The 10 essays here explore the images of blacks in historical contemporary American culture. Negative and stereotypical images of blacks have been deeply embedded in our art, music, literature, film, theater, and other forms of expression. On the other hand, as the preface states, black artists and others have also celebrated `images of strength, beauty, and achievement.' Reflecting the complexity of the relationship between the races, these two elements are often intertwined. This reference work explores these images, both positive and negative, and their historical development and impact on both black and American culture. . . . Its unique qualities are the discussions and sources for stud...
Providing a unique overview to wheat and related species, this book comprises the proceedings of the 7th International Wheat Conference, held in Mar del Plata, Argentina, at the end of 2005. Leading scientists from all over the world, specialized in different areas that contribute to the better understanding of wheat production and use, review the present achievements and discuss the future challenges for the wheat crop.
Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultim...
Casper Branner (ca.1729-ca.1792) emigrated from southern Germany or possibly eastern Switzerland, and settled in the Shenandoah Valley of Virginia probably about 1750.
