Researchers piloted a problem-based learning (PBL) activity in a master’s degree-granting strategic studies program to explore how students apply knowledge and skills learned from the curriculum to their formulation of a strategy addressing a real-world global security scenario.

This mixed-methods pilot study used ethnographic observation, participant feedback, document analysis and surveys to assess the learning and engagement of multinational postgraduate students in the context of a PBL environment.

Findings revealed gaps in students’ causal logic and literacy, as well as student discomfort with ambiguity and reliance upon heuristic frameworks over willingness to conduct substantive, current and relevant research. Additionally, observed group dynamics represented a lack of inclusive collaboration in mixed gender and multinational teams. These findings suggest foundational issues with the curriculum, teaching methodologies and evaluation practices of the studied institution.

This study highlights the need to include explicit instruction in problem-solving and causal literacy (i.e. logical reasoning) in postgraduate programs for national and global security professionals, as well as authentic opportunities for those students to practice interpersonal communication.

This study aims to investigate the impact of viewing different types of digital environment images on college students’ positive emotions, nature relatedness and environmental preference. This aimed to address the gap in empirical studies regarding the effects of digital environment images on these psychological constructs.

This study used a three-group experimental between-subjects design. Participants (48 undergraduate students) were divided into three groups, each viewing a different set of digital images (nature, city or object). Pre- and posttest measures assessed positive emotions and nature relatedness, whereas environmental preference was measured after image viewing. One-way analysis of variance and post hoc Tukey’s honestly significant difference (HSD) tests were used to analyze the data.

Viewing digital nature images elicited significantly higher positive emotions, nature relatedness and environmental preference compared to viewing city or object images. In addition, environmental preference for the digital object group was marginally higher than the city group.

This study was limited by its relatively small sample size. Although further research is needed to investigate the underlying mechanisms behind the observed effects, this study provides valuable implications for education, economic dimensions and public policy initiatives, encouraging the development of pro-environmental attitudes and behaviors.

The findings suggest that incorporating digital nature images into learning activities can promote positive emotions, nature relatedness and environmental preference among college students. This has implications for the design of digital learning environments, especially for those with limited access to natural environments.

By promoting positive emotions and nature relatedness, digital nature experiences can contribute to emotional well-being and potentially foster pro-environmental behaviors. This can have implications for promoting sustainable lifestyles and environmental conservation efforts.

This study provides original empirical evidence on the impact of viewing digital environment images on several psychological constructs. It highlights the potential of digital nature experiences as a complement to direct nature exposure, particularly for those with limited access to natural environments. These findings contribute to the growing body of literature on the benefits of digital nature experiences and have implications for various fields, including education, environmental psychology and human–computer interaction.

This study aims to synthesize existing findings in the gig worker training literature and identify the training rationales adopted by these studies, using a synthesized framework of organizational training rationales. This study seeks to delineate the rationales behind gig worker training and highlight unaddressed training needs within digital platforms, ultimately proposing a research agenda for future studies in this area.

A systematic review methodology is adopted to synthesize and analyze empirical, peer-reviewed studies on gig worker training.

The systematic review reveals that competency and economic rationales are predominantly adopted in gig worker training studies, with the relationship rationale, common in traditional training, notably absent. This study also outlines seven future research directions to highlight identified challenges and unaddressed training needs.

To the best of the author’s knowledge, this study is the first work that systematically reviews existing findings on gig worker training.

Citizen engagement plays a crucial role in transitioning to sustainable service ecosystems. While customer engagement has been extensively studied in service research, citizen engagement has received significantly less attention. By synthesizing customer and citizen engagement literatures, this study develops an integrated framework to conceptually clarify the dual role of customer-citizen engagement for sustainability.

This study builds on a systematic literature review of customer engagement literature in service research and citizen engagement literature. Following a theory synthesis approach, we qualitatively analyzed 126 articles to develop an integrated conceptual framework of customer-citizen engagement for sustainability through a process of abductive reasoning.

The analysis showed that customer engagement and citizen engagement literatures have developed mostly separately but provide complementary views. While the customer engagement literature has traditionally focused on business-related facets, such as engagement with brands, the citizen perspective broadens the engagement scope to other citizens, communities and society in general. The integrated framework highlights the interplay between citizen and customer roles and the impact of their relationships with multiple objects on sustainability.

This integrated framework contributes to advancing our understanding of customer-citizen engagement, broadening the scope of subject-object engagement by examining the interplay between these roles in how they engage for sustainability and moving beyond the traditional dyadic perspective to a multi-level perspective of service ecosystems. This framework also enables the development of a set of research directions to advance the understanding of engagement in sustainable service ecosystems.
