Retributive Theory’s Restorative Corollary

Farooqi, Nadeem U 01 January 2015 (has links)
According to retributivism, what justifies punishment is a wrongdoer's desert. Critics argue that retributivists fail to provide sufficient justification for punishment. Herbert Morris offers the type of justification critics demand, providing an account of punishment that: 1) values autonomy, and 2) appeals to the principle of fairness. Punishment, in this account, restores equilibrium of benefits and burdens with respect to autonomy. Since punishment largely ignores the autonomy of the victim, however, punishment alone seems unable to ensure justice. In order to provide a more complete account of justice, I contend that one must be committed to retributivism and restoration. Indeed, restoration of the victim’s autonomy may be understood to be part of a completed deployment of the rationale for punishment.

The interplay of habitat and seed size on the shift in species composition in a fragmented Afromontane forest landscape: Implications for the management of forest restoration

Babale, Aliyu January 2014 (has links)
The Cameroon Highlands that run along the Cameroon-Nigeria border are an important source of biodiversity. Not only are they rich in species and high in endemics, but biota from West Africa have not been studied as extensively relative to other parts of the Afrotropics, or the tropics in general. Threatening these rare and diverse habitats is anthropogenic pressure, which fragments forests and changes local animal communities. This thesis wished to address the impact of humans on seed dispersal and recruitment processes on selected tree species in forests on the Mambilla Plateau - a montane region in Nigeria's north-east. Research was conducted at Ngel Nyaki Forest Reserve, a conservation area established by the Nigerian Montane Forest Project. The reserve comprises a moderately-large forest patch (Ngel Nyaki Forest) and many small riparian fragments embedded in a grassland matrix. Cattle grazing and burning of this grassland are major threats to the survival of forest in this area.Hunting of local wildlife for bushmeat is also of concern, considering many of the region’s large-mammalian fauna are now locally extirpated (e.g. elephants) or at low abundances (many primate species). Loss of large-bodied frugivorous species has the potential to negatively impact the recruitment of large-seeded tree species that solely rely on them as seed dispersers. In this study, the ability for scatterhoarding rodents to act as surrogate dispersers for large-seeded species is tested. While much research has been carried out on secondary rodent dispersal in the Neotropics, work in the Afrotropics is still in its infancy. Because the outcome of plant-rodent interactions (i.e. predated or dispersed) may vary with season, habitat, or traits of the seed species in question, a number of experiments were established to quantify how local rodents at Ngel Nyaki may or may not be acting as effective dispersers. Additionally, the benefits of rodent dispersal were examined by creating an experiment that simulated secondary dispersal on seedling recruitment. The results of this study demonstrated that rodents can act as effective dispersers in Afromontane forests, but this is influenced by habitat, seasonal abundance of resources, and palatability of seed species. Furthermore, it was demonstrated that burial of seeds by rodents can increase the establishment probability of a seed by protecting it from removal by other rodents. However, while rodents play a strong driver of seed survival, it was also demonstrated that seedling mortality factors (such as herbivory) can also be heavy filters to seedling success. It is hoped that the results of this study will help to inform better management decisions and understand how the composition of the forest might change in the future.

Roles of aesthetic value in ecological restoration : cases from the United Kingdom

Prior, Jonathan David January 2013 (has links)
Ecological restoration has been identified as an increasingly important tool in environmental policy circles, from reversing species loss to mitigating climate change. While there has been a steady rise in the number of research projects that have investigated social and ecological values that underpin ecological restoration, scholarship has predominantly been carried out at the theoretical level, to the detriment of engaging with real-world ecological restoration projects. This has resulted in generalised and speculative accounts of ecological restoration values. This thesis seeks to address this research gap through a critical analysis of the roles of aesthetic values in the creation and implementation of restoration policy, using three different case studies of ecological restoration at the landscape level in the United Kingdom. I employ interdisciplinary research methods, including semi-structured interviews, interpretive policy analyses, still photography, and sound recording techniques, to better understand the multi-sensorial qualities of ecological restoration. I trace the role of aesthetic value from the initial development of restoration policy through to the management of the post-restoration landscape, considering along the way how aesthetic values are negotiated amongst other types of social and ecological values, how aesthetic values are measured, articulated, and projected onto the landscape by restoration policy makers, and the ways in which aesthetic values are applied through design and management strategies across each site. Throughout the thesis, I engage with a number of current research themes within the ecological restoration literature that intersect with aesthetic value, such as the use of ‘native’ and ‘non-native’ species in landscape restoration, and the procedure through which landscape reference models are selected. I also address hitherto unasked spatial questions of ecological restoration, including an examination of the aesthetic relationships between a restoration site and adjacent landscapes, and the application of spatial practices to regulate certain forms of post-restoration landscape utility. I demonstrate that aesthetic values play a multitude of different roles throughout the restoration process, and ultimately show that as aesthetic values are captured and put to use to different ends through policy, they are inherently bound up with competing ethical visions of society-nature relationships.

Movers and shakers : the affects of vibrations on historic structures / Affects of vibrations on historic structures

Anthony, David January 1997 (has links)
Preservationists and historic sites managers need to be aware of the affects of excess man-made vibrations on historic structures. The purpose of this creative project is to examine those affects and identify some methods to mitigate them. To write this project, it was necessary to search through available literature identifying past research and studies on this subject. Research was culled from various sources examining the affects of vibrations on new and historic structures and are presented here in one volume.The affects of vibrations on historic structures is not a subject that is well represented in preservation or structural engineering literature. The information currently available is scattered through various sources. Thus, there is the lack of a single reference examining the affects of vibrations on historic structures. This project is meant to be used as a reference for historic preservationists, house museum curators, and historic sites managers who seek information about vibration effects and possible solutions to their vibration problem. / Department of Architecture

The development of exterior maintenance guidelines for lighthouses in six geographic regions

Schweikert, Carol Ann Johnson January 1995 (has links)
United States Lighthouses are being decommissioned by the United States Coast Guard because they are no longer needed as navigational aids. Government agencies and non-profit groups untrained in preservation are assuming control of these aids. These groups need assistance to adequately maintain the lighthouse and prevent major deterioration problems. About 300 managers of lighthouses were contacted for information on how they maintain their lighthouse, including information on shoreline erosion. About 120 replies were received containing maintenance and restoration information, drawings and photographs. The lighthouse system was divided into six geographic regions with similar climatic conditions for closer examination. The replies from the lighthouses regarding common deterioration problems in the construction materials and environmental conditions were used to develop general maintenance guidelines for each geographic region. Lighthouse managers can use these maintenance guidelines to assist them in preserving their lighthouse.Shoreline erosion was examined closely because of its destructive capability. Cape Hatteras Lighthouse in North Carolina was used as a Case Study in combatting erosion. / Department of Architecture

An assessment of genomic sequence restoration in Arabidopsis thaliana

Khalid, Aaron Munir 06 November 2014 (has links)
A fundamental tenet of classical Mendelian genetics is that allelic information is stably transmitted from parent to progeny. Work in our laboratory has revealed a novel exception to this law where Arabidopsis thaliana plants homozygous for the recessive organ-fusion mutation hothead (hth) gave rise to phenotypically and genotypically wild-type (HTH) progeny at high frequencies. We have coined the term restoration to describe this phenomenon, since the reverted HTH allele was not detectable in the parental genome but was present in a recent ancestor (the grandparent). Recent work in our laboratory has demonstrated that 45-94 bp insertions and deletions (indels) can also restore, irrespective of their genomic location. The work described in this thesis expands our understanding of restoration by characterizing previously identified non-parental loci at the molecular level, and monitoring the inheritance of native and transgenic alleles in hth mutant and wild-type genetic backgrounds. Two ??? eight hundred bp genomic intervals containing non-parental loci were cloned and sequenced. This revealed that the tracts of sequence which had been reinstated were identical in phase and sequence composition to the corresponding grandparental sequences. Furthermore, molecular markers flanking non-parental loci were profiled across 80-90 kb chromosomal regions. In all cases, the flanking markers reverted concurrently, suggesting that restoration can affect comparatively large genomic regions. However, it is not clear if flanking markers revert as a result of multiple independent events or, alternatively, are the result of one continuous restoration event. A number of individuals studied in this thesis are genetic mosaics, wherein the restoration events are localized within a single individual. Genetic mosaicism cannot be attributed to pollen contamination, and provides the strongest evidence to-date that restoration is a genuine and novel biological phenomenon. The inheritance of a transgenic allele and two native alleles was monitored in pedigrees compromising a number of distinct ancestries in hth-4, hth-8, and wild-type genetic backgrounds. Although none of the F3 progeny exhibited atypical segregation of the investigated alleles, molecular screening may have revealed localized (mosaic) restoration of the transgenic marker. However, these results remain inconclusive based on results obtained in a negative control experiment. Several significant conclusions can be derived from the work described in this thesis: (1) Restoration is a highly specific template-directed process. The template is likely of ancestral origin, although the nature of the template and the precise mechanism of restoration remain unclear. (2) Restoration frequently gives rise to individuals that are genetic mosaics, a finding that cannot be attributed to outcrossing. (3) Restored sequences are more readily identified by molecular genotyping than phenotypic screening. Possible mechanisms and recommended future studies are discussed.

High-Speed Probe Card Analysis Using Real-time Machine Vision and Image Restoration Technique

Shin, Bonghun January 2013 (has links)
There has been an increase in demand for the wafer-level test techniques that evaluates the functionality and performance of the wafer chips before packaging them, since the trend of integrated circuits are getting more sophisticated and smaller in size. Throughout the wafer-level test, the semiconductor manufacturers are able to avoid the unnecessary packing cost and to provide early feedback on the overall status of the chip fabrication process. A probe card is a module of wafer-level tester, and can detect the defects of the chip by evaluating the electric characteristics of the integrated circuits(IC's). A probe card analyzer is popularly utilized to detect such a potential probe card failure which leads to increase in the unnecessary manufacture expense in the packing process. In this paper, a new probe card analysis strategy has been proposed. The main idea in conducting probe card analysis is to operate the vision-based inspection on-the- y while the camera is continuously moving. In doing so, the position measurement from the encoder is rstly synchronized with the image data that is captured by a controlled trigger signal under the real-time setting. Because capturing images from a moving camera creates blurring in the image, a simple deblurring technique has been employed to restore the original still images from blurred ones. The main ideas are demonstrated using an experimental test bed and a commercial probe card. The experimental test bed has been designed that comprises a micro machine vision system and a real-time controller, the con guration of the low cost experimental test bed is proposed. Compared to the existing stop-and-go approach, the proposed technique can substantially enhance the inspection speed without additional cost for major hardware change.

Restoration of Burns Bog : cumulative moisture deficit as an indicator of vegetation recovery and peat growth

Dilley, Laura 10 June 2014 (has links)
Burns Bog covers approximately 3,000 hectares between the Fraser River and Boundary Bay in Delta, BC. An ecologically unique ecosystem, its hydrology and ecology have been widely disturbed. Hydrology strongly shapes the character and distribution of vegetation and Sphagnum growth. This study investigated measures of hydrology, including water table residence times and cumulative moisture deficits, to quantify intuitive relationships between moisture stress and ecological zones. Regression analysis of quantitative field observations reveal statistically significant relationships between cumulative moisture deficits and several key bog plant species and Lodgepole pine (Pinus contorta) diameter at breast height, signifying that these relationships can be used to predict the potential for vegetation recovery. Sphagnum height measurements reveal the unexpected observation that most growth occurs during the cool moist winter and early spring. This study contributes to the hydrological management of Burns Bog and will help to guide the location and mechanisms of restoration efforts.

Finding our roots: ethnoecological restoration of lhasem (Fritillaria camschatcensis (L.) Ker-Gawl), an iconic plant food in the Squamish River Estuary, British Columbia.

Joseph, Leigh 28 August 2012 (has links)
Fritillaria camschatcensis L. Ker Gawl (Liliaceae), is a herbaceous flowering plant that grows in estuarine and subalpine habitats within its range from the northern limit in Alaska to its southern limit in western Oregon. This plant holds cultural significance in the Pacific Northwest as an important root vegetable that was cultivated in estuarine root gardens by many Indigenous Peoples. The bulbs of F. camschatcensis offered an important source of carbohydrates to a traditional diet that was high in protein, fats, oils and fibre. Lhásem is the Squamish name for F. camschatcensis, commonly known as northern riceroot, or chocolate lily. The Squamish Nation is very interested in restoring traditional plant foods into the community along with the traditional knowledge linked to them. Lhásem is a plant that many Squamish people were interested in learning about, thus it was an excellent candidate for ethnoecological restoration. Ethnoecological restoration brings cultural context, practices and technologies together with contemporary ecological restoration approaches and offers culturally relevant ways to restore a plant to the landscape. The east side of the Squamish Estuary, which borders the town of Squamish, has been impacted by a range of human-disturbances over the past century including: draining for agriculture, redirection of the Squamish River, dredging and the presence of industrial sites in close proximity to the estuary. All of these impacts have likely contributed to the decline of lhásem populations on the east side of the estuary. Through an ecological survey of the east and west sides of the Squamish Estuary I determined that the populations of F. camchatcensis are present and thriving on the west bank of the Squamish River. I collected vegetation and abiotic data and found that salinity is the most important abiotic factor affecting lhásem habitat. A logistic regression showed that salinity and the presence of lhásem are negatively correlated. Results of the vegetation data analysis indicated that Maianthemum dilatatum was an indicator for where lhásem is found growing on the west side of the Squamish Estuary and Aster subspicatus was the indicator for lhásem on the east. Lhásem restoration gardens were planted to explore the growth within one growing season across two restoration treatments, terrestrial sites and estuarine sites. The results indicate that terrestrial garden sites were more successful than estuarine garden sites and that whole bulbs were more successful than bulblets in the first year of growth. Through community interviews with elders, adults and youth, I documented the contemporary interests in the restoration of lhásem and found that the major interest of the community was focused on health, traditional food revitalization and knowledge renewal. I facilitated educational events in which Squamish Nation youth and community members learned about the plant and how to manage it in the Squamish Estuary gardens. Overall this research provides information for the future restoration of lhásem in the Squamish Estuary as well as a template to restore other culturally important plants. / Graduate
