The essay also chronicles Judge Weinstein’s approach to sentencing and commitment to procedural justice.
Perfect Pitch
Authors: Rosenberg Ruth E.
Published: March 2021

432 Hz music is a relatively recent internet-based phenomenon that has attracted listeners and musicians from all parts of the world. Increasingly connected via social media, listeners in this subculture do not necessarily share the same musical tastes or backgrounds. Rather, they have in common a belief that music tuned to the standard pitch of A-440 Hz is in some sense “out of tune” with nature or humanity. Alternatively, they prefer (and in some cases promote and advocate for) music that is tuned to a slightly lower, A-432 Hz standard. This preference is, for many, connected to beliefs that the A-432 Hz tuning reference can be physically, psychologically, and even spiritually beneficial. This article examines the promise of—and skepticism towards—the concept of “frequency” that is at the center of the 432 Hz phenomenon. It draws from research into some of the common historical, scientific, and conspiratorial claims made by 432 Hz advocates, as well as from qualitative data collected from dedicated 432 Hz listeners. After exploring the listening practices and media engagement of 432 Hz proponents, the article asks how the rise of 432 Hz music might relate to other recent and emerging forms of music consumption, the affective marketing of sound, and the management of personal sonic space.
Analysis of Studentâ€™s Difficulties in Solving Physics Problem: Impulse and Momentum Topics
Authors: Adianto Tri , Rusli Muhammad Aqil
Published: March 2021

Physics education essentially intends to cultivate studentâ€™s analytical and reasoning capabilities. However, this objective is hard to achieve because there are many students who facing difficulties in solving physics problems. This research was conducted to identify the types of studentâ€™s difficulties in solving momentum and impulse problems, along with the factors causing it. This research was conducted using a descriptive qualitative approach to 66 students of Senior High School 2 Makassar who had studied momentum and impulse topics. The data collection process was carried out using test and interviews. Based on the results, it can be identified that there are two types of studentâ€™s difficulties in solving momentum and impulse problems. The first type was physical difficulties which consisted of studentâ€™s difficulty in understanding the questions (26%) and studentâ€™s difficulty in determining the useable equations (25%). Then, the second type was mathematical difficulties which consisted of studentâ€™s difficulty in substituting the data to the equation (63%) and studentâ€™s difficulty in performing mathematical operations (76%). Based on interviews and analysis, it can be concluded that these difficulties was commonly faced by students while solving physics problems, including in momentum and impulse topic. Futhermore, the difiiculties were caused by several factors, namely: 1) the lack of studentâ€™s understanding about physics concepts, 2) the weakness of studentâ€™s mathematical skills, 3) the lack of physics learning process which is not honing studentâ€™s problem-solving skills and  4) the lack of studentâ€™s motivation on developing their problems solving skills in physics subjects. Thus, researchers recommend to all physics teachers in Indonesia to immediately develop or implement learning strategies or methods which are considered capable of overcome all studentâ€™s difficulties that have been found.
Science Process Skills in Science Education of Developed and Developing Countries: Literature Review
Authors: Mushani Mercy
Published: March 2021

The purpose of this literature review is to analyze and evaluate the research studies conducted on science process skills (SPS) in science education in the context of developed and developing countries. A follow-up to this study will investigate teacher facilitation of SPS development at Primary School level in Zambia. The method carried out in this study is a literature review. It involved analyzing and synthesizing some research work already conducted globally, considering the educational significance of SPS. The search was limited to peer-reviewed journal articles written in English and whose full papers were available on the databases. Additionally, the articles were published between 1987 and 2018 because SPS's teaching and learning has been prevalent in research since the early 1980s. In total, 198 articles were found as a result of the initial search. The researcher screened abstracts of these articles to judge their relevance, and from this screening process of abstracts, 40 papers have been included for review. Reviewed study trends on SPS development conducted from developed and developing countries focusing on three vantage points: science curriculum, teacher education and the 21st Century Learning. Based on the findings, more research studies on SPS in science education are carried out in developed countries than developing ones. The review findings indicate uneven inclusion of SPS in the science curriculum documents and the curriculum implementation at all science education levels. Lastly, results display few studies on SPS education regarding 21st Century Learning conducted in developed and developing countries. Concerned education bodies must take appropriate and reasonable exploits on teacher training of SPS education and the balanced inclusion of SPS in the science curriculum and its implementation into consideration. SPS still champions the development of other skills individuals are supposed to possess in this 21st-century era. Hence, SPS education in science education remains a need for both developed and developing countries.

Published: March 2021

Thyroid cancer is a common endocrine neoplasm. Despite its good prognosis, it can lead to significant morbidity and mortality due to metastasis and recurrence. However, the factors involved in metastasis are not well studied. Therefore, we selected matrix metalloproteinases 2 (MMP2) and determined whether it has any role in thyroid cancer. We sequenced the exons of MMP2 in 211 samples including 16 multi-nodular goiters and 195 differentiated thyroid cancers. We identified four non-synonymous single nucleotide polymorphisms (SNPs) of the MMP2 gene in 3.06% (6/195) thyroid cancers. Of the four tumors harboring MMP2 SNPs, three (75%) concomitantly had BRAFV600E. Hence, we speculated that the MMP2 SNPs may cooperate with BRAFV600E in promoting tumor aggressiveness. Overexpression of two MMP2 SNPs (P38L and T458I) exhibited markedly enhanced gelatinase activity with an intact dimerization and induced strong cortactin foci formation in HEK293T cells. Stable expression of the two MMP2 SNPs in BRAFV600E positive BCPAP cells dramatically enhanced cell proliferation, colony formation, and focus formation. Analysis of the morphology of MMP2 SNP bearing BCPAPV600E cells exhibited highly invasive phenotypes characterized by a high rate of wound healing and enhanced cell invasion compared with parental BCPAPV600E cells bearing vector. We also determined that BCPAPV600E cells stably transfected with MMP2 SNPs were highly sensitive to the treatment of BRAF inhibitor, PLX4720. Our study demonstrates that MMP2 SNPs could cooperate with BRAFV600E to promote oncogenicity, migration, and invasiveness of PTC cells. These results suggest that a subset of papillary thyroid cancer with this genetic makeup may benefit from BRAF-mediated therapeutic interventions.

Published: March 2021

It is uncertain whether serum TSH concentration is an independent risk factor for the malignancy of pediatric thyroid nodules. We sought the association of serum TSH concentration with the malignancy of pediatric thyroid nodules and with the characteristics of pediatric thyroid cancer. A total of 219 pediatric thyroid nodule patients were collected retrospectively for 5 consecutive years. The medical records collected included sex, age, serum TSH concentration, thyroid autoantibody status, thyroid ultra-sonography parameters, histological type, and pathological TNM stages. The serum TSH concentrations were compared between benign and malignant nodules or corresponding subgroups. Binary logistic regression analysis was used to evaluate the correlation of TSH concentration with the malignancy of thyroid nodules and with the characteristics of pediatric thyroid cancer. There was no significant difference in TSH concentration between benign nodule and thyroid cancer in total subjects and various subgroups. The serum TSH level was not correlated with the malignancy of thyroid nodules in univariate analysis, but negatively correlated with the malignancy of thyroid nodules (odds ratio = 0.856, P  = 0.013) after adjusting for the patients’ sex, age, thyroid autoantibody status, and nodule size. The serum TSH level was not correlated with the tumor characteristics in pediatric thyroid cancer patients. In conclusion, the serum TSH concentration seems not to be a carcinogenic factor in pediatric thyroid nodule patients, nor to be an independent risk factor for characteristics of pre-existing pediatric thyroid cancers.

Published: March 2021

Based on experimental data, the inhibition of the MAPkinase pathway in patients with radioiodine-refractory thyroid cancer was capable of inducing a redifferentiation. Preliminary data obtained in a small series of patients were encouraging and this strategy might become an alternative treatment in those patients with a druggable mutation that induces a stimulation of the MAP kinase pathway. This is an active field of research to answer many still unresolved questions.

Heterospecific embryo transfer of an endangered species has been carried out using recipients from related domestic females. Aggregation of an embryo from an endangered species with a tetraploid embryo from the species to be transferred could improve the development of pregnancy to term. The main objective of the present study was to analyze embryo aggregation in domestic cat model using hybrid embryos. For this purpose, we compared in vitro development of synchronic (Sync) or asynchronic (Async) and asynchronic with a tetraploid (Async4n) aggregation of domestic cat IVF embryos. Furthermore, aggregated blastocyst quality was analyzed by evaluation of the total cell number, cell allocation by mitotrackers staining of embryonic cells, expression of Oct4, Nanog, Sox2, Cdx2 genes, number of OCT4+ nuclei, and presence of DNA fragmentation. Additionally, the developmental rates of Async4n aggregation of domestic cat with Leopardus geoffroyi hybrid (hLg) embryos were evaluated. Async aggregation increased blastocyst cell number and the number of OCT4+ nuclei as compared to non-aggregated diploid (2n) and tetraploid (4n) embryos. Moreover, blastocysts produced by Async4n aggregation showed reduced rates of fragmented DNA. No differences were found in the expression of the pluripotent genes, with exception of the Cdx2 expression, which was higher in 4n and aggregated embryos as compared to the control group. Interestingly, hybrids embryos derived by Async4n aggregation with domestic cat embryos had similar rates of blastocysts development as the control. Altogether, the findings support the use of two-cell-fused embryos to generate tetraploid blastomeres and demonstrate that Async4n aggregation generates good quality embryos.

Published: March 2021

Volcanic cinder, also known as scoria, is an extrusive igneous rock that forms when gas-rich magmas of basaltic or andesitic composition cool quickly. It is typically dark in color, ranging from black to red depending on its chemical composition. Sometimes fresh cinder samples show a variety of shiny metallic colors on its surface ranging from blue to gold to silver. The origin of these colors has remained unknown up to now. Cinder samples from an eruptive event occurred in October 2005 have been collected in the surroundings of the Sierra Negra volcano in the Galápagos Islands. The samples’ crystallographic structure, chemical composition, and surface morphology have been analyzed using X-Ray diffractometry (XRD), energy dispersive X-Ray spectroscopy (EDS) and a field gun emission scanning electron microscopy (SEM), respectively. Based on an extensive physical and chemical analysis, we were able to demonstrate that these colors are due to a light interference phenomenon. These results have a great potential to be used for a wide variety of purposes such as determining the temperature and composition of magma and evaluating volcanic samples for planetary studies.

Published: March 2021

This paper deals with an inter-annotator agreement test involving the identification of the information unit of Topic as defined within the framework of the Language into Act Theory (L-AcT). Fleiss’s kappa statistic was used to measure the agreement among the four annotators who took part in the test. The data used was sampled from C-ORAL-BRASIL II, a spontaneous speech corpus of Brazilian Portuguese. The paper begins by outlining of the theoretical underpinnings of L-AcT, dedicating special attention to aspects directly related to the notion of Topic. Section 2 presents the pilot test and discusses methodological and theoretical issues that were relevant for the design of the protocol that was eventually used in the actual test. Sections 3 and 4 deal with the test, its protocol and results (the kappa coefficient for the general agreement was 0.79, which by usual standards represents a substantial agreement). Section 5 first provides a brief review of a few studies conducted according to other frameworks which have dealt with inter-rater agreement on the annotation of information structure categories. Finally, the errors observed in the test are analyzed qualitatively.

Authors: Cao Yongqiang , Jing Yande , Hao Hao , Wang Xuan
Published: March 2021

Effects of aging after pyrolysis were tested relative to the physicochemical characteristics of peanut straw biochar. Biochar was prepared at pyrolysis temperatures of 350 °C, 500 °C, and 650 °C; then, it was freeze-thawed and dry-wet aged. The physicochemical characteristics of the fresh and aged biochar were analyzed. The results showed that the pyrolysis temperature, ambient temperature, and humidity affected the physicochemical characteristics of the biochar. With the increase of pyrolysis temperature, the yield and surface acidic functional groups of the fresh biochar decreased, whereas the ash content, C content, pH, specific surface area, and mesoporous volume of the fresh biochar increased. The aging treatment increased the acidic functional groups content in the biochar and reduced the aromatic functional groups content, which decreased the pH value of the biochar. The aging treatment increased the specific surface area and pore volume of the biochar, and the effect of freeze-thaw aging was greater than that of dry-wet aging. The aging treatment also destroyed the complete shape of the fresh biochar, and reduced its stability. After the aging treatment, the C content of the biochar decreased, whereas the O content increased, due to oxidation of the biochar.

The influence of copper and its nanoparticles was studied relative to growth and ultrastructure of Aspergillus niger. Laccase production by A. niger using corn cobs as substrate at different concentrations of CuSO4 and copper nanoparticles (CuNPs) is reported. Fungus growth was induced at 100 ppm of CuNPs and CuSO4, while at 300 ppm, the growth inhibition was 65.6% and 86.9%, respectively. Fungus sporulation was reduced to 30.4% and 47.6% at 300 ppm of CuNPs and CuSO4, respectively, compared to the control (100%). Transmission electron microscopy revealed that CuSO4 and CuNPs treatments encouraged the deformed appearance of the fungus at 200 ppm and 300 ppm, particularly CuNPs. The CuNPs and CuSO4 induced laccase production at 1.67 U/mL and 1.51 U/mL at optimum concentrations 0.15 mM and 0.25 mM, respectively. The optimum concentrations of CuNPs and CuSO4 led to reduced incubation periods of 12 d and 14 d, respectively, required to produce the highest amount of laccase (1.66 U/mL and 1.53 U/mL), while without treatments, the incubation period increased to 16 d required for the highest amount of laccase production (1.36 U/mL). Induction of laccase production at acidic pH and at 30 °C was recorded with the addition of CuSO4 and CuNPs, while its effects were slight at pH above 6.

Published: March 2021

Black liquor alkaline lignin and magnesium lignosulfonate were liquefied at 320 oC. The antioxidant abilities of the liquefaction products were compared with the raw materials. Results showed that the total phenol content and unit antioxidant power of both alkaline lignin liquefaction products (ALLP) and magnesium lignosulfonate liquefaction products (MLLP) were improved, and ALLP had a larger increase than MLLP. The influence of reaction time and temperature on oil yield, total phenol content, and antioxidant power of ALLP was evaluated. The total phenol content was found to have certain relationships with the antioxidant abilities. These results explore a new approach for further studies and applications of liquid antioxidant from lignins.

Published: March 2021

Located in the Trapani Mountains of North-West Sicily, the hilltop site of Pizzo Monaco hasformed the focus of systematic excavation and an innovative, integrated study of the totalceramic assemblage, as part of the MEMOLA FP7 project. The date, provenance and productiontechnology of the varied types of pottery are investigated by macroscopic, morphological anddecorative analysis, in combination with petrography and scanning electron microscopy in orderto assess social, technological and economic ties of this rural site and its environs with the earlyIslamic capital of Sicily at Palermo, the wider island and North Africa. Local production of cookingvessels is compared with glazed and plain storage pottery, serving and consumption vesselsfrom Palermo, in a region where the new relationship between coastal centre and nearby mountaineconomies was being forged. Correlation of the properties of the pottery assemblage withthe unusual architecture suggests the storage of a repeated ceramic set, perhaps on a householdbasis, in a site which may be a fortified storage facility, rather than sustaining more permanentoccupation. The typological study provides new information on the range of ceramics circulatingin Sicily during the mid-11th century CE, revealing the full spectrum of ceramics consumedat this time. This approach contrasts with work that privileges a view of simple transmissionof glazing technologies across the Islamic Mediterranean. Indeed a comparison of productionsequences in the crafting of similar glazed bowls at Palermo demonstrates the co-existence ofdifferent communities of practice and cautions against over-simplified reconstructions of thetransmission of glazing technologies in the early medieval Mediterranean. The range of potteryavailable from a variety of sources highlights the consumption choices made by these communitiesin the medieval period.

Published: March 2021

Reseda is an understudied genus regarding germination ecology. We studied the germination response of eight perennial Reseda species to fire related cues by performing a germination experiment including two aqueous smoke treatments (at 1:5 and 1:20 concentrations), one heat shock (100 °C for 5 min.) treatment, and two corresponding controls. Smoke slightly decreased germination percentage in R. aucheri ssp. rotundifolia and R. minoica, and the reduction in R. luteola was statistically significant (P < 0.01). In contrary, smoke promoted germination in R. coodei, R. globulosa, and R. orientalis slightly, and markedly in R. anatolica (from 3 to 11%; P = 0.055). Heat shock treatment did not affect the germination in three of four species tested, but significantly increased germination percentage in R. luteola in comparison to the control (P = 0.046). Consequently, there was no consistent germination response to smoke or heat shock in Reseda species studied. This study is the most comprehensive study tested fire-related germination of several Reseda species and provides the first germination results on seven Reseda species. Further studies that include more species and treatments would show a more completed figure for fire-related germination patterns in the genus Reseda.

Published: March 2021

Abstract Despite being a minor part of the atmosphere's composition, the so-called greenhouse gases play a crucial role in their thermodynamics. Over the past 200 years, however, human activities have significantly altered the global carbon cycle. Thus, in the current context of global warming, quantifying, with increasingly reliable values, greenhouse gas emissions and the global carbon cycle has become one of scientists’ priorities. This study aims to develop a system for acquisition and wireless transmission of carbon dioxide data from the C-Sense, a sensor manufactured by Turner Designs. As result, a reliable, compact and versatile circuit has been developed that acts as an embedded system for monitoring CO2 concentration and partial pressure, as well as two temperature variables. Regarding the transmission of data via radio frequency, its data transmission has a range of 470 m without loss. A Python script has been implemented that stores data and generates real-time graphs for system monitoring.

Published: March 2021

ABSTRACT Objective: The aim of this work is to provide evidence for the relationship between suspicion and diagnosis of cases of child abuse and fractures, since, in national literature, studies are still scarce on the subject. Methods: Retrospective study involving electronic medical records of a public reference hospital, in a city of the state of São Paulo, in a 8-year period (2010 to 2018). Cases involving children up to 12 years of age were selected when notified as abuse and presenting fractures; data were statistically analyzed. Results: Among 83 cases of abuse, 19 patients (20.5%) had 23 different fractures. The victims were mainly boys (68.42%) with a mean age of 5 years old, who suffered physical aggression (79%). The majority had no identified aggressor (52%) and 21% were related to the mother. The fracture patterns found involved, mostly, skull fractures (43.48%) and diaphysary fractures (34.78%). Seven patients (30.43%) had other associated lesions and four patients died (21%). Conclusion: Despite the number of cases, it was possible to identify relevant characteristics and patterns. These data indicate that the diagnosis is underestimated and show small epidemiological differences compared with international literature. Level of Evidence II, Retrospective study.

ABSTRACT Objectives: To describe the clinical and radiographic results of patients with traumatic recurrent anterior shoulder dislocation treated with the Bristow-Latarjet procedure. Methods: Retrospective case series including 44 patients (45 shoulders) who underwent the Bristow-Latarjet procedure. The graft was fixed “standing” in 84% of the shoulders, and “lying” in 16%. Results: The follow-up was 19.25 ± 10.24 months. We obtained 96% of good results, with 2 recurrences presented as subluxation. Graft healing occurred in 62% of cases. The graft was positioned below the glenoid equator in 84% of the cases, and less than 10 mm from its edge in 98%. The external rotation had a limitation of 20.7º ± 15.9º, while the internal rotation was limited in 4.0º ± 9.6º. The limitation of rotation and the position of the graft (“standing” or “lying”) did not correlate with graft healing (p>0.05). Bicortical fixation was positively correlated with healing (p <0.001). Conclusion: The Bristow-Latarjet technique is indicated for the treatment of recurrent anterior dislocations and subluxations of the shoulder. It is a safe treatment method, which can be used in people with intense physical activity. Limiting shoulder mobility does not prevent patients from returning to their usual occupations.

RESUMO Testaram-se as hipóteses de que, assim como em reservatórios de grande áreas de superfície, volumes e vazão, em reservatórios pequenos também ocorrem a diluição gradual e contínua da riqueza, da diversidade e abundância de microcrustáceos (Cladocera e Copepoda) a jusante dos mesmos, sem a recomposição da riqueza a jusante pela falta de rios tributários, lagoas marginais e até pelo pequeno porte do riacho, sem condições para o desenvolvimento do potamoplâncton próprio do sistema. Foram estudados dois pequenos reservatórios e seus trechos a jusante, com coletas diárias a cada seis horas em oito pontos de amostragem, sendo dois lênticos e seis lóticos a jusante de cada. Foram encontradas 19 espécies (11 de Cladocera e oito de Copepoda), com destaque para o maior número de espécies litorâneas do que pelágicas, e a maior abundância de cladóceros litorâneos nos pontos a jusante dos reservatórios. Não houve diferença entre os horários, indicando que a escala espacial foi mais importante que a temporal. Houve maiores valores dos atributos ecológicos nos ambientes lênticos, porém houve aumentos significativos de riqueza e diversidade nos últimos pontos dos trechos de riacho, enquanto que a abundância diminuiu gradativamente a jusante. Não foram encontradas correlações significativas da abundância dos táxons com nenhuma variável limnológica (temperatura, pH, oxigênio dissolvido, turbidez, sólidos totais dissolvidos e transparência), indicando pouco ou nenhum efeito destas variáveis. A análise de cluster com distância euclidiana separou dois grandes grupos, o primeiro formado pelo trecho a jusante do primeiro reservatório e o segundo com os demais pontos. Além da presença dos táxons litorâneos vindos dos reservatórios, houve incremento de táxons litorâneos residentes nos riachos. Pode-se concluir que houve uma diluição da abundância das espécies a jusante dos riachos, mas a riqueza e a diversidade permaneceram estáveis devido à contribuição de táxons litorâneos.

Raça e antiescravismo no Caribe espanhol: o ativismo de Antonio Maceo e Ramón Emeterio Betances
Authors: Mata Iacy Maia
Published: March 2021

RESUMO É objetivo deste artigo discutir o antiescravismo no Caribe espanhol através da atuação do cubano Antonio Maceo (1845-1896) e do porto-riquenho Ramón Emeterio Betances (1827-1898). A pesquisa busca reconstituir o ambiente político do Caribe espanhol no período de 1863 a 1881, no contexto de guerras de independência, e o protagonismo específico de homens negros que reivindicaram solidariedade racial na luta pela abolição da escravidão. A partir de algumas correspondências e documentos produzidos por Maceo e Betances (ou com sua participação), e da documentação gerada pelas autoridades coloniais, serão discutidas a construção de redes e conexões transnacionais, com base racial, pelos ativistas que lutavam contra a escravidão e as discriminações e por direitos políticos integrais. Chamo especial atenção para a interlocução com os haitianos e para a insistente referência ao Haiti no vocabulário político daqueles ativistas.

RESUMO Amparado no uso de acervos repressivos, o artigo explora representações anticomunistas difundidas pela comunidade de segurança e informações, que associaram o uso de drogas a uma estratégia do movimento comunista internacional para corromper a juventude durante a ditadura. Essa acusação se vinculava a uma tradição anticomunista conspiracionista atualizada pela Guerra Fria e pelos protestos juvenis nos anos 1960/1970, impactada pela modalidade repressiva transnacional da guerra às drogas desenvolvida pelos Estados Unidos. Esses elementos convergiram com argumentos do probicionismo que tomavam a droga como o fantasma do mal vinculado à destruição da família e à devassidão moral-sexual. Por isso, alguns documentos sobre a toxicomania comunista no Brasil modelaram essa percepção. Em paralelo ao pânico anticomunista, a repetição do argumento não esteve fundamentada em evidências. Essas frações inflacionaram o perigo vermelho, instrumentalizando-o para demarcar posições políticas ao longo da ditadura militar.
Tráfico interprovincial e alforria em grandes propriedades do termo de Monte Alto, Século XIX
Authors: Miranda Rosângela Figueiredo
Published: March 2021

RESUMO O artigo analisa articulações entre senhores e escravos em grandes propriedades do termo de Monte Alto, no Alto Sertão da Bahia, durante o século XIX. As terras vastas e propícias ao desenvolvimento da agricultura e da pecuária permitiram atividades diversificadas. O fim do tráfico Atlântico (1850) e o intenso tráfico interprovincial na região, a partir de 1840, marcaram a vida de muitos cativos, diante da ameaça de venda ao Sudeste do país, dificultando o processo de alforria. Propriedades contaram com escravaria numerosa e economia diversificada, permitindo aos cativos tecer com seus senhores possibilidades de arranjos e negociações de manumissão. Atrelado à História Social da Escravidão, este estudo centra-se no método da ligação nominativa em inventários, livros de notas e correspondências. Um banco de dados permitiu-nos analisar o perfil desses diferentes sujeitos sociais e os graus de articulações estabelecidos entre eles.
A “biblioteca do impossível”: levantamento da produção editorial do DPDC/DNP
Authors: Fraga André Barbosa
Published: March 2021

RESUMO Este artigo analisa a experiência inicial de produção editorial estatal do governo Vargas (1930-1945). O foco está voltado para a atuação do Departamento de Propaganda e Difusão Cultural (DPDC)/Departamento Nacional de Propaganda (DNP), primeiro órgão de publicidade política da década de 1930 a investir em publicações. O objetivo principal é fazer um levantamento minucioso, nos acervos de arquivos e bibliotecas, do conjunto de folhetos, livros e revistas editado especificamente pelo DPDC/DNP, algo não realizado por trabalhos anteriores. Como resultado, identificamos 88 títulos distintos, o que representa, aproximadamente, 81% de tudo o que esse departamento produziu.
A construção do poder em Angola nos romances de Pepetela: os novos ricos e a apropriação do Estado no pós-independência
Authors: Machado Carolina Bezerra
Published: March 2021

RESUMO No artigo, analiso as relações de poder construídas entre o Estado e a sociedade em Angola após a independência do país em 1975, a partir de suas ambivalências e acomodações de interesses. Defendo que houve a construção de uma estrutura política em que o Estado/MPLA passou a ser o principal meio para a distribuição de benefícios e privilégios, contribuindo para o fortalecimento de uma estrutura autoritária e patrimonialista ao longo dos anos. Ao destacarem um cenário de autoritarismo, clientelismo e patrimonialismo, os romances de Pepetela e a construção de seus personagens dialogam com uma narrativa crítica acerca do projeto político adotado pelo Estado angolano.

ABSTRACT Objective to identify the power devices used by nurses to fight domestic violence against women from the perspective of parrhesia. Method qualitative study addressing 20 nursts from 13 Primary Heath Care units located in Rio Grande, South of Brazil. Interviews were held from April to June 2018, and data were treated using NVIVO 11 under the light of the Discursive Textual Analysis and Foucault's philosophical framework. Result two categories emerged from the analysis: (1) knowledge devices and (2) administrative/institutional devices. The first refers to the nurses’ actions, such as sharing information concerning domestic violence against women and the second concerns the health units’ actions to fight violence and referrals to other sectors focused on providing care to women experiencing domestic violence. Conclusion nurses use power devices to support women so they can transform their lives. Nursing can promote social transformations as it is engaged with actions intended to promote health.

ABSTRACT: Objective: To analyze changes in the lifestyles of Brazilian adolescents during the COVID-19 pandemic. Methods: Cross-sectional study carried out with adolescents who participated in the survey “ConVid Adolescentes – Pesquisa de Comportamentos”. The indicators related to lifestyles before and during the COVID-19 pandemic were evaluated: consumption of healthy and unhealthy foods, physical activity and sedentary behavior, smoking and consumption of alcohol. Prevalence and 95% confidence intervals were calculated for the total population and according to sex and age group. Results: A total of 9,470 adolescents participated in the study. During the period of social distancing, there was an increase in the prevalence of vegetables consumption (from 27.34 to 30.5%), frozen foods (from 13.26 to 17.3%), chocolates and sweets (from 48.58 to 52.51%), and time in front of screens (from 44.57 to 70.15%). On the other hand, there was a decrease in the practice of physical activity (from 28.70 to 15.74%) and in the consumption of alcohol (from 17.72 to 12.77%). Differences were observed according to sex and age group. Conclusion: The results show changes in the lifestyle of adolescents and an increase in health risk behaviors.

Resumo O artigo teve como objetivo investigar de que modo os municípios brasileiros desenvolveram medidas para enfrentar a pandemia de Covid-19. Para isso, foi conduzido um estudo com dados da Confederação Nacional dos Municípios, coletados no segundo semestre de 2020. Os resultados apontaram que houve, inicialmente, a adoção de medidas como a implementação de barreiras sanitárias, isolamento social e promoção do uso de máscara; contudo, a maioria dos municípios flexibilizou essas ações ao longo do tempo. Além disso, observou-se que os entes municipais desenvolveram ações de resposta à pandemia de forma heterogênea e descoordenada. Concluiu-se que esse fenômeno se deve ao fato de que o governo federal e os estados da federação desenvolveram precários mecanismos de incentivo à cooperação interfederativa e pouco estimularam a coordenação de atividades no território brasileiro.

ABSTRACT Purpose: to validate indicators and parameters to construct an assessment instrument for the Hearing Conservation Program. Methods: methodological research to validate the content and layout of indicators to assess the Hearing Conservation Program, using the Delphi method, as well as the semantic validation of an assessment instrument for the program, in compliance with the procedures used by the European group DISABKIDS. A total of 20 speech-language-hearing therapists participated in the study, answering validation questionnaires. The answers were tabulated and analyzed considering descriptive statistical data, establishing the item content validity index, the scale content validity index, the percentage of absolute agreement, and the content analysis. Results: of the 64 items submitted for validation, two were not considered appropriate. The set of items was considered representative. The validated indicators and parameters provided the means to construct an assessment instrument of the degree of implementation of the Hearing Conservation Program, which proved to be semantically valid. Conclusion: the indicators were validated to meet and represent the functions of quality, control, and follow-up of the Hearing Conservation Program, aiding administrators to carry out their responsibilities and making it possible to construct evaluative instruments.

Published: March 2021

ABSTRACT Objective: The aim of this study was to evaluate the thickness of the zygomatic-maxillary cortical bone using computed tomography in different skeletal patterns. Methods: A total of 54 patients of both sexes, divided into three groups according to the vertical skeletal pattern, were evaluated for cortical bone thickness of the anterior slope of the zygomatic process of the maxilla, using cone beam computed tomography. Measurements were made at 2mm, 4mm, 6mm, 8mm and 10mm above from first molar mesial root apex. Vertical skeletal pattern was determined by Frankfurt mandibular angle (FMA). Results: The hyperdivergent pattern had the lowest cortical thickness value, nevertheless, no patient in the hyperdivergent group presented cortical thickness exceeding 2mm, and no patient in the hypodivergent group presented cortical thickness less than 1mm. However, the correlation between cortical thickness and mandibular plane angle was weak and not significant. Conclusion: Although higher prevalence of thick cortical was observed in the hypodivergent patients, and thin cortical groups in the hyperdivergent group, the vertical skeletal pattern could not be used as determinant of the zygomatic-maxillary cortical thickness.

Published: March 2021

Abstract Although many studies have emphasized the benefits of the integration of Building Information Modeling (BIM), there is no consensus on the information workflow among main processes used in construction, particularly in small- and medium-size enterprises (SMEs). Therefore, this work proposes an information workflow that integrates 3D BIM modeling, cost estimating, scheduling, and monitoring processes in SMEs (ICSM Information Workflow). This research adopts the design science research approach, which includes (a) a literature review and a study of the information workflow among the processes, (b) a proposal of an information workflow based on certain assumptions for integration, (c) a participatory process for testing and adapting the proposed workflow, and (d) an evaluation of the proposed information workflow. The results indicate the participatory and cyclical processes that were proposed to define the work packages using a standard WBS and a database for information integration were the key for integrating people, technologies, and processes. The main contributions of this study are the proposal of an information workflow that integrates cost estimating, scheduling, and monitoring with BIM in SMEs, and the lessons learned based on the pilot test and evaluation of the ICSM Information Workflow in one of the two projects studied.
