Peterson M Harris L;South Australian Health Libraries Consortium 《Health information and libraries journal》2002,19(2):78-83
The establishment of the South Australian Health Libraries Consortium led to the development of the SALUS project which enabled the online delivery of core health, clinical information and bibliographic databases with full-text resources across South Australian government health services. This was the first venture of Australian health librarians to create an online consortium. This article discusses the policy and management issues surrounding the implementation of the SALUS project and its influence on the evolution of the health Libraries Consortium over several years. Lessons learned during this process included: the necessity to plan well ahead yet to remain flexible in implementing those plans, to avoid procedure becoming more important than improvization during planning, to be willing to take well judged risks on occasions, and to be fully aware of changing circumstances in the project's funding and political environment. The importance of securing influential advocates outside of the participating libraries to support continued project funding is also considered. 相似文献

AbstractThe object of this study is to assess Texas A&M University (TAMU) students/faculty/staff members’ use and awareness of the Libraries’ free document delivery and interlibrary loan service, branded as “Get It For Me.” Since 2010, we have continued to see a decline in new user registrations each year. Previous Get It For Me user surveys conducted in 2003 and 2011 indicated that the overall satisfaction of registered users was high and customer feedback gleaned from these surveys was used to initiate a number of service improvements. But what about the large percentage of the campus community who do not use the Get It For Me service? Are they aware of what this service has to offer? If so, why might they choose not to use it? If they are not aware of the service, might they use it if they knew more about how it can assist them in their scholarly endeavors? Instead of only surveying those customers who have used this service, we invited everyone on TAMU College Station campus to participate in the survey. Promoting the service is a vital component of service delivery. 相似文献

Controlled vocabulary and subject headings in OPAC records have proven to be useful in improving search results. The authors used a survey to gather information about librarian opinions and professional use of controlled vocabulary. Data from a range of backgrounds and expertise were examined, including academic and public libraries, and technical services as well as public services professionals. Responses overall demonstrated positive opinions of the value of controlled vocabulary, including in reference interactions as well as during bibliographic instruction sessions. Results are also examined based upon factors such as age and type of librarian. 相似文献

Infant Temperament: Stability by Age,Gender, Birth Order,Term Status,and Socioeconomic Status 下载免费PDF全文
Marc H. Bornstein Diane L. Putnick Maria A. Gartstein Chun‐Shin Hahn Nancy Auestad Deborah L. O'Connor 《Child development》2015,86(3):844-863
Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals. 相似文献

Investigating Change in Adolescent Self‐Efficacy of Food Safety Through Educational Interventions 下载免费PDF全文
Amy S. Beavers Lindsay Murphy Jennifer K. Richards 《Journal of Food Science Education》2015,14(2):54-59
A successfully targeted intervention can influence food safety knowledge, attitudes, and behaviors, as well as encourage participants to recognize their own responsibility for safe food handling. This acknowledgement of an individual's responsibility and capacity to address food safety can be understood as self‐efficacy of food safety (SEFS). This study investigated the impact of a specific educational intervention, Hands On: Real‐World Lessons for Middle School Classrooms, curriculum on SEFS in adolescents and was guided by two research questions: (1) to what extent can an existing food safety curriculum impact students’ SEFS, and (2) to what extent does a relationship exist between changes in self‐efficacy and changes in food safety behavior, particularly when controlling for knowledge gains. A total sample of 424 students across 6 states participated in this study. Teachers were trained to implement the Hands On program in their classrooms and then students were administered a pre‐ and posttest to measure the impact of the program on knowledge, food safety‐related behaviors, and SEFS. The data indicated that there is a strong predictive relationship between SEFS and positive behavior change. Additionally, the Hands On program was effective at increasing students’ SEFS. 相似文献

Research demonstrates that information disseminated and circulated in online forums may have a significant impact on investors and on the securities market. Therefore, an understanding of that environment is critical. This research uses social capital theory as a framework for understanding how information exchange is facilitated in online investor forums. Specifically, it explores whether or not personal experience may generate social capital in the online environment. This work reports on the relationships between sharing personal experience and information sharing and use in three investor discussion forums. Four hundred forty threads containing 2405 posts were analyzed for this study. Thread starter posts and responses were quantified and coded for statements of personal experience. Citations to information sources were also measured. Results demonstrate that explicitly stating personal experience or lack of personal experience affects the quantity and quality of ensuing discussion and information exchange. Possible implications of this work on both the study of online investor forums and the study of social capital are discussed. 相似文献

Research Findings: The transition to kindergarten has important ramifications for future achievement and psychosocial outcomes. Research suggests that physical aggression may be related to difficulty during school transitions, yet no studies to date have examined the role of relational aggression in these transitions. This article examines how engagement in preschool physical and relational aggression predict psychosocial adjustment during the kindergarten school year. Observations and teacher reports of aggression were collected in preschool, and kindergarten teachers reported on student–teacher relationship quality, child internalizing problems, and peer acceptance in kindergarten. Results suggested that preschool physical aggression predicted reduced peer acceptance and increased conflict with the kindergarten teacher. High levels of relational aggression, when not combined with physical aggression, were related to more positive transitions to kindergarten in the domains assessed. Practice or Policy: These data lend support to the need for interventions among physically aggressive preschoolers that target not only concurrent behavior but also future aggression and adjustment in kindergarten. Thus, educators should work to encourage social influence in more prosocial ways among aggressive preschoolers. 相似文献

We examined the effects of concomitant increases in crank rate and power output on incremental arm crank ergometry. Ten healthy males undertook three incremental upper body exercise tests to volitional exhaustion. The first test determined peak minute power. The subsequent tests involved arm cranking at an initial workload of 40% peak minute power with further increases of 10% peak minute power every 2 min. One involved a constant crank rate of 70 rev · min(-1), the other an initial crank rate of 50 rev · min(-1) increasing by 10 rev · min(-1) every 2 min. Fingertip capillary blood samples were analysed for blood lactate at rest and exhaustion. Local (working muscles) and cardiorespiratory ratings of perceived exertion (RPE) were recorded at the end of each exercise stage. Heart rate and expired gas were monitored continuously. No differences were observed in peak physiological responses or peak minute power achieved during either protocol. Blood lactate concentration tended to be greater for the constant crank rate protocol (P = 0.06). Test duration was shorter for the increasing than for the constant crank rate protocol. The relationship between local RPE and heart rate differed between tests. The results of this study show that increasing cadence during incremental arm crank ergometry provides a valid assessment of peak responses over a shorter duration but alters the heart rate-local RPE relationship. 相似文献
