Work and health : remodelling perspectives of working life research, as proposed by Järvholm et al. (2009)

Järvholm and Co-workers (2009) proposed a conceptual model for research on working life. Models are powerful communication and decision tools. This model is strongly unidirectional and does not cover the mentioned interactions in the arguments.With help of a genealogy of work and of health it is shown that work and health are interactive and have to be analysed on the background of society.Key words: research model, work, health, occupational health, society, interaction, discussion paperRemodellierung der von Järvholm et al. (2009) vorgeschlagenen Forschungsperspektiven in Arbeit und GesundheitJärvholm und Kollegen stellten 2009 ein konzeptionelles Modell für die Forschung im Bereich Arbeit und Gesundheit vor. Modelle stellen kraftvolle Kommunikations- und Entscheidungsinstrumente dar. Die Einflussfaktoren im Modell verlaufen jedoch nur in einer Richtung und bilden die interaktiven Argumente im Text nicht ab. Mit Hilfe einer Genealogie der Begriffe Arbeit und Gesundheit wird aufgezeigt, dass Arbeit und Gesundheit sich gegenseitig beeinflussen und nur vor dem Hintergrund der jeweiligen gesellschaftlichen Kontextfaktoren zu analysieren sind.Introduction : After an interesting introduction about the objectives of research on working life, Järvholm and Co-workers (2009) manage to define a conceptual model for working life research out of a small survey of Occupational Safety and Health (OSH) definitions. The strong point of their model is the entity 'working life' including personal development, as well as career paths and aging. Yet, the model Järvholm et al. (2009) propose is strangely unidirectional; the arrows point from the population to working life, from there to health and to disease, as well as to productivity and economic resources. The diagram only shows one feed-back loop: between economic resources and health. We all know that having a chronic disease condition influences work and working capacity. Economic resources have a strong influence on work, too. Having personal economic resources will influence the kind of work someone accepts and facilitate access to continuous professional education. A third observation is that society is not present in the model, although this is less the case in the arguments. In fact, there is an incomprehensible gap between the arguments brought forth by Järvholm and co-workers and their reductionist model.Switzerland has a very low coverage of occupational health specialists. Switzerland is a long way from fulfilling the WHO's recommendations on workers' access to OSH services as described in its Global plan of action. The Institute for Work and Health (IST) in Lausanne is the only organisation which covers the major domains of OSH research that are occupational medicine, occupational hygiene, ergonomic and psychosocial research. As the country's sole occupational health institution we are forced to reflect the objectives of working life research so as not to waste the scare resources available.I will set out below a much shortened genealogy of work and of health, with the aim of extending Järvholm et al's (2009) analyses on the perspectives of working life research in two directions. Firstly towards the interactive nature of work and health and the integration of society, and secondly towards the question of what working life means or where working life could be situated.Work, as we know it today - paid work regulated by a contract as the basis for sustaining life and as a base for social rights - was born in modern era. Therefore I will start my genealogy in the pre-modern era, focus on the important changes that occurred during industrial revolution and the modern era and end in 2010 taking into account the enormous transformations of the past 20-30 years. I will put aside some 810 years of advances in science and technology that have expanded the world's limits and human understanding, and restrict my genealogy to work and to health/body implicating also the societal realm.

Decreased well-being after job loss : testing omitted causes

Job loss is widely known to lead to a substantial decrease in workers' subjective well-being. Functionalist theories explain this fact by arguing that the fundamental needs that work fulfills are absent during unemployment. Recent evidence from longitudinal studies however contradicts this approach, showing that workers who find a new job do not fully regain their former level of well-being upon reemployment. Therefore other mechanisms must be at work. We suggest that changes in social or economic domains of workers' lives - triggered by job displacement - lead to the observed changes in well-being. Drawing on a unique data set from a survey of workers displaced by plant closure in Switzerland after the financial crisis of 2008, our analysis confirms the previous result that finding a job after displacement does not completely restore workers' pre-displacement level of well-being. The factors that best explain this outcome are changes in social domains, notably changes in workers' job - related social status and their relationships to friends. This result provides valuable insights about the long lasting scars job displacement leaves on workers' lives.

Hypoxie-ischémie cérébrale néonatale : rôle de la voie de JNK et implication de l'autophagie dans la mort neuronale

Résumé : Malgré les immenses progrès réalisés depuis plusieurs années en médecine obstétricale ainsi qu'en réanimation néonatale et en recherche expérimentale, l'asphyxie périnatale, une situation de manque d'oxygène autour du moment de la naissance, reste une cause majeure de mortalité et de morbidité neurologique à long terme chez l'enfant (retard mental, paralysie cérébrale, épilepsie, problèmes d'apprentissages) sans toutefois de traitement pharmacologique réel. La nécessité de développer de nouvelles stratégies thérapeutiques pour les complications de l'asphyxie périnatale est donc aujourd'hui encore essentielle. Le but général de ce travail est l'identification de nouvelles cibles thérapeutiques impliquées dans des mécanismes moléculaires pathologiques induits par l'hypoxie-ischémie (HI) dans le cerveau immature. Pour cela, le modèle d'asphyxie périnatale (proche du terme) le plus reconnu chez le rongeur a été développé (modèle de Rice et Vannucci). Il consiste en la ligature permanente d'une artère carotide commune (ischémie) chez le raton de 7 jours combinée à une période d'hypoxie à 8% d'oxygène. Il permet ainsi d'étudier les lésions de type hypoxique-ischémique dans différentes régions cérébrales dont le cortex, l'hippocampe, le striatum et le thalamus. La première partie de ce travail a abordé le rôle de deux voies de MAPK, JNK et p38, après HI néonatale chez le raton à l'aide de peptides inhibiteurs. Tout d'abord, nous avons démontré que D-JNKI1, un peptide inhibiteur de la voie de JNK présentant de fortes propriétés neuroprotectrices dans des modèles d'ischémie cérébrale adulte ainsi que chez le jeune raton, peut intervenir sur différentes voies de mort dont l'activation des calpaïnes (marqueur de la nécrose précoce), l'activation de la caspase-3 (marqueur de l'apoptose) et l'expression de LC3-II (marqueur de macroautophagie). Malgré ces effets positifs le traitement au D-JNKI1 ne modifie pas l'étendue de la lésion cérébrale. L'action limitée de D-JNKI1 peut s'expliquer par une implication modérée des JNKs (faiblement activées et principalement l'isotype JNK3) après HI néonatale sévère. Au contraire, l'inhibition de la voie de nNOS/p38 par le peptide DTAT-GESV permet une augmentation de 20% du volume du tissu sain à court et long terme. Le second projet a étudié les effets de l'HI néonatale sur l'autophagie neuronale. En effet, l'autophagie est un processus catabolique essentiel au bien-être de la cellule. Le type principal d'autophagie (« macroautophagie » , que nous appellerons par la suite « autophagie ») consiste en la séquestration d'éléments à dégrader (protéines ou organelles déficients) dans un compartiment spécialisé, l'autophagosome, qui fusionne avec un lysosome pour former un autolysosome où le contenu est dégradé par les hydrolases lysosomales. Depuis peu, l'excès ou la dérégulation de l'autoptiagie a pu être impliqué dans la mort cellulaire en certaines conditions de stress. Ce travail démontre que l'HI néonatale chez le raton active fortement le flux autophagique, c'est-à-dire augmente la formation des autophagosomes et des autolysosomes, dans les neurones en souffrance. De plus, la relation entre l'autophagie et l'apoptose varie selon la région cérébrale. En effet, alors que dans le cortex les neurones en voie de mort présentent des caractéristiques mixtes apoptotiques et autophagiques, ceux du CA3 sont essentiellement autophagiques et ceux du CA1 sont principalement apoptotiques. L'induction de l'autophagie après HI néonatale semble donc participer à la mort neuronale soit par l'enclenchement de l'apoptose soit comme mécanisme de mort en soi. Afin de comprendre la relation pouvant exister entre autophagie et apoptase un troisième projet a été réalisé sur des cultures primaires de neurones corticaux exposés à un stimulus apoptotique classique, la staurosporine (STS). Nous avons démontré que l'apoptose induite par la STS était précédée et accompagnée par une forte activation du flux autophagique neuronal. L'inhibition de l'autophagie de manière pharmacologique (3-MA) ou plus spécifiquement par ARNs d'interférence dirigés contre deux protéines autophagiques importantes (Atg7 et Atg5) a permis de mettre en évidence des rôles multiples de l'autophagie dans la mort neuronale. En effet, l'autophagie prend non seulement part à une voie de mort parallèle à l'apoptose pouvant être impliquée dans l'activation des calpaïnes, mais est également partiellement responsable de l'induction des voies apoptotiques (activation de la caspase-3 et translocation nucléaire d'AIF). En conclusion, ce travail a montré que l'inhibition de JNK par D-JNKI1 n'est pas un outil neuroprotecteur efficace pour diminuer la mort neuronale provoquée par l'asphyxie périnatalé sévère, et met en lumière deux autres voies thérapeutiques beaucoup plus prometteuses, l'inhibition de nNOS/p38 ou de l'autophagie. ABSTRACT : Despite enormous progress over the last«decades in obstetrical and neonatal medicine and experimental research, perinatal asphyxia, a situation of lack of oxygen around the time of the birth, remains a major cause of mortality and long term neurological morbidity in children (mental retardation, cerebral palsy, epilepsy, learning difficulties) without any effective treatment. It is therefore essential to develop new therapeutic strategies for the complications of perinatal asphyxia. The overall aim of this work was to identify new therapeutic targets involved in pathological molecular mechanisms induced by hypoxia-ischemia (HI) in the immature brain. For this purpose, the most relevant model of perinatal asphyxia (near term) in rodents has been developed (model of Rice and Vannucci). It consists in the permanent ligation of one common carotid artery (ischemia) in the 7-day-old rat combined with a period of hypoxia at 8% oxygen. This model allows the study of the hypoxic-ischemic lesion in different brain regions including the cortex, hippocampus, striatum and thalamus. The first part of this work addressed the role of two MAPK pathways (JNK and p38) after rat neonatal HI using inhibitory peptides. First, we demonstrated that D-JNKI1, a JNK peptide inhibitor presenting strong neuroprotective properties in models of cerebral ischemia in adult and young rats, could affect different cell death mechanisms including the activation of calpain (a marker of necrosis) and caspase-3 (a marker of apoptosis), and the expression of LC3-II (a marker of macroautophagy). Despite these positive effects, D-JNKI1 did not modify the extent of brain damage. The limited action of D-JNKI1 can be explained by the fact that JNKs were only moderately involved (weakly activated and principally the JNK3 isotype) after severe neonatal HI. In contrast, inhibition of nNOS/p38 by the peptide D-TAT-GESV increased the surviving tissue volume by around 20% at short and long term. The second project investigated the effects of neonatal HI on neuronal autophagy. Indeed, autophagy is a catabolic process essential to the well-being of the cell. The principal type of autophagy ("macroautophagy", that we shall henceforth call "autophagy") involves the sequestration of elements to be degraded (deficient proteins or organelles) in a specialized compartment, the autophagosome, which fuses with a lysosome to form an autolysosome where the content is degraded by lysosomal hydrolases. Recently, an excess or deregulation of autophagy has been implicated in cell death in some stress conditions. The present study demonstrated that rat neonatal HI highly enhanced autophagic flux, i.e. increased autophagosome and autolysosome formation, in stressed neurons. Moreover, the relationship between autophagy and apoptosis varies according to the brain region. Indeed, whereas dying neurons in the cortex exhibited mixed features of apoptosis and autophagy, those in CA3 were primarily autophagíc and those in CA1 were mainly apoptotic. The induction of autophagy after neonatal HI seems to participate in neuronal death either by triggering apoptosis or as a death mechanism per se. To understand the relationships that may exist between autophagy and apoptosis, a third project has been conducted using primary cortical neuronal cultures exposed to a classical apoptotic stimulus, staurosporine (STS). We demonstrated that STS-induced apoptosis was preceded and accompanied by a strong activation of neuronal autophagic flux. Inhibition of autophagy pharmacologically (3-MA) or more specifically by RNA interference directed against two important autophagic proteins (Atg7 and AtgS) showed multiple roles of autophagy in neuronal death. Indeed, autophagy was not only involved in a death pathway parallel to apoptosis possibly involved in the activation of calpains, but was also partially responsible for the induction of apoptotic pathways (caspase-3 activation and AIF nuclear translocation). In conclusion, this study showed that JNK inhibition by D-JNKI1 is not an effective neuroprotective tool for decreasing neuronal death following severe perinatal asphyxia, but highlighted two more promising therapeutic approaches, inhibition of the nNOSlp38 pathway or of autophagy.

Work motivation and pro-social behavior in the delivery of public services : theoretical and empirical insights

This Ph.D. dissertation seeks to study the work motivation of employees in the delivery of public services. The questioning on work motivation in public services in not new but it becomes central for governments which are now facing unprecedented public debts. The objective of this research is twofold : First, we want to see if the work motivation of employees in public services is a continuum (intrinsic and extrinsic motivations cannot coexist) or a bi-dimensional construct (intrinsic and extrinsic motivations coexist simultaneously). The research in public administration literature has focused on the concept of public service motivation, and considered motivation to be uni-dimensional (Perry and Hondeghem 2008). However, no study has yet tackled both types of motivation, the intrinsic and extrinsic ones, in the same time. This dissertation proposes, in Part I, a theoretical assessment and an empirical test of a global work motivational structure, by using a self-constructed Swiss dataset with employees from three public services, the education sector, the security sector and the public administrative services sector. Our findings suggest that work motivation in public services in not uni-dimensional but bi-dimensional, the intrinsic and extrinsic motivations coexist simultaneously and can be positively correlated (Amabile et al. 1994). Our findings show that intrinsic motivation is as important as extrinsic motivation, thus, the assumption that employees in public services are less attracted by extrinsic rewards is not confirmed for this sample. Other important finding concerns the public service motivation concept, which, as theoretically predicted, represents the major motivational dimension of employees in the delivery of public services. Second, the theory of public service motivation makes the assumption that employees in public services engage in activities that go beyond their self-interest, but never uses this construct as a determinant for their pro-social behavior. In the same time, several studies (Gregg et al. 2011 and Georgellis et al. 2011) bring evidence about the pro-social behavior of employees in public services. However, they do not identify which type of motivation is at the origin of this behavior, they only make the assumption of an intrinsically motivated behavior. We analyze the pro-social behavior of employees in public services and use the public service motivation as determinant of their pro-social behavior. We add other determinants highlighted by the theory of pro-social behavior (Bénabou and Tirole 2006), by Le Grand (2003) and by fit theories (Besley and Ghatak 2005). We test these determinants on Part II and identify for each sector of activity the positive or the negative impact on pro-social behavior of Swiss employees. Contrary to expectations, we find, for this sample, that both intrinsic and extrinsic factors have a positive impact on pro-social behavior, no crowding-out effect is identified in this sample. We confirm the hypothesis of Le Grand (2003) about the positive impact of the opportunity cost on pro-social behavior. Our results suggest a mix of action-oriented altruism and out-put oriented altruism of employees in public services. These results are relevant when designing incentives schemes for employees in the delivery of public services.

Subjective perceptions as prognostic factors of time to fitness for work during a 4-year period after inpatient rehabilitation for orthopaedic trauma.

INTRODUCTION: Time to fitness for work (TFW) was measured as the number of days that were paid as compensation for work disability during the 4 years after discharge from the rehabilitation clinic in a population of patients hospitalised for rehabilitation after orthopaedic trauma. The aim of this study was to test whether some psychological variables can be used as potential early prognostic factors of TFW. MATERIAL AND METHODS: A Cox proportional hazards model was used to estimate the associations between predictive variables and TFW. Predictors were global health, pain at hospitalisation and pain decrease during the stay (all continuous and standardised by subtracting the mean and dividing by two standard deviations), perceived severity of the trauma and expectation of a positive evolution (both binary variables). RESULTS: Full data were available for 807 inpatients (660 men, 147 women). TFW was positively associated with better perceived health (hazard ratio [HR] 1.16, 95% confidence interval [CI] 1.13-1.19), pain decrease (HR 1.46, 95% CI 1.30-1.64) and expectation of a positive evolution (HR 1.50, 95% CI 1.32-1.70) and negatively associated with pain at hospitalisation (HR 0.67, 95% CI 0.59-0.76) and high perceived severity (HR 0.72, 95% CI 0.61-0.85). DISCUSSION: The present results provide some evidence that work disability during a four-year period after rehabilitation may be predicted by prerehabilitation perceptions of general health, pain, injury severity, as well as positive expectation of evolution.

Relations of the job demands-control-support model of job strain with personality attributes : a cross-cultural study in Switzerland and South Africa

Among the various work stress models, one of the most popular to date is the job demands-­‐control (JDC) model developed by Karasek (1979), which postulates that work-­‐related strain will be the highest under work conditions characterized by high demands and low autonomy. The absence of social support at work will further increase negative outcomes. However, this model does not apply equally to all individuals and to all cultures. In the following studies, we assessed work characteristics, personality traits, culture-­‐driven individual attributes, and work-­‐related health outcomes, through the administration of questionnaires. The samples consist of Swiss (n = 622) and South African (n = 879) service-­‐oriented employees (from health, finance, education and commerce sectors) and aged from 18 to 65 years old. Results generally confirm the universal contribution of high psychological demands, low decision latitude and low supervisor support at work, as well as high neuroticism predict the worse health outcomes among employees in both countries. Furthermore, low neuroticism plays a moderating role between psychological demands and burnout, while high openness and high conscientiousness each play a moderating role between decision latitude and burnout in South Africa. Results also reveal that culture-­‐driven individual attributes play a role in both countries, but in a unique manner and according to the ethnic group of belonging. Given that organizations are increasingly characterized with multicultural employees as well as increasingly adverse and complex job conditions, our results help in identifying more updated and refined dynamics that are key between the employee and the work environment in today's context. -- L'un des modèles sur le stress au travail des plus répandus est celui développé par Karasek (1979), qui postule qu'une mauvaise santé chez les employés résulte d'une combinaison de demandes psychologiques élevées, d'une latitude décisionnelle faible et de l'absence de soutien social au travail. Néanmoins, ce modèle ne s'applique pas de façon équivalente chez tous les individus et dans toutes les cultures. Dans les études présentées, nous avons mesuré les caractéristiques de travail, les traits de personnalité, les traits culturels et les effets lies à la santé à l'aide de questionnaires. L'échantillon provient de la Suisse (n = 622) et de l'Afrique du Sud (n = 879) et comprend des employés de domaines divers en lien avec le service (notamment des secteurs de la santé, finance, éducation et commerce) tous âgés entre 18 et 65 ans. Les résultats confirment l'universalité des effets directs des demandes au travail, la latitude décisionnelle faible, le soutien social faible provenant du supérieur hiérarchique, ainsi que le névrosisme élevé qui contribuent à un niveau de santé faible au travail, et ce, dans les deux pays. De plus, un niveau faible de névrosisme a un effet de modération entre les demandes au travail et l'épuisement professionnel, alors que l'ouverture élevée et le caractère consciencieux élevé modèrent la relation entre la latitude décisionnelle et l'épuisement professionnel en Afrique du Sud. Nous avons aussi trouvé que les traits culturels jouent un rôle dans les deux pays, mais de façon unique et en fonction du groupe ethnique d'appartenance. Sachant que les organisations sont de plus en plus caractérisées par des employés d'origine ethnique variées, et que les conditions de travail se complexifient, nos résultats contribuent à mieux comprendre les dynamiques entre l'employé et l'environnement de travail contemporain. personnalité, différences individuelles, comparaisons culturelles, culture, stress au travail, épuisement professionnel, santé des employés.

Musculoskeletal disorders (MSD) are the most prevalent pain disorders in industrialized countries, and their costs can represent up to 2% of gross national product. MSD are often work associated and recurrent and may lead to disability. In occupational health we are interested in the opposite process : in the return to work (RTW). Different models of disability and RTW exist with different conceptions of psychosocial factors. We therefore propose to analyze the influence of factors from work, patient, health care providers, and broader societal domains along the different phases of the MSD process, adopting a biopsychosocial approach. The analysis of risk factors for the different phases of MSD indicate that work stress factors have an impact on the occurrence of MSD and RTW with MSD, but their effect is low to moderate and nonspecific. Physical work demands, work place adaptation, and pain experience are much stronger predictors of RTW. Lack of modified or adapted work is one of the major factors that hinder RTW. The longer the pain lasts, the longer the patient is out of work, the more personal factors and broader context factors become dominant. There is a clear lack of RTW studies concerning neck and upper limb pain. MSD and especially chronic MSD should be viewed as public health concerns, implying a wider socio-economic and insurance and disability problem. Adequate medical support tailored to the different dimensions and phases of MSD must be on offer, and work accommodations must be promoted and supported.

Plaisir et souffrance au travail : une lecture psychodynamique au sein d'un office régional de placement suisse

En Suisse, comme dans la plupart des pays industrialisés, le stress au travail et l'épuisement qui en découle sont devenus, au cours des dernières décennies, une réalité qui ne cesse de s'accentuer. Différentes disciplines scientifiques ont tenté de rendre compte, depuis le milieu du siècle dernier, des difficultés rencontrées par les individus dans le cadre de leur travail, avec une prédominance marquée pour des analyses de type causaliste. Dans le cadre de cette étude doctorale, nous nous sommes penché sur le cas d'un office régional de placement, mais avec une perspective sensiblement différente. La grille de lecture psychodynamique utilisée permet en effet de donner accès au sens des situations de travail et d'ouvrir sur une compréhension originale des mécanismes à l'origine des problèmes de santé mentale au travail. Cette approche permet ainsi de comprendre les rapports complexes que les individus entretiennent avec leur travail tel que structuré et organisé, et d'analyser leur expérience en termes de plaisir, de souffrance, de défenses face à la souffrance et de répercussions sur la santé. Dans ce but, nous avons utilisé une méthodologie basée sur des entrevues collectives, afin de stimuler l'expression libre des travailleurs. L'enquête s'est déroulée en deux temps : une première série d'entretiens de groupe a permis la récolte des données empiriques, puis une seconde série, appelée entretiens de restitution, a donné la possibilité aux participants de réagir sur l'interprétation de leur parole faite par le chercheur, et de valider l'analyse. Nos résultats mettent alors en évidence que le travail, tel qu'organisé au sein de cette institution de service public, apparaît considérablement pathogène, mais heureusement compensé par le pouvoir structurant de la relation d'aide aux assurés. Ils montrent également que l'expérience subjective de travail des participants a pour principales sources de souffrance la perception désagréable d'un manque de reconnaissance, d'autonomie et de pouvoir sur leurs actes. - In Switzerland and in other industrialized countries, work-related stress and resulting burn-out has become an ever increasing problem in recent decades. Many researchers Jrom many different fields have made efforts to understand the difficulties employees encounter at work since the middle of the last century. Most of this research is based on a cause and effect analysis approach. For this doctoral research project, we have analyzed cases handled by an unemployment office in Switzerland. We have taken a novel approach by using a number of psychodynamic criteria which permitted us to interpret situations at work and to open up a new way of understanding the mechanisms at work which lead to mental health problems. This approach allows us to understand account the complex relationship people have towards structured and organized work as well as to take into account and to analyze their experience in terms of pleasure, suffering, defense mechanisms against suffering and the consequences on their mental health. In order to achieve this goal we performed collective interviews in order to encourage workers to express themselves freely. The interviews were divided into two series. The first series of group interviews allowed us to collect empirical statistics and the second series gave the workers an opportunity to react to the researchers ' analysis of their answers and to validate the researchers ' interpretation of their answers. Our results show that work has considerable negative effects on mental health. Fortunately, these negative effects are counterbalanced by the psychological support system offered by the unemployment office. Our project also shows that the subjective negative experiences of workers are caused by their perceptions of being under-appreciated, lack of autonomy and having no power over their acts.

Patterns in the situated activity of substance use in the careers of elite doping athletes

Objectives This article presents a psychological approach to substance use in sport using a dynamic and situated activity framework. The aim was to analyze the various relationships between activity and the consumption of substances during the sporting life course of athletes who recognized doping violation. Design Data were collected from secondary sources and biographical and self-confrontational interviews to build traces of the past activity. Method Twelve doping athletes or those admitting to having used banned substances volunteered to participate. The data were coded and compared to identify typical activities and their intrinsic dynamics. Results Six activities were identified: "Agree to use," "Drop out of a non-viable state," Return to a former state," "Prevent a potential deficiency," "Maintain an acquired state," and "Balance the sporting life with substance use," comprising 11 patterns. Conclusions The athletes' activity embedded substance use in reciprocal relationships that consisted of freezing, exploring and exploiting fields of possible actions created and offered by the situation dynamics. Recommendations for situated and dynamic prevention are provided.

Paid employment and the changing system of gender relations: a cross-national comparison

Equality with men in the world of paid work has been a major feminist objective. Given that work in the `public' sphere has historically been shaped on the assumption that the `worker' will be male, then national employment systems which facilitate masculine employment patterns (i.e. full-time work and unbroken employment careers) might be expected to be more likely to generate gender equality. This paper compares women's employment in France (where `masculine' careers for women are common) and Britain (where part-time work and broken employment careers are more likely) at the macro, meso (occupational), and micro (individual) levels. The two occupations studied are finance and pharmacy. The evidence presented suggests that there are considerable similarities between women in the two countries at the occupational and individual level, despite national variations. In the light of this evidence, structural and individual explanations of women's employment behaviour are examined, and the continuing significance of structural constraint on the patterning of gender relations is emphasised.

The Impact of Personality and Culture on the Job Demands-Control Model of Job Stress

Among the various work stress models, one of the most popular has been the job demands-control (JDC) model developed by Karasek (1979), which postulates that work-related strain is highest under work conditions characterized by high demands and low autonomy. The absence of social support at work further increases negative outcomes. This model, however, does not apply equally to all individuals and to all cultures. This review demonstrates how various individual characteristics, especially some personality dimensions, influence the JDC model and could thus be considered buffering or moderator factors. Moreover, we review how the cultural context impacts this model as suggested by results obtained in European, American, and Asian contexts. Yet there are almost no data from Africa or South America. More crosscultural studies including populations from these continents would be valuable for a better understanding of the impact of the cultural context on the JDC model.

The therapeutic potential of immune cross-talk in leishmaniasis.

Veterans of infection, Leishmania parasites have been plaguing mammals for centuries, causing a morbidity toll second only to that of malaria as the most devastating protozoan parasitic disease in the world. Cutaneous leishmaniasis (CL) is, by far, the most prevalent form of the disease, with symptoms ranging from a single self-healing lesion to chronic metastatic leishmaniasis (ML). In an increasingly immunocompromised population, complicated CL is becoming a more likely outcome, characterized by severely inflamed, destructive lesions that are often refractory to current treatment. This is perhaps because our ageing arsenal of variably effective antileishmanial drugs may be directly or indirectly immunomodulatory and may thus have variable effects in each type and stage of CL. Indeed, widely differing immune biases are created by the various species of Leishmania, and these immunological watersheds are further shifted by extrinsic disturbances in immune homeostasis. For example, we recently showed that a naturally occurring RNA virus (Leishmania RNA virus (LRV)) within some Leishmania parasites creates hyperinflammatory cross-talk, which can predispose to ML: a case of immunological misfire that may require a different approach to immunotherapy, whereby treatments are tailored to underlying immune biases. Understanding the intersecting immune pathways of leishmaniasis and its co-infections will enable us to identify new drug targets, and thereby design therapeutic strategies that work by untangling the immunological cross-wires of pathogenic cross-talk.

Online teaching of inflammatory skin pathology by a French-speaking international university network

Introduction: Developments in technology, webbased teaching and whole slide imaging have broadened the teaching horizon in anatomic pathology. Creating online learning material including many types of media like radiologic images, videos, clinical and macroscopic photographs and whole slides imaging is now accessible to almost every university. Unfortunately, a major limiting factor to maintain and update the learning material is the amount of work, time and resources needed. In this perspective, a French national university network was initiated in 2011 to build mutualised online teaching pathology modules with clinical cases and tests. This network has been extended to an international level in 2012-2014 (Quebec, Switzerland and Ivory Coast). Method: One of the first steps of the international project was to build a learning module on inflammatory skin pathology intended for interns and residents of pathology and dermatology. A pathology resident from Quebec spent 6 weeks in France and Switzerland to develop the contents and build the module on an e-learning Moodle platform (http: //moodle.sorbonne-paris-cite.fr) under the supervision of two dermatopathologists (BV, MB). The learning module contains text, interactive clinical cases, tests with feedback, whole slides images (WSI), images and clinical photographs. For that module, the virtual slides are decentralized in 2 universities (Bordeaux and Paris 7). Each university is responsible of its own slide scanning, image storage and online display with virtual slide viewers. Results: The module on inflammatory skin pathology includes more than 50 web pages with French original content, tests and clinical cases, links to over 45 WSI and more than 50 micro and clinical photographs. The whole learning module is currently being revised by four dermatopathologists and two senior pathologists. It will be accessible to interns and residents in spring 2014. The experience and knowledge gained from that work will be transferred to the next international fellowship intern whose work will be aimed at creating lung and breast pathology learning modules. Conclusion: The challenges of sustaining a project of this scope are numerous. The technical aspect of whole-slide imaging and storage needs to be developed by each university or group. The content needs to be regularly updated, completed and its use and existence needs to be promoted by the different actors in pathology. Of the great benefits of that kind of project are the international partnerships and connections that have been established between numerous Frenchspeaking universities and pathologists with the common goals of promoting education in pathology and the use of technology including whole slide imaging. * The Moodle website is hosted by PRES Sorbonne Paris Cité, and financial supports for hardware have been obtained from UNF3S (http://www.unf3s.org/) and PRES Sorbonne Paris Cité. Financial support for international fellowships has been obtained from CFQCU (http://www.cfqcu.org/).

The learning module contains text, interactive clinical cases, tests with feedback, virtual slides, images and clinical photographs. For that module, the virtual slides are decentralized in 2 universities (Bordeaux and Paris 7). Each university is responsible of its own slide scanning, image storage and online display with virtual slide viewers. RESULTS: The module on inflammatory skin pathology includes more than 50 web pages with French original content, tests and clinical cases, links to over 45 virtual images and more than 50 microscopic and clinical photographs. The whole learning module is being revised by four dermatopathologists and two senior pathologists. It will be accessible to interns and residents in the spring of 2014. The experience and knowledge gained from that work will be transferred to the next international resident whose work will be aimed at creating lung and breast pathology learning modules. CONCLUSION: The challenges of sustaining a project of this scope are numerous. The technical aspect of whole-slide imaging and storage needs to be developed by each university or group. The content needs to be regularly updated and its accuracy reviewed by experts in each individual domain. The learning modules also need to be promoted within the academic community to ensure maximal benefit for trainees. A collateral benefit of the project was the establishment of international partnerships between French-speaking universities and pathologists with the common goal of promoting pathology education through the use of multi-media technology including whole slide imaging.
