ATLAS Jet Energy Scale

Jets originating from the fragmentation of quarks and gluons are the most common, and complicated, final state objects produced at hadron colliders. A precise knowledge of their energy calibration is therefore of great importance at experiments at the Large Hadron Collider at CERN, while is very difficult to ascertain. We present in-situ techniques and results for the jet energy scale at ATLAS using recent collision data. ATLAS has demonstrated an understanding of the necessary jet energy corrections to within \approx 4% in the central region of the calorimeter.Comment: Proceedings from XXXI Physics in Collisio

Motives of Socially Responsible Business Conduct

The social and ecological challenges that governments face have raised their interest in socially responsible business conduct (SRBC). In this article we analyze the motives of executives to perform SRBC. We distinguish three types of motives: financial, ethical and altruistic motives. We test the hypotheses on a sample of 473 executives. The estimation results show that SRBC is driven by a combination of intrinsic and extrinsic motives, but that the intrinsic motives are stronger than the extrinsic motive.intrinsic motivation;extrinsic motivation;corporate social responsibility;socially responsible business conduct

Anecic earthworms and associated ecosystem services in a ley-arable crop

Een vruchtwisseling van gras en maïs zou duurzaam kunnen zijn in termen van nutriëntengebruik, maar het effect op regenwormen is nog onvoldoende bekend. Regenwormen zijn verzameld in permanent akkerland, permanent grasland en grond waarop een vruchtwisseling was toegepast. De hoeveelheid regenwormen was het hoogst in permanent grasland. Na gebruik als akkerland heeft de populatie heeft minstens drie jaar nodig om te herstellen. De populatie anenic wormen waren echter na deze periode nog niet hersteld

Validation of the Depression List (DL) and the Geriatric Depression Scale (GDS-30) in Nursing Home residents in somatic units and dementia special-care units

Een validatie studie teneinde inzicht te geven in 1) de inhoudsvaliditeit, de concurrente validiteit en de interne consistentie van de Geriatric Depression Scale (GDS-30) en de Depressielijst (DL) voor het meten van depressie bij verpleeghuisbewoners en 2) de invloed van cognitief functioneren op het aantal missing items op de DL en de GDS-30. Een cross-sectionele studie met data afkomstig uit de effectstudie ‘Act in Case of Depression’. De steekproefomvang bestond uit verpleeghuisbewoners (N=432) van PG en somatische afdelingen. Meetinstrumenten: DL, GDS-30 en de Mini Mental State Examination (MMSE) voor cognitief functioneren. Experts beoordeelden de DL en de GDS-30 als geschikt voor afname bij verpleeghuisbewoners zonder cognitieve problemen. Echter ongeschikt voor afname bij verpleeghuisbewoners met ernstige cognitieve problemen. Experts vonden de items relevant voor de somatische cliënten, echter was er minder consensus over de itemrelevantie voor PG cliënten. De DL en de GDS-30 vertoonden een sterke interne consistentie en een sterke onderlinge correlatie. Er was geen associatie tussen de stemmingssymptomen van de DL en de GDS-30 en motivatie symptomen van de DL aan de ene kant en de MMSE aan de andere kant. De motivatiesymptomen gemeten met de GDS-30 vertoonden een middelmatige associatie met cognitief functioneren. Cliënten van PG afdelingen hadden meer missing items op de DL en op de GDS-30 dan cliënten van somatische afdelingen. Cognitief functioneren vertoonde een zwakke associatie met het aantal missing items op de DL en de GDS-30

Dualities between Poisson brackets and antibrackets

Recently it has been shown that antibrackets may be expressed in terms of Poisson brackets and vice versa for commuting functions in the original bracket. Here we also introduce generalized brackets involving higher antibrackets or higher Poisson brackets where the latter are of a new type. We give generating functions for these brackets for functions in arbitrary involutions in the original bracket. We also give master equations for generalized Maurer-Cartan equations. The presentation is completely symmetric with respect to Poisson brackets and antibrackets.Comment: 24 pages,Latexfile,corrected (2.7-8) and removed text between (2.9) and (2.10

Scaling up antiretroviral therapy in Malawi-implications for managing other chronic diseases in resource-limited countries.

The national scale-up of antiretroviral therapy (ART) in Malawi is based on the public health approach, with principles and practices borrowed from the successful DOTS (directly observed treatment, short course) tuberculosis control framework. The key principles include political commitment, free care, and standardized systems for case finding, treatment, recording and reporting, and drug procurement. Scale-up of ART started in June 2004, and by December 2008, 223,437 patients were registered for treatment within a health system that is severely underresourced. The Malawi model for delivering lifelong ART can be adapted and used for managing patients with chronic noncommunicable diseases, the burden of which is already high and continues to grow in low-income and middle-income countries. This article discusses how the principles behind the successful Malawi model of ART delivery can be applied to the management of other chronic diseases in resource-limited settings and how this paradigm can be used for health systems strengthening

Do Killing-Yano tensors form a Lie Algebra?

Killing-Yano tensors are natural generalizations of Killing vectors. We investigate whether Killing-Yano tensors form a graded Lie algebra with respect to the Schouten-Nijenhuis bracket. We find that this proposition does not hold in general, but that it does hold for constant curvature spacetimes. We also show that Minkowski and (anti)-deSitter spacetimes have the maximal number of Killing-Yano tensors of each rank and that the algebras of these tensors under the SN bracket are relatively simple extensions of the Poincare and (A)dS symmetry algebras.Comment: 17 page
