Effects of Ventilation on Segmental Bioimpedance Spectroscopy Measures Using Generalizability Theory
A. Allan Turner Albert Lozano-Nieto Marcel Bouffard 《Measurement in physical education and exercise science》2013,17(2):116-129
The purpose of this study was to examine the effect of three ventilation conditions (i.e., normal, regimented, and no-ventilation) on the reproducibility of bioimpedance scores in humans for the forearm and trunk segments. One hundred able-bodied North American men and women, from 18 to 71 years of age, volunteered as participants. The experimenters used a Xitron Bio-Impedance Analyzer System model 4200 instrument with Hydra software (Xitron Technologies, San Diego, California, USA) to collect bioimpedance data on extracellular fluid and intracellular fluid scores. The experimenters analyzed the data using the generalizability theory,with persons as the facet of differentiation and time as the facet of generalization. The major findings were (a) ventilation conditions did not have a significant impact on the reproducibility of the test scores, (b) the forearm segment produced consistently higher intracellular fluid generalizability coefficients across three ventilation conditions for both gender groups when compared to the trunk segment, (c) the trunk segment produced intracellular fluid generalizability coefficients that were higher for the male group, and (d) the measurement error affected extracellular fluid scores less than segmental intracellular fluid scores. 相似文献

Après l'étude clinique de 22 cas d'intervention sociale à domicile, l'auteur rend compte des réflexions théoriques que ce type d'intervention lui a suggérées. En premier lieu, il a constaté que le comportement de mauvais traitements à enfant était lié à des problématiques aussi diverses qu'un conflit conjugal, des liens affectifs pervers, ou encore une relation à caractère psychotique: Il est donc impossible de dégager à posteriori une “ligne directive unique” dans l'aide apportée à ces familles. Ensuite, il a observé que le rôle mobilisateur de ces interventions était étroitement lié au mandat d'autorité dont le travailleur social était investi et à la possibilité qu'il détenait de demander un placement de l'enfant maltraité. Il en conclut que l'efficacité de ces moyens dépendait autant de la problématique propre à chaque famille que de l'adaptation technique que le travailleur social pouvait en faire dans sa relation avec elle. 相似文献

As a teaching method, tutorials are fundamental to university education, and are underpinned by the following goals: to accompany students; to help them establish a clear training pathway; and to promote their academic achievement. Our proposal aims to introduce psychological aspects into the Tutorial Action Plan (TAP) which, while often left unattended, are closely related to academic achievement. Our objective is to identify the relation between the academic commitment of pre-service teachers (preschool education, primary education and double degree students) at the UB and stress and coping skills, academic motivation, achievement and self-efficacy, as well as the opinions of students and tutors on the resources used during TAP and potential improvements to it. This is a transversal prospective exploratory study, applying the following questionnaires: Academic commitment (UWESS-9); Perceived Stress Scale (PSS); Self-efficacy (NGSE); Motivation (MSLQ); and two ad hoc online questionnaires. In conclusion, we hope that the results of this study will help us reformulate the TAP of said degree programmes, improving personalized attention and the quality of the student tutorial system, which is one of the standards used to assess universities. 相似文献

High-resolution magnetic resonance (MR) imaging today allows the in vivo quantification of the surface area of the cortex covering the planum temporale and permits assessment of the direction and degree of individual left-right asymmetry of this structure. This methodologic advance is promoting new studies on the biological mechanisms of anatomic and functional lateralization and on the structural accompaniments of disorders such as developmental dyslexia. It is important to stress that studies must agree on the definition and measurement of planum asymmetry, and we review our definition and its justification in the present article.Data obtained from normal subjects supported the assumption that planum (a)symmetry underlies functional lateralization. Thus, familial sinistrality predicted for symmetry of the planum in all eight left-handers studied. The pattern of planum symmetry in the normals was similar to that found in the post mortem studies of dyslexic individuals. Insofar as hand preference and developmental dyslexia are in part genetically transmitted, we suggest that planum symmetry may represent an inherited condition as well. Further-more, even though planum symmetry is part of the anatomic substrate of developmental dyslexia, it is unlikely that it represents a form of developmental anatomic pathology. 相似文献

Peer assessment is understood to be an arrangement with students assessing the quality of their fellow students’ writings and giving feedback to each other. This multiple‐case study of seven designs of peer assessment focuses on the contribution of peer assessment to the acquisition of undergraduates’ writing skills. Its aim is to arrive at an optimal design of peer assessment. Factors included in this study are: the quality of peer assessment activities, the interaction between students in oral peer feedback, students’ learning outcomes, and their evaluation of peer assessment. Most students took assessing the work of their fellow students seriously, and included the peer feedback in the revision of their work. In most conversations, students provided feedback in an evaluative manner. In others, the interaction was more exploratory. For peer assessment, we recommend a combination of written and oral peer feedback. 相似文献

This article highlights some of the obstacles facing tenure-track faculty of color in academia. Through the perspective of
Critical Race Theory (CRT) and by using a counterstories method, four faculty of color share their experiences as they explore
diversity issues through engaging in a 1-year self-study. Findings of this qualitative study provide important insights from
the perspectives of faculty of color to address ways in which to identify supports that lever barriers during the tenure process. 相似文献

New Public Management and bureaucratic models fail to acknowledge the value of peer-to-peer cooperation between citizens as a resource for public service support. Social media enable citizens to create environments for sharing information about public services in Communities of Public Service Support. The success of this model for public service support depends on the availability of communities, the level of active participation, and the information content. This paper presents an empirical study of virtual communities of expats in The Netherlands. Our analysis shows that there is a wide variety of virtual expat communities with a high level of participation and valuable content. We conclude that virtual communities play an important role in public service support since they facilitate social learning between citizens. 相似文献

The present study aims to assess comorbidity of posttraumatic stress disorder (PTSD) in anxiety and depressive disorders and to determine whether childhood trauma types and other putative independent risk factors for comorbid PTSD are unique to PTSD or shared with anxiety and depressive disorders. The sample of 2402 adults aged 18–65 included healthy controls, persons with a prior history of affective disorders, and persons with a current affective disorder. These individuals were assessed at baseline (T0) and 2 (T2) and 4 years (T4) later. At each wave, DSM-IV-TR based anxiety and depressive disorder, neuroticism, extraversion, and symptom severity were assessed. Childhood trauma was measured at T0 with an interview and at T4 with a questionnaire, and PTSD was measured with a standardized interview at T4. Prevalence of 5-year recency PTSD among anxiety and depressive disorders was 9.2%, and comorbidity, in particular with major depression, was high (84.4%). Comorbidity was associated with female gender, all types of childhood trauma, neuroticism, (low) extraversion, and symptom severity. Multivariable significant risk factors (i.e., female gender and child sexual and physical abuse) were shared among anxiety and depressive disorders. Our results support a shared vulnerability model for comorbidity of anxiety and depressive disorders with PTSD. Routine assessment of PTSD in patients with anxiety and depressive disorders seems warranted. 相似文献
