Climate change is a threat to food system stability, with small islands particularly vulnerable to extreme weather events. In Puerto Rico, a diminished agricultural sector and resulting food import dependence have been implicated in reduced diet quality, rural impoverishment, and periodic food insecurity during natural disasters. In contrast, smallholder farmers in Puerto Rico serve as cultural emblems of self-sufficient food production, providing fresh foods to local communities in an informal economy and leveraging traditional knowledge systems to manage varying ecological and (...) climatic constraints. The current mixed methods study sought to document this expertise and employed a questionnaire and narrative interviewing in a purposeful sample of 30 smallholder farmers after Hurricane María to identify experiences in post-disaster food access and agricultural recovery and reveal underlying socioecological knowledge that may contribute to a more climate resilient food system in Puerto Rico. Although the hurricane resulted in significant damages, farmers contributed to post-disaster food access by sharing a variety of surviving fruits, vegetables, and root crops among community members. Practices such as crop diversification, seed banking, and soil conservation were identified as climate resilient farm management strategies, and smallholder farmer networks were discussed as a promising solution to amass resources and bolster agricultural productivity. These recommendations were shared in a narrative highlighting socioecological identity, self-sufficiency, community and cultural heritage, and collaborative agency as integral to agricultural resilience. Efforts to promote climate resilience in Puerto Rico must leverage smallholder farmers’ socioecological expertise to reclaim a more equitable, sustainable, and community-owned food system. (shrink)

In the seminal works from Santos and Gozalo and Marletto and Vedral, it is shown how the Aharonov–Bohm effect can be described as the result of an exchange of virtual photons between the solenoid and the quantum charged particle along its propagation through the interferometer, where both the particle and the solenoid interact locally with the quantum electromagnetic field. This interaction results in a local and gauge-independent phase generation for the particle propagation in each path of the interferometer. Here we (...) improve the cited treatments by using the quantum electrodynamics formalism in the Lorentz gauge, with a manifestly gauge-independent Hamiltonian for the interaction and the presence of virtual longitudinal photons. Only with this more complete and gauge-independent treatment it is possible to justify the acquired phases for interferometers with arbitrary geometries. We also extend the results to the electric version of the Aharonov–Bohm effect. Finally, we propose an experiment that could test the locality of the Aharonov–Bohm phase generation. (shrink)

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

Despite the diagnostic relevance of thought insertion for disorders such as schizophrenia, the debates about its aetiology are far from resolved. This paper claims that in paying exclusive attention to the perceptual and cognitive impairments leading to delusional experiences in general, current deficit approaches overlook the role that affective disturbances might play in giving rise to cases of thought insertion. In the context of psychosis, affective impairments are often characterized as a consequence of the stress and anxiety caused by delusional (...) episodes. However, here I explore some of the conceptual and empirical reasons to think that affective problems might in fact play a crucial doxastic role in the aetiology of thought insertion. Finally, I conclude by proposing a way of integrating the main insights of my analysis with the current ‘two-factor’ deficit approach to thought insertion and I explore the potential adaptive role that some delusions might have within this framework.

La filosofía del siglo XX apenas puede entenderse sin lo que tiene de constatación de una grave crisis. Transformaciones históricas de largo alcance como la redefinición del Estado burocrático, la irrupción de la cultura de masas o el despliegue de la técnica industrial modificaron sustantivamente la experiencia que los hombres tenían de sí mismos y del mundo.La ambivalencia de esos cambios en lo que tienen, por un lado, de hitos de progreso racional, y, por otro, de verdaderas amenazas para el (...) bienestar de los hombres, obliga a que el pensamiento filosófico reconsidere lo que pueda quedar del hombre como sujeto de la razón moderna. La centralidad de la humanidad como sujeto de una historia pretendidamente racional, ¿ha quedado definitivamente atrás y apenas resta más que recordarla como una vana ilusión? ¿Es de todo punto inevitable que antes o después los logros de la humanidad se conviertan en procesos ciegos que podrían llegar a destruirla? Este libro trata de responder a estas preguntas, y a las que surgen de su hilo con- ductor, de la mano de la losofía del siglo XX. Autores de la talla de José Luis Pardo, Santiago Alba Rico, César Rendueles, Pablo López o Eduardo Maura, entre otros, agitan los términos de un debate que nos concierne a todos. (shrink)

After examining some of the most fundamental aspects of the general concept of ‘neuroright’ in the current discussion, this paper analyzes the concept of ‘the mental’ contained in the very first law of neurorights in the world currently under discussion in the Senate of the Republic of Chile (Bulletin 13.828-19 of the Chilean Senate). It is claimed that the lack of specificity of the target notion might not only posit difficulties for the creation of specific legal frameworks for the protection (...) of subjects from potential misuses of neurotechnologies with access to neural data, but it might also make very difficult the process of decision-taking when interpreting the law.

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”. El principal objetivo de este artículo es examinar las principales alternativas filosóficas contemporáneas a este problema: el doxasticismo—de acuerdo con el cuál los deli-rios deben ser caracterizados como creencias—y al anti-doxasticismo—el cuál niega el estatuto doxásticos de los delirios y ofrece una caracterización alternativa. (...) 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. Finalmente, expondremos algunas cuestiones conceptua-les y desafíos abiertos relacionados con el debate y que, a nuestro juicio, deberían de marcar la hoja de ruta de los filósofos de la mente interesados en los delirios en los próximos años.

En el campo de la psicología ecológica, la noción de affordance refiere a la percepción de oportunidades para la acción en los objetos del entorno. Problemáticamente, la falta de unidad conceptual parece dominar la caracterización del fenómeno haciendo que su significado varíe drásticamente dependiendo del autor que hace uso de ella. Este artículo ofrece una exégesis sistemática al trabajo original de J.J. Gibson enfocándose en la pregunta sobre qué son las affordances y cuáles son sus componentes fundamentales. Finalmente, se propone (...) una clasificación que permitirá categorizar diversas alternativas contemporáneas del concepto según la forma en la cual entienden la relación entre tales componentes.

An attribution of mental agency is defined as the act of assigning the initiation or authorship of a first personal phenomenal thought to a specific agent. This type of attribution is fundamental for the production of the belief that human beings are rational agents not only in behavioral terms, but also, in a cognitive manner. The top-down approach –one of the dominant theories in current literature– suggests that attributions of mental agency arise as retrospective rational explanations for the occurrence of (...) phenomenal thoughts. Thus, the agency of a thought would not be contained in its most fundamental phenomenal structure, rather, it would be an imposed category. After introducing the most fundamental elements of the debate, this paper evaluates the top-down model in order to identify its argumentative strengths and weaknesses. It is concluded that, although this model possesses a number of merits, it cannot deal in a plausible way with some fundamental conceptual challenges. (shrink)

ResumenEl enfoque posracionalista surge desde la crítica constructivista a la forma en que el cognitivismo tradicional conceptualiza la relación entre sujeto y realidad. Tomando como principal unidad de análisis el estudio de la identidad personal como fenómeno bio-psicológico, el modelo de Vittorio Guidano se ha convertido en la formulación más popular de este enfoque. Lamentablemente, la abrupta partida de su fundador parece haber dejado una serie de cuestiones conceptuales abiertas a la base del modelo. El presente artículo identifica los aspectos (...) fundamentales de la epistemología posracionalista de Guidano y luego de explorar su obra tardía, propone que es posible identificar dos momentos fundamentales en el enfoque: (i) Un primer momento (que denominamos Guidano 1 y que concentra la mayoría de la literatura en el tema) que es la expresión de una marcada influencia constructivista que implica la idea de que el principio organizador del funcionamiento de los sistemas humanos es la sobrevivencia. (ii) Un segundo momento (que llamamos Guidano 2 y que no ha sido exhaustivamente explorado en la literatura actual) que puede ser identificado como el producto de un giro hacia la filosofía fenomenológico-existencial. Acá, la identidad de un organismo no solo está orientada a la sobrevivencia, sino que, sobre todo, al sentido de la existencia misma. Se concluye clarificando el tipo de fenomenología que guiaría la práctica clínica de Guidano 2.Palabras clave: cognitivismo; constructivismo; fenomenología; posracionalismo. (shrink)

RESUMEN Una atribución de agencia mental es definida como el acto de asignar el inicio o autoría de un pensamiento en primera persona a un agente específico, esto, con el fin de generar grados suficientes de control sobre nuestra vida cognitiva. Si bien esta estrategia es fundamental para distinguir diferentes tipos de estados cognitivos - tales como deliberaciones, razonamientos, juicios, entre otros -, muchos autores han indicado que también es clave para entender experiencias cognitivas psicopatológicas en psicosis. Este artículo revisa (...) la forma en que la estructura subjetiva de los delirios de inserción de pensamiento puede ser utilizada como una estrategia para evaluar los méritos argumentativos de las teorías que intentan explicar la arquitectura y naturaleza de las atribuciones de agencia mental. Luego de evaluar algunos aspectos fundamentales de las dos teorías dominantes en la literatura actual, se sugiere que, a pesar de sus importantes aportes al desarrollo de la discusión, tales enfoques no poseen los recursos explicativos suficientes para lidiar con el desafío propuesto. ABSTRACT An attribution of mental agency is defined as the act of assigning the initiation or authorship of a first personal thought to a specific agent in order to generate sufficient degrees of control over our own cognitive life. Although this strategy is crucial to distinguish different types of cognitive states - such as deliberations, reasonings, judgements, among others -, a number of authors have suggested that it is also crucial to understand psychopathological cognitive experiences in psychosis. This paper explores the way in which the subjective structure of thought insertion can be used as a strategy to evaluate the merits of theories aiming at explaining the nature and architecture of attributions of mental agency. After examining some of the most fundamental aspects of the two dominant theories in current literature, I suggest that, despite the contributions made by such theories to the discussion, none of them is able to face the challenge in a plausible way.

The following paper presents and discuses the epistemological premises of one of the relativistic expressions of the so-called constructivism i.e. the social constructionism. Firstly, we trace constructivism’s theoretical origins and later, we distinguish the main ideas of Kenneth Gergen’s social constructionist proposal. The analysis is done in the following way: (a) we analyse the epistemological premises and the philosophical problems arising from them, and (b) we analyse the problematic impact these premises have in the praxis of social sciences. Finally, we (...) conclude that the exclusion of clear philosophical distinctions inside social constructionism undermines social constructionism’s plausibility. El siguiente artículo presenta y discute los postulados epistemológicos de una de las expresiones relativistas del denominado constructivismo i.e. el construccionismo social. En primer momento, se rastrean los orígenes teóricos del constructivismo y, posteriormente, se distinguen los principales postulados del construccionismo social de Kenneth Gergen. El análisis se realiza del siguiente modo: (a) Se analizan los supuestos epistemológicos y los problemas filosóficos derivados de éstos, y (b) Se analizan las consecuencias que los postulados construccionistas tienen en la praxis que llevan a cabo las ciencias sociales. Finalmente, se concluye que la exclusión de distinciones filosóficas claras por parte del construccionismo social le resta plausibilidad al enfoque. (shrink)

A considerable number of books and papers have analyzed normative concepts using new techniques developed by logicians; however, few have bridged the gap between the English legal culture and the Continental tradition in legal philosophy. This book addresses this issue by offering an introductory study on the many possibilities that logical analysis offers the study of legal systems. The volume is divided into two sections: the first covers the basic aspects of classical and deontic logic and its connections, advancing an (...) explanation of the most important topics of the discipline by comparing different systems of deontic logic and exploring some of the most important paradoxes in its domain. The second section deals with the role of logic in the analysis of legal systems by discussing in what sense deontic logic and the logic of norm-propositions are useful tools for a proper understanding of the systematic structure of law.

The objective of the article is to problematize the marginal place of the sex trade in the order of mining work, articulated from the psychodynamics of labor policies. We work with critical discourse analysis with individual and group interviews with male miners and with women self-defined as sex workers, from the Antofagasta Region. We conclude that the sex trade and the work of sex workers have a central place in the reproduction of the mining workforce, along with it, the search (...) for psychosexual well-being is satisfied, where sex work enhances the maintenance of the virile image, of a man who is not ready himself to the deconstruction of the hegemonic gender.
