    Lithium-ion batteries in a pouch form offer high energy density and safety in their designs and more recently they are offering performance at higher rates. Lithium Technologies 9Ah high-power pouch cells were studied at different rates, thermal environments, under vacuum and several different conditions of abuse including overcharge, over-discharge and external short circuit. Results of this study will be presented

    In an attempt to reveal the various types of learning environments present in 30 mathematics classrooms in five Catholic high schools, this replication study examined student (N = 602) perceptions of their classrooms using the Classroom Environment Scale. Student attitudes toward mathematics were assessed by the Estes Attitude Scale. Extending previous research conducted in public high schools, this study delineated two basic types of learning environments (teacher-centered and student-centered) in Catholic high schools. In contrast with students in public schools, students in these parochial schools reported positive attitudes toward mathematics regardless of the type of learning environment. Discussion of the findings and implications for practice, including the utility of the CES, are summarized. Résumé Cette reprise de l’étude a examiné la manière dont les élèves (N = 602) percevaient leur salle de classe à l’aide de l’échelle du milieu scolaire pour tenter de montrer les différents types d’environnement pédagogiques présents dans 30 classes de mathématiques de cinq lycées catholiques. L’attitude des élèves envers les mathématiques a été évaluée à l’aide de l’échelle d’attitude d’Estes. Dans le prolongement des recherches précédentes conduites dans des lycées publics, cette étude a défini deux types d’environnement pédagogique (centré sur le professeur et centré sur l’élève) dans les lycées catholiques. Contrairement aux élèves des établissements publics, les élèves des écoles paroissiales ont présenté des attitudes positives envers les mathématiques, quel que soit le type d’environnement pédagogique. La discussion des conclusions et des incidences sur la pratique, y compris l’utilité de l’échelle du milieu scolaire) y sont résumées. Resumen En un intento de revelar varios tipos de ambientes de aprendizaje presentes en 30 aulas de matemáticas en cinco escuelas preparatorias católicas, esta réplica de estudio examinó percepciones de estudiantes (N = 602) de sus aulas usando una escala de ambiente del aula (CES, por sus siglas en inglés). Se evaluaron las opiniones de los estudiantes hacia las matemáticas mediante el baremo Estes Attitude Scale. Al extender investigaciones previas conducidas en escuelas preparatorias públicas, este estudio delineó dos tipos básicos de ambientes de aprendizaje (centrado en el profesor y centrado en el estudiante) en escuelas preparatorias católicas. En contraste con estudiantes de las escuelas públicas, los estudiantes de las escuelas católicas mostraron opiniones positivas hacia las matemáticas, sin importar el tipo de ambiente del aprendizaje. Se resumen discusiones sobre los hallazgos, así como implicaciones para la práctica, incluyendo la utilidad de los CES

    Caring and Dominance Affect Participants' Perceptions and Behaviors During a Virtual Medical Visit

    BACKGROUND: Physician communication style affects patients' perceptions and behaviors. Two aspects of physician communication style, caring and dominance, are often related in that a high caring physician is usually not dominant and vice versa. OBJECTIVE: This research was aimed at testing the sole or joint impact of physician caring and physician dominance on participant perceptions and behavior during the medical visit. PARTICIPANTS AND DESIGN: In an experimental design, analog patients (APs) (167 university students) interacted with a computer-generated virtual physician on a computer screen. Participants were randomly assigned to 1 of 4 experimental conditions (physician communication style: high dominance and low caring, high dominance and high caring, low dominance and low caring, or low dominance and high caring). The APs' verbal and nonverbal behavior during the visit as well as their perception of the virtual physician were assessed. RESULTS: Analog patients were able to distinguish dominance and caring dimensions of the virtual physician's communication. Moreover, APs provided less medical information, spoke less, and agreed more when interacting with a high-dominant compared to a low-dominant physician. They also talked more about emotions and were quicker in taking their turn to speak when interacting with a high-caring compared to a low-caring physician. CONCLUSIONS: Dominant and caring physicians elicit different emotional and behavioral responses from APs. Physician dominance reduces patient engagement in the medical dialog and produces submissiveness, whereas physician caring increases patient emotionalit
