Models for two-way contingency tables

We derive a theoretical and parametrized form for a two-way contingency table by using matrix calculus and Kronecker products.     

On the recovery of intra- and interblock information in n-ary designs

This note presents an extension of Q-method of analysis for binary designs given by Rao (1956) to n-ary balanced and partially balanced block designs. Here a linked n-ary block (LNB) design is defined as the dual of balanced n-ary (BN) design. Having a note on Yates’ (1939, 1940) method of P-analysis, we further extend the expressions for binary linked block (LB) designs given by Rao (1956) to linked n-ary block (LNB) designs which admit easy estimation of parameters for these type of all n-ary designs.     

Asymptotic equivalence of the harrell-davis median estimator and the sample median

This paper presents an asymptotic equivalence result with a sharp rate of convergence forthe sample median and the Harrell-Davis median estimator. The consequences of this result are discussed.     

Response transformations in repeated measures and growth curve models

This article describes estimation and inference procedures for the parameters of the Box-Cox and foided-power transformations in repeated measures and growth curve models. Procedures for computing maximum likelihood estimates of the transformation and covariance parameters under several covanance structures (omnibus sphericity, local sphericity, and unstructured) are described. Lack of fit statistics and hypothesis tests for comparing these structures also are described. The procedures are illustrated on three data sets. Software for performing the analyses in the SAS System is described and is available from the authors.     

Transnational youth transitions: becoming adults between Vancouver and Hong Kong

In the context of the academic interest shown in the enduring transnationalism of contemporary migrants and in the modes of transitions to adulthood in different global settings, in this article we examine the transnational lives of adolescents moving between Vancouver (Canada) and Hong Kong. While there is a lot of literature on the parents' political and economic calculations, there is very little on how adolescents in these situations articulate their geographical sensibilities. We draw on three periods of fieldwork undertaken in 2002, 2008 and 2010 during which we employed a transnational methodology to interview young people in Vancouver and Hong Kong. We argue that becoming an adult involves a process in which, in their discussions about the geographical and emotional distance between themselves and their families, young people articulate their own complex emotions towards specific places in their transnational social field. Their families sporadically interrupt the adolescents' otherwise independent lives with fragmented modes of supervision. By examining the complex intentions and emotions behind circular migration from the perspective of transnational youth in a community of split families, we advance the discussion on transnational geographies, particularly of the family in the context of a flexible global economy.     

“The Battle of Many Names,or No Remorse”

This three‐act historical ethnodrama rereads the discourse surrounding Custer's Last Stand, arguably the most written‐about military event in American history. It compares and contrasts First Nation oral history accounts, official military records, and select painterly representations of the “Battle of Little Bighorn.” It asks if there was a real “last stand” or only a flawed grand narrative (see Denzin 2011).     

The role,power and influence of company chairs

This paper develops an analytical framework to depict the heterogeneity that characterises the role of board chair and demonstrate the potential variability in how chairs operate boards and exercise power and influence on strategy, control and resource related tasks at board level. Theories of power and influence, as applied to top management teams and boards of directors, are explicated within the context of contemporary governance practices that are establishing the role of the board chair as distinct to that of the chief executive officer. Specifically, the paper maps sources of power and varying contemporary chair practices, including chair nomenclature (i.e. executive vs. non-executive chairs), chair origin (insider vs. outsider) and chair time (full-time vs. part-time). A number of theoretical chair-power models emerge from this analysis and are subject to empirical analysis using data collected from 160 chairs of 500 FTSE-listed companies. Theoretically and empirically, the paper complements structural approaches to studying boards with attention to behaviour on boards. By linking board structure, board process and the exercise of influence, the study reveals both differences amongst chairs in how they run the board, but also that chairs’ differ in the influence they exert on board-related tasks. Full-time executive chairs exert their greatest influence in strategy and resource dependence tasks whereas part-time, non-executive chairs seem to exert more influence over monitoring and control tasks.     

Optimum spacings for the joint estimation and tests of hypothesis of location and scale parameters of the cauchy distribution

A simultaneous test for the location and scale parameters of the Cauchy distribution is considered based on selected order statistics.. It is shown that optimum spacings that maximise the Pitman ARE of the test coincide with that of the optimum spacings for the estimation problem.
