This paper presents a successful application of the mise‐à‐la‐masse (MALM) or applied potential method in association with induced polarization (IP). MALM is known, since 1920, to be able to delimit electrically conductive massive mineralization. The method is used at the point where a drill hole intercepts a massive, mineralized body, to estimate its extent and shape. It is thus used as a complementary mineral exploration tool. IP is normally used in conjunction with resistivity. However, the acquisition of IP data together with the MALM method is rarely found in the literature. This survey shows that it is possible to successfully detect and delimit areas of disseminated sulphides using MALM with IP. In this paper, the MALM method is presented and discussed in detail. A short description of the IP method is also provided. Data are from the Camaquã Project (Caçapava do Sul, RS, Brazil) and the Santa Maria (lead, zinc and associated silver) deposit, 5 km south of Caçapava do Sul. In a well that intercepted a massive mineralization (borehole 8011) with electrical continuity, ∆V measurements delineated the extent, shape and orientation (NS) of a conductive sulphide body. Mineralization intercepted by other two wells (8011 and 8103) did not present enough electrical continuity to exhibit potential contours that could be associated to massive sulphides; it was, however, successfully detected by IP.

The origins of capitalism in Brazil have been traditionally overlooked by the literature on its developmental trajectory, either considered as an outcome of colonial exploitation or described through a broad notion of 'bourgeois revolution'. The recent discussion between the consequentialist interpretation of bourgeois revolutions and the Political Marxist critique of the bourgeois paradigm allows for a reassessment of these narratives, with a stronger emphasis on the specific disputes of early‐20th‐century Brazil. In this paper, I engage with Florestan Fernandes as the main representative of the bourgeois paradigm within Brazil. As an alternative, I present a reassessment of the 'capitalist transition' understood as a set of social property relations organised around market dependency. By tracing this form of market dependency through Brazilian historiography, I present a narrative that posits the development of capitalism in Brazil through the nonrevolutionary rise of an industrial bourgeoisie during the Old Republic and the competing strategies of declining (British) and rising (US/Germany) financial imperialism in the 1920s. Therefore, it highlights the role of (geo)political disputes by pointing towards the policy changes introduced by the Vargas regime in the 1930s as a key factor in the transition to capitalism in Brazil.

Abstract: This article studies the path dependence of human capital accumulation in the state of São Paulo, Brazil. It focuses on the impacts of German‐speaking immigrants on education through three channels: their share of the population in the nineteenth century, their on‐the‐job skills, and the schools they founded. Using a new dataset based on almanacs from 1873 and 1888, these effects are evaluated for the nineteenth, early twentieth, and early twenty‐first centuries. The article shows that the institutionalized demand for education of these immigrants, reflected by the establishment of schools, was their main contribution to the accumulation of human capital. The effect of German schools on educational levels required a period to mature and dissipated over time. Nevertheless, its influence was substantial at the beginning of the twentieth century, affecting enrolment levels in private and state schools, a result that suggests the existence of spillover and contagion effects. Moreover, current indicators for stocks and flows of human capital in São Paulo are strongly associated with their historical levels. At the same time, this path dependence is conditional on the type of school: while a positive persistence is found for the private system throughout the twentieth century, convergence occurred in state schools.

ABSTRACT This article assesses the meanings of the term 'historiography' in Brazilian historiography from the late nineteenth century to circa 1950, suggesting that its use plays an essential role in the process of the disciplinarization and legitimation of history as a discipline. The global-scale comparison, taking into consideration occurrences of the term in German, Spanish, and French, reveals that use of the term took place simultaneously worldwide. The term 'historiography' underwent a significant change globally, having become independent from the modern concept of history, shifting away from the political and social dimensions of the writing of history in the nineteenth century and unfolding into a metacritical concept. Such a process enables historians to technically distinguish at least three semantic modulations of the term: 1. history as a living experience; 2. the writing or narration of history; and 3. the critical study of historical narratives. Based on the Brazilian experience, it is possible to think of the 'historiography' category as an index of the transformations of the modern concept of history itself between the 1870s and 1940s, a period of intense modification of the experience and expectations of the writing of professional historical scholarship on a global scale.

ABSTRACT The history of human occupation in Brazil dates to at least 14 kyr BP, and the country has the largest record of early human remains from the continent. Despite the importance and richness of Brazilian human skeletal collections, the biological relationships between groups and their implications for knowledge about human dispersion in the country have not been properly explored. Here, we present a comprehensive assessment of the morphological affinities of human groups from East-Central, Coastal, Northeast, and South Brazil from distinct periods and test for the best dispersion scenarios to explain the observed diversity across time. Our results, based on multivariate assessments of shape and goodness of fit tests of dispersion and adaptation models, favor the idea that Brazil experienced at least two large dispersion waves. The first dispersive event brought the morphological pattern that characterize Late Pleistocene groups continent-wide and that persisted among East-Central Brazil groups until recently. Within the area covered by our samples, the second wave was probably restricted to the coast and is associated with a distinct morphological pattern. Inland and coastal populations apparently did not interact significantly during the Holocene, as there is no clear signal of admixture between groups sharing the two morphological patterns. However, these results cannot be extended to the interior part of the country (Amazonia and Central Brazil), given the lack of skeletal samples in these regions.
