This study investigates the likelihood of director turnover following opportunistic insider selling. Given that opportunistic insider selling may be costly to a firm due to potential legal risk and firm legitimacy concerns, we hypothesize that directors engaging in this type of transactions have a higher likelihood of subsequently leaving the board. Using archival data of 11,409 directors in 2280 US firms from 2005 to 2014, univariate comparisons show that directors engaging in opportunistic insider selling are about 8% more likely to (...) exit their firms’ board compared to directors not engaging in this behavior. Furthermore, multivariate results show that the likelihood of director departure following opportunistic insider selling is higher for some directors but not all. Specifically, directors who are especially valuable to the board or costly to replace do not seem to experience elevated levels of turnover. Interestingly, this difference in director turnover is only observed in smaller firms. We find that in larger firms, the likelihood of director turnover following opportunistic insider selling does not depend on director characteristics. As such, results seem to suggest that boards do not homogeneously self-regulate in this context as some directors seem to be shielded from turnover following unethical behavior. (shrink)

We introduce non-associative linear logic, which may be seen as the classical version of the non-associative Lambek calculus. We define its sequent calculus, its theory of proof-nets, for which we give a correctness criterion and a sequentialization theorem, and we show proof search in it is polynomial.

A social scientific survey on visions of human/nature relationships in western Europe shows that the public clearly distinguishes not only between anthropocentrism and ecocentrism, but also between two nonanthropocentric types of thought, which may be called “partnership with nature” and “participation in nature.” In addition, the respondents distinguish a form of human/nature relationship that is allied to traditional stewardship but has a more ecocentric content, labeled here as “guardianship of nature.” Further analysis shows that the general public does not subscribe (...) to an ethic of “mastery over nature.” Instead, practically all respondents embrace the image of guardianship, while the more radical relationships of partnership and participation also received significant levels of adherence. The results imply that ethicists should no longer assume that the ethics of the public are merely anthropocentric. Finally, they call into question the idea of a single form of ecocentrism and favor a hermeneutic virtue ethics approach to the study of the interface between ethics and action. (shrink)

De relevantie van Beccaria voor het Nederlandse strafrecht: het beïnvloedingsprincipe Aan de hand van dit artikel wordt onderzocht in hoeverre Beccaria’s ideeën nog steeds relevant zijn voor het Nederlandse strafrecht. Een essentieel punt in zijn filosofie is gedragsbeïnvloeding. Beccaria hecht veel waarde aan het codificeren en kenbaar maken van (duidelijk opgestelde) wetten. Hierdoor weten burgers welke gedragingen strafbaar zijn gesteld en worden – zo is de veronderstelling van hem – door die strafrechtelijke kennis beïnvloed strafbaar gedrag achterwege te laten. Daarnaast (...) moet volgens Beccaria het opleggen van een straf als doel hebben het gedrag te beïnvloeden, niet alleen zodat de dader opnieuw de fout ingaat (speciale preventie), maar ook dat anderen worden beïnvloed het gedrag achterwege te laten (generale preventie). In dit artikel wordt dit gedragsbeïnvloedingsidee het ‘beïnvloedingsprincipe’ genoemd en biedt een nieuw perspectief op de filosofie van Beccaria. Ook wordt met behulp van dit principe een analyse gemaakt van (de functie van) het hedendaagse legaliteitsbeginsel en de wijze waarop er wordt gestraft. Uit deze analyse zal blijken dat het beïnvloedingsprincipe nog steeds relevant is voor hedendaagse discussies. (shrink)

Genomic data is generated, processed and analysed at an increasingly rapid pace. This data is not limited to the medical context, but plays an important role in other contexts in society, such as commercial DNA testing, the forensic setting, archaeological research, and genetic surveillance. Genomic information also crosses the borders of these domains, e.g. forensic use of medical genetic information, insurance use of medical genomic information, or research use of commercial genomic data. This paper (1) argues that an informed consent (...) approach for genomic information has limitations in many societal contexts, and (2) seeks to broaden the bioethical debate on genomic information by suggesting an approach that is applicable across multiple societal contexts. I argue that the contextual integrity framework, a theory rooted in information technology and big data ethics, is an effective tool to explore ethical challenges that arise from genomic information within a variety of different contexts. Rather than focusing on individual control over information, the contextual integrity approach holds that information should be shared and protected according to the norms that govern certain distinct social contexts. Several advantages of this contextual integrity approach will be discussed. The paper concludes that the contextual integrity framework helps to articulate and address a broad spectrum of ethical, social, and political factors in a variety of different societal contexts, while giving consideration to the interests of individuals, groups, and society at large.

We consider subintuitionistic logics as an extension of positive propositional logic with a binary modality, interpreted over ordered and unordered monotone neighborhood frames, with a range of frame conditions. This change in perspective allows us to apply tools and techniques from the modal setting to subintuitionistic logics. We provide a Priestley-style duality, and transfer results from the (classical) logic of monotone neighborhood frames to obtain completeness, conservativity, and a finite model property for the basic logic, extended with a number of (...) axioms.

BackgroundThis article is part of a study to gain insight into the decision-making process by looking at the views of the relatives of potential brain dead donors. Alongside a literature review, focus interviews were held with healthcare professionals about their role in the request and decision-making process when post-mortal donation is at stake. This article describes the perspectives of the relatives.MethodsA content-analysis of 22 semi-structured in-depth interviews with relatives involved in an organ donation decision.ResultsThree themes were identified: ‘conditions’, ‘ethical considerations’ (...) and ‘look back’. Conditions were: ‘sense of urgency’, ‘incompetence to decide’ and ‘agreement between relatives’. Ethical considerations result in a dilemma for non-donor families: aiding people or protecting the deceased’s body, especially when they do not know his/her preference. Donor families respect the deceased’s last will, generally confirmed in the National Donor Register. Looking back, the majority of non-donor families resolved their dilemma by justifying their decision with external arguments. Some non-donor families would like to be supported during decision-making.DiscussionThe discrepancy between general willingness to donate and the actual refusal of a donation request can be explained by multiple factors, with a cumulative effect. Firstly, half of the participants stated that they felt that they were not competent to decide in such a crisis and they seem to struggle with utilitarian considerations against their wish to protect the body. Secondly, non-donor families refused telling that they did not know the deceased’s wishes or contesting posthumous autonomy of the eligible. Thirdly, the findings emphasise the importance of Donor Registration, because it seems to prevent dilemmas in decision-making, at least for donor families.ConclusionDiscrepancies between willingness to consent to donate and refusal at the bedside can be attributed to an unresolved dilemma: aiding people or protect the body of the deceased. Non-donor families felt incompetent to decide. They refused consent for donation, since their deceased had not given any directive. When ethical considerations do not lead to an unambiguous answer, situational factors were pivotal. Relatives of unregistered eligible donors are more prone to unstable decisions. To overcome ambivalence, coaching during decision-making is worth investigation. (shrink)

Millions of human biological samples are stored worldwide for medical research or treatment purposes. These biospecimens are of enormous potential value to law enforcement as DNA profiles can be obtained from these samples. However, forensic use of such biospecimens raises a number of ethical questions. This article aims to explore ethical issues of using human bodily material in medical biobanks for crime investigation and prosecution purposes. Concerns about confidentiality, trust, autonomy and justice will be discussed. We explore how to balance (...) these concerns against the importance of crime solving. Relevant case examples of forensic use of medical biobanks show that requests by law enforcement to access biobanks are handled in disparate ways. We identify some core ethical issues and conclude that further research on these issues is needed to provide ethical guidance. (shrink)

In the Netherlands, consent from relatives is obligatory for post mortal donation. This study explored the perspectives of relatives regarding the request for consent for donation in cases without donor registration. A content analysis of narratives of 24 bereaved relatives of unregistered, eligible, brain-dead donors was performed. Relatives of unregistered, brain-dead patients usually refuse consent for donation, even if they harbour pro-donation attitudes themselves, or knew that the deceased favoured organ donation. Half of those who refused consent for donation mentioned (...) afterwards that it could have been an option. The decision not to consent to donation is attributed to contextual factors, such as feeling overwhelmed by the notification of death immediately followed by the request; not being accustomed to speaking about death; inadequate support from other relatives or healthcare professionals, and lengthy procedures. Healthcare professionals could provide better support to relatives prior to donation requests, address their informational needs and adapt their message to individual circumstances. It is anticipated that the number of consenting families could be enlarged by examining the experience of decoupling and offering the possibility of consent for donation after circulatory death if families refuse consent for donation after brain-death.

This paper examines geometrical arguments from Galileo's Mechanics and Two New Sciences to discern the influence of the Aristotelian Mechanical Problems on Galileo's dynamics. A common scientific procedure is found in the Aristotelian author's treatment of the balance and lever and in Galileo's rules concerning motion along inclined planes. This scientific procedure is understood as a development of Eudoxan proportional reasoning, as it was used in Eudoxan astronomy rather than simply as it appears in Euclid's Elements. Topics treated include the (...) significance of the circle in Galileo's demonstrations, the substitution of rectilinear elements for heterogeneous factors like weight and curvilinear distance, and the way in which elements of a motion are used to measure other elements of the same motion. The indirectness of Galileo's proofs, his conception of speed as relative and comparative, and the meaning of his concept of moment all come into clearer focus. Conclusions are drawn about Galilean idealization, and also about the contrast of literal versus figural modes of explanation in Galileo's science. (shrink)

With its focus on philosophy of nature, this book fills a gap in the ongoing reassessment of nineteenth-century American philosophy, and it opens the way to further study of the role played by reflection on nature in the emergence of the American mind.

Modern commentators have doubts about the authenticity and cogency of the early propositions of Archimedes’ On Equilibrium of Planes Book 1. Ernst Mach famously said that the proof of Prop. 6, the so-called law of the lever, assumes what is to be proven. Comparing the initial text in Heiberg’s modern edition (1881, 1913) to the first propositions in Eutocius’ commentary on EP 1, J. L. Berggren ([1976]. ‘Spurious Theorems in Archimedes’ Equilibrium of Planes: Book I’, Archive for History of Exact (...) Sciences 16.2 (1976), 87–103.) claimed that the propositions up through Proposition 3 of the standard modern edition are schoolbook additions written by an ancient author inferior to Archimedes. The present paper argues for the logical connectedness of Postulates 1–5 to Props. 1–6, by means of a detailed examination of the course of the argument and a re-examination of Eutocius’ remarks. The paper reinterprets the role of the empirical in the early propositions and offers a reading of the contribution of Archimedes’ mechanics to the method of EP 1. (shrink)

This paper proposes communities of practice (CoP) as a process to build moral resilience in healthcare settings. We introduce the starting point of moral distress that arises from ethical challenges when actions of the healthcare professional are constrained. We examine how situations such as the current COVID-19 pandemic can exponentially increase moral distress in healthcare professionals. Then, we explore how moral resilience can help cope with moral distress. We propose the term collective moral resilience to capture the shared capacity arising (...) from mutual engagement and dialogue in group settings, towards responding to individual moral distress and towards building an ethical practice environment. Finally, we look at CoPs in healthcare and explore how these group experiences can be used to build collective moral resilience. (shrink)

Im Jahre 1886 erregte I. Hilberg großes Aufsehen, als er in einem Artikel über die Autorschaft des Christus patiens auf die verschiedene Behandlung der dichrona bei den Jambographen der byzantinischen Epoche hinwies – die bis heute herrschende Anschauung geht dahin, dass α, ι und υ bei den byzantinischen Jambographen ausnahmslos mittelzeitig sind – und, je nach der absoluten Korrektheit in der Versifikation, sowohl was die Quantität als was die Zäsuren betraf, die Autoren in drei Gruppen meinte einreihen zu können: die (...) Classiker, die Epigonen und die Stümper. P. Maas griff diesen Standpunkt quasi unmittelbar an; er bemerkte sarkastisch, dass in diesem Fall Georgios Pisides, umstrahlt von der Glorie reinster Quantität einsam über allen anderen Dichtern in der einsamen Höhe seines „klassischen“ Himmels thronen würde, und dass die Byzantiner in Wirklichkeit von der Quantität der Vokale nichts hörten, da dieselben einfach isochron geworden waren. Dies hat nicht verhindert, dass F. Scheidweiler lange danach doch untersucht hat, ob die Poesie des Joannes Geometres noch der antiken Quantitätslehre entspricht, oder konkreter: dem Metrum des jambischen Trimeters:In diesem Beitrag möchte ich, mit den Untersuchungen von Scheidweiler als Richtschnur, der Frage nachgehen, in welchem Maβe der Dichter in seiner Μετάφϱασις των ώδων tatsächlich noch die antike Metrik respektiert.

Over 30 million people worldwide have taken a commercial at-home DNA test, because they were interested in their genetic ancestry, disease predisposition or inherited traits. Yet, these consumer DNA data are also increasingly used for a very different purpose: to identify suspects in criminal investigations. By matching a suspect’s DNA with DNA from a suspect’s distant relatives who have taken a commercial at-home DNA test, law enforcement can zero in on a perpetrator. Such forensic use of consumer DNA data has (...) been performed in over 200 criminal investigations. However, this practice of so-called investigative genetic genealogy raises ethical concerns. In this paper, we aim to broaden the bioethical analysis on IGG by showing the limitations of an individual-based model. We discuss two concerns central in the debate: privacy and informed consent. However, we argue that IGG raises pressing ethical concerns that extend beyond these individual-focused issues. The very nature of the genetic information entails that relatives may also be affected by the individual customer’s choices. In this respect, we explore to what extent the ethical approach in the biomedical genetic context on consent and consequences for relatives can be helpful for the debate on IGG. We argue that an individual-based model has significant limitations in an IGG context. The ethical debate is further complicated by the international, transgenerational and commercial nature of IGG. We conclude that IGG should not only be approached as an individual but also—and perhaps primarily—as a collective issue. There are no data in this work. (shrink)

In _Aristotle’s Empiricism_, Jean De Groot argues that an important part of Aristotle’s natural philosophy has remained largely unexplored and shows that much of Aristotle’s analysis of natural movement is influenced by the logic and concepts of mathematical mechanics that emerged from late Pythagorean thought. De Groot draws upon the pseudo-Aristotelian_ Physical Problems_ XVI to reconstruct the context of mechanics in Aristotle’s time and to trace the development of kinematic thinking from Archytas to the Aristotelian _Mechanics_. She shows the influence (...) of kinematic thinking on Aristotle’s concept of power or potentiality, which she sees as having a physicalistic meaning originating in the problem of movement. De Groot identifies the source of early mechanical knowledge in kinesthetic awareness of mechanical advantage, showing the relation of Aristotle’s empiricism to more ancient experience. The book sheds light on the classical Greek understanding of imitation and device, as it questions both the claim that Aristotle’s natural philosophy codifies opinions held by convention and the view that the cogency of his scientific ideas depends on metaphysics.

El desafío actual de la posverdad que amenaza el funcionamiento de la democracia surge desde los límitesde nuestro conocimiento y la interferencia de las emociones y los valores. Dos corrientes comunes, la ética del discurso, y la política agonista, son insuficientes para resolver este desafío. En la comprensión de la política de Aristóteles estos dos elementos ya estaban presentes. Él presenta a la política como un campo de saber determinado no exclusivamente por el saber, sino al mismo tiempo por los (...) límites del saber y por el cargo emotivo.El objetivo de este artículo es proponer una concepción contemporánea de un discurso político phronético,incorporando las características clave de una phronesis aristotélica. La hipótesis es que un discurso políticophronético contemporáneo no se puede fundar en el bien, ya que la pluralidad de las concepciones del bien es lo que separa la política moderna de los tiempos aristotélicos. En su lugar, y siguiendo a los debates en la ética neo-aristotélica, se debería buscar el fundamento en el desarrollo del carácter de los (futuros) participantes en dicho discurso. Por consiguiente, la educación es el punto de partida esencial para reforzar las capacidades y los hábitos de los participantes del discurso a fin de mejor manejar, en la medida de lo posible, las limitaciones de nuestro conocimiento y nuestro compromiso personal con el campo político.

Originally published in 1991. Philoponus’ long commentary on Aristotle’s definition of light sets up the major concerns, both in optics and theory of light, that is discussed here. Light was of special interest in Neoplatonism because of its being something incorporeal in the world of natural bodies and therefore had a special role in the philosophical analysis of the interpenetration of bodies and also as a paradigm for the soul-body problem. The material investigated in this book contains much about the (...) physiology of vision as well as the propagation of light. Several chapters investigate the philosophical theory and its origins in ‘multiplication of species.’ These issues in the history of science philosophy are looked at further and an analysis is offered of the development of the distinction between Aristotle’s kinesis and energeia. The book covers a substantial amount of the philosophy of mathematical science from the point of view of Philoponus, drawing on more of his works relating to three dimensionality. (shrink)

Many studies claim to measure decision-making under risk by employing the Domain-Specific Risk-Taking (DOSPERT) scale, a self-report measure, or the Balloon Analogue Risk Task (BART), a behavioural task. However, these tasks do not measure decision-making under risk but decision-making under uncertainty, a related but distinct concept. The present commentary discusses both the theoretical and empirical basis of the distinction between uncertainty and risk from the viewpoint of several scientific disciplines and reports how many studies wrongfully employ the DOSPERT scale and (...) BART as risk-taking measures. Importantly, we call for proper distinguishing between (tasks measuring) decision-making under uncertainty and decision-making under risk in psychology and related fields. We believe this is vital as research has shown that people’s attitudes, behaviour, and brain activity differ between both concepts, indicating that confusing the concepts may lead researchers to erroneous conclusions.

Positive monotone modal logic is the negation- and implication-free fragment of monotone modal logic, i.e., the fragment with connectives and. We axiomatise positive monotone modal logic, give monotone neighbourhood semantics based on posets, and prove soundness and completeness. The latter follows from the main result of this paper: a duality between so-called \-spaces and the algebraic semantics of positive monotone modal logic. The main technical tool is the use of coalgebra.

International treaties, conventions and declarations have been developed in an attempt to establish a world in which people s basic rights and needs are provided for. An increasing number of states have ratified and incorporated them into their national legislations. But are such norms and values truly universal? And with states no longer being the only actors that shape global developments, what can be said about the role of social contracts between state and society for shaping the agenda of international (...) cooperation? And how do these social contracts develop in heterogeneous societies? If people themselves are the main drivers behind development, what does this imply for foreign aid?These and other questions are addressed in "Global Values in a Changing World," the 2010-2011 lecture series organized by the Netherlands Chapter of the Society for International Development. This volume combines views and recommendations by international experts, academics, and activists, and analyzes the connection between internationally agreed norms, standards, goals, and common goods, and the way they can be realized in a world that is both globalized and localized.".

In the introduction to An Approach to Aristotle’s Physics, David Bolotin presents an exceptionally clear account of the difficulties of making a claim for Aristotle’s natural philosophy as a contemporary teacher about nature. Modern science has repudiated the chief elements of the Aristotelian cosmos—the geocentric universe, the account of projectile motion—and so the contemporary interpreter treats Aristotle as a brilliant expositor of the world “as it appears.” Alternatively, the interpreter may say there is no final truth in the matter of (...) nature, so Aristotle’s cosmos within its own perspective was as compelling as our modern science is within its own perspective. Neither of these interpretations suits Aristotle, Bolotin says, since the philosopher’s conception of science included its being a true account of nature itself. (shrink)

It is shown that Aristotle’s references to automata in his biological treatises are meant to invoke the principle behind the ancient conception of the lever, i.e. that points on the rotating radius of a circle all move at different speeds proportional to their distances from the center. This principle is mathematical and explains a phenomenon taken as whole. Automata do not signify for him primarily a succession of material movers in contact, the modern model for mechanism. For animal locomotion and (...) embryological development, Aristotle models his dunamis concept on the idea of mechanical potential that the lever principle displays. (shrink)

Este texto pretende apresentar reflexões acerca do pensamento em constelação proposto por Adorno para problematizar as práticas formativas colocadas em movimento nos contextos educativos. Para tanto, nos utilizamos da pesquisa bibliográfica para pensar criticamente sobre a formação dos sujeitos nos contextos educativos. Inspirados no pensamento adorniano nos reportamos ao conceito de constelação e, posteriormente, às categorias de emancipação e autorreflexão. As problematizações construídas nesse trabalho podem contribuir para o desvelamento da multiplicidade de questões que envolvem a complexidade do campo educativo (...) e dos sujeitos que ali se constituem. Indicam a necessidade de compreender que um conceito se entrelaça com outros conceitos, que ultrapassa a linearidade e a busca de um ponto de chegada. Nessa direção, é imprescindível redimensionar os processos de formação docente, ampliando as perspectivas de formação e promovendo experiências de autorreflexão da própria razão.
