农产品电商集群企业地理邻近性对协同创新绩效的影响

基于知识治理视角,构建农产品电商集群企业地理邻近性、知识治理、知识共享和协同创新绩效关系的链式中介模型,并引入网络关系强度作为调节变量,结合341家农产品电商集群企业的调研数据,采用多层次回归和Bootstrap分析方法,分析地理邻近性对协同创新绩效的直接作用,检验知识治理和知识共享的独立中介作用和链式中介作用,以及网络关系强度的调节作用。结果表明：地理邻近性正向影响协同创新绩效;知识治理在地理邻近性和协同创新绩效间发挥中介作用;知识共享在知识治理和协同创新绩效间发挥中介作用;知识治理和知识共享在地理邻近性和协同创新绩效间发挥链式中介作用;网络关系强度正向调节正式知识治理和显性知识共享的链式中介作用。因此,农产品电商集群企业要把握数字经济发展契机,善于利用集群区位优势和产业资源,激发正式知识治理和非正式知识治理的双重效应,与合作企业建立良好的知识共享关系,实现高质量协同创新发展。     

Does the sense of the geographic proximity of a requester influence donation? Three evaluations in field studies

It has been reported that familiarity or incidental similarities with a stranger influenced an individual’s behavior. However, the effect of the sense of geographical proximity believing that someone comes from the same area that somebody has never been examined. Three field experiments examined this effect on donations to humanitarian organizations. In the first study, participants were asked by a confederate to donate food products to a humanitarian organization. In Study 2, participants were asked by confederates to donate money for children. In Study 3, donation boxes were displayed in bakeries with a message that invited customers to donate money for children. In all the studies, participants were led to believe that they would be helping people in need or people who live in their national or local geographic area. Results showed that donations were higher in the geographical proximity condition. This “neighborhood effect” was discussed.     

“形似与神似”再探

中国的翻译界将艺术创作领域内的"形似"、"神似"借来,作为处理译文的两种方法,并曾产生了不小的争论.追溯历史,有比较固定内涵的"形"、"神"概念,大约盛行于春秋战国,深入于两汉,而分化于晋以后.争执起因是很多学人心目中的"形"与"神"是截然分开的两个单一概念.实际上,"形"与"神"是密切相关的两个多层次概念.最理想的情况无疑是形神兼备.在不能两全时,译者必然面临抉择.在这种情况下,译者试图表达作者意图和保证原作声誉的任何努力都应得到应有的肯定.     

科学联想：科技创新的钥匙

科学联想是在科学研究过程中,人们根据事物之间的某种联系,由一种事物想到另一种相关事物的思维活动。按照科学联想的性质和特点的不同,科学联想可分为接近联想、对比联想、类比联想和因果联想四种类型。科学联想是一种重要的科技创新思维,加强联想能力的训练是提高联想能力的有效途径。     

跨国专利合作网络中技术接近性的调节作用研究

技术接近性对于企业间的跨国专利合作具有重要作用.基于多维接近性整体分析框架,采用中国电力系统技术领域2000年至2008年国外专利合作数据,分析技术接近性对其他接近性的调节作用.通过构造112家中外企业的专利合作网络,运用QAP网络回归方法实证检验跨国专利合作网络中技术接近性在地理接近性和社会接近性影响专利合作网络中节点连接距离和连接重要性过程中的调节作用.研究结果表明,在考虑多维接近性共同作用时,技术接近性对网络节点的连接距离和连接重要性具有重要影响,有助于节点之间构筑较短的连接渠道并形成较为重要的合作关系.除此以外,技术接近性还能正向调节社会接近性对连接重要性的正效应,但对于社会接近性与连接距离之间的关系没有显著的影响.由此验证了技术接近性可以影响其他接近性与跨国知识合作关系的基本假设,为进一步揭示不同接近性之间的相互作用机制提供了理论基础.     

The proximity filter: the effect of distance on media coverage of the Christchurch mosque attacks

ABSTRACT

The intense media coverage in New Zealand and Australia of the Christchurch mosque attacks exhibited significant disparity in editorial decision-making between the two countries. This research interrogates the different approaches taken in newsrooms and how these differences were manifested in broadcasts and publications. New Zealand media were focused largely on empathetic coverage of victims and resisted the alleged gunman's attempts to publicise his cause while their Australian counterparts showed no such reluctance and ran extended coverage of the alleged perpetrator, along with material ruled objectionable in New Zealand. It finds the editorial focus in each case exhibits the effect of proximity, identified in literature on empirical ethical decision-making as a factor in applied ethicality. The authors conclude that a proximity filter was used by New Zealand media who identified the victims as part of their own community, but the events of 15 March 2019 were seen as ‘foreign’ by Australian journalists who used perceived distance as justification for extremely graphic content.

基于专利引用的国际性技术外溢实证研究

采用专利跨国引用作为国际性技术外溢的代理变量,基于美国国家经济研究局专利引用数据库分析中国发明专利技术的现状和特征;依据该数据库中6大类36个专利的细分类别,计算1985年～1999年中国与11个创新型国家(地区)的技术相似度;运用技术知识存量替代技术知识流量,测算中国1985年～2004年的对外技术依存度,综合分析技术相似性、对外技术依存度、地理距离和语言等因素对中国通过专利引用获取国际性外溢技术的影响,利用负二项回归方法对影响中国专利引用的相关因素进行计量研究。研究结果表明,技术相似度与跨国专利引用之间不存在显著性正相关关系,对外技术依存度、语言差异均与跨国专利引用显著负相关,地理距离与跨国专利引用显著正相关。     

Tavern proximity,tavern density and socio-economic status as predictors of assault occurrence within New Zealand: a temporal comparison

This paper investigates how the associations between tavern proximity, tavern density and area unit socio-economic status with assault occurrence vary in a temporal sense. Using New Zealand Police data specifying the day, time and location of assaults in 2016 and Ministry of Justice data specifying the location of on-licenced taverns, we construct logistic regression models to determine how well tavern proximity, tavern density and socio-economic status predict the occurrence of assaults at peak (Fri 22:00–Sat 03:00 and Sat 22:00–Sun 03:00) and off-peak times. An equal-sized sample of traffic generators (public venues whose primary function is not the sale of alcohol) is constructed and similar procedures applied. We find that tavern proximity and tavern density are stronger predictors of assault occurrence at peak, compared to off-peak, times. Conversely, socio-economic status is a better predictor of assault occurrence at off-peak times. We also find that whilst tavern proximity and density are stronger predictors of assault occurrence relative to traffic generator proximity and density at peak times, the opposite is true at off-peak times. These results suggest that in order to minimise alcohol-related harm, there is a need for policy-makers to take into account the temporal nature of these relationships.
