Rabern and Rabern (Analysis 68:105–112 2 ) and Uzquiano (Analysis 70:39–44 4 ) have each presented increasingly harder versions of ‘the hardest logic puzzle ever’ (Boolos The Harvard Review of Philosophy 6:62–65 1 ), and each has provided a two-question solution to his predecessor’s puzzle. But Uzquiano’s puzzle is different from the original and different from Rabern and Rabern’s in at least one important respect: it cannot be solved in less than three questions. In this paper we solve Uzquiano’s puzzle (...) in three questions and show why there is no solution in two. Finally, to cement a tradition, we introduce a puzzle of our own. (shrink)

We explore the distinctive characteristics of Mexico's society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934-1940), which was primarily directed towards improving (...) the condition of small Mexican farmers. Taboada is the first Mexican post-graduate investigator in phytotechnology and phytopathology, trained at Cornell University and the University of Minnesota, in 1932 and 1933, respectively. He was the first investigator to teach plant genetics at the National School of Agriculture and wrote the first textbook of general genetics, Genetics Notes, in 1938. Taboada's most important single genetics contribution was the production of "stabilized" corn varieties. The extensive exile of Spanish intellectuals to Mexico, after the end of Spain's Civil War (1936-1939), had a major influence in Mexican science and characterizes the second stage. The three main personalities contributing to Mexican genetics are Federico Bonet de Marco and Bibiano Fernández Osorio Tafall, at the National School of Biological Sciences, and José Luis de la Loma y Oteyza, at the Chapingo Agriculture School. The main contribution of the Spanish exiles to the introduction of genetics in Mexico concerned teaching. They introduced in several universities genetics as a distinctive discipline within the biology curriculum and wrote genetics text books and manuals. The third stage is identified with Alfonso León de Garay, who founded the Genetics and Radiobiology Program in 1960 within the National Commission of Nuclear Energy, which had been founded in 1956. The Genetics and Radiobiology Program rapidly became a disciplinary program, for it embraced research, teaching, and training of academics and technicians. The Mexican Genetics Society, created by de Garay in 1966, and the development of strains and cultures for genetics research were important activities. One of de Garay's key requirements was the compulsory training of the Program's scientists for at least one or two years in the best universities of the United States and Europe. De Garay's role in the development of Mexican genetics was fundamental. His broad vision encompassed the practice of genetics in all its manifestations. (shrink)

El siguiente informe pericial se basa en la experiencia de investigación de los firmantes en relación a las exhumaciones de fosas comunes de la Guerra Civil y la postguerra, y al conocido como “movimiento para la recuperación de la memoria histórica” que están teniendo lugar en España desde el año 2000, que ha enfatizado sus demandas sobre la suerte de los desaparecidos y ha puesto en marcha un ciclo de exhumaciones de fosas comunes derivadas de la Guerra Civil y la (...) dictadura. En este peritaje se usan las exhumaciones del siglo XXI como indicadores de la persistencia en el tiempo de las políticas y culturas del miedo instaladas en la sociedad española durante la Guerra Civil y la dictadura, más allá de las profundas transformaciones políticas e institucionales acaecidas en el país tras la muerte de Francisco Franco. Fue presentado como parte de la documentación de la demanda de Fausto Canales contra España el 15 de septiembre de 2012 en el Tribunal Europeo de Derechos Humanos. (shrink)

A leading authority in contemporary and digital photography places images of the transitions of American cities in the 1980s and 1990s beside Sartre's meditative essays based on an extended visit to America in 1945, in a volume originally published as part of The Aftermath of War.

Specific classes of cyberspaces emphasize different types of digital transactions given the user’s context, thus making it essential to take into account what these environments can afford. In this way, we can portray the niches of technological use as ecologies of particular possibilities and compare how they differ between distinct spheres of human life. The present research is focused on describing the conceptual integration of a taxonomic crossover between Virtual Learning Environments and Educational Affordances of Technology, while also performing empirical (...) testing and determining the psychometric properties in a scale regarding the aforementioned taxonomy. The study sample consisted of 320 students in the departments of foreign languages from three different universities in Sonora. Students were given a questionnaire of 21 items organized into four subscales with a Likert-type response option to measure the notions concerning their usage of Virtual Learning Environments. Internal consistency procedures and confirmatory factor analysis by means of Cronbach’s alpha and Structural modeling support the derived factorial structure, which contains Cyber-Communications, Virtual Behavior Settings, Virtual Communities, and Availability and Access to Connectivity. This structure traces the environmental properties perceived by learners in a virtual environment. Results sustain the initial conceptual construction regarding the proposed taxonomy, conclude that the ‘Virtual Learning Environments Questionnaire’ demonstrates adequate psychometric properties, and validate it as a fitting measure to assess the perceived psychological experience of students in a digital educational setting.

"La persona es un valor por sí misma"; esta frase enunciada por Max Scheler puede servir para enfrentar el análisis de su concepto de persona como un valor en sí misma y por sí misma, no sólo a nivel individual, sino también social, analizando su exposición descriptiva del sentido de la afirmación uncida al amor, siendo éste su valor primordial. En este sentido, el amor preside la vida de la persona, la sostiene y la lleva a su plenitud.Palabras llave: Max (...) Scheler; valor; persona; metaantropología; amor."A person is a value in and of itself"; this phrase announced by Max Scheler can help to confront the analysis of the concept of the person as a value in itself, and by itself, not only on an individual level but also on a social one, analyzing his descriptive exposition of sense in the affirmation under the bondage of love, since this is its primary value. In this sense love presides over the life of a person, it sustains him and leads him to his full realization.Palabras llave: Max Scheler; value; person; metaanthropology; love. (shrink)

In spite of the considerable development of research in the fields of business ethics and family business, a comprehensive review and integration of the area where both disciplines intersect has not been undertaken so far. This paper aims at contributing to the call for more research on family business ethics by answering the following research questions: What is the status of the current research at the intersection of business ethics and family business? Why and how do family firms differ from (...) non-family firms regarding business ethics? And, what are the key directions for further research? To answer these questions, this study combines a systematic approach for the selection of articles, resulting in a sample of 31 articles over 35 years, with a narrative review to analyze the literature. This paper finds that research on family business ethics is scarce but increasing and that family firms are considerably different from non-family firms regarding ethical issues. Particular stakeholders, goals, relationships, and practices are found to be the forces behind the peculiarity of family business ethics. Ultimately, research development on family business ethics is encouraged and future research directions flowing from the key findings and reflections of this review are provided. (shrink)

O artigo parte de uma aproximação à sura 19 para problematizar a forma convencional de se compreenderem a formação do Corão e as origens do islã. Por uma análise rápida dos materiais e das fontes que mostram o texto mostra como as teorias tradicionais sobre o surgimento de ambos são inadequadas porque não consideram a dinâmica e a vitalidade da cultura, bem como o complexo quadro das tradições religiosas presentes no Oriente Médio dos tempos da Antiguidade tardia, especialmente aquelas que (...) de alguma forma poderiam ser nomeadas judias ou cristãs. E propõe que do interior daquilo que se costuma chamar judeu-cristianismo emergem tanto um quanto outro. (shrink)

The purpose of the present study is to examine the attitudes of Portuguese chartered accountants with respect to questions of ethical nature that can arise in their professional activity. Respondents were asked to respond to the Ethics Position Questionnaire developed by Forsyth (Journal of Personality and Social Psychology 39(1), 175–184, 1980), in order to determine their idealism and relativism levels. Subsequently, they answered questions about five scenarios related to accounting practices, with the objective of measuring their ethical judgments. Based on (...) the idealism and relativism levels of our respondents, they were classified into one of four groups, representing different ethical ideologies (absolutism, exceptionism, subjectivism, and situationism). The results indicated that age was the major determinant of relativism. Contrary to previous research, older respondents revealed themselves significantly more relativistic than younger ones. Gender seems to be the most important determinant of ethical judgments; against expectations, men evidenced significantly stricter judgments than women in two of the five scenarios. Findings also indicated that respondents’ ethical judgments did not differ significantly based on their ethical ideology, supporting the idea that ethical ideology is not an important determinant of ethical judgments.

For many years to come, race will continue to be a source of controversy and conflict in American society. For many of us it will continue to shape where we live, pray, go to school, and socialize. We cannot simply wish away the existence of race or racism, but we can take steps to lessen the ways in which the categories trap and confine us. Educators, who should be committed to helping young people realize their intellectual potential as they make (...) their way toward adulthood, have a responsibility to help them find ways to expand identities related to race so that they can experience the fullest possibility of all that they may become. In this brutally honest—yet ultimately hopeful— book Pedro Noguera examines the many facets of race in schools and society and reveals what it will take to improve outcomes for all students. From achievement gaps to immigration, Noguera offers a rich and compelling picture of a complex issue that affects all of us. (shrink)

In this review, we describe some of the central philosophical issues facing origins-of-life research and provide a targeted history of the developments that have led to the multidisciplinary field of origins-of-life studies. We outline these issues and developments to guide researchers and students from all fields. With respect to philosophy, we provide brief summaries of debates with respect to (1) definitions (or theories) of life, what life is and how research should be conducted in the absence of an accepted theory (...) of life, (2) the distinctions between synthetic, historical, and universal projects in origins-of-life studies, issues with strategies for inferring the origins of life, such as (3) the nature of the first living entities (the “bottom up” approach) and (4) how to infer the nature of the last universal common ancestor (the “top down” approach), and (5) the status of origins of life as a science. Each of these debates influences the others. Although there are clusters of researchers that agree on some answers to these issues, each of these debates is still open. With respect to history, we outline several independent paths that have led to some of the approaches now prevalent in origins-of-life studies. These include one path from early views of life through the scientific revolutions brought about by Linnaeus (von Linn.), Wöhler, Miller, and others. In this approach, new theories, tools, and evidence guide new thoughts about the nature of life and its origin.We also describe another family of paths motivated by a” circularity” approach to life, which is guided by such thinkers as Maturana & Varela, Gánti, Rosen, and others. These views echo ideas developed by Kant and Aristotle, though they do so using modern science in ways that produce exciting avenues of investigation. By exploring the history of these ideas, we can see how many of the issues that currently interest us have been guided by the contexts in which the ideas were developed. The disciplinary backgrounds of each of these scholars has influenced the questions they sought to answer, the experiments they envisioned, and the kinds of data they collected. We conclude by encouraging scientists and scholars in the humanities and social sciences to explore ways in which they can interact to provide a deeper understanding of the conceptual assumptions, structure, and history of origins-of-life research. This may be useful to help frame future research agendas and bring awareness to the multifaceted issues facing this challenging scientific question. (shrink)

In this paper I assess the adequacy of no-conspiracy conditions employed in the usual derivations of the Bell inequality in the context of EPR correlations. First, I look at the EPR correlations from a purely phenomenological point of view and claim that common cause explanations of these cannot be ruled out. I argue that an appropriate common cause explanation requires that no-conspiracy conditions are reinterpreted as mere common cause-measurement independence conditions. In the right circumstances then, violations of measurement independence need (...) not entail any kind of conspiracy (nor backwards in time causation). To the contrary, if measurement operations in the EPR context are taken to be causally relevant in a specific way to the experiment outcomes, their explicit causal role provides the grounds for a common cause explanation of the corresponding correlations.

Este artigo tematiza o apóstolo Pedro como personagem no evangelho de Mateus. O objetivo é identificar as nuances e transformações do personagem Pedro no evangelho. Para tanto, tomo como ponto de partida a pertença do evangelho ao gênero literário biografia greco-romana, que apresenta Jesus Cristo como protagonista. Os demais personagens são desenvolvidos em relação com ele. O mesmo se dá com o apóstolo Pedro. O texto se desenvolve a partir da teoria narrativa, de modo particular a caracterização (...) de personagens. Identifico, a partir de Erich Auerbach e Robert Alter, as características de personagens bíblicos, tecendo comparações com teorias do personagem no romance moderno. A análise de textos do evangelho de Mateus que retratam o personagem Pedro leva à conclusão que suas principais características são a complexidade e a inversão. Elas produzem uma visão geral da involução do personagem na narrativa do evangelho de Mateus. Palavras-chave: Pedro. Evangelho de Mateus. Teoria narrativa. Complexidade. Inversão.This article focuses on the apostle Peter as a character in the Gospel of Matthew. It aims at identifying the nuances and changes of the character Peter in the Gospel. For this purpose, I take as a starting point that the gospel belongs to the literary genre of ancient Greco-Roman Biography, which presents Jesus Christ as the protagonist. The other characters are developed in relationship with him. The same is true with the Apostle Peter. The article unfolds from narrative theory, in particular the categorization of characters. I categorize, based on Erich Auerbach and Robert Alter, the features of biblical characters, developing comparisons with theories of the character in the modern novel. The analysis of the main texts from the Gospel of Matthew that portray the character Peter leads to the conclusion that its main features are complexity and inversion. They produce an overview of the involution of the character in the narrative of the Gospel of Matthew. Key words: Peter. Gospel of Matthew. Narrative theory. Complexity. Inversion. (shrink)

The interest in ethical leadership has grown in the past few years, with an emphasis on the mechanisms through which it affects organizational life. However, research on the boundary conditions that limit and/or enhance its effectiveness is still scarce, especially concerning one of the main misconceptions about ethical leadership, its incompatibility with effectiveness . Thus, the present study examines the relationship between ethical leadership and organizational deviance via affective commitment to the organization, as a reflection of the quality of the (...) employee–organization relationship and proposes this relationship is conditional on the supervisor’s personal reputation for performance . Using a sample of 224 employees and their respective supervisors from 18 organizations, we confirmed our hypotheses . Our findings suggest that ethical leadership is positively related to employees’ affective commitment to the organization, particularly when supervisor’s reputation for performance is high, which in turn is associated with decreased organizational deviance. The theoretical and practical implications of these findings conclude the paper. (shrink)

Pedro Sanchez de Acre, born at the beginning of the 16th century, was a prebendary of the cathedral of Toledo. He wrote three books about moral philosophy: Tree of Consultation and Varied Teaching in 1584, Moral and Philosophical Histor y in 1590 and Triangle of the Three Theological Virtues in 1595. These three books, representative of Miscellany, one of the most editorially successful literary genres of the 16th century, have become completely unknown with the passing of time. Besides the (...) rare quotation, used mostly in writings of a bibliographic nature, the presence of these books in Spanish philosophy is almost nonexistent. (shrink)

The history of Spain in the 20th and 21st century provides us with many examples of mimetic rivalry: the permanent conflict between peoples who inhabit a common territory, seeking their identity through the affirmation of differences. In the never-ending reciprocities that occur throughout the decades, with ferocious feuding between the left and right wings, and disputes between nationalities, we appreciate how the Girardian theses shine some light on conflictive and at times bloody relationships that would be difficult to understand without (...) the illuminating mimetic theory and the scapegoat mechanism.Mimetic theory and the scapegoat mechanism, together with some of Girard's most innovative intuitions (passion for...

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)

This article seeks to show how several rhetorical tools were used and, in fact, played a central role in the argumentation advanced by Niles Eldredge and Stephen Jay Gould in their 1972 seminal article on the theory of Punctuated Equilibria. It is analyzed how Eldredge and Gould proceeded through three steps that, sequentially integrated, made their argument compelling. It is shown how they made use of analogies, metaphors and other rhetorical tools. It is sustained that they began by priming the (...) reader to distrust the current interpretation of the fossil record offered by most paleontologists and then, in a second step, they used specific visual representations in order to suggest that the competitor theory was committed to the idea of an even and slow evolution at a constant rate, an image utilized by them as straw man. Finally, it is analyzed how, in their third step, Eldredge and Gould made use of several rhetorical arguments to present their theory as new for paleontology while, at the same time, placing it well inside the frame of the modern synthesis, and how they also managed to present their theory as more promising and capable of making predictions for future researches than the competitor theory.

The emergence and development of 'national sciences' in Latin American countries were not, until very recently, part of the agenda of historians of science because the 'traditional' history of sciences was not interested in the scientific activity of peripheral areas. The history of science is a recent discipline in Mexican historiographic studies. The methodological interest in the history of science, the creation of schools and institutes that deal with it, the establishment of particular chairs, the organization of national societies, and (...) the publication of books and periodicals are all very recent. It is important to carry out studies in the history of science that examine the development of Mexican science introducing the 'local' context, and study how this development has influenced the formation of scientific societies and the development of scientific disciplines in the country. We want to explore the introduction of genetics in Mexico as applied to agriculture between 1930 and 1960. This matter has not been investigated in Mexico and therefore this work would represent one of the first studies of this subject and one of the first studies in the general field of Mexican scientific history.

Este trabajo analiza las dos tesis principales del reciente libro de Manuel Pérez Otero, Vericuetos de la filosofía de Wittgenstein: la revisión de la simetría general entre acciones y omisiones como comportamientos intencionales, y la propuesta de respuesta disposicional “teleológica” al desafío escéptico sobre el significado del Wittgenstein de Kripke. Sobre la primera tesis, ponemos de manifiesto la neutralidad la gramática de la atribución de comportamientos intencionales respecto al determinismo causal, destacando el carácter retrospectivo implicado por el concepto de “justificación (...) post hoc”. Sobre la segunda, indicamos el rechazo del internismo no alcanza para hacer de las disposiciones teleológicas una explicación satisfactoria del comportamiento. Intentamos clarificar la clase de problema planteado por el escepticismo semántico wittgensteiniano: el abandono de la concepción que ve al seguimiento de reglas como la “praxis de un sujeto” por otra que ve a los seguidores de reglas como los “sujetos de una práctica”.

The icon is the type of sign connected to efficient representational features, and its manipulation reveals more information about its object. The London Underground Diagram (LUD) is an iconic artifact and a well-known example of representational efficiency, having been copied by urban transportation systems worldwide.

We stress that a specialized representation is an icon of the formal structure of the problem for which it has (...) been specialized. By embedding such rules of action and behavior, the icon acts as a semiotic artifact distributing cognitive effort and participating in niche construction. (shrink)
