The three webs: an attempt at an understanding of the future

This article poses questions about the significance of increased internationalization of science which has developed since the cold war. It deals with three different aspects of present-day science: particle ptpsics, nanotechnology and space exploration. In a simple way, research can be divided into three different froms: information (which, by definition, I call public), knowledge (that is, covered by intellectual property rights (IPR)) and training. Further, I assume that innovation is commercial and thus has a profit motive, in contrast with the scientific goal of enlarging our view of the universe. There is, however, a more fundamental issue which is the realization that the type of accounting economy we have is too naive to develop our society further. Consider figures form the US Department of Commerce-if research is one cost unit, engineering to protogpe is three and full production 20, or even 50 for pharmaceuticals. These figures indicate the present importance placed on rates of return on capital in assessing the effectiveness of research.     

A combination of differentiation and consolidation theory and risk-benefit analysis to examine decisions on mastitis prevention

Abstract

Mastitis infections cause severe pain in dairy cows and are the most costly illness to farmers. This study combined differentiation and consolidation (Diff-Con) theory with risk-benefit analysis to explore how risky decisions are perceived and justified after a decision has been taken. More specifically, using survey data from 428 Swedish dairy farmers, their decisions about adopting preventive measures to control mastitis (mastitis control options, MCO) in dairy herds were examined. The analyses included group comparisons with non-parametric rank tests and use of both ordinary least squared regression and seemingly unrelated regression analysis to examine how prior adoption of MCO affects farmers’ attitudes to the MCO. The results showed that MCOs already adopted were rated higher in perceived riskiness (if not implemented) and in expected benefit (for illness prevention) than non-adopted MCOs. Having made the decision to implement a strategy increased the likelihood of that decision being perceived as more beneficial (reducing mastitis) and risky (in terms of disease increase if not implemented), irrespective of the combination of strategies used on the farm, during the post-consolidation stage. No difference in perceived illness prevalence could explain the farmers’ rating of the MCOs. These findings suggest that there may be a path dependency in farmers’ decision-making with respect to MCO. This implies that novel MCOs may have difficulty in achieving wider implementation. These results have implications for the development of strategies to communicate best practices for use of MCOs and for new research on MCOs and farmers’ decision-making.     

Labor Taxation and FDI Decisions in the European Union

This paper uses panel data on bilateral FDI stocks in the European Union to empirically analyze the impact of labor and corporate taxations on FDI decisions. While the effect of corporate taxes on FDI is well documented, the impact of labor taxes on FDI has barely been explored. This is surprising since labor taxation may influence FDI as well; the taxation of labor affects the production cost and the ability to attract and retain productive labor, and thereby it also, ultimately, impacts the return to the investment. By employing a Heckman two-step estimation model, which controls for possible sample selection bias due to many zero bilateral observations, we find that labor taxes do influence FDI decisions.     

Tax revenue and the marginal cost of public funds in Sweden

We assess the welfare cost of raising a marginal unit of tax revenue in a balanced-budget, general-equilibrium framework. The calculated social cost of an increment of public funds is sensitive to both the specific type of tax increase and the type of public spending used on the margin. ‘Best-guess’ assumptions on labor supply elasticities yield marginal costs of public funds for different fiscal mixes of between 0.67 and 4.51 at prevailing tax rates in Sweden. Alternative labor supply assumptions well within the range of current estimates substantially affect the results and can imply infinite marginal welfare costs. Marginal welfare costs are also sensitive to assumptions about both the income and substitution effects of labor supply.     

Perceptions of predictive testing for those at risk of developing a chronic inflammatory disease: a meta-synthesis of qualitative studies*

Background: The availability of tests to predict the risk of developing chronic diseases is increasing. The identification of individuals at high risk of disease can trigger early intervention to reduce the risk of disease and its severity. In order for predictive tests to be accepted and used by those at risk, there is a need to understand people’s perceptions of predictive testing. Method: A meta-synthesis of qualitative research that explored patient and public perceptions of predictive testing for chronic inflammatory diseases was conducted. Studies were coded by researchers and patient research partners, and then organised into common themes associated with the acceptability or use of predictive testing. Results: Perceived barriers to predictive testing were identified, including a concern about a lack of confidentiality around the use of risk information; a lack of motivation for change; poor communication of information; and a possible impact on emotional well-being. In order to reduce these barriers, the literature shows that a patient-centred approach is required at each stage of the testing process. This includes the consideration of individual needs, such as accessibility and building motivation for change; readily available and easy to understand pre and post-test information; support for patients on how to deal with the implications of their results; and the development of condition specific lifestyle intervention programmes to facilitate sustainable lifestyle changes. Conclusion: Patients and members of the public had some concerns about predictive testing; however, a number of strategies to reduce barriers and increase acceptability are available. Further research is required to inform the development of a resource that supports the individual to make an informed decision about whether to engage in a predictive test, what test results mean, and how to access post-test support.     

Five charges against the precautionary principle

We defend the precautionary principle against five common charges, namely that it is ill-defined, absolutist, and a value judgement, increases risk-taking, and marginalizes science. We argue, first, that the precautionary principle is, in principle, no more vague or ill-defined than other decision principles and like them it can be made precise through elaboration and practice. Second, the precautionary principle need not be absolutist in the way that has been claimed. A way to avoid this is through combining the precautionary principle with a specification of the degree of scientific evidence required to trigger precaution, and/or with some version of the de minimis rule. Third, the precautionary principle does not lead to increased risk-taking, unless the framing is too narrow, and then the same problem applies to other decision rules as well. Fourth, the precautionary principle is indeed value-based, but only to the same extent as other decision rules. Fifth and last, the precautionary principle is not unscientific other than in the weak sense of not being exclusively based on science. In that sense all decision rules are unscientific.
