Political instrumentality perceptions and desires for union representation

This paper examines the concept of union instrumentality in light of theoretical literature and contemporary trends in union political activity. A broad concept of union instrumentality, including a place for the concept of union political instrumentality (e.g., union influence on general elections or legislation), is suggested. The practical importance and applicability of the political instrumentality concept is demonstrated in empirical models of nonunion worker voting intent in union representation elections. As predicted, workers perceiving higher levels of union political instrumentality are significantly more likely than others to indicate a pro-union voting intent. Given the importance of political versus economic activity as a defining characteristic of labor movements and given recent increases in political activity by U.S. unions, these results have significant implications for the way we think about U.S. unions and for future union organizing and political activities.

The relationship between socioeconomic status and infant mortality in a metropolitan aggregate, 1989–1991

This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in a metropolitan aggregate comprised of seven of the larger cities in Ohio during the three years centering on the 1990 census. Using a summary income score derived for the census tract of mother's usual residence, the census tracts in the seven metropolitan centers were divided into broad income groupings and three-year average infant mortality rates were computed for each area, by age, sex, race, and selected causes of death. The most important conclusion to be drawn from the data is that in spite of some remarkable declines in overall levels of infant mortality during the past few decades, there continues to be a very clear and pronounced inverse association between income status and infant mortality. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of infant death. At the same time, the data reveal notable differences in the magnitude of the relationship by sex, and especially by age at death, race, and cause of death. Explanations of these differences are suggested, and a conclusion notes some of the difficulties encountered in developing programs aimed at closing the infant mortality gap between the richest and poorest segments of the society.This is an expanded version of a paper presented at the annual meetings of the Eastern Sociological Society in Baltimore, Maryland (March 17–20, 1994).     

Intraindustry division of labor: The states of Mexico

Measures of occupational differentiation in each of eight industries vary markedly among the states of Mexico, a finding that is construed as evidence of territorial divergence in economic development. The relation among states between the relative size of an industry and the amount of occupational differentiation is direct for some industries but inverse for others. The interpretation is that industry size and intraindustry division of labor are directly related only to the extent that the labor force is concentrated territorially. Findings for the states of Mexico 1950 and 1960 are consistent with the interpretation.     

Detection of biotic responses to urbanization using fish assemblages from small streams of western Georgia,USA

We examined relationships between stream fish assemblages and land use alteration associated with urbanization in 15 lower Piedmont watersheds along an urbanization gradient north of Columbus, western Georgia. Based on land cover data from 2002 Landsat 7 TM imagery aerial photos, streams drained watersheds that were largely urban, developing (suburban), agricultural (pasture), managed pine forest, and unmanaged mixed-forest. We quantified fish seasonally from 3 run-pool segments in each stream, and used a variety of metrics as response variables in analyses of relationships between fish assemblage structure and land use and natural basin variation. In general, Georgia-Index of Biotic Integrity (GA-IBI) values, Bray-Curtis faunal similarity of streams to mean conditions within reference streams, proportions of fish as lithophilic spawners, and fish lacking eroded fins, lesions, tumors decreased with increasing urbanization. Multiple regression indicated that assemblages were explained by a combination of land use and natural basin variables (basin size, average discharge, nearest distance to a larger downstream tributary [colonization source]), with land use variables being important predictors of summer assemblages and natural basin variables being more important in winter and spring assemblages. Non-metric multidimensional scaling (NMDS) ordinations revealed strong separation between assemblages in urban watersheds and forested watersheds, whereas assemblages in agricultural and developing watersheds were intermediate between those in urban and forested watersheds. Our data suggest that fish are reliable indicators of anthropogenic disturbance at the landscape scale, at least seasonally, and may be used to forecast the magnitude of landscape-level changes in stream structure and function associated with the conversion of forests to urban/suburban land in the Southeast.     

Movement and structure as determinants of spatial representations

It was hypothesized that the cognitive representation of distances between locations in an environment is a function not only of the environment's structure, but also of a person's pattern of travel within the environment. In the present study subjects were exposed to an experimental environment in which some locations were separated either by an opaque or a transparent barrier and other locations were not separated by any barrier. As subjects learned where the locations were, they were required to follow a specific route that allowed travel between some locations in each category but not others. Afterward subjects were asked to reproduce from memory the separation between pairs of locations. The results supported the hypothesis. Recalled distance between locations was significantly affected by both movement patterns of subjects and structural aspects of the environment (type of barrier and actual separation between locations). These results are interpreted in terms of the types of information made available through particular movement patterns and the corresponding salience of that information.
