A data transformation recently used by Stone and Hollenbeck (1989) is based on a faulty premise and should not be considered in future analyses. Specifically, these authors mistakenly equate the homoscedasticity assumption in regression analysis with the notion that subgroup variances need to be equal. We demonstrate that subgroup variances in regression can be legitimately different, owing to ...

Goals are central to current treatments of work motivation, and goal commitment is a critical construct in understanding the relationship between goals and performance. Inconsistency in the measurement of goal commitment hindered early research in this area but the nine-item, self-report scale developed by Hollenbeck, Williams, and Klein (1989b), and derivatives of that scale, have become the m...

\begin{abstract} In this paper we address the problem of finding best constants in inequalities form: $$ \|\big(|P_+f|^s+|P_-f|^s\big)^{\frac{1}{s}}\|_{L^p({\mathbb{T}})}\leq A_{p,s} \|f\|_{L^p({\mathbb{T}})},$$ where $P_+f$ and $P_-f$ denote analytic co-analytic projection a complex-valued function $f \in L^p({\mathbb{T}}),$ for $p \geq 2$ all $s>0$, thus proving Hollenbeck-Verbitsky conjectur...

This document describes an Extensible Provisioning Protocol (EPP) extension mapping for the management of Domain Name System (DNS) domain names subject to "grace period" policies defined by the Internet Corporation for Assigned Names and Numbers (ICANN). Grace period policies exist to allow protocol actions to be reversed or otherwise revoked during a short period of time after the protocol act...

We introduce a point process model for inter-gang violence driven by retaliatory behavior. For this purpose we use a coupled system of state-dependent jump stochastic differential equations to model the conditional intensities of the directed network of gang rivalries. The system admits an exact simulation strategy based upon Poisson thinning. The model produces a wide variety of transient or s...

Kenny Nguyen is a junior majoring in neurobiology and physiology and minoring in psychology at Purdue University. He has been working in the Hollenbeck Lab since 2015, studying the degeneration of mitochondria in neurons and their implications in Parkinson’s disease. For the summer of 2015, he was selected as a Summer Undergraduate Research Fellowship (SURF) intern, and he received the William ...

I appreciate the secretarial assistance of Claire Vogelsong and Ellen Maloney with this paper. I would also like to thank Chuck Johnson, Kevin Hollenbeck and Bridget Timmeney for helpful conversations about this paper, and Craig Schreuder for help in getting information on the JTPA performance system. Preparation of this paper was funded in part by the Minnesota Department of Human Services. An...
