Patterns of Conflict About Risky Technologies

This paper examines taxonomies for classifying risks and conflicts about risky technologies. First, we describe six levels of conflict that represent various " shades of gray" between purely factual and purely value laden conflicts in technology disputes. Subsequently, we survey several recent taxonomies of risks and hazards that were at least partly intended to clarify the nature of the public conflicts about technologies and their risks. After pointing out that non-risk features frequently shape technology debates, we develop a taxonomy of the disputes themselves, based on a collection of 162 cases. Our taxonomy of technological controversies is related to the recent risk taxonomies and to the different levels of conflict. It turns out that the different technological disputes create quite different levels of conflict ranging from mainly factual (consumer products, drugs) to extremely value laden (nuclear power, genetic engineering). Depending on the type of controversy and level of conflict we suggest alternative conflict management strategies.     

Norwegian lottery winners: Cautious realists

The study investigated 261 lottery winners of prizes of NKR 1 million (US $150,000) or more in the years 1987–91 in a postal survey. The modal Norwegian winners were middle-aged married men of modest education, living in small communities. Emotional reactions to winning were few, aside from moderate happiness and relief. Winners emphasized caution, emotional control and unconspicuous spending, e.g. paying debts and sharing with children. There was only a slight increase in economic spending. A wish for anonymity was frequent, together with fear of envy from others. Betting was modest both before and after winning. Experiences with winning were predominantly positive. Life quality was stable or had improved. An age trend was observed, accounting for more variance than any other variable. The older winners seemed to represent a puritan subculture of caution, modesty and emotional restraint. A slightly more impatient pattern of spending was characteristic of younger winners. The results support Kaplan's 1987 and others' findings that lottery winners are not gamblers, but self-controlled realists and that tenacious, negative cultural expectations to the contrary are myths, but perhaps also deterrents of uncontrolled behavior.     

Choosing Principal Components: A New Graphical Method Based on Bayesian Model Selection

This article approaches the problem of selecting significant principal components from a Bayesian model selection perspective. The resulting Bayes rule provides a simple graphical technique that can be used instead of (or together with) the popular scree plot to determine the number of significant components to retain. We study the theoretical properties of the new method and show, by examples and simulation, that it provides more clear-cut answers than the scree plot in many interesting situations.

Superior Sporting Performance in Athletics: Determinants and Sustainability

The article aims to contribute to the understanding of competitive dynamics and specialization in international sport by analyzing superior sporting performance (SSP) in international athletics in the period from 1999 to 2018. By applying iterative Kolmogorov‐Smirnov tests to annual bests, the study examines national SSPs. Contrary to theoretical considerations, less specialized countries are more likely to achieve SSP. Technical entry barriers and macrosocial factors also appear to play a limited role. SSP seems not to disappear due to increased international competition. The United States and Russia are identified as “sporting super powers,” able to persistently dominate a number of disciplines. The case of Russia poses fundamental questions concerning market distortions in international sport resulting from doping. The results come with substantial policy implications.     

Mixing Bismarck and child pension systems: an optimum taxation approach

Pensions with a strong tax–benefit link (Bismarck pensions) minimise the labour–leisure distortion of the public pension system. By contrast, pensions with a strong link of benefits to the number of children (child pensions) minimise the fertility distortion. When both types of distortion are present, we obtain a Corlett–Hague result regarding the optimal mix of the two pension formulae: the Bismack pension should be given a positive weight if and only if children are more complementary to leisure than consumption. Alternative fertility instruments such as child benefits turn out to be perfect substitutes to a child pension.     

Zu den Auswirkungen von Arbeitszeitmodellen im ärztlichen Dienst von Krankenhäusern

In 2004 a new working time law for physicians in hospitals was introduced, which has up until now been rarely researched in theory and is implemented in practice partially in form of new working time models, partially by relying on allowed variation rules within the law. Meanwhile, there are new discussions about changes of working time directives on the European level. This article aims to analyze the desired effects of the new working time law to decrease the workload, improve the possibilities of patient care and increase the working time satisfaction of physicians. To this end, a primary data collection is conducted in 15 hospitals and 35 hospital departments, generating 261 questionnaires, in order to empirically assess the theoretical model with the constructs working time model, workload, working time satisfaction, and possibilities of patient care using regression analyses. It can be shown that the new working time models decrease workload and enhance working time satisfaction of hospital physicians, but have no significant influence on the possibilities of patient care. These results are consistent for different ownerships and sizes of hospitals as well as for most services. No significant differences in the answers between various physician groups exist either.
