Sleep and wakefulness undergo important changes with age. Awakening, a crucial event in the sleep-wake rhythm, is a transition implying complex physiological mechanisms. Its involvement in sleep disturbances is also well known. This collective volume is the first attempt to systematically approach awakening across development.A methodological section considers criteria to define awakening in a developmental perspective. Theoretical considerations on development of wakefulness and on its relation to consciousness are included and provide a vigorous impulse to go beyond present criteria and classifications. Age changes are the core of studies on development: a section of the book examines old ...
Southwestern piñon-juniper and juniper woodlands cover large areas of Arizona, New Mexico, Utah, and adjacent Colorado. Ponderosa pine forests are the most common timberland in the Southwest. All three ecosystems provide a variety of natural resources and economic benefits to the region. There are different perceptions of desired conditions. Public and private land managers have adapted research results and their observations and experiences to manage these ecosystems for multiresource benefits. Ways to mitigate the threat of wildfires is a major management issue for these ecosystems, and the wide-spread piñon mortality related to drought and the bark beetle infestation has heightened conc...

High blood pressure (BP) (with fats and smoking) is one of the three roots of cardio-cerebro-renovascular disease affecting up to 25% of the adult population. Hence, high blood pressure should be recognized and treated, to reduce any complications and prolong life, as noted by Michael Weber of the Veterans Administration Hospital in Long Beach, California. He further emphasizes the need for monitoring before one starts the treatment of high blood pressure. Indeed, he refers to the results of the Australian study on mild hypertension with a large percentage of placebo responders and rightly suggests that many people are treated who should not be because of 'white-coat-associated high blood pressure'. He also points to the lack of standardization of techniques for data analysis and of methods of BP measurement. Ambulatory monitoring under usual condi tions without concomitant recording of events does not allow even a qualitative assessment of the impact of varying stimuli, in weber's opinion.
