El trabajo analiza las consecuencias que genera la mayor presencia de China en el eje estratégico argentino-brasileño. El análisis se centra en la década que transcurre entre el 2004 y el 2014. En esa etapa coincide la expansión de China con los cambios de gobierno en Argentina y Brasil. Los dos gobiernos fueron cuestionadores del modelo neoliberal y acordaron algunas líneas de acción. Se analizan las relaciones comerciales y los acuerdos de asociación estratégica con China y las consecuencias que se (...) han generado. El estudio señala que los cambios de gobierno fueron políticamente funcionales a las necesidades sistémicas planteadas por China. (shrink)

§ 1. Introduction. Perhaps the most surprising recent development in complexity theory is the discovery that the class NP can be characterized using a form of randomized proof checker that only examines a constant number of bits of the “proof” that a string is in a language [6, 5, 31, 3, 4]. More specifically, writing ∣x∣ for the length of a string x, a language L in the class NP of languages recognizable in Nondeterministic polynomial time is traditionally given by (...) a polynomial p and a polynomial-time predicate P such that a string x is in L iff there is some string y satisfying P, where ∣y∣ ≤ p. Intuitively, we can think of a string y as a possible proof that x ϵ L, with the predicate P some kind of proof checker that distinguishes good proofs from bad ones. A string x is therefore in a language L ϵ NP if there is a short proof that x ϵ L, and not in L otherwise. The surprising discovery is that the deterministic proof checker that reads the entire input and proof can be replaced by a probabilistic verifier that on input x and possible proof y, where y is presented in a certain way, flips at most O coins and reads at most a constant number of bits of x and y. Obviously, a probabilistic verifier that does not read the whole proof will sometimes make mistakes. However, the surprising and essentially non-intuitive mathematical fact is that for each language L in NP, it is possible to find a polynomial q and verifier V flipping a logarithmic number of coins and reading a constant number of bits such that, for any x ϵ L, there exists y with ∣y∣ ≤ q and with V accepting with probability 1 and, for x ∉ L, there is no y with ∣y∣ ≤ q and with V accepting with probability ≥ 1/4. This idea canalsobeextended to PSPACE [10, 9], using a game that alternates between two players instead of a proof presented by a “single player.”. (shrink)

The Dialectical Path of Law discusses the origin of law leading to the development of advanced corporate law intertwined with the formation of technical tax rules. Lincoln explores the recent developments of the OECD and United States tax rules within a hardly discussed context in legal academia - the Hegelian dialectic.

The political upheavals of China's Warring States period proved to be intellectually fertile, giving rise to one of history's greatest flowerings of political philosophy. The most eminent thinkers of the day sought to articulate models for good government amidst the ruins of the Zhou dynasty. Zhuangzi, on the other hand, appears to many readers to eschew these political questions. In this article, however, I contend that the Zhuangzi has a more practical political teaching than has often been appreciated. It is (...) intended to help others to navigate the treacherous political waters in which they might well find themselves, particularly in an era of profound instability, by teaching them how to understand their own...

The replication crisis has prompted many to call for statistical reform within the psychological sciences. Here we examine issues within Frequentist statistics that may have led to the replication crisis, and we examine the alternative—Bayesian statistics—that many have suggested as a replacement. The Frequentist approach and the Bayesian approach offer radically different perspectives on evidence and inference with the Frequentist approach prioritising error control and the Bayesian approach offering a formal method for quantifying the relative strength of evidence for hypotheses. (...) We suggest that rather than mere statistical reform, what is needed is a better understanding of the different modes of statistical inference and a better understanding of how statistical inference relates to scientific inference.

How will the adoption of genetically modified staple crops reconfigure labor processes in Sub-Saharan Africa? This article focuses on Uganda, where GM varieties of matooke, the country’s primary carbohydrate staple, are expected to be commercialized within the next few years. The paper draws on survey data and focus groups with a random sample of over one hundred and fifty growers to investigate the potential ways a variety engineered to be resistant to banana bacterial wilt might impact labor dynamics. A BBW (...) resistant GM variety will displace labor currently allocated to disease prevention and control, and increase the labor required for harvesting higher yields. How farmers can address the need for more harvesting labor varies significantly according to region. In the southwestern highlands, producers can increase their portion of hired labor. In the central and eastern regions, where farms tend to be smaller and subsistence-oriented, farmers are more likely to intensify their use of unpaid family labor, particularly that of wives. Hence, while GM technology may result in increased yields for small-scale farmers in Uganda, this is likely to come at the cost of intensifying the agricultural labor burdens of women in the central and eastern region.

Linear logic, introduced by Girard, is a refinement of classical logic with a natural, intrinsic accounting of resources. This accounting is made possible by removing the ‘structural’ rules of contraction and weakening, adding a modal operator and adding finer versions of the propositional connectives. Linear logic has fundamental logical interest and applications to computer science, particularly to Petri nets, concurrency, storage allocation, garbage collection and the control structure of logic programs. In addition, there is a direct correspondence between polynomial-time computation (...) and proof normalization in a bounded form of linear logic. In this paper we show that unlike most other propositional logics, full propositional linear logic is undecidable. Further, we prove that without the modal storage operator, which indicates unboundedness of resources, the decision problem becomes PSPACE-complete. We also establish membership in NP for the multiplicative fragment, NP-completeness for the multiplicative fragment extended with unrestricted weakening, and undecidability for fragments of noncommutative propositional linear logic.

Rice, Lincoln Review of: The problems of evil and suffering, by John Cowburn , pp. 264.

In lieu of an abstract, here is a brief excerpt of the content:An Epiphany in Munich LINCOLN PERRY W hen I used to say the sentence (softly and to myself ) “I hate palms” or “Palms are not beautiful; possibly they are not even trees,” it was a composite palm that I had somehow succeeded in making without even ever having seen, close up, many particular instances. Conversely, when I now say, “Palms are beautiful,” or “I love palms,” it (...) is really individual palms that I have in mind. This quote from Elaine Scarry’s On Beauty and Being Just applies perfectly to an experience I recently had regarding a painting by an artist I had assumed I didn’t much care for. Perhaps it would be best to lead into my epiphany gradually, to recreate the preparation that might have been necessary to have my realization. Actually, I speak of a double epiphany, in that it was shared by the friend I was travelling with when we saw the artwork in question. He and I are both painters, and have much in common, both in terms of our own work and our voracious appetite for seeing museums, so when I planned a trip for late October 2018 to see thirty museums in two weeks in Germany and Austria, I knew just whom to call. David Carbone and I have known each other, and appreciated each other’s work, since leaving graduate school in 1975, meeting at the College Art Association held that year in Washington, DC, where people compete for jobs while trying to maintain a veneer of civility. David made less of an effort than most, and I vividly remember him in saddle shoes he had painted bright blue, wearing a tie featuring a burlesque dancer, sipping champagne in the garden courtyard of the National Gallery. All the nearby aspiring art historians were immaculately dressed and scrupulously behaved, but David finished his drink, and in imitation of a arion 27.1 spring/summer 2019 Russian toast, threw his empty glass against the wall, where it noisily shattered. I like this guy, thought I. Over the next few days, visiting DC’s museums together, I recognized the brilliance of his commentaries on the art we saw. And his wit: He told of studying with his painting professor, who became frustrated with David’s pace in painting and said “David, painting is really very simple!” The reply: “But, what if you’re not simple?” I can’t conjure a single artist about whose work we’ve disagreed in the course of the fortythree years we’ve known each other. Meeting often in New York, where he lives with his wife Donna (who, like my wife, is always perfectly willing to let us go museum schlepping without them), we’ve also travelled in central Italy, and even flew to Fort Worth to see a show of the Le Nain brothers. A very sweet guard there asked us, “Who ARE you?” and when we said we were painters, she said, “Oh, because I’ve never seen anybody look at paintings this long, or talk about them so much!” Berlin is a treasure trove, where we visited ten fine museums, then flew to Vienna, which was hosting an extensive exhibit of Bruegel’s paintings, though feast might be a more apt word. A visual feast, but one that didn’t leave one sated, jaded, or bloated, but rather improved, made less ambivalent about membership in a questionable species. Yes, the viewer consumed a meal of war, famine, foolishness, and pride, but the chef made it not just palatable but beautiful, thought-provoking and humorous. Bruegel and his contemporary Rabelais seem kindred spirits, skeptical but amused, bawdy but tender, creating not just works but micro to macro worlds, an alternate world view, in fact. Each painting mesmerized anyone looking long and carefully enough, discovering that a tiny girl on a sled is able to get a purchase on the ice not just with her diminutive sticks, but by the miniscule iron nails in which they end, painted with a one hair-brush. From this minutia we graduate to a wider and wider view, one that comes to imply infinity. Bruegel’s brilliant guidance doesn’t confront us... (shrink)

Kelly Brown Douglas offered two countermeasures to aid ethicists in expanding the moral imaginary of a people: (1) examine critically the work of interlocutors and (2) change our gaze to those voices that have been traditionally refused epistemic authority. This essay explores concrete examples of these countermeasures in theological scholarship.

This book examines environmentalist thought through its connections to ancient philosophies and religions and a lineage which runs through romantic art and nineteenth-century science. The examination is conducted from a broad and skeptical utilitarian point of view.

"Nearly all the essays are theoretically informed, argumentative, and exceptionally interesting; nearly all try to paint the merits (and demerits) of utilitarianism as a political philosophy in the light of attempted solutions to theoretical problems that are explored in some detail. The result is a searching, thoughtful volume." --Ethics "The Utilitarian Response is unique in the breadth of problems and questions in utilitarian theory covered. It is more suggestive of strategies by which contemporary utilitarianism could be improved than a comprehensive (...) reply to recent objections to utilitarianism. It should be of great interest to scholars in ethical theory and political philosophy. It would also serve well as a text for a graduate level seminar, if accompanied with readings in the area of recent objections to utilitarianism." --Utilitas Utilitarianism is an important component of both popular and academic responses to the problems of ethics and public policy. Over the past two decades, it has lost some ground to rival theories, such as: contractarian, libertarian and natural rights. This book explores the capacity of utilitarianism and the existing challenge of reviving it in political theory. Primary attention is given to questions on the intellectual coherence and moral acceptability of utilitarian responses to practical dilemmas, including health care, punishment, and electoral arrangements. Also examined are the relationships between private ethics and public policy, utility and freedom, utility and democracy, and the role and limitations of states, both locally and internationally. The Utilitarian Response is a broad and contemporary account of utilitarian theory as it exists today. It explores the continuing applicability of utilitarian thought to current practical and interrelated issues of ethics, economics, and politics. An ideal resource for scholars in political philosophy and political theory. (shrink)

Recent theory suggests that action prediction relies of a motor emulation mechanism that works by mapping observed actions onto the observer action system so that predictions can be generated using that same predictive mechanisms that underlie action control. This suggests that action prediction may be more accurate when there is a more direct mapping between the stimulus and the observer. We tested this hypothesis by comparing prediction accuracy for two stimulus types. A mannequin stimulus which contained information about the effectors (...) used to produce the action and a point stimulus, which contained identical dynamic information but no effector information. Prediction was more accurate for the mannequin stimulus. However, this effect was dependent on the observer having previous experience performing the observed action. This suggests that experienced and na¨ıve observers might generate predictions in qualitatively difference ways, which may relate to the presence of an internal representation of the action laid down through action performance.

Refletimos sobre educação, ética e suas relações com consumo, ambiente e vida. Discutimos criticamente a sociedade globalizada cujas relações socioambientais se baseiam no individualismo e na competitividade.

Bruineberg and colleagues highlight work using Markov blankets to demarcate the bounds of the mind. This echoes earlier attempts to demarcate the bounds of the mind from a dynamical systems perspective. Advocates of mechanistic explanation have challenged the dynamical approach to independently motivate the application of the formalism, a challenge that Markov blanket theorists must also meet.

Mormon Transhumanism is the idea that humanity should learn how to be compassionate creators. This idea is essential to Mormonism, which provides a religious framework consistent with naturalism and supportive of human transformation. Mormon Transhumanists are not limited to traditional or popular accounts of religion, and embrace opportunities and risks of technological evolution. Although usually considered secular, Transhumanism originates partly in religious Humanism and sometimes functions as religion. Accelerating change contextualizes Mormon Transhumanist narratives, which illustrate parallels between Mormonism and Transhumanism. (...) Mormon Transhumanists have produced secular arguments for faith in God and religious arguments for Transhumanism. This is a revision and update of “What Is Mormon Transhumanism?”. (shrink)

Para abordar a questão moral do aborto de fetos sem cérebro, inicialmente são apresentados e considerados insatisfatórios dois argumentos que defendem a punição para a gestante que aborta: a sacralidade da vida e a atribuição ao feto do caráter de “pessoa”. Em seguida, são apresentados e considerados satisfatórios quatro argumentos contra a punição da gestante: a morte certa do feto, o caráter terapêutico e não-eugênico do aborto, o sofrimento, sem fi nalidade evidente, dos envolvidos na situação e o direito da (...) mulher sobre seu corpo. Na terceira seção, discutem-se as exigências da compaixão. Chega-se à conclusão de que abortar ou não fetos anencefálicos deve ser uma decisão individual, não coletiva, que deveria ser tomada por cada mulher, e não pelo Estado democrático e então imposta às mulheres. A mulher tem o direito moral tanto de continuar quanto de interromper a gravidez de fetos anencefálicos. To approach the moral issue of the abortion of anencephalic fetuses, we fi rstly present and consider unsatisfactory two arguments for the punishment of the pregnant woman who makes an abortion: that of the sanctity of life and of the attribution of the status of a person to the fetus. After that, we present and consider satisfactory four arguments against the punishment of the pregnant woman: the certain death of the fetus, the therapeutic and non-eugenic character of the abortion, the inutility of the suffering brought by the situation to the woman and other people and the woman’s right over her body. On the third section, we discuss the demands for compassion. The conclusion is that the decision about the abortion of anencephalic fetuses should be an individual decision and not a collective one; it should be made by each woman, not by the democratic Estate and then imposed on women. The woman has the right of interrupting and of continuing the pregnancy of an anencephalic fetus. (shrink)
