Another look at anomalous J/Psi suppression in Pb+Pb collisions at P/A = 158 GeV/c

A new data presentation is proposed to consider anomalous $J/\Psi$ suppression in Pb + Pb collisions at $P/A=158$ GeV/c. If the inclusive differential cross section with respect to a centrality variable is available, one can plot the yield of J/Psi events per Pb-Pb collision as a function of an estimated squared impact parameter. Both quantities are raw experimental data and have a clear physical meaning. As compared to the usual J/Psi over Drell-Yan ratio, there is a huge gain in statistical accuracy. This presentation could be applied advantageously to many processes in the field of nucleus-nucleus collisions at various energies.Comment: 6 pages, 5 figures, submitted to The European Physical Journal C; minor revisions for final versio

Food Commercials and Kids: Characterizing Advertising Content of Children's Online Television Programs

Internet marketing has gained attention as a new medium to advertise food products to children. This study examines the prevalence of food marketing during children's television programs that are available on the internet. While food is the largest product category advertised, commercials make up a smaller portion of episode time online compared to previous reports of television advertising.Internet Food Marketing, Childhood Obesity, Content Analysis, Food Consumption/Nutrition/Food Safety, Marketing,

“The uh deconstructed pumpkin pie”: the use of 'uh' and 'um' in Los Angeles restaurant server talk

Recent work on the elements uh and um has focused both on their functional profile and on the sociodemographic patterns of use. They have been shown to be more than just a signal of some trouble in the speech production process; they also perform text structuring functions that are usually ascribed to discourse markers. And their use has been shown to stratify according to gender, age and level of education (e.g. Tottie 2011, 2014). However, such work has not always been sufficiently controlled for context. Differences that were identified for specific speaker groups may ultimately have been caused by different speaker roles or by differences in the formality or privacy of the communicative situation. For this reason, we focus on one single communicative situation, service encounters in selected and socially stratified Los Angeles restaurants. And we focus on one single speaker role, the role of the server. This allows us to test hypotheses about gender differences and socio-economic stratification in a much more controlled environment. In addition, we provide a functional profile of uh and um in this carefully delimited context, and we show that they are not only used in their often-described functions as planners, hesitators or repair managers but also with a highlighting or a face-mitigating function. The highlighting function turns out to be particularly prominent to emphasize food terminology when servers present menu items to their guests

Predesign study for a modern 4-bladed rotor for the NASA rotor systems research aircraft

Trade-off study results and the rationale for the final selection of an existing modern four-bladed rotor system that can be adapted for installation on the Rotor Systems Research Aircraft (RSRA) are reported. The results of the detailed integration studies, parameter change studies, and instrumentation studies and the recommended plan for development and qualification of the rotor system is also given. Its parameter variants, integration on the RSRA, and support of ground and flight test programs are also discussed
