We deal with the ranking problem of the nodes in a directed graph. The bilateral relationships specified by a directed graph may reflect the outcomes of a sport competition, the mutual reference structure between websites, or a group preference structure over alternatives. We introduce a class of scoring methods for directed graphs, indexed by a single nonnegative parameter α. This parameter reflects the internal slackening of a node within an underlying iterative process. The class of so-called internal slackening scoring methods, (...) denoted by λα, consists of the limits of these processes. It is seen that λ0 extends the invariant scoring method, while λ∞ extends the fair bets scoring method. Method λ1 corresponds with the existing λ-scoring method of Borm et al. (Ann Oper Res 109(1):61–75, 2002) and can be seen as a compromise between λ0 and λ∞. In particular, an explicit proportionality relation between λα and λ1 is derived. Moreover, the internal slackening scoring methods are applied to the setting of social choice situations where they give rise to a class of social choice correspondences that refine both the Top cycle correspondence and the Uncovered set correspondence.

Vladimir Solov'ev (1853-1900- is regarded as the most original and systematic of the Russian philosophers in the 19th century. He has once again become the subject of international scholarly attention both in Slavic countries and the West. This volume contains selected papers presented at the international conference on Vladimir Solov'ev held at Nijmegen University, the Netherlands, in September 1998. The scope of this conference was wide-ranging, dealing with theological, metaphysical, philosophical and historical themes. Though Solov'ev's broad intellectual activity defies any (...) strict attempt at categorisation, the editors have classified its major themes under the dual characteristic of reconciliation and polemics. Solov'ev was passionately committed to the reconciliation of all beings under the idea of all-unity, which he attemted to achieve by engaging in uncompromising polemics with his contemporaries, The thirty contributors to this volume are specialists from Russia, Ukraine, Bulgaria, Western Europe and the United States. The volume makes a significant contribution to the intellectual reassesment of Vladimir Solov'ev since the rediscovery of his philosophical heritage in his own homeland in the 1980s. (shrink)

Digraph games are cooperative TU-games associated to domination structures which can be modeled by directed graphs. Examples come from sports competitions or from simple majority win digraphs corresponding to preference profiles in social choice theory. The Shapley value, core, marginal vectors and selectope vectors of digraph games are characterized in terms of so-called simple score vectors. A general characterization of the class of (almost positive) TU-games where each selectope vector is a marginal vector is provided in terms of game semi-circuits. (...) Finally, applications to the ranking of teams in sports competitions and of alternatives in social choice theory are discussed. (shrink)

A symmetric network consists of a set of positions and a set of bilateral links between these positions. For every symmetric network we define a cooperative transferable utility game that measures the “power” of each coalition of positions in the network. Applying the Shapley value to this game yields a network power measure, the β-measure, which reflects the power of the individual positions in the network. Applying this power distribution method iteratively yields a limit distribution, which turns out to be (...) proportional to the well-known degree measure. We compare the β-measure and degree measure by providing characterizations, which differ only in the normalization that is used. (shrink)

Aneuploidy, an aberrant number of chromosomes in a cell, is a feature of several syndromes associated with cognitive and developmental defects. In addition, aneuploidy is considered a hallmark of cancer cells and has been suggested to play a role in neurodegenerative disease. To better understand the relationship between aneuploidy and disease, various methods to measure the chromosome numbers in cells have been developed, each with their own advantages and limitations. While some methods rely on dividing cells and thus bias aneuploidy (...) rates to that population, other, more unbiased methods can only detect the average aneuploidy rates in a cell population, cloaking cell‐to‐cell heterogeneity. Furthermore, some techniques are more prone to technical artefacts, which can result in over‐ or underestimation of aneuploidy rates. In this review, we provide an overview of several “traditional” karyotyping methods as well as the latest high throughput next generation sequencing karyotyping protocols with their respective advantages and disadvantages.

The EDPS Ethics Advisory Group (EAG) has carried out its work against the backdrop of two significant social-political moments: a growing interest in ethical issues, both in the public and in the private spheres and the imminent entry into force of the General Data Protection Regulation (GDPR) in May 2018. For some, this may nourish a perception that the work of the EAG represents a challenge to data protection professionals, particularly to lawyers in the field, as well as to companies (...) struggling to adapt their processes and routines to the requirements of the GDPR. What is the purpose of a report on digital ethics, if the GDPR already provides all regulatory requirements to protect European citizens with regard to the processing of their personal data? Does the existence of this EAG mean that a new normative ethics of data protection will be expected to fill regulatory gaps in data protection law with more flexible, and thus less easily enforceable ethical rules? Does the work of the EAG signal a weakening of the foundation of legal doctrine, such as the rule of law, the theory of justice, or the fundamental values supporting human rights, and a strengthening of a more cultural approach to data protection? Not at all. The reflections of the EAG contained in this report are not intended as the continuation of policy by other means. It neither supersedes nor supplements the law or the work of legal practitioners. Its aims and means are different. On the one hand, the report seeks to map and analyse current and future paradigm shifts which are characterised by a general shift from analogue experience of human life to a digital one. On the other hand, and in light of this shift, it seeks to re-evaluate our understanding of the fundamental values most crucial to the well-being of people, those taken for granted in a data-driven society and those most at risk. The objective of this report is thus not to generate definitive answers, nor to articulate new norms for present and future digital societies but to identify and describe the most crucial questions for the urgent conversation to come. This requires a conversation between legislators and data protection experts, but also society at large - because the issues identified in this report concern us all, not only as citizens but also as individuals. They concern us in our daily lives, whether at home or at work and there isn’t a place we could travel to where they would cease to concern us as members of the human species. (shrink)

Background Scientific and technological advancements in mapping and understanding the interrelated pathways through which biological and environmental exposures affect disease development create new possibilities for detecting disease risk factors. Early detection of such risk factors may help prevent disease onset or moderate the disease course, thereby decreasing associated disease burden, morbidity, and mortality. However, the ethical implications of screening for disease risk factors are unclear and the current literature provides a fragmented and case-by-case picture. Methods To identify key ethical considerations (...) arising from the early detection of disease risk factors, we performed a systematic scoping review. The Scopus, Embase, and Philosopher’s Index databases were searched for peer-reviewed, academic records, which were included if they were written in English or Dutch and concerned the ethics of (1) early detection of (2) disease risk factors for (3) disease caused by environmental factors or gene-environment interactions. All records were reviewed independently by at least two researchers. Results After screening 2034 titles and abstracts, and 112 full papers, 55 articles were included in the thematic synthesis of the results. We identified eight common ethical themes: (1) Reliability and uncertainty in early detection, (2) autonomy, (3) privacy, (4) beneficence and non-maleficence, (5) downstream burdens on others, (6) responsibility, (7) justice, and (8) medicalization and conceptual disruption. We identified several gaps in the literature, including a relative scarcity of research on ethical considerations associated with environmental preventive health interventions, a dearth of practical suggestions on how to address expressed concerns about overestimating health capacities, and a lack of insights into preventing undue attribution of health responsibility to individuals. Conclusions The ethical concerns arising with the early detection of risk factors are often interrelated and complex. Comprehensive ethical analyses are needed that are better embedded in normative frameworks and also assess and weigh the expected benefits of early risk factor detection. Such research is necessary for developing and implementing responsible and fair preventive health policies. (shrink)

University students are at elevated risk for psychological distress, especially during the COVID-19 pandemic. The aim of this study was to warmly contact our students and investigate the psychological impact of the COVID-19 pandemic on the subjective wellbeing and levels of psychological symptoms of university students in Belgium. All bachelor and master students of the Vrije Universiteit Brussels were invited for a brief structured telephone interview in March, 2021. In total, 7,154 students were assessed by a structured interview, based on (...) the Kessler Psychological Distress Scale and the Anamnestic Comparative Self-Assessment. Compared to a representative sample, students considered their life during the pandemic as less satisfying compared to their life before the pandemic. Overall, all students have suffered from COVID-19 and the measures taken to contain the pandemic. Twenty percent of our sample of 7,154 VUB students scored above the K6 cutoff, indicating a heightened risk for having a diagnosable mental illness severe enough to cause functional limitations and to require treatment. This study highlights the need for psychological support for all students, during the COVID-19 pandemic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Herman Daly’s Economics for a Full World: His Life and Ideas by Peter VictorJeroen Van Den Bergh (bio)Victor, Peter (2022). Herman Daly’s Economics for a Full World: His Life and Ideas. Routledge, Oxon UK and New York USA (ISBN: 978–0–367-55694-5).Herman Daly (1938–2022) spent a lifetime thinking about how to achieve a sustainable economy. In an inclusive biography, Canadian economist and environmental scientist Peter Victor discusses (...) his ideas, critiques and debates with others, while clarifying his motivations and struggles. Daly has greatly influenced others, as reflected by numerous prizes awarded to him. This influence is confirmed by original text boxes in the book that contain statements of many colleagues about his work and person, obtained through a questionnaire survey by the author.As a young man, Daly decided to study economics as he imagined it combined humanities and science. He was disappointed in it being less scientific than hoped, but his environmental concern motivated him to work on reestablishing the foundations of the field in environmental science and ethics. Daly is best known for his critique of economic growth and his alternative of the “steady-state economy.” He contributed, however, many other novel concepts and ideas during his lifetime, such as the ends-means spectrum, empty vs full world, uneconomic growth and optimal scale.Victor explains these ideas in a calm pace, showing a deep knowledge of Daly’s work. He, moreover, is able to connect it to ongoing sustainability research. He does all this in the course of thirteen chapters, covering Daly’s early life, education and career, his views on economics, his personal philosophy and the role of religion, his proposal for a steady-state economy, and his opinions on economic growth, population and migration, money and banking, and the perils of trade. [End Page 117]Ultimate endsMany consider Herman Daly to be a heterodox and even heretic economist. He associates himself with ecological economics, the field he co-founded. But while some of his ideas seem radical, many of his core proposals do not deviate substantially from mainstream economics. For instance, his “ultimate ends” concept is perfectly consistent with the broad notion of “welfare” in standard economics. In line with this, many welfare economists—such as Samuelson (1961), Mishan (1967), Hirsch (1976), Sen (1976), Scitovsky (1976) and Frank (1985)—have expressed themselves as critical of GDP (gross domestic product) dominance and growthmania (van den Bergh 2009). In fact, neoclassical economics is not married to economic growth—this is more the empirical side of macroeconomics. While Daly recognizes these subtleties, some of his followers do not.Daly sees his Protestant religion as delivering the ultimate ends, but Victor notes that this has not led to concrete suggestions. Ultimate ends based in Christian religion may be motivated by the promise of eternal (after)life, which in effect means gratifying selfish preferences. Instead, a humanistic perspective—which Daly also seems to embrace—would stress solidarity with future generations and a bioethical view of solidarity with other species. These distinct viewpoints, combined with diversity of human preferences and experiences, suggest that it will be difficult if not impossible for democratic societies to agree upon ultimate means.The Index of Sustainable Economic Welfare (ISEW), a kind of greened or sustainable GDP metric, is Daly’s most concrete elaboration of ultimate means (Daly and Cobb 1989). For many OECD (Organization for Economic Cooperation and Development) countries, it indicates a stabilization of welfare, despite continued GDP growth (Lawn 2003; Posner and Costanza 2011). As clarified by Victor, The ISEW remains close to GDP, produces a monetary measure, has a simple and transparent calculation method, and received considerably attention from theoretical and empirical angles. In view of this, it may well represent the best candidate for a beyond-GDP metric that can replace the GDP. What urgently fails is an effective institutional procedure to achieve its widespread adoption (van den Bergh 2022).Religion, evolution and biodiversityDaly’s religious standpoint make him skeptical of the modern scientific worldview which regards the world to be governed by materialism and evolution, with no role for a higher purpose or an ultimate end. This led him... (shrink)

This paper zooms in on a recent development in the discussion between postphenomenology and critical constructivism: the attempt at working out a political philosophy in the framework of postphenomenology, specifically Peter-Paul Verbeek’s. Verbeek contrasts mediation theory to critical theory, arguing that critical theorists only “talk”; they don’t “do.” While the latter reproach postphenomenology/mediation theory for its lack of politics, Verbeek actually poses that “real” politics cannot be done by critical theorists—indeed exactly because of their not doing, that is, doing (...) in the sense of helping to design and develop good real-world technological solutions. But this brings up pertinent questions, about whether a theory should “do” something, what that means, and whether calls for “doing” do not carry their own presuppositions with them that, if not made explicit, will bias the theory and its “use” toward certain directions. These issues are explored by way of among others an excursion into Rortyan pragmatism. Eventually, I conclude, it is perfectly acceptable that critical constructivism should “talk” and postphenomenology “do”—as long as we keep the meanings of those terms sufficiently clear. (shrink)

In response to Peter–Paul Verbeek’s and Paul Levinson’s reviews of my article ‘In Between Us,’ I comment on four criticisms. Firstly, my approach of ‘mediation as such’ does not endorse the view of mediation as secondary to mediata (i.e., entities), but does not exclude it either. Secondly, my concepts of “transparency of use” and of “context” are to be seen as philosophical ‘tools’ and not as mutually exclusive states. Thirdly, I agree with Levinson that technologies do indeed remediate, and (...) mostly not for the worse. However, fourthly, at the same time we should always be on guard for their nefarious effects.

La parole est l'entre-deux qui sépare et unit moi et le monde, moi et toi, moi et moi-même. On se demande quelle est la relation entre moi et ma parole, si la parole découle de l'essence même de mon être. Une analyse phénoménologique, qui partirait du dialogue comme d'un donné indubitable, ne suffit pas tout à fait, puisqu'il il s'agit d'un sens éventuel du dialogue pour le tout de mon être. Il faut donc aborder la question d'un point de vue (...) d'où le dialogue lui-même est mis en suspens. Commençons par l'indubitable absolu : l'être. Il y a quelque chose, quoi que ce soit, il y a au moins la question même de l'être. Mais cette question qui se met elle-même en question, se sait être. Et qu'est cela sinon moi-même, pas encore opposé, il est vrai, à toi, à lui, à nous ? Pourtant je ne suis pas l'être ; il y a en moi une dualité entre essence et être, et une dualité entre être et penser. Je sais que je suis, je cherche encore qui je suis. Eh bien, je suis « ici et maintenant » , c. à. d. je suis dans un ordre spatio-temporel, par mon corps, qui est donc ce qui m'exprime à moi-même, ma parole. Mais mon corps est originellement en commerce avec les êtres du monde, et j'ai le sentiment de cette situation par la perception et le comportement. En révélant le sens des êtres du monde, en leur donnant des noms de mon point de vue, je me nomme moi-même. En revenant sur la voie parcourue jusqu'ici, l'article démontre que ce n'est pas seulement mon monde que je nomme. Le « moi » de la certitude absolue est un « nous » pas encore détaillé. Et à l'intérieur de ce « nous » jaillit, par ta foi en moi, l'opposition communicative entre moi et toi, que j'expérimente surtout dans la corrélation de la voix et de l'ouïe. La parole fonde la communauté, puisqu'en exprimant mon être elle s'adresse à vous, et manifeste ainsi mon être comme « être-avec » . L'être même est infini, et donc communicabilité pure, et donc parole. Mais notre parole humaine n'est que participation déficiente de la communication immédiate qui serait l'identité de l'être, le connaître et l'aimer. Elle reste moyen, et donc succédané de l'immédiat, et donc ambigue. Notre dialogue doit se transcender dans l'inexprimable, dans le silence. La parole essentielle, la parole de l'amour, est pour les hommes la parole la plus dangereuse et la plus incertaine. Elle ne se prouve que par la fidélité. Mais tout ce que nous disons et faisons est destiné à devenir l'incarnation de cette parole. (shrink)

Este artículo sostiene que Platón constituye un interlocutor fructífero para la Teoría crítica. Desde un diálogo con Axel Honneth, argumentaremos primero que la metodología de crítica social desarrollada en la República posee elementos constructivo-racionales y reconstructivo-hermenéuticos. Luego, enfatizaremos dos conceptos prefigurados en dicha obra que, mediante Hegel, yacen en el trasfondo de la Teoría crítica, a saber: holismo y patología social. Ello nos permitirá articular, como conclusión, una “dialéctica de la justicia” que, en el sentido de Adorno & Horkheimer, recorre (...) la obra de Honneth. (shrink)

In his article In Between Us, Yoni van den Eede expands existing theories of mediation into the realm of the social and the political, focusing on the notions of opacity and transparency. His approach is rich and promising, but two pitfalls should be avoided. First, his concept of ‘in-between’ runs the risk to conceptualize mediation as a process ‘between’ pre-given entities. On the basis of current work in postphenomenology and actor-network theory, though, mediation should rather be seen as the origin (...) of entities, not as an intermediary between them. Second, Van den Eede’s separate discussion of transparency and opacity in ‘use’ and in ‘context’ runs the risk to make invisible the complementarity of the two dimensions. While transparency of use embodies an experiential form of the distinction between transparency and opacity, transparency of context embodies a more cognitive dimension of the distinction. Only by linking the two it becomes possible to take responsibility for the impact that technological mediations can have. Users and designers need a ‘double vision’ to simultaneously see the transparency of both use and context. (shrink)

Professor Roeper adresses a large question, whether probabilistic semantics is a kind of semantics at all. Happily, he does this via an exploration of a specific issue on which he and Professor Leblanc have done important work. That is the issue of how the relationship of logical consequence can be characterized as a relation denned in terms of probability. Let us follow him in calling a relevant relationship of the latter sort the degree of implication, and follow Professor Roeper on (...) his quest for a satisfactory one. (shrink)

We propose a novel type of low distortion radial embedding which focuses on one specific entity and its closest neighbors. Our embedding preserves near-exact distances to the focus entity and aims to minimize distortion between the other entities. We present an interactive exploration tool SolarView which places the focus entity at the center of a "solar system" and embeds its neighbors guided by concentric circles. SolarView provides an implementation of our novel embedding and several state-of-the-art dimensionality reduction and embedding techniques, (...) which we adapted to our setting in various ways. We experimentally evaluated our embedding and compared it to these state-of-the-art techniques. The results show that our embedding competes with these techniques and achieves low distortion in practice. Our method performs particularly well when the visualization, and hence the embedding, adheres to the solar system design principle of our application. Nonetheless - as with all dimensionality reduction techniques - the distortion may be high. We leverage interaction techniques to give clear visual cues that allow users to accurately judge distortion. We illustrate the use of SolarView by exploring the high-dimensional metric space of bibliographic entity similarities. (shrink)

After many policy attempts to tackle the persistent rise in the costs of health care, physicians are increasingly seen as potentially effective resource stewards. Frameworks including the quadruple aim, value-based health care and choosing wisely underline the importance of positive engagement of the health care workforce in reinventing the system–paving the way to real affordability by defining the right care. Current programmes focus on educating future doctors to provide ‘high-value, cost-conscious care’ (HVCCC), which proponents believe is the future of sustainable (...) medical practice. Such programmes, which aim to extend population-level allocation concerns to interactions between an individual doctor and patient, have generated lively debates about the ethics of expanding doctors’ professional accountability. To empirically ground this discussion, we conducted a qualitative interview study to examine what happens when resource stewardship responsibilities are extended to the consulting room. Attempts to deliver HVCCC were found to involve inevitable trade-offs between benefits to the individual patient and (social) costs, medical uncertainty and efficiency, and between resource stewardship and trust. Physicians reconcile this by justifying good-value care in terms of what is in the best interest of individual patients–redefining the currency of value from monetary costs to a patient’s quality of life, and cost-conscious care as reflective medical practice. Micro-level resource stewardship thus becomes a matter of working reflexively and reducing wasteful forms of care, rather than of making difficult choices about resource allocation. (shrink)
