What has been neglected in much of the existing studies of the influence of seasonal and regional characteristics of agriculture on the market power and national security. This paper constructs a multivariate equations model to investigate the monopoly power of seasonal suppliers and national security in China's soybean market. The results show no relationship between market share and monopoly power; and that CR3 and HHI show China's soybean import market has been the highest oligopoly type, but the model suggest that exporters (the U.S., Brazil and Argentina) have very weak monopoly power and China has no monopsony power; and that the performance of some exporters' soybeans is affected by others, while others are relatively independent in market. This is due to the non-substitutability of the product, the non-substitutability of the buyer and the seller, etc., which causes the mutual dependence of the seller and buyer, and their market power cancel each other out. The seasonality and regionality of soybean production is the root. Considering national security, it is necessary to take the seasonal and regional characteristics of exporters into account to disperse trade risks and oppose monopolisation of international food production and trade.

Raw observations (carrier-phase and code observations) from the Global Navigation Satellite System (GNSS) can now be accessed from Android mobile phones (Version 7.0 onwards). This paves the way for GNSS data to be utilized for low-cost precise positioning or in ionospheric or tropospheric applications. This paper presents results from data collection campaigns using the CAMALIOT mobile app. In the first campaign, 116.3 billion measurements from 11,828 mobile devices were collected from all continents. Although participation decreased during the second campaign, data are still being collected globally. In this contribution, we demonstrate the potential of volunteered geographic information (VGI) from mobile phones to fill data gaps in geodetic station networks that collect GNSS data, e.g. in Brazil, but also how the data can provide a denser set of observations than current networks in countries across Europe. We also show that mobile phones capable of dual-frequency reception, which is an emerging technology that can provide a richer source of GNSS data, are contributing in a substantial way. Finally, we present the results from a survey of participants to indicate that participation is diverse in terms of backgrounds and geography, where the dominant motivation for participation is to contribute to scientific research.

A regional approach to the study of Brazil's beef industry is increasingly relevant as deforestation takes centre stage in policy debates worldwide. To what extent has beef production expanded toward regions hosting sensitive ecosystems such as the Amazon? Important data limitations remain to answer this question, especially regarding slaughterhouses, fundamental to the beef supply chain. This paper addresses the data gap on slaughterhouse location and history and provides novel regional analysis. We map the beef industry's evolution into Brazil's interior over the last six decades and quantify changes in market concentration between 2006 and 2016. To accomplish this, we triangulated across fiscal and animal sanitation data sources to produce the first longitudinal dataset with information on the opening and closing dates, locations, and production volumes of 2602 slaughterhouses. We show the linear movement of slaughterhouses and cattle herds to the Amazon by tracking their geographical centres of gravity. We also show the clustering pattern of slaughterhouses. Until the 1960s, all the geographical clusters were located south of the capital, Brasília. By the early 2000s, clusters north of Brasília were almost as extensive. Finally, we assessed the degree of market power that the largest beefprocessing companies possess. The results indicate that market concentration increased in regions of more recent settlement further away from the coast, and that it remained relatively stable in states near the coast (Minas Gerais, São Paulo). The results shed light on the relationship between displacement toward the Amazon and Cerrado regions and economic concentration. [ABSTRACT FROM AUTHOR]

Serological tests for antibody measurement in leprosy have a series of limitations in discriminating contacts and patients. The present paper intends to evaluate if association of more than one antibody isotype in serum samples may be a useful tool in leprosy diagnosis. This study evaluated 395 leprosy contacts and 71 leprosy index cases living in endemic municipalities in Northeastern Brazil. The participants were evaluated according to their anti-phenolic glycolipid antigen-I isotype (PGL-I) profile. Serum anti-PGL-I IgM, IgG, and IgA were measured by indirect ELISA. A strong association was found for antibody positivity in MB leprosy index cases. The odds ratios were 6.11 (95% CI 3.08 – 12.16) for IgM, 3.31 (1.66 – 6.61) for IgG, and 16.97 (8.39 – 34.2) for IgA. For IgM associated with one or more isotypes, the OR was 21.0 (95% CI 10.11 – 43.64), and for IgG + IgA, the OR was 17.58 (6.23 – 49.54). The highest diagnostic sensitivity of 76.0% (95% CI 61.8 – 86.9) was observed for IgM, and the lowest value was 24.1% (13.0 – 38.2), which was observed for IgG + IgA isotypes. Regarding presumptive positive predictive values, the lowest value was obtained for IgM at 24.7% (95% CI 18.1 – 32.3), and the highest values were observed for IgM+ one or more isotypes and for IgG + IgA isotype at 60.0% (44.3 – 74.3) and 66.7% (41.0 – 86.7), respectively. The present work demonstrated that by associating two or more positive antibody isotypes, the risk of facing a real case of leprosy may increase. [ABSTRACT FROM AUTHOR]

According to the Atlas of Human Development in Brazil, the income dimension of Municipal Human Development Index (MHDI-I) is an indicator that shows the population's ability in a municipality to ensure a minimum standard of living to provide their basic needs, such as water, food and shelter. In public policy, one of the research objectives is to identify social and economic variables that are associated with this index. Due to the income inequality, evaluate these associations in quantiles, instead of the mean, could be more interest. Thus, in this paper, we develop a Bayesian variable selection in quantile regression models with hierarchical random effects. In particular, we assume a likelihood function based on the Generalized Asymmetric Laplace distribution, and a spike-and-slab prior is used to perform variable selection. The Generalized Asymmetric Laplace distribution is a more general alternative than the Asymmetric Laplace one, which is a common approach used in quantile regression under the Bayesian paradigm. The performance of the proposed method is evaluated via a comprehensive simulation study, and it is applied to the MHDI-I from municipalities located in the state of Rio de Janeiro.

This paper aims to discuss the Bayesian estimation approach for the zero-inflated cure class of models, which extends the standard cure model by accommodating zero-inflated data in the survival analysis context. A comprehensive simulation study is carried out to assess the performance of the estimation procedure. A new estimation methodology is illustrated using a real dataset related to women diagnosed with invasive cervical cancer in Brazil. [ABSTRACT FROM AUTHOR]

Over the past three decades, agrarian reform areas have transformed urban and rural spaces across Brazil. Although these areas' creation reduced inequalities and environmental problems, their residents still experience several constraints and vulnerabilities associated with water, energy, and food provision. Drawing on the water-energy-food (WEF) nexus' critical and territorial perspectives, this paper aims to better understand the agrarian reform areas' challenges in peri-urban interfaces towards social justice. We analyse a territory in the Northeast portion of the São Paulo State, where it is located the Sepé Tiaraju agrarian reform settlement in interface with two municipalities. We suggest that agrarian reform areas can activate a progressive and concrete environmental change at the local level where food is the key element to redefining the area's nexus. However, socio-political and spatial dynamics involving water and energy for the sugarcane sector, the municipal government, and tense relationships among residents around food also reproduce unequal access to resources. This paper contributes to the emerging critical literature and its efforts to politicize the nexus debate, giving more nuanced views to the complex and contradictory dynamics involving environmental problems and social justice struggles.

This paper analyses decadal climate phenomena and the phases of the Atlantic Multidecadal Oscillation (AMO) and Pacific Decadal Oscillation (PDO), and assesses the climate–water–energy nexus at the reservoir system of the São Francisco River Basin (SFRB), Brazil. This study brings a non-traditional approach focused on the link between climatic patterns and hydrological processes and their social-economic consequences, such as their effect on energy production. The methodology used data from the precipitation, natural streamflow, and AMO and PDO series. These variables were evaluated by wavelet transform analysis (WTA), flow duration curve (FDC), streamflow that is equalled or exceed ed 90% of the time (Q90), the reliability index (RI) for different demands and the hydropower generated. The results suggest that the WTA for the SFRB was more significant on the inter-annual scale, and the period with opposite phases of AMO(−) and PDO(+) showed the highest values of FDC, Q90, RI and hydropower generated simulated for the SFRB.

This paper presents a synthetic travel demand for the Greater São Paulo Metropolitan Region of Brazil, entirely based on open data and representative of the observed travel demand. The open-source and extendable pipeline creates a path from raw data to the synthetic travel demand and, further, to the downstream agent-based mobility simulation. An advantage of this approach is that it enables the reproduction of the synthetic travel demand and, therefore, provides the foundation of repeatability of downstream studies. Furthermore, as the methodology is based on open data, the study's outcomes are easily accessible to the broad research and practice-oriented community. [ABSTRACT FROM AUTHOR]

This paper investigates climate change impacts on the hydrology and water quality of Brazilian semi-arid reservoirs. An integrated approach coupling climate, hydrological and water quality models was proposed. Five general circulation models (GCMs) and two future scenarios (SSP2-4.5 and SSP5-8.5) were used for the projections. The simulations showed that uncertainty in climate forecast significantly impacted hydrological and water quality outputs. Some scenarios revealed a strong decrease in streamflow and storage volume. On the other hand, 40% of multi-GCM projections indicated reservoir eutrophication. The impacts on hydrology and water quality under SSP5-8.5 were more significant than those under SSP2-4.5. The results also indicated that drought events may be prolonged under climate change, principally at the end of the 21st century for SSP5-8.5, and may significantly increase the total phosphorus concentration. This suggests that tropical semi-arid reservoirs could be more vulnerable to eutrophication in scenarios of climate change than those in other regions. [ABSTRACT FROM AUTHOR]

Socio-hydrology has recently garnered attention as a promising research paradigm among hydrologists. In this paper, we argue that viewing the socio-hydrological systems as a network of causal factors can assist in these efforts by revealing emergent properties of socio-hydrological systems. These factors, which are neither actors nor affiliations but symbolic representations of miscellaneous phenomena, represent the key variables affecting socio-hydrological system behaviour. Despite being crucial for understanding system dynamics, these factors are not captured by most equations of coupled human–water coevolutionary models. To demonstrate our method, we use qualitative case study research to analyse the Jaguaribe Basin in Ceará State-Brazil as a network of factors, i.e. mental conceptions, and representations of water resource management experts. We show that most results are unsurprising, exhibiting expected causal relationships. However, there was at least one unexpected result, which showed that the variable "conflict" was the single most sensitive variable to systemic evolution. [ABSTRACT FROM AUTHOR]

This paper measures financial protection in health in Brazil by estimating the incidence and describes the profile of catastrophic expenditures and impoverishment due to household out-of-pocket (OOP) health spending. It uses the latest Brazilian consumption survey (POF 2017/2018) to analyze the composition of household health spending and applies two thresholds of household consumption to identify households facing catastrophic expenditures and impoverishment due to health care payments. Results show that a third of households spend more than 10% of their budget on health, and the share of households facing financial hardship is significantly higher among the Brazilian poor (37% among the bottom consumption deciles). Medicines are the main contributor to component of OOP health spending, reaching 85% of all OOP payments for the lowest consumption deciles. Households with women as household head and those with heads with more years of schooling have higher probability of incurring catastrophic health spending. Yearly, more than 10 million Brazilians are pushed into poverty due to OOP health care payments, which represents a larger percentage of individuals (4.87%) than reported globally (2.5%) or among Latin America and Caribbean countries (1.8%). Conclusions: Despite the achievements in implementing universal health coverage in Brazil, challenges remain to guarantee financial protection to its population (especially the Brazilian poor). Policies to expand access and affordability of essential medicines are key to improve financial protection in health in Brazil. [ABSTRACT FROM AUTHOR]

The association of hydrological models with remote sensing data allows the estimation of parameters that cannot be easily measured in situ, especially in regions with poor monitoring networks. In this paper, a distributed hydrological energy water balance model (FEST-EWB) was calibrated and validated in a basin located in a climate transition zone between a semi-arid region and the humid Atlantic Forest, in Brazil. Land surface temperature (LST) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) were used to calibrate the model, that solves the system of energy and mass balance equations as a function of the representative equilibrium temperature. For validation, soil moisture and LST data collected in situ were used. The model presented good performance for the simulation of the variables studied in the basin, even with reduced availability of MODIS data due to cloud coverage, allowing the use of FEST-EWB in areas with these characteristics, which are common in many regions of the world.

This paper applies David Lowenthal's 1968 Geographical Review article "The American Scene" and John Dos Passos' 1963 travelogue Brazil on the Move to develop a notion of the Brazilian scene. It argues for the importance of "scene" as a concept in geographic inquiry and the relevance of Brazil to concerns across the discipline. Scene matters to geographers because it provides immense pedagogical value in explaining the character and most important features of a place. As a demographic and socioeconomic "microcosm of the world," Brazil is fertile ground for constructing a theory of scene. Three interrelated concepts are integral to the Brazilian scene: ufanismo (pride in abundance of land and natural resources), a belief in the promise of the future, and movement inward from the Atlantic. A close reading of Brazil on the Move advances the concept of scene beyond the "long succession of idealized images and visual stereotypes" posed by Lowenthal, and toward including visions that better account for issues of contemporary interest.

This paper presents the results of a combined experimental and theoretical study of the interfacial and mechanical properties of epoxy/clay composites coatings on a mild steel substrate. This was studied using nano-indentation and Brazil Disk techniques to determine the Young's moduli, hardness values and mode mixity characteristics of the composite coatings. The Young's moduli of the reinforced composites comprising 1, 3, and 5 wt. % of montmorillonite clay particles are shown to improve, respectively, by about 23%, 58%, and 50% while the respective hardness values increased by about 46%, 80%, and 88%, relative to those of pristine epoxy. The measured mechanical properties have also shown to compare favorably with predictions from composite theories (rule-of-mixture and shear lag theories). The interfacial toughness between X65 steel and the epoxy/clay coatings increases with increasing mode mixity. This is associated with crack-tip shielding by crack deflection and crack bridging. The trends in the measured mode-mixity dependence of the interfacial fracture toughness values are consistent with predictions from the simplified zone, normal zone, and row models (at lower mode mixity). The insights from the observations and the measured crack profiles are incorporated into zone and row models for the estimation of crack-tip shielding. The implications of the results are discussed for the design of epoxy/clay composites with attractive combinations of mechanical properties. [ABSTRACT FROM AUTHOR]

This article analyses the interregional linkages and the relative intensity of CO2 emissions embedded into domestic and global value chains from Brazilian states. An extended environmentally interregional input-output model (EEIIO) was applied to measure the bilateral trade in value-added (TiVA) and the total implicit emissions trade (TTE). The results reveal unbalanced pollution patterns in space. Few manufacturing hubs in core Brazilian states (mainly São Paulo and Rio de Janeiro) are net importers of intensive greenhouse gas (GHG) inputs from peripheries, implying an environmental responsibility driven by networks' governance and relative position. By recognizing the role that multiscalar integration plays in implicit CO2 in both production and trade, it is possible to build local strategies to reduce sustainable spatial gaps.

The city of São Carlos, state of São Paulo, Brazil, has a historical coexistence between society and floods. Unplanned urbanization in this area is a representative feature of how Brazilian cities have developed, undermining the impact of natural hazards. The Gregório Creek catchment is an enigma of complex dynamics concerning the relationship between humans and water in Brazilian cities. Our hypothesis is that social memory of floods can improve future resilience. In this paper we analyse flood risk dynamics in a small urban catchment, identify the impacts of social memory on building resilience and propose measures to reduce the risk of floods. We applied a socio-hydrological model using data collected from newspapers from 1940 to 2018. The model was able to elucidate human–water processes in the catchment and the historical source data proved to be a useful tool to fill gaps in the data in small urban basins.

Lactifluus (Russulaceae) is a genus of ectomycorrhizal fungi, comprising mostly tropical milkcaps with more than 150 described species. In Brazil 24 milkcap species are known, but only three of these are described from the north-eastern region. The north east of Brazil is composed of different types of habitats, namely Atlantic Forest, part of the Cerrado ecoregions and the Caatinga Domain. From the semiarid Caatinga Domain, Lf. caatingae is described in this paper as a new species, using morphological and molecular data. The new species is characterised by the rusty brown to brownish orange basidiomes, subglobose to broadly ellipsoid, rarely globose basidiospores with verrucose ornamentation composed of warts up to 0.6 µm, that are interconnected by fine lines forming a complete reticulum, and the lampropalisade structure of the pileipellis. Phylogenetic analysis shows that Lf. caatingae belongs to L. subg. Lactariopsis, more specifically to an unnamed clade containing exclusively Neotropical representatives. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate whether the so-called crowding in effects of complementarity or the crowding out effects of substitution occurred between public investment and private investment in Brazil from 1982 to 2013. This will be carried out through a theoretical debate on the investment general dynamics and an econometric analysis of vector error correction (VEC) model for the Brazilian case. The trajectory of the Brazilian economy and the empirical results show the presence of crowding in between public and private investments in the period, in accordance with the Post-Keynesian approaches. The crowding in is justified by the effects on demand via the Keynesian multiplier and via the expansion of the domestic market (particularly provided by infrastructure) and by the effects on the supply of private capital through the reduction of production costs, the increase in productivity, and through structural changes facilitated by public policy. Complementarity with regard to both the investments of the public administration and of federal government-owned/controlled enterprises is confirmed. Furthermore, a significant causal relationship is observed between public investment and the output of industrial manufacturing, which, from the structuralist perspective, is a sector that is considered a driving force of the economy. The special contributions of this paper are its time series for public investment and the variety of models that show crowding in between public and private investment. [ABSTRACT FROM AUTHOR]

By addressing the growth of digital platforms in Brazil over the past decade, as well as the search for regulation aiming at improving digital workers' conditions, this article discusses regulatory challenges in the face of these companies' increasing economic and political power. With the adoption of the transactional approach of John R. Commons, we discuss the stages and consequences of the spread of digital platforms, highlighting the emergence of new conflicts in driver-platforms and driver-state transactions, thus calling for regulation; as well as the political obstacles of regulation, considering platforms economic power and worker's expectation about their activities under regulation. We argue that these features challenge the regulatory efforts aimed at achieving reasonableness in digital labor transactions, by reducing public pressure towards "better" practices, such as improved working conditions, wages, and management.

This study intends to examine the roots of Original Institutional Economics (OIE) in Brazil. We rely on two methodologies to analyze the dissemination of OIE in Brazil: a bibliometric study, which identifies key Brazilian authors who published their studies in the Journal of Economic Issues (JEI); and an analysis of academic curriculum vitae (CVs) through an online compilation of Brazilian researchers' CVs, the Lattes Platform, where it is possible to identify researchers by field. After identifying the Brazilian institutionalists, we study their writings, professor–student relationship, co- authorship, and teaching. We identify three groups of Brazilian institutionalists: (1) a heterogeneous group in São Paulo, (2) a group in Paraná that is concentrated at the same university, and (3) a cohesive group in Rio Grande do Sul.

Brazil has some of the largest rivers in the world and has the second greatest flood loss potential among the emergent countries. Despite that, flood studies in this area are still scarce. In this paper, we used flood seasonality and trend analysis at the annual and seasonal scales in order to describe flood regimes and changes across the whole of Brazil in the period 1976–2015. We identified a strong seasonality of floods and a well-defined spatio-temporal pattern for flood occurrence. There are positive trends in the frequency and magnitude of floods in the North, South and parts of Southeast Brazil; and negative trends in the North-east and the remainder of Southeast Brazil. Trends in the magnitude (frequency) were predominant in the winter (summer). Overall, floods are becoming more frequent and intense in Brazilian regions characterized by wet conditions, and less frequent and intense in drier regions. [ABSTRACT FROM AUTHOR]

Brazil is a middle-income country with universal maternity care, mostly by doctors. The experience of normal birth often includes rigid routines, aggressive interventions, and abusive, disrespectful treatment. In Brazil, this has been referred to as dehumanised care and, more recently, as obstetric violence. Since the early 1990s, social movements (SM) have struggled to change practices, public policies and provider training. The aim of this paper is to describe and analyse the role of SM in promoting change in maternity care, and in provider training. In this integrative review using a gender-oriented approach, we searched the Scielo database and the Ministry of Health’s (MofH) publications and edicts for institutional and research papers on SM initiatives addressing disrespect and abuse in the last 25 years (1993-2018) in Brazil, and their impact on public policies and training programmes. We analyse these groups of interrelated initiatives: (1) political actions of SM resulting in changes in public policies and legislation; (2) events organised by SM for diffusion of information to the public; (3) MofH policies to humanise childbirth with participation of SM; and (4) initiatives to change providers’ training, including legal actions based on obstetric violence reports. To promote real change in maternity care, the progression of policies and enabling environment of laws, regulations, and broad dissemination of information, need to go hand in hand with changes in all health providers’ training - including a solid base in ethics, gender and human rights.

Teaching Impact Assessment (IA) is both important and challenging. In this context, international literature presents a set of Best Practice Principles for IA Teaching and Training. This paper proposes and applies a framework of 14 indicators to analyse the content of IA teaching. It focuses on the Brazilian Environmental Engineering Programs, and the methodological process involved examining the literature as well as content analysis. The framework application showed to be practical and objective. Results indicate that the capacity to incorporate the specifics of the IA system is a strength of IA teaching in Brazil. On the other hand, the results highlight many weaknesses, e.g. the focus on teaching only IA applied to projects (in spite of the many IA types present in IA literature and international practice), focus on impact assessment statement (instead of the whole IA process) and gaps related to study of alternatives, cumulative impacts and public participation. Suggestions to improve IA teaching in Brazil include presenting IA as a process. [ABSTRACT FROM AUTHOR]

This study aims to analyze the impact of Covid-19 on the female's labor force participation (LFP) probability in Brazil in 2020. We found through the probit model that females are about 7 percentage points less likely to participate in the labor force than males. Covid-19 and layoffs decrease by about 7 and 30 percentage points the women's LFP probability, respectively. An additional year of schooling increases female's LFP probability by 14 percentage points. These results are statistically significant at 1%. However, Covid-19-gender interaction term coefficient is not significant. We suggest a rich agenda for women's jobs opportunities in developing countries. [ABSTRACT FROM AUTHOR]

The vulnerability of the Amazon has widely increased with the COVID-19 global pandemic and with the dismantlement of environmental protection policies in Brazil during the Bolsonaro administration. By contrast, local initiatives focusing on sustainable production, conservation, enhancing local people's quality of life, and supporting a more inclusive economy have emerged throughout the region and are building resilience in face of these disruptions. They represent seeds for transformation towards more sustainable trajectories from the ground up. In this context, women play a significant role, but their actions and voices are poorly understood, studied, or even considered. In this article, we use a novel approach to engage and highlight women's experiences by connecting decolonial and process-relational perspectives. Decolonial and process-relational thinking are closely linked in many ways, including in that they embrace difference as a mode of experiencing social-ecological relations. One particular aspect of this link is the shared focus on liminal thinking or thinking from the borders, what we call 'betweenness'. In our decolonial praxis, we highlight women's perspectives on their particular and diverse ways of life in the Amazon as they confront diverse pressures. To this end, we collaborated with 39 women from Santarém and neighboring towns in western Pará through participant observation, semi-structured interviews and facilitated dialogues. We discuss their perspectives on regional transformation, particularly the expansion of large-scale agribusiness around rural communities, and their understanding and responses to these changes. We reflect on the mutual learning experience resulting from the transdisciplinary engagement between researchers and collaborators. [ABSTRACT FROM AUTHOR]

The inclusion of Sustainable Development Goals (SDGs) in climate mitigation pathways is critical and can be reached by assessing their consequences through the deployment of appropriate indicators to that end. Integrated Assessment Models (IAMs) are important tools for understanding possible impacts caused by adopting new policies. We investigate terrestrial biodiversity trends (life on land: SDG 15) for three different climate mitigation scenarios for Brazil: (1) A scenario compatible with a world that maintains its current policies with current deforestation rates in the Amazon and the Cerrado biomes; (2) A scenario in which Brazil fulfils its Nationally Determined Contribution (NDC); and (3) A scenario compatible with a world that limits warming to 1.5°C. We use the Brazilian Land-Use and Energy System model (BLUES), a national IAM, to show the implications of the transitions involved in the above-mentioned scenarios for the country up to 2050. We conduct a post-processing analysis using consolidated biodiversity indicators to emphasize how different IAM greenhouse gas (GHG) emissions mitigation solutions present distinct positive and negative potential impacts on biodiversity in Brazil. However, our analysis does not consider the impacts associated with climate change, but only the risks imposed by mitigation policies. Our results indicate that biodiversity loss decreases in the scenarios from (1) to (3), implying that stronger climate change mitigation actions could result in smaller biodiversity losses. We conclude that Brazil has the opportunity to align its biodiversity and climate goals through nature-based solutions (NBS), such as forest conservation, restoration, pasture recovery, and the use of crop-pasture and agroforestry systems.

Domestic cats (Felis catus Linnaeus, 1758) can interact with and cause several negative impacts upon wildlife if unconstrained by their owners. These impacts occur especially because of their innate predatory behavior and, usually the lack of any natural predators, as well as due to their high abundances relative to native carnivores. Although these impacts are well studied in temperate countries, there are but a few records of species used as prey by these carnivores in Brazil. Here, we expand the knowledge of native species preyed upon by domestic cats in Brazil by presenting new records of this predator-prey interaction and reviewing records in the literature. Predation events were recorded through opportunistic encounters between 2016 and 2022. We recorded the predation of 14 native terrestrial vertebrate species (reptiles, amphibians, birds, and mammals) from the Cerrado and Atlantic Forest biomes. Our literature review recovered predation events by cats in the two aforementioned biomes plus in the Amazonia. Our results increase to 48 the number of wild species preyed upon by domestic cats in Brazil, which is probably an underestimation, as this number is much higher in other countries of comparable land size and species diversity. We suggest that cat population control measures should be carried out, especially in protected areas. [ABSTRACT FROM AUTHOR]

Background: Radiology is a useful tool for diagnosis and intervention in medical practice, and all the components within the teaching-learning process of this subject during undergraduate studies influence successful knowledge application. Objective: This study aimed to describe the level of knowledge in radiology of students in the last two years of medical school and curricular characteristics of their courses in seven Latin American countries. Methods: A multicenter cross-sectional study was carried out on medical students of 7 Latin American countries (Bolivia, Brazil, Colombia, Ecuador, Mexico, Paraguay, and Peru) in their final two years of medical school, using an online questionnaire validated by experts and adapted for each country that assessed knowledge and curricular characteristics in radiology subject. Scores were assigned according to the number of correct answers for the knowledge test. The T-test, and regression analysis with one-way ANOVA were used to search for relationships between the level of knowledge and other variables. Results: A total of 1514 medical students participated in this study. All countries had similar participation (n > 200); most participants were women 57.8%. The country with the highest knowledge score was Brazil. Male, sixth year (internship) and from public universities students had higher knowledge score (n < 0.05). Participants, who considered radiology more important, and who reported higher compliance with teaching staff with the proposed syllabus, and programmed classes, obtained better scores (n < 0.05). Conclusions: Latin American medical students included in this study have a regular overall level of knowledge of Radiology, apparently influenced by curricular differences such as class and academic program compliance. Efforts to better understand and improve academic training are indispensable. Limitations: The study was subject to selection bias determined by non-probability convenience sampling. The questionnaire assessed only theoretical knowledge and the evaluation system was designed by the investigators. [ABSTRACT FROM AUTHOR]

A new species of annelid, Alitta yarae sp. nov., is described from material collected in southern Brazil. This species was collected mostly from fishing buoys but also in muddy substrates of the following estuaries: Paraná Estuary Complex, Guaratuba, and Babitonga Bay. Alitta yarae sp. nov. belongs to a group of species with pennant-shaped posterior dorsal ligules. The most similar species of this group is A. succinea, which shares glandular structures from posterior dorsal ligules on lower edge only and having yellow-amber mandibles. However, the two species differ in the extension of the bare space between areas VI and VII-VIII, which is reduced in A. yarae sp. nov. and wider in A. succinea (respectively shorter than or equal to the palpophore), and the paragnath arrangement. Molecular analysis recovered ~20% genetic distance from the closest species A. succinea and no pattern of segregation among the estuaries studied. Finally, both the morphological and the molecular analyses strongly support the designation of a new species. [ABSTRACT FROM AUTHOR]

Background: Since the publication of the reports by the Commission on Social Determinants of Health (CSDH), many research papers have documented inequities, explaining causal pathways in order to inform policy and programmatic decision-making. At the international level, the sustainable development goals (SDGs) reflect an attempt to bring together these themes and the complexities involved in defining a comprehensive development framework. However, to date, much less has been done to address the monitoring challenges, that is, how data generation, analysis and use are to become routine tasks. Objective: To test proposed indicators of social determinants of health (SDH), gender, equity, and human rights with respect to their relevance in tracking progress in universal health coverage and population health (level and distribution). Design: In an attempt to explore these monitoring challenges, indicators covering a wide range of social determinants were tested in four country case studies (Bangladesh, Brazil, South Africa, and Vietnam) for their technical feasibility, reliability, and validity, and their communicability and usefulness to policy-makers. Twelve thematic domains with 20 core indicators covering different aspects of equity, human rights, gender, and SDH were tested through a review of data sources, descriptive analyses, key informant interviews, and focus group discussions. To test the communicability and usefulness of the domains, domain narratives that explained the causal pathways were presented to policy-makers, managers, the media, and civil society leaders. Results: For most countries, monitoring is possible, as some data were available for most of the core indicators. However, a qualitative assessment showed that technical feasibility, reliability, and validity varied across indicators and countries. Producing understandable and useful information proved challenging, and particularly so in translating indicator definitions and data into meaningful lay and managerial narratives, and effectively communicating links to health and ways in which the information could improve decision-making. Conclusions: This exercise revealed that for monitoring to produce reliable data collection, analysis, and discourse, it will need to be adapted to each national context and institutionalised into national systems. This will require that capacities and resources for this and subsequent communication of results are increased across countries for both national and international monitoring, including the successful implementation of the SDGs.

Empirical studies confirm that the impact of capital account regulation (CAR) is highly case-specific, which underlines the need to identify the determinants of CAR effectiveness in greater depth. Coming from a political economy perspective, this article aims to contribute to this subject by comparing three experiences of intense regulation: Brazil (2008-2013), Peru (2008-2013), and Iceland (2008-2017). The main result encountered is that the bargaining power of the different sectors involved in regulation represents a crucial factor in explaining the impact of this policy. Furthermore, domestic banks play an important role in the effectiveness of capital account regulation. [ABSTRACT FROM AUTHOR]

Early assessment of environmental issues is key for sound decision-making about licensing of offshore oil and gas exploration sites. In this paper, we recall the historical background of such early assessments in Brazil showing that a simple consultation process in place for the last 15 years was able to steer oil and gas exploration away from sensitive areas. A more structured SEA-type instrument was designed in 2012, but its actual contribution to the effectiveness of early assessments remains to be seen as the first assessment reports are still to be delivered. Recent changes in the institutional and political context in Brazil have enabled the new government to ignore both the established consultation process and the ongoing SEA-type process. This shift of orientation led to the inclusion of environmentally sensitive areas in bidding rounds in 2019. Following this government decision, various initiatives to preserve the recommendations from the previous consultation process have illustrated the relevance of environmental/impact assessment not only to ease decision-making processes but also as a tool to safeguard environmental protection.

Large-scale photovoltaic (LSPV) may cause significant changes in the environment and lead to detrimental impacts on the natural and anthropic environments. First, this paper reviews the scholarly literature to collect data regarding the different environmental impacts occurring during LSPV installation and operation. Secondly, methods used in the Environmental Impact Assessment (EIA) for LSPV are evaluated through a sample of 20 EIAs. This shows that there are flaws in the methodology used in the EIAs that support environmental licensing of LSPV. In this context, this work proposes a multicriteria approach that aims to convey the main environmental and socio-economic aspects of LSPV and assess impact magnitude and importance. The method is built on the needs to improve EIA for the licensing of solar projects in Brazil. The model offers a structured approach that incorporates detailed criteria that reflect direct and indirect impacts of both terrestrial and floating PV and is designed to provide the assessment magnitude and estimate scenarios according to different stakeholder's views.

The objective of this paper is to analyze a tiering scoping approach developed to identify critical multidimensional sustainability issues and impacts of a large infrastructure project: the land transport project linking northern Brazil with a new port on Guyana's coast. The Inter-American Development Bank awarded a technical assignment to develop the terms of reference of a country environmental assessment, a strategic environmental and social assessment and an environmental and social impact assessment of the project(s). The complexity of the issues at stake lead to the design of a tiered assessment process supported by wide-ranging participative sessions involving 170 individuals from Guyana and Brazil and from diverse sectors. The process identified ex ante conditionalities, critical factors for decision-making and valued socioenvironmental and governance components. Such complex and determinant planning initiatives for the future of a country need to be supported by comprehensive, well-sequenced scoping processes. [ABSTRACT FROM AUTHOR]

Empirical research dedicated to Strategic Environmental Assessment (SEA) is mostly grounded on SEA systems guided by legal requirements, clearly stated procedures and systematic use of SEA to policy- and plan-making. Nevertheless, a considerable parcel of SEA practice is currently occurring in countries with no specific legislation or guidance to be followed, i.e. non-regulated SEA systems. Therefore, it is important to understand how SEA is performing in these countries and to establish whether related SEA systems are subject to the same premises and perspectives of effectiveness that have been reported in literature so far. The paper provides a comprehensive analysis of the state-of-practice in Brazil, based on best practice analysis of SEA reports and interviews, reporting empirical evidence regarding the use of SEA and its related timing, procedural performance and key players involved. Main findings reveal an isolated instrument, embroidered in a disperse and unclear framework, poorly coordinated and highly sensitive to circumstances. Provision of a structured system, indicating clear purposes of SEA, systematic procedures and stakeholder's responsibilities are suggested as potentially relevant measures to balance current system's flexibility, thus fostering SEA effectiveness.

By systemizing a typology from John R. Commons and John B. Andrews' discussion about collective bargaining and the attitudes of governments towards labor unions, we present in this article the use of this categorization to investigate the vicissitudes of unionism in Brazil. We do so by analyzing the interaction between the government and labor unions in two different inflection points in Brazil's labor law history: (i) the Vargas Era (1930--1945) and (ii) the Labor Reform of 2017. Our conclusions relate these periods to the attitudes of "intervention" and "tolerance," respectively, pointing now to aspects of increasing opposition towards collective action as the economic crisis and unemployment deepen, and new reforms take place.

This article presents a new approach for building robust portfolios based on stochastic efficiency analysis, by using the Chance Constrained Data Envelopment Analysis (CCDEA) model and periods of market downturn, i.e. worst-state market. The model is able to accommodate investors who exhibit different risk behaviors and the empirical analysis is done on assets traded on the Brazil Stock Exchange, B3 (Brasil, Bolsa, Balcão). The results confirm that the proposed model achieved portfolios that at the same time reduced systematic risk and maximized portfolio returns when working with worse market state data and higher levels of risk aversion. A higher level of risk aversion also led to better risk-return ratios, which can be seen in higher Sharpe ratio values. [ABSTRACT FROM AUTHOR]

The world today is an urban world. While rural to urban migration has contributed significantly to the increased urbanization of the globe, that process has not always been as clear and permanent as it appears. In this paper we report on the migration of smallholders to peri-urban interface ( PUI) zones in western Pará state, Brazil. We found that rural-urban migrants were constrained by their lack of marketable skills and as a consequence had few job prospects and experienced a low quality of life in the cities to which they had migrated. This led them to resettle in places at the PUI where they have the ability to supplement limited wages with more familiar subsistence activities, which reflected cultural identity and rural antecedents while enjoying a higher quality of life. The recent implementation in Brazil of a variety of conditional cash-transfer programs has added to the attractiveness of peri-urban places and contributes to a regional shift to livelihoods based on a combination of agriculture and extractivism supplemented by support from federal assistance programs.

Within the ample body of literature devoted to strategic environmental assessment (SEA) outcomes and the assessment of its effectiveness, it is accepted that the performance of SEA systems is influenced by contextual aspects. Procedural aspects, objectives, guidance, approach, timing, amongst others, are reported as key components of the different dimensions of SEA effectiveness but their linkage to SEA outcomes is yet to be adequately investigated. In this paper, contextual aspects and related outcomes of a non-mandatory SEA system were identified through systematic literature review and personal interviews with key actors of SEA, aiming at the identification of the influence of contextual factors on SEA effectiveness. The findings indicate three main aspects that may explain the lengthy process of introduction of SEA in plan- and policy-making in the country: (i) lack of proper SEA legislation, (ii) the influence of Environmental Impact Assessment practice and (iii) the influence of the environmental licensing culture. Nevertheless, SEA contributes to improving communication between stakeholders along the planning process and to providing a better level of information for lower tiers of decision-making. In spite of the minor influences on the nature of the strategic action, valuable lessons credited to SEA have been learnt. [ABSTRACT FROM AUTHOR]

Land use is a driver for hydrological and soil erosion responses at the watershed scale. This study aimed to assess the hydrological and soil erosion processes in small watersheds under three different land uses, at three time scales. We investigated four small watersheds in southern Brazil: Agricultural North watershed (ANW), Agricultural South watershed (ASW), Eucalyptus watershed (EW), and Grassland watershed (GW). The SWAT (Soil and Water Assessment Tool) model was used to simulate streamflow (SF) and sediment yield (SY) at monthly, daily and hourly time scales. EW had the lowest SF and SY, whereas ANW showed the highest SY with an increase of 90% and ASW had the highest SF with an increase of 70%. The SWAT model had a satisfactory performance in all time scales and watersheds for SF and SY (NSE and R2 ≥ 0.3 and Pbias ≤ ± 39%). Overall, land use has a major impact on hydrological and soil erosion responses, and the magnitude of these processes depends on the time scale. [ABSTRACT FROM AUTHOR]

The world financial crisis of the late 2000s was for some the dawn of a new era in which state currency monopolies would be replaced by privately-issued digital currencies following strict rules of supply growth. Rather than trust big government and big banks with our money, cryptocurrencies would allow us to "trust the code" and the "mathematical structure" of blockchain technologies. In Brazil, as elsewhere, this neoliberal techno-utopia has not arisen. Though their use as speculative assets has increased, cryptocurrencies have not become a popular means of payment. The use of electronic money, on the other hand, issued by novel corporate entities called payment institutions, is now commonplace. Unlike cryptocurrencies, digital banking and electronic money in Brazil rest on a solid legal and institutional framework designed to incorporate them into the payments system. Digital banks enjoy most of the privileges bestowed upon traditional banks, making it possible for customers to use digital accounts in the same manner as a traditional checking account. In short, digital banks have become privileged members of Brazil's state-led "pay community" and this is why they have flourished. Even in the digital era, money is a creature of the state.

Despite being adopted worldwide, environmental impact assessment (EIA) is under pressure in many countries, while perceived (rightly or wrongly) as an ineffective and inefficient process. Strategic environmental assessment (SEA) is thought to help address some of EIA’s shortcomings, but it is absent in many jurisdictions and sectors. In this paper, we argue that multi-project EIA can, in some contexts, simultaneously deliver greater effectiveness and process streamlining. To illustrate our claim, we present a case study from offshore petroleum production in Brazil, where the development of the pre-salt giant reserves is being licensed through a multi-project EIA approach, in a non-SEA planning environment. The analysis provides interesting insights on the strengths and challenges of that strategy, focusing on five aspects of practice: cumulative impacts, efficiency, approach to authorizations, follow-up and political issues. Proper scoping was found to be essential to consistent EIA processes and shorter review times. Finally, we suggest that multi-project EIA approach should be revisited by practitioners and regulators to identify opportunities for deployment, especially in jurisdictions where strategic assessments are not in place.

This study investigates the sensitivity and uncertainty of evaporation assessment in a tropical reservoir in northeastern Brazil. For this purpose, four approaches were used: Penman, a Dalton-modified equation, a pressure meter and a novel acoustic sensor. The main objective is to evaluate whether sensors can be employed to adequately assess lake evaporation. The sensors were installed in floating pans and the equations are based on variables collected from a raft. The wind-inducted waves in the reservoir often disturbed the measurements using both pressure (uncertainty of ± 0.6 mm) and acoustic (uncertainty of ± 0.1 mm) sensors, causing flaws and affecting continuous monitoring. The modified Dalton model, based on data collected with a floating station, estimated values over three-hour courses of evaporation similar to those measured by the pressure meter. These findings are important contributions to an accurate monitoring of water losses through evaporation and reservoir operation, particularly in dry regions. [ABSTRACT FROM AUTHOR]

Have Brazil's capital flows management measures (CFMs) changed after the Global Financial Crisis (GFC)? This article explains Brazil's CFMs after the GFC as part of a (failed) attempt to gradually move away from embedded neoliberalism. It proposes a Polanyian approach that captures both the change (emphasized by the policy space approach) and the continuity (underscored by the scalar-relational and financialization approaches) underlying Brazil's CFMs after the GFC. It argues that the change stems from the conflict between different political economy coalitions, while the continuity is rooted in the shared acceptance of major objectives of neoliberalism—capital mobility and financial integration.

Based on the Conservation of Resources Theory, this longitudinal study analyzes the contribution of organizational affective commitment during the preparation phase of a peacekeeping mission (T1) to explain the well-being of soldiers during that mission (T2). A sample of 409 Brazilian army participants in the MINUSTAH (United Nations Stabilization Mission in Haiti) was used in two waves -- preparation of the troops in Brazil, and their deployment in Haitian territory. The data analysis was performed using structural equation modeling. The results supported organizational affective commitment during the preparation phase (T1) positively predicting the general well-being (perception of health and general satisfaction with life) of these soldiers during the deployment phase (T2). The workplace well-being (i.e. work engagement) of these peacekeepers was also found to mediate this relationship. Theoretical and practical implications are discussed, and limitations and suggestions for future research are presented. [ABSTRACT FROM AUTHOR]
