BACKGROUND The use of alternative tobacco products (ATPs) has grown in popularity among Canadian youth. This study examined the association between a school-level characteristic (the senior student tobacco use rate) and the current use of manufactured cigarettes, little cigars or cigarillos, cigars, roll-your-own cigarettes, smokeless tobacco (SLT), and a hookah among junior students. METHODS...

BACKGROUND The purpose of this study was to investigate the diagnostic value of 3.0-T (1)H magnetic resonance spectroscopy ((1)H MRS) in primary malignant hepatic tumors and to compare the effects of (1)H MRS on the diagnostic accuracy of liver-occupying lesions between junior and experienced radiologists. METHODS This study included 50 healthy volunteers and 40 consecutive patients (50 lesio...

Notation. (u, v)G is the shortest path between u and v with u, v ∈ V (G) and (u, v)G ⊆ E(G). ‖(u, v)G‖ denotes the length of this path. We will omit the subscript when the context is obvious. Most of the time, we use paths as sets of edges. However, we will occasionally refer to the path’s vertex set; by that, we mean the set of vertices that are endpoints of members of the path. The ends (or e...

Joan Bosa: Classification of monoids. Applications to the Cuntz semigroup. The Cuntz semigroup W (A), in its classical format, fails to be a continuous functor. This shortcoming was remedied by Coward, Elliott and Ivanescu who, in 2008, introduced a new category (called Cu) and a semigroup attached to any C∗-algebra A (called Cu(A)), which belongs to Cu. The assignment A 7→ Cu(A) is now continu...

Although several studies described the experience of doctors in their first postgraduate years, few shed the light on the ethical issues encountered by them. These doctors face a broad range of 'everyday' ethical challenges, from breach of confidentiality to truth-telling or improper informed consent. The daily ethical issues faced by junior doctors are not as dramatic as the major issues learn...

Research collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers act...

The object of this study was to assess the ability of junior doctors in the accident and emergency department to detect electrocardiographic (ECG) abnormalities. The ECG's performed in this department were monitored over a 4 week period. The initial diagnosis by the accident and emergency doctor was compared with the report from the cardiologist on 126 ECG's which showed abnormalities. The erro...

The Junior Professor project has been in operation for ten years. It is a project in which elementary school children teach lessons in a college level class on computers in education. The project requires little in the way of funding, and only reasonable arrangements and effort to organize. The elementary school students have benefited substantially as have the college students and the universi...

The prevalence and characteristics of mentorship among junior faculty in clinician-scientist and clinician-educator tracks were evaluated. Comprehensive improvement strategies are needed.
