Developing the Conceptual and Methodological Framework for Discursive-institutional Analysis of Coastal Exclusive Space Production: with Special Reference to Critical Realism Perspective
Because of the limited capacity of coastal lands and conflicting interests among stakeholders for coastal resources, there are intensifying pressures to retain and provide more public access to the coast. Coastal gated communities have been developed increasingly in the middle shoreline of Caspian Sea in North of Iran. They are kind of exclusive space production as they restrict public access t...
متن کاملApplication of the development stages of a cluster randomized trial to a framework for evaluating complex health interventions
INTRODUCTION Trials of complex health interventions often pose difficult methodologic challenges. The objective of this paper is to assess the extent to which the various development steps of a cluster randomized trial to optimize antibiotic use in nursing homes are represented in a recently published framework for the design and evaluation of complex health interventions. In so doing, the util...
متن کاملEmpirical Power and Sample Size Calculations for Cluster-Randomized and Cluster-Randomized Crossover Studies
In recent years, the number of studies using a cluster-randomized design has grown dramatically. In addition, the cluster-randomized crossover design has been touted as a methodological advance that can increase efficiency of cluster-randomized studies in certain situations. While the cluster-randomized crossover trial has become a popular tool, standards of design, analysis, reporting and impl...
متن کاملA Toolbox for K-Centroids Cluster Analysis
A methodological and computational framework for centroid-based partitioning cluster analysis using arbitrary distance or similarity measures is presented. The power of highlevel statistical computing environments like R enables data analysts to easily try out various distance measures with only minimal programming effort. A new variant of centroid neighborhood graphs is introduced which gives ...
متن کاملMethodological issues of confounding in analytical epidemiologic studies
Background: Confounding can be thought of as mixing the effect of exposure on the risk of disease with a third factor which distorts the measure of association such as risk ratio or odds ratio. This bias arises because of complex functional relationship of confounder with both exposure and disease (outcome). In this article, we provided a conceptual framework review of confounding issues in epi...
