Recreational specialization among visitors to Gros Morne National Park

This study uses the concept of specialization to examine visitors' activities in Gros Marne National Park Reserve, specifically those using the backcountry. An index of activity specialization was created employing generic indicators in an attempt to differentiate among backcountry visitors and between backcountry and frontcountry visitors. Visitor characteristics are described. Preferences for environmental attributes and levels of support for park management strategies by different visitor sub-groups are discussed. -- Questionnaires were distributed to visitors who registered for overnight stays in the backcountry during the summer of 1990 and to visitors who stayed at the 'frontcountry' Green Point campground during the months of July and August, 1990. -- Backcountry visitors are socio-demographically different from Green Point visitors, but are not different in terms of overall activity specialization scores. Differences in hiking specialization and camping specialization were noted between visitors who chose to recreate in different settings within the park. Visitors to untrailed backcountry were more highly specialized hikers than visitors to trailed backcountry, who were more highly specialized hikers than visitors to the frontcountry campgrounds. The reverse pattern was the case for camping specialization. Generally visitors who participated in activities other than hiking or camping had higher specialization scores. -- The specialization index used in this thesis is not a practical tool for park managers. More useful information about park users was obtained from examining visitor comments and by classing visitors into groups based on the park area in which they stayed overnight. Visitors to the untrailed backcountry were found to have similar environmental preferences to visitors to the trailed backcountry with the exception of a stronger preference for physical challenge. Visitors to the trailed backcountry were found to have similar levels of support for management options which include facilities to visitors to the frontcountry. -- Management strategies favored by all visitor groups include the provision of more and better information and interpretation via staff, maps and brochures

Rapid identification of oil contaminated soils using visible near infrared diffuse reflectance spectroscopy

Initially, 46 petroleum contaminated and non-contaminated soil samples were collected and scanned using visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) at three combinations of moisture content and pretreatment. The VisNIR spectra of soil samples were used to predict total petroleum hydrocarbon (TPH) content using partial least squares (PLS) regression and boosted regression tree (BRT) models. The field-moist intact scan proved best for predicting TPH content with a validation r2 of 0.64 and relative percent difference (RPD) of 1.70. Those 46 samples were used to calibrate a penalized spline (PS) model. Subsequently, the PS model was used to predict soil TPH content for 128 soil samples collected over an 80 ha study site. An exponential semivariogram using PS predictions revealed strong spatial dependence among soil TPH [r2 = 0.76, range = 52 m, nugget = 0.001 (log10 mg kg-1)2, and sill 1.044 (log10 mg kg-1)2]. An ordinary block kriging map produced from the data showed that TPH distribution matched the expected TPH variability of the study site. Another study used DRS to measure reflectance patterns of 68 artificially constructed samples with different clay content, organic carbon levels, petroleum types, and different levels of contamination per type. Both first derivative of reflectance and discrete wavelet transformations were used to preprocess the spectra. Principal component analysis (PCA) was applied for qualitative VisNIR discrimination of variable soil types, organic carbon levels, petroleum types, and concentration levels. Soil types were separated with 100% accuracy, and organic carbon levels were separated with 96% accuracy by linear discriminant analysis. The support vector machine produced 82% classification accuracy for organic carbon levels by repeated random splitting of the whole dataset. However, spectral absorptions for each petroleum hydrocarbon overlapped with each other and could not be separated with any classification scheme when contaminations were mixed. Wavelet-based multiple linear regression performed best for predicting petroleum amount with the highest residual prediction deviation (RPD) of 3.97. While using the first derivative of reflectance spectra, PS regression performed better (RPD = 3.3) than the PLS (RPD= 2.5) model. Specific calibrations considering additional soil physicochemical variability are recommended to produce improved predictions

Integrated material practice in free-form timber structures

Integrated material practice in free-form timber structures is a practice-led research project at CITA (Centre for IT and Architecture) that develops a digitally-augmented material practice around glue-laminated timber. The project is part of the InnoChain ETN and has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 642877. The advent of digital tools and computation has shifted the focus of many material practices from the shaping of material to the shaping of information. The ability to process large amounts of data quickly has made computation commonplace in the design and manufacture of buildings, especially in iterative digital design workflows. The simulation of material performance and the shift from models as representational tools to functional ones has opened up new methods of working between digital model and physical material. Wood has gained a new relevance in contemporary construction because it is sustainable, renewable, and stores carbon. In light of the climate crisis and concerns about overpopulation, and coupled with developments in adhesives and process technology, it is returning to the forefront of construction. However, as a grown and heterogeneous material, its properties and behaviours nevertheless present barriers to its utilization in architecturally demanding areas. Similarly, the integration of the properties, material behaviours, and production constraints of glue-laminated timber (glulam) assemblies into early-stage architectural design workflows remains a challenging specialist and inter-disciplinary affair. Drawing on a partnership with Dsearch – the digital research network at White Arkitekter in Sweden – and Blumer Lehmann AG – a leading Swiss timber contractor – this research examines the design and fabrication of glue-laminated timber structures and seeks a means to link industrial timber fabrication with early-stage architectural design through the application of computational modelling, design, and an interrogation of established timber production processes. A particular focus is placed on large-scale free-form glulam structures due to their high performance demands and the challenge of exploiting the bending properties of timber. By proposing a computationally-augmented material practice in which design intent is informed by material and fabrication constraints, the research aims to discover new potentials in timber architecture. The central figure in the research is the glulam blank - the glue-laminated near-net shape of large-scale timber components. The design space that the blank occupies - between sawn, graded lumber and the finished architectural component - holds the potential to yield new types of timber components and new structural morphologies. Engaging with this space therefore requires new interfaces for design modelling and production that take into account the affordances of timber and timber processing. The contribution of this research is a framework for a material practice that integrates processes of computational modelling, architectural design, and timber fabrication and acts as a broker between domains of architectural design and industrial timber production. The research identifies four different notions of feedback that allow this material practice to form

Latin American critical thought. Theory and practice

The resurgence of LATin AmericAn criTicAL thought in the late 1990s and the early twenty-first century has brought about some discoveries that distinguish it from the sociological production of the world. it is a scientific framework that has taken on the features of a new social scientific paradigm. A growing number of authors have aligned themselves with this perspective, with visions that include critical read- ings geared to contributing to transformative social change, in a Latin American context. Thus, we ask ourselves: What are the characteristics that distinguish Latin American critical thought and give it its identity? What are its germinal features and what are its unresolved matters? A distinguishing feature of this thought is its belonging to social sciences, particularly sociology and its traditions of critical theory, whose roots, as gramsci said, do not come from fundamentalist op- position but rather from the acquisition of scientific certainty on the basis of critical analysis (...

Viral Injustice

The COVID-19 pandemic blighted all aspects of American life, but people in jails, prisons, and other detention sites experienced singular harm and neglect. Housing vulnerable detainee populations with elevated medical needs, these facilities were ticking time bombs. They were overcrowded, underfunded, unsanitary, insufficiently ventilated, and failed to meet even minimum health-and-safety standards. Every unit of national and sub-national government failed to prevent detainee communities from becoming pandemic epicenters, and judges were no exception. This Article takes a comprehensive look at the decisional law growing out of COVID-19 detainee litigation and situates the judicial response as part of a comprehensive institutional failure. We read hundreds of COVID-19 custody cases, and our analysis classifies the decision-making by reference to three attributes: the form of detention at issue, the substantive right asserted, and the remedy sought. Several patterns emerged. Judges avoided constitutional holdings whenever they could, rejected requests for ongoing supervision, and resisted collective discharge—limiting such relief to vulnerable subpopulations. The most successful litigants were detainees in custody pending immigration proceedings, and the least successful were those convicted of crimes. We draw three conclusions that bear on subsequent pandemic responses, including vaccination efforts, and on incarceration more generally. First, courts avoided robust relief by recalibrating rights and remedies, particularly those relating to the Eighth and Fourteenth Amendments. Second, court intervention was especially limited by the behavior of bureaucracies responsible for the detention function. Third, the judicial activity reflected entrenched assumptions about the danger and moral worth of prisoners that are widespread but difficult to defend. Before the judiciary can effectively respond to the dangers posed by a pandemic, nonjudicial institutions will have to tolerate large-scale, exigency-driven releases from custody, and judges will have to overcome their empirically dubious resistance to decarceration
