Exchange and Power in Social Life

Abstract: In his landmark study of exchange and power in social life, Peter M. Blau contributes to an understanding of social structure by analyzing the social processes that govern the relations between individuals and groups. The basic question that Blau considers is: How does social life become organized into increasingly complex structures of associations among humans. This analysis, first published in 1964, represents a pioneering contribution to the sociological literature. Blau uses concepts of exchange, reciprocity, imbalance, and power to examine social life and to derive the more complex processes in social structure from the simpler ones. The principles of reciprocity and imbalance are used to derive such processes as power, changes in group structure; and the two major forces that govern the dynamics of complex social structures: the legitimization of organizing authority of increasing scope and the emergence of oppositions along different lines producing conflict and change.

The Cost of Inequality: Metropolitan Structure and Violent Crime

Abstract: The hypothesis tested is that variations in rates of urban criminal violence largely result from differences in racial inequality in socioeconomic conditions. Data on the 125 largest American metropolitan areas (SMSAs) are used to ascertain whether this hypothesis can account for three correlates of violent crime differently interpreted in the literature. Criminal violence is positively related to location in the South, which has been interpreted as the result of the Southern tradition of violence. It is positively related to the proportion of blacks in an SMSA, which has been interpreted as reflecting a subculture of violence in ghettos. And it is positively related to poverty, which has been interpreted as the emphasis on toughness and excitement in the culture of poverty. The analysis reveals that socioeconomic inequality between races, as well as economic inequality generally, increases rates of criminal violence, but once economic inequalities are controlled poverty no longer influences these rates, neither does Southern location, and the proportion of blacks in the population hardly does. These results imply that if there is a culture of violence, its roots are pronounced economic inequalities, especially if associated with ascribed position.

A Theoretical Extension of the Technology Acceptance Model: Four Longitudinal Field Studies

Abstract: The present research develops and tests a theoretical extension of the Technology Acceptance Model (TAM) that explains perceived usefulness and usage intentions in terms of social influence and cognitive instrumental processes. The extended model, referred to as TAM2, was tested using longitudinal data collected regarding four different systems at four organizations ( N = 156), two involving voluntary usage and two involving mandatory usage. Model constructs were measured at three points in time at each organization: preimplementation, one month postimplementation, and three months postimplementation. The extended model was strongly supported for all four organizations at all three points of measurement, accounting for 40%--60% of the variance in usefulness perceptions and 34%--52% of the variance in usage intentions. Both social influence processes (subjective norm, voluntariness, and image) and cognitive instrumental processes (job relevance, output quality, result demonstrability, and perceived ease of use) significantly influenced user acceptance. These findings advance theory and contribute to the foundation for future research aimed at improving our understanding of user adoption behavior.

Birds of a Feather: Homophily in Social Networks

Abstract: Similarity breeds connection. This principle—the homophily principle—structures network ties of every type, including marriage, friendship, work, advice, support, information transfer, exchange, comembership, and other types of relationship. The result is that people's personal networks are homogeneous with regard to many sociodemographic, behavioral, and intrapersonal characteristics. Homophily limits people's social worlds in a way that has powerful implications for the information they receive, the attitudes they form, and the interactions they experience. Homophily in race and ethnicity creates the strongest divides in our personal environments, with age, religion, education, occupation, and gender following in roughly that order. Geographic propinquity, families, organizations, and isomorphic positions in social systems all create contexts in which homophilous relations form. Ties between nonsimilar individuals also dissolve at a higher rate, which sets the stage for the formation of niches (localize...
