Many systems for utilizing the heat energy in municipal refuse are in various stages of development. These systems either use unprocessed solid waste as a fuel or derive a fuel through processing. The fuels produced vary radically in heating value. The energy expended in processing differs from one process to another and the potential end use is not the same for each system. Six representative systems are compared to determine the relative potential value of refuse as a source of energy.

Abstract. This study explores the relative value of both subjectively reported cognitive speed and gait speed in association with objectively derived cognitive speed. It also explores how these factors are affected by psychological and physical well-being. A group of 90 cognitively healthy older adults ( M = 73.38, SD = 8.06 years, range = 60–89 years) were tested in a three-task cognitive battery to determine objective cognitive speed as well as measures of gait speed, well-being, and subjective cognitive speed. Analyses indicated that gait speed was associated with objective cognitive speed to a greater degree than was subjective report, the latter being more closely related to well-being than to objective cognitive speed. These results were largely invariant across the 30-year age range of our older adult sample.

Managing Stress

Abstract. Despite the substantial attention paid to stress management in the extant coping literature, media use has been surprisingly overlooked as a strategy worthy of close examination. Although media scholars have suggested media use may be driven by a need to relax, related research has been sporadic and, until recently, disconnected from the larger conversation about stress management. The present research aimed to determine the relative value of media use within the broader range of coping strategies. Based on surveys of both students and breast cancer patients, media use emerged as one of the most frequently selected strategies for managing stress across a range of personality and individual difference variables. Further, heavier television consumers and those with higher perceived stress were also more likely to use media for coping purposes. Finally, those who choose media for stress management reported it to be an effective tool, although perhaps not as effective as other popular strategies. This research not only documents the centrality of media use in the corpus of stress management techniques, thus highlighting the value of academic inquiry into media-based coping, but it also offers evidence supporting the positive role media use can play in promoting psychological well-being.
