Authors: Kfouri Tanes , Costa Rogério Santos da , Fernandes Renata Goulart
Published: December 2017

O objetivo deste artigo é analisar a sustentabilidade econômico-ambiental da comunidade pesqueira da Praia da Armação – Florianópolis/SC/Brasil, através de levantamento de dados sobre a quantidade de pescadores envolvidos, número e tipo de embarcações, e se o modelo de pesca utilizado na Praia da Armação consegue aliar sustentabilidade econômica e ecologica à localidade. A pesquisa se deu em duas frentes, uma bibliográfica e outra de levantamento de dados primários. A parte bibliográfica contemplará a discussão sobre peixes, tipos de pesca, produtos da pesca, valor do pescado, sustentabilidade econômica e ambiental. A coleta de dados primários foi organizada e realizada em torno de três sujeitos principais: a colônia de pescadores artesanais da praia da Armação em Florianópolis, a comunidade local e os restaurantes que ali se encontram. A maior constatação do trabalho é que esta atividade naquela região não se enquadra no conceito exposto de sustentabilidade econômico-ambiental, merecendo atenção de políticas públicas para que se reverta um quadro que pode resultar em degradação socioambiental no local. Ao final sugere-se ações de políticas publicas e de governança pública para a reversão ou minimização deste quadro.

A aviação comercial favorece o desenvolvimento econômico no país, contudo, pode causar impactos negativos para o meio ambiente e para a comunidade localizada no entorno dos aeroportos. O objetivo geral deste estudo foi analisar os impactos ambientais provocados pelo mercado de aviação civil no Brasil, e quais os procedimentos e programas adotados em busca do desenvolvimento sustentável. Quanto à metodologia, foi realizada uma pesquisa descritiva, de natureza qualitativa, baseada em uma revisão de literatura sobre o tema. A revisão de literatura demonstrou que os principais impactos ambientais negativos provocados foram: o ruído dos aviões (poluição sonora); o impacto das emissões dos motores das aeronaves, ao nível do solo e globalmente; a poluição do solo e de corpos d’água (rios, lagos etc.) devido aos resíduos poluentes, originados pelas atividades realizadas nos aeroportos e intensificação do tráfego de veículos na região dos aeroportos. Quanto às políticas adotadas pelas companhias aéreas em busca do desenvolvimento sustentável, a Boeing e a Embraer entre outras, reuniram esforços e implantaram políticas voltadas à redução das emissões de gases de efeito estufa originados pelas operações de transporte aéreo. Conclui-se que as companhias aéreas que atuam no Brasil, têm reunido esforços no sentido de investir em ações sustentáveis, visando à melhoria da prestação de serviços e segurança dos seus clientes, a segurança no trabalho e a redução de custos através do uso de aeronaves mais leves, com menor consumo energético. A redução dos impactos negativos na aviação civil brasileira passa por ações sustentáveis baseadas em parcerias entre as companhias aéreas atuantes no país e os aeroportos, envolvendo nesse processo a comunidade de seu entorno para a melhoria da qualidade de vida da população local.

Published: December 2017

Este artigo informa sobre os aspectos legais referentes à implantação da apicultura de Apis mellifera na recuperação de solos degradados situados em área de preservação permanente e reserva legal. Assim, este trabalho teve como objetivo verificar se é possível, sob a legislação brasileira viabilizar a exploração da apicultura comercial nestas áreas para geração de recursos, desde que não afetem o meio ambiente. Concluiu-se que a legislação atual não veta a recuperação dessas áreas com a introdução da apicultura, que é considerada atividade de baixo impacto ambiental, face as vantagens auferidas de polinização e usos diversos, inclusive a alimentação humana. Os recursos extras gerados poderão ajudar a convencer o proprietário rural a investir na recuperação, ao mesmo tempo em que preserva o meio ambiente.

A gestão de recursos hídricos está relacionada às políticas públicas, práticas, tecnologias aplicadas na distribuição, uso e conservação da água. O alto custo ambiental resultante da má gestão dos recursos passou a exigir de todos os setores uma rigorosa regulação de atividades e mitigação dos impactos por elas causados. Os impactos negativos aos recursos hídricos geram danos irreversíveis, graves conflitos, sendo a solução nestes casos lenta, extensa e demandando altos investimentos.  Neste cenário, a demanda do turismo, lazer e esporte figuram de forma complementar, entretanto, se as áreas forem observadas pela perspectiva ambiental, estas atividades se tornam representativas, pois são impactadas pelos demais problemas oriundos dos outros setores. Do método, através de levantamento bibliográfico, pesquisa primária, secundária, exploratória, saídas de campo in loco e busca quali e quantitativa, este estudo de caso identificou os usos dos recursos hídricos em 35 municípios que compõem a Bacia Hidrográfica do Rio das Antas, bacias contíguas e afluentes do Rio Peperi-Guaçu / Região Hidrográfica 01, no Oeste de Santa Catarina, observou suas potencialidades turísticas, esportivas, recreativas e culturais, avaliou os impactos de cada atividade. Estas sofrem diretamente com escassez e com a falta de qualidade dos recursos hídricos. Ainda que neste estudo de caso os resultados representem baixos impactos aos recursos hídricos por conta do baixo grau de desenvolvimento turístico da região, as atividades devem observar e mensurar seus impactos atuais, a fim mitigar os impactos ambientais, reduzir conflitos dos usos múltiplos das águas, elaborar o planejamento e ações efetivas de desenvolvimento sustentável.

Published: December 2017

Atualmente, apesar de todo o processo de globalização no mundo, as tendências de consumo apontam para a valorização de produtos regionais, de pequenos e médios produtores que trabalhem com controle de qualidade em toda a cadeia produtiva e além disso se unam em clusters, que pode ser entendido como uma aglomeração geográfica de empresas, como estratégia de desenvolvimento e fortalecimento econômico de uma região. Estas tendências, vem ao encontro do comportamento de um consumidor cada vez mais informado e consciente quanto às suas escolhas e também se aproxima do conceito de regionalização, que confere credibilidade aos produtos. A Denominação de Origem (D.O) representa uma das espécies da Indicação Geográfica (I.G), e é o foco da pesquisa bibliográfica, documental e descritiva deste artigo, considerando a trajetória histórica, legislações e órgãos responsáveis pela concessão do reconhecimento, bem como, no contexto atual, qual a importância do selo nos produtos catarinenses e como ele pode representar uma vantagem competitiva aos mesmos, considerando locais que já estejam com o processo em andamento para o reconhecimento como aqueles com potencial para a concessão.

O setor de saúde tem sido instado a participar ativamente, seja pela sua atuação tradicional no cuidado a populações atingidas por riscos ambientais, seja pela valorização das ações de promoção. Dentro da Atenção Básica (AB) o Ministério da Saúde possui como principal estratégia para remodelar o modelo de assistência à saúde, o programa “Estratégia Saúde da Família” (ESF). O presente estudo teve por objetivos realizar o diagnóstico ambiental do município de São José do Sul/RS, Brasil, descrever o processo de promoção da Saúde Ambiental no ESF e problematizar o envolvimento do profissional de meio ambiente na Atenção Primária Ambiental (APRIMA). Aplicaram-se questionários junto aos agentes comunitários de saúde (ACS) e comunidade, e entrevistas com os profissionais da unidade básica de saúde (UBS) e gestores municipais. A caracterização ambiental mostrou que o município apresenta problemas relacionados com as práticas do campo, como o uso de agrotóxicos, incinerações não autorizadas, vetores e desmatamento. Além de problemas urbanos como a falta de saneamento básico. As entrevistas com os gestores e profissionais de saúde mostraram que o conceito de Saúde Ambiental não está, ainda, inserido no cotidiano, denotando tratar-se de um campo pouco explorado. Este estudo elenca uma série de ações que poderiam ser tomadas em conjunto com o profissional da Engenharia Ambiental, visando o enfrentamento das questões ambientais do município de São José do Sul/RS como: capacitação dos ACS na temática, o uso de agrotóxicos, suinocultura, saneamento básico, melhorias sanitárias domésticas (MSD) e oficinas municipais de saúde (OMS), resíduos orgânicos e abastecimento por poços artesianos.

Published: December 2017

A observação de aves ou birdwatching é uma atividade pouco executada no Brasil e envolve registros visuais ou auditivos de aves. Em Unidades de Conservação pode servir como ferramenta para educação e conscientização ambiental além de atrair turistas. Esse estudo tem por objetivo avaliar o potencial de implantação de birdwatching no Parque Natural Municipal do Atalaia (PNMA) em Itajaí – SC. O levantamento das espécies de aves ocorrentes no Parque foi adquirido a partir de trabalhos acadêmicos, guia de aves do Parque do Atalaia, site WikiAves e através dos registros de um praticante local de birdwatching. Foram aplicados questionários semi estruturados aos visitantes e questionários não estruturados aos funcionários para avaliar a estrutura e possibilidade de implantação da atividade. Foram registradas 145 espécies de aves pertencentes a 43 famílias no PNMA, sendo Thraupidae a família mais representativa, com 24 exemplares. Dos 50 visitantes entrevistados, 85% possuem interesse na atividade de observação de aves. A estrutura do Parque apresenta-se adequada para a prática, com possibilidade de passeios com guias especializados, presença de mirantes e boa sinalização. Existe interesse tanto do público quanto dos funcionários na implantação da atividade de birdwatching no local, entretanto, é necessário adequar-se aos horários da prática e realizar melhorias no acesso ao Parque. Contudo, os gastos com infraestrutura serão ínfimos frente às possibilidades de retorno econômico e trabalho advindos do aumento de circulação de turistas birders na região.

Published: December 2017

Domestic Violence against women is very common in both developing and developed countries and is a complex and multi-dimensional phenomenon. However, global developments have yet to be systematically assimilated into theories around violence against women. This study seeks to examine the associations between domestic violence against women household headship and women empowerment in Nigeria. The study used data from the 2013 Nigeria Demographic and Health Survey (DHS). Ordinary least squares (OLS) regression method was used to assess the association among the study variables. The analysis showed that domestic violence is usually more where there are women-household headships in case of Nigeria changing the general idea of having less domestic violence in women headed households. There should be strict and effective laws against domestic violence. Men or women whoever is domestically violating another woman should have to deal with legal consequences; otherwise, this trend of domestically violating women will go on forever.

Contextualizing the Identity Development of Preservice Elementary Mathematics Teachers in Methods Courses and Mentor Teacher Support
Authors: Kang Hyun Jung , Battey Dan
Published: December 2017

Drawing on a situative perspective, this study explores how preservice elementary teachers develop themselves as teachers of mathematics and critical experiences in their identity development, in particular, from teacher education coursework through their student teaching experiences. Through two cases, this study reveals that mentor relationships were critical in shaping preservice teachers’ identities as mathematics teachers and in building their initial mathematics teaching practices. Findings suggest that successful mentoring is necessary, and this generally requires sharing common goals, receiving feedback, and having opportunities to practice knowledge, skills, and identities on the part of beginning teachers. This study adds to the field of teacher education research by focusing on prospective teachers’ identity constructions in relation to their communities of practice, and also by emphasizing the role of mentors in preservice teachers’ identity development.

Published: December 2017

A etiologia mais provável da disfunção temporomandibular (DTM) é multifatorial. Esse fato torna complexo o seu diagnóstico e tratamento para a área de Odontologia. Um dos componentes importantes na etiologia e perpetuação da DTM, ainda pouco explorado no tratamento dessa síndrome, é o psicológico. Sendo assim, este artigo teve como objetivo apresentar revisão sistematizada da literatura enfocando a integração da DTM e psicologia. Foi realizado um levantamento nas bases de dados Pubmed e Scielo no período de 2010 a 2017 utilizando como critério de inclusão: artigos publicados na língua inglesa ou portuguesa com os descritores psicologia e síndrome da articulação temporomandibular ou psicoterapia e articulação temporomandibular. Foram excluídos os artigos onde o componente psicológico nos casos de DTM foi apenas citado e não avaliado e artigos de revisão de literatura. A busca selecionou 23 artigos, dos quais 17 citavam a psicologia como etiologia, relacionado com a qualidade de vida e somente 4 propuseram terapias psicológicas para o tratamento da DTM, sendo que 1 associou a psicoterapia com o relaxamento. Os resultados obtidos enfatizaram a importância da integração entre as áreas do saber para proporcionar atendimento integral aos portadores desta disfunção. Apesar disso, a literatura disponível abordando terapias psicológicas no tratamento da DTM é escassa justificando a necessidade de estudos nessa área.Descritores: Síndrome da Disfunção da Articulação Temporomandibular, Odontologia, Psicoterapia.

Use of Molecular Markers to Compare Escherichia coli Transport with Traditional Groundwater Tracers in Epikarst
Authors: Bandy Ashley , Cook Kimberly , Fryar Alan E. , Polk Jason
Published: December 2017

Bacterial contamination of karst aquifers is a global concern as water quality deteriorates in the face of decreasing water security. Traditional abiotic groundwater tracers, which do not exhibit surface properties similar to bacteria, may not be good proxies for risk assessment of bacterial transport in karst environments. This study examined the transport and attenuation of two isolates of Escherichia coli in relation to traditional groundwater tracers (rhodamine WT dye and 1‐μm‐diam. latex microspheres) through ∼30 m of epikarst in western Kentucky. Differential movement of the four tracers was observed, with tracer behavior dependent on flow conditions. Dye arrived at the sampling site prior to particulates. Molecular biology techniques successfully detected bacteria in the cave and showed attenuation was greater for a bacterial isolate with high attachment efficiency compared with an isolate known to have low attachment efficiency. Microspheres were first detected simultaneously with the low‐attachment isolate but attained maximum concentrations during increases in discharge >11 d post‐injection. Bacteria were remobilized by storm events >60 d after injection, illustrating the storage capacity of epikarst with regard to potential contaminants. The two bacterial strains were not transported at the same rate within the epikarst, showing breakthroughs during differing storm events and illustrating the importance of cell surface chemistry in the prediction of microorganism movement. Moreover, this study has shown that molecular analysis can be successfully used to target, quantify, and track introduced microbial tracers in karst terrains.

Core Ideas

Reference genes are selected based on the assumption of temporal and spatial expression stability and on their widespread use in model species. They are often used without validation in the studied species. For barley (Hordeum vulgare L.), previous reference gene validation studies have been limited by the number of tissues, cultivars, and/or reference gene candidates assayed. Publically available bioinformatic resources are now available that enable efficient assessment of much larger numbers of candidate genes than is possible with empirical approaches. Expression sequence tag profile viewer data from the UniGene library were used to predict the expression stability of 655 barley genes. The expression profiles of 20 gene candidates predicted to be stable across tissue types were evaluated in eight tissues of the cultivar ‘Conlon’ by real‐time quantitative polymerase chain reaction. The five most stable genes were then tested in the barley cultivars ‘Golden Promise’ and ‘Harrington’ and (to test potential applicability to other Poaceae species) in the oat (Avena sativa L.) cultivar ‘Hifi’. The traditional reference gene actin and the candidate genes elongation factor EF‐2 and malate dehydrogenase demonstrated the most stable expression. The predictive capacity of bioinformatics to identify suitable reference genes was demonstrated. Four genes with better stability than all except one traditionally used reference gene were discovered.

Core Ideas

A 3‐yr hillslope study presents DOC, DOC, TP, and DRP losses from several olive orchards.

Losses of DOC and TOC were higher than those measured in other agricultural systems.

Losses of TP were at the high‐end range of losses measured in agricultural systems.

Temporary cover crops in lanes can reduce TOC and TP losses through reduced sediment losses.

Cover crops did not significantly reduce DOC and DRP in runoff compared with conventional tillage.

Dissolved organic C (DOC) and dissolved reactive P (DRP) in runoff and total organic C (TOC) and total P (TP) in sediment were measured in three olive (Olea europaeaL.) orchards, during a 3‐yr runoff plot experiment under two soil management systems (temporary cover crop in lanes [CC]; conventional tillage [CT]). Losses of DOC (7.8–13.6 kg ha−1yr−1) were equivalent and losses of TOC (101–432 kg ha−1yr−1) were higher than those measured in other agricultural systems, so both sources of organic C, dissolved and in sediment, should not be neglected when accounting fluxes to water bodies in the region and soil organic C (SOC) balances at the hillslope scale in olive orchards. Losses of DRP (0.03–0.21 kg ha−1yr−1) were in the lower to medium range, while losses of TP (2–39 kg ha−1yr−1) were in the higher range than those reported from agricultural areas. The average annual concentration of DOC in runoff was similar for both systems (20.9–9.1 vs. 21.4–8.7 mL L−1for CC and CT, respectively) and also for DRP (0.45–0.02 vs. 0.20–0.02 mg L−1for CC and CT, respectively). Concentrations of TOC and TP were higher under CC, but under CC the TOC and TP fluxes were lower because of reduced sediment losses. To achieve a large reduction in TP and TOC, CC management should provide early ground cover beginning in early fall, the start of the rainy season. A conceptual model of TOC and TP losses was developed to estimate the impact of different cover crop soil conservation strategies.

Core Ideas

This special section is a snapshot of current work and understanding of lateral surface transport processes.

The particular focus is on soil erosion.

Soil erosion is a very large and very important topic.

It must be addressed from both practical and rigorous scientific angles.

Erosion can cause serious agricultural and environmental hazards. It can generate severe damage to the landscape, lead to significant loss of agricultural land and consequently to a reduction in agricultural productivity, induce surface water pollution due to the transport of sediments and suspended material to waterways and rivers, and alter the operation of hydraulic structures due to clogging of channels and sediment loading in reservoirs, estuaries, and oceans. The loss of soil due to erosion will also diminish its capacity to store water, which will not only negatively affect plant growth but might also increase the risk of flooding. Furthermore, erosion plays a significant role in the biogeochemical cycles of carbon, nitrogen, and phosphorus as it redistributes significant amounts of these elements across the surface of the Earth. This special section focuses on many of these aspects and gathers studies presenting valuable experimental and monitoring data, recent relevant technologies and measuring tools, and new modeling approaches that allow a better estimate of the intensity of the degradation processes and a better assessment of their multiscale nature and their coupling with biogeochemical processes as well as soil functioning.

The paper aims to review the dominating literature and recent findings on organizational changes and sustainability strategy. The studies in the spheres of strategic management and organizational theories have common conceptual base but different approaches to the key definitions identification. Sustainability age had transformed the perception of the best practices in markets, the winners in 80-ties were focused on costs leadership, today it is urgent to offer differentiated product that is sustainability-oriented. The studies in sphere of strategic management, organizational theories and social development theories were analyzed to accumulate the knowledge about the sources and content of organizational changes towards sustainability. Two types of barriers to transformation towards sustainability were analyzed through data comparison and previous findings accumulation and generalization. General recommendations for sustainable innovations creation are offered.

Bacteriophages infecting Bacteroides fragilis GB-124 have been described as potential markers of human fecal contamination in water sources. The aim of this study was to evaluate the occurrence of GB-124 phages in raw sewage, secondary effluents and reclaimed water of the São Paulo city using a low-cost microbial source tracking method. Samples were collected monthly from April 2015 to March 2016 in four municipal wastewater treatment plants that operate with activated sludge processes followed by different tertiary treatments (sand-anthracite filtration, membrane bioreactor/reverse osmosis) and final chlorination. GB-124 phages were detected in 100% of the raw sewage samples, with viral loads varying from 7.5 × 103 to 1.32 × 106 PFU/L. Virus removal efficiency in activated sludge processes ranged from 1.89 to 2.31 log10. Frequencies of phage detection were lower in reclaimed water samples (0–22.2%). The results indicated that GB-124 phage could be a complementary low-cost viral marker for the detection of human fecal pollution in waters impacted with urban sewage in this region. However, the datasets of tertiary effluents resulted in several samples with concentrations below the detection limit (DL ≤1 PFU/mL) suggesting the need to obtain analytical methods with lower DL for greater accuracy of negative results.

Published: December 2017

The effectiveness of green tea (Camellia sinensis) and pomegranate (Punica granatum) extracts for the production of iron nanoparticles and their application for color removal from a textile industry wastewater was investigated. Polyphenols in extracts act as reducing agents for iron ions in aqueous solutions, forming iron nanoparticles. Pomegranate extract was found to have almost a 10-fold higher polyphenolic content than the same amount of green tea extract on a mass basis. However, the size of the synthesized nanoparticles did not show a correlation with the polyphenolic content. 100 ppm and 300 ppm of iron nanoparticles were evaluated in terms of color removal efficiency from a real textile wastewater sample. 300 ppm of pomegranate nanoscale zero-valent iron particles showed more than 95% color removal and almost 80% dissolved organic carbon removal. The degradation mechanisms are is considered to be adsorption and precipitation to a major extent, and mineralization to a minor extent.

Published: December 2017

The objective of this study was to determine how macrophytes commonly used in treatment wetlands (TWs) respond to water with low pollutant concentration. We measured pollutant removal efficiency and compared growth and nutrient uptake of five macrophytes in demonstration scale units (volume >40 m3) irrigated by water with pollutant concentrations representative of average urban stormwater quality. All species showed a strong productivity gradient along the beds, starting with high biomass – high density near the inlet, then decreasing progressively with distance. Cyperus was by far the most productive species. Phragmites and Thalia had higher biomass in the first few metres of the beds than Typha and Arundo. In terms of pollutant removal, decreasing plant growth may be interpreted as indicative of high efficiency when caused by nutrient depletion. Differences in aboveground biomass between species did not translate into measurable differences in removal efficiency at the outlet. Although Phragmites australis is the species most commonly used in TWs, under the low nutrient load, Cyperus had twice its biomass, and higher N and P uptake. These results highlight the importance of considering wastewater characteristics when selecting macrophyte species for TWs.
