[pt] A EXPERIÊNCIA PROFESSORTEXTO.BLOG: MEDIAÇÕES DO DESIGN NOS PROCESSOS INTERATIVOS DE ENSINO-APRENDIZAGEM PARA/COM ALUNOS DE GRADUAÇÃO EM COMUNICAÇÃO SOCIAL / [en] MEDIATION DESIGN IN THE INTERACTIVE PROCESSES OF TEACHING AND LEARNING FOR/WITH GRADUATE STUDENTS IN COMMUNICATION: PROFESSORTEXTO.BLOG EXPERIENCELUIZ FERNANDO FAVILLA CARRILHO 23 November 2021 (has links)
[pt] Partindo da premissa de que Design é o processo de pensamento que compreende a criação de alguma coisa (Miller, 1988), realizei uma pesquisa-ação participante com alunos do terceiro período da graduação em Comunicação Social da Pontifícia Universidade Católica do Rio de Janeiro, sobre processos interativos de ensino-aprendizagem vinculados às Novas Tecnologias Digitais de Informação e Comunicação (NTDICs). Como professor regente de três turmas da disciplina Técnicas de Comunicação II, desenvolvi, como ferramenta de mediação, o professortexto.blog, uma interface digital de interação entre professor e alunos participantes. O presente trabalho descreve e analisa a experiência interdisciplinar vivida pelos participantes em sala de aula presencial e virtual, simultaneamente. E conclui que professores gestores das NTDICs exercem a função de designers cognitivos a projetar e manter pontes dialógicas para orientar projetos e direcionar pesquisas que os universitários terão que produzir para conhecer. / [en] Starting from the premise that design is a thinking process comprising the creation of an entity, according to Miller (1988), I have conducted a participatory research with third semester undergraduate students of Social Communications at the Pontifical Catholic University of Rio de Janeiro . The research is focused on interactive processes of teaching/learning linked to the New Digital Technologies for Information and Communication (NTDICs). As a professor of three classes of Communication Skills II, I have developed the professortexto.blog as a mediation tool, which has provided me with a digital interface to interact with my students. This work describes and analyzes the interdisciplinary experience lived, simultaneously, by the participants in the classroom and virtual ly. It concludes that teachers who manage NTDICs play the role of cognitive designers as they are supposed to plan and maintain dialogical bridges to guide and direct the students’ research projects in order to develop their knowledge.

A Historical Approach to Shifting Technologies of Ceramic Manufacture at Gaspereau Lake, Kings County, Nova ScotiaWoolsey, Cora A. January 2018 (has links)
A lengthy history (1550–950 Cal BP) of ceramic manufacture took place at the Gaspereau Lake Reservoir (GLR) Site Complex in Kings County, Nova Scotia, during which potters shifted their practice from fineware, emphasizing self-expression and signalling affiliation, to “production” pottery, focusing on quick turnaround times and larger scale of production. Researchers in the Maine–Maritimes Region have repeatedly noted the change from hard-bodied, thin-walled, elaborately and carefully decorated pots during the Middle Woodland to coarser-tempered, expediently decorated pottery with many coil breaks evident during the Late Woodland. This has sometimes been interpreted as a decreasing skill level through time, but I argue that these changes instead suggest a manufacturing context in which demand for pottery increased. This created incentives for “cutting corners” and employing strategies that increased the survival rate of pots during firing. Increased production is partly evident in increasing standardization of temper minerals and clay later in time, suggesting that potters increasingly accessed a single reliable source of raw materials rather than many different sources. I further argue that manufacturing occurred at or near the End of Dyke Site.
I present a method of analyzing ceramics that is designed to take full account of the unusually large and nuanced GFC assemblage. This method goes beyond chronological and typological classifications that have sometimes been employed in the Northeast: it seeks to establish a historical understanding of the assemblage through tracing learning lineages. This classification, which I have called a “tradition-based classification,” introduces knowledge transfer as the dominant mechanism behind style at the level of assemblage. The ceramics have been grouped using attribute analysis, after which inferences about the variability have been assessed, and finally, several trends—chronologically situated using AMS dates—are proposed to build a history of ceramic manufacture at Gaspereau Lake. / Thesis / Doctor of Philosophy (PhD) / Ceramics are one means of analyzing the practices of ancient cultures. Ceramics allow archaeologists to trace developments through time. This dissertation looks at how other sources of information are available to archaeologists by carefully tracing the evolution of certain characteristics through time. Some characteristics explored in this dissertation include the changing methods of manufacturing ceramics and the changing materials used by ancient potters. I conclude that ceramic production increased later in time, and that this change probably indicates a change in the larger society as pottery became increasingly in demand.

Spatial Analysis of Selected Reproductive Health Outcomes of Women Living in the Vicinity of the Sydney Tar Ponds, Sydney, NSDeluca, Patrick 11 1900 (has links)
Decades of steel production and coking in the community of Sydney, Nova Scotia, have led to severe environmental insult. Increased amounts of air pollution from Sydney Steel Corporation and toxic emissions from the Muggah Creek Watershed have been well documented in several studies of the area since the 1960s. This research examines the potential impacts of exposure to hazardous waste on the reproductive health of women living in Cape Breton Regional Municipality through the following objectives: i) to assess the spatial pattern of various types of adverse reproductive events, plausibly linked to the environmental exposure of interest; ii) to determine if this pattern is related to proximity to the Tar Ponds/Coke Ovens site. To address the first objective, point pattern analysis was applied to observations from the Atlee Perinatal Database to determine if the observed pattern exhibited any clustering. To address the second objective, a multinomial logistic regression model was employed to determine if proximity to the Tar Ponds/Coke Ovens site was an important covariate of the adverse outcomes under study (preterm births, low birthweights, congenital anomalies and stillbirths). The results of the bivariate K-function indicated that there was weak global clustering for preterm births for two different time periods, while the ratio kernel estimates demonstrated that the patterns of the outcomes were non-random even after correcting for the underlying population distribution. The results of the multinomial logistic model demonstrated that variables pertaining to maternal characteristics, pregnancy history, current pregnancy maternal diagnoses, neonatal measures were important explanatory variables in the analysis. Place of residence was an important explanatory variable for preterm births and congenital anomalies. However, due to various limitations these results must be interpreted with caution. / Thesis / Master of Arts (MA)

Are Cooking Interventions Effective at Improving Dietary Intake and Health Outcomes? A Systematic ReviewWunderlich, Kayla Marie 14 September 2022 (has links)
Existing systematic reviews have suggested that cooking interventions can be beneficial for improving dietary intake and health outcomes, with research indicating that the ability to prepare meals at home may prove to be more complex, and involve influencing factors (i.e., cooking self-efficacy, food agency [i.e., one's ability to procure and prepare food with the considerations of their physical, social and economic environment], and nutritional literacy/knowledge) for improving health outcomes. With the average American's diet consisting of about 60% of total energy coming from the consumption of ultra-processed foods, interventions that target increasing cooking skills and the frequency of consuming home-cooked meals may help to reduce reliance on processed foods, improve dietary intake quality, and reduce risk of weight gain, obesity, and related conditions. To date, there are no systematic reviews that have addressed the impact of cooking interventions on processed or ultra-processed food consumption. Therefore, this research systematically reviewed the body of literature focused on cooking interventions and dietary intake including processed food consumption and evaluated intervention's effectiveness at improving dietary intake and physical and mental health outcomes. English and full-text research articles published through January 2021 were obtained through PubMed, CINAHL using EBSCO, Web of Science from Clarivate, Scopus and PsycInfo.
Overall, 55 articles were obtained after meeting the inclusion criteria and going through the data extraction process. Outcomes of interests to measure included fruit and vegetable consumption, body mass index (BMI), body weight, waist circumference, blood pressure, physical activity, and if the study measured psychosocial outcomes or processed food consumption. Results indicate that when analyzing the effect sizes for studies that reported mean data for each group (eg, intervention and control/comparison groups), 86% of studies measuring fruit intake found a positive effect size (Average: Cohen's d: 0.65, 95% CI: 0.30, 0.99); 90% of studies measuring vegetable intake found a positive effect size (Average: Cohen's d: 0.80, 95% CI: 0.37, 1.09); 82% of studies measuring BMI found a negative effect size (Average: Cohen's d: -0.20, 95% CI:
-0.58, 0.17); 100% of studies measuring body weight had a negative effect size (Average:
Cohen's d: -0.27, 95% CI: -0.77, 0.23); and 100% of studies measuring waist circumference had a negative effect size (Cohen's d: -0.16, 95% CI: -0.60,0.24). This systematic review will provide information on recently published studies that were not incorporated in prior reviews that can be utilized in future interventions that aim to improve health outcomes and reduce processed food consumption. / Master of Science / Prior systematic reviews have stated that cooking classes and demonstrations may be beneficial for improving an individual's diet and overall health. Research currently suggests that the ability to prepare meals at home may prove to be more difficult to assess, and involve other factors, (i.e., cooking confidence, one's ability to get and prepare food in their physical, social and economic environment, and nutritional knowledge) for improving physical and mental health. With the average American's diet consisting of about 60% of total energy coming from the consumption of ultra-processed foods, interventions that aim to improve cooking skills and how often someone consumes home-cooked meals may help to reduce reliance on processed foods, improve diet quality, and reduce risk of weight gain, obesity, and related conditions. To date, there are no systematic reviews that have explored cooking interventions effects on ultra-processed food consumption. This research systematically reviewed the body of literature focused on cooking interventions and dietary intake including processed food consumption and evaluated their effectiveness at improving dietary intake and physical and mental health outcomes. English and full-text research articles published through January 2021 were obtained through five online databases. Overall, 55 articles were included. Outcomes of interests included fruit and vegetable consumption, body mass index (BMI), body weight, waist circumference, blood pressure, physical activity, psychosocial outcomes, and processed food consumption. Results indicate that 86% of studies measuring fruit intake found their intervention to be effective in increasing fruit intake. A total of 90% of studies measuring vegetable intake found that their interventions were effective at improving vegetable intake. 82% of studies measuring BMI found that their interventions showed effectiveness at decreasing BMI. Both 100% of studies measuring body weight and waist circumference showed effectiveness at decreasing both measures. This systematic review will provide information on recently published studies that were not incorporated in prior reviews that can be utilized in future interventions that aim to improve health outcomes and reduce processed food consumption.

Variable water pressure metamorphic assemblages in the Meguma Group, Nova ScotiaSage, Janet D. January 1984 (has links)
Amphibolite grade pelites from the Buchan type metamorphism of the Meguma Group in southwestern Nova Scotia contain the assemblage And+Grt+Bt+Q+Pl+Ms+Ilm+Mgt±St±Crd±Sil±Po±Py. Grt-Bt geothermometry and Pl-Grt-And-Q geobarometry on samples from three widely separated 3-8 km traverses yield temperatures and pressures that cluster in two groups; (1) two traverses near Shelburne with T=500-510°C and P=3.5 kbar; and (2) one traverse on the West Pubnico peninsula, 40 km to the southwest, with T=530-560°C and P=1.5-2. 5 kbar. P<sub>H₂O</sub> estimates based on Ms-and-Pl-V assemblages indicate that P<sub>H₂O</sub> = .4-.9 P<sub>Total</sub> for rocks from the Shelburne area and P<sub>H₂O</sub>=P<sub>Total</sub> for the rocks south of West Pubnico.
Whole rock chemical analyses on samples from the three traverses show no systematic variations over the region. In the Pubnico traverse, the presence or absence of staurolite is dependent both on slight variations in the Fe/Mg ratios of the rocks and on temperature differences. In the staurolite-bearing rocks the assemblages and mineral chemistries indicate that the systems represent divariant continuous reactions and contain cordierite only where P<sub>H₂O</sub> < P<sub>Total</sub>. Thus the large number of phases is neither the result of disequilibrium nor representative of a low variance assemblage, but can be described as a divariant assemblage involving 8 to 9 major components. / Master of Science

A synopsis of Philippine Cyrtandra (Gesneriaceae)Olivar, Jay Edneil C., Atkins, Hannah J., Bramley, Gemma L.C., Pelser, Pieter B., Hauenschild, Frank, Muellner-Riehl, Alexandra N. 02 May 2024 (has links)
A taxonomic synopsis of Philippine Cyrtandra (Gesneriaceae) is presented. Following a study of 138 published names and
their types, we accept 98 Cyrtandra species for the Philippine flora. Except for C. angularis, C. elatostemoides, and C. yaeyamae, all
are endemic to the country. Lectotypes or neotypes are designated for all names for which this is necessary, except for six names for
which we were unable to locate original material. We also validate a species name that was previously described without a Latin diagnosis
(C. peninsula), synonymize three names, and provide taxonomic notes for each species. In addition, we propose two replacement
names for taxa for which a legitimate name in Cyrtandra does not currently exist: C. edanoi for a Philippine species and
C. siporensis for a Sumatran species. A look-up table is provided to facilitate referencing of currently accepted names in Philippine Cyrtandra.

Analýza zvukové, obrazové a obsahové složky ve sportovním zpravodajství (na příkladě sportovních relací Branky, body, vteřiny na České televizi a Sportovní noviny na TV Nova) / Analysis of sound, visual and content components in sport broadcasting (on example of sport coverages Branky, body, vteřiny on Czech TV and Sportovní noviny on TV Nova)Prouza, David January 2016 (has links)
In the beginning of the theoretical part this diploma thesis deals with the history of television broadcasting with emphasis on sport content. It continues with analysis of sport news programs Branky, body, vteřiny and Sportovní noviny and deals with their history and progress. In the theoretical part there are also presented visual and sound elements of TV broadcasting (such as shot composition, axis rule, sound, rush etc.). There is also introduced complete process of making television sport story from redactor's point of view. Practical part of the thesis contains, due to the periodic recording of the two sport programs, the presentation of current structure and shape of shows Branky, body, vteřiny and Sportovní noviny. Both programs are processed from the technical point of view (working with cameras in the studio and outside of the studio, working with sound track, expression and pronunciation of anchormen and redactors etc.) as well as from the content point of view, where there is showed three-week analysis of each broadcast day. The analysis is trying to show technical differences between the shows, as well as to present what is their overall structure and also which sports they present the most.

Estudo Paleomagnético de Unidades Paleoproterozóicas do Cráton Amazônico / Paleomagnetic Study of Paleoproterozoic Units from Amazonian CratonSantos, Franklin Bispo dos 03 May 2012 (has links)
Na América do Sul, o Cráton Amazônico representa um componente essencial nas reconstruções de supercontinentes, entretanto, há uma grande escassez de dados paleomagnéticos de qualidade para esta unidade geotectônica, principalmente, para o Proterozóico. Com o intuito de esclarecer a participação do Cráton Amazônico na evolução do ciclo continental, este trabalho apresenta um estudo paleomagnético realizado em quatro unidades geológicas Paleo- a Mesoproterozóicas pertencentes ao Cráton Amazônico. As unidades escolhidas para este estudo foram às rochas vulcânicas do Grupo Surumu (1980-1960 Ma, U-Pb), as soleiras máficas Avanavero (ca. 1780 Ma, U-Pb) ambas situadas no norte do Estado de Roraima (Escudo das Guianas), os enxames de diques Nova Guarita e a intrusiva máfica Guadalupe ambas localizadas no norte do Estado do Mato Grosso (Escudo Brasil-Central). Determinações 40Ar/39Ar realizadas em biotitas de quatro diques de Nova Guarita mostraram resultados coerentes, fornecendo uma idade média de 1418,5 ± 3,5 Ma para a época de intrusão dos diques. Idades U-Pb obtidas em rochas da intrusiva máfica Guadalupe indicam uma idade mínima de 1530 Ma para estas amostras. As análises paleomagnéticas realizadas em mais de 1100 espécimes de rocha através dos tratamentos térmicos e por campos magnéticos alternados revelaram direções características coerentes para as quatro unidades de rochas estudadas: (1) as rochas do Grupo Surumu apresentaram direções noroeste com inclinações positivas. Foi calculada uma direção média Dm = 298,6°, Im = 39,4° (N = 20, alfa95 = 10,1°, K = 11,4), a qual foi interpretada como sendo de origem primária; (2) as rochas máficas Avanavero apresentaram direções sudeste com inclinações positivas/negativas baixas, sendo determinada uma direção média Dm = 135,6°, Im = -2,1° (N = 10, alfa95 = 15,9°, K = 10,2°). Um teste de contato cozido realizado para um dos sítios amostrados atesta o caráter primário da magnetização remanente isolada, a qual foi adquirida pelas rochas há ca.1780 Ma atrás; (3) os diques máficos Nova Guarita apresentaram polaridades reversas e normais, tendo sido isoladas direções sul/sudoeste com inclinações positivas e nordeste com inclinações negativas. Um teste de contato cozido positivo foi obtido para um dique que intrude o Granito Matupá, o qual confirma que a magnetização remanente (Dm = 220,5°, Im = 45,9°, N = 19, alfa95 = 6,5°, K = 27,7) isolada para estas rochas corresponde a uma magnetização termorremanente adquirida durante a formação da rocha há ca. 1419 Ma atrás; (4) rochas pertencentes a Intrusiva Máfica Guadalupe também apresentaram polaridades reversas e normais. Direções noroeste/nordeste com inclinações positivas ou sul/sudeste com inclinações negativas foram isoladas para estas rochas, para as quais foi calculada a direção média Dm = 356,6°, Im = 59,4°, (N = 10, alfa95 = 10,2°, K = 23,2). A idade desta componente, entretanto, ainda não está bem estabelecida, podendo representar uma remagnetização adquirida durante o evento Brasiliano, já que ela é similar às magnetizações adquiridas há 520 Ma, presentes em formações geológicas do Cráton Amazônico e do Cráton do São Francisco. A caracterização da mineralogia magnética de todas as amostras investigadas foi obtida através de curvas termomagnéticas, curvas de histerese e curvas de magnetização remanente isotérmica. Quatro pólos paleomagnéticos para o Cráton Amazônico foram determinados para estas componentes, os quais estão localizados em 234,8° E, 27,4°N (A95=9,8°) (pólo GS, Grupo Surumu), 27,5°E, -45,8°N (A95=11,5°) (pólo AV, Avanavero), 245,9°E, -47,9°N (A95=7,0°) (pólo NG, Nova Guarita) e 306,2°E, 38,9°N (A95=13,7°) (pólo GUA, Guadalupe). Os resultados paleomagnéticos obtidos para as rochas Surumu (pólo GS) contribuíram para um melhor ajuste da curva de deriva polar aparente (CDPA) para o Escudo das Guianas durante o Paleoproterozóico (2070-1960 Ma). A comparação desta CDPA com a construída para o Cráton Oeste-África para o mesmo período de tempo sugere que estes blocos cratônicos estavam unidos há 1970-2000 Ma atrás, em uma paleogeografia em que as zonas de cisalhamento Guri, no Escudo das Guianas, e Sassandra, no Cráton Oeste-África estavam alinhadas como sugerido em modelos anteriores. O pólo Avanavero de 1780 Ma é consistente com a paleogeografia do supercontinente Columbia em que o proto-Cráton Amazônico e a Báltica estavam unidos como no modelo SAMBA (South America-Baltica) proposto anteriormente com base em evidências geológicas. No cenário proposto aqui para o Supercontinente Columbia há 1780 Ma atrás, o Cráton Oeste-África estava unido ao proto-Cráton Amazônico na mesma configuração sugerida pelos dados paleomagnéticos de 1790-2000 Ma. O atual lado leste da Laurentia estava unido ao norte (atual) da Báltica. A Sibéria estava unida com a atual costa Ártica da Laurentia e a proto-Austrália, com a atual costa oeste da Laurentia, em posição similar ao modelo SWEAT. Embora os dados paleomagnéticos disponíveis para o Cráton Norte da China e Índia indiquem paleolatitudes equatorias para estes dois blocos, nesta época, suas posições no supercontinente Columbia são ainda incertas. No modelo do Columbia apresentado neste trabalho, o Norte da China foi colocado ao lado da Sibéria e a Índia, ao lado da proto-Austrália, em decorrência de evidências geológicas. Outros blocos cratônicos, tais como, Congo-São Francisco, Kalahari e Rio de La Plata não foram incluídos, pela ausência de pólos paleomagnéticos desta idade. Os dados paleomagnéticos atualmente existentes para a Báltica e a Laurentia mostram que estes dois blocos continentais permaneceram unidos desde 1830 Ma até, pelo menos, 1270 Ma atrás. Já o pólo paleomagnético obtido para os diques Nova Guarita de 1419 Ma e o pólo de mesma idade, recentemente obtido para a Intrusiva Indiavaí, quando comparados com pólos de mesma idade da Báltica e da Laurentia, sugerem que o proto-Craton Amazônico já havia iniciado sua ruptura no Supercontinente Columbia nessa época. De modo alternativo, porém, essa diferença na posição dos pólos do proto-Cráton Amazônico e da Báltica/Laurentia, pode ser explicada por movimentos transcorrentes dextrais que teriam ocorrido entre o Escudo das Guianas e a parte sul do Cráton Amazônico em tempos posteriores a 1420 Ma. Neste caso, esta grande massa continental do Supercontinente Columbia, composta pelo proto-Cráton Amazônico, Báltica e Laurentia, pode ter permanecida unida por, pelo menos, 400 Ma. / The Amazonian Craton is an important component in Paleoproterozoic reconstructions, however, paleomagnetic data for this craton are yet scarce. Aiming to decipher the involvement of the Amazonian Craton in the Contiental cycle evolution, paleomagnetic studies were carried out in four Paleo- to Mesoproterozoic geological units. The chosen units are the volcanic rocks from the Surumu Group (1,980-1,960 Ma, U-Pb), the Avanavero mafic sills (ca. 1,780 Ma, U-Pb), both from the northern Roraima State (Guyana Shield), and the Nova Guarita dyke swarm and Guadalupe mafic intrusive, both from the northern Mato Grosso State (Central- Brazil Shield). 40Ar/39Ar determinations on biotites from samples belonging to four Nova Guarita dykes yielded well-defined plateau ages whose mean 1,418.5 ± 3.5 Ma is interpreted as the age of dyke intrusion. U-Pb (SHRIMP) determinations on rocks from the Guadalupe mafic Intrusive indicate a minimum age of 1,530 Ma for this unit. Paleomagnetic analysis performed on more than 1,100 specimens by thermal and alternating magnetic field (AF) treatments revealed stable characteristic remanent magnetizions (ChRM) for all geological units: (1) northwestern directions with positive inclinations were isolated for samples from the Surumu Group (mean: Dm = 298.6°, Im = 39.4°, N = 20, alpha95 = 10.1°, K = 11.4), which were interpreted to be primary. (2) Southeastern directions with low downward/upward inclinations were isolated for the Avanavero rocks, for which a mean direction was calculated: Dm=135.6°, Im = -2.1° (N=10, alpha95 = 15.9°, K = 10.2°). A positive baked contact test attests for the primary origin of this ChRM direction, which was probably acquired at about 1,780 Ma ago; (3) both south/southwestern directions with downward inclinations or northeastern directions with upward inclinations were isolated for the Nova Guarita dykes. A positive baked contact test attests for the primary nature of the ChRM directions (Dm = 220.5°, Im = 45.9°, N=19, alpha95=6.5°, K = 27.7) which most probably correspond to a termo-remanent magnetization (TRM) acquired at ca. 1,419 Ma ago; 10 (4) both northwest/northeastern directions with downward inclinations or outhsoutheastern directions with upward inclinations were isolated for rocks from the Guadalupe intrusive, whose mean direction is: Dm=356.6°, Im=59.4°, (N =10, alpha95=10.2°, K = 23.2). The age of this component is yet uncertain. U-Pb geochronology suggests an age of (or older than) 1,530 Ma for these rocks, however, a remagnetization effect at Cambrian times (520 Ma) cannot be rolled out as these directions are very similar to those found for younger geological units in the Amazonian Craton and Sao Francisco Craton. Four new paleomagnetic poles for the Amazonian Craton were obtained from these magnetic components, which are located at: 234.8°E, 27.4°N (A95=9.8°) (GS pole, Surumu Group), 27.5°E, 45.8°S (A95=11.5°) (AV pole, Avanavero), 245.9°E, 47.9°S (A95=7.0°) (NG pole, Nova Guarita) and 306.2°E, 38.9°N (A95 = 13.7°) (GUA pole, Guadalupe). The 1,960 Ma Surumu pole contributes to better define the APW path traced for the Guyana Shield in the time interval between 2,070 Ma and 1,960 Ma. Comparison of this APW path with that traced for West-Africa Craton for the same time interval suggests that these two cratonic blocks were linked together, in a paleogeography where the Guri (Guyana Shield) and Sassandra (West-Africa Craton) shear zones are aligned, as suggested by previous models. The Avanavero pole is consistent with the proto-Amazonian Craton and Baltica link as in the SAMBA (South America-Baltica) model at ca. 1,780 Ma ago, as previously proposed based on geological evidence. In the scenario proposed here for the Columbia Supercontinent at 1,780 Ma ago, the West-Africa Craton was linked to the proto-Amazonian Craton in the same configuration as suggested by Paleoproterozoic (1,960-2,000 Ma) paleomagnetic data (see above). Actual eastern Laurentia was linked to northern Baltica. Siberia was located at the actual Arctic Coast of Laurentia, and proto-Australia at the western coast of Laurentia, in a position similar to that of SWEAT model. Although available 1,780 Ma paleomagnetic data from North China and India indicate low paleolatitudes for these two blocks, their positions in the supercontinent Columbia are yet uncertain. In our model, North China is located beside Siberia, and India beside proto-Australia, based on geological evidences. Other cratonic blocks, such as Congo-Sao Francisco, Kalahari and Rio de la Plata were not included as no 1,780 Ma paleomagnetic poles are presently available for them. The paleomagnetic poles presently available for Baltica and Laurentia, show that these two blocks remained as a single continental mass since 1,830 Ma up to at least 1,270 Ma. However, the 1,419 Ma Nova Guarita pole and the recently published 1,416 Ma Indiavai pole from the Amazonian Craton, when compared with poles of similar age from Baltica and Laurentia suggest that the proto-Amazonian Craton had already broke-up from the Columbia Supercontinent at that time. Alternatively, the difference in the position of the 1,420 Ma poles from the proto-Amazonian Craton and those from Baltica/Laurentia, may be explained by dextral transcurrent movements between the Guyana Shield and the southern part of the Amazonian Craton at times later than 1,420 Ma. If so, this great continental mass, formed by proto-Amazonian Craton, Baltica and Laurentia may have remained as a single continental block for at least 400 Ma.

Previous issue date: 2018-09-17 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This research deals with the reality of the territorial context of the Vila Nova neighborhood in the municipality of Registro-SP. In the face of complexities we perceived, we sought to reflect on how particular are the expressions of social issues in that territory. Therefore, a brief literature review on the capitalist mode of production and the production and reproduction of unequal social relations was necessary. Within this discussion it was possible to think the role that the state plays in this context. The territory was presented through data, participant observation and research subjects’ narratives, which enabled an analysis of the social locus that it takes in the municipality and in the capitalist system. It reveals a territory affected by poverty, stigma, limited or no access to rights, police violence and a high incarceration rate. By discussing the relationship between the state and "social issues" through the life stories of the research subjects, it is possible to reconcile macro- and micro-level analysis presenting how this relationship occurs both in the broader capitalist context and in the particular context of Vila Nova and considering the conditions for the high incarceration rate of its residents. In the narratives of the subjects, the potentialities and possibilities of the territory become evident, demonstrating that Vila Nova is a place of many struggles and resistances / A presente pesquisa trata de leitura da realidade do contexto territorial do bairro Vila Nova no município de Registro/SP. Diante das complexidades percebidas, buscou-se refletir sobre como as expressões da questão social particularizam-se no território. Para tanto, foi necessária breve revisão bibliográfica sobre o Modo de Produção Capitalista e sobre a produção e reprodução de relações sociais desiguais. Dentro desta discussão foi possível pensar o papel ocupado pelo Estado neste contexto. A apresentação do território, realizada através de dados, observação participante e das narrativas dos sujeitos da pesquisa, permitiu analisar o local social que o território ocupa dentro do município e do sistema capitalista. Revela um território marcado pela pobreza, pelo estigma, pelo não acesso ou acesso precário a direitos, pela violência policial e pelo alto índice de encarceramento. Através das histórias de vida dos sujeitos da pesquisa é possível, ao tratar da relação entre o Estado e “questão social”, conciliar análise macro e micro ao apresentar como esta relação se dá tanto no contexto capitalista mais abrangente quanto no contexto particular da Vila Nova, e assim, pensar as condicionantes para o elevado índice de encarceramento de seus moradores. Nas narrativas dos sujeitos as potencialidades e possibilidades do território se evidenciam demonstrando que a Vila Nova é um local de muitas lutas e resistências
