A large information systems implementation (such as Enterprise Resource Planning systems) relies on the trust of its stakeholders to succeed. Such projects impact diverse groups of stakeholders, each with their legitimate interests and expectations. Levels of stakeholder trust can be expected to vary in large-scale implementations (which can take several years), and cannot be taken for granted. Previous studies have largely focused on the taxonomic deconstruction of the trust construct, through point-in-time variance studies. They have identified the relationship between trust and project outcomes, but largely ignored the dynamics of trust relations. Giddens, as part of his study of modernity, theorises trust dynamics in relation to abstract social systems, though without focusing on information systems. We use Giddens’ concepts to investigate evolving trust relationships in a longitudinal case analysis of a large Integrated Hospital System implementation for the Faroe Islands. Trust relationships suffered a serious breakdown, but the project was able to recover and meet its goals. We develop six theoretical propositions theorising the relationship between trust and project outcomes, the maintenance, breakdown and restoration of trust, the role of the information system in restoring trust, and the emergent and reciprocal nature of trust and project outcomes. 相似文献

An important aspect of the successful implementation of large information systems (such as Enterprise Resource Planning (ERP) systems) is trust. These implementations impact the legitimate interests of many groups of stakeholders, and trust is a critical factor for success. Trust in the project is contingent upon many factors, is likely to vary over time and should not be taken for granted. Previous studies have identified the relationship between trust and project outcomes and suggested trust‐building strategies but have largely ignored the dynamic quality of trust relations through the life of a major project and the complex demands of managing those fluctuations. We investigate evolving trust relationships in a longitudinal case analysis of a large integrated hospital system implementation for the Faroe Islands. Trust relationships suffered various breakdowns, but the project was able to recover and eventually meet its goals. Based on concepts from Giddens' later work on modernity, we develop two approaches for managing dynamic trust relationships in implementation projects: decoupling and re‐engaging. 相似文献

The influence of food intake on the bioavailability of isoniazid (INH) has been examined in nine healthy male volunteers. INH was administered as a single oral dose, both in fasting state and together with a standardized breakfast. Numerous venous blood samples were obtained 5 min-6 hours after the INH ingestion, and the concentrations of unmetabolized INH in serum were assessed by spectrophotometry. The observations indicate that both the peak concentration and the total amount of INH absorbed are greatly reduced when the drug is ingested together with food. Hence it is recommended that, in the treatment of tuberculosis with INH, the drug should be given on an empty stomach. The data may also have some bearing on the use of INH for assessing acetylation rates and estimating dosages of hydralazine and related drugs. 相似文献

The use of Pedersen's λ function to evaluate electrostatic probe measurements of charged dielectric surfaces is demonstrated. With a knowledge of the probe λ function, the procedure by which this function is employed is developed, and thereafter applied to a set of experimental measurements available in the literature. The values of surface charge density derived are in good agreement with the published data. Through this field-theoretical approach, it is readily shown that areas of charge remote from the probe location can produce a major part of the probe signal. If a circuit-theory approach were adopted to analyze such probe measurements, then as the held features of the probe response cannot be taken into account, a serious misinterpretation of the measurements could arise 相似文献
