Como nasce uma política pública? Análise do processo de formulação da lei de migração
(Revistas Brasileiras Publicações de Periódicos e Editora Ltda., 2021-10) PEREIRA, Alan da Silva; MAGALHÃES, Allan Cavalcante Lira; SOUZA, Carlos Augusto da Silva; MACULUVE, Celeste Abel Cuad; GALVÃO, Jeniffer Walkiriam e Silva
The article investigates the process of formulating the new public policy to regulate the entry and stay of migrants in Brazil, Law 13.445, dated May 24, 2017, the Migration Law. We analyze how the problem has become relevant, the political cycles covered, and the formulation of the Law, identifying the political actors involved and institutions with veto power. The lawsuit was examined in the light of the arguments of Klaus Frey, John Kingdon and George Tsebelis.

Conversão tempo-profundidade de seções sísmicas empilhadas por raio imagem e raio normal
(Universidade Federal do Pará, 2014-06-24) REZENDE, Diogo Pena; CRUZ, João Carlos Ribeiro; http://lattes.cnpq.br/8498743497664023
In general, the oil industry makes the time-to-depth conversion of seismic data by the image ray tracing method. This method takes time into the depth, point to point, the amplitudes of the time migrated seismic section. For each point of the migrated time section, it is necessary to trace a ray perpendicular to the surface. After this, the amplitude of the migrated point of the section takes place in depth. The seismic migration method pre- or post-stack consists of placing seismic events in the correct positions in time or depth sections. Seismic depth sections provide an image near of the subsurface, in order to facilitate the identification of possible oil accumulating geological structures. The conversion of sections from the time to the depth domain is an intermediate step in the construction of seismic images in depth. This work developed and tested a method of converting time to depth the zero-offset seismic sections. In this case, the construction of sections in depth uses normal ray tracing method. The proposed method makes use of the (slowness versus time of intersection) transformation on the zero-offset section. Each point in the domain provides initial conditions for the normal ray tracing: a start position of the initial rays and initial angles formed with the normal to the surface, i.e., the slowness initial parameter. Unlike ray image method, several rays use the same travel time and the same initial position, defining an isochronous curve. The amplitude of each point in the zero-offset section takes place to depth from the distribution of values along each isochronous curve in depth. The image ray based time-to-depth conversion has good recovery of the depths of reflectors as well as low computational cost, since it is necessary only one ray to convert each point of the section in time. However, the reflector continuity may be damaged in case of sharpened curvature. In turn, by normal ray the time-to-depth conversion correctly approximate the depth of the reflectors, since the same point in time assigns several times in depth. However, it has a higher computational cost, because it is necessary many rays to convert one point in time.

Emigrados do sertão: secas e deslocamentos populacionais Ceará-Piauí (1877-1891)
(Universidade Federal do Pará, 2023-02-28) SILVA, Márcio Douglas de Carvalho e; LACERDA, Franciane Gama; http://lattes.cnpq.br/1007392320101957
In the second half of the 19th century, some provinces in the North of the Brazilian Empire faced successive droughts, which caused the migration of the population residing in the affected areas to others where it was believed that there were resources that would enable survival. In 1877, a drought began in Ceará that lasted until 1879. At the end of the 1880s, the phenomenon once again visited Ceará, leaving its visible marks, mainly in 1888 and 1889. great was the displacement of men and women from Ceará to other Brazilian provinces, including the neighboring one, Piauí, which to a certain extent was already affected by drought in the form of a climatic phenomenon, starting to experience it as a social product. The objective of this thesis is to analyze the migration of people from Ceará to Piauí, between the years 1877 and 1891, considering these displacements an act of protagonism by men and women, poor and rich, who undertook the migratory journeys as a possibility of overcoming the difficulties imposed by the dry in its place of origin, choosing Piauí as route and also destination. As a basis for the time frame, the year in which the flow of people from Ceará became more intense towards the neighboring province, until the beginning of the 1890s, when welfare practices were still carried out through public assistance, and it was already possible to find people from Ceará constituting new families in Piauí. Among the sources defined for carrying out the research, there are the different newspapers published in Piauí and Ceará, as well as reports, messages, speeches, minutes, as well as letters and other documents from the Public Aid Commission. Thus, this thesis investigates the fact that, in addition to the migratory flows that occurred in the 19th century, already known in historiography, there were other migrant destinations undertaken by people from Ceará, including Piauí, which was also affected by droughts, seen as a receiving pole, either for those who were destined for that region, as it offered better conditions for survival than Ceará, or for those who were trying to cross to Maranhão and Pará. Because it was intense at many times, migration brought to Piauí the worsening of the consequences of the drought, requiring measures to combat its effects by the local government, which established the Public Aid Commissions, promoting welfare and moving part of the migrants to the fronts of work, either in public works or in Colonial Nuclei. Upon arriving in Piauí, migrants almost always found it difficult to survive, however, many managed to settle in that region and did not return to Ceará after the end of the drought. In this way, the thesis of the importance of Piauí in the migratory contexts of the 19th century is defended, as a receiving space for migrants from Ceará and a generator of multiple social experiences.

O flagelado é o flagelo? Migração cearense e epidemias de varíola em Belém (1877-1915)
(Universidade Federal do Pará, 2024-02-26) SILVA, Julia Rafaela Silva da; VIEIRA JÚNIOR, Antonio Otaviano; http://lattes.cnpq.br/6764908679902300
This research aims to critically analyze the relationship between migration from the State of Ceará and smallpox epidemics in Belém, in the State of Pará, Brazil, from the second half of the 19th century to the early 20th century. The study seeks to contextualize the discourse of medical authorities and the press on the subject, attempting to unveil the reasons that led these entities to consider individuals from Ceará responsible for the smallpox epidemics. The fragility of these accusations, lacking substantiation, serves as a starting point to comprehend the connection between Ceará migrants and the smallpox epidemics that occurred in Belém during the Belle Époque. The interest in this topic arose from the observation of a certain consensus in the produced discourses, with significant alignment in the government authorities statements, doctors, and the press. This alignment resonated in the historiographical production addressing smallpox epidemics in Belém from the late 19th century to the early 20th century as will be shown later, with Arthur Vianna's thesis from the early 20th century thrived, that was the prevailing approach, becoming commonplace to explain the origin of smallpox epidemics in Belém during that period as a result of Ceará migration. The main objective here is to present the discourse of governmental authorities, doctors, and the press on the subject, aiming to understand its reasoning and potential questionings related to the positions of these entities. Since Vianna, this topic hasn’t been adequately addressed by historiography, deserving proper attention and investigative dedication.

Mobilidades geográfico-profissionais de duas gerações de agricultores familiares assentados na Amazônia oriental
(Museu Paraense Emílio Goeldi, 2016-04) SARTRE, Xavier Arnauld de; MARIN, Joel Orlando Bevilaqua; ASSIS, William Santos de; LOPES, Raquel da Silva; VEIGA JUNIOR, Iran Pereira
This article is about the new patterns of migration among farmer families in the eastern Amazon. These patterns were commonly framed as a strategy of social mobility, where moving was a way to acquire land. However, recent studies have shown that migration drivers are evolving because of social modernization and the rise of educational standards. While farmer families’ new strategies are well known, such as investing in education and moving to cities, little attention has been given to their quantification. By examining three “projetos de assentamento” (settlement projects) in the eastern Amazon, we wish to highlight the diversity of strategies that are used, and examine the way they relate to existing geographical and social settings.

NIP-tomografia usando método CRS e dados sísmicos marinhos
(Universidade Federal do Pará, 2013) AFONSO, João Batista Rodrigues; LEITE, Lourenildo Williame Barbosa; http://lattes.cnpq.br/8588738536047617
This work consisted on the application of techniques for processing, inversion and imaging of the Marmousoft synthetic data, and of the Jequitinhonha real data obtained on the eastern Atlantic continental shelf of the State of Bahia. The convencional NMO and CRS stack methods, and NIP-tomographic inversion were applied to the mentioned data. The NMO stack served to produce RMS and interval velocity distribution maps on the semblance domain. The CRS stack of both data we used for picking of re ection events to obtain the wave eld parameters that served to constrain the model as input for the NIP-tomographic inversion. The inversion characterizes as resulting in a smooth velocity model. Kirchhoff depth migration was used for verifying the obtained velocity models. We critically analyzed the applied techniques, and compared the CRS and the NMO stacks. The evolution of the visual quality of the obtained CRS and NMO sections were analyzed as measured by event continuity trace-by-trace and the signal/noise ratio. The di erences and improvements on the velocity model obtained by NIP-tomographic were also analyzed. The Kirchhoff prestack depth migration was applied aiming at geological interpretations, and to point out for better conditions of processing and imaging.

Para além da Baía de Guajará: migrações em Arapiranga e Ilha das Onças (1905-1950)
(Universidade Federal do Pará, 2024-01-19) SARMENTO, Enos Botelho; GUZMÁN, Décio Marco Antônio de Alencar; http://lattes.cnpq.br/0656841754619406; https://orcid.org/0000-0003-3219-4404
This work presents the migration dynamics between Belém and its island border (the island of Onças and the island of Arapiranga) in the first half of the 20th century (1905-1950). Through a historiographical and documentary critique, the aim is to explain the mobilities that led to the settlement of these varzeira regions following the arrival of migrants in the territories of Pará, to add this study to research on migratory movements in the Amazon estuary, rescuing the trajectories of foreigners, northeasterners and internal displacement, investigating in selected sources the origin of this population that currently resides in this estuary. The investigation seeks to contribute to Pará and Amazonian historiography to introduce the islands into historical perspective and reflections, refuting stigmatizing discourses about them, commonly imagined as regions empty of memory, with no interest in economic or political historical reflection.

Rumos, trechos e borocas: trajetórias e identidades camponesas de assentados rurais no sudeste do Pará
(Universidade Federal do Pará, 2006) BRINGEL, Fabiano de Oliveira; GUERRA, Gutemberg Armando Diniz; http://lattes.cnpq.br/4262726973211880
In this dissertation, we discuss the social and economics trajectory of peasants who live in the Project of Rural Settlement Palmares II, located in the brazilian city of Parauapebas, in the southeastern region of Pará. We focuss our analisys in four dimensions of the peasant’s life: the history of migration, the history of the family, the history of the work and the history of education. That way, we intend to establish nexuses and differentiations of economic, social, cultural and political contexts, which those peasants had passed before arriving in the occupation. We try this way to unmask forms and strategies of expropriation that are based on the social and economic disqualification of the peasant, which also are strategies to deny the tipical knowledge of the peasants, capable to guarantee the autonomy of the means of production and, then, threatening the possibilities of accumulation and consolidation of unsustainable economic activities in the Amazon region. The resistance to the disqualification and the requalification finds strenght in the peasant signs and practices, that these individuals keeps throughout generations, as the ownership and the work in the land, the essentially familiar workmanship, the autonomy of the means of production and a life style that values a more direct relation with the nature.

Solidarity through a network system: the case of indian migrants in marseille/France
(Universidade Federal do Pará, 2020-12) CORRÊA, Otávio Amaral da Silva
The urban environment is a space that increasingly encourages communication through virtual social networks. With the aim of thinking about the reality of migration and its relations with a solidarity built in a virtual environment, this article proposes to manage an ethnography with Indian migrants who live in the city of Marseille, region of Provence, southern France. How are these individuals who left India towards France organized? Through the ethnographic method, with techniques such as floating observation and participant observation, an anthropological study was carried out on a Facebook group and in Indian restaurants of the city. In this sense, the text seeks to demonstrate the construction of a social network system based on the feeling of solidarity and cooperation. Divided into two sections, the first part of the article tries to describe the relationships established in a Facebook group entitled “Indians in Marseille”. Afterwards, the text presents an ethnography of the relationships that structure the daily life of the Indian restaurants in the city, with the objective of analyzing the poles of power and the construction of solidarity
