introduction: spiritual identity, defined as self-identification based on spirituality and spiritual experiences, has gained increasing attention during the past few years. the aim of this study was to assess several predictors and outcomes of spiritual identity based on a causal model. methods: for this purpose, parent and peer attachment were considered as exogenous variables, spiritual ident...

Dear editor-in-chief, The Future of Medical Education Journal The emergence of new theories of learning and education and a paradigm shift from being teacher-centered to student-centered alongside with advancement of novel communication technologies have set the grounds for modern human to use new methods of teaching-learning and free himself of the chains of time and place and keep on learning...

Online Social Networks (OSNs) are increasingly becoming one of the key media of communication over the Internet. The potential of these services as the basis to gather statistics and exploit information about user behavior is appealing and, as a consequence, the number of applications developed for these purposes has been soaring. At the same time, users are now willing to share information abo...

Let C be a plane convex body. For arbitrary points , denote by , n a b E  ab the Euclidean length of the line-segment . Let be a longest chord of C parallel to the line-segment . The relative distance between the points and is the ratio of the Euclidean distance between and b to the half of the Euclidean distance between and . In this note we prove the triangle inequality in with the relative ...

which should conform to basic physical intuition about distance. Thus, first, the only point y at distance 0 from a point x is y = x itself. Second, distance does not depend on direction: the distance from x to y is the same as the distance from y to x. Third, thinking that the distance from x to y should correspond to a shortest route of some kind from x to y, the distance from x to y should b...

Exercise 1. Show that distances between sets do not necessarily satisfy the triangle inequality. That is, it is possible that d(S1, S2) + d(S2, S3) > d(S1, S3) for some sets S1, S2 and S3. Exercise 2. Prove that d(x, y) ≥ d(S, x)− d(S, y) and thus d(x, y) ≥ |d(S, x)− d(S, y)|. Proof. Fix ε > 0. Let y′ ∈ S be such that d(y′, y) ≤ d(S, y) + ε (if S is a finite set, there is y′ ∈ S s.t. d(y, y′) =...
