In times of crisis, one of the areas heavily affected has been food, as a direct consequence of the damage caused to family farming and therefore to Food and Nutrition Security (SAN). Climate change, in turn, causes widespread crises, which, due to their impact on humanity, and above all, on SAN, provide complex humanitarian crises, worsening hunger. The military conflict imposes difficulties in access to food and production. This study aimed to critically describe the panorama of climate change and armed (...) conflicts in Africa, relating them to the pandemic of COVID-19 as a factor of aggravating the situation of food insecurity in African countries. A literature review study was carried out in various databases, journals and portals for this purpose, with emphasis on Google Scholar, CAPES and governmental portals. The results point to climate change, as being multicausal, and constitute a risk factor for agriculture and SAN, in African countries, characterized by the destruction of crops and the reduction of food availability. Armed conflicts makes difficult to produce and distribute food, especially for people who’s affected. (shrink)

Motor Imagery reproduces cognitive operations associated with the actual motor preparation and execution. Postural recordings during MI reflect somatic motor commands targeting peripheral effectors involved in balance control. However, how these relate to the actual motor expertise and may vary along with the MI modality remains debated. In the present experiment, two groups of expert and non-expert gymnasts underwent stabilometric assessments while performing physically and mentally a balance skill. We implemented psychometric measures of MI ability, while stabilometric variables were calculated (...) from the center of pressure oscillations. Psychometric evaluations revealed greater MI ability in experts, specifically for the visual modality. Experts exhibited reduced surface COP oscillations in the antero-posterior axis compared to non-experts during the balance skill. Experts further exhibited reduced length of COP displacement in the antero-posterior axis and as a function of the displacement area during visual and kinesthetic MI compared to the control condition. Predictive relationships were found between the stabilometric correlates of visual MI and physical practice of the balance skill, as well as between the stabilometric correlates of kinesthetic MI and the training experience in experts. Present results provide original stabilometric insights into the relationships between MI and expertise level. While data support the incomplete inhibition of postural commands during MI, whether postural responses during MI of various modalities mirror the level of motor expertise remains unclear. (shrink)

Conscious experiences in infants remain poorly understood. In this NeuroView, Passos-Ferreira discusses recent evidence for and against consciousness in newborn babies. She argues that the weight of evidence from neuroimaging and behavioral studies supports the thesis that newborn infants are conscious.

Este artigo analisa o conceito de fetichismo no interior da filosofia da música adorniana, a fim de mostrar como ele visa dar conta de uma ampla crítica aos processos de racionalização do material musical na modernidade ocidental. Para que o teor da crítica seja medido de maneira correta, devemos perceber como, no conceito adorniano de "fetichismo", convergem deliberadamente motivos de suas tradições de crítica ao fetichismo: a marxista e a psicanalítica. Tal estratégia nos permitirá compreender a razão pela qual o (...) conceito de mimesis é resgatado enquanto dispositivo de crítica ao fetichismo. (shrink)

El objetivo de este trabajo es analizar los ejemplos que se dan en las obras tradicionales del denominado καί estructural con el fin de determinar sus características desde una perspectiva más actual. Este es uno de los tipos de καί adverbial que se distinguen, pero, como veremos, se trata de una categoría compleja en la que, sobre la base de su aparición en una oración subordinada, se han mezclado al menos tres usos más o menos habituales de καί adverbial: aditivo, (...) identificativo y corresponsivo. The aim of this paper is to analyse the examples of the so-called structural καί from a modern perspective. The examples are taken from the traditional grammars, in which this adverbial use of καί is usually distinguished. As it will be shown, this is in fact a complex category, established on the basis of its appearance in a subordinate clause and including three quite common uses of adverbial καί: additive, identificational and corresponsive.

Soren Kierkegaard's Works of Love, a series of deliberations on the commandment to love one's neighbor, has often been condemned by critics. Here, Ferreira seeks to rehabilitate Works of Love as one of Kierkegaard's most important works. He shows that Kierkegaard's deliberations on love are highly relevant to some important themes in contemporary ethics, including impartiality, duty, equality, mutuality, reciprocity, self-love, sympathy, and sacrifice. Ferreira also argues that Works of Love bears on issues peculiar to a religious ethic, (...) such as the role of God as "middle term," and the possibility of preserving the aesthetic dimensions of love in a religious ethic of relation.

It is well known that Frege's system in the Grundgesetze der Arithmetik is formally inconsistent. Frege's instantiation rule for the second-order universal quantifier makes his system, except for minor differences, full (i.e., with unrestricted comprehension) second-order logic, augmented by an abstraction operator that abides to Frege's basic law V. A few years ago, Richard Heck proved the consistency of the fragment of Frege's theory obtained by restricting the comprehension schema to predicative formulae. He further conjectured that the more encompassing Δ11-comprehension (...) schema would already be inconsistent. In the present paper, we show that this is not the case. (shrink)

This paper is a defence of Lacan’s ontological interpretation of Freud’s theory of drive or instinct as being compatible with certain aspects in the way which Freud deals with the problem of drive or instinct in his own theory. According to Lacan, a negative ontology is the necessary compliment to Freud’s own considerations.

The aging process involves changes in immune regulation, i.e. adaptive immunity declines whereas innate immunity becomes activated. NF‐κB signaling is the master regulator of the both immune systems. Two recent articles highlight the role of the NF‐κB system in aging and immune responses. Adler et al1 showed that the NF‐κB binding domain is the genetic regulatory motif which is most strongly associated with the aging process. Kwon et al2 studying HIV‐1 infection and subsequent immune deficiency process demonstrated that HIV‐1 Tat (...) protein binds to SIRT1 protein, a well‐known longevity factor, and inhibits the SIRT1‐mediated deacetylation of the p65 component of the NF‐κB complex. As a consequence, the transactivation efficiency of the NF‐κB factor was greatly potentiated, leading to the activation of immune system and later to the decline of adaptive immunity. These observations support the scenario where immune responses and aging process can be enforced by the potentiation of NF‐κB transactivation efficiency. Longevity factors, such as SIRT1 and its activators, might regulate the efficiency of the NF‐κB signaling, the major outcome of which is inflamm‐aging via proinflammatory responses.

Arguments analogous to those found in the late medieval theory of the king’s two bodies, popularized by Ernst Kantorowicz, were resurrected in early nineteenth-century constitutional theories of the moderating powers of monarchy. Post-revolutionary French liberal thought, echoed by its Portuguese counterpart, rediscovered the virtues of the institution of royalty, notably the immaterial and immortal body of the king. This rediscovery was prompted by the uncertainties of different national political contexts which made many contemporaries believe it desirable to integrate restored monarchies (...) within modern constitutional models for state stability. This first occurred with the Bourbons’ return to post-Napoleonic France and the restoration of the monarchy in 1814, and then with the Braganza royal family’s return to Portugal in 1821 after thirteen years of rule from Brazil. Using arguments similar to those previously made in late medieval European political and legal thought, French and Portuguese liberals developed a theory of the king’s two powers, according to which the monarch at once exercised a moderating power, defined by the abstract institutional nature of the king’s person, and an executive power, embodied within his physical person. This conceptualization of royal duality was intended to make it possible to delegate executive power to ministers, leaving the king only the attributes of a largely symbolic power. Liberals thereby hoped to confine the monarch to his purely institutional body in a de-politicized constitutional role. (shrink)

The foundations of AI design discourse are worth analyzing. Here, attention is paid to the nature of theory languages used in designing new AI technologies because the limits of these languages can clarify some fundamental questions in the development of AI. We discuss three types of theory language used in designing AI products: formal, computational, and natural. Formal languages, such as mathematics, logic, and programming languages, have fixed meanings and no actual-world semantics. They are context- and practically content-free. Computational languages (...) use terms referring to the actual world, i.e., to entities, events, and thoughts. Thus, computational languages have actual-world references and semantics. They are thus no longer context- or content-free. However, computational languages always have fixed meanings and, for this reason, limited domains of reference. Finally, unlike formal and computational languages, natural languages are creative, dynamic, and productive. Consequently, they can refer to an unlimited number of objects and their attributes in an unlimited number of domains. The differences between the three theory languages enable us to reflect on the traditional problems of strong and weak AI. (shrink)

Continuing the task proposed in the first part, this paper intends to present a dialogue between Kant and Rousseau regarding the relationship between ethics and anthropology. In this second part, the present article intends to explore Kant's critical and original reading of Rousseau's anthropological-perfectibilist theory. Rousseau's work - or more precisely, his proposal for a theory of the human being - is decisive for the genesis of Kantian anthropology because it represents a turning point, according to our interpretative hypothesis, in (...) Kant's considerations not only about morality, but fundamentally about history and anthropology. (shrink)

Ao longo de sua obra, Karl Marx sempre manifestou preocupação com a particularidade do capitalismo em cada país. Nosso principal objetivo neste artigo é o de discutir algumas passagens da teorização marxiana acerca da constituição do capitalismo na Alemanha. Pretendemos fazer isso por meio da leitura imanente de alguns textos de Marx.

Empirical reports on scientific competition show that scientists can be depicted as self-interested, strategically behaving agents. Nevertheless, we argue that recognition-seeking scientists will have an interest in establishing methodological norms which tend to select theories of a high epistemic value, and that these norms will be still more stringent if the epistemic value of theories appears in the utility function of scientists, either directly or instrumentally.

In lieu of an abstract, here is a brief excerpt of the content:Hume's Natural History: Religion and "Explanation" M. JAMIE FERREIRA HUME'S BOLDLYSIMPLESTATEMENTof the genesis of religion--that "the anxious concern for happiness, the dread of future misery, the terror of death, the thirst for revenge, the appetite for food and other necessaries" led humankind to see "the first obscure traces of divinity"--is supported by appeals to what he considers plain common sense.' For example, given that at "the first origin (...) of society" (e4) our ancestors were obviously "ignorant and barbarous" (23), anxiously helpless in the face of threatening natural events--hence, obviously with neither the leisure nor the impulse nor the aptitude for serious reflection--it was obviously passionate fears and hopes, not reason, which motivated their beliefs. Given that the mind obviously "rises from inferior to superior," and that humankind obviouslyhasn't "inhabited palaces before huts and cottages or studied geometry before agriculture" (~4), polytheism obviously antedated monotheism. In the course of detailing his commonsensical account of the origin and development of religion, Hume highlights a wide variety of natural tendencies, principles, and propensities which are operative. Keith Yandell offers a recent reading of one such propensity at work in the origin of religion--namely, what Hume calls the "propensity of human nature, which leads into a system, that gives them some satisfaction" (29)--and Yandell explicitly takes it to be a propensity to an "explanatory" system.2 I want to argue in what follows that any reading of Hume's account of religion which highlights an explanatory motivation can be significantly misleading insofar as it obscures the way in which Hume's account differs markedly from other classical genetic accounts which emphasize explanation. ' The Natural History ofReligion, ed. H. E. Root (Stanford, CA, 1956), 28. Further parenthetical page references in the text will be to this work. His later formulation--"The primary religion of mankind arises chiefly from an anxious fear of future events" (65)--recalls Philo's pithy version, namely, "terror is the primary principle of religion" (Dialoguesconcerning Natural Religion, XII). ~Hume's "Inexplicable Mystery": His Views on Religion (Philadelphia, 199o), 9. Hereafter HIM. [5931 594 JOURNAL OF THE HISTORY OF PHILOSOPHY 33:4 OCTOBER 1995 In his account of the "propensity of human nature, which leads into a system, that gives them some satisfaction," Yandell admits that "no explanation is given of exactly what sort of satisfaction is in question," yet he goes on without a pause to speak of how "people accept different and various explanatory systems"; referring to a natural "propensity to understand," he concludes that "for Hume, we need not accept a religious system of explanation, but most of us in fact do so."s I suggest that Yandell's shift from "system" to "explanatory system," which is unheralded, is of crucial significance because the emphasis on explanation tends to call to a reader's mind just the sort of appeal which Hume decisively rejects. I shall argue that Hume draws our attention to and decisively excludes from his account a concept of explanation which actually does play an important role in other parallel accounts--namely, a concept which focuses on the integrity of a broad picture and an ultimate accounting; Hume points to such a concept in his references to the "frame of the universe," "final causes," and the "first rise of the visible system." Such a role might seem to elaborate Hume's appeal to common sense--after all, isn't the natural response to "unknown causes" to try to understand them, and isn't the attempt to understand them the same as looking for an "ultimate" explanation, however crude it might be at the outset? Although this might seem commonsensical to others (as we shall see), I want to argue that what Hume sees at work in the origin of religion is not a search for such an explanation, even a crude one. Rather, on Hume's view the only curiosity at work is a curiosity about how to cope: the propensity to a system is the propensity to the kind of determinacy which is expedient for control, and the only satisfaction the system provides is one in terms of a coping which is independent of truth-seeking...

Among the plethora of citations of different authors and genres that help to embellish Plutarch’s learned prose, passages by the choral poets Alcman, Stesichorus, Ibycus and Bacchylides make an interesting group, albeit far fewer than the citations of Pindar and Simonides, which have been dealt with extensively. This paper aims to highlight the modest but significant contribution Plutarch makes to the constitutio textus, reception history, and the very image of these important, but deficiently transmitted authors. At the same time, it (...) addresses the form of the quotations, their distribution and function in the Plutarchan corpus, and their possible sources, including the school. (shrink)

Palace of the End is a dense triptych of monologues exploring alternative narratives - albeit based in real facts - behind the events and the headlines surrounding the war in Iraq. Borrowing its title from the former royal palace where Saddam Hussein’s torture chamber was located, Thompson’s docudrama is structured as a chain of monologues telling three real-life stories set in the context of the war in Iraq. The play conveys three unconventional interpretations of the realities of war: that of (...) a young American soldier convicted for her misconduct at Abu Ghraib, the prison that stands as one of the most controversial symbols of the American-led Iraq invasion; a British scientist and weapons inspector who denounces what he understands as the false arguments given by his country’s leaders for engaging in a distant war; and an Iraqi mother whose life was shattered firstly by Saddam Hussein’s authoritarian regime, and later by the American first Gulf War. Each story is an enthralling and gut-wrenching reflection of one of the contemporary world’s most studied and controversial conflicts. The play gives voice to three different kinds of war victims, insofar as their political subjectivities and their moral conundrums are concerned. (shrink)

This book examines the significantly similar, yet finally different, thinking of two nineteenth-century existentialist thinkers, Soren Kierkegaard and Friedrich Nietzsche. Its focus is on the different ways each envisioned a joyful acceptance of life - a concern they shared. Each strove to give a place to this acceptance in his picture of life, but their conceptions of it are far apart.
