Watching another person take actions to complete a goal and making inferences about that person's knowledge is a relatively natural task for people. This ability can be especially important in educational settings, where the inferences can be used for assessment, diagnosing misconceptions, and providing informative feedback. In this paper, we develop a general framework for automatically making such inferences based on observed actions; this framework is particularly relevant for inferring student knowledge in educational games and other interactive virtual environments. Our (...) approach relies on modeling action planning: We formalize the problem as a Markov decision process in which one must choose what actions to take to complete a goal, where choices will be dependent on one's beliefs about how actions affect the environment. We use a variation of inverse reinforcement learning to infer these beliefs. Through two lab experiments, we show that this model can recover people's beliefs in a simple environment, with accuracy comparable to that of human observers. We then demonstrate that the model can be used to provide real-time feedback and to model data from an existing educational game. (shrink)

Dans Risking together, Bryan et Rafferty pensent à la manière de la finance comportementale, mais ils pensent contre elle et inventent la Marxian behavioural finance. Ils montrent en quoi les ménages, amenés à penser à la manière de la finance dans leur vie quotidienne, sont devenus malgré eux un acteur clé du processus de production des produits dérivés. Les ménages sont désormais intégrés à la finance du côté offre, par la titrisation de leur dette mais aussi de leurs paiements, (...) et du côté demande par leur épargne. Il convient alors de préciser les enjeux systémiques de la boucle financière dans laquelle s’insèrent désormais les ménages, devenus collectivement absorbeurs nets de risque. Face à la toute-puissance d’une finance qui transfère les risques aux ménages, s’impose désormais l’institutionnalisation sociale du risque de défaut. (shrink)

The system of clinical ethics committees (CECs) in the United Kingdom is based on goodwill. No formal requirements exist as to constitution, membership, range of expertise or the status of their recommendations. Healthcare professionals are not obliged to use CECs where they exist, nor to follow any advice received. In addition, the make-up of CECs suggests that ethics itself may be under-represented. In most cases, there is one member with a training in ethics – the rest are healthcare professionals or (...) administrators, although a lawyer is generally also included in the membership. This begs the question as whether CECs can ‘do ethics’, as well whether or not they can take seriously the requirements of due process, formal justice and human rights. Moreover, the role of the patient in this system is opaque. (shrink)

Saunders has recently claimed that “identical quantum particles” with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black’s spheres, for example). Weakly discernible objects have all their qualitative properties in common but nevertheless differ from each other by virtue of (a generalized version of) Leibniz’s principle, since they stand in relations an entity cannot have to itself. This notion of weak discernibility has been criticized as question begging, but we (...) defend and accept it for classical cases likes Black’s spheres. We argue, however, that the quantum mechanical case is different. Here the application of the notion of weak discernibility indeed is question begging and in conflict with standard interpretational ideas. We conclude that the introduction of the conceptual resource of weak discernibility does not change the interpretational status quo in quantum mechanics. (shrink)

Critical literatures, and public discourses, on public health policies and practices often present fixated concerns with paternalism. In this paper, rather than focus on the question of whether and why intended instances of paternalistic policy might be justified, we look to the wider, real-world socio-political contexts against which normative evaluations of public health must take place. We explain how evaluative critiques of public health policy and practice must be sensitive to the nuance and complexity of policy contexts. This includes sensitivity (...) to the ‘imperfect’ reach and application of policy, leading to collateral effects including collateral paternalism. We argue that theoretical critiques must temper their demandingness to real-world applicability, allowing for the detail of social and policy contexts, including harm reduction: apparent knock-down objections of paternalism cannot hold if they are limited to an abstract or artificially-isolated evaluation of the reach of a public health intervention.

Although one can endorse the complexity of the data and processes that Phillips & Singer (P&S) review, their mathematical suggestions can be compared critically with cases in nonlinear psychophysics, where the theoretician is faced with analogous problems. Owing to P&S's failure adequately to recognise both the intricate properties of nonlinear dynamics in networks and the constraints of metabolic demands on the temporal generation of patterns in biological nets their conclusions fail to meet the problems they properly address.

Ausgehend von der, von Journalisten und Musikern immer wieder bemühten Metapher des 'Black CNN' wird versucht, das Potenzial der musikalischen Ausdrucksform des HipHop als Kommunikationsstruktur der Schwarzen Minderheit in den USA zu analysieren. Nach einer historisch-kulturellen Erläuterung, die sich mit der Tradition der Reflektion sozialer und politischer Aspekte in den unterschiedlichen musikalischen Äußerungen der Schwarzen Volksgruppe in den USA beschäftigt und schon ansatzweise die Bedeutung dieser Ausdrucksmöglichkeit im Kontext eines 'internal colonialsm' vor Augen führt, werden jene soziodemographischen Entwicklungen nachvollziehbar gemacht, (...) die sich als zentraler Kritikpunkt in den verbalen Artikulationen des HipHop widerspiegeln. Bestehende mediale Dysfunktionen hinsichtlich der Repräsentation von Angehörigen der Schwarzen Minderheit werden mit einem entsprechenden Fallbeispiel belegt. Vor dem theoretischem Hintergrund von 'cultural citizenship' - ein Konzept zur Bestimmung kultureller Teilhabe in der Mediengesellschaft -, werden 25 Textbeispiele, die sich auf HipHop-Veröffentlichungen von 1982 bis 2004 finden, auf ihre Übereinstimmung mit Indikatoren untersucht, die sich aus, den Medien zugeschriebenen, politischen und sozialen Funktionen ableiten lassen. Die angewandte Inhaltsanalyse lässt zahlreiche Entsprechungen erkennen, die sich zum Teil in komplexen, der Kritik- und Kontrollfunktion bzw. Integrationsfunktion der Medien zuzuordnenden Inhalten äußern. (shrink)

The universe, of which our domicile the planet Earth forms but a minuscule part, has an architecture that changes and has been changing in time. In other words, it has a history of evolution. Lack of experimental evidence denies us the knowledge of what the universe was like “at the time of its origin,” as discussed by Hubert Reeves in the preceding chapter. Neither do we know much about its geometry, simply because our observatories are concentrated, for all practical purposes, (...) vanishingly close to a single point in an immensity whose size can only be measured by the billions of years required by light to go from one extremity to another!

_ Source: _Volume 40, Issue 1, pp 104 - 115 It is intended in this study to present initial reliability and validity data for the Russian adaptation of the Multidimensional Inventory of Religious/Spiritual Well-being, as being related to personality factors and psychopathology. Therefore, the first version of the MI-RSWB-R was applied to a sample of 192 non-clinical subjects, together with the NEO Five Factor Inventory and the Symptom-Check-List. The original six-factor structure of the scale could be replicated for the MI-RSWB-R, (...) which also provides satisfying psychometric properties. In accordance with previous research the RSWB total score was linked to more favorable personality traits such as Extraversion, Openness to Experience, and Agreeableness, which was paralleled by substantial negative correlations with increased psychopathology. Our findings support the reliability and structural validity of the MI-RSWB-R as a standardized instrument for addressing the spiritual dimension in Russian populations. Further research in clinical surroundings is now recommended. (shrink)

Summary If action theory is to be relevant for the study of social phenomena, its scope has to be enlarged so as to include social structures. A hermeneutic theory of action, which draws on the thoughts of Gadamer, Merleau-Ponty, Ricoeur and Giddens, can meet this requirement. The hermeneutic concept of action, which emphasises the importance of tradition, style and rituals, demonstrates that action and structure presuppose and explain each other. The mutual relationship between action and structure is particularly clear in (...) theories of human development in the domain of psychology, psychotherapy and education. These theories can be used to construct a theory of social evolution, as has been developed by Habermas. By integrating structural, theoretical and critical points of view, a hermeneutic theory of action opens a perspective in which action theory and social theory might be successfully combined.

Being attentive to the needs of others, feeling responsible for each other, and taking care are necessary elements for the good life. Care, however, is a fragile activity: it is hard to predict its results. In this article, Homer's story of the Phaeacians bringing Odysseus back to Ithaca is interpreted to investigate what care could be when we admit the fragility of care. We consider two theoretical perspectives on care to interpret the story, namely Martha Nussbaum’s Aristotelian ethics, and the (...) Ethics of Care approach of authors like Ruddick, Sevenhuijsen, Tronto, Verkerk and others. In the first approach, the emphasis is on the attitude of care; in the second, on care as a social practice. Following Nussbaum, the caring response of the Phaeacians can be understood as an example of what Aristotle called ‘practical rationality’. The unexpected result of their care – they come into conflict with Poseidon – shows the fragility of human life and the tragic condition of humanity. According to Nussbaum, one should take responsibility for the fact that choosing for the one implies neglecting the other . From the perspective of Ethics of Care, the caring response is not so much the result of individual virtues; it is rather an element of a care practice that motivates people to act in conformity with basic values like solidarity and responsibility. The fragility of care is regarded as an ordinary quality of praxis and humanity rather than something essentially tragic. In the process of caring, misfortunes can never be totally prevented. Whenever they happen, they should be used as a way to learn and develop more adequate ways of handling the situation. The comparison of the two perspectives, both inspired by Aristotle's philosophy, gives rise to a richer view of the fragility of care. (shrink)
