The information technology (IT) marketplace is shaped by new kinds of specialist industry analysts that link technology supply and use through offering a commodified form of knowledge and advice. We focus on the work of one such organisation, the Gartner Group, and with how it produces a market analysis tool called the ‘Magic Quadrant’. Widely circulated amongst the IT community, the device com...

Petrov (1996) proved the connection between general moment conditions and the applicability of the strong law of large numbers to a sequence of pairwise independent and identically distributed random variables. This note examines this connection to a sequence of pairwise negative quadrant dependent (NQD) and identically distributed random variables. As a consequence of the main theorem ...

For a sequence of pairwise negative quadrant dependent random variables {Xn, n ≥ 1}, conditions are given under which normed and centered partial sums converge to 0 almost certainly. As special cases, new results are obtained for weighted sums { ∑n j=1 ajXj , n ≥ 1} where {an, n ≥ 1} is a sequence of positive constants and the {Xn, n ≥ 1} are also identically distributed. A result of Matu la [1...

in this paper, we generalize some results of chandra and goswami [4] for pairwise negatively dependent random variables (henceforth r.v.’s). furthermore, we give baum and katz’s [1] type results on estimate for the rate of convergence in these laws.

with an occurrence of 7%, appendicitis is one of the most common abdominal emergencies requiring surgery. since the variation in positions and length of the appendix may produce varying symptoms and signs which mimic other diseases, having knowledge of the variations in the position of the appendix is of significant importance. here, we present a 77-year-old man with acute appendicitis presenti...
