政府资助国际合作效果的国别和学科差异研究

以收录于Web…of…Science的国家自然科学基金资助论文为对象,从高被引论文和平均引用影响两个视角,评价我国与G7国家的合作效果。研究表明,美国是第一大合作伙伴,加拿大、日本、英国、德国和法国与我国的合作规模相当,意大利与我国合作最少;在提升国际合作影响力(高被引论文份额和平均引用影响)方面,NSFC对数学、化学与化工、以及物理学与材料科学领域的提升作用明显,但这种提升效果因合作国家不同而异;NSFC资助对国际合作影响力提升作用较好的领域也是我国总体上实力相对较强的领域,而需要付出更大努力的是我国影响力远低于世界平均水平的领域(如环境与生态学、神经科学与行为学、微生物学、分子生物学与遗传学、以及临床医学等),NSFC资助的国际合作效果甚至不及非NSFC资助的国际合作。文末提出资助政策建议。     

Demystifying blockchain: A critical analysis of challenges,applications and opportunities

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.     

Business models shifts: Impact of Covid-19

No amount of crystal ball gazing may help us fathom the full impact of the Covid-19 (C-19) crisis on business organizations in a distinct manner. Given the lack of precedence, any such analyses seem to demand routine revisions as we progress further up the “number of infected” curve. Most countries of the world have imposed restrictions on social congregations or even people working in close proximity to each other. Industries that produce and deliver information products and services therefore, have continued to function while those that manufacture physical products especially labor-intensive firms were forced to minimize operations or temporarily shut down. However, in most countries, physical products which were essential in nature were reluctantly permitted to be manufactured given the need for them in people’s everyday life. In this viewpoint, I draw upon three dimensions – information intensity of product/service, information intensity of process/value chain; along with a third dimension – essential nature of the product/service to help understand the immediate implications of C-19. I also present some anecdotal evidences of attempts to alter business models in these circumstances in order to address the challenges that certain product characteristics impose but at the same capitalize on the business opportunities presented by the essentiality of the products.     

上海国际航运中心建设支持政策的量化评价

为增强上海国际航运中心建设支持政策的有效性,基于2009—2018年间国家及地方政府层面颁布的19个涉及上海国际航运中心建设的政策文本,应用文本挖掘方式提取评价指标,构建PMC指数模型对政策进行量化评价。分别选取3项针对性政策和3项辅助性政策作为评价对象进行实证分析,结果表明:针对性政策的PMC指数总得分高于辅助性政策的PMC指数总得分,且随着上海国际航运中心建设的不断推进,其引导作用不断加强;辅助性政策虽然只考虑到上海国际航运中心的部分建设需求,但在保障激励等方面给予了高度重视。

A meaning-making model of post-migration growth for mainland Chinese university students in Hong Kong

Studies of stress-related growth have demonstrated the central role of meaning-making processes in the occurrence of growth following stressful life experiences, but few have examined its role in the context of acculturation. This study developed and tested a meaning-making model of post-migration growth using bootstrap-based mediation analysis with a sample of 489 mainland Chinese university students in Hong Kong. The data were collected through an online cross-sectional survey. The results showed that acculturative stressor was a significant risk factor and that sense-making coping and core belief re-examination acted as significant protective factors for post-migration growth. Sense-making coping and core belief re-examination, in sequence, partially mediated the relationship between acculturative stressor and post-migration growth. This model demonstrates the importance of the cognitive processing of meaning-making in Chinese students’ post-migration growth.     

美国在网络主权问题上的立场变化及启示

[目的/意义]在网络空间这个新颖而又无处不在的领域中,主权原则如何运作一直是国家实践和学界理论研究中的硬核问题。厘清美国在该问题上的立场变化对我国参与网络空间国际治理具有积极意义。[方法/过程]利用历史分析法、文献研究法和对比分析法对美国《情报活动中的国际法律问题评估》(1999年)、《网络行动国际法塔林手册2.0》和《在军事行动中使用网络能力的国际法框架》(2017年)进行法律考察。[结果/结论]研究表明,为应对美国在网络主权问题上的立场转变,我国应坚持领土主权原则的拘束力,平等地尊重各国网络主权,并积极参与网络空间国际规则制定的实践,推动网络空间命运共同体理念的国际法构建。     

Business communication as cultural text: Exchange and feedback of promotional video clips

Our research is a response to the need to improve the understanding of the complexity of global professional communication. To investigate the complex cultural interpretations that producers and audiences apply to professional texts, we developed a two-year interactive project. Business students in New Zealand and Israel produced promotional “texts” – video clips to promote a university program – which they exchanged with their counterparts overseas to receive feedback. We adapted models of home-made visual communication and advertising which used the categories of participants, settings, topics, and style, to analyze the eight clips. Emergent findings suggested two more categories – information and language – as important analytical tools. Variables of age, gender, intra- and intercultural differences, and (cultural) context also resulted in student audiences’ multiple interpretations of the texts. The outcomes indicate the need to extend the culture-in-context approach for a “situation focused communication approach,” where the primary focus is a group of producers and their audience as they produce and interpret a professional text. This approach also foregrounds contextual variables and a plural understanding of culture to accommodate the potential for miscommunication of business and professional texts in pluricultural contexts.     

中国茶叶国际竞争力分析与政策建议

本文运用FAO的统计资料，利用国际市场占有率、显示性比较优势、生产者价格指数3个显性评价指标和单产这个隐性评价指标，测算了20世纪80年代以来中国与印度、斯里兰卡、肯尼亚和印尼茶叶的国际竞争力变化。分析表明，中国茶叶在4个评价指标上基本处于劣势地位,尤其表现在显示性比较优势、生产者价格指数和单产3个指标上。本文基于波特教授的“国家钻石”模型中国际竞争力的5个决定因素，提出提升中国茶叶国际竞争力的相应对策与建议:①在要素禀赋层面，重点解决低下的要素的生产率问题，要创造新的生产要素并将之导入茶叶产业;②在公司层面，要顺应国际茶叶竞争潮流，推行联合规模经营，走名茶名牌之路;③在关联产业层面，要积极发展专业化生产，为茶叶生产提供专业性的生产资料;④在需求层面，要在稳固传统市场的基础上，大力开拓新兴市场，降低出口市场的集中度;⑤在政府层面，要明确在WTO框架下的职能边界，重点解决好茶叶的标准化问题，从源头和末端对混乱的茶叶出口秩序进行有效的治理。与其它4个层面相比，对茶叶产业而言，政府的行为可能更为关键，因为中国的实际情况决定了这一点。
