Nanotechnology in the food industry I: applications

Nanotechnology is a multidisciplinary science that is having a boom today, providing new products with attractive physicochemical properties for many applications. In agri/feed/food sector, nanotechnology offers great opportunities for obtaining products and innovative applications for agriculture and livestock, water treatment and the production, processing, storage and packaging of food. To this end, a wide variety of nanomaterials, ranging from metals and inorganic metal oxides to organic nanomaterials carrying bioactive ingredients are applied. This review shows an overview of current and future applications of nanotechnology in the food industry. Food additives and materials in contact with food are now the main applications, while it is expected that in the future are in the field of nano-encapsulated and nanocomposites in applications as novel foods, additives, biocides, pesticides and materials food contact.

Asumiendo las consecuencias negativas de la adicción al juego

La adicción al juego no sólo se caracteriza por la pérdida de control ante el juego, sino que esta conducta tiende a generar problemas en los diferentes ámbitos de la vida del ludópata. Por ello, este aspecto se recoge en el Manual diagnóstico y estadístico de los trastornos mentales-5 (DSM-V) como uno de los criterios para realizar su valoración diagnóstica. Objetivo: describir y analizar los diferentes elementos que conforman la compleja problemática aparejada a esta adicción y que pueden terminar en situaciones de exclusión social. Método: Se opta por una metodología cualitativa que se ajusta mejor a los intereses del estudio. Como técnica se ha seleccionado la historia de vida, instrumento de evaluación que permite conocer la verdadera magnitud del problema desde el punto de vista de los afectados. Resultados. De manera general, se ha descubierto que ser ludópata tiene muchos más consecuentes que el problema económico evidente. No debemos despreciar las implicaciones de esta conducta a otros niveles: familiar, laboral, legal y social, que pueden considerarse, a medio plazo, como factores mucho más execrables que el del mero gasto económico. Conclusión. Es fácil avistar que los graves problemas que acarrea la adicción al juego son capaces de desmembrar el proyecto vital del ludópata y el de su familia. Todo vale, aunque para ello tenga que jugarse su puesto de trabajo, su casa, su familia, sus amistades, su estatus social y su propia dignidad.

Los números cuentan. Sub-representación de la obra artística de mujeres creadoras en museos y centros de arte contemporáneos

Este artículo cuantifica la presencia de obra artística de mujeres artistas en 21 museos y centros de arte contemporáneo españoles. Los resultados constatan una nítida sub-representación de la obra exhibida, por debajo del 20 por ciento. ¿Por qué sucede esto?, ¿diferencial potencial artístico de mujeres y hombres?, ¿superioridad masculina?, ¿discriminación? o ¿un sistema de arte con sesgo androcéntrico? En estas páginas se discute sobre la presencia de varios factores para explicar la brecha de género y se reclama, de las administraciones públicas y las instituciones de gestión cultural, el cumplimiento de la Ley para la Igualdad para garantizar la paridad.

Terapia de aceptación y compromiso en un caso de tras¬torno mixto de ansiedad y depresión en una paciente con cáncer

This paper introduces the case of a woman with breast cancer who had developed a mixed depressive-anxiety disorder with avoidance behaviors. The patient presented depressive symptoms like listlessness, insomnia, weeping, food disorders and hopelessness though. Also, she exhibited physiological arousal and restlessness feelings. Additionally, the patient had an avoidance patron behavior in relation with all stimulus she believed could hurt her. Based on the Acceptance and Commitment Therapy (ACT) the intervention planted the following objectives: the patient will learn to accept her illness and the emotional distress that she was experiencing, also, the patient will recover the other areas of her life that she had abandoned. The treatment was developed in 14 sessions. The therapist used these techniques: creative hopelessness, disabling verbal functions, values clarification and loss of control over private events. In the results, it was observed a positive change in the behavior of the patient as well as a decrease in emotional distress that was his reason for initial consultation

Concept maps as a tool to analyze the ideas of teacher training students regarding what to teach on human nutrition in Primary Education

Concept maps are a technique used to obtain a visual representation of a person's ideas about a concept or a set of related concepts. Specifically, in this paper, through a qualitative methodology, we analyze the concept maps proposed by 52 groups of teacher training students in order to find out the characteristics of the maps and the degree of adequacy of the contents with regard to the teaching of human nutrition in the 3rd cycle of primary education. The participants were enrolled in the Teacher Training Degree majoring in Primary Education, and the data collection was carried out through a training activity under the theme of what to teach about Science in Primary School? The results show that the maps are a useful tool for working in teacher education as they allow organizing, synthesizing, and communicating what students know. Moreover, through this work, it has been possible to see that future teachers have acceptable skills for representing the concepts/ideas in a concept map, although the level of adequacy of concepts/ideas about human nutrition and its relations is usually medium or low. These results are a wake-up call for teacher training, both initial and ongoing, because they shows the inability to change priorities as far as the selection of content is concerned.

Correlation between anxiety and academic self-concept in interpreter trainees

This paper focuses on two basic issues: the anxiety-generating nature of the interpreting task and the relevance of interpreter trainees’ academic self-concept. The first has already been acknowledged, although not extensively researched, in several papers, and the second has only been mentioned briefly in interpreting literature. This study seeks to examine the relationship between the anxiety and academic self-concept constructs among interpreter trainees. An adapted version of the Foreign Language Anxiety Scale (Horwitz et al., 1986), the Academic Autoconcept Scale (Schmidt, Messoulam & Molina, 2008) and a background information questionnaire were used to collect data. Students’ t-Test analysis results indicated that female students reported experiencing significantly higher levels of anxiety than male students. No significant gender difference in self-concept levels was found. Correlation analysis results suggested, on the one hand, that younger would-be interpreters suffered from higher anxiety levels and students with higher marks tended to have lower anxiety levels; and, on the other hand, that younger students had lower self-concept levels and higher-ability students held higher self-concept levels. In addition, the results revealed that students with higher anxiety levels tended to have lower self-concept levels. Based on these findings, recommendations for interpreting pedagogy are discussed.
