In the present study, we have demonstrated hysteresis phenomena in the excitability of single, enzymatically dissociated guinea pig ventricular myocytes. Membrane potentials were recorded with patch pipettes in the whole-cell current clamp configuration. Repetitive stimulation with depolarizing current pulses of constant cycle length and duration but varying strength led to predictable excitation (1:l) and non-excitation (1:0) patterns depending on current strength. In addition, transition between patterns depended on the direction of current intensity change and stable hysteresis loops were obtained in (...) stimulus:response pattern vs. current intensity plots in 14 cells. Increase of pulse duration and decrease of stimulation rate contributed to a reduction in hysteresis loop areas. Changes in amplitude and shape of the subthreshold responses during the transitions from one stable pattern to the other, suggested that activity led to an increase in membrane resistance, particularly in the voltage domain between resting potential, and threshold. Therefore, we modelled the dynamic behaviour of the single cells as a function of diastolic membrane resistance, using previously published analytical solutions. Numerical iteration of the analytical model equations closely reproduced the experimental hysteresis loops in both qualitative and quantitative ways. In particular, the effect of stimulation frequency on the model was similar to the experimental findings. The overall study suggests that the excitability pattern of guinea pig ventricular myocytes accounts for hysteresis and bistabilities when current intensity is allowed to fluctuate around threshold levels.

‘Plant neurobiology’ has emerged in recent years as a multidisciplinary endeavor carried out mainly by steady collaboration within the plant sciences. The field proposes a particular approach to the study of plant intelligence by putting forward an integrated view of plant signaling and adaptive behavior. Its objective is to account for the way plants perceive and act in a purposeful manner. But it is not only the plant sciences that constitute plant neurobiology. Resources from philosophy and cognitive science are central (...) to such an interdisciplinary project, if plant neurobiology is to maintain its target well-focused. This manifesto outlines a road map for the establishment and development of a new subject—the Philosophy of Plant Neurobiology—, a new field of research emerging at the intersection of the philosophy of cognitive science and plant neurobiology. The discipline is herewith presented, introducing challenges and novel lines of engagement with the empirical investigation, and providing an explanatory framework and guiding principles that will hopefully ease the integration of research on the quest for plant intelligence.

Philosophers and cognitive scientists reassess systematicity in the post-connectionist era, offering perspectives from ecological psychology, embodied and distributed cognition, enactivism, and other methodologies.

: Accidents will survive the outbreak of driverless cars, but their moral implications will suffer substantial changes. The decision made today by a human in a fraction of a second will eventually be replaced by an algorithm subject to moral scrutiny. This not only raises the question of how the algorithm should work, or whether alternatives solutions are indeed comparable, but also changes the essence of the problem: from ascertaining liability to defining desired outcomes. In this paper, I first contest (...) two possible approaches to resolving the driverless car dilemma – which I call statistical and nominal – to conclude that neither is morally sound. I then propose an alternative solution based on “time-relative equality”, or always sparing younger people. This follows from seeking an egalitarian solution, that is the least intrusive – a position I defend from a possible ageist critique. Keywords: Driverless Cars; Accident; Algorithm; Age-relative Equality Condotti verso un incidente morale Riassunto: Vi saranno incidenti anche dopo la diffusione delle auto a guida autonoma, ma le loro implicazioni morali subiranno mutamenti sostanziali. Le decisioni prese oggi in una frazione di secondo dagli esseri umani saranno alla fine sostituite da un algoritmo soggetto a controllo morale. Sorge non solo il problema di come dovrebbe funzionare questo algoritmo – o se vi siano soluzioni alternative comparabili –, ma cambia anche la sostanza del problema: dall’accertamento dell’imputabilità alla definizione dell’esito auspicato. In questo lavoro discuterò due possibili approcci per risolvere il dilemma – che chiamerò “statistico” e “nominale” –, per concluderne che non sono moralmente corretti. Proporrò quindi una soluzione alternativa, basata sulla “eguaglianza tempo-relativa”, il principio per cui bisogna sempre salvare il più giovane. Questo segue dal cercare una soluzione egalitarista, che sia la meno intrusiva – una posizione che difenderò da una possibile critica che la vede come discriminatoria verso gli anziani. Parole chiave: Automobili a guida automatica; Incidenti; Algoritmo; Eguaglianza relativa all’età. (shrink)

Introduction The act of caring in nursing requires previous deliberation and decision, however this perception only arises when an ethical problem emerges. Objective: Identify ethical problems of nurses action in the area of beginning of human life Method: Exploratory and descriptive method, with a qualitative approach. Semi-structured interviews were used to collect data, who were submitted to content analysis. The sample was constituted by 26 nurses. Results 18 categories of problem areas and 56 ethical problems in early human life were (...) identified. The results obtained are very diverse, including areas such as termination of pregnancy, informed consent or maintaining privacy. However, other problem areas also emerge and numerous new subcategories/ethical problems, including: dealing with miscarriage, extreme situations, minors’ pregnancy, serious malformations detected at birth, consent regarding care during childbirth, Non- identification of a ethical problem, nurse social recognition and non-involvement of the person in labour. Conclusion Nurses face different ethical problems that impact their lives. We intend to contribute in helping to make decisions in this field, which the outset is of hope and joy, but which hides, behind this evidence, countless situations of suffering for everyone involved. The identification of ethical problems in this field, it is the first step to reflect about theme and helping decision-making for nurses that are taking care in this area of beginning of human life, when confronted whit the same type of ethical problems.

Reseña del libro de Miguel Catalán González: La creación burlada. Seudología IV.

La Promoción y Educación para la Salud desarrollada desde los Centros educativos Es-pañoles es una de las herramientas clave de las intervenciones en salud. Por un lado, el acceso a la población infantil y juvenil es casi total debido a la obligatoriedad de la educación. Por otro lado, en esta época de la vida las personas se hallan más receptivas para el aprendizaje, siendo la época del desarrollo vital en la que se adquieren los principales hábitos de vida que se (...) consolidarán con los años (actividad física, alimentación, etc.). Además se trata de un ámbito de intervención social que cuenta con agentes de salud que disponen de alta calificación desde el punto de vista pedagógico: el profesorado, ya sea en el nivel de educación Infantil, como en Primaria y Secundaria. En este marco, el principal objetivo de la Educación para la salud, es desarrollar actividades e incentivar al alumnado para conseguir el mayor grado posible de salud, mediante la adquisición de conocimientos y habilidades que favorezcan la elección y adopción de estilos de vida saludables; buscando la participación, la interacción y la integración social, y trabajando la capacidad crítica y creativa, así como la búsqueda de soluciones. Los Centros escolares, junto con el hogar, son dos de los lugares clave donde tiene lugar el desarrollo individual y social de las personas en sus estadios más tempranos, ejerciendo un importante papel en la configuración de la conducta y los valores sociales de la infancia, la adoles-cencia y la juventud.

O artigo objetiva discutir alguns problemas avançados em determinação social do pensamento a partir das contribuições deixadas por J. Chasin tendo em vista a profícua fundamentação em Marx e Lukács. Tais problemas selecionados são apresentados assumindo como fio condutor as possibilidades da pesquisa científica de objetos ideológicos.

According to F. Adams [this journal, vol. 68, 2018] cognition cannot be realized in plants or bacteria. In his view, plants and bacteria respond to the here-and-now in a hardwired, inflexible manner, and are therefore incapable of cognitive activity. This article takes issue with the pursuit of plant cognition from the perspective of an empirically informed philosophy of plant neurobiology. As we argue, empirical evidence shows, contra Adams, that plant behavior is in many ways analogous to animal behavior. This renders (...) plants suitable to be described as cognitive agents in a non-metaphorical way. Sections two to four review the arguments offered by Adams in light of scientific evidence on plant adaptive behavior, decision-making, anticipation, as well as learning and memory. Section five introduces the ‘phyto-nervous’ system of plants. To conclude, section six resituates the quest for plant cognition into a broader approach in cognitive science, as represented by enactive and ecological schools of thought. Overall, we aim to motivate the idea that plants may be considered genuine cognitive agents. Our hope is to help propel public awareness and discussion of plant intelligence once appropriately stripped of anthropocentric preconceptions of the sort that Adams' position appears to exemplify.

En este trabajo se presenta una interpretación sobre la célebre distinción entre el intelecto activo y el intelecto pasivo en _De anima_ III, 5, a partir de “otra modesta propuesta”. Para ello, se expone el núcleo fundamental de esa reciente propuesta, que identifica el intelecto activo con el hábito de los principios y con el contenido de los primeros principios. A continuación, se ponen de manifiesto algunas objeciones a dicha interpretación y, finalmente, se analizan las notas o características del intelecto (...) activo presentes en el texto de Aristóteles. El propósito de este artículo consiste en mostrar una posible comprensión del intelecto activo de Aristóteles, con la intención de que se convierta en una “aún más modesta propuesta”. (shrink)

An asymmetry between the demands at the computational and algorithmic levels of description furnishes the illusion that the abstract profile at the computational level can be multiply realized, and that something is actually being shared at the algorithmic one. A disembodied rendering of the situation lays the stress upon the different ways in which an algorithm can be implemented. However, from an embodied approach, things look rather different. The relevant pairing, I shall argue, is not between implementation and algorithm, but (...) rather between algorithm and computation. The autonomy of psychology is a result of the failure to appreciate this point. (shrink)

This article first presents the aristotelian criticism of the conception of God as Esse ipsum subsistens in Thomas Aquinas, through one of the most important aristotelian philosophers today, Enrico Berti. Then the answer offered by the thomist Stephen L. Brock in his defense of the ipsum esse is set forth, with reference to the recent disputes regarding this issue in the so-called «analytical thomism». The aim is to determine the status of the recent debate between aristotelians and thomists regarding the (...) question of God as Esse ipsum subsistens, in order to ascertain whether the historical incompatibility between the two metaphysical conceptions is to be considered definitive.

It remains at best controversial to claim, non-figuratively, that plants are cognitive agents. At the same time, it is taken as trivially true that many animals are cognitive agents, arguably through an implicit or explicit appeal to natural science. Yet, any given definition of cognition implicates at least some further processes, such as perception, action, memory, and learning, which must be observed either behaviorally, psychologically, neuronally, or otherwise physiologically. Crucially, however, for such observations to be intelligible, they must be counted (...) as evidence for some model. These models in turn point to homologies of physiology and behavior that facilitate the attribution of cognition to some non-human animals. But, if one is dealing with a model of animal cognition, it is tautological that only animals can provide evidence, and absurd to claim that plants can. The more substantive claim that, given a general model of cognition, only animals but not plants can provide evidence, must be evaluated on its merits. As evidence mounts that plants meet established criteria of cognition, from physiology to behavior, they continue to be denied entry into the cognitive club. We trace this exclusionary tendency back to Aristotle, and attempt to counter it by drawing on the philosophy of modelling and a range of findings from plant science. Our argument illustrates how a difference in degree between plant and animals is typically mistaken for a difference in kind. (shrink)

One can read the history of kitsch and the history of kitsch theories by accentuating either everyday aesthetics (knickknacks) or pseudo art/bad art. The authors have divided their introduction to the topic by accentuating first everyday aesthetics (this part includes a detailed history of kitsch research) and then art—especially the wave of contemporary art that has lately been knocking on the doors of kitsch. Three historical stages of kitsch are discussed. The first stage discusses the topic and gives (e.g., bad, (...) sentimental art and interior design) negative attention only. This phase ends with Clement Greenberg’s essay “Avant-Garde and Kitsch” (1939). The second wave discusses kitsch in a curious manner, mainly around the 1960s. And the contemporary stage of the discussion is often positive (starting from the 1990s). In the part where contemporary art is analyzed, art’s kitschy side is traced historically to the Dutch art market of the seventeenth century. But today’s art world, which is strongly invaded by kitsch, gains the main attention. How did kitsch become so central to contemporary art? What forms has it taken there? (shrink)

In this short epilogue, Barragán and Ryynänen discuss the possibility of using kitsch and kitsch theories horizons for interpreting contemporaneity in various ways. The main spearhead of the critical notes is aimed at academic culture, which Barragán and Ryynänen claim to have become “kitschified” in a sense.

Este artículo analiza los aspectos metodológicos principales del proyecto heideggeriano de una ontología fundamental. Heidegger considera que no hay un punto de partida privilegiado, porque todos estamos hermenéuticamente situados. Por ello propone que la investigación filosófica comience justo donde ya nos encontramos. Esto significa que debemos apropiarnos de nuestra situación hermenéutica. La explicación de esta idea mostrará la clave metodológica de la ontología heideggeriana: la indicación formal. Ella habilita un acceso al fenómeno sin abandonar el marco de la facticidad.

El neo-pragmatismo teorizado por el que puede ser considerado como el pensador más leído e influyente de nuestro tiempo, Richard Rorty, presagia una cultura nueva en relación con la filosofía. El pensador americano se sitúa en el debate abierto, tolerante y flexible de toda la humanidad, negando que haya criterios absolutos, metafísicos, en los que basar la actividad humana. El criterio de justificación y elección entre diversas posturas o visiones del mundo vendrá determinado por los intereses de los miembros y (...) no por correspondencia con la realidad, la naturaleza humana o cualquier principio ahistórico. Sin embargo, la tolerancia, la aceptación del pluralismo, la asimilación de nuevos vocabularios y metáforas… asumen un absoluto, un elemento totalitario, a saber: la contingencia. Aunque pudieran parecer la negación de toda metafísica, las tesis rortyanas albergan y encubren una teoría o metafísica extremadamente fuerte y simple: no hay nada necesario, todo es contingente.

Resumen: La construcción de una ciencia del Trabajo Social constituye un debate que ha adquirido intensidad disciplinar en la última década. Ello es resultado de los esfuerzos progresivos de vigilancia y depuración epistemológica que se ha venido produciendo allí dónde el Trabajo Social tiene presencia. Para contribuir a dicho proceso, este artículo propone un vértice analítico organizado en tres momentos. El primero de ellos se adentra en cuestiones epistémicas mostrando las construcciones internas que el Trabajo Social ha venido discutiendo con (...) relación a la naturaleza del conocimiento que produce. El segundo momento incide asuntos relativos al poder y en las relaciones asimétricas interdisciplinares que experimenta el Trabajo Social en las Ciencias Sociales. El tercero introduce la necesidad de atender la feminización del sujeto constructor de la disciplina como parte de su identidad epistémica secular. Se concluye que la autonomía como disciplina científica depende de las comunidades epistémicas que conviven en Trabajo Social puedan hacer explícitos sus debates que rescaten saberes ausentes, olvidados, postergados y subalternos en las jerarquías de la sociedad de conocimiento, tanto por cadenas internas como por condicionantes externos que limitan la consolidación del ethos disciplinar.: The aim of the article is to analyse a long-standing challenge in the field of social work related to its historical struggle to be taken seriously as a scientific discipline. The paper identifies a tripartite conceptual framework to guide the discussion of the science of social work. The first part describes debates in contemporary social work about the nature of knowledge, considering that social work has experienced researchers who bring critically important perspectives to bear in national and international venues. The second part focuses on the social work’s subordinate academic status within the social sciences and its historical positioning as an applied rather than research-oriented discipline and the impacts relating its power and interdisciplinary asymmetric relations experienced in social work. Finally, the article raises questions about the anonymity of women in the profession’s history. In that sense, expertise in care, social help and service to the other, are feminized components of the socio-professional identity of social work and a crucial issue to consider in understanding the discipline’s standing among other social sciences. The article argues there is evidence of a large variety of positions within the history of social work concerning issues of scientific production within the field. (shrink)

Niniejsza wypowiedź jest próbą ukazania wyższości intelektualnej jednostki wybitnej nad jednostkami przeciętnymi. Transgresja jest tutaj formą przejścia, przemiany artysty, negującego zastany porządek świata, pragnącego podłożyć podwaliny pod nową rzeczywistość widzianą oczami szalonego geniusza - Friedricha Nietzschego, do którego często się odwołuję. Jego pojęcie \"Nadczłowieka\" jest tożsame z pojęciem genialnego twórcy, jednostki wybitnej, niezrozumiałej przez pospólstwo, która swoimi horyzontami twórczymi wybiega daleko poza własną epokę\".

El pensador norteamericano Richard Rorty sostiene que uno de los deseos de la tradición filosófica occidental ha sido el deseo de la Verdad. Esta premisa asume que la filosofía que arranca con Platón ha establecido las bases para una teoría filosófica de la verdad como correspondencia entre pensamiento y realidad. Como alternativa a la interpretación histórica de Rorty sobre la Verdad, se presenta la noción �clásica� de verdad que forjaron Platón y Aristóteles. Con este análisis se pretende poner de relieve (...) las características del intelecto humano en su relación con la realidad, para distinguir el discurso verdadero del falso. (shrink)

The mechanism underlying action potentials is routinely used to explicate the mechanistic model of explanation in the philosophy of science. However, characterisations of action potentials often fixate on neurons, mentioning plant cells in passing or ignoring them entirely. The plant sciences are also prone to neglecting non-neuronal action potentials and their role in plant biology. This oversight is significant because plant action potentials bear instructive similarities to those generated by neurons. This paper helps correct the imbalance in representations of action (...) potentials by offering an overview of the mechanism for plant action potentials and highlighting their similarity to those in neurons. Furthermore, it affirms the role of plant action potentials in discovering the evolution and function of mechanisms of action potentials more broadly. We stress the potential of plants for producing generalisations about action potentials and the possible role of plants as experimental organisms. (shrink)

This study investigates the relationship between the usage of artificial intelligence (AI), specifically AI-based personalized recommendations (AI-PR), and its impact on consumers’ green product awareness (GPA) during online shopping. Recognizing that AI’s influence alone may not significantly affect green buying behaviours, we introduce emotional intelligence (EI) as a moderator to better understand human impact when using AI. The research framework is built upon the Interactive Recommendation Agents and the SOBC framework. A self-administered survey was conducted with 403 respondents, and the (...) data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The findings reveal that AI and AI-PR positively impact GPA, with partial mediation observed among the variables. Furthermore, emotional intelligence positively moderates the relationship between perceived AI usage and GPA. Specifically, individuals with higher emotional intelligence exhibit a stronger positive association between AI usage and GPA. Conversely, emotional intelligence negatively moderates the relationship between AI-based personalized recommendations and GPA, indicating that higher EI weakens the relationship between AI-PR and GPA, while lower EI strengthens it. The implications of this study are significant for marketers and retailers aiming to utilize AI-based personalized recommendations to encourage green behaviour and contribute to a sustainable future. These insights can help them understand the complex dynamics between AI, emotional intelligence, green product awareness, and behavioural intentions. (shrink)

La violencia de género (VG) es consecuencia de la cultura androcéntrica que define las identidades y los roles de hombres y mujeres. Esta construcción socio-cultural establece la desigualdad como un factor limitante y de control para las mujeres, y a partir de ella desarrolla mecanismos para alcanzar sus objetivos, entre ellos la violencia. Suestructuralidad se demuestra cuando situaciones como la pandemia tienen un impacto directo sobre ella, y diferente al resto de las violencias interpersonales. Pero también por las estrategias políticas (...) y sociales que niegan su realidad (negacionismo),a pesar de la objetividad de los 60 homicidios de mujeres y los 5 de niños y niñas que se producen de mediacada año. Todo ello indica que para erradicar la VG es necesario ampliar el pacto de Estado para hacerlo contra el “machismo”, es decir, contra la construcción cultural que la integra como parte de la normalidad para luegocuestionar determinados resultados por su gravedad, al tiempo que los explica y justifica a través de mitos y estereotipos.
