《湖南农民运动考察报告》在毛泽东的众多著作中占据极其显著的地位,它不仅包含着丰富的具体理论和内容,也蕴含着深邃的方法论思想。从思想政治教育视角剖析《湖南农民运动考察报告》可以发现其蕴含着丰富的方法论思想,例如调查研究方法、注重群众力量工作方法、具体问题具体分析方法、问题意识以及创新思维的工作方法等等。认真学习和领会这些方法对于今后一个时期做好思想政治教育工作具有重要的方法论借鉴意义。  相似文献

中国专利产出绩效的空间计量经济分析   总被引:1,自引:0,他引:1       下载免费PDF全文
本文在规模报酬可变情况下,采用全要素生产率分析框架,从生产理论的角度,综合考虑了纯技术效率变化、规模效率变化、技术进步和技术效率变化,并利用知识生产函数构造了可考察动态变化的DEA-Malmquist专利产出绩效指数。然后运用2000-2008年我国30个省区的社会经济面板数据对专利产出绩效进行实证分析,并采用空间计量经济方法对其区域差异性和影响因素进行综合考察。研究结果显示,中国省域专利产出绩效在总体上呈上升趋势,其分布态势表现出了明显的空间自相关性,且其中"创新者"主要集中在中国东部沿海地区。在全国范围内,区域经济发展水平、产业结构、城市化水平对于专利产出绩效存在明显的推动作用;而在短期内,技术市场成交额和受大专以上教育(十万人)的人力资源产出指标对于绩效水平的提升缺乏显著贡献。  相似文献

本文从理论和实证角度,分析验证了城市轨道交通对沿线站点住房价格的影响。首先通过理论分析提出假说,然后基于特征价格方法构建计量分析模型,利用南京市地铁1、2号线站点附近2km范围内二手楼盘数据,实证分析了城市轨道交通地铁对沿线站点住房价格的影响。结果表明:1城市轨道交通对沿线站点住房价格产生了显著的增值效应,不同距离范围影响程度不同,距地铁站点500m以内住房价格比500m以外高出14.3%,1 000m以内住房价格比1 000m以外高出8.9%,1 500m以内住房价格比1 500m以外高出3.9%,当距离范围超过1 500m后,增值效应在统计上不显著;2轨道交通对住房价格的影响程度与距地铁站点直线距离存在着显著的倒"U"形关系,影响程度随距离先增大后减小,在距地铁站点大约320m时影响程度最大;3轨道交通对沿线站点住房价格的影响程度具有显著的分市场效应,对郊区市场的影响程度要远大于主城区市场。  相似文献

本文用中国2003-2012年285个地级及以上城市的数据,运用空间计量模型实证分析了产业聚集对环境污染的影响。空间自相关性检验表明,中国城市环境污染存在显著的全局空间自相关性和局部空间集聚效应。空间计量回归结果显示,产业聚集显著加剧了环境污染,表明当前中国产业聚集带来的环境负外部性大于环境正外部性;经济发展水平与环境污染之间存在“倒U”型曲线关系,验证了环境库兹涅茨曲线的存在。最后,提出聚集区改善环境污染的政策建议。  相似文献

Assessing comfort of running footwear reliably is challenging. The purpose of this study was to compare the intra-rater reliability between different assessment types, to calculate intra-individual reliability scores and to evaluate the effect of rater selection based on individual reliability scores on group level reliability. Three assessment types: ranking, Visual Analogue Scale (VAS), and Likert Scale (LS) were provided twice in six separate sessions among 30 participants, who assessed comfort of five shoes after treadmill running. Spearman's rho provided an evaluation of inter-session relative reliability and typical error as a measure of absolute reliability for each assessment type. Ranking (r?=?0.70, 95% confidence interval [CI] 0.61–0.78) yielded the highest relative reliability for overall comfort, followed by VAS (r?=?0.67, 95% CI 0.56–0.75) and LS (r?=?0.63, 95% CI 0.52–0.72), with large-scale overlaps of CIs between assessment types. The same order of assessment types was found for the percentage of reliable raters (r?≥?0.7) with 60% in ranking scale, 47% in VAS and 37% in LS. Forming subgroups corresponding to the intra-individual reliability substantially increased group level reliabilities. Based on measures of relative reliability, an extreme reduction in resolution as provided by the ranking from pairwise comparisons seems to be a valuable tool in footwear comfort assessments if assessment time is of minor importance. No preference can be provided for the two investigated rating scales. Besides the assessment type, a selection of the best raters in additional reliability checks seems to be a prerequisite for further comfort-related studies.  相似文献

Of issue in this paper are the ways in which different forms of narrative may be of value in undertaking research in potentially thorny situations. The project that inspired this paper saw 30 Physical Education and Sport Pedagogy (PESP) Early Career Academics (ECAs) from more than 20 universities across Australasia, North America and Europe, provide narrative accounts of their ongoing academic experiences. From these stories, three letters seeking advice and guidance from leaders in the field were constructed. Following further feedback from the ECAs, the 3 letters were sent to 11 professors in the PESP field with a request to respond, also in letter form. The composite letters and the professorial responses were then the subject of a symposium at an international PESP conference. While the larger project engages with questions of being and becoming an academic in the neoliberal university, this paper is primarily concerned with methodological issues, including our steps and missteps with narrative, inquiry and the field. More specifically, the focus is on narrative as both the method and phenomena of study. As such, we consider issues associated with using dialogue as data, the provocation of participants, as well as both the presentation and representation of data and the relative power of the participants. In doing so, we critically engage with issues of anonymity (or lack thereof), the practice of ‘researching up’ and finally reach the conclusion that the careful approach to data generation, treatment and presentation necessitated by this project, should be a more regular feature of all qualitative inquiry.  相似文献

In this article we propose a theoretical framework for narrative analysis that gives voice to objects in sport organisations. Despite considerable interest in the symbolic and mnemonic potency of some sporting objects – most notably memorabilia – many organisational objects go unnoticed, whilst little attention has been paid to methods for gathering stories from inanimate objects. We suggest that material objects in sport organisations participate in narrative production and therefore constitute a rich investigative site. We adopt a post-social approach to narrative methodology where objects are recognised as non-human actors in organisational sense-making, not as narrative repositories that ‘contain’ stories and memories. A three-domain research framework is developed recommending an approach to eliciting an object narrative within a sport organisation. First, object materiality exposes the significant networks of forces, materials and people – and therefore episodes and actors – that engage with and through objects. Second, since people and objects are enmeshed in sequenced, workplace activities, object practice allows organisational agents to define what stories objects can tell whilst objects reciprocally bound the scope of human performance. Third, object biography provides a strategy to map the connections and transitions that occur over the lifecourse of an object, which reveals a changing web of organisational relations.  相似文献

摘要:我国训练理论研究水平仍处在经验阶段,训练理论的治理迫在眉睫。运用文献资料法、逻辑法、时序法等研究方法,以科学技术哲学与复杂性科学为研究视角,从方法论层面试厘清训练理论研究中所出现的问题,以及未来研究趋向等问题。研究认为复杂性是认识训练规律的路径、科学理性是提升训练理论着眼点、学科交叉性是促进训练理论增长点、非线性是促使训练理论研究转型、整体性是表达训练理论的要义。通过提出超越传统意义上的方法论纲领,以期加快竞技体育治理体系和治理能力的现代化,适应国家竞技体育发展战略的需求;希冀训练理论对现代训练实践的要求做出科学地解释与说明,实现训练理论在实践中的应用性和操作性。  相似文献
