Cognitive science is experiencing a pragmatic turn away from the traditional representation-centered framework toward a view that focuses on understanding cognition as "enactive." This enactive view holds that cognition does not produce models of the world but rather subserves action as it is grounded in sensorimotor skills. In this volume, experts from cognitive science, neuroscience, psychology, robotics, and philosophy of mind assess the foundations and implications of a novel action-oriented view of cognition. Their contributions and supporting experimental evidence show that (...) an enactive approach to cognitive science enables strong conceptual advances, and the chapters explore key concepts for this new model of cognition. The contributors discuss the implications of an enactive approach for cognitive development; action-oriented models of cognitive processing; action-oriented understandings of consciousness and experience; and the accompanying paradigm shifts in the fields of philosophy, brain science, robotics, and psychology.

The Coalition of Immokalee Workers (CIW) has successfully combated modern-day slavery by transforming the ways that over a dozen major brands, including Taco Bell, Subway, and Wal-Mart, manage their supply chains. The CIW’s efforts over more than 20 years have effectively stopped enslavement practices, including abuses such as wage theft and peonage indebtedness. We conducted a field ethnography, interviews, and archival analyses to understand this success. We find that the CIW employs a decentered, egalitarian, and ensemble approach to their multiplicities (...) of alliances by collectively “animating” themselves and their partners through ensemble leadership. This combination of alliances, along with worker-driven monitoring, brings life to the CIW motto “We are all leaders.” Translating this motto into daily practice is how the CIW virtually eradicates enslavement practices in corporate supply chains.

Two populations are subdivided into two categories of individuals (hawks and doves). Individuals fight to have access to a resource which is necessary for their survival. Conflicts occur between individuals belonging to the same population and to different populations. We investigate the long term effects of the conflicts on the stability of the community. The modelis a set of ODE's with four variables corresponding to hawk and dove individuals of the two populations. Two time scales are considered. A fast time (...) scale is used to describe frequent encounters and fightings between individuals trying to monopolize the resource. A slow time scale is used for the demography and the long term effects of encounters. We use aggregation methods in order to reduce this model into a system of two ODE's only for the total densities of the two populations which is found to be a classical Lotka-Volterra competition model. We study different cases of proportions of hawks and doves in both populations on the global coexistence and the mutal exclusion of the two populations. Pure dove tactics in both populations are unstable. In cases of mixed hawk and dove in both populations, there is coexistence. Pure dove or mixed hawk-dove tactics in one population can coexist with pure hawks in the other one when the costs of fightings between hawks are large enough. (shrink)

The tumor suppressor protein p53 is intimately involved in the cellular response to DNA damage, controlling cell cycle arrest, apoptosis and the transcriptional induction of DNA damage inducible genes. A transcriptional target of p53, Gadd45, was recently found to bind to PCNA, a component of DNA replication/repair complexes, thereby implicating Gadd45 in DNA metabolism(1). Using biochemical assays, a role for Gadd45 in excision repair in vitro has been demonstrated(1). Antisense experiments have also indicated an in vivo role for the GADD45 (...) gene in UV‐irradiation survival. These discoveries establish a link between p53 and DNA repair through Gadd45. (shrink)

Le présent texte parcourt quelques-unes des œuvres d’Edgar Morin qui traitent du rapport féminin/masculin et femme/homme soit dans une perspective transdisciplinaire – du point de vue de la sociologie ou de la biologie – soit dans la perspective de la théorie de l’évolution et de la génétique. L’innovation épistémologique constitue le fondement permanent de la réflexion de cet auteur. À cet égard, les notions de dialogique et de boucle récursive sont les instruments fondamentaux de l’analyse morinienne du masculin et du (...) féminin.This text runs some of the works of Edgar Morin discusses the relationship male / female and female / male is in a transdisciplinary perspective - from the point of view of sociology or biology - or from the perspective of the theory of evolution and genetics. Innovation is the epistemological foundation of permanent reflection of the author. In this regard, the concept of dialogical and recursive loop are the basic instruments of analysis morinienne of masculine and feminine. (shrink)

The lysine demethylase KDM5A collaborates with PARP1 and the histone variant macroH2A1.2 to modulate chromatin to promote DNA repair. Indeed, KDM5A engages poly(ADP‐ribose) (PAR) chains at damage sites through a previously uncharacterized coiled‐coil domain, a novel binding mode for PAR interactions. While KDM5A is a well‐known transcriptional regulator, its function in DNA repair is only now emerging. Here we review the molecular mechanisms that regulate this PARP1‐macroH2A1.2‐KDM5A axis in DNA damage and consider the potential involvement of this pathway in transcription (...) regulation and cancer. Using KDM5A as an example, we discuss how multifunctional chromatin proteins transition between several DNA‐based processes, which must be coordinated to protect the integrity of the genome and epigenome. The dysregulation of chromatin and loss of genome integrity that is prevalent in human diseases including cancer may be related and could provide opportunities to target multitasking proteins with these pathways as therapeutic strategies.

In this note we reproduce the book reviews that De Morgan wrote on Boole's and Jevons's first logical works. The most notable property of these documents is the mere fact of their existence and the absence of any reference to them in the specialized literature.

Background: Frailty is a common syndrome among older adults and patients with several comorbidities. Grip strength is a representative parameter of frailty because it is a valid indicator of current and long-term physical conditions in the general population and patients with severe mental illnesses. Physical and cognitive capacities of people with SMIs are usually impaired; however, their relationship with frailty or social functioning have not been studied to date. The current study aimed to determine if GS is a valid predictor (...) of changes in cognitive performance and social functioning in patients with type-2 diabetes mellitus and SMIs. Methods: Assessments of social functioning, cognitive performance, and GS were conducted in 30 outpatients with type 2 diabetes mellitus, 35 with major depressive disorder, 42 with bipolar disorder, 30 with schizophrenia, and 28 healthy controls, twice during 1-year, follow-up period. Descriptive analyses were conducted using a one-way analysis of variance for continuous variables and the chi-squared test for categorical variables. Differences between groups for the motor, cognitive, and social variables at T1 and T2 were assessed using a one-way analysis of covariance, with sex and age as co-variates. To test the predictive capacity of GS at baseline to explain the variance in cognitive performance and social functioning at T2, a linear regression analysis was performed. Results: Predictive relationships were found among GS when implicated with clinical, cognitive, and social variables. These relationships explained changes in cognitive performance after one year of follow-up; the variability percentage was 67.7%, in patients with type-2 diabetes mellitus and 89.1% in patients with schizophrenia. Baseline GS along with other variables, also predicted changes in social functioning in major depressive disorder, bipolar disorder, and schizophrenia, with variability percentages of 67.3, 36, and 59%, respectively. Conclusion: GS combined with other variables significantly predicted changes in cognitive performance and social functioning in people with SMIs or type-2 diabetes mellitus. Interventions aimed to improve the overall physical conditions of patients who have poor GS could be a therapeutic option that confers positive effects on cognitive performance and social functioning.

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)

In seiner Auseinandersetzung mit Eberhard behauptet Kant, Kritizismus sei die eigentliche Apologie von Leibniz. Diese Äußerung darf nicht einfach als sarkastisch abgetan werden. Kant kann dies insofern ernsthaft denken und behaupten, da für ihn die Transzendentalphilosophie die wesentliche philosophische Bedeutung des leibnizschen Gedankens aufhebt, liegt doch schon in Leibniz ein kritizistischer Kern, welcher wiedergewonnen werden kann. Man sieht hier nur einen Aspekt dieser historischen Transformation von Leibniz im kantischen Gedanken, und zwar: die explizite Behauptung Kants, das Konzept der prästabilierten Harmonie (...) werde in der Theorie der reflektierenden Urteilskraft und im Begriff der Zweckmäßigkeit kritisch aufgehoben. Dazu muss man jedoch vorher den Grundzug des kritischen Unterschieds zwischen Kant und der leibniz-wolffschen Philosophie durch eine Diskussion über die Bedeutung des Begriffs des Transzendentalen erläutern.

Diversas evidencias parecen indicar que, durante la comprensión oral, el procesamiento del habla se realiza a partir de la información verbal auditiva y de la información viso-gestual proveniente del interlocutor. En este marco, se evaluó el tiempo y la precisión de respuestas de sujetos oyentes en una tarea de lectura labial con el patrón acústico suprimido. En ella, 25 participantes adultos, sin diagnóstico de patologías lingüísticas o cognitivas ni discapacidad auditiva o visual, debían distinguir si estaban frente a una palabra (...) del español a partir de la visualización de su articulación. Para la tarea se construyeron 240 estímulos, divididos en tres grupos de 80 ‘Palabras’ del español, 80 ‘Pseudopalabras’ del español y 80 ‘No-Palabras’, presentados en forma aleatoria. Los resultados respecto del tiempo de respuesta indicaron que las ‘Palabras’ (m=717,6ms) se reconocen con una velocidad menor que las ‘Pseudopalabras’ (m=809,5ms) y las ‘No-Palabras’ (7633,7ms); mientras que las ‘Pseudopalabras’ demoraron más en ser respondidas que las ‘No-Palabras’. Por su parte, en los resultados de precisión los estímulos presentaron el siguiente patrón de reconocimiento: ‘Palabras’<‘Pseudopalabras’<‘No-Palabras’ (correspondientes a un 59,89%, 62,5% y 86,3%, respectivamente). Del mismo modo, se encontró evidencia robusta de la relación entre el tipo de estímulo presentado y el acierto/desacierto de las respuestas, aunque el modelo indica que la condición ‘No-Palabra’ es reconocida con mayor facilidad y que la diferencia entre ‘Palabras’ y las ‘Pseudopalabras’ no es relevante. Asimismo, se observó una relación entre la menor velocidad y el desacierto en las respuestas. Estos datos corroboran la hipótesis de la integración de información proveniente de la percepción visual y el procesamiento del lenguaje, al mismo tiempo que permiten proyectar trabajos futuros con evidencias electrofisiológicas.

Academic entrepreneurship and the formation of spin-offs from educational institutions have been consolidated as essential elements to promote innovation and stimulate economic growth worldwide. However, the evolution of these initiatives shows marked differences between developed countries and emerging economies, such as Colombia. This study focuses on analyzing how research in this area has progressed, identifying the key factors that determine the success of spin-offs and suggesting a framework for action for Colombia in comparison with international dynamics. The findings reveal a (...) shift in research attention from prioritizing the creation of spin-offs to a greater focus on their long-term performance and sustainability. At the international level, the relevance of technology transfer, strategic alliances between universities and industry and the efficient management of technological resources are highlighted. On the other hand, in the Colombian context, research tends to focus on institutional aspects, cultural factors and support regulations, underestimating the analysis of the performance of spin-offs after their creation. This paper aims to contribute to the formulation of policies and strategies that promote not only the emergence but also the sustainability of academic spin-offs in Colombia, seeking to align their practices with international standards in order to maximize their impact on the economic and social development of the country.

Situados en un progresivo traspaso de responsabilidades en la ejecución de los servicios sociales desde el Estado hacia actores no gubernamentales, aparece una demanda hacia el mismo Estado, el cual en lugar de simplemente declinar su labor, debiera de hecho expandir su regulación de modo de asegurar que la oferta social sea eficiente en satisfacer al ciudadano usuario en aquellos servicios prometidos por las políticas y programas sociales. Así mismo, la institucionalidad pública debiera reconocer las demandas del mundo privado para (...) actuar articuladamente hacia fines comunes, que finalmente conduzcan a un horizonte de desarrollo de una sociedad más igualitaria. Este estudio da cuenta de las tensiones, reveladas por autoridades de servicios públicos que atienden personas vulnerables, en su relación de colaboración con OSFL (Organizaciones Sin Fines de Lucro), para alcanzar tal horizonte.

La vigilancia tecnológica, que comienza como un mecanismo empresarial de captación y fidelización clientelar, ha conocido un desarrollo tecnológico tal que, junto a la obtención masiva de datos producidos de forma inconsciente y su tratamiento por la inteligencia artificial, ha permitido la anticipación de las tendencias y la supervisión constante de los deseos e intereses de los usuarios. La integración de vigilancia y consumo ha supuesto que esta lógica del mercado pueda ser entregada a la gubernamentalidad, transformando la racionalidad disciplinaria (...) estática en múltiples dinámicas de observación de una población móvil pero controlable en términos biopolíticos, de modo que el deseo y la libertad se convierten así en dimensiones activas de una economía política actual. Se ofrecen algunos ejemplos de este auténtico panoptismo digital, como puede comprobarse con el uso de navegadores, las aplicaciones financieras, la hipersegmentación de nichos de consumo o el internet de las cosas. Por último, se analiza el tránsito de esta vigilancia hacia una lógica de gobierno basada en la predeterminación de los intereses: es el paso del panoptismo a la gubernamentalidad. (shrink)

Este texto se centra en la génesis de las ciencias sociales a través de una reflexión analítico- descriptiva sobre la sistematización de la ciencia. La ciencia es una creación del ser humano y constituye la mejor herramienta para adquirir conocimientos acerca de su entorno, de sí mismo, del universo... Debe ser interdisciplinaria y para dar soporte a este empeño, hemos tenido que elegir, y hemos optado por comparar la sociología con la filosofía buscando aportaciones (implícitas o explícitas) de prestigiosos pensadores.

Does the board of directors influence cost of debt financing? This study of a sample of Spanish listed companies during the period 2004-2007 provides some evidence about the question. The results suggest that two board attributes - director ownership and board activity - appear to influence in the risk assessment of debtholders because of their ability to reduce agency cost and information asymmetry. We also find a non-linear relationship between board size and cost of debt, suggesting that from certain levels (...) the benefits of large boards may be outweighed by the cost of poorer communication and increased decision-making time.

The purpose of this article is to expose, comment on and analyse the procedures of scientific research and the experimental techniques in the biomedical sciences of the 17th century, with Francesco Redi as the main figure of this study. Specifically, we would like to show how the path through which experimentation takes place in the field of biomedical sciences is not necessarily animated by the physical-mathematical spirit that would supposedly characterise the trite category of «Scientific Revolution», without it being prejudice (...) for the use of precise scientific methods and the obtaining of highly effective experimental results.

El impacto generado por Vigilar y castigar no ha dejado de crecer desde su aparición en 1975. En este artículo se abordan las estrategias de investigación que subyacen a su análisis de la prisión, la cual pasó en poco tiempo de ser un elemento marginal de la penalidad a constituir la forma privilegiada de castigo. La hipótesis de Foucault es que su rápida aceptación por parte del sistema jurídico se debe a la generalización previa de las disciplinas esparcidas por todo (...) el cuerpo social. El problema estriba en que una hipótesis como esta, pese a su evidente originalidad, alberga sin embargo un defecto constitutivo en el análisis propuesto, al no explicitar las precondiciones que hicieron posible dicho proceso. El propósito del artículo es identificarlas en el análisis de Marx en torno a la acumulación originaria. De esa manera, destacamos los elementos de agregación y complementación, así como las posibles disputas entre ambos autores, logrando postular cómo se enmarca la microfísica del poder en la generalización de la forma mercancía y el dominio del capital.

This study examines personal and emotional metaphors of prospective economics teachers about the roles they themselves as teachers and their pupils would play by analysing their drawings and responses to open questions. This is a longitudinal study that analyses the evolution of future instructors using two periods: before and after their teaching practicum. Metaphors are categorised into four classes: behaviourist/transmissive, cognitivist/constructivist, situative/socio-historical, and self-referential. The categories for emotions are primary or social and positive, negative, or neutral. The results show that (...) the highest percentage of metaphors for the teacher’s role in both questionnaires were cognitivist/constructivist. Comparison of the findings before and after the teaching practicum revealed no changes in most of the participants’ metaphors and associated models. The analysis also reveals that among those who change, the tendency is to evolve towards more pupil-centred metaphors and associated models. The most common pupil metaphors are behaviourist and cognitivist, increasing after the practicum. Finally, most of the emotions expressed are positive and social, also increasing after the practicum.
