THE GERIATRIC INTERDISCIPLINARY TEAM APPROACH: CHALLENGES AND OPPORTUNITIES IN EDUCATING TRAINEES TOGETHER FROM A VARIETY OF DISCIPLINES

The special health needs of older persons and the organization of managed care systems necessitate interdisciplinary team health care. However, there is a paucity of training or familiarity with team care among most health care professionals. This article describes one nationwide initiative, funded by the John A. Hartford Foundation, in which eight sites trained health care workers from different disciplines to participate as interdisciplinary geriatric health care team members. Although the goal of the initiative was to develop trained interdisciplinary team participants, a major concern of the programs was the initial overcoming of challenges to training professionals from different disciplines together. Both benefits and challenges are identified and several training modalities and techniques to meet the challenges are discussed. These include case studies, standardized patients, cross-discipline role-playing, glossaries, and use of the DISC Personality Profile. The benefits of each of these modalities are examined, and potential pitfalls and perils to be avoided are emphasized.     

Classification of Physical Activity Cut-Points and the Estimation of Energy Expenditure During Walking Using the GT3X+ Accelerometer in Overweight and Obese Adults

This study establishes tri-axial activity count (AC) cut-points for the GT3X+ accelerometer to classify physical activity intensity in overweight and obese adults. Further, we examined the accuracy of established and novel energy expenditure (EE) prediction equations based on AC and other metrics. Part 1: Twenty overweight or obese adults completed a 30 minute incremental treadmill walking protocol. Heart rate (HR), EE, and AC were measured using the GT3X+ accelerometer. Part 2: Ten overweight and obese adults conducted a self-paced external walk during which EE, AC, and HR were measured. Established equations (Freedson et al., 1998; Sasaki et al., 2011) overestimated EE by 40% and 31%, respectively (p < .01). Novel gender-specific prediction equations provided good estimates of EE during treadmill and outdoor walking (standard error of the estimate = .91 and .65, respectively). We propose new cut-points and prediction equations to estimate EE using the GT3X+ tri-axial accelerometer in overweight and obese adults.     

Simulation,seduction, and bullshit: cooperative and destructive misleading

This paper refines a number of theoretical distinctions relevant to deceptive play, in particular the difference between merely misleading actions and types of simulation commonly considered beyond the pale, such as diving. To do so, I rely on work in the philosophy of language about conversational convention and implicature, the distinction between lying and misleading, and their relation to concepts of seduction and bullshit. The paper works through a number of possible solutions to the question of what is wrong with simulation and its difference from strategic fouling, including the argument that games and their rules operate like contracts. I conclude that the wrongness lies in the injustice of unfair advantage gained through actions that silence opposition by resort to unanswerable play.     

Pre-school Education: Parents' preferences,knowledge and expectations Enseignement Prescolaire: Preferences,connaissances et attentes des parent Educacio´n Preescolar: Preferencias,conocimiento y expectativas de los padres

Constructive partnerships between pre-school service providers and parents need to be established on the basis of a clear understanding of what parents want and expect for their children from pre-school provision. A questionnaire survey to 911 parents across Scotland, together with in-depth interviews with 91 parents in the Glasgow area, elicited information concerning preferences, beliefs, knowledge and expectations when choosing suitable provision. Results showed that parents prioritise the safety and care of their children above all else and that, beyond this, selection of type of provision (playgroup, local authority or private nursery) depends upon the relative value they attached to education, setting, convenience and meeting parents' needs. Results are consistent with the theory of planned behaviour that predicting actual choice of provision depends upon parents' knowledge, strength of desire to place their child, social support and perceived control over available options. Des partenariats constructifs entre prestataires de services préscolaires et parents doivent être établis sur la base d'une compréhension claire de ce que les parents veulent et attendent des prestations préscolaires pour leurs enfants. Les réponses à un questionnaire de 911 parents dans toute l'Ecosse, ainsi que des entretiens approfondis avec 91 parents de la région de Glasgow, ont permis de dégager des informations sur les préférences, les croyances, les connaissances et les attentes des parents choisissant une prestation. Les résultats ont montré que les parents donnent la priorité à la sécurité et à l'accueil de leurs enfants par-dessus tout, et que, après cela, la sélection du type de prestation (garderie, crèche municipale ou privée) dépend des valeurs relatives qu'ils attachent à l'éducation, au cadre, au côté pratique et à la capacité de la structure à répondre aux besoins des parents. Les résultats confirment la théorie du comportement basé sur un objectif qui prédit que le choix de prestation dépend des connaissances des parents, de la force de leur désir de placer leur enfant, du soutien social et de leur perception de leur contrôle sur les options disponibles. Las asociaciones constructivas entre los proveedores de servicio preescolar y los padres deben establecerse en base a un entendimiento claro de lo que los padres quieren y esperan de sus hijos y su provisión preescolar. Una encuesta realizada a 911 padres de Escocia, junto con unas entrevistas exhaustivas de 91 padres de la zona de Glasgow, aportó información sobre preferencias, creencias, conocimiento y expectativas cuando se escoge una provisión adecuada. Los resultados demostraron que los padres ponen en primer lugar la seguridad y cuidado de sus niños, por encima de cualquier otra cosa, y que, después, la selección del tipo de provisión (grupo de actividades, autoridades locales o guarderías privadas) dependen del valor relativo que agregan a la educación, posición, conveniencia y a satisfacer las necesidades de los padres. Los resultados son consistentes con la teoría de comportamiento planificado, que dice que pronosticar una selección actual de provisión dependen del conocimiento de los padres, intensidad de deseo de colocar a su hijo, asistencia social y control percibido sobre opciones disponibles.     

Sex-related differences on a task of volume and density

A sex-related difference, favoring boys, was found on initial performance of two samples (one British, one American) of 10- and 11-year-old children on a task of volume and density. After a period of classroom instruction that included opportunities for children to interact with appropriate materials and each other, both boys and girls performed at a higher level on the task, but the difference between them remained the same. There was no indication of a sex-related difference other than a time lag, in pattern of development of the concept. The question of why there is a sex-related difference, which persists in spite of experience and instruction, is discussed.
