Using unique archival data on 81 projects from a major ERP vendor, we study whether transaction characteristics are included in the vendor’s estimation of risk to project profitability. We hypothesize that project size, contract type, strategic importance, and client familiarity are included in the risk estimations. Regression analysis suggests that, surprisingly, vendors do not include all tra...

In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...

Sixty-one percent (138/226) of Swiss inpatient and outpatient alcohol treatment programmes responded to a postal survey designed to assess the definition and acceptance of controlled drinking (CD) as a treatment objective, the degree to which a client's severity of dependence and finality of CD as an outcome goal were associated with acceptance, and the perceived value of selected client charac...

An ongoing discussion in IS research and practice emphasizes that divergent expectations of clients and vendors seem to contribute to outsourcing failures. Research in IS outsourcing has thus increasingly turned its attention to the role of relationship management between client and vendor. So far, studies have focused on addressing relationship factors in general, not taking different outsourc...

Understanding which adolescents remain in substance abuse treatment may facilitate the development of effective strategies for enhancing engagement and retention. Using clinical service data from a large naturalistic sample of adolescents, we examined whether client characteristics predict retention in outpatient alcohol and other drug (AOD) treatment. χ2 tests and multinomial logistic regressi...

The purpose of this study was to present descriptive information on the characteristics of 2,873 Medicare home health clients, to quantify systematically their patterns of service utilization and allowed charges during a total episode of care, and to clarify the bivariate associations between client characteristics and utilization. The model client was female, 75-84 years of age, living with a ...

This paper describes an approach for enabling remote database access from heterogeneous thin clients. DataX is a proxy-based architecture that supports disconnected operation by replicating a subset of the database on the mobile client, using a weak consistency criterion. It adapts data replication to device characteristics, link attributes and user preferences. It employs a per-device renderer...
