When starting a family history project, where do you begin? For me, the answer is simple: Genesis. Being a man, a man of science, I find that as I get older, science has proven more and more that the truth is very simple. In the opening statements of Genesis, God created the universe as we know it and also created the stars. How is such a thing possible? We are children of God. You know, children are like their creator, full of wonder. Wonder, why? Genesis states, In the beginning God created the heavens and the earth. The earth was without form and void and darkness was over the face of the deep. As we learn more on just how we got here, along comes a brilliant young scientist named Stephen Hawking. He explains in mathematical ways how the universe started with a big bang, started from nothing, and burst forth faster than the speed of light. Stars formed and gathered together to form galaxies then matter collected to form planets to circle around the stars. There was eternal darkness, and then there were the stars and light. As time passed, God planted the seeds of life. What is time? As we read the Bible, we were always in conflict with time. How do we feel comfortable with the evolution of life and the time frame of the Bible? Here, again, I find the answer is simple. Time, to us, is something we made up to understand what goes on around us; God is on his own time. I like to use baking an apple pie as my example of time and what it takes. Heres the question I ask, how long does it take to bake an apple pie? The answer I get is about an hour. I reply with Oh, you can? So here is my response to the one-hour apple pie: Where did the apple come from? How long did the apples take to grow? Where did that variety of apple come from? How long did it take for the seed to grow into a tree? How did you get the apple? At a store? How did the store get there? How did the refrigeration and transportation come to be? What about the cinnamon and sugar you used, where did it come from? (Cinnamon comes from Indiadried tree bark.) What about the tin used to make the pan used to bake the pie? When was electricity harnessed to be used by man, the modern stove?
One of humankind’s oldest companions, the hawthorn tree, is bound up in the memories of every recorded age and the plot lines of cultures all across the Northern Hemisphere. Hawthorn examines the little-recognized political, cultural, and natural history of this ancient spiky plant. Used for thousands of years in the impenetrable living fences that defined the landscapes of Europe, the hawthorn eventually helped feed the class antagonism that led to widespread social upheaval. In the American Midwest, hawthorn-inspired hedges on the prairies made nineteenth-century farming economically rewarding for the first time. Later, in Normandy, mazelike hedgerows bristling with these thorns nearly cost the Allies World War II. Bill Vaughn shines light on the full scope of the tree’s influence over human events. He also explores medicinal uses of the hawthorn, the use of its fruit in the world’s first wine, and the symbolic role its spikes and flowers played in pagan beliefs and Christian iconography. As entertaining as it is illuminating, this book is the first full appreciation of the hawthorn’s abundant connections with humanity.
When he quit a powerful secret society, Smith Donnell lost his fortune—and walked away from love. Beautiful heiress Arden Leigh deserved a man who could give her everything. Not a high-society outcast with nothing to his name and a bull's-eye on his back. But when Arden's curiosity made her the society's new target, Smith had to protect her—and win back her trust. Convincing Arden to let him back into her life would take a miracle. But Smith would do anything to keep her safe, even though he'd already sacrificed his heart—and this time, the price might be his life.
“For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.” –Randy Stafford, Architect At-Large, Oracle Coherence Product Development “This book is a must-read for anybody looking to put DDD into practice.” –Udi Dahan, Founder of NServiceBus Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations. Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment. The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals. Coverage includes Getting started the right way with DDD, so you can rapidly gain value from it Using DDD within diverse architectures, including Hexagonal, SOA, REST, CQRS, Event-Driven, and Fabric/Grid-Based Appropriately designing and applying Entities–and learning when to use Value Objects instead Mastering DDD’s powerful new Domain Events technique Designing Repositories for ORM, NoSQL, and other databases
USE THE ACTOR MODEL TO BUILD SIMPLER SYSTEMS WITH BETTER PERFORMANCE AND SCALABILITY Enterprise software development has been much more difficult and failure-prone than it needs to be. Now, veteran software engineer and author Vaughn Vernon offers an easier and more rewarding method to succeeding with Actor model. Reactive Messaging Patterns with the Actor Model shows how the reactive enterprise approach, Actor model, Scala, and Akka can help you overcome previous limits of performance and scalability, and skillfully address even the most challenging non-functional requirements. Reflecting his own cutting-edge work, Vernon shows architects and developers how to translate the longtime promises of Actor model into practical reality. First, he introduces the tenets of reactive software, and shows how the message-driven Actor model addresses all of them–making it possible to build systems that are more responsive, resilient, and elastic. Next, he presents a practical Scala bootstrap tutorial, a thorough introduction to Akka and Akka Cluster, and a full chapter on maximizing performance and scalability with Scala and Akka. Building on this foundation, you’ll learn to apply enterprise application and integration patterns to establish message channels and endpoints; efficiently construct, route, and transform messages; and build robust systems that are simpler and far more successful. Coverage Includes How reactive architecture replaces complexity with simplicity throughout the core, middle, and edges The characteristics of actors and actor systems, and how Akka makes them more powerful Building systems that perform at scale on one or many computing nodes Establishing channel mechanisms, and choosing appropriate channels for each application and integration challenge Constructing messages to clearly convey a sender’s intent in communicating with a receiver Implementing a Process Manager for your Domain-Driven Designs Decoupling a message’s source and destination, and integrating appropriate business logic into its router Understanding the transformations a message may experience in applications and integrations Implementing persistent actors using Event Sourcing and reactive views using CQRS Find unique online training on Domain-Driven Design, Scala, Akka, and other software craftsmanship topics using the for{comprehension} website at forcomprehension.com.
Luray Caverns, discovered in the quiet valley community of Luray in 1878, became the main attraction in Page County. In hopes of capitalizing on this new found Wonder of the World, executives of the Shenandoah Valley Railroad completed the rail from Hagerstown and Basic City to Luray by 1881. Mann Almond drove the final ceremonial spike just north of Defords Tannery in Luray. With the arrival of the railroad came a new economy supported by passengers, excursionists, lodging, and freight transport. The bulk of these transports were Eureka Mining Companys mineral extractions and Shenandoahs Big Gem iron bloom shipments. Lurays own Mercantile Mile leading to the caverns was laden with storehouses, offering goods found in larger cities, and the rail brought visitors in droves. The photographers who produced the images contained here did so only as a means of income, but today their work is our visual link to the past.
An important revisionist history that casts eighteenth-century British politics and imperial expansion in a new light In this bold debut work, historian James M. Vaughn challenges the scholarly consensus that British India and the Second Empire were founded in "a fit of absence of mind." He instead argues that the origins of the Raj and the largest empire of the modern world were rooted in political conflicts and movements in Britain. It was British conservatives who shaped the Second Empire into one of conquest and dominion, emphasizing the extraction of resources and the subjugation of colonial populations. Drawing on a wide array of sources, Vaughn shows how the East India Company was transformed from a corporation into an imperial power in the service of British political forces opposed to the rising radicalism of the period. The Company's dominion in Bengal, where it raised territorial revenue and maintained a large army, was an autocratic bulwark of Britain's established order. A major work of political and imperial history, this volume offers an important new understanding of the era and its global ramifications.
There is nothing certain in life except death. We are faced daily decisions, the ramifications of which permeate into every aspect of who we are and our success in life. From the moment we are turned upside down and slapped on our ‘behind’ until we take our last breath, uncertainty is with us. This is a story of that uncertainty and how it pertains to people’s lives. World War II took from Anne Bennett a husband and brother. She is left with three children to raise alone. She finds herself struggling with the depression and emptiness of living in the past without the ability to find her future. A decision is made. She will with her children return to her childhood home. ‘Clover View’ is a small farm outside Albion, Michigan owned by her parents. They too have struggled, with the loss of their only son, Bud. Maybe their return to her roots can help her children, her parents and herself put their loss behind them and fine hope for their future. There are problems with this plan as three generations collide while living under one roof. The story deals with understanding ourselves and respecting the needs of others. Regardless if the reader is a teen or a grandparent, this story has a message for everyone.
Tells the story of how the Episcopal Church gained influence over Alabama’s cultural, political, and economic arenas despite being a denominational minority in the state The consensus of southern historians is that, since the Second Great Awakening, evangelicalism has dominated the South. This is certainly true when one considers the extent to which southern culture is dominated by evangelical rhetoric and ideas. However, in Alabama one non-evangelical group has played a significant role in shaping the state’s history. J. Barry Vaughn explains that, although the Episcopal Church has always been a small fraction (around 1 percent) of Alabama’s population, an inordinately high proportion, close to 10 percent, of Alabama’s significant leaders have belonged to this denomination. Many of these leaders came to the Episcopal Church from other denominations because they were attracted to the church’s wide degree of doctrinal latitude and laissez-faire attitude toward human frailty. Vaughn argues that the church was able to attract many of the state’s governors, congressmen, and legislators by positioning itself as the church of conservative political elites in the state--the planters before the Civil War, the “Bourbons” after the Civil War, and the “Big Mules” during industrialization. He begins this narrative by explaining how Anglicanism came to Alabama and then highlights how Episcopal bishops and congregation members alike took active roles in key historic movements including the Civil War, Reconstruction, and the Civil Rights Movement. Bishops, Bourbons, and Big Mules closes with Vaughn’s own predictions about the fate of the Episcopal Church in twenty-first-century Alabama.
The Committee on Public Information, the major American propaganda agency during World War I, attracted a wide range of reform-oriented men and women who tried to generate enthusiasm for Wilson's international and domestic ideals. Vaughn shows that the CPI encouraged an imperial presidency, urged limits on free speech and called for an almost mystical attachment to the nation, but it also tried to present dispassionately the causes of American intervention in the war.

Vietnam Revisited shares the personal stories of America’s sons and daughters who fought the most unpopular war in our nation’s history. They answered America’s call to arms to fight the spread of communism in Southeast Asia. While antiwar sentiment and protests raged at home, many Americans volunteered to serve in the Vietnam War. Many were drafted. But the Vietnam veterans and Vietnam-era veterans put their lives on the line to do their nation’s bidding.
Winner of the 2022 Gustave O. Arlt Award in the Humanities, award by by the Council of Graduate Schools Explores the role of jazz celebrities like Ella Fitzgerald, Cab Calloway, Duke Ellington, and Mary Lou Williams as representatives of African American religion in the twentieth century Beginning in the 1920s, the Jazz Age propelled Black swing artists into national celebrity. Many took on the role of race representatives, and were able to leverage their popularity toward achieving social progress for other African Americans. In Lift Every Voice and Swing, Vaughn A. Booker argues that with the emergence of these popular jazz figures, who came from a culture shaped by Black Protestantism, religious authority for African Americans found a place and spokespeople outside of traditional Afro-Protestant institutions and religious life. Popular Black jazz professionals—such as Ella Fitzgerald, Cab Calloway, Duke Ellington, and Mary Lou Williams—inherited religious authority though they were not official religious leaders. Some of these artists put forward a religious culture in the mid-twentieth century by releasing religious recordings and putting on religious concerts, and their work came to be seen as integral to the Black religious ethos. Booker documents this transformative era in religious expression, in which jazz musicians embodied religious beliefs and practices that echoed and diverged from the predominant African American religious culture. He draws on the heretofore unexamined private religious writings of Duke Ellington and Mary Lou Williams, and showcases the careers of female jazz artists alongside those of men, expanding our understanding of African American religious expression and decentering the Black church as the sole concept for understanding Black Protestant religiosity. Featuring gorgeous prose and insightful research, Lift Every Voice and Swing will change the way we understand the connections between jazz music and faith.
As the world population grows and places more demand on limited fossil fuels, renewable energy becomes more relevant as part of the solution to the impending energy dilemma. Renewable energy is now included in national policies, with goals for it to be a significant percentage of generated energy within the coming decades. A comprehensive overview, Introduction to Renewable Energy explores how we can use the sun, wind, biomass, geothermal resources, and water to generate more sustainable energy. Taking a multidisciplinary approach, the book integrates economic, social, environmental, policy, and engineering issues related to renewable energy. It explains the fundamentals of energy, including the transfer of energy, as well as the limitations of natural resources. Starting with solar power, the text illustrates how energy from the sun is transferred and stored; used for heating, cooling, and lighting; collected and concentrated; and converted into electricity. A chapter describes residential power usage—including underground and off-grid homes—and houses that are designed to use energy more efficiently or to be completely self-sufficient. Other chapters cover wind power; bioenergy, including biofuel; and geothermal heat pumps; as well as hydro, tidal, and ocean energy. Describing storage as a billion-dollar idea, the book discusses the challenges of storing energy and gives an overview of technologies from flywheels to batteries. It also examines institutional issues such as environmental regulations, incentives, infrastructure, and social costs and benefits. Emphasizing the concept of life-cycle cost, the book analyzes the costs associated with different sources of energy. With recommendations for further reading, formulas, case studies, and extensive use of figures and diagrams, this textbook is suitable for undergraduates in Renewable Energy courses as well as for non-specialists seeking an introduction to renewable energy. Pedagogical Features: End-of-chapter problems Numerous case studies More than 150 figures and illustrations A solutions manual is available upon qualifying course adoption
Annotation This study presents an analysis of US-Iranian relations in the twentieth century, with particular attention to the crisis over nationalization of British oil interests at midcentury. As such, it focuses on the career of Muhammad Musaddiq, who struggled during those years to free his country from foreign influence, and whose memory continued to haunt bilateral relations with the United States up to the Iranian revolution. Throughout, it examines Anglo-American views of Iranians (and by implication of other non-Westerners) which affected - and still affect - the conduct of international relations.
Schools for All provides the first in-depth study of black education in Southern public schools and universities during the twelve-year Reconstruction period which followed the Civil War. In the antebellum South, the teaching of African Americans was sporadic and usually in contravention to state laws. During the war, Northern religious and philanthropic organizations initiated efforts to educate slaves. The army, and later the Freedmen's Bureau, became actively involved in freed-men's education. By 1870, however, a shortage of funds for the work forced the bureau to cease its work, at which time the states took over control of the African American schools. In an extensive study of records from the period, William Preston Vaughn traces the development—the successes as well as the failures—of the early attempts of the states to promote education for African Americans and in some instances to establish integration. While public schools in the South were not an innovation of Reconstruction, their revitalization and provision to both races were among the most important achievements of the period, despite the pressure from whites in most areas which forced the establishment of segregated education. Despite the ultimate failure to establish an integrated public school system anywhere in the South, many positive achievements were attained. Although the idealism of the political Reconstructionists fell short of its immediate goals in the realm of public education, precedents were established for integrated schools, and the constitutional revisions achieved through the Fourteenth and Fifteenth amendments laid the groundwork for subsequent successful assaults on segregated education.
This is the historical epic of James and Robert Paschal, two black brothers from McDuffie County and Atlanta, Georgia. These two stalwart men of color, fighting against the debilitating odds of a sharecropping life, became millionaires, philanthropists, world-renowned restaurant/hotel owners, and leaders in the struggle for civil rights." -- from book.

In rare photographs, the book reveals the history of the people and places of Lurary and Page County. Formed out of necessity in 1831, Page County had a great need to operate within its own boundaries of the Massanutten and Blue Ridge Mountains. A very unique situation arose when this rural area was coupled with the discovery in 1878 of something as spectacular as the Luray Caverns. Along with this new fame followed a large influx of tourists, industry, and varied commerce into the entire county from the lifeline created by the formation of the Shenandoah Valley Railroad in 1881. During the reconstruction years after the Civil War, and with the formation of "land and improvement" companies throughout the United States, Page County, along with the rest of the country, was booming. In fact, this unbridled growth was happening much too fast for this newly reformed country. This in turn brought about a severe recession in the 1890s that affected everyone, including the people of Page, no matter how secure they may have seemed with their new attraction.

Here, for the first time in more than eighty years, is a detailed study of political Antimasonry on the national, state, and local levels, based on a survey of existing sources. The Antimasonic party, whose avowed goal was the destruction of the Masonic Lodge and other secret societies, was the first influential third party in the United States and introduced the device of the national presidential nominating convention in 1831. Vaughn focuses on the celebrated "Morgan Affair" of 1826, the alleged murder of a former Mason who exposed the fraternity's secrets. Thurlow Weed quickly transformed the crusading spirit aroused by this incident into an anti-Jackson party in New York. From New York, the party soon spread through the Northeast. To achieve success, the Antimasons in most states had to form alliances with the major parties, thus becoming the "flexible minority." After William Wirt's defeat by Andrew Jackson in the election of 1832, the party waned. Where it had been strong, Antimasonry became a reform-minded, anti-Clay faction of the new Whig party and helped to secure the presidential nominations of William Henry Harrison in 1836 and 1840. Vaughn concludes that although in many ways the Antimasonic Crusade was finally beneficial to the Masons, it was not until the 1850s that the fraternity regained its strength and influence.
