For each vertex of a simple polygon P an integer valued weight is given. We consider the path p1, p2, ..., pk in P which is created according to the following strategy: p1 is a designated start vertex s and pi+1 is obtained by choosing the vertex with smallest weight among all vertices visible from pi and different from p1, p2, ..., pi. If there is no such vertex the path is finished. This path is called geometric lexicographic dead end (...) path. We shall prove the problem of determining whether a distinguished vertex t of P is on the geometric lexicographic dead end path or not to be P-complete. (shrink)

We consider the problem of quadrilaterizing an orthogonal polygon P, that is to decompose P into nonoverlapping convex quadrangles without adding new vertices. In this paper we present a CREW-algorithm for this problem which runs in O time using Θ processors if the rectangle decomposition of P is given, and Θ processors if not. Furthermore we will show that the latter result is optimal if the polygon is allowed to contain holes.

This article examines a frequent assumption of sociological accounts of knowledge: the idea that knowledge acts. The performativity of knowledge claims is here analysed through the prism of ‘sociological excuses’: the idea that sociological explanations can act as ‘excuses’ for otherwise unacceptable behaviour. The article builds on Austin’s distinction between illocutionary and perlocutionary effects to discuss the relationship between sociological explanation, sociological justification and sociological critique. It argues that understanding how (and if) sociological explanations can act requires paying attention to (...) social and political conditions of performativity and their transformation in late liberalism.

This paper explores the problem of racial privilege in US American feminist thought. Drawing on Gayatri Spivak’s analysis of ethics, particularly her ideas of epistemic discontinuity and teleopoietic reading, I argue that a specific kind of ethical openness can help feminist social-political philosophy better negotiate the legacy of white privilege. Spivak’s work calls for a reconsideration and reworking of the subject who theorizes. Her analysis of ethics suggests that racially privileged feminists must be able to confront their own complicity in (...) order to engage in political critique less likely to recreate historical patterns of racial domination and exclusion.

Critics of Aristotelian accounts of practical reasoning, in teaching and in other contexts, criticise phronesis for its rigidity and lack of imagination. This paper argues that phantasia, or imagination, helps us to develop a richer account of Aristotle’s phronesis. Two senses of phantasia, as producing images and as an interpretive faculty, are proposed here to be importantly involved in phronesis. By producing images that help in the selection of an end goal, and by having an interpretive faculty that helps to (...) compare competing possibilities, phantasia plays a crucial role in the practical reasoning process of phronesis.

This paper presents a proposal for the description of gesture phases derived from articulatory characteristics observable in their execution. Based on the results of an explorative study examining the execution of gesture phases of ten German speakers, the paper presents two sets of articulatory features, i.e., distinctive and additional features by which gesture phases are characterized from a context-independent and context-sensitive point of view. It will be shown that gesture phases show a particular distribution of the features, thus distinguishing one (...) phase from another. Furthermore, changes in the execution of phases in linear successions can be described by means of features. Contrary to other accounts, whose focus on gesture phases is primarily in relation to speech and/or adjacent phases, this proposal concentrates on the visible physical characteristics of gesture phases.

This study investigated Belgian and Dutch parental opinions on confidentiality and consent regarding medical decisions about adolescents. Through an online survey, we presented six cases (three on confidentiality, and three on consent) to 1,382 Belgian and Dutch parents. We studied patterns in parental confidentiality and consent preferences across and between cases through binomial logistic regressions and latent class analysis. Participants often grant the right to consent for a treatment to the adolescent, but the majority diverges from the adolescent’s preferences regarding (...) confidentiality. More educated participants would rather not be informed about cases regarding a sexually transmitted disease or depression than lower educated participants. Further analysis shows that participants’ preferences correspond to authoritative (47%), permissive (30%) and authoritarian (17%) parenting styles. Belgian and Dutch parents are willing to grant some degree of autonomy, but they want to be informed about specific health issues. Parental views on confidentiality and granting consent appear to mirror existing parenting styles. (shrink)

The concept of dramatization represents a rhetorical and conceptual tension in Deleuze's philosophy in that it refers both to autopoietic ontological processes and to a critical philosophical method. Commentators are wont to refer to either one or the other, saying little about how or if these two fundamentally distinct usages can be thought together; that is what we aim to do here. By unravelling the conceptual transformations of the term, we can gain an appreciation for the double characterisation of dramatization (...) and its centrifugal nature. We begin with the hypothesis that dramatization is linked to actualisation in the first sense and counteractualisation in the second. The fundamental question that we would like to address is: how are these two views to be reconciled? Addressing this question leads us to the conclusion that dramatization becomes an ethical imperative for philosophical subjects to perform certain philosophical exercises, that is, to become worthy of the event. The particular philosophical exercise that is emphasised is the dramatization of a paradoxical thought of death. Ultimately, we suggest that dramatization can be galvanised for both an emancipatory politics and an ethico-aesthetic life practice. (shrink)

Conversational artificial intelligence (CAI) presents many opportunities in the psychotherapeutic landscape—such as therapeutic support for people with mental health problems and without access to care. The adoption of CAI poses many risks that need in-depth ethical scrutiny. The objective of this paper is to complement current research on the ethics of AI for mental health by proposing a holistic, ethical, and epistemic analysis of CAI adoption. First, we focus on the question of whether CAI is rather a tool or an (...) agent. This question serves as a framework for the subsequent ethical analysis of CAI focusing on topics of (self-) knowledge, (self-)understanding, and relationships. Second, we propose further conceptual and ethical analysis regarding human-AI interaction and argue that CAI cannot be considered as an equal partner in a conversation as is the case with a human therapist. Instead, CAI’s role in a conversation should be restricted to specific functions. (shrink)

This article critically reflects on some of the themes and assumptions at stake in the “transracialism” controversy, and connects them to important works in critical race theory: namely Rey Chow's notion of “coercive mimeticism” and Sara Ahmed's critique of white liberal multiculturalism. It argues that the analytic account of “race” that Tuvel draws upon in her article—Sally Haslanger's—is politically problematic, both on its own terms and in light of broader reflections on racialized and gendered power relations. In particular, I critique (...) Haslanger's assumption that all racial identities exist on the same conceptual plane: that a single variable definition of “race” can be applied to any particular racialized group—including white and nonwhite racial identities. This erases racialized power relations, especially where, in liberal “multicultural” nations, whiteness constitutes the implied standard against which an appearance of “racial difference” is conjured. Finally, I extend my argument to the issue of treating “race” and gender analogously. Rejecting this move, I propose an alternative way of conceptualizing these as analytically distinct, yet constitutively interdependent, phenomena. In order to situate the debate historically, I consider an example of “racial transgression” from twentieth‐century China. (shrink)

This paper engages television comedy to critique the ethical values that are amenable to neoliberal capitalism. First, I explore the co-optation and containment of feminism as a collective social change movement by postfeminist and neoliberal cultures. I show how self-reliance and resilience become legible as classed, raced, and gendered values packaged for feminine, neoliberal women. Next, I address the specific challenges that neoliberal biopower poses for ethical values as they have been traditionally understood. I then argue that comedy is a (...) particularly effective medium through which to consider the generation of resistant values that can support feminist collectivity. I develop a provisional protocol for engaging ambivalent media and read two scenes from TV comedies focused on the femininity of class-aspiring or class-privileged women. This critically exposes what kinds of values might counter the co-optation of self-reliance and resilience. I conclude that cultural performances of femininity not only codify neoliberal values, they also are a resource for generating resistant feminist values inasmuch as they present intentionally frivolous modes of living. Within such a culture frivolousness becomes viable as a mode of everyday ethical commitment that can disrupt the negative impact of neoliberal biopower. (shrink)

In his commentary on Plato’s Parmenides Proclos describes the maternal and paternal contributions to reproduction as of equal value: The paternal seed furnishes potential λόγοι, the mother actualises them and so causes the reversion of the offspring. However, the definition of the mother as actualising cause is linked to the particular circumstances of conception in the sphere of nature. In general, Proclus bases his concept of femininity on the idea of a shared, but not equal activity by paternal and maternal (...) causes. In the metaphysical sphere the maternal cause is distinguished by its inspiring activity, that is, it provokes the procession of powers that are permanently anchored in the father and so it enables the begetting of the offspring as an entity separate from the father. This activity involves a loss of perfection, which is the basis for a difference in value between the activities of the maternal and paternal causes. (shrink)

We calculate the universal Euler characteristic and universal dimension function on semilinear and semibounded sets and obtain some criteria for definable equivalence of semilinear and semibounded sets in terms of these invariants.

Transformation in food systems poses new opportunities for improving environmental sustainability and reducing the use of farmed animals. Discussions about transforming current food systems have been centered mostly on replacing animal source proteins with plant-based alternatives and about how to minimize food waste and loss. Products from cellular agriculture are part of a novel food transition and are presented as new, sustainable alternatives for animal source proteins. However, justice and equity narratives in food system transition discussions concerning cellular agriculture are (...) rare. The aim of this study is to address how cellular agriculture may contribute to a just food system transition and to evaluate the prospects of such foods on this planet by reviewing narratives of cellular agriculture in 36 scientific articles. The data were analyzed using a justice transition framework. The results show that cellular agriculture has a potential to contribute to improving environmental sustainability if developers take justice into account as an important factor. Concerns are that cellular agriculture has the potential to be an exclusive food and may introduce regional variances exacerbating inequalities within the food system. We contribute to the discussion of just food system transitions by highlighting the importance of justice considerations in the context of cellular agriculture. Key aspects include the need for fair distribution along the value chain, global access to cellular agriculture benefits, and the recognition of social transformations in technological solutions. Additionally, transparent decision-making, open data access, and capacity building for stakeholders emerge as critical elements for fostering equitable and sustainable development in cellular agriculture.

Let R be an o-minimal field with a proper convex subring V. We axiomatize the class of all structures such that , the corresponding residue field with structure induced from R via the residue map, is o-minimal. More precisely, in Maříková [8] it was shown that certain first-order conditions on are sufficient for the o-minimality of . Here we prove that these conditions are also necessary.

This paper attempts to give a survey of the origin of the present collection of some forty works of Grotius in the present Scientific Library of Olomouc. After a short introduction about education in the Czech lands and especially in Olomouc, the present works of Grotius are discussed in connection with their origin. Most works were added to the collection due to the Josephine abolition of monasteries in the 1780s. Premonstratensian and Cistercian monasteries were the most important former possessors. A (...) couple of Grotiana were donated by noblemen. A look is given to some course books that have been preserved. A complete list of all works of Grotius printed before 1800, present in the Scientific Library with an identification of their owners, is given in the annex. (shrink)

Tento článek se zabývá dvěma aritmetickými systémy - konkrétně systémem, který představil R. Dedekind a systémem, který vytvořil G. Frege - a paradoxy, které se zde vyskytují - tedy Burali-Fortiho paradoxem (což je vůbec první fomrulace moderního paradoxu), Cantorovým paradoxem a Russellovým paradoxem. Hlavním cílem je ukázat, co mají tyto paradoxy společného a zdůvodnit, že ačkoli se tyto paradoxy vyskytují v různých systémech, mají společné znaky. Na základě studia uvedených systémů, paradoxů i různých řešení těchto paradoxů, autorka dospívá k tvrzení, (...) že zkoumané paradoxy vznikají na stejném základě, a to na základě problému nehierarchizovanosti.V dodatku tohoto článku navíc čtenář nalezne dva zajímavé historické exkurzy. První z nich předkládá v historicky autentické podobě odvození Burali-Fortiho paradoxu Druhý exkurz je věnován Russellovu paradoxu a představuje jej nejen v podobě, jak jej vyjádřil B. Russell, ale také ve formulaci G. Frega. (shrink)

This book offers a thorough technical elaboration and philosophical defense of an objectivist informational interpretation of quantum mechanics according to which its novel content is located in its kinematical framework, that is, in how the theory describes systems independently of the specifics of their dynamics. -/- It will be of interest to researchers and students in the philosophy of physics and in theoretical physics with an interest in the foundations of quantum mechanics. Additionally, parts of the book may be used (...) as the basis for courses introducing non-physics majors to quantum mechanics, or for self-study by those outside of the university with an interest in quantum mechanics.

This essay facilitates a critical dialogue between Freud’s early “cathartic method” and Fanon’s notion of a “neurotic situation.” Although Fanon does not explicitly develop this concept as a counterpoint to the Freudian understanding of neurosis, we can nevertheless glean from his work a robust understanding of the kind of psycho-political suffering it designates. To be in a “neurotic situation,” I argue, is to experience neurotic symptoms that are idiosyncratic to oneself and yet also a reflection of social and political structures (...) of oppression that affect all members of an oppressed group. It is a situation that contains both idiosyncratic psychic disturbance and non-idiosyncratic political truth. As such, addressing a neurotic situation requires overcoming the strict separation between therapy and consciousness-raising that some activists espouse. Specifically, in a neurotic situation, therapy and emancipatory consciousness-raising come to shape and condition each other’s objectives: an emancipatory consciousness becomes a condition for the therapeutic alleviation of neurotic symptoms, and therapeutic relief for neurotic symptoms becomes part of what it is like to attain an emancipatory consciousness in a neurotic situation.

Although much has been written about the nature of philosophy and how the discipline can be defined, little attention has been paid to the ways we develop the facility to reflect philosophically or why cultivating this ability is valuable. This article develops a conception of “philosophical sensitivity,” a perceptual capacity that facilitates our awareness of the philosophical dimension of experience. Based in part on Aristotle's notion of a moral perceptual capacity, philosophical sensitivity starts with most people's natural inclinations as children (...) to reflect about life's fundamental mysteries; when this capacity is cultivated with training over time, our attentiveness to the philosophical features of ordinary life becomes almost second nature. In much the same way an aesthetically sensitive person notices certain qualities of experience not readily perceptible by others, philosophical sensitivity involves the development of a particular way of seeing the world.

This article introduces the concept of epistemic positioning to theorize the relationship between identity-based epistemic judgements and the reproduction of social inequalities, including those of gender and ethnicity/race, in the academia. Acts of epistemic positioning entail the evaluation of knowledge claims based on the speaker’s stated or inferred identity. These judgements serve to limit the scope of the knowledge claim, making it more likely speakers will be denied recognition or credit. The four types of epistemic positioning – bounding (reducing a (...) knowledge claim to elements of personal identity), domaining (reducing a knowledge claim to discipline or field associated with identity), non-attribution (using the claim without recognizing the author) and appropriation (presenting the claim as one’s own) – are mutually reinforcing. Given the growing importance of visibility and recognition in the context of increasing competition and insecurity in academic employment, these practices play a role in the ability of underrepresented groups to remain in the academic profession.

Critical accounts over the past years have focused on neoliberalism as a subject of knowledge; there has been a recently growing interest in neoliberalism as an object of knowledge. This article considers the theoretical, epistemological and political implications of the relationship between neoliberalism as an epistemic subject and neoliberalism as an epistemic object. It argues that the ‘gnossification’ of neoliberalism – framing it an epistemic project, and deriving implications for political engagement from this – avoids engaging with numerous ambiguous elements (...) of the production of knowledge. Drawing on Bourdieu’s concept of the ‘scholastic fallacy’ and Boltanski and Chiapello’s work in sociology of critique, the article lays out a framework for the study of the relationship between epistemic, moral, and political elements of critique of neoliberalism, including the conditions of its own production in contemporary academic contexts.

In this article, I focus on Alain Badiou’s idiosyncratic interpretation of Jacques Lacan and highlight his conceptual points of divergence with the psychoanalyst. I elaborate on Badiou’s distinction between philosophy, antiphilosophy, and sophistry as well as the notions of sense, ab-sense, and non-sense that he proposed in the book There’s No Such Thing as a Sexual Relationship: Two Lessons on Lacan as well as in his seminar on Lacan. Unlike Lacan, who affirmed that philosophy is subject to the fantasy of (...) the One, Badiou claimed that the One exists merely as a result of an operation of counting. In this manner, he contested Lacan’s conviction that philosophy forecloses the real. I argue that Badiou’s main point of divergence with Lacan is centred on the notion of the subject and on the localization of the void in relation to the subject. I also touch upon philosophy’s relation to the symbolic, namely its ability to raise powerlessness to logical impossibility. (shrink)

Alias Grace is just one of the many recent TV shows that was labelled ‘feminist’ so quickly and with such ease that one is left to wonder how much of a genre ‘feminism’ has already become. This article interrogates what is at stake for ‘feminist’ critique in labelling cultural phenomena as ‘feminist’. I argue that certain ways of reading Alias Grace as a ‘feminist’ show preclude an alternative reading in which Alias Grace emerges as a critique of ‘feminism’ itself. What (...) is at stake in the debate on ‘feminism’ in popular culture is thus not only whether or not we can recognise the potential for ‘feminist’ critique that resides within popular culture, but also whether or not we can allow socio-cultural phenomena, like TV shows, to take ‘feminism’ as an object of critique: to generate the kind of critical movement that renders futile any attempt to stabilise, or reify, the signifier ‘feminism’ as an ahistorical object with fixed meanings – as a genre even. In so doing, I take it that there is no privileged site from which to engender such movement; and I do not take popular culture as a self-contained domain that could qualify for being such a site. The point, then, is not to treat Alias Grace as a representative case study in popular ‘feminism’; but rather, to demonstrate, by way of Alias Grace, the complex and contradictory readings that socio-cultural phenomena are amenable to, and which in turn give rise to critical possibilities that unfold from within these phenomena. Reading Alias Grace critically, as I understand it in this article, means allowing it to be, at one and the same time, a reflection on itself and a reflection on the world in which it so quickly comes to be labelled ‘feminist’.

We examine the embodiment of one foundational aspect of human cognition, language, through its bodily association with the gestures that accompany its expression in speech. Gesture is a universal feature of human communication. Gestures are produced by all speakers in every culture . They are tightly timed with speech . Gestures convey important communicative information to the listener, but even blind speakers gesture while talking to blind listeners , so the mutual co-occurrence of speech and gesture reflects a deep association (...) between the two modes that transcends the intentions of the speaker to communicate. Indeed, we believe that this linkage of the vocal expression of language and the arm movements produced with it are a manifestation of the embodiment of thought: that human mental activities arise through bodily interactions with the world and remain linked with them throughout the lifespan. In particular, we propose that speech and gesture have their developmental origins in early hand-mouth linkages, such that as oral activities become gradually used for meaningful speech, these linkages are maintained and strengthened. Both hand and mouth are tightly coupled in the mutual cognitive activity of language. In short, it is the initial sensorimotor linkages of these systems that form the bases for their later cognitive interdependence. (shrink)

Understanding Chinese philosophy requires knowledge of the referential framework prevailing in Chinese intellectual traditions. But Chinese philosophical texts are frequently approached through the lens of Western paradigms. Analysing the most common misconceptions surrounding Western Sinology, Jana Rošker alerts us to unseen dangers and introduces us to a new more effective way of reading Chinese philosophy. Acknowledging that different cultures produce different reference points, Rošker explains what happens we use rational analysis, a major feature of the European intellectual tradition, to (...) read Chinese philosophy. We rely on impossible comparisons, arrive at prejudiced assumptions and fail to arrive at the truth, the consequence of applying a different methodology to the process of perceiving, understanding and interpreting reality. Instead of transferring concepts and categories from Western sinology onto socio-cultural Chinese contexts, Rošker constructs a new methodology of reading, understanding and interpreting Chinese philosophy. She opens our eyes to the basic problems of Western paradigms, encourages intercultural approaches and allows us to master a more autochthonous understanding of Chinese philosophy. (shrink)
