Conceptual frameworks and experimental design in simultaneous equations

hydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction

hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

WebML Application Frameworks: a Conceptual Tool for Enhancing Design Reuse

WebML is a high-level language for specifying the content structure of data-intensive Web applications, and the organization and presentation of such content through a hypertext structure. This paper concentrates on the conceptual design of structural schemas and hypertexts, which represents the core aspect of the WebML design process. In particular, the paper introduces a set of WebML skeleton...

Conceptual and Theoretical Frameworks for Organised Violence

Conceptual frameworks to illuminate and magnify.

CONTEXT In a recent study of the quality of reporting experimental studies in medical education, barely half the articles examined contained an explicit statement of the conceptual framework used. Conceptual frameworks represent ways of thinking about a problem or a study, or ways of representing how complex things work. They can come from theories, models or best practices. Conceptual framewor...

Disparities in defining disparities: statistical conceptual frameworks.

Motivated by the need to meaningfully implement the Institute of Medicine's (IOM's) definition of health care disparity, this paper proposes statistical frameworks that lay out explicitly the needed causal assumptions for defining disparity measures. Our key emphasis is that a scientifically defensible disparity measure must take into account the direction of the causal relationship between all...
