The Quaternary vertebrate paleontology of the Brazilian Intertropical Region is well-known, but there are only a few publications on bone ichnology. In this paper, we analyzed trace fossils in 23 bones of the Gruna das Três Cobras, Complexo Suíço, and F3 caves, which are located in Bahia and Rio Grande do Norte states, in the Brazilian Intertropical Region. We discovered gnaw marks assigned to Machichnus and bite marks attributed to Nihilichnus, as well as insect modifications referring to single (Cuniculichnus, Gunnellichnus, Karethraichnus, and Osteocallis) and multiple behaviors (Munitusichnus, and Taotieichnus). Additionally, we proposed the new ichnospecies Nihilichnus sulcatus n. isp. (bite mark) and Cuniculichnus cascudoi n. isp. (insect feeding mark). Regarding the predation/scavenger marks, Protocyon troglodytes was the probable primary modification agent, but some traces may also be attributed to Smilodon populator and Caiman latirostris. Cuniculichnus, Karethraichnus, Munitusichnus, and Osteocallis are attributed to dermestids, whereas termites probably produced Gunnelichnus and Taotieichnus. [ABSTRACT FROM AUTHOR]

This paper examines how Chinese agribusiness firms are engaging with established systems of private governance in the Brazilian soybean sector and how that engagement is variously accommodated, contested, and configured by local realities that reflect the uneven history of transnational agribusiness development across the Brazilian agro‐export region. Using qualitative data collected at three research sites that represent different historical moments in the Brazilian agro‐export region (Mato Grosso, Goiás, and Bahia), the paper argues that the social structures underlying the particular agrarian histories of these three subregions create unique contexts Chinese firms must navigate, which in turn shapes their engagement with the private agribusiness regime across space. Although the private agribusiness regime is often portrayed as a top‐down system of governance that subjugates the polity to the demands of capital, this framing neglects to understand how that system of power is contested, negotiated, and reshaped on the ground. These three cases serve to historicize the uneven penetration of Chinese firms across the Brazilian soybean sector. [ABSTRACT FROM AUTHOR]

This paper aims to discuss how the public budget and the model of basic attention in public health could affect the infant mortality rates in a certain territory. The research was carried out in the Southern Coastal Territory of Bahia, in the State of Bahia, Northeast Region of Brazil. It is a quantitative and descriptive investigation, based on secondary data referring to the period from 2006 to 2015, collected between 2017 and 2018 in official Brazilian public data banks. It was verified that, although the average rate of infant mortality fell gradually from 2006 in the territory, it is still higher than the national average within the investigated period. In 2006, the average rate of the territory was 35.53% and decreased to 18.56% in 2015. However, throughout the period the average rate remained higher than the Brazilian average, which is 18%. Infant mortality rates have a strong relationship with social, economic, and environmental factors. In the case investigated, they are associated with the fragmentation and fragility of public health service networks in the municipalities of the region. [ABSTRACT FROM AUTHOR]

This paper provides descriptions and illustrations of two new species of Sapotaceae ( Pradosia longipedicellata and Chromolucuma apiculata) from Bahia, Brazil, a new combination ( Chromolucuma congestifolia), and a new identification key for Chromolucuma. Pradosia longipedicellata is distinguished from other congeners by its clustered fascicles of flowers on pedicels 2-3 cm long at the apices of the shoots, and a corolla that is 7-8 mm long. Chromolucuma apiculata is distinguished by glabrous shoots and leaves, short petioles (10-15 mm long), and stipules 5-8 mm long with apiculate apices, while its close relative C. congestifolia has a lower leaf surface with trichomes usually restricted to the midrib and stipules 3-6 mm long with acute apices. Due to intense deforestation in the Amazonian and the Atlantic forests, preliminary IUCN Red List assessments are provided. Pradosia longipedicellata and Chromolucuma congestifolia are proposed the IUCN status Vulnerable, while the data for C. apiculata are still insufficient (Data Deficient). [ABSTRACT FROM AUTHOR]

Abstract: This paper aims at establishing a tectonic and temporal framework to characterize the metallogenic processes that contributed to the origin of the mineral provinces in the northern São Francisco Craton. Many Archean mineralizations (eg. massive sulfide zinc, lead, zinc and copper, besides magnesite–talc, iron–titanium–vanadium, iron, chromite and manganese) were generated before the assembly of the Craton. Deposits of chromite, nickel, gold and emerald were produced during the Paleoproterozoic orogenic cycle, when the Craton was amalgamated into the Atlantica paleocontinent. An extension event is recorded in the Neoproterozoic, during the breakup of Rodinia, associated with deposits of phosphorite and uranium. Kimberlite diamond and gold mineralization were generated during the Brasiliano orogenic cycle, coeval with the amalgamation of West Gondwana. A long-lasting and rather uniform crustal stress is recorded in the area during the Cambrian period. Resetting of the isotopic and magnetic systems that affected the Neoproterozoic sediments of the Irecê Basin at about 520 Ma was attributed to the regional-scale fluid migration and mineralization in the aftermath of the Brasiliano orogenic cycle.

This paper depicts how an Afro-Brazilian carnival group turned community development organization addresses socioeconomic inequalities by educating a traditionally marginalized population as part of their larger goal of the preservation of black culture and full citizenship. Specifically, it examines the theory and practice of interethnic pedagogy, a unique approach to critical pedagogy specifically focused on incorporating the experiences and values of subaltern groups. Through ethnographic passages and analysis it examines their work in formal education at Escola Criativa Olodum in Salvador, Bahia and shows how Afro-Brazilian teachers, students and administrators engage in learning experiences while they strive to understand and redefine their own educational processes and outcomes. Lastly, through the lens of racial formation theory, it attempts to explain how these educators and activists periodically adjust their methods and considers their potential impact on Brazilian society.
