Identity is defined in many different ways in various disciplines in the social sciences and sub-disciplines within psychology. The developmental psychological approach to identity is characterized by a focus on developing a sense of the self that is temporally continuous and unified across the different life spaces that individuals inhabit. Erikson proposed that the task of adolescence and young adulthood was to define the self by answering the question: Who Am I? There have been many advances in theory and research on identity development since Erikson's writing over fifty years ago, and the time has come to consolidate our knowledge and set an agenda for future research. The Oxford Handbook of Identity Development represents a turning point in the field of identity development research. Various, and disparate, groups of researchers are brought together to debate, extend, and apply Erikson's theory to contemporary problems and empirical issues. The result is a comprehensive and state-of-the-art examination of identity development that pushes the field in provocative new directions. Scholars of identity development, adolescent and adult development, and related fields, as well as graduate students, advanced undergraduates, and practitioners will find this to be an innovative, unique, and exciting look at identity development.

Conceived as the meanings that individuals attach to their selves, a substantial stockpile of theory related to identities accumulated across the arts, social sciences, and humanities over many decades continues to nourish contemporary research on self-identities in organizations. In times which are more reflexive, narcissistic, and fluid, the identities of participants in organizations are increasingly less fixed and less certain, making identity issues both more salient and more interesting. Particular attention has been given to processes of identity construction, often styled 'identity work'. Research has focused on how, why, and when such processes occur, and their implications for organizing and individual, group, and organizational outcomes. This has resulted in a burgeoning stream of research from discursive, dramaturgical, symbolic, socio-cognitive, and psychodynamic perspectives that most often casts individuals' efforts to fabricate identities as intentional, relational, and consequential. Seemingly intractable debates centred on the nature of identities - their relative stability or fluidity, whether they are best regarded as coherent or fractured, positive (or not), and how they are fabricated within relations of power - combined with other conceptual issues continue to invigorate the field. However, these debates have also led to some scepticism regarding the future potential of identities research. Yet as the chapters in this Handbook demonstrate, there are considerable grounds for optimism that identity, as root metaphor, nexus concept, and means to bridge levels of analysis has significant potential to generate multiple compelling streams of theorizing in organization and management studies.

Fifteen years ago, Jeffrey Jensen Arnett proposed emerging adulthood as a new life stage at ages 18-29, one distinct from both the adolescence that precedes it and the young adulthood that eventually follows. Rather than marrying and becoming parents in their early 20s, most people in developed countries now postpone these transitions until at least their late 20s, spending these years in self-focused explorations as they try out different possibilities in their education, careers, and relationships. Since Arnett proposed his theory of emerging adulthood in 2000, it has turned into a full-fledged academic field, and the ideas have been applied in practical areas as well, such as mental health and education. The Oxford Handbook of Emerging Adulthood brings together for the first time the wealth of theory and research that has developed in this new and burgeoning field. It includes chapters by many prominent scholars on a wide range of topics, such as brain development, relations with friends, relations with parents, expectations for marriage, sexual relationships, media use, substance use and abuse, and resilience. The chapters both summarize the existing research and point the way to new prospects for research in the years to come.

The topic of organizational identity has been fast growing in management and organization studies in the last 20 years. Identity studies focus on how organizations define themselves and what they stand for in relation to both internal and external stakeholders. Organizational identity (OI) scholars study both how such self-definitions emerge and develop, as well as their implications for OI, leadership and change, among others. We believe there are at least four inter-related reasons for the growing importance of OI. OI addresses essential questions of social existence by asking: Who are we and who are we becoming as a collective? It is a relational construct connecting concepts and ideas that are often viewed as oppositional, such as "us" and "them" or "similar" and "differen." OI is also nexus concept serving to gather multiple central constructs, also represented in this Handbook. Finally, OI is inherently useful, as knowing who you are is the foundation for being able to state what you stand for and what you are promising to others, no matter their relation with the organization. The Handbook provides a road-map to the OI field organized in over 25 chapters across seven sections. Each chapter not only offers a broad overview of its particular topic, each also advances new knowledge and discusses the future of research in its area of focus.

Multiculturalism is a prevalent worldwide societal phenomenon. Aspects of our modern life, such as migration, economic globalization, multicultural policies, and cross-border travel and communication have made intercultural contacts inevitable. High numbers of multicultural individuals (23-43% of the population by some estimates) can be found in many nations where migration has been strong (e.g., Australia, U.S., Western Europe, Singapore) or where there is a history of colonization (e.g., Hong Kong). Many multicultural individuals are also ethnic and cultural minorities who are descendants of immigrants, majority individuals with extensive multicultural experiences, or people with culturally mixed families; all people for whom identification and/or involvement with multiple cultures is the norm. Despite the prevalence of multicultural identity and experiences, until the publication of this volume, there has not yet been a comprehensive review of scholarly research on the psychological underpinning of multiculturalism. The Oxford Handbook of Multicultural Identity fills this void. It reviews cutting-edge empirical and theoretical work on the psychology of multicultural identities and experiences. As a whole, the volume addresses some important basic issues, such as measurement of multicultural identity, links between multilingualism and multiculturalism, the social psychology of multiculturalism and globalization, as well as applied issues such as multiculturalism in counseling, education, policy, marketing and organizational science, to mention a few. This handbook will be useful for students, researchers, and teachers in cultural, social, personality, developmental, acculturation, and ethnic psychology. It can also be used as a source book in advanced undergraduate and graduate courses on identity and multiculturalism, and a reference for applied psychologists and researchers in the domains of education, management, and marketing.

The Oxford Handbook of Human Development and Culture provides a comprehensive synopsis of theory and research on human development, with every chapter drawing together findings from cultures around the world. This includes a focus on cultural diversity within nations, cultural change, and globalization. Expertly edited by Lene Arnett Jensen, the Handbook covers the entire lifespan from the prenatal period to old age. It delves deeply into topics such as the development of emotion, language, cognition, morality, creativity, and religion, as well as developmental contexts such as family, friends, civic institutions, school, media, and work. Written by an international group of eminent and cutting-edge experts, chapters showcase the burgeoning interdisciplinary approach to scholarship that bridges universal and cultural perspectives on human development. This "cultural-developmental approach" is a multifaceted, flexible, and dynamic way to conceptualize theory and research that is in step with the cultural and global realities of human development in the 21st century.

The Oxford Handbook of the Self explores a fascinating diversity of questions about our understanding of self from a variety of interdisciplinary perspectives, including philosophy, ethics, psychology, neuroscience, psychopathology, narrative, and postmodern theories.
