Effect of one type of need complementarity on marriage partner's conformity to one another's judgments.

The hypothesis tested was that when the husband's need to receive affection (Succorance) is similar in strength to the wife's complementary need to give affection (Nurturance), the tendency of spouses to be influenced by one another will be relatively high. 55 paid volunteer couples filled out a forced-choice need questionnaire. Husbands' Succorance scores and wives' Nurturance scores were split at their medians, and couples were classified according to the 4 combinations of high and low scores. Social influence was tested on a visual discrimination task. It was found that this type of complementarity was directly related to acceptance of the spouse's judgments by husbands, but not by wives. As expected, conformity was not related to complementarity based upon husband's Nurturance and wife's Succorance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

集成主被动式安全带的性能评估及优化分析

针对高级驾驶员辅助系统（ADAS）功能多、集成度低的情况,提出了将可逆预紧式安全带与车道偏离预警系统、前方碰撞预警系统和疲劳驾驶监测系统集成为一体的集成式主被动安全系统。在探讨了该集成系统的工作原理和控制策略基础上,通过开展志愿者实车道路实验研究了前方预警系统的碰撞时间阈值、安全带预紧力以及安全带预紧时产生的噪声三个因素对乘员主观感受的影响。对志愿者的主观评价和实验数据的对比分析表明：该集成系统的控制策略逻辑合理,在各个工况下能够主动触发以提醒和约束乘员;但是初期由于预警提醒的频次过高和噪声较大影响了乘员的驾驶体验。经过降低预警系统碰撞时间阈值和优化调整安全带的传动结构,提高了乘员的驾驶体验。该集成式主动安全系统可有效地辅助驾驶员驾驶,且满足乘员的主观可接受度。     

自愿计算中重叠网络拓扑对面向结点能力的非集中式调度方法的影响分析

自愿计算在大规模计算模式中正在扮演着越来越重要的角色．目前的自愿计算环境大多是专用和集中控制的,因而存在着某些可用性和可扩展性的问题．最新的研究提出了基于对端重叠网络的自愿计算环境构造方式,通过在各参与结点间建立更灵活的连接形成对端重叠网络来实现计算资源更灵活、有效的共享．面向结点能力的调度方法是为适应这一变化而提出的自愿计算中的一种非集中式资源调度方法,具有简单易行的特点．这一方法的效果在很大程度上取决于底层的重叠网络拓扑结构．文中建立了相应的理论分析模型,计算了该调度方法在具有不同度均值和聚合系数的对端重叠网络中搜索步长和最终所定位结点能力水平的期望．模型计算通过迭代进行,将时间复杂度控制在O（n^3）．利用3种不同的拓扑生成算法所产生的不同特征的重叠拓扑结构进行了仿真验证．模型的理论计算结果与仿真结果吻合良好,表明在具有较小的聚合系数和较大结点度均值的重叠网络中,面向结点能力的资源调度方法具有更好的效果．     

Daily recovery experiences: The role of volunteer work during leisure time.

This study focused on the role of volunteer work for daily recovery from work. In a 1-week diary study with 166 employees, we assessed the amount of time spent on volunteer work during leisure time, and the recovery facets of psychological detachment from work (i.e., mentally switching off from work), mastery experiences (i.e., pursuing challenging activities), and community experiences (i.e., cultivating relationships) every day before participants went to bed. Results from hierarchical linear modeling (n = 529 days) showed volunteer work during leisure time to be positively related to mastery experiences and community experiences suggesting volunteer work to contribute to successful recovery by creating new resources.

志愿计算中基于贝叶斯定理的信任模型

志愿计算因其开放性、匿名性和动态性得到广泛应用,但同时也对系统的安全性带来挑战.传统认证方式无法满足志愿计算系统的安全性需求,而通过在系统中建立信任机制可以有效解决这一问题.为此,构建一种基于贝叶斯定理的志愿计算系统信任模型VC-trust.依据贝叶斯定理对节点的不确定性行为进行分析预测,根据节点历史交互记录并引入处罚因子和调节函数计算节点信任值,同时利用时间滑动窗口对其进行更新.实验结果表明,在节点行为变化的情况下,VC-trust模型较BTMS模型具有更高的交互成功率.

CAVEAT Exemplar: Participatory Design in a Non-Profit Volunteer Organisation

This paper reports a university course-based case study undertaken with a volunteer organisation. Our goals were to explore the use of participatory design in a non-profit volunteer setting; to reflect on the experience of learning and applying participatory methodologies; and to create a prototype, using off-the-shelf database software, that could become a sustainable organisational information system. We found system design methodologies that stress cooperation and consensus especially appropriate when working with volunteers, who expect control over their work in exchange for their time and effort. The Future Workshop was particularly valuable in developing group insight into work and consensus around system priorities. The study resulted in a prototype which has evolved, through in-house refinement, into a working system.
