Este artículo de revisión examina la importancia que tienen las comunidades microbianas que colonizan los ambien­tes y equipos de procesado de alimentos formando biopelículas o biofilms en la persistencia microbiana en la industria alimen­taria y consecuentemente, en la seguridad y la calidad de los alimentos. La atención se centra especialmente en biopelículas formadas por microorganismos no deseados, es decir, microor­ganismos alterantes y patógenos. Se presenta información so­bre la variabilidad intraespecífica en la formación, la ecología y la arquitectura de las biopelículas, (...) y los factores que influyen en su formación. Asimismo, se resume la información disponible sobre nuevos agentes o estrategias para el control de la forma­ción o eliminación de biopelículas. (shrink)

We distinguish two pathways people may follow when they join violent groups: compliance and internalization. Compliance occurs when individuals are coerced to join by powerful influence agents. Internalization occurs when individuals join due to a perceived convergence between the self and the group. We searched for evidence of each of these pathways in field investigations of former members of two renowned terrorist organizations: the Liberation Tigers of Tamil Eelam and Islamist radical groups. Results indicated that ex-fighters joined LTTE for reasons (...) associated with both compliance and internalization but that ex-fighters joined Islamist radical groups primarily for reasons associated with internalization. When compliance occurred, it often took the form of coercion within LTTE but involved charismatic persuasion agents within Islamist groups. This evidence of systematic differences in the reasons why fighters enter violent groups suggests that strategies for preventing radicalization and fostering de-radicalization should be tailored to particular groups.

From the most prominent thinkers in Latin American philosophy, literature, politics, and social science comes a challenge to conventional theories of globalization. The contributors to this volume imagine a discourse in which revolution requires no temporalized march of progress or takeovers of state power but instead aims at local control and the material conditions for human dignity.

The Post-genomic Era includes features both from a methodological and epistemic point of view and from an ontological perspective. Firstly, it incorporates new methods of high-throughput sequencing of DNA and RNA, and the development of complete genomes that allow a precise reference of the molecular results obtained. In addition, from an ontological perspective, the centre of gravity of the molecular processes is placed on the expression of genes, and the way in which such expression is regulated; these features turn the (...) attention towards the study of Gene Regulatory Networks, and in particular to the role of RNA. This new molecular-biological perspective based on new methodologies and approaches is affecting the existing Molecular Genetics Theory including the definition of gen and Central Dogma of Molecular Biology. An important philosophical challenges posed by this new situation is the question whether there is a sophistication of the present theory or a New Theory of Molecular Genetics and whether there is an incommensurability between this theory and the accepted theory. In this work we evaluate these changes in the light of Kuhn’s theory of scientific revolution in order to propose an alternative between a moderate and a strong view. According to the moderate one, the Post-genomic changes do not properly involve a paradigm shift or, if they do, they constitute a minor revolution. The strong view considers that, the anomalies disclosed in the Molecular Genetics Theory at conceptual and methodological level and the Post-genomic changes they lead to suppose a scientific paradigm shift.

This article is a first attempt to line out the conditions under which executives might have a real self-interest in pursuing a broad stakeholder management (SM) orientation to enlarge their power. We suggest that managers have wider latitude of action under an SM approach, even when this is instrumental to financial performance. The causally ambiguity of the performance effects of idiosyncratic relationships with stakeholders not only makes SM strategy difficult for competitors to imitate but also increases managerial discretion. When managers (...) use this situation for their own benefit, they can undermine the purported goals of the SM approach. By analyzing some of the factors that might lead to such disfunctionalities, this article advances a theory of the potential dark side of SM. (shrink)

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

The 3-valued paraconsistent logic Ciore was developed by Carnielli, Marcos and de Amo under the name LFI2, in the study of inconsistent databases from the point of view of logics of formal inconsistency (LFIs). They also considered a first-order version of Ciore called LFI2*. The logic Ciore enjoys extreme features concerning propagation and retropropagation of the consistency operator: a formula is consistent if and only if some of its subformulas is consistent. In addition, Ciore is algebraizable in the sense of (...) Blok and Pigozzi. On the other hand, the logic LFI2* satisfies a somewhat counter-intuitive property: the universal and the existential quantifier are inter-definable by means of the paraconsistent negation, as it happens in classical first-order logic with respect to the classical negation. This feature seems to be unnatural, given that both quantifiers have the classical meaning in LFI2*, and that this logic does not satisfy the De Morgan laws with respect to its paraconsistent negation. The first goal of the present article is to introduce a first-order version of Ciore (which we call QCiore) preserving the spirit of Ciore, that is, without introducing unexpected relationships between the quantifiers. The second goal of the article is to adapt to QCiore the partial structures semantics for the first-order paraconsistent logic LPT1 introduced by Coniglio and Silvestrini, which generalizes the semantic notion of quasi-truth considered by Mikeberg, da Costa and Chuaqui. Finally, some important results of classical Model Theory are obtained for this logic, such as Robinson’s joint consistency theorem, amalgamation and interpolation. Although we focus on QCiore, this framework can be adapted to other 3-valued first-order LFIs. (shrink)

Dentro de la dilatada herencia intelectual que nos ha legado Ratzinger / Benedicto XVI es destacable su aportación a la Teología Fundamental. Su amor y su vasto conocimiento tanto de filosofía como de teología permiten al lector descubrir valiosas herramientas para afrontar problemas actuales. En este caso, proporciona recursos utilísimos para, en primer lugar, analizar la crisis que vive la relación fe-filosofía —la centralidad del guion que la une desde su origen— y, en segundo lugar, muestra posibles caminos para recuperar (...) dicha relación tan esencial para la reflexión teológica y, también, para la vida de la Iglesia.

La violencia contra las mujeres alcanza su expresión más siniestra en el flagelo de nuestro tiempo: el feminicidio. No obstante, la respuesta social e institucional ha sido insólita. Grandes sectores sociales permanecen impasibles ante el aumento de asesinatos cruentos de mujeres y niñas. Inadmisible desde una concepción de humanidad crítica y consciente de sus posibilidades de realización más alta, la misoginia que sostiene el orden social resulta alarmante. El objetivo del trabajo es comprender la estructura simbólica que alienta la violencia, (...) mediante una reflexión crítica sobre sus posibilidades de transformación. La conclusión a la que llega es que, aunque la estructura simbólica de la dominación sexual opera imperceptiblemente para justificar lo que debería ser condenado de forma generalizada, el desarrollo de la sensibilidad actual ofrece una posibilidad de identificar agravios que antes no se reconocían. Palabras clave: Orden simbólico, Violencia, Feminicidio, Hermenéutica, Misoginia. (shrink)

Gene therapy and gene editing are revolutionising the treatment of genetic diseases, most notably haematological disorders. This paper evaluates the use of both techniques in hereditary blood disorders. Many studies have been conducted in this field, especially with gene therapy, with very promising results in diseases such as haemophilia, certain haemoglobinopathies and Fanconi anaemia. The application of these techniques in clinical practice and the foreseeable development of these approaches in the coming years suggest that it might be useful to evaluate (...) the results achieved thus far. It is also essential to reflect on the possible bioethical concerns raised by the use of both techniques, especially in terms of safety issues for patients, potential side effects, treatment duration, accessibility and cost of treatment, and the heritability of genetic changes produced if germline cells are used.

A filosofia prática de Kant, ou seja, o nuclear da sua ética, juntamente com o "primado da razão prática sobre a especulativa" e a "religião nos limites da simples razão", com seu acento no "mal radical", têm inegáveis afinidades com a - e em certos casos influxo da - tradição cristã. O próprio Kant terá em alguns momentos reconhecido isso mesmo. Segundo o autor do presente texto, subsistem, contudo, inegáveis divergências. O artigo, escrito a partir de uma declarada 'simpatia metódica, (...) pretende precisar no possível o alcance de umas e de outras, fazendo sobre o tema um balanço positivo. O autor propõe ainda uma hipótese de leitura do Opus Postumum, reconhecendo aqui uma tentativa por parte de Kant no sentido de purificar o seu "teísmo moral" numa direcção que tão pouco é alheia a importantes intuições cristãs. /// Aim of the article is to show that the practical philosophy of Kant, or, in other terms, the core of his ethics, as is the case with the "primacy of the practical reason over the speculative one" and the "religion within the limits of pure reason", with its accent set upon the idea of "radical evil", have undeniable affinities with -and in certain cases influxes from - the Christian tradition. Kant himself seems to have recognized that much at certain moments. For the author of the article, however, there are a few divergences to be reckoned with. In fact, the article, which is clearly written from the standpoint of a declared methodic sympathy, does whatever is possible in order to determine the reach of the ones and of the others, but in the end concludes that the result is a positive one. The author also suggests a reading hypothesis for the Opus Postumum, acknowledging here an attempt on the part of Kant directed towards a purification of his "moral theism" in a direction that as such is no less close to some very important Christian intuitions.

As religiões podem ser consideradas como sistemas simbólicos mediante os quais os seres humanos ao longo da sua história sempre procuraram encontrar sabedoria em ordem a enfrentar o mal Um olhar pela história das religiões oferece-nos dados que podem ser compreendidos a partir de três tipos ideais de atitude básica em relação ao problema: Ascese, Gnose, Praxis. O Budismo originário, o Maniqueísmo e a religião bí-blico-cristã são exemplificações disso mesmo. Mais do que uma opção pela exclusão, os membros da nossa (...) cultura ocidental iluminada demonstram uma preferência pela atitude práxica. É a partir dela que nos cabe recuperar os valores das outras. Isso é também o que em muitos significa a presença de uma certa nostalgia pela "espiritualidade oriental". Ou ainda, como modesta gnose, a "teodiceia" (porquê tanto mal?): tão pouco prometedora enquanto resposta (teórica), como inevitável enquanto pergunta. /// Religions can be viewed as symbolic systems with which human beings have throughout history sought the wisdom which enables them to face evil. A survey through the history of religions exhibits features which may be brought to three ideal types of basic attitudes: the ascetic, the gnostic and the 'praxical'. Original Buddhism, Manichaeism and the biblical-Christian Religion exemplify them. Men and women of our occidental, enlightened culture need not to take an exclusive option thereabout. They show a preference for the praxical trend, even though at the same time they also retrieve some of the values of the other ones. Signs of this can be seen in the interest of many for 'oriental spirituality' as well as in that sort of modest gnosis which is "theodicee "(Why so much evil?): always unpromising as a theoretical answer and unavoidable as a question. /// Las religiones pueden ser consideradas como sistemas simbólicos con los que los seres humanos hemos buscado en nuestra historia una sabiduría para afrontar el mal.

El Budismo originário, el Maniqueísmo y la Religión bíblico-cristiana los ejemplifican. Más que una opción excluyente, los humanos de nuestra cultura occidental ilustrada tendrán una preferencia por la actitud práxica. Cabe desde ella recuperar valores de las otras.

Materiales para una filosofía de la Religión.-v.1.

El ultimo tercio del siglo XIII es sin duda de los momentos mas trascendentales en la historia del pensamento cristiano. El esfuerzo creador de varias generaciones ha plasmado ya una realizacion madura en la obra de Santo Tomas. El neoplatonismo agostiniano, que es el sustrato comun de ese pensamento, ha recibido por fin en ella la informacion de lo aristotelico en la medida precisa para producir la formula del equilibrio posible. Pero sucede a continuacion un fenomeno historico interamente natural: el (...) mismo impulso creador y sintetizador impide detenerse en esa postura de equilibrio. Los elementos combinados toman mas conciencia de si, quiete depurar y profundizar su propria individualidad. Y surge una tension bipolar, que es ya clasica como etiqueta historica de todo el periodo: el agostinismo y el aristotelismo se disputan el campo del pensamento cristianos. Los incidentes externos de esta contienda entelectual son bien conocidos. Uno de sus resuldados es la formacion, en el seno de las Ordenes mendicantes, de las escuelas de pensamento cuya divergencia doctrinal va a llenar los siglos posteriores de la Escolastica: el tomismo y el escotismo.

In this paper we investigate risk prediction of criminal re-offense among juvenile defendants using general-purpose machine learning algorithms. We show that in our dataset, containing hundreds of cases, ML models achieve better predictive power than a structured professional risk assessment tool, the Structured Assessment of Violence Risk in Youth, at the expense of not satisfying relevant group fairness metrics that SAVRY does satisfy. We explore in more detail two possible causes of this algorithmic bias that are related to biases in (...) the data with respect to two protected groups, foreigners and women. In particular, we look at the differences in the prevalence of re-offense between protected groups and the influence of protected group or correlated features in the prediction. Our experiments show that both can lead to disparity between groups on the considered group fairness metrics. We observe that methods to mitigate the influence of either cause do not guarantee fair outcomes. An analysis of feature importance using LIME, a machine learning interpretability method, shows that some mitigation methods can shift the set of features that ML techniques rely on away from demographics and criminal history which are highly correlated with sensitive features.

La infección por el virus del papiloma humano (VPH) constituye la causa necesaria, aunque no suficiente, de la enfermedad de transmisión sexual más frecuente en el mundo, responsable del 4,5 % de todos los cánceres en ambos sexos. La vacunación frente al VPH, con niveles de eficacia y seguridad similares en ambos sexos, está dirigida básicamente a mujeres, para reducir la incidencia de infección y sus consecuencias, como el cáncer de cérvix. La transmisibilidad del virus en ambos sexos y la (...) inmunidad colectiva que proporciona la vacunación universal hace que su extensión al sexo masculino constituya una cuestión no solo de salud pública, sino también un dilema bioético relacionado con la protección de la salud y la equitativa distribución de los recursos. Este trabajo aborda el análisis bioético de la extensión de la vacunación contra VPH a ambos sexos. (shrink)

Background Even though we are now well into the 21st century and notwithstanding all the abuse to individuals involved in clinical studies that has been documented throughout History, fundamental ethical principles continue to be violated in one way or another. Discussion Here are some of the main factors that contribute to the abuse of subjects participating in clinical trials: paternalism, improper use of informed consent, lack of strict ethical supervision, pressure exerted by health institutions to increase the production of scientific (...) material, and the absence of legislation regarding ethics in terms of health care and research. Are researchers ready to respect fundamental ethical principles in light of the ample window of information provided by individual genomes, while defending the rights of the subjects participating in clinical studies as a major priority? Summary As one of the possible solutions to this problem, education regarding fundamental ethical principles is suggested for participants in research studies as an initial method of cognitive training in ethics, together with the promotion of ethical behavior in order to encourage the adoption of reasonable policies in the field of values, attitudes and behavior.
