TL;DR: In this article, a new boundary condition rule was proposed to improve the power of unit root and KPSS tests by using recursive demeaning procedures that mitigate the effects of small sample autoregressive bias.
Abstract: HAC estimation commonly involves the use of prewhitening filters based on simple autoregressive models. In such applications, small sample bias in the estimation of autoregressive coefficients is transmitted to the recoloring filter, leading to HAC variance estimates that can be badly biased. The present paper provides an analysis of these issues using asymptotic expansions and simulations. The approach we recommend involves the use of recursive demeaning procedures that mitigate the effects of small sample autoregressive bias. Moreover, a commonly-used restriction rule on the prewhitening estimates (that first order autoregressive coefficient estimates, or largest eigenvalues, greater than 0.97 be replaced by 0.97) adversely interferes with the power of unit root and KPSS tests. We provide a new boundary condition rule that improves the size and power properties of these tests. Some illustrations are given of the effects of these adjustments on the size and power of KPSS testing. Using prewhitened HAC estimates and the new boundary condition rule, the KPSS test is consistent, in contrast to KPSS testing that uses conventional prewhitened HAC estimates (Lee, 1996).

TL;DR: The hypothesis that stability of self-esteem would moderate the predictive relationship between level ofSelf-esteem and depression was tested and results strongly supported this hypothesis.
Abstract: The hypothesis that stability of self-esteem would moderate the predictive relationship between level of self-esteem and depression was tested. Specifically, level of self-esteem was hypothesized to relate more strongly to subsequent depression for individuals with stable self-esteem than for individuals with unstable self-esteem. Results strongly supported this hypothesis. Implications for the relation between level of self-esteem and depression, and for the moderator variable approach to personality and prediction, are discussed.

01 Feb 1991TL;DR: The authors develop methodologies for the automatic selection of image features to be used to visually control the relative position and orientation (pose) between the end-effector of an eye-in-hand robot and a workpiece.
Abstract: The authors develop methodologies for the automatic selection of image features to be used to visually control the relative position and orientation (pose) between the end-effector of an eye-in-hand robot and a workpiece. A resolved motion rate control scheme is used to update the robot's pose based on the position of three features in the camera's image. The selection of these three features depends on a blend of image recognition and control criteria. The image recognition criteria include feature robustness, completeness, cost of feature extraction, and feature uniqueness. The control criteria include system observability, controllability, and sensitivity. A weighted criteria function is used to select the combination of image features that provides the best control of the end-effector of a general six-degrees-of-freedom manipulator. Both computer simulations and laboratory experiments on a PUMA robot arm were conducted to verify the performance of the feature-selection criteria. >

TL;DR: In this article, the authors review the criteria for seismic slip defined by Cowan and determine that they are too narrow, and conclude that seismic slip at rates in the range 10−4−101 ǫm/s is almost certainly dynamic.
