Published: December 2022

Background: There is an increasing number of liver injury cases resembling autoimmune hepatitis (AIH) following SARS-CoV-2 vaccination; however, an association has not yet been established. Methods/Materials: A literature review was performed to identify articles regarding the association of AIH with vaccination, emphasizing on SARS-CoV-2 vaccines, and the proposed mechanisms. We then performed a literature search for AIH-like cases following SARS-CoV-2 vaccination, and we evaluated the included cases for AIH diagnosis using simplified diagnostic criteria (SDC), and for vaccination causality using the Naranjo score for adverse drug reactions. Results: We identified 51 AIH-like cases following SARS-CoV-2 vaccination. Forty cases (80%) were characterized as “probable”, “at least probable”, or “definite” for AIH diagnosis according to SDC. Forty cases (78.4%) were characterized as “probable”, four (7.8%) as “possible”, and three (5.8%) as “definite” for vaccine-related AIH according to the Naranjo score. Conclusion: SARS-CoV-2 vaccine-related AIH carries several phenotypes and, although most cases resolve, immunosuppressive therapy seems to be necessary. Early diagnosis is mandatory and should be considered in any patient with acute or chronic hepatitis after SARS-CoV-2 vaccination, especially in those with pre-existing liver disease.

Published: December 2022

Background: We estimated real-world vaccine effectiveness (VE) against COVID-19 infection, hospitalization, ICU admission, and death up to 13 months after vaccination. VE before and after the emergence of Omicron was investigated. Methods: We used registered data from the entire Swedish population above age 12 (n = 9,153,456). Cox regression with time-varying exposure was used to estimate weekly/monthly VE against COVID-19 outcomes from 27 December 2020 to 31 January 2022. The analyses were stratified by age, sex, and vaccine type (BNT162b2, mRNA-1273, and AZD1222). Results: Two vaccine doses offered good long-lasting protection against infection before Omicron (VE were above 85% for all time intervals) but limited protection against Omicron infection (dropped to 43% by week four and no protection by week 14). For severe COVID-19 outcomes, higher VE was observed during the entire follow-up period. Among individuals above age 65, the mRNA vaccines showed better VE against infection than AZD1222 but similar high VE against hospitalization. Conclusions: Our findings provide strong evidence for long-term maintained protection against severe COVID-19 by the basic two-dose schedule, supporting more efforts to encourage unvaccinated persons to get the basic two doses, and encourage vaccinated persons to get a booster to ensure better population-level protection.
Policy and Guideline Review of Vaccine Safety for COVID-19 in Pregnant Women in Southern Africa, with a Particular Focus on South Africa
Authors: Chimukuche Rujeko , Nkosi Busisiwe , Seeley Janet
Published: December 2022

Pregnant and lactating mothers have historically been excluded from clinical trials. To understand the shift from excluding to including this population in COVID-19 vaccine trials, we conducted a review of guidance issued by countries in southern Africa over the last three years. We conducted a review of documents and official statements recorded on Ministries of Health websites, and social media platforms, the World Health Organisation website, the COVID-19 Maternal Immunisation tracker and the African Union official webpage. Search terms included COVID-19 vaccination policies, guidelines for pregnant and lactating women, COVID-19 vaccination trials and pregnant women. We retrieved and reviewed policies, guidelines, and official statements from 12 countries. We found inconsistencies and incomplete guidance in respect to the inclusion of pregnant and lactating mothers in COVID-19 vaccine trials from the selected countries. Of the twelve countries reviewed, Namibia and South Africa had clear guidance on vaccination plans and implementation for pregnant women, and their inclusion in COVID-19 vaccine trials. Explicit and clear guidelines are critical in communicating changes in policy towards those deemed vulnerable for them to participate in vaccine trials. This review provides lessons for future pandemics on managing changes in guidance towards those groups historically excluded from vaccine and clinical trials.
Microparticle RSV Vaccines Presenting the G Protein CX3C Chemokine Motif in the Context of TLR Signaling Induce Protective Th1 Immune Responses and Prevent Pulmonary Eosinophilia Post-Challenge

Published: December 2022

Layer-by-layer microparticle (LbL-MP) fabrication was used to produce synthetic vaccines presenting a fusion peptide containing RSV G protein CX3C chemokine motif and a CD8 epitope of the RSV matrix protein 2 (GM2) with or without a covalently linked TLR2 agonist (Pam3.GM2). Immunization of BALB/c mice with either GM2 or Pam3.GM2 LbL-MP in the absence of adjuvant elicited G-specific antibody responses and M2-specific CD8+ T-cell responses. Following challenge with RSV, mice immunized with the GM2 LbL-MP vaccine developed a Th2-biased immune response in the lungs with elevated levels of IL-4, IL-5, IL-13, and eotaxin in the bronchoalveolar lavage (BAL) fluid and a pulmonary influx of eosinophils. By comparison, mice immunized with the Pam3.GM2 LbL-MP vaccine had considerably lower to non-detectable levels of the Th2 cytokines and chemokines and very low numbers of eosinophils in the BAL fluid post-RSV challenge. In addition, mice immunized with the Pam3.GM2 LbL-MP also had higher levels of RSV G-specific IgG2a and IgG2b in the post-challenge BAL fluid compared to those immunized with the GM2 LbL-MP vaccine. While both candidates protected mice from infection following challenge, as evidenced by the reduction or elimination of RSV plaques, the inclusion of the TLR2 agonist yielded a more potent antibody response, greater protection, and a clear shift away from Th2/eosinophil responses. Since the failure of formalin-inactivated RSV (FI-RSV) vaccines tested in the 1960s has been hypothesized to be partly due to the ablation of host TLR engagement by the vaccine and inappropriate Th2 responses upon subsequent viral infection, these findings stress the importance of appropriate engagement of the innate immune response during initial exposure to RSV G CX3C.

The thermal stability of newborns is an essential parameter that can be recorded to evaluate neonatal care. Knowing the thermal windows to evaluate and maintain a constant temperature helps significantly reduce neonatal mortality. This study aimed to assess the superficial temperature alterations in the distinct thermal windows of puppies with mothers of diverse weights and their repercussions. We evaluated the superficial temperature using infrared thermography at eight thermal windows and seven different times: when wet due to the fetal fluid immediately after birth until 24 h of life in newborn puppies from bitches divided into four bodyweight groups. The results revealed a positive correlation between the dam’s weight and the ability to achieve thermostability in the newborn puppies in all the evaluated thermal windows. The time effect showed the lowest temperatures when the puppies were still wet, a gradual increase, and the highest temperature at 24 h after birth. The thermal windows with the highest temperatures were abdominal, thoracic, nasal, and upper left palpebral, and those with the lowest were the thoracic limb brachial biceps, thoracic limb elbow, metacarpal, and femoral pelvic limb. A significant increase in the temperatures in the thermal windows of the abdominal, thoracic, and upper left palpebral immediately after ingesting colostrum was observed. The weight of the dams is an important factor that positively intervenes in the thermoregulatory capacity of the puppies, especially when newborns are dry and have been passed 24 h after birth.

Published: December 2022

Escherichia coli (O78) is an avian pathogenic Escherichia coli (APEC). It can cause perihepatitis, pericarditis, septicemia and even systemic infections in the poultry industry. With the incidence of antibiotic resistance reaching a crisis point, it is important to find alternative treatments for multidrug-resistant infections. The use of phages to control pathogens is a promising therapeutic option for antibiotic replacement. In this study, we isolated a lytic phage called vB_EcoS_GN06 from sewage. It lysed APEC GXEC-N22. Transmission electron microscopy showed that the phage belongs to family Siphoviridae. Phage GN06 has a 107,237 bp linear double-stranded DNA genome with 39.2% GC content and 155 coding sequences. It belongs to the genus Tequintavirus, subfamily Markadamsvirinae. The multiplicity of infection of 0.01 and the one-step growth showed that the latent time is 60 min and the burst size is 434 PFU/cell. Temperature and pH stability tests showed that phage GN06 was stable in the range of 4 °C–60 °C and pH 5–9. GN06 showed significant inhibition of APEC both within the liquid medium and in biofilm formation. These results suggest that phage GN06 has the potential to control bacterial pathogens. Thus, GN06 has the potential to be a new potential candidate for phage therapy.
Does Father Christmas Have a Distinctive Facial Phenotype?
Authors: Wright Thomas , Law Chris , Wright Ben , Wright Barry
Published: December 2022

We investigated whether Father Christmas has a distinguishable facial phenotype by performing a cross-sectional cohort study examining the facial feature vectors of all publicly available photographs obtained from a google image search of individuals meeting our eligibility criteria presenting as Father Christmas compared with other adult and elderly bearded men. Facial feature vectors were determined using the open-source OpenFace facial recognition system and assessed by support vector machines (SVM). SVM classifiers were trained to distinguish between the facial feature vectors from our groups. Accuracy, precision, and recall results were calculated and the area under the curve (AUC) of the receiver operating characteristic (ROC) were reported for each classifier. SVM classifiers were able to distinguish the face of Father Christmas from other adult men with a high degree of accuracy and could discriminate Father Christmas from elderly bearded men but with lower accuracy. Father Christmas appears to have a distinct facial phenotype when compared to adult men and elderly bearded men. This will be reassuring to children who may be keen to recognise him but raises some interesting questions about the careful use of two-dimensional facial analysis, particularly when employed to explore the relationships between genotype and facial phenotype in a clinical dysmorphology setting.
Recycled Bottle Glass Wastes as Precursors for Porous Alumina Glass Ceramics Synthesis
Authors: Vancea Cosmin , Mosoarca Giannin
Published: December 2022

This research presents a new solution to use bottle glass wastes together with aluminum hydroxide for porous alumina glass ceramics synthesis. The firing of the samples was conducted at three temperatures: 800, 1000 and 1200 °C. The effect of the bottle waste glass addition on the firing shrinkage, apparent density porosity, chemical stability and compression strength of the sintered samples was investigated. The dimensional stability of the samples, varying between 4.75–11.87% is positively affected by waste glass/alumina substitution ratio. Higher amounts of glass waste lead to higher apparent densities, up to 1.80 g/cm3 and lower apparent porosities, around 33.74%, depending on the heat treatment temperature. All the studied glass ceramics have very good chemical stability that increase with the glass waste/alumina ratio. The compression strength of the obtained samples, ranging between 4.72–24.20 N/mm2 is negatively affected by increasing the glass waste amount due to its brittle behavior. The obtained results suggest the viability of the proposed recycling alternative for bottle glass waste together with aluminum hydroxide as porous alumina glass ceramics.

Authors: McKenzie Bryan , Kelouwani Sousso , Gaudreau Marc-André
Published: December 2022

In this paper, we propose the use of a neural network to identify lateral skidding events of road vehicles used during winter driving conditions. Firstly, data from a simulation model was used to identify the essential vehicle dynamics variables needed and to create the network structure. Then this network was retrained to classify real-world vehicle skidding events. The final network consists of a 3 layer network with 10, 5 and 1 output neurons 13 inputs, 4 outputs and a 5 step time delay. The retrained network was used on a limited set of real vehicle data and confirmed the effectiveness of the network classifying lateral skidding events.

Caste in a new light
Authors: Shah Prakash
Published: December 2022

Advocates of multiculturalism claim that it supports the rights of cultural minorities and the public recognition of cultural differences. However, this article shows that this cannot be true of Indian culture as it has become transported to Britain, where multiculturalism actually poses a threat to it. Using the resources of the research programme of the Ghent School on the comparative study of India and Europe, this article substantiates this claim by showing how the dominant conception of cultural differences as well as the classical conception of the Indian caste system, which takes over the Indian social structures of jati, are both imported by multiculturalist thought and practice. The concretizing of multiculturalism in the form of anti-discrimination law is not only anticipated by a destructive politics of identity, but the law itself can be used to foster the destruction of Indian culture on the pretext of targeting the discriminatory caste system.
Economy: Exceptionality as a driver of structural change in the Basque Autonomous Community and Navarre
Authors: Longas Juan Carlos
Published: December 2022

The global pandemic generated a crisis of still unpredictable consequences, further aggravated by the war in Ukraine. In 2008 a broad consensus had emerged on the need for far-reaching reforms, which basically meant doing away with the neoliberal consensus that had prevailed since the 1980s, although the chances of recovery were soon made dependent on the economic cycle. Once again, the current crisis is calling into question the quality and effectiveness of the social protection system and the welfare state itself. The responses seem to indicate a change of direction, towards safeguarding and strengthening the public sector. The Basque Country and Navarre are affected too. Two symptoms of this are the reinforcement of investment in health, which implies reversing previous cuts, and the approval of systems to cover the most disadvantaged groups. These measures require, however, the backing of other structural measures, particularly fiscal ones.
The exceptional situation of victims of trafficking for the purpose of sexual exploitation during the state of alarm in the Spanish State
Authors: Orbegozo Izaskun
Published: December 2022

Before the pandemic, the legislation and instruments (plans, guidelines and protocols) implemented in the field of human trafficking, at global and local level, had the objective of guaranteeing the rights of the victims in order to assist and protect them in their situation of special vulnerability. However, the health crisis caused by COVID-19 and the declaration of the State of Alarm in Spain have generated a worsening of their personal situation and, consequently, other social norms and measures have been adopted to protect and palliate the damages suffered in this exceptional situation. For this reason, this article analyzes, from a gender perspective, the effects of both the legal reforms and the assistance measures adopted by the Ministry of Equality and social organizations for women victims of trafficking for sexual exploitation during the COVID-19 pandemic, making special mention of the Basque context.

When corruption hits the judiciary: A global perspective on access to justice and corruption
Authors: Pedersen Karin , Johannsen Lars
Published: December 2022

This study asks if the level of corruption relates to perception of access to justice. Looking at the supply side of access to justice, a corrupt judicial system will imply that the less well-off cannot afford to gain their rights. However, does corruption widen a justice gap? Studies show that corruption relates to democracy, wealth and equality. The link between corruption and the judiciary is less studied. This study explores the general global relations statistically with use of data from 113 countries. Using multiple regression, it corroborates the classical debate on inequality and equal access to justice but critically contribute to this debate by finding that corruption has an independent and strong relation to access to justice. However, it also finds that income inequality continues to be of importance. This finding is not trivial but suggests that anti-corruption and equality policies may improve access to justice.
LGBTQIA+ asylum: From recognition to data provision in Brazil
Authors: Nicolau Pimentel Alamino Felipe , Zonato Villas Boas Izabela
Published: December 2022

LGBTQIA+ asylum is a reality in Brazil, although it is not expressly included in the convention. Starting with historical research, the article shows how LGBTQIA+ asylum has been consolidated in International Law and, specifically in Brazil, as a country where there are also cases of homophobia and transphobia, LGBTQIA+ asylum is guaranteed, even if the information requested from the Federal Police and the National Committee for Refugees from Brazil do not currently indicate whether the number of concessions specifically for these groups has increased or decreased. Addressing the cliquet effect, it demonstrates the impossibility of retroaction in terms of Human Rights, preventing the denial of the granting of asylum in Brazil to this people, which is the distinctive focus of the research. The deductive method, combined with qualitative analysis of primary sources, such as official documents, and bibliographical sources were used to achieve the results.

Authors: Rohmatulloh Rohmatulloh , Nindiasari Hepsi , Fatah Abdul
Published: December 2022

This research aims to determine the impact of flipped classroom learning models on students' problem-solving abilities. The research design used is a pseudo-experiment with a posttest-only control group. This study's population consisted of grade VIII students from SMP Serang for the 2021/2022 school year. Samples were determined using cluster random sampling techniques to obtain experimental and control classes. Data were gathered by administering a mathematical problem-solving ability test to students in the form of a description test at the end of the study. Based on posttest data, students' average mathematical problem-solving ability using a flipped classroom approach was 76.97 points. In comparison, students' average mathematical problem-solving ability using traditional learning was 64.33 points. The results of data analysis using a t-test with a 5% significance level revealed that the tcount is higher than ttable. This means that students who participate in flipped classroom learning have better problem-solving skills than students who use traditional learning models. As a result, flipped classroom model learning affects students' mathematical problem-solving abilities.
Risks of Ill-Being Posed by Mobile Internet Usage to Younger Schoolchildren
Authors: Vyatleva Olga A. , Kurgansky Alexander M.
Published: December 2022

Background: Modern children are noted for increasing mobile Internet usage, during which the electromagnetic field exposure is aggravated by the exposure to the phone screen light, both affecting children’s well-being. The relevance and purpose of this study have been determined by insufficient knowledge of effects of this combined exposure and the lack of data on the patterns of mobile Internet usage detrimental to younger schoolchildren’s health.
Objective: To assess the impact of mobile Internet usage on the well-being of elementary students and to establish its parameters posing risks of children’s ill-being.
Materials and methods: In 2017–2019, a cross-sectional study of 140 Moscow first to fourth graders was conducted using questionnaires to establish the parameters of smartphone use for voice calls and access to mobile Internet as well as the frequency
of health complaints and neurological history. In addition, the energy flux of electromagnetic fields generated by the children’s cell phones was measured. In 112 students with a normal neurological history, of which 77 used and 35 did not use
mobile Internet, the applied statistical methods revealed the parameters of mobile Internet usage posing risks of ill-being, i.e. having certain health complaints several times a week.
Results: Mobile Internet usage was associated with sleep dissatisfaction in the children (OR = 6.81; 95 % CI: 1.91–24.22), which occurred when the monthly Internet usage exceeded 8.62 hours and a session length was more than 10 minutes. Daily Internet usage increased the risk of forgetfulness (OR = 5.23; 95 % CI: 1.43–19.19) while higher levels of smartphone radiation correlated with both sleep dissatisfaction and forgetfulness. A low intensity of mobile Internet usage (less than 17.74 hours a
month) was associated with low mood in the study population.
Conclusion: To prevent ill-being, younger students shall be advised to exclude mobile Internet usage or to limit it to 8.62 hours per month.

Published: December 2022

O presente artigo discute a interpretação e aplicação da legislação na determinação dos limites das Áreas de Preservação Permanente relacionadas ao relevo. O objetivo consistiu em indicar todas as categorias previstas, em duas microbacias hidrográficas, a do Ribeirão João Leite e a do Ribeirão Extrema, mananciais de abastecimento de dois centros urbanos: Goiânia-GO e Barro Alto-GO. Foram mapeadas oito categorias de APP nas duas bacias: faixas de 30m e 50m nos cursos d’água; faixas de lagoas/reservatórios; raio de 50 m nas nascentes; recuo de 100 m nas bordas de tabuleiros; topos de morro; linhas de cumeada e as escarpas. Também se elaborou mapas de uso e ocupação das duas bacias, para cruzamento com as APP. Constatou-se que na bacia do Ribeirão João Leite, apenas 22,23% encontra-se recobertos por remanescentes, e verificam-se o predomínio das pastagens, com 65% da área. No Ribeirão Extrema, 43,62% estão cobertos por remanescentes, e também há predomínio das pastagens, 48,34%. Em relação às APP, no Ribeirão João Leite, correspondem a 18,25% de sua área, já no Ribeirão Extrema, 26,82%, a classe dos topos de morro predomina em ambas. Percebe-se uma discrepância nos padrões de uso e ocupação, no Ribeirão João Leite 62,07% das APP estão sob uso, já o Ribeirão Extrema apresenta 78,2% de preservação das APP. As categorias mais “respeitadas” correspondem as APP “geomorfológicas”, principalmente pela declividade, já as faixas dos cursos d’água e reservatórios são as mais atingidas.

Published: December 2022

A Depressão de Gouveia vem sendo alvo de diversas pesquisas que buscam caracterizar os sedimentos quaternários regionalmente descritos sob a forma de níveis deposicionais aluviais e coluviais. Esta área é também marcada por forte pedogênese, responsável pela homogeneização dos pacotes coluvionares e, conseqüentemente, pela perda dos vestígios da estratificação dos sedimentos quaternários. Este trabalho teve por objetivo contribuir para a identificação e caracterização das descontinuidades estratigráficas tendo por base a análise mineralógica da fração areia de quatro perfis de solo: P1, P2, P3 e P4. Para o ponto P1 foi admitida a ocorrência de uma descontinuidade: entre os horizontes C1 e 2C2, associada à ocorrência de linha de pedra. Para o ponto P2 não foi admitida descontinuidade. Para o ponto P3 foi admitida a ocorrência de descontinuidade entre os horizontes Bi e 2C a partir do aumento da caulinita em profundidade em detrimento da muscovita. Já para o ponto 4 foi admitida descontinuidade entre os horizontes BA e 2Bw1. Em algumas das descontinuidades admitidas a caracterização mineralógica corroborou vestígios previamente identificados a partir da análise morfológica. Não foi possível identificar um padrão de ocorrência entre as descontinuidades estratigráficas e as linhas de pedra registradas nos perfis da área de estudo.

Published: December 2022

Na última década, projetos capazes de articular extensão universitária e empreendedorismo social com a formação crítica de professores em cursos de licenciatura, notadamente, vêm trazendo novas perspectivas para os campos da educação e das políticas de desenvolvimento local. O projeto Geografia em Comunidade, desenvolvido no bairro Cidade Nova (Diamantina-MG) a partir de 2013 por docentes e estudantes do curso de Licenciatura em Geografia da UFVJM, visa a formação de uma geração de empreendedores sociais na educação, com foco na melhoria do ambiente escolar, na aprendizagem colaborativa e no desenvolvimento local. Inicialmente, o presente estudo expõe uma revisão crítica da literatura acerca do desenvolvimento de práticas de extensão universitária e de empreendedorismo social na educação, explorando as possíveis contribuições para a aprendizagem colaborativa no processo de formação de professores. Mais adiante, as principais atividades implementadas pelo Geografia em Comunidade entre 2013 e 2017 são analisadas de maneira reflexiva tendo como pano de fundo o contexto espacial, demográfico e socioeconômico do bairro e da cidade. As atividades do projeto são situadas dentro de um modelo esquemático elaborado pelos autores que sintetizam as possiblidades de integração entre universidade, escola, poder público e setor privado. O trabalho demonstra que o Geografia em Comunidade deve ser tratado como um case de sucesso com enorme potencial para ser replicado ou, também, inspirar outros projetos do gênero.
Aplicação de técnicas de preenchimento de falhas de dados de pluviosidade mensal e anual para o noroeste do estado de Minas Gerais - Brasil
Authors: Jardim Carlos Henrique , Silva Aion Angelu Ferraz
Published: December 2022

A utilização de séries históricas de dados meteorológicos exige a aplicação de técnicas estatísticas para correção de falhas (ausência, erro de registro etc.), podendo comprometer a análise caso não seja implementada. A partir dessa perspectiva, a finalidade deste artigo foi analisar diferentes métodos estatísticos de correção de dados de pluviosidade (Média Aritmética, Ponderação Regional, Regressão Linear Múltipla e Ponderação Regional com Base em Regressões Lineares) e discutir sua aplicação. Foram obtidos dados de chuva diários de sete estações pluviométricas da Agência Nacional de Águas (situadas na porção noroeste do estado de Minas Gerais) entre os anos de 1995/1996 e 2014/2015, cuja validação foi realizada pelo processo de consistência da técnica de dupla massa. Foi utilizada uma estação de testes para correção (Fazenda Conceição) e outras seis de apoio, que totalizaram 1040 registros estimados de precipitação (240 meses e mais 20 anos para cada). A Regressão Linear Múltipla foi a técnica que obteve as melhores estimativas nas escalas anual e mensal para o período de outubro a maio (meses chuvosos), porém não houve a prevalência de uma técnica no período de junho a setembro (meses seco).

Published: December 2022

Apesar da queda no ritmo de crescimento demográfico observado nas últimas décadas do século passado, as periferias metropolitanas no Brasil continuam atraindo expressivos fluxos populacionais. O propósito desse artigo é avaliar o suposto ganho de autossuficiência econômica dos municípios da Periferia Metropolitana de Belo Horizonte, tendo como base os deslocamentos pendulares. Com base nos microdados amostrais dos Censos Demográficos de 1980, 2000 e 2010 foi possível identificar um sensível crescimento no volume de trabalhadores e estudantes que realizam suas atividades na própria periferia metropolitana, ainda que Belo Horizonte tivesse mantido sua centralidade regional. Mesmo que boa parte dessa mão de obra esteja vinculada a setores com menor nível de qualificação ocupacional, parece que o mercado de trabalho local tem ampliado o seu poder de atração e retenção, permitindo que parte da população esteja ocupada no próprio município de residência.

O dados provenientes de Sensoriamento Remoto (SR) quando integrados a Sistemas de Informações Geográficas (SIG) permitem identificar, reduzir e reestruturar diferentes questões ambientais relacionadas ao planejamento urbano. Tratando-se de fenômenos naturais severos, como é o caso das inundações, essas questões podem envolver vidas humanas, bens materiais e infraestruturas decisivas. Nessa conjuntura, o presente trabalho desenvolveu um modelo de análise multicritério de apoio à decisão do tipo fuzzy com pesos de evidências aliado à Análise Hierárquica de Processos (AHP).  As análises e aplicações do trabalho utilizaram dados e métodos de sensoriamento remoto e geoprocessamento para determinar riscos à inundação em áreas do município de Nova Lima na região metropolitana de Belo Horizonte, Minas Gerais. Na construção dos modelos, foram utilizadas diversas variáveis de entrada, tais como: Modelo Digital de Elevação (MDE), Declividade, Uso e Ocupação do Solo, Área de Preservação Hidrográfica Permanente, Isoietas Climáticas, Geologia e Tipo de Solo. A fuzzificação por pesos de evidência foi realizada para identificar regiões aptas e não aptas em relação à inundação para cada variável, produzindo-se mapas individuais valorados de 0 a 1. Na composição do processo, utilizou-se o método AHP na multiplicação dos mapas fuzzificados por meio de notas de especialistas e de pesquisa bibliográfica produzindo-se um mapa crítico com os níveis de susceptibilidade à inundação. A validação dos resultados do estudo foi feita por meio da comparação com dados de referência preexistentes obtidos da Secretaria de Estado de Meio Ambiente e Desenvolvimento Sustentável (SEMAD), da Companhia de Pesquisa de Recursos Minerais (CPRM) e de informações locais. O processo de validação apresentou coerência de 86%, indicando a eficácia da metodologia desenvolvida. A execução simples, o baixo custo e a coerência dos resultados obtidos deixa evidente o caráter inovador  da metodologia. Portanto, a identificação das áreas susceptiveis ao risco à inundação usando a metodologia fuzzy e AHP, mostrou-se importante para identificar áreas que necessitam de maior atenção do poder público e de investimentos em ações de proteção, prevenção e mitigação. Dessa forma, o estudo é uma contribuição para a gestão de riscos e desastres em áreas atingidas por inundação.
Cidade hostil

A exposição diária ao medo da violência e a busca de privacidade têm contribuído para o processo de segregação urbana. Intensificam-se, no Brasil, soluções individuais para problemas coletivos. Pela literatura, observamos que a desertificação do espaço urbano é um dos fatores-chave da percepção da sensação de insegurança, pois o espaço perde a atratividade e pessoas atraem pessoas, o que gera a tão desejada vitalidade urbana. Quando a arquitetura se reveste de formas limitadoras – visuais, físicas e sociais – essa arquitetura é hostil. O objetivo desse artigo é discutir como a arquitetura hostil tem se instituído como elemento ativo na retroalimentação da percepção da sensação de insegurança urbana, na medida em que limita e condiciona a experiência do espaço urbano entre iguais e produz “extramuros”, espaços áridos, impermeáveis, desproporcionais à escala humana. Para pesquisa foi estudado o bairro do Espinheiro, na cidade do Recife, pois foi o bairro que mais verticalizou na cidade dentro do recorte de estudo, sendo modificador do padrão da habitação e da forma de habitar. Percebemos que a arquitetura promovida pelo mercado imobiliário não caminha na direção estabelecer relações que acolham o indivíduo. Cada dia mais edificamos barreira no espaço urbano. Os indivíduos vêm ao longo das últimas décadas buscando uma proteção individualista, o que reflete uma perda de urbanidade, ou seja, as características inerentes da arquitetura levam para uma urbanização privatizada, centrada em homogêneos.

A demanda por informações sociais e demográficas na formulação e disseminação de políticas públicas municipais vem crescendo no país, no âmbito da promoção da parcela da população fragilizada economicamente. O conhecimento do significado, dos limites e potencialidades dos indicadores sociais pode ser de grande utilidade para os diversos agentes e instituições envolvidas na definição de políticas públicas. O objeto deste estudo é a utilização do geoprocessamento na identificação de áreas vulneráveis do município de Belo Horizonte, no campo da atuação das Políticas Públicas Sociais, como uma ferramenta de promoção da igualdade entre os munícipes. Percebe-se que o emprego de técnicas de geoprocessamento pode ser aplicado no mapeamento de áreas onde a falha de interlocução com o poder público estão expostas, incorrendo no que pode ser chamado de riscos sociais, por haver um menor efeito de transformação na sociedade causado pela ausência ou pouca atuação do poder público.

Diferentes métodos de caracterização e avaliação ambiental são aplicados em estudos que tenham, como unidade espacial, as bacias hidrográficas. No intuito de auxiliar a tomada de decisão, voltada ao planejamento, conservação e mitigação de eventuais conflitos, estudos desta natureza valem-se de procedimentos que conciliam uma interpretação apurada do meio físico, podendo combinar-se com os propósitos cartográficos, em aspecto quali-quantitativo. O método Potencial de Uso Conservacionista (PUC) contempla esta premissa e se aplica à análise espacial de bacias hidrográficas, em função dos potenciais de recarga hídrica e de uso agropecuário, bem como da resistência à erosão. Baseado no método multicriterial da Análise Hierárquica de Processos (AHP) de Saaty (1997), o PUC considera a ponderação de valores dados às classes de solos, litologia e declividade e, expressa-se, cartograficamente, por meio da álgebra de mapas e avaliações zonais. Este trabalho objetivou a descrição do método PUC, tendo-o aplicado ao estudo da bacia hidrográfica do Rio Gualaxo do Norte (BHRGN), localizada no estado de Minas Gerais, Brasil. De forma prática, a interpretação da aplicação do método demonstrou que a BHRGN possui, majoritariamente, áreas de médio PUC, em consonância com os atributos físicos distribuídos na área.
