El lector me permitirá quizá que le explique de entrada el propósito y el alcance de este brevísimo ensayo, anticipándole los temas de las tres partes que lo componen. Primero, explico lo que quiero decir con la expresión «sociedad civil». Con este fin, describo un tipo o carácter ideal de sociedad civil, en torno al cual he organizado un esquema conceptual que utilizo desde hace años en un amplio programa de investigación en ciencia social; y esbozo las líneas de demarcación (...) entre mi uso de esa expresión y otros usos que se han hecho y se hacen tic ella. Segundo, reelaboro el proceso por el que comencé a utilizar este concepto a mediados de los años setenta. Se trata de un esbozo de reconstrucción, hipotético y fragmentario, del contexto de descubrimiento de aquel esquema conceptual. Es un flash back que me lleva de los primeros sesenta a mi libro Estado, burocracia y sociedad civil, que escribí en 1976 . Tercero, tomo nota de los cambios en mi posición a lo largo de estos años, y me interrogo sobre algunos de los problemas que me han llevado de la concepción de 1976 a la que expongo en La primacía de la sociedad civil de 1993 , y en mis trabajos ulteriores, donde hay un desplazamiento sistemático del énfasis de mi trabajo desde lo que Hamo «sociedad civil sensu stricto» hacia la «sociedad civil sensu lato». La explicación podría radicar en la necesidad de revisar, ampliar y formalizar el esquema «acomodándolo»: uno, al proceso en curso de mis trabajos de investigación empírica, y a la importancia creciente en esos trabajos de los temas de autoridad pública, esfera pública y política pública; dos, al horizonte histórico del whithcring away del totalitarismo comunista; y tres, a mi interés creciente en los temas de tradición, instituciones y retórica. Aunque los tres factores están interrelacionados, centraré aquí mi atención sobre todo en el primero de ellos, es decir, en los estímulos para la re-elaboración del esquema originario que han procedido de mi experiencia de investigación empírica, con alguna referencia al segundo, dejando el tercero poco más que aludido.

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)

En el presente artículo se evidencia la vinculación que establece Rama entre lengua/literatura y espacio/poder en La ciudad letrada. Este nuevo paradigma ha permitido pensar y repensar la literatura latinoamericana y los estudios culturales, sin embargo, entraña contradicciones dentro del mismo pensamiento del uruguayo. La tajante división que el autor establece entre ciudad real y ciudad letrada hace imposible pensar el rol de la literatura fuera de la esfera del poder institucional, al mismo tiempo que relega ontológicamente la realidad de (...) esta última a una meramente instrumental. Nuestra propuesta es leer a la luz del concepto de transculturación esta oposición, para establecer una dialéctica que permita considerar la politicidad propia de la ciudad real y su rol activo en la expresión de una literatura de resistencia política.

Recent research has shown that cultural, linguistic, and sociodemographic peculiarities influence the measurement of trait emotional intelligence. Assessing trait EI in different populations fosters cross-cultural research and expands the construct’s nomological network. In mental health, the trait EI of clinical populations has been scarcely researched. Accordingly, the present study examined the relationship between trait EI and key sociodemographic variables on Trait Emotional Intelligence Questionnaire datasets with mental healthcare patients from three different Spanish-speaking countries. Collectively, these datasets comprised 528 participants, 23% (...) from Chile, 28% from Peru, and 49% from Spain. The sociodemographic variables we used for trait EI comparisons were gender, age, educational level, civil status, and occupational status. Analyses involved Multigroup Exploratory Structural Equation Modelling and analysis of covariance. Our results revealed significant between-country differences in trait EI across the studied sociodemographic variables and interactions between these variables. Measurement invariance across the datasets was attained up to the scalar level regarding gender and education, although analyses on age, civil status, and occupation displayed non-invariance. The resultant psychometric evidence supports the suitability of the TEIQue-SF for the accurate cross-cultural assessment of trait EI in mental health settings. It also highlights the importance of incorporating trait EI into extant psychotherapeutic frameworks to enhance non-pharmacological treatment efficacy. (shrink)

La théorie de la décision a inspiré des modèles du risque qui formalisent des choix de comportement dont la diversité tient à des facteurs individuels, sociaux et environnementaux. Comme le droit routier cherche à modifier les comportements, ces modèles ont inspiré des politiques publiques et des réformes juridiques ou judiciaires. Leurs effets sont limités par la diversité des déterminants des comportements et l’éclatement des groupes qui prennent des risques. Ces modèles n’en restent pas moins un guide pertinent pour l’action générale (...) de l’État, surtout si des actions spéciales la complètent. Celles-ci pourraient porter sur des cibles spécifiques avec des démarches appropriées, appuyées par l’éducation et la prévention.The decision-making theory has inspired risk models which formalize behaviour choices. Their diversity is due to individual, social and environmental factors. Since road safety laws aim at changing behaviours, these models have inspired policies as well as legal or judicial reforms. Their effects are limited by the variety of decision factors and the dispersal of risk-taking groups. Yet these models do remain a relevant guide for overall state action, particularly if it is enhanced by special actions. The latter could be aimed at special targets using adequate strategies backed by education and prevention. (shrink)

Resumen: En el presente artículo se evidencia la vinculación que establece Rama entre lengua/literatura y espacio/poder en La ciudad letrada. Este nuevo paradigma ha permitido pensar y repensar la literatura latinoamericana y los estudios culturales, sin embargo, entraña contradicciones dentro del mismo pensamiento del uruguayo. La tajante división que el autor establece entre ciudad real y ciudad letrada hace imposible pensar el rol de la literatura fuera de la esfera del poder institucional, al mismo tiempo que relega ontológicamente la realidad (...) de esta última a una meramente instrumental. Nuestra propuesta es leer a la luz del concepto de transculturación esta oposición, para establecer una dialéctica que permita considerar la politicidad propia de la ciudad real y su rol activo en la expresión de una literatura de resistencia política. Abstract: In the present article we show the relationship that Rama establish between language/power and space/power in the Ciudad Letrada. This new paradigm has allowed us to think and rethink Latin American literature and cultural studies, non the less, it also brings out contradictions inside the own thinking of the Uruguayan author. The strong division that the author establishes between the real city and the literate city does not allow one to think of the role of literature outside the field of institutionalized power, at the same time that he relegates the ontological reality of the latter to a merely instrumental one. Our proposal is to read this opposition in the light of the notion of transculturation, establishing a dialectic that allows us to consider the very policy of the real city and its active role in the expression of a political resistance literature.

From this principle, one can deduce that the properties and laws of complex systems can be explained by the laws and properties of simple systems. On the other ..

La oveja (Ovis aries) es el primer animal domesticado para consumo en un hito histórico que marca el inicio de la sedentarización de las comunidades humanas al comienzo del Neolítico. Durante milenios, fueron semejantes al muflón asiático (Ovis orientalis), su ancestro salvaje. Las razas primitivas supervivientes en el norte de Europa son oscuras, mudan el pelo estacionalmente, tienen cuernos en ambos sexos y apenas producen lana. Los ancestros de las modernas surgieron hace unos 3.500 años. Se seleccionaron para producir lana (...) blanca, que crece indefinidamente y se colecta anualmente. Este proceso coincide con la invención de las tijeras de esquilar y con el descubrimiento de tintes como la púrpura. Solo la lana blanca puede teñirse de cualquier color, permitiendo trasladar al tejido las mismas señales que quizá antes nos pintábamos con ocre sobre el cuerpo. La oveja, un herbívoro social muy manejable, sumaba al suministro de alimento el de una fibra abrigada y modificable en su color distintiva de quienes la visten. Un lienzo en blanco donde trasponer las expresiones estéticas antes restringidas al cuerpo, al arte rupestre y al mobiliar. De ahí que diversas mitologías contemplen una relación simbólica especial con ellas. La revolución estética propiciada por las ovejas blancas zozobra en el siglo XX con la aparición de nuevas fibras y el abaratamiento de otras. Hoy, los arquetípicos y blancos rebaños característicos de la iconografía occidental tienden a una coloración mixta al devaluarse la lana. Otras especies domésticas con fibras que solo recientemente se han apreciado comercialmente, como las cabras de angora (Capra hircus) o las llamas (Lama glama), siguen un proceso idéntico al emprendido con las ovejas hace milenios para tornarse blancas. Presentamos las implicaciones estéticas que han estimulado la selección artificial de ovejas con lanas blancas desde un punto de vista transdisciplinar. Siguiendo la corriente bioevolutiva, que entiende nuestra conducta estética y sus manifestaciones como parte de nuestra etología, veremos cómo ese largo proceso estuvo incentivado por nuestro deseo de teñir los tejidos para expresar un fenotipo extendido creando una nueva señal social. Esa nueva señalización, operante en el plano de la selección sexual, se va complicando al desarrollarse nuestras capacidades simbólicas y tecnológicas, siendo sintomática del entorno causal en el que se produce.

Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish version of the Parental Burnout Assessment across Spanish-speaking countries with two consecutive studies. In Study 1, we analyzed the data through a bifactor model within an Exploratory Structural Equation Modeling on the pooled sample of participants obtaining good fit indices. We then attained measurement invariance across both gender (...) and countries in a set of nested models with gradually increasing parameter constraints. Latent means comparisons across countries showed that among the participants’ countries, Chile had the highest parental burnout score, likewise, comparisons across gender evidenced that mothers displayed higher scores than fathers, as shown in previous studies. Reliability coefficients were high. In Study 2, we tested the relations between parental burnout and three specific consequences, i.e., escape and suicidal ideations, parental neglect, and parental violence toward one’s children. The medium to large associations found provided support for the PBA’s predictive validity. Overall, we concluded that the Spanish version of the PBA has good psychometric properties. The results support its relevance for the assessment of parental burnout among Spanish-speaking parents, offering new opportunities for cross-cultural research in the parenting domain. (shrink)

Trait emotional intelligence concerns people’s perceptions of their emotional functioning. Two studies investigated this construct in surgeons and comparison occupations. We hypothesized that trait EI profiles would differ both within surgical specialties as well as between them and other professions. Study 1 compared the trait EI profiles of four different surgical specialties. There were no significant differences amongst these specialties or between consultant surgeons and trainees in these specialties. Accordingly, the surgical data were combined into a single target sample that (...) was compared against samples of engineers, executives and senior managers, lawyers, junior military managers, nurses, and salespeople. Surgeons scored significantly higher on global trait EI than junior military managers, but lower than executives and senior managers, salespeople, and nurses. There were no significant differences vis-à-vis engineers or lawyers. A MANOVA confirmed a similar pattern of differences in the four trait EI factors. Global trait EI scores correlated strongly with single-question measures of job satisfaction and job performance in the surgical sample. These findings suggest that interventions to optimize the trait EI profiles of surgeons can be helpful in relation to job satisfaction, job performance, and overall psychological wellbeing. (shrink)

We study the theories I∇n, L∇n and overspill principles for ∇n formulas. We show that IEn ⇒ L∇n ⇒ I∇n, but we do not know if I∇n L∇n. We introduce a new scheme, the growth scheme Crγ, and we prove that L∇n ⇒ Cr∇n⇒ I∇n. Also, we analyse the utility of bounded collection axioms for the study of the above theories.

Requiring family authorization for apnea testing subtracts health professionals control over death determination, a procedure that has traditionally been considered a matter of clinical expertise alone. In this commentary, we first provide evidence showing that health professionals’ (HPs) disposition to act on death determination without family’s prior consent could be much lower than that referred to by Berkowitz and Garrett (2020). We hypothesize that HPs may have reservations about their own expertise as regards death, and may thus hesitate to impose (...) their views on patients’ families. We then address the theoretical question of clinical expertise in death determination by distinguishing judgments about facts (e.g., the presence or absence of spontaneous breathing) from interpretations given of these facts (i.e., their meaning for the vital status of an individual). We argue that, while clinicians may claim some expert authority on the former, they hold no particular authority on the latter. (shrink)

Despite the promises made by molecular evolutionists since the early 1960s that phylogenies would be readily reconstructed using molecular data, the construction of molecular phylogenies has both retained many methodological problems of the past and brought up new ones of considerable epistemic relevance. The field is driven not only by changes in knowledge about the processes of molecular evolution, but also by an ever-present methodological anxiety manifested in the constant search for an increased objectivity—or in its converse, the avoidance of (...) subjectivity.This paper offers an exhaustive account of the methodological and conceptual difficulties embedded in each of the steps required to elaborate molecular phytogenies. The authors adopt a historical perspective on the field in order to follow the development of practices that seek to increase the objectivity of their methods and representations. These include the adoption and development of explicit criteria for evaluation of evidence, and of procedures associated with methods of statistical inference, quantification and automation. All these are linked to an increasing use of computers in research since the mid 1960s. We will show that the practices of objectivity described are highly dependent on the problems and tools of molecular phylogenetics. (shrink)

The debate over the determination of death has been raging for more than fifty years. Since then, objections against the diagnosis of brain death from family members of those diagnosed as dead-have been increasing and are causing some countries to take novel steps to accommodate people’s beliefs and preferences in the determination of death. This, coupled with criticism by some academics of the brain death criterion, raises some questions about the issues surrounding the determination of death. In this paper, we (...) discuss some of the main approaches to death determination that have been theoretically proposed or currently put into practice and propose a new approach to death determination called "weak pluralism" as a reasonable ethical and political alternative to respect diversity in death determination.

El propósito de este texto es aclarar la dirección, los alcances y los límites del análisis filosófico según lo concibe Peter Strawson en Análisis y metafísica. Para el autor el análisis filosófico asume la forma de una metafísica descriptiva, esto es, de una teoría que exhibe cuáles son, y cómo se relacionan, los distintos elementos que componen nuestro esquema conceptual ordinario. Para lograr tal teoría descriptiva se debe adoptar un estilo de análisis que el autor denomina conectivo, cuya meta es (...) identificar cuáles conceptos, al interior de nuestro esquema son básicos o fundamentales. A este fin deberán aplicarse tres criterios: generalidad, irreductibilidad y no contingencia. (shrink)

Este trabajo aborda el pacto librepensador suscri­to por las autoras Rosario de Acuña y Ángeles López de Ayala. Se examinan sus contribuciones en la prensa librepensadora y su activismo feminista a través de un análisis de sus colabora­ciones en Las dominicales del librepensamiento, El gladiador: órgano de la “Sociedad progresiva femenina” y El gladiador del librepensamiento. La ideología de estas publicaciones les permitió vincular la lucha feminista con la agenda política de ideología progresista. Se parte de dos ejes complementarios cuya (...) intersección permite abordar su pacto de compromiso y transgresión: la lucha por la igualdad social y por la igualdad de género. Se estudian sus reflexiones sobre la explotación del pueblo por las castas, el empoderamiento de la mujer como agente constructor del progreso y la denuncia vehemente de su sometimiento. Se concluye que los escritos de Acuña y Ayala evidencian con el paso de los años una radicalización que pro­picia una postura cada vez más trasgresora y un feminismo más combativo, reflejando así su descontento con la actitud pater­nalista u hostil del librepensamiento y el republicanismo mas­culino en lo que respecta a los derechos de la mujer.

Las crisis económicas están generando desigualdades, producto de la violencia estructural; éstas están derivando en las maneras en que los jóvenes construyen y dibujan los sentidos sociales. Los jóvenes deberían ser sujetos que se mueven en toda una temporalidad sin embargo, sus condiciones materiales de vida, no les permiten pensar en un futuro con certezas. Más bien, éstas se desdibujan para ellos y hoy más que nunca aparecen sus sueños postergados y aplazados por la propia violencia de la que son (...) objeto. De ahí, nuestro interés en ver cómo los jóvenes egresados de la universidad, están construyendo dichos sentidos.Economic crises are generating inequalities resulting from structural violence; they are drifting in the ways in which young people build and draw social senses. Young people should be the subjects of movement along temporariness; nevertheless, their material living conditions do not allow them to think in their future with certainty. For our young generations these conditions are blurred, and now more than ever their dreams are deferred and delayed by the violence they are subjected to. Hence, our interest in finding out how young university graduates are building these senses. (shrink)

BackgroundInformed consent is an important factor in a child’s moral structure from which different types of doctor–patient relationships arise. Children’s autonomy is currently under discussion in terms of their decent treatment, beyond what doctors and researchers perceive. To describe the influential practices that exist among clinicians and researchers toward children with chronic diseases during the process of obtaining informed consent.MethodsThis was a cross-sectional, qualitative study via a subjective and interpretivist approach. The study was performed by conducting semi-structured interviews of 21 (...) clinicians and researchers. Data analysis was performed using the SPSS version 21® and Atlas Ti version 7.0® programs.ResultsThe deliberative and paternalistic models were influential practices in the physician–patient relationship. In the deliberative model, the child is expected to have a moral awareness of their care. The paternalistic model determined that submission was a way of structuring the child because he or she is considered to be a subject of extreme care.ConclusionsThe differentiated objectification [educational] process recognizes the internal and external elements of the child. Informed consent proved to be an appropriate means for strengthening moral and structuring the child. (shrink)

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)

Los movimientos sociales (MS) son acciones colectivas reiteradas, de confrontación o desborde de las instituciones, con expresiones más o menos organizadas en torno a una reivindicación. Acciones sostenidas de reclamos y demandas, que no se identifican con las instituciones que los generan. La comunicación desde la perspectiva del sujeto se convierte en vehículo de las demandas. La comunicación popular fortalece la acción colectiva interna, mientras que, por otro lado, los medios masivos desarticulan la imagen de los sujetos enfatizando sus intereses (...) al servicio de empresas, corporaciones y conglomerados. Algunas experiencias en el medio rural uruguayo, nos permiten reflexionar: ¿Es posible que los MS sean espacios educativos y constituyan sujetos pedagógicos? ¿Qué función cumple la comunicación popular al interior y al exterior de los MS? ¿Cómo abordar a los medios masivos que banalizan y distorsionan la lucha de los MS? El estudio de los MS ¿es una tarea académica o militante? (shrink)

ArgumentThis paper analyzes the research strategies of three different cases in the study of human genetics in Mexico – the work of Rubén Lisker in the 1960s, INMEGEN's mapping of Mexican genomic diversity between 2004 and 2009, and the analysis of Native American variation by Andrés Moreno and his colleagues in contemporary research. We make a distinction between an approach that incorporates multiple disciplinary resources into sampling design and interpretation (unpacking), from one that privileges pragmatic considerations over more robust multidisciplinary (...) analysis (flattening). These choices have consequences for social, demographic, and biomedical practices, and also for accounts of genetic variation in human populations. While the former strategyunpacksfine-grained genetic variation – favoring precision and realism, the latter tends toflattenindividual differences and historical depth in lieu of generalization.

Altruism and solidarity are concepts that are closely related to organ donation for transplantation. On the one hand, they are typically used for encouraging people to donate. On the other hand, they also underpin the regulations in force in each country to different extents. They are often used indistinctly and equivocally, despite the different ethical implications of each concept. This paper aims to clarify to what extent we can speak of altruism and solidarity in the predominant models of organ donation. (...) It also raises the ethical question of whether these categories are adequate as a basis for such models, bearing in mind that organs are a scarce resource and that a shortage of them may mean that fewer lives are saved or improved.
