Sharpe’s ratio is the most widely used index for establishing an order of priority for the portfolios to which the investor has access, and the purpose of this investigation is to verify that Sharpe’s ratio allows decisions to be made in investment portfolios considering different financial market conditions. The research is carried out by autoregressive model of the financial series of returns using Sharpe’s ratio for evaluations looking over the priority of financial assets which the investor can access while observing (...) the effects that can cause autocorrelated series in evaluation measures for financial assets. The results presented in this study confirm the hypothesis proposed in which Sharpe’s ratio allows decisions to be made in the selection of investment portfolios under normal conditions thanks to the definition of a robustness function, whose empirical estimation shows an average 73% explanation of the variance in the degradation of the Spearman coefficient for each of the performance measures; however, given the presence of autocorrelation in the financial series of returns, this similarity is broken.

The consideration of racial differences in the biology of disease and treatment options is a hallmark of modern medicine. However, this time-honored medical tradition has no scientific basis, and the premise itself, that is, the existence of biological differences between the commonly known races, is false inasmuch as races are only sociocultural constructions. It is time to rid medical research of the highly damaging exercise of searching for supposed racial differences in the biological manifestations of disease. The practice not only (...) condoned but required by the National Institutes of Health of utilizing racial identification as a demographic characteristic with assumed biological implications is at best badly flawed, and at worst unintentionally contributes to perpetuating the fallacy of natural differences between persons of different skin color, which has been used in the past to advance the cause of racial discrimination.

Open Letter to Comrade Žižek is an attempt to question and highlight some incongruous points that Slavoj Žižek, one of the greatest critics of capitalism and its ideological effects in the contemporary world, expressed in his latest books about the Pandemics. The text focuses in the economic, political, social and cultural consequences of Žižek’s position and goes further in developing another position related to the spread of COVID-19 and the preventive measures to fight it.

En este trabajo se propone una aproximación al uso filosófico del dios griego Dioniso en la obra de Platón, con especial referencia a la vertiente pedagógicopolítica del pensamiento platónico en la República y, sobre todo, en las Leyes. se discuten brevemente los trabajos anteriores que han tratado esta cuestión, incluidos los dos más recientes que versan sobre las Leyes y sobre la faceta filosófica de Dioniso, al hilo de una propuesta de lectura de las presencias y ausencias de Dioniso en (...) Platón a través de tres dimensiones −el simposio, los misterios y la poesía con fines educativos− que convergen en la finalidad política reformista del filósofo ateniense. (shrink)

In the present article, after reviewing the existing bibliography on De uera religione, a study is made of the text of the uera rel. 3, 3, where St. Augustine presents what we have called a Platonic dialogue written by the Doctor of Hippo himself. The dialogue is analysed, presenting first of all the “lectio magistralis” that Augustine puts in Plato’s mouth, pointing out from this discourse the contingency of created beings and their link with the concept of creatio ex nihilo (...) that Augustine himself had already presented some years before in the De Genesi aduersus manicheos. Subsequently, the article highlights the reflection on the human being as a rational entity capable of contemplating the Beauty and Greatness of God, as well as the impediments that may exist for this. Finally, the article exposes what we have called the “myth of the perfect man”, with which St. Augustine, in imitation of Plato himself, closes his dialogue with a myth with which he synthesizes all that he had affirmed up to this point.

The combination of student Self-Regulation (SR) and the context of Regulatory Teaching (RT), each in varying degree, has recently been demonstrated to have effects on achievement emotions, factors and symptoms of stress, and coping strategies. The aim of the present research study is to verify its possible further effects, on academic behavioral confidence and procrastination. A total of 1193 university students completed validated online questionnaires with regard to specific subjects in their degree program. Using an ex post facto design, multivariate (...) analyses and structural equation modeling (SEM) were carried out in order to test the relationships predicted by the model. SR and RT had a significant joint effect in determining the degree of academic behavioral confidence and of procrastination. Academic behavioral confidence also significantly predicted reasons for procrastinating, and these in turn predicted activities of procrastination. Conclusions are discussed, insisting on the combined weight of the two variables in determining academic behavioral confidence, reasons for procrastinating and activities subject to procrastination, in university students. Implications for guidance and educational support of university students and teachers are analyzed. (shrink)

This theoretical analysis seeks to contribute to three objectives within the context of the proposed Frontiers Research Topic: delimit two levels of analysis in the present pandemic situation: medicine-epidemiology and behavioral psychology, still under-addressed. While medicine has its essential role on the biological side, psychology has a comparable role on the behavioral side. Analyze the importance of behavioral-educational factors in the pandemic situation, using a precise theoretical model from educational psychology for this analysis. Propose preventive, psychoeducational intervention strategies based on (...) the previous analyses. (shrink)

Las vanguardias artísticas nacieron insertas en un mundo de cambios para destronar un sistema de órdenes que estaban en decadencia. En los inicios del XX se experimentó la primera gran crisis del canon estético que hasta entonces definía el arte, los vanguardistas lo cuestionaron provocando la ruptura del discurso narrativo tradicional y lo reinventaron hasta convertirlo en uno de los pilares del mundo contemporáneo, abriendo una puerta desde lo imposible a lo posible. Como se verá en este artículo, debido a (...) su sentido crítico, la obra de Nietzsche fue capaz de anticipar las coordenadas generales de las vanguardias con los ejes de su pensamiento: el nihilismo, la dicotomía dionisiaca/apolínea y la voluntad de poder como conceptos clave para comprender su génesis, el proceso de acción artística y su sentido. Para ello se recorrerá su obra en sus distintas etapas, y se interrelacionarán con las vanguardias, especialmente con el dadaísmo y el surrealismo. (shrink)

The aim of this research was to determine the degree to which undergraduate students’ learning approach, academic achievement and satisfaction were determined by the combination of an intrapersonal factor (self-regulation) and a interpersonal factor (contextual or regulatory teaching). The hypothesis proposed that greater combined regulation (internal and external) would be accompanied by more of a deep approach to learning, more satisfaction and higher achievement, while a lower level of combined regulation would determine a surface approach, less satisfaction and lower achievement. (...) Within an ex post facto design by selection, 1036 university students completed validated questionnaires using an online tool. Several multivariate analyses were conducted. Results showed that the combination of self-regulation and external regulation can be ordered as levels along a five-point scale or heuristic. These levels linearly determine type of learning approach, academic achievement and satisfaction. Implications are established for quality and improvement of the teaching and learning process at university. (shrink)

RESUMEN: Este artículo analiza la Regla de Oro de la Humanidad, que es denominador común moral de la mayoría de religiones y culturas. En primer lugar, se estudian los elementos de retribución, reciprocidad y altruismo implicados. En segundo lugar, se desarrollan algunas de las habituales críticas sobre esta Regla y dos argumentos de defensa. Finalmente, se aplica el análisis sobre esta Regla a la resolución de cuatro casos controvertidos. La intención es considerar que la Regla de Oro forma parte de (...) la ética de la alteridad.ABSTRACT: This article analyses the Golden Rule of Humanity, which is the common moral denominator of the majority of religions and cultures. Firstly, it looks at the elements of retribution, reciprocity and altruism as implied. Secondly, it develops some of the common criticisms of this Rule and two arguments of defence. Finally, it applies the analysis of this Rule to the resolution of four controversial cases. The intention is to consider that the Golden Rule belongs to the ethics of alterity.PALABRAS CLAVE: regla de oro, alteridad, identidad, altruismo, reciprocidad, retribución, evaluación intercultural.KEYWORDS: golden rule, alterity, identity, altruism, reciprocity, retribution, intercultural evaluation.

The aim of this research was to establish linear relations (association and prediction) and inferential relations between three constructs at different levels of psychological research –executive dysfunction(microanalysis),self-regulation(molecular level), andself-vs.external regulation(molar level), in the prediction of emotion regulation difficulties. We hypothesized that personal and contextual regulatory factors would be negatively related to levels of executive dysfunction and emotion regulation difficulties; by way of complement, non-regulatory and dysregulatory personal, and contextual factors would be positively related to these same difficulties. To establish relationships, (...) we used a retrospective,ex postfacto design, where 298 university students voluntarily participated by completing standardized self-reports. Linear and structural correlational, predictive analyses were performed, as well as inferential analyses. Results were consistent and validated the proposed hypotheses, for both association and prediction. The most important result refers to the discriminant value of the five-level combination heuristic for predicting Executive Function and External (contextual) Dys-Regulation. In conclusion: (1) both personal and contextual regulation factors must be analyzed in order to better understand the variation in executive functions and emotion regulation difficulties; (2) it is important to continue connecting the different levels of the constructs referring to self-regulation, given their complementary role in the behavioral analysis of regulation difficulties.

Este artículo de homenaje a la Profesora Yolanda Ruano se divide en dos partes. En la primera discuto las críticas que ella realizara a mi libro sobre la diosa Fortuna en las que avanzaba su propio análisis de las complejas relaciones entre razón y fortuna en el pensamiento occidental. En la segunda parte, desde el punto de vista del “giro icónico” en humanidades y ciencias sociales, analizo el caso concreto del auge y desaparición de la diosa Fortuna en la iconografía (...) política de la ciudad de Berlín. A lo largo del siglo XIX la diosa Fortuna desaparece de la escena berlinesa y es sustituida por la diosa Niké o Victoria, que popularmente se interpreta como un Ángel de la Victoria. Este es el marco de la infancia de Walter Benjamin, quien más tarde expresará su visión de la historia con un otro ángel completamente distinto, el Angelus Novus de Paul Klee. (shrink)

La cultura esquimal proporciona multitud de ejemplos que ilustran las teorías científicas del complejo mundo animista y shamánico. De hecho, tradicionalmente los esquimales han sido considerados el paradigma ideal de sociedad animista y shamánica junto a algunas otras poblaciones siberianas. Pese a que en repetidas ocasiones se ha afirmado sin tapujos que es un pueblo sin religión, los esquimales poseen un amplísimo repertorio de rituales, ceremonias y festejos que reflejan a la perfección su profundo sentido religioso. La “fiesta de las (...) vejigas” es uno de esos acontecimientos. Los motivos que conducen a su celebración, así como las consecuencias de no llevarlo a cabo, constituyen los tres pilares básicos de la mentalidad religiosa esquimal: la falta, el castigo y la penitencia.

We are going to analyse the issue of alterity in the philosophy of Miguel de Unamuno through the study of Abel Sánchez. In this nivola, Unamuno examines the concept of envy and establishes the bases of a theory of alterity based on the specular relationship with the other, which it is constituted by the scarcities of the one who looks. We will also look at what are the philosophical premises of this narration, in which way it is linked with the (...) organic philosophy of Unamuno, and what its relationship with the theatre piece El Otro is, released more than a decade after but of a quite similar subject. Finally, we will outline a possible theory of the alterity by Unamuno that it is formulated through the fraternity and altruistic help. (shrink)

The numerical study of a glycolytic model formed by a system of three delay differential equations reveals a multiplicity of stable coexisting states: birhythmicity, trirhythmicity, hard excitation and quasiperiodic with chaotic regimes. For different initial functions in the phase space one may observe the coexistence of two different quasiperiodic motions, the existence of a stable steady state with a stable torus, and the existence of a strange attractor with different stable regimes (chaos with torus, chaos with bursting motion, and chaos (...) with different periodic regimes). For a single range of the control parameter values our system may exhibit different bifurcation diagrams: in one case a Feigenbaum route to chaos coexists with a finite number of successive periodic bifurcations, in other conditions it is possible to observe the coexistence of two quasiperiodicity routes to chaos. These studies were obtained both at constant input flux and under forcing conditions. (shrink)

"Trabajar significaba para mí que la persona, es decir, su valor, no cambiaba, que simplemente caía - por autoconvencimiento o por cualquier otra influencia - en el hechizo de una sugestión duradera y penetrante, que vivía realmente en ella, que quedaba impregnada de ella. Y que después despertaba con la sensación de haber enriquecido su vida con algo oscuro fuera del alcance de toda comprensión" (Musil, Diarios).

The self- vs. external-regulation behavior theory, SR-ER Theory model has postulated the Self-Regulation /Non or De-Regulation/Dys-regulation continuum in the person and in their context. The model also generates a behavioral heuristic that allows us to predict and explain the variability of other dependent behavioral variables in a range of scenarios. Consequently, the objective of this study was to validate the different scales prepared on the basis of the theory presented. A total of 469 students voluntarily completed at different times the (...) five questionnaires presented, to give a total of 1,385 completed questionnaires. Using an ex post facto design, descriptive, correlational, confirmatory factorial analysis, reliability, and concurrent validity analyses were carried out. The scales were analyzed individually and as a whole. The results showed the acceptable structure of scale and consistent levels of reliability. The five levels generated by the SR-NR-DR combinatory heuristic that arises from the theoretical model determined significant differences in the levels of the variables analyzed for each psychological context. We discuss the theoretical implications and the implications for the assessment and improvement of the behaviors analyzed in function of the personal and contextual regulation levels evaluated.

This introduction positions the special issue by highlighting the inherent relationality of place as well as how place is not just an object of analysis but something that shapes thinking, writing and experiences of the world. We reflect on why sociology has found it somewhat more difficult than its social science counterparts to give place the centrality it merits, and discuss whether this reflects a problem with dealing with questions of ‘scale’ and thinking the ‘in-betweenness’ of place. We assess important (...) formulations of place in recent place theories, including non-essentialist framings of place such as ‘progressive’ and as ‘assemblage’. We make a case for seeing the articles in this special issue (and Thesis Eleven’s own long history of publishing writing on the topic of place) as resonating with the themes of place as materiality, atmospheres and spaces of belonging.

The SRL vs. ERL theory has shown that the combination of levels of student self-regulation and regulation from the teaching context produces linear effects on achievement emotions and coping strategies. However, a similar effect on stress factors and symptoms of university students has not yet been demonstrated. The aim of this study was to test this prediction. It was hypothesized that the level of student self-regulation (low/medium/high), in interaction with the level of external regulation from teaching (low/medium/high), would also produce (...) a linear effect on stress factors and symptoms of university students. A total of 527 undergraduate students completed validated questionnaires about self-regulation, regulatory teaching, stress factors and symptoms. Using an ex post facto design by selection, ANOVAs and MANOVAs (3 x 3; 5 x 1; 5 x 2) were carried out. The results confirmed that the level of self-regulation and the level of regulatory teaching jointly determined the level of stress factors and symptoms of university students. Once again, a five-level heuristic of possible combinations was configured to jointly determined university students’ level of academic stress. We concluded that the combination of different levels of student regulation levels and regulation from teaching process jointly determines university students’ level of academic stress. The implications for university students’ emotional health, stress prevention and well-being are established. (shrink)

The purpose of this article is to explore the concept of Philosophy within the works written by Wittgenstein if we take into account the ambivalent sense of the term phármakon. Thus, it will be outlined a contest of paradoxes between, on the one hand, healthiness, sanity, and the adaptable confidence produced by western rationality materialized into objective science, and, on the other hand, sickness, insanity, the world of perplexities, and the realm of desire and death, essential to philosophical thought. Bearing (...) in mind last Wittgenstein’s approaches, we will understand the Tractatus both critical to the deficiencies of western Reason and imprisoned within them. But the “enchanting” power of western Reason, conducting to identify rationality and scientificity in that work, will be conjured in the last Wittgenstein through the opening of plural realms of rationality and of discourses. In this way, philosophical questions will be rescued from silence and absurdity. (shrink)

Vamos a ofrecer un esbozo de la presencia del sueño en la obra literaria y filosófica de Miguel de Unamuno. A partir del comentario de La vida es sueño repasaremos los posibles significados de este concepto en la escritura unamuniana que propone Carlos Blanco Aguinaga en El Unamuno contemplativo. Valoraremos la contradicción que supone entender el sueño como dinamismo lúcido creador de realidades nuevas y a la vez como una ensoñación pasiva sin conciencia de sí. Por último, expondremos qué consecuencias (...) depara esta preferencia por lo soñado en la escritura, y cómo la consideración onírica de la realidad altera la percepción del ser como autoconciencia reflexiva.

In “Science as a Vocation,” Max Weber identifies a trajectory within modernity of increased rationalization, which results in a dangerous loss of meaning, a marginalization of religion, and a disenchanted view of the world. Weber’s misunderstanding of religion as premodern and “magical” results in his underestimating how religion can contribute to “re-enchanting” a field of knowledge, specifically medicine. This article proposes to turn to a theology of the Holy Spirit as “giver of life” for resources to “re-enchant” medicine. Re-enchantment does (...) not require returning to a magical view of the world but retrieving a real sense of God at work in the world, thereby enabling the health care worker and scientist to arrive at a deeper understanding of vocation.

Son modelos que parten de presupuestos distintos y llegan a diferentes conclusiones. Se analiza la noción de racionalidad y razonabilidad de los individuos. Y también, el concepto de egoísmo y la posibilidad del altruismo y el tránsito de la autonomía individual al autogobierno colectivo. Finalmente se propone la teoría de la voluntad y la teoría del interés para llegar a algunas (...) conclusiones. (shrink)

The aim of this research was to delimit the predictive and mediational model of resilience between character strengths to predict flourishing, in a sample of undergraduate students. After signing their informed consent, 642 university students completed three validated scales. Using an ex post facto design, regression, structural modeling, and mediation analyses were carried out, in order to construct a multi-causal predictive model. Results indicated a consistent predictive direct effect of character strengths on resilience and flourishing and of resilience on flourishing. (...) As hypothesized, resilience also showed a mediating effect on the relationship between character strengths and flourishing. Additionally, results also revealed that the reactive and proactive factors of resilience were explained by different character strengths, reinforcing the idea that the two directions are complementary and necessary. Finally, several implications were established for the practice of positive psychology. (shrink)
