Arts sponsorship and the state of the city

This paper explores the correlation between metropolitan social and economic conditions and corporate arts support in the United States. It is hypothesized that the transition from a manufacturing sector economy to an advanced service sector economy is an important local factor for the increase in corporate arts support.By panel analysis, in eleven metropolitan areas between 1977 and 1991 changes in corporate arts support have been correlated with changes in social and economic conditions, i.e., service sector and manufacturing sector employment, service sector and manufacturing sector income, population's educational attainment, and the degree of dominance by the leading local arts supporting industry.Corporate arts support is higher in metropolitan areas where the population is better educated (=+0.60), the local service sector generates more income (=+0.37) and the local manufacturing sector generates less income (=–0.22).Corporations from the manufacturing sector are mostly indifferent towards arts support. In contrast, corporations from the service sector are supportive of the local arts but they also respond swiftly to a loss in their earnings by discontinuing their arts support.     

电子商务非技术风险的技术防范策略——基于电子商务交易主体受攻击的视角

从电子商务交易主体受攻击的角度出发,将电子商务非技术风险分为消费者面临的风险、销售商面临的风险和电子商务企业面临的风险。并从交易主体受攻击前、受攻击时和受攻击后三个时间段来构建一个电子商务非技术风险的技术防范体系。     

一类柯布-道格拉斯改型生产函数的性质

将经典的柯布-道格拉斯生产函数进行改型,得到一种生产要素间相互制约的新的生产函数,并对函数进行纯粹数学意义上的推导,得到该函数具有的一些经济性质:1)规模报酬不变;2)两要素间的技术替代率和替代弹性仅与两要素的投入比率有关,而与投入量无关;3)产品对生产要素的分配满足欧拉定理。     

高职思政课实践教学与工学结合叠加教学探索

实践教学是思政课及工学结合不可或缺的重要组成部分。积极推进思政课实践教学与专业顶岗实习的有机结合，重构与工学结合相适应的思政课实践教学体系，以发挥二者间的叠加教学效应。这既是高职培养“全面发展和适应社会需要”的人的题中应有之意，也是高职思政课实践教学改革要着力探索的一种新型方式和途径。     

高职教育统计专业应注重技能培养

在统计课教学中，要设置基本技能标准，积极改进教学方法，强化实践教学环节，以此来增强学生基本技能，以实现高职学生的培养目标。     

高端技术技能型本科人才培养目标定位——以土木工程专业人才培养为例

随着我国经济发展方式的变化和产业结构的调整,传统职业教育人才培养已不能完全满足现代工业化发展对人才的要求。高端技术技能型本科是近年来为适应现代社会、经济和技术发展的需要提出的一种新的教育类型。目前,高端技术技能型本科人才培养相关的理论研究及试行经验均未成熟,普遍存在对高端技术技能型人才培养的目标定位、内涵等认识不够清楚的问题。本文依托四川省教育厅关于开展高端技术技能型本科人才培养改革试点的背景,通过对普通本科、应用型本科、高职专科三种层次的人才培养目标对比分析,并结合土木工程专业特点,初步提出了土木工程专业高端技术技能型本科人才培养目标定位,揭示了其内涵。相关成果可以为高端技术技能型人才培养提供借鉴参考。

Dribbling determinants in sub-elite youth soccer players

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s^?1, P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.
