    This article aims to discuss female entrepreneurship from a critical perspective, supported by feminist theories based on the relationship between work and social practices. The objective is to understand how female entrepreneurial action can lead to female emancipation. The complexity of the study relies on the chosen research object, which is the entrepreneurial initiatives of woman that work with craft activities. Through a case study, we explore the causes and consequences of the actions of the entrepreneurs organized in the Lace-Makers Association of Morros da Mariana, that produces bilro lace in the city of Ilha Grande, Piau√≠, through the standpoint of power relations and gender. The research finding points out the link between lace-maker¬īs artisanal activities and the reinforcement of traditional gender roles. As a conclusion, we acknowledged that even if production and the sales of lace may be a source of incomes for the group of woman drown together in the Association, the entrepreneurial activity based on craft is not an emancipator act that can subvert the unequal power distribution between man and woman in society. Following this conclusion, we recommend that further studies should take as research object the female entrepreneurial activity based on traditional craftwork.O artigo busca problematizar o empreendedorismo feminino a partir de uma perspectiva cr√≠tica, subsidiada por teorias feministas baseadas na rela√ß√£o entre trabalho e pr√°ticas sociais. O objetivo √© compreender como a a√ß√£o empreendedora pode contribuir para a emancipa√ß√£o feminina. A complexidade do estudo reside no objeto de pesquisa escolhido, qual seja as iniciativas empreendedoras de mulheres dedicadas a atividades artesanais. Por meio de um estudo de caso, exploram-se as causas e consequ√™ncias da a√ß√£o das empreendedoras reunidas na Associa√ß√£o de Rendeiras dos Morros da Mariana, com sua produ√ß√£o de rendas de bilro no munic√≠pio de Ilha Grande, Piau√≠, a partir do vi√©s das rela√ß√Ķes de poder de g√™nero. Os achados do estudo apontam para a vincula√ß√£o entre o desempenho da atividade artesanal das rendeiras e o refor√ßo dos papeis de g√™nero tradicionais. Como conclus√£o, tem-se que mesmo que a produ√ß√£o e comercializa√ß√£o da renda sejam fontes geradoras de recursos para as mulheres da Associa√ß√£o, a atividade empreendedora baseada no artesanato n√£o √© uma a√ß√£o emancipat√≥ria, capaz de subverter a desigual distribui√ß√£o de poder de g√™nero na sociedade em quest√£o. Recomenda-se, a partir dessa conclus√£o, a realiza√ß√£o de outros estudos que tomem como objeto a atividade empreendedora feminina baseada em atividades artesanais tradicionais

    Particle-flow reconstruction and global event description with the CMS detector

    The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic calorimeter, a hermetic hadron calorimeter, a strong magnetic field, and an excellent muon spectrometer. A fully-fledged PF reconstruction algorithm tuned to the CMS detector was therefore developed and has been consistently used in physics analyses for the first time at a hadron collider. For each collision, the comprehensive list of final-state particles identified and reconstructed by the algorithm provides a global event description that leads to unprecedented CMS performance for jet and hadronic tau decay reconstruction, missing transverse momentum determination, and electron and muon identification. This approach also allows particles from pileup interactions to be identified and enables efficient pileup mitigation methods. The data collected by CMS at a centre-of-mass energy of 8 TeV show excellent agreement with the simulation and confirm the superior PF performance at least up to an average of 20 pileup interactions

    Differential cross section measurements for the production of a W boson in association with jets in proton‚Äďproton collisions at ‚ąös = 7 TeV

    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript ‚ąí1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
