I propose a theory aimed at advancing scholarly research in social entrepreneurship. By highlighting the key trade-off between value creation and value capture and explaining when situations of simultaneous market and government failure may arise, I suggest that social entrepreneurship is the pursuit of sustainable solutions to neglected problems with positive externalities. I further discuss the situations in which problems with externalities are likely to be neglected and derive the central goal and logic of action of social entrepreneurs, in contrast (...) to commercial entrepreneurs. Overall, this article provides a conceptual framework that allows understanding the growing phenomena of social entrepreneurship and its role in the functioning of modern society. (shrink)

This article argues against Catton and Dunlap’s claims that the natural environment has been ignored or downplayed in American sociology before the emergence of environmental sociology in the 1970s. By reviewing a collection of 86 sociology textbooks between 1894 and 1980, the article provides quantitative evidence regarding the scope and types of references to the natural environment in mainstream sociology. The bulk of the article is based on an interpretive-historical analysis of the different representations of the environment in the textbook (...) literature. This analysis is carried out from the perspective of the sociology of knowledge, whereby sociological ideas about nature are interpreted in terms of their intellectual milieu and social context. The main finding is that the ‘natural environment’ has been interpreted in different ways and has been put to a variety of epistemological and ideological uses — particularly positivism and functionalism — throughout the history of the discipline.

The Polish football fans community has been recently in the scope of several academic studies, concerning – mostly – numerous deviations presented by its members. What has been left underestimated is the formal and practical capacity the football fans community to influence both the public opinion, as well as local and national governments. Albeit controversial, the “fanatic” football fans characteristics are inherently inscribed in the personal identities of the group’s members; they exceed simple “friend-foe” distinctions, rather consisting of a complex (...) set of social and political views, rooted in communitarian and neo-conservative philosophies. In my lecture, I wish to discuss how the football fans community reacts to both theoretical projects of the post-modern society and its practical implementations. By stressing out the declared criticism of the changes taking place in modern society, I wish to evoke the neglected dimension of the football fans society – that of a conservative educator and political actor.

This commentary explores how emotion fits in the dual-systems model of temporal cognition proposed by Hoerl & McCormack. The updating system would be affected by emotion via the attentional/arousal effect according to the attentional gate model. The reasoning system would be disrupted by emotion, especially for traumatic events. Time discrepancies described in the dual-systems model are also explained.

The practical importance of auction theory is widely recognized. Indeed, economists have been recognized for their contribution to the design of several auction-like mechanisms, such as the U. S. Federal Communications Commission spectrum auctions, the 3G auctions in Europe and beyond, and the auction markets for electricity markets around the world. This book provides a step-by-step, self-contained treatment of the theory of auctions. The aim is to provide an introductory textbook that will allow students and readers with a calculus background (...) to work through all the basic results. Coverage includes: the basic independent-private-model; the effects of introducing correlation in valuations on equilibrium behaviour and the seller's expected revenue; mechanism design; and the theory of multi-object auctions. The paperback edition of the text includes a new chapter which acts as a guide to current developments in auction theory. (shrink)

BackgroundThe rating of perceived exertion scales with respiratory and muscular illustrations are recognized as simple and practical methods to understand individual psychometric characteristics in breathing and muscle exertion during exercise. However, the implementation of respiratory and muscular RPE to quantify training load in futsal training camps has not been examined. This study investigates respiratory and muscular RPE relationships during domestic training camps and overseas training camps in an under 20 futsal national team.MethodsData collected from eleven field players were used for (...) comparison in this study. All players reported Borg CR10 RPE and 7-scales respiratory RPE and muscular RPE after training sessions and matches. Additionally, total distance covered and training impulse were used to quantify external and internal loads via the Polar Team Pro system. Paired-sample t-tests were used to compare the RPECR10, RPErespiration, RPEmuscle, TD, and TRIMP between DTC and OTC. Furthermore, linear regression was performed to determine the relationships among all RPE scales, TD, and TRIMP.ResultsThe RPECR10, TD, and TRIMP showed significant difference between DTC and OTC. Furthermore, linear regression analyses showed significant correlation between RPErespiration and RPEmuscle, RPECR10 and RPErespiration, and RPECR10 and RPEmuscle.ConclusionPictorial RPErespiration or RPEmuscle can be used as an alternative to quantify perceived measures of internal loads during DTC and OTC in futsal players. Interpretation of perceived measures of training load and cardiac-related responses in association with external training loads during short-term training camps would be useful in further understanding the demands of futsal players’ experience in these circumstances.

Este artigo tem como objetivo principal apresentar uma reconstruçáo lógico-conceitual e avaliaçáo de três argumentos de Skinner para a tese de que os termos psicológicos comuns sáo, em geral, inadmissíveis em análise do comportamento (a tese da inadmissibilidade). Começamos fazendo uma revisáo da abordagem de tais termos sustentada por Skinner, particularmente sua abordagem das categoriais de termos psicológicos disposicionais. Muito dela é aqui aceito, mas adotamos, como hipótese de trabalho, um desacordo com a premissa de Skinner de que eles sejam (...) irremediavelmente mentalistas. Nossa análise mostra que, se esta hipótese estiver correta, entáo os argumentos analisados náo resultam ser inteiramente plausíveis; e, embora a opçáo do autor seja plenamente aceitável, também o é uma (em princípio) opçáo alternativa, que explore os valores heurísticos de tais termos (sem incorporá-los ao vocabulário de base) para a descoberta de padrões comportamentais e seus contextos, em ambientes abertos de pesquisa. Um objetivo colateral deste artigo é mostrar o equívoco de duas suposições muitas vezes assumidas em filosofia da mente sobre o behaviorismo radical: a de que ele náo tem uma abordagem relevante sobre o funcionamento dos termos em questáo e a de que sua tese da inadmissibilidade se baseia em premissas verificacionistas.

During the early Cambrian period metazoan life forms diverged at an accelerated rate to occupy multiple ecological niches on earth. A variety of explanations have been proposed to address this major evolutionary phenomenon termed the “Cambrian explosion.” While most hypotheses address environmental, developmental, and ecological factors that facilitated evolutionary innovations, the biological basis for accelerated emergence of species diversity in the Cambrian period remains largely conjectural. Herein, we posit that morphogenesis by self‐organization enables the uncoupling of genomic mutational landscape from (...) phenotypic diversification. Evidence is provided for a two‐tiered interpretation of genomic changes in metazoan animals wherein mutations not only impact upon function of individual cells, but also alter the self‐organization outcome during developmental morphogenesis. We provide evidence that the morphological impacts of mutations on self‐organization could remain repressed if associated with an unmet negative energetic cost. We posit that accelerated morphological diversification in transition to the Cambrian period has occurred by emergence of dormant (i.e., reserved) morphological novelties whose molecular underpinnings were seeded in the Precambrian period.

Leadership plays an essential part in creating competitive advantage and well-being among employees. One way in which formal leaders can deal with the variety of responsibilities that comes with their role is to share their responsibilities with team members (i.e., shared leadership). Although there is abundant literature on how high-quality peer leadership benefits team effectiveness (TE) and well-being, there is only limited evidence about the underpinning mechanisms of these relationships and how the formal leader can support this process. To address (...) this lacuna, we conducted an online survey study with 146 employees from various organizations. The results suggest that an empowering leadership style of the formal leader is associated with higher perceived peer leadership quality (PLQ) on four different leadership roles (i.e., task, motivational, social, and external leader). In addition, formal leaders who empower their team members are also perceived as better leaders themselves. Moreover, the improved PLQ was in turn positively related to TE and work satisfaction, while being negatively related to burnout. In line with the social identity approach, we found that team identification mediated these relationships. Thus, high-quality peer leaders succeeded in creating a shared sense of “us” in the team, and this team identification in turn generated all the positive outcomes. To conclude, by sharing their lead and empowering the peer leaders in their team, formal leaders are key drivers of the team’s effectiveness, while also enhancing team members’ health and well-being.

In this paper we suggest a model of sequential auctions with endogenous participation where each bidder conjectures about the number of participants at each round. Then, after learning his value, each bidder decides whether or not to participate in the auction. In the calculation of his expected value, each bidder uses his conjectures about the number of participants for each possible subgroup. In equilibrium, the conjectured probability is compatible with the probability of staying in the auction. In our model, players (...) face participation costs, bidders may buy as many objects as they wish and they are allowed to drop out at any round. Bidders can drop out at any time, but they cannot come back to the auction. In particular we can determine the number of participants and expected prices in equilibrium. We show that for any bidding strategy, there exists such a probability of staying in the auction. For the case of stochastically independent objects, we show that in equilibrium every bidder who decides to continue submits a bid that is equal to his value at each round. When objects are stochastically identical, we are able to show that expected prices are decreasing. (shrink)

The relationship of humans to other primates – both in terms of abilities and evolution - has been an age-old topic of dispute in science. In this paper the claim is made that the different views of authors are based not so much on differences in empirical evidence, but on the ontological stances of the authors and the underlying ground narratives that they use. For comparing and reconciling the views presented by the representatives of, inter alia, cognitive ethology, comparative psychology, (...) and zoosemiotics, an overarching approach of multi-constructivism is introduced. The paper proposes an analytic model that distinguishes four logical possibilities in representing anthropological difference: Gradualism, Transformativism, Unitarism, and Pluralism. Using this typology, the views of C. Darwin, F. de Waal, M. Tomasello, and T. A. Sebeok regarding the similarities and differences between human and animal capacities for cognition, culture and communication are analyzed. The results indicate systematic differences in the selected narratives by these authors that can be related to the types of underlying ontologies. (shrink)

Twórczość może być formą rozwiązania konfliktu i przemiany energii seksualnej, formą obrony psychologicznej i odbudowy swojego,,ja”, czynnością harmonizowania swojego,,cienia” ze sobą i wyrazem archetypu, sposobem przekroczenia swojego typu psychologicznego i rozwoju osobowości, a także mistycznym połączeniem przedmiotu i podmiotu oraz egzystencjalną psychosyntezą.

In 2009, we celebrated the bicentennial of the birth of Charles Darwin and the sesquicentennial of the publication of his book The Origin of Species. This seems to be a good opportunity to evaluate the importance of Darwin’s work for the social sciences, mainly for philosophical anthropology. The aim of this paper is to discuss the traditional anthropocentric conceptions of man, which consider our biological species to be exceptional – qualitatively higher than other living organisms. Over the course of the (...) 20th century, philosophers have argued for the claim in a number of ways: man is supposed to be the only animal capable of laughter, love, thought or language. It has also been claimed that only members of Homo sapiens have free will, morality or religion. The paper refutes these arguments on the basis of contemporary studies by M. Davila Ross, H. Fischer, K. Arnold, K. Zuberbühler, G. Konopka, B. Libet, F. De Waal, M. Bekoff, P. Boyer, B. Hood, G. Paul and others. The author argues that the only differences between man and other animals are quantitative, and therefore the nature of humans should be studied using the methods of naturalized philosophy, with respect to the natural sciences.

Traditionally, the so-called ‘redintegration experiment’ is at the center of the comments on the supposed Boyle/Spinoza correspondence. A. Clericuzio argued (refuting the interpretation by R.A. & M.B. Hall) in his influential publications that, in De nitro, Boyle accounted for the ‘redintegration’ of saltpeter on the grounds of the chemical properties of corpuscles and did not make any attempt to deduce them from the mechanical principles. By contrast, this paper claims that with his De nitro Boyle wanted to illustrate and promote (...) precisely his new Corpuscular or Mechanical Philosophy, and that he did significant attempts to explain the phenomena in terms of mechanical qualities. Boyle had borrowed the ‘redintegration experiment’ from R. Glauber and used it as a tool to prove that his philosophy was the right alternative for the Peripatetic and Paracelsian theory of qualities of bodies. Consequently, Clericuzio’s characterization of the Boyle/Spinoza controversy as a discussion between a strict mechanical philosopher and a chemist is problematic and should be revised. (shrink)

Tato studie je inspirována knížkou Petra Urbana Jak rozumíme druhým? Studie o sociálním rozumění a sdílení světa nejen u člověka a věnuje se současným diskuzím o povaze sociálního rozumění, zejména v případě nelinguálních tvorů. Nejvýraznější pozice zastává na jedné straně skupina srovnávacích psychologů kolem M. Tomasella, která vychází z filosofů kolektivní intencionality, na straně druhé D. Leavens a K. Bardová, kteří mají blízko k interaktivistické interpretaci problému sociálního rozumění. Bude ukázáno, že rozdíly ve výsledcích empirických výzkumů mají základ v ontologických (...) závazcích jednotlivých výzkumných programů, přičemž důležitou roli hraje vymezení se vůči problému antropologické diference. Studie se táže, je-li možné prostředky filosofi e vědy mezi soupeřícími teoriemi rozhodnout. Na závěr je uvedena možnost biosémiotické reinterpretace mimo-lidského sociálního rozumění na pozadí teorie umweltu. (shrink)

Článek představuje teorii původu lidské morálky od Franse de Waala a zhodnocuje přínos filozofických komentářů od Christine M. Korsgaardové a Mary Midgleyové z hlediska oboru evoluční etiky. Základní struktura de Waalova přístupu je v souladu se sentimentalistickou teorií morálky, která určuje soucítění jako bazální morální cit. V interpretaci vlivné neodarwinistické genocentrické školy dále hraje zásadní roli altruismus. Stoupenci tohoto směru (R. Dawkins, G. C. Williams) nicméně obhajují rozdělení krutého světa přírody a etického světa lidské kultury; distinkce byla Fransem de Waalem (...) nazvána „teorií pozlátka“, neboť vyvolává obraz tenké vrstvy morálky nanesené na sobecké jádro lidské biologické přirozenosti. C. M. Korsgaardová využívá kantovskou etiku, aby ukázala, že zvířata nemohou být počítána za morální, neboť postrádají schopnost normativní autonomie. M. Midgleyová oponuje jak neodarwinistickému, tak kantovskému rozvrhu etiky a ukazuje, že soucítění patří k přirozenosti společensky žijících druhů a že reflektivní uvažování se vztahuje pouze k nejvyššímu patru evoluce morálky. Pozice M. Midgleyové je pro evoluční zkoumání morálky přínosnější než postup C. M. Korsgaardové. This article introduces Frans de Waal’s theory of the origins of human morality and evaluates the merits of the philosophical commentaries of Christine M. Korsgaard and Mary Midgley, and their application to the discipline of evolutionary ethics. The fundamental structure of de Wall’s approach is congruent with the sentimentalist theory of morality which determines sympathy as the most vital moral sentiment. A crucial role is also assigned to altruism in the view of morality in the influential genocentric neo-Darwinian school. However, proponents of this school (R. Dawkins, G. C. Williams) advocate the separation of the cruel world of nature and the ethical world of humane culture; this is dubbed “Veneer Theory” by F. de Waal, since it invokes an image of a thin layer of morality applied to a selfish core of biological human nature. C. M. Korsgaard applies Kantian ethics to argue that animals cannot count as moral because they are not capable of normative self-government. M. Midgley opposes both neo-Darwinism and the Kantian tradition in ethics in arguing that sympathy is a part of any social species’ nature, and that reflective reasoning refers only to the highest peak of moral evolution. It is argued that the position of M. Midgley is ultimately a more fruitful approach to the evolutionary examination of ethics than that proposed by C. M. Korsgaard. (shrink)

U ovom se radu pokušava pokazati da postoji određena vrsta relativizma koja je spojiva sa skepticizmom Seksta Empirika. Tvrdi se da se u PH I.217–219 Protagora ne shvaća kao aletički ili epistemički relativist, nego kao relativist u minimalnom smislu riječi, te da takvo stajalište nije protivno pironizmu kako ga Sekst karakterizira u PH I. Potom se pokazuje da nam prihvaćanje toga aspekta pironizma može pomoći da objasnimo neke inače problematične relativističke zaključke što ih nalazimo u Sekstovim spisima, naročito u M (...) XI.In this paper an attempt is made to show that there is a kind of relativism that can be seen as compatible with Sextus Empiricus’ scepticism. It is argued that in PH I.217–219, Protagoras is not treated as alethic or epistemic relativist, but as a relativist in a minimal sense of the word, and that such a position is not at odds with Sextus’ characterisation of Pyrrhonism in PH I. It is then shown that recognising this aspect of Pyrrhonism can help us explain the otherwise problematic relativistic conclusions in Sextus’ works, esp. in M XI. (shrink)

W filozofii czasu Ingardena szczególną rolę odgrywa charakterystyka ontologiczna teraźniejszości. Należy do niej m.in. szczelinowość. Okazuje się, że pojęcie to można powiązać z koncepcją tzw. teraźniejszości pozornej (specious present). Opierając się ponadto na pewnych rozważaniach S. Lema oraz B. Ogrodnika wiążę różne wartości szczelinowości (trwania kwantu teraźniejszości), ze złożonością formalną budowy przedmiotów. Uogólnienie tych wyników umożliwia dopełnienie rozważań Ingardena nad szczelinowością – sformułowanie zarysu ontologicznej teorii względności trwania teraźniejszości.

Physical Education (PE) aims to convey the joy of exercise and by this educate students to lifelong physical activeness. Student motivation in PE decreases during the school career. This study therefore comprehensively analyzes student characteristics determining motivation in PE:General Personality Traits, Physical Self-Concept, Achievement Motive, Motives to be physically active, andSports Interest. This contribution aims to describe students' prerequisites in the PE context by using an aggregated assessment of the abovementioned general plus sport specific characteristics and to detect gender, class, (...) and school type differences. In total, 1,740 German secondary school students (58.1% female, M = 14.39 years) participate in a cross-sectional questionnaire survey. Descriptive analyses and between subjects MANOVAs followed by univariate ANOVAs with pairwise multiple comparison tests are applied. Gender explains the largest proportion of variance across all characteristics. Regarding individual dimensions, genders differed on 12, grades on two and school types on 11 out of 19 dimensions. PE teachers must adapt teaching to different gender dispositions. In general, group differences ascribe special meaning to student perception and teaching behavior. Findings are discussed in terms of their contribution to the research area and their implementation in teaching practice as well as in PE teacher education or professional training, e.g., aligned teaching methods, arranged learning atmospheres, or adjusted content design of PE lessons.
