Published: April 2021

Diversas pesquisas defendem que o conjunto dos principais fatores determinantes do comportamento de consumo sustentável ainda não é suficientemente claro, sendo necessários esforços adicionais que possibilitem avanços nesse sentido. Partindo dessa lacuna, o objetivo desta pesquisa foi identificar os principais fatores determinantes do consumo sustentável já identificados mundialmente. Este estudo foi desenvolvido através do método da revisão sistemática de literatura. Para tanto foram definidos 7 termos de busca, pesquisados na base de dados Web of Science. Ao final das buscas e análises, compuseram a amostra de estudo 143 artigos. Por meio da revisão, foram identificados 21 fatores que se destacam como determinantes do consumo sustentável, dentre os quais a consciência ambiental se sobressai. Entretanto vários fatores menos intuitivos ou evidentes também foram verificados. Por exemplo: Acesso às redes sociais; Nível de religiosidade; Taxa de penetração do transporte público; Amor pela posse material; Taxa de urbanização; Emoções, entre outros. Os resultados do estudo contribuem para a formação de uma abordagem teórica mais sólida para se analisar e entender o comportamento de consumo sustentável. Almeja-se por meio disso proporcionar às empresas um melhor delineamento dos fatores motivadores do consumo sustentável, que em posse de tais informações, poderão desenvolver estratégias mais assertivas no atendimento das demandas desse público, potencializando suas vendas, bem como contribuindo para a solidificação do desenvolvimento sustentável.
O Direito Humano à Água e a Regulação do Saneamento Básico no Brasil: Tarifa Social e Acessibilidade Econômica
Authors: Reis Camila Antonieta Silva , Carneiro Ricardo
Published: April 2021

O acesso à água potável e ao esgotamento sanitário é notoriamente reconhecido como uma condição essencial à proteção da saúde e à preservação da vida, tendo sido definido, por resolução da Organização das Nações Unidas (ONU), de 2010, como direito humano essencial.  Essa essencialidade ganha contornos particularmente nítidos no atual contexto, marcado pela pandemia da Covid-19. Para a promoção de objetivos sociais e econômicos relacionados à provisão dos referidos serviços, o marco regulatório do setor de saneamento básico brasileiro introduziu a necessidade de instituição de agências independentes com a atribuição de disciplinar e fiscalizar as atividades das empresas atuantes na área. Dentre os diversos desafios postos à atividade reguladora ressalta-se a dificuldade de acesso, pela população de baixa renda, aos serviços setoriais. Um dos instrumentos usualmente empregados para oportunizar esse acesso é a denominada Tarifa Social. Nesse contexto, o artigo busca traçar uma visão panorâmica de sua utilização, em âmbito nacional, na prestação dos serviços setoriais, utilizando-se de dados do Sistema Nacional de Informações sobre Saneamento – SNIS. Verificou-se que o instrumento se faz presente na maior parte dos municípios, constatando-se, entretanto, grande heterogeneidade nos critérios adotados para sua concessão que, muitas vezes, se dissociam do principal objetivo de sua instituição.

Published: April 2021

O artigo analisa a relação entre o processo de urbanização nacional e o direito de propriedade relacionados à moradia, com base nos estudos de Douglass North, da Nova Economia Institucional (NEI). A metodologia é caracterizada por um estudo exploratório a partir de uma revisão de literatura referente ao processo de urbanização brasileiro e a abordagem sobre do direito de propriedade sob a perspectiva da teoria econômica institucionalista. Os resultados teóricos e empíricos acumulados pela NEI oferecem um instrumental importante para uma melhor compreensão das várias interfaces entre o sistema econômico e as instituições legais e jurídicas que condicionam as atividades e transações econômicas relacionadas à moradia. As ideias de North mostraram-se adequadas na discussão do tema, haja visto que se o direito de propriedade for mais bem definido, atribuído e garantido nessas comunidades, menores serão os custos de transação e, conseqüentemente, maior será o valor do ativo e da renda do proprietário deste.

CO2 REDUCTION TO HYDROCARBONS AND OXYGENATES: FUNDAMENTALS, STRATEGIES AND CHALLENGES. The development of renewable energy sources (e.g., solar and wind) moves foward, the tendance for replacing fossil fuels increases. However, these technologies have as primary barriers to industrial processes’ efficiency and especially storage. Thus, CO2 reduction routes using these energy sources could chemically store part of the energy as fuels or chemicals, offering alternatives to current oil and gas industry. This process is inspired by photosynthesis, e.g., photochemical or electrochemical processes, using homogeneous or heterogeneous catalysts. Nevertheless, this reaction is thermodynamically unfavorable and has very slow kinetics, given the high stability of the CO2 molecule and the complexity of the redox reactions involved. Therefore, this review addresses this process’s kinetic and thermodynamic challenges, and the fundamental concepts of the photo(electro)chemical processes for CO2 reduction, besides presenting and discussing the materials with the potential to act as catalysts. The main reaction mechanisms and advances in the understanding of such processes are discussed, as well as future perspectives

Published: April 2021

This paper highlighted the social change of peasant in the process of facing any struggling movement. Applying a qualitative method and case study approach, the data in this research were collected by observation, interview, and document study. The data were analyzed using the theory of “Social-Economic Morality”. By analyzing the data using this theory this article revealed the changing society in terms of peasant political attitude. This research found three important aspects. Firstly, compromise is a kind of strategy applied by peasants in their movement. Because there are no supporting factors for peasants to avoid the state’s hegemony and exploitation, so the only strategy to deal with the expansive tendency of capitalism is by changing the political attitude of peasants. Secondly, the organizational consolidation is claiming peasant’s rights. Thirdly, capacity development through the empowerment process is a form of compromise way of peasants’ movement. These three compromise models are the ways to avoid conflict to escalate.

Published: April 2021

Reformation-era opened the opportunities for political freedom and the development of religious life among the Islamic community in Indonesia. It can be seen in the strengthening of the identity and the movements of religious groups outside the mainstream religious groups, namely radicalism. Acceptance of different narratives based on religious sentiments is shown in the public space by building a distinction between "us" and "them". There is a need for an antidote toward radical understanding that resulted in acts of terror naming the deradicalization. By qualitative methods, this study indicated that during the nine years of the establishment of the National Counterterrorism Agency (BNPT) the programs are still static because the program has not been able to minimize or even eliminate radical understanding that led to acts of terror. All elements of civil society must strengthen the deradicalization program of BNPT. Both NGOs (Wahid Institute and SETARA Institute) stated that the process of deradicalization was not only on individual problems, but the social environment also played an active role. It is the state that has the ability in the process of deradicalization, but the state must involve civil society.

Generally, emigrants have a deep interest in the condition of their hometown. In the Minang community, that sense is called "raso banagari", a sense of belonging to the nagari. One form of embodiments of raso banagari is to participate in the development of nagari, both directly and indirectly. Managing the participation of nagari emigrants in the Solok Regency, the Solok Regent made policy in the form of Regent Regulation Number 10 of 2017 concerning Collaboration between the Regional Government and the Nagari Government with Solok Emigrants. Solok Regency has 47 nagari emigrant organizations out of 70 nagari(s). This study aims to determine and analyze the form and level of emigrant participation in nagari development in Solok Regency. This research uses a combination of quantitative and qualitative methods. The results showed that the form of emigrant participation in the development of the nagari was mostly in the form of donations of money, ideas, and networking.
The Transformation of Noken Papua: Understanding the Dynamics of Noken’s Commodification as the Impact of UNESCO’s Heritage Recognition
Authors: Salhuteru Alice , Hutubessy Fred Keith
Published: April 2021

This research was motivated by previous studies that discussed Noken from various points of view but did not examine aspects of the commodification of Noken as an implication of the world heritage label from UNESCO. Noken is a native Papuan knit bag that has high cultural values, sacred entity, and a source of life; as a container for carrying garden products and animal hunting products. Noken is also a form of maturity initiation, Papuan woman who can knit noken may enter the marriage phase. Applying the qualitative method, with observations and interviews with women knitting and selling it in Jayapura as informants, this study found that: firstly, Noken had undergone massive economic commodification, started with UNESCO's recognition of inherited noken as intangible, which led to more and more traded noken. Secondly, noken has transformed values, especially about the noken value that animates them. The transformation of values in noken is a necessity in the dynamics of the social, economic, and cultural changes of the Papuan. Thirdly, by knitting and selling it, they are trying to preserve the sacred value of noken, also as a strategy to survive economically in encountering the impact of the capitalist system.
Mekanisme Survival Petani “Gurem” pada Masa Pandemi COVID-19

Published: April 2021

Small-scale farmers in Tlogosari, Pagak, Malang have many limitations, especially economically. Instead of wanting to improve economic prosperity, small-scale farmer makes changes to the commodities they grow from sugar cane to sengon (Paraserianthes falcataria (L) or albizia). But the change in this commodity has an impact on changing the pattern of short to long harvests. This condition has increasingly resulted in the economic downturn of the farming family, coupled with the existence of the COVID-19 pandemic, making farmers increasingly powerless. This research focuses on the survival mechanism of small-scale farmers who switch commodities from sugar cane to sengon during the COVID-19 pandemic. This study uses James Scott's theory of the ethics of subsistence as a knife of analysis and uses a qualitative approach with a case study method. The research informants were determined by purposive sampling with the criteria of small-scale farmer informants who were affected by the COVID-19 pandemic due to the change of sugarcane commodity to sengon. The price of sengon during the COVID-19 pandemic dropped dramatically due to many factories closed, so farmers are also confused looking for sengon buyers. This condition makes small-scale farmers feel like poor famine. Faced with such conditions, smallholders do survival by other work, namely making gatot, tiwul, and corn grits (ampok) as a profitable employment opportunity in the future of COVID-19
Health-risk assessment for roof-harvested rainwater via QMRA in Ikorodu area, Lagos, Nigeria

Published: April 2021

This paper presents a study to assess the roof-harvested rainwater (RHRW) in the Ikorodu area of Lagos state, Nigeria, and recommends guidance to minimise the health risk for its households. The types, design and use of rainwater harvesting systems have been evaluated in the study area to inspect the human risk of exposure to Escherichia coli (E. coli). To achieve these objectives, a detailed survey involving 125 households has been conducted which showed that 25% of them drink RHRW. Quantitative microbial risk assessment (QMRA) analysis has been used to quantify the risk of exposure to harmful E. coli from RHRW utilised as potable water, based on the ingestion of 2 L of rainwater per day per capita. Results have revealed that the maximum E. coli exposure risk from the consumption of RHRW, without application of any household water treatment technique (HWTTs) and with application of alum only, were 100 and 96 respectively, for the estimated number of infection risk per 10,000 exposed households per year. This estimation has been done based on 7% of E. coli as viable and harmful. Conclusively, it is necessary that a form of disinfectant be applied to the RHRW before use.

The security of water environment in the source region of the Yangtze River (SRYR) is vital to the water environment security of the whole basin. The results showed that the rivers in the SRYR were weakly alkaline and the values of total solid solubility (TDS), electrical conductivity (EC), turbidity concentration and salinity were higher than the values in the middle and lower reaches of the Yangtze River. The results showed that the dissolved trace elements detected displayed obvious regional distribution characteristics, showing a high concentration trend in the Chumar River, low in the Dangqu, and middle in the Tong River. All water quality indexes in the SRYR met the surface water environmental quality standard of class II based on GB 3838-2002 except Hg, while the average concentration of As exceeded 10 μg/L. The main enrichment elements in the SRYR were Li, Se, As and Pb, and their concentrations were far higher than the average concentration of the world rivers. Moreover, the HI and HQingrstion of children caused by As in the SRYR were greater than 1. This study could provide basic data for water environment protection and water resource management in the SRYR.

Highly populated coastal environments receive large quantities of treated and untreated wastewater from human and industrial sources. Bivalve molluscs accumulate and retain contaminants, and their analysis provides evidence of past contamination. Rivers and precipitation are major routes of bacteriological pollution from surface or sub-surface runoff flowing into coastal areas. However, relationships between runoff, precipitation, and bacterial contamination are site-specific and dependent on the physiographical characteristics of each catchment. In this work, we evaluated the influence of precipitation and river discharge on molluscs' Escherichia coli concentrations at three sites in Central Italy, aiming at quantifying how hydrometeorological conditions affect bacteriological contamination of selected bivalve production areas. Rank-order correlation analysis indicated a stronger association between E. coli concentrations and the modelled Pescara River discharge maxima (r = 0.69) than between E. coli concentration and rainfall maxima (r = 0.35). Discharge peaks from the Pescara River caused an increase in E. coli concentration in bivalves in 87% of cases, provided that the runoff peak occurred 1–6 days prior to the sampling date. Precipitation in coastal area was linked to almost 60% of cases of E. coli high concentrations and may enhance bacterial transportation offshore, when associated with a larger-scale weather system, which causes overflow occurrence.

O objetivo do presente trabalho foi conhecer a distribuição dos gêneros Nealeurodicus e Octaleurodicus no estado do Rio de Janeiro, bem como suas plantas hospedeiras, buscando contribuir para um inventário dos representantes da subfamília Aleurodicinae nessa unidade da Federação. As coletas foram realizadas de forma aleatória, de 2005 a 2018, em folhas das plantas hospedeiras de vias públicas, residências particulares, casas de vegetação, lavouras comerciais de pequeno e médio porte, como também no Instituto Zoobotânico de Morro Azul (IZMA), localizado no município de Engenheiro Paulo de Frontin (RJ). Analisou-se também o acervo Ângelo Moreira da Costa Lima, situado na Universidade Federal Rural do Rio de Janeiro. Foram amostradas as espécies Nealeurodicus moreirai Costa Lima e Octaleurodicus nitidus Hempel, distribuídas em 10 municípios do Rio de Janeiro, e registradas 18 novas plantas hospedeiras. N. moreirai é a espécie mais dispersa do estado, ocupando seis municípios em três regiões: Metropolitana, Serrana e Sul Fluminense. Este trabalho amplia o número de municípios pesquisados no estado, pois os levantamentos já realizados avaliaram a fauna de aleirodídeos em geral somente em agroecossistemas citrícolas. Fica demonstrado que há necessidade de novos levantamentos relacionados a moscas-brancas, assim como pesquisas em taxonomia visando à ampliação de conhecimento do referido grupo.

A domesticação de espécies nativas de parasitoides em laboratório é de grande interesse, pois, como elas já estão adaptadas aos agroecossistemas brasileiros, sua liberação pode resultar em aumento de sua população em campo. Os objetivos da presente pesquisa foram estabelecer um processo de domesticação do parasitoide nativo Doryctobracon areolatus (Szépligeti, 1911) em laboratório e estudar aspectos do comportamento de parasitismo. Para iniciar o processo de domesticação, realizaramse coletas de frutos em pomares de áreas rurais, para a obtenção de espécimes de D. areolatus. A partir dos insetos obtidos em campo, foi iniciada a domesticação do parasitoide em laboratório. O processo de domesticação foi descrito, sendo mantida a criação de D. areolatus por cinco gerações. Avaliou-se a idade ideal das larvas hospedeiras para permitir a melhor porcentagem de parasitismo e a proporção de fêmeas na progênie. A maior proporção de larvas parasitadas e superparasitadas e o maior índice de parasitismo foram obtidos quando larvas de Anastrepha fraterculus de seis/sete dias de idade foram oferecidas às fêmeas de D. areolatus. A razão sexual não foi alterada com a idade da larva hospedeira. Discutiram-se os principais problemas na domesticação de parasitoides a partir de insetos obtidos em campo sobre outros hospedeiros.

A canafístula [Peltophorum dubium (Sprengel) Taubert (Fabaceae)] é uma espécie nativa promissora para a produção de madeira. Assim, para a formação das mudas, a profundidade das sementes e a sua posição de deposição na semeadura são alguns dos vários fatores que exercem influência no seu crescimento e desenvolvimento. O objetivo do presente trabalho foi avaliar a produção de mudas de canafístula, em função da posição da semente no substrato e da profundidade de semeadura. O experimento foi conduzido em casa de vegetação em delineamento experimental de blocos ao acaso, dispostos em esquema fatorial 5 x 3, sendo os fatores constituídos por cinco posições (A – hilo para baixo, B – hilo para cima, C – hilo e “dorso” de lado, D – “dorso” para baixo, E – “dorso” para cima) e três profundidades de semeadura (1, 3 e 5 centímetros), com quatro repetições. As contagens do número de plântulas emergidas foram diárias, do 6.º até o 15.º dia após a semeadura, quando se determinou o índice de velocidade de emergência. Aos 30, 60, 90 e 120 dias após a emergência avaliaram-se: altura de planta, diâmetro do coleto, quociente de robustez por meio da relação altura/diâmetro do coleto, número de folhas, volume radicular, massa seca aérea e das raízes, relação entre a massa seca aérea/raízes e o índice de qualidade de Dickson. O melhor desenvolvimento e qualidade final das mudas de canafístula ocorrem quando as sementes são semeadas na profundidade de 1 cm nas posições C e D ou na profundidade de 3 cm nas posições A, D e E.

Radiomic and Genomic Machine Learning Method Performance for Prostate Cancer Diagnosis: Systematic Literature Review
Authors: Castaldo Rossana , Cavaliere Carlo , Soricelli Andrea , Salvatore Marco , Pecchia Leandro , Franzese Monica
Published: April 2021

Background

Machine learning algorithms have been drawing attention at the joining of pathology and radiology in prostate cancer research. However, due to their algorithmic learning complexity and the variability of their architecture, there is an ongoing need to analyze their performance.

Objective

This study assesses the source of heterogeneity and the performance of machine learning applied to radiomic, genomic, and clinical biomarkers for the diagnosis of prostate cancer. One research focus of this study was on clearly identifying problems and issues related to the implementation of machine learning in clinical studies.

Methods

Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, 816 titles were identified from the PubMed, Scopus, and OvidSP databases. Studies that used machine learning to detect prostate cancer and provided performance measures were included in our analysis. The quality of the eligible studies was assessed using the QUADAS-2 (quality assessment of diagnostic accuracy studies–version 2) tool. The hierarchical multivariate model was applied to the pooled data in a meta-analysis. To investigate the heterogeneity among studies, I2 statistics were performed along with visual evaluation of coupled forest plots. Due to the internal heterogeneity among machine learning algorithms, subgroup analysis was carried out to investigate the diagnostic capability of machine learning systems in clinical practice.

Results

In the final analysis, 37 studies were included, of which 29 entered the meta-analysis pooling. The analysis of machine learning methods to detect prostate cancer reveals the limited usage of the methods and the lack of standards that hinder the implementation of machine learning in clinical applications.

Conclusions

The performance of machine learning for diagnosis of prostate cancer was considered satisfactory for several studies investigating the multiparametric magnetic resonance imaging and urine biomarkers; however, given the limitations indicated in our study, further studies are warranted to extend the potential use of machine learning to clinical settings. Recommendations on the use of machine learning techniques were also provided to help researchers to design robust studies to facilitate evidence generation from the use of radiomic and genomic biomarkers.

Development of a Theoretically Informed Web-Based Mind-Body Wellness Intervention for Patients With Primary Biliary Cholangitis: Formative Study (Preprint)
Authors: Watt Makayla , Spence John C , Tandon Puneeta
Published: April 2021

BACKGROUND

Mind-body interventions have the potential to positively impact the symptom burden associated with primary biliary cholangitis (PBC). Interventions are more likely to be effective if they are informed by a theoretical framework. The Behaviour Change Wheel (BCW) and the behaviour change technique taxonomy version 1 (BCTv1) provide frameworks for intervention development.

OBJECTIVE

This study describes how theory has guided the development of a 12-week multicomponent mind-body wellness intervention for PBC.

METHODS

The steps involved in developing the BCW intervention included specifying the target behavior; explaining barriers and facilitators using the Capability, Opportunity, Motivation, and Behaviour and the theoretical domains framework; identifying intervention functions to target explanatory domains; and selecting relevant behavior change techniques to address intervention functions. Qualitative data from patients with inflammatory bowel disease using an earlier version of the program and feedback from a PBC patient advisory team were used to guide intervention development.

RESULTS

Barriers and facilitators to intervention participation associated with capability, opportunity, and motivation were identified. Intervention functions and behavior change techniques were identified to target each barrier and facilitator.

CONCLUSIONS

The Peace Power Pack PBC intervention was developed to help individuals with PBC manage their symptom burden. The theoretical frameworks employed in this intervention provide direction on targeting antecedents of behavior and allow standardized reporting of intervention components.

The role of mobile health systems in improving hypertension management and awareness: a systematic review (Preprint)
Authors: SNCS Ammad Uddin
Published: April 2021

BACKGROUND

Elevated blood pressure (BP), or hypertension, is a serious medical issue that affects the function of almost all other body organs, including the heart, brain and kidneys, and is a major cause of related diseases. High BP is known as the "silent killer" because in most cases, the patient feels no warning signs or symptoms. Lack of or late detection of this disease may cause more complications or even life-threatening consequences. For this reason, it is essential that BP is measured, logged, and reported regularly. Regular preventive visits to healthcare providers just for BP measurement and tracking may not be feasible for most people. To address this, recent studies have focused on self-management of hypertension using cellular phone technologies, which has been proven to be an effective tool for early detection and control of high BP without affecting patients’ daily routines.

OBJECTIVE

To identify the limitations, shortcomings, and gaps in the research related to the impact of mobile technology for managing hypertension.

METHODS

This study was conducted in June, 2020 and we surveyed some existing self-monitoring systems and evaluated their effectiveness and compared them with each other.

RESULTS

We investigated the existing systems in terms of methods used, sample size, type of investigation, input and output attributes, rate of success in controlling BP, group of users with higher response rate and beneficiaries, and acceptability and adherence of the system. We identified some limitations, shortcomings, and gaps in the research related to the impact of mobile technology for managing hypertension. These shortcomings can inform future research, enabling it to become more realistic and adaptive.

CONCLUSIONS

Based on limitations founded in existing system we have recommended including more observable factors and human behaviors that affect BP. Furthermore we suggested that vital monitoring/logging and medication tuning are not enough to improve control of hypertension, as there is also a need to observe and alter patient behavior and lifestyles.
Ability of Ectoine to Stabilize Lipase against Elevated Temperatures and Methanol Concentrations

Published: April 2021

Ectoine is one of the compatible organic molecules that can protect the protein from heating, freezing, and chemicals contact. This study aims to investigate the ability of ectoine to stabilize lipase on heating and in methanol treatments as an effort to provide a stable biocatalyst for the production of biodiesel. Various ectoine concentrations were added to lipase solutions, then the mixture was heated, and the residual activity of the lipase was determined. Similar steps were also conducted for methanol treatment. The results showed that ectoine maintained and even improved the catalytic activity of lipase after treatment with either heat or methanol. The addition of ectoine to a final concentration of 110 to 150 mM could maintain lipase activity up to 80% when heating to approximately 95 °C. Additionally, more than 20% of lipase activity increased on heating to temperatures below 75 °C in the presence of ectoine at a final concentration of 25 to 120 mM. Meanwhile, after incubation in methanol at a level of around 84% (v/v), the activity of lipase containing 40–90 mM ectoine was maintained. These results demonstrated that ectoine was highly effective in protecting lipase from heat and methanol.
Potential Screening of Bacteriocinogenic-Lactic Acid Bacteria from Mangrove Sediment of Logending Beach for Fisheries Product Preservation

Published: April 2021

The meat and fisheries products have high nutritional content which is highly ideal for bacterial growth. Lactic Acid Bacteria (LAB) have several potential advantages as a bio-preservative agent in the food industry because they produce antimicrobial substances against pathogenic bacteria e.g. bacteriocin. Our previous study has succeeded in isolating and characterizing LAB from the mangrove sediments of Logending Beach, Kebumen. This present study aimed to determine the activity of bacteriocinogenic-LAB against food-borne pathogens and their potential for fisheries product preservation. The study consisted of five serial stages, as follows: screening of LAB isolates, cell-free supernatant production and its inhibition activity, extraction of partially purified bacteriocin, bacteriocin confirmation against proteolytic enzymes, and in-vitro test of partially-purified bacteriocin against Listeria monocytogenes, Shigella flexneri, and Salmonella typhi. A total of 25 out of 99 isolates were able to grow on MRSA+1% CaCO3 medium. Initial screening showed that the cell-free supernatant of 14 LAB isolates was able to inhibit the growth of S. thypi, S. flexneri, and L. monocytogenes. There was an increased inhibitory activity of partially purified bacteriocin when compared with the cell-free supernatant which was statistically different (p<0.01). It indicated that the purification was successfully performed. Bacteriocin expressed a lower inhibition against S. typhi than L. monocytogenes and S. flexneri. The ANOVA test showed that each indicator pathogenic-bacterium expresses a very significant sensitivity to the partially purified bacteriocin.
