Cultural Diversity, Discrimination and Economic Outcomes: an experimental analysis

Economists have paid increasing attention to the role of cultural diversity in explaining the variability of economic outcomes across societies. We develop an experimental framework that complements existing research in this area. We implement the framework with two cultures that coexist in an industrialized society: the Hispanic and Navajo cultures in the southwestern United States. We vary the ethnic mix of our experimental sessions in order to infer the effect of intercultural interactions on economic behavior and outcomes. We control for demographic differences in our subject pools and elicit beliefs directly in order to differentiate between statistical discrimination and preference-based discrimination. We present clear evidence that Hispanic and Navajo subjects behave differently and that their behavior is affected by the ethnic composition of the experimental session. Our experimental framework has the potential to shed much needed light on economic behavior and outcomes in societies of mixed ethnicity, race and religion.culture, diversity, discrimination, bargaining, economic experiments

Development of N/P AlGaAs free-standing top solar cells for tandem applications

The combination of a free standing AlGaAs top solar cell and an existing bottom solar cell is the highest performance, lowest risk approach to implementing the tandem cell concept. The solar cell consists of an AlGaAs substrate layer, an AlGaAs base layer, an AlGaAs emitter, and an ultra-thin AlGaAs window layer. The window layer is compositionally graded which minimizes reflection at the window layer/emitter interface and creates a built-in electric field to improve quantum response in the blue region of the spectrum. Liquid phase epitaxy (LPE) is the only viable method to produce this free standing top solar cell. Small (0.125 sq cm), transparent p/n AlGaAs top solar cells were demonstrated with optimum bandgap for combination with a silicon bottom solar cell. The efficiency of an AlGaAs/Si stack using the free standing AlGaAs device upon an existing silicon bottom solar cell is 24 pct. (1X, Air Mass Zero (AM0). The n/p AlGaAs top solar cell is being developed in order to facilitate the wiring configuration. The two terminal tandem stack will retain fit, form, and function of existing silicon solar cells. Progress in the development of large area (8 and 16 sq cm), free standing AlGaAs top solar cells is discussed

Hadron Spectroscopy with COMPASS at CERN

The aim of the COMPASS hadron programme is to study the light-quark hadron spectrum, and in particular, to search for evidence of hybrids and glueballs. COMPASS is a fixed-target experiment at the CERN SPS and features a two-stage spectrometer with high momentum resolution, large acceptance, particle identification and calorimetry. A short pilot run in 2004 resulted in the observation of a spin-exotic state with $J^{PC} = 1^{-+}$ consistent with the debated $\pi1(1600)$. In addition, Coulomb production at low momentum transfer data provide a test of Chiral Perturbation Theory. During 2008 and 2009, a world leading data set was collected with hadron beam which is currently being analysed. The large statistics allows for a thorough decomposition of the data into partial waves. The COMPASS hadron data span over a broad range of channels and shed light on several different aspects of QCD.Comment: 4 pages, 5 figure

Toward a descriptive model of galactic cosmic rays in the heliosphere

Researchers review the elements that enter into phenomenological models of the composition, energy spectra, and the spatial and temporal variations of galactic cosmic rays, including the so-called anomalous cosmic ray component. Starting from an existing model, designed to describe the behavior of cosmic rays in the near-Earth environment, researchers suggest possible updates and improvements to this model, and then propose a quantitative approach for extending such a model into other regions of the heliosphere

"A place where I can be me": a role for social and leisure provision to support young people with language impairment

The long-term well-being of children with language impairment is an area of increasing interest to families, educators and employers as language impairment is often life-long. Furthermore, language impairment and psychiatric difficulty are known to overlap in both populations originally diagnosed as having language impairment and those receiving mental health services. However, there are currently little data available about the wider quality of life for people with language impairment, especially from the perspective of the young people themselves. There is a dearth of information about community-based activities provided for the support and leisure of this population. The Afasic Youth Project meets once a week and is one of only a handful of such groups across the United Kingdom
