In this article, we seek to summarize current practice concerning situational judgment tests in personnel selection. We begin by describing the manner in which situational judgment tests are developed and examining the diverse ways in which situational items are presented and scored. We then offer speculation concerning constructs assessed by situational judgment tests as well as discuss the le...

Globalization and the rules it generates confront legal scholarship with a number of intricate issues. 1 One of these lies at the core of a hypothesis which has been

Although protocols vary from institution to institution in South Africa, there seem to be some common threads that raise persistent ethico-Iegal problems. Most institutions require that the patient's blood should be taken and be submitted for immediate testing along with the HCW's blood. This policy might lead to an HCW or patient being told in the middle of the night that he/she is HIV-positiv...

This paper describes how, based on a method originated by Raghavan and Roth and elaborated by Mavroidis and Roth, a systematic approach is defined in order to obtain and solve the input-output equations of any overconstrained mechanism. We show that the key to study overconstrained mechanisms lies in analyzing a certain matrix. We are using this matrix to prove overconstraint of special structu...

In this talk we discuss explicit constructions of sequences with optimal $L_2$ discrepancy and explicit constructions of point sets with optimal $L_q$ discrepancy for $1 < q < \infty$. In 1954 Roth proved a lower bound for the $L_2$ discrepancy of finite point sets in the unit cube of arbitrary dimension. Later various authors extended Roth's result to lower bounds also for the $L_q$ discrepanc...

We present in a unified way proofs of Roth’s theorem and an effective version of Mordell’s conjecture, using the ABC conjecture. We also show how certain stronger forms of the ABC conjecture give information about the type of approximation to an algebraic number.

This is a two part paper. The first part, written somewhat earlier, presented standard processes which cannot so easily be accommodated within what are presently considered as physical type realms. The second part further elaborates on that fact. In particular, it is argued that quantum superposition and entanglement may better be understood in extensions of what we usually consider as physical...

We give a quantitative version of Roth’s Theorem over an arbitrary number field, similar to that given by Bombieri and van der Poorten. Introduction. Let K/Q be a number field, with [K : Q] = d. Let MK be a complete set of inequivalent absolute values on K, normalized so that the absolute logarithmic height is given by h : K → [0,∞), h(x) = ∑

This article is a discussion about the proof of a classical theorem of Roth’s regarding the existence of three term arithmetic progressions in certain subsets of the integers. Before beginning with this task, however, we will take a brief look at the history and motivation behind Roth’s theorem. The questions and ideas surrounding this subject may have begun with a wonderful theorem due to van ...
