Expressed Emotion, Mental Health, and Functioning in Families of Children with and without Asthma

Introduction: Expressed emotion (EE), the affective attitudes and behaviors of one toward another, can affect caregivers’ behaviors toward their child. Research examining associations between EE and child/family outcomes is mixed; these associations may be affected by other influences such as the presence of a chronic disease or parent mental health. In this study of families living in an urban area, we examined associations between EE and child outcomes (anxiety/depressive symptoms) and family functioning, with parent anxiety as a covariate. We evaluated child asthma status as a moderator in these associations as the presence of a chronic illness may strengthen the association between EE and child/family outcomes. Methods: 96 children (mean±SD age=8.83±2.03 years, 48.9% female, 92.6% African American; 47 with asthma) and their parents (81.3% annual household income\u3c$25,000) completed an observational study including interviews and questionnaires. Measures included the Multidimensional Anxiety Scale for Children (MASC), Children’s Depressive Symptoms Inventory (CDI), Self-Report Family Inventory (SFI), Generalized Anxiety Disorder scale (GAD-7), and Five-Minute Speech Sample (FMSS) coded for EE. To examine study aims, regression analyses were conducted using PROCESS macro version 3.1. Asthma status (yes/no) was examined as a moderator. Results: EE was associated with child anxiety symptoms, child depressive symptoms, and family functioning, controlling for parent anxiety symptoms (F(1,70) =6.74, p=.011; F(1,69) =7.803, p=.007; F(1,68) =8.637, p=.004). Asthma status did not moderate any of the associations. Conclusions: Results suggested that high levels of caregiver EE were associated with child mental health symptoms and family functioning, but asthma status did not moderate associations. It is possible that regardless of additional family demands related to asthma, EE is associated with child mental health and family functioning. Further examination into other systemic stressors that may moderate these associations is warranted, as well as the impact that minimizing parent anxiety might have on overall EE.https://scholarscompass.vcu.edu/gradposters/1075/thumbnail.jp

Critical Casimir force in 4^4He films: confirmation of finite-size scaling

We present new capacitance measurements of critical Casimir force-induced thinning of $^4$He films near the superfluid/normal transition, focused on the region below $T_{\lambda}$ where the effect is the greatest. $^4$He films of 238, 285, and 340 \AA thickness are adsorbed on N-doped silicon substrates with roughness $\approx 8 {\AA}$. The Casimir force scaling function $\vartheta$, deduced from the thinning of these three films, collapses onto a single universal curve, attaining a minimum $\vartheta = -1.30 \pm 0.03$ at $x=td^{1/\nu}=-9.7\pm 0.8 {\AA}^{1/\nu}$. The collapse confirms the finite-size scaling origin of the dip in the film thickness. Separately, we also confirm the presence down to $2.13 K$ of the Goldstone/surface fluctuation force, which makes the superfluid film $\sim 2 {\AA}$ thinner than the normal film.Comment: 4 pages, 3 figures, submitted to PR

BoltzTraP. A code for calculating band-structure dependent quantities

A program for calculating the semi-classic transport coefficients is described. It is based on a smoothed Fourier interpolation of the bands. From this analytical representation we calculate the derivatives necessary for the transport distributions. The method is compared to earlier calculations, which in principle should be exact within Boltzmann theory, and a very convincing agreement is found

Flux through a hole from a shaken granular medium

We have measured the flux of grains from a hole in the bottom of a shaken container of grains. We find that the peak velocity of the vibration, vmax, controls the flux, i.e., the flux is nearly independent of the frequency and acceleration amplitude for a given value of vmax. The flux decreases with increasing peak velocity and then becomes almost constant for the largest values of vmax. The data at low peak velocity can be quantitatively described by a simple model, but the crossover to nearly constant flux at larger peak velocity suggests a regime in which the granular density near the container bottom is independent of the energy input to the system.Comment: 14 pages, 4 figures. to appear in Physical Review

Monografia (graduação)—Universidade de Brasília, Faculdade de Comunicação, Comunicação Organizacional, 2013.A globalização, impulsionada pelas novas tecnologias e pela internet, provocou a quebra de paradigmas na comunicação e em diversas outras áreas das ciências humanas e exatas. Com isso, fez-se necessário estudar a mente moderna do consumidor e o mercado contemporâneo, bem como investigar as novas possibilidades de diálogos entre clientes e organizações. Em específico, este trabalho pretende entender como os sistemas colaborativos podem trazer soluções para as organizações, fundamentando-se em um estudo do caso Fiat Mio - o 1º carro colaborativo do mundo, baseado nas ideias e necessidades dos usuários. Para tanto, foram realizadas entrevistas virtuais que trouxeram diferentes pontos de vista do projeto, vindos do cliente, da organização e de parceiro na área de comunicação

Ressec??o extensa de glioblastomas e terapias adjuvantes como preditores de aumento da sobrevida global: revis?o sistem?tica

Glioblastoma multiforme ? o tumor maligno prim?rio mais comum do enc?falo, apresenta evolu??o r?pida e agressiva e, geralmente resulta em morte antes de um ano do diagn?stico. A necessidade de definir terapias que garantam maior sobrevida com qualidade a esses pacientes ? essencial. Material e M?todos: No per?odo de janeiro de 2017 e novembro de 2018 foi realizada revis?o sistem?tica nas bases de dados MEDLINE, Cochrane e LILACS com os buscadores e seus sin?nimos glioblastoma, neurocirurgia, radioterapia, quimioterapia e sobrevida. Foram encontrados 157 artigos dos quais 26 foram inclu?dos na revis?o. Resultados: A maioria dos estudos apresentou delineamento de coorte retrospectiva, sendo que 10 inclu?ram pacientes acima de 65 anos. A m?xima ressec??o cir?rgica poss?vel, com aplica??o do regime Stupp como terapia adjuvante, ainda ? a melhor op??o para todos os perfis de pacientes, por?m recomenda-se avaliar o estado cl?nico direcionando terapias individualizadas. Outros tratamentos citados necessitam de mais estudos para sua melhor avalia??o. Pacientes jovens apresentam maior benef?cio na maioria das vezes, quando comparados aos idosos. Conclus?o: Devido ao baixo poder estat?stico dos estudos, recomenda-se novas revis?es e estudos cl?nicos para definir terapias adequadas aos pacientes com glioblastoma

A promoção de circuitos curtos de comercialização de alimentos agroecológicos por organizações sociais durante a pandemia da Covid-19

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Agrárias. Curso de Agronomia.Por conta das medidas de restrição impostas pelos governos para conter a pandemia da Covid-19, pequenos agricultores tiveram dificuldades na comercialização da sua produção. Adicionalmente, o desemprego e a diminuição da renda aumentaram a insegurança alimentar e nutricional, especialmente de populações urbanas mais vulneráveis. Assim, a pandemia expôs as fragilidades dos sistemas alimentares atuais. O Agroecology Fund (AEF) é um fundo de apoio a projetos agroecológicos que lançou um fundo emergencial de resposta à pandemia. Este trabalho objetivou analisar os circuitos curtos de comercialização (CCC) promovidos por ONGs e organizações de agricultores apoiadas pelo AEF durante a pandemia da Covid-19. A pesquisa se tratou de um estudo de caso predominantemente qualitativo. Foi feita uma análise dos relatórios elaborados pelas organizações. Pelo menos 3613 agricultores foram apoiados por 21 iniciativas. Os CCC promovidos foram: compra e doação; compra e venda a preços solidários; mercados populares; feiras agroecológicas; mercados digitais; lojas e quiosques; lojas móveis e pop-ups; nós de consumo; e agricultura apoiada pela comunidade. As medidas de restrição foram a principal dificuldade na execução dos CCC, além dos desafios na logística e no uso das ferramentas digitaisDue to restriction measures imposed by governments to contain the Covid-19 pandemic, small farmers had difficulties in marketing their production. Additionally, unemployment and declining income have increased food and nutritional insecurity, especially among the most vulnerable urban populations. Thus, the pandemic exposed the weaknesses of current food systems. The Agroecology Fund (AEF) is a fund supporting agroecological projects that has launched an emergency fund in response to the pandemic. This work aimed to analyze the short food supply chains (SFSC) promoted by NGOs and farmers' organizations supported by the AEF during the Covid-19 pandemic. The research was predominantly a qualitative case study. An analysis of the reports prepared by the organizations was conducted. At least 3613 farmers were supported by 21 initiatives. The SFSC promoted were: procurement and donation; procurement and selling at solidarity prices; popular markets; agroecological fairs; digital markets; shops and kiosks; mobile and pop-up stores; consumption nodes; and community-supported agriculture. Restriction measures were the main difficulty in conducting the SFSC, in addition to the challenges in logistics and in the use of digital tool

Para tanto, primeiramente será abordado o surgimento e os aspectos mais relevantes da personalidade jurídica juntamente com a dignidade da pessoa humana, além de algumas diferenças existentes entre a capacidade e personalidade, então, será tratado a respeito dos Direitos da Personalidade. Posteriormente, após ser conceituada a figura do nascituro, serão abordados alguns direitos atualmente concedidos a este. Além disso, serão feitas breves observações de julgados a respeito do tema com o intuito de apontar os conflitos existentes entre diversos tribunais sobre as teorias da personalidade (especificamente a Teoria Natalista de um lado e a Concepcionista do outro). Por ultimo, será efetuado um direito comparado afim de demonstrar as diferenças entre diversos países a respeito do conteúdo aqui escrito, avaliando o Código Civil de cada país aqui estudado

Numerical study of the thermoelectric power factor in ultra-thin Si nanowires

Low dimensional structures have demonstrated improved thermoelectric (TE) performance because of a drastic reduction in their thermal conductivity, {\kappa}l. This has been observed for a variety of materials, even for traditionally poor thermoelectrics such as silicon. Other than the reduction in {\kappa}l, further improvements in the TE figure of merit ZT could potentially originate from the thermoelectric power factor. In this work, we couple the ballistic (Landauer) and diffusive linearized Boltzmann electron transport theory to the atomistic sp3d5s*-spin-orbit-coupled tight-binding (TB) electronic structure model. We calculate the room temperature electrical conductivity, Seebeck coefficient, and power factor of narrow 1D Si nanowires (NWs). We describe the numerical formulation of coupling TB to those transport formalisms, the approximations involved, and explain the differences in the conclusions obtained from each model. We investigate the effects of cross section size, transport orientation and confinement orientation, and the influence of the different scattering mechanisms. We show that such methodology can provide robust results for structures including thousands of atoms in the simulation domain and extending to length scales beyond 10nm, and point towards insightful design directions using the length scale and geometry as a design degree of freedom. We find that the effect of low dimensionality on the thermoelectric power factor of Si NWs can be observed at diameters below ~7nm, and that quantum confinement and different transport orientations offer the possibility for power factor optimization.Comment: 42 pages, 14 figures; Journal of Computational Electronics, 201
