We are entering a new era—an era of impact. The largest intergenerational transfer of wealth in history will soon be under way, bringing with it the potential for huge increases in philanthropic funding. Engine of Impact shows how nonprofits can apply the principles of strategic leadership to attract greater financial support and leverage that funding to maximum effect. As Good to Great author Jim Collins writes in his foreword, this book offers "a detailed roadmap of disciplined thought and action for turning a good nonprofit into one that can achieve great impact at scale." William F. Meehan III and Kim Starkey Jonker identify seven essential components of strategic leadership that set high-achieving organizations apart from the rest of the nonprofit sector. Together, these components form an "engine of impact"—a system that organizations must build, tune, and fuel if they hope to make a real difference in the world. Drawing on decades of teaching, advising, grantmaking, and research, Meehan and Jonker provide an actionable guide that executives, staff, board members, and donors can use to jumpstart their own performance and to achieve extraordinary results for their organization. Along with setting forth best practices using real-world examples, the authors outline common management challenges faced by nonprofits, showing how these challenges differ from those faced by for-profit businesses in important and often-overlooked ways. By offering crucial insights on the fundamentals of nonprofit management, this book will help leaders equip their organizations to fire on all cylinders and unleash the full potential of the nonprofit sector.

Search engines have become a key part of our everyday lives. Yet while much has been written about how to use search engines and how they can be improved, there has been comparatively little exploration of what the social and cultural effects might be. Like all technologies, search engines exist within a larger political, cultural, and economic environment. This volume aims to redress this balance and to address crucial questions such as: * How have search engines changed the way we organize our thoughts about the world, and how we work? * What are the ‘search engine wars', what do they portend for the future of search, and who wins or loses? * To what extent does political control of search engines, or the political influence of search engines, affect how they are used, misused, and regulated? * Does the search engine help shape our identities and interactions with others, and what implications does this have for privacy? Informed members of the information society must understand the social contexts in which search engines have been developed, what that development says about us as a society, and the role of the search engine in the global information environment. This book provides the perfect starting point.

The Challenge Built to Last, the defining management study of the nineties, showed how great companies triumph over time and how long-term sustained performance can be engineered into the DNA of an enterprise from the verybeginning. But what about the company that is not born with great DNA? How can good companies, mediocre companies, even bad companies achieve enduring greatness? The Study For years, this question preyed on the mind of Jim Collins. Are there companies that defy gravity and convert long-term mediocrity or worse into long-term superiority? And if so, what are the universal distinguishing characteristics that cause a company to go from good to great? The Standards Using tough benchmarks, Collins and his research team identified a set of elite companies that made the leap to great results and sustained those results for at least fifteen years. How great? After the leap, the good-to-great companies generated cumulative stock returns that beat the general stock market by an average of seven times in fifteen years, better than twice the results delivered by a composite index of the world's greatest companies, including Coca-Cola, Intel, General Electric, and Merck. The Comparisons The research team contrasted the good-to-great companies with a carefully selected set of comparison companies that failed to make the leap from good to great. What was different? Why did one set of companies become truly great performers while the other set remained only good? Over five years, the team analyzed the histories of all twenty-eight companies in the study. After sifting through mountains of data and thousands of pages of interviews, Collins and his crew discovered the key determinants of greatness -- why some companies make the leap and others don't. The Findings The findings of the Good to Great study will surprise many readers and shed light on virtually every area of management strategy and practice. The findings include: Level 5 Leaders: The research team was shocked to discover the type of leadership required to achieve greatness. The Hedgehog Concept (Simplicity within the Three Circles): To go from good to great requires transcending the curse of competence. A Culture of Discipline: When you combine a culture of discipline with an ethic of entrepreneurship, you get the magical alchemy of great results. Technology Accelerators: Good-to-great companies think differently about the role of technology. The Flywheel and the Doom Loop: Those who launch radical change programs and wrenching restructurings will almost certainly fail to make the leap. “Some of the key concepts discerned in the study,” comments Jim Collins, "fly in the face of our modern business culture and will, quite frankly, upset some people.” Perhaps, but who can afford to ignore these findings?

Bearing Chambers in Aero-Engines are located near the rolling-element type of bearings which support the shafts and accomodate the resulting thrust loads. One of the main task of the bearing chambers is, beside an efficient scavenging of the lubricating oil, the cooling of the hot compartments. A very complex two-phase air-oil flow takes usually place in these bearing chambers consisting of oil droplet-laden air flows and shear-driven liquid wall films. The interaction of the droplets with the wall films is significantly influencing the wall heat transfer and the cooling performance of these systems. For this reason, a detailed characterization and modelling of the mass and momentum exchange between droplets and wall films for the unique impingement parameter range in bearing chambers is inevitable. This scientific report investigates the oil droplet impact dynamics for typical impingement regimes relevant to aero-engine bearing chambers. The application of a Direct Numerical Simulation (DNS) technique based on the Volume-of-Fluid (VOF) method and coupled with a gradient-based adaptive mesh refinement (AMR) technique allowed to characterize the drop impact dynamics during various single micro- and millimeter drop impacts onto thin and thick films. With the help of a special numerical treatment, a self-perturbing mechanism is installed that leads to the correct resolution of the crown disintegration process. The numerical methodology was thoroughly validated using the experimental results of millimeter sized drop impacts onto deep liquid pools. These results were developed with an enhanced back-illuminated high-speed imaging and Particle Tracking Velocimetry (PTV) technique. New insights into the cavity penetration, the crown's breakup dynamics and the secondary droplet characteristics following a single drop impact have been developed with the help of the isolated variation of different parameters of influence. Particularly the influence of the Froude number, the impingement angle, and the cavity-wall interaction delivered results to date not reported in scientific literature. Beside the advances in fundamental physics describing the drop impact dynamics with the help of the numerical and experimental results, a set of correlations could also be derived. From these correlations, a drop-film interaction model was formulated that is suitable for the parameter range found in bearing chambers.
