A tendência de algumas visões naturalistas de deduzir o sentido da ação humana da sua natureza biológica conduz a naturalizar a violência como fenômeno político inexorável. A violência naturalizada leva a sociedade para a dinâmica da inexorável violência, cuja única solução é a legitimação de uma violência total. Propomos, neste ensaio, a desconstrução crítica dos determinismos naturalistas por meio da análise da ação humana e da especificidade de sua potência que se manifesta como potência criadora (Cornelius Castoriadis) e potência do (...) não (Giorgio Agamben). A potência da ação humana transcende os determinismos da sua natureza biológica, embora por eles esteja condicionada. The tendency some naturalist visions have to deduce the meaning of human action from their biological nature, leads to a naturalization of violence as an inexorable political phenomenon. Naturalized violence leads the society towards the dynamics of inexorable violence, whose only solution is legitimazing total violence. In this article we propose the critical deconstruction of naturalistic determinism by means of the analysis of human action and the specificity of its power, which is manifested as creative power (Cornelius Castoriadis) and power of no (Giorgio Agamben). The power of human action transcends the biological determinisms of its biologic nature, although the power of human action is conditioned by them. (shrink)

This essay defends that mimesis is an inherently agonistic and paradoxical human practice. The divergent views on mimesis by Plato and Aristotle, as well as by Adorno and Benjamin, are the philosophical manifestation of an agonistic tension of human mimesis that is not resolved in the exclusive truth of one of the positions, but remains as a permanent possibility to create alternative paths in history.

This paper aims to present a critique of naturalistic theories of violence. The context of this critique concerns the naturalization of violence, which induces the assimilation power as a form of violence. Therefore, we resumed the theses of Hannah Arendt and Michel Foucault on power and violence. The goal is not to list the differences between these authors on the subject, which are explicit in the development of the test, but show their concordance regarding the critique of power as something (...) synonymous with violence.

Este ensayo presenta un análisis arqueo-genealógico de la mímēsis humana en dos momentos: en su arkhē pre-socrático y en la interpretación platónica de la misma. El mismo desarrolla la tesis de que la mímēsis es una facultad humana atravesada por la condición paradójica a partir de la cual es factible su instrumentalización alienante de las conciencias, pero también su uso creativo para producir diferencias de lo semejante y semejanzas de lo diferente. la condición paradójica impide el reduccionismo de la mímēsis (...) a una única perspectiva. Se concluye el ensayo con algunos desdoblamientos críticos del carácter paradójico de la mímēsis en nuestro presente. (shrink)

RESUMO O presente ensaio apresenta uma análise crítica das atuais democracias que se esvaziaram do poder deliberativo do demos para se tornarem, cada vez mais, democracias espetaculares. Inicialmente, seguindo os estudos de Foucault, analisam-se as implicações da governamentalidade sobre a democracia, principalmente a partir da emergência da opinião pública como técnica da razão de Estado. Posteriormente, relacionam-se os estudos de Foucault com as teses de Agamben a respeito da burocracia e a hierarquia, a fim de compreendermos como estas pesquisas desembocam (...) no conceito de democracias espetaculares defendido por Agamben. ABSTRACT This essay presents a critical analysis of the current democracies that have emptied themselves of the deliberative power of the demos to become, more and more, spectacular democracies. Initially, following Foucault's studies, we analyze the implications of governmentality on democracy, especially from the emergence of public opinion as a technique of reason of state. Later, Foucault's studies are related to Agamben's theses on bureaucracy and hierarchy, in order to understand how these researches lead to the concept of spectacular democracies defended by Agamben.

A sacralidade da vida humana tornou-se um problema filosófico com desdobramentos éticos e políticos. Este ensaio apresenta uma arqueologia da sacralidade a partir dos estudos de Walter Benjamin e Giorgio Agamben, estabelecendo uma comparação com o sentido da sacralidade nas polis antigas. A sacralidade aparece como figura simbólica marcada pelo paradoxo – ao mesmo tempo que protege a vida pelo direito sagrado, o direito a captura e a ameaça com a exceção. Porém, o paradoxo é insuperável, já que constitui o (...) modo de ser do humano. (shrink)

Este ensaio desenvolve um estudo, a partir da obra de G. Agamben, sobre a arqueologia do ofício e as implicações ético-políticas do modo de subjetivação do funcionário. O funcionário age a partir do dever de oficio, separando, nessa ação, a responsabilidade pessoal da eficiência da ação. Ao agir como funcionário não atua em nome próprio, mas age em nome de outro, para o qual se transfere toda responsabilidade ética da ação funcional. Eichmann apresenta-se como o modelo de funcionário que cumpriu (...) o dever de sua função, independentemente de suas convicções pessoais a respeito da catástrofe humana que provocou. (shrink)

A noção de pessoa, para Simone Weil, passa por uma certa desconstrução e releitura que a filósofa realiza a partir da categoria do impessoal. Abordaremos inicialmente os conceitos de direito e obrigação, refletindo sobre as necessidades da alma pensadas por Weil, em que a obrigação abre o ser humano para o impessoal da pessoa, que por sua vez é conexo com o sentido do eterno e do sagrado. Neste escrito pretende-se resgatar alguns traços desta reflexão e destacar a relação entre (...) o impessoal com o eterno e o sagrado, enquanto constitutivos do ser humano, estudando como a partir do impessoal emerge uma nova percepção da relação ética.

En la presente investigación proponemos profundizar en el concepto de ecocidio y sus implicaciones ético-políticas, relacionándolo con los conceptos de soberanía y estado de excepción de Giorgio Agamben. El concepto de excepción, en la tradición jurídica y filosófica, está referido al ámbito de la vida de las personas y no al daño producido a la vida en la naturaleza. Sin embargo, partiendo del presupuesto de que hay una interdependencia de la vida humana con la vida de la naturaleza, se analizan (...) los desdoblamientos ético-políticos a los que esa interdependencia nos conduce, teniendo como eje el concepto de ecocidio. Para este análisis proponemos recorrer los vínculos entre ecocidio y estado de excepción como dos prácticas asimiladas que, para destruir la vida, la reducen a una insignificancia ética a través de un vacío jurídico.

Na modernidade, ciência e ética raramente conviveram em harmonia. Sua relação conflitante sempre demarca sobre os tipos de verdade de ambos discursos. A construção de qualquer consenso entre os discursos científico e ético se mantém sobre uma base instável de mútua desconfiança. Essa instabilidade implica, comumente, um confronto permanente entre as verdades e os critérios de ambos discursos. O conflito entre ciência e ética se dá, essencialmente, no campo da teoria da linguagem, ou seja, na análise do discurso. As pretensões (...) de verdade e os efeitos de poder das verdades científicas e éticas, são correlativos ao reconhecimento da verdade de suas proposições e da validade do seu discurso. Para contribuir com alguns esclarecimentos neste debate entre ciência e ética, deveremos, pois, nos introduzir em alguns pontos da teoria da linguagem, ou seja, na historicidade e na hermenêutica.

A partir da segunda metade do século XX, as políticas econômicas disseminaram um conjunto de dispositivos sutis, no sentido de seu exercício, ao mesmo tempo em que mais plurais, em relação à sua extensão. Um dos principais deslocamentos epistemológicos produzidos pelo discurso neoliberal diz respeito à inserção da subjetividade humana como elemento central da racionalidade econômica. A inclusão da subjetividade na lógica dos cálculos econômicos possibilitou construir a figura do homo oeconomicus como referente antropológico do novo discurso neoliberal. Um dos (...) principais autores nessa jornada é Ludwig von Mises. A teoria misiana é profundamente filosófica: dela é possível coletar toda a estrutura da teoria neoliberal e de seu contraste bifocal entre a ação econômica do mercado e a teoria política do Estado, e nela o homo oeconomicus ocupa um lugar central. A genealogia de Michel Foucault sobre o escopo da governamentalidade neoliberal trouxe um olhar crítico diferente sobre os princípios constitutivos deste discurso. A par da teoria de Mises, a leitura de Foucault nos é precisa, na medida em que nos permite contrastar a razão de governo, constituída ao longo dos modelos de pensamento, com aquela ótica empresarial do homo oeconomicus como um suposto sujeito soberano. O intuito deste ensaio é provocar um cruzamento crítico entre o pensamento de Mises e de Foucault, concentrado principalmente no estudo das contradições que surgem no seio do discurso neoliberal da figura do homo oeconomicus como sujeito soberano, com as práticas de governamentalização desse mesmo homo oeconomicus. O ensaio é constituído de três momentos: primeiramente, nosso objetivo é compreender a teoria do mercado de von Mises, com o intuito de alinhavar alguns conceitos importantes, em especial o conceito de soberania do homo oeconomicus; em seguida, temos como pretensão analisar a teoria de Foucault sobre a governamentalidade neoliberal, acenando em direção ao modo pelo qual a teoria de Mises projeta-se como uma razão econômica de governo; em um terceiro ponto, desenvolvemos algumas implicações derivadas dos cruzamentos das teses sobre a soberania do homo oeconomicus, de Mises, com as análises sobre a governamentalidade desse homo oeconomicus desenvolvidas pelos estudos de Foucault.

A ética é uma prática que coimplica subjetividade e da alteridade. Nas atuais sociedades de controle se procura fabricar subjetividades destemperadas numa ética do descuido de si. As éticas do cuidado de si visavam ajudar a constituir sujeitos livres pela prática ética da virtude. Os novos dispositivos de controle atualizaram o poder da ética como prática em que o sujeito pode dirimir seu estilo de vida entre a sujeição ou a liberdade. As éticas do cuidado de si desconsideraram a importância (...) da alteridade para pensar a prática ética. Embora existam divergências importantes entre ambas perspectivas éticas, elas coincidem em afirmar a ética como uma prática que incide na constituição dos sujeitos, uma prática de liberdade de si (Foucault) e uma prática de libertação do outro como justiça (Levinas). PALAVRAS-CHAVE – Alteridade. Cuidado de si. Modos de subjetivação. Liberdade. Desejo. (shrink)

Professor de Filosofia da Universidade do Vale Rio dos Sinos (Unisinos), no Rio Grande do Sul, Castor M.M. Bartolomé Ruiz é um estudioso dos mecanismos do poder e da chamada “biopolítica”, dialogando sobretudo com as obras dos filósofos Giorgio Agamben e Michel Foucault.

The aims of this research were twofold: first, to compare the levels of organisational harmony between family and non-family firms and, second, to study the influence of organisational harmony on family firms’ performance (profitability, longevity and group cohesion). Starting from a definition of organisational harmony as a value and considering the importance of the management of organisational values, we use the main topics indicated by the general literature (organisational climate, trust and participation) to analyse organisational harmony, as well as three (...) other topics for performance (profitability, survival and group cohesion). Results indicate that family firms have higher levels of these three qualities than non-family firms, and that the levels of trust, participation and organisational climate have a positive and significant influence on the performance of family firms. These results can be understood as a consequence of the influence of family social capital on organisational social capital and so on the performance of family businesses. From the perspective of institutionalism, the higher levels of harmony existing in family businesses are a reflection of the pressures that the owning family as an institution exercises on the organisational social capital in its companies.

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree in (...) Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)

Global environmental problems, such as global warming, pollution, or deforestation, are critical issues that require a rapid and common response. In this context, companies play a decisive role in achieving environmental objectives through the ecological knowledge they can store and manage. In this context, the present research focuses its interest on analyzing how the set of green intangibles possessed by organizations, i.e., Green Intellectual Capital, affects their Green Performance. Specifically, the study shows how GP is influenced by GIC through the (...) mediating role of the Green Innovation variable. Therefore, the research questions to be answered by this study are as follows: Does GIC influence environmental performance? Does GI mediate the GIC-GP relationship? What actions can companies take to improve their GP? There are several reasons that have led us to carry out this research. First, there is little empirical evidence of the relationships proposed in this study. Second, to the best of our knowledge, there is no previous research that has contextualized the relationships raised in the wine industry, thus representing an advance in the comprehension of the constructs studied. Third, GIC represents an incipient field of study that needs to be developed and established within the literature linked to Intellectual Capital. In order to achieve the proposed objectives, data from a survey of 202 wineries in Spain were used and a quantitative approach was followed using Structural Equation Modeling. The results of the research indicate that there is a positive and significant relationship between GIC and GP. In addition, GI partially mediates the relationship between these two variables, playing a key role in the environmental management of wineries. The theoretical and practical contributions of the study improve the understanding of the relationships raised, being a pioneering study due to its contextualization in the wine industry, as well as providing a series of guidelines for both environmental managers and winemakers to improve their GP.

Objectives—To assess the relationship between the approval of trials by a research ethics committee and the fact that informed consent from participants was obtained, with the quality of study design and methods.Design—Systematic review using a standardised checklist.Main measures—Methodological and ethical issues of all trials published between 1993 and 1995 in the New England Journal of Medicine, the Lancet, the Journal of the American Medical Association and the British Medical Journal were studied. In addition, clinical trials conducted in Spain and published (...) by at least one Spanish author during the same period in any other journal were also included.Results—We studied the published articles of 767 trials and found the following indicators of lower methodological quality to be independent predictors for failure to disclose REC approval or ICP: absence of concealment of allocation, lack of justification for unblinded trials, not using a treatment for the patients in the control group, absent information on statistical methods, not including sample size estimation, not establishing the rules to stop the trial, and omitting the presentation of a baseline comparison of groupsConclusion—Trials of higher methodological and scientific quality were more likely to provide information about their ethical aspects.

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two (...) factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.

In a well-known article, Hodnett pointed out that Virgil emphasizes the peacefulness and quiet of the sea, its immensity and limitlessness, in contrast to the view articulated by the Roman poets of the Republic, which presents the sea as deceptive and fearsome. Among the many terms used in theAeneidto denote the sea,aequorstands out precisely because it is the term most frequently used by Virgil in place of the wordmare.

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D (...) ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions. (shrink)

The study investigated the influence of resilience and dispositional optimism on, first, emotional distress and, second, the intention to self-isolate, experienced by people with a lower and higher illness risk, during the lockdown imposed in Spain during the first COVID-19 wave. These effects were investigated against the background of the Health Belief Model. A convenience sample of N = 325 participants completed an online survey including an ad-hoc questionnaire measuring the HBM core factors: Perceived health threat, and perceived quarantine benefits (...) and costs. Self-efficacy and perceived social pressure were also measured. Based on reviews regarding pandemic outbreaks, quarantine benefits were conceptualized as the perceived effectiveness and solidary contribution of self-isolating in line with the quarantine protocols. Quarantine “psychosocial” costs were conceptualized as a composite of perceived boredom, loneliness, and economic concerns. Findings revealed an asymmetrical pattern of results so that people at higher risk were more distressed by the perceived severity of getting infected whereas people at lower risk were more distressed by the psychosocial costs. Moreover, resilience and optimism were more “protective” against distress within the lower and higher risk groups, respectively. In addition, quarantine benefits and self-efficacy promoted the intention to self-isolate within both groups. However, optimism hindered such intention. This finding is discussed in the light of links between dispositional optimism and optimistic bias; the underestimation of experiencing negative events, which can relax the perceived health risk. Based on these findings, communication campaigns should prioritize information about the effectiveness of the implemented preventive behaviors rather than the costs of not implementing them, and be cautionary in encouraging excessive optimism.

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

The purpose of this study is to investigate the role of school principal trustworthiness components (i.e., ability, integrity, benevolence) in helping shape teacher trust and affective commitment within schools. Using data from 1,026 teachers in Spain and structural equation modeling (via EQS 6.3), this study establishes how a principal’s integrity and benevolence are key in determining, both directly and indirectly (via trust in the principal), teachers’ affective commitment to their school. It also reveals that the perceived ability of a principal (...) is not effective in generating trust or affective commitment to the school in teachers. As a contribution to the literature, these findings reveal that the ethical trustworthiness (benevolence, integrity) of principals is key in engendering trust and affective commitment to schools. Thus, to shape work environments that are high in trust and commitment, principals should focus on behaving in ways that make their integrity and benevolence manifest to their teachers. (shrink)

Multi-Task Learning tries to improve the learning process of different tasks by solving them simultaneously. A popular Multi-Task Learning formulation for SVM is to combine common and task-specific parts. Other approaches rely on using a Graph Laplacian regularizer. Here we propose a combination of these two approaches that can be applied to L1, L2 and LS-SVMs. We also propose an algorithm to iteratively learn the graph adjacency matrix used in the Laplacian regularization. We test our proposal with synthetic and real (...) problems, both in regression and classification settings. When the task structure is present, we show that our model is able to detect it, which leads to better results, and we also show it to be competitive even when this structure is not present.

Despite the emphasis placed by most curricula in the development of social and emotional competencies in education, there seems to be a general lack of knowledge of methods that integrate strategies for assessing these competencies into existing educational practices. Previous research has shown that the development of social and emotional competencies in children has multiple benefits, as they seem to contribute to better physical and mental health, an increase in academic motivation, and the well-being and healthy social progress of children. (...) This study aims at assessing the possible changes in children’s self-esteem, socio-emotional competencies, and school-related variables after participating in the Learning to Be project (L2B) project.Methods:This quasi-experimental study included an intervention group (L2B) and a control group. The participants were 221 students in primary education (55.2% girls) between the ages of eight and 11 (M= 9.31; SD = 0.89). The L2B intervention program took place over a period of 5 months. The assessment was carried out twice, before and after the intervention through three main evaluation instruments: the Rosenberg’s Self-Esteem questionnaire, the Socio-Emotional competence questionnaire (SEQ), and self-report scales for measuring school difficulties, school engagement, opinions about school, and school absence. Ten schools from different Spanish provinces participated.Results:The results indicate that those participants in the experimental group show higher self-esteem, better responsible decisions, and higher self-awareness than those in the control group. There were no other statistical differences between groups.Conclusions:The results of this work suggest that the implementation of the L2B program did not improve social and emotional competencies in primary school students. Further research related to how include formative assessment in SEL programs is needed. (shrink)

Introduction: The use of human samples in genomic research has increased ethical debate about informed consent (IC) requirements and the information that subjects should receive regarding the results of the research. However, there are no quantitative data regarding researchers’ attitudes about these issues. Methods: We present the results of a survey of 104 US and 100 Spanish researchers who had published genomic epidemiology studies in 61 journals during 2006. Results: Researchers preferred a broader IC than the IC they had actually (...) obtained in their published papers. US authors were more likely than their Spanish colleagues to support obtaining a broad IC, covering either any future research project or any projects related to a group of diseases (67.6% vs 43%; adjusted OR = 4.84, 95% CI, 2.32 to 10.12). A slight majority of researchers (55.8%) supported informing participants about individual genomic results only if the reliability and clinical validity of the information had been established. Men were more likely than women to believe that patients should be informed of research results even if these conditions were not met (adjusted OR = 2.89, 95% CI = 1.46 to 5.72). Conclusions: This study provides evidence of a wide range of views among scientists regarding some controversial ethical issues related to genomic research, suggesting the need for more study, debate and education. In the interim, journals might consider including the investigators’ policies regarding these ethical issues in the papers they publish in the field of genomic epidemiology. (shrink)

The fast–slow paradigm of life history focuses on how individuals grow, mate, and reproduce at different paces. This paradigm can contribute substantially to the field of personality and individual differences provided that it is more strictly based on evolutionary biology than it has been so far. Our study tested the existence of a fast–slow continuum underlying indicators of reproductive effort—offspring output, age at first reproduction, number and stability of sexual partners—in 1,043 outpatients with healthy to severely disordered personalities. Two axes (...) emerged reflecting a double-track pathway to fast strategy, based on restricted and unrestricted sociosexual strategies. When rotated, the fast–slow and sociosexuality axes turned out to be independent. Contrary to expectations, neither somatic effort—investment in status, material resources, social capital, and maintenance/survival—was aligned with reproductive effort, nor a clear tradeoff between current and future reproduction was evident. Finally, we examined the association of LH axes with seven high-order personality pathology traits: negative emotionality, impulsivity, antagonism, persistence-compulsivity, subordination, and psychoticism. Persistent and disinhibited subjects appeared as fast-restricted and fast-unrestricted strategists, respectively, whereas asocial subjects were slow strategists. Associations of LH traits with each other and with personality are far more complex than usually assumed in evolutionary psychology. (shrink)

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)
