Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Este artículo examina cómo la separabilidad y unidad mente-cuerpo resultan clave para poner de manifiesto lo inapropiado del “teatro cartesiano”, metáfora creada por Daniel Dennett para criticar la experiencia consciente unificada en Descartes. La primera sección introduce al problema de la separabilidad cartesiana. La segunda examina cómo mente y cuerpo, separables mediante lo concebible según Descartes, resultan ser cosas metafísicamente distintas. La tercera enfatiza como separables no implica separados. La última sección enfatiza el argumento de la dis-analogía del piloto (...) y el navío, y cómo, según el filósofo francés, aunque separables, mente y cuerpo son substancias estrechamente unidas, formando un ens per se. En vista de este, criticamos la metáfora del “teatro cartesiano” de Dennett: es imposible que la mente sea un espectador, puesto que la experiencia consciente ya es unificada e incluso somatizada. Notamos, por último, que pese a Dennett, hay investigadores de la Ciencia Cognitiva que coinciden con Descartes en relación con la estrecha unión mente-cuerpo, i.e., quienes defienden que la mente es encarnada, incrustada o incluso extendida.

La ideación artística y arquitectónica está en gran medida configurada a partir de un concepto o metáfora que rige los diseños como síntesis de nuestro pensamiento y que, posteriormente, se ve confrontada con el lugar, creando con ello una cierta tensión entre paisaje e intervención proyectual. Este artículo explora el concepto de «corte» de Sverre Fehn, tomado como elemento simbólico de resistencia ligado al tiempo, al lugar y a la memoria, como idea generatriz, basada en analogías conceptuales que el artista (...) aplicaba en sus proyectos. Así, un simple gesto, una grieta, una hendidura o incluso un vacío en el terreno, es tomado como memoria pues, de algún modo, configura la idea del lugar que recorremos con la mirada y remite al testimonio de otro tiempo mientras lo experimentamos en diálogo permanente con el paisaje en el que se inscribe. Se crea así una relación intensa entre luz, espacio, materia y memoria con el horizonte paisajístico, como límite de la obra. Este artículo realiza un recorrido por diferentes obras artísticas, arquitectónicas e incluso patrimoniales. Su denominador común es el concepto «corte», un elemento de permanencia que facilita una lectura integradora desde el proyecto, en un intento por cruzar e, incluso, vincular el lenguaje empleado entre las disciplinas para diluir las fronteras, traspasar los límites, recobrar la memoria y establecer, como diría Rosalind Krauss, un nuevo «territorio expandido».

We propose a characterization of mathematical experiments in terms of a setup, a process with an outcome, and an interpretation. Using a broad notion of process, this allows us to consider arithmetic calculations and geometric constructions as components of mathematical experiments. Moreover, we argue that mathematical experiments should be considered within a broader context of an experimental research project. Finally, we present a particular case study of the genesis of a geometric construction to illustrate the experimental use of hand drawings (...) and computers in mathematical practice. (shrink)

En el siguiente artículo analizamos las diferentes aportaciones que, desde Nietzsche y Husserl hasta los estudios de Freud, han servido para trazar una genealogía de la imagen. Ello nos permitirá examinar cuáles han sido los enfoques que se han ocupado de la imagen, los puntos de conexión entre diferentes teorías y los conflictos epistemológicos de cada posicionamiento.In the following paper we analyze the different contributions that, from Nietzsche and Husserl to Freud’s studies, have served to trace a genealogy of image.

Weisberg and Muldoon’s epistemic landscape model (ELM) has been one of the most significant contributions to the use of agent-based models in philosophy. The model provides an innovative approach to establishing the optimal distribution of cognitive labor in scientific communities, using an epistemic landscape. In the paper, we provide a critical examination of ELM. First, we show that the computing mechanism for ELM is correct insofar as we are able to replicate the results using another programming language. Second, we show (...) that small changes in the rules that determine the behavior of individual agents can lead to important changes in simulation results. Accordingly, we claim that ELM results are robust with respect to the computing mechanism, but not necessarily across parameter space. We conclude by reflecting on the possible lessons to be gained from ELM as a class of simulations or cluster of models. (shrink)

We define and study the notion of an indexed frame. This is a bi-dimensional structure consisting of a Cartesian product equipped with relations which only relate pairs if they coincide in one of their components. We show that these structures are quite ubiquitous in modal logic, showing up in the literature as products of Kripke frames, subset spaces, or temporal frames for STIT logics. We show that indexed frames are completely characterised by their ‘orthogonal’ relations, and we provide their sound (...) and complete logic. Using these ‘orthogonality’ results, we provide necessary and sufficient conditions for an arbitrary Kripke frame to be isomorphic to certain well-known bi-dimensional structures. (shrink)

Philosophers of science have argued that epistemic diversity is an asset for the production of scientific knowledge, guarding against the effects of biases, among other advantages. The growing privatization of scientific research, on the contrary, has raised important concerns for philosophers of science, especially with respect to the growing sources of biases in research that it seems to promote. Recently, Holman and Bruner ( 2017 ) have shown, using a modified version of Zollman ( 2010 ) social network model, that (...) an industrial selection bias can emerge in a scientific community, without corrupting any individual scientist, if the community is epistemically diverse. In this paper, we examine the strength of industrial selection using a reinforcement learning model, which simulates the process of industrial decision-making when allocating funding to scientific projects. Contrary to Holman and Bruner’s model, in which the probability of success of the agents when performing an action is given a priori, in our model the industry learns about the success rate of individual scientists and updates the probability of success on each round. The results of our simulations show that even without previous knowledge of the probability of success of an individual scientist, the industry is still able to disrupt scientific consensus. In fact, the more epistemically diverse the scientific community, the easier it is for the industry to move scientific consensus to the opposite conclusion. Interestingly, our model also shows that having a random funding agent seems to effectively counteract industrial selection bias. Accordingly, we consider the random allocation of funding for research projects as a strategy to counteract industrial selection bias, avoiding commercial exploitation of epistemically diverse communities.

Philosophy of logic is a fundamental part of philosophical study, and one which is increasingly recognized as being immensely important in relation to many issues in metaphysics, metametaphysics, epistemology, philosophy of mathematics, and philosophy of language. This textbook provides a comprehensive and accessible introduction to topics including the objectivity of logical inference rules and its relevance in discussions of epistemological relativism, the revived interest in logical pluralism, the question of logic's metaphysical neutrality, and the demarcation between logic and mathematics. Chapters (...) in the book cover the state of the art in contemporary philosophy of logic, and allow students to understand the philosophical relevance of these debates without having to contend with complex technical arguments. This will be a major new resource for students working on logic, as well as for readers seeking a better understanding of philosophy of logic in its wider context. (shrink)

Background: Mental fatigue can impact physical demands and tactical behavior in sport-related contexts. Small-sided games are often used to develop a specific sport-related context. However, the effects of mental fatigue on physical demands and tactical behaviors during soccer SSGs have not been aggregated for systematical assessment.Objective: This systematic review was conducted to compare the effects of mental fatigue vs. control conditions in terms of the total running distance and tactical behavior of soccer players during SSGs.Methods: The data sources utilized were (...) PubMed, PsycINFO, Scielo, Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were established based on PICOS: Population: healthy youth and young adult men soccer players with regular training practice and belonging to teams with regular competitions; Intervention: exposed to mental fatigue-induced protocols only before SSGs; Comparator: control conditions before SSGs; Outcomes: physical demands and tactical behavior ; Study design: counterbalanced cross-over design; and only full-text and original articles written in English.Results: The database search initially identified 111 titles. From those, six articles were eligible for the systematic review and meta-analysis. Results showed no significant effect of fatigue on total running distance and tactical behavior.Conclusions: A non-significant effect of mental fatigue on total running distance and tactical behaviors performed by soccer players during SSGs was found in this systematic review.

Según Julián Marías, fue Ortega, en 1914, quien hizo el primer uso filosófico de la palabra griega _alétheia_ con el significado de descubrimiento o iluminación: se trata de una innovación significativa porque Ortega introdujo una acepción nueva, sirviéndose de esa palabra, para superar la idea, que le parecía inaceptable, de que la verdad tenga que ser adecuación. Después de Ortega, los demás filósofos, a partir de 1927 con Heidegger, no saben de dónde procede la interpretación etimológica que ellos dan como (...) obvia para sus reflexiones filosóficas sobre la verdad. En realidad no hay textos griegos claros que interpreten el concepto de _alétheia_ ni etimológica ni filosóficamente. Julián Marías descubrió la más antigua discusión etimológica en el lingüista y filósofo Teichmüller (1879), de la cual se sirvió Ortega en fecha tan temprana como 1914 para hacer la primera interpretación filosófica de esa palabra. A pesar de ello, se ha hecho general la creencia de que fue Heidegger el primero que trató sobre la verdad como _alétheia_ en contraposición a lo que denomina _concepto tradicional de la verdad._.

Tanto Tomás de Aquino como Husserl coinciden, respecto a la teoría sobre la verdad, en pensar que (debido a la adecuación) el intelecto hace una copia exacta (absoluta) de una cosa siempre idéntica (igualmente absoluta), y que gracias a ello refutan el relativismo. Pero Julián Marías, entusiasta de la verdad, critica al absolutismo y al relativismo, y piensa que ambos están basados en la verdad como adecuación. La visión que sobre la verdad tiene Marías es consecuencia de su respeto a (...) la realidad, organizada en perspectiva: esta es de la realidad, no del hombre que la mira. Por ello ninguna verdad agota la realidad. Los partidarios de la adecuación suelen aplicar su esquema mental a los objetos irreales o ideales, suponiendo que la realidad como tal, caótica para ellos por la multitud de puntos de vista diferentes, está desorganizada y es fuente de relativismo.

Enrique Gonzalez Fernández estudia en este libro el pensamiento y la obra de Julián Marías (1914-2005), desde la admiración y el conocimiento personal del filósofo católico que compaginó la fe y la razón. La vida y la obra de Marías estuvieron siempre orientadas hacia Dios, y nunca se desanimó en su empeño por construir una filosofía más apta para hacer inteligible la revelación cristiana. De ahí el calificativo de «apóstol de la divina razón». Ante las realidades de la filosofía (...) y del cristianismo, Marías hace una considerable innovación intelectual desde «la perspectiva religiosa en el estudio de los problemas, sin abandonarla en un solo momento». Como católico responsable y, por tanto, innovador, él cree «que es precisamente esa perspectiva religiosa la que permite ver en serio la conexión entre ambas realidades, la que abre el horizonte para una manera nueva, y rigurosamente filosófica, de hacer filosofía». Con prólogo de Harold Raley, profesor especialista en la obra de Julián Marías, el libro se completa con una amplia bibliografía. (shrink)

Según la liturgia, mi vida, es decir, la de cada cual, en su realidad concreta, no es «cosa» alguna, sino proyecto, empresa, misión; acontece, se va haciendo. La tradicional perspectiva cris-tiana reclama una intensificación del conocimiento, relativamente descuidado, de lo que significa ser persona. Un peso del pensamiento helénico, ajeno al cristianismo, ha orientado al pensamiento poste-rior, filosófico y también teológico, a un «sustancialismo» que ha lle-vado a reducir la persona a un tipo muy particular de «cosa».

The study of the contrast between fundamental aspects of spatial and temporal awareness offers a good opportunity to bring to light the relation between philosophical and scientific theories of consciousness. In this paper we critically examine important work by Rick Grush on spatial and temporal experience, and we show that while there is a valid claim for the relevant neuroscientific model to be one that supports Gareth Evans's stance on "behavioral space", there is not at present any scientific model that (...) offers comparable support for philosophical theories of temporal experience, despite some claims by Grush that might suggest the contrary. Moreover, we argue that careful attention to the spatial case allows us to locate the point at which even relatively successful cases of neuroscientific modeling and explanation are left wanting when their aim is to show that phenomenal features of experience are a function of the representational structures produced by our neural information-processing machinery: an aim widely shared by the predominant programmatic stance in current neuroscience research.

Banking firms are becoming increasingly aware that their clients’ management of environmental and social risks may in term threaten their own business as lenders and investors. In addition, stakeholders are requiring banks to improve their social performance. As a result, some banks are developing corporate social responsibility (CSR) policies and management systems to reduce potential risks and improve their performance. In the Spanish financial system, half of the banking firms are savings banks, most of which have always used some Corporate (...) Social Responsibility (CSR) criteria in their management. Private Banks have only recently started to integrate social aspects in their performance. However, no formal analysis has been carried out on the impact of CSR strategies. Various initiatives have been launched nationally and internationally to include the social dimension in management systems. The purpose of this research is to analyse the social performance of the main Spanish financial companies through public data such as social or sustainability reports and media sources. In order to do this, we need to determine which CSR criteria most greatly affect banking firms and to choose the most accurate quantitative and qualitative indicators to measure social performance.

Research on salesperson creativity remains as one of the most under-researched topics in the sales literature despite the evidence that encouraging creativity in the sales domain is a source of competitive advantage. This paper aims to fill this research gap by exploring the influence of perceived ethical climate on salesperson creative performance, paying special attention to the role that emotions play in this process. Data provided by 176 supervisor–salesperson dyads confirm that the trust/responsibility dimension of an ethical climate is positively (...) related to salesperson creative selling by increasing salespeople's organizational pride. Similarly, the perception of unethical selling practices negatively affects salesperson organizational pride, reducing the expression of creative behaviors. Moreover, the negative effect of unethical selling practices on creative performance is stronger (more negative) when salespeople's identification with an organization increases. Managerial implications and future research directions are also addressed. (shrink)

Abstract:In view of Kramer’s theory about paranoid cognition, this paper examines how exaggerated distrustand such cognition produce important negative effects upon social reality. The first section dealswith Searle’s theory of social reality, and how it is basically explained in terms of one world ofphysical particles and groups of intentional agents performing “we” actions. The aim of this sectionis to show that the “we” actions of collective intentionality allow fundamental social practices,namely, those related to institutions. Looking at trust, cooperation, and collective (...) intentionality, thesecond section examines in what sense these three elements form the triad of human civilization.Finally, the last section analyses which negative effects exaggerated distrust and Kramer’s paranoidcognition have upon the Searlean social reality: both, which break off cooperative relations andsolemn pacts, end up disrupting the triad.Keywords: trust; distrust; cooperation; collective intentionality; paranoide cognition.

Feminist reflections on the sexual division of labour have given rise to a body of knowledge on the ethics of care from different disciplines, including philosophy, in which outstanding contributions to the topic have been formulated. This approach is applicable to the analysis of any phenomenon and particularly that of disasters. As various investigations have highlighted, the consequences on the population throughout all of a disaster’s phases (prevention, emergency, and reconstruction) require an analysis of differentiated vulnerabilities based on gender and (...) other identity categories, such as social class, ethnicity, age, disability, sexual identity, etc. The interrelation between all these variables gives rise to differentiated impacts that cannot be ignored in catastrophic contexts, where survival and sustaining life are at stake, so care becomes a central issue. Research on the topic has also identified that, along with the analysis of social vulnerability, we must consider the capacity for agency, both individual and collective, where care is once again of vital importance. Considering the gender approach and its multiple intersections is thus a fundamental theoretical-practical proposal for the study of disasters from philosophy, as it implies an unavoidable epistemic, ontological, and ethical reflection in the face of risk reduction.

The aim of the research was to know the perception of high-level volleyball players of the changes produced in the efficiency of the training process, after a match analysis intervention program based on the Constraint-led Approach. The sample consisted of 11 players from a women's volleyball team. The protocol of the intervention program consisted of providing objective, contextualised and systematic information to the coach that would allow understanding the different real game contexts. We used semi-structured interviews to assess players' perceptions. (...) The athletes perceived changes in training, both in their preparation and development, specifically in greater involvement and organisation in preparing the training; in an increase in the specificity and suitability of training tasks according to individual needs; in the representativeness of the restrictions of the game; in a more tactical approach; in the variability of task and in the accountability to achieve the objective proposed. In addition, in the preparation and development for competition, the players detected more game planning; a deeper analysis of the opponents; an objective selection of the most relevant data, an increase in the depth of match analysis and the inclusion of the weekly meeting with the use of video compared to the previous season. These results expose the benefits of coaches incorporate programmes to obtain objective information about the game in their training process. (shrink)

In Scotland, residents have fought open-net salmon farms and their toll on human and nonhuman bodies for decades. This paper recollects seven years of work in Skye and Raasay, two islands off the northwest coast of the country, developing strategies to divest away from salmon aquaculture. Addressing the contemporary wave of underwater clearances created by UK’s top food export industry, it unpacks the implementation of a transition into alternative horizons by embracing the legacies of toxicity inherited from salmon extractivist industries. (...) CLIMAVORE, a framework developed as a research-led artistic practice by the authors, investigates how to eat in the new seasons of the climate crisis. In a season of marine dead zones, it facilitates new approaches to aquaecology and coastal care that cultivate coastal livelihoods. CLIMAVORE began with a new public forum, shaped as a multispecies intertidal table, established in Skye in 2017 to envision environmentally regenerative and socially reparative forms of food production based on metabolic interactions between humans and depleted landscapes that benefit a plethora of species. CLIMAVORE’s site responsive methodology relies on a socially-engaged art practice, consisting of fieldwork, interviews, working groups, oral histories, performative meals, cooking and building apprenticeships, tidal gardening, material testing and public art installations. Ongoing collaboration with residents, scientists, and policymakers critically explores ways of living not only on but with the coast. This new holistic approach to coastal nourishment provides methodologies for ecological praxis as well as a platform for researchers and the general public to imagine an alternative ecological future: the tidal commons.

Number processing abilities are important for academic and personal development. The course of initial specialization of ventral occipito-temporal cortex sensitivity to visual number processing is crucial for the acquisition of numeric and arithmetic skills. We examined the visual N1, the electrophysiological correlate of vOTC activation across five time points in kindergarten, middle and end of first grade, second grade, and fifth grade. A combination of cross-sectional and longitudinal EEG data of a total of 62 children at varying familial risk for (...) dyslexia were available to form groups of 23, 22, 27, 27, and 42 participants for each of the five time points. The children performed a target detection task which included visual presentation of single digits, false fonts, and letters to derive measures for coarse and fine digit sensitive processing across development. The N1 amplitude analyses indicated coarse and fine sensitivity characterized by a stronger N1 to digits than false fonts across all five time points, and stronger N1 to digits than letters at all but the second time point. In addition, lower arithmetic skills were associated with stronger coarse N1 digit sensitivity over the left hemisphere in second grade, possibly reflecting allocation of more attentional resources or stronger reliance on the verbal system in children with poorer arithmetic skills. To summarize, our results show persistent visual N1 sensitivity to digits that is already present early on in pre-school and remains stable until fifth grade. This pattern of digit sensitivity development clearly differs from the relatively sharp rise and fall of the visual N1 sensitivity to words or letters between kindergarten and middle of elementary school and suggests unique developmental trajectories for visual processing of written characters that are relevant to numeracy and literacy.

The present study had two main aims: to determine whether deaf children show higher rates of key behaviors of ADHD and of Conduct Disorder—CD— than hearing children, also examining whether the frequency of these behaviors in deaf children varied based on cochlear implant use, type of school and level of receptive vocabulary; and to determine whether any behavioral differences between deaf and hearing children could be explained by deficits in inhibitory control. We measured behaviors associated with ADHD and CD in (...) 34 deaf and hearing children aged 9–10 years old, using the revised Spanish version of the Conners scale. We then assessed inhibitory control ability using a computerized Stroop task and a short version of the Attention Network Test for children. To obtain a measure of the level of receptive vocabulary of the deaf children we used a Spanish version of the Carolina Picture Vocabulary Test for Deaf and hearing-impaired children. Deaf children showed significantly higher rates of behaviors associated with ADHD and CD, and over 85% of cases detected with high risk of ADHD-inattentive type in the entire present sample were deaf children. Further, in the group of deaf children a negative correlation was found between receptive vocabulary and frequency of disruptive, aggressive, or antisocial behaviors associated with CD. However, inhibitory control scores did not differ between deaf and hearing children. Our results suggested that the ADHD-related behaviors seen in deaf children were not associated with a deficit in inhibitory control, at least in the interference suppression subcomponent. An alternative explanation could be that these behaviors are reflecting an adaptive strategy that permits deaf children to access information from their environment which is not available to them via audition.

Achieving a comfortable thermal situation within buildings with an efficient use of energy remains still an open challenge for most buildings. In this regard, IoT and KDD processes may be combined to address these problems, even though data analysts may feel overwhelmed by heterogeneity and volume of the data to be considered. Data analysts could benefit from an application assistant that supports them throughout the KDD process and aids them to discover which are the relevant variables for the matter at (...) hand, or informing about relationships among relevant data. In this article, the EEPSA ontology which supports such an assistant is presented. The ontology is developed on the basis that a proper axiomatization shapes the set of admitted models better, and therefore, establishes the ground for a better interoperability. On the contrary, underspecification facilitates the admission of non-isomorphic models to represent the same state which hampers interoperability. This ontology is developed on top of three ODPs which include proper axioms in order to improve precedent proposals to represent features of interest and their respective qualities, as well as observations and actuations, the sensors and actuators that generate them, and the procedures used. Moreover, the ontology introduces six domain ontology modules integrated with the ODPs in such a manner that a methodical customization is facilitated. (shrink)

The aim of this paper is to provide a theoretical and formal framework to understand how the proprioceptive and kinesthetic system learns about body position and possibilities for movement in ongoing action and interaction. Whereas most weak embodiment accounts of proprioception focus on positionalist descriptions or on its role as a source of parameters for internal motor control, we argue that these aspects are insufficient to understand how proprioception is integrated into an active organized system in continuous and dynamic interaction (...) with the environment. Our strong embodiment thesis is that one of the main theoretical principles to understand proprioception, as a perceptual experience within concrete situations, is the coupling with kinesthesia and its relational constitution—self, ecological, and social. In our view, these aspects are underdeveloped in current accounts, and an enactive sensorimotor theory enriched with phenomenological descriptions may provide an alternative path toward explaining this skilled experience. Following O'Regan and Noë sensorimotor contingencies conceptualization, we introduce three distinct notions of proprioceptive kinesthetic-sensorimotor contingencies, which we describe conceptually and formally considering three varieties of perceptual experience in action: PK-SMCs-self, PK-SMCs-self-environment, and PK-SMC-self-other. As a proof of concept of our proposal, we developed a minimal PK model to discuss these elements in detail and show their explanatory value as important guides to understand the proprioceptive/kinesthetic system. Finally, we also highlight that there is an opportunity to develop enactive sensorimotor theory in new directions, creating a bridge between the varieties of experiences of oneself and learning skills.

There is no doubt that the use of Internet for purchasing products and services has constituted a crucial change in how people go about buying them. In the era of digital transformation, the possibility of accessing information provided by other users about their personal experiences has taken on more weight in the selection and buying processes. On these lines, traditional word-of-mouth has given way to electronic word-of-mouth, which constitutes a major social change. This behavior is particularly relevant in the services (...) area, where potential users cannot in advance assess what is on offer. There is an abundant literature analyzing the effects of eWOM on different variables of interest in this sector. However, little is known about the factors that determine eWOM. Thus, the main objective of the present paper is to analyze the impact of two variables on eWOM. Both of them are crucial for potential customers in the process of finding hotel accommodations and they can motivate people to make such comments. The results demonstrate that these variables truly have a significant impact on whether or not users make comments on line. Moreover, it proved possible to observe certain differences according to the profile of the tourist involved and the destination where the hotel is located. In the current changing environment, this information is of great use for hotel managers in order to design strategies according to the type of guest they wish to attract. (shrink)

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

El presente trabajo analiza el libro Santa María del Circo (1998) de David Toscana para establecer la relación entre el espacio y la inversión o indecibilidad de papeles, jerarquías y roles sexuales. Santa María del Circo puede considerarse un entre-lugar de acuerdo con Olalla Castro o un intersticio o un lugar liminal en consonancia con Homi K. Bhabha. Este no-espacio se convierte en un territorio donde se transgrede lo que Roland Barthes llamó sentido común y permite la expansión de los (...) bordes de la cultura. Identificaremos las estrategias de inversión, banalización y trivialización que rompen con los bordes de la cultura o el sentido común, pues lo que ajusta y especifica las conductas sociales se trastoca al grado de invertirse o entrar en contradicción para generar una sociedad dinámica que expande los bordes y acepta nuevas visiones del mundo.
