• 106 unique concepts identified • 13 (12%) of were common to both clinicians. • Including the descendants, the intersection was just over 47%. We believe this is a more useful measure of the intersection, since including a parent and child concept deserves much less of a penalty than including entirely incorrect concepts. • GF selected 36 concepts which EA did not including descendants only ad...

Exact integer concepts are fundamental to a wide array of human activities, but their origins are obscure. Some have proposed that children are endowed with a system of natural number concepts, whereas others have argued that children construct these concepts by mastering verbal counting or other numeric symbols. This debate remains unresolved, because it is difficult to test children's mastery...

Generalizability (G) theory is a statistical theory for evaluating the dependability (or reliability) of behavioral measurements (Cronbach, Gleser, Nanda, & Rajaratnam, 1972; see also Brennan, 2001; Shavelson & Webb, 1991). G theory permits the researcher to address such questions as: Is the sampling of tasks or judges the major source of measurement error? Can I improve the reliability of the ...

Ogilvie syndrome, or acute colonic pseudo-obstruction, is a severe distension of the colon caused by decreased large bowel motility in the absence of a mechanical obstruction. It can be a consequence of medical treatment such as with clozapine. An 82-year-old male with Alzheimer disease under treatment with antipsychotics (clozapine) was admitted with abdominal distension and constipation. On e...

urvival analysis is seldom used in studies of the S of musculoskeletal therapy. Most clinical studies of musculoskeletal therapy use parametric statistical methods such as analysis of variance (ANOVA) to illustrate the effects of treatment on outcomes. Nonparametric techniques of analysis such as survival analysis are less frequently used. Survival analysis has a number of advantages that make ...

In elementary physics, in order to describe the motion of a physical system, a few quantities need to be specified. In 1833, Irish mathematician Hamilton proposed a new formalism of physics. Given a physical system, two sets of first order differential equations can capture all the information. With the aid of the mathematical concept of manifolds, which was developed later, Hamiltonian formali...

Since the turn of the 19 th and 20 th centuries when systematic research on antique Greek mathematics began, the general tone of historiographical work in the field has been dominated by the so-called internalist attitude. H.G. Zeuthen, P. Tannery and others initiated a research tradition whose goal is to reconstruct the mathematical development of the minus 5 th and 4 th century Greece by prov...
