The purpose of the study is to reveal the features of the formation and functioning of Russian business ecosystems in modern conditions, to identify their main advantages and disadvantages, to propose ways to solve problems caused by a radical change in the digital space. The article examines the prerequisites for the emergence of business ecosystems, the features of their legal regulation, analyzes the options for organizational and technological structures, the problems of interaction of all participants in the process. Scientific novelty (...) lies in the development of theoretical provisions, the analysis of modern models that determine the organizational and technological structure of business ecosystems, the development of applied management tools and the definition of starting points for their research. As a result, the main features that characterize business ecosystems and most fully reflect their differentiation have been identified. The author's classification has been developed, the practical scope of which will allow to study the functioning of systems, both as a whole, and their individual elements, being at the same time a management tool.

This introduction to the basic ideas of structural proof theory contains a thorough discussion and comparison of various types of formalization of first-order logic. Examples are given of several areas of application, namely: the metamathematics of pure first-order logic (intuitionistic as well as classical); the theory of logic programming; category theory; modal logic; linear logic; first-order arithmetic and second-order logic. In each case the aim is to illustrate the methods in relatively simple situations and then apply them elsewhere in much (...) more complex settings. There are numerous exercises throughout the text. In general, the only prerequisite is a standard course in first-order logic, making the book ideal for graduate students and beginning researchers in mathematical logic, theoretical computer science and artificial intelligence. For the new edition, many sections have been rewritten to improve clarity, new sections have been added on cut elimination, and solutions to selected exercises have been included. (shrink)

Research collaboration beyond national jurisdiction is one aspect of the globalisation of health research. It has potential to complement researchers in terms of research skills, equipment and lack of adequate numbers of potential research subjects. Collaboration at an equal level of partnership though desirable, may not be practicable. Sometimes, human research specimens must be transported from one country to other. Where this occurs, there should be clear understanding between the collaborating research institutions regarding issues of access and control of the (...) specimens as well as the duration of storage of specimens. The researchers have the duty to inform the research participants about specimen storage and transport across national boundaries. While obtaining informed consent from study subjects if specimens are to be stored beyond the life of the present study could be the ideal, there still remains significant challenges in a multi-cultural world.

HSÜN Tzu's essay on "Rectifying Terms" is justly considered a work of "great logical interest." For in this essay, one finds a remarkably modern concern with such topics as the rationale for having terms; the empirical and pragmatic bases for the classification of terms; the formation of generic and specific terms; the importance of observing established linguistic practices; the necessity of complying with proper standards for the institution, ratification, and regulation of the uses of language ; the nature of argumentative (...) discourse ; and the problems inherent in successful linguistic communication. A careful examination of some passages in other essays also suggests an awareness of the distinction between deductive, inductive, and analogical inferences, though Hsün Tzu provides us no explicit discussion of the nature of reasoning and its validating rules.

This new edition brings Farquharson's authoritative 1944 translation up to date and includes a helpful introduction and notes for the student and general reader. Rutherford includes a selection of letters from Marcus to his tutor Fronto--most of which date from his earlier years--that offer personal detail and help to fill out the somber portrait of the emperor that is found in the Meditations.

Decisions by industry sponsors to end clinical trials early for commercial reasons have been the subject of controversy. I argue that the principal consideration in assessing these decisions ought to be the way in which the termination would affect the trial’s risk–benefit relationship. If there is not yet sufficient benefit to be gained from the study to offset the risks to which participants were exposed and it is expected that important scientific information would be obtained if the trial were continued, (...) early termination constitutes an unethical alteration of the risk−benefit relationship. This violates the grounds on which permission is given to conduct human research, patients consent to participate, and investigators agree to conduct studies. These knowable and avoidable changes in risk–benefit relationship should generally be seen as impermissible. (shrink)

UNTIL RECENT YEARS moral traditions have not been an important topic for moral philosophy. With few exceptions, attention has been directed to the problem of moral justification, to the search for universal criteria for the assessment of moral beliefs or judgments regardless of their traditional provenance. Generally, philosophers aspire to formulate "the view from nowhere." Since the publication of Alasdair MacIntyre's After Virtue there has been a revival of interest in the concept of a living, moral tradition, especially among moral (...) philosophers concerned with the possibility of an ethics of virtue or character as a viable alternative to the ethics of principle or, say, to deontological, utilitarian, or contractarian ethics. We must observe here that in the three decades prior to 1981, some moral philosophers displayed similar concern with tradition, although terms other than "tradition" were used, for example, "forms of life," "ways of life," "moral practices," and "moral community." Rawls's conception of reflective equilibrium is also developed with an eye on the notion of tradition. Indeed, Rawls has been quite explicit about his tradition-oriented approach to moral theory: "What justifies a conception of justice is not its being true to an order antecedent to and given to us, but its congruence with our deeper understanding of ourselves and our aspirations, and our realization that, given our history and the traditions embedded in our public life, it is the most reasonable doctrine.".
