El control efectivo de la calidad y seguridad de los ali­mentos requiere de métodos analíticos que garanticen la deter­minación fiable de cualquier sustancia potencialmente perjudicial para el consumidor que pueda estar presente en el alimento antes de su distribución y comercialización. Una de las aproximaciones analíticas que contribuye a garantizar este objetivo engloba una serie de técnicas que tienen en común la utilización de anticuerpos como elementos esenciales para la detección del analito diana, y que en conjunto reciben el nombre (...) de métodos inmunoquímicos. Este artículo pretender aportar una visión básica de los principios bioquímicos subyacentes a estas tecnologías y cuáles son sus venta­jas y limitaciones en la determinación de contaminantes químicos, residuos y aditivos en matrices alimentarias. En la última parte se comentan algunas de nuestras iniciativas en este ámbito que han dado lugar a kits rápidos disponibles comercialmente tras haber transferido la tecnología correspondiente al sector industrial.

Learning disabilities are highly prevalent on college campuses, yet students with learning disabilities graduate at lower rates than those without disabilities. Academic and psychosocial supports are essential for overcoming challenges and for improving postsecondary educational opportunities for students with learning disabilities. A holistic, multi-level model of campus-based supports was established to facilitate culture and practice changes at the institutional level, while concurrently bolstering mentors’ abilities to provide learning disability-knowledgeable support, and simultaneously creating opportunities for students’ personal and interpersonal development. Mixed (...) methods were used to investigate implementation of coordinated personal, interpersonal, and institutional level supports for undergraduate science, technology, engineering, and math (STEM) students with learning disabilities. A one-group pre-test post-test strategy was used to examine undergraduate outcomes. Participants included 52 STEM undergraduates with learning disabilities, 57 STEM graduate student mentors, 34 STEM faculty mentors, and 34 university administrators and personnel as members of a university-wide council. Enrolled for two years, undergraduates were engaged in group meetings involving psychoeducation and reflective discussions, development of self-advocacy projects, and individual mentorship. Undergraduates reported improved self efficacy (p =.001), campus connection (p <.001), professional development (p ≤.002), and self advocacy (p <.001) after two academic years. Graduate student mentors increased their understanding about learning disabilities and used their understanding to support both their mentees and other students they worked with. Council members identified and created opportunities for delivering learning disability-related trainings to faculty, mentors and advisors on campus, and for enhancing coordination of student services related to learning and related disorders. Disability-focused activities became integrated in broader campus activities regarding diversity. This research explicates a role that college campuses can play in fostering the wellbeing and the academic and career development of its students with developmental learning and related disorders. It offers an empirically tested campus-based model that is multilevel, holistic, and strengths-based for supporting positive outcomes of young people with learning disabilities in STEM. Moreover, findings advance the knowledge of supports and skills that are important for self-regulating and navigating complex and multi-faceted disability-related challenges within both the post-secondary educational environment and the young adults’ sociocultural context.

Following Alvesson and Kärreman's influential essay on the modes and interpretation of organizational discourse, this article reports on a longitudinal study of naturally occurring interactions that took place before, during, and after a meeting between representatives of Médecins sans Frontières, a well-known humanitarian organization, and representatives of local health centers in a region of the Democratic Republic of Congo. This episode is used to exemplify the fruitfulness of adopting a view that incorporates two dimensions of discourse, that is, what Alvesson (...) and Kärreman identify as its transient and muscular nature. The longitudinal aspect of our study allows us to show what interactants accomplish in particular settings, while illustrating a crucial aspect of the trans-local dimension of their talk. As shown in this article, a given Discourse must be embodied, materialized or even incarnated in discourses, that is, tokens of text or talk, in order for it to be reproduced, sustained and transported from one point to another, that is, to become what Latour calls an immutable mobile. A given Discourse can thus maintain its shape across time and space only if a lot of interactive work is done to assure the stability of its associations in the ordinary day-to-day activity of the people who embody it.

En la historia intelectual de América Latina existe una laguna respecto a la producción de las mujeres en el género de ensayo. Son los ensayos de identidad criolla, de hechura masculina, los que construyen el canon respecto a las temáticas y a las maneras de ser abordado. Los ensayos de género que las escritoras han realizado se articulan como respuesta a esta visión dominante de los procesos sociales, políticos y culturales de los países latinoamericanos. Revelan un fuerte descontento con la (...) construcción de la identidad femenina, una preocupación por la construcción de una ciudadanía plena y representan una respuesta a las demandas sociales políticas y culturales de las mujeres y otros grupos marginales. Las intelectuales debatieron, discutieron y polemizaron con las propuestas que al respecto portaban los discursos dominantes y el ensayo de género se vuelve el “arma de combate”. Lo que aquí se presenta, tiene como objetivo la recuperación de este corpus de conocimiento en la historia literaria de Cuba, Puerto Rico y República Dominicana. Una labor de arqueología literaria de temas, obras y autoras a partir del siglo XX. Se brinda, a partir del libro Mujeres ensayistas del Caribe Hispano: Hilvanando el silencio (2007) deAnna Freire Ashbaugh, Lourdes Rojas y Raquel Romeu, una visión panorámica del conjunto de ensayistas de cada país. Otras investigadoras como Catharina Vallejo, Ivette Sóñora, Carmen Dolores Hernández y Consuelo Meza Márquez ampliaran ese corpus y señalan algunos rasgos temáticos de la obra ensayística de autoras como Luisa Campuzano, Mirta Yáñez, Nara Araujo, Marta Núñez Sarmiento y Zaida Capote Cruz de Cuba; Concha Meléndez, Rosario Ferré, Norma Valle Ferrer, Nara Negrón Marreño y Silvia Álvarez Curbelo de Puerto Rico; y, de República Dominicana, Camila Henríquez Ureña, Carmita Landestoy, Carmen Durán y Rosa Inés Curiel Pichardo.

Este artículo se interroga acerca del papel que ha tenido la epistemología feminista en la emergencia de los estudios de género y salud. Al revisar la literatura internacional observamos una falta de evidencias de esa influencia intelectual: se cita raramente a las teóricas del feminismo, casi no hay uso explícito del termino feminismo, sustituido por el exitoso «sesgos de género» o «perspectiva de género», observándose similar silencio, incluso, en médicas significadas del movimiento feminista o reconocidas investigadoras de las redes de (...) estudios de género, en el caso español. En este contexto, y tras examinar varias hipótesis explicativas del fenómeno, se propone cambiar los criterios de evaluación y el escenario para centrarse en la praxis médica y las relaciones terapéuticas. Finaliza la nota planteando la verdadera cuestión: ¿está influyendo esa práctica médica en el feminismo?, ¿cómo saberlo? (shrink)

Moore and Russell’s philosophical and personal paths through the early years of the twentieth century make a fascinating chronicle. Some of this story is familiar; but material from the unpublished Moore papers adds new and forceful detail to the account. It is a commonplace by now that Russell and Moore were not friends, although they maintained a long professional association. Their most intellectually intimate phase came early on, reaching a peak in 1897–99. But I show that during this period Moore (...) developed an indisputable antagonism toward Russell, which I argue was motivated by a form of intellectual self-preservation from the Russellian juggernaut. This paper examines aspects of the development of their views and their relationship between 1894 and 1901. (shrink)

This paper proposes that Hannah Arendt’s book _Eichmann in Jerusalem: A Report on the Banality of Evil_ furnishes both philosophical and empirical elements to understand not only the Nazi crimes but also cases of wrongdoing by and within current organizations. It is suggested that Arendt provides three relevant standpoints to how wrongdoing is _banalized_ within organizations: a critique of bureaucratic administration, an account of the role of interactive socialization, and a reflection on the cognitive and meaning-attribution processes. Arendt originally connected (...) these three dimensions to _thoughtlessness_, understood as a process of routinization in which organizations discourage critical thinking, personal responsibility, and reflection about the ultimate meaning and consequences of actions and decisions. As opposed to this, thoughtfulness is proposed as an approach based on meaningful pursuit within organizations to avoid some of the normative, cognitive, and routine elements that encourage, justify, and reproduce the banalization of misconduct.

Analytic Philosophy: An Interpretive History explores the ways interpretation shaped the analytic tradition, from Frege to Dummet. It offers readers 17 chapters, written especially for this volume by an international cast of leading scholars. Some chapters are devoted to large, thematic issues like the relationship between analytic philosophy and other philosophical traditions such as British Idealism and phenomenology, while other chapters are tied to more fine-grained topics or to individual philosophers, like Moore and Russell on philosophical method or the history (...) of interpretations of Wittgenstein’s _Tractatus_. Throughout, the focus is on interpretations that are crucial to the origin, development, and persistence of the analytic tradition. The result is a more fully formed and philosophically satisfying portrait of analytic philosophy. (shrink)

I argue that Alisa Carse's call for antipornography legislation sets a potentially dangerous legal move that could threaten to shut off the dialogue women need to redefine the meanings and terms of our sexualities. I also argue that the terms of legitimacy need to be re-examined outside a legal system that systematically fails to protect the rights of sexual minorities.

En este trabajo se indaga en el comportamiento de la atenuación en los verbos que expresan duda, presentes en el corpus AMERESCO de conversaciones coloquiales de Santiago de Chile. Se describen las funciones de la atenuación de estos verbos de acuerdo con (1) el tipo de acto de habla, (2) la actividad de imagen y (3) algunas características sintáctico-discursivas. Los principales hallazgos demuestran que la atenuación se manifiesta a través de verbos doxásticos (_creer_, _parecer_, _cachar_, etc.), verbos modales (_poder_, _deber_) (...) y el verbo “saber” con polaridad negativa (“_no sé_”). Esta surge cuando se presenta lo dicho como una duda, bien para suavizar una opinión contraria o crítica, en cuyo caso su significado es de opinión, bien para informar sobre un estado de cosas, cuando su significado es epistémico. En el reconocimiento de su carácter atenuante, resultan clave el tipo de acto de habla en el que ocurren, el rol proyectado por el hablante en la conversación, la gestión de las imágenes y sus características sintáctico-discursivas, elementos que determinan si estas construcciones verbales expresan mayor o menor atenuación.

I argue that the familiar picture of the rise of analytic philosophy through the early work of G. E. Moore and Bertrand Russell is incomplete and to some degree erroneous. Archival evidence suggests that a considerable influence on Moore, especially evident in his 1899 paper ‘The nature of judgment,’ comes from the literature in nineteenth-century empirical psychology rather than nineteenth-century neo-Hegelianism, as is widely believed. I argue that the conceptual influences of Moore’s paper are more likely to have had their (...) source in the work of two of Moore’s teachers, G. F. Stout and James Ward. What may be called an anti-psychologism about psychology characterizes the work of these and other psychologists of the period. I argue that the anti-psychologism that is the main aim of Moore’s early theory of judgment is an adaptation of this notion, which is significantly dissimilar from the notion defended by Bradley, traditionally thought to have been a key influence on Moore.Keywords: G. E. Moore; Bertrand Russell; Propositions; Anti-psychologism; Early analytic philosophy; G. F. Stout. (shrink)

There has been little research on the vocabulary of the Greek novelists. Gasda studied that of Chariton in the last century. He compared some of his terms with those of other authors and he concluded he should be placed in the sixth century A.D. Then Schmid considered that Chariton's language was not Atticist, and dated his novel in the second century or beginning of the third. In 1973 Chariton's language was studied by Papanikolaou. His research dealt above all with several (...) syntactic aspects and the use of some vocabulary, which led him to conclude that this language was closer to the koiné than that of the other novelists. But Papanikolaou went further in his conclusions: finding no trace of Atticism in Chariton, he considered him a pre-Atticist writer and, using extra-linguistic data, such as the citing of the Seres, the Chinese , placed him in the second half of the first century B.C. This chronology has been accepted by some, but already Giangrande has observed that this lack of Atticisms could have been intentional, in which case that date would be questionable. (shrink)

Higher education in the 21st century faces the challenge of changing the way in which knowledge is conveyed and how teachers and students interact in the teaching-learning process. The current pandemic caused by SARS-CoV-2 has hastened the need to face up to this challenge and has furthered the need to approach the issue from the perspective of digitalisation. To achieve this, it is necessary to design training programmes geared towards teaching staff and which address both the use of technology and (...) instructional design aimed at promoting the development of self-regulated learning and automatic feedback systems. In this study, work was carried out with 23 teachers in a training programme conducted through Moodle. The aims were: to test whether there were any significant differences between the behaviour patterns of new teachers compared to experienced teachers, to determine whether clusters of behaviour patterns corresponded to the type of teacher and to ascertain whether the level of teacher satisfaction with the training activity in digital teaching will depend on the type of teacher. A quantitative as well as a qualitative design was applied. Differences were found in the behaviour patterns in the training activities for the development of rubrics and use of learning analytics systems in virtual learning environments. It was also found that the type of teacher did not correspond exactly to the behaviour cluster in the learning platform. In addition, no significant differences were found in the level of satisfaction between the two kinds of teacher. The main contribution this study makes is to provide a detailed description of the training stage as well as the materials required for its repetition. Further analytical studies are required on teacher perception of training programmes in digital teaching in order to provide personalised training proposals that lead to an effective use of teaching in digital environments.

La multiplicidad de iconos con los que se pretende atraer nuestra atención y poner a prueba nuestra voluntad en las sociedades actuales: iconos de la moda, de la canción, del arte, de la riqueza, del éxito, del poder, de las ideologías, de las profesiones, del ocio y tantos más, han quitado trascendencia a eso más grande a lo que debería conducir la imagen o el signo con que se nos muestran, a lo que buscan representar y a lo que significan. (...) La admiración que saben inspirarnos, la cercanía que produce su simbolismo, y la posibilidad de sopesar el elegirlos como camino para conmover una parte de nuestro interior y de nuestras decisiones, hace que, además de imponerse a nuestra mirada, reclamen adhesión y conformidad.

Can sociology comprehend evil? The contemporary relevance of Kurt H. Wolff’s sociology is his lucid, critical vision of modernity which does not shy away from understanding what evil is. This is accompanied not by pessimism, but by trust in human beings and their positive ability to appeal to the moral conscience. Read today, Wolff’s pages must be placed in the category of a new understanding of the human subject and the diagnosis of our time, the request for which threads in (...) and out of contemporary social theory. Awareness of history, rejection of sociological nominalism, emphasis upon the role of the human subject in an unprecedented situation: in Wolff, these themes converge and invite us to open ourselves to the re-enchantment of the world. After describing with some detail the main concepts of Wolff’s sociological theory and phenomenological approach, the paper suggests a reading of the re-enchantment of the world in terms of a sociological confrontation with evil, which has all too often been bypassed by sociology. We cannot grasp the evildoer's motivations from the perspective of an autonomous, rationally disengaged and masterful subject which tends to eclipse emotive and embodied senses of selfhood. By suspending the taken-for-granted definitions which exist in mainstream literature, by making an excruciating effort in looking at or reading detailed descriptions of evildoing, by assuming the victim’s suffering as part of our sociological explanation, we can start understanding what evil is today and in what way it is connected to modernity.

Business Ethics: A European Review, EarlyView.

: I argue that Alisa Carse's call for antipornography legislation sets a potentially dangerous legal move that could threaten to shut off the dialogue women need to redefine the meanings and terms of our sexualities. I also argue that the terms of legitimacy need to be re-examined outside a legal system that systematically fails to protect the rights of sexual minorities.

Externalistic theses about the nature of content appear to have untoward consequences for the role of content in folk pscyhological causal explanation. Given the predominance of Twin Earth formulations of externalism, however, the explanatory role problem is often construed as the problem of content's failure to supervene on intrinsic states of the head. In this paper I argue that this is misleading. The most general formulation of externalsim is shown to be independent of any supervenience claims. The result is that (...) all concepts can be shown to be both externalist in individuation and irrelevant in causal explanation, whether or not they fail to supervene on intrinsinc states. (shrink)
