Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and (...) its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes. (shrink)

El Amor y la Nada son dos huellas medievales por las que han transitado los espíritus inquietos del siglo XX y del siglo XXI en busca de señales para fundar “nuevos comienzos” de raíces antiguas. En sus últimos escritos Simone Weil dejó constancia de su admiración por el camino del anonadamiento y del amor puro que había encontrado en un “anónimo” de la mística francesa del siglo XIV, El espejo de las almas simples , cuya autoría, se comprobaría tiempo después, (...) pertenecía a Margarita Porete, condenada a la hoguera en 1310. A partir de este puente trazado por dos francesas heridas por la belleza y el dolor, nuestro propósito es realizar una lectura estético teológica, a fin de mostrar que, a través de la vía negativa del desasimiento, el “Amor nuevo”, que libremente se manifiesta en la figura del “espejo”, es quien pone en marcha cada nuevo comienzo en la historia. .

In this article, I argue that gender is a primary cultural frame for coordinating behavior and organizing social relations. I describe the implications for understanding how gender shapes social behavior and organizational structures. By my analysis, gender typically acts as a background identity that biases, in gendered directions, the performance of behaviors undertaken in the name of organizational roles and identities. I develop an account of how the background effects of the gender frame on behavior vary by the context that (...) different organizational and institutional structures set but can also infuse gendered meanings into organizational practices. Next, I apply this account to two empirical illustrations to demonstrate that we cannot understand the shape that the structure of gender inequality and gender difference takes in particular institutional or societal contexts without taking into account the background effects of the gender frame on behavior in these contexts.

Background The ambulance service provides emergency care to meet the patient’s medical and nursing needs. Based on professional nursing values, this should be done within a caring relationship with a holistic approach as the opposite would risk suffering related to disengagement from the patient’s emotional and existential needs. However, knowledge is sparse on how ambulance personnel can meet caring needs and avoid suffering, particularly in conjunction with urgent and emergency situations. Aim The aim of the study was to explore ambulance (...) nurses’ experiences of relationships with patients in urgent and emergency situations. Methods Data collection was performed using individual open-ended interviews with six ambulance nurses. The data were analyzed using a thematic analysis. Results Relationships with patients during urgent and emergency assignments emerged as three themes: “ Ambiguous silence,” “ Professional competence” and “ Challenging inadequacy” comprising eight sub-themes in total. The result shows that the ambulance nurses found it difficult to prioritize between medical care and establishing a caring relationship with the patient. However, sometimes a wordless relationship was perceived sufficient and considered a first step towards a verbal relationship. Conclusions Ambulance nurses experience that a caring relationship cannot and does not need to be prioritized in the acute stage. This uncovers a dichotomy approach to medical care versus caring relationships that exclude a holistic approach. Thus, patients’ emotional, existential and physical needs are not considered as equally important. Clinical relevance: It is important to stimulate reflection on core ethical nursing values, in training and simulation exercises among clinically active ambulance nurses. (shrink)

Intersubjectivity impairment has been considered the main pathogenic nucleus of schizophrenia. Enriching this concept with references to Scheler’s phenomenology, our hypothesis is that schizophrenic subjects are affected by a deeper impairment: the inability to resonate with unipathic affectivity. Fragmentation of the Leibschema, valueception impairment, and the lack of vital impulse are, in our hypothesis, the original alterations of the schizophrenic bodily experience from which all relational impairments originate. Our proposal is, therefore, to enhance a psychotherapy that does not only focus (...) on the verbal level, but endeavors to touch the patient’s Leib, focusing on emotional sharing and on the development of a sense of cohesion of one’s body as the starting point for accessing intersubjectivity.

Synthetic biology is a cutting-edge area of research that holds the promise of unprecedented health benefits. However, in tandem with these large prospective benefits, synthetic biology projects entail a risk of catastrophic consequences whose severity may exceed that of most ordinary human undertakings. This is due to the peculiar nature of synthetic biology as a ‘threshold technology’ which opens doors to opportunities and applications that are essentially unpredictable. Fears about these potentially unstoppable consequences have led to declarations from civil society (...) groups calling for the use of a precautionary principle to regulate the field. Moreover, the principle is prevalent in law and international agreements. Despite widespread political recognition of a need for caution, the precautionary principle has been extensively criticized as a guide for regulatory policy. We examine a central objection to the principle: that its application entails crippling inaction and incoherence, since whatever action one takes there is always a chance that some highly improbable cataclysm will occur. In response to this difficulty, which we call the ‘precautionary paradox,’ we outline a deliberative means for arriving at threshold of probability below which potential dangers can be disregarded. In addition, we describe a Bayesian mechanism with which to assign probabilities to harmful outcomes. We argue that these steps resolve the paradox. The rehabilitated PP can thus provide a viable policy option to confront the uncharted waters of synthetic biology research. (shrink)

Cognitive gadgets are distinctively human cognitive mechanisms – such as imitation, mind reading, and language – that have been shaped by cultural rather than genetic evolution. New gadgets emerge, not by genetic mutation, but by innovations in cognitive development; they are specialised cognitive mechanisms built by general cognitive mechanisms using information from the sociocultural environment. Innovations are passed on to subsequent generations, not by DNA replication, but through social learning: People with new cognitive mechanisms pass them on to others through (...) social interaction. Some of the new mechanisms, like literacy, have spread through human populations, while others have died out, because the holders had more students, not just more babies. The cognitive gadgets hypothesis is developed through four case studies, drawing on evidence from comparative and developmental psychology, experimental psychology, and cognitive neuroscience. The framework employed – cultural evolutionary psychology, a descendant of evolutionary psychology and cultural evolutionary theory – addresses parallel issues across the cognitive and behavioural sciences. In common with evolutionary developmental biology and the extended evolutionary synthesis, cultural evolutionary psychology underlines the importance of developmental processes and environmental factors in the emergence of human cognition. In common with computational approaches, it emphasises the power of general-purpose mechanisms of learning. Cultural evolutionary psychology, however, also challenges use of the behavioural gambit in economics and behavioural ecology, and rejects the view that human minds are composed of “innate modules” or “cognitive instincts.”.

This book investigates Hegel’s interpretation of the mystical philosophy of Jakob Böhme, considered in the context of the reception of Böhme in the 18th and 19th centuries, and of Hegel’s own understanding of mysticism as a philosophical approach. The three sections of this book present: the historical background of Hegel’s encounter with Böhme’s writings; the development of two different conceptions of mysticism in Hegel’s work; and finally Hegel’s approach to Böhme’s philosophy, discussing in detail the references to Böhme both in (...) published writings and manuscripts. According to Hegel, Böhme is “the first German philosopher”. The reason for placing Böhme at the very beginning of German philosophy is that Hegel considers him to be a profound thinker, despite his rudimentary education. Hegel’s fascination with Böhme mainly concerns the mystic’s understanding of the symbiotic relation between God and his opposite, the Devil: he considers this to be the true speculative core of Böhme’s thought. By interpreting Böhme, Hegel intends to free the speculative content of his thought from the limitations of the inadequate, barbarous form in which the mystic expressed it, and also to liberate Böhme from the prejudices surrounding his writings, placing him firmly in the territory of philosophy and detaching him from the obscurity of esotericism. Combining historical reconstructions and philosophical argumentation, this book guides the reader through an important phase in German philosophy, and ultimately into an inquiry about the relationship between mysticism and philosophy itself.

The procedures for structuring clinical ethics case reflections in a childhood cancer care setting are presented, including an eight-step model. Four notable characteristics of the procedures are: members of the inter-professional health care team, not external experts, taking a leading role in the reflections; patients or relatives not being directly involved; the model explicitly addressing values and moral principles instead of focussing exclusively on the interests of involved parties; using a case-based rather than principle-based method. By discusing the advantages and (...) disadvantages of the proposed procedures, our paper aims to contribute to the literature on models and procedures for ethical analysis that can be used in clinical settings. It is suggested that our proposed procedures have some advantageous features when it comes to promoting health care staff’s learning to structure their thinking about ethical issues. (shrink)

Si bien la cirugía es parte fundamental de la medicina y de gran relevancia en la sociedad actual, no ha sido tomada en cuenta por la filosofía de la medicina. Debido a la naturaleza eminentemente práctica de la cirugía, una indagación sistemática nos permitirá, entre otros aspectos, dilucidar rasgos generales de las prácticas científicas en las que el conocimiento tácito es esencial. Por lo que, con la finalidad de integrar a la cirugía dentro del marco general de la filosofía de (...) la medicina, se propone un primer corpus tentativo de problemas en los que puede centrarse la filosofía de la cirugía, que incluyen: cuestiones epistémicas acerca del aprendizaje de las habilidades quirúrgicas y su transformación; la evidencia utilizada en cirugía, así como la forma en la que los cirujanos validan sus intervenciones frente a otras especialidades médicas y si está justificada epistémicamente la falta de ensayos clínicos aleatorizados; finalmente se examina la forma de aprobación de los dispositivos médicos que son ampliamente utilizados en cirugía. Esto, mostrará que la filosofía de la cirugía tiene el potencial para establecerse como un área autónoma dentro de la filosofía de la medicina. (shrink)

This article describes Cosa Nostra bosses’ psychological characteristics starting from research data collected over almost twenty years. Through the use of fragments of interviews to justice collaborators and their wives, children, and sisters-in-law, we analyze the boss’ role and relational context. This article also reports the results of a recent research on the relationship between boss and white-collar workers, carried out through the analysis of environmental tapping recorded at a famous Sicilian Mafia boss’ house: Giuseppe Guttadauro. This research highlights the (...) psychological diversity the relationship between boss and white-collar worker is based on. The analysis of environmental tapping transcriptions has also allowed discovery of the main relational modalities used by the boss and white-collar worker in their conversations. (shrink)

Dennett, a philosopher, and Griffin, an ethologist, have recently presented influential arguments promoting the extended use of intentional language by students of animal behavior. This essay seeks to elucidate and to contrast the claims made by each of these authors, and to evaluate their proposals primarily from the perspective of a practicing comparative psychologist or ethologist. While Griffin regards intentional terms as explanatory, Dennett assigns them a descriptive function; the issue of animal consciousness is central to Griffin's program and only (...) tangentially related to Dennett's. The philosopher's arguments are founded upon a more coherent metaphysics, but Dennett neglects to substantiate his claim that animal competences can be most readily modelled by artificial intelligence specialists when they are described in intentional terms. Both authors assume that some examples of animal behavior should not be given an intentional characterization, but neither provides adequate guidelines for the identification of cases belonging to this negative set.

The Protein Ontology provides terms for and supports annotation of species-specific protein complexes in an ontology framework that relates them both to their components and to species-independent families of complexes. Comprehensive curation of experimentally known forms and annotations thereof is expected to expose discrepancies, differences, and gaps in our knowledge. We have annotated the early events of innate immune signaling mediated by Toll-Like Receptor 3 and 4 complexes in human, mouse, and chicken. The resulting ontology and annotation data set has (...) allowed us to identify species-specific gaps in experimental data and possible functional differences between species, and to employ inferred structural and functional relationships to suggest plausible resolutions of these discrepancies and gaps.

What is the relationship between imitation and culture? This article charts how definitions of imitation have changed in the last century, distinguishes three senses of “culture” used by contemporary evolutionists (Culture1–Culture3), and summarises current disagreement about the relationship between imitation and culture. The disagreement arises from ambiguities in the distinction between imitation and emulation, and confusion between two explanatory projects—the anthropocentric project and the cultural selection project. I argue that imitation gives cultural evolution an inheritance mechanism for communicative and gestural (...) skills (but not technological skills), and cultural selection yields the cognitive mechanisms that make imitation possible.

Wolfgang Pauli referred to him as 'my discovery,' Robert Oppenheimer described him as 'one of the most gifted theorists' and Niels Bohr found him enormously stimulating. Who was the man in question, Gunnar Källén (1926-1968)? His appearance in the physics sky was like a shooting star. His contributions to the scientific debate caused excitement among young and old. Similar to his friend and mentor, Wolfgang Pauli, he demanded honesty and rigor in physics - a distinct dividing line between fact and (...) speculation. In his obituary, Arthur S. Wightman would write: 'Gunnar Källén was a proud continuer of the tradition in quantum field theory established by Wolfgang Pauli. His papers on quantum electrodynamics in the period 1950-1954 carried the non-perturbative approach to quantum electrodynamics forward to a point beyond which very little essential progress has been made up to the present day. At the time I was trying to puzzle out the grammar of the language of quantum field theory, and here was Källén already writing poetry in the language!'. In addition to being a remarkable scientist, Källén had a very interesting personality, well worth exploring. In her book, physicist Cecilia Jarlskog traces both the personal and scientific trajectory of this unsung hero of the early days of high-energy physics and quantum field theory. A number of invited contributions by members of the Källén family and distinguished researchers from the field, all of them personally acquainted with Källén, combine to form an authentic portrait of the researcher and the man. Last but not least, the reader will become acquainted with some aspects of the history of particle physics in those days, as related by Källén and those who corresponded with him. A commented selection of his most important and not easily accessible papers is included as an added bonus for specialists. (shrink)

Previous studies on parenting adult children with ASD were scarce, and their intervention protocols mainly were derived from established work with children. Development of an applicable adult-oriented protocol and demonstration of its effectiveness is warranted. The present study outlined the development and evaluation of Core Autism Parenting Skills, which targets to enhance parenting self-efficacy intervention for adult children with ASD by addressing two intervention goals in parallel: acquisition of parenting skills and cultivating positive attributes. In CAPS, PSE is operationalised into (...) four parent roles: to observe, reinforce, empathise, and accompany, each with requisite attributes, skills, and prescribed training. Twenty-seven parents with adult children with ASD were recruited. They completed measures assessing their PSE, competence in the four parent roles, and emotional well-being at pre-training, post-training and 2-month follow-up. The intervention was well-received by the participants and reported significant improvements in PSE, parent role competence at post-training and 2-month follow-up. The applicability of PSE and parent role competence in constructing effective parenting intervention for adult children with ASD was supported. (shrink)

RESUMO Neste artigo, analiso um conjunto de seis cartões comerciais pertencentes a uma duradoura campanha de marketing da Liebig Extract of Meat Co. A análise crítica dos textos promocionais produzidos na virada do século XX oferece insights significativos sobre os mecanismos discursivos que contribuíram para a hegemonização do capitalismo burguês. Diferentemente de outras formas de publicidade, os cartões comerciais não são rapidamente descartados e esquecidos; pelo contrário, eles podem se distanciar dos produtos anunciados para se tornar parte dos discursos populares (...) de instrução em massa. Como produtos e produtores de ideologias capitalistas, os anúncios são um local privilegiado de inscrição do capitalismo e, portanto, se prestam a uma análise crítica. Minha análise mostra como os textos selecionados se baseiam e texturizam os discursos do progresso, impregnados como crenças colonialistas e desencadeando uma cadeia de ações pela qual, mesmo antes de realmente obterem os cartões, são promulgadas ações e crenças capitalistas. ABSTRACT In this paper, I analyze a set of six trading cards belonging to Liebig’s Extract of Meat Co. long-standing marketing campaign. The critical analysis of promotional texts produced at the turn of the 20th century offer meaningful insights on the discursive mechanisms that contributed to the hegemonization of bourgeois capitalism. Unlike other forms of advertising, trading cards are not rapidly discarded and forgotten; on the contrary, they can detach themselves from the advertised products to become part of popular discourses of mass instruction. As both products and producers of capitalist ideologies, ads are a privileged site of inscription of capitalism, and thus lend themselves to a critical analysis. My analysis shows how the selected texts draws on and textures the discourses of progress, inculcated as colonialist beliefs and triggering an actional chain whereby, even before they actually obtained the cards, capitalist actions and beliefs are enacted.

En el presente artículo se pone de relieve el impacto que tienen las reglas estéticas de una cultura sobre la configuración de las sociopolíticamente denominadas ‘identidades de género’ de los sujetos. Se trabaja con la agencialidad de la imagen fotográfica, a partir del cual se describe el carácter performativo de la fotografía, que opera tanto en un sentido normativo como en uno subversivo. El objetivo general de este artículo es situar a la parodia estética como una herramienta política potencialmente capaz (...) de sublevarse contra los valores éticos y estéticos de los géneros sexuales dominantes en la cultura occidental contemporánea. Para ello se recurre al análisis de fotografías consideradas como dispositivos de construcción de subjetividad. Se describen distintas estéticas de género constitutivas del imaginario social de esta cultura, la normativa, la abyecta y la paródica. A la parodia estética se le atribuyen tres características que resultan fundamentales para llevar a cabo la tarea de desestabilizar las normas estéticas hegemónicas de las identidades de género, a saber, la intransitividad, concepto tomado de la teoría de Wittgenstein, la repetición, noción que situamos en la obra de Butler, y el movimiento, principio derivado de nuestro análisis.

Background: Previous studies have investigated the effects of dance interventions on Parkinson’s motor and non-motor symptoms in an effort to develop an integrated view of dance as a therapeutic intervention. This within-subject study questions whether dance can be simply considered a form of exercise by comparing a Dance for Parkinson’s class with a matched-intensity exercise session lacking dance elements like music, metaphorical language, and social reality of art-partaking.Methods: In this repeated-measure design, 7 adults with Parkinson’s were tested four times; before (...) and after a Dance for Parkinson’s class, as well as before and after a matched-intensity exercise session. Physiological measures included heart rate and electrodermal activity. Self-reported affect and body self-efficacy were collected. Gait symmetry and dual task cost were analyzed using the 6 min walking test and Timed-Up-and-Go test, respectively.Results: Average heart rate was the same for both conditions, while electrodermal activity was higher during Dance for Parkinson’s. Significant differences were found in body self-efficacy, beauty subscale, symmetry of gait, and dual task performance.Conclusion: Dance, compared to an exercise intervention of matched intensity, yields different outcomes through the means of intrinsic artistic elements, which may influence affective responses, the experience of beauty, self-efficacy, and gait performance.

It seems trivial to identify sound sequences as music or speech, particularly when the sequences come from different sound sources, such as an orchestra and a human voice. Can we also easily distinguish these categories when the sequence comes from the same sound source? On the basis of which acoustic features? We investigated these questions by examining listeners’ classification of sound sequences performed by an instrument intertwining both speech and music: the dùndún talking drum. The dùndún is commonly used in (...) south-west Nigeria as a musical instrument but is also perfectly fit for linguistic usage in what has been described as speech surrogates in Africa. One hundred seven participants from diverse geographical locations (15 different mother tongues represented) took part in an online experiment. Fifty-one participants reported being familiar with the dùndún talking drum, 55% of those being speakers of Yorùbá. During the experiment, participants listened to 30 dùndún samples of about 7s long, performed either as music or Yorùbá speech surrogate (n= 15 each) by a professional musician, and were asked to classify each sample as music or speech-like. The classification task revealed the ability of the listeners to identify the samples as intended by the performer, particularly when they were familiar with the dùndún, though even unfamiliar participants performed above chance. A logistic regression predicting participants’ classification of the samples from several acoustic features confirmed the perceptual relevance of intensity, pitch, timbre, and timing measures and their interaction with listener familiarity. In all, this study provides empirical evidence supporting the discriminating role of acoustic features and the modulatory role of familiarity in teasing apart speech and music. (shrink)
