    This research analyzes whether there is a temporal association between investor sentiment and earnings management in Brazil. Several studies have investigated the determinants of earnings management, such as factors inside or external to companies and regulatory requirements, but few have considered personal factors, such as investor sentiment in Brazil. With this investigation, it was apparent from the findings that accruals quality is affected by investor sentiment. For participants in the Brazilian capital market, this research reinforces the need for a more careful analysis of the results reported by companies, since managers, in response to investor sentiment, may manage earnings to inflate accounting profit through accruals and influence the market’s ability to price shares correctly. It is evident that accounting choices are much more than just financial decisions and are subject to investor sentiments. The effect of investor sentiment should be considered among the determinants of future earnings management. A sample of non-financial Brazilian companies that traded shares on the Brasil, Bolsa, BalcĂŁo (B3) exchange from 2010 to 2016 was used. The investor sentiment index was calculated according to the methodology of Baker and Wurgler (2007). For earnings management, the models of Kang and Sivaramakrishnan (1995), Kothari, Leone, and Wasley (2005), and Dechow, Hutton, Kim, and Sloan (2012) were used. The estimates were carried out through regressions for pooled panel data, fixed, and dynamic effects using the system generalized method of moments (GMM) estimator. Discretionary accruals are positively associated with investor sentiment in the Brazilian capital market, in a similar way to markets with greater informational efficiency and notwithstanding the code-law system. Analyzing low and high sentiment periods separately, the findings suggest that managers increase accruals after high sentiment and reduce them after low sentiment.A pesquisa analisa se existe associação temporal entre o sentimento do investidor e o gerenciamento de resultados no Brasil. VĂĄrios estudos investigaram os determinantes do gerenciamento de resultados, fatores externos ou internos das empresas e normativos, mas poucos consideraram fatores pessoais, tal como o sentimento dos investidores no Brasil. Com esta investigação, restou patente, pelos achados, que a qualidade dos accruals Ă© afetada pelo sentimento do investidor. Para os participantes do mercado de capitais brasileiro, esta pesquisa reforça a necessidade da anĂĄlise mais criteriosa dos resultados reportados pelas empresas, uma vez que os gestores, em resposta ao sentimento do investidor, podem gerenciar resultados para inflar o lucro contĂĄbil mediante accruals e influenciar a capacidade de o mercado precificar corretamente as açÔes. Evidencia-se que, muito mais do que decisĂ”es financeiras, as escolhas contĂĄbeis estĂŁo sujeitas aos sentimentos dos investidores. Deve-se considerar o efeito do sentimento dos investidores entre os determinantes de um futuro gerenciamento de resultados. Utilizou-se amostra composta por empresas brasileiras nĂŁo financeiras que negociaram açÔes na Brasil, Bolsa e BalcĂŁo (B3) de 2010 a 2016. O Ă­ndice de sentimento do investidor foi apurado conforme a metodologia de Baker e Wurgler (2007). Para gerenciamento de resultados, utilizaram-se os modelos de Kang e Sivaramakrishnan (1995), Kothari, Leone e Wasley (2005) e Dechow, Hutton, Kim e Sloan (2012). As estimativas foram feitas por meio de regressĂ”es para dados em painel pooled, efeito fixo e dinĂąmico com o GMM system estimator (generalized method of moments). Os accruals discricionĂĄrios estĂŁo positivamente associados com o sentimento do investidor no mercado de capitais brasileiro, semelhante a mercados com maior eficiĂȘncia informacional e inobstante o sistema code-law. Analisando separadamente os perĂ­odos de baixo e alto sentimento, os achados sugerem que os gestores aumentam os accruals apĂłs alto sentimento e os reduzem depois de baixo sentimento

    More prevalent in people with compromised immune systems and chronic illnesses, sepsis is the body's inflammatory response to a serious infection that can affect multiple organs. This condition is a global problem, with millions of cases annually, resulting in high mortality rates, especially in Brazil. The study seeks to describe the epidemiological profile of hospital morbidity due to septicemia in Brazil. This is an ecological, descriptive and retrospective study, using data from the SUS Information and IT Department (DATASUS) on hospital admissions. Individuals hospitalized for septicemia in the country, from 2019 to 2023, were included. The variables analyzed were region, character service, sex and color/race. The majority of hospitalizations were urgent (95.29%), with a higher prevalence in patients aged 80 or over (21.42%). There was an almost equal distribution between the sexes, with a slight male predominance (52.05%). Regarding color/race, the majority of patients were brown (38.15%), followed by white (37.76%). From this analysis, the relevance of patient care to prevent the development of sepsis and address it appropriately stands out.Mais prevalente em pessoas com sistema imunolĂłgico comprometido e doenças crĂŽnicas, a sepse Ă© uma resposta inflamatĂłria do corpo a uma infecção grave, podendo afetar vĂĄrios ĂłrgĂŁos.

    Physics case for an LHCb Upgrade II - Opportunities in flavour physics, and beyond, in the HL-LHC era

    Get PDF
    The LHCb Upgrade II will fully exploit the flavour-physics opportunities of the HL-LHC, and study additional physics topics that take advantage of the forward acceptance of the LHCb spectrometer. The LHCb Upgrade I will begin operation in 2020. Consolidation will occur, and modest enhancements of the Upgrade I detector will be installed, in Long Shutdown 3 of the LHC (2025) and these are discussed here. The main Upgrade II detector will be installed in long shutdown 4 of the LHC (2030) and will build on the strengths of the current LHCb experiment and the Upgrade I. It will operate at a luminosity up to 2×1034 cm−2s−1, ten times that of the Upgrade I detector. New detector components will improve the intrinsic performance of the experiment in certain key areas. An Expression Of Interest proposing Upgrade II was submitted in February 2017. The physics case for the Upgrade II is presented here in more depth. CP-violating phases will be measured with precisions unattainable at any other envisaged facility. The experiment will probe b → sl+l−and b → dl+l− transitions in both muon and electron decays in modes not accessible at Upgrade I. Minimal flavour violation will be tested with a precision measurement of the ratio of B(B0 → ÎŒ+Ό−)/B(Bs → ÎŒ+Ό−). Probing charm CP violation at the 10−5 level may result in its long sought discovery. Major advances in hadron spectroscopy will be possible, which will be powerful probes of low energy QCD. Upgrade II potentially will have the highest sensitivity of all the LHC experiments on the Higgs to charm-quark couplings. Generically, the new physics mass scale probed, for fixed couplings, will almost double compared with the pre-HL-LHC era; this extended reach for flavour physics is similar to that which would be achieved by the HE-LHC proposal for the energy frontier

    LHCb upgrade software and computing : technical design report

    Get PDF
    This document reports the Research and Development activities that are carried out in the software and computing domains in view of the upgrade of the LHCb experiment. The implementation of a full software trigger implies major changes in the core software framework, in the event data model, and in the reconstruction algorithms. The increase of the data volumes for both real and simulated datasets requires a corresponding scaling of the distributed computing infrastructure. An implementation plan in both domains is presented, together with a risk assessment analysis

    Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

    Full text link
    Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a ZZ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 <pT<100< p_{\textrm{T}} < 100 GeV and in the pseudorapidity range 2.5<η<42.5 < \eta < 4. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb−1^{-1}. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

    Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

    Full text link
    The decay B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} is studied in proton-proton collisions at a center-of-mass energy of s=13\sqrt{s}=13 TeV using data corresponding to an integrated luminosity of 5 fb−1\mathrm{fb}^{-1} collected by the LHCb experiment. In the Λc+K−\Lambda_{c}^+ K^{-} system, the Ξc(2930)0\Xi_{c}(2930)^{0} state observed at the BaBar and Belle experiments is resolved into two narrower states, Ξc(2923)0\Xi_{c}(2923)^{0} and Ξc(2939)0\Xi_{c}(2939)^{0}, whose masses and widths are measured to be m(Ξc(2923)0)=2924.5±0.4±1.1 MeV,m(Ξc(2939)0)=2938.5±0.9±2.3 MeV,Γ(Ξc(2923)0)=0004.8±0.9±1.5 MeV,Γ(Ξc(2939)0)=0011.0±1.9±7.5 MeV, m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV}, where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt Λc+K−\Lambda_{c}^{+} K^{-} sample. Evidence of a new Ξc(2880)0\Xi_{c}(2880)^{0} state is found with a local significance of 3.8 σ3.8\,\sigma, whose mass and width are measured to be 2881.8±3.1±8.5 MeV2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV} and 12.4±5.3±5.8 MeV12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}, respectively. In addition, evidence of a new decay mode Ξc(2790)0→Λc+K−\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-} is found with a significance of 3.7 σ3.7\,\sigma. The relative branching fraction of B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} with respect to the B−→D+D−K−B^{-} \to D^{+} D^{-} K^{-} decay is measured to be 2.36±0.11±0.22±0.252.36 \pm 0.11 \pm 0.22 \pm 0.25, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages
