In recent years, several remarkable results have shown that certain theorems of finite combinatorics are unprovable in certain logical systems. These developments have been instrumental in stimulating research in both areas, with the interface between logic and combinatorics being especially important because of its relation to crucial issues in the foundations of mathematics which were raised by the work of Kurt Godel. Because of the diversity of the lines of research that have begun to shed light on these issues, (...) there was a need for a comprehensive overview which would tie the lines together. This volume fills that need by presenting a balanced mixture of high quality expository and research articles that were presented at the August 1985 AMS-IMS-SIAM Joint Summer Research Conference, held at Humboldt State University in Arcata, California.With an introductory survey to put the works into an appropriate context, the collection consists of papers dealing with various aspects of 'unprovable theorems and fast-growing functions'. Among the topics addressed are: ordinal notations, the dynamical systems approach to Ramsey theory, Hindman's finite sums theorem and related ultrafilters, well quasiordering theory, uncountable combinatorics, nonstandard models of set theory, and a length-of-proof analysis of Godel's incompleteness theorem. Many of the articles bring the reader to the frontiers of research in this area, and most assume familiarity with combinatorics and/or mathematical logic only at the senior undergraduate or first-year graduate level.

Norms, Values, and Society is the second Yearbook of the Vienna Circle Institute, which was founded in October 1991. The main part of the book contains original contributions to an international symposium the Institute held in October 1993 on ethics and social philosophy. The papers deal among others with questions of justice, equality, just social institutions, human rights, the connections between rationality and morality and the methodological problems of applied ethics. The Documentation section contains previously unpublished papers (...) by Rudolf Carnap, Philipp Frank, Charles W. Morris and Edgar Zilsel, and the review section presents new publications on the Vienna Circle. The Vienna Circle Institute is devoted to the critical advancement of science and philosophy in the broad tradition of the Vienna Circle, as well as to the focusing of cross-disciplinary interest on the history and philosophy of science in a social context. The Institute's Yearbooks will, for the most part, document its activities and provide a forum for the discussion of exact philosophy, logical and empirical investigations, and analysis of language.

The purpose of this study is a philosophical analysis of the phenomenon of social responsibility and the peculiarities of the process of its transformation, which took place in the context of globalization. The objective of the study is to determine the nature of the impact of the globalization process on the transformation of the institution of responsibility. In the course of the research, systematic, formal-logical and historical methods of scientific cognition were used. A civilizational approach was also applied, in (...) which the analysis of the object and subject of research was carried out taking into account civilizational features. As a result of the research, we came to the conclusion that globalization in its modern form is a process of modernization within the whole of humanity. Currently, in the vast majority of the most economically and technologically developed countries of the planet, there is such a negative phenomenon as negative demographic dynamics. In turn, this phenomenon is accompanied by a deep crisis of the institution of the family, and with it a massive departure from traditional norms and values. In such conditions, such an important institution and instrument regulating public relations as the institute of social responsibility inevitably undergoes a serious transformation. In the course of this process, there is a transition to the so-called modern society, the fundamental difference of which from the traditional one is that it is focused on the innovative component of culture, which in fact means the ever-increasing predominance of innovative elements over traditional ones, the secular nature of public life, development, which has a progressive, and not cyclical, the formation of democratic institutions, the mass nature of education, the dominance of the universal over the local, etc. All these innovative elements of culture, taken both separately and in combination, have a decisive influence on the entire Worldview of people, including their perception of justice and responsibility.

ABSTRACT:This study examines whether the empirical evidence on the relationship between corporate social performance (CSP) and corporate financial performance (CFP) differs depending on the publication outlet in which that evidence appears. This moderator meta-analysis, based on a total sample size of 33,878 observations, suggests that published CSP-CFP findings have been shaped by differences in institutional logics in different subdisciplines of organization studies. In economics, finance, and accounting journals, the average correlations were only about half the magnitude of the findings published (...) in Social Issues in Management, Business Ethics, or Business and Society journals (mean corrected correlation coefficientof.22 vs..49, respectively). Specifically, economists did not find null or negative CSP-CFP correlations, and average findings published in general management outlets (=.41) were closer to Social Issues in Management, Business Ethics, and Business and Society results than to findings reported in economics, finance, and accounting journals.

It is well established within the ethics and institutional theory literatures that institutions can have conflicting logics with ethical dimensions and that there are solutions to the conflicts. Within institutional, ethics, and change leadership theory, quantitative, mixture solutions such as distributive solutions have been frequently considered. The ethics, institutional, and change leadership theory literatures have recognized that there are qualitative transformational solutions that are different than quantitative mixture solutions. However and for the most part, with the notable exception of the (...) Thornton et al. :801–843, 2012) typology of solutions, the institutional, change leadership, and ethics literatures have not considered typologies of transformational solutions. And more specifically with respect to this article, the institutional, change leadership, and ethics literatures have not considered different types of transformational solutions to institutional logic conflicts with ethical dimensions. This article: develops a typology of transformational solutions; applies the typology with historical examples of conflicting institutional ethics logics within factory, cultural, and institutional social change leadership cases; and, considers practical and theoretical implications for institutional ethics change leadership for achieving and/or resisting different types of transformational solutions.

In order to achieve a desired effect of tax legal interpretation, its linguistic mechanisms are frequently insufficient. Elements of paralinguistic interpretation are more and more often indispensable. It applies inter alia when domestic tax law regulations must be verified in the light of the EU tax law. However, the study depict interpretative problems regarding the institution of remuneration of excess payments, which is regulated in Polish tax law. Considerations presented in this article confirm that legal interpretation of tax law is (...) a complicated process. It is important to establish correct system connection between the analyzed legal regulations and other provisions, often contained in other legal acts. Moreover, it seems necessary to refer to the purpose-oriented interpretation of the law. Only then a chance for a satisfactory final result of the provision’s legal interpretation can be guaranteed. What is more, such an effect will create an element being a part of a logically composed and arranged unity. (shrink)

Several logical operators are defined as dual pairs, in different types of logics. Such dual pairs of operators also occur in other algebraic theories, such as mathematical morphology. Based on this observation, this paper proposes to define, at the abstract level of institutions, a pair of abstract dual and logical operators as morphological erosion and dilation. Standard quantifiers and modalities are then derived from these two abstract logical operators. These operators are studied both on sets of states and sets of (...) models. To cope with the lack of explicit set of states in institutions, the proposed abstract logical dual operators are defined in an extension of institutions, the stratified institutions, which take into account the notion of open sentences, whose satisfaction is parametrised by sets of states. A hint on the potential interest of the proposed framework for spatial reasoning is also provided. (shrink)

Is voting a duty of democratic citizenship? This article advances a new argument for the existence of a duty to vote. It argues that every normative account of electoral representation requires universal turnout to function in line with its own internal normative logic. This generates a special obligation for citizens to vote in electoral representative contexts as a function of the role morality of democratic citizenship. Because voting uniquely authorizes office holding in representative democracies, and because universal turnout contributes (...) powerfully to representation being fair, to be a good citizen of such democracies requires one to vote. Whereas previous arguments for a duty to vote have invoked basic moral principles like fairness or a Samaritan duty of rescue, this account is based on citizens occupying a vital functional role within electoral representative institutions. This institutional duty solves the “specificity problem” of justifying a duty to vote better than competing accounts and also immunizes the duty to objections that there is no duty to vote when there are only bad choices and that there is a no duty to vote but rather duty to vote well. By emphasizing the tight connection between institutions and individual conduct, the role morality approach used here supplies a less abstract and more realistic framework than much previous research on the ethics of democratic citizenship and brings the debate closer to constitutive features of democratic politics.

This book constitutes the outcome of an international conference held at the Otto-Mobes-Volkswirtschaftsschule, Graz-Stifting( Austria), from June 16 to 22, 1974. The conference was initiated by a project group working on determinants and controls of social science development at the In stitute for Advanced Studies and Scientific Research in Vienna and or ganized by the editors of this volume. It was held under the auspices of the Austrian Ministry of Science and Research. The main topics of the conference were those (...) at the forefront of the 'state of argumentation' (to borrow from one of our contributors) in philosophy and sociology of science ever since the controversy between Thomas S. Kuhn and Sir Karl R. Popper has sharpened our awareness for the methodological and substantial presuppositions involved with questions of growth and development in science. Let us give two examples of those topics. The borderline between sociology of science and philo sophy of science has become more and more unclear; while the work of at least some philosophers of science comes to have an empirical flavour, sociologists of science are increasingly apt to include logical and methodo logical components of the research process as their objects of examina tion. Papers included in this volume testify to both tendencies. (shrink)

Leading international environmental philosophers further the debate about the environment and the metaphysical, ethical, social and international implications.

This article examines two potential Rawlsian arguments, namely the moral dualism argument and the educative effect of institutions argument as regards the extension of the primary subject of justice to personal conduct. The article makes two claims. First, while moral dualism is a logical step to make, it suffers from a potential conflict between the principles that apply to institutions and those that govern personal conduct. Second, despite the attractive features of the educative effect of institutions argument, an explanative gap (...) has to be filled in order to account for how and why individuals comply to just institutions. In the end, the article concludes that extending Rawls’s theory of justice to include personal conduct may be difficult to sustain. (shrink)

This edited book focuses on non-classical logics and their applications, highlighting the rapid advances and the new perspectives that are emerging in this area. Non-classical logics are logical formalisms that violate or go beyond classical logic laws, and their specific features make them particularly suited to describing and reason about aspects of social interaction. The richness and diversity of non-classical logics mean that this area is a natural catalyst for ideas and insights from many different fields, from information theory (...) to game theory and business science. This volume is the post-proceedings of the 8th International Conference on Logic and Cognition, held at Sun Yat-Sen University Institute of Logic and Cognition in Guangzhou, China in December 2016. The conference series started in 2001, and is organized by the ILC, often in collaboration with various international research groups. This eighth installment was jointly organized by ILC and Alessandra Palmigiano's Applied Logic research group. The conference series aims to foster the development of effective logical tools to study social behavior from a philosophical, cognitive and formal perspective in order to challenge the field of logic in ways that open up new and exciting research directions.

In this study, we aim to investigate how multinational corporations (MNCs) balance ethical pressures from both the home and host countries. Drawing on theories from institutional theory, international business, and business ethics, we build a theoretical framework to explain the ethical behavior of MNCs. We apply the institutional logic concept to examine how MNCs with established logics and principles that have grown in the home country respond to local ethical expectations in the host country. We differentiate the core values (...) from the peripheral components of a MNCs institutional logic and propose that a MNC will pursue distinctive ethical strategies under different scenarios and choose the "right" configuration of core values and peripheral components that align with institutional environment in host countries.

Transnational higher education (TNHE) has been characterised as a crude form of market-driven internationalisation, often targeting immobile student populations in countries with high demand for international academic degrees. In response to recent scholarship on the role of higher education internationalisation in facilitating and producing diasporic networks, this study examines its inverse: how TNHE services existing diasporic communities in situ by mobilising institutions across borders rather than student bodies. It specifically examines these dynamics within the United Arab Emirates (UAE), simultaneously host (...) to one of the largest concentrations of TNHE globally and a five million-member diasporic community of long-term, yet impermanent residents from South Asia. Drawing on interviews with South Asian students in undergraduate degree programmes at three British international branch campuses (IBCs), it explores how students perceive their IBCs as strategic sources of valuable degree capitals for enhancing employment opportunities in the UAE and securing against precarity and uncertain futures as perpetually impermanent residents. The research implicates the role of TNHE in diaspora policymaking, asking how IBCs function as an extension of a limited social contract between a diasporic community and its ‘host’ state. (shrink)

This paper contributes to explaining the rise of logical empiricism in mid-twentieth century (North) America and to a better understanding of American philosophy of science before the dominance of logical empiricism. We show that, contrary to a number of existing histories, philosophy of science was already a distinct subfield of philosophy, one with its own approaches and issues, even before logical empiricists arrived in America. It was a form of speculative philosophy with a concern for speculative metaphysics, normative issues relating (...) to science and society and issues which later were associated with logical empiricist philosophy of science, issues such as confirmation, scientific explanation, reductionism and laws of nature. Further, philosophy of science was not primarily pragmatist in orientation. We also show, with the help of our historical characterization, that a recent account of the emergence of analytic philosophy applies to the rise of logical empiricism. It has been argued that the emergence of American analytic philosophy is partly explained by analytic philosophers’ use of key institutions, including of journals, to marginalize speculative philosophy and promote analytic philosophy. We argue that this use of institutions included the marginalization of speculative and value-laden philosophy of science and the promotion of logical empiricism. (shrink)

The editio princeps of the first Medieval introduction to philosophy that makes use of the full range of Aristotle's writings.

She has always existed and is more than a citizen of multiverses,‭ ‬most likely the ground of all.‭ ‬In the West she was introduced around C.570‭ ‬and since then many individuals have searched for her,‭ ‬tried to become familiar with her and created all sorts of,‭ ‬frequently ridiculous,‭ ‬things in her name. Once someone has a passion for her it cannot be extinguished but increases.‭ ‬Objectively this need for her is referred to as‭ ‘‬love of wisdom‭’‬,‭ ‬the need for wisdom,‭ (...) ‬while personally it is a need of some individuals. -/- This passion and need has become institutionalized and it has developed a discourse and became a socio-cultural practice of its own.‭ ‬Fairly recently it has even become a discipline at,‭ ‬mostly higher,‭ ‬institutions of learning.‭ ‬Previously those searching for and attempting to interact with her came from many walks of life and all kinds of professions,‭ ‬while in the last century or so many people began to live off her as they are remunerated for talking about,‭ ‬about the history of searching for and investigating her and saying all sorts of things about her. -/- Many things are done in her name and all sorts of neologisms are fabricated to label them,‭ ‬such as analytic,‭ ‬continental,‭ ‬idealism,‭ ‬rationalism,‭ ‬empiricism,‭ ‬and all these labels are again specified and specified ad infinitum with terms such as materialism,‭ ‬physicalism,‭ ‬weak naturalism,‭ ‬speculative and new realism,‭ ‬etc. -/- Individuals from many other disciplines and areas of life,‭ ‬such as sociology,‭ ‬the arts,‭ ‬humanities,‭ ‬cognitive sciences,‭ ‬sport,‭ ‬etc got on the bandwagon so that we now have a philosophy or love of wisdom,‭ ‬epistemologies,‭ ‬ontologies etc of everything under the sun.‭ ‬Even if you were to write some theses or do some study you will stipulate your epistemology,‭ ‬ontology,‭ ‬methodology,‭ ‬etc.‭ ‬Just as those who live off philosophy become involved in every area of humanity and all its socio-cultural practices produce so-called peer reviewed publications,‭ ‬articles,‭ ‬essays and books on philosophy of art,‭ ‬sport,‭ ‬humanities,‭ ‬cognitive sciences,‭ ‬religion,‭ ‬gods,‭ ‬sex,‭ ‬rock‭ ‘‬n roll,‭ ‬language,‭ ‬words,‭ ‬ideas,‭ ‬how words and ideas and concepts do their thing,‭ ‬etc,‭ ‬etc.‭ -/- The way these subject-matter are treated will usually consists of some form of reasoning,‭ ‬the use of arguments or argumentation and some kind of logic and a process that resembles the features,‭ ‬steps,‭ ‬stages and processes of theorizing,‭ ‬the construction and development of models,‭ ‬short term,‭ ‬medium or large theories.‭ ‬The latter is often presented in the form of entire‭ ‘‬metaphysical‭’ ‬and speculative systems such as those of Plato,‭ ‬Aristotle,‭ ‬Kant,‭ ‬Hegel,‭ ‬Marx,‭ ‬Husserl,‭ ‬Habermas et al.‭ ‬While Socrates and to some extent the later Wittgenstein attempted to be more authentic to the original principles of trying to follow and developed the ideal of identifying,‭ ‬capturing by verbal interaction‭ (‬be it discourse,‭ ‬or dialogue‭) ‬and becoming one‭ (‬like mystics of all religions who are passionate about‭ ‘‬the one‭’‬,‭ ‬the Beloved,‭ ‬the one Real Self,‭ ‬etc and attempt to become one,‭ ‬united with or‭ ‘‬oned‭’ ‬with their object or subject of desire‭) ‬with Sophos‭ – ‬by exploring and investigating or applying and executing practical use of language,‭ ‬and thereby to uncover and capture her. -/- The effects of the institutionalization of the discipline are far-reaching and the professionalization of the role of philosopher as a‭ ‘‬profession‭’‬,‭ ‬an employee of an institution and a representative of the status quo are discussed in a number of articles being cited. -/- The methods of the philosophical discourse vary,‭ ‬first of all between the so-called Continental and Anglophone Analytic philosophies,‭ ‬its movements,‭ ‬schools and institutions,‭ ‬such as research universities,‭ ‬journals,‭ ‬communities and book publishers.‭ ‬It seems as if increasingly philosophizing employs some of the stages and steps of the processes of theorizing.‭ ‬Other aspects of her methods are heuristic devices,‭ ‬the use of metaphors and analogies,‭ ‬philosophical logic,‭ ‬informal and other types of logic,‭ ‬arguments and argumentation.‭ ‬This involves the creation of fallacies in thinking and reasoning and the causing of all sorts of fallacies or crooked thinking. -/- The nature and changes of philosophical subject-matter are discussed as the socio-cultural practice lost most of its traditional‭ ‘‬objects‭’ ‬with the social and cultural differentiation of other,‭ ‬specialized disciplines.‭ ‬In turn the discourse attempts to fabricate other subject-matter,‭ ‬for example the development of so-called Experimental Philosophy,‭ ‬inter-disciplinary studies such as cognitive sciences and philosophies or meta-level explorations of and speculations about other disciplines,‭ ‬professions and domains‭ (‬for example normative,‭ ‬instrumental and subjective aesthetic‭ – ‬this the terminology and distinctions according to the working class obsessive Critical Theory of the so-called Frankfurt Schule.‭ ‬One always wonders what degree of personal experience their educated,‭ ‬middle class academics have of‭ ‘‬the working class‭’‬,‭ ‬whatever that is meant to be‭?)) ‬of human activity.‭ ‬Such as philosophy of medicine,‭ ‬sport,‭ ‬art,‭ ‬religion,‭ ‬just name it and it is bound to exist.‭ -/- Another‭ ‘‬extension‭’ ‬of or interest in‭ ‘‬philosophy‭’ ‬is that of certain individuals,‭ ‬schools or movements in other disciplines,‭ ‬for example social‭ ‘‬sciences‭’ ‬such as sociology and supporters of the above mentioned‭ ‘‬Schule‭’‬.‭ ‬They frequently use philosophical words such as ontology,‭ ‬epistemology,‭ ‬multi-dimensional,‭ ‬many-levels,‭ ‬contexts assumptions,‭ ‬pre-suppositions,‭ ‬immanent,‭ ‬transcendent,‭ ‬etc.‭ ‬Is this intended to be an extension of philosophy and the doing of philosophizing or merely cognitive bias of the form‭ ‘‬authority bias‭’‬.‭ ‬In this case the authority being‭ ‘‬the discipline of philosophy‭’‬,‭ ‬as well as the‭ ’‬use of the word philosophy‭ ‬and terms from the philosophical discourse‭’‬.‭.

The concept of organizational stigma has received significant attention in recent years. The theoretical literature suggests that for a stigma to emerge over a category of organizations, a “critical mass” of actors sharing the same beliefs should be reached. Scholars have yet to empirically examine the techniques used to diffuse this negative judgment. This study is aimed at bridging this gap by investigating Goffman’s notion of “stigma-theory”: how do stigmatizing actors rationalize and emotionalize their beliefs to convince their audience? We (...) answer this question by studying the stigma over the finance industry since 2007. After the subprime crisis, a succession of events put the industry under greater scrutiny, and the behaviors and values observed within this field began to be publicly questioned. As an empirical strategy, we collected opinion articles and editorials that specifically targeted the finance industry. Building on rhetorical analysis and other mixed methods of media content analysis, we explain how the stigmatizing rhetoric targets the origins of deviant organizational behaviors in the finance industry, that is, the shareholder value maximization logic. We bridge the gap between rhetorical strategies applied to discredit organizations and ones used to delegitimize institutional logics by drawing a parallel between these two literatures. Taking an abductive approach, we argue that institutional contradiction between field and societal-level logics is sufficient, but not necessary to generate organizational stigma. (shrink)

In this paper we investigate a logic for modelling individual and collective acceptances that is called acceptance logic.

In this logic, if the set of accessible worlds of G in context x is empty, then the agents in G are not functioning as members of x, they do not identify themselves with x. In such a situation the agents in G may have the possibility to join x. To model this we introduce here a second kind of dynamic modal operator of acceptance shifting of the form \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${G:x\uparrow\psi}$$\end{document}. The latter means that the agents in G shift (change) their acceptances in order to accept ψ in context x. Semantically, they make ψ-worlds accessible to G in the context x, which means that, after such operation, G is functioning as member of x (unless there are no ψ-worlds). We show that the resulting logic has a complete axiomatization in terms of reduction axioms for both dynamic operators. In the paper we also show how the logic of acceptance and its dynamic extension can be used to model some interesting aspects of judgement aggregation. In particular, we apply our logic of acceptance to a classical scenario in judgment aggregation, the so-called ‘doctrinal paradox’ or ‘discursive dilemma’ (Pettit, Philosophical Issues 11:268–299, 2001; Kornhauser and Sager, Yale Law Journal 96:82–117, 1986).

In this paper we investigate a logic for modelling individual and collective acceptances that is called acceptance logic. The logic has formulae of the form $A_{Gx} \phi $ reading 'if the agents in the set of agents G identify themselves with institution x then they together accept that φ'. We extend acceptance logic by two kinds of dynamic modal operators. The first kind are public announcements of the form x!ψ, meaning that the agents learn that ψ (...) is the case in context x. Formulae of the form [x!ψ]φ mean that φ is the case after every possible occurrence of the event x!ψ. Semantically, public announcements diminish the space of possible worlds accepted by agents and sets of agents. The announcement of ψ in context x makes all ¬ψ-Worlds inaccessible to the agents in such context. In this logic, if the set of accessible worlds of G in context x is empty, then the agents in G are not functioning as members of x, they do not identify themselves with x. In such a situation the agents in G may have the possibility to join x. To model this we introduce here a second kind of dynamic modal operator of acceptance shifting of the form G:x↑ψ. The latter means that the agents in G shift (change) their acceptances in order to accept ψ in context x. Semantically, they make ψ-worlds accessible to G in the context x, which means that, after such operation, G is functioning as member of x (unless there are no ψ-worlds). We show that the resulting logic has a complete axiomatization in terms of reduction axioms for both dynamic operators.

Focusing on the tendency of terrorist organizations to explosive attack, this article applied the institutional theory as the basis to explain the inherent logic of attack type similarity from the perspective of mimetic, coercive, and normative isomorphism. Subsequently, the study conducted an empirical analysis of the data onto 1825 terrorist organizations recorded in the Global Terrorism Database with the logistic regression method. The results show that: Terrorist organizations will learn from pre-existing terrorist organizations' experiences, and mimetic isomorphism will (...) promote explosive tendency; Due to the normative isomorphism effect, terrorist groups' tendency to explosive attacks is weakened by their increased duration; If terrorist organizations are hostile to a strong government, coercive isomorphism positively moderates the negative effects of increasing duration. The study suggests that counter-terrorism approaches such as destroying the learnable experience of attacks, addressing the root causes of terrorism, and maintaining a strong government may be helpful in stopping increasing terrorist activities, which is essential for reducing terrorist organizations' vivosphere, blocking the inter-flow and imitation between terrorist organizations, and ultimately interrupting the terrorist propagation chain.
