We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...) to the problem of outcomes in quantum measurement by providing a sharp criterion for defining when an event has taken place. We analyze in detail in examples two situations in which in principle one could recover information about quantum coherence: a) “revivals” of coherence in the interaction of a system with the measurement apparatus and the environment and b) the measurement of global observables of the system plus apparatus plus environment. We show in the examples that the fundamental limitations due to gravity and quantum mechanics in measurement prevent both revivals from occurring and the measurement of global observables. It can therefore be argued that the emerging picture provides a complete resolution to the measurement problem in quantum mechanics. (shrink)

We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of coherence due to the use of realistic clocks to measure time to solve the measurement problem. The resulting formulation is framed entirely in terms of quantum objects without having to invoke the existence of measurable classical quantities like the time in ordinary quantum mechanics. The formulation eliminates any privileged role to the measurement process giving an objective (...) definition of when an event occurs in a system. (shrink)

Aristotelian virtue is the source of the soul’s best actions and passions. It can compel us to do the best acts and doings, always in a better way. Aristotelian virtue helps us to act under the right reasoning, which is elected from an intellectual disposition called prudence, which is in charge of uniting knowledge and action. Aristotle says one can learn to be virtuous through exercising good habits, with formation, experience and time to do such an exercise. Besides, actions according (...) to virtue will be nice by themselves, if a virtuous man judges righteously. This is precisely the root of good living and good acting for Aristotle. The activities performed by a good man are, then and by themselves, good, nice and happy, and are also related to virtue and to the actions of a virtuous man. This paper aims at analyzing virtue as a pathway to happiness, the actions to achieve it and to describe some intellectual and moral virtues established within the moral philosophy of this thinker.

Among various issues that concern human beings, there are a few that are of current interest and have really grabbed our attention: love for nature, environmental defense, and worries about Biodiversity and Biosecurity. The article considers one particular aspect regarding the bioethical concern of using animals in experiments that might benefit both humans and animals. The problematic aspect of the bioethical use of animals in scientific experimentation has been and will remain crucial for human life. Additionally, the results of this (...) type of research could contribute to animal welfare, which have an impact on public health. (shrink)

Animals have made possible to science the production of new knowledge within the fields of Biology and Physiology. This knowledge has allowed the development of methods of diagnosis and treatments that improve the quality of life of human beings and animals. Therefore, the use of animals for testing should be made with respect, and considering the possible reactions of the animals and their own ethology. Animal testing might remain under debate in the coming years due to the necessity to adapt (...) the care of the animals used for testing to the opportunities and challenges that might come in the future. Thus, it will be relevant for researchers to remain up to date with the progress of procedures. Bearing all this in mind, it is necessary to examine the ethical appropriateness of the legal aspects considered by Colombian regulations concerning scientific experimentation and testing. Such aspects are discussed in the article and a proposal for a National Legislation that takes into account all the technical, scientific and bioethical elements that are involved in animal testing is outlined.

Determined to fight alone, stripped from the security that could be offered by community, human beings of our times have openly embraced their individuality. With such a purpose, consciously or unconsciously, they have decided to decimate the institutions and to break with the burden imposed by rules, laws and agreements, which they consider are oppressive and limit their personal development. Thus, the article offers a philosophical review of the concept of community and examines the necessity of its reconfiguration as social (...) linking force. This arises as an answer to possible risks associated with the coming of a new individual that adopts her selfhood as the only truth, which leads to not acknowledging otherness and plurality, and to individualism as the only possible way of being.

Laura Montoya Upegui identifica la compasión como un sentimiento que mueve a la acción. Es una lección útil dirigida a la transformación social. En medio de las dificultades, optó por la reflexión y la evaluación de los eventos inesperados en la condición humana para dirigir la mirada hacia la vida buena. Cuando es calumniada, identifica y acepta las emociones sociales e individuales, alejándose del miedo. Ella comprende que en el desarrollo humano, lo material y lo espiritual no se excluyen. En (...) la actualidad, existe una fuerte tensión política en Colombia que reclama de la sensibilidad social y los propósitos comunes. Como lo plantea Nussbaum, y según las vivencias de Santa Laura Montoya, la compasión, la esperanza práctica y la visión imaginativa pueden guiar el camino hacia el desarrollo humano. (shrink)

IntroductionTranscranial magnetic stimulation is a consolidated procedure for the treatment of depression, with several meta-analyses demonstrating its efficacy. Theta-burst stimulation is a modification of TMS with similar efficacy and shorter session duration. The geriatric population has many comorbidities and a high prevalence of depression, but few clinical trials are conducted specifically for this age group. TBS could be an option in this population, offering the advantages of few side effects and no pharmacological interactions. Therefore, our aim is to investigate the (...) efficacy of TBS in geriatric depression.Clinical trial registration[https://clinicaltrials.gov/ct2/], identifier [NCT04842929]. (shrink)

Research in psychology suggests that some individuals are more sensitive to positive than to negative information while others are more sensitive to negative rather than positive information. I take these cognitive positive–negative asymmetries in information processing to a Bayesian decision-theory model and explore its consequences in terms of decisions and payoffs. I show that in monotone decision problems economic agents with more positive-responsive information structures are always better off, ex ante, when they face problems where payoffs are relatively more sensitive (...) to the action chosen when the state of nature is favorable.

The present introduction contains a short scientific biography describing the many different areas of logic and computation where Luis contributed significant advances. (shrink)

La ética de Abelardo puede ser vista como el intento de confeccionar una doctrina de la conciencia moral. Tal intento fue en realidad un proyecto inconcluso en el que Abelardo pretendía demostrar a través de la dialéctica en qué consistía la auténtica moral cristiana sobre la base de su contraste con la tradición filosófica. Este artículo desarrolla las implicancias de ese proyecto desde tres perspectivas (1) situando la postura de Abelardo en el marco de la reflexión ética del siglo XII, (...)

We describe a sequent calculus, based on work of Herbelin, of which the cut-free derivations are in 1-1 correspondence with the normal natural deduction proofs of intuitionistic logic. We present a simple proof of Herbelin's strong cut-elimination theorem for the calculus, using the recursive path ordering theorem of Dershowitz.

The development of a kind of authority concentrated in one person is surely one of the main social processes in the first two centuries CE Christianity and also one of those which left the most perennial and influent legacies in the Christian Church of posterior centuries. In this sense, Ignatius of Antioch is not only an historical witness of the dynamics around such a process in Proconsular Asia of his time. He is also, and most of all, an historical agent (...) who, using his rhetorical abilities and imprisonment conditions, works for the reorganization of the Christian communities around the one he defended to be the representation in the holy supper of God the Father himself.

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers'' perceptions of ethical consumer behaviour using Muncy and Vitell''s (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might (...) question the ability of organisations to consider the EU as one homogeneous market. (shrink)

Marsilio de Pádua e Guilherme de Ockham viveram seus últimos anos na corte de Luís da Baviera. Ambos opuseram-se aos papas da época. Entretanto, a posição deles a respeito do primado do sumo pontífice não é idêntica. Enquanto Marsílio a nega quase totalmente, Ockham observa que se trata de um problema de cunho teológico e critica os argumentos de Marsílio.

Epistemic value is a kind of value possessed by knowledge, and perhaps other epistemic goods such as justification and understanding. The problem of explaining the value of knowledge is perennial in philosophy, going back at least as far as Plato’s Meno. One formulation of the problem is to explain why and in what sense knowledge is valuable. Another version of the problem is to explain why and in what sense knowledge is more valuable than mere true belief or opinion. This (...) article looks at various formulations of the value problem and various accounts of the value of knowledge in ancient and modern philosophy. The article then considers some contemporary discussions of the value problem, including the charge that reliabilist accounts cannot account for the value of knowledge over mere true belief. Various virtue-theoretic accounts of epistemic value are discussed as possible improvements over process reliabilism, and the epistemic value of understanding (as compared to knowledge) is considered.

RESUMEN Una vez que el foco de la reflexión pasa de las teorías ideales a la aplicación de la justicia social, centrada en las instituciones de las sociedades democráticas, se requiere prestar especial atención a los estilos de vida. Estos tienen una alta incidencia en cómo la justicia es realizada y afectan tanto a la desigualdad económica como a la disponibilidad de los recursos naturales. En nuestras sociedades es posible establecer restricciones a los estilos de vida, especialmente en aquellos casos (...) en que, por el efecto de algunas dinámicas sociales, aquellos se desacoplan de las concepciones del bien. Se defiende que, en tales casos, la base normativa que permite exigir el respeto a los estilos de vida se disuelve y por ello es posible justificar su restricción. ABSTRACT Now that the focus of reflection has shifted from ideal theories to the application of social justice, centered on the institutions of democratic societies, it is necessary to pay special attention to lifestyles, since they not only influence the realization of justice, but also have an effect on economic inequality and the availability of natural resources. In our societies, it is possible to place restrictions on lifestyles, especially in those cases in which, influenced by certain social dynamics, they disengage from conceptions of the good. The article argues that, in those cases, the normative base grounding the demand that lifestyles be respected is dissolved, thus justifying their restriction. (shrink)

Isaac de Pinto was an active financier, economist and homme de lettres. Descending from a Jewish family of Portuguese origin, he lived in Amsterdam, Paris and London. Throughout his life, he enjoyed close relationships and made regular contact with important figures of the European Enlightenment. The main purpose of this article is to show that the concern with the Jewish problems, namely those relating to the difficult economic situation of the Portuguese nation in Amsterdam in the second half of the (...) eighteenth century, is a key factor in explaining the ongoing moral and apologetic dialogues that Isaac de Pinto maintained separately with Voltaire and Diderot. ☆ The authors are most grateful for the comments and suggestions provided by Antoin Murphy and two referees of this journal.

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.

To identify how digital media are being used by community-led initiatives of the Centro Region of Portugal, and to identify the requirements that a digital platform for mediation between agents in the territory should have, two focus groups were conducted, involving six small-sized community-led initiatives and six larger-sized community-led initiatives. This article details the results of these focus groups, according to the following main categories: use of existing communication and mediation tools; the purpose of use of digital tools; type of (...) experiences prompted by digital tools and attributes and features desired in a digital platform to support community-led initiatives. The results show differences between the use and needs of digital tools by small- and larger-sized initiatives and offer interesting insights to prototype an innovative digital solution, to enhance the actions of community-led initiatives. A reference framework for digital mediation strategies and a mobile app prototype were developed, based on these surveys. The article contributes with an analytical view about the development of digital solutions, which aim to strengthen the relationship among agents of local communities and promote mediation mechanisms among all stakeholders in territorial-based innovation.
