In this article I present HYPER-REF, a model to determine the referent of any given expression in First-Order Logic. I also explain how this model can be used to determine the referent of a first-order theory such as First-Order Arithmetic. By reference or referent I mean the non-empty set of objects that the syntactical terms of a well-formed formula pick out given a particular interpretation of the language. To do so, I will first draw on previous work to make explicit (...) the notion of reference and its hyperintensional features. Then I present HYPER-REF and offer a heuristic method for determining the reference of any formula. Then I discuss some of the benefits and most salient features of HYPER-REF, including some remarks on the nature of self-reference in formal languages. (shrink)

Ethical Aspects Related to Nursing Care for Persons with Disabilities: A Qualitative Analysis Aspectos éticos relacionados com a atenção de enfermagem em pessoas com deficiência: uma análise qualitativa The purpose of the study is to describe ethical aspects related to nursing care for persons with disabilities; a population considered socially vulnerable and in conditions of inequality. It corresponds to the first phase of a primary study conducted in Atacama, Chile using a qualitative methodology and content analysis. Nursing graduates are interviewed (...) respecting Ezekiel Emanuel’s ethical criteria. The main findings account for ontological categories such as moral reasoning, value system, nurse-patient relationship model, consequences of the ethical nursing action, strategies to overcome moral conflicts, and barriers in care. It is concluded that caring for people with disabilities is a source of dilemma and moral anguish for nurses, especially when it comes to individuals with sensitive or cognitive disabilities. The paternalistic medical model predominates in the clinical context, limiting the right to autonomy of persons with disabilities. Instrumental values such as efficiency are added to traditional moral values promoted by nurses. Civic values considered fundamental to the challenge of human diversity and life in a democracy are not mentioned.

Este artículo estudia la hipotética penetración del islamismo –vertiente degradada del Islam- en algunos sectores de la extrema izquierda en Latinoamérica y reflexiona sobre su habilidad para desarrollar tanto una teoría como una práctica islamizadas de la revolución. El objetivo de esto es indagar en un aspecto inusual de la seguridad, el factor ideológico, habitualmente soslayado por preferirse los elementos estratégicos y tácticos. Para ello primero se investigan someramente algunos cambios del terrorismo ligados al islamismo en Latinoamérica. Después se analiza (...) la doctrina mediante la que el islamismo puede conectar con la extrema izquierda mediante los conceptos de revolución, guerra revolucionaria, guerra asimétrica y yihad. Finalmente están las conclusiones del artículo. (shrink)

Databases play a fundamental role in today’s world, being used by most companies, especially those that offer services through the Internet. Today there is a wide variety of database models, each adapted for use according to the specific requirements of each application. Traditionally, the relational models with centralized architectures have been used mostly due to their simplicity and general-purpose query language, which made relational systems suitable for almost any application. However, with the growth of the Internet in recent decades, both (...) in the number of users and in the amount of information, those centralized models began to suffer availability and scalability issues. To address those issues, the use of decentralized architectures and alternative database models began to arise, eventually replacing relational databases and centralized architectures when the requirements on availability and scalability are high. Those database models alternative to the traditional relational model are grouped under the name of NoSQL. In this article, we present a NoSQL database developed as an end of degree work, with a flexible data model based on documents and a fully decentralized architecture based on the Gossip protocol for node discovery and a distributed hash table, in particular the rendezvous hashing algorithm, used to distribute and replicate the data across all the nodes. The main goals of the system are to achieve high availability and high scalability. High availability is achieved thanks to the replication of the data, while high scalability is achieved by its decentralized architecture, which allows multiple entry points from the requests, and the data distribution, effectively increasing the database capacity by increasing the number of nodes.

El presente artículo es producto de una investigación multidisciplinaria e interinstitucional, fruto de la alianza entre la Universidad de San Buenaventura Medellín y el Centro de Familia VID-Obra de la Congregación Mariana de Medellín. Surge de una inquietud respecto a la manera en que se aborda la realidad institucional de las madres cabeza de familia, tanto en el ámbito político como empresarial. Para estudiar esta realidad, se partió de un modelo de investigación cualitativo, en donde se hizo una aproximación a (...) la población a partir de un cuestionario que permitiera identificar los roles y percepciones frente al ejercicio de la maternidad y la jefatura femenina, específicamente, cuando se trata de madres trabajadoras. Los resultados arrojados por la investigación permiten obtener una mirada psicosocial de la forma en que se ejerce el rol de madre y de figura de articulación familiar. (shrink)

El objetivo de este artículo es evaluar si la estrategia populista conlleva oportunidades o peligros para la democracia y para ello se analizan los principales elementos del discurso populista a la luz de las intervenciones de dos líderes europeos, Pablo Iglesias y Marine Le Pen. Se sostiene que la estrategia populista no implica por sí misma un riesgo para la democracia sino que depende del tipo de demandas sociales que se articulen y de los valores hegemónicos que se quieran (...) transmitir a la opinión pública. La estructura del artículo es la siguiente: en primer lugar, se realiza una revisión crítica de la literatura sobre populismo; en segundo lugar, se analizan tanto la estructura formal como el carácter vacuo y disputado del discurso populista a partir de las intervenciones de Iglesias y Le Pen; por último, se presentan unas reflexiones finales.

Little is known about employee reactions in the form of un/ethical behavior to perceived acts of unfairness toward their peers perpetrated by the supervisor. Based on prior work suggesting that third parties also make fairness judgments and respond to the way employees are treated, this study first suggests that perceptions of interactional justice for peers (IJP) lead employees to two different responses to injustice at work: deviant workplace behaviors (DWBs) and organizational citizenship behaviors (OCBs). Second, based on prior literature pointing (...) to supervisors as among the most important sources of moral guidance at work, a mediating role is proposed for ethical leadership. The article suggests that supervisors who inflict acts of injustice on staff will be perceived as unethical leaders, and that these perceptions would explain why employees react to IJP in the form of deviance (DWBs) and citizenship (OCBs). Data were collected from 204 hotel employees. Results of structural equation modeling demonstrate that DWBs and OCBs are substantive reactions to IJP, whereas ethical leadership significantly mediates reactions in the form of DWBs and OCBs. Behavioral ethics and managerial implications are discussed. (shrink)

The purpose of this study was to extend the knowledge about why procedural justice has behavioral implications within organizations. Since prior studies show that PJ leads to legitimacy, the author suggests that, when formal regulations are unfairly implemented, they lose their validity or efficacy. This “rule deactivation,” in turn, leads to two proposed destructive work behaviors, namely, workplace deviance and decreased citizenship behaviors. The results support this mediating role of RD, thus suggesting that it forms part of the generative mechanism (...) through which unfair procedures influence ethical behavior within organizations. The author ends the article by discussing behavioral ethics and managerial implications as well as suggestions for future research. (shrink)

Este ensayo parte de una experiencia disruptiva en un aula de bachillerato de un instituto español. En el transcurso de una clase ordinaria de filosofía, un incidente inesperado rompe la definición de la situación, haciendo añicos el consenso de trabajo entre los alumnos y el profesor. Para reconstruir su trasfondo de expectativas, los alumnos se ven forzados a emplear estrategias de acomodación y normalización. En el análisis de esta experiencia disruptiva convergen la fenomenología del mundo social de Alfred Schütz, la (...) etnometodología de Harold Garfinkel y el interaccionismo simbólico de Erving Goffman.This essay starts from a disruptive experience in a Spanish high school classroom. In the course of an ordinary philosophy lesson, an unexpected incident breaks the definition of the situation, smashing the working consensus among students and teacher to smithereens. In order to rebuild their background expectancies, the pupils are forced to resort to accommodation and normalization strategies. The analysis of this disruptive experience is based upon the convergence of Alfred Schütz’s phenomenology of the social world, Harold Garfinkel’s ethnomethodology, and Erving Goffman’s symbolic interactionism.

El autor de este artículo lee el Apologeticum de Tertuliano como un texto de transición ideológica entre los primeros escritos mesiánicos del cristianismo y la teología política del siglo IV, i.e. una obra que fusiona teología imperial y cristianismo. Dejando de lado las disputas teológicas con el judaísmo, Tertuliano propone una discusión frontal con los romanos sobre la relación del concepto de divinidad con el poder político y quiere mostrar que la teología y la ética de los cristianos son mucho (...) más apropiadas para una realidad como el Imperio romano que las que ha impuesto la tradición politeísta. En este razonamiento se destaca la correspondencia entre monoteísmo y monarquía universal. The author of this paper reads Apologeticum by Tertullian as a text of ideological transition between the early messianic Christian writings and political fourth century theology, i.e. a work that combines Imperial theology and Christianity. Leaving apart the theological disputes with Judaism, Tertullian proposes a frontal discussion with the Romans on the relationship of the concept of divinity with political power and wants to show that theology and Christian ethics are much more appropriate for a reality as Roman Empire which has imposed the polytheistic tradition. His argumentation stands out the reciprocation between monotheism and universal monarchy. (shrink)

PurposeAnomic feelings are predicted to play a moderating role in the relationship between organisational justice perceptions and the citizenship use of the organisation's internet access, or cybercivism. The purpose of this paper is to hypothesise that, just as AFs are supported in prior research as able to intensify the negative effects of organisational justice on cyberloafing, they will also intensify the positive effects of OJ on cybercivism.Design/methodology/approachData were collected from 270 of the 1,547 respondents at a public university.FindingsExcept in the (...) case of procedural justice, the results support that AF act as a moderator of the OJ‐cybercivism link because, among employees with comparatively less AF, the perceptions of the OJ under study had a stronger impact on cybercivism.Research limitations/implicationsTo generalise from a convenience sample of 17 per cent to the entire University is unfeasible, let alone the “public sector” as a whole for a whole culture/country. Therefore, the paper only aims to be an early exploration of actual phenomenon, and to provide new insights necessary to understand the impact of pervasive new media and information and communication technologies on individual behaviour in virtual work settings.Practical implicationsThe findings contribute to an improved understanding of the influence of OJ on cybercivism. As a moderator, anomia is supported in our sample as one of the key “controllers” of the OJ predictions on cybercivism and sets a new scenario in seeking electronic business effectiveness. By encouraging convincing values and equity in the workplace, organisational management seems be on the right path to create the proper context for cybercivism to occur.Originality/valueEmployee AFs are shown to be a moderator in the relationship between OJ and cybercivism. This is the first empirical test of this interaction. (shrink)

In recent years, Julien Deonna and Fabrice Teroni have proposed to understand emotions as embodied evaluative attitudes we take towards objects that figure in nonevaluative representational states. Although their account nicely explains some of the key features that emotions are widely taken to have, it runs into a version of what I call the problem of integration. In the case of the attitudinal view, the integration problem takes the form of explaining how, from the point of view of the subject, (...) the bodily responses that make up the attitude part of the emotion and the representational states that provide the particular object of the emotion come to form an intentionally structured unitary experience, that is, one in which the bodily responses are intentionally directed towards the object. I argue that what explains this integration is the way in which the experience of bodily responses and the experience of the representational states interact. This, I propose, produces what I call an experience of convergence. I also suggest that understanding emotional experience in this way not only solves the problem of the integration but also provides a more solid ground for the claim that emotionsquaembodied attitudes are evaluative.

Aura & Transvestment is a transmedia project consisting of a series of generative images, an experimental form of cryptomedia and a video essay. By describing its own powers and contradictions, the work explores notions of value, ownership, authenticity, artificial scarcity and abundance in the digital realm. The project is a critical analysis of non-fungible tokens used as proof of ownership for digital art, taking Walter Benjamin’s concept of aura as a starting point. It argues that, for tokenized art, cryptography serves (...) as an artificial source of auratic power that reverts the political potential of reproducibility falling back to a magical and ritual notion of aura. This time around the ritual performed is that of property, authenticity, ownership, markets and commodification. Finally, the article outlines alternative uses of cryptography and distributed ledger technologies to support artistic labour and proposes transvestment as a temporary counter-action for the reallocation of value from capitalist forms of production and into commons-based models of social coordination. Submitted to this journal is an adaptation of the script for the video essay, alongside other elements of the project. Please visit: https://aura-transvestment.art/. (shrink)

DNA methylation can be considered a component of epigenetic memory with a critical role during embryo development, and which undergoes dramatic reprogramming after fertilization. Though it has been a focus of research for many years, the reprogramming mechanism is still not fully understood. Recent results suggest that absence of maintenance at DNA replication is a major factor, and that there is an unexpected role for TET3-mediated oxidation of 5mC to 5hmC in guarding against de novo methylation. Base-resolution and genome-wide profiling (...) methods are enabling more comprehensive assessments of the extent to which ART might impair DNA methylation reprogramming, and which sequence elements are most vulnerable. Indeed, as we also review here, studies showing the effect of culture media, ovarian stimulation or embryo transfer on the methylation pattern of embryos emphasize the need to face ART-associated defects and search for strategies to mitigate adverse effects on the health of ART-derived children. DNA methylation, critical for embryo development, suffers significant changes after fertilization, including demethylation, remethylation and TET3-mediated oxidation of 5 mC to 5 hmC. In addition to infertility and environmental insults, ART could impact DNA methylation and ART related consequences in the offspring have been reported. (shrink)

En este trabajo proponemos un análisis de los esquemas de argumento por signo que fueron identificados en las etiquetas interpretativas de las exposiciones permanentes de los museos de la región de la Araucanía. Se analizan cualitativa y críticamente tres casos de los veintiún esquemas por signo identificados. Las herramientas teóricas esgrimidas proceden de la pragma-dialéctica y la lógica informal. Nuestro objetivo es caracterizar los esquemas por signo identificados en las etiquetas de las exhibiciones de los museos de la Araucanía, en (...) la búsqueda de orientar su manejo en el diseño de exhibiciones museísticas significativas. Para ello, hemos desarrollado una matriz metodológica que adopta el levantamiento de una estructura argumental. Así, fue posible identificar los puntos de vista como las razones que lo justifican, además de identificar los esquemas argumentativos, a los cuales se les ha aplicado sus respectivas preguntas críticas. El análisis nos permitió concluir que en el empleo del esquema por signo siempre es necesario apoyarse en el entorno cercano donde se maneja el argumento, esto incluye la noción de lugar o de territorio en sus distintos niveles de significación. Asimismo, se ha comprobado como fundamental la incorporación de la tercera pregunta crítica al esquema por signo, la cual hace referencia al contexto donde se presenta el argumento. Por último, se ha detectado que los esquemas considerados complejos también realizan una referencia al lugar, pero con la utilización y combinación de variadas figuras retóricas, como la resignificación o sustitución.
