提升中小学生阅读兴趣的实证研究——基于MIMIC模型的教学效能分析

提升学生的阅读素养是当前我国阅读课程教学改革的重要目标之一。本研究首次尝试将群文阅读这种新兴的阅读教学方式与传统的单本阅读教学方式进行对比研究，主要从提升学生阅读兴趣的效能方面进行分析与探讨。实验涉及我国中西部5个省市、6个区县共计1 231名中小学生，并使用MIMIC模型，在有效控制测量误差的基础上，对实证数据进行了量化建模与分析，通过分析发现，群文阅读教学对激发学生阅读的“情境兴趣”有更加显著的作用，具体表现为对学生阅读注意力、情感体验、探索意愿、价值感知的影响更大，同时也验证了Knogler提出的“情境兴趣模型”在阅读教学领域的适用性，从而为进一步推进我国中小学阅读课程教学改革提供了科学的数据支撑。因此，为提升中小学生阅读素养，在阅读教学中引入群文阅读这一新兴的教学方式，具有重要的实践价值和现实意义。     

A visual planning solution to streamline the processes of hybrid cross-dockings

Cross-docking is a logistic strategy widely adopted both in manufacturing and distribution contexts. Despite the huge number of researches on this topic, most of them remain rather theoretical as they do not pay enough attention to operational aspects and daily functioning patterns of cross-dockings. This article aims at introducing a new focus for cross-docking research by proposing a visual planning solution to manage daily operation of a manufacturing cross-docking. By avoiding complex optimization algorithms and by adopting concepts belonging to the lean management theory, the article shows the potential of visual planning techniques to improve performance of cross-dockings. Starting from a specific industrial context, the shipping warehouse of an Italian company of the oil andand gas sector, a visual management methodology has been proposed to support the operation of cross-dockings. Although developed in a particular context, the proposed methodology and its underlying principles are to be considered general and potentially applicable to a wide range of cross-dockings. The methodology fully exploits an analytical tool, namely, the Safety Margin coefficientthat could be used for capacity planning purposes and to evaluate quantitatively the system performance at a given time instant.     

Beliefs underlying stress reduction and depression help-seeking among college students: An elicitation study

Objective: This study illustrates how a theory-based approach can identify college students’ beliefs about stress reduction activities and help-seeking for depression. These beliefs are the basis for intervention design. Participants: A sample of 53 undergraduate students at a public university in the Midwest participated in this research during March 2016. Methods: An open-ended belief elicitation survey was administered online. Beliefs were identified through qualitative thematic analyses. Results: Exercise was students’ most preferred stress reduction activity. Beliefs about exercise emphasized physical benefits yet also not having time for exercise. Beliefs about help-seeking for depression emphasized treatment efficacy, support from others, stigma, and time constraints. Conclusions: Whereas beliefs about positive outcomes inform educational and motivational messages, beliefs about time constraints underscore the need to also consider structural factors that can help students find time to attend to their well-being.     

Teaching technologies for immigrant children: an exploratory study of elementary school teachers in Russia*

ABSTRACT

Educational institutions are an important setting where psychological, pedagogical, sociocultural, and language adaptation of immigrant children occurs. A number of teaching strategies, practices, approaches, and methods have been described in the literature. In the Russian context, such strategies have been called ‘technologies’. The purpose of the present exploratory study was to describe teaching technologies used by teachers in Russia when working with immigrant students in elementary schools. Responses of forty-five elementary school teachers to open-ended questions describing technologies they use when teaching children with migration backgrounds were analyzed using content analysis. Findings suggest that Russian elementary school teachers used ethno-cultural group, communicative technologies, games, individualized instruction, and differentiated teaching. Many approaches mentioned can be used inclusively with groups of immigrant and non-immigrant students. Importantly, while teachers supplemented classroom instruction with additional Russian language lessons, none mentioned specific techniques for teaching Russian as a non-native language. These findings are discussed in relation to teaching strategies described in the international literature focused on migrant students. Finally, implications for further research are discussed.     

股权质押与市值管理:基于中国沪深股市A股上市公司的实证检验

本文以沪深两市上市公司为研究对象，基于2012-2016年的样本数据，运用STATA14探讨了上市公司发生股权质押后，相较不存在股权质押的公司是否会更有可能进行市值管理，以及股权质押、股权激励和市值管理三者之间的传导机制。基于相关数据的实证结果显示，控股股东在发生股权质押行为后，为了避免股价发生异常波动或者持续下跌从而引发公司治理层面的风险，相较不存在控股股东股权质押情形的公司的确更有可能进行市值管理；进一步分析发现，股权质押后，控股股东会通过股权激励这种手段来进行市值管理。     

基于信息披露文本的上市公司财务困境预测:以中文年报管理层讨论与分析为样本的研究

本文采用文本分析方法研究了中文年报管理层讨论与分析传递的管理层语调能否提供财务困境预测的增量信息、能否提高预测的准确性以及文本内容的信息价值，主要结论为：（1）管理层语调确实为财务困境预测提供了新的信息，能提高财务困境模型的拟合程度和预测能力；（2）管理层语调是对定量财务数据的重要补充，而且这些信息并没有在市场交易价格中得到充分反映；（3）负面语调比净语调具有更高的信息价值；（4）财经文本情感或语调的分析应以基于相关来源财经文本的情感词词典为基础，而直接引入其他领域成熟词典的效果较差。     

地方高校推行教师学术休假制度的现实意义与实施策略

教师学术休假是促进教师专业发展的重要形式，是教师自我完善的需要，是提升教师理论水平、科研能力和教学技能的主要手段，是提高教学质量的有效途径。探讨地方高校推行学术休假制的必要性，提出地方高校推行学术休假的建议，对地方高校教师队伍建设具有重要的现实意义。在实施策略上，应注重4个方面：（1）明确参加学术休假的对象主要是教师和教学科研人员；（2）根据教师职业发展的阶段性确定学术休假的时间；（3）合理设置学术休假人员遴选条件，首先应考虑为工作满5年以上的青年教师提供学术休假，其次应考虑为高级职称教师提供学术休假；（4）明确学术休假期间的教师待遇，并加强对学术休假人员的管理。     

城市治理的基本假设及其幻想

当前关于城市“管理”的理论研究中，“城市治理”的话语正在取代“城市管理”，由此形成的各种对城市的认知也反映在城市的实践中，譬如，提倡提高公众参与、实施精细化治理、信仰信息技术等。通过审视城市治理主张的公众参与假设、技术治理假设和空间治理假设，文章提出治理理论的兴起不足以取代城市管理理论;对管理主义的批评，不能通盘否定“管理”理论对城市的重要作用。主张重塑城市管理理念，以管理思想处理理性与自由的关系，理清并守住政府的职责，警惕唯市场效率，探索多元价值的平衡之道，贡献管理公共性的经验，促进国家治理能力和治理体系的现代化。     

Impression management in corporate annual reports during the global financial crisis

This paper analyses impression management (IM) during the global financial crisis (GFC). It examines the differences in multiple textual characteristics and attributions between a highly positive performance period (2002–2007) and the GFC period (2008–2012), within the setting of Spain, where these two economic cycles were extreme. In contrast to previous research, companies' extreme poor performance in our sample is driven by an exogenous event. The findings do not show clear evidence of IM based on textual characteristics specifically linked to the GFC. Companies tried not to use overt IM and, to some extent, tried to clarify the impact of the crisis on performance. They were under great scrutiny and probably preferred to tell a more careful story. However, a general pattern of IM was still present during the GFC in the form of consistent positive attributions, favourable benchmarks and enhancement practices. In essence, the crisis did not fully stop IM practices, but rather influenced the way IM was produced. Overall, our results show that IM was lower during the GFC than in the case of poor performance in normal macroeconomic conditions found by previous literature. The results also show that the narratives of firms in the finance and real estate sectors were the most reactive to the GFC, probably linked to their key role in the crisis.
