SUMMARY As distance education courses increasingly move to the online environment, librarians are discovering new challenges and opportunities for reaching distant students. Collaboration with faculty is essential in reaching students who may never enter the library building. One such method of collaboration is librarian participation in online courses through “lurking” in Blackboard and Desire2Learn classrooms and monitoring discussion threads devoted to library research. Advantages such as improved access to students, course content, and assessment data are discussed, as are disadvantages, such as time commitment, varying expectations, and privacy issues. Considerations for librarians interested in “lurking” are outlined. 相似文献

Since 2000, Neil Spiller has been engaged on a ‘long project’: a series of hundreds of drawings that through a potent mix of cyborgian fantasy and Surrealism, imbued with poetry and biotechnology, evoke a psycho-geographical island inhabited by an irascible alter ego, ‘The Professor’. Spiller seeks out in this work ‘an unusual and startling architecture’ that reveals a ‘loving, enigmatic and ragged beauty’. 相似文献

Drawing on dual-system theory, this study examines the role of desire for online group gaming in online social game addiction. By conducting a longitudinal online survey, we show that attitude, anticipated enjoyment, group norm, and social identity contribute to the development of desire for online group gaming. Such desire facilitates habit and self-regulation deficiency, which, in turn, fosters online social game addiction. This study contributes to the literature by theorizing a nomological network of desire for online group gaming on online social game addiction and by offering implications for managing addictive gaming. 相似文献

A crucial challenge in investigating motivated human eating behaviour is to go beyond subjective measures, by developing reliable methods capable of objectively quantifying the dynamic aspects of appetitive motivation. We developed and tested a novel effort-based task (Grab-to-Eat Task (GET)), utilising handgrip force as a motivational measure, to capture eating motivation dynamics throughout consumption. Sixty normal-weight young adults were allocated to one of two hunger state conditions (hungry or satiated) and performed a continuous reinforcement-based task, during which sips of chocolate milk were self-administered with a handgrip force transducer. Motivation was covertly assessed by the magnitude of effort exertion towards each sip. Cumulatively, hungry subjects exerted more effort and consequently consumed more chocolate milk than satiated ones. Effort exertion declined throughout consumption in both groups, with the rate of decline being two-fold greater in hungry subjects. Furthermore, effort exerted in the initial stages of consumption predicted subsequent intake. Present results fit in the theoretical framework of reward-related motivation and suggest that the developed paradigm is sensitive to eating motivation dynamics throughout consumption and to differences in eating motivation related to hunger state. Further validation, ideally involving functional neuroimaging, would be imperative. In the future, this paradigm could be used to investigate eating motivation dynamics in various populations, conditions and food products. 相似文献
