Resumen: El propósito del texto es analizar la relación entre cuidado de sí e innovación educativa, considerando que el diálogo y la ironía, son prácticas que posibilitan que el cuidado de sí surja como novedad en la vida del sujeto. Para alcanzar dicho propósito, el texto está dividido en dos apartados, en el primero se revisan las nociones de cuidado de sí e innovación educativa, en el segundo se analizan el diálogo y la ironía. Se acepta que la innovación educativa (...) es esa posibilidad de mantener en novedad el cuidado de sí como transformación de sí. Se asume que diálogo e ironía son experiencia radical en una continua exigencia de reflexión como una manera de habitar la extrañeza y, simultáneamente, bajo el ejercicio pedagógico del ser y hacer de las prácticas educativas. Finalmente se considera al cuidado de sí e innovación educativa como: reflexión y vida en ejercicio. Asumimos que en el diálogo y en la ironía hay un doblez y giro de la atención, la inquietud y el cuidado de sí que lo hacen emerger como innovación educativa. Palabras clave: Cuidado de sí; Innovación educativa; Diálogo; Ironía; Reflexión. Autocuidado e inovação educacional: Diálogo e ironia Resumo: O objetivo do texto é analisar a relação entre o autocuidado e a inovação educativa, considerando que o diálogo e a ironia são práticas que permitem que o autocuidado surja como novidade na vida do sujeito. Para atingir esse objetivo, o texto está dividido em duas seções, na primeira são revisadas as noções de autocuidado e inovação educacional, na segunda analisam-se o diálogo e a ironia. Admite-se que a inovação educacional é a possibilidade de manter o cuidado de si como uma transformação de si como novidade. Assume-se que o diálogo e a ironia são uma experiência radical em uma demanda contínua de reflexão como forma de habitar a estranheza e, simultaneamente, sob o exercício pedagógico do ser e do fazer nas práticas educativas. Por fim, considera-se o autocuidado e a inovação educacional como: reflexão e vida em exercício. Partimos do pressuposto de que no diálogo e na ironia há uma reviravolta de atenção, inquietação e autocuidado que a fazem emergir como inovação educativa. Palavras-chave: Autocuidado; Inovação educacional; Diálogo; Ironia; Reflexão. Self-care and educational innovation: Dialogue and irony Summary: The purpose of the text is to analyze the relationship between self-care and educational innovation, considering that dialogue and irony are practices that allow self-care to emerge as a novelty in the subject's life. To achieve this purpose, the text is divided into two sections, in the first the notions of self-care and educational innovation are reviewed, in the second the dialogue and irony are analyzed. It is accepted that educational innovation is the possibility of keeping care of oneself as a transformation of oneself as novel. It is assumed that dialogue and irony are a radical experience in a continuous demand for reflection as a way of inhabiting strangeness and, simultaneously, under the pedagogical exercise of being and doing in educational practices. Finally, self-care and educational innovation are considered as: reflection and life in practice. We assume that in the dialogue and in the irony there is a twist and turn of attention, restlessness and self-care that make it emerge as an educational innovation. Keywords: Self-care; Educational innovation; Dialogue; Irony; Reflection. Data de registro: 04/07/2022 Data de aceite: 26/10/2022. (shrink)

El presente escrito trata de abordar la relación entre el ser humano y su mundo de productos técnicos mediante la exploración del concepto de desnivel prometeico, acuñado por Günther Anders. De este modo, se llevará a cabo un análisis de correspondencia entre las nociones de Anders y la enajenación marxiana y feuerbachiana, alumbrando así un estudio comparativo de vocación extemporánea y crítica.

How do we acquire a mental representation of our own face? Recently, synchronous, but not asynchronous, interpersonal multisensory stimulation between one’s own and another person’s face has been used to evoke changes in self-identification . We investigated the conscious experience of these changes with principal component analyses that revealed that while the conscious experience during synchronous IMS focused on resemblance and similarity with the other’s face, during asynchronous IMS it focused on multisensory stimulation. Analyses of the identified common factor structure (...) revealed significant quantitative differences between synchronous and asynchronous IMS on self-identification and perceived similarity with the other’s face. Experiment 2 revealed that participants with lower interoceptive sensitivity experienced stronger enfacement illusion. Overall, self-identification and body-ownership rely on similar basic mechanisms of multisensory integration, but the effects of multisensory input on their experience are qualitatively different, possibly underlying the face’s unique role as a marker of selfhood.

In recent decades, Spanish feminist praxis has diversified its theoretical proposals and objectives, presenting the use of the new virtual communities from perspectives that bring it closer both to cyberfeminism and to technofeminism. The purpose of this article is to consider and explore in depth the construction and the use of the new technologies and internet in the new spaces for relationships in this feminist praxis. The article analyses the theoretical and agency proposals presented by two of the founders of (...) the most significant portals in recent years in Spain: E-leusis, founded by María Angustias Bertomeu, and Mujeres en Red, founded by Montserrat Boix. From a position closer to the essential utopia defended by Bertomeu, Spanish feminist praxis has advanced towards a kind of technofeminism that Montserrat Boix herself has transformed into what she has denominated social cyberfeminism.

This work presents and defines three meanings of communication taking into account some of the traditions of thought that founded our field of study. These three conceptions are: communication as an architectonic art; communication as a social force; and communication as the encounter with truth. These three conceptions are considered with regard to several traditions of thought conceptualized in Craig’s (1999) constitutive metamodel of communication theory (rhetorical, sociopsychological, critical and phenomenological). Furthermore, the discussion expands the traditions of thought, adding American (...) pragmatism (Craig’s proposal would be included in it), and a new tradition that highlights the element of undecidability in communication, partly as an extension of phenomenology and partly with its own historical roots in Badiou’s philosophy of the event.

Multisensory stimulation has been shown to alter the sense of body-ownership. Given that perceived similarity between one’s own body and those of others is crucial for social cognition, we investigated whether multisensory stimulation can lead participants to experience ownership over a hand of different skin colour. Results from two studies using introspective, behavioural and physiological methods show that, following synchronous visuotactile stimulation, participants can experience body-ownership over hands that seem to belong to a different racial group. Interestingly, a baseline measure (...) of implicit racial bias did not predict whether participants would experience the RHI, but the overall strength of experienced body-ownership seemed to predict the participants’ post-illusion implicit racial bias with those who experienced a stronger RHI showing a lower bias. These findings suggest that multisensory experiences can override strict ingroup/outgroup distinctions based on skin colour and point to a key role for sensory processing in social cognition.

La obtención de alimentos sanos y seguros requiere de técnicas de conservación inocuas para el consumidor y para el me­dio ambiente, entre las que se destaca la bioconservación. A su ca­tálogo de compuestos naturales o microorganismos, utilizados de forma habitual, la bioconservación ha incorporado recientemente los bacteriófagos y las proteínas fágicas con actividad lítica. La utilización de fagos y endolisinas en el biocontrol ofrece importantes ventajas frente a otros sistemas de conserva­ción tradicionales. Entre dichas ventajas destacan su inocuidad, especificidad y (...) versatilidad. Por otra parte, la acuciante necesidad de reducir el uso de antibióticos en la cadena alimentaria ha impul­sado la investigación basada en estos antimicrobianos con el fin de aplicarlos en producción primaria. Sin embargo, y a pesar de la gran eficacia ya demostrada en múltiples sectores, la falta de legislación de la Unión Europea sobre el uso de bacteriófa­gos junto con la necesidad de ser aceptados por los consumidores, son factores que están afectando negativamente a su implantación como bioconservantes. En este contexto, este artículo recoge los últimos resultados relacionados con este tipo de antimicrobianos en la industria agro-alimentaria, y resume los puntos clave para entender las posibilidades reales de su aplicación ante los nuevos requisitos asociados con una producción sostenible tanto desde una perspectiva económica como ambiental.

Mental body-representations are highly plastic and can be modified after brief exposure to unexpected sensory feedback. While the role of vision, touch and proprioception in shaping body-representations has been highlighted by many studies, the auditory influences on mental body-representations remain poorly understood. Changes in body-representations by the manipulation of natural sounds produced when one's body impacts on surfaces have recently been evidenced. But will these changes also occur with non-naturalistic sounds, which provide no information about the impact produced by or (...) on the body? Drawing on the well-documented capacity of dynamic changes in pitch to elicit impressions of motion along the vertical plane and of changes in object size, we asked participants to pull on their right index fingertip with their left hand while they were presented with brief sounds of rising, falling or constant pitches, and in the absence of visual information of their hands. Results show an "auditory Pinocchio" effect, with participants feeling and estimating their finger to be longer after the rising pitch condition. These results provide the first evidence that sounds that are not indicative of veridical movement, such as non-naturalistic sounds, can induce a Pinocchio-like change in body-representation when arbitrarily paired with a bodily action.

From an early age, exposure to a spoken language has allowed us to implicitly capture the structure underlying the succession of speech sounds in that language and to segment it into meaningful units. Statistical learning, the ability to pick up patterns in the sensory environment without intention or reinforcement, is thus assumed to play a central role in the acquisition of the rule-governed aspects of language, including the discovery of word boundaries in the continuous acoustic stream. Although extensive evidence has (...) been gathered from artificial languages experiments showing that children and adults are able to track the regularities embedded in the auditory input, as the probability of one syllable to follow another syllable in the speech stream, the developmental trajectory of this ability remains controversial. In this work, we have collected Event-Related Potentials while 5-year-old children and young adults were exposed to a speech stream made of the repetition of eight three-syllable nonsense words presenting different levels of predictability to mimic closely what occurs in natural languages and to get new insights into the changes that the mechanisms underlying auditory statistical learning might undergo through the development. The participants performed the aSL task first under implicit and, subsequently, under explicit conditions to further analyze if children take advantage of previous knowledge of the to-be-learned regularities to enhance SL, as observed with the adult participants. These findings would also contribute to extend our knowledge of the mechanisms available to assist SL at each developmental stage. Although behavioral signs of learning, even under explicit conditions, were only observed for the adult participants, ERP data showed evidence of online segmentation in the brain in both groups, as indexed by modulations in the N100 and N400 components. A detailed analysis of the neural data suggests, however, that adults and children rely on different mechanisms to assist the extraction of word-like units from the continuous speech stream, hence supporting the view that SL with auditory linguistic materials changes through development.

BackgroundScientific literature on posttraumatic growth after terrorist attacks has primarily focused on persons who had not been directly exposed to terrorist attacks or persons who had been directly exposed to them, but who were assessed few months or years after the attacks.MethodsWe examined long-term PTG in 210 adults directly exposed to terrorist attacks in Spain a mean of 29.6 years after the attacks. The participants had been injured by a terrorist attack or were first-degree relatives of people who had been (...) killed or injured by a terrorist attack. They completed diagnostic measures of emotional disorders and measures of PTSD and depression symptomatology, optimism, and PTG.ResultsMultiple regression analyses revealed gender differences and a positive linear relationship between PTG and cumulative trauma after the terrorist attack. Some PTG dimensions were significantly associated with PTSD symptomatology, these associations being linear, not curvilinear. However, PTG was not associated with depression symptomatology, diagnosis of emotional disorders, age, elapsed time since the attack, or optimism. In comparison with survivors assessed 18 years after the 1995 Oklahoma City bombing, Spanish victims of terrorism showed higher levels of appreciation of life, but lower levels of relating to others and spiritual change.ConclusionThe findings underscore the influence of gender on PTG and provide support to the hypothesis that some emotional distress may be a necessary condition of PTG. Future studies on PTG after terrorist attacks should take into consideration the characteristics of the terrorist attack itself and the contexts of violence and threat in which it occurred. The political, social, and cultural characteristics of the community affected by it and the profile and characteristics of other traumatic events suffered after the attack should also be taken into account in further research.

Benito Jerónimo Feijoo, el representante más insigne de la filosofía española del siglo XVIII, ahormó un proyecto con importantísimas repercusiones en ámbitos como la ciencia, la política, la literatura, la economía, la teología o la sociedad. Ese compendio de la temprana o primera Ilustración que es el _Teatro crítico universal_ articuló una manera de situarse ante los problemas e inquietudes de su tiempo que llegó a numerosos espacios de debate, pero también de toma de decisiones. Gracias a la extraordinaria difusión (...) del _Teatro_ y de otras de sus obras en la península, en América y en partes de Europa, Feijoo ejerció una enorme influencia intelectual -una autoridad que posiblemente no haya logrado ningún otro autor posterior en lengua española-. Si este marco de reforma que propugnaba acabó logrando sus frutos en el último tercio del siglo XVIII es otro asunto, pero no cabe duda de que Feijoo fue -utilizando conscientemente un anacronismo- el intelectual público de su época.

La literatura en América Latina ha representado, a partir de la segunda mitad del siglo XX, uno de los temas que más preocupan a la sociedad latinoamericana: la heterogeneidad de las culturas que buscan incorporar la modernidad y los avances tecnológicos a las tradiciones y a la cultura popular, lo cual genera la concepción de una identidad en conflicto. En este ensayo se analiza cómo está representado el “sujeto heterogéneo”, término propuesto por Cornejo Polar, en la primera parte de la (...) novela El zorro de arriba y el zorro de abajo, de José María Arguedas, a través del estudio de los diferentes narradores empleados en la narración de la novela propiamente dicha y en los fragmentos del diario del autor, con el propósito de demostrar cómo influye la narración en el proceso de ficcionalización y en la representación de la identidad en conflicto.

Grounded theory, a research method born out of the social sciences field, offers a flexible technique that allows simultaneous data collection and processing. Researchers using this method immerse themselves in an area of study, focusing their observations on the data and taking into consideration not only their own interpretations, but also those of the other subjects involved, in order to strengthen their understanding of the social phenomena under examination. This text briefly describes the concept of grounded theory and uses concrete (...) examples to illustrate how data are analysed from the standpoint of the stereotype as an object of study. La teoría fundamentada, nacida al interior de las ciencias sociales, es un método de investigación que posee una técnica flexible y que realiza simultáneamente la recolección y el procesamiento de los datos. En este método, el investigador se encuentra inmerso en el campo de estudio y sus observaciones se abocan al dato, considerando tanto su interpretación como la de los otros sujetos implicados, con la finalidad de fortalecer la comprensión del fenómeno social investigado. En este texto se describe brevemente la teoría fundamentada y cómo se analizan los datos mediante ejemplos concretos, que se presentan a partir del estereotipo como objeto de estudio. (shrink)

La relación de discrepancia y coincidencia de las causas de muerte entre el diagnóstico clínico y anatomopatológico constituye de forma indirecta un indicador de calidad de la atención médica. Son múltiples los ejemplos de enfermedades descubiertas o esclarecidas gracias a la autopsia, que tiene en la correlación clinicopatológica un basamento fundamental. Se estableció como objetivo de investigación describir los principales vínculos históricos entre las especialidades de medicina interna y anatomía patológica, que tienen como enlace esencial la correlación clínico patológica, atendiendo (...) a que no puede existir contradicción antagónica entre enfermo y enfermedad; la medicina interna y la anatomía patológica no pueden verse aisladas ni separadas. The difference and similarity relationship of death causes between the clinical and anatomy-pathological diagnosis is, indirectly, a medical care quality indicator. Thanks to autopsy, which has the clinical-pathological correlation as a main basis, numerous diseases have been discovered or clarified. Discovering the main historical relations between Internal Medicine and Pathological Anatomy specialties was established as the objective of the research. These specialties have the clinical-pathological correlation as a main link, taking into account that there cannot be a conflicting contradiction between the sick and the disease; Internal Medicine and Pathological Anatomy cannot be seen in an isolated or separate way.

Histamine is a multifunctional biogenic amine with relevant roles in intercellular communication, inflammatory processes and highly prevalent pathologies. Histamine biosynthesis depends on a single decarboxylation step, carried out by a PLP-dependent histidine decarboxylase activity (EC 4.1.1.22), an enzyme that still remains to be fully characterized. Nevertheless, during the last few years, important advances have been made in this field, including the generation and validation of the first three-dimensional model of the enzyme, which allows us to revisit previous results and conclusions. (...) This essay provides a comprehensive review of the current knowledge of the structural and functional characteristics of mammalian histidine decarboxylase.

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.

Membership in voluntary organizations is associated with individual and social benefits. Due to the negative consequences of the global pandemic on older people, and the governmental challenges posed by population aging, voluntary membership is of great importance to society. To effectively promote volunteering among older people, it is necessary to understand the determinants of voluntary membership. This study analyses the influence of individual values—secular/traditional and survival/self-expression–on voluntary membership among European adults. Specifically, it examines which values orient two age groups, as (...) well as men and women toward a certain type of association. The sample of 31,985 comprises 60% of adults aged 50–64 and 40% aged 65–79; of which 56% are women and 44% men. The empirical estimation considers different levels of data aggregation: individual, national and welfare system, therefore multilevel analysis is used as an analytical strategy. Individual-level variables from the Integrated Values Survey and national-level variables from the World Bank and Eurostat are used. The results indicate that traditional and self-expression values promote membership in voluntary organizations in general more than secular and survival values. However, there are differences according to the type of organization. Furthermore, values are found to moderate the effect of age and gender on voluntary membership. (shrink)
