Unilateral spatial neglect is a disorder characterized by the failure to report, respond to, or orient toward the contralateral side of space to a brain lesion. Current assessment methods often fail to discover milder forms, cannot differentiate between unilateral spatial neglect subtypes and lack ecological validity. There is also a need for treatment methods that target subtypes. Immersive virtual reality systems in combination with eye-tracking have the potential to overcome these shortcomings, by providing more naturalistic environments and tasks, with sensitive (...) and detailed measures. This systematic review examines the state of the art of research on these technologies as applied in the assessment and treatment of USN. As we found no studies that combined immersive VR and ET, we reviewed these approaches individually. The review of VR included seven articles, the ET review twelve. The reviews revealed promising results. All included studies found significant group-level differences for several USN measures. In addition, several studies found asymmetric behavior in VR and ET tasks for patients who did not show signs of USN in conventional tests. Particularly promising features were multitasking in complex VR environments and detailed eye-movement analysis. No VR and only a few ET studies attempted to differentiate USN subtypes, although the technologies appeared appropriate. One ET study grouped USN participants using individual heatmaps, and another differentiated between subtypes on drawing tasks. Regarding ecological validity, although no studies tested the prognostic validity of their assessment methods, VR and ET studies utilized naturalistic tasks and stimuli reflecting everyday situations. Technological characteristics, such as the field of view and refresh rate of the head-mounted displays, could be improved, though, to improve ecological validity. We found no studies that utilized VR or ET technologies for USN treatment up until the search date of the 26th of February 2020. In conclusion, VR-ET-based systems show great potential for USN assessment. VR-ET holds great promise for treatment, for example, by monitoring behavior and adapting and tailoring to the individual person’s needs and abilities. Future research should consider developing methods for individual subtypes and differential diagnostics to inform individual treatment programs. (shrink)

Although Darwinian concepts have largely been banned from the social sciences of the last century, they have recently seen a revival in several disciplines such as sociology, anthropology, or economics. Most of the current proponents of evolutionary theorizing in the social sciences avoid references to the older literature on social evolution. On that background, this article presents a contribution to Darwinist thinking in early American sociology that has mainly been overlooked in the literature. As the leading figure of the Human (...) Ecology Approach, which was established during the 1920s and 1930s, Robert Ezra Park drew heavily on evolutionary concepts to explain human evolution. A systematic presentation of these concepts in the light of the modern discussion on sociocultural evolution is given, followed by a conclusion about what can be learned from Park today. (shrink)

The revised edition contains a new chapter which provides an elegant description of the semantics. The various classes of lambda calculus models are described in a uniform manner. Some didactical improvements have been made to this edition. An example of a simple model is given and then the general theory (of categorical models) is developed. Indications are given of those parts of the book which can be used to form a coherent course.

Hendrik Lorenz presents a comprehensive study of Plato's and Aristotle's conceptions of non-rational desire. They see this as something that humans share with animals, and which aims primarily at the pleasures of food, drink, and sex. Lorenz explores the cognitive resources that both philosophers make available for the explanation of such desires, and what they take rationality to add to the motivational structure of human beings. In doing so, he finds conceptions of the mind that are coherent and deeply (...) integrated with both philosophers' views about such topics as the relation between body and soul, or the nature of the virtues.

The reliability of clinical practice guidelines has been disputed because guideline panel members are often burdened with financial conflicts of interest. Current recommendations for COI regulation advise not only detailed declaration but also active management of conflicts. To continuously assess COI declaration and management in German guidelines we established the public database LeitlinienWatch. We analyzed all German guidelines at the highest methodological level that included recommendations for pharmacological therapy according to five criteria: declaration and assessment of COI, composition of the (...) guideline development group, independence of the coordinators and lead authors, imposed abstentions because of COI and public external review. Each criterion was assessed using predefined outcome categories. Most guidelines contained a detailed declaration of COI. However, none of the guidelines provided full transparency of COI assessment results. The guideline group was composed of a majority of participants with COI in 55% of the guidelines, no guideline was free of participants with COI. Only 9% of guidelines had coordinators and lead authors without any financial COI. Most guidelines did not provide a rule for abstentions for participants with COI. In 21% of guidelines there was a rule, but abstentions were either not practiced or not documented, whereas in 7% partial abstentions and in 2% complete abstentions were documented. Two thirds of the guideline drafts were not externally reviewed via a public website. COI are usually documented in detail in German guidelines of the highest methodological level. However, considerable improvement is needed regarding active management of COI, including recruitment of independent experts for guideline projects, abstention from voting for participants with COI and external review of the guideline draft. We assume that the publicly available ratings on GuidelineWatch will improve the handling of conflicts of interest in guideline development. (shrink)

In this paper, we first classify different types of second opinions and evaluate the ethical and epistemological implications of providing those in a clinical context. Second, we discuss the issue of how artificial intelligent could replace the human cognitive labour of providing such second opinion and find that several AI reach the levels of accuracy and efficiency needed to clarify their use an urgent ethical issue. Third, we outline the normative conditions of how AI may be used as second opinion (...) in clinical processes, weighing the benefits of its efficiency against concerns of responsibility attribution. Fourth, we provide a ‘rule of disagreement’ that fulfils these conditions while retaining some of the benefits of expanding the use of AI-based decision support systems in clinical contexts. This is because the rule of disagreement proposes to use AI as much as possible, but retain the ability to use human second opinions to resolve disagreements between AI and physician-in-charge. Fifth, we discuss some counterarguments. (shrink)

We analyze investors’ perception and long-term effects of board gender diversity on firms’ stock market performance in an international setting. Our results, controlling for the endogenous nature of board compositions, indicate that female board representation neither improves nor reduces firms’ long-term stock performance. Hence, we argue that it is imperative to go beyond the conventional thinking in terms of the business case for gender diversity and broaden the perspective also to incorporate societal and ethical aspects in the strive to board (...) gender equality. Even more so, as our results show that it does not entail reduced shareholder value, which the literature on mandatory gender quotas commonly seems to suggest. (shrink)

Aristotle takes practical wisdom and arts or crafts to be forms of knowledge which, we argue, can usefully be thought of as ‘empiricist’. This empiricism has two key features: knowledge does not rest on grasping unobservable natures or essences; and knowledge does not rest on grasping logical relations that hold among propositions. Instead, knowledge rests on observation, memory, experience and everyday uses of reason. While Aristotle’s conception of theoretical knowledge does require grasping unobservable essences and logical relations that hold among (...) suitable propositions, his conception of practical and productive knowledge avoids such requirements and is consistent with empiricism.

An architect and architectural philosopher, Berlage created a series of buildings and a body of writings that probed the problems and possibilities of Modernism. His principal texts, given here in English for the first time, present a vital chapter in the history of European Modernism.

This paper explores the role and resolution of disagreements between physicians and their diagnostic AI-based decision support systems. With an ever-growing number of applications for these independently operating diagnostic tools, it becomes less and less clear what a physician ought to do in case their diagnosis is in faultless conflict with the results of the DSS. The consequences of such uncertainty can ultimately lead to effects detrimental to the intended purpose of such machines, e.g. by shifting the burden of proof (...) towards a physician. Thus, we require normative clarity for integrating these machines without affecting established, trusted, and relied upon workflows. In reconstructing different causes of conflicts between physicians and their AI-based tools—inspired by the approach of “meaningful human control” over autonomous systems and the challenges to resolve them—we will delineate normative conditions for “meaningful disagreements”. These incorporate the potential of DSS to take on more tasks and outline how the moral responsibility of a physician can be preserved in an increasingly automated clinical work environment. (shrink)

The central theme of this essay concerns the historical character of human nature and especially of human reason. This theme I will develop first of all by discussing briefly that aspect of the present-day philosophical debate, in which this theme takes pride of place. Thus, in the first section, I will try to show which predicament the participants of this debate face in the defense of their position. In the second section, I will discuss the main ideas of Herman Dooyeweerd’s (...) transcendental critique of theoretical thought. This critique, which Dooyeweerd himself considered to be a Christian critique on the whole tradition of philosophical thought, is closely tied up with the theme of this chapter. The problem of the historical character of human rationality — or in the words of Dooyeweerd, ‘the problem of historicism’ — formed for a large part the setting in which he developed his critique. Although I fully accord with the main thrust of Dooyeweerd’s philosophy and especially endorse that which motivated him in his transcendental critique, there are, nevertheless, elements in his conception which have dissatisfied me for a long time. His critique needs to be revised, in my opinion. In section three, I shall attempt such a revision, by taking as a starting point the idea of the ‘answering nature of humankind,’ an idea which I have worked out elsewhere. (shrink)

Ancient philosophical theories of soul are in many respects sensitive to ways of speaking and thinking about the soul psuchê] that are not specifically philosophical or theoretical. We therefore begin with what the word ‘soul’ meant to speakers of Classical Greek, and what it would have been natural to think about and associate with the soul. We then turn to various Presocratic thinkers, and to the philosophical theories that are our primary concern, those of Plato (first in the Phaedo, then (...) in the Republic), Aristotle (in the De Anima or On the Soul ), Epicurus, and the Stoics. These are by far the most carefully worked out theories of soul in ancient philosophy. Later theoretical developments — for instance, in the writings of Plotinus and other Platonists, as well as the Church Fathers — are best studied against the background of the classical theories, from which, in large part, they derive.

The project 'Facing Forward' started with a collaboration between five institutions: the Stedelijk Museum Amsterdam, the Amsterdam School for Cultural Analysis at the University of Amsterdam, De Appel arts centre, W139, the Stedelijk Museum Bureau Amsterdam and the art magazine Metroplis M. Having previously organized the lecture series and publications 'Right About Now: Art & Theory in the 1990s' (2005/2006) and 'Now is the Time: Art & Theory in the 21st Century' (2008/2009), the organizing committee decided to take the final (...) step in this timeline and turn its attention to the far horizon. Informed by a shared interest in the role that history, speculation, and utopianism play in the field of contemporary art and design (as well as the larger context of global, socio-economic and political developments), a selection of seven themes emerged from the conversations of the initial organizers. These would eventually shape the seven lecture and discussions events - collected in this volume of essays - publicized under the banner Art & Theory From a Future Perspective. A great number of internationally renowned speakers were invited to reflect on the proposed themes during often sold-out events, which were presented at the Oude Lutherse Kerk in Amsterdam in 2011/2012. Yet, however compelling our desire as organizers to go beyond the framework of contemporary events and the current interest, well-nigh obsession, with history, it is obviously an illusion to think that we can escape the past by means of a turn towards the future."--Page 8.

Mechanisms for QoS provisioning in communication networks range from flow-based resource reservation schemes, providing QoS guarantees, through QoS differentiation based on reservation aggregation techniques to adaptation of applications, compensating for incomplete reservations. Scalable, aggregation-based reservations can also be combined with adaptations for a more flexible and robust overall QoS provisioning. Adaptation is particularly important in wireless networks, where reservations schemes are more difficult to realize. It is widely accepted that usability of Cellular or Mobile IP can be largely improved if (...) adaptation is incorporated. Adaptation, in turn, depends on coding techniques involved and on user requirements. Those impose certain preferences and ordering relations on QoS hierarchies or degradation paths to be followed along when adaptation is performed. With the advent of MPEG4 coding techniques, more sophisticated adaptation schemes are more likely to be supported in the future. (shrink)

When heterogeneous players make strategic investment decisions in multi-stage contests, they might conserve resources in a current contest to spend more in a subsequent contest, if the degree of heterogeneity in the current contest is sufficiently large. We confirm these predictions using data from German professional soccer, in which players are subject to a one-match ban if they accumulate five yellow cards. Players with four yellow cards facing the risk of being suspended for the next match are less likely to (...) be fielded when the heterogeneity in the current match increases and more likely to receive a fifth yellow card in the current match when heterogeneity in the next match increases or heterogeneity in the next match but one decreases.

ABSTRACT:I argue that there are, according to Aristotle, two importantly different kinds of goals or ends in the domain of human agency and that one of these two kinds has been frequently, though not universally, overlooked. Apart from psychological goals, goals that agents adopt as their purposes, there are also, I submit, goals that actions have by being the kinds of actions they are and, in some cases, by occurring in the circumstances in which they do. These latter goals belong (...) to suitable actions whether or not agents adopt them as purposes and whether or not agents are aware of them. There is evidence both in Aristotle's ethical writings and in his discussion of chance and luck in Physics II.4–6 that he recognizes goals of this latter kind. (shrink)

When Immanuel Bekker, the editor to whom Aristotle owes his page numbers, travelled to Paris in search of manuscripts between 1810 and 1812, Theognis had been a mainstay of classical scholarship for many hundreds of years. Even so, the small tenth-century parchment volume Bekker discovered there came as a surprise. Not only did it contain a text of theTheognideawhich was four hundred years older than the earliest codex known so far; it also added an entirely new section of 176 lines. (...) Presented by the scribe as ‘book 2’ of theElegiac Poemsby Theognis, they revolved around the theme of pederastic love – until then a topic not usually associated with the moralist from Megara. In spite of their similarities to what had now turned into ‘book 1’, they were dismissed as a late forgery almost instantly after Bekker's 1815 edition. Although that view came to be challenged later and can now be considered obsolete, even van Groningen's first comprehensive commentary to theTheognidea, published in 1966 and not superseded since, breaks off where the second book would have begun. Until today, research on this part of the Theognidean corpus has not grown much beyond a trickle flowing at some distance from the classical mainstream. (shrink)

This paper contends that law is in essence an evolutionary phenomenon that can, and indeed should, be studied in the light of biological mechanisms. Law can be seen as an extended phenotype of underlying genes. In addition, legal systems can be seen as congruous to genetic mechanisms. Properties of genes have an impact on legal systems in a fractal-like manner. Hence, it is not surprising that notions of stability, replication, and reciprocity that are important in biological systems will also be (...) important in legal systems. As a result legal systems can be constructed in a way that is congruent with the genetic advantage of group members. Law, exposure, and punishment can diminish deviant behaviour and restore balance. Law may not be particularly subject to natural selection, but it will certainly be built on the foundations of natural selection. (shrink)
