Age Differences in use of Strategy for Recall of Movement in a Large Scale Environment

Abstract

In order to investigate how children remember distance (route) and location (landmark) information, two experiments were conducted in a large scale environment using jogging as the means of locomotion. In Experiment 1, thirty 4-year-old and thirty 9-year-old children were randomly assigned within age to three groups which were cued prior to the jog to remember the event, location of the event or distance to the event. Results indicated that older children reproduced the location and distance better than younger children. Cueing children to remember the location resulted in more accurate estimates than the other conditions. In Experiment 2, 5-year-old, 9-year-old, and 12-year-old children (24 children of each age) were randomly divided into step counting strategy and control groups, and asked to reproduce a criterion distance jogged. Results indicated that the three strategy groups and the 12-year-old controls estimated distance with similar accuracy, but the 9- and 5-year-old controls were different, as their error was inversely related to age.     

Programming Time as a Function of Movement Constraint

Abstract

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality or gender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.

试析政党在加拿大联邦制演变中的角色表现

纵观加拿大历史,不难发现其联邦制是由集权性联邦向分权性联邦演变的,到了20世纪下半叶,甚至有人认为加拿大省所拥有的权力和地位,可能会令联合国许多主权国家感到羡慕,可见其省享有主权之大。而在省权扩大的历程中政党所扮演的角色不容忽视。     

我国优秀女子举重运动员主要专项辅助动作成绩与竞赛动作成绩相关分析

采用文献资料、专家访谈、问卷调查、数理统计等研究方法,对我国优秀女子举重运动员主要专项辅助动作成绩与竞赛动作成绩进行相关研究。结果显示:主要专项辅助动作成绩与竞赛动作成绩具高度显著性相关;高抓、高翻借力推、宽硬拉成绩与抓举成绩,下蹲翻半挺成绩与挺举成绩直接相关;高抓、高翻借力推、下蹲翻半挺成绩共同作用影响抓举成绩;下蹲翻半挺、前深蹲成绩共同作用影响挺举成绩;主要专项辅助动作成绩受爆发力和绝对力量的影响。     

20世纪90年代以来西部文学的实绩和发展动向

20世纪90年代以来，西部学仅以诗歌影响中国当代学的格局得到有力改变，西部小说家以众多优秀作品赢回公众对于学的注意力，恢复学应有的尊严。民族色彩的淡化，学地域性的强化，学的先锋性，化构成的丰富性，由单纯的视觉奇观发展为更丰富的人性体验，作为西部学背景的都市化的创生或成熟，形成西部学新的特点。西部学所拥有的转化为他种艺术形式或传播形式并形成化资本的优势和潜能，将成为西部学未来发展的一大推力。

论唐宋古文运动非以骈文为对立面

近现代以来,论者多以为唐宋"古文"是作为"骈文"对立面出现的。实际上,唐宋古文运动反对的并不是骈俪形式本身,而是文道分离的浮靡文风。韩柳欧苏不仅在理论上对骈俪相当友善,柳宗元、欧阳修、苏轼、王安石甚至还是整个骈俪文学史上的关键人物。从概念上看,"古文"与"近体文"相对,它不完全是指散行文,还部分地包含了骈文。从影响与效应的角度看,古文与骈文在唐宋以后也一直是并行发展,直到20世纪初,在现代白话文的强力打击下,才一起退出历史舞台。
