We investigate two key group-level determinants of virtual community participation—group norms and social identity—and consider their motivational antecedents and mediators. We also introduce a marketing-relevant typology to conceptualize virtual communities, based on the distinction between network-based and small-group-based virtual communities. Our(More)
Building on the theory of planned behaviour (TPB), we develop a new model of purposive behaviour which suggests that desires are the proximal causes of intentions, and the traditional antecedents in the TPB work through desires. In addition, perceived consequences of goal achievement and goal failure are modelled as anticipated emotions, which also function(More)
Theory development typically focuses on relationships among theoretical constructs, placing little emphasis on relationships between constructs and measures. In most cases, constructs are treated as causes of their measures. However, this causal flow is sometimes reversed, such that measures are viewed as causes of constructs. Procedures have been developed(More)
The purpose of this study is to distinguish between cognitive, affective and evaluative components of social identity in the organization and to show how the components instigate behaviours that benefit in-group members. A new scale for measuring cognitive organizational identification (i.e. self-categorization) is developed and compared to a leading scale.(More)
D. Howell, E. Breivik, and J. B. Wilcox (2007) have presented an important and interesting analysis of formative measurement and have recommended that researchers abandon such an approach in favor of reflective measurement. The author agrees with their recommendations but disagrees with some of the bases for their conclusions. He suggests that although(More)
A structural equation methodology is used to assess the reliability and validity of expectancy-value and semantic differential measures of attitude toward the act of donating blood. Hypotheses as to the internal consistency and the convergent, concurrent, discriminant, predictive, and nomological validities of responses are tested in the context of a(More)
Despite renewed interest and many advances in methodology in recent years, information systems and organizational researchers face confusing and inconsistent guidance on how to choose amongst, implement, and interpret findings from the use of different measurement procedures. In this article, the related topics of measurement and construct validity are(More)
The results of a survey on the activities and functions of hospital-based pharmacy and therapeutics (P&T) committees are presented. Questionnaires were mailed to the pharmacy director or the person responsible for the pharmacy's drug information service at 267 teaching hospitals throughout the United States in 1994 and 1995. The survey questions covered P&T(More)
