先秦婚仪婚俗探微

《仪礼.士昏礼》问名仪式中“敢请女为谁氏”的提问包含着丰富的礼教内涵,郑注仅理解为“谦也”,大失其旨。春秋时代“择偶自由”、“性观念开放”的结论与史实差距甚远,造成这种偏见的原因在于未能在概念上将周王朝主流婚礼与各种原因所造成的支流婚俗作明晰区分。     

服饰与禁欲

服饰文化起因的说法有多种,但不论哪一种都存在着这样或那样令人无法完全接受的地方。从人类自身的起源和节育等方面的推测来看,服饰文化的源起应与人类的性禁忌有关。     

汉语中的性别歧视

语言是人类最重要的交际工具,它与社会生活联系十分紧密。人类的认识成果、社会心理、价值观念等,都会在语言中有所反映。同样,一些封建思想也会在语言中留下痕迹。对女性的性别歧视就是其中之一。通过造字、构词、词序这三个角度来谈谈汉语中的性别歧视问题。     

论祥子悲剧命运之根源

文章从三个角度对祥子的悲剧进行了探讨,认为他的悲剧根源在于三对矛盾:对身体的过分依赖同半殖民地、半封建的社会之间的矛盾、对性的需求和错误认识之间的矛盾,以及自给自足的思想观念同带有商品经济特点的城市生活之间的矛盾。     

言语风格的性别差异

作为文化色彩较浓的两性角色在社会的许多方面都体现出其差异性,在言语交际中,由于性别的不同形成了不同的言语风格。本文就男女两性的言语风格从话语主题、话语量和话语得体性,即遵从礼貌准则和合作原则的差异等方面,探讨两性的社会地位的差异和造成此差异的社会根源。     

Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.     

出生性别比的统计质量控制

本文试图突破"出生人口性别比计算必须依据大样本"的观点.在限定条件下,采用小样本推断方法,借助统计质量控制,对出生人口性别进行实时统计分析。     

不同强度运动对女运动员月经周期性激素水平的影响及调整对策

通过对近十年来相关资料的分析与研究,结果表明：女运动员经期进行大强度训练易引起性激素水平显著性变化,尤其是月经期不良生理反应较大,经期进行中强度训练不但不易引起不良的生理反应,而且对运动有益。最后,提出一些可行性预防措施与建议,以供教练员与运动员参考。     

基于单片机的脉冲电源控制系统设计

硅片的电火花线切割是一种新型的工艺方法,由于硅片的高电阻率特点,脉冲电源的参数与传统线切割设备有较大不同。通过采用MCS51系列的单片机,设计一种基于高压直流电源改进为脉冲电源的控制系统,应用到高速走丝线切割机床上来对工件进行试切,可以取得理想的切割效果。     

A parallel memory architecture for video coding

To efficiently exploit the performance of single instruction multiple data （SIMD） architectures for video coding, a parallel memory architecture with power-of-two memory modules is proposed. It employs two novel skewing schemes to provide conflict-free access to adjacent elements （8-bit and 16-bit data types） or with power-of-two intervals in both horizontal and vertical directions, which were not possible in previous parallel memory architectures. Area consumptions and delay estimations are given respectively with 4, 8 and 16 memory modules. Under a 0.18-pm CMOS technology, the synthesis results show that the proposed system can achieve 230 MHz clock frequency with 16 memory modules at the cost of 19k gates when read and write latencies are 3 and 2 clock cycles, respectively. We implement the proposed parallel memory architecture on a video signal processor （VSP）. The results show that VSP enhanced with the proposed architecture achieves 1.28× speedups for H.264 real-time decoding.
