Resumen: Mediante un ejercicio hermenéutico se sostiene que la identidad personal supera la aporía del tiempo al construirse como relato de ficción. Primero, se plantea que el relato de ficción se inscribe en el círculo de la mimesis; segundo, que la imaginación es la facultad que crea el sentido de la identidad personal como relato de ficción; tercero, que es la imaginación la que establece la relación entre relato de ficción, innovación semántica e identidad personal; y cuarto, que la identidad (...) personal se crea a sí misma por medio de la generación sentido gracias al relato de ficción. Abstract: Through a hermeneutical approach, this paper states that personal identity overcomes the aporetic of time when built as a fictional narrative. First, it proposes that the fictional narrative is inscribed in the mimesis circle. Secondly, that imagination is the faculty that creates the meaning of personal identity as fictional narrative. Thirdly, that it is the imagination that establishes the relation among fictional narrative, semantic innovation, and personal identity. Fourthly, that personal identity as fictional narrative stresses the importance of the narrative, which creates itself as a generator of meanings. (shrink)

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and psychosexual variables and sexual behavior; on the other hand, to review and improve the psychometric properties of the Sexual Motivations Scale and validate it in Spanish. Participants were 805 university students of (...) both sexes, aged between 18 and 26 years, who completed a battery of online questionnaires. Significant associations were found between young people's sexual motives, especially the motives of coping, peer pressure, and enhancement, the sociodemographic variables, sexual behavior, and psychosexual variables. Also, a new structure of the Sexual Motivations Scale was proposed, with the elimination of the factor of Self-Affirmation. The discussion highlights the relevance of the results obtained due to their implications in the promotion of sexual health, in addition to achieving the first instrument validated in Spanish for the evaluation of sexual motivations.

Due to the COVID-19 pandemic, educational centers and universities in Venezuela have closed their physical plants and are migrating to emergency remote education to continue with academic programs. This empirical study aimed to analyze the predictive capacity of academic self-efficacy and emotional intelligence skills on each of the dimensions of psychological well-being. We employed a cross-sectional predictive design. The sample comprised 277 university students, of which 252 were female. Their ages ranged from 18 to 45 years, with a mean of (...) 20.35. Non-probabilistic chance sampling was used. For data collection, we used an anonymous online form, contacted students by mail, and invited them to participate in the study. Questionnaires were available between 217 and 227 days of decreed quarantine in Venezuela. The results indicated average levels of academic self-efficacy, emotional intelligence: clarity, attention y repair, and psychological well-being. We found differences according to sex and age, specifically in emotional regulation and in bonds of psychological well-being favoring men, respectively. Regarding age, statistically significant differences were found in the group of students older than 21 years with higher perception of psychological well-being and in each of its dimensions. Emotional intelligence and academic self-efficacy were found to be significant predictors of psychological well-being and its dimensions, specifically on control, links, projects, acceptance, and total well-being. It was concluded that emotional intelligence and academic self-efficacy are protective psychological resources of psychological well-being that should be promoted at university to mitigate the negative effects of the pandemic on the mental health of young people.

In this work we study the behavior of a time discrete multiregional stochastic model for a population structured in age classes and spread out in different spatial patches between which individuals can migrate. The dynamics of the population is controlled both by reproduction-survival and by migration. These processes take place at different time scales in the sense of the latter being much faster than the former. We incorporate the effect of demographic stochasticity into the population, which results in both dynamics (...) being modelled by multitype Bienaymé–Galton–Watson branching processes. We present a multitype global model that incorporates the effect of both processes and, making use of the existence of different time scales for demography and migration, build a reduced model in which the variables correspond to the total population in each age class. We extend previous results that relate the behavior of the original and the reduced model showing that, given a large enough separation of time scales between demography and migration, we can obtain information about the behavior of the multitype global model through the study of the simpler reduced model. We concentrate on the case where the two systems are supercritical and therefore the expected number of individuals grows to infinity, and show that we can approximate the asymptotic structure of the population vector and the asymptotic population size of the original system through the study of the reduced model.

¿Podemos llamar madre a Dios? Responder a esta pregunta es lo que tratamos de hacer en las siguientes líneas partiendo del estudio de la raíz hebrea "rhm", cuyo significado original es "útero". Comenzamos haciendo un rápido repaso del significado del término y de sus palabras derivadas en los textos bíblicos. Nos centramos en el uso del término por el profeta Isaías y -especialmente- por el profeta de la Consolación. Así, parece que concebir y entender a Dios como madre es algo (...) que forma parte de la revelación. (shrink)

Se presenta un estudio sobre un aspecto de la fundamentación lógica de la Bibliotecología y Estudios de la Información. Por fundamentación lógica se entiende el análisis de las relaciones entre los componentes del aparato teórico de una disciplina. El aspecto que se pretende realizar es el análisis de las relaciones dialécticas entre dichos componentes. Una relación dialéctica es aquella por la cual se infieren unas categorías a partir del análisis de elementos internos y su interrelación presentes en una categoría inicial. (...) Se parte de una categoría primaria, la cual contiene todos los demás elementos de la estructura teórica de la ciencia. A semejanza de Marx quien en su obra “El Capital” comienza con el concepto “mercancía” para después inferir la teoría de la economía capitalista, nosotros partimos del concepto “documento” para obtener la teoría de la Bibliotecología. Finalmente siguiendo el desarrollo dialéctico del conocimiento se transita de la categoría inicial como relación más simple, a la esencia, después a la apariencia y finalmente a la realidad. Se propone como esencia de la Bibliotecología el satisfacer necesidades de información documental, como apariencia el servicio que se presta al público y como realidad a un sistema de información concreto. A LÓGICA DO SISTEMA CATEGORIAL DA BIBLIOTECONOMIA E ESTUDOS DA INFORMAÇÃO DOCUMENTAL: UMA ANÁLISE DIALÉTICA Resumo Apresenta-se estudo de um aspecto da fundamentação lógica da Biblioteconomia e Estudos da Informação. Por fundamentação lógica entende-se a análise das relações entre os componentes do aparato teórico de uma disciplina. O aspecto que se pretende observar compreende a análise das relações dialéticas entre esses componentes. A relação dialética é aquela pela qual algumas categorias são inferidas a partir da análise de elementos internos e suas interrelações presentes em uma categorização inicial. Parte-se de uma categoria principal que contém todos os outros elementos da estrutura teórica da ciência. Como Marx, que na sua obra “O Capital” começa com o conceito de "mercadoria" para daí inferir sua teoria da economia capitalista, partimos do conceito de "documento" para chegar a uma teoria da Biblioteconomia. Finalmente, após o desenvolvimento dialético do conhecimento, transita-se da categoria incial como a relação mais simples, a essência, e daí para a aparência e, finalmente, para a realidade. Propõe-se como essência da Biblioteconomia a satisfação da informação documental, como aparência o serviço que se presta ao público e como realidade os sistemas de informação concretos. (shrink)

El paradigma hermenéutico ha abierto un horizonte amplio a la hora de interpretar y comprender textos, pero ha cerrado las posibilidades existenciales que ya en Ser y tiempo abriera Heidegger. Lo que se intenta aquí es señalar esos presupuestos ontológico-existenciales que indicara acertadamente el filósofo alemán en su momento. El avance que se presenta hace parte del proyecto de investigación “Ontología en América Latina” que lidera el Grupo de Investigación Tlamatinime. La primera parte tiene como objetivo fijar cuatro lineamientos que (...) estructuran la propuesta de una hermenéutica existencial: 1. La disposición afectiva como afectación y responsabilidad. 2. El comprender afectivo. 3. El comprender como interpretación. 4. El sentido. La segunda parte, consiste en presentar lo que se vislumbra por hermenéutica existencial y cuál sería su propósito.

There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries and for different periods of time serve as reference for (...) evaluation. The ultimate conclusion of all of these studies is that there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries. In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method, comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice. (shrink)

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

IntroductionThis study aimed to evaluate, in adults with mild cognitive impairment, the brain atrophy that may distinguish between three AT biomarker-based profiles, and to determine its clinical value.MethodsStructural MRI was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT profiles, namely, A−T−−: normal AD biomarkers; A+T−−: AD pathologic change; and A+T++: prodromal AD. Sensitivity and specificity of these changes were also estimated.ResultsAn initial atrophy in medial temporal lobe areas was found in the A+T−− and (...) A+T++ groups, spreading toward the parietal and frontal regions in A+T++ patients. These structural changes allowed distinguishing AT profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status.ConclusionsMRI is useful in the determination of the specific brain structural changes of AT profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

Self-determination theory considers motivation as a multidimensional phenomenon, with different levels of intensity, purposes, intentions, wills and autonomies. It distinguishes between intrinsic motivation, extrinsic motivation and amotivation. In this paper, we are going to focus on extrinsic motivation, which is related to those tasks that the subject performs without having a purpose in themselves, and which is composed of identified regulation, introjected regulation and external regulation. The aim of this research is to analyse the relationship between them and emotional intelligence (...) in 165 students with university degrees related to Physical Activity and Sport Sciences. The main findings of this work lie mainly in the demonstration of the fact that emotional intelligence is a predictor of identified regulation, introjected regulation and external regulation.

With this volume of the series Logic, Epistemology, and the Unity of Science edited by S. Rahman et al. a challenging dialogue is being continued. The series’ first volume argued that one way to recover the connections between logic, philosophy of sciences, and sciences is to acknowledge the host of alternative logics which are currently being developed. The present volume focuses on four key themes. First of all, several chapters unpack the connection between knowledge and epistemology with particular focus on (...) the notion of knowledge as resulting from interaction. Secondly, new epistemological perspectives on linguistics, the foundations of mathematics and logic, physics, biology and law are a subject of analysis. Thirdly, several chapters are dedicated to a discussion of Constructive Type Theory and more generally of the proof-theoretical notion of meaning.Finally, the book brings together studies on the epistemic role of abduction and argumentation theory, both linked to non-monotonic approaches to the dynamics of knowledge.

The purpose of this paper is to identify the factors that affect the intention to use Big Data Applications in companies. Research into Big Data usage intention and adoption is scarce and much less from the perspective of the use of these techniques in companies. That is why this research focuses on analyzing the adoption of Big Data Applications by companies. Further to a review of the literature, it is proposed to use a UTAUT model as a starting model with (...) the update and incorporation of other variables such as resistance to use and perceived risk, and then to perform a neural network to predict this adoption. With respect to this non-parametric technique, we found that the multilayer perceptron model for the use of Big Data Applications in companies obtains higher AUC values, and a better confusion matrix. This paper is a pioneering study using this hybrid methodology on the intention to use Big Data Applications. The result of this research has important implications for the theory and practice of adopting Big Data Applications. (shrink)
