The deformation and wear events that underlie microwear and macrowear signals commonly used for dietary reconstruction in fossil animals can be replicated and quantified by controlled laboratory tests on extracted tooth specimens in conjunction with fundamental micromechanics analysis. Key variables governing wear relations include angularity, stiffness (modulus), and size of the contacting particle, along with material properties of enamel. Both axial and sliding contacts can result in the removal of tooth enamel. The degree of removal, characterized by a “wear coefficient,” (...) varies strongly with particle content at the occlusal interface. Conditions leading to a transition from mild to severe wear are discussed. Measurements of wear traces can provide information about contact force and particle shape. The potential utility of the micromechanics methodology as an adjunct for investigating tooth durability and reconstructing diet is explored. (shrink)

There have been two main lines in the literature on restricted games: the first line was started by Myerson (1977) that studied graph-restricted games an the second one was initiated by Faigle (1989). The present paper provides a unified way to look on the literature and establishes connections between the two different lines on restricted games. The strength and advantages of this unified approach becomes clear in the study of the inheritance of the convexity from the game to the restricted (...) game where an interesting result by Nouweland and Borm (1991) on the convexity of graph-restricted games is turned into a direct consequence of the corresponding result by Faigle (1989), by means of this relation.

Basic proteins and nucleic acids are assembled into complexes in a reaction that must be facilitated by nuclear chaperones in order to prevent protein aggregation and formation of non‐specific nucleoprotein complexes. The nucleophosmin/nucleoplasmin (NPM) family of chaperones [NPM1 (nucleophosmin), NPM2 (nucleoplasmin) and NPM3] have diverse functions in the cell and are ubiquitously represented throughout the animal kingdom. The importance of this family in cellular processes such as chromatin remodeling, genome stability, ribosome biogenesis, DNA duplication and transcriptional regulation has led to (...) the rapid growth of information available on their structure and function. The present review covers different aspects related to the structure, evolution and function of the NPM family. Emphasis is placed on the long‐term evolutionary mechanisms leading to the functional diversification of the family members, their role as chaperones (particularly as it pertains to their ability to aid in the reprogramming of chromatin), and the importance of NPM2 as an essential component of the amphibian chromatin remodeling machinery during fertilization and early embryonic development.

Roger Boscovich, belonging to XVIII century, halfway from Newton to Faraday, is traditionally considered as a newtonian philosopher. Nevertheless, following Berkson’s suggestion, he could be a Field Theory forerunner. In this work, we will try to go on with the idea of this suggestion in order to show this possible Boscovich’s contribution.

There is a constructive method to define a structure of simple k -cyclic Post algebra of order p , L p , k , on a given finite field F ( p k ), and conversely. There exists an interpretation Φ 1 of the variety $${\mathcal{V}(L_{p,k})}$$ generated by L p , k into the variety $${\mathcal{V}(F(p^k))}$$ generated by F ( p k ) and an interpretation Φ 2 of $${\mathcal{V}(F(p^k))}$$ into $${\mathcal{V}(L_{p,k})}$$ such that Φ 2 Φ 1 ( B ) (...) = B for every $${B \in \mathcal{V}(L_{p,k})}$$ and Φ 1 Φ 2 ( R ) = R for every $${R \in \mathcal{V}(F(p^k))}$$. In this paper we show how we can solve an algebraic system of equations over an arbitrary cyclic Post algebra of order p, p prime, using the above interpretation, Gröbner bases and algorithms programmed in Maple.

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)

El presente artículo completa la tesis de Arendt-Agamben sobre los refugiados como límites a los derechos humanos. Si este límite se basa en la relación exterior de la nuda vida del refugiado con un Estado, aquí se propone la relación interior de la nuda vida intersexual con un cuerpo mutilado por la biomedicina. Al igual que la persona refugiada, la intersexual pone en cuestión los derechos y el derecho. Se plantean los conceptos cuerpo viviente, precariedad, precaridad y vulnerabilidad como base (...) de una ética del cuidado que produzca otro derecho. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anthropological Perspectives in Psychiatric NosologyJuan J. López-Ibor Jr. (bio) and María-Inés López-Ibor (bio)KeywordsDSM, etiology, Aristotelian causes, social dramasPsychiatry and clinical psychology, as we learn in this paper, are disciplines in need of an ontological perspective. Very few branches of contemporary learning share this characteristic. Probably only theoretical physic and theology—as the rest have long ago given up trying to define and understand the essence of their object, for example, (...) life in the case of biology or mind in psychology. Consequently, the paper by Pérez-Álvarez, Sass and García-Montes, “The Ontology of Mental Disorders in Constructivist Perspective,” (2008) should be welcomed and indeed included in the reading lists for trainees in psychiatry and clinical psychology.The authors propose an approach to the understanding of mental disorders that is extremely attractive and well articulated, and which also has practical implications for clinicians. It is not just another “philosophical divertimento” devoid of scientific and practical importance. Let us analyze the article in an orderly way.Less DsmThe authors of the target paper disapprove of the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III/IV approach to defining illnesses by starting from the symptoms that are present—on the grounds that this may lead clinicians to assume that their sole role is to identify, fight, and suppress the symptoms by whichever procedure. They propose an alternative that is dear to myself because it follows the path of the so-called “anthropological” psychiatry of Binswanger, von Gebsattel, Erwin Strauss, Zutt, López-Ibor, Sr., and others. In essence, this is a phenomenological approach to the meaning of mental diseases, one that emphasizes how the illness is revealed to the patient him- or herself.The target article’s criticism of DSM should be considered in the context of the abuses committed on its behalf. The DSM is not a textbook of psychiatric disorders, nor does it contain a definition of the diseases. The DSM does not tell what a disease is (Klerman et al. 1984)—something that is impossible with a classification system based on the manifestations of the diseases, the signs and symptoms. The DSM, as its title states, is just a diagnostic and statistical manual, which does not contain anything about the origin of [End Page 259] any disease nor an explanation of why it exists or what it means. The DSM is, in fact, just a tool to determine whether a disease is present, and therefore to facilitate communication between professionals and with other individuals, without saying anything about the disease’s aitia—a key term (associated with notions of essence as well as cause) to be discussed below. In theory, most clinicians should understand these limitations; it may be, however, that this is not really the case for many who read or use the DSM. In the world there are around 200,000 psychiatrists; since 1980 the number of DSM copies sold is in the order of several hundred thousand.The misuse of a classification system is even more noticeable in the International Classification of Diseases (ICD)-10 Research Version. The instructions for the use of this version recommend that the first step is to make an inventory of all the symptoms present, and then to construct a diagnosis based on them. This how all computer-assisted systems work. This procedure can, however, only be valid if the clinician has already reached a diagnostic conclusion by other means—a diagnosis then to be confirmed for research purposes. It may be that this is one of the reasons why the ICD-10 Research Version has almost never actually been used for research.Furthermore, the concept of symptoms in psychiatry applies only to organic mental disorders (Schneider 1959), conditions in which the patient’s attitude and way of experiencing the symptoms do not play the kind of role that they play in schizophrenia and other mental disorders. The quotation from the important paper by Sass and Parnas in this context is most appropriate. It is indeed that case that “subjective experience can play an important causal role in the progressive experiential transformations of a developing schizophrenic illness... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Creativity Belongs to the Person, not to DiseaseJuan J. López-Ibor Jr. (bio) and María-Inés López-Ibor (bio)Keywordscreativity, patho-biography, Saint Teresa, visionsIn the paper, “From the Visions of Saint Teresa of Jesus to the Voices of Schizophrenia,” Cangas, Sass, and Pérez-Álvarez (2008) take an original approach to patho-biography that is very welcome.The temptation to designate historical individuals or characters of fiction as suffering from mental disease has always produced disagreeable feelings (...) in me. This sort of abuse of psychiatry and of the people in question is parallel to the abuse by the media or lay citizens when they describe, say, an especially violent murderer as a schizophrenic—forgetting that the vast majority of people with schizophrenia are not in the least violent. Having read Santa Teresa’s writings during my adolescence, well before I even considered entering medicine, I reacted to comments about her alleged psychiatric illnesses with uneasiness, to put it mildly. The Santa Teresa of La Vida de la Santa Madre Teresa de Jesús (her autobiography), of the Camino de Perfección, and of the El Castillo Interior was surely not a mental patient, it seemed to me. The same would apply to San Juan de La Cruz, Jean D’Arc, Don Quijote, Sancho Panza, Edipus, and Clitemnestra, to mention a few. Even van Gogh’s paintings did not seem to me the productions of a patient with schizophrenia or epilepsy. Of course all of them may have suffered, at certain periods of life, symptoms attributable to a mental disorder, but their creativity rested elsewhere, and was often manifest during healthy periods of their lives. After years spent fighting the stigma of mental diseases, and after organizing several exhibitions of works of art of people with mental diseases, we came to the conclusion that creativity and singularity belong to the person, not to the illness. Some of the diseases of these individuals may have being accidents (van Gogh’s hallucinations and psychotic symptoms, for example, were most probably due to intoxications with absinthe, then rich in hallucinogenic alkaloids such as tujone), or, together with other life circumstances, may have had unspecific influences on the person’s condition. In contrast with many other psychiatric disorders that are represented in ancient Greek and Roman literature, there are no descriptions of individuals with schizophrenia in the Greek and Roman literature dating from the fifth century bc to the beginning of the second century Ad (Evans et al. 2003), and several authors have speculated that schizophrenia did not exist before the eighteenth century (Ellard 1987).Caution is important when dealing with mental health and religious issues in contrast with creativity. The creativity of people suffering from bipolar disorders is well recognized (Jamison 1993) and [End Page 277] the same applies to alcohol and drug intoxication. Tellenbach (1986) has also written on the creativity of depressed persons, although he refers more to the disposition of mood (Schwermut) than to clinical depression as such. The link between melancholia and genius put forward by Aristotle has often been misinterpreted. The philosopher was considering the melancholic temperament and not the melancholic illness as we would understand it today. Of the four temperaments, it is in his view only the melancholic that is gifted with creativity. The sanguine person seeks the immediate pleasures of life, the choleric one considers himself powerful and dedicates himself to manifesting this power, and the phlegmatic individual is disconnected from life and seeks to live without effort or pleasure. The melancholic temperament leads to creativity because of the predominance of doubt, reflection, and dissatisfaction with the miseries of life.Freud’s notion of religiosity as a collective obsessive neurosis is totally mistaken, in my view. The three main themes of obsessions are cleanliness, order, and guilt. In none of these cases is the theme the goal of the action; rather, it is a strategy to contain anxiety. As a consequence, patients with obsessions and compulsions about dirt and cleanliness tend to be dirty themselves, because the real purpose of their compulsions is not in fact to be clean but rather to satisfy a ritual. When order... (shrink)

We present PhrasIS, a benchmark dataset composed of natural occurring Phrase pairs with Inference and Similarity annotations for the evaluation of semantic representations. The described dataset fills the gap between word and sentence-level datasets, allowing to evaluate compositional models at a finer granularity than sentences. Contrary to other datasets, the phrase pairs are extracted from naturally occurring text in image captions and news headlines. All the text fragments have been annotated by experts following a rigorous process also described in the (...) manuscript achieving high inter annotator agreement. In this work we analyse the dataset, showing the relation between inference labels and similarity scores. With 10K phrase pairs split in development and test, the dataset is an excellent benchmark for testing meaning representation systems. (shrink)

Nonprofit organizations (NPOs), are quite complex in terms of organizational structure, diversity at the workplace, as well as motivational mechanisms and values rationality. Nevertheless, from an Organizational Psychology perspective, the systematic analysis of this context is scarce in the literature, particularly regarding conflicts. This qualitative study analyzes types, prevalence and consequences of conflicts in a large NPO organization considering as theoretical framework several consolidated Organizational Psychology theories: Conflict Theory, Social Comparison Theory and the Equity Theory. Conflicts were analyzed taking into (...) account volunteers’ perspective, who has been consistently protagonist on NPOs research, but also considering paid staff’s perspective, as one of the main stakeholders in these organizations, whose relative power has increase in the past decade due the professionalization of the NPO’s sector. Results confirmed the existence of four types of conflicts: task, process, status and relationship conflicts. Relationship conflict is the least reported type, revealing the protection factor that values and engagement with a social aim have on this organizational context. The most relevant finding is the strong difference between paid staff and volunteers in conflict perceptions, showing paid staff, overall, higher levels of conflicts than volunteers. Findings also show stronger negative consequences for paid staff compared to volunteers. Theoretical and practical implications are discussed. (shrink)

RESUMENEste trabajo analizará cuáles son las posibles consecuencias que los descubrimientos de la neurociencia pueden tener sobre la reflexión ética en torno al deporte. Siguiendo los trabajos en neuroética de Jonathan Haidt y Joshua Greene, parece ser que nuestro comportamiento moral está basado en una serie de mecanismos automáticos neuronales de carácter emotivo que acontecen en nuestros cerebros. Estos mecanismos podrían ser útiles a la hora de explicar el comportamiento de los hinchas deportivos, sin embargo, convertirían en inútiles los esfuerzos (...) de la ética del deporte por establecer el principio del fair play como regulador ético de la práctica deportiva. Este trabajo ofrecerá dos contra-argumentos que mostrarán que, primero, nuestro comportamiento no está determinado por ciertos mecanismos automáticos que acontecen en el cerebro y, segundo, de hecho, la configuración de nuestro cerebro facilitaría en ciertos casos la posibilidad de que los hinchas desarrollen un comportamiento más ético. Por lo tanto, las metas de la ética del deporte no se ven socavadas completamente por los descubrimientos de las neurociencias.PALABRAS CLAVEÉTICA DEL DEPORTE, NEUROÉTICA, HINCHA DEPORTIVO, JUEGO LIMPIOABSTRACTThis work shall analyze whether or not the recent studies on neuroethics and neighbour disciplines have a critical impact on the ethical reflection on sports. Given Jonathan Haidt’s and Joshua Greene’s works on neuroethics, our moral behaviour seems to be mainly rooted in emotive mechanisms within our brain. If this is true, then sports supporters’ behaviour can easily be explained by appealing to such emotive brain mechanisms. However, they will turn the efforts to apply the moral principle that is supposed to regulate the sporting world—the fair play principle—into useless efforts. I shall give two counter-arguments that will show, firstly, that supporters’ misbehaviour cannot be totally explained by pointing out to several neural—natural—mechanisms, and, secondly, that our brains’ make-up can, nevertheless, make sports supporters more willing to abide by the fair play principle. Therefore, sport ethics’ aims are not undermined by neuroscientific knowledge.KEYWORDSSPORTS ETHICS, NEUROETHICS, SPORTS SUPPORTER, FAIR PLAY PRINCIPLE. (shrink)

Research investigating female gaming is relatively scarce, and past research has demonstrated that men are more likely to be problematic gamers. Few studies have focused on female gamers in community samples, and those that have been published have mainly collected data qualitatively in Europe. There is case study evidence suggesting clinicians are increasingly treating problem female gamers. The aim of this study is threefold: (i) to establish an international female gamer profile, (ii) to determine predictors associated with perceived internet gaming (...) disorder (IGD), and (iii) to identify those who are potentially at risk of developing gaming addiction and its characteristics by applying a quantitative approach. A cross-sectional online survey was applied through international gaming forums recruiting 625 female gamers, assessing sociodemographics, gaming devices used and play genres, and a set of questionnaires on gaming (e.g., problem online gaming [e.g., the nine-item short-form scale to assess IGD: IGDS9-SF], female stereotypes [e.g., sex role stereotyping scale], and psychological symptoms [e.g., Symptom CheckList-27-plus]). Female gamers from all continents reported the use of all videogames, especially popular online games using computers and consoles. The proportion of gamers with potential IGD was one per cent. Regression analyses identified several risk factors for increased scores on the IGDS9-SF, namely having achievement and social motivations, embodied presence and identification with the avatar, hostility and social phobia together with negative body image, playing Multiplayer Online Battle Arena, Massively Multiplayer Online Role-Playing Games, and First-Person-Shooter games. Findings contribute to filling the gap in knowledge on female gaming, to aid in the applicability of problematic gaming measurements in female gamers, especially those who are at risk of problematic gaming. The purpose of this study is to enhance the validity of the current measures to diagnose problem gaming appropriately in both genders. (shrink)

This book is a call to expand and diversify our approach to the study of the human mind in relation to the Theory of Mind. It proposes that it is necessary to combine cross-disciplinary methods to arrive at a more complete understanding of how our minds work. Seeking to expand the discussion surrounding the Theory of Mind beyond the field of psychology, and its focus on our capacity to ascribe mental states to other people, this volume collects evidence and research (...) to point to a more holistic understanding of our own minds, the minds of others, behavior, language, and reasoning. This book therefore illuminates the conceptual intricacy underlying the Theory of Mind. It posits that a wide scope is necessary to make a breakthrough in scientific research towards a full understanding of the nature, function, and development of our capacity to converge on biological processes of the brain towards consciousness, emotion, awareness, and cognition. The volume presents methods, results, critiques, and models intended to provoke debates in various academic disciplines. It is of interest to scholars working in psychology, neuroscience, philosophy of mind, and artificial intelligence. (shrink)

The output from motor neuron pools is influenced by the integration of synaptic inputs originating from descending corticomotor and spinal reflex pathways. In this study, using paired non-invasive brain and peripheral nerve stimulation, we investigated how descending corticomotor pathways influence the physiologic recruitment order of the soleus Hoffmann reflex. Eleven neurologically unimpaired adults completed an assessment of transcranial magnetic stimulation -conditioning of the soleus H-reflex over a range of peripheral nerve stimulation intensities. Unconditioned H-reflex recruitment curves were obtained by delivering (...) PNS pulses to the posterior tibial nerve. Subsequently, TMS-conditioned H-reflex recruitment curves were obtained by pairing PNS with subthreshold TMS at short and long intervals. We evaluated unconditioned and TMS-conditioned H-reflex amplitudes along the ascending limb, peak, and descending limb of the H-reflex recruitment curve. Our results revealed that, for long-interval facilitation, TMS-conditioned H-reflex amplitudes were significantly larger than unconditioned H-reflex amplitudes along the ascending limb and peak of the H-reflex recruitment curve. Additionally, significantly lower PNS intensities were needed to elicit peak H-reflex amplitude for long-interval facilitation compared to unconditioned. These findings suggest that the influence of descending corticomotor pathways, particularly those mediating long-interval facilitation, contribute to changing the recruitment gain of the motor neuron pool, and can inform future methodological protocols for TMS-conditioning of H-reflexes. By characterizing and inducing short-term plasticity in circuitry mediating short- and long-interval TMS-conditioning of H-reflex amplitudes, future studies can investigate supraspinal and spinal circuit contributions to abnormal motor control, as well as develop novel therapeutic targets for neuromodulation.

El objetivo de este artículo es definir la concepción del acto involuntario de Francisco Suárez y mostrarla como un medio que permite comprender y profundizar en su teoría de la acción humana. En esta cuestión, el Doctor Eximio parte de presupuestos elaborados por Tomás de Aquino que amplía y adapta siguiendo sus propias tesis metafísicas y teológicas sobre la relación entre Dios y las creaturas. Mostraremos cómo Suárez vincula el verdadero involuntario con el _simpliciter_, lo forzado, necesario e indeseado, dejando (...) al _secundum quid_ como un acto mixto en el que la libertad y la voluntad, pese a las injerencias externas, no quedan anuladas. Por último, subrayaremos las consecuencias de la definición suareciana de lo involuntario sobre la noción de libertad, haciendo patente que tanto una como otra serían imposibles fuera del marco teórico que él sustenta, caracterizado por la eficiencia humana (y su dependencia de la divinidad) y no por la premoción física.

Background: Monitoring the daily change in resting heart rate variability can provide information regarding training adaptation and recovery status of the autonomic nervous system during training camps. However, it remains unclear whether postural stabilization is essential for valid and reliable ultra-short-term recordings in short-term overseas training camps.Design: Observational and longitudinal study.Purpose: This study aimed to investigate ultra-short-term heart rate variability recordings under stabilization or post-stabilization periods in four overseas training camps.Participant: Twenty-seven U-20 male national team futsal players voluntarily participated in (...) this study.Method: Resting HRV was evaluated for 10 min during the early morning of each training camp. The natural logarithm of the root mean square of successive normal-to-normal interval differences was used for comparisons. Time segments of HRV were divided into two periods with three measures within each: the first 30-s, the first 60-s, and the 5-min standard during stabilization; the first 30-s, the first 60-s, and the 5-min standard after stabilization.Result: The results demonstrated trivial to small ES, very large to nearly perfect ICC, and narrow range of SEM when all time segments of HRVUST were compared to the 1st_5 min and 2nd_5 min HRV. Furthermore, the magnitude of the correlation coefficients ranged from very high to nearly perfect for all the time segments. The HRVUST posted excellent agreement in all time segments with/without postural stabilization. Trivial to small levels of effect size in all time segments of LnRMSSDmean and LnRMSSDcv across overseas training camps was identified.Conclusion: The first 30 or 60-s LnRMSSD recordings can be used to evaluate daily cardiac-autonomic function during overseas training camps in futsal players. The process for stabilization seems to be unnecessary for measuring the morning resting LnRMSSD in overseas training camps among young adult futsal players. (shrink)

There can be no doubt that discrimination based on sex, race, ethnicity, religion or beliefs should not be tolerated in academia. Surprisingly, however, in recent years, policies of Diversity, Inclusion and Equity (DIE), officially introduced to counteract discrimination, have increasingly led to quite the opposite result: the exclusion of individuals who do not share a radical 'woke' ideology on identity politics (feminism, other gender activisms, critical race theory, etc.), and to the suppression of the academic freedom to discuss such dogmas. (...) This subversion of academia — disguised Trojan-horse style as universal human rights advocacy — is unacceptable because academia must be politically neutral and protect freedom of speech, a cornerstone of professional scholarly activity without which universities as we know them will slowly but surely suffocate. Our purpose here is to put together some particularly illustrative cases of such repression in a single book, testifying to a ubiquitous trend within western culture, irreducible to a few isolated complaints. The essays contained here illustrate the abuse of power, censorship and witch-hunts at many universities and research centres in the name of DIE.

In this manuscript, we extend ecological approaches and suggest ideas for enhancing athlete development by utilizing the Skilled Intentionality Framework. A broad aim is to illustrate the extent to which social, cultural and historical aspects of life are embodied in the way football is played and the skills young footballers develop during learning. Here, we contend that certain aspects of the world are “weighted” with social and cultural significance, “standing out” to be more readily perceived and simultaneously acted upon when (...) playing football. To comprehend how patterns of team coordination and athletic skill embody aspects of culture and context we outline the value-directedness of player-environment intentionality. We demonstrate that the values an individual can express are constrained by the character of the social institutions and the social order in which people live. In particular, we illuminate the extent to which value-directedness can act as a constraint on the skill development of football players “for good or ill.” We achieve this goal by outlining key ecological and relational concepts that help illustrate the extent to which affordances are value-realizing and intentionality is value-directed. To enhance coaching practice, we offer: insights into markers of skilled intentionality, and, the language of skilled intentions, as well as highlighting, an additional principle of Non-linear Pedagogy: Shaping skilled intentions, or more precisely shaping the value-directedness of player-environment intentionality. We contend that, if sport practitioners do not skilfully attend to sociocultural constraints and shape the intentions of players within training environments and games, the social, cultural, and historic constraints of their environment will do so: constantly soliciting some affordances over others and directing skill development.

Emotion can be communicated through multiple distinct modalities. However, an often-ignored channel of communication is posture. Recent research indicates that bodily posture plays an important role in the perception of emotion. However, research examining postural communication of emotion is limited by the variety of validated emotion poses and unknown cohesion of categorical and dimensional ratings. The present study addressed these limitations. Specifically, we examined individuals’ (1) categorization of emotion postures depicting 5 discrete emotions (joy, sadness, fear, anger, and disgust), (2) (...) categorization of different poses depicting the same discrete emotion, and (3) ratings of valence and arousal for each emotion pose. Findings revealed that participants successfully categorized each posture as the target emotion, including disgust. Moreover, participants accurately identified multiple distinct poses within each emotion category. In addition to the categorical responses, dimensional ratings of valence and arousal revealed interesting overlap and distinctions between and within emotion categories. These findings provide the first evidence of an identifiable posture for disgust and instantiate the principle of equifinality of emotional communication through the inclusion of distinct poses within emotion categories. Additionally, the dimensional ratings corroborated the categorical data and provide further granularity for future researchers to consider in examining how distinct emotion poses are perceived.

Este trabajo tiene un doble objetivo. En primer lugar, presentar dos paradigmas elaborados por Roberto Esposito y por Eligio Resta para pensar (con) otra racionalidad jurídica: derecho impersonal y derecho viviente. En segundo lugar, situar la genealogía de ambos paradigmas en las reflexiones suscitadas en el primer cuarto del siglo XX con Simone Weil y el debate Hans Kelsen-Eugen Ehrlich. La idea principal es plantear una singularidad jurídica en el interior de la Italian Theory.
