The ground state and the first excited state of He are investigated in harmonic oscillator shellmodel bases including all the configurations up to 1$6co excitation energy. The Gogny et al. potential and versions I/III and V of the Malfliet-Tjon potential are used in the calculation. The difficulties in describing these states in a consistent manner are not overcome by substantially enlarging the shell-model bases. The lowest eigenvalue with a 1Acu center-of-mass wave function is also extracted from the energy matrices, providing the absolute energy of the first J = 1, T =0 level. It is found that the agreement with experiment for this level is significantly improved when the model space is enlarged.
This study explores the criticality of design that contributes to discernable differential in the experiences of goal-focused shoppers on European dress model Web sites. Focused on the apparel industry in the European Union, the study examines accessibility and convenience, availability of information, lack of sociality, media richness, and product selection, extending the technology acceptance model (TAM). The findings of the study suggest that fundamental functionality is more helpful than advanced richness or sophistication of technology on dress model sites. The study was conducted as a laboratory experiment with adult students at a leading European business university, in comparison to and in continuance of an earlier project on American Web sites with American students at a major university in the United States, in which the findings on media richness were replicated in this study. These findings will benefit European marketing practitioners and researchers who review the impact of dress model technology on shopping Web sites.
This study analyzes design factors that contribute to the intention of goal-focused consumers to buy apparel on European Web sites that have dress model technology. Factors from academic literature of perceived ease of use, perceived usefulness, media richness of technology, decision satisfaction, and behavioral intention to return are especially examined in the study. The results confirm earlier exploratory studies by the authors in 2007 and 2006 positing media richness of dress model technology as less important in intention to buy than the other factors and begin to indicate that the technology is not important in facilitating electronic customer relationship management (e-CRM) on the Web. The study was conducted as an experiment with adult goalfocused students of a leading Belgian business university as proxy shoppers of the Web sites. The results of this study will benefit both European and American e-Business designers and managers considering direction and further investment in multimedia technologies on apparel Web sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
