A service-oriented information sources database for the biological sciences.

Researchers in the biological sciences require access to a variety of information sources located in various places on different computer networks. In order to satisfy the information needs of a researcher, appropriate information sources must be selected and access to these information sources and the computing services supporting them must be provided in a way that does not distract the researcher from problems of real interest. At the University of Missouri-Columbia a service-oriented information sources database is being developed as a key component of a layered-model design of an intelligent system which will provide a research environment appropriate to the needs of researchers in the biological sciences.

Physical therapists in private practice: information sources and information needs.

Increasing numbers of physical therapists are providing evaluation and therapy in their own private-practice clinics. Their move out of the hospital setting has reduced their access to the sources of information designed to support clinical and practice-management decision making. The author designed a survey to determine how often physical therapists in private practice in Vermont use seven sources of information for clinical and practice-management decision making. Survey respondents also were asked to rate the anticipated usefulness of a variety of health sciences library information and research services not currently available to them and to rank access paths to information according to their preferences. The therapists' responses show frequent reliance on personal and office collections of professional literature for clinical decision making but virtually no use of bibliographic databases. Respondents ranked document-delivery services and mediated searches as having the greatest anticipated usefulness for clinical decision making. The limitations of their current information-seeking behavior and their high level of interest in increased access to a wide range of information and research services make physical therapists in private practice of special interest to health sciences librarians who are planning outreach programs.

IT services in a completely digitized radiological department: value and benefit of an in-house departmental IT group.

To analyze the benefit of a departmental IT group in comparison to support by hospital IT groups or system manufacturers in a completely digitized radiological department. The departmental IT group comprises a fulltime IT specialist, two student assistants and four clinical employees participating 1 day/week. For 18 months IT problems were quantified and specified according to urgency, responsibility and affected system by use of an intranet-based reporting system. For each IT service provider the performance and duration of problem solution was evaluated. In 18 months 3,234 IT problems emerged. 88.7% were solved by the departmental IT group. In 474 cases (14.7%) a solution within 2 h was required. The departmental IT group solved 35.8% within 30 min, system manufacturers needed 18 h 38 min in mean. The departmental IT group solved 90.2% of the problems within a time limit. System manufacturers met the limit in 60.1% with a mean duration of 7 days 21 h. In 6.7% of the cases, support by system manufacturers was indispensable. A considerable proportion of IT problems in completely digitized radiological departments can be solved by a departmental IT group, providing a fast and cost-efficient first-level IT support with effective prevention of major breaks in the workflow. In a small number of cases support by system manufacturers remains necessary.

University entry scores as a predictor of academic performance in a health information management program.

The university entry scores for school leavers admitted to the first year of the Bachelor of Applied Science (Health Information Management) degree at the University of Sydney in 1996 were examined to determine whether the Tertiary Entrance Rank (TER) was a good predictor of academic performance, as measured by grade point average (GPA). The study also examined Higher School Certificate (HSC) results in English and mathematics, and preference selection for the health information management (HIM) course to determine whether any of these had predictive validity. The results showed that TER, HSC English and mathematics scores and preference for the course were all poor predictors of academic performance in the student's first year. Low TER was not associated with low GPA and low scores in English and mathematics were not associated with low GPA. There was no significant difference between the performance of those students who listed the HIM course as their first preference and those who did not. These results suggest that there may be no need to establish a minimum entry level for admission to the HIM course, or for prerequisites in English and mathematics. It may be that multiple criteria are required to predict academic success in this course.

[An international exchange and dissemination of chemical safety information on the Internet].

An information system for chemical safety has been developed on the National Institute of Health Sciences (NIHS) Information and Computing Infrastructure. The system is based on client server systems on the local area network (LAN) connected to the Internet. A wide range of safety information for chemicals including foods, food additives, household goods, industrial chemicals and environmental pollutants were collected and put on the World Wide Web (WWW) server and the database management system, Sybase. In addition to original information contents, the System has links to many useful Web sites so that it functions as a global hub for chemical safety information.

A memory span of one? Object identification in 6.5-month-old infants.

Infants' abilities to identify objects based on their perceptual features develop gradually during the first year and possibly beyond. Earlier we reported [Káldy, Z., & Leslie, A. M. (2003). Identification of objects in 9-month-old infants: Integrating 'what' and 'where' information. Developmental Science, 6, 360-373] that infants at 9 months of age are able to use shape information to identify two objects and follow their spatiotemporal trajectories behind occlusion. On the other hand, another recent study suggests that infants at 4-5 months of age cannot identify objects by features and bind them to locations [Mareschal, D., & Johnson, M. H. (2003). The "what" and "where" of object representations in infancy. Cognition, 88, 259-276]. In the current study, we investigated the developmental steps between these two benchmark ages by testing 6.5-month-old infants. Experiment 1 and 2 adapted the paradigm used in our previous studies with 9-month-olds that involves two objects hidden sequentially behind separate occluders. This technique allows us to address object identification and to examine whether only one or both object identities are being tracked. Results of experiment 1 showed that 6.5-month-old infants could identify at least one of two objects based on shape and experiment 2 found that this ability holds for only one, the last object hidden. We propose that at this age, infants' working memory capacity is limited to one occluded object if there is a second intervening hiding. If their attention is distracted by an intervening object during the memory maintenance period, the memory of the first object identity appears to be lost. Results of experiment 3 supported this hypothesis with a simpler one-screen setup. Finally, results of experiment 4 show that temporal decay of the memory trace (without an intervening hiding) by itself cannot explain the observed pattern of results. Taken together, our findings suggest that at six months of age infants can store but a single object representation with bound shape information, most likely in the ventral stream. The memory span of one may be due to immaturity of the neural structures underlying working memory such that intervening items overwrite the existing storage.

Women's health and complexity science.

Conceptual frameworks in science have shifted from reductionism and its focus on ever-smaller parts to complexity, an outgrowth of chaos theory that views those parts in relation to one another, to the larger entity they form and to the environment in which that entity exists. Examples of this conceptual shift are occurring in many areas of science, but nowhere is it more germane than in the medical sciences that serve women. After a historical focus on reproduction and the development of obstetrics-gynecology, medicine has now gained a broader view of the woman using sex- and gender-based science, and a new field called "women's health" is evolving. Complexity science does not invalidate or eliminate the need for reductionist science, it simply makes a wider array of phenomena understandable. Its method allows going beyond the metaphor of the body as a machine and challenges the user to re-examine how health and illness are understood. This article explores how these changes in science must inform the development of an academic discipline in women's health. The conceptual framework of complexity science also advances the discussions about women's health from reproduction to a totally new and exciting exploration of the interactions between reproduction and all other organ functioning that occurs in women in the contexts of their lives.

Why scientists should cooperate with journalists.

Despite a widespread impression that the public is woefully ignorant of science and cares little for the subject, U.S. National Science Foundation (NSF) surveys show the majority are very interested and understand that they are not well informed about science. The data are consistent with the author's view that the popularity of pseudoscience does not indicate a rejection of science. If this is so, opportunities for scientists to communicate with the public promise a more rewarding result than is commonly believed among scientists. In fact, the increasing visibility of science in the mass media correlates with a slow, steady improvement in public understanding of science in recent years.

Grounding a new information technology implementation framework in behavioral science: a systematic analysis of the literature on IT use.

Many interventions to improve the success of information technology (IT) implementations are grounded in behavioral science, using theories, and models to identify conditions and determinants of successful use. However, each model in the IT literature has evolved to address specific theoretical problems of particular disciplinary concerns, and each model has been tested and has evolved using, in most cases, a more or less restricted set of IT implementation procedures. Functionally, this limits the perspective for taking into account the multiple factors at the individual, group, and organizational levels that influence use behavior. While a rich body of literature has emerged, employing prominent models such as the Technology Adoption Model, Social-Cognitive Theory, and Diffusion of Innovation Theory, the complexity of defining a suitable multi-level intervention has largely been overlooked. A gap exists between the implementation of IT and the integration of theories and models that can be utilized to develop multi-level approaches to identify factors that impede usage behavior. We present a novel framework that is intended to guide synthesis of more than one theoretical perspective for the purpose of planning multi-level interventions to enhance IT use. This integrative framework is adapted from PRECEDE/PROCEDE, a conceptual framework used by health planners in hundreds of published studies to direct interventions that account for the multiple determinants of behavior. Since we claim that the literature on IT use behavior does not now include a multi-level approach, we undertook a systematic literature analysis to confirm this assertion. Our framework facilitated organizing this literature synthesis and our analysis was aimed at determining if the IT implementation approaches in the published literature were characterized by an approach that considered at least two levels of IT usage determinants. We found that while 61% of studies mentioned or referred to theory, none considered two or more levels. In other words, although the researchers employ behavioral theory, they omit two fundamental propositions: (1) IT usage is influenced by multiple factors and (2) interventions must be multi-dimensional. Our literature synthesis may provide additional insight into the reason for high failure rates associated with underutilized systems, and underscores the need to move beyond the current dominant approach that employs a single model to guide IT implementation plans that aim to address factors associated with IT acceptance and subsequent positive use behavior.

A framework for evaluation of medical information systems.

The evaluation of information systems, especially in the health care field, is a complex task. While in the general information system science field there have been several attempts to build frameworks and models to understand better the evaluation of information systems, in health care such models have been non-existent. Unfortunately general frameworks cannot be exactly applied for the evaluation of medical information systems, because they do not recognise the specific nature of the medicine. This article represents an attempt at formulating conceptual models to understand the evaluation of the different impacts of medical information systems.
