蒙藏关系下的文化变迁和民族认同——以青海省河南蒙古族为例

青海省河南蒙古族与藏族交错而居,两个民族长期相互接触,由于族体规模上的差异和自然条件的原因,在文化传播中主要表现为蒙古族对藏族文化的采借和适应,以致从外部特征似难将当地蒙古族从藏族中分辨出来。但细加考察,蒙古族的客观认同和主观心理归属感仍然清晰可见。在融洽的民族关系中,蒙藏之间仍然保持着融而未合、和而未同的特点。

转型中的康区藏族村寨--丹巴县梭坡乡莫洛村考察报告

本文作者考察了四川藏区丹巴县梭坡乡莫洛村社会经济发展的历史与现状 ,发现历史上这一康区藏族村寨是相对独立的经济文化单元 ,单元内生态资源互补、劳力合作、经济互助、婚姻内部流动 ,并曾在外力的影响下不断地进行过变革与调适。现今 ,西部大开发战略和天然林保护、退耕还林等系列工程的实施又将打破这个传统经济单元或文化圈子 ,把小圈子纳入到更大的圈子里 ,莫洛人在困惑与希望中不断地调适自己 ,寻找出路     

阿拉伯伦理学

伊斯兰教前阿拉伯人的伦理道德是由他们生活的自然条件和沙漠社会所决定的 ,是一种不自觉的自然状态 ;阿拉伯人接受伊斯兰教信仰后 ,在人生观、宇宙观、生死观等诸多意识形态领域内的认识发生了重大的变化 ,发生了质的飞跃 ,这时候的伦理道德是一种自觉的理性表现。伊斯兰的基本信仰———确信真主及其使者———就成了伊斯兰道德的基础 ,一切言行都要按照真主的命令认真去做。阿拉伯伊斯兰伦理在道德与行为 (工作、弃恶从善、履行诺言等 )、道德与修养 (容忍、宽恕、平等、民主等 )、主张男女平等、维护妇女权益以及与现代文明关系诸多方面 ,都表现出了它独有的特征

回族群众在花儿会上,不同于日常世俗生活的表现说明,花儿会是回族社会生活中二元结构下的特定时空。在这个特定时空里,回族群众完成了角色转换,以弥合现实生活和精神心理上的矛盾。     

信仰变异与民族特征--卡力岗回族民族特征浅议

化隆卡力岗山区的藏族由于改奉了伊斯兰教而随了回族,因此其民族特征发生了根本性的交化,使他们重新确立了以伊斯兰文化为主导的价值取向和终极目标,形成了新的思维方式、行为规范、生活方式和风俗习惯,支撑着这个民族生活大厦的过去、现在和未来,而伊斯兰文化则成为他们赖以共同奋斗的精神纽带。     

An Examination of How Supervisors Influence Their Subordinates to Engage in Environmental Behaviors

Employee engagement in environmental behaviors is an important topic in operations management. Drawing upon stakeholder, commitment, and organizational support theories, this study creates and tests an empirical model of how store managers (i.e., supervisors) influence their direct reports (i.e., subordinates) to become engaged in environmental behaviors. Based on a dataset derived from supervisors and their subordinates who are employed at the same grocery store location across a large retail grocery chain, we test our study's nomological model and find support for the linkages proposed. Key research and managerial implications are discussed.     

Customer Use of Virtual Channels in Multichannel Services: Does Type of Activity Matter?

Many firms have recently adopted virtual channels, based most notably on the Internet and the phone, to complement the delivery of services to their customers by their existing physical facilities. The success of such multichannel (MC) strategies relies on the alignment of service design decisions—namely those concerning the allocation of service activities to virtual channels—with customers’ MC behavior. Although prior studies have looked at the intensity with which customers use virtual channels, they have not addressed virtual channel use for different types of service activities. In our study, we investigate whether customers’ use of virtual channels for MC services varies with the type of service activities they engage in, and if so, in what way. In doing so, we address two objectives. First, we investigate the impact of accessibility to the physical channel on the degree of use of virtual channels (Internet and phone, aggregated) for different types of activities. Second, we look at channel preferences (Internet vs. phone) for different types of activities when customers do resort to virtual channels to conduct activities. To address our objectives, we develop and test hypotheses regarding customers’ use of virtual channels based on the match between activity attributes (complexity and volume) and channel attributes (access efficiency, interface efficiency, interface richness). Using data from a MC bank, we find that the impact of accessibility to physical channels (specifically, customer distance) on customers’ use of virtual channels, as well as the relative use of Internet versus phone, depend on the type of activities.     

单指标非参数期权定价——改进的非参数定价方法

本文建立一种改进的非参数期权定价模型,称为单指标非参数期权定价模型。相比现有非参数回归期权定价模型是期权价格关于各个因素的多元回归函数,本模型通过变量变换把期权价格多个因素指标转换为一个综合变量——单指标,得到期权价格关于单指标的一元非参数回归方程。改进的模型实现了多元非参数期权定价模型的降维和简化了模型计算;还通过多个期限期权的单指标组合解决了非参数估计的样本数量问题;以及通过期限平滑解决了现有非参数定价模型中的日历效应问题。选取上证50ETF期权数据实证分析表明,无论是样本内的估计结果还是样本外的预测结果都比传统的Black-Scholes模型、半参数Black-Scholes模型和多元非参数回归期权定价模型估计效果有提高。     

气候变化背景下的知识产权国际保护之争

在气候变化与知识产权的问题上,厄瓜多尔等发展中国家在2013年6月至2014年10月的TRIPS理事会议中阐述了修订TRIPS协议的意见以求能够最大限度地获取无害环境技术及其产品,但美国等发达国家坚决拒绝修正TRIPS协议,认为非知识产权因素是妨碍发展中国家应对气候变化的主要原因。双方产生分歧的原因不仅在于对各自国家利益的诉求,也在于TRIPS协议和无害环境技术自身因素。考虑到人权保护的需要和当前处于知识积累阶段的现状,应当以技术转让重于技术创新的方式适应和减缓气候变化,修订TRIPS协议以帮助发展中国家获取无害环境技术及其产品。
