The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has (...) the effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

The attitudes of patients' to consent have changed over the years, but there has been little systematic study of the attitudes of anaesthetists and surgeons in this process. We aimed to describe observations made on the attitudes of medical professionals working in the UK to issues surrounding informed consent.

While courts depend on expert opinions in reaching sound judgments, the role of the expert witness in legal proceedings is associated with a litany of problems. Perhaps most prevalent is the question of under what circumstances should testimony be admitted as expert opinion. We review the changing policies adopted by American courts in an attempt to ensure the reliability and usefulness of the scientific and technical information admitted as evidence. We argue that these admissibility criteria are best seen in a (...) dialectical context as a set of critical questions of the kind commonly used in models of argumentation. (shrink)

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

The Nature and Status of Critical Questions in Argumentation Schemes.

This research assessed how the performance and team skills of three-person teams working with an Intelligent Team Tutoring System on a virtual military surveillance task were affected by feedback privacy, participant role, task experience, prior team experience, and teammate familiarity. Previous work in Intelligent Tutoring Systems has focused on outcomes for task skill training for individual learners. As research extends into intelligent tutoring for teams, both task skills and team skills are necessary for good team performance. This work includes a (...) brief review of previous research on ITTSs, feedback, teams, and teamwork, including the recounting of two categories of a framework of teamwork performance, Communication and Cognition, which are relevant to the present study. This research examines the effects of an intelligent agent, as well as features of the team, its members, and the task being undertaken, on team communication and team situation awareness. Thirty-seven teams of three participants, each at their own computer running a multiplayer surveillance simulation, were given just-in-time private or public performance feedback during four 5-min trials. In the fourth trial, two of the three participants switched roles. Feedback type, teamwork experience, and teammate familiarity had no statistically significant effect on communication or team situation awareness. However, higher levels of role experience and task experience showed significant and medium-sized effects on communication performance. Results, based on performance data and structured interview responses, also revealed areas of improvement in future feedback design and a potential benchmark for feedback frequency in an action-oriented serious game-based ITTS. Among the conclusions are six design objectives for future ITTSs, establishing a foundation for future research on designing effective ITTSs that train interpersonal skills to nascent teams.

This article aims to contribute to the application of ethical frameworks to public health policy. In particular, the article considers the use of the Nuffield Council on Bioethics stewardship model, as an applied framework for the evaluation of evidence within public health policymaking. The ‘Stewardship framework’ was applied to a policy proposal to restrict marketing of food and beverages to children. Reflections on applying the stewardship model as a framework are provided. The article concludes that the questions used to apply (...) the stewardship model usefully introduced ethical considerations into the evidence review. However, the real value will likely come from the type of policy process within which the framework is used, identifying competing value positions and capturing local value requirements. (shrink)

Knowledge plays an important role in argumentation. Yet, recent work shows that standard conceptions of knowledge in epistemology may not be entirely suitable for argumentation. This paper explores the role of knowledge in argumentation, and proposes a notion of knowledge that promises to be more suitable for argumentation by taking account of: its dynamic nature, the defeasibility of our commitments, and the non-monotonicity of many of the inferences we use in everyday reasoning and argumentation.

In this paper we show how dialogue-based theories of argumentation can contribute to the construction of effective systems of dispute resolution. Specifically we consider the role of persuasion in online dispute resolution by showing how persuasion dialogues can be functionally embedded in negotiation dialogues, and how negotiation dialogues can shift to persuasion dialogues. We conclude with some remarks on how persuasion dialogues might be modelled is such a way as to allow them to be implemented in a mechanical or computerized (...) system of dialogue or dialogue management.

Chater & Loewenstein (C&L) ignore the long history by which social scientists have developed more nuanced and ultimately more helpful ways to understand the relationship between persons and situations. This tradition is reflected and advanced in a large literature on “wise” social–psychological or mindset interventions, which C&L do not discuss yet mischaracterize.

Strategies that motivate agrifood producers to adopt more sustainable practices are a critical component for a sustainable future. This case study examines farmer attitudes to a recently released New Zealand agricultural policy aimed at improving freshwater quality by restricting agricultural activities. Our study interprets interviews of nine individuals managing a range of dairy and sheep farming operations to explore how these farmers manage societal expectations of being a ‘good farmer’ in the context of the new regulations. Four themes were developed (...) to capture perceptions of participants: the vested interest of farmers in positive community engagement and being seen as a ‘good’ farmer; the need to manage farms prudently for future generations; the unique geographical and environmental conditions on each farm and their concerns about the lack of acknowledgment of differences across land types in New Zealand; and the unintended consequences of the new regulations for rural communities. Overall, the themes suggest that the way the policy was enacted conflicts with perceptions of a ‘good farmer’ and good farming practice, resulting in identity conflicts for the farming community and reduced motivation to adopt alternative practices.

The operation of the human intellect is twofold, however; first, simple perception, 'simple apprehension,' the 'simple gaze of indivisibles' and second, composition and division or judgment. In considering the principles of human knowledge it is therefore necessary to distinguish simple principles from complex principles or axioms. It is evident, however, that being is absolutely first of all complex as well as incomplex principles. "That which first falls under apprehension is being, the understanding of which is included in all things whatsoever (...) man apprehends. Therefore, the first indemonstrable principle is the same cannot be affirmed and denied at the same time, which is based on the constitutive intelligibility of being and non-being: and on this principle all others are based.".

According to St. Thomas Aquinas, "that which is said to exist through any nature is called a suppositum or subject of that nature. For example, that which has the nature of horse is said to be a subject or suppositum of equine nature." Subjects or supposita, moreover, occupy all the room there is in the Thomistic universe, since existence belongs properly only to individual subjects. These may be simple, as in the case of separate intelligences or composite as in the (...) case of inanimate and animate substances: "existence belongs properly to subsisting things, whether they be simple, as in the case of separate substances, or composite, as in the case of material substances. For the act of existing belongs properly to that which has existence: that is, to that which subsists in its own existence.". (shrink)

ObjectiveTo apply a socioecological approach to identify risk and protective factors across levels of the “sports-ecosystem,” which are associated with mental health outcomes among athletes in para-sports and non-para sports. A further aim is to determine whether para athletes have unique risks and protective factor profiles compared to non-para athletes.MethodsA cross-sectional, anonymous online-survey was provided to all categorized athletes aged 16 years and older, registered with the Australian Institute of Sport. Mental health outcomes included mental health symptoms, general psychological distress, (...) risky alcohol consumption and eating disorder risk. Risk and protective factors across multiple levels of the socioecological model, including individual, microsystem, exosystem and macrosystem level factors were assessed via self-report.ResultsA total of 427 elite athletes participated in the study. No significant differences in the rates of mental health problems were observed between para and non-para athletes. Both differences and similarities in risk and protective factor profiles were found across the multiple levels of the sports-ecosystem. Weak evidence was also found to support the hypothesis that certain risk factors, including experiencing two or more adverse life events in the past year, sports related concussion, high self-stigma, inadequate social support and low psychological safety conferred a greater risk for poorer mental health outcomes for para athletes in particular.ConclusionRisk factors occurring across various levels of the sports ecosystem, including individual, interpersonal and organizational level risk factors were found to be associated with a range of poorer mental health outcomes. The association between mental ill-health and certain risk factors, particularly those at the individual and microsystem level, appear to be greater for para athletes. These findings have important implications for policy and mental health service provision in elite sports settings, highlighting the need for more nuanced approaches to subpopulations, and the delivery of mental health interventions across all levels of the sports ecosystem.

After Husserl and Heidegger, phenomenology has attempted to push the reduction beyond the reference of objects to the performances effected by consciousness, or of beings to Being. First, a new level of the reduction comes forth in M. Henry's radical reduction of appearing to the appearing of appearing, and leads to the disclosure of a dimension in which no horizons are to be fulfilled because the superabundance of life holds sway. Secondly, according to H. Rombach, the phenomena decribed in the (...) first two levels are nothing but epiphenomena, and must be explained in terms of structures that emerge in a creative development. Reality brings forth something from itself, and we must take advantage of this contribution in order to obtain more than what is anticipated in our projects. Thirdly, J.-L. Marion advances a theory on saturated phenomena in order to account for phenomena that surpass the bounds outlined for them in the mere significational intentions because they show a surplus of intuition. The three trends lead respectively to an originary phenomenality, an outbreak of phenomena, and saturated phenomena. The article contends that they tend to come together because they link the third level of phenomenology to a reflection that turns on the duality between what appears and its appearing, and, in doing so, disclose a surplus with regard to three different aspects of the duality, i.e., appearing as such, the overall condition of what appears, or the appearing of some preeminent phenomena. Finally, some anticipations of these trends in Husserl's transcendental phenomenology are shown.Luego de Husserl y Heidegger, la fenomenología ha intentado llevar la reducción más allá de la referencia de los objetos a las operaciones efectuadas por la conciencia o de los entes al ser. En primer lugar, un nuevo nivel de reducción se manifiesta en la reducción radical propuesta por M. Henry para retroceder del aparecer al aparecer del aparecer, y conduce al descubrimiento de una dimensión en que no hay horizontes que puedan ser plenificados porque impera la sobreabundancia del la vida. En segundo lugar, según H. Rombach, los fenómenos descritos en los dos primeros niveles no son otra cosa que epifenómenos y tienen que ser explicados en términos de estructuras que emergen en un desarrollo creador. La realidad produce algo a partir de sí misma, y esta contribución debe ser aprovechada a fin de alcanzar más de lo anticipado en nuestros proyectos. En tercer lugar, J.-L. Marion presenta una teoría sobre los fenómenos saturados a fin de dar cuenta de aquellos casos que exceden los límites que les han sido delineados en las intenciones significativas vacías porque muestran una demasía de intuición. Las tres tendencias conducen respectivamente a una fenomenalidad originaria, a un estallido del fenómeno y a una saturación del fenómeno. El artículo sostiene que tienden a converger porque vinculan el tercer nivel de la fenomenología con una reflexión en torno de la dualidad entre lo que aparece y su aparecer, y que, al hacerlo, ponen de manifiesto una excedencia respecto de tres aspectos distintos de la dualidad, esto es, el aparecer en cuanto tal, la condición general de lo que aparece o la aparición de algunos fenómenos preeminentes. Finalmente, se indican algunas anticipaciones de estas tendencias en la fenomenología trascendental de Husserl. (shrink)

El artículo considera en primer lugar el papel asignado por Heidegger, en su análisis del viraje , al acontecimiento-apropiación como el punto medio entre el ser y el Dasein. En el carácter abismal de la oscilación entre el llamado del primero y la pertenencia del segundo reside la unidad originaria del tiempo-espacio que deja emerger ambos momentos hacia su separación. Esto permite a su vez el despliegue de un tiempo derivado y un orden para la medición. En segundo lugar, se (...) intentan encontrar puntos de vista similares en los análisis de Husserl sobre la temporalidad. Así, al abismo del ser corresponde un horizonte inicial originario; al tiempo-espacio abismal, la pretemporalización de una protohyle de la mano con kinestesias espacializantes; a la proyección del Dasein para captar la oscilación mediante una contraoscilación, el volverse del yo hacia la prototemporalización; a la separación del tiempo a partir del abismo, la constitución de las distinciones temporales; y a la derivación del orden del tiempo, la constitución del tiempo como forma. En tercer lugar, se expone la noción heideggeriana de decisión respecto de la pertenencia o no-pertenencia al ser a fin de criticar una parte componente de la historia del ser, esto es, la posición. En cuarto lugar, el artículo se ocupa de la noción husserliana de decisión en tanto ligada a la institución de un horizonte histórico. Por último, se destacan semejanzas y diferencias entre las nociones de acontecimiento-apropiación y presente viviente en la medida en que ambas desempeñan el mismo papel en la búsqueda de un nivel último que hace posible todo.

Un primer aspecto concierne a la praxis no-intencional y primaria del cuerpo propio. A ello se añade su condición de sostén para los valores sensibles de la comodidad y la salud, y de trampolín para valores espirituales cuyo nivel superior se encuentra en los valores éticos de la persona. Estos puntos de vista husserlianos encuentran nuevos desarrollos en la fenomenología: M. Henry pone el acento en un "yo puedo" pre-intencional, y Ricoeur describe el cuerpo propio como "fuente" de valores propios (...) y "resonador afectivo" de todos los valores, y a la vez esboza una concepción de la felicidad que incluye temples particulares de la corporalidad. Por último, Husserl considera la ofrenda del cuerpo propio a los valores espirituales en el sacrificio como la afirmación positiva de la vida de la humanidad. J. Patocka y E. Lévinas han desarrollado esta línea de pensamiento. A first aspect has to do with the non-intentional and primal praxis of the living body. To this is added its status as a support for the sensuous values of comfort and health and a springboard for spiritual values, the highest level of which lies in the ethical values of the person. These Husserlian views find new developments in phe-nomenology: M. Henry highlights a pre-intentional "I can", M. Scheler analyzes the relationship between hedonistic, vital, and spiritual values, and P. Ricoeur describes the living body both as the "source" ofits own proper values and the "affective resonator" of all values, and also outlines a view on happiness that encompasses particular bodily attunements. Finally, Husserl considers the offering of the living body to spiritual values in sacrifice as the positive assertion of humankind's life. J. Patocka and E. Lévinas have developed this line of thought. (shrink)

O artigo tenta diferenciar, caracterizar e ordenar diversas figuras da identidade na fenomenologia pós-husserliana. Em primeiro lugar, assinalam-se questões formuladas pela análise da ipseidade em Heidegger. Em segundo lugar, chama-se a atenção para duas tendências divergentes. Por um lado, Lévinas sustenta que uma fissão da identidade é o resultado da responsabilidade pelos outros, e Waldenfels desenvolve uma lógica da responsividade que questiona o autodesenvolvimento e a autopreservação. Por outro lado, Ricoeur sustenta que o ordenamento da vida num relato equivale a (...) uma identidade narrativa, e M. Henry oferece uma elaborada análise da vida interior como um processo de auto-afecção. Por último, tendo como base as distinções delineadas por X. Zubiri, afirma-se que existem fenômenos que oferecem um sustento a um sentido experiencial da identidade, e que isso pode se vincular à noção husserliana do eu como pólo, isto é, ao ponto de partida dos desenvolvimentos fenomenológicos.El artículo intenta diferenciar, caracterizar y ordenar diversas figuras de la identidad en la fenomenología post-husserliana.

First, issues raised by Heidegger's analysis of selfhood are pointed out. Secondly, attention is given to two divergent trends. On the one hand, Levinas contends that a fission of identity is the outcome of responsibility for others, and Waldenfels advances a logic of responsiveness that questions self-development and self-preservation. On the other hand, Ricoeur argues that the ordering of life in a story amounts to a narrative identity, and M. Henry affords an elaborate analysis of inward life as a process of self-affection. Finally, on the basis of distinctions outlined by X. Zubiri, it is contended that there are phenomena that uphold an experiential sense of identity. This can be linked to the Husserlian notion of an ego as a pole of acts, i.e., the starting point of phenomenological developments. (shrink)
