Nondeterministic models of collective choice posit convergence among the outcomes of simple-majority decisions. The object of this research is to estimate the extent of convergence of majority choice under different procedural conditions. The paper reports results from a computer simulation of simple-majority decision making by committees. Simulation experiments generate distributions of majority-adopted proposals in two-dimensional space. These represent nondeterministic outcomes of majority choice by committees. The proposal distributions provide data for a quantitative evaluation of (...) class='Hi'>committee-choice procedures in respect to outcome convergence. Experiments were run under general conditions, and under conditions that restrict committee choice to several game-theoretic solution sets. The findings are that, compared to distributions of voter ideal points, majority-adopted proposals confined to the solution sets demonstrate different degrees of convergence. Second, endogenous agenda formation is a more important obstacle to convergence than the inherent instability of simple-majority rule. Third, if members maximize preferences in respect to agenda formation, a committee choice that approximates the central tendency of the distribution of voter preferences is unlikely. The conclusion is that the most effective way to increase the convergence of majority choice is to restrict the role of individual preferences in agenda formation: identification of proposals to be voted up or down by a committee.

“Poland 2050” Report is a publication of a distinctive sort. While the idea of producingthis report has a long history, it began to take shape about two years ago. It isbased on the two tenets. The first, raised at numerous conferences held in the past underthe auspices of the “Poland 2000 Plus” Committee, is the conviction that economicgrowth does not transpose automatically into societal (or more broadly “civilizational”)advancement. Indeed, the preliminary analysis has indicated that the two processes are,in fact, (...) divergent. While there have been convergent processes evident in Poland’s andthe EU’s economic domains, no such convergence is significantly evident in the case ofsocietal progress. This gave rise to the vision set forth in this Report, formulated as“minimizing Poland’s developmental gap with respect to the more advanced EU states.”The second tenet upon which this Report is based is even more important. Numerousanalyses carried out by the Committee indicate that quantitative changes cannot bepredicted four decades in advance with great likelihood. And so, we did not base ourReport on existing quantitative trends, but rather on analysis of the pathways that willmake it possible to minimize Poland’s developmental gap with respect to the advancedEU states. The Report also strives to highlight threats that exist in the social and “civilizational”sphere.The Report was based on the materials published in the three volumes of the publicationWizja przyszłości Polski – Studia i Analizy [A Vision of Poland’s Future—Studies and Analyses], vol. 1: Społeczeństwo i państwo [Society and State], vol. 2: Gospodarkai środowisko [Economy and Environment], and vol. 3: Ekspertyzy [ExpertStudies].

Background On December 2017 the Italian Parliament approved law n. 219/2017 “Provisions for informed consent and advance directives” regarding challenging legal and bioethical issues related to healthcare decisions and end-of-life choices. The law does not contain an explicit reference to Ethics Committees (ECs), but they could still play a role in implementing the law. Methods A questionnaire-based survey was performed among the ECs of the Italian Institute for Research and Care belonging to the Network of neuroscience and neurorehabilitation, with the (...) aim of (1) knowing whether the ECs participated and, if so, how in the process of implementation of law n. 219/2017 in the referring institutes; (2) investigating the point of view of the ECs regarding their possible involvement in the process; (3) exploring the contribution ECs can provide to give effective implementation to the law principles and provisions. Results Seventeen ECs out of thirty took part in the survey; the characteristics of the responding and non-responding committees are similar, so the responding ECs can be regarded as representative of all ECs in the Network. Nine ECs did not discuss the law in anyway: the main reason for this is that the referring institutions (6) and the health care professionals (3) did not ask for an EC intervention. Nevertheless, the large majority of the ECs believe that their involvement in the implementation of the law as a whole is appropriate (8) or absolutely appropriate (6), while 3 of them are neutral. No EC believes that the involvement is inappropriate. The aspect of the law on which the 14 ECs converge in considering the EC involvement appropriate/absolutely appropriate is the one related to the health facilities obligation to guarantee the full and proper implementation of the principles of the law. Conclusions Our survey confirms that ECs believe they can play a role in the implementation of law n. 219/2017, although this does not entirely correspond to what the committees have actually done in reality. This role could be better exercised by ECs specifically established for clinical practice, which would have a composition, functioning and a mandate better suited to the purpose. This supports the call for a national regulation of ECs for clinical practice. (shrink)

ICRC has coordinated relief for victims who are ignored by the world, in more places than all the UN agencies combined. When law is silent, as often during war time it is, human rights policies must be built on ethical choice.

Perhaps the strongest argument for scientific realism, the no-miracles-argument, has been said to commit the so-called base rate fallacy. The apparent elusiveness of the base rate of true theories has even been said to undermine the rationality of the entire realism debate. In this paper, I confront this challenge by arguing, on the basis of the Kuhnian picture of theory choice, that a theory is likely to be true if it possesses multiple theoretical virtues and is embraced by numerous (...) scientists, even when the base rate converges to zero.

When ethics committees evaluate the research proposals submitted to them by biomedical scientists, they can seek guidance from laws and regulations, their own beliefs, values and experiences, and from the theories of philosophers. The starting point of this paper is that philosophers can only be helpful to the members of ethics committees if they take into account in their models both the basic moral intuitions that most of us share and the consequences of people's choices. A moral view which can (...) be labelled as a consequentialist interpretation of mid-level principlism is developed, defended and applied to some real-life and hypothetical research proposals.

Social choice theory is the study of collective decision processes and procedures. It is not a single theory, but a cluster of models and results concerning the aggregation of individual inputs (e.g., votes, preferences, judgments, welfare) into collective outputs (e.g., collective decisions, preferences, judgments, welfare). Central questions are: How can a group of individuals choose a winning outcome (e.g., policy, electoral candidate) from a given set of options? What are the properties of different voting systems? When is a voting (...) system democratic? How can a collective (e.g., electorate, legislature, collegial court, expert panel, or committee) arrive at coherent collective preferences or judgments on some issues, on the basis of its members' individual preferences or judgments? How can we rank different social alternatives in an order of social welfare? Social choice theorists study these questions not just by looking at examples, but by developing general models and proving theorems. (shrink)

Simonet, Emanuel Nicolas Cortes; Herbert, Dilinie The Caroline Chisholm Centre for Health Ethics1 was established through the collaboration of private catholic hospitals in Victoria, namely: Cabrini Health, Calvary Health Care Bethlehem, Caritas Christi Hospice, Mercy Hospital for Women, Mercy Werribee Hospital, Mercy Palliative Care, St John of God Health Care, St Vincent's Hospital Melbourne, and St Vincent's Private Hospital Melbourne. Our role is to develop, review and respond to policies and procedures affecting Catholic Health Care; provide educational resources and formation (...) in ethics and offer ethics consultation and advisement. The Chisholm Health Ethics Bulletin is our quarterly publication that reports on ethical issues arising in health care as well as literature reviews of pertinent research topics that effect national and international interests.

One construal of convergent realism is that for each clear question, scientific inquiry eventually answers it. In this paper we adapt the techniques of formal learning theory to determine in a precise manner the circumstances under which this ideal is achievable. In particular, we define two criteria of convergence to the truth on the basis of evidence. The first, which we call EA convergence, demands that the theorist converge to the complete truth "all at once". The second, which (...) we call AE convergence, demands only that for every sentence in the theorist's language, there is a time at which the theorist settles the status of the sentence. The relative difficulties of these criteria are compared for effective and ineffective agents. We then examine in detail how the enrichment of an agent's hypothesis language makes the task of converging to the truth more difficult. In particular, we parametrize first-order languages by predicate and function symbol arity, presence or absence of identity, and quantifier prefix complexity. For nearly each choice of values of these parameters, we determine the senses in which effective and ineffective agents can converge to the complete truth on an arbitrary structure for the language. Finally, we sketch directions in which our learning theoretic setting can be generalized or made more realistic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics Committees in HospitalsPat Milmoe McCarrick (bio)(Literature about hospital ethics committees has grown enormously since Scope Note 3 first appeared. This update provides new information about resources and documents now available while continuing to include important earlier sources.)Hospital ethics committees increasingly have taken hold in the United States since 1983, when the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research encouraged their (...) creation in its report, Deciding to Forego Life-Sustaining Treatment (III, 1983, p. 5).The President's Commission report (pp. 160-64) suggested the following roles for ethics committees: 1) review of treatment decisions made on behalf of incompetent, terminally ill patients; 2) review of medical decisions having ethical implications with the option, in cases of disagreement, to refer cases to a court with proper jurisdiction; 3) provision of social, psychological, spiritual, or other counseling for patients, family members, physicians, or other hospital staff; 4) establishing guidelines regarding treatment or other medical decisions; and 5) sponsoring or conducting educational programs to inform all concerned, including the public, about ethical problems in medicine.No exact count of these committees is available. According to estimates cited by Donald F. Phillips, managing editor of Hospital Ethics, about two-thirds to three-fourths of hospitals with more than 200 beds have ethics committees, as do about one-third of hospitals under 200 beds. He thinks that about half of the 6,000 hospitals in the United States now have working ethics committees.Several journal articles and a court decision in the late 1970s influenced their formation. A 1975 journal article by pediatrician Karen Teel (VII A) urged the use of hospital ethics committees to provide for dialogue in individual care situations as an appropriate sharing of responsibility. Another early article suggested that beyond parents and treating physicians, a "disinterested," mixed lay and medical committee could consider cases about defective newborns to improve the ethical decisionmaking process (VII A, Robertson and Fost, 1976). Three 1977 discussions in the Hastings Center Report highlighted this new concept (VII A, Levine; Shannon; Veatch).Produced at the National Reference Center for Bioethics Literature, Kennedy Institute of Ethics, Georgetown University, Washington, DC 20057. It is supported by funds provided under grant number LM04492 from the National Library of Medicine, National Institutes of Health. Literature available through June 1992 is represented in this Scope Note. [End Page 285]The court decision was the March 31, 1976 ruling by the New Jersey Supreme Court in the Karen Quinlan case. The parents of a young woman in a persistent vegetative state had requested that she be taken off a respirator. The court designated a "prognosis" role for the hospital ethics committee and stipulated that the committee must concur that the patient will never return to a "cognitive, sapient state" before the life-support system can be withdrawn (In the Matter of Karen Quinlan, 70 N.J. 10, 355 A.2d 647, cert. denied sub nom. Garger v. New Jersey, 429 U.S. 922 (1976)). Shortly after the Quinlan decision, Massachusetts General Hospital's Clinical Care Committee created an ad hoc subcommittee (a psychiatrist, a legal counsel, an ICU nurse, an oncologist/internist, a surgeon, and a lay person who had recovered from serious cancer disease) which looked at 15 cases. Based on the subcommittee's success, establishment of a permanent committee to review treatment of the terminally ill was recommended by the critical care committee (VII A, Clinical Care Committee 1976).In its 1984 Baby Doe rules, the federal government recommended establishment of infant care review committees, which promoted the growth of hospital ethics committees (VII C, Povar 1991). In July 1987 Maryland became the first state to require by law that hospitals establish patient care advisory committees to offer advice about choices available in the care of life-threatening illnesses; this requirement was extended to nursing homes in 1990 [codified as amended at Md. Health-Gen. Code Ann. Sections 19-370 to -374 (1990)] (VII C, Hollinger 1991).Recently the role for these committees has been noted in the Accreditation Manual for Hospitals, 1992 Supplement (p. 10, Patient Rights, Section RI. 1.1.6.1) of the Joint Commission...

In this paper, it is about the axiomatic basis of rational choice theory - the theory that is behind making rational choice and decisions. To make rational choices, we would require thinking rationally and understanding the reason and logic behind what makes a choice rational, and how we need to choose rationally. Decisions are made under various circumstances, i.e., under risk, and often under compulsion. In social choice theory, decisions are made by different types of decision (...) making entities, i.e., committees, groups, individuals and collective judgments by various types of organizations, etc. This paper highlights these issues and addresses the fundamental tenets of making rational choices by examining and following the previous workings of experts on this field. As such, it introduces a novel concept and the idea of Social Choice Rationality in choosing what’s rational. (shrink)

In “The Choice Theory of Contracts,” we explain contractual freedom and celebrate the plurality of contract types. Here, we reply to critics by refining choice theory and showing how it fits and shapes what we term the “Contract Canon”. I. Freedom. (1) Charles Fried challenges our account of Kantian autonomy, but his views, we show, largely converge with choice theory. (2) Nathan Oman argues for a commerce-enhancing account of autonomy. We counter that he arbitrarily slights noncommercial spheres (...) central to human interaction. (3) Yitzhak Benbaji suggests that choice theory’s commitment to autonomy is overly perfectionist. Happily, in response to Benbaji, we can cite with approval Charles Fried’s point that contract types are “enabling our liberties.” II. Choice. (4) Aditi Bagchi criticizes our inattention to impediments to choice. We show how choice theory’s commitments to both multiplicity and relational justice ameliorate these impediments. (5) Gregory Klass explores parol evidence to highlight the mechanisms of choice. We substantially concur with his position, and show how such mechanisms can ensure voluntariness, an essential element of choice. (6) Oren Bar-Gill and Clayton Gillette question the institutional capacity of existing legal actors to implement choice theory. Working from the example of cohabitation, we offer a somewhat more optimistic view. III. Contracts. (7) Peter Benson contends our focus on the rational slights the reasonable. Although we did not use this Rawlsian vocabulary, choice theory complies with its strictures — more so than transfer theory. (8) Daniel Markovits and Alan Schwartz claim provocatively that contract theory must: capitulate before pluralism (as they endorse); leverage it; or fall victim to a so-called “embracing” approach (their charge against us). We reject the charge that choice theory is foundationally value-pluralist. Instead, we cabin pluralism and put it to work. (9) The Contract Canon starts on the next big step for choice theory by explaining existing doctrine (rebutting Benson on lack of fit) and helping adjudicate contract practice (countering Markovits and Schwartz on the vices of our pluralism). Each Article in this Issue advances the field; each prompts us to refine choice theory — all steps, we hope, toward a more just and justified law of contract. (shrink)

In lieu of an abstract, here is a brief excerpt of the content: Choice and Virtue in the Nicomachean Ethics ALFRED R. MELE COM~rNTATORS ON THr Nicomachean Ethics (NE) have long been laboring under the influence of a serious misunderstanding of one of the key terms in Aristotle's moral philosophy and theory of action. This term is prohairesis (choice), the importance of which is indicated by Aristotle's assertions that choice is the proximate efficient cause of action (NE (...) 6. 1139a31--32) and that in which "the essential elements of virtue and character" lie (NE 8. x163a2'~-23). The accepted view is that Aristotle employs two importantly different notions of choice in the NE, one on which the term refers exclusively to means or things which are pros (toward, related to)' ends and another on which it does not have this reference? This "two notion" interpretation is motivated by the following three considerations: i. Aristotle's good or virtuous agent is said (NE 2. 11o5a28-33, cf. NE 6. 1144ax8-2o ) to choose actions for their own sakes; but, according to the This paper is derived in part from a chapter of my doctoral dissertation, which was submitted to the University of Michigan in January of 1979. 1 would like to express my gratitttde to the chairman of my dissertation committee, Nicholas P. White, for his comments and criticisms on the relevant sections during the preparation of my dissertation and to theJHP's anonymous reviewers for their helpful criticisms and queries. ' It has often been pointed out that things which are pros an end are not necessarily "means," in the ordinary sense of the word. E.g., constituents of an end are pros the end, but they are not means to it. See, e.g., Nicomachean Ethics, Book 6, trans. Leonard H. G. Greenwood (Cambridge: Cambridge University Press, 19o9), pp. 46-47, 53ff.: and John M. Cooper, Reason and Human Good in Aristotle (Cambridge: Harvard University Press, 1975), pp. 1o-22. ' Among the many proponents of this "two notion" interpretation are William D. Ross and Donald J. Allan. See Ross, Aristotle, 5th ed. (London: Methuen, t953), p. 2oo. See Allan, The Philosophy of Aristotle, 2nd ed. (London: Oxford University Press, 197o), p. 132; idem, "Aristotle 's Account of the Origin of Moral Principles," Xlth International Congress of Philosophy 12 (1953):124; idem, "The Practical Syllogism," in Autour d'Aristote, Studies for A. Mansion (Louvain : Publications Universitaires, 1955). Richard Sorabji, in "Aristotle on the Role of Intellect in Virtue" (Proceedings of the Aristotelian Society 74 l t973-74]:t t6), says that he has noticed sixteen commentators who take this view. [4o5] 406 HISTORY OF PHILOSOPHY so-called formal account of prohairesis (NE 3. 2-3, 6. 2), the object of choice is what has been decided upon by deliberation (bouleuais), and what is decided upon by deliberation is a "means" to an end. 2. Aristotle says that choice is "closely bound up with virtue" and "discriminates characters better than actions do" (1 1t lb5; cf. t i lob3t, 1117a 5, 1163a22, 1t64bi); but commentators argue that these claims about choice are false unless choice is "of ends." 3. Though Aristotle holds that the impetuous akrat~s (incontinent agent) does not deliberate (e.g., t 152a 18-19), he says that the akrat~s' choice is good (1152ax5--17; cf. l l51a5-- 7, 29--32); and this appears to contradict his position in Book 3 that the object of choice is what is decided upon by deliberation, s In this paper I shall show that only one (philosophically significant) notion ofprohairesis is employed in the NE, namely, the notion developed in the "formal account" of deliberation and choice (3- 2-3, 6. 2), according to which choice is specifically of things which are pros ends. This point has several interesting applications. For example, it makes it easier to find in Aristotle (as I shall briefly explain) a comprehensive theory of practical reasoning or inference rather than several unconnected accounts of what practical inference is like in different types of cases; and it is helpful in clarifying what is involved in the evaluation of character on Aristotle's view (see Sec. ~). However, though I do think that the main point to be made... (shrink)

Temporal discounting is the tendency to devalue temporally distant rewards. Past studies have examined the k-value, the indifference point, and the area under the curve as dependent measures on this task. The current study included these three measures and a fourth measure, called the interest rate total score. The interest rate total score was based on scoring only those items in which the delayed choice should be preferred given the expected return based on simple interest rates. In addition, associations (...) with several individual difference measures were examined including intelligence, executive functions (inhibition, working memory, and set-shifting), thinking dispositions (Need for Cognition and Consideration of Future Consequences) and engagement in substance use and gambling behavior. A staircase temporal discounting task was examined in a sample of 99 university students. Replicating previous studies, temporal discounting increased with longer delays to reward and decreased with higher reward magnitudes. A hyperbolic function accounted for variance in temporal discounting better than an exponential function. Reaction time at the indifference point was significantly longer than at the other choice points. The four dependent measures of temporal discounting were all significantly correlated and were also significantly associated with our individual difference measures. That is, the tendency to wait for a larger delayed reward on all of the temporal discounting measures was associated with higher intelligence, higher executive functions and more consideration of future consequences. Associations between our measures of temporal discounting and outcomes related to substance use and gambling behavior were modest in our university sample. (shrink)

Recent studies of scientific interaction based on agent-based models suggest that a crucial factor conducive to efficient inquiry is what Zollman has dubbed ‘transient diversity’. It signifies a process in which a community engages in parallel exploration of rivaling theories lasting sufficiently long for the community to identify the best theory and to converge on it. But what exactly generates transient diversity? And is transient diversity a decisive factor when it comes to the efficiency of inquiry? In this paper we (...) examine the impact of different conditions on the efficiency of inquiry, as well as the relation between diversity and efficiency. This includes certain diversity-generating mechanisms previously proposed in the literature, as well as some factors that have so far been neglected. This study is obtained via an argumentation-based ABM. Our results suggest that cautious decision-making does not always have a significant impact on the efficiency of inquiry while different evaluations underlying theory-choice and different social networks do. Moreover, we find a correlation between diversity and a successful performance of agents only under specific conditions, which indicates that transient diversity is sometimes not the primary factor responsible for efficiency. Altogether, when comparing our results to those obtained by structurally different ABMs based on Zollman’s work, the impact of specific factors on efficiency of inquiry, as well as the role of transient diversity in achieving efficiency, appear to be highly dependent on the underlying model.

Committee decision making is examined in this study focusing on the role assigned to the committee members. In particular, we are concerned about the comparison between committee performance under specialization and non-specialization of the decision makers. Specialization (in the context of project or public policy selection) means that the decision of each committee member is based on a narrow area, which typically results in the acquirement and use of relatively high expertise in that area. When the (...) committee members’ expertise is already determined, specialization only means that the decision of each committee member is based solely on his/her relatively high expertise area. This form of specialization is potentially inferior relative to non-specialization under which the decision of each committee member is based on different areas, not just his/her relatively high expertise area. Given that the expertise of the committee members is already determined but unknown, our analysis focuses on non-specializing individuals whose decision is based on a decision rule that does not require information on the decision-making skills. Under these realistic assumptions, non-specialization is shown to be preferable over specialization, depending on the aggregation rule applied by the committee. The significance of our approach is not limited to the specific results that we obtain. Rather, it should be viewed as a first step toward a deeper examination of the role of individual decision makers in enhancing the performance of collective decision making. (shrink)

The purpose of this article is to provide a short overview of the condition of clinical ethics committees (CECs) and other forms of the so-called "ethics support" infrastructure. This includes but is not limited to CECs because some countries also have ethics consultation services that function independently from the CECs. It seems that properly structured CECs and other types of ethics support have a potential to act as facilitators of ethically sensitive healthcare decision-making. This goal can be achieved if the (...) ethics support infrastructure becomes an integral part of the healthcare institution where the majority of ethical dilemmas and the need for ethical debate arise. At the same time, CECs can become a useful tool for implementing bioethical standards developed at both national and international levels, including those established by the Council of Europe instruments. This is the main reason why the issue of developing clinical ethics support services might be very important for the Steering Committee on Bioethics (CDBI) of the Council of Europe. More specifically, the question is what special role ethics support services can play in the context of the follow up to the Council of Europe Symposium in the decision-making process regarding medical treatment in end-of-life situations (Strasbourg, 30 November-1 December). Very often, cases to be considered by the CECs and ethics consultants deal with the difficult end-of-life treatment choices. (shrink)

The aim of this article is to analyse the meaning and the implications of the comparative interpretation of Sartre’s and Ryle’s theses on imagination that Ricœur undertook in the still unpublished text of his Lectures on Imagination. These lectures were delivered at the University of Chicago in 1975. First, the article shows how Ricœur brings out a strong convergence , both in the method and in the presuppositions , of the Sartrean and Rylean conceptions of imagination : the (...) class='Hi'>choice of a descriptive method leads the two philosophers to a common critique of the mental image . Secondly, the article analyses the properly critical side of the Ricœurian interpretation by showing how it eventually brings to light the common theoretical limitation of Sartre’s and Ryle’s theses on imagination. According to Ricœur, those theses lead to a conception of image as picture and fail to consider the image as fiction , and so they remain locked in a theory of reproductive imagination and of the primacy of perception. Résumé Cet article se propose d’analyser le sens et les enjeux de la lecture croisée des thèses de Sartre et Ryle sur l’imagination à laquelle se livre Ricœur dans le texte encore inédit des Lectures on imagination professées en 1975 à l’Université de Chicago. Dans un premier temps, il montre comment Ricœur met en relief une convergence forte , de méthode et de présupposés entre les conceptions sartrienne et rylienne de l’imagination : le choix d’une méthode descriptive conduisant les deux philosophes à une commune critique de l’image mentale . Puis, dans un second temps, il analyse le versant proprement critique de la lecture ricœurienne en montrant comment elle en vient à dénoncer une commune limitation théorique des thèses de Sartre et Ryle sur l’imagination.

In this book Joseph Heath brings Jürgen Habermas's theory of communicative action into dialogue with the most sophisticated articulation of the instrumental conception of practical rationality-modern rational choice theory. Heath begins with an overview of Habermas's action theory and his critique of decision and game theory. He then offers an alternative to Habermas's use of speech act theory to explain social order and outlines a multidimensional theory of rational action that includes norm-governed action as a specific type.In the second (...) part of the book Heath discusses the more philosophical dimension of Habermas's conception of practical rationality. He criticizes Habermas's attempt to introduce a universalization principle governing moral discourse, as well as his criteria for distinguishing between moral and ethical problems. Heath offers an alternative account of the level of convergence exhibited by moral argumentation, drawing on game-theoretic models to specify the burden of proof that the theory of communicative action and discourse must assume.

Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross-modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a two-alternative (...) forced choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl-aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross-modal matching reaction time, specifically in the hard word condition. These Cho... (shrink)

In decision-making based on multiple criteria, situations may arise where agents find their options to be neither better than, worse than nor equal to each other with respect to the relevant criteria. How, if at all, can a justified choice be made between such options? Are the options incomparable? This article explores a hypothetical case that illustrates how such a situation can arise in an environmental context; more specifically, it considers the deliberations of an imagined 'ethics committee' as (...) it struggles to decide whether or not a deep-sea mining project should be allowed to proceed. I argue that the case is best understood as involving options that are comparable in the sense of being 'on a par'. Working out from a discussion of Ruth Chang's 'self-governance' theory of choice in cases of parity, I suggest that, in the environmental context, the idea of choices expressing a moral identity may lead us in the direction of a plausible solution to these particularly challenging cases.

The author considers the religious paradigm of the culture of coexistence in the value measure of moral activity, which establishes in personality and social being the individuality of each, choice and responsibility; the idea of freedom and positive change, convergence of opposing systems through the gradual overcoming of conflicts and contradictions that arise on the political, economic, religious and ethnic grounds; involves cultural interaction, dialogue and trust.

Research ethics committees (RECs) have played a crucial role in expediting the review of research protocols amidst the COVID‐19 pandemic. To improve their performance and identify areas of enhancement, a multicentric study was conducted in India by the Forum for Ethical Review Committees in the Asian and Western Pacific Region (FERCAP). The study aimed to evaluate the preparedness of Indian RECs during the COVID‐19 outbreak while conducting protocol reviews and comprehend the challenges they encountered. After obtaining ethics committee approval, (...) a cross‐sectional observational study was conducted using two validated questionnaires, one for REC member secretaries/chairpersons and another for REC members. The questionnaires consisted of 13 multiple‐choice questions, 10 yes or no questions, and 2 open‐ended questions each. The study was distributed to multiple RECs. A total of 109/200 participants, including 13 REC member secretaries, 12 chairpersons and 84 REC members from a total of 34 REC's, consented to participate in the study. During the COVID‐19 pandemic, 23/25 (92%) of the RECs conducted online meetings. The most common challenges faced by RECs included risk‐benefit analysis (12/25 RECs), review of informed consent (12/25 RECs), and protocols involving vulnerable populations (10/25 RECs). 65% of the REC members reported the need for ethics review training, and 66/84 REC members agreed or strongly agreed that RECs require training in COVID‐19 protocol review. Additionally, 62/84 REC members agreed or strongly agreed that central/joint RECs should review multicenter COVID‐19 protocols. RECs in India encountered difficulties while reviewing risk‐benefit analyses, informed consent documents (ICDs), and COVID‐19 protocols and they suggested providing training on these topics.

ABSTRACT The question concerning the connection of scientific inquiry to democratic praxis is central to both Antonio Gramsci and John Dewey. They share a common philosophical origin in Hegel and are essentially both in the tradition of Left Hegelian thought. Likewise, their respective analyses of the forces obstructing democratic emancipation were sharply focused on the distortions of social life caused by economic agents cooperating under hugely unequal power relations. As Gramsci wrote from his prison cell from 1929 to 1937 in (...) Italy, Dewey went through his most fruitful philosophical period in the United States, including his writings on politics and democracy. They both found targets of critique by diagnosing the pathologies of public life resulting from the power of private capital interests in collusion with a co-opted representative body, the authoritarian crimes and attendant culture of fascism, and the theoretical rigidity of the Soviet Marxists. In addition, true to their Hegelian roots, they marshaled their critiques of the abstractions of liberalism and its attendant moral and economic theory by insisting on the embedded, cultural, and historically deep contexts in which emancipatory practice need take place.

There is something about the debate over reproductive technologies of all kinds—from coerced use of Norplant to trait-selection technologies, to issues surrounding in vitro fertilization, to fetal tissue transplantation—that seems to invite dubious analogies. A Tennessee trial court termed Mary Sue and Junior Davis's frozen embryos “in vitro children” and applied a best-interests standard in awarding “custody” to Mary Sue Davis; the Warnock Committee drew an implicit analogy between human gametes and transplantable organs in its recommendation of a voluntary, (...) nonprofit system for collecting and distributing gametes in the United Kingdom; Owen Jones compares the right to trait-selection to the right to abortion; Robert Veatch once claimed that if a woman had signed an organ donation card and then died while pregnant, she had in effect given consent to the attempt to sustain the pregnancy after her death; John Robertson has argued that contract pregnancy poses no problems we have not already encountered with adoption; and Andrea Bonnicksen has compared the wonders of preembryonic genetic screening to the riches housed in the gold museum in Bogota, Colombia.

In this paper, close attention is paid to the argumentative patterns resulting from combining pragmatic argumentation in which a recommendation is made with arguments in which the majority is invoked. I focus on such argumentative patterns as employed by European parliamentary committees of inquiry conducting inquiries into the activity of the Equitable Life Assurance Society. By incorporating legal and political insights about the activity of these parliamentary committees of inquiry into a pragma-dialectical argumentative approach, an analysis will be given of (...) the selected argumentative pattern. This analysis will reveal which standpoints are supported by which arguments and how these arguments relate to each other to increase the acceptability of the recommendation made. In addition, the analysis will explain the arguer’s argumentative choices in the pattern employed. (shrink)

Multidisciplinary healthcare committees meet regularly to discuss patients’ candidacy for emerging functional neurosurgical procedures, such as Deep Brain Stimulation . Through debate and discussion around the surgical candidacy of particular patients, functional neurosurgery programs begin to mold practice and policy supported both by scientific evidence and clear value choices. These neurosurgical decisions have special considerations not found in non-neurologic committees. The professional time used to resolve these conflicts provides opportunities for the emergence of careful, ethical practices simultaneous with the expansion (...) of therapy applications. (shrink)

The current note clarifies why, in committees, the prior probability of a correct collective choice might be of particular significance and possibly should sometimes even be the sole appropriate basis for making the collective decision. In particular, we present sufficient conditions for the superiority of a rule based solely on the prior relative to the simple majority rule, even when the decisional skills of the committee members are assumed to be homogeneous.

A collection celebrating some of the best essays from the Blackwell journals, Bioethics and Developing World Bioethics. Contributors include Helga Kuhse, Michael Selgelid and Baroness Mary Warnock, former Chair of the British Government’s Committee of Inquiry into Human Fertilization and Embryology’s. Traces some of the most important concerns of the 1980s, such as the ethics of euthanasia, reproductive technologies, the allocation of scarce medical resources, surrogate motherhood, through to a range of new issues debated today, particularly in the field (...) of genetics. Includes contributions that are still as hotly debated today as they were 20 years ago and serves as a salutary reminder that free and open discussion is vital to the health of the discipline itself. Includes eight sections comprising some of the journals' best publications in methodological issues, the health care professional-patient relationship, public health ethics, research ethics, genetics, as well as beginning- and end-of-life issues. Will serve the academic bioethicists as well as students of bioethics as an excellent source book. (shrink)

This book is a theoretical and completely rigorous analysis of voting in committees that provides mathematical proof of the existence of democratic voting systems, which are immune to the manipulation of preferences of coalitions of voters. The author begins by determining the power distribution among voters that is induced by a voting rule, giving particular consideration to choice by plurality voting and Borda's rule. He then constructs, for all possible committees, well-behaved representative voting procedures which are not distorted by (...) strategic voting, giving complete solutions for certain important classes of committees. The solution to the problem of mass elections is fully characterised. (shrink)

Modal logic provides an elegant way to understand the notion of potential infinity. This raises the question of what the right modal logic is for reasoning about potential infinity. In this article I identify a choice point in determining the right modal logic: Can a potentially infinite collection ever be expanded in two mutually incompatible ways? If not, then the possible expansions are convergent; if so, then the possible expansions are branching. When possible expansions are convergent, the right modal (...) logic is S4.2, and a mirroring theorem due to Linnebo allows for a natural potentialist interpretation of mathematical discourse. When the possible expansions are branching, the right modal logic is S4. However, the usual box and diamond do not suffice to express everything the potentialist wants to express. I argue that the potentialist also needs an operator expressing that something will eventually happen in every possible expansion. I prove that the result of adding this operator to S4 makes the set of validities Pi-1-1 hard. This result makes it unlikely that there is any natural translation of ordinary mathematical discourse into the potentialist framework in the context of branching possibilities. (shrink)

Whether the food movement is most likely to transform the food system through ‘alternative’ or ‘oppositional’ initiatives has been the focus of considerable scholarly debate. Alternative initiatives are widespread but risk reinforcing the conventional food system by supporting neoliberal discourse and governance mechanisms, including localism, consumer choice, entrepreneurialism and self-help. While oppositional initiatives such as political advocacy have the potential for system-wide change, the current neoliberal political and ideological context dominant in Canada poses difficulties for initiatives that explicitly oppose (...) the conventional food system. As such, some argue that the food movement requires convergence between alternative and oppositional initiatives. In this paper, we investigate convergence using survey results from 143 food movement organizations in four Canadian provinces. Results based on cluster analysis and descriptive statistics on organizational discourse, activities and visions of sustainable food systems demonstrate convergence around neoliberal discourse and governance mechanisms. Localism and consumer education characteristics are particularly prominent, with a majority of respondents describing their organizations as ‘local’, engaging in consumer education activities, and stating the importance of consumer education activities, indicating convergence around alternative, rather than oppositional, initiatives. While convergence around these discourse and strategies may limit the transformative potential of the food system when interpreted as neoliberalisation of the movement, such a reading does not demonstrate their full potential, as survey results also indicate trends of transformative visions of change and political engagement, particularly at the municipal level. This research demonstrates that the movement can work simultaneously within, and opposed to, the conventional food system, and provides understanding of both neoliberal leanings and the politics of the possible of the food movement.

A central concern of Joseph Heath's Communicative Action and Rational Choice is to find a plausible response to “the problem of convergence … to explain why we should ever expect to secure agreement on moral questions”. In Chapter 7 of his book, Heath proposes what he calls “a pragmatic theory of convergence.” This account is presented as contrasting with the one proposed by Jürgen Habermas, which emphasizes the existence of an internal relation between convergence and moral (...) truth. According to Habermas, there is a “connection … between moral cognitivism and the expectation of convergence”. One cannot take moral judgements to be amenable to rational justification unless one also assumes that an agreement among those participating in the discursive evaluation of that moral judgement is possible in principle. Heath considers this claim about a supposed internal connection as a remnant of foundationalism in Habermas's otherwise promissory contextualist account of moral justification. To reject non-cognitivism, according to Heath, we need not demonstrate that convergence on moral judgement is always forthcoming. It is enough to show that ordinary moral thinking takes moral claims as amenable to discursive justification. As to whether actual practices of discursive justification of moral claims will indeed end in agreement or convergence, a “wait and see” attitude seems all we can legitimately hope for. (shrink)

With each novel infectious disease outbreak, there is scholarly attention to healthcare providers’ obligation to assume personal risk while they care for infected patients. While most agree that healthcare providers have a duty to assume some degree of risk, the extent of this obligation remains uncertain. Furthermore, these analyses rarely examine healthcare institutions’ obligations during these outbreaks. As a result, there is little practical guidance for healthcare institutions that are forced to weigh whether or when to exclude healthcare providers from (...) providing care or allow them to opt out from providing care to protect themselves. This article uses the COVID-19 pandemic to examine the concept of risk and the professional duties of both healthcare providers and healthcare institutions, and proposes a framework that can be used to make concrete institutional policy choices. This framework should be a useful tool for any hospital, clinic, or health agency that must make these choices during the current pandemic and beyond. (shrink)

One of the central issues in comparative law and political economy is whether the forces of globalization will result in the convergence of public policies across countries. Noting in particular that taxes collected still cover a considerable range across industrialized countries — from a low of 20% of GDP to a high of 50% — some have argued that globalization has not resulted in a loss of tax sovereignty. However, following a review of the evidence, in this Article we (...) conclude that globalization has had significant but subtle effects on tax levels and structures. Moreover, these pressures will make it increasingly difficult for countries to raise revenue to finance new public needs and to structure their tax systems in order to achieve a more socially acceptable distribution of income than what market forces dictate. Tax levels in most countries have remained essentially flat over the past twenty years, but there is a host of reasons for thinking they would have continued to rise were it not for the pressures of globalization. Statutory corporate tax rates have declined dramatically and, although corporate tax revenues have remained robust, this has been due to factors unrelated to deliberate tax policy choices. Personal marginal tax rates have also declined sharply and tax revenues have been increasingly raised by regressive consumption taxes. These trends stem from tax competition brought on by the forces of globalization, not from changing ideas or other political variables. In this Article we conclude that in order to prevent tax competition from completely eroding the ability of countries to fashion their own tax systems, there will have to be considerable cooperation among the major countries and some harmonization of aspects of their tax systems, particularly as they apply to footloose factors of production.

For over 100 years, the field of contemporary public health has existed to improve the health of communities and populations. As public health practitioners conduct their work – be it focused on preventing transmission of infectious diseases, or prevention of injury, or prevention of and cures for chronic conditions – ethical dimensions arise. Borrowing heavily from the ethical tools developed for research ethics and bioethics, the nascent field of public health ethics soon began to feel the limits of the clinical (...) model and began creating different frameworks to guide its ethical challenges. Several public health ethics frameworks have been introduced since the late 1990s, ranging from extensions of principle-based models to human rights and social justice perspectives to those based on political philosophy. None has coalesced as the framework of choice in the discipline of public health. This paper examines several of the most-known frameworks of public health ethics for their common theoretical underpinnings and values, and suggests next steps toward the formulation of a single framework.

An important function in all scholarly and academic activities is the participation in the peer review system. One aspect of this peer review evaluation is service on committees judging candidates for important awards, prizes and fellowships. Some reflective observations on this process are made in which a number of factors determining the final choice are identified. It is pointed out that the decisions of such committees are based not only on relevant and objective criteria but are also influenced by (...) a number of irrelevant criteria; caution must be exercised to minimize the effect of the latter factors in order to maintain the highest ethical standards in the selection process. The ranking practices of awards committees, national academies and learned societies are briefly reviewed by pointing out some ethical pitfalls, anecdotal incidents, and the ways to avoid the tarnishing of the selection process.
