Padrão temporal de exposição ao ciclo claro/escuro natural e expressão dos cronotipos em uma região rural. / Temporal pattern of exposure to natural light/ dark cycle and expression of morningness/eveningness tendencies in a rural area.Flávio Augustino Back 07 May 2008 (has links)
Sabemos que a expressão dos cronotipos resulta de influências genéticas e ambientais. Existem evidências na literatura que nos permitem supor a participação do padrão temporal de exposição ao ciclo claro/escuro natural no estabelecimento dos cronotipos. Neste estudo nosso objetivo principal foi comparar a distribuição de cronotipos de dois grupos que vivem na mesma região rural, mas que apresentam padrões temporais de exposição ao ciclo claro/escuro muito distintos. Ao mesmo tempo, avaliamos a satisfação dos voluntários com seus horários de início de trabalho. Para isso estudamos dois grupos: Grupo de Trabalhadores em Ambiente Aberto (GTAA) e Grupo de Trabalhadores em Ambiente Fechado (GTAF). O GTAA foi composto por 29 voluntários com idade média de 30,8 ± 10,0 anos, enquanto o GTAF foi composto por 20 voluntários com idade média de 30,8 ± 9,8 anos. Aplicamos o questionário de matutinidade e vespertinidade e um questionário sobre os horários de trabalho para todos os voluntários, na maioria das vezes, em suas casas. Medidas das intensidades luminosas dos ambientes de trabalho dos voluntários foram coletadas. Comparamos a pontuação do questionário de cronotipos e a diferença entre o horário em que os voluntários trabalham e o horário em que gostariam de trabalhar entre os dois grupos. Usamos o teste estatístico de Kruskal-Wallis para essas comparações. Fizemos também uma regressão linear entre a pontuação do questionário de matutinidade e vespertinidade e a idade dos voluntários, um coeficiente de correlação foi obtido. Sugerimos com nossos resultados que o contexto fótico associado às naturezas espacial e temporal da ocupação laboral (contexto não-fótico) dos indivíduos pode modular a expressão dos cronotipos. Devido ao contexto fótico associado ao contexto não-fótico dos voluntários, o GTAA parece se ajustar melhor aos seus horários diurnos de trabalho. Finalmente, discutiremos neste trabalho a importância de se contextualizar socialmente a sincronização fótica de humanos para se estudar a expressão dos cronotipos. / It is known that the expression of the chronotypes results from both genetic and environmental influences. There are evidences in the literature which allow us to believe in the participation of the temporal pattern of exposition to the natural light/dark cycle in the establishment of the morningness/eveningness tendencies. In this study, our specific goal was to compare the distribution of the chronotypes in two groups of people sharing the same rural region for living, but with very different temporal patterns of exposition to the light/dark cycle. We also evaluated the satisfaction of the volunteers with their work schedule. Two groups were studied: Indoor Environment Group of workers (IEG) and Outdoor Environment Group (OEG) of workers. The OEG comprised 29 volunteers with average age of 30.8 ± 10.0 years old and the IEG 20 volunteers with average age of 30.8 ± 9.8 years old. We applied the Morningness-Eveningness Questionnaire and other questionnaire about the working time for all volunteers, most of times, in their homes. Measures of the light intensity of the volunteers\' working places were collected. We compared the scores of the questionnaire of chronotypes and the difference between the time in which the volunteers work and the time in which they would like to work, between the two groups. We used the statistic test of Kruskal-Wallis for these comparisons. We also applied a linear regression model between the score of the morningness-eveningness questionnaire and the age of the volunteers, obtaining a correlation coefficient. We suggest with our results that the photic context associated with the spacial and temporal natures of the working occupation, non-photic context, may modulate the expression of peoples\' chronotypes. Because of the photic context associated to the non-photic context of the volunteers, the OEG seems to have a better adjustment to the morning shift. Finaly, we discuss the importance of taking social context in consideration in studies of photic synchronization of humans.

Employee worktime control and healthAla-Mursula, L. (Leena) 25 October 2006 (has links)
Abstract
The potential health effects of employee control over working times are poorly known in the field of work stress research. In this study, worktime control was hypothesized to buffer against stress by promoting successful combination of a full-time job with non-work demands and by enabling the work to be done at times of optimal resources.
The participants were from the 10-Town Study, an ongoing longitudinal cohort study exploring employee health in ten Finnish towns. The survey responses on worktime control and health (baseline survey in 1997: n = 6442, 67%; follow-up survey in 2000–01: n = 32299, 67%) were linked to registered sickness absences from the employers' records. Employee worktime control covered the perceived possibilities to influence the starting and ending times of a workday, the breaks, handling private matters during the workday, the scheduling of shifts, vacations and days off, and the taking of unpaid leaves, each of which was rated on a 1–5 scale. In the follow-up survey, influence on the length of the workday was also assessed. After a factor analysis, the subdimensions of control over daily working hours and control over days off were focused.
It turned out that low worktime control predicted poor subjective health, psychological distress, and medically certified sickness absences for women. For men, low worktime control was not associated with subjective health, but predicted medically certified sickness absences for those with dependent children or employed in manual occupations.
With respect to work stress, the men and women suffering from job strain or effort-reward imbalance had less medically certified sickness absences if they at least had control over their working times.
The men and women with long domestic and total working hours and long commuting hours gained most from high worktime control in that their medically certified sickness absences were reduced. Vulnerability to long domestic and total working hours in terms of such absences was seen among both men and women, but there were few men working long domestic hours. Long paid working hours as such were not associated with sickness absences.
In sum, high worktime control appeared to buffer against health problems and to promote a successful integration of domestic responsibilities with a full-time job. The findings expand the focus of work stress research and emphasize the importance of taking conditions at home into account when analysing employee health. / Tiivistelmä
Työaikojen hallinnan merkitys terveydelle tunnetaan työstressitutkimuksen alalla huonosti. Tässä väitöskirjatyössä oletettiin, että työaikojen hallinta voisi vähentää stressiä ja edistää terveyttä helpottamalla kokopäivätyön ja kotona tehtävän työn yhteensovittamista sekä mahdollistamalla työn tekemisen parhaiden voimavarojen vallitessa.
Tutkimus toteutui osana Työterveyslaitoksen Kunta10 -tutkimusta, joka seuraa kymmenen suomalaisen kaupungin henkilöstön työolojen ja terveyden kehittymistä. Koettua työaikojen hallintaa ja terveyttä koskevat kyselyvastaukset (alkukysely v. 1997: n = 6442, 67 %; seurantakysely vv. 2000–01: n = 32299, 67 %) linkitettiin palkanmaksurekistereistä saatuihin sairauspoissaolotietoihin. Työaikojen hallinnan mittari sisälsi alkukyselyssä 5-luokkaisella asteikolla vastaajien kokemat vaikutusmahdollisuudet työpäivän alkamis- ja päättymisajankohtiin, taukoihin, yksityisasioiden hoitamiseen työpäivän kuluessa, työvuoroihin, lomien ja vapaapäivien ajankohtiin sekä palkattomien vapaiden pitämiseen. Seurantakyselyssä kartoitettiin myös vaikutusmahdollisuudet työpäivän pituuteen. Summamuuttujan faktorianalyysin jälkeen arvioitiin erikseen päivittäisten työaikojen hallintaa sekä loma-aikojen hallintaa.
Tuloksissa huono työaikojen hallinta ennusti naisilla huonoksi koettua terveyttä, psyykkistä rasittuneisuutta sekä lääkärintodistusta vaativia yli kolmen päivän mittaisia sairauspoissaoloja. Miehillä huono työaikojen hallinta ei vaikuttanut itsearvioituun terveyteen, mutta ennusti lääkärintodistusta vaativia sairauspoissaoloja, jos heillä oli lapsia kotona tai jos he tekivät ruumiillista työtä.
Hyvä työaikojen hallinta vähensi työstressiin liittyviä sairauspoissaoloja. Stressiä kuvattiin työn kovien vaatimusten ja huonon hallinnan yhdistelmällä sekä koettujen ponnistelujen ja palkkioiden epäsuhdalla.
Eri elämänalueilla tehtyihin työtunteihin suhteutettuna hyvä työaikojen hallinta vähensi sairauspoissaoloja erityisesti niillä naisilla ja miehillä, joilla oli paljon kotityötunteja, työmatkatunteja tai totaalityötunteja. Sairauspoissaoloilla mitattuna naiset ja miehet olivat yhtä haavoittuvia pitkille kotityö- työmatka- ja totaalityötunneille, mutta miehillä pitkät kotityötunnit olivat harvinaisia. Pitkät palkkatyötunnit sinänsä eivät lisänneet sairauslomia.
Tutkimus tuo työstressikirjallisuuteen vallitsevia malleja täydentävää tietoa työn ulkopuolisten tekijöiden merkityksestä työntekijöiden terveydelle. Tulokset kannustavat edistämään työntekijöiden mahdollisuuksia työaikojensa hallintaan sekä terveyden edistämisen että kokopäivätyön ja muun elämän menestyksellisen yhdistämisen näkökulmista.

Integration of knowledge of systematics in the teaching of population studies and biodiversity to grade 11 Life Sciences learnersMorrison, Eddie Michael 17 May 2011 (has links)
The implementation of the National Curriculum Statement in 2006 saw the name of the subject known as Biology change to Life Sciences accompanied by changes in subject content. The curriculum committee excluded systematics as a separate unit from the new outcomes-based Life Sciences curriculum for grades 10 to 12 that was implemented in 2006. Educators had to include aspects of systematics in teaching these concepts without guidance from the curriculum. This posed the question whether mastery of population dynamics and biodiversity is dependent on content of systematics in the context of the new curriculum. The New Content Framework for Life Sciences implemented in 2009 reintroduced systematics as a single unit. This raised the question why systematics has been reintroduced in the Life Sciences curriculum. This study aims to determine the influence the exclusion of systematics as a separate unit from the Life Sciences curriculum, implemented in 2006, had on the teaching of population studies and biodiversity. Data was gathered by evaluating and analysing the relevant curriculum statements, work schedules and content frameworks. Semi-structured interviews were conducted, first in 2008 when systematics was excluded from the curriculum and then in 2009 after the reintroduction. The first interviews dealt with the exclusion of systematics and the second interviews queried the reintroduction of systematics in the New Content Framework. Interviews were conducted with grade 11 Life Sciences educators at two secondary schools and two curriculum developers involved in compiling the Life Sciences curriculum. An expert in systematics and another in ecology were interviewed about the exclusion of systematics. The workbooks of some grade 11 learners were studied. Classroom observations were conducted when the relevant topics were being covered in class. A number of reasons for the exclusion of systematics from the NCS were advanced. These included: there was no population dynamics expert in the curriculum development team, emphasis was placed on outcomes and not content, the academic background of the members of the curriculum team and the difficulty of teaching systematics, perceived to be uninteresting. There was disagreement whether systematics is essential for understanding population dynamics but there is consensus that the study of systematics influences biodiversity and its exclusion left a regrettable void. However, systematics should be taught in a more interesting way. Prior knowledge is important for understanding of certain processes and concepts as well as for the application of practical skills like problem-solving and scientific inquiry. The curriculum does not provide detailed guidance on the content and practical activities to be covered and educators are encouraged to develop their own curriculum and activities. Experienced educators with strong academic backgrounds in animal and plant sciences referred to or used knowledge of systematics in some lessons. In 2009, systematics was reintroduced in the Life Sciences curriculum to ensure that learners understand biodiversity and evolution through natural selection. It provides learners a better foundation to understand similarities and differences in the structure and function of different organisms and body plans and ensures that they use higher-order thinking skills when doing problem-solving and scientific inquiry activities. / Dissertation (MEd)--University of Pretoria, 2010. / Curriculum Studies / unrestricted

Previous issue date: 2014 / Resumo: O presente trabalho partiu do questionamento sobre a tendência temporal e ecológica das morbidades mentais entre metalúrgicos e trabalhadores da educação. Investigamos o possível relacionamento dessas tendências com as mudanças que intensificaram o processo de trabalho em dois setores de atividade econômica muito diferentes. Esta tese combinou método de estudo de caso do setor metalúrgico com estudo ecológico nacional sobre trabalhadores da metalurgia e da educação. Realizamos o estudo de caso com observação direta e entrevistas no ambiente de trabalho sucedida por estudo documental histórico sobre empresa metalúrgica transnacional utilizando fontes públicas oficiais: _ Ministério do Trabalho e Emprego ¿ MTe, Ministério Público do Estado de São Paulo ¿ MP e o Ministério Público do Trabalho ¿ MPT. Numa segunda etapa os trabalhadores da educação foram comparados com metalúrgicos em estudo ecológico que usou bases nacionais brasileiras de dados sobre benefícios do Instituto Nacional de Seguridade Social ¿ INSS. Os desfechos epidemiológicos foram diagnósticos concedidos no Brasil aos trabalhadores para Licenças do Trabalho para tratamento de Saúde ¿ LTS e as exposições estudadas foram as categorias econômicas classificadas na Classificação Nacional de Atividades Econômicas ¿ CNAE, versão 2.0, para período de doze anos entre 2000-2011. O primeiro artigo abordou riscos psicossociais decorrentes da introdução de um novo modelo de gestão, o Lean Production, em uma indústria metalúrgica. O Lean passou a ser objeto de observação do trabalho de campo realizado no ano de 1996, quando a empresa passava por processo de fusão e internacionalização. Foram feitas entrevistas chave de trabalhadores e gerentes, complementadas posteriormente com análise documental. Anos depois, entre 2004 e 2009 voltamos a estudar a empresa, refazendo entrevistas a sindicatos e analisando processo judicial no MPT que lhe atribuía más condições trabalhistas, riscos à saúde e ao xx ambiente do trabalho. Essa metodologia criou oportunidade inédita de confrontar observação direta com resultantes posteriores sobre o trabalho e a saúde dos trabalhadores. O questionamento fundamental foi sobre relações entre o modelo de gestão - lean-production - e sua possível associação com riscos psicossociais à saúde dos trabalhadores. Constatamos nos processos judiciais que aquela multinacional de autopeças foi questionada pelo uso de jornadas excessivas com horas extras de trabalho, trabalho sem descanso semanal e jornadas com duração acima de dez horas. Essas condições de trabalho foram consideradas pelo MTe, MP e MPT como fontes de riscos psicossociais associados com afastamentos relacionados a adoecimento pelo trabalho. Os artigos Dois e Três analisamos adoecimentos de trabalhadores no setor da metalurgia no Brasil no período de 2000 a 2011. Nestes artigos descrevemos as doenças às quais foram atribuídas as LTS analisando fontes brasileiras de dados para todo o mercado formal de trabalho (celetista) no país. Os numeradores foram extraídos dos diagnósticos que motivaram as LTS classificados pela Classificação Internacional de Doenças (CID10) no Sistema Único de Benefícios (SUB) do INSS. Os denominadores foram retirados da GFIP ¿ Guia de Recolhimento do Fundo de Garantia por tempo de Serviço (FGTS) e de Informações à Previdência Social cobrindo doze anos no período 2000 a 2011. Estes artigos apresentam estudo ecológico descritivo sobre uma coorte nacional dinâmica não concorrente dos trabalhadores de cada setor da economia formal e traçaram as tendências das doenças mais prevalentes (artigo 2), detalhando posteriormente a comparação entre as incidências de LTS por doenças mentais e cardiovasculares entre os trabalhadores das duas categorias de atividades econômicas (artigo 3). O artigo 2 descreve as causas principais de LTS. As lesões externas foram a principal causa de afastamentos entre trabalhadores da metalurgia ¿ variando de 125,4 a 221,6 por 10.000 trabalhadores com vínculo celetista. A segunda causa foram os distúrbios musculoesqueléticos com 85,5 a 207.1 benefícios por 10.000 xxi trabalhadores. Seguiram-se os transtornos mentais com 19,8 a 58,8 / 10.000 na metalurgia e 11,5 a 38,9 / 10.000 entre os trabalhadores da educação. O câncer apareceu como a única categoria de doenças com incidência mais alta de LTS entre os trabalhadores da educação comparados aos da metalurgia. Os transtornos mentais atingiram mais os metalúrgicos que aos trabalhadores do ensino. Esse foi o achado mais importante e reforçou a hipótese de que o `Lean Production¿ trouxe estressores aos ambientes de trabalho e contribuiu para aumentar os adoecimentos e trazer os metalúrgicos a um nível de adoecimento psíquico mais elevado que o dos trabalhadores da educação. Estudamos no artigo 3 os adoecimentos mentais e cardiovasculares entre trabalhadores da educação e metalúrgicos. A força de trabalho média anual da metalurgia variou entre 268.759 e 468.613 no período de 2000 a 2011. Um total de 19.722 trabalhadores sofreram afastamento por transtornos mentais e 10.787 tiraram LTS por doenças do aparelho circulatório. Entre os transtornos mentais predominaram os transtornos do humor com curvas de afastamento superiores para os trabalhadores da metalurgia com pico de 29,2 comparados a 25,7 / 10.000 entre trabalhadores da educação em 2006. Os transtornos mentais por abuso de substâncias psicoativas apresentam tendência de elevação mais importante entre os trabalhadores da metalurgia (15,9 v.g. 2,4 / 10.000 em 2011). Também os transtornos neuróticos relacionados com o stress predominam entre os metalúrgicos até 2008 (11,0 v.g. 9,2 / 10.000). Entre as doenças do aparelho circulatório predominaram as doenças das veias e linfáticos principalmente entre trabalhadores da metalurgia (19,1 v.g. 8,7 / 10.000). As doenças hipertensivas predominaram entre trabalhadores do ensino com picos de 6,5 / 10.000 em 2002 e 2004 comparados a 4,5 / 10.000 entre metalúrgicos em 2005 com tendência decrescente até 1,4 e 1,0 respectivamente em 2011. As doenças isquêmicas do coração flutuam entre valores próximos de 2,5 e 4,1 por 10.000 trabalhadores, sendo que a curva em geral é mais elevada para os trabalhadores da metalurgia e ambas categorias apresentaram tendências de queda a partir de 2008 / Abstract: The present research departed from questioning the time trends and the ecology of mental morbidities amongst workers in metallurgy and education. We investigated the possible relationships of those trends with the increased work process intensity, which changed these two sectors of the economy with so different settings. This thesis combined the method of a case study in the metallurgy sector with a national ecologic study on workers of metallurgy and education. We conducted the case study with direct observation and interviews at the work environment followed by a historic and documental study on a transnational metallurgical company using official public records from the: _ National Department of Labor and Employment ¿ MTe, São Paulo State Department of Public Attorneys ¿ MP and the Federal Department of Labor Public Attorneys ¿ MPT. In a second step, we compared education workers with metallurgists in an ecologic design that used Brazilian national databases of workers¿ compensations from the National Institute of Social Security ¿ INSS. The epidemiologic outcome was the diagnosed morbidity recorded in Brazil when workers claimed sick leaves ¿ LTS and the exposure studied was presumed to working in the economic sectors classified according the National Classification of Economic Activities ¿ CNAE, version 2.0, for the twelve years period of 2000-2011. The first article addressed psychosocial risks arising from the introduction of the de Lean Production method in a metallurgic industry. This method combined a field observation conducted in the year 1996 with key interviews of workers and managers. It was complementary added to a historical documental analysis long afterwards the moment of the field observation when the company was undergoing the merging and internationalization process. Years later, from 2000 through 2009, we analyzed the litigation process put by the MPT that attributed to the company the responsibility for bad working conditions, with risks to workers¿ health and work xxvi environment. This methodology created the unprecedented opportunity of confronting results from direct observation with late results on workers¿ health and work environment inspection. Our fundamental question was on the relationships between the managing model of - lean-production and its possible association with psychosocial risks at work. We found that the multinational auto parts company was sued after using excessive journeys with long extra working hours, the lack of weekly days of resting, and work journeys longer than then hours a day. The MTe, MP and the MPT considered these working conditions as a source of psychosocial risks associated with sick leaves and working related morbidity. Articles 2 and 3 described the diseases to which sick leaves (LTS) were attributed after analyzing the Brazilian database sources for the total of the national formal labor market in the country. Numerators were taken from the diagnosed morbidity classified according to the International Classification of Diseases - (ICD10 /CID10) that were considered the reasons for the LTS at the National Unified Compensations¿ System (SUB) of the INSS. Denominators came from the GFIP ¿ a database that combined the Tax Report Form of the Worker¿s Savings Fund of Working Time (FGTS) together with the Labor Force Reports to the Department of National Social Security that covered a twelve years period from 2000 to 2011. These two articles reported a descriptive ecologic study on a national dynamic and non-concurrent cohort of workers in each sector of the formal economy. They traced the twelve years trend of the most prevalent diseases (article 2), detailing at last the comparison between the LTS incidences due to mental and cardiovascular diseases among workers of the two categories of economic activity (article 3). Article 2 describes main causes for LTS. External causes were the most incident reasons for sick leaves among metalworkers ¿ varying from 125.4 to 221.6 by 10,000 formally registered jobs. The second group were musculoskeletal disorders with 85.5 to 207.1 LTS for 10,000 workers. Mental disorders followed in both sectors with 19.8 to 58.8 / 10,000 in metallurgy and 11.5 to 38.9 / 10,000 among xxvii education workers. Cancer appeared as the only disease group¿s category with high LTS incidence among educators compared to metalworkers. Mental disorders affected more metalworkers than those in education. This was the most important finding that reinforced the hypothesis that the `Lean Production¿ method brought more stressors to the work environment and contributed to increase morbidity of metalworkers to levels of mental disorders above those in the educational economic sector. Article 3 studied the LTS due to mental and cardiovascular diseases comparing educational and metalworkers. The yearly mean employed work force in metallurgy varied from 268,759 to 468,613 job places in the period 2000 through 2011. About 19,722 metalworkers took LTS due to mental disorders and 10,787 were affected by circulatory disorders. Mental disorders were mostly specified as affective and mood disorders with sick leaves¿ trends of metallurgy well above with peaks of 29.2 compared to 25.7 / 10,000 among education workers in 2006. Mental disorders due to psychoactive drugs¿ abuse (F10- F19) showed an increasing trend more important among metalworkers (15.9 vs. 2.4 / 10,000 in 2011). Stress related neurotic disorders were also predominant among metalworkers until 2008 (11.0 vs. 9.2 / 10,000). Diseases of lymphatic vessels and veins were the main causes of LTS in the cardiovascular diseases¿ group especially among metalworkers (19.1 vs. 8.7 / 10,000). Hypertensive diseases predominate among education workers with peaks of 6.5 / 10,000 in 2002 and 2004 compared to 4.5 / 10,000 among metalworkers in 2005 both with a decreasing trend until 1.4 and 1.0 respectively in 2011. Ischemic heart diseases drifted among figures close to 2.5 and 4.1 / 10,000 workers with the metalworkers running always above despite both economic sectors showed a noticeable decrease from 2008 on. Our conclusions were discrepant from the preliminary hypothesis that supposed to find greater psychic risks among education workers once metalworkers would expose themselves mostly to physical workloads with a consequence of higher xxviii incidence of musculoskeletal diseases in LTS. The analysis of both ecologic studies turned this forecast down. The main finding of this research was that metalworkers showed increasing trends of LTS incidence by prevalent morbidity above those found among education workers of the education economic sector due to affective and mood disorders, as well as mental disorders due to psychoactive drugs¿ abuse, the somatoform and stress related neurotic disorders. The twelve years period under analysis showed a trend of increasing the incidence of LTS in both groups of economic activity with the exception of cardiovascular diseases.

Le rôle des horaires atypiques, du conflit travail-famille, de l’autorité décisionnelle et des demandes psychologiques sur la santé mentale des travailleurs au CanadaDalexis, Rose D. 08 1900 (has links)
Les transformations du monde du travail, dues à la mondialisation, se font principalement au profit de l’efficacité et l’efficience des entreprises. Ces changements, touchant aussi l’organisation du travail, ne sont pas sans effets sur la santé des travailleurs. Cette étude traite principalement de l’effet des horaires atypiques sur la santé mentale des travailleurs. Elle a pour objectifs 1) d’étudier l’association entre l’horaire atypique et les problèmes de santé mentale chez les travailleurs ; 2) d’explorer l’effet du conflit travail-famille, des demandes psychologiques et de l’autorité décisionnelle sur la santé mentale des travailleurs. Cette étude est basée sur un échantillon de 2 162 participants de l’enquête SALVEO, qui est une des plus importantes études réalisées sur la santé mentale et le travail au Canada. Préalablement, des analyses descriptives ont été effectués afin de dresser le portrait de la population à l’étude et de comparer la prévalence des problèmes de santé mentale chez les travailleurs. Afin de tester les hypothèses, des analyses de corrélation bivariée et de régression logistique ont été réalisées. Les résultats nous ont montré que les horaires atypiques n’ont pas d’association directe sur la santé mentale des travailleurs. Cependant, l’horaire atypique est associé à des problèmes de santé mentale. Le conflit travail-famille et les demandes psychologiques tendent à augmenter le risque de développer des problèmes de santé mentale, et inversement pour l’autorité décisionnelle. / The changes in the world of work due to globalization are mainly for the benefit of the effectiveness and efficiency of enterprises. These changes, which also affect the work organization, are not without effects on the health of workers. This thesis focuses on the effect of non-standard work schedules on the mental health of workers. Its objectives are 1) to study the association between non-standard schedules and mental health problems among workers; and 2) to explore the effect of work-family conflict, psychological demands, and decision latitude on workers' mental health. This study is based on a sample of 2,162 participants from the SALVEO survey, which is one of the most important mental health studies conducted in Canada. Preliminary, descriptive analyses were conducted in order to draw up a portrait of the study population and compare the prevalence of mental health problems among workers. In order to refute or confirm the hypotheses put forward, bivariate correlation and logistic regression analyses were carried out. All analyses were performed using version 25 of the SPSS software. The results showed us that non-standard schedules have no direct effect on the mental health of workers. However, people working non-standard schedules are at greater risk of developing mental health problems compared to those working standard schedules. Work-family conflict and psychological demands tend to increase the risk of developing mental health problems, while decision-making latitude has the opposite effect.

Précarité d’emploi et défaillances du cadre juridique : exemple de l’industrie de la restaurationGingras, Sébastien 01 1900 (has links)
Dans ce mémoire, nous nous intéressons à la portée effective de la protection offerte par le droit du travail au Québec dans le contexte actuel du marché de l’emploi. Pour approfondir cette question, nous avons choisi d’explorer l’application du droit dans une industrie où les conditions de travail se révèlent bien souvent difficiles et contraignantes, voire carrément précaires. Ce mémoire traite de l’industrie de la restauration. Plus précisément, notre analyse porte sur les difficultés que pose, dans ce secteur d’activité, l’application des normes juridiques destinées à encadrer la relation employeur-salarié. Le présent ouvrage s’articule autour des facettes de l’industrie de la restauration à l’égard desquelles l’application de ces normes est susceptible de connaître des ratés, à savoir l’identification de l’employeur dans les franchises de restauration, le contrôle du salarié sur son horaire de travail, la sécurité d’emploi et l’accès à la syndicalisation.
Notre étude tend à démontrer que, dans leur forme actuelle, les lois du travail accentuent l’instabilité qui caractérise les conditions auxquelles sont soumis les salariés de l’industrie de la restauration. Ce mémoire met en lumière les raisons pour lesquelles la protection dont jouissent ces salariés se révèle dans bien des cas insuffisante. Bien qu’elle se cantonne à un seul secteur d’activité économique, la présente étude s’inscrit dans un phénomène global en ce que les problèmes qui y sont abordés affectent le marché du travail dans son ensemble. / This thesis focuses on the ability of Quebec labour laws to fully exert their protective role in the current context of the labour market. To explore this question in depth, we have chosen to analyze the application of the law in an industry where working conditions are often difficult and restrictive, even downright precarious, namely the restaurant industry. Specifically, this analysis focuses on the difficulties posed by the application of legal standards intended to regulate the employer-employee relationship. We look at the facets of the restaurant industry where the application of these standards is likely to fail, namely the identification of the real employer in restaurant franchises, the employee control over working hours, job security and access to unionization.
This study is meant to show that, in their current form, labour laws worsen the instability that characterizes the working conditions to which employees in the restaurant industry are subjected. This thesis sheds light on the reasons why the protection enjoyed by these employees is in many cases insufficient. Although it is confined to a single sector of economic activity, this study is part of a global phenomenon in the sense that the dynamics causing the difficult working conditions in the restaurant industry affect the whole labour market.
