An upper bound on a ratio of variances

Several processes may be monitored in terms of their variances relative to each other by the maximum ratio of variances. Based on the observed value an upper confidence bound for the population value is derived and tables are supplied for its implementation. Such bounds may be used when the experimenter wishes to establish that the variances are "not too different". The usual testing of variances for equality is noticed to be inappropriate in such cases.     

COMPARISONS AND SELECTION OF TWO-PARAMETER EXPONENTIAL POPULATIONS

For two-parameter exponential populations with the same scale parameter (known or unknown) comparisons are made between the location parameters. This is done by constructing confidence intervals, which can then be used for selection procedures. Comparisons are made with a control, and with the (unknown) “best” or “worst” population. Emphasis is laid on finding approximations to the confidence so that calculations are simple and tables are not necessary. (Since we consider unequal sample sizes, tables for exact values would need to be extensive.)     

△-correct decision for location and scale parameters

In selecting t out of k populations, a △-correct decision is said to be made if the smallest location parameter for the selected populations is not more than △ below the largest location parameter for the non-selected populations. (For seal? parameters there is a similar definition in terms of ratio3.) The minimum probability of △-correct decision over the entire parameter pace is shown to be equal to the minimum probability of correct selection over a preference zone determined by △.     

Global Studies—The Handmaiden of Neoliberalism?

Abstract

The field of global studies has gained momentum over the past 20 years and today occupies a significant presence within many universities. As a result, there is now a burgeoning array of institutional support for global studies scholarship. Perhaps not surprisingly, concurrent to such institution-building there has been a spate of essays engaged with the question ‘what is global studies?’ that have promoted lively debate and commentary. In this essay, I ask a rather different question which is ‘who gets to define global studies, and what is at stake in these kinds of delineating efforts?’ I argue that debate about global studies demands the inclusion of multiple voices and perspectives from around the world. I conclude by urging global studies scholars to be deliberately conscious of their taken-for-granted assumptions with respect to power and the related capacity to speak for others from the global south and east who are largely still absent in defining this new field of inquiry.     

Media and the Israeli disability rights legislation: progress or mixed and contradictory images?

This article reviews and analyzes disability rights conceptualization and policy as reflected in the Israeli media after the enactment of the Equal Rights for Persons with Disabilities Law of 1998. Media coverage is examined through review of studies conducted on the subject in Israel. A comprehensive review of the research literature reveals a discrepancy between the purposes of anti‐discrimination legislation and policy and media reflections of disability, in which portrayal is primarily via a deviance lens. The discussion is based on the analysis of universal genesis of negative perceptions of disability, as well as on particularized culture bound meaning of disability within the Israeli symbolic framework.
