Protein aggregation has been studied for at least 3 decades, and many of the principles that regulate this event are relatively well understood. Here, however, we present a different perspective to explain why proteins aggregate: we argue that aggregation may occur as a side‐effect of the lack of one or more natural partners that, under physiologic conditions, would act as chaperones. This would explain why the same surfaces that have evolved for functional purposes are also those that favour aggregation. In (...) the course of reviewing this field, we substantiate our hypothesis with three paradigmatic examples that argue for the generality of our proposal. An obvious corollary of this hypothesis is, of course, that targeting the physiological partners of a protein could be the most direct and specific approach to designing anti‐aggregation molecules. Our analysis may thus inform a different strategy for combating diseases of protein aggregation and misfolding. (shrink)

Protein misfolding is a topic that is of primary interest both in biology and medicine because of its impact on fundamental processes and disease. In this review, we revisit the concept of protein misfolding and discuss how the field has evolved from the study of globular folded proteins to focusing mainly on intrinsically unstructured and often disordered regions. We argue that this shift of paradigm reflects the more recent realisation that misfolding may not only be an adverse event, as originally (...) considered, but also may fulfil a basic biological need to compartmentalise the cell with transient reversible granules. We nevertheless provide examples in which structure is an important component of a much more complex aggregation behaviour that involves both structured and unstructured regions of a protein. We thus suggest that a more comprehensive evaluation of the mechanisms that lead to aggregation might be necessary. (shrink)

A student's future as a knowledge worker (one who "thinks for a living" with the task of problem solving) is the starting point of this book. With this in mind, the book combines a review of philosophical positions and problems with practical examples and perspectives gained from everyday challenges faced by knowledge workers in their businesses and organizations. Through the use of summative chapters, highlighted key concepts, questions for reflection, and illustrative examples on how to work with the theories presented, (...) the book provides a clear and accessible introduction to this challenging subject. Philosophy of Science primarily addresses students studying language, communication, marketing, economics, and management. However, the survey of the theoretical schools of thought - as well as the discussions on research ethics and the role of research in society - will be equally relevant for other students in the humanities and the natural and social sciences.

ABSTRACTThis article examines the Trinitarian anthropology inherent in the ‘charism of unity’ that characterizes the Focolare Movement stemming from the mystical experience of Chiara Lubich. After describing the theological cornerstones of this charism―namely the evangelical centrality of the commandment of reciprocal love, the circularity between theology and anthropology and Jesus Forsaken as the Christological key to understanding and achieving unity―the article studies its cultural implications as reflected in the philosophical and theological contribution of Klaus Hemmerle. In dialogue with modern thought, (...) Hemmerle in fact draws from and develops the anthropological meaning of the charism of unity as a feasible way to respond to the most acute challenges of today.

Traditionally, the manufacturer/operator of a machine is held (morally and legally) responsible for the consequences of its operation. Autonomous, learning machines, based on neural networks, genetic algorithms and agent architectures, create a new situation, where the manufacturer/operator of the machine is in principle not capable of predicting the future machine behaviour any more, and thus cannot be held morally responsible or liable for it. The society must decide between not using this kind of machine any more (which is not a (...) realistic option), or facing a responsibility gap, which cannot be bridged by traditional concepts of responsibility ascription.

Neural devices have the capacity to enable users to regain abilities lost due to disease or injury – for instance, a deep brain stimulator (DBS) that allows a person with Parkinson’s disease to regain the ability to fluently perform movements or a Brain Computer Interface (BCI) that enables a person with spinal cord injury to control a robotic arm. While users recognize and appreciate the technologies’ capacity to maintain or restore their capabilities, the neuroethics literature is replete with examples of (...) concerns expressed about agentive capacities: A perceived lack of control over the movement of a robotic arm might result in an altered sense of feeling responsible for that movement. Clinicians or researchers being able to record and access detailed information of a person’s brain might raise privacy concerns. A disconnect between previous, current, and future understandings of the self might result in a sense of alienation. The ability to receive and interpret sensory feedback might change whether someone trusts the implanted device or themselves. Inquiries into the nature of these concerns and how to mitigate them has produced scholarship that often emphasizes one issue – responsibility, privacy, authenticity, or trust – selectively. However, we believe that examining these ethical dimensions separately fails to capture a key aspect of the experience of living with a neural device. In exploring their interrelations, we argue that their mutual significance for neuroethical research can be adequately captured if they are described under a unified heading of agency. On these grounds, we propose an “Agency Map” which brings together the diverse neuroethical dimensions and their interrelations into a comprehensive framework. With this, we offer a theoretically-grounded approach to understanding how these various dimensions are interwoven in an individual’s experience of agency. (shrink)

As is well known, any preorder R on a set U induces an Alexandrov topology on U. In some interesting cases related to data mining an Alexandrov topology can be transformed into different types of logico-algebraic models. In some cases, (pre)topological operators provided by Pointless Topology may define a topological space on U even if R is not a preorder. If this is the case, then we call R a crypto-preorder. The paper studies the conditions under which a relation R (...) is a crypto-preorder and how to transform a crypto-preorder into a proper preorder. (shrink)

These proceedings collect the selected contributions of participants of the First Karl Schwarzschild Meeting on Gravitational Physics, held in Frankfurt, Germany to celebrate the 140th anniversary of Schwarzschild's birth. They are grouped into 4 main themes: I. The Life and Work of Karl Schwarzschild; II. Black Holes in Classical General Relativity, Numerical Relativity, Astrophysics, Cosmology, and Alternative Theories of Gravity; III. Black Holes in Quantum Gravity and String Theory; IV. Other Topics in Contemporary Gravitation. Inspired by the foundational principle ``By (...) acknowledging the past, we open a route to the future", the week-long meeting, envisioned as a forum for exchange between scientists from all locations and levels of education, drew participants from 15 countries across 4 continents. In addition to plenary talks from leading researchers, a special focus on young talent was provided, a feature underlined by the Springer Prize for the best student and junior presentations.

Wittgenstein’s and Heidegger’s objections against the possibility of a science of aesthetics were influential on different sides of the analytic/continental divide. Heidegger’s anti-scientism leads him to an alētheic view of artworks which precedes and exceeds any possible aesthetic reduction. Wittgenstein also rejects the relevance of causal explanations, psychological or physiological, to aesthetic questions. The main aim of this paper is to compare Heidegger with Wittgenstein, showing that: there are significant parallels to be drawn between Wittgenstein’s and Heidegger’s anti-scientism about aesthetics, (...) and that their anti-scientism leads both towards partly divergent criticisms of what I will call ‘aestheticism’. The divergence is mainly due to a broader metaphilosophical disagreement concerning appeals to ordinary language. Thus situating the two philosophers’ positions facilitates a possible critical dialogue between analytic and continental approaches in aesthetics. (shrink)

Anche se siamo comunemente abituati a pensare alla scienza come a un qualcosa di assolutamente atemporale e indipendente da tutto, in realtà essa è profondamente influenzata dalla cultura e dalla società del tempo in cui vive. Infatti né la scienza è isolabile dalla società, né la società è isolabile dalla scienza, tanto meno come si sta configurando oggi. Per approfondire questi aspetti, esistono però due visioni antagoniste che bisogna superare: secondo la visione scolastica, retaggio del positivismo ottocentesco ancora molto diffuso (...) fra scienziati e pubblico di non esperti, la scienza è conoscenza senza soggetto conoscente. All'opposto, la visione cinica della scienza, sull'onda di talune elaborazioni della sociologia della scienza, la riduce a nient'altro che a una costruzione di soggetti che partecipano al gioco scientifico, una cultura come altre e da "mediare", e comunque una conoscenza relativa, se non frutto di una costruzione puramente soggettiva, arbitraria, ideologica. Un'analisi della costituzione sociale della scienza può, invece, mirare a un'indagine scientifica sulla scienza proprio configurando una relatività della conoscenza che supera sia l'assolutismo idealistico sia il relativismo soggettivistico.

Jason Brennan has argued that democracy is intrinsically unjust, for it grants voting power to politically incompetent individuals, thus exposing people to an undue risk of harm. He claims democracy should be replaced by epistocracy, i.e., the rule of the knowers. In this paper, I show that his argument fails. First, Brennan mistakes voters’ competence for voters’ trustworthiness. Second, despite Brennan's claim to the contrary, an epistocracy may not reduce people’s exposure to an undue risk of harm. Third, Brennan overlooks (...) the fact that citizens are not equally affected by ‘bad voting.’ Fourth, far from being a defence of libertarian ideals, Brennan's argument supports paternalism.

Many believe that a citizen who engages in civil disobedience is not exempt from the sanctions that apply to standard law-breaking conduct. Since he is responsible for a deliberate breach of the law, he is also liable to punishment. Focusing on a conception of responsibility as answerability, I argue that a civil disobedient is responsible (i.e. answerable) to his fellows for the charges of wrongdoing, yet he is not liable to punishment merely for breaching the law. To support this claim, (...) I defend an account of political obligation framed in terms of respect for (rather than mere obedience to) the law, and argue that the mere illegality of civil disobedience does not suffice to establish wrongdoing. I then discuss and reject three objections to my argument. (shrink)

Alzheimer's disease remains the most common form of dementia. Dementia symptoms vary depending on individual personality, life experience, and social and cultural influences. As dementia progresses, involvement of multi-disciplinary health care professionals is needed to manage the disease. Alzheimer research is progressing rapidly. While 5% of all Alzheimer's disease may be genetically determined, the majority is not. Susceptibility genes can reveal the risk of contracting Alzheimer's disease. Early life risk factors such as education, nutrition, and vascular disease may increase the (...) likelihood of dementia in later life. In the United States, two acetylcholinesterase inhibitors have been approved as cognitive enhancers. Possible prevention and symptomatic treatment interventions have focused on estrogen replacement therapy, antioxidants, and anti-inflammatory medications. Research advances have improved the clinical management of dementia. Ethical implications to the patient, family, and society are multiple and remain challenging. (shrink)

The fair-play theory of punishment claims that the state is justified in imposing additional burdens on law-breakers, to remove the unfair advantage the latter have enjoyed by disobeying the law. From this perspective, punishment reestablishes a fair distribution of benefits and burdens among all citizens. In this paper, I object to this view by focusing on the case of civil disobedience. I argue that the mere illegality of this conduct is insufficient to establish the agent’s unfair advantage over his lawabiding (...) fellows, hence the imposition of additional burdens upon him through legal punishment. I articulate a broader account of citizens’ fair-play duties, able to capture disobedience as well as obedience to the law. While claiming that some law-breakers may not be treated as free-riders, I also gesture at the fact that some law-obeying citizens may not be ‘playing fair’: in some cases, a failure to engage in civil disobedience represents a failure to do one’s own part within the cooperative scheme of society.
