BACKGROUND The Canadian health system is undergoing reform. Over the past decade a prominent trend has been creation of health regions. This structural shift is concurrent with a greater emphasis on population health and the broad determinants of health. In parallel, there is a movement toward more intersectoral collaboration (i.e., collaboration between diverse segments of the health system, a...
We examined exposure to Internet pornography before the age of 18, as reported by college students (n = 563), via an online survey. Ninety-three percent of boys and 62% of girls were exposed to online pornography during adolescence. Exposure prior to age 13 was relatively uncommon. Boys were more likely to be exposed at an earlier age, to see more images, to see more extreme images (e.g., rape,...
In India, 70-80% population of the country depends directly or indirectly to farming. So this field is very much important for research and the concept of contract farming is more important for farmers and other persons who are joined with this. There are so many models of contract farming and many of them are explained by authors in this paper. Many advantages and issues related to contract fa...
This paper is motivated by R. H. Bruck’s paper[3], in which he proved that the existence of cyclic projective plane of order n ≡ 1 (mod 3) implies that of a non-planar difference set of the same order by proving that such a cyclic projective plane admits a regular non-Abelian automorphism group using n as a multiplier. In this paper we will discuss in detail the possibility of using multipliers...
The objective of this study was to learn about the production of nursing knowledge in Brazil associated with the clinic theme. This is a qualitative study performed by means of an integrative review. Data collection was performed on the SciELO database using the keywords nursing and clinic, present in the abstracts of articles. It was found that the clinic is seen as an instrument used to estab...
Comparison of protein structures can reveal distant evolutionary relationships that would not be detected by sequence information alone. This helps to infer functional properties. In recent years, many methods for pairwise protein structure alignment have been proposed and are now available on the World Wide Web. Although these methods have made it possible to compare all available protein stru...
We study the following Maker/Breaker game. Maker and Breaker take turns in choosing vertices from a given n-uniform hypergraph F , with Maker going first. Maker’s goal is to completely occupy a hyperedge and Breaker tries to avoid this. Beck conjectures that if the maximum neighborhood size of F is at most 2 then Breaker has a winning strategy. We disprove this conjecture by establishing an n-u...
