The ongoing COVID-19 pandemic and resulting health and economic crisis has caused major disruptions in the functioning of food systems and revived the discussion on what forms balanced, effective and responsible crisis management. As part of its thought leadership and its social responsibility in times of crisis, WUR is uniquely placed to contribute to the scientific knowledge base and data collection mechanisms required for early recognition and rapid response. In addition, WUR takes on the challenge to generate timely insights into (...) the possible scenarios for the prevention of a crisis and during and after emergencies to enable our clients and stakeholders to make informed decisions. Lastly, WUR can provide a better understanding of the mechanisms of spillover, and tangible and practical tools to help reduce the risk of spillover events from occurring, prevent pathogen spread, or mitigate the impacts of a future pandemic. In its research institutes and university, WUR brings together expertise in human, animal, plant and environmental health, the global agri-food system, economics, social sciences, food safety and security, ethics, and policy. Here, in the knowledge that COVID-19 will not be the last pandemic, we present WUR’s ambition and capabilities towards an integrated global multi-stakeholder approach to the prevention and management of potentially pandemic diseases, across the four phases of crisis management; prevention, preparedness, response, and recovery and learning.

Three philosophical perspectives on the relation between technology and society are distinguished and discussed: 1) technology as an autonomous force that determines society; 2) technology as a human construct that can be shaped by human values, and 3) a co-evolutionary perspective on technology and society where neither of them determines the other. The historical evolution of the three perspectives is discussed and it is argued that all three are still present in current debates about technological change and how it may (...) affect society. This is illustrated for the case of Artificial Intelligence (AI). It is argued that each of the three perspectives contributes to the debate of AI but that the third has the strongest potential to uncover blind spots in the current debate. (shrink)

How are we to appraise new technological developments that may bring revolutionary social changes? Currently this is often done by trying to predict or anticipate social consequences and to use these as a basis for moral and regulatory appraisal. Such an approach can, however, not deal with the uncertainties and unknowns that are inherent in social changes induced by technological development. An alternative approach is proposed that conceives of the introduction of new technologies into society as a social experiment. An (...) ethical framework for the acceptability of such experiments is developed based on the bioethical principles for experiments with human subjects: non-maleficence, beneficence, respect for autonomy, and justice. This provides a handle for the moral and regulatory assessment of new technologies and their impact on society. (shrink)

This article deals with the question of how self-organization in living organisms is realized. Self-organization may be observed in open systems that are out of equilibrium. Many disequilibria-conversion phenomena exist where free energy conversion occurs by spontaneously formed engines. However, how is self-organization realized in living entities? Living cells turn out to be self-organizing disequilibria-converting systems of a special kind. Disequilibrium conversion is realized in a typical way, through employing information specifying protein complexes acting as nano engines. The genetic code (...) enables processing of information—derived from coding DNA—to produce these molecular machines. Hence, information is at the core of living systems. Two promising approaches to explaining living cells containing sequences carrying information are mentioned. Also discussed is the question of whether a second concept of self-organization—namely, the Kantian concept—applies. (shrink)

This paper aims at contributing to a research agenda in engineering ethics by exploring the ethical aspects of engineering design processes. A number of ethically relevant topics with respect to design processes are identified. These topics could be a subject for further research in the field of engineering ethics. In addition, it is argued that the way design processes are now organised and should be organised from a normative point of view is an important topic for research.

We establish a completeness theorem for first-order basic predicate logic BQC, a proper subsystem of intuitionistic predicate logic IQC, using Kripke models with transitive underlying frames. We develop the notion of functional well-formed theory as the right notion of theory over BQC for which strong completeness theorems are possible. We also derive the undecidability of basic arithmetic, the basic logic equivalent of intuitionistic Heyting Arithmetic and classical Peano Arithmetic.

An arms race for an artificial general intelligence would be detrimental for and even pose an existential threat to humanity if it results in an unfriendly AGI. In this paper, an all-pay contest model is developed to derive implications for public policy to avoid such an outcome. It is established that, in a winner-takes-all race, where players must invest in R&D, only the most competitive teams will participate. Thus, given the difficulty of AGI, the number of competing teams is unlikely (...) ever to be very large. It is also established that the intention of teams competing in an AGI race, as well as the possibility of an intermediate outcome, is important. The possibility of an intermediate prize will raise the probability of finding the dominant AGI application and, hence, will make public control more urgent. It is recommended that the danger of an unfriendly AGI can be reduced by taxing AI and using public procurement. This would reduce the pay-off of contestants, raise the amount of R&D needed to compete, and coordinate and incentivize co-operation. This will help to alleviate the control and political problems in AI. Future research is needed to elaborate the design of systems of public procurement of AI innovation and for appropriately adjusting the legal frameworks underpinning high-tech innovation, in particular dealing with patenting by AI.

BackgroundResearch misconduct and questionable research practices have been the subject of increasing attention in the past few years. But despite the rich body of research available, few empirical works also include the perspectives of non-researcher stakeholders.MethodsWe conducted semi-structured interviews and focus groups with policy makers, funders, institution leaders, editors or publishers, research integrity office members, research integrity community members, laboratory technicians, researchers, research students, and former-researchers who changed career to inquire on the topics of success, integrity, and responsibilities in science. (...) We used the Flemish biomedical landscape as a baseline to be able to grasp the views of interacting and complementary actors in a system setting.ResultsGiven the breadth of our results, we divided our findings in a two-paper series with the current paper focusing on the problems that affect the integrity and research culture. We first found that different actors have different perspectives on the problems that affect the integrity and culture of research. Problems were either linked to personalities and attitudes, or to the climates in which researchers operate. Elements that were described as essential for success were often thought to accentuate the problems of research climates by disrupting research culture and research integrity. Even though all participants agreed that current research climates need to be addressed, participants generally did not feel responsible nor capable of initiating change. Instead, respondents revealed a circle of blame and mistrust between actor groups.ConclusionsOur findings resonate with recent debates, and extrapolate a few action points which might help advance the discussion. First, the research integrity debate must revisit and tackle the way in which researchers are assessed. Second, approaches to promote better science need to address the impact that research climates have on research integrity and research culture rather than to capitalize on individual researchers’ compliance. Finally, inter-actor dialogues and shared decision making must be given priority to ensure that the perspectives of the full research system are captured. Understanding the relations and interdependency between these perspectives is key to be able to address the problems of science.Study registrationhttps://osf.io/33v3m. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:More About Hume's Debt to Spinoza Wim Klever In a recent contribution to the question of Hume's relationship to SpinozaIadvocatedamoreorlessSpinozisticinterpretationofthefirst bookofA Treatise ofHumanNature.1 Ofthe Understanding, sowasmy claim, is not only very close to De natura et origine mentis (Ethica, second part) as far as its main affirmations are concerned; the convergence ofexternal and internal evidence makes it also probable that there is a remarkable influence from the one's work (...) on the other and, accordingly, that Hume's defamation of Spinoza's system might well have been disingenuous. This last point was previously also suggested by Richard Popkin in an article in which he compared Hume's philosophy ofreligion with Spinoza's.2 What motivated me to continue my research in this field? To say itinone word: the unintendeddiscoveryofmanystrikingresemblances betweenHume's secondbook, OfthePassions,andSpinoza'sthirdpart, De origine et natura affectuum. I happened to become a member of a group ofinterested people who concentrate on reading Hume, and, on the other hand, I had acquired some expertise as a Spinoza scholar for quite a number of years, so that I could not avoid seeing the commonaUties between the two philosophers. It seems to be fully impossible to explain the resemblances—which I, ofcourse, will show below—by referring to the Spinoza-article in Bayle's Dictionaire historique et critique (a source once mentioned by Hume in a letter to a London friend), since Bayle does not spend a word to the human passions. It is further a hard fact that there do not exist other written sourcesfrom which Humemighthave drawnhisSpinozisticinspiration in his French period apart from the Ethics; all available literature of the time turned around the questions theism versus atheism and free will versus determinism, without entering into the details ofhuman emotions.3 Only one conclusion was possible for me: Hume musthave been familiar with Spinoza's own text. Either the Chevaher Ramsay, whose intimate he was for some time,4 or anotherintermediaryfigure5 must have raised his interest. The best entrance into the material is constituted by Hume's closing remark in his A Dissertation on the Passions (1757), in which he elucidates what he in fact has been doing in hie analysis of the passions: Volume XDI Number 1 55 WIM KLEVER I pretend not to have here exhausted this subject. It is sufficient formy purpose, ifI have made it appear, that, in the production and conduct of the passions, there is a certain regular mechanism, which is susceptible of as accurate a disquisition, as the laws ofmotion, optics, hydrostatics, or any part ofnatural philosophy.6 In spite ofthe words "a certain," this fragment maynot be interpreted as a metaphorical assessment. The origin and the processes ofhuman passions are purely mechanical. If this is not what Hume intends to declare, he never could have added the phrase that passions are susceptible of exactly the same kind of accurate descriptions as other natural phenomena. This theory of the mechanism of the passions is certainly not Cartesian. Although Descartes, as a physical scientist, was a great promoter of the explanation of things by means of mechanical causality, he in fact did not extend this method to the life ofthe passions. In his dualistic philosophy he ascribes to the human mind (with its free will) the capability to interfere with the passions and even to dominate them.7 In this field it is Spinoza who paves the way for Hume by sharply criticizing Descartes' non-mechanistic explanation ofthe passions. His far-fetched solution ofthe mind-body interactivity by means of the pineal gland and the animal spirits pushing against it, is called "a hypothesis more occult than any occult quality." 8 Spinoza acknowledged that Descartes had good intentions in trying to explain the human affections by their direct causes, but he was inconsistent insofar as he at the same time attempted to demonstrate man's absolute dominion over them. He, Spinoza, on the contrary, "will consider human actions and appetites just as ifit were a question ofUnes, planes and bodies." 9 The analysis of passions is a piece of natural science comparable with geometry, optics10 and hydrostatics, to mention some other fields of Spinoza's research. Hume's statement... (shrink)

We characterize the first-order formulas with one free variable that are preserved under bisimulation and persistence or strong persistence over the class of Kripke models with transitive frames and unary persistent predicates.

In this article some of the presuppositions that underly the current ideas about decision making capacity, autonomy and independence are critically examined. The focus is on chronic disorders, especially on chronic physical disorders. First, it is argued that the concepts of decision making competence and autonomy, as they are usually applied to the problem of legal (in)competence in the mentally ill, need to be modified and adapted to the situation of the chronically (physically) ill. Second, it is argued that autonomy (...) and dependence must not be considered as two mutually exclusive categories. It is suggested that decision making may take on the form of a more or less conscious decision not to be involved in making all kinds of explicit and deliberate decisions. Elaborating on Agich's distinction between ideal and actual autonomy, the concept of Socratic autonomy is introduced. (shrink)

Six of today's greatest thinkers take on a plethora of issues and unanswered questions of late twentieth-century science, such as the boundaries of scientific inquiry, the possibility of conducting studies of creativity, and other topics.

Budgetary austerity has been implemented by all levels of government in Belgium since 1982. The public attention has focussed on the achievements of the centra[ level. However, also at the local level a remarkable budgetary retrenchment has been realised. This study investigates the various aspects of decremental budgeting of the Belgian municipolities, both at the expenditures and the revenues side.

This paper describes a teaching methodology whereby students can gain practical experience of ethical decision-making in the engineering design process. We first argue for the necessity to teach a ‘practical’ understanding of ethical issues in engineering education along with the usual theoretical or hypothetical approaches. We then show how this practical understanding can be achieved by using a collaborative design game, describing how, for example, the concept of responsibility can be explored from this practical basis. We conclude that the use (...) of games in design education can provide an excellent basis for discussing practical and ethical reasoning during the process of design. (shrink)

Should we conceive of corporations as entities to which moral responsibility can be attributed? This contribution presents what we will call a political account of corporate moral responsibility. We argue that in modern, liberal democratic societies, there is an underlying political need to attribute greater levels of moral responsibility to corporations. Corporate moral responsibility is essential to the maintenance of social coordination that both advances social welfare and protects citizens' moral entitlements. This political account posits a special capacity of self-governance (...) that corporations can intelligibly be said to possess. Corporations can be said to be "administrators of duty" in that they can voluntarily incorporate moral principles into their decision-making processes about how to conduct business. This account supplements and partly transforms earlier pragmatic accounts of corporate moral responsibility by disentangling responsibility from its conventional linkages with accountability, blame and punishment. It thereby represents a distinctive way to defend corporate moral responsibility and shows how Kantian thinking can be helpful in disentangling the problems surrounding the concept. (shrink)

This paper provides an early evaluation of Artificial Intelligence against COVID-19. The main areas where AI can contribute to the fight against COVID-19 are discussed. It is concluded that AI has not yet been impactful against COVID-19. Its use is hampered by a lack of data, and by too much data. Overcoming these constraints will require a careful balance between data privacy and public health, and rigorous human-AI interaction. It is unlikely that these will be addressed in time to be (...) of much help during the present pandemic. In the meantime, extensive gathering of diagnostic data on who is infectious will be essential to save lives, train AI, and limit economic damages. (shrink)

The ongoing energy transition toward more sustainable energy systems implies a change in the values for which such systems are designed. The energy transition however is not just about sustainability but also about values like energy security and affordability, and we witness the emergence of new values like energy justice and energy democracy. How can we understand such value changes and how can or should they affect the design of future energy systems? This introduction to the special section on value (...) change in energy systems introduces the main themes and questions. It discusses different understandings of values and value change, explains why the topic is important and how it can be methodologically studied. (shrink)

This volume contributes to the debate on the distinction between public and private spheres with regard to the role of religion in modern societies. This issue which is inherent to many conceptions regarding social order, modernity, freedom of conscience, and the changing role and function of religion is discussed not only from a social scientific but also from a historical and philosophical point of view.

This paper presents new results from a detailed study of the structure of autocatalytic sets. We show how autocatalytic sets can be decomposed into smaller autocatalytic subsets, and how these subsets can be identified and classified. We then argue how this has important consequences for the evolvability, enablement, and emergence of autocatalytic sets. We end with some speculation on how all this might lead to a generalized theory of autocatalytic sets, which could possibly be applied to entire ecologies or even (...) economies. (shrink)

Influential work on reasoning and decision-making has popularised the idea that sound reasoning requires correction of fast, intuitive thought processes by slower and more demanding deliberation. We present seven studies that question this corrective view of human thinking. We focused on the very problem that has been widely featured as the paradigmatic illustration of the corrective view, the well-known bat-and-ball problem. A two-response paradigm in which people were required to give an initial response under time pressure and cognitive load allowed (...) us to identify the presumed intuitive response that preceded the final response given after deliberation. Across our studies, we observe that correct final responses are often non-corrective in nature. Many reasoners who manage to answer the bat-and-ball problem correctly after deliberation already solved it correctly when they reasoned under conditions that minimised deliberation in the initial response phase. This suggests that sound bat-and-ball reasoners do not necessarily need to deliberate to correct their intuitions; their intuitions are often already correct. Pace the corrective view, findings suggest that in these cases, they deliberate to verify correct intuitive insights. (shrink)

Safe-by-design aims at addressing safety issues already during the R&D and design phases of new technologies. SbD has increasingly become popular in the last few years for addressing the risks of emerging technologies like nanotechnology and synthetic biology. We ask to what extent SbD approaches can deal with uncertainty, in particular with indeterminacy, i.e., the fact that the actual safety of a technology depends on the behavior of actors in the value chain like users and operators. We argue that while (...) indeterminacy may be approached by designing out users as much as possible in attaining safety, this is often not a good strategy. It will not only make it more difficult to deal with unexpected risks; it also misses out on the resources that users can bring for achieving safety, and it is undemocratic. We argue that rather than directly designing for safety, it is better to design for the responsibility for safety, i.e., designers should think where the responsibility for safety is best situated and design technologies accordingly. We propose some heuristics that can be used in deciding how to share and distribute responsibility for safety through design. (shrink)

Legal information retrieval is in need of the provision of legal knowledge for the improvement of search strategies. For this purpose, the LOIS project is concerned with the construction of a multilingual WordNet for cross-lingual information retrieval in the legal domain. In this article, we set out how a hybrid approach, featuring lexically and legally grounded conceptual representations, can fit the cross-lingual information retrieval needs of both legal professionals and laymen.

The participation of minors in clinical trials is essential to provide safe and effective medical care to children. Because few drugs have been tested in children, pediatricians are forced to prescribe medications off-label with uncertain efficacy and safety. In this article, we analyze how the enrollment of minors in clinical trials is negotiated within relationships of mutual trust between clinicians, minors, and their parents. After a brief description of the problems associated with involving minors in clinical research, we consider how (...) existing “relationships of trust” can be used as a place where the concerns of research subjects can be more fully discussed and addressed. Building on the tacit recognition of trust found in The European Clinical Trials Directive we make policy recommendations that allow for clearer, more ethically informed guidelines for enrolling minors in clinical research.

In classical propositional calculus for each proposition A(p) the following holds: $\vdash A(p) \leftrightarrow A^3(p)$ . In this paper we consider what remains of this in the intuitionistic case. It turns out that for each proposition A(p) the following holds: there is an n ∈ N such that $\vdash A^n(p) \leftrightarrow A^{n + 2}(p)$ . As a byproduct of the proof we give some theorems which may be useful elsewhere in propositional calculus.

El artículo trata de las huellas que el agustinismo del siglo XVI dejó en la exégesis bíblica de la facultad de teología de Lovaina. Como un ejemplo de esto, se abordan las obras de Cornelio Jansenio de Gante, subrayando su doble propósito académico y pastoral-litúrgico. Se estudian también las obras de Thomas Stapleton, Promptuaria y Antidota, señalando su intención de contrarrestar las interpretaciones bíblicas de Calvino, Beza y otros reformadores.

Through a careful analysis of the ethics of Philodemus, this monograph offers the first book-length study of the Epicurean sage. It explores the different aspects of the sage’s way of life and offers a reconstruction of this Epicurean role model.

Silent gestures consist of complex multi‐articulatory movements but are now primarily studied through categorical coding of the referential gesture content. The relation of categorical linguistic content with continuous kinematics is therefore poorly understood. Here, we reanalyzed the video data from a gestural evolution experiment (Motamedi, Schouwstra, Smith, Culbertson, & Kirby, 2019), which showed increases in the systematicity of gesture content over time. We applied computer vision techniques to quantify the kinematics of the original data. Our kinematic analyses demonstrated that gestures (...) become more efficient and less complex in their kinematics over generations of learners. We further detect the systematicity of gesture form on the level of thegesture kinematic interrelations, which directly scales with the systematicity obtained on semantic coding of the gestures. Thus, from continuous kinematics alone, we can tap into linguistic aspects that were previously only approachable through categorical coding of meaning. Finally, going beyond issues of systematicity, we show how unique gesture kinematic dialects emerged over generations as isolated chains of participants gradually diverged over iterations from other chains. We, thereby, conclude that gestures can come to embody the linguistic system at the level of interrelationships between communicative tokens, which should calibrate our theories about form and linguistic content.

Medicine does not usually consider the human body from an aesthetic point of view. This article explores the notion of the lived body as aesthetic object in anthropological medicine, concentrating on the views of Buytendijk and Straus on human uprightness and gracefulness. It is argued that their insights constitute a counter-balance to the way the human body is predominantly approached in medicine and medical ethics. In particular, (1) the relationship between anthropological, aesthetic and ethical norms, (2) the possible danger of (...) a naturalistic fallacy, (3) the implications for the care of disabled people and (4) the intrinsic aesthetic quality of the human body are dealt with.

In lieu of an abstract, here is a brief excerpt of the content:A Vindication Wim Klever Comparing Hume with Spinoza I am accused ofhaving misread both, at least in certain respects; I would have gone too far in considering Spinoza as an influential root of Hume's thought. On occasion of Dr. Leavitt's criticism I would like to stress the following points: 1. In spite ofWolfson'sendeavourtoreduceSpinozatoAristotelian, scholastic and Jewish sources ofthe Middle Ages, many texts—in fact all texts in which Aristotle ismentioned—constitute (...) aconvincingproof that Spinoza not only rejected,just like Hume, all sorts ofAristotelian and scholastic speculation, buteven showedmuch contemptfor them.1 In the same way there cannot be any doubt that he rejected Maimonides' Jewish Aristotelianism.2 In the TTP he defines his position in sharp contrast to Maimonides. 2.Nominalism means that names may be used for the indication of many items whereas ideas are essentially ideas of particulars. According to Spinoza everything is reflected in its own specific idea,3 whereas names like 'ens', 'aliquid', 'man', etc. may be the sign, sometimes ambiguously but often also without confusion, of more things, which are vaguely conceived. This confused idea, then, is nevertheless the properideaofaparticularblurredimageinthebrains. Some eminent scholars like Stuart Hampshire and Martial Gueroult (I confess: not all ofthem) pretend that Spinoza is a true nominalist. I think the texts (and the whole structure of the system) enforce us to confess that they are right. 3.In the case of common things, that is, (elementary) things common to all beings, the human body included, the ideas of these things are, though particular, common too.4 In spite ofand in line with Hume's agreement with Spinoza's nominalism he does not deny, as Leavitt pretends, the existence of common notions. In "Of the Passions," part 1, section 10, he writes that "according to common notions a man has no power, where very considerable motives Ue betwixt him and the satisfaction of his desires, and determine him to forbearwhathe wishes toperform."5Thispassageis notatallinconflict with Treatise 1.1.7 in which the real existence ofabstract ideas in our mind is refuted. The ideas of things we have in common with other natural beings, may not be called abstract for that reason. This section (T 17-25) is perfectly congruous with Spinoza's position. 4.I keep to my claim that there is a striking parallel between Spinoza's famous distinction between three kinds of knowledge Volume XVII Number 2 209 WIM KLEVER (2 Ethics 40s2) and some statements ofHume. Additional evidence for this claim (compared with what I gave already) is to find in Treatise 1.3.11, where Hume marks "several degrees of evidence,... distinguishing] human reason into three kinds, viz. that from knowledge, from proofs, and from probabilities" (T 124, first emphasis added); and in the Enquiry, where all objects of human reason are dividedinto three (!)kinds as well, namely"Relations ofIdeas... either intuitively or demonstratively certain" and "Matters ofFact."6 Put into a diagram the resemblance becomes even more apparent: Spinoza Ethics opinio/imaginatio ratio intuitio Hume TreatiseEnquiry probabilityMatters of Fact proofdemonstratively knowledgeintuitively Careful comparison ofthe texts shows that the functions attributed to the various kinds ofknowledge are exactly the same in Spinoza as in Hume, contrary to what is suggested by Leavitt. I only need to remind him ofthe 'Spinozistic' opening ofTreatise 1.3.3: "Tis a general maxim in philosophy, that whatever begins to exist, must have a cause of existence... Tis suppos'd to be founded on intuition,... All certainty arises from the comparison of ideas, and from the discovery of such relations as are unalterable" (T 78-79). Both philosophers locate the highest kind of knowledge in the evidence of mathematics and the common properties of nature, explained in physics. Let us not forget that both are fully naturalists, for whom the understanding of things "sub specie aeternitatis" (Spinoza's description of the third kind of knowledge) means in fact the intuition of the particular essence of things in a scientific way. 5.In the TractatusTheologico-Politicus itiscertainly not Spinoza's intention to show that the third kind of knowledge is identical with prophecy. On the contrary, in the first two chapters he clearly demonstrates, in his scientific hermeneutics, that prophecy is... (shrink)

A lot of research has been done on the detection of mental workload using various bio-signals. Recently, deep learning has allowed for novel methods and results. A plethora of measurement modalities have proven to be valuable in this task, yet studies currently often only use a single modality to classify MWL. The goal of this research was to classify perceived mental workload using a deep neural network that flexibly makes use of multiple modalities, in order to allow for feature sharing (...) between modalities. To achieve this goal, an experiment was conducted in which MWL was simulated with the help of verbal logic puzzles. The puzzles came in five levels of difficulty and were presented in a random order. Participants had 1 h to solve as many puzzles as they could. Between puzzles, they gave a difficulty rating between 1 and 7, seven being the highest difficulty. Galvanic skin response, photoplethysmograms, functional near-infrared spectrograms and eye movements were collected simultaneously using LabStreamingLayer. Marker information from the puzzles was also streamed on LSL. We designed and evaluated a novel intermediate fusion multimodal DNN for the classification of PMWL using the aforementioned four modalities. Two main criteria that guided the design and implementation of our DNN are modularity and generalisability. We were able to classify PMWL within-level accurate on a seven-level workload scale using the aforementioned modalities. The model architecture allows for easy addition and removal of modalities without major structural implications because of the modular nature of the design. Furthermore, we showed that our neural network performed better when using multiple modalities, as opposed to a single modality. The dataset and code used in this paper are openly available.
