(2013). Legal idioms: a framework for evidential reasoning. Argument & Computation: Vol. 4, Formal Models of Reasoning in Cognitive Psychology, pp. 46-63. doi: 10.1080/19462166.2012.682656.

Bayesian models of legal arguments generally aim to produce a single integrated model, combining each of the legal arguments under consideration. This combined approach implicitly assumes that variables and their relationships can be represented without any contradiction or misalignment, and in a way that makes sense with respect to the competing argument narratives. This paper describes a novel approach to compare and ‘average’ Bayesian models of legal arguments that have been built independently and with no attempt to make them consistent (...) in terms of variables, causal assumptions or parameterization. The approach involves assessing whether competing models of legal arguments are explained or predict facts uncovered before or during the trial process. Those models that are more heavily disconfirmed by the facts are given lower weight, as model plausibility measures, in the Bayesian model comparison and averaging framework adopted. In this way a plurality of arguments is allowed yet a single judgement based on all arguments is possible and rational. (shrink)

An extensive literature has demonstrated that encoding information in a self-referential manner enhances subsequent memory performance. This ‘self-reference effect’ is generally elicited in paradigms that require participants to evaluate the self-descriptiveness of personality characteristics. Extending work of this kind, the current research explored the possibility that explicit evaluative processing is not a necessary precondition for the emergence of this effect. Rather, responses to self cues may enhance item encoding even in the absence of explicit evaluative instructions. We explored this hypothesis (...) by testing memory for items encoded in either an evaluative or relational context. The relational context was achieved by requesting participants to report the spatial relationship between target stimuli, and visual or verbal referent cues. The results revealed a self-referent memory advantage, regardless of the encoding context or triggering cue. The theoretical implications of these findings are considered. (shrink)

We introduce and consider the inner-model reflection principle, which asserts that whenever a statement \varphi(a) in the first-order language of set theory is true in the set-theoretic universe V, then it is also true in a proper inner model W \subset A. A stronger principle, the ground-model reflection principle, asserts that any such \varphi(a) true in V is also true in some non-trivial ground model of the universe with respect to set forcing. These principles each express a form of width (...) reflection in contrast to the usual height reflection of the Lévy–Montague reflection theorem. They are each equiconsistent with ZFC and indeed \Pi_2-conservative over ZFC, being forceable by class forcing while preserving any desired rank-initial segment of the universe. Furthermore, the inner-model reflection principle is a consequence of the existence of sufficient large cardinals, and lightface formulations of the reflection principles follow from the maximality principle MP and from the inner-model hypothesis IMH. We also consider some questions concerning the expressibility of the principles. (shrink)

This article is an attempt to understand ethical theory not just as a set of well-developed philosophical perspectives but as a range of moral capacities that human beings more or less grow into over the course of their lives. To this end, we explore the connection between formal ethical theories and stage developmental psychologies, showing how individuals mature morally, regarding their duties, responsibilities, ideals, goals, values, and interests. The primary method is to extract from the writings of Kohlberg and his (...) students the cues that help to flesh out a developmental picture of a wide range of ethical perspectives. Thus, developmental psychology benefits from gaining a broader understanding of “morality” and “ethics,” and ethical theory benefits from a richer understanding of how moral maturity arises from youthful beginnings in juvenile and adolescent thinking. Results of this study offer insight into the difficulty of teaching ethics and a refined ability to assess moral maturity in business activity. (shrink)

Spirituality is an undeniable human need and is thus the subject of increasing interest among management scholars and practitioners. In this article, we propose using archetypal psychology as a framework for understanding the human need for spirituality more clearly because it provides important insights into spirituality and organizational life. Because most spiritual needs reside in the deepest aspects of the self, an archetypal approach helps us recognize not only that we have spiritual needs but also why we have them. We (...) present three common archetypes and their implications in a management context. That is followed by an application of the archetypal approach to some of the more spiritually corrosive aspects of organizational life and a discussion of the implicationsof archetypes as a source of motivation.

Advances in medical capability should be accompanied by discussion of their ethical implications. In the military medical context there is a growing interest in developing prophylactic interventions that will mitigate the effects of trauma and improve survival. The ethics of this novel capability are currently unexplored. This paper describes the concept of trauma prophylaxis and outlines some of the ethical issues that need to be considered, including within concept development, research and implementation. Trauma prophylaxis can be divided into interventions that (...) do not and those that do have medical enhancement as an unintended side effect of their prophylactic action. We conclude that type 1 interventions have much in common with established military medical prophylaxis, and the potentially enhancing qualities of type 2 interventions raise different issues. We welcome further debate on both interventions. (shrink)

It is standard in set theory to assume that Cantor's Theorem establishes that the continuum is an uncountable set. A challenge for this position comes from the observation that through forcing one can collapse any cardinal to the countable and that the continuum can be made arbitrarily large. In this paper, we present a different take on the relationship between Cantor's Theorem and extensions of universes, arguing that they can be seen as showing that every set is countable and that (...) the continuum is a proper class. We examine several principles based on maximality considerations in this framework, and show how some (namely Ordinal Inner Model Hypotheses) enable us to incorporate standard set theories (including ZFC with large cardinals added). We conclude that the systems considered raise questions concerning the foundational purposes of set theory. (shrink)

Previous studies show that reading sentences about actions leads to specific motor activity associated with actually performing those actions. We investigate how sign language input may modulate motor activation, using British Sign Language sentences, some of which explicitly encode direction of motion, versus written English, where motion is only implied. We find no evidence of action simulation in BSL comprehension, but we find effects of action simulation in comprehension of written English sentences by deaf native BSL signers. These results provide (...) constraints on the nature of mental simulations involved in comprehending action sentences referring to transfer events, suggesting that the richer contextual information provided by BSL sentences versus written or spoken English may reduce the need for action simulation in comprehension, at least when the event described does not map completely onto the signer's own body.

In response to recent corporate ethical and financial disasters there has been increased pressure on business schools to improve their teaching of corporate ethics. Accreditation bodies, such as the Association to Advance Collegiate Schools of Business (AACSB), now require member institutions to develop the ethical awareness of business students, either through a dedicated subject or an integrated coverage of ethics across the curriculum. This paper describes an institutional approach to the incorporation of a comprehensive multi-disciplinary ethics framework into the business (...) curriculum. We discuss important implications for the assessment of ethics within institutional assurance practices, and address critical issues related to the support of academics whenrequired to incorporate new ethics material within their subject which may be outside their field of expertise. As an example, the successful application of the framework within the marketing discipline is presented and discussed. (shrink)

Onora O’Neill is one of the foremost moral philosophers writing today. Her work on ethics and bioethics, political philosophy and the philosophy of Kant is extremely influential. Her landmark Reith Lectures on trust did much to establish the subject not only on the philosophical and political agenda but in the world of media, business and law more widely. Reading Onora O’Neill is the first book to examine and critically appraise the work of this important thinker. It includes specially commissioned chapters (...) by leading international philosophers in ethics, Kantian philosophy and political philosophy. The following aspects of O’Neill’s work are examined: global justice Kant the ethics of the family bioethics consent trust. Featuring a substantial reply to her critics at the end of the book, Reading Onora O’Neill is essential reading for students and scholars of ethics and political philosophy. (shrink)

We prove that the set of properties describable by a uniform sequence of first-order sentences using at most k + 1 distinct variables is exactly equal to the set of properties checkable by a Turing machine in DSPACE[n k ] (where n is the size of the universe). This set is also equal to the set of properties describable using an iterative definition for a finite set of relations of arity k. This is a refinement of the theorem PSPACE = (...) VAR[O[1]] [8]. We suggest some directions for exploiting this result to derive trade-offs between the number of variables and the quantifier depth in descriptive complexity. (shrink)

Set-theoretic and category-theoretic foundations represent different perspectives on mathematical subject matter. In particular, category-theoretic language focusses on properties that can be determined up to isomorphism within a category, whereas set theory admits of properties determined by the internal structure of the membership relation. Various objections have been raised against this aspect of set theory in the category-theoretic literature. In this article, we advocate a methodological pluralism concerning the two foundational languages, and provide a theory that fruitfully interrelates a `structural' perspective (...) to a set-theoretic one. We present a set-theoretic system that is able to talk about structures more naturally, and argue that it provides an important perspective on plausibly structural properties such as cardinality. We conclude the language of set theory can provide useful information about the notion of mathematical structure. (shrink)

Of the future technologies arising from the Human Genome Project, pharmacogenomics will probably be the first to have a widespread impact on the everyday practice of medicine. This technology offers great benefits but also presents some difficult ethical challenges. This paper explains what pharmacogenomics is and examines three of the issues that it raises: orphan populations, the use of ethnicity in drug trials, and potential obstacles to informed consent for genetic testing.

The Human Genome Project has raised many issues regarding the contributions of genetics to a variety of diseases and societal conditions. With genetic testing now easily conducted with lowered costs in nonmedical domains, a variety of privacy issues must be considered. Such testing will result in the loss of significant privacy rights for the individual. Society must now consider such issues as the ownership of genetic data, confidentiality rights to such information, limits placed on genetic screening, and legislation to control (...) genetic testing and its applications. There is often a conflict between individual rights to privacy and the need for societal protection. (shrink)

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory , thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A (...) subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition. (shrink)

Is copyright a property right? Common law and civil law jurists have debated that issue for over three centuries. It remains at the heart of battles over copyright’s scope and duration today, even if its import lies principally in the rhetorical force of labeling a right as "property," not in any doctrinal consequence flowing directly from that label. In parallel to their common law and civil law counterparts, presentday rabbinic jurists engage in lively debate about whether Jewish law recognizes copyright (...) as a property right. And, as in secular law but for different reasons, that issue has significant repercussions in Jewish law. As discussed in rabbinic court decisions and writings, whether Jewish law accords authors a right of ownership in their works impacts such issues as whether it is permissible, without license from the author or publisher, to copy and distribute software and sound recordings, perform music in wedding halls, make copies for private and classroom use, and download songs from the Internet. There are numerous, and at times profound, differences in the terminology, form of argument, doctrinal specifics, and overarching legal framework of Jewish and secular law. Nonetheless, the arguments within the Jewish law debate have some intriguing parallels with those of secular copyright law. In fact, one finds the direct, if largely unstated, influence of secular copyright just below the surface in the debate in Jewish law about whether copyright is property. (shrink)

As a result of the publicly funded Human Genome Project (HGP), and an increasing number of private enterprises, a new form of eugenic theory and practice has emerged, differing from previous manifestations. Genetic testing has become a consumer service that may now be purchased at greatly reduced cost. While the old eugenics was pseudoscientific, the new eugenics is firmly based on DNA research. While the old eugenics focused on societal measures against the individual, the new eugenics emphasizes the family as (...) a control agent. Eugenics is now voluntary, with the promise of abortion for those afraid of producing genetically damaged children. The ethical concepts of beneficence, avoidance of maleficence, autonomy, and equity are discussed in terms of aspects of the HGP. One major issue is the need for an ethical system available to health consumers that will empower them and assist in their biogenic decisions. “The concentration on the genes implicated in cancer is only a special case of a general genomania (emphasis added) that surfaces in ... the weekly announcements in The New York Times of the location of yet another gene for another disease. The revealing rhetoric of this publicity is always the same; only the blanks need to be filled in: ‘It was announced today by scientists at [Harvard, Vanderbilt, Stanford] Medical School that a gene responsible for [some, many, a common form of] [schizophrenia, Alzheimer’s, arteriosclerosis, prostate cancer] has been located and its DNA sequence determined. This exciting research, say scientists, is the first step in what may eventually turn out to be a possible cure for this disease.’”. (shrink)
