Comparison of different lattice definitions of the topological charge

We present a comparison of different definitions of the topological charge on the lattice, using a small-volume ensemble with 2 flavours of dynamical twisted mass fermions. The investigated definitions are: index of the overlap Dirac operator, spectral projectors, spectral flow of the Hermitian Wilson-Dirac operator and field theoretic with different kinds of smoothing of gauge fields (HYP and APE smearings, gradient flow, cooling). We also show some results on the topological susceptibility.Comment: 7 pages, 2 figures, presented at the 32nd International Symposium on Lattice Field Theory (Lattice 2014), 23-28 June 2014, Columbia University, New York, NY, US

Pharmacist professionals in the prevention of drug abuse: updating roles, and opportunities

The objective of this paper was to prepare and provide resources to pharmacists and other healthcare professionals, enabling them to carry out a critical analysis on drug abuse, acquiring knowledge in several areas that effectively contribute to their personal development in this professional field. Professionals play a crucial role in the reduction and prevention of substances abuse, since they are able to advise patient about illicit drugs, psychotropic medicines and alcohol abuse. There is an urgent need to specialize pharmacists to act in the national public health service and contribute to actions aimed at the surrounding community.Esse artigo tem o intuito de preparar e fornecer subsídios a farmacêuticos e outros profissionais de saúde a realizarem uma análise crítica sobre o abuso de drogas adquirindo conhecimento em diversas áreas que contribuam para o seu próprio desenvolvimento nesse campo de atuação. O profissional é fundamental na redução e prevenção ao abuso de substâncias, pois é capaz de aconselhar pacientes sobre o abuso de drogas ilícitas, medicamentos psicotrópicos e álcool. Há urgência na especialização de farmacêuticos para atuarem na saúde pública nacional contribuindo nas ações dirigidas à comunidade

Do Investors Care About Biodiversity?

This paper introduces a new proprietary measure of a firm's negative impact on biodiversity, the corporate biodiversity footprint, and studies whether it is priced in the cross-section of stock returns. Using an international sample of firms, we find no evidence that the biodiversity footprint explains these returns, on average. However, event-study evidence shows that, following the UN Biodiversity Conference (COP15), which raised awareness of biodiversity issues, however, firms with larger corporate biodiversity footprints lost value. This response is consistent with investors revising their valuation of these firms downward upon the prospect that regulations to preserve biodiversity will become more stringent
