    Strange Fluctuations at RHIC

    Get PDF
    Robust statistical observables can be used to extract the novel isospin fluctuations from background contributions in K-short K-plus measurements in nuclear collisions. To illustrate how this can be done, we present new HIJING and UrQMD computations of these observables.Comment: 4 pages, 2 figures, talk at Quark Matter 200

    Charmonium Suppression by Comover Scattering in Pb+Pb Collisions

    Get PDF
    The first reports of ψ\psi and ψ′\psi' production from experiment NA50 at the CERN SPS are compared to predictions based on a hadronic model of charmonium suppression. Data on centrality dependence and total cross sections are in good accord with these predictions.Comment: 9 pages, latex, 6 figures, epsf, figure added and text modified to clarify result

    Corporate Social Responsibility at Gap: An Interview with Eva Sage-Gavin

    Get PDF
    Gap Inc. is one of the world\u27s largest specialty retailers, with more than 3,000 stores and fiscal 2005 revenues of $16 billion. They operate four of the most recognized apparel brands in the world — Gap, Banana Republic, Old Navy and Forth & Towne. According to the company website “At Gap Inc., social responsibility isn\u27t just a catchphrase or a feel good initiative. It\u27s a reflection of who we are and how we operate as a company. To us, being socially responsible means striving to embed our values and ethics into everything we do — from how we run our business, to how we treat our employees, to how we impact the communities where we do business. In 2003 Gap Inc. was the first retailer to release a social responsibility report, offering a comprehensive overview of their approach to social responsibility. The report was broadly lauded for its willingness to be open and honest about both the successes and failures in this arena. In fact, this report won Business Ethics magazine\u27s Social Reporting Award for unprecedented honesty in reporting on factory conditions. Their 2004 Social Responsibility Report continued that discussion and provided new information on their progress, challenges, and new initiatives. Eva Sage-Gavin is Executive Vice President, Human Resources and Corporate Communications, of Gap Inc. In her role as Chief People Officer, she sets the strategy for the company\u27s communications and human resources operations worldwide, including staffing, diversity, rewards, recognition, employee benefits, learning and development, strategic change, and internal and external communications. She set aside time to provide more specifics to how and why Gap Inc. places so much emphasis on corporate social responsibility

    Measuring Shear Viscosity Using Transverse Momentum Correlations in Relativistic Nuclear Collisions

    Get PDF
    Elliptic flow measurements at RHIC suggest that quark gluon plasma flows with very little viscosity compared to weak coupling expectations, challenging theorists to explain why this fluid is so nearly ``perfect''. It is therefore vital to find quantitative experimental information on the viscosity of the plasma. We propose that measurements of transverse momentum fluctuations can be used to determine the shear viscosity. We use current data to estimate the viscosity-to-entropy ratio in the range from 0.08 to 0.3, and discuss how future measurements can reduce this uncertainty.Comment: 4 pages, 2 figure

    Association of five Austrodanthonia species (family Poaceae) with large and small scale environmental features in central western New South Wales

    Twenty-eight natural populations of Wallaby Grasses, Austrodanthonia species, in central western New South Wales were sampled and species presence related to a suite of environmental characteristics. An average of 12 plants were selectively sampled from each population; most populations consisted of at least four out of five species, Austrodanthonia bipartita, A. caespitosa, A. eriantha, A. fulva and A. setacea. Numerous ecological factors allowed the widespread co-occurrence of these closely-related species. Large-scale rainfall and climatic factors were correlated with species-presence but no universal small-scale site environmental variables were important for all species. The most widespread species was Austrodanthonia caespitosa and environmental variations at a local site scale, depending on exposure to solar radiation, may at least partially overcome regional rainfall and climate influences

    Social problem-solving skills and mental health: a comparison of undergraduate cohorts

    Problem Solving Skills is clearly indicated as a graduate attribute at the University of Southern Queensland (USQ) and many other Australian Universities. This study was cross-sectional in design and aimed to compare perceived social problem solving skills and mental health variables between undergraduate year levels. Previous research has shown that first year university students are more likely to indicate signs of depression than students‘ in latter years. Research has also found that groups with higher education have indicated more positive problem solving appraisal. Finally, there is considerable research that has linked poorer problem solving appraisal with higher levels of depression and anxiety. An online test battery was administered to 464 undergraduate students from the USQ. The Problem Solving Inventory, Form B (PSI-B; Heppner, 1988) measured perceived problem-solving ability, and is comprised of three subscales; Problem Solving Confidence, Approach Avoidance and Personal Control.The other measure was the shortened version of the Depression Anxiety Stress Scale (DASS-21;Lovibond & Lovibond, 1995) and measured mental health variables (Depression, Anxiety and Stress). Participants were divided into year level (i.e. first, second or third year), and a one way Analysis of Variance (ANOVA) indicated no significant difference between the groups on any of the problem solving or mental health variables. Given that the USQ has a large mature age student population, students were re-analysed with one-way ANOVA according to age (under 21, 21-29, 30-39 and 40 and over years). Significant differences were found where the two older groups had a more positive problem appraisal than the two younger groups. The two older groups also indicated less depression and anxiety symptoms than the two younger groups. It is suggested that problem solving therapy programs specifically targeting younger students may be worth considerin
