Margaret Archer has recently provided a persuasive account of the importance of the internal conversation to reflexivity. This raises questions about the shaping of such conversations by involuntary agential positioning. The work of Bourdieu and Bernstein is reviewed to suggest that structural influences can operate by condi-tioning the resources available for the conducting of the internal conversation. Particular emphasis is placed on the transfer of taken for granted ideas from one domain of practice to another.  相似文献

In the last two decades, transnational social fields have been transformed by advances in information and communication technologies (ICT). Many scholars have noted the empowering effects of these technological advances for migrants. Drawing on the concept of return preparedness, it follows that ICT use should also empower prospective returnees, enabling them to be better informed and prepared for return. However, multi‐sited ethnographic research with older North and West African men living in migrant worker hostels in France finds that ICT use – particularly mobile telephony –impedes return. In some instances, mobile phones serve to amplify the pressures on the men to provide financially for their stay‐at‐home relatives. In others, mobile phones reinforce attachments to France by facilitating networks of solidarity among hostel residents. Instead of returning definitively at retirement, many hostel residents choose a bi‐residence strategy, dividing their time between France and countries of origin.  相似文献

Abstract. In this article, we estimate the parameters of a simple random network and a stochastic epidemic on that network using data consisting of recovery times of infected hosts. The SEIR epidemic model we fit has exponentially distributed transmission times with Gamma distributed exposed and infectious periods on a network where every edge exists with the same probability, independent of other edges. We employ a Bayesian framework and Markov chain Monte Carlo (MCMC) integration to make estimates of the joint posterior distribution of the model parameters. We discuss the accuracy of the parameter estimates under various prior assumptions and show that it is possible in many scientifically interesting cases to accurately recover the parameters. We demonstrate our approach by studying a measles outbreak in Hagelloch, Germany, in 1861 consisting of 188 affected individuals. We provide an R package to carry out these analyses, which is available publicly on the Comprehensive R Archive Network.  相似文献

Après avoir recueilli dans la littérature de l'écologie sociale un ensemble de propositions obtenues par Panalyse factorielle, on procéda à les verifier en utilisant une stratégie polyvalente de recherche sur des données longitudinales provenant de Winnipeg. II semble que la structure écologique de cette ville peut être décrite en utilisant trois variables générales et cela correspond aux attentes. Ces variables sont: le statut économique, le statut familial, et le statut d'immigration; ajoutons, toutefois que certaines de ces variables acquièrent une importance qui se distingue de celle que l'on retrouve dans les études américaines sur le même sujet. Contrairement aux previsions, toutefois, l'importance relative du statut économique diminue avec le temps bien que son importance absolue ait gardé une valeur constante. L'importance relative et absolue du statut familial s'est accrue tandis que celle du statut d'immigrant s'est abaissée. Au surplus, les données suggèrent qu'avec le temps la différenciation écologique s'atténue plutôt que de s'accroître. A certains égards ces résultats contredisent les prévisions générées par les études antérieures et les théories de l'écologie urbaine et soulèvent plusieurs problèmes d'interprétation. A set of propositions is gleaned from the literature in the social area analysis-factorial ecology tradition, and tested using a new multi-method research strategy applied to longitudinal data gathered for Winnipeg. Generally consistent with what was expected, it would appear as if the ecological structure of this city can be described in terms of three general constructs: economic status, family status, and immigrant status, although certain of these constructs differed in important ways from their counterparts in studies of us cities. Contrary to what was expected, however, the relative importance of economic status seems to have declined over time, although its absolute importance has remained quite constant. The relative (and absolute) importance of family status has increased, while the converse has happened with regard to immigrant status. In addition, the evidence suggests that the over-all level of ecological differentiation may be decreasing over time, rather than increasing. These results run counter in several respects to predictions generated from current research and theory in urban ecology, and pose a number of interesting and difficult problems of interpretation.  相似文献

Correspondence to Bill Whyte, Lecturer in Social Work, Department of Social Policy and Social Work, Adam Ferguson Building, University of Edinburgh, George Square, Edinburgh EH8 9LL. Summary There has been a renewed interest in recent years on the purposeof Guardianship but only limited empirical data on how it isbeing used under the current Mental Health legislation. Thispaper attempts to address both issues. The paper presents someof the findings of a Scottish study which examines the implicationsof this legislation and covers a range of issues including usesof Guardianship; a profile on the Mental Health Officers (ApprovedSocial Workers) involved and their role in assessment; who becamethe guardian and how they exercised their role; and broaderlegal issues. Unlike a recent paper (Evans, 1989) the authorsbelieve the legislative framework is inadequate to promote initiativeand good practice in this field and that there is a need fora new debate on the purposes of Guardianship with particularreference to the powers needed to care for and protect a rangeof adults with differing needs who might be considered ‘atrisk’ in the community.  相似文献

Nous servant des sondages faits sur les élections nationales canadiennes de 1965 et 1968, nous développons l'analyse d'ogmundson sur l'esprit de vote des différentes classes sociales, dans l'enquête de 1965. Dans son étude, il comparait les résultats obtenus quand les orientations de classes des partis politiques étaient formulées de trois façons possibles: d'après les jugements des experts, d'après la moyenne des évaluations données par les répondants du sondage de 1965, et d'après les estimations idiosyncratiques de chaque répondant. Les deux derniers critères étaient pris des évaluations de chaque parti, selon une échelle sémantique à sept points, qui avait, comme points axiaux: “pour la classe moyenne” opposéà“pour la classe ouvrière.” Notre analyse répond à trois questions: premièrement, si les découvertes de base d'Ogmundson pour 1965 tiennent pour 1968; deuxièmernent, si les évaluations sur les partis par les répondants, d'aprés une deuxième échelle établie parles points “de gauche” opposées à“de droite,” donnent des résultats comparables, aussi bien sur les échelles que dans les sondages. Finalement, en utilisant une analyse de facteur, s'il y a, sur l'ensemble de treize échelles employées dans chaque enquête, quelque évidence d'un facteur de classe dans les évaluations données aux partis. La réponse est affirmative pour la première question et négative pour la seconde. Dans le cas de la troisième, un seul facteur fixe apparaît pour chaque parti, comme décrit par ses électeurs. La structure de ce facteur est commune à tous les partis dans les deux élections, et cela n'a pas grand chose à faire avec les orientations de classe perçues par les répondants. On explore toujours les implications théoriques de ces données. Using the 1965 and 1968 Canadian national election surveys, we extend Ogmundson's analysis of the “class” vote in the 1965 survey. He compared the results obtained when the class orientations of political parties were defined in three alternative ways: according to the judgments of experts: according to the mean ratings given by respondents in the 1965 survey; and according to each respondent's idiosyncratic ratings. The latter two criteria were taken from ratings of each party along a 7–point semantic differential-type scale which had as its end points “for the middle class” v. “for the working class.” Our analysis answers three questions: first, whether Ogrnundson's basic findings for 1965 hold also for 1968: second, whether respondents' ratings of the parties along a second scale anchored by “left-wing” v. “right-wing” yield comparable results across scales and Surveys; third, using factor analysis, whether there is any evidence for a class-based theme in the ratings given parties on the set of thirteen scales employed in each survey. The answer is affirmative to the first question and negative to the second question. In the case of the third question, a single unrotated factor emerged for each party as described by its voters. The structure of this factor was common to all parties in both elections, and it appeared to have very little to do with their perceived class orientations. Theoretical implications of these findings are explored.  相似文献
