TAXATION OF LAW FIRMS IN THE CONTEXT OF THE BRAZILIAN TAX REFORM
The Tax Reform enacted by Constitutional Amendment No. 132/2023 and regulated by Complementary Law No. 214/2025 represents a profound restructuring of the Brazilian tax system by replacing the fragmented model of consumption taxation with a dual system composed of the Tax on Goods and Services (IBS) and the Contribution on Goods and Services (CBS). This article analyzes the impacts of this new regulatory framework on law firms, with emphasis on changes in the tax burden, ancillary obligations, and tax management in the post-reform environment. A qualitative-quantitative methodology is adopted, combining bibliographic and legislative analysis with a comparative numerical simulation of the tax burden under the Simples Nacional regime (Annex IV), the Presumed Profit regime, and the Actual Profit regime, before and after the implementation of the IBS and CBS. The simulations are based on a standardized revenue scenario, allowing an objective measurement of variations in the effective tax burden. The results indicate that, despite the discourse of simplification, the reform tends to significantly increase the tax burden on law firms, mainly due to the limited ability to claim input tax credits, which is characteristic of a labor-intensive sector. The estimated combined IBS and CBS rate of approximately 26.5% negatively affects all regimes analyzed, with greater impact under the Actual Profit regime, followed by the Simples Nacional and the Presumed Profit regimes. It is concluded that the Tax Reform poses substantial challenges to the legal sector, requiring continuous tax planning and strategic action by accounting professionals.

WOMEN, MATHEMATICS AND INVISIBILITY: A SYSTEMATIC LITERATURE REVIEW (2014 – 2024).
This systematic literature review aimed to analyze academic production on the themes of women, mathematics, invisibility, and gender. Search filters were applied to include works published between 2014 and 2024, in open access, in Portuguese, English, and Spanish, developed in Brazil, encompassing articles, theses, and dissertations. Texts that did not directly address the theme were excluded. The survey resulted in 24 studies, 21 authored by women and only three by men, highlighting the leading role of female researchers in the discussion. A greater concentration of publications was identified between 2020 and 2022, particularly from universities in Bahia, Rio Grande do Sul, Rio Grande do Norte, and São Paulo. The most recurrent themes addressed historical invisibility, gender inequality, social stereotypes, and intersectional issues related to race, class, and motherhood. Despite recent progress, gaps remain, such as the scarcity of longitudinal and quantitative studies, as well as research analyzing institutional equity policies. It is concluded that the literature offers important foundations for new investigations and contributes to giving visibility to women in mathematics, reinforcing the role of this production as a subsidy for future research, including this dissertation.
SINTOMAS PSICOPATOLÓGICOS EM HOMENS QUE VIVENCIAM O LUTO PERINATAL: UMA REVISÃO DA LITERATURA
O luto perinatal é uma experiência de potencial impacto emocional, frequentemente marcada por invisibilidade social e institucional, especialmente no que se refere à vivência masculina. Considerando a relevância deste tema, objetivou-se identificar os sintomas psicopatológicos em homens que vivenciam o luto perinatal. Para esse fim, realizou-se uma revisão integrativa da literatura na SciELO, BVS, LILACS e Google Acadêmico. Incluíram-se artigos completos, disponíveis na íntegra, indexados, de acesso livre, nas línguas portuguesa, inglesa e espanhola, publicados no intervalo de 2000 a 2025. Não integraram a amostra os artigos repetidos, textos inacessíveis na íntegra e estudos de natureza não empírica. Adicionalmente, descartou-se a literatura cinzenta, categoria que engloba relatórios, monografias, dissertações e teses. Após as etapas de triagem e leitura na íntegra, sete estudos compuseram a síntese final. Os principais resultados revelaram a presença de sofrimento emocional internalizado, caracterizado por tristeza intensa, ansiedade, culpa e dificuldade de expressão emocional, bem como manifestações externalizantes, como irritabilidade, isolamento social, uso de álcool e comportamentos evitativos. Também foi possível encontrar sintomas compatíveis com luto prolongado e estresse traumático. Por fim, constata-se que o luto perinatal masculino está associado a repercussões significativas na saúde mental, ressaltando-se a necessidade de maior reconhecimento dessa vivência e do desenvolvimento de práticas de cuidado sensíveis aos homens.
EFFICACY OF CONTACT HERBICIDES AND SPRAY VOLUMES IN THE CONTROL OF BURRWEED
Burrweed (Conyza spp.) is one of the main weeds in soybean crops in Brazil, notable for its high competitive potential and resistance to multiple herbicides. The chemical management of this plant has become challenging due to its staggered germination cycle and the spread of resistant biotypes, especially in no-till systems with glyphosate-resistant cultivars. This study aimed to evaluate the interaction between different spray volumes and contact herbicides in controlling burrweed under field conditions. The experiment was conducted in the field in Mandaguari-PR, using a randomized block design with a 4×5 factorial scheme, combining four contact herbicides (diquate, glufosinate-ammonium, saflufenacil, and tiafenacil) and five spray volumes (50, 100, 150, 200, and 250 L ha-1). Spray coverage was monitored with water-sensitive papers, and control efficiency was evaluated at 3, 10, 16, and 22 days after application. Results indicated a strong positive correlation between spray volume and leaf coverage, with maximum coverage recorded at volumes close to 200 L ha-1. However, this increased coverage did not necessarily result in more effective control of burrweed. The herbicide saflufenacil demonstrated higher efficiency across all tested volumes, while diquate was the least effective. The correlation between spray coverage and effective control was weak or nonexistent at the evaluated periods, indicating that the architecture of burrweed, characterized by hairy leaves and vertical growth, compromises the adhesion and penetration of the herbicide spray. Additionally, spray volumes below 100 L ha-1 showed lower efficacy, emphasizing the need for adjustments in application technology. Thus, effective chemical management of burrweed requires applications at early development stages (rosette phase), using volumes around 200 L ha-1, preferably with spray nozzles that ensure uniform drop distribution along the vertical length of the burrweed plants. Integration with cultural practices, such as crop rotation and soil cover, is essential to reduce the weed population and mitigate the risk of resistance evolution. These combined strategies are key to optimizing chemical control of burrweed and ensuring the sustainability of agricultural production.
AN INTEGRATED APPROACH TO THE BIOECOLOGY, SPATIAL DISTRIBUTION, AND FISHERY EXPLOITATION OF THE GOLIATH GROUPER (EPINEPHELUS ITAJARA) IN NORTHERN BRAZIL
This study presents an integrated analysis of the bioecology, population structure, spatial distribution, and fisheries interactions of the Atlantic goliath grouper (Epinephelus itajara) along the northern coast of Brazil. Based on a qualitative and systematized literature review, the research compiles scientific information to support conservation and management strategies. The species plays a key ecological role as a top predator and exhibits ontogenetic habitat shifts, with juveniles inhabiting mangroves and estuaries and adults associated with reef environments, highlighting the importance of habitat connectivity. Biological traits such as slow growth, late maturation, and spawning aggregations increase its vulnerability to overfishing. Findings indicate a concerning population decline in the region, even under fishing moratoria, revealing limitations in enforcement and management effectiveness. Illegal fishing, incidental catch, and habitat degradation remain the main threats. Aquaculture is discussed as a potential complementary strategy to reduce pressure on wild stocks, provided it is sustainably managed. Overall, the study emphasizes the need for integrated conservation actions, including habitat protection, improved fisheries management, and continued scientific research to ensure the long-term recovery and sustainability of E. itajara.
MOBILITY AND LEACHING OF NUTRIENTS IN SOIL COLUMNS WITH THE APPLICATION OF LIQUID SWINE MANURE
Applying organic waste to soil can replenish nutrients removed by crop production and reduce reliance on mineral fertilizers. However, improper use particularly at high application rates can negatively impact the environment. Excess nutrients may leach into water bodies, threatening water quality. Understanding how nutrients move vertically through the soil profile is therefore essential for designing safe and effective fertilization practices. This study aimed to assess the effect of increasing doses of liquid swine manure (LSM) on nutrient mobility in soil and quantify ion leaching. Soil was collected from the 0–0.20 m layer of native Cerrado vegetation. The experiment used a completely randomized design with five LSM application rates (0, 50, 150, 450, and 600 m³ ha⁻¹), each replicated three times. Manure was mixed with soil samples and incubated at 60% field capacity for 20 days. After incubation, a 5 cm layer of treated soil was placed over untreated soil in 100 mm PVC columns. These columns were moistened to field capacity and subjected to five irrigation cycles over 15 days, totaling 400 mm of water. Leachate was collected after each cycle and analyzed via ion chromatography. Nutrient concentrations (Al, Ca, K, Mg, Na, and P), pH, cation exchange capacity (CEC), and water-dispersible clay were measured at 5 cm intervals to a depth of 30 cm. Results showed that the LSM application altered most physical and chemical soil properties, except for K levels and total CEC, which remained unchanged across treatments.
FINITE DIFFERENCE AND MULTIPLE REGRESSION METHODS APPLIED IN DYNAMIC MODELING OF WIND ENERGY
The intermittency of wind energy poses challenges to the stability of the electrical grid, making the precise modeling of the relationship between wind speed and generated power crucial. Traditional models, based on static algebraic equations, are insufficient as they fail to capture the dynamics of the wind and the non-instantaneous responses of the turbine, such as inertia and elasticity. This paper aims to overcome these limitations by developing a dynamic model for wind power, based on a differential equation that describes the temporal evolution of the system. The methodology integrates physical modeling with rigorous statistical analysis, using the Finite Difference Method for the numerical solution of the differential equation, based on classic works in the field. For the calibration and validation of the model against empirical data, the Multiple Regression Method was employed, which allows for analyzing the relationship between power and multiple predictors and evaluating the residuals of the dynamic model. As a result, a particular differential equation describing the dynamic behavior of power was obtained, demonstrating superiority over the static approach, especially under transient wind conditions. The proposed hybrid approach not only offers a more accurate solution for generation forecasting but also establishes a foundation for optimizing control algorithms and future research in the field.
THE INFLUENCE OF THE RELATIONAL HETEROGENEITY OF CREDIT COOPERATIVES ON INNOVATION
The present research aimed to evaluate the influence of relationships with central cooperatives in fostering innovation in singular cooperatives. An exploratory-descriptive study was carried out, operationalized through a quantitative approach and from a positivist epistemological paradigm. Data were collected from 213 cooperatives and analyzed using analysis of variance and linear regression. Furthermore, through factor analysis, the validity and reliability of the investigated constructs were evaluated. Although innovation is an expressively relevant element in cooperativism, there are gaps regarding the broad knowledge about fostering innovation in the context of cooperatives. It was identified that central cooperatives influence the innovation of singular cooperatives, especially if they maintain expressive relational ties, as more widely observed in credit cooperatives. The central cooperative can act in the centralization of innovation activities, as well as enable the formation of closed networks, to minimize opportunistic behavior and favor the transfer of knowledge and resources between cooperatives that are linked to it.
COMPLIANCE NA GESTÃO ACADÊMICA PÚBLICA E A CONTRIBUIÇÃO DA PSICODINÂMICA: UMA REVISÃO BIBLIOMÉTRICA
This study aimed to examine the scientific articles produced on Psychodynamics of Work (PDT) and Compliance, based on publications available in the CAPES/MEC Periodicals Portal from 2019 to 2025. A bibliometric research method was used. The following descriptors were defined: Compliance AND Management; Managers AND PDT; PDT AND Precarious Employment; PDT AND Managers; PDT AND Mental Health; Mental Health AND Managers; and Management AND PDT. With the increase in research on PDT and Compliance, the research sought to answer the following question: how do PDT and compliance connect in public organizations? Using only the CAPES/MEC Portal and articles in Portuguese limited the research and this may have affected the results. The following inclusion criteria were adopted: studies with open access; publications that show the description of the method both in the abstract and in the body of the text; articles that directly address the themes of compliance, management, psychodynamics of work (PDT), mental health, precarious employment, and managers. Articles with publications focused on international contexts unrelated to the Brazilian reality were excluded from this research; works with duplicate entries in the searches or lacking clear methodological rigor were also excluded. The results revealed an analysis of 77 articles, predominantly bibliographic surveys associated with thematic categorical analysis. Descriptive studies with semi-structured interviews and content analysis were also highlighted. Research focusing on document analysis was also identified. Finally, studies that adopted integrative review were noted.
CORPORATE SUSTAINABILITY: AN ANALYSIS OF NATURA &CO’S GRI INDICATORS (2022–2024)
This article analyzes the environmental, social, and governance (ESG) performance of Natura &Co from 2022 to 2024, based on the Global Reporting Initiative (GRI) standards, with the aim of assessing the coherence between reported goals, practices, and results. Methodologically, the study adopts a mixed-methods documentary approach, combining a longitudinal quantitative analysis of selected GRI indicators (GRI 201, 203, 301, 306, 405, and 414) with a qualitative content analysis of corporate sustainability reports, complemented by secondary sources from the specialized literature. The results indicate a high level of institutional maturity in ESG reporting, evidenced by data consistency, the use of derived metrics, and the integration of sustainability into corporate strategy. In the environmental dimension, incremental advances are observed in material circularity and waste management; however, structural challenges persist, such as the absolute increase in non-renewable material consumption and the sensitivity of percentage-based indicators to methodological changes. In the social dimension, the findings highlight progress in gender and racial pay equity and the strengthening of due diligence in the supply chain, contrasted with ongoing limitations in racial and gender diversity at the highest levels of governance. From a governance perspective, even amid financial restructuring, the company maintained social investments and linked financial instruments to ESG targets, reinforcing a shared value creation logic. The study concludes that, although Natura &Co demonstrates advanced ESG reporting and socio-environmental governance practices, further strengthening of the ESG agenda requires more robust metrics, greater standardization of disclosure, and verification mechanisms capable of transforming sustainability reporting into an effective instrument for impact reduction and the promotion of sustainable development, particularly in the Brazilian context.
EDUCATION AS A (IM)POSSIBILITY OF RESISTANCE AND HUMANITY AGAINST BARBARITY
This work addresses the issue of education and the evaluation process in the educational system. To this end, some questions are essential to discover whether education could be decisive in relation to barbarism. Adorno (1995b), at the beginning of his text, starts from the idea that we are all, or should be, against barbarism, because if the subject is educated, he would be more aware of not participating in acts of barbarism. On the other hand, this same author questions the education process in Germany and then asks: what would be the best way to overcome barbarism? Thus, this author analyzes the education process in Germany, since it was in this country that barbarism became most evident, but he also does not fail to mention educational processes in other places to reflect on how the process of debarbarization could be achieved.
OXIDAÇÃO ELETROQUÍMICA DE CORANTE AZO RECALCITRANTE UTILIZANDO ELETRODOS DE DIAMANTE DOPADO COM BORO: DESEMPENHO, OTIMIZAÇÃO E IMPLICAÇÕES AMBIENTAIS
Electrochemical oxidation has emerged as an efficient alternative for the treatment of industrial effluents containing recalcitrant contaminants. In this study, the degradation of the azo dye Acid Black 2 (AB2) in synthetic tannery wastewater was evaluated using electrochemical oxidation with a boron-doped diamond (BDD) anode. The experiments were carried out in a batch system with recirculation, investigating the influence of initial dye concentration, current density, pH, electrolyte concentration, and reaction time through a Taguchi experimental design (L25). The evaluated responses included color removal, chemical oxygen demand (COD) removal, total organic carbon (TOC) removal, and specific energy consumption. High removal efficiencies were achieved, reaching up to 95.7% for AB2, 97.4% for COD, and 83.6% for TOC. Multi-objective optimization using the desirability function indicated optimal operating conditions associated with acidic pH, low initial dye concentrations, and moderate current densities, allowing high treatment efficiency with reduced energy consumption. Kinetic studies revealed a shift in the degradation mechanism, with second-order behavior under preliminary conditions and first-order kinetics under optimized conditions. Ecotoxicological assays using Artemia salina showed no statistically significant increase in toxicity after electrochemical treatment. Overall, the results demonstrate that electrochemical oxidation using a BDD anode, combined with statistical optimization tools, represents a promising and environmentally safe advanced treatment technology for tannery effluents containing recalcitrant azo dyes.
METODOLOGIAS ATIVAS NO ENSINO DE ENGENHARIA CIVIL:
The teaching of Occupational Health and Safety (OHS) in Civil Engineering undergraduate programs has historically faced the challenge of overcoming traditional passive methods, which often result in a gap between normative theory and the practical reality of construction sites. In this context, this study aimed to analyze the effects of implementing active learning methodologies, specifically Problem-Based Learning (PBL) and Team-Based Learning (TBL), in the teaching-learning process of the OHS discipline at Centro Universitário Araguaia. Methodologically, the study is classified as applied action research with a mixed-methods approach, involving a census of 12 students from the 2025/1 cohort. The pedagogical intervention consisted of the technical development of Risk Maps in the institution's real environments, subsequently evaluated through a structured questionnaire. Results demonstrated that 100% of the students considered the activity extremely relevant to their professional training. It was observed that the practical identification of risks, especially ergonomic and accident-related ones, generated a positive cognitive imbalance, requiring greater critical thinking compared to physical and chemical risks. The teamwork dynamics (TBL) were rated as effective by over 90% of the class, fostering positive interdependence. It is concluded that the integration of PBL and TBL was decisive in consolidating a preventionist culture, promoting the development of technical and socio-emotional skills essential for the contemporary engineer, and transcending mere rote memorization of standards.
The Cosmetic Urbanism and the Emptying of Brasília’s Setor Comercial Sul: The Case of Block 05
This article analyzes Block 05 of the Setor Comercial Sul (SCS) in Brasília as a case study to discuss the limits of urban renewal policies centered on physical and infrastructural interventions in public space. Starting from the diagnosis of functional emptying in central areas in the Brazilian context, intensified by economic shifts and the post-pandemic period, it argues that improvements to sidewalks, paving, lighting, and urban furniture, although important, do not automatically translate into urban activation when they are disconnected from the social, economic, and institutional dynamics that sustain everyday vitality. Methodologically, the research combines documentary analysis of public projects and actions, on-site observation across different days and time periods, and data triangulation, supported by three-dimensional modeling to spatialize the evidence. The discussion draws on the frameworks of Jacobs, Gehl, and Milton Santos to interpret the mismatch between upgraded fixed urban elements and weakened urban flows, showing how vacancy, inactive street fronts, and vulnerabilities intensify in low-visibility layers such as service lanes and the underground level. It concludes that the activation of the SCS depends on continuous territorial governance, diversification of uses, strengthening of the local economy, and coordinated strategies for care and everyday safety.
ANALYSIS OF THE APTITUDE FOR THE IMPLEMENTATION OF COMMUNITY-BASED TOURISM IN THE COMMUNITY OF MANGUE SECO, RAPOSA (MARANHÃO, BRAZIL).
Tourism is a multidisciplinary activity that uses the culture and natural resources of a receiving location as its main elements. Mass tourism, disorderly, causes the depreciation of socio-environmental attributes, harming tourist activity. In this context, Community-Based Tourism (CBT) presents itself as a proposal for the development of tourism with the potential to promote socio-environmental sustainability in the context of traditional communities. This article aims to analyze the aptitude for the implementation of CBT in the community of Mangue Seco, municipality of Raposa-MA, which receives visitors spontaneously and with little protagonism of the community. A qualitative-quantitative, exploratory-descriptive approach was used, integrating the ethnographic and phenomenological perspectives, and the Tourist Attractiveness Index (TAI) was adapted, whose values are limited between 0 and 5. The results showed an average IAT of 2.90, with the lowest IAT for the management attribute (less than 2.0) showing that fitness is influenced by little or no basic infrastructure such as sanitation, water supply and energy. The highest IAT was obtained for the biophysical and social attributes (between 3.0 and 4.0), revealing the locality as a potential destination of regional relevance. An integrated and participatory management is recommended for the search for sustainable alternatives and in coherence with the local reality so that CBT becomes a successful strategy.
STUDY OF THE RATE OF CHANGE AS A TOOL FOR COST ANALYSIS IN PRODUCTIN ENGINEERING
This article investigates the application of rates of variation in Production Engineering, with an emphasis on cost and investment analysis using differential calculus. The objective is to conduct practical simulations, using fictitious examples, to examine the behavior of fixed, variable, and total costs, highlighting how these elements can inform strategic decisions related to investments and the control of production processes. The theoretical foundation is based on classical calculus frameworks and applied studies in the field, while the proposed examples demonstrate how the use of the first and second derivatives makes it possible to identify points for maximizing profits and minimizing losses, contributing to the improvement of production management.
CIÊNCIA, COMUNIDADE E O CERRADO: RELATO DE EXPERIÊNCIA SOBRE AÇÕES EXTENSIONISTA DO NÚCLEO DE EDUCAÇÃO AMBIENTAL – AGNES WADELL CHAGAS NA SEMANA NACIONAL DE CIÊNCIA E TECNOLOGIA, GOIÁS, 2024
This article reports on the outreach experience of the Environmental Education Center – Agnes Wadell Chagas (NEA) during the 2024 National Science and Technology Week, held at the Cerrado Experimental Unit in Cocalzinho de Goiás, Brazil. Based on the thematic proposal "Biomes of Brazil: diversity, knowledge, and social technologies," the event promoted educational activities aimed at popularizing science. Workshops, interactive stations, recreational activities, and exhibitions were conducted, integrating scientific knowledge with local cultural and environmental practices. The initiative engaged with topics such as biodiversity, sustainability, renewable energy, intercultural education, and climate change, aiming to foster critical reflection and strengthen the bond between university and community. The methodology adopted emphasized dialogical communication, active participation, and the collective construction of knowledge. The results indicate that the event contributed to the civic and environmental education of participants, highlighting the importance of outreach initiatives as tools for social transformation, the appreciation of the Cerrado biome, and the fight against social inequalities.
This article analyzes the Life Project (LP) component in the New High School in light of Pierre Bourdieu's theory. The discussion demonstrates how the LP, aligned with neoliberal agendas, shifts responsibility for social equity from the state to the individual, under the rhetoric of self-entrepreneurship. The work uses the concept of cultural capital and its ramifications to show that the school, by presenting itself as a neutral instance, legitimizes the culture of the dominant classes. The analysis reveals that success in planning for the future, as required by LP, depends on dispositions and symbolic resources acquired previously within the family. By treating socially unequal students equally, the education system converts privileges of origin into individual merit, acting as a tool of symbolic violence. It is concluded that the Life Project, far from mitigating disparities, reinforces social reproduction by ignoring the structural barriers that condition the trajectories of Brazilian youth.
Autism Spectrum Disorder: from biological understanding to individualized education program
The inclusion of people with disabilities, in such a way to respect their dignity and rights granted by law, is a global challenge. Although the technological advances of the 1990s have guided policies towards equitable treatment, the success of inclusion fundamentally depends on social perception of neurodiversity. Disseminating information about disabilities and raising public awareness are crucial to combating prejudice. This article aims to offer a comprehensive and interdisciplinary view of Autism Spectrum Disorder (ASD), based on the scientific, socio-political, and educational pillars that support the inclusion process. After a brief presentation of the concept of disability, several aspects of neurodevelopment are related to the symptomatology of autism, with emphasis on genetic and epigenetic aspects. The research-extension project presented below was conducted in a community center in the city of Belém (PA) and used an approach based on Applied Behavior Analysis. An individualized intervention plan was developed to meet the needs of a 12-year-old with level 2 autism spectrum disorder, starting with his favorite video game. The use of positive reinforcement, the development of goals together with the young person, and the creation of friendly bonds proved to be valuable tools for improving the young person's target behavior.
Uma LOCALIZAÇÃO EFICIENTE DE ESTAÇÕES DE RECARGA E AVALIAÇÃO DA VIABILIDADE PARA RECARREGAR VEÍCULOS ELÉTRICOS
Despite the significant growth of electric mobility globally, the consolidation of charging infrastructure still represents one of the main problems to the widespread use of electric vehicles, especially in developing countries. Considering the challenges and opportunities related to the electric vehicle charging infrastructure, this study aims to develop an efficiency model for the best location of future charging stations for electric vehicles. To this end, a survey was conducted covering the entire length of the BR-386 highway, for each 2 km, under concession to CCR-Via Sul. This data was used in the Decision Support System for electric highways application (SAD Eletrovias), developed in this work, using the AHP multi-criteria methodology. The application of this work determined the selection of the best locations for future charging stations for electric vehicles, as well as assisting in important factors in decision-making.
This article addresses urban afforestation as a structuring element of city planning with emphasis on the Cerrado biome. It is based on the understanding that the presence of trees in urban spaces goes beyond the aesthetic dimension, being directly related to climate regulation, environmental quality, and the population’s well-being. Although these benefits are widely recognized in the literature, it is observed that, in practice, urban tree planting is still not consistently incorporated into Brazilian urban planning. The methodology was based on a literature review, consulting articles in CAPES journals. The results demonstrate the need to rethink urban planning so that trees can be incorporated as essential infrastructure, fundamental to fulfilling their ecological, social, and economic functions, thereby enabling quality of life in cities.
