验证性因素分析是依据一定的理论对潜在变量与观察变量间关系做出合理的假设并对这种假设进行统计检验的现代统计方法。本研究采用LISREL软件对某次数学考试的结构进行了检验,试卷设计方案基本得到了验证,显示了较好的结构效度。     

Unpacking the inequality among Turkish schools: Findings from PISA 2006

The study investigates the effects of certain school characteristics on students’ mathematics performances in Turkey in the PISA 2006 while controlling for family background and demographic characteristics. Three models of Hierarchical Linear Modeling (HLM) are constructed. The results reveal that 55% of the variance is attributable to between-schools and the remaining 45% to individual student characteristics. About two-thirds of the 55% is explained by selectivity in admissions, time to study mathematics and students’ SES, gender and the geographical region. The findings are interpreted to explain why Turkish schools differed greatly in average student performance in PISA 2006 by using the conceptual efforts on school quality factors and family background characteristics.     

Current status of cadaver sources in Turkey and a wake‐up call for Turkish anatomists

Persisting difficulties in body procurement in Turkey led to the acquisition of donated, unclaimed, autopsied, and imported bodies regulated under current legislature. Yet, no study had investigated the extent of the on‐going cadaver problem. This study was aimed to outline cadaver sources in anatomy departments and their effectiveness by means of an online survey. Additionally, official websites of each department were investigated regarding any information on body donation. Unclaimed cadavers (84.8%) were the major source for anatomy departments, followed by donated (50%) and imported cadavers (39.1%). Foundation‐based medical faculties were more likely to import cadavers (P = 0.008). There was a moderate increase (r_s = 0.567; P = 0.018) in donation registrations to our department after 2000. The departments in cities with significantly higher City‐Based Gross Domestic Product measures (US$9,900 vs. US$16,772, P = 0.041), frequencies for mid‐ or high‐school graduates (30.4% vs. 31.3%, P = 0.041), and frequencies for under‐ or post‐graduates (13.1% vs. 15.8%, P = 0.24) had managed to use donated cadavers. Anatomy departments’ major reasons for using unclaimed cadavers were education (45.9%), unclaimed cadavers being the only source (24.3%), and receiving inadequate donations (21.6%). Nine out of seventy‐four departments (12.2%) provided information regarding body donation on their websites. Body procurement remains as a serious problem in Turkey and it is apparent that current legislature does not provide a sufficient cadaver inflow. Similarly, anatomy departments’ effectiveness in public awareness of body donation and support in the National Body Donation Campaign seems questionable.

Ultras in Turkey: othering,agency, and culture as a political domain

Abstract

Football administrators and non-fans or non-ultra fans in Turkey tend to posit ultras as either the ‘fire of the show’ or write them off as instruments of violence guided by irrationality. These two stances are the two sides of the same coin which points to a fascination/fear discourse that serves to produce ultras as the perfect other. The financially powerful actors of football tolerate and accommodate ultras so long as they don’t challenge dominating commercial or political interests. This relegates ultras to the supposedly innocuous realm of culture divorced from politics, especially in the aftermath of the Gezi Uprising of 2013. However, through organizations like the Fans’ Rights Association and in their everyday practices of fandom, ultras reject subjectivities assigned to them by the fascination/fear discourse, they agentively engage with their own spectacularization and othering as well as the legal or administrative efforts to contain and confine thesm.     

基于专利和科技论文的技术机会识别研究——以金属3D打印技术为例

主要基于Web of Science科技论文和Derwent专利文献,利用SATI、SPSS等分析工具,提取文本关键词并构建相异共现矩阵,采用多维聚类方法识别研究热点主题。在继承和发展Naoki Shibata技术机会理论的基础上,通过对比科技论文和专利文献研究热点主题的差异来识别金属3D打印的技术机会。研究得出,科技论文和专利文献分别有4个研究热点主题,识别了两大类共4个技术机会。首次基于专利和科技论文研究金属3D打印的技术机会,开拓了金属3D打印的研究视野,对金属3D打印行业的企业战略决策具有指导作用。     

中小企业技术联盟成员之间信任、关系承诺与合作绩效——基于浙江地区产业集群实证研究

以浙江部分地方产业集群中小企业技术联盟为研究对象,通过问卷调查探讨联盟成员间信任对关系承诺和合作绩效的影响.结果显示,(1)组织信任与个人信任存在着相互正向影响;(2)组织信任通过关系承诺对合作绩效的间接影响明显高于其直接影响,个人信任对合作绩效存在着显著的直接影响;(3)联盟成员在技术合作过程中更关注短期目标.     

Attentional focus effects on sprint start performance as a function of skill level

Abstract

Several researchers have demonstrated that an external focus of attention (about movement’s effects) during movement execution allowed better performances and learning of various motor tasks than an internal focus of attention (about movement itself). However, attentional focus effects have not been studied in tasks requiring explosive actions preceded by fast reaction time to a signal, such as a sprint start. We hypothesised that the beneficial effect of external focus of attention would be observed in the different stages of the sprint start (i.e. reaction time, block clearance and running) for both expert and novice sprinters. Novice and expert sprinters performed sprint starts followed by a 10 m sprint under three conditions: external focus instructions; internal focus instructions; and neutral instructions. The reaction time and the running time were significantly shorter in the external focus condition than in the internal focus condition, for both expert and novice participants. These results confirm the beneficial effect of an external focus of attention on the speed of movement execution. Moreover, they revealed that attentional focus influences movement preparation. Several hypotheses are proposed to account for these results, with reference to the processes that could be responsible for the observed effects.
