Perceived Parental Acceptance‐Rejection and Psychological Adjustment: A Meta‐Analysis of Cross‐Cultural and Intracultural Studies

Meta‐analytic procedures were used to pool information from 43 studies worldwide to test one of the major postulates of parental acceptance‐rejection theory (PARTheory). Specifically, using child and adult versions of the Parental Acceptance‐Rejection Questionnaire (PARQ) and the Personality Assessment Questionnaire (PAQ), these studies allowed us to assess the claim within PARTheory's personality subtheory that perceived parental acceptance‐rejection is associated universally with a specific form of psychological (mal)adjustment among children and adults, regardless of differences in gender, race, geography, language, or culture. Results of the analysis showed that the predicted relation emerged without exception in all studies. The mean weighted effect sizes across the full range of sociocultural and ethnic groups studied were r= .51 for children and r= .46 for adults. Analysis of fail safe N showed that 3,433 additional studies, all with nonsignificant results, would be required to disconfirm the pancultural association between the PARQ and PAQ among children; 941 such studies would be required to disconfirm this relation among adults.     

Using Econometric Models for Intrafirm Equity Salary Adjustments

This paper addresses the question of how econometric models can provide guidance on the means by which intrafirm discriminatory gender salary differences may be eliminated and how much each injured party should receive. Equity pay adjustment algorithms are developed that incorporate constraints dictated by practical considerations and the legal environment. Bounding salary adjustments from below, while holding constant the aggregate estimated equity salary adjustment, can redistribute compensatory adjustments away from the most underpaid to the most overpaid members of the injured class. Empirical examples are provided for a sample of faculty at a Research I university and a sample of employees of a state-wide supermarket chain.     

Knowledge acquisition for a supportive user interface for correspondence analysis

We studied the way in which experienced statisticians handle the output of a correspondence analysis program, in order to investigate the possibility of computerized support for the interpretation of complex output from statistical software. Four experts participated in this study, all with experience in consultation and with a high level of theoretical knowledge on the subject. In ‘thinking-aloud sessions' they tried to reach conclusions from two forms of output (first without and then with indication of the meaning of variables). We present results on rule-based reasoning by the experts. Suggestions are given for the application of these results in the construction of an intelligent user interface for correspondence analysis.     

Aliternative methods for estimating long-run responses with applications to australian import demand

This paper compares and contrasts a number of single-equation and systems estimators of long-run responses with application to a three-variable import demand model. Two variants of Box and Tiao's (1977) canonical estimator are developed and associated tests for the number of cointegrating vectors are introduced. A simulation study indicates that, while both Box-Tiao estimators have empirical distributions with fatter tails than the normal, there is evidence that the incidence of extreme values is even greater with Johansen's (1988) ML procedure.     

A Dimensional CLT for Non-Central Wilks' Lambda in Multivariate Analysis

Abstract.  We consider the non-central distribution of the classical Wilks' lambda statistic for testing the general linear hypothesis in MANOVA. We prove that as the dimension of the observation vector goes to infinity, Wilks' lambda obeys a central limit theorem under simple growth conditions on the non-centrality matrix. In one case we also prove a stronger result: the saddlepoint cumulative distribution function (CDF) approximation for the standardized version of Wilks' lambda converges uniformly on compact sets to the standard normal CDF. These theoretical results go some way towards explaining why saddlepoint approximations to the distribution of Wilks' lambda retain excellent accuracy in high-dimensional cases.     

A Matrix-Based Approach to Uncertainty and Sensitivity Analysis for Fault Trees1

System unavailabilities for large complex systems such as nuclear power plants are often evaluated through use of fault tree analysis. The system unavailability is obtained from a Boolean representation of a system fault tree. Even after truncation of higher order terms these expressions can be quite large, involving thousands of terms. A general matrix notation is proposed for the representation of Boolean expressions which facilitates uncertainty and sensitivity analysis calculations.
