The aim of the study is to examine motivations for practicing physical activity on holiday. In particular, the objective is to compare home habits to holiday experiences and identify differences and commonalities in individuals’ attitude towards physical activity. The methodological approach is to conduct a survey among tourists during a holiday stay by employing a self-administered questionnaire. Findings identify three motivational factors (Decompress, Performance and Shape) and a cluster analysis reveals the coexistence of four different profiles of physical activity performers (Shapers, All-around Pursuers, Sport Performers and Decompress Seekers). Results show diffuse distinctiveness of motivations for practicing physical activity on holiday compared to the motivations for practicing it at home. Specifically, Decompress motives increase and Shape motives decrease. The study contributes to deepen the knowledge on consumer behaviour in leisure and holiday and provides useful insights to destination managers and policy-maker to address the sport tourism market.  相似文献

Stimuli that predict the occurrence of aversive events come to elicit conditioned analgesia. Experiments 1A and 1B examined the possibility that conditioning can inhibit analgesia when stimuli are paired in a backward fashion with a shock US (Pavlovian CS- s). Analgesia conditioned in response to shock context exposure was reversed during the CS- (light) presentation after four sessions. The ability of the CS- to function as a conditioned inhibitor of analgesia was then evaluated in both summation (Experiment 1A) and retardation-of-acquisition testing (Experiments 1A and 1B). The results support the conclusion that a stimulus presented after shock in a backward fashion comes to be a conditioned inhibitor of analgesia. Experiments 2A and 2B examined the assumption that the results obtained with our pain sensitivity measure (tailflicking in response to radiant heat) reflect changes in responsiveness to painful input, rather than a general motor inhibition or general insensitivity to sensory input. In Experiment 2A, tailflick responding to painful and nonpainful input was compared in animals receiving either morphine or saline. In Experiment 2B, tailflick responding to painful and nonpainful input to the tail was compared in both the shock and a neutral context. In both experiments, only the painful input yielded changes in responsivity. The results support the conclusion that the alterations in pain sensitivity produced by the CS- for shock represents a conditioned inhibition specific to pain.  相似文献

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted.  相似文献

In this study, 69 women were surveyed who, as a result of a prenatal screening knew they were at risk for carrying a fetus with a disability. Results indicated that most women were referred by their physicians for genetic counseling either because of their age or because of an abnormal blood test. The majority of women indicated they would choose to terminate a pregnancy that tested positive for a disability, but the type of disability of the fetus, either Down syndrome or spina bifida, made no difference in the decision that women believed they would make. The women's intention to terminate a pregnancy appeared to be unrelated to their overall knowledge about disabilities but was negatively related to their knowledge of disability-related services. Although women reported that genetic counseling was helpful, they revealed that they were not given information about future-quality-of-life issues for individuals with disabilities nor provided with the positive as well as the negative aspects of giving birth to a child with disabilities.  相似文献

Information literacy curriculum for third-year medical students at Northwestern University has evolved over several years under the guidance of librarians at the Galter Health Sciences Library. Starting as a series of rotation-specific information resource overviews, initial evaluation and feedback led to the curriculum being developed to include more focused and interactive clinical information sessions with a quiz-based assessment. Future enhancements will include web-based self-directed learning using online tutorials, additional search exercises that mimic the on-the-go clinical environment, and better assessment of the curriculum's impact on students' information literacy and clinical search skills.  相似文献

This article describes the results of a survey of library patrons conducted by librarians and information technology specialists at the Health Science Center Libraries at the University of Florida. The purpose of the survey was to learn if and how library patrons were using smartphones to perform their work-related tasks and how patrons felt the library could support smartphone use at the Health Science Center.  相似文献

Objectives:

The Medical Education Task Force of the Task Force on Vital Pathways for Hospital Librarians reviewed current and future roles of health sciences librarians in medical education at the graduate and undergraduate levels and worked with national organizations to integrate library services, education, and staff into the requirements for training medical students and residents.

Methods:

Standards for medical education accreditation programs were studied, and a literature search was conducted on the topic of the role of the health sciences librarian in medical education.

Results:

Expectations for library and information services in current standards were documented, and a draft standard prepared. A comprehensive bibliography on the role of the health sciences librarian in medical education was completed, and an analysis of the services provided by health sciences librarians was created.

Conclusion:

An essential role and responsibility of the health sciences librarian will be to provide the health care professional with the skills needed to access, manage, and use library and information resources effectively. Validation and recognition of the health sciences librarian''s contributions to medical education by accrediting agencies will be critical. The opportunity lies in health sciences librarians embracing the diverse roles that can be served in this vital activity, regardless of accrediting agency mandates.In response to reported closings of and staff reductions at hospital libraries, the Medical Library Association (MLA) and the Hospital Libraries Section of MLA agreed to study the state of hospital libraries and librarians under the auspices of the Task Force on Vital Pathways for Hospital Librarians. The task force''s Health Sciences Librarian in Medical Education Task Force (METF)* was charged with reviewing the accreditation standards regarding libraries for residency programs and with working with national organizations to integrate library services, education, and staff into the requirements for training medical students and residents.  相似文献
