21世纪中国崛起之依托:雄鸡发展战略模式

"中国雄鸡发展战略模式"是从象形的角度假设命名的,即中国像一只昂首挺立于东方的雄鸡,并伸展着两个巨大的翅膀:"北翼"是上海合作组织,"南翼"是中国———东盟自由贸易区。实际上它是对中国在21世纪以更积极、更开放的姿态走向世界,迎接挑战,把握机遇,而投身于区域经济集团化浪潮中的发展战略总和的抽象概括。这种发展战略模式是以中国的崛起为前提的,也是以中国的崛起和发展为动力的,同时也是有利于中国的崛起和发展的"双赢"模式。随着这只雄鸡不断地茁壮成长,中国才能从容不迫地发挥一个世界大国的作用。

Effects of power variation on cycle performance during simulated hilly time-trials

It has previously been shown that cyclists are unable to maintain a constant power output during cycle time-trials on hilly courses. The purpose of the present study is therefore to quantify these effects of power variation using a mathematical model of cycling performance. A hypothetical cyclist (body mass: 70?kg, bicycle mass: 10?kg) was studied using a mathematical model of cycling, which included the effects of acceleration. Performance was modelled over three hypothetical 40-km courses, comprising repeated 2.5-km sections of uphill and downhill with gradients of 1%, 3%, and 6%, respectively. Amplitude (5–15%) and distance (0.31–20.00?km) of variation were modelled over a range of mean power outputs (200–600?W) and compared to sustaining a constant power. Power variation was typically detrimental to performance; these effects were augmented as the amplitude of variation and severity of gradient increased. Varying power every 1.25?km was most detrimental to performance; at a mean power of 200?W, performance was impaired by 43.90?s (±15% variation, 6% gradient). However at the steepest gradients, the effect of power variation was relatively independent of the distance of variation. In contrast, varying power in parallel with changes in gradient improved performance by 188.89?s (±15% variation, 6% gradient) at 200?W. The present data demonstrate that during hilly time-trials, power variation that does not occur in parallel with changes in gradient is detrimental to performance, especially at steeper gradients. These adverse effects are substantially larger than those previously observed during flat, windless time-trials.     

Maximum Product,Even Less Process: Increasing Efficiencies in Archival Processing Using ArchivesSpace

As the archival profession has adapted to new challenges and adopted modern practices like More Product, Less Process, the University of Minnesota has embraced these changes. Even so, implementing new practices can take time and effort. With the adoption of ArchivesSpace in 2016, the University found itself being fast-tracked to even more efficient methods for establishing physical and intellectual control over collections. This article will examine the case studies of two large collections that were in the midst of being processed when ArchivesSpace was implemented at the University of Minnesota. How did the switch to ArchivesSpace impact the processing of these collections, and how will these experiences impact the future of archival processing at the University?     

程序民主的完美典范:雅典陪审法庭

本文借助文本资料和考古资料,重现了古代雅典陪审法庭的运作过程。在此基础上,作者提出,雅典人以平等、公平、公正为目标,通过把陪审员名额分配上的硬性规定与分配法庭时的弹性机率、程序的公开性与投票的秘密性相结合,并配以对程序协助者的监督,从而创造了古典社会中程序民主的典范。     

面向在校大学生培养党政后备人才模式纵论

在实施人才强国战略中,建立党政后备人才培养体系是加强党的执政能力建设,从更高的战略层面推进人才队伍建设可持续发展的重要举措。面对日益激烈的人才竞争,大学生成为党政后备人才资源群体有其历史的合理性;面向在校大学生培养党政后备人才要立足于当代大学生的现实特点和后备人才的未来的双重视角,充分关注其特殊性,着重培养强化他们的政治思维素质、社会责任感、理论联系实际能力、健全的个性心理品质、完善和谐的人格。面向在校大学生培养党政后备人才模式,对广大经济欠发达地区具有普适性。

应用管理系统在局域网中的总体设计

随着计算机关系型数据库语言的丰富与完善,特别是FOXBASE最新一代的数据库管理系统软件的出现,以及各种管理系统开发工具软件的使用,使得在开发一个计算机系统时,最感困难和复杂的已不再是具体程序的编写,而是整个系统的规划。大连市委组织部开发的《大连市组织工作信息管理网络系统》即是整个系统的规划在局域网络中的总体设计的想法和思路。     

High-extensible scene graph framework based on component techniques

INTRODUCTION With the tremendous growth of the digital en- tertainment industry in the past decades, the scale of game scene is becoming more gigantic. To effectively manage and organize the massive data, game engine usually uses hierarchical scene graph. Many popular 3D modelling tools, such as Maya, 3D Studio Max, use scene graph to manage the scene content (Sowizral, 2000). 3D modelling software—Houdini directly edits scene graph to create and modify the virtual environment. Most v…
