Understanding the causes of maize landrace loss in farmers’ field is essential to design effective conservation strategies. These strategies are necessary to ensure that genetic resources are available in the future. Previous studies have shown that this loss is caused by multiple factors. In this longitudinal study, we used a collection of 93 maize landrace accessions from Morelos, Mexico, and stored at the International Maize and Wheat Improvement Center Maize Germplasm Bank, to trace back to the original 66 donor families (...) after 50 years and explore the causes for why they abandoned or conserved their seed lots. We used an actor-centered approach, based on interviews and focus group discussions. We adopt a Multi-Level Perspective framework to examine loss as a process, accommodating multiple causes and the interactions among them. We found that the importance of maize landrace cultivation had diminished over the last 50 years in the study area. By 2017, 13 families had conserved a total of 14 seed lots directly descended from the 1967 collection. Focus group participants identified 60 accessions that could still be found in the surrounding municipalities. Our findings showed that multiple interconnected changes in maize cultivation technologies, as well as in maize markets, other crop markets, agricultural and land policies, cultural preferences, urbanization and climate change, have created an unfavorable environment for the conservation of maize landraces. Many of these processes were location- and landrace-specific, and often led to landrace abandonment during the shift from one farmer generation to the next. (shrink)

Despite the increase in the research field of ethics in artificial intelligence, most efforts have focused on the debate about principles and guidelines for responsible AI, but not enough attention has been given to the “how” of applied ethics. This paper aims to advance the research exploring the gap between practice and principles in AI ethics by identifying how companies are applying those guidelines and principles in practice. Through a qualitative methodology based on 22 semi-structured interviews and two focus groups, (...) the goal of the current study is to understand how companies approach ethical issues related to AI systems. A structured analysis of the transcripts brought out many actual practices and findings, which are presented around the following main research topics: ethics and principles, privacy, explainability, and fairness. The interviewees also raised issues of accountability and governance. Finally, some recommendations are suggested such as developing specific sector regulations, fostering a data-driven organisational culture, considering the algorithm’s complete life cycle, developing and using a specific code of ethics, and providing specific training on ethical issues. Despite some obvious limitations, such as the type and number of companies interviewed, this work identifies real examples and direct priorities to advance the research exploring the gap between practice and principles in AI ethics, with a specific focus on Spanish companies.

El jaramillismo fue y es, puesto que aún existen decenas o centenas de labriegos que se reclaman jaramillistas, un movimiento social, prioritariamente agrario, que se ubica específicamente en el estado de Morelos y partes de Puebla y Guerrero. La figura de un excapitán del Ejército Libertador del Sur, se va a convertir en el principal impulsor de las diversas luchas en las que participan los campesinos sureños organizados en torno a Rubén Jaramillo. El enfrentamiento con los sectores hegemónicos del Estado (...) de Morelos, abarca desde los lejanos años veintes, hasta el asesinato de su dirigente en 1962. Todas las tácticas fueron empleadas por esta tendencia rural, la demanda de tierras y créditos, la formación de cooperativas de producción y consumo, las huelgas en el ingenio de Zacatepec, la fundación de un partido político, con la finalidad de participar en procesos electorales y cuando se cerraban las opciones, la lucha armada. Siempre pugnando por que se cumplieran los postulados agraristas del Plan de Villa de Ayala y desde luego, del contenido del artículo 27 constitucional. Nunca fueron resueltos los problemas sociales, políticos y económicos, que presentaba Rubén Jaramillo en su incansable confrontación con los grupos hegemónicos y su representante el partido oficial PRI. A pesar de contar con una amnistía que le había otorgado el gobierno de Adolfo López Mateos, el dirigente social, fue acribillado en unión de su familia en la zona arqueológica de Xochicalco en mayo de 1962. Una vez más el sistema político de esta nación, había deshonrado su palabra Palabras clave: Jaramillismo, nacionalismo revolucionario, clandestino, guerrilla, hegemonía. (shrink)

Jane Austen normally avoids discussing appearance throughout her works. Persuasion constitutes the exception to the rule, as the story focuses on the premature aging experienced by her protagonist, Anne Elliot, seemingly due to disappointed love. Much has been written about Anne’s “loss of bloom,” but never from the perspective of psychoneuroimmunology, the field that researches the interrelation between psychological processes and the nervous and immune systems. In this paper, we adopt a perspective of psychoneuroimmunology to argue that Austen established a (...) connection between psychological distress, specifically lovesickness, and the development of early senescence signs, and vice versa, since the recovery of love is associated with happiness and physical glow. From a gender perspective, we discuss how Austen brightly reflected these interrelationships through the story of Anne, when the latest psychoneuroimmunological research has actually shown that women age earlier than men as a consequence of psychological turmoil.

Dynamic Theodicy (DT) is a broad concept we bring up to designate some modern Philosophical Theology attempts to reconcile the necessary and perfect existence of God with the contingent characteristics of human life. In this paper we analyze such approaches and discuss how they have become incomprehensible because the metaphysical assumptions implicit in these explanations have lost their intrinsic relation to the natural human desire for salvation. In the first part we show Charles Hartshorne's DT-model, arising from the modal logic (...) of perfection, and the modern rational problems of this position in making infinite-necessary Being (God) and finite-contingent being (human) compatible. We note that at the heart of the contradictions in this DT account is a dialectical mode of thinking that makes it difficult to find a correct solution to this dichotomy, and to assume a human desire that could be considered related to lifelong goals. In the second part, supported by the proposal of Hans Urs von Balthasar's DT, we develop the concepts of bodily vulnerability, corporeal intentionality, and natural desire for salvation, which come from an Aristotelian-Thomistic thought. This theory is established in order to build an argument, following Alasdair MacIntyre’s ethical framework, on how to make possible the recovery of a metaphysical and anthropological desire that transcends natural aging and goes beyond death. We conclude that both human dependence and the virtues that arise naturally when human beings decide to seek the good of their transcendent condition, make it possible to recover the natural desire for salvation through divine and human love.

Food Services generate solid waste from the production process and distribution of meal. The raw material, after a rational flow, is transformed into meals for consumption generating solid waste of variable composition and quantity. Waste recovery actions in the recycling and selective collection in these services act as inhibitors of the inadequate disposal of these wastes in the environment, contributing to environmental sustainability. The objective of this study is to analyze the generation and viability of commercialization of recyclable solid waste (...) in Food Services of companies located in Cuiabá and Várzea Grande, Mato Grosso – Brazil. This is a cross-sectional exploratory study with a convenience sample. The analysis of the generation of residues was carried out using the weighing method and generation indices using descriptive statistics. In order to verify the economic potential of recyclable waste, the value of intermediate consumption was used and sales price data were obtained by means of the publication "Compromisso Empresarial para Reciclagem" CEMPRE. It was found that in six services the largest part of waste was made of plastic, and in two services it was paper and cardboard. The generation of aluminum was more significant in one service, being the residue that added more economic value in the commercialization. The generation of glass and tetra pack packaging were not significant, and the recycling of both is not of interest to the scavengers. The results indicate that the commercialization of recyclable solid waste is viable. (shrink)

Both philosophers and psychologists have argued for the existence of distinct kinds of explanations, including teleological explanations that cite functions or goals, and mechanistic explanations that cite causal mechanisms. Theories of causation, in contrast, have generally been unitary, with dominant theories focusing either on counterfactual dependence or on physical connections. This paper argues that both approaches to causation are psychologically real, with different modes of explanation promoting judgments more or less consistent with each approach. Two sets of experiments isolate the (...) contributions of counterfactual dependence and physical connections in causal ascriptions involving events with people, artifacts, or biological traits, and manipulate whether the events are construed teleologically or mechanistically. The findings suggest that when events are construed teleologically, causal ascriptions are sensitive to counterfactual dependence and relatively insensitive to the presence of physical connections, but when events are construed mechanistically, causal ascriptions are sensitive to both counterfactual dependence and physical connections. The conclusion introduces an account of causation, an "exportable dependence theory," that provides a way to understand the contributions of physical connections and teleology in terms of the functions of causal ascriptions.

This thought-provoking book explores the multifaceted phenomenon of objectivity and its relations to various aspects of the law and practical reasoning. Featuring contributions from an international group of researchers from differing legal contexts, it addresses topics relevant not only from a theoretical point of view but also themes directly connected with legal and judicial practice. Beginning with an introduction from the editors proposing a new account of the meaning of objectivity, the book is then divided into three broad themes illuminated (...) by this account. Chapters first address a range of problems linked to the relationship between objectivity and jurisprudence, before turning in the second part to an analysis of the functions of objectivity in legal interpretation. The final part then deals with the function of objectivity in practical reasoning. Offering a spectrum of scholarly insights within a coherent intellectual framework, this book will be a crucial read for scholars and graduate students of legal philosophy and legal theory. Its discussion of objectivity as it relates to legal practice and practical reasoning will also be of interest to practitioners such as judges, arbitrators and lawyers. (shrink)

This Very Short Introduction explores the philosophical ideas and political theories of Hannah Arendt (1906-1975). As a survivor of the Holocaust, Arendt's life informed her work exploring the meaning and construction of power, evil, totalitarianism, and direct democracy. Through insightful readings of Arendt's best-known works, from The Origins of Totalitarianism (1951) to The Life of the Mind (1978), Dana Villa traces the importance of Arendt's ideas for today's reader. In so doing, Villa explains how Arendt gained world-wide fame (...) with the publication of Origins, and went on to have a distinguished career as a political theorist and public intellectual. A sometimes controversial figure, Arendt is now recognised as one of the most important political thinkers of the twentieth century and her works have become an acknowledged part of the Western canon of political theory and philosophy"--From the publisher.

El artículo busca revelar como resultado el papel de la comunicación de la innovación social en el comportamiento del usuario, si este modifica su intención de consumir un producto o servicio, cuando conoce que la empresa que oferta el bien o servicio tiene una práctica de innovación social implementada. Para responder al objetivo se formularon dos hipótesis que fueron testeadas mediante la aplicación de una encuesta basada en una muestra de conveniencia, que recolectó 300 respuestas en toda América Latina. Los (...) resultados obtenidos permiten suponer que el consumidor en Latinoamérica, en general, no solo quiere tener más información disponible y accesible (tanto en términos de accesibilidad de medios como de lenguaje), sino que quiere involucrarse, ser escuchado y poder intervenir en la comunidad; ya sea por iniciativa propia o alentado por las marcas y empresas en general.

Unscharfe Grenzen und fließende Übergänge kommen in allen Registern der Erfahrung vor. Von einer positiven Unbestimmtheit kann indes nur dort die Rede sein, wo diese gleichsam zur Sache selbst gehört und nicht nur unserem begrenzten Erkenntnisstand oder mangelnden Realisierungsmöglichkeiten zuzu-rechnen ist. Die gewachsene technologische Verfügungsmacht des Menschen, die sich mittlerweile auf die menschliche Lebenssubstanz selbst erstreckt, hat zu tiefgreifenden Veränderungen des Naturbegriffs geführt, in deren Verlauf die Grenzen zwischen Naturprodukten und Artefakten ständig verschoben werden. Damit tauchen neue Formen von Unbestimmtheit (...) auf, deren begriffliche Bewältigung uns vor besondere Probleme stellt. Wann genau beginnt das zu schützende menschliche Leben? Sind Hirntote wirklich tot? Kann ich eine Gehirntransplantation überleben, meine Existenz sogar in einem Klon fortsetzen? (shrink)

Early in animal development, gradients of secreted morphogenic molecules, such as Sonic hedgehog (Shh), Wnt and TGFβ/Bmp family members, regulate cell proliferation and determine the fate and phenotype of the target cells by activating well‐characterized signalling pathways, which ultimately control gene transcription. Shh, Wnt and TGFβ/Bmp signalling also play an important and evolutionary conserved role in neural circuit assembly. They regulate neuronal polarization, axon and dendrite development and synaptogenesis, processes that require rapid and local changes in cytoskeletal organization and plasma (...) membrane components. A key question then is whether morphogen signalling at the growth cone uses similar mechanisms and intracellular pathway components to those described for morphogen‐mediated cell specification. This review discusses recent advances towards the understanding of this problem, showing how Shh, Wnt and TGFβ/Bmp have adapted their ‘classical’ signalling pathways or adopted alternative and novel molecular mechanisms to influence different aspects of neuronal circuit formation.

The COVID-19 outbreak has ravaged all societal domains, including education. Home confinement, school closures, and distance learning impacted students, teachers, and parents’ lives worldwide. In this study, we aimed to examine the impact of COVID-19-related restrictions on Italian and Portuguese students’ academic motivation as well as investigate the possible buffering role of extracurricular activities. Following a retrospective pretest–posttest design, 567 parents reported on their children’s academic motivation and participation in extracurricular activities. We used a multi-group latent change score model to (...) compare Italian and Portuguese students’: pre-COVID mean motivation scores; rate of change in motivation; individual variation in the rate of change in motivation; and dependence of the rate of change on initial motivation scores. Estimates of latent change score models showed a decrease in students’ motivation both in Italy and in Portugal, although more pronounced in Italian students. Results also indicated that the decrease in students’ participation in extracurricular activities was associated with changes in academic motivation. Furthermore, students’ age was significantly associated with changes in motivation. No significant associations were found for students’ gender nor for parents’ education. This study provides an important contribution to the study of students’ academic motivation during home confinement, school closures, and distance learning as restrictive measures adopted to contain a worldwide health emergency. We contend that teachers need to adopt motivation-enhancing practices as means to prevent the decline in academic motivation during exceptional situations. (shrink)

The issue of how to incorporate the individual's first‐hand experience of illness into broader medical understanding is a major question in medical theory and practice. In a philosophical context, phenomenology, with its emphasis on the subject's perception of phenomena as the basis for knowledge and its questioning of naturalism, seems an obvious candidate for addressing these issues. This is a review of current phenomenological approaches to medicine, looking at what has motivated this philosophical approach, the main problems it faces and (...) suggesting how it might become a useful philosophical tool within medicine, with its own individual, but interrelated, contribution to make to current medical debates. After the general background, there is a brief summary of phenomenological ideas and their current usage in a medical context. Next is a critique of four key claims within current phenomenological medical works, concerning both the role phenomenology plays and the supposedly clear divide between phenomenology and other approaches. There are significant problems within these claims, largely because they overlook the complexity of the questions they consider. Finally, there is some more in‐depth examination of phenomenology itself and the true complexity of phenomenological debate concerning subjectivity. The aim is to show that it will be both more productive and truer to phenomenology itself, if we use phenomenology as a philosophical method for explicating and gaining deeper understanding of complex and fundamental problems, which are central to medicine, rather than as providing simple, but flawed solutions.

Educational policy and social sciences researchers have been studying dishonest behaviors among students for a long time. In this bibliometric study we examine the extant literature on academic dishonesty until 2017. We also analyze the specific case of the literature on plagiarism since it is arguably one of the most common academic dishonest behavior. We aim at identifying the intellectual structure of the field of academic dishonesty and plagiarism. Results show that Donald L. McCabe and Richard L. Marsh appear as (...) the most productive authors. Furthermore, Whitley, 235–274, 1998) “Factors associated with cheating among college students: A review”, and Pennycook, 201–230, 1996), entitled “Borrowing others’ words: Text, ownership, memory, and plagiarism” are the most cited publications on academic dishonesty and on plagiarism, respectively. Additionally, a strong connection between the McCabe and Treviño articles emerged from the co-citation analysis on academic dishonesty, and also a strong relationship between Pennycook, 201–230, 1996) and Pecorari, 317–345, 2003), suggesting that these articles are strongly connected. Results suggest that these are the most influential authors and articles of the field. (shrink)
