Recently published structural analysis and galvanomagnetic studies of a large number of different bulk and mesoscopic graphite samples of high quality and purity reveal that the common picture assuming graphite samples as a semimetal with a homogeneous carrier density of conduction electrons is misleading. These new studies indicate that the main electrical conduction path occurs within 2D interfaces embedded in semiconducting Bernal and/or rhombohedral stacking regions. This new knowledge incites us to revise experimentally and theoretically the diamagnetism of graphite samples. We found that the c-axis susceptibility of highly pure oriented graphite samples is not really constant, but can vary several tens of percent for bulk samples with thickness t ≳ 30 μ m, whereas by a much larger factor for samples with a smaller thickness. The observed decrease of the susceptibility with sample thickness qualitatively resembles the one reported for the electrical conductivity and indicates that the main part of the c-axis diamagnetic signal is not intrinsic to the ideal graphite structure, but it is due to the highly conducting 2D interfaces. The interpretation of the main diamagnetic signal of graphite agrees with the reported description of its galvanomagnetic properties and provides a hint to understand some magnetic peculiarities of thin graphite samples.

These new studies indicate that the main electrical conduction path occurs within 2D interfaces embedded in semiconducting Bernal and/or rhombohedral stacking regions. This new knowledge incites us to revise experimentally and theoretically the diamagnetism of graphite samples. We found that the $c$-axis susceptibility of highly pure oriented graphite samples is not really constant but can vary several tens of percent for bulk samples with thickness $t \gtrsim 30~\mu$m, whereas by a much larger factor for samples with smaller thickness. The observed decrease of the susceptibility with sample thickness resembles qualitatively the one reported for the electrical conductivity and indicates that the main part of the $c-$axis diamagnetic signal is not intrinsic of the ideal graphite structure but it is due to the highly conducting 2D interfaces.

Sugar is one of the most important elements in human nutrition. The Common Market Organisation for sugar has been a subject of considerable debate since its establishment in 1968. The European agricultural market has been criticized for its heavy regulations and subsidization. The sugar market is one of the most regulated ones; however, this will change radically in 2017 when the current system of production quotas will end. The current EU sugar market changed is structure during the last several decades. The significant number of companies left the market and EU internal sugar market became more concentrated. The aim of this paper is presentation characteristics of sugar market with respect to the supposed market failure – reduction in competition. The analysis also identifies the main drivers and determinants of the EU especially quota sugar market. In relation to paper’s aim the following results are important. The present conditions of the European sugar market have led to market failure when nearly 75 % (10 million tonnes) of the quota is controlled by five multinational companies only. These multinational alliances (especially German and French one) are also taking control over the production capacities of their subsidiaries. In most countries, this causes serious problems as the given quota is controlled by one or two producers only. This is a significant indicator of market imperfection. The quota system cannot overcome the problem of production quotas on the one hand and the demand on the other; furthermore, it also leads to economic inefficiency. The current EU sugar market is under the control of only Sudzucker, Nordzucker, Pfeifer and Langen, Tereos and ABF.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

Muslim Culture

The typology of rationality is one of major issues of modern philosophy. In an attempt to provide a typology to Oriental materials, a researcher faces additional problems. The diversity of the Orient as such poses a major challenge. When we say “Oriental,” we mean several cultures for which we cannot find a common denominator. The concept of “Orient” involves Arabic, Indian, Chinese, Turkish and other cultures, and the only thing they share is that they are “non-Western.” Moreover, even if we focus just on Islamic culture and look into rationality in this context, we have to deal with a conglomerate of various trends, which does not let us define, with full confidence, a common theoretical basis and treat them as a unity. Nevertheless, we have to go on trying to find common directions in thought development, so as to draw conclusions about types of rationality possible in Islamic culture. A basis for such a typology of rationality in the context of the Islamic world was recently suggested in A.V. Smirnov’s logic of sense theory. However, actual empiric material cannot always fit theoretical models, and the cases that do not fit the common scheme are interesting per se. On the one hand, examination of such cases gives an opportunity to specify certain provisions of the theory and, on the other hand, to define the limits of its applicability.

This chapter reviews the books Fútbol, Jews and the Making of Argentina (2014), by Raanan Rein, translated by Marsha Grenzeback, and Muscling in on New Worlds: Jews, Sport, and the Making of the Americas (2014), edited by Raanan Rein and David M.K. Sheinin. Rein’s book deals with the “making” of Argentina through football (soccer), while Muscling in on New Worlds focuses on the “making” of the Americas (mainly the one America, called the United States) through sports. Muscling in on New Worlds is a collection of essays that seeks to advance the common theme of sport as “an avenue by which Jews threaded the needle of asserting a Jewish identity.” Topics include Jews as boxers, Jews and football, Jews and yoga, Orthodox Jewish athletes, and American Jews and baseball. There are also essays about the cinematic and literary representations of Jews in sports.

The Ideal

This chapter argues that academic freedom is justified because it is an inherently epistemic practice that serves the ideals of democracy. With Dewey, it is argued that “The one thing that is inherent and essential [to the idea of a university] is the ideal of truth.” But far from being apolitical, the value of pursuing truth and knowledge—the value that justifies academic freedom, both within and without the public mind—is a fundamental democratic value, and for three reasons: the practices of academic inquiry exemplify rational inquiry of the kind needed for democratic deliberation; those practices serve to train students to pursue that kind of inquiry; and those practices are important engines of democratic dissent.

Religious Differences

This chapter considers a series of formative debates in British anthropology from the 1840s through the 1860s and uses them to map out the two dominant constructions of religion whose politics the subsequent authors in this study would reinvent. It describes, on the one hand, a liberal and evangelical construction of religion as the common human capacity for spiritual cultivation, and on the other hand a conservative, reactionary model that interpreted religious differences as the expressions of fixed racial identities that neither civilization nor Christianization could erase. In the work of the Oxford philologist F. Max Müller we see how the former model tended to associate religion above all with language. But we can also see the subtle forms of determinism that it contained—an ambiguity that Arnold, Pater, Eliot, and Lang would explore by picturing racialized religion as a resource for liberal self-cultivation.

The Ideal

The introduction ‘Philhellenism and Theatromania’ retraces the emergence of these two phenomena in the German middle class. The year 1755 marks a watershed in this regard: it saw the publication of J. J. Winckelmann’s treatise Reflections on the Painting and Sculpture of the Greeks and the premiere of G. E. Lessing’s first domestic tragedy Miß Sara Sampson. Both share the common root and motivation once and for all to banish Frenchified German court culture. While Winckelmann’s treatise praised the ‘noble simplicity’ and ‘quiet greatness’ of the Greek masterpieces, Lessing’s play advocated new family values and the ideal of ‘naturalness’ as the true virtues of the middle class. The merging of Philhellenism as the cult of beauty with theatromania as the quest for identifying in a social group and as an individual provided the basic condition for staging Greek tragedies.

The Ideal

Every legal system that ties judicial decision making to a body of preconceived norms has to face the tension between the normative formulation of the ideal and its approximation in social reality. In the parlance of the common law, it is, more concretely, the remedy that bridges the gap between the ideal and the real, or, rather, between norms and facts. In the common law world—particularly in the United Kingdom and the Commonwealth—a lively discourse has developed around the question of how rights relate to remedies. To the civilian legal scholar—used to thinking within a framework that strictly categorizes terms like substance and procedure, subjective right, action, and execution—the concept of remedy remains a mystery. The lack of “remedy” in the vocabulary of the civil law is more than just a matter of attaching different labels to functional equivalents, it is the expression of a different way of thinking about law. Only if a legal system is capable of satisfactorily transposing the abstract discourse of the law into social reality does the legal machinery fulfill its purpose: due to the pivotal importance of this translational process, the way it is cast in legal concepts thus allows for an insight into the deep structure of a legal culture, and, convergence notwithstanding, the remaining epistemological differences between the legal traditions of the West. A mixed jurisdiction must reflect upon these differences in order to understand its own condition and to define its future course.
