The Decision Support Systems (DSS) literature is in general agreement that use of DSS leads to individual and organizational change, but there is no consensus as to whether DSS and their designers serve as agents for directed or nondirected change. Researchers have proceeded from two different sets of premises, drawing different conclusions about the nature of DSS. This paper considers both vie...

Social psychology research on teams has shown that team performance improves when team members have a so-called shared mental model (SMM). We observe that a decision support system (DSS) and its user can be viewed as a team whose task is to make a (good) decision. Therefore we argue that it is important for good user-DSS team performance that they have a SMM. In this paper we make precise what ...

Dynamically substructured systems (DSS) are increasingly used by the dynamics testing community. DSS involves the physical testing of full size critical components in parallel with numerical testing of the remaining components. This has certain advantages over other testing methods [24]. However, the synchronization of the signals at the interface between the physical and numerical substructure...

As a subset of the Information systems (IS) discipline, Decision Support Systems (DSS) development research needs a broader conceptual lens in order to evaluate design qualities specific to DSS. This paper presents a development-oriented approach for evaluating DSS applications. Based on a design science mental model proposed by Peffers, Tuunanen, Rothenberger and Chatterjeea (2008), our study ...

Despite the growing need for decision support in the digital age, there has not been an adequate increase of interest in research and development in Decision Support Systems (DSSs). In our view, the vision for a new type of DSS should provision a tighter integration with the problem domain, and include implementation phase in addition to the traditional intelligence, design, and choice phases. ...

Cellobiose is produced from cellulose using specific bacterial enzymes, and is hydrolyzed into glucose by the enzymes cellobiosidase and cellulase. In this study, we examined the effects of cellobiose on colonic mucosal damage in a dextran sulfate sodium (DSS) colitis model. BALB/c mice were divided into two groups. In the first group, the mice were fed 3.5% DSS mixed with normal chow. In the s...

Decision support systems (DSS) have achieved considerable success in many areas of business activity. The type of semi-structured problem where DSS is successful frequently involves the management or configuration of vehicles or machines. While DSS has been used for human resource problems such as personnel scheduling, there have been fewer DSS applications in the area of personnel placement. T...

Aim. To investigate the effect of daikenchuto (TJ-100; DKT) for ulcerative colitis (UC) model mouse and assess its anti-inflammatory mechanisms. Methods. We evaluated the effects of DKT on dextran sulfate sodium- (DSS-) induced experimental colitis. First, we assessed the short-term effects of DKT using two groups: 5% DSS group and 5% DSS with DKT group. Colon length; histological scores; and i...

A theoretical framework for DSS research is developed in terms of the key elements of theory: domain boundaries, constructs, and relationships among constructs. Eight broad DSS constructs (environment, task, implementation strategy, DSS capability, DSS configuration, user, user behaviour, and performance) are identified. Based on a review of the literature, 17 relationships among these construc...

Reactive oxygen species (ROS) have been implicated as mediators of intestinal inflammation and carcinogenesis. Although green tea polyphenols (GTP) have anticancer property as antioxidants they also generate ROS in vitro. In this study, we investigated the modifying effects of GTP on dextran sulfate sodium (DSS)-induced acute colitis and on 1,2-dimethylhydrazine (DMH) and DSS-induced colon carc...
