Trust and control interrelations: New perspectives on the trust control nexus

This article is the post-print version of the published article that may be accessed at the link below. Copyright @ 2007 Sage Publications.This article introduces the special issue on New Perspectives on the Trust-Control Nexus in Organizational Relations. Trust and control are interlinked processes commonly seen as key to reach effectiveness in inter- and intraorganizational relations. The relation between trust and control is, however, a complex one, and research into this relation has given rise to various and contradictory interpretations of how trust and control relate. A well-known discussion is directed at whether trust and control are better conceived as substitutes, or as complementary mechanisms of governance. The articles in this special issue bring the discussion on the relationship between both concepts a step further by identifying common factors, distinctive mechanisms, and key implications relevant for theory building and empirical research. By studying trust and control through different perspectives and at different levels of analysis, the articles provide new theoretical insights and empirical evidence on the foundations of the trust-control interrelations

Управление финансовым состоянием предприятия (на примере СП ОАО «Спартак»)

The purpose of this paper is to explore the characteristics of information systems (IS) maintenance within an IT and organizational setting. We discuss the characteristics of maintenance objects’ focus and content. Our results are based on qualitative case studies. In this paper a case study of a Swedish Bank is used to illustrate our discussion. Our findings show that maintenance objects can be defined by processes and/or functions or products and/or services within an organizational setting. This is done in order to increase a business perspective in maintenance management and to clarify roles of responsibility for organizational changes required from new IT capabilities. According to our findings maintenance objects can contain business solutions and IT solutions. This implies that business beneficial maintenance is supported by close cooperation between actors from the organizational setting and the IT organization. The result of the paper is a characterization of IS maintenance through definition of maintenance objects’ focus and content

Expression of the mucosal γδ T cell receptor V region repertoire in patients with IgA nephropathy

IgA nephropathy (IgAN) is characterized by the deposition of IgA in the glomerular mesangium and often leads to progressive renal dysfunction and kidney failure. We have previously shown that the mesangial IgA is likely to derive from the bone marrow plasma cells, and suggested that a primary abnormality within the mucosal immune system may underly the pathogenesis of IgAN. This study has analyzed the T cell receptor (TCR) variable (V) region expression by γδ T cells in the intestinal mucosa of patients with IgAN. The Vγ, and Vδ usage of TCR transcripts was determined using a semiquantitative reverse transcriptase-PCR protocol. Primers specific for the four human Vγ, and six Vδ subfamilies were used each with a constant (c) γ or Cδ specific primer, and the PCR-amplified TCR transcripts were detected by Southern blotting and oligonucleotide hybridization. γδ TCR V region expression was determined in gut biopsies and peripheral blood of 11 patients with IgAN, and the TCR Vγ and Vδ repertoires were compared to those in gut and peripheral blood of 11 control individuals. γδ T cells in normal blood predominantly expressed Vγ2 (Vγ9 gene) and Vδ2 gene segments whereas those in normal gut mainly expressed Vγ3 and Vδ3. In IgAN patients, Vδ2 was also the predominant Vδ gene utilized by peripheral blood γδ T cells, however, we observed a predominance of Vγ3 and reduced Vγ2 usage by these cells. γδ T cells in the gut of IgAN patients mainly used Vγ3 and Vδ1. While the γ and δ TCR V region repertoires did not differ significantly between the peripheral blood of patients and controls, there were significant differences in Vγ and Vδ repertoire expression between IgAN and control gut biopsies. Vγ3 gene expression was significantly decreased in IgAN gut compared to control gut (P = 0.023). In addition, there was a significant decrease in Vδ3 gene expression in IgAN gut compared to control gut (P = 0.043). These findings indicate that a subpopulation of γδ T cells, which represent the majority of γδ T cells in normal gut mucosa, are significantly diminished in the gut of patients with IgAN. This suggests that a 'hole' in the mucosal γδ T cell repertoire may play a fundamental role in contributing to the pathogenesis of IgAN
