Discussion about project management, in both the academic literature and industry, is predominantly based on theories of control, many of which have been developed since the 1950s. However, issues arise when these ideas are applied unilaterally to all types of projects and in all contexts. In complex environments, management problems arise from assuming that results, predicted at the start of a project, can be sufficiently described and delivered as planned. Thus, once a project reaches a critical size, a calendar, and (...) a certain level of ambiguity and interconnection, the analysis centered on control does not function adequately. Projects that involve complex situations can be described as adaptive complex systems, consistent in multiple interdependent dynamic components, multiple feedback processes, nonlinear relations, and management of hard data and soft data. In this study, through a complex network, the dynamic structure of a project and its trajectories are simulated using inference processes. Finally, some numerical simulations are described, leading to a decision making tool that identifies critical processes, thereby obtaining better performance outcomes of projects. (shrink)

Uma das principais preocupações de Ludwig Wittgenstein, presente já desde as suas primeiras observações, é a autonomia do pensamento próprio. Nosso objetivo neste texto é indicar alguns aspectos metodológicos do diagnóstico e da crítica que o filósofo vienense opera em relação à tradição filosófica ocidental com vistas a possibilitar a obtenção de resultados seguros e pacíficos no universo polêmico da filosofia. Para tanto, indicaremos a importância de recuperar o papel que a tradição filosófica desempenha para o pensamento próprio, assim como (...) a importância de conscientizar-se de que a principal dificuldade da filosofia é estar diante dos conceitos sem pré-conceitos. Além disso, ressaltaremos a necessidade de superação das dificuldades humanas como a da vontade mostrando na filosofia de Wittgenstein a presença da atividade destruidora dos vícios, adornos e ídolos herdados bem como a sua importância para a averiguação das condições lingüísticas do próprio pensar.

En este artículo, y desde la sociología del trabajo, argumentamos que los recurrentes antagonismos entre sectores que defienden el medioambiente y los que defienden las fuentes de trabajo son una ficción política. Ello lo sustentamos en una reflexión ontológica-epistemológica desde donde se develan un encadenamiento de jerarquías, desigualdades, dominación y explotación, consagrado en la moderna ideología del desarrollo y progreso ilimitado, bajo cuyo eje se plantea una ficticia comunión de intereses en la que trabajo y capital comparten iguales anhelos de (...) progreso y éxito. Una ficción que resulta ser una estrategia política-ideológica que configura a las/os defensores del medioambiente como antagónicos al desarrollo y creación de fuentes de trabajo, tal como se revela en la industria del salmón del sur de Chile, abordada aquí como un caso “testigo”. Esta estrategia política adquiere pleno sentido en países como Chile, donde hoy se observa un doble y creciente proceso de “precarización de la naturaleza” y “naturalización de la precariedad laboral”.

Sport poses a number of important and no less significant questions, which, on the face of it, may not necessarily seem very important or significant to begin with – a peculiarity that we believe to be integral to sport itself. This article introduces, explores and outlines the psychoanalytic significance of this peculiarity. It explores how the emotions stirred by sport are intertwined with a realm of fiction and fantasy. Despite its lack of practical utility, sport carries an undeniable gravity, encapsulating (...) the aspirations of communities, nations and continents. As a result, psychoanalysis can be used to critically reflect on the purpose and meaning of sport: that is, why do we need sport, and why, for large sections of the world’s population, do we rely on it? Ultimately, while psychoanalysis maintains a unique relation to a variety of unexpected fields of study – including art, culture and neuroscience – we seek to add to this expanding list of inquiry by including sport in this critical domain. By utilising sport as a platform to elucidate psychoanalytic concepts, it is recognised that sport can also prompt questions for psychoanalysis. In so doing, theoretical discussions on the social, cultural and political dimensions of sport through psychoanalytic theory are introduced and applied. (shrink)

Cinema is commonly hailed as "the universal language," but how does it communicate so effortlessly across cultural and linguistic borders? Drawing on a lifetime's worth of viewing an reviewing, influential critic Gilberto Perez invokes a dizzying array of masters past and present includin Chaplin, Ford, Kiarostami, Eisenstein, Malick, Mizoguchi, Haneke, Hitchcock, and Godard--to explore the transaction between filmmaker and audience. The Eloquent Screen shows how cinema, as the consummate contemporary art form, establishes a thoroughly modern rhetoric in which different (...) points of view are brought into clear focus.".

RESUMEN Se expone críticamente una interpretación reciente del hedonismo epicúreo, según la cual este podría comprenderse como hedonismo actitudinal. Esta lectura conlleva ciertas tensiones internas y descuida el sentido fundamental del epicureismo, esto es, que se trata de una teoría del bienestar prudencial. Al examinar solo este aspecto, se omiten ciertos problemas secundarios, como la legitimidad de interpretar de manera actitudinal una doctrina asentada en el atomismo. ABSTRACT The paper offers a critical review of a recent interpretation of Epicurean hedonism, (...) according to which the latter could be understood as an attitudinal hedonism. Such reading implies certain internal tensions and neglects the fundamental meaning of Epicureanism as a theory of prudential well-being. By focusing exclusively on one aspect, that reading omits certain secondary issues, such as the legitimacy of an attitudinal interpretation of a doctrine grounded in atomism. (shrink)

Resumo O objetivo deste artigo é apresentar os temas do “novo método” filosófico e da “Filosofia da Psicologia”, nos escritos tardios de Ludwig Wittgenstein, como relacionados prática e necessariamente. Para o proposto, a estratégia expositiva segue a seguinte ordem: analisam-se os pressupostos filosóficos relativamente irrefletidos que determinam a visão que o jovem Wittgenstein tinha do “método correto da Filosofia” e da “Filosofia da Psicologia”; interpreta-se a volta filosófica de 1929 como comprometida em apresentar o rosto ainda informe do “novo método” (...) e retomar criticamente os alvos do TLP, sob essa nova perspectiva metodológica; e considera-se a Filosofia da psicologia de Wittgenstein inserida numa perspectiva diferente da perspectiva da ciência psicológica do fim do século XIX e início do século XX, fundamentada em investigações empíricas. Essas observações constituem propriamente uma prática do “novo método” de apresentação perspícua e se caracteriza como um aspecto-chave e necessário, um filtro, para a compreensão das observações do filósofo em torno da psicologia e de seu objetivo em dissolver os problemas metafísicos ali presentes.The main purpose of this article is to present the themes of the philosophical “new method” and the “philosophy of psychology” in Ludwig Wittgenstein’s late writings as practically and necessarily related. For the proposed, our expository strategy follows the following order: we analyzed the relatively unreasonable philosophical presuppositions that determine the young Ludwig’s view of the “correct method of philosophy” and of “philosophy of psychology”; we interpreted the philosophical turn of 1929 as committed to presenting the still-informed face of the “new method” and to critically revisiting the TLP targets under this new methodological perspective; and we considered Wittgenstein’s philosophy of psychology inserted in a different perspective from the perspective of the psychological science of the late nineteenth and early twentieth century based on empirical investigations. These observations are properly a practice of the “new method” of perspicuous presentation and they are characterized as a key and necessary aspect, a filter, for the understanding of the philosopher’s observations about psychology, and his goal in dissolving the metaphysical problems present there.

This paper investigates whether 'even if A, B' is pragmatically polysemic, so that a nonconcessive conditional may have 'even if', and whether concessive conditionals, pragmatically defined, can fail to have 'even if' or a non-temporal 'still'. Different paraphrases are used to help elucidate pragmatic meanings. A theory of the pragmatic meanings of concessive and implicative conditionals is presented. The semantic meaning of 'even if' and the question of whether concessive conditionals imply the truth of their consequents are also discussed.

Este artigo tem o objetivo de desvelar o núcleo da forma das relações socioeconômicas no sistema capitalista de exploração para acumulação de propriedade privada. Referido núcleo deriva nos sujeitos de direito, no Estado e nas demais instituições que derivam do modo de produção posto pela classe socioeconômica dominante que detém a propriedade privada dos meios de produção. Por meio do método materialismo histórico-dialética em Karl Marx e sob a ótica da interpretação filosófica e científica de Evguiéni Bronislavovitch Pachukanis e especialistas (...) contemporâneos. A derivação do modo de produção interpela a forma das relações socioeconômicas. A forma direito forjada com a ideologia capitalista trata formalmente todos os sujeitos como se fossem iguais, equivalendo-os como sujeitos de direito, com a autorização ideológica da forma Estado, em que ambas as formas conformam-se ao poder político da burguesia. O núcleo das relações socioeconômicas tem como átomo a mercadoria, as mercadorias não possuem valor de uso, mas sim valor de troca. Ninguém tem o direito de usar um bem necessário para sua vida, mas somente se puder contratar essa mercadoria. Logo, não somos sujeitos de direito, somos sujeitos pelo direito, ou seja, somos uma mercadoria no sistema capitalista a ser explorada pela classe proprietária dos meios de produção. (shrink)

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum value (...) for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness. (shrink)

It is argued that contraposition is valid for a class of natural language conditionals, if some modifications are allowed to preserve the meaning of the original conditional. In many cases, implicit temporal indices must be considered, making a change in verb tense necessary. A suitable contrapositive for implicative counterfactual conditionals can also usually be found. In some cases, the addition of certain words is necessary to preserve meaning that is present in the original sentence and would be lost or changed (...) in the contrapositive without them. A distinction is made between adding new meaning and adding new words to preserve existing meaning. For concessive conditionals and relevance conditionals, however, no valid contrapositive can be found. They do not belong to the class of contraposable conditionals, which can be independently defined. Difficult cases are also discussed in which the contradictory of the consequent semantically entails the truth of the antecedent. In such cases the content of the antecedent is implicit in the meaning of the consequent. Contraposition becomes possible if what is implicit in the original consequent is made explicit in the contrapositive antecedent. (shrink)

"Tough, smart, superbly engaging, The Material Ghost is a terrific book." -- Edward W. Said In The Material Ghost , Gilberto Perez draws on his lifelong love of the movies as well as his work as a film scholar to write a lively, wide-ranging, penetrating study of films and filmmakers and the nature of the art form. For Perez, film is complex and richly contradictory, lifelike and dreamlike at once, a peculiar mix of reality and imagination. "The images on (...) the screen," he writes, "carry in them something of the world itself, something material, and yet something transposed, transformed into another world: the material ghost." "Dazzling... The sheer intelligence at work in these lucid pages is exhilarating." -- Alfred Guzzetti, Boston Book Review "A pleasure. Gilberto Perez is one of the smartest film critics writing anywhere." -- Jonathan Rosenbaum "Strikes an ideal balance between insightful analysis and graceful writing... A model of thoughtful criticism." -- David Sterritt, Christian Science Monitor "Brilliantly polemical in his critique of cynical reason ('the official philosophy of late capitalism'), no less passionate in defending the truth-value of cinema, Perez seems to be the clearest heir to the great humanist critic André Bazin." -- Sight & amp Sound "The chapters on Keaton and Renoir are stunning, full of perceptive remarks the chapter on Godard is a persuasive rehabilitation none of the chapters is without memorable insights." -- Michael Wood, London Review of Books "Gilberto Perez's ambitious, abundant, and cultivated book--the fruit of decades of thinking and teaching -- accompanies readers on a journey of discovery into the wonder of film." -- Stanley Cavell "Few books of film criticism in the past twenty-five years have been so enjoyable or instructive... [Perez] has excellent things to say about authorship, about documentaries, about popular genres, about cinematic point of view and narrative technique, about actors, and above all about camera style... He makes us want to look once more at the remarkable pictures he discusses." -- James Naremore, Cineaste. (shrink)

Este artículo examina el significado y la función de las metáforas en la configuración del conocimiento, las percepciones y decisiones en el ámbito de la salud. Al analizar críticamente su impacto tanto positivo como negativo, especialmente en la relación entre profesionales de la salud y pacientes, se proponen tres dimensiones para desentrañar su significado: la política, que las examina como agentes de poder y como instrumento para la legitimación de las desigualdades; la cultural, que considera las metáforas como sedimentos culturales (...) que desafían el conocimiento biomédico predominante; y la ética, que cuestiona las implicaciones morales de las narrativas construidas. Este enfoque holístico busca mejorar la comprensión de la interacción compleja entre lenguaje, cognición y experiencia de enfermedad, promoviendo aproximaciones más completas en el ámbito de la salud.

1. Introduction The readiness potential was found to precede voluntary acts by about half a second or more (Kornhuber & Deecke, 1965). Kornhuber (1984) discussed the readiness potential in terms of volition, arguing that it is not the manifestation of an attentional processes. Libet discussed it in relation to consciousness and to free will (Libet et al. 1983a; 1983b; Libet, 1985, 1992, 1993). Libet asked the following questions. Are voluntary acts initiated by a conscious decision to act? Are the physiological (...) facts compatible with the belief that free will determines our voluntary acts? What is the role of consciousness in voluntary action? In this paper I will discuss these questions and the answers that Libet gave to them. (shrink)

In the Poetics of Aristotle there is a definition of the human being that perhaps has not yet been well considered in educational theory and practice. This definition calls into question a dynamism that according to Plato was unavoidable for an appropriate understanding of the educational process that turns a human being into a beautiful, good and just citizen: mimesis. The paper's intent is to reconsider the definition of the human being, centred on mimesis, presented by Aristotle in the Poetics (...) to demonstrate if, and how, it might establish new paradigms for human coexistence. Aristotle's anthropological statement is included in a much wider discourse concerning philosophy of art; but if isolated from the context, it is an essential definition of human beings that can be synthesised as follows: human beings are the mimetic animal par excellence, and their process of understanding has a fundamental connection with such excellence. Ignorance and/or negligence of how relevant mimesis might be in the educational process may have decisively contributed to separate human beings from this core aspect of their humanity and therefore produced painful consequences in human coexistence. As long as education does not pay attention to the pedagogical implications of the definition taken from the Poetics, how can human flourishing be safeguarded? I argue that recognition of the centrality of mimesis in the educational process allows human edification to proceed devoid of ideological basis, be it secular or confessional; and overcomes the risk of relativism. Mimesis, formerly recognised by Plato as a link between what is expressed and what really is, is masterfully reinterpreted by Aristotle. Aristotle recognised its positive pedagogic value in the Poetics, and nowadays we can recognise how it offers existential dynamics that restore the vital human relationship between self and other. The sense of this proposal lies in giving mimesis the role it deserves in education, by raising the significance of how coexistence might benefit from a vast human dimension, capable of recognising our humanity beyond our rational capacity.

Claims that necessary and sufficient conditions are not converse relations are discussed, as well as the related claim that If A, then B is not equivalent to A only if B . The analysis of alleged counterexamples has shown, among other things, how necessary and sufficient conditions should be understood, especially in the case of causal conditions, and the importance of distinguishing sufficient-cause conditionals from necessary-cause conditionals. It is concluded that necessary and sufficient conditions, adequately interpreted, are converse relations in (...) all cases. (shrink)

Libet's (2000) arguments in defense of his interpretation of his experimental results are insufficient. The claims of my critical review (Gomes, 2008) do not suffer with his new statements.

O autor apresenta alguns princípios da clínica winnicottiana através da discussão do artigo de Winnicott de 1941 intitulado "A observação de bebês em uma situação estabelecida". Enfatiza a dimensão do tempo como fator fundamental na situação clínica. A situação clínica organiza-se ao redor do gesto, da ação, do acontecer do self. Por essa razão a intervenção do analista aborda fundamentalmente a ação no mundo. Desde as primeiras sessões é importante permitir que o gesto do paciente crie o final da sessão, (...) para que haja um trabalho de construção da finalização da análise e do morrer, como parte da saúde.The author presents some of the principles of the winnicottian clinic through the discussion of Winnicott's article of 1941 "The observation of Infants in a Set Situation".

A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main conclusions are (...) favored, but her explanation of peripheral–lemniscal couplings is found to be unconvincing. Trevena and Miller's article unsuccessfully tries to rescue a dualist interactionist view. Libet's method of timing intentions is thoroughly criticized. (shrink)

This paper investigates the implicative conditional, a connective intended to describe the logical behavior of an empirically defined class of natural language conditionals, also named implicative conditionals, which excludes concessive and some other conditionals. The implicative conditional strengthens the strict conditional with the possibility of the antecedent and of the contradictory of the consequent. $${p\Rightarrow q}$$ p ⇒ q is thus defined as $${\lnot } \Diamond {(p \wedge \lnot q) \wedge } \Diamond {p \wedge } \Diamond {\lnot q}$$ ¬ ◊ (...) ( p ∧ ¬ q ) ∧ ◊ p ∧ ◊ ¬ q. We explore the logical properties of this conditional in a reflexive normal Kripke semantics, provide an axiomatic system and prove it to be sound and complete for our semantics. The implicative conditional validates transitivity and contraposition, which we take to be integral parts of reasoning and communication. But it only validates restricted versions of strengthening the antecedent, right weakening, simplification, and rational monotonicity. Apparent counterexamples to some of these properties are explained as due to contextual factors. Finally, the implicative conditional avoids the paradoxes of material and strict implication, and validates some connexive principles such as Aristotle’s theses and weak Boethius’ thesis, as well as some highly entrenched principles of conditionals, such as conjunction of consequents, disjunction of antecedents, modus ponens, cautious monotonicity and cut.

A theory of necessary and sufficient conditions is presented, as well as a theory of necessary and sufficient causes and effects, viewed as a particular case of the former. Ambiguities of the terms 'condition' and 'necessary condition' are explored, and a neutral meaning for 'condition' is favoured. The relation between necessary and sufficient conditions and implicative conditionals (including counterfactuals) is also discussed. Two problems of counterfactual theories of causal explanation are indicated, concerning (i) how to account for causes that are (...) not necessary and (ii) how to interpret the counterfactual from the negation of the effect to the negation of the cause. Application of the theory of necessary and sufficient conditions to Euler’s explanation of the Königsberg bridge problem is discussed. The theory of necessary and sufficient causes and effects is then applied to the flagpole shadow explanation and to two biological explanations, one involving a sufficient but not necessary cause and the other a necessary but not sufficient cause. Causes that are neither sufficient nor necessary are also recognized. Finally, a probabilistic approach to causes that are either not sufficient or not necessary is explored, including its application to examples of such cases. (shrink)

The analysis is restricted to the architectural aspect. It puts in evidence a dialectical procedure which makes the gnoseological importance of the verb to look stand out clearly. The pharisee's knowledge is based on religious convictions ; that of the blind man on his experience.
