Developed by Arthur Prior, Temporal Logic allows to represent temporal information on a logical system using modal operators such as P, F, H or G, whose intuitive meaning is “it was sometime in the Past...”, “it will be sometime in the Future...”, “it Has always been in the past...” and “it will always Going to be in the future...” respectively. Valuation of formulae built from these operators are carried out on Kripke semantics, so Modal Logic and Temporal Logic are consequently (...) related. In fact, Temporal Logic is an extension of Modal one. Even when both logics mechanisms are able to formalize modal-temporal information with some accuracy, they suffer from a lack of expressiveness which Hybrid Logic can solve. Indeed, one of the problems of Modal Logic consists in its incapacity of naming specific points inside a model. As Temporal Logic is based on it, it cannot make such a thing neither. But First-Order Logic does can by means of constants and equality relation. Hybrid Logic, which results from combining Modal Logic and First-Order Logic, may solve this shortcoming. The main aim of this paper is to explain how Hybrid Logic emanates from Modal and Temporal ones in order to show what it adds to both logics with regard to information representation, why it is more expressive than them and what relation it maintains with the First-Order Correspondence Language.

George Rupp's Beyond Existentialism and Zen, in its typological-structural analysis and model of religious pluralism, proffers an alternative to the dominant Kantian models (e.g., by John Hicks and Sarvepalli Radhakrish- nan). The question for Rupp is not which religion is true and how to decide that issue-answered in the Kantian approach in terms of an unknowable Ding an sich that all religions, albeit imperfectly, try to approximate or conceptualize (i.e., God or the Transcendent)-but rather how do religions represent, at least (...) in principle, a structural possibility for salvation or human flourishing, however different and incompatible their distinct prima facie truth claims might be. Although the potential for a radically relativistic model is implicit in Rupp's approach, it is argued here that his Hegelian assumptions lead him to accept relativism only in a provisional ("critical") way; for Rupp, under ideal epistemic conditions (e.g., the Peircian "end of inquiry"), one final conceptualization of ultimate reality will emerge as absolute truth. In the final part of this essay a version of the relativistic model implicit in Rupp's approach is defended against both the Kantian model of Hicks et al. and Rupp's Hegelian-Peircian model, which, it is argued, is incompatible certainly with the spirit of his own typological-structural analysis, if not with the letter. In challenging what Rupp calls the truth of Zen, it is further argued that not only is more than one salvific structural possibility available to us through the different world religions but also that realizing these possibilities is principally a human responsibility, and that the cosmos is quite indifferent to and compatible with several possibilities, from the most destructive to the most conducive to human well-being and flourishing.

Este documento analiza cómo se presenta la deshumanización en los conflictos armados e intenta demostrar que, en la mayoría de los casos, lo ‘discursivo’ y lo ‘violento’ coexisten de modo que el ‘otro’ es una construcción difusa que cambia según el contexto. Como consecuencia, no puede establecerse una división clara entre ‘enemigo’ y ‘adversario’, por lo que debe aceptarse que dicha relación es mucho más compleja. Para esto, se revisa la historia del conflicto armado colombiano desde mediados del siglo XX, (...) usando la teoría posestructuralista del discurso de Chantal Mouffe y Ernesto Laclau, y el concepto de lo ‘político’ de Carl Schmitt.

This work presents results of improvement in the productivity of Arthrospira platensis in a company dedicated to its production. The six sigma methodology was applied in production processes that require the use of bioreactors. Starting from the analysis of the current state, aspects, physical and chemical variables that directly influence the productivity achieved were identified. Various culture media were tested and subsequently scaled for industrial production. In addition, the incorporation of carbon into the culture medium was controlled, optimizing the range (...) of potential hydrogen pH. The identified parameters were measured and six sigma methodology strategies were assigned. An improvement in productivity corresponding to 66% was verified with the same quality of final product.

The aim of this study was to assess the predictive capacity of some of the most relevant cognitive skills pertaining to the academic field as measured by the Spanish Primary School Aptitude Test Battery. This psychometric tool was applied to all students who were enrolled in the final year of Early Childhood Education in the public schools of the province of Alicante and a follow-up of their academic progress was carried out when they completed Primary Education. The results obtained show (...) that medium-high and high scores in Verbal Aptitude and Numerical Aptitude tests in Early Childhood Education, can predict academic success at the end of Primary Education in instrumental subjects such as: Language and Mathematics. We have determined the importance of developing pedagogical programs that stimulate the development of these skills during Early Childhood Education, while implementing support strategies during Primary Education, for those students who present underdeveloped aptitudes in these areas. In this way, school difficulties would be prevented in the instrumental subjects that provide access to other academic areas. (shrink)

Aim: The present work proposes the study of the neuromotor activity of the masseter-jaw-tongue articulation during diadochokinetic exercising to establish functional statistical relationships between surface Electromyography, 3D Accelerometry, and acoustic features extracted from the speech signal, with the aim of characterizing Hypokinetic Dysarthria. A database of multi-trait signals of recordings from an age-matched control and PD participants are used in the experimental study. Hypothesis: The main assumption is that information between sEMG and 3D acceleration, and acoustic features may be quantified (...) using linear regression methods. Methods: Recordings from a cohort of eight age-matched control participants and eight PD participants were collected during the utterance of a diadochokinetic exercise. The dynamic and acoustic absolute kinematic velocities produced during the exercises were estimated by acoustic filter inversion and numerical integration and differentiation of the speech signal. The amplitude distributions of the absolute kinematic and acoustic velocities are estimated to allow comparisons in terms of Mutual Information. Results: The regression results show the relationships between sEMG and dynamic and acoustic estimates. The projection methodology may help in understanding the basic neuromotor muscle activity regarding neurodegenerative speech in remote monitoring neuromotor and neurocognitive diseases using speech as the vehicular tool, and in the study of other speech-related disorders. The study also showed strong and significant cross-correlations between articulation kinematics, both for the control and the PD cohorts. The absolute kinematic variables presents an observable difference for the PD participants compared to the control group. Conclusion: Kinematic distributions derived from acoustic analysis may be useful biomarkers toward characterizing HD in neuromotor disorders providing new insights into PD. (shrink)

In this book by the award-winning author of Just Healthcare, Norman Daniels develops a comprehensive theory of justice for health that answers three key questions: what is the special moral importance of health? When are health inequalities unjust? How can we meet health needs fairly when we cannot meet them all? Daniels' theory has implications for national and global health policy: can we meet health needs fairly in ageing societies? Or protect health in the workplace while respecting individual liberty? Or (...) meet professional obligations and obligations of justice without conflict? When is an effort to reduce health disparities, or to set priorities in realising a human right to health, fair? What do richer, healthier societies owe poorer, sicker societies? Just Health: Meeting Health Needs Fairly explores the many ways that social justice is good for the health of populations in developed and developing countries. (shrink)

Silence is reserved for what cannot be verbally expressed. The well-known Wittgensteinian quote summarizes an established understanding of the relationship between language and silence: because language is not enough to account for reality and thinking, it must be transcended by other means of expression, like music or silence. But what if the opposite is the case and silence is not the extension but the precondition of language, the ultimate source of meaning? This paper explores how this is the phenomenological and (...)

In the international bestseller, Thinking, Fast and Slow, Daniel Kahneman, the renowned psychologist and winner of the Nobel Prize in Economics, takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think. System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. The impact of overconfidence on corporate strategies, the difficulties of predicting what will make us happy in the future, the profound effect of (...) cognitive biases on everything from playing the stock market to planning our next vacation—each of these can be understood only by knowing how the two systems shape our judgments and decisions. -/- Engaging the reader in a lively conversation about how we think, Kahneman reveals where we can and cannot trust our intuitions and how we can tap into the benefits of slow thinking. He offers practical and enlightening insights into how choices are made in both our business and our personal lives—and how we can use different techniques to guard against the mental glitches that often get us into trouble. Winner of the National Academy of Sciences Best Book Award and the Los Angeles Times Book Prize and selected by The New York Times Book Review as one of the ten best books of 2011, Thinking, Fast and Slow is destined to be a classic.

It is common to hear talk of the aim of belief and to find philosophers appealing to that aim for numerous explanatory purposes. What belief 's aim explains depends, of course, on what that aim is. Many hold that it is somehow related to truth, but there are various ways in which one might specify belief 's aim using the notion of truth. In this article, by considering whether they can account for belief 's standard of correctness and the epistemic (...) norms governing belief, I argue against certain prominent specifications of belief 's aim given in terms of truth, and advance a neglected alternative.

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)

A pioneering work in the philosophy of mind, Content and Consciousness brings together the approaches of philosophers and scientists to the mind--a connection that must occur if genuine analysis of the mind is to be made.

This paperback edition contains a preface placing the book in the context of recent (...) work in the area. (shrink)

Higher education institutions worldwide have begun to embrace sustainability issues and engage their campuses and communities in such efforts, which have led to the development of integrity and ethical values in these organizations and their relationships with stakeholders.

The aforementioned research streams served as a context to explore best practices in sustainability on a global basis. (shrink)

The potential to collect brain data more directly, with higher resolution, and in greater amounts has heightened worries about mental and brain privacy. In order to manage the risks to individuals posed by these privacy challenges, some have suggested codifying new privacy rights, including a right to “mental privacy.” In this paper, we consider these arguments and conclude that while neurotechnologies do raise significant privacy concerns, such concerns are—at least for now—no different from those raised by other well-understood data collection (...) technologies, such as gene sequencing tools and online surveillance. To better understand the privacy stakes of brain data, we suggest the use of a conceptual framework from information ethics, Helen Nissenbaum’s “contextual integrity” theory. To illustrate the importance of context, we examine neurotechnologies and the information flows they produce in three familiar contexts—healthcare and medical research, criminal justice, and consumer marketing. We argue that by emphasizing what is distinct about brain privacy issues, rather than what they share with other data privacy concerns, risks weakening broader efforts to enact more robust privacy law and policy.

The question of how society should deal with social conflicts arising from cultural differences persists. Should we adopt an exclusivist approach by excluding reasons based on specific cultural traditions (culture-based reasons) from public debates about social policy, especially because these reasons do not appeal to the public at large? Or should we resort to an inclusivist approach by including reasons based on cultural traditions in public debate to give recognition to the diverse cultural identities of those who practice these traditions? (...) While these two approaches assign different roles to cultural traditions in public debate, both seem to welcome compromise between conflicting parties. This paper reviews contending normative approaches for dealing with conflicts in multicultural societies and explores the place of culture-based reasons in public debates designed to resolve conflicts.

The pessimistic hypothesis is the hypothesis that life is bad for us, in the sense that we are worse off for having come into existence. Suppose this hypothesis turns out to be correct — existence turns out to be more of a burden than a gift. A natural next thought is that we should stop having children. But I contend that this is a mistake; procreation would often be permissible even if the pessimistic hypothesis turned out to be correct. Roughly, (...) this is because we are often in a position to know that future people will approve of having been created, and their approval will not be inappropriate even if they are worse off for having been created. And our respect for the attitudes of future people can permit us to create them. (shrink)

Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. After motivating the need for some explanationist account, we raise (...) some problems for recent versions of explanationism. Learning from their failures, we then produce and defend a more resilient explanationism. (shrink)

Simon May has argued that the notion of a principled compromise is incoherent. Reasons to compromise are always in his view strategic: though we think that the position we defend is still the right one, we compromise on this view in order to avoid the undesirable consequences that might flow from not compromising. I argue against May that there are indeed often principled reasons to compromise, and that these reasons are in fact multiple. First, compromises evince respect for persons that (...) we have reason to think of as our epistemic peers, and acknowledgement of our own finitudes as moral reasoners. Second, compromises are often made morally necessary by the shortfalls that unavoidably separate democratic institutions from democratic ideals. Third, compromises express a desirable form of democratic community. And fourth, compromises are often justified from a consequentialist point of view, in that they allow for the realization of values that would not be realized as well by the failure to compromise.

El Anti-Excepcionalismo Lógico afirma que la Lógica es como cualquier otra ciencia. Si esta afirmación es cierta, entonces ella no sólo es revisable, sino que además todo lo que se puede decir sobre las ciencias aplica, mutatis mutandis, para la misma. El propósito de este artículo es explorar esta consecuencia del Anti-Excepcionalismo Lógico, acercando a la Filosofía de la Lógica el marco teórico de las Máquinas Nomológicas de Nancy Cartwright. De acuerdo con esta visión, lo que hay de verdadero en (...) las teorías científicas no está en el mundo sino en sus modelos: sistemas altamente controlados, estables, artificiales y específicos, dentro de los cuales se manifiestan regularidades sistematizables y enseñables. Mi afirmación es que lo mismo puede decirse de la Lógica: ella no captura las Leyes del Pensamiento o de la Razón, porque el pensamiento y la razón no están gobernados necesariamente por leyes. Sobre lo que sí puede decirse que versan las Leyes de la Lógica son metafísicas posibles: historias acerca de qué son las proposiciones, el pensamiento, la verdad y la validez. A fin de ilustrar y defender esta tesis, presento un ejemplo de Máquina Nomológica de la Lógica Clásica, basada en una lectura original del Tractatus de Wittgenstein, e investigo algunas de sus consecuencias. Mi conclusión es que esta imagen de la Lógica impacta en el problema de la revisión de la Lógica Clásica, en la medida en que muestra que dicha revisión no necesariamente responde a un proceso racional de adecuación de la teoría a los hechos porque los “hechos” relevantes no son anteriores a la teoría misma, sino que están moldeados y conducidos por ella.

" Qualia " is an unfamiliar term for something that could not be more familiar to each of us: the ways things seem to us. As is so often the case with philosophical jargon, it is easier to give examples than to give a definition of the term. Look at a glass of milk at sunset; the way it looks to you--the particular, personal, subjective visual quality of the glass of milk is the quale of your visual experience at the (...) moment. The way the milk tastes to you then is another, gustatory quale, and how it sounds to you as you swallow is an auditory quale; These various "properties of conscious experience" are prime examples of qualia. Nothing, it seems, could you know more intimately than your own qualia ; let the entire universe be some vast illusion, some mere figment of Descartes' evil demon, and yet what the figment is made of will be the qualia of your hallucinatory experiences. Descartes claimed to doubt everything that could be doubted, but he never doubted that his conscious experiences had qualia, the properties by which he knew or apprehended them. (shrink)
