Este trabajo esboza una forma de justificar el principio estructurador central de una teoría veritista de la evaluación epistémica, en respuesta a críticas planteadas por Eleonora Cresto a mi defensa del veritismo frente a una serie de objeciones en el sentido de que no es capaz de explicar la naturaleza y el valor del entendimiento. La primera sección presenta el esbozo de justificación del núcleo de una teoría veritista; la segunda responde a críticas más específicas de Cresto. This paper sketches (...) a way to justify the central tenet of a veritistic theory of epistemic evaluation, in response to problems raised by Eleonora Cresto concerning my defense of veritism, against a series of objetions to the effect that veritistic epistemology is uncapable of explaining the nature and value of understanding. The first section presents the sketch of justification of the nucleus of a veritistic theory, the second responds to some of Cresto's more specific criticisms. (shrink)

The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more fact-oriented (...) and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from (...) social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic. (shrink)

El objeto de este artículo es tratar el tema del fin último o felicidad en la ética de Aritótles, y específicamente en la Ética a Nicómaco, pero distinguiéndolo en tres temas que no deben confundirse: el fin de la política como disciplina arquitectónica, el fin de la vida humana buena y la felicidad. Aunque estos dos fines y la felicidad, según Aristóteles, son lo mismo, podría decirse, usando una expresión muy suya, que “su esencia no es lo misma”. El tratamiento (...) separado de estos aspectos puede clarificar más de una confusión u oscuridad, y su articulación, una vez distinguidos, permite ordenar los principales temas generales de la ética aristotélica.

The main claim of this study is that, contrary to Latour’s view about the need to leave aside epistemology to deal with anything valuable about science, Mario Bunge has consistently built up a detailed and thorough epistemology. The argumentative strategy will be to show that (a) it is not true that we have never been modern (b) epistemology is here to stay, and (c) Mario Bunge endorses a strong scientific realism, a brand of materialism, systemism and emergentism, including a moral (...) dimension (there are objective values like, truth, peace and justice that deserve to be respected). Then, Bunge’s realism rejects axiological neutrality making scientists responsible for their actions. Bunge has always been modern and keeps enriching his own views. (shrink)

The aim of this meta-analysis was to evaluate the effects of complex training on sprint, jump, and change of direction ability among soccer players. After an electronic search, 10 peer-reviewed articles were considered in the meta-analysis. The athletes included in this meta-analysis were amateur to professional level male soccer players. These studies incorporated CT in soccer players who were compared to a control group. Significant moderate to large improvements were observed in the CT group [sprint: standard mean difference = 0.92–1.91; (...) jump: SMD = 0.96–1.58; COD: SMD = 0.97–1.49] when compared to control groups. Subgroup analysis were also conducted based on age, duration, and competitive level. The beneficial effects of CT were greater in players <18 vs. ≥18 years, after ≥8 vs. <8 weeks and among professional vs. amateur players. In conclusion, regular soccer training programs may be supplemented with CT to improve sprint, jump, and COD performance. A longer duration of CT seems to be optimal in improving the physical abilities of soccer players. Professional players and <18 years players may benefit more from CT program. (shrink)

We examine the comportment of the global trajectory of a piecewisely conceived single species population growth model. Formulation relies on what we develop as the principle of limiting factors for population growth, adapted from the law of the minimum of Liebig and the law of the tolerance of Shelford. The ensuing paradigm sets natality and mortality rates to express through extreme values of population growth determining factor. Dynamics through time occur over different growth phases. Transition points are interpreted as thresholds (...) of viability, starvation, and intraspecific competition. In this delivery, we focus on the qualitative study of the global trajectory expressed on continuous time and on exploring the feasibility of analytical results against data on populations growing under experimental or natural conditions. All study cases sustained fittings of high reproducibility both at empirical and interpretative slants. Possible phase configurations include regimes with multiple stable equilibria, sigmoidal growth, extinction, or stationarity. Here, we also outline that the associating discrete-time piecewise model composes the logistic map applied over a particular region of the phase configuration. Preliminary exploratory analysis suggests that the logistic map’s chaos onset could surpass once the orbit enters a contiguous phase region. (shrink)

Este artículo sostiene que la exacerbación autoritaria y totalitaria del capitalismo, en la primera mitad del siglo xx, tuvo su origen en la crisis experimentada por el capitalismo de libre mercado, debido a dinámicas propias de la sociedad liberal. El resultado fue una masiva violación de los derechos humanos liberales que habían posibilitado la consolidación y legitimación del propio capitalismo de libre mercado. De esta manera, en el texto se esboza que a la sociedad liberal moderna le es inherente una (...) tendencia autoritaria, vinculada a la dinámica inestable y propensa tendencia a la crisis de la reproducción del capital. Este rasgo estructural es ilustrado con los debates de la Escuela de Frankfurt sobre el fin del capitalismo liberal. Y dentro de este horizonte general, se sigue con especial detalle el análisis crítico que Franz Neumann realiza, en tensión con “la tesis del capitalismo de Estado” de Friedrich Pollock, sobre el devenir totalitario de la República de Weimar.

A lo largo de la historia el ser humano ha sentido interés por el fenómeno del movimiento y su vínculo con la ilusión de vida; diferentes mecanismos y sistemas articulados se han construido con el fin de insuflar vida en seres inertes. El presente artículo reflexiona sobre la cualidad móvil del acto creador presente en diferentes campos socioculturales, desde el misticismo hasta los avances tecnológicos. Se parte del enigma del anima, y su conexión con los creadores, denominados ejecutantes y sus (...) creaciones, denominadas “avatares encarnados”. Se analizan las relaciones de control-libertad, dependencia-independencia entre el ejecutante y su “avatar encarnado”; como también el grado de aceptación que tiene la audiencia al ver las creaciones reproducidas bajo el dispositivo diacrónico. La transición del autómata al personaje animado constata la evolución de los sistemas de representación y reconocimiento del movimiento. (shrink)

The foundations of analysis offered by Cauchy and Riemann were not immediately welcomed by the mathematical community. Before 1870 the foundations of mathematics were considered more or less a national affair. In this paper, Dutch ideas of rigour in analysis between 1840 and 1870 will be discussed. These ideas show that Dutch mathematicians were aware of developments abroad but preferred the concept of infinitesimals as a foundation of mathematics.

Reactive theories of responsibility see moral accountability as grounded on the capacity for feeling reactive-attitudes. I respond to a recent argument gaining ground in this tradition that excludes psychopaths from accountability. The argument relies on what Paul Russell has called the 'subjectivity requirement'. On this view, the capacity to feel and direct reactive-attitudes at oneself is a necessary condition for responsibility. I argue that even if moral attitudes like guilt are impossible for psychopaths to deploy, that psychopaths, especially the "successful" (...) and "secondary" subtypes of psychopathy, can satisfy the subjectivity requirement with regard to shame. I appeal to evidence that embarrassment and shame are grounded on the same affective process and data that psychopathic judgments about embarrassment are neurotypical. If I am right, then psychopaths ought to be open to shame-based forms of accountability including shame punishments. I conclude by considering why psychopaths rarely self-report shame. I argue that lacking a capacity to see oneself as flawed is a different sort of failure than lacking the capacity to feel. (shrink)

The recognition of extracellular molecules by cell surface receptors is the principal mechanism used by cells to sense their environment. Consequently, signals transduced as a result of these interactions make a major contribution to the regulation of cellular phenotype. Historically, particular emphasis has been placed on elucidating the intracellular consequences of growth factor and cytokine binding to cells. In addition to these interactions, however, cells are usually in intimate contact with a further source of complex structural and functional information, namely (...) immobilised extracellular matrix and/or cell surface adhesion proteins. A key question in recent years has been whether cells use the myriad of adhesion protein‐receptor interactions purely for structural and migratory function, or whether these interactions also make a more varied contribution to cell phenotype. Here we review dynamic aspects of the function of one major class of adhesion receptor, the integrins. In particular, we focus on the evidence for shape changes in integrin molecules, the mechanisms responsible for regulating ligand binding, and the signals transduced following integrin occupancy.

Flow describes a state of intense experiential involvement in an activity that is defined in terms of nine dimensions. Despite increased interest in understanding the flow experience of musicians in recent years, knowledge of how characteristics of the musician and of the music performance context affect the flow experience at the dimension level is lacking. In this study, we aimed to investigate how musicians’ general music performance anxiety level and the presence of an audience influence the nine flow dimensions. The (...) participants were 121 university music students who performed solo a music piece once by themselves and once in front of an audience. Their general MPA level was measured with an adapted version of the STAI and ranged from 27 to 76. The level of the nine flow dimensions was assessed with the Flow State Scale-2 after each performance. The levels of “concentration on task at hand,” “sense of control,” and “autotelic experience” decreased significantly with increasing general MPA level. The levels of “unambiguous feedback” and “loss of self-consciousness” decreased significantly with increasing general MPA level during the public performance only. The level of “sense of control” was significantly lower during the public performance than the private performance across participants. The level of “unambiguous feedback” was significantly lower during the public performance than the private performance for participants with a general MPA level higher than 47. The level of “loss of self-consciousness” was significantly lower during the public performance than the private performance for participants with a general MPA level higher than 32. In contrast, the general MPA level and the audience did not significantly affect the levels of “challenge-skill balance,” “clear goals,” and “action-awareness merging.” These results show that the effects of general MPA level and audience vary greatly across flow state dimensions. We conclude that musicians’ flow state should be analyzed at the dimension level rather than as a global score. We discuss how our findings could inform the development and implementation of interventions. (shrink)

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

El trabajo pretende continuar con la pregunta en torno al papel de la democracia y su funcionalidad en la economía de mercado. Lo nuevo a desarrollar bajo este interrogante, es trasladar la reflexión al ámbito del socialismo y específicamente a lo que se ha denominado el socialismo de mercado. La aspiración es presentar los desarrollos teóricos en torno al denominado socialismo de mercado, y cómo desde allí se ha estructurado un concepto de democracia que adquiere validez desde el reconocimiento de (...) las llamadas libertades reales y no solo formales. Este debate nos traslada a un escenario teórico particular, el de los denominados marxistas analíticos, el cual se ha sometido a una amplia discusión tanto desde sus defensores como desde sus detractores. Por esta razón retomo a varios autores relevantes en esta corriente teórica como son: John Roemer, Adam Przeworki y Philippe Van Parijs, con el ánimo de hacer una presentación analítica de la idea de mercado, democracia y socialismo. A modo de consideraciones finales, se pretenden dejar algunos delineamientos críticos, en aras del debate académico, que se han hecho a estas acepciones teóricas, en términos de la equiparación analítica que se hace entre individualismo metodológico y colectivismo metodológico. Igualmente sobre el no-reconocimiento de una neutralidad del mercado; y la validación que se hace de la aplicación de modelos socialdemócratas. (shrink)

Introducción: Los cambios biológicos, sicológicos, económicos y sociales que se observan durante el envejecimiento conllevan a pensar que en los ancianos existe una serie de factores que favorecen la aparición de una depresión. Objetivo: evaluar la efectividad de una intervención sicológica para disminuir la depresión en adultos mayores de la Casa de abuelos "Dr. Diego Tamayo Figueredo", de Puerto Padre, en el período de noviembre de 2013 - mayo de 2014. Material y métodos: se realizó un estudio de intervención sicológica (...) en una muestra de 12 adultos mayores de la casa de abuelos. Se aplicó un programa de intervención sicológica, así como la Escala de Depresión Geriátrica para realizar la valoración antes y después de la intervención. Se empleó el modelo Cognitivo- Conductual de Beck. Los datos fueron tratados según la estadística descriptiva. Resultados: el porciento más elevado de pacientes correspondió al grupo de ancianos con edades entre los 60 y 90 años de edad. Respecto al sexo, el más frecuente es el masculino. El asma bronquial, la hipertensión arterial y la diabetes Mellitus representaron el mayor porciento de antecedentes patológicos personales. Conclusión: la intervención sicológica resultó efectiva pues se logró disminuir a leve los niveles iniciales de depresión establecida y los considerados con leve a no depresión, por lo tanto se afirma que con su aplicación fue modificado el estado emocional de los adultos mayores que se implicaron en la muestra. Introduction: Biological, psychological, financial and social changes observed during aging lead to think that there is a series of factors that favor the appearance of depression in senior citizens. Objective: Assessing the effectiveness of a psychological intervention in order to reduce depression in senior citizens from "Dr. Diego Tamayo Figueredo" Senior Citizens' House, Puerto Padre, from November 2013 to May 2014. Material and methods: A psychological intervention study was conducted on a sample of 12 senior citizens from the house. A psychological intervention program as well as the Geriatrics Depression Scale were applied before and after the intervention in order to make the assessment. The Beck's cognitive-behavior model was used. Data was processed according to descriptive statistics. Results: The highest percentage of patients corresponded to a group of seniors between 60 and 90 years of age. Regarding sex, males are more common. Bronchial asthma, arterial hypertension and diabetes mellitus represented the highest percentage of personal pathological history. Conclusion: The psychological intervention proved to be effective since initial established depression levels were reduced to minor and those considered as minor were reduced to no depression ; therefore, it is stated that its application modified the state of mind of the senior citizens involved in the sample.

Burnout is characterized by emotional exhaustion and caused by exposure to excessive and prolonged stress related to job conditions. Moreover, burnout is highly prevalent among health care professionals. The aim of this study is, first, to examine the mediating role of social support over the effect of burnout in health care professionals and, second, to explore potential gender differences. A convenience sample of 1,035 health professionals from Ecuador, including 608 physicians and 427 nurses, was surveyed using the Maslach Burnout Inventory, (...) Social Support Survey, and General Health Questionnaire as measures of burnout, social support, and general health, respectively. Social support was found to mediate the negative effects of burnout on health regardless of gender. Differences across the three dimensions of burnout and health are further discussed, along with their implications for designing effective burnout interventions for health care professionals in Ecuador.

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

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.

The letter from Arius to Alexander of Alexandria, also known as «Arius’ profession of faith», has been transmitted in its original language, Greek, by Athanasius (De Synodis) and Epiphanius (Panarion). Also, Hilary of Poitiers quotes a Latin translation of the letter twice (De Trinitate IV and VI). The comparative study of the two Greek versions and the Latin translation reveals small textual variants, which points to the independence of the three testimonies. The textual variant (κτιστὴν, instead of κριτὴν) is the (...) most interesting; it comes from a Greek version that has not been preserved. However, our work has been able to reconstruct this lost textual variant using an ancient and forgotten conjecture of Erich Klostermann. (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.

Most growth models for complex networks consider networks comprising a single connected block or island, which contains all the nodes in the network. However, it has been demonstrated that some large complex networks have more than one island, with an island size distribution obeying a power-law function Is~s-α. This paper introduces a growth model that considers the emergence of islands as the network grows. The proposed model addresses the following two features: the probability that a new island is generated decreases (...) as the network grows and new islands are created with a constant probability at any stage of the growth. In the first case, the model produces an island size distribution that decays as a power-law Is~s-α with a fixed exponent α=1 and in-degree distribution that decays as a power-law Qi~i-γ with γ=2. When the second case is considered, the model describes island size and in-degree distributions that decay as a power-law with 2<α<∞ and 2<γ<∞, respectively. (shrink)

El libro tiene su origen en varios encuentros académicos que iniciaron en el 2014 y pasaron por Medellín, Cali y Bogotá; se trata, por tanto, de un primer resultado de un proceso de trabajo colectivo.

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

To what extent do aesthetic taste and our interest in the arts constitute who we are? In this paper, we present a series of empirical findings that suggest an Aesthetic Self Effect supporting the claim that our aesthetic engagements are a central component of our identity. Counterfactual changes in aesthetic preferences, for example, moving from liking classical music to liking pop, are perceived as altering us as a person. The Aesthetic Self Effect is as strong as the impact of moral (...) changes, such as altering political partisanship or religious orientation, and significantly stronger than for other categories of taste, such as food preferences. Using a multidimensional scaling technique to map perceived aesthetic similarities among musical genres, we determined that aesthetic distances between genres correlate highly with the perceived difference in identity. Further studies generalize the Aesthetic Self Effect beyond the musical domain: general changes in visual art preferences, for example from more traditional to abstract art, also elicited a strong Self Effect. Exploring the breadth of this effect we also found an Anaesthetic Self Effect. That is, hypothetical changes from aesthetic indifference to caring about music, art, or beauty are judged to have a significant impact on identity. This effect on identity is stronger for aesthetic fields compared to leisure activities, such as hiking or playing video games. Across our studies, the Anaesthetic Self Effect turns out to be stronger than the Aesthetic Self Effect. Taken together, we found evidence for a link between aesthetics and identity: we are aesthetic selves. When our tastes in music and the arts or our aesthetic interests change we take these to be transformative changes. (shrink)

We propose a semiotic framework to underpin a posthumanist philosophy of education, as contrasted to technological determinism. A recent approach to educational processes as semiotic phenomena lends itself as a philosophy to understand the current interplay between education and technology. This view is aligned with the transhumanist movement to defend techno-scientific progress as fundamental to human development. Particularly, we adopt a semiotic approach to education to tackle certain tensions in current debates on the human. Transhumanism scholars share the optimistic belief (...) that there is no limit to how the ethical use of technology can help alleviate suffering and increase our health and wisdom. From this perspective, it appears possible to acquire capacities that require rethinking the notion of human altogether. For others, this undermining of essentialist concepts of humanity entails serious risks, especially related to ethical egalitarianism. We adopte the perspective of edusemiotics, a framework that brings together semiotics, educational theory and philosophy of education. As a theoretical-practical framework, edusemiotics affords a hermeneutic and semiotic method for our approach. Peirce’s logic of signs is used to analyze socio- educational interactions as environmental. We observe two lines of thought. On the one hand, technological transhumanism enhances Cartesian mind–body dualism. On the other hand, philosophical posthumanism seeks to overcome this dichotomy. The former proposal construes human transformation as an artifactualization derived from techno-scientific enhancements. The latter position proposes an integrative posthumanism, capable not only to include edusemiotic theory but also to rethink the concept of learning as mutual to that of human. (shrink)
