We show that there is a low T-upper bound for the class of K-trivial sets, namely those which are weak from the point of view of algorithmic randomness. This result is a special case of a more general characterization of ideals in $\Delta _2^0 $ T-degrees for which there is a low T-upper bound.

Kuera, A., On relative randomness, Annals of Pure and Applied Logic 63 61–67. It is the aim of the paper to answer a question raised by M. van Lambalgen and D. Zambella whether there can be a nonrecursive set A having the property that there is a set B such that B is 1-random relative to A and simultaneously A is recursive in B. We give apositive answer to this question as well as further information about relative randomness.

With a growing corporate interest in pursuing public goods, numerous firms today endeavor to practice corporate social responsibility. Utilizing a multilevel structural equation modeling approach, we investigated the topic of employees' pro-environmental behavior, contributing to the growing literature on “green” issues in the workplace. We incorporated self-determination theory to examine how individuals' perceptions regarding their corporate environmental policies reflected in firm-level green psychological climate influence their environment-specific self-regulation, and whether support of autonomy, relatedness, and competence psychological needs moderates this relationship. (...) The relationship between environment-specific self-regulation and employees' engagement in pro-environmental behavior was also further explained. Analysis of the data from 649 employees working in 37 major South Korean companies revealed that firm-level green psychological climate is positively related to employees' environment-specific self-regulation and that environment-specific self-regulation is also positively related to their pro-environmental behavior. Moreover, while we found that the positive association between firm-level green psychological climate and employees' environment-specific self-regulation was stronger when they had a higher level of relatedness need satisfaction, interactions between firm-level green psychological climate with autonomy and competence need satisfaction did not demonstrate any significant effects. Theoretical and practical contributions together with suggestions for related future research are discussed as well. (shrink)

We show that certain classes of modules have universal models with respect to pure embeddings: Let R be a ring, T a first‐order theory with an infinite model extending the theory of R‐modules and (where ⩽pp stands for “pure submodule”). Assume has the joint embedding and amalgamation properties. If or, then has a universal model of cardinality λ. As a special case, we get a recent result of Shelah [28, 1.2] concerning the existence of universal reduced torsion‐free abelian groups with (...) respect to pure embeddings.We begin the study of limit models for classes of R‐modules with joint embedding and amalgamation. We show that limit models with chains of long cofinality are pure‐injective and we characterize limit models with chains of countable cofinality. This can be used to answer [18, Question 4.25].As this paper is aimed at model theorists and algebraists an effort was made to provide the background for both. (shrink)

Demuth tests generalize Martin-Löf tests in that one can exchange the m-th component a computably bounded number of times. A set fails a Demuth test if Z is in infinitely many final versions of the Gm. If we only allow Demuth tests such that GmGm+1 for each m, we have weak Demuth randomness.We show that a weakly Demuth random set can be high and , yet not superhigh. Next, any c.e. set Turing below a Demuth random set is strongly jump-traceable.We (...) also prove a basis theorem for non-empty classes P. It extends the Jockusch–Soare basis theorem that some member of P is computably dominated. We use the result to show that some weakly 2-random set does not compute a 2-fixed point free function.

The paper discusses the role of language and culture in the context of quantitative text analysis in psychological research. It reviews current automatic text analysis methods and approaches from the perspective of the unique challenges that can arise when going beyond the default English language. Special attention is paid to closed-vocabulary approaches and related methods, both from the perspective of cross-cultural research where the analytic process inherently consists of comparing phenomena across cultures and languages and the perspective of generalizability beyond (...) the language and the cultural focus of the original investigation. We highlight the need for a more universal and flexible theoretical and methodological grounding of current research, which includes the linguistic, cultural, and situational specifics of communication, and we provide suggestions for procedures that can be implemented in future studies and facilitate psychological text analysis across languages and cultures.

Studie pojednává o významu a smyslu židovského šabatu pro hospodářskou společnost, která ztrácí vědomí sounáležitosti člověka se světem a přírodou. Myšlenkový potenciál šabatu nabízí jedno z podstatných ozdravných východisek pro odcizení člověka a jeho práce. Filozofické hledání smyslu práce a volného času nachází odpověď v rámcovém pojetí smyslu lidské činnosti, pravidelného odpočinku a hodnoty času. Šabat obsahuje poselství pro vnímání světa jako hodnotného prostoru pro život a odpovědnou práci s perspektivou minulosti, přítomnosti a budoucnosti.

Prvými svedkami a neraz aj intelektuálnymi generátormi procesov, ktoré viedli k ustanoveniu sociálno-politických štruktúr klasických gréckych poleis, sú archaickí ly­rici. Medzi najstarších patrí spartský Tyrtaios (1. pol. 7. st. p. n. l.), ktorý vo svojej elégii (zl. 12) ustanovuje za vrcholnú zdatnosť thúridos alké (zúrivú chrabrosť, rázny odpor). Toto slovné spojenie nachádzame už u Homéra, ktorý ním pomenúva jednu z bojov­níckych aretai. Naším cieľom bude komplexne analyzovať 12. zlomok, preskúmať použitie tohto slovného spojenia u oboch básnikov a odhaliť nový kontext, (...) do ktorého ho zasadzuje Tyrtaios. Pokúsime sa tak postihnúť jeden z počiatkov „nového racionálno-politického poriadku“ a ukázať spôsob, akým lyrika transformuje staré epické hodnoty na nové politické. (shrink)

Citizen participation can be considered a key part of public policy making and is also one of the reasons for the growing expert interest in this issue. This article focuses on specific knowledge, socalled “lay knowledge”, which can be identified as knowledge gained from “non experts” through civic participation. The article establishes when and how this type of knowledge enters the policy-making process via specific selected tools and provides practical examples from local and municipal public policy.

A positive answer to a question of M. van Lambalgen and D. Zambella whether there exist nonrecursive sets that are low for the class of random sets is obtained. Here a set A is low for the class RAND of random sets if RAND = RAND A.

This article reconsiders the significance of Theognis’ verses quoted in Plato’s Meno by examining the proposed dilemma in the Theognidea. Firstly, the structure of the dialogue, location of verses, and the dilemma itself are briefly discussed. The article then analyses Theognis’ ‘eugenic’ and ‘didactic’ positions, and suggests that there is no contradiction in the verses from the Theognidea quoted in the Meno, and that Plato was aware of this. The article finally concludes that the pictures of Socrates in Meno and (...) Theognis in the Theognidea are alike in four important aspects: both are sôphrôn, both are personal exponents of dikê by virtue of their life, both are moral heroes striving for the improvement of others, and the result of their efforts has a tragic undertone. By drawing attention to tensions within the Theognidea, Plato may also draw readers’ attention to parallels between Theognis and Socrates as teachers. (shrink)

Štúdia sa zameriava na psychologické a didaktické metódy použité v Platónovom dialógu Menón. S využitím metódy dramatického čítania dialógu autor analyzuje dve kľúčové časti sokratovskej pedagogiky: negatívnu (aporetickú) charakterizovanú elenchom s cieľom nájsť a eliminovať chybné predpoklady, a pozitívnu (euporetickú), ktorej cieľom je pomôcť študentovi nájsť nové riešenia a prostredníctvom argumentácie ho priviesť k lepšiemu porozumeniu problému. V závere autor uvádza, že hlavným cieľom dialógu Menón je ukázať rozdiel medzi „sofistickým“ a „sókratovským“ spôsobom učenia. Zatiaľ čo prvý spočíva v memorovaní (...) autoritatívnych názorov a poznatkov učiteľa, sókratovský je založený na spoločnom hľadaní lepších argumentov. Takáto metóda vedie k lepšiemu porozumeniu v oboch významoch tohto slova – v sociálnom (schopnosť sebaovládania a spolupráce), ako aj poznávacom (schopnosť chápať veci v súvislostiach a otvorenosť k ďalšiemu skúmaniu).

La experiencia de la sexualidad en los espacios de diversión propios de la cultura juvenil es un fenómeno que ha sido muy pocas veces considerado a la hora de construir políticas preventivas dirigidas a este sector en Chile. Es en los escenarios propios de las culturas juveniles, asociados a sus espacios de ocio, particularmente los vinculados al “carrete”, donde los y las jóvenes urbanos/as ensayan y ponen en escena diferentes experiencias de acercamiento a la sexualidad. Por otro lado, es en (...) el carrete y su vínculo con la sexualidad ocasional donde en el mundo juvenil emerge la problemática del cuerpo que se resiste a ser regulado desde una normatividad preventiva que no considera sus propias temporalidades y códigos. El presente artículo muestra los resultados de una investigación etnográfica sobre sexualidad juvenil en cuatro regiones de Chileque, aproximándose a un escenario cultural juvenil asociado a la sexualidad como es el ‘‘carrete’’, intenta aportar a la generación de nuevas aproximaciones preventivas que permitan obtener un mejor conocimiento y comprensión de los contextos y situaciones en que los y las jóvenes ejercitan y desarrollan su sexualidad.

Este trabajo explora el tema de la vivencia conciente del aprendizaje. Específicamente, el momento en que una persona se da cuenta que algo nuevo se está articulando a su experiencia anterior. Desde la psicología del aprendizaje, este fenómeno estás comprendido en el concepto de metacognición. El trabajo aborda la comprensión de este concepto, y elabora los factores favorecedores del aprendizaje. Finalmente aborda los grupos de acción comunitaria como proyectos socioeducativos, abordando la construcción de utopías cotidianas, la resignificación de la historia (...) personal y la construcción de sentidos en el grupo.

This chapter examines Merold Westphal's critique on the works of Calvin Schrag about the relationship of philosophy and a theistic belief in God. It talks about why neither devils speak as atheist nor god as theist. It reveals that God refuses to appear on philosophy's terms because in God's transcendence, God would appear more otherwise than Being. Also, theism does not explain why the divine “otherwise” ultimately signifies that a personally loving Creator and Redeemer in loving unconditionally always already love (...) also impersonally.

The aim of the article is to show that epimeleia heautou – one of the key issues of ancient Greek philosophy – can be found in a tradition which is older than the Socratic one. First, the author outlines modern paradigmatic interpretations of the history of philosophy and tries to offer an alternative interpretation based on Hellenistic tradition influenced by Socrates. Then he explores the texts of archaic lyrics – the elegies of Theognis of Megara. Resulting from the analysis of (...) the problem of Theognis’ seal, and the parallels between Theognis and archaic lawgivers is the author’s conviction, that the Theognidean poetry as a whole represents a coherent socio-political discourse based on the care of the polis. In conclusion the author traces three basic Socratic issues in Theognidean poetry: political action, pedagogy, and love between a men and a boy. (shrink)

Most readers of Habermas would not classify him as an existential thinker. The view of Habermas as a philosopher in German Idealist and Critical traditions from Kant to Hegel and Marx to the Frankfurt School prevails among Continental as much as among analytic philosophers. And the mainstream Anglo-American reception of his work and politics is shaped by the approaches of formal analysis rather than those of existential and social phenomenology or even current American pragmatism. One may argue that both these (...) readings eclipse richer existential dimensions of a thinker who challenges the notorious methodological and political splits among analytic, Continental and pragmatist orientations. I argue that Habermas’ critical relation to Heidegger’s a historical history of Being and his misguided political career cannot explain a competing narrative of his own affirmative appropriation of existential-ethical dimensions of thought and activism. Second, if one sets in the foreground this competing narrative, there emerges a weak thesis, whether or not a plausible complementarity between the communications critical social theory and concrete existential categories can be established. Third, one may inquire further into a stronger thesis whether or not this link must be developed in order to render Habermas’ own theory of a communicatively competent self sufficiently concrete and critical.

Osvald Demuth studied constructive analysis from the viewpoint of the Russian school of constructive mathematics. In the course of his work he introduced various notions of effective null set which, when phrased in classical language, yield a number of major algorithmic randomness notions. In addition, he proved several results connecting constructive analysis and randomness that were rediscovered only much later.In this paper, we trace the path that took Demuth from his constructivist roots to his deep and innovative work on the (...) interactions between constructive analysis, algorithmic randomness, and computability theory. We will focus specifically on Demuth’s work on the differentiability of Markov computable functions and his study of constructive versions of the Denjoy alternative, Demuth’s independent discovery of the main notions of algorithmic randomness, as well as the development of Demuth randomness, and the interactions of truth-table reducibility, algorithmic randomness, and semigenericity in Demuth’s work.

The article examines how urban Mapuche women co-construct discourses about their ethnogenesis process through evaluations and dialogical positioning. The methodology is qualitative with an interpretive design. The collection method was a focus group in which four urban Mapuche women between 25 and 55 years old participated. The analysis was conducted from a Critical Discourse Studies approach that integrates sociopolitical studies of Mapuche history and decolonial perspectives on the formation of ethnic identity, with the analytical tools of the appraisal system within (...) the Systemic Functional Linguistics theoretical framework. The study focuses on the intersubjective meanings of the attitude and engagement to identify evaluations, positions, and voices present in this discursive construction. The results indicate that participants develop discursive strategies of ‘counter-racialization’ to respond to the ‘racialization’ that has shaped their lives. The discursive strategies are collectively constructed through different evaluative micro-maneuvers that are realized in the discursive semantic stratum as couplings of areas of attitude: affect/judgement and affect/appreciation and couplings of the attitude/engagement meanings. Through these discursive strategies, these women re-signify and celebrate their Mapuche identity by embodying a new symbolic territory that allows them to carry their ancestors and spiritual world.

En este artículo el autor desarrolla una mirada de generación y de género al consumo cultural de los jóvenes de sectores medios en Chile, a través de un enfoque no convencional de la diversión nocturna en el contexto postdictadura. El texto profundiza en las formas en que la sociedad se relaciona con los jóvenes y en los nuevos modelos de identidad, haciendo un contrapunto con la socialización que se generaba en el anterior modelo cultural respecto de este grupo etáreo. Se (...) focaliza para su exposición en dos espacios de entretención característicos de la juventud y en los códigos de esta generación. Como una de las conclusiones, destaca un tránsito desde los grupos de referencia a los grupos de consumidores. (shrink)

Humanitarian operations may pose challenges to which armed forces prepared for warfighting seem rather ill-equipped. It is the aim of this article to examine in what way military ethics should be adapted to humanitarian tasks. Two ideal types of military ethics are defined here: warfighting and humanitarian. The warfighting ethic is supposed to maximise the utility of the military in war and combat and to that end utilises the virtues of loyalty and honour. In contrast, humanitarian obligations require to a (...) larger extent the development of personal integrity and an ability to follow one’s own conscience. The adaptation of military ethics is demonstrated in the case studies of the UK armed forces and the German Bundeswehr. Whereas the moral code of the UK armed forces remains anchored in the principles of the warfighting ethic, the case of the Bundeswehr presents a military ethic closely approximating the humanitarian ideal type.

The aim of this article is to show a social role of friendship (filia) in Classical Greece and to discover why, as Aristotle thinks, is filia the greatest good for the polis. The author bases his analysis on a comparison between Plato’s dialogue Lysis and Aristotle’s Politics (namely the book 1 and book 3). He distinguishes four types of filia, and shows the social role played by each one of them: the love of parents to children, the friendship between teenage (...) boys of the same age, the love of elder men to boys, and the friendship between free adult citizens.

The presented paper focuses on the analysis of strategic documents at the level of the European Union concerning the regulation of artificial intelligence as one of the so-called disruptive technologies. In the first part of the article, we outline the basic terminology. Subsequently, we focus on the summarizing and systemizing of the key documents adopted at the EU level in terms of artificial intelligence regulation. The focus of the paper is devoted to issues of personal data protection and cyber security (...) included in these strategic documents. The final part contains recommendations for future research and evaluation of its key features. (shrink)

Nozick (1977) formulated a challenge to Austrians related to the application of the Law of diminishing marginal utility in the context of notion of indifference. To be able to claim that the value or attributed utility of the subsequent units of goods decreases, we must compare comparables, even if deliberate choice means that we have chosen a particular as being value-different. This causes a logical paradox. One cannot be indifferent and demonstrate a particular preference at the same time. It is (...) mutually exclusive. The paper discusses a critique of Wysocki (2021), who proposes a solution to the paradox in terms of a counterfactual perception of the Law. The critique points to the essence of why neo-Misesians cannot resolve the paradox, which lies in the interpretation of the origin of valuation within the particular value scale. The paper offers an alternative solution based on Hayek’s concept of mental order-ness with the implication of the general applicability of the Law to any order in reality. (shrink)

Resumen:En este trabajo se explora la influencia del gerencialismo en las ciencias sociales en las universidades latinoamericanas. En particular, se observa cómo las estructuras y las prácticas de gestión afectan las labores académicas en esta área del conocimiento. Se plantea que el gerencialismo, con su énfasis en la eficiencia y la eficacia, limita el desarrollo de la diversidad teórica y metodológica en la disciplina, favoreciendo enfoques que son fácilmente medibles y, por lo tanto, más alineados con los indicadores de productividad (...) académica. A través de la teoría de Niklas Luhmann, este trabajo ofrece una comprensión de las universidades como sistemas de decisiones. Se analiza cómo estas instituciones gestionan la complejidad a través de programas regulatorios que ordenan sus decisiones en torno a fines específicos determinados por principios como la cuantificación y la burocratización. Finamente, se sugiere la necesidad de revisar los modelos actuales en el contexto de las ciencias sociales de las universidades latinoamericanas donde el pensamiento crítico y el compromiso con las problemáticas sociales deberían jugar un papel central en la definición de su quehacer.Palabras clave: educación superior; gerencialismo; ciencias sociales; Latinoamérica.
