Recent research on human problem solving has largely focused on laboratory tasks that do not demand from the subject much prior, task‐related information. This study seeks to extend the theory of human problem solving to semantically richer domains that are characteristic of professional problem solving. We discuss the behavior of a single subject solving problems in chemical engineering thermodynamics. We use as a protocol‐encoding device a computer program called SAPA which also doubles as a theory of the subject's problem‐solving behavior. (...) The subject made extensive use of means‐ends analysis, similar to that observed in semantically less rich domains, supplemented by recognition mechanisms for accessing information in semantic memory.

The ethics of conducting research in epidemic situations have yet to account fully for differences in the proportion and acuteness of epidemics, among other factors. While epidemics most often arise from infectious diseases, not all infectious diseases are of epidemic proportions, and not all epidemics occur acutely. These and other variations constrain the generalization of ethical decision-making and impose ethical demands on the individual researcher in a way not previously highlighted. This paper discusses a number of such constraints and impositions. (...) It applies the ethical principles enunciated by Emmanuel et al.1 to the controversial Pfizer study in Nigeria in order to highlight the particular ethical concerns of acute epidemic research, and suggest ways of meeting such challenges. The paper recommends that research during epidemics should be partly evaluated on its own merits in order to determine its ethical appropriateness to the specific situation. Snap decisions to conduct research during acute epidemics should be resisted. Community engagement, public notification and good information management are needed to promote the ethics of conducting research during acute epidemics. Individual consent is most at risk of being compromised, and every effort should be made to ensure that it is maintained and valid. Use of data safety management boards should be routine. Acute epidemics also present opportunities to enhance the social value of research and maximize its benefits to communities. Ethical research is possible in acute epidemics, if the potential challenges are thought of ahead of time and appropriate precautions taken. (shrink)

Weakly acyclic games form a natural generalization of the class of games that have the finite improvement property. In such games one stipulates that from any initial joint strategy some finite improvement path exists. We classify weakly acyclic games using the concept of a scheduler introduced in Simon and Apt. We also show that finite games that can be solved by the iterated elimination of never best response strategies are weakly acyclic. Finally, we explain how the schedulers allow us (...) to improve the bounds on finding a Nash equilibrium in a weakly acyclic game. (shrink)

When we reason about strategic games, implicitly we need to reason about arbitrary strategy profiles and how players can improve from each profile. This structure is exponential in the number of players. Hence it is natural to look for subclasses of succinct games for which we can reason directly by interpreting formulas on the (succinct) game description rather than on the associated improvement structure. Priority separable games are one of such subclasses: payoffs are specified for pairwise interactions, and from these, (...) payoffs are computed for strategy profiles. We show that equilibria in such games can be described in Monadic Least Fixed Point Logic (MLFP). We then extend the description to games over arbitrarily many players, but using the monadic least fixed point extension of existential second order logic. (shrink)

Background: The regulation of muscle force is a vital aspect of sensorimotor control, requiring intricate neural processes. While neural activity associated with upper extremity force control has been documented, extrapolation to lower extremity force control is limited. Knowledge of how the brain regulates force control for knee extension and flexion may provide insights as to how pathology or intervention impacts central control of movement.Objectives: To develop and implement a neuroimaging-compatible force control paradigm for knee extension and flexion.Methods: A magnetic resonance (...) imaging safe load cell was used in a customized apparatus to quantify force during neuroimaging. Visual biofeedback and a target sinusoidal wave that fluctuated between 0 and 5 N was provided via an MRI-safe virtual reality display. Fifteen right leg dominant female participants completed a knee extension and flexion force matching paradigm during neuroimaging. The force-matching error was calculated based on the difference between the visual target and actual performance. Brain activation patterns were calculated and associated with force-matching error and the difference between quadriceps and hamstring force-matching tasks were evaluated with a mixed-effects model.Results: Knee extension and flexion force-matching tasks increased BOLD signal among cerebellar, sensorimotor, and visual-processing regions. Increased knee extension force-matching error was associated with greater right frontal cortex and left parietal cortex activity and reduced left lingual gyrus activity. Increased knee flexion force-matching error was associated with reduced left frontal and right parietal region activity. Knee flexion force control increased bilateral premotor, secondary somatosensory, and right anterior temporal activity relative to knee extension. The force-matching error was not statistically different between tasks.Conclusion: Lower extremity force control results in unique activation strategies depending on if engaging knee extension or flexion, with knee flexion requiring increased neural activity for the same level of force and no difference in relative error. These fMRI compatible force control paradigms allow precise behavioral quantification of motor performance concurrent with brain activity for lower extremity sensorimotor function and may serve as a method for future research to investigate how pathologies affect lower extremity neuromuscular function.

Concerns have been expressed about adult behaviour at children’s sporting events in New Zealand. As a consequence, covert observation was identified as the optimal research method to be used in studies designed to record the nature and prevalence of adult sideline behaviour at children’s team sporting events. This paper explores whether the concerns raised by the ethics committee about the use of this controversial method, particularly in relation to the lack of informed consent, the use of deception, and researcher safety, (...) were effectively managed. This is achieved by reflecting on the conduct and findings of the research and by drawing on the perspectives of research assistants who carried out the covert observation. The authors argue that in the context of these studies, the ends have justified the means and with careful attention to the design of the study the complex ethical tensions arising from the use of this method can be managed.

The vacuum is fast emerging as the central structure of modern physics. This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification program. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity. This book is a work in modern metaphysics, in which the concepts (...) of substance and space interweave in the most intangible of forms, the background and context of our physical experience: vacuum, void, or nothingness.

Causal queries about singular cases, which inquire whether specific events were causally connected, are prevalent in daily life and important in professional disciplines such as the law, medicine, or engineering. Because causal links cannot be directly observed, singular causation judgments require an assessment of whether a co‐occurrence of two events c and e was causal or simply coincidental. How can this decision be made? Building on previous work by Cheng and Novick (2005) and Stephan and Waldmann (2018), we propose a (...) computational model that combines information about the causal strengths of the potential causes with information about their temporal relations to derive answers to singular causation queries. The relative causal strengths of the potential cause factors are relevant because weak causes are more likely to fail to generate effects than strong causes. But even a strong cause factor does not necessarily need to be causal in a singular case because it could have been preempted by an alternative cause. We here show how information about causal strength and about two different temporal parameters, the potential causes' onset times and their causal latencies, can be formalized and integrated into a computational account of singular causation. Four experiments are presented in which we tested the validity of the model. The results showed that people integrate the different types of information as predicted by the new model. (shrink)

Liberal neutrality requires that, given the diversity of conceptions of the good life held by people, the state should be in some sense neutral between these conceptions. Just what that sense is has been a matter of debate but it seems generally accepted that neutrality is a property of the justifications for government action and not of the consequences of such action. In other words, the state must be neutral by avoiding invoking any conception of the good in its justification (...) for laws and policies and by avoiding having any laws and policies that can be justified only by reference to some conception of the good. It need not, so it seems generally accepted, ensure that the consequences of its laws and policies do not favor some conceptions of the good over others. Against this commonly held view, in this chapter I argue that justificatory neutrality is inadequate as a full picture of what liberal neutrality means and that some conception of consequential neutrality is more plausible.

Like no other philosopher of this century, the late Yves R. Simon grappled with philosophical issues that still carry weight today. This collection of his essays explores an impressive range of genuinely foundational topics of philosophical inquiry. These essays discuss, among other topics, the relationship between faith and reason, the nature of sensation, and the various meanings of work. SimonOs significant contribution to philosophy through these varied essays is unquestionable, and this is the first such collection of his works. (...) Philosopher at Work will be indispensable for philosophers of all backgrounds. (shrink)

Addressing both collegiate and professional sports, the updated edition of Fair Play: The Ethics of Sport explores the ethical presuppositions of competitive athletics and their connection both to ethical theory and to concrete moral dilemmas that arise in actual athletic competition. This fourth edition has been updated with new examples, including a discussion of Spygate by the New England Patriots and recent discoveries on the use of performance enhancing drugs by top athletes. Two additional authors, Cesar R. Torres and Peter (...) F. Hager, bring to this edition a discussion of the moral issues involved in youth sports and the ethics of being a fan, as well as a fresh perspective on the theories of broad internalism and the quest for excellence. Furthermore, major criticisms of broad internalism by philosophers William J. Morgan and Scott Kretchmar add a new dimension to the discussion on the moral foundations of winning. (shrink)

This paper aims to integrate insights from psychoanalytic theory into business ethics research on the sources of ethical failures within organizations. We particularly draw from the analysis of sources and outcomes of neurotic processes that are part of human development, as described by the psychoanalyst Karen Horney and more recently by Manfred Kets de Vries; we interpret their insights from a stakeholder theory perspective. Business ethics research seems to have overlooked how “neurotic management styles” could be the antecedents of unethical (...) behavior within organizations. After showing the connection between five managerial neuroses and the corresponding potential ethical failures within organizations that have been already identified within business ethics research, we suggest three organizational strategies to counteract these failures. First, we argue that managers should pay greater attention at the complexity of human motivation, avoiding the simplistic view of compliance‐based approaches. Second, we discuss the importance of developing a conversation around values within organizations, enabling healthy individual growth and limiting the emergence of neurotic processes. Finally, we discuss the role of the business ethicist in facilitating such a process, suggesting a parallel between the role of the business ethicist and that of the psychoanalytic therapist.

This edited volume of original contributions deals with the economic and political thought of Michael Polanyi. Requiring little prior knowledge of Polanyi, this volume further develops a somewhat neglected side of Polanyi's work. In particular it examines the 'tacit integration', of subsidiary details into focal objects or actions as central to all knowing and action. It traces ontological counterparts in the structures of comprehensive entities and complex actions, and a multi-level universe in which lower levels have their boundary conditions, the (...) extents to which they apply, determined by those of the next higher level, whilst each possessing its own laws or operative principles. This schema of 'dual control' preserves the reality and relative autonomy of each level, and its interactions with others, against the various reductions. The essays in this volume also employ and develop important additional concepts and distinctions such as: 'corporate' and 'spontaneous' order; 'public' and 'private' liberties; 'general' and 'specific authority'; and 'moral inversion'; which, as the essays show, are necessary for understanding and maintaining a free society and the freedom of institutions within it. Among the topics treated with them are: more of the prerequisites of freedom in public liberties dedicated to principles and transcendent values; totalitarianism and society as spontaneous order; the balance of general and specific authority in society and particular institutions; reductionism, totalitarianism and consumption in consumer societies, as moral inversions; the mutual interactions of economics and politics as distinct and autonomous but interacting levels; the sociological aspects of economics; and Polanyi's own contributions to sociology. Although, as indicated, Polanyi has his special terms, the essays in this volume, like his works, give them meaning with concrete examples and so avoid merely shuffling a mass of abstractions. Together the essays show that his work is a rich seam of ideas and inspiration for yet further extension and application--Publisher. (shrink)

First published in 1962, this classic study examines the relationship between authority and justice, life, truth, and order. Simon, himself a passionate proponent of liberty, defends authority as an essential concomitant of liberty.

In Beyond Neutrality, George Sher criticises the idea that state neutrality between competing conceptions of the good helps protect society from oppression. While he is correct that some governments are non-neutral without being oppressive, I argue that those governments may be neutral at the core of their foundations. The possibility of non-neutrality leading to oppression is further explored; some conceptions of the good would favour oppression while others would not. While it is possible that a non-neutral state may avoid oppression, (...) it is argued that the risks are so great that it is better to bet on government being neutral, thereby minimizing the possibility of oppression.

The authors challenge the reigning “causal power framework” as an explanation for whether a particular outcome was actually caused by a specific potential cause. They test a new measure of causal attribution in two experiments by embedding the measure within the Structure Induction model of Singular Causation (SISC, Stephan & Waldmann, 2016).

In the reported, experiment participants hit a ball to aim at the vertex of a Müller–Lyer configuration. This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution. A significant illusion bias was observed in all perturbation conditions, but not in the stationary condition. The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments . These (...) findings indicate that allocentric information is exploited for online control when people make rapid adjustments in response to a sudden change in the environment and not when people guide their limb movements to interact with a stable environment.

A major argument for vegetarianism is that eating animals causes unjustified suffering. While this argument has been articulated by several people, it has received surprisingly little attention. Here I restate it in a way that I believe is most convincing, considering and rejecting the two main justifications for causing suffering in order to eat animals. I compare it to some other prominent arguments for vegetarianism, and discuss a major objection to the argument which focuses on whether the animals would not (...) exist if not bred to be eaten.

Passivity experiences in schizophrenia are thought to be due to a failure in a neurocognitive action self-monitoring system . Drawing on the assumption that inner speech is a form of action, a recent model of auditory verbal hallucinations has proposed that AVHs can be explained by a failure in the NASS. In this article, we offer an alternative application of the NASS to AVHs, with separate mechanisms creating the emotion of self-as-agent and other-as-agent. We defend the assumption that inner speech (...) can be considered as a form of action, and show how a number of previous criticisms of applying the NASS to AVHs can be refuted. This is achieved in part through taking a Vygotskian developmental perspective on inner speech. It is suggested that more research into the nature and development of inner speech is needed to further our understanding of AVHs. (shrink)

This essay addresses the role of trust in political philosophy. In particular, it examines the idea that trust is necessary for a particular type of government action — paternalistic action — to be justified. Liberal theory and liberal democratic practice are characterized by a large degree of anti-paternalism, understanding paternalism to be the restriction of individual liberty for a person’s good, instead of to protect or benefit others. It would be a mistake to think that liberal democracies have no paternalism; (...) seatbelt, motorcycle helmet, and drug prohibition laws, for example, are probably at least partly motivated by paternalistic reasons. But it is easy to imagine more pervasive paternalism. Society could, and does in some cultures, restrict people’s choices of occupation, marriage partners, and where to live, with the rationale that these restrictions are for people’s good. Many people believe that the liberal position is the correct one, that more pervasive paternalism would be unjustified, but what is the philosophical justification for anti-paternalism? (shrink)

Brains are information processing systems whose operational principles ultimately cannot be understood without resource to information theory. We suggest that understanding how external signals are represented in the brain is a necessary step towards employing further engineering tools to understand the information processing performed by brain circuits during behaviour.

The phenomenology of auditory verbal hallucinations occurring in hypnagogic and hypnopompic states has received little attention. In a sample of healthy participants, 108 participants reported H&H AVHs and answered subsequent questions on their phenomenology. AVHs in the H&H state were found to be more likely to only feature the occasional clear word than to be clear, to be more likely to be one-off voices than to be recurrent voices, to be more likely to be voices of people known to the (...) individual than unknown persons, to be more likely to talk directly to the person rather than not, and to only rarely give commands, ask questions, or to result in an interactive conversation. Their phenomenology was similar to normative AVHs in wakefulness in that the voice-hearer was usually the target of the voice, and the voice was more likely to be of a recognized person. However, H&H AVHs differed from AVHs in wakefulness in that commands and questions were rare, and there was typically no dialogical engagement with the voice. We conclude by proposing that two distinct types of H&H AVHs may exist, based on an analysis of the phenomenology of the experience, and suggest avenues for future research. (shrink)

What makes individual freedom valuable? People have always believed in freedom, have sought it, and have sometimes fought and died for it. The belief that it is something to be valued is widespread. But does this belief have a rational foundation? This book examines answers to these questions that are based on the welfare of the person whose freedom is at stake. There are various conceptions of a worthwhile life, a life that is valuable for the person whose life it (...) is. These conceptions will be examined to see whether they are plausible and what their connection, if any, is to freedom. Are they compelling foundations for freedom? Does freedom make a person’s life better or would his/her welfare be advanced by restricting freedom? (shrink)

When, if ever, is paternalism justified? I defend the principle that paternalism is justified only if it is neutral, that is, the motivation for it is compatible with all conceptions of the good life. Three other principles of paternalism are examined. The balancing view says that we must balance the values of liberty and well-being against each other and that paternalism is justified only if well-being outweighs liberty. The consent principle says that paternalism is justified only if consented to. The (...) voluntariness principle says that intervention is justified only when the conduct in question is substantially nonvoluntary. These three views are either implausible, plausible only if they are supplemented with the neutrality principle, or plausible only because they already presuppose that principle. (shrink)

This paper defends Kant against a neo‐Hegelian line of criticism, recently advanced by John McDowell, Robert Pippin, and Sebastian Rödl, targeting Kant's alleged claim that forms of sensibility other than space and time are possible. If correct, the criticism identifies a deep problem in Kant's position and points toward Hegel's position and method as its natural solution. I show that Kant has the philosophical resources to respond effectively to the criticism, notably including the set of claims about the limits of (...) meaningful thought that P. F. Strawson calls Kant's “principle of significance.” By Kant's lights, first, the concept “non‐spatio‐temporal form of sensibility” is meaningless, so he cannot meaningfully grant that such a form is possible; and second, there is no need to prove (e.g., from reflection on pure intellect) that non‐spatio‐temporal forms of sensibility are impossible, because insofar as the concept “knowing” means anything, that meaning is provided by our own always‐already‐spatio‐temporal case. An upshot of the argument is that Kant's two “stems” of knowledge or cognition, sensibility and understanding, are merely aspects of a single epistemic capacity rather than each a separate capacity in its own right. Many today are unwilling to take Kant's claims about the limits of meaningful thought at face value, notwithstanding their ubiquity and explicitness. This paper is therefore an indirect argument on behalf of that dimension of Kant's position: We have something significant to lose in not taking it seriously. (shrink)

Moving across and beyond critical and industrial categories that inform thinking about cinema, it contends that different (...) approaches to film style can push us to imagine disaster in distinct ways, with distinct ethical connotations.

SummaryFrom 1996 to 2006, Nepal experienced a substantial fertility decline, with the total fertility rate dropping from 4.6 to 3.1 births per woman. This study examines the associations between progress towards universal primary and secondary schooling and fertility decline in rural Nepal. Several hypotheses regarding mechanisms through which education affects current fertility behaviour are tested, including: the school environment during women's childhood; current availability of schools; knowledge of educational costs; and women's own educational attainment. Data for the analysis come from (...) the 2003–04 Nepal Living Standards Survey, a nationally representative random sample of households, which includes detailed data on fertility, household expenditure, educational attainment, demographic characteristics and the use of social services. Census and administrative data are also used to construct district-level gross enrolment ratios for primary and secondary schools during the women's childhood. Discrete dependent variable modelling techniques are used to estimate the effects of the following variables on the probability of women giving birth in a given year: district-level gross enrolment ratios for primary and secondary schools during women's childhood; having had a child previously in school; women's own educational level; current school availability; and other covariates. Separate models are estimated for the overall sample of rural women of reproductive age, and for parity-specific sub-samples. The results suggest that district-level gross enrolment ratios for secondary schools and, in some instances, having had a previous child enrolled in school are significant determinants of fertility in rural areas. These results are highly independent of women's own educational levels. Overall, the results suggest that, in the rural Nepal context, mass schooling influences the fertility transition through both community- and household-level pathways. (shrink)

Disgust seems to play an important role in moral judgment. However, it is unclear whether the role of disgust in moral judgment is limited to certain kinds of moral domains (versus many) and/or certain types of disgust (versus many). To clarify these questions, we conducted a multilevel meta-analysis (k = 512; N = 72,443) on relations between trait disgust sensitivity and moral judgment (disgust-immorality association). Main analyses revealed a significant overall mean disgust-immorality association (r =.23). Additionally, moderator analyses revealed significant (...) specificity in disgust type and moral domain (grounded in Moral Foundations Theory): effects were stronger for (a) sexual disgust compared to pathogen disgust, (b) sanctity moral judgments compared to other domains of moral judgments, and (c) sexual-sanctity associations compared to other disgust type-moral domain pairings.

Yves R. Simon explores moral virtue in this piece through identifying three moral positions common in modernity that attempt to substitute the traditional concept of virtue, as well as discussing the distinction between nature and use of sources of good or evil. He also discusses the distinctions between habits and opinions, as well as the virtue and science. He gives clear examples that make this book enjoyable for readers of all levels to understand moral virtue.

Metaphysical readings of Kant’s theoretical philosophy in the Critical period are ascendant. But their possibility assumes the possibility of existence- and real-possibility-judgments about things in themselves. I argue that Kant denies the latter possibility, so metaphysical readings have dubious prospects. First, I show that Kant takes existence- and real-possibility-judgments, as necessarily synthetic, to require a relation to sensible intuition. Second, I show that the most promising metaphysical readings can ultimately neither satisfy nor explain away that requirement for existence- and real-possibility-judgments (...) about things in themselves. I conclude with pessimistic reflections on the prospects for the metaphysical interpretive project. (shrink)

In Schmidt's experiments, only properties of actually produced movements systems are measured; in Fitts' experiments, external task parameters are measured too (target size and distance). Thus, the laws contain variables of different natures and cannot be reduced to each other even formally. These difference especially reveals itself in modeling: a model of variability can be simpler if it deals with the performance variables only. On the other hand, modeling Fitts' law, one should take into account not only the human effector (...) system but features of the experimental apparatus as well. These differences have not been sufficiently reflected in Plamondon & Alimi's target article. (shrink)

The proposal that there is an illusion of conscious will has been supported by findings that priming of stimulus location in a task requiring judgements of action-authorship can enhance participants’ experience of agency. We attempted to replicate findings from the ‘Wheel of Fortune’ task [Aarts, H., Custers, R., & Wegner, D. M. . On the inference of personal authorship: enhancing experienced agency by priming effect information. Consciousness and Cognition, 14, 439–458]. We also examined participants’ performance on this task in relation (...) to self-reported passivity experiences and hallucination-proneness. We found a significant effect of priming, with primes being found to increase the experience of agency. An interaction between gender and priming was also found, with priming enhancing feelings of agency in women but not in men. There were no significant correlations between levels of self-reported passivity experiences or hallucination-proneness and participants’ susceptibility to the priming effect on ratings of agency. Implications of these findings are discussed with regard to a prominent model of passivity experiences. (shrink)

COVID-19 presents many challenges, both clinical and philosophical. In this paper we discuss a major lacuna that COVID-19 revealed in our philosophy and understanding of medicine.

The voices and visions experienced by Emanuel Swedenborg remain a topic of much debate. The present article offers a reconsideration of these experiences in relation to changes in psychiatric practice. First, the phenomenology of Swedenborg's experiences is reviewed through an examination of his writings. The varying conceptualizations of these experiences by Swedenborg and his contemporaries, and by psychiatrists of later generations, are examined. We show how attempts by 19th- and 20th-century psychiatrists to explain Swedenborg's condition as the result of either (...) schizophrenia or epilepsy are unable to account for his experiences. We then demonstrate that the re-emergence of the 19th-century concept of `hallucinations in the sane' offers an alternative way to understand Swedenborg's experiences outside typical discourses of mental illness. Finally we argue that Swedenborg's experiences should be understood as exemplifying phenomena which we term `hallucinations without mental disorder', and investigate how conceiving of Swedenborg in this way can inform future research into the experience and clinical significance of hallucinations.
