The concept of multiculturalism has been widely integrated into popular culture over the last half century. Yet the standard multicultural constructs - such as race, gender, sexual orientation, and religion - while still essential, are no longer adequate in today's increasingly globalised world. This book broadens the concept of multiculturalism to encompass internationalism. In other words, it internationalises multiculturalism. It argues that professionals in all fields can enhance both their multicultural and international competence to perform more effectively. The contributors review the relevant research and, drawing also from personal experience, apply these concepts to real-world professional practice in business, mental health, and education - three areas that are especially well positioned to impact the health and well-being of clients, employees, and customers. This book will appeal to scholars of multiculturalism as well as practicing professionals in a range of fields, especially business, mental health, and education.
