The Geant4 Hadronic Verification Suite for the Cascade Energy Range

A Geant4 hadronic process verification suite has been designed to test and optimize Geant4 hadronic models in the cascade energy range. It focuses on quantities relevant to the LHC radiation environment and spallation source targets. The general structure of the suite is presented, including the user interface, stages of verification, management of experimental data, event generation, and comparison of results to data. Verification results for the newly released Binary cascade and Bertini cascade models are presented.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 5 pages, LaTeX, 3 eps figures.

How fair versus how long: An integrative theory‐based examination of procedural justice and procedural timeliness

Although studies have linked procedural justice to a range of positive attitudes and behaviors, the focus on justice has neglected other aspects of decision‐making procedures. We explore one of those neglected aspects: procedural timeliness—defined as the degree to which procedures are started and completed within an acceptable time frame. Do employees react to how long a procedure takes, not just how fair it seems to be? To explore that question, we examined the potential effects of procedural timeliness using six theories created to explain the benefits of procedural justice. This integrative theory‐based approach allowed us to explore whether “how long” had unique effects apart from “how fair.” The results of a three‐wave, two‐source field study showed that procedural timeliness had a significant indirect effect on citizenship behavior through many of the theory‐based mechanisms, even when controlling for procedural justice. A laboratory study then replicated those effects while distinguishing procedures that were too fast versus too slow. We discuss the implications of our results for research on fostering citizenship behavior and improving supervisors’ decision‐making procedures

Development of Integrated Programs for Aerospace-Vehicle Design (IPAD)

Integrated Programs for Aerospace Vehicle Design (IPAD) system design requirements are given. The information is based on the IPAD User Requirements Document (D6-IPAD-70013-D) and the Integrated Information Processing Requirements Document (D6-IPAD-70012-D). General information about IPAD and a list of the system design requirements that are to be satisfied by the IPAD system are given. The system design requirements definition is to be considered as a baseline definition of the IPAD system design requirements

Distribution of pollutants from a new paper plant in southern Lake Champlain, Vermont and New York

From November of 1973 to May of 1974, 15 arrays of sediment traps were placed along 33 km of southern Lake Champlain to sample the distribution of effluent from a large paper plant located on the western shore which had commenced operation in 1971. In the arrays located near the effluent diffuser pipeline as much as 2.3 cm of sediment accumulated, whereas elsewhere in the lake less than 1 cm accumulated. In the area of accelerated accumulation, sediments contained high concentrations of several components used in or derived from paper manufacturing. Values for kaolinite, expressed as the ratio of kaolinite to chlorite, for example, were as high as 1.4, anatase (TiO 2 ) concentrations were as high as 0.8%, organic carbon 8.7%, and phosphorus 254 µg/g; all were more abundant than in sediments collected in traps to the south or north. In surficial bottom sediments collected near each array organic carbon and phosphorus were also higher (4.2% and 127 µg/g respectively) near the diffuser than elsewhere. Thus, the new plant after three years of production measurably affected the composition of suspended sediment and surficial bottom sediment despite the construction and use of extensive facilities to reduce the flow of pollutants to the lake.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46764/1/254_2006_Article_BF02380502.pd

Fairness, envy, guilt and greed: building equity considerations into agency theory

In this article we examine the extent to which fairness considerations are salient to senior executives, and consider the implications for agency theory, tournament theory and the design of top-management incentives. We look for patterns in a unique data set of senior executive preferences and seek explanations for these patterns using a model of fairness first advanced by Fehr and Schmidt in 1999. We propose a number of amendments to Fehr and Schmidt’s model. We challenge some of the standard tenets of agency theory and tournament theory, demonstrating why equity considerations should be taken into account. We add to the growing literature on behavioural agency theory

Understanding Young Children's Health Beliefs and Diabetes Regimen Adherence

Previous studies of chronic illness management in children have focused mainly on parents' health beliefs. However, children's health beliefs also can be an important factor in predicting adherence. Indeed, children 6 to 10 years old spend most waking hours away from home, are under less parental supervision, and are becoming more responsible for their own care. The purpose of this study was to develop a pictorial, multi-item instrument to measure dimensions of the Health Belief Model (HBM) and self-efficacy (SE), designed specifically for children with diabetes, thus making it possible to examine both the parent's and child's health beliefs; to explore the relationship between their beliefs; and to examine the extent to which these beliefs are predictors of adherence and metabolic control.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68551/2/10.1177_014572179301900508.pd

Recent Developments And Validations in Geant4 Hadronic Physics

The Geant4 hadronic models cover the entire range of energies required by calorimeters in new and planned experiments. The extension and improvement of the elastic, cascade, parameterized and quark-gluon string models will be discussed. Such improvements include the extension to more particle types, a review and correction of cross sections, and a better treatment of energy and momentum conservation. Concurrent with this development has been a validation program which includes comparisons with double differential cross sections. An ongoing hadronic shower validation will also be discussed which includes the examination of longitudinal shower shapes and the performance of the above models as well as their interaction with electromagnetic processes such as multiple scattering

Using self-definition to predict the influence of procedural justice on organizational, interpersonal, and job/task-oriented citizenship behaviors

An integrative self-definition model is proposed to improve our understanding of how procedural justice affects different outcome modalities in organizational behavior. Specifically, it is examined whether the strength of different levels of self-definition (collective, relational, and individual) each uniquely interact with procedural justice to predict organizational, interpersonal, and job/task-oriented citizenship behaviors, respectively. Results from experimental and (both single and multisource) field data consistently revealed stronger procedural justice effects (1) on organizational-oriented citizenship behavior among those who define themselves strongly in terms of organizational characteristics, (2) on interpersonal-oriented citizenship behavior among those who define themselves strongly in terms of their interpersonal relationships, and (3) on job/task-oriented citizenship behavior among those who define themselves weakly in terms of their distinctiveness or uniqueness. We discuss the relevance of these results with respect to how employees can be motivated most effectively in organizational settings

Isospin-tracing: A probe of non-equilibrium in central heavy-ion collisions

Four different combinations of $^{96}_{44}$Ru and $^{96}_{40}$Zr nuclei, both as projectile and target, were investigated at the same bombarding energy of 400$A$ MeV using a $4 \pi$ detector. The degree of isospin mixing between projectile and target nucleons is mapped across a large portion of the phase space using two different isospin-tracer observables, the number of measured protons and the ${\rm t}/^{3}{\rm He}$ yield ratio. The experimental results show that the global equilibrium is not reached even in the most central collisions. Quantitative measures of stopping and mixing are extracted from the data. They are found to exhibit a quite strong sensitivity to the in-medium (n,n) cross section used in microscopic transport calculations.Comment: 4 pages RevTeX, 3 figures (ps files), submitted to Phys.
