This study focuses on relations between 7- and 9-year-old children’s and adults’ metacognitive monitoring and control processes. In addition to explicit confidence judgments (CJ), data for participants’ control behavior during learning and recall as well as implicit CJs were collected with an eye-tracking device (Tobii 1750). Results revealed developmental progression in both accuracy of implicit and explicit monitoring across age groups. In addition, efficiency of learning and recall strategies increases with age, as older participants allocate more fixation time to critical information and less time to peripheral or potentially interfering information. Correlational analyses, recall performance, metacognitive monitoring, and controlling indicate significant interrelations between all of these measures, with varying patterns of correlations within age groups. Results are discussed in regard to the intricate relationship between monitoring and recall and their relation to performance. 相似文献

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice. 相似文献

The concept of "one-stop information shopping" is becoming a reality at Columbia-Presbyterian Medical Center. Our goal is to provide access from a single workstation to clinical, research, and library resources; university and hospital administrative systems; and utility functions such as word processing and mail. We have created new organizational units and installed a network of workstations that can access a variety of resources and systems on any of seventy-two different host computers/servers. In November 1991, 2,600 different individuals used the clinical information system, 700 different individuals used the library resources, and 900 different individuals used hospital administrative systems via the network. Over the past four years, our efforts have cost the equivalent of $23 million or approximately 0.5% of the total medical center budget. Even small improvements in productivity and in the quality of work of individuals who use the system could justify these expenditures. The challenges we still face include the provision of additional easy-to-use applications and development of equitable methods for financial support. 相似文献

In the present study, primary school children’s ability to give accurate confidence judgments (CJ) was addressed, with a special
focus on uncertainty monitoring. In order to investigate the effects of memory retrieval processes on monitoring judgments,
item difficulty in a vocabulary learning task (Japanese symbols) was manipulated. Moreover, as a first exploratory step to
uncover fast and retrieval bound (implicit) monitoring processes that take place before explicit CJ are openly reported, fixation
time allocation during recognition and monitoring was recorded with an eye-tracking device. Results revealed developmental
progression in uncertainty (but not in certainty) monitoring between the age of 7 and 9 years. Differences in CJ across levels
of item difficulty point to a substantial impact of retrieval processes on 9-yr-olds’ but not on 7-yr-olds’ monitoring. Eye-tracking
data revealed an overall bias towards medium and high CJ, and confirmed evidence on developmental progression in monitoring
skills. 相似文献

ABSTRACT WelServe is the database management system Welch Medical Library developed for quantitative assessment of services. The informationist team uses WelServe to capture data about direct service contacts with members of the research, clinical, and academic units at the Johns Hopkins Medical Institutions. WelServe data is used for library management and for reporting productivity data to higher units, including the Welch Advisory Committees, composed of deans and managers from the hospital and the schools of nursing, public health, and medicine. WelServe also supports reporting for the American Association of Health Sciences Libraries and the Association for Research Libraries. 相似文献

How do clinical questions emerge and move toward resolution in the intensive care setting over the course of 24 hours? In a 20-bed surgical intensive care unit in a large, tertiary-care teaching hospital, informationists shadowed clinicians for 2 48-hour periods to record questions, noting when they were asked and whether they were answered. Thirty-eight percent of 112 recorded questions remained unanswered. Some unanswered questions persisted across shifts, and clinicians'' information-seeking behaviors changed over time. Clinical information services can be improved and integrated more fully into clinical workflows based on a fuller understanding of the life cycle of clinical inquiry. 相似文献

Preparing librarians to meet the information challenges faced in the current and future health care environments is critical. At Johns Hopkins University, three NLM-funded fellowship programs provide opportunities for librarians to utilize the rich environments of the Welch Medical Library and the Division of Health Sciences Informatics in support of life-long learning. 相似文献

The Cushing/Whitney Medical Library began providing end-user access to MEDLINE in 1986 and switched to the OVID system in 1993. MEDLINE is a core service of the library, and the choice of delivery systems has had a significant impact throughout the Yale-New Haven Medical Center. This paper describes the user response to MEDLINE, discusses the effects of MEDLINE on other library services, and suggests ways in which technology, policy, and funding have influenced use. Yale's experience suggests that removing barriers in all three areas can dramatically expand the points of access, the number of users, and the amount of use with manageable effects on other library services. 相似文献

OBJECTIVE: The article offers a current perspective on medical informatics and health sciences librarianship. NARRATIVE: The authors: (1) discuss how definitions of medical informatics have changed in relation to health sciences librarianship and the broader domain of information science; (2) compare the missions of health sciences librarianship and health sciences informatics, reviewing the characteristics of both disciplines; (3) propose a new definition of health sciences informatics; (4) consider the research agendas of both disciplines and the possibility that they have merged; and (5) conclude with some comments about actions and roles for health sciences librarians to flourish in the biomedical information environment of today and tomorrow. SUMMARY: Boundaries are disappearing between the sources and types of and uses for health information managed by informaticians and librarians. Definitions of the professional domains of each have been impacted by these changes in information. Evolving definitions reflect the increasingly overlapping research agendas of both disciplines. Professionals in these disciplines are increasingly functioning collaboratively as "boundary spanners," incorporating human factors that unite technology with health care delivery. 相似文献
