    Essa pesquisa tem o objetivo de identificar barreiras relacionadas à prática de atividade física por policiais militares em uma Unidade de Polícia Pacificadora (UPP). Foi utilizado um questionário para analisar as barreiras para a prática de atividade física no lazer. A amostra foi composta por 41 policiais militares com idade média de 33,5 ± 3,1 anos, peso médio de 86,7 ± 9,7 quilos e estatura de 1,77 ± 0,05 metros. O Índice de Massa Corporal médio foi de 27,67 ± 3,0. Na amostra, 56,1% praticam atividade física no lazer e 43,9% não praticam atividade física no lazer, 85,4% estão classificados como excesso de peso e 14,6% classificados como peso normal. As barreiras foram significativamente associadas à prática de atividade física, sendo as barreiras mais frequentes excesso de trabalho, compromissos familiares e a falta de energia. O estado nutricional não apresentou associação significativa com as barreiras. Conclui-se que a prática de atividade física entre Policiais Militares é restrita por conta das barreiras que dificultam a prática

    Assessment of math abilities before school entry: a tool development

    The years preceding school entry are pivotal for children to develop fundamental skills that bolster their learning in literacy and math in the following years. Skills like counting and subitizing stand as key predictors of future math abilities. Hence, the availability of universal screening tools is vital to promptly identify children who are lacking in these skills, allowing for tailored classroom practices to meet their needs. This study aimed to develop a mathematical screening tool and assess its psychometric properties. The tool encompasses both group and individual tasks, with the latter evaluating counting, cardinality, subitizing, quantity discrimination, addition, and subtraction. The tool was administered twice to 257 children, aged 5 to 6, in their final year of kindergarten in Portugal, at both the start and end of the school year. The findings reveal that the tasks generally present a low level of difficulty, especially by the end of kindergarten. Factor analysis demonstrated an adequate structure, and all dimensions showed high internal consistency (>.80). There was a medium-to-high intercorrelation among the various tasks. Correlations between task scores at the beginning and end of the school year were high. Furthermore, scores across all tasks correlated with math achievement in the first grade of primary education. These outcomes suggest that the tool is both valid and reliable, making it a useful resource for assessing and intervening in math skills during the critical years before school entry.info:eu-repo/semantics/publishedVersio

    Resumo: O objetivo com o presente estudo foi identificar o perfil dos atores da sociedade civil que contribuem e também são potenciais doadores de entidades carentes em geral, com destaque na doação de alimentos, na Cidade de Guarabira, PB. Para tanto, foi realizada uma pesquisa de caráter exploratório-descritiva, com abordagem quantitativa. A partir de uma amostra de 384 entrevistados, evidenciou-se que uma parcela da população já realiza doações e existe um percentual considerável de pessoas interessadas em realizá-las também. A pesquisa mostrou que a maioria do público que pratica doações é formado por homens, porém, sobre quem não doa, as mulheres se mostraram como potenciais doadoras. Homens e mulheres jovens, entre 20 e 29 anos, preferem doar aquilo que já possuem e não se mostram abertos a comprar alimentos para doar. Pessoas viúvas compõem um grupo ativo no auxílio às entidades carentes, mas não realizam suas doações em forma de alimentos, seguidas das pessoas divorciadas. Pessoas com a faixa de renda baixa mostraram ser um grupo de potenciais doadores por interesse em doar, já as com faixa de renda maior apresentaram interesse maior em comprar para doar. Percebeu-se que, de modo geral, há interesse dos entrevistados em realizar ações que colaborem com entidades sem fins lucrativos da Cidade de Guarabira, PB, sobretudo em relação à doação de alimentos. Para tanto, faz-se necessário voltar para ações de marketing social junto aos doadores e potenciais doadores, para melhor desenvolver estratégias para evitar a perda e o desperdício de alimentos e otimizar o processo de doação.

Doações.   Donors and Potential Donors to Charities: Who are they?   Abstract: The objective of the present study was to identify the profile of civil society actors who contribute and are also potential donors of poor entities in general, with a focus on food donation, in the City of Guarabira, PB. For that, a descriptive exploratory research was conducted, with a quantitative approach. From a sample of 384 interviewees, it was shown that a portion of the population already makes donations and there is a considerable percentage of people interested in accomplishing them as well. Research has shown that the majority of the donating public is men, but women who donate do not donate, as potential donors. Young men and women between the ages of 20 and 29 prefer to donate what they already have and are not open to buying food to donate. Widowed people make up an active group in aid to the needy entities, but do not make their donations in the form of food, followed by the divorced people. People with the low income bracket have shown to be a group of potential donors for interest in donating, while those with higher income brackets have shown greater interest in buying to donate. It was noticed that, in general, the interviewees are interested in carrying out actions that collaborate with non-profit entities in the City of Guarabira, PB, especially in relation to food donation. To do so, it is necessary to turn to social marketing actions, together with donors and potential donors, to better develop strategies to avoid loss and waste of food and optimize the donation process.

    The pTp_{\rm T}-differential production cross sections of the prompt (B feed-down subtracted) charmed mesons D0^0, D+^+, and D+^{*+} in the rapidity range y<0.5|y|<0.5, and for transverse momentum 1<pT<121< p_{\rm T} <12 GeV/cc, were measured in proton-proton collisions at s=2.76\sqrt{s} = 2.76 TeV with the ALICE detector at the Large Hadron Collider. The analysis exploited the hadronic decays D0^0 \rightarrow Kπ\pi, D+^+ \rightarrow Kππ\pi\pi, D+^{*+} \rightarrow D0π^0\pi, and their charge conjugates, and was performed on a Lint=1.1L_{\rm int} = 1.1 nb1^{-1} event sample collected in 2011 with a minimum-bias trigger. The total charm production cross section at s=2.76\sqrt{s} = 2.76 TeV and at 7 TeV was evaluated by extrapolating to the full phase space the pTp_{\rm T}-differential production cross sections at s=2.76\sqrt{s} = 2.76 TeV and our previous measurements at s=7\sqrt{s} = 7 TeV. The results were compared to existing measurements and to perturbative-QCD calculations. The fraction of cdbar D mesons produced in a vector state was also determined.Comment: 20 pages, 5 captioned figures, 4 tables, authors from page 15, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/307
