Testing alternative models for the conservation of koalas in fragmented rural-urban landscapes

Predicting the various responses of different species to changes in landscape structure is a formidable challenge to landscape ecology. Based on expert knowledge and landscape ecological theory, we develop five competing a priori models for predicting the presence/absence of the Koala (Phascolarctos cinereus) in Noosa Shire, south-east Queensland (Australia). A priori predictions were nested within three levels of ecological organization: in situ (site level) habitat (< 1 ha), patch level (100 ha) and landscape level (100-1000 ha). To test the models, Koala surveys and habitat surveys (n = 245) were conducted across the habitat mosaic. After taking into account tree species preferences, the patch and landscape context, and the neighbourhood effect of adjacent present sites, we applied logistic regression and hierarchical partitioning analyses to rank the alternative models and the explanatory variables. The strongest support was for a multilevel model, with Koala presence best predicted by the proportion of the landscape occupied by high quality habitat, the neighbourhood effect, the mean nearest neighbour distance between forest patches, the density of forest patches and the density of sealed roads. When tested against independent data (n = 105) using a receiver operator characteristic curve, the multilevel model performed moderately well. The study is consistent with recent assertions that habitat loss is the major driver of population decline, however, landscape configuration and roads have an important effect that needs to be incorporated into Koala conservation strategies.

A multihop peer-communication protocol with fairness guarantee for IEEE 802.16-based vehicular networks

Wireless-communication technology can be used to improve road safety and to provide Internet access inside vehicles. This paper proposes a cross-layer protocol called coordinated external peer communication (CEPEC) for Internet-access services and peer communications for vehicular networks. We assume that IEEE 802.16 base stations (BS) are installed along highways and that the same air interface is equipped in vehicles. Certain vehicles locating outside of the limited coverage of their nearest BSs can still get access to the Internet via a multihop route to their BSs. For Internet-access services, the objective of CEPEC is to increase the end-to-end throughput while providing a fairness guarantee in bandwidth usage among road segments. To achieve this goal, the road is logically partitioned into segments of equal length. A relaying head is selected in each segment that performs both local-packet collecting and aggregated packets relaying. The simulation results have shown that the proposed CEPEC protocol provides higher throughput with guaranteed fairness in multihop data delivery in vehicular networks when compared with the purely IEEE 802.16-based protocol.

"Do alto da colina" - a província do Rio Grande do Norte, o comércio, os rios Potengi e Jundiaí e o complexo comercial do Guarapes 1850 - 1900

The commercial complex Guarapes was during the second half of the nineteenth century most commercial street of Rio Grande do Norte province. In that time frame, you can see its flourishing as one of the central places of trade in the province in 1850, and its subsequent abandonment in 1900. This thesis aims to investigate, in its first part, the paths that help to understand, as the context of the expansion of global markets in the second half of the nineteenth century enabled the conditions for the emergence of the commercial complex. However, trade relations established in this province through the commercial complex, even participating in this global environment, reserved particular characteristics in their social and trade relations, as if dealing with a peripheral province, we look at the uniqueness of the relationship occurred in this space. In the second part, we seek to understand the importance that the rivers Potengi and Jundiaí had to install the commercial complex Guarapes in the second half of the nineteenth century. As the geographical position in relation to rivers, enabled this space became flow zone and confluence of goods distributed to the various parts of the interior of the province. We also monitor the process that made these rivers leave the role of mobility and transport relations in this space, giving way the railways and roads shooting. In the third part, we seek to understand the commercial complex Guarapes in focus. Analyzing their spatial distribution on the landscape, and how the spatial organization held at the same time traces of the Brazilian patriarchy exposed by Gilberto Freyre, but also "modern" features, due to the increase of a new culture inserted material in the province. We also seek to understand elements of material culture that was the environment of the complex, and how these materials are important sources for understanding this society under study. We treat from the biggest to the smallest fragments without hierarchize them. Understanding that, the study associated the written sources and materials provide a gain in understanding of everyday these people who lived in that area of the complex in the second half of the nineteenth century.

East Harbor State Park

East Harbor State Park attracted huge crowds on warm summer weekends, as this 1950s lineup of vehicles attests. Automobile travel expanded quickly in the 1950s as the economy grew and roads improved. The cities that provided the region with many of its visitors, like Cleveland, Detroit, and Toledo were at their peak in the 1950s and 1960s.

Análisis de alternativas de mejoramiento de la zona de tolerancia de la ciudad de Cuenca

Para la realización de este trabajo de tesis se plantea un proceso de estudio conformado por 4 capítulos los cuales son: Se inicia con el capítulo de estudio de casos en el cual se analizará las propuestas de mejoramiento de Zonas de Tolerancia que se han llevado acabado en ciudades del Ecuador y otros países, con el objetivo de conocer los procesos y los resultados alcanzados con estos proyectos e identificar parámetros y lineamentos que pueden ser necesarios en esta tesis. En el segundo capítulo se realizará los diagnósticos del lugar para obtener y analizar toda la información necesaria sobre el área de estudio, enfatizando en la Zona de Tolerancia. En el tercer capítulo mediante la información obtenida en los diagnósticos se identificará la problemática existente en sitio la cual estará enfocados en los conflictos existentes en el contexto urbano debido al funcionamiento de usos de suelo. En el cuarto capítulo se realizará la propuesta urbano arquitectónica de mejoramiento de la Zona de Tolerancia que parte de la realización de una imagen objetivo en la que se establecerá los objetivos y estrategias para el mejoramiento de este espacio, además se analizará la alternativa seleccionada para solucionar los problemas existentes en el área de estudio, dentro de este capítulo también se establecerán las determinaciones de usos de suelo, de equipamientos y de vialidad, finalmente se elaborará una propuesta urbano arquitectónica a nivel de prefactibilidad.
