The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary (...) characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

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 focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (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)

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)

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)

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)

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)

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)

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.

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.

Resumen Vivimos en un mundo cada vez más polarizado entre ricos y pobres. Entre un pequeño grupo de personas que concentra y controla la riqueza mundial, y la gran mayoría de la población que no cuenta con las condiciones indispensables para poder vivir. Por otra parte, la globalización económica promueve un modelo de humanidad basado en el consumismo. El ser humano ha identificado la búsqueda de la felicidad con el comprar y adquirir los nuevos modelos que la publicidad impone. Nos (...) estamos acabando al planeta -incluyendo a la humanidad- y las consecuencias son evidentes: calentamiento global, contaminación, extinción de especies, violencia, migración, etc. Por otra parte, la acumulación de recursos en manos de unos cuantos es algo que también destruye a los ricos, los deshumaniza. Consideramos por tanto que si bien la pobreza, como carencia de lo indispensable para poder vivir dignamente, es un problema que debemos solucionar; por otra parte, hay otro tipo de “pobreza” entendida como virtud, que nos ayuda a vivir más plenamente, y es aquella que nos proporciona libertad para centrarnos en lo esencial: la familia, la humanidad, el mundo y Dios. El objetivo del presente trabajo es pasar de la pobreza como problema a la pobreza como virtud.We live in a world where the gap between the rich and the poor is increasing. In a world where a small group of people concentrates and controls the wealth, and the rest of the population is lacking the indispensable conditions for living. On another hand, economic globalization promotes a model of humanity based on consumerism. Human beings have related search of happiness with acquiring commodities and models imposed by advertising. We are destroying the planet -including humanity- and the consequences are evident: global warming, pollution, endangered species, violence, migration, etc. In addition, accumulating resources is dehumanizing and destroying the wealthy societies. We consider, that poverty understood as lacking financial resources is a problem that needs a resolution; but also, poverty, understood as virtue, help us to live fully and provides freedom, so we can focus on the essentials: family, humanity, the world and God. The objective of this work is to pass from poverty as a problem, to poverty as a virtue. (shrink)

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.

The notion of conceptual space, proposed by Gärdenfors as a framework for the representation of concepts and knowledge, has been highly influential over the last decade or so. One of the main theses involved in this approach is that the conceptual regions associated with properties, concepts, verbs, etc. are convex. The aim of this paper is to show that such a constraint—that of the convexity of the geometry of conceptual regions—is problematic; both from a theoretical perspective and with regard to (...) the inner workings of the theory itself. On the one hand, all the arguments provided in favor of the convexity of conceptual regions rest on controversial assumptions. Additionally, his argument in support of a Euclidean metric, based on the integral character of conceptual dimensions, is weak, and under non-Euclidean metrics the structure of regions may be non-convex. Furthermore, even if the metric were Euclidean, the convexity constraint could be not satisfied if concepts were differentially weighted. On the other hand, Gärdenfors’ convexity constraint is brought into question by the own inner workings of conceptual spaces because: some of the allegedly convex properties of concepts are not convex; the conceptual regions resulting from the combination of convex properties can be non-convex; convex regions may co-vary in non-convex ways; and his definition of verbs is incompatible with a definition of properties in terms of convex regions. Therefore, the mandatory character of the convexity requirement for regions in a conceptual space theory should be reconsidered. (shrink)

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)

This paper defines in a formal and computational way the notion of ‘consilience’, a term introduced by Whewell in 1847 for the evaluation of scientific theories. Informally, as has been used to date, a model or theory is ‘consilient’ if it is predictive, explanatory and unifies the evide-nce. Centred in a constructive framework, where new terms can be intro-duced, we essay a formalisation of the idea of unification based on the avoidance of ‘sepa-ration’. However, it is soon manifest that this (...) classical approach is vulnerable to the introduction of fantastic concepts to unify disparate sub-theories. Our second approach is constructed by using a detailed evaluation of the relationship between the theory and the evid-ence by means of reinforcement propagation. With the use of reinfor-cement, fantastic concepts can be better detected and the role of con-silience for theory construction and revision can be specialised for dif-ferent inference mechanisms like explanatory induction, abduction, deduc-tion and analogy.

The assembly of products or components by operators in industries is a complex task with recurring problems. In these processes, operators often make errors that can lead to defective products. Therefore, they need to be inspected later to verify their correct assembly. The main problems are caused by several reasons including high employee turnover, lack of experience in manufacturing specific products or confusion in interpreting instructions to assemble similar components. In this paper, a novel structured language aimed to describe the (...) required actions to manufacture a product in industrial assembly environments is presented. The main contribution is to provide a formal language to feed automatic systems that can verify through visual control whether the actions performed by the operator are carried out following the standard described by this language. In general, the use of this formal language will allow to minimize the negative impact of errors during assembly and to reduce waste in many forms in the industry. (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 report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness. To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST). A general qualitative evaluation criteria for cognitive (...) architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems.
