Predicting different conceptualizations of system use: the competing roles of behavioral intention, facilitating conditions, and behavioral expectation

Abstract: Employees' underutilization of new information systems undermines organizations' efforts to gain benefits from such systems. The two main predictors of individual-level system use in prior research-behavioral intention and facilitating conditions-have limitations that we discuss. We introduce behavioral expectation as a predictor that addresses some of the key limitations and provides a better understanding of system use. System use is examined in terms of three key conceptualizations: duration, frequency, and intensity. We develop a model that employs behavioral intention, facilitating conditions, and behavioral expectation as predictors of the three conceptualizations of system use. We argue that each of these three determinants play different roles in predicting each of the three conceptualizations of system use. We test the proposed model in the context of a longitudinal field study of 321 users of a new information system. The model explains 65 percent, 60 percent, and 60 percent of the variance in duration, frequency, and intensity of system use respectively. We offer theoretical and practical implications for our findings.

Biofilm Formation by Plant-Associated Bacteria

Abstract: Plants support a diverse array of bacteria, including parasites, mutualists, and commensals on and around their roots, in the vasculature, and on aerial tissues These microbes have a profound influence on plant health and productivity Bacteria physically interact with surfaces to form complex multicellular and often multispecies assemblies, including biofilms and smaller aggregates There is growing appreciation that the intensity, duration, and outcome of plant-microbe interactions are significantly influenced by the conformation of adherent microbial populations Biofilms on different tissues have unique properties, reflecting the prevailing conditions at those sites Attachment is required for biofilm formation, and bacteria interact with plant tissues through adhesins including polysaccharides and surface proteins, with initial contact often mediated by active motility Recognition between lectins and their cognate carbohydrates is a common means of specificity Biofilm development and the resulting intimate interactions with plants often require cell-cell communication between colonizing bacteria

Feminist Attitudes and Support for Gender Equality: Opinion Change in Women and Men, 1974–1998

Abstract: This article examines attitudes related to feminism and gender equality by evaluating the trends in, and determinants of women and men's attitudes from 1974 to 1998. Past accounts suggest two clusters of explanations based on interests and exposure. Using these, we examine opinions on abortion, sexual behavior, public sphere gender roles, and family responsibilities. We find that attitudes have continued to liberalize and converge with the exception of abortion attitudes. The determinants of feminist opinion vary across domains, but have been largely stable. While not identical, the predictors of men and women's opinions are similar The results suggest the need for more attention to the mechanisms underlying the production of feminist opinions and theoretical integration of both interests and exposure in a dynamic process.
