The main purpose of the book is to introduce the numerical integration of the Cauchy problem for delay differential equations (DDEs) and of the neutral type. Comparisons between DDEs and ordinary differential equations (ODEs) are made using examples illustrating some unexpected and often surprising behaviours of the true and numerical solutions. The book briefly reviews the various approaches existing in the literature and develops an error and well-posedness analysis for general one-step and multistep methods. The continuous extensions of Runge-Kutta methods are presented in detail, which are useful for more general problems such as dense output and discontinuous equations. Some deeper insight into convergence and superconvergence is then carried out for DDEs with various kinds of delays. The stepsize control mechanism is developed on a firm mathematical basis. Classical results and an unconventional analysis of stability with respect to forcing term are reviewed for ODEs in view of the subsequent stability analysis for DDEs. Moreover, an exhaustive description of stability domains for some test DDEs is carried out and the corresponding investigations for the numerical methods are made. Reformulations of DDEs as partial differential equations and subsequent semi-discretization are described and compared with the classical approach. A list of available codes is provided.Less

This study explores the early history of purgatory as it developed from the first to the eighth centuries. Approaching the subject from a variety of angles, the book examines how ideas of post-mortem purgation as religious belief were forged from contested theology and eschatology, and how purgatory became the focus for such religious practices as prayer for the dead and the hope for intercession. Illuminating the various interests and influences at play in the formation of purgatorial ideas in late antiquity, this book discusses ideas about punishment and correction in the Roman world, slavery, medical purges at the shrines of saints, visionary texts, penitentials, and law codes. Confronting arguments that have viewed purgatory as a symptom of cultural shifts or educational decline, this book questions the extent to which Irish and Germanic views of society, and the sources associated with them — penitentials and legal tariffs — played a role in purgatory’s formation. In reassessing the significance of patristic discussion of purgatory, this study highlights Bede’s contribution to purgatory’s theological underpinnings allowing the future acceptance of purgatory as orthodox belief. Among those whose writings are examined are Origen, Augustine, Gregory the Great, and Bede.Less

Free shuttle buses that are often used to transport clients or customers from one designated location to another are usually not permitted to compete with common carrier transportation. One such company was accused of violating the state code for picking up nonauthorized customers as it transported people between hotels and casinos. The defendant argued that the wording of the state code was ambiguous and unclear. Semantic analysis of the words “effectively,” “limits,” “customer,” and “trip” framed the linguistic contribution to this case.Less

This text contains the latest edition of this book. It covers the basis of the Japanese legal system, the civil code, business related laws, and other laws including criminal law and procedure, and foreign relations law. Since the last edition, Japanese law has undergone major reform all of which is reflected in the new text. In particular, the new edition covers the new company law and the Financial Products Trading Law, both of which have been completely overhauled. After the ‘lost decade’ following the collapse of the ‘bubble economy’ in 1990, Japan has gone through a major reform — deregulation or ‘regulatory reform’. Accordingly, major changes took place in almost every area of law. There was a large-scale ‘Justice System Reform’ which encompassed various changes in the court system, the introduction of lay assessors in the criminal procedure, a new law school system, etc. Company law, which was embodied in the Commercial Code, was completely overhauled under a different concept and became a separate law — the Company Law of 2005. Securities and Exchange Law was replaced by the Financial Instruments and Exchange Law in 2006. Even the Civil Code, which had remained more or less unchanged (except for family and succession) since the late 19th century, has gone through significant changes. Certainly there are many positive results coming out of these reforms, but also there have been some doubtful changes. Thee outcome of the reforms of the past decade is yet to be assessed. These changes and their impact are covered in this book.Less

Communitarians claim that individuals do not exist apart from society, and that communities have a moral value that is independent of individuals. It is held that philosophers such as Rawls and Nozick who neglect persons’ deserts and their history and attachments cannot understand justice. While agreeing that persons are almost unimaginable except in a social context, and that membership of a community is an important good for many people, nevertheless, it is held that they are autonomous beings. A person may disagree with the moral code of any society, including his own. However, a shared understanding of community values has historically often been a source of evil.Less

This study explores the nature and meaning of violence in 15th-century England. The book examines violence on each side of the law — both in crime and in law enforcement — in order to uncover the attitudes and beliefs of the inhabitants of medieval East Anglia. The book investigates the way their moral code was reflected in the procedures and punishments of the courts, and assesses the success of the legal system in maintaining authority and order. The book reveals the strong concern for order apparent in 15th-century society.Less

This book provides readers with the skills they need to write computer codes that simulate convection, internal gravity waves, and magnetic field generation in the interiors and atmospheres of rotating planets and stars. Using a teaching method perfected in the classroom, the book begins by offering a step-by-step guide on how to design codes for simulating nonlinear time-dependent thermal convection in a 2D box using Fourier expansions in the horizontal direction and finite differences in the vertical direction. It then describes how to implement more efficient a nd accurate numerical methods and more realistic geometries in two and three dimensions. The third part of the book demonstrates how to incorporate more sophisticated physics, including the effects of magnetic field, density stratification, and rotation. The book features numerous exercises throughout, and is an ideal textbook for students and an essential resource for researchers. It explains how to create codes that simulate the internal dynamics of planets and stars, and builds on basic concepts and simple methods. The book shows how to improve the efficiency and accuracy of the numerical methods. It considers more relevant geometries and boundary conditions.Less

A concept in the psychological sense is the mental representation of a category, and a mental concept is the mental representation of a mental category or type, such as belief, desire, fear, or hunger. What are the vehicles of mental concepts and what are their contents? There is a proprietary internal code, the introspective code, which employs introspection-derived mental vehicles to represent mental categories. Introspection-based concepts bear some similarity to the notion of self-directed recognitional concepts, articulated by Loar. This approach contrasts with the functional-role approach to mental concepts that is naturally associated with theory theory.Less

As telescopes, detectors, and computers grow ever more powerful, the volume of data at the disposal of astronomers and astrophysicists will enter the petabyte domain, providing accurate measurements for billions of celestial objects. This book provides a comprehensive and accessible introduction to the cutting-edge statistical methods needed to efficiently analyze complex data sets from astronomical surveys such as the Panoramic Survey Telescope and Rapid Response System, the Dark Energy Survey, and the upcoming Large Synoptic Survey Telescope. It serves as a practical handbook for graduate students and advanced undergraduates in physics and astronomy, and as an indispensable reference for researchers. The book presents a wealth of practical analysis problems, evaluates techniques for solving them, and explains how to use various approaches for different types and sizes of data sets. For all applications described in the book, Python code and example data sets are provided. The supporting data sets have been carefully selected from contemporary astronomical surveys (for example, the Sloan Digital Sky Survey) and are easy to download and use. The accompanying Python code is publicly available, well documented, and follows uniform coding standards. Together, the data sets and code enable readers to reproduce all the figures and examples, evaluate the methods, and adapt them to their own fields of interest.Less

The biblical account of the religious reforms of king Josiah is one of the most widely discussed texts in the Hebrew Bible. Scholars have long understood Josiah's destruction of Israelite cult objects and personnel to mark an essential break with Israel's polytheistic past and a foundational moment in the development of monotheism. The language of 2 Kgs 23 represents Josiah's reform as ritual, yet the text has never been systematically studied from a ritual perspective. Situating Josiah's defilement in the context of other Israelite rituals, it uncovers new fault lines in the text that reveal two compositional phases. An early account with parallels in priestly ritual texts and the Holiness Code promoted particular ambitions of the Josianic court, while a later, postmonarchic, Deuteronomistic version recast Josiah as the only king in Israel's history to fully appreciate the obligations and limitations imposed by Mosaic law. Utilizing language associated with Deuteronomy's war-ḥērem, the later author modeled Josiah on Joshua. Both [re]claimed the land from the clutches of the Canaanites and [re]established Israel as the place where Yahweh's law and priestly authority prevailed. This study challenges the widely held assumption that Josiah imposed Deuteronomic law in the late seventh century; it provides a more expansive picture of the holiness school and its engagement in literary production; and it points away from a Josianic, Deuteronomistic redaction of 2 Kgs 23, shedding new light on the composition of the book of Kings.Less

This chapter focuses on the president's use of prerogative powers and the treatment of detainees in the war on terror. President Bush asserted his prerogative power in interpreting and reinterpreting conventions and customary international law obligations, and in interpreting the obligations of government officials to execute faithfully statute law, the Uniform Code of Military Justice, and various directives. It is argued that officials at the highest levels of government made decisions based on the constitutional authority of the president (as administration lawyers defined it) that left open the probability that detainees would be subjected to inhuman treatment and torture as defined by international law. The chapter explores why the issue of the treatment of prisoners has not risen to the level of an Iran-Contra affair and what the reaction tells us about the politics of prerogative power.Less

This chapter studies the effects of multinational companies on labor conditions around the world. The evidence shows that (1) the economic presence of multinationals in foreign countries is often overstated, (2) multinationals pay higher wages than host-country companies in both industrialized and developing countries, and (3) when multinationals acquire host country businesses, they institute changes in production methods and human resource management practices that raise productivity sufficiently to support higher wages. The evidence also rejects the race-to-the-bottom view that poor labor conditions attract multinational companies. Most flows of foreign direct investment occur between advanced countries with high labor standards and are influenced by market size and potential investment risk rather than labor conditions. The chapter also examines and evaluates the efficacy of corporate codes of conduct for improving labor conditions.Less

This chapter argues that that the IMF's sovereign debt restructuring mechanism (SDRM) is misguided in several ways. Most importantly, the SDRM proposal leaves the IMF itself in the position of having to make two crucial decisions: whether to endorse a stay of payments to creditors, and what amount of debt is “sustainable”, i.e., how much debt should be written off. This decision-making capacity creates a conflict of interest, as the IMF itself is almost always a creditor to countries experiencing debt crises. As an alternative to the IMF's SDRM, a mechanism modeled on Chapter 9 of the US bankruptcy code is proposed, which applies to municipalities and resolves some of the knotty problems of dealing with public (as compared with private) insolvency. This approach would rely on ad hoc panels formed by the debtor and creditor committees and therefore would not require that the IMF serve as arbitrator.Less

This book presents a unified approach to a rich and rapidly evolving research domain at the interface between statistical physics, theoretical computer science/discrete mathematics, and coding/information theory. The topics which have been selected, including spin glasses, error correcting codes, satisfiability, are central to each field. The approach focuses on the limit of large random instances, adopting a common formulation in terms of graphical models. It presents message passing algorithms like belief propagation and survey propagation, and their use in decoding and constraint satisfaction solving. It also explains analysis techniques like density evolution and the cavity method, and uses them to derive phase diagrams and study phase transitions.Less

The mathematical genius Alan Turing (1912-1954) was one of the greatest scientists and thinkers of the 20th century. Now well known for his crucial wartime role in breaking the ENIGMA code, he was the first to conceive of the fundamental principle of the modern computer — the idea of controlling a computing machine's operations by means of coded instructions, stored in the machine's ‘memory’. In 1945, Turing drew up his revolutionary design for an electronic computing machine — his Automatic Computing Engine (‘ACE’). A pilot model of the ACE ran its first programme in 1950 and the production version, the ‘DEUCE’, went on to become a cornerstone of the fledgling British computer industry. The first ‘personal’ computer was based on Turing's ACE. This book describes Turing's struggle to build the modern computer. It contains first-hand accounts by Turing and by the pioneers of computing who worked with him. The book describes the hardware and software of the ACE and contains chapters describing Turing's path-breaking research in the fields of Artificial Intelligence (AI) and Artificial Life (A-Life).Less

This chapter modifies the numerical code by adding the nonlinear terms to produce finite-amplitude simulations. The nonlinear terms are calculated using a Galerkin method in spectral space. After explaining the modifications to the linear model, the chapter shows how to add the nonlinear terms to the code. It also discusses the Galerkin method, the strategy of computing the contribution to the nonlinear terms for each mode due to the binary interactions of many other modes. The Galerkin method works fine as far as calculating the nonlinear terms is concerned because of the simple geometry and convenient boundary conditions. The chapter concludes by showing how to construct a nonlinear code and performing nonlinear simulations.Less

If mafia groups are present in a market, they must be organized in some form. Two questions have generated a heated and long-running debate among scholars of the mafias: first, are criminal groups organized in a hierarchical and military fashion or, on the contrary, are they loose networks of individuals, getting together to perform a specific task; second, are these groups territorially or functionally organized? Chapter 6 addresses these two questions with reference to the city of Perm, which is in the Gulag Archipelago in the Ural region of Russia. It pieces together some elements in the history of Perm’s criminality at the time of the transition from the Soviet economic and political system to the market economy, discussing the legacy of the Gulag (in the shape of the criminal fraternity of the vory-v-zakone – thieves-with-a-code-of-honour – that flourished in the Soviet labour camps between the 1920s and the 1950s, and re-emerged in the 1970s) in relation to the contemporary criminal situation, the post-Soviet criminal groups that emerged in the city, and inter-group relations and conflicts. Lastly, it analyses the organizational arrangements (structure, size, and internal division of labour) of the mafia groups in Perm, and compares them with other gangs and mafias (principally the Sicilian Mafia or Cosa Nostra).Less

The first section of the chapter describes the main features of the original society of the vory-v-zakone – thieves-with-a-code-of-honour – the criminal fraternity that flourished in the Soviet labour camps between the 1920s and the 1950s, and re-emerged in the 1970s. The account given is based on archival data that have not been presented before, and describes the rituals and practices involved, the vory code of behaviour, vory activities outside prison, and punishment in vory courts. The second section addresses the question of the origins of the vory-v-zakone society, namely, whether it was a Soviet or pre-Revolutionary phenomenon. It is concluded that the fraternity most likely evolved from pre-Revolutionary criminal nineteenth-century arteli (guilds) of ordinary thieves.Less

An assessment is made of the role of the vory-v-zakone (thieves-with-a-code-of-honour – the criminal fraternity that flourished in the Soviet labour camps between the 1920s and the 1950s, and re-emerged in the 1970s) in the post-Soviet criminal world. The features of the new society are described (the existence of territorial groups of vory, and their organizational structure, activities, inter-group relations, and role) and the Russian Mafia is identified as groups that share vory rituals and norms of interaction and are federated with one another. The future of the Russian Mafia is then briefly evaluated amidst the emergence of two powerful competitor groups who do not share the rituals and traditions of the vory: the Chechen Mafia and the Cossacks. The chapter concludes with a discussion of the connections between politics, the church, terrorism, and the modern criminal fraternity.Less
