The contribution of this paper is to discuss the particularities of financialisation in peripheral economies, emphasising the channels through which financialisation contributes to redefining their trajectory of structural change. This paper has, as a reference, the structural regression of the Brazilian case, which is characterised by the deindustrialisation and trade specialisation marked by export reprimarisation. The aspects covered are the financialisation of non-financial corporations, of the exchange rate and of the determination of the commodity prices, which are associated with the Dutch disease.

The paper examines the determinants of rentier income in contemporary financialised capitalist economies by analysing the case of Brazil. It argues that different drivers of rentier income may have comparable potential to channel a substantial share of aggregate income to asset owners. The paper estimates an expanded functional income distribution for Brazil for the period between 2000 and 2019, which distinguishes between rentier income, wages, profits of enterprise and government income. In the last two decades, the share of rentier income in Brazilian GDP has fluctuated around an approximately stable trend even though its composition has changed profoundly. The estimation presented allows for an analysis of the role played by financial expropriation (i.e. interest payments out of wage income) in this expanded functional income distribution, which points to alternative results concerning the recent trajectory of the wage share of income and of the distributive conflict.

In Brazil, many D/deaf persons use the country's official sign language, Libras, to communicate and develop a sociocultural identity. For most Libras users, learning how to read and write in Portuguese, the country's official written language, is a challenge. To address the problem, we present a framework for codesigning accessible technologies for and with D/deaf persons. In this paper, we describe and analyze the case study of an environment to support the teaching–learning process of written Portuguese as a second language. Our main contribution is the documented experiences of codesigning with D/deaf and hearing participants, through individual and collaborative work, which increased confidence and creativity and enhanced empathy through sharing own experiences. Various types of participants were included through the entire framework process, and important values were reinforced, such as ownership and self-determination. [ABSTRACT FROM AUTHOR]

Santa Catarina is a small, developed, and relatively safe state in South Brazil. Despite having positive social economic indicators, it still faces multiple challenges regarding forensic practices for personal identification. The objective of this paper is to discuss the recent advances and current challenges in the region, from the perspectives of anthropological and dental postmortem human identification, missing persons, and disaster victim identification (DVI) from 2019 to 2021. The recent creation of a Forensic Anthropology Sector (SAF) in the state's official forensic institution (Polícia Científica—PCI) has significantly improved identification of unidentified remains and optimised resources available for DNA analysis. However, SAF is still quite understaffed, which negatively affects the recovery of skeletal material, its preparation, and the time needed for filing reports. Santa Catarina has passed legislation for missing persons in 2015, 4 years prior to the sanction of federal laws implementing the national policy for the disappeared. Nonetheless, a lack of integration between stakeholders remains a problem that PCI has tried to circumvent with the Conecta Programme, a multidisciplinary and integrated initiative between families of the missing persons, police agencies, and the Public Ministry. The programme aims to collect not only reference DNA samples, but also relevant anthropological and dental data. It also offers facial progression services in cases of disappearances that occurred many years ago. Despite a history of disasters in the state, PCI still needs to implement international DVI standards at an institutional level. Recent training on Phase 1 DVI procedures, integrated with other responding institutions, indicates better preparation for future disasters. There are many challenges ahead for Santa Catarina's forensic institution and professionals that have yet to be addressed, but the overall situation on routine personal identification, missing persons initiatives, and DVI has improved over the last 2 years. Over the last 2 years, the Santa Catarina state in South Brazil has experienced significant improvements in personal identification procedures, missing persons policies, and DVI capacitation. The creation of the Forensic Anthropology Sector (SAF) in October 2020 (which also houses dental postmortem examinations) in the state's official forensic institution (PCI) has established an alternative for quick, low-cost personal identification in cases of unidentified remains, in addition to optimising resources available to DNA analysis. PCI's Programme Conecta has been locally promoting improved integration of missing persons' stakeholders with the newly instituted national policy for the disappeared in Brazil. Despite having a history of disasters and a recent first integrated training on Phase 1 DVI procedures, Santa Catarina state still needs to implement DVI procedures at an institutional level.

The empirical investigation on countries' long-term growth usually relies on growth accounting methods, which are based on a supply-led approach, where factors accumulation are the main countries' growth constraints. This approach, however, ignores the importance of effective demand in explaining the long-term dynamics. Conversely, Keynesians stress the centrality of effective demand to explain why some countries present high growth rates for prolonged periods and others do not. They account for different views on the determinants of demand growth, such as exports dynamics, income distribution and public investment. The aim of the paper is twofold. Firstly, it extends the SDA method – a method that allows us to identify sources of changes in input–output matrices – to account for endogenous consumption and import-substitution impacts, and, secondly, it applies this method to understand the Brazilian slowdown in the 2010s. Based on a Miyazawa–Leontief framework, it is possible to identify the importance of each of the demand factors in explaining countries' growth, considering both the autonomous sources of demand and their potential to spread through the economy via their multiplier effects. The application of this extension to investigate the Brazilian slowdown in the 2010s shows the importance of natural resource exports, public investment and absorption of domestic demand in different sub-periods. Based on these findings, we discuss the possibility of Brazil to restore its growth potential through specific demand stimulus, such as infrastructure investments. [ABSTRACT FROM AUTHOR]

The coronavirus disease 2019 (COVID-19) pandemic posed several challenges to the Brazilian health system, among them the general context of ambiguity and uncertainty and the conflicting positioning of the government in power concerning scientific advice resources. Different aspects can be analyzed to explore the dynamics of strengthening and resilience of the system. This paper focuses on its analytical capacity, examining how it was developed and recently challenged. The investigation employed survey data, analysis of official documents and newspaper articles, and in-depth interviews with specialists and federal bureaucrats. The research shows the magnitude and relevance of that dimension of policy capacity in the federal health system and how it was crucial to the resilience of the system in defining the directions of the fight against COVID-19 in Brazil, although scientific-based recommendations were rejected by political leaders.

This article investigates the existence of a link between financial cycles and fiscal cycles, and discusses possible policy implications for developing and emerging economies (DEEs). It empirically analyses the impact of financial cycle shocks on the short-term dynamics of Brazil's fiscal policy by estimating a vector autoregressive (VAR) model for the period 1997–2018. The results indicate that financial cycles have pro-cyclical effects on the fiscal policy. This suggests that a fiscal policy should consider not only the cyclical behaviour of the output, but also its role in minimising financial factors. By explicitly linking Brazil's fiscal performance with Brazil's higher vulnerability to the financial cycle, this article adds to the literature that strives to understand the policy implications of the financialisation process in DEEs. It also contributes to the more general empirical literature on DEEs' fiscal dynamics. [ABSTRACT FROM AUTHOR]

This paper contributes to discussions about subnational responses to the coronavirus disease (COVID-19) pandemic in federal countries. In the scholarship on federalism and public policy, few studies seek to understand the factors that shape subnational differences in welfare levels. This article seeks to better understand this issue in Brazil by exploring how, in a context with little national-level coordination, subnational governments tackle the inequalities exacerbated by the COVID-19 pandemic. This study analyzes two social policy areas with distinct national-level coordination mechanisms and federal responsibilities: social assistance and education. Two multi-level cases are examined: the states of Amazonas and São Paulo and the cities of Manaus and São Paulo. This analysis relies on quantitative data, mainly social indicators, and qualitative data collected through documents and in-depth interviews. Social assistance and education policy actors in Amazonas and São Paulo faced at times significant obstacles adapting and/or creating policies to tackle inequalities, resulting in a fend-foryourself federalism and fragmented subnational policies. Differences in subnational responses can be explained by distinct policy legacies and previous capacity, which were key in organizing a useful response to the pandemic. However, to fully explain subnational responses, the role of actors within institutional contexts must also be taken into account. In social assistance, shared responsibilities among different levels of government led to competition and credit claiming dynamics, reinforcing fragmented and uncoordinated responses. In education, decentralization and more stable funding allowed political leadership to activate and mobilize subnational capacities and other actors at the subnational level, producing more sustainable responses.

This article provides an overview of beef production and carcass evaluation in Brazil. It highlights Brazil's significant role in the global beef market and its record-breaking export revenues. However, Brazil lacks a national carcass grading system, with slaughterhouses using their own metrics to meet market demands. The current standard for carcass classification in Brazil is based on dentition, gender, carcass weight, and subcutaneous/external fat scores. The article also discusses beef cattle production systems, market statistics, and the need for a new Brazilian classification and grading system that incorporates eating quality parameters and technological advancements.

Background Hansen's disease is a chronic, infectious and transmissible disease that is considered a public health problem in Brazil. Hansen's disease is marked by stigma and prejudice, because it carries with it a strong negative social image, reinforced by policies of social isolation in the community. Methods A qualitative study was conducted in Ribeirão Preto, an inland city of the state of São Paulo, Brazil. Eleven patients under treatment for the disease were interviewed. The interviews were audio recorded and transcribed in full, then were analyzed through the stages of transcription, transposition and reconstitution, as informed by concepts proposed by Goffman. Results The results showed that the marks of stigma are still present in the twenty-first century and were presented in two axes: 'Stigma and work for the person affected by Hansen's disease' and 'The experience of stigma in the family'. The participants refer to fears of losing their jobs and of being ridiculed, which stops them talking about the disease. Regarding their families, the participants reported episodes of discrimination, the creation of family secrets and fear of relatives' reactions. Conclusions All these aspects interfere in the follow-up and treatment of patients and need to be considered and welcomed by health professionals. It is recommended that these aspects are addressed in the initial training and continuing education of health professionals. Contexte La maladie de Hansen est une maladie chronique, infectieuse et transmissible, considérée comme un problème de santé publique au Brésil. La maladie de Hansen est marquée par la stigmatisation et les préjugés, car elle véhicule une image sociale fortement négative, renforcée par des politiques d'isolement social au sein de la communauté. Méthodes Étude qualitative menée à Ribeirão Preto, une ville intérieure de l'État de São Paulo, au Brésil. Onze patients traités pour la maladie ont été interrogés. Les entretiens ont été enregistrés et transcrits intégralement, et ont été analysés en suivant les étapes de transcription, de transposition et de reconstitution, selon les concepts proposés par Goffman. Résultats Les résultats montrent que les marques de la stigmatisation sont toujours présentes au 21ème siècle et ont été présentées selon deux axes : 'La stigmatisation et le travail pour la personne affectée par la maladie de Hansen' et 'L'expérience de la stigmatisation dans la famille'. Les participants évoquent la peur de perdre leur emploi, la peur d'être ridiculisés, ce qui les pousse à ne pas parler de la maladie. En ce qui concerne les familles, les participants ont rapporté des épisodes de discrimination, la création de secrets de famille et la peur des réactions des proches. Conclusions Tous ces aspects interfèrent dans le suivi et le traitement des patients et doivent être pris en compte et accueillis par les professionnels de la santé. Il est recommandé que ces aspects soient abordés dans la formation initiale et la formation continue des professionnels de la santé.

The stink bug Glyphepomis spinosa Campos & Grazia (Hemiptera: Pentatomidae) is a potential rice pest in Brazil. This study evaluates the interaction between silicon sources and 3 rice cultivars (BRS Esmeralda, Canela de Ferro, and IRGA 417) and examines how increasing silicon levels affect the stylet probing behavior of G. spinosa. The experiment was set up in a completely randomized design with a 3 × 3 factorial scheme (silicon sources: calcium silicate, potassium silicate, a control, and 3 rice cultivars). Fertilizing rice plants with Si altered the probing behavior of the stink bug G. spinosa. The cultivar interaction by Si source was significant in a few variables. This was evidenced by longer periods without ingestion, prolonged time to the first stylet probe (initial probing), and less time spent in cellular maceration. This result supports the use of electropenetrography as a tool to evaluate resistance inducers in plants. [ABSTRACT FROM AUTHOR]

The objective of this study is to analyze the accuracy and applicability of the AncesTrees software with respect to a set of cranial measurements of a Brazilian sample consisting of 114 identified skulls from two osteological collections, predominantly composed of European (n  = 59), African (n  = 35), and admixed individuals (n  = 20). Twenty-four different craniometric measurements are performed and input to AncesTrees via two algorithms, one of which is used in three configurations, with different ancestral groups integrated in the model. The software exhibits superior performance in the estimation of European individuals, reaching 73% accuracy, compared with 66% in the African individuals. Those individuals classified as admixed produce a variety of ancestral classifications, mainly European. Overall, the most accurate combination of AncesTrees is obtained using ancestralForest with only the European and African groups integrated into the algorithm, where the accuracy reaches 70%. The applicability of this software to a specific population is fragile because of the high admixing load, making it necessary to create a more representative anthropometric database of the Brazilian people. Key points Ancestry estimation methods are seldom validated in Brazil. AncesTrees performed poorly on our sample, with a maximum accuracy of 70%. Brazil's highly mixed population hinders ancestry estimation. Mixed individuals (pardos) are predominantly classified as Europeans. The insertion of Brazilian metric data into the AncesTrees database would produce better results. [ABSTRACT FROM AUTHOR]

We study whether college admissions should implement quotas for lower-income applicants. We develop an overlapping-generation model and calibrate it to data from Brazil, where such a policy is widely implemented. In our model, parents choose how much to invest in their child's education, thereby increasing both human capital and likelihood of college admission. We find that, in the long run, the optimal income-based affirmative action increases welfare and aggregate output. It improves the pool of admitted students, but distorts pre-college educational investments. The welfare-maximising policy benefits lower- to middle-income applicants with income-based quotas, while higher-income applicants face fiercer competition in college admissions. The optimal policy reduces intergenerational persistence of earnings by 5.7% and makes nearly 80% of households better off. [ABSTRACT FROM AUTHOR]

Amazonian savannas are isolated patches of open habitats found within the extensive matrix of Amazonian tropical forests. There remains limited evidence on how Amazonian plants from savannas differ in the traits related to drought resistance and water loss control. Previous studies have reported several xeromorphic characteristics of Amazonian savanna plants at the leaf and branch levels that are linked to soil, solar radiation, rainfall and seasonality. How anatomical features relate to plant hydraulic functioning in this ecosystem is less known and instrumental if we want to accurately model transitions in trait states between alternative vegetation in Amazonia. In this context, we combined studies of anatomical and hydraulic traits to understand the structure–function relationships of leaf and wood xylem in plants of Amazonian savannas. We measured 22 leaf, wood and hydraulic traits, including embolism resistance (as P50), Hydraulic Safety Margin (HSM) and isotope-based water use efficiency (WUE), for the seven woody species that account for 75% of the biomass of a typical Amazonian savanna on rocky outcrops in the state of Mato Grosso, Brazil. Few anatomical traits are related to hydraulic traits. Our findings showed wide variation exists among the seven species studied here in resistance to embolism, water use efficiency and structural anatomy, suggesting no unique dominant functional plant strategy to occupy an Amazonian savanna. We found wide variation in resistance to embolism (−1.6 ± 0.1 MPa and −5.0 ± 0.5 MPa) with species that are less efficient in water use (e.g. Kielmeyera rubriflora , Macairea radula , Simarouba versicolor , Parkia cachimboensis and Maprounea guianensis) showing higher stomatal conductance potential, supporting xylem functioning with leaf succulence and/or safer wood anatomical structures and that species that are more efficient in water use (e.g. Norantea guianensis and Alchornea discolor) can exhibit riskier hydraulic strategies. Our results provide a deeper understanding of how branch and leaf structural traits combine to allow for different hydraulic strategies among coexisting plants. In Amazonian savannas, this may mean investing in buffering water loss (e.g. succulence) at leaf level or safer structures (e.g. thicker pit membranes) and architectures (e.g. vessel grouping) in their branch xylem.

The Covid-19 caused by the SARS-CoV-2 virus has shown how inadequate institutional strategies interact with, and exacerbate, social inequalities, thus impacting upon the intensity of the harm produced and amplifying negative consequences. One of the lessons from this pandemic, which happens against the background of other, interconnected systemic crises, is the urgency of adopting a 'whole-of-society' approach to determining what does and what does not work in the context of a health emergency response. However, how can institutional performance in health emergency response be assessed? How to make sense of success or failure? We argue that the adoption of a risk governance approach sheds light on institutional performance in the response to health emergencies. Risk governance is particularly pertinent in situations where the potential for extreme consequences is considered high, where there are enormous uncertainties regarding the consequences and where different values are present and in dispute. Based on a documentary evidence review, we analyse the Brazilian response to Covid-19 by considering: (1) how the Brazilian federal government performed on its central role of managing the national response, (2) the reactions from other actors prompted by this performance and (3) the main observed effects emerging from this scenario. We argue that the Brazilian federal government response was weak in five risk governance parameters that are essential in a health crisis response: risk communication, transparency and accessibility of data, negotiation between actors, social cohesion and public participation and decisions based on technical and scientific evidence, resources and contexts. The neglect of risk governance parameters, combined with an attempt to spread doubt, confusion and disinformation—which could be termed a 'governance by chaos'—is an important element for making sense of the effects and controversies surrounding Covid-19 in Brazil.

Phosphorus (P) availability to forest trees is often limited by local soil conditions that increase its fixation to soil minerals. In certain regions, atmospheric-P inputs can compensate for low soil-P availability. Among atmospheric-P sources, desert dust is the most dominant. However, the effects of desert dust on P nutrition and its uptake mechanisms by forest trees are currently unknown. We hypothesized that forest trees that naturally grow on P-poor soils or soils with high soil-P fixation capacity can acquire P from desert dust deposited on their leaves via direct foliar uptake, bypassing the soil, thus promoting tree growth and productivity. We performed a controlled greenhouse experiment with three forest tree species: Palestine Oak (Quercus calliprinos) and Carob (Ceratonia siliqua), native to the NE edge of the Saharan desert, and Brazilian peppertree (Schinus terebinthifolius), native to the Atlantic Forest in Brazil, which is located on the western part of the trans-Atlantic Saharan dust route. To simulate natural dust deposition events, the trees had desert dust applied directly upon their foliage and were monitored for growth and final biomass, P levels, leaf surface pH and the rate of photosynthesis. The dust treatment increased the P concentration significantly by 33–37% in Ceratonia and Schinus trees. On the other hand, trees that received the dust displayed a 17–58% reduction in biomass, probably related to particle coverage of the leaf surface that inhibited photosynthesis by 17–30%. Overall, our findings show that direct P uptake from desert dust can be an alternative P uptake pathway for multiple tree species under P-deficient conditions, with implications for forest trees' P economy.

Green lacewings (Neuroptera: Chrysopidae) are predators commonly found in coffee plantations in Brazil that can serve as important biological control agents against insect pests such as the coffee leaf miner, Leucoptera coffeella (Lepidoptera: Lyonetiidae). However, the efficacy of different lacewing species in controlling L. coffeella needs to be evaluated before they are used in augmentative biological control programs. Here, laboratory experiments were conducted to investigate the effects of the L. coffeella developmental stage on the functional response of 3 species of green lacewings: Chrysoperla externa , Ceraeochrysa cincta , and Ceraeochrysa cornuta. The attack rate, handling time, and the number of prey attacked during 24 h with different densities (1, 2, 4, 8, 16, 32, and 64 individuals) of either L. coffeella larvae or pupae were recorded for each of the 3 lacewing species. Based on logistic regression models, all 3 predators showed a Type II functional response when consuming both larvae and pupae of L. coffeella. All 3 species also had similar attack rates (0.0091 larva/h and 0.0095 pupa/h), handling times (3.5 and 3.7 h for larvae and pupae, respectively), and estimated number of prey attacked during the observation period (6.9 larvae and 6.6 pupae) for L. coffeella larvae and pupae. Therefore, our laboratory studies show that the 3 green lacewings Ch. externa , Ce. cincta , and Ce. cornuta have potential for the biological control of L. coffeella , although these results need to be confirmed under field conditions. These findings have implications for the selection of lacewings for augmentative L. coffeella biocontrol. [ABSTRACT FROM AUTHOR]

Mountains play a crucial role in the origin and maintenance of Neotropical biodiversity, but there are still unanswered questions about the diversification of the campos rupestres (CR), an herbaceous-shrubby sky-island vegetation in eastern South America. For orchids distributed across this disjunct rock habitat, difficulties with distinguishing morphological taxa add an additional challenge to disentangling the history of divergence. Here, we combined the power of ddRAD genomic data with broad sampling of Bulbophyllum sect. Didactyle (Orchidaceae), across the CR and other Neotropical outcrops, to estimate evolutionary relationships and evaluate the biogeography of the group's diversification. Although genetic lineages generally align with geographic disjunctions, we also observe distantly related lineages within some previously recognized species. For such taxa, their lack of monophyly and a shared regional divergence pattern suggests a complex history that may include unrecognized diversity. When viewed through the lens of morphological variability, our study raises intriguing questions about the persistence and permeability of species barriers among orchid populations. These results, in addition to the recency of the divergence history of B. sect. Didactyle, provide insights about hypothesized community level vs. species-specific paths of diversification across the Neotropical sky-islands of the CR. [ABSTRACT FROM AUTHOR]

Background and Aims We examined the relationship between reproductive allocation and vegetative growth in three monoicous sexual systems of bryophytes. The sexual systems show a gradient of increasing distance between the sexes, from gonioautoicous to cladautoicous to rhizautoicous. Here, we investigated the following two hypotheses: (1) reproductive allocation differs between sexes and sexual systems, and male reproductive allocation increases with increasing distance between male and female gametangia; and (2) reproductive allocation is negatively related to vegetative growth. Methods We sampled the three sexual systems, represented by three moss species of the genus Fissidens in the Atlantic Forest of Southeastern Brazil. Ramets were washed in the laboratory; the reproductive structures were detached from the vegetative ramets and sorted regarding sex and individual, dried at 70 °C for 72 h, and weighed in an ultramicrobalance. We calculated the mean reproductive and vegetative mass and reproductive allocation and used generalized linear models to test our predictions. Key Results Reproductive allocation differed between species and sexes. It was higher in the rhizautoicous than in the cladautoicous and gonioautoicous species. Mean reproductive allocation was greater in males than in females of the rhizautoicous species, greater in females than males of the cladautoicous species, and did not differ between the sexes in the gonioautoicous species. Estimates of reproductive and vegetative mass were positively related in females of the rhizautoicous species. Vegetative mass was not related to reproductive allocation in the gonioautoicous species, but negatively related to reproductive allocation in the male and female branchlets of the cladautoicous species and in the female ramets of the rhizautoicous species. Conclusions The reproductive allocation patterns differ between the rhizautoicous species and the 'truly' monoicous species, with shorter intersexual distances, which implies that our hypotheses were supported only in part. We suggest that the hypotheses should be reformulated and tested further by comparing 'truly' monoicous species with dioicous species and by including other genera. [ABSTRACT FROM AUTHOR]

Introduction Adverse drug reactions (ADRs) to anti-infectives affect especially hospitalized children and contribute to increased morbidity, mortality, length of stay, and costs in healthcare systems. Objective To assess ADRs associated with anti-infective use in Brazilian hospitalized children. Methods A prospective cohort study was conducted in 5 public hospitals over 6 months. Children aged 0–11 years and 11 months who were hospitalized for more than 48 h and prescribed anti-infectives for over 24 h were included. Results A total of 1020 patients met the inclusion criteria. Of these, 152 patients experienced 183 suspected ADRs. Most reactions were related to the gastrointestinal system (65.6%), followed by skin reactions (18.6%). Most reactions were classified as probable causality (58.5%), moderate severity (61.1%), and unavoidable (56.2%). Our findings showed that ADRs were associated with increased length of stay (P <.001), increased length of therapy (P <.015), increased days of therapy (P =.038), and increased number of anti-infectives prescribed per patient (P <.001). Conclusion Almost 15% of hospitalized children exposed to anti-infectives presented suspected ADRs. Their occurrence was classified as probable, of moderate severity, and unavoidable. ADRs were significantly influenced by the length of hospital stay and the number of anti-infectives prescribed per patient. [ABSTRACT FROM AUTHOR]

Background and Aims Trap flowers are fascinating cases of adaptation, often linked to oviposition-site mimicry systems. Some trap flowers do not imprison pollinators for a pre-determined period, but rather force them to move through a specific path, manipulating their movements in a way that culminates in pollen transfer, often as they leave through a secondary opening. Methods We investigated the previously unknown pollination system of the lady's slipper orchid Phragmipedium vittatum and assessed the function of micro-morphological traits of its trap flowers. Key Results Our observations revealed that P. vittatum is pollinated by females of two hoverfly species (Syrphidae). Eggs laid by flies on or near raised black spots on the flowers indicate that the orchid mimics aphids which serve as food for their aphidophagous larvae. Dark, elevated aphid-like spots appear to attract the attention of hoverflies to a slipping zone. This region has downward projecting papillate cells and mucilage secretion that promote slipperiness, causing potential pollinators to fall into the labellum. They then follow a specific upward route towards inner aphid-like spots by holding onto upward oriented hairs that aid their grip. As hoverflies are funnelled by the lateral constriction of the labellum, they pass the stigma, depositing pollen they may be carrying. Later, they squeeze under one of the articulated anthers which places pollen smears onto their upper thorax. Then, they depart through one of the narrow lateral holes by holding onto hairs projecting from the petals. Conclusions This study confirms the system of aphid mimicry in Phragmipedium and highlights the sophisticated micro-morphological traits used by trap flowers in pollinator attraction, trapping, guidance and release, thus promoting precise pollen transfer.

During the 2000s, Brazil accumulated a substantial amount of foreign reserves through foreign exchange market interventions undertaken by its Central Bank. Mainstream economics considers such interventions a restriction to monetary policy autonomy. This article analyses the relationship between monetary policy autonomy and exchange rate regimes theoretically and empirically for the Brazilian economy. We argue that the compensation principle, as a direct derivation of the endogenous money approach, is an alternative to both the trilemma and dilemma views in the mainstream perspective. Then, we provide empirical evidence in favour of the compensation principle in the Brazilian economy by verifying the exogeneity of the interest rate and estimating a vector error-correction model (VECM) that indicates that the foreign reserves do not have a long-term effect on the monetary base, while they present a significant and large effect on the repos account. In line with the compensation view, we conclude that in the 2000s, Brazil had more monetary policy autonomy than conventional approaches would have suggested. [ABSTRACT FROM AUTHOR]

Indonesian clove cigarettes—called "kretek" due to the crackling sound that can be heard when the product burns—are tobacco products containing clove and the "saus", a mixture of essential oils and plant extracts whose ingredients are mostly kept in secret. It is important to determine which ingredients those are to properly assess the effects that clove cigarettes can cause. An organoleptic, qualitative and quantitative analysis was made in 9 different brands of clove cigarettes obtained in Brazil. Nicotine, eugenol, menthol, and β-caryophyllene were quantified through gas chromatography coupled to mass spectrometry. The samples presented 20 different compounds, and all samples had a different combination of the compounds. Nicotine concentrations were generally higher than eugenol, and lower than nicotine concentration in a conventional cigarette. One sample had menthol even though the cigarette pack did not inform that it was a menthol product. There were traces of 2 unusual substances. Clindamycin is an antibiotic that can be used to treat bacterial infections in respiratory airways, and octodrine is an amphetaminic stimulant used in nutritional supplements, considered as a substance of doping by the World Anti-Doping Association. The presence of both substances was not tested using certified reference materials, but its possible presence raises concern about the compounds in kretek cigarettes. There should be more studies about the contents of clove cigarettes, to improve antitobacco legislations and regulations. This way it would be possible to properly inform the risks of smoking clove cigarettes and to diminish the number of tobacco users throughout the world. [ABSTRACT FROM AUTHOR]

Objective COVID-19 in post-partum women is commonly overlooked. The present study assessed whether puerperium is an independent risk factor of COVID-19 related in-hospital maternal death and whether fatality is preventable in the Brazilian context. Methods We retrospectively studied the clinical data of post-partum/pregnant patients hospitalized with COVID-19 gathered from a national database that registered severe acute respiratory syndromes (SIVEP-Gripe) in Brazil. Logistic regressions were used to examine the associations of in-hospital mortality with obstetric status and with the type of public healthcare provider, adjusting for socio-demographic, epidemiologic, clinical and healthcare-related measures. Results As of 30 November 2021, 1943 (21%) post-partum and 7446 (79%) pregnant patients of age between 15 and 45 years with COVID-19 that had reached the clinical endpoint (death or discharge) were eligible for inclusion. Case-fatality rates for the two groups were 19.8% and 9.2%, respectively. After the adjustment for covariates, post-partum patients had almost twice the odds of in-hospital mortality compared with pregnant patients. Patients admitted to private (not-for-profit) hospitals, those that had an obstetric centre or those located in metropolitan areas were less likely to succumb to SARS-CoV-2 infection. Those admitted to the Emergency Care Unit had similar mortality risk to those admitted to other public healthcare providers. Conclusion We demonstrated that puerperium was associated with an increased odds of COVID-19-related in-hospital mortality. Only part of the risk can be reduced by quality healthcare such as non-profit private hospitals, those that have an obstetric centre or those located in urban areas. [ABSTRACT FROM AUTHOR]

Forensic anthropologists perform specialised analysis, mainly involving skeletonised human remains, cadavers in advanced stages of decomposition, disassociated elements from the human body, and human remains in extreme carbonisation. The main objectives of the forensic anthropology expertise are human identification and assisting in determining the cause and manner of death. Estimating the time since death is also a priority for some cases, especially ones involving missing persons. This science works on individual cases, violent deaths, missing persons, mass disasters, suspected violations of human rights, and crimes against humanity. Forensic anthropological evidence is, in general, very sensitive. Thus, it is important to detail aspects relevant to the maintenance of the chain of custody at all phases of the investigation, as well as standardise the actions of the individuals involved. This aims to preserve the evidence integrity and sameness (Sameness: free translation of the Portuguese word "mesmidade", derived from a Spanish word that does not possess a translation to Portuguese. Sameness of evidence is understood as the guarantee that the evidence under valuation (or under analysis of its probative value) is exactly and integrally the same one which was collected, corresponding, therefore, to "the same" (and not "part of", "derived from"), safeguarding its value. Brazil Law No. 13.964 of 14 December 2019 establishes and lists 10 phases related to the evidence chain of custody that must be followed. These newly introduced requirements resulted in the need for adaptation of the forensic, investigative, and legal actors involved in an investigation, and in the detailed description of the procedures for the different areas related to criminalistics, including forensic anthropology. The information provided in this article should be interpreted as recommendations, even though their non-compliance may weaken the investigative and forensic analysis processes in whole or in part.

Health-care workers (HCWs) on the frontlines of the 2019 Coronavirus Disease 2019 (COVID-19) have a high risk of acquiring and dying from the disease. Brazil is a country with high morbimortality and ranks highest in general mortality from COVID-19. A large proportion of medical doctors (MDs) is dying, impacting in the workforce. As part of the research by Fiocruz on working conditions among HCWs, we have conducted this study of death among MDs. We analyzed data from Federal Council of Medicine, the only national platform with details about deaths in MDs. A broad search of other sources, including the Ministry of Health, was done, but unfortunately, the data does not exist. A total of 622 MDs died from March 2020 to March 2021: 87.6% male and 75% over age 60. The Southeast had the highest percentage (34.7%), followed by the Northeast (27.2%), and rankings by state showed Rio de Janeiro (15.8%), followed by São Paulo, Pará, Paraná and Paraíba, totalizing 50.1%. The specialties with highest mortality were gynecology (12.2%), pediatrics (10.0%), internal medicine (9.3%), general surgery (7.8%) and cardiology (7.6%). May 2020 was the month of worst mortality (16.9%) followed by July and June. A slow decline was observed until October, when Brazil begun to experience the ‘‘second wave’’. The vaccination of MDs began at the end of January 2021 and has not been sufficient time to evaluate the impact on morbimortality. The results of a study of 50 professional categories are under analysis and will be published soon as well as a study of ‘‘invisible’’ HCWs, who do not have specific training but are essential to supporting health care system, from primary care units to high-complexity hospitals. We hope that the results of these studies will improve links among managers, those who define public policies, and union leaders, achieving better workplace and living conditions, minimizing health and socioeconomic disparities. Key messages: This study is about death by COVID-19 among medical doctors in Brazil, as part of a large one on professional categories, essentials to supporting health care system, conducted by FIOCRUZ. This stdy is part of a large one on professional categories, essentials to supporting health care system, conducted by FIOCRUZ. [ABSTRACT FROM AUTHOR]

Medicinal plants have been employed as an alternative method to treat diabetes. One is Cissus sicyoides , a plant from the Amazon region (Northern Brazil), which is morphologically similar to Wedelia paludosa , a plant easily found in Southern Brazil. Thus, this study aimed to assess the potential toxicity of C. sicyoides and W. paludosa 's leaves water extracts. Through phytochemical screening, phenolic compounds and alkaloids were observed in both species and coumarins only W. paludosa 's aqueous extract. Phenolic compounds were quantified in both extracts and C. sicyoides presented 1.36 ± 0.04 mg/pyrogalic acid equivalent (PAE), whereas W. paludosa presented 3.27 ± 0.07 mg/PAE. Total antioxidant power was measured by the ferric reduction assay. Cissus sicyoides exhibited total antioxidant activity of 748.0 ± 104.5 μM and W. paludosa , 1971.5 ± 141.0 μM. Cissus sicyoides showed an inhibition rate for the alpha-glucosidases enzyme assay of 55.2 ± 1.7% and W. paludosa , 85.8 ± 9.7%. The formation of reactive oxygen species was evaluated by the DCFH-DA method, its formation being higher in W. paludosa 's water extracts than in C. sicyoides. Cell viability was evaluated by the Sulforhodamine B and MTT assays. Wedelia paludosa 's extracts' exposure presented a cell viability close to positive control starting from 2 mg/mL to 30 mg/mL, whereas C. sicyoides demonstrated statistical significant low viability at the highest concentration when compared with the negative control. Moreover, cell death mechanism was investigated, having W. paludosa 's extract indicated death by necrosis. The results suggest low toxicity for C. sicyoides ' extract and high toxicity for W. paludosa 's extract. [ABSTRACT FROM AUTHOR]

Inversion of large-scale gravity data set is generally a challenging problem due to memory requirements and computational costs. In this study, based on VNet, we present an efficient strategy for the large-scale gravity inverse problem by simultaneously tackling several base-scale gravity data. We first construct a large number of base-scale geological models including gravity sources, with different shapes and dimensions, and also their forward model data sets. Then, the idea of semantic segmentation is used to train an inversion network. In the next step, a finite number of base-scale and similar size area of gravity data, clipped from the original large data set with a fixed stride, are fed into the trained network. Finally, the individual recovered models are combined to provide the inversion result for the whole subsurface area. The feasibility and effectiveness of the presented inversion algorithm are tested on a large-scale complicated synthetic model. The algorithm is, then, verified for the inversion of the gravity data set obtained over the Morro do Engenho complex in central Brazil. [ABSTRACT FROM AUTHOR]

Dengue is a serious public health concern in Brazil and globally. In the absence of a universal vaccine or specific treatments, prevention relies on vector control and disease surveillance. Accurate and early forecasts can help reduce the spread of the disease. In this study, we developed a model for predicting monthly dengue cases in Brazilian cities 1 month ahead, using data from 2007–2019. We compared different machine learning algorithms and feature selection methods using epidemiologic and meteorological variables. We found that different models worked best in different cities, and a random forests model trained on monthly dengue cases performed best overall. It produced lower errors than a seasonal naive baseline model, gradient boosting regression, a feed-forward neural network, or support vector regression. For each city, we computed the mean absolute error between predictions and true monthly numbers of dengue cases on the test data set. The median error across all cities was 12.2 cases. This error was reduced to 11.9 when selecting the optimal combination of algorithm and input features for each city individually. Machine learning and especially decision tree ensemble models may contribute to dengue surveillance in Brazil, as they produce low out-of-sample prediction errors for a geographically diverse set of cities.

Background Although there are previous systematic reviews about the oral health-related quality of life (OHRQoL) impact among children and adolescents after orthodontics treatment, there is no definition for the magnitude of these impacts during the therapy. Objective To systematically analyse the literature on changes in the quality of life of children and adolescents during orthodontic treatment. Limitations Almost all the studies included in this review are non-randomized clinical trials, which are susceptible to several biases that affect the certainty of evidence obtained, especially by confounding factors and the lack of a control group. Conclusions and implications Based on very low certainty of evidence, wearing appliances does not seem to have a significant negative impact during the first year of orthodontic treatment. However, the meta-analytic results suggest that functional limitations in the first 3 months of treatment can be slightly more critical for the impact on the oral health quality of life and consequent patient adherence to treatment. Funding This study was financed by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brazil (CAPES), Conselho Nacional de Desenvolvimento Científico e Tecnológico - Brazil (CNPq), and Fundação de Amparo à Pesquisa do Estado de Minas Gerais – Brazil (FAPEMIG).

Ambient seismic noise is now routinely used to study the Earth's interior. For an isotropic homogeneous medium, the basic assumption to extract seismic phases from a station pair is that the sources of seismic noise are distributed in such a way that there is a uniform energy flux around the station pair. In general, however, some particular azimuthal directions may dominate the energy flux, which directly affects the extracted interstation empirical Green's function (EGF). To solve this problem, we analysed synthetic cross-correlation functions (CCFs) from seismic pulses propagated in isotropic and anisotropic heterogeneous half-space media towards a station pair under the assumptions of uniformly and non-uniformly distributed sources of noise. A reliable EGF signal can be extracted by applying three processing steps: (1) normalizing the number of repeated stationary sources, (2) normalizing the energy of each excited source and (3) selecting coherent CCFs in the final stacking. In this way, three different classes of station pairs were identified based on the number of CCFs used in the stacking procedure. We introduced and applied a new method based on weighted root-mean-square stacking (WRMS) to the CCFs of more than 33 months of ambient noise recorded from January 2016 to September 2018 at 75 broad-band stations in West-Central Brazil. In the case of non-uniform distribution of source of noise, simple classical linear stacking of CCFs produces distorted EGFs. However, the waveform extracted by the WRMS method is very similar to the Rayleigh waves excited by an earthquake (on 2017 January 3) near one receiver observed at the other receiver. Moreover, synthetic tests and a comparison between extracted and earthquake signals show that although the WRMS method can extract the main part of the signal that is propagated on the shortest path, it cannot recover the energy parts propagated on multipath. Despite the N–W directionality in the geometry of the array, the rose-diagram results indicate no significant spatial variations in the energy level of EGFs extracted by the WRMS stacking, whereas the EGFs extracted by the classical linear stacking indicate the extreme directionality of energy flow in different period ranges. Rayleigh wave group and phase velocity tomographic maps resolved by the EGFs derived from the WRMS method indicate a clear boundary along the Asuncion and Rio Grande Arches between the Chaco-Paraná and the Paraná basins at the shorter period, while the tomographic maps in the same periods which were calculated by other stacking methods cannot clearly separate basins and arcs. Our tomographic maps at longer periods indicate variations of Moho depth and lithospheric velocities. [ABSTRACT FROM AUTHOR]

Located on the western continental tip of the Fernando de Noronha transform fracture (FNTF), northeastern Brazil, the Eocene–Oligocene Mecejana Phonolitic Province (MPP) was subjected to a multi-methodological study, comprising field and microscopic characterization, mineral and whole-rock chemistry, and Sr-Nd isotopes. These rocks intrude the Precambrian crystalline basement, forming mainly plugs oriented in the NE–SW direction. They are composed of alkali basalt, phono-tephrite, tephri-phonolite, and phonolite with phenocrysts of nepheline and sanidine, and minor diopside, aegirine-augite, aegirine, kaersutite, biotite and titanite. Chemically, they are sodic (Na2O/K2O > 1) and display Light Rare Earth Elements (LREE) enrichment, concave upward or flat Heavy Rare Earth Elements (HREE) patterns, weak to strong Eu anomaly, and high contents of Nb, Ta and Zr. They delineate two chemical groups, the less-evolved one comprising basalt to tephri-phonolites and the more evolved constituted by phonolites. Oxide and trace element modeling points out to an evolution by fractional crystallization, leaving olivine-rich gabbro and foidolite/nepheline syenite cumulates, respectively. The analyzed samples have Sr-Nd isotopic ratios akin to ocean island basalt (OIB) rocks (positive εNd of +3.0 to +0.9 at 30 Ma) and low to high 87Sr/86Sri (at 30 Ma) of 0.70264–0.70955. The data suggest a three-stage evolution model for the MPP: (1) <5% partial melting of a metasomatized phlogopite-amphibole-garnet peridotite generates an alkali basalt melt, (2) polybaric differentiation of this melt at crustal level (~570–220 MPa, 1040–645°C) leads firstly to phono-tephrites and tephri-phonolites and then to (3) foidolite and nepheline syenite. Petrographic, chemical, and isotopic characteristics of the MPP and similar rocks of the Fernando de Noronha islands suggest the control by the FNTF and reactivation of NE–SW trending deep-rooted Precambrian faults allowing channeling and emplacement of the alkaline magmas.

Hematological parameters can provide key information to an animal health status. However, this information is usually hard to obtain. Here, we described the hematological parameters of Leptodactylus podicipinus in the Brazilian Pantanal. We measured red blood cell morphometrics, erythrogram, and leukogram. We also tested for phylogenetic signal in the erythrogram and leukogram of 48 frog species from 15 families, testing if body size explains their variation. Lymphocytes were the most abundant leukocytes (>60%) in L. podicipinus , followed by neutrophils (∼10%). Given that L. podicipinus is an abundant and widely distributed species in central Brazil, knowing its hematological pattern can help establish a baseline and improve its use as a bioindicator of environmental degradation. Mean corpuscular hemoglobin and value contributed more to the phylomorphospace of erythrogram, in which Leptodactylus spp. and Hypsiboas raniceps had lower values of these variables, whereas Bufotes viridis and Hyla arborea had high values. The phylogenetic signal was spread throughout the dimensions of the leukogram phylomorphospace. The variables that most contributed to it were total leukocytes counts, lymphocytes, and neutrophils. We also found a moderate phylogenetic signal for both the erythrogram and leukogram. Accordingly, body size accounted for a low proportion of variation in both the leukogram (4.7%) and erythrogram (0.57%). By applying phylogenetic comparative methods to hematological parameters, our results add a new perspective on the evolution of blood cell physiology in frogs. [ABSTRACT FROM AUTHOR]

Racial health inequities may be partially explained by area-level factors such as residential segregation. In this cross-sectional study, using a large, multiracial, representative sample of Brazilian adults (n  = 37,009 individuals in the 27 state capitals; National Health Survey (Pesquisa Nacional de Saúde), 2013), we investigated 1) whether individual-level self-rated health (SRH) (fair or poor vs. good or better) varies by race (self-declared White, Brown, or Black) and 2) whether city-level economic or racial residential segregation (using dissimilarity index values in tertiles: low, medium, and high) interacts with race, increasing racial inequities in SRH. Prevalence of fair or poor SRH was 31.5% (Black, Brown, and White people: 36.4%, 34.0%, and 27.3%, respectively). Marginal standardization based on multilevel logistic regression models, adjusted for age, gender, and education, showed that Black and Brown people had, respectively, 20% and 10% higher prevalence of fair or poor SRH than did White people. Furthermore, residential segregation interacted with race such that the more segregated a city, the greater the racial gap among Black, Brown, and White people in fair or poor SRH for both income and race segregation. Policies to reduce racial inequities may need to address residential segregation and its consequences for health. [ABSTRACT FROM AUTHOR]

Depending on the magnitude and nature of a disaster, identifying the victims can be a complex task that requires coordinated work by disaster victim identification (DVI) teams based on pre-established protocols. Thus, the analysis of fingerprints has been presented as a method to establish, when possible, the identity of the victims during the DVI process. This study discusses the importance of this primary method of identification and the results obtained in four different disasters in which Brazilian DVI teams were involved: the Air France Flight AF447 plane crash in the Atlantic Ocean, floods and mudslides in the State of Rio de Janeiro, Brazil, the LaMia Flight 2933 plane crash in Colombia, and the tailings dam collapse in Brumadinho, Brazil. Here, we also report the use of the automatic fingerprint capture and identification system, called Alethia, developed by the Federal Police of Brazil and used in the victim identification process in the two latter events mentioned above. This article presents four different disasters that occurred in Brazil and overseas and involved Brazilian DVI teams in the identification process, focusing on fingerprint identification (Air France Flight AF447, floods and mudslides in the State of Rio de Janeiro, Brazil, LaMia Flight 2933, and the Brumadinho tailings dam collapse). This article also describes the evolution of the DVI process in Brazil, including a description of the technology currently used by Brazilian fingerprint experts (Alethia). This article reports how the Alethia System was used in the disasters and how it optimized the human identification process when compared to traditional methods. [ABSTRACT FROM AUTHOR]

Background: This study examined the variation in city-level amenable mortality, i.e. mortality due to conditions that can be mitigated in the presence of timely and effective healthcare, in 363 Latin American cities and measured associations between amenable-mortality rates and urban metrics.Methods: We used death records from 363 cities with populations of >100 000 people in nine Latin American countries from 2010 to 2016. We calculated sex-specific age-adjusted amenable-mortality rates per 100 000. We fitted multilevel linear models with cities nested within countries and estimated associations between amenable mortality and urban metrics, including population size and growth, fragmentation of urban development and socio-economic status.Results: Cities in Mexico, Colombia and Brazil had the highest rates of amenable mortality. Overall, >70% of the variability in amenable mortality was due to between-country heterogeneity. But for preventable amenable mortality, those for which the healthcare system can prevent new cases, most of the variability in rates occurred between cities within countries. Population size and fragmentation of urban development were associated with amenable mortality. Higher fragmentation of urban development was associated with lower amenable mortality in small cities and higher amenable mortality in large cities. Population growth and higher city-level socio-economic status were associated with lower amenable mortality.Conclusions: Most of the variability in amenable mortality in Latin American cities was due to between-county heterogeneity. However, urban metrics such as population size and growth, fragmentation of urban development and city-level socio-economic status may have a role in the distribution of amenable mortality across cities within countries.

How does enforcement of labour regulations shape the labour market effects of trade? We combine local economic shocks generated by the unilateral trade liberalisation in Brazil and enforcement variation across regions to show that regions with stricter enforcement observed: (i) lower informality; (ii) larger losses in overall employment; (iii) greater reductions in the number of formal plants. Regions with weaker enforcement experienced opposite effects. All these effects are concentrated on low-skill workers. Our results indicate that greater flexibility introduced by informality allows both formal firms and low-skill workers to cope better with adverse labour market shocks. [ABSTRACT FROM AUTHOR]

Background To design better measures to contain the Covid-19 epidemics, it is relevant to know whether socioeconomic factors are associated with a higher risk of death by Covid-19. This work estimates the effects of individual socioeconomic characteristics on the risk of death by Covid-19. Methods Logistic models were estimated to assess the effect of socioeconomic characteristics (income, race/ethnicity, schooling, occupation and economic activity) on the risk of death from Covid-19. For this purpose, Covid-19 individual death records in Rio de Janeiro state, Brazil were combined with the Annual Register of Social Information, which contains socioeconomic information about formal workers. Findings Workers employed in establishments in the health and public safety sectors present a risk of dying 2.46 and 2.25 times higher than those employed in other activities. Non-white people, men, and those who work in the Metropolitan Region are also more likely to die from Covid-19. People with higher education are 44% less likely to die from the disease. Conclusions Some population groups are more vulnerable to the Covid-19 pandemic and individual socioeconomic conditions play a relevant role in the probability of death by the disease. That should be considered in the design of prevention policies to be adopted. [ABSTRACT FROM AUTHOR]

Fishing systems provide employment, income generation, poverty alleviation, and food security. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Management actions have ecological and social implications that must be addressed carefully. We applied a bioeconomic game-theoretical model to the four-gear mullet fishery in southern Brazil—one industrial LSF (purse seine) and three artisanal SSFs (gillnet, beach seine, and drift net). All fishing gears target adult individuals during mullet's reproductive migration. First, we explored whether the current fishing efforts of all fishing gears could persist over time. Second, we investigated their interactions through a non-cooperative game. Finally, we studied the response of these interactions when fishing effort was restricted. We found that when the current fishing effort was maintained, the stock reduced to 26.4% of its capacity in 25 years. In addition, under non-cooperation, the traditional beach seine fleet exited the fishery. Interestingly, the constrained scenario had a coexistence output with increasing values for the final stock size and the per capita labour income, suggesting that limiting fishing effort can maintain all fishing gears in the fishery with social and ecological benefits.

Background Many educational technologies have been used to promote the health of the population. Thus, the objective was to assess the effect of using an individual educational primer along with the Brief Motivational Interviewing (BMI) for increasing maternal self-efficacy for preventing childhood diarrhoea. Methods Randomized clinical trial, conducted in Fortaleza/Ceará—Brazil, composed of 181 mothers and/or guardians of children under five years, who were randomized into three groups: experimental group A (EG A)—who read the primer, experimental group B (EG B)—application of the primer and BMI and the control group (CG). The participants' assessment was based on the Maternal Self-Efficacy Scale for Preventing Childhood Diarrhoea and the diarrhoea Investigation Form at the beginning of the intervention and then 30 and 60 days after the first contact with the participants. Results There were 60 participants in EG A and CG and 61 in EG B. It was noted a greater incidence of participants with high self-efficacy in EG B after applying the technologies. All groups manifested diarrhoea among children after the interventions, although with a lower number in EG B, one-month post-intervention (P  = 0.025). Conclusions The combined use of the primer and the BMI contributed significantly over time to increase maternal self-efficacy in preventing childhood diarrhoea and reduce cases of this disease.

This article introduces a rational expectations model that explains exchange rate dynamics and the predictability of forecast errors using private (aggregated via order flow) and public (probabilities of a binary event) information. We test the model for the periods leading up to the presidential impeachment vote in Brazil, the Brexit Referendum, and Donald Trump's election in 2016. Proxies of the physical probabilities of these events reveal that they are a crucial source of pricing information for the BRL, GBP, and MXN currency pairs with the US dollar. They also explain forecast errors. The information content of order flow changes before and after an actual regime change resolves uncertainty. [ABSTRACT FROM AUTHOR]
