Creating team ambidexterity: The effects of leader dialectical thinking and collective team identification

In the current, increasingly dynamic environment, more attention is being devoted to ambidexterity (both explorative and exploitative learning), as it is beneficial to organizational functioning. Despite an abundance of research on organizational ambidexterity, there is a paucity of research examining team-level ambidexterity. In a cross-level empirical study, we examine a leader's dialectical thinking as an antecedent of team-level ambidexterity. We also incorporate collective team identification as a moderator in the study. Our findings support that a leader's dialectical thinking can help facilitate team ambidexterity that, in turn, improves employee performance. Those teams whose members have strong team identification and whose leader is high in dialectical thinking will reap the most benefit from team ambidexterity.     

故事剧表演活动中绘本改编策略——以绘本故事剧《今天运气怎么这么好》为例

绘本故事剧是幼儿园常见的戏剧活动之一。在开展绘本故事剧活动时常常需要对绘本进行适当的改编，以使绘本故事剧的情节更丰富、台词更生动、内容更具亮点。可以运用多种策略对绘本故事进行改编，如通过迁移生活经验,让故事剧内容的改编更具生活性；遵循表达特点,让故事剧台词的改编更具生动性；顺应发展逻辑.让故事剧的情节改编更具丰富性等，让绘本故事剧在幼儿的二次创作中无限伸展、无限改变，爆发出无限创意。     

Role ambiguity and volunteer board member performance in nonprofit sport organizations

We explore the relationship between multidimensional role ambiguity and individual board member performance within nonprofit voluntary sport organizations. Role ambiguity accounted for 29 percent of the variance in perceived board member performance, and ambiguity about one's responsibilities was the strongest predictor. These findings extend our understanding of the drivers of individual board member performance within voluntary sport organizations and the multidimensional nature of role ambiguity. The study supports previous arguments that knowing what to do is fundamental to one's performance, and more critical than knowing how to do it, and what difference it makes.     

政府绩效管理存在的误区及对策

随着社会的发展，公众对政府管理和服务的质量、效率和公正性等要求不断提高，绩效管理已经成为政府应对全球化和国际竞争环境的普遍改革措施。政府绩效管理作为一项有效工具在西方发达国家的运用已相当成熟，很多成功经验和理论近年来也在我国得到大力推行。转变机关作风，实施目标绩效管理，已成为提升各级政府的服务质量和城市竞争力的重要元素。要通过绩效管理有效地推动政府健康快速转型，首先应当厘清政府在绩效管理中存在的误区，才能为完善绩效管理提供有效对策。     

Does task-related conflict mediate the board gender diversity–organizational performance relationship?

The board gender diversity–organizational performance relationship has been criticized for the absence of tests of the underlying mechanisms of this relationship. This study aims to empirically investigate whether task-related conflict – one of the prime theorized mechanisms of board diversity – indeed mediates this relationship. Consistent with the literature, we theorize how board gender diversity affects task-related conflict, and how task-related conflict in turn affects organizational performance. We test our hypotheses in the Dutch water authority sector 2009–2014, where we have access to the detailed board meeting minutes of 27 organizations. Our results find support for a partial mediating effect of task-related conflict in the board gender diversity–organizational performance relationship. We conclude by discussing the implications for the board gender diversity literature.     

Effect of regulatory modes on work performance: the moderating role of job familiarity and job complexity / El efecto del modo de regulación en el rendimiento laboral: el rol moderador de la familiaridad con el trabajo y la complejidad de la tarea

Prior research has shown that the combination of assessment and locomotion regulatory modes leads to the best performance-related outcomes. The aim of the current study was to analyse how familiarity and complexity moderate this relationship between the two regulatory modes and job performance. Participants’ locomotion and assessment tendencies were measured, and they were asked to rate the familiarity and complexity of their daily work tasks, as well as their job performance over the last year. Results showed that when job tasks were unfamiliar and more complex, high locomotion and high assessment were both needed for optimal performance. However, when both familiarity and job complexity were low, high locomotion alone led to the best performance. A similar result was obtained when task familiarity was high: regardless of task complexity, the best performance was shown by employees high in locomotion, no matter the assessment. In conclusion, the present study furnishes useful suggestions for employers who wish to maximize employees’ performance.     

After the March: Using Instagram to Perform and Sustain the Women's March

The January 2017 Women's March was an example of the paradigmatic March on Washington, part of the repertoire of collective action used by social movements in the United States for decades. Similar marches were held on its first and second anniversary, in January 2018 and January 2019, respectively. One did not need to travel to the nation's capital to participate in these marches, however; activists also organized hundreds of “sister marches” across the United States and internationally. Yet, a sole focus on these one‐day, physical events misses a great deal of activity. In this article, we examine social media activity related to the Women's March on the platform Instagram that was posted well after the 2017 march was over but before the 2018 march was fully planned. We do so to gain purchase on how individuals and organizations use social media to maintain movements between large events. We analyze a systematic sample of Instagram posts from two sources: (1) individual Instagram users’ public posts with the hashtag #womensmarch and (2) posts from the official Instagram account of the Women's March. Conceptualizing these posts as political performances, we use our findings to draw implications for the study of contemporary protest.

硫沉积气藏产量递减模型研究

以往对高含硫气藏开发技术研究所需录取的资料在实际操作过程中难以得到。因此，针对井筒附近发生硫沉积的高含硫气藏，建立了硫沉积复合气藏产量递减数学模型，运用 Stefest 数值反演绘制了 Blasingame 产量递减曲线，并分析了硫沉积对气井产量递减规律的影响。结果表明：产量递减中期，硫沉积区含硫饱和度越高，无因次递减产量积分“导数”曲线下凹越深，当含硫饱和度增大到 0.5 时，积分“导数”曲线下凹至最深，积分“导数”达最小值；硫沉积半径越小，无因次递减产量平缓段出现的时间越早；产量递减后期，无因次递减产量积分与积分“导数”曲线晚期为一条斜率为–1 的直线，表现为调和递减。该方法比压力恢复试井法更具优越性，可为高含硫气藏的开发提供指导。     

桥梁横向地震碰撞响应研究进展

在强震作用下，桥梁上、下部结构由于动力特性的不同而发生不同相振动，从而引起梁体与挡块间的非线性碰撞。汶川大地震中，大量公路桥梁遭到严重破坏，横向抗震挡块破坏尤其严重，其中部分是由于横向碰撞而引起。针对这种碰撞现象，对正交简支梁桥、连续梁桥、斜交桥及高速铁路桥梁的横向碰撞反应进行了回顾和总结，并介绍了横桥向防撞措施及震后加固技术的研究现状，同时指出目前我国在这方面亟需解决的问题和进一步研究的方向。
