Cardiovascular modelling has been a major research subject for the last decade. Different cardiac models have been developed at a cellular level as well as at the whole organ level. Most of these models are defined by a comprehensive cellular modelling using continuous formalisms or by a tissue-level modelling often based on discrete formalisms. Nevertheless, both views still suffer from difficulties that reduce their clinical applications: the first approach requires heavy computational resources while the second one is not able to (...) reproduce certain pathologies.This paper presents an original methodology trying to gather advantages from both approaches, by means of a hybrid model mixing discrete and continuous formalisms. This method has been applied to define a hybrid model of cardiac action potential propagation on a 2D grid of endocardial cells, combining cellular automata and a set of cells defined by the Beeler-Reuter model. For simulations under physiological and ischemic conditions, results show that the action potential propagation as well as electrogram reconstructions are consistent with clinical diagnosis. Finally, the advantage of the proposed approach is discussed within the frame of cardiac modelling and simulation. (shrink)

Dung’s argumentation frameworks are formalisms widely used to model interaction among arguments. Although their study has been profusely developed in the field of Artificial Intelligence, it is not common to see its treatment among those less connected to computer science within the logical-philosophical community. In this paper we propose to bring to that audience a proof-theory for argument justification based on tableaux, very similar to those the Logic students are familiar with. The tableaux enable to calculate whether an argument or (...) subset of arguments are accepted or rejected in accordance to Dung’s preferred and grounded extension-based semantics. Soundness and completeness results regarding those semantics are provided. (shrink)

On July 18, 1988, workers at the Metropolitan YWCA Women's Services, a Chicago-area center designed to assist women and children who are survivors of violence and sexual assault, agreed to record in a journal their thoughts at a chosen hour during that day. Each section was written by a different worker. The purpose was to bring together separate voices, all connected through their common work with survivors to begin to understand the impact of this work on their own lives.

This paper deals with an (otherwise classical) two-(non-interacting) particle system immersed in a common stochastic zero-point radiation field. The treatment is an extension of the one-particle case for which it has been shown that the quantum properties of the particle emerge from its interaction with the background field under stationary and ergodic conditions. In the present case we show that non-classical correlations—describable only in terms of entanglement—arise between the (nearby) particles whenever both of them resonate to a common frequency of (...) the field. For identical particles the entanglement becomes maximum and must be described by totally (anti)symmetric states. (shrink)

The study of the autonomic nervous system (ANS) function has shown to provide useful indicators for risk stratification and early detection on a variety of cardiovascular pathologies. However, data gathered during different tests of the ANS are difficult to analyse, mainly due to the complex mechanisms involved in the autonomic regulation of the cardiovascular system (CVS). Although model-based analysis of ANS data has been already proposed as a way to cope with this complexity, only a few models coupling the main (...) elements involved have been presented in the literature. In this paper, a new model of the CVS, representing the ventricles, the circulatory system and the regulation of the CVS activity by the ANS, is presented. The models of the vascular system and the ventricular activity have been developed using the Bond Graph formalism, as it proposes a unified representation for all energetic domains, facilitating the integration of mechanic and hydraulic phenomena. In order to take into account the electro-mechanical behaviour of both ventricles, an electrophysiologic model of the cardiac action potential, represented by a set of ordinary differential equations, has been integrated. The short-term ANS regulation of heart rate, cardiac contractility and peripheral vasoconstriction is represented by means of continuous transfer functions. These models, represented in different continuous formalisms, are coupled by using a multi-formalism simulation library. Results are presented for two different autonomic tests, namely the Tilt Test and the Valsalva Manoeuvre, by comparing real and simulated signals. (shrink)

A paradigm shift in public health and medicine has broadened the field from a singular focus on the ill effects of negative states and psychopathology to an expanded view that examines protective psychological assets that may promote improved physical health and longevity. We summarize recent evidence of the link between psychological well-being and physical health, with particular attention to outcomes of mortality and chronic disease incidence and progression. Within this evolving discipline there remain controversies and lessons to be learned. We (...) discuss measurement-related challenges, concerns about the quality of the evidence, and other shortcomings in the field, along with a brief discussion of hypothesized biobehavioral mechanisms involved. Finally, we suggest next steps to move the field forward. (shrink)

Interest in the intersection between bilingualism and cognitive control and accessibility to neuroimaging methods have resulted in numerous studies with a variety of interpretations of the bilingual cognitive advantage. Neurocomputational Emergentism (or Neuroemergentism for short) is a new framework for understanding this relationship between bilingualism and cognitive control. This framework considers Emergence, in which two small elements are recombined in an interactive manner, yielding a non-linear effect. Added to this is the notion that Emergence can be captured in neural systems (...) using computationally inspired models. This review poses that bilingualism and cognitive control, as examined through the Neuroemergentist framework, are interwoven through development and involve the non-linear growth of cognitive processing encompassing brain areas that combine and recombine, in symbiotic and parasitic ways, in order to handle more complex types of processing. The models that have sought to explain the neural substrates of bilingual cognitive differences will be discussed with a reinterpretation of the entire bilingual cognitive advantage within a Neuroemergentist framework incorporating its neural bases. It will conclude by discussing how this new Neuroemergentist approach alters our view of the effects of language experience on cognitive control. Avenues to move beyond the simple notion of a bilingual advantage or lack thereof will be proposed. (shrink)

Relationships of physical resemblance to personality similarity and social affiliation have generated considerable discussion among behavioral science researchers. A “twin-like” experimental design explores associations among resemblance in appearance, the Big Five personality traits, self-esteem, and social attraction within an evolutionary framework. The Personality for Professionals Inventory, NEO/NEO-FFI-3, Rosenberg Self-Esteem Scale, and a Social Relationship Survey were variously completed by 45 U-LA pairs, identified from the “I’m Not a Look-Alike” project, Mentorn Media, and personal referrals. The mean U-LA intraclass correlations were (...) negligible for all Big Five personality traits on the PfPI and NEO/NEO-FFI-3. In contrast, mean ri values of.53 and.15 for monozygotic and dizygotic reared-apart twins, respectively, have been reported for these personality measures. The U-LA self-esteem correlation was also below the correlations reported for MZ and DZ reared-together twins. Finally, far fewer U-LAs expressed close social relationships than MZA and DZA twins. The present study extends earlier findings indicating that appearance is not meaningfully related to personality similarity and social relatedness. The criticism that MZ twins are alike in personality because their matched looks invite similar treatment by others is refuted. A more judicious interpretation is reactive genotype-environment correlation, namely that MZ twins’ similar personalities evoke similar reactions from others. MZ twins’ close social relations most likely derive from their perceptions of genetically based within-pair similarities that are lacking in U-LAs. (shrink)

This reply addresses observations of Drs. Larsen, Kruse, and Sweeny, and Scherer in their reviews of our published work on the link between positive psychological assets and outcomes of physical health. Inspired by Obama’s Precision Medicine Initiative we argue that the interplay between the emotion spectrum and health is likely a complex and heterogeneous amalgam of known and yet unidentified elements melding at the individual level. When exploring the emotion–health link, researchers are challenged to grapple with complex system models by (...) considering multiple hierarchies of information that span individual-level factors, genetic blueprints, and cultural and environmental context. Research is needed to more fully elucidate the mechanism through which emotion influences health, with careful consideration of differences across race/ethnicity, culture, and context. (shrink)

Different approaches have been proposed in order to achieve knowledge integration for coronary care monitoring applications, usually in the form of expert systems. The clinical impact of these expert systems, which are based only on "shallow" knowledge, has not been remarkable due to the difficulties associated with the construction and maintenance of a complete knowledge base. Model-based systems represent an alternative to these problems because they allow efficient integration of the "deep" knowledge on the underlying physiological phenomena being monitored. In (...) this work, a brief review of existing model-based systems for cardiac rhythm interpretation is presented, followed by the description of a new system forCardiac Arrhythmia Recognition by Model-Based ECG Matching (CARMEM). Fundamental characteristics of CARMEM are presented; in particular, its ability to provide on-line parameter adaptation to simulate complex rhythms and to match observed ECG signals. The proposed model can be useful for the explanation of the origin of cardiac arrhythmias and contribute towards their robust characterization in the context of coronary care units. (shrink)

Background: The Directive 2001/20/EC was an important first step towards consistency in the requirements and processes for clinical trials across Europe. However, by applying the same rules to all types of drug trials and transposing the Directive’s principles into pre-existing national legislations, the Directive somewhat failed to meet its facilitation and harmonisation targets. In the field of ethics, the Directive 2001/20/EC conditioned the way of understanding and transposing the “single opinion” process in each country. This led to a situation in (...) which two models of research ethics committees organisation systems exist, being the model in which the “single opinion” is considered to be the decision made by a single ethics committee more effective and simpler in terms of administrative and logistic workload. Method: A survey was conducted in 10 European countries. Members of the European Clinical Research Infrastructures Network working party number 1, with expertise in the field of ethics, responded. Results: There is a major heterogeneity in the composition of ethics committees among the surveyed countries based on the number of members, proportion of experts versus lay members and expertise of the scientific members. A harmonised education of the ethics committees’ membership based in common curricula is recommended by the majority of countries. Conclusions: Despite the efforts for harmonisation of the European Clinical Trial Directive, from an ethical point of view, there remains a plurality of ethics committees' systems in Europe. It is important to comprehend the individual national systems to understand the problems they are facing. (shrink)

Based on the concern of Adela Cortina and Federico Nietzsche about the difficulty, opportunity, convenience, incapacity and even the danger of acting according to rational parameters and universal principles, the document analyzes the possibilities of autonomous decision of individuals, taking into account the institutional or organizational context and the regulations that capitalism imposes on a global level. From this reflection, the relative character of the value systems and the local human relations close to each individual are recognized. They validate or (...) invalidate one or another type of behavior beyond the individual and the universal. The incursion and permanence of universal principles proper to neoliberal rationality and classical ethics are also explored. Therefore, in practice, human beings are obliged to compete with others, without breaking legal rules and universal values, to access social and economic capital that allows them to enter a particular lifestyle, an identity, constituted and represented with products and services that the market offers. A partir de la preocupación de Adela Cortina y Federico Nietzsche por la dificultad, oportunidad, conveniencia, incapacidad e incluso el peligro de actuar conforme a parámetros racionales y principios universales, se analizan las posibilidades de decisión autónoma de los individuos, teniendo en cuenta el contexto institucional u organizacional y las regulaciones que el capitalismo impone a nivel global. A partir de esta reflexión se reconoce el carácter por completo relativo de los sistemas de valores y de las relaciones humanas locales y próximas a cada individuo, que validan o invalidan uno u otro tipo de comportamiento más allá de lo individual y lo universal. También se explora la incursión y arraigamiento de principios universales propios de la racionalidad neoliberal y de la ética clásica. Se tiene, por ende, que en la práctica los seres humanos están obligados a competir unos con otros, sin quebrantar reglas legales y valores universales, para acceder al capital social y económico que les permita ingresa a un estilo de vida particular, una identidad, constituida y representada con productos y servicios que el mercado ofrece.

How can educators create space for students to practice making the worlds we are trying to collectively build? Inspired by genealogies that are grounded in and emerge from social movements, this paper uplifts the possibilities, tensions, and new questions that emerge when we take seriously the role of our classroom pedagogies. The authors offer a reflexive, methodological approach that pushes against the theory/practice divide and that stays with the importance of inhabiting theory through practice. They reflect on the role their (...) classroom pedagogies in enacting their commitments to justice, organizing their offerings around the following themes: (1) Enter, or how their learnings from previous teaching experiences shape praxis through the pauses, recalibrations, and persistent questions they provoke; (2) how they Open and create space in their classrooms through rituals and routines, and toward what ends; and finally, (3) how they aim to Build with their students within and beyond the bounds of the classroom. The authors share the guiding questions that prompted these reflections, as well as the echoes across their offerings, inviting readers to reflect on their own teaching practice in community.

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

The distinctive security features of the Spanish electronic national identity card, known as Documento Nacional de Identidad electrónico, allow us to propose the usage of this cryptographic smart card in an authentication framework that can be used during the registration and login phases of internet services where the validation of the user’s age and real identity are key elements, as it is the case for example of the so-called social networks. Using this mechanism with NFC-capable devices, the identity and age (...) of the potential user can be determined, allowing or denying the access to the service based on that information. (shrink)

In this paper I provide a preliminary account of weakness of political will (political akrasia). My aim is to use theories from the weakness of will literature as a guide to develop a model of the same phenomenon as it occurs in collective agents. Though the account will parallel the traditional view of weakness of will in individuals, weakness of political will is a distinctly political concept that will apply to group agents such as governments, institutional actors, and other political (...) collectives. I further argue that blaming inaction by collective political agents on a “lack of political will” should be understood as blaming a kind of akratic break within the deliberative process, leading to an inability of the collective agent to capitalize on existing group attitudes in order to translate them into policy or legislation. My primary example throughout will be U.S. political inaction with respect to the climate crisis. (shrink)

The judicial system in a liberal democracy is deemed to be an independent branch of government with judges free from political agendas or societal pressures. In reality, judges are often influenced by their economic and social backgrounds, gender, race, religion, and sexuality. This volume explores the representation of different identities in the judiciary in the United States. The contributors investigate the pipeline, ambition, institutional inclusion, retention, and representation of groups previously excluded from federal, state, and local judiciaries. This study demonstrates (...) how diversity on the bench improves the quality of justice, bolsters confidence in the legitimacy of the courts, and provides a vital voice in decision-making power for formerly disenfranchised populations.

An Asian Indian Hindu family chose no intervention and hospice care for their newborn with hypoplastic right heart syndrome as an ethical option, and the newborn expired after five days. Professional nursing integrates values-based practice and evidence-based care with cultural humility when providing culturally responsive family-centered culture care. Each person’s worldview is unique as influenced by culture, language, and religion, among other factors. The Nursing Team sought to understand this family’s collective Indian Hindu worldview and end-of-life beliefs, values, and practices, (...) in view of the unique aspects of the situation while the team integrated evidence-based strategies to provide family-centered culture care. Parental care choices conflicted with those of the Nursing Team, and some nurses experienced moral distress and cultural dissonance when negotiating their deeply held cultural and religious views to advocate for the family. The inability to reconcile and integrate a stressful or traumatic experience impacts nurses’ well-being and contributes to compassion fatigue. Nurses need to be intentional in accessing interventions that promote coping and healing and moral resilience. Reflection and cultural humility, assessment, and knowledge in context, increase evidence-based culture care and positive outcomes. U.S. society’s views on ethical behavior continue to evolve, and some may argue that the law should place more limits on parents’ right to choose or to refuse treatment for their infants and children. Moral distress can lead to moral resilience and satisfaction of compassion when nurses provide family-centered culture care with cultural responsiveness and integrate values-based practice with evidence-based care, and aim to first do no harm.
