ABSTRAKT
Det här är en sammanfattning av den formella delen av vårt projektarbete. Under hösten 2007 och våren 2008 har vi på uppdrag av Egon Nilsson överhalat en hjälpmaskin ombord på Calmare Nyckel. Maskinen var i stort behov av en renovering, det läckte både kylvatten och smörjolja på olika ställen. Det har varit mycket väntetid på reservdelar eftersom maskinen är ovanlig och tillverkas i England. Mot slutet av arbetet råkade vi på bekymmer med vattenläckage i smörjoljan som gjorde att jobbet blev försenat några veckor. Läckaget lagades och maskinen provkördes. Resultatet blev bra, maskinen fungerade och gick som den skulle. Under arbetets gång har vi försökt i möjligaste mån följa de instruktioner som finns i instruktionsboken.
När man genomför ett projektarbete av den här typen, skall all dokumentation rörande projektet redovisas. Materialet som presenteras i den här sammanställningen är upplagt enligt följande. Inledning till ämnet och projektet vilket följs av avsnitten projektprocessen och resultat. Till denna dokumentation har vi bifogat, arbetsdagbok och offert.
ABSTRACT
This is a summary of the formal part of our project. During the autumn of 2007 and spring 2008 we have done an overhaul on one of the auxiliary engines onboard Calmare Nyckel. The assignment was given from Egon Nilson. The engine was in bad shape, lubrication oil and coolingwater was leaking from several cylinders and thereby in big need of a service. There have been some waiting time during the order of new parts because of the rare engine type which are British and therefore all the parts had to be ordered from England. At the end of the project we discovered some difficulties with coolingwater leaking in to the oil sump, this causing further delays finishing the project. The problem were solved and at the test run the engine run satisfactory.
During the project we have as far as possible followed the manual and other instructions available.
During a project like this it is important that all documentation of the project is shown.
The materials that are shown are presented with an introduction followed by the process and the result. To this documentation we have attached a working diary and quotations.

Memory-safe execution of C programs has been well researched but the ability to find memory-safety violations before execution has often been overlooked. One approach for memory-safe C is SoftBoundCETS which infer some memory-accesses as statically safe and others become runtime-checked. One problem with this approach is that it is not obvious to the programmer which checks are runtime-checked and which are inferred as safe. This report analyses the approach taken by SoftBoundCETS by implementing a runtime bounds-checks lister for SoftBoundCETS.The resulting runtime bounds-checks-listing program that can track 99% of the inlined runtime bounds-checks to user program source code lines in programs compiled with -O3 and link-time-optimisation. Analysing SoftBoundCETS with this tool reveals SoftBoundCETS can eliminate about 35% of the memory loads and stores as statically safe in Coreutils 8.27.Mycket forskning har utförts om minnessäker exekvering av C-program men förmågan att hitta minnessäkerhetsöverträdelser har ofta förbisetts. En approach för minnessäker C är Softbound-Cets som härleder vissa minnesaccesser som statiskt säkra och andra blir kontrollerade vid körtid. Ett problem med denna approach är att det inte är uppenbart för programmeraren vilka kontroller som utförs vid körtid och vilka som härleds som säkra. Denna rapport analyserar Softbound-Cets approach genom att implementera ett program som listar fältaccesser för Softbound-Cets. Det färdiga programmet som listar fältaccesser vid körtid kan spåra 99% av inline-expanderade accesskontroller vid körtid till kodrader i användarprogram kompilerade med -O3 och länktidsoptimering. Analysen av Softbound-Cets med detta verktyg avslöjar att Softbound-Cets kan eliminera runt 35% av minnesaccesserna som statiskt säkra bland programmeni Coreutils 8.27.

Full textAbstract:
This thesis examines the day to day practices that constituted Anne Lister's (1791-1840) sexuality and sociability within the range of her writings, as well as her society. Anne's writings were a detailed account, spanning her lifetime, of her own love and relationships with the 'fairer sex' (Whitbread 1988, 145). Anne's sociality, seen in her correspondence and plain handwritten journal entries, has been explored by Muriel Green in Miss Lister of Shibden Hall and Jill Liddington in Female Fortune and Nature's Domain (Green 1992; Liddington 1998; 2003). As a gentlewoman of adequate means, Anne has garnered some attention from women's historians interested in her agency within an early nineteenth century social and historical context. Anne's sexual identity has been extensively analysed over the past nearly twenty years by lesbian feminists, queer theorists, women's historians and historians of sexuality concerned with the history and development of modern Western female homosexuality and gender. The source for theorising Anne's sexuality has been the edited selections of the crypted journal entries, published by Helena Whitbread in I Know My Own Heart and No Priest but Love (Whitbread 1988; 1992). However, many analyses deal either with the theorisation of Anne's sexuality or her sociality; the theoretical difficulty with reconciling these categories has troubled the analysis of her complex subjectivity. Drawing upon the archival materials, I have used an interdisciplinary feminist approach to analyse the sexual and social processes of Anne's everyday interactions in her writings. Taking the seven month period of the sojourn to Paris in 1824-25, I have focused upon Anne's textual practices within her journal volume and letters during her residence in Paris, her social practices with the other guests at the guesthouse 24 Place Vendome and her sexual practices with her lover, the widow Mrs. Maria Barlow. The journal volumes and correspondence are a valuable historical record of one gentlewoman's engagement with early nineteenth century British culture.

Full textAbstract:
Jusqu'en 1980, date à laquelle la variole a été déclarée éradiquée suite à la pratique de la vaccination, elle a constitué un véritable fléau pour l'humanité. Le risque de réémergence du virus de la variole dans un contexte bioterroriste, compte-tenu des conditions de production, de la faible immunité de la population et des complications post-vaccinales liées aux vaccins historiques, rend le développement de nouveaux vaccins antivarioliques nécessaire.L'objectif du travail de thèse présenté dans ce mémoire est l'étude du vaccin antivariolique historique Lister dans un cadre de stratégie d'élaboration d'un nouveau vaccin issu de cette souche.
La séquence génomique de ce vaccin est déterminée et décrite. Sa comparaison avec d'autres souches de virus de la vaccine met en évidence les singularités de la souche Lister.
Par ailleurs, l'étude de la diversité de la population virale et sa caractérisation phénotypique et génétique devraient permettre d'éclairer le choix de la stratégie pour développer un nouveau vaccin dit de deuxième génération issu de cette souche : vaccin constitué d'un seul clone viral ou vaccin polyclonal.
Enfin, l'étude de l'interaction du virus de la vaccine avec la barrière hémato-encéphalique montre une augmentation de sa perméabilité suite à l'infection des cellules endothéliales par le virus de la vaccine. De plus, des études in vivo mettent en évidence l'entrée et la réplication du virus dans le tissu cérébral, entraînant des atteintes cérébrales parfois mortelles. Ces perspectives permettent d'appréhender la neuropathogénicité du vaccin historique reliée aux encéphalites post-vaccinales, complications létales de la vaccination antivariolique.

Rowanchild, Anira. "My mind on paper : Anne Lister and literary self-construction in early nineteenth-century Halifax." Thesis, Open University, 1999. http://oro.open.ac.uk/57998/.
Full textAbstract:
Anne Lister (1791-1840), a provincial gentlewoman of Shibden Hall, near Halifax in the West Riding of Yorkshire, produced between 1806 and her death a four-million-word diary documenting her daily life, intimate thoughts, ambitions, sexual and emotional adventures with women and her musings on the nature of her sexuality. About a sixth is written in cipher. Lister scholarship so far has focused mainly on the social and cultural implications of her writings. This thesis, however, examines the diary as a literary text and considers Lister's deployment of literary forms and structures, strategies and conventions in producing a sense of self. It explores her relationship to contemporary ideas of authorship and to notions of public and private, and investigates the impact of reading in the autobiographical writing of Lister and her circle and the significance of the cipher in her social and sexual self-representation. It asks whether her literary production helped accommodate her self-representation as a traditional country gentlewoman with her unconventional sexuality. The linking theme throughout the thesis, bringing together the many different aspects of Lister's self-fashioning, is the significance of literary considerations in her diary and letters. It begins the work of investigating the literary structures and strategies of her writings, and offers a fresh perspective on this remarkable work of literary self-construction.

Full textAbstract:
The premise of this project was to engineer a novel viral platform with the capacity to enhance antitumour immunity. To this effect, the N1L gene was disrupted in a Lister strain vaccinia viral backbone that had previously been engineered to be tumour selective (VVL15ΔN1L) and armed with transgenes encoding murine and human versions of GMCSF and IL12. In vitro, they retained potency for infecting, replicating in and killing a panel of murine, Syrian hamster and human cancer cells; all viruses were able to express their transgenes to detectable levels upon infection of every tumour cell line. In comparison to the parental virus (VVL15), VVL15ΔN1L administration into immune competent in vivo tumour models (of pancreatic and lung cancer) led to enhanced intratumour (IT) infiltration of neutrophils as well as markedly elevated circulating numbers of natural killer (NK) cells. VVL15ΔN1L also enhanced the tumour infiltration of CD8+ cells. Functional immunoassays and flow cytometric analysis of T cells provided evidence of enhanced tumour specific adaptive immunity. In comparison to VVL15, IT VVL15ΔN1L significantly reduced the growth of subcutaneously implanted syngeneic pancreatic tumours. This effect was predominantly due to cytotoxic lymphocytes, evidenced by the complete abrogation of efficacy upon repeating the experiment in mice that had been depleted of CD8+ cells. A similar treatment schedule reduced the formation of lung metastases from a primary spontaneously metastasising syngeneic lung cancer model; and translated into prolonged short-term post-operative survival when used as neoadjuvant to surgical resection. Efficacy in this context was contrastingly, due to an elevation in systemic NK cells; concurrent depletion of NK cells (but not CD4+ or CD8+ cells) completely abrogated the survival advantage. The IL12 transgene armed recombinant was the most effective antitumour therapeutic. Its IT administration into pancreatic tumours led to complete tumour eradication in over 80% of tumour bearing mice and was effective in slowing the growth of other aggressive flank tumours. Neoadjuvant administration of VVL15ΔN1L-mIL12 into metastatic lung cancers dramatically prolonged long-term post-surgical survival, with apparent cure of 88% of mice.

A resposta inflamatória pode exacerbar o processo lesivo após desordens neurais agudas. O dimorfismo sexual gerado pelas diferentes presenças hormonais existentes entre macho e fêmea têm demonstrado habilidades neuroprotetoras endógenas opostas, apresentando uma melhor preservação da integridade do tecido nervoso na fêmea, putativamente, devido à presença dos hormônios ginógenos. Não existem investigações comparando como essa diferença pode afetar a resposta inflamatória durante o AVE. No presente estudo, investigaram-se as diferenças nos processos inflamatórios agudos do dimorfismo sexual de ratos adultos, de ambos os sexos, submetidos à lesão isquêmica aguda induzida por Endotelina (ET1) no corpo estriado. Seis grupos experimentais foram delineados: Animais machos de 24 horas de sobrevida (n= 8); machos de 72 horas de sobrevida de (n=8); machos de 7 dias de sobrevida (n=8); e fêmeas de 24 horas de sobrevida (n= 8); fêmeas de 72 horas de sobrevida de(n=8); fêmeas de 7 dias de sobrevida. A análise histopatológica geral foi realizada em secções coradas pela violeta de cresila. Macrófagos, astrócitos e neurônios foram identificados por imuno-histoquímica com anticorpos específicos para estas células inflamatórias (ED1, anti-GFAP e Anti-NeuN, respectivamente). Realizou-se contagem de micróglia/macrófagos ativados e corpos neuronais nos grupos experimentais mencionados. Não se notou diferença quantitativa entre os diferentes sexos, contudo houve uma aparente queda na quantidade de macrófagos/micróglia em 3 dias, tanto para os machos quanto para as fêmeas, apresentando alguma diferença na ativação astrocitária mais forte em machos. Os resultados sugerem que as diferenças sexuais na linhagem Lister Hooded, não são suficientes para causar diferenças significativas na preservação do tecido nervoso e em alguns aspectos da resposta inflamatória após a indução de isquemia cerebral por meio de ET1.
The inflammatory response may exacerbate the process harmful after acute neural disorders. Sexual dimorphism generated by different hormonal attendance between male and female have demonstrated neuroprotective abilities endogenous opposite, showing a better preservation of the integrity of the nervous tissue in female, putatively due to the presence of gynoid hormones. However, there is no research work comparing how this difference might affect the inflammatory response during stroke. In the present study, we investigated the differences in acute inflammatory processes of sexual dimorphism in adult rats of both sexes subjected to acute ischemic injury induced by endothelin (ET1) in the striatum. Six experimental groups were designed: male animals survival 24 hours (n = 8); male survival of 72 hours (n = 8); male survival of 7 days (n = 8) and female 24 hours survival (n = 8), females 72 hours of survival (n = 8); female seven days of survival. Histopathologic analysis was performed in the general sections stained with violet cresila. Macrophages, astrocytes, and neurons were identified by immunohistochemistry with antibodies specific for these inflammatory cells (ED1, anti-GFAP and Anti-NeuN, respectively). We conducted counts activated microglia / macrophages and neuron bodies mentioned in the experimental groups. No difference was observed quantitatively between different sexes, but there was an apparent decrease in the amount of macrophages / microglia at 3 days but in males and in females, presenting apparently some difference in the activation of astrocytes was stronger in males. The results suggest that sex differences, at least in lineage Lister hooded is not enough to cause significant differences in the preservation of nerve tissue and in some aspects of the inflammatory response after induction of cerebral ischemia by ET1.

Full textAbstract:
This dissertation comprises an analysis of the interconnections of gender, politics, class, sexuality and female networks as these operated within the recorded life of Anne Lister (1791-1840), a 'masculine' and lesbian member of the minor landed gentry in the West Riding of Yorkshire. A scholar, traveller and businesswoman, Lister left an enormous, approximately four million-word journal, part of which was written in a crypt of her own devising. While other studies have focused on the production of discourses and their effect in creating passively-inscribed identities, this work will focus on Lister's reception of discourses, her active manipulation of these, and her creation of an identity based partly upon class, partly upon gender, and partly upon her sexual practice. Thus, it represents a major revision of at least one of Foucault's basic premises. Few studies have analyzed the role of women in the gentry to this extent. Lister managed a landed estate in an industrializing area. Estate business included coal-mining, quarrying, mill-building, and investments in roads and canals. A staunch Tory Anglican, she felt that her property gave her the right to dictate the votes of her tenants, and this became more possible following the Reform Act of 1832. Over the course of her life Lister had a number of affairs with women in the gentry and aristocracy, but during the period focused upon here, 1830-1840, Lister had settled into a lesbian marriage with another local heiress, Ann Walker. The gendered power dynamics of their relationship are explored, as are the languages Lister uses to record sexual practice. Lister maintained an extensive correspondence with women in the gentry and aristocracy up to the time of her death. These networks operated both as systems of support and systems of constraint. After her death, the property arrangements she had made with her partner caused difficulties for both families. Property laws recognized only heterosexual transmission, upon which the landed gentry depended for its survival. The Lister journals represent the earliest and most detailed personal evidence of upper-class lesbian lives known to Western historians. The wealth of detail available in matters of gender, class, politics and women's networks is also unprecedented. The journals are thus a vital source in women's history. They simultaneously show how Lister and the women in her world were fundamentally shaped by the dominant discourses of their time while also demonstrating the power of women's agency to resist and shape those discourses for their own benefit.

Full textAbstract:
INTRODUÇÃO: As doenças retinianas associadas à neovascularização, tais como a degeneração macular relacionada à idade e as retinopatias diabética e da prematuridade são as principais e mais importantes causas da cegueira em todo o mundo. Nos últimos anos, injeções intravítreas de fármacos com ação antiangiogênica, como o bevacizumabe (BVZ), têm sido de grande valia tanto em pacientes na fase adulta quanto nos recém-natos. Todavia, estudos experimentais in vitro e in vivo sugerem que essas drogas promovam efeitos adversos sobre alguns processos celulares, interferindo diretamente em mecanismos fisiológicos que mantém a homeostase do tecido retiniano, incluindo os mecanismos de proliferação, diferenciação e morte celular. OBJETIVO: investigar o efeito do BVZ nos processos de transcrição e tradução de marcadores da gliose: GFAP e vimentina, de morte celular, caspase-3 e beclina-1, e dos proteoglicanos relacionados à manutenção e desenvolvimento de tecido retiniano: neurocam, fosfacam e sindecam-3. MÉTODOS: Dois modelos experimentais foram usados nesse estudo: 1) linhagem celular de Müller de Glia humana adulta (MIO-M1), cultivada em meio de cultura D-MEM na presença e ausência de BVZ por 12 e 24 horas nas concentrações de 0,25 mg/mL e 0,50 mg/mL e 2) explantes de retinas de ratos 2 dias pós-nascidos submetidos à 0,50 mg/mL da droga por 48 horas. Durante este período foram mantidos a 5% de dióxido de carbono à temperatura de 37°C. A análise de proteínas foi realizada por imunocitohistoquímica e Western Blotting e a expressão de RNAm, pela reação em cadeia da polimerase em tempo real (PCR Real Time). Foi utilizado o Teste de ANOVA - fator único para a comparação entre os grupos controle e tratados com BVZ de um mesmo período (12h ou 24h) e o teste t de Student para a comparação entre as mesmas concentrações de 12h e 24h, e para a comparação entre os grupos controle e tratado com BVZ dos explantes (p < 0,05). RESULTADOS: Nas células MIO-M1, o BVZ, aumentou a expressão gênica e diminui a tradução de VEGF na concentração de 0,50 mg/mL em 24h comparado a 12h. Para o GFAP, houve um aumento da transcrição em 0,50 mg/mL em 24h comparado a 12h e aos outros grupos em 24h. Entretanto, houve diminuição da tradução para estes mesmos períodos e condições. Para a vimentina, houve aumento na transcrição em 0,50 mg/mL após 24h. Os achados de beclina-1 revelaram uma diminuição da transcrição e tradução em 0,25 mg/mL em 24h comparado a 12h. A transcrição entre os grupos do mesmo período aumentou nos grupos tratados com BVZ tanto em 12h quanto em 24h. A tradução da beclina-1 diminuiu em 0,25 mg/mL, mas aumentou em 0,50 mg/mL em 24h em relação à 12h. A comparação entre os grupos de 24h revelou aumento da tradução em 0,50 mg/mL. Para a caspase-3, houve diminuição da transcrição em 0,25 mg/mL e 0,50 mg/mL em 24h em relação a 12h e entre nos grupos tratados com BVZ em 24h. A tradução revelou um aumento em 0,50 mg/mL em 24h em relação a 12h. No fosfacam, houve diminuição da transcrição em 0,50 mg/mL em 24h comparado a 12h e entre os grupos tratados com BVZ e controles para 12h e 24h. A transcrição de neurocam diminuiu em 0,25 mg/mL e 0,50 mg/mL em 24h comparado a 12h e entre os grupos tratados com BVZ e controles em 12h e 24h. A tradução aumentou em 0,50 mg/mL em 24h em relação a 12h, mas diminuiu entre os grupos em 24h. Nos explantes, a transcrição e tradução de VEGF diminuiram no grupo tratado com BVZ após 48h. CONCLUSÃO: Nossos resultados relacionados às células MIO-M1 e ao explante de ratos, in vitro, nos permitem aventar o possível comprometimento ocasionado pela depleção do VEGF pelo BVZ na homeostase do tecido retiniano, in vivo, interferindo nas moléculas envolvidas na morte e diferenciação celular e na neuroproteção em indivíduos em fase adulta e recém-natoBackgraound: Vasoproliferative retinal disorders such as age-related macular, degeneration, diabetic retinopathy and retinopathy of prematurity are major causes of blindness in the world. In recent years, intravitreal injections of drugs with antiangiogenic action, as bevacizumab, have been very useful for both patients in adulthood and in newborns. However, experimental studies, in vivo and in vitro, suggest that antiangiogenic drugs may promote side effects in cellular proceedings, interfering directly in physiological mechanisms of cellular proliferation, differentiation and death. POURPOSE: Investigate the bevacizumab effects in transcription and translation processes of gliosis, GFAP and vimentin, cellular death markers, caspase-3 and beclin-1, and proteoglycans involved in retinal tissue maintenance and development, neurocan, phosphacan and syndecan-3. METHODS: Two experimental models were used on this research: cellular lineage of adult and human Müller glial cell(MIO-M1) were cultivated on D-MEM medium with 0,25 and 0,50 mg/mL bevacizumab for 12 and 24 hours, and two days old rat retinal explants submitted to 0,50 mg/mL for 48 hours. During this period were stored in laboratory ovens at 5% carbon dioxide pressure and 37 °C average temperature. Molecular techniques were used to evaluate gene expression and protein content. Protein assessments were performed by immunocytochemistry and western blotting analysis, while Real Time PCR was used to measure mRNA content. ANOVA tests one factor were applied to compare the control and BVZ groups of the same period (12h or 24h) and t test from Student to compare the same conditions of 12h and 24h, and to compare the control and BVZ retinal explants groups (p<0.05). RESULTS: At MIO-M1 cells, BVZ increased the gene expression and reduced the translation of VEGF at concentration of 0.50 mg / mL in 24 hours compared to 12 hours. For GFAP, there was an increase of transcription at 0.50 mg / mL in 24 hours compared to 12 hours and to the other groups at 24 hours. However, there was a decrease in translation for these same periods and conditions. For vimentin, there was an increase in transcription at 0.50 mg / mL after 24 hours. The beclin-1 findings revealed a decrease of transcription and translation at 0.25 mg / ml compared at 24 h compared to 12h. Transcription among groups increased in BVZ treated groups at 12h and 24h. The translation of beclin-1 decreased at 0.25 mg / ml, but increased at 0.50 mg / mL at 24 hours compared to 12 hours. The comparison between the groups at 24h revealed an increased in translation at 0.50 mg / mL. For caspase-3, there was a decrease in transcription at 0.25 mg / ml and 0.50 mg / ml at 24 compared to 12 hours and among BVZ treated groups at 24h. Translation revealed an increase at 0.50 mg / mL at 24 hours compared to 12 hours. For fosfacam, there was a decreased in transcription at 0.50 mg / mL in 24 hours compared to 12 hours and among BVZ treated groups and controls at 12h and 24h. The transcription of neurocam decreased at 0.25 mg / ml and 0.50 mg / ml at 24 hours compared to 12 hours and among BVZ treated groups and controls at 12h and 24h. Translation increased at 0.50 mg / mL at 24 compared to 12 hours, but decreased among the groups at 24 hours. For explants, transcription and translation of VEGF decreased in the BVZ group treated after 48h. CONCLUSION: Our results related to the MIO-M1 cells and explants of rats,in vitro, allow us to suggest the possible impairment caused by depletion of VEGF by BVZ in the homeostasis of retinal tissue, in vivo, interfering in the molecules involved in cell death and cell differentiation and neuroprotection in individuals in adulthood and newborns

Full textAbstract:
The genotoxicological effects of five intra-peritoneal administered oestrogens (17β- oestradiol, daidzein, diethylstilboestrol, genistein, and equol), were examined. Male hooded- Lister rats were used to examine to what extent DNA damage occurred. The alkaline Comet assay was the chosen method used to assess double-strand DNA breakage by examining the Olive tail moment and %age tail DNA. Tissues from the testis, bone marrow, liver and blood were analysed after an 8-day duration of exposure. Statistically significant increases in DNA damage were observed in the testis with daidzein and in the blood with diethylstilboestrol.
In addition, a further study was carried out to examine the effects of bulk and nanotised forms of non-steroidal anti-inflammatory drugs (NSAIDs), aspirin and ibuprofen, in the Comet and micronucleus assays, on whole blood taken from prostate cancer patients or volunteers. These were used because it is known that the sensitivity of DNA to genotoxins can be heightened in patients with cancer. Patients’ and volunteers’ blood was cultured with either the bulk or nano-forms for 44 hours at 37°C, 5% CO2. Data were obtained for the Comet assay as above and the number of binucleated cells scored for the micronucelus assay. The results show the nanotised forms of the NSAIDs decreased the levels of strand breakage and lowered the numbers of micronuclei generated compared with their bulk forms. There was no clear difference between the sensitivity of the healthy controls and the prostate cancer patients, with only one individual showing evidence of heightened sensitivity.

Full textAbstract:
This thesis examines domestic service practises among some members of the Yorkshire gentry during the nineteenth century. Historians usually consider the gentry to have shared the same social outlooks and practises as other members of the upper class in spite of significant differences in income and political power. However, as they were less well-to-do, they could not afford to maintain the variety of servants a wealthy aristocrat could. Three main families were selected to reflect the range of incomes and possession or lack thereof of a hereditary title: the Listers of Shibden Hall, the Sykes of Sledmere House and the Pennymans of Ormesby Hall. The Yorkshire gentry organised country houses servants along the same hierarchical lines as prescriptive authors suggested because this gave servants clear paths for promotion which reduced the frequency of staff turnover; furthermore the architecture of their country houses promoted such organization. Secondly, this architecture reinforced the domestic social positions of every rung of the domestic hierarchy. As part of a unique subgroup of the upper class, gentry ladies were less likely to experience class conflict with servants clearly placed within the domestic service hierarchy. The conclusion is that through selective recruitment processes, the distinctive work environment and a particular labour pool, this group created a unique labour market tailored to their social and economic standing.

Weiterführende Untersuchungen zeigten, dass SO 94- und SO 19-VVOV in zwei weiteren Modellsystemen immunstimulatorisch aktiv sind. Im Baculo-Virussystem exprimierte Proteine waren nur in Kombination mit Vaccinia Lister-Virus (VV) wirksam. Dabei zeigten jeweils Virus-Protein-Gemische mit dem geringsten Proteinanteil den stärksten immunstimulatorischen Effekt. Proben in denen VV durch bovines Herpes-Virus-1 ersetzt wurde, sind dagegen nicht wirksam. Dies lässt auf eine Beteiligung VV-spezifischer Faktoren schließen. Übereinstimmend mit diesen Ergebnissen führte eine Frameshift-Mutation in ORF 94r von SO 94mut-VVOV nur zur Abschwächung und nicht zum vollständigen Verlust der immunstimulatorischen Wirkung. Beide in Schizosaccharomyces pombe exprimierten Proteine, sp-ORF19 und sp-ORF94r, induzierten keinen signifikanten Schutz im Aujeszky Maus Modell. Mit der Identifikation einzelner immunstimulatorisch aktiver PPVO-Komponenten ist es erstmals gelungen, den paramunisierenden Effekt von Parapox-Viren einzelnen viralen Genen zu zuordnen. Insbesondere stellen SO 94- und SO 19-VVOV viel versprechende Kandidaten für die prophylaktische bzw. therapeutische Anwendung in verschiedenen Indikationen als auch für weitere Untersuchungen des Wirkmechanismus dar.

Tidigare tester framhåller förhållandet 1:8 när det är till för konstruktionsändamål, denna studie hävdar att 1:3 är tillräckligt för lister.Could scarf jointing be an economical suitable complement to finger jointing? Knot-free lath material of pine wood is highly requested in the timber industry where finger jointing nowadays is a commonly used method. It is important that the lath material has a handling strength good enough to hold the assembly since structural strength is not the limited factor. This study contains a comparison of tensile strength in laths made of finger joints, MDF (Medium Density Fibreboard) and scarf joints where the lowest ratio of angular relationship that meets the demands of the scarf is searched from 1:1 to 1:5. Previous testing only holds a ratio of 1:8 for construction purposes whereas this study claims a result of 1:3 for laths.

Thesis, University of Bradford, 2012. http://hdl.handle.net/10454/5481.
Full textAbstract:
Phencyclidine (PCP) is a non-competitive NMDA receptor antagonist that has been shown to induce schizophrenia-like psychotic symptoms that are clinically indistinguishable from schizophrenia in patients. When administered to rodents, PCP produces an array of behaviours that are characteristic of schizophrenia. Schizophrenia is associated with continual and treatment resistant cognitive deficits which are now recognised as a core feature of the disease. The aim of the studies reported in chapter 3 were to establish a set of objects with equal preference in the NOR (novel object recognition) test. Furthermore, the inter-trial-interval (ITI) of the NOR test was investigated in an attempt to elucidate the effects of time and location of the rats during the ITI on the cognitive impairments following sub-chronic PCP treatment. The experiments in chapter 4 were designed to compare the performance of male and female rats in the NOR test following treatment with acute d-amphetamine (d-amph), PCP and sub-chronic PCP treatment. In chapter 5, validation of the cognitive deficits induced by sub-chronic PCP treatment was assessed using carefully selected pharmacological agents. The aim of the studies in chapter 6 was to determine the effects of isolation rearing on cognitive performance in the NOR test following increasing ITIs. Additionally, the sensitivity of isolation reared rats compared to social controls following acute administration of PCP and d-amph was assessed using the NOR test. Studies in chapter 8 utilised the 16-holeboard maze to determine the effects of acute treatment with d-amphetamine, PCP and scopolamine on working memory in the rat. NOR is a visual learning and memory test that measures recognition memory which is impaired in patients with schizophrenia. Studies presented in this thesis demonstrate the importance of careful pilot studies when selecting objects for use in the NOR test. Initial studies in sub-chronic PCP (2 mg/kg for 7 days followed by 7 days drug free) treated female hooded-Lister rats revealed a preference of the rats for the wooden cone object; subsequently this object was eliminated from further NOR experiments. Sub-chronic PCP treated rats were found to be highly susceptible to the disruptive influence of distraction during the short 1 min inter-trial-interval (ITI) in the NOR test. These results are consistent with clinical findings of the effects of distraction on cognition in schizophrenia patients. Following the initial validation experiments, a 1 min ITI in the home cage was selected for all subsequent NOR studies. Further experiments provided evidence to confirm that information presented in the acquisition trial is encoded but not retained in the retention trial of the NOR test by IV PCP-treated rats. Male rats were less sensitive to the recognition memory deficits induced by acute treatment with PCP and d-amphetamine compared with females. Following sub-chronic PCP treatment, both males and females showed object recognition deficits, however, the impairments were more robust in female rats. Female rats were therefore selected for all subsequent experiments. Pharmacological validation was carried out using carefully selected agents which were assessed for their ability to restore the sub-chronic PCP induced cognitive deficit in the object recognition test. It was found that the classical antipsychotic agents haloperidol and fluphenazine, the benzodiazepine anxiolytic chlordiazepoxide and the SSRI antidepressant fluoxetine were ineffective. Further studies showed that the atypical antipsychotic agents, clozapine and risperidone, the analeptic agent modafinil, the nAChR full agonist nicotine, and full agonist and positive allosteric modulator of the α7 nAChR (PNU-282987 and PNU120596 respectively) reversed the recognition memory deficit induced by sub-chronic PCP treatment in the NOR test. Isolation rearing of rats at weaning is an environmental stressor that has relevance for modelling the symptomatology and pathology of schizophrenia. Isolates had a significantly increased locomotor activity (LMA) response to a novel environment and enhanced sensitivity to time delay-induced recognition memory deficits, compared with their socially reared counterparts. Isolates were less sensitive to an acute PCP-induced recognition memory deficit but more sensitive to an acute d-amphetamine induced recognition memory deficit in the NOR test compared to social controls. Preliminary results from the 16-holeboard maze experiments reveal that acute administration of the mAChR antagonist scopolamine, d-amphetamine, PCP and sub-chronic PCP treatment reduced working memory scores compared to vehicle treated controls. Taken together, these findings suggest that sub-chronic treatment with PCP induces cognitive deficits in behavioural tests of relevance to cognition associated with schizophrenia. This may allow the detection of novel pharmacotherapies to alleviate these cognitive deficits and exploration of the nature of cognitive disturbances in these patients.

Full textAbstract:
Mastering the physical aspect of piano technique has long been a topic of great interest and importance to pianists. This is borne out in the numerous pedagogical approaches on the topic of piano technique. Despite the many contributions from pedagogues and scholars in developing an understanding of piano technique, many conflicting approaches often cause more confusion than clarity. After reviewing the literature on pedagogical approaches to piano technique, this study determined that problematic language might lie at the root of the confusion. Core concepts identified in the review of literature as recurring areas of misunderstanding were tension, relaxation, co-contraction, arm weight, and hand and finger shape.
The purpose of this study is to seek where issues of language exist in contemporary piano pedagogical approaches and to show how these problems may contribute to the systemic confusion in piano technique. To do this, the language that is used to describe and define the core concepts identified in the review of literature is analyzed in five modern pedagogical approaches. Five authors who have developed approaches that reflect current trends in piano technique have been selected for this study: Barbara Lister-Sink; Dorothy Taubman; Thomas Mark; Fred Karpoff; and Alan Fraser. The first step of this study entails collecting data from each of the five pedagogical approaches. The data is then analyzed for consistency and accuracy. Problems in language that contribute to the inconsistencies and inaccuracies are examined and illustrated with material from the data collection.
This study concludes by identifying the main sources of confusion in the use of language: inconsistent and inaccurate use of terms; wavering between scientific, common, and invented language; challenges in describing opposing qualities that come from tension and relaxation; and failing to discern between the individual subjective experience and the mechanics of movement. By recognizing where the problems in language exist, this study represents an important first step for the pedagogical community to reach a common understanding of the language used to describe the physical aspect of piano technique.

Full textAbstract:
The seed germination process during sprout production provides suitable environmental conditions for the growth of pathogenic bacteria, such as Listeria monocytogenes. A potential way to control this bacterial growth is through the use of bacteriophages, which are naturally occurring viruses that specifically attack bacterial targets and have been shown to be effective antimicrobials in some foods. Therefore, the objective of this study was to evaluate the antimicrobial susceptibility of L. monocytogenes to bacteriophage on alfalfa sprouts during seed germination and subsequent refrigerated storage at 4 °C. Alfalfa sprout seeds were dip-inoculated with 5.5 x 105 CFU/ml L. monocytogenes serogroups 1 and 4. This was followed by treatment with the commercial bacteriophage LISTEX™ P100 at a concentration of 5.3 x 107 PFU/ml. The seeds were then soaked and germinated for 80 h using the glass jar method. The concentration of L. monocytogenes was determined every 24 h using PALCAM agar plated in triplicate. When compared to the spiked, untreated control, treatment of sprout seeds with LISTEX™ P100 resulted in a statistically significant (p < 0.05) reduction of 1.6 log10 CFU/g L. monocytogenes after the initial 24 h of germination. However, the bacteriophage did not show a lasting inhibitory effect, with no statistically significant reductions in L. monocytogenes growth as compared to the control at subsequent time points. The bacteriophage remained stable over the entire germination and storage period. Although biocontrol of Listeria with bacteriophages has high potential to serve as an alternative strategy to control foodborne illnesses, factors such as phage delivery and dose optimization in sprouts need to be further investigated.

Full textAbstract:
Adaptation of personal experiences to a screen is no new concept, in fact it is the driving force to media content creation. All storylines and narratives are related to personal experience whether literally or metaphorically. These experiences are externalized in media by many forms, ranging from the visible and audible. Mainstream media is tied to an entertainment purpose, regardless of themes and topics presented. Therefore, it is important to understand that some of the depictions presented in media are linked to stigma or misrepresentation. This is particularly true for portrayals of mental illness and experiences of trauma. I plan on exploring how media, specifically animation, can communicate subjective experiences of mental illness and trauma. In my exploration I will also speak about the role of abstract and experimental animation in this endeavor. While live action contains an element of reality in contextualizing events or experiences, animation allows one to take full control of the visual representation of a subject and agency over constructing a narrative. Animation is a means of inquiry that exemplifies an art form and a journey of self-discovery. I created a short experimental film reconstructing my subjective experience with childhood sexual trauma. I will embrace visually stimulating abstract animation and stop motion to create an evocative visualization of my personal experience. This means of visual production takes the process of subjective experience a step further and literally becomes a process of laborious and tedious composition, culminating with a personal narrative piece.

Full textAbstract:
In this thesis it is recognised that marketing has a dual role to satisfy both customer and shareholder objectives. The issue of shareholder value creation of marketing is an important and immediate agenda for marketing executives, management and academics. To date, marketers have not been able to adequately quantify and measure shareholder value creation through marketing assets and marketing expenditure. This has led to a dilution of marketing power and influence in the boardroom with management tending to treat marketing as discretionary expenditure and not as an asset. Academics have responded with conceptual models that relate marketing assets back to shareholder value, generally through cash flow or sales models. The creation of shareholder value through marketing assets and expenditure is then conceptualised and tested empirically. The conceptual model builds on the theory of agency and incomplete markets setting to illustrate the flow effects through marketing assets to shareholder value. The conceptual model also demonstrates that marketing expenditure can have stock and/or flow impacts on shareholder value. Flow effects are indirect effects that are mediated through sales, cash flows, and earnings and can be either temporary or longer term. It is concluded that in listed markets stock prices are the general surrogate for shareholder value, and risk adjusted earnings are the appropriate surrogate in non-listed markets. The thesis then empirically illustrates and tests the relationships between marketing communications expenditure on two data sets representing firms in listed and non-listed settings. The empirical results reveal that marketing expenditure does play an important role in the creation of shareholder value and that stock and flow effects are both present. Knowledge of the various empirical impacts from marketing across firm size, industry and listed and non-listed market settings observed in this thesis should prove highly valuable for marketers and managers. Finally, a conceptual understanding by marketers of the financial metrics that are required to be influenced in order to increase shareholder equity will provide greater clout in negotiations with management and boards of directors.

Full textAbstract:
In this study, two different system were studied to investigate the forces interacting in thin liquid films. In the former, direct force measurements were conducted with bitumen-coated mica surfaces using a Mark IV surface force analyzer. Besides long-range electrostatic repulsive forces at separation distances above approximately 70 nm, unexpectedly strong repulsive forces were measured at shorter separation distances. These non-DLVO forces may be attributed to the steric repulsion between asphaltenes extracted on the bitumen surface. The steric forces increased with pH and temperature, which may be explained by the increased solubilization of asphaltenes in water. The steric force also increased with electrolyte concentration, possibly due to a decrease in the mobility of the tails of the asphaltenes on the surface.
The kinetics of coalescence of bitumen droplets was studied by measuring the induction time. There was a general agreement between the force data and the kinetic information, suggesting that bitumen suspensions are stabilized by asphaltene. The steric forces identified by the direct force measurements may have profound implications on the hot water processing of Alberta Tar Sands.
In the later, a thin film balance (TFB) of Scheludko and Exerowa-type was used to determine equilibrium film thicknesses of dodecylammonium chloride and sodium dodecyl sulfate solutions. The hydrophobic force as a third component of the extended DLVO theory was represented as a power law. The results showed that at low surfactant concentrations, the hydrophobicity parameter, K232 is positive and decreases with increasing surfactant concentration. By extrapolating this data for the zero surfactant concentration, K232 was found about 10-17 J, which is approximately 270 times larger than the Hamaker constant, A232. These results suggest that air bubbles are hydrophobic and the hydrophobicity decreases with increasing surfactant concentration..
The disjoining pressure isotherm for both surfactant systems in the presence of inorganic electrolyte (NaCl) were also obtained. The results indicated that the K232 values estimated from the equilibrium film thickness measurements can be used to fit the experimentally obtained disjoining pressure isotherm. Consideration of hydrophobic force predicted a rupture thickness larger than predicted using the DLVO theory, but is substantially smaller than the experimental result. This discrepancy may be ascribed to the hydrodynamic force operating in the film thinning process.
To compare the hydrophobicity of air bubbles and solid surfaces, an air bubble was simulated by using a hydrophobic solid surfaces. The equilibrium contact angle of aqueous surfactant solutions on hydrophobic surfaces was measured using a contact angle goniometer. The results indicated that the nature of both the air-water interface and the solid-water interface is altered gradually from hydrophobic to hydrophilic with increasing surfactant concentration. The results also suggested that the hydrophobicity of both systems are comparable, i.e., K232 is about 10-17 J, which is estimated using the extended DLVO theory, and K131 is in the order of 10-16 J, which is obtained by direct force measurements between the hydrophobic surfaces. It was showed that hydrophobic forces much higher than the London-van der Waals forces for both systems need to be included when the stability of foams and colloids is considered.Ph. D.

Full textAbstract:
This study explores the relationships between listed companies and their shareholders
by investigating the shareholder communication practices of seven listed companies
in Australia. Interviews and document analysis techniques were used to explore how
a listed company's understanding of its relationships with its shareholders shapes its
communication practice. Recognising the strong focus, within the field of public
relations practice, on relationship management, this study explores the assumptions
underpinning the listed company-shareholder relationship from the company
communicator's perspective, and how such assumptions guide and shape changes in
the relationship.
This study draws from the work of Grunig (1989) on the role of worldview in public
relations practice, and the assumptions that drive practice under different worldviews.
The traditional worldview of asymmetrical practice is examined and its relevance in
contemporary financial public relations practice established. The assumptions
governing the idealised worldview of symmetrical practice are also examined and the
constraints on implementing such an approach within the listed company-shareholder
relationship are identified.
The understanding of the listed company-shareholder relationship posited by the
informants to the study is explored through a conceptualisation of company and
shareholder roles. Four major roles played by the company in enacting shareholder
communication are identified, as are two roles created by the company for
shareholders to play. These roles highlight the importance of communication in
establishing and nurturing the listed company-shareholder relationship. The roles also
indicate the tensions that arise when implementing a communication program to meet
the diverse needs of shareholder publics within a regulated environment.
The increasingly competitive nature of the world's financial markets and the global
trend towards greater share ownership are driving a search for improved means of
managing shareholder relationships. This study highlights the importance of the
assumptions guiding the relationship development process when considering change. Such assumptions include the participation of parties in the relationships, the position
and enactment of power in the relationships, and the influencing nature of regulated
communication practices. While recognising that shareholder activism is challenging
the existing system and that new technology has been identified as the key to
empowering shareholders, this study argues that significant change will not be
achieved without fundamental change in the assumptions that guide shareholder
participation in listed companies

¿Cómo preparamos a los niños al mundo competitivo del siglo XXI?1 En el mundo continúa la tendencia creciente por el uso de la tecnología para actividades cotidianas y profesionales, y parte de esta digitalización se da en la lectura y la educación. Los niños y jóvenes de esta época son intensamente estimulados con información, el acceso a Internet y gran variedad de herramientas como ordenadores, softwares disponibles, smartphones, tablets, reproductores etc.2 Por otro lado, en la actualidad, sobre todo en países sub-desarrollados o en vías de desarrollo, existe una brecha preocupante acerca de la comprensión lectora y auditiva; no es que los niños y jóvenes no sepan leer3, sino que no comprenden lo que leen. ¿Cómo pueden saber leer y no entender? puntos clave como La Entonación4, la capacidad de aprender a escuchar y a escucharse, son determinantes. La educación a todo nivel se basa en la lectura, y una persona que no entiende lo que lee, tendrá dificultades extras el resto de su vida profesional y actuará perjudicando también en la capacidad de escuchar y la expresión oral. El presente Plan de marketing consiste en plantear la estrategia comunicacional óptima para el primer año de operación de lili.cl, un sitio web que cubre las necesidades de lectura de los estudiantes escolares de Media de los GSE ABC 1, C2 y C3 de chile. La librería virtual usa el formato de audiolibros debido a su amplia lista de beneficios, sobre todo para personas que como los estudiantes escolares, están desarrollando sus capacidades de comprensión lectora y expresión oral, además de ser virtual, medio con el cual ellos están muy familiarizados y se sienten más cómodos. La proyección de ventas del primer año asciende a CLP$ 1,188,000,000. Para esto se invertirá en el plan de marketing un presupuesto total de CLP$ 174,262,595.

Les sujets âgés sont souvent atteints de nombreuses comorbidités. Leur prise en charge thérapeutique selon les recommandations en vigueur peut être à l’origine d’une polymédication. La prescription de psychotropes est fréquemment retrouvée dans les traitements des sujets âgés. Cette classe thérapeutique est à haut risque iatrogène potentiel dans cette population vulnérable. Les effets indésirables médicamenteux les plus notables sont les chutes, les fractures et les troubles confusionnels. L’identification des psychotropes potentiellement inappropriés (PPI) chez les sujets âgés à l’aide de la liste de Beers a fait l’objet de peu de travaux.Les objectifs de cette thèse étaient d’identifier les prescriptions de psychotropes potentiellement inappropriés (PPI) à l’aide des listes de Beers actualisées dans les traitements de sujets hospitalisés ou vivant en Etablissement d’hébergement pour personnes âgées dépendantes (EHPAD). Les facteurs liés à ces prescriptions ont aussi été recherchés.La polymédication, ainsi que les troubles neuropsychiatriques du sujet âgé doivent rendre le prescripteur de psychotropes particulièrement vigilant dans cette population particulièrement vulnérable.L’usage des listes de médicaments potentiellement inappropriés (MPI) pourrait permettre d’identifier les psychotropes au rapport bénéfice risque défavorable chez les sujets âgés. Et orienter le choix du prescripteur vers des traitements plus favorables au patientElderly people often have many comorbidities. Therapeutic management according to the recommendations in force may be at the origin of a polymedication. The prescription of psychotropic drugs is frequently found in the treatment of elderly patients. This therapeutic class is at high potential iatrogenic risk in this vulnerable population. The most notable adverse drug reactions are falls, fractures and confusion. The identification of potentially inappropriate psychotropic medications (PIP) in elderly subjects using the Beers list has received little attention.The objective of this thesis was to identify the prescriptions of potentially inappropriate psychotropic drugs (PIP) using the updated Beers lists in the treatment of subjects hospitalized or living in the nursing home. Factors related to these treatment s were also investigated.Polymedication, as well as neuropsychiatric disorders in the elderly, should make the prescriber of psychotropic drugs particularly vigilant in this particularly vulnerable population.The use of lists of potentially inappropriate medications (PIM) could identify psychotropic drugs with an unfavorable risk-benefit ratio in elderly subjects. And direct the choice of the prescriber towards treatments more favorable to the patient

ABSTRACT This thesis investigates the legal and theoretical basis of continuous disclosure regulation in Australia as it applies to listed companies. An empirical study is undertaken to further investigate the operation of the legislation. As part of the Enhanced Disclosure regime, the continuous disclosure provision was effective from 5 September 1994 as s1001A of the Corporations Law, now the Corporations Act 2001 (Cth). This statutory provision is replaced by s674, inserted by Schedule 2 to the Financial Services Reform Act 2001 (Cth), and effective from 11 March 2002. The provision reinforces Australian Stock Exchange (ASX) listing rule 3.1. The rule requires a listed disclosing entity to notify ASX immediately of information that would be expected to have a �material effect� on the share price of the company. However, the disclosure requirement is weakened by a number of specific exemptions or �carve-outs� to listing rule 3.1. If a reasonable person would not expect the information to be disclosed, and if the confidentiality of the information is maintained, then disclosure is not mandatory in special circumstances. This study analyses 427 query notices, issued by ASX to listed companies from July 1995 to April 1996. The queries request information concerning unexplained movements in a company�s share price or a failure to comply with the listing rules. An analysis of the companies� replies to these notices provides a profile of the type of company that is likely to be queried. The study also attempts to evaluate the extent to which these companies have relied on the �carve-outs� as an exemption to the regulation.

Il arrive parfois lors de l'utilisation de la méthode multi-liste que les listes administratives ne couvrent pas exactement la même période. On appelle ce problème un problème de listes incomplètes. La façon la plus courante pour résoudre ce problème est de se servir exclusivement des parties des listes où il y a un chevauchement complet. Cette méthode entraîne beaucoup d'imprécision.
Afin de tenir compte de toute l'information disponible, il est possible de modéliser conjointement les strates. Deux méthode de modélisation conjointe sont présentées. Premièrement, il est possible d'estimer les valeurs manquantes à l'aide le l'algorithme EM et ainsi travailler avec des listes complètes. Deuxièmement, un modèle log-linéaire avec effet de strate qui permet de tenir compte de toute l'information tout en demeurant beaucoup plus simple à utiliser. En mesurant l'efficacité de façon explicite, on voit que la modélisation conjointe est plus avantageuse que la modélisation strate par strate.

German listed firms have been allowed by law some choice of a set of Generally Accepted Accounting Standards (GAAP) in the preparation of their consolidated accounts since 1998. This thesis examines the relationship between non-financial German firms' specific characteristics and their choice of GAAP in the financial year ending 2001 using data obtained from Hoppenstedt's Aktienführer. The study is conducted on firms from two divisions of the Frankfurt Stock Market. The section on the Main Market analyses the GAAP choice of 295 firms between internationally recognized accounting standards (IRAS, which includes International Accounting Standards (IAS or IFRS) and U. S. GAAP) and German GAAP (GGAAP). The analysis of 244 Neuer Markt firms reviews the choice between IAS and U. S. GAAP, as such firms must choose one of the two internationally recognised approaches. Statistical analysis was undertaken at three different levels: univariable, bivariable and multivariable analysis. However, conclusions are based on the results of the multivariable analysis, namely multivariable logistic regression models. Results show that the choice of IRAS by Main Market companies is statistically positively associated with their size, being in a quality segment, having a Big-5 auditor and having foreign managers, but is statistically negatively associated with managers' holding equity. In the Neuer Markt, on the other hand, the choice of U. S. GAAP rather than JAS is statistically positively associated with having a subsidiary in the USA, having a Big-5 auditor, and the presence of U. S. investors, but is significantly negatively associated with leverage and profitability. Furthermore, the choice of U. S. GAAP in the Neuer Markt is also a function of being in specific industry sectors. The choice of U. S. GAAP in the Main Market, on the other hand, is significantly positively associated with having a U. S. listing and marginally positively associated with free float.

Thesis (MBA (Business Management))--University of Stellenbosch, 2007.ENGLISH ABSTRACT: Private equity has been dominating the news recently both as an asset class and a tool to facilitate market efficiency in South Africa. Many private equity funds have had good returns in recent times. However, many pension funds still shun away from this asset class, mainly due to lack of understanding of the risk inherent in this asset class, and in its potential overall risk diversifying characteristics. Regulation 28 of the Pension Fund Act, prescribes maximum allocation of five percent to unlisted assets and that includes private equity as an asset class. One of the reasons why investors don't understand this asset class is the lack of comparable data relative to the listed asset classes such as listed equities and listed bonds. From these asset classes, people get data on a daily basis and they are able to understand the daily prices and values of their portfolio. They can also try to value the individual stocks within their portfolio by using variables such as price earnings ratio and dividend yields, as that information is freely available. This research tries to use the listed private equity companies to establish a Private Equity Index. The criteria used are the same as the ones used by Bilo, Christophers, Degosciu and Zimmennann (2004) when they created a Listed Private Equity Index (LPE), which is made up of 114 global listed private equity companies mainly from Europe and North America. The South African Index was created from six companies, and even though the sample looks small, the results were good enough to justify further studies on the same line and to encourage more listings of these types of companies. The Index was then analysed using modem portfolio analysis and optimisation tools to understand the risk and return characteristics of this asset class and how it behaves when blended with other asset classes. The results suggest that this asset class is under allocated and there is a need to create a more representable index even on an IRR basis.
AFRIKAANSE OPSOMMING: Privaataandele het onlangs die nuus oorheers, beide as 'n bateklas sowel as 'n instrument om die markdoeltreffendheid in Suid-Afrika te fasiliteer. Talle privaataandeelfondse het onlangs goeie opbrengste opgelewer. Baie pensioenfondse skram egter steeds weg van hierdie bateklas, hoofsaaklik weens 'n kennisgebrek van die risiko wat inherent is aan die bateklas en die potensiele risikoverskansing wat die bateklas bied. Regulasie 28 van die Pensioenfondswet vereis dat 'n maksimumtoewysing van vyf persent in ongenoteerde bates bele mag word en dit sluit privaataandele as 'n bateklas in. Een van die redes hoekom beleggers nie hierdie bateklas verstaan nie, is weens 'n gebrek aan vergelykbare data met die genoteerde bateklasse soos genoteerde aandele en genoteerde verbande. Uit hierdie bateklasse verkry mense inligting op 'n daaglikse basis en is hulle in staat om die daaglikse pryse en waardes van hul portefeuljes te verstaan. Hulle kan ook probeer om die afsonderlike gevolge binne hul portefeuljes te begryp deur veranderlikes soos prys inkomsteverhouding en dividendopbrengste te evalueer, soos wat die inligting beskikbaar raak. Hierdie navorsing poog om genoteerde privaataandeelmaatskappye te gebruik om 'n privaataandeelindeks daar te stel. Die maatstawwe wat gebruik word, is dieselfde as die wat Bilo, Christopbers, Degosciu en Zimmennann (2004) gebruik het toe bulle 'n Genoteerde Privaataandeel-indeks (GPA) daargestel bet, waarin 114 genoteerde privaataandeelmaatskappye wereldwyd uit hoofsaaklik Europa en Noord-Amerika gebruik is. Die Suid-Afrikaanse Indeks is saamgestel uit ses maatskappye en hoewel die steekproef klein blyk te wees, was die eindresultaat voldoende bevredigend om verdere navorsing volgens dieselfde riglyne te regverdig en om die notering van meer sulke maatskappye aan te moedig. Die indeks is vervolgens ontleed aan die hand van moderne portefeulje-ontledings tegnieke om die risiko en opbrengste van hierdie bateklas te verstaan en hoe dit reageer wanneer dit met ander bateklasse vermeng word. Die resultate dui daarop dat hierdie bateklas onvoldoende onderskryf is, maar dat daar 'n nodigheid bestaan om 'n meer verteenwoordigende indeks selfs op 'n interne opbrengskoers grondslag daar te stel.

Full textAbstract:
Les listes de rois, rédigées dans le haut Moyen Âge occidental, sont des documents chronologiques qui dressent les noms des souverains ayant régné sur un même peuple. Les chercheurs ont principalement étudié ces sources pour déterminer les durées des règnes des souverains mentionnés. Nous nous proposons d’étudier ces textes selon une double perspective philologique et historique. Notre réflexion est élaborée à partir de trois axes de recherche : la rédaction des listes, leurs diffusions et leurs usages. Ils permettent de déterminer les spécificités de cette forme d’écriture. Dans un premier temps, nous étudions trois cas de listes qui accompagnent des codes de lois du haut Moyen Âge : la liste des rois des Lombards et l’Édit de Rothari, la liste des rois des Wisigoths et le Liber Iudiciorum, la liste des rois des Francs et la Loi salique. Nous restituons les logiques qui président à la rédaction et à la diffusion de ces documents et, ainsi, montrons que la copie de ces textes, qui exposent un discours sur le passé royal d’un peuple, répond majoritairement à des enjeux politiques et idéologiques. Dans un second temps, nous proposons une synthèse à propos des listes de rois. Nous tentons de déterminer en quoi ces textes relèvent d’une part d’héritage de la culture écrite romaine. L’identification des auteurs des listes permette de souligner les rôles octroyés à ce document au moment de sa création et les méthodes employées lors de la mise en liste. Il apparaît que l’élaboration et la circulation de ces textes répondent autant à des usages pratiques qu’à des enjeux mémoriels et politiquesThe king-lists, written in the Early Western Middle Ages, are chronological documents that mention the name of the rulers that ruled over the same people. The researchers mainly studied these sources to determine the duration of those rulers’ reigns. We propose to study these texts from both a philological and historical perspective. Our thinking is based on three areas of research : the drafting of lists, their distribution and their use. It makes possible to determine the features of this form of writing. First of all, we study three cases of lists that go with civil codes laws from the Early Middle Ages: the list of Lombard kings and the Edict of Rothari, the list of Visigoth kings and the Liber Iudiciorum, the list of Frankish kings and the Lex salica. We explain why and how theses documents are written and disseminated and, from that, we show that the copying of these texts, which express an intention about the royal past of a people, meets both political and ideological issues. In a second step, we propose a synthesis about the king-lists. We try to determine why these texts are part of the Roman written cultural heritage. The identification of their authors makes it possible to highlight the roles assigned to this document at the time of its creation and the methods used during the listing. It appears that the elaboration and circulation of theses are for practical uses as well as memory and political issues

Full textAbstract:
The Enron collapse in 2001 has resulted in an increasing attention to corporate governance. Even in Sweden, some scandals have occurred, for example Skandia, ABB, Trustor; a parallel could be drawn, implying that these scandals have resulted in increased attention to corporate governance. Corporate governance concerns the relationship between a corporation’s management, board of directors, shareholders and other stakeholders. The problems with the relationship between managers and share-holders are referred to as the principle-agent problem. The increase in corporate governance disclosure can be seen as a way by the corporations to regain the trust from the shareholders. Can agency theory be used to explain why some corporation disclose more corporate governance information than others?
The purpose with this master thesis is, with starting point in agency theory, to contribute to the understanding of which factors that influence corporations to disclose corporate governance information in the annual reports.
For this thesis, a quantitative research has been performed. Annual reports from corporations listed on the Stockholm Stock Exchange have been examined, to be able to develop a corporate governance disclosure index and to measure 15 characteristics, derived from the agency theory and two control variables. The data was analysed in SPSS , using both linear and multiple regressions.
The analysis showed that role duality actually measured if a corporation had a foreign parent company and corporations listed on the O-list other on Stockholm Stock Exchange served as proxies for smaller corporations. Therefore, it was possible to con-clude that corporations were influenced by the origin of the parent company and the size of the corporation to disclose corporate governance information. Another conclusion was that corporate governance characteristics derived from agency theory is not appropriate when trying to find factors that influence corporations to disclose corporate governance information. Nevertheless, this does not mean that it is inappropriate to take the starting point in the agency theory.

Full textAbstract:
In the context of Listed Property Trusts (LPTs), three strategic investment issues have received considerable prominence in recent years. This thesis focuses on both the quantitative and qualitative aspects of these three strategic investment issues. 1/ the role of international property in LPTs 2/ the effect of stapled-securities management structure 3/ the performance of property securities funds. The three investment issues are assessed in some detail. The findings of the research suggest that the addition of international LPTs in the Australian LPT portfolio has resulted in significant diversification gains. The findings of the mixed-asset portfolio analysis suggest adding international LPTs to the Australian mixed-asset portfolio.Portfolio performance improved considerably. Mixed-asset portfolio performance is further enhanced when direct property is included. It is evident from the study that the property research discussed has led to the development of new LPT methodologies and a fuller understanding of the investment dynamics of the LPT sector in Australia.Doctor of Philosophy (PhD)

Gu, Wei. "Corporate governance of Chinese publicly listed companies." Thesis, University of Nottingham, 2013. http://eprints.nottingham.ac.uk/14411/.
Full textAbstract:
Agency theory suggests that problems will arise when there is a separation of ownership and control in firms. According to the literature, the main agency problem under a diffused ownership structure is likely to be the conflict of interests between managers and shareholders, whereas the central agency problem under a concentrated ownership structure is probably the exploitation of minority shareholders' interests by controlling shareholders. In the case of Chinese enterprises, such problems are even more complicated, as the government acts as both the regulator and player in the markets. This thesis utilises data from Chinese stock markets to address some important issues in the corporate governance literature. Firstly, it empirically examines the relationship between ownership structure and corporate performance in Chinese publicly listed companies (PLCs), with the heterogeneity amongst state ownership types being carefully explored. In contrast with previous research, I found that state ownership does not necessarily lead to inferior corporate performance, and some state owners can perform equally as well as their private competitors. Secondly, this thesis thoroughly investigates the issue of corporate cash holdings of Chinese PLCs, which enhances our understanding of firms' cash holding behaviour in the context of the largest transition economy. The empirical analysis not only reveals the determinants of corporate cash holdings of PLCs, but also I confirms the existence of the target cash holding level in China. Moreover, the exploitation of firms' dynamic adjustment mechanisms towards target levels is also included in the analysis. Finally, it seeks to redress the gap in the literature on top executive turnover in the Chinese context. The executive turnover-performance relationship is explicitly modelled in the analysis, and a variety of reasons why CEOs exit their posts are also dearly identified. Empirical findings confirm a negative relationship between corporate performance and CEO turnover. Also, empirical analysis suggests that regardless of the ownership types, there is no systematic difference in the CEO performance-turnover sensitivity among PLCs. Meanwhile, there is evidence showing that PLCs tend to report some 'face-saving' reasons instead of disclosing true reasons for turnovers, in order to protect their departing CEOs.
