Griselda Pollock provides concrete historical analyses of key moments in the formation of modern culture to reveal the sexual politics at the heart of modernist art, exploring the writings of Elizabeth Siddall, Mary Cassatt and Berthe Morisot.

This article reports the results of an anonymous survey of researchers at a government research institution concerning their perceptions about ethical problems with journal peer review. Incompetent review was the most common ethical problem reported by the respondents, with 61.8% (SE = 3.3%) claiming to have experienced this at some point during peer review. Bias (50.5%, SE = 3.4%) was the next most common problem. About 22.7% (SE = 2.8%) of respondents said that a reviewer had required them to include (...) unnecessary references to his/her publication(s), 17.7% (SE = 2.6%) said that comments from reviewers had included personal attacks, and 9.6% (SE = 2.0%) stated that reviewers had delayed publication to publish a paper on the same topic. Two of the most serious violations of peer review ethics, breach of confidentiality (6.8%, SE = 1.7%) and using ideas, data, or methods without permission (5%, SE = 1.5%) were perceived less often than the other problems. We recommend that other investigators follow up on our exploratory research with additional studies on the ethics of peer review. (shrink)

In this major book, Griselda Pollock engages boldly in the culture wars over `what is the canon?` and `what difference can feminism make?` Do we simply reject the all-male line-up and satisfy our need for ideal egos with an all women litany of artistic heroines? Or is the question a chance to resist the phallocentric binary and allow the ambiguities and complexities of desire - subjectivity and sexuality - to shape the readings of art that constantly displace the present (...) gender demarcations?

The strict lockdown experienced in Spain during March–June 2020 as a consequence of the COVID-19 crisis has led to strong negative emotions. Music can contribute to enhancing wellbeing, but the extent of this effect may be modulated by both personal and context-related variables. This study aimed to analyze the impact of the two types of variables on the perceived efficacy of musical behaviors to fulfill adults’ emotional wellbeing-related goals during the lockdown established in Spain. Personal variables included age, gender, musical (...) training, personality, resilience, and perception of music’s importance. Contextual variables referred to living in a region with a high COVID-19 impact, perception of belonging to a risk group, being alone, having caring responsibilities during confinement, and amount of time of music listening as compared to prior to the crisis. The study was conducted retrospectively during August–December 2020, when the strict lockdown was over in Spain. An online survey was disseminated among the general population and groups of musicians, and the answers of 507 adults were analyzed. Only personal, but not COVID-19 context-related variables, showed an impact on music’s efficacy. The youngest age group of adults and those with musical training reported the highest efficacy of music for wellbeing enhancement, and music’s importance was found to be the main significant predictor of music’s perceived efficacy. Our findings suggest that the people who have been reported to be emotionally more vulnerable during the lockdown, due to either a strong impact on their daily lives or their lower resilience, perceive a higher benefit from musical behaviors. Being musically trained, even for a small number of years, also leads to a perception of higher efficacy of music for the achievement of emotional wellbeing goals. However, this effect is explained by the musically trained individuals’ higher perception of music’s importance. Although musical behaviors can be generally considered as important for wellbeing enhancement, our study highlights who are the potential individuals who could benefit the most from music-related activities for obtaining better levels of wellbeing, at least within the current context of the COVID-19 crisis.

Research has indicated that microRNAs (miRNAs), a special class of non-coding RNAs (ncRNAs), can perform important roles in different biological and pathological processes. miRNAs’ functions are realized by regulating their respective target genes (targets). It is thus critical to identify and analyze miRNA-target interactions for a better understanding and delineation of miRNAs’ functions. However, conventional knowledge discovery and acquisition methods have many limitations. Fortunately, semantic technologies that are based on domain ontologies can render great assistance in this regard. In our (...) previous investigations, we developed a miRNA domain-specific application ontology, Ontology for MIcroRNA Target (OMIT), to provide the community with common data elements and data exchange standards in the miRNA research. This paper describes (1) our continuing efforts in the OMIT ontology development and (2) the application of the OMIT to enable a semantic approach for knowledge capture of miRNA-target interactions.

In recent years, sequencing technologies have enabled the identification of a wide range of non-coding RNAs (ncRNAs). Unfortunately, annotation and integration of ncRNA data has lagged behind their identification. Given the large quantity of information being obtained in this area, there emerges an urgent need to integrate what is being discovered by a broad range of relevant communities. To this end, the Non-Coding RNA Ontology (NCRO) is being developed to provide a systematically structured and precisely defined controlled vocabulary for the (...) domain of ncRNAs, thereby facilitating the discovery, curation, analysis, exchange, and reasoning of data about structures of ncRNAs, their molecular and cellular functions, and their impacts upon phenotypes. The goal of NCRO is to serve as a common resource for annotations of diverse research in a way that will significantly enhance integrative and comparative analysis of the myriad resources currently housed in disparate sources. It is our belief that the NCRO ontology can perform an important role in the comprehensive unification of ncRNA biology and, indeed, fill a critical gap in both the Open Biological and Biomedical Ontologies (OBO) Library and the National Center for Biomedical Ontology (NCBO) BioPortal. Our initial focus is on the ontological representation of small regulatory ncRNAs, which we see as the first step in providing a resource for the annotation of data about all forms of ncRNAs.

La comprensión burguesa de la vida implica alargarla todo lo que se pueda, y posponer y olvidar la muerte. La muerte es para Heidegger la posibilidad más auténtica de la existencia humana. Esto significa que el ser humano existe para morir. El hambre de inmortalidad de Unamuno, su «querer vivir», solo se entiende desde el «tener que morir». La conciencia de esto último es precisamente el sentimiento trágico de la vida que expone Unamuno. La muerte total y radical supone la (...) ausencia de sentido. El hambre de inmortalidad equivale a la pasión por ser, es decir, a una lucha por el sentido de la existencia. La nada nos está esperando, pero Unamuno llama al ser humano a que haga de la muerte una injusticia. Defiende una moral de la esperanza merecida, según la cual el ser humano debe actuar de manera que no merezca morir. Este es el pesimismo creativo que nos da esperanza. La esperanza merecida que supone la pasión por ser es el único fundamento de sentido de la vida humana. Merecer la eternidad y el sentido, no hay otra forma de experimentar la eternidad y el sentido.

The family of discounted Shapley values is analyzed for cooperative games in coalitional form. We consider the bargaining protocol of the alternating random proposer introduced in Hart and Mas-Colell. We demonstrate that the discounted Shapley values arise as the expected payoffs associated with the bargaining equilibria when a time discount factor is considered. In a second model, we replace the time cost with the probability that the game ends without agreements. This model also implements these values in transferable utility games, (...) moreover, the model implements the α\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\alpha$$\end{document}-consistent values in the nontransferable utility setting.

Although it has acquired an extraordinary social diffusion, entrepreneurial education has a certain lack of definition associated with its conceptualisation and meaning. It seems clear that entrepreneurial education is linked to the economic sphere, but it is not limited to the productive sector. The idea of entrepreneurial education has been progressively enriched, being linked to the development of skills for personal growth and social progress. Further clarification of the meaning and scope of entrepreneurial education is, therefore, needed. Thus, it is (...) relevant to analyse entrepreneurial identity in the context of personal identity via the theoretical–explanatory investigation of a model developed in two phases. A critical analysis leads us to study the different factors that intervene in the configuration of this identity in an attempt to construct a systemic map of entrepreneurial action. Between the private and the public, entrepreneurs seek new ways of facing the challenges of our times, trying to find new ways of regenerating the links between individuals and institutions and with society in general. In this sense, we show how entrepreneurial educational ecosystems acquire relevance insofar as they consider the subject as the principle of action rather than merely the result of various contextual factors.

La actitud burguesa ante la muerte es posponerla y olvidarla. El sentido de la existencia, entonces, es alargar la vida todo lo posible. Heidegger entiende la muerte como la posibilidad más auténtica del ser humano: el ser humano está ahí para morir. En Unamuno, el _querer vivir_ del hambre de inmortalidad se funda sobre la conciencia del _tener que morir_; y, a su vez, el _tener que morir_ implica el hambre de inmortalidad. Este es el sentimiento trágico de la vida. (...) La muerte absoluta implica la falta completa de sentido. Así, el ser humano sería una pasión inútil. En el hambre de inmortalidad entonces hay una profunda afirmación del sentido de la vida como lucha por el sentido. Aunque la nada nos espere, hagamos que sea una injusticia, es decir, actúa de modo que no merezcas morir, que merezcas la eternidad y el sentido. Contra el nihilismo metafísico de Mefistófeles, así se fundamenta la esperanza. Por esto, la pasión es útil, porque solo podemos relacionarnos con la eternidad y el sentido mereciéndolos. (shrink)

El presente trabajo ofrece una interpretación hermenéutica del espectáculo Limbo, de la artista mexicana Gabriela Muñoz, también conocida como “Chula the clown”, a partir de los conceptos desierto y exilio, presentes en este ejercicio escénico, así como en el pensamiento de María Zambrano, donde se muestran como un problema filosófico, y en la obra del investigador Ignacio Izuzquiza. Exilio y desierto aparecen también en Esperando a Godot de Samuel Beckett, obra que se revela como influencia del trabajo de Muñoz y (...) con la que comparte algunos signos poéticos. El texto, asimismo, retoma los apuntes de la investigadora Melissa Lima Caminha, principalmente la noción de deconstrucción del clown femenino moderno y la categoría de monstruosidad para hablar de quienes han sido expulsados o expulsadas del grupo social por ser considerados diferentes y con lo cual viven, precisamente, en los linderos del exilio. En Muñoz, como sucede con la tradición clown, esta figura cómica se muestra como símbolo de lo excluido, lo deforme, lo anormal e, incluso, de lo despreciable. A partir de estas claves, la artista muestra el limbo como un estado emocional donde se diluyen las fronteras del tiempo y el espacio, en un ambiente que se mueve entre la desolación y la comicidad.

The foundations of Statistical Mechanics can be recovered almost in their entirety from the principle of maximum entropy. In this work we show that its non-equilibrium generalization, the principle of maximum caliber (Jaynes, Phys Rev 106:620–630, 1957), when applied to the unknown trajectory followed by a particle, leads to Newton’s second law under two quite intuitive assumptions (both the expected square displacement in one step and the spatial probability distribution of the particle are known at all times). Our derivation explicitly (...) highlights the role of mass as an emergent measure of the fluctuations in velocity (inertia) and the origin of potential energy as a manifestation of spatial correlations. According to our findings, the application of Newton’s equations is not limited to mechanical systems, and therefore could be used in modelling ecological, financial and biological systems, among others.

At the beginning of the 18th century, Berkeley believed an anomaly pointed out by Isaac Barrow could be regarded as important evidence against the optical theories that had been established and standardized thanks to the works of Kepler and Newton. In this article, we want to show that Berkeley’s treatment of the Barrovian Case does not falsify these theories. We will contend that the strategy used by Berkeley to resolve the anomaly by alluding to a change of convention is a (...) strategy that the classical theorist could use as well. In other words, the classical theorist could also appeal to a change of convention to deal with the problem. (shrink)

This article presents the analysis of the characteristics of labor well-being in Colombian micro and small enterprises, this was developed through a documentary review from the model of Hoyos (2010), it is a qualitative research, where 42 investigations were collected, which were consulted in databases such as: Science Direct, Refseek, Redalyc, Scielo, Google Scholar and Dialnet, in addition to exploring the repositories of Colombian universities such as: UNAD, Uniminuto, ECCI, Usanbuenaventura, EAFIT, Unipiloto, UGranada, UTecnológica, UJavieriana, UAndes, UCatólica, UNIR, among others, (...) of which, 13 were adjusted with the categories: Practices of Labor Well-being, Theories of Labor Well-being, Needs in Collaborators and Sociodemographic Data, then descriptive synoptic sheets were constructed and then an analysis by category matrix was made, finally, a data analysis was carried out with the ATLAS.ti tool, which allows discerning the object of study through semantic networks. In this order, it is found that activities related to communication, incentives and motivation are part of the activities used as work welfare practices; as for the theoretical positions of well-being at work, the most supported is the one given by the WHO (2010), which is also defined from satisfaction and quality of life; Among the most outstanding needs to develop welfare programs is dissatisfaction in communication with colleagues and managers, ignorance of the responsibilities in their position, among others, on the other hand, there is evidence of a disregard to establish sociodemographic profiles, that is, companies do not consider it when planning or implementing workplace welfare actions. It concludes the need to build labor welfare policies and practices sensitive to the cultural and economic context for Colombian companies, this means recognizing the importance of adaptive and pragmatic approaches in microenterprises and the integration of more structured and theoretical approaches in small enterprises.

En este trabajo se explora una conexión entre el contextualismo y el fiabilismo. El propósito es desarrollar las líneas centrales de un acercamiento contextualista para resolver la crítica internista de que las nociones fiabilistas de justificación y de conocimiento no son adecuadas porque no recogen las intuiciones correspondientes a que un sujeto que está justificado o que sabe es racional y epistemológicamente responsable. Se argumenta que esta crítica y el escepticismo pirrónico comparten un presupuesto común, a saber, la cláusula internista, (...) por lo que, si es posible limitar el alcance de esta cláusula a través del contextualismo distinguiendo dos contextos diferentes, entonces también es posible hacer uso de esta distinción para dar respuesta a la crítica internista al fiabilismo. In this paper, we explore a connection between reliabilism and contextualism. our purpose is to draw up a contextualist approach to solve the critique that the reliabilist notions of justification and knowledge are not satisfactory because there is no room for the intuitions that a subject who is justified or knows is rational and epistemologically responsible. We will argue that this critique and the Pyrrohnian skepticism share the same assumption, viz., the internalist clause. Thus, if it is possible to limit the scope of this clause using contextualism, making a distinction between two different contexts, then it is also possible to use this distinction to offer an answer to the internalist critique to reliabilism.

Inception module is one of the most used variants in convolutional neural networks. It has a large portfolio of success cases in computer vision. In the past years, diverse inception flavours, differing in the number of branches, the size and the number of the kernels, have appeared in the scientific literature. They are proposed based on the expertise of the practitioners without any optimization process. In this work, an implementation of population-based incremental learning is proposed for automatic optimization of the (...) hyperparameters of the inception module. This hyperparameters optimization undertakes classification of the MNIST database of handwritten digit images. This problem is widely used as a benchmark in classification, and therefore, the learned best configurations for the Inception module will be of wide use in the deep learning community. In order to reduce the carbon footprint of the optimization process, policies for reducing the redundant evaluations have been undertaken. As a consequence of this work, an evaluation of configurations of the inception module and a mechanism for optimizing hyperparameters in deep learning architectures are stated. (shrink)

The rapid increase of industry-sponsored clinical research towards developing countries has led to potentially complex ethical issues to assess. There is scarce evidence about the perception of these participants about the ethical compliance, security, and protection. We sought to evaluate and contrast the awareness and perception of participants and non-participants of industry-sponsored research trials on ethical, safety, and protection topics. A Cases-control survey conducted at twelve research sites in México. Previous and current participants of ISRT as well as non-participants with (...) one of four chronic diseases, were asked to complete the survey which focused on ethical compliance and protection issues of ISRT, and the perception of participating in a trial. A total of 604 cases and 604 controls were surveyed. Cases significantly answered that ethics committees are aware of what is happening in studies, and that medical care of industry-sponsored research trials is better than their usual medical care. The same proportion of cases and controls thought patients must receive economical reimbursement for participating in a research study. The informed consent of the pharmaceutical clinical trial was fully read by 90.4% of the cases. Most cases were satisfied or very satisfied with their overall study participation. Previous and current participants of industry-sponsored research trials have a more positive attitude towards ethics committees, the quality of medical care of the research trials, and the main purpose of economical reimbursements, when compared to non-participants.

The use of marginal land (ML) for lignocellulosic biofuel production is examined for system stability, resilience, and eco-social sustainability. A North American prairie grass system and its industrialization for maximum biomass production using biotechnology and agro-technical inputs is the focus of the analysis.

A bio-economic model that maximizes the utility of consumption having the dynamics of MLs and the farmer/producers as (...) dynamic constraints is used to examine the effects of increased conversion efficiency, input costs, risk, and levels of base resources and inputs on the competitive and societal solutions for biomass production. We posit ML abandonment after biofuel production ceases could lead to permanent land degradation below initial levels that prohibit the establishment of the original flora and fauna. (shrink)

This article shows how Adorno and Horkheimer’s project of enlighten the enlightenment has as goal to overcome the dialectic of enlightenment and achieve an enlightenment without domination. The rationalization and disenchantment that define enlightenment have turned everything into an object that can be manipulated by human beings. In the administered world it has even come to reduce the human being itself to an object by means of his identification and deindividualization. This is the death of the human being. Enlightenment has (...) ended up in domination, in a totalitarian system. Auschwitz has represented the culmination of this understanding of thinking as identification. To save enlightenment is to avoid this dialectic of enlightenment, to demythologize the rationalizing enlightenment. This allows an open and altruistic thinking, which is non-identifying, alien to the domain and respectful of the individual human being. (shrink)

Este artículo tiene el objetivo de mostrar que en la filosofía de Ortega y Gasset ciencia (orientada hacia el conocimiento) y sabiduría (orientada hacia lo práctico-existencial) son inseparables. Esto significa que la di-mensión científica o teórica del pensamiento de Ortega no implica la eliminación de su dimensión práctica/existencial. El tema de la filosofía de Ortega como sabiduría es la vida buena y este ideal de vida es lo que Ortega llama ‘vocación’, ser uno mismo, autorrealización. Pero el ‘yo’ es inseparable (...) de la circunstan-cia. Por tanto, para ser yo, para salvarme yo mismo, hay que salvar la circunstancia. Por esta razón es necesa-ria una ciencia de la circunstancia que desvele el sentido (esencia) de este mundo de la vida. En definitiva, la filosofía de Ortega defiende la integración de lo teórico/científico y lo práctico. (shrink)
