Reexamining the Ethics of Nuclear Technology

This article analyzes the present status, development trends, and problems in the ethics of nuclear technology in light of a possible revision of its conceptual foundations. First, to better recognize the current state of nuclear technology ethics and related problems, this article focuses on presenting a picture of the evolution of the concepts and recent achievements related to technoethics, based on the ethics of responsibility. The term ‘ethics of nuclear technology’ describes a multidisciplinary endeavor to examine the problems associated with nuclear technology through ethical frameworks and paradigms. Second, to identify the reasons for the intensification of efforts to develop ethics in relation to nuclear technology, this article presents an analysis of the recent situation and future prospects of nuclear technology deployment. This includes contradictions that have aggravated nuclear dilemmas and debates stimulated by the shortcomings of nuclear technology, as well as the need for the further development of a nuclear culture paradigm that is able to provide a conceptual framework to overcome nuclear challenges. Third, efforts in the field of nuclear technology ethics are presented as a short overview of particular examples, and the major findings regarding obstacles to the development of nuclear technology ethics are also summarized. Finally, a potential methodological course is proposed to overcome inaction in this field; the proposed course provides for the further development of nuclear technology ethics, assuming the axiological multidisciplinary problematization of the main concepts in nuclear engineering through the basic ethical paradigms: analytical, hermeneutical, and poststructuralist.     

The Perception of Honour-Related Violence in Female and Male University Students from Morocco,Cameroon and Italy

The study investigates the perception of honour-related violence against women in female and male university students from three countries - Morocco, Cameroon, Italy – all considered honour cultures but different in terms of various other sociocultural factors, such as family structure and gender roles. One hundred fourteen Moroccan (47 females, 67 males), 106 Cameroonian (41 females, 65 males) and 103 Italian (51 females, 52 males) students attending Turin University and currently living in Turin, answered a questionnaire to evaluate an act of honour-related violence by a father against his daughter. The results showed that the perception of this act was influenced by the participants’ nationality: Italians evaluated the incident as more serious and more as a crime than Moroccans, and the latter more than Cameroonians. Furthermore, Italians attributed less responsibility to the victim and more responsibility to the assailant than Moroccans and Cameroonians did; accordingly, they also proposed more severe punishment for the assailant than Moroccans and Cameroonians. The results also showed an interaction between nationality and gender: Cameroonian women attributed more responsibility to the victim and less to the assailant than Cameroonian men, and Italian men attributed less responsibility to the assailant than Italian women. These results are interpreted in terms of the importance attributed to family honour in the three countries and their differences in social organisation and gender roles.     

Influences of Fertility Status on Risky Driving Behaviour

The effects of hormones on human behaviour have been extensively studied, but little attention has been paid to the influence of ovarian hormones on risky driving. Twenty‐five normally cycling women took part in three sessions, including an ovulatory phase estimation session and two experimental sessions: high vs low fertile phases. These two phases were monitored through a urine‐based luteinizing hormone predictor test. In the two experimental sessions, participants were administered the Driving Behaviour Questionnaire and the Vienna Risk‐Taking Test. Results showed that women are more risk‐averse in their driving behaviour during their high‐fertile phase. The influence of hormonal fluctuations on self‐perception of risk attitude when driving was non‐significant. Findings are discussed from an evolutionary perspective.

Absolutely relative or relatively absolute: violations of value invariance in human decision making

Making decisions based on relative rather than absolute information processing is tied to choice optimality via the accumulation of evidence differences and to canonical neural processing via accumulation of evidence ratios. These theoretical frameworks predict invariance of decision latencies to absolute intensities that maintain differences and ratios, respectively. While information about the absolute values of the choice alternatives is not necessary for choosing the best alternative, it may nevertheless hold valuable information about the context of the decision. To test the sensitivity of human decision making to absolute values, we manipulated the intensities of brightness stimuli pairs while preserving either their differences or their ratios. Although asked to choose the brighter alternative relative to the other, participants responded faster to higher absolute values. Thus, our results provide empirical evidence for human sensitivity to task irrelevant absolute values indicating a hard-wired mechanism that precedes executive control. Computational investigations of several modelling architectures reveal two alternative accounts for this phenomenon, which combine absolute and relative processing. One account involves accumulation of differences with activation dependent processing noise and the other emerges from accumulation of absolute values subject to the temporal dynamics of lateral inhibition. The potential adaptive role of such choice mechanisms is discussed.     

Beyond Similarities: Cross-Gender and Cross-Orientation Best Friendship in a Sample of Sexual Minority and Heterosexual Young Adults

The research investigates differences between heterosexual (n?=?714) and lesbian and gay men (n?=?386) young adults regarding best friendship patterns, well-being, and social anxiety. Based on data from a paper-pencil survey of 1,100 Italian young adults aged 18 to 26, this study underlines the importance of the best friend in young adults’ psychological adjustment, highlighting patterns of friendship in heterosexual and lesbian and gay men young adults. Overall, the majority of participants declared that they had best friends; in the total sample, significant differences were found between women and men, and between lesbian/gay men participants and heterosexual young adults. Lesbian and gay men participants reported more cross-gender best friendships than heterosexual participants did, as well as more cross-orientation best friendships. Gender differences were found only with regards to cross-gender friendships: gay men reported more cross-gender friendships than lesbians did, while heterosexual females reported a higher percentage of cross-gender best friendship than heterosexual males did. MANOVA analysis, only in the gay and lesbian sample, showed the effect of gender, cross-gender, and cross-orientation on well-being and social anxiety. For the well-being dimension, gay men participants with female best friends reported higher scores. In terms of social anxiety, lesbian and gay young adults with cross-gender and cross-orientation best friends reported lower levels of social anxiety.     

Domestic horses (<Emphasis Type="Italic">Equus ferus caballus</Emphasis>) fail to intuitively reason about object properties like solidity and weight

From early infancy, humans reason about the external world in terms of identifiable, solid, cohesive objects persisting in space and time. This is one of the most fundamental human skills, which may be part of our innate conception of object properties. Although object permanence has been extensively studied across a variety of taxa, little is known about how non-human animals reason about other object properties. In this study, we therefore tested how domestic horses (Equus ferus caballus) intuitively reason about object properties like solidity and height, to locate hidden food. Horses were allowed to look for a food reward behind two opaque screens, only one of which had either the proper height or inclination to hide food rewards. Our results suggest that horses could not intuitively reason about physical object properties, but rather learned to select the screen with the proper height or inclination from the second set of 5 trials.     

Questions,Presuppositions and Fallacies

In this paper I focus on the fallacy known as Complex Question or Many Questions. After a brief introduction, in Sect. 2 I highlight its pragmatic dimension, and in Sect. 3 its dialectical dimension. In Sect. 4 I present two accounts of this fallacy developed in argumentation theory, Douglas Walton’s and the Pragma-Dialectics’, which have resources to capture both its pragmatic and its dialectical nature. However, these accounts are unsatisfactory for various reasons. In Sect. 5 I focus on the pragmatic dimension of the fallacy and I suggest amendments to the accounts mentioned drawing on the study of the phenomenon of presupposition in theoretical pragmatics. I argue that the central notion in the definition of the fallacy is that of an informative presupposition. In Sect. 6 I focus on the dialectical dimension of the fallacy. This dimension needs to be explicitly acknowledged in the definition of the fallacy in order to distinguish it from a different, non-dialectical, fallacious argumentative move involving presuppositions.

     

Tailoring Gratitude Interventions. How and for Whom Do They Work? The Potential Mediating Role of Reward Processing and the Moderating Role of Childhood Adversity and Trait Gratitude

Outcomes of gratitude interventions are encouraging, but inconsistent across studies. In addition, both mechanisms of change and effect modifiers for these interventions are largely unknown. Recent data point toward potential candidates and suggest reward processing may be a promising mechanism underlying these interventions, while childhood adversity (CA) and trait gratitude may impact on them. However, existing research aimed at investigating these hypotheses is scarce. Building on these, we examined the effectiveness of a gratitude intervention for decreasing depressive symptoms and negative affect and increasing positive affect. We also investigated changes in reward processing following intervention and explored differences in adherence and drop-out between groups. Finally, we investigated the moderating role of CA and trait gratitude.

Participants (N=237, ages between 18–56) were randomly allocated to a gratitude or active control condition (14 days). Following intervention, findings indicated a significant decrease in depressive symptoms and negative affect in both conditions. While positive affect remained stable, a significant time effect emerged for reward processing. CA severity, but not multiplicity, moderated the effectiveness of the intervention, adherence and drop-out. Trait gratitude moderated the effectiveness of the gratitude intervention only on depressive symptoms.

Gratitude interventions may not be the best fit for everyone. Thus, we recommend tailoring interventions, especially in individuals reporting a history of severe CA.
