Our interdisciplinary studies for over twenty years applied to the comparative history of the Romané Chavé (European Gypsies) with the high military castes of India (Rajputs and Kshatrivas), had come off, as from 1964, to the following conclusions: the more a language is similar on the lexical level to Hindi-Rajasthani and, on the morphological one to Jodhpuri, the more it is similar to Gypsy language—Romani, the more a culture is similar to the culture of the Rajputs and Kshatrivas, the more (...) it is similar to Romani culture; the more someone is similar to the members of the military castes of India and generally to the people of Hindu religion of North Western India, of the Delhi State and its surroundings (Haryana, Western Uttarprades, Rajasthan and Sindh), the more he is similar to a Romano Chavo.

“Para que isso servirá em minha vida?” Ao longo de minha trajetória como professor do ensino secundário, ouvi esta pergunta algumas vezes. É provável que nós professores de filosofia não sejamos um alvo privilegiado dessa pergunta provocadora. Trata-se mesmo de uma questão legítima, ainda mais para nós: latinoamericanos, brasileiros, nordestinos, piauienses. Trata-se de uma pergunta que evoca um certo desespero, uma certa pressa, um tipo de agonia que é bem nossa; como quando dizemos “estou agoniado”. Queremos tudo “pra já”. Parece (...) que jamais nos daremos o direito de viver e aprender algo pelo simples fato de que o saber é bom e merece ser fruído. (shrink)

This work has two objectives. The first is to begin a mathematical formalism appropriate to treating particles which only interact with each otherindirectly due to hypothesized memory effects in a stochastic medium. More specifically we treat a situation in which a sequence of particles consecutively passes through a region (e.g., a measuring apparatus) in such a way that one particle leaves the region before the next one enters. We want to study a situation in which a particle may interact with (...) other particles that previously passed through the system via disturbances made in the region by these previous particles.Second, we apply the type of stochastic process appearing in this context to the stochastic interpretation of quantum mechanics to obtain a modified version of this interpretation. This version is free of many of the criticisms made against the stochastic interpretation of quantum mechanics. (shrink)

Most people assume that criminal offenders have only been convicted of a single crime. However, in reality almost half of offenders stand to be sentenced for more than one crime. The high proportion of multiple crime offenders poses a number of practical and theoretical challenges for the criminal justice system. For instance, how should courts punish multiple offenders relative to individuals who have been sentenced for a single crime? How should they be punished relative to each other? Sentencing Multiple Crimes (...) discusses these questions from the perspective of several legal theories. This volume considers questions such as the proportionality of the crimes committed, the temporal span between the crimes, and the relationship between theories about the punitive treatment of recidivists and multiple offenders. Contributors from around the world and in the fields of legal theory, philosophy, and psychology offer their perspectives to the volume. A comprehensive examination of the dynamics involved with sentencing multiple offenders has the potential to be a powerful tool for legal scholars and professionals, particularly given the practical importance of the topic and the relative dearth of research about punishment of multiple offense cases.

The theory of chemical symbiosis suggests that biological systems started with the collaboration of two polymeric molecules existing in early Earth: nucleic acids and peptides. Chemical symbiosis emerged when RNA-like nucleic acid polymers happened to fold into 3D structures capable to bind amino acids together, forming a proto peptidyl-transferase center. This folding catalyzed the formation of quasi-random small peptides, some of them capable to bind this ribozyme structure back and starting to form an initial layer that would produce the larger (...) subunit of the ribosome by accretion. TCS suggests that there is no chicken-and-egg problem into the emergence of biological systems as RNAs and peptides were of equal importance to the origin of life. Life has initially emerged when these two macromolecules started to interact in molecular symbiosis. Further, we suggest that life evolved into progenotes and cells due to the emergence of new layers of symbiosis. Mutualism is the strongest force in biology, capable to create novelties by emergent principles; on which the whole is bigger than the sum of the parts. TCS aims to apply the Margulian view of biology into the origins of life field. (shrink)

Este trabalho se propõe a apresentar o tema da compaixão em Schopenhauer e o da solidariedade em Rorty a partir da perspectiva filosófica de cada um dos pensadores. Não pretendemos aprofundar o problema em quaisquer das perspectivas, seja a metafísica ou a neopragmatista, mas apenas mostrar como a perspectiva de cada filósofo leva a uma concepção, ao menos aparentemente, diferente sobre um problema comum.

Many students feel despair when addressing systemic issues of ethical significance, such as climate change, and student despair has been exacerbated by the circumstances of the Covid-19 pandemic. This creates an unwelcoming space for authentic student engagement. To address the problem, we present an imaginary of radical hope, a pedagogical tool informed by trauma, for developing a brave space for class discussion. It is psychologically beneficial to acknowledge negative emotions, clearing the emotional space for students to engage. Therefore, we frame (...) ethics courses with an uncomfortable discussion, asking students to draw from their positionality and share their feelings of hope and despair, related to course material. In this paper, we explain the problem of despair motivating the project, describe the pedagogical and ethical support of our strategy, share the assignment, activity, and examples, and discuss takeaways.

Afshar et al. claim that their experiment shows a violation of the complementarity inequality. In this work, we study their claim using a modified Mach-Zehnder setup that represents a simpler version of the Afshar experiment. We find that our results are consistent with Afshar et al. experimental findings. However, we show that within standard quantum mechanics the results of the Afshar experiment do not lead to a violation of the complementarity inequality. We show that their claim originates from a particular (...) technique they use to analyze their results. In their analysis, they assume a classical concept, that particles have a definite trajectory before detection, thus, they obtain which-way information by particle detection plus path extrapolation by applying momentum conservation. This analysis technique is standard in experimental particle physics. Important discoveries such as the detection of vector bosons have been made through the application of this technique. We note that particle detection plus path extrapolation is a suitable technique within de Broglie-Bohm theory of quantum mechanics. (shrink)

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4 -- our formulation has several important metatheoretic properties. In addition, we study models of IS4 -- not in the framework of Kripke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models (...) but also a means of modelling proofs as well as provability. (shrink)

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

The extent to which game play is experienced as engaging is an important criterion for the playability of video games. This study investigates how video games can be designed towards increased levels of experienced engagement over time. For this purpose, two experiments were conducted in which a total of 35 participants repeatedly played a video game. Results indicate that experienced engagement is based on the extent to which the game provides rich experiences as well as by the extent to which (...) the game provides a sense of control. In view of the influence of both game features and players’ expertise on the levels of experienced richness and control, it is concluded that game features should be modified over time to maintain optimal levels of engagement.

The paper addresses the philosophical presuppositions underlying the concept of the “international system.” It suggests that the international system is not a system in any technical sense of this term, but rather a static order – an international order – founded on international boundaries. Nor is there any place in reality that corresponds to the term “international” or, more broadly, the “international plane.” The international plane is a state analogous to the quantum state in physics – a quantum state writ (...) large. In reality, the international plane is reducible to an international event taking place on an international boundary. The international order of boundaries, in turn, is ultimately rooted in common sense and metaphysics – the two founding positions of modern philosophy. (shrink)
