Data Trimming, Nuclear Emissions, and Climate Change

Ethics requires good science. Many scientists, government leaders, and industry representatives support tripling of global-nuclear-energy capacity on the grounds that nuclear fission is “carbon free” and “releases no greenhouse gases.” However, such claims are scientifically questionable (and thus likely to lead to ethically questionable energy choices) for at least 3 reasons. (i) They rely on trimming the data on nuclear greenhouse-gas emissions (GHGE), perhaps in part because flawed Kyoto Protocol conventions require no full nuclear-fuel-cycle assessment of carbon content. (ii) They underestimate nuclear-fuel-cycle releases by erroneously assuming that mostly high-grade uranium ore, with much lower emissions, is used. (iii) They inconsistently compare nuclear-related GHGE only to those from fossil fuels, rather than to those from the best GHG-avoiding energy technologies. Once scientists take account of (i)–(iii), it is possible to show that although the nuclear fuel cycle releases (per kWh) much fewer GHG than coal and oil, nevertheless it releases far more GHG than wind and solar-photovoltaic. Although there may be other, ethical, reasons to support nuclear tripling, reducing or avoiding GHG does not appear to be one of them.     

Understanding What’s Good for Us

The ancient question of what a good life consists in is currently the focus of intense debate. There are two aspects to this debate: the first concerns how the concept of a good life is to be understood; the second concerns what kinds of life fall within the extension of this concept. In this paper, I will attend only to the first, conceptual aspect and not to the second, substantive aspect. More precisely, I will address the preliminary, underlying question of how to understand what it is in general for something to be good for someone, from which an understanding of the more particular concept of a good life may be derived.

The protective identity: Evidence that mortality salience heightens the clarity and coherence of the self-concept

Research guided by terror management theory has shown that self-esteem provides a buffer against mortality concerns. The current research extends the theory to examine whether clarity and coherence in the structure of the self-concept serve a terror management function independent of enhancing self-esteem. Specifically, five studies tested whether mortality salience (MS) heightens diverse tendencies to clarify and integrate self-relevant knowledge, especially in individuals predisposed to seek structured knowledge. MS led high, but not low, structure-seeking participants to prefer coherent (Study 1) clearly-defined (Study 2), and simply organized (Study 3) conceptions of their personal characteristics. Also, MS led high structure-seeking participants to prefer causal coherence in recent experience (Study 4) and meaningful connections between past events and their current self (Study 5). Supporting the specificity of these effects on self-concept structuring, MS increased self-enhancement in Studies 1, 4, and 5 but these effects were not moderated by preference for structured knowledge.     

Claiming a moral minority, saccades help create a biased majority: Tracking eye movements to base rates in social predictions

How do people hold erroneous views about their own moral behavior? This study investigated the use of distributional information in self and social predictions by measuring eye movements to base rates. Across 15 scenarios, participants claimed moral superiority over a comparison peer by predicting that base rates would be less predictive of one’s own behaviors than a comparison peer’s. In support of the differential use of distributional information hypothesis, participants looked less often to base rate information when making self rather than social predictions. Eye movements mediated the relationship between target of the prediction and the strength of the relationship between base rates and behavioral likelihood estimates. Implications for self-deception in self and social judgment are discussed.     

Awareness of a gender stereotype,personal beliefs and self-perceptions regarding math ability: when boys do not surpass girls

The negative reputation of women in mathematics and its consequences on their self-perceptions have been extensively demonstrated. However, in France and other countries, the younger the students, the less pronounced these gender differences are. The focus of this study was to explore whether children of two age groups (fourth graders and seventh graders) are aware of a math-ability gender stereotype favorable to boys, and to determine their personal beliefs on mathematics ability. The link between this gender stereotype and self-perceptions was also examined. As expected, there was not a clear-cut awareness of a math-ability gender stereotype favorable to boys. More surprising, girls in both age groups and seventh-grade boys believed that girls do better than boys. Moreover, when their gender identity was made salient, the boys who believed in girl superiority perceived their own performance in mathematics as lower. The girls, on the other hand, regardless of their age and stereotype awareness or personal beliefs, perceived their performance in math as higher when their gender identity was made salient than when it was not.     

Qualified therapists’ experience of personal therapy

Recent work shows that the majority of therapists strongly value personal therapy for what it can bring to their professional practice, and for personal development. The aim of this study was to explore qualified therapists’ experiences of personal therapy. Of the 220 qualified therapists who were contacted via post and asked to take part in a questionnaire study, 48 returned the completed questionnaire, which consisted of a series of closed and open questions. Two‐thirds of respondents had engaged in personal therapy. The two most frequently cited reasons for engaging in personal therapy were personal growth and personal distress. Interpretative phenomenological analysis (IPA) identified two broad domains: impact on the person and impact on the professional. Results show that those surveyed recognised the value of personal therapy to themselves as a form of self‐care and personal development. Personal therapy was valued in professional practice as a form of experiential learning from being in the client role. The limitations of this research included a relatively low response rate, raising the question of whether those most likely to have had positive experiences of personal therapy were more likely to participate. Future research might deliberately seek to understand negative experiences of personal therapy. Other avenues for future research include the need to understand how experiences of therapy relate to gender, profession, and therapeutic orientation.     

Imagining human enhancement: whose future,which rationality?

This article critically evaluates bettering human life. Because this involves lives that do not exist yet, the article investigates human eugenics and enhancement through the social prism of ‘the imaginary’ (defined ‘as a set of assumptions and concepts for thinking and speaking about human enhancement and its future direction’) [1]. “Exploring basic assumptions underlying the idea of human enhancement” investigates underlying assumptions and claims for human enhancement. Firstly, human eugenics and enhancement entangles a factual as well as a normative claim about what improvement/betterment maybe constitutive of. Secondly, claims about what a better life is, is often a future orientated claim about whether certain kinds of life that do not exist yet should ever exist. Moral images of thought are introduced and how they work to make normative judgments about lives that do not exist. This implicates the moral problem of difference, where an image of a ‘better’ life—classically expressed in eugenics as a ‘superior’ and/or ‘normal’ life—necessarily entails inferiority and/or deviance from a norm. “Moral imagination in contemporary fiction and the history of old eugenics”, introduces moral images in history of eugenics and demonstrates how examples fall foul of the problem. “The new (liberal) eugenics and the moral image of therapy” examines progress in contemporary debates, the move from authoritarian to non-authoritarian eugenics (human enhancement), and how, to some extent, this has solved the problem of difference, through liberal defence of personal choice. “The heart of the eugenic issue” suggests that personal choice in liberal non-authoritarian eugenics is not immune to basic drive behind all eugenic arguments; desire as lack which is expressed as the continual dissatisfaction of not having our future expectations met.

Question answering from structured knowledge sources

We present an implemented approach for domain-restricted question answering from structured knowledge sources, based on robust semantic analysis in a hybrid NLP system architecture. We perform question interpretation and answer extraction in an architecture that builds on a lexical-conceptual structure for question interpretation, which is interfaced with domain-specific concepts and properties in a structured knowledge base. Question interpretation involves a limited amount of domain-specific inferences, and accounts for higher-level quantificational questions. Question interpretation and answer extraction are modular components that interact in clearly defined ways. We derive so-called proto queries from the linguistic representations, which provide partial constraints for answer extraction from the underlying knowledge sources. The search queries we construct from proto queries effectively compute minimal spanning trees from the underlying knowledge sources. Our approach naturally extends to multilingual question answering, and has been developed as a prototype system for two application domains: the domain of Nobel prize winners, and the domain of Language Technology, on the basis of the large ontology underlying the information portal LT World.
