Selected AbstractsInteraction Effects in the Theory of Planned Behavior: The Interplay of Self-Identity and Past BehaviorJOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 11 2007Joanne R. Smith This research used a revised theory of planned behavior (TPB) model, which incorporated self-identity and past behavior,and the interaction between these constructs,in order to improve the model's predictive power in relation to consumer behavior (purchasing one's preferred beer). At Time 1, respondents (N = 108) completed measures of attitudes, perceived behavioral control, subjective norm, self-identity, past behavior, and intentions. Behavior was assessed 1 week later. All predictors were positively related to intentions. Self-identity and past behavior interacted to influence intentions: Self-identity had a stronger influence on intentions at low, rather than high, levels of past behavior. Intentions and past behavior were predictive of Time 2 behavior. These findings emphasize the need to consider identity issues in the TPB. [source] Charitable giving: the effectiveness of a revised theory of planned behaviour model in predicting donating intentions and behaviourJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 5 2007Joanne R. Smith Abstract A revised theory of planned behaviour (TPB) model was used to determine the influence of attitudes, norms (injunctive, descriptive and moral norms), perceived behavioural control, and past behaviour on intentions to donate money to charitable organisations. Respondents (N,=,227) completed a questionnaire assessing the constructs of the revised TPB model. Four weeks later, a subsample of respondents (N,=,67) reported their donating behaviour. Hierarchical multiple regression analyses revealed support for the revised TPB model. Attitudes, perceived behavioural control, injunctive norms, moral norms and past behaviour all predicted charitable giving intentions; however, descriptive norms did not predict donating intentions. Donating intentions were the only significant predictor of donating behaviour at Time 2. In addition, a number of beliefs differentiated between those who did and did not intend to donate to charity. Theoretical and applied implications of the results are discussed. Copyright © 2007 John Wiley & Sons, Ltd. [source] Tissue factor and tissue factor pathway inhibitorANAESTHESIA, Issue 5 2004G. C. Price Summary The classical ,cascade/waterfall' hypothesis formulated to explain in vitro coagulation organised the amplification processes into the intrinsic and extrinsic pathways. Recent molecular biology and clinical data indicate that tissue factor/factor-VII interaction is the primary cellular initiator of coagulation in vivo. The process of blood coagulation is divided into an initiation phase followed by a propagation phase. The discovery of tissue factor pathway inhibitor further supports the revised theory of coagulation. Tissue factor is also a signalling receptor. Recent evidence has shown that blood-borne tissue factor has an important procoagulant function in sepsis, atherosclerosis and cancer, and other functions beyond haemostasis such as immune function and metastases.
