The Tsunami’s CSR Effect: MNEs and Philanthropic Responses to the Disaster

This paper contributes to the literature on CSR and International Business by linking firm internationalization to corporate philanthropy. Considering the 2004 Tsunami disaster as a highly relevant case of an international societal issue, we analyze the characteristics of the corporate response to the disaster among Fortune Global 500 firms. We find that home region, degree of internationalization, firm size and profitability most strongly influenced the propensity of firms to donate as well as the value of their donations

Measurement of D*+/- meson production in jets from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

This paper reports a measurement of D*+/- meson production in jets from proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb^-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |eta| < 2.5. D*+/- mesons found in jets are fully reconstructed in the decay chain: D*+ -> D0pi+, D0 -> K-pi+, and its charge conjugate. The production rate is found to be N(D*+/-)/N(jet) = 0.025 +/- 0.001(stat.) +/- 0.004(syst.) for D*+/- mesons that carry a fraction z of the jet momentum in the range 0.3 < z < 1. Monte Carlo predictions fail to describe the data at small values of z, and this is most marked at low jet transverse momentum.Comment: 10 pages plus author list (22 pages total), 5 figures, 1 table, matches published version in Physical Review

A Review of the fossil record of turtles of the clade Baenidae

The fossil record of the turtle clade Baenidae ranges from the Early Cretaceous (Aptian—Albian) to the Eocene. The group is present throughout North America during the Early Cretaceous, but is restricted to the western portions of the continents in the Late Cretaceous and Paleogene. No credible remains of the clade have been reported outside of North America to date. Baenids were warmadapted freshwater aquatic turtles that supported high levels of diversity at times through niche partitioning, particularly by adapting to a broad range of dietary preferences ranging from omnivorous to molluscivorous. Current phylogenies place Baenidae near the split of crown-group Testudines. Within Baenidae three more inclusive, named clades are recognized: Baenodda, Palatobaeninae and Eubaeninae. A taxonomic review of the group concludes that of 49 named taxa, 30 are nomina valida, 12 are nomina invalida and 7 are nomina dubia

Search for supersymmetry in final states with jets, missing transverse momentum and one isolated lepton in sqrt{s} = 7 TeV pp collisions using 1 fb-1 of ATLAS data

We present an update of a search for supersymmetry in final states containing jets, missing transverse momentum, and one isolated electron or muon, using 1.04 fb^-1 of proton-proton collision data at sqrt{s} = 7 TeV recorded by the ATLAS experiment at the LHC in the first half of 2011. The analysis is carried out in four distinct signal regions with either three or four jets and variations on the (missing) transverse momentum cuts, resulting in optimized limits for various supersymmetry models. No excess above the standard model background expectation is observed. Limits are set on the visible cross-section of new physics within the kinematic requirements of the search. The results are interpreted as limits on the parameters of the minimal supergravity framework, limits on cross-sections of simplified models with specific squark and gluino decay modes, and limits on parameters of a model with bilinear R-parity violation.Comment: 18 pages plus author list (30 pages total), 9 figures, 4 tables, final version to appear in Physical Review

Reducing heterotic M-theory to five dimensional supergravity on a manifold with boundary

This paper constructs the reduction of heterotic $M$-theory in eleven dimensions to a supergravity model on a manifold with boundary in five dimensions using a Calabi-Yau three-fold. New results are presented for the boundary terms in the action and for the boundary conditions on the bulk fields. Some general features of dualisation on a manifold with boundary are used to explain the origin of some topological terms in the action. The effect of gaugino condensation on the fermion boundary conditions leads to a `twist' in the chirality of the gravitino which can provide an uplifting mechanism in the vacuum energy to cancel the cosmological constant after moduli stabilisation.Comment: 16 pages, RevTe

Measurement of tau polarization in W->taunu decays with the ATLAS detector in pp collisions at sqrt(s) = 7 TeV

In this paper, a measurement of tau polarization in W->taunu decays is presented. It is measured from the energies of the decay products in hadronic tau decays with a single final state charged particle. The data, corresponding to an integrated luminosity of 24 pb^-1, were collected by the ATLAS experiment at the Large Hadron Collider in 2010. The measured value of the tau polarization is Ptau = -1.06 +/- 0.04 (stat) + 0.05 (syst) - 0.07 (syst), in agreement with the Standard Model prediction, and is consistent with a physically allowed 95% CL interval [-1,-0.91]. Measurements of tau polarization have not previously been made at hadron colliders.Comment: 10 pages plus author list (25 pages total), 4 figures, 4 tables, revised author list, matches published EPJC versio

Analysis of the Radiative Heat Transfer in Chains of Nanoparticles

The transfer of heat through radiation plays a crucial role in the thermalization of nanoscale objects thanks to the involvement of evanescent waves. As nanotechnology becomes a prominent area of research and development, the understanding of this phenomenon is becoming more and more crucial. In this work, we investigate the thermalization of linear chains of SiC nanospheres. To that end, we develop an analytical method that allows us to calculate the radiative heat exchange between the particles through the analysis of the normal modes of the system and their corresponding decay rates. Using this approach we analyze the time evolution of the temperature distribution of different structure

Atividades de Educação Ambiental: como Minimizar e Lidar com o Resíduo

Neste trabalho, apresentamos os resultados obtidos com o projeto Atividades de Educação e Ética ambiental: evitando o desperdício e lidando com o lixo, que teve o apoio da Pró-Reitoria de Cultura e Extensão da USP. Este projeto envolveu atividades voltadas à temática ambiental, tais como produção e gerenciamento de resíduos sólidos (orgânicos e recicláveis) em residências, escolas e espaços públicos, além de atividades acerca do desperdício e minimização de resíduos. Foram escolhidas três escolas na cidade de São Carlos-SP, levando em consideração o interesse das equipes de coordenação e professores quanto às propostas do projeto, faixa etária dos estudantes e tipo de instituição (pública ou privada). As atividades permitiram a reflexão e a troca de experiências dentro de uma realidade distante da ideal no tocante aos hábitos de consumo, desperdício e descarte de resíduos. Além disto, levaram a resultados positivos, já que foi possível educar indivíduos quanto às diferentes concepções do meio ambiente. Comparativamente, os estudantes se mostraram interessados de forma distinta às atividades, o que reflete diferentes realidades escolares e familiares. No entanto, depois de tomar conhecimento das questões ambientais, tornaram-se bastante motivados, solidificando uma relação positiva entre a comunidade escolar e o seu entorno.In this paper, we present the results obtained with the project Activities of Environmental Education and Ethics: avoiding waste and dealing with trash, which was supported by the University of São Paulo’s Dean of Culture Community Relations. This project aimed to promote initiatives focused on environmental issues, such as management of waste produced from households, schools and public places (organic and recyclable wastes), waste minimization, and environmental conservation. Three schools from the city of São Carlos-SP were chosen based on the interest manifested by the coordination teams and teachers in the project proposals, on student ages and on types of institution (public or private). The activities offered a framework for reflection and exchange of experiences in a reality far from ideal regarding consumption habits and waste disposal. Without doubt, these actions are always positive, for they are designed to educate individuals concerning different conceptions of the environmental. Comparatively, the students showed to be differently interested in the proposed activities, which it was most related to different realities at home and schools. However, after facing environmental issues, they become highly motivated, solidifying a positive relationship between school and neighborhood

Readiness of the ATLAS liquid argon calorimeter for LHC collisions

The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells have been connected to the ATLAS readout system in preparation for LHC collisions. This paper gives an overview of the liquid argon calorimeter performance measured in situ with random triggers, calibration data, cosmic muons, and LHC beam splash events. Results on the detector operation, timing performance, electronics noise, and gain stability are presented. High energy deposits from radiative cosmic muons and beam splash events allow to check the intrinsic constant term of the energy resolution. The uniformity of the electromagnetic barrel calorimeter response along eta (averaged over phi) is measured at the percent level using minimum ionizing cosmic muons. Finally, studies of electromagnetic showers from radiative muons have been used to cross-check the Monte Carlo simulation. The performance results obtained using the ATLAS readout, data acquisition, and reconstruction software indicate that the liquid argon calorimeter is well-prepared for collisions at the dawn of the LHC era.ATLAS Collaboration, for complete list of authors see http://dx.doi.org/10.1140/epjc/s10052-010-1354-y</p
