Meat Makes People Powerful
From large-scale cattle farming to water pollution, meat— more than any other food—has had an enormous impact on our environment. Historically, Americans have been among the most avid meat-eaters in the world, but long before that meat was not even considered a key ingredient in most civilizations’ diets. Labor historian Wilson Warren, who has studied the meat industry for more than a decade, provides this global history of meat to help us understand how it entered the daily diet, and at what costs and benefits to society. Spanning from the nineteenth century to current and future trends, Warren walks us through the economic theory of food, the discovery of protein, the Japanese eugeni...
Morphogenesis in Plant Tissue Cultures
! Morphogenesis, or developmental morphology, is a dynamic process! and a fascinating field of investigation. Since the beginning of this century plant morphologists (Eames, 1961), anatomists (Eames and Macdaniels, 1947) and embryologists (Maheshwari, 1950) have studied the processes of development and differentiation by observing whole plants and their histological preparations and have generated a wealth of information on the structural changes associated with various developmental stages in the life cycle of a large number of plant species. Around 1940 plant morphogenesis became an experimental field when plant physiologists initiated studies on the effect of treatments, such as application of physiologically active compounds or growth regulators, irradiation, exposure to different day length, temperature and injury, on morphological and structural changes. During the past two decades geneticists and molecular biologists have become interested in plant morphogenesis and extensive work is being done to understand the regulation of gene expression during morphogenesis and how the products of genetic information control the developmental processess.
The Vascular Cambium
The cambium has been variously defined as follows: "The actively dividing layer of cells that lies between, and gives rise to, secondary xylem and phloem (vascular cambium)" (IAWA 1964); "A meristem with products of periclinal divisions commonly contributed in two directions and arranged in radial files. Term pre ferably applied only to the two lateral meristems, the vascular cambium and cork cambium, or phellogen" (Esau 1977); and, "Lateral meristem in vascular plants which produces secondary xylem, secondary phloem, and parenchyma, usually in radial rows; it consists of one layer of initials and their undifferentiated deriva tives" (Little and Jones 1980). Clearly, the cambium is a diverse...
Tied to the Great Packing Machine
Ambitious in its historical scope and its broad range of topics, Tied to the Great Packing Machine tells the dramatic story of meatpacking’s enormous effects on the economics, culture, and environment of the Midwest over the past century and a half. Wilson Warren situates the history of the industry in both its urban and its rural settings—moving from the huge stockyards of Chicago and Kansas City to today’s smaller meatpacking communities—and thus presents a complete portrayal of meatpacking’s place within the larger agro-industrial landscape. Writing from the vantage point of twenty-five years of extensive research, Warren analyzes the evolution of the packing industry from its e...
