How “Point Blindness” Dilutes the Value of Stock Market Reports

The stock index “point” is a focal component of financial news reports. Though many reports draw attention to point changes in major indices, few people realize that the value of a stock index “point” changes frequently. We call this perceptual phenomenon “point blindness.” We examine causes of point blindness and then propose alternate ways of reporting stock market information to counter it. The alternatives are easy to implement and can help citizens draw important inferences about stock values. An experiment shows that alternate modes of presentation have significant effects on public perceptions of the stock market.stock market; stock index; financial reporting; news; real nominal relations

How “Point Blindness” Dilutes the Value of Stock Market Reports

The stock index “point” is a focal component of financial news reports. While much attention is paid to changes in stock index point totals, few people realize that the value of a stock index “point” varies (and has recently declined). We call this perceptual phenomenon “point blindness” and explain its threat to investors. Simple changes in media presentations of stock index information can counter point blindness. These changes are easy to implement and can help audiences make better financial decisions. An experiment on over 2000 participants shows such changes significantly altering their perceptions of the stock market.behavioral economics: personal finance; communication

A Very High-beta Optics to be used for an Absolute Luminosity Determination with Forward Detectors in ATLAS

The Atlas experiment at the LHC pursues a number of different approaches to obtain an estimate of the absolute luminosity [3]. Measuring elastic scattering at very small angles (3 μrad) represents a different and complimentary approach that will improve the precision of the final luminosity estimate. In this paper we show the required very high-β optics and the detector acceptance studies

Quantitative Nanofriction Characterization of Corrugated Surfaces by Atomic Force Microscopy

Atomic Force Microscopy (AFM) is a suitable tool to perform tribological characterization of materials down to the nanometer scale. An important aspect in nanofriction measurements of corrugated samples is the local tilt of the surface, which affects the lateral force maps acquired with the AFM. This is one of the most important problems of state-of-the-art nanotribology, making difficult a reliable and quantitative characterization of real corrugated surfaces. A correction of topographic spurious contributions to lateral force maps is thus needed for corrugated samples. In this paper we present a general approach to the topographic correction of AFM lateral force maps and we apply it in the case of multi-asperity adhesive contact. We describe a complete protocol for the quantitative characterization of the frictional properties of corrugated systems in the presence of surface adhesion using the AFM.Comment: 33 pages, 9 figures, RevTex 4, submitted to Journal of Applied Physic

Comments on low mass dissociation at the LHC in the context of the discrepancy between the ATLAS and TOTEM measurements of σtot\sigma_{tot}

The cross section for low mass dissociation at LHC energies is estimated in a partly data driven approach. The result is compared to the Monte Carlo estimate from the QGSJET-II-03 model used by the TOTEM experiment in the determination of $\sigma_{tot}$ via the luminosity-independent method. Significant differences are found and possible consequences are explored and discussed.Comment: 11 pages, 5 figure

The total cross section for proton-proton interactions at the FCC

The lower and upper limits of the total cross section ($\sigma_{tot}$) at the projected FCC-hh have been estimated. A lower limit has been estimated using dispersion relations in combination with recent LHC data of $\sigma_{tot}$ and the $\rho$-parameter. The upper limit has been estimated using the standard $ln^{2}(s)$ evolution of $\sigma_{tot}$. Some models giving values in between those limits are also discussed

Identifying and Mitigating Caregiver Burnout: The Role of Adult Day Social Workers

This qualitative research study will explore the role of adult day social workers in identifying and mitigating caregiver burnout. To collect data for this study, eight semi-structured interviews with adult day social workers were completed to analyze their experience with caregivers, their role in recognizing burnout and their response to caregivers experiencing burnout. A grounded theory methodology approach will be used to analyze data. This method will use an open-coding process that will lead to selective coding, which will assist in identifying and validating themes and concepts from the participant’s responses to interview questions. The findings from this study indicate the strong role adult day social workers play in identifying burnout among caregivers by providing support that aligns with best practices in the adult day setting. Further research in this area will also assist social workers in the continuation of best practice development and to be effective in providing the needed support of caregivers on a mental, psychological, physical and emotional levels

Measurement of the branching ratio of the decay Ξ0→Σ+μ−νˉμ\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}

From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$ candidates with a background contamination of $30.8 \pm 4.2$ events. From this sample, the BR($\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$) is measured to be $(2.17 \pm 0.32_{\mathrm{stat}}\pm 0.17_{\mathrm{syst}})\times10^{-6}$
