HERWIRI2.1: Electroweak Corrections for Hadron Scattering
We describe the program HERWIRI2.1, which implements order alpha-squared
photonic radiative corrections exponentiated at the amplitude level (initial
state, final state, and initial-final interference) and electroweak corrections
to the matrix element by generating events using the KK Monte Carlo to generate
the hard process, with quark initial states generated according to PDFs via an
LHAPDF interface. The events can be showered internally using HERWIG6.5 or
exported and showered using any desired external showering program. Some early
results are shown, including comparisons to HERWIG6.5 and HORACE 3.1.Comment: 9 pages, 12 figures. Presented by S. Yost at Loops and Legs in

Precision Electro-Weak and Hadronic Luminosity Calculations
We have used YFS Monte Carlo techniques to obtain per-mil level accuracy for
the Bhabha scattering cross section used in the luminosity monitor in
electro-weak scattering experiments. We will describe techniques for extending
these methods for use in the W production luminosity cross section for hadron
colliders.Comment: 8 pages (LaTex) with 5 figures (EPS). Presented by S.A. Yost at the

Analysis and Modification of Unprogrammed Reinforcement Contingencies in a Hospital for the Developmentally Disabled
36 leaves. Advisor: W. Scott WoodThe problem: To design a reliable observation system for monitoring of hospital attendants' on-ward interactions with hospital residents and to increase the rate of positive consequences delivered by the attendants for appropriate resident behaviors.
Procedure: An on-ward interaction recording system was developed and tested for reliability by camparing observation data with data obtained by trained independent observers. Following baseline observations, six hospital attendants were instructed to record their delivery of positive consequences to residents. If an attendant's rate of delivery of positive consequences increased during this self-monitoring ccndition, that attendant was subsequently returned to baseline observation conditions as a reversal procedure. If an attendant's rate of delivery of positive consequences had not increased during self-monitoring, that attendant was then given feedback and praised for increases in the rate of delivery of positive consequences delivered. All attendants in the self-monitoring-plus-praise condition were then returned to baseline conditions as a reversal procedure.
Findings: Results showed an inter-observer agreement of 80% for the on-ward observation system. Five of the six attendants increased their rates of delivery of positive consequences for appropriate resident behaviors when the attendants recorded their delivery of these positive consequences. The other attendant increased her rate when feedback and praise were added. Two of the five self-monitored attendants further increased their rates of positive consequences delivers when feedback and praise were added. Three of the six attendants increased their rates of successful attempts to change resident behaviors which paralleled their changes in positive consequences delivers. Conclusion: It was concluded that a reliable system for monitoring on-ward interactions between attendants and residents can be developed and that self-monitoring procedures can be used effectively with attendants to increase the rates of positive consequences delivered to residents for appropriate behavior. Recommendations: Further research would include the self-monitoring of other interaction behaviors specified in the current interaction analysis system. Longer periods of implementation may increase the effects of the self-monitoring procedure. More extensive training and feedback might increase inter-observer agreement with the interaction analysis system
Understanding the effects of violent video games on violent crime
Psychological studies invariably find a positive relationship between violent video game play and aggression. However, these studies cannot account for either aggressive effects of alternative activities video game playing substitutes for or the possible selection of relatively violent people into playing violent video games. That is, they lack external validity. We investigate the relationship between the prevalence of violent video games and violent crimes. Our results are consistent with two opposing effects. First, they support the behavioral effects as in the psychological studies. Second, they suggest a larger voluntary incapacitation effect in which playing either violent or non-violent games decrease crimes. Overall, violent video games lead to decreases in violent crime. --Video Games,Violence,Crime
(Chloromethyl)pentacarbonylmanganese(I): a crystal structure with a non-crystallographic centre of symmetry
There are two molecules in the asymmetric unit of the P2â/c unit cell of ClCHâMn(CO)â
, the first halomethyl complex of manganese to be structurally determined. The molecules are crystallographically independent, despite an apparent local centre of symmetry. The average bond parameters include MnâCalkyl 2.128(8) Ă

and MnâCâCl 116.4(4)
Treatment Techniques for Children, Teens, and Adults with Cluttering
AbstractDue to the lack of research regarding the efficacy of treatment approaches to cluttering, speech language the rapists (SLTs) are lacking in information regarding how to approach cluttering clients. The purpose of this presentation is to present a new view of examining evidence-based techniques for treating cluttering in children and adults. Through interactive discussion, methods for managing children, teens, and adults with cluttering will be presented. Assessment and treatment principles will be covered. Specific activities for increasing effective communication in a variety of clients and the evidence base to these activities will be presented. After attending this seminar, SLTs should be able to: 1) state three principles of cluttering assessment; 2) state three principles of cluttering treatment; 3) state three sources of literature establishing evidence base of treatment methods; 4) state three activities to address cluttering in children, teens, and adults with cluttering. Data gathered during actual treatment sessions will be presented in case study format. Overcoming obstacles in managing clients with cluttering using evidenced-based approaches a will be discussed
