L’analyse des risques psychosociaux en ESAT parmi des travailleurs en situation de handicap (TSH) : éléments de réflexion

Unlike the mainstream world of labour, studies on psychosocial risks (PSR) in Establishments and Work Assistance Services (ESAT) among workers with disabilities are scarce. Given the adverse effects of the PSR on both these workers and on the work itself, it seems essential to focus specifically on the PSR in the context of ESAT. The paper shows that the application of different theoretical models of PSR from the mainstream environment to the ESAT is possible. The health at work for people with disabilities requires taking into account the disorders influencing the identification and the mobilization of resources and skills. Working conditions in ESAT allow health promotion if they are adapted to the specificities and needs of people with disabilities.     

The effects of noncontingent access to single- versus multiple-stimulus sets on self-injurious behavior

The automatically reinforced self-injury of a girl with autism was treated by providing noncontingent access to a single set of preferred toys during 30-min sessions. The reductive effects of the intervention waned as the session progressed. Rotating toy sets after 10 min or providing access to multiple toy sets resulted in reductions that lasted the entire 30 min.     

Choice in a variable environment: every reinforcer counts

Six pigeons were trained in sessions composed of seven components, each arranged with a different concurrent-schedule reinforcer ratio. These components occurred in an irregular order with equal frequency, separated by 10-s blackouts. No signals differentiated the different reinforcer ratios. Conditions lasted 50 sessions, and data were collected from the last 35 sessions. In Part 1, the arranged overall reinforcer rate was 2.22 reinforcers per minute. Over conditions, number of reinforcers per component was varied from 4 to 12. In Part 2, the overall reinforcer rate was six per minute, with both 4 and 12 reinforcers per component. Within components, log response-allocation ratios adjusted rapidly as more reinforcers were delivered in the component, and the slope of the choice relation (sensitivity) leveled off at moderately high levels after only about eight reinforcers. When the carryover from previous components was taken into account, the number of reinforcers in the components appeared to have no systematic effect on the speed at which behavior changed after a component started. Consequently, sensitivity values at each reinforcer delivery were superimposable. However, adjustment to changing reinforcer ratios was faster, and reached greater sensitivity values, when overall reinforcer rate was higher. Within a component, each successive reinforcer from the same alternative ("confirming") had a smaller effect than the one before, but single reinforcers from the other alternative ("disconfirming") always had a large effect. Choice in the prior component carried over into the next component, and its effects could be discerned even after five or six reinforcement and nonreinforcement is suggested.     

Fertile Ground for Community: Inner-City Neighborhood Common Spaces

Research suggests that the formation of neighborhood social ties (NSTs) may substantially depend on the informal social contact which occurs in neighborhood common spaces, and that in inner-city neighborhoods where common spaces are often barren no-man's lands, the presence of trees and grass supports common space use and informal social contact among neighbors. We found that for 145 urban public housing residents randomly assigned to 18 architecturally identical buildings, levels of vegetation in common spaces predict both use of common spaces and NSTs; further, use of common spaces mediated the relationship between vegetation and NSTS. In addition, vegetation and NSTs were significantly related to residents' senses of safety and adjustment. These findings suggest that the use and characteristics of common spaces may play a vital role in the natural growth of community, and that improving common spaces may be an especially productive focus for community organizing efforts in inner-city neighborhoods.     

AN ANALOGUE EVALUATION OF ENVIRONMENTAL ENRICHMENT: THE ROLE OF STIMULUS PREFERENCE

To evaluate the effects of environmental enrichment on stereotypic self-injurious behavior (SIB), we conducted an assessment of preference for manipulating alternative stimuli rather than engaging in SIB. First, for each of 3 participants, a functional analysis of SIB was conducted in Phase 1. Participants were selected for Phase 2 if the functional analysis showed that SIB persisted in the absence of social consequences. In Phase 2, a preference assessment was conducted in which participants were observed manipulating preferred stimuli in a free-operant format. A measure was taken of time spent manipulating each stimulus and time spent engaging in SIB. In Phase 3, environmental enrichment was evaluated using stimuli that were preferred over the target response, and alternative treatments were evaluated in the event of environmental enrichment failure. Results suggested that the free-operant preference assessment (a) predicted the efficacy or inefficacy of an environmental enrichment procedure and (b) suggested possible treatment alternatives when environmental enrichment was ineffective. Collectively, the results may provide a basis for interpreting the idiosyncratic effects of environmental enrichment and a rationale for treatment selection when behavioral function is unknown.     

Environmental factors and sense of community in a planned town

Previous community psychology research has suggested that sense of community can be a powerful explanatory tool for understanding community development and individual well-being, but has not focused on the relationship of environmental variables to the construct. In other disciplines—especially urban planning—this construct has received more attention but it has not been empirically and systematically studied. The three-phase qualitative study reported here sampled people representative of those who live and work in Seaside, FL, a town designed to induced sense of community. The data strongly suggest a relationship between a variable set that may define sense of community—membership, need fulfillment, shared emotional connections, loyalty—and the environmental variables of town design, architecture, and urban planning philosophy.     

The development of optimism and perceived attainment from elementary school to junior high school

Optimism (a perception of future improvement of children's own achievement levels) and perceived present attainment were examined developmentally in relation to academic achievement and motivation. Subjects were 507 Japanese third-, fifth-, and seventh-grade children. After categorization as high or low on perceived attainment (H/L) and optimism (h/l), two (Hh, Ll), three (Hh, Lh, Ll), and four (Hh, Hl, Lh, Ll) groups were obtained in the third, fifth, and seventh grades, respectively. These groups showed characteristic features in terms of motivation- and achievement-related measures. Both optimism and perceived attainment explained the differences in scores on the measures between the two third-grade groups. In grades 5 and 7 perceived attainment was the primary factor explaining the group differences, while the optimism dimension was a secondary factor, whose influence was stronger in grade 7. The results are discussed in relation to the development of self-perceptions, as well as changes in learning environment between elementary school and junior high school.     

Culture and Japanese Citizen Influence on the Transboundary Air Pollution Issue in Northeast Asia

This paper outlines a general approach for analyzing the role of culture in international environmental policymaking. It draws on work in anthropology and foreign policy analysis. The first step is to view culture as a “toolkit of environmental ideas.” The second step, relative to a given research topic, is to delimit broad definitions of culture to more workable forms. Three forms are offered (following Hudson, 1997a): culture as organization of environmental meaning, as shared value preferences in environmental matters, and as templates for environmental action. The third step is to answer three basic questions relative to the specific definition of culture used: (a) Who draws what environmentally related ideas from the ideas toolkit? (b) How are these ideas used in the political arena? (c) How do these ideas, originally drawn upon for political purposes, change and in turn lead to changes in the set of environmentally related ideas in the culture? Ideas, once they have entered the political arena, are assumed to be embodied in a “discourse.” The terminology of discourse (and the body of theory built up around it) is used as a vehicle for examining the role of culture in international environmental policymaking. A practical application of this approach is presented in relation to the role of culture in the Japanese public's influence in Japan on policymaking on the northeast Asian transboundary air pollution issue.     

Technology and the management of trust in insurance medicine

This article deals with the question how technologycontributed to the performing of objective assessmentsof health risks and to the public trust in theinsurance institution. Many authors have pointed tothe relevance of medical or statistical technologywith regard to the constitution of objectivity,because these technologies should be capable ofdiminishing the influence of social interactions – the``human element' – on the process of producingknowledge about health risks. However, in this articleit is shown that the constitution of objective riskassessments and public trust cannot be seen as theproduct of one particular type of technology, but thatit is the product of a socio-technical network, inwhich several heterogeneous elements becomeinterrelated and interdependant. The historicalreconstruction of this network also sheds a new lighton the role of `the human element' in the constitutionof objectivity and trust. It shows that elements inthe network which regulate the social interactionbetween the subjects involved are of no lessimportance to generate trust than technologies whichtend to abstract from this interaction. In otherwords, objective and subjective elements areintertwined much more than is often recognized, andpublic trust is to a fairly large degree depends onconventions in social interaction.
