A simplified proof of a theorem on the difference of the moore–penrose inverses of two positive semi–difinte matrices

Simplified proofs are given of a standard result that establishes positive semi–definiteness of the difference of the inverses of two non–singular matrices, and of the extension of this result by Milliken and Akdeniz (1977) to the difference of the Moore–Penrose inverse of two singular matrices.     

Souls on Ice: Incorporating Emotion in Web-Based Education

SUMMARY

Emotions have been neglected in education and online education, in favor of a heavy emphasis on cognition and rationality. This article explores the significance of emotion in learning and how recent research is identifying some pathways and dynamics in the way emotions impact on learning and on web-based learning. Online learners have not been considered as “emotional beings” and web-based education has not addressed this dimension in any significant way. A constructivist, emotionally-oriented (CEO) model of web-based education is introduced which emphasizes safety, challenge, and new thinking, and offers several strategies to enhance the emotional experience of learners.     

修复与强化:美韩同盟关系的新发展

1953年10月美韩同盟建立至今,两国关系起伏不断,曲折发展。2008年李明博上台后,美韩关系进入"修复"期,2010年3月的"天安号事件"和11月的延坪岛炮击事件为两国关系注入了"固化剂"。美韩同盟的强化是多重因素综合作用的结果,其中既有中国崛起的宏观背景,也与美韩两国出于国家利益的战略选择密切相关,突发事件成为美韩同盟强化的直接动因。美韩同盟关系的新发展对中国东北亚安全利益产生了一些不利影响,如何应对当前的被动局面,有效化解中国与周边国家的矛盾,事关中国和平发展的大局,值得我们认真思考。     

The Role of Positive Psychology in Enhancing Satisfaction,Motivation, and Productivity in the Workplace

Abstract

Positive psychology offers scope for enhancing satisfaction, motivation, and productivity in the workplace. Wiegand and Geller (2004, this issue) point to a number of strategies to enhance individuals' success orientation and conclude their discussion with the actively caring model which appears to be a useful means of representing pivotal facets of a positive and supportive workplace climate. The discussion in this article extends some of the concepts presented in their paper, adapts a model of motivation to develop the Occupational Motivation and Engagement Wheel, and also further discusses some particularly key strategies alluded to by Wiegand and Geller. These include a discussion of workplace resilience, authoritarian versus authoritative leadership/management styles, motivating workplace climates, personal bests, staff morale, flow in work, the value individuals attach to tasks and outcomes, and the centrality of relationships in the performance context. The article concludes with a multi-level “broaden and build” framework for enhancing satisfaction, motivation, and productivity in the workplace.     

Applying the ‘Experience-Near’ Principle To Research: Psychoanalytically Informed Methods1

This article is about how to preserve the vitality of the meaning conveyed to social science researchers by participants. I use the example of a qualitative, psycho-social project on the topic of how women's identities change when they become mothers for the first time. Psychoanalysis was used and adapted to understand both participants' and researchers' experience, and the relation of these to each other. I describe two psychoanalytically informed research methods, free association narrative interviewing and infant observation, and give examples of how, separately and together they can go beyond a text-based method and conceptualise identities in ways that avoid reproducing assumptions of rational, unitary, discursive subjectivity. In assessing how well the two methods worked, I focus my discussion on the observation method using four themes: dimensions of time, embodiment and practices, spatial sensitivity and multiple positioning, and how knowing is accomplished in research.

崛起的中国与国际组织：一种互动关系的分析

国际组织在国际事务中日益活跃是当今世界全球化浪潮的一个重要表现和特征。每个国家的兴衰成败已与国际组织密切相关。中国的崛起、中国国际地位的重要性和特殊性,对中国参与国际组织以及国际组织对中国的认同和接纳,产生了不容忽视的重要影响。当前,中国与国际组织已形成相互影响、彼此促进、良性互动的态势,这对中国的国家发展和国际社会的和平与发展都具有重大意义。     

Generalizability of Gottman and Colleagues' Affective Process Models of Couples' Relationship Outcomes

The generalizability of Gottman et al's. (1998) affective process models was examined using a community-based sample of 85 married or cohabiting couples with at-risk backgrounds. Predictive associations between affective processes assessed at about age 21 years and relationship status and satisfaction approximately 2.5 years later were examined. The major findings of Gottman et al. failed to replicate. In particular, men's rejection of their partners' influence, the lack of men's deescalation of partners' negative affect, and women's negative start up were not predictive of relationship status. Further, differences in affective processes were found when comparing discussion sessions of the men's versus the women's chosen topics. The findings suggested that the validity and utility of the affective process models need further investigation.     

两种情感概念：涂尔干与柏格森的情感理论比较--兼论二者对情感人类学的启示

涂尔干的消极情感理论触及了情感人类学的根本议题,即个体情感和集体情感的关系问题,同时铺陈出情感人类学的核心议题,即个体情感如何对抗集体情感的问题。柏格森的积极情感化解了这类二元论问题,有利于我们重新思考情感人类学理论的进一步发展。     

微博语篇中的态度特征研究--基于话题“哈尔滨浓雾”的评论

作为新兴社会化媒体,微博自推出以来迅速成为流行的通信平台。借助微博,用户可以即时发表简短信息来描述、更新和分享他们当前的状态以及对事情的态度和看法。文章以“情感‐判断‐鉴赏”为分析框架,以“哈尔滨浓雾”为微博议题,提取新浪微博中的微博文作为研究对象,以微博用户对此微博文的评论作为语料,分析评论中的态度资源。统计分析显示：情感资源多以显性方式表达,反映出网络语言具有生动形象化和直观化等特点;与情感和判断资源相比,鉴赏资源中多以隐性方式表达其否定的态度意义。在基于事件的微博中,用户通过情感、判断、鉴赏话语策略传递对评价对象的态度倾向,多以隐性方式表达对事件的否定态度,但对实现人际意义却采取积极介入的语言策略。
