BACKGROUND AND OBJECTIVES Up to 30% of children who have concussion initially evaluated in the emergency department (ED) display delayed symptom resolution (DSR). Greater initial symptom severity may be an easily quantifiable predictor of DSR. We hypothesized that greater symptom severity immediately after injury increases the risk for DSR. METHODS We conducted a prospective longitudinal coho...

Although Design Science Research (DSR) is now an accepted approach to research in the Information Systems (IS) discipline, consensus on the methodology of DSR has yet to be achieved. Lack of a comprehensive and detailed methodology for Design Science Research (DSR) in the Information System (IS) discipline is a main issue. Prior research (the parent-study) aimed to remedy this situation and res...

A field experiment was conducted at Banaras Hindu University, Varanasi (2016-17) to evaluate the effect of crop establishment and weed management practices on productivity, economics resource-use efficiency direct-seeded rice (DSR). The treatments included three methods, viz. Zero-tillage-DSR+Sesbania co-culture (ZT-DSR+SCC), ZT-DSR+residue+Sesbania (ZT-DSR+R+SCC) Conventional till-DSR+Sesbania...

Since the use of design science research (DSR) gained momentum as a research approach in information systems (IS), the adoption of a DSR approach in postgraduate studies became more acceptable. This paper reflects on a study to investigate how a selection of IS doctoral students conducted their research and why they used DSR. The study focussed in particular on the topics of the theses, the art...

Design Science Research (DSR) has emerged as an important approach in Information Systems (IS) research. However, DSR is still in its genesis and has yet to achieve consensus on even the fundamentals, such as what methodology / approach to use for DSR. While there has been much effort to establish DSR methodologies, a complete, holistic and validated approach for the conduct of DSR to guide IS ...

There is broadening and increasingly unquestioned acceptance of design science research (DSR). Recently, DSR may have provided an important bridge for overcoming or bypassing artificial barriers to accepting the legitimacy of certain types of research, but in some cases it is not obvious how DSR actually contributed to the research. Perhaps it is time to retire the assumption that DSR is someho...

this paper presents a New Technique for Route Selection (NTRS) in DSR routing protocol to minimize the load by choosing the most stable path. Our proposal mechanism estimates the stability of the path by means of the received signal strength. Simulation results are used to draw conclusions regarding to use our proposed technique in route selection with DSR and compared it with the standard DSR ...

Die Durchführung von rigoroser und relevanter gestaltungsorientierter Forschung (engl. Design Science Research, DSR) gewinnt in der Wirtschaftsinformatik international an Akzeptanz und Bedeutung. Der vorliegende Beitrag verfolgt das Ziel, das Verständnis von DSR in der Wirtschaftsinformatik zu schärfen und DSR-Erfahrungen mit der Community zu teilen. Dafür wird ein Fallbeispiel, das ein umfangr...

Design Science Research (DSR) has sparked a renaissance of contributions to IS, but its rigor and value of DSR could be increased by expanding its scope beyond its engineering roots to bring all modes of scientific inquiry to bear – exploratory, theoretical , experimental, and applied science / engineering (AS/E). All DSR Cycle activities can be realized as instances of one or more of the four ...

Several papers have addressed the theory foundation of DSR. While researchers usually emphasize that the existence of such a knowledge base (KB) is essential for high quality design science research (DSR), opinions depart what kind of knowledge comprises such a knowledge base and which qualitative requirements apply regarding the knowledge leveraged. Some researchers demand that DSR is based on...
