Aging and its effects on a person's quality of life are a growing health concern and burden for many Americans. Recently, studies have shown that adopting certain healthy behaviors may help maintain and or prevent age-related health issues such as cognitive decline. However, many people are unaware of these newfound facts. Furthermore, there is insufficient research evidence to understand how older adults view brain health and the differences between diverse groups of older adults. This study examines brain health knowledge and behaviors among Caucasian and African-American community-dwelling older adults in North Carolina. Findings were significant for level of education and total brain health knowledge scores, though there were no significant differences between races. In addition, there was a significant association between total number of health conditions and total brain health knowledge scores that warrants further study. 相似文献

This essay applies Richard Gregg's theory of protest rhetoric to 705 American social movement songs from 1800 to 1985 to discover how songs enable protestors to identify against others and thus to locate themselves positively in the social hierarchy. Songs are ideal messages for ego‐enhancement because they are movement‐centered, concerned with social relationships, and highly self‐directed. Terms denoting innocent victimage and wicked victimizer dominate the selected songs, and the vision of reality is negative, dangerous, threatening, and unfair. Relatively few songs emphasize the unity, virtue, wisdom, or bravery of protestors. The self‐image contained in songs does not appear to express a strongly positive identity or locate the oppressed very high in the symbolic or social hierarchy. This self‐image would seem to fulfill three ego functions essential for the early phases of social movements: raising consciousness, allaying guilt, and reclaiming or proclaiming one's ego. However, a different self‐image is needed as movements grow, confront opposition successfully, achieve some goals, suffer setbacks, and splinter into factions. This analysis of songs indicates that protestors have difficulty making the essential transition from a self‐image of victim to one of power, worth, and virtue. They cannot extricate themselves from symbolically defensive positions in a hostile environment. 相似文献
