人民币汇率失衡及贸易壁垒对我国出口行业影响异质性研究

贸易摩擦、新冠疫情使我国经济贸易面临严峻挑战,人民币汇率波动及贸易壁垒将常态化地影响我国出口贸易.在加快形成以国内大循环为主体、国内国际双循环相互促进的新发展格局背景下,文章基于HS分类原则,选取WTO等机构的贸易数据,通过构建BEER模型测算了人民币汇率失衡程度;通过建立固定效应面板模型研究了人民币汇率失衡及贸易壁垒双因素对我国出口行业影响的异质性.研究表明:人民币汇率失衡对我国出口贸易整体上具有显著负向影响,非关税壁垒对我国出口贸易整体上具有显著正向影响;关税和非关税构成的贸易壁垒与人民币汇率失衡双因素对我国出口贸易具有显著抑制作用,并对不同出口行业的影响存在异质性;人民币汇率失衡与非关税壁垒双因素对大多行业均具有显著负向影响,人民币汇率失衡与关税壁垒双因素对不同行业影响的正负效应及程度大小有异质性.因此,建议通过运行逆周期因子等完善人民币汇率自我修正机制;通过引导出口企业了解使用外汇衍生品等促进外汇衍生品市场运行机制的健全;通过加强"海外仓"建设及深耕RCEP框架下的东盟十国市场等实施出口行业差异化贸易策略;通过提升自主科技创新能力等加快出口行业产业转型升级,推动双循环,实现我国出口贸易高质量发展.

犯罪对象新议

传统刑法理论认为,犯罪对象也即行为对象,是指犯罪行为直接作用的具体的人或物。而从价值哲学的角度分析,犯罪对象和行为对象应是两个不同的概念。即:犯罪对象是指受犯罪行为侵犯而为犯罪构成所必备的能表现犯罪客体的事物,而行为对象则指犯罪行为直接作用或指向的说明行为完整性的自然存在的人或物。     

CELEBRATING HETEROGENEITY?: A survey of female ICT professionals in England

This paper introduces key findings from a large-scale, online survey of women in the ICT industry across England undertaken between October 2004 and October 2005. Placed in a theoretical framework which draws on critical perspectives from within information systems (IS), and the sociology of gender and of technology, the authors examine some of the issues faced by female ICT professionals. The context for this paper is the ongoing under-representation of women in the ICT industry in England, and the difficulties that the industry is having retaining women, particularly at senior levels. Data are presented on the demographic composition of women in the ICT industry in England. In addition the authors focus on their management of domestic and caring responsibilities, including changes in working practices they have experienced as a result of these responsibilities. These data are particularly pertinent given current government and industry debates regarding the 'work-life balance' and 'flexible working' in the ICT industry, partially as a response to the need for a more diverse ICT workforce. Alongside information on the career histories of female ICT professionals, the authors review their perceptions of pay and reward packages, working environments, the skills they hold, and the recognition they may or may not receive in their current posts. They present reports of a 'long-hours' and 'presenteeism' culture in the ICT industry, and the existence of gendered informal networks in ICT. They also examine female ICT professionals' perceptions of the current and future-possible image of the industry. The findings highlight the continued masculinization of ICT work, and some of the difficulties faced by women working in what remain statistically and symbolically male-dominated environments.     

论英语语言课程设计中的需求分析

界定需求要从目标和目的两个方面进行,这两个方面是我们发展测试、材料、教学活动、评价策略的基础。因此需求分析是语言课程建设不可分割的一部分。本文重点介绍了英语语言课程设计中需求分析的方法及步骤。目的在于强调需求分析的重要性,以及需求分析对于教师改进教学方法、提高教学效果、提高学生学习的主动性和积极性的重要意义。     

翻译的等效性:一个相对的概念

在英汉互译中,设法使原语与译语达到几乎完全的等效,就成了译者为之竭尽全力奋斗的目标。它要求译者融会多方面的知识,考虑多种因素,结合自己各方面的才能,综合运用各方面的阅历、技巧和文化视点的转换构思。它是翻译领域中要求较高的一种技艺和技巧。文章从词汇表达,句子构建和语篇处理的角度,谈翻译的等效性。

Physiologically Based Liver Modeling and Risk Assessment

Because of the inherent complexity of biological systems, there is often a choice between a number of apparently equally applicable physiologically based models to describe uptake and metabolism processes in toxicology or risk assessment. These models may fit the particular data sets of interest equally well, but may give quite different parameter estimates or predictions under different (extrapolated) conditions. Such competing models can be discriminated by a number of methods, including potential refutation by means of strategic experiments, and their ability to suitably incorporate all relevant physiological processes. For illustration, three currently used models for steady-state hepatic elimination--the venous equilibration model, the parallel tube model, and the distributed sinusoidal perfusion model--are reviewed and compared with particular reference to their application in the area of risk assessment. The ability of each of the models to describe and incorporate such physiological processes as protein binding, precursor-metabolite relations and hepatic zones of elimination, capillary recruitment, capillary heterogeneity, and intrahepatic shunting is discussed. Differences between the models in hepatic parameter estimation, extrapolation to different conditions, and interspecies scaling are discussed, and criteria for choosing one model over the others are presented. In this case, the distributed model provides the most general framework for describing physiological processes taking place in the liver, and has so far not been experimentally refuted, as have the other two models. These simpler models may, however, provide useful bounds on parameter estimates and on extrapolations and risk assessments.     

班主任的师德和工作方法探讨

班主任是一个班集体的核心 ,班主任工作做的好坏直接影响学生综合素质的高低。对于一名优秀的班主任而言 ,具有高尚的师德是做好班主任工作的首要条件 ;良好的工作方法是做好班主任工作的必要条件 ,把学生宿舍建设成为“四个阵地”,即政治思想教育阵地、文明道德行为的养成阵地、科学文化知识的学习阵地和课余文化的活动阵地 ,以此促进优秀班集体的形成。
