The impact of victimization experiences and crime-related variables on act-specific fear of crime are reinvestigated. Perceived risk and vulnerability to crime were expected to mediate the influence of demographic and crime-related variables on fear. The results of this study suggest that fear of property loss is more explainable by crime-related variables than is fear of violent victimization. Perceptual variables diminish the direct impact of victimization experiences and local crime rate on each type of fear of crime. However, particular demographic and crime-related variables have different effects on fear of property loss and fear of violent crime. The paper concludes with suggestions for future research on the social determinants of fear of crime among the elderly. [ABSTRACT FROM AUTHOR]

Costner (1965) showed that many of the most commonly used measures of association may be conceptually interpreted as indicating proportional reduction in prediction error. But because it is verbally cumbersome, and conceptually complex for some measures, the proportional reduction in error interpretation has not been widely incorporated in research reports where appropriate. Instead, measures of association continue to be interpreted in abstract terms distinguishing between broad levels of strength. This paper demonstrates that all proportional reduction in error measures of association may be alternately interpreted as indicating the percent of variation explained. Because this interpretation is conceptually meaningful in a manner highly relevant for scientific investigation, more convenient to apply in research reports, and already familiar to most social scientists, it is argued that it be standardly applied to all proportional reduction in error measures.

Maintenance, an important concept in the organizational literature, is often assumed to be a key factor in the low levels of sensitivity to client needs and demands apparent in many human service organizations. This paper uses data from a national sample of juvenile courts to demonstrate, however, that maintenance may relate to other variables in ways that are at variance with the common assumption. The maintenance of internal organizational operations is bound closely to the development of ties to the community; as a result, strong emphasis on maintenance actually leads to high levels of sensitivity to clients when certain environmental forces demand it. This positive relation is especially strong when organizations are highly vulnerable to external pressures. Such results suggest a contingent view of the role of maintenance in organizations and imply some further directions for research. [ABSTRACT FROM AUTHOR]
