Puerto Ricans maintain a vibrant identity that bridges two very different places--the island of Puerto Rico and the U.S. mainland. Whether they live on the island, in the States, or divide time between the two, most imagine Puerto Rico as a separate nation and view themselves primarily as Puerto Rican. At the same time, Puerto Ricans have been U.S. citizens since 1917, and Puerto Rico has been a U.S. commonwealth since 1952. Jorge Duany uses previously untapped primary sources to bring new insights to questions of Puerto Rican identity, nationalism, and migration. Drawing a distinction between political and cultural nationalism, Duany argues that the Puerto Rican "nation" must be understood ...
This volume updates the original scientific survey of Puerto Rico and the US Virgin Islands, which was begun by the New York Academy of Sciences in 1913. Many aspects of natural history - geology, paleobotany, plant ecology, herpetology, ornithology, insect taxonomy, archaeology - are covered. Each paper provides a brief historical survey and a mention of future research opportunities in the field.
In this study, hardwood sawing technology was identified in five tropical countries: Ghana, Brazil, Venezuela, Indonesia, and Malaysia. The density of wood and presence of silica make it a challenge to saw many tropical hardwoods. The bandsaw is the most commonly used machine and is employed in many sizes and configurations. Sawblade parameters and operating procedures vary according to the nature of the species being sawn and are influenced as much by local custom as technical knowledge of the process. The most commonly reported problems include poor saw maintenance, lack of trained personnel, obsolete equipment, and inadequate sawtooth geometry and wear resistance. Some problems can be addressed by technology transfer, others must be addressed by research.

Medicine has long framed race relations in the Caribbean-that basin where African and European cultures have met from the beginning of the Colonial Period to the twentieth century. Whether Sir Hans Sloane, founder of the British Museum and President of the Royal Society of London, who as a physician wrote about African medical beliefs and practices, or Dr. Leonard Wood, military physician who served as military governor to Cuba, medicine and its practitioners have played a key role in the perception of the African Other. The book is a collection of essays treating the subject from various points of views. While it may perhaps not surprise the reader that colonial physicians often failed to acknowledge the same failings in their own Western medicine as that criticized of African practices, the medical view found later in the period lacked that biting racism of an earlier era.
