This study investigates the adoption of total cost of ownership (TCO) analysis to improve sourcing decisions. TCO can be seen as an application of activity based costing (ABC) that quantifies the costs that are involved in acquiring and using purchased goods or services. TCO supports purchasing decision-makers in focusing on total value received and not simply price, and it extends ABC concepts...

In this study, seven factors affecting consumer perception of online store image are identified based on store image measurement of traditional stores. Enjoyment and trustworthiness are two new antecedents suggested for the online store image. A cultural dimension is also introduced to understand the possible differences of model structure and relationships between online store image perception...

The rapid growth in online sales shows that online purchase has become a mainstream for modern consumers to acquire goods and services. In this research, we propose to use Prospect Theory as the theoretical basis to account for consumers’ psychological states in an online purchasing environment. In particular, we aim to empirically investigate whether social comparison acts as an essential fact...

In this article, we identify success factors for managing small and intensive purchasing groups by comparing successful and unsuccessful Dutch purchasing groups in a large-scale survey. Transaction costs economics and social exchange theory are used as theoretical frameworks for our broad empirical investigation. We found that the success factors studied that are related to interorganizational ...

BACKGROUND AND PURPOSE Differences in definitions of socioeconomic status and between study designs hinder their comparability across countries. We aimed to analyze the correlation between 3 widely used macrosocioeconomic status indicators and clinical outcomes. METHODS We selected population-based studies reporting incident stroke risk and/or 30-day case-fatality according to prespecified cr...

These network approach models emphasize “understandi...

Suppose there is a collection x1, x2, . . . , xN of independent uniform [0, 1] random variables, and a hypergraph F of target structures on the vertex set {1, . . . , N}. We would like to purchase a target structure at small cost, but we do not know all the costs xi ahead of time. Instead, we inspect the random variables xi one at a time, and after each inspection, choose to either keep the ver...
