“Doctors Do Too Little Technology”: A Longitudinal Field Study of an Electronic Healthcare System Implementation

Abstract: With the strong ongoing push toward investment in and deployment of electronic healthcare (e-healthcare) systems, understanding the factors that drive the use of such systems and the consequences of using such systems is of scientific and practical significance. Elaborate training in new e-healthcare systems is not a luxury that is typically available to healthcare professionals---i.e., doctors, paraprofessionals (e.g., nurses) and administrative personnel---because of the 24 × 7 nature and criticality of operations of healthcare organizations, especially hospitals, thus making peer interactions and support a key driver of or barrier to such e-healthcare system use. Against this backdrop, using social networks as a theoretical lens, this paper presents a nomological network related to e-healthcare system use. A longitudinal study of an e-healthcare system implementation, with data gathered from doctors, paraprofessionals, administrative personnel, patients, and usage logs lent support to the hypotheses that: (1) ingroup and outgroup ties to doctors negatively affect use in all user groups; (2) ingroup and outgroup ties to paraprofessionals and administrative personnel positively affect use in both those groups, but have no effect on doctors' use; and (3) use contributes positively to patient satisfaction mediated by healthcare quality variables---i.e., technical quality, communication, interpersonal interactions, and time spent. This work contributes to the theory and practice related to the success of e-healthcare system use in particular, and information systems in general.

With a Little Help from Your Friends: The Importance of High-quality Friendships on Early Adolescent Adjustment

Abstract: The unique contributions of peer acceptance, friendship, and victimization to adjustment were examined. How these relational systems moderate the influence of one another to influence adjustment was also investigated. Friendship quality, a unique aspect of friendship, was expected to be especially important for adjustment when other relational systems were poor. A total of 238 fifth to eighth graders (boys = 109) participated in the survey-style paradigm. Youth participants completed measures assessing their friendships and peer relationships. Teachers provided assessments of adjustment. Adolescents who had lower levels of peer acceptance, number of friends, and friendship quality had greater teacher-reported maladjustment. Friendship quality was also an important buffer against adjustment problems when peer acceptance and number of friends were low.The outcomes of this article suggest that an approach that includes examining the quality of adolescents’ friendships, peer interactions, and interactive models of relationship dimensions are informative for understanding adolescents’ general adjustment.

Physics of Ultrathin Films and Heterostructures of Rare-Earth Nickelates

Abstract: The electronic structure of transition metal oxides featuring correlated electrons can be rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of the present paradigms of electronic behavior, we focus on the physics of rare-earth nickelates as an archetype of complexity emerging within the charge transfer regime. The intriguing prospect of realizing the physics of high-Tc cuprates through heterostructuring resulted in a massive endeavor to epitaxially stabilize these materials in ultrathin form. A plethora of new phenomena unfolded in such artificial structures due to the effect of epitaxial strain, quantum confinement, and interfacial charge transfer. Here we review the present status of artificial rare-earth nickelates in an effort to uncover the interconnection between the electronic and magnetic behavior and the underlying crystal structure. We conclude by discussing future directions to disentangle the puzzle regarding the origin of the metal-insulator transition, th...
