ESTRATÉGIAS DOS ESTUDANTES DE LICENCIATURA EM CIÊNCIAS SOCIAIS EM SEUS DESLOCAMENTOS DIÁRIOS DE E PARA A UFRJ

Neste artigo pretendemos apresentar uma parte da pesquisa realizada com estudantes de licenciatura em ciências sociais no Instituto de Filosofia e Ciências Sociais da UFRJ. Dentre as questões abordadas no artigo a problemática central é: Quais são as estratégias dos estudantes com o deslocamento diários para a universidade? Aspectos relacionados ao local de moradia, incluindo cidade e bairro e não excluindo os meios de transporte, são algumas das questões discutidas e debatidas neste artigo e abrem caminhos para futuras discussões sobre desigualdades educacionais e uma geografia de oportunidades para além de políticas públicas focadas no acesso dos estudantes ao ensino superior público.  O artigo utilizou-se de uma pesquisa qualitativa mesclando entrevista e questionário a fim de realizar um levantamento acerca desses alunos. Os resultados apontam que o prestígio e a possibilidade de estudar na UFRJ faz com que estratégias para driblar os desafios diários relacionados a distância sejam criadas por estes estudantes a fim de realizar a graduaçã

The vocation to teach Sociology: François Dubet’s Sociology and the choice of a degree in Social Sciences Teacher at UERJ and UFRJ

Com o advento da Lei n° 11.684/08, a procura pelo curso de licenciatura em Ciências Sociais no Brasil aumentou. Compreendendo-se que a adesão da disciplina de Sociologia no ensino médio faz parte de um processo histórico de intermitências, a presente pesquisa tem o objetivo de analisar as trajetórias dos egressos de dois cursos de licenciatura em Sociologia da Universidade do Estado do Rio de Janeiro e da Universidade Federal do Rio de Janeiro. Para tanto, foram realizadas dezessete entrevistas com egressos dos referidos cursos. Com base na Sociologia de François Dubet, observamos haver um processo de influência de professores e familiares na trajetória acadêmica desses estudantes. Ademais, como resultado, percebemos que uma parte dos entrevistados cursaram a licenciatura em Ciências Sociais devido à facilidade de acesso ao ensino superior, e, consequentemente, a obtenção do diploma em uma universidade pública. Por fim, enfrenta-se o tema da formação de professores no Brasil apontando para a possibilidade de perceber o quão múltiplo é o processo de construção da escolha pelo curso de licenciatura em Ciências Sociais.With the advent of Law 11.684/08, the demand for undergraduate courses in social sciences in Brazil has increased. Understanding that the adoption of the discipline of Sociology in high school is part of a historical process of intermittence. The present research aims to analyze the trajectories of graduates from two undergraduate courses in Sociology at the University do Estado do Rio de Janeiro and the University Federal do Rio de Janeiro. To this end, 17 interviews were conducted with graduates of these courses, in search of their motivation for choosing the course. Based on François Dubet’s Sociology, we observed that there was a process of influence from teachers and family members in the academic trajectory of these students. Furthermore, as a result, we noticed that part of the interviewees pursued a degree in Social Sciences due to the ease of access to higher education, and, consequently, to obtain a diploma in a public university. Finally, we address the theme of teacher education in Brazil, pointing to the possibility of realizing how multiple is the process of construction of the choice for the degree course in Social Sciences

American bullfrog (Lithobates catesbeianus) diet in Uruguay compared with other invasive populations in Southern South America

Between 2000-2020, more than ten new populations of the invasive American bullfrog (Lithobates catesbeianus) have been reported in the southern cone of South America. We studied the stomach contents of 126 bullfrogs from a population at an early invasion stage in Uruguay (Acegua, Cerro Largo Department). We observed a rich diet, with extensive prey volume range (1 mm3 to more than 7 000 mm(3)); the most frequent items were Hymenoptera (19.6%), Coleoptera (16.4%), Amphipoda (13.3%), Anura (8.9%) and Heteroptera (8.7%). Despite some overlap, differences were observed in volume (chi(2) = 54.6, p \u3c0.001, d.f. = 2) and prey quantity (F = 8.1, p \u3c0.001, d.f. = 79) between males, females, and juveniles. Juveniles showed significantly higher consumption of terrestrial prey by count (82% of their total ingestion) than adults (29% for males and 32% for females) (chi(2) = 28.5, p \u3c0.001, d.f. = 2). Adults, especially females, showed a high frequency of cannibalism (33% of their total ingestion; chi(2) = 20.9, p \u3c0.001, d.f. = 2). Comparing our data with other bullfrog regional studies, we found great plasticity in trophic habits and differences in the incidence of cannibalism (higher incidence in the populations of Acegua, Uruguay, and Buenos Aires, Argentina). These differences could be related to local biodiversity, but also could be affected by the invasion phase. Cannibalism frequency was higher in small bullfrog populations, where it could be favoring the establishment success. This shift in foraging strategies during the invasion process had been insufficiently evaluated in amphibians. Knowing the ecological determinants for the invasion by bullfrogs can be useful to the development of management strategies

Search for MSSM Higgs bosons decaying to μ+μ-in proton-proton collisions at √s=13TeV

A search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM). Proton-proton collision data recorded by the CMS experiment at the CERN Large Hadron Collider at a center-of-mass energy of 13TeVwere used, corresponding to an integrated luminosity of 35.9fb-1. The search is sensitive to neutral Higgs bosons produced via the gluon fusion process or in association with a bbquark pair. No significant deviations from the standard model expectation are observed. Upper limits at 95% confidence level are set in the context of the mmod+hand phenomenological MSSM scenarios on the parameter tanβas a function of the mass of the pseudoscalar Aboson, in the range from 130 to 600GeV. The results are also used to set a model-independent limit on the product of the branching fraction for the decay into a muon pair and the cross section for the production of a scalar neutral boson, either via gluon fusion, or in association with bquarks, in the mass range from 130 to 1000GeV

Study of the B +→ J / ψ Λ ¯ p decay in proton-proton collisions at √s = 8 TeV

A study of the B +→ J / ψ Λ ¯ p decay using proton-proton collision data collected at s = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb−1, is presented. The ratio of branching fractions B(B+→J/ψΛ¯p)/B(B+→J/ψK∗(892)+) is measured to be (1.054 ± 0.057(stat) ± 0.035(syst) ± 0.011(B))%, where the last uncertainty reflects the uncertainties in the world-average branching fractions of Λ ¯ and K*(892) + decays to reconstructed final states. The invariant mass distributions of the J / ψ Λ ¯ , J/ψp, and Λ ¯ p systems produced in the B +→ J / ψ Λ¯ p decay are investigated and found to be inconsistent with the pure phase space hypothesis. The analysis is extended by using a model-independent angular amplitude analysis, which shows that the observed invariant mass distributions are consistent with the contributions from excited kaons decaying to the Λ ¯ p system.
