This paper unfolds a conceptual framework of migrants' transnational engagements. It combines three elements: a concept of social agent apprehended in its plurality of roles and social embedding; the Habermas theory of communicative action accounting for the communicative dimension of transnational engagements; a concept of social institution explaining the role of migrant organizations in framing transnational activities. This framework is applied to the analysis of cross border engagements of Moroccan, Algerian and Indian hometown organizations in the development of their respective sending areas.  相似文献

This piece argues for the importance of critical engagements with photographs in order to explore and rethink the past, to reflect on the present and to imagine the future. It provides a brief overview of the articles that constitute the first part of the Social Dynamics special issue on photography in Africa, a collection that contributes to the growing body of scholarship that deepens our understandings of the significance of photography on the continent.  相似文献

There is a growing literature investigating the association between coping and work stress among social workers. An area that remains under-researched is the association between work–family conflict and coping. The present study explored the coping strategies adopted by social workers in dealing with the competing demands emanating from their work and family domains. In a larger study involving 439 Australian social workers, we analyzed the responses to two open-ended questions that explored the challenges experienced by social workers in meeting their work and family demands, and the coping strategies they adopt to deal with these challenges. The findings confirm that social workers experience work–family conflict and they adopt several coping strategies to deal with it including support from supervisors and colleagues, cognitive reframing, timely communication, setting clear expectations, time management, job flexibility and developing personal hobbies. We discuss the implications of our findings for social work policy and practice.  相似文献

Disability Studies has begun to interrogate the aesthetics of disability, both in terms of artwork and sensuous apprehension more generally. The present paper is a contribution to this burgeoning literature. Here I seek to demonstrate what the aesthetics of Martin Heidegger offer to that project. I do so in three stages. I begin by reviewing some relevant disability studies literature, highlighting some general themes in Disability Studies’ recent engagement with ‘the aesthetic’, widely defined. Next, I turn to the phenomenology of Martin Heidegger, to add some further philosophical depth to this project. In third and final section, I apply Heidegger’s aesthetics to the recently unveiled thalidomide memorial, to demonstrate the empirical worth of his analysis of artwork. I conclude with suggestions for future Disability Studies.  相似文献

Specific efforts by hospital accreditation organizations encourage renovation of nursing stations, so nurses can better see, attend, and care for their patients. The purpose of this study was to examine the effect of nursing station design on the therapeutic milieu in an adult acute care psychiatric unit. A repeated cross-sectional, pretest-posttest design was used. Data were collected from a convenience sample of 81 patients and 25 nursing staff members who completed the Ward Atmosphere Scale. Pretest data were collected when the unit had an enclosed nursing station, and posttest data were collected after renovations to the unit created an open nursing station. No statistically significant differences were found in patient or staff perceptions of the therapeutic milieu. No increase in aggression toward staff was found, given patients' ease of access to the nursing station. More research is needed about the impact of unit design in acute care psychiatric settings.  相似文献

Although some attempts are being made to increase children's participation in Norwegian child protection cases, much needs to be done in order to comply with the participation principle in the United Nations Convention on the Rights of the Child. This paper reports on a study of factors that are likely to predict if social workers will attempt to give children an effective voice in decision making processes. 53 child protection case managers and 33 social work students participated in a questionnaire survey in which they were asked to agree or disagree with 20 statements about child participation. Statistical factor analysis was used in order to identify underlying factors in the dataset. The results suggest three main reasons for children not being allowed to participate: communication difficulties (communication factor); because child participation was not deemed necessary (participation advocacy factor); or that participation was considered inappropriate because it might be harmful (protectionism factor). This research suggests that, if we are to improve participation within the child protection system, formal regulations and guidelines need to be accompanied by a greater attention to development of social work skills in working with children through participatory processes.

The operating microscopes may be a significant cause of fatigue and discomfort in surgeons. The need for the microscope to be placed over the operating field forces surgeons to remain at the microscope's eyepieces at an uncomfortable posture for the entirety of the surgery. This study compared the effects on microsurgical task performance for four visualization methods: a monocular microscope, a binocular microscope, a three-dimensional (3D) flat-panel television display and a two-dimensional (2D) flat-panel television display. Eleven subjects each performed two microsurgical tasks and their performance was documented by video camera. The statistical analysis performed indicated utilization of the microscope as a visualization method increased subject performance. No significant difference in performance between the 2D and stereoscopic visualization methods.  相似文献

Augmented Reality focuses on the enrichment of the user's natural field of view by consistent integration of text, symbols and interactive three-dimensional objects in real time. Placing virtual objects directly into the user's view in a natural context empowers highly dynamic applications. On the other hand, this necessitates deliberate choice of information design and density, in particular for deployment in hazardous environments like military combat scenarios. As the amount of information needed is not foreseeable and strongly depends on the individual mission, an appropriate system must offer adequate adaptation capabilities. The paper presents a prototypical, vehicle-mountable Augmented Reality vision system, designed for enhancing situation awareness in stressful urban warfare scenarios. Tracking, as one of the most crucial challenges for outdoor Augmented Reality, is accomplished by means of a Differential-GPS approach while the type of display to attach can be modified, ranging from ocular displays to standard LCD mini-screens. The overall concept also includes envisioning of own troops (blue forces), for which a multi-sensor tracking approach has been chosen. As a main feature, the system allows switching between different information categories, focusing on friendly, hostile, unidentified or neutral data. Results of an empirical study on the superiority of an in-view navigation cue approach conclude the paper.  相似文献

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.  相似文献
