城市土地收购储备制度运行的经济学分析

城市土地收购储备制度是近几年出现的一种政府干预与土地市场相结合配置土地资源的创新机制。城市土地收购储备制度的运行对城市土地资源配置效率产生了积极的影响。文章从经济学角度对城市土地收购储备运行状况进行分析,进而提出了加强政府宏观调控、完善城市土地收购储备制度的建议。     

幼师职业倦怠的现状、成因及对策研究——以河北省秦皇岛市为例

选取秦皇岛市部分有代表性的幼儿园进行调查,通过对调查数据的统计分析,发现幼儿教师的职业倦怠现象普遍存在。其产生主要原因与幼儿教师自身因素、社会因素、幼儿园管理因素等相关。并从社会、幼儿园及幼儿教师的角度提出缓解幼儿教师职业倦怠的策略。     

国家治理现代化的共识凝聚及其实践方向

在新时代全面深化改革的背景下,共识凝聚既是中国共产党汇聚改革动力、形成改革合力的基本前提,也是改革目标达成和有效落地的重要依托。这既是全面深化改革统筹推进的系统化要求,也是国家治理现代化具体目标的协同性表现。中国共产党在全面深化改革的伟大斗争中必须广泛凝聚共识,有效调动一切治理能力,进而逐步达到国家治理体系和治理能力现代化的总目标。协商民主是实现党的领导的重要方式,中国特色的协商民主以平等、理性、面对面交流的优势适应了多元主体、多元利益和多元价值之间的综合协调特点,体现人民当家作主的本质要求,为国家治理现代化进程的共识凝聚提供了一个有益的可行的实践思路。     

尚未完成的"现代"--也谈中国现当代文学的分期

中国现代文学的上限应该定在晚清,而非"五四新文化运动".中国文学的现代性追求并未止于1949.1949只是政治划界,此后中国文学发生了许多激变,呈现出复杂的现代性样式.晚清至今的中国文学仍然属于尚未完成的现代.通常所谓从"五四"到1949年"现代文学"应该作为特殊的学术史概念来使用,而1949年至今的"当代文学"则应该理解为一个文学批评而非文学史的概念.以往所谓的"现当代文学"只是一个暂时性的提法,似乎应该为重新作出解释的现代文学所取代.     

基于土地发展权分配的征地区片综合地价研究

征地区片综合地价的实施在一定程度上为农村集体利益提供了政策保障,但由于现行征地区片综合地价的测算本质上仍然基于被征土地的农业用途,还达不到保障农民生活水平的目的,尚不能从根本上解决失地农民问题.失地农民不能分享农用地用途转换所获得的土地发展权收益是问题的关键.借鉴实践中划拨土地使用权转让收益的分配方式,国家和农村集体按60%和40%的比例分享土地发展权收益,并利用部分资金共同出资建设失地农民社会保障体系是可行之策.改进征地区片综合地价测算方法,使土地发展权的分配在现实中得以实现.从建设用地出让金中扣除农地经营性收益和广义土地开发成本,得到土地发展权收益;通过对农民意愿的调查,确定农村集体分享的土地发展权收益比例,进而得到分享的土地发展权收益,其与农地经营性收益之和就是征地区片综合地价.     

学区在教育变革中的作用

美国和加拿大对于学区在教育变革中的作用研究已有近40年的历史.关于学区在教育变革中的作用研究可划分为几个具有不同特点的时期,包括创新实施时期、高效学校范式时期、学校重构时期和基于标准的变革时期.综述列举了不同研究时期最重要的一些研究,并讨论了它们的研究特点和成果.在关于成功学区的案例研究的基础上,着重分析了学区在系统改进学生学习的过程中所面临的挑战、学区改进学生学习所采取的策略以及学区影响教学和学习质量的证据.同时,总结并讨论了12条促进学生学习的学区策略,提供了5个关于学区在教育变革中的作用的研究方向.     

Leader individual differences,situational parameters,and leadership outcomes: A comprehensive review and integration

In this article, we provide a wide-ranging review of recent research on leader individual differences. The review focuses specifically on the explosion of such research in the last decade. The first purpose of this review is to summarize and integrate various conceptual frameworks describing how leader attributes influence leader emergence and leader effectiveness. The second purpose is to provide a comprehensive review of empirical research on this relationship. Also, most prior reviews primarily examined leader personality traits; this review includes a broader array of leader attributes, including cognitive capacities, personality, motives and values, social skills, and knowledge and expertise. The final broad purpose of this paper is to review and integrate situational and contextual parameters into our conceptual framing of leader individual differences. Few, if any, prior reviews have systematically accounted for the critical role of such parameters in cuing, activating, or delimiting the effects of particular leader attributes. We do so in this article.     

Almost Like a Real Band: Navigating a Gendered Jazz Art World

Professional jazz has been organized around two contradictory cultures. Historically, the jazz art world has followed norms of meritocracy, which promote equality across boundaries of race and class. At the same time a culture of exclusivity, anchored in gendered essentialism, has severely limited female participation. By analyzing interview data with artists from the Hamilton College Jazz Archive, we illustrate how these contradictory cultures of inclusion and exclusion operate to channel women into feminized roles in the jazz world. We then discuss how women employ a number of strategies to work around the culture of exclusivity and capitalize on the norms and values of musical meritocracy. Despite institutional openings in professional jazz that emerged following the women’s movement, female jazz artists continue to face strong barriers toward full equality in the jazz world. Although female artists consistently demonstrate that they possess equal musical skills to male musicians according to the norms of meritocracy that guide professional jazz, women remain on the margins of the jazz art world.     

Integrated methodology for multiple systems estimation and record linkage using a missing data formulation

There are now three essentially separate literatures on the topics of multiple systems estimation, record linkage, and missing data. But in practice the three are intimately intertwined. For example, record linkage involving multiple data sources for human populations is often carried out with the expressed goal of developing a merged database for multiple system estimation (MSE). Similarly, one way to view both the record linkage and MSE problems is as ones involving the estimation of missing data. This presentation highlights the technical nature of these interrelationships and provides a preliminary effort at their integration.     

Consultants' forum: should post hoc sample size calculations be done?

Pre‐study sample size calculations for clinical trial research protocols are now mandatory. When an investigator is designing a study to compare the outcomes of an intervention, an essential step is the calculation of sample sizes that will allow a reasonable chance (power) of detecting a pre‐determined difference (effect size) in the outcome variable, at a given level of statistical significance. Frequently studies will recruit fewer patients than the initial pre‐study sample size calculation suggested. Investigators are faced with the fact that their study may be inadequately powered to detect the pre‐specified treatment effect and the statistical analysis of the collected outcome data may or may not report a statistically significant result. If the data produces a “non‐statistically significant result” then investigators are frequently tempted to ask the question “Given the actual final study size, what is the power of the study, now, to detect a treatment effect or difference?” The aim of this article is to debate whether or not it is desirable to answer this question and to undertake a power calculation, after the data have been collected and analysed.
