O incumprimento dos contratos probatórios
O presente estudo tem como propósito uma análise acerca do incumprimento dos contratos processuais probatórios. Os contratos de prova não são uma novidade, já que existem, pelo menos desde os novecentos. A análise desses negócios, na perspectiva do inadimplemento, é praticamente inexistente e mesmo com uma sucessão de leis a regular-lhes a constituição e a eficácia, nunca houve um espaço para que descumprimento dos pactos fosse objeto de regulação. Mesmo em não havendo previsão normativa a respeito do descumprimento dos contratos probatórios na esfera processual, poderá haver situações práticas em que esses negócios deixem de ser observados, durante a sua execução, que exigirão uma resposta jurÃdica devidamente clara a respeito. Assim, a partir da classificação e das modalidades de contratos probatórios, analisam-se as diversas possibilidades de inadimplemento que podem suceder durante a execução dos pactos, como a impossibilidade, o inadimplemento absoluto e relativo, o cumprimento defeituoso e a alteração das circunstâncias, bem como as consequências jurÃdicas que daà poderão advir à s partes do negócio. Desse modo, em havendo o inadimplemento dos contratos probatórios, serão analisadas as possibilidades para se apurar as consequências do incumprimento, a partir do direito material e do direito processual, com prevalência à reconstituição natural, mas sem prejuÃzo de indenização por danos, podendo ser fixada uma cláusula penal, além de condenação por litigância de má-fé e aplicação de sanções pecuniárias compulsórias. Destaca-se, ainda, ponto que versa sobre os contratos probatórios em relação à s partes e ao tribunal, quando será colocada em discussão a ideia de que em negócios processuais não se está diante de deveres ou obrigações de prestar. A partir dessa noção, coloca-se em xeque o uso da ação de cumprimento como meio de reação da parte que se vê confrontada com o incumprimento e propõe-se o uso da exceção processual dilatória, com algumas exceções. Na perspectiva do tribunal, que não participa da conclusão dos contratos probatórios, em regra, esses negócios serão analisados como algo similar aos contratos com eficácia de proteção para terceiros, cuja eficácia atinge o órgão decisor, que tem o dever de aplicar os contratos e poderá, inclusive, descumpri-los, quando julgar a causa.The purpose of this thesis is to analyze the nonperformance of proof contracts. Proof contracts are not new, as they have been around since the nineteen hundred centuries. The analysis of these agreements, from the perspective of breaching, has always been practically non-existent and even with a succession of laws regulating their constitution and efficacy, there has never been a room for regulation of nonperformance of these contracts. Even if there is no normative provision regarding nonperformance of proof contracts, there may be practical situations in which these agreements are no longer performed, during their execution, which will require a duly clear legal response in this regard. Thus, based on the classification and modalities of proof contracts, the various possibilities of breaching that may occur during the execution of agreements are analyzed, such as impossibility to perform, substantial nonperformance or failure to perform, defective performance and unexpected circumstances, as well as the legal consequences that may result to the parties. Hence, in the event of nonperformance of the proof contracts, the possibilities to determine the consequences of breaching will be analyzed, based on material law and procedural law, but without prejudice to rights for damages, which may be fixed by a penal clause, in addition to conviction for litigation in bad faith and application of periodic penalty payments. Also noteworthy is the point that deals with proof contracts in relation to the parties and the court, when the idea that procedural contracts do not deal with duties or obligations to perform will be discussed. Based on this notion, the use of performance action is questioned as a means of reaction by the party that is confronted with the breaching, thus the use of the procedural exception is proposed, with some exclusions. From the perspective of the court, which does not participate in the conclusion of proof contracts, these agreements will be analyzed as something similar to contracts with protection for third parties, whose efficacy affects the court, which has the duty to apply the contracts and may even breach them, when adjudicating the case
Organizational identity: a critical analysis of Brazilian academic production from 2004 to 2009
Se ha observado cierto malestar entre académicos al tratar la Identidad Organizacional (IO) como un área establecida de investigación cientÃfica. Dicho malestar posiblemente se relaciona con la existencia simultánea de conceptos diversos sobre el tema, que proceden de diferentes perspectivas filosóficas, epistemológicas y metodológicas, lo que contribuye a la ausencia de claridad conceptual e incertidumbres empÃricas. En este artÃculo se presentan los principales resultados de una investigación en que se buscó identificar los caminos ontológicos, epistemológicos y metodológicos que han sido adoptados en la producción académica brasileña sobre IO. Para ello, se realizó una investigación bibliográfica exploratoria, con la ayuda del método cualitativo. Los resultados señalan similitudes en la crÃtica de las producciones académicas brasileña e internacional. Una de ellas se refiere a la omisión de los criterios utilizados para determinar las caracterÃsticas de centralidad, distinción y continuidad temporal de los elementos elegidos como parte de la identidad de las organizaciones estudiadas. Otra, señala la manera abstracta como los cambios en la IO han sido tratados en los estudios organizacionales. Se apuntan diversas lagunas y se concluye el artÃculo con recomendaciones para que se realicen más investigación sobre el tema de una manera estructurada y consistente, con vistas a contribuir efectivamente al avance del conocimiento y a la construcción de la teorÃa sobre la identidad organizacional.Identificou-se certo desconforto entre acadêmicos em lidar com a Identidade Organizacional (IO) como uma área estabelecida da pesquisa cientÃfica.

The product of the () differential production
cross-section and the branching fraction of the decay () is
measured as a function of the beauty hadron transverse momentum, ,
and rapidity, . The kinematic region of the measurements is and . The measurements use a data sample
corresponding to an integrated luminosity of collected by the
LHCb detector in collisions at centre-of-mass energies in 2011 and in 2012. Based on previous LHCb
results of the fragmentation fraction ratio, , the
branching fraction of the decay is
measured to be \begin{equation*} \mathcal{B}(\Lambda_b^0\rightarrow J/\psi
pK^-)= (3.17\pm0.04\pm0.07\pm0.34^{+0.45}_{-0.28})\times10^{-4},
\end{equation*} where the first uncertainty is statistical, the second is
systematic, the third is due to the uncertainty on the branching fraction of
the decay , and the

Measurements of long-range near-side angular correlations in TeV proton-lead collisions in the forward region
Two-particle angular correlations are studied in proton-lead collisions at a
nucleon-nucleon centre-of-mass energy of TeV, collected
with the LHCb detector at the LHC. The analysis is based on data recorded in
two beam configurations, in which either the direction of the proton or that of
the lead ion is analysed. The correlations are measured in the laboratory
system as a function of relative pseudorapidity, , and relative
azimuthal angle, , for events in different classes of event
activity and for different bins of particle transverse momentum. In
high-activity events a long-range correlation on the near side, , is observed in the pseudorapidity range . This
measurement of long-range correlations on the near side in proton-lead
collisions extends previous observations into the forward region up to
. The correlation increases with growing event activity and is found
to be more pronounced in the direction of the lead beam. However, the
correlation in the direction of the lead and proton beams are found to be
compatible when comparing events with similar absolute activity in the
direction analysed.Comment: All figures and tables, along with any supplementary material and

Evidence for the strangeness-changing weak decay
Using a collision data sample corresponding to an integrated luminosity
of 3.0~fb, collected by the LHCb detector, we present the first search
for the strangeness-changing weak decay . No
hadron decay of this type has been seen before. A signal for this decay,
corresponding to a significance of 3.2 standard deviations, is reported. The
relative rate is measured to be

Search for the rare decays and
A search for the rare decay of a or meson into the final
state is performed, using data collected by the LHCb experiment
in collisions at and TeV, corresponding to an integrated
luminosity of 3 fb. The observed number of signal candidates is
consistent with a background-only hypothesis. Branching fraction values larger
than for the decay mode are
excluded at 90% confidence level. For the decay
mode, branching fraction values larger than are excluded at
90% confidence level, this is the first branching fraction limit for this
decay.Comment: All figures and tables, along with any supplementary material and

How to break bad news: State-of-the-art of letting go
Seven observations point towards the existence of primordial black holes (PBH), constituting the whole or an important fraction of the dark matter in the Universe: the mass and spin of black holes detected by Advanced LIGO/VIRGO, the detection of micro-lensing events of distant quasars and stars in M31, the non-detection of ultra-faint dwarf satellite galaxies with radius below 15 parsecs, evidences for core galactic dark matter profiles, the correlation between X-ray and infrared cosmic backgrounds, and the existence of super-massive black holes very early in the Universe's history. Some of these hints are newly identified and they are all intriguingly compatible with the re-constructed broad PBH mass distribution from LIGO events, peaking on PBH mass [Formula presented] and passing all other constraints on PBH abundances. PBH dark matter also provides a new mechanism to explain the mass-to-light ratios of dwarf galaxies, including the recent detection of a diffuse galaxy not dominated by dark matter. Finally we conjecture that between 0.1% and 1% of the events detected by LIGO will involve a PBH with a mass below the Chandrasekhar mass, which would unambiguously prove the existence of PBH.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Study of ψ(2S) production and cold nuclear matter effects in pPb collisions at √ sNN = 5 TeV
The production of ψ(2S) mesons is studied in dimuon final states using proton-lead (pPb) collision data collected by the LHCb detector. The data sample corresponds to an integrated luminosity of 1.6 nb−1. The nucleon-nucleon centre-of-mass energy of the pPb collisions is (Formula presented.) TeV. The measurement is performed using ψ(2S) mesons with transverse momentum less than 14 GeV/c and rapidity y in the ranges 1.5 < y < 4.0 and −5.0 < y < −2.5 in the nucleon-nucleon centre-of-mass system. The forward-backward production ratio and the nuclear modification factor are determined for ψ(2S) mesons. Using the production cross-section results of ψ(2S) and J/ψ mesons from b-hadron decays, the (Formula presented.) cross-section in pPb collisions at (Formula presented.) TeV is obtained
Measurements of long-range near-side angular correlations in √sNN = 5 TeV proton-lead collisions in the forward region
Two-particle angular correlations are studied in proton-lead collisions at a nucleon–nucleon centre-of-mass energy of √sNN = 5 TeV , collected with the LHCb detector at the LHC. The analysis is based on data recorded in two beam configurations, in which either the direction of the proton or that of the lead ion is analysed. The correlations are measured in the laboratory system as a function of relative pseudorapidity, Δη, and relative azimuthal angle, Δϕ, for events in different classes of event activity and for different bins of particle transverse momentum. In high-activity events a long-range correlation on the near side, Δ ϕ ≈ 0 , is observed in the pseudorapidity range 2.0 < η < 4.9 . This measurement of long-range correlations on the near side in proton-lead collisions extends previous observations into the forward region up to η = 4.9 . The correlation increases with growing event activity and is found to be more pronounced in the direction of the lead beam. However, the correlation in the direction of the lead and proton beams are found to be compatible when comparing events with similar absolute activity in the direction analysed
