A redefinição da gestão escolar a partir da concessão de bonificações docentes

Since the 1990s, evaluation instruments applied by areas outside the school have multiplied in the country under the argument of measuring their quality. Establishing comparisons and rankings, such tools began to be used to reward or punish teachers and schools, whose pedagogical work was linked to success or failure in the tests applied. The aim of this study, in this sense, is to analyze the changes made in the career plan of the teaching profession of a municipal school system to insert the results of a student evaluation as a teaching bonus tool. Based on this, using a documental analysis, we reflect on how school management detaches itself from singular and social objectives in order to adapt to defined macro demands and become an instrument for the reproduction of economistic interests. Authors such as Dale (2010), Thenig (2006), Esquinsani and Dametto (2018) and Freitas (2012) are used as references, which are discussed in relation to the legal artifacts selected through hermeneutics-dialectic. With the analysis, it is identified that, in the case in question, the public power's desire to solve the problem of the quality of education resulted in an evaluation process that holds teachers accountable, directing school management to encourage the achievement of individual professional reward, contrary to democratic precepts.Desde la década de 1990, los instrumentos de evaluación aplicados por áreas externas a la escuela se han multiplicado en el país bajo el argumento de medir su calidad.

El objetivo de este estudio, en este sentido, es analizar los cambios realizados en el plan de carrera de la profesión docente de un sistema escolar municipal para insertar los resultados de una evaluación de estudiantes como herramienta de bonificación docente. A partir de ello, mediante un análisis documental, reflexionamos sobre cómo la gestión escolar se desliga de objetivos singulares y sociales para adaptarse a macrodemandas definidas y convertirse en un instrumento de reproducción de intereses economicistas. Se utilizan como referentes autores como Dale (2010), Thenig (2006), Esquinsani y Dametto (2018) y Freitas (2012), los cuales se discuten en relación a los artefactos jurídicos seleccionados a través de la hermenéutica-dialéctica. Con el análisis, se identifica que, en el caso en cuestión, la voluntad del poder público de resolver el problema de la calidad de la educación resultó en un proceso de evaluación que responsabiliza a los docentes, orientando la gestión escolar para incentivar el logro de recompensas profesionales individuales, contrario a los preceptos democráticos.Desde a década de 1990, multiplicaram-se no país instrumentos avaliativos aplicados por âmbitos externos à escola sob o argumento de mensurar sua qualidade.

A partir disso, fazendo uso de uma análise documental, reflete-se sobre como a gestão da escola desvincula-se de objetivos singulares e sociais para se adaptar a demandas macrodefinidas e se tornar instrumento de reprodução de interesses economicistas. Utilizam-se como referenciais autores como Dale (2010), Thoenig (2006), Esquinsani e Dametto (2018) e Freitas (2012), que são discutidos em relação aos artefatos legais selecionados por meio da hermenêutica-dialética. Com a análise, identifica-se que, no caso em questão, o anseio do poder público em solucionar a problemática da qualidade da educação resultou em um processo avaliativo que responsabiliza os docentes, direcionando a gestão escolar para o estímulo à obtenção de recompensas profissionais individuais, contrariando preceitos democráticos

A UTILIDADE DO INÚTIL DA CIBERDEMOCRACIA PARA A EDUCAÇÃO E PARA A SOCIEDADE

The article consists of presenting an understanding of the useful and useless reflexes of cyberdemocracy through the relations forwarded by the media. Its problematizing demand is the following question: What is the use of the useless and the uselessness of the useful of cybernetically interconnected media in the face of the social, political and educational challenges of the global world? To this end, analyzes by Bauman and Mauro (2016), Lévy (2002), Santaella (2003, 2016), among other authors, are presented, regarding the consequences of media connections mediated by the internet. The research is guided by the qualitative approach and is guided by the literature review. It leads to an understanding of the fragility of cyberdemocracy in broadening and deepening democratic relations in the social, educational and political contexts, but which, however, reliably empowers the performance of expansion and market manipulation interconnected globally.O artigo consiste em apresentar a compreensão quanto aos reflexos do útil e do inútil da ciberdemocracia mediante as relações encaminhadas pelos meios midiáticos. Tem como demanda problematizadora a seguinte questão: Qual é a utilidade do inútil e a inutilidade do útil dos meios ciberneticamente interconectados diante dos desafios sociais, políticos e educacionais do mundo global? Para tanto, são apresentadas análises de Bauman e Mauro (2016), Lévy (2002), Santaella (2003, 2016), entre outros autores, quanto as consequências das conexões midiáticas intermediadas pela internet. A pesquisa encaminha-se pela abordagem qualitativa e orienta-se pela revisão bibliografia. Leva a compreender a fragilidade da ciberdemocracia em alargar e aprofundar as relações democráticas dos contextos social, educacional e político, mas que, no entanto, fidedignamente, empodera o desempenho da ampliação e da manipulação mercadológica interligado globalmente

Padrões sazonais e ontogenéticos da dieta do baiacu de água doce Colomesus asellus (Müller & Troschel, 1849) no alto-médio rio Tocantins

Descrevemos os hábitos alimentares de Colomesus asellus capturados nas margens do rio Tocantins, Brasil Central. Duas expedições de coleta foram realizadas em agosto (estação seca) e em outubro (estação chuvosa) de 2013, a jusante da Usina Hidrelétrica de Lajeado, Estado do Tocantins. A dieta de C. asellus foi caracterizada e comparada entre juvenis e adultos e entre indivíduos capturados na estação seca e na estação chuvosa. Os indivíduos apresentaram marcada segregação temporal, com predominância de adultos nas margens do rio durante a estação seca e predominância de juvenis na estação chuvosa. A dieta desta espécie foi baseada em diversas presas bentônicas, principalmente ninfas de Ephemeroptera (Insecta). Contrariamente às nossas expectativas, a composição da dieta de C. asellus não foi influenciada por mudanças sazonais ou fatores ontogenéticos, mas o tamanho dos indivíduos determinou o número de presas consumidas. Assim, a espécie pode ser classificada como insetívora, sem variação em sua ecologia trófica relacionada à sazonalidade do ambiente ou ao seu tamanho.We described the feeding habits of Colomesus asellus from riverbanks of the upper-middle Tocantins River, Central Brazil. Two sampling expeditions were carried out in August (dry season) and in October (rainy season) of 2013, downstream from the Lajeado Hydroelectric Power Plant, Tocantins state. The diet of C. asellus was characterized and compared between juveniles and adults and between individuals captured in the dry season and in the rainy season. Individuals exhibited marked temporal segregation, with a predominance of adults on the riverbanks during the dry season and the predominance of juveniles in the rainy season. The diet of this species was based on diverse benthic prey, mostly Ephemeroptera nymphs (Insecta). Contrary to our expectations, the diet composition of C. asellus was not influenced by seasonal changes or ontogenetic factors, but the size of individuals determined the number of prey consumed. Thus, C. asellus can be classified in its trophic ecology as an insectivore without relation with fish size and seasonality.Maringá, P

LHCb upgrade software and computing : technical design report

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

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

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 → μ+μ−)/B(Bs → μ+μ−). 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

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

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. 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$^{-1}$. 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

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, 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
