El gran zoo (1984), del poeta cubano Nicolás Guillén, ofrece distintas representaciones sobre el Caribe. El artículo argumenta que el texto de Nicolás Guillén se inscribe dentro del movimiento literario hispanoamericano de la neovanguardia. Luego, se examinan algunas características formales del texto, tomando como ejemplo los poemas “El sueño” y “Guitarra”. Otro poema que se estudia con más detenimiento es “El tenor”, el cual parodia la división entre la alta cultura y la cultura popular. Por último, se analizan varias alusiones (...) del poemario al contexto histórico de la Guerra Fría y la Carrera Espacial. (shrink)

Sin embargo, el punto de encuentro está dado en la perspectiva y en las condiciones que determinan la posibilidad de proponer un pensamiento crítico y propositivo desde América Latina. (shrink)

Knowledge brokers are among the main channels of communication between scientists and the public and a key element to establishing a relation of trust between the two. But translating knowledge from the scientific community to a wider audience presents several difficulties, which can be accentuated in times of crisis. In this paper we study some of the problems that knowledge brokers face when communicating in times of crisis. During the first wave of the COVID-19 pandemic, we collected interviews with Italian (...) experts that played a major role as knowledge brokers in the local media. We asked them questions about five main topics: the features and role of science communicators; the use of language in communicating science; the importance of the relation of trust with the public; the peculiarity of communicating in a context of emergency; the problem of disagreement among experts, and its public perception and communication. The goal of this paper is to understand, through the words of knowledge brokers themselves, what they consider as best practices (and obstacles) to create trust between scientists and the public. Our empirical work can inform normative accounts of what knowledge brokering should be about. (shrink)

In this paper we address the problem of short-term electric energy prediction using a time series forecasting approach applied to data generated by a Paraguayan electricity distribution provider. The dataset used in this work contains data collected over a three-year period. This is the first time that these data have been used; therefore, a preprocessing phase of the data was also performed. In particular, we propose a comparative study of various machine learning and statistical strategies with the objective of predicting (...) the electric energy consumption for a given prediction horizon, in our case seven days, using historical data. In this paper we have tested the effectiveness of the techniques with different historical window sizes. Specifically, we considered two ensemble strategies, a neural network, a deep learning technique and linear regression. Moreover, in this study, we tested whether the inclusion of meteorological data can help achieve better predictions. In particular, we considered data regarding temperature, humidity, wind speed and atmospheric pressure registered during the three-year period of data collection. The results show that, in general, the deep learning approach obtains the best results and that such results are obtained when meteorological data are also considered. Moreover, when meteorological data is used, a smaller historical window size is required to obtain precise predictions. (shrink)

The extent to which people anticipate and are influenced by the potential future consequences of their current behavior is called Consideration of Future Consequences. A well-established tool to measure this construct is the 14-item Consideration of Future Consequences Scale. The CFC-14 has shown appropriate psychometric properties in several languages. This scale comprises two factors: the CFC-Immediate and the CFC-Future. The main goal of this study was to assess the psychometric properties and internal consistency of the CFC-14 Scale in Spanish, using (...) an Argentine sample. A secondary goal was to determine its convergent validity with impulsivity, and determine differences across gender and age groups. Using a web-based survey, we collected data from 512 participants aged 13-74 years. Confirmatory Factor Analysis showed a 2-factor model as the best solution for 13-items version. Standardized regression weights ranged from.50 to.66 for CFC-F and between.43 and.83 for CFC-I. Composite reliability was also adequate: CFC-F achieve? =.80 and CFC-I? =.82. There were no differences across gender and age. The CFC-F subscale and UPPS-P subscales correlations, were negative and significant, highlighting the negative and moderate correlation between CFC-F and the lack of premeditation, a dimension strictly related to intertemporal decisions making. Thus, CFC-14 has adequate psychometric properties in an Argentinian population, although more studies are necessary to determine the robustness of these findings. (shrink)

En el socialismo de la transición, De los Ríos fue una figura a recuperar. Su sentido humanista del socialismo permitió al PSOE fundar en su propia historia republicana el nuevo compromiso del socialismo con la libertad. En el socialismo de los derechos civiles también tiene un lugar. De los Ríos apadrinó a Federico García Lorca, desde Granada a Nueva York y con La Barraca. El amor y el exilio acabó uniendo sus familias. También nombra a la primera mujer alto (...) cargo gubernamental: Victoria Kent, directora de prisiones.Se conoce menos otra dimensión de su trayectoria política de la que se ocupa este libro: su laicismo religioso. Dos rasgos que en la España de duelos a garrotazos parecen antagónicos. Sin embargo, ambos son característicos de su personalidad política e intelectual. Fue el ministro que lideró la política laicizadora de la II República, desde Justicia, primero, e Instrucción pública, después, llevando "siempre la batuta"?como informaba Tedeschini, el nuncio de la época -. Por otra parte, desde un cristianismo heterodoxo, no dejó de estimar la emoción religiosa, como lugar donde "fecundan los más hondos deseos del ideal". Se autodefinió "cristiano erasmista". Así le caracterizan Indalecio Prieto, en el obituario tras su muerte en el exilio, y el propio García Lorca, su poeta. (shrink)

Objective of the study: To analyze the costs and profits of sugarcane production regarding the cultural practices of sugarcane suppliers. Methodology/approach: This study positions itself in this gap by comparatively analyzing 6 types of cultural practices: unraveling, windrowing, application of correctives, herbicides, insecticides and fertilizers, with the option of two systems Fixed rate (TF) and Variable rate (TV). Originality/Relevance: Brazil is a world reference in sugarcane production, with the State of São Paulo being the largest Brazilian producer. However, for sugarcane (...) suppliers to maintain this activity there is a need to reduce production costs and increase profitability/ha. However, there is a theoretical-practical gap in the financial assessment (costs and profits) of different cultural practices inherent to sugarcane production. Main results: The results demonstrated that the costs of cultural practices represent more than 30% of the total sugarcane production costs. The TF system proved to be more cost-efficient in the following operations: correctives, herbicides and insecticides. In the application of fertilizers, the TV system, in broadcast mode, had the best result. Finally, the profit/ton was R$1.70, demonstrating a very low profit margin/ha given the risk of the activity. Theoretical/methodological contributions: The sample for this research comprised 55 sugarcane suppliers from the State of São Paulo, whose data were obtained through a survey. The comparative analysis was based on the difference in costs of cultural practices and the estimation of the level of certainty (profit/costs), analyzed through the cumulative frequency carried out through the Monte Carlo Simulation (SMC).

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in the (...) central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

The costs of agricultural inputs added to those of labor represent almost a third of the total cost of Brazilian sugarcane production. This study analyzes the behavior of the price per ton of sugarcane in Brazil, relating it to the main production costs of this cultivation. Twelve price indicators from January 2015 to December 2020 were evaluated. First, the data were adjusted to a multiple linear regression model to identify the significant variables on variation in the price per ton of (...) sugarcane. Then, the Monte Carlo simulation was used to measure the level of certainty of occurrence of these variables, and forecasts were obtained from the adjustment of ARIMA models. The results showed the influence of the costs of diesel oil, two agricultural pesticides, and daily laborers on the price of sugarcane, besides an increasing trend of its, providing relevant short-term projections for decision-making about investments in the agribusiness sector.

The law of the Milanese Church in early modern times was both postulated and experimental. Just after Trent, Carlo Borromeo exercised the “immemorial” rights of the archbishopric without demonstrating them. His successors interpreted his show of strength as custom, highlighting the fame of archbishop’s acts, therefore the consensus populi, at a time when this argument faded into canonical doctrine. But the common experience was only valid to confirm saint Carlo’s intuition and deeds. In 1620, such reasoning justified the bearing of (...) arms by the Archbishop’s minions, with description and evidence: was it narratively and legally effective? (shrink)

Este artigo discute o conceito de herdabilidade, empregado pela genética do comportamento, genética molecular e a teoria da herdabilidade, sob a perspectiva do modelo reticulado de racionalidade científica, de Larry Laudan. Analisa os argumentos contrários à utilização do termo herdabilidade focando principalmente nos resultados de experimentos da genética do comportamento. Conclui que algumas críticas ao termo herdabilidade são válidas tais como o termo poder ser confuso para o público em geral, mas podem ser extremas como as que propõem sua extinção. (...) A análise desenvolvida leva à conclusão de que a herdabilidade, tanto pela genética do comportamento, quanto pela genética molecular, é útil para seus respectivos fins. Os autores consideram que ao invés de ser extinto, o termo pode ser utilizado considerando mais análises, resultados e conclusões, sendo, portanto, essa a escolha mais racional e progressiva.

The article discusses the following question: why has the traditional philosophy of science been reluctant to seriously deal with scientific controversies? An answer is offered and an alternative is suggested. This alternative gives a leading role to the study of controversies within the framework of the philosophy of science. This proposal is supported, firstly, by a brief review of the research methodology employed by Johannes Kepler and, secondly, by the study of the emergence of quantum mechanics by Mara Beller. The (...) defense of the study of controversies is based on the recognition of the other one as the founding point of scientific objectivity and in the proposal of a kind of triangulation. (shrink)

We obtain, for the first time, a modular many-valued semantics for combined logics, which is built directly from many-valued semantics for the logics being combined, by means of suitable universal operations over partial non-deterministic logical matrices. Our constructions preserve finite-valuedness in the context of multiple-conclusion logics, whereas, unsurprisingly, it may be lost in the context of single-conclusion logics. Besides illustrating our constructions over a wide range of examples, we also develop concrete applications of our semantic characterizations, namely regarding the semantics (...) of strengthening a given many-valued logic with additional axioms, the study of conditions under which a given logic may be seen as a combination of simpler syntactically defined fragments whose calculi can be obtained independently and put together to form a calculus for the whole logic, and also general conditions for decidability to be preserved by the combination mechanism.

En el Escolio acerca del “Espacio y el Tiempo”, Newton expone su concepción referida a un Espacio absoluto, elcual posee existencia tan real, como la de los demás cuerpos físicos pero en forma independiente de estos, es asíque una de las características de la física newtoniana‡ va a ser el interés por conceder una existencia independientey real al espacio y al tiempo, así como a la materia, ya que en las leyes del movimiento de Newton aparece elconcepto de aceleración, y (...) en esta teoría, la palabra aceleración sólo puede denotar “aceleración con respecto alespacio”. Por consiguiente, el espacio de Newton debe ser concebido “en reposo absoluto” o, al menos, con elfin de que sea posible considerar que la aceleración que aparece en las leyes del movimiento sea una “magnitud”o (fuerza), con algún significado. Por tal motivo, se propone: “distinguir el reposo y el movimiento tanto relativoscomo absolutos, por sus propiedades, causas y efectos.”. (shrink)

El objetivo de este trabajo consiste en explicar el concepto de «poder de lo real» en la filosofía de Xavier Zubiri. Siendo este el núcleo, hemos querido confrontar su reflexión con otros autores relacionados con un ámbito, digamos, artístico-filosófico. Autores en los que, como ocurre con el filósofo vasco, el poder de lo real, de las cosas reales concretas, es lo que proporciona el eje de sus obras. Es decir, el hombre abona, mediante ese poder, su funcionalidad con respecto a (...) las demás cosas reales, incluido el propio ser humano. Primeramente, nos introduciremos en la amplia reflexión que realiza Zubiri en relación a dos conceptos complejos, el de poder y el de lo real. Seguidamente nos adentraremos en la mirada trágica, con especial consideración a Edipo rey, de Sófocles, una obra que permite ver cómo ese poder se produce desde la vivencia trágica, lo que nos ayuda a comprender la perspectiva de Zubiri que también hace hincapié en el significado de la realidad trágica. El añadido del escritor Samuel Beckett se realiza porque su obra, en especial Esperando a Godot, puede servir de contraste, y al mismo tiempo de reto, a la visión zubiriana desde una perspectiva de la filosofía del absurdo.

Equal access to vaccines has been one of the key ethical challenges during the COVID-19 pandemic. Most scholars consider the massive purchase and hoarding of vaccines by high-income countries, especially at the beginning of the pandemic, to be unjust towards the vulnerable living in low-income countries. A recent proposal by Andreas Albertsen of a vaccine tax has been put forward to remedy this problem. Under such a scheme, high-income countries would pay a contribution, conceptualised as a vaccine tax, dedicated to (...) buying vaccines and distributing them to low and middle-income countries. Proceeding from this proposal, we critically assess the feasibility of a vaccine tax and suggest how to conceptualise and implement a vaccine tax in practice. We present our ‘VaxTax model’ and explore its comparative advantages and disadvantages while considering other possible measures to address the global vaccine access problem, also in view of future pandemics and disease outbreaks.

As a result of advances in healthcare, the worldwide average life expectancy is steadily increasing. However, this positive trend has societal and individual costs, not least because greater life expectancy is linked to higher incidence of age-related diseases, such as dementia. Over the past few decades, research has isolated various protective “healthy lifestyle” factors argued to contribute positively to cognitive aging, e.g., healthy diet, physical exercise and occupational attainment. The present article critically reviews neuroscientific evidence for another such factor, i.e., (...) speaking multiple languages. Moreover, with multiple societal stakeholders in mind, we contextualize and stress the importance of the research program that seeks to uncover and understand potential connections between bilingual language experience and cognitive aging trajectories, inclusive of the socio-economic impact it can have. If on the right track, this is an important line of research because bilingualism has the potential to cross-over socio-economic divides to a degree other healthy lifestyle factors currently do not and likely cannot.

A descriptive-exploratory analysis of assurance practices is presented in this paper, by analysing the patterns of sustainability assurance reporting in two national contexts with different levels of assurance activity over a period of 11 years. The study is based on theoretical insights drawn from institutional sociology and normativity production. It is framed both in the Italian situation, where assurance statements consistently include a narrow set of formal and procedural communications, and in an unsettled situation in the U.S., where assurance activity (...) is more incipient, but where experimentation in substantial assurance disclosure practices has more room to develop. Its main implication is that the diffusion of sustainability assurance and the creation of sustainability assurance disclosure norms are not without its cost: information quality does not increase with patterned practice. The results also point towards the noteworthy role of specific professionals in the earlier and later stages of assurance practice norms. They reveal a significant influence of non-Big4 firms in the diffusion of sustainability assurance disclosure norms. In contrast, the Big4 firms appear to be positively associated with the narrowing down of the assurance focus to a selected subset of this activity in later stages of the development of the assurance norm. In this regard, this study provides insight into the circumstantial—but relevant—carrier role of the Big4 firms in determining what “assurance” means. (shrink)

In recent years, some scholars have claimed that humans are unique in their capacity and motivation to engage in cooperative communication and extensive, fast-paced social interactions. While research on gestural communication in great apes has offered important findings concerning the gestural repertoires of different species, very little is known about the sequential organization of primates’ communicative behavior during interactions. Drawing on a conversation analytic framework, this paper addresses this gap by investigating the sequential organization of bonobo mother-infant interactions, and more (...) specifically, how individuals solicit carries from one another. It shows how bonobos establish participation frameworks before producing a carry request gesture and how the ensuing communicative actions can be organized in adjacency-pair sequences. Moreover, the timing between the initiation of an action and its response is similar to what has been documented in adult human interaction. Finally, it outlines some of the orderly practices bonobos use to deal with the absence of response from the addressed participants in carry sequences. Keywords: adjacency pair; pan paniscus; conversation analysis; gestures; interactional time; sequence organization. (shrink)
