Full textFor several decades, the military has used the Multiple Integrated Laser Engagement System (MILES) with a series of iR sensors along a belt fastened to a vehicle for training and simulation. Now, an alternative to this legacy system, a solar rechargeable battery powered wireless IR sensor is replacing wired sensors. The use of short-range RF communications network, allows the MILES sensors strategic placement about a combat vehicle without the umbilical cabling normally required for power and signal coupling from the players processing unit. The RF network operates in the 340 to 380 MHz band, has channeling capability of over 1600 channels, and coexists with the vehicles on board high-powered radios without interference. The wireless sensor implements a custom designed IR sensing amplifier, designed for maximum sensitivity and minimal power dissipation, along with advanced semiconductor IC’s for signal processing and power conversion. Solar recharging enables the sensor to operate for extended time, on a single battery that should last for years without replacement. A proprietary software protocol, developed for communication integrity, is a critical part of the overall system and supports other sensor types and control elements with low data rates for a wireless Vehicle Area Network. The system, successfully installed on several military training platforms, proves to be a viable product for military training and simulation systems for the 21st century.

Full textLas actuales aportaciones tecnocientíficas enfocadas al confort, especialmente dirigidas a complementar los espacios arquitectónicos, abren una importante gama de posibilidades al Diseño, profundizando en el conocimiento del ser humano y postulando las características naturales que requiere en su entorno inmediato. Respecto a las aportaciones en el tema, el enfoque se encuentra principalmente en la construcción de una red heterogénea de investigación en iluminación circadiana domotizada© que facilite al investigador, la construcción de los estudios aquí señalados, para mejorar la sincronización del ritmo circadiano en los habitantes principalmente asociados a una vida de ciudad, con sus particulares actores geográficos, urbano-administrativos y ambientales que, a su vez, permita fomentar una vida con mayor confort y salud. En esta investigación, se analizaron una serie de aspectos asociados, de entre los que destacan, la iluminación natural que procede del sol, la iluminación en un espacio construido y las formas de intervención lumínicas artificializadas. Numerosas investigaciones han estudiado la respuesta que tienen los organismos biológicos a esta iluminación natural, así como algunas complicaciones con el uso permanente de iluminación artificial; debido a las actividades sociales, económicas, tecnológicas y laborales, particularmente en las poblaciones urbanas; observando y analizando la forma en que se generan los desajustes en el flujo natural de la neurobiología humana. En paralelo, se diseñó un sensor fototrópico© domotizado que permitió caracterizar la marcha lumínica diaria en sus principales componentes luminosos; posteriormente se diseñó un dispositivo de iluminación circadiana y se puso en experimentación en situación directa con una actividad humana. El presente trabajo muestra dos tipos de diseño, 1. La construcción de la red heterogénea de investigación en iluminación circadiana domotizada©; que, en un principio, se desarrolló a partir del análisis y comprensión de la literatura existente en iluminación, circadianismo y domótica, así como de la observación y práctica en algunos laboratorios especializados en iluminación. Esto, dio paso a la construcción de las dimensiones que componen la red y a cada uno de sus aspectos y elementos. 2. A partir del diseño anterior, se implementó la puesta en marcha de la red heterogénea de investigación, la cual se formuló en diferentes etapas investigativas que comprende desde el diseño e implementación de instrumental especializado, la caracterización lumínica natural, el desarrollo de un dispositivo de iluminación circadiana©, basado en la marcha lumínica diaria©, hasta la instalación y puesta en marcha en un espacio de actividades escolares como estudio de caso, para documentar su respuesta de confort. Durante el estudio de la literatura existente, se encontró que el entorno habitable juega un importante factor de influencia para la implementación de diferentes sincronizadores que estimulan al ritmo circadiano humano. Haciendo uso de la red heterogénea de investigación propuesta en el presente trabajo, se comprobó la obtención y réplica de los valores aproximados para la intervención y emulación lumínica artificial en un espacio arquitectónico, generando propuestas de diseño para espacios integrales, inteligentes, saludables y confortables. Derivado del diseño de la red heterogénea de investigación en iluminación circadiana domotizada©, se generó otra declinación del diseño investigativo, mismo que pasó por aspectos específicos de diseño de: 1. pesquisas sobre la observación del fenómeno natural de la iluminación, mediante el diseño de instrumental avanzado para su observación analítica denominado sensor fototrópico©,toma de datos de la exposición luminosa diaria real en un punto geográfico, procesamiento y caracterización de la marcha lumínica diaria© (MLD). Estos aspectos fueron desarrollados en la perspectiva de fundamentar las siguientes dos dimensiones. 2. Pesquisas sobre la influencia que existe entre los cambios de la MLD y la sincronización del ritmo circadiano en el ser humano; considerando a la iluminación natural, como el principal medio de sincronización del reloj biológico y, por lo tanto, el soporte fundamental para diseñar dispositivos de iluminación emuladores de la MLD. Estos aspectos fueron tratados de manera relacional con las otras dos dimensiones de la red: por un lado, tomando la utilidad de los resultados de la MLD a la luz de las investigaciones neurobiológicas circadianas y; por otro lado, fundamentar la idea circadiana del vínculo entre MLD y su emulación artificial. 3. Pesquisas sobre la emulación de la MLD en un espacio construido mediante el diseño de una luminaria capaz de replicar sus principales factores mediante el diseño, integración y aplicación de software y hardware, capaz de emitir instrucciones para la emulación de la MLD en el dispositivo de iluminación adaptable a los espacios arquitectónicos convencionales. Estos aspectos fueron desarrollados a partir de los resultados de las primeras dos dimensiones, mismos que se integraron en la propuesta de investigaciones de dispositivos de iluminación circadiana domótica©. Finalmente. Las dimensiones anteriores se integraron en una propuesta de un dispositivo de iluminación circadiana domotizada© (ICD) en un espacio escolar como estudio de caso, para investigar cambios en el desempeño de la reproducción colorimétrica del medio circundante, de escolares de educación básica en México; en el entendido que un buen desempeño escolar, sería un símbolo de confort lumínico. Además de lo anterior, en esta propuesta de dispositivo de ICD, se pone en juego las tres dimensiones heterogéneas y muestran la escala mínima de una red de investigación de ICD. El dispositivo, pone en relación y retroalimenta cada una de las tres dimensiones, en el sentido que, respecto a la primera fijaría la MLD en un punto geográfico exacto; a la segunda, precisaría los mejores lapsos horarios de cierta actividad humana y; a la tercera, mejoraría la integración de la propuesta de iluminación emulada. El enfoque epistemológico de esta investigación es la teoría actor-red. Es una episteme que permite reunir sintéticamente los elementos que interactúan en escenarios asociados indisolublemente. Con este enfoque se diseñó la red heterogénea de investigación en iluminación circadiana domotizada y se puso en marcha mediante instrumentos técnicos para la emulación artificializada del fenómeno lumínico natural para la sincronización del ritmo circadiano, en función de las actividades humanas. Se trata, parafraseando a Arellano, de un enfoque metodológico y de diseño hacia el confort, que proporciona elementos para investigar y desarrollar la elaboración de asociaciones heterogéneas de naturalezas, de artefactos y de colectivos humanos.

Financial inclusion has gained recognition as both a domestic and international governance objective. However, full participation in the financial sector remains an elusive goal, and a number of significant questions present themselves regarding defining the scope of financial inclusion and formulating efficacious policy to ensure access to and promoting the usage of financial services. Paramount among these questions is the relationship between the geographic aspects of retail financial markets and consumer outcomes including rates of savings and indebtedness, the types of consumer credit utilized, and levels of unbanked and underbanked populations. The central aim of this research is to address this lack of understanding by using quantitative analytical tools including geographic information systems (GIS) and spatial regression analysis to examine relationships between the uneven geography of retail financial services, mortgage lending activity, and sociodemographic variables. Four metropolitan study areas in the United States—Las Vegas, Nevada; Los Angeles, California; Miami, Florida; and Philadelphia, Pennsylvania—are examined in order to address a range of question related to the neighborhood level determinants of financial inclusion. This study will provide a foundation for improving policy solutions through contributing to the understanding of how data-driven and analytical approaches can be applied to this problem. Specifically, the following research questions are addressed: 1) How does the spatial distribution of mainstream financial institutions (banks and credit unions) and alternative financial service providers (AFSPs) contribute to financial inclusion at the neighborhood level? What is the geographic relationship between these services; and how does access to these services interact with neighborhood demographic variables and mortgage lending activity? 2) How can traditional approaches to spatial analysis of mortgage lending be improved and expanded to incorporate new spatial analysis methods and better understand how mortgage credit denial and subprime lending interact with one another, as well as with neighborhood demographic variables? Building on scholarship in the academic areas of community reinvestment, asset building, and economic geography, this research contributes a number of new insights and refinements in methodology. The results of spatial regression analyses reveal significant predictive relationships, even after controlling for sociodemographic variables and spatial clustering by using simultaneous autoregressive (SAR) models. This research is unique in its examination of the relationship between the landscape of financial services in neighborhoods and mortgage lending activity, and finds that increasing levels of subprime mortgage lending in neighborhoods is predictive of nearer distance to AFSPs. Another finding is that higher percentages of black and Latino populations in neighborhoods are predictive of nearer proximity to AFSPs and greater distances to mainstream brick-and-mortar financial institution locations. A new method is developed to address the spatial void hypothesis, the spatial relationship between mainstream financial institutions and AFSPs. The results of binary logistic regression models indicate that neighborhoods where alternative service providers are more prevalent comparatively feature lower average income levels, higher percentages of minority residents, lower levels of educational attainment, and higher levels of both mortgage application denial and subprime mortgage lending. Advances are also made in developing regression models to address relationships between sociodemographic variables and mortgage lending activity. Using SAR modeling, this study finds that mortgage purchase denial is a strong predictor of subprime lending for home purchase and refinance loans. Confirming prior research findings with a new method, the percentage of the population that is black and Latino is found to be a statistically significant predictor of mortgage purchase denial, as well as rates of subprime mortgage purchase lending.

O uso inadequado do ambiente provoca uma quebra na din?mica natural do ecossistema, prejudicando-o de forma geral todos os elementos que o comp?e. Os espa?os naturais v?m sendo alvo de diversas atividades antr?picas, o que ocasiona uma s?rie de impactos ambientais. Dentre eles pode-se citar os dep?sitos de res?duos s?lidos a c?u aberto, passivos ambientais que necessitam de planos de recupera??o. A presen?a de banco de semente, pl?ntulas, brota??es e vegeta??o potencializam os processos de recupera??o, entretanto, a presen?a de esp?cies ex?ticas com car?ter invasor minimizam o processo devido a sua alta competitividade quando comparadas a esp?cies nativas, sobrevivendo e reproduzindo nas mais diversas condi??es de estresses ambientais. Neste sentido, foi escolhida como ?rea de estudo, o dep?sito de res?duos s?lidos de Diamantina, desativado em 2002, situado no Campus Juscelino Kubitscheck, da Universidade Federal dos Vales do Jequitinhonha e Mucuri, regi?o do Alto Jequitinhonha, Minas Gerais. O presente estudo teve como objetivo avaliar o melhor controle de gram?neas invasoras dos g?neros Melinis e Urochloa por meio de diferentes m?todos: manual, mec?nica, qu?mica e qu?mica + mec?nica, assim como a aplica??o de um m?todo n?o destrutivo, por meio de uso de imagens digitais analisadas pelo software ImageJ para an?lise do comportamento de tais esp?cies na ?rea degradada. Metodologicamente, conduziu-se o experimento por delineamento em blocos casualizados em 4 blocos, subdivididos em 16 parcelas com 4 tratamentos em cada e 4 repeti??es por bloco. A coleta da biomassa de gram?neas regenerantes frescas ocorreu ap?s 100 dias dos m?todos com aux?lio de uma moldura de ferro, com dimens?es de 1,0 x 1,0 m, em tr?s locais predefinidos em cada parcela, totalizando tr?s amostras coletadas por parcela e quarenta e oito amostras por bloco. As imagens utilizadas para an?lise e processamento no software ImageJ foram obtidas com a mesma moldura localizada nos locais predefinidos em cada parcela para os 4 blocos experimentais ap?s 100 dias dos diferentes tipos de m?todos. Os dados processados resultaram em uma varia??o entre os diferentes tipos de m?todos empregados. Obteve-se um menor controle na produ??o de biomassa fresca quando se utilizou controle mec?nico, seguido pela combina??o do m?todo mec?nico + qu?mico. Os m?todos qu?mico e manual apresentaram menores valores de produ??o de biomassa fresca enquanto a produ??o de mat?ria seca n?o apresentou diferen?a significativa estatisticamente. Os dados processados pelo software resultaram em n?tida varia??o entre os m?todos utilizados, com menor porcentagem de cobertura do substrato pelas esp?cies invasoras quando se utilizou controle qu?mico, seguido pelo m?todo manual. O m?todo mec?nico e tratamento qu?mico + mec?nico apresentaram os maiores percentuais de cobertura das esp?cies invasoras estatisticamente.

The environment for the inappropriate use causes a break in the natural dynamics of the ecosystem, damaging it in general all the elements that compose it. Natural spaces come target of various human activities, which causes a number of environmental impacts. Among them we can mention the deposits of solid waste in the open, environmental liabilities that require recovery plans. The presence of seed bank, seedlings, shoots and vegetation in enhancing the recovery process, however, the presence of exotic species with invasive character minimize the process due to its high competitiveness when compared to native species, surviving and reproducing in various conditions environmental stresses. In this sense, it was chosen as the study area, the solid waste open dumping site of Diamantina town, disabled in 2002, located in the Campus Juscelino Kubitschek of the Federal University of Jequitinhonha and Mucuri Valleys, Upper Jequitinhonha Valley, Minas Gerais. This study aimed to evaluate the best control invasive grasses the Melinis and Urochloa genres through different methods: manual, mechanical, chemical and chemical + mechanical, as well as the application of a non-destructive method, through use of images digital analyzed by ImageJ software for analysis of such kinds of behavior in the degraded area. Methodologically, the experiment was conducted by a randomized block design in 4 blocks, divided into 16 plots with 4 treatments each and 4 replicates per block. The gathered of fresh biomass regenerating grasses occurred after 100 days of weeding with the help of a 1.0 x 1.0 m iron frame in three pre-defined locations in each plot, with three samples per plot and forty and eight samples per block. The images used for analysis in ImageJ software and processing were obtained with the same frame located at the predefined locations in each plot for experimental 4 block after 100 days the different methods. The processed data resulting in a variation between the different types of methods employed. It was obtained less control in the production of fresh biomass when using mechanical control, followed by combining the mechanical + chemical method was obtained. Chemical and manual methods had lower fresh biomass production values while the production of dry matter did not show statistically significant difference. The data processed by the software resulted in a sharp variation in the methods used, with a lower percentage of substrate coverage by invasive species when using chemical control, followed by the manual method. The mechanical method and chemical + mechanical treatment showed the highest percentage of coverage of invasive species statistically.

Full textAbstract. Parrotfish, a herbivorous reef fish, is considered to play an important role within coral reef ecosystems, enhancing coral reef resilience by keeping algal growth in check, allowing slower-growing coral recruits to settle. The functional performance of parrotfish species has been indicated to be dependent on body size. Albeit increasing size selective fishing pressure maintains, leading to immense effects on the dynamics of coral reefs, with consequences often much larger than changes in biomass and abundance of the targeted stock itself. The relative importance of the relationship between function (grazing) and body-size was tested in two parrotfish species (Scarus niger and Chlorurus sordidus) in the Red Sea. A non-linear relationship was found between functional performance and body size, with function found to increase notably as fishes reach a size of 15-20 cm At a regional level, parrotfish function was found to be low. These findings support the idea of a generalized ecological pattern of functional performance in parrotfishes. Demographic skewness within parrotfish species populations could easily be incorporated in routine monitoring schemes, thus act as a comparatively cheap and easily monitored indicator for assessing coral reef resilience, especially useful for managers in areas of limited budgets. Other alternative stable states than macroalgae, are speculated to be the case in the Red Sea.

Full textIn this report, we evaluate the role of visual areas responsive to motion in the human brain in the perception of stimulus speed. We first identified and localized V1, V3A, and V5/MT+ in individual participants on the basis of blood oxygenation level-dependent responses obtained in retinotopic mapping experiments and responses to moving gratings. Repetitive transcranial magnetic stimulation (rTMS) was then used to disrupt the normal functioning of the previously localized visual areas in each participant. During the rTMS application, participants were required to perform delayed discrimination of the speed of drifting or spatial frequency of static gratings. The application of rTMS to areas V5/MT and V3A induced a subjective slowing of visual stimuli and ( often) caused increases in speed discrimination thresholds. Deficits in spatial frequency discrimination were not observed for applications of rTMS to V3A or V5/MT+. The induced deficits in speed perception were also specific to the cortical site of TMS delivery. The application of TMS to regions of the cortex adjacent to V5/MT and V3A, as well as to area V1, produced no deficits in speed perception. These results suggest that, in addition to area V5/MT+, V3A plays an important role in a cortical network that underpins the perception of stimulus speed in the human brain.

O presente trabalho tem como objetivo analisar os diversos perfis de atuação dos grupos sociais que compuseram a elite do termo de Pitangui entre os anos de 1715 a 1760, atentando para suas diferentes relações com a Coroa. Essa temática envolve a questão da conformação e legitimação dos espaços de poder na localidade e as estratégias utilizadas pelos atores, no sentido de alcançarem os mais altos patamares da hierarquia social. Sendo assim, buscamos compreender como o processo de conquista e povoamento da região esteve relacionado com a atuação de um grupo de paulistas que contestava frequentemente as regras estabelecidas pelas autoridades metropolitanas, para fazer valer seus interesses particulares. Esses indivíduos não só se rebelaram, em alguns momentos, contra os desígnios da Coroa, como buscavam submeter e/ou cooptar os demais grupos sociais que se estabeleciam na localidade, baseando-se em suas prerrogativas de primeiros conquistadores. Tal postura de insubmissão explica a imagem tradicionalmente relacionada aos habitantes da Vila de Pitangui e de seu termo pelas autoridades régias, durante a primeira metade do século XVIII, forjada a partir de um contexto marcado por diversos conflitos e motins ocorridos, nas duas primeiras décadas dos setecentos. Por outro lado, buscamos confrontar a imagem do rebelde com o perfil de outro grupo, em que seus integrantes se comportavam enquanto fieis vassalos, ou seja, daqueles cuja relação com a Coroa e suas autoridades locais se baseava, em grande medida, na prestação de serviços à monarquia e na consequente retribuição dos mesmos por parte do monarca, o que garantia a essas pessoas uma série de benefícios e privilégios, contribuindo muito para que elas ocupassem lugares de destaque na pirâmide social. A partir dessa análise, surgiram também trajetórias de indivíduos que não contestavam o poder da Coroa da região, mas que, pelo menos aparentemente, não participaram do governo da municipalidade, perfil de atuação alternativo na constituição da identidade da elite colonial na América Portuguesa.
This work has the objective of analyzing the different performance of the social groups that composed the elite of the Termo de Pitangui between the years 1715 to 1760, paying attention to their different relations with the Crown. This theme involves the question of the conformation and legitimation of the power spaces in the locality and the strategies used by the actors, seeking to reach the highest levels of the social hierarchy. Thus, we sought to understand how the process of conquest and settlement in the region was related to the performance of Paulistas who frequently challenged the rules established by the metropolitan authorities to assert their particular interests. These individuals not only rebelled at times against the designs of the Crown, as they sought to subject and/or co-opt the other social groups that established themselves in the locality, basing themselves on their prerogatives as first conquerors. This position of insubordination explains the image traditionally related to the inhabitants of the Pitangui by the metropolitan authorities, during the first half of the eighteenth century, forged from a context marked by several conflicts and riots that occurred in the first two decades of seven hundred. On the other hand, we sought to confront the image of the rebel with the profile of another group in which its members behaved like faithful vassals, that is, those whose relationship with the Crown and its local authorities was based to a large extent on the provision of services to the monarchy and the consequent retribution of the same by the monarch, which guaranteed to these people a series of benefits and privileges, contributing much so that they occupied prominent places in the social pyramid. From this analysis, we also found trajectories from individuals who did not contest the power of the Crown of the region but who, at least apparently, did not participate in the municipal government, an alternative profile in the constitution of the colonial elite identity in Portuguese America.

This study aimed to characterize, for the first time, the benthic invertebrates that inhabit the region of soft bottoms adjacent to the APARC reefs in order to situate them as an important component of infralittoral coastal areas of Northeast Brazil. Soft bottoms areas of APARC corresponds to infralittoral zones vegetated by seagrass Halodule wrightii and unvegetated infralittoral zones, both subjected to substantial hydrodynamic stress. Through scuba diving, biological and sedimentary samples of both habitats were analyzed, with a cylindrical sampler. We identified 6160 individuals belonging to 16 groups and 224 species. The most abundant macrofaunal group was Polychaeta (43%), followed by Mollusca (25%) and Crustacea (14%), what was expected for these environments. In the first chapter, regarding vegetated areas, we tested three hypotheses: the existence of differences in the faunal structure associated with H. wrightii banks submitted to different hydrodynamic conditions; the occurrence of minor temporal variations on the associated macrofauna of banks protected from hydrodynamic stress; and if the diversity of macrofauna is affected by both benthophagous predators and H. wrightii biomass. It was observed that macrofauna associated at the Exposed bank showed differences in structure when comparing the Protected bank, the granulometry of the sediments, that co-varies with the hydrodynamism, was the cause of these variations. The results also pointed to a lower temporal variation in the macrofaunal structure on the Protected bank and a negative relation between macrofaunal and benthophagous fish abundance. At the Exposed bank, a greater faunal diversity was observed, probably due to the higher seagrass biomass. The second chapter compares the vegetated and non-vegetated areas in order to test the hypothesis that due to greater seasonal stability in tropical environments, seagrass structure would act to distinguish the vegetated and non-vegetated areas macrofauna, over time. It was also expected that depositivores were the most representative invertebrates on non-vegetated environments, on the assumption that the seagrass bank would work as a source of debris to adjacent areas, enriching them. Considering all sampling periods, the total macrofauna abundance and diversity were higher in vegetated areas, when compared to non-vegetated ones. Seasonally, the structural complexity provided by Halodule differentiated more clearly the fauna from vegetated and non-vegetated areas, but only at the climatic extremes, i.e. Dry season (extreme climatic stability, with low hydronamism variation) and Rainy season (great hydrodynamism variation and probably vegetated bank burial). Furthermore, the high organic matter levels measured in the sandy banks coincided with an outstanding trophic importance of deposit feeders, proving the debris-carrying hypothesis. The last chapter focused on the non-vegetated areas, where we tested that the hypothesis infaunal halo in tropical reefs depending on local granulometry. In this context, we also tested the hypothesis that benthophagous fish predation would have an effect on the low abundance of macrofaunal groups due to the high hydrographic stress, thus allowing other predatory groups to have greater importance in these environments. Proving the hypothesis, no spatial variation, both on abundance families neither on community structure, occur along distance of the edge reefs. However, we found that complex combinations of physical factors (grain size and organic matter levels originated from local hydronamic conditions) covary with the distance from the reefs and has stronger influence on macrofauna than considered biological factors, such as predation by benthophagous fishes. Based on the main results, this study shows that unconsolidated areas around APARC reefs are noteworthy from an ecological and conservational point of view, as evidenced by the biota-environment and organismal relations, never before described for these areas
Objetivou-se caracterizar, pela primeira vez, os invertebrados bent?nicos que habitam a regi?o de fundos moles adjacentes aos recifes da ?rea de Prote??o Ambiental dos Recifes de Corais (APARC), a fim de situ?-los como importante componente das zonas infralitorais costeiras do Nordeste do Brasil. As ?reas de fundos moles, ou n?o consolidadas, da APARC compreendem regi?es de infralitoral, vegetadas pela angiosperma marinha Halodule wrightii, e regi?es de infralitoral n?o vegetadas, ambas submetidas a um considerado estresse hidrodin?mico. Atrav?s de mergulho aut?nomo, foram analisadas amostras biol?gicas e sedimentares de ambos os habitats, com aux?lio de amostrador cil?ndrico de PVC. Foram identificados 6160 indiv?duos, distribu?dos em 16 grandes grupos e 224 esp?cies, sendo que o grupo macrofaunal mais abundante foi Polychaeta (43%), seguido de Mollusca (25%) e Crustacea (14%), resultado j? esperado para ambientes n?o consolidados infralitorais. No primeiro cap?tulo, relacionado ?s ?reas vegetadas, foram testadas tr?s hip?teses: a exist?ncia de diferen?as na estrutura??o da fauna associada a bancos de H. wrightii, submetidos a diferentes condi??es hidrodin?micas; a ocorr?ncia de menores varia??es temporais sobre a macrofauna associada aos ambientes mais protegidos do estresse hidrodin?mico; e se a diversidade da macrofauna ? afetada, tanto pelos predadores bent?fagos como pela biomassa da pr?pria H. wrightii. Foi verificado que a macrofauna associada do banco Exposto apresentou diferen?as na estrutura??o quando comparado ao banco Protegido, sendo a granulometria dos bancos, a qual varia conjuntamente com o hidrodinamismo, a respons?vel por estas varia??es. Os resultados tamb?m apontaram para uma menor varia??o temporal na estrutura da macrofauna no banco Protegido e uma rela??o negativa entre a abund?ncia macrofaunal e peixes bent?fagos. J? no banco Exposto, foi encontrada uma maior diversidade faunal, provavelmente em fun??o da maior biomassa de gram?nea. O segundo cap?tulo aborda uma compara??o entre ?reas vegetadas e n?o vegetadas, pretendendo testar a hip?tese de que, em fun??o de uma maior estabilidade sazonal nos ambientes tropicais, a estrutura da faner?gama atuaria na distin??o da macrofauna associada entre ?reas vegetadas e n?o vegetadas, ao longo do tempo. Tamb?m se esperava que os deposit?voros fossem os invertebrados mais representativos nos ambientes n?o vegetados, partindo da premissa de que o banco de faner?gama funcionaria como fonte de detritos para ?reas adjacentes, enriquecendo-as. Todavia, sazonalmente, a complexidade estrutural proporcionada por Halodule discriminou, com mais evid?ncia, a fauna de ?reas vegetadas de n?o vegetadas somente nas extremidades clim?ticas, isto ?, no per?odo Seco (extrema estabilidade clim?tica, com pouca varia??o no hidrodinamismo) e no per?odo Chuvoso (grande varia??o do hidrodinamismo e prov?vel soterramento do banco vegetado). Al?m disso, os elevados teores de mat?ria org?nica medidos nos bancos arenosos coincidiram com uma destacada import?ncia tr?fica dos deposit?voros, comprovando a hip?tese de carreamento de detritos. O ?ltimo cap?tulo focou nas ?reas n?o vegetadas, em que se testou a hip?tese de que a varia??o da estrutura da macrofauna perto e longe ocorre em decorr?ncia da granulometria. Neste contexto tamb?m foram testadas a hip?tese de que a preda??o por peixes bent?fagos teria um baixo efeito na abund?ncia dos grupos da macrofauna em fun??o do alto estresse hidrogr?fico, abrindo, assim, espa?o para outros grupos de predadores bent?fagos terem uma maior import?ncia nestes ambientes. Comprovando as hip?teses levantadas, n?o foi verif icada varia??o espacial significativa entre as dist?ncias da borda dos recifes, tanto na abund?ncia das principais fam?lias identificadas como na estrutura geral das comunidades bent?nicas. Entretanto, verificou-se que uma complexa combina??o de fatores f?sicos (tamanho do gr?o e teor de mat?ria org?nica derivadas das condi??es hidrodin?micas locais) variam conjuntamente com a dist?ncia e influencia mais a macrofauna do que os fatores biol?gicos considerados, como a preda??o por peixes bent?fagos. Com base nos principais resultados encontrados, este trabalho mostrou que as ?reas de fundos n?o consolidados do entorno dos recifes da APARC merecem destaque do ponto de vista ecol?gico e de conserva??o, pois evidenciou-se importantes rela??es da biota com o ambiente e da biota com outros organismos n?o descritas antes para estas ?reas

This study examined the differences in teacher racial ideology among white teachers in urban, suburban, and rural areas. This study advances the scholarship on the ideological frames used by teachers in urban, suburban, and rural areas through an examination of the differences in teachers’ discourse and racial ideology. Using contact theory, this study employed interviews to examine teachers’ discourse related to racial inequality in education to determine whether there were similarities in teacher discourse within and across urban, suburban, and rural areas with differing racial compositions. Interviews were conducted with 42 teachers in urban, suburban, and rural school districts during the 2014-2015 school year. There were three major findings in this study. First, four original frames of color-conscious racial ideology were present in data across urban, suburban, and rural areas. Second, teachers across all areas employ the systemic responsibility frame to talk about the achievement gap, and the cultural racism frame to talk about increased violence in urban areas, revealing that teachers frame some topics similarly across areas of differing racial composition. Third, analysis of teacher racial ideologies using the eight frames of color-conscious and color-blind racial ideology reveal that teachers within Lincoln City, Gresham, and Arcadia employ specific frames within each area to talk about racial inequality in education. Further, teachers in Lincoln City and Gresham framed racial inequality in education more consistently using color-conscious frames than teachers in Arcadia, indicating that contact with outgroup members also shapes teacher racial ideology.

Full textStudies on Brazilian biodiversity are still very few and can observe the difference of knowledge between the different regions of the country. This affirmation can be verified in the investigation to identify the rare species in Brazil and the key biodiversity areas (ACBs). In that study were identified for Brasil 2.256 rare species and 752 ACBs. The Rio Grande do Norte (RN) was the only Brazilian state that has not been identified any rare species and no ACBs, possibly due to the lack of floristic studies in this state. A particular area was selected for this study: an area of ecological tension with savanna physiognomy in Rio do Fogo, RN. This savanna community is represented in RN in a fragment and immersed in restinga and caatinga and was identified and described only through of radar imagens there are no studies to date in loco . We have prepared the following questions about this community savanna: 1) The region delimited and described by through of radar images by the RADAMBRASIL, 1976, can be associated of the Cerrado, in terms of floristic ?; 2) What is the floristic composition of this area? This area includes rare species, endemic or endangered? 3) What is the geographical and phytogeographical distribution of plant species registered in this area? 4) Those plant species registered are endemic or have affinity with other areas phytoecological Brazilian? To answer these questions we performed a floristic inventory of the August 2007 to September/2009. The results are presented in two chapters (manuscripts). The first chapter, titled "The Savannah Rio Grande do Norte: floristic links with other plant formations in the Northeast and Center-West Brazil" was submitted to the Revista Brasileira de Bot?ncia. Chapter 1 discusses the phytogeographical distribution of the species, by comparing floristic studies conducted in the Cerrado, Caatinga and Restinga in the Northeast and Cerrado of the Central Brazil. The analysis of data of this study and compilation with other studies indicated that: i) the record of 94 plant species; ii) of total species, about 64% are associated with the Cerrado, the second specialized bibliography, and about 78% as the List of Species of Flora of Brazil. However, about 73% of total species (94) are also distributed in the Caatinga, the Atlantic forest 64%, the Amazon forest 64%, the Pantanal 15% and the Pampa 12%. Floristically the data show that the community studied is influenced by other floras, has a structure where grasses dominate and also because of his appearance the same savanna then be classified as a Savana gram?neo-lenhosa do tabuleiro . Chapter 2, titled "Considerations on the flora of a savanna community in Rio Grande do Norte, northeastern Brazil: Subsidy key area for conservation" was submitted to the Revista Natureza e Conserva??o. This has the objective of improve the knowledge of flora of Rio Grande do Norte and to identify possible rare species and consequently increase the key areas of biodiversity in Brazil. The data indicated that: i) of 94 species registered in the study area, 40 were new records for the Rio Grande do Norte state; ii) These citations to unpublished state, Stylosanthes montevidensis Vogel (Fabaceae) and Aristida laevis (Nees) Kunth (Poaceae) are indicated for the first time to the Northeast of Brazil; iii) are registered in the area 24 species endemic to Brazil and 63 non-endemic; iv) Aspilia procumbens Baker (Asteraceae) registered in the area is considered a restricted species and micro endemic Rio Grande do Norte, ie rare species; v) Aspilia procumbens is also cited in the category of critically endangered species and Stilpnopappus cearensis Hubber (Asteraceae) a species vulnerable to extinction. This study shows a new area phytoecological in Rio Grande do Norte and indicates the area's potential to contribute with the sites of global significance for biodiversity conservation, either locally, regionally and nationally. This will certainly contribute to respond some targets set by the Global Strategy for Plant Conservation and the Convention on Biological Diversity such as the inventory of vegetal diversity in a region with little collection, which will provide data that contributes to questions and themes related to biodiversity.
Estudos sobre a biodiversidade brasileira s?o ainda muito escassos, sendo poss?vel observar uma grande discrep?ncia de conhecimentos entre as v?rias regi?es do pa?s. Esta afirma??o est? baseada no fato de que foram identificadas para o Brasil 2.256 esp?cies raras de plantas e 752 ?reas-chave para biodiversidade (ACBs), no entanto, o Rio Grande do Norte foi o ?nico estado brasileiro que n?o apresentou nenhuma esp?cie rara e nenhuma ?rea-chave para biodiversidade, possivelmente, devido ? escassez de levantamentos flor?sticos nesse estado. O presente estudo foi realizado em um ambiente especial: uma ?rea de tens?o ecol?gica com fisionomia sav?nica localizada no munic?pio de Rio do Fogo, RN. Essa comunidade sav?nica est? representada na forma de pequena mancha e imersa entre a Caatinga e a Restinga. Foi identificado e descrito apenas com base em imagens de radar, n?o havendo, at? o presente momento, estudos in loco. Neste contexto foram elaboradas algumas perguntas sobre essa comunidade sav?nica: 1) A regi?o delimitada e descrita por meio de imagens de radar, RADAMBRASIL de 1976, pode ser do dom?nio Cerrado, do ponto de vista flor?stico?; 2) Qual ? a composi??o flor?stica dessa ?rea? Ela inclui esp?cie rara, end?mica ou amea?ada de extin??o?; 3) Qual ? a distribui??o geogr?fica e fitogeogr?fica das esp?cies vegetais registradas nessa ?rea?; 4) As esp?cies vegetais registradas s?o end?micas ou possuem afinidade com outros dom?nios fitoecol?gicos brasileiro? Visando responder a essas indaga??es foi realizado um levantamento flor?stico, no per?odo de agosto/2007 a setembro/2009. Os resultados obtidos s?o apresentados em forma de dois cap?tulos (manuscritos). O cap?tulo 1, intitulado A Savana do Rio Grande do Norte: Rela??es flor?sticas com outras forma??es vegetais do Nordeste e Centro-Oeste Brasileiro foi submetido ? Revista Brasileira de Bot?nica. Aborda a distribui??o fitogeogr?fica das esp?cies, atrav?s da compara??o com estudos flor?sticos realizados nos cerrados, caatingas e restingas do Nordeste e cerrados do Planalto Central. As an?lises dos dados obtidos no presente trabalho e, tamb?m, atrav?s de compila??o com outros estudos apresentaram: i) o registro de 94 esp?cies vegetais; ii) desse total de esp?cies, cerca de 64 % est?o associadas ao Cerrado, segundo bibliografia especializada, e cerca de 78 % conforme a Lista de Esp?cies da Flora do Brasil. Todavia, cerca de 73 % do total das esp?cies (94) registradas tamb?m se distribuem na Caatinga, 64 % na Floresta Atl?ntica, 50 % na Floresta Amaz?nica, 15 % no Pantanal e 12 % no Pampa. Floristicamente os dados apontaram que comunidade estudada recebe influ?ncia de outras floras, possui uma estrutura onde as gram?neas dominam e tamb?m devido a sua fisionomia sav?nica a mesma, ent?o, poder ser classificada como Savana gram?neo-lenhosa do tabuleiro. O cap?tulo 2, intitulado Considera??es sobre a flor?stica de uma comunidade sav?nica no Rio Grande do Norte, Nordeste do Brasil: Subs?dio de ?rea-chave para a conserva??o foi submetido ? Revista Natureza e Conserva??o. Teve como objetivo contribuir para melhorar o conhecimento sobre a flora do Rio Grande do Norte, identificando poss?veis esp?cies raras e, assim, expandir as ?reas-chave de biodiversidade no Brasil. Os dados obtidos indicaram que: i) das 94 esp?cies encontradas na ?rea de estudo, 39 foram registradas pela primeira vez para o Rio Grande do Norte; ii) dessas cita??es in?ditas para o estado, as esp?cies Stylosanthes montevidensis Vogel (Fabaceae) e Aristida laevis (Nees) Kunth (Poaceae) s?o indicadas, tamb?m, pela primeira vez para a Regi?o Nordeste do Brasil; iii) ocorrem na ?rea 24 esp?cies end?micas do Brasil; iv) Aspilia procumbens Baker (Asteraceae) registrada na ?rea ? considerada uma esp?cie restrita e microend?mica do Rio Grande do Norte, ou seja, esp?cie rara; v) Aspilia procumbens ? tamb?m apontada na categoria das esp?cies criticamente em perigo e Stilpnopappus cearensis Hubber (Asteraceae) uma esp?cie vulner?vel a extin??o. O presente estudo aponta um novo dom?nio citoecol?gico para o Rio Grande do Norte e apresenta o potencial da ?rea em contribuir com os s?tios de signific?ncia global para conserva??o de biodiversidade, seja no ?mbito local, regional e nacional. Isso contribuir? para responder alguns dos objetivos fixados pela Estrat?gia Global para a Conserva??o de Plantas e da Conven??o sobre Diversidade Biol?gica, tal como, o invent?rio da diversidade vegetal, em uma regi?o com pouca coleta, que fornecer? dados que contribuem para quest?es e temas relativos ? biodiversidade.

Full textThe protected areas are created for conservation to nature. The way they associate with the communities and visitors are essential to its objectives are achieved. This study aims to analyze how tourism is developed in the. The Recifes dos Corais Protected Area (APARC) through the identification of the image that tourists and residents have with respect to Parracho of Maracaja? and knowledge of the factors that contribute to a satisfactory visit of tourists. For this was an exploratorydescriptive study with quali-quantitative approach, with 236 tourists and 70 residents of the district of Maracaja?, using questionnaires and interviews. Data analysis techniques were used and percentage of arithmetic, factor analysis and content analysis. The results showed that the importance and significance attributed by residents to Parracho related to economic gains. Information on the APARC and on their standards are not done efficiently and contribute to negatively impact the site. The profile of tourists is not the most appropriate for a protected area. The dimensions of satisfaction to the tourists demonstrated the need for actions to be undertaken by the administration of APARC. Conclude that the image that the residents and tourists have of APARC is not conducive to the image of a protected areas. The tourists are satisfied with the tour in APARC, however, the dimensions of satisfaction are not consistent with the conservation of the site

Full text
Real log and external defect data was obtained from the Forest Service Northeastern Research Station in Princeton, West Virginia for red oak (Quercus rubra, L.) logs. These data were analyzed to determine distributions for log and external defect attributes, and the information was used in the program to assure realistic log generation. An attempt was made to relate the external defect attributes to internal defect characteristics such as volume, depth, and angle. CT scanning was used to obtain internal information for the five most common defect types according to the Princeton log data. Results indicate that external indicators have the potential to be good predictors for internal defect volume. Tests performed to determine whether a significant amount of variation in volume was explained by the predictor variables proved significant for all defect types. Corresponding R2 values ranged from 0.39 to 0.93. External indicators contributed little to the explanation of variation in the other dependent variables. Additional predictor variables should be tested to determine if further variation could be explained.

Full textGlaciers are sensitive indicators of climate change, those marginal and proglacial areas show several changes due to glaciers retraction. Having this in mind, this thesis proposes a hydrological and geomorphological development model for the proglacial zone of a glacier in the south of the King George island, South Shetland Islands, Antarctica in the period between the Little Ice Age and 2017. The relief compartmentation and proglacial geomorphological mapping was done using a Digital Elevation Model generated from TanDEM-X images and a QuickBird image from 2008, in addition to field sediment samples. For the characterization of the ice phenology of the proglacial lakes surface, a correlation of the net surface area, obtained from 2011 TerraSAR X images, was made with temperature, precipitation and wind variables. The evolution of the glacier (locally called Collins Glacier) until 2070 was elaborated using the methodology by Ruckamp et al. (2011). The compartments in the peninsula where the glacier is located (Fildes Peninsula) are plateaus and depressions that have U paleovalley sand amphitheatre valleys as main forms later reworked by melting channels and intemperic processes. The proglacial area is not homogeneous and the glacier front has different environments that were mapped in this thesis in sectors. The glacier eastern sectors are the most dynamic ones, as they have several melting water channels, features like flutings and moraines of recession. In the scenario for the future behaviour of the glacier, it is possible that these areas that will be the first ones to present retraction, until 2030 It is probable that in the future, with the retraction of the glacier, due to the configuration of the subglacial relief, there will be formation of lakes, flooded areas and channels in their more concave portions and more time for operation of the paraglacial processes. The sectors orientated to the Drake Passage indicate an active glacial system with capacity to transport material of different sizes and quantity. In the future this area, due to subglacial relief and hydrology, probably will not have the formation of lakes and features like flutings or moraines of recession, characterizing itself as more stable. Regarding the current lake formation, 7 of the 15 lakes analysed for the 2011 summer presented a significant correlation (ρ greater than 0.4) with temperature, while 11 lakes responded significantly to precipitation. The lakes reached the maximum net surface area at the end of February and frozen completely at the beginning of April. The spatial variation scenario of the Collins Glacier front reveals the continuity of the retraction process for the coming decades, with a loss of 35% of its area by 2070. At the first moment, the retraction in the proglacial zone will form an unstable area with a high amount of sediments in the channels. In this phase, vegetation fixation will increase the infiltration of melting water into the soil (formation of floodwaters), increase of soil strength and shear until the landscape reaches a stable phase, with indications of periglacial activity between 2050 and 2070.

In this paper, we analyzed the Brazilian subterranean fauna, in relation to the actual conservation status, considering the knowledge of its biodiversity, threats to the conservation of this environment and the current legislation relevant to our speleological heritage. The work was divided into chapters, for publication purposes. In chapter I, we present faunal lists of Brazilian troglobitic species (with formal descriptions and not yet described, totaling a minimum of 252 species), their distributions, besides the main causes of destruction / threat of subterranean realm. Still, we propose the Serra do Ramalho, southwestern Bahia state, as a priority area for conservation, since the pressure mining and other factors could decimate the caves of this region biologically important. In chapter II, we discuss about the difficulties of species inclusion in the Red List, and its effective protection, with a case study of Brazilian troglobitic fishes. Problems such as the taxonomic impediment, geographical variations and inclusion only of binomials (Genus species) are discussed. In chapter III, we elected a new hotspot for neotropical subterranean fauna, quartzitic caves from Igatu, in the center region of Chapada Diamantina, central Bahia state. In addition, we tested one of the items of the Instrução Normativa No. 2 of Decreto 6640, which legislates about environmental impact studies of Brazilian caves and we demonstrate that there is not any protectionist law for our subterranean environment.
No presente trabalho, analisamos a fauna subterrânea brasileira, em relação ao seu status de conservação atual, contemplando o conhecimento de sua biodiversidade, as ameaças à conservação deste ambiente e a atual legislação pertinente ao nosso patrimônio espeleológico. O trabalho foi dividido em capítulos, para fins de publicação. No capítulo I apresentamos listas faunísticas de troglóbios brasileiros (com descrições formais e os ainda não descritos, totalizando um mínimo de 252 espécies), suas distribuições, além das principais causas de destruição/ameaça do meio subterrâneo. Ainda, propomos a região da Serra do Ramalho, sudoeste da Bahia, como uma área prioritária para conservação, visto que a pressão minerária e outros fatores podem dizimar as cavernas dessa região, biologicamente importantes. Para o capítulo II, versamos sobre as dificuldades de inserção de espécies às Listas de Fauna Ameaçada de Extinção e efetiva proteção destas, com um estudo de caso de peixes troglóbios brasileiros. Problemas como o impedimento taxonômico, variações geográficas e a inserção somente de binômios (Gênero espécie) são abordados. No capítulo III, elegemos um novo hotspot de fauna subterrânea neotropical, as cavernas quatzíticas de Igatu, no centro da Chapada Diamantina, Bahia central. Além disso, testamos um dos itens da Instrução Normativa nº 2 do Decreto 6.640, o qual legisla sobre as cavernas brasileiras em estudos de impactos ambientais e mostramos que nenhuma lei ambiental para o meio hipógeo é protecionista.
