment effects. In fact, StaDISC discovers three clinically interpretable subgroups each for the gastrointestinal outcome (totalling 29.4% of the study size) and the thrombotic cardiovascular outcome (totalling 11.0%). Complementary analyses of the found subgroups using the 2001–2004 APPROVe study, a separate independently conducted randomised controlled trial with 2587 patients, provide further supporting evidence for the promise of StaDISC.     

Investor sentiment and advertising expenditure

A strategic issue facing marketing managers is ‘how much and when’ to spend on advertising. We argue that investor sentiment in the stock market may influence advertising expenditure by affecting firms' ability to raise new funds. We show that during periods of low (high) investor sentiment, firms decrease (increase) their advertising expenditure, even though the effectiveness of advertising is greater (lower) during such periods. We also find that these results are stronger for financially constrained firms that rely more on external financing. Our findings suggest that marketing managers can improve the efficiency of their advertising expenditure by raising (reducing) it during periods of low (high) sentiment.     

汽车供应链安全对钢铁企业的影响

疫情对企业造成的短期影响体现在企业当下面临的经营压力,中长期影响则较多地反映在供应链及市场需求方面。汽车产业是供应链全球化程度及细分度高的行业,疫情引起的问题更加突出。汽车产业对产业链上游行业的拉动力强大,作为钢铁行业下游需求端的代表行业,是2019年我国钢铁行业第三大需求端,钢材消费量5 000万吨。基于此,分析汽车产业链对钢铁企业的逆向影响。
