Large-scale genotyping identifies 41 new loci associated with breast cancer risk
2013
Journal article Breast cancer is the most common cancer among women. Common variants at 27 loci have been identified as associated with susceptibility to breast cancer, and these account for ~9% of the familial risk of the disease. We report here a meta-analysis of 9 genome-wide association studies, including 10,052 breast cancer cases and 12,575 controls of European ancestry, from which we selected 29,807 SNPs for further genotyping. These SNPs were genotyped in 45,290 cases and 41,880 controls of European ancestry from 41 studies in the Breast Cancer Association Consortium (BCAC). The SNPs were genotyped as part of a collaborative genotyping experiment involving four consortia (Collaborat…
Improving the Use of Simulation in Nursing Education: Protocol for a Realist Review
2020
BackgroundNursing education has evolved in line with societal needs, and simulation-based learning (SBL) is increasingly being used to bridge the gap between practice and education. Previous literature reviews have demonstrated the effectiveness of using SBL in nursing education. However, there is a need to explore how and why it works to expand the theoretical foundation of SBL.ObjectiveThis review aims to understand how, why, and in what circumstances the use of simulation affects learning as part of the bachelor’s program in nursing.MethodsA realist review will be conducted in accordance with the realist template for a systematic review. In particular, we will identify and explore the un…
Los sistemas alternativos y aumentativos de comunicación (SAAC) como instrumento para disminuir conductas desafiantes en el alumnado con TEA: estudio…
2017
Resumen Se describe una intervención, basada en el Programa de Habla Signada de Benson Schaeffer, para dotar de un Sistema Alternativo y Aumentativo de Comunicación (SAAC) a una niña de ocho años diagnosticada con trastorno del espectro autista (TEA). Se pretende que la alumna, mediante la utilización de signos, pueda expresar sus necesidades y disminuir las conductas desafiantes que propicia, ya que se estima que estas tienen una clara intención comunicativa. Se utiliza una metodología cualitativa de estudio de caso único y por objetivos. El programa se desarrolló en el aula de comunicación y lenguaje (CyL) de un centro público de educación infantil y primaria (CEIP) de la Comunidad Valenc…
Revista electrónica de investigación y evaluación educativa
2016
El Programa para la Evaluación Internacional de Alumnos (PISA) proporciona un marco en el que más de 80 países colaboran para construir métricas globales avanzadas para explorar los conocimientos, habilidades y atributos del estudiantado. El diseño de las evaluaciones plantea importantes desafíos conceptuales y técnicos, como el éxito del aprendizaje. Más allá de una base conceptual sólida, PISA necesita cumplir una serie de exigencias a veces contradictorios. Los/as administradores de escuelas, autoridades normativas y los docentes deben ser capaces de utilizar esta información de la evaluación para determinar cómo crear mejores oportunidades para el aprendizaje de los estudiantes. Las eva…
Algunas consideraciones en torno a la Evaluación del Sistema Educativo y a lo que ésta comporta
1994
In this article we considere the reasons for evaluating the educational system. The quality of education is a preoccupation of the governments, specially in time of crisis and of educational reforms and this quality needs and evaluation of all the educational system. In Spain the National Institute of Quality and Evaluation has been recently created in order to carry out this evaluation. We reflect about the subject and also about the methods and the agents of this evaluation. We ask for a democratic and cooperative evaluation.
“Congratulations, you’re on TV!”: Middle-space performances of live tweeters during the FIFA World Cup
2018
Social television has transformed the traditional role of the television viewers by providing ‘ordinary people’ access to the public stage. This article describes how public access to television affected the dialogues of Finnish tweeters on Twitter during the massive media event of the FIFA World Cup. Through the lens of digital conversation analysis, the study shows how the media publicity of tweets changed the direction of the interaction between tweeters and transformed their roles vis-à-vis the television show, making one of them into a ‘media flasher’ and the others viewers of his or her performance. The publicity was constructed as important through noticings, congratulations, and com…
The role of adolescents' temperament in their positive and negative emotions as well as in psychophysiological reactions during achievement situations
2019
Abstract This study examined the role of adolescents' (n = 190) temperament in their emotional reactions in achievement situations. Adolescents rated their temperament (i.e., surgency/extraversion, negative affectivity, effortful control) and completed achievement tasks in Grade 6. They also reported their emotions before and during challenging and non-challenging tasks. In addition, adolescents' autonomic nervous system reactions (i.e., skin conductance levels) were recorded. The results showed that high effortful control was related to higher levels of positive emotions independent of the degree of task difficulty. Low negative affectivity and high effortful control were related to lower …
Advantages of Hyaluronic Acid and Its Combination with Other Bioactive Ingredients in Cosmeceuticals
2021
This study proposes a review on hyaluronic acid (HA) known as hyaluronan or hyaluronate and its derivates and their application in cosmetic formulations. HA is a glycosaminoglycan constituted from two disaccharides (N-acetylglucosamine and D-glucuronic acid), isolated initially from the vitreous humour of the eye, and subsequently discovered in different tissues or fluids (especially in the articular cartilage and the synovial fluid). It is ubiquitous in vertebrates, including humans, and it is involved in diverse biological processes, such as cell differentiation, embryological development, inflammation, wound healing, etc. HA has many qualities that recommend it over other substances used…
Parastā kadiķa Juniperus communis L. skujas anatomiskā uzbūve
2018
Parastais kadiķis ir nozīmīga kailsēkļu suga Latvijā. Lai noteiktu kadiķa skuju anatomiskās uzbūves atšķirības dažādu laikapstākļu ietekmē, izvēlējās parametrus, kuriem noteikt izmēru atšķirības. Paraugus ievāca trīs parauglaukumos: Valmierā, Kolkā, Sakas pagastā. Katrā parauglaukumā no 30 ievāktajām skujām piecām skujām pagatavoja anatomiskos griezumus. Griezumiem veica izpēti nosakot parametru izmērus. Katrai paraugu ievākšanas vietai tuvākajai meteoroloģiskajai stacijai ievāca datus par vidējo gaisa temperatūru, nokrišņu daudzumu, gaisa mitrumu. Darbā noskaidroja, ka septiņiem no 14 skuju anatomisko uzbūvi raksturojošajiem parametriem ir statistiski būtiskas atšķirības starp parauglaukum…
Between-group competition and human cooperation.
2008
A distinctive feature of human behaviour is the widespread occurrence of cooperation among unrelated individuals. Explaining the maintenance of costly within-group cooperation is a challenge because the incentive to free ride on the efforts of other group members is expected to lead to decay of cooperation. However, the costs of cooperation can be diminished or overcome when there is competition at a higher level of organizational hierarchy. Here we show that competition between groups resolves the paradigmatic ‘public goods’ social dilemma and increases within-group cooperation and overall productivity. Further, group competition intensifies the moral emotions of anger and guilt associated…
