The outcome of speciation is put to the test in regions where incipient species' ranges overlap and hybrid offspring are produced, known as hybrid zones. Delineating the parental species that contributed each part of a hybrid genome, the ancestry, can provide insights into the history of hybrid individuals and the progression of speciation between these lineages. The genomic locations where regions of different ancestry meet are called junctions. Junctions are historical recombination events that occurred in hybrids, and thus are records of the history of the zone in which they are found. In this dissertation, I explore the effect of demography on junctions and then investigate junctions in a classic hybrid zone. I find that junctions are very responsive to demographic history, particularly the age of the hybrid zone, the population size, and the rate of migration within a stepping-stone model. I also find that population substructure uniquely impacts ancestry in a way that is not captured by single population models. I also introduce a novel metric to describe the sharing of junctions between individuals-the junction frequency spectrum. I then review my attempt to integrate the junction frequency spectrum and other metrics of ancestry into an inference method using approximate Bayesian computation. My approach is unable to accurately estimate parameters, but I outline suggestions that might allow this inference to be successful in the future. Finally, I identify hundreds of thousands of junctions in mice from two populations within the European house mouse hybrid zone between Mus musculus domesticus and M. m. musculus. I show that these junctions are variable between chromosomes and across the genome. I present the first estimates of the junction frequency spectrum in a hybrid population. The populations that I survey show unique patterns of ancestry and junction sharing, indicating that they have distinct histories. I use junctions along with the site frequency spectrum to infer the age of the hybrid zone as a few thousand years. Finally, I identify several regions of the genome that are outliers for ancestry metrics as candidate regions for incompatibilities between M. m. musculus and M. m. domesticus.

This book brings together contributions from scholars from Europe and the United States to honor the theological work of Antje Jackelén, the first female Archbishop of the Church of Sweden. In Archbishop Antje Jackelén’s installation homily, she identifies the strength of the Church as a “global network of prayer threads.” This book is an honorary and celebratory volume providing a “global network of prayerful essays” by contributors from a variety of academic disciplines to creatively engage, reflect, and illuminate the theological work of Archbishop Jackelén. Prior to her tenure in the Church of Sweden as Bishop of the Diocese of Lund and now the Archbishop of the Church of Sweden, Jackelén served as professor of Systematic Theology, Director of the Zygon Center and President of European Society for the Study of Science and Religion (ESSSAT). While each essay intentionally embraces the theological and ministerial work of Jackelén during her academic tenure, they also venture into areas as diverse as climate change, media studies, human uniqueness, hermeneutics, time, ethics, Christian theological tradition and history, traumatology, politics and society. As the first diverse explication of the theological thinking of Archbishop Jackelén by her theological colleagues, this text provides scholars with an expansion of the scope of Archbishop Jackelén’s theological thinking and initiates laity into the impact of Jackelén thinking that combines with grace and precision the traditions of the Church, the challenges and gifts of the sciences, and the needs and longings of society and the world.

WHAT IS CASSANDRA'S TEAR? The epic story of an artist's dreams of preserving the beauty of the human spirit and to capture love and peace forever within Cassandra's Tear. The CASSANDRA'S TEAR Trilogy spills over with imagery and metaphor to create a rare portrait of who and what we humans really are. A rare insight into a primitive terrorist world of fantasy made real by current events. In Book One ECHO OF A SCREAM the Portrait of Cassandra sheds a tear for the victimization of women. In Book Two ECHO OF A VOICE The Artist Eve paints the portrait, the scientist Jonathan Morro discovers Cassandra's Tear is not human! A stone with strange markings leads to a blind Cassandra and the mysterious tribe of the Taiowa. An impossible love creates the birth of the first interspecies child Ashanti. Will the secret of the stones prove the existence of a FALLEN GOD intent on IT's goal...to return to space? Cassandra's Tear transforms from the Echo of A Scream of creation into the Echo of A Voice that speaks to all of us through imagination!

Distinguished scholar and library systems innovator Frederick Kilgour tells a five-thousand-year story in this exciting work, a tale beginning with the invention of writing and concluding with the emerging electronic book. Calling on a lifetime of interest in the growth of information technology, Kilgour brings a fresh approach to the history of the book, emphasizing in rich, authoritative detail the successive technological advances that allowed the book to keep pace with ever-increasing needs for information. Borrowing a concept from evolutionary theory--the notion of punctuated equilibria--to structure his account, Kilgour investigates the book's three discrete historical forms--the clay tablet, papyrus roll, and codex--before turning to a fourth, still evolving form, the cyber book, a version promising swift electronic delivery of information in text, sound, and motion to anyone at any time. The clay tablet, initially employed as a content descriptor for sacks of grain, proved inadequate to the growing need for commercial and administrative records. Its successor the papyrus roll was itself succeeded by the codex, a format whose superior utility and information capacity led to sweeping changes in the management of accumulated knowledge, the pursuit of learning, and the promulgation of religion. Kilgour throughout considers closely both technological change and the role this change played in cultural transformation. His fascinating account of the modern book, from Gutenberg's invention of cast-type printing five hundred years ago to the arrival of books displayed on a computer screen, spotlights the inventors, engineers, and entrepreneurs who in creating the machinery of production and dissemination enabled the book to maintain its unique cultural power over time. Deft, provocative, and accessibly written, The Evolution of the Book will captivate book lovers as well as those interested in bibliographic history, the history of writing, and the history of technology.
