Use of the one-minute preceptor as a teaching tool in the gross anatomy laboratory

The one-minute preceptor (OMP) is a time-efficient technique used for teaching in busy clinical settings. It consists of five microskills: (1) get a commitment from the student, (2) probe for supporting evidence, (3) reinforce what was done right, (4) correct errors and fill in omissions, and (5) teach a general rule. It can also be used to address structure-identification questions in gross anatomy laboratory small-group settings. The OMP is an active learner-centered teaching approach that prepares students for a style of learning that they need to master in clinical settings, provides novice anatomy teachers with an efficient and effective teaching strategy, and moves anatomy learning beyond mere name tagging to active knowledge construction.

Convergent validity of a novel method for quantifying rowing training loads

Elite rowers complete rowing-specific and non-specific training, incorporating continuous and interval-like efforts spanning the intensity spectrum. However, established training load measures are unsuitable for use in some modes and intensities. Consequently, a new measure known as the T2minute method was created. The method quantifies load as the time spent in a range of training zones (time-in-zone), multiplied by intensity- and mode-specific weighting factors that scale the relative stress of different intensities and modes to the demands of on-water rowing. The purpose of this study was to examine the convergent validity of the T2minute method with Banister’s training impulse (TRIMP), Lucia’s TRIMP and Session-RPE when quantifying elite rowing training. Fourteen elite rowers (12 males, 2 females) were monitored during four weeks of routine training. Unadjusted T2minute loads (using coaches’ estimates of time-in-zone) demonstrated moderate-to-strong correlations with Banister’s TRIMP, Lucia’s TRIMP and Session-RPE (rho: 0.58, 0.55 and 0.42, respectively). Adjusting T2minute loads by using actual time-in-zone data resulted in stronger correlations between the T2minute method and Banister’s TRIMP and Lucia’s TRIMP (rho: 0.85 and 0.81, respectively). The T2minute method is an appropriate in-field measure of elite rowing training loads, particularly when actual time-in-zone values are used to quantify load.

大学生心肺功能监测方法的研究

以足球选项班的大学生作为研究对象,运用作者设计的12 min足球运球绕杆射门的距离,作为监测大学心肺功能的指标,并以研究对象12 min跑的成绩作为效标,采用积差相关法进行有效性估价,研究结果表明两指标之间相关程度密切,能有效地监测大学生的心肺功能.调查表明采用12 min足球运球绕杆射门作为肺功能的监测指标,比采用3 000 m跑与12 min跑更易于被大学生接受.     

浅析内部交易存货的抵销原理

企业集团内企业之间的商品购销活动实际上相当于一个企业内部物资调拨活动,既不会实现利润,也不会增加商品的价值。在编制合并会计报表时,应当将存货价值中包含的未实现内部销售利润予以抵销。因此,未实现内部销售利润是进行存货内部交易抵销处理的根本动因。     

The respiratory time and flow profile at volitional exercise termination

Abstract

In this study, we examine the effect of exercise on the time and flow characteristics of the respiratory cycle profile at the point of volitional exercise termination. Eight males (mean age 29 years, s = 10; body mass 74 kg, s = 7; height 1.75 m, s = 0.04) undertook a cycle test to volitional exhaustion on a cycle ergometer, which allowed peak oxygen uptake ([Vdot]O_2peak) to be measured (mean 51 ml · kg^?1 · min^?1, s = 7). At a later date, two sub-maximal tests to volitional exhaustion were completed in a random order at 76% (s = 6) and 86%[Vdot]O_2peak (s = 7). As expected, the magnitude of the respiratory flow and time characteristics varied with the three exercise intensities, as did the point of exercise termination and terminal ventilation rates, which varied from 7 to 27 min and 112 to 132 litres · min^?1 respectively. More importantly, however, at exercise termination some of the characteristics were similar, particularly the breathing frequency (at termination 49 breaths · min^?1), the ratio between inspiration and total breath time (0.5), and the later occurrence of peak inspiratory flow (0.24 – 0.48 s). The coincident unity of these time and flow profile characteristics at exercise termination illustrates how the integration of timing and flow during breathing influence exercise capacity in non-elite athletes.     

Keyboarding Aids

Abstract

Elementary schools across the United States are striving to find the most effective method of teaching keyboarding to their students. A number of schools make use of sensor-key capson the Dand the Kkeys. These caps have eight elevated dots forming a circle in the center of the cap. Educators would benefit from knowing if, indeed, these key caps make a significant difference in students' abilities to keyboard with increased speed and accuracy when compared to standard keys. This study was conducted on two groups of third-, fourth-, and fifth-grade students (N= 95) who completed a keyboarding unit. One group used the sensor-key caps and the other group did not. Results provided no evidence that the use of sensor-key caps improved keyboarding speed or accuracy over standard keys without the key caps.
