Many free-floating bicycle-sharing (FFBS) operators in cold region cities will put bicycles in warehouses and suspend services in winter due to factors such as safety and maintenance costs, resulting in the corresponding travel demand no longer be met. Considering the short-distance and green travel characteristics of FFBS, the flexible bus, as a sustainable demand-responsive transit service, is a suitable alternative transportation mode. To operate such a flexible bus system, service area and operation time planning is a key stage, however, the planning methods in relevant studies are not suitable for this research scenario. In view of the above, this paper proposed a data-driven method to determine the service area and operation time of flexible buses based on FFBS data. Firstly, an FFBS trip path reconstruction algorithm consists of fine-grained road network modelling and trajectory matching is proposed. Then, in the defined time slice, incorporating the idea of ride-sharing routes generation, according to the densitybased clustering principle and considering topology between trajectories, a path clustering algorithm PATHSCAN is developed to generate the one-day path clusters. After that, a frequent pattern mining algorithm is applied to the multiday path clusters, and frequent pattern results with spatio-temporal correlation will be merged into the final service area. The generated planning results will cover ride-matching trips and high-frequency riding paths. Detailed application analysis and verification are carried out by using the real data from Tianjin, China. Through the evaluation and verification under the relatively limited experimental data set, the proposed data-driven method shows ideal planning results. Flexible bus service can supplement the green short-distance travel mode after the suspension of FFBS and can avoid FFBS travel demands switched to unsustainable transportation modes to a large extent. This study will contribute to urban sustainable transportation development and improving greenness....
In view of the problem that the transaction privacy in the current blockchain technology service is easy to be leaked, a bulletproof alliance chain technology service transaction privacy protection mechanism is proposed. Firstly, this paper uses digital certificates as access mechanisms and stores them on the chain to ensure that the identity of technical service transactions is trusted. Secondly, the transaction data of the technical service user is hidden in the Pedersen commitment, and the Bulletproof is used to build the scope proof. Enable the verifier to conduct confidential verification of the legitimacy of the transaction without obtaining the sensitive information of the transaction, so as to ensure that the user’s transaction privacy is not disclosed. Finally, the security and privacy of the proposed privacy protection scheme are analyzed, and the comparison with other zero-knowledge proof schemes shows that the scheme has the advantages of strong privacy, scalability, and low storage cost....
Under the background of rural revitalization strategy, the key of rural education revitalization lies in the construction of rural teachers, and the key of rural teacher team construction lies in the professional development of teachers. Based on the SWOT-PEST model, from the micro and macro perspective, combined with the current politics, economy, society, technology analyzes the internal advantages and disadvantages, and external opportunities and threats, which adheres to the principle of “play advantages, overcome disadvantages”, from strengthening school-based research, relying education informatization, building teacher education community, choosing the best and matching the school administrators putting forward the corresponding SO strategy, ST strategy, WO strategy and WT strategy....
Tourism experience is a genuine source of destination attractiveness and long-lasting competitive advantage. Understanding the main drivers of the tourist experience in destinations is a critical step toward managing and delivering a satisfying destination experience to tourists. However, amidst a stream of research that explores experiences in different service settings, a framework of destination experience remains underexplored. To fill this gap in research, this article aims to draw an integrated conceptual framework of what makes a tourist experience in destinations along the travel journey and depicts the antecedents and consequences. By doing so, DMOs and other tourism stakeholders can fit their marketing strategies to cater to tourists’ needs and preferences. Also, this article discusses several measures and emerging research methods to capture the components of the destination experience....
The importance and necessity of the activity of incubators in the university environment and the creation of start-ups play an important role: in the formation of entrepreneurial skills and their involvement in various activities for both teachers and students and in the knowledge-based economy. The purpose of the study is to evaluate the impact of business incubators located in universities on the development of students´ and teaching staff´s entrepreneurial skills and competences. To achieve the goal, the questionnaire was developed for the teaching staff of higher education institutions, who work within the faculties with orientation in the following general fields of study: economic sciences, social and behavioral sciences, educational sciences, etc. The questionnaire was built using the complex method, which includes the questioning and observation. Likewise, the case study method was used, which allowed us to reflect the real and concrete situation within the studied university and the aspects mentioned in the research are not reflected in specialized literature. The analysis of the results of the survey of teachers in higher education regarding the perception of the creation of university incubators and the entrepreneurial skills of students within universities, and the needs of the activity of the university incubator in the framework of entrepreneurial education in order to train the skills and competencies of future entrepreneurs and those mentioned in the study determined the economic-social impact by concluding and emphasizing some important aspects to restore both the economic situation and to involve the teaching staff in the formation and activity of the Entrepreneurial University through the innovation incubator and their support....
