A basic guide for empirical environmental social science Ecology and Society
Cox, Michael; Environmental Studies Program, Dartmouth College; michael.e.cox@dartmouth.edu.
In this paper, I address a gap in the literature on environmental social science by providing a basic rubric for the conduct of empirical research in this interdisciplinary field. Current literature displays a healthy diversity of methods and techniques, but this has also been accompanied by a lack of consistency in the way in which research in this area is done. In part this can be seen as resulting from a lack in supporting texts that would provide a basis for this consistency. Although relevant methods texts do exist, these are not written with this type of research explicitly in mind, and so translating them to this field can be awkward. This paper is designed to fill this gap and enable more consistency in the conduct of empirical environmental social...

EFFECTS OF FOOD ASSISTANCE AND NUTRITION PROGRAMS ON NUTRITION AND HEALTH, VOLUME 1, RESEARCH DESIGN AgEcon
Hamilton, William L.; Rossi, Peter H..
This is the first of four reports in the "Nutrition and Health Outcome Study," which assesses the effects of USDA's food assistance and nutrition programs on nutrition and health outcomes. This report reviews the research designs available to evaluators for assessing the effect of USDA's food assistance and nutrition programs. The random assignment experiment is the "gold standard" design for such an evaluation. Where random assignment is impossible, quasi-experimental designs are used to infer what would have happened to program participants if the program had not existed. Eight types of quasi-experimental design are identified as having been used in evaluations of food assistance and nutrition programs, although none can guarantee unbiased estimates of...

Reporting on methods of subgroup analysis in clinical trials: a survey of four scientific journals BJMBR
Moreira Jr.,E.D.; Stein,Z.; Susser,E..
Results of subgroup analysis (SA) reported in randomized clinical trials (RCT) cannot be adequately interpreted without information about the methods used in the study design and the data analysis. Our aim was to show how often inaccurate or incomplete reports occur. First, we selected eight methodological aspects of SA on the basis of their importance to a reader in determining the confidence that should be placed in the author's conclusions regarding such analysis. Then, we reviewed the current practice of reporting these methodological aspects of SA in clinical trials in four leading journals, i.e., the New England Journal of Medicine, the Journal of the American Medical Association, the Lancet, and the American Journal of Public Health. Eight...

What is Published in Human Morphology?: Types of Designs and Levels of Evidence International Journal of Morphology
Suazo Galdames,Iván; Manterola D,Carlos.
Evidence-based medicine (EBM) employs the best available evidence in a particular time and context to solve specific clinical problems. This method of practicing medicine has been adopted by most of the disciplines involved in medical training; however, morphology appears to remain beyond this paradigm. The first step in evidence-based practice based on morphology is to recognize the types of studies being conducted with regard to morphology, followed by the assessment of the level of evidence that they provide, which is the purpose of this study. We designed a bibliometric study, in which journals in the Master Journal List of Thomson Reuters, selected using the keywords "Morphology" or "Anatomy," available between 2007 and 2008, with access to full text...
