La tournée des facteurs Normes gestionnaires, régulation collective et stratégies d’activité

The work of mailmen is mainly defined by the delivery routes to which they are assigned. Since this special organization of work grants them broad autonomy, the processes for delimiting, defining, and conducting routes must be analyzed by taking into account observations from three levels. The first one focuses on the French Post Office’s managerial standards, which, though increasingly determined by objectives for making a profit, have little impact on mail deliverers’ activities. The second centers around this occupational group’s own regulations, which stem from a hierarchy based on seniority and control over mail delivery and routes. The third level of observation takes into view the strategies for delivering mail that postmen adopt on their routes. These strategies reflect different relations to managerial objectives and to customers; and they reveal contrasting conceptions of the job of delivering mail. Emphasis is laid on the fact that the situations for working at lower levels in the service sector cannot be separated from the factors defining and organizing these situations.     

Decentralizing Risk Analysis in Large Engineered Systems: An Approach to Articulating Technical and Socioorganizational Dimensions of System Performance1

Nuclear power production in France, as the domain of one national utility and one reactor builder, has a standardized profile of technical installations, safety procedures, and personnel qualifications. Despite this relative homogeneity, discrepancies are observed from one production unit to another, notably in the area of worker-safety performance. There is a strong implication for risk analysis: varying performance cannot be attributed solely to the technical dimensions of equipment, procedures, and human skills. The authors retain as a working hypothesis that safety performance is an outcome of interactions between technical and organizational factors. Traditional risk analysis appears to be underequipped to represent such interactions. The notion of decentralized risk analysis (DRA) is introduced as a means of achieving this goal. A program of applied research carried out in a NPP facility is presented. It aims at increasing, across plant work structure, knowledge and control of these interactions specific to the given context. Systematic measurements and feedback of social representations are performed, using a three-dimensional factor space of individual and organizational values. Direct involvement of the total plant population, transfer of analytic tools, methodological continuity, interactive elaboration of data, coordination of different levels of findings with operations, follow-up and feedback of measured change, are the main features of this DRA process. In the case cited, improvement observed in safety performance parallels changes in measured social representations. The value of DRA for articulating technical and organizational dimensions of risk, and for integrating information into decision-making, is argued.     

Influenza vaccine efficacy trials: a simulation approach to understand failures from the past

The success of a seasonal influenza vaccine efficacy trial depends not only upon the design but also upon the annual epidemic characteristics. In this context, simulation methods are an essential tool in evaluating the performances of study designs under various circumstances. However, traditional methods for simulating time‐to‐event data are not suitable for the simulation of influenza vaccine efficacy trials because of the seasonality and heterogeneity of influenza epidemics. Instead, we propose a mathematical model parameterized with historical surveillance data, heterogeneous frailty among the subjects, survey‐based heterogeneous number of daily contact, and a mixed vaccine protection mechanism. We illustrate our methodology by generating multiple‐trial data similar to a large phase III trial that failed to show additional relative vaccine efficacy of an experimental adjuvanted vaccine compared with the reference vaccine. We show that small departures from the designing assumptions, such as a smaller range of strain protection for the experimental vaccine or the chosen endpoint, could lead to smaller probabilities of success in showing significant relative vaccine efficacy.

Disrupting an imposed racial identity or performing the model minority? The pursuit of postsecondary education by young African immigrant men in Southern Ontario,Canada

ABSTRACT

This article examines how young African immigrant men in Southern Ontario cope with the dominant racial identity at school in an effort to improve their academic performance and access postsecondary education (PSE). Critical race theory in education is employed to explain how the young men distance themselves from stereotypes about Black masculinity by regulating their own behaviour and differentiating themselves from their Caribbean immigrant peers. Sixty-seven young men who had immigrated to Southern Ontario from several African countries over the last 10 years were interviewed individually and in focus groups for the study. The findings suggest that the research participants adopted a model minority status within an educational system that clearly embodies racist and systemically oppressive frameworks.     

How do middle-aged employees combine work with caring for elderly parents?

How common is it for elderly employees to experience a squeeze between work and care obligations for their parents, and to what extent does this affect their behaviour in working life? To illuminate these questions, this article presents findings from a representative survey conducted in Norway in 2007. One finding is that seven out of 10 respondents (with one or both parents still living) are both employed and caring for their elderly parents. Fifty-seven percent have experienced difficult situations in coping with both. The most preferable arrangement is flexible working hours. Employees prefer the possibility to reduce or stagger working hours, or the option to work from home if necessary.     

Norwegian cohort emigration

This paper introduces a counterfactual technique to estimate net emigration from Norwegian birth cohorts from 1846 to 1900. A main finding is that despite strong fluctuations in annual emigration, the percentage reduction of each cohort due to emigration was surprisingly stable for all cohorts from 1846 to 1886, with net emigration of about 30% for males and about 20% for females. Estimating an econometric model of annual male gross emigration by single years of age 15–60 in the period 1870–1914, we find that previous net emigration from a cohort reduces later gross emigration from the same cohort. The estimations also give some justification for attributing this to selectivity of emigration, in the sense that only a certain proportion of each cohort were potential migrants.

Individual and environmental factors related to job satisfaction in people with severe mental illness employed in social enterprises

Objective: The purpose of this study was to enhance understanding of the impact of individual and environmental variables on job satisfaction among people with severe mental illness employed in social enterprises.Participants: A total of 248 individuals with severe mental illness employed by social enterprises agreed to take part in the study. Methods: We used logistic regression to analyse job satisfaction. A model with job satisfaction as the dependent variable, and both individual (occupational self-efficacy and severity of symptoms perceived) and environmental (workplace) factors (provision of workplace accommodations, social support from co-workers, organizational constraints) as well as external factors (family support) as predictors, was tested on the entire sample. Results: All findings across the study suggest a significant positive impact of both individual and environmental factors on job satisfaction. People with higher occupational self-efficacy who were provided with workplace accommodations and received greater social support were more likely to experience greater job satisfaction.Conclusions: These results suggest that certain features of social enterprises, such as workplace accommodations, are important in promoting job satisfaction in people with severe mental illness. Further studies are warranted to expand knowledge of the workplace features that support employees with severe mental illness in their work integration process.     

Wage Flexibility for Skilled and Unskilled Workers: New Evidence on the Norwegian Wage Curve

Empirical evidence is provided in favour of a hypothesis that wages for unskilled workers are more responsive to unemployment than wages for skilled workers. The results imply vigorous wage responsiveness to low levels of unemployment for both groups, while the wage curves become almost entirely flat for unemployment rates above 1.7 percent. One interpretation of this result is that firms have strong incentives to increase wages in order to recruit and retain workers when unemployment is below some critical level. Since unemployed workers will certainly find work, the expected costs of a job loss are small, as are costs associated with an egalitarian wage policy.     

Quantitative risk assessment of rabies being introduced into mainland France through worldwide noncommercial dog and cat movements

France has been rabies-free among nonflying mammals since 2001. Despite this status, the rabies virus has been introduced several times through noncommercial pet movements, posing a threat of infection by this 100%-lethal zoonosis among local animal and human populations. To quantify the risk of rabies being introduced through worldwide noncommercial dog and cat movements, we performed a quantitative risk assessment using stochastic scenario tree modeling. The mean annual probability of at least one rabies introduction incident was 0.35 (median: 0.24, 90% prediction interval (PI) [0.04; 0.98]) and the mean annual number of rabies-infected pets introduced through pet movements was 0.96 (median: 0.27, 90% PI [0.04; 3.88]). These results highlight a nonnegligible, even high risk due to the associated consequences of such events. In alternative scenario testing, preventive anti-rabies vaccination proved to be an effective measure since removing the vaccination requirement led to a > 15-fold increase in risk. The serological testing requirement had less of an effect (approximately two-fold increase when removed) and the posttest waiting period to ensure that antibodies were not linked to an infection had a negligible effect. Any change in pet owner compliance, especially regarding vaccination, could have a major impact on the risk. This study also shows that reinforced border control staff training could be more effective in reducing risk than more frequent checks. These results provide quantitative data for assessing the probability of the rabies virus entering France, and could help policymakers decrease this risk in rabies-free areas.
