The formula A (it is noncontingent whether A) is true at a point in a Kripke model just in case all points accessible to that point agree on the truth-value of A. We can think of -based modal logic as a special case of what we call the general modal logic of agreement, interpreted with the aid of models supporting a ternary relation, S, say, with OA (which we write instead of A to emphasize the generalization involved) true at a (...) point w just in case for all points x, y, with Swxy, x and y agree on the truth-value of A. The noncontingency interpretation is the special case in which Swxy if and only if Rwx and Rwy, where R is a traditional binary accessibility relation. Another application, related to work of Lewis and von Kutschera, allows us to think of OA as saying that A is entirely about a certain subject matter. (shrink)

Several intrinsic/extrinsic distinctions amongst properties, current in the literature, are discussed and contrasted. The proponents of such distinctions tend to present them as competing, but it is suggested here that at least three of the relevant distinctions (including here that between non-relational and relational properties) arise out of separate perfectly legitimate intuitive considerations: though of course different proposed explications of the informal distinctions involved in any one case may well conflict. Special attention is paid to the question of whether a (...) single notion of property is capable of supporting the various distinctions. (shrink)

This text aims to convey some of the interest and charm of modal logic, and to put a reader new to the subject in a position to have an informed opinion as to its applicability to each of several areas of philosophical concern in which the merits of a modal approach' have been controversial. he main focus, for these purposes, is on normal modal logics, though some attention is given to the non-normal side of the picture.

It is observed that a consistent congruential modal logic is not guaranteed to have a consistent extension in which the Box operator becomes a truth-functional connective for one of the four one-place truth functions.

Business and society researchers, as well as practitioners, have been critiqued for ignoring those with less voice and power often referred to as “fringe stakeholders.” Existing methods used in B&S research often fail to address issues of meaningful participation, voice and power, especially in developing countries. In this article, we stress the utility of visual participatory research methods in B&S research to fill this gap. Through a case study on engaging Ghanaian cocoa farmers on gender inequality issues, we explore how (...) VPR methods may be used by researchers to achieve more inclusive, and thus more credible, stakeholder research that can improve decision making within businesses. Furthermore, we argue that ingrained social and environmental problems tackled by B&S research and the unique context in which they occur may open up new opportunities to develop participatory visual methods for social change.

Accounts of logical independence which coincide when applied in the case of classical logic diverge elsewhere, raising the question of what a satisfactory all-purpose account of logical independence might look like. ‘All-purpose’ here means: working satisfactorily as applied across different logics, taken as consequence relations. Principal candidate characterizations of independence relative to a consequence relation are that there the consequence relation concerned is determined by only by classes of valuations providing for all possible truth-value combinations for the formulas whose independence (...) is at issue, and that the consequence relation ‘says’ nothing special about how those formulas are related that it does not say about arbitrary formulas. Each of these proposals returns counterintuitive verdicts in certain cases—the truth-value inspired approach classifying certain cases one would like to describe as involving failures of independence as being cases of independence, and the de Jongh approach counting some intuitively independent pairs of formulas as not being independent after all. In final section, a modification of the latter approach is tentatively sketched to correct for these misclassifications. The attention is on conceptual clarification throughout, rather than the provision of technical results. Proofs, as well as further elaborations, are lodged in the ‘longer notes’ in a final Appendix.

We assemble material from the literature on matrix methodology for sentential logic—without claiming to present any new logical results—in order to show that Gödel once made (or at least, is quoted as having made) an uncharacteristically ill-considered remark in this area.

There is little doubt that Corporate Social Responsibility (CSR) is now a global concept and a prominent feature of international business, with its practice localised and differing across countries. Despite the growing body of research focussing on CSR in developing countries, there is dearth research on CSR institutionalisation in African countries. Drawing on institutional theory (IT), this article examines the focus and form of CSR practice of companies in Kenya. It is evident from our findings that the nature and orientation (...) of CSR differ across companies with operations only in Kenya and those headquartered abroad or with international operations. Significantly, firm-related drivers such as public relations and performance, as well as global institutional pressures explain the focus and form of CSR in Kenya. This article concludes that for the institutionalisation of CSR in Kenya, attention must be paid to conditions that stifle CSR uptake such as lack of government regulations, and the government's capacity and commitment to enforce regulation. The establishment of functional CSR institutions and a vibrant civil society that advance civil regulation ought to be encouraged. (shrink)

In _Sentient Flesh _R. A. Judy takes up freedman Tom Windham’s 1937 remark “we should have our liberty 'cause... us is human flesh" as a point of departure for an extended meditation on questions of the human, epistemology, and the historical ways in which the black being is understood. Drawing on numerous fields, from literary theory and musicology, to political theory and phenomenology, as well as Greek and Arabic philosophy, Judy engages literary texts and performative practices such as music and (...) dance that express knowledge and conceptions of humanity appositional to those grounding modern racialized capitalism. Operating as critiques of Western humanism, these practices and modes of being-in-the-world—which he theorizes as “thinking in disorder,” or “poiēsis in black”—foreground the irreducible concomitance of flesh, thinking, and personhood. As Judy demonstrates, recognizing this concomitance is central to finding a way past the destructive force of ontology that still holds us in thrall. Erudite and capacious, _Sentient Flesh _offers a major intervention in the black study of life. (shrink)

Recent advances in the brain sciences have dramatically improved our understanding of brain function. As we find out more and more about what makes us tick, we must stop and consider the ethical implications of this new found knowledge. Will having a new biology of the brain through imaging make us less responsible for our behavior and lose our free will? Should certain brain scan studies be disallowed on the basis of moral grounds? Why is the media so interested in (...) reporting results of brain imaging studies? What ethical lessons from the past can best inform the future of brain imaging? These compelling questions and many more are tackled by a distinguished group of contributors to this volume on neuroethics. The wide range of disciplinary backgrounds that the authors represent, from neuroscience, bioethics and philosophy, to law, social and health care policy, education, religion and film, allow for profoundly insightful and provocative answers to these questions, and open up the door to a host of new ones. The contributions highlight the timeliness of modern neuroethics today, and assure the longevity and importance of neuroethics for generations to come. (shrink)

After an introduction to set the stage, we consider some variations on the reasoning behind Curry's Paradox arising against the background of classical propositional logic and of BCI logic and one of its extensions, in the latter case treating the "paradoxicality" as a matter of nonconservative extension rather than outright inconsistency. A question about the relation of this extension and a differently described (though possibly identical) logic intermediate between BCI and BCK is raised in a final section, which closes with (...) a handful of questions left unanswered by our discussion.

The growing global prominence of Chinese state-owned enterprises brings new dimensions to our understanding of multi-national corporations and human rights issues. This article constructs a three-level framework that enables the mapping of transnational, national, and intra-organizational human rights pressures, and uses this framework to identify and analyze the human rights that Chinese SOEs report concern with. The analysis provided suggests that while China’s most global SOEs are subject to transnational pressures to respect all human rights, such pressures appear outweighed by (...) those encouraging them to concentrate on only some human rights within their national and intra-organizational environment. The article concludes by identifying a number of ways in which our conceptual framework and empirical findings can inform future research. (shrink)

Section 1 recalls a point noted by A. N. Prior forty years ago: that a certain formula in the language of a purely implicational intermediate logic investigated by R. A. Bull is unprovable in that logic but provable in the extension of the logic by the usual axioms for conjunction, once this connective is added to the language. Section 2 reminds us that every formula is interdeducible with (i.e. added to intuitionistic logic, yields the same intermediate logic as) some conjunction-free (...) formula. Thus it would seem that any detour going via formulas with conjunction can be avoided, which raises a puzzle: how is this consistent with the point from Section 1? Sections 3 and 4 raise and discuss this puzzle. In fact, the puzzle turns out on closer inspection not to be so puzzling after all, but it does serve as a convenient centrepiece around which to organize a discussion of the phenomenon illustrated by the Bull–Prior example. Section 5 notes that Prior's observation can be extended to the case of the result of adding disjunction to Bull's logic, while Section 6 includes some further remarks aimed at diagnosing one source of possible residual puzzlement. A subtext of our discussion—spanning several of the notes—is that this work by Bull and Prior has been overlooked, their results having to be rediscovered, by many algebraists and logicians in more recent years.

This study draws on Kohlberg''s Cognitive Moral Development Theory and Hofstede''s Culture Theory to examine whether cultural differences are associated with variations in ethical reasoning. Ethical reasoning levels for auditors from Australia and China are expected to be different since auditors from China and Australia are also different in terms of the cultural dimensions of long term orientation, power distance, uncertainty avoidance and individualism. The Defining Issues Tests measuring ethical reasoning P scores were distributed to auditors from Australia and China (...) including Hong Kong and The Chinese Mainland. Results show that auditors from Australia have higher ethical reasoning scores than those from China, consistent with Hofstede''s Culture Theory predictions. (shrink)

From a twenty-first century partnership between bioethics and neuroscience, the modern field of neuroethics is emerging, and technologies enabling functional neuroimaging with unprecedented sensitivity have brought new ethical, social and legal issues to the forefront. Some issues, akin to those surrounding modern genetics, raise critical questions regarding prediction of disease, privacy and identity. However, with new and still-evolving insights into our neurobiology and previously unquantifiable features of profoundly personal behaviors such as social attitude, value and moral agency, the difficulty of (...) carefully and properly interpreting the relationship between brain findings and our own self-concept is unprecedented. Therefore, while the ethics of genetics provides a legitimate starting point - even a backbone - for tackling ethical issues in neuroimaging, they do not suffice. Drawing on recent neuroimaging findings and their plausible real-world applications, we argue that interpretation of neuroimaging data is a key epistemological and ethical challenge. This challenge is two-fold. First, at the scientific level, the sheer complexity of neuroscience research poses challenges for integration of knowledge and meaningful interpretation of data. Second, at the social and cultural level, we find that interpretations of imaging studies are bound by cultural and anthropological frameworks. In particular, the introduction of concepts of self and personhood in neuroimaging illustrates the interaction of interpretation levels and is a major reason why ethical reflection on genetics will only partially help settle neuroethical issues. Indeed, ethical interpretation of such findings will necessitate not only traditional bioethical input but also a wider perspective on the construction of scientific knowledge. (shrink)

The point of the present paper is to draw attention to some interesting similarities, as well as differences, between the approaches to the logic of noncontingency of Evgeni Zolin and of Claudio Pizzi. Though neither of them refers to the work of the other, each is concerned with the definability of a (normally behaving, though not in general truth-implying) notion of necessity in terms of noncontingency, standard boolean connectives and additional but non-modal expressive resources. The notion of definability involved is (...) different in the two cases (‘external’ for Zolin, ‘internal’ for Pizzi), as are the additional resources: infinitary conjunction in the case of Zolin, and for Pizzi, first, propositional quantification, and then, later, most ingeniously, the use of a propositional constant. As well as surveying and comparing of the work of these authors, the discussion includes some some novelties, such as the confirmation of a conjecture of Zolin’s (Theorem 2.7). (shrink)

This paper reviews major structural drivers of place-based health disparities in the context of Canada, an industrialized nation with a strong public health system. Likelihood that the COVID-19 pandemic will facilitate rejuvenation of Canada’s northern and remote areas through remote working, advances in online teaching and learning, and the increased use of telemedicine are also examined. The paper concludes by identifying some common themes to address healthcare disparities for northern and remote Canadian residents.

Benjamin Libet has argued that electrophysiological signs of cortical movement preparation are present before people report having made a conscious decision to move, and that these signs constitute evidence that voluntary movements are initiated unconsciously. This controversial conclusion depends critically on the assumption that the electrophysiological signs recorded by Libet, Gleason, Wright, and Pearl are associated only with preparation for movement. We tested that assumption by comparing the electrophysiological signs before a decision to move with signs present before a decision (...) not to move. There was no evidence of stronger electrophysiological signs before a decision to move than before a decision not to move, so these signs clearly are not specific to movement preparation. We conclude that Libet’s results do not provide evidence that voluntary movements are initiated unconsciously. (shrink)

The idea that our conscious decisions determine our actions has been challenged by a report suggesting that the brain starts to prepare for a movement before the person concerned has consciously decided to move . Libet et al. claimed that their results show that our actions are not consciously initiated. The current article describes two experiments in which we attempted to replicate Libet et al.'s comparison of participants' movement-related brain activity with the reported times of their decisions to move and (...) also the reported times of their decisions of which hand to move. We also looked at the distribution of participants' reports over time to evaluate an alternative explanation of Libet et al.'s results. Although the Readiness Potential was usually present before all of the decisions to move, consistent with the findings of Keller and Heckhausen and Libet et al. , we found that many reported decision times were before the onset of the Lateralized Readiness Potential, which measures hand-specific movement preparation. The latter finding is consistent with the conclusion that the LRP always started after the conscious decision to move. We conclude that even though activity related to movement anticipation may be present before a conscious decision to move, the cortical preparation necessary for the movement to happen immediately may not start until after the conscious decision to move.

The idea of a property's being supervenient on a class of properties is familiar from much philosophical literature. We give this idea a linguistic turn by converting it into the idea of a predicate symbol's being supervenient on a set of predicate symbols relative to a (first order) theory. What this means is that according to the theory, any individuals differing in respect to whether the given predicate applies to them also differ in respect to the application of at least (...) one of the predicates in the set. The latter relationship we show turns out to coincide with something antecedently familiar from work on definability: with what is called the piecewise (or modelwise) definability, in the theory in question, of the given predicate in terms of those in the set.

Jean-Yves Béziau (‘Classical Negation can be Expressed by One of its Halves’, Logic Journal of the IGPL 7 (1999), 145–151) has given an especially clear example of a phenomenon he considers a sufficiently puzzling to call the ‘paradox of translation’: the existence of pairs of logics, one logic being strictly weaker than another and yet such that the stronger logic can be embedded within it under a faithful translation. We elaborate on Béziau’s example, which concerns classical negation, as well as (...) giving some additional background (especially from intuitionistic logic) to the example. Our interest is more on the logical exploration of the phenomenon Béziau’s case exemplifies than on the question of whether that phenomenon is (even prima facie ) paradoxical, though in Section 5 we do approach the latter question – somewhat obliquely – by considering an analogous phenomenon which it is hard to find puzzling.

Was there such a person as Lewis Carroll? An affirmative answer is suggested by the thought that Lewis Carroll was Charles Dodgson, and since there was certainly such a person as Charles Dodgson, there was such a person as Lewis Carroll. A negative answer is suggested by the thought that in arguing thus, the two names ‘Lewis Carroll’ and ‘Charles Dodgson’ are being inappropriately treated as though they were completely on a par: a pseudonym is, after all, a false or (...) fictitious name. Perhaps we should say instead that there was really no such person as Lewis Carroll, but that when Charles Dodgson published under that name, he was pretending that there was, and further, pretending that the works in question formed part of the literary output of this pretendedly real individual. Whether or not this is correct for the case of ‘Lewis Carroll’, I will be suggesting that an account of this second style–a fictionalist account, for short–is appropriate for at least a good many pseudonyms. We shall get to reasons why it might nonetheless not be especially appropriate in the present case in due course: one advantage of the ‘Lewis Carroll’/‘Charles Dodgson’ example, such qualms notwithstanding, is that everyone is familiar not only with both names but with which of them is the pseudonym. Another is that, as we shall have occasion to observe below, Dodgson himself had some interesting views on this particular case of pseudonymy. (shrink)

The garish glow of neon was part of what put Las Vegas on the map—quite literally. The city’s most distinctive form of expression, neon signs tell an elaborate story of the history of Las Vegas, from their debut in 1929 at the onset of the Depression, when their seductive tones lured travelers through the Mojave Desert to part with scarce dollars, to today, when their flickering glow is a vanishing facet of the gaudy spectacle that is contemporary Vegas. Established in (...) 1996 to preserve Las Vegas’s underappreciated neon heritage, the Neon Boneyard houses many of the city's historic casino signs on a three-acre site at the edge of the city. The core of the collection of unrestored signage came from the pioneering Young Electric Sign Company, one of the first to produce neon signs in the area; but, in recent years, it has grown through donations from businesses and individuals who appreciate the key role played by neon in the growth of Las Vegas. Through Judy Natal’s photographs, the Neon Boneyard becomes a dynamic archaeological site that brings Vegas’s past to life in startling ways. The towering figure of Mr. O’Lucky becomes a home for the homeless, while the crumpled sign of a wedding chapel reflects the faded dreams of a lost paradise. Through such juxtapositions of success and failure, of past and present, Neon Boneyard: Las Vegas A–Z returns us to an earlier image of Vegas, suffused with the warm, commercial glow of neon, lighting the desert and inventing modern nightlife.

In this article we explore the role of data custodians in establishing and maintaining social licence for the use of personal information in health research. Personal information from population‐level data collections can be used to make significant contributions to health and medical research, but this use is dependent on community acceptance or a social licence. We conducted semi‐structured interviews with data custodians across Australia to better understand data custodians’ views on their roles and responsibilities. This inductive, thematic analysis of the (...) interview data focuses on three factors that contribute to social licence – reciprocity, non‐exploitation and the public good. While the data custodians interviewed did not explicitly frame their role in the context of social licence, their descriptions of their roles and responsibilities clearly indicated that they did have some role to play in building and maintaining social licence.

This paper assembles examples and considerations bearing on such questions as the following. Are statements to the effect that someone is too young or that someone is old enough always to be understood in terms of someone's being too young or too old for such-and-such-for example, for them to join a particular organization? And when a 'such-and-such' has been specified, is it always at least tacitly modal in force-in the case just given, too young or old enough to be able (...) to join the organization? These questions are explored by means of a critical examination of the answers given to them by Eric Nelson in a 1980 paper on the subject, with part of the intention being to rescue Nelson's thoughtful discussion from the oblivion into which it appears to have fallen, judging by more recent contributions on the subject by semanticists.

A 1-ary sentential context is aggregative (according to a consequence relation) if the result of putting the conjunction of two formulas into the context is a consequence (by that relation) of the results of putting first the one formula and then the other into that context. All 1-ary contexts are aggregative according to the consequence relation of classical propositional logic (though not, for example, according to the consequence relation of intuitionistic propositional logic), and here we explore the extent of this (...) phenomenon, generalized to having arbitrary connectives playing the role of conjunction; among intermediate logics, LC, shows itself to occupy a crucial position in this regard, and to suggest a characterization, applicable to a broader range of consequence relations, in terms of a variant of the notion of idempotence we shall call componentiality. This is an analogue, for the consequence relations of propositional logic, of the notion of a conservative operation in universal algebra. (shrink)

Biobanks for long-term research pose challenges to the legal and ethical validity of consent to participate. Different models of consent have been proposed to answer some of these challenges. This paper contributes to this discussion by considering the meaning and value of consent to participants in biobanks. Empirical data from a qualitative study is used to provide a participant view of the consent process and to demonstrate that, despite limited understanding of the research, consent provides the research participants with some (...) level of control and a form of self determination that they value. Participation is framed as a moral act of a responsible citizen providing reinforcement of self identity. Consent symbolizes the trust invested in researchers and research institutions to use the biobank for the public good. The paper argues that consent continues to play an important role in biobank participation and that a participant view should inform proposals to modify consent processes. (shrink)

Matthew Spinks [35] introduces implicative BCSK-algebras, expanding implicative BCK-algebras with an additional binary operation. Subdirectly irreducible implicative BCSK-algebras can be viewed as flat posets with two operations coinciding only in the 1- and 2-element cases, each, in the latter case, giving the two-valued implication truth-function. We introduce the resulting logic (for the general case) in terms of matrix methodology in §1, showing how to reformulate the matrix semantics as a Kripke-style possible worlds semantics, thereby displaying the distinction between the two (...) implications in the more familiar language of modal logic. In §§2 and 3 we study, from this perspective, the fragments obtained by taking the two implications separately, and – after a digression (in §4) on the intuitionistic analogue of the material in §3 – consider them together in §5, closing with a discussion in §6 of issues in the theory of logical rules. Some material is treated in three appendices to prevent §§1–6 from becoming overly distended. (shrink)

The potential for conceptualizing unethical organizational behavior as (...) multidimensional is discussed. (shrink)
