中国装备制造业出口品国内技术含量的动态变迁及国际比较——基于非竞争型投入产出表的研究

利用非竞争型投入产出表和技术含量指数,测算了中国、德国、日本、美国装备制造业出口品的复合技术含量、国内技术含量和国内技术含量指数,发现中国装备制造业出口品技术含量大致经历了两个阶段,分别是1995—2003年的平稳上升阶段和2003—2011年的国内技术含量指数递减阶段。与德国、日本和美国的比较发现,无论装备制造业整体还是细分行业,中国装备制造业出口品的国内技术含量与主要发达国家间存在着明显的差距。最后,在上述分析基础上,提出了提高中国装备制造业出口品国内技术含量的政策建议。     

Environmental Reporting of Global Corporations: A Content Analysis based on Website Disclosures

Today, more corporations disclose information about their environmental performance in response to stakeholder demands of environmental responsibility and accountability. What information do corporations disclose on their websites? This paper investigates the environmental management policies and practices of the 200 largest corporations in the world. Based on a content analysis of the environmental reports of Fortune’s Global 200 companies, this research analyzes the content of corporate environmental disclosures with respect to the following seven areas: environmental planning considerations, top management support to the institutionalization of environmental concerns, environmental structures and organizing specifics, environmental leadership activities, environmental control, external validations or certifications of environmental programs, and forms of corporate environmental disclosures.     

Social Embeddedness in Electronic Negotiations

This study contributes to electronic negotiation research by analyzing the role of social embeddedness of actors in a controlled laboratory experiment. In particular, we analyze the effect of prior negotiator relationship in different conflict levels in web-based negotiations. We hypothesize that with increasing intensity of conflicts, negotiators who have a personal relationship use more value creating strategies compared to anonymous negotiators. As a consequence, we also hypothesize to find fewer impasses in electronic negotiations involving subjects who are socially embedded. Our results confirm that, in fact, in severe conflicts socially embedded actors reach significantly more agreements than subjects of the control group while such an effect is not found in weak conflict situations. These findings are related to more yielding between embedded actors but not to more value creating behavior. From these results, we can conclude that socially embedded negotiators better manage to reach agreements in difficult situations. Furthermore, an institutionalized pre-negotiation phase which allows negotiators to establish a personal relationship can counteract the threat of impasses.     

夏季车内存放时间对开封后瓶装饮用矿泉水中亚硝酸盐含量及菌落总数的影响

目的:探究夏季汽车内瓶装饮用矿泉水开封后的存放时间对水中亚硝酸盐含量及菌落总数的影响.方法:夏季将开封后的瓶装饮用矿泉水放置于汽车内,在第1 d、第3 d、第7 d和第14 d分别测定水中的NO2-含量及菌落总数.检验标准参考《食品安全国家标准饮用天然矿泉水检验方法》(GB 8538—2016)和《生活饮用水标准检验方法微生物指标》(GB/T 5750.12—2006).结果:开封后的瓶装饮用矿泉水在汽车内存放3 d后,菌落总数呈现轻微上升,其菌落总数平均值为7.5 CFU·mL-1、NO2-含量无明显变化;存放7 d后,其菌落总数、NO2-含量呈现急剧上升,其菌落总数平均值为95 CFU·mL-1,NO2-含量为0.125 mg·L-1;存放14 d后,其菌落总数、NO2-含量呈现大幅度上升,其菌落总数平均值为355 CFU·mL-1,NO2-含量为0.254 mg·L-1.结论:开封后的瓶装饮用矿泉水在夏季汽车内的存放时间为7 d时,其菌落数量仍符合《生活饮用水卫生标准》的限值(100 CFU·mL-1)要求,但接近临界值;NO2-含量不符合饮用天然矿泉水标准限值(0.005 mg·L-1),因此开封后的瓶装饮用矿泉水在夏季汽车内的存放时间接近或超过7 d时,不建议直接饮用.     

Looking Ahead—Future Issues when Reflecting on the Place of the iConsumer in Consumer Law and Copyright Law

The following is a brief report of the discussion and main comments that were made during a workshop ‘The place of the iConsumer in EU and US law—protecting consumers of copyright protected content’, held in Amsterdam on 14 and 15 of December 2007. The workshop was part of a series of joint events organised by the Berkeley Centre for Law and Technology, University of California (BCLT) and the Institute for Information Law (IViR), University of Amsterdam on copyright and a follow-up to the conference on ‘Copyright, digital rights management technology and consumer protection’ that was held at the UC Berkeley in March 2007. The main goal of the workshop was to confront a consumer law approach with the more commonly discussed approach of internalising user-related questions directly into copyright law. To this end, a selected group of European and US experts in both fields, copyright law and consumer law, were invited. The participants were then asked to share their thoughts and views from the different fields of law with regard to a number of main statements given by the organisers. The transatlantic perspective further added to the discussion. The main purpose of this report is to point to a number of issues that, according to the workshop participants, should be taken into account in future discussions concerning the legal position of the iConsumer. This report summarises the discussion along the three statements that the organisers asked participants to consider. The report gives some background information for each of the statements, to then describe the main arguments made during the workshop, to the extent that this discussion has not already been internalised in the papers that are part of this special JCP issue.

Profiling tourists based on their perceptions of the trustworthiness of different types of peer-to-peer applications

This research profiles tourists based on the extent to which they trust user-generated content (UGC) uploaded in different types of peer-to-peer applications, also considering their socio-demographic characteristics, frequency of travel and motivations for using the Internet and UGC when making their travel choices. For this purpose, latent class segmentation was applied on a sample of 609 Italian tourists and three different clusters were identified, namely: “distrustful tourists”, “untrusted tourists” and “social web tourists”. The findings suggest that hospitality marketers should improve their social media strategy by focusing their attention on Travel 2.0 applications according to the socio-demographic and behavioural characteristics of their target market.     

形式实验主义与主题现实主义——从《金色笔记》试探索小说的形式、内容和功能

在《金色笔记》中,莱辛将各种主题浑然成篇,为读者提供了富有个性的人物素描。作为“营造秩序、提出一种新的人生观”的预言家,她利用小说寓言了两性关系、人类社会的发展、人在未来宇宙空间的位置,并对生活作出哲学性的阐释。她还探求了小说在形式、内容和功能方面发生的变化,锐意改革：展示了以四本笔记,并穿插日记和剪报可以成篇的小说形式,从描述婚外恋的角度对小说内容进行革命。作者在笔记中也触及了社会现实,挖掘人的商业化态度,揭示了感情和财产、金钱和权力之间的关系,并运用象征,揭示了人性关系之本是彼此相依、驱散孤独,两性关系尤为如此。
