O Método de Gardner – um método por dígrafos para a Silogística – implementa a concepção de proposições categóricas como expressões de subordinação e de não-subordinação entre pares de conceitos; nele, a representação das proposições universais é mais complexa do que a representação das proposições particulares. Neste trabalho desenvolverei uma implementação da Silogística na qual as proposições categóricas são expressões de instanciação e de não-instanciação de pares de conceitos. Adaptarei o Sistema Beta dos Grafos Existenciais de Peirce ao Método (...) de Gardner. Essa adaptação tem o mérito de igualar a complexidade da representação das proposições categóricas, mas introduz outros inconvenientes. (shrink)

Big Ideas for Little Kids includes everything a teacher, a parent, or a college student needs to teach philosophy to elementary school children from picture books. Written in a clear and accessible style, the book explains why it is important to allow young children access to philosophy during primary-school education. Wartenberg also gives advice on how to construct a "learner-centered" classroom, in which children discuss philosophical issues with one another as they respond to open-ended questions by saying whether they agree (...) or disagree with what others have said.

Genetic moderation of experience of reward in response to environmental stimuli is relevant for the study of many psychiatric disorders. Experience of reward, however, is difficult to capture, as it involves small fluctuations in affect in response to small events in the flow of daily life. This study examined a momentary assessment reward phenotype in relation to the catechol-O-methyl transferase (COMT) Val158Met polymorphism. A total of 351 participants from a twin study participated in an Experience Sampling Method procedure to collect (...) daily life experiences concerning events, event appraisals, and affect. Reward experience was operationalized, as the effect of event appraisal on positive affect (PA). Associations between COMT Val 158Met genotype and event appraisal on the one hand and PA on the other were examined using multilevel random regression analysis. Ability to experience reward increased with the number of ‘Met’ alleles of the subject, and this differential effect of genotype was greater for events that were experienced as more pleasant. The effect size of genotypic moderation was quite large: subjects with the Val/Val genotype generated almost similar amounts of PA from a ‘very pleasant event’ as Met/Met subjects did from a ‘bit pleasant event’. Genetic variation with functional impact on cortical dopamine tone has a strong influence on reward experience in the flow of daily life. Genetic moderation of ecological measures of reward experience is hypothesized to be of major relevance to the development of various behavioral disorders, including depression and addiction.

Issues of reliability are claiming center-stage in the epistemology of machine learning. This paper unifies different branches in the literature and points to promising research directions, whilst also providing an accessible introduction to key concepts in statistics and machine learning---as far as they are concerned with reliability.

This paper reports a Contingent Valuation application to estimate the non-market costs and benefits of hydro scheme developments in an Icelandic wilderness area. A deliberative group -based approach, called Market Stall, is compared to a control group consisting of conventional in-person interviews, in order to investigate flaws of Contingent Valuation, such as poor validity and protest responses. Perceived property rights suggested the use of willingness-to-accept in compensation for wilderness loss and willingness-to-pay for hydro scheme benefits. The study is novel as (...) it applies participant behaviour observation to gain insights into the shortcomings of conventional data collection modes. Main drawbacks with in-person interviews were found to be low motivation, standardised information and time pressure which hindered individuals from carefully considering their preferences. Market Stall performed better in the study: welfare estimates were more easily explained by socio-economic variables, the non-response rate was lower, and respondents were more engaged. Our research findings also suggest that participant behaviour can be used to supplement conventional validity tests. (shrink)

Wir reden gelegentlich von Kompromissen, die wir mit uns selbst schließen. Aber ist diese Rede angemessen oder gar berechtigt? Schließlich lassen sich wesentliche Merkmale von Kompromissen mit anderen nicht auf das Selbstverhältnis einer Person übertragen. Dennoch kann sich die Rede unter gewissen Umständen als sinnvoll erweisen. Der Artikel gibt Kriterien dafür an und stellt sich vor allem die Frage, ob und in welcher Hinsicht solche selbstbezüglichen Kompromisse eine Gefahr für die Integrität der Person darstellen.

The words quoted above distill the common secular conception of death. If we decline the traditional religious reassurances of an afterlife, or their fuzzy new age equivalents, and instead take the hard-boiled and thoroughly modern materialist view of death, then we likely end up with Gonzalez-Cruzzi. Rejecting visions of reunions with loved ones or of crossing over into the light, we anticipate the opposite: darkness, silence, an engulfing emptiness. But we would be wrong.

As time-shifting technologies and digital convergence are facilitating and encouraging increasingly individualized and personalized television viewing practices, the social role and function of traditional linear television might be changing as well. Through empirical audience research, using TV diaries and interviews, this article investigates the social dimensions of engaged viewers’ reception of TV drama and explores how audiences themselves experience contemporary television as a social medium. The qualitative analysis reveals three social dimensions in viewers’ engagement with TV drama and indicates that (...) television is generally still perceived as a social medium. Time-shifting technologies do not only fracture audiences, they also create new opportunities for social connections with peer viewers. (shrink)

This paper is an exposition and evaluation of the Agustín Rayo's views about the epistemology and metaphysics of mathematics, as they are presented in his book The Construction of Logical Space.

Here, we focus on the underexplored fictional relevance of videogame glitches. For this purpose, we will make use philosophical theories on fiction, as well as standard suggestions about how best to deal with unintended errors within fiction. Focusing on glitches like that of Red Dead Redemption’s "manimals", we argue that glitches, more than any kinds of mistakes in traditional, non-interactive fictions, can actually have a significant influence on the fictional worlds of the work in which they appear. In particular, we (...) will show that some glitches generate new fictional content without this content being intended by a videogame’s creators, and will offer practical ways for dealing with the inconsistencies that inevitably accompany such glitch-generated fictions.

This volume is a study of the influence of Timaeus on the development of Western cosmology in three axial periods of European culture: Late Antiquity, Middle Ages and Renaissance.

Examines how the educations of America's first four presidents, and in particular their scholarly devotion to ancient Greek and Roman classics, informed the beliefs and ideals that shaped the nation's constitution and government.

As artefacts, the worlds of digital games are designed and developed to fulfil certain expressive, functional, and experiential objectives. During play, players infer these purposes and aspirations from various aspects of their engagement with the gameworld. Influenced by their sociocultural backgrounds, sensitivities, gameplay preferences, and familiarity with game conventions, players construct a subjective interpretation of the intentions with which they believe the digital game in question was created. By analogy with the narratological notion of the implied author, we call the (...) figure to which players ascribe these intentions ‘the implied designer’. In this article, we introduce the notion of the implied designer and present an initial account of how appreciators ascribe meaning to interactive, fictional gameworlds and act within them based on what they perceive to be the designer’s intentions.

Gemeinschaft und Gesellschaft sind zentrale Begriffe der Sozialphilosophie und der politischen Philosophie. Die Untersuchung der Begriffe Gemeinschaft und Gesellschaft sowie ihres Verhältnisses zueinander erfolgt in der vorliegenden Arbeit im Rahmen der philosophischen Frage nach Möglichkeit, Konstitution und Kritik des Sozialen. In ihrer Studie wendet sich Nele Schneidereit gegen die tradierte Opposition von Gemeinschaft und Gesellschaft. Gemeinschaft und Gesellschaft beschreiben zwei zu unterscheidende Aspekte eines in sich vermittelten Zusammenhangs. Diese zunächst negativ-traditionskritische These wird ergänzt durch die positiv-systematische These, dass Gemeinschaft (...) und Gesellschaft als Grundbegriffe einer kritischen Sozialphilosophie zu begreifen sind, deren Kern der Begriff einer politischen Gemeinschaft ist. Dabei entfaltet die Autorin ihre Argumentation vor allem entlang der Schriften von Ferdinand Tönnies und Helmuth Plessner. (shrink)

Nos deteremos aqui sobre a crítica de Matthew Kramer em relação à interpretação de Quentin Skinner sobre o conceito de “liberdade” em Hobbes contida em seu artigo “On the Unavoidability of Actions: Quentin Skinner, Thomas Hobbes, and the Modern Doctrine of Negative Liberty” (2001). Nele, Kramer trata do então crescente interesse do projeto intelectual de Skinner pelo pensamento hobbesiano, algo já evidenciado desde a publicação de seu livro Liberdade Antes do Liberalismo (1998). Kramer toma como referência central de (...) sua resposta o artigo de Skinner intitulado “Thomas Hobbes on the Proper Signification of Liberty”, criticando a sua posição e contrastando com algumas de suas próprias ideias sobre “liberdade” e “não-liberdade”. Através dessas considerações, Kramer reavalia a noção da liberdade em Hobbes, tomando-a como o protótipo liberal da liberdade negativa por excelência, demonstrando assim os supostos equívocos contidos na interpretação de Skinner sobre ela. Buscamos defender aqui, contudo, que a proposta interpretativa de Kramer carece da devida fundamentação metodológica que correlaciona o neorrepublicanismo de Skinner no campo da filosofia política com certos princípios oriundos de sua historiografia que não são devidamente considerados pelo primeiro. A sua crítica estaria, assim, comprometida por uma abordagem desconectada do pensamento e das intenções de Hobbes enquanto um agente político inserido em um determinado contexto linguístico e social, quadro que seria posteriormente resgatado de maneira primorosa por Skinner em seu estudo Hobbes and Republican Liberty (2008).

What do players of videogames mean when they say they want to shoot zombies? Surely they know that the zombies are not real, and that they cannot really shoot them, but only control a fictional character who does so. Some philosophers of fiction argue that we need the concept of imaginative desires to explain situations in which people feel desires towards fictional characters or desires that motivate pretend actions. Others claim that we can explain these situations without complicating human psychology (...) with a novel mental state. Within their debates, however, these scholars exclusively focus on non-interactive fictions and children’s games of make-believe. In this paper, I argue that our experience of immersive, interactive fictions like videogames gives us cause to reappraise the concept of imaginative desires. Moreover, I describe how i-desires are a useful conceptual tool within videogame development and can shed new light on apparently immoral in-game actions. (shrink)

To realize a successful and collaborative interaction between human and robots remains a big challenge. Emotional reactions of the user provide crucial information for a successful interaction. These reactions carry key factors to prevent errors and fatal bidirectional misunderstanding. In cases where human–machine interaction does not proceed as expected, negative emotions, like frustration, can arise. Therefore, it is important to identify frustration in a human–machine interaction and to investigate its impact on other influencing factors such as dominance, sense of control (...) and task performance. This paper presents a study that investigates a close cooperative work situation between human and robot, and explore the influence frustration has on the interaction. The task for the participants was to hand over colored balls to two different robot systems. The robot systems had to throw the balls into appropriate baskets. The coordination between human and robot was controlled by various gestures and words by means of trial and error. Participants were divided into two groups, a frustration- and a no frustration- group. Frustration was induced by the behavior of the robotic systems which made errors during the ball handover. Subjective and objective methods were used. The sample size of participants was N = 30 and the study was conducted in a between-subject design. Results show clear differences in perceived frustration in the two condition groups and different behavioral interactions were shown by the participants. Furthermore, frustration has a negative influence on interaction factors such as dominance and sense of control. The study provides important information concerning the influence of frustration on human–robot interaction for the requirements of a successful, natural, and social HRI. The results are discussed in favor of how a successful und effortless interaction between human and robot can be realized and what relevant factors, like appearance of the robot and influence of frustration on sense of control, have to be regarded.
