En su libro The Tapestry of Reason: An Inquiry into the Nature of Coherence and its Role in Legal Argument,1 Amalia Amaya argumenta las ventajas de adoptar una postura coherentista en el derecho. Concretamente, su tesis principal es la siguiente...

I will center the discussion of the Hart-Fuller debate on the five claims Hart mentions might be understood as legal positivisms main tenets: (1) the command theory; (2) the no necessary connection thesis; (3) the methodological claim; (4) the charge of positivism as formalism and the problem of interpretation; and (5) the meta-ethical confusion. In light of these five claims, I will explore whether the exchange of views between Hart and Fuller in 1957 truly amounted to a debate. Sorting out (...) this issue is the aim of this article.

In this work, we present a new approach to solve the location management problem by using the reporting cells strategy. Location management is a very important and complex problem in mobile computing which aims to minimize the costs involved. In the reporting cells location management scheme, some cells in the network are designated as reporting cells . The choice of these cells is not trivial because they affect directly to the cost of the mobile network. This article is focused on (...) the use of high performance computing to execute a parallel heuristic that places optimally the RCs in a mobile network, minimizing its total cost. The main goal of this work is to demonstrate that the collaborative work of different evolutionary algorithms can obtain very good results. For this reason, we have implemented a parallel heuristic and six evolutionary algorithms that works in a parallel way on a cluster to solve the RCs problem. (shrink)

Is there a theoretically interesting notion that is a natural extension of the concept of rigidity to general terms? Such a notion ought to satisfy two Kripkean conditions. First, it must apply to typical general terms for natural kinds, stuffs, and phenomena, and fail to apply to most other general terms. Second, true 'identification sentences' (such as 'Cats are animals') containing general terms that the notion applies to must be necessary. I explore a natural extension of the notion of rigidity (...) to general terms, the notion of an essentialist predicate. I argue that, under natural assumptions, this notion satisfies the two Kripkean conditions. (shrink)

Apoyándose en el análisis crítico de discusiones clásicas y contemporáneas sobre democracia laboral, el artículo examina, en primer lugar, los argumentos que pueden formularse para sostener que la democratización del trabajo es posible y deseable, o, por el contrario, que es imposible o ilegítima. Se distinguen a continuación dos escenarios de democratización del trabajo: el primero piensa la democratización del trabajo como una democratización del gobierno corporativo; el segundo la concibe como una democratización de la participación en la actividad colectiva (...) del trabajo. El artículo defiende que la radicalización de la democracia exige democratizar los entornos laborales y comprender el trabajo como un espacio de formación de hábitos democráticos como la autonomía, la cooperación y la deliberación colectiva.

Con base en el realismo interno de Putnam que admite una postura realista compatible con la relatividad conceptual, en este artículo expongo la necesidad de una noción de verdad epistémica y social. Esta noción de verdad nos permite inferir con suficiente seguridad que las razones con las que contamos son las mejores razones para asegurar que nuestras creencias, decisiones y políticas están restringidas por los límites que la Realidad impone y por tanto, hay altas probabilidades de que nuestras acciones sean (...) exitosas.

Tarski implicitly postulated that a certain pre-theoretical concept of logical consequence and his technical concept of logical consequence are co-extensional. This chapter makes explicit a few theses about logical consequence or logical truth that sound Tarskian somehow, including one that most deserves the name ‘Tarski's Thesis’. Some of these theses are probably true or close to true but weaker than Tarski's. Some are false but stronger than Tarski's. Tarski's Thesis plausibly postulated that a sentence of a classical language possibly extended (...) with non-traditional extensional logical constants is logically true, if it is true in all classical interpretations of all its non-logical constants. But it is noted that this thesis turns out to be false on most conceptions of logical truth, for some sentences of a classical language extended with extensional logical constants are true in all classical interpretations of all its non-logical constants, but are not necessary.

This chapter explores the impact of Ralph Waldo Emerson on Latin American philosopher José Ingenieros. The chapter maintains that this impact is crucial because it aids in understanding and appreciating Ingenieros and his moral philosophy and it has never before been explored. However, for over a hundred years, this unique connection has been hiding a link between Latin American philosophy and American pragmatism.

El presente artículo es un ejercicio hermenéutico que pone en diálogo la filosofía y la teología a partir de la categoría de espiritualidad. Para tal fin asume el rol del poeta, figura crucial en la filosofía del último Heidegger, y lo identifica con el sacerdote, figura importante en la teología. Procediendo de este modo se concluye luego cómo el poeta y el sacerdote son los profetas de lo sagrado que contribuyen a una humanización de la tierra, superando cualquier intento cosificador (...) por parte de la técnica.

Music performance anxiety (MPA) is a multifaceted phenomenon occurring on a continuum of severity. In this survey study, we investigated to what extent the affective (anxiety), cognitive (catastrophizing), and somatic (bodily complaints) components of MPA prior to solo performances vary as a function of age, gender, instrument group, musical experience, and practice as well as how these MPA components relate to self-rated change in performance quality from practice to public performance. The sample comprised 75 male and 111 female classical music (...) university students, aged 15–45 years. Age was positively associated with anxious feelings and bodily complaints. Compared to male students, female students reported significantly more anxious feelings and catastrophizing. Singers reported less anxious feelings and catastrophizing than instrumentalists. Breathing-, mouth- and throat-related complaints were highest among singers and wind players; hand- and arm-related complaints were highest among string players and pianists. The indices of musical experience and practice had marginal effects. An average of four bodily complaints bothered the participants strongly to very strongly. Worsening in performance quality from practice to public performance was reported by almost half of the participants and was best predicted by anxious feelings and breathing-related complaints. We conclude that age, gender and instrument play a significant role in understanding the phenomenology of MPA. Musicians should be examined according to these characteristics rather than as one homogenous population. In particular, it might be valuable to develop assessment tools for MPA that incorporate items related to the bodily complaints that are most relevant to the different instrument groups. Breathing-related complaints could add an important dimension to the investigation of MPA and music performance. Finally, the high percentage of students reporting worsening of their performance quality from practice to public performance highlights the need of professional support to help music students be able to perform at their best and thrive as artists.

The use of some nonhuman primates in invasive research—unlike that on animals more generally—has been severely restricted or banned in much of the world. This trend toward severe restrictions or bans raises the question: Has the time come to end invasive research with all primates? In this chapter, we offer an overview of the main ethical questions surrounding the use of primates in invasive research, evaluate some of the leading arguments in favor of and against such research, and propose some (...) ethical recommendations for conducting this research. As we argue, the case for phasing out the use of primates in invasive research is not as straightforward as some might think. Stringent restrictions must be adopted if scientifically and ethically justifiable invasive research with primates is to continue. (shrink)

Objective: This study aimed to compare the effects of two intervention programs, high-intensity interval training and moderate-intensity training, on anxiety, depression, stress, and resilience during the confinement caused by the coronavirus disease 2019 in healthy adults.Methods: A total of 67 adults who participated were randomly assigned to two groups: HIIT and MIT groups. The MIT group had to perform a home-based intervention based on aerobic exercises, whereas the HIIT group had to perform a home-based intervention based on HIIT exercises. The (...) two groups had to complete the same physical exercise volume, 40 min per session during the confinement period. Depression, anxiety, stress, and resilience were assessed before and after the intervention.Results: Results showed that HIIT and MIT significantly reduced the stress, anxiety, and depression as well as increase the resilience. Moreover, the improvements obtained in the HIIT group seem to be greater than those of the MIT group in depression.Conclusions: HIIT and MIT decreased anxiety, stress, and depression as well as increased resilience during the COVID-19 confinement. In addition, the HIIT intervention seemed to be more beneficial to reduce depression than the MIT intervention. (shrink)

En este escrito, 1) hago una presentación del tipo de análisis conceptual quehace Wittgenstein en algunas obras posteriores al Tractaus; me refiero,específicamente, a una cierta manera de proceder que consiste en ladescripción de los diferentes usos de un concepto, y que tiene como finarrojar luz sobre las condiciones de funcionamiento de nuestro lenguaje para,así, llegar a la solución de un determinado problema filosófico. 2) Examinoalgunos pasajes de las Investigaciones en los que que Wittgenstein analizaconceptos psicológicos y señalo lo que considero (...) son algunas fallas de lasinterpretaciones naturalistas, externalistas y mentalistas de esos pasajes. 3)Presento una interpretación de la perspectiva de Wittgenstein en torno alproblema de la existencia y naturaleza de los estados y procesos psicológicos,que tiene en cuenta, tanto el tipo de análisis que Wittgenstein hace, comoalgunas afirmaciones suyas extraídas de las Investigaciones y de LosCuadernos Azul y Marrón.

The article proposes a theory on which quotations are unstructured, context-insensitive devices that get their referents fixed by a conventional wholesale reference-fixing rule. First, it criticizes recent theories for postulating eccentric or anomalous facts concerning the contribution of noun phrases to truth conditions, the semantics of demonstratives or general syntax. Second, it notes that the proposed theory is not subject to some familiar objections to classical theories, nor to eccentricity or anomalousness complaints. Third, it shows that recent arguments that quotations (...) must be structured or equivalent with demonstrative phrases, or that they cannot get semantic referents via linguistic conventions, are mistaken. It is noted that semantic unstructuredness, non-demonstrativeness, and conventional wholesale reference-fixing exploiting pre-referential term-referent relations are combined in some naturally occurring classes of terms.

Paulo Freire consistently upheld humanization and mutuality as educational ideals. This article argues that conceptualizations of knowledge and how knowledge is sought and produced play a role in fostering humanization and mutuality in educational contexts. Drawing on Mary Shelley’s novel Frankenstein, this article focuses on the two central characters who ‘ardently’ pursue knowledge at all costs. It will be argued that the text suggests two possible outcomes from the pursuit of knowledge. One is mutuality; the other is social disconnectedness.

We advance the thesis that the method of experimental economics can make significant contributions to normative, as opposed to descriptive, business ethics. We contend that there are two basic ways in which experimental economics may make this contribution, and we exemplify these ways by pointing to experimental support of social contract theory as rational foundation for business ethics. These two ways are: (1) adding psychological realism; and (2) testing some quasi-empirical assumptions present in normative theory. In order to make good (...) our methodological claim, we first describe the methodological rules of experimental economics, distinguishing this method from other behavioral business ethics approaches. We also contemplate the possible objection that empirical methods cannot bear on normative ethics because there is no way of bridging the gap between descriptive theory (how people behave) and normative theory (how people ought to behave).

"Ay, no quieres, te asusta la pobreza: no quieres ir con zapatos rotos al mercado y volver con el viejo vestido" dice Pablo Neruda en uno de los poemas de su libro "Los versos del capitán".

El impacto de los movimientos emancipatorios en las sociedades contemporáneas es incuestionable; alcanza incluso al ámbito académico, donde se busca comprender las experiencias que los motivan y se llega a tomar partido por sus causas. Sin embargo, estos movimientos están orientados a la consecución de derechos para identidades concretas, como las personas no binarias, de forma que se consiga paliar o incluso eliminar la situación de desigualdad que las oprime. Así, podría parecer que las causas de los grupos oprimidos resultan (...) «ajenas» para los grupos dominantes, los cuales no tienen que luchar por sus derechos, pues ya disfrutan de ellos, lo que confinaría el discurso acerca de las reivindicaciones y las experiencias que las motivan exclusivamente a los colectivos oprimidos. Abordaremos la polémica cuestión de hablar de una causa ajena desde la epistemología feminista del punto de vista y las literaturas sobre opresión e injusticia epistémica. A grandes rasgos, siguiendo la línea iniciada por Gayatri Chakravorty Spivak (1988), quien se distancia de autores como Michel Foucault o Gilles Deleuze, a quienes acusa de rechazar el hablar por otros asumiendo falsamente que las personas oprimidas pueden representar de manera transparente sus propios intereses, entenderemos el hablar de una causa ajena como un hablar con. Frente a la oposición escuchar versus hablar por, apostaremos por un informado hablar con que no participe de la esencialización de los oprimidos como sujetos no ideológicamente construidos. (shrink)
