Leadership emerges as a dominant theme with five articles examining different dimensions: the role of leadership in improving organizational citizenship behavior and teacher performance in vocational high schools; transformational leadership's influence on change management in virtual teams mediated by organizational culture; ethical leadership and knowledge sharing effects on employee performance mediated by higher college commitment; leadership style influence on work motivation and employee performance at a regional revenue agency; and transformational leadership's effect on team performance in construction projects.

Marketing and consumer behavior are addressed in three articles: online shopping decisions based on perceived ease of use as mediation; marketing mix strategy influence on supermarket customer satisfaction in Banyuwangi; and digital marketing strategy in the online fashion industry. Strategic management perspectives are represented by research on international market development strategy in companies and a financial performance analysis of Misool Baseftin Foundation, which doubled its performance over five years.

Social impact and entrepreneurship are explored through two articles: welfare transformation through productive business empowerment at Khadijah 2 Orphanage Surabaya, and the effect of entrepreneurship education on entrepreneurial intentions with entrepreneurial motivation and opportunity recognition as intervening variables.
