Writing and the rights of reality: usurpation and potentiality in Derrida, Plato, Nietzsche, and Beckett
No full textThe thesis critically evaluates Jacques Derrida's conferral of the rights of reality on writing, focussing on his theory of an arche-text in light of the speculative nature of this theory. The theory is initially considered in the context of Derrida's elucidation of the usurpatory status of writing within the Platonic and Nietzschean texts. This consideration reveals an admission of writing's usurpatory status by both writers while at the same time demonstrating their awareness of the intrinsically speculative nature of this view, the significance of writing lying in its ability to exteriorise the radically indeterminate status of consciousness m relation to reality rather than its ability to displace consciousness or reality The analyses, therefore, not only bring the Derridean hypothesis of a repressive or phonocentric metaphysical episteme into question but also exhibit the historical and philosophical role of potentiality in relation to writing, writing's ultimate significance lying in its capacity to exteriorise our existence as a mode of potentiality. Accordingly, in the second half of the thesis the Derridean theory of writing is countered with a specifically Aristotelian theory of the text as it is exhibited in the prose of Samuel Beckett, an author whose significance lies in his close alignment with Derridean theory within contemporary criticism. It is demonstrated that this identification has obviated an awareness of the significance of potentiality within the Beckettian text, his work consequently being appraised in the previously neglected context of Aristotelian metaphysics

Ideographs, Fragments, and Strategic Absences: An Ideographic Analysis of <Collateral Damage>
No full textThis study examined the ideograph of through an analysis of the Bush Administration's rhetoric as well as visual photographs of Iraqi civilian deaths. The project argues that the psycho-dynamic rhetoric of the Bush Administration during a time of visual censorship lead to the dehumanization of Iraqi civilian deaths during the War in Iraq. The method consisted of a textual analysis of the Bush Administration's rhetoric and continued with a content analysis of news media's photographs. The author argues that critics gain a deeper understanding of the disappearing dead phenomenon of Iraqi civilians by examining ideographic fragments of psycho-dynamic rhetoric
A role for SUMO modification in transcriptional repression and activation
No full textSince the discovery of the SUMO (small ubiquitin-related modifier) family of proteins just over a decade ago, a plethora of substrates have been uncovered including many regulators of transcription. Conjugation of SUMO to target proteins has generally been considered as a repressive modification. However, there are now a growing number of examples where SUMOylation has been shown to activate transcription. Here, we discuss whether there is something intrinsically repressive about SUMOylation, or if the outcome of this modification in the context of transcription will prove to be largely substrate-dependent. We highlight some of the technical challenges that will be faced by attempting to answer this question

Booty Calls, Rage, and Racialized/sexualized Subjects: Tmz's Coverage of Rihanna and Chris Brown
No full textInternet-based celebrity gossip blog site, TMZ, is a growing cultural force. Employing critical rhetorical analytics, the author examines the TMZ coverage of Chris Brown's assault on his then-girlfriend, Rihanna. This project explicates TMZ's enthymematic invocation of dominant cultural ideologies surrounding race, sex, and domestic violence. Chapter 1 demonstrates the theoretical importance of both celebrities and gossip blogs, signaling the ideological importance of each. Chapter 2 critiques TMZ's reliance on historic myths regarding sex and race in their reporting on this case. Chapter 3 analyzes TMZ's humorous and affective strategies that bolster broader investments in colorblind ideologies. Chapter 4 concludes by examining the interplay of formal rhetorical elements that inform the project's findings. This research reveals that TMZ utilizes affective, enthymematic strategies that camouflage broader racist and sexist ideological impulses that perpetuate domestic violence myths
Avaliação em médio prazo da pressão intra-saco após correção endovascular de aneurisma de aorta abdominal com o uso de sensor sem fio
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Ciências Médicas.Justificativa: O objetivo do tratamento endovascular do aneurisma de aorta abdominal é a exclusão do saco aneurismático da circulação sistêmica. Para acompanhar a eficácia do tratamento é necessária a realização de angiotomografias seriadas. A monitorização continuada da pressão poderia diagnosticar precocemente casos em que esteja ocorrendo falha desse tratamento, auxiliando ou substituindo a tomografia. Objetivo: Avaliar a eficácia em médio prazo da medida de pressão através de sensor sem fio implantado no saco aneurismático após tratamento endovascular de aneurisma de aorta abdominal (AAA). Desenho do Estudo: Quarenta pacientes submetidos a tratamento endovascular de aneurisma de aorta abdominal receberam implante de sensor sem fio para monitorização em médio prazo da pressão intra-saco. Os dados foram analisados no primeiro, sexto, décimo segundo meses e anualmente. A cada análise, uma angiotomografia informava o diâmetro do aneurisma, presença e tipo de vazamento. A pressão arterial sistêmica assim como todos os dados pressóricos obtidos através do sensor foram coletados. Resultados: No seguimento, dos 40 sensores implantados apenas em dois o sinal não pode ser detectado. A pressão de pulso obtida apresentou boa sensibilidade em afastar a presença de vazamento quando inferior a 25mmHg no primeiro ano. Após esse período, o Índice de Endotensão mostra-se como a variável que mais se aproxima dos dados tomográficos. Na presença de vazamantos tipo I ou III, o sensor é capaz de identificar sucesso ou falha após a correção do vazamento. Até o segundo ano de seguimento, resultados apresentados pelo sensor são concordantes com dados tomográficos, a partir daí, perdem acurácia. Conclusão: Na amostra estudada não foi possível obter sensibilidade suficiente para substituir a realização da tomografia no acompanhamento dos AAA tratados por técnica endovascular. Um maior número de pacientes é necessário para estabelecer o verdadeiro papel da monitorização pressórica sem fio no seguimento do tratamento endovascular do aneurisma de aorta abdominal.Racional: The objective of endovascular treatment of an abdo-minal aortic aneurysm is to exclude the aneurysm sac from systemic circulation. In order to assess treatment effectiveness it is necessary to perform serial computed tomography (CT). Continued pressure moni-toring could provide an early diagnosis of cases in which this treatment is failing, helping or replacing CT. Objective: Evaluation of medium-term effectiveness of pressure measurement using a wireless sensor implanted in the aneurysm sac after endovascular treatment of abdominal aortic aneurysm. Method: Forty patients undergoing endovascular treatment for abdominal aortic aneurysm had a wireless sensor implanted for medium-term monitoring of intrasac pressure. The data were analyzed in the first, sixth and twelfth month and annually. At each analysis, a CT scan in-formed the aneurysm diameter, presence and risk of endoleaks. System-ic arterial pressure was collected, as well as all pressure data obtained through the sensor. Results: Of the 40 sensors implanted, the signal could not be de-tected only in two. The pulse pressure obtained presented good sensitivi-ty to rule out the presence of leakage when it was less than 25mmHg during the first year. After this period, the Endotension Index is the variable that comes closest to the CT scan data. With type I or III endo-leaks, the sensor can identify success or failure after endoleak repair. Until the second year of follow up, the results presented by the sensor agree with CT data, and then become less accurate. Conclusions: In the sample studied sufficient sensitivity could not be achieved to replace the CT when following AAA treated by the en-dovascular technique. A larger number of patients is needed to deter-mine the true role of wireless pressure monitoring when following en-dovascular treatment of abdominal aortic aneurysm
Implementasi Penggunaan Algoritma Branch and Bound terhadap Penyelesaian Masalah Optimisi Multi-Travelling Salesman Problem (M-TSP)
No full textMulti-Travelling Salesman Problem is the next generation of problem Travelling
Salesman Problem (TSP), which is the issue of TSP by the number of salesman
that more than one person. The purpose of the Multi-Travelling Salesman
Problem is to determine the shortest route every salesman so that the costs used in
the course can be minimum. In this case the first step on the author to resolve the
M-TSP is to form a tour every salesman based heuristic method assignment.
Through the establishment of the sub tour then there are some vertices do not need
to be traversed by a salesman. In other words, the process of forming a reduction
vertex sub tour. Shape sub tour will be converted into a distance matrix (Cost
Matrix) further optimized by using the branch and bound. Branch and bound
algorithm is an algorithm that is effective enough to resolve the problems and
optimize M-TSP. The resulting solution is minimum trajectory and amount of fees
during the trip. In case the author concludes that the issue M-TSP is not included
in the complete graph. This is because in the optimization of deviations between
vertices that are being optimized.Multi-Travelling Salesman Problem merupakan generasi dari persoalan Travelling
Salesman Problem (TSP) , yaitu persoalan TSP dengan jumlah salesman yang
lebih dari satu orang. Tujuan dari Multi-Travelling Salesman Problem adalah
menentukan rute terpendek setiap salesman sehingga biaya yang digunakan dalam
perjalanan dapat minimum. Dalam hal ini langkah awal yang dilakukan penulis
untuk menyelesaikan masalah M-TSP adalah dengan membentuk tour setiap
salesman berdasarkan metode heuristic assignment. Melalui pembentukan sub
tour tersebut maka ada beberapa vertex yang tidak perlu dilalui oleh salesman.
Dengan kata lain pada proses pembentukan sub tour terjadi pengurangan vertex.
Bentuk sub tour akan diubah ke dalam bentuk matriks jarak (Cost Matrix)
selanjutnya dioptimasikan dengan menggunakan branch and bound. Algoritma
branch and bound merupakan salah satu algoritma yang cukup efektif untuk
menyelesaikan dan mengoptimasikan masalah M-TSP.75 HalamanSkripsi Sarjan
Uncertainty and the Disappearance of International Credit
No full textWe show that increased uncertainty about the size of an emerging market's external debt has a nonlinear and potentially large adverse effect on the supply of international credit offered to them. We also show that if international creditors are first- order risk averse, attaching greater weight to utility derived from bad outcomes than from good ones, a moderate increase in uncertainty about debt overhang or about other relevant factors affecting repayment prospects-- can cause the supply of credit to dry up completely. We therefore offer one possible explanation for why emerging markets may find themselves suddenly cut off from international capital markets.
Six-proposition manifesto for small Island territories
No full textConventional wisdom suggests that small, often island, states are more likely than larger nations to be hard hit by the effects of national disasters, of fluctuations in the global economy, and the political aspirations of world powers. The structural weaknesses they share have been quantified to create a Vulnerability Index. This paper points to what the author sees as flaws in the concept of vulnerability and its application to the weaknesses of small states. In particular he presents evidence that small developing countries have performed no worse than larger countries. He sets out six propositions which explain this paradox and identifies the comparative advantages that small states hold.peer-reviewe
Experimental data of cathodes manufactured in a convective dryer at the pilot-plant scale, and charge and discharge capacities of half-coin lithium-ion cells.
No full textMegtec Systems pilot-plant scale continuous convective coater. The data was generated as part of an experimental design involving the following coating-drying process variables and ranges: comma bar gap, 80-140 µm; web speed, 0.5-1.5 m/min; coating ratio, 110-150%; drying temperature, 85-110 °C and drying air speed, 5-15 m/s. The manufacturing data include pre-calendered coating thickness, mass loading dry and wet, pre-calendered porosity, spatial autocorrelation and join counting (SAJC) -score for carbon and for fluorine, cell thickness, coating weight and porosity of 15 different electrode coatings and 45 half-coin cells. The electrochemical data was obtained at 25 °C in a Maccor 4000 series battery cycler and consists of charge and discharge capacities at C/20, C/5, C/2, 1C, 2C, 5C and 10C C-rates. Discharge gravimetric and volumetric capacities, rate performance (at 5C:0.2C) and first cycle loss data is also reported. Details of the experimental design and a comprehensive analysis of the data can be found in the co-submitted manuscript (Román-Ramírez et al., 2021). Additional collected data not used in Román-Ramírez et al. (2021) is reported in the present manuscript and include visual observations of coating defects, rheological properties of the electrode slurries (solid content, viscosity, coating shear rate and viscosity at coating shear rate), room temperature and room humidity during the coatings and first cycle loss of the coin cells. Raw and analyzed data is made available. The reported data can be used to extend the analysis reported in Román-Ramírez et al. (2021), and for the comparison of relevant data obtained at different manufacturing scales. [Abstract copyright: © 2021 The Author(s). Published by Elsevier Inc.
