An Ear for an Eye: Greek Tragedy on Radio examines the dramaturgical principles involved in the adaptation of Greek tragedies for production as radio dramas by considering the classical dramatic form’s representational ability through purely oral means and the effects of dramaturgical interventions. The inherent orality of these tragedies and Aristotle’s suggested limitation of spectacle (opsis) appears to make them eminently suitable for radio, a medium in which the visual dimension of plays is relegated entirely to the imagination through the agency of sound. Utilizing productions from Canadian and British national radio (where classical adaptations are both culturally mandated and technically practical) from the height of radio’s golden age to the present, this study demonstrates how producers adapted to the unique formal properties of radio. The appendices include annotated, chronological lists of 154 CBC and BBC productions that were identified in the course of research, providing a significant resource for future investigators. The dissertation first examines the proximate forces which shaped radio dramaturgy and radio listeners. Situating the emergence of radio in the context of modernity, Chapter One elucidates how audiences responded to radio’s return to orality within a visually-oriented culture. Chapter Two then analyses the specific perceptual and imaginative activity of individuals, considering how audiences experience acoustic space. I describe how the audience’s central position in the reception of radio drama is integral to the completion of the dramatic frame of radio. The second part of this dissertation addresses radiophonic dramaturgy and issues in representation. In Chapter Three, the didactic and nationalistic impetus for the adaptation of classics as radio plays is considered and the principles of radio adaptation are outlined. The final two chapters examine the formal properties of productions in adaptation through case studies to illustrate where the play’s inherent orality allows for ease in adaptation or where greater dramaturgical intervention is required. Chapter Four examines the construction of dramatic figures, music and song, the use of paratheatrical materials, and narrative strategies for the representation of action, space, and time. Chapter Five examines productions where greater dramaturgical intervention and innovation is in evidence, including the manipulation of perspective (in the CBC’s 2001 Medea), the use of music to modernize setting (in the 1998 CBC-BBC co-production of The Trojan Women), the use of experimental montage (in the BBC’s 1976 Ag), the introduction of flashback sequences (in the CBC’s 1987 Antigone), and solutions to the problem of what I term “dramaturgical erasure” (the inadvertent removal of silent figures from the perspectival field).

The use of sedation protocols can assist in obtaining samples, but it is not known whether there are changes in haematological values and hemostasis. The aim of this study was to evaluate the parameters of the CBC, primary and secondary hemostasis of domestic cats under physical restraint and under different protocols of sedation. 50 cats were used from private owners, aged between one and seven years and with 3.32 Kg weight. The animals were randomly divided into two groups according to the association of drugs used: DB Group (25) dexmedetomidine (5 &#956;g/kg) and butorphanol (0.3 mg/kg); DBC Group (25) dexmedetomidine (5 &#956;g/kg), butorphanol (0.3 mg/kg) and ketamine (3 mg/kg), and all applications made by intramuscular injection. Blood samples were collected by jugular vein puncture in two moments, animals under physical restraint, and after applying one of the protocols of sedation. Scales were used to assess acute stress (zero to three) and evaluation of sedation (one to four). The parameters evaluated in two moments were the red cell count, hemoglobin, hematocrit, dosage globular volume (MCV), mean corpuscular hemoglobin concentration (CHGM), measurement of total plasma protein, platelet count, total and differential leukocyte count, clotting time, prothrombin time (PT) and activated partial thromboplastin time (Aptt), Thrombin time (TT). The bleeding time of the oral mucosa (TSMO) was carried out only after the use of sedation. The latent period was also measured. The results were evaluated by Sigma Plot computer program for Windows (2009), by applying the test of analysis of variance (ANOVA), and the observed differences were analyzed by Tukey test (p < 0.05). The values found for erythrocytes, hemoglobin, hematocrit, MCV, CHGM, platelets and leukocytes showed no statistical difference between the physical restraint and after the use of the sedation protocol or between sedation protocols. The coagulation time values showed no difference between moments and groups. The oral mucosal bleeding time showed no difference between the groups. Already the TP, APTT and TT values were different between groups, without difference between times. The stress evaluation showed that there was a predominance of animals with no stress or discreet stress during physical restraint. Sedation evaluation showed that the protocol used in DBC was more effective in relation to the DB group. As there were no clinically relevant changes in the values obtained under physical restraint and after the use of protocols, it is suggested that the use of these protocols of sedation does not interfere in the values of primary and secondary hemostasis and blood in healthy cats / A colheita de amostras de sangue não deve ter influência de fatores que interfiram nos resultados, porém essa situação nem sempre é possível, sobretudo nos felídeos. O uso de protocolos de sedação pode auxiliar na obtenção de amostras, porém não se sabe se há alteração nos valores hematológicos e de hemostasia. O objetivo deste trabalho foi avaliar os parâmetros do hemograma, hemostasia primária e secundária de felinos domésticos sob contenção física e sob diferentes protocolos de sedação. Foram utilizados 50 gatos provenientes de proprietários particulares, com idade entre um e sete anos e com peso de 3,32 Kg. Os animais foram divididos aleatoriamente em dois grupos de acordo com a associação de drogas utilizadas: Grupo DB (25 animais) dexmedetomidina (5&#956;g/kg) e butorfanol (0,3 mg/kg); Grupo DBC (25 animais) dexmedetomidina (5&#956;g/kg), butorfanol (0,3 mg/kg) e cetamina (3mg/kg), sendo todas as aplicações realizadas pela via intramuscular. As amostras de sangue foram colhidas por punção da veia jugular em dois momentos, animais sob contenção física, e após a aplicação de um dos protocolos de sedação. Foram utilizadas escalas para avaliação do estresse agudo (zero a três) e para avaliação da sedação (um a quatro). Os parâmetros avaliados nos dois momentos foram contagem de eritrócitos, dosagem de hemoglobina, hematócrito, volume globular médio (VGM), concentração de hemoglobina globular média (CHGM), mensuração da proteína plasmática total, contagem de plaquetas, contagem total e diferencial de leucócitos, além do tempo de coagulação, tempo de protrombina (TP), tempo de tromboplastina parcial ativada (TTPa) e tempo de trombina (TT). O tempo de sangramento da mucosa oral (TSMO) foi realizado somente após o uso de sedação. O período de latência também foi mensurado. Os resultados foram avaliados por programa computacional Sigma Plot for Windows (2009), aplicando-se o teste de análise de variância (ANOVA), sendo que as diferenças observadas foram analisadas pelo teste de Tukey (p<0,05). Os valores encontrados para eritrócitos, hemoglobina, hematócrito, VGM, CHGM, plaquetas e leucócitos, não apresentaram diferença estatística entre o momento contenção física e após o uso do protocolo de sedação, ou entre os protocolos de sedação. Os valores de tempo de coagulação não demonstraram diferença entre momentos e grupos. O tempo de sangramento da mucosa oral não apresentou diferença entre os grupos. Já o TP, TTPa e TT se mostraram diferentes entre grupos, sem diferenças entre momentos. A avaliação do estresse demonstrou que houve predomínio de animais com ausência de estresse ou estresse discreto durante a contenção física. A avaliação da sedação demonstrou que o protocolo utilizado no grupo DBC foi mais efetivo em relação ao grupo DB. Como não foram observadas alterações relevantes clinicamente nos valores obtidos sob contenção física e após a utilização dos protocolos, sugere-se que a utilização desses protocolos de sedação não interfere nos valores de hemograma e hemostasia primária e secundária em gatos saudáveis

This study examines the efficacy of the Canadian Memory Fund to advantage the use of digital archives for the purposes of developing historical consciousness in Canadian students and life-long learners. The perceived significance of digital archives to this end is reflected in the launch of the Department of Canadian Heritage’s (PCH) Canadian Culture Online Program (CCOP) in 2000. Employing a qualitative research design, this study examines how PCH defined the challenges to Canadians’ historical memory, and conceived of a technological solution to this inherently cultural and educational challenge. Using a case study, the strategies deployed by the CBC and Radio-Canada digital archives units, funded recipients of the CMF, to achieve the intended goals of the CCOP, and whether the resulting websites meet the technical criteria for the study of historical consciousness, are examined.

Indigenous autonomy, self-government and self-determination have historically been an area of conflict within the settler colonial state of Canada. This thesis aims to analyze critically the Canadian state’s alleged progressive nature in regard to nation-to-nation relations as well as the discourses that portray Canadian society as fostering Indigenous rights. Grounded in previous research and contextual background, this study uses the Discourse Historical Approach (DHA) to investigate how Canadian media produces and reproduces discourse around the issues connected with Indigenous resistance since the ‘Oka Crisis’ of 1990, based on the selected material published by The Canadian Broadcasting Corporation. The findings illustrate that while liberal-influenced narratives have improved, significant identification of decolonization within Canada’s media was not found and the structures of settler colonialism remain largely unchanged.

The brown marmorated stink bug (BMSB), Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an invasive phytophagous species native to eastern Asia. Due to its wide host plant range, it is considered among the most harmful agricultural pests in the invaded areas, including Europe, North and South America. In addition to its impact on crops, this insect causes a nuisance in urban areas, by invading buildings for overwintering using their aggregation pheromones and emitting an unpleasant smell when disturbed. The current management of this species is mainly based on the use of chemical insecticides, which show efficacy when applied frequently, with consequent negative impact on beneficial insects in the agroecosystems. As a result, there is a desire for more environmentally friendly solutions for the management of BMSB. A valid alternative is the use of exotic and coevolved biocontrol agents, for instance, the Samurai wasp, Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae), which is already showing promising medium and long-term results against BMSB in classical biocontrol projects. Within the frame of the least-toxic alternatives, the use of the Sterile Insect Technique (SIT) in an Area-Wide management approach is potentially a valid strategy to be included in integrated control and eradication programs. The main objective of this research, therefore, was to develop a SIT for potential use in the eradication of BMSB in newly introduced areas and/or as an additional tool to reduce its impact in areas where invasive populations have been already established. However, the effective use of SIT requires producing a high number of insects, and mass rearing for such a species is considered too complicated and expensive. To overcome this limitation, we evaluated a harvest, irradiation, and release strategy using wild overwintering adults. New live traps baited with high-load pheromones have been developed for mass trapping, exploiting the natural phenomenon ruled behaviour of aggregation of BMSB in preparation for overwintering. The captures of the new pheromone traps were compared with those of identically baited sticky panels through daily services lasting 2 weeks. Following winter diapause, the collected males were irradiated with high-energy photons at four different dosages: 16, 24, 32 and 40 Gy. The effects of irradiation on the biology i.e., fertility, longevity, and mating behaviour of overwintering BMSB males were evaluated with respect to unirradiated males. To encourage the use of SIT, a linear accelerator from a hospital facility was used for irradiation instead of the classical method involving radioactive materials. A second control 0 Gy was adopted to evaluate the possible negative effects on the biology (longevity, fertility, and fecundity) of insects due to the preparation for the irradiation. Moreover, as part of an integrated pest management (IPM) strategy, the combined use of the egg parasitoid T. japonicus and SIT was considered. The suitability of sterile eggs as oviposition substrate for T. japonicus was evaluated by comparing irradiated BMSB eggs at 40 Gy, eggs obtained by fertile female mated with sterile males irradiated at 50 Gy, and refrigerated sterile eggs currently used for laboratory rearing and field monitoring. The results of the research are encouraging for SIT applications in IPM approach. 1) The new traps caught up to 15-times more adult BMSB than the sticky panels in the two weeks of collections. 2) The developed irradiation protocol that involved a 6 MV medical linear accelerator has allowed the achievement of a high level of sterility of overwintering males (over 95%) already at 32 Gy without compromising males’ longevity and mating behaviour (in no-choice conditions). No adverse effects due to the irradiation preparation protocol were observed. 3) Sterile eggs obtained by mating sterile irradiated males and fertile females (SIT eggs), showed a higher parasitoid emergence rate (%) than both those directly irradiated and refrigerated. The difference in the emergence rate is even more evident when the eggs are 20 days old, with a parasitoid emergence rate of (75.56 %) for SIT eggs compared to those irradiated (44.68 %) and refrigerated (37.57%). In conclusion: 1) the new live traps are effective in mass trapping, 2) wild harvested males of BMSB can be used in SIT, 3) the use of linear accelerators for irradiation of BMSB is a feasible alternative to classical radioactive sources and 4) sterile eggs obtained by mating sterile males and fertile females are a valid substrate for T. japonicus oviposition, supporting the potential use of SIT on BMSB.

The life of RNA polymerase II (RNAPII) transcripts is shaped by the dynamic formation of mutually exclusive ribonucleoprotein complexes (RNPs) that direct transcript biogenesis and turnover. A key regulator of RNA metabolism in the nucleus is the scaffold protein ARS2 (arsenic resistance protein 2), that binds to the cap binding complex (CBC) and regulates processing, degradation, and export of RNAPII transcripts. We report here that alternative splicing of ARS2’s intron 5, generates cytoplasmic isoforms that lack 270 amino acids from the N-terminal of the protein and are functionally distinct from nuclear ARS2. ARS2 isoforms distinctive roles are evidenced under physiological conditions and stress. Under physiological conditions, ARS2 isoforms differentially regulate transcript degradation through nonsense mediated decay (NMD). Switching of ARS2 isoforms within the CBC in the cytoplasm has dramatic functional consequences, changing ARS2 from a NMD inhibitor to a NMD promoter that enhances the binding of UPF1 to CBP80 and ERF1, favouring SURF complex formation, SMG7 recruitment and transcript degradation. ARS2 isoform exchange is also relevant during arsenic stress. Cytoplasmic ARS2 is specifically induced during arsenic exposure. It is crucial for arsenic sensitivity, and promotes a global response to arsenic in a CBC independent manner. We propose that ARS2 isoform switching promotes the proper recruitment of RNP complexes during NMD and the cellular response to arsenic stress. The existence of non-redundant ARS2 isoforms is relevant for cell homeostasis, stress response and cancer treatment. / Graduate / 2023-04-14

<p>The purpose of this study has been to examine how customers, by interacting with each other, can communicate and create the image of a brand. We find this topic to be relevant since there are no previous studies conducted concerning the customers influence on the brand image. Our ambition has been to describe in what ways and to what extent the customer can affect and influence the brand image by communicating with other customers. To fulfill our purposed we have targeted three important questions which are:</p><p>• In which ways can the customer affect the communicated image of a brand?</p><p>• To what extent can the customer influence the brand image and the perceived value?</p><p>• Who has control over the brand, the customer or the company?</p><p>For this study we have used a qualitative approach in which we have conducted eight personal interviews with brand consultants and the editor of the magazine Dagens Media which has given us the foundation for our analysis. We choose this qualitative approach to gain a deeper understanding and a complete picture for the studied topic. In the final chapter we present our conclusions of the study. We have found that consumers can influence and communicate the brand image in five different ways; by using the brand, through word-of-mouth, buzz, engaging in social groups and through Consumer Generated Media (CGM). Another conclusion we have drawn is that the consumer has gained more control over the information flow in the market and thereby their ability to affect the company’s marketing message has increased. The main reason for the consumers improved power is the explosion of media channels that has developed and increased through Internet. Finally we have drawn the conclusion that the brand image can be divided in to two different aspects; the personal and the general image.</p>

Este trabalho de pesquisa é dedicado ao desenvolvimento, análise e implementação de um novo esquema upwind de alta resolução (denominada PFDPUS) para a aproximação de termos convectivos em leis de conservação e problemas relacionados em mecânica dos fluídos. Usando variáveis normalizadas de Leonard, o equema PFDPUS é baseado em uma função polinomial por partes que satisfaz os critérios de estabilidade CBC e TVD. O desempenho do esquema PEDPUS é investigado na solução das equações de advecção de escalares, Burgers, Euler e MHD. O novo esquema é então aplicado para simular escoamentos incompressíveis envolvendo superfícies livres móveis. Para tanto, o esquema PFDPUS é implementado dentro do software CLAWPACK para problemas compressíveis, e no código Freeflow para poblemas incompressíveis. Os resultados numéricos são comparados com dados experimentais, numéricos e analíticos / This work is dedicated to the development, analysis and implementation of a new high-resolution upwind scheme (called PFDPUS) for approximation of convective terms in conservation laws and related fluid mechanics problems. By using the normalized variables of Leonard, the PFDPUS scheme is based on a piecewise polynomical function that satisfies the CBC and TVD stability criteria. The performance of the PFDPUS scheme is assessed by solving advection of scalars, Burgers, Euler and MHD equations. Then the new scheme is applied to simulate incompressible flows involving moving free surfaces. The PFDPUS scheme is implemented into the CLAWPACK software for compressible problems, and in the Freeflow code for incompressible problems. The numerical results are compared with experimental, numerical and analytical data
