Passengers as defenders: unveiling the role of customer-company identification in the trust-customer citizenship behaviour relationship within ride-hailing context
No full textRide-hailing platforms such as Didi, Uber, and Lyft have changed the travel industry. Promoting the passengers' trust in platform and customer citizenship behaviour (CCB) is both challenging and important. This study employed a mixed-methods design, consisting of 21 interviews and 351 online surveys, to develop and examine the trust-CCB model in the ride-hailing context. Our findings reveal that platforms can foster passengers' trust by sending service-related signals (i.e., service quality and structure assurance) and a firm-related signal (i.e., platform reputation). Customer-company identification (CCI) mediates the relationship between passengers' trust and CCB, where passengers engage in CCB by providing recommendations, exhibiting forgiving behaviour, providing feedback, and participating in research in ride-hailing. Additionally, firm-related signals, including platform size and reputation, enhance the positive relationship between trust and CCI. These findings contribute to the body of knowledge on trust, CCB, and signaling theory, providing potential practical implications for ride-hailing platforms.</p
Designing a talents training model for cross-border e-commerce: a mixed approach of problem-based learning with social media
No full text© 2019, Springer Science+Business Media, LLC, part of Springer Nature. Cross-border e-commerce has developed rapidly integrating the global economy. Research has presented some solutions for the challenges and barriers in cross-border e-commerce from the perspective of the enterprise. However, little is known about the requirements of cross-border e-commerce talents and how to train them. In this paper, we firstly conducted semi-structured interviews to acquire the requirements of cross-border e-commerce talents. Business and market knowledge, technical skills, analytical ability and business practical ability were found to be the four core requirements. Then, we integrated problem-based learning and social media to design a talents training model for cross-border e-commerce and did a program to evaluate effectiveness of the model. Finally, its effectiveness was evaluated from the four evaluation dimensions of attitude, perceived enjoyment, concentration and work intention. The talents training model was improved according to the suggestions
Achieving employees’ agile response in e-governance: exploring the synergy of technology and group collaboration
No full textThe transformation of technology and collaboration methods driven by the e-government system forces government employees to reconsider their daily workflow and collaboration with colleagues. Despite the extensive existing knowledge of technology usage and collaboration, there are limitations in explaining the synergy between technology usage and group collaboration in achieving agile response from the perspective of government employees, particularly in the e-government setting. To address these challenges, this study provides a holistic understanding of the successful pathway to agile response in e-governance from the perspective of government employees. This study explores a dual path to achieve agile response in e-governance through qualitative analysis, involving 34 in-depth semi-structured interviews with government employees in several government sectors in China. By employing three rounds of coding processes and adopting Interpretative Structural Modeling (ISM), this study identifies the five-layer mechanisms leading to agile response in e-governance, considering both government employee technology usage and group collaboration perspectives. Findings of this study provides suggestions and implications for achieving agile response in e-governance.</p
Aerodynamic force breakdown based on vortex force theory
No full textA recently proposed aerodynamic force theory of compressible high Reynolds number flows based on the concept of vortex force is here analyzed. The aerodynamic force is obtained by means of volume and surface integrals within the flow. The theory proposes the decomposition of the aerodynamic force, both lift and drag components, in reversible and irreversible contri- butions. The former is responsible for the lift and lift induced drag, the latter for the profile and wave drag components. The analysis is here concentrated on the following aspects: a) sensitivity of the force decomposition to the choice of the integration domain, b) analysis in the limits of infinite Reynolds number. The verification of the analysis is obtained post-processing inviscid and viscous numerical solutions around airfoils and wings

Relating Research and Teaching: comparing experiences and beliefs
No full textThe relationship between research and teaching has possible benefits and inherent tensions. It is a recurrent topic of discussion by faculty including engineering educators. Exploring a potentially beneficial relationship and is of interest and possible value to engineering faculty, our students, and our stakeholders. Institutions and departments have developed a range of approaches including research-led, research informed, or just plain scholarly. This paper examines the relationship between research and teaching in the undergraduate curriculum. It compares and contrasts evidence of the beliefs and experiences of the engineering faculty and the engineering student. It presents and analyses the result of surveys which gathered qualitative and qualitative data to explore the inter-relationship of research and teaching; in the curriculum; and as it is delivered and experienced in the lab, seminar room and lecture hall. This research builds on existing work developed in a preliminary study which examined ways in which synergies between research and teaching could be achieved, particularly in the ‘hard/applied’ areas of the curriculum. It analyses data from the ‘research-intensive’ and the ‘teaching-intensive’ perspective

No full textEducation for Cataloging in Spanish Universities: A Descriptive and Critical Study
No full textObjective: This is a critical descriptive study of the situation of cataloging as an academic discipline within Library and Information Science studies in Spain. Material and methods: The descriptive analysis of the sectional contents of the general and specific guidelines of the degrees of Diplomado (three-year degree) and Licenciado (fiveyear degree) in LIS and the curricular programs of the Spanish university schools or departments. Variables analyzed: The denomination and content descriptors of the course offerings and credit hours. The test-retest method was used, with a qualitative processing of data. Results: General data is given about the studies in LIS: their introduction, the universities that offer them, and the degrees awarded. Cataloging is considered an obligatory core subject matter, and is represented by several courses that present important differences insofar as their denominations, their credits, and their character from one curricular program to the next. The average credit requisite for obligatory courses in cataloging in Spain is 14 (1 credit = 10 class hours), and 19.7 if electives are also considered. At present, this discipline is undergoing a reform that will produce important changes as a result of the adaptation of university studies to the common framework of the European Union
Introduction to Energy-Efficient Train Operation
No full textRailway, as one of the most energy-efficient transport, plays an essential role in improving the world’s energy and environmental sustainability. Statistics about rail share of transport activities and the corresponding energy consumption will demonstrate the energy efficiency of railway and indicate the potential of developing railway transport. Therefore, this chapter will provide an overview of the railway's energy consumption and traffic volume shares. Statistics presented in this chapter show that railway energy consumption decreased in these decades while its transport volume kept stable, and the traffic volume share of the railway is extremely large in urban transport. To achieve the goal of carbon neutralization, the European Union and many countries have conducted research projects on railway energy conservation. The technologies developed in these projects include energy-efficient train driving, integrated timetabling, using regenerative braking energy, etc. A summary of these technologies is also given, along with their potential energy savings, which range from 1 to 25%. This book will analyse and illustrate the whole systems processes of train operation with optimisation solutions. The structure of the following chapters will be presented at the end.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin
