El objetivo de este estudio es analizar las investigaciones de pregrado en Literatura de una universidad peruana. Se realizó el mapeo sistemático de diez trabajos publicados entre el 2017 y 2022. Los resultados evidencian preferencia por la investigación en literatura peruana y que el género literario más estudiado es el narrativo. Se concluye que en los trabajos no se describen claramente los métodos científicos ni las metodologías de análisis literario; debido a su diversidad, a que los estudios literarios poseen una (...) complejidad interdisciplinaria, y porque los esfuerzos educativos universitarios en investigación se centran en los últimos semestres.

One of the most tantalizing questions about the interpretation of Quantum Theory is the objective vs. subjective meaning of quantum states. Here, by focusing on a typical EPR experiment upon which a selection procedure is performed on one side, we will confront the fully epistemic view of quantum states with its results. Our statement is that such a view cannot be considered complete, although the opposite attitude would also pose well-known problems of interpretation.

We give a common mathematical characterization of relevant stochastic evolution schemes built up in the literatute to attack the quantum measurement problem. This characterization is based on two hypotheses, namely, (i) the trace conservation with probability one and (ii) the existence of a complex phase determining a linear support for the stochastic process driving the random evolution.

The traditional “realist” conception of physics, according to which human concepts, laws and theories can grasp the essence of a reality in our absence , seems incompatible with quantum formalism and it most fruitful interpretation. The proof rests on the violation by quantum mechanical formalism of some fundamental principles of the classical ontology. We discuss if the conception behind Einstein’s idea of a reality in our absence, could be still maintained and at which price. We conclude that quantum mechanical formalism (...) is not formulated on those terms, leaving for a separated paper the discussion about the terms in which it could be formulated and the onto-epistemological implications it might have.

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

Resumen Este trabajo, de carácter exploratorio, descriptivo e interpretativo, estudia las actividades de imagen presentes en un conjunto de cartas electorales enviadas por los principales partidos políticos españoles a los ciudadanos de ese país entre 2004 y 2019; concretamente, las cartas electorales relativas a las elecciones al Parlamento Europeo celebradas en 2004, 2009, 2014 y 2019. Las cartas electorales constituyen una parte del discurso político escrito en las que el candidato a unas elecciones se dirige a los potenciales votantes con (...) un discurso persuasivo, orientado a conseguir su voto. En este contexto, las actividades que se llevan a cabo son principalmente de autoimagen, si bien es posible encontrar también actividades de cortesía y críticas hacia otros partidos políticos -u otros actores sociales-que se enmarcan en una descortesía muchas veces carente de identificación del sujeto concreto al que se dirige y que, en ese sentido, entendemos como despersonalizada. Este trabajo pone de manifiesto tales actividades, mediante el análisis y comparación de estas cartas, no solo de manera sincrónica sino también, cuando es posible, de manera diacrónica. Creemos que todavía no hay ningún trabajo que haya analizado este tipo de textos desde la perspectiva aquí planteada, por lo que consideramos que es un estudio que, además de original, puede abrir camino a otros investigadores que deseen realizar análisis similares o con los que establecer comparaciones.

Delusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of (...) beads of 60:40 and 80:20, considered, respectively, as the “difficult” and “easy” variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients’ deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning. (shrink)

Derrida’s thought is a dynamic dimension, a movement beyond any attempt of conclusive definition. However, is there any possibility to grasp this task of endless destabilization? This paper brings up the proposal of reading Derrida’s work from the close but at the same time aporetical relation between place and space. In this sense, we question the common understanding of space as uniform and empty continuum where place would be just a ‘limit’, a perimeter. In order to do so, we will (...) pay attention to the particular Topology that ‘translation’ illustrates in Derrida’s work, just as the reality of the spectre and mourning, stating these two dimensions as examples of Derrida’s strategy. In this sense, through translation and mourning, we manage to make out that Derrida’s work, even though cannot be summarized in a single object or idea, it might be understood as the endless question about the place of and for deconstruction, that is, about place as deconstruction of space. Thus, Derrida’s Topology may constitute a new and radical way to read not only his own work, but to question ourselves. (shrink)

We argue for an account of chemical reactivities as chancy propensities, in accordance with the ‘complex nexus of chance’ defended by one of us in the past (Suárez, 2017, 2020). Reactivities are typically quantified as proportions, and an expression such as “A + B → C” does not entail that under the right conditions some amounts of A and B react to give the amount of C that theoretically would correspond to the stoichiometry of the reaction. Instead, what is produced (...) is a fraction α < 1 of this theoretical amount, and the corresponding percentage is usually known as the yield, which expresses the relative preponderance of its reaction. This is then routinely tested in a laboratory against the observed actual yields for the different reactions. Thus, on our account, reactivities ambiguously refer to three quantities at once. They first refer to the underlying propensities effectively acting in the reaction mechanisms, and which in ‘chemical chemistry’ (Schummer, 1998) are commonly represented by means of Lewis structures. Besides, reactivities represent the probabilities that these propensities give rise to, for any amount of the reactants to combine as prescribed. This last notion is hence best understood as a single case chance and corresponds to a theoretical stoichiometric yield. Finally, reactivities represent the actual yields observed in experimental runs, which account for and provide the requisite evidence for / against both the mechanisms and single case chances ascribed.

Objective: This study aimed to compare the effects of two intervention programs, high-intensity interval training and moderate-intensity training, on anxiety, depression, stress, and resilience during the confinement caused by the coronavirus disease 2019 in healthy adults.Methods: A total of 67 adults who participated were randomly assigned to two groups: HIIT and MIT groups. The MIT group had to perform a home-based intervention based on aerobic exercises, whereas the HIIT group had to perform a home-based intervention based on HIIT exercises. The (...) two groups had to complete the same physical exercise volume, 40 min per session during the confinement period. Depression, anxiety, stress, and resilience were assessed before and after the intervention.Results: Results showed that HIIT and MIT significantly reduced the stress, anxiety, and depression as well as increase the resilience. Moreover, the improvements obtained in the HIIT group seem to be greater than those of the MIT group in depression.Conclusions: HIIT and MIT decreased anxiety, stress, and depression as well as increased resilience during the COVID-19 confinement. In addition, the HIIT intervention seemed to be more beneficial to reduce depression than the MIT intervention. (shrink)

I put forward an inferentialist account of Lewis structures (LSs). In this view, the role of LSs is not to realistically depict molecules, but instead to allow surrogate reasoning and inference in chemistry. I also show that the usage of LSs is a central part of a person’s identity as a chemist, as it is defined within educational identity theory. Taking these conclusions together, I argue that the inferentialist approach to LSs and chemistry identity theory can be studied in parallel, (...) as two complementary sides of the same research programme.

Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I argue that radical constructivism poses a series of deep methodological constraints on educational research. We focus on the work of Ulrich et al. to illustrate the practical implications of these constraints.

La deconstrucción es la apertura al porvenir, hacia el otro como porvenir absoluto. Sin embargo, ese otro se encuentra ante nosotros y tras nosotros, es un pasado por venir, un pasado que nunca ha sido presente. De este modo, la obra de Derrida puede ser leída como la preocupación constante por esa memoria del porvenir, por la herencia y el duelo, por la apertura al acontecimiento. En este sentido, la memoria en Derrida no puede comprenderse como «reunión en el pensamiento», (...) como «Versammlung» y, por tanto, supone quizás una distancia radical en la obra de Derrida con respecto al pensamiento heideggeriano.

En la recensión se presenta la obra de Byung-Chul Han, quien a través de una serie de comparaciones entre el budismo Zen y la filosofía moderna occidental pretende señalar la riqueza del pensamiento oriental y las posibilidades que brinda al desarrollo de la filosofía contemporánea.

Este texto plantea la posibilidad de realizar una aproximación entre la angustia heideggeriana y la angustia lacaniana. De este modo, se comprueba cómo ambos autores comprenden la angustia como el estado esencial y propio del hombre. Tanto Heidegger como Lacan presentan la angustia como el estado en el que lo imposible, lo que no puede ser representado como objeto, se manifiesta en su esencia. Así, ambos señalan que el objeto de la angustia es la condición para la aparición de cualquier (...) objeto, es decir, plantean la angustia y aquello que ella presenta como la manifestación de lo real mismo. No obstante, es precisamente desde la angustia donde podemos apreciar la diferencia notable que existe entre ambos autores. (shrink)

En este texto se lleva una lectura de la obra lacaniana a través del estudio de sus figuras topológicas. En este sentido, se afirma que el psicoanálisis lacaniano no hace uso de la topología como si no de una herramienta externa si tratase, es decir, como un modo a través del cual obtener ejemplos ilustrativos y explicaciones, sino que el propio pensamiento lacaniano es en sí mismo topológico y, por tanto, no puede ser comprendido al margen de esta dimensión que (...) atraviesa la totalidad de su recorrido. Para ello se estudiarán seis figuras: el grafo del deseo, la cinta de Moebius, el toro, la botella de Klein, la esfera provista de un cross-cap y el nudoborromeo. (shrink)

En este texto se estudia la tensa relación entre lugar y espacio en el “segundo” Heidegger, tomando textos posteriores a Sein und Zeit. Se comprende el espacio como espaciar, concebido desde lo abierto y por lo tanto desde el Claro como des-ocultamiento de la verdad en el lugar. De este modo, el lugar del desocultamiento se define como la obra de arte, como “poema”. Así, se sugiere que el lugar constituye una dimensión del lenguaje y por lo tanto el espacio (...) es el hacer espacio para el habitar de los hombres, si bien el lugar como espacio del lenguaje resulta ser un lugar imposible.

La cuestión de la traducción, como afirma Derrida, es «la» cuestión de la deconstrucción. En este sentido, comprende Derrida que la traducción no consiste en la «transferencia» de significantes entre las lenguas, proceso que respetaría los significados ideales-inmateriales. Por el contrario, Derrida apunta hacia una traducción de un «original» que nunca ha sido, un texto que necesita esencialmente de la traducción y, por tanto, afirma la traducción como una tarea «im-posible», como la continua creación del otro y de lo otro, (...) como recepción de la herencia e imposible afirmación del duelo. En este sentido, cabría plantear la posibilidad de «traducir» los textos de Derrida hacia el pensamiento heideggeriano, donde también se establecería de manera explícita el rechazo a la noción de traducción en cuanto «intercambio», es decir, como tarea técnica o mecánica, apuntando así hacia la traducción como la verdadera esencia del pensamiento y del lenguaje. No obstante, se comprueba en esta aproximación la im-posibilidad de traducir los textos de Derrida al corpus heideggeriano. (shrink)

In a previous essay we demonstrated that quantum mechanical formalism is incompatible with some necessary principles of the mechanism conception still dominant in the physicist’s community. In this paper we show, based on recent empirical evidence in quantum physics, the inevitability of abandoning the old mechanism conception and to construct a new one in which physical reality is seen as a representation which refers to relations established through operations made by us in a world that we are determining. This change (...) is profound and radical, with immediate consequences on both Ontology and Epistemology. This work is our contribution to try to make more concrete how this new conception of the world might be. (shrink)

We study whether the probabilistic postulate could be derived from basic principles. Through the analysis of the Strong Law of Large Numbers and its formulation in quantum mechanics, we show, contrary to the claim of the many-worlds interpretation defenders and the arguments of some other authors, the impossibility of obtaining the probabilistic postulate by means of the frequency analysis of an ensemble of infinite copies of a single system. It is shown, though, how the standard form of the probability as (...) the square of the scalar product follows from Gleason's theorem. (shrink)

Recensión de la obra de Byung-Chul Han "El aroma del tiempo", donde analiza la visión aceptada de una aceleración del tiempo moderno, a través de autores como Lyotard, Baudrillard o Arendt, señalando que, más que ésta, debe considerarse la pérdida de un fundamento, de un elemento ordenador del tiempo. De este modo, no se padece tanto una aceleración de los tiempos como una ausencia de sentido, de dirección, que posibilite así la experiencia de una duración.

Over the past two decades the growth of the organic sector has been accompanied by a shift away from first party, or peer review, systems of certification and towards third party certification, in which a disinterested party is responsible for the development of organic standards and the verification of producer compliance. This paper explores some of the limitations of the third party certification model and presents the case of Mexico as an example of how an alternative form of participatory certification (...) has emerged. The paper suggests that participatory guarantee systems (PGS) are reflective of the growing “beyond organic” movement, which focuses on reconstructing the local and re-embedding food systems into their socio-ecological contexts. It argues that PGS offers a number of benefits for producers and consumers, particularly in the South, but that it faces a number of challenges as well, such as a lack of formal recognition, social conflicts and dependence on donated resources.

Let ‘semantic relevance’ be the thesis that the wide semantic properties of representational mental states (like beliefs and desires) are causally relevant to behavior. A popular way of arguing for semantic relevance runs as follows: start with a sufficient counterfactual condition for causal or explanatory relevance, and show that wide semantic properties meet it with respect to behavior (e.g., Loewer & Lepore (1987,1989), Rescorla (2014), Yablo (2003)).This paper discusses an in‐principle limitation of this strategy: even the most sophisticated counterfactual criteria (...) systematically misclassify irrelevant properties as relevant when they stand in certain kinds of modal co‐variation or ‘entanglement’ relations to genuinely relevant properties. This entanglement problem, I argue, is more general and more serious than proponents of the counterfactual strategy have recognized: it threatens recent interventionist arguments for semantic relevance, and is not easily solved by appeal to proportionality or naturalness. I end by suggesting that proponents of semantic relevance may need to shift their attention from patterns of counterfactuals to the lawful psychological generalizations that explain them. (shrink)

The use of the journal impact factor (JIF) as a measure for the quality of individual manuscripts and the merits of scientists has faced significant criticism in recent years. We add to the current criticism in arguing that such an application of the JIF in policy and decision making in academia is based on false beliefs and unwarranted inferences. To approach the problem, we use principles of deductive and inductive reasoning to illustrate the fallacies that are inherent to using journal (...) based metrics for evaluating the work of scientists. In doing so, we elaborate that if we judge scientific quality based on the JIF or other journal based metrics we are either guided by invalid or weak arguments or in fact consider our uncertainty about the quality of the work and not the quality itself.

Jean Jacques Rousseau definía como "segundo parto" a la transición que supone la adolescencia, al nacimiento de la nueva identidad tras la crisis. La adolescencia coge siempre desprevenido, comienza y con ella llega un tsunami de cambios y transiciones de cuerpo y mente. Por un lado la imaginación se desborda, la sensibilidad está a flor de piel, se vive con grandes dosis de vitalidad y alegría y con la certeza de que todo es posible; hasta cambiar el mundo. Sin embargo (...) se reconoce también al adolescente por los desarreglos emotivos a los que están expuestos, los sentimientos de angustia, los miedos exagerados al ridículo, la crisis de identidad y la fuerte falta de confianza en sí mismos.

El sacrificio humano es una imagen frecuente en las religiones antiguas, concretamente en la griega, y su estudio ha levantado numerosos enfrentamientos entre corrientes historiográficas distintas. Uno de los casos más sobresalientes es del culto a Zeus en el Monte Liceo, que aquí analizamos. Las fuentes literarias reflejan la creencia de los griegos en estos sacrificios humanos, así que podemos decir que los sacrificios fueron reales porque fueron usados para construir paisaje y, por lo tanto, realidad.

The first European settlements in the new world faced technical issues with the help of the XVI century scientific advances. Besides briefly exposing the scientific and technological situation, this paper explores, with the help of reverse engineering, two singular mechanical wits representative of the technological advances introduced in America to overcome different problems. Firstly, a pump, based on an alternative movement system through crankshafts and pistons used against the continuous flooding suffered in the Ciudad de México valley. Although flooding remained (...) a problem (it was solved in the XX century), hydraulic pumps were essential for continuous soil drainage. Secondly, a port crane for handling cannons, military devices, and construction materials during the Lima fortification in the XVII century. For both cases, reverse engineering, through engineering methods, Computer-Aided Design CAD programs, and additive manufacturing, provides virtual and/or tangible mockups that help to analyze and improve our knowledge about the dimensions, materials, and functions of used (and currently lost) mechanical systems during the American colonization.
