Analysing behavioural differences between e- and m-bookers in hotel booking

This study analysed the behavioural differences between e- and m-bookers in online hotel booking. The theoretical relationships among functionality and usability, perceived value for money and time, and satisfaction and loyalty were analysed based on the quality–satisfaction–loyalty framework. Results from a sample of 431 and 401 e- and m-bookers, respectively, affirmed the similarities and differences between the two types of bookers. Results also showed that e- and m-bookers substantially differ in their perceptions on functionality and usability performance, perceived value for money and relative importance of functionality and usability in online hotel booking. Moreover, the findings revealed the moderating effects of perceived value for money and time on the satisfaction–loyalty link among m-bookers.

How Does Using a Mobile Device Change Investors’ Reactions to Firm Disclosures?

I examine how characteristics of investors’ information access tools change investors’ reactions to firm disclosures. I examine my research question in the context of information choice (i.e., allowing investors to choose the order of information and sections to read within a disclosure) and spatial layout (i.e., how information is displayed when viewing the disclosure). Results of an experiment are consistent with information choice improving investors’ judgments if the disclosure is viewed on a computer screen. Conversely, and consistent with cognitive overload, information choice harms investors’ judgments if the disclosure is viewed on a smaller screen, such as that of a mobile device. Follow-up experiments show that changing the disclosure presentation to reduce the need to scroll is one way to improve investors’ judgments on a smaller (or mobile) screen. My findings caution firms and regulators about expanding information choice within disclosures without considering the screen size used to access the disclosure.     

Mobile money,risk sharing,and educational investment: Panel evidence from rural Uganda

We examine the impact of the rapidly expanding mobile banking service “mobile money” on rural households' ability to smooth investment in schooling after a negative shock. We find that a negative shock induces a 9.3‐percentage point decrease in per school‐age child educational expenditure for households who do not use mobile money compared to an 8.3‐percentage point decrease for households that have adopted mobile money. The underlying mechanism is an increase in remittance receipt and the diversity of senders owing to the reduction in transactions cost provided by mobile money. We show that our results are robust to alternative mechanisms. We use the expansion in mobile money agent network as an exogenous variation in access to mobile money.

Three generations of Telework: New ICTs and the (R)evolution from Home Office to Virtual Office

‘New ICTs’, such as smartphones and tablet computers, have revolutionised work and life in the 21st Century. Crucial to this development is the detachment of work from traditional office spaces. Today's office work is often supported by Internet connections, and thus can be done from anywhere at any time. Research on detachment of work from the employer's premises actually dates back to the previous century. In the 1970s and 1980s, Jack Nilles and Allan Toffler predicted that work of the future would be relocated into or nearby employees’ homes with the help of technology, called ‘Telework’. Analysing technological advancements—the enabling forces of change in this context—over four decades sheds new light on this term: they have fostered the evolution of Telework in distinct stages or ‘generations’. Today's various location‐independent, technology‐enabled new ways of working are all part of the same revolution in the inter‐relationship between paid work and personal life.     

人口流动对区域创新能力的影响与空间效应——长江经济带三大城市群70城市的例证

人口流动改变了创新资源的空间配置,会对流入地和流出地的创新能力产生不同的影响,创新能力的空间相关性则导致人口流动对区域创新能力的影响具有空间效应。采用2006—2020年长江经济带三大城市群70个城市的面板数据,运用普通面板模型和空间杜宾模型分析表明：人口流入会促进本地创新,而人口流出会抑制本地创新;本地和邻近地区的人口净流入均有利于创新能力提升,人口流动影响区域创新能力具有显著的空间溢出效应;人口流动促进人口净流入地的创新能力并产生正向空间溢出效应,但会抑制人口净流出地的创新能力并产生负向空间溢出效应;劳动力人口流入正向影响创新能力并具有正向空间溢出效应,老年人口流入对创新能力的影响及空间效应不显著,但老年人口流入达到一定规模后有利于创新能力提升;人口流动对人口规模较大城市和距离中心城市较近城市创新能力的促进作用和空间溢出效应较强,不同的城市群也存在显著的异质性。因此,应采取差别化的人口流动引导政策,充分挖掘各年龄段流动人口的潜力,有效促进各地区的创新发展。     

基于等效离子防雷技术的移动通信基站雷电防御方法

传统的防雷方法主要采用避雷针、地网等手段来引导雷电流入大地,然而这种方法在应对电磁脉冲的干扰方面较为薄弱,导致防雷效果并不好。为此提出基于等效离子防雷技术的移动通信基站雷电防御方法。首先,确定等效离子阻雷的安装位置,以便很好地覆盖基站区域;其次,设置大气电场雷电阈值,实时监测雷电活动;第三,实施雷电距离警报,及时发出预警信息;最后,利用等效离子防雷技术改变雷电自然路径,降低雷电对基站的潜在威胁。实验结果表明：与避雷针和接地防雷技术相比,基于等效离子防雷技术的移动通信基站雷电防御方法能有效吸收和中和电磁脉冲,降低雷电对电子设备的干扰和损坏,防雷效果更好,具有实际应用价值。
