Authors: Alves Roberto Cavalleiro de Macedo , Pereira Alice Theresinha Cybis
Published: July 2023

O avanço da Tecnologia da Informação e Comunicação (TIC) nas mais variadas áreas do conhecimento, fez surgir no campo da arquitetura, engenharia e construção (AEC), o BIM (Building Information Modeling), ou, Modelagem da Informação da Construção. O processo BIM de projeto tem como premissa a colaboração contínua de todas as disciplinas no desenvolvimento do projeto. Nos sistemas colaborativos a infraestrutura que dá suporte à colaboração é realizada através da interação entre atividades de comunicação, coordenação e cooperação (Modelo de Colaboração 3C). Este artigo tem por objetivo apresentar o modelo BIM3C que busca orientar o fluxo colaborativo em processos BIM de projeto. Através de entrevistas com profissionais de AEC que utilizam BIM e a correlação destes resultados com a teoria do projeto colaborativo foi possível o desenvolvimento de um modelo específico para colaboração em BIM que abrange as 3 camadas que permeiam a sua implantação: pessoas, processos e tecnologias.Palavras-chave: BIM, projeto colaborativo, colaboração.

Published: July 2023

As cidades brasileiras têm seu processo de urbanização a partir do século XX com a ocupação do território nacional, a consolidação das fronteiras e a inversão populacional do campo para a cidade. Os fluxos de informação e de matéria, devido a industrialização e o grande crescimento econômico, ocasionaram complicações no meio urbano, principalmente nas cidades médias e nas regiões agrícolas e agroindustriais ativas, como o oeste catarinense, compostas basicamente por pequenos municípios. As cidades com agroindústria como Chapecó e Abelardo Luz se destacam por sua importância para a economia regional, visto que vinculado a cada indústria tem-se muitas propriedades rurais com a produção da matéria prima. Neste contexto de fluxos e dependências se observa que as micro e macro relações impactam na morfologia e consequentemente na paisagem destes núcleos urbanos. Contudo, este estudo objetiva analisar comparativamente as características socioespaciais registradas na paisagem e as contradições que intermediam a relação sociedade/território.Palavras-chave: morfologia, paisagem, Abelardo Luz, Chapecó.
Legacies Matter: Exploring Social Acceptance of Pumped Storage Hydro in Michigan’s Upper Peninsula
Authors: Tiwari Shardul , Schelly Chelsea , Sidortsov Roman
Published: July 2023

Using electrical energy for an increasingly wide range of energy services (including lighting, heating, cooling, food storage, communications, and transport) requires grappling with the impacts of these systems on ecologies and societies. Renewable energy can provide less ecologically damaging electrical energy, but intermittency—the fact that solar requires the sun to shine and wind requires a breeze for energy to be produced—means having to create a way to store electrical energy to balance production and demand effectively. Underground storage hydro energy systems offer one way to achieve this, and one innovative approach involves repurposing abandoned underground mine shafts for pumped underground storage hydro (PUSH) systems. In this article, we present an initial foray into the social acceptance (SA) of the potential development of a PUSH facility. The article looks at the case of SA of a PUSH facility in a post-mining community in the Upper Peninsula of Michigan through its three pillars: community acceptance, sociopolitical acceptance, and market acceptance. This case study reveals that community input into design considerations and economic participation are the primary drivers and may be required to achieve community acceptance. The study provides insights regarding the importance of engaging the community in discussions while planning for large energy infrastructure to spur renewable energy transition. The case study will further engage the audience in understanding the SA of energy storage systems when developed in brownfield sites (abandoned mines) instead of greenfield sites.

The full potential linearized augmented plane wave (FP-LAPW) approach based on the density functional theory (DFT) is employed to know the effect of Co doping on the electronic, optical, and magnetic characteristics of BaTi1-xCoxO3 at x= 8.33%, 16.66%, 25%, and 50%. The computed spin-polarized electronic band structure (BS) and the density of states (DOS) elucidate that the BaTi1-xCoxO3 compound has a ferromagnetic semiconductor behavior at all doping concentrations. The results indicate that the magnetic moment in BaTi1-xCoxO3 is found due to the p-d hybrid orbitals of Co. Moreover, the optical features of the Co-doped BTO compound are evaluated by analyzing the refractive index, reflectivity, absorption coefficient, optical conductivity, and dielectric constant under different concentrations. The outcomes revealed that the BaTi1-xCoxO3 compound is a good candidate for spintronics and optoelectronic applications.

In this work, we have developed thin layers of CuO by method of pyrolysis spray. The samples developed are obtained from the use of copper chloride precursor CuCl2 with molarity of 0.1 mol/l and a spray number that varies between 25 to 150 spray with a step of 25 spray to see the effect of this parameter on the structural, optical and electrical properties of our material. The structural characterization of the obtained thin layers was done by X-ray diffraction (XDR) and spectroscopy Raman. The optical characterization was done by UV visible spectroscopy and electrical characterization by four points. The XDR has confirmed the crystalline state of our thin layers and the formation of the CuO with a preferential direction according to the plan (002). The Raman spectroscopy allowed us to confirm the presence of a thin layer based on the CuO. The lattice parameters remain mainly constant. The spectra UV visible of films has given a transmission varies between 80% and 40% in visible. The optical gap determined varies between 1.75 eV and 1.2 eV. Electrical characterization shows that the resistivity varied between 3.21KΩ.cm and 1.7KΩ.cm depending on number of spray for ethanol gas sensing applications.

Authors: Ma'rifah Dina , Soenhadji Iman Murtono
Published: July 2023

The quality of education is one of the measurements in determining the quality of a nation because education can produce qualified human resources. The result of the PISA showed that the quality of education in Indonesia, from students’ literacy level, was in the low position because the quality of education was uneven, in this case, the performance of teachers. Teacher performance would affect the quality of students’ learning process. In addition, to create an effective organization, the attitude of teachers' professional performance needed to be supported by a voluntary attitude, namely Organizational Citizenship Behavior (OCB). This study aimed to analyze the direct and indirect effects of remuneration on teacher performance with OCB as mediation. This was associative research with the quantitative approach which aimed to find relations that explain measurable causes and facts, also show variable relations, and perform analysis. The subjects in this study were public and private high school teachers in Depok. The number of respondents was 250 teachers. A questionnaire was used as a data collection method. The analysis used was multiple linear regression and path analysis. Based on the results of the study, there was a joint influence between the variables of remuneration, job satisfaction, and OCB on teacher performance. The dominant variable that affected OCB and teacher performance was job satisfaction.

Published: July 2023

This study aims to measure the level of effectiveness of the Dynamic Archival Information System (SIKD) in managing archives. The data analysis technique used in this research is descriptive qualitative with simple tabulation calculations. Data collection techniques used interviews, literature studies and questionnaires given to 33 respondents using SIKD with 6 dimensions of the Delone and Mclean models namely system quality, information quality, service quality, use, customer satisfaction and added benefits. The results showed that the dynamic archive information system (SIKD) implemented in the School of Vocation of Universitas Sebelas Maret has been good and effective to help manage the dynamic archive. The lowest score of 2.85 is obtained in service quality dimension, because there are some types of users that can use. The 90% respondents constituting 27 letter recorders highly affect the response based on the feedback given by Structural Official user type. An in-depth interview indicates that the constraint found related to the slow response is due to human resource or the preoccupation of structural officials. Meanwhile, the overall results of the calculations show that SIKD is effective in managing official scripts in vocational schools.

Authors: Nnawulezi Uche , Nwaechefu Hilary
Published: July 2023

The main aim of the article is to examine how the Nigerian lawyer will be better equipped through mandatory continuing legal education with regards to developing a cross- border approach to legal education in Nigeria. The article revealed the shortcomings of legal education in Nigeria and compared them with other legal education system around the globe. The article addressed three core questions that are particularly relevant to the Nigerian lawyer:  (1) who is considered a Nigerian lawyer under the Nigerian legal practitioners Act? Approaching this question allows examination of the relevant sections of the legal practitioners Act. The second and third questions addressed two issues that are crucial to the practice of law in Nigeria (2) how is the practice of law regulated? (3) Are there provisions for mandatory continuing legal education for the Nigerian lawyers? This approach revealed that there are provisions for mandatory continuing legal education in Nigeria, but in practice, it appears only to be figment of imagination. However, the article adopted a diagnostic approach based on a review of literatures and evidence-based analysis of legal education around the globe. In conclusion the article through the lens of cross-border legal education finds that there is a gap in repositioning the Nigerian lawyer through mandatory continuing legal education since it has remained a figment of imagination ever since it evolved. This article is expected to provide an understanding of the appropriate form of legal education for Nigerian lawyers to face contemporary challenges in the competitive market for lawyers.
Clinical Legal Education: An Examination of the Pedagogy of the Nigerian Law School and The Evaluation System
Authors: Aduak Yakusak
Published: July 2023

The Nigerian Law School is a vocational training institution, a finishing school for those who aspire to practice in the Nigerian Bar. The training is centered on procedural law, lawyering skills, and trial advocacy. To deliver that, the Institution keeps reviewing its curriculum to achieve its objectives. Presently, the curriculum is sandwiched in a nine (9) month program which includes about 20 weeks of orientation and lectures, 2 weeks of mock trials, 10 weeks of externships under Court and Law Office placements, 3 weeks of evaluation which includes the portfolio assessment of activities done or experienced during the externship period and final exams. The final examination at the Nigerian Law School is scenario-based Multiple Choice Questions (MCQ) and essay questions which form part of the final score and grade of a candidate. Students' externship activities are evaluated through the portfolio assessment exercise with a pass mark of 70%. Students who do not pass the portfolio assessment will not be called to the Nigerian Bar and will be required to repeat the externship exercise, but the score earned does not form part of the final marks for grading. It was found that as a result of the non-inclusion of mock trials and portfolio assessment in the final score of the students, many of the students do not show much commitment to the activities and as such miss out on the simulations and experiential learning that are key in preparing them for practice. It was also discovered that one of the challenges of including the scores of exercises like portfolio assessment and mock trials into the final score, is the integrity of the process. However, in clinical legal education, such activities need to be part of the final score. This work recommended some options for the effective evaluation of clinical activities for their inclusion in the final score of the students as well as other recommendations to make the legal training at the Nigerian Law School more clinical.

Published: July 2023

Diabetic Retinopathy (DR), juga dikenal sebagai penyakit mata diabetes, terjadi karena kerusakan pada retina akibat diabetes melitus yang berkepanjangan. DR dapat diklasifikasikan melalui gambar fundus retina. Namun, klasifikasi retinopati diabetik membutuhkan waktu yang tidak sedikit dan belum ada model yang memiliki performa tinggi dalam mengklasifikasikan DR. Tujuan dari penelitian ini mengusulkan model yang diharapkan memiliki tingkat akurasi yang lebih tinggi daripada penelitian sebelumnya. Metode yang digunakan adalah Convolutional Neural Network (CNN). Hasil evaluasi menunjukkan klasifikasi DR menggunakan CNN berarsitektur VGG-16 Net menghasilkan akurasi 96,24% sedangkan klasifikasi DR menggunakan CNN berarsitektur yang dimodifikasi menghasilkan akurasi 96.45%. Pada penelitian ini, akurasi model klasifikasi dapat ditingkatkan dengan menggunakan metode CNN berarsitektur termodifikasi.
Uji Aktivitas Fibrinolitik Jus Cacing Tanah (Lumbricus rubellus) Pada Tikus yang Diberi Asam Traneksamat
Authors: Nasirotuzahroh Ulin , Susanti R.
Published: July 2023

Trombosis merupakan pembentukan bekuan darah (trombus) yang tidak normal di pembuluh darah akibat ketidakseimbangan sistem hemostasis. Protease cacing (lumbrokinase) dari Lumbricus rubellus memiliki kemampuan fibrinolitik dengan aktivitas ganda, yaitu melarutkan fibrin dalam trombus dan mengubah plasminogen menjadi plasmin. Tujuan penelitian ini adalah untuk menganalisis pengaruh pemberian jus cacing tanah terhadap waktu perdarahan, waktu pembekuan, dan jumlah trombosit pada tikus yang diberi asam traneksamat (TXA). Penelitian ini menggunakan postest randomized controlled group design dengan rancangan acak lengkap (RAL). Sebanyak 15 ekor tikus jantan galur Wistar dibagi menjadi 5 kelompok, yaitu kelompok kontrol normal (KN) yang tidak diberi perlakuan, kelompok kontrol positif (KP) diberi TXA 50 mg/kgBB dan aspirin 100 mg/kgBB, dan kelompok perlakuan jus cacing yang diberi TXA 50 mg/kgBB kemudian masingmasing diberi jus cacing 1,5 gram/kgBB (P1); 2 gram/kgBB (P2); dan 2,5 gram/kgBB (P3). Sediaan uji diberikan sekali sehari secara oral selama 7 hari. Pengambilan darah dilakukan pada hari ke-7 untuk pemeriksaan waktu perdarahan, waktu pembekuan, dan jumlah trombosit. Masing-masing data dianalisis dengan one-way anova dilanjutkan uji LSD. Hasil penelitian menunjukkan bahwa pemberian jus cacing tanah pada tikus yang diberi asam traneksamat berpengaruh signifikan meningkatkan waktu perdarahan dan waktu pembekuan darah, namun tidak berpengaruh signifikan menurunkan jumlah trombosit. Hal ini menunjukkan bahwa cacing tanah berpotensi dikembangkan sebagai obat terapi fibrinolitik yang aman tanpa risiko perdarahan.

Im Jahr 2013 jährten sich die Machtübernahme der Nationalsozialisten 1933 zum 80., die Reichspogromnacht vom 9. November 1938 zum 75. und die als „Operation Gomorrha“ bekannten Luftangriffe alliierter Verbände auf Hamburg im Sommer 1943 zum 70. Mal. Unter dem Leitgedanken „Hamburg erinnert sich 2013“ fand das gesamte Jahr über eine Vielzahl von Gedenkveranstaltungen statt. Die Universität Hamburg war durch mehrere ihrer Einrichtungen am Veranstaltungsprogramm im Gedenkjahr beteiligt. Für ihre zentrale Veranstaltung wählte sie als Bezugsdatum den 7. April 1933, jenen Tag, an dem das „Gesetz zur Wiederherstellung des Berufsbeamtentums“ in Kraft trat – die Grundlage für die Entlassungen von „nicht arischen“ und politisch unerwünschten Hochschullehrerinnen und -lehrern in Deutschland. Dieser Band versammelt die vier am 8. April 2013 anlässlich der Veranstaltung gehaltenen Reden. Die Gedenkveranstaltung vom 8. April 2013 und ihre Dokumentation verstehen sich als Teil einer seit dreißig Jahren intensiv betriebenen Beschäftigung der Universität Hamburg mit ihrer Geschichte im „Dritten Reich“ – eine Auseinandersetzung, die es über Generationenwechsel hinweg fortzuführen und immer wieder neu zu beleben gilt.
Los comuneros del bosque mesófilo mexicano evalúan una década de pagos por servicios ambientales: la importancia de la soberanía indígena en los programas de conservación
Authors: Denham Diana
Published: July 2023

Los programas de pagos por servicios ambientales (PSA) han adoptado una variedad de formas que dependen de muchos factores mediadores como la política nacional y local, la tenencia de la tierra, la acción colectiva regional, la capacidad de los intermediarios y el contexto socioecológico. Como era de esperar, esta diversidad ha producido experiencias mixtas, muchas de las cuales no han logrado el doble objetivo de beneficios ambientales y sociales, y algunas incluso han causado consecuencias adversas. Este estudio examina un caso inusitado de PSA que ha contribuido tanto a la conservación de los bosques como a los medios de vida comunitario. En este estudio, los dueños de bosques comunitarios o comuneros de cuatro comunidades indígenasubicadas en el bosque mesófilo mexicano evalúan su participación durante diez años en un programa público de PSA para apoyar a la gestión de cuencas hidrográficas. Se argumenta que la atención a la soberanía y autodeterminación de las comunidades indígenas durante la implementación del programa contribuyó a la obtención de beneficios socioambientales ampliamente apreciados. Aunque muchos programas de PSA se implementan en comunidades  indígenas, los debates académicos rara vez se han ocupado directamente de estos temas.
Enzyme promiscuity approaches to predict metabolic pathways in the human gut microbiota.
Authors:   , Balzerani Francesco
Published: July 2023

Metabolism is the whole set of reactions that take place in an organism. Understanding how humans digest food and absorb nutrients is complex and challenging. The role of the different communities of microorganisms that reside in the human being, called microbiota, has gained growing interest in the last decade. In particular, the human gut microbiota has been linked to several diseases and syndromes, which has largely motivated the study of the interaction between diet, gut microbiota metabolism and health from very different angles. In the area of System Biology, the release of high-quality metabolic reconstructions of the human gut microbiota has opened new avenues to address this question. However, they are still in their infancy, and further developments are required to obtain more comprehensive metabolic models. In this doctoral thesis, the main objective is to develop computational tools to complete these metabolic reconstructions and improve the annotation of important dietary compounds degraded by the human gut microbiota. This work is divided into two parts. The first part focuses on System Biology and enzyme promiscuity with the aim of improving metabolic reconstructions of the human gut microbiota. We present AGREDA v1.1, a new metabolic reconstruction that includes predicted chemical transformations from a popular enzyme promiscuity algorithm called RetroPath RL. The new draft AGREDA v1.1 allows a better representation of phenolic compounds, a relevant class of compounds for both nutrition and health. By means of untargeted metabolomics, we validated the ability of AGREDA v1.1 to predict output microbial compounds in the human gut microbiota. Then, we introduce PROXIMAL2, a novel enzyme promiscuity algorithm that overcomes the limitations of PROXIMAL, a promising previously published algorithm, but it was unable to be applied to our problem of phenolic compound degradation in the human gut microbiota. In particular, PROXIMAL2 overcomes the dependency on KEGG database and extends the scope of application to more complex enzymatic reactions. We obtained complementary results to the ones obtained with RetroPath RL, proposing new tentative degradation pathways for phenolic compounds in the human gut microbiota. The second part of this doctoral thesis is focused on the development of tools to analyze the 16S rRNA gene-sequencing data using metabolic reconstructions of the human gut microbiota. Specifically, we present a novel Python package called q2-metnet, which contextualizes 16S rRNA gene-sequencing data into metabolic networks and provides a quantitative score for reactions and subsystems. By means of different metabolic reconstructions, users can characterize data samples and extract functional features to differentiate between clinical conditions.
Histórias de vida de mulheres Sem Terra: divisão sexual do trabalho na agroecologia
Authors: Coradin Cristiane , Schwendler Sônia Fátima
Published: July 2023

Resumo: Neste artigo, analisamos a divisão sexual do trabalho no trabalho agroecológico de mulheres que vivem em territórios de Reforma Agrária do Paraná. Os dados de campo apontam para o aumento da autonomia, ‘agência’ e subjetividade ativa das mulheres. Entretanto, identificamos persistências de divisões sexuais do trabalho patriarcais. Esse quadro conduz à ampliação de jornadas de trabalho e esgotamento do corpo das mulheres. Além disso, identificamos redução da organização sociopolítica e migração para o âmbito da produção e comercialização agroecológica. Essas desigualdades são reduzidas por fatores geracionais, escolaridade, formação de gênero e transitoriedade campo-cidade. Mediante tal cenário, a reivindicação feminista da divisão sexual do trabalho igualitária é relevante na luta política de gênero, pela terra, agroecologia e decolonial.
Cenários de aplicação da Lei Geral de Proteção de Dados Pessoais às folksonomias
Authors: Ferreira Herbert Alcântara , Sales Rodrigo de
Published: July 2023

Resumo: No universo de Sistemas de Organização do Conhecimento, ferramentas voltadas à representação e organização da informação para sua posterior recuperação, surgem as folksonomias, mecanismos computacionais que fornecem e armazenam tags criadas pelos próprios usuários da Web para indexar recursos online. Por serem instrumentos abertos e voltados ao compartilhamento social de etiquetas e objetos indexados, levanta-se a preocupação com a privacidade nesses ambientes. Nesse sentido, o presente trabalho investiga a existência de cenários de folksonomias em que existem informações pessoais e, portanto, necessitam do amparo da Lei Geral de Proteção de Dados Pessoais. Ademais, se houver tais possibilidades, procura-se descrever quais principais regras da lei que devem ser aplicadas aos ambientes de tagging na Web. Para realização desta pesquisa, utilizou-se o método de abordagem dedutivo, a metodologia procedimental comparativa e a técnica de pesquisa bibliográfica. Conclui-se que há casos possíveis de presença de dados pessoais em folksonomias, seja quando esse tipo de informação encontra-se em formato de tags, seja na sua inclusão em recursos indexados (textuais, gráficos, audiovisuais, etc.). Ademais, chegou-se à conclusão de que nem todas as regras da Lei Geral de Proteção de Dados Pessoais são aplicáveis a esses sistemas, mas que a lei deve ser observada no que for possível, para dirimir riscos de violações, sendo que a exposição ilegítima das informações pessoais é a principal delas.

Published: July 2023

Abstract Objective to analyze the effect of burden, stress, and depressive symptoms on the health characteristics of older adult caregivers of older adults. Method A quantitative and longitudinal study was conducted with 127 older adult caregivers to analyze the effect of burden, stress, and depressive symptoms on their health characteristics. The variables assessed included health characterization, burden, depressive symptoms, and stress. A linear regression model and Poisson test were employed, with a significance level set at 5%. Results The findings revealed that an increase of one point in the burden scale score was associated with a 0.030 increase in the number of diseases (p=0.020) and an increased risk of chronic pain (p=0.005). Similarly, a one-point increase in the stress scale score was associated with a 0.058 increase in the number of diseases (p=0.001), as well as an increased risk of a poor subjective health assessment (p=<0.001) and chronic pain (p=<0.001). Furthermore, an increase in the score on the depressive symptoms scale was associated with an increase in the number of diseases (p=<0.001), risk of falls (p=0.009), poor subjective health assessment (p=<0.001), and chronic pain (p=<0.001). Conclusions and implications for practice The worsening estimate in the scores of psychological variables poses a risk to the deterioration of caregivers’ physical health characteristics. The findings underscore the need for the development of public policies aimed at improving the quality of life for older adult caregivers.

Authors: Romig Karen Laiz Krause , Weiduschadt Patrícia
Published: July 2023

Resumo O presente artigo traz como temática a cultura material escolar de quatro instituições educacionais luteranas da região geográfica da Serra dos Tapes, no sul do estado do Rio Grande do Sul, entre os anos de 1938 a 1971. O objetivo central deste escrito é discutir as características da cultura escolar destas escolas que possuíam características singulares, pois oriundas de um processo histórico de colonização alemã e pomerana, tiveram a intervenção patriótica da nacionalização do ensino, e carregavam as marcas da etnicidade do grupo étnico que as frequentava. A metodologia de pesquisa conta com o uso da história oral e análise documental. Ao longo do estudo percebeu-se que a cultura escolar dessas instituições é específica, com classes multisseriadas que valorizavam o ensino da religião, da matemática, da leitura, da escrita e orientações cívicas, visando uma formação básica para que o aluno atuasse como agricultor camponês com sua família.

Authors: Philippi Carolina Cechella
Published: July 2023

Resumo Este artigo analisou a publicação da Revista de Ensino Primário (1922) catarinense, atentando para os dispositivos narrativos e as indicações para organização da materialidade escolar em meio às comemorações do Centenário da Independência nacional. Interessou, pois, inquirir as formas pelas quais a revista apresentou dados, citações e referências na tentativa de construir a legitimidade necessária para o exercício do mando por parte da Diretoria Geral da Instrução Pública, então capitaneada por Henrique da Silva Fontes, bem como de dar subsídios à prática docente, sobretudo na instrução primária. Como considerações finais, assinala para as disputas mapeadas por meio das orientações fornecidas na publicação, bem como para o esforço narrativo em inserir a história e a instrução catarinense em um cenário nacional de luta contra o analfabetismo.
EFEITOS DA TRANSPARENCIA SOBRE A MORTALIDADE INFANTIL BRASILEIRA: UMA ABORDAGEM DE REGRESSÃO DESCONTINUA
Authors: Franco Cleiton , Nishimura Fabio
Published: July 2023

A transparência e a garantia do acesso à informação são medidas determinantes para o fortalecimento da democracia e para a melhoria da gestão pública. O debate sobre transparência pública no Brasil ainda se restringe a aspectos da execução orçamentária e financeira dos entes públicos. A Lei de Acesso à Informação (LAI) sancionada em 18 de novembro de 2011, entrou em vigor em 16 de maio de 2012 e regulamentou o direito de acesso a dados e informações das entidades públicas, consolidando o processo de transparência. A Lei avança no conceito de ferramenta para a melhoria da gestão pública e da qualidade dos serviços prestados aos cidadãos. O presente trabalho busca analisar o efeito da Lei de Acesso à informação sobre a mortalidade infantil. A estratégia empírica utiliza o modelo de regressão descontinua, através de um painel de dados municipal entre os anos de 2006 a 2016. Os resultados demonstram que ocorrem reduções das mortes infantis e atingem um percentual entre 28,5% a 29,7% para crianças de 0 a 27 dias de vida, e de aproximadamente 12,7% para crianças entre 28 a 360 dias de vida.
The JOBS Act and the boost for start-up fundraising: A Regression Discontinuity design approach
Authors: Franco Cleiton , Sampaio Gustavo Ramos
Published: July 2023

Crowdfunding plataforms are becoming increasingly popular, allowing micro-entrepreneurs to raise money to fund projects in various categories. The present study aims to explorar the effects of the JOBS (Jumpstart Our Business Startups, JOBS) Act, which fostered the crowdfunding model by smoothing several securities regulations, on fundraising, attraction of backers and fundraising categories, seeking to identify ifthere has been a change in the backer profile for the crowdfunding market, especiallyin the Kickstarter.com platform. The empirical analysis used a Regression Discon- tinuity Design model. The discontinuity lies in verifying the incentive provided by the increase in the number of backers and the volume of fundraising after the Act came into effect. When assessing the results, it could benoticed that the Act affected fundraising levels for start-up projects in 75%. In a similar way, it affected the number of backers in 59%. In order to test model specification, robustness tests were performed by fundraising category. The Design, Video Games and Technology categories presented both positive and significant results and reinforced the title of capital increase. There was an increase of US$ 22,599 in the coefficient, which represents a variation of 106% in relation to the average for the Design category. For the Video Games category, the increase was of US$ 42,523, or a variation of 222% in relation to the average. For the Technology category, it was observed that the effect generates an increase of US$ 52,733, or a variation of 174% in relation to the average. Looking at project quality and how it might attract backers, resultsfor successful and unsuccessful projects and for average fundraising were estimated. The results indicate a significative increase in fundraising for successful projects and that they also present evidence on a higher fundraising average. The growth of the crowdfunding movement associated with the JOBS Act brought more institutional and legal security to micro-entrepreneurs, backers and users of crowdfunding plat- forms, demonstrating a positive effect for projects hosted on the Kickstarter.com platform, boosting their volume of fundraising.
O cristão-novo Cadornega e sua obra sobre as guerras angolanas no século XVII
Authors: Vainfas Ronaldo , Franco Roberta Guimarães
Published: July 2023

Resumo: O artigo analisa a trajetória de Antônio de Oliveira Cadornega, autor de História geral das guerras angolanas (1680). Examinamos aspectos da obra ligados às preocupações do autor - as guerras envolvendo os portugueses, os holandeses, o reino do Congo e o de Angola - destacando a sua posição lusocêntrica. Para tanto, utilizamos a edição impressa de 1972 e a bibliografia sobre a obra e seu autor. Buscamos as conexões entre a escrita do texto e a crise política portuguesa no século XVII, inclusive a inquisitorial, bem como entre a história de suas edições e o contexto português no século XX. O foco de nossa reflexão reside, porém, na condição de cristão-novo do autor, por linha materna, e na possibilidade de ter praticado o criptojudaísmo, seja na juventude, em Vila Viçosa, seja na África, assim como o grupo de cristãos-novos portugueses estudado por Horta e Mark na Senegâmbia, em The Fortgotten Diáspora (2011).
Gilberto Freyre in the press: an Iberian idea of the city, from 1920s Recife to 1950s Lisbon
Authors: Schneider Alberto Luiz
Published: July 2023

Abstract: The goal of this article is to investigate the work of Gilberto Freyre about a specific topic, that is, the narration of cities through the lens of the press, an object of study that is not detached from the most fundamental pillars of his work, marked by an empathetic look at the past and by the defense of the Iberian heritage, considered hybrid and plastic. The theme of cities was present in Freyre’s books, such as the Guia prático, histórico e sentimental da cidade do Recife (1934) but was also subject of pages and pages in the press, a theme understudied by the specialized critic. The sensitivity to the urban aspect in his journalistic activity - with emphasis on Recife in the 1920s and Lisbon in the early 1950s - constitute the analytical focus of this contribution.
HALL AND ION EFFECTS ON BIOCONVECTIVE MAXWELL NANOFLUID IN NON-DARCY POROUS MEDIUM
Authors: Sangeetha E. , De Poulomi , Das Ranjan
Published: July 2023

Usage of nanoparticles along with bioconvection is one of the emerging techniques for heat transfer augmentation. The presence of Hall and ion effects becomes imperative and cannot be neglected on strong applied magnetic fields. This article intends to perceive the Hall and ion-slip effects on Maxwell nanofluid carrying gyrotactic microorganisms and nanoparticles. The flow of fluid is well chosen in a non-Darcy porous ambience. Bioconvection phenomenon, thermal radiation, heat generation/absorptions effects are studied with first-order chemical reaction and a consistent magnetic field is administered within the numerical investigation. The governing nonlinear partial differential equations are converted into ordinary differential equations using similarity transformations. The fifth-order Runge-Kutta-Felhberg method with shooting technique is adapted to deal with the numerical solution. The graphical representation of pertinent parameters brings about reduced motion of the fluid and an improved thermal state of the fluid for the magnetic parameter, whereas the ion parameter is conversely impacted. The bioconvection Lewis number, Peclet number, and the microorganism's concentration difference parameter are observed to respond in downscale for the density of microorganism profile.

Published: July 2023

The demand for ornamental stone material has led to an increase in the amount of rock mass being processed. However, the production of lapidary works and jewelry result in a significant amount of waste. This study aims to investigate the material composition and physical and mechanical properties of the solid wastes generated during the processing of dolomite type nephrite in the Vitim region. The accumulation of such waste leads to increased costs of transportation, storage, security, and negative environmental impact. The majority of dolomite type nephrite deposits are located in the Northwest, Northeast, and South of China, in South Korea, Australia, Italy, and Poland, with a large deposit in the Vitim region of Russia. In this study, the waste from the Kavoktinsky deposit, the most productive in Russian, was used. A visual and petrographic examination of nephrite, skarn and amphibolite which are components of the solid waste, was conducted. The macro- and microchemical composition of nephrite of different colors was studied, and X-ray phase analysis was performed. The decorative properties of the waste were determined. A radiation and hygienic certificate was obtained. The waste has a crushability grade of 1200, abrasion grade of I1, and frost resistance of F400. The study has shown that the waste does not contain grains of incompetent rocks, clay, dust, and clay particles. The solid waste form the Vitim nephrite processing is of high quality and meets the requirements of GOST 8267-93, except for an increased content of flagstone (flattened) and large size fragments. It can be used for the production of ordinary, decorative, and mosaic concrete, decorative plates, interior decoration of premises, bathrooms, and saunas, and the manufacture of souvenir products. However, further research is needed to investigate the application of the waste as a raw material for stone casting and a slow-release fertilizer. The utilization of this waste not only solves the problem of waste disposal but also improves economic performance of mineral extraction.
Online deceptive advertising and consumer protection in South Africa - The law and its shortcomings?
Authors: Mupangavanhu Yeukai , Kerchhoff Dominique
Published: July 2023

E-commerce and e-marketing has grown significantly over the past few years. More businesses are moving away from original forms of marketing tools such as newspapers, magazines, billboards and televisions and instead prefer online platforms such as social media. The article focuses on false, misleading and deceptive online marketing representations. It examines the legislative framework that seeks to protect online consumers in South Africa in terms of the Electronic Communications and Transactions Act 25 of 2002 (ECTA), the Consumer Protection Act 68 of 2008 (CPA) as well as the Social Media Code1 of the Advertising Regulatory Board (ARB). It is recommended that although a consolidated statute that makes provision for both offline and online consumers would be ideal, the current provisions in ECTA could also be reviewed to ensure that they are in line with the new developments in marketing trends such as influencer marketing. The Social Code of the ARB is also important to complement ECTA and the CPA, as well as to promote the overall protection of consumers in South Africa.
