Com a iminência da construção de mais um trecho do Rodoanel Mário Covas, seu Trecho Norte, tem fechamento um ciclo longo de acumulação de capital na metrópole paulista, de mais de 150 anos, caracterizado pela expansão metropolitana (desigual e combinada) impulsionada pela especulação imobiliária baseada na verticalização do centro expandido e na horizontalização da cidade via loteamentos periféricos. Nesse um século e meio, seu motor foi à crescente financeirização do espaço urbano, tendo como principal conseqüência terrível, a produção de um ambiente construído agressor para sua própria população metropolitana. Como num roteiro de Tarantino, esse presente denota uma sarcástica imagem: hoje, as deseconomias metropolitanas, como as enchentes, o congestionamento e a poluição, tomam o lugar que um dia foi da garoa, de Adoniran Barbosa e dos bairros tradicionais de imigrantes, na produção da identidade paulistana. O novo ciclo de acumulação de capital em gestação não tem como objetivo resgatar essas memórias paulistanas. Ironicamente, esse novo modelo, baseado na suburbanização de alto padrão e no congelamento/urbanização das áreas de loteamento periférico precário e irregular, tem como objetivo construir uma plataforma logística metropolitana apropriada para o que Karl Manheim e tantos outros chamam de fuga do urbano. Pois, o que está em questão é a clara mudança de um padrão de urbanização brasileira (subdesenvolvimento de tipo cepalino) para o do tipo estadunidense, caracterizado por highways que ligam os luxuosos subúrbios ajardinados e as grandes aglomerações médias e populares aos centros degradados das cidades. O presente estudo tem por objetivo, apresentar três dinâmicas espaciais urbanas provisórias dessa fuga do urbano, vetorizadas por três grupos de capital urbano (proprietários da terra/intermediadores financeiros; empresas de construção/incorporação; grupos sociais em geral). A exposição da investigação parte do método dialético e da idéia de espaço geográfico composto por forma, função, estrutura e processo. / With the imminent construction of a Rodoanel Mario Covas, its your Trecho Norte thern section, is closing a long cycle of capital accumulation of more than 150 years, characterized by metropolitan expansion (uneven and combined) driven by speculation based on the vertical expanded center and flattening the town allotments via peripherals. In a century and a half, its engine was the growing financial character of urban space, with the primary tremendous consequence, the production of a built environment aggressor for its own metropolitan population. Like a Tarantino script, the most appropriate image is less promising and more disgustingly sarcastic: today, diseconomies metropolitan areas, such as flooding, congestion and pollution, take the place that was once the garoa of Adoniran Barbosa and the traditional neighborhoods of immigrants in the production of identity in São Paulo. The new cycle of capital accumulation in pregnancy is not meant to recover these memories from São Paulo. Ironically, this new model, based on the suburbanization of high standard and the freeze / urbanizing areas of poor and irregular peripheral housing estate, is to build a logistics hub for the metropolitan appropriate that Karl Manheim and many others call urban trail. For what is at issue is the clear shift from a pattern of urbanization in Brazil (underdevelopment CEPAL type) for the U.S. type, characterized by highways that link the luxurious surroundings and landscaped large clumps and popular medium degraded the centers of cities. This study aims to submit three spatial dynamics of urban temporary escape from the urban, vectorized by three groups of urban capital (owners of the land / financial intermediaries, companies of construction / incorporation; social groups in general). Exposure of the research part of the dialectical method and the idea of geographic space composed of form, function, structure and process.

Freshwater fish species have been introduced into freshwater systems around the world, primarily for aquaculture, ornamental fish trade and sport fishing. Their introduction into estuarine systems is uncommon however, instances do occur and their establishment success and impacts on these estuarine systems is not well documented. The extent of invasion by four freshwater fishes in a RAMSAR listed estuarine system, the Wilderness Lakes, Western Cape was investigated. This thesis determined the relative abundance and distribution of alien fishes in relation to the native fish biota, their establishment success in the system, what factors inhibited their establishment and whether the introduction of alien fishes negatively impacted the native fish biota. The distribution and abundance of fishes were assessed primarily using fyke nets, seine nets and gill nets in each of the lakes, interconnecting channels and the Touw Estuary. The fish fauna was made up of euryhaline marine species comprising 46%, native estuarine species comprising 18%, catadromous species comprising 7% and freshwater alien species comprising 29% of the total biomass sampled. A total of 26 species were sampled in the system, three of which were considered alien; Oreochromis mossambicus, Gambusia affinis and Cyprinus carpio, and Micropterus salmoides were not sampled but confirmed in the system. Establishment success was determined by evidence of: a sustainable breeding population, a wide distribution, abundant in the sampling area, and all size classes of fish sampled. Gambusia affinis and Oreochromis mossambicus have been recorded in the system for a minimum of 13 and 26 years respectively. They were widely distributed and highly abundant and are established in the system. Micropterus salmoides was first recorded in the system in 1985 but abundances have remained low with fish appearing to be limited to Island Lake and Langvlei. Reproduction appeared to be limited by higher salinity and these factors indicated that this was a casual species which relies on repeated introductions for population maintenance. Cyprinus carpio spawned successfully in 2010 and was widely distributed but abundances were still low with a total of 15 fish being sampled throughout the system, and was thus in the establishing phase. As these are considered freshwater alien species, the physico-chemical parameters in the estuarine environment inhibiting the establishment success of the alien fishes were investigated. Gambusia affinis and O. mossambicus were not limited by the physical environment, and while O. mossambicus cannot tolerate temperatures below 11⁰C, temperatures only dropped below its tolerance for a total of two days between February 2010 and February 2011. Cyprinus carpio and M. salmoides were restricted by salinity in Rondevlei and Langvlei but could tolerate salinity in Island Lake and the Touw Estuary during closed mouth phases. While adults appeared to tolerate the salinity in the system, egg and larval development could be affected thus reducing the viability of the population. The abundance of alien fishes did not negatively impact the abundance of native fish species. The interactions between the native and alien fish biota tended towards biotic acceptance where, as alien abundance increased so did native fish abundance. The impacts of the alien fishes on the native fish biota were assessed by comparing the fish community from a study completed in 1985 to the findings of this study. From these two studies there were no apparent negative impacts on the native fish biota and the fish community composition would most likely be structured by estuarine mouth opening events.

Includes bibliography. / The aim of the present study is to produce, and to begin to illustrate the use of, a theoretical model by which varying attitudes to, and experiences of, wilderness may be understood. A classical Jungian developmental framework is utilised for these purposes. The paper begins with brief definitions of the concepts pertinent to this work followed by a fairly comprehensive summary of Neumann's developmental model. The author's model, constructed on this theoretical basis, is then outlined and applied at a mythological level to the attitudes to wilderness manifest in the Judaeo - Christian religions. In the discussion, indications are given as to how the model might be applied at individual and cultural levels. One person's experience of wilderness is interpreted within the context of the theory followed by a brief discussion on the use of the model in informing therapeutic wilderness programming. Traditional North American Indian and contemporary Western attitudes towards wilderness are then briefly interpreted. It is concluded that this paper illustrates the usefulness of a Jungian model in understanding wilderness experience. Within the context of this framework, the value of a developmental perspective is noted.

This study uses a spatial model to visualize LWD mobility areas in an approximate 1km reach of Cummins Creek, a fourth-order stream flowing through an old-growth Sitka spruce-western hemlock forest in the Oregon Coast Range. The model solves a LWD incipient motion equation for nine wood size combinations (0.1m, 0.4m, 1.7m diameters by 1.0m, 6.87m, 47.2m lengths) during the 2-year, 10-year, and 100-year discharge events. Model input variables were derived from a combination of field survey, remotely sensed, and modeled data collected or derived between June 2010 and July 2011. LWD mobility map results indicate the 2-year discharge mobilizes all modeled diameters, but mobile piece lengths are shorter than the bankfull channel boundary. Mobility areas for each wood size combination increases with discharge; 10-year and 100-year discharge events mobilize wood longer than average bankfull width within a confined section of the main stem channel, and mobilize LWD shorter than bankfull width within the main stem channel, side channels, and floodplain. No discharge event mobilizes the largest LWD size combination (1.7m / 47.2). Recruitment process was recorded for all LWD during June 2010, revealing that all mobile wood in the study reach was shorter than bankfull width. Based on these conflicting results, I hypothesize the distribution of wood in Cummins Creek can be described in terms of discharge frequency and magnitude, instead of as a binary mobile/stable classification. Mobility maps could be a useful tool for land managers using LWD as part of a stream restoration or conservation plan, but will require additional calibration.

The purpose of this study was to explore the potential benefits of a primitive wilderness skills intervention (POST) on the therapeutic change process of adolescent females enrolled in a residential treatment center. A qualitative data analysis approach was used. A convenience sample of eight female adolescents was selected by therapist referral. The data were analyzed using open, axial, and selective coding. Data analysis was used to assess participants' progress in the therapeutic change. Further analysis revealed a core theme connecting participants' POST experience with feelings of self-empowerment and reflective connections to their individual therapeutic change process. Constructive enabling was the gerund provided to represent this core theme. Attributes of constructive enabling included the opportunity for creative expression, the recognition of and reliance on social resources, the application of individual effort in challenging situations, the completion of a finished product, and the facilitation of reflective thought.
