Risk perception and the location of a repository for spent nuclear fuel

This study investigates lay people's reactions to a repository for nuclear waste. Risk perception is seen as a complex concept, comprising both affective and cognitive components. Attitude towards nuclear power and trust in experts and authorities had a substantial impact on risk perception, while personal knowledge about nuclear waste disposal had no effect. Thus, the more positive one's attitude towards nuclear power is and the more trust one has in experts and authorities, the lower one's risk perception is. Also, reactions were expected to vary with distance between the home district and the location of a repository. These variations differed in nature for people with alternative levels of risk judgement. The distance between the home and a repository affected approval of the proposed site. Distance between home and repository also had an effect on risk feelings and somewhat less on beliefs about consequences. Estimated total risk was directly mediated by beliefs about consequences, but even more so by risk feelings. With regard to risk, one can conclude that it is important to make a distinction between an emotional and a cognitive component of risk perception.     

Long-Term stress reactions in new immigrants to israel exposed to the chernobyl accident

Abstract

This comparison study examined the relation between presumed level of exposure to the accident at Chernobyl in 1986 to symptoms of post-traumatic stress disorder (PTSD) and other psychological symptoms (depression, somatization, anxiety, obsessive-compulsive style and interpersonal sensitivity), life events and the negative appraisal of the events surrounding the accident. The sample (N = 708) included new immigrants from the former Soviet Union (Confederation of Independent States) who arrived in Israel since 1989 from more exposed areas (n = 137), less exposed (n = 240) and a comparison sample (n = 331) who immigrated from other republics. The exposed groups had higher mean scores on all psychological outcome measures than the comparison group, particularly symptoms of PTSD. Both subsequent stressful life events and a negative, cognitive assessment of events contributed to present psychological distress, independent of exposure.     

Questioning nuclear waste substitution: a case study

This article looks at the ethical quandaries, and their social and political context, which emerge as a result of international nuclear waste substitution. In particular it addresses the dilemmas inherent within the proposed return of nuclear waste owned by Japanese nuclear companies and currently stored in the United Kingdom. The UK company responsible for this waste, British Nuclear Fuels Limited (BNFL), wish to substitute this high volume intermediate-level Japanese-owned radioactive waste for a much lower volume of much more highly radioactive waste. Special focus is given to ethical problems that they, and the UK government, have not wished to address as they move forward with waste substitution. The conclusion is that waste substitution can only be considered an ethical practice if a set of moderating conditions are observed by all parties. These conditions are listed and, as of yet, they are not being observed.     

Intonation in the monosyllabic utterances of 1-year-olds

Previous research has demonstrated that falling contours predominate in infant utterances as early as 3 months of age. The precocious appearance of falling intonation is usually attributed to “biological tendencies,” that is, the physiological naturalness of descending fundamental frequency patterns. In contrast, other investigations have shown that some children do not use adultlike falling or rising intonation contours until they produce their first words. To resolve these conflicting views of prosodic development, this study acoustically investigated intonation production in the monosyllabic utterances of 10 English-speaking children from 10 to 13 months of age and the utterance-final monosyllables of ten 4-year-olds. Children in both age groups produced a wider accent range in falling contours than in rising contours. Infants produced a narrower accent range than the preschoolers. The findings suggest that biological tendencies are not sufficient to account for children’s acquisition of intonation between the ages of 1 and 4 years.     

On Human Survival: Reflections on Survival Research and Survival Policies

A new academic discipline, Survival Research, is proposed to investigate how the survival of the human species and its civilizations can be assured. Today nuclear weapons, overpopulation, and the deteriorating environment threaten our future. These phenomena are interconnected, and must be considered together in their complexity in an interdisciplinary manner. Some major obstacles to a wider awareness of the problems and solutions are described. Survival issues, primarily ecological ones, have lately lost ground, especially in the United States. It is essential that those still concerned, especially teachers and journalists, be informed about the problems and the urgency for finding solutions.     

Patenting humans: Clones,chimeras, and biological artifacts

The momentum of advances in biology is evident in the history of patents on life forms. As we proceed forward with greater understanding and technological control of developmental biology there will be many new and challenging dilemmas related to patenting of human parts and partial trajectories of human development. These dilemmas are already evident in the current conflict over the moral status of the early human embryo. In this essay, recent evidence from embryological studies is considered and the unbroken continuity of organismal development initiated at fertilization is asserted as clear and reasonable grounds for moral standing. Within this frame of analysis, it is proposed that through a technique of Altered Nuclear Transfer, non-organismal entities might be created from which embryonic stem cells could be morally procured. Criteria for patenting of such non-organismal entities are considered. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.     

Task complexity matters: The influence of trait mindfulness on task and safety performance of nuclear power plant operators

People with high level of trait mindfulness are more likely to maintain an open and present-focused awareness and attention. Whereas a positive link between trait mindfulness and well-being has been established, its influence on real-world performance has not been fully addressed. In Study 1, we validated the Freiburg Mindfulness Inventory (FMI) in a Chinese sample (N = 294) and found that a two-dimensional solution (a presence factor and an acceptance factor) best fit the data. In Study 2, using this validated scale, we directly investigated the influence of trait mindfulness on task and safety performance. In a sample of 136 Chinese nuclear power plant operators, it was found that trait mindfulness interacted with task complexity to influence performance. For high-complexity-task holders (the control room operators), the presence factor was positively related to their task and safety performance; for the low-complexity-task holders (the field operators), the presence factor had no influence on safety performance but a negative influence on task performance. The acceptance factor did not have any meaningful influences. These results suggest that the benefit of being mindful outweighs its cost for complex but not simple tasks. Implications are discussed.     

The Primary Triangle and Variation in Nuclear Family Functioning

The triangle, a concept in Bowen theory, is the emotional molecule in the family system that shapes the human over the course of life. This longitudinal study explored the influence of the family of origin primary triangle on 51 couples’ family of procreation functioning over 10 years. The quantitative analysis found associations between family of procreation functioning and three variables: distance versus openness in the family of origin primary triangle, the degree of inside and outside positions in the primary triangle, and the degree of family projection as expressed in worry. In addition, the three triangle relationships correlated with each other, supporting the idea that each relationship influenced the other. Using qualitative methods, a focused analysis elaborated on the quantitative findings.     

Joseph Rotblat and the Moral Responsibilities of the Scientist

Professor Sir Joseph Rotblat was one of the most distinguished scientists and peace campaigners of the post second world war period. He made significant contributions to nuclear physics and worked on the development of the atomic bomb. He then became one of the world’s leading researchers into the biological effects of radiation. His life from the early 1950s until his death in August 2005 was devoted to the abolition of nuclear weapons and peace. For this he was awarded the Nobel Peace Prize, together with Pugwash Conferences on Science and World Affairs (that he helped found) in 1995. His work in this area ranked with that of Albert Einstein and Bertrand Russell and this article is an attempt to summarise his life, achievements, but in particular outline his views on the moral responsibilities of the scientist. He is a towering intellectual figure and his contributions to mankind should be better known and more widely understood.

To Recycle or Not to Recycle? An Intergenerational Approach to Nuclear Fuel Cycles

This paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and proliferation concerns. However, it compromises short-term public health and safety and security, due to the separation of plutonium. The trade-offs in nuclear energy are reducible to a chief trade-off between the present and the future. To what extent should we take care of our produced nuclear waste and to what extent should we accept additional risks to the present generation, in order to diminish the exposure of future generation to those risks? The advocates of the open fuel cycle should explain why they are willing to transfer all the risks for a very long period of time (200,000 years) to future generations. In addition, supporters of the closed fuel cycle should underpin their acceptance of additional risks to the present generation and make the actual reduction of risk to the future plausible.
