This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

The Baby Care Scale was designed to assess the involvement of father in infant care during pregnancy and the postpartum period. This study aimed to examine the psychometric characteristics of the BCS – antenatal and BCS – postnatal versions. A sample of 100 primiparous fathers completed the BCS-AN and/or the BCS-PN and self-reported the measures of anxiety and depressive symptoms and of father–infant emotional involvement during pregnancy and the postpartum period, respectively. Good internal consistency was found for both the BCS-AN (...) and the BCS-PN. A two-factor model was found for both versions of the instrument: household tasks and infant care tasks. The BCS-AN and BCS-PN subscales revealed good internal consistency. Higher scores on the BCS-AN predicted higher scores on the BCS-PN. Significant associations were found among the BCS, depressive and anxiety symptoms, and father–infant emotional involvement, revealing good criterion validity. This study suggested that both the BCS-AN and the BCS-PN are reliable multidimensional self-report measures that assess the involvement of father in infant care during pregnancy and the postpartum period.

In this introduction we present Patrick Duffley's book Linguistic Meaning meets Linguistic Form, as well as the contributions that each scholar has brought into the debate on linguistic meaning and form. They deal with semantic and foundational issues regarding a sign-based approach to meaning.

In this paper we suggest that Duffley’s sign-based semantics rests on two main claims: a methodological one and an ontological one. The methodological one is the analysis of corpora and the ontological one is the postulate of mental content. By adopting a linguistic enactivist perspective with a Wittgensteinian twist, we endorse Duffley’s methodological claim and suggest that a sign-based semantics doesn’t have to rely on mental content if it takes into account the conception of meaningful material engagement in cognitive archeology (...) and its development into sign-using as an enactive capacity.

This paper responds to the contributions by Alexander Bird, Nathan Wildman, David Yates, Jennifer McKitrick, Giacomo Giannini & Matthew Tugby, and Jennifer Wang. I react to their comments on my 2015 book Potentiality: From Dispositions to Modality, and in doing so expands on some of the arguments and ideas of the book.

Este livro é uma apresentação das teorias e sistemas da psicologia contemporânea articuladas numa visão de conjunto em que podem ser estabelecidas suas afinidades e incompatibilidades. O texto compõe-se de doze capítulos. O primeiro trata de como se formou o campo específico da psicologia. No segundo, mostra-se como este espaço foi ocupado por diferentes doutrinas cientificistas, românticas e pós-românticas. Os demais capítulos apresentam as matrizes do pensamento psicológico e as teorias de surgimento.

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

Ulrich Beck's best selling Risk Society established risk on the sociological agenda. It brought together a wide range of issues centering on environmental, health and personal risk, provided a rallying ground for researchers and activists in a variety of social movements and acted as a reference point for state and local policies in risk management. The Risk Society and Beyond charts the progress of Beck's ideas and traces their evolution. It demonstrates why the issues raised by Beck reverberate widely throughout (...) social theory and covers the new risks that Beck did not foresee, associated with the emergence of new technologies, genetic and cybernetic. The book is unique because it offers both an introduction to the main arguments in Risk Society and develops a range of critical discussions of aspects of this and other works of Beck. (shrink)

Szabó follows Heim in viewing familiarity, rather than uniqueness, as the essence of the definite article, but attempts to derive both familiarity and uniqueness implications pragmatically, assigning a single semantic interpretation to both the definite and indefinite articles. I argue that if there is no semantic distinction between the articles, then there is no way to derive these differences between them pragmatically.

La doctrine philosophique préparée par la révolution copernicienne ne semble pas faire sa part au politique. En effet, le système de la philosophie se divise en liberté et nature, le politique ne pouvant être réduit ni à l'autre. Cependant, on peut dégager l'originalité du politique chez Kant précisément à partir de cette difficulté d'accommodation. On verra alors s'esquisser un rapprochement stylistique entre Kant et l'idéalisme allemand: dans les deux cas, l'intelligibilité du présent est rapportée à la médiation entre normativité et (...) expérience. It seems that there is no place to politics in the philosophical doctrine orchestrated by the Copernican revolution. Indeed, none of the two parts of the philosophical system — nature and freedom — can alone give a satisfactory account of politics. However, it is arguable that by reflecting on this topical difficulty one could detect the originality of Kant's approach to the political. By proceeding in this way one is also able to recognize a stylistic nearness between Kant and the philosophers of German Idealism: in both cases, the intelligibility of the present is related to the mediation between normativity and experience.

O feminismo interseccional tem sido apontado como uma importante teoria na compreensão de como as opressões de gênero, classe e raça dentre outras, se relacionam entre si e interferem na vida de cada mulher, que acaba assim por experimentar a opressão de gênero a partir de um ponto de vista único. Além disso, a atuação de coletivos feministas tem sido fundamental na vida de mulheres, como espaços de empoderamento e de luta em prol de uma sociedade menos opressiva. Assim, apresentamos (...) nesse trabalho o processo de adoção do feminismo interseccional como ferramenta teórico-metodológica por um coletivo feminista da Bahia, Brasil. Para tanto, realizamos um relato das atividades desenvolvidas pelo grupo entre os anos de 2013 e 2017. Foi possível identificar o forte vínculo afetivo estabelecido entre as companheiras e como o discurso interseccional tem sido importante nesse processo e nas ações do Coletivo como um todo. Constatou-se, assim, que a utilização deste referencial pode ser poderosa no sentido de contribuir para diálogos mais inclusivos e assim mais transformadores. Corroborando, ainda, com a ideia da extrema relevância da articulação entre o feminismo acadêmico e a ação política, além de destacar os desafios da consolidação de coletivos que nascem no âmbito acadêmico.

A investigação transcendental pressupõe um exercício de abstração, que na Crítica da Razão Pura se aplica ao conhecimento da experiência. Sua bipartição em dois modos-de-representação, contudo, levanta duas dificuldades à teoria da objetividade kantiana: como conciliar os, elementos separados pela análise e como assegurar a legitimidade da abstração sobre o conhecimento empírico.

Embodied approaches to human cognition emphasize the role of the body in processes of linguistic comprehension and production. Several empirical studies have presented support to these approaches. The recent linguistic enactivist approach to cognition stands out for suggesting that we have to deepen our concept of the body. In this context, we present: 1) neurological and psychological evidence supporting the claim that concepts are embodied; 2) two theoretical approaches to embodied cognition in the cognitive sciences: the grounded cognition approach, and (...) one approach based on dynamic systems theory – our focus is on how these theories consider the conceptual system; and 3) the enactivist linguistic approach to cognition. Then, based on introductory clarifications on these three theories, we suggest that the empirical evidence supports only a shallow perspective of the role of the body in cognition, by the linguistic enactivist standards, and we emphasize the importance of understanding the empirical reach of linguistic enactivism. Keywords: Language. Body. Cognition. Enactivism. Conceptual system. (shrink)

Dispositionalism about modality is the view that metaphysical modality is a matter of the dispositions possessed by actual objects. In a recent paper, David Yates has raised an important worry about the formal adequacy of dispositionalism. This paper responds to Yates’s worry by developing a reply that Yates discusses briefly but dismisses as ad hoc: an appeal to a ’plenitude of powers’ including such powers as the necessarily always manifested power for 2+2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} (...) \begin{document}$$2+2$$\end{document} to be 4. I argue that the reply is not ad hoc at all, by defending the metaphysics of dispositions that should underly it. I then argue, first, that a proper understanding of dispositions’ degrees provides us with an argument for such necessarily always manifested dispositions; second, that all the natural attempts to block that argument can be resisted without being ad hoc; and third, that pragmatic considerations explain our intuitive resistance to the ascription of necessarily always manifested dispositions. Dispositionalism can be formally adequate after all. (shrink)

This paper explores the prospects for dispositional accounts of abilities. According to so-called new dispositionalists, an agent has the ability to Φ iff they have a disposition to Φ when trying to Φ. We show that the new dispositionalism is beset by some problems that also beset its predecessor, the conditional analysis of abilities, and bring up some further problems. We then turn to a different approach, which links abilities not to motivational states but to the notion of success, and (...) consider ways of implementing that approach. Our results suggest that there are principled disanalogies between abilities and disposition which prevent any dispositional account of abilities from succeeding. (shrink)

Este artículo nos adentra en el estudio del problema del “jansenismo español” durante el siglo de Ilustración. En la primera parte se presenta el origen del jansenismo teológico, moral y disciplinar. Se indican sus representantes y sus obras. Más tarde se convierte en jansenismo político, también llamado jansenismo histórico. La influencia del pensamiento de los jansenistas franceses, holandeses e italianos sobre los jansenistas españoles es evidente y fehaciente. La historiografía sobre el particular es abundante. Se presentan las características más importantes (...) del jansenismo español, en relación con el despotismo ilustrado, el regalismo y el reformismo, además de un gran interés por la Biblia, el Derecho y la Historia.

Este artículo nos adentra en el estudio de la figura de san Martín de Tours, el apóstol de la Galia, cuya influencia se deja sentir en toda Europa, especialmente en España. Se trata del primer santo no mártir después de la paz de Constantino. Resultó ser soldado por fuerza, obispo por obligación, monje por gusto. Representa un nuevo modelo de santidad. De eremita evoluciona a la vida cenobítica, como padre de monjes; y como obispo es el defensor civitatis además del (...) gran evangelizador del mundo rural de la Galia. A su alrededor se generan otros santos. Por otra parte, Tours es la ciudad en que comienza la via turonensis del célebre Camino de Santiago. El Apóstol Santiago y Martín de Tours comparten culto y compiten en santidad como grandes taumaturgos. (shrink)

Our objective in this paper is twofold: first, we intend to address the tenability of the enactivist middle way between realism and idealism, as it is proposed in The Embodied Mind. We do so by taking the enactivist conception of bringing forth a world literally in three conceptual levels: enaction, niche construction and social construction. Based on this proposal, we claim that enactivism is compatible with the idea of an independent reality without committing to the claim that organisms have cognitive (...) access to a world composed of properties specified prior to any cognitive activity. Our second goal is to show that our literal interpretation of bringing forth a world not only sustains the legitimacy of the middle way, but it also allows us to revive the conception of evolution as natural drift—which is perhaps the least examined aspect of the original enactivist theory and is central to the understanding of cognition in an enactive way. Natural drift focuses on how structural couplings between organism and environment trigger viable pathways of maintenance and reproduction, instead of selecting the most adapted trait to a pregiven environment. Thus, although enactivists typically do not explore the consequences of their views regarding evolutionary dynamics, we show how natural drift provides a suitable starting point. (shrink)

Logical Holism and Wittgenstein’s ‘Practical Turn’. – Logical holism is the idea that each elementary proposition belongs to a system and is logically connected to other propositions of that system. In this paper I explore this idea and draw its connections to the nature of negative propositions and the ‘problem of recognition’ on the basis of Wittgenstein’s Nachlass. In the first section I argue that in January 1930 the idea leads Wittgenstein to a better understanding of how the negative feature (...) is expressed in propositions, thereby raising the problem of recognition to which he is not yet able to find a proper solution. In the second section I explore how the problem still persists during Wittgenstein’s ‘practical turn’. What he now calls the ‘problem of representation’ forces him to change again his conception of propositions. In the final section I argue that this change is mainly due to the modification of his conception of hypotheses which urges a solution to the problem of representation, though the problem remains unsolved in January 1930.

BackgroundOrgan transplantation represents the most effective and acceptable therapy for end-stage organ failure. However, its frequent practice often leads to a shortage of organs worldwide. To solve this dilemma, some countries, such as Portugal, have switched from an opt-in to an opt-out system, which has raised concerns about respect for individual autonomy. We aimed to evaluate whether young university students are aware of this opt-out system so that they can make informed, autonomous and conscious decisions, as well as to identify (...) the factors that determine a positive attitude toward post-mortem organ donation.MethodsAn observational, cross-sectional study was developed and a questionnaire was administered to first-year students from six faculties of the University of Porto.ResultsOf the 841 participants, 60% were unaware that Portugal had adopted an opt-out system. Among the informed individuals, their main sources of information included social media, internet, and family. Furthermore, only 48% of all participants agreed with the current opt-out system. Female sex (p = 0.049; OR 1.393), knowledge of the law (p < 0.001; OR 4.749) and family being the primary source of information (p < 0.001; OR 2.855) were independent factors associated with a positive attitude toward post-mortem organ donation law.ConclusionsThere is a significant lack of knowledge among young university students regarding the presumed post-mortem organ donation law and how it works. Female sex, having family as a primary source of information and being aware of the presumed post-mortem organ donation law are the strongest independent factors that determine a positive attitude toward the opt-out system.

In this paper, I explore Wittgenstein’s conception of a hypothesis as articulated in Chapters XII and XXII of ‘Philosophical Remarks’. First, I argue that in Chapter XII, Wittgenstein draws on his account of infinity to begin to challenge the view that all hypotheses can be proven by empirical evidence. I then argue that in Chapter XXII that Wittgenstein sharpens this conception of hypotheses claiming that no hypotheses can be verified. Finally, I suggest that Wittgenstein’s conception of a hypothesis relates to (...) his practical view of how language functions. (shrink)

It is common in the cognitive and computational sciences to regard virtual reality (VR) as composed of illusory experiences, given its immersive character. In this paper, we adopt an ecological-enactive perspective on cognition (Sect. 3) to evaluate the nature of VR and one’s engagement with it. Based on a post-cognitivist conception of illusion, we reject the commonly held assumption that virtual reality experiences (VREs) are illusory (Sect. 4). Our positive take on this issue is that VR devices, like other technological (...) devices, can be embodied during use, which is why they can be the source of experiences (Sect. 5). We then propose a new concept to interpret VREs, namely, _allusion_, which means that the subject acts _as if_ the virtual experiences are real (Sect. 6). This kind of engagement has a volitional aspect, which is evident in the onboarding of VR devices and which allows us to distinguish VREs from other experiences. We conclude that, even though we have experiences that afford certain interactions in VR, the strong continuity between cognitive and biological processes is not sustained therein. This characterizes a difference of kind—given the current state of technology—between VREs and fully fledged cognitive states, which nevertheless allows for constrained experimentation in cognitive science.

Phronesis is essential for good decision‐making and actions. This literature review shows how phronesis has been discussed and related to elements of the field of administration and organizations. A search in the database systems Scopus, EBSCO, Web of Science, and Scielo, based on eligibility criteria, resulted in 43 theoretical and 14 empirical works. The analysis of these studies showed the most significant empirical contributions, the most cited authors, methods, journals, and central themes addressed in studies on phronesis to understand ethics (...) in business. From a virtue ethics perspective, we discuss the major theoretical and empirical contributions, as well as the implications of a restricted understanding of phronesis when it is treated apart from other elements of the virtue ethics framework. We present a synthesis of the concepts of phronesis, based on dimensions of magnitude and amplitude of the conceptions, ranging from formal to substantive phronesis, and covering individual, organizational, or societal levels of analysis. We argue that a substantive conception of phronesis within virtue ethics may improve our understanding of ethics because it assumes the interdependence of phronesis and moral virtues, integral anthropology, and the common good. We present a future research agenda, considering the study's limitations and findings. (shrink)

In this imaginative and provocative book, Barbara Goodwin explores the question of how lottery systems can achieve egalitarian social justice in societies with seemingly ineradicable inequalities. She begins with the utopian fable of Aleatoria, a country not unlike our own in the not-too-distant-future, where most goods are distributed by lottery--even the right to have children. She then analyzes the philosophical arguments for and against lottery distribution and a comparison of "justice by lottery" with other contemporary theories of justice. Goodwin also (...) applies her theory to practical problems in the real world which could be--or have been--justly resolved by the use of lotteries, such as military drafts, jury duty, and immigration eligibility. She demonstrates that in many areas, including that of political power, a regular and random reallocation of goods would be a fairer and more democratic method than the distributive systems found in liberal democracies today.

L'oeuvre de Merleau-Ponty est tout entiere commandee par le souci de mettre rigoureusement en oeuvre le mot d'ordre husserlien de retour aux choses memes, ce qui exige, conformement au geste amorce par Husserl dans la Krisis, de reconnaitre l'oeuvre de l'idealisation -c'est-a-dire de l'objectivation- la meme ou elle se fait oublier, afin de la neutraliser. A l'instar de Bergson, pour qui la tache de la philosophie etait d'aller chercher l'experience au-dessus du tournant ou, s'inflechissant dans le sens de l'utilite, elle (...) devient proprement l'experience humaine, pour Merleau-Ponty, la tache de la pensee est de se situer a ce tournant ou l'experience s'accomplit et se voile a la fois dans des productions ou elle se fait proprement humaine, de definir un sens de l'Etre anterieur a la bifurcation du preobjectif et de l'oeuvre idealisante. Le but des recherches est de tenter de clarifier la nature exacte du tournant de l'experience ainsi que le projet phenomenologique merleau-pontien. (shrink)

Sexting has been defined as sending, receiving, or forwarding sexually explicit messages, images, or photos to others through digital platforms, and can assume more consensual or more abusive and violent forms. This study aims to explore the prevalence of abusive sexting in Portuguese adolescents and the psychological characteristics of sexting abusers in terms of emotional and behavioral problems, potential markers of psychopathy, childhood trauma and maltreatment, and different forms of aggression. A cross-sectional study was conducted with 4,281 participants, aged 12–20 (...) years, of whom 204 engaged in abusive sexting behaviors and 182 self-identified as being a non-consensual sexting victim. Abusive sexting was more common among boys and middle adolescents, and abusive sexting victims were more likely to be children of single-parent families. Engaging in abusive sexting and being a victim of abusive sexting were also related to behavioral and emotional problems, callousness, experiences of neglect and abuse in childhood, and various forms of aggression. Implications for future research and intervention are discussed. (shrink)

In this paper, I discuss whether the view that understanding is the ability to relate the use of an expression to a certain purpose leads to a theory of meaning as use. In particular, I investigate the view that a theory of meaning relies on the assumption that use is related to immanent purposes of language. I inquire whether it is possible to identify those purposes that seem essential for the use of language. Interpreting Wittgenstein, I argue that this idea (...) relies on a misunderstanding between purposes and effects. Single purposes are not to be conceived of as essential for the use of language. However, if we want to speak of an essential purpose of language, I argue, this purpose is to be conceived of as an end in itself. I draw the conclusion that the use of language is an end in itself rather than a means that fulfils essential purposes. (shrink)

Contemporary issues involving knowledge and science examined from a constructivist-pragmatist perspective often labeled "relativism." Individual chapters include a review of the difference between constructivist-pragmatist epistemology and "social constructivism;" an examination of recent writings by Bruno Latour; a critique of computational methods in literary studies; a skeptical look at current efforts to "integrate" the humanities and the natural sciences; and reflections on the social dynamics of belief in relation to denials of climate change and to hopes expressed by environmentalists.

An extended analysis and account of the psychological/social/cognitive dynamics of intellectual controversy. The immediate focus is the recurrent failure of intellectual engagement, in encounters having to do with with truth, knowledge, language, science, and/or objectivity, between, on the one hand, rationalist-realist-objectivist philosophers and/or those they have instructed and, on the other hand, constructivist-pragmatist ("postmodern") theorists and/or those persuaded by their critiques and/or alternative views. Individual chapters examine critiques and defenses of objectivist-rationalist views in law, politics, literary studies, ethics, communication theory, (...) and philosophy of science. Theorists whose views are discussed critically at some length include legal scholar Robin West and philosophers Jürgen Habermas, Karl-Otto Apel, and Philip Kitcher. (shrink)

Limbal stem cell deficiency is a general term for diseases which are characterised by the impairment of the (...) limbus, limbal stem cells and their ability to replenish the corneal epithelium through proliferation and differentiation. Consequently, sufferers experience chronic pain and progressive blindness.

This book considers the context of the colonial policies of Britain, Locke's contribution to them, and the importance of these ideas in his theory of property. It also reconsiders the debate about John Locke's influence in America. The book argues that Locke's theory of property must be understood in connection with the philosopher's political concerns, as part of his endeavour to justify the colonialist policies of Lord Shaftesbury's cabinet, with which he was personally associated. The author maintains that traditional scholarship (...) has failed to do justice to Locke by ignoring the implications of contemporary British imperial policy for the interpretation of his political thought.
