Analysis of movement patterns by elite male players of beach volleyball

The aim of this study was to analyse and compare movement pattems and direction of locomotion in professional men's beach volleyball. A quantitative analysis of beach volleyball play was carried out for 10 players in the European Beach Volleyball Championship 2005. Video recordings were made of the 1,997 movements in 4 matches. Analysis showed that male players used more offensive than defensive movement patterns. Defensive movement patterns were more blocks and defense than receptions. Offensive movement patterns were more attack and placements than attack preparation moves. Advance was the direction of locomotion most used. Identifying and understanding such movement patterns are vital to defining specific, effective training strategies for men's beach volleyball players.     

试论三星堆神仙体系

具有浓厚神话意味和巫史氛围的三星堆文化,原始宗教的政治形式几乎是其唯一的意识形态。在三星堆考古遗址中发现的神坛、神殿,是迄今为止我国考古发现中最具象征意义的宗教祭祀物品,100多件青铜像(面具),是一个宗教的神像系统。本文分析了其中的天神、山神、“绝地天通”的超凡神灵,特别是鸟形器和太阳轮器所表现出的日神系统,它们代表的神圣世界将灵魂、自然、天命三者贯通,是来源于远古自然观念的自然主义神灵观,带有母系氏族社会特征;通过与神话的对比研究,论述三星堆以“祭神玉璋”和神树、神坛为代表的“神址”,达到了天、地、人三界划分,是战国前原始宗教空间思维的完整再现;而作为“神圣显现”的“神迹”,则来源于神话思维的宇宙生成观。     

Type of items and the magnitude of gender differences on the Mental Rotations Test.

The present study considered the structure of the drawings used in the Mental Rotations Test (MRT) to examine whether distractors that are either a mirror image or structurally different from the target as well as response alternatives with occluded and nonoccluded parts affect the magnitude of gender differences on this test. One hundred and three women and 100 men undergraduate students were given unlimited time to complete the MRT. A gender by occlusion interaction on correct responses showed that gender differences were larger for occluded than for nonoccluded items. Examination of performance as a function of item placement in the test suggested that it is unlikely that the results could be accounted for by differential practice effects in women and men. Implications of these results for explanations of gender differences on the MRT and for the training of spatial abilities are discussed.     

也谈谢林早期思想中的“Potenz”概念

Potenz概念是谢林哲学的一个重要概念,无论是在其早期、还是在中后期的思想中。谢林对于它的使用并不是单一的,而是有两层内涵,一是“幂次”、一是“潜能”。这两种用法是有着明显区别的,各自具有不同的论述背景。而在谢林早期思想的论述背景中,谢林主要是在“幂次”这一内涵上来使用Potenz的。     

3～6岁儿童图画讲述能力的发展特点

以图画讲述作为实验任务,对儿童讲述能力的发展进行探讨。研究对象为3~6岁儿童,按年龄分为3组,共120人。研究结果表明:儿童图画讲述经历了由零散罗列、把握主要关系到围绕画面主要内容和事件进行整体讲述的发展过程。4~5岁是儿童图画讲述发展过程中的重要转折时期。画面形象的特点与图画意义的隐含性和深刻性均对儿童图画讲述有影响。     

Storywork in STEM-Art: Making,Materiality and Robotics within Everyday Acts of Indigenous Presence and Resurgence

Abstract

This article presents findings from TechTales, a participatory design research (PDR) project where learning scientists, public library staff members, informal science educators, and staff members from Native-American-serving organizations collaborated to design a family-based robotics workshop that was grounded in storytelling. We approach this by engaging Indigenous ways of knowing and being from a sociocultural learning theory perspective. Through analyzing families-in-interaction as they constructed dioramas with robotics that told their family stories, we explore how cultivating consequential learning environments in STEM is intimately intertwined with historicity, knowledge systems, and the agentic positioning of learners to design new technologies. We find that using storywork as the design focus of building dioramas created learning environments where computer programing and robotics became dynamic tools toward family-making, collaboration, and the active presencing of Indigenous knowledge systems and cultural practices. Living and interrelating with story and its knowledge systems through making were enactments of Indigenous resurgence in everyday ways. From a structure of social practices perspective, this opens up learning spaces for engagement in STEM-Art practices and in relation to other social practices of consequence, such as cultural flourishing and affiliation, collaboration and family-making, and societal repositioning.     

The Antecedent Impact of Culture and Economic Growth on Nations` Creativity and Innovation Capability

Even though the literature has widely examined culture’s effect on nations’ creativity and innovation level, it has done little to address the system theory’s perspective. However, as proponents of the system theory have argued, nations’ creativity and innovation is the cumulative effort of the various stakeholders who operate as a system, so any assessment of a nation’s creativity and innovation must consider these stakeholders’ role. This study examines the overlooked effect of culture on the broader system aspect of eighty nations’ creativity and innovationto ensure representation by both developed and developing countries. Structural equation modeling using partial least squares software is applied to analyze the data. The study found out that nations with individualist and low power distance cultural values have the highest creativity and innovation, and that a nation’s economic growth level moderates the impact of the individualist cultural value. Policymakers who seek to develop a strategy that promotes creativity and innovation at the national level benefit from these findings. Future research directions are suggested.     

Cognitive adjustment and psychological capital influences on expatriate workers’ job performance: An Ethiopian study

This study examined the relationship between cognitive adjustment and expatriates’ performance in the foreign host-country, and the moderating role of psychological capital in this relationship. The expatriates (N?=?1 229; female?=?32%; mean international tenure?=?2.99, SD?=?4.44) completed measures of cognitive adjustments (work and non-work related), psychological capital, job-performance, and organisational culture. Results from the data analysis, using the product least square method, indicate expatriates’ cognitive adjustments (work and non-work related) and psychological capital to singularly predict job performance. Psychological capital partly moderated the relationship between cognitive adjustment (work related) and expatriates’ performance.     

Too powerless to speak up: Effects of social rejection on sense of power and employee voice

Enabling and amplifying the voice of employees creates opportunities for organizational improvement. Prior research has shown that employees' sense of power has impact on their voice behavior. As such, when would employees feel too powerless to speak up in the workplace? The current study investigates the indirect effect of social rejection (via sense of power) on employee voice. We use conservation of resources theory to explain this relationship. Experimental data from two studies demonstrate that participants reminded of social rejection (vs. acceptance) exhibit a lower sense of power. Specifically, we observe that social rejection diminishes a person's sense of power, and that social acceptance does not enhance this sense. That is, social rejection has an indirect effect on employee voice through sense of power. We discuss the theoretical and practical implications of our findings with regard to social rejection, sense of power, and workplace voice behavior.     

传统中国历史思想中的"时间"与"超时间"概念

在中国文化中,“时间”铭记刻画了人所身处之境况、时势的脉动以及历史中的个人的种种表现,绝非只是对自然事件的机械式载录而已。在传统中国历史思维之中,以永恒典律(如“道”、“理”)或不朽范型(如尧、舜、三代)为标竿,而尝试去存留、体现的实践过程,构成了中国历史上各个时代的具体内容。在中国传统文化中,生命的意义与价值在于领悟历史上存在过的典范,并将这些典范接引、召唤至人们所生存的时代,也因此中国文化中的“时间”概念寓涵了某种的“超时间”特质：中国人对过往历史的学习,其实只是掌握“超时间”的基点,其究极目的在于将典律范型落实于当代时空之中。中国人所认知的“时间”概念与人文关怀紧密相系;历史上的“时代”就是“时间”的会串、整合与界分;所谓“超时间”乃是从各时代中提炼出的典律范型;而经由人们的描摹叙述,“时间”会经由口语及交书而被转化成“历史”。抽象的“超时间”概念实取自“时间”,俯瞰着“时间”的流转,并且贯穿了整部“历史”的发展。本文先论述中国人文主义具有强烈的“天人合一”特质,表现出明显的社会政治取向,一切思想都落实到当下即是的人生与现实。人与自然、超自然的关系在传统中国仍被统纳入“人事”的范畴。本文第一节论证中国史学体现：中国历史意识中,“时间”与“超时间”有其错综复杂的关系：“时间”将确切发生的一桩桩事件织结成全幅的网络,而“超时间”是从网络中凝塑出来的中心意义。第二节论证“时间”如何汇淬成“超时间”,而第三节分析“超时间”必须以“时间”为基础始可形成,最后一节则对中国历史思维的特质作进一步的探讨。
