Categorial Intuition

Abstract At the beginning of Prolegomena zur Geschichte des Zeitbegriffs (Gesamtausgabe, volume 20), Heidegger extensively puts forward his views against phenomenology, especially that of Husserl, which is the one we are going to consider. By means of what he calls the “fundamental discoveries of phenomenology”, that is, intentionality, categorial intuition and the meaning of the a priori in Husserl’s Logical!nvestigations, Heidegger reaches a definition of phenomenology: “the analytic description of intentionality in its a priori”. Next, Heidegger proceeds to what he characterizes as an “ immanent critique” of phenomenology, that consists in highlighting that in Ideas Husserl does make but omits the fundamental question on “the being of consciousness” and on “the sense of being”, in a way that ends up in being un-phenomenological. We go into Heidegger’ S text in order to consider the legitimacy of its critique and, particularly, its alleged immanence.

A distinction must be made between the philosophical theory of conceptual analysis and the historical philosophical movement of Conceptual Analysis. The theory of conceptual analysis holds that concepts – general meanings of linguistic predicates – are the fundamental objects of philosophical inquiry, and that insights into conceptual contents are expressed in necessary ’conceptual truths’ (analytic propositions). There are two methods for obtaining these truths: - direct a priori definition of concepts; - indirect ’transcendental’ argumentation. The movement of Conceptual Analysis arose at Cambridge during the first half of the twentieth century, and flourished at Oxford and many American departments of philosophy in the 1950s and early 1960s. In the USA its doctrines came under heavy criticism, and its proponents were not able to respond effectively; by the end of the 1970s the movement was widely regarded as defunct. This reversal of fortunes can be traced primarily to the conjunction of several powerful objections: the attack on intensions and on the analytic/synthetic distinction; the paradox of analysis; the ‘scientific essentialist’ theory of propositions; and the critique of transcendental arguments. Nevertheless a closer examination indicates that each of these objections presupposes a covert appeal to concepts and conceptual truths. In the light of this dissonance between the conventional wisdom of the critics on the one hand, and the implicit commitments of their arguments on the other, there is a manifest need for a careful re-examination of conceptual analysis.

Pea is the most widely cultivated grain legume crop in Europe. In the French research project PeaMUST, a large public and private sector partnership has been set up to undertake complementary strategies towards the development of high and stable yielding cultivars. These different strategies will contribute to the definition of a pea ideotype based on both a priori and a posteriori approaches. On the one hand, genomic selection will identify interesting genotypes which may display new phenotypic ideotypes. On the other hand, marker-assisted selection will enable cumulating resistance for a given or different stresses to reach more durably stable phenotypes. Moreover, mutations identified in candidate genes controlling aerial and root architecture will be tested for their effects on stress tolerance.

In this work, a novel phenomenological model is proposed to study the liquid-to-solid phase change of eutectic and hypoeutectic alloy compositions. The objective is to enhance the prediction capabilities of the solidification models based on a-priori definition of the solid fraction as a function of the temperature field. However, the use of models defined at the metallurgical level is avoided to minimize the number of material parameters required. This is of great industrial interest because, on the one hand, the classical models are not able to predict recalescence and undercooling phenomena, and, on the other hand, the complexity as well as the experimental campaign necessary to feed most of the microstructure models available in the literature make their calibration difficult and very dependent on the chemical composition and the treatment of the melt. Contrarily, the proposed model allows for an easy calibration by means of few parameters. These parameters can be easily extracted from the temperature curves recorded at the hot spot of the quick cup test, typically used in the differential thermal analysis (DTA) for the quality control of the melt just before pouring. The accuracy of the numerical results is assessed by matching the temperature curves obtained via DTA of eutectic and hypoeutectic alloys. Moreover, the model is validated in more complex casting experiments where the temperature is measured at different thermocouple locations and the metallurgical features such as grain size and nucleation density are obtained from an exhaustive micrography campaign. The remarkable agreement with the experimental evidence validates the predicting capabilities of the proposed model.

This chapter discusses terrorism in the context of diplomacy. As far as diplomacy is concerned, attacks on diplomatic and consular missions and on diplomats are attacks on institutions which on the one hand enjoy inviolability under international law but on the other offer attractive targets simply because of their representative character. There can be no a priori definition of procedure to be applied if such attacks take place, although experience shows that capitulation leads only to an escalation in terrorist demands. The only way to work out any guidance on best practice is by taking examples and deducing from them such general advice as one can. Hence the chapter provides some case examples of destructive attacks on missions, the challenges on diplomacy with regards to terrorism, the suppression of terrorism, negotiations, and others.

Law, we are accustomed to say, comprises two elements. It is a body of obligatory rules of conduct, but it differs from other obligatory rules, such as moral precepts or the rules of a game, in that it is enforced by the state. On the one hand, law exists as a conceptual system of normative rules; on the other, it dwelis as well in the realm of brute fact, where it is something that is “done” or enforced by the state. But here surely is a snake swallowing its own tail, for the state which concretises law on the level of actuality is itself a creature of the realm of ideality: the state is meaningless except as a legal concept.What is needed is a treatment of law which will equate the actual practice of government with the conceptual system of rules that are obligatory, not merely upon citizens, but upon government as well. There seem to be good a priori reasons for believing that this cannot be done, and for believing, furthermore, that no definition of law in terms of either of the elements alone will be satisfactory.The American writers loosely grouped as “realistic” have made a thoroughgoing effort to solve the problem by omitting the normative element. With individual variations, these authors have argued that law is simply the behavior of the judge. Since the judge is a man, the law which he makes is a by-product of his personal existence, secreted, perhaps, as a result of a bad breakfast, as a pearl is secreted by an oyster. It is meaningless to talk of law as obligatory, or law as rule. Law is occurrence, on the simple level of fact, and it is not to be discussed in terms of obligation or validity, ideas which are the product of folklore or father-fixation.

Abstract. The article discusses the emergence of a functional literacy construct and the rediscovery of illiteracy in industrialized countries during the second half of the 20th century. It offers a short explanation of how the construct evolved over time. In addition, it explores how functional (il)literacy is conceived differently by research discourses of cognitive and neural studies, on the one hand, and by prescriptive and normative international policy documents and adult education, on the other hand. Furthermore, it analyses how literacy skills surveys such as the Level One Study (leo.) or the PIAAC may help to bridge the gap between cognitive and more practical and educational approaches to literacy, the goal being to place the functional illiteracy (FI) construct within its existing scale levels. It also sheds more light on the way in which FI can be perceived in terms of different cognitive processes and underlying components of reading. By building on the previous work of other authors and previous definitions, the article brings together different views of FI and offers a perspective for a needed operational definition of the concept, which would be an appropriate reference point for future educational, political, and scientific utilization.

This book is an examination of Britain as a democratic society; what it means to describe it as such; and how we can attempt such an examination. The book does this via a number of ‘case-studies’ which approach the subject in different ways: J.M. Keynes and his analysis of British social structures; the political career of Harold Nicolson and his understanding of democratic politics; the novels of A.J. Cronin, especially The Citadel, and what they tell us about the definition of democracy in the interwar years. The book also investigates the evolution of the British party political system until the present day and attempts to suggest why it has become so apparently unstable. There are also two chapters on sport as representative of the British social system as a whole as well as the ways in which the British influenced the sporting systems of other countries. The book has a marked comparative theme, including one chapter which compares British and Australian political cultures and which shows British democracy in a somewhat different light from the one usually shone on it. The concluding chapter brings together the overall argument.

And Control

In this paper, Linear Quadratic (LQ) optimal control concepts are applied for the active control of vibrations in helicopters. The study is based on an identified dynamic model of the rotor. The vibration effect is captured by suitably augmenting the state vector of the rotor model. Then, Kalman filtering concepts can be used to obtain a real-time estimate of the vibration, which is then fed back to form a suitable compensation signal. This design rationale is derived here starting from a rigorous problem position in an optimal control context. Among other things, this calls for a suitable definition of the performance index, of nonstandard type. The application of these ideas to a test helicopter, by means of computer simulations, shows good performances both in terms of disturbance rejection effectiveness and control effort limitation. The performance of the obtained controller is compared with the one achievable by the so called Higher Harmonic Control (HHC) approach, well known within the helicopter community.

AbstractChronic lung infections are among the most diffused human infections, being often associated with multidrug-resistant bacteria. In this framework, the European project “Light4Lungs” aims at synthesizing and testing an inhalable light source to control lung infections by antimicrobial photoinactivation (aPDI), addressing endogenous photosensitizers only (porphyrins) in the representative case of S. aureus and P. aeruginosa. In the search for the best emission characteristics for the aerosolized light source, this work defines and calculates the photo-killing action spectrum for lung aPDI in the exemplary case of cystic fibrosis. This was obtained by applying a semi-theoretical modelling with Monte Carlo simulations, according to previously published methodology related to stomach infections and applied to the infected trachea, bronchi, bronchioles and alveoli. In each of these regions, the two low and high oxygen concentration cases were considered to account for the variability of in vivo conditions, together with the presence of endogenous porphyrins and other relevant absorbers/diffusers inside the illuminated biofilm/mucous layer. Furthermore, an a priori method to obtain the “best illumination wavelengths” was defined, starting from maximizing porphyrin and light absorption at any depth. The obtained action spectrum is peaked at 394 nm and mostly follows porphyrin extinction coefficient behavior. This is confirmed by the results from the best illumination wavelengths, which reinforces the robustness of our approach. These results can offer important indications for the synthesis of the aerosolized light source and definition of its most effective emission spectrum, suggesting a flexible platform to be considered in further applications.

Abstract We extend the recently developed Yangian bootstrap for Feynman integrals to Minkowski space, focusing on the case of the one-loop box integral. The space of Yangian invariants is spanned by the Bloch-Wigner function and its discontinuities. Using only input from symmetries, we constrain the functional form of the box integral in all 64 kinematic regions up to twelve (out of a priori 256) undetermined constants. These need to be fixed by other means. We do this explicitly, employing two alternative methods. This results in a novel compact formula for the box integral valid in all kinematic regions of Minkowski space.
