Effect of OPC on Fiber Nonlinearities for Dense Soliton Optical Communication Medium
Authors: Kumar Ghanendra , Kumar Chakresh
Published: March 2020

This review paper scrutinizes the staging of dense wavelength division multiplexing soliton system in return to zero and non-return to zero format. In-line optical phase conjugator (OPC) is used to depreciate the power of four wave mixing (FWM). Destructive interference between both the halves of in-line OPC plummets the FWM power sturdily. This paper concludes with the indication that return-to-zero with OPC gives out better performance with FWM suppression.
Should Liberal-Egalitarians Support a Basic Income? An Examination of the Effectiveness and Stability of Ideal Welfare Regimes
Authors: Sirsch Jürgen
Published: March 2020

The article deals with the question whether an unconditional basic income (UBI) is part of an ideal liberal-egalitarian welfare regime. Analyzing UBI from an ideal-theoretical perspective requires a comparison of the justice performance of ideal welfare regimes instead of comparing isolated institutional designs. This holistic perspective allows for a more systematic consideration of issues like institutional complementarity. I compare three potential ideal welfare regimes from a liberal-egalitarian perspective of justice: An ideal social democratic regime, a mixed regime containing a moderate UBI and a maximal UBI regime where UBI replaces most of the welfare state. These regimes are evaluated with respect to three aspects of justice performance: the scope and neutrality of opportunities provided, institutional complementarities with a dynamic, globalized economy and the policy feedback effects on the political stability of liberal-egalitarian political coalitions. I conclude that the overall performance of a mixed regime is superior to the other regimes.

Published: March 2020

This study determines the length distribution, length– weight relationship, age, growth parameters, mortality rate, sex ratios, length at first maturity and reproduction of saddled seabream (Oblada melanura) collected monthly by fishermen around the Northern Aegean Sea between November 2017 and October 2018. The length–weight relationship was calculated asW=0.0091×L3.11(R2=0.95) and positive allometric growth was found. The condition factor and GSI varied between 0.81–1.58 and 0.01–9.61, respectively. The spawning season extended from May to July and peaked in June. Total lengths at 50% maturity were 18.97 cm for males and 18.83 cm for females. Parameters of the von Bertalanffy growth equation were:L∞ =29.91 cm,K=0.27 per year,t0=−0.82 year and age varied between 1 and 8. The instantaneous rates of total mortality (Z) and natural mortality (M) were 1.36 and 0.58 per year, respectively. Rates for fishing mortalityFand exploitationEwere 0.78 and 0.57 per year, respectively. The mean absolute fecundity (F) was 117 075±23 243 oocytes, ranging from 19130 to 470 132.
Demodex phocidi (Acariformes: Demodecidae) from Phoca vitulina (Carnivora: Phocidae) – the second observation in the world and a supplement to the species description
Authors: Izdebska Joanna N. , Rolbiecki Leszek , Cierocka Karolina , Pawliczka Iwona
Published: March 2020

The present study describes a finding of the demodecid mite Demodex phocidi in the seal Phoca vitulina in the Baltic Sea. This is the first identification in Europe and the second in the world. This is also the first observation of the Demodecidae family in the pinnipeds outside North America. A high density of demodecid mites was observed in the skin of the examined seal, but no symptoms of parasitosis were observed. Our findings also supplement the taxonomic description and morphometry of D. phocidi.

Published: March 2020

A total of 15Naviculataxa were recorded in epilithic communities occurring in seven rivers of Serbia, all of which are new to the diatom flora of Serbia. The most interesting of them areN. splendiculaandN. moskalii. When observingN. splendiculaspecimens under SEM, we noticed a characteristic silicate tongue in the center of raphe ends, which had not been previously reported in the available literature. The insufficiently researched distribution ofN. moskaliiand scarce autecological information on the taxon prompted us to provide new details about the species in this study. These findings clearly indicate the need for further comprehensive research that would provide new information on rare taxa.
Marked contrast in wind-driven upwelling on the southeastern Nova Scotia coast in July of two years differing in ENSO conditions
Authors: Scrosati Ricardo A. , Ellrich Julius A.
Published: March 2020

Upwelling occurs on several coasts of the world, but it has mostly been studied on eastern ocean boundaries. We investigated upwelling on a western ocean boundary for which limited information exists. Using daily in-situ data on sea surface temperature (SST), we found a marked contrast in coastal cooling between July 2014 (pronounced) and July 2015 (weak) at two locations 110 km apart on the Atlantic coast of Nova Scotia, Canada. These findings are consistent with a marked interannual difference in wind-driven upwelling. On the one hand, southwesterlies (which cause upwelling on this coast) were more frequent in July 2014 than in July 2015. On the other hand, Bakun’s upwelling index (which is based on wind data and geographic information) indicated that coastal upwelling was more common and intense in July 2014 than in July 2015, while the reverse was true for downwelling. Interestingly, a strong El Niño event occurred in July 2015, while no El Niño (or La Niña) conditions happened in July 2014. In a recent book evaluating upwelling systems around the world, the system that is the focus of the present study was not included. Therefore, our findings should stimulate future research on upwelling on the Atlantic Canadian coast, in that way helping to further develop the knowledge base for western ocean boundaries.

Published: March 2020

Mitochondrial fission catalyzed by dynamin-related protein 1 (Drp1) is necessary for mitochondrial biogenesis and maintenance of healthy mitochondria. However, excessive fission has been associated with multiple neurodegenerative disorders, and we recently reported that mice with smaller mitochondria are sensitized to ischemic stroke injury. Although pharmacological Drp1 inhibition has been put forward as neuroprotective, the specificity and mechanism of the inhibitor used is controversial. Here, we provide genetic evidence that Drp1 inhibition is neuroprotective. Drp1 is activated by dephosphorylation of an inhibitory phosphorylation site, Ser637. We identify Bβ2, a mitochondria-localized protein phosphatase 2A (PP2A) regulatory subunit, as a neuron-specific Drp1 activatorin vivo. Bβ2 KO mice of both sexes display elongated mitochondria in neurons and are protected from cerebral ischemic injury. Functionally, deletion of Bβ2 and maintained Drp1 Ser637 phosphorylation improved mitochondrial respiratory capacity, Ca2+homeostasis, and attenuated superoxide production in response to ischemia and excitotoxicityin vitroandex vivo. Last, deletion of Bβ2 rescued excessive stroke damage associated with dephosphorylation of Drp1 S637 and mitochondrial fission. These results indicate that the state of mitochondrial connectivity and PP2A/Bβ2-mediated dephosphorylation of Drp1 play a critical role in determining the severity of cerebral ischemic injury. Therefore, Bβ2 may represent a target for prophylactic neuroprotective therapy in populations at high risk of stroke.

SIGNIFICANCE STATEMENTWith recent advances in clinical practice including mechanical thrombectomy up to 24 h after the ischemic event, there is resurgent interest in neuroprotective stroke therapies. In this study, we demonstrate reduced stroke damage in the brain of mice lacking the Bβ2 regulatory subunit of protein phosphatase 2A, which we have shown previously acts as a positive regulator of the mitochondrial fission enzyme dynamin-related protein 1 (Drp1). Importantly, we provide evidence that deletion of Bβ2 can rescue excessive ischemic damage in mice lacking the mitochondrial PKA scaffold AKAP1, apparently via opposing effects on Drp1 S637 phosphorylation. These results highlight reversible phosphorylation in bidirectional regulation of Drp1 activity and identify Bβ2 as a potential pharmacological target to protect the brain from stroke injury.
Predicting School-Aged Cognitive Impairment in Children Born Very Preterm
Authors: Erdei Carmina , Austin Nicola C. , Cherkerzian Sara , Morris Alyssa R. , Woodward Lianne J.
Published: March 2020

BACKGROUND AND OBJECTIVES:

Children born very preterm (VPT) are at high risk of cognitive impairment that impacts their educational and social opportunities. This study examined the predictive accuracy of assessments at 2, 4, 6, and 9 years in identifying preterm children with cognitive impairment by 12 years.

METHODS:

We prospectively studied a regional cohort of 103 children born VPT (≤32 weeks’ gestation) and 109 children born term from birth to corrected age 12 years. Cognitive functioning was assessed by using age-appropriate, standardized measures: Bayley Scales of Infant Development, Second Edition (age 2); Wechsler Preschool and Primary Scale of Intelligence (ages 4 and 6); and Wechsler Intelligence Scale for Children, Fourth Edition (ages 9 and 12).

RESULTS:

By 12 years, children born VPT were more likely to have severe (odds ratio 3.9; 95% confidence interval 1.1–13.5) or any (odds ratio 3.2; 95% confidence interval 1.8–5.6) cognitive impairment compared with children born term. Adopting a severe cognitive impairment criterion at age 2 under-identified 44% of children born VPT with later severe impairment, whereas a more inclusive earlier criterion identified all severely affected children at 12 years. Prediction improved with age, with any delay at age 6 having the highest sensitivity (85%) and positive predictive value (66%) relative to earlier age assessments. Inclusion of family-social circumstances further improved diagnostic accuracy.

CONCLUSIONS:

Cognitive risk prediction improves with age, with assessments at 6 years offering optimal diagnostic accuracy. Intervention for children with early mild delay may be beneficial, especially for those raised in socially disadvantaged family contexts.

Published: March 2020

A previously healthy 9-year-old immigrant girl from Mexico was evaluated in the emergency department (ED) with one week of fatigue, fevers, rhinorrhea, and cough. She initially presented to her primary pediatrician, where a complete blood count revealed neutropenia, prompting referral to the ED. In the ED, she was found to be influenza A–positive. Because of dehydration, she received intravenous fluids and was admitted to the pediatric hospital medicine service. After 2 days, influenza symptoms improved, and oral intake increased. However, she was noted to have decreased bilateral lower-extremity strength, absent Achilles reflexes, decreased lower-extremity sensation and proprioception, a positive result on the Romberg sign, and abnormal heel-to-shin testing results. These findings prompted an urgent neurology consultation. After extensive imaging, laboratory evaluation, and further consultations, a diagnosis was established.
Simultaneous quantification of cortisol and cortisone in serums and saliva from depressive patients by supported liquid extraction coupled to HPLC–MS/MSs
Authors: Chen Binbin , Lyu Haiyan , Xu Xiangzhen , Wang Chen
Published: March 2020

Cortisol and cortisone are 2 important glucocorticoids produced in the human hypothalamus–pituitary–adrenal (HPA) axis that respond to stress. An analytical method to determinate cortisol and cortisone in serum and saliva using high-performance liquid chromatography–tandem mass spectrometry following a supported liquid extraction (SLE) was developed. Serum and saliva samples of 0.2 mL were extracted by SLE three times using 0.4 mL of methyl tert-butyl ether each time. The chromatographic separation was obtained on an Agilent Poroshell column using a 0.01% formic acid buffer and acetonitrile (60:40, v/v) as the solvent with a flow rate of 0.3 mL/min. Optimized quantitative mass transitions for cortisol, cortisone, and cortisone d-4 were 363.2/121.0 (m/z), 361.2/163.1 (m/z), and 367.1/270.7 (m/z), respectively. The method validation was achieved according to regulatory guidance. The lower limit of quantification (LLOQ) in serum were 2 ng/mL for cortisol and 1 ng/mL for cortisone, and the LLOQ in saliva were 0.1 ng/mL for cortisol and 0.2 ng/mL for cortisone. The developed method showed convenient and efficient extraction, a lower LLOQ, and a short running time. Modest correlations between serum and saliva cortisol and cortisone concentrations were found. The method was successfully applied in assessing the HPA condition of patients with depressive disorders.
Vibrational Study of the Hydrogen Adsorption on the Missing Row Platinum (110) Surface
Authors: Hanh Tran Thi Thu , Hoa Nguyen Van
Published: March 2020

The hydrogen vibration was investigated to analyze its affect on the hydrogen adsorption on the missing row platinum surface (H/Pt(110)-(1\(\times\)2) model) in the ultrahigh vacuum (UHV). The density functional theory (DFT) combined with the approximation oscillation of the hydrogen atom on the surface was used. When the hydrogen coverage ΘH on the surface is 100% (\(\Theta\) = 1 ML), and taking into account the vibrational effect, the bond formed at the edge of the first layer (short bridge) is the most stable site. The vibrational effect on the adsorption model H/Pt(110)-(1\(\times\)2) is significant.
Dynamics of Electroweak Phase Transition in the 3-3-1-1 Model
Authors: Dinh Thanh Binh , Vo Quoc Phong , Ngoc Long Hoang
Published: March 2020

The bubble nucleation in the framework of 3-3-1-1 model is studied. Previous studies show that first order electroweak phase transition occurs in two periods. In this paper we evaluate the bubble nucleation temperature throughout the parameter space. Using the stringent condition for bubble nucleation formation we find that in the first period, symmetry breaking from \(SU(3)\rightarrow SU(2)\), the bubble is formed at the nucleation temperature $T=150$ GeV and the lower bound of the scalar mass is 600 GeV. In the second period, symmetry breaking from \((SU(2)\rightarrow U(1)\), only subcritical bubbles are formed. This constraint eliminates the electroweak baryon genesis in the second period of the model.

Published: March 2020

The synthesis of graphene (Gr) - gold (Au) nanoparticle (NP) composite was achieved using continuous ultraviolet wave exposure. The functional groups were investigated with FT-IR spectra. From the Raman spectra, D-band and G-band of graphene were identified. As a result, the uniform deposition of nanometer-sized Au NPs on the graphene sheets was observed from the field emission scanning electron microscope (FE-SEM) images. The photodegradation of methylene blue in aqueous solutions is studied using various photocatalysts, including neat TiO2, Gr/TiO2 and Gr-Au/TiO2 composites. The Gr weight ratio in this research is 2%. The Gr2%-Au0.1%/TiO2 composite had the highest photoactivity.
Quantum Transport Through a ``Charge" Kondo Circuit: Effects of Weak Repulsive Interaction in Luttinger Liquid
Authors: Nguyen Thanh Thi Kim , Kiselev Mikhail N.
Published: March 2020

We investigate theoretically quantum transport through the ``charge" Kondo circuit consisting of the quantum dot (QD) coupled weakly to an electrode at temperature \(T+\Delta T\) and connected strongly to another electrode at the reference temperature \(T\) by a single-mode quantum point contact (QPC). To account for the effects of Coulomb interaction in the QD-QPC setup operating in the integer quantum Hall regime we describe the edge current in the quantum circuit by Luttinger model characterized by the Luttinger parameter \(g\). It is shown that the temperature dependence of both electric conductance \(G\propto T^{2/g}\) and thermoelectric coefficient \(G_T\propto T^{1+2/g}\) detours from the Fermi-liquid (FL) theory predictions. The behaviour of the thermoelectric power \(S=G_T/G\propto T\) in a regime of a single-channel Kondo effect is, by contrast, consistent with the FL paradigm. We demonstrate that the interplay between the mesoscopic Coulomb blockade in QD and weak repulsive interaction in the Luttinger Liquid \(g=1-\alpha\) \((\alpha \ll 1)\) results in the enhancement of the thermopower. This enhancement is attributed to suppression of the Kondo correlations in the ``charge" circuit by the destructive quantum interference effects.
Acelerador forte e concavidade da função consumo em modelos neokaleckianos: rediscutindo o crescimento liderado pelos salários
Authors: Moreira Vivian Garrido
Published: March 2020

Resumo Este ensaio propõe uma alternativa de generalização, sob certas condições, do conceito de acelerador forte, no sentido dado a ele dentro do modelo crítico de Bhaduri e Marglin (1988 e 1990), a partir de uma função consumo côncava. Com base nisso, demonstra que a possibilidade de um regime de crescimento liderado pelos salários deixa de ser um caso eventual, tonando-se consideravelmente provável. Simetricamente, torna improvável a possibilidade de ocorrência de compressão dos lucros (profit-squeeze). O texto também analisa criticamente o próprio modelo canônico de Bhaduri e Marglin, apresentando questionamentos sobre sua clareza enquanto fonte de crítica a uma série de modelos de crescimento neokaleckianos que o antecedem.
Choques de oferta e política monetaria na economia brasileira: uma análise do impacto dos preços das commodities na inflação entre 2002 e 2014
Authors: Carrara Aniela Fagundes , Barros Geraldo Sant’Ana de Camargo
Published: March 2020

Resumo Este estudo investiga como os choques de oferta, originados pelos preços das commodities, têm impactado na inflação brasileira e como e com que eficiência a política monetária do país tem reagido. Para tanto, foi estimado um modelo semiestrutural contendo uma curva de Phillips, uma curva IS e duas versões da Função de Reação do Banco Central. O método de estimação empregado foi o de Autorregressão Vetorial com Correção de Erro (VEC) na sua versão estrutural. Os resultados sugerem que a taxa de inflação brasileira tem um componente de indexação importante, mas é também influenciada pela expectativa que o mercado forma a seu respeito e pelo comportamento dos preços do lado da oferta, que também exercem certo impacto na expectativa de inflação.
The spatial organization of oil and gas investments in South America: an analysis based on communities
Authors: Françoso Mariane Santos , Breul Moritz , Hiratuka Celio
Published: March 2020

Abstract The global economy is organized in value chains, spatially and functionally fragmented. Despite this dispersion, the administrative activities of these chains continue to be concentrated in some cities, which play an important role in certain chains, because they concentrate companies and economic flows. The research on value chains has not focused on the city level and has adopted mainly case studies as the methodological approach. Considering this, we apply a network methodology to analyse the powerful cities in the South American oil and gas investment network, including the attributes that explain this position and the spatial extent of it. To perform this analysis, we use data on green and brownfield investments. Our results indicate that Rio de Janeiro is the most central city in this network, but its action is mainly concentrated in Brazil. This work seeks to contribute mainly to the methodological development of the studies in the area.

Abstract This study evaluated the association between polymorphisms in genes encoding estrogen receptors 1 (ESR1) and 2 (ESR2), vitamin D receptor (VDR) and in microRNA17 (which binds to ESR1 and VDR) with persistent apical periodontitis (PAP) after the endodontic treatment. We included 162 patients who completed endodontic treatment at least one year ago and presented apical periodontitis at the beginning of the root canal therapy. Clinical and radiographic exams were performed to evaluate the presence of PAP or healthy periradicular tissues (healed). Saliva samples were collected as a genomic DNA. The genotyping of ESR1 (rs2234693 and rs9340799), ESR2 (rs1256049 and rs4986938), VDR (rs739837 and rs2228570) and miRNA17 (rs4284505) were performed by real-time PCR. Chi-square test was used to the distribution of genotype and allele frequencies. Haplotype analysis was also performed. Eighty-nine patients were included in the “healed” group and 73 in the “PAP” group. No association was found between the allelic and genotypic polymorphisms studied and PAP (p>0.05). Haplotype analysis also did not demonstrated an association (p>0.05). In conclusion, the genetic polymorphisms in ESR1, ESR2, VDR and miRNA17 are not associated with PAP.

Abstract The objective of this study was to investigate the effects of low-level laser therapy (LLLT) and cigarette smoke on alveolar socket osteoclastogenesis signaling after tooth extraction, in rats. Sixty male Wistar rats were randomly assigned to four groups with 15 animals each: Control Group (with right maxillary molar extraction - ME), Experimental I (with ME and LLLT), Experimental II (with ME and cigarette smoke) and Experimental III group (with ME, LLLT and cigarette smoke). Euthanasia was performed at 3, 7 and 14 days postoperative. qRT-PCR was used to evaluate expression of Tnfrsf11a (RANK), Tnfsf11 (Rankl) and Tnfrsf11b (OPG). Data were submitted to statistical analysis using two-way ANOVA followed by Bonferroni test (α=0.05). There was an upregulation of RANK, RANKL and OPG genes over all the time of healing in Exp I group compared to control group. Exp II group showed a decreased expression of all genes over time, whereas Exp III genes expression were higher than Exp II values but lower than Control and Exp I values over time. The results of this study concluded that the LLLT had a positive effect, whereas cigarette smoke had a negative effect on RANK, RANKL and OPG gene expression in bone remodeling process.

Abstract This study assessed bibliometric characteristics of all articles published in Brazilian Dental Journal (BDJ) in its 30 years of existence (1990-2019) and factors associated with citation rates. A document search was carried out in Scopus in December, 2019 and information about the articles were exported, including citations. Type of study and main subject in each article were categorized. Number of citations was categorized in tertiles. Logistic regression models were used to assess the association between variables related to articles’ characteristics and number of citations. In 30 years, 1705 articles were published and 18507 citations received, with average 57 articles and 334 pages published yearly and 10.9 cites/doc. The most frequent types of study were laboratorial (63%), clinical (18.5%), and case reports (11%); the main subjects were dental materials (21.6%), endodontics (19.3%), and oral pathology/stomatology (13.1%). Most articles had origin in Brazil (90%), followed by USA (4.6%) and UK (1.5%). Aside from BDJ, Journal of Endodontics (3.5%) and International Endodontic Journal (2.2%) were journals that most often cited BDJ. Main origins of citations were Brazil (36.7%), USA (10.6%), and India (9%). Older articles had higher odds to be highly cited (12% increase/year), longer articles had lower odds (9% decrease/page). Narrative reviews and epidemiological studies were associated with more citations and systematic reviews with less citations. In conclusion, BDJ covered many subjects and study types in 30 years, showing increased growth in international audience. The journal may be regarded as one of the leading Brazilian journals in dentistry published in English.
Gestão democrática na mesorregião Oeste Maranhense: enfoques e destaques nas leis dos Sistemas Municipais de Educação
Authors: Cardozo Maria José Pires Barros , Colares Maria Lília Imbiriba Sousa
Published: March 2020

RESUMO O presente artigo analisa questões referentes aos Sistemas Municipais de Educação (SME) na Mesorregião Oeste Maranhense, em especial o princípio da gestão democrática nos municípios que institucionalizaram os seus SME. As questões e inferências aqui apresentadas decorrem de pesquisa bibliográfica e documental realizada no pós-doutoramento do Programa de Pós-graduação em Educação da Universidade Federal do Oeste do Pará (Ufopa). Discorre-se sobre alguns aspectos e questões teóricas e legais que fundamentam a concepção de sistema educacional e a gestão democrática como premissas que orientam a criação dos SME. Infere-se que, embora os municípios gozem da prerrogativa de criarem seus SME, na mesorregião Oeste Maranhense, apenas 8 dos 52 institucionalizaram seus sistemas com base em leis específicas, abstendo-se dos dispositivos legais que dispõem sobre a definição e normatização de legislação específica e diretrizes educacionais que possibilitem a ampliação e fortalecimento dos espaços e mecanismos de participação, consolidando a gestão democrática da educação municipal.
Monitoramento e Avaliação dos Planos Decenais de Educação: a produção do conhecimento no Brasil
Authors: Aranda Maria Alice de Miranda , Rodrigues Evally Solaine de Souza , Militão Sílvio Cesar Nunes
Published: March 2020

RESUMO O escopo principal deste trabalho consiste em realizar um balanço sobre a produção do conhecimento referente ao monitoramento e avaliação dos planos decenais de educação, no período de 2001 a 2017, aqui compreendidos como Plano Nacional de Educação (PNE), Plano Estadual de Educação (PEE) e Plano Municipal de Educação (PME). Para esse levantamento, não se fez distinção entre as duas gerações de Planos, surgidas após o Brasil democrático de 1988 (PNE 2001-2010 e PNE 2014-2024 e os respectivos planos subnacionais) visto que se julgou relevante alcançar maior abrangência na pesquisa, a fim de contribuir com a produção do conhecimento acerca da temática em tela. De abordagem quali-quantitativa, este artigo valeu-se de pesquisa exploratória e bibliográfica e contemplou a utilização das seguintes bases de dados: a) Portal de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); b) Anais resultantes das reuniões nacionais da Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPED); e c) bases de dados da Biblioteca Científica Eletrônica Online (Scielo Brasil). Os resultados mostram que ainda é muito escassa a produção do conhecimento nacional voltada aos planos decenais de educação, sobretudo se considerado o foco exclusivo no monitoramento e avaliação dos Planos. Conclui-se, portanto, que tal foco de abordagem constitui-se num campo aberto e fértil para novas pesquisas.
Repercussões da nova gestão pública na gestão da educação: um estudo da rede estadual de Goiás
Authors: Marques Luciana Rosa
Published: March 2020

RESUMO O modelo da Nova Gestão Pública (NGP) tem se tornado hegemônico no Brasil. Calcado em metas, resultados e em avaliações de larga escala, tem sido adotado por vários estados no país. Seus preceitos têm sido implantados também na educação. Este estudo busca verificar quais as repercussões da NGP na gestão da educação na rede pública estadual de Goiás, estado que vem se destacando pelos bons resultados alcançados em avaliações de larga escala. Tomando por base os construtos da Teoria do Discurso, proposta por Ernesto Laclau e seus seguidores, a pesquisa foi realizada a partir de entrevistas com os dirigentes das escolas de maior e menor do Índice de Desenvolvimento da Educação Básica (IDEB) do estado, do sindicato dos profissionais de educação e da secretaria de educação, além da análise das diretrizes governamentais. Verificamos que a NGP é hegemônica na política educacional do estado, constituindo-se como um ponto nodal. No entanto, a gestão democrática também é fulcral no discurso dos entrevistados, podendo ser considerada também como um ponto nodal.

Published: March 2020

Resumo O objetivo deste artigo é identificar as produções científicas sobre o acesso e utilização de serviços odontológicos por gestantes. Foi realizada uma revisão integrativa de literatura com busca nas bases de dados BVS e MEDLINE/PubMed. Na base BVS os descritores foram: “acesso aos serviços de saúde”, “saúde bucal” e “gestantes”, e na PubMed: “Health services accessibility”, “oral health” e “pregnant women”, associados entre si pelo operador booleano AND. Foram encontrados cinco estudos que preencheram os critérios de inclusão e exclusão, sendo sistematizados em duas categorias empiricas e co-relacionadas: número expressivo de gestantes que não realizam o pré-natal odontológico e importância de medidas educativas que sinalizem a necessidade de receberem acompanhamento odontológico durante as consultas de pré-natal. Existe a necessidade de mais estudos, para embasar políticas de saúde pública que contemplem esta temática. As pesquisas existentes demonstram baixa adesão ao pré-natal odontológico e que os principais fatores observados como complicadores do acesso e utilização dos serviços odontológicos foram os relacionados aos aspectos socioeconômicos, culturais e educacionais.

Published: March 2020

Resumen Para el control del dengue es esencial el reconocimiento de los determinantes de los conocimientos, actitudes y prácticas (CAP), los cuales podrían estar condicionados por las experiencias y percepciones de la población a riesgo. El propósito de este artículo es estimar la asociación entre la percepción del riesgo y la experiencia de dengue con los CAP sobre dengue, en una población endémica de Colombia. Estudio analítico de corte transversal y muestreo probabilístico, polietápico por conglomerados. Como medidas de asociación se estimaron las razones de prevalencia ajustadas (RPa) usando modelos de regresión. Se entrevistaron 206 familias. El 7% saben que la enfermedad del dengue es causada por un virus y menos del 40% reconocen otros síntomas diferentes a la fiebre. El 31% practica la eliminación de criaderos y el 58% fumiga como estrategias de control. El 73% percibe el riesgo de dengue. Se estimó una asociación significativa de la percepción del riesgo de dengue con el conocimiento sobre el vector (RPa = 3,32 IC95% 1,06-10,36). Además, el antecedente de diagnóstico de dengue se asoció con la actitud frente a su control (RPa = 1,61 IC95% 1,09-2,37).

Authors: Ferreira João Paulo , Miskolci Richard
Published: March 2020

Resumo Este artigo analisa as mudanças e continuidades nos critérios de busca de parceiros por homens homossexuais a partir do impacto da epidemia de HIV-aids na cidade de São Paulo. Assim, compara dois momentos históricos distintos: entre 1979 e 1981 (pré-epidemia) e 2015 a 2017 (pós-epidemia). No primeiro período, a fonte incorporou 120 classificados recolhidos do jornal Lampião da Esquina e no segundo período, foram analisadas as preferências e os critérios acionados na busca por parceiros realizada com o uso de aplicativos geolocalizados, a partir de 120 perfis on-line. Os dados permitem afirmar que, já na virada da década de 1970 para a de 1980, existia a busca pelo “discreto” enquanto o pânico sexual criado em meio ao período mais mortal da epidemia de AIDS impulsionou o uso de Internet por homossexuais em busca de parceiros com menor probabilidade de estarem contaminados com o HIV, o “fora do meio (gay)”. Desde então, a busca pelo “discreto e fora do meio” se consolidou moldando ideais corporais e de conduta que regem o atual mercado sexual on-line em que se insere parte dos homossexuais paulistanos.
Amistad, hiperconexión y educación: un análisis conceptual a partir de Aristóteles
Authors: Sánchez-Rojo Alberto , Ahedo-Ruiz Josu
Published: March 2020

Resumen Hoy en día habitamos un mundo de conexión permanente donde nuestra atención es constantemente reclamada de manera simultánea por múltiples frentes. Esto nos conduce a relaciones de amistad meramente superficiales. A través de un detallado análisis conceptual, este artículo muestra hasta qué punto esto es cierto y en qué medida merece la pena, desde un punto de vista educativo, que los jóvenes aprendan a vivir sus relaciones de amistad con algo más de profundidad. Para ello, primeramente, se recurre al actualmente olvidado concepto aristotélico de amistad perfecta. Se trataba de un tipo de amistad profunda y esencial que Aristóteles distinguía de otros tipos más superficiales y accidentales. En segundo lugar, se analiza profusamente el estado de cosas actual. A través de varios estudios tanto teóricos como empíricos se demuestra que hoy en día carecemos del tiempo suficiente del que sería necesario disponer a fin de construir vínculos de amistad profundos y no superficiales. En tercer lugar, señalamos la manera en la que el campo educativo ha sido influido por la inercia del contexto. Esto ha llevado a que la escuela y también las familias sólo potencien amistades superficiales. Finalmente, se concluye que la amistad perfecta está directamente relacionada con la moral. De esta forma, si queremos que las futuras generaciones crezcan como sujetos morales, es importante dotarles del tiempo necesario para que cultiven amistades perfectas.

Background

Peptide receptor radionuclide therapy (PRRT) is effective for treating midgut neuroendocrine tumors (NETs); however, incorporation of PRRT into routine practice in the U.S. is not well studied. Herein we analyze the first year of PRRT implementation to determine tolerance of PRRT and factors that increase risk of PRRT discontinuation.

Materials and Methods

Medical records were reviewed and data were abstracted on all patients with NETs scheduled for PRRT during the first year of PRRT implementation at a U.S. NET referral center (August 2018 through July 2019). Logistic regression was used to identify factors associated with PRRT discontinuation.

Results

Fifty-five patients (56% male) were scheduled for PRRT over the study period. The most common primary NET location was small bowel (47%), followed by pancreas (26%), and 84% of the NETs were World Health Organization grade 1 or 2. The cohort was heavily pretreated with somatostatin analog (SSA) therapy (98%), non-SSA systemic therapy (64%), primary tumor resection (73%), and liver-directed therapy (55%). At the time of analysis, 52 patients completed at least one PRRT treatment. Toxicities including bone marrow suppression and liver function test (LFT) abnormalities were comparable to prior publications. Eleven patients (21%) prematurely discontinued PRRT because of toxicity or an adverse event. Pretreatment LFT abnormality was associated with increased risk of PRRT cancellation (odds ratio: 12; 95% confidence interval: 2.59–55.54; p < .001).

Conclusion

PRRT can be administered to a diverse NET population at a U.S. NET referral center. Baseline liver function test abnormality increases the likelihood of PRRT discontinuation.

Implications for Practice

Peptide receptor radionuclide therapy (PRRT) can be successfully implemented at a U.S. neuroendocrine tumor (NET) referral center in a NET population that is diverse in tumor location, grade, and prior treatment history. Toxicity and adverse effects of PRRT are comparable to prior reports; however, 21% of individuals prematurely discontinued PRRT. Patients with baseline liver function test abnormalities were more likely to discontinue PRRT than patients with normal liver function tests, which should be taken into consideration when selecting treatment options for NETs.
Performance of anchor in sand with different forms of geosynthetic reinforcement
Authors: Kishor Kumar V. , Ilamparuthi K.
Published: March 2020

This article investigates the uplift resistance of a model anchor embedded in sand by varying its density at four embedment depths (L/D = 1, 2, 3, and 4). Such different configurations of geosynthetic reinforcement as single-layer planar, double-layer planar, geocell, and geocell with basal reinforcement were used and the results were compared. The inclusion of reinforcement in all configurations led to greater values of the peak and residual pullout load than the anchor in sand at different densities. Of the reinforcement configurations used, a geocell placed at the top of the anchor was the most efficient. The shape of the uplifted soil mass by the anchor is a frustum of a cone with an apex angle approximately equal to ϕ′ of sand both in the sand bed without and with a geocell-encapsulated layer, except for the enlarged size of the uplifted mass for the anchor in the geocell-reinforced bed. The enlarged size is attributed to the wide slab response of the combined geocell composite anchor system. The hyperbolic stress–strain relation was used to predict the pre-peak phase of the load–displacement response and the relation thus obtained compared well with experimental data irrespective of the embedment ratio and relative densities of the sand bed.
Cyclic swell–shrink behaviour of an expansive soil treated with a sulfonated oil
Authors: Soltani Amin , Raeesi Ramin , O'Kelly Brendan C.
Published: March 2020

The effects of a sulfonated oil (SO) stabiliser on the swell–shrink properties of an expansive soil were investigated through cyclic wetting–drying tests. The cyclic wetting–drying action led to the reconstruction of the soil microstructure by inducing clay particle aggregation. Accordingly, the greater the number of applied cycles, the lower the swell–shrink potential up to the fourth cycle, beyond which the swelling and shrinkage strains attained elastic equilibrium. At any given cycle, the tendency for swell–shrink reduction was in favour of the SO concentration up to 0·75%, beyond which the excess SO molecules self-associated in the form of aggregates, thereby acting as a ‘lubricant’ rather than a clay-stabilising agent. As a result of SO treatment, the accumulated axial strain progressively transitioned towards a desirable, ‘neutral’ state, with 0·75% SO exhibiting the highest resistance against cyclic wetting–drying. For any given SO concentration, the equalised void ratio–moisture content curves for wetting and drying followed the same S-shaped path, further corroborating that the swelling and shrinkage processes, on achieving elastic equilibrium, become reversible. The shrinkage and liquid limits indicated a progressive transition towards a desirable, aggregated fabric, with 0·75% SO identified as the optimum concentration.
Recomendações para a Realização de Grupos Focais na Pesquisa Qualitativa
Authors: Souza Luciana Karine de
Published: March 2020

O presente artigo teórico discute o papel do grupo focal na pesquisa qualitativa para além de seu uso como técnica em sessão única. Ele é apresentado como método, capaz de gerar contribuições relevantes e frutíferas. São reunidas e comparadas as principais contribuições de textos brasileiros selecionados, principalmente em virtude da singularidade na apresentação de o que sejam grupos focais. São esclarecidas as diferenças entre grupo focal e entrevista em grupo, uso em pesquisa, preparação, registro, roteiro, amostragem, estrutura, moderador, condução do debate, elementos pré- e pós-debate, dentre outros aspectos. Dois autores estrangeiros tradicionais, David Morgan e Rosaline Barbour, são acrescidos ao debate, contribuindo com posições semelhantes e distintas sobre a finalidade e características do grupo focal. Experiências com a aplicação, o ensino e o treinamento do método fundamentam as considerações traçadas. A intenção é que tenham sido esclarecidas dúvidas e dissolvidas preconcepções acerca do uso de grupo focal na pesquisa, focalizando a abordagem qualitativa, mas com recomendações que devem acompanhar sua aplicação na abordagem quantitativa.
Problematizando as Práticas de Criminalização dos Movimentos Sociais: uma Análise Documental
Authors: Santos Igor do Carmo , Lemos Flávia Cristina Silveira
Published: March 2020

Este trabalho teve como objetivo fazer um levantamento, revisão e análise da literatura acerca do tema “Criminalização dos Movimentos Sociais”. Foram utilizadas para a análise dissertações coletadas no ano de 2013 encontradas sobre esse tema no banco de dados da Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). Para a análise das dissertações foram utilizadas as pistas deixadas pelo trabalho realizado por Michel Foucault através de suas ferramentas arqueológicas e genealógicas de análise que nos forneceu a possibilidade de uma crítica e uma problematização das práticas discursivas (saber) e não discursivas (poder e subjetivação) que atravessam e compõem os trabalhos analisados, guiado pela visão de uma história descontínua que deflagra acontecimentos em sua singularidade. Verificamos que as séries recortadas das dissertações trazem à mídia, a justiça, a polícia e o governo como principais elementos de uma prática de criminalização dos movimentos sociais, sem esquecer-se de apontar as resistências promovidas por esses grupos contra esse processo.
Social Creation and Media Publicity
Authors: Svitich Luisa , Smirnova Olga , Shkondin Mikhail
Published: March 2020

The article discusses the problems of formation of a model of informational impulse-wave interaction of society and mass media within a system of social creativity, which were suggested by A.P. Sukhodolov and co-authors, as well as characterizes systematic properties of media publicity as a factor of social creativity on the current civilization stage. Media publi­city is analyzed as an informational phenomenon closely related to social art, to creativity of social practice, to interaction within society providing unity of thought and action, to intellectual interaction within a society, to enrichment of the intellect of audience groups based on continuously updated media reality in the informational potential of mass media.
