Using social science to inform the law of intestacy: the case of unmarried committed partners.

Laws of intestate succession determine how the estate of a person who dies without a will is distributed. Researchers have struggled with the question of how to infer the donative intent of persons who die intestate. Based on an empirical study of unmarried committed partners, we compare the usefulness of two methods of social research for informing intestacy law: will studies and interviews with living persons about their preferences for estate distribution. The results indicate that for some groups of unmarried committed partners, will studies may not adequately reflect the extent to which intestate decedents wish their partner to share in their estate. In addition, the results demonstrate a close correspondence between respondents' actual wills, when they had them, and their distributive preferences on hypothetical scenarios. These findings are discussed as they relate to an examination of which sources of social scientific evidence are most useful in informing the law of intestacy.

Spatiotemporal modelling and mapping of the bubonic plague epidemic in India.

BACKGROUND: This work studies the spatiotemporal evolution of bubonic plague in India during 1896-1906 using stochastic concepts and geographical information science techniques. In the past, most investigations focused on selected cities to conduct different kinds of studies, such as the ecology of rats. No detailed maps existed incorporating the space-time dependence structure and uncertainty sources of the epidemic system and providing a composite space-time picture of the disease propagation characteristics. RESULTS: Informative spatiotemporal maps were generated that represented mortality rates and geographical spread of the disease, and epidemic indicator plots were derived that offered meaningful characterizations of the spatiotemporal disease distribution. The bubonic plague in India exhibited strong seasonal and geographical features. During its entire duration, the plague continued to invade new geographical areas, while it followed a re-emergence pattern at many localities; its rate changed significantly during each year and the mortality distribution exhibited space-time heterogeneous patterns; prevalence usually occurred in the autumn and spring, whereas the plague stopped moving towards new locations during the summers. CONCLUSION: Modern stochastic modelling and geographical information science provide powerful means to study the spatiotemporal distribution of the bubonic plague epidemic under conditions of uncertainty and multi-sourced databases; to account for various forms of interdisciplinary knowledge; and to generate informative space-time maps of mortality rates and propagation patterns. To the best of our knowledge, this kind of plague maps and plots become available for the first time, thus providing novel perspectives concerning the distribution and space-time propagation of the deadly epidemic. Furthermore, systematic maps and indicator plots make possible the comparison of the spatial-temporal propagation patterns of different diseases.

Transforming the present--discovering the future: the University of Pittsburgh's NLM grant on education and training of health sciences librarians.

BACKGROUND: The University of Pittsburgh was awarded a grant by the National Library of Medicine to study the education and training needs of present and future medical librarians and health information specialists through a collaboration of the university's School of Information Sciences and Health Sciences Library System. Goals and objectives for the year-long project included (1) assessment of education and training needs of medical librarians, (2) development of a master of library science curriculum and an internship program that would prepare graduates to take leadership roles in medical librarianship or information management, (3) development of continuing education programs for medical librarians in different formats, and (4) development of targeted recruitment efforts to attract minority group members and individuals with undergraduate science majors. The importance of this project, present practice, and success factors for programs seeking excellence in the preparation of health sciences information professionals are reviewed. A needs assessment involving a national advisory panel and a follow-up study of individuals who have participated in previous specialized training programs in health sciences information, compared with a peer group of medical librarians who did not participate in such programs, is described. This paper presents the goals and objectives of the project, describes the methods used, and outlines a curriculum, continuing education initiatives, and recruitment activities.

Description of integrated competency examination: tools to assess the chiropractic curriculum effectiveness and students' competency levels.

Los Angeles College of Chiropractic (LACC) has developed a variety of methods to monitor the effectiveness of its competency based/problem-centered curriculum. The College introduced two Integrative Competency Examination courses (ICE I and ICE II) to assess the chiropractic program's effectiveness and students' competency levels. The ICE courses are pass/fail examinations that use a multistation, objective structured clinical examination (OSCE) format that involves standardized patients along with cognitive assessment of basic science information as methods of evaluation. ICE I requires students to perform psychomotor skills and interpret clinical data; ICE II requires students to perform at a higher level. They are directed to select, perform and interpret clinical data appropriately and correlate this data with relevant basic science information. Through these two levels of evaluation, the educational program, the individual courses and the competency level of each student are assessed. This paper describes the format, content and evaluation tools used in the ICE courses as well as the potential benefits of the courses.

Research governance: implications for health library and information professionals.

The Research Governance Framework for Health and Social Care published by the Department of Health in 2001 provides a model of best practice and a framework for research in the health and social care sector. This article reviews the Department of Health Research Governance Framework, discusses the implications of research governance for library and information professionals undertaking research in the health- and social-care sector and recommends strategies for best practice within the information profession relating to research governance. The scope of the Framework document that covers both clinical and non-clinical research is outlined. Any research involving, amongst other issues, patients, NHS staff and use or access to NHS premises may require ethics committee approval. Particular reference is made to the roles, responsibilities and professional conduct and the systems needed to support effective research practice. Issues such as these combine to encourage the development of a quality research culture which supports best practice. Questions arise regarding the training and experience of researchers, and access to the necessary information and support. The use of the Framework to guide research practice complements the quality issues within the evidence-based practice movement and supports the ongoing development of a quality research culture. Recommendations are given in relation to the document's five domains of ethics, science, information, health and safety and finance and intellectual property. Practical recommendations are offered for incorporating research governance into research practice in ways which conform to the Framework's standards and which are particularly relevant for research practitioners in information science. Concluding comments support the use of the Research Governance Framework as a model for best practice.

Development of methodologic tools for planning and managing library services. IV. Bibliography of studies selected for methods and data useful to biomedical libraries.

This selective bibliography is intended to serve as a guide to empirical studies reporting data and methods that can be used by medical librarians to assess their own efforts objectively and to improve the effectiveness and efficiency of services they offer. The decision rules that governed selection of items for the bibliography are specified in detail. A total of 178 items published between 1915 and mid-1968 met the selection criteria. The list of items is supplemented by a keyword index derived from titles. Half the items are journal articles; a third of these articles appeared in the Bulletin, and most of the remainder in thirteen other library and information science journals. Most of the non-journal items are technical reports issued by the organization that conducted or sponsored the work. The characteristics of this literature suggest that few medical libraries, unless they are part of a university system that includes the collection of a library or information science school, are likely to have quick access to the literature base needed to support a comprehensive program of self-evaluation studies and the continuing education of their own staff. Regional medical libraries might well undertake to ensure both ready access to, and awareness of, literature on the scientific aspects of librarianship.

Integrated case studies and medical decision making: a novel, computer-assisted bridge from the basic sciences to the clinics.

This article describes a novel course that was designed to bridge the gap between the basic science years and clinical experiences in medical school by using information science and computer technology as major components of problem-based learning (PBL) sessions. The course, Integrated Case Studies and Medical Decision Making, was first given to second-year students at the University of Pittsburgh School of Medicine in the spring of 1994. It consists of 13 PBL exercises, each of which explores a clinical case. The cases, including images and gated access to information, are housed on a computer. Using one of 16 networked terminals in specially designed small-group rooms, groups of nine students progress through the cases with a faculty facilitator. The responses of students and faculty to the initial year of the course were favorable. In comparison with traditional PBL sessions, enhanced quality of and access to images and accountability for accessing case information in sequential fashion were cited as major strengths of the course. Juxtaposition of basic science and clinical material and utility in reviewing for the United States Medical Licensing Examination were also cited as strengths. The diversity of the basic science material involved in completing the cases drew overwhelming enthusiasm from students and facilitators alike. In conclusion, the course successfully employs computer and information science technology, which will be of increasing importance to future physicians. The course also serves as an effective bridge to the clinical years of medical school and as a study adjunct for the USMLE.

Generation of nonclassical photon pairs for scalable quantum communication with atomic ensembles.

Quantum information science attempts to exploit capabilities from the quantum realm to accomplish tasks that are otherwise impossible in the classical domain. Although sufficient conditions have been formulated for the physical resources required to achieve quantum computation and communication, there is a growing understanding of the power of quantum measurement combined with the conditional evolution of quantum states for accomplishing diverse tasks in quantum information science. For example, a protocol has recently been developed for the realization of scalable long-distance quantum communication and the distribution of entanglement over quantum networks. Here we report the first enabling step in the realization of this protocol, namely the observation of quantum correlations for photon pairs generated in the collective emission from an atomic ensemble. The nonclassical character of the fields is demonstrated by the violation of an inequality involving their normalized correlation functions. Compared to previous investigations of non-classical correlations for photon pairs produced in atomic cascades and in parametric down-conversion, our experiment is distinct in that the correlated photons are separated by a programmable time interval (of about 400 nanoseconds in our initial experiments).

Houseofficers' reactions to media coverage about the sequencing of the human genome.

After the announcement that sequencing of the human genome was nearly complete, media coverage was extensive. In light of ample evidence that the media are a primary source of health and science information, even for health professionals, media portrayals are often inaccurate or misleading, and discoveries that emanate from sequencing the human genome are likely to influence future health care, it is important to assess physicians' interpretations of media coverage about the human genome announcement. This paper describes the reactions of a sample of new physicians in the United States to this announcement, as well as the content of the stories they read or heard. Semi-structured surveys were distributed to all incoming houseofficers during Orientation at one major academic medical center. Eighty-one percent of 190 houseofficers returned a survey; 123 completed surveys were analyzed. Fifty-four percent of respondents thought the media message was only positive and 21% thought it was negative or mixed. Participants who reported radio as their media source were less likely to recall positive messages (p<0.05). Sixty-five percent and 76%, respectively, had positive perceptions of the impact of the accomplishment on people and on the medical profession. Overall, 48% were enthusiastic and 52% were guarded about the accomplishment. Enthusiasm was related to being an adult primary care houseofficer (p=0.07) or to having heard about it on television or in the newspaper (p<0.05). Of the 36 stories analyzed, newspaper and television reports focused more on medical implications and radio reports focused more on ethical issues. The degree of enthusiasm about the accomplishment reflects the content of the media coverage, and, at least for adult primary care houseofficers, probably reflects the increasing relevance of genetic discoveries to medical practice. Since physicians obtain much of their health and science information from the media, they can play an instrumental role in helping their patients interpret media coverage of advances in genetics and their impact on health care. However, this will require that physicians develop an appreciation of the newsmaking process, and how subtle interactions between politics, the media and science influence the "framing" of media coverage.

Stimulated emission of polarization-entangled photons.

Entangled photon pairs-discrete light quanta that exhibit non-classical correlations-play a crucial role in quantum information science (for example, in demonstrations of quantum non-locality, quantum teleportation and quantum cryptography). At the macroscopic optical-field level non-classical correlations can also be important, as in the case of squeezed light, entangled light beams and teleportation of continuous quantum variables. Here we use stimulated parametric down-conversion to study entangled states of light that bridge the gap between discrete and macroscopic optical quantum correlations. We demonstrate experimentally the onset of laser-like action for entangled photons, through the creation and amplification of the spin-1/2 and spin-1 singlet states consisting of two and four photons, respectively. This entanglement structure holds great promise in quantum information science where there is a strong demand for entangled states of increasing complexity.

Information and the unfolding of social life: molecular-biological resonances reaching up to the economy.

The much vexed analogy between cells, organisms, and societies receives a new treatment here. It is argued that, based on an enlarged view on the relationship between information and life, one can approach economy from an unusual angle: the accounting processes that take place in every productive unit and commercial organization. Such accounting processes have been historically developed in order to coordinate the economic 'physiology' of complex societies. In this sense, the convergence which can be found amongst the abstract, coordinating operations performed by cellular signaling systems, vertebrate nervous systems, and entrepreneurial accounting systems appears as a relevant theoretical item to analyze (the abstract organization of what can be called information 'phase transitions'). Its development lends support to the cogency of a 'vertical' information science approach.

The Missouri planning grant for the education and training of health sciences librarians.

The planning grant at the School of Library and Informational Science (SLIS) at the University of Missouri has two aims: (a) developing a model curriculum for health sciences librarianship at the master's level and (b) developing materials that can be delivered by alternative instructional methods. To accomplish the first aim, the faculty will investigate the possibility of offering courses in other disciplines, such as health care administration, educational technology, adult education, and medical sociology. In addition, the SLIS faculty will investigate the development of new kinds of placement for the students' practicum experience. To reach the second aim, the SLIS faculty will investigate alternative means of delivering both graduate and continuing education. Three instructional modalities will be evaluated. Some material will be delivered via satellite broadcast, some material will be made available via the World Wide Web and some will be presented in an intensive seminar. The outcome of the planning grant will be two distinct plans. The first will be a plan for the curriculum in health sciences librarianship at the master's level. The second will be a plan for offering instruction through alternative methods, both for graduate education and for continuing education.

Communicating with children and adolescents about their cancer.

BACKGROUND: Communication with children and adolescents with cancer about their disease and treatment and the implications of these is an important aspect of good quality care. It is often poorly performed in practice. Various interventions have been developed that aim to enhance communication involving children or adolescents with cancer. OBJECTIVES: To examine the effects of interventions to enhance communication with children and/or adolescents about their cancer, its treatment and their implications. SEARCH STRATEGY: The following electronic databases were searched: Cochrane Library; Medline; PsycLit; Cinahl; Cancerlit; EMBASE; Sociofile; Health Management Information Consortium; ASSIA; LISA; ERIC; PAIS; Information Science Abstracts; Dissertation Abstracts; JICST; Pascal; Linguistics and Language Behavior Abstracts; Mental Health Abstracts; AMED; MANTIS. Bibliographies of identified studies were also checked and contact made with experts in the field. SELECTION CRITERIA: Randomised and non-randomised controlled trials and before and after studies that evaluated the effects of interventions to enhance communication with children and/or adolescents about their cancer, treatment and related issues. DATA COLLECTION AND ANALYSIS: Data relating to the interventions, populations and outcomes studied and the design and methodological quality of included studies were extracted by one reviewer and checked by another reviewer. A narrative summary of the results is presented. MAIN RESULTS: Six studies met the criteria for inclusion. They were diverse in terms of the interventions evaluated, study designs used, types of people who participated and the outcomes measured. One study of a computer-assisted education programme reported improvements in knowledge and understanding about blood counts and cancer symptoms. Two out of two studies of school reintegration programs reported improvements in some aspects of psychosocial wellbeing (one in anxiety and one in depression), social wellbeing (two in social competence and one in social support) and behavioural problems; and one reported improvements in physical competence. REVIEWER'S CONCLUSIONS: Interventions to enhance communication involving children and adolescents with cancer have not been widely or rigorously assessed. The weak evidence that exists suggests that some children and adolescents with cancer may derive some benefit from specific information-giving programs and from interventions that aim to facilitate their reintegration into school and social activities. More research is needed to investigate the effects of these and other related interventions.

An evidence-based approach to interactive health communication: a challenge to medicine in the information age. Science Panel on Interactive Communication and Health.

OBJECTIVE: To examine the current status of interactive health communication (IHC) and propose evidence-based approaches to improve the quality of such applications. PARTICIPANTS: The Science Panel on Interactive Communication and Health, a 14-member, nonfederal panel with expertise in clinical medicine and nursing, public health, media and instructional design, health systems engineering, decision sciences, computer and communication technologies, and health communication, convened by the Office of Disease Prevention and Health Promotion, US Department of Health and Human Services. EVIDENCE: Published studies, online resources, expert panel opinions, and opinions from outside experts in fields related to IHC. CONSENSUS PROCESS: The panel met 9 times during more than 2 years. Government agencies and private-sector experts provided review and feedback on the panel's work. CONCLUSIONS: Interactive health communication applications have great potential to improve health, but they may also cause harm. To date, few applications have been adequately evaluated. Physicians and other health professionals should promote and participate in an evidence-based approach to the development and diffusion of IHC applications and endorse efforts to rigorously evaluate the safety, quality, and utility of these resources. A standardized reporting template is proposed to help developers and evaluators of IHC applications conduct evaluations and disclose their results and to help clinicians, purchasers, and consumers judge the quality of IHC applications.
