APRIL Ecosystem Restoration Project: A sustainable model for Indonesian peatlands?

Ceruti, Michael January 2016 (has links)
The growth in global population and the unsustainable business as usual model adopted by private companies in managing land, are causing huge pressures on Indonesian natural ecosystems. The widespread peatland deforestation and degradation affecting Indonesia has been the leading cause of biodiversity loss, decrease of vital ecosystem services, land subsidence, fires and increased impoverishment of local communities. In response to this issue, the Indonesian government, supported by civil society and scientists, issued in 2004 the Ecosystem Restoration Concession license, a new approach of managing logged out production forests in order to reverse and restore deforested, degraded and damaged ecosystems. In 2013, the Indonesian second largest pulp and paper company, APRIL acquired this licence and launched one of the biggest and most ambitious restoration projects in the country, called RER. This project was implemented in the Kampar Peninsula, Riau province, Sumatra, a vast peatland area unique for its ecosystem services and its flora and fauna species. The purpose of this thesis was to investigate the sustainability of the project’s management, conservation and development model. Field observations and qualitative semi-structured interviews were conducted on various groups of stakeholders. The study showed that, although the project has generated various benefits, thus having the potential of exceeding the environmental, social and economic costs in the future, several challenges, such as managing land, providing alternative livelihoods and including the participation of local communities were reported. If these problems are not successfully addressed, they risk jeopardising the success of the project and therefore its opportunity of becoming sustainable and widespread.

A model of food forestry and its monitoring framework in the context of ecological restoration

Park, Hyeone 22 December 2016 (has links)
Food forestry has grown in its popularity in Canada, the United States and the United Kingdom, which it has not been traditionally practiced before, for its potential to produce healthy food, to create habitat for wildlife species, to reconnect people with nature and to provide various ecosystem services such as carbon storage. Diverse food forest projects are conceived from urban food initiatives to integrated conservation and restoration planning. Currently, the Galiano Conservancy Association is creating two food forests in the heart of a mature Coastal Douglas-fir landscape on Galiano Island, British Columbia, which is protected under a conservation covenant, in pursuit of sustainable food production, education and contribution to ecological restoration and conservation efforts. To investigate the relationships between emerging food forestry and ecological restoration and to identify key indicators to measure best practices of food forestry in the context of ecological restoration, I conducted 16 semi-structured interviews with food forestry and ecological restoration experts. In addition, I conducted a workshop with the Conservancy stakeholders to develop a comprehensive and systematic monitoring framework for their food forest projects. My studies suggest that restoration principles and resilience thinking can provide guidelines for restorative food forestry. Food forestry may serve as an innovative restoration tool to restore urban landscapes where lack significant opportunities for conventional restoration. A generic monitoring framework for food forestry could be adapted by other projects, yet this will require the process of defining goals and objectives of a given project and assessing landscape contexts and the organization’s capacity to monitor. / Graduate / soph.park@yahoo.ca

The Restoration Players: Their Performances and Personalities

Rosenbalm, John O. 05 1900 (has links)
Some of the older actors of the Restoration provided a link between the pre- and post-Commonwealth stages by preserving their craft during the years from 1642 to 1660, despite the harsh and numerous restrictions enacted by the Parliament. Some of the younger players, on the other hand, quickly mastered their art and continued the tradition preserved for them by men such as Charles Hart and Michael Mohun. The greatest actors and actresses of the period certainly influenced the direction of Restoration drama in several ways. Thomas Betterton and Elizabeth Barry were so skilled that on several occasions leading dramatists asked their advice about dialogue, character development, and stage business. Other actors, such as Samuel Sandford and Colley Cibber, developed into great character actors, and the dramatists created roles especially suited to their talents. William Congreve 's admiration for Anne Bracegirdle's talent and beauty perhaps contributed substantially to the creation of the character of Millimant in The Way of the World. Actors such as William Penkethman and Joseph Haines often insured a play's success by their antics on the stage. In addition to the major figures of the period, a substantial number of competent minor actors and actresses mastered the character roles which appear with frequency in much Restoration drama. The Restoration players exerted an influence on both the direction and content of the drama of the period. A better understanding of their performances and personalities could well lead to a better understanding of the drama itself. I have followed the alphabetical listing of the actors and actresses given in Part I of The London Stage, making a few additions where I found them necessary. For the most part, each entry contains information on the player's first and last recorded performances and on his best roles. Whenever possible I have included commentary about his ability. In addition, I have tried to provide data about the character and personality of each player when possible. In some instances I felt that the physical appearance was important and included that information. Much of the information in each entry comes from Restoration and eighteenth century sources. John Downes's Roscius Anglicanus and Thomas Davies' Dramatic Miscellanies were especially valuable, as was John Genest's Some Account of the English Stage. In the twentieth century, the works of John Harold Wilson and Sybil Rosenfeld were very helpful. Finally, the massive scholarship of The London Stage pervades this dissertation. Without that work my task would have been impossible.

Two urban corners : a design exploration for the Holloway block / 2 urban corners : a design exploration for the Holloway block

Cabot, Thomas Dudley January 1982 (has links)
Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1982. / MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH. / Includes bibliographical references. / This thesis explores built possibilities for two public street corners at the Holloway Block in Burlington, Vermont The site is at the historic commercial center of the town, and consisted until recently of abandoned buildings. The author and a partner recently purchased the site and renovated the existing structures for retail and office uses. The two corners, bookends for the block, were vacant at the time of purchase. One is in reality occupied by a building designed by architect Turner Brooks. The other will be built upon in the near future, and the author anticipates the opportunity to make the design. The programs for both buildings are based on amateur analysis of marketing and growth studies made by others. The block is largely within a National Historic District, which imposes design constraints. The designs grow from a brief discussion of the geological, climatic and historical context, and from a brief attitudinal discussion of public urban streets. / by Thomas Dudley Cabot III. / M.Arch.

Nature soundscapes and cognitive performance in an office environment

Pittman, Maxwell 23 April 2019 (has links)
Research suggests that interacting with nature has positive psychological, physiological, and cognitive benefits. Views to nature, interacting with nature, and other visual nature stimuli have been widely studied. However, nature soundscapes have received less attention; and the limited research that has been published has mixed findings. The present study assessed whether nature soundscapes influenced performance on cognitive and affective assessments. Participants completed the Flanker task, the Stroop task, a Visual Search task, and the Positive and Negative Affect Schedule, while exposed to either nature sounds alone, nature sounds with outdoor views, or neither. No statistically significant differences in performance were found for any of the three conditions, on either the cognitive and affective assessments. These findings indicate that the relation between nature sounds and cognition is more complex than originally presumed, and potential future directions are discussed. / Graduate / 2020-04-11

Taipa, canela preta e concreto: um estudo sobre a restauração de casas bandeiristas em São Paulo / Taipa, blackleg and concrete: A study on the restoration of the bandeirantes houses in Sao Paulo

Mayumi, Lia 21 March 2006 (has links)
Partindo do pressuposto da existência de um paradigma constituído pelo modelo pioneiro de restauração de casas bandeiristas estabelecido pelo IPHAN desde os anos iniciais de sua atividade em São Paulo, o presente trabalho pretende realizar uma análise, em relação àquele paradigma, dos projetos e obras de restauração de cinco casas bandeiristas pertencentes à Prefeitura de São Paulo. Adotando a hipótese da sucessão cronológica de três momentos de continuidade, de diluição e de abandono do paradigma , o presente trabalho busca verificá-la através da análise dos projetos e das obras de restauração realizadas nos exemplares selecionados. Esses projetos e obras foram orientados inicialmente pelo IPHAN Instituto do Patrimônio Histórico e Artístico Nacional e depois, pelo DPH Departamento do Patrimônio Histórico da Prefeitura de São Paulo no período compreendido entre as décadas de 1950 e 2000. / This work analyses the architectural restoration of five bandeirantes houses in the city of São Paulo. Those restoration works, which took place between the years 1950 and 2000, were accomplished by the IPHAN Institute for National Artistic and Historical Heritage and the DPH Historical Heritage Department of the City Government of São Paulo. The work aims to identify and characterize both the conceptual and technical models that guided those restoration works. Assuming that IPHAN has developed a conceptual and technical paradigm in the restoration of this architectonical type, the work investigates the paradigms permanence extent in those five houses and, reversely, its vanishing along the almost fifty years comprising this study.

Removing Dams, Constructing Science: Watershed Restoration Through a Socio-Eco-Technical Systems Lens

Grabowski, Zbigniew Jakub 08 August 2018 (has links)
Ecological conservation and restoration in the anthropocene must struggle with overlapping drivers of biodiversity and cultural loss; ruptures of the ecological environment mirror ruptures of human relationships with nature. And yet technology cannot remove humans from nature; technological and infrastructural reconfigurations of nature create new vulnerabilities and risks for humans and ecosystems alike. How can conservation and restoration science productively grapple with complex infrastructure systems and decision-making processes as biophysical and social drivers of ecosystem change? Using dam removals in the USA and in the Mid Columbia River region of the Pacific Northwest, this dissertation develops a conceptual framework for Social, Environmental, and Technological Systems (SETS), and applies it at three spatial and temporal scales to the practice of dam removal as a river restoration strategy. Drawing upon existing data sets, as well as biophysical, document, survey, and interview data this dissertation addresses how dam removals have functioned in the context of the social histories of river restoration programs, examines how these restoration programs must continue to renegotiate the human relationships with nature through the infrastructure systems that enable certain forms of existence while precluding others. Of particular interest is how restoration programs have increasingly functioned to deliver novel infrastructure solutions, while ignoring longer-term changes in ecological structure and function due to infrastructure development; in other words, the infrastructural work of restored ecosystems, and the infrastructural blind spots of restoration programs. How restoration planning considers, or does not consider, infrastructural blind spots, is indicative of not only the biophysical drivers of threatened and endangered species loss, but also the political dynamics of decision making at large, and the power-knowledge relationships constituting legitimate and relevant knowledge in the decision making space. In the Pacific Northwest, there appears to be a tipping point of social convention in centering treaty rights and obligations vis-a-vis ongoing processes of colonization and institutionalized scientific expertise. Ecological restoration will only be successful if it addresses both engineered infrastructures and social justice.

Charters and the Ethics of Conservation: A Cross-Cultural Perspective

Rowney, Barry January 2004 (has links)
The growing realisation of national identity in the face of the threatening envelopment of globalisation has been one major inducement for the increasing practice of conservation of the world's built heritage. This study examines contemporary practices of heritage conservation, analyses their assumptions and theories, and critiques their guiding instruments, the Charters. It adopts a cross-cultural perspective to assess the merits, validity and agency of the most recognised Charters, to discuss their various adaptations, particularly in the Syrian context, and to reveal their Eurocentric focus and indifference to cultural concerns. The study also identifies the inadequacies of the Charters with regard to ethics and morality and proposes a code of ethics for urban conservation. The study focuses on the notion of authenticity that has been an issue of debate since the Nara Conference on Authenticity in 1994. Although arising from, and specifically aimed at, World Heritage Listing, authenticity is recognised as a complex issue dependent on cultural understandings. The study adopts the view that authenticity judgements are linked to a great variety of sources of information, such as form, design, materials, function, traditions, techniques, use, location and spirit that are context-related. It articulates a wide scope for conservation practices at the architectural, urban and archaeological levels, negotiating the breadth and depth of authenticity issues beyond mere fabric and function. The study promotes a dynamic view of authenticity, one that acknowledges socio-cultural change with its inevitable impact on the conditions and conservation of historic environment. The ethical code this study presents places the responsibility on the conservator to ensure the continued conservation and stewardship by the resident society. The study argues that both the Venice and Burra Charters, being the most recognised conservation instruments, are pitched at individual monuments. It critiques the widely held assumption that maintains applicability of these Charters to area and urban conservation. It draws attention to the paradox that while these Charters address the ethics of conservation their scope are limited to individual buildings, whereas the Charters concerned with urban and area conservation, like the Washington Charter, are inadequate with regards to ethical and cultural issues. By articulating a code of ethics for urban conservation, the study attempts to bridge a significant gap. The study draws on, and contextualises its arguments in, the rich and varied archaeological and urban heritage of Syria, a country that is still coming to terms with the practices, implications and problems of heritage conservation. / Thesis (Ph.D.)--School of Architecture, Landscape Architecture and Urban Design, 2004.

Improvements To Neural Network Based Restoration In Optical Networks

Turk, Fethi 01 June 2008 (has links) (PDF)
Performance of neural network based restoration of optical networks is evaluated and a few possible improvements are proposed. Neural network based restoration is simulated with optical link capacities assigned by a new method. Two new improvement methods are developed to reduce the neural network size and the restoration time of severed optical connections. Cycle based restoration is suggested, which reduces the neural network structure by restoring the severed connections for each optical node, iteratively. Additionally, to reduce the restoration time, the necessary waiting time before the neuron outputs fire for the propagation delay over the network is computed and embedded in the control structure of the neural network. The improvement methods are evaluated by simulations in terms of restorability, restoration time, network redundancy and average length of restoration paths for different failure cases and different security requirements.
