Towards an integration of the theory of planned behaviour and cognitive behavioural strategies: an example from a school-based injury prevention programme

Adolescent risk-taking behaviour has potentially serious injury consequences and school-based behaviour change programmes provide potential for reducing such harm. A well-designed programme is likely to be theory-based and ecologically valid; however, it is rare that the operationalisation process of theories is described. The aim of this paper is to outline how the theory of planned behaviour and cognitive behavioural therapy informed intervention design in a school setting. Teacher interviews provided insights into strategies that might be implemented within the curriculum and provided detail used to operationalise theory constructs. Benefits and challenges in applying both theories are described with examples from an injury prevention programme, Skills for Preventing Injury in Youth.     

A theoretical framework for building online communities of practice with social networking tools

This paper proposes a theoretical framework as a foundation for building online communities of practice when a suite of social networking applications referred to as collective intelligence tools are utilized to develop a product or solutions to a problem. Drawing on recent developments in Web 2.0 tools, research on communities of practice and relevant theories of learning, and the authors' own action research experience in collaborative knowledge creation utilizing Web 2.0 tools, this paper discusses a learning community's spiraling process as it moves from a given sociocultural context through discourse, action, reflection, and reorganization toward socially mediated metacognition.

Un cadre théorique pour construire des communautés de pratique en ligne en utilisant des outils de maillage social

Cet article propose un cadre théorique sur lequel édifier des communautés de pratique en ligne lorsqu'on utilise, pour mettre au point un produit ou des solutions à un problème, une série d'applications destinées à la construction de réseaux humains et connues sous le nom d'outils d'intelligence collective. En s'appuyant sur les évolutions récentes des outils Web 2.0, sur les recherches sur les communautés d'usage et les théories de l'apprentissage pertinentes ainsi que sur l'expérience propre aux auteurs en matière de recherche action sur la création collaborative de savoir en utilisant le Web 2.0, le présent article examine le processus en spirale d'une communauté d'apprentissage qui part d'un contexte socio culturel donné et qui passe par le discours, l'action la réflexion et la réorganisation pour atteindre la métacognition reposant sur la médiation humaine.

Ein Theorierahmen für den Aufbau von “Online‐Communitives of Practice” mit Hilfe von Anwendungen für Social Networking

In diesem Beitrag wird ein theoretischer Rahmen als Grundlage für den Aufbau von Online‐Praxis‐Gemeinschaften vorgestellt, wenn eine Reihe von Social Networking Anwendungen, auf die man sich als kollektive Intelligenz‐Tools beziehen kann, benutzt wird, um ein Ergebnis oder eine Problemlösung zu entwickeln. Wenn man den neuesten Entwicklungsstand bei den Web 2.0 tools mit einbezieht, die Forschung im Kommunikationsbereich, die relevanten Lerntheorien und die eigenen Forschungen und praktischen Erfahrungen des Autors in der Benutzung von Web 2.0‐Anwendungen auf dem Gebiet der gemeinschaftlichen Wissensermittlung, belegt dieses Papier den spiralförmigen Prozess beim Bewegen von einem bestimmten soziokulturellem Kontext aus durch Diskurs, Aktion, Reflektion und Reorganisation hin zu sozial vermittelter Metaerkenntnis.

Un marco teórico para la construcción de comunidades de práctica en línea con herramientas de creación de redes sociales

Este artículo propone un marco teórico como base para la construcción de comunidades de práctica cuando se utiliza una serie de aplicaciones sociales en redes (conocidas como herramientas de inteligencia colectiva) para desarrollar un producto o solucionar tal o tal problema. Basandose en las evoluciones recientes de las herramientas Web 2.0, en las investigaciones sobre las Comunidades de Uso y las teorías del aprendizaje más pertinentes así como en la experiencia propia de la investigación/acción por parte de los autores sobre la creación colaborativa de conocimiento a través del uso de herramientas Web 2.0, este artículo examina la evolución « en espiral » de una comunidad de aprendizaje que sale de un contexto socio cultural determinado y pasando por el discurso, acción, reflexión, alcanza la metacognición basada en la mediación humana.     

Hydrostatic Weighing during Different Stages of the Menstrual Cycle

Abstract

This study compared the physiological responses (oxygen consumption and energy expenditure) of Nordic Walking to regular walking under field-testing conditions. Eleven women (M age = 27.1 years, SD = 6.4) and 11 men (M age = 33.8 years, SD = 9.0) walked 1,600 m with and without walking poles on a level, 200-m track. For women, Nordic Walking resulted in increased oxygen consumption (M = 14.9 ml·kg¹·min^?1 , SD = 3.2 vs. M = 17.9 ml·kg¹·min^?1 , SD = 3.5; p < .001), caloric expenditure (M = 4.6 kcal·min^?1 , SD = 1.2 vs. M = 5.4 kcal·min^?1 , SD = 1.2; p < .001), and heart rate (M = 113.7 bpm, SD = 12.0 vs. M = 118.7 bpm, SD = 14.8; p < .05) compared to regular walking. For men, Nordic Walking resulted in increased oxygen consumption (M = 12.8 ml·kg¹·min^?1 , SD = 1.8 vs. M = 15.5, SD = 3.4 ml·kg¹·min^?1; p < .01), caloric expenditure (M = 5.7 kcal·min^?1 , SD = 1.3 vs. M = 6.9 kcal·min^?1 , SD = 1.8; p < .001), and heart rate (M = 101.6 bpm, SD = 12.0 bpm vs. M = 109.8 bpm, SD = 14.7; p < .01) compared to regular walking. Nordic Walking, examined in the field, results in a significant increase in oxygen use and caloric expenditure compared to regular walking, without significantly increasing perceived exertion.     

Reconstructing Readability: Recent Developments and Recommendations in the Analysis of Text Difficulty

Largely due to technological advances, methods for analyzing readability have increased significantly in recent years. While past researchers designed hundreds of formulas to estimate the difficulty of texts for readers, controversy has surrounded their use for decades, with criticism stemming largely from their application in creating new texts as well as their utilization of surface-level indicators as proxies for complex cognitive processes that take place when reading a text. This review focuses on examining developments in the field of readability during the past two decades with the goal of informing both current and future research and providing recommendations for present use. The fields of education, linguistics, cognitive science, psychology, discourse processing, and computer science have all made recent strides in developing new methods for predicting the difficulty of texts for various populations. However, there is a need for further development of these methods if they are to become widely available.     

Health sciences librarians' awareness and assessment of the Medical Library Association Code of Ethics for Health Sciences Librarianship: the results of a membership survey

Objective:

The Medical Library Association (MLA) Board of Directors and president charged an Ethical Awareness Task Force and recommended a survey to determine MLA members'' awareness of and opinions about the current Code of Ethics for Health Sciences Librarianship.

Methods:

The task force and MLA staff crafted a survey to determine: (1) awareness of the MLA code and its provisions, (2) use of the MLA code to resolve professional ethical issues, (3) consultation of other ethical codes or guides, (4) views regarding the relative importance of the eleven MLA code statements, (5) challenges experienced in following any MLA code provisions, and (6) ethical problems not clearly addressed by the code.

Results:

Over 500 members responded (similar to previous MLA surveys), and while most were aware of the code, over 30% could not remember when they had last read or thought about it, and nearly half had also referred to other codes or guidelines. The large majority thought that: (1) all code statements were equally important, (2) none were particularly difficult or challenging to follow, and (3) the code covered every ethical challenge encountered in their professional work.

Implications:

Comments provided by respondents who disagreed with the majority views suggest that the MLA code could usefully include a supplementary guide with practical advice on how to reason through a number of ethically challenging situations that are typically encountered by health sciences librarians.     

Immigrant families’ use of early childcare: Predictors of care type

Early care and education (ECE) settings are important developmental contexts for young children, with nearly half of all U.S. children experiencing non-parental care during infancy and toddlerhood. However, there is little research examining patterns and predictors of ECE selection among immigrant families even though children of immigrants represent the fastest growing population in the U.S. Using data from the Early Childhood Longitudinal Study, Birth Cohort (N ≈ 10,700), including a diverse group of children with immigrant parents (N ≈ 2950), this study aims to fill gaps in the literature by examining predictors of the type of ECE (parent, relative, home-based, or center-based) children experience during infancy and toddlerhood (children aged 7–38 months). It examines how immigrant, family, child, and contextual characteristics predict ECE selection within immigrant families and whether these correlates of ECE selection differ across native and immigrant families. Results show distinct patterns of infant and toddler ECE related to immigrant status, particularly when it came to socioeconomic advantage predicting increased relative care for children of immigrants but not native families. Furthermore, several immigrant-specific characteristics, including region of origin, English proficiency, and availability of non-English ECE options, were associated with immigrant families’ ECE choices for their infants and toddlers.     

‘Microsoft bought Minecraft … who knows what’s going to happen?!’: a sociocultural analysis of 8–9-year-olds’ understanding of commercial online gaming industries

This study investigates children’s media literacy with a specific focus on socially situatedness of children’s understanding of online gaming industries and related marketing. This article analyzes interviews with 8–9-year-olds and their parents in homes in the U.S.A. Rather than concentrating on developmental factors, the article uses a sociocultural approach to analyze various aspects of children’s gaming culture in domestic settings that relate to their understanding of gaming industries. The article considers implications for how children as consumers are understood by key stakeholders, including researchers and educators.
