Relations between environmental problems,psychology and health among shift-workers in the Norwegian process industry

Abstract

A group of 89 male shift-workers, mean age 38 years, was examined for health complaints, subjective experience of their work environment, psychological defence strategies, and immunological factors. They worked in a process industry, controlling a complex chemical process partly by instruments and partly by direct checking of mechanical devices such as valves. Shifts were eight hours long and changed every second week.

The main problem areas identified were problems with the management, colleagues and superiors, feelings of being under-valued, time pressure, fear of making mistakes, and lack of influence and communication. The main health complaints were sleep disturbance and gastro-intestinal problems. Shift workers also complained about allergies, breathing difficulties, tension, anxiety and depression. There were no pathological levels of plasma immunoglobulins (Ig) or Ig complements. However, levels did correlate with experience of work-related problems and with measures of defence mechanisms. Up to 25% of the variance in die immunological indicators was explained by a combination of defence mechanism scores and those of perceived health and work problems. This suggests that immunoglobulins may be an indicator of work-related health risks (‘stress’), even if the level of explained variance is too low to use immunoglobulins alone as a ‘marker’. The same variables, and immunoglobulins, also related significantly to perceived health. This may be a particularly important indicator, and when combined with immunology and psychological variables, also as a risk factor for organic disease.     

Split Return: Transnational Household Strategies in Afghan Repatriation

Split return is a common strategy of repatriation among refugees and migrants. Facing great uncertainty, both economically and security‐wise, households disperse in two or more locations in order to minimize risk. The phenomenon is well‐known in migration studies and in studies of return from the distant diaspora, but is studied less among the overwhelming majority residing in countries neighbouring their own. This article draws on experiences from Afghanistan, comparing split return to similar strategies in migration generally and in refugee situations specifically. It suggests that while splits are conceived as a temporary measure, they often become a lasting form of life. Opportunities for split return are often crucial for the willingness to start repatriation, as well as for the sustainability of the household's economy upon return. The article develops the concept of split return in relation to contextual factors, intensity of networks (at origin and in exile) and household composition.     

Sprachpolitik und gesellschaftliche Heterogenität in Europa: das Beispiel des mehrsprachigen Raums Luxemburg

The objective of this article is to analyse the interrelation of language, political power and society under conditions of heterogeneity from an interdisciplinary point of view. The analytical focus centres on potentials of societal integration through language policy measures in the European context. The complexity of multilingual situations in Europe is presented and evaluated by the situation of Luxembourg, because of supposed general and structural resemblances of the luxembourgish case to the European level. Central aim of the case study is to develop theses in relation to language and/in society for a European level in a comparative perspective. The article concludes that less institutionalized and static regulations of language policies could serve as a sensible basis for social processes in multilingual societies and suggests that supposedly simple solutions are to be considered in a critical manner.     

Non-welfaristic theories of justice: Is “the intersection approach” a solution to the indexing impasse?

Rawls (1971, 1993) suggests that a primary goods index should be the basis for interpersonal comparisons in a theory of justice, but it is well known that in general this approach is not compatible with the Pareto principle. This is the indexing impasse. Sen (1985, 1991) argues that this is partly due to the fact that the approach does not take note of the citizens orderings of these bundles of valuable objects. He suggests an intersection approach, which is an incomplete approach to interpersonal comparisons based on judgements that are shared implications of the relevant set of weighting schemes. In this paper, we show that the intersection approach does not provide any solution to the indexing impasse. Unless the individuals have identical preferences, the intersection approach is incompatible with the Pareto principle. This paper originates from the second chapter of Brun (1998). An earlier version was presented at a conference on Non Welfaristic Issues in Normative Economics at the University of Caen in June 1999, and we should like to thank the participants at the conference for their discussion of the paper.

Demographic Correlates and Judicial Determinations of Child Sexual Abuse Offenses

This study involved an in-depth evaluation of court records and various investigation reports of 532 alleged child sex offenders as well as their interactions with the typical societal intervention mechanism. The major results indicated that offenders significantly differed from the general population in various background characteristics. Generally, alleged offenders were more likely to be from certain demographic groups such as male, minorities, the poorly educated, labor workers, and the unemployed. Comparisons between subgroups defined by prior mental health, substance abuse, and childhood experiences indicated that negative background characteristics were further associated with the severity and judicial outcome of the charges. These results suggest the complexity of determining the etiology, correlates, and criminal and judicial dispositions of child sexual victimization. Finally, this study questions the sufficiency of the current quarantine approach, which segregates perpetrators through the mandatory registration and general distribution of the identities of convicted offenders. Implications were made regarding the need for integrating various academic disciplines and for coordinating the services of societal intervention units.     

Efficient ways to impute incomplete panel data

We find that existing multiple imputation procedures that are currently implemented in major statistical packages and that are available to the wide majority of data analysts are limited with regard to handling incomplete panel data. We review various missing data methods that we deem useful for the analysis of incomplete panel data and discuss, how some of the shortcomings of existing procedures can be overcome. In a simulation study based on real panel data, we illustrate these procedures’ quality and outline fruitful avenues of future research.     

BIDDING FOR HORIZONTAL MULTINATIONALS

We present a model in which governments bid for firms by taxing/subsidizing setup costs. Firms choose both the number and the location of the plants they operate, and the equilibrium industry structure is affected by governments' subsidy choices. We show that the endogenous presence of horizontal multinationals attenuates the race to the bottom and yields some results that run counter to traditional findings in the literature. First, in the presence of multinationals, increasing subsidies decrease firms' profits by exacerbating price competition due to more firms going multinational. Second, instead of being always subsidized, firms may actually be taxed in equilibrium. Last, subsidies may become strategically independent policy instruments, instead of being strategic complements. (JEL: F12, F23, H27, H73, R12)
