Este trabajo muestra cómo una modificación en el sentido del término caracter adquirido llevó a rechazar la hipótesis de la herencia de esos caracteres. Se considerará el ejemplo del experimento llevado a cabo por Weismann que fue tomado como un caso paradigmático en los libros de textos y en la bibliografía especializada para refutar esa hipótesis. Ese diseño experimental fue aceptado por la comunidad como una refutación, a pesar de que los caracteres a los que hacía referencia no cumplían con (...) ninguna de las condiciones necesarias para poder ser considerado un carácter adquirido. Así, quedó establecida la premisa de que sólo las células germinales podían heredarse fundándose lo que se conoció como la barrera de Weismann. Este caso pretende poner en consideración cómo la enseñanza y reproducción de los términos científicos y de sus indicadores puede llevar a limitar el desarrollo de las teorías. Se concluye acerca de la necesidad de reflexionar sobre la manera en que se citan y enseñan las teorías científicas a fin de evitar barreras en el desarrollo de los campos disciplinares. (shrink)

In this article I will analyze whether the so-called Extended Evolutionary Synthesis represents a synthesis and an extension with respect to its predecessor, Modern Synthesis. It will be argued that the MS proposes an externalist approach to evolution while the EES considers it necessary to overcome the internalism/externalism dichotomy by proposing more integrative approaches. It will be concluded that the EES cannot be considered an extension of MS and that the appeal to that extension is related to sociological aspects and (...) the epistemic value of theoretical unification that was always present in biological evolutionary thinking.

La problemática adaptativa constituye un tema central para la teoría evolutiva. Uno de los principales cuestionamientos está dado por aquellos procesos que tradicionalmente se han considerado como adaptativos y que a la luz de la evidencia actual deben ser redefinidos. El estudio de la adaptación en el caso del parasitismo reviste especial importancia por sus aspectos epidemiológicos, ecológicos y evolutivos, además de su impacto en medicina evolutiva. El objetivo del presente trabajo es hacer un estudio de casos en cestodes con (...) el propósito de contrastar el grado de aplicación de la definición de adaptación propuesta por Dressino y discutir su viabilidad, limitaciones y alcances para el fenómeno parasitario. Se analizan numerosas definiciones y conceptos de adaptación y se advierte que muchas de ellas no cuentan con los requerimientos formales necesarios para su corroboración empírica. En base al análisis de casos de cestodes y teniendo en cuenta los conceptos de “interrelación de eslabones del ciclo biológico” y “potencialidad del fenómeno parasitario”, se propondrá el concepto de “concatenación de adaptaciones”. En razón de las particularidades adaptativas observadas en parásitos y de la inviabilidad de las definiciones de adaptación aplicadas a estos grupos, este nuevo concepto supone una multiplicidad de adaptaciones que se enlazan unas con otras y que la modificación de cualquiera de ellas tiene profundas consecuencias en las restantes.Adaptative issues constitute a central topic in evolutionary theory. One of the main questions concerns the processes that have traditionally been considered as adaptative and that should be redefined in the light of current evidence. The study of the adaptation in the case of parasitism was especially important for its epidemiological, ecological and evolutionary aspects, besides its impact on evolutionary medicine. The purpose of this work is a study of cases in cestodes in order to contrast the degree of application of the definition of adaptation proposed by Dressino and to discuss its feasibility, limitations and reaches for the phenomenon of parasites. A large number of definitions and concepts of adaptation is analyzed and it is observed that many of them do not fulfill the necessary formal requirements for their empiric corroboration. Based on the analysis of cases of cestodes and keeping in mind the concept of “interrelationship of links in the biological cycle” and “potential of the parasitic phenomenon”, we proposed the concept of “concatenation of adaptations”. Due to the adaptative particularities observed in parasites and the non feasibility of the definitions of adaptation applied to these groups, this new concept assumes that there is a multiplicity of adaptations that are linked to each other and that the modification of any one of them has profound consequences on the remaining adaptations.

The tragedy of old age is not that one is old, but that one is young.So begins Susana E. Sommer’s Según pasan los años: La vejez como un momento de la vida, in which she tackles, in an original way, the subject of aging. Sommer shows us that, although it is not always easy, aging does not have to be terrifying, and she tries to suggest how to cope with this aspect of life.In the introduction, Sommer provides an overview (...) of the issues she will discuss. A biologist, she devotes a chapter to various biological theories about aging, the evolutionary explanations that account for it, and numerous works that link the consequences of eating habits and lifestyles to aging.

Organized by the Mind and Life Institute, this discussion addresses some of the most troublesome questions that have driven a wedge between Western science and religion. Where Buddhism Meets Neuroscience resulted from meetings of the Dalai Lama and a group of eminent neuroscientists and psychiatrists. Is the mind an ephemeral side effect of the brain's physical processes? Are there forms of consciousness so subtle that science has not yet identified them? How does consciousness happen? The Dalai Lama's incisive, open-minded approach (...) both challenges and offers inspiration to Western scientists. The book consists primarily of dialogue and intense, frank conversations between the Dalai Lama and participants. Questions of perception, dualism, categories of consciousness, memory, dreams, the nature of mental illness, and the mind during and after death are all explored. (shrink)

In their target article, Mikhalevich & Powell (M&P) argue that we should extend moral protection to arthropods. In this commentary, we show that there are some unforeseen obstacles to applying the sort of individualistic welfare-based ethics that M&P have in mind to certain arthropods, namely, insects. These obstacles have to do with the fact that there are often many more individuals involved in our dealings with insects than our ethical theories anticipate, and also with the fact that, in some sense, (...) some insects count as more than an individual and, in another sense, they sometimes count as less than an individual.

Observations of animals engaging in apparently moral behavior have led academics and the public alike to ask whether morality is shared between humans and other animals. Some philosophers explicitly argue that morality is unique to humans, because moral agency requires capacities that are only demonstrated in our species. Other philosophers argue that some animals can participate in morality because they possess these capacities in a rudimentary form. Scientists have also joined the discussion, and their views are just as varied as (...) the philosophers’. Some research programs examine whether animals countenance specific human norms, such as fairness. Other research programs investigate the cognitive and affective capacities thought to be necessary for morality. There are two sets of concerns that can be raised by these debates. They sometimes suffer from there being no agreed upon theory of morality and no clear account of whether there is a demarcation between moral and social behavior; that is, they lack a proper philosophical foundation. They also sometimes suffer from there being disagreement about the psychological capacities evident in animals. Of these two sets of concerns—the nature of the moral and the scope of psychological capacities—we aim to take on only the second. In this chapter we defend the claim that animals have three sets of capacities that, on some views, are taken as necessary and foundational for moral judgment and action. These are capacities of care, capacities of autonomy, and normative capacities. Care, we argue, is widely found among social animals. Autonomy and normativity are more recent topics of empirical investigation, so while there is less evidence of these capacities at this point in our developing scientific knowledge, the current data is strongly suggestive.

In this paper, we argue that scientists working on the animal morality debate have been operating with a narrow view of morality that prematurely limits the variety of moral practices that animals may be capable of. We show how this bias can be partially corrected by paying more attention to the touch behaviours of animals. We argue that a careful examination of the ways in which animals engage in and navigate touch interactions can shed new light on current debates on (...) animal morality, like the study of consolation behaviour, while also revealing further forms that animal morality may take and that have been neglected so far, like capacities of tolerance or trust. This defence is structured as an analysis of the three main functions of touch: the discriminative function, the affiliative function, and the vigilance function. (shrink)

DERECHO DE RESPUESTA COMO FORMADOR DE OPINIÓN PÚBLICA: La jurisprudencia norteamericana y su relación con la argentina.

El presente texto propone una lectura de A Feminist Theory of Refusal asumiendo como propia la doble clave teórica y política que el libro sostiene. En la primera parte se resumen los puntos centrales de Honig sobre el tipo de complejización e impurificación de la teoría vigente que el drama Las Bacantes de Eurípides habilitaría, y sobre la importancia de esta nueva conceptualización para la práctica política feminista. A continuación se formulan algunos interrogantes respecto del proceso histórico en el cual (...) este concepto deviene protagónico para la teoría política crítica y se señalan posibles limitaciones del mismo a la hora de describir el tipo de desafíos que enfrentan las luchas emancipatorias e igualitarias emprendidas por el movimiento feminista en Argentina.

So far little are the studies that have focussed on exploring school principals’ self-conception of their distributed leadership competencies in relation to their managerial and teaching experience. To do so, an exploratory research was carried out with a sample of 163 pre-service and in-service school principals studying a Master’s programme in School Management, Innovation and Leadership at a Spanish University. Data were obtained by using an Ad hoc questionnaire of 7 units of competence and 5 proficiency levels for each unit, (...) based on an existing rubric to analyse students’ self-conception of their development of leadership competencies. The findings of this preliminary study show statistically significant differences in the self-perception in all dimensions associated to Managerial Experience and Teaching Experience in schools. Study participants with ME showed statistically higher levels than those who had non-ME in four of seven dimensions: lead the school organisation, address the needs of the students, manage the organisation of the school organisation, and manage administrative work. Similar results were obtained in relation to TE versus non-TE were statistically significant differences are found in six dimensions: manage pedagogical and didactic resources, attend to the needs of students, manage didactic strategies, manage the organisation of the school organisation, manage the link between the school organisation and the community, and lead the school organisation. This study shows the importance of teaching and professional experience to acquire leadership competencies in education, therefore the school principal should also be a teacher. This preliminary study provides insights into the relevance of providing pre-service or in-service school principals with training and professional development programmes on sustainability distributed leadership that enable them to genuinely engage the school community, develop innovative pedagogies and lead the process of change toward building more sustainable schools.

In recent years, some ethicists have defended that we should genetically engineer farmed animals to diminish or eliminate their capacity to experience negative affective states, a process known as disenhancement that would, according to these authors, result in a situation that is better than the status quo. While we agree with this overall assessment, we believe that it is a mistake to defend disenhancement as a good solution to farmed animals’ plight. This is because disenhancement entails some generally unseen harms (...) that arise from the fact that negative affective states, despite feeling bad, support the access to a number of intrinsic goods, such as individuality, social relationships, meaning, and political participation. Though farmed animals currently have few opportunities to enjoy these goods, we argue that this is a reason to change the environment in which they are kept, not the animals. If we truly care about improving farmed animals’ lives, we should aim to enrich their environment, rather than impoverish their mental lives. (shrink)

This highly acclaimed volume brings together some of the world's foremost historians of ideas to consider Machiavelli's political thought in the larger context of the European republican tradition, and the image of Machiavelli held by other republicans. An international team of scholars from a variety of disciplinary backgrounds (notably law, philosophy, history and the history of political thought) explore both the immediate Florentine context in which Machiavelli wrote, and the republican legacy to which he contributed.

This eloquent, impassioned manifesto is possibly the most important message the Dalai Lama can give us about the future of our world. It's his rallying cry, full of solutions for our chaotic, aggressive, divided times: no less than a call for revolution. Are we ready to hear it? Are we ready to act?"--Publisher annotation.

Modern management reporting on its company''s performance is influenced by individuals ethical considerations. Stakeholders philosophies have continued to change over the last 75 years affecting reporting systems for companies reporting information internally and externally. These fundamental changes in philosophy have affected how information is conveyed. We are not claiming that only one philosophical viewpoint dominates companies reporting practices, but there does appear to be a changing trend of philosophies building on one another. We use resource dependence theory in relationship to (...) a decision-making model to explain changing stakeholders positions over time. This paper argues that six dominant philosophical theories have influenced the way individuals and organizations report financial and other information. Further, these philosophies then are depicted in a model that helps us to understand what influences companies to present themselves to the outside world. A vignette is used to depict changing philosophical views for several companies management report over 75 years. (shrink)

This paper discusses the potential of the notions of reification and consensualization as developed by the theory of social representations as analytical tools for addressing the communication between the lay and scientific spheres. Social Representations Theory started by offering an over-sharp distinction between the reified and the consensual universes of which science and common sense, respectively, were presented as paradigmatic. This paper, however, suggests that the notions of consensual and reified can be considered as describing two distinct communicative formats: reification (...) implying the use of arguments which establish prescriptions for representations and action, and consensualization relying on arguments which recognize the heterogeneity of representation and action. We illustrate this proposal through the analysis of a case in which the expert and the lay spheres of a Lisbon neighborhood opposed each other regarding the new laws of public participation in community matters. This analysis showed how reification and consensualization can be used as discursive formats by both spheres. The implications of the use of reification and consensualization and how they may depend on several power resources and have different impacts on social change are discussed. (shrink)

Historically, as well as more recently, women's emancipation has been seen in two ways: sometimes as the `right to be equal' and sometimes as the `right to be different'. These views have often overlapped and interacted: in a variety of guises they have played an important role in both the development of ideas about women and feminism, and the works of political thinkers by no means primarily concerned with women's liberation. The chapters of this book deal primarily with the meaning (...) and use of these two concepts in the context of gender relations, but also draw attention to their place in the understanding and analysis of other human relationships.

Inspired by Farshad Zahedi’s audiovisual essay The Petrified Object and the Poetics of Time in Cinema, this article briefly presents three philosophical approaches to cinema’s ways of expressing time – as articulated by Bergson, Tarkovsky, and Deleuze – and questions how absolute time and chronological time are brought to a state of crisis by this modern form of art.

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)
