The present study describes a peer-tutoring program designed to utilize computerassisted instruction to help first through fourth graders who were entering a new school. Tutored girls increased their positive self-perceptions as a result of the tutoring program, whereas boys declined in positive self-perceptions, while exhibiting gains in reading scores. These findings suggest that prevention efforts need to consider the specific adaptation needs of transfer students by gender so as to insure a maximum fit between individual need and program scope. 相似文献

The effects of training on FNDC5/irisin and its association with fitness and metabolic marker improvements induced by training have been poorly investigated in humans. Thus, the present study assessed the effects of combined training (CT) on FNDC5/irisin levels, metabolic markers and fitness adaptations in obese men. Middle-age obese men (age 49.13?±?5.75, body mass index (BMI) 30.86?±?1.63) were randomly distributed in the CT group (n?=?12) and control group (CG n?=?10). The CT consisted of strength followed by aerobic training, 3 times/week, for 24 weeks. Body composition, physical fitness, plasma FNDC5/irisin, biochemical markers and metabolic scores/index were evaluated. CT maintained FNDC5/irisin levels (µg/mL) (pre: 4.15?±?0.32, post: 4.21?±?0.32; p?=?.96) and improved body composition, metabolic and physical fitness markers. In the CG, decreased FNDC5/irisin (µg/mL) (pre: 4.36?±?0.23, post: 3.57?±?0.94; p?=?.01) and reduced strength (supine exercise/kg) (pre: 71?±?14.7, post: 60.1?±?14.05; p?<?.01) were observed, along with a trend to increase HOMA-IR (pre: 2.63?±?1.11, post: 3.14?±?1.27; p?=?.07) and other indicators of metabolic deterioration. An inverse correlation was found between the change (Δ%) in levels of FNDC5/irisin and Δ% glucose, Δ% total cholesterol, Δ% triglycerides and Δ% waist circumference, in addition to a positive relation with Δ% muscle strength. In conclusion, CT maintained FNDC5/irisin levels and provided metabolic and fitness benefits. The correlation between FNDC5/irisin changes and metabolic parameters, as well as the FNDC5/irisin reduction associated with fitness and metabolic worsening in the CG, suggests a relationship between FNDC5/irisin and a healthy metabolic status in humans. 相似文献

Interprofessional education (IPE) – students of different professions learning together, from and about each other – is increasingly common in health professional degrees. Despite its explicit aims of transforming identities, practices and relationships within/across health professions, IPE remains under-theorised sociologically, with most IPE scholarship focussed on evaluating specific interventions. In particular, the significance of a shared knowledge base for shaping professional power and subjectivity in IPE has been overlooked. In this paper we begin to develop a framework for theorising IPE in allied health, by drawing parallels with a cognate area in which there has already been fruitful conceptual development: interdisciplinarity. Specifically, we offer a worked example of how the two areas may be brought into dialogue, by deploying Barry, Born and Weszkalnys’ (2008) conceptualisation of interdisciplinarity as a lens for understanding IPE. Following Barry et al. (2008) we delineate a number of ‘modes’ and ‘logics’ of knowledge-production that emerge both in IPE literature and in our own empirical study of IPE. Our empirical data are drawn from 32 semi-structured interviews with 19 allied health students participating in an IPE curriculum at one Australian university. Findings point to the emergence of interprofessional practitioner identities among students that have the potential to undermine traditional epistemological boundaries and transcend role-based distinctions in future health profession(al)s. We argue that Barry et al.’s ‘logic of ontology’ sheds light on previously unidentified processes of transformation within IPE, and offers a theoretical framework that can explain the importance of a shared pan-professional knowledge base for the reflexive individual construction of new interprofessional ontological subjects. 相似文献

The work reported in Ref. (1), carried out on n-heptane from 273·16K to the critical point (under moderate pressures), is extended to five n-alkanes, benzene, mercury and water under saturation pressures and extended to much lower temperatures.Forty calculations of various thermodynamic quantities pertaining to the liquids here studied (648 points) are presented in Tables II-IV. All parameters and physical constants involved are presented in Table V. The Standard Percentage Errors (SPE) for all the calculations and the temperature ranges are given in Table VI. The grand average SPE for the 648 points is about one-third of 1%. Only one calculation (the temperature of water from 393·16 to 563·16 K) had an error greater than 1% (18 points). 相似文献

An experimental study was made of the electrical discharge between parallel plates when the pressure between the plates had been reduced to a value slightly less than the critical pressure—i.e. to the condition when a tube begins to harden. Under these conditions the application of a transverse magnetic field will produce a discharge between the electrodes for potentials less than the normal potential required. It is believed that this is due to the lengthening of the path traversed by the ions in crossing the gap. The results obtained may be harmonized by means of the values found by Carr (Proc. Roy. Soc. 1903) who made a study of Paschen's Law in the region of critical pressure. In general it is found possible, under the conditions studied, to start a discharge and control the value of the current through a circuit of which the gap is a part by means of varying the magnetic field superposed on the gap and without altering either the impressed E.M.F. or the ohmic resistance of the circuit.This control is effected by altering the effective length of the spark gap in the circuit by means of the external magnetic field. 相似文献
