Regimes de empreitada na administração pública : uma análise da matriz de risco e das responsabilidades imputadas à contratada

Trabalho de Conclusão de Curso (graduação) — Universidade de Brasília, Faculdade de Direito, 2021.O presente estudo parte da diferenciação entre os principais tipos de regime de empreitada utilizados pela Administração Pública, quais sejam, o regime de empreitada por preço global, integral e unitário, com o intuito de analisar qual deve ser a matriz de risco comportada pela contratada nos contratos administrativos, sob o alicerce do princípio da juridicidade como forma de relativizar o princípio constitucional da supremacia do interesse público sobre o privado. Em seguida, faz-se uma análise, com base na alocação de risco de cada regime, sobre as responsabilidades assumidas por cada contratante a depender do regime de empreitada escolhido pela Administração Pública para guiar a execução do contrato e atingir os objetivos nele estipulados, de modo a evidenciar, mais uma vez, que regimes distintos comportarão matrizes de risco diversas e, consequentemente, suas responsabilidades serão alteradas de modo a onerar uma das partes, excluindo-se, por exemplo, a análise simplista realizada usualmente com base na Teoria das Áleas. O entendimento de como funciona a matriz de risco e a atribuição de responsabilidades às partes é essencial para que o pacto contratual seja mantido durante o decorrer da execução do contrato. Tal feito encontra-se diretamente ligado à manutenção do equilíbrio econômicofinanceiro do contrato, instituto caracterizado como ferramenta essencial para efetivação do objetivo estipulado contratualmente. A abordagem baseia-se na jurisprudência, na doutrina, nacional e estrangeira, e na legislação pertinente ao tema.The study initially intends to differentiate between the main types of contracting regime used by the Public Administration, being them, the contracting regime by global, integral and unit price, with the purpose of analyzing, based on this distinction, what is the risk allocation that will be behaved by the private enterprise in the administrative contracts, from the perspective of the principle of legality as a way of relativizing the constitutional principle of the supremacy of the public interest over the private. Next, the analysis will be performed based on the risk allocation of each regime, of the responsibilities assumed by each contractor depending on the contracting regime chosen by the Public Administration to guide the execution of the contract and achieve the objectives stipulated in it, in order to evidence, once again, that different regimes will contain a different risk allocation and, consequently, their responsibilities will be altered so as to burden one of the parties, excluding, for example, the simplistic analysis carried out in the past based on the Aleas Theory. The understanding of how the risk allocation and the attribution of responsibilities works to the contracting parties is essential for the contractual agreement to be maintained during the course of the execution of the contract, this is directly linked to the support of the economic-financial balance of the contract, an institute considered as an essential tool for the realization of the contractually stipulated objective. The methodology used in this academic work intends to be based on jurisprudence, doctrine, national and foreign, as well as the relevant legislation

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Functional impairment of systemic scleroderma patients with digital ulcerations: results from the DUO Registry

Objective. Digital ulcers (DUs) are frequent manifestations of systemic scleroderma (SSc). This study assessed functional limitations due to DUs among patients enrolled in the Digital Ulcer Outcome (DUO) Registry, an international, multicentre, observational registry of SSc patients with DU disease. Methods. Patients completed at enrolment a DU-specific functional assessment questionnaire with a 1-month recall period, measuring impairment in work and daily activities, and hours of help needed from others. Physician-reported clinical parameters were used to describe the population. For patients who completed at least part of the questionnaire, descriptive analyses were performed for overall results, and stratified by number of DUs at enrolment. Results. This study included 2327 patients who completed at least part of the questionnaire. For patients with 0, 1-2, and DUs at enrolment, mean overall work impairment during the prior month among employed/self-employed patients was 28\%, 42\%, and 48\%, respectively. Across all included patients, ability to perform daily activities was impaired on average by 35\%, 54\%, and 63\%, respectively. Patients required a mean of 2.0, 8.7, and 8.8 hours of paid help and 17.0, 35.9, and 63.7 hours of unpaid help, respectively, due to DUs in the prior month. Patients with DUs had more complications and medication use than patients with no DUs. Conclusion. With increasing number of DUs, SSc patients reported more impairment in work and daily activities and required more support from others
