逢源大街至荔湾湖历史街区保护与更新调查研究

无论从历史、文化,还是景观等多种层面而言,广州市逢源大街至荔湾湖历史文化街区都具有很高的保护和研究价值.此地区的保护、改造工程也借助亚运这个契机得以全面的实现.然而,在此次城市更新中,行为与制度间仍存一些矛盾冲突,导致规划目的与实施结果产生脱节的现象.通过对此历史街区保护与更新现状的调研,记录好的方法,总结经验教训,提出了对历史城区更新的一系列反思,以促进城市传统历史文化片区的可持续发展.     

论作为陶渊明重要思想资源的“齐物观”

老子"道"的存在具有"绝对性"的思想可直接引发万物一律齐平的观念,也引发了庄子更加完备的齐物观。而陶渊明疏离实际政治前提下的自我实现则是以"齐物观"为重要的思想资源和精神支撑的。     

传统文化教育在大学语文教学中的实现途径

在大学语文教学中,传统文化教育的顺利实施,需要打造高素质的教学队伍,要求教师学者化;需要选编适用教材,给学生学习传统文化搭建一个有效载体;需要创新教学模式,改革教学方法,凸显传统文化教育特色;需要积极探求新的评价体系,在指导学生论文写作方面进行有益尝试。     

合芜蚌文化创意产业集群发展机制——基于极化效应视角的分析

安徽合芜蚌地区,依赖其文化创意核心竞争优势,产生五大文化创意产业,并在极化效应持续作用下,形成文化创意产业集群。合芜蚌文化创意产业集群,虽已初具一定产业规模,但通过研究该产业集群形成机制,不难发现其发展瓶颈问题仍较为突出,因而,应从增强极化引力方面入手,突破该产业集群发展瓶颈,努力提升该产业集群发展水平。     

从认知关联的角度浅析语用失误

语言交际以认知为基础,语用失误的原因可以从认知角度进行分析。语用失误与语言使用的认知语境的假设、交际双方之间的明示和推理过程以及理想化认知模式有关。本文从认知语境、明示-推理模式以及理想化认知模式等认知语用学角度,结合关联理论,对语用失误的成因进行探讨。

Pedometer-determined physical activity and its comparison with the International Physical Activity Questionnaire in a sample of Belgian adults

Pedometer-determined physical activity (PA) levels in Belgian adults were provided and compared to PA scores reported in the International Physical Activity Questionnaire (IPAQ). The representative sample (N=1239) of the Belgian population took on average 9655 (4526) steps/day. According to pedometer indices 58.4% were insufficiently active. Steps/day differed significantly between gender (F = 5.0, p = .026), age groups (F = 3.3, p = .01), employment status (F = 6.2, p = .013), and days of monitoring (F = 7.4, p = .007). Steps/day were negatively correlated to the time spent sitting and positively to PA at work, in transport, and in leisure time (p < .001). Steps data can discriminate between PA levels reported in the IPAQ. Belgian population pedometer-determined PA levels are higher than those reported in samples of the United States; however, there is a wide distribution of ambulatory behavior     

Optimized versus corrected peak power during friction-braked cycle ergometry in males and females

The aim of this study was to compare optimization and correction procedures for the determination of peak power output during friction-loaded cycle ergometry. Ten male and 10 female sports students each performed five 10-s sprints from a stationary start on a Monark 864 basket-loaded ergometer. Resistive loads of 5.0, 6.5, 8.0, 9.5, and 11.0% body weight were administered in a counterbalanced order, with a recovery period of 10 min between sprints. Peak power was greater and occurred earlier, with less work having been done before the attainment of peak power, when the data were corrected to account for the inertial and frictional characteristics of the ergometer. Corrected peak power was independent of resistive load (P > 0.05), whereas uncorrected peak power varied as a quadratic function of load (P < 0.001). For males and females, optimized peak power (971 +/- 122 and 668 +/- 37 W) was lower (P < 0.01) than either the highest (1074 +/- 111 and 754 +/- 56 W respectively) or the mean (1007 +/- 125 and 701 +/- 45 W respectively) of the five values for corrected peak power. Optimized and mean corrected peak power were highly correlated both in males (r = 0.97, P < 0.001) and females (r = 0.96, P < 0.001). The difference between optimized and mean corrected peak power was 37 +/- 30 W in males and 33 +/- 14 W in females, of which approximately 15 W was due to the correction for frictional losses. We conclude that corrected peak power is independent of resistive load in males and females.
