Orientar la escritura a través del currículo en la universidad

La escritura es ampliamente reconocida como una competencia fundamental en la formación académica y profesional. Los modos de escribir en la universidad implican la apropiación de formas específicas de aprender y de comunicarse en cada disciplina, por lo que difieren considerablemente de los modos de escribir en otros niveles educativos. De allí que su enseñanza y aprendizaje sea responsabilidad de toda la comunidad universitaria. Este libro tiene como propósito ofrecer herramientas para que los profesores de todas las disciplinas diseñen, orienten y evalúen tareas de escritura de forma efectiva, de manera que los estudiantes aprendan los contenidos de los cursos al tiempo que aprenden a comunicarse mediante las convenciones propias de su área de conocimiento. El texto está organizado en tres capítulos: en el primero se sustenta la necesidad de orientar la escritura a través del currículo en la universidad; en el segundo se presentan los principios básicos del diseño de tareas de escritura y sus formas de evaluación, enfatizando en dos herramientas didácticas: la guía escrita y la rúbrica; y en el tercero se explican las características de diez asignaciones de escritura que se usan con frecuencia en el contexto universitario. Aunque los tres capítulos están estrechamente relacionados, los lectores pueden consultar apartados puntuales de acuerdo con las necesidades de sus asignaturas. Además, al final de cada capítulo se presenta una infografía que sintetiza los temas principales. Si bien existen numerosos manuales dedicados a la escritura, la mayoría orientados a apoyar el quehacer del escritor, pocos se centran en fortalecer los acompañamientos que ofrecen los docentes para que sus estudiantes desarrollen las competencias comunicativas requeridas en el contexto académico. Esperamos, pues, que este texto ayude a los profesores a reflexionar sobre el papel de la escritura en la universidad y proporcione herramientas útiles para diseñar y evaluar tareas efectivas en sus cursos. No obstante, la diversidad de prácticas discursivas en las disciplinas, este instrumento apoya la inclusión de la escritura a través del currículo en las instituciones de educación superior

Emerging Methods to Objectively Assess Pruritus in Atopic Dermatitis.

INTRODUCTION:Atopic dermatitis (AD) is an inflammatory skin disease with a chronic, relapsing course. Clinical features of AD vary by age, duration, and severity but can include papules, vesicles, erythema, exudate, xerosis, scaling, and lichenification. However, the most defining and universal symptom of AD is pruritus. Pruritus or itch, defined as an unpleasant urge to scratch, is problematic for many reasons, particularly its negative impact on quality of life. Despite the profoundly negative impact of pruritus on patients with AD, clinicians and researchers lack standardized and validated methods to objectively measure pruritus. The purpose of this review is to discuss emerging methods to assess pruritus in AD by describing objective patient-centered tools developed or enhanced over the last decade that can be utilized by clinicians and researchers alike. METHODS:This review is based on a literature search in Medline, Embase, and Web of Science databases. The search was performed in February 2019. The keywords were used "pruritus," "itch," "atopic dermatitis," "eczema," "measurements," "tools," "instruments," "accelerometer," "wrist actigraphy," "smartwatch," "transducer," "vibration," "brain mapping," "magnetic resonance imaging," and "positron emission tomography." Only articles written in English were included, and no restrictions were set on study type. To focus on emerging methods, prioritization was given to results from the last decade (2009-2019). RESULTS:The search yielded 49 results in PubMed, 134 results in Embase, and 85 results in Web of Science. Each result was independently reviewed in a standardized manner by two of the authors (M.S., K.L.), and disagreements between reviewers were resolved by consensus. Relevant findings were categorized into the following sections: video surveillance, acoustic surveillance, wrist actigraphy, smart devices, vibration transducers, and neurological imaging. Examples are provided along with descriptions of how each technology works, instances of use in research or clinical practice, and as applicable, reports of validation studies and correlation with other methods. CONCLUSION:The variety of new and improved methods to evaluate pruritus in AD is welcomed by clinicians, researchers, and patients alike. Future directions include next-generation smart devices as well as exploring new territories, such as identifying biomarkers that correlate to itch and machine-learning programs to identify itch processing in the brain. As these efforts continue, it will be essential to remain patient-centered by developing techniques that minimize discomfort, respect privacy, and provide accurate data that can be used to better manage itch in AD

Kinematic viscosity of therapeutic pulmonary surfactants with added polymers

AbstractThe addition of various polymers to pulmonary surfactants improves surface activity in experiments both in vitro and in vivo. Although the viscosity of surfactants has been investigated, the viscosity of surfactant polymer mixtures has not. In this study, we have measured the viscosities of Survanta and Infasurf with and without the addition of polyethylene glycol, dextran or hyaluronan. The measurements were carried out over a range of surfactant concentrations using two concentrations of polymers at two temperatures. Our results indicate that at lower surfactant concentrations, the addition of any polymers increased the viscosity. However, the addition of polyethylene glycol and dextran to surfactants at clinically used concentrations can substantially lower viscosity. Addition of hyaluronan at clinical surfactant concentrations slightly increased Infasurf viscosity and produced little change in Survanta viscosity. Effects of polymers on viscosity correlate with changes in size and distribution of surfactant aggregates and the apparent free volume of liquid as estimated by light microscopy. Aggregation of surfactant vesicles caused by polymers may therefore not only improve surface activity as previously shown, but may also affect viscosity in ways that could improve surfactant distribution in vivo

Prácticas de literacidad digital de estudiantes universitarios: contrastes entre contextos vernáculos y académicos

Este artículo pretende contrastar las prácticas de literacidad digital de estudiantes universitarios de primer año en ámbitos vernáculos y académicos. Se sitúa desde enfoques socioculturales que conciben al lenguaje como un proceso construido y mediado socialmente. Se planteó un diseño etnográfico y se llevaron a cabo estudios de caso con seis jóvenes colombianos con diferentes perfiles de participación en línea. La información se recolectó mediante tecnobiografías y tecnodiarios, entrevistas en profundidad, observación participante y revisión documental multimodal. Para contrastar las prácticas, se abordaron cuatro categorías: géneros discursivos, multimodalidad, interacción e identidad. Se encontró una diversidad de prácticas de los participantes, quienes configuran sus usos de acuerdo con sus concepciones sobre la escritura, sus intereses y trayectorias. Los jóvenes tienen, principalmente, prácticas de recepción de contenidos textuales y audiovisuales e interacción en línea, pero muestran un alto compromiso y estructuración de sus actividades cuando se involucran en dinámicas de creación y participación. Se evidencian algunas desconexiones entre los ámbitos, que pueden deberse a las concepciones sobre lo vernáculo como menos relevante, pero más entretenido, y a la percepción de lo académico como estrictamente normativo. Conocer las prácticas de los estudiantes dentro y fuera del contexto académico puede aportar tanto a una mejor comprensión de sus formas de literacidad digital como a la consolidación de procesos educativos flexibles que permitan integrar los desarrollos construidos por los jóvenes en distintos ámbitos

Iscrizioni di origine romana del Museo di Preistoria di Valencia

This essay considers a little group of inscriptions which are part of an archaeological collection, formed in Rome and now preserved in the Prehistoric Museum of Valencia. Ten of the sixteen latin inscriptions here considered are pagan, five Christian and one post-classical; for every piece there¿s a short description and a picture, an interpretative transcription and a commentary. Most of texts have a funerary character, except for one, which is probably honorary, and the post-classical text which contains an exorcism against the devil

A prática pedagógica como obra de arte: aproximações à estética do professor‐artista

ResumoA partir de uma análise teórico‐conceitual da obra de Hans‐Georg Gadamer, este estudo proporciona um diálogo entre a arte, a educação e a educação física. Na procura por abrir um caminho opcional ao dominante, oferecido pela racionalidade técnico‐instrumental, discute a ideia do professor‐artista. Apresenta as reflexões sobre a obra de arte nos textos do filósofo alemão, situa‐as nos três grandes momentos da estrutura de uma prática pedagógica: planejamento, execução e avaliação. As considerações finais anunciam algumas limitações da proposta apresentada.AbstractThis study provides a dialogue between art, education and physical education from a theoretical and conceptual analysis of Hans‐Georg Gadamer's work. Toward discussing the possibility of a teacher‐artist, it searches an alternative way to the “dominant” one offered by technical‐instrumental rationality to discuss. The analysis of the work of art in the German Philosopher's texts is presented placing them in the three most important moments of the structure of a pedagogical practice: planning, implementation and evaluation. Some limitations of the proposal are announced in the final considerations
