La sous-traitance « boomerang » : l’influence des relations industrielles sur l’internalisation d’activités manufacturières confiées en sous-traitance

Au cours de la dernière décennie, le secteur manufacturier québécois a subi d’importantes transformations. La mondialisation ayant amené les entreprises à restructurer leurs activités, 96% des établissements manufacturiers québécois ont choisi d’avoir recours à la sous-traitance (Jalette, 2004). Or, nous savons que l’octroi de contrats en sous-traitance est un processus qui se révèle parfois décevant pour les entreprises. En raison de l’évolution de certains facteurs organisationnels internes ou externes qui contribue à changer le contexte au sein duquel les décisions de sous-traitance avaient été prises initialement (ex. : augmentation des coûts de main-d’œuvre et de transport, changements technologiques), il arrive que les entreprises renversent les décisions de sous-traitance par une décision d’internalisation (OCDE, 2013). Le concept d’internalisation réfère ici à l’action d’une entreprise de ramener vers un établissement des activités de production qui avaient été antérieurement transférées en dehors de celui-ci, et ce, que ce soit en raison d’une sous-traitance d’activités à une entreprise indépendante ou d’une délocalisation au sein d’un autre établissement de l’entreprise (Jalette & Chevance, 2008). La présente étude a pour objectif d’expliquer la décision managériale d’internalisation par le biais des dynamiques sociales inhérentes aux relations industrielles, en allant au-delà des seuls facteurs économiques. L’effet sur l’internalisation de quatre variables indépendantes liées aux relations industrielles est étudié, soit la capacité stratégique du syndicat local, la solidarité interne de l’acteur syndical local et sa solidarité externe, ainsi que le climat des relations patronales-syndicales. La typologie des positions syndicales de Jalette (2005), le modèle des ressources de pouvoir syndicales de Lévesque et Murray (2003) et les travaux de Dastmalchian (2008) traitant du climat des relations industrielles constituent le cadre théorique de cette recherche. La présente étude utilise des données recueillies dans le cadre d’une enquête par questionnaire réalisée en 2005 auprès de présidents de syndicats locaux affiliés à la CSD et à la FTQ qui œuvrent dans le secteur manufacturier québécois. L’étude révèle que 24% des syndicats locaux sondés ont vécu l’internalisation d’activités antérieurement sous-traitées dans les deux années précédentes au sondage. De plus, les résultats sont à l’effet que les chances d’internalisation d’activités augmentent lorsque plusieurs stratégies et actions visant l’internalisation sont adoptées par le syndicat local, lorsque la vie syndicale d’un syndicat local s’améliore et lorsque le temps de libération syndicale d’un syndicat local augmente. Toutefois, les chances d’internalisation d’activités diminuent lorsque le rapport de force d’un syndical local augmente. L’internalisation d’activités diminue également lorsque le climat des relations du travail se détériore. Bref, les résultats de cette recherche montrent que les syndicats n’ont pas qu’à subir la mondialisation et que, par leurs actions, ils sont à même d’en influencer le cours, notamment en favorisant l’internalisation d’activités antérieurement confiées en sous-traitance.

Repositioning drama to centre stage: drama, English, text and literacy

A version of this article was first presented at the Drama Australia Conference, Fremantle, July 2002. It draws upon Freebody and Luke's four resources literacy framework, where they describe four kinds of literacy  practices. It shows how this model is used within the literacy community and argues that this model is useful to describe the contribution that drama can make to literacy development. Freebody and Luke's model is used and  promoted throughout Australia and the author argues that it is politically astute for drama teachers to reclaim and promote their links to the English/Literacy curriculum.

Teachers' work hours, work-family conflict and health: the mediating effects of perceived control and organisational support

Teachers are among those working longer hours more than ever before. the implications of these long hours on teachers' health, through work-family conflict, control over hours worked and organisational support were investigated. 120 teachers, of whom 91 (59.3% female) reported
working in excess of 37 1/2 hours in the week prior, participated in the study. Long hours, work-family conflict, control and organisational support, explained 69% of the variance in health. There was no direct effect of long worked hours on health however long hours did have a direct impact on work-family conflict, organisational support, and control and, through
these, teachers' health. Work-family conflict exerted a direct negative impact on health. These findings are discussed in individual and organisational tenns.

Putting literacy in the middle: key learnings from the middle years literacy research project

This article discusses the Middle Years Literacy Research Project and its design. The authors report on key findings and recommendations from the research. In particular the authors look at what is distinctive about teaching adolescent learners in middle years and what does the research show that is distinctive about teaching, the ways that literacy is understood and talked about, its various positioning in the middle years and, connections between effective literacy and effective learning. The article describes a Four Resources model as a framework for literacy teaching and learning for middle year education; literacy leadership, coordination, professional development and collaborative partnerships; and, what school strategies have the most potential to bring about long-term change and improvement in students' literacy and learning outcomes.

Police stress : the role of psychological contract and perceptions of fairness

Purpose – The overall purpose of this paper is to examine the extent to which breaches in psychological contracts and perceptions of organizational fairness account for variations in job stress experienced by operational police officers (as measured by psychological distress and employee performance), after controlling for the variance associated with more established job stressors (i.e. job demands, job control and social support).

Design/methodology/approach – This study is based on data collected through a self-report survey involving operational members of a large Australian police force (n=582).

Findings – Results of hierarchical multiple regression analyses indicate that vast majority of explained variance in psychological distress and extra-role performance is attributed to the additive effects of demand, control, and support. Furthermore, only one of the social exchange dimensions (interpersonal fairness) is predictive of either target variable.

Research limitations/implications – The limitations that need to be taken into account are the cross-sectional nature of the study design and the focus on a single police service.

Practical implications – Despite the generally weak support for the social exchange variables, there are signs that dimensions of justice (particularly interpersonal justice) should be included in future police-stress investigations. The results also suggest that job characteristics such as job demand, job control and social support should be taken into account when developing strategies to prevent and/or reduce chronic job stress in policing services.

Originality/value – This is one of the first studies to examine the relationships between psychological contract breach, perceptions of fairness and police stress.

IaaS clouds vs. clusters for HPC: a performance study

The increasing amount of data collected in the fields of physics and bio-informatics allows researchers to build realistic, and therefore accurate, models/simulations and gain a deeper understanding of complex systems. This analysis is often at the cost of greatly increased processing requirements. Cloud computing, which provides on demand resources, can offset increased analysis requirements. While beneficial to researchers, adaption of clouds has been slow due to network and performance uncertainties. We compare the performance of cloud computers to clusters to make clear the advantages and limitations of clouds. Focus has been put on understanding how virtualization and the underlying network effects performance of High Performance Computing (HPC) applications. Collected results indicate that performance comparable to high performance clusters is achievable on cloud computers depending on the type of application run.

Is there an app for that? Looking at possibilities and challenges of digital tools for literacy education

 Portable electronic devices such as the iPad are increasingly taking a place in contemporary childhood experiences including those of schooling (O'Mara & Laidlaw, 2011). As digital media theorists suggest, such new tools invite both "hope and fear" (Gee and Hayes, 2011, p.4), consistent with literacy innovations across history. In both Canada and Australia, educational stakeholders are looking to touch screen devices as having much promise, particularly within literacy education. This paper presentation examines the possibilities as well as the challenges and imagines the future of such digital tools within literacy education, looking at experiences and perspectives in Canada and Australia.
We take a qualitative ecological mode of inquiry approach to our data collection and analysis, drawing on complexity thinking (Davis & Sumara, 2006) to bring our multiple points of view together as diversely positioned educators. Within our individual sites, each author has collected data as a part of longer-term research projects. In this paper presentation we compare and contrast these data sets, attending to significant intersections and juxtaposing issues of culture and globalization. Within this mode of inquiry we value the particularity of the individual contexts, and locate them alongside one another in a larger bricolage (Johnson, 2010).
We examined observational data, documents and artifacts using Freebody and Luke's (1990) four resources model and the further adaptions of this model (see e.g. Luke & Freebody, 1999) to understand how touch screen devices are being used and positioned as literacy tools. We have engaged in collaborative data analysis, often working 'together' using digital tools ourselves to enable collective conversations. For example, we have used Facetime on iPads and laptops, Skype and email to facilitate collective analyses. We applied iterative and recursive analyses to uncover reoccurring themes both within and across sites and artifacts.
As our paper will elaborate, mobile touch screen devices such as iPads are widely being taken up in educational settings, and regarded as having the possibility to shift teaching and learning in new directions, as "paradigm breakers" (p. 4, Gov't of AB, 2011). As personal, mobile devices, these tools present challenges that require educators to think differently about learning and teaching. Our paper also addresses the opportunities and affordances that iPads might offer to learners, as having the potential for students to engage in playful exploration, and in the role of designers, creators, and producers, rather than as passive recipients.

Two Essays on the economics of Education

We develop a job-market signaling model where signals may convey two pieces of information. This model is employed to study the GED exam and countersignaling (signals non-monotonic in ability). A result of the model is that countersignaling is more expected to occur in jobs that require a combination of skills that differs from the combination used in the schooling process. The model also produces testable implications consistent with evidence on the GED: (i) it signals both high cognitive and low non-cognitive skills and (ii) it does not affect wages. Additionally, it suggests modifications that would make the GED a more effective signal.

Esta pesquisa pretendeu investigar possíveis articulações, dos alunos no curso de graduação em administração, entre a idealização do papel de futuro profissional, a dinâmica da classe e a demanda do mercado de trabalho contemporâneo. Os sujeitos foram 50 (cinqüenta) alunos da disciplina de Psicologia no segundo semestre do curso de administração e seus professores. Centramos esta investigação em entrevistas com alunos, observação da dinâmica interacional presente na classe, devolutiva do processo grupal em seminário com alunos, análise dos exames finais; aplicação de questionários a professores; levantamento bibliográfico dos teóricos da administração na área de relacionamento interpessoal. Perguntamo-nos: como alunos, professores e teóricos definem o administrador competente? Que estratégias facilitam a formação das competências necessárias para o administrador contemporâneo? Quais seriam as possíveis estratégias facilitadoras para a formação dessas competências na graduação?

Uma análise da concorrência no setor brasileiro de celulose

Este trabalho analisa o setor brasileiro de celulose e tenta responder a duas questões principais: a abrangência do mercado relevante e a existência de poder de mercado das empresas que atuam neste setor. A dimensão produto do mercado relevante foi definida a partir de dados qualitativos. Devido à indisponibilidade de dados para uma análise qualitativa mais apurada, a opção foi pela celulose de fibra curta de eucalipto, produto mais importante do setor, tanto pela posição brasileira em tecnologia como pela pauta de exportações. Já quanto à dimensão geográfica, o procedimento realizado baseou-se em Forni (2004) que utiliza testes de raiz unitária para a definição do mercado. Concluiu-se que, com os dados disponíveis, o mercado deste produto pode ser considerado como internacional, não somente pelo resultado do teste como também pelo modo de funcionamento deste mercado. Definido o mercado de produto e geográfico, realizou-se um teste de poder de mercado, pois neste nicho, a Aracruz é líder mundial. Tal teste foi realizado com base na demanda residual descrita por Mayo, Kaserman e Kahai (1996) e estimado segundo Motta (2004). Concluiu-se que, apesar de a Aracruz possuir um elevado market share no setor, ela não possui poder de mercado.

Initial analysis from a Lidar observation campaign of sugar cane fires in the central and western portion of the S̃ao Paulo State - Brazil

The central and western portion of the S̃ao Paulo State has large areas of sugar cane plantations, and due to the growing demand for biofuels, the production is increasing every year. During the harvest period some plantation areas are burnt a few hours before the manual cutting, causing significant quantities of biomass burning aerosol to be injected into the atmosphere. During August 2010, a field campaign has been carried out in Ourinhos, situated in the south-western region of S̃ao Paulo State. A 2-channel Raman Lidar system and two meteorological S-Band Doppler Radars are used to indentify and quantify the biomass burning plumes. In addiction, CALIPSO Satellite observations were used to compare the aerosol optical properties detected in that region with those retrieved by Raman Lidar system. Although the campaign yielded 30 days of measurements, this paper will be focusing only one case study, when aerosols released from nearby sugar cane fires were detected by the Lidar system during a CALIPSO overpass. The meteorological radar, installed in Bauru, approximately 110 km northeast from the experimental site, had recorded echoes (dense smoke comprising aerosols) from several fires occurring close to the Raman Lidar system, which also detected an intense load of aerosol in the atmosphere. HYSPLIT model forward trajectories presented a strong indication that both instruments have measured the same air masss parcels, corroborated with the Lidar Ratio values from the 532 nm elastic and 607 nm Raman N2 channel analyses and data retrieved from CALIPSO have indicated the predominance of aerosol from biomass burning sources. © 2011 SPIE.

Conformidade ergonômica dos controles no posto de trabalho do operador de trator: estudo de caso NH 7630

This article discusses an ergonomic analysis of the controls used by tractor operators, covering their positions in relation to the casing of your job. Was performed an assessment of the controls of the job of a model NH 7630 tractor average power of 74 kW (100 CV), using the norms of the ABNT. With this screening could detect the positive and negative. Then was accomplished an analytical study of the controls. Evaluation results show that some controls of tractors have errors evaluated in relation to NBR/ ISO 6682.

Arbeitsbezogene Ressourcen, Stressoren und Beanspruchung bei klinischen und nicht-klinischen Personen

Trotz einer zunehmenden Relevanz psychischer Erkrankungen im Gesundheitssystem und einer bedeutenden psychosozialen Funktion der Arbeit gibt es bisher wenige Studien, die sich explizit einer Untersuchung des Zusammenhangs von psychischer Erkrankung und Arbeitsplatzproblemen widmen. Noch weniger Befunde gibt es zu einem Vergleich von klinischen und nicht-klinischen Personen bezüglich arbeitsrelevanter Faktoren. In der hier vorliegenden Studie erfolgte erstmals eine Überprüfung der Karasek-Modelle gleichzeitig an klinischen und nicht-klinischen Personen. Insgesamt nahmen 160 Personen an der Studie teil, jeweils 40 befanden sich in stationärer bzw. ambulanter psychotherapeutischer Behandlung; zu all diesen Personen wurden insgesamt 80 nicht-klinische Personen untersucht, die der Patientenstichprobe in Beruf, Geschlecht und Alter glichen. Alle Personen gaben Auskunft per Fragebogen und berichteten in einem etwa einstündigen Interview von Stressoren und Ressourcen am Arbeitsplatz. Diese Untersuchung ergab, dass sich die Arbeitsplatzprobleme klinischer Personen in der Qualität nicht von denen nicht-klinischer Personen unterschieden, jedoch berichteten klinische Personen eine höhere Anzahl an Arbeitsplatzproblemen. Die positiven Faktoren am Arbeitsplatz unterschieden sich weder qualitativ noch quantitativ zwischen klinischen und nicht-klinischen Personen. Die klinischen Personen setzten häufiger ungünstige Stressverarbeitungsstrategien ein und zeigten teilweise einen ungünstigeren Umgang mit der Arbeit. In der Gesamtstichprobe gelang eine Bestätigung des Job-Demand-Control-Modells sowie des Job-Demand-Control-Support-Modells (ohne Interaktionseffekte); Personen mit geringer Kontrolle, hohen Anforderungen und geringer sozialer Unterstützung am Arbeitsplatz wiesen die höchsten Erschöpfungswerte auf (38.8% der Varianz der Erschöpfungswerte konnte so erklärt werden). Innerhalb der klinischen Stichprobe und bei Personen mit hoher Internalität erbrachten die Modelle höhere Vorhersageleistungen, mögliche Ursachen werden diskutiert. Die Ergebnisse dieser Arbeit gehen über bisherige Befunde hinaus. Sie unterstreichen die Wichtigkeit der Berücksichtigung arbeitsrelevanter Faktoren in der Psychotherapie und unterstützen die aktuelle Entwicklung der zunehmenden gesundheitsrelevanten Hilfsangebote für Arbeitnehmer (z.B. Coaching-Sitzungen) in großen Unternehmen.
