A comprehensive conceptualization of post-adoptive behaviors associated with information technology enabled work systems

Abstract: For the last 25 years, organizations have invested heavily in information technology to support their work processes. In today's organizations, intra- and interorganizational work systems are increasingly IT-enabled. Available evidence, however, suggests the functional potential of these installed IT applications is underutilized. Most IT users apply a narrow band of features, operate at low levels of feature use, and rarely initiate extensions of the available features. We argue that organizations need aggressive tactics to encourage users to expand their use of installed IT-enabled work systems. This article strives to accomplish three primary research objectives. First, we offer a comprehensive research model aimed both at coalescing existing research on post-adoptive IT use behaviors and at directing future research on those factors that influence users to (continuously) exploit and extend the functionality built into IT applications. Second, in developing this comprehensive research model, we provide a window (for researchers across a variety of scientific disciplines interested in technology management) into the rich body of research regarding IT adoption, use, and diffusion. Finally, we discuss implications and recommend guidelines for research and practice.

Genome-wide association scan in women with systemic lupus erythematosus identifies susceptibility variants in ITGAM, PXK, KIAA1542 and other loci.

Abstract: Systemic lupus erythematosus (SLE) is a common systemic autoimmune disease with complex etiology but strong clustering in families (lambda(S) = approximately 30). We performed a genome-wide association scan using 317,501 SNPs in 720 women of European ancestry with SLE and in 2,337 controls, and we genotyped consistently associated SNPs in two additional independent sample sets totaling 1,846 affected women and 1,825 controls. Aside from the expected strong association between SLE and the HLA region on chromosome 6p21 and the previously confirmed non-HLA locus IRF5 on chromosome 7q32, we found evidence of association with replication (1.1 x 10(-7) or =9 other loci (P < 2 x 10(-7)). Our results show that numerous genes, some with known immune-related functions, predispose to SLE.

The NextGen Model Atmosphere Grid for 3000 ≤ Teff ≤ 10,000 K

Abstract: We present our NextGen Model Atmosphere grid for low-mass stars for effective temperatures larger than 3000 K. These LTE models are calculated with the same basic model assumptions and input physics as the VLMS part of the NextGen grid so that the complete grid can be used, e.g., for consistent stellar evolution calculations and for internally consistent analysis of cool star spectra. This grid is also the starting point for a large grid of detailed NLTE model atmospheres for dwarfs and giants. The models were calculated from 3000 to 10,000 K (in steps of 200 K) for 3.5{le}logthinspg{le}5.5 (in steps of 0.5) and metallicities of {minus}4.0{le}[M/H]{le}0.0. We discuss the results of the model calculations and compare our results to the Kurucz grid. Some comparisons to standard stars like Vega and the Sun are presented and compared with detailed NLTE calculations. {copyright} {ital {copyright} 1999.} {ital The American Astronomical Society}
