Étude exploratoire sur le point de vue des enfants placés vivant l'expérience d'avoir des visites supervisées avec leurs parents

L’objectif de ce mémoire est de mieux comprendre, à partir de leur point de vue, le vécu des enfants âgés de 6 à 12 ans qui sont placés dans des ressources d’accueil et qui vivent l’expérience d’avoir des visites supervisées avec leurs parents. Pour ce faire, des entrevues semi-dirigées ont été réalisées auprès de douze enfants hébergés dans des unités de vie, foyers de groupe ou ressources intermédiaires du Centre jeunesse de Montréal – Institut Universitaire et du Centre jeunesse de la Montérégie. Les entrevues réalisées auprès des enfants ont été soumises à une analyse de contenu thématique. Les résultats de l’étude montrent que les enfants ne comprennent pas toujours bien les raisons qui justifient la mise en place de visites supervisées, ni le rôle des adultes dans les décisions, ni celui du tiers durant les visites. De façon générale, les enfants sont favorables au maintien des contacts avec leurs parents, mais sont plus critiques face aux cadres imposés par ces visites. Il ressort également de l’étude que les enfants sont très peu consultés en lien avec l’organisation et la planification de leurs visites et qu’ils souhaiteraient l’être davantage. Les enfants ont rapporté de nombreuses insatisfactions en lien avec les modalités organisationnelles des visites. L’analyse du discours qui a été menée a permis de mettre en évidence le fait que les visites supervisées sont une source de stress importante pour l’enfant. La création d’un guide d’information destiné aux enfants pour expliquer ce qu’est une visite supervisée, les raisons de sa mise en place, ses buts et ses objectifs serait une piste intéressante à explorer.

Tras las huellas de Hegemón : Usos de hegemonía en la teoría política de Ernesto Laclau

Este artículo presenta un análisis de la noción de hegemonía tal como es desarrollada por Ernesto Laclau en investigaciones que comprenden desde trabajos previos a su clásico Hegemonía y estrategia socialista. Hacia una radicalización de la democracia (1985, en colaboración con Chantal Mouffe) hasta su obra importante más reciente La razón populista (2004). La hipótesis de lectura que guía el articulo es que hegemonía -desde sus orígenes en la teoría política de Laclau- funciona como una categoría que plantea la relación entre la universalidad y la particularidad pero también como tres conceptos -en tanto esta categoría adquiere un contenido particular cuando se la utiliza en diferentes campos: lo político y la lógica de constitución de lo social; el funcionamiento de una/la lógica de la política; y la constitución de las identidades colectivas

Expression of biomineralization-related ion transport genes in Emiliania huxleyi

Biomineralization in the marine phytoplankton Emiliania huxleyi is a stringently controlled intracellular process. The molecular basis of coccolith production is still relatively unknown although its importance in global biogeochemical cycles and varying sensitivity to increased pCO2 levels has been well documented. This study looks into the role of several candidate Ca2+, H+ and inorganic carbon transport genes in E. huxleyi, using quantitative reverse transcriptase PCR. Differential gene expression analysis was investigated in two isogenic pairs of calcifying and non-calcifying strains of E. huxleyi and cultures grown at various Ca2+ concentrations to alter calcite production. We show that calcification correlated to the consistent upregulation of a putative HCO3- transporter belonging to the solute carrier 4 (SLC4) family, a Ca2+/H+ exchanger belonging to the CAX family of exchangers and a vacuolar H+-ATPase. We also show that the coccolith-associated protein, GPA is downregulated in calcifying cells. The data provide strong evidence that these genes play key roles in E. huxleyi biomineralization. Based on the gene expression data and the current literature a working model for biomineralization-related ion transport in coccolithophores is presented.

Risk technology in Australia: The role of the job seeker classification instrument in employment services

Promoted as the key policy response to unemployment, the Job Network constitutes an array of interlocking processes that position unemployed people as `problems' in need of remediation. Unemployment is presented as a primary risk threatening society, and unemployed people are presented as displaying various degrees of riskiness. The Job Seeker Classification Instrument (JSCI) is a `technology' employed by Centrelink to assess `risk' and to determine the type of interaction that unemployed people have with the job Network. In the first instance, we critically examine the development of the JSCI and expose issues that erode its credibility and legitimacy. Second, employing the analytical tools of discourse analysis, we show how the JSCI both assumes and imposes particular subject identities on unemployed people. The purpose of this latter analysis is to illustrate the consequences of the sorts of technologies and interventions used within the job Network.

Semi-analytical solution for nonlinear vibration of laminated FGM plates with geometric imperfections

This paper investigates the nonlinear vibration of imperfect shear deformable laminated rectangular plates comprising a homogeneous substrate and two layers of functionally graded materials (FGMs). A theoretical formulation based on Reddy's higher-order shear deformation plate theory is presented in terms of deflection, mid-plane rotations, and the stress function. A semi-analytical method, which makes use of the one-dimensional differential quadrature method, the Galerkin technique, and an iteration process, is used to obtain the vibration frequencies for plates with various boundary conditions. Material properties are assumed to be temperature-dependent. Special attention is given to the effects of sine type imperfection, localized imperfection, and global imperfection on linear and nonlinear vibration behavior. Numerical results are presented in both dimensionless tabular and graphical forms for laminated plates with graded silicon nitride/stainless steel layers. It is shown that the vibration frequencies are very much dependent on the vibration amplitude and the imperfection mode and its magnitude. While most of the imperfect laminated plates show the well-known hard-spring vibration, those with free edges can display soft-spring vibration behavior at certain imperfection levels. The influences of material composition, temperature-dependence of material properties and side-to-thickness ratio are also discussed. (C) 2004 Elsevier Ltd. All rights reserved.

Surveillance as a technique of power in physical education

This paper analyses surveillance as a technique of power in the culture of physical education, including its impact upon the health of teachers. Additionally, gendered aspects of surveillance are investigated because physical education is an important location in and through which bodies are inscribed with gendered identities. The embodied nature of physical educators' work renders the body as particularly significant in patterns of privilege and domination. The research was guided by Michel Foucault's work and poststructural feminist perspectives on the importance of power in social life. At nine schools across two international research sites, the functioning of surveillance was evidenced through the multi-directional workings of power in top-down, lateral, and bottom-up configurations. Data indicated that surveillance occurred on, through and about bodies. It had a strong gender dimension as the male gaze inscribed both female teachers' and students' bodies with value and competence. In terms of teachers' health, as well as responses to surveillance on a physical and emotional level, the workings of power were also influential in shaping teachers' identities.

Ptychogyliauchen, a new genus of Gyliauchenidae (Platyhelminthes: Digenea) from siganid fishes of the Indo-West Pacific

We propose a new genus of the Gyliauchenidae Fukui, 1929 ( Digenea), Ptychogyliauchen, gen. nov., for four new species that infect Indo-West Pacific siganid fishes. Ptychogyliauchen, gen. nov. is a morphologically distinctive genus, diagnosed principally by the presence of a highly convoluted oesophagus, which generally exceeds the total body length of the worm, and by the unusual folded structure of the ejaculatory duct. Ptychogyliauchen thetidis, sp. nov. is designated as the type species, and is described from the intestine of Siganus punctatus (Siganidae) from Heron Island, Great Barrier Reef, Queensland, Australia. Ptychogyliauchen himinglaeva, sp. nov. is described from the intestine of Siganus corallinus ( Siganidae) from Lizard Island, Great Barrier Reef, Queensland, Australia. Ptychogyliauchen leucothea, sp. nov. is described from the intestine of S. argenteus, and further recorded from S. fuscescens, off Ningaloo, Western Australia, Australia. Ptychogyliauchen thistilbardi, sp. nov. is described from the intestine of S. doliatus from Noumea, New Caledonia, and is also found in S. argenteus, S. canaliculatus, S. corallinus and S. spinus from Noumea, New Caledonia, and Moorea, Tahiti, French Pacific. Ptychogyliauchen thistilbardi, sp. nov. also occurs in the intestine of Chaetodon citrinellus (Chaetodontidae) from Moorea. A key to species is provided. All species have been described following morphological examination using light microscopy, and specimens of P. thetidis, sp. nov., P. leucothea, sp. nov. and P. thistilbardi, sp. nov. have been characterised using molecular methods. Sequences were obtained for a combination of nuclear ribosomal (28S (D1-D3) and ITS2) and mitochondrial (ND1) genes. A phylogenetic analysis of sequenced specimens of Ptychogyliauchen, gen. nov. was conducted using species of Petalocotyle Ozaki, 1934 for outgroup comparison. This analysis, based on alignments of the ITS2 and 28S (D1-D3) rDNA genes, supports monophyly of the geographically widespread P. thistilbardi, sp. nov., which is known from both siganid and chaetodontid hosts. We discuss the taxonomy of the genus and the host associations of each species and the group.

Women are silver, women are diamonds: Conflicting images of women in the Cambodian print

This paper examines 116 articles related to sexual and reproductive health translated into English from the Khmer press from April 1997 to February 2004. These excerpts were found in The Mirror, a publication of the non-governmental organisation Open Forum of Cambodia, which collates Grid reviews all issues of the Khmer press on a weekly basis. Five major themes were identified: the politics of women's health, government regulation and control, the sex industry in Cambodia, rape, and the HIV epidemic. Discourse analysis of these articles in the context of other sources and experience allows a gendered exploration of the reporting of sexual and reproductive health and rights issues in Cambodia by the Khmer print media. The reports explore the contested political empowerment of women in this strongly hierarchical society, and the mechanisms used to regulate and control sexual activity. The expanding sex industry and associated sexual trafficking ore reported, together with the corruption of legal structures designed to regulate health systems and protect women and children from sexual exploitation and rope. The growing problem of AIDS and successes in reducing HIV transmission through the collaboration of sex workers in the 100% condom use policy is documented, and the tensions implicit in G Cultural representation of women that both protects and constrains women ore explored.

Managerialism and Public Housing Reform

This paper discusses market inspired changes to the delivery of public housing in Queensland, Australia during the late 1990s. These policy changes were implemented in an organisational environment dominated by managerialism. The theory and method of critical discourse analysis is used to examine how managerial subject positions were assimilated and/or creatively resisted by different actors within the public housing policy community. These themes are discussed using interview data with a range of policy actors, including policy managers, front-line housing staff and public housing tenants. The analysis suggests that policy actors who openly challenged the emerging policy and organisational direction were marginalised in changing power relations.

Agency as discursive practice: From nobody to somebody as an international student in Australia

As more and more students pursue an international education, there is a need to investigate how these students deal with the demands of their study programs in the new academic context. This paper introduces one such student, a Thai English teacher named Woody,2 and looks at the ways that he engaged with a Master of Education program in Australia. I analyse the transcripts of two interviews that I conducted with Woody in his first semester using Fairclough's model of Critical Discourse Analysis (CDA). The analysis is interested in the social and institutional demands that Woody identified as impacting on the course, and the strategic action that he took in response to them. I argue that by undertaking this action, Woody was “working” as an agent of his own change. The analysis highlights a proactive and strategic engagement on Woody's part, a point that has been missed in much of the literature on the international student experience in Australia.

Mapping the notion of "terrorism" in Serbian and Croation newspapers

The September 11 terrorist attacks in the United States have reconfigured the global public debates as of how to defend a "civilized" world from the "Islamic terrorism." The U.S.-led war on terror against extremist groups also produced and triggered a particular discourse in the former Yugoslav countries. The main aim of this article is to present an example of a study that explores how media appropriate dominant global antiterrorism discourse and apply it to a local context to legitimize and justify specific ideologies and discourse. As our critical discourse analysis shows, Serbian and Croatian newspapers apply the global discourse of terrorism to their local context to excuse their nationalisms and the past military actions against the Muslims in former Yugoslav wars, and with that, they assert their belonging to an antiterrorism global discursive community. © 2006 Sage Publications.
