This qualitative longitudinal study focuses on analyses of journals written by 31 sixth grade students who participated in the Chapel Buddy program. The Chapel Buddy program is a developmental mentoring program that pairs sixth graders with kindergarten students. Mentors responded to guided writing prompts three times during the course of the year. Prompts were designed to encourage mentors to explore their role as mentors and their understanding of the mentor–mentee relationship. Results indicated that the program presented a rich, experiential learning opportunity for the sixth graders to develop a relationship with a younger child, to reflect on what it means to be in a helping relationship, and to examine their experiences as “big kids.” Sixth graders varied in their ability to successfully engage and manage their kindergarten mentees, which in turn meaningfully affected the mentors’ satisfaction. Strategies to maximize the educational value of developmental mentoring programs with younger mentors are discussed.  相似文献

This article describes the legal research boot camp offered at the University of Arizona James E. Rogers College of Law. It is an intensive, one-week course offered the first week of the summer break to prepare students for their summer clerkships. It is also a vehicle to teach law librarianship students how to teach legal research.  相似文献

In order to evaluate a new Clinical Medical Librarian (CML) service at Preston Medical Library in Knoxville, Tennessee, the three departments participating in the service were surveyed and interviewed. Participants in the study shed light on how much impact the attendance of a librarian at rounds and other meetings has had on their patient care decisions as well as their use of the library. Overall, the CML service has been well received by residents and faculty and will continue to serve at least these three departments.  相似文献

The article examines shifting patterns of ownership for cable programming services from 1994 to 2003. In these years, vertical integration in the cable industry declined, as cable's multi-system operators divested equity in programming services. Meanwhile, broadcast network-owning media conglomerates invested heavily in cable, tripling their holdings among the top 20 most fully distributed cable channels, as well as launching and acquiring dozens of additional, less widely distributed channels. In light of the Federal Communications Commissions' recent attempts to revise rules regarding television ownership, the author argues that while vertical integration has declined, the market power of the broadcast networks has grown by means of a new kind of horizontal integration that reaches across broadcast and cable channels. This shift is reshaping cable as a market which, despite growing product differentiation, is trending toward less competitive conditions that are akin to the broadcast oligopoly. This article shows that these broadcast-cable alliances contributed to the development of the new synergistic practice of repurposing.  相似文献

Objectives

The aims of this study were to: 1) establish whether infection control professionals (ICPs) who had access to and utilised medical librarian services for evidence‐based medicine (EBM) research perceived this assistance to be useful and 2) to establish whether ICPs who used electronic or hard copy resources for EBM research perceived that those resources had a significant impact on their work.

Methods

Convenience sampling was used to collect quantitative data via a questionnaire. Study participants were members of South‐west and Western chapters of the Association for Professionals in Infection Control and Epidemiology. There were 264 questionnaires distributed in this study; 179 participants completed the questionnaire. The response rate for eligible respondents was 59.5% (157).

Results

Results indicated 56.7% (51) of the ICPs with librarian access reported requesting assistance from their work facility librarian. In reference to locating infection control information, 77.9% (95), 87.3% (124) and 93.3% (138) of ICPs found textbooks, journals and the Internet ‘very useful’ or ‘useful’, respectively.

Conclusion

Study results indicated ICPs who used the assistance of medical librarians and/or hard copy or electronic resources for EBM research perceived such sources to be valuable for obtaining infection control information.  相似文献

Two-year-olds use the sentence structures verbs appear in--subcategorization frames--to guide verb learning. This is syntactic bootstrapping. This study probed the developmental origins of this ability. The structure-mapping account proposes that children begin with a bias toward one-to-one mapping between nouns in sentences and participant roles in events. This account predicts that subcategorization frames should guide very early verb learning, if the number of nouns in the sentences is informative. In 3 experiments, one hundred and thirty-six 21- and 19-month-olds assigned appropriately different interpretations to novel verbs in transitive ("He's gorping him!") versus intransitive sentences ("He's gorping!") differing in their number of nouns. Thus, subcategorization frames guide verb interpretation in very young children. These findings constrain theoretical proposals about mechanisms for syntactic bootstrapping.  相似文献

We examined whether the reason offered for electronic performance monitoring (EPM) influenced participants' performance, stress, motivation, and satisfaction. Participants performed a data‐entry task in one of five experimental conditions. In one condition, participants were not electronically monitored. In the remaining conditions, participants were electronically monitored but the explanation varied. One group was told that they would be electronically monitored but were given no explanation. Another group was told that EPM would be used to research factors associated with performance. In the developmental condition, participants were told that EPM would be used to provide them with feedback to improve performance, and in the administrative condition, participants were informed that EPM would be used to distribute rewards and punishments. Administrative condition participants had higher motivation and performance yet relatively low stress and dissatisfaction levels. Thus, EPM may enhance performance on simple, repetitive tasks without necessarily producing negative outcomes.  相似文献
