In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)
Econometric reduction theory provides a comprehensive probabilistic framework for the analysis and classification of the reductions (simplifications) associated with empirical econometric models. However, the available approaches to econometric reduction theory are unable to satisfactorily accommodate a commonplace theory of social reality, namely that the course of history is indeterministic, that history does not repeat itself and that the future depends on the past. Using concepts from philosophy this paper proposes a solution to these shortcomings, which in addition permits new reductions, (...) interpretations and definitions. (shrink)
In the present contribution, the problem of establishing tuning rules to proportional retarded controller for LTI systems is addressed. Based on the D-decomposition methodology and σ-stability analysis, analytic conditions are determined on the parameters of a delayed controller that guarantee us that the system response reaches the maximal decay rate. The conditions presented in this paper are tested experimentally in tracking tasks of a flexible joint robotic arm.
The thesis of political theology holds that all justificatory theories of the state rely on metaphysical assumptions, rather than just empirical facts and accepted political conventions. For this reason, the thesis challenges liberal theories that justify the state on the basis of individual autonomy and popular will. The thesis is controversial because many theorists believe that metaphysical assumptions introduce decisionism – the view that a state depends on the unrestrained personal decision of a ruler – to the theory of the (...) state. But, does political theology entail decisionism? This article argues that decisionism does not follow necessarily from political theology because an omnipotent deciding sovereign is only one of many possible metaphysical assumptions in theology. It illustrates this claim with examples from the philosophy of Nicholas Cusanus and process philosophy. This conclusion challenges two different entrenched views: first, that the modern state is a continuation of theistic beliefs; and second, that metaphysical discussions have no place in contemporary normative political theory.

Threatened aboriginal cultures provide valuable criteria for fruitful criticism of the dominant Western cultural paradigm and perceptual model, which many take for granted as the inevitable path for humankind to follow. However, this Western model has proven itself to be imprecise and limiting. It obscures fundamental aspects of human nature, such as the mythical, religious dimension, and communication with the Cosmos. Modern technology, high-speed communication and mass media affect our ability to perceive reality and respond to it. Non-Western worldviews could (...) help us to regain meaningful communication with Nature and to learn new ways of perceiving our world. (shrink)
On Borders asks when are borders legitimate, and it offers a new theory to answer the question. The book challenges critical and normative theories that criticize or justify borders solely in terms of identity, and instead frames borders and border legitimacy from the perspective of place and presence. Instead of thinking of borders as the exclusionary limit of identity groups, the book develops a theory of territorial jurisdictions grounded on place-specific relations, giving central roles to urban settings and the environment. (...) Paulina Ochoa Espejo calls this the "watershed model" of territorial rights and borders. (shrink)
Democracy is usually conceived as based on self-rule or rule by the people, and it is this which is taken to ground the legitimacy of the democratic form of government. But who constitutes the people? Democratic political theory has a potentially fatal weakness at its core unless it can answer this question satisfactorily. In _The Time of Popular Sovereignty_, Paulina Ochoa Espejo examines the problems the concept of the people raises for liberal democratic theory, constitutional theory, and critical theory. (...) She argues that to solve these problems, the people cannot be conceived as simply a collection of individuals. Rather, the people should be seen as a series of events, an ongoing process unfolding in time. She then offers a new theory of democratic peoplehood, laying the foundations for a new theory of democratic legitimacy. (shrink)

Who is made unfree by systematic injustices, like poverty, patriarchy, or race? Many think the answer is, "The victims." Who has duties to challenge these injustices? Many say, "The privileged." To both, this book offers a different answer: "Everyone." Everyone is made unfree by such injustices: victims, bystanders, and perpetrators alike. For such injustices try to suppress everyone's resistance to their workings, and that suppression counts as arbitrary power. Moreover, everyone has a duty to themselves to be free. Examining three (...) major global injustices--gender, race, and poverty--this book thus offers a new defence of the doctrine of the global left, "No one is free while others are oppressed!".

Introducción: se presenta un ensayo cuyo objetivo es fijar posiciones frente al resumen del Informe de la Comisión sobre Determinantes Sociales de la Salud (CDSS) proponer las acciones políticas que los movimientos sociales en salud deben emprender. Análisis: las recomendaciones de la CDSS no enfocan el problema en toda su compleja naturaleza y en especial desconoce la influencia decisiva de la formación económica social sobre la situación crítica de la salud en el mundo. Acción: se propone la unidad de los (...) movimientos sociales que actúan en el campo de salud para luchar contra los efectos de las políticas económicas y sociales dominantes en el mundo: reducción del papel del estado, privatización de servicios, desregulación laboral, privatización de la seguridad social, políticas migratorias y otras. Denunciemos toda política neoliberal en relación con la salud, practiquemos la solidaridad con los que luchan contra esas políticas, derrotemos el monopolio mediático neoliberal, enfocar el problema de los DSS como asunto político social, no técnico y defendamos el papel protagónico del estado, único capaz de asegurar servicios de salud al alcance de todos. Conclusión: "Nuestro deber es luchar", como nos advirtió Fidel Castro. Introduction: An essay is presented in order to set positions against the Report´s summary of the Commission on social determinants of public health (CSDPH) that suggests the political actions to be undertaken by Health social movements. Analysis: The CSDPH recommendations do not focus the problem in all its complex nature and do not recognize the decisive influence of the social economic formation on the critical situation of Health in the world. Action: unity of social movements acting in the field of health to fight against the effects of the dominant economic and social policies of today´s world: reduction of the role of the State, privatization of services, labour deregulation, privatization of social security, migratory policies and others. We denounce any neo-liberal policy in relation to Health. Let´s support those who struggle against those policies; let´s defeat the neoliberal media monopoly, let´s focus on the problem of social determinants as a sociopolitical issue , not as a technical one; let´s defend the leading role of the State, the only one capable to ensure health services to everyone. Conclusion: As Fidel Castro expressed: "Our duty is to fight. (shrink)
The introduction of Viagra in Japan is largely associated with the construction of ‘abject masculinities’. The approval of the drug comes amidst worries about hormones polluting the environment and Japanese men's unwillingness to perform their ‘appropriate gender role’ in a country coping with problems in the economy, a growing number of unmarried people, an ageing population and declining birth rates. In this article, I analyse how impotence, gender and reproduction are entangled in the ways in which Japanese physicians report erectile (...) dysfunction and prescribe Viagra. The accounts of physicians, taken from the media and scientific reports, show that medical doctors tend to uphold ‘the Viagrization of ED’, which will lead to the Viagrization of Japan. Despite discourses on medicalized sexuality, reproductive behaviour and promotion of childbirth, the politics of Viagra largely promote male recreational sex with substantial benefits for the pharmaceutical and sex industries. Also, the politics of Viagra seem to underpin the commodification of a sexualized male body that ignores the reproductive health concerns of Japanese men. (shrink)
BackgroundThe effect of orgasm on the development and shaping of partner preferences may involve a catalysis of the neurochemical mechanisms of bonding. Therefore, understanding such process is relevant for neuroscience and psychology.MethodsA systematic review was carried out using the terms Orgasm, Sexual Reward, Partner Preference, Pair Bonding, Brain, Learning, Sex, Copulation.ResultsIn humans, concentrations of arousing neurotransmitters and potential bonding neurotransmitters increase during orgasm in the cerebrospinal fluid and the bloodstream. Similarly, studies in animals indicate that those neurotransmitters and others modulate (...) the appetitive and consummatory phases of sexual behavior and reward. This suggests a link between the experience of orgasm/sexual reward and the neurochemical mechanisms of pair bonding. Orgasm/reward functions as an unconditioned stimulus. Some areas in the nervous system function as UCS-dete... (shrink)
Partner preferences are expressed by many social species, including humans. They are commonly observed as selective contacts with an individual, more time spent together, and directed courtship behavior that leads to selective copulation. This review discusses the effect of conditioning on the development of heterosexual and homosexual partner preferences in rodents. Learned preferences may develop when a conditioned stimulus (CS) is associated in contingency with an unconditioned stimulus (UCS) that functions as a reinforcer. Consequently, an individual may display preference for (...) a partner that bears a CS. Some UCS may be more or less reinforcing, depending on when they are experienced, and may be different for males and females. For example, it could be that, only during periods of early development, that stimuli associated with nurture and juvenile play become conditioned. In adulthood, other stimuli such as sexual reward, cohabitation, mild stress, or even pharmacological manipulations may function as reinforcers to condition partner preferences. Evolutionary biologists and psychologists must take into consideration the idea that an individual’s experience with reward (i.e. sexual and pharmacological) can override presumably ‘innate’ mate choices (e.g. assortativeness and orientation) or mate strategies (e.g. monogamy or polygamy) by means of Pavlovian and operant contingencies. In fact, it is likely as innate to learn about the environment in ways that maximize reward and minimize aversive outcomes, making so-called ‘proximate’ causes (e.g. pleasure) ultimately more powerful predictors of social behavior and choice than so-called ‘ultimate’ causes (e.g. genetic or reproductive fitness).

This book explores policy innovation for same-sex couples throughout the Americas and includes same-sex marriage legislation, civil unions, and other new developments for same-sex couples throughout the Americas at both national and sub-national levels. This scholarship is innovative because though much has been written regarding developments in North America, there is very little work dealing with recent developments in the rest of the Americas.
Traditionally, in Spain bullfighting represents an ancient and well-respected tradition and a combined brand of sport, art and national identity. However, bullfighting has received considerable criticism from various segments of society, with the concomitant rise of the animal rights movement. The paper reports a survey of the Spanish citizens using a face-to-face survey during January 2016 with a total sample of 2522 citizens. The survey asked about degree of liking and approving; culture, art and national identity; socio-economic aspects; emotional perception (...) and animal welfare. The hypothesis proposed that the perception of bullfights may be affected by gender, age, occupation, origin and nationality of the persons surveyed. The hypothesis was confirmed. The majority of citizens surveyed do not like bullfights and great majorities do not attend or watch such events. Two extreme clusters were described: one representing favorable attitude towards bullfighting and other against bullfighting. The proportion of indifferent persons was important. Women and young people showed a more favorable attitude towards animal welfare issues associated with these events. Rural people were more accepting bullfights than urban people. Students were more anti-bullfight than those in other occupations. Additionally, technical economic factors made people favor more bullfights. The growth of claim against bullfights establishes an element of a far more multifaceted phenomenon that animal cruelty per se and support of a new paradigm called social change in countries as Spain.

Esta reflexión evidencia cómo desde los años sesenta Amílcar Osorio produce una práctica artística en procura de la desinstitucionalización de la literatura y del arte, al situar sus objetivos estéticos no solo en las letras como posibilidad narrativa y poética, sino en la utilización de lo visual, el espacio y la vida misma como recurso artístico. Con esto el autor consigue difuminar las fronteras entre literatura, artes visuales y de acción, y logra producir lo que se puede considerar hoy una (...) práctica intermedial, al tomar estrategias propias del arte conceptual que le permiten conectar la vida cotidiana, la literatura, las ideas como expresión artística, la imagen y la performance.

Mediante un lenguaje paradojal, la obra de Miguel de Unamuno plantea de modo recurrente la cuestión de Dios, especialmente en el libro Del sentimiento trágico de la vida. Lo plantea bajo dos perspectivas: la del Dios pensado y la del Dios sentido. En ambos casos se trata de un Dios personal cuyo encuentro tiene lugar por vía de la intuición vivencial y el recogimiento. Se reconocen allí coincidencias con San Juan de la Cruz, y en general, con la mística al (...) privilegiar el sentimiento frente al entendimiento, la vivencia frente a la racionalidad. (shrink)
En los tiempos que corren parece ser que se ha ido gestando un nuevo tipo de sociedad en la que el consumismo es el núcleo moral de la vida. Todo hoy está sometido a la lógica de un mercado que tiene como nota preponderante la seducción; de ahí que lo lúdico y lo estético pretendan operar hoy en día como ejes integradores de la cultura. Embellecerse exteriormente y divertirse han devenido deberes, tanto que la gente suele sentirse avergonzada de trabajar (...) mucho y no gozar más, de no disponer de más tiempo libre para disfrutar más, con lo cual resulta evidente que seguimos viviendo bajo el signo de la desmesura: en la Modernidad vivimos para trabajar, hoy trabajamos para consumir.

Vocación es una categoría ética, que alude a la perspectiva en que ponemos nuestra vida y a las preferencias que la van orientando en la praxis cotidiana. En sentido ético, la vocación tiene cuatro notas definitorias: Las elecciones cotidianas, la prudencia, la realización efectiva del proyecto fundamental y la entrega personal y comunitaria a un quehacer, y a éstas hay que adicionarles la vertiente religiosa o trascendente. La tarea moral, consiste en llegar a ser lo que se puede ser, con (...) lo que se es, de donde resulta que el verdadero destino es nuestro ser mismo: «Llega a ser el que eres». La vocación más que un llamado es «un êthos de fidelidad a sí mismo», un programa de vida, un afán de ser responsable y «tomarse en serio la vida», buscando que sea auténtica y plena. (shrink)
ObjectiveTo provide insights on emergent ethical tensions experienced by mental health practitioners during system re-organisation, which is sufficiently grounded in empirical data at the local level to inform policy on recovery at institutional and provincial levels.MethodEthnographic methods using narrative and critical phenomenological resources over 24 months.FindingsEveryday ethical tensions emerged at the confluence of different experiences of time, for example, how a context of increasing pressure to decrease patients’ length of stay at the hospital challenged efforts to listen to and advocate (...) for what mattered to patients and maintain the integrity of interventions. In this context, practitioners drew on clinical language and that of personal recovery to strategically ‘push back’, ‘play with’ or ‘take back’ time.DiscussionExamining everyday practices through ethnographic methods can illuminate the everyday ethical tensions that arise when mental health professionals and psychiatrists grapple with, often competing, goods. Critical phenomenological resources can help expand the structural considerations in empirical ethics, excavate underground practices and raise questions about the conceptual categories undergirding normative ethics. Experiencing-with practitioners in clinical contexts as they encounter and creatively resolve ethical tensions also propose a normative ethics of possibility, to help bridge the gap between empirical and normative ethics.ConclusionFocus on the relationship between policy, temporal practices and ethics suggests a reconfiguration of time and re-imagination of ethics in institutional settings in ways that can ultimately benefit patients and professionals alike.
