The collaborative filtering algorithm is a classical and widely used approach in product recommendation systems. However, the existing algorithms rely mostly on common ratings of items and do not consider temporal information about items or user interests. To solve this problem, this study proposes a new user-item composite filtering (UICF) recommendation framework by leveraging temporal semantics.

The UICF framework fully utilizes the time information of item ratings for measuring the similarity of items and takes into account the short-term and long-term interest decay for computing users’ latest interest degrees. For an item to be probably recommended to a user, the interest degrees of the user on all the historically rated items are weighted by their similarities with the item to be recommended and then added up to predict the recommendation degree.

Comprehensive experiments on the MovieLens and KuaiRec datasets for user movie recommendation were conducted to evaluate the performance of the proposed UICF framework. Experimental results show that the UICF outperformed three well-known recommendation algorithms Item-Based Collaborative Filtering (IBCF), User-Based Collaborative Filtering (UBCF) and User-Popularity Composite Filtering (UPCF) in the root mean square error (RMSE), mean absolute error (MAE) and F1 metrics, especially yielding an average decrease of 11.9% in MAE.

A UICF recommendation framework is proposed that combines a time-aware item similarity model and a time-wise user interest degree model. It overcomes the limitations of common rating items and utilizes temporal information in item ratings and user interests effectively, resulting in more accurate and personalized recommendations.

To enhance the understanding of the antecedents of students' career adaptability, this study employs the crossover model to explore the potential transfer of career adaptability from headteachers to students and the underlying mechanisms involved.

This study examined the proposed moderated mediation model using matched survey data collected from 37 headteachers and 1,598 students in Chinese higher vocational colleges.

Headteachers’ career adaptability is positively related to students’ career adaptability via students’ psychological capital. An increased frequency of headteacher–student interactions strengthened the indirect relationship between headteachers' career adaptability and students' career adaptability.

The findings suggest that, under certain conditions, headteachers’ career adaptability could be transferred to students via students’ psychological capital.

Considering the important role of knowledge management in the global growth of world economies, the importance of knowledge management in the tourism industry can hardly be overestimated. Knowledge management, empowering leadership and innovation can open new research prospects for online travel and tourism, thereby increasing organizational capacity. In this context, this study aims to investigate the relationship between knowledge management practices and transformational leadership, along with the mediating role in this relationship of leadership communication. Knowledge management practices are discussed through the lens of managers’/organizational perspectives working in the online travel and tourism industry.

Using a descriptive research method, the data were collected from a total of 174 managers/senior executives working in the online travel and tourism sectors. The proposed conceptual framework was evaluated using structural equation modeling through AMOS 21 and Process Macro (SPSS-Plugin).

The results revealed a significant increase in the adoption of knowledge management practices in the online travel and tourism sector under transformative leadership. The results also highlighted that effective communication is a vital contributor and significant complementary mediator in the relationship between transformative leadership and knowledge management practices.

The results of this study suggest that transformational leaders, who are equipped with the “high touch” nature of leadership and the “high tech” aspect of the contemporary workplace, are the best fit to manage online travel and tourism organizations. To have an adequate knowledge management system, knowledge managers should adopt a transformative leadership style and receive comprehensive training in developing leadership abilities such as effective communication competencies.

To the best of the authors’ knowledge, this study is the first to demonstrate that, in emerging online travel and tourism sectors, organizational knowledge can be managed through effective leadership communication.

Drawing on social cognitive career theory (SCCT), this study aims to examine how university students’ attitude towards entrepreneurship education (ATEE) consists of affective, cognitive and behavioral components influences their entrepreneurial intentions. It further examines the role of entrepreneurial self-efficacy (ESE) as a mediator and social norms as a moderator in the ATEE – entrepreneurial intentions and – ESE relationships, respectively.

A sample of 428 university students from the new generational cohort entering workforce now (i.e. generation Z) from the four main cities of the province of Punjab, Pakistan, were considered using an online administered questionnaire. The study analyzes data using SPSS v25 and AMOS v22 and presents descriptive statistics, reliability, validity analysis and linear regression analysis. Furthermore, to test mediation and moderation hypotheses, Hayes’ PROCESS macro v3.0 was used.

The results confirm that individuals’ ATEE based on affective, cognitive and behavioral components have significant influence on entrepreneurial intentions. The findings also confirm the strong mediating role of ESE between the components of ATEE and entrepreneurial intentions. Furthermore, the conditional effects results confirm that social norms strengthened the positive relationships between the affective, behavioral and cognitive components of ATEE – ESE at three levels (low, medium and high).

This study is the first of its nature to unlock the missing link between ATEE’s components and entrepreneurial intentions using the theoretical foundations of SCCT. Furthermore, this study provides theoretical and practical implications specifically considering a developing country – Pakistan.
