An Empirical Comparison of Consumer Innovation Adoption Models: Implications for Subsistence Marketplaces

So called “pro-poor” innovations may improve consumer wellbeing in subsistence marketplaces. However, there is little research that integrates the area with the vast literature on innovation adoption. Using a questionnaire where respondents were asked to provide their evaluations about a mobile banking innovation, this research fills this gap by providing empirical evidence of the applicability of existing innovation adoption models in subsistence marketplaces. The study was conducted in Bangladesh among a geographically dispersed sample. The data collected allowed an empirical comparison of models in a subsistence context. The research reveals the most useful models in this context to be the Value Based Adoption Model and the Consumer Acceptance of Technology model. In light of these findings and further examination of the model comparison results the research also shows that consumers in subsistence marketplaces are not just motivated by functionality and economic needs. If organizations cannot enhance the hedonic attributes of a pro-poor innovation, and reduce the internal/external constraints related to adoption of that pro-poor innovation, then adoption intention by consumers will be lower

Development of tolerance to class ii-mismatched renal transplants after a short course of cyclosporine therapy in miniature swine

Our laboratory has reported previously spontaneous acceptance of class II-matched, single haplotype (but not 2 haplotype), class I-mismatched renal allografts in miniature swine. All class II-mismatched animals rejected acutely regardless of class I matching. We have also demonstrated recently that a short course of high dose (10 mg/kg/day for 12 days) CsA uniformly induces donor-specific tolerance to 2-haplotype, class I-mismatched renal allografts. The survival of 2-haplotype, fully MHC mismatched renal allografts was prolonged by the same treatment, but tolerance was not induced, as all animals rejected eventually. We have now tested this short course of immunosuppressive therapy for its effect on renal allografts mismatched selectively for 2 haplotypes at class II. We have observed long-term graft survival in 5 of 7 animals under these conditions. Each of the 5 acceptor animals was demonstrated to be specifically tolerant by its response either to donor-matched skin grafts or to a second donor-matched kidney transplant without further immunosuppression. These data suggest the existence of a common pathway for induction of specific transplantation tolerance to MHC antigens when these antigens are recognized on vascular endothelium under conditions of altered cytokine production. They also suggest that tolerance induction under these conditions requires matching for either class I or class II antigens, which may have implications for the mechanism by which peripheral tolerance is induced, as well as practical implications for the extension of these results to potential clinical practice. © 1994 by Williams & Wilkins
