REFLEXÕES SOBRE A HIPERSPECIALIZAÇÃO CIENTIFICA E SUAS CONSEQUÊNCIAS PARA A GEOGRAFIA
Authors: Gonçalves Junior Francisco De Assis , Corrêa Thamires Cristine 
Published: January 2018

Este artigo visa discutir o contexto histórico e filosófico responsável pela origem do conceito que Edgar Morin define em sua obra A cabeça bem–feita: repensar a reforma, reformar o pensamento como, a "hiperspecialização" da análise científica, ou em outras palavras, a especialização que se fecha em si mesma, que fragmenta a realidade e que impede o pesquisador de conceber o global. Considerou-se como premissa que a origem desta segregação analítica advém das formas de pensamento oriundas da supervalorização da razão humana. Para análise desta conjectura foram considerados dois pensadores: René Descartes e Isaac Newton. Apresentaremos também algumas reflexões sobre a problemática da hiperespecialização científica na análise geográfica, principalmente no que tange a hiperespecialização organizada em torno da matemática/geometria, uma vez que a Geografia, devido a seu objeto de estudo (relação homem-sociedade/natureza), possui sua construção epistemológica pautada em questionamentos complexos e até mesmo subjetivos, ou seja, situações que demandam formas de análise multidimensionais, e que portanto, não apresentam coesão quando demasiadamente fragmentadas. Neste bojo, considera-se que a atuação de profissionais hiperespecializados (tanto licenciados como bacharéis) tem diluído a unidade da Geografia enquanto ciência voltada a uma compreensão ampla da realidade social. Palavras-chave: História da Ciência, hiperespecialização, epistemologia da Geografia

Claus Emmeche: “Do You Tell Me? Knowledge about Friendship in Literature and Scholarship” Friendship as an interpersonal relation is discussed through the perspective of history of knowledge as a historically contingent relation that can be modelled in fiction, literature, and different academic disciplines, like for instance philosophy, anthropology, and history. The opposing claims of philosopher Alexander Nehamas and literary critic Gregory Jusdanis on the adequacy of the novel to describe friendship is discussed, partly drawing on literary friendship studies by Janet Todd and Victor Luftig. Starting from the Neapolitan Novels by Elena Ferrante (depicting a difficult, close, life-long friendship between two women and the precarious knowledge emerging from this relationship) and recent scholarship on Ferrante’s work, the article shows how these novels are not just inspired by but also comment critically upon the work on narrative friendship by philosopher Adriana Cavarero.

No cenário atual de expansão, interação e complementaridade das unidades que formam as aglomerações urbanas, intensificam-se as formas de mobilidade interurbana que não implicam em mudança de residência e que se caracterizam por sua regularidade. Este estudo analisa os movimentos pendulares para estudo e trabalho na RMGV, buscando investigar transformações, permanências e desafios da mobilidade espacial na região nas últimas décadas. São utilizadas várias fontes de dados e informações, em especial os dados censitários produzidos pelo Instituto Brasileiro de Geografia e Estatística (IBGE), tratados por métodos estatísticos para a construção de indicadores e pela aplicação do Sistema de Informação Geográfica para a representação cartográfica. A RMGV, que concentra população e infraestruturas sociais e produtivas, se destaca pelo dinamismo dos movimentos pendulares. A reprodução interna das diferenças socioeconômicas resulta em fluxos fortemente direcionados para o Polo Vitória, seguido por Vila Velha, Serra e Cariacica, que apresentam elevado nível de integração na dinâmica metropolitana. ABSTRACT In the current scenario of expansion, interaction and complementarity of the units that form urban agglomerations, interurban mobility patterns that do not imply change of residence and which are characterized by their regularity are intensified. This paper analyzes commuting for study and work in the RMGV, seeking to investigate transformations, permanences and challenges of spatial mobility in the region throughout the last decades. Several sources of data and information are used, specially census data from the Brazilian Institute of Geography and Statistics (IBGE), treated by statistical methods in order to construct indicators and by the application of the Geographic Information System (GIS) for cartographic representation. The RMGV, which concentrates population as well as social and productive infrastructure, stands out by its commuting dynamism. The internal reproduction of socioeconomic differences result in flows strongly directed to Vitoria, followed by Vila Velha, Serra and Cariacica which present a high level of integration in the metropolitan dynamic.

RESUMENEl escenario actual de la migración entre México y Estados Unidos presenta características nunca antes vistas. Una desaceleración del flujo migratorio hacia el norte y un retorno inesperado de mexicanos a sus comunidades de origen. Sin embargo, al mismo tiempo y sin tomar en cuenta los hechos, en la política migratoria y en el discurso se intensifica el control de la frontera y se manifiesta la necesidad de expulsar al mayor número de mexicanos indocumentados. En este artículo, se analizan las tendencias demográficas de la fuerza laboral con una perspectiva binacional y longitudinal a través de la construcción de un semi-panel. Los resultados muestran tendencias convergentes en ambas poblaciones hacia un paulatino envejecimiento, la concentración de mexicanos en Estados Unidos en edades adultas jóvenes y el retorno de mexicanos en todos los grupos de edad al mercado de trabajo. Además, muestra la persistente segmentación del mercado de trabajo estadounidense y la vulnerabilidad a la que se enfrentan los retornados en México. ABSTRACTThe current scenario of the migration between Mexico and the United States has characteristics never seen before. A decelerating migratory flow towards the north and an unexpected return of Mexicans to their communities of origin. At the same time and without taking into account the facts, immigration policy and governmental speech intensify the control of the border and manifests the need to expel a large number of undocumented Mexicans. In this article, I analyze the demographic trends of the workforce under a binational and longitudinal perspective through the construction of a semi-panel. The results show convergent trends in both populations towards a gradual aging, the concentration of Mexicans in the United States at young adult ages and the return of Mexicans in all age groups to the labor market. It also shows the persistent segmentation of the U.S. labor market and the vulnerability regarding unemployment that returnees face in Mexico.

O objetivo desse artigo é testar a hipóteses de seleção positiva dos migrantes para o recorte estudado. A fonte de dados utilizada consiste nos microdados do Censo Demográfico 2010. Adota-se o modelo de regressão logística para testar a seletividade dos migrantes. Os principais resultados mostram uma razão de chance de ser migrante crescente conforme a idade, com OR de 11,45 (IC=3,62-36,24) para migrantes intermunicipais da RMV de 65 anos e mais em comparando-se com categoria de referência (15-19 anos) e que os migrantes interestaduais com destino a RMV tendem a ser do sexo feminino, mais escolarizados e auferem maiores rendimentos. Já os migrantes interestaduais, com relação ao restante da população, tendem a ser mais escolarizados e de cor/raça preta ou parda; para as variáveis idade e renda não houve associação. Assim, a migração tem se constituído um elemento importante para a região de destino com um incremento da renda nas escalas estadual e metropolitana, com a chegada de trabalhadores mais qualificados e experientes. Porém, a atração por migrantes mais envelhecidos aliada às mudanças nos comportamentos demográficos e a transição urbana representam desafios importantes, especialmente para as políticas públicas ligadas à saúde, previdência e mercado de trabalho.ABSTRACTThe objective of this article is to test the hypotheses of positive selection of the migrants for the case studied. The main data source used consists of the microdata of the Demographic Census 2010. The logistic regression model is used to test the selectivity of the migrants. The main results show an increasing odds ratio increasing as the age increases, with OR of 11.45 (CI = 3.62-36.24) for intermunicipal migrants from RMGV of 65 years and over when compared to the reference category (15-19 years) and that the interstate migrants to the RMGV tend to be female, more educated and earn higher incomes. On the other hand, the interstate migrants, with respect to the rest of the population, tend to have scholarity more elevated and to be of black or brown race/color; For the variables age and income there was no association. Thus, migration has become an important element for the destination region with an increase in income on the state and metropolitan scales, with the arrival of more skilled and experienced workers. However, the attraction of older migrants coupled with shifts in demographic behavior and urban transition present major challenges, especially for public policies relating to health, welfare and the labor market.

Este artículo se deriva de un proyecto investigativo que apunta al análisis del estado del arte sobre la gentrificación urbana en Colombia. La sistematización de investigaciones y artículos afines al desplazamiento, acompañada de un marco de referencia soportado en la gentrificación, la renta diferencial –rent gap- y el acoso –mobbing- inmobiliario, ayudaron a la reinterpretación de tales investigaciones para concluir de éstas el uso de un mecanismo para desplazar. Concretamente se puntualiza en lo sucedido en barrios del centro de Bogotá, desde la renovación urbana en Santa Bárbara (1980), calificada como inmoral, hasta las intervenciones en Santa Inés -El cartucho- (1998) y en el Voto Nacional -El Bronx- (2016), para develar la instrumentalización de ciertos seres humanos en la aplicación estrategias de acoso inmobiliario para desplazar disimuladamente, desvalorizar propiedades, especular con el suelo y de paso alentar la gentrificación. ABSTRACTThis paper is derived from a research project seeking to analyze the state of the art on urban gentrification in Colombia. A systematic literature review around displacement was carried out accompanied by a reference framework on gentrification, differential rent -rent gap– and real estate “mobbing”, which lead to a reinterpretation of such research works to conclude from these the use of a mechanism for displacement. Specifically, this study focuses on the experiences in neighborhoods in Bogota’s downtown; from the urban renewal in Santa Barbara (1980) qualified as immoral, to the interventions in Santa Inés -El Cartucho- (1998) and in Voto Nacional - El Bronx- (2016), whereupon, it was revealed a human instrumentation in the deployment of real estate “mobbing”, towards disguising displacement, devaluating properties, speculating with land and, in the meantime, encouraging gentrification.Keywords: Gentrification, rent gap, real estate mobbing

The whale sharkRhincodon typusis an endangered, highly migratory species with a wide, albeit patchy, distribution through tropical oceans. Ten aerial survey flights along the southern Mozambican coast, conducted between 2004–2008, documented a relatively high density of whale sharks along a 200 km stretch of the Inhambane Province, with a pronounced hotspot adjacent to Praia do Tofo. To examine the residency and movement of whale sharks in coastal areas around Praia do Tofo, where they may be more susceptible to gill net entanglement, we tagged 15 juveniles with SPOT5 satellite tags and tracked them for 2–88 days (mean = 27 days) as they dispersed from this area. Sharks travelled between 10 and 2,737 km (mean = 738 km) at a mean horizontal speed of 28 ± 17.1 SD km day−1. While several individuals left shelf waters and travelled across international boundaries, most sharks stayed in Mozambican coastal waters over the tracking period. We tested for whale shark habitat preferences, using sea surface temperature, chlorophyll-aconcentration and water depth as variables, by computing 100 random model tracks for each real shark based on their empirical movement characteristics. Whale sharks spent significantly more time in cooler, shallower water with higher chlorophyll-aconcentrations than model sharks, suggesting that feeding in productive coastal waters is an important driver of their movements. To investigate what this coastal habitat choice means for their conservation in Mozambique, we mapped gill nets during two dedicated aerial surveys along the Inhambane coast and counted gill nets in 1,323 boat-based surveys near Praia do Tofo. Our results show that, while whale sharks are capable of long-distance oceanic movements, they can spend a disproportionate amount of time in specific areas, such as along the southern Mozambique coast. The increasing use of drifting gill nets in this coastal hotspot for whale sharks is likely to be a threat to regional populations of this iconic species.

Published: January 2018

AbstractSilk/polyethylene glycol (PEG) hydrogels are studied as self‐standing bioinks for 3D printing for tissue engineering. The two components of the bioink, silk fibroin protein (silk) and PEG, are both Food and Drug Administration approved materials in drug and medical device products. Mixing PEG with silk induces silk β‐sheet structure formation and thus gelation and water insolubility due to physical crosslinking. A variety of constructs with high resolution, high shape fidelity, and homogeneous gel matrices are printed. When human bone marrow mesenchymal stem cells are premixed with the silk solution prior to printing and the constructs are cultured in this medium, the cell‐loaded constructs maintain their shape over at least 12 weeks. Interestingly, the cells grow faster in the higher silk concentration (10%, w/v) gel than in lower ones (7.5 and 5%, w/v), likely due to the difference in material stiffness and the amount of residual PEG remaining in the gel related to material hydrophobicity. Subcutaneous implantation of 7.5% (w/v) bioink gels with and without printed fibroblast cells in mice reveals that the cells survive and proliferate in the gel matrix for at least 6 week postimplantation. The results suggest that these silk/PEG bioink gels may provide suitable scaffold environments for cell printing and function.
Bioinspired Interfacial Materials: From Binary Cooperative Complementary Interfaces to Superwettability Systems

Published: January 2018

AbstractIn this review, the binary cooperative complementary principle, which applies to two complementary states, has been proposed as a powerful law for construction of novel functional interfacial materials. The idea is to tune the distance between these two complementary components to match the characteristic length of certain physical interactions so that the cooperation between these complementary building blocks becomes dominant and thus endows the interfacial materials with unique properties. Since 2000, the binary cooperative complementarity for design of bioinspired superwettability systems has been applied by regulating the structural roughness to ≈100 nm to match the characteristic length of the hydrophobic interaction. It has been proved that the binary cooperative complementary law gains great success in constructing bioinspired superwettability systems. It is believed that much more novel interfacial materials with unique multifunctions will be generated following the binary cooperative complementary principle.

AbstractPlasmonic gratings of rectangular groove profile with gradient in the groove width perform as unique surface‐enhanced Raman spectroscopy (SERS) substrates by simultaneously confining multiple laser wavelengths proximally and inside their rectangular nanotrenches. These gratings consist of a metal–insulator–metal (MIM) groove of 40 nm width at the center, surrounded by grooves with widths increasing in 10 nm steps to a maximum of 180 nm. It is experimentally shown and theoretically confirmed that upon illumination a maximally enhanced electromagnetic field is generated at the center of these gratings as a result of plasmonic light trapping as well as waveguiding produced by the surrounding grooves. SERS enhancement factors of 106–107 are demonstrated for 20 μL min−1 flow of 1 × 10−3m aqueous phospholipid solution using 532, 638, and 785 nm laser illumination of the gratings integrated within microfluidic devices. These robust multiwavelength SERS substrates offer highly reproducible plasmonic field enhancement that can be tuned to cover broad wavelength ranges within the visible and near‐infrared regime and are ideal for static and dynamic characterization of low concentration species. Further, the multispectral characteristic of these gratings facilitates multiplexing through various laser wavelengths thereby making it possible to readily access weak or silent Raman modes.
