A Importância do Animal de Estimação no Desenvolvimetno Infantil / The Importance of Domestic Pets in Child Development
Authors: Lenares Bruna , Oliveira Janaina Silva
Published: May 2022

Resumo: Especialmente para as crianças, os animais de estimação podem ser maravilhosos facilitadores sociais. As crianças são mais propensas a se aproximar e interagir com outra criança que está brincando com um animal de estimação. Desta forma, o animal de estimação pode ser uma ponte entre uma criança menos sociável e extrovertida e outros potenciais companheiros. O próprio animal de estimação pode ser um objeto social para as crianças devido à natureza de seu relacionamento. Nesse contexto, o objetivo geral desse estudo é verificar os principais benefícios dos animais de estimação no desenvolvimento social, cognitivo e emocional das crianças. Para alcançar o objetivo proposto foi utilizada a pesquisa descritiva de natureza qualitativa e revisão bibliográfica. Os resultados mostram que animais de estimação ou animais domésticos podem ser um elemento importante para o desenvolvimento da criança em todos os seus aspectos: físico e emocional. Palavras-Chave: Animais de estimação. Benefícios. Desenvolvimento Infantil. Abstract: Especially for children, pets can be wonderful social facilitators. Children are more likely to approach and interact with another child who is playing with a pet. In this way, the pet can be a bridge between a less sociable and outgoing child and other potential companions. The pet itself can be a social object for children due to the nature of their relationship. In this context, the general objective of this study is to verify the main benefits of pets in the social, cognitive and emotional development of children. To achieve the proposed objective, descriptive research of a qualitative nature and literature review were used.

Authors: Alencar Layana Dantas , Barbosa Maria de Fátima Nóbrega , Barbosa Erivaldo Moreira
Published: May 2022

O estudo objetivou realizar um comparativo da percepção dos atores sociais, mais diretamente envolvidos com uma escola pública de Campina Grande - PB, acerca das relações entre a PNEA e as práticas de Educação Ambiental. Utilizou-se no estudo o método hermenêutico-sistêmico e o estudo de caso. Observou-se certo descompasso entre as opiniões de cada ator social, bem como elevado nível de distanciamento entre o os fundamentos da Educação Ambiental e as práticas ambientais da instituição. Outros fatores contribuem para a não inserção da Educação Ambiental, dentre eles, a falta de formação complementar dos docentes, o apego ao ensino tradicional e a inércia do Poder Público. Conclui-se que a não aplicabilidade da PNEA ainda é bem considerável, sendo este fator contribuinte para a não inserção da Educação Ambiental na escola.

Published: May 2022

Este artigo propõe uma reflexão crítica sobre a interdisciplinaridade, construção do conhecimento para a produção de saber ambiental complexo que responda aos desafios da problemática ambiental atual. Compreende-se assim, que a interdisciplinaridade deve transcender o somatório de disciplinas para unificar um conhecimento novo gerado no contexto epistemológico de formação e inter-relação do saber. Desta maneira, este texto aborda a interdisciplinaridade como promotora de diálogos de saberes e práticas, baseada em princípios teóricos e metodológicos com a finalidade de reintegrar saberes e reconstituir um conhecimento totalizado na perspectiva científica. Neste sentido, entende-se que os problemas ambientais no campo das relações sociedade-natureza devem adotar um processo complexo de produção de possibilidades.

Financing public schools with private funds: Efficiency–equity trade-off of multi-stakeholder school financing in Punjab, Pakistan
Authors: Sakamoto Jutaro
Published: May 2022

Governments and development partners encourage public school authorities to mobilize private funds from diverse non-state stakeholders as a means to expand funding sources to provide quality education for all. While financing public schools with private funds is expected to promote the efficient use of resources due to increased accountability, it raises concerns about financial equity. Using public school panel data from Learning and Educational Achievements in Punjab Schools (LEAPS) in Pakistan, this study examines how private funds mobilized from different stakeholders are associated with efficiency in educating students at a given achievement level and equity in school finance. School fixed effects analyses show that schools relying on education fees or local community contributions were more likely to reduce inefficient capital expenditure. In girls’ schools, financial dependency on private donors is also associated with a reduction in capital expenditure. However, the results suggest that a heavy reliance on education fees and private donors makes schools less efficient. I find no evidence that mobilizing private-fund revenue widened financial inequity. The findings demonstrate the importance of understanding the differential effects of private-fund revenue to develop effective multi-stakeholder financing systems that improve student achievement in a cost-effective manner and ensure financial equity.

Treatment effect optimisation in dynamic environments
Authors: Berrevoets Jeroen , Verboven Sam , Verbeke Wouter
Published: May 2022

Applying causal methods to fields such as healthcare, marketing, and economics receives increasing interest. In particular, optimising the individual-treatment-effect – often referred to as uplift modelling – has peaked in areas such as precision medicine and targeted advertising. While existing techniques have proven useful in many settings, they suffer vividly in a dynamic environment. To address this issue, we propose a novel optimisation target that is easily incorporated in bandit algorithms. Incorporating this target creates a causal model which we name anuplifted contextual multi-armed bandit. Experiments on real and simulated data show the proposed method to effectively improve upon the state-of-the-art. All our code is made available online athttps://github.com/vub-dl/u-cmab.

Authors: Wang Junping , Ye Xiu , Zhang Shangyou
Published: May 2022

In this paper a time-explicit weak Galerkin finite element method is introduced and analyzed for parabolic equations. The main idea relies on the inclusion of a stabilization term in the temporal direction in addition to the usual static stabilization in the weak Galerkin framework. Both semi-discrete and fully-discrete schemes in time are presented, as well as their stability and error analysis. Numerical results are reported for this new explicit weak Galerkin finite element method.

Published: May 2022

Pregnant women are more susceptible to smog pollution than the general population. This study focused on the association between smog and birth outcomes, considering both pregnant mothers and their offspring. In this retrospective study, conducted in Baoding between 2013 and 2016, we enrolled 842 participants. Birth outcomes were low birth weight (LBW), pregnancy-induced hypertension (PIH), gestational diabetes mellitus (GDM), and premature rupture of membranes (PROM). The overall prevalence of LBW, PIH, GDM, and PROM was 8.2%, 14.8%, 16.5%, and 12.1%, respectively. Compared with lower pollution level, higher pollution level of fine particulate matter (particulate matter with aerodynamics diameter <2.5 μm) (PM2.5), inhalable particle (particulate matter with aerodynamics diameter <10 μm) (PM10), and CO increased the risk of term with LBW. PM2.5, PM10, and NO2 increased the risk of PIH during different trimesters, while PM10 increased the risk of PROM during trimester 3. In conclusion, smog significantly affects the risk of adverse birth outcomes by different exposure time windows.

ICTs, Distributed Discourse and the Labour Movement in Cabo Verde: Why Weak Communications Remain a Crucial Barrier to Trade Union Effectiveness
Authors: McQuinn Mark , Cojocaru Mihaela
Published: May 2022

Based on interviews with trade union officials from different islands and the Inspector General of Labour, this article examines the use of information and communication technologies (ICTs) by labour organisations in Cabo Verde. Distributed discourse is used as a conceptual framework to provide insights into ways in which the ability of trade unionists to engage in debates and formulate initiatives is influenced by the pervasiveness and control of digital technologies. ICTs are premised as complementary tools and not as substitutes for existing face-to-face union communication strategies, a perspective substantiated by all the interviewees. The research reveals that frail communication channels are major problems for unions in Cabo Verde, which significantly impede their ability to defend the rights of members effectively. Despite localised improvements, involving particular organisations, ICTs are not being utilised systematically and equitably across all the Cabo Verdean islands to enhance the effectiveness of the work of unions. Limited financial streams, high levels of informality in the labour force, a dispersed geography, the uneven penetration of digital technologies across islands and economic sectors, and government policies are major barriers to trade union communication. Policy implications are put forward in the light of the main research findings.

Recording Synaptic Transmission from Auditory Mixed Synapses on the Mauthner Cells of Developing Zebrafish
Authors: Echeverry Fabio A. , Ijaz Sundas , Pereda Alberto E.
Published: May 2022

The Mauthner cells are a pair of large reticulospinal neurons that organize sensory-evoked tail flip responses in fishes. An identifiable group of auditory “mixed” (electrical and chemical) synaptic contacts known as “Large Myelinated Club endings” on these cells have provided a valuable model for the study of synaptic transmission in the vertebrate brain. While most of studies were performed in adult fish, we describe here methods that make possible recording synaptic transmission from these contacts in developing zebrafish, a genetically tractable vertebrate species which is uniquely amenable for combining synaptic physiology with live imaging and behavioral analysis.
Extensor mechanism ruptures
Authors: Tandogan Reha N , Terzi Esref , Gomez-Barrena Enrique , Violante Bruno , Kayaalp Asim
Published: May 2022

Native patellar tendon injuries are seen in younger patients compared to quadriceps tendon ruptures.

Up to a third of the patients may have local (antecedent tendinopathy and cortisone injections) or systemic risk factors (obesity, diabetes, hyperparathyroidism, chronic renal failure, fluoroquinolone or statin use) of injury, these are more frequent in bilateral disruptions.

Complete extensor mechanism disruptions should be repaired surgically. Although isolated primary repair has been reported to have good outcomes in younger patients with acute tears and good tendon quality, augmentation of the repair with autograft, allograft or synthetic material should be considered in patients with poor tendon quality, chronic tears or tendon defects.

High rates of return to work/sports have been reported in native patellar and quadriceps tendon tears, with re-rupture rates <5%.

Extensor mechanism disruptions in patients with a total knee arthroplasty are challenging due to older age, systemic co-morbidities and poor local conditions, resulting in inferior outcomes compared to native extensor mechanism injuries. Some form of augmentation with autograft, allograft or synthetics is advisable in all cases. Salvage procedures such as whole extensor mechanism allografts provide acceptable outcomes in multiply operated knees with extensive bone and soft tissue deficits.

Published: May 2022

Insufficient physical activity and obesity are associated with an increased risk of cancer recurrence and death in breast cancer survivors. Sex steroid hormones may mediate these associations. This study tested the hypothesis that exercise and diet, as compared to control, favorably change sex steroid hormones. This analysis of data from a subset of participants in a 2 × 2 factorial trial compares 269 postmenopausal breast cancer survivors who were insufficiently physically active and had overweight or obesity and were randomized to one of four treatment groups for 52 weeks: control, exercise alone, diet alone, or exercise plus diet. Secondary sex steroid hormone endpoints included estradiol, sex hormone-binding globulin (SHBG), and testosterone. Treatment effects were quantified using a mixed model for repeated measures. Compared to control, exercise alone did not significantly change estradiol (−1.9%; 95% CI: −12.6, 8.8), SHBG (2.4%; 95% CI: −9.9, 14.6), or testosterone (1.2%; 95% CI: −12.2, 14.5). Compared to control, diet alone did not significantly change estradiol (−7.8%; 95% CI: −17.6, 1.9), SHBG (8.2%; 95% CI: −4.2, 20.6), or testosterone (−0.8%; 95% CI: −13.6, 12.0). Compared to control, exercise plus diet did not significantly change estradiol (−6.3%; 95% CI: −16.3, 3.6), SHBG (8.8%; 95% CI: −4.0, 21.7), or testosterone (−5.3%; 95% CI: −18.0, 7.4). In postmenopausal breast cancer survivors who were insufficiently physically active and had overweight or obesity, randomization to exercise alone, diet alone, or exercise plus diet did not statistically significantly change sex steroid hormone concentrations at week 52.

A nutrição é um fator limitante na produção e qualidade de sementes de cevada. Nesse sentido, é necessário um adequado suprimento de nitrogênio para a obtenção de produtividade e qualidade fisiológica de sementes. Assim, o objetivo desse trabalho foi avaliar as respostas de duas cultivares de cevada, BRS Brau e BRS Cauê, em diferentes doses de adubação nitrogenada, inferindo sobre a produtividade e a qualidade fisiológica nas diferentes situações. O delineamento experimental utilizado foi de blocos ao acaso, em esquema fatorial 2x4, (duas cultivares X quatro doses de nitrogênio) e os tratamentos consistiram na combinação de duas cultivares (BRS Cauê e BRS Brau) e quatro doses de nitrogênio, totalizando oito tratamentos. O experimento foi conduzido no município de Capão do Leão e a coleta de dados para avaliação da resposta das plantas às doses de nitrogênio quanto ao rendimento e qualidade fisiológica de sementes de cevada, foram analisados no Laboratório de Análise de Sementes do Programa de Pós-Graduação em Ciência e Tecnologia de Sementes. As cultivares BRS Brau e BRS Cauê apresentaram diferentes exigências de nitrogênio para as variáveis altura de planta, rendimento por planta e rendimento total. Em relação à qualidade fisiológica de sementes, a utilização de diferentes doses de nitrogênio não afetou significativamente a germinação e o vigor das sementes. Porém, para as expressões isoenzimáticas, as diferentes doses de adubação nitrogenada influenciaram as plântulas de cevada.

Problems of pronunciation and meaning are very numerous in contemporary linguistic studies which have been studied for their history since the time of the classical Arabs. The problem of pronunciation and meaning in terms of art and technique has been tried to be analyzed.

The increasingly significant influence of Islam in the Archipelago was marked by the establishment of a number of sultanates. It is time for the existence of the sultanate to be interpreted as evidence of political power. The track of Islam in the Archipelago, political power was achieved after great successes in building ECONOMIC POWER, EDUCATION, CULTURAL-INTELLECTUAL NETWORKS. Therefore, the track of Islam in the Archipelago, is not an event that is considered strange. Until the 17th century AD, there were even a number of sultanates on the islands of Java, Kalimantan, Sulawesi, Maluku. The spread of the existence of a number of these sultanates in a relay as evidence of the results of the exemplary performances of a number of sultanates that had existed before. May we all never forget the existence of the Sultanate of Jeumpa (± 776 AD-880 AD), Peureulak (standing ± 840 AD), Samudera Pasai (± 1267 AD), Demak (1468 AD), Aceh Darussalam (1496 AD), Ternate (Maluku). ) rulers converted to Islam in 1460, Cirebon (founded 1479 AD), Banten (1526 AD), Banjar (founded 1520 AD). From the coast of Aceh-Malacca-Sumatra, Islam then spread in various directions east to areas on the north coast of Java such as Surabaya, Gresik, Tuban, then continued eastward to areas of Kalimantan, Sulawesi, Ternate and Tidore in the Maluku islands, Papua, Nusa Tenggara, Bali. The approach used in this paper is a historical approach by utilizing study materials from historical literature. In compiling historical facts, guided by logical arrangement of frameworks in chronological order. The conclusion is that, thanks to the wealth and social forces empowered by Muslim communities in various places in the Archipelago, they can play political roles in political entities as evidenced by the birth of a number of Sultanates. This historical fact, at least strengthens Anthony Reid's theory, that the maritime economy is an indicator of maritime trade that unites trade routes with the formation of port cities as international trade routes.

Desigualdades socioespaciales de la mortalidad por COVID-19 en tres olas de propagación: un análisis intraurbano en Argentina
Authors: Leveau Carlos Marcelo , Bastos Leonardo Soares
Published: May 2022

Nuestro propósito fue investigar las diferencias de las desigualdades socioespaciales de la mortalidad por COVID-19 entre tres olas de propagación del virus en la Ciudad Autónoma de Buenos Aires (CABA), Argentina. Los datos de mortalidad por COVID-19 se obtuvieron de la base de datos de casos de COVID-19, informados por el gobierno de la CABA, desde el 7 de marzo de 2020 hasta el 30 de septiembre de 2021. Se determinaron tres olas: la primera ola, entre los meses de marzo y diciembre de 2020, la segunda ola, entre diciembre y marzo de 2021, y la tercera ola, entre marzo y septiembre de 2021. En cada ola se calcularon regresiones multivariadas para analizar la asociación entre el riesgo de mortalidad por COVID-19, en dos grupos etarios (0-59 años y 60 o más años), y el porcentaje de hogares con necesidades básicas insatisfechas, como indicador del nivel de pobreza de los barrios, y la densidad poblacional. Durante la primera ola y en ambos grupos etarios, los barrios del tercil con mayores porcentajes de hogares con necesidades básicas insatisfechas tuvieron un riesgo mayor de mortalidad por COVID-19, en comparación a los barrios del tercil con menores porcentajes de hogares con necesidades básicas insatisfechas. Estas desigualdades desaparecieron durante la segunda ola en ambos grupos etarios, mientras que en la tercera ola pareció emerger un patrón geográfico similar al de la primera ola. Es posible que mayores niveles de inmunidad en barrios con niveles altos de pobreza pudieran explicar parcialmente la ausencia de desigualdades socioespaciales durante la segunda ola, mientras que la irrupción de las variantes gamma y lambda podría explicar parcialmente el retorno a las desigualdades observadas en la primera ola.
Motivos e mecanismos de internação de crianças e adolescentes em hospital psiquiátrico: o circuito do controle
Authors: Braga Claudia Pellegrini , d’Oliveira Ana Flávia Pires Lucas
Published: May 2022

Os avanços da reforma psiquiátrica incluem a implantação de serviços de saúde mental substitutivos à lógica asilar. Porém, internações em hospitais psiquiátricos, inclusive de crianças e adolescentes, continuam ocorrendo. Esse estudo buscou compreender os motivos de internação em um hospital psiquiátrico a partir da perspectiva da instituição e das crianças e adolescentes internados. Trata-se de pesquisa qualitativa, de abordagem hermenêutico-dialética, tendo sido feita a leitura de documentos institucionais, entrevistas abertas com oito adolescentes e observação participante. Os resultados indicaram que o motivo principal alegado pelo hospital psiquiátrico para internação foi nomeado como “agressividade”, justificada pelo “risco para si e para outros”, enquanto, para as crianças e os adolescentes, os motivos de internação eram múltiplos, incluindo uso de drogas, pequenas brigas e infrações. A análise indicou que os mecanismos para a internação pelo hospital psiquiátrico envolvem, durante a anamnese, uma leitura sobre o outro que o define como desviante de normas sociais e a posterior atribuição de um diagnóstico, avalizando a internação psiquiátrica. Também indicou que a sustentação e continuidade de internações psiquiátricas ocorrem em um circuito do controle operado entre diferentes instituições para tutela dos desviantes. Este estudo evidencia que, para evitar internações em hospitais psiquiátricos, além do fechamento destes, é preciso superar o paradigma psiquiátrico, sendo, para isso, necessárias as práticas de desinstitucionalização e na perspectiva da atenção psicossocial nos serviços de saúde mental abertos, territoriais e substitutivos.
Comparison of forest ecosystem services value evaluation methods: a case study of Sichuan Province, China
Authors: Jiang Yao , Yang Fan
Published: May 2022

ABSTRACT: The survival of human and sustainable development of the society both closely rely on forest ecosystem services. Employing two different methods, this paper based on benefit transfer method calculated the forest ecosystem services value of Sichuan province, China. The results showed that the total forest ecosystem services value had a steady rate of increase in Sichuan province from 2008 to 2018, and meanwhile, the different evaluation methods resulted in significant deviation of estimation outcomes. This paper considered the differences of biomass and socioeconomic development which were ignored in prior studies. The Carnegie-Ames-Stanford approach was employed to estimate the net primary productivity of different forest species. Further, the S type R. Pearl growth curve was employed to estimate people’s willingness and ability to pay for forest ecosystem services. This paper provided implications to help forest managers and policy makers pay additional attention to the evaluation systems choosing on forest ecosystem services value and the differences of biomass and socioeconomic development by using benefit transfer method method.
