一种提高切梗丝机烟梗压实性能的方法研究

通过增设梗签回收装置,解决了切梗丝时刀门处烟梗不规则而形成的"空洞"现象,减少了"空洞"造成的烟梗经刀门时压实力的突然释放而由"切削力"变为"刮削力",从而将烟梗刮出刀门区域形成的"梗签".通过烟梗压实性能的提高,一方面减少了梗签造成的原材料消耗;另一方面减少了处理梗签采用压棒后掩埋对土壤环境的影响.符合国家绿色发展和...     

Transmission of China's Shocks to the BRIS Countries

This paper investigates the effects of China on the BRIS countries, namely Brazil, Russia, India and South Africa. We identify Chinese supply and demand shocks and assess their transmission to BRIS in a structural dynamic factor model framework estimated over the period 1995Q2‐2009Q4. The findings show that Chinese supply shocks are more important than its demand shocks. Supply shocks produce positive and significant output responses in all BRIS countries. And while these supply shocks have a permanent impact on the BRIS countries, the effects of demand shocks are short‐lived. Both supply and demand shocks are transmitted through trade rather than financial linkages. However, the responses of the BRIS countries are heterogeneous and therefore require country‐specific policy responses.     

认知学视角下的多维度英语词汇记忆

词汇是语言的重要组成部分。词汇量的匮乏是语言学习者进行有效语言交际的首要障碍。如何使学习者在一个没有二语的语言环境下有效地学习大量的词汇始终是值得研究的。随着认知语言学的不断发展,对词汇学习的认知研究也日趋为人们所关注。本文从认知语言学中的原型理论、通道转换理论的认知视角,初步探讨了英语词汇记忆的方法及策略。     

藏区农牧民医疗救助体系运行效果及其评价指标设计——以甘肃甘南藏族自治州为例

因病致贫已经成为制约藏区经济社会发展的主要因素之一,实施制度化的医疗救助以帮助藏区农牧民尽快摆脱贫困,成为政府做好民族工作的重要任务。本文全面阐述了贫困与民族发展之间的密切关系,认识到藏区农牧民医疗救助由于经济、社会等因素的影响,导致医疗救助体系运行不规范,未能达到既定的目标和预期效果,迫切需要对藏区农牧民医疗救助体系的运行效果进行评价,逐步提高藏区农牧民医疗救助的水平。本文运用层次分析方式,选择具有藏区典型特征的甘肃甘南藏族自治州为研究对象,采用鱼骨图来表述藏区农牧民医疗救助体系运行效果,并以此为依据设计评价指标,以期能够更好地保障该体系的良好运行,促进藏区经济社会的稳步发展。     

企业资源标识的方法研究

在企业运作过程中,企业会使用各种资源。资源标识是一种高效明示该资源特征属性的信息形式,但目前国内外还没有文献对企业资源标识这种简述形式进行一般性地理论定义和描述的相关研究。本文通过建立企业资源标识的概念模型、集合结构模型及拼图结构模型,从理论上一般性地定义和描述企业资源标识,并归纳出13条标识的基本原则,为分析、设计和管理企业资源标识奠定一定的理论基础,这是企业微观管理研究的一个原创性探索。

A Typology of Communicative Strategies in Online Privacy Policies: Ethics, Power and Informed Consent

The opaque use of data collection methods on the WWW has given rise to privacy concerns among Internet users. Privacy policies on websites may ease these concerns, if they communicate clearly and unequivocally when, how and for what purpose data are collected, used or shared. This paper examines privacy policies from a linguistic angle to determine whether the language of these documents is adequate for communicating data-handling practices in a manner that enables informed consent on the part of the user. The findings highlight that corporate privacy policies obfuscate, enhance and mitigate unethical data handling practices and use persuasive appeals to increase companies’ trustworthiness. The communicative strategies identified provide starting points for redesigning existing privacy statements with a view to communicating data handling practices in a more transparent and responsible manner, laying the groundwork for informed consent.     

The coevolutionary process of restaurant CSR in the time of mega disruption

This study investigates how US foodservice conglomerates have embarked on corporate social responsibility (CSR) measures to circumvent dire situations during the COVID-19 pandemic. It explores the evolution of CSR practices from restaurant enterprises to rescue and salvage their stakeholders. By analyzing press releases from ten restaurant chains in three different crisis phases (incubation, acceleration, and climax) through corpus linguistics, we identify a CSR progression mechanism that coevolves with the aftermath of the crisis among their stakeholders. This study improvises the CSR- as-process view to highlight the time-variant dynamic nature of CSR development over the course of major disruption.     

EFL写作中代词误用的认知分析

在EFL写作中出现人称代词视角转换混乱、指代不明、物主代词省略及忽略名词与代词的认知差异等现象,从认知语言学的相关理论来看,这是由于代词的使用受到认知方式的制约。教师应有的放矢地指导学生正确运用代词。     

The impact of traffic sign deficit on road traffic accidents in Nigeria

This study assesses the impact of traffic sign deficit on road traffic accidents in Nigeria. The participants were 720 commercial vehicle drivers. While simple random sampling was used to select 6 out of 137 federal highways, stratified random sampling was used to select six categories of commercial vehicle drivers. The study used qual-dominant mixed methods approach comprising key informant interviews; group interviews; field observation; policy appraisal and secondary literature on traffic signs. Result shows that the failure of government to provide and maintain traffic signs in order to guide road users through the numerous accident black spots on the highways is the major cause of road accidents in Nigeria. The study argues that provision and maintenance of traffic signs present opportunity to promoting safety on the highways and achieving the sustainable development goals.
