救生艇中的生存：哈丁的南北政治观述评

救生艇理论是加勒特·哈丁（Garrett Hardin）所提出的有关全球环境恶化背景下的南北政治观。哈丁把南北国家（穷国和富国）隐喻为漂流在大海上的救生艇。当穷国的救生艇上的人处于危机状态向富国的救生艇求救时,哈丁认为,最理性的做法就是独自离去,谁也不救。以这个隐喻模型为依据,哈丁围绕南北关系论提出了反援助观,质疑和批评了世界银行的成立和所谓的绿色革命,阐述了执行关门主义移民政策的必要性与合理性。     

Why Don't More Students Major in IS?

The large increases in the number of information systems (IS) majors about 10 years ago have been matched by equally large decreases in IS enrollments over the last few years. This article addresses the question of why students choose any major in general, and why students no longer choose to become an IS major in particular. We used a validated survey instrument and the responses from 163 students to examine this question in detail. Not surprisingly, we found that "genuine interest" in the subject was the most salient factor affecting the decision to major in IS. More surprising were what factors did not appear to influence this decision—for example, the promise of good job salaries, job security, the advice of others, or even the image of those who become IS professionals. Students seem aware that information technology employment opportunities exist; if job and salary issues contribute to choosing majors  other than IS , it is due to the perception of an unfavorable work/salary ratio for our field rather than one of job security or availability. That is, the amount of work to get an IS degree (the perception of harder-than-average courses) combined with (for many students) the perception of an undesirable amount of continuous training to keep an IS career just do not seem to balance with salary levels. These findings have important implications for the recruiting efforts of IS faculty seeking to attract more IS majors.     

Play to win! Using games in library instruction to enhance student learning

Research has shown that educational games can have positive impacts on student learning and motivation. The success of a game played in a library instruction class depends on the type of game selected, the development of learning outcomes, and the flexibility of the librarian during class. This article explains the benefits to students and librarians of using games, discusses the development and use of a Jeopardy-style game, and provides practical tips for librarians interested in developing and incorporating games into one-time library instruction sessions.     

“I Can Air My Feelings Instead of Eating Them”: Blogging as Social Support for the Morbidly Obese

The morbidly obese, defined as people who are 100 pounds or more overweight, are the fastest growing population among the obese. They often live with health risks, face discrimination, and lack traditional social support. This article explores the use of weight loss blogs by the morbidly obese (N = 50) and argues that blogging provides invaluable computer-mediated social support for them in four ways: (a) it allows for empathy; (b) it ensures accountability to others; (c) it provides venting and advice seeking; and (d) it shares validation of the weight loss experience. Additionally, the article argues that social support scholars must move beyond chat rooms and message boards as media and explore more media-rich environments such as blogging and social networks.

Sexual Harassment as [Dys]Functional Process: A Feminist Standpoint Analysis

Researchers have approached the study of sexual harassment as though it were dysfunctional. However, a feminist standpoint theory analysis would suggest that it functions differently for men and women. A study using discussion groups and stimulated recall interviews was conducted in a large health care organization. A thematic analysis revealed a primary theme of sexual harassment as a [dys]functional process. For the male participants, sexual behavior served as a coping mechanism for stress, as a form of therapeutic care, and to create and demonstrate camaraderie. For the women participants, sexual behavior tended to be either nonfunctional or dysfunctional. They did not associate it with stress reduction, therapeutic touch, and viewed group camaraderie as a means of prevention. Implications are discussed.
