Ludwig Wittgenstein was born in Vienna in 1889 and died in Cambridge in 1951. He studied engineering, first in Berlin and then in Manchester, and he soon began to ask himself philosophical questions about the foundations of mathematics. What are numbers? What sort of truth does a mathematical equation possess? What is the force of proof in pure mathematics? In order to find the answers to such questions, he went to Cambridge in 1911 to work with Russell, who had just (...) produced in collaboration with Whitehead (1861-1947) Principia Mathematica (1910-1913), a monumental treatise which bases mathematics on logic. But on what is logic based? Wittgenstein's attempt to answer this question convinced Russell that he was a genius. During the 1914-8 war he served in the Austrian army and in spare moments continued the work on the foundations of logic which he had begun in 1912. His war-time journal, Notebook s 1914-16 (1961), reveals the development of his ideas more clearly that the final version, Tractatus Logico- Philosophicus, which he published in the early 1920s.

With the growth of Muslim economies, both at the national and international levels, the issue of riba (interest, usury) poses great difficulties. The charging or receiving of riba has been forbidden in Islam, which presents a major problem to financial institutions that charge interest. Muslim legal scholars belonging to all schools of legal thought have reinterpreted scriptural sources to accommodate drastic economic changes; practical considerations have forced Muslim groups, both of Sunni and Shi'ite persuasion, to justify interest-based banking and other (...) institutions of finance. As a matter of religion, the status of interest is far from resolved. However, within the legal tradition, there are ethical principles like maslahah (public good) and la darar wa la dirar (no harm, no harassment) that will determine the future direction of a Muslim search for a morally responsible economy.

Local supplier corporate social responsibility in developing countries represents a powerful tool to improve labour conditions. This paper pursues an inter-organizational network approach to the global value chain literature to understand the influence of suppliers’ collective behaviour on their CSR engagement. This exploratory study of 30 export-oriented and first-tier apparel suppliers in Bangladesh, a developing country, makes three relevant contributions to GVC scholarship. First, we show that suppliers are interlinked in a horizontal network that restricts unilateral CSR engagement. This is (...) justified in that unilateral CSR engagement is a source of heterogeneity in labour practices; consequently, it triggers worker unrest. Second, we present and discuss an exploratory framework based on four scenarios of how suppliers currently engage in CSR given their network’s pressure toward collective behaviour: unofficial CSR engagement, geographic isolation, size and competitive differentiation, and external pressure. Finally, we show the need to spread CSR homogeneously among suppliers and to reconceptualize the meaning of CSR in developing countries, encouraging more scrutiny toward horizontal dynamics.

Introduction and discussion of a new German edition of the Bellicorum Instrumentorum Libri cum figuris et fictitijs literis conscriptus, Monaco di Baviera, Bayerische Staatsbibliothek, Cod. Icon. 242. This manuscript is the machine book of Giovanni Fontana. Fontana describes siege engines and inventions such as a magic lantern and a rocket-propelled device.

A finished sketch for a light-and-shadow projection device by the Paduan mechanical artisan Johannes de Fontana (c.1395–1455), in his manuscript book of drawings now known as Liber Bellicorum Instrumentorum, depicts a machine for communicating ideas or information through spectacle. The manuscript is fairly well known, and this sketch is just one of many interesting images worthy of study in its 70 leaves. A couple dozen manuscripts of the mechanical arts from this period survive, the best-studied of which fall into (...) the “Sienese school” and the “German school.” Fontana falls outside these, for he had far less influence than the Sienese. His work also is too early, it seems, to count in narratives directed toward the flowering of technological illustration in the sixteenth century. Of his images of subjects other than hydraulic and military machines only one deep study has been made, concerning two of the automata, although the present sketch has lately attracted a glance or two. Historians of technology pay scant attention to the first half of the fifteenth century, five decades that seem merely to repeat medieval knowledge and have the disadvantage to their prestige of falling “before Leonardo.” Whether one views Fontana as an engineer or as a science fiction illustrator, a great deal in the manuscript has not been given its due. The brief normative account in the literature so far on Fontana focuses on politics and warfare. My account in the case of his castellus image in this paper emphasizes issues of imagery, communication, subjectivity, moral feeling, spiritual life, and personhood. This account runs along two lines. For the first, I will suggest some untried ideas for approaching this image. In part this is in pursuit of what Jonathan Sawday calls the imaginative history of machines and mechanisms, though more largely it concerns contributing to a broad-range history of communication and persuasion. If we look at the image from our standpoint in aworld accustomed to the reproduction of images, we readily see in it an early step toward our present control of the display and diffusion of images. Fontana’s castle of shadows(castellus umbrarum), based on a worldwide transfer of technical knowledge about imagery in antiquity (and even in pre-history), presents some of the continuing questions driving thereproduction of imagery and the dispersal of information. As a practical matter, a sense ofproximity to Fontana and his time, as opposed to a sense of untranslatable distance, helps to broaden the historiography. My second line of thought is to oppose my account of Fontana’s’s castellus to an interpretation, and to the thinking behind it, that has started to appear on the borders of disciplinary history. This other interpretation reflects an increasingly influential approach to the history of technology and cultural theory that employs a growing and powerful line of philosophical thought. In 2003 Philippe Codognet, a philosopher of technology, published an essay in which he described Fontana’s castle of shadows as a specimen of the pre-historyof virtual reality devices. His reference of the castle of shadows is a bit casual, perhaps accidental in feeling; but it has begun to stimulate interest in Fontana’s striking idea and hasgiven it a bit of renown. Codognet’s view (along with his reproduction of the image) has been picked up by thinkers who are concerned with post-humanistic ideas derived from philosophical work in which the distinction between human persons and objects is deflated in such a way that both persons and objects are correctly characterized by attributes commonly divided into subjective and objective. What’s more, they are characterized by attributes that, under this view, are incorrectly distinguished from one another as the human, the organic, and the inorganic. The ontology supporting this approach denies the privileged epistemological relationship of humans to the world. This school of thought is object-oriented ontology, also known in a more radical form as speculative realism. Its potential influence on historiography is great, and part of it is and will be valuable. Its current actual influence is centered on medieval cultural studies and on the history of technology.

The next origin of the generation of the 98 is inserted in the complex Spanish sociocultural panorama in the end of XIX century. "Regeneracionisme", regionalisme, the social and religious questions, the war against the U.S.A., the loss of Cuba, Puerto Rico and the Philippines, to more of the political crisis of the Restoration, are the circumstances to consider.

ABSTRACT This article draws attention to the reception that François Fénelon's Télémaque received in England in the first half of the eighteenth century. It overturns the historiographical assumption that the Jacobites were the leading disseminators of this continental bestseller on the other side of the Channel. Even though in the English intellectual context Télémaque's framework was unorthodox, many staunch supporters of the Glorious Revolution were fascinated by the book's portrayal of a virtuous king who respects laws, rights and liberties, and (...) sacrifices himself to improve the wellbeing of his subjects. Moderate Whigs - who included several Huguenot refugees - capitalised on the poem's esprit du roi in order both to celebrate the English kings and to construct the ‘Myth of Louis XIV' as an example of how a sovereign should not rule. The study of the book's reception thus presents a somewhat emblematic case study from which to view the genesis of ‘Englishness', that of an ideological discourse largely based on a process of overturning. In addition, the Télémaque responded to the thirst for ‘useful Knowledge' that distinguished the advocates of ‘politeness' and, not least, its mild pedagogical approach rendered it a precious resource for the ‘moderation’ of the youth.

Leibniz was writing his "Discourse on the Natural Theology of the Chinese" as the Leibniz-Clarke Controversy developed. Both were terminated by his death. These two fronts show interesting doctrinal correlations. The first is Leibniz' concern for the "decadence of natural religion." The dispute with Clarke began with it, and the Discourse is a defense of Chinese natural religion in order to show its agreement with Christian natural religion. The Controversy can be summed up as "clockmaker God versus idle God." Leibniz (...) wants to escape from the perverse consequences that all criticism of divine voluntarism seems to cause. Thus, his elaboration is directed at a distinct concept of a God that rules without interposing, a supramundane intelligence. And the Leibnizian interpretation of the natural theology of the Chinese can be viewed the same way: it emphasizes a First Principle, Li, which rules without interposing. (shrink)

In a hydrocarbon exploration workflow, marine controlled-source electromagnetic data are usually acquired after seismic interpretation for prospect identification and close-to-the-drilling decision making. Therefore, the mCSEM interpreter must provide quick answers to the asset teams in a way that the EM interpretation can add value to that decision. To achieve that goal, Petrobras developed a fast-track mCSEM interpretation workflow that consists in identifying anomalies in the mCSEM data set by frequency normalization, and then performing 1D CMP inversions followed by 2.5D polygonal (...) inversions. The proposed workflow was successfully applied to several mCSEM surveys offshore Brazil. We evaluated an application in a complex geologic setting where the reservoir dips toward allochthonous salt. The reservoir appears as a flat spot in the seismic section, but with no significant amplitude variation with offset response. The mCSEM analysis confirmed the seismic anomaly and extended it northward. Two drilled wells corroborated the mCSEM interpretation. (shrink)

À partir d’une analyse de la matérialité linguistique, cet article explore les processus de subjectivation et d’identification qui constituent le(s) sujet(s) des différentes pratiques urbaines, par rapport à l’espace de la rue et dans le cadre de disputes visant à l’affirmation d’identités socialement légitimées. Le corpus constitué pour ma recherche est de nature hétérogène, aussi bien dans sa matérialité symbolique que du point de vue de son inscription institutionnelle et de sa circulation sociale.

This essay examines the place of Sallust in Machiavelli's political theory. Such an examination is necessary and fruitful for two basic reasons. First, the interpretative and secondary literature on Machiavelli's classical sources has neglected, with very few exceptions, the influence and role Sallust may have played in the formulation of Machiavelli's thinking. Second, the essay argues that Sallust is important to Machiavelli's attempt to recover republican liberty. At the core of Machiavelli's project to discover 'new modes and orders' is the (...) fundamental Roman republican antithesis between libertas and dominatio. The very critique of dominatio presupposes a conception of libertas without which such a critique would be impossible. Sallust is a useful source for Machiavelli's inquiry into the political, social and military determinants foRA vivere libero e civile. Elements of such a political life are prefigured in Sallust's conception of republican politics, where 'cives cum civibus de virtute certabant' -- that is, where robust competition and healthy conflict express the virtus and the bonae artes of the body politic. In effect, Sallust is important to Machiavelli both as a historian who provides a useful critique of monarchy and despotism, and as a source through which Machiavelli is able to develop his conception of politics in general, and of republican politics in particular.
