There are prevailing paradoxes which must be resolved if we are to advance an educational system worthy of 21st century citizens. A paradox is an apparently contradictory statement which may be true however great the contradiction. Somehow, we have to resolve these contradictions if we are to move forward. “We assume that all can learn, but all do not learn at the same pace and in the same way. Yet, we want everyone to complete schooling at the same time or be judged a failure” (Indiana University Dean of Education, Howard Mehlinger, Retired). During the advent years of the July 4th 2026 Birthday Celebration of The Declaration of Independence, the paradoxes blocking our democratic institutions of learning have not been resolved. The Institute for 21st Century Learning has used in the preparation of LEARN OR DIE a community of national scholars, each having their own insights, yet the knowledge and skill attributes necessary for addressing today’s paradox barriers: Qualitative Action Research; The New Global Economy; The New Urbanism; The New University; Complex Systems Evaluation; 21st Century Leadership; Vision-Based Community Development; and Citizens’ Community Connections and the Transformation of Community Schools. Is the American Revolution still alive?
Community foundations bring together the resources of individuals, families, and businesses to support effective nonprofits in their communities. Over the years, foundations have come to engage community problem-solving through more than just grant-making. They have added a rich array of other activities, including programs of community capacity building, active modes of advocacy, and centres for meeting. In 2011, the 700+ institutions in the United States gave an estimated $4.2 billion to a variety of nonprofit activities in fields that included the arts and education, health and human services, the environment, and disaster relief. The origins of this book stem from conversations among the leadership of community foundations about the challenges they must overcome in order to make such "foundational" contributions to their communities. As community foundations enter the second century of their existence (the first foundation was formed in Cleveland in 1914), the need for knowledge and best practices has never been greater. This book, with expert authors representing the best and the brightest in this important field, fills that need.
The 1970 and 1994 editions of The Black Librarian in America by E.J. Josey singled out racism as an important issue to be addressed within the library profession. Although much has changed since then, this latest collection of 48 essays by Black librarians and library supporters again identifies racism as one of many challenges of the new century. Essays are written by library educators, library graduate students, retired librarians, public library trustees, veteran librarians, and new librarians fresh out of school with great ideas and wholesome energies. They cover such topics as poorly equipped school libraries and the need to preserve the school library, a call to action to all librarians to make the shift to new and innovative models of public education, the advancement in information technology and library operations, special libraries, recruitment and the Indiana State Library program, racism in the history of library and information science, and challenges that have plagued librarianship for decades. This collection of poignant essays covers a multiplicity of concerns for the 21st-century Black librarian and embodies compassion and respect for the provision of information, an act that defines librarianship. The essays are personable, inspiring, and thought provoking for all library professionals, regardless of race, class, or gender.

Criminology has experienced tremendous growth over the last few decades, evident, in part, by the widespread popularity and increased enrollment in criminology and criminal justice departments at the undergraduate and graduate levels across the U.S. and internationally. Evolutionary paradigmatic shift has accompanied this surge in definitional, disciplinary and pragmatic terms. Though long identified as a leading sociological specialty area, criminology has emerged as a stand-alone discipline in its own right, one that continues to grow and is clearly here to stay. Criminology, today, remains inherently theoretical but is also far more applied in focus and thus more connected to the academic and practitioner concerns of criminal justice and related professional service fields. Contemporary criminology is also increasingly interdisciplinary and thus features a broad variety of ideological orientations to and perspectives on the causes, effects and responses to crime. 21st Century Criminology: A Reference Handbook provides straightforward and definitive overviews of 100 key topics comprising traditional criminology and its modern outgrowths. The individual chapters have been designed to serve as a "first-look" reference source for most criminological inquires. Both connected to the sociological origins of criminology (i.e., theory and research methods) and the justice systems′ response to crime and related social problems, as well as coverage of major crime types, this two-volume set offers a comprehensive overview of the current state of criminology. From student term papers and masters theses to researchers commencing literature reviews, 21st Century Criminology is a ready source from which to quickly access authoritative knowledge on a range of key issues and topics central to contemporary criminology. This two-volume set in the SAGE 21st Century Reference Series is intended to provide undergraduate majors with an authoritative reference source that will serve their research needs with more detailed information than encyclopedia entries but not so much jargon, detail, or density as a journal article or research handbook chapter. 100 entries or "mini-chapters" highlight the most important topics, issues, questions, and debates any student obtaining a degree in this field ought to have mastered for effectiveness in the 21st century. Curricular-driven, chapters provide students with initial footholds on topics of interest in researching term papers, in preparing for GREs, in consulting to determine directions to take in pursuing a senior thesis, graduate degree, career, etc. Comprehensive in coverage, major sections include The Discipline of Criminology, Correlates of Crime, Theories of Crime & Justice, Measurement & Research, Types of Crime, and Crime & the Justice System. The contributor group is comprised of well-known figures and emerging young scholars who provide authoritative overviews coupled with insightful discussion that will quickly familiarize researchers, students, and general readers alike with fundamental and detailed information for each topic. Uniform chapter structure makes it easy for students to locate key information, with most chapters following a format of Introduction, Theory, Methods, Applications, Comparison, Future Directions, Summary, Bibliography & Suggestions for Further Reading, and Cross References. Availability in print and electronic formats provides students with convenient, easy access wherever they may be.
