论电影《赵氏孤儿》和《关云长》对忠义思想的解构——对当代电影中历史书写的一点反思

赵氏孤儿的故事和关羽形象正因涵盖了忠义思想的精神内核,才成为传统文化中的经典。而电影《赵氏孤儿》和《关云长》对于忠义思想的解构,难免使观众产生一种阅读失落。用传统文化经典改造的商业大片能使观众一饱眼福,但如果在消费历史、消费文化的过程中得不到一点精神方面的感召,则只能让商业大片成为文化快餐而不是文化经典。     

生物细胞内不同类型钙振荡行为分岔研究

运用非线性分岔理论并结合数值仿真,针对具有快慢时间尺度的细胞内钙振荡的数学模型,研究具有重要生理意义且在实验中容易调控的单参数变化时钙离子不同类型的振荡行为。基于Izhikevich提出的分类方法,在Borghans-Dupont模型中分别得到了拟周期型簇振荡等多种簇振荡模式。     

洋快餐在中国失宠背后的思考

随着中国经济的快速增长和居民消费水平的日益提高,曾经风光十足的洋快餐,现在已“风光不再”。我们要以此为戒,在面对日益开放的市场,面对日益繁荣的经济,必须关注企业自身的建设,关注市场宏观和微观因素的影响,才能在竞争中立于不败之地。     

拱型波纹屋盖风荷载数值模拟研究

基于谐波叠加法的基本原理,结合快速傅立叶变换,利用MATLAB编写了拱型波纹屋盖多点互相关的脉动风速程序.程序运行结果表明,结构各点模拟脉动风速时程的功率谱密度函数与目标函数、风速时程的自相关函数与目标自相关函数较为一致;相邻两点之间距离越近,互相关性越强,反之,则越弱.该研究结果对进一步研究拱型波纹屋盖结构风致振动时域分析具有重要意义.

A biomechanical comparison of conventional classifications of bowling action-types in junior fast bowlers

ABSTRACT

Fast bowling is categorised into four action types: side-on, front-on, semi-open and mixed; however, little biomechanical comparison exists between action types in junior fast bowlers. This study investigated whether there are significant differences between action-type mechanics in junior fast bowlers. Three-dimensional kinematic and kinetic analyses were completed on 60 junior male fast bowlers bowling a five-over spell. Mixed-design factorial analyses of variance were used to test for differences between action-type groups across the phases of the bowling action. One kinetic difference was observed between groups, with a higher vertical ground reaction force loading rate during the front-foot contact phase in mixed and front-on compared to semi-open bowlers; no other significant group differences in joint loading occurred. Significant kinematic differences were observed between the front-on, semi-open and mixed action types during the front-foot contact phase for the elbow and trunk. Significant kinematic differences were also present for the ankle, T12-L1, elbow, trunk and pelvis during the back-foot phase. Overall, most differences in action types for junior fast bowlers occurred during the back-foot contact phase, particularly trunk rotation and T12-L1 joint angles/ranges of motion, where after similar movement patterns were utilized across groups during the front-foot contact phase.

Reviving audience studies

Audience measurement data are increasingly central to what many media corporations produce, yet much of these data are inaccessible to scholars. I therefore argue that cultural studies is in need of an audience studies revival. Fan studies continues at strength, but a wider range of audience studies is required to counter and to interrogate the occasional proclamations that companies such as Netflix, Facebook, and Google share with us about audiences and users.
