Abstract The paper deals with the study of the reaction positions of the support surface on the vehicle wheels. The problems is that the longitudinal drifts of the normal reaction are not fully described. There is no initial data on the rolling radii in the presence of a moment on the wheel. The existing problem does not allow considering components of the longitudinal drifts of normal reactions. The authors noted that the accuracy of predicting the stability and controllability of the vehicle deteriorates. The way out of this is to search other ways to determine the values of these drifts. In conclusion, the authors admitted dividing the general drift of the normal reaction into three components. The paper proposes a measurement method to determine the existence and numerical value of the third component. This method includes indirectly measuring the normal reaction drift that was implemented on an experimental setup.

The philosophical and political aspects of Utopia have often shadowed the geographical and cartographical dimension of More’s work. Thus, I will try to shed light on this aspect of the book in order to lay emphasis on the links fostered between knowledge and space during the Renaissance. I shall try to show how More’s opusculum aureum, which is fraught with cartographical references, reifies what Germain Marc’hadour terms a “fictional archipelago” (“The Catalan World Atlas” (c. 1375) by Abraham Cresques ; Zuane Pizzigano’s portolano chart (1423); Martin Benhaim’s globe (1492); Martin Waldseemüller’s Cosmographiae Introductio (1507); Claudius Ptolemy’s Geographia (1513) ; Benedetto Bordone’s Isolario (1528) ; Diogo Ribeiro’s world map (1529) ; the Grand Insulaire et Pilotage (c.1586) by André Thevet). I will, therefore, uncover the narrative strategies used by Thomas More in a text which lies on a complex network of geographical and cartographical references. Finally, I will examine the way in which the frontispiece of the editio princeps of 1516, as well as the frontispiece of the third edition published by Froben at Basle in 1518, clearly highlight the geographical and cartographical aspect of More’s narrative.

AbstractA review of the stability theory of symmetrizable time-dependent difference schemes is represented. The notion of the operator-difference scheme is introduced and general ideas about stability in the sense of the initial data and in the sense of the right hand side are formulated. Further, the so-called symmetrizable difference schemes are considered in detail for which we manage to formulate the unimprovable necessary and su±cient conditions of stability in the sense of the initial data. The schemes with variable weight multipliers are a typical representative of symmetrizable difference schemes. For such schemes a numerical algorithm is proposed and realized for constructing stability boundaries.

The object of the study of the knowledge of the variety of the Quranic reading  is the  Qur'an itself. The focus is on the difference of the reading and its articulation. The method is based on the riwayat or narration which is originated from the Prophet (Rasulullah saw) and its use is to be one of the instruments to keep the originality of the Qur’an. The validity of the reading the Qur’an is to be judged based on the valid chain  (sanad ¡a¥ī¥)  in accord with the Rasm U£mānÄ« as well as with the  Arabic grammar. Whereas the qualification of its originality is divided into six stages as follow: the first is mutawātir, the second is masyhÅ«r, the third is āhād, the fourth is syaz, the fifth is maudū‘, and the six is mudraj. Of this six catagories, the readings which can be included in the catagory of mutawātir are Qiraat Sab‘ah (the seven readings) and Qiraat ‘Asyrah  (the ten readings). To study this knowledge of reading the Qur’an (ilmu qiraat), one is advised to know about special terms being used such as  qiraat  (readings), riwayat (narration), tarÄ«q (the way), wajh (aspect), mÄ«m jama‘, sukÅ«n mÄ«m jama‘ and many others.

Abstract Genetic interference means that the occurrence of one crossover affects the occurrence and/or location of other crossovers in its neighborhood. Of the three components of genetic interference, two are well modeled: the distribution of the number and the locations of chiasmata. For the third component, chromatid interference, there exists only one model. Its application to real data has not yet been published. A further, new model for chromatid interference is presented here. In contrast to the existing model, it is assumed that chromatid interference acts only in the neighborhood of a chiasma. The appropriateness of this model is demonstrated by its application to three sets of recombination data. Both models for chromatid interference increased fit significantly compared to assuming no chromatid interference, at least for parts of the chromosomes. Interference does not necessarily act homogeneously. After extending both models to allow for heterogeneity of chromatid interference, a further improvement in fit was achieved.

This article presents an analysis of the concept of political equality that is derived partly from the analysis of Robert Dahl. Following an introductory section, the conservative nature of Dahl's idea of political equality is outlined from four perspectives. With the last of these perspectives, a distinction between ‘populist’ and ‘liberal’ theories of democracy is introduced. In the third section it is argued that there are three components of political equality within a liberal theory, and the fourth section is devoted to an analysis of one of these—equality of treatment in the promotion of interests.

AbstractThis paper considers the distinctions Aristotle draws (1) between the intellectual virtue of phronêsis and the moral virtues and (2) among the moral virtues, in light of his commitment to the reciprocity of the virtues. I argue that Aristotle takes the intellectual virtues to be numerically distinct hexeis from the moral virtues. By contrast, I argue, he treats the moral virtues as numerically one hexis, although he allows that they are many hexeis 'in being'. The paper has three parts. In the first, I set out Aristotle's account of the structure of the faculties of the soul, and determine that desire is a distinct faculty. The rationality of a desire is not then a question of whether or not the faculty that produces that desire is rational, but rather a question of whether or not the object of the desire is good. In the second section I show that the reciprocity of phronêsis and the moral virtues requires this structure of the faculties. In the third section I show that the way in which Aristotle distinguishes the faculties requires that we individuate moral virtues according to the objects of the desires that enter into a given virtue, and with reference to the circumstances in which these desires are generated. I then explore what it might mean for the moral virtues to be different in being but not in number, given the way in which the moral virtues are individuated. I argue that Aristotle takes phronêsis and the political art to be a numerical unity in a particular way, and that he suggests that the moral virtues are, by analogy, the same kind of unity.

Abstract Materials from topographic surveys had a serious impact on the labels on the maps that were based on these surveys. Collecting toponyms and information that were to be placed as labels on a final map, was an additional duty the survey officers were tasked with. Regulations concerning labels were included in survey manuals issued by the Austro-Hungarian Militärgeographisches Institut in Vienna and the Polish Wojskowy Instytut Geograficzny in Warsaw. The analyzed Austro-Hungarian regulations date from the years 1875, 1887, 1894, 1903 (2nd ed.). The oldest manual was issued during the Third Military Survey of Austria-Hungary (1:25,000) and regulated the way it was conducted (it is to be supposed that the issued manual was mainly a collection of regulations issued prior to the survey launch). The Third Survey was the basis for the 1:75,000 Spezialkarte map. The other manuals regulated the field revisions of the survey. The analyzed Polish manuals date from the years 1925, 1936, and 1937. The properties of the labels resulted from the military purpose of the maps. The geographical names’ function was to facilitate land navigation whereas other labels were meant to provide a military map user with information that could not be otherwise transmitted with standard map symbols. A concern for not overloading the maps with labels is to be observed in the manuals: a survey officer was supposed to conduct a preliminary generalization of geographical names. During a survey both an Austro-Hungarian and a Polish survey officer marked labels on a separate “label sheet”. The most important difference between the procedures in the two institutes was that in the last stage of work an Austro-Hungarian officer transferred the labels (that were to be placed on a printed map) from the “label sheet” to the hand-drawn survey map, which made a cartographer not responsible for placing them in the right places. In the case of the Polish institute the labels remained only on the “label sheets”.

AbstractThis article is the third in a series of studies on The History of the Rechabites. The first, "The Story of Zosimus or The History of the Rechabites?,"1 established the independent identity of this text within the Christian monastic work, The Story of Zosimus, and was a sort of prolegomena to the study of this text. The second, "Towards a Critical-Introduction to The History of the Rechabites,"2 sought to address the standard introductory issues, such as date, original language, provenance and purpose. The present paper seeks to examine the text verse-by-verse, and to offer a commentary on it. Or, rather, an initial commentary. No commentary of any sort has ever been offered on the Greek text of HistRech before, and it would be foolhardy to claim that any one scholar could perceive all the allusions and meanings in a particular text at a first attempt. This commentary, then, is offered in the same spirit as my two previous studies on HistRech: as a step along the way towards unravelling the meaning of this pseudepigraphon about the Rechabites, not as the last word on the subject.

This book examines the role of the papacy and the crusade in the religious life of the late twelfth through late thirteenth centuries and beyond. Throughout the book, the contributors ask several important questions. Was Innocent III more theologian than lawyer-pope and how did his personal experience of earlier crusade campaigns inform his own vigorous promotion of the crusades? How did the outlook and policy of Honorius III differ from that of Innocent III in crucial areas including the promotion of multiple crusades (including the Fifth Crusade and the crusade of William of Montferrat) and how were both pope’s mindsets manifested in writings associated with them? What kind of men did Honorius III and Innocent III select to promote their plans for reform and crusade? How did the laity make their own mark on the crusade through participation in the peace movements which were so crucial to the stability in Europe essential for enabling crusaders to fulfill their vows abroad and through joining in the liturgical processions and prayers deemed essential for divine favor at home and abroad? Further essays explore the commemoration of crusade campaigns through the deliberate construction of physical and literary paths of remembrance. Yet while the enemy was often constructed in a deliberately polarizing fashion, did confessional differences really determine the way in which Latin crusaders and their descendants interacted with the Muslim world or did a more pragmatic position of ‘rough tolerance’ shape mundane activities including trade agreements and treaties?

Electoral stability has been viewed as an essential condition for the healthy functioning of representative democracy. However, there is little agreement in the literature about what shapes the stability of the electorate in general nor much attention paid to that of the Asian electorates in particular. We propose historical legacies, uniquely testable in Asia, as central determinants, but also test for conventional factors examined in other regions. By analyzing more than 150 elections in 19 post-WWII Asian democracies, we find that certain types of authoritarian (military or personalist) and colonial (non-British) legacies have a detrimental impact on the stabilization of the electorate, while some of the findings from other regions apply also to Asia. Our additional finding that such effects of historical legacies, particularly authoritarian interludes, are attenuated and cease to be significant with sufficient maturation of democracy, has important implications for the way party systems develop and democracies consolidate.
