This collection of ten critical essays is the first scholarly criticism of haiku by Sonia Sanchez, who has exemplified herself for six decades as a major figure in the Black Arts Movement, a central activist in civil rights and women's movements, and an internationally-known writer in American literature. Sanchez's haiku, as an integral and prominent part of contemporary African American poetry, have expressed not only her ideas of nature, beauty, and harmony but also her aesthetic experience of music, culture, and love. Aesthetically, this experience reflects a poetic mind which has helped the poet to shape or reimage her poetic spirit.

It has long been suspected, and recently confirmed, that there is an etiologic relationship between several viruses and naturally occurring neoplasias. Virus precursors in the form of nucleic acids or antigens have consistently been associated with certain neoplasias. However, the role of these virus-specified precursors in etiology remains obscure. Recent studies of virus-associated neo plasias have led to advances in molecular techniques, which have yielded increas ingly sensitive assays for detection of virus-specific nucleic acids, and which have enabled the disruption of virus particles without concomitant loss in antigenicity of the components. These procedures have, in turn, resulted in molecular probes that allow more definitive evaluation of the host response to its virus and to the tumor cell with which the virus or its precursors are associated. Evaluations of the immune response and status of the host have provided important informa tion about carcinogenesis and the tools for seroepidemiological studies of a variety of cancers. These seroepidemiological studies have demonstrated that several human cancers, e. g., Burkitt's lymphoma and nasopharyngeal carcinoma, are probably virus-induced, and that antibodies that are diagnostic and prog nostic for these diseases are detectable. The conclusion that feline leukemia is a disease transmitted horizontally by a virus resulted primarily from immunologi cal experiments."

For courses in management science and decision modeling. Quantitative Analysis for Management helps students to develop a real-world understanding of business analytics, quantitative methods, and management science by emphasising model building, tangible examples, and computer applications. The authors offer an accessible introduction to mathematical models and then students apply those models using step-by-step, how-to instructions. For more intricate mathematical procedures, the 13th Edition offers a flexible approach, allowing instructors to omit specific sections without interrupting the flow of the material. Supporting computer software enables instructors to focus on the managerial problems and solutions, rather than spending valuable class time on the details of algorithms.
