Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

The combination of money and intimacy, particularly in the context of paid caring, can be difficult, given the tendency to view them as belonging to separate spheres. This research studied paid caring within the context of breastfeeding and labor support, using 72 interviews with lactation consultants, doulas, clients, and health care professionals, as well as 150 hours of ethnographic observation. Building upon the work of Viviana Zelizer, I examined the relational work of lactation consultants, doulas, and their clients, finding that (...) this process is highly influenced by the way gender is mapped onto the separate spheres dichotomy. Lactation consultants, doulas, and their clients drew boundaries around their social relations to construct them as different from family care in order to legitimate the combination of money and intimacy. Lactation consultants and doulas both experienced tension in determining appropriate transactions and media for their care work, which illustrates how the separate spheres ideology can perpetuate the relative low pay of care work.

In this paper, we introduce the methodology and techniques of meta-argumentation to model argumentation. The methodology of meta-argumentation instantiates Dung’s abstract argumentation theory with an extended argumentation theory, and is thus based on a combination of the methodology of instantiating abstract arguments, and the methodology of extending Dung’s basic argumentation frameworks with other relations among abstract arguments. The technique of meta-argumentation applies Dung’s theory of abstract argumentation to itself, by instantiating Dung’s abstract arguments with meta-arguments using a technique called flattening. (...) We characterize the domain of instantiation using a representation technique based on soundness and completeness. Finally, we distinguish among various instantiations using the technique of specification languages. (shrink)

In this paper we examine ethical issues relevant to conducting mental health research with refugees and immigrant communities that have cultural orientations and social organisation that are substantially different to those of the broader Australian community, and we relate these issues to NH&MRC Guidelines. We describe the development and conduct of a mental health research project carried out recently in Melbourne with the Somali community, focusing on ethical principles involved, and relating these to the NH&MRC National Statement on Ethical Conduct (...) in Research Involving Humans, and the NH&MRC document Values and Ethics: Guidelines for Ethical Conduct in Aboriginal and Torres Strait Islander Health Research.The experience of conducting mental health research with the Somali community highlights the fact that the principles of inclusion and benefit enunciated in the NH&MRC document Values and Ethics are particularly pertinent when conducting research with refugees and immigrant communities that are culturally distant to those of the broader Australian community. These principles inform issues of research design and consent, as well as guiding respectful engagement with the participating community and communication of the research findings. (shrink)

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19.

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

Com recuerdo y fiel homenaje a nuestro genial compatrinta, el ingeniero e inventar santanderino Leonardo Torres Quevedo, THEORIA quiere reeoger hoy en sus páginas dos breves, claros y luminosostextos -el primero sobre máquinas algébricas (1901) y el segundo sobre el alcance de una nueva ciencia: la Automática (1915)- de aquel español itinerante e infatigable que, como muy contadascompatriotas, supo aliar claridad y rlgor lógico en las definiciones de los conceptos básicos y desbordante inventiva creadora en la estricta y audaz (...) aplicación técnica de los mismos.Acompaña a estos textos la inolvidable imagen del primer ajedrecista automático (electromagnetico) concebido y construido por Torres Quevedo, anticipador también en la era electromecanica de los que habían de seguirle en la electrónica e informática y triunfador póstumo, en 1951, en el primer Congreso Cibernético de París, donde fué examinado por el hijo del inventor español y el padre de la Cibernética, Norbert Wiener, tres años después de la aparición en el M.I.T. de la primera edición inglesa de la obra de éste último Cybemetics, or control and communication in the animal and the machine (1948) que iba a inaugurar la era de la Cibernética, anticipada en tantas ideas, muchos decenios antes, por la Automática de nuestro Torres Quevedo.

A lexicon of Hebrew terms and their Romance equivalents from Maimónides’ treatise on logic and philosophy, al-Maqālah fi-ṣināʻat al-manṭiq, circulated in Hebrew aljamiado among Jews and conversos immersed in 15th-century humanism. This lexicon is one of several texts included in a manuscript which also includes literary works by converso authors such as Alfonso de la Torre’s Visión deleytable and Alfonso de Cartagena’s translation of sentenciae by Seneca, as well as three other philosophical lexicons. This collection of texts recorded in MS (...) Parma 2666 reveals that 15th-century Jews and/or conversos –the only people capable of reading the Hebrew aljamiado– read and interpreted De la Torre’s Visión in the context of the Judeo-Arabic philosophical tradition, which is also the basis for Maimónides’ Manṭiq, available in Hebrew and Latin translations. In this article I examine how the philosophic vocabulary developed in al-Manṭiq, accessible in Romance in the lexicons in MS Parma 2666, reflects the Maimonidean epistemology as it survived and developed among 15th-century Jewish and converso readers of the Visión deleytable.

Critical Race Theory (CRT) has its origins in legal analysis but increasingly has been used by educational researchers to analyse the continued salience of institutional racism in educational settings. After providing a brief overview of the history of CRT and the educational issues addressed by critical race theorists, I review two books that explicitly engage critical race theory (CRT). Delgado and Stefancic’s (2001) primer on the CRT literature provides an important backdrop for situating Guinier and Torres’ (2002) ambitious argument (...) for building grassroots social movements around the concept of political race.

Miguel A. De La Torre rejects hope as the ethical basis for a politically effective and truly liberative form of solidarity. Kelly Brown Douglas, on the other hand, articulates a critical retrieval of hope emphasizing the interpretive relationship between the cross, the lynching tree, and the resurrection. Reading De La Torre and Douglas’s works through Natalie Carnes’s theological aesthetics suggests that their respective works can be engaged as “iconoclasms of fidelity,” or the salutary breaking of idolatrous images toward recovering faithful (...) ones. Examining #SprayTheirNames murals that were created in response to state violence against Black people in the United States, I argue that Carnes’s aesthetics framework holds the violence of the crucifixion and promise of resurrection in visual tension, thus decrying violent oppression while offering a beautiful and dangerous memory that catalyzes hope-filled movement in defense of Black lives.

This text constitutes a reflection on politics, women, feminism and the future in the current global crisis. The civilizing crisis is total, universal and unstoppable. Here we try to sketch some ideas of what I think is really at stake: the definition of subject, person and rights, the idea of the future desirable society, and the foundations and regulation of social life, the concept of good life. In the context of an escalating global crisis and the growing feeling of being (...) in transition to nowhere, the question of whether the arrival of this new order will resist our rights is vital, ethical and politically fundamental. This document tries to collaborate with the process of answering it. The order of the world to come is being built today, in increasingly adverse conditions for the rights and freedoms of women and it is important to anticipate the reflection on some of its foreseeable consequences.

In lieu of an abstract, here is a brief excerpt of the content:Got Ethics? Envisioning and Evaluating the Future of Our Guild and DisciplineStacey M. Floyd-Thomas (bio)IN LIGHT OF THE SOCIETY OF CHRISTIAN ETHICS’ TWENTY-First Century and 2020 Initiatives, several ad hoc committees and working groups have examined the fate and future of both the Society and the field of Christian ethics. The stated purposes of these initiatives and their correlative task forces were to think about a new era that (...) is ostensibly different from the state of the discipline of Christian ethics and the demographics of the Society in the past. In effect, each initiative was charged with addressing the evolving needs of our field, particularly giving attention to our mission, membership, meeting, media, management, and mass appeal. There has also been considerable attention paid to our relevance in an academy and society where underrepresented groups of color are no longer minorities in the demographic composition of the United States. Further, numerous discussions have focused on the shifting dynamics of a global and postsecular age. Each initiative therefore chose to focus its attention on the practices of the Society in order to expand our ethical conversations with ethicists in other cultures, traditions, and institutional settings. Finally, each initiative executed its own inventory, and recommendations to the board and membership emerged.The 2016 preconference workshop titled “Got Ethics?” was a roundtable discussion that was an effort to make good on the hard work of those initiatives and the good intentions of the SCE board. Herein four ethicists—namely, Gloria Albrecht, Agnes Chiu, Gary Dorrien, and Miguel De La Torre, joined me in the quest to revisit the implications that a diverse demographic and discipline as well as the developing global context may pose for the future of our scholarship and society. Each panelist stated hard truths for these troubling times that poignantly mark both the crises of theological education and the church, and even more urgently for the future of our discipline and our Society as Christian ethicists. [End Page 195]Gary Dorrien offered a rigorous overview of the history of Christian social ethics that coalesced around the ever-growing gap that threatens its viability:Today, as in previous generations, some ethicists work hard at straddling the divide between social justice activism and disciplinary scholarship. For many of us, our purview consists entirely of ethicists fitting this description. All of us up here work hard at doing both things and we struggle with the trade-offs of doing so. I have completed my assignment and my time is up, but I have a cautionary conclusion. Unlike previous generations of social ethicists, we cannot assume that our field has a future. The existence of our field is in jeopardy except in Catholic institutions. On the road I have talked with many academic administrators who are skeptical that their schools need to teach anything called Christian ethics or comparative religious ethics or social ethics. We cannot settle for merely asserting that our work is relevant and that our field has an established standing. The weight of presumption is shifting against us. The field is shrinking, and we must prove that our work is substantial and relevant.1As Dorrien traces the history of social ethics as a discipline, beginning with the rise of the Social Gospel and its modern social consciousness, he also causes us to reflect on our postmodern consciousness as well. Social ethics began with black and white Social Gospel ministers who preached radical social change; however, Reinhold Niebuhr’s Christian realism tempered this radical vision, moving the discipline in a more moderate direction. Today social ethics remains in a crisis of identity and relevance, caught between the need to establish itself as a discipline in its own right and the ethical exigency of speaking directly to social injustices.As an emerging moral theologian, Agnes Chiu echoes Dorrien’s perspective by asserting thatChristian ethics is a discipline that intersects and calls for Christian engagement with the world. It enables Christianity to be relevant because it deals with issues with which the world wrestles such as justice, conflicts, and human dignity. Theologians have long warned against the danger of irrelevancy and indifference by both our discipline and the... (shrink)

Of the many questions to which the RST has given rise, I should like to single out two groups.

Purpose. The study seeks to clarify the preconditions for moral and legal decision-making based on the identification of axiological foundations that correlate with the moral perceptions of good and evil and psychological phenomena such as emotions. Theoretical basis of the study is to apply comparative, axiological, systemic methods. This methodological approach allows us to analyze and disclose the essence of the process of moral and legal decision-making on the basis of certain axiological prerequisites and enables to substantiate the connection between (...) the axiological and psychological aspects of taking moral and legal decisions. Originality of the work is to broaden the perceptions of the processes and mechanisms for making moral and legal decisions, which are based on the axiological dimension, in particular on the system of reference individual and social values. The study shows that every necessary moral and legal decision taken by a person is futurologically balanced in the emotional sense, rationally reasoned and morally perceptible in the context of man’s beliefs about good and evil, and realized with necessity in the personal system of reference values that determines the style and manner of individual and social behaviour in the context of material and spiritual values and is an axiological foundation for making all types of moral and legal decisions. Conclusions. Moral and legal decision-making is a social process that is connected with such a social essence of a person as rationality, which gives an opportunity to act axiologically. A person makes moral and legal decisions in a complex way, based on the unity of the moral, axiological and psychological aspects of his worldview, which are grounded on the system of reference values.
