Organisational arrangements have long been recognised as a critical enabler and fundamental component of Spatial Data Infrastructure (SDI). More recently, the term “governance” has become increasingly used to refer to aspects of institutional frameworks that support SDI. However, given the polysemous nature of the term and the evolving nature of approaches to implementing SDI, it not clear exac...

This paper aims to introduce and discuss six challenges and issues facing the development of SDIs which will be able to meet the sustainable development objectives of society. These issues and challenges include: SDI to facilitate spatially enabled government Role of government, private and academic sectors Development of SDI vision, mission and road map – where are we heading? SDI to facilitat...

People have always played an important role in SDI research. SDI researchers discuss in their papers the role of people explicitly or refer to people implicitly and from different angles. For example, they view people as users of SDI, as evaluators, as learners of SDI, as champions driving development, among others. In this article, we conduct an interpretive analysis of 142 peer-reviewed artic...

This paper presents the Multi-view assessment of SDI status in the Republic of Kosovo performed in 2007 and in 2010. The main objective of this research was to assess the SDI of Kosovo and to define the driving forces needed to support SDI strategy development. The research assesses the status of SDI implementation of Kosovo using SDI readiness Index (Delgado et al., 2005); INSPIRE State of Pla...

The successful implementation of the next generation of spatial data infrastructures (SDIs) will, in part, depend on the ability of SDI program coordinators to comprehend and report on the success or failure levels of the previous generations of SDIs. This is important from both a funding and an effectiveness perspective. From an effectiveness point of view, the performance of a system can only...

OBJECTIVE To examine long-term organ damage and safety following treatment with belimumab plus standard of care (SoC) in patients with systemic lupus erythematosus (SLE). METHODS Pooled data were examined from two ongoing open-label studies that enrolled patients who completed BLISS-52 or BLISS-76. Patients received belimumab every four weeks plus SoC. SLICC Damage Index (SDI) values were ass...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

Background LV intraventricular dyssynchrony is commonly assessed by systolic dyssynchrony index (SDI), which is defined by the dispersion of time of minimum regional cavity volume. Several studies have reported conflicting results on cardiac resynchronization therapy (CRT) responses based on SDI values. In this study, we aim to characterise SDI distributions in asymptomatic patients and to anal...

Gary A. Clark Research Agricultural Engineer Subsurface drip irrigation (SDI) systems deliver water to the root zone of crops using polyethylene drip tubing that is permanently buried below the soil surface. In properly designed and operated systems, little or no wetting of the soil surface occurs, nor is there visual evidence of the system performance. Because SDI systems apply water different...

Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...
