In der niederländischen Kultur werden komplexe moralische Probleme oftmals mit einem pragmatischen und prozeduralen Verfahren statt mit einem prinzipiellen Zugang angegangen. Die Debatte um Entscheidungen am Lebensende, die dem Sterbehilfegesetz von 2002 vorausging, ist ein Beispiel für diese Praxis. Auch die Befassung der Niederlande mit der „terminalen Sedierung“, die als neue Phase in der Diskussion um Entscheidungen am Lebensende betrachtet werden kann, folgt den Prinzipien des „Poldermodells“. Gesellschaftliche und politische Gruppierungen kooperieren, um eine gemeinsame Lösung zu finden angesichts der Tatsache, (...) dass terminale Sedierung unterschiedliche Praktiken und entsprechend unterschiedliche moralische Implikationen beinhaltet.

Many social situations require a mental model of the knowledge, beliefs, goals, and intentions of others: a Theory of Mind (ToM). If a person can reason about other people’s beliefs about his own beliefs or intentions, he is demonstrating second-order ToM reasoning. A standard task to test second-order ToM reasoning is the second-order false belief task. A different approach to investigating ToM reasoning is through its application in a strategic game. Another task that is believed to involve the application of (...) second-order ToM is the comprehension of sentences that the hearer can only understand by considering the speaker’s alternatives. In this study we tested 40 children between 8 and 10 years old and 27 adult controls on (adaptations of) the three tasks mentioned above: the false belief task, a strategic game, and a sentence comprehension task. The results show interesting differences between adults and children, between the three tasks, and between this study and previous research. (shrink)

Recent scholarship has firmly established the similarities between Arendt and Foucault, in particular with regard to the dangers of late-modern social processes. Yet, few have compared their accounts of resistance. This paper argues that although Foucault offers the more comprehensive account, it omits the encounter with the other as unique and unfathomable, which is central to Arendt’s. This omission is particularly striking given the authors’ shared belief that the danger of ‘the social’ and ‘governmentality’ lies in atomizing individuals and barring (...) the development of a singular style of being, and their allusion to friendship and solidarity as sites of resistance. Drawing on Arendt, I show how Foucault restricts his thematization of solidarity and friendship to a reflexive praxis of the subject on her own limits, and argue instead for the relational dimension of resistance. I start by reconstructing their converging analysis of biological racism. I then continue with a discussion of resistance in Arendt, which she develops in response to the Shoah. More specifically, she provides a concept of solidarity and friendship that I draw on to extend Foucault’s analysis of the transnational solidarity among the governed in fighting for their rights vis-à-vis their governments; and of friendship in the context of his interrogation of the LGBT-movement.

Approaching Simone de Beauvoir’s feminism and social commentary as a resource to understand our current crises, Beauvoir and Politics: A Toolkit brings together established and emerging scholars to apply her insights to gender studies, political philosophy, decolonisation, intellectual history, age theory, and critical phenomenology. The essays in this collection start from key concepts in Beauvoir’s oeuvre and relate them to contemporary debates, asking how her notion of ambiguity speaks to lived experiences that have been highly politicized in recent years, such (...) as pregnancy, old age, sexual violence, and the exposure of black and brown bodies to police violence; how myths inform our notions of collective, national identities, as well as notions of masculinity and femininity; and how she provides conceptual tools that help to theorize the various political strategies that are used to challenge gendered and racialized systems of oppression. These and other issues are central to this critical appraisal of Beauvoir’s legacy, demonstrating the contemporary relevance of her thought as it diagnoses the present and looks toward change for a better future. This book will be of great interest to undergraduate and postgraduate students looking to engage with the political content of Simone de Beauvoir’s work and the timely application of her ideas.

This paper discusses the empirical, Application Programming Interface -based analysis of very large Facebook Pages. Looking in detail at the technical characteristics, conventions, and peculiarities of Facebook’s architecture and data interface, we argue that such technical fieldwork is essential to data-driven research, both as a crucial form of data critique and as a way to identify analytical opportunities. Using the “We are all Khaled Said” Facebook Page, which hosted the activities of nearly 1.9 million users during the Egyptian Revolution and (...) beyond, as empirical example, we show how Facebook’s API raises important questions about data detail, completeness, consistency over time, and architectural complexity. We then outline an exploratory approach and a number of analytical techniques that take the API and its idiosyncrasies as a starting point for the concrete investigation of a large dataset. Our goal is to close the gap between Big Data research and research about Big Data by showing that the critical investigation of technicity is essential for empirical research and that attention to the particularities of empirical work can provide a deeper understanding of the various issues Big Data research is entangled with.

The study of complexity in chronic care is an emergent discipline that has not yet developed a consistent theoretical framework. Thinking in the field of complexity encompasses complexity science and complexity theories, which represent a convergence of different types of ideas and theories that focus on the interactions of individual parts that make up a complex system. In this context, an important distinction is to be made between "complex" and "complicated." If a system—despite the fact that it may consist of (...) a huge number of components— can be given a complete description in terms of its individual constituents, such a system is merely complicated. An example could be computers. In a complex system, on the .. (shrink)

For Hannah Arendt, authority is the shape educational responsibility assumes. In our time, authority in Arendt’s sense is under pressure. The figure of Greta Thunberg shows the failure of adult generations, taken collectively, to take responsibility for the world and present and future generations of newcomers. However, in reflecting on Arendt’s use of authority, we argue that her account of authority also requires amendments. Arendt’s situating of educational authority in-between past and future adequately captures its temporal dimension. We make explicit (...) another, spatial, dimension: authority in-between world and earth. Arendt’s neglect of the material earth also has implications for the relational dimension of authority. Arendt’s authority depends on a dichotomy between the private and the public sphere. This is problematic. First, we agree with Arendt’s feminist critics that the personal can be made into the site of the political. Second, we point once more to Thunberg, the child, taking the public stage, thereby contesting the division between public and private. In response, we situate the relational dimension of authority in-between private and public. The three dimensions of educational authority taken together imply that it is situated in-between domains that cannot be reduced to each other or taken as absolutes: past and future, world and earth, and the private and public sphere. This brings us to our concept of ambiguous authority, which expresses the Arendtian nature of our reflections and the ways in which we seek to renew her original insights on educational authority.

A scheme of analysis for separatism is proposed. Its purpose is twofold: to indicate the essential factors in a separatist process, and to explain the waves of active and « dead » separatist activity.The central idea is the distinction between three dimensions in the separatist process : conflict, mobilization and collective action. Both dimension on its own is determined by certain factors. Conflict depends on contradictions of identity and interest structure between people and nation. Mobilization is primarily a function of (...) the social, economic and political opportunities of the people as against the nation. Collective action is the result of the presence, strength and behaviour of the elite and social movement in people and nation.Evolution from one dimension to the next one depends upon the factors of the dimensions involved and on a) the policy of the nation and b) the societal changes caused by the modernization process.Finally one can explain inactive and active periods by verifying the presence or absence of these nine factors. It seems then that there are false and real « dead » periods, and that some separatist activity has a sound basis white other has not. (shrink)

Despite major institutional and political changes in the Belgian political system in the last 25 years, the electoral organization has been very stable.The adaptations of the electoral organization have even been less in the province of Brabant, although the politica! developments have caused there additional problems. Brabant's electoral constituencies contain a rather strange mixture of heterogeneous electorates : a constituency, which consists of the bilingual capital Brussels as welt as several Flemish communes, a unilingual Walloon constituency, a unilingual Flemish constituency. (...) The proposed solutions for Brabant's complex situation can be summarized into six alternative systems of electoral organization, concentrating either on the functioning of the system of provincial allotment, or on a radical redrawing of the boundaries of the electoral constituencies.The impact of the six alternatives on the seats distribution among the political parties is rather restricted. The shifts of seats inside the parties are more striking than between the parties. Alternatives IV and VI cause the largest reallocation of seats between the parties, whereas alternatives II, III and V result in only minor changes. (shrink)

This essay aims to correct the widely-held view that Arendt is hostile to the body due to its physical needs. By focusing on two modes of corporeality that are distinguished by the production of bodily substances—the digestive body and the crying body—I argue that Arendt (1) deployed various notions of corporeality that thematize, in different ways, the uncontrollability our bodies; and (2) argues for the affirmation of this unmasterablity because it corresponds to the conditioned nature of human existence. Firstly, Arendt (...) criticized the Greek, narcissistic aspiration toward physical beauty, exemplified in the figure of Achilles, for its attempt to subjugate the digestive body to a preconceived end—a criticism that equally applies to Connolly’s plea for strategically altering our affects. Secondly, Arendt’s appreciation of Homer’s description of a crying Odysseus shows that the acknowledgment of events constitutive of one’s life consists in a publicly visible somatic reaction.

A complete reconstruction of Lehmer’s ENIAC set-up for computing the exponents of p modulo two is given. This program served as an early test program for the ENIAC (1946). The reconstruction illustrates the difficulties of early programmers to find a way between a man operated and a machine operated computation. These difficulties concern both the content level (the algorithm) and the formal level (the logic of sequencing operations).

This study investigates the likelihood of director turnover following opportunistic insider selling. Given that opportunistic insider selling may be costly to a firm due to potential legal risk and firm legitimacy concerns, we hypothesize that directors engaging in this type of transactions have a higher likelihood of subsequently leaving the board. Using archival data of 11,409 directors in 2280 US firms from 2005 to 2014, univariate comparisons show that directors engaging in opportunistic insider selling are about 8% more likely to (...) exit their firms’ board compared to directors not engaging in this behavior. Furthermore, multivariate results show that the likelihood of director departure following opportunistic insider selling is higher for some directors but not all. Specifically, directors who are especially valuable to the board or costly to replace do not seem to experience elevated levels of turnover. Interestingly, this difference in director turnover is only observed in smaller firms. We find that in larger firms, the likelihood of director turnover following opportunistic insider selling does not depend on director characteristics. As such, results seem to suggest that boards do not homogeneously self-regulate in this context as some directors seem to be shielded from turnover following unethical behavior. (shrink)

Both love and politics name relations, according to Arendt, in which a subject is constituted as a unique person. Following up on this suggestion, I explore how love gives rise to a conception of personhood that temporarily suspends the public judgments and social prejudices that reduce the other to their actions or to their social identity. I do so by tracing a similar movement in the various tropes of Arendt’s phenomenology of love: the retreat away from the collective world into (...) the intimacy of love, followed by the necessary return to the world and the end of love. This exploration casts a new—and surprisingly positive—light on some key notions in Arendt’s thought, such as the body, the will, and life. However, Arendt disregards that love, as De Beauvoir argued, requires a constant effort in restraining our tendency to reduce the lover to their social identity. (shrink)

ABSTRACT The influence by Walter Benjamin on Arendt’s notion of narrativity has been firmly established, but little research has been done to contextualize his influence. This paper fill this lacunae by showing how, like Benjamin, Arendt was concerned to deploy a form of writing history that ensures the individuality of its agents, but that as she articulated her notion of the public space, the redemptive, messianic elements in his historiography were replaced with a secular and political mode of remembrance. The (...) notion of the public space and the accompanying secularization of Benjamin’s redemptive history should not be understood as the result of a linear development, but rather as responses to contemporary political events, of which I focus on three: (1) her early writings on totalitarianism, in which she tries to come to terms with the Shoah; (2) her reflections on the Greek city state, in which she criticizes the instrumentalization of politics in post-war democracies such as West-Germany; and finally, (3) the court room as a space for storytelling and the contestation over the history of anti-Semitism during the Eichmann trial.

Resistance and Techniques of Virginity: A Feminist Reading of The Confessions of the Flesh What is the feminist relevance of Foucault’s posthumously published Confessions of the Flesh? This question is part of a larger debate on the usefulness of the later Foucault in conceptualizing resistance against patriarchal power relationships. This paper follows those who argue in favor of the feminist potential of his concepts of freedom and care for the self, in particular the notions of ascesis and askesis. I argue (...) that resistance against gendered norms is explicit in his discussion of counter-conduct (1978), which he links to late-medieval mysticism and to excessive, physical experiences. Both the gender-component and the excessive corporeal experiences disappear, however, from his later concept of askesis, which suggests that Foucault’s omission of women coincides with a displacement of the suffering body as a site of resistance. In the second part of this essay, I argue that this thesis is complicated by the recently published Confessions of the Flesh, and its lengthy discussion of early-Christian virginity. I conclude by commenting on the historiographical limits to recuperate moments of resistance. (shrink)

Resistance and Rights. Comparing Arendt, Foucault, and YoungThe question if rights can be used in addressing gender-based oppression is at the center of recent debates in feminist theory. On the one hand, post-structuralist critiques have argued that differentiated rights, aimed at redressing injustices, reify the identity of oppressed groups (). On the other hand, proponents of differentiated rights have argued that these should be understood social-phenomenologically, as enabling social agents to counteract their oppression (Young 2011; ). This paper argues in (...) favor for the latter position while taking seriously the concern with regard to social identity articulated by the former. I do so by comparing Hannah Arendt and Michel Foucault on the relation between resistance and rights. Starting from the observation that Arendt and Foucault agree on the need for a new law that can curtail the destructive dynamics of late-modernity, I argue that their account of resistance ascribes great importance to rights. Discussing the two authors in turn, I focus on two parallel themes. Firstly, confronted with the fight against anti-Semitic persecution (Arendt) and the struggle against governmental techniques (Foucault), they invoke rights against the near-total domination by late-modern states. Secondly, reflecting on how freedom practices require relationships with others in which one can develop one’s individual uniqueness, they hint towards rights that consolidate these relationships, of which friendship is the paradigmatic example. In conclusion, I return to the feminist debate on differential rights to show how Young’s model of communicative democracy is influenced by and is an instance of the relational rights that can be found in Arendt and Foucault.

Biesta distinguishes three functions of education: qualification, socialization and subjectification. We focus on subjectification. When first addressing this concept, Biesta referred to action as defined by Arendt, thereby stressing the importance of ‘the question of freedom’. More recently, the question of freedom is replaced by ‘the question of responsibility’. For Levinas responsibility is related to irreplaceability. While the concept of responsibility is valuable, we question the call upon irreplaceability in education. Actively taking responsibility where irreplaceability might not be either present (...) or felt should be central to education. Unlike the morally clear examples invoked by Biesta, complex societal issues like the climate and refugee crisis are not accessible as an immediate appeal to a specific subject. Therefore, we propose a return to Arendt and her concept of action. Action allows and requires students to create the world anew, to take a position without pretending that the outcome can be controlled. Biesta refers to this as the impossibility of education. However, rather than repeating the theme of impossibility, we focus on the possibilities of education: there are several ways to create the world anew. (shrink)

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)

La présente contribution propose une étude de la périphérie gauche au sein d’un corpus oral multigenres, représentant douze activités de communication orale, annoté syntaxiquement et prosodiquement. La segmentation discursive du corpus en unités de base du discours (BDU) résulte d’une coïncidence entre unités syntaxiques et prosodiques, correspondant à des encodages linguistiques distincts mais complémentaires. Partant du postulat selon lequel ces unités discursives remplissent une fonction cognitive dans la planification et l’interprétation du discours, nous nous intéressons à l’étude de leur périphérie (...) gauche. Ce lieu, qui constitue le point d’ancrage du message, joue en effet un rôle important dans la négociation de la structure discursive. Dans l’objectif d’étudier les stratégies discursives à l’œuvre dans les différents genres du corpus, nous faisons l’inventaire des types formels observés et étudions finalement les fonctions discursives que ces éléments périphériques peuvent revêtir.

A key argument of Dixon et al. in the target article is that prejudice reduction through intergroup contact and collective action work in opposite ways. We argue for a complementary approach focusing on extreme emotions to understand why people turn to non-normative collective action and to understand when and under what conditions extreme emotions may influence positive effects of contact on reconciliation.

This chapter introduces the topics investigated in this book and it frames them in a broader historical and philosophical analysis of programming and computing technology.

This book presents a systematic philosophical and historical analysis of operating systems (0S). The discussion starts with the evolution of OSs since before their birth. It continues with a comprehensive philosophical analysis grounded in technical aspects. Coverage looks at software and (where appropriate) hardware as well as their historical developments. The authors not only offer historical and philosophical reflections on operating systems. They also explore the programs they coordinate and trace the epsitemic and ontological consequences of their designs. Each chapter (...) investigates one or more overlapping fragments of this fascinating history. These include: the birth of the UNIX system and the development of early systems and prototypes; a conceptual analysis of the plurality of systems; an investigation into business, ethical, and aesthetics aspects related to operating systems; and logical principles of formal languages. This book will interest researchers from a diversity of backgrounds. It will appeal to historians, philosophers, as well as logicians and computer scientists who want to engage with topics relevant to the history and philosophy of programming and more specifically that of operating systems.

BackgroundPatient-centeredness, respect for patient autonomy, and shared decision-making have now made it to center stage in discussions on quality of care. Knowing what actually counts in care and how it should be accomplished from the patients’ and nurses’ perspective seems crucial.AimTo explore how patients and their nurses perceive the importance and enactment of values in their healthcare.Research designAn observational, cross-sectional study using a self-developed questionnaire, consisting of 15 items related to seven values (e.g. uniqueness, autonomy, professionalism, compassion, responsiveness, partnership, and (...) empowerment) as described in the taxonomy of Bastemeijer et al.Participants and research contextThe survey was completed by 384 patients and 81 nurses. Participants were recruited on eight internal medicine wards of a 1000-bed university hospital in Belgium.Ethical considerationsThis study was approved by the ethical committee of the Ghent University Hospital (B670201836799).Findings(1) Patients and nurses prioritize values of care differently; (2) nurses report not being able to enact the values they prioritize in actual practice as much as one would like to; and (3) there is a gap in experienced delivery of a comprehensible explanation of all treatment options, a conversation based on equality, making shared decisions, and being non-judgmental between nurses and patients.DiscussionOur findings challenge nurses’ overemphasis on professional compassion and uniqueness while arguing for increased attention on authentic shared decision-making and empowerment. The first step to a patient-centered culture truly involving patients in their healthcare is communication and information provision, rather than focusing on tangible and normative constructs.ConclusionOur findings revealed differences in prioritization and actual enactment of values in care between patients and nurses. This was especially so for values related to communication, provision of complete unbiased information, and shared decision-making. Nurses should prioritize providing comprehensible information and using conversations based on equality to make decision together with patients. (shrink)

To discuss moral behavior in organizations, a growing number of authors turn to a ‘virtue ethics’ approach. Central to this approach is the so-called moral character of individuals in organizations: a well-developed moral character enables organizational members to deal with the specific moral issues they encounter during their work. If a virtue ethics perspective is seen as relevant, one may ask how organizations can facilitate that their members can exercise and develop their moral character. In this paper, we argue that (...) the way tasks are defined and interlinked has a profound influence on “exercising and developing moral character”—it can enhance and frustrate it. In order to show how structures may support organizational members to exercise and develop their moral virtues, the paper first describes what it means to exercise and develop virtues in an organizational setting and what is required for it. Next, the paper sets out to explain how specific values on different structural parameters at different structural levels relate to exercising virtues in organizations. (shrink)

What is the significance of high-speed computation for the sciences? How far does it result in a practice of simulation which affects the sciences on a very basic level? To offer more historical context to these recurring questions, this paper revisits the roots of computer simulation in the development of the ENIAC computer and the Monte Carlo method. With the aim of identifying more clearly what really changed (or not) in the history of science in the 1940s and 1950s due (...) to the computer, I will emphasize the continuities with older practices and develop a two-fold argument. Firstly, one can find a diversity of practices around ENIAC which tends to be ignored if one focuses only on the ENIAC itself as the originator of Monte Carlo simulation. Following from this, I claim, secondly, that there was no simulation around ENIAC. Not only is the term ‘simulation’ not used within that context, but the analysis also shows how ‘simulation’ is an effect of three interrelated sets of different practices around the machine: (1) the mathematics which the ENIAC users employed and developed, (2) the programs, (3) the physicality of the machine. I conclude that, in the context discussed, the most important shifts in practice are about rethinking existing computational methods. This was done in view of adapting them to the high-speed and programmability of the new machine. Simulation then is but one facet of this process of adaptation, singled out by posterity to be viewed as its principal aspect. (shrink)

A history of writing the history of computing is presented in its relationship to the history of mathematics. As with many historiographies, the initial history of computing was very much an internalistic history. In the late 1970s, the field became more serious and started looking at the histories of mathematics and technology for (methodological) inspiration. Whereas the history of mathematics was initially quite influential, it is the history of technology (in its U.S. form) that has become the dominant framework for (...) doing history of computing since the 1990s.

In 1931 Kurt Gödel published his incompleteness results, and some years later Church and Turing showed that the decision problem for certain systems of symbolic logic has a negative solution. However, already in 1921 the young logician Emil Post worked on similar problems which resulted in what he called an “anticipation” of these results. For several reasons though he did not submit these results to a journal until 1941. This failure ‘to be the first’, did not discourage him: his contributions (...) to mathematical logic and its foundations should not be underestimated. It is the purpose of this article to show that an interest in the early work of Emil Post should be motivated not only by this historical fact, but also by the fact that Post’s approach and method differs substantially from those offered by Gödel, Turing and Church. In this paper it will be shown how this method evolved in his early work and how it finally led him to his results. (shrink)
