Purpose: This study aimed to develop a stroke effectiveness test in table tennis based on the temporal game structure to assess the ball speed and ball placement of the players, with a purpose to analyze its reproducibility and validity. Methods: Nineteen male table tennis players participated in this study. The test was performed twice during the first session and once during the second session to assess the intrasession and intersession reproducibility, respectively. Moreover, the test was examined on its ability to (...) discriminate between regional and local performance-level players and on the relationship between the test results and the table tennis performance to assess the discriminant and concurrent validity, respectively. In general, the test consisted of 11 simulated rallies of 2–5 balls with the effort and rest ratio of 0.5, and focused on attack with offensive strokes at defensive balls delivered by a robot randomly between the left and right positions on the table. Results: Ball speed, ball placement, and ball speed-ball placement index showed satisfactory reliability and agreement outcomes. Additionally, the Bland-Altman plots show the systematic error of the analyses closer to 0, and that most values were within the limits of agreements. Concerning validity analyses, regional players had higher scores of ball placement and ball speed-ball placement index as well as made fewer errors than local players. Moreover, ball placement, ball speed-ball placement index, and percentage error presented a strong and significant correlation with table tennis performance. However, ball speed was slightly different between the regional than local players and this variable was not related to table tennis performance. Conclusion: Our findings show evidences that the test is reproducible. Moreover, discriminant and concurrent validity are confirmed for ball placement and ball speed-ball placement index. (shrink)

Soccer players inescapably live under stress during the sportive career, and many real-life aspects of soccer situations operate in the ongoing performance. This study’s main objective was to elaborate the List of Stressors in Professional Indoor and Field Soccer, a self-report instrument designed to measure the impact of 77 soccer situations upon the sport performance. Participants were 138 indoor and field soccer players from the Brazilian Premier League. Each situation was evaluated on a 7-point scale, ranging from the most negative (...) to the most positive. Data were analyzed according to the players’ perception of the items: distress or eustress and its intensity, and after that, situations perceived as plus −1 and +1 were compared by time in which they were experienced and distributed among five categories established by the literature: Expectations about the Performance, Personal Factors, Competition Aspects, Training Demands, and Relationship with Significant People. Narratives of athletes’ experiences were also used to discuss the results. An Exploratory Structural Equation Modeling using Bi-factorial was employed to assess the factor structure. For the total participants, 49 situations were perceived as distress and 28 as eustress. Using the criteria established a priori, the distribution was among the five categories in the remaining 32 situations. Differences in perception between less and more experienced players were found in 11 situations. The results revealed that Brazilian professional soccer players experience various stressful situations. These events are important representations of environmental demands and could predict the performance as they are perceived as eustress or distress. Some of these stressful situations are inherent in sport and others adjacent to the sports system or environment. Coach pressure to win and conflicts with teammates are examples of stressors in-sport, family problems and disputes with press or fans are examples of stressors external to the team, also called peripheral opponents, and showed the relative social influence of significant others in soccer performance. We can conclude that the knowledge of the direction of a given stress situation has important practical implications in preparing athletes and helping them face the performance stressors that are part of soccer daily life.

What does it mean to devote yourself wholly to helping others? In Strangers Drowning, Larissa MacFarquhar seeks out people living lives of extreme ethical commitment and tells their deeply intimate stories; their stubborn integrity and their compromises; their bravery and their recklessness; their joys and defeats and wrenching dilemmas. A couple adopts two children in distress. But then they think: If they can change two lives, why not four? Or ten? They adopt twenty. But how do they weigh the (...) needs of unknown children in distress against the needs of the children they already have? Another couple founds a leprosy colony in the wilderness in India, living in huts with no walls, knowing that their two small children may contract leprosy or be eaten by panthers. The children survive. But what if they hadn't? How would their parents' risk have been judged? A woman believes that if she spends money on herself, rather than donate it to buy life-saving medicine, then she's responsible for the deaths that result. She lives on a fraction of her income, but wonders: when is compromise self-indulgence and when is it essential? We honor such generosity and high ideals; but when we call people do-gooders there is skepticism in it, even hostility. Why do moral people make us uneasy? Between her stories, MacFarquhar threads a lively history of the literature, philosophy, social science, and self-help that have contributed to a deep suspicion of do-gooders in Western culture. Through its sympathetic and beautifully vivid storytelling, Strangers Drowning confronts us with fundamental questions about what it means to be human. In a world of strangers drowning in need, how much should we help, and how much can we help? Is it right to care for strangers even at the expense of those we are closest to? Moving and provocative, Strangers Drowning challenges us to think about what we value most, and why. From the Hardcover edition. (shrink)

This paper reads Antigone from the perspective of the Chorus. Whereas most interpreters read Antigone from the perspective of Creon and Antigone’s respective laws, I maintain that the protagonists represent laws that are distinctly apolitical. Alternatively, I argue that the Chorus make the polis—past, present, and future—the center of their thought and action and are therefore uniquely political. Through close attention to the Chorus’s composition as a body that is both one and many at the same time, and by tracing (...) their evolving position throughout the action of the drama and in their choral odes, I argue that they model a reflective and political orientation to judgment rooted in plurality, tradition, and innovation.

When animals share decisions with others, they pool personal information, offset individual errors and, thereby, increase decision accuracy. This is termed ‘swarm intelligence.’ But what if those decisions involve conflicts of interest between individual decision-makers? Should animals share decisions with individuals whose goals are different from, and partially in conflict with, their own? A group decision model developed by Larissa Conradt and colleagues finds that, contrary to intuition, conflicting goals often increase both decision accuracy and the individual gains derived (...) from shared decisions. Thus, conflicts of interest, far from hampering effective decision making, can actually improve decision outcomes for all stakeholders, as long as they also have some goals in common. By contrast, conflict-free decisions shared by animals which all have the same goals are often surprisingly poor. (shrink)

This article investigates the notion of sensus communis as being introduced in the Critique of Judgment. I argue that, within the framework of Kant's philo- sophy, the general notion of a sensus communis, that is, a faculty that leads to sensuous and universal results, is paradoxical. An analysis of the theoretical sensus communis, understood as an awareness of the faculties' accord in cases of cognition, reveals that it is unclear why this faculty should amount to a sense. The aesthetic sensus (...) communis is the best candidate for a sensuous and communal faculty. However, I show that the communality of its results, that is, the community of the pleasure in the beautiful as being felt on the occasion of a given object, is insufficiently developed. (shrink)

The conception of disinterested pleasure is not only central to Kant’s theory of beauty but also highly influential in contemporary philosophical discourse about beauty. However, it remains unclear, what exactly disinterested pleasure is and what role it plays in experiences of beauty. This volume sheds new light on the conception of disinterested pleasure from the perspectives of both Kant scholarship and contemporary aesthetics. In the first part, the focus is on Kant’s theory of beauty as grounded on the conception of (...) disinterested pleasure. In the second part, disinterested pleasure is investigated in the light of contemporary debates on beauty. The third part is dedicated to the relation of theories of disinterested pleasure to the meta-aesthetical debate between realism and anti-realism. The volume clarifies the meaning, role, and implications of one of the most influential conceptions in traditional as well as contemporary approaches to beauty. (shrink)

This paper presents Integrated Information Theory (IIT) 4.0. IIT aims to account for the properties of experience in physical (operational) terms. It identifies the essential properties of experience (axioms), infers the necessary and sufficient properties that its substrate must satisfy (postulates), and expresses them in mathematical terms. In principle, the postulates can be applied to any system of units in a state to determine whether it is conscious, to what degree, and in what way. IIT offers a parsimonious explanation of (...) empirical evidence, makes testable predictions, and permits inferences and extrapolations. IIT 4.0 incorporates several developments of the past ten years, including a more accurate translation of axioms into postulates and mathematical expressions, the introduction of a unique measure of intrinsic information that is consistent with the postulates, and an explicit assessment of causal relations. By fully unfolding a system's irreducible cause-effect power, the distinctions and relations specified by a substrate can account for the quality of experience. (shrink)

Research indicates that consumers are particularly concerned about the safety of meat. More highly processed meat is perceived as more unsafe than fresh or natural meats, i.e., consumers trust processed meat less. This paper studies the relationship between perceived trust and day-to-day purchase behavior for meat, giving special attention to the degree of meat processing. Controlling for trust in food chain actors and demographic and socio-economic variables, actual meat purchases of Canadian households are linked to answers from a commissioned food (...) attitudes survey completed by the same households. Expenditures for processed and total meat (but not for fresh meat) are significantly different by three levels of trust in the food industry. Consumer with the lowest trust levels consume less (especially of processed meat) compared to those with higher trust levels. However, in a multivariate setting, trust shows no effect on fresh or processed meat purchases with or without demographic and socio-economic control variables, suggesting that the impact of trust on meat purchases is only small. However, the low trusting consumer segment could potentially be a target for marketing strategies focused on reputation and quality to increase sales in this particular group. (shrink)

Em diversos momentos de sua trajetória filosófica Deleuze recorre à Leibniz. Num primeiro momento para pensar a síntese ideal da diferença em Diferença e Repetição, não sem antes ter tecido duras críticas ao infinito leibniziano. Neste artigo nos consagraremos a este momento. Buscaremos demonstrar a importância do conceito de causa imanente de Espinosa, assim como do princípio de razão suficiente e de suas funções no pensamento leibniziano. Apresentaremos a crítica deleuziana do conceito de identidade em Leibniz e a interpretação do (...) cálculo diferencial que serve de base para a construção do processo de determinação conceitual, ou seja, para a síntese ideal da diferença, tema do capítulo IV de Diferença e repetição. A relevância deste artigo está na tentativa de demonstrar que a tese da univocidade do ser não pode ser compreendida sem sua contrapartida, a equivocidade dos sentidos através dos quais o ser se diz e em explorar consequências desta tese para a reconstrução deleuziana da relação empírico-transcendental. Procuraremos demonstrar que Deleuze precisa recorrer a Leibniz para pensar a diferença ilimitada. (shrink)

O objetivo central deste artigo é desenvolver a ideia sobre a utilidade ética da pecuária industrial com ênfase nas doenças zoonóticas a partir do referencial teórico de Peter Singer. Com o aumento da demanda em âmbito global por proteína animal, foram empreendidos novos métodos de manejo que submetem os animais a situações opostas ao bem-estar. Além do mais, essas mudanças são responsáveis pela ascensão das doenças zoonóticas. Desse modo, o presente trabalho trata-se da revisão bibliográfica dos livros Ética Prática e (...) Libertação Animal do Peter Singer e artigos buscados nas plataformas: Scielo, Elsevier e Google Acadêmico. Assim, conclui-se que a pecuária industrial possui uma utilidade duvidosa dentro dos limites da pesquisa porque gera maior desprazer do que prazer. (shrink)

In his theory of beauty, Kant introduces the free and harmonious play of the faculties as a kind of judging. This judging should precede the pleasure in the beautiful. But being the determining ground of the judgement of taste, the pleasure should precede the judgement. Regarding this problem, two opposing models have been proposed: Paul Guyer's ‘two-acts model’ and Hannah Ginsborg's ‘one-act model’. I propose a third model that, I argue, resolves the difficulty and does not fall prey to the (...) problems of the other two resolutions: the ‘subsumption model’, according to which the pleasure is followed by a subsumption under the concept ‘beautiful’.

Resumo: A partir de uma apresentação do contexto político e social no interior do qual a obra de Guattari se insere, buscamos definir o debate político francês da década de 60, no campo do marxismo, sobretudo do materialismo histórico em torno da questão do sujeito da história. O objetivo deste artigo é explicitar as razões que levam Guattari a romper com o estruturalismo, representado na psicanálise por Lacan e no marxismo por Althusser. A relevância deste texto está na apresentação do (...) conceito de máquina, que se define em oposição ao conceito de estrutura e que, unindo história e inconsciente, visa a traçar o espaço de emergência de um sujeito da história, de um sujeito político.: From a presentation of the political and social context within which Guattari’s work fits in, we seek to define the French political debate of the 1960s in the field of Marxism - especially historical materialism - on the question of the subject of history. The purpose of this article is to explain the reasons that lead Guattari to break with structuralism, represented in psychoanalysis by Lacan and Marxism by Althusser. The relevance of this article lies in the presentation of the concept of machine, which is defined in opposition to the concept of structure and that, joining history and unconscious, aims to trace the emergence space of a subject of history, of a political subject.

Resumo Procuramos demonstrar, a partir de uma relação entre a noção adorniana de estilo tardio e obras tardias de Deleuze - sobretudo L’épuisé, que trata da obra igualmente tardia de Beckett para a televisão - que há no pensamento deleuziano uma importante reflexão sobre a morte. Procuramos salientar a presença desta ideia e diferenciar a morte da noção de negativo, criticada pelo autor. Uma vez traçada a natureza desta reflexão, pretendemos questionar sua relevância no estudo da obra de Beckett.In this (...) article, we sought to demonstrate that there is in Deleuze’s philosophy an original reflection on death, which cannot be exhausted by an idea of negativity so common inside the Hegelian tradition. To achieve this objective a relation will be draw between Adornian notion of late style and Deleuze's late works - especially L'épuisé, We seek to highlight the presence of this idea of death and to differentiate it from the notion of negative so criticized by Deleuze. Once drawn the nature of this reflection, we intend to question its preponderance in Beckett's late works for television. (shrink)

To be true of every experience, the axioms of Integrated information theory are necessarily basic properties and should not be “over-psychologized.” Information, for example, merely asserts that experience is specific, not generic. It does not require “access.” The information a system specifies about itself in its current state is revealed by its unfolded cause–effect structure and quantified by its integrated information.

This book throws new light on the way in which the Internet impacts on democracy. Based on Jürgen Habermas' discourse-theoretical reconstruction of democracy, it examines one of the world's largest, most diverse but also most unequal democracies, Brazil, in terms of the broad social and legal effects the internet has had. Focusing on the Brazilian constitutional evolution, the book examines how the Internet might impact on the legitimacy of a democratic order and if, and how, it might yield opportunities for (...) democratic empowerment. The book also assesses the ways in which law, as an institution and a system, reacts to the changes and challenges brought about by the Internet: the ways in which law may retain its strength as an integrative force, avoiding a 'virtual' legitimacy crisis.

In § 60 of the Critique of Judgment, entitled ‘On the doctrine of method of taste,’ Kant suggests that the study of so-called humaniora (ancient Roman and Greek literature) will help one to become a good artist. I will argue that a proper, namely emotional, engagement with humaniora will further the two components of humanity in ourselves: the feeling of sympathy and the ability to communicate feelings. I will discuss two options of how a strengthening of these two components might (...) contribute to the creation of good artworks: it will help one to create artworks that arouse the universal communicable pleasure in the beautiful, or it will help one to create artworks that arouse sympathetic feelings. Siding with the latter option, I will argue that emotions can contribute to the enlivening of aesthetic ideas and, thus, to good art. (shrink)

Decades of feminist research has revealed the dismal labor conditions for women in global supply chains. Given this reality, why does Walmart use women in its supply chain as icons of female empowerment? Combining the Marxist notion of a “spatial fix” with a feminist analysis of symbolic resources, we develop the concept of a “gender fix” to understand a growing field of corporate programs that use women as symbolic resources to restore the image of firms as ethical actors. The gender (...) fix encompasses a wide range of corporate empowerment strategies to capture a broad pattern of action. A second term is necessary to situate Walmart’s particular empowerment strategy within its corporate positioning as leader of a vast supply chain network. We identify Walmart’s particular empowerment strategy as “outsourcing feminism.” Walmart’s use of the outsourcing feminism strategy stems from its commanding position in supply chains, which allows it to extract a symbolic surplus from women business owners from whom it sources products. When Walmart argues that it uplifts these women, its strategy targets the consumer end of the supply chain, emphasizing sourcing practices that promote a racially diverse, selfless, and middle-class femininity. In so doing, Walmart deflects attention from the treatment of women in other segments of its supply chain (e.g., its stores and factories). (shrink)

This is a persona] account of an Aboriginal woman who went through the education system in Australia to obtain finally her law degree. Aboriginal people experience many hurdles in the education system. Many Aboriginal children feel alienated within the legal system which until recently focused on a colonial history of Australia, ignoring the experiences, indeed the presence, of indigenous people in Australia. The Australian government had a policy of not educating Aboriginal people past the age of 14. The author was (...) one of the first generation that could go straight from high school to university. She speaks of the debt she feels towards the generations of her people that fought for her right to access to higher education. The author went on to become the first Aboriginal person to be accepted into Harvard Law School which brought different personal challenges and allowed for reflection on comparisons of the sensitivity towards race in both education systems. When the author returned to Australia, she took a position teaching at the University of New South Wales. She had to come to terms with working within a system that she had felt alienated within as a student. Her position at the front of the class has created a sense of empowerment that she can pass on to her Aboriginal and female students. (shrink)

Theories of cognitive development must address both the issue of how children bring their knowledge to bear on behavior in‐the‐moment, and how knowledge changes over time. We argue that seeking answers to these questions requires an appreciation of the dynamic nature of the developing system in its full, reciprocal complexity. We illustrate this dynamic complexity with results from two lines of research on early word learning. The first demonstrates how the child's active engagement with objects and people supports referent selection (...) via memories for what objects were previously seen in a cued location. The second set of results highlights changes in the role of novelty and attentional processes in referent selection and retention as children's knowledge of words and objects grows. Together this work suggests that understanding systems for perception, action, attention, and memory, and their complex interaction, is critical to understand word learning. We review recent literature that highlights the complex interactions between these processes in cognitive development and point to critical issues for future work. (shrink)

Morin envisions the adaptive landscape of graphic codes as an unfertile valley where writing rises as an isolated peak that humans managed to reach only on four occasions throughout all of history. By exploring the different paths to cultural convergence, we suggest an alternative landscape occupied by a mountain range of visual art systems. We conclude that graphic communication through visual art worked well enough to render writing contingent but not necessary in most cases.

The identification of facial expressions is critical for social interaction. The ability to recognize facial emotional expressions declines with age. These age effects have been associated with differential age-related looking patterns. The present research project set out to systematically test the role of specific facial areas for emotion recognition across the adult lifespan. Study 1 investigated the impact of displaying only separate facial areas versus the full face on emotion recognition in 62 younger and 65 middle-aged adults. Study 2 examined (...) if wearing face masks differentially compromises younger versus middle-aged to older adults’ ability to identify different emotional expressions. Results of Study 1 suggested no general decrease in emotion recognition across the lifespan; instead, age-related performance seems to depend on the specific emotion and presented face area. Similarly, Study 2 observed only deficits in the identification of angry, fearful, and neutral expressions in older adults, but no age-related differences with regards to happy, sad, and disgusted expressions. Overall, face masks reduced participants’ emotion recognition; however, there were no differential age effects. Results are discussed in light of current models of age-related changes in emotion recognition. (shrink)

The concept of substance is considered fundamental in order to understand chemistry and other related concepts, but many problems have been reported about its learning process. Considering the importance of textbooks in the training of chemistry teachers, this study aimed to identify the concepts of substance in general chemistry textbook glossaries. In addition, the study assessed the concepts of substance in relation to other chemical concepts and, when available, compared them with the concepts established by the IUPAC. The methodology employed (...) was content analysis and the results showed that concepts and statements related to the term ‘substance’ are different in the general chemistry textbooks analyzed. They also differ from those stated by IUPAC. Furthermore, it was found that many concepts are dependent on the concept of substance. It is concluded that there must be a greater effort from the community of chemists and the teaching of chemistry in the search for conceptual uniformity to reduce the problems of conceptual understanding.

The paper deals with the general peculiarities of numerals. Cases where the sense of numeral cannot simply be explained by the idea of counting, of number, or of order are considered. Special types of texts folklore on the one band, propaganda on the other hand - are analyzed. For the latter the examples from two Soviet central official newspapers - Pravda and lzvestija of May 1986 have been chosen. These texts partially reflect common stylistic features of Soviet propagandistic discourse of (...) the "period of stagnation"; their specificity is caused by the special situation, which obtained in the country in those days - the catastrophe in the atomic power station in Chemobyl. It is claimed that all the considered examples reflect several aspects of meaning of numerals contained in their general semantics. Thus, the development of the evaluative meaning is explained by the semantics of degree contained in the numerals. These data contribute to Frege's idea of relativity of number, but from another, purely linguistic, point of view. (shrink)
