Other Post Employment Benefits-The Other Elephant in the Room

The governments of the fifty states of the United States have made promises to past and present employees regarding retirement benefits-predominately pensions and healthcare coverage. The issues surrounding the pension obligations made to these employees have been well examined but the obligations due to promises of healthcare coverage have not received as much attention. There is great variance among the OPEB liability reported by the states. This study examines reasons for the variance. The future payment of healthcare obligations, like pensions, will put extreme stress on states in the future if the impact of these promises is not understood now. Understanding the influence healthcare assumptions have on the reported liabilitites is an important step to understanding these liabilities

A Bi-Exponential Repair Algorithm for Radiation-Induced Double-Strand Breaks: Application to Chromosome Aberrations

Chromosome aberrations (CAs) are one of the effects of radiation exposure and are used as a biomarker. A new simulation program, named RITCARD (Radiation induced tracks, chromosome aberrations, repair, and damage) was developed to simulate radiation-induced CA. RITCARD is used with the program RITRACKS (Relativistic Ion Tracks), which simulates the radiation tracks. The restitution kinetics algorithm presented here is a significant improvement over the one used in the first version. Simulations of radiation-induced CA were performed for several ion types and mixed irradiation fields. These simulations will be useful to help interpreting experiments of galactic cosmic rays (GCR) simulator

Distribution and Efficiency of Bacteriolysis in the Gut of Arenicola Marina and Three Additional Deposit Feeders

A simple technique was developed to measure the bacteriolytic activities of the digestive fluids of the deposit-feeding polychaete Arenicola marina. Lysis of a cultured environmental isolate, incubated with extracts of gut luminal contents, was monitored spectrophotometrically. Concurrent direct counts were used to verify cell lysis. The ability of extracts from 8 longitudinal sections of the gut to lyse the bacterium was monitored. The digestive ceca, anterior stomach, and posterior stomach regions exhibited high lytic activities, whereas bacteriolytic activities in all other regions of the gut were negligible. Similarly, extracts of surface sediments and fecal castings showed negligible lytic capabilities. The sharply limited distribution of lytic activity implicates the ceca as the source of bacteriolytic agent and suggests a true plug-flow system, with little axial mixing. Questions regarding the fate of lytic agents, which disappear abruptly posterior to the stomach, remain unanswered. Localization of lysis in the gut coupled with estimates of gut residence time permit the calculation that ingested bacteria are exposed to strong lytic activity for approximately 20 min. Incubation of in situ sediment samples with gut fluids corroborates the distributional findings of the in vitro work although the efficiency of lysis is much reduced, possibly due to exopolymer capsules and slimes of natural sedimentary bacteria. Cross-phyletic comparisons of bacteriolytic activities reveal both qualitative and quantitative differences. Much less demarcation of lytic activity is observed in the guts of a holothuroid (Caudina arenata) and a hemichordate (Stereobalanus canadensis), with a pattern more similar to that of A. marina observed in another polychaete, Amphitrite johnstoni. Quantitatively, the polychaetes showed higher levels of activity with rates in A. marina exceeding those of the hemichordate and holothuroid by more than 10-fold

Research on faith and health: new appoaches to old questions

Does religious faith influence health? Are religious practices associated with altered risks for morbidity or mortality? Do religious or spiritual individuals tend to enjoy better well-being or mental health across the lifespan? Does spiritual or religious involvement change the way individuals adapt to the demands of chronic illness? This volume brings together some of the leading investigators who have explored these intriguing questions. Though research is in its early phases, the chapters that follow review some of what we have learned and begin to trace the outlines of the many mysteries that remain

Connecting the time domain community with the Virtual Astronomical Observatory

The time domain has been identified as one of the most important areas of astronomical research for the next decade. The Virtual Observatory is in the vanguard with dedicated tools and services that enable and facilitate the discovery, dissemination and analysis of time domain data. These range in scope from rapid notifications of time-critical astronomical transients to annotating long-term variables with the latest modeling results. In this paper, we will review the prior art in these areas and focus on the capabilities that the VAO is bringing to bear in support of time domain science. In particular, we will focus on the issues involved with the heterogeneous collections of (ancillary) data associated with astronomical transients, and the time series characterization and classification tools required by the next generation of sky surveys, such as LSST and SKA.Comment: Submitted to Proceedings of SPIE Observatory Operations: Strategies, Processes and Systems IV, Amsterdam, 2012 July 2-

A Social Identity Perspective of Personality Differences between Fan and Non-Fan Identities

In three studies of fan communities we examined differences in the Big Five personality traits between fans’ personal and fan identities. In all three studies, self-identified furries completed a measure of the Big Five personality traits for both their personal and furry identity. In Study 1, furries were found to rate all five dimensions higher when referring to their furry (vs. personal) identity. In Study 2 we replicated these results and further found that the effect was not limited to furries: sport fans also reported different personality ratings when referring to their fan or personal identity. In Study 3, we again replicated the results while testing predictors of personality differences between salient identities. A path model showed that felt connection to one’s fandom identity predicted greater frequency of fandom identity salience, which, in turn, predicted greater personality disparity between identities. Taken together, the results suggest the role of the social identity perspective in explaining inconsistencies in personality

Study of nuclear recoils in liquid argon with monoenergetic neutrons

For the development of liquid argon dark matter detectors we assembled a setup in the laboratory to scatter neutrons on a small liquid argon target. The neutrons are produced mono-energetically (E_kin=2.45 MeV) by nuclear fusion in a deuterium plasma and are collimated onto a 3" liquid argon cell operating in single-phase mode (zero electric field). Organic liquid scintillators are used to tag scattered neutrons and to provide a time-of-flight measurement. The setup is designed to study light pulse shapes and scintillation yields from nuclear and electronic recoils as well as from {\alpha}-particles at working points relevant to dark matter searches. Liquid argon offers the possibility to scrutinise scintillation yields in noble liquids with respect to the populations of the two fundamental excimer states. Here we present experimental methods and first results from recent data towards such studies.Comment: 9 pages, 8 figures, proceedings of TAUP 2011, to be published in Journal of Physics: Conference Series (JCPS
