Discusses the history, people, and culture of this island commonwealth and the life-style and problems of the Puerto Ricans who have migrated to the mainland in search of jobs.

The book Theory and Practice of Contrast completes, corrects and integrates the foundations of science and humanities, which include: theory of art, philosophy (aesthetics, epistemology, ontology, axiology), cognitive science, theory of information, theory of complexity and physics. Through the integration of these distant disciplines, many unresolved issues in contemporary science have been clarified or better understood, among others: defining impact (contrast) and using this definition in different fields of knowledge; understanding what beauty/art is and what our aesthetic preferences depend on; deeper understanding of what complexity and information are in essence, and providing their general definitions. Complexity means integration, value and goodness - concepts that seem to be neglected today. The book also has a high degree of integration/complexity, although each chapter introduces a new issue. The last chapter: "Binary Model of the Universe" draws attention to the need for including in physics the analysis of our mind and the resulting new possibilities, which include the mentioned (digital) model of the universe. Despite the difficult issues raised here, this study is written in accessible language and may be interesting not only for scientists and academics.

Contrasts are statistical procedures for asking focused questions of data. Compared to diffuse or omnibus questions, focused questions are characterized by greater conceptual clarity and greater statistical power when examining those focused questions. If an effect truly exists, we are more likely to discover it and to believe it to be real when asking focused questions rather than omnibus ones. Researchers, teachers of research methods and graduate students will be familiar with the principles and procedures of contrast analysis, but will also be introduced to a series of newly developed concepts, measures, and indices that permit a wider and more useful application of contrast analysis. This volume takes on this new approach by introducing a family of correlational effect size estimates.

Writer and artist Margie Crisp has traveled the length of Texas’ Colorado River, which rises in Dawson County, south of Lubbock, and flows 860 miles southeast across the state to its mouth on the Gulf of Mexico at Matagorda Bay. Echoing the truth of Heraclitus’s ancient dictum, the river’s character changes dramatically from its dusty headwaters on the High Plains to its meandering presence on the coastal prairie. The Colorado is the longest river with both its source and its mouth in Texas, and its water, from beginning to end, provides for the state’s agricultural, municipal, and recreational needs. As Crisp notes, the Colorado River is perhaps most frequently associated with its middle reaches in the Hill Country, where it has been dammed to create the six reservoirs known as the Highland Lakes. Following Crisp as she explores the river, sometimes with her fisherman husband, readers meet the river’s denizens—animal, plant, and human—and learn something about the natural history, the politics, and those who influence the fate of the river and the water it carries. Those who live intimately with the natural landscape inevitably formulate emotional responses to their surroundings, and the people living on or near the Colorado River are no exception. Crisp’s own loving tribute to the river and its inhabitants is enhanced by the exquisite art she has created for this book. Her photographs and maps round out the useful and beautiful accompaniments to this thoughtful portrait of one of Texas’ most beloved rivers.
