The system GLS, which is a modal sequent calculus system for the provability logic GL, was introduced by G. Sambin and S. Valentini in Journal of Philosophical Logic, 11, 311–342,, and in 12, 471–476,, the second author presented a syntactic cut-elimination proof for GLS. In this paper, we will use regress trees in order to present a simpler and more intuitive syntactic cut derivability proof for GLS1, which is a variant of GLS without the cut rule.

Focusing on the debate between resource egalitarians and capability theorists, with particular attention to gender equality, this article rejects the prevailing assumption that the ‘capability approach’ to equality, as outlined by Amartya Sen, is better able to respond to important empirically identifiable inequalities than its resource egalitarian alternative, as developed by Ronald Dworkin. Developing and expanding upon the often overlooked Dworkinian ‘principle of independence’, the article contends that resource egalitarianism is capable of identifying and responding to a complex set of (...) structural inequalities that remain outside the purview of the capability approach. Key Words: capability approach • Dworkin • egalitarianism • equality • gender inequalities • Sen. (shrink)

The twenty-first-century business world has witnessed a series of large-scale scandals and outright fraud. New legislation aims to help identify future cases of fraud and stop the trend, but is it enough? How can people of faith balance the requirements of their beliefs with the demands of economic life within an increasingly corrupted society? Why did so many people participate or choose to ignore downright fraud in the past and how can we start the business community on a path of (...) recovery? These essays pursue these question and many others, including the meta-ethical foundations of vocation as a necessary step for business recovery. They maintain that what is taking place in businesses today is not just the loss of will to do good, but the loss of meaning, which ultimately demands more than what traditional business ethics and corporate social responsibility can offer. Combining creative biblical interpretation, Christian moral reflection, and business expertise, this book is a thoughtful and thought-provoking look at how business leaders, professionals, and students can integrate a sense of calling into their careers and into the business world as a whole.

Recently, significant research effort has focused on using Twitter to investigate mental health at the population-level. While there has been influential work in developing ethical guidelines for Internet discussion forum-based research in public health, there is currently limited work focused on addressing ethical problems in Twitter-based public health research, and less still that considers these issues from users’ own perspectives. In this work, we aim to investigate public attitudes towards utilizing public domain Twitter data for population-level mental health monitoring using (...) a qualitative methodology. The study explores user perspectives in a series of five, 2-h focus group interviews. Following a semi-structured protocol, 26 Twitter users with and without a diagnosed history of depression discussed general Twitter use, along with privacy expectations, and ethical issues in using social media for health monitoring, with a particular focus on mental health monitoring. Transcripts were then transcribed, redacted, and coded using a constant comparative approach. While participants expressed a wide range of opinions, there was an overall trend towards a relatively positive view of using public domain Twitter data as a resource for population level mental health monitoring, provided that results are appropriately aggregated. Results are divided into five sections: a profile of respondents’ Twitter use patterns and use variability; users’ privacy expectations, including expectations regarding data reach and permanence; attitudes towards social media based population-level health monitoring in general, and attitudes towards mental health monitoring in particular; attitudes towards individual versus population-level health monitoring; and users’ own recommendations for the appropriate regulation of population-level mental health monitoring. Focus group data reveal a wide range of attitudes towards the use of public-domain social media “big data” in population health research, from enthusiasm, through acceptance, to opposition. Study results highlight new perspectives in the discussion of ethical use of public data, particularly with respect to consent, privacy, and oversight. (shrink)

This paper defends a normative basis for entrepreneurial ventures, and draws the conclusion that any enterprise, insofar as it is reasonable, has in final analysis to be a (free) gift to promote good. Building on Herbert Simon's idea of "satisficing" and developing it in line with axiological insights of the new classical natural law theory, this paper makes the argument that a choice to proceed reasonably in any entrepreneurial venture will be guided by rationality that is bounded. Bounded rationality entails (...) that the various end-values or goals of the venture will be incommensurable, and this implies that (1) the enterprise need not be locked in on promoting merely one value, such as profits, and (2) a choice to aim at one or more goals will be a personal (free) gift, which is ethically valuable.

Structural Injustice has become a hugely important concept in the field of political theory with the work of Iris Marion Young central to debates on what it is, what motivates it and how it should be addressed. In this article, I focus on a particular thread in Young’s account of structural injustice which I argue is all too often overlooked - the untraceability of structural injustice. This is not only a constant theme in Young’s account of structural injustice, it is, (...) in fact, a defining feature. By ‘untraceable’, Young means that structural injustice is distinct from other sorts of injustices for which there is a traceable agent at fault – these sorts of faut-based injustices fall under what Young calls the ‘liability model of injustice’. For the purposes of exploring the concept of structural injustice, I follow the logic of the claim that structural injustice is untraceable to see where it takes us in conversation with Young’s critics. I conclude that Young’s account is not only defensible with some clarification and development but vital politically. That said, I also find Young’s account of political responsibility for structural injustice wanting and accordingly I propose a way of understanding what I see as a dynamic transition from structural to fault-based injustices which I argue Young’s more ‘static’ account fails to accommodate. This is important, I suggest, for thinking about the ways in which responsibility for different forms of injustice operate and change. _Contemporary Political Theory_ (2023). https://doi.org/10.1057/s41296-023-00634-4.

Publication date: 11 June 2018 Source: Author: Jude Nwafor Eze, Umar Aliyu, Abdulmalik Alhaji-Baba, Muhammad Alfa This research evaluates the farmers’ vulnerability to climate change in Niger State. Strategies for reducing the effect of climate change have regularly been made without experimental foundations and adequate information on farmers’ vulnerability to climate change in the study area. Thus, integrated farmers’ vulnerability assessment approach was employed by classifying socioeconomic and biophysical indicators of vulnerability into adaptive capacity, sensitivity and exposure to determine (...) the farmers’ vulnerability to climate change. This is based on the Intergovernmental Panel on Climate Change’s definition of vulnerability. The study adopted a survey design and the method utilized for the study was questionnaire administered to 400 households in the study area. The results indicate that the farmers’ vulnerability was low in zone A with a mean index of 2.86, very low in zone B with a mean index of 3.74, and high in zone C with a mean index of 1.95. It is recommended that measures should be taken to integrate climate change adaptation into Niger State development process. These measures should include improvement in adoption of good agricultural practices. (shrink)

Cognitive control of physical activity and sedentary behavior is receiving increased attention in the neuroscientific and behavioral medicine literature as a means of better understanding and improving the self-regulation of physical activity. Enhancing individuals’ cognitive control capacities may provide a resilient means to increase physical activity and reduce sedentary behavior. First, this paper reviews emerging evidence of the antecedence of cognitive control abilities in successful self-regulation of physical activity, and in precipitating self-regulation failure that predisposes to sedentary behavior. We then (...) highlight the brain networks that may underpin the cognitive control and self-regulation of physical activity, including the default mode network, prefrontal cortical networks and brain regions and pathways associated with reward. We then discuss research on cognitive training interventions that document improved cognitive control and that suggest promise of influencing physical activity regulation. Key cognitive training components likely to be the most effective at improving self-regulation are also highlighted. The review concludes with suggestions for future research. (shrink)

The various aspects of Christian Liberty and of the life of the Christian in the world are linked in a singular way in Paul’s pronouncements on marriage, as is found in 1 Cor 7:1–7 ff. Our choice of St. Augustine in the numerous contemporary scholarly attempted hermeneutics of 1 Cor 7:1–7 is that he adopts and elaborated an already existing tradition on sex and marriage. Moreover, this text in the New Testament is the only one that speaks explicitly of the (...) significance of conjugal intercourse. The interpretation of this text or passage has to an extent determined the development of the church’s tradition. Thus, the importance of the passage has to be considered. In Cor 7:1, Paul starts answering the questions the Corinthians put to him. Verse 1 reads: “Now concerning the matters about which you wrote”. The first of these questions concerns marriage. According to the superscription of this work, Augustine’s interpretation of 1 Cor 7:1–7 has implications for Christians in the contemporary world. In as much as it raises numerous problems to our contemporary understanding of marriage and sexuality, the problem of sexuality characterized our society today. (shrink)

To reduce the impact of floods, it is very important to identify and understand the socio-economic factors that determine people’s ability to cope with stress or change. Consequently, the study assesses the social vulnerability of the households to floods in Niger State, in order to provide the empirical evidence necessary for flood adaptation (...) policies and strategies in the state. The data for the research were obtained from the household survey and Dartmouth Flood Observatory. The data obtained were analysed using descriptive and statistical analysis. The results show that flood events in the study area were caused by heavy rainfall, compounded by the opening of the Shiroro dam gate to release the excess flood in the reservoir. Moreover, results of Student “t” test and One-Way Analysis of Variance on socio-economic characteristics show that households’ major economic activities, educational status, household size, income distribution, and membership of cooperative society were significant at p 10, do not belong to cooperative society and earn less that N21000 per month have higher mean frequency, thus, the predominant households were, therefore, farmers, illiterate, have large family size, poor, and have no access to loan. Thus, the socio-economic characteristics of the households in the study area contribute to their vulnerability to floods by reducing their coping capacity. Based on the results of the assessment, it is recommended that measures are taken to mainstream flood adaptation into the development process. (shrink)

Edward Pols long ago established himself as a philosopher of first rank. His carefully wrought studies have succeeded each other with regularity, The Recognition of Reason, Whitehead’s Metaphysics, Meditation on a Prisoner: Towards Understanding Action and Mind, and The Acts of Our Being: A Reflection on Agency and Responsibility. While clearly within a tradition that can be traced through modernity to the middle ages and to classical philosophy, Pols is no slave to the past. He recognizes the perennial character of (...) fundamental philosophical problems, their complexity, and the challenge they offer to the contemporary investigator. This perspicacity does not lead him to deny the worth of past efforts, but positions him to frame old problems in a new way. His insight is rooted in a profound grasp of the processes of human knowing and in a rare metaphysical sense. (shrink)

This paper addresses the past, present and future aspects of African leadership and organizational ethics that have, are and will be key for any organization to sustain its systems and structures. Organizational ethics revolves around written and/or unwritten guidelines, ethical values, principles, rules and standards, that are drawn from the harmonious coexistence with the biosphere and it is how these elements are applied that dictates the style of leadership and the ethical thinking of the leaders. Africa has a wide range (...) of complexities which are compounded by, inter alia, tribal divisiveness, selfish leadership, wealth inequality, and massive unemployment. Africans tend to draw their leadership and ethical practices and reflections from the events in the environment with which they have interacted for many years. However, in order to fully address and understand the African perspective in leadership and organizational ethics, a broad comprehension of the African diverse and complex landscape is needed through unravelling of the three dimensional existence of the people. African ethics, developed over time, unifies organizations and leadership since it is part of life and is practised, sub-consciously or unconsciously, by the people as they transform from one practice to the other, and during intergenerational transitions. Globalization, liberalization, technological changes and advancement, and market changes are rapidly transforming the environment in which organizations operate. In such a situation, an effective and true leader cannot be rigid but should be flexible, with the ability to use different leadership styles whenever the situation calls for it. Only those leaders with a three-dimensional perspective live inspiring lives, live with a cause and adopt organizational ethics and leadership styles that will stand the test of time. Despite Africa being the cradle of humankind, leadership and organizational ethics is still in its infancy and wanting, even with the new generation of young leaders. The future outlook of African organizational ethics and leadership is to be found in the intersection of changes in technology, life style, demographics and geopolitics with new trends emerging in global polity and economy.

The essays collected in this book discuss the contemporary pratice of corporate responsibility by applying the Christian principles of the unity of knowledge and pursuit of truth to the traditional principles of justice, human dignity and the common good, to rediscover a corporate culture that will help transform our economic system and the characteristics required to build an enduring trust in economic relationships. In this volume a select group of management theorists, theologians, legal scholars, economists and ethicists jointly strive to (...) give back to the market economy its ethical and political dimensions. They assess the quality of present day corporate social responsibility, discuss the social and environmental costs of production and argue for an agenda that can be used in modern corporations in their effort to align profitability and growth with business ethics.

In lieu of an abstract, here is a brief excerpt of the content:MARITAIN AS AN INTERPRETER OF AQUINAS ON THE PROBLEM OF INDIVIDUATION }UDE P. DOUGHERTY The Catholic University ofAmerica Washington, D.C. I T HE MEDIEVAL problem of individuation is not the contemporary problem of "individuals" or "particulars" discussed by P. F. Strawson, J. W. Meiland, and others.1 In a certain sense the problem of individuation originates with Parmenides, but it is Plato's philosophy of science that bequeaths the problem to (...) Aristotle and to his medieval commentators. Its solution in Aquinas is not that of Aristotle, nor is it that of Scotus or Suarez. Aquinas will distinguish between the problem of individuation and what we may call the problem of "individuality" or the problem of "subsistence." The solution to both will draw upon many Aristotelian distinctions but will incorporate key elements of St. Thomas's own metaphysics, including the real distinction between essence and existence and his doctrine of participation. It is Maritain's appropriation of St. Thomas's metaphysics that enables him to produce a realistic philosophy of science, one that he offers as compatible with contemporary scientific enquiry. It also enables him to develop a theory of person and personality. But the story begins with Plato. Although Plato's theory of knowledge may appear fanciful to the modern reader, his analysis of scientific knowledge contains a basic set of observations whose truth remains uncontested even 1 Cf. P.F. Strawson, Individuals: An Essay in Descriptive Metaphysics (London: Methuen and Co., 1959); J.W. Meiland, Talking About Particulars (New York: Humanities Press, 1970); P. Butchvarov, Resemblance and Identity (Bloomington: Indiana University Press, 1966). 19 20 JUDE P. DOUGHERTY though his explanation be faulty. Plato saw clearly that science is of the universal. Things may be particular, but when we consider them as objects of enquiry, the intellect focuses upon the form taken as an exemplar. In Plato's explanation things belong to their various kinds by participating in incorporeal, eternal, and unchangeable archetypes. From a realist's vantage point the problem may be stated simply: Since things are singular, how is it that we intellectually apprehend them as universal? Aristotle's solution is well known and it is one adopted and amplified by St. Thomas. Universals are abstracted from singular things. No one would present Maritain as a medievalist, but, as an interpreter of Aquinas, he has wielded considerable influence in the United States and in Latin America. Many have come to St. Thomas under his tutelage. His knowledge of Aquinas is extensive and is drawn upon throughout his lifelong work, but perhaps nowhere more than in his philosophy of science and in his discussions of the person. The primary text for Thomas's doctrine of individuation is his commentary on Boethius's De Trinitate, where he discusses the division and methods of the sciences. Maritain's philosophy is indebted mainly to his reading of Thomistic texts, but he draws heavily, as well, on the works of his contemporaries, Reginald Garrigou-Lagrange and Louis Geiger, and on those of the classic commentators on Thomas, Cajetan, Sylvester of Ferrara, and John of St. Thomas. Though employing St. Thomas, Maritain is always a man of the twentieth century. In books such as the Degrees of Knowledge, Science and Wisdom, Existence and the Existent, and A Preface to Metaphysics, his foe is always some contemporary exponent of a nominalist position.2 "Nominalists,'' he will say, "have a taste for the real, but no sense of being."3 Timeless 2 Degrees ofKnowledge [Les Degres du Savoir(l 932)], trans.

Nonverbal signals color the meanings of interpersonal relationships. Humans rely on facial, head, postural, and vocal signals to express relational messages along continua. Three of relevance are dominance-submission, composure-nervousness and trust-distrust. Machine learning and new automated analysis tools are making possible a deeper understanding of the dynamics of relational communication. These are explored in the context of group interactions during a game entailing deception. The “messiness” of studying communication under naturalistic conditions creates many measurement and design obstacles that are discussed (...) here. Possibilities for their mitigation are considered.

Corporate diversity initiatives have neither yielded higher financial returns for companies nor created significantly greater equity and equality of outcome for socially disadvantaged groups within organisations. There has been a systematic failure of diversity initiatives, as the strategic business importance of diversity has been avoided. Researchers argue that effective diversity management is dependent upon appropriate structures and systems, not upon human resource management training alone. This article discusses the impact of the design, introduction and application of the ‘Diversity Quality Cycle’. (...) This model allows for the embedding of the values of equality of opportunity and cultural diversity throughout core business functions, and for positive long-term change. A mixed-method approach was taken; Participative Action Research is the main methodology employed, within which quantitative data were generated, analysed and interpreted. The main case study organisation is a Further Education College in the West of England. (shrink)

Social relationships are constructed by and through the relational communication that people exchange. Relational messages are implicit nonverbal and verbal messages that signal how people regard one another and define their interpersonal relationships—equal or unequal, affectionate or hostile, inclusive or exclusive, similar or dissimilar, and so forth. Such signals can be measured automatically by the latest machine learning software tools and combined into meaningful factors that represent the socioemotional expressions that constitute relational messages between people. Relational messages operate continuously on (...) a parallel track with verbal communication, implicitly telling interactants the current state of their relationship and how to interpret the verbal messages being exchanged. We report an investigation that explored how group members signal these implicit messages through multimodal behaviors measured by sensor data and linked to the socioemotional cognitions interpreted as relational messages. By use of a modified Brunswikian lens model, we predicted perceived relational messages of dominance, affection, involvement, composure, similarity and trust from automatically measured kinesic, vocalic and linguistic indicators. The relational messages in turn predicted the veracity of group members. The Brunswikian Lens Model offers a way to connect objective behaviors exhibited by social actors to the emotions and cognitions being perceived by other interactants and linking those perceptions to social outcomes. This method can be used to ascertain what behaviors and/or perceptions are associated with judgments of an actor’s veracity. Computerized measurements of behaviors and perceptions can replace manual measurements, significantly expediting analysis and drilling down to micro-level measurement in a previously unavailable manner.

Dialogue is promoted by its supporters as a pluralising force capable of accommodating the moral disagreement inevitable in every sphere of human society, but this promise is widely and vehemently challenged. How are we to determine the principles upon which the dialogical exchange should take place? How should we think of ourselves as interlocutors? Should we associate dialogue with the desire for consensus? How should we determine decision-making? What are the gender dynamics of dialogical politics and how much do they (...) matter? This book brings together internationally recognised expert authors from the fields of political and social theory, political philosophy and international relations to consider these controversial questions anew from a range of theoretical positions. The differences of opinions and clashes of views make for a fascinating and highly informative read. (shrink)
