''Nobody does it better. Spillane and Diamond expose the myths of distributed leadership on a topic beset with confusion. They lead us through the... conceptual minefield with pristine clarity and the authority that comes from deeply grounded knowledge of life in real schools and classrooms.'' -- John MacBeath, Chair of Educational Leadership, University of Cambridge''Spillane and Diamond, in the best of research traditions, add to their conception of distributed leadership. Studying real practice enriches their work immeasurably. A must-read for leaders and those who study them!'' -- Ann Lieberman, Senior Scholar, Carnegie Foundation for the Advancement of TeachingDistributed leadership has become an important term for educational policymakers, practitioners, and researchers in the United States and around the world, but there is much diversity in how the term is understood. Some use it as a synonym for democratic or participative leadership. This book examines what it means to take a distributed perspective based on extensive research and a rich theoretical perspective developed by experts in the field.

James Spillane, the leading expert in Distributed Leadership, shows how leadership happens in everyday practices in schools, through formal routines and... informal interactions. He examines the distribution of leadership among administrators, specialists, and teachers in the school, and explains the ways in which leadership practice is stretched over leaders, followers, and aspects of the situation, including routines and tools of various sorts in the organization such as memos, scheduling procedures, and evaluation protocols.This book is a volume in the Jossey-Bass Leadership Library in Education—a series designed to meet the demand for new ideas and insights about leadership in schools.

Updated to reflect the latest changes and advances in the field, Distribution System Modeling and Analysis, Third Edition again illustrates methods that... will ensure the most accurate possible results in computational modeling for electric power distribution systems. With the same simplified approach of previous editions, this book clearly explains the principles and mathematics behind system models, also discussing the "smart grid" concept and its special benefits. However, this volume adds a crucial element not found in previous editions. The first two books developed models for all components but focused less on how to actually implement those models on a computer for planning and for real-time analysis. This book includes numerous models of components and several practical examples, to demonstrate how engineers can apply and customize computer programs to help them plan and operate systems. It also covers approximation methods to help users interpret computer program feedback, so they recognize when a result is not what it should be. Another improvement is the book’s earlier introduction (in chapter 4) of the modified ladder iterative technique. The author explains the need for this method—which is used in most distribution analysis programs—detailing how it is applied and why it is among the most powerful options. Concluding with a detailed summary of presented topics that readers have come to expect, this edition provides useful problems, references, and assignments that help users apply Mathcad® and WIndmil programs to put their new learning into practice. An invaluable tool for engineering students and professionals worldwide, this book explores cutting-edge advances in modeling, simulation, and analysis of distribution systems that can ensure the continued dispersal of safe, reliable energy.

District Leadership That Works begins by expunging the myth that district leadership and high-level school administrators are useless and deter... educational progress. Rather, it shows how district leaders can unite a school district through establishing common goals that will improve overall student achievement, while maintaining teachers stylistic freedom. The authors introduce the concept of a top-down power mechanism called defined autonomy. Rather than decentralizing authority, defined autonomy puts the focus on district-defined non-negotiable goals and a system of accountability supported by assessment tools. With district-defined goals and assessment tools, schools can successfully address student achievement and respond more quickly and effectively to student failure. The authors then delve into setting and monitoring non-negotiable goals for achievement and instruction, both at the district and school levels. When setting goals for achievement, they suggest, leaders must look past typical standardized testing and create formative assessment tools that add more variables to measurement. Leaders should focus on programs that monitor the progress of failing students and on processes for taking action. Regarding non-negotiable goals for instruction, the authors suggest that focusing only on teacher certification and subject-matter expertise is insufficient for school improvement; rather, goals should be set and actions monitored for improving teachers instructional skills as well. Attainment of these skills can then be measured by the progress of student achievement using assessment tools. District Leadership That Works goes on to assure educators that district leadership is not a unilateral decision-making process; rather, leadership involves schools, teacher unions, students, and community members in collaborative goal-setting. Leaders must also ensure that the school board is accountable for appropriately allocating resources to support these goals; school board decisions regarding expenditures and resource allocation directly impact student achievement levels. Defined autonomy does not mean self-determination; school must follow non-negotiable goals. The authors outline the inter-relationship between the two levels how district goals impact school instruction and policies. They acknowledge the challenges of second-order change to transform schools, since this involves a mental and procedural break with past educational paradigms. They explain how district leaders can tactfully and successfully deal with any resistance to the changes and the new role that district leadership must play. In the final analysis, the authors argue, the ultimate goal of stronger district leadership and non-negotiable goal-setting is student achievement, since that is why educational systems exist in the first place.

How should we understand biblical texts where God is depicted as acting irrationally, violently, or destructively? If we distance ourselves from... disturbing portrayals of God, how should we understand the authority of Scripture? How does the often wrathful God portrayed in the Old Testament relate to the God of love proclaimed in the New Testament? Is that contrast even accurate?Disturbing Divine Behavior addresses these perennially vexing questions for the student of the Bible. Eric A. Seibert calls for an engaged and discerning reading of the Old Testament that distinguishes the particular literary and theological goals achieved through narrative characterizations of God from the rich understanding of the divine to which the Old Testament as a whole points. Providing illuminating reflections on theological reading as well, this book will be a welcome resource for any readers who puzzle over disturbing representations of God in the Bible.

Disturbing the Peace tells the story of a controversial Cajun priest, a former gung-ho Navy officer injured in a bomb blast in Vietnam, who has... tirelessly championed human rights and aroused the conscience of a nation. The fast-paced historical biography also profiles the movement he founded to close a notorious U.S. Army school whose graduates have committed atrocities across Latin America. The journey of this "spiritual hobo" has more twists and turns than the Mississippi River: from love affairs that ended in heartbreak to patriotic impulses that ended in disillusionment. From dreams of wealth to missionary work among the poor. From protests and prison terms to a cloistered monastery. From confrontations with church hierarchy to political battles on Capitol Hill. Bourgeois’ opposition to militarism began after a blind Vietnamese orphan opened his eyes to the realities of war. Since then, his human rights work has taken him to half a dozen war-torn countries: To Bolivia, where U.S.-backed security forces kidnapped him after he spoke out against torture. To El Salvador, where he disappeared and two of his friends were killed by U.S.-trained death squads. To Nicaragua and Honduras, where the CIA was helping contra commandos overthrow a government. To Colombia, where he witnessed the human toll of the drug war, escorted by an Army general linked to terrorist bombings. To Iraq, where he met with desperately poor Iraqis just before the country became a bloodbath. The assassinations of six Jesuit priests in El Salvador in 1989 spurred Bourgeois to investigate the U.S. Army’s School of the Americas, then a little known training installation whose graduates were later linked not only to the Jesuit massacre, but to gross human rights abuses throughout Latin America. The latter half of the book profiles the movement he founded to close the school; the Congressional battles over its funding; the Pentagon’s forced admission that the school used manuals advocating torture and assassination; and the courage of average Americans – including WWII and Vietnam veterans, students, union workers, professionals, clergy and elderly nuns – who have risked imprisonment each year at the annual November demonstration at Fort Benning, Ga., where the school is located. In documenting the sordid record of the school’s graduates – from dictators and intelligence agents to death squad leaders and torturers, Disturbing the Peace shines a light on the dark side of U.S. foreign policy – not only in Latin America, but in Iraq, where Bush administration policies on torture led to the disgrace of Abu Ghraib. While the Pentagon closed and then re-opened the school under a new name -- the Western Hemisphere Institute for Security Cooperation, the SOA Watch movement has remained one of the strongest voices of dissent since Sept.11, 2001, winning court battles that have helped safeguard First Amendment rights at a time civil liberties are eroding. Time and again throughout the struggle, Bourgeois, along with his fellow provocateurs for justice, lend credence to Margaret Mead’s belief "that a small group of committed citizens can change the world."
