UNLABELLED Nurses' role and image as portrayed in young children's literature were described and analyzed. DESIGN AND METHODS A total of 30 children's books (pre-kindergarten through grade two audience) written in English were chosen using progressive theoretical sampling. Included were books, both fiction and non-fiction and with varying years of publication, that mentioned nurses and/or wer...

background: although many countries had improvement in heath system in last twenty years but expense of research and its difficulties does not allow managers to solve their problems by doing research. if we accept that biostatistics is one of the scientific tools for research, we imply that in all domains of health system research applying statistical techniques is essential. this study was per...

We look at arithmetic progressions on elliptic curves known as Huff curves. By an arithmetic progression on an elliptic curve, we mean that either the x or y-coordinates of a sequence of rational points on the curve form an arithmetic progression. Previous work has found arithmetic progressions on Weierstrass curves, quartic curves, Edwards curves, and genus 2 curves. We find an infinite number...

In practice, mathematics education is blocked (i.e., teaching one topic at a time; CCSS, 2010), but research generally promotes interleaving (i.e., teaching multiple topics together; Rohrer & Taylor, 2007). For example, fraction arithmetic is blocked with students being taught fraction addition before fraction multiplication. Since students often confuse fraction operations to produce arithmeti...

Continuing the work K. C. Das, I. Gutman, B. Furtula, On second geometric-arithmetic index of graphs, Iran. J. Math Chem., 1(2) (2010) 17-28, in this paper we present lower and upper bounds on the third geometric-arithmetic index GA3 and characterize the extremal graphs. Moreover, we give Nordhaus-Gaddum-type result for GA3.

In what case do you like reading so much? What about the type of the science and pseudoscience in social work practice book? The needs to read? Well, everybody has their own reason why should read some books. Mostly, it will relate to their necessity to get knowledge from the book and want to read just to get entertainment.

Background and Objectives: Clinicians in many countries increasingly use Personal Digital Assistant (PDA) as an assisting tool in clinical practice. The pattern of PDA usage by clinicians in Iran has not been characterized. This study explored the attitudes of Iranian residents and interns toward medical uses of PDA.   Methods: An interview-based qualitative study was carried out in 2011. A p...
