Los recientes acontecimientos económicos y su trascendental repercusión a nivel mundial, tienen entre alguna de sus más notables consecuencias la caída generalizada en los niveles de consumo. Paralelamente otro de los fenómenos cuasi-globales, el consumo masivo de objetos, se caracteriza cada vez más por la frugalidad de dichos objetos de consumo y la necesidad de sustituirlos por otros que aporten alguna novedad; lo que implica que el consumidor no pueda descansar en sus ansias consumistas. A partir de la unión de (...) estos dos aspectos, crisis económica y consumo posmoderno, se plantea un análisis social de algunos de los aspectos que caracterizan a la sociedad de consumo española en el momento presente y su repercusión en la distribución del gasto.

The origin of eukaryotes is one of the major challenges of evolutionary cell biology. Other than the endosymbiotic origin of mitochondria and chloroplasts, the steps leading to eukaryotic endomembranes and endoskeleton are poorly understood. Ras‐family small GTPases are key regulators of cytoskeleton dynamics, vesicular trafficking and nuclear function. They are specific for eukaryotes and their expansion probably traces the evolution of core eukaryote features. The phylogeny of small GTPases suggests that the first endomembranes to evolve during eukaryote evolution had secretory, (...) and not phagocytic, function. Based on the reconstruction of putative roles for ancestral small GTPases, a hypothetical scenario on the origins of the first endomembranes, the nucleus, and phagocytosis is presented.

The cilium/flagellum is a sensory-motile organelle ancestrally present in eukaryotic cells. For assembly cilia universally rely on intraflagellar transport (IFT), a specialised bidirectional transport process mediated by the ancestral and conserved IFT complex. Based on the homology of IFT complex proteins to components of coat protein I (COPI) and clathrin-coated vesicles, we propose that the non- vesicular, membrane-bound IFT evolved as a specialised form of coated vesicle transport from a protocoatomer complex. IFT thus shares common ancestry with all protocoatomer derivatives, (...) including all vesicle coats and the nuclear pore complex (NPC). This has major implications for the evolutionary origin of the cilium. First, it reinforces the tenet that duplication and divergence of pre-existing structures, rather than symbiosis, were the major themes during cilium evolution. Second, it suggests that the initial step in the autogenous origin of the cilium was the establishment of a membrane patch with transmembrane proteins transported by the ancestral vesicle-coating IFT complex. We propose a scenario for how the initial membrane patch gradually protruded to enhance exposure to the environment, then started to move, and finally compartmentalised to render receptor signalling and ciliary beating more efficient.

La encarnación del Verbo de Dios, que culmina en el misterio pascual de la muerte y resurección de Jesucristo, es el hecho fundamental y la novedad radial del Cristianismo. En la encarnación del Verbo, el Dios infinito y creador se autocomunica amorosamente a lo otro creado, para redención y divinización del hombre, para recapitulación del cosmos.

We examined how the cultural dimension of universalism–particularism influences managers’ attitudes toward relational favoritism. Paradoxically, we found in a survey study that Brazilian and Chinese managers perceived more negative consequences of relational favoritism than did American managers—even though the Brazilians and the Chinese perceived stronger particularistic cultural norms in their countries than Americans did in the United States. We attribute this pattern of results to “cultural reflexivity”—the ability of people from transforming economies to be culturally self-critical during a period of (...) dramatic societal change. This pattern of results also emerged in a scenario study in which we asked these same Brazilian, Chinese, and American participants to assess managerial succession decisions made by a General Manager. We varied the scenarios so that the promoted manager was either a colleague with no pre-existing relation with the GM or a colleague who was a relative, a close friend, from the same town, or from the same school. Consistent with the results of the survey study, we found that perceived cultural norms of particularism were negatively related to perceptions of fairness. In other words, Brazilians and Chinese, even while living in more particularistic cultures, were more harsh in judging relational favoritism. We conclude with a discussion on the implications of these paradoxical relationships. (shrink)

ABSTRACT:U.S. Organizational Sentencing Guidelines provide firms with incentives to develop formal ethics programs to promote ethical organizational cultures and thereby decrease corporate offenses. Yet critics argue such programs are cosmetic. Here we studied bank employees before and after the introduction of formal ethics training—an important component of formal ethics programs—to examine the effects of training on ethical organizational culture. Two years after a single training session, we find sustained, positive effects on indicators of an ethical organizational culture (observed unethical behavior, (...) intentions to behave ethically, perceptions of organizational efficacy in managing ethics, and the firm’s normative structure). While espoused organizational values also rose in importance post-training, the boost dissipated after the second year which suggests perceptions of values are not driving sustained behavioral improvements. This finding conflicts with past theory which asserts that enduring behavioral improvements arise from the inculcation of organizational values. Implications for future research are discussed.

El artículo se enfoca en el dilema al que se enfrentan los gobiernos democráticos para hacer frente a la amenaza del terrorismo. Desde el marco de la filosofía política, el autor busca aportar un enfoque que contribuya a la discusión del tema. Como contexto, toma en cuenta las medidas implementadas después del 11 de septiembre de 2001, por parte de los gobiernos de Estados Unidos de América y de países de Europa para combatir al terrorismo. La mayoría de los gobiernos (...) coincide en que, para garantizar la seguridad de sus ciudadanos frente al peligro del terrorismo, es necesario un recorte de libertades en favor de buscar el fortalecimiento del gobierno.

Self-confidence is associated with many positive outcomes, and training programs routinely seek to build participants’ self-efficacy. In this article, however, we consider whether self-confidence increases unethical behavior. In a series of studies, we explore the relationship between negotiator self-efficacy—an individual’s confidence in his or her negotiation ability—and the use of deception. We find that individuals high in negotiator self-efficacy are more likely to use deception than individuals low in negotiator self-efficacy. We also find that perceptions of the risk of deception (...) mediate this relationship. By identifying negotiator self-efficacy as an antecedent to unethical behavior, our findings offer important theoretical and empirical insights into the use of deception, the role of individual differences in ethical decision making, and the broader consequences of self-confidence in business and society.

Graças ao singular prestígio de que gozava o Portugal quatrocentista na Europa de então, era lógico que as filhas e parentes próximas dos nossos reis fossem pretendidas como esposas de infantes e de príncipes estrangeiros; não seria excepção D. Joana, filha de D. Afonso V e irmã de D. João II. Os seus traços fisionómicos estão patentes na pintura guardada no Museu Nacional de Aveiro, que talvez se possa datar de 1471, ou pouco antes; de um autor anónimo, obedeceu aos (...) princípios da escola do pintor Nuno Gonçalves. Nos séculos XVI e XVII, surgiram diversas figurações pictóricas que representam a princesa vestida com o hábito dominicano.Como seria de prever, logo após a beatificação (1693), em Aveiro surgiu a lembrança de que fosse esculpida em madeira uma imagem de Santa Joana para o culto litúrgico. Posteriormente, ao lado de muitas publicações biográficas, multiplicaram-se as representações de Santa Joana, mesmo além-fronteiras. Refiro especialmente as duas que estão patentes em Roma na igreja de Santo António dos Portugueses.Para abreviar este esboço, detenho-me nos últimos decénios da centúria novecentista. Sobretudo a partir de 1938, deparamos com dezenas e dezenas de representações da Princesa Santa Joana, em diferentes materiais e processos, devidas sobretudo à concepção e à arte de aveirenses; até há barcos moliceiros a vogar na ria, que a ostentam garbosamente nas proas. Para finalizar, refiro uma das estátuas que se erguem no perímetro da cidade de Aveiro; trata-se daquela que se encontra no largo fronteiro à Sé e ao antigo Mosteiro de Jesus, inaugurada em 2002. O seu escultor, Helder Bandarra, exprimiu-a com determinação, perseverança e decisão para viver e anunciar Jesus Cristo. (shrink)

In 2007. Terence Tao wrote on his blog an essay about soft analysis, hard analysis and the finitization of soft analysis statements into hard analysis statements. One of his main examples was a quasi-finitization of the infinite pigeonhole principle IPP, arriving at the "finitary" infinite pigeonhole principle FIPP₁. That turned out to not be the proper formulation and so we proposed an alternative version FIPP₂. Tao himself formulated yet another version FIPP₃ in a revised version of his essay. We give (...) a counterexample to FIPP₁ and discuss for both of the versions FIPP₂ and FIPP₃ the faithfulness of their respective finitization of IPP by studying the equivalences IPP ↔ FIPP₂ and IPP ↔ FIPP₃ in the context of reverse mathematics ([9]). In the process of doing this we also introduce a continuous uniform boundedness principle CUB as a formalization of Tao's notion of a correspondence principle and study the strength of this principle and various restrictions thereof in terms of reverse mathematics, i.e., in terms of the "big five" subsystems of second order arithmetic.

Probablemente nunca la teología sacramental ha tenido un florecimiento tan grande como en este último siglo pero, paradójicamente, esto ha ido unido a un extrañamiento cada vez mayor del hombre respecto a los sacramentos, derivado de cuestionamientos de diversa índole. Este artículo, presentado en las XXX Conversaciones de Salamanca, pretende pasar de los cuestionamientos a las cuestiones actuales de fondo que están en juego en la teología sacramental, para poder ofrecer una propuesta de ense- ñanza renovada de los sacr.

We adapt Streicher and Kohlenbach's proof of the factorization S = KD of the Shoenfield translation S in terms of Krivine's negative translation K and the Gödel functional interpretation D, obtaining a proof of the factorization U = KB of Ferreira's Shoenfield-like bounded functional interpretation U in terms of K and Ferreira and Oliva's bounded functional interpretation B.

The paper offers a detailed investigation of select passages from the Vita II Sancti Remacli, a hagiographic text produced in the diocese of Liège in the last decades of the tenth century. The purpose of this investigation is threefold. First, to illustrate the point that the tenth-century Latin hagiographic texts produced in the diocese of Liège did not display quotations from classical and patristic authors only as petrified forms of frozen ancient wisdom with a merely decorative function, but rather as (...) raw gems which were polished and adjusted to fit seamlessly into a new framework. Thus, they could enhance both the form and contents of texts closely connected to their age’s political and intellectual realities. Second, to show that nineteenth- and twentieth-century editions of such texts can act as distorting mirrors to modern readers and researchers, since, due to an editorial strategy that privileged classical material over its medieval context, the editors sometimes completely neglected how quotations from ancient authors were re-worked by the tenth-century hagiographer following the stylistic requirements of rhymed prose. Third, to suggest as a necessary corrective to this distorting approach a new way of reading and consequently editing these types of texts, which places classical and patristic quotations in their proper context, by paying due attention to manuscript evidence, to the stylistic requirements of their new context, and to the complex functions they play in their new textual environment.

Genuine Paraconsistent logics \ and \ were defined in 2016 by Béziau et al, including only three logical connectives, namely, negation disjunction and conjunction. Afterwards in 2017 Hernández-Tello et al, provide implications for both logics and define the logics \ and \. In this work we continue the study of these logics, providing sound and complete Hilbert-type axiomatic systems for each logic. We prove among other properties that \ and \ satisfy a restricted version of the Substitution Theorem, and that (...) both of them are maximal with respect to Classical Propositional Logic. To conclude we make some comparisons between \ and \ and among other logics, for instance \ and some \s. (shrink)

In memoriam José Arrazola Ramírez The logic $\textbf{G}^{\prime}_3$ was introduced by Osorio et al. in 2008; it is a three-valued logic, closely related to the paraconsistent logic $\textbf{CG}^{\prime}_3$ introduced by Osorio et al. in 2014. The logic $\textbf{CG}^{\prime}_3$ is defined in terms of a multi-valued semantics and has the property that each theorem in $\textbf{G}^{\prime}_3$ is a theorem in $\textbf{CG}^{\prime}_3$. Kripke-type semantics has been given to $\textbf{CG}^{\prime}_3$ in two different ways by Borja et al. in 2016. In this work, we (...) continue the study of $\textbf{CG}^{\prime}_3$, obtaining a Hilbert-type axiomatic system and proving a soundness and completeness theorem for this logic. (shrink)

Resumen El objetivo principal del presente trabajo es analizar la atenuación en los actos asertivos en entrevistas sociolingüísticas a fin de entender cómo se construye la imagen de afiliación en la cultura mexicana. En este trabajo la imagen de afiliación se define como el deseo de ser aceptado por un grupo. Nos interesa determinar si la realización de estos actos asertivos son amenazas eventuales a la imagen social de los informantes y si tienen una función atenuadora. El corpus que se (...) analizó consistió en segmentos seleccionados de 12 entrevistas, 6 de hombres y 6 de mujeres, del corpus oral “El habla de Monterrey–PRESEEA” correspondientes a informantes entre 35 y 54 años que concluyeron sus estudios de licenciatura. El análisis de este corpus oral muestra aspectos importantes, a saber, nos presenta que existen similitudes y diferencias entre los dos grupos pues tanto hombres como mujeres utilizaron la justificación para atenuar su punto de vista. En cuanto a diferencias, las mujeres emplearon más estrategias de atenuación que los hombres. Por otra parte, el análisis de los datos sugiere que la atenuación, como categoría pragmática, contribuye a caracterizar la imagen de afiliación de nuestros informantes. (shrink)

We refute the conjecture that all negative translations are intuitionistically equivalent by giving two counterexamples. Then we characterise the negative translations intuitionistically equivalent to the usual ones.

La logique classique (la logique des mathématiques non-constructives) est plus forte que la logique intuitionniste (la logique des mathématiques constructives). Malgré cela, il existe des copies de la logique classique dans la logique intuitionniste. Toutes les copies habituellement trouvées dans la littérature sont les mêmes. Ce qui soulève la question suivante : la copie est-elle unique? Nous répondons négativement en présentant trois copies différentes.

Information communication technology is spreading fast and wide. Driven by convenience, it enables people to undertake personal tasks and make decisions more easily and efficiently. Convenience enjoys an air of liberation as well as self-expression affecting all areas of life. The industry for children's toys is a major economic market becoming ever more tech-related and drawn into the battle for convenience. Like any other tech-related industry, this battle is about industry dominance and, currently, that involves networked toys. Networked toys aim (...) to enhance convenience for children and parents alike. Increasingly difficult to resist, these convenient networked devices are also a societal game changer. Neatly nestled in a lacuna juris and surrounded by a lack of clinical evidence, networked toys raise complex ethical issues concerning human development. This article lays bare the regulatory nexus for networked toys and invites ethical thinking to fill the gap to ensure sufficient protection for all human developmental stages. Networked toys not only affect but also might interfere with child development. Therefore, the article initially summarises the four key psychological stages through which the neurological development of the human brain processes. Each of these stages involves vital windows for human development in cognitive, emotional and social dimensions. Missing any of these developmental windows changes an individual human for life. The article then takes a look at the two main legal frameworks protecting the stages of human development which are applicable to networked toys: First, the examination of the human rights framework with its major segments emanating from the fundamental rights to privacy for family and home, to a child's education as well as to personal data reveals the use of current networked toys as a shielded part of parenting which tends to be at odds with privacy and data protection requirements. Second, the product liability framework for toy manufacturers requires evidence-based causality for putting a child's safety at risk. Unfortunately, these legal frameworks fail to offer sufficient protection of the human developmental stages. There is a lacuna juris. Although networked toys involve the risk of negatively impacting human development in every dimension, clinical psychological studies are impossible to acquire as court evidence for product liability because they take too long to provide reliable data while exposing several generations of children to the examined risk in the process. Meanwhile the temptation of convenience continues to drive the industry and consumers of networked toys and devices, which are already impacting children of all age groups. Accepting this phenomenon as an element of cognitive dissonance in society and in science falls far short of an appropriate ethical balance. The need for creating such an ethical balance concerning networked toys is all the more imperative because even if the networked toy industry managed to eliminate all psychological risks for human development and every legal conflict with privacy and security, significant ethical and societal risks of networked toys remain due to inevitable technological bias. Against these mounting changes, it is suggested that only an ethical approach of interdisciplinary research and learning seems most promising to develop an appropriate equilibrium between the complex challenges posed by networked toys and the societal values at stake.

BackgroundResearch on prevalence of cognitive frailty phenotypes in community-dwelling older adults in different countries is important to estimate their prevalence and to determine the influence of cognitive reserve and mental health in order to prevent frailty. The aims of this study were to estimate the prevalence of reversible and potentially reversible cognitive frailty in a Portuguese sample of old adults and explore the associations between these phenotypes and demographic, comorbidity, social support, cognitive reserve and mental health factors.MethodsWe assessed frailty in (...) 250 community-dwelling older adults aged 60 years or over without dementia, neurological or psychiatric disorders. Subjective cognitive decline and Mild cognitive impairment were diagnosed according to standard criteria. The questionnaires Charlson Index, Medical Outcomes Study Social Support, Cognitive Reserve Index and General Health were used for assessing comorbidity, social support, cognitive reserve and mental health, respectively.ResultsPrevalence of R-CF was 14%, and that of PR-CF, 15.2%. Cognitive frailty profiles differed significantly in relation to education, comorbidity, mental health, and cognitive reserve, but not in age or sex. Multivariate logistic regression showed that age, sex, comorbidity, social support, mental health, and cognitive reserve together predicted R-CF and PR-CF with significant OR for mental health and cognitive reserve.DiscussionCognitive reserve and mental health are important factors predicting R-CF and PR-CF. We recommend assessing these factors for early detection of cognitive frailty and promoting psychological well-being and lifestyles that increase cognitive reserve in adults. (shrink)

Deception is pervasive in negotiations and organizations, and emotions are critical to using, detecting, and responding to deception. In this article, we introduce a theoretical model to explore the interplay between emotional intelligence (the ability to perceive and express, understand, regulate, and use emotions) and deception in negotiations. In our model, we propose that emotional intelligence influences the decision to use deception, the effectiveness of deception, the ability to detect deception, and the consequences of deception (specifically, trust repair and retaliation). (...) We consider the emotional intelligence of both deceivers and targets, and we consider characteristics of negotiators, their interaction, and the negotiation context that moderate these relationships. Our model offers a theoretical foundation for research on emotions, emotional intelligence, and deception and identifies a potential disadvantage of negotiating with an emotionally intelligent counterpart. Though prior work has focused on the advantages of being and interacting with people high in emotional intelligence, we assert that those most likely to deceive us may also be those highest in emotional intelligence.

This article systematically investigates so-called “truth variants” of several functional interpretations. We start by showing a close relation between two variants of modified realizability, namely modified realizability with truth and q-modified realizability. Both variants are shown tobe derived from a single “functional interpretation with truth” of intuitionistic linear logic. This analysis suggests that several functional interpretations have truth and q-variants. These variants, however, require a more involved modification than the ones previously considered. Following this lead we present truth and q-variants (...) of the Diller-Nahm interpretation, the bounded modified realizability and the bounded functional interpretation. (shrink)
