Poor nutrition habits have been reported in the childcare setting. While the literature advocates the need to carry out ‘Voice of the Child’ research, few studies have explored this methodology with regard to children and food, in particular in the pre-school setting. This article aims to outline the ethical issues raised by a research ethics committee and to discuss the impact of these issues on a study that hoped to determine the food perceptions of children (aged three to four years) (...) within an ongoing nutrition and lifestyle pre-school project in Ireland. Ethical approval was granted for this study but only upon the clarification of two aspects: that only hedonic symbols previously used in the literature could be included in the study; and that parental consent be obtained from both parents of each child. Children were shown food pictures and asked to use the hedonic symbols to answer questions posed to them on the food. Owing to the ethical constraints imposed by the requirement for two-parent consent, seven children, from a potential sample of 85, were eligible to partake in the study. These children did not seem to understand the hedonic symbols recommended for use by the ethics committee, therefore preventing the collection of in-depth qualitative data. The ethical constraints placed on this study impacted on both its design and its methodology and are discussed in relation to national and international ethical guidance and legislation. Future research with children regarding food choice must balance the need for strict ethical standards with the need to explore children’s views on this subject. (shrink)

In a criminal trial, a judge or jury needs to reason about what happened based on the available evidence, often including statistical evidence. While a probabilistic approach is suitable for analysing the statistical evidence, a judge or jury may be more inclined to use a narrative or argumentative approach when considering the case as a whole. In this paper we propose a combination of two approaches, combining Bayesian networks with scenarios. Whereas a Bayesian network is a popular tool for analysing (...) parts of a case, constructing and understanding a network for an entire case is not straightforward. We propose an explanation method for understanding a Bayesian network in terms of scenarios. This method builds on a previously proposed construction method, which we slightly adapt with the use of scenario schemes for the purpose of explaining. The resulting structure is explained in terms of scenarios, scenario quality and evidential support. A probabilistic interpretation of scenario quality is provided using the concept of scenario schemes. Finally, the method is evaluated by means of a case study. (shrink)

In a criminal trial, evidence is used to draw conclusions about what happened concerning a supposed crime. Traditionally, the three main approaches to modeling reasoning with evidence are argumentative, narrative and probabilistic approaches. Integrating these three approaches could arguably enhance the communication between an expert and a judge or jury. In previous work, techniques were proposed to represent narratives in a Bayesian network and to use narratives as a basis for systematizing the construction of a Bayesian network for a legal (...) case. In this paper, these techniques are combined to form a design method for constructing a Bayesian network based on narratives. This design method is evaluated by means of an extensive case study concerning the notorious Dutch case of the Anjum murders. (shrink)

According to the Spatial Quantity Association of Response Codes (SQUARC), people hold a mental association between horizontal position and quantity (lower quantities left, higher quantities right). While a large body of research has explored this effect for response speed and judgment accuracy, the affective downstream consequences of the SQUARC remain unexplored. Aiming to address this gap, the present two experiments (pre-registered, total N = 521) investigated whether stimulus arrangements that are compatible with the SQUARC for luminance are affectively preferred to (...) stimulus arrangements that are incompatible. SQUARC-compatible square arrangements (dark-left, bright-right) were preferred over SQUARC-incompatible square arrangements (dark-right, bright-left). The preference for SQUARC compatibility was not moderated by the horizontal orientation of the response scale. Our results confirm the direction of the spatial-luminance association and provide initial support that the cognitive processing of SQUARC compatibility is hedonically marked and appears sufficient to impact affective evaluations.

Souzy Dracopoulou , Ethics and values in health care management.

This paper explores why respondents to a telephone public-opinion survey often give reasons for answering as they do, even though reason-giving is neither required nor encouraged and it is difficult to see the reasons as attempts to deal with disagreement. We find that respondents give reasons for the policy claims they make in their answers three times as frequently as they give reasons for value or factual claims, that their reasons tend to involve appeals to personal experience, and that they (...) often talk about their thought processes, especially when the evidentiary stakes are high. We then explore several ways of explaining these findings. We suggest that one useful approach is to see the reason-giving in the survey interviews as deliberative, reflexive argumentation of the sort described as `critical thinking. We further suggest that the reason such argumentation is often conducted out loud in the interviews, rather than internally, is that it functions in the service of rhetorical ethos, in particular the need to display the fact that one is human, with human autonomy and agency. Doing this may be particularly important in contexts such as anonymous survey interviews in which people are at risk of being treated like machines. (shrink)

Research on the Spatial Quantity Association of Response Codes (SQUARC) has documented associations between spatial position and mental representations of quantity. Large quantities are associated with right and top, small quantities are associated with left and bottom. Resulting compatibility effects have largely been documented for response speed and judgment accuracy. Recently, employing luminance as quantity, Löffler et al. (2022) generalised such SQUARC compatibility effects to affective judgments, showing that horizontally SQUARC-compatible stimulus arrangements (i.e. bright on the right, dark on the (...) left side) are liked more than SQUARC-incompatible arrangements. The present Experiment 1 (N = 296) replicated this horizontal compatibility effect, dz =.18, and generalised it to vertical luminance SQUARC compatibility (i.e. bright on the top, dark on the bottom), dz =.22. Experiments 2a-b (total N = 259; Experiment 2b preregistered) employed stimulus arrangements tilted by 45° to manipulate horizontal and vertical (in)compatibility simultaneously within the same stimulus, finding robust horizontal compatibility effects, but mixed evidence regarding vertical compatibility.

Review of Substance and Essence in Aristotle: an Interpretation of Metaphysics VII-IX, by Charlotte Witt (Cornell University Press: 1989).

Problematic substance use (PSU) among nurses has wide‐ranging adverse implications. A critical integrative literature review was conducted with an emphasis on building knowledge regarding the influence of structural factors within nurses' professional environments on nurses with PSU. Five thematic categories emerged: (i) access, (ii) stress, and (iii) attitudes as contributory factors, (iv) treatment policies for nurses with PSU, and (v) the culture of the nursing profession. Conclusions were that an overemphasis on individual culpability and failing predominates in the literature and (...) that crucial knowledge gaps exist regarding the influence of structural factors on driving and shaping nurses' substance use.

Three standard psychometric tests were administered to parents who volunteered their children for a randomised, double-blind placebo-controlled trial of a new asthma drug and to a control group of parents whose children were eligible for the trial but had declined the invitation. The trial took place at a children's hospital in Australia. The subjects comprised 68 parents who had volunteered their children and 42 who had not, a participation rate of 94 per cent and 70 per cent, respectively. The responses (...) of these parents to the Gordon Survey of Interpersonal Values Questionnaire, the Coopersmith Self-Esteem Inventory and the Cattell Sixteen Personality Factor Questionnaire were analysed by computer. There was a marked difference between the psychological profiles of the two groups of parents. Volunteering parents put more value on benevolence while non-volunteering parents were more concerned with power and prestige. The self-esteem of volunteering parents was much lower than that of non-volunteering parents. Finally, volunteering parents were more introverted, exhibited greater anxiety and low supergo, while non-volunteering parents appeared to have greater social confidence and emotional stability. Since an individual's values, self-esteem and personality may be important antecedents of behaviour, these findings suggest that parents who volunteer their children for clinical research are not only socially disadvantaged and emotionally vulnerable, but may also be psychologically predisposed to volunteering. Furthermore, these findings provide evidence for the existence of a psychosocial 'filter' effect of the informed consent procedure, which may be discouraging the better educated, more privileged and psychologically resilient members of society from participation as research subjects.

In Pro Murena, Cicero argues that Cato’s rigid philosophical comportment to politics reflects a mistaken understanding both of philosophy and of politics. By implication, he suggests that there is an approach to philosophy that is compatible with political leadership. Specifically, he argues that a thoroughgoing commitment to the philosophy of the Platonic Academy (i.e., Academic Philosophy) is entirely compatible with a thoroughgoing commitment to political leadership in the late Roman Republic. This essay looks at the most famous treatment of philosophical (...) leadership in the Platonic corpus, the philosopher ruler of the Republic, and asks to what extent Cicero’s depiction of politics and philosophy is consonant with that account.

THE MOST SACRED FREEDOM includes eight essays that were first presented at the 2014 A.V. Elliott Conference on Great Books and Ideas, the seventh annual conference sponsored by Mercer Universitys Thomas C. and Ramona E. McDonald Center for Americas Founding Principles. Together, these essays explore the great principle of religious liberty by charting its development in the Western tradition and reconsidering its place at Americas founding. The book begins with a comparison between the flood accounts in Genesis and the Mesopotamian (...) Atra-Has's and advances all the way to the 2014 Supreme Court case Burwell v. Hobby Lobby. The intervening chapters examine the contributions of figures such as Emperor Julian, Roger Williams, Cecilius Calvert, John Locke, Jean-Jacques Rousseau, and the American Founders. Contributors to the volume are Steven Grosby, Jeremiah H. Russell, Maura Jane Farrelly, Daniel Cullen, John Witte, Jr., Scott Yenor, David Ramsey, and Michael Novak. (shrink)

Plato's most magisterial dialogue, the Republic, takes up the question "what is justice," and its central image is an imaginary city constructed in speech designed to aid in this inquiry. In Book V of the Republic, Socrates tells his interlocutors that they have completed the "Male Drama," of the city in speech and that it is now time for them to take up the "Female." The "Female Drama" is Socrates name for the action of the central books of the Republic: (...) V-VII. Much has been made of what this transition in the Republic signifies for political questions. The Republic is not only concerned with politics or political justice, however. Like all of the images and arguments in the Republic, the Female Drama of the city in speech has meaning both for political and individual justice, but there has been no systematic inquiry into the central books of the Republic for their meaning for individual justice. That is the ambition of this book. On the level of moral psychology, Thomas argues that while the Male Drama of Books II-IV presents images of fully formed versions of the psychological activities that come together to define justice in a human life, the Female Drama explores the modes of potentiality and becoming necessary for those psychological activities to come into being. More specifically, Books V-VII explore the three modes of potentiality necessary for the development of justice: genesis, trophe, and paideia. (shrink)

Nurses’ experiences in, and the overall effectiveness of, widely used alternative‐to‐discipline programs to manage nurses’ substance‐use problems have not been adequately scrutinized. We uncovered the conflicted official and experiential ways of knowing one such alternative‐to‐discipline program in a Canadian province. We explicated this conflict through an institutional ethnography analysis. Ethnographic data from interviews with 12 nurses who were enrolled in an alternative‐to‐discipline treatment program and three program administrators, as well as institutional texts, were analyzed to explore how institutional practices and (...) power relations co‐ordinated and managed nurses’ experiences. Analysis revealed the acritical acceptance of a standardized program not based on current norms of practice. Potential and actual conflicts of interest, power imbalances, and prevailing corporate interests were rife. Nurses were not afforded the same rights to quality ethical health care as other citizens. ‘Expert’ physicians’ knowledge was privileged while nurses’ knowledge was subordinated. Conclusions were that regulatory bodies cannot rely on the taken‐for‐granted standardized treatment model in widespread use. Individualized treatment alternatives reflecting current, scientific evidence must be offered to nurses, and nurses’ knowledge, expertise, and experiences need to be included in decision‐making processes in these programs.

Based on the 2019 A.V. Elliott Conference on Great Books and Ideas at Mercer University, eleven scholars take up some of the complex questions that emerge when one considers carefully how Plato presents democracy and liberty in the dialogues, particularly in terms of the threats they seem to pose to justice and philosophy. When Athens lost the Peloponnesian War, the Athenian people also lost their democratic constitution for a brief but brutal time. Plato wrote his dialogues and founded his Academy (...) in the early days of Athens's newly restored democratic regime, the regime that executed Socrates. But, he set most of the dialogues in the days leading up to Athens's downfall. Plato presents Socrates as so deeply committed to Athens that he would not consider living anywhere else, even when the Athenians intend to execute him. The authors whose essays are collected in this volume explore these tensions deeply and with great attention to the subtleties and complexities of Plato's texts. (shrink)

It is conventional to argue that the city-soul analogy of Plato’s Republic dominates Books ii through iv and viii through x but is absent in Books v through vii. We argue that the analogy remains operative in Books v through vii and that its role there, especially as it is played out in the motif of the three waves, illuminates its function in the dialogue as a whole, particularly with respect to the questions: What are the natural dispositions of soul (...) necessary for philosophy? What are the necessary and sufficient conditions for philosophical education? (shrink)

Aristotle's defense of Dunamis -- Power and potentiality -- Rational and nonrational powers -- The priority of actuality -- Ontological hierarchy, normativity, and gender.

Michel de Montaigne begins his magisterial ESSAIS by telling his readers that he, himself, is the matter of his book. He says that he has written himself so that after death he could remain in the world with those who knew and loved him. Montaignes intimate project, meant to be read by friends, has emerged as one of the most surprising and compelling accounts of the human condition ever written. Although Montaigne famously retired from public life to write his essais, (...) neither his concerns nor the activities recounted in ESSAIS is purely private. This volume of essays, based on papers presented at The A.V. Elliott Conference for Great Books and Ideas sponsored by Mercer Universitys McDonald Center for Americas Founding Principles, focuses on the outward oriented political philosophy of Montaigne. Contributors include Ann Hartle, Daniel Cullen, Christine Henderson, Eduardo Velasquez, Kevin Honeycutt, and Christopher Edelman. (shrink)

The prospect of using cell-based interventions to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such changes, although perhaps remote, is cause (...) for concern and careful ethical analysis. Both to enable better informed consent in the future and as an end in itself, we argue that early human trials of CBIs for neurological conditions must monitor subjects for changes in cognition, mood, and behavior; further, we recommend concrete steps for that monitoring. Such steps will help better characterize the potential risks and benefits of CBIs as they are tested and potentially used for treatment. (shrink)

With Hegel’s metaphysics attracting renewed attention, it is time to address a long-standing criticism: Scholars from Marx to Popper and Habermas have worried that Hegel’s metaphysics has anti-individualist and authoritarian implications, which are particularly pronounced in his Philosophy of History, since Hegel identifies historical progress with reason imposing itself on individuals. Rather than proposing an alternative non-metaphysical conception of reason, as Pippin or Brandom have done, this article argues that critics are broadly right in their metaphysical reading of Hegel’s central (...) concepts. However, they are mistaken about what Hegel’s approach entails, when one examines the specific types of states discussed by the philosopher in his Philosophy of History. Even on a traditional metaphysical reading, Hegel is not only non-authoritarian; he also makes a powerful argument concerning freedom, whereupon the freest society involves collective oversight and the shaping of social structures so as to ensure that they benefit everybody.

Food media have become a formidable part of adolescents’ food environments. This study sought to explore how and why adolescents use food media by focusing on selectivity and motives for consumption. We conducted in-depth, semi-structured interviews with 31 Flemish adolescents aged 12 to 16. Food media were both incidentally consumed and selectively sought for education, social utility, and entertainment. The levels of selectivity and motives for consumption varied among the different food media platforms. Incidental consumption was more prevalent with TV (...) cooking shows compared to online food media. The dominant motives for TV cooking show consumption were companionship and entertainment, while online food media were used for a more diverse range of motives dominated by information/inspiration and social interaction. Some participants consumed food media to get motivation and inspiration to improve health and fitness while others consumed food media to watch appetizing and aesthetically pleasing food content. The social environment in the form of friends and family as well as existing food preferences were dominant psychosocial factors for both traditional and online food media use. Future research is warranted to explore how incidental exposure and the identified motives for use relate to food media effects. (shrink)

The idea of the inner is central to our conception of a person and is at the heart of all interaction. But how should we understand this concept, and what do we mean when we wonder what is going on inside our heads? This accessible and non-technical guide to Wittgenstein provides insight into his work in this area and on the problem of the inner. Using Wittgenstein's recently published writings on the philosophy of psychology, together with unpublished material, Paul (...) class='Hi'>Johnston presents a thorough account of a subject that was central to Wittgenstein's later work. He shows that Wittgenstein's arguments involve a radical re-thinking of our understanding of the inner and present a challenge to contemporary views which has yet to be fully appreciated or understood. Wittgenstein demonstrates how a Wittgensteinian approach can dissolve age-old problems about the nature of consciousness and the relationship between the mind, the body, and the soul. The resulting picture of the inner, with its stress on the crucial role of language, sheds light on the direction of Wittgenstein's work and presents a stimulating and controversial alternative to more fashionable positions on the subject.

Many interpreters argue that irrational acts of exchange can count as rational and civic-minded for Hegel—even though, admittedly, the persons who are exchanging their property are usually unaware of this fact. While I do not want to deny that property exchange can count as rational in terms of ‘mutual recognition’ as interpreters claim, this proposition raises an important question: What about the irrationality and arbitrariness that individuals as property owners and persons consciously enjoy? Are they mere vestiges of nature in (...) Hegel’s system, or do they constitute a simple yet valid form of freedom that is not only a part of Hegel’s rational system of right, but its necessary starting point? I will argue the latter: The arbitrary, purely egoist self-definition of property owners is the simplest possible type of freedom for Hegel, which he dissects in order to show how the very arbitrary self-definition implicitly relies on an identity between persons, and hence foreshadows the more social forms of freedom Hegel will discuss later in his book. I make this argument by highlighting Hegel’s references to his discussion of atoms and freedom in his Logic of Being. (shrink)

While Hegel's metaphysics was long reviled, it has garnered more interest in recent years, with even the so-called non-metaphysical Hegelians starting to explicitly discuss Hegel’s metaphysical commitments. This brings up the old question: what are the social-philosophical implications of Hegel’s metaphysics? This chapter provides a unique answer to this question by contrasting the former non-metaphysical reading (as developed by Robert Pippin) with a traditional way of interpreting Hegel’s metaphysics and social philosophy, whose lineage includes not Wittgenstein, Sellars, or Brandom, but (...) rather Schelling, Marx, and Adorno. After discussing the two varieties of metaphysics (Sections 1–3), I will argue that a traditional metaphysical Hegel is more realist when it comes to assessing the power of social structures (Section 4), focused on structural freedom rather than agency (Sections 5 and 6), and more empowering for and lenient towards individuals who can make their interests count and are free to be irrational and egoist (Section 7).

In this paper we present two compatible hypotheses to explain interest in celebrity gossip. The Learning Hypothesis explains interest in celebrity gossip as a by-product of an evolved mechanism useful for acquiring fitness-relevant survival information. The Parasocial Hypothesis sees celebrity gossip as a diversion of this mechanism, which leads individuals to misperceive celebrities as people who are part of their social network. Using two preliminary studies, we tested our predictions. In a survey with 838 respondents and in-depth interviews with 103 (...) individuals, we investigated how interest in celebrity gossip was related to several dimensions of the participants’ social lives. In support of the Learning Hypothesis, age proved to be a strong predictor of interest in celebrities. In partial support of the Parasocial Hypothesis, media exposure, but not social isolation, was a strong predictor of interest in celebrities. The preliminary results support both theories, indicate that across our life span celebrities move from being teachers to being friends, and open up a list of future research opportunities. (shrink)

This article discusses an interpretation of Kant's conception of transcendental subjectivity, which manages to avoid many of the concerns that have been raised by analytic interpreters over this doctrine. It is an interpretation put forward by selected C19 and early C20 neo-Kantian writers. The article starts out by offering a neo-Kantian interpretation of the object as something that is constituted by the categories and that serves as a standard of truth within a theory of judgment. The second part explicates transcendental (...) subjectivity as the system of categories, which is self-referential and constitutes objects, in order to then evaluate this conception by means of a comparison with Hegel's absolute subject. Rather than delineating the differences between neo-Kantian writers, the article systematically expounds a shared project, which consists in providing the ultimate foundation for judgments by means of an anti-psychologist and non-metaphysical interpretation of transcendental subjectivity.

Mitochondria can change their shape from discrete isolated organelles to a large continuous reticulum. The cellular advantages underlying these fused networks are still incompletely understood. In this paper, we describe and compare hypotheses regarding the function of mitochondrial networks. We use mathematical and physical tools both to investigate existing hypotheses and to generate new ones, and we suggest experimental and modelling strategies. Among the novel insights we underline from this work are the possibilities that (i) selective mitophagy is not required (...) for quality control because selective fusion is sufficient; (ii) increased connectivity may have non‐linear effects on the diffusion rate of proteins; and (iii) fused networks can act to dampen biochemical fluctuations. We hope to convey to the reader that quantitative approaches can drive advances in the understanding of the physiological advantage of these morphological changes. (shrink)

The neo-Kantian Hermann Cohen is famously anti-empiricist in that he denies that sensations can make a definable contribution to knowledge. However, in the second edition of Kant’s Theory of Experience (1885), Cohen considers a proposition that contrasts with both his other work and that of his followers: a Kantian who studies scientific claims to truth—and the grounds on which they are made—cannot limit himself to studying mathematics and logical principles, but needs to also investigate underlying presuppositions about the empirical element (...) of science. Due to his subjectivist approach, Cohen argues, Kant not only failed to explain how scientific observation and experiments are possible, but also misconceived the role of the ideas, particularly the idea of a system of nature.

Reproduction has entered a new ice age: the ability to cryopreserve reproductive cells, tissue and embryos are fundamentally changing our understanding of what it means to be a reproductive citizen. This book explores the ways in which opinions of desirable reproductive futures are feared or are being welcomed by advances in freezing technologies, with the authors situating their discussions of cryo-fertility primarily within the Scandinavian region, asking: * How does cryopreservation help mobilize particular understandings of reproductive time, reproductive rights and (...) reproductive autonomy? * What values are embedded within Scandinavian laws that seek to regulate cryotechnologies? * How do men and women who freeze their gamets imagine the preservation of their material? -/- These questions demand a collaborative approach. The authors empirically cut across the areas of bioethics/law, practices/experiences and culture/commerce in order to pin down often comples and far-reaching answers. (shrink)

When people engage in conversation, they tailor their utterances to their conversational partners, whether these partners are other humans or computational systems. This tailoring, or adaptation to the partner takes place in all facets of human language use, and is based on a mental model or a user model of the conversational partner. Such adaptation has been shown to improve listeners' comprehension, their satisfaction with an interactive system, the efficiency with which they execute conversational tasks, and the likelihood of achieving (...) higher level goals such as changing the listener's beliefs and attitudes. We focus on one aspect of adaptation, namely the tailoring of the content of dialogue system utterances for the higher level processes of persuasion, argumentation and advice-giving. Our hypothesis is that algorithms that adapt content for these processes, according to a user model, will improve the usability, efficiency, and effectiveness of dialogue systems. We describe a multimodal dialogue system and algorithms for adaptive content selection based on multi-attribute decision theory. We demonstrate experimentally the improved efficacy of system responses through the use of user models to both tailor the content of system utterances and to manipulate their conciseness. (shrink)

In De Anima II.6, Aristotle divides the objects of perception into three kinds: “special perceptibles" (idia aisthêta) such as colours, sounds and flavours, which can be perceived in their own right by only one sense; “common perceptibles" (koina aisthêta) such as shapes, sizes and movements, which can be perceived in their own right by multiple senses; and “incidental perceptibles,” such as the son of Diares, which can be perceived only “incidentally” (kata sumbebêkos). In this paper, I examine this division of (...) perceptibles and consider what it amounts to. First, I argue that Aristotle’s distinction between perceiving something in its own right (kath' hauto) and perceiving it incidentally marks a causal distinction: what is perceived in its own right causes perception as such, whereas what is perceived incidentally coincides with what is perceived in its own right. Second, I argue that for Aristotle special perceptibles, unlike common perceptibles, belong to homogeneous bodies on account of their chemical composition. Finally, I explain the primacy Aristotle assigns to special perceptibles and his claim that perception of them alone is free from error. I conclude with some brief remarks on Aristotle and the primary/secondary quality distinction. (shrink)
