    The purpose of this paper is to investigate the prospective effect of affective commitment on relationship IT capability, and also investigate the role that relationship information exchange plays to support IT capability in industrial markets. Building on information systems research and business relationship research, a research model is developed and tested with LISREL on a sample of 353 customer-relationships of Swedish industrial firms. The results show that affective commitment in business relationships serves as a fundament that strengthens IT capability, when the exchange of information is important to a relationship. Interestingly enough, the LISREL-analysis provides empirical evidence that the effect of affective commitment on IT capability is mediated by information exchange in business relationships, but that the path from affective commitment to IT capability is not significant. Well-functioning information exchange systems are, thus, vital for affective commitment to impact IT capabilities in business relationship settings. This finding contributes with new knowledge about the role of emotions as prerequisites of IT capability development in the interfirm business relationships of industrial firms. The results highlight the importance of emotional bonds to support the development of interfirm IT capabilit

    Digital Transformation of Global Business Processes: The Role of Dual Embeddedness

    While much existing research on MNC digital transformation has followed a linear design and implementation logic using cross-sectional data, the multiple and divergent needs of headquarters (HQ) and subsidiaries suggest that MNC digital transformation actually involves a more iterative journey. In this paper, we apply the theoretical perspective of embeddedness to better define the complexities of MNC digital transformation, and identify how HQ and subsidiaries can navigate the complexities. This paper presents a longitudinal multi-case study of five Forbes Global 2000 firms that are HQ in Europe with large subsidiaries in the U.S. We find that the process of digital transformation is significantly influenced by internal embeddedness (relationship of HQ with subsidiaries and across subsidiaries) and external embeddedness (relationship of subsidiaries with their local markets), and also by strategy, financial and technology considerations. While HQ and subsidiaries have different perspectives, an understanding of these influences can help HQ and subsidiaries navigate digital transformation

    Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to accurately derive disk properties, we need a thorough understanding of the behavior of the molecular probes we rely on. Here we investigate how the molecular line emission of N2_2H+^+, HCO+^+, HCN, and C18^{18}O compare to other measured quantities in a set of 20 protoplanetary disks. Overall, we find positive correlations between multiple line fluxes and the disk dust mass and radius. We also generally find strong positive correlations between the line fluxes of different molecular species. However, some disks do show noticeable differences in the relative fluxes of N2_2H+^+, HCO+^+, HCN, and C18^{18}O. These differences occur even within a single star-forming region. This results in a potentially large range of different disk masses and chemical compositions for systems of similar age and birth environment. While we make preliminary comparisons of molecular fluxes across different star-forming regions, more complete and uniform samples are needed in the future to search for trends with birth environment or age.Comment: Accepted for publication in The Astrophysical Journa

    A Systematic Classification of the Congenital Bronchopulmonary Vascular Malformations: Dysmorphogeneses of the Primitive Foregut System and the Primitive Aortic Arch System

    Purpose: We reviewed the cases of 33 patients from our clinic and 142 patients from the literature with congenital bronchopulmonary vascular malformations (BPVM), systematically analyzed the bronchopulmonary airways , pulmonary arterial supplies, and pulmonary venous drainages, and classified these patients by pulmonary malinosculation( PM). Materials and Methods: From January 1990 to January 2007, a total of 33 patients (17 men or boys and 16 women or girls), aged I day to 24 years (median, 2.5 months), with congenital BPVM were included in this study. Profiles of clinical manifestations, chest radiographs, echocardiographs , esophagographs, computer tomography (CT), magnetic resonance imaging (MRI) , magnetic resonance angiography (MRA ), cardiac catheterizations with angiography, contrast bronchographs, bronchoscopies, chromosomal studies, surgeries, and autopsies of these patients were analyzed to confirm the diagnosis of congenital BPVM. A total of 142 cases from the literature were also reviewed and classified similarly. Results: The malformations of our 33 patients can be classified as type A isolated bronchial PM in 13 patients, type B isolated arterial PM in three, type C isolated venous PM in two, type D mixed bronchoarterial PM in five, type F mixed arteriovenous PM in one, and type G mixed bronchoarteriovenous PM in nine. Conclusion: Dysmorphogeneses of the primitive foregut system and the primitive aortic arch system may lead to haphazard malinosculations of the airways, arteries, and veins of the lung. A systematic classification of patients with congenital BPVM is clinically feasible by assessing the three basic bronchovascular systems of the lung independently
