Higher education institutions (HEIs) around the world are engaged in internationalisation efforts. Yet internationalisation per se is associated with significant pressures on the environment and environmental resources, which need to be addressed. This study aims to assess the opportunities, benefits and challenges associated with the internationalisation of universities at a global level.

A total of 27 relevant case studies were extracted from the literature to illustrate how HEIs worldwide are ensuring sustainability in their internationalisation efforts.

Through case studies of international HEIs, the study lists the opportunities, benefits and challenges associated with the internationalisation of universities at a global level and some of the measures that may be deployed to reduce the environmental impacts of their international activities.

This study provides a welcome contribution to the literature because it outlines some of the works taking place at universities, where matters related to sustainable development are considered against a background of internationalisation efforts.

In light of the growing emphasis on sustainability in higher education, this paper aims to explore the effectiveness of sustainability university rankings, specifically focusing on sustainable development (SD), to understand their impact on advancing universities’ sustainability goals and address gaps in practical implications and limitations.

This study examines sustainability rankings in higher education (HE) through document analysis. Chosen for significance, these rankings were evaluated for regional participation, criteria and the top 20 universities. The method involved scrutinising official ranking websites for diverse perspectives on sustainability. The results are classified into three categories: regional participation, assessment criteria and top universities in the latest iterations.

The findings show that sustainability rankings are widely spread, and their existence has led to an increased motivation for universities to further engage in efforts in the field of SD. This study offers suggestions for optimising the role of promoting SD principles and practices in HE.

This comprehensive assessment sheds light on rankings’ operations and success levels. It makes a significant contribution to the literature, providing an unprecedented overview of analysed rankings and on sustainability assessment and their impact. This analysis will be valuable for universities towards the integration of SD principles and practices into the HE environment.

Emergent leadership is a relatively new phenomenon, suggesting that leaders emerge from within teams without having a formal leadership assigned role. While emergent leadership has much relevance in today's organizations transitioning from vertical to horizontal leadership, there is a paucity of research about the process of emergent leadership that enables team members to become influential within teams.

Using purposive sampling, we interview 40 individuals in nine agile teams working in five Information Technology firms.

We identify various traits, experiences, behaviors, skills, and abilities of emergent leaders. Broadly, we conclude that an emergent leader serves as a “detail-oriented structure” or a “big picture coordinator.” Based on the findings, we propose a leadership emergence process that details how team members gain status and emerge as leaders, as well as the factors that can cause them to lose that status and return to becoming a regular team member. Furthermore, we introduce a model that demonstrates how technical expertise and personality traits interact, influencing team dynamics and facilitating the emergence of leaders within a team.

We contribute to the literature on emergent leadership by conceptualizing lateral influence and a leadership emergence process. We also extend the agile leadership literature and address some calls for empirical studies to understand the leadership dynamics in agile teams. We also show some limitations of the existing approaches and offer some useful insights.
