双斜撑箱形井架找正执行标准的探讨

大型钢结构箱形井架有单斜撑和双斜撑之分,根据井架结构形式的不同安装找正所执行的标准也不同,在井架安装过程中发现,同是双斜撑的井架由于其本身结构的不同,在找正时执行标准也应该区别对待.     

畸变:另类的女性存在

在现代文学中,无论是男性作家还是女性作家,都用丑化的叙述模式,书写了一群心理危机、人格缺失、行为变异的畸变女性形象,他们把这类女性置于社会、历史、文化等诸多矛盾和复杂关系之中,以性的压抑作为焦点,探究她们畸变的生成过程。情的“失时”导致了心理的畸变,也伴随着怨恨的产生,她们既因袭着传统的怨妇心理,又有着暴戾、乖张的行为方式,她们既是父权社会的受害者,又是父权社会的反抗者,还是父权社会的共谋者,在性格和命运上显示着双重悲剧。她们用变态的模式对传统女性进行报复式的解构,显示着深刻的批判性而缺乏重构性。     

Coaches as sport workers: professional agency within the employment context of elite European basketball

Increased activity of multiple stakeholders (e.g. agents and owners) have created new challenges for some coaches working in professional sports clubs. The purpose of this project was to draw attention to the normative or accepted practices inherent in sport work, some of the day-to-day realities of some coaches working in this context, and to understand how coaches’ perceptions of other stakeholders come to bear on their individual circumstances, career expectations/objectives and professional agency. Data were generated from semi-structured interviews with seven professional basketball coaches who worked in top-level European clubs. The analysis reveals the coach’s relationships between some owners and agents differed with respect to exercising professional agency, and, coach’s decisions and actions were tied to their professional ideals as well as understandings of what they need to undertake their work effectively and negotiation and/or adjustment strategies. Occasionally coach’s work practices could be viewed as antithetical to employment security, however, the presence of insecurity was at times embraced and used strategically to affect workers’ career decisions. Amid contemporary regional geo-political shifts, this work aids examinations of global sport settings, structures and issues that may contour sporting professionals’ lives.     

基于情境感知的电商平台推荐系统框架研究

[目的/意义]随着互联网行业的蓬勃发展,电商平台的用户与商品数量均呈现井喷增长。这一趋势在促进互联网经济发展的同时也为用户带来了"信息过载"的问题。电商平台如何从用户的历史行为日志中获取信息,并根据用户当前情境推荐商品,不仅是重要的理论与技术课题,同时也蕴藏着巨大的商业价值。[方法/过程]文章结合情境感知技术,提出了一种五层推荐系统框架,自底向上分为:感知层、过滤层、排序层、规则层和应用层。同时,利用淘宝APP的购物数据进行了模拟推荐实验,比较了各层次不同设计方式的推荐效果。[结果/结论]研究发现,融入了情境感知技术的推荐系统框架可以显著提高推荐的精确率,但是会削弱召回率。基于此,为电商平台提出了部分建议。     

语文阅读教学中文本细读的策略探赜

文本细读是阅读教学的一种重要方法,有利于学生领会文本内涵.教师应积极创新文本细读策略,可以先从阅读文本的关键字词入手,引导学生细读文本中的字、词、句,进而引导学生理解文本中的段落内容.教师要通过情境创设、读写结合等方式,促使学生将细读成果与写作训练结合以提高读写能力.     

低碳试点政策对城市碳排放绩效的影响评估及机制分析

低碳试点是实现中国低碳经济发展的一项重要政策,客观评价其实施效果,不仅有利于低碳试点地区更好地推进低碳工作,而且对于低碳试点政策的进一步推广具有重要意义,但低碳试点政策能否实现碳排放绩效的提升尚未得出一致的结论。本文以第二批低碳试点政策为例,基于2012—2016年的地级市面板数据,采用倾向得分匹配—双重差分（PSM-DID）方法研究低碳试点政策对降低城市碳排放强度的影响,以有效降低样本自选择及政策内生性等问题导致的处理效应偏差。研究发现：低碳试点政策对城市的碳排放强度下降具有显著且持续的推动作用;进一步的机制识别结果显示,低碳试点城市主要是通过能源效率的提高以及产业结构升级等方式实现碳强度的下降,且产业升级的效果有逐年增强的趋势,但通过城市绿地碳汇水平的提高而降低碳排放的目标尚未实现。基于此结论,本文认为中国应进一步推广低碳试点政策,积极探索低碳城市的发展模式,特别是提升宜居绿色的城市环境。     

关联语境理论对等效翻译的解释作用

关联理论是一种认知语用理论,强调语境效果,翻译则是一个认知推理的交际过程,二者有着共同的研究对象,即语言理解和表达。从关联的角度出发,实现等效翻译必须通过关联来获得最佳的语境效果的理论;再从词义确定、情景理解和文化关联三个方面论述语境在实现等效翻译中的重要作用。关联语境对等效翻译的这种解释力是相对的,而不是绝对的。     

从认知语用角度探讨话语标记语的语境构建功能

从认知语用观点出发,交际的过程也就是语境构建的过程,话语标记语在语境构建中起着明示导向与限制制约的作用,一方面明示认知假设,对语境构建具有提示功能;另一方面限制语境假设的选择,对语境构建具有制约作用,从而帮助听话人构建说话人所期待的认知语境,减少听话人在话语理解时花费的努力,获得说话人期待的语境效果。     

Simplified method of designing FIR filter with controllable center frequency

A novel simplified method is presented to design FIR filter with controllable center frequency. The properties of transfer curves for all-phase filters are illustrated under 3 windowing conditions. By combining single-window all-phase filter design steps and double phase-shift combination, a series of design formulas for point-pass filter, notch filter, band-pass filter and band-stop filter are derived, thus the design computation complexity is greatly reduced. Experiments prove that the center frequency of all the filters can be accurately specified at arbitrary position by adjusting frequency parameters m and λ.     

语境关联与翻译

作为一种跨文化交际行为,翻译的理解和表达都依赖于对语境的正确理解。关联理论中的最佳关联这一概念从认知的角度为翻译研究提供了一个新的视角。在具体的翻译活动中,译者如何求得最佳关联,正确理解原文本并生成最佳译文是建立在对相关语境的准确把握这一基础之上的。从关联理论的认知角度来研究翻译过程中译者如何实现最佳语境关联对翻译实践具有很重要的指导意义。
