Pre-Service Teachers’ Experience of Learning about Sustainability in Technology Education in South Africa
Authors: Singh-Pillay Asheena
Published: January 2023

There have been many calls for the integration of Education for Sustainable development in the training of pre-service teachers so that they can develop sustainability action competence to address sustainability issues now and in the future in their communities. This qualitative pilot project sought to explore pre-service technology teachers’ (PSTTs) experiences of learning about sustainability in the processing of the polymers module, when they were engaged in community-based assessment tasks. Data was collated from 25 PSTTs enrolled for the processing of the polymers module using reflective diaries and semi-structured interviews. Thematic analysis revealed that PSTTs had three key experiences of learning about sustainability, making a difference, learning as hands-on, minds-on, and hearts-on and sustainable pedagogies. At a theoretical level, the findings highlight the value of adopting an ESD lens and experiential learning approach to infuse learning about sustainability when teaching technology education. Further, the findings indicate that if PSTTs are challenged to participate actively in sustainability issues in their communities, they make informed choices about their role in society as future teachers, the pedagogies they plan to adopt, and the kinds of learning they strive to promote in learners.
Drone Use in On-Farm Environmental Compliance: An Investigation of Regulators’ Perspectives
Authors: Westbrooke Victoria , Lucock Xiaomeng , Greenhalgh Isobel
Published: January 2023

Freshwater resources around the world are under increasing pressure from agricultural activities. As a result, regulatory frameworks around on-farm environmental compliance have become more complex. Consequently, farm plans which have been used in New Zealand to identify risks to and develop mitigation strategies for freshwater quality can be time consuming and costly to develop and monitor. Using semi-structured interviews, this study investigated the views of the regulators working in environmental policy and implementation on the use of drones to increase the efficiency of on-farm environmental compliance. Results show that drones can improve process robustness by providing an aerial view, and that they are quicker and safer to use on steeper contoured farms. However, there is confusion around the permissions required in order to capture footage, its ownership and storage, and who has access rights to the footage. This ambiguity in the implementation of environmental regulations can lead to uncertainty on the part of policy implementors around how to integrate drones in on-farm environmental compliance. In addition, positive relationships between farmers and compliance officers are needed in order for the benefits of drone use to be realised for on-farm environmental compliance purposes.

Authors: Qu Xiaoyu , Qin Xutian , Wang Xiaopeng
Published: January 2023

With the continuous advancement of digital globalization, enterprises need to seek development opportunities in the context of diversification and resource shortage. Frugal innovation provides a new way for enterprises to realize social value and create a win-win situation. Based on 113 enterprises’ survey data, fuzzy set qualitative comparative analysis (fsQCA) and necessary condition analysis (NCA) are used to explore the multiple concurrency factors and causality mechanisms of digital transformation, organizational resilience, learning from failure and design thinking for frugal innovation. It is found that: (1) Digital transformation, organizational resilience, internal learning from failure, external learning from failure and design thinking cannot effectively stimulate frugal innovation alone, and linkage matching of multiple antecedents is needed to promote frugal innovation. (2) There are three paths to producing high frugal innovation, namely, external learning from failure and design thinking driving under digital transformation learning from failure driving under design thinking guidance, organizational resilience driving under digital transformation. (3) There are two paths to produce non-high frugal innovation, which are asymmetrical with high frugal innovation path. Our results are helpful for the study of digital transformation and frugal innovation at the enterprise level. In addition, our research results also provide practical solutions and a theoretical basis for enterprises to carry out frugal innovation activities under the new economic normal.

Published: January 2023

A novel method was developed and optimized for the fast-screening analysis of additives in electronics and plastic consumer products using atmospheric pressure matrix-assisted laser desorption ionization (AP-MALDI) coupled with a high-resolution quadrupole time-of-flight (qTOF) mass spectrometer (MS). To simplify sample preparation and increase sample throughput, an innovative 48 well graphene nanoplatelets (GNP) doped AP-MALDI target plate was developed. The GNP incorporated in the target plate fulfilled the role of the MALDI matrix and, therefore, sample extracts could be directly transferred to the AP-MALDI 48 well target plate and analyzed without a subsequent matrix addition. The homogeneously dispersed and immobilized GNP target plates also provided increased signal intensity and reproducibility. Furthermore, analytical standards of various plastic additives and plastic products with known concentrations of additives were studied to assess the AP-MALDI ionization mechanisms and method capability. The analysis time was 15 s per measurement using an automated sequence. The GNP-doped target plates exhibited high desorption/ionization of low molecular weight molecules (<1000 Da) and can be used in both positive and negative ionization modes. The AP-MALDI-qTOF-MS method was applied to screen for additives in various electronics and plastic consumer products. Suspect screening was performed using a database containing 1366 compounds. A total of 56 additives including antioxidants, flame retardants, plasticizers, UV-stabilizers, and UV-filters were identified (confidence level 4). Identification of certain plastic additives in plastic children’s toys may indicate that they are recycled from waste electronic and electronic equipment (WEEE).
The Effect of Short-Term Upwelling Events on Fish Assemblages at the South-Eastern Coast of the Baltic Sea

Published: January 2023

Multiple stressors, such as overfishing, pollution, climate change, biological invasions etc., are affecting fish communities, and thus can have versatile effects on marine ecosystems and socio-economic activities as well. Understanding the changes in the fish community structure is ecologically and economically important, yet a very complex issue, requiring comprehensive analysis of multiple factors. The role of regional oceanographic variability, namely, coastal upwelling, is often neglected when it comes to the analysis of fish assemblages. In this perspective, we were aiming, for the first time in the Baltic Sea, to assess the upwelling influence on fish communities and fish community-based ecological indices used under Marine Strategy Framework Directive. The study covered a long-term period (2000–2019) for upwelling identified by satellite data analysis and fish gillnet surveys, performed in three distinct locations in the coastal waters of the SE Baltic Sea. Overall, our study revealed that temporal dynamics of fish abundance and community composition were associated with the presence of coastal upwelling. The study outcomes suggest that the fish community was more diverse and a higher number of some fish species was observed before upwelling. During upwelling, there was more evident dominance of 1–2 main marine fish species. Through the changes in fish abundance and species composition upwelling was also responsible for the changes in fish community structure-based indices for marine environment status, i.e., in the majority of the cases a decrease in Trophic, Piscivorous Fish, and Diversity indices were observed. Our study demonstrates that upwelling can affect both, the quantitative and qualitative characteristics of coastal fish communities, therefore, it is important to consider this when predicting shifts in the distribution of fish stocks or assessing environmental status indicators, especially under changing climate. We believe that our approach adds novel information to the study of coastal ecosystems of the Baltic Sea and is important for better management of socio-economic activities in the coastal zone.
Green Zinc Oxide (ZnO) Nanoparticle Synthesis Using Mangrove Leaf Extract from Avicenna marina: Properties and Application for the Removal of Toxic Metal Ions (Cd2+ and Pb2+)
Authors: Al-Mur Bandar A.
Published: January 2023

This work used a variety of experimental studies to explore the elimination of cadmium and lead ions from aqueous solutions using a novel method for the biosynthesis of nanoparticles of zinc oxide sorbents (ZnO-NPs) from mangrove leaf extract. The influences of important factors affecting the adsorption technique were determined, including the pH value, contact duration, the initial concentration of metal ions, nano-adsorbent dose, different temperatures, and interfering ions. To confirm the formation of synthesized ZnO NPs and validate the properties of green-synthesized sorbents, a variety of analytical methods were used, including UV–vis spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The results showed that the average diameter of the ZnO-NPs was approximately 29.1 nm (spherical at the nano-size regime). The adsorption reaction rate was examined by comparing pseudo-second order against pseudo-first order templates. From the observed records, the adsorption reaction of Cd2+ and Pb2+ on the ZnO-NPs fitted well with the pseudo-second order template. Freundlich, Langmuir, Dubinin–Radushkevich, and Tempkin equilibrium isotherm models were used to evaluate the sorption of Cd2+ and Pb2+ onto the sorbent material. Based on the parameters extracted from each model, as well as the model-fitting values, the preferential isotherms for Pb2+ and Cd2+ ion adsorption on ZnO-NPs were the Dubinin–Radushkevich and Langmuir models, respectively. ZnO-NPs have the potential to be used as an effective and promising adsorbent material for eliminating metal ions from water solutions.

Published: January 2023

The impacts of land use/cover changes (LUCCs) on groundwater resources are a global issue. The Shiyang River Basin of China is a typical, ecologically fragile area. Focusing on the Wuwei sub-basin of the central plain, this study analyzed typical remote sensing image data for 17 specific dates since 1970. Before the Comprehensive Treatment Program in 2007, the area of natural oases decreased at a rate of 16.25 km2/year, while the area of farmland expanded at a rate of 13.85 km2/year. The farmland expansion preferentially occurred in low-vegetation-coverage oases, where the groundwater depth increased from 4 to 20 m. The consumption of groundwater increased from 7319.5 × 104 m3/year to 12,943.2 × 104 m3/year. During the period 2008–2018, the areas of both the natural oases and farmland decreased at rates of 2.57 km2/year and 8.99 km2/year, respectively. The groundwater level rose significantly in the south and west, as well as near the main river channel. Groundwater consumption has been restored to 7270.4 × 104 m3/year. Only 0.12 km2 of every 1.17 km2 of the original natural oases were restored through the natural farmland–natural oases conversion process. Groundwater depth increased significantly with the continuous expansion of farmland. Since the farmland area was effectively controlled, the trend of groundwater-level decline was significantly improved. These findings provide scientific support for the ecological restoration and reconstruction of oases, as well as an efficient and balanced development of river basin water resources.

Published: January 2023

Considering the increase in the amount of sewage sludge as a result of the development of urbanization, and the pollution of the environment through the storage of this sludge, the objective of this paper is to analyze the effects of the action of different doses of urban sewage sludge as a fertilizer for agricultural soil. Starting from the legislative recommendations regarding the use of urban sewage sludge in agriculture, we analyzed the sludge resulting from the sewage treatment plant in the Municipality of Alexandria, Romania. This sewage treatment plant, with two technological lines of water and sludge treatment, produces urban sewage sludge without pathogenic bacteria. We highlighted that by applying sewage sludge doses of 15 t/ha and 25 t/ha to agricultural soils, on which we planted soybean and wheat crops. We obtained high yields, and the concentration of heavy metals in the roots, stems and grains of soybean and wheat crops did not exceed the maximum standard limits allowed. Having a high content of organic matter and nutrients important for plants such as nitrogen, ammonium, potassium and zinc, sewage sludge has improved the fertility, physical, chemical and biological properties of the soil, and is able to be used as a fertilizer for degraded soils.

Des jeunes femmes face aux discriminations sociales
Authors: Sotteau-Leomant Nicole , Leomant Christian
Published: January 2023

Les itinéraires de vie de jeunes femmes résidant dans un bassin d’emploi fortement touché par les restructurations industrielles montrent comment la discrimination de genre s’enchevêtre et se cumule avec d’autres formes de discrimination, voire d’exclusion, notamment par rapport au travail salarié. Ils rendent compte de la violence sociale qui leur est faite parce qu’elles sont femmes d’abord, parce qu’elles sont jeunes aussi, et puis, selon chacune d’elles, parce qu’elles sont mères, parce qu’elles résident dans telle ou telle ville stigmatisée, parce qu’elles portent, pour certaines, un nom qui sonne l’immigration maghrébine ou africaine. Cette violence est une atteinte à ce qui constitue cette identité sexuée qu’elles affirment et qui sous-tend leurs pratiques de résistance et leurs initiatives pour obtenir les conditions nécessaires à une vie hors de la précarité et les droits permettant l’exercice de la citoyenneté.
Femmes au chômage : entre révolte et résistance
Authors: Appay Béatrice
Published: January 2023

La précarisation atomise, divise, segmente, déstructure les solidarités. La mise à mal des liens familiaux et des collectifs de travail, le retrait syndical en sont des exemples frappants. De là, à associer précarisation et individualisme, il n’y a qu’un pas. Pourtant, l’ampleur et l’intensité des mouvements sociaux de 1995, le mouvement des chômeurs ainsi que leur soutien populaire, cadrent mal avec cette idée. L’hypothèse est donc que la précarisation sociale, en tant que processus structurel de fragmentation, institutionnalise l’instabilité mais engendre aussi des comportements de résistance et solidarité, où les femmes tiennent une place importante. Trois récits de vie de femmes frappées par le chômage vont aider à comprendre ce paradoxe et permettre d’étayer une autre hypothèse : la précarisation sociale, en se généralisant et en s’approfondissant, génère aussi une condition commune dont la conscience individuelle et collective commence à apparaître.

Pagamentos por serviços ambientais (PSA) x novo código florestal: uma análise no Estado da Paraíba
Authors: Da Silva Santos Vanessa Érica , Fontgalland Isabel Lausanne
Published: January 2023

A Lei n° 14.119 que institui no Brasil a Política Nacional de Pagamento por Serviços Ambientais (PSA) foi sancionada em 2021. O PSA objetiva estimular a recuperação e a manutenção do meio ambiente, por meio de transferências financeiras, vantagens tributárias ou outros tipos de compensação ao protetor/recebedor por ações que resultem na adição ou manutenção de serviços ecossistêmicos. Logo, o presente estudo tem o objetivo de avaliar a aplicabilidade do instrumento econômico de PSA com um enfoque para o Estado da Paraíba com a Lei Estadual 10.165/2013 e realizar um paralelo com o Código Florestal. Para tanto, utilizou-se a revisão bibliográfica como metodologia, usando artigos, livros e teses atuais, no cenário de direito ambiental e relacionada à análise da Lei de PSA. Nesse sentido, foi possível verificar que a Lei 14.119 tem um papel de estimular a sociedade de maneira a geral, a conservar e preservar o meio ambiente proporcionando uma melhor qualidade de vida para o presente e para as futuras gerações, no entanto, sobretudo no Estado da Paraíba é necessário uma normativa mais esclarecedoras de alguns pontos, como por exemplo, a remuneração a ser feita na modalidade dos Pagamentos por Serviços Ambientais.

O estudo é uma revisão da literatura e tem por objetivo apresentar que o gerenciamento de resíduos de serviço de saúde na cidade de Campina Grande está ligado às estratégias de mitigação de riscos ao meio ambiente. As fases do gerenciamento têm como sugestão amenizar os acidentes de manipulação e promover uma visão positiva de que o equilíbrio ambiental é essencial para a qualidade dos hospitais urbanos. Foram utilizados doze artigos e a análise das publicações selecionadas permitiu a identificação de duas categorias temáticas: a análise do gerenciamento dos resíduos dos hospitais e o manejo/classificação dos referidos resíduos, sendo de cunho metodológico bibliográfico e informativo. O objetivo geral apontou a oportunização da legislação da RSS n. 222 à partir da PNRS 2017. Constatou-se a necessidade de se investir em treinamento para os gestores responsáveis pelo gerenciamento dos resíduos de serviço de saúde, para garantir a implementação de procedimentos adequados. Foi ainda observado que em algumas das etapas do manejo dos RSS, muitos dos processos operacionais recomendados ficavam capengas, e também se verificou que o conhecimento sobre o manejo do RSS, pelas diferentes categorias profissionais, é de traçado limitado ou sem nenhuma informação.

El modelo de simulación se basa en el balance másico de los distintos minerales participantes del proceso, con principal atención en los parámetros de operación como lo son mineralogía y leyes de alimentación, tiempos de residencia, fracciones de mineral flotable, medianamente flotable y no flotable con sus respectivas constantes de cinéticas.

Como resultado de las simulaciones que evalúan distintos circuitos, se obtuvieron resultados de ley de cobre en el concentrado de 28,6% y en las colas de un 0,15%, con porcentaje de recuperación de cobre de un 86,5% para un circuito que consta de dos etapas rougher, dos etapas cleaner y dos etapas scavenger.

El modelo permitió determinar el efecto del cambio en el contenido de FeS2 y de los tiempos de residencia en las leyes de concentrado y recuperación de Cu.

Las subcuencas de los ríos Apulco y Tecuantepec son un ecosistema en gran medida valorado tanto para los residentes locales como para los visitantes. Durante los últimos años las consecuencias de la sobreexplotación de los recursos naturales y la contaminación que enfrentan en la zona han provocado la necesidad de acciones y políticas estrictas para la protección tanto de los recursos hídricos como a la biodiversidad, entre otros. Dado que el río ha sido atractivo para las poblaciones humanas, además de proyectos de hidroeléctricas SEMARNAT (2016), por su alta disponibilidad además de que, no ha existido una difusión de conocimientos y tecnologías de producción apropiados para el tipo de ecosistemas presentes en la zona; acompañado por una estructura institucional y administrativa débil que, ha eliminado apoyos e incentivado el uso de agroquímicos en detrimento del suelo, ríos y de quienes aplican y consumen esos productos, generando impactos ambientales significativos, estos mismos demuestran su desesperación con planes de acción inmediatos para el aprovechamiento sustentable de los recursos naturales y medidas de conservación. Por lo que el objetivo de la investigación es hacer la caracterización fisiográfica las subcuencas de los ríos Apulco y Zempoala, cuenca alta río Tecolutla, esta se encuentra ubicada en la Sierra Norte del Puebla.

O mastocitoma cutâneo (MCT) é uma neoplasia de células redondas caracterizada pela proliferação de mastócitos e possui uma grande variação de potencial metastático. O presente estudo teve como objetivo analisar a frequência de MCT cutâneo canino quanto à raça, sexo, idade, localização anatômica e grau histológico. Os dados foram obtidos dos registros dos casos diagnosticados entre 2014 e 2018 na cidade de Niterói - RJ. Os animais mais acometidos foram os sem raça definda (SRD) seguidos da raça Boxer e Labrador. Os locais mais acometidos foram membros, região anogenital e abdome. O MCT cutâneo canino é mais frequente no grau I, na população canina mais velha e nos animais sem raça definida.

A Educação Ambiental na Educação Básica almeja dar início a um esboço de alfabetização científica na infância/adolescência, de maneira lúdica e de forma atrativa, contextualizando o que inferimos como meio ambiente e termos correlatos. Como professoras, sempre nos preocupamos em utilizar distintos recursos didático-pedagógicos em sala de aula, dentre estes, os livros infantojuvenis, com o cuidado de averiguarmos suas proposições e discursos, bem como a correção de seus enunciados. Nossos alunos, num quadro geral, frequentaram escolas públicas com pouca infraestrutura e apresentam problemas conceituais de ecologia e meio ambiente. Diante das dificuldades de compreensão de conceitos como Meio Ambiente, Educação Ambiental e percepção ambiental, e a vivência pessoal das docentes, as professoras pensaram em elaborar livros infantojuvenis que possibilitassem a percepção do meio ambiente, a funcionabilidade e a integralidade dos seres vivos com o meio ambiente. Mostrando que todos possuem papéis importantes para a manutenção da vida no planeta Terra. Procurando trabalhar os aspectos cognitivos, em uma linguagem lúdica e reflexiva sobre a alfabetização Ecológica, de acordo com Capra Fritjof, foram elaborados os seguintes livros: “Vovó mora num Vulcão”, “O Boto Cor-de-Rosa que não é mais Rosa”, “Minhoca Milu”, “Abelhas em Fuga”, “Abelha Zung-Zung em: uma Colmeia no Apartamento?!”. A ecoalfabetização pode acontecer em todas as idades, afinal o aprendizado faz parte da vida do ser humano, mas é na infância que o desenvolvimento da percepção ambiental da funcionabilidade da natureza deve ser introduzido, ensinando os conceitos dos ecossistemas e permitindo ao longo da vida  ampliar sua visão ecológica de cuidado e preservação.

A onça-parda (Puma concolor) é a segunda maior espécie de felídeo no Brasil, pode ser encontrada em algumas regiões da América do Norte e distribuída amplamente em toda a América do Sul. São animais de hábitos solitários, terrestres e predominantemente noturnos. Este estudo retrata a descrição anatômica osteológica e as estruturas ósseas de uma onça-parda (Suçuarana), com informações pouco descritas na literatura, com finalidade de colaborar com profissionais das áreas de medicina veterinária, biologia e áreas afins. A carcaça de onça parda utilizada neste estudo teve a finalidade de separação e preparação dos ossos para montagem do esqueleto completo, foi oriunda de vítima de atropelamento em rodovia. Os métodos e técnicas utilizadas para a maceração e clareamento foram eficazes, sem a danificação dos ossos, o que favoreceu melhor o resultado e diminuiu significamente danos nas peças anatômicas. Construiu-se assim, um guia capaz de orientar e informar a comunidade cientifica em relação às composições anatômica esqueléticas de uma espécie pouca relatada na literatura internacional.

El agua es uno de los recursos naturales más preciado, en consecuencia, la escasez en algunas regiones sumado a la alta concentración de elementos y sustancias tóxicas provocados por el mal uso y descuido de los seres humanos amenazan en gran medida la sustancia más vital de este planeta. En el caso particular de la industria textil, los colorantes empleados (generalmente azoicos) son compuestos tóxicos y mutagénicos, además, incrementan los valores de DQO y DBO. Por lo tanto, encontrar nuevas estrategias sustentables para los tratamientos de aguas industriales textiles es de suma importancia para poder mitigar el impacto ambiental generado por los colorantes textiles.

De los diversos métodos de tratamientos existe el proceso de adsorción. Para ello, los adsorbentes utilizados generalmente son derivados del petróleo, y en el caso del carbón activado, éstos poseen un alto costo de obtención. En este contexto, el uso de bioadsorbentes renovables es de gran interés para aplicar en estos procesos. Por lo tanto, utilizando un residuo agroindustrial, tal como la cascarilla de soja modificada con adición de grupos catiónicos (CS-Cat) como bioadsorbente, es altamente atractivo y promisorio. Para evaluar la capacidad adsorbente de CS-Cat, como adsorbato se escogió un colorante textil industrial muy utilizado en las industrias de teñidos de telas, tal como Naranja Reactivo 122 (NR122). El NR122 es azoico y posee grupos aniónicos, qué tendrá gran afinidad cuando entre en contacto con la CS-Cat. Para las evaluaciones, se prepararon soluciones de NR122 (10 - 2200 ppm) para las isotermas de adsorción, y de 300, 600 y 1200 ppm de NR122 para cada ensayo en las cinéticas de adsorción.

Los resultados obtenidos a partir de las isotermas y cinéticas de adsorción mostraron una capacidad máxima de adsorción de 705.4 mg/g, y un tiempo máximo de adsorción de 1 h, respectivamente. Los modelos matemáticos que ajustaron a los datos experimentales fueron el modelo de Freundlich para las isotermas, y de pseudo-segundo orden para las cinéticas. Además, se han realizado estudios de diseños de experimentos para buscar las condiciones óptimas en los ensayos de adsorción en columna de lecho empacado utilizando diferentes variables tales como: altura, masa del adsorbente, flujo, y concentraciones de los colorantes. Los resultados experimentales obtenidos mostraron que las curvas de rupturas obtenidas por el proceso de adsorción en columna fueron representadas por el modelo modificado de la curva de dosis-respuesta, obteniéndose un porcentaje de remoción de 79%, y una capacidad máxima de adsorción de 678.1 mg/g.

Decision Consequence Analysis (DCA) of Intervention Alternatives on Landfills Wandir I and II, Volta Redonda (RJ - Brasil)
Authors: Gouvea Júnior Jose Carlos Rocha
Published: January 2023

Decision Consequence Analysis (DCA) is the application of a formalized decision-making process that employs decision theory, probability and statistics (Brown et al, 2010). A decision problem is addressed by disaggregating uncertainties and predicting positive and negative outcomes of possible management approaches. DCA provides a structured model for mapping and evaluating possible outcomes and risks associated with decisions.

The DCA can be used as a decision support system for the management of environmental liabilities. An environmental liability may involve several aspects such as legal, physical, chemical, biological, political, financial and social. Through global analysis of these aspects, logical consequence models are generated to assist the decision maker in choosing the best management alternatives.

In this work, DCA is applied to the management of landfills Wandir I and II, in Volta Redonda (RJ). These landfills received wastes between 1995 and 1997, in an area of almost 140,000 m². After environmental studies initiated in 2000, the area was classified as contaminated and has been the subject of environmental monitoring until the present.

Contamination in soil and groundwater is due to metals and PAHs in concentrations that exceed human health risk thresholds under the hypothetical scenario of groundwater consumption by residents. Alternatives for intervention and site closure were evaluated through DCA.
