OBJECTIVE: Two branches of applied social science have devoted substantial attention to researching information seeking and use. One branch is the field of communication, with its emphasis on the design of messages to effectively transmit expert information. The second is the field of library and information science, with its emphasis on meeting user needs. This paper is an overview and comparison of what is known about information seeking and use based on these two bodies of research, particularly as it applies to serving the needs of racial and ethnic minorities. DATA SOURCE: This paper is informed by three in-depth literature reviews of the two fields and of the difficulties of bringing findings from disparate fields to bear on the same phenomena. CONCLUSIONS: Twenty-five broad brushstroke propositions are extracted in a way that allows both commonalities and contradictions to be informative, particularly as they relate to how the flexibilities offered by electronic technologies may allow experts to serve user needs more effectively and efficiently. Remarkably, while both fields have approached their studies from separate viewpoints without much overlap, both have struggled with the baggage imposed on their research by information-as-transmission assumptions and both have moved toward approaches that focus on information-as-communication.
This paper argues a number of points about measurement in the sociology of mental health: (1) measurement is critical, (2) measures should represent and assess elements of human experience, taking measure of life as people feel it, sense it, and understand it, and (3) social scientists should create a human science, producing information for the people it studies so that they can better understand and control their own lives. We argue that a human science is best achieved with the use of indexes, not diagnoses, to measure mental health. We present a brief history of diagnostic instruments and detail how a diagnosis is made. We show how use of diagnoses to measure mental health discounts much human suffering. They dichotomize the true range of feelings and emotions into crude either/or distinctions that do not reflect the reality of people's lives, and they often exclude suffering such as that due to loss or illness that does not meet medical model preconceptions about mental disorder. Using diagnoses to measure mental health presents a reified image of hidden disease knowable and manageable only by trained professionals--beyond the capacity of the suffering individuals to understand and control.
The need for nurses with expertise in technology and information systems is expected to increase. This article describes a collaboration between a university's school of nursing and school of computer science and information to prepare nurses who wish to become nurse informaticians. The specifics of the master's-level Collaborative Nursing Informatics Program are discussed, classroom and clinical experiences are described, and evaluation processes are summarized.
Patient-care-assessment systems have failed to demonstrate efficiency in detecting continuing education needs or in influencing clinical practice. We believe that one of the weaknesses in retrospective audit systems is their tendency to result in the ratification of criteria which match past practices rather than criteria which incorporate new, science-based information. This is in spite of the fact that for many years guidelines for medical audit processes have encouraged physicians to develop science-based criteria. This study was undertaken to determine whether continuing education programs preceding patient care audits can induce physicians to choose criteria beyond their own experience. A highly significant difference was found between audit criteria developed after education programs and those which were developed without such programs. The results indicate that educational efforts can have a striking effect on the criteria ratified by audit committees.
The need to develop skills in Information Technology and Information Literacy for a career in the Health Sciences is not in dispute. More debated are the most appropriate ways of assessing existing skills, addressing training needs and incorporating IT/IL learning, and at what stage skills development should begin to be most effective. This article reports on three years of experience with a training model in the Faculty of Health Sciences, University of Cape Town, in providing IT/IL skills to a diverse group of students in South Africa. It provides an evaluation of the activities and discusses the possible advantages of the methodology. This training model is based on measuring rather than assuming existing computer skills in incoming students; it is informed by curriculum demands and focuses on early intervention and close integration into mainstream undergraduate courses.
Modern pork production uses a variety of tools to ensure the health, welfare and productivity of pigs. Therapeutic (treatment and prevention of disease) use and use for enhancing growth and feed efficiency (growth promotion) are the two options for use on the farm. Collecting meaningful and accurate antibiotic use data faces significant challenge because of the number and variety of production systems, the need for broad stakeholder analysis of the data and the lack of consistent and science-based definitions of antibiotic use categories. The National Animal Health Monitoring System (NAHMS) is one mechanism that estimates uses based on a statistical sample of the nation's swine herd. If, based on sound science, additional information on antibiotic use is considered necessary, stakeholders should discuss the best implementation strategies to achieve the desired result. Producers continue in their science-based commitment to ensure the safety of pork and to maintain consumer confidence.

The precautionary principle implies the need for research paradigms that contribute to "strength of the evidence" assessments of the plausibility of health effects when scientific uncertainty is likely to persist and prevention is the underlying goal. Previous discussions of science that inform precautionary decision making are augmented by examining three activist-initiated breast cancer and environment studies--the Long Island, New York, and Cape Cod, Massachusetts, studies and the National Institute of Environmental Health Sciences breast cancer and environment centers. These studies show how the choice of research questions affects the potential of results to inform action. They illustrate a spectrum of public involvement, population- and individual-level epidemiologic study designs, and the crucial importance of developing and applying new exposure assessment methods. The exposure studies are key because they are critical in assessing plausibility (without exposure to a causal agent, there is no health effect), are prerequisite to health studies, and identify preventable exposures that could be reduced by precautionary policies, even in the absence of strong evidence of harm. The breast cancer studies have contributed to environmental and biological sampling programs for endocrine-disrupting compounds in drinking water and household air and dust and the application of geographic information systems for surveillance and historical exposure assessment. They leave unanswered questions about when to invest in large epidemiologic studies, when negative results are sufficient, and how to pursue ambiguous positive results in further research and policy.
Successful integrated information systems implementation requires an effective marriage of technology and information resources in response to critical institutional needs. The University of Washington technical infrastructure, developed over the past five years, includes ubiquitous, high-speed network access throughout the Health Sciences Center and hospitals, agreement on network standards and protocols, uniform interface to common databases (character-based and GUI) and network availability of a variety of databases and information resources at no charge to the individual. As a result of this heavy institutional investment in technical infrastructure, our implementation process will focus on expanding the number of available resources as well as developing and refining tools and services to enhance the utility of electronic information resources. Above all we will study and develop strategies for dealing with the myriad of information policy issues which confront and confound us all today.
In response to inquiries that reached the group of information at the Institute of Nutrition of the AMS of the USSR sources of information for terminology in the science of nutrition were educed. The paper brings forward the results of this work, viz. information on manuals, terminological and parallel glossaries, standards and other publications carrying information on terminology in the said and related sciences. The paper covers sources published during the past 15 years in Russian, English, German and French.
OBJECTIVE: To describe the steps taken by the Hawaii Society for Clinical Laboratory Science, an affiliate of the American Society for Clinical Laboratory Science, to inform local laboratory professionals of current trends and to prepare for the future. RESULTS: A Strategic Planning workshop was conducted at the 1997 Hawaii Society for Clinical Laboratory Science Annual Meeting where participants reviewed the essential (but non-traditional) functions of clinical laboratory scientists, and described current realities, identified forces and players affecting the changes, and envisioned the future of our profession. CONCLUSION: As the way health care is provided changes in response to economics and advances in technology, the role of clinical laboratory scientists needs to be redefined. The Hawaii Society for Clinical Laboratory Science continues to provide timely support for members, and plans to work collaboratively with the local chapter of the Clinical Laboratory Managers' Association to advance clinical laboratory science to an appropriate place in the health care community.
An organizational framework for integrating foodservice data into an information system for management decision making is presented. The framework involves the application to foodservice of principles developed by the disciplines of managerial economics and accounting, mathematics, computer science, and information systems. The first step is to conceptualize a foodservice system from an input-output perspective, in which inputs are units of resources available to managers and outputs are servings of menu items. Next, methods of full cost accounting, from the management accounting literature, are suggested as a mechanism for developing and assigning costs of using resources within a foodservice operation. Then matrix multiplication is used to illustrate types of information that matrix data structures could make available for management planning and control when combined with a conversational mode of computer programming.
In this study, the authors review the records of 63 graduates of Northwestern University Medical School who were residents in its graduate medical education programs of anesthesia and orthopedic surgery. They examine the relationship among college grades, medical school performance, and the results of assessment by annual, nationwide, medical specialty in-training examinations. For the anesthesia group, the best predictors of in-training examination performance were the Medical College Admission Test (MCAT) Verbal Ability score, the college grade-point average for nonscience subjects, and the MCAT Science, General Information, and Quantitative Ability scores. For the orthopedic group, the best predictors were the MCAT Verbal Ability score, the college grade-point average in nonscience subjects, the MCAT Science score, and the National Board of Medical Examiners Part I and Part II examination scores. The previous academic records for the 63 residents contained little to presage results in the in-training examination. The correlation obtained between nonscience college subjects and the in-training examination results was negative.

Users of information in science and technology have been studied in great detail with respect to material read, amount of time spent in reading and searching the literature, categories of questions asked, and so on. Probing for this information has been undertaken by means of structured and unstructured interviews, diaries, surveys, and questionnaires.Although a large amount of data has emerged on information usage and flow, the subjective response of scientists furnishes comment only on the satisfaction produced by present information services and does not yield insight into the extent to which needs remain unsatisfied. Relevance figures based upon the response of systems to questions cannot be equated with satisfaction of needs, since questions constitute, in most cases, inadequate representations of underlying information needs. Assessment of the needs of users of medical libraries and information systems must, in fact, be made in relation to the observed behavior and experience of biomedical scientists. There is room for well-designed experimentation which can explore the interaction of both psychological and environmental factors. Significant differences in information needs exist among and between individuals such as researchers and clinicians in the same environment. With respect to environment, it is hypothesized that the information needs of medical practitioners in remote areas might differ significantly from those of their colleagues working in large metropolitan centers in close proximity to medical schools, research institutions, and other rich sources of information fallout. It is anticipated that experimentation will eventually result in a methodology which will permit the determination and prediction of the information needs of any identified groups of users in a specific environment.
We all take risks, but most of the time we do not notice them. We are generally bad at judging the risks we take, and in the end, for some of us, this will prove fatal. Eating, like everything else in life, is not risk free. Is that next mouthful pure pleasure, or will it give you food poisoning? Will it clog your arteries as well as filling your stomach? This lecture weaves together three strands-the public understanding of science, the perception of risk and the role of science in informing government policy-as it explains how food risks are assessed and managed by government and explores the boundaries between the responsibilities of the individual and the regulator. In doing so, it draws upon the science of risk assessment as well as our attitudes to risk in relation to issues such as bovine spongiform encephalopathy, dioxins in salmon and diet and obesity.
