All the biological membranes contain oxidoreduction systems actively involved in their bioenergetics. Plasma membrane redox systems seem to be ubiquitous and they have been related to several important functions, including not only their role in cell bioenergetics, but also in cell defense through the generation of reactive oxygen species, in iron uptake, in the control of cell growth and proliferation and in signal transduction. In the last few years, an increasing number of mechanistic and molecular studies have deeply widened our (...) knowledge on the function of these plasma membrane redox systems. The aim of this review is to summarize what is currently known about the components and physiological roles of these systems. (shrink)

The empirical relationship between a firm’s social performance and its financial performance is still not well established in the literature. Despite more than 30 years of research and more than 100 empirical studies on the issue, the results are still mixed. We argue that the heterogeneous results found in previous studies are not due exclusively to problems related with the measurement instruments or the samples used. Instead, we posit that a more fundamental problem related with the endogeneity of social strategic (...) decisions could be driving most of the empirical findings. We show that, using a panel data of 658 firms from 1991 to 2005, how some of the results found in previous research change, and some are even reversed when endogeneity is properly taken into account.

Corporate governance (CG) can be seen to operate through a 'double agency' relationship: one between the shareholders and corporate management, and another between the corporate management and the firm's employees. The CG and labour management of firms are closely related. A particularly productive way to study how CG affects and is affected by the employment relationship has been to compare CG across countries. The contributions of this paper to that literature are threefold. (1) An integration of aspects of the labour (...) management literature in the CG debate. (2) Based on a sample of about 1000 firms from 31 countries, we find evidence of complementarities between the CG and the labour management of firms. Extreme cases, in general, outperform mixed cases. (3) Firm differences within countries are more important than scholars have assumed so far. We present the results of the study and implications for future research and for practice. (shrink)

According to the dual inheritance theory, cultural learning in our species is a biased and highly efficient process of transmitting cultural traits. Here we define a model of cultural learning where social learning is integrated as a complementary element that facilitates the discovery of a specific behavior by an apprentice, and not as a mechanism that works in opposition to individual learning. In that context, we propose that the emergence of the ability to approve or disapprove of offspring behavior, orienting (...) their learning, transformed primate social learning into a cultural transmission system, like that which characterizes our species. Assessor teaching facilitates the replication and/or reconstruction of behaviors that are difficult to imitate and helps to determine which behaviors should be imitated. We also explore the form in which assessor teaching has conditioned the evolution of our abilities to develop cultures in the hominin line, converting us into individuals equipped with what we call a suadens psychology. Our main point is to defend the hypothesis that suadens psychology determines the stability and dynamics that affect the trajectories of many cultural characters. We compare our proposal with other theories about cultural evolution, specifically with dual inheritance theory and cultural attraction theory. (shrink)

Humans have developed the capacity to approve or disapprove of the behavior of their children and of unrelated individuals. The ability to approve or disapprove transformed social learning into a system of cumulative cultural inheritance, because it increased the reliability of cultural transmission. Moreover, people can transmit their behavioral experiences (regarding what can and cannot be done) to their offspring, thereby avoiding the costs of a laborious, and sometimes dangerous, evaluation of different cultural alternatives. Our thesis is that, during ontogeny, (...) the evaluative communication (approval/disapproval) between parents and offspring is substituted by other evaluative communications among peers, like individuals of the same generation. Each person belongs to a reference social group with individuals that interact more intensively. Humans have developed psychological mechanisms that enable cultural transmission by being receptive to parental advice as well as their reference social group. The selective pressure that promoted these new evaluative interactions arose to facilitate the establishment of efficient cooperative relationships. In short, the social control of behavior is essential to understand human cultural transmission. (shrink)

This paper presents the hypothesis that linguistic capacity evolved through the action of natural selection as an instrument which increased the efficiency of the cultural transmission system of early hominids. We suggest that during the early stages of hominization, hominid social learning, based on indirect social learning mechanisms and true imitation, came to constitute cumulative cultural transmission based on true imitation and the approval or disapproval of the learned behaviour of offspring. A key factor for this transformation was the development (...) of a conceptual capacity for categorizing learned behaviour in value terms - positive or negative, good or bad. We believe that some hominids developed this capacity for categorizing behaviour, and such an ability allowed them to approve or disapprove of their offsprings- learned behaviour. With such an ability, hominids were favoured, as they could transmit to their offspring all their behavioural experience about what can and cannot be done. This capacity triggered a cultural transmission system similar to the human one, though pre-linguistic. We suggest that the adaptive advantage provided by this new system of social learning generated a selection pressure in favour of the development of a linguistic capacity allowing children to better understand the new kind of evaluative information received from parents.

Uno de los principales problemas de la filosofía de la psicopatología contemporánea consiste en definir qué tipo de estados mentales son aquellos que denominamos delirantes. A esto se le ha denominado el “problema tipológico de los delirios”.

(...) Para examinar el debate, el artículo presentará las principales características de ambas posiciones y sus fundamentos. Después, examinaremos los principales argumentos esgrimidos contra el doxasticismo y las respuestas y contraargumentos por parte de las alternativas doxásticas.

We consider the evolutionary scheme of morality proposed by Tomasello to defend the idea that the ability to orient the learning of offspring using signs of approval/disapproval could be a decisive and necessary step in the evolution of human morality. Those basic forms of intentional evaluative feedback, something we have called assessor teaching, allow parents to transmit their accumulated experience to their children, both about the behaviors that should be learned as well as how they should be copied. The rationale (...) underlying this process is as follows: if a behavior is approved, then it is good; if it is disapproved, then it is bad. The evaluative guidance on how to behave most probably spread among peers in situations of mutual benefit, such as cooperative child rearing. We argue that our hominin ancestors provided with this capacity for assessor teaching were ideally positioned to develop the two specifically human levels of morality proposed by Tomasello: the morality of fairness and the morality of justice. Assessor teaching could have facilitated the genesis of rudimentary codes of behavior tied with the need to agree about how to behave to succeed in joint cooperative activities. Moreover, learning through assessor teaching provides a plausible explanation for the origin of the objectivist and prescriptive dimensions of human morality. First, we emphasize that individuals feel that they evaluate the behavior of others objectively to guide their learning, and, second, we underline the imperative intention that any moral manifestation possesses.

The central idea defended here is that ethical judgements are the product of the adaptive advantage provided by the conceptual capacity to categorise learned behaviour. In the same way that evolution of learning required the presence of value-laden brain structures that guide behaviour in the organism, we propose that the evolution of social learning and the development of human culture required the emergence of a new value system — the 'conceptual capacity to categorise'. This capacity is defined as the ability (...) to categorise one's own behaviour through a conceptual value code — 'favourable/unfavourable' or 'good/bad'. The conceptual capacity to categorise learned behaviour as good or bad was evolutionary successful because it transformed a system of rudimentary cultural transmission based on imitation into a system of efficient and biased cultural heredity based on teaching. Conceptual categorisation allowed the acquisition, through social learning, of adaptive information about behaviour, originating in/from the value-laden brain systems which control learning, without resorting to individual experience. We also suggest that the conceptual capacity to categorise conditioned the evolution of the human intelligence and that the ethical capacity arose as a by-product of both high intelligence and the ability to make evaluations of learned behaviour.

ResumenEste artículo propone una idea de intervención e institución que se entrelace en lo social a través del concepto de contagio como elemento filosófico articulador. En primer lugar, se establece un marco teórico-filosófico para pensar la vida como una ontología social del contagio, que permita habitar un pensar relacional etológico que se abra a otros modos de existencia. Desde este marco, los hallazgos perfilan la relación intervención-institución desde la sensibilidad que evoca esta forma distinta de intervención en lo social, disponiendo (...) de otros modos las variaciones de la institución y sus procesos de instituir el campo social. Se concluye discutiendo la relación entre intervención y sus capacidades transformativas como componente metódico y epistemológico distinto que trae consigo un fuerte potencial político y ético. Al multiplicar los modos de ser y los procesos de subjetivación se abren prácticas humanas y más-que-humanas, instituyendo otros modos de hacer-y-pensar toda intervención del presente.Palabras clave: institución; intervención; contagio; formas de vida; cartografías.

Spain’s Roma community has its own cultural and moral values. These values influence the way in which end-of-life decision-making is confronted. The objective of this study was to explore the perspective of Roma women on end-of-life decision-making. It was a qualitative study involving thirty-three Roma women belonging to groups for training and social development in two municipalities. We brought together five focus groups between February and December 2012. Six mediators each recruited five to six participants. We considered age and care (...) role to be the variables that can have the most influence on opinion regarding end-of-life decision-making. We considered the discussion saturated when the ideas expressed were repeated. Data analysis was carried out according to five steps: describing, organizing, connecting, corroborating/legitimating, and representing the account. The main ideas gleaned from the data were as follows: the important role of the family in end-of-life care, especially the role of women; the large influence of community opinion over personal or family decisions, typical of closed societies; the different preferences women had for themselves compared to that for others regarding desired end-of-life care; unawareness or rejection of advance directives. Roma women wish for their healthcare preferences to be taken into account, but “not in writing.” The study concluded that the success of end-of-life healthcare in Roma families and of their involvement in the making of healthcare decisions depends upon considering and respecting their idiosyncrasy.

If Unamuno had been able to choose how to be remembered, he would have wanted him to be a poet. This book wants to do justice to that happy possibility. But above all because Unamuno was a poet in the highest sense: he was while writing the same essay as a novel, or theater, letter or verse, and he was also a poet when he passionately lived all the facets of his intense existence. His intellectual work was poetic and his (...) personal relationships, as well as his political activity, also responded to that peculiar Unamunian aesthetic in which the vital horizon is inescapably confused with the tasks of thought." --Translated from back cover.

RESUMO O presente artigo parte de várias considerações de Bakhtin a respeito do discurso romanesco a fim de compreender alguns aspectos discursivos do Dom Quixote, de Miguel de Cervantes. Procede-se, então, a uma comparação com o discurso de outra obra que reproduz parcialmente o Dom Quixote: o conto Pierre Menard, autor do Quixote, de Jorge Luis Borges. Por fim, discute-se brevemente o problema da quase ausência do Dom Quixote nas discussões de Bakhtin sobre o romance, apresentando-se a hipótese de (...) Walter Reed de que, tal como no conto de Borges, a própria teoria bakhtiniana também reproduz parcialmente o peculiar pensamento do Quixote. ABSTRACT This article discusses several of Bakhtin’s concepts regarding discourse in the novel genre as a way to understand some discursive aspects of Miguel de Cervantes’ Dom Quixote. We then proceed to a comparison with the discourse in another literary work that partially reproduces Dom Quixote: the short story “Pierre Menard, Author of the Quixote,” by Jorge Luis Borges. Finally, we briefly discuss the problem of Dom Quixote’s almost absence in Bakhtin’s work about the novel genre, while presenting the hypothesis by Walter Reed that, as in Borges’ short story, Bakhtin’s theory itself also partially reproduces the Quixote’s particular way of thinking.

Este artículo pretende mostrar la lectura política que hace Miguel Abensour de Lévinas cuando analiza el sentido del eje conceptual levinasiano de la responsabilidad-para-elotro y sus vinculaciones ético-políticas. Así, podemos redescubrir la irreductibilidad de lo político como una dimensión que requiere de lo humano, todo esto bajo el lema de la extravagante hipótesis. Lo humano –a la luz de Lévinas y en lo cual Abensour se ancla– instala su propia irreductibilidad que hace renovar lo político y deja aparecer una (...) filosofía política crítica que quiere pensar de otro modo el Estado y la justicia. (shrink)

En varios pasajes de la obra de Lévinas vemos que su manera de presentarse frente a lo político es ambigua. O bien, resulta mejor decir que solo en apariencia el "objeto" de lo político en sus reflexiones sobre la justicia y el Estado resultan claras; hay una suerte de equívoco que vale la pena precisar y distinguir. Así, el objetivo central de este trabajo es describir dos momentos políticos en Lévinas leídos en clave Estado, como una figura posible de la (...) política; desentrañamos así la trama anti-política en tanto crítica política al Estado, para llegar a la trama del Estado justo e igualitario, lo que abre nuevas puertas para pensar lo político. A partir de esta descripción reflexionamos, por un lado, una postura crítica frente a las ideas sobre el Estado de Lévinas desde las vinculaciones ético-políticas que hace, tal como la de Alberto Sucasas. Y por otro, en contraposición a éstas, las interesantes y extravagantes lecturas que hace Miguel Abensour de Lévinas creyendo que las relaciones ético-políticas levinasianas aportan a renovar críticamente una nueva figura de Estado dejando el terreno político y estatal abierto a nuevas reflexiones. In several passages of Levinas' work we see that his way of presenting the political front is ambiguous. Or, more precisely, that the "object" of the political in his reflections about justice and the State is only apparently clear; there is a sort of equivocalness that is worth clarifying and distinguishing. The aim of this article is to describe two political moments in Levinas, read in terms of the State as a possible figure in politics. We thus unravel an anti-political theme which is critical of the politics of the State, in order to reach a theme of a State that is just and egalitarian. This opens up new territory from which to think of the political. One critique of Levinas' ideas of the State in terms of its ethical-political linkages is that put forth by Alberto Sucasas. A second contrasting critique is the interesting and extravagant reading of Miguel Abensour, in which Levinasian ethical-political relationships lead to a critical renewal of a new figure of the State, leaving the political and state terrain open to new reflections.

El propósito de este libro es de examinar cuales fueron los órdenes epistemológicos, las prácticas discursivas y los mecanismos disciplinarios que hicieron posible en el siglo XX la construcción de un objeto de conocimiento llamado "Latinoamérica", y de una serie de saberes filosóficos sobre "lo latinoamericano". El autor realiza un ejercicio deconstructivo de aquellas narrativas que, con base a la creación de identidades homogéneas, buscaron presentar a Latinoamérica como lo "otro" de la modernidad occidental, e incluso como el continente llamado (...) a mostrar un camino nuevo de liberación para toda la humanidad. A través de un diálogo con pensadores como Foucault, Said, Rama, Lyotard, Mignolo y Spivak, el autor muestra que los principales temas, registros y motivos esgrimidos a favor de una "exterioridad" latinoamericana con respecto a la modernidad, son en realidad discursos pertenecientes a un orden moderno del saber.

To advance the task of designing robots capable of performing collective tasks with humans, studies in human–robot interaction often turn to psychology, philosophy of mind and neuroscience for inspiration. In the same vein, this chapter explores how the notion of recognition and commitment can help confront some of the current problems in addressing robot-human interaction in joint tasks. First, we argue that joint actions require mutual recognition, which cannot be established without the attribution and maintenance of commitments. Second, we argue (...) that commitments require affective states such as social motivations or shared emotions. Finally, we conclude by assessing three possible proposals for how social robotics could implement an architecture of commitments by taking such an affective components into consideration. (shrink)

This paper presents an ontological perspective that enables evaluating the effectiveness of business models from an integrative worldview. Different groups’ fragmented and reductionist views on this topic create a dichotomy that makes it difficult to compare and analyze them in practice. Such groups use different values for some components, which may result in neglecting others and their interrelationship. This study discusses a functional characteristic of business models that academia still needs to address. It explores new frontiers in the field, such (...) as business models for networks, sustainability, and their practical evaluation. To achieve an integrative ontology and avoid focusing on specific constructs or systems at the expense of others, we draw upon the theory of worldviews from Wilhelm Dilthey, reformational philosophy, and Herman Dooyeweerd’s theory of modal aspects. Society should move beyond dualistic thinking and embrace practical and applicable solutions. To help companies develop effective models, we introduce a new business model framework based on an integrative worldview that enables comparisons and evaluations of companies in practice. Creating competitive advantages and value appropriations synergizes with essential aspects of reformational philosophy. Analyzing and interrelating such elements are fundamental to understanding the real applied value of business models. (shrink)

Lejos de nuestros modelos, la palabra desorden suele designar la riada anónima del exterior. Querría señalar la fuerza ciega de una corriente humana y terrenal, impetuosamente aleatoria, de la que debemos protegernos. Pero éste no es un libro de ética al estilo usual. No opera con la contraposición del bien al mal, no busca un conjunto de prescripciones para una vida mejor ni una idea del deber que guíe la acción. No intenta que los hombres aprendan a conducirse en términos (...) supuestamente morales, sino que cada uno asuma su indescifrable signo natal y le dé una forma de vida. El vínculo entre ética y alegría, entre moral y fuerza, ha sido peligrosamente olvidado. La disciplina no es reclamada por las señas externas de la organización, sino por el desarrollo interior de la potencia. Este libro intenta actualizar la vieja certeza, oriental y occidental, de que las contingencias externas acaecen siempre con un orden oculto, remotamente inteligible. Según tal experiencia, el pensamiento no es en primer lugar un acto reflexivo que pueda o no realizarse, sino la turbulencia secreta de cualquier presencia material, por apacible que parezca. Lo mismo es ser y pensar, se afirma ya antes de Platón. Se trata de una experiencia vertiginosa y a la vez común, admitida en la más llana –aunque no siempre expresable– sabiduría popular. Si aquí se tiene la pretensión de defenderla, de modo suficientemente comprensible, es por la intención de mostrarla en la más cotidiana y banal actualidad. (shrink)
