Wahrheitskommissionen als Instrument der Transitional Justice. Genese, Entwicklung, Verbreitung

Wahrheitskommissionen haben in den vergangenen rund dreißig Jahren eine bemerkenswerte internationale Karriere aufzuweisen gehabt. Sie haben sich dabei von einer der wichtigsten Innovationen im gesellschaftlichen Umgang mit historischem Unrecht zu einem globalen Aufarbeitungsstandard entwickelt. Bis in die Gegenwart sind Dutzende Wahrheitskommissionen auf fünf Kontinenten eingesetzt worden. Diese Entwicklung ist eng mit derjenigen des Feldes der Transitional Justice verbunden gewesen. Der Beitrag betrachtet die Genese, die Entwicklung und die Verbreitung der Wahrheitskommissionen als zentrales Instrument von Transitional Justice.

EMPLOYMENT AND EXPOSURES IN THE PETROLEUM REFINING AND PETROCHEMICAL INDUSTRIES AND THE RISK OF LUNG CANCER (EPIDEMIOLOGY, ASSESSMENT)

This dissertation addresses the risk of lung cancer associated with occupational exposures in the petroleum refining and petrochemical industries. Earlier epidemiologic studies of this association did not adjust for cigarette smoking or have specific exposure classifications. The Texas EXposure Assessment System (TEXAS) was developed with data from a population-based, case-comparison study conducted in five southeast Texas counties between 1976 and 1980. The Texas Exposure Assessment System uses job and process categories developed by the American Petroleum Institute, as well as time-oriented variables to identify high risk groups.^ An industry-wide, increased risk for lung cancer was associated with jobs having low-level hydrocarbon exposure that also include other occupational inhalation exposures (OR = 2.0--adjusted for smoking and latency effects). The prohibition of cigarette smoking for jobs with high-level hydrocarbon exposure might explain part of the increased risk for jobs with low-level hydrocarbon exposures. Asbestos exposure comprises a large part of the risk associated with jobs having other inhalation exposures besides hydrocarbons. Workers in petroleum refineries were not shown to have an increased, occupational risk for lung cancer. The increased risk for lung cancer among petrochemical workers (OR = 3.1--smoking and latency adjusted) is associated with all jobs that involve other inhalation exposure characteristics (not only low-level hydrocarbon exposures). Findings for contract workers and workers exposed to specific chemicals were inconclusive although some hypotheses for future research were identified.^ The study results demonstrate that the predominant risk for lung cancer is due to cigarette smoking (OR = 9.8). Cigarette smoking accounts for 86.5% of the incident lung cancer cases within the study area. Workers in the petroleum industry smoke significantly less than persons employed in other industries (p << 0.001). Only 2.2% of the incident lung cancer cases may be attributed to petroleum industry jobs; lifestyle factors (e.g., nutrition) may be associated with the balance of the cases. The results from this study also suggest possible high risk time periods (OR = 3.9--smoking and occupation adjusted). Artifacts in time-oriented findings may result because of the latency interval for lung cancer, secular peaks in age-, sex-specific incidence rates, or periods of hazardous exposures in the petroleum industry. ^

Long-term effectiveness of supported employment: 5-year follow-up of a randomized controlled trial

Objective The individual placement and support model of supported employment has been shown to be more effective than other vocational approaches in improving competitive work over 1-2 years in persons with severe mental illness. The authors evaluated the longer-term effects of the model compared with traditional vocational rehabilitation over 5 years. Method A randomized controlled trial compared supported employment to traditional vocational rehabilitation in 100 unemployed persons with severe mental illness. Competitive work and hospital admissions were tracked for 5 years, and interviews were conducted at 2 and 5 years to assess recovery attitudes and quality of life. A cost-benefit analysis compared program and total treatment costs to earnings from competitive employment. Results The beneficial effects of supported employment on work at 2 years were sustained over the 5-year follow-up period. Participants in supported employment were more likely to obtain competitive work than those in traditional vocational rehabilitation (65% compared with 33%), worked more hours and weeks, earned more wages, and had longer job tenures. Reliance on supported employment services for retaining competitive work decreased from 2 years to 5 years for participants in supported employment. Participants were also significantly less likely to be hospitalized, had fewer psychiatric hospital admissions, and spent fewer days in the hospital. The social return on investment was higher for supported employment participants, whether calculated as the ratio of work earnings to vocational program costs or of work earnings to total vocational program and mental health treatment costs. Conclusions The results demonstrate that the greater effectiveness of supported employment in improving competitive work outcomes is sustained beyond 2 years and suggest that supported employment programs contribute to reduced hospitalizations and produce a higher social return on investment.

Die grenzüberschreitende Übertragung von Wissen über Transitional Justice und ihre Akteure in historischer Perspektive

Historische Ansätze sind in der Betrachtung von Transitional Justice rar geblieben. Den weitreichenden Veränderungen, die das Feld im Zuge seiner Ausdehnung zum weltweit dominierenden Reflexions- und Handlungszusammenhang im Umgang mit historischem Unrecht erfahren hat, ist deshalb in aller Regel keine angemessene Beachtung geschenkt worden. Der vorliegende Beitrag widmet sich aus historischer Sicht den Fragen, wie seit den späten 1980er Jahren über die Grenzen nationaler Aufarbeitungsschauplätze hinaus Wissen über Transitional Justice generiert und übertragen worden ist, welche die beteiligten Akteursgruppen waren und welche Auswirkungen der Wandel in den Wissenstransfers und im Verhältnis zwischen den Akteuren auf die Entwicklungen im Feld hatte. Im Mittelpunkt der Analyse steht dabei das Instrument der Wahrheitskommissionen. Historical approaches to the study of transitional justice are rare. In the process of its expansion to the dominating paradigm in dealing with past injustices, the field experienced far reaching changes. Scholarship about transitional justice, however, has hardly taken into account these shifts in appropriate ways. This article examines from a historical point of view how knowledge about transitional justice was generated and transferred across the borders of the national sites of dealing with the past, what were the groups of actors involved and what effects the transformations of the knowledge circulation as well as of the relationship between the actors since the late 1980s had on the development of the field. The focus of the analysis, thereby, is on the instrument of truth commissions.

Quinoa production in the Nor Lipez province (Bolivia): Gender roles in export-led agriculture and challenges for research on rural employment

The recent increase in prices and production of quinoa have had important effects on the employment structures and livelihoods of rural communities in the Nor Lipez Province (Bolivia). The "quinoa boom" resulted in significant changes in household incomes and in gender roles in the context of increasing market integration. The nature of these changes however is not easy to grasp, as new official narratives on gender and on traditional systems of labour divisions and shared access to land have surfaced since the election of Evo Morales (2006) and the adoption of a new constitution (2009). Furthermore, rural employment is found to be much more diverse than the term suggests. Women have always participated in the production of quinoa when it was widely considered as a subsistence crop. Our research takes place in the Nor Lipez Province, Bolivia with exploratory studies that were conducted in January and February 2015 in 8 rural communities of quinoa producers. Preliminary results suggest positive effects for local women in that they managed to earn additional income which might have contributed to their empowerment. This article will present both preliminary results, challenges for gender-oriented research in Bolivia and the methodology aiming to capture changes at the individual, the household and the community level through a survey that will be conducted from September to November 2015 in 500 households.
