The ethics of doing policy relevant science: The precautionary principle and the significance of non-significant results

The precautionary principle is a widely accepted policy norm for decision making under uncertainty in environmental management, However, some of the traditional ways of ensuring trustworthy results used in environmental science and of communicating them work contrary to the general goal of providing the political system and the public with as good an input as possible in the decision making process. For example, it is widely accepted that scientists should only communicate results fulfilling the traditional scientific standard for hypothesis testing. The need for introducing complementary norms in environmental science is illustrated by a recent discussion among scientists on how the precautionary principle should be used in the context of marine biological studies. This discussion highlights the importance of the use of statistical power in communicating scientific results to decision makers and to the general public as well as to the scientific peers. We argue that it would be unethical to report only certainties—because of the need of early warnings—and it would in the same way be unethical to hide the uncertainties. Environmental science can make a better contribution to environmental decision making, if the available knowledge is communicated in a manner which allows for insight on how strong the evidence is.     

Trace classical conditioning in rainbow trout (Oncorhynchus mykiss): what do they learn?

There are two main memory systems: declarative and procedural memory. Knowledge of these two systems in fish is scarce, and controlled laboratory studies are needed. Trace classical conditioning is an experimentally tractable model of declarative memory. We tested whether rainbow trout (Oncorhynchus mykiss) can learn by trace conditioning and form stimulus–stimulus, as opposed to stimulus–response, associations. We predicted that rainbow trout trained by trace conditioning would show appetitive behaviour (conditioned response; CR) towards the conditioned stimulus (CS; light), and that the CR would be sensitive to devaluation of the unconditioned stimulus (US; food). The learning group (L, N = 14) was trained on a CS + US contingency schedule with a trace interval of 3.4 s. The control group (CtrL, N = 4) was kept on a completely random schedule. The fish that learnt were further trained as either an experimental (L, N = 6) or a memory control (CtrM, N = 3) group. The L group had the US devalued. The CtrM group received only food. No fish in the CtrL group, but nine fish from the L group conditioned to the light. When tested, five L fish changed their CRs after US devaluation, indicating learning by stimulus–stimulus association of the light with the food. CtrM fish retained their original CRs. To the best of our knowledge, this experiment is the first to show that rainbow trout can learn by trace classical conditioning. The results indicate that the fish learnt by ‘facts-learning’ rather than by reflex acquisition in this study.     

Through two lenses: A cultural–developmental approach to moral psychology

This paper proposes a cultural–developmental approach to moral psychology. The approach builds on and synthesizes findings from different research traditions, including the cognitive-developmental, domain, two orientations, three ethics, and moral identity traditions. The paper introduces a conception termed a cultural–developmental template. The template charts developmental patterns across the life course for moral reasoning in terms of the three Ethics of Autonomy, Community, and Divinity. The template, however, is not one-size-fits-all. Its general developmental patterns accommodate to the different constellations of Ethics held by culturally diverse peoples. From the present theoretical proposal follows a set of specific research expectations as well as a set of broader research implications for how to conduct research on morality from the vantage points of both culture and development. These expectations and implications include consideration of moral emotions, definitions of morality, and cultural variation in the life course itself.     

Changing caring behaviours in rehabilitation after a hip fracture – A tool for empowerment?

Different rehabilitation programs after surgery have been presented to improve the outcome for patients with a hip fracture. Empowerment has been suggested as useful, but requires a change in the caring behaviours of health professionals. The aim with this study was to evaluate if training and supervision of the nursing staff could alter caring behaviours. A case-control study of nursing staff treating hip fracture patients was performed at a hospital with two sites. Training and supervision was given to the nursing staff at the intervention site. The intervention focused on creating positive care interaction by using eight guidelines. The evaluation was performed with recordings of a constructed caring situation before training, and observations of care situations at the ward before and after intervention. The results showed no differences at baseline between the two sites in the caring behaviours. After intervention, significant effects of caring behaviours were seen in seven out of eight guidelines, the effect sizes ranged from medium to large. The findings indicate that the nursing staff can change caring behaviours and facilitate the empowerment of patients with a hip fracture.     

The Presence of Others

Hybrid accounts of folk psychology maintain that we sometimes theorize and sometimes simulate in order to understand others. An important question is why this is the case. In this paper, I present a view according to which simulation, but not theory, plays a central role in empathy. In contrast to others taking a similar approach to simulation, I do not focus on empathy’s cognitive aspect, but stress its affective-motivational one. Simulating others’ emotions usually engages our motivations altruistically. By vicariously feeling what others are feeling, we directly come to be motivated by their projects and concerns. Simulation contrasts with more theoretical approaches to psychological attribution that help us understand and explan others, but that do not move us altruistically. This helps us see why we would posit two different folk psychological approaches instead of merely one.     

Toward an Epistemology of the Hand

Western philosophy has been greatly influenced by visual metaphors. Knowing something has commonly, yet implicitly, been conceptualized as seeing something clearly, learning has been framed as being visually exposed to something, and the mind has been understood as a ‘mirror of nature’. A whole ‘epistemology of the eye’ has been at work, which has had significant practical implications, not least in educational contexts. One way to characterize John Dewey’s pragmatism is to see it as an attempt to replace the epistemology of the eye with an epistemology of the hand. This article develops the epistemology of the hand on three levels: A level of embodiment and metaphors, of craftsmanship and social practices, and of schooling and education.     

Ideological Views in Emerging Adulthood: Balancing Autonomy and Community

Ideological views of 140 emerging adults (ages 20–29) were explored, using the ethics of Autonomy, Community, and Divinity. Two questions were asked as part of an interview: “When you get toward the end of your life, what would you like to be able to say about your life, looking back on it?” and “What values or beliefs do you think are the most important to pass on to the next generation?” Overall, emerging adults used Autonomy and Community in roughly equal proportions, whereas Divinity was used relatively infrequently. Use of Autonomy was negatively correlated with use of Community on both questions, but the correlations were modest, and some emerging adults were able to reconcile the two ethics. Qualitative examples are presented to illustrate the findings of the study, and the findings are discussed in the context of claims about American individualism.     

Association between the Five Factor personality traits and perceived stress: is the effect mediated by general self-efficacy?

Ill-health resulting from chronic stress is influenced by personality traits leading to different ways of appraising and coping with life's daily hassles. Using a large population sample the study aimed to investigate possible associations between perceived stress and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and to explore the role of general self-efficacy (GSE). A population-based cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006-2008. Men and women (N=3471) aged 18-69, were randomly sampled in the suburbs of Copenhagen. We used the NEO Five-Factor Inventory (NEO-FFI), Cohen's Perceived Stress Scale and the General Self-Efficacy Scale. Negative associations were found between perceived stress and extroversion, conscientiousness, agreeableness, and openness - the latter initially non-significant - whilst neuroticism had a positive association. The associations with agreeableness and openness became positive and significant, respectively, when GSE was included. All five personality-stress models were mediated by GSE, with extroversion and conscientiousness having the strongest mediating effect. The strongest stress-association was found for neuroticism. GSE was shown to change the impact and interpretation of the personality dimensions on perceived stress. These results indicate that GSE is an important factor to consider in the link between personality and perceived stress.
