Objective: The research objective was to test the hypothesis that corporate health and wellness contributed positively to South African companies’ financial results. Methods: The past share market performance of eligible healthy companies, based on Discovery’s Healthy Company Index, was tracked under three investment scenarios and compared with the market performance on the basis of the JSE FTS...

We consider a two-period portfolio problem with predictable assets returns. First-order (second-order) predictability means that an increase in the first period return yields a first-order (second-order) stochastically dominated shift in the distribution of the second period state prices. Mean reversion in stock returns, Bayesian learning, stochastic volatilities and stochastic interest rates (...

The Mini-Mental State (MMS) examination is a widely used screening test for dementia. The Modified Mini-Mental State (3MS) incorporates four added test items, more graded scoring, and some other minor changes. These modifications are designed to sample a broader variety of cognitive functions, cover a wider range of difficulty levels, and enhance the reliability and the validity of the scores. ...

This note first identifies a problem with the correctness of the RUN DAP for Conjunctive RAS, presented in the above paper,1 and it, subsequently, proceeds to the problem correction through an appropriate policy modification. More specifically, the first part of this note provides a counter example to the policy correctness (i.e., deadlock freedom of the controlled system) claimed in,1 while th...

Alternative definition: Then LG is the matrix with diagonal entries (LG)ii = di, and off-diagonal entries (LG)ij = −wij . Fact 1: The matrix L = LG is symmetric, non-diagonals entries are Lij = −wij , and its diagonal entries are Lii = di, where di = ∑ j:ij∈E wij is the degree of vertex i. It is useful to put these values in a diagonal matrixD = diag(d⃗). If G is unweighted, then L = D−A where A...

A very ’physical’ approach to this phenomenon can be made by making use of the linearity of Stokes equations and symmetries of the system. Here, we preform detailed calculations according to hints from Exercise 2.9 from the textbook [Kim & Karilla]. As the Stokes equations are linear in p and v, the pressure field p(r) can be written as a scalar product of a certain vector field P(r) and the po...

Previous Proposals and Problems Regarding the key question, two main streams of proposals are basically discernible. One stream maintained that both NP1 and NP2 are subject, trying to define various notions of subject: e.g., Yu (1909) called them big and small subject, Yoon (2003, 2007) major and grammatical subject, and Lee (2007) subject [Spec, RefP] and subject [Spec, TP], respectively. The ...

The brief time course of the calcium (Ca2+) channel opening combined with the molecular-level colocalization of Ca2+ channels and synaptic vesicles in presynaptic terminals predict sub-millisecond calcium concentration ([Ca2+]) transients of > or = 100 microM in the immediate vicinity of the vesicle. This [Ca2+] is much higher than some of the recent estimates for the equilibrium dissociation c...

Skillful writing is essential for professionals in science and medicine. Consequently, many undergraduate institutions have adjusted their curriculum to include in-depth instruction and practice in writing for students majoring in the sciences. In neuroscience, students are often asked to write a laboratory report in the style of a primary scientific article or a term paper structured like a re...
