This paper identifies novel approaches to future small and medium enterprise (SME) research from a review of articles, and then introduces the papers in this AJIS special section which evidence these approaches. More specifically, the paper makes an important contribution by reviewing 61 articles in high ranked IS journals (2000-2014) and introducing three new facets which are used to analyse research on SME adoption/use of IS (units of analysis, SME sizes and SME types) not considered in previous literature review studies. These facets provide thebasis for proposing various future research opportunities. The editorial then introduces the four papers in this special section covering the research theme on SMEs, and highlights the contributions they make using the three facets.

The importance of information systems/information technology (IS/IT) to healthcare organisations is being recognised today as paramount and critical in order to realise superior healthcare delivery. Successful assimilation of IS/IT, which is the central focus of this study, then becomes a key consideration in ensuring that IS/IT is appropriately and systematically deployed into a healthcare organisation. The key findings from this research indicate that there are people, process, technology and environment elements that should be considered as facilitators to the healthcare information systems (HIS) assimilation process, as well as barriers that the healthcare organisation should overcome throughout the entire assimilation process or at specific stages. This research, therefore, is not only topical but especially beneficial to management and administrators in the web of healthcare players as they grapple with trying to successfully assimilate HIS into their respective organisations. © 2014 by the Association for Information Systems.

BACKGROUND: Research in adults shows poor agreement between self-reported and objectively measured proximity to physical activity resources; however there is little such research in adolescents. This study assessed the level of agreement between self-reported and objective measures of distance to physical activity resources in adolescents; and whether perceived or actual distance was related to actual use and physical activity levels. METHODS: 110 New Zealand high school students (12-18 years) were asked the time (in minutes) it would take them to walk from their home to the nearest physical activity resource, and whether they had used it in the previous month. The distance from participants' homes to the nearest resource was measured using GIS. Physical activity was assessed with accelerometers. RESULTS: Agreement was poor, with weighted Kappa Indices ranging from 0.1 to 0.4. The facilities used most frequently were schools (90%), public parks (76%), and playing fields (74%). Closer location was associated with higher use of some facilities only. Moderate-to-vigorous activity levels were not associated with self-reported or measured distance. CONCLUSIONS: Agreement between perceived and measured access is poor among adolescents. Further research is needed to understand how individual and social factors interact with environmental factors and whether improving awareness improves use.

Nurses are the largest group of health-care professionals in hospitals providing 24-h care to patients. Hence, nurses are pivotal in coordinating and communicating patient care information in the complex network of health-care professionals, services, and other care processes. Further, surveillance and timely interventions by nurses impact quality of care, reduce errors, and decrease health-care costs. Information communication technologies (ICTs) provide the capabilities to support many aspects of nursing care. However, within the context of acute nursing care, there is a lack of integrated technology solutions to support the complex interactions associated with nursing activities and thereby the delivery of high-quality and safe care. Generally, to date, the literature reports low levels of acceptance of ICT solutions by nurses. To address this, the following discussion serves to examine nurses’ acceptance of an integrated point-of-care solution for acute nursing contexts. The ICT was specifically designed to be sensitive to nurses’ needs with the expectation that this will lead to high levels of user acceptance. An evaluation of the acceptability of the proposed solution is presented using unified theory of acceptance and use of technology (UTAUT). Through the UTAUT lens, initial reactions of the participating nurses were examined. The findings provided us with feedback to redesign the solution to better fit with the dynamics and complexity of nursing care. The study has implications for theory, including using UTAUT in health-care contexts, and for practice, including recommendations for the design and development of ICT solutions suitable for nursing contexts.

Cardiovascular disease (CVD) is the world's number one cause of mortality. Research in recent years has begun to illustrate a significant association between CVD and air pollution. As most of these studies employed traditional statistics, cross-sectional or meta-analysis methods, a study undertaken by the authors was designed to investigate how a geographical information system (GIS) could be used to develop a more efficient spatio-temporal method of analysis than the currently existing methods mainly based on statistical inference. Using Bangalore, India, as a case study, demographic, environmental and CVD mortality data was sought from the city. However, critical deficiencies in the quality of the environmental data and mortality records were identified and quantified. This paper discusses the shortcomings in the quality of mortality data, together with the development of a framework based on WHO guidelines to improve the defects, henceforth considerably improving data quality.

Flood inundation is a common natural disaster and a growing development challenge for many cities and thousands of small towns around the world. Soil features have frequently altered with the rapid development of urbanised regions, which has led to more frequent and longer duration of flooding in urban flood-prone regions. Thus, this paper presents a geographic information system (GIS)-based methodology for measuring and visualising the effects on urban flash floods generated by land-use changes over time. The measurement is formulated with a time series in order to perform a dynamic analysis. A catchment mesh is introduced into a hydrological model for reflecting the spatial layouts of infrastructure and structures over different construction periods. The Geelong Waurn Ponds campus of Deakin University is then selected as a case study. Based on GIS simulation and mapping technologies, this research illustrates the evolutionary process of flash floods. The paper then describes flood inundation for different built environments and presents a comparison by quantifying the flooding extents for infrastructure and structures. The results reveal that the GIS-based estimation model can examine urban flash floods in different development phases and identify the change of flooding extents in terms of land-use planning. This study will bring benefits to urban planners in raising awareness of flood impact and the approach proposed here could be used for flood mitigation through future urban planning.
