Studying International Migration in the Long(er) and Short(er) Duree: Contesting Some and Reconciling Other Disagreements Between the Structuration and Morphogenetic Approaches

The essay contests some and reconciles other disagreements between the structuration and morphogenesis approaches?the two models in present-day sociology which aim at bridging the macro-micro gap in social theorizing, but whose advocates have been either indifferent to or at open odds which each other instead of engaging in a close intellectual collaboration. The empirical illustrations of my arguments come from local statistical surveys and ethnographic studies conducted in Polish villages from the onset to the decline of mass transatlantic migration in the period 1870s-1930s

Composite meaning, flexible ranges, and multi-level conditions of conviviality: Exploring the polymorph

In this article, I present, first, a composite definition of conviviality whose constitutive components are conceived in terms of degrees rather than as present-or-absent conditions. Next, I offer a preliminary list of macro-, micro- and individual-level circumstances which co-shape conviviality into different arrangements and intensities. Within the framework of the structuration theory which informs my discussion, I then identify the characteristics of cultures of conviviality as different from the orientations and practices of the individuals who (re)create them, and I propose a distinction between the conditions contributing to the emergence of cultures of conviviality and the circumstances responsible for their endurance over time. In the last part of the article, I identify different goals of case-based investigations and propose some strategies of comparative analysis of the contributing circumstances and different forms and ?contents? of conviviality, and I illustrate it with examples taken from my previous studies of ground-level multiculturalism in different locations

Face Masks and Cough Etiquette Reduce the Cough Aerosol Concentration of Pseudomonas aeruginosa in People with Cystic Fibrosis

People with cystic fibrosis (CF) generate Pseudomonas aeruginosa in droplet nuclei during coughing. The use of surgical masks has been recommended in healthcare settings to minimize pathogen transmission between patients with CF.To determine if face masks and cough etiquette reduce viable P. aeruginosa aerosolized during coughing.Twenty-five adults with CF and chronic P. aeruginosa infection were recruited. Participants performed six talking and coughing maneuvers, with or without face masks (surgical and N95) and hand covering the mouth when coughing (cough etiquette) in an aerosol-sampling device. An Andersen Cascade Impactor was used to sample the aerosol at 2 meters from each participant. Quantitative sputum and aerosol bacterial cultures were performed, and participants rated the mask comfort levels during the cough maneuvers.During uncovered coughing (reference maneuver), 19 of 25 (76%) participants produced aerosols containing P. aeruginosa, with a positive correlation found between sputum P. aeruginosa concentration (measured as cfu/ml) and aerosol P. aeruginosa colony-forming units. There was a reduction in aerosol P. aeruginosa load during coughing with a surgical mask, coughing with an N95 mask, and cough etiquette compared with uncovered coughing (P

Cornish identities and migration: a multi-scalar approach

The definitive version is available at www.blackwell-synergy.com. 24 month embargo by the publisher. Article will be released July 2009.In this article we argue that theories of transnationalism have value in exploring the historical context of migration and that historical contexts help to shape such theoretical conceptualizations. Historians of migration have now begun to engage more directly with the literature of transnationalism, focusing on the networks that linked settler and home communities. Here we add to this by examining a nineteenth-century migrant community from a British region through the lens of transnationalism, applying the concept to the case of the Cornish, whose economic specialization produced culturally distinct Cornish communities on the mining frontiers of North America, Australia and South Africa. In doing so, we bring together the issues of scale and time. We review the multiple levels of the Cornish transnational space of the late nineteenth century, which exhibited aspects of both core transnationalism and translocalism. This waned, but in the later twentieth century, a renewed interest in a transnational Cornish identity re-emerged, articulating with changing identity claims in Cornwall itself. To capture better the experience of the Cornish over these two very different phases of transnationalism we identify another subset of transnationalism - that of transregionalism.Leverhulme Trus

Securitization and Community-Based Protection Among Chin Refugees in Kuala Lumpur

This article examines refugee-led community organizations among Chin refugees from Myanmar in Kuala Lumpur. It uses a structuration analysis that recognizes refugee-led organizations as complex governance entities engaged in a dynamic relationship with (among others) national policies of securitization of forced migration and international humanitarian governance. This approach expands the existing literature on the securitization of forced migration by exploring refugees’ lived experiences in a context of south–south migration. It expands the literature on community-based protection by going beyond recognizing the existence of refugee-led organizations to analyse their construction, constitution and consequences. Three primary areas of work by Chin refugee groups are analysed in relation to their immediate activity and longer term effects: organization (‘building ethnic unity in adversity’), documentation (‘asserting a bureaucratic identity’) and socialization (‘learning to be illegal’). These long-term effects indicate the possible impact of local protection activities on macrostructural processes such as identity construction and migration choices.construction, constitution and consequences.

An Attempt to Apply the Servqual Method to Evaluate the Quality of an E-course

The challenge faced by e-learning is to ensure its quality. In addition to traditional methods of quality assurance, there is an increasing tendency to use tools and techniques from other disciplines. The paper presents the possibility of application of the SERVQUAL method in assessing the quality of an e-course. The method and the main stages of the examination have been characterized. A survey was used to assess the expected and the perceived quality of an e-course. Exemplary results have been presented. The Servqual method allows to identify the discrepancies that may arise between the expectations of the student and his perception of the e-course. The methodology can allow to make improvements to the e-course
