The anterior cruciate ligament.

Our knowledge of the anterior cruciate ligament has expanded rapidly over the last decade. Recent advances in arthroscopic techniques, the development and release of synthetic stents and prostheses, increasing laboratory and clinical data involving allograft implantation, and biomechanical research in knee rehabilitation have led to a bewildering array of choices for treatment of anterior cruciate ligament deficiency. As new information and techniques are presented, and new synthetic and biological materials become available, orthopedic surgeons must judge their value and modify treatment recommendations accordingly. A thorough knowledge of the basic science and clinical information is necessary to appropriately evaluate these new advances. A review of our current knowledge of the anterior cruciate ligament is presented to facilitate this evaluation process.

[Status of NIHS Computer Network System (NIHS-NET)].

We described the development of National Institute of Health Sciences Computer Network System (NIHS-NET), which was named NIHS Information and Computing Infrastructure (NICI) previously. In the system, the main server machines and common machines were replaced and the network lines were upgraded from 100 Mbps to 1Gbps. The connection nodes were changed from Inter Ministry Network (IMnet) to Science Information Network (SINET), and the dedicated lines between NIHS (yoga, osaka, tsukuba) and SINET were constructed. The Internet connection speed from each campus to SINET was upgraded. We also performed security audit in this system.

Feasibility and marketing studies of health sciences librarianship education programs.

The University of North Carolina at Chapel Hill evaluated five curricular models designed to improve education for health sciences librarianship. Three of the models enhanced existing degree and certificate programs, and two were new programs for working information professionals. Models were developed with input from experts and a Delphi study; the marketability of the models was tested through surveys of potential students and employers; and recommendations were made as a guide to implementation. The results demonstrated a demand for more specialized curricula and for retraining opportunities. Marketing data showed a strong interest from potential students in a specialized master's degree, and mid-career professionals indicated an interest in postmaster's programs that provided the ability to maintain employment. The study pointed to the opportunity for a center of excellence in health sciences information education to enable health sciences librarians to respond to their evolving roles.

Developmental psychobiology and response to threats: relevance to trauma in children and adolescents.

Interest in developmental and psychobiological aspects of trauma has grown with recent research in adults with mood and anxiety disorders reporting histories of trauma during childhood. Studies conducted directly in children and adolescents could add much to ongoing research in this area. This review summarizes data in three areas of developmental science that might inform future studies. First, the review briefly summarizes current data on clinical aspects of trauma in juveniles, focusing on associations with psychopathology and moderators of outcome. Second, the review summarizes data from the basic sciences delineating experiential and developmental changes in brain systems involved in threat perception and response. This review incorporates knowledge gained from research examining the effects of rearing manipulations on regulation of the stress response in rodents and primates. Third, the review summarizes data from cognitive neuroscience studies among both adults and children, again focusing on studies examining aspects of the threat response. This summary includes a review from studies in patients with posttraumatic stress disorder.

Procedural misconceptions and informed consent: insights from empirical research on the clinical trials industry.

This paper provides a simultaneously reflexive and analytical framework to think about obstacles to truly informed consent in social science and biomedical research. To do so, it argues that informed consent often goes awry due to procedural misconceptions built into the research context. The concept of procedural misconception is introduced to describe how individuals respond to what is familiar in research settings and overlook what is different. In the context of biomedical research, procedural misconceptions can be seen to function as root causes of therapeutic misconceptions.

Cluster analysis of structural stage classes to map wildland fuels in a Madrean ecosystem.

Geospatial information technology is changing the nature of fire mapping science and management. Geographic information systems (GIS) and global positioning system technology coupled with remotely sensed data provide powerful tools for mapping, assessing, and understanding the complex spatial phenomena of wildland fuels and fire hazard. The effectiveness of these technologies for fire management still depends on good baseline fuels data since techniques have yet to be developed to directly interrogate understory fuels with remotely sensed data. We couple field data collections with GIS, remote sensing, and hierarchical clustering to characterize and map the variability of wildland fuels within and across vegetation types. One hundred fifty six fuel plots were sampled in eight vegetation types ranging in elevation from 1150 to 2600 m surrounding a Madrean 'sky island' mountain range in the southwestern US. Fuel plots within individual vegetation types were divided into classes representing various stages of structural development with unique fuel load characteristics using a hierarchical clustering method. Two Landsat satellite images were then classified into vegetation/fuel classes using a hybrid unsupervised/supervised approach. A back-classification accuracy assessment, which uses the same pixels to test as used to train the classifier, produced an overall Kappa of 50% for the vegetation/fuels map. The map with fuel classes within vegetation type collapsed into single classes was verified with an independent dataset, yielding an overall Kappa of 80%.

UMIN--current status and future perspectives.

UMIN, fully funded by the Japanese government, is the largest and most versatile public academic information center for biomedical sciences in the world, and is considered as indispensable information infrastructure for the Japanese medical community. As of April 1st 2004, all Japanese national universities, including UMIN, will be incorporated as independent administrative entities. After the incorporation, each national university will have authority to determine its own budget, organization, etc. by itself, and will also be able to carry out profit-making business related to its activities under certain constraints. Thus we suspect that UMIN will inevitably be faced with a strong demand to undertake profit-making business at an early stage. Even in this case, we believe that UMIN should continue to provide its information services to the Japanese medical community free of charge as it has done, utilizing earnings from its profit-making business that services commercial companies, because the success of UMIN has depended on the cooperation and sympathy of the community in the past, and will continue to do so.

The information behaviors of life and health scientists and health care providers: characteristics of the research literature.

BACKGROUND: In a literature-based discussion of research on the information behaviors of life and health scientists and health care practitioners, the problem of characterizing this complex literature is discussed. The issue of terminology for this interdisciplinary area is raised. The paucity of models for information seeking behavior that have been tested in a health care population is discussed, as are the frequently used methods of investigation and data collection methods. METHODS: By analyzing a large number of information behavior research studies, the questions of who does the research and where the research is published are answered. The characteristics of this research are discussed. Studies are cited that investigate the information behavior of physicians, multidisplinary groups of health professionals, medical students and faculty, nurses and other allied health personnel, life scientists, and basic science researchers. Two short case studies--on the diffusion of medical knowledge and on drug information and physician behavior--are used as examples of information behavior research. CONCLUSIONS: The importance of studying the information behavior of health and life scientists and health care providers is underscored by a discussion of the implications for further study.

Informing juvenile justice policy: directions for behavioral science research.

Recent policy initiatives threaten to reduce the rehabilitative mission of the juvenile court or eliminate the court entirely. This article lays out a framework for an empirical assessment of these developments. It first evaluates the available and potential empirical support for three hypotheses about juveniles that might justify maintaining a separate, rehabilitation-oriented juvenile justice system: the hypotheses that, compared to adults, juveniles are more treatable, less culpable, and less deterrable. On the assumption that the continued existence of a rehabilitation-oriented juvenile court can be justified, it then provides suggestions as to how existing intervention strategies for juveniles could benefit from research attention to several substantive and methodological issues. These include refining outcome criteria and sampling strategies, matching offender and program characteristics, reexamining intervention efficacy, and focusing on decision makers and resource allocations.

Special programs in medical library education, 1957-1971. II. Analysis of the programs.

In this report, responses to a questionnaire to the directors of the sixteen past and present medical library education programs are presented. The questionnaires indicate a rather wide variety of training programs with emphases that vary from preparation of management personnel to preparation of subject specialists and those skilled in the techniques of information storage and retrieval. The content of the degree programs is fairly evenly divided among general retrieval and outside courses. The internship programs place more emphasis on the work experience than do the degree programs, supplementing this experience with appropriate courses in science, health sciences, management, and information storage and retrieval. Program directors indicated that new or expanded programs are needed in medical library education, although caution is reflected in comments concerning the limited job market. Most of the internship directors stated that they could not accommodate more individuals in their programs without expansion of staff and facilities.

Communicating original research in chemistry and related sciences.

The availability of scientific information in electronic form is the convergence of traditional journal publishing, electronic communications, and the widespread availability of computer technology. This revolution in scientific communication has its roots in developments that started in the mid-19th century and culminated with the extraordinary progress in telecommunications and computer technology in the latter years of the 20th century. Eighty-three percent of scientific journals are now available online. The benefits of electronic journals include rapid publication, instantaneous linking to external information sources, and the capability to deliver new types of information. To date neither electronic-only nor preprint servers have been well received by the chemical sciences community. Continued advances in telecommunications, computer technology, and acquisition of scientific data in structured formats hold promise for even greater advances in communication of scientific information.

Vocal fold wound healing: a review for clinicians.

SUMMARY: The basic science of wound healing is largely omitted from the curriculum of many voice clinicians. This fact is relatively disheartening as most therapeutic manipulation in the realm of laryngology and voice disorders deals with injured tissue. Therefore, the selection of therapeutic tasks for persons with vocal injury should ideally be informed by basic science in wound healing. Recently, several investigators have initiated lines of research to determine the course of vocal fold wound healing and the potential role of therapeutic agents, including behavioral agents. The current review seeks to provide a foundation of basic wound healing science and present the most current data regarding the wound healing process in the vocal folds.

Scientific information and uncertainty: challenges for the use of science in policymaking.

Science can reinforce the healthy aspects of the politics of the policy process, to identify and further the public interest by discrediting policy options serving only special interests and helping to select among "science-confident" and "hedging" options. To do so, scientists must learn how to manage and communicate the degree of uncertainty in scientific understanding and prediction, lest uncertainty be manipulated to discredit science or to justify inaction. For natural resource and environmental policy, the institutional interests of government agencies, as well as private interests, pose challenges of suppression, over-simplification, or distortion of scientific information. Scientists can combat these maneuvers, but must also look inward to ensure that their own special interests do not undermine the usefulness of science.

Process and detection in fraud and deceit.

There has been considerable interest recently in scientific misconduct. Although much has been written and discussed about specific cases, very little, if any, research has been carried out on the process of fraud. An understanding of this aspect can contribute much to methods of detection and lead to recommendations for preventing misconduct and for implementation of appropriate sanctions where fraud has been detected and proved. In this article I initiate a study of the process of fraud using a series of case studies. Hypotheses are generated by methods pioneered by Peirce and most recently developed and thoroughly discussed by Glaser and Strauss under the name of grounded theory. Some illustrations of what can be learned from such studies are included.
