Protective behavior in ride-sharing through the lens of protection motivation theory and usage situation theory     

《International Journal of Information Management》2021

The frequent occurrence of security incidents in ride-sharing is a challenge for the survival of IT-enabled ride-sharing platforms. Passengers’ protective behavior is an effective means to alleviate this issue, with benefits to both the passengers and the platforms. This study explores the mechanisms of passengers’ protective behavior in the ride-sharing context by combining protection motivation theory (PMT) and usage situation theory. We test our hypotheses using data (n = 346) collected from a field survey based on a real scenario. The findings reveal that PMT and usage situation theory work well to explain passengers’ protective behavior during ride-sharing. This study explains the motivation behind passengers’ protective behavior in the ride-sharing context, extends the contents of PMT by exploring its antecedents, and extends the contents of usage situation theory by introducing a new dimension. Our findings can help ride-sharing platforms take appropriate strategies to improve passengers’ protective behavior.  相似文献

When information wanted to be free: Discursive bifurcation of information and the origins of Web 2.0     

Eran Fisher 《The Information Society》2018,34(1):40-48

In the 1990s the aphorism “information wants to be free” reigned supreme, limiting our thinking in consequential ways. In actuality this aphorism was a fragment of a much more nuanced statement by Steward Brand, who also talked about “information wants to be expensive.” It seemed for quite a while that there was no resolution to the contradiction: information as both free and expensive. Eventually Web 2.0 resolved this contradiction by providing an architecture where information could be both free and expensive. Web 2.0 was not a product of technological advances: social media, wikis, big data platforms, and so forth. It was borne out of the understanding that free information on media platforms could yield profitable data on users. This article lays bare the discursive moves through which this understanding came about.  相似文献   

CloudChain: A novel distribution model for digital products based on supply chain principles     

《International Journal of Information Management》2018

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed.  相似文献   

Smart cities: Advances in research—An information systems perspective     

《International Journal of Information Management》2019

Smart cities employ information and communication technologies to improve: the quality of life for its citizens, the local economy, transport, traffic management, environment, and interaction with government. Due to the relevance of smart cities (also referred using other related terms such as Digital City, Information City, Intelligent City, Knowledge-based City, Ubiquitous City, Wired City) to various stakeholders and the benefits and challenges associated with its implementation, the concept of smart cities has attracted significant attention from researchers within multiple fields, including information systems. This study provides a valuable synthesis of the relevant literature by analysing and discussing the key findings from existing research on issues related to smart cities from an Information Systems perspective. The research analysed and discussed in this study focuses on number of aspects of smart cities: smart mobility, smart living, smart environment, smart citizens, smart government, and smart architecture as well as related technologies and concepts. The discussion also focusses on the alignment of smart cities with the UN sustainable development goals. This comprehensive review offers critical insight to the key underlying research themes within smart cities, highlighting the limitations of current developments and potential future directions.  相似文献   

The geography of school choice in a city with growing inequality: the case of Vancouver     

Ee-Seul Yoon  Christopher Lubienski  Jin Lee 《教育政策杂志》2018,33(2):279-298

This analysis aims to measure the impact of school choice policy on secondary school students’ enrolment patterns within the social geography of Vancouver, an increasingly polarized global city. The rationale for the study is to examine the impact of ‘education market’ reforms on the socio-economic composition of schools in a Canadian context, where a social welfare commitment to educational equality is being replaced by market-oriented policies and increasing social inequality. Our study is guided by Bourdieu’s theory of site in considering whether growing inequality and polarization of wealth in a city are correlated with the ways families choose schools. We apply a geographical methodology (Geographic Information System) to delineate spatial patterns of choosing schools. Our analysis shows that those who opt out of the under-subscribed schools come from the neighborhoods with relatively higher capital than those who remain in their assigned schools. Also, those who opt into the over-subscribed schools in the affluent areas come from the neighborhoods with above-average levels of capital in Vancouver. Overall, we find that the spatial inequality in school choice generally follows the uneven distribution of capital/wealth across the city. The pattern of student mobility indicates an increasing level of segregation.  相似文献   

Modes of learning and profitability in Colombian and Mexican SMEs     

Luis Enrique Valdez-Juárez  Omar Javier Solano-Rodríguez  Dominique Philippe Martin 《The Journal of High Technology Management Research》2018,29(2):193-203

The aim of this study is to analyze the effects of different modes of learning on innovation and profitability in SMEs in two Latin American countries; Mexico and Colombia. The data were obtained using a sample of 250 companies in the industrial sector operating in both countries. Results show that an integrated mode of learning based on internal and external knowledge supported by technological infrastructure have positive and significant effects on the degree of innovation and the profitability in SMEs However this effect appears to be not significantly different from the traditional SMEs mode of learning based mainly on market orientation.  相似文献

知识产权对象与客体的界定长期无法达成一致,对知识产权法学的体系化具有不利影响。从传统民事权利对象的界定方法来看,知识产权的对象就是知识和信息,是有价值、可再现并与现有知识、信息相区别的知识和信息,具体包括作品、专利技术方案、商标以及其他未公开的信息。结合权利的本质可知,知识产权的客体就是利用这些知识信息所生之利益。权利客体的财产性和权利对象的独特性,是知识产权成为独立一类民事权利的二元依据。  相似文献   

Synergetic governing controller design for the hydraulic turbine governing system with complex conduit system     

Jianzhong Zhou  Yuncheng Zhang  Yang Zheng  Yanhe Xu 《Journal of The Franklin Institute》2018,355(10):4131-4146

The hydraulic turbine governing system plays an indispensable role in maintaining the stability of electrical power system. In this paper, synergetic control theory is introduced to enhance the regulating ability of the hydraulic turbine governing system. For the purpose of describing the characteristics of objective system and deducing the synergetic control rule, a nonlinear mathematic model of a hydraulic turbine governing system with long tail race and two surge tanks is established. Furthermore, the nonlinear characteristic of the hydraulic turbine is described by six variable partial derivatives. For further investigation, the hydraulic turbine governing system is conducted to running under load condition when its coaxial generator connects to an infinite bus. Simulation experiments have been made under both load disturbance and three-phase short circuit fault conditions to compare the dynamic performances of proposed synergetic governing controller and classic PID controller. The results indicate that the proposed synergetic governing controller is an effective alternative in normal condition and a superior one in emergency. Moreover, the robustness of synergetic governing controller has also been discussed at the end of this paper.  相似文献
