We study mechanisms leading to wealth condensation. As a natural starting point, our model adopts a neoclassical point of view, i.e., we completely ignore work, production, and productive relations, and focus only on bilateral link between two randomly selected agents. We propose a simple matching process with deterministic trading rules and random selection of trading agents. Furthermore, we also neglect the internal characteristic of traded goods and analyse only the relative wealth changes of each agent. This is often the case in financial markets, where a traded good is money itself in various forms and various maturities. We assume that agents trade according to the rules of utility and decision theories. Agents possess incomplete knowledge about market conditions, but the market is in equilibrium. We show that these relatively frugal assumptions naturally lead to a wealth condensation. Moreover, we discuss the role of wealth redistribution in such a model.

The article looks at book production and circulation from the point of view of translators, who, as purchasers and readers of foreign-language books, are an important mediating force in the selection of literature for translation. Taking the German publisher Tauchnitz's series ‘Collection of British Authors’ and its circulation in Finland in the nineteenth and early twentieth century as a case in point, the article argues that the increased availability of English-language books facilitated the acquiring and honing of translators' language skills and gradually diminished the need for indirect translating. Book history and translation studies meet here in an examination of the role of the Collection in Finnish translators' work.

Background:: Leishmaniosis is a neglected tropical disease and glyceraldehyde 3- phosphate dehydrogenase (GAPDH) is a key enzyme in the design of new drugs to fight this disease. Objective:: The present study aimed to evaluate potential inhibitors of GAPDH enzyme found in Leishmania mexicana (L. mexicana). Methods: A search for novel antileishmanial molecules was carried out based on similarities from the pharmacophoric point of view related to the binding site of the crystallographic enzyme using the ZINCPharmer server. The molecules selected in this screening were subjected to molecular docking and molecular dynamics simulations. Results:: Consensual analysis of the docking energy values was performed, resulting in the selection of ten compounds. These ligand-receptor complexes were visually inspected in order to analyze the main interactions and subjected to toxicophoric evaluation, culminating in the selection of three compounds, which were subsequently submitted to molecular dynamics simulations. The docking results showed that the selected compounds interacted with GAPDH from L. mexicana, especially by hydrogen bonds with Cys166, Arg249, His194, Thr167, and Thr226. From the results obtained from molecular dynamics, it was observed that one of the loop regions, corresponding to the residues 195-222, can be related to the fitting of the substrate at the binding site, assisting in the positioning and the molecular recognition via residues responsible for the catalytic activity. Conclusion:: he use of molecular modeling techniques enabled the identification of promising compounds as inhibitors of the GAPDH enzyme from L. mexicana, and the results obtained here can serve as a starting point to design new and more effective compounds than those currently available.

In this article, from a multidisciplinary point of view, key questions were raised that defined how the bloc of communist countries had an impact on the International Labor Organization. The author believes that the role of communist countries in the ILO depended not only on the international political, economic and social context of the time, but also on the field of globalized labor history and relations of international organizations. The starting point of this article is the central hypothesis that the concept of protecting employees and the rights of employers has always been presented from the point of view of the „bloc” of capitalist states, without reference to the role of communist states.

The interest in Presocratic philosophy, and the scholarly output on it, have been rising again in the last few years. I start this review with a sample of recent publications in the area. It is easy to expect that Daniel Graham's collection of The Texts of Early Greek Philosophy, in two volumes, will become a popular tool for the study of Presocratic philosophy (for some qualifications on this expectation see below). The sourcebook aims to present ‘the complete fragments and a generous selection of testimonies’ for the major early Greek philosophers. English translations (all by Graham himself) are set opposite to Greek and Latin texts (with slim textual notes identifying substantive textual variants), with succinct introductions for each philosopher, and brief commentaries and basic bibliographies following the texts. The Diels-Kranz (hereafter DK) collection is the starting point for this sourcebook, but Graham is quite selective in his shortlist of those who deserve a place in his sourcebook: out of ninety DK sections, he includes only nineteen philosophers (Thales, Anaximander, Anaximenes, Xenophanes, Heraclitus, Parmenides, Zeno of Elea, Anaxagoras, Empedocles, Diogenes of Apollonia, Melissus, Philolaus, Leucippus, Democritus, Protagoras, Gorgias, Antiphon, Prodicus, and Pythagoras, the last being relegated to an appendix) and two anonymous texts, the Anonymus Iamblichi and the Dissoi Logoi. Although the sourcebook includes some fragments and testimonies that did not appear in DK (e.g. the Strasbourg papyrus for Empedocles), and only a selection of the testimonies included there, the major difference in terms of the material included for the selected philosophers is the order in which fragments and testimonies are presented. The fragments are incorporated within the context of the broader testimonies containing them (and signalled in bold), rather than listed separately, as in DK; the numbering of fragments and testimonies does not correspond to DK, but the DK numbers are given in addition, and volume 2 includes a list of concordances (besides an index of sources, an index of other passages quoted by Graham in his end-of-chapter commentaries, and a short general index of names and topics). Graham's choice is definitely a healthy step forward from DK's largely artificial strategy of separating fragments and testimonies into two different sections; one might wonder whether the decision to signal in bold words, phrases, sentences, and sections that supposedly count as original fragments within the broader context in which they occur is still too heavily indebted to the DK model. For each author the texts are organized in four main sections: life, works, philosophy, and reception, with the philosophy section typically structured into thematic subsections. Of course the strengths and shortcomings of a monumental work such as Graham's can be fully appreciated only over time, once you use it repeatedly in your teaching and research. I have mentioned Graham's approach to the distinction between fragments and testimonies: some sustained methodological discussion, and explanation of the criteria guiding the distinction, would have been welcome. Unavoidably some readers will find Graham's shortlist of philosophers and selection of texts unsatisfactory and too narrow: some qualms about notable exclusions – such as Solon, Alcmaeon, Archytas, Pherecydes, the Orphics, and the Derveni author – have already been voiced (for example, by Jason Rheins in his review in Notre Dame Philosophical Reviews). As far as I could see, the translations are reliable, and the short introductions, commentaries, and bibliographies provide just enough information for readers to contextualize the authors and texts within the philosophical tradition (less so within the broader archaic Greek cultural and literary tradition), and appreciate some of the key exegetical and philosophical issues that they raise. Just enough, and this brings me to what I find to be the less convincing aspect of such an enterprise as Graham's. His collection will certainly be of some use as an accessible reference tool for advanced students and researchers, but its selectivity will prevent it from becoming a research tool in its own right, and standard editions of individual Presocratics will remain the first port of call (for example, the second edition of Coxon's The Fragments of Parmenides, reviewed below). At the same time, the breadth of the material that it contains, coupled with the relative thinness of the apparatus of introductions and commentaries, does not make The Texts of Early Greek Philosophy the kind of introductory sourcebook that could be used on its own in an introductory undergraduate course on ancient philosophy, or on the Presocratics. It is difficult to imagine lecturers of such courses prescribing to their students more than a small fraction of the material offered by Graham; and those students will still need to use standard introductions to Presocratic philosophy such as Kirk–Raven–Schofield, Barnes, McKirahan, or Warren to make real sense of the evidence presented by Graham, placing it within a unified narrative about the nature and development of early Greek philosophy. From this point of view, Graham's collection risks falling into no man's land from the point of view of its readership: it is neither a ground-breaking, research-shaping tool such as, for example, Long and Sedley's collection on The Hellenistic Philosophers has been for three decades now, nor an introductory textbook easily accessible (for both sheer bulk and price) to undergraduate students. That said, Graham's work still deserves a place in all university libraries and on the shelves of ancient philosophy scholars.

From a thermodynamic point of view, living cell life is no more than a cyclic process. It starts with the newly separated daughter cells and restarts when the next generations grow as free entities. In this cycle the cell changes its entropy. In cancer the growth control is damaged. In this paper we analyze the role of the volume-area ratio in cell in relation to the heat exchange between cell and its environment in order to point out the effect on the cancer growth. The result holds to a possible control of the cancer growth based on the heat exchanged by the cancer towards its environment, and the membrane potential variation, with the consequence of controlling the ions fluxes and the related biochemical reactions. This second law approach could represent a starting point for a possible future support for the anticancer therapies, in order to improve their effectiveness for the untreatable cancers.

Emotions are human things. When people consider emotions from a strategic leadership point of view, additional individual framing factors become unavoidable and play a role in an organization's management process. This research aimed to evaluate the existing literature on emotion and strategic leadership comprehensively. The study was a survey of the literature on emotion and strategic leadership. Because of the search and exclusion criteria applied, only 24 articles were relevant. The texts were studied using the grounded theory method to build a new theoretical model and identify essential characteristics of organizational emotion shifting. The model tried to demonstrate how the interaction of human and organizational elements and the task and problems faced by strategic leaders result in internal and external emotional shifts. This literature survey and theoretical integration provided a starting point for further research. The results show that the conceptualization of emotions in strategic leadership encompasses all five levels: positive emotions, negative emotions, emotional empowerment (internal emotion shaping), the establishment of external resources, and the use of power (external emotions shaping). The research revealed that emotion in organizational shaping was a key variable. This variable identified the numerous ways strategic leaders use emotion to shape organizations. It indicates that the concept can bring the person (strategic leader) and organizational levels together. In light of the limited literature, mainly focusing on strategic and emotional leadership, the model should be tested as a foundation for future research.

AbstractThe concept ofmanipulative abductionis devoted to capture the role of action in many interesting cognitive situations: action provides otherwise unavailable information that enables the agent to solve problems by starting and performing a suitable abductive process of generation or selection of hypotheses. We observe that many external things, usually inert from an epistemological point of view, can be transformed intoepistemic mediators. I will present some details derived from the history of the discovery of the non-Euclidean geometries that illustrate the relationships between strategies for anomaly resolution and visual thinking. Geometrical diagrams are external representations that play both amirrorrole (to externalize rough mental models) and anunveilingrole (as gateways to imaginary entities). I describe them as epistemic mediators able to perform various explanatory, non-explanatory, and instrumental abductive tasks (discovery of new properties or new propositions/hypotheses, provision of suitable sequences of models as able to convincingly verifying theorems, etc.). I am also convinced that they can be exploited and studied in everyday non-mathematical applications also to the aim of promoting new trends in artificial intelligence modeling of various aspects of hypothetical reasoning: finding routes, road signs, buildings maps, for example, in connection with various zooming effects of spatial reasoning. I also think that the cognitive activities of optical, mirror, and unveiling diagrams can be studied in other areas of manipulative and model-based reasoning, such as the ones involving creative, analogical, and spatial inferences, both in science and everyday situations so that this can extend the epistemological, computational, and the psychological theory.

How might a singular object, a herdsman’s lasso known as the ‘ uurga’, facilitate a fresh understanding of cosmology and human–animal relationships in nomadic Mongolia? ‘ Uurga shig’ re-evaluates the performance of an object as an agentive social participant and the role of drawing as an anthropologically relevant method, outlining the need for interdisciplinary exchange between the fields of participatory art and anthropology. With a starting point of Alfred Gell’s thesis of ‘Traps as artworks and artworks as traps’ (1996), the lasso presents an alternative point of view to the western ‘zoological framing’ criticized by Massumi (‘What animals teach us about politics’, 2014). Instead the uurga functions as a non-Euclidean drawing tool, a frame through which to better understand the fluid relationships underpinning human–animal codependency on the Mongolian steppe. From the line on a page to the ‘drawing through’ of a thread in a needle and the ‘drawing in’ of a wild horse in nomadic Mongolia, the author explores the application of drawing as an intimate method for analyzing moving relationships. With a focus on the drawn line as a connecting device that lends itself to figure–ground reversal, she extends the application of drawing as a prosthetic technology, one that might be used to catalyze a perspectival shift into the worlds of other animals.

The present article is connected in terms of its topic with the text entitled Harpsichord or piano? Different concepts in the 18th century keyboard music published by the author in “Notes Muzyczny” no. 1 (9) 2018, and it is the continuation of the discussion on the capacities and ways of performance of music from the Classical period, which is now understood as piano music, on the harpsichord. Subsequent parts will touch on peculiar performance topics connected with the role of the harpsichord in that period: the understanding and rendering of the dynamics, the performance of arpeggios, and the ornamentation. The starting point of the author’s deliberations is the textbook by Daniel Gottlob Türk entitled Klavierschule oder Anweisung zum Klavierspielen für Lehrer und Lernende mit kritischen Anmerkungen. (Leipzig, Halle 1789) and textbooks by other theoreticians of that period (J. J. Quantz, C. Ph. E. Bach), as well as modern publications (F. Neumann, C. Brown, S. Rampe, J. Trinkewitz). The possibility of the rendering of the dynamics understood as the capacity to influence the strength of single sounds is not the necessary condition for performing keyboard compositions from the second half of the 18th century. Neither is it the feature placing keyboard instruments in any particular hierarchy of values. In the 18th century sources it is hard to find any opinions stating that harpsichords were perceived as worse than other keyboard instruments due to the impossibility of shaping the dynamics of individual sounds. The most significant remarks referring to the performance are the topics connected with expression. The dynamics is not the only mean thanks to which a performance becomes expressive. It is possible to play in an expressive way on the harpsichord, yet it is achieved thanks to articulatory measures, agogic nuances, the right way of hitting keys and the proper selection of texture while playing basso continuo.

The trust account is one of the most commonly used legal tools in business and is the subject of numerous legal disputes. Due to the absence of a trust code, there are no uniform legal rules for the requirements of the trust account. Moreover, the protection of the trust accounts from creditors of the trustee and the settlor in compulsory enforcement and bankruptcy is unregulated. This thesis attempts to close the gap. First, the topic will be outlined on the basis of two rulings of the UK Supreme Court and the German Federal Court of Justice (BGH). Subsequently the rules set out in the German case law will be systematically analysed. The asset partitioning approach will then be chosen as the dogmatic starting point for the justification of the protective effect of the trust account. The trust will accordingly be qualified as a legal form for special patrimony, and the theory of special patrimony will be examined in depth. The crucial role of subjective and objective ringfencing in order to effect a partitioning of assets will be highlighted, and the rules in the jurisprudence critically evaluated from this point of view. The last chapter is a comparative presentation of Chinese trust law.
