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。     

Impact in the school system of a strategy for identifying and selecting academically talented students: the experience of Program PENTA‐UC

The study explores the consequences, for participating schools, of the implementation of a system for the identification and selection of academically talented students, in the context of an extracurricular enrichment program operating at Pontificia Universidad Católica de Chile. The participants were 73 students, 50 teachers, and seven members of the school administration, in seven schools. Data were collected through interviews and focus groups. The results indicated that the identification and selection processes have mostly positive effects on teachers and students. Some potentially negative effects were also detected for the classmates of the talented students, which relate mainly to the manner in which information was handled. Possible implications of these findings for this program for talented children and other similar programs are discussed.     

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。     

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.     

对基因选材的认识

射频识别技术RFID在体育中的运用

RFID技术全称为射频识别技术,英文为Radio Frequency Identification。其在体育领域的应用早有先例,2006年的足球世界杯赛就使用了这种RFID门票,在高尔夫、田径等体育运动中的运用也取得了良好的效果。本文旨在通过对RFID技术原理的介绍,分析其在体育领域的运用现状和开发前景,引起国内体育学界对这项技术的认识和进一步研究运用的开展。     

排球比赛过程风险控制研究

排球比赛风险是指比赛过程中导致本方技战术发挥失常、心理不稳定的各类不可控因素和突发性事件,探讨对比赛风险的控制对于球队获取胜利具有重要意义。通过构建风险识别体系和风险应对体系,并将其运用于高水平球队的训练与比赛,可有效降低比赛过程中各种风险对球队在心理稳定和技战术发挥的危害程度,从而增加制胜概率。     

考虑耦合效应的海上通道风险因素识别

为保障海上通道安全,针对海上通道安全的影响因素较多且相互关联的特点,提出一种考虑耦合效应的海上通道风险因素识别方法。将二元语义应用到专家问卷的语言评价信息,并将2-可加模糊测度扩展到二元语义环境,完成对所有风险因素的识别分析。案例分析结果为:在中欧海上通道风险因素中,对单风险因素进行分析后得出影响最大的两个因素是气象水文海况和海上犯罪威胁,对任意两个因素之间的耦合效应进行分析后得出耦合效应最强的两组风险因素是气象水文海况和通航地理条件以及气象水文海况和通道船舶密度。     

基于AIS数据的船舶排放估测模型与实船验证

为提升船舶能耗和排放估测的准确性和灵活性,提出面向船舶自动识别系统(automatic identification system, AIS)大数据的完全自下而上的船舶能耗和排放估测新方法。该方法视船舶为一种基于船舶航迹的线排放源,在构建船舶网格化轨迹模型的基础上,考虑每个网格航段的持续时间和发动机负载,实现船舶能耗和排放的精细化建模,统一船舶排放总量和空间分布计算。实船应用表明,该方法可提供更加准确的船舶能耗估计,并可灵活计算各种航行状态、船队规模和时空尺度的能耗和排放清单。
