The advent of thousands of Usenet groups on the Internet, covering a vast range of medical and welfare issues and ostensibly devoted to the mutual social support of participating members, has raised the potential for the development of new forms of 'virtual' health care. This article critically analyses the use by people with diabetes of one such Usenet group. It seeks to establish, first, the extent to which such a site provides some demonstrable measure of social support to its participants. This is approached by undertaking a structural analysis of the site to identify the extent of usage, and the nature of supporting interventions using a fivefold classification (instrumental, informational, esteem and social companionship and other). Second, the article attempts to identify any disparity between the lay health-knowledge in evidence and biomedical opinions proffered by the use of a panel of consultant diabetiologists. The results of the analysis suggest that the diabetes newsgroup provides an example of an active forum for largely well-informed participants who routinely use the media as an aid to the reflexive management of their medical condition. It also raises the prospect of a renegotiated relationship between medical knowledge and lay experience based upon shared learning  相似文献

The completely random character of radioactive disintegration provides the basis of a strong justification for a Poisson linear model for single-photon emission computed tomography data, which can be used to produce reconstructions of isotope densities, whether by maximum likelihood or Bayesian methods. However, such a model requires the construction of a matrix of weights, which represent the mean rates of arrival at each detector of photons originating from each point within the body space. Two methods of constructing these weights are discussed, and reconstructions resulting from phantom and real data are presented.  相似文献

Migration and development are linked in many ways – through the livelihood and survival strategies of individuals, households, and communities; through large and often well–targeted remittances; through investments and advocacy by migrants, refugees, diasporas and their transnational communities; and through international mobility associated with global integration, inequality, and insecurity. Until now, migration and development have constituted separate policy fields. Differing policy approaches that hinder national coordination and international cooperation mark these fields. For migration authorities, the control of migration flows to the European Union and other OECD countries are a high priority issue, as is the integration of migrants into the labour market and wider society. On the other hand, development agencies may fear that the development policy objectives are jeopardized if migration is taken into consideration. Can long–term goals of global poverty reduction be achieved if short–term migration policy interests are to be met? Can partnership with developing countries be real if preventing further migration is the principal European migration policy goal? While there may be good reasons to keep some policies separate, conflicting policies are costly and counter–productive. More importantly, there is unused potential in mutually supportive policies, that is, the constructive use of activities and interventions that are common to both fields and which may have positive effects on poverty reduction, development, prevention of violent conflicts, and international mobility. This paper focuses on positive dimensions and possibilities in the migration–development nexus. It highlights the links between migration, development, and conflict from the premise that to align policies on migration and development, migrant and refugee diasporas must be acknowledged as a development resource.  相似文献

This study examined the unique and interactive roles of mother and teacher depressive symptoms in child adjustment in 277 African American single mother‐headed families, as well as whether the associations differed depending on the age and gender of the child. Findings revealed a significant association between maternal depressive symptoms and child depressive symptoms in girls, but not boys. Moreover, the combination of higher levels of both mother and teacher depressive symptoms was associated with the highest level of child depressive symptoms and, for younger children, externalizing symptoms. The importance of considering the multiple social contexts in which children interact is discussed.  相似文献

The aim of the study was to explore the degree (and type) of burnout and trauma symptoms, personal histories and coping strategies retrospectively reported by those who work with maltreated children and their families. A self‐selected sample of workers (N = 44) completed a self‐report questionnaire assessing childhood maltreatment, family background characteristics, current adjustment, coping strategies and burnout. Workers reported high levels of emotional exhaustion and depersonalization, and a low to moderate sense of personal accomplishment. Family background characteristics predicted the occurrence of maltreatment and current adjustment, and a personal history of maltreatment predicted current trauma symptoms, but not burnout. Workers most frequently used problem‐focused coping strategies and sought social support; however, coping strategies were not associated with the level of either trauma symptoms or burnout. Despite employing positive coping strategies, their efficacy may be affected by other interpersonal, intra‐individual and job resource issues. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

The article begins with the realist assumption in political science that posits that political violence and chaos occurs in the absence of the state, and that the international system is congenitally anarchic. Using the Y2K problem and the 11 September 2001 attack on the World Trade Center in New York as two instances of violent political phenomena within global modernity, this article examines notions of citizenship, pluralism, and their relationships with modern public space through the lens of 'public disaster' scenarios in which the breakdown of centralized systems of power tends to lead to chaos. However, public disasters also appear to create the opposite effect of bonding communities together in the face of adversity that leads to greater social cohesion rather than the breakdown of social institutions. The article tries to resolve this apparent enigma through several theories of public space, democracy, and civil society.  相似文献

Zusammenfassung  Der Beitrag beschreibt Planung, Verlauf und abschlie?ende Beurteilung eines gruppendynamischen Seminars, in dem für angehende Supervisorinnen und Supervisoren das Thema Organisations-Entwicklung dargestellt und vermittelt werden sollte. Ausgangspunkt war die Kl?rung des Inhaltsraums von Organisations-Entwicklung als geplantem sozialen Wandel, der auf sozialwissenschaftlicher Grundlage zielgerichtet, strategisch und mit Zeitperspektive in der Zusammenarbeit zwischen externer und interner Sach-, Prozess- und Entscheidungskompetenz durchgeführt wird. Als Ziele des Seminars wurden festgelegt, Organisations-Entwicklung als sozialwissenschaftliches Instrument zu begründen, Organisations-Entwicklung-Schritte zu konzipieren und sie kollegial zu kommunizieren. Darüber hinaus wurden Qualit?tskriterien für das Seminar formuliert: Praxisn?he, Kl?rung des Inhaltsraum Selbstorganisation, Selbststeuerung, Ressourcenaktivierung, Konfliktregulierung, Analyse des Gruppenprozesses, Nutzung von Feldkompetenz und Verhaltensmodellen, Etablierung von Feedbackschleifen, Koordination und Synergie, kollegialer Austausch und Kl?rung pers?nlicher Organisations-Entwicklungs-Fragen. Bausteine und Lernorte des Seminars waren das Plenum, die Lernpartnerschaft, das OE-Team, die Beobachterfunktion, die Tagesreflexion, die Sitzung Frage und Antwort, die Darstellung von Praxisf?llen, das Plenum-Feinsteuerung, die Analyse der Arbeitsprozesse des OE-Teams sowie Transfer und Auswertung. Der tats?chliche Verlauf des Seminars wird aus der Perspektive des Leiters kommentiert. Anhand von Verlaufsbeobachtungen und Teilnehmer?u?erungen wird der Eindruck begründet, dass diese Form des Vorgehens als lernintensiv, autonomief?rdernd und für die zu erwerbende Supervisionskompetenz als praxisrelevant betrachtet werden kann.
This article describes the plantification, progress and final evaluation of a group-dynamic seminar for future supervisors in which the topic organization development was presented and introduced. The content of organization development was first defined as a planned social change which is executed based on social sciences in a goal-oriented, strategic way which considers the time perspective of the cooperation between external and internal specialised-, process- and decision competence. Goals of the seminar were to justify that organisation development is a social science tool, to plan organization development steps and to communicate them to peer seminar participants. Further more, the following quality criteria for the seminar were formulated: practice orientation, definition of self-organisation content, self regulation, resources activation, conflict regulation, group process analysis, field competence and behaviour models usage, feedback establishment, coordination and synergy, mutual peer exchange and finding answers to personal questions about organization development. The building blocks and learn places of the seminar were the plenary sessions, the learning partnership, the od-teams, the observer function, the day analysis, the questions and answers session, the case study presentation, the analysis of the work processes as well as transfer and evaluation. The progression of the seminar is commented from the point of view of the seminar leader. Progress observations and participant’s feedback justify the impression that this way to conceptualise provides an intensive learning experience, supports autonomy and provides relevant and practical supervision competence.
