Many countries throughout the world believe they can benefit both economically and environmentally from better management of their spatial data assets, enabling them to access and retrieve complete and consistent datasets in an easy and secure way. This has resulted in the development of the Spatial Data Infrastructure (SDI) concept at various political and/or administrative levels. The SDI con...
This study constructs a measure of socioeconomic development in Muslim countries based on Ibn Khaldun’s model development. It proposes composite index three dimensions, namely human empowerment, government and institution, economic growth, terms it as Khaldun-based (I-SDI). A total 13 indicators are selected to represent each dimension employed for construction the using an equal weighted metho...
BACKGROUND Left ventricular (LV) mechanical dyssynchrony (LVMD) has emerged as a therapeutic target using cardiac resynchronization therapy (CRT) in selected patients with chronic heart failure. Current methods used to evaluate LVMD are technically difficult and do not assess LVMD of the whole LV simultaneously. We developed and validated real-time 3D echocardiography (RT3DE) as a novel method ...
Stimulant-dependent individuals (SDI) have abnormal brain metabolism and structural changes involving dopaminergic target areas important for the processing of time. These individuals are also more impulsive and impaired in working memory and attention. The current study tested whether SDI show altered temporal processing in relation to impulsivity or impaired prefrontal cortex functioning. We ...
The paper argues that SDI can best be understood in terms of praxis more than as technological artefact. Because of the many different and often conflicting views of reality, interests and other values between the many heterogeneous actors that are involved, SDI development causes inevitably paradoxes and dilemmas. The paper assumes that SDI is context specific but also has the generic properti...
Spatial Data Infrastructure (SDI) is a concept that aids in discovering, sharing, and using geospatial data. Nevertheless, given the breadth of this concept, several ways of developing SDI have emerged. The International Cartographic Association (ICA) has proposed a formal model to describe SDIs irrespective of technologies and implementations by using three of the five viewpoints of the RMODP ...
OBJECTIVE To establish the prevalence of reduced bone mineral density (BMD) and fractures, and risk factors for fractures, in a cross sectional study of a large cohort of patients with systemic lupus erythematosus (SLE). METHODS All SLE patients willing to take part in the study had bone densitometry in 1999/2000 and completed a questionnaire on risk factors for osteoporosis and on drugs used...
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...
To quantify the effects of crown thinning on the water balance and growth of the stand and to analyze the ecophysiological modifications induced by canopy opening on individual tree water relations, we conducted a thinning experiment in a 43-year-old Quercus petraea stand by removing trees from the upper canopy level. Soil water content, rainfall interception, sap flow, leaf water potential and...
Recently, the number and intensity of hydrological droughts have been increasing; thus, it is necessary to identify respond them quickly. Since primary data in Lithuania are water levels, converting these into discharge takes additional time, there a need develop methodology or adapt analyze detect droughts. This paper examines concept standardized level index (SWLI) calculation, which based on...
