A comprehensive, self-contained survey of the theory and applications of differential games, one of the most commonly used tools for modelling and analysing economics and management problems which are characterised by both multiperiod and strategic decision making. Although no prior knowledge of game theory is required, a basic knowledge of linear algebra, ordinary differential equations, mathematical programming and probability theory is necessary. Part One presents the theory of differential games, starting with the basic concepts of game theory and going on (...) to cover control theoretic models, Markovian equilibria with simultaneous play, differential games with hierarchical play, trigger strategy equilibria, differential games with special structures, and stochastic differential games. Part Two offers applications to capital accumulation games, industrial organization and oligopoly games, marketing, resources and environmental economics. (shrink)

Background: This study examined the cyberbullying experience and coping manners of adolescents in urban Vietnam and explored the mediating effect of different support to the associations between cyberbullying and mental health issues.Methods: A cross-sectional study was performed on 484 students at four secondary schools. Cyberbullying experience, coping strategies, psychological problems, and family, peer, and teacher support were obtained. Structural equation modeling was utilized to determine the mediating effects of different support on associations between cyberbullying and psychological problems.Results: There were 11.6 (...) and 28.3% of students who reported that they experienced and observed at least one cyberbullying act in the last 3 months, respectively. Among the victims, only 48.2% tried to stop the perpetrators. Meanwhile, the majority of observers belonged to the “Intervene” group who tried to report cyberbullying acts or help victims. Family support was found to partially mediate associations between cyberbullying experience and observation with levels of psychological problems among adolescents.Conclusion: The 3-month rate of cyberbullying experience and observation among urban adolescents aged 11–14 was low. However, current coping strategies against cyberbullying were not sufficient. Family support is an important factor that should be considered for designing interventions to mitigating the impacts of cyberbullying on the mental health of adolescents. (shrink)

Network reconfiguration is one of the most effective methods to reduce line power loss in the distribution system, which causes higher losses than the other parts of the power system. This paper proposes a modified symbiotic organisms search algorithm to solve the NR problem. For the purpose of enhancing the effectiveness of MSOS, the mutualism and parasitism strategies of the original symbiotic organisms search have been modified to create better new solutions. In the mutualism strategy, the so-far best solution is (...) updated immediately as soon as new solutions are created. In the parasitism strategy, the update is only implemented for the first half of control variables, whereas another half still remains unchanged. The comparison results between MSOS and SOS on twenty-five benchmark functions and different scales of test distribution systems with 14, 33, 69, and 119 nodes show that the improvement level of MSOS over SOS is significant with higher success rates and better quality of gained solutions. Similarly, MSOS also reaches better results than other methods in the literature. Consequently, MSOS can be a favorable method for determining the most appropriate configurations for the distribution systems. (shrink)

The ongoing coronavirus 2019 pandemic caused by the severe acute respiratory syndrome coronavirus 2 has resulted in a severe ramification on the global healthcare system, principally because of its easy transmission and the extended period of the virus survival on contaminated surfaces. With the advances in computer-aided diagnosis and artificial intelligence, this paper presents the application of deep learning and adversarial network for the automatic identification of COVID-19 pneumonia in computed tomography scans of the lungs. The complexity and time limitation (...) of the reverse transcription-polymerase chain reaction swab test makes it disadvantageous to depend solely on as COVID-19’s central diagnostic mechanism. Since CT imaging systems are of low cost and widely available, we demonstrate that the drawback of the RT-PCR can be alleviated with a faster, automated, and reduced contact diagnostic process via the use of a neural network model for the classification of infected and noninfected CT scans. In our proposed model, we explore the benefit of transfer learning as a means of resolving the problem of inadequate dataset and the importance of semisupervised generative adversarial network for the extraction of well-mapped features and generation of image data. Our experimental evaluation indicates that the proposed semisupervised model achieves reliable classification, taking advantage of the reflective loss distance between the real data sample space and the generated data.

As the market and civil society sectors reflect different core logics, non-governmental organisations (NGOs) that partner with companies need strategies to cope with these differences. This paper seeks to provide insight into the coping strategies of environmental NGOs that partner with corporations. We present an assessment framework to analyse the strategies of the Environmental Defense Fund and the World Wildlife Fund for Nature Netherlands as case studies. The analysis demonstrates that the strategic options for a partnering NGO are guided and (...) constrained by the choices the NGO makes with regard to its action strategy towards companies. Although individual NGOs manage to cope adequately with the challenges that the partnership trend poses to their organisations, we argue that the partnering trend also creates challenges for the NGO field as a whole.

This article presents findings from an interview study of human rights practitioners who assist relatives of the disappeared from Chechnya with their complaints before the European Court of Human Rights (ECtHR). These practitioners work for nongovernmental organizations (NGOs). The study contributes to the scant literature on NGO litigation before the ECtHR and to the social scientific literature on how human rights are actively practiced. It investigates the NGOs’ intermediary position between the ECtHR and the relatives of the disappeared in Chechnya. (...) Consequently, this article asserts that a significant aspect of this position lies in the practitioner’s capacity to mediate between an ambition to externalize local grievances to the ECtHR and the relatives’ hopes that the ECtHR can bring certainty to the uncertain loss of their disappeared relatives. From this position, several dilemmas emerge as to how international legal mechanisms can provide remedies following disappearances. (shrink)

We propose a new approach for tracing value change. Value change may lead to a mismatch between current value priorities in society and the values for which technologies were designed in the past, such as energy technologies based on fossil fuels, which were developed when sustainability was not considered a very important value. Better anticipating value change is essential to avoid a lack of social acceptance and moral acceptability of technologies. While value change can be studied historically and qualitatively, we (...) propose a more quantitative approach that uses large text corpora. It uses probabilistic topic models, which allow us to trace values that are latent. We demonstrate the approach for five types of value change in technology. Our approach is useful for testing hypotheses about value change, such as verifying whether value change has occurred and identifying patterns of value change. The approach can be used to trace value change for various technologies and text corpora, including scientific articles, newspaper articles, and policy documents. (shrink)

The Coronavirus disease pandemic of 2019 is a vast worldwide public health hazard, impacting people of all ages and socioeconomic statuses. Vaccination is one of the most effective methods of controlling a pandemic like COVID-19. This study aims to investigate the relationship between the number of vaccination injections and fear of COVID-19 and test whether beliefs benefit from vaccination COVID-19 mediate the effect of fear of COVID-19 on the number of vaccination injections. A total of 649 Vietnamese adults were enrolled (...) online to finish answering, including scales The Health Belief Model (HBM) and The Fear of COVID-19 (FCV-19S), consisting of 340 (52.4%) males and 309 (47.6%) females. The data were analyzed using variance, regression, and a simple mediation model. The total score of COVID-19 fear wasM= 22.26,SD= 5.49. Vietnamese fear of COVID-19 was at a medium level. Our results suggest that 18- to 20-year-olds are more fearful of COVID-19 than others. People who received the first dosage exhibited a greater fear of COVID-19 than those who received the second dose and were not inoculated. Additionally, the beliefs benefit of vaccination COVID-19 has a role in the relationship between the number of vaccination injections and fear of COVID-19. During the pandemic, adults in Vietnam are more afraid of COVID-19 than during prior outbreaks. Besides, the Vietnamese populace demonstrated a considerable demand for and high acceptability of the COVID-19 vaccine. The current study indicates that psychological counselors and therapists should counsel clients on the value of vaccination and address the fear of COVID-19 as public understanding of the benefits of vaccines increases. To further clarify the effect of this issue on the correlation between fear of COVID-19 and the number of vaccinations, the results of this study indicate that the existing vaccine communication factor for COVID-19 vaccination should be modified to increase confidence in the benefits of immunization.

Subliminal primes are assumed to produce weaker and short-lived effects on subsequent behavior compared to clearly visible primes. However, this difference in priming effect may be due to differences in signal strength, rather than level of awareness. In the present study we manipulated prime discriminability by using metacontrast masks and pseudomasks, while keeping the prime strength equal. This manipulation resulted in large differences in discriminability of the primes. However, both immediate response priming and long-term response priming was equal for (...) the poorly discriminable and well discriminable primes, and equal for groups that differed markedly in terms of how well they could discriminate the primes. Our findings imply that discriminability of information is independent of both the immediate and long-term effects that information can have on behavior. (shrink)

This article describes the long-term trends in marital status mortality differences in the Netherlands using a unique dataset relating to the period 1850–1970. Poisson regression analysis was applied to calculate relative mortality risks by marital status. For two periods, cause-of-death by marital status could be used. Clear differences in mortality by marital status were observed, with strongly increasing advantages for married men and women and a relative increase in the mortality of widowed compared with non-married people. Excess mortality among (...) single and formerly married men and women was visible in many cause-of-death categories, and this became more widespread during the last decades of the nineteenth century. Hypotheses are formulated that might explain why married men and women underwent a stronger decrease in mortality up until the end of World War II. (shrink)

How on Earth can Humans be perfect? The striving for perfection has always occupied a central place in ancient Greek culture. This dynamics urged the Greeks on to surpass themselves in different fields, from sculpture and architecture over athletics to philosophy. In this volume, an international group of scholars examines how the ideal of perfection was conceived and pursued in Late Antiquity, both within philosophical circles and Christianity. Their studies yield a fascinating panorama of various attempts to bridge the unbridgeable (...) and assimilate our frail, imperfect human nature as far as possible to divine perfection. (shrink)

This article examines Grotius’ lifelong support for Dutch expansion overseas. As noted in other publications of mine, Grotius cooperated closely with the directors of the Dutch East India Company (VOC) in the years 1604–1615. Right up to his arrest for high treason in August 1618, he contributed towards Dutch government discussions about the establishment of a West India Company (WIC). Three years of imprisonment at Loevestein Castle and, following his escape, long years of exile could not weaken his dedication (...) to the cause. His relatives in Holland, in particular his brother Willem de Groot and his brother-in-law Nicolaas van Reigersberch, kept him up-to-date on the fortunes of the VOC and WIC. His expertise on maritime affairs was in high demand. For example, Cardinal Richelieu invited him in November 1626 to become actively involved in the establishment of a French East India Company. As itinerant ideologue of empire, Grotius sought to further his own career and those of his nearest family members, without damaging the interests of the United Provinces. Through Willem de Groot and Nicolaas van Reigersberch, he provided informal advice on Dutch imperial policy to the VOC directors and government officials in The Hague. He was rewarded with the appointment of his brother and his second son, Pieter de Groot, as VOC lawyers (ordinaris advocaten) in 1639 and 1644, respectively. They served as his proxies in diplomatic disputes involving the VOC, the States General and the Portuguese ambassador in autumn 1644, when Pieter and Willem de Groot wrote a defense of VOC claims to the cinnamon-producing areas of Ceylon (modern-day Sri Lanka), liberally citing De Jure Belli ac Pacis. Grotius’ vision of empire hardly changed in the course of 40 years. In his view, the Dutch had gone to the Indies as merchants, not conquerors, and should regulate themselves according to natural law and the law of nations. Thus he contributed to the creation of two political orders, one for Europe and one for the Indies. European diplomatic relations counted for little beyond the Line. VOC and WIC officials could act as judges and executioners in their own cause, without reference to indigenous rulers, other colonial powers, or even the political authorities back home. (shrink)

Aim:This study explores experiences of patients suffering from Korsakoff’s syndrome. It contributes to improved reflection on the value of patient knowledge.Background:An ethics of care perspective states the importance of moving to patients in their vulnerable state of being, and to figure out patients’ individual needs necessary to provide good care. The information given by patients suffering from Korsakoff’s syndrome might be mistaken, invented and even not true. The value of these patients’ experiences and knowledge had not been researched to date.Method:Data (...) from six in-depth interviews were analysed concurrently through the constant comparative method.Ethical considerations:The principles of voluntariness, confidentiality and anonymity were respected during the research process.Findings:Four important themes within patients’ knowledge emerged: health condition, involuntary admission into the nursing home, the daily routine and interpretation of the caring abilities of healthcare professionals. The findings show that our respondents were able to provide a window into their inner perspective.Conclusion:This study deepens our understanding of the value of patient knowledge in situations where patients see the world in a different manner as do healthcare professionals. The conversations revealed personal subjective knowledge which our respondents create and live by. Healthcare professionals are encouraged to discover and affirm the understandings of these patients, and not be prepossessed due to the diagnosis or general nursing home rules. Understanding patients’ unique knowledge through appreciation of the complexity and richness of different views on the situation can assist to give a more humane response to individual needs and pain. Health staff in healthcare institutions are encouraged to evaluate the – unintended – effect of rigidly applied nursing home rules, and the government is challenged to rethink its policy about care, and provide more resources permitting relational care that nurtures the dignity of patients suffering from Korsakoff’s syndrome.

Modern logic is undergoing a cognitive turn, side-stepping Frege’s ‘antipsychologism’. Collaborations between logicians and colleagues in more empirical fields are growing, especially in research on reasoning and information update by intelligent agents. We place this border-crossing research in the context of long-standing contacts between logic and empirical facts, since pure normativity has never been a plausible stance. We also discuss what the fall of Frege’s Wall means for a new agenda of logic as a theory of rational agency, and (...) what might then be a viable understanding of ‘psychologism’ as a friend rather than an enemy of logical theory.

One of the key concepts of Paul Ricoeur’s hermeneutics is the notion of distanciation. In this article we show that Ricoeur introduces this notion as a correction of Heidegger’s focus on being-in and Gadamer’s emphasis on belonging . Ricoeur argues that distanciation does not lead to the uprooting of our belonging to a tradition. Rather, distanciation is an integral part of the dynamics that constitutes tradition. We discuss the different senses in which Ricoeur understands distanciation as a positive and productive (...) aspect of tradition. In particular, we discuss the ontological aspect of distanciation. In his discussion of both the long way of hermeneutics and the creative dimension of distanciation in fiction, Ricoeur argues that it is distanciation that opens up the possibility of understanding our own being-in-the-world. This involvement of distanciation in the disclosure and understanding of being allows us to show that distanciation determines what “kind” of being is understood: what is interpreted in hermeneutics and disclosed in poetics is never being as such, but “being-interpreted” and “being-as,” respectively. This leads us to a description of the difference between Ricoeur’s and Heidegger’s thought concerning the ontological dimension of their hermeneutics. (shrink)

Over the past 20 years business ethics in Europe witnessed a remarkable growth. Today business ethics is faced with two challenges. The first comes from the social sciences and consultants who have both reclaimed the topics of business ethics, regretfully often at the loss of the proper ethical perspective. The second comes from the remarkable rise of corporate social responsibility which has pushed aside the mainstream business ethics methodology with its emphasis on moral deliberation by the individual. These challenges can (...) be tackled by an institutional transformation in business ethics that links up to the long-standing European tradition of institutional analysis of the market. The second remedy is an enlargement of the research agenda in business ethics by coming closer to other parts of applied ethics where the business ethics view is at this moment grossly neglected.

The traditional use of ergodic theory in the foundations of equilibrium statistical mechanics is that it provides a link between thermodynamic observables and microcanonical probabilities. First of all, the ergodic theorem demonstrates the equality of microcanonical phase averages and infinite time averages (albeit for a special class of systems, and up to a measure zero set of exceptions). Secondly, one argues that actual measurements of thermodynamic quantities yield time averaged quantities, since measurements take a long time. The combination of (...) these two points is held to be an explanation why calculating microcanonical phase averages is a successful algorithm for predicting the values of thermodynamic observables. It is also well-known that this account is problematic.

This survey intends to show that ergodic theory nevertheless may have important roles to play, and it explores three other uses of ergodic theory. Particular attention is paid, firstly, to the relevance of specific interpretations of probability, and secondly, to the way in which the concern with systems in thermal equilibrium is translated into probabilistic language. With respect to the latter point, it is argued that equilibrium should not be represented as a stationary probability distribution as is standardly done; instead, a weaker definition is presented.

This article discusses how sequential sampling models can be integrated in a cognitive architecture. The new theory Retrieval by Accumulating Evidence in an Architecture (RACE/A) combines the level of detail typically provided by sequential sampling models with the level of task complexity typically provided by cognitive architectures. We will use RACE/A to model data from two variants of a picture–word interference task in a psychological refractory period design. These models will demonstrate how RACE/A enables interactions between sequential sampling and (...) class='Hi'>long-term declarative learning, and between sequential sampling and task control. In a traditional sequential sampling model, the onset of the process within the task is unclear, as is the number of sampling processes. RACE/A provides a theoretical basis for estimating the onset of sequential sampling processes during task execution and allows for easy modeling of multiple sequential sampling processes within a task.

The combination of logic and game theory provides a fine-grained perspective on information and interaction dynamics, a Theory of Play. In this paper we lay down the main components of such a theory, drawing on recent advances in the logical dynamics of actions, preferences, and information. We then show how this fine-grained perspective has already shed new light on the long-term dynamics of information exchange, as well as on the much-discussed question of extensive game rationality.

This article describes compassion as perceived within the relationship between nurses and older persons with a chronic disease. The aim of the study is to understand the benefit of compassion for nursing practice within the context of long-term care. The design of the study involves a qualitative analysis of in-depth interviews with nurses and patients in three different care-settings. Results show the nature of compassion in seven dimensions: attentiveness, listening, confronting, involvement, helping, presence and understanding. Analysis of the data (...) also shows in what way opinions of participants relate to issues raised in a previous literature study, for example the difference between pity and compassion. The conclusion states that compassion is a valuable process which motivates patients as well as nurses to cooperate in achieving relevant outcomes of care. The discussion involves some methodological issues. For one thing, further confirmation of the dimensions found is recommended. (shrink)

Increased scrutiny of corporate legitimacy has sparked an interest in “historic corporate social responsibility”, or the mechanism through which firms take responsibility for past misdeeds. Extant theory on historic CSR implicitly treats corporate engagement with historical criticism as intentional and dichotomous, with firms choosing either a limited or a high engagement strategy. However, this conceptualization is puzzling because a firm’s engagement with historic claims involves organizational practices that managers don’t necessarily control; hence, it might materialize differently than anticipated. Furthermore, multiple (...) motivations could jointly affect managers’ approach to organizational history, especially when dealing with conflicting stakeholder demands, rendering it difficult to historicize consistently. Examining the relationship between the legitimacy of critical historic claims, corporate engagement with these claims and corporate legitimacy, the present paper performs a historical case study of the Hudson’s Bay Company’s (HBC) long term use of history in stakeholder relations. The data suggest that under conflicting internal and external pressures, the HBC’s engagement with historical criticism became “sedimented” over time, involving both open and stakeholder-inclusive practices of “history-as-sensemaking” and instrumental “history-as-rhetoric”. Enriching understanding of corporate-stakeholder interaction about the past, this finding may stimulate its generation of social value and corporate legitimacy. (shrink)

In the recently published Papyrus Bodmer 30 one of the six poems deals with the story of Genesis 22. At many places the poem drastically deviates from the biblical text, and the editors of the papyrus are insufficiently aware of the background of these deviations.

It is the very specific ‘Wirkungsgeschichte’ (...) of Gen. 22 that explains most of the poem’s specifics. (shrink)

This Handbook documents the main trends in current research between logic and language, including its broader influence in computer science, linguistic theory and cognitive science. The history of the combined study of Logic and Linguistics goes back a long way, at least to the work of the scholastic philosophers in the Middle Ages. At the beginning of this century, the subject was revitalized through the pioneering efforts of Gottlob Frege, Bertrand Russell, and Polish philosophical logicians such as Kazimierz Ajdukiewicz. (...) Around 1970, the landmark achievements of Richard Montague established a junction between state-of-the-art mathematical logic and generative linguistic theory. Over the subsequent decades, this enterprise of Montague Grammar has flourished and diversified into a number of research programs with empirical and theoretical substance. This appears to be the first Handbook to bring logic-language interface to the fore. Both aspects of the interaction between logic and language are demonstrated in the book i.e. firstly, how logical systems are designed and modified in response to linguistic needs and secondly, how mathematical theory arises in this process and how it affects subsequent linguistic theory. The Handbook presents concise, impartial accounts of the topics covered. Where possible, an author and a commentator have cooperated to ensure the proper breadth and technical content of the papers. The Handbook is self-contained, and individual articles are of the highest quality. (shrink)

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

Robust moral rationalism has long been regarded as incompatible with the Humean Theory of Motivation which requires desires to ground motives. Recently this orthodoxy has been challenged on the ground that rationality itself might require certain desires. This strategy does not remove the tension between rationalism and the Humean Theory. If rationalism is correct, new normative beliefs should engender new motives - motives not grounded in a means-ends fashion in rationally required existing desires. Thus the motivational responses we should (...) expect would be ruled out by the Humean Theory, even when supplemented by rationally required desires. Anti-Humeans about rationality should not be Humeans about motivation. (shrink)

Is the being in an irreversible persistent vegetative state as the result of a horrible accident numerically identical to the human person, Lindsay, who existed before the accident? Many proponents of Thomistic metaphysics have argued that Aquinas’s answer to this question must be “yes.” In particular, it seems that Aquinas’s commitment to both Aristotelian hylomorphism and the unity of substantial form (viz., that each body/soul composite possesses one and only one substantial form) entails the position that the human person remains (...) alive as long as biological life persists. I argue, however, that although Aquinas does possess a deeply integrated account of human nature and is indeed committed to the claim that the person, Lindsay, exists as long as Lindsay’s body lives, there is good reason to suppose that he also holds that the body in the PVS is not Lindsay’s body in anything more than an equivocal sense.

The impact of science on ethics forms since long the subject of intense debate. Although there is a growing consensus that science can describe morality and explain its evolutionary origins, there is less consensus about the ability of science to provide input to the normative domain of ethics. Whereas defenders of a scientific normative ethics appeal to naturalism, its critics either see the naturalistic fallacy committed or argue that the relevance of science to normative ethics remains undemonstrated. In this (...) paper, we argue that current scientific normative ethicists commit no fallacy, that criticisms of scientific ethics contradict each other, and that scientific insights are relevant to normative inquiries by informing ethics about the options open to the ethical debate. Moreover, when conceiving normative ethics as being a nonfoundational ethics, science can be used to evaluate every possible norm. This stands in contrast to foundational ethics in which some norms remain beyond scientific inquiry. Finally, we state that a difference in conception of normative ethics underlies the disagreement between proponents and opponents of a scientific ethics. Our argument is based on and preceded by a reconsideration of the notions naturalistic fallacy and foundational ethics. This argument differs from previous work in scientific ethics: whereas before the philosophical project of naturalizing the normative has been stressed, here we focus on concrete consequences of biological findings for normative decisions or on the day-to-day normative relevance of these scientific insights.

The “testing effect” refers to the finding that after an initial study opportunity, testing is more effective for long‐term retention than restudying. The testing effect seems robust and is a finding from the field of cognitive science that has important implications for education. However, it is unclear whether this effect also applies to the acquisition of problem‐solving skills, which is important to establish given the key role problem solving plays in, for instance, math and science education. Worked examples are (...) an effective and efficient way of acquiring problem‐solving skills. Forty students either only studied worked examples (SSSS) or engaged in testing after studying an example by solving an isomorphic problem (STST). Surprisingly, results showed equal performance in both conditions on an immediate retention test after 5 min, but the SSSS condition outperformed the STST condition on a delayed retention test after 1 week. These findings suggest the testing effect might not apply to acquiring problem‐solving skills from worked examples. (shrink)

Philosophical theories about reduction and integration in science are at variance with what is happenign in science. A realistic approach to science show that possibilities for reduction and integration are limited. The classical ideal of a unified science has since long been rejected in philosophy. But the current emphasis on interdisciplinary integration in philosophy and in science shows that it survives in a different guise. It is necessary to redress the balance, specifically in biology. Methodological analysis shows that many (...) of the grand interdisciplinary theories involving biology actually represent pseudo-integration covered up by inappropriate, overgeneral concepts. Integrationism is not bad, but it must be kept within reasonable bounds. If the present analysis is appropriate, there will have to be fundamental changes in research strategy both in science and in the philosophy of science. (shrink)

In cognitive science, long-term anticipation, such as when planning to do something next year, is typically seen as a form of ‘higher’ cognition, requiring a different account than the more basic activities that can be understood in terms of responsiveness to ‘affordances,’ i.e. to possibilities for action. Starting from architects that anticipate the possibility to make an architectural installation over the course of many months, in this paper we develop a process-based account of affordances that includes long-term anticipation (...) within its scope. We present a framework in which situations and their affordances unfold, and can be thought of as continuing a history of practices into a current situational activity. In this activity affordances invite skilled participants to act further. Via these invitations one situation develops into the other; an unfolding process that sets up the conditions for its own continuation. Central to our process account of affordances is the idea that engaged individuals can be responsive to the direction of the process to which their actions contribute. Anticipation, at any temporal scale, is then part and parcel of keeping attuned to the movement of the unfolding situations to which an individual contributes. We concretize our account by returning to the example of anticipation observed in architectural practice. This account of anticipation opens the door to considering a wide array of human activities traditionally characterized as ‘higher’ cognition in terms of engaging with affordances. (shrink)

The long stagflation in the nineteen-seventies broke the Keynesian hold on economic policy. Last year we witnessed the spectacular unraveling of neo-liberal policies of manipulating money and credit. While these episodes might be studied to explain the specific weaknesses and errors of each of the two policy paradigms that have dominated in the West after the Second World War, this lecture highlights the ideas and presuppositions that remained in place throughout the whole period. Despite the alliance that once existed (...) between libertarians and classical liberals, on the one hand, and neo-liberals, on the other hand, the latter did not have sufficiently coherent conceptions of freedom and free markets to produce a true alternative for the Keynesian idea of a scientifically managed economy as a utilitarian and pragmatic approach to the utopian goal of the greatest happiness for the greatest number, i.e., complete well-being for all.

In April 2002 a new law regarding euthanasia came into effect in the Netherlands. This law holds that euthanasia remains a criminal offence unless it is performed by a physician who acts according to six specified rules of due care and reports the case to a review committee. The six rules of due care are similar to those of the previous regulation and are largely based on jurisprudence. Completely new, however, is the article concerning a competent patient who has written (...) an advance directive requesting euthanasia under certain circumstances. The law stipulates that a physician may act according to that written request, as long as he or she fulfils all other rules of due care. The author defends the view that these requests are neither feasible nor ethically justifiable, and presents both moral and practical arguments for this, claiming that for consistency reasons one cannot act on the basis of a written statement and fulfil the other rules of due care at the same time. The author also examines a difficult case of a demented, severely depressed woman who had written a living will requesting euthanasia before she became demented. (shrink)

Background Clients are invited to play a role in decisions about their care. Collaborative deliberation comprises constructive engagement, recognition of alternative actions, comparative learning, construction and elicitation of preferences and preference integration. Collaborative deliberation between clients and professionals is a process that requires an interest in each other, sharing of views on alternatives and preferences and integrating into decisions. The aim is to gain insight into collaborative deliberation in consultations and the clients’ perception of arranging long-term care. Design A (...) descriptive qualitative study to explore collaborative deliberation in consultations between clients and professionals. Six organisations providing long-term care were included. Data collection of nine clients involved observations of consultation with field notes and audio-records, interviews with clients and professionals shortly and 3–6 months after the consultation and questionnaires to collect background information. The data were analysed by deductive content analysis. Findings Constructive engagement was visible in all consultations. Clients and professionals showed respect, empathy and curiosity towards each other. In most consultations, two or more alternative actions are recognised and discussed. Comparative learning appears to be two sided, the client and the professional learn from each other's knowledge and experiences. Construction and elicitation of preference, and preference integration, seems to be present, but difficult to recognise in all consultations. Discussion/conclusion Although all propositions could be identified, there seems room for improvement in preference elicitation and integration of these preferences in the discussions on courses of action. Assistance seems needed with preference elicitation, both for the clients and for the professional. (shrink)

This study aims to contribute to emerging human-robot interaction research by adding longitudinal findings to a limited number of long-term social robotics home studies. We placed 70 robots in users’ homes for a period of up to six months, and used questionnaires and interviews to collect data at six points during this period. Results indicate that users’ evaluations of the robot dropped initially, but later rose after the robot had been used for a longer period of time. This is (...) congruent with the so-called mere-exposure effect, which shows an increasing positive evaluation of a novel stimulus once people become familiar with it. Before adoption, users focus on control beliefs showing that previous experiences with robots or other technologies allows to create a mental image of what having and using a robot in the home would entail. After adoption, users focus on utilitarian and hedonic attitudes showing that especially usefulness, social presence, enjoyment and attractiveness are important factors for long-term acceptance.

Questions are triggers for explicit events of ‘issue management’. We give a complete logic in dynamic-epistemic style for events of raising, refining, and resolving an issue, all in the presence of information flow through observation or communication. We explore extensions of the framework to multi-agent scenarios and long-term temporal protocols. We sketch a comparison with some alternative accounts.

Just as war can be viewed as continuation of diplomacy using other means, computational semantics is continuation of logical analysis of natural language by other means. For a long time, the tool of choice for this used to be Prolog. In our recent textbook we argue (and try to demonstrate by example) that lazy functional programming is a more appropriate tool. In the talk we will lay out a program for computational semantics, by linking computational semantics to the general (...) analysis of procedures for social interaction. The talk will give examples of how Haskell can be used to begin carrying out this program. (shrink)

For our purposes it is convenient to divide the history of Europe into three periods. The first spans about a thousand years, from 500 BC, when Athens began to emerge as the dominant intellectual and cultural centre of Greece, to AD 500. It is the period of antiquity, of Ancient Greece and Ancient Rome. The second period, also a millennium long, from AD 500 to AD 1500, is that of Christian Europe. It began after the collapse of the Western (...) Empire, which is officially dated in 476. In that year the Germanic general Odoaker deposed the last Roman emperor and did not even bother to lay claim to the imperial throne. The Christian faith and its church filled the gap left by the disappearance of the imperial systems of administration, organisation and communication. The period ended when the Roman Church was successfully challenged by religious reformers, a new scientific and humanistic spirit agitated the intellectual scene, and European monarchs embarked on a policy of absolutism at home and of conquering the newly discovered continents in search of riches and colonies. Thus, AD 1500 is a convenient date to mark the beginning of the period of modernity, which continues to this day. On the next pages the reader will find an outline of European history, with marginal references to important thinkers and currents of thought. The outline lists in a rough chronological order some of the major events and transformations that have played a part in the genesis of the world in which we now live. The focus throughout is on the European continent, but when we get to the nineteenth and the twentieth century, it will be necessary to refer to what happened elsewhere. (shrink)
