山东省城市创新空间关联网络演变特征及影响因素分析

基于2014～2017年山东省17个地级市创新联系能力,借助修正引力模型构建城市创新联系能力空间关联的有向加权矩阵,运用社会网络分析法及QAP回归方法探讨城市创新联系能力空间网络结构特征及空间传导关系的形成机制。结果表明：①山东省城市创新联系能力空间关联网络的网络密度加大,网络整体连通性增加,内陆中部、东部沿海地区城市处于网络的中心位置,易与其他城市发生空间关联,起到城市之间产生空间关联的“桥梁”作用。②内陆地区的“多三角型”与沿海地区的“倒T型”强关联网络得以扩展,边缘城市依赖于核心城市发展,形成具有较强关联的稳健性复杂创新网络。③地理距离、人力资本水平差异、政策支持力度差异、企业信息化水平差异对山东省创新联系能力空间关联网络结构的影响方向及回归结果较为稳健。     

Enacting Cultural Identities in Conversation: Managing Collaboration in Two Nonprofit Organizations

As they conduct the practical work of collaborating during meetings, nonprofit stakeholders construct, negotiate, and manage identities. In this article we use membership categorization analysis to explore how meeting participants avow and ascribe cultural identities during collaborative meetings in two nonprofit organizations. Examination of identification practices, including employing labels for ethnic categories and implicating cultural identities through category-relevant predicates—which are part of the practical work of collaborating in nonprofit organizations—can serve as an aid to understanding how stakeholders negotiate interorganizational collaboration in social interaction.     

National Football League head coach race,performance, retention,and dismissal

The authors tested for evidence of racial discrimination in the employment retention of National Football League head coaches. A robust data set spanning the modern history of the sport (1985–2018) was generated to examine managerial employment tenure, dismissal, and subsequent organizational performance. After controlling for performance differences and heterogeneity between head coaches, the authors uncover statistically significant evidence that Non-White head coaches experience longer employment spells relative to White head coaches in the Rooney Rule era. No statistically significant evidence of racial differences in the rate at which head coaches are fired is found. Both employment tenure and dismissal are largely driven by raw performance, and to a lesser degree, relative performance. Finally, the relationship between head coach race and organizational performance is examined, but no statistically significant differences by race are uncovered.     

形成性评估应用于大学英语听力教学的绩效研究

实验研究得知,相较于终结性评估,形成性评估应用于大学英语听力教学不仅能够更为有效地激发和提高学生的学习动力,而且更能有效地提升听力学习绩效;形成性评估更能激发学生的听力学习自主性和合作性,提高其听力自主学习能力和合作学习能力.形成性评估能促使教师转变教学方式,改进听力教学,对提高教学质量和教学绩效有一定的意义.     

基于CIPP模式的高校辅导员考核评价体系

高校辅导员在实际工作中的角色多重性必然在很大程度上导致高校对这些辅导员考核评价的现实困扰。一些传统的辅导员考核评价模式存在着评价方式运用的趋同性、评价指标运用的主观性和评价结果运用的终结性等实际问题。基于背景、输入、过程和成果四位一体的CIPP综合评价模式,呈现出评价维度的多元性、评价方式的多样性和结果运用的持续性等优点。基于此模式,可以从优化辅导员绩效评价的指标结构、改进辅导员绩效评价的考核方法、关注辅导员考核评价的外部影响等方面建构高校辅导员考核评价体系。     

Evening electronic device use and sleep patterns in athletes

The present study aimed to investigate pre-sleep behaviours (including evening electronic device use) and sleep quantity in well-trained athletes. Seventy well-trained athletes (44 females, 26 males) aged 21 ± 4 y from a range of team and individual sports were asked to complete an online sleep diary for 7 days. The sleep diary included questions about pre-sleep behaviours (e.g. napping, caffeine intake), electronic device use in the 2 h prior to bedtime (e.g. type of device and duration of use) and sleep (e.g. time in bed, sleep onset latency). On average, athletes spent 8:20 ± 1:21 h in bed each night. Associations between age, time in bed and sleepiness suggested that younger athletes spent more time in bed (B = -0.05, p = 0.001) but felt sleepier (r = -0.32, p < 0.01) than older athletes. On average, athletes mostly used electronic devices for 0–30 min prior to sleep. The use of multiple devices in the evening was associated with more perceived difficulty in falling asleep (B = 0.22, p = 0.03), but no associations existed with other sleep variables. In summary, younger athletes may require later start times or improved sleep quality to resolve excessive sleepiness.     

Does performance justify the underrepresentation of women coaches? Evidence from professional women’s soccer

In this paper, the authors empirically analyze the influence of the gender of the coach on team performance in women’s soccer leagues. Moreover, the authors examine the role of initial experience of coaches (as professional players) as an attribute that converges with gender diversity and influence performance. The sample includes the top divisions in France, Germany, and Norway from 2004 to 2017. The results from the regression model show that the gender of the coach is not a significant determinant of team performance (points per game). In addition, the initial experience of coaches does not alter the results. Therefore, managerial decisions of clubs with regard to the employment of coaches should not rely on gender.

近红外光谱分析技术在肥料成分分析中的应用及前景

近红外光谱是一种快速、无损、可实现多组分同时测定的分析技术。本文简要介绍了近红外光谱的发展、测量原理、技术特点．并对近年来近红外光谱技术在肥料成分分析中的应用及前景进行了总结。近红外光谱在肥料成分分析中的应用范围比较狭窄,主要集中在两个方面：一是利用近红外反射光谱（NIRS）分析技术快速测定各种畜禽粪便主要肥料成分含量;二是应用近红外光谱技术在土壤及土壤肥料学科中的应用;只有极少量的关于混合（复合）肥料的研究。随着近红外光谱技术的不断成熟,除了应用范围将不断拓宽之外,相信对于目前较为空白的应用机理的研究也将越来越深入、细致及严谨。
