This paper starts from the premise that private sector development is of crucial importance to the future development of MENA countries. It demonstrates the relative importance of various institutional constraints, in general, and impediments to dispute resolution, in particular, in reducing the competitiveness of private firms in the MENA region through by increasing transaction costs. It desc...

INTRODUCTION Research on diagnostic and formative assessment competencies during undergraduate medical training is scarce in Latin America. OBJECTIVE To assess the level of clinical competence of students at the beginning of their medical internship in a new curriculum. METHODS This was an observational cross-sectional study in UNAM Faculty of Medicine students in Mexico City: a formative a...

Many people have proposed definitions of ‘weak n-category’. Ten of them are presented here. Each definition is given in two pages, with a further two pages on what happens when n ≤ 2. The definitions can be read independently. Chatty bibliography follows.

OBJECTIVES To report the age-, sex-, and type-specific hip fracture incidence rates in Ecuador. A secondary objective was to examine hip fracture geographic variations in Latin America. METHODS The Anuario de Egresos Hospitalarios was analyzed to determine the number of persons aged 50 years or older hospitalized with a principal diagnosis of hip fracture (ICD-10 S72) in 2005. Census estimate...

A k_n Latin rectangle is a k_n matrix of entries from [1, 2, ..., n] such that no symbol occurs twice in any row or column. An intercalate is a 2_2 Latin subrectangle. Let N(R) be the number of intercalates in R, a randomly chosen k_n Latin rectangle. We obtain a number of results about the distribution of N(R) including its asymptotic expectation and a bound on the probability that N(R)=0. For...

in this paper we study the concept of latin-majorizati-on. geometrically this concept is different from other kinds of majorization in some aspects. since the set of all $x$s latin-majorized by a fixed $y$ is not convex, but, consists of :union: of finitely many convex sets. next, we hint to linear preservers of latin-majorization on $ mathbb{r}^{n}$ and ${m_{n,m}}$.

In this note we give two results. First, if a latin bitrade (T , T) is primary, thin, separated, and Aut(T ) acts regularly on T , then (T , T) may be derived from a group-based construction. Second, if a latin bitrade (T , T) has genus 0 then the disjoint mate T is unique and the autotopism group of T ⋄ is equal to the autotopism group of T.
