INTRODUCTION Although men who have sex with men (MSM) in sub-Saharan Africa are at high risk for HIV acquisition, access to and quality of health and HIV services within this population are negatively affected by stigma and capacity within the health sector. A recently developed online MSM training programme (www.marps-africa.org) was shown to contribute to reductions in MSM prejudice among hea...

INTRODUCTION We conducted this study to evaluate the feasibility of implementing an internet-linked handheld computer procedure logging system in a critical care training program. METHODS Subspecialty trainees in the Interdepartmental Division of Critical Care at the University of Toronto received and were trained in the use of Palm handheld computers loaded with a customized program for logg...

The purpose was to determine the aerobic power (maximal oxygen uptake) and body composition of older track athletes after a 20-yr follow-up (T3). At 20 yr, 21 subjects [mean ages: 50.5 +/- 8.5 yr at initial evaluation (T1), 60.2 +/- 8.8 yr at 10-yr follow-up (T2), and 70.4 +/- 8.8 yr at 20-yr follow-up (T3)] were divided into three intensity groups: high (H; remained elite; n = 9); moderate (M;...

Given a continued fraction, we construct a certain function that is discontinuous at every rational number p/q. We call this discontinuity the “gap”. We then try to characterize the gap sizes, and find, to the first order, the size is 1/q2, and that, for higher orders, the gap appears to be perfectly ’randomly’ distributed, in that it is Cauchy-dense on the unit square, and thus, this function ...

We compare two families of continued fractions algorithms, the symmetrized Rosen algorithm and the Veech algorithm. Each of these algorithms expands real numbers in terms of certain algebraic integers. We give explicit models of the natural extension of the maps associated with these algorithms; prove that these natural extensions are in fact conjugate to the first return map of the geodesic fl...

The obvious approach for designing an algorithm around this fact is to use the Schwartz-Zippel test to see if (x − a) − (x − a) is the zero polynomial. However, this fails for two reasons. The first is that if n is not prime then Zn is not a field (which we assumed in our analysis of Schwartz-Zippel); the second is that the degree of the polynomial is n, which is the same as the cardinality of ...

The spatial learning abilities of young, middle-age, and senescent rats were investigated in two experiments using several versions of the Morris water maze task. In Experiment 1, Long-Evans hooded rats were trained to find a submerged escape platform hidden within the water maze. During this phase of testing, aged rats exhibited acquisition deficits compared with either young or middle-age sub...

Research shows that trust has a direct bearing on information systems usage patterns in a variety of contexts. Discussing the context of Knowledge Management Systems (KMS) training, this study suggests placing trust in a more background role as the facilitator. According to the view suggested, user involvement through learning is a key reason why employees after training decide voluntarily to c...

High level of sensitivity (1x10 DNA copies) and specificity of the developed test system for detection of the camelpox virus by polymerase chain reaction is a result of using CPV-f and CPV-r primers flanking the fragment sized 266 bp at the DNA site 2230 bp in length that encodes the B22R-like protein from CMLV185 to CMLV187. The test system has been tested using the strains of the camelpox vir...
