A computational academic integrity framework

L'abast creixent i la naturalesa canviant dels programes acadèmics constitueixen un repte per a la integritat dels protocols tradicionals de proves i exàmens. L'objectiu d¿aquesta tesi és introduir una alternativa als enfocaments tradicionals d'integritat acadèmica, per a cobrir la bretxa del buit de l'anonimat i donar la possibilitat als instructors i administradors acadèmics de fer servir nous mitjans que permetin mantenir la integritat acadèmica i promoguin la responsabilitat, accessibilitat i eficiència, a més de preservar la privadesa i minimitzin la interrupció en el procés d'aprenentatge. Aquest treball té com a objectiu començar un canvi de paradigma en les pràctiques d'integritat acadèmica. La recerca en l'àrea de la identitat de l'estudiant i la garantia de l'autoria són importants perquè la concessió de crèdits d'estudi a entitats no verificades és perjudicial per a la credibilitat institucional i la seguretat pública.

Mixed Reality for Historic Preservation

Digital technologies are becoming widely available to experts in the field of historic preservation. These tools equip experts with the capability to obtain high resolution and accurate information about cultural heritage, which can be accurately reproduced and rematerialized without coming into contact with the physical object itself. This preservation approach is described as non-contact, meaning that it is not invasive to the material integrity of an artifact. Since the turn of the century, stakeholders in the field have increasingly focused their attention on digital technologies for advancing the field. The motivation for experts to preserve cultural heritage with digital technologies starts with the idea of merging the two, and in recent years, innovations in high-resolution digital imaging, recording, processing, modeling and reproduction capabilities have fostered the integration of a virtual environment. Mixed Reality (MR), which the merging of digital and physical worlds, not only allows experts to expand possibilities for preservation interventions once all physical range of actions have been exhausted, but it also makes it possible for experts to intervene digitally before carrying out a preservation treatment. MR can be used as a tool to create hybrid environments for experts and researchers to better manage and understand cultural heritage, which in turn allows them to provide the public with a deeper understanding about cultural heritage. The traditionally object-centric nature of the historic preservation field favors MR over Virtual Reality, since the former engages with the physical site or artifact themselves. By allowing field experts and visitors to visualize scenes in situ from viewpoints that are impossible due to size, content or accessibility issues, the installation of MR’s formless aesthetics engages viewers of cultural heritage through new and innovative ways. The application of MR offers countless strategies for approaching conservation and interpretation projects in historic preservation. But, despite its capacity to enhance the practice of historic preservation, MR poses new technological and methodological questions for the field. As a burgeoning tool and constantly changing field, there have been very few studies conducted on the application of MR to the field of historic preservation. This thesis argues that, on the one hand, MR provides innovative strategies for approaching preservation problems; but on the other hand, the absence of standards, guidelines, and techniques make it difficult to evaluate and propose new projects in the field. As a response to this deficiency, I propose a framework to evaluate and use MR for the preservation of cultural heritage. This framework is first tested to evaluate three case studies, and next, to propose a unique MR strategy for the complex preservation case of the San Baudelio de Berlanga Hermitage in the province of Soria, Spain. This thesis aims to contribute a MR framework and methodology that provides a consistent conceptual approach to MR projects in the field

Valuing biodiversity: Decision support for biosecurity response

This thesis develops a Decision Support System (DSS) to improve biosecurity response decisions affecting indigenous biodiversity. The key elements of the DSS are a synthesis of three components of non-market valuation: choice modelling, a systematic database of values and benefit transfer, with risk simulation to account for uncertainty. The innovative framework is demonstrated in a manual developed for Biosecurity New Zealand analysts for use during the early days of an incursion when time is severely constrained and uncertainty abounds. Theoretical approaches to decision making for environmental resource allocation decisions are reviewed with particular reference to decision support tools including non-market valuation, stated preference techniques, database development and benefit transfer. More complex and time consuming tools such as deliberative support and mediated modelling are also discussed. A framework is developed to quantify biodiversity values for use in Cost Benefit Analysis (CBA). The framework incorporates advanced choice modelling techniques demonstrated through four case studies, a systematic database of biodiversity values and transfer of these values using univariate benefit transfer with theoretical adjustment. The uncertainty in the values captured in the panel version of the Random Parameters Logit (RPL) model is integrated into CBA using risk simulation which utilises the means, standard deviations and correlation coefficients of risky variables to quantify the probability of achieving a positive Net Present Value of different response options. The DSS developed in this thesis has wider application in routine management of pests and diseases and in other resource allocation decisions by public agencies which impact on indigenous biodiversity

Former to Future: Preservation in the U.S. National Parks

abstract: For more than 100 years, the Unite States National Park Service (NPS) has been guided by a mandate to preserve parks and their resources for the enjoyment of present and future generations. But all parks are subject to conditions that may frustrate preservation efforts. Climate change is melting the glaciers. Rising seas are sweeping away protected shorelines. Development projects, accompanied by air, water, light, and noise pollution, edge closer to parks and fragment habitats. The number of visitors and vested interests are swelling and diversifying. Resources for preservation, such as funds and staff, seem to be continuously shrinking, at least relative to demand. Still, the NPS remains committed to the preservation of our natural and cultural heritage. Yet the practice of that promise is evolving, slowly and iteratively, but detectably. Through explorations of legal and scholarly literature, as well as interviews across the government, non-profit, and academic sectors, I’ve tracked the evolution of preservation in parks. How is preservation shifting to address socio-ecological change? How has preservation evolved before? How should the NPS preserve parks moving forward? The practice of preservation has come to rely on science, including partnerships with academic researchers, as well as inventory and monitoring programs. That shift has in part been guided by goals that have also become more informed by science, like ecological integrity. While some interviewees see science as a solution to the NPS’s challenges, others wonder how applying science can get “gnarly,” due to uncertainty, lack of clear policies, and the diversity of parks and resources. “Gnarly” questions stem in part from the complexity of the NPS as a socio-ecological system, as well as from disputed, normative concepts that underpin the broader philosophy of preservation, including naturalness. What’s natural in the context of pervasive anthropogenic change? Further, I describe how parks hold deep, sometimes conflicting, cultural and symbolic significance for their local and historical communities and for our nation. Understanding and considering those values is part of the gnarly task park managers face in their mission to preserve parks. I explain why this type of conceptual and values-based uncertainty cannot be reduced through science.Dissertation/ThesisDoctoral Dissertation Biology 201

Integrative geospatial modeling: combining local and indigenous knowledge with geospatial applications for adaptive governance of invasive species and ecosystem services

Includes bibliographical references.2015 Summer.With an unprecedented rate of global change, diverse anthropogenic disturbances present growing challenges for coupled social-ecological systems. Biological invasions are one such disturbance known to cause negative impacts on biodiversity, ecosystem functioning and an array of other natural processes and human activities. Maps facilitated by advanced geospatial applications play a major role in resource management and conservation planning. However, local and indigenous knowledge are overwhelmingly left out of these conversations, despite the wealth of observational data held by resource-dependent communities and the potential negative impacts biological invasions have on local livelihoods. My integrative geospatial modeling research applied adaptive governance mechanisms of knowledge integration and co-production processes in concert with species distribution modeling tools to explore the potential threat of invasive plants to community-defined ecosystem services. Knowledge integration at the landscape scale in Alaska provided an important opportunity for re-framing risk assessment mapping to include Native Alaskan community concerns, and revealed the growing potential threat posed by invasive aquatic Elodea spp. to Chinook salmon (Oncorhynchus tshawytscha) and whitefish (Coregonus nelsonii) subsistence under current and future climate conditions. Knowledge integration and co-production at the local scale in northeastern Ethiopia facilitated shared learning between pastoral communities and researchers, leading to the discovery of invasive rubber vine (Cryptostegia grandiflora), which was previously unknown to my research team or a number of government and aid organizations working in the region, thus providing a potentially robust early detection and monitoring approach for an invasive plant that holds acute negative impacts on a number of endemic ecosystem service-providing trees. This work revealed knowledge integration and co-production processes and species distribution modeling tools to be complimentary, with invasive species acting as a useful boundary-spanning issue for bringing together diverse knowledge sources. Moreover, bridging and boundary-spanning organizations and individuals enhanced this rapid appraisal process by providing access to local and indigenous communities and fostered a level of built-in trust and legitimacy with them. Challenges to this work still remain, including effectively working at broad spatial and governance scales, sustaining iterative processes that involve communities in validating and critiquing model outputs, and addressing underlying power disparities between stakeholder groups. Top-down, discipline-specific approaches fail to adequately address the complexity of ecosystems or the needs of resource-dependent communities. My work lends evidence to the power of integrative geospatial modeling as a flexible transdisciplinary methodology for addressing conservation efforts in rural regions with mounting anthropogenic pressures at different spatial and governance scales

Knowledge politics and new converging technologies: a social epistemological perspective

The “new converging technologies” refers to the prospect of advancing the human condition by the integrated study and application of nanotechnology, biotechnology, information technology and the cognitive sciences - or “NBIC”. In recent years, it has loomed large, albeit with somewhat different emphases, in national science policy agendas throughout the world. This article considers the political and intellectual sources - both historical and contemporary - of the converging technologies agenda. Underlying it is a fluid conception of humanity that is captured by the ethically challenging notion of “enhancing evolution”
