When cells are starved of their substrate, many nutrient transporters are induced. These undergo rapid endocytosis and redirection of their intracellular trafficking when their substrate becomes available again. The discovery that some of these transporters also act as receptors, or transceptors, suggests that at least part of the sophisticated controls governing the trafficking of these proteins has to do with their signaling function rather than with control of transport. In yeast, the general amino acid permease Gap1 mediates signaling to the (...) protein kinase A pathway. Its endocytic internalization and intracellular trafficking are subject to amino acid control. Other nutrient transceptors controlling this signal transduction pathway appear to be subject to similar trafficking regulation. Transporters with complex regulatory control have also been suggested to function as transceptors in other organisms. Hence, precise regulation of intracellular trafficking in nutrient transporters may be related to the need for tight control of nutrient‐induced signaling. (shrink)

Several attempts to conceptualize farm animal welfare have been criticized for diverging reasons, among them often the failure to incorporate the public concern and opinion. This paper’s objective is to develop a conception of farm animal welfare that starts from the public’s perception and integrates the opinion of different stakeholder representatives, thus following a fork-to-farm approach. Four qualitative citizen focus group discussions were used to develop a quantitative questionnaire, which has been completed by a representative sample of Flemish citizens ( (...) n = 459). Exploratory and confirmatory factor analyses were applied to develop a conception of farm animal welfare starting from an extended list of aspects that relate to animal production and associate with farm animal welfare in the public’s perception. In depth interviews with stakeholder representatives were used to match and adapt the structure of the animal welfare conception model. The resulting conception revealed seven dimensions grouped in two different levels. Three dimensions were animal-based: “Suffering and Stress,” “Ability to Engage in Natural Behavior,” and “Animal Health.” Four dimensions were resource-based: “Housing and Barn climate,” “Transport and Slaughter,” “Feed and Water,” and “Human-Animal Relationship.” This conception is distinct from earlier attempts since it is based on public perceptions; it addresses the opinion of different stakeholders, and it distinguishes empirically between animal-based and resource-based dimensions in the conceptualization of farm animal welfare. The relevancy of a popular definition is supported by the present demand oriented economy, in which animal welfare is a non-trade concern, and mainly left to the market where consumers still mainly act as individuals who calculate and weigh pros and cons.

Traces of and tracks towards philosophy and philosophizing in Flemish secondary education At present philosophy has only a minor place in the Flemish secondary education curriculum. In the first part of the article, I defend the view that philosophy deserves a place as an autonomous subject in the final two years of secondary school. I sketch the content of such a philosophy course and I propose a didactical model for this course. The second part of the article discusses social tendencies (...) that explain the current debate over whether there should be more philosophy in secondary schools. In the third part I try to explain why philosophy still lacks a structural place in Flemish secondary education. Finally I present a survey of ‘traces’ of philosophy and philosophizing in Flemish secondary education and I formulate a conclusion. (shrink)

When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint and technological progress can create moral progress rather than just moral problems. We show this by (...) an analysis of how technology can contribute to the solution of so-called moral overload or moral dilemmas. Such dilemmas typically create a moral residue that is the basis of a second-order principle that tells us to reshape the world so that we can meet all our moral obligations. We can do so, among other things, through guided technological innovation. (shrink)

Three puzzles about self-deception make this mental phenomenon an intriguing explanatory target. The first relates to how to define it without paradox; the second is about how to make sense of self-deception in light of the interpretive view of the mental that has become widespread in philosophy; and the third concerns why it exists at all. In this paper I address the first and third puzzles. First, I define self-deception. Second, I criticize Robert Trivers' attempt to use adaptionist evolutionary psychology (...) to solve the third puzzle (existence). Third, I sketch a theory to replace that of Trivers. Self-deception is not an adaptation, but a spandrel in the sense that Gould and Lewontin give the term: a byproduct of other features of human (cognitive) architecture. Self-deception is so undeniable a fact of human life that if anyone tried to deny its existence, the proper response would be to accuse this person of it. (Allen Wood, 1988). (shrink)

According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, (...) and only sustained empirical research in cognitive science will determine the extent to which that is true. (shrink)

I analyze three forms of the slippery slope argument (two logical and one empirical) using two questions: 1) in the context of what kind of norms are we considering a first step on a possible slope: statute law, precedent law, positive morality, or critical morality? 2) What is meant by "If we allow this first step"? The conclusion is that the argument's greatest force is in a context of institutionalized norms, like law, whereas its importance in morality is only marginal.

Nagel’s official model of theory-reduction and the way it is represented in the literature are shown to be incompatible with the careful remarks on the notion of reduction Nagel gave while developing his model. Based on these remarks, an alternative model is outlined which does not face some of the problems the official model faces. Taking the context in which Nagel developed his model into account, it is shown that the way Nagel shaped his model and, thus, its well-known deficiencies, (...) are best conceived of as a mere by-product of his philosophical background.

The goal of the book is to present the latest research on the new challenges of data technologies. It will offer an overview of the social, ethical and legal problems posed by group profiling, big data and predictive analysis and of the different approaches and methods that can be used to address them. In doing so, it will help the reader to gain a better grasp of the ethical and legal conundrums posed by group profiling. The volume first maps the (...) current and emerging uses of new data technologies and clarifies the promises and dangers of group profiling in real life situations. It then balances this with an analysis of how far the current legal paradigm grants group rights to privacy and data protection, and discusses possible routes to addressing these problems. Finally, an afterword gathers the conclusions reached by the different authors and discuss future perspectives on regulating new data technologies. (shrink)

Many industry leaders and academics from the field of machine ethics would have us believe that the inevitability of robots coming to have a larger role in our lives demands that robots be endowed with moral reasoning capabilities. Robots endowed in this way may be referred to as artificial moral agents. Reasons often given for developing AMAs are: the prevention of harm, the necessity for public trust, the prevention of immoral use, such machines are better moral reasoners than humans, and (...) building these machines would lead to a better understanding of human morality. Although some scholars have challenged the very initiative to develop AMAs, what is currently missing from the debate is a closer examination of the reasons offered by machine ethicists to justify the development of AMAs. This closer examination is especially needed because of the amount of funding currently being allocated to the development of AMAs coupled with the amount of attention researchers and industry leaders receive in the media for their efforts in this direction. The stakes in this debate are high because moral robots would make demands on society; answers to a host of pending questions about what counts as an AMA and whether they are morally responsible for their behavior or not. This paper shifts the burden of proof back to the machine ethicists demanding that they give good reasons to build AMAs. The paper argues that until this is done, the development of commercially available AMAs should not proceed further. (shrink)

We present a faithful axiomatization of von Mises' notion of a random sequence, using an abstract independence relation. A byproduct is a quantifier elimination theorem for Friedman's "almost all" quantifier in terms of this independence relation.

Suppose we have a stack of cards that is divided over some players. For certain distributions of cards it is possible to communicate your hand of cards to another player by public announcements, without yet another player learning any of your cards. A solution to this problem consists of some sequence of announcements and is called an exchange. It is called a direct exchange if it consists of (the minimum of) two announcements only. The announcements in an exchange have a (...) special form: they are safe communications, an interesting new form of update. Certain unsafe communications turn out to be unsuccessful updates. A communication is a public announcement that is known to be true. Each communication may be about a set of alternative card deals only, and even about a set of alternatives to the communicating player's own hand only. We list the direct exchanges for a deal of seven cards where the two players holding three cards communicate their hands to each other. Our work may be applicable to the design of cryptographic protocols. (shrink)

A scientific theory offers models for the phenomena in its domain; these models involve theoretical quantities, and a model's structure is the set of relations it imposes on these quantities. A fundamental demand in scientific practice is for those quantities to be clearly and feasibly related to measurement. This demand for empirical grounding can be articulated by displaying the theory-dependent criteria for a procedure to count as a measurement and for identifying the quantity it measures.

BackgroundVarious forms of Clinical Ethics Support (CES) have been developed in health care organizations. Over the past years, increasing attention has been paid to the question of how to foster the quality of ethics support. In the Netherlands, a CES quality assessment project based on a responsive evaluation design has been implemented. CES practitioners themselves reflected upon the quality of ethics support within each other’s health care organizations. This study presents a qualitative evaluation of this Responsive Quality Assessment (RQA) project.MethodsCES (...) practitioners’ experiences with and perspectives on the RQA project were collected by means of ten semi-structured interviews. Both the data collection and the qualitative data analysis followed a stepwise approach, including continuous peer review and careful documentation of the decisions.ResultsThe main findings illustrate the relevance of the RQA with regard to fostering the quality of CES by connecting to context specific issues, such as gaining support from upper management and to solidify CES services within health care organizations. Based on their participation in the RQA, CES practitioners perceived a number of changes regarding CES in Dutch health care organizations after the RQA: acknowledgement of the relevance of CES for the quality of care; CES practices being more formalized; inspiration for developing new CES-related activities and more self-reflection on existing CES practices.ConclusionsThe evaluation of the RQA shows that this method facilitates an open learning process by actively involving CES practitioners and their concrete practices. Lessons learned include that “servant leadership” and more intensive guidance of RQA participants may help to further enhance both the critical dimension and the learning process within RQA.

Precision livestock farming (PLF) is the management of livestock using the principles and technology of process engineering. Key to PLF is the dense monitoring of variegated parameters, including animal growth, output of produce (e.g. milk, eggs), diseases, animal behaviour, and the physical environment (e.g. thermal micro-environment, ammonia emissions). While its proponents consider PLF a win-win strategy that combines production efficiency with sustainability goals and animal welfare, critics emphasise, inter alia, the potential interruption of human-animal relationships. This paper discusses the notion (...) that the objectification of animals by PLF influences the developmental pathways of conventional industrial farming. We conduct a conceptual analysis of objectification by comparing discussions in feminist ethics and animal ethics. We find that in animal ethics, objectification includes deontological arguments regarding instrumentalisation, de-animalisation, alienation, commodification and quantification of animals. The focus on socio-political context and relationality connects these debates to central ideas in care ethics. We adopt a care ethics perspective to assess the implications of the objectification of animals in livestock farming. The basic claim is that sensory knowledge symbolised by the farmers’ unity of hand, head and heart would make it harder to objectify animals than abstract and instrumental reasoning where the pursuit of knowledge is intertwined with the pursuit of control, as in mainstream PLF. Despite of what can be considered as a good caring relationship between farmers and animals that is mediated by PLF, people involved in conventional industrial farming still seem to become further detached from farmers and animals, because the PLF system itself is objectifying. PLF redefines the notion of care, in terms of data transparency, standardisation of methods for analysis, real-time collection and processing of data, remote control, and the use of digital platforms. This creates new expectations and requires a redistribution of responsibilities within a wider scope of relations in the value chain. (shrink)

To tackle zoonotic disease threats, a One Health approach is currently commonplace and generally understood as an integrated effort of multiple disciplines to promote the health of humans, animals and the environment. To implement One Health strategies in zoonotic disease control, many countries set up early warning systems, in which human and veterinary health professionals cooperate. These systems, like the Dutch Zoonoses Structure, can be successful to detect emerging disease threats. However, these systems are not well equipped to handle moral (...) dilemmas that can arise in zoonotic disease control, like the culling of healthy animals. This research studies the role of normative presuppositions of professionals involved in zoonotic disease control policies in the Netherlands. We found that these professionals in general adhered to a holistic view of the One Health concept, however, in practice an anthropocentric approach was dominant. Public health was identified as the trumping moral value, which reveals an inherent field of tension with the core of One Health thinking. The lack of ethical expertise in control systems for zoonotic diseases can lead to misconception of ethical principles, like the precautionary principle which is frequently evoked to justify disease control measures.

Vaccination programmes against infectious diseases aim to protect individuals from serious illness but also offer collective protection once a sufficient number of people have been immunized. This so-called ‘herd immunity’ is important for individuals who, for health reasons, cannot be immunized or who respond less well to vaccines. For these individuals, it is pivotal that others establish group protection. However, herd immunity can be compromised when people deliberately decide not to be immunized and benefit from the herd’s protection. These agents (...) are often referred to as free riders: their omissions are deemed to be unfair to those who do contribute to the collective’s health. This article addresses the unfairness of such ‘free riding’. An argument by Garett Cullity is examined, which asserts that the unfairness of moral free riding lies neither in one’s intentions, nor in one’s reluctance to embrace a public good. This argument offers a strong basis for justifiably arguing that free riding is unfair. However, it is then argued that other considerations also need to be taken into account before simply holding free riding against non-compliers. (shrink)

In this entry, I seek to show the interdependence of questions about self-deception in philosophy of mind, psychology, and ethics. I taxonomize solutions to the paradoxes of self-deception, present possible psychological mechanisms behind it, and highlight how different approaches to the philosophy of mind and psychology will affect how we answer important ethical questions. Is self-deception conducive to happiness? How does self-deception affect responsibility? Is there something intrinsically wrong with self-deception? The entry, on the one hand, is a tour of (...) the literature; on the other, it is a case for more work that crosses traditional sub-disciplinary boundaries. (shrink)

In this article, we develop a bimodal perspective on possibility semantics, a framework allowing partiality of states that provides an alternative modelling for classical propositional and modal logics. In particular, we define a full and faithful translation of the basic modal logic K over possibility models into a bimodal logic of partial functions over partial orders, and we show how to modulate this analysis by varying across logics and model classes that have independent topological motivations. This relates the two realms (...) under comparison both semantically and syntactically at the level of derivations. Moreover, our analysis clarifies the interplay between the complexity of translations and axiomatizations of the corresponding logics: adding axioms to the target bimodal logic simplifies translations, or vice versa, complex translations can simplify frame conditions. We also investigate a transfer of first-order correspondence theory between possibility semantics and its bimodal counterpart. Finally, we discuss the conceptual trade-off between giving translations and giving new semantics for logical systems, and we identify a number of further research directions to which our analysis gives rise.

Recent years saw the rise of an interest in the roles and significance of thought experiments in different areas of human thinking. Heisenberg's gamma ray microscope is no doubt one of the most famous examples of a thought experiment in physics. Nevertheless, this particular thought experiment has not received much detailed attention in the philosophical literature on thought experiments up to date, maybe because of its often claimed inadequacies. In this paper, I try to do two things: to provide an (...) interesting interpretation of the roles played by Heisenberg's gamma ray microscope in interpreting quantum mechanics – partly based on Thomas Kuhn’s views on the function of thought experiments – and to contribute to the ongoing discussions on the roles and significance of thought experiments in physics.

While the design of sex robots is still in the early stages, the social implications of the potential proliferation of sex robots into our lives has been heavily debated by activists and scholars from various disciplines. What is missing in the current debate on sex robots and their potential impact on human social relations is a targeted look at the boundedness and bodily expressivity typically characteristic of humans, the role that these dimensions of human embodiment play in enabling reciprocal human (...) interactions, and the manner in which this contrasts with sex robot-human interactions. Through a fine-grained discussion of these themes, rooted in fruitful but largely untapped resources from the field of enactive embodied cognition, we explore the unique embodiment of sex robots. We argue that the embodiment of the sex robot is constituted by what we term restricted expressivity and a lack of bodily boundedness and that this is the locus of negative but also potentially positive implications. We discuss the possible benefits that these two dimensions of embodiment may have for people within a specific demographic, namely some persons on the autism spectrum. Our preliminary conclusion—that the benefits and the downsides of sex robots reside in the same capability of the robot, its restricted expressivity and lack of bodily boundedness as we call it—demands we take stock of future developments in the design of sex robot embodiment. Given the importance of evidence-based research pertaining to sex robots in particular, as reinforced by Nature for drawing correlations and making claims, the analysis is intended to set the stage for future research. -/- .

[OPEN ACCESS TARGET ARTICLE WITH COMMENTARIES AND RESPONSE] We develop a new model of how human agency-detection capacities and other socio-cognitive biases are involved in forming religious beliefs. Crucially, we distinguish general religious beliefs (such as *God exists*) from personal religious beliefs that directly refer to the agent holding the belief or to her peripersonal time and space (such as *God appeared to _me_ last night*). On our model, people acquire general religious beliefs mostly from their surrounding culture; however, people (...) use agency-intuitions and other low-level experiences to form personal religious beliefs. We call our model the Interactive Religious Experience Model (IREM). IREM inverts received versions of Hyperactive Agency-Detection Device Theory (HADD Theory): instead of saying that agency-intuitions are major causes of religious belief in general, IREM says that general belief in supernatural agents causes people to seek situations that trigger agency-intuitions and other experiences, since these enable one to form personal beliefs about those agents. In addition to developing this model, we (1) present empirical and conceptual difficulties with received versions of HADD Theory, (2) explain how IREM incorporates philosophical work on indexical belief, (3) relate IREM to existing anthropological and psychological research, and (4) propose future empirical research programs based on IREM.

Dynamic logic, broadly conceived, is the logic that analyses change by decomposing actions into their basic building blocks and by describing the results of performing actions in given states of the world. The actions studied by dynamic logic can be of various kinds: actions on the memory state of a computer, actions of a moving robot in a closed world, interactions between cognitive agents performing given communication protocols, actions that change the common ground between speaker and hearer in a conversation, (...) actions that change the contextually available referents in a conversation, and so on.

Guarded actions are changes with preconditions acting as a guard. Guarded action models are multimodal Kripke models with the valuations replaced by guarded actions.

This paper presents the outline of an ontology of the social realm that aims to provide a new perspective to the study of social phenomena. It will be argued that in order to raise the impact of the social sciences, research should start from a new ontological discursive perspective. This implies that rather than dividing the social and psychological realm into different “disciplines”, the social and the psychological realm need to be imagined as two sides of the same coin. And (...) also, that space and time should not be regarded as the primary referential grid for the social sciences but conversations and people. Within this perspective the “substance” of the social realm can be imagined as a species-wide and history-long web of conversations between people in which speech-acts are the basic forces that create agents and structures. The power of speech-acts is in essence non-local: it does not matter much where and when they occur, but rather by whom and in which conversational contexts they are uttered. This can be captured by the metaphor of social entanglement where social events have particular bonds that transcend space and time. All of this resonates more with the probabilistic realm of quantum physics than with the Newtonian world were causality reigns. (shrink)
