The Potential of Virtual Reality for Police Training Under Stress: A SWOT Analysis
Full text linkTo prepare for critical incidents on duty, police officers need to acquire the skills and tactics in realistic environments so that they transfer to high-stress circumstances. To bridge the gap between empirical research and applied practice, the present chapter informs about training concepts within the ecological dynamics framework that effectively promotes performance under stress. Specifically, scenario-based police training is critically discussed by identifying research gaps and challenges in the current practice. Virtual reality (VR) is introduced as a promising tool to overcome these challenges in police training and research. The aim of the present chapter is to inform, update, and improve researchers', police trainers', and curriculum developers' knowledge of VR as a tool to address the need for representative stress training while acknowledging its strengths, weaknesses, opportunities, and threats
Causes of change in the health of populations: A biopsychosocial viewpoint
No full textIn the current review, a biopsychosocial perspective is applied to current changes in the health of populations. It is proposed that the psychosocial environments either promote health or precipitate disease. Changes in the types of stress that people experience as well as its prevalence over time are discussed. In addition, possible biological mechanisms linking the psychosocial environments to health are presented. "Food for thought" is the possible interaction between the physical/chemical and the psychosocial environments and changes in health of individuals. Clearly, our traditional view of disease mechanisms is not sufficient to understand recent phenomena, such as environmental illness and chronic fatigue syndrome. Issues worthy of further discussions are the role of the "just-in-time" society, where individuals increasingly have to change jobs, cope with reorganizations and increased production pressure, and its impact on health and well-being. Further, in what way can we develop better models to truly assess the impact of an increasingly complex interaction between individual and environmental factors on health? A major obstacle to enhancing our understanding of causes of change in the health of populations is the use of inappropriate or outdated statistical analytical models. Finally, it is suggested that prospectively controlled studies of the impact on health of changes in the health and welfare systems are carried out. This would further add to our understanding of factors contributing to changes in the health of population.public health modern society complex causes
Psychosocial challenges facing physicians of today
No full textFundamental changes in the organization, financing, and delivery of health care have added new stressors or opportunities to the medical profession. These new potential stressors are in addition to previously recognized external and internal ones. The work environment of physicians poses both psychosocial, ergonomic, and physico-chemical threats. The psychosocial work environment has, if anything, worsened. Demands at work increase at the same time as influence over one's work and intellectual stimulation from work decrease. In addition, violence and the threat of violence is another major occupational health problem physicians increasingly face. Financial constraint, managed care and consumerism in health care are other factors that fundamentally change the role of physicians. The rapid deployment of new information technologies will also change the role of the physician towards being more of an advisor and information provider. Many of the minor health problems will increasingly be managed by patients themselves and by non-physician professionals and practitioners of complementary medicine. Finally, the economic and social status of physicians are challenged which is reflected in a slower salary increase compared to many other professional groups. The picture painted above may be seen as uniformly gloomy. In reality, that is not the case. There is growing interest in and awareness of the importance of the psychosocial work environment for the delivery of high quality care. Physicians under stress are more likely to treat patients poorly, both medically and psychologically. They are also more prone to make errors of judgment. Studies where physicians' work environment in entire hospitals has been assessed, results fed-back, and physicians and management have worked with focused improvement processes, have demonstrated measurable improvements in the ratings of the psychosocial work environment. However, it becomes clear from such studies that quality of the leadership and the physician team impact on the overall work atmosphere. Physicians unaware of the goals of the department as well as the hospital, that do not receive management performance feedback, and who do not get annual performance appraisals and career guidance, rate their psychosocial environment as more adverse than their colleagues. There is also a great need to offer personally targeted competence development plans. Heads of department and senior physicians rate their work environment as of higher quality than more junior and mid-career physicians. More specifically, less senior physicians perceive similar work demands as their senior colleagues but rate influence over work, skills utilization, and intellectual stimulation at work as significantly worse. In order to combat negative stressors in the physicians' work environment, enhancement initiatives should be considered both at the individual, group, and structural level. Successful resources used by physicians to manage the stress of everyday medicine should be identified. Physicians are a key group to ensure a well-functioning health care system. In order to be able to change and adapt to the ongoing evolution of the Western health care system, more focus needs to be put on the psychosocial aspects of physicians' work.Physicians Work environment Psychosocial Stress
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Interventions, training, and technologies for improved police well-being and performance
No full textInterventions, Training, and Technologies for Improved Police Well-Being and Performance is a critical publication that explores new training methods and technologies. The future of policing is poised to change, making the need for developments in evidence-based practices more important than ever before. New technology and techniques for improving performance and the perception of the police force can guide the policies and practices of law enforcement, trainers and academies, government officials, policymakers, psychologists, psychiatrists, therapists, to a more effective implementation of training and procedures. Including the perspective of police officers within the publication, this text offers insight into an often neglected viewpoint when creating training and policies
