论高等教育学生资助对象的认定

高等教育产品属于准公共产品,但各层次、各类别高校、各专业产品公共性是有区别的。个人高等教育选择依据其高等教育的私人产品性质而做出,在现有中国高等教育入学选拔制度下,最能反映高等教育私人产品性质的是各高校及专业选择性指标的高低,这可以从报考志愿拥挤度和录取分数得以反映。高等教育学生资助,首先应依据申请学生所在学校、专业的选择性指标对学生进行分类,实施以政府资助为主或是以市场、学校资助为主。其次应对贫困学生进行分级,学生学习生活每月消费支出（参考最低生活保障标准）、所学专业类型、家庭所在位置（城乡、区域）、学生交纳学费情况、家庭成员职业背景、家庭或成员特殊情况等指标最能反映经济困难程度,应根据这些指标计算出个体的贫困指数,对资助主体实施不同级别的资助。再次应完善学生资助对象认定路径,要加大非诚信者的机会成本、建立资助信息平台、完善市场化资助主体认定资助对象的相关政策、细化资助对象认定的具体措施。

基于时空数据融合的古城区停车需求模式识别

在城市机动化快速发展背景下,南京、苏州等城市的古城区往往因为建筑保护等原因加剧机动车停车供需矛盾.探寻各种缓解停车问题对策的基础是准确掌握实际停车需求.实践中,传统依赖人工调查采集或者停车场抽样数据的方式存在精度维度较低以及不可持续等缺陷.研究以苏州为实证对象,利用交通卡口等多源数据,提出一套目标区域停车需求估计,以及...     

Cultural Identification and Religious Identification Contribute Differentially to the Adaptation of Australian Adolescent Muslims

Australian Muslims are generally perceived as a devalued group in Australia and the public attitudes towards them are generally negative. This context raises questions about belonging and adaptation among Australian adolescent Muslims. The current study investigated how adolescent Muslims relate to their heritage culture, religion, and Australian culture, and which of these three factors is most important to adolescent Muslims’ psychological and socio-cultural adaptation. The study employed a mixed-method design. A total of 321 high school Muslim students (149 males and 172 females) aged between 14 and 18 years completed self-report questionnaires, and a subset sample of 18 students in the same age range, evenly split between males and females, participated in semi-structured interviews. The study revealed a hierarchical pattern of identification among Australian adolescent Muslims, with attachment to their religion being the most important, followed by heritage culture identification and being Australian in third place. Australian adolescent Muslims’ religious identification was perceived overall as more crucial to their socio-cultural and psychological adaptation, than their heritage culture identification or Australian identification. There was an overall modest contribution of Australian identification to adolescent Muslims’ adaptation. This might be connected with the relatively less attachment they show to their Australian identity due maybe to perception of being the target of prejudice, an issue that can be addressed by implementation of prejudice reduction strategies.

An exploration of young professional football players’ perceptions of the talent development process in England

The identification and development of players in English professional football has become an increasingly significant topic of debate given the historical perceived underperformance of the English national team at international tournaments. To enhance understanding of the challenges and barriers experienced by English youth footballers, the authors explore the developmental experiences of English professional football players from different levels of the English football pyramid. Professional players (N = 11) from football clubs in the top four professional divisions in England took part in individual semi-structured interviews, which were analysed inductively using thematic analysis. The data revealed three interrelated themes that were perceived to mediate player identification and development pathways at professional clubs. Pathways for young players to progress and experience first-team competitive football differed when the level of the league that the players operated within was considered, with significant issues also raised relating to the suitability of the under 21 league structure, the importance attached to the educational welfare of young players, and variations in the identification of player attributes. This study sheds new light on the priorities and processes of talent development and education provision in English football.     

感知的企业社会责任对员工创新行为作用机制的实证研究

在经济转型和社会发展进入新阶段,创新成为时代主旋律的大背景下,“如何激发员工创新行为”已成为当前企业人力资源管理实践最重要的问题之一。本研究从责任伦理的视角探讨了员工感知的社会责任(PCSR)对员工创新行为的影响机制。通过对671名的家族企业员工的调查研究发现：(1)PCSR会对员工创新行为产生正向的影响;(2)组织认同、工作不安全感和员工的工作投入在PCSR和员工创新行为之间起着重要的中介作用,PCSR通过影响员工的组织认同、工作安全感和工作投入进而对其创新行为产生影响;(3)本研究把PCSR分为内部和外部两个层面,并对比研究发现员工感知的内部社会责任对组织认同、工作投入和员工创新力的影响效应要显著大于员工感知的外部社会责任。本研究着眼于责任伦理的教化与感知,比较有创见性的提出责任伦理的感知和教化等软性因素是驱动创新的重要源动力和管理落脚点,丰富了关于PCSR领域的研究,也为管理实践中“如何调动员工的创新行为”提供了一个新的有益思路。     

基于二次匹配的指纹识别方法的研究

在前人的研究成果的基础上,对指纹识别的各个过程,包括指纹图像预处理、指纹图像特征点提取、指纹匹配等相关算法进行了研究。特别是在指纹图像匹配阶段,为了得到较好的效果,采用了两次匹配的过程,第一次匹配使用传统的基于特征点的匹配方法,能够迅速地去除差距很大的图片和效果较好的匹配图片,而第二次匹配使用了基于可变界限盒的串距离匹配方法,这种方法能够更好地适应指纹图像的非线性形变等情况。通过这样的两次匹配,能够得到比较满意的匹配结果。
