Students’ writing problems are a global educational concern and is in need of particular attention. This study aims to examine the impact of providing extra writing opportunities (i.e., writing journals) on the quality of writing compositions. A longitudinal cluster-randomized controlled design using a multilevel modeling analysis with 182 fourth grade students was conducted. We examined whether students’ writing quality differed when writing journals on a weekly basis for 12 weeks, compared with a control group. Three covariates were analyzed, namely: (i) the students’ attitudes towards writing; (ii) their self-efficacy in writing; (iii) and their use of self-regulation (SRL) strategies while writing. Findings have shown that students who wrote week-journals significantly improved the writing quality of their compositions and reported a higher use of SRL strategies in writing. Nevertheless, self-efficacy and attitude towards writing were found to not be related to the quality of the compositions. Moreover, data indicated that the writing quality of compositions improved along with the writing quality of the week-journals. Findings suggest the use of week-journals in class to promote writing.  相似文献

This article addresses the trajectory of Archival Science in Brazil, its extracurricular characteristics and its particular relationship with Information Science within academics, its institutional associations, and some considerations regarding current training for archivists in Brazil. The methodological procedures used included analyzing documents from the National Archive Fonds of Brazil, reviewing archive literature, and interviewing people involved in consolidating Archival Science. This study concludes that Archival Science research is taking place in graduate programs throughout public Brazilian universities and points out that people working with archives now have more advanced training, such as undergraduate degrees in Archival Science or other. This study also focuses on archives as information units, while presenting and reflecting on the demands of training archivists who are faced with the challenges of the working world and the era of information and knowledge—challenges that go beyond merely technical procedures and encompass dynamic planning and orientation activities.  相似文献

论康德的道德自由与德性论   总被引:1,自引:0,他引:1  
理性与自由是康德伦理学的重要概念,如若把康德的“理性”概念分为理论理性和实践理性,那么他的“自由”概念同样也可分为理性的自由和道德的自由。理论理性和理性的自由是属于思辨哲学研究的范畴,实践理性和道德的自由是属于伦理学研究的范畴。在康德看来,道德自由是人的道德活动之原因,德性是人的道德活动之结果。因此,在康德伦理学中道德自由与德性之间有着内在的逻辑联系,不仅如此,这种道德自由与德性之内在的逻辑联系恰恰体现着康德理性主义伦理思想的精神内涵。  相似文献

The production of knowledge was subjected to quantitative analysis in the second half of the twentieth century, following Arrow (1962). The determinants of knowledge and the externalities present in the innovation process were discussed with immediate policy influence. In particular, the presence and strength of the spillover of the pool of past knowledge has encouraged high subsidization of R&D in the most developed countries. We survey the empirical literature on the spillover effect in the production of knowledge and implement a meta-analytic regression. We discover that the average spillover effect is less than but close to one and is highly significant. We also find that the spillover effect tends to be greater when the estimation of knowledge production accounts for foreign inputs, and it tends to be lower when the estimation includes only rich economies, regional data are used, and the pool of knowledge is not the patent stock.  相似文献

The aim of this study was to analyze the effects of resistance training (RT) performed with 1 or 3 sets per exercise on osteosarcopenic obesity (OSO) syndrome parameters in older women. Sixty-two older women (68.0 ± 4.3 years, 26.8 ± 4.4 kg/m2) participated in a 12-week RT program. Participants were randomly assigned into one of the three groups: two training groups that performed either 1 set (G1S, n = 21) or 3 sets (G3S, n = 20) 3 times weekly, or a control group (CG, n = 21). Body composition was assessed by dual X-ray absorptiometry, strength was evaluated by 1 repetition maximum testing. The G3S presented significantly higher strength changes than G1S. The changes for percentage of body fat were higher for G3S compared to G1S. There was no difference in skeletal muscle mass between G3S and G1S, however both training groups displayed greater increases in this outcome compared to CG. There was no effect for bone mineral density. The overall analysis indicated higher (< 0.05) positive changes for G3S than G1S (composed Z-score: G3S = 0.62 ± 0.40; G1S = 0.11 ± 0.48). The results suggest that a 12-week RT period is effective to improve the risk factors of OSO, and that 3 sets induce higher improvements than a single set.  相似文献

ABSTRACT

The main purpose of this study was to compare the effects of resistance training (RT) performed with different training volumes on phase angle (PhA), body water components, and muscle quality (MQ) in untrained older adult women. A second purpose was to assess the relationship between PhA and MQ. Sixty-two older adult women (68.6 ± 5.0 years, 65.2 ± 13.3 kg, 156.1 ± 6.2 cm) were randomly assigned into one of the three groups: two training groups performed either 1 set (G1S) or 3 sets (G3S), or a control group (CG). Body water components and PhA were estimated by bioelectrical impedance (BIA). MQ was determined by dividing skeletal muscle mass estimated by dual-energy absorptiometry (DXA) by total muscle strength from three exercises. After the intervention period, both training groups demonstrated improvements (< 0.05) when compared with CON for intracellular water, total body water, PhA, and MQ. These results suggest that RT can improve PhA, body water components, and MQ after 12 weeks of RT in untrained older women, regardless of training volume. Furthermore, changes in MQ were positively correlated with changes in PhA (r = 0.60, P < 0.01).  相似文献

首次全面论述了全世界黄华属(豆科)植物地理。黄华属是豆科少数几个东亚-北美间断分布属之一。对黄华属5组21种的分布进行了分析,发现本属4个频度分布中心依次是:东亚地区(8种/3组,其中特有种4种),伊朗-土兰地区(7种/3组,其中特有种3种),落基山地区(7种/2组,均为特有种)及大西洋北美地区(3种/1组,均为特有种)。基于以下事实:在东亚地区存在本属最多的组与种;在此区可以见到黄华属系统发育系列;该属最原始的组种及最进化的组种也在该区出现等,可以认为东亚地区是该属的现代分布中心及分化中心。伊朗-土兰地区(中亚东部至喜马拉雅)及落基山地区所含种、组数仅次于东亚地区,而且多倍体现象多发生于这两区,因此可认为是本属的次生分布中心及分化中心。在此二地区,物种分化较活跃且复杂,先后描述了很多新种和变种,也曾进行过较多的归并处理。最近的分子生物学证据不断揭示,在这地区曾被归并的一些分类群存在着较大不同,从而提醒分类学家对年轻区系中物种分化较活跃的类群进行分类处理时,无论是建新分类群还是对某些类群进行归并,应持谨慎态度。作者根据黄华属植物的现代地理分布、形态演化趋势、现有的化石及地质历史资料,推测黄华属植物在中新世之前早已形成,并且在晚第三纪欧亚大陆与北美大陆失去陆地连接之前在两大陆已经存在,很可能是于早第三纪或晚白垩纪在劳亚古陆上起源于一个含羽扇豆生物碱的古槐成员。两大陆分离后,在不同的成种因子的影响下,形成了各自的演化格局:在亚洲,晚第三纪的喜马拉雅造山运动、古地中海消失及第四纪冰川作用引起的旱化、寒化,促进了该属植物的强烈分化;而在北美,第四纪的冰川作用及局部的山体隆起,可能是促进该属植物演化的主要动力。根据黄华属植物的系统演化趋势及原始类群的分布式样分析,东亚地区的中国-日本亚区可能是本属植物的原始类型中心。  相似文献
