An Evaluation of the Usability of a Computerized Decision Support System for Nursing Homes

2011

SummaryBackground: Computerized decision support systems (CDSSs) have the potential to significantly improve the quality of nursing care of older people by enhancing the decision making of nursing personnel. Despite this potential, health care organizations have been slow to incorporate CDSSs into nursing home practices.Objective: This study describes facilitators and barriers that impact the ability of nursing personnel to effectively use a clinical CDSS for planning and treating pressure ulcers (PUs) and malnutrition and for following the suggested risk assessment guidelines for the care of nursing home residents.Methods: We employed a qualitative descriptive design using varied methods, …

Decision support for centralizing cargo at a Moroccan airport hub using stochastic multicriteria acceptability analysis

2010

The geographical location of Morocco places it at the heart of important sea, air, rail and motorway transport routes between four continents. In this study we evaluate different alternatives to centralize multimodal cargo at a Moroccan airport hub. The choice depends on different socio-economical criteria, the geographical location, and the environmental impacts. Some of the criteria can be measured quantitatively, while for others only qualitative assessment is feasible. Furthermore, significant uncertainty is present in both the criteria measurements and the preferences. We aided this decision process using Stochastic Multicriteria Acceptability Analysis (SMAA). SMAA is a method that all…

The complexity of finite model reasoning in description logics

2005

AbstractWe analyse the complexity of finite model reasoning in the description logic ALCQI, i.e., ALC augmented with qualifying number restrictions, inverse roles, and general TBoxes. It turns out that all relevant reasoning tasks such as concept satisfiability and ABox consistency are ExpTime-complete, regardless of whether the numbers in number restrictions are coded unarily or binarily. Thus, finite model reasoning with ALCQI is not harder than standard reasoning with ALCQI.

Information needs and uses: An analysis of the literature published in Spain, 1990–2004

2007

This article presents a descriptive analysis of works published in Spanish journals and of the papers of conferences held in Spain in the field of information needs and uses in the period 1990–2004 in order to determine if the change in approach described by Dervin and Nilan, among others, also occurred outside the English speaking world. An analysis of the characteristics of relevant publications in this field (by year, authorship, type of document, type of work, and means of publication) shows that although activity is increasing, information needs and uses have not yet become a well-established area. In addition, a study of the content characteristics (by type of user, methodology used, …

Design principles for learning analytics information systems in higher education

2020

This paper reports a design science research (DSR) study that develops, demonstrates and evaluates a set of design principles for information systems (IS) that utilise learning analytics to support learning and teaching in higher education. The initial set of design principles is created from theory-inspired conceptualisation based on the literature, and they are evaluated and revised through a DSR process of demonstration and evaluation. We evaluated the developed artefact in four courses with a total enrolment of 1,173 students. The developed design principles for learning analytics information systems (LAIS) to establish a foundation for further development and implementation of learning…

Tensions in Information System Artefacts: Explaining Land Information Systems’ Sub-optimal Impact in Indonesia

2017

Part 14: Current Issues; International audience; Despite the advancement of more integrated land information systems (LIS), conflicts and disputes over land in Indonesia remain. Our study seeks to explain this situation. Using an interpretive case study conducted in Eastern Indonesia and framed within the concepts of information system (IS) artefacts, we find that tensions within and between information, technology, and social artefacts help to explain the sub-optimal LIS impacts. Inconsistent information, unsuitable technology, and conflicting social arrangements are examples of such tensions. Unless the tensions are properly resolved, LIS use cannot fulfil its potential for more appropria…

Incremental Accumulation of Information Systems Design Theory

2021

This paper proposes an organizing device for accumulation of information systems (IS) design theory components within a study but also across research studies. The proposed framework enables actors to understand the relationship over time between search spaces of information systems design science theory (ISDT) development by one and the same or different actors. The proposition rests on the notion that ISDT development is an iterative and incremental process that often happens across different research studies. Finally, we argue that with the proposed framework, ISDT knowledge is more easily transferred and combined with the search processes.

Examining the Quality of Evolution Frameworks and Metamodeling Paradigms of Information Systems Development Methodologies

2011

Information systems development methodologies and associated CASE tools have been considered cornerstones for building quality into an information system. The construction and evaluation of methodologies are usually carried out by evaluation frameworks and metamodels, both considered as meta-methodologies. This chapter investigates and reviews representative metamodels and evaluation frameworks for assessing the capability of methodologies to contribute to high-quality outcomes. It presents a summary of their quality features, strengths, and weaknesses. The chapter ultimately leads to a comparison and discussion of the functional and formal quality properties that traditional meta-methodolo…
