Published: April 2022

Objetivo da pesquisa: analisar as dinâmicas da agenda do aborto no contexto brasileiro, considerando a interação entre a agenda legislativa, da mídia e do STF entre 1988 e 2020.
Enquadramento teórico: adota-se a Teoria do Equilíbrio Pontuado para analisar a atenção dada à questão do aborto nos fóruns da Câmara dos Deputados, no Senado, no STF e na mídia, bem como a imagem expressa pelos atores envolvidos.
Metodologia: emprega-se uma abordagem longitudinal, considerando-se quatro elementos teórico-analíticos: atenção, imagem, atores e fóruns de política. São analisados a quantidade e o tom (contrário, favorável ou neutro) de projetos de lei (n=401), pronunciamentos de senadores (n=298), de deputados (n=1176), de atores em audiências públicas no Senado (n=44) e no STF (n=79) e, da mídia, uma amostra de atores citados (n=394) em notícias de capa do Estadão, Folha de São Paulo e O Globo.
Resultados: apresentam-se os resultados cronologicamente, destacando-se a estabilidade na política do aborto no Congresso, onde prevalece o tom contrário e poucos projetos de lei são aprovados, ao passo que pontuações (mudanças) têm ocorrido via STF, algo constatado pela agenda legislativa e midiática.
Originalidade: adiciona-se o fórum do STF à análise da agenda, órgão do judiciário que tem interpretado questões constitucionais relacionadas ao aborto e realizado audiências públicas com atores nacionais e estrangeiros.
Contribuições teóricas e práticas: consolidam-se 33 anos da agenda do aborto, com informações relevantes para parlamentares, atores envolvidos e para o cidadão, trazendo para o debate a questão da judicialização da política com mudanças via STF. Ponderam-se limitações e pesquisas futuras.

Published: April 2022

- Objetivo da pesquisa: analisar a influência da escolha escolar sobre a eficiência das escolas públicas de ensino fundamental no Brasil.
- Enquadramento teórico: a teoria da escolha escolar consiste em aplicações da hipótese de Tiebout na educação, sendo a competição propulsionadora da escolha escolar das famílias.
- Metodologia: Tomou-se como unidade de análise, em cada município, o conjunto de escolas classificadas quanto à rede de ensino (estadual ou municipal) e à oferta de anos do ensino fundamental (todos, só os iniciais ou só os finais). Construiu-se um índice de eficiência com base na metodologia DEA sequencial VCR com orientação a produto. Construiu-se índices de competição. Usou-se o painel OLS com dados bienais de 2007 a 2015. Foram analisados três tipos de competição: horizontal (entre todas as escolas), privada (das escolas privadas) e vertical (entre escolas estaduais e municipais).
- Resultados: a competição horizontal influenciou fraca e positivamente a eficiência de escolas públicas associadas a redes de maior porte; a influência da competição privada foi fraca, mas positiva em redes maiores; e a da competição vertical, negativa em escolas municipais.
- Originalidade: Discute-se escolha e eficiência escolar em interface com a competição existente no Brasil em diferentes facetas, além de descrever e medir particularidades deste país quanto à competição e evidenciar limites à escolha.
- Contribuições teóricas e práticas: a teoria da escolha escolar adaptada ao Brasil considera as restrições à escolha, a competição vertical e a escolha dentro do território municipal. Reformas de ampliação da escolha, o fim da competição vertical e o fortalecimento das redes municipais são ações sugeridas para ampliar o efeito positivo da escolha e para melhorar os resultados educacionais no Brasil.
Do State capacity dimensions differently affect policy areas performance?
Authors: Cavalcante Pedro , Pereira Ana Karine 
Published: April 2022

Research objective: To analyze the determinants of governmental performance, assuming that policy sectors have different state capacities and produce heterogeneous effects on their performance.
Theoretical Framework: Grounded in the neo-Weberian bureaucracy and public governance debates, the inquiry tests if policy sectors (government core; infrastructure; productive development; security/citizenship, and social/environmental) present different state capacities and produce heterogeneous effects on outputs and outcomes.
Methodology: The research uses a survey applied to over three thousand civil servants of the Brazilian federal public administration to create composite variables of performance and state capacities dimensions, then descriptively compare these variables and run a multivariate regression to test the hypotheses.
Results: The paper confirms that the degree of state capacity development impacts the bureaucrats’ perception of performance and, secondly, these effects are quite diverse on the organizational outputs and outcomes. However, their variation among policy areas is not as expressive as expected. The findings reinforce recent studies that claim that governmental investment in state capacity became broader and more inclusive as it incorporated several agencies that do not belong to the classical “pocket of efficiency.”
Originality: Based on an original dataset, the research shows insights at advancing the study of state capacity, governance, and public sector performance. The comparative analyzes are unprecedented as it encompasses simultaneously crucial dimensions of the public service in Brazil, such as meritocracy, autonomy, relationship, skills, resources and, accountability.
Theoretical and Practical Contributions: In theoretical terms, the paper tests essential hypotheses concerning the federal government bureaucracy and performance, mostly restricted to the international literature. It also explores the policy sectors' heterogeneity and how it affects their performance, shedding light on the need for a more inclusive and comprehensive civil service and management policy.
Recognition of Detrital Carbonaceous Material in the Ryoke Metamorphic Belt by Using Raman Thermometry: Implications for Thermal Structure and Detrital Origin

Published: April 2022

Abstract
Raman spectroscopy of carbonaceous material (RSCM) thermometry is an effective method to determine the thermal structure of metasedimentary domains with high spatial resolution. The mean value of numerous measurements in a single sample is used for temperature estimation. A potential complicating factor is the presence of detrital carbonaceous material (CM) that can introduce bias in the results. Detrital CM generally shows a high degree of crystallinity making it difficult to discriminate detrital and metamorphic CM in high-grade metamorphic domains. Application of the RSCM thermometry to 100 metamudstone samples from the Hongusan area of the Ryoke metamorphic belt reveals multimodal degrees of crystallinity of CM in many samples indicating the common presence of detrital CM grains. Application of a new procedure to filter out the effects of detrital CM reveals a thermal structure that can be explained as the result of the overprinting of two distinct thermal regimes related to regional and subsequent contact metamorphism. The ability to recognize the presence of detrital CM and measure its crystallinity can be used to infer the metamorphic grade present in the hinterland from which the detrital material is derived. A combination of this information on metamorphic temperature with geochemical and radiometric age data reported in the literature indicates that the detrital CM was derived from basement rocks of the Korean Peninsula.

Abstract
Purpose: This study aimed to assess the longitudinal changes of choroidal thickness using enhanced depth imaging optical coherence tomography (EDI-OCT) during pregnancy and post-partum.Methods: The study included 23 eyes of 23 healthy pregnant women and 23 eyes of 23 healthy non-pregnant women. Choroidal thickness (CT) was measured manually with EDI-OCT at seven locations: the fovea, 500, 1000 and 1500 μm temporal (T) from the fovea and 500, 1000 and 1500 μm nasal (N) from the fovea. Measurements were obtained at each pregnancy trimester and 6 weeks post-partum and in the follicular phase of the menstrual cycle for the control group.Results: The mean subfoveal choroidal thickness was 410.2 ± 82.4 μm, 434.8 ± 79.6 μm, 433.5 ± 80.3 μm, and 395.0 ± 71.1 μm in the first, second and third trimesters and 6 weeks post-partum, respectively. In all seven measured locations, statistically significant changes were noted during pregnancy and post-partum in the choroidal thickness (p<0.001). Choroidal thickness increased from the first trimester to the second and third trimester, after which it decreased at post-partum. Choroidal thickness was greater in the pregnant group during pregnancy and post-partum compared to the control group (p<0.001).Conclusion: This study indicated significant change in choroidal thickness at seven locations measured with EDI-OCT throughout pregnancy and 6 weeks after delivery. We showed that 6 weeks after delivery, choroidal thickness remains significantly higher than non-pregnant subjects.

Abstract
Introduction: The COVID-19 pandemic has brought about important changes. On March 14, 2020, a strict home confinement was decreed in Spain. Children did not attend school and were not allowed to leave their homes. The aim of this study was to determine the emotional state of these children, as well as associated factors. Material and methods: A cross-sectional descriptive study was conducted using an online questionnaire sent by cell phone. This survey includes sociodemographic items and questions concerning the emotional impact of the lockdown. With the questions on emotions, two categories of emotional state were established with the variables fear, irritability, sadness and somatization: those who were less or more emotionally affected. A multivariate logistic model was used to estimate the associations between the variables. Results: A total of 3890 responses were obtained. The mean age of the children was 6.47 years (range 0 to 17). A score indicating poor emotional state was reported by 40.12%. The multivariate logistic model for poor emotional state was directly associated with having less appetite, sleep disturbances, and with parents’ beliefs that their child will have difficulties returning to normal life after lockdown. A better emotional state was associated with being an only child, access to outdoor spaces at home, having pets, and parents informing their children about the pandemic using creative explanations. Conclusions: During strict home confinement, a considerable emotional impact was observed in children as described by their parents. Specific elements were associated with a better or poorer emotional state.

Abstract
Background: Tumor DNA from tumor in situ fluid (TISF) provides a minimally invasive approach to repeatedly interrogated the glioma genome and provides an opportunity to monitor the dynamics of pressure-induced cloning for recurrence and treatment selectivity. Understanding the evolution of glioma will be of great help in clinical and scientific research of glioma. Currently, no study has explored the recurrence process of glioma.Methods: We performed high-depth generation gene sequencing in multiple regions of matched primary and recurrent tumors. Using 60 primary tumor tissues and their TISF, 26 of whom had tumor recurrence and 6 underwent 2 surgeries, we analyzed the heterogeneity of each period.Results：We measured considerable genomic variation in glioma patients at different times under the stress of first-line treatment. In gliomas dominated by genomic alleles with low frequency (VAF < 1%), radiographic residues had higher VAF (p = 0.016), and patients with postoperative recurrence also had higher VAF (p < 0.0001). Under the pressure of treatment, polyclonal mutations gradually increased with tumor evolution, and high-frequency dominant clones gradually appeared. Samples of relapsed TISF contained more abundant clonal mutations. Sequencing of relapsed tumor tissue and relapsed TISF samples showed high consistency in mutation detection and estimation of allele frequency (p < 0.0001, VAF correlation, R2 = 0.8737). Heterogeneity at different stages of the tumor was shown in patients who were continuously monitored. We determined that TISF may detect elevated Tumor DNA variant allele fraction prior to positive imaging findings and effectively identify patients with pseudoprogression.Conclusions: Continuous TISF-DNA analysis reveals the evolutionary structure of gliomas under first-line therapy and can be used to track postoperative residual disease and tumor recurrence. Most importantly, it could move glioma research forward.
Investigation of a toxic Microcystis sp. (Cyanobacteria) collected from Snow Lake (New Mexico, USA).
Authors: Shalygin Sergei , Holguin Omar 
Published: April 2022

Abstract
The toxin producing cyanobacterium Microcystis sp. was collected in the mid October 2020 from the shallow waters of Snow Lake (New Mexico, USA). This dominate species caused a visible bloom consisting of the pale green irregular macro colonies. Mass spectral analysis revealed the presence of 4 derivatives of microcystin in that bloom: MC-LR found in the water and biomass, MC-RR, -LY, -YR found in biomass only. Next-generation sequencing analysis of a collected biomass allowed the retrieval of two Microcystis sequences in the bloom, which may serve as molecular benchmarks for toxic Microcystis in the future monitoring studies. Light microscopy including shape of microscopic colonies provided evidence for the nomenclatural identification of the found morphotype as Microcystis flos-aquae (Wittrock) Kirchner. However, molecular sequencing and the current situation in cyanobacterial systematics prevented affiliation of our morphotype to Microcystis flos-aquae, justifying following name – Microcystis sp. Confocal microscopy determined the distribution of the cell content utilizing 3D stereo imaging. Emission spectra analysis identified the pigment composition and pigment distribution within the cells. SEM revealed 3D arrangement of the cells in the colonies, texture of the surface of the cells, F-layer and pili-like structures. Additionally, SEM/EDS analysis confirmed the F-layer using elemental composition analysis, which showed presence of sulfur in it – typical element for that structure. Through the use of AFM, we analyzed the texture of the cells surface and confirmed pili-like structures. As a summary, we detected toxin producing Microcystis spp. populations that were sequenced using Next-generation sequencing techniques. Obtained sequences may serve as phylogenetic benchmark for the toxic Microcystis populations during future investigations. Additionally, in depth pigment and ultrastructural analysis was performed on the toxigenic populations.
