The struggle for protection of environmental refugees: who's responsibility? Discourses from the United Nations and Non-governmental organizations

This thesis identifies, examines and problematizes some of the discourses that have so far come to light on the issue of protection for environmental refugees. By analyzing the discourses produced by the United Nations Office of the High Commissioner for Refugees (UNHCR) and two non-governmental organizations - the Environmental Justice Foundation (EJF) and Equity and Justice Working Group Bangladesh (EquityBD), I examine the struggling discourses that have emerged about how protection for environmental refugees has been interpreted. To do this, I rely on Ernesto Laclau and Chantal Mouffe's theory and method of discourse analysis. The results show that responsibilization is the main point of struggle in the discussions on the protection of environmental refugees. As a floating signifier, it was utilized by the discourses produced by the UNCHR and the selected NGOs in contingent ways and with different political objectives. The UNHCR discourse responsibilized both the environmental refugees for their own protection and the individual states. The EJF and EquityBD, by contrast, allocated responsibility for the protection of environmental refugees to the international community. These contingent understandings of responsibilization necessitated different justifications. While the EJF discourse relied on humanitarianism for the assistance of environmental refugees, the EquityBD discourse constructed a rights based, more permanent solution. The humanitarian based discourse of the EJF was found to be inextricably linked with the neoliberal discourse produced by the UNHCR. Both these discourses encouraged environmental refugees to stay in their homelands, undermining the politics of protection. Another way in which protection was undermined was by UNHCR's discourse on securitization. In this context, climate change induced displacement became threat to developed countries, the global economy and transnational classes. The struggling discourses about who/what has been allocated responsibility for the protection of environmental refugees also meant that identities of the displaced be constructed in specific ways. While the UNHCR discourse constructed as voluntary migrants and predators, the EJF and EquityBD discourses portrayed them as victims. However, even though the EJF discourse constructed them as victims, their reliance on humanitarianism could also be interpreted as a way of giving the environmental refugee a predator like identity. These discourses on responsibilization and identity formation clashed with each other in the aim of achieving a hegemonic position in discussions and debates about the protection of environmental refugees.

Poetics of the Nameless Middle : Japan and the West in Philosophy and Music of the Twentieth Century

This study investigates the affinities between philosophy, aesthetics, and music of Japan and the West. The research is based on the structuralist notion (specifically, on that found in the narratology of Algirdas Julius Greimas), that the universal grammar functions as an abstract principle, underlying all kinds of discourse. The study thus aims to demonstrate how this grammar is manifested in philosophical, aesthetic, and musical texts and how the semiotic homogeneity of these texts can be explained on this basis. Totality and belongingness are the key philosophical concepts presented herein. As distinct from logocentrism manifested as substantializations of the world of ideas , god or mind, which was characteristic of previous Western paradigms, totality was defined as the coexistence of opposites. Thus Heidegger, Merleau-Ponty, Dōgen, and Nishida often illustrated it by identifying fundamental polarities, such as being and nothing, seer and seen, truth and illusion, etc. Accordingly, totality was schematically presented as an all-encompassing middle of the semiotic square. Similar values can be found in aesthetics and arts. Instead of dialectic syntagms, differentiated unity is considered as paradigmatic and the study demonstrates how this is manifested in traditional Japanese and Heideggerian aesthetics, as well as in the aspects of music of Claude Debussy and Tōru Takemitsu.

Effect of leachate recirculation and extent of degradation on the stability of bioreactor landfill slopes

The stability of a bioreactor landfill slope is influenced by the quantity and method of leachate recirculation as well as on the degree of decomposition. Other factors include properties variation of waste material and geometrical configurations, i.e., height and slope of landfills. Conventionally, the stability of slopes is evaluated using factor of safety approach, in which the variability in the engineering properties of MSW is not considered directly and stability issues are resolved from past experiences and good engineering judgments. On the other hand, probabilistic approach considers variability in mathematical framework and provides stability in a rational manner that helps in decision making. The objective of the present study is to perform a parametric study on the stability of a bioreactor landfill slope in probabilistic framework considering important influencing factors, such as, variation in MSW properties, amount of leachate recirculation, and age of degradation, in a systematic manner. The results are discussed in the light of existing relevant regulations, design and operation issues.

Patch-based and multiresolution optimum bilateral filters for denoising images corrupted by Gaussian noise

We propose optimal bilateral filtering techniques for Gaussian noise suppression in images. To achieve maximum denoising performance via optimal filter parameter selection, we adopt Stein's unbiased risk estimate (SURE)-an unbiased estimate of the mean-squared error (MSE). Unlike MSE, SURE is independent of the ground truth and can be used in practical scenarios where the ground truth is unavailable. In our recent work, we derived SURE expressions in the context of the bilateral filter and proposed SURE-optimal bilateral filter (SOBF). We selected the optimal parameters of SOBF using the SURE criterion. To further improve the denoising performance of SOBF, we propose variants of SOBF, namely, SURE-optimal multiresolution bilateral filter (SMBF), which involves optimal bilateral filtering in a wavelet framework, and SURE-optimal patch-based bilateral filter (SPBF), where the bilateral filter parameters are optimized on small image patches. Using SURE guarantees automated parameter selection. The multiresolution and localized denoising in SMBF and SPBF, respectively, yield superior denoising performance when compared with the globally optimal SOBF. Experimental validations and comparisons show that the proposed denoisers perform on par with some state-of-the-art denoising techniques. (C) 2015 SPIE and IS&T

Theory and Application of the Transient Injection Well Test

Based on the theory of the pumping well test, the transient injection well test was suggested in this paper. The design method and the scope of application are discussed in detail. The mathematical models are developed for the short-time and long-time transient injection test respectively. A double logarithm type curve matching method was introduced for analyzing the field transient injection test data. A set of methods for the transient injection test design, experiment performance and data analysis were established. Some field tests were analyzed, and the results show that the test model and method are suitable for the transient injection test and can be used to deal with the real engineering problems.

Por qué es necesario un método en la decisión bioética

Resumen: Las resoluciones de un comité de Bioética influyen directamente en la vida de las personas pero son superadoras de la instancia particular. Tal vez por causa de su misma importancia social, el debate bioético contemporáneo se ha escapado del dominio de los especialistas y ha llegado a comprometer y apasionar al público en general. Éste intuye que en esa discusión se juega la sociabilidad humana y aun la misma noción de Hombre. La sola reunión del comité experto no procura una respuesta. Para el comité de Bioética, la verdad no es evidente a primera vista, sino que debe descubrirla. Para ello es necesario el método para seguir tras la verdad de las cosas y, aunque nada asegura la infalibilidad, contribuye a evitar errores morales.

Deepwater reef fishes and multibeam bathymetry of the Tortugas South Ecological Reserve, Florida Keys National Marine Sanctuary, Florida

The Tortugas South Ecological Reserve, located along the margin of the southwest Florida carbonate platform, is part of the largest no-take marine reserve in the U.S. Established in July 2001, the reserve is approximately 206 km2 in area, and ranges in depths from 30 m at Riley’s Hump to over 600 m at the southern edge of the reserve. Geological and biological information for the Tortugas South Reserve is lacking, and critical for management of the area. Bathymetric surveys were conducted with a Simrad EM 3000 multibeam echosounder at Riley’s Hump and Miller’s Ledge, located in the northern and central part of the reserve. Resulting data were used to produce basemaps to obtain geological ground truth and visual surveys of biological communities, including reef fishes. Visual surveys were conducted using SCUBA and the Phantom S2 Remotely Operated Vehicle (ROV) at Riley’s Hump. Visual surveys were conducted using the ROV and the Deepworker 2000 research submersible along Miller’s Ledge, within and outside of the reserve. A total of 108 fishes were recorded during SCUBA, ROV, and submersible observations. Replicate survey transects resulted in over 50 fishes documented at Miller’s Ledge, and eight of the top ten most abundant species were planktivores. Many species of groupers, including scamp (Mycteroperca phenax), red grouper (Epinephelus morio), snowy grouper (E. niveatus), speckled hind (E. drummondhayi), and Warsaw grouper (E. nigritus), are present in the sanctuary. Numerous aggregations of scamp and a bicolor phase of the Warsaw grouper were observed, indicating the importance of Miller’s Ledge as a potential spawning location for both commercially important and rare deep reef species, and as a potential source of larval recruits for the Florida Keys and other deep reef ecosystems of Florida

A psicologia social e a noção de verdade: do conhecimento do erro à feitura de tramas

Este estudo visa compreender a relação que a psicologia social estabelece com a noção de verdade e de que modo este conceito foi fundamental na aquisição de seu estatuto científico. Tomando como ponto de partida a análise semântica do termo, principalmente a partir do seu paradigma grego (alétheia), a análise teórica se subdivide em três eixos principais. O primeiro deles irá abordar a tensão que se estabelece acerca das exigências do conhecimento entre o movimento sofístico e o modelo platônico. Num segundo momento, serão analisadas as torções promovidas pelas ciências modernas, transformando o método científico e racional num instrumento de classificação de todos os erros. Na parte final, o foco se desloca para as especificidades da psicologia social, buscando apontar um contraste entre as pesquisas de W. Wundt (1832-1920) e sua influência nas experiências clássicas da psicologia experimental e no empirismo radical de W. James (1842-1910). O pensamento de James será analisado dando ênfase à influência indeterminista presente nas suas propostas filosóficas e psicológicas e à análise de uma de suas principais contribuições: a teoria da verdade.

Report on the analysis of salmon scale samples returned by anglers on the Rivers Ribble and Hodder

Fisheries technical staff from the North West Central Area of the National Rivers Authority (NRA) currently provide a service for the ageing of salmon scales from fish caught by anglers on the Rivers Ribble and Hodder in order to gather information on the biological characteristics of the salmon population on the River Ribble system in terms of weight, freshwater age and sea age. At the beginning of each fishing season, scale envelopes are distributed by the NRA to angling clubs and some individual anglers. Scales taken from salmon caught on the rivers are returned to the NRA Central Area Office by the anglers, or more often, by NRA bailiffs. The age of each fish caught is then determined by the identification and counting of annuli for both the river and sea zones on the scale. Information is provided by the angler on the scale packet concerning the length and weight of the fish caught, and the date, location and method of capture. Both this information and the age of the fish is recorded on a database. These data can be used to investigate the distribution, and exploitation patterns of the different age classes of the salmon stock within the river system. This report is principally concerned with the scale samples received in 1994, although comparison is also made with samples from 1993 and 1992. References to data will all relate to that received in 1994 unless an alternate year is stated.

BAYESIAN MODEL SEARCH AND MULTILEVEL INFERENCE FOR SNP ASSOCIATION STUDIES.

Technological advances in genotyping have given rise to hypothesis-based association studies of increasing scope. As a result, the scientific hypotheses addressed by these studies have become more complex and more difficult to address using existing analytic methodologies. Obstacles to analysis include inference in the face of multiple comparisons, complications arising from correlations among the SNPs (single nucleotide polymorphisms), choice of their genetic parametrization and missing data. In this paper we present an efficient Bayesian model search strategy that searches over the space of genetic markers and their genetic parametrization. The resulting method for Multilevel Inference of SNP Associations, MISA, allows computation of multilevel posterior probabilities and Bayes factors at the global, gene and SNP level, with the prior distribution on SNP inclusion in the model providing an intrinsic multiplicity correction. We use simulated data sets to characterize MISA's statistical power, and show that MISA has higher power to detect association than standard procedures. Using data from the North Carolina Ovarian Cancer Study (NCOCS), MISA identifies variants that were not identified by standard methods and have been externally "validated" in independent studies. We examine sensitivity of the NCOCS results to prior choice and method for imputing missing data. MISA is available in an R package on CRAN.

Bystander Narratives: The Fiction of J.M. Coetzee and the Holocaust

J.M. Coetzee’s novels are suffused with a pervasive, though often oblique, Holocaust awareness. Direct references to the event and to the historical era to which it belongs, subtle stylistic and thematic echoes of Holocaust writing, and the recurrent mobilization of Holocaust imagery in Coetzee’s novels all contribute to suggest the significance of the event to the author’s work and thought. Providing Coetzee with a lens through which to view the contemporary situation, both local and global, the Holocaust offers Coetzee a means by which difficult and complex questions of ethics and historiographical truth may be approached. Above all, the Holocaust and its representation contribute to Coetzee’s exploration of the dilemmas of translating the traumatic lived experience of atrocity – including, but not limited to, life in apartheid South Africa – into narrative form. Taken as a whole, Coetzee’s oeuvre initially anticipates and later responds to, in characteristically oblique fashion, the narrative project(s) facing post-apartheid South Africa as the newly-democratic nation sought to make sense of its past through a variety of means, the most important of which was the country’s Truth and Reconciliation Commission. Implicitly challenging the TRC’s findings as well as its narrative assumptions, the Coetzean oeuvre accordingly invites being read as offering a continuous and evolving counter-narrative to the TRC and its construction of a narrative of the apartheid past for the post-apartheid nation. In utilizing the Holocaust, its representations, and the reception thereof to frame his response to apartheid, Coetzee implicates both in a critique of the Western model of modernity, suggesting, in the process, the importance of reconfiguring modernity in a more ethical shape.

Optimising the use of virtual and conventional simulation: a clinical and economic analysis

Background and purpose: Currently, optimal use of virtual simulation for all treatment sites is not entirely clear. This study presents data to identify specific patient groups for whom conventional simulation may be completely eliminated and replaced by virtual simulation. Sampling and method: Two hundred and sixty patients were recruited from four treatment sites (head and neck, breast, pelvis, and thorax). Patients were randomly assigned to be treated using the usual treatment process involving conventional simulation, or a treatment process differing only in the replacement of conventional plan verification with virtual verification. Data were collected on set-up accuracy at verification, and the number of unsatisfactory verifications requiring a return to the conventional simulator. A micro-economic costing analysis was also undertaken, whereby data for each treatment process episode were also collected: number and grade of staff present, and the time for each treatment episode. Results: The study shows no statistically significant difference in the number of returns to the conventional simulator for each site and study arm. Image registration data show similar quality of verification for each study arm. The micro-costing data show no statistical difference between the virtual and conventional simulation processes. Conclusions: At our institution, virtual simulation including virtual verification for the sites investigated presents no disadvantage compared to conventional simulation.

Hillsborough: The Truth

Hillsborough: The Truth was first published in 1999 to universal acclaim. Established as the definitive, unique account of the disaster, in which 96 men, women and children died, hundreds were injured and thousands traumatised, it details the appalling treatment endured by the bereaved and survivors in the immediate aftermath and the inhumanity of the identification process. It reveals the inadequacies of the police investigations, official inquiries and inquests, uncovering the systematic review and alteration of South Yorkshire police statements conducted with the approval of police investigators and Lord Justice Taylor’s inquiry. It examines in depth the subsequent private prosecution and trial of two senior police officers in 2000. Using verbatim accounts, Scraton's detailed analysis demonstrates the inadequacy of legal processes and the remarkable breadth of judicial discretion, undermining and inhibiting such cases.

Powerful, disturbing and harrowing, Hillsborough: The Truth exposes the institutional complacency that made a tragedy on this scale inevitable. It shows the law’s failure to provide appropriate means of access, disclosure and redress for those facing the consequences of institutional neglect and personal negligence. And it tells how ordinary people suffer when those in authority sacrifice truth and accountability to protect their reputations. In this new edition Scraton reflects critically on two decades of policy and legal reform including crowd safety and inquest procedure and on the continuing struggles of the bereaved and survivors who have campaigned relentlessly for truth, acknowledgment and justice.

Incorporation of multiwalled carbon nanotubes to acrylic based bone cements: Effects on mechanical and thermal properties

Polymethyl methacrylate (PMMA) bone cement–multiwalled carbon nanotube (MWCNT) nanocomposites with a weight loading of 0.1% were prepared using 3 different methods of MWCNT incorporation. The mechanical and thermal properties of the resultant nanocomposite cements were characterised in accordance with the international standard for acrylic resin cements. The mechanical properties of the resultant nanocomposite cements were influenced by the type of MWCNT and method of incorporation used. The exothermic polymerisation reaction for the PMMA bone cement was significantly reduced when thermally conductive functionalised MWCNTs were added. This reduction in exotherm translated in a decrease in thermal necrosis index value of the respective nanocomposite cements, which potentially could reduce the hyperthermia experienced in vivo. The morphology and degree of dispersion of the MWCNTs in the PMMA matrix at different scales were analysed using scanning electron microscopy. Improvements in mechanical properties were attributed to the MWCNTs arresting/retarding crack propagation through the cement by providing a bridging effect into the wake of the crack, normal to the direction of crack growth. MWCNT agglomerations were evident within the cement microstructure, the degree of these agglomerations was dependent on the method used to incorporate the MWCNTs into the cement.
