Adoption Rationale and Post-Adoption Activity: Institutional and Strategic Influences on EDI Adoption and Implementation

The purpose of this study was to explore the extent to which rationalistic and institutional considerations affect the decision to adopt information technologies and to explore how adoption rationales relate to the extent of implementation achieved after adoption. A multiple-case study approach was used. Institutional isomorphism rationales were more prevalent than strategic choice rationales. The most extensive implementations were found in organizations with a strategically-oriented rationale for adopting and/or extending use of EDI. The study also found evidence of a shift toward strategic choice rationales for EDI extension. These shifts in rationale originated to some extent in the same institutionally-based mechanisms that motivated the initial decisions to adopt the EDI technology

A tale of two liaisons: exploring library-writing center alliances

In this presentation, a writing center faculty member and a librarian will discuss their partnership at James Madison University, including how they have adapted the library liaison model for writing center use. Attendees will have the opportunity to consider models for writing center-library collaboration at their own institutions

Technology Use Rationale and Assimilation in the Implementation of Electronic Data Interchange

This study explores how rationales for information technology use relate to the extent of its assimilation in organizations and considers whether and how rationales associated with the technology-in-practice are transformed as the organization makes use of the technology. A multiple-case study of electronic data interchange (EDI) adoption and assimilation was analyzed, looking at both institutional and strategic rationales for EDI use. The degree of assimilation was greatest among those organizations that cited a strategically-oriented rationale for using EDI. The study also found evidence of a shift from institutional to strategic rationales in several organizations as they decided to extend their use of EDI beyond their initial implementation. Shifts in rationale emerged as organizational members gained greater exposure to the organizing vision of the larger EDI community and, to a lesser extent, as they experienced improvements in organizational performance through the use of EDI

Structural abnormalities in cortical volume, thickness, and surface area in 22q11.2 microdeletion syndrome: Relationship with psychotic symptoms.

Introduction22q11.2 deletion syndrome (22q11DS) represents one of the largest known genetic risk factors for psychosis, yet the neurobiological mechanisms underlying symptom development are not well understood. Here we conducted a cross-sectional study of 22q11DS to decompose cortical volume into its constituent parts, cortical thickness (CT) and surface area (SA), which are believed to have distinct neurodevelopmental origins.MethodsHigh-resolution T1-weighted scans were collected on 65 participants (31 22q11DS, 34 demographically comparable typically developing controls, 10-25 years old). Measures of cortical volume, CT, and SA were extracted from regions of interest using the FreeSurfer image analysis suite. Group differences and age-related trajectories in these structures, as well as their association with psychotic symptomatology, were assessed.ResultsRelative to controls, 22q11DS participants showed bilateral volumetric reductions in the inferior temporal cortex, fusiform gyrus, anterior cingulate, superior parietal cortex, and cuneus, which were driven by decreased SA in these regions. 22q11DS participants also had increased volumes, driven by increased CT, in bilateral insula regions. 22q11DS youth had increased CT in frontal regions, particularly middle frontal and medial orbitofrontal cortices. A pattern of age-associated cortical thinning was observed in typically developing controls in brain regions associated with visual and sensory information-processing (i.e., left pericalcarine cortex and fusiform gyrus, right lingual and postcentral cortices). However, this relationship was disrupted in 22q11DS participants. Finally, correlational analyses revealed that increased CT in right medial orbitofrontal cortex was associated with increased positive symptom severity in 22q11DS.ConclusionDifferential disruptions of CT and SA in distinct cortical regions in 22q11DS may indicate abnormalities in distinct developmental neural processes. Further, neuroanatomic abnormalities in medial frontal brain structures disproportionately affected in idiopathic schizophrenia were associated with psychotic symptom severity in 22q11DS youth, suggesting that disrupted biological processes in these cortical regions may underlie development of psychotic symptoms, both in 22q11DS and in the broader population

The Adoption of TradeNet by the Trading Community: An Empirical Analysis

This paper reports on a11empirical investigation of the adoption of TradeNet by the trading community in Singapore. Two issues are investigated. First, we examine the factors that determine the timing of TradeNet adoption by the trading community in a coercive institutional environment. Second, we analyze post-adoption performances of the trading community. Lessons on the implementation of IT at a nationwide level ensue
