The origin of chordates and the consequent genesis of vertebrates were major events in natural history. The amphioxus (lancelet) is now recognised as the closest extant relative to the stem chordate and is the only living invertebrate that retains a vertebrate‐like development and body plan through its lifespan, despite more than 500 million years of independent evolution from the stem vertebrate. The inspiring data coming from its recently sequenced genome confirms that amphioxus has a prototypical chordate genome with respect to (...) gene content and structure, and even chromosomal organisation. Pushed by joint efforts of amphioxus researchers, amphioxus is now entering a new era, namely its maturation as a laboratory model, through the availability of a large amount of molecular data and the advent of experimental manipulation of the embryo. These two facts may well serve to illuminate the hidden secrets of the genetic changes that generated, among other vertebrates, ourselves. (shrink)

Los Estados confederados proyectan la existencia de un doble sistema normativo: federal y local. Esto provoca el surgimiento de colisiones y contradicciones entre ambos sistemas, lo que se pensaría debería ser resuelto por el derecho internacional, atendiendo el principio de subsidiariedad, no obstante, esto no siempre es así, ya sea porque el derecho internacional no regule ese caso concreto o bien, porque el Estado en cuestión no haya otorgado su consentimiento y la respuesta no le sea vinculante. Estas reflexiones invitan (...) a contrastar la naturaleza de las normas del derecho local y del derecho internacional, pues mientras que las primeras son asociativas, dado que no necesariamente requieren ser consentidas para ser vinculantes, las segundas, aparentemente, sí requieren el consentimiento de los Estados para que tengan efectos vinculantes. En este artículo pretendemos postular una posible solución al problema del conflicto entre los distintos órdenes normativos, partiendo desde una postura cuasi-voluntarista. Las obligaciones cuasi-voluntarias son aquellas que no surgen del consentimiento, pero tampoco completamente de los roles que tienen los Estados en el sistema internacional. Estas obligaciones nacen en el núcleo de grupos dominantes, a los que llamaremos grupos autocontenidos en el ámbito internacional, que tienen como rol la creación y socialización de las normas y obligaciones de derecho internacional, logrando que los otros grupos simplemente las sigan como si tuvieran un deber de hacerlo. Para ello, servirá como referencia el análisis del caso de las disimiles normas migratorias entre California y Texas dentro de Estados Unidos. (shrink)

This research presents an analysis of the learning strategies employed by students during confinement due to Covid-19 in the year 2021. The study sample consisted of 200 students from the Licenciado Benito Juárez García high school of the morning shift of the Benemérita Universidad Autónoma de Puebla. A survey was applied to measure the degree of satisfaction in relation to their use and impact on the acquisition of knowledge, allowing them to be more self-taught.The results show that the hypothesis (...) was partially fulfilled, since practice and organization are the learning strategies that most supported them in learning.

In line with its institutional commitments and in order to strengthen the relevance of its business education program in addressing the persistent social challenges facing the Philippines, Mission University revised its Master of Business Administration curriculum in 2012. A core change in the curriculum was the incorporation of action research training and the requirement for graduation of implementing and defending an action research project. The introduction of action research, which is based on critical realist philosophy of science, was intended to (...) enable the university’s MBA graduates to become reflexive and humanistic agents of change in their work contexts through the application of observation, critical reflection, collaborative analysis and action and scholarly skills. The implementation of the action research requirement is beginning to yield positive results based on the types of projects implemented by the students and their resulting sense of efficacy in the workplace. Challenges in implementation include the need to further hone student skills in pursuing more emancipatory projects and the need to further orient faculty in the critical realist philosophy underlying action research, as distinct from traditional positivism.

This paper deals with the interpretation and distribution of universal Free Choice (FC) items, such as English FC any or Spanish cualquiera. Crosslinguistically, universal FC items can be characterized as follows. First, they have a restricted distribution. Second, they express freedom of choice: the sentence You can take any card conveys the information that the addressee is free to pick whichever card she chooses. Under standard assumptions, the truth conditions of sentences like You can take any card are taken to (...) be captured by formalizations in which a universal quantifier ranging over individuals has wide scope over the possibility modal. The crucial observation that informs the account in this paper is that this type of formalization cannot capture the freedom of choice component. I will argue that in order to derive the right interaction between possibility modals and FC items, we need to add an exclusiveness condition to the standard wide scope paraphrases. The same proposal that guarantees freedom of choice will automatically account for the distribution restrictions of FC items. The formal implementation of this proposal is cast in the Hamblin semantics proposed in Kratzer and Shimoyama (Indeterminate phrases: The view from Japanese, 2002). (shrink)

Este trabajo quiere responder a la demanda de quienes buscan una introducción breve pero significativa a las reflexiones de Joseph Ratzinger sobre la identidad histórica de Europa. Se trata de un estudio que, desde la perspectiva del teólogo alemán, realiza un somero itinerario por la historia político-espiritual de Europa, subrayando la cesura que constituyó el siglo XX, y que finaliza con algunas propuestas para construir una Europa con futuro. Entre éstas no conviene olvidar la luz que proviene de los extraños (...) destellos de revelación, sugiriendo un futuro ensayo de teología de la historia. (shrink)

This practical-theological study aims to develop a contextual theology in the areas of business and government that will aid a successful intervention by the church in diminishing the corrupt practices prevalent in South Africa. It seeks to prove that corruption is a major factor in causing the delays experienced in the implementation of service delivery, and that this is causing much anger and increasing disillusionment with the present system of democratic government. At the moment the church has a window of (...) opportunity for this intervention to take place, since many of those responsible for supporting, organising and implementing service delivery, both in government and industry, worship regularly, as committed members, in local Christian congregations. A modified application of the Asset-Based Community Development (ABCD) approach using focus groups is suggested as both a tool for intervention and for further research. (shrink)

Across languages, we find indefinites that overtly mark a speaker’s lack of knowledge: they signal that the speaker is unable to give any further information about who or what satisfies her existential claim (Becker, 1999; Haspelmath, 1997). From now on, we will refer to the marking of the speaker’s lack of knowledge as an epistemic effect and to the indefinites that induce epistemic effects as epistemic indefinites.

El descubrimiento del Nuevo Mundo hace del nuestro el Viejo, metaforizándose en parejas de opuestos: nuevo/viejo, moderno/anticuado. Reivindicando invención y novedad, su modernidad contra el orden antiguo, el culto barroco de lo nuevo estriba en una nueva vivencia del tiempo. La revolución técnica del nuevo espejo plano y del más fiable reloj, hace cobrar mayor o mejor conciencia de sí, pasando de un tiempo sin cuenta a un tiempo contado y atestiguado en reflejo y edad. Moda del autorretrato: comparación angustiosa (...) o consoladora con el otro, cuidado de sí y cuidándose de los demás. Visión y aversión de los ancianos que denunciara Rousseau al final del Barroco: el sentimiento del tiempo hace sentir la injusticia de una sociedad patriarcal al joven, socialmente subyugado al mayor todopoderoso, que controla hasta su casamiento con abusivas leyes civiles que desvían y desvirtúan las libertades canónicas. Conflicto generacional, pues, arqueología de la modernidad. (shrink)

Se examina una cuestión fundamental y poco estudiada de la teología política: la relación entre la defensa de la inmortalidad del alma y el mantenimiento del orden público. Se realiza un recorrido histórico por autores como Pietro Pomponazzi y Tomás Moro, que aceptan motivos políticos para defenderla, y David Hume, quien considera que no existe ningún motivo político para mantener dicha relación. Por último, se analizan los argumentos esgrimidos para mostrar que su eficacia está condicionada por la situación histórica.

Pegaso Zorokin es una novela experimental que fue publicada en 2012 en cinco volúmenes de la revista digital [Radiador] Magazine. Está compuesta por veintitrés capítulos sin aparente conexión entre ellos. Esta estructura complica una lectura global y pone en crisis la idea de novela. Sin embargo, es posible encontrar continuidad dentro de los fragmentos si se atiende a los puentes hipertextuales dentro del texto. Estas conexiones logran la unidad buscada. La conformación de la novela es muy similar a la de (...) cualquier red social digital. El objetivo de este artículo es explicar este funcionamiento dinámico. El trabajo analítico fue realizado bajo un método semiótico que involucra los conceptos semiósfera y persona semiótica de Yuri Lotman; hipertextualidad de Gerard Genette y propagabilidad de Gabrielle Marino. El análisis fue aplicado a tres de las cinco entregas de la novela de Arana, demostrando que el texto está compuesto por una red interna cohesionadora. (shrink)

This paper is a response to Haze’s brief argument for the falsity of the theory that instantial terms refer arbitrarily, proposed by Breckenridge and Magidor in 2012. In this paper, I characterise instantial terms and outline the theory of arbitrary reference; then I reconstruct Haze’s argument and contend that it fails in its purpose. Haze’s argument is supposed to be a _reductio ad absurdum:_ according to Haze, it proves that a contradiction follows from the most basic tenets of the theory (...) of arbitrary reference. I will argue, however, that the contradiction in question follows not from these tenets, but from the surreptitious use that Haze makes of a self-referential expression. I conclude, consequently, that Haze’s argument is nothing more than an illustration of the well-known fact that self-referential expressions produce paradoxical results. (shrink)

Supervenience is one of the 'hot discoveries' of analytic philosophy, and this collection of essays on the topic represents an examination of it and its application to major areas of philosophy. The interest in supervenience has much to do with the flexibility of the concept. To say that x supervenes on y indicates a degree of dependence without committing one to the view that x can be reduced to y. Thus supervenience is a relationship that has the potential of replacing (...) the traditional notion of dependence, while performing at least part of the function reductive relationships were supposed to fulfil. Moreover, since it is a topic-neutral concept, supervenience has a wide range of applicability. (shrink)

There are compelling reasons to believe that musical works are abstract. However, this hypothesis conflicts with the platitude that musical works are appreciated by means of audition: the things that enter our ear canals and make our eardrums vibrate must be concrete, so how can musical works be listened to if they are abstract? This question constitutes the audibility problem. In this paper, I assess Julian Dodd’s elaborate attempt to solve it, and contend that Dodd’s attempt is unsuccessful. Then I (...) discuss what I take to be the ideal response to the audibility problem, and show that it ultimately fails. I contend, consequently, that the project of construing musical works as audible is disheartening. Accordingly, in my last section, I will argue the audibility problem may be satisfactorily resolved without ascribing audibility to musical works. (shrink)

The concept of truth arguably plays a central role in many areas of philosophical theorizing. Yet, what seems to be one of the most fundamental principles governing that concept, i.e. the equivalence between P and , is inconsistent in full classical logic, as shown by the semantic paradoxes. I propose a new solution to those paradoxes, based on a principled revision of classical logic. Technically, the key idea consists in the rejection of the unrestricted validity of the structural principle of (...) contraction. I first motivate philosophically this idea with the metaphysical picture of the states-of-affairs expressed by paradoxical sentences as being distinctively . I then proceed to demonstrate that the theory of truth resulting from this metaphysical picture is, in many philosophically interesting respects, surprisingly stronger than most other theories of truth endorsing the equivalence between P and (for example, the theory vindicates the validity of the traditional laws of excluded middle and of non-contradiction, and also vindicates the traditional constraint of truth preservation on logical consequence). I conclude by proving a cutelimination theorem that shows the consistency of the theory. (shrink)

Dentro de la sociología francesa actual, Gilles Lipovetsky se ha convertido de forma paulatina en uno de los sociólogos con mayor proyección internacional, con sus finos análisis sobre las sociedades postmodernas. En este artículo se plantea una revisión crítica de las principales líneas argumentativas que expone el autor francés. El objetivo es el de reflexionar sobre las limitaciones de su aproximación a los conceptos de postmodernidad, hipermodernidad, y consumo.

El presente artículo se centra en destacar el modo en que Schelling aparece en la obra de Deleuze como un eslabón que permite vincular la reacción anticartesiana de Spinoza y Leibniz (reivindicadora de la dimensión apetitiva de la naturaleza) con la propia actitud antihegeliana de Deleuze. El giro voluntarista que Schelling imprime a la filosofía es igualmente prolongado por Deleuze y Guattari cuando establecen la esquizofrenia como inconsciente ontológico libidinar por el que circulan libremente las intensidades deseantes. Del mismo modo, (...) el empirismo trascendental de Deleuze toma impulso en la concepción schellingniana del ser como In-diferencia entre lo subjetivo y lo objetivo, anterior a todo fundamento o dualidad.

El presente trabajo procura analizar brevemente el concepto de “humus” trágico que supo transmitir Ortega –conscientemente o no-, a su discipulado, durante la conocida Escuela de Madrid. Para ello, y en segundo lugar, sostenemos que se puede desvelar este “humus” orteguiano desde las ideas de Hayden White. En tercer lugar, proponemos cómo se desplegaron dichas ideas orteguianas en María Zambrano y en José Gaos, y sostenemos que lo hicieron desde sus concepciones sobre la razón poética y cierta gigantomaquia de la (...) historia –respectivamente-, las cuales no sólo reflejaron fielmente dichas ideas sino que, además, dieron un paso más allá de la propuesta orteguiana. Finamente, intentaremos poner en evidencia cuáles son las características zambranianas y gaosianas de dicha concepción trágica de la filosofía, las cuales irán mucho más allá del racionalismo europeo tradicionalista.

Confidentiality is a central bioethical principle governing the provider–patient relationship. Dating back to Hippocrates, new laws have interpreted it for the age of precision medicine and electronic medical records. This is where the discussion of privacy and technology often ends in the scientific health literature when Internet-related technologies have made privacy a much more complex challenge with broad psychological and clinical implications. Beyond the recognised moral duty to protect patients’ health information, clinicians should now advocate a basic right to privacy (...) as a means to safeguard psychological health. The article reviews empirical research into the functions of privacy, the implications for psychological development and the resigned sentiment taking hold regarding the ability to control personal data. The article concludes with a call for legislative, educational and research steps to readjust the equilibrium between the individual and ‘Big Data’. (shrink)

This article contributes to the literature on national varieties of socially responsible investment (SRI) by demonstrating how Scandinavian SRI developed from the 60s and onwards. Combining findings on Scandinavian SRI with insights from previous research and institutional theory, the article accounts for the role of changes in societal values and norms, the mechanisms by which SRI practices spread, and how investors adopt and transform practices to suit their surrounding institutional contexts. Especially, the article draws attention to how different categories of (...) investors act as institutional entrepreneurs during specific historical periods, and how these roles come to shift as institutional rule systems of varying societal levels change. Thus, the insights gained are useful in the future research agenda concerned with advancing knowledge on idiosyncrasies and commonalities of national SRI manifestations, and to understand the reasons underlying such characteristics.

In Crull it is argued that, in order to confront outstanding problems in cosmology and quantum gravity, interpretational aspects of quantum theory can by bypassed because decoherence is able to resolve them. As a result, Crull concludes that our focus on conceptual and interpretational issues, while dealing with such matters in Okon and Sudarsky, is avoidable and even pernicious. Here we will defend our position by showing in detail why decoherence does not help in the resolution of foundational questions in (...) quantum mechanics, such as the measurement problem or the emergence of classicality.
