Full textAbstract:
This thesis looks at the politics of transport in the Major era, arguing that transport has emerged as an issue of high political salience in the 1990s. In this period transport, and most particularly the motor car, increasingly came to be blamed for a combination of economic and environmental problems including rising congestion, noise, land-use impacts and a deterioration of air quality and traffic safety standards. The primary. aim of this thesis is to explain these developments and their effects by utilising agenda setting theory. This thesis argues that the operation of the agenda setting dynamic in the transport case illustrates aspects of a number of models of agenda setting. It looks at the role of actors, problems, external events and non-decision making and argues that, in part, they all make a useful contribution to the study of political change in the Major era. However, it also argues that different models of agenda setting apply in different circumstances and that a model which may provide a useful explanation of situation A may provide a less satisfactory explanation of situation B. The explanation for this is that transport is a multi-faceted issue which affects mobility, the environment, and economic development as well as issues of lifestyle and personal freedom; the priorities which central government attaches to transport policy outcomes reflect this diversity. These different aspects of the transport issue are affected by different agenda setting processes, depending on the extent to which they challenge the dominant policy imperatives of the state. For example, in a situation in which the policy imperatives of the state are threatened, the agenda setting process will be highly constrained and proponents of change, will find it very difficult, if not impossible, to alter the agenda. In such a case, the models of non-decision making will be an important, often the dominant, explanation of the agenda setting process. Overall, this study argues that the transport agenda setting process operates in, and is constrained by, a policy making environment which is dominated by the policy imperatives of the state.

Full textAbstract:
Even though enzymes tend to specialize on one reaction during evolution, enzyme promiscuity is an abundant phenomenon. The subject of this thesis is the Salmonella enterica N’-[(5’-phosphosoribosyl)-formimino]-5-aminoimidazole-4 carboxamide-ribonucleotide (ProFAR) isomerase (SeHisA), a (βα)8-barrel enzyme from the histidine biosynthesis that catalyzes one reaction on one substrate in one organism. In Actinobacteria HisA has evolved to a bifunctional enzyme called phosphoribosyl isomerase A (PriA): it is capable of catalyzing the reaction normally done by the N’-(5’-phosphoribosyl) anthranilate (PRA) isomerase (TrpF) as well. The functional plasticity of PriA is possible due to the common reaction mechanism of HisA and TrpF, called Amadori rearrangement. The Amadori rearrangement is an acid-base catalyzed isomerization reaction where the aminoaldose (ProFAR or PRA) is converted into the corresponding ketose (PRFAR or CdRP). A SeHisA mutant with a glutamine to arginine mutation in position 18 (Q18R) shows a detectable TrpF activity, whereas another mutant with a duplication of residues from 13 to 15 (dup13-15) loses its HisA activity and gains TrpF activity. My first aim was to improve the TrpF activity of the Q18R mutant. A G79S mutation was introduced inspired by PriA. Proteins were purified and crystallized. In order to gain complex structures with either the TrpF reaction product analogue reduced CdRP (rCdRP) or ProFAR, co-crystallization and soaking were done. ProFAR is not commercially available and had to be synthetized and purified. In vitro TrpF activities of the Q18R and Q18R/G79S mutants were measured. My second aim was to compare the Q18R mutant with the dup13-15 mutant, since there is very little structural difference between them, but they show high difference in catalytic activity. Mutants, which would bridge the functional gap between them, were designed and by using lambda red recombineering were introduced into a Salmonella typhimurium genome. In vivo growth rate was measured and relative fitness was calculated for each mutant in respect to their HisA and TrpF activity. HisA mutants Q18R and Q18R/G79S showed very poor TrpF activity in in vitro assays. No dissociation constants could be measured for either of the mutants using microscale thermophoresis, and a very low kcat/KM value (~2 s-1M-1) with a high error rate could be determined for Q18R/G79S. Complex structures of Q18R and Q18R/G79S mutants with ProFAR were solved at a 2.47 Å and a 1.78 Å, respectively, from soaked crystals. No structure with rCdRP was obtained. Growth rate measurements in comparison with a strain with wild type HisA and TrpF, gave striking results pointing out the important role of the residue in the position 16 when three residues are inserted after the arginine in position 18. A leucine in position 16 yielded wild type HisA activity (94%) and poor TrpF activity (0-5%), with a valine, no HisA activity (0%) and a moderate TrpF activity (38-46%) were found compared to the wild type. These results pointed out how small the barrier between a specialist, a promiscuous and a bifunctional enzyme can be. SeHisA, being a specialized enzyme can easily be modified in order to gain TrpF function, and as I have showed in the present study, a single methyl group (the difference between a leucine and a valine) can turn the activity of an enzyme inside out.

Full textAbstract:
Major depressive disorder (MDD) is highly recurrent. Researchers have proposed that certain traits predispose people to repeated episodes of this disorder. The current study examined the hypothesis that maladaptive emotional responding to stimuli would predict a worse depression outcome over six months. Participants were 58 individuals--18 controls, 22 individuals with MDD, and 18 individuals with minor depression (mD; subthreshold depression)--who participated in a diagnostic interview and emotion-modulated startle procedure at time one, and who returned for a second diagnostic interview six months later at time two. An identical emotion-modulated startle procedure was then repeated at time two with 33 individuals--12 controls, 14 individuals with MDD, and 7 individuals with mD. Startle probes were presented during unpleasant, neutral, and pleasant pictures, as well as during inter-trial intervals (ITI) in the absence of pictures. We used eye-blink startle responses to predict the time two level of depression severity and the likelihood of depression recurrence. Time one startle in the context of neutral pictures predicted depression outcomes at time two, such that larger time one startle responses during neutral pictures were associated with the presence of a time two depressive episode and higher time two self-report scores of depression severity (Beck Depression Scale scores). In addition, startle responses during ITIs (occurring in the absence of pictures) also predicted depression outcome, but in the opposite direction. Specifically, larger time one startle responses during ITIs were associated with better time two depression outcomes. We discuss the implications of these results.

Full textAbstract:
This thesis focuses on Mean Field Game (MFG) theory with applications to consensus, flocking, leader-follower and major-minor agent systems. The MFG methodology addresses a class of dynamic games with a large number of minor agents in which each agent interacts with the average or so-called mean field effect of other agents via couplings in their individual dynamics and cost functions. A minor agent is an agent which, asymptotically as the population size goes to infinity, has a negligible influence on the overall system while the overall population's effect on it is significant. The thesis is presented in three main parts.The first part consists of applications of the MFG methodology to large population consensus and flocking behaviour. In these formulations each agent seeks to minimize its individual quadratic discounted or long time average (i.e., ergodic) cost functions involving the mean of the states of all other agents. The resulting MFG control strategies steer each agent's state toward the initial state population mean, and by applying these decentralized strategies, the system reaches mean-consensus asymptotically as time and population size go to infinity.The second part is concerned with the extension of the mean field linear-quadratic-Gaussian (MF LQG) framework so as to model the collective system dynamics which include large population of leaders and followers, and an unknown (to the followers) reference trajectory for the leaders. The cost of each leader is based on a trade-off between moving toward the reference trajectory and staying near leaders' own centroid. On the other hand, followers react by tracking a convex combination of their own centroid and the centroid of the leaders. The MF LQG equations characterizing the Nash equilibrium for infinite population systems are derived, and under appropriate conditions, they have a unique solution leading to decentralized control laws. The computation of the followers' mean field control laws requires knowledge of the complete reference trajectory which is in general not known to the followers but is estimated by a likelihood ratio based adaptation scheme based on noisy observations taken by the followers on a random sample of leaders. The final part focuses on large population dynamic games with nonlinear stochastic dynamical systems involving agents of the following mixed types: (i) a major agent, and (ii) a large population of minor agents. The major and minor agents are coupled via both: (i) their individual nonlinear stochastic dynamics of controlled McKean-Vlasov type, and (ii) their individual finite time horizon nonlinear cost functions. A distinct feature of MFG problems with mixed agents is that even asymptotically (as the population size approaches infinity) the noise process of the major agent causes random fluctuation of the mean field behaviour of the minor agents. To deal with this, a stochastic mean field system is formulated in contrast to the deterministic mean field system employed in standard MFG problems.Cette thèse se concentre sur la théorie des jeux à population importante (en Anglais, Mean Field Games (MFG)) avec des applications aux systèms de consensus, flocage, chef-suiveur et aux systèmes d'agents majeure-mineure. La méthodologie MFG aborde une classe de jeux dynamiques avec un grand nombre d'agents mineures dans laquelle chaque agent interagit avec l'effet du champ moyen des autres agents par l'intermédiaire d'accouplements dans leurs dynamiques individuelles et des fonctions de coût. Un agent mineur est un agent qui a une influence négligeable sur l'ensemble du système, mais sur lequel la population globale a un effet significatif. Cette thèse est présentée en trois parties principales. La première partie developpe des applications de la méthodologie MFG au consensus d'une population importante et le comportement de flocage. Dans ces formulations, chaque agent cherche à minimiser ses coûts quadratiques individuels, soit escomptés, soit moyennés en temps (c'est-à-dire ergodique), impliquant la moyenne des états de tous les autres agents. Les stratégies résultant de contrôle MFG orientent l'état de chaque agent vers la moyenne de la population initiale, et en appliquant ces stratégies décentraliseés, le systéme atteint un consensus moyen asymptotiquement en temps et en population. La deuxième partie s'intéresse à l'extension du cadre des jeux à population importante linéaire-quadratique-Gaussienne (MF LQG) pour modéliser la dynamique du système collective qui comprennent une grande population de chefs et de suiveurs, et une trajectoire de référence pour les chefs qui est inconnue aux suiveurs. Le coût de chaque chef est basé sur un compromis entre le déplacement vers la trajectoire de référence et de rester près du centre de gravité propre des chefs. D'autre part, les suiveurs réagissent en faisant le suivi d'une combinaison convexe de leur centre de gravité propre et celui des chefs. Les équations MF LQG qui caractérisent l'équilibre de Nash pour les systèmes de population infinie sont dérivées, et, étant donnédes conditions appropriées, ils ont des solutions uniques qui menent aux lois de contrôle décentralisées. Les calculs des lois de contrôle MFG des suiveurs nécessitent la connaissance complète de la trajectoire de référence qui n'est pas généralement connue aux suiveurs, mais qui est estimée par un rapport de vraisemblance, basé sur des observations bruitées d'un échantillon aléatoire des chefs. La dernière partie se concentre sur les jeux dynamiques des populations importantes avec des systèmes dynamiques stochastiques non-linéaires impliquant des agents mixtes suivants: (i) un agent majeur, et (ii) une grande population d'agents mineurs. Les agents majeurs et mineurs sont couplés par ces deux: (i) leurs propres dynamiques stochastiques non-linéaires et contrôlées de type McKean-Vlasov, et (ii) leurs fonctions de coûts individuelles non-linéaires à horizon de temps fini. Une caractéristique distincte des problèmes MFG avec des agents mixtes est que, même asymptotiquement (lorsque la taille de la population tend vers l'infini), le processus de bruit de l'agent majeur provoque une fluctuation aléatoire du comportement du champ moyen des agents mineurs. Pour faire face à cela, un système stochastique à champ moyen est introduite comme extension du système déterministe de champ moyen des problèmes de MFG standard.

Walker, Stephen. "Major and minor architectural issues in the work of Gordon Matta-Clark." Thesis, University of Sheffield, 2008. http://etheses.whiterose.ac.uk/6103/.
Full textAbstract:
This thesis explores a range of architectural issues that are raised by the oeuvre of the artist Gordon Matta-Clark (1943-1978). In particular, it examines the ways in which his oeuvre might expand our understanding of the central tenets of architectural modernism, and valorise some issues that modernism downplays or denies. The thesis developed as a response to an awkwardness observed around the reception by both architects and the art world of Matta-Clark's work. It proposes that recent changes in this reception have involved the erasure rather than the acknowledgement of the causes of such awkwardness. In contrast to this general tendency, the thesis suggests that these causes are significant, and that for architecture in particular they provide a resource that can raise a number of important questions for the contemporary situation.

Franklin, Sebastian. "The major and the minor on political aesthetics in the control society." Thesis, University of Sussex, 2010. http://sro.sussex.ac.uk/id/eprint/2372/.
Full textAbstract:
This thesis examines the crucial diagnostic and productive roles that the concepts of minor and major practice, two interrelated modes of cultural production set out by Gilles Deleuze and Félix Guattari in Kafka: toward a Minor Literature (1975), have to play in the present era of ubiquitous digital technology and informatics that Deleuze himself has influentially described as the control society. In first establishing the conditions of majority and majority, Deleuze and Guattari's historical focus in Kafka is the early twentieth century period of Franz Kafka's writing, a period which, for Deleuze, marks the start of a transition between two types of society – the disciplinary society described by Michel Foucault in Discipline and Punish and the control society that is set apart by its distribution, indifferent technical processes and the replacement of the individual with the dividual in social and political thought. Because of their unique conceptual location, at the transition between societies, the concepts of majority and minority present an essential framework for understanding the impact of ubiquitous digital technology and informatics on cultural production in the twentieth century and beyond. In order to determine the conditions of contemporary major and minor practice across the transition from disciplinary to control societies, the thesis is comprised of two interconnecting threads corresponding to majority and minority respectively. Drawing on the theoretical work of Deleuze and Guattari, Friedrich Kittler and Fredric Jameson alongside pioneering figures in the historical development of computation and informatics (Alan Turing, Claude Shannon and others), material observation on the technical function of digital machines, and the close examination of emblematic cultural forms, I determine the specific conditions of majority that emerge through the development of the contemporary control era. Alongside this delineation of the conditions of majority I examine the prospective tactics, corresponding to the characteristics of minority set out by Deleuze and Guattari in Kafka, which emerge as a contemporary counter-practice within the control-era. This is carried out through the close observation of key examples of cultural production in the fields of literature, film, video, television and the videogame that manifest prospective tactics for a control-era minor practice within the overarching technical characteristics of the control-era major. Through an examination of these interrelated threads the thesis presents a framework for both addressing the significant political and cultural changes that ubiquitous computation effects in constituting the contemporary control society and determining the ways in which these changes can be addressed and countered through cultural production.

Full textAbstract:
The proposed ASTM procedures for the determination of 13 major and minor., and 11 trace elements, in solid coal and coke combustion residues by inductively coupled plasma-atomic emission spectrometry (ICP-AES) were checked for routine use. In this study, the ICP analysis values and XRF analysis values of major and minor elements in two kinds of coal and two kinds of limestone were compared. It was shown that over 95% closure of the mass balances of the 24 major, minor, and trace elements was obtained with the proposed ASTM procedure. Also, it was demonstrated that trace elements may be lost through combustion. From six combustion runs, the composition of the fly ashes produced in the FBC burns was determined by XRF analysis. The total carbon, inorganic carbon, and unburned carbon in the fly ashes were also determined. The combustion efficiency of the AFBC system was calculated by comparing the carbonto-iron ratios in the unburned fuel to that in the fly ashes.

Full textAbstract:
The purpose of this study was to determine the relationship between anxious/depressed and withdrawn symptoms and performance on a variety of cognitive and academic achievement measures. The sample included 343 subjects, drawn from a pool of subjects aged 6 to 11 years who were part of a sleep apnea study. A comprehensive battery of selected tests that measured cognitive and academic achievement function was administered to all sampled subjects. Parents of the subjects were given an instrument to complete in order to assess behavior function.The obtained data were analyzed by using Pearson Product Moment Correlation Coefficient analyses, T test procedures, and chi-square analyses. A significant negative correlation was found between anxious/depressed and withdrawn symptoms and the following cognitive and academic measures: general intelligence including verbal and nonverbal abilities, language, specific executive function skills, attention and processing speed, psychomotor speed and coordination with the dominant hand trial, and a subtest assessing math problem solving skills.There were statistically significant differences found between those subjects who obtained approaching borderline and clinically significant anxious/depressed, withdrawn, and both anxious/depressed and withdrawn symptoms on the following cognitive and academic measures: general intelligence including verbal and nonverbal abilities, language, specific executive function skills, attention and processing speed, psychomotor speed and coordination with the dominant hand, the interference and/or delayed recall trial of a memory task, and basic reading, math problem solving, and early spelling/writing skills.There was a significant difference found with regard to parent education level for children identified with withdrawn symptoms as compared to children without these symptoms but there were no other differences with regard to age, gender, ethnicity, or parent education level for children identified with anxious/depressed or withdrawn symptoms as compared to children without these symptoms. Additionally, Caucasian children performed significantly better than Hispanic children on a variety of the cognitive and academic measures.Overall, these findings support the hypotheses that depressive symptomatology does impact performance on cognitive and academic measures. Additionally, methodological problems for exercising caution in the interpretation of obtained findings were discussed. The implications of these findings for psychological practitioners, educators, and physicians were described.

Full textAbstract:
Incivility within organizations is a rampant problem with dire consequences,including adverse effects on both job satisfaction and psychological states. This study was conducted to address the gap in the current literature that looks at incivility within organizations. To date, no studies have assessed the impact of bottom-up incivility (i.e., incivility that is directed from subordinates to supervisors) on supervisor targets. Thus, this study investigated the impact of bottom-up forms of incivility of supervisors’ mental and physical states, as well as their levels of job satisfaction. However, due to small sample sizes, the current research was expanded to address the effects of both bottom-up incivility and other forms of incivility (i.e., peer-to-peer and superior-to-subordinate). As a result, the study consisted of two samples: bottom-up targets (N = 19) and targets of all forms of incivility (N = 89). In the bottom-up sample, results showed that instances of bottom-up incivility are a significant predictor of lower levels of job satisfaction. In the sample of targets of all forms of incivility, the results indicated that incivility was a significant predictor of lower levels of mental health. In the sample of targets of all forms of incivility, hierarchical regression analyses also showed that the effects of incivility on physical health were mediated by mental health.

Full textAbstract:
This thesis offers a reevaluation of selected short stories by Dorothy Parker. Although receptions of Parker's work have been predominantly negative, this is not seen as cause for lament, but rather for a revision of literary valuing practices and the canonical paradigms they support. Traditional assumptions about the status of so-called "minor" literature and its subservient relation to canonical works are rejected in favour of a revised appreciation of the qualities specific to minor modes of writing.

Resumo: Salmonella sp. é capaz de migrar para o interior da carne, sendo que as condições de estocagem e a presença de microbiota proteolítica podem influenciar nessa migração. No capítulo 1, realizou-se a pesquisa de Salmonella sp. em 21 peitos de frango, os quais foram segmentados em quatro partes, sendo elas pele, superfície, meio e interior. Subentendendo-se que a contaminação do frango ocorre na superfície, o estudo objetivou verificar a ocorrência de Salmonella sp. nos segmentos mais interiores do peito de frango e a possível influência de bactérias deterioradoras na presença de Salmonella sp. nesses segmentos. Como esperado, a porção com maior presença do patógeno foi a pele, seguida da superfície; os segmentos mais internos apresentaram uma porcentagem menor, porém foi detectada a bactéria. Não foi possível correlacionar a presença de bactérias deterioradoras com o aumento da prevalência de Salmonella sp. no interior da carne. No capítulo 2 objetivou-se avaliar a migração de Salmonella Enteritidis (SE) e Salmonella Heidelberg (SH) isoladas e adicionadas de psicrotróficos proteolíticos (SEP e SHP) para o interior de blocos de carne de frango submetidos a diferentes condições de estocagem: pelos tempos 6, 12, 24, 48 e 168 horas e nas temperaturas 2, 7 e - 30°C. Para quantificação bacteriana, as amostras foram divididas segmentos iguais, sendo o segmento A o mais superficial, B o intermediário e C o mais interno deles. Os resultados foram expressos em LogUFC/g e submetidos a análise de variância (ANOVA) e comparação de médias pelo teste de SNK. Salmonella sp teve êxito na migração pela carne frango em todas variações de tempo-temperatura e tratamentos, além disso, os dados sugerem que a migração foi progressiva até o tempo de 24h, porém decaiu com 48h. Em relação aos tratamentos, SEP teve contagens menores que os outros três tratamentos, os quais foram iguais entre si. Conclui-se que Salmonella sp. é capaz de migrar para o interior da carne em um curto período de tempo, mesmo em temperaturas de refrigeração, e que a presença de psicrotróficos proteolíticos teve efeito inibitório na migração do sorovar S. Enteritidis.
Abstract: Salmonella sp. is able to migrate into the meat, and the storage conditions as well the presence of proteolytic microflora may influence this migration. In Chapter 1, has been realized the research with Salmonella sp. using 21 chicken breasts, which were segmented into four pieces, which were: skin, surface, middle and interior. On supposing that the chicken's contamination occurs on the surface, the study aimed to verify the occurrence of Salmonella sp.in the innermost segments of the chicken breast and the possible influence of bacterial spoilage with the presence of Salmonella sp. in these segments. As expected, the portion with increased pathogen was skin, then the surface; the innermost segments showed a smaller percentage, but the bacterium was detected. It was not possible to correlate the presence of spoilage bacteria with increased prevalence of Salmonella sp. inside the meat. In chapter 2, one aimed to evaluate the migration of Salmonella Enteritidis (SE) and Salmonella Heidelberg (SH) isolated and added of proteolytic psychrotrophic (SEP and SHP) to the inside of chicken meat blocks under different storage conditions: to five periods of storage: 6, 12, 24, 48 and 168 hours and under temperatures of 2o, 7o and -30° C. For a bacterial quantitation, the samples were divided into equal segments, the segment A is the most superficial, segment B the intermediate and C the innermost of them. The results were expressed as logUFC/g and subjected to analysis of variance (ANOVA) and means were compared by SNK test. Salmonellasp succeeded by migration inside of chicken' meat in all variations of time-temperature and treatments and, in addition, the data suggest that the migration was growing gradually until 24 hours, but declined after 48 hours. In relation to treatments SEP had lower scores than the other three treatments which were equal among them. One may conclude that Salmonella sp. is able to migrate into the meat in a short period of time, even under refrigerated temperatures, and the presence of proteolytic psychrotrophic had inhibitory effect on the migration of serotype S. Enteritidis.

Full textAbstract:
Methods for the determination of inorganic constituents in coal fly ash by glow discharge spectrometry (GDS) and for the extraction of the organic compounds from coal and ash by supercritical fluid extraction (SFE) at temperatures below 150°C are reviewed. The inorganic elements studied included Al, Ca, C, Cu, Fe, Mg, Mn, P, S, Si and Ti. The organic compounds were measured by weight loss of the sample. The goal of this research was to find easier and faster ways to measure the concentration of inorganic elements in coal ash and to measure extractability of the coal itself, to make coal conversion and utilization more efficient and convenient. The results of this research indicated that for inorganic element determination, graphite can be used as the host material to make the coal ash pellets. When 90% graphite and 10% ash were mixed together and compressed under 20 tons of pressure, the pellets had suitable conductivity and mechanical strength, and the calibration curves for most of the elements were linear, especially for Al and Si. Copper was also used as the host material. In copper pellets the intensities of all elements were much larger than those in graphite, indicating that copper is more promising for pellet preparation. For supercritical fluid extraction, temperature is an important factor for extraction efficiency. The pressure and kinds of modifiers used were also important for extraction. The weight loss by supercritical fluid extraction of coal was much smaller than by soxhlet extraction, indicating that it is difficult to extract organic compounds from coal by SFE at temperatures below 150°C.

Full textAbstract:
Spider silk is one of the most remarkable materials produced in the natural world and its strength and extensibility are legendary. To date, the majority of studies have been performed on the following silks: dragline, capture spiral, and eggcase silk. The primary goal of this study was to characterize a lesser known silk type, called wrapping (swathing) silk, from Latrodectus hesperus. My research focused on elucidating the fibroins that make up the swathing silk. Perfonning MS/MS analyses on solubilized wrapping silk fibroins digested with trypsin, we demonstrate that a novel fibroin named AcSp !-like is present within wrapping silk. Consistent with this finding, SEM analyses reveal that wrapping silk is a composite material, containing at least three different diameter silk fibers. By using scanning electron micrographs, along with amino acid composition analyses and MS/MS analyses, we demonstrate wrapping material contains the fibroins AcSp1-like, MiSp1-like, MaSp1 and MaSp2. These are the first studies to reveal that minor, major and acinifonn silks are constituents of wrapping material.

Full textAbstract:
Methods for the simultaneous determination of major and minor constituents in cement and steel samples are developed in this thesis. The effect of matrix elements on analyte emission intensity has been evaluated. Dissolution procedures for these samples are based on the use of acids combined with a microwave-assisted digestion system and all measurements are then carried out by inductively coupled plasma atomic emission spectrometry. The previous methods of analysis for these samples has been reviewed. This section includes methods which are recommended by many authorities as Standard Procedures. It was found that the use of a microwave-assisted digestion system, coupled with inductively coupled plasma atomic emission spectrometry, reduced the total analysis time and reduced operating costs. The results obtained for the simultaneous elemental analysis of cement and steel using such methods are found to be in good agreement to the certified values. The methods developed offer the considerable advantages of rapid sample throughput, simplicity of use and are applicable for many routine analytical purposes.

The present study is part of a larger and ongoing research initiative investigating the cumulative cognitive effects of mild head injury in rugby union and focused specifically on high school rugby players. A comprehensive battery of neuropsychological tests was administered to top team high school rugby players (n = 47), and a non-contact sport control group of top team high school hockey players (n = 34). Direct comparisons of group mean scores and standard deviations across each neuropsychological test were carried out for the Total Rugby group versus the Total Hockey group as well as for the subgroups Rugby Forwards versus Rugby Backs. A correlational analysis was conducted to ascertain whether a relationship exists between the number of mild head injuries reported by the players and their cognitive test performance. Results of the group comparisons of means and variability on WMS Paired Associate Learning Hard Pairs - Delayed Recall provides tentative indications of the initial stages of diffuse damage associated with mild head injury in the rugby group and provides some evidence for impairment of verbal learning and memory in the Rugby Forwards group. The correlational analysis revealed no significant relationship between number of reported mild head injuries and cognitive performance. The findings and possible latent effects of the multiple mild head injuries reported by the rugby players are discussed in terms of brain reserve capacity theory and suggestions for future research are provided.

Full textAbstract:
The field of microfluidics has recently been gathering a lot of attention due to the enormous demand for devices that work in the micro scale. The problem facing many researchers and designers is the uncertainty in using macro scaled theory, as it seems in some situations they are incorrect. The general idea of this work was to decide whether or not the flow through micro diffusers and nozzles follow the same trends seen in macro scale theory. Four testing wafers were fabricated using PDMS soft lithography including 38 diffuser/nozzle channels a piece. Each nozzle and diffuser consisted of a throat dimension of 100μm x 50μm, leg lengths of 142μm, and half angles varying from 0o – 90o in increments of 5o. The flow speeds tested included throat Reynolds numbers of 8.9 – 89 in increments of 8.9 using distilled water as the fluid. The static pressure difference was measured from the entrance to the exit of both the diffusers and the nozzles and the collected data was plotted against a fully attached macro theory as well as Idelchik's approximations. Data for diffusers and nozzles up to HA = 50o hints at the idea that the flow is neither separating nor creating a vena contracta. In this region, static pressure recovery within diffuser flow is observed as less than macro theory would predict and the losses that occur within a nozzle are also less than macro theory would predict. Approaching a 50o HA and beyond shows evidence of unstable separation and vena contracta formation. In general, it appears that there is a micro scaled phenomenon happening in which flow gains available energy when the flow area is increased and looses available energy when the flow area decreases. These new micro scaled phenomenon observations seem to lead to a larger and smaller magnitude of pressure loss respectively.M.S.

Syftet med denna studie var att undersöka om det fanns en skillnad på studentens prestation i ett läsförståelsetest (TISUS), beroende på vilket tonläge (dur eller moll) på klassisk musik de fick lyssna på. Undersökningen genomfördes som ett laboratorieexperiment i en studierum på Karlstads Universitet, utifrån en oberoende mellan-grupps-design. Urvalet var ett tillfällighetsurval av studenter (N= 26), i åldrarna 19 – 33, inom Karlstads Universitet. Oberoende variabeln var klassiskt musik komponerad av Wolfgang Amadeus Mozart, vilket var uppdelat i de två olika betingelserna dur och moll. Beroende variabeln var studentens prestationsförmåga i läsförståelse. Deltagarna fick genomföra ett läsförståelsetest, bestående av tre texter med dess samtliga frågor att besvara på, samt bakgrundsfrågor och en utvärdering av experimentet. Resultatet visade att studenter som lyssnade på klassiskt musik, i tonläge dur, presterade bättre i läsförståelsetestet. Slutsatsen är att inverkan av tonlägena dur och moll skiljer sig på studentens prestationsförmåga i läsförståelse.The purpose of this study was to investigate whether there was a difference on the students’ performance in a reading comprehension test ( TISUS ), depending on the tone (major or minor) of the classical music they were listening to.The survey was conducted as a laboratory experiment in a study-room at the University of Karlstad, based on an independent between-group design. The selection was an opportunity sample of students (N = 26), between the ages 19-33, within the University of Karlstad. The independent variable was the classical music composed by Wolfgang Amadeus Mozart, which was divided into the two different tones, major and minor. The dependent variable was the student's performance in reading comprehension. The participants performed a reading comprehension test, consisting of three texts with all its questions to answer on, and background questions and an evaluation of the experiment. The results showed that students who listened to classical music, with the tone of major, performed better in the reading comprehension test. The conclusion is that the impact of the tones major and minor differs on the students’ performance in reading comprehension.

Full textAbstract:
Romano-British towns are conventionally divided into those that possessed administrative powers (the major or ‘public’ towns) and those that did not (the minor or ‘small towns’). Public towns and small towns differed in terms of size and socioeconomic status, with the latter sometimes characterised as semi-rural rather than truly urban. Hitherto, research into the differing nature of the communities at public and small towns has focused primarily on variations in settlement morphology, architecture and material culture. This study provides a new perspective on the issue by examining osteological indicators of lifestyle and health in skeletal samples from these two categories of site. Roman populations from the small town of Ancaster, Lincs (N=271) and the public town of Winchester, Hants (N=330) dating to c. AD 200-410 were analysed using standard osteological methods. Data on age-at-death, growth and stature, and skeletal and dental pathology were recorded and compared using a range of statistical tests to identify potential differences. Additionally, published data for contemporaneous populations were collated for comparison. A biocultural approach was used to contextualise the data with reference to archaeological and historical evidence. Some differences in demography were observed, but were probably the result of sample biases. No marked differences in growth or stature were observed. Pathology prevalence rates were comparable for many conditions. However, higher rates of joint disease at Ancaster, and differences in the pattern of long bone trauma may point to the Ancaster population having experienced a more agrarian lifestyle, engaging in more frequent and/or extended periods of heavy labour. In contrast, there was more evidence for violent trauma at Winchester, and the frequencies of three non-specific indicators of ill health (cribra orbitalia, porotic hyperostosis and dental enamel hypoplasia) and scurvy were higher. This suggests that people at Winchester experienced greater levels of social, dietary and environmental stress, perhaps reflecting a larger, more heterogeneous population. Dental health status was generally poorer at Ancaster, which may be due to differences in diet, oral hygiene and/or other non-dietary factors. Published data for other populations broadly support the study conclusions, although comparisons were limited by incompatibilities in methodology and data presentation. Overall, the findings corroborate existing perspectives on the socio-economic characters of public and small towns, but differences were not pronounced. The significance of the findings is discussed in relation to the nature of settlement and society in Roman Britain.

Full textAbstract:
PETRÓLEO BRASILEIRO S. A.A determinação de elementos traços em amostras de rocha por espectrometria de massas, combinada com ablação a laser (LA-ICPMS), tem se tornado uma importante ferramenta nas investigações em petrogênese, metalogênese e na prospecção de minérios. Apesar do surgimento de uma nova geração de lasers com menor duração de pulso (fs) e comprimento de onda (<266 nm), a calibração é ainda um ponto crítico, pois em geral, não há padrões disponíveis com matriz semelhante. Uma das interferências não espectrais mais relevantes em LA-ICPMS é o fracionamento químico, o qual acarreta diferenças entre as composições do alvo (padrão ou amostra) e da massa ablacionada, comprometendo a exatidão e a repetitividade dos resultados. Quando a análise integral é o objetivo principal, o assemelhamento de matriz pode ser alcançado por simples fusão das amostras e padrões em misturas de meta e tetraboratos, de modo similar ao que é feito, rotineiramente, na análise por fluorescência de raios-X (XRFA). Este trabalho relata metodologia para a determinação de elementos traços em amostras de basaltos, provenientes de sítios de exploração de petróleo. Os experimentos foram realizados com um sistema de ablação a laser CETAC LSX-100 em combinação com um espectrômetro ELAN 5000 ICPMS. Uma mistura de argônio-nitrogênio (2 % N2, 98 % Ar) foi utilizada como gás carreador, com o intuito de aumentar a massa ablacionada, e consequentemente, melhorar as intensidades de sinal e reduzir os limites de detecção. Conectou-se uma câmara ciclônica antes da tocha do ICP, com o objetivo de uniformizar o tamanho das partículas de aerossol, e deste modo, melhorar a repetitividade da medição e a robustez do plasma. A título de comparação, análises também foram feitas sem o emprego desta câmara. Padrões de calibração foram preparados a partir de dois materiais de referência certificados, o basalto NIST SRM 688 e a obsidiana NIST SRM 278. Os padrões de rochas pulverizadas foram misturados e homogeneizados com fundente de borato de lítio (CLAISSE, puro, 75 % Li2B4O7, 25 % LiBO2) nas proporções mássicas de rocha: fundente de 1:5, 1:11, 1:23, 1:47, respectivamente, obtendose, deste modo, cada padrão em quatro diferentes concentrações. O padrão interno escolhido foi o In, tendo sido este adicionado antes da fusão, resultando em alvos com a concentração de 100 mg kg(-1) neste elemento. Obtiveram-se os brancos, de modo similar, usando o fundente borato de lítio. A validação metodológica foi feita empregando-se o basalto (GSJ, JB-2) e o granito (NIMG, SARM-1), tendo sido a partir destes, preparados vidros com a proporção mássica (amostra: fundente) de 1:5 e contendo o padrão interno. Todas as fusões foram feitas em um forno de fusão automático (CLAISSE Fluxy). Análises por ICPMS e ICP OES foram feitas após dissolução de fragmentos dos alvos em HNO3, para verificação de possíveis perdas de elementos voláteis. Quarenta elementos foram determinados, a maioria das curvas de calibração apresentou coeficiente de determinação (R2) maiores que 0,995. Limites de detecção variaram de 0,013 mg kg(-1) para Tb, até 0,6 mg kg(-1) para Zn. Estes valores foram melhorados para vários elementos pelo uso da câmara ciclônica (V, Zn, Rb, Y, Nb, Ba, Ce, Sm, Tb, Dy, Ho, Tm). Nas análises do basalto (GSJ, JB-2) e do granito (NIMG, SARM-1), a exatidão foi melhor do que 5 % para V, Sr, Y, Ba, Ce, Nd, Yb e Lu; entre 5-10 % para: Sc, Zn, Rb, Tm, e de 10-20 % para: Co, Zr, La e Tb. A repetitividade foi melhor do que 5% para V, Rb, Sr, La, Nd, Ta; entre 5-10 % para: Sc, Co, Zn, Sr, Y, Zr, Ba, Tb, Yb; e de 10-20 % para: Ce, Tm, Lu e Hf. Foi utilizado ainda o método semiquantitativo TotalQuant II o qual, dentro da incerteza esperada para este tipo de calibração (cerca de 10 % a 20 %), forneceu resultados concordantes com calibração externa quantitat
Determination of trace elements in rock samples by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) has become an important tool for investigations in petrogenesis, metallogenesis and ore prospecting. However, despite the availability of new generation lasers with shorter pulse duration (fs) and wave length (<266 nm), calibration remains still a critical issue when matrixmatched standards are not available. One of the most serious non- spectral interference in LA-ICPMS is chemical fractionation, which causes compositions of standard and sample and their respective ablated masses to be different, thus compromising accuracy and precision of the results. When bulk analysis is the main objective, matrix matching can be achieved by the simple fusion of samples and standards with meta/tetraborates fluxes, similar to what is routinely used in XRFA. This work reports on our experience with this procedure in the analysis of basaltic rocks, aiming at the trace element characterization of host rocks from oil exploration sites in Brazil. The experiments were performed with a CETAC LSX- 100 laser ablation system (Nd:YAG, 266 nm, operated in the Q-switched and scanning mode) coupled to an ELAN 5000 ICPMS. An argon- nitrogen mixture (2 % N2, 98 % Ar) was used as carrier gas to enhance the mass of material ablated, thus increasing signal intensities and reducing detection limits. A cyclonic spray chamber was arranged just before the ICP-torch as a tentative to uniform aerosol particle size for improving measurement repeatability and robustness of the plasma. For comparison, the system was also operated without a spray chamber. Calibration samples were prepared from two standard reference materials: NIST SRM 688 basalt and NIST SRM 278 obsidian. The powdered rock standards were mixed and homogenized with a lithium borate flux (CLAISSE, pure, 75 % Li2B4O7, 25 % LiBO2) using rock-to-flux mass ratios of 1:5, 1:11, 1:23 and 1:47, respectively, thus obtaining each standard in four different analyte concentrations. Indium was used as an internal standard (IS) and was added before fusion to achieve targets with IS concentration of 100 mg kg(-1). Blanks from the lithium borate flux were produced in a similar way. Method validation was performed with GSJ basalt JB-2 and NIMG granite SARM-1, prepared at a constant sampleto- flux mass ratio of 1L:5 and containing also the IS. All fusions were performed in an automated furnace (CLAISSE Fluxy). Solution nebulization ICP-MS/OES after dissolution of smaller target pieces in HNO3 was used to assess for volatilization losses. Forty elements were determined and good linearity of the calibration curves was obtained and for most of them the correlation coefficient (R2) was higher than 0.995. Detection limits ranged from 0.013 mg kg(-1) for Tb to 0.6 mg kg(-1) for Zn, and improved for several elements by using a cyclonic spray chamber (e.g. V, Zn, Rb, Y, Nb, Ba, Ce, Sm, Tb, Dy, Ho, Tm). In the analysis of GSJ basalt JB-2 and NIMG granite SARM-1, accuracy was better than 5 % for: V, Sr, Y, Ba, Ce, Nd, Yb, and Lu; between 5-10 % for: Sc, Zn, Rb, Tm, and 10-20 % for: Co, Zr, La and Tb. Repeatability was better than 5 % for: V, Rb, Sr, La, Nd, Ta, between 5-10% for: Sc, Co, Zn, Y, Zr, Ba, Tb, Yb, and 10-20 % for: Ce, Tm, Lu and Hf. Additionally, the semiquantitative TotalQuant II calibration was applied, which gave, within the expected uncertainty for this calibration method (10 % to 20 %), concordant results when compared to the quantitative external calibration procedure. Preliminary results on the application of these methods for the determination of trace elements in basaltic host rocks from oil exploration sites will be shown.

Full textAbstract:
The context of this research is in support of autonomy for the elderly and includes the opportunity to use new technology, specifically a medium-size mobile robot employed as a telepresence platform allowing remote users to move, see, hear, and interact with patients at their homes. This new technology requires the development of an information system that will serve the overall care and help optimize the relationship between care and the elderly patient. To accomplish this, health informatics requires an integrative methodology to effectively combine different stakeholder perspectives into a fully functional information system.The principal objective of this research is to develop architecture for a teleoperated mobile robotic information system in the home health care context. A secondary objective will be to help evolve this newly designed methodological process into a more generalized methodology, applicable to other health care applications. This validation is undertaken by evaluating the transferability of the methodology utilised in the previous context by applying it to the design of an outpatient oncology clinic.The methodology is based on a descriptive business process analysis incorporating the Zachman Framework, validation iterations, and a method to develop system architecture. Applying this methodology to the teleoperated mobile robot yields a solid, integrative architecture consisting of ten use-case models.The net result of this endeavour is the specification of three interfaces: Health, Electronic Health Record and Teleoperation.

Full textAbstract:
Bibliography: pages 200-204.A low dilution fusion technique using a 2:1 flux:sample ratio has been developed for the accurate determination of major, minor and trace elements by x-ray fluorescence spectrometry (XRFS). This method has been used to analyze geological samples of widely varying and unusual composition such as lamproites and kimberlites. The results are shown to be of comparable if not better accuracy than other methods of sample preparation for XRFS. Analytical conditions, including corrections for spectral line interferences are reported for all the elements determined. For major element analysis three methods of calculating appropriate alpha coefficients were investigated, namely (1) multiple regression analysis, (2) Norrish and Hutton method and (3) a computer program, NBSGSC, involving fundamental parameters and the COLA equation. Methods (1) and (2) gave poor results for rock types of widely varying composition. The third method requires that the variation of alpha coefficients with varying weight fraction of the analyte element be taken into account when calculating alpha coefficients if accurate values for major and minor elements are to be obtained on low dilution fusion discs. For trace element analysis the average relative error was less than 5% and there was a decrease in sensitivity by about a factor of 2 compared with XRFS determinations on powder pellets. The elimination of particle size effects in the homogeneous glass fusion discs is a major advantage over the use of powder pellets, especially for the determination of elements such as Ba, Cr and the REEs. A loss on fusion technique has been employed to ensure complete loss of volatiles from the rock samples. Data presented highlight the problems encountered in the determination of the volatile content in geological samples. The oxidation and retention of sulphur in the discs was also investigated.

This thesis seeks to cut through the hype by measuring the precise extent of online campaigning by electoral candidates during the 2010 general election campaign. It does so by using an original and extensive dataset that captured personal website adoption and the use and content of social media and email. Data was collected directly from the websites and Web 2.0 tools used by candidates during the campaign and from a quasi-experimental email study involving contacting candidates. By assessing online campaigning from an elite perspective the thesis can engage with key debates prominent in the literature on online campaigning. The thesis poses three questions. The first question asks whether the Internet has become a mainstream campaigning tool for electoral candidates in the UK. The second question focuses on whether the Internet is allowing minor parties to compete on a more equal footing campaign-wise with their major counterparts, which feeds into the debates concerning normalisation or equalisation between competing political parties and candidates. The third question relates to the content of the online campaigns of candidates, and whether the Internet may be changing campaign styles in terms of moving them from a top-down ‘broadcast’ mass mobilisation model towards a more interactive and engaged form of campaign communication. The findings suggest that although social media was not used widely, personal websites and email use were relatively common. In assessing inter-party competition in online campaigns the thesis finds that although candidates standing for larger parties were more likely to have personal campaign websites, the other online campaign tools assessed here, social media and email, were found to be more equalised on some measures between candidates from major and minor parties. Finally, when assessing the content of social media and email use by candidates, the evidence suggests that online tools may be facilitating a move towards more open and engaged campaign communication. Broadcast mode social media campaigning, where candidates did not accept or respond to comments, was relatively rare. Moreover, candidates who did reply to the hypothetical voters email tended to provide personalised and engaged content rather than solely electioneering. Overall, the findings suggest that although online campaign tools have not thus far led to a huge change in campaign communications, it is leading to a small shift towards more equalised and engaged campaigning.
