Cultural values can be important determinants of academic authors' rhetorical behavior. In particular, cultural characteristics such as uncertainty avoidance, power distance, and individualism/collectivism may a¤ect the ways authors express their certainty and commitment to their claims and appeal to group solidarity and communal opinion with a view to soliciting readers' acceptance of claims and community consensus.This paper aims to illustrate the ways such cultural characteristics differentiate the degree of certainty and conviction to claims expressed by native speakers of English (NSE) and native speakers of Greek (NSG) in research articles from the fields of electronic and electrical, and chemical engineering. Three sets of data are analyzed: research articles written by NSE, NSG in English and NSG in Greek, a total of 49, published in journals and conference proceedings.The findings indicate that Greek authors appear a great deal more certain and committed to their claims than native English speaking authors. This is shown to be a result of the high uncertainty avoidance, high power distance, and collective values that characterize Greek society.

SUMMARYPower assignment schemes are man-made methods to enhance the capture e!ect of radio communications. In a previous study, Wen and Yang investigated the combined capture e!ect of the "xed power assignment scheme, Rayleigh fading, and near}far e!ect on the performance of packet radios. The performance analysis was limited to an in"nite population environment. This assumption is reasonable for a conventional packet radio system with a vast service area. However, for a cellular mobile system, a "nite population model should be used. In this paper, we analyse the combined natural and man-made capture e!ect on the performance of a cellular system with "nite population in each cell. A random power assignment scheme is adopted to produce the man-made capture. The system throughput and delay are carried out by a Markov model. Some numerical calculations are used to demonstrate the degree of performance improvement.

“…W HEN CALCULATING an error rate or the probability of flagging an erasure in fading channels [1], most thresholding schemes can be reduced to the evaluation of a quadratic form in Gaussian variates. For the special case of Rayleigh fading, the complex Gaussian variates are zero mean, and the characteristic function of the thresholded variable is given by [2] (1)…”

This letter presents a new computational tool for use in general fading channel analyses when the detection scheme can be expressed as a quadratic form in zero-mean complex Gaussian random variables. We develop a simple numerical algorithm which is capable of inverting a characteristic function consisting of both simple and multiple poles. The approach benefits from the inherent symmetry in the residue calculations and uses the well-known Vandermonde matrix in order to take advantage of this symmetry. It is numerically stable, eliminates singularities, and circumvents the need for differentiation.
