In this paper, we study some new examples of ideals on $$\omega $$ with maximal Tukey type (that is, maximal among partial orders of size continuum). This discussion segues into an examination of a refinement of the Tukey order—known as the weak Rudin–Keisler order—and its structure when restricted to these ideals of maximal Tukey type. Mirroring a result of Fremlin (Note Mat 11:177–214, 1991) on the Tukey order, we also show that there is an analytic P-ideal above all other analytic (...) P-ideals in the weak Rudin–Keisler order.

In an earlier paper, we introduced the following pre-order on the subgroups of a given Polish group: if G is a Polish group and \ are subgroups, we say H is homomorphism reducible to L iff there is a continuous group homomorphism \ such that \\). We previously showed that there is a \ subgroup L of the countable power of any locally compact Polish group G such that every \ subgroup of \ is homomorphism reducible to L. In the (...) present work, we show that this fails in the countable power of the group of increasing homeomorphisms of the unit interval. (shrink)

Given a class${\cal C}$of subgroups of a topological groupG, we say that a subgroup$H \in {\cal C}$is auniversal${\cal C}$subgroupofGif every subgroup$K \in {\cal C}$is a continuous homomorphic preimage ofH. Such subgroups may be regarded as complete members of${\cal C}$with respect to a natural preorder on the set of subgroups ofG. We show that for any locally compact Polish groupG, the countable powerGωhas a universalKσsubgroup and a universal compactly generated subgroup. We prove a weaker version of this in the nonlocally compact (...) case and provide an example showing that this result cannot readily be improved. Additionally, we show that many standard Banach spaces have universalKσand compactly generated subgroups. As an aside, we explore the relationship between the classes ofKσand compactly generated subgroups and give conditions under which the two coincide. (shrink)

We consider some natural sets of real numbers arising in ergodic theory and show that they are, respectively, complete in the classes${\cal D}_2 \left( {{\bf{\Pi }}_3^0 } \right)$and${\cal D}_\omega \left( {{\bf{\Pi }}_3^0 } \right)$, that is, the class of sets which are 2-differences (respectively,ω-differences) of${\bf{\Pi }}_3^0 $sets.

The present work determines the arithmetic complexity of the index sets of u.c.e. families which are learnable according to various criteria of algorithmic learning. Specifically, we prove that the index set of codes for families that are TxtFex\-learnable is \-complete and that the index set of TxtFex\-learnable and the index set of TxtFext\-learnable families are both \-complete.

The concept of “predatory” publishing, despite many studies of the phenomenon, continues to be unclear. This paper visualizes this topic through an epistemological perspective, claiming that these limitations emerge from an impressionism of idealization, the entrapment of cause and effect induced by a journalology-based perspective, and entrenched fantasized extraction, imagination and divination of what constitutes the truth, in essence, a path never followed by an _epistēmōn_. Reality, proof, verification, recorded observations and their interpretations have been pivoted to fit the theoretical (...) flavor of the day, an entity one day being predatory, the next not. Perhaps ephemeral judgements of predatory have been built on boundless disregard for common sense. Yet, these have led to scientists’ apotheosis, almost oblivious of the intangibility of “valid”, or the infinitesimal continuum of “predatory”. Perhaps their fault-ridden authoritarian argumentative disabilities is at fault. (shrink)

Although the Chronicle of Theodore of Kyzikos has been known to scholarship and was included in Kurmbacher's Geschichte Der Byzantinischen Litteratur, it was later identified with the Synopsis Chronike, and hence excluded from any further research. The article reconsiders the text and its place in Byzantine historiography, focusing on its relationship to the Synopsis Chronike. It analyses their similarities and differences, particularly in terms of textual criticism, and examines possible connections between them. Finally, it concludes that the accepted hypothesis that (...) the two texts are one and the same (or mere variations of the same text) is not valid. Instead, it proposes that the Chronicle of Theodore of Kyzikos and the Synopsis Chronike are two distinct chronicles that derive from an earlier common archetype, which is now lost. (shrink)

The main purpose of this study was to examine the relationship between flow experience and goal orientation theory, as well as, the differences in flow experience based on the orthogonal model of goal orientation theory. Two hundred and seventy eight athletes completed the Task and Ego Orientation Sport Questionnaire based on how they usually feel. The Flow State Scale was completed thirty minutes after an important competition, along with the challenge-skill ratings, based on how athletes felt during the particular competition. (...) The results indicated that the athletes’ task orientation may be the critical factor for attaining flow in competitive sport, feeling more skillful and estimating the upcoming competition as challenging, while ego orientated athletes lack these elements, which are important for them to get into flow. Additionally, the balance between athletes’ goal orientation preferences seems important for the formation of flow experience. (shrink)

Responsible research and innovation (RRI) is a governance framework promoted by influential policy makers such as the European Commission and academics from the fields of science and technology studies and management. This book is the first text to serve industry. Inspired by existing Corporate Responsibility standards and principles, it offers a selection of tools that can assist practitioners in implementing RRI in business and industry. -/- Responsible Research and Innovation (RRI) is integrative. It is a convergence of Technology Assessment (TA) (...) and Ethics, including corporate responsibility. The task of linking RRI to existing frameworks has only just begun. This book is a welcome example, showing how Corporate Responsibility tools can drive the implementation of RRI. Prof. Armin Grunwald, Head of the Office of Technology Assessment at the German Bundestag and Head of the Institute for Technology Assessment and Systems Analysis, Karlsruhe Institute of Technology, Germany. -/- This is a simple, short, yet encyclopaedic work designed to help business implement RRI using the many tools of Corporate Responsibility (CR) already in place, everything from ISO9001 to the Ceres Roadmap for Sustainability. It makes clear the ways in which RRI is an extension of ideas already well-developed in CR. I learned a lot reading it.

Over every and each sport event, a dark veil spreads and obfuscates the celebration: doping. Although anti-doping policies have been widely applied, controlling and diminishing this phenomenon has not been achieved yet and the use of doping is commonplace. In this article, I propose the concept of narcissistic civilization as a tool to interpret this phenomenon. I seek for a parallel reading between the Freudian idea of narcissism and its extension to social narcissism by Fromm, together with Heidegger’s analysis of (...) technology, keeping in mind that doping is a technological application. In this way I point out that both theories share a common view in that humans tend to fail in the distinction between the external reality as an object and their own self as the interpreter, that is between the ¨I¨ and the ¨not I¨. By making this fusion of the two theories that originate from different intellectual traditions, I aspire to provide an interpretation tool for the broad use of doping: I conclude that doping can be understood with the assumption of a narcissistic civilization, focused on technology, that calls for the use of PEDs.

This paper analyses the role of external pressures, internal motivations and their interplay, with the intention of identifying whether they drive substantive or instead symbolic implementation of ISO 14001. The context is one of economic crisis. We focus on Greece, where the economic crisis has weakened the country’s institutional environment, and analyse qualitatively new interview data from 45 ISO 14001 certified firms. Our findings show that weak external pressures can lead to a symbolic implementation of ISO 14001, as firms can (...) defend their legitimacy without incurring the costs of internalization in the local market; weak external pressures can lead to substantive implementation of ISO 14001 when firms have strong internal motivations seeking to strategically differentiate from competitors in international markets. Firms internalize ISO 14001 so as to restore their legitimacy and reputation in foreign markets and stimulate their competitiveness; and strong internal motivations pave the way for companies to stimulate their competitiveness by enhancing their efficiency, as some companies might strengthen their position in the local market by implementing ISO 14001 substantively. The contribution of this paper to the literature on ISO 14001 internalization lies in refining existing theory on the importance of internal motivations for the substantive implementation of ISO 14001 in the context of economic crisis. In addition, this paper extends current theory by challenging studies that dismiss the importance of external pressures. We argue that the intensity of external pressures influences the internalization of ISO 14001, but propose that this relationship might not be linear. (shrink)

Misgendering is perceived as the use of incorrect pronouns and gender categories when addressing Transgender and Gender Non-Conforming people. This common habit is widely observed in reports, surveys and assessments, where the pressures to comply with a binary understanding of gender are high and alternative options for self-identification are not frequently offered. The present study reads misgendering as a manifestation of epistemic injustice, and uses resources from Science, Technology and Society Studies in order to highlight the importance of situated perspectives (...) on the matter. After being analysed as a commonplace microaggression, misgendering is conceptualised as an act of structural hermeneutical marginalisation that is not usually intentional but product of society’s lack of sensibility towards gender diversity. Finally, a reparative approach against misgendering is offered through the Gender Fair Language model, which involves relational and situated contributions in order to prevent already marginalised people and experiences from being further excluded.

In this paper, we analyse higher-order risky choices by the representative cumulative prospect theory (CPT) decision maker from three alternative reference points. These are the status quo, average payout and maxmin. The choice tasks we consider in our analysis include binary risks, and are the ones employed in the experimental literature on higher order risk preferences. We demonstrate that the choices made by the representative subject depend on the reference point. If the reference point is the status quo and the (...) lottery choices exhibit symmetric risk, we demonstrate that there is no third order reflection effect of lottery choices but there is a fourth order reflection effect. When the average payout is the reference point, we demonstrate that any third or fourth order lottery choice is possible dependent upon the lottery payoffs. However, under the assumption of maxmin reference point, the risky choices are prudent and temperate. In addition to these results, our analysis reveals that the representative CPT subject can choose combinations of second with third and fourth order risky options that differ from those in other major models of decision under risk. We contrast our theoretical predictions with the empirical results reported in the literature on higher order risk preferences and are able to reconcile some conflicting experimental evidence.

We show that Gabbay’s nonmonotonic consequence relations c an be reduced to a new family of relations, called entrenchment relations. Entrenchment relations provide a direct generalization of epistemic entrenchment and expectation ordering introduced by G ̈ardenfors and Makinson for the study of belief revision and expectation inference, respectively.

We argue that cognitive models can provide a common ground between human users and deep reinforcement learning (Deep RL) algorithms for purposes of explainable artificial intelligence (AI). Casting both the human and learner as cognitive models provides common mechanisms to compare and understand their underlying decision-making processes. This common grounding allows us to identify divergences and explain the learner's behavior in human understandable terms. We present novel salience techniques that highlight the most relevant features in each model's decision-making, as well (...) as examples of this technique in common training environments such as Starcraft II and an OpenAI gridworld.

A central concept for information retrieval is that of similarity. Although an information retrieval system is expected to return a set of documents most relevant to the query word(s), it is often described as returning a set of documents most similar to the query. The authors argue that in order to reason with similarity we need to model the concept of discriminating power. They offer a simple topological notion called resolution space that provides a rich mathematical framework for reasoning with (...) limited discriminating power, avoiding the vagueness paradox.

Terpsicles is neglected in all current Histories of Greek Literature and Dictionaries of Antiquity, except for a five-lines-long entry by E. Bux in Real-Encyclopädie V.A. 790. He is the author of a treatise Περί ἀΦροδισίων, which is only known from two references in Athenaeus—7.325d and 9.391e—and seems to have been a collection of sex-related marvels. In the first passage he provides a piece of information on the red mullet.

Plato was a Socrates’ friend and disciple, but he wasn’t the only one. No doubt, Socrates had many followers, however, the majority of their work is lost. Was there any antagonism among his followers? Who succeeded in interpreting Socrates? Who could be considered as his successor? Of course, we don’t know if these questions emerged after the death of Socrates, but the Greek doxography suggests that there was a literary rivalry. As we underlined earlier, most unfortunately, we can’t examine all (...) of them thoroughly due to the lack of their work, but we can scrutinize Xenophon’s and Aristippus’ work. All of them, Plato, Xenophon and Aristippus, presented to a certain extent their ideas concerning education. Furthermore, they have not neglected the matter of gymnastikè, but what is exactly the role of physical education in their work? Are there any similarities or any differences between them? Since, Xenophon and Aristippus (as well as Plato) seem to be in favor of gymnastikè, it is necessary to understand its role. (shrink)

The paper presents the main preliminary findings of GEITONIA research project (Growing and Enabling of Information Technologies for Online Neighborhoods: Implications and Applications). Focusing on the development of a local social network for neighborhoods of Nea Smyrni community in Attica (Greece), the main results of an exploratory mixed methods research study, are discussed. The local social network is a non-commercial social medium that operates as a mobile application. Residents of the local community will have the opportunity to use the application (...) for a pilot period, create their virtual neighborhoods, interact with other neighbors, and expand local social ties in a continuum of physical and virtual spatialities. Moreover, taking into consideration residents’ perceptions, demands and visions, regarding a local social network for their neighborhoods, the research project aims to enhance the rule that sets the focus on the users, as co-creators and co-producers of communication technologies.

This manuscript, divided into two parts, provides a contextual and historiographical analysis of Edwin Arthur Burtt's classic The Metaphysical Foundations of Modern Physical Science. My discussion corroborates the sparse technical literature on Burtt (Moriarty, 1994; Villemaire, 2002), positioning his work in the aftermath of American idealism and the rise of realist, pragmatist and naturalist alternatives. However, I depart from the existing interpretations both in content and focus. Disagreeing with Moriarty, I maintain that Burtt's Metaphysical Foundations is not an idealist work. (...) Moreover, I provide an alternative to Villemaire's mainly Deweyite/pragmatist reading, emphasizing the import of new realism and naturalism. Burtt's historical thesis should not be viewed as outlining a systematic philosophical position, but rather as a (coherent) culmination of numerous philosophical problematics. To support my conclusion, I provide a substantial summary of Burtt's text alongside a contextual analysis of the philosophical issues that preoccupied his teachers and peers in Columbia's philosophy department. I conclude with a historiographical section, rendering explicit the connections between Burtt's understanding of the scientific revolution, and his distinctive early 20th century American intellectual context.

This book offers the first systematic reading of Plato’s Laches in English after three decades of scholarly silence. It rekindles interest in this much-neglected dialogue by providing a fresh discussion of the major issues that arise from the text. Among these issues, pride of place is taken by the virtue of courage, for the definition of which Socrates is depicted as engaging in some long-winded dialectical exchange with his interlocutors. Yet, although there is no room for doubt that the Laches (...) is Plato’s most explicit treatment of courage, this dialogue ends in perplexity and is thus traditionally thought of as an unsuccessful attempt to define what courage is. The present study challenges this suggestion. This book proposes a new paradigm for the interpretation of Plato’s Laches. In fact, it constitutes the first systematic attempt to study the dialogue in light of the idea that its composition could well have formed part of Plato’s overall plan to establish a well-defined and rigorous justification of the life of philosophical inquiry The book will be of key interest to classicists, philosophers, and intellectual historians, but will also appeal to students or anyone interested in ancient Greek philosophy.

The covid-19 pandemic has supposed a greater marginalization of sexual and gender minorities. This marginalization has been an effect both of the public management’s prioritization of the epidemiological situation, and of a generalized social backlash attributed to the unprecedented lockdown conditions. Within this framework, and among other vulnerable social collectivities, trans people have seen their testimonies particularly unaddressed and exempt of credibility. Group dynamics of reinforcement of categories, as well as the dissemination of fake news through the Internet and the (...) reactivation of outdated debates on legitimacy within the public sphere, have given rise to a generalized mistrust and polarization. The present text utilizes qualitative data obtained through a larger research project on accessibility of trans people to psychological services, to conflate barriers to health services, with infodemia on social media, social distancing, the uprising of conservative discourses, and minority stress.

Research on bounded rationality has two cultures, which I call ‘idealistic’ and ‘pragmatic’. Technically, the cultures differ on whether they build models based on normative axioms or empirical facts, assume that people's goal is to optimize or to satisfice, do not or do model psychological processes, let parameters vary freely or fix them, aim at explanation or prediction and test models from one or both cultures. Each culture tells a story about people's rationality. The story of the idealistic culture is (...) frustrating, with people in principle being able to know what they should do, but in practice systematically failing to do it. This story makes one hide in books for intellectual solace or surrender to the designs of someone smarter. The story of the pragmatic culture is empowering: If people are educated to use the right tool in the right situation, they do well. (shrink)

This article foregrounds an unofficial, “dark” strand of shamanic revival, which lies at the interstices of local inspirational religion and the state’s law in a Siberian periphery. Focusing on consultations concerned with ritual healing and counter-cursing in the Russian Republic of Tuva/tyva, southern Siberia, the article documents a field of metaphysical disorder which is governed by shamans as purveyors of “forensic” evidence of cursing and as arbiters of justice. The data on counter-cursing consultations evince a social perception of shamanism as (...) a redress for kinds of violence which transcend the limits of state law. Drawing on two shamanic narratives of affliction and its professionalization as a charisma for healing and revenge respectively, the article argues that a new kind of “forensic” evidence of crime and violence emerges from the materials on counter-cursing in Kyzyl.

AbstractIn the wake of organizational scandals associated with corporate America servant as well as transformational leadership are seen as approaches capable of engendering a type of morality—on the part of leaders and followers—based on shared values, universal moral principles and an orientation towards a pro-social behavior serving the common good. However, recent critiques have highlighted the tendency in the relevant literature to overlook the systemic context within which leadership and followership are situated. Given this oversight this paper re-visits a classic (...) piece of ethnography on corporate America: Robert Jackal’s Moral Mazes. Employing concepts from critical realism fused with insights from studies on management and bureaucracy we analyse the key themes from the book pertaining to the nature of the leader–follower dynamic in shareholder capitalism. The analysis highlights the role of bureaucracy and corporate ideology as key elements shaping leader–follower relationships, encouraging a type of morality associated with guarding self-interest whilst undermining relationality. The influence of the structural and cultural context in which leader–follower relations unfold draws attention to morality as relationally contingent as opposed to an ideal state. (shrink)

We study the topological models of a logic of knowledge for topological reasoning, introduced by Larry Moss and Rohit Parikh (1992). Among our results is the confirmation of a conjecture by Moss and Parikh, as well as the finite satisfiability property and decidability for the theory of topological models.
