Um rio e suas gentes: ocupação e conflitos nas margens do rio Turiaçu na fronteira entre Pará e Maranhão (1790-1824)

Esta dissertação objetiva discutir o processo de ocupação na região do Turiaçu na fronteira entre Pará e Maranhão entre 1790 e 1824. Inicialmente este estudo recupera os esforços colonizadores da administração portuguesa de D. Francisco de Souza Coutinho, o ilustrado governador da Capitania do Pará. Com ele foram intensificadas a cessão de terras e suas formas de controle. Estradas foram abertas, localidades mudaram de lugar ou função e povos indígenas reordenados e deslocados. Legalmente, a região do Turiaçu foi ocupada por meio de doação de terras via concessão e confirmação de cartas de sesmarias ainda em meados do século XVIII. Contudo também existiram outras formas de ocupação e organizações desenvolvidas por índios, negros e homens brancos pobres. Este estudo analisa os múltiplos embates sociais, territoriais e identitários ocorridos entre as diversas populações que se concentraram na região, sobretudo nos anos finais do período colonial até a independência e adesão do Grão-Pará a ela.

Reprodução e morfologia de Haddadus binotatus (Spix, 1824) (Anura, Craugastoridae) no litoral do Estado de São Paulo

Haddadus binotatus é uma espécie endêmica de Mata Atlântica e ocorre desde o sul de Pernambuco até o Rio Grande do Sul. Apesar da sua ampla distribuição pouco se conhece da história natural dessa espécie. Haddadus binotatus apresenta desenvolvimento direto e ovos são depositados sob a serapilheira ou sob troncos caídos. Há dimorfismo sexual, sendo as fêmeas maiores do que os machos. O objetivo desse estudo é conhecer os padrões reprodutivos de populações de H. binotatus no continente e em ilhas do litoral do estado de São Paulo. Os objetivos específicos são: 1) avaliar as diferenças morfológicas entre populações de H. binotatus entre ilhas e entre ilhas-continente, 2) avaliar se há dimorfismo sexual em cada população, e 3) comparar os padrões reprodutivos entre populações insulares e continentais. Neste estudo, foram utilizados exemplares de H. binotatus, depositados na coleção de Anfíbios (CFBH), do departamento de Zoologia, Instituto de Biociências, UNESP, Campus de Rio Claro. Os exemplares são provenientes de uma localidade no continente (São Sebastião) e três ilhas (Couves, Queimada Grande e Ilhabela). Os exemplares provenientes das ilhas, com exceção daqueles da Ilha das Couves, foram maiores do que os da Juréia. Houve dimorfismo sexual em todas as populações, sendo as fêmeas maiores. As populações insulares apresentam número de ovócitos menor do que a população do continente (Juréia). O número de ovócitos semelhante aos da população da Juréia foi registrado para uma população em Minas Gerais, reforçando o padrão de que populações insulares têm desovas menores. No entanto, não houve diferença no tamanho dos ovos. As diferenças encontradas para as populações insulares podem ser resultado de recursos mais limitados como espaço e alimento, pelo tamanho das presas e/ou ausência de predadores.

The Priestley-Taylor parameter α for the Amazon forest

Priestley and Taylor provided a practical formulation of the partitioning of net radiation between heat flux and evaporation contained within a parameter α. Their model (PTM) needs verification under a range of environmental conditions. Micrometeorological data sets collected over the Amazon forest at the Ducke Reserve site (2°57′S; 59°57′W) gave an opportunity to evaluate α. Evidence presented here and by others shows that there is pronounced diurnal variation in α, with minimum values around midday and maximum values in the morning and evening hours. During unstable and stable conditions in the daylight hours, the Bowen ratio (B) varied from 0.10 to 0.57 and -0.71 to -0.08, respectively, whereas α varied from 0.67 to 1.16 and 1.28 to 3.12, respectively. A mean value of α = 1.16±0.56 was obtained from daytime hourly values for two days. The daily data sets from three expeditions gave a mean of α = 1.03±0.13. This work confirms that α is a function of atmospheric stability over the Amazon forest. Thus the PTM should be applied with caution over time-intervals of one day or less because of the sensitivity to variation in α. The calculated values of α are in general agreement with those reported in literature. © 1991.

Book Review of "Will the Circle Be Unbroken?": Aboriginal Communities, Restorative Justice, and the Challenges of Conflict and Change by Jane Dickson-Gilmore and Carol La Prairie

Over the past decade or two, restorative justice has become a popular approach for the criminal justice system to take in Canada, New Zealand, and Australia. In part, this is due in all three countries to an appalling disproportionality in the incarceration rates for racialized minorities. As the authors of "Will the Circle Be Unbroken?" point out, however, governments have been attracted to restorative justice for cost-cutting reasons as well. A burning question, therefore, is whether restorative justice works.

Review of Harvest for Hope: A Guide to Mindful Eating by Jane Goodall with Gary McAvoy and Gail Hudson

One of the world's preeminent experts on primate behavior, author Jane Goodall now invests her boundless energy traveling and speaking about conservation. After years of studying chimpanzees in the Gombe National Park in Tanzania, Goodall found their very existence threatened by poachers, by encroachment of farming into their habitat, and by global forces far from their wild environment. She is now on a mission to inform the public about what is wrong with our society and its impact on the planet. Harvest for Hope catalogs the problems and provides practical solutions.

Dynamic stabilization of Rayleigh-Taylor instability of ablation fronts in inertial confinement fusion

One of the most important problems in inertial confinement fusion is how to find a way to mitigate the onset of the Rayleigh-Taylor instability which arises in the ablation front during the compression. In this thesis it is studied in detail the possibility of using for such a purpose the well-known mechanism of dynamic stabilization, already applied to other dynamical systems such as the inverted pendulum. In this context, a periodic acceleration superposed to the background gravity generates a vertical vibration of the ablation front itself. The effects of different driving modulations (Dirac deltas and square waves) are analyzed from a theoretical point of view, with a focus on stabilization of ion beam driven ablation fronts, and a comparison is made, in order to look for optimization.

Taylor formula for Kolmogorov equations

After briefly discuss the natural homogeneous Lie group structure induced by Kolmogorov equations in chapter one, we define an intrinsic version of Taylor polynomials and Holder spaces in chapter two. We also compare our definition with others yet known in literature. In chapter three we prove an analogue of Taylor formula, that is an estimate of the remainder in terms of the homogeneous metric.

Numerical and semi-analytical models of sliding masses: application to the 1783 Scilla tsunamigenic landslide

The Scilla rock avalanche occurred on 6 February 1783 along the coast of the Calabria region (southern Italy), close to the Messina Strait. It was triggered by a mainshock of the Terremoto delle Calabrie seismic sequence, and it induced a tsunami wave responsible for more than 1500 casualties along the neighboring Marina Grande beach. The main goal of this work is the application of semi-analtycal and numerical models to simulate this event. The first one is a MATLAB code expressly created for this work that solves the equations of motion for sliding particles on a two-dimensional surface through a fourth-order Runge-Kutta method. The second one is a code developed by the Tsunami Research Team of the Department of Physics and Astronomy (DIFA) of the Bologna University that describes a slide as a chain of blocks able to interact while sliding down over a slope and adopts a Lagrangian point of view. A wide description of landslide phenomena and in particular of landslides induced by earthquakes and with tsunamigenic potential is proposed in the first part of the work. Subsequently, the physical and mathematical background is presented; in particular, a detailed study on derivatives discratization is provided. Later on, a description of the dynamics of a point-mass sliding on a surface is proposed together with several applications of numerical and analytical models over ideal topographies. In the last part, the dynamics of points sliding on a surface and interacting with each other is proposed. Similarly, different application on an ideal topography are shown. Finally, the applications on the 1783 Scilla event are shown and discussed.
