Calculating both EVA and DEA indices is an effective way to comprehensive performance estimation. Russian market is full of differences between largest companies which influence their operation ...results. Some of them have more refinement facilities, other differ in export share or capital structure. There are plenty factors which we determined at the first stage of this research to compare those companies. Though, not all of them can really explain effectiveness changes such as EVA fluctuations or it’s decreasing trough 2014-2017 years at Russian market. This is possible with using a method suggested in this research.
This study aims to determine the effectiveness of the implementation of digital-based counseling in Central Bangka Regency. Respondents in this study were 335 people consisting of farmers and ...agricultural extension officers in 6 (six) districts in Central Bangka Regency. Data were collected through survey activities using a questionnaire. The data obtained were analyzed based on quantitative analysis using the Logit test. Based on the research results, it was found that all the variables studied were significantly related to the effectiveness of digital-based extension implementation in the Central Bangka Regency.
Analyzing the effectiveness of environmental impact assessment (EIA) is an important theme in EIA literature. Over the course of its development, the manifold term “effectiveness” has been delineated ...into four dimensions: Procedural, substantive, transactive, and normative. The present state of the art review covers not only studies about these concepts, but also the methods used to test them. It analyzes trends in 64 studies over a 20-year period. It is observed that results oriented research is more common than process oriented, but given the links between results and processes, procedural effectiveness remains the lens through which policy solutions are analyzed. Future research is recommended comparing developing and developed countries as well as studies focusing on subnational EIA systems. Serious gaps in the literature remain, such as developing methods to evaluate the direct impact of EIA on decision-making and how to integrate the pluralism found in the EIA process for sustainable ends. Reliance on perceptual survey and interview methods is common for substantive and normative effectiveness studies. The least studied dimension, transactive dimension, requires more study, specifically the cost efficiency of EIA. Promisingly, multidimensional studies are becoming more common that highlight linkages among these dimensions, although the nature of these linkages must be tested with more case studies
•State of the art covering 59 articles from 1996 to June 2016.•Reviews effectiveness concepts and methodologies used to explore them.•Major gaps and trends identified for four effectiveness dimensions.•Discusses multidimensional EIA studies as future of the research field.
The increase in treatment options creates an urgent need for comparative effectiveness research. Randomized, controlled trials comparing several treatments are usually not feasible, so other ...methodological approaches are needed. Meta-analyses provide summary estimates of treatment effects by combining data from many studies. However, an important drawback is that standard meta-analyses can compare only 2 interventions at a time. A new meta-analytic technique, called network meta-analysis (or multiple treatments meta-analysis or mixed-treatment comparison), allows assessment of the relative effectiveness of several interventions, synthesizing evidence across a network of randomized trials. Despite the growing prevalence and influence of network meta-analysis in many fields of medicine, several issues need to be addressed when constructing one to avoid conclusions that are inaccurate, invalid, or not clearly justified. This article explores the scope and limitations of network meta-analysis and offers advice on dealing with heterogeneity, inconsistency, and potential sources of bias in the available evidence to increase awareness among physicians about some of the challenges in interpretation.
The creation of a flexible, efficient, digitized, dependable and resilient power grid may well be the best route to increasing energy efficiency and security, as well as boosting the potential of ...renewable and distributed power sources. This book covers smart grids from A-Z, providing a complete treatment of the topic, covering both policy and technology, explaining the most recent innovations supporting its development, and clarifying how the smart grid can support the integration of renewable energy resources. Among the most important topics included are smart metering, renewable energy storage, plug-in hybrids, flexible demand response, strategies for offsetting intermittency issues, micro-grids for off-grid communities, and specific in-depth coverage of wind and solar power integration. The content draws lessons from an international panel of contributors, whose diverse experiences implementing smart grids will help to provide templates for success.
Provides critical information on the technological, design and policy issues that must be taken into account to ensure that the smart grid is implemented successfully
Demonstrates how smart grids can help utilities adhere to increased renewable portfolio standards
Provides examples of successful microgrid/smart metering projects from around the world that can act as templates for developers, operators and investors embarking upon similar projects
