Liddy, Nathaniel. "Molecular engineering of high affinity T-cell receptors for bispecific therapeutics." Thesis, Cardiff University, 2013. http://orca.cf.ac.uk/47271/.
Full textAbstract:
Cytotoxic T lymphocytes are able to identify malignant cells by scanning for aberrant peptides presented on cell surface human leukocyte antigen (HLA) Class I molecules by virtue of an antigen binding receptor called the T-cell receptor (TCR). Peptides presented by HLA Class I complexes represent the largest array of tumour associated antigens (TAAs) and are therefore ideal targets for immunotherapeutic reagents. Cancer patients frequently mount T-cell responses to tumour-specific antigens, but these are in most cases ineffective at clearing the tumour. This is in part due to the low affinity of TCRs for self-antigens coupled with low-level expression of target peptides on the surface of cancer cells. To harness the exquisite antigen recognition property of TCRs for use as potential therapeutic proteins, the principal goal of this thesis was to generate ultra-high affinity TCRs against three clinically relevant HLA Class I melanoma-specific epitopes, including peptides derived from Melan-A/MART-1(26-35), gp100(280-288) and MAGE-A3(168-176). TCRs are membrane-bound disulphide (ds)-linked heterodimers consisting of an alpha and a beta chain. Each chain comprises three hypervariable or complementarity-determining region (CDR) loops, which assemble to form the antigen binding domains. As a general rule the CDR3 loops, and to a lesser extent the CDR1 loops, contact the peptide bound in the HLA groove and as such specificity is largely attributable to the CDR3 loops. The remaining CDR loops interact with the HLA surface and not the bound peptide. Each CDR loop was mutagenised using degenerative NNK oligonucleotides and expressed on the surface of bacteriophage as fusions to the phage coat protein pIII. Through a Darwinian process of in vitro evolution using pHLA ligand as the target molecule, mutated TCRs with improved affinity for pHLA were identified. TCRs engineered by phage display were produced as soluble ds-linked proteins and the contribution to affinity of each mutated CDR was measured by surface plasmon resonance (SPR). Using a combinatorial strategy, individual mutated CDRs were spliced into the same TCR molecule in a stepwise manner to further increase binding affinity. The final combination of mutated CDRs was shown to bind their cognate pHLA antigen with substantially improved KD values of 18 pM (Melan-A/MART-1(26-35)), 11 pM (gp100(280-288)) and 58 pM (MAGE-A3(168-176)), representing an increase over the wild-type TCR of approximately 1.8 million-fold, 1.7 million-fold and 3.7 million-fold respectively. In addition, having discovered an off-target binding profile for the high affinity MAGE-A3 TCR, the phage display methodologies were explored to 5 reestablish the specificity of this molecule. These results are significant because this has provided a platform on which, for the first time, to make TCR-based therapeutics. For example, the affinity enhanced gp100 TCR is currently undergoing clinical evaluation in a Phase I/II trial.

Roberts, Phillip. "Cinema and control." Thesis, Cardiff University, 2013. http://orca.cf.ac.uk/47272/.
Full textAbstract:
This thesis explores the political implications of Gilles Deleuze's two-volume work on the cinema (Cinema 1: The Movement-Image [2005a] and Cinema 2: The Time-Image [2005b]). I argue that counter to the common reading of these works as being primarily concerned with aesthetics and philosophy, Deleuze's cinema books should be understood as a political critique of the operations of cinema. I outline the main arguments set out by these works as a political formulation and argue that they should be directly related to Deleuze's more explicitly political writings. In particular, I argue that these books should be read alongside Deleuze's later 'Postscript on the Societies of Control' (1992), which re-addresses some of the most significant aspects of his earlier work on cinema following a transforation in media technologies and social organisation. I argue that Deleuze's time-image and his later conceptualisation of control should be understood as forming the two poles of his theorisation of cinema and visual culture. When addressed as connected concepts, a significant political dimension emerges in this area of Deleuze's thought, focusing on a time-image that opens a range of possibilities for the future ordering of the world and a system of control that will recurrently close and eliminate these possibilities. Through a series of studies of film texts I will develop the political implications of Deleuze's thinking on cinema and visual culture in order ot show how the forces of control and the time-image operate and how these concepts can be systematised and further integrated into Deleuze's wider political thought.

Davis, Ben. "Stochastic epidemic models on random networks : casual contacts, clustering and vaccination." Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/47272/.
Full textAbstract:
There has been considerable recent interest in models for epidemics on networks describing social contacts. This thesis considers a stochastic SIR (Susceptible - Infective - Removed) model for the spread of an epidemic among a population of individuals, with a random network of social contacts, that is partitioned into households and in which individuals also make casual contacts, i.e. with people chosen uniformly at random from the population. The behaviour of the model as the population tends to infinity is investigated. A threshold parameter that governs whether or not the epidemic with an initial infective can become established is obtained, as is the probability that such an outbreak occurs and, if so, how large it will become. The behaviour of this model is then compared to that of a finite population using Monte Carlo simulations. The effect of the different transmission routes on the final outcome of an epidemic and the effect of introducing social contacts and clustering to the network on the performance of various vaccination strategies are also investigated.

Jeschke, Michael. "Heterophase triblock copolymer networks." Thesis, Durham University, 1997. http://etheses.dur.ac.uk/4727/.
Full textAbstract:
The investigation of morphological properties of linear triblock copolymers in the strong segregation limit has received much experimental and theoretical interest. Butadiene - Styrene - Butadiene (B-S-B) triblock copolymers have been compared to analogous cross-linked varieties using the techniques of small angle x-ray scattering (SAXS), solid state (^1)H NMR and stress-strain analysis. The properties being sought are; the dimensions of domains, the type of packing within copolymer systems, polystyrene : polybutadiene composition, and the mechanical properties of network systems. The evaluation of structural changes in the networks whilst the copolymer is continuously stretched is an important section of the project. A comparison of annealed and unannealed samples has been studied in each case. A comprehensive description of network mechanical properties has been accomplished by performing numerous force-elongation experiments on the materials. Parameters for the chemical cross-link density, physical entanglements, and network looseness have been extracted from force-elongation data using the Ball-Edwards slip-link model. The Mooney-Rivlin model and swelling data from the network systems have served as comparisons to the Ball-Edwards model. Details of the structural organisation in these systems have been determined using SAXS. The uncross-linked materials have been compared to the analogous networks and show that structural differences are present due to the effect of cross-linking altering the equilibrium structure. It has been demonstrated that stretching the network systems at room temperature induces variations in the domain distances from affine deformation. Domain distances have been determined for a set of lamellar morphology uncross- linked copolymers using solid-state (^1)H NMR experiments. The results obtained show a good agreement to SAXS data and theoretical predictions.

Al, Matrood W. A. A. "Factors that enhance the ability of Pseudomonas aeruginosa to resist the action of antibiotics." Thesis, Liverpool John Moores University, 2016. http://researchonline.ljmu.ac.uk/4727/.
Full textAbstract:
P.aeruginosa is one of the most important pathogens in nosocomial infections and fails to respond to standard treatment, particularly in the case of patients subjected to prolong antibiotic treatment. To generate a more comprehensive understanding of the failure of antimicrobial treatment, focusing especially on the adaptive resistance could be the key area that the bacterium develops in this phenomenon. Most studies on antibiotic resistance in P.aeruginosa have focused upon genotypic studies. This study set out to develop an in vitro model to examine the effect of continual exposure of P.aeruginosa PA01 to the antibiotics studied. Experiments were initially conducted to consider the factors that having a significant influence on antibiotic susceptibility using a novel fluorescence based assay (OxoPlate® system). P.aeruginosa was subjected to the action of tobramycin, amikacin and colistin under various environmental factors. The results of the in vitro analysis showed that, from among the three antibiotics used, amikacin was the antibiotic where resistance was most readily developed. From these results, chemostat studies were designed to examine prolonged exposure of the antibiotic to planktonic cells. Chemostat cultures were exposed to amikacin at sub-inhibitory concentrations using Evans defined synthetic medium at different dilution rates (D) under glucose limitation. Both cultures grown at 0.025h-1 and 0.06h-1 developed the following characteristics i. low-level amikacin resistance, which exhibited an increase in the MIC 4-fold. ii. a clear development of phenotypic resistance and this resistance was not acquired as evidenced by the loss of resistance on culture into fresh medium lacking antibiotic. iii. adaptive resistance to amikacin conferred low-level resistance to other aminoglycosides such as tobramycin and antibiotics with different modes of action such as colistin. Low oxygen availability was seen in the cultures grown at 0.099 h-1 and 0.125 h-1, which lead to i. the appearance of the so called “persister” phenotype. These persisters are sub populations of cells that showed a reduction in bacterial cell size as evidenced from the flow cytometry output as well as being slow growing and resistant ii. extracellular polymeric fibrils were produced in the cells derived after 72h incubation time. In all cases, continual exposure resulted in phenotypically distinct mucoid and non- mucoid colony morphotypes, which were clearly observed on amikacin-free nutrient agar. Some of these selected morphotypes showed from the MIC and MBC data a high-level resistance to the antibiotic when left without antibiotics. The biological responses resulting from these studies offer valuable clues underlying unsuccessful treatment. Conducting experiments using robust systems renders this project extremely novel in the field of microbiology and this will contribute to the development of viable treatment options and ultimately the reduction of the emergence of antibiotic resistance.

Almdni, Sabir M. Shakir. "Recombinant antibodies against Clostridium difficile toxin A." Thesis, University of Glasgow, 2013. http://theses.gla.ac.uk/4727/.
Full textAbstract:
Clostridium difficile is a major cause of nosocomial intestinal infection. The pathogen possesses two potent toxins, Toxin A and Toxin B, both of which contribute to diarrhoea, intestinal inflammation and tissue damage. Antibiotics are effective against the disease, however around 20 % of patients on treatment relapse after the termination of antibiotic therapy. The binding of Toxin A to a receptor on human intestinal epithelial cells initiates disease: this is considered the starting point from which the toxin elicits its effect. One feature of the carboxy-terminal domain of Toxin A is the presence of repeating units of amino acids that form a series of binding sites able to recognise disaccharides and trisaccharides on glycolipid and glycoprotein receptor molecules. Antibody response against the toxin can protect against C. difficile disease and efforts to generate vaccines have focused upon the carboxy-terminal, receptor binding domain. The aims of this project were to use phage display to isolate recombinant antibodies against those features of the carboxy-terminal domain of Toxin A thought to be responsible for receptor-binding and to assess if the antibodies were capable protecting against the action of Toxin A. Using published crystallographic data that has shown the interaction of Toxin A and trisaccharide, a region of about 113 amino acids from the carboxy-terminal region of Toxin A was expressed as a fusion to maltose-binding protein. The MBP fusion protein was expressed, purified on amylose resin, and characterised. The fusion protein was then used to isolate single chain antibodies from the Tomlinson libraries of scFvs, a synthetically diversified phage display library of single scaffold human antibodies. Conventional bio-panning methods were used in which the MBP fusion protein was bound to a plastic surface and the phage display libraries were pre-mixed with native MBP to inhibit the isolation of anti-MBP antibodies. Progressive enrichment of scFvs through 3 rounds of selection was observed. Those scFvs that showed strongest reaction against the target protein in ELISA but failed to react with native MBP were sequenced, expressed as soluble antibodies and purified on nickel chelating columns. While the resulting panel of scFvs showed similarities of sequence, none were identical. All were reactive with native, full-length Toxin A and appeared to bind to conformational (nonlinear) epitopes. Cross-reaction with Toxin B from C. difficile was also evident. A panel of truncation mutants were generated from the MBP fusion protein and using these in ELISA with the scFvs, reactivity appeared to be directed to features of a long repeat sequence of Toxin A. To assay whether the isolated scFvs possessed biological activity of significance, in vitro and in vivo protection assays were established. For experiments in vitro, the action of Toxin A upon cultured Vero cells was studied. Native Toxin A triggered a conversion of the cells from stellate to rounded morphology. When cells were exposed to 100 ng of toxin, this effect was evident within 60 minutes; at a 10-fold lower dose, the minimum quantity to which a response was detectable, virtually all cells had undergone rounding within 2 h. When individual scFvs were mixed with 10 ng of Toxin A prior to addition to Vero cells, there was a consistent delay in cytopathic activity that extended to 5 h. In this assay, the percentage of cells that had retained their stellate morphology 5 h post-challenge was dependent on the scFv used. To quantify the potency of this neutralising activity, the amount of each scFv required to achieve 50% protection during a 2 h challenge period was established. This revealed 3.5-fold difference between the most and the least effefctive scFv. The most potent scFv was used in an in vivo assay in which Toxin A was administered to the ligated intestinal loops of rats. Again, protective activity was evident. Overall, phage display technology enabled the assembly of a panel of scFv antibodies against the putative receptor binding site in the carboxy-terminal domain of Toxin A from C. difficile. The scFvs were able to protect against the cytopathic activity of Toxin A in vitro and in vivo and proposals are made about how these observations could be taken forward in a model of C. difficile infection that best mimics the human disease.

Ward, Lewis Henry. "Holocaust memory in contemporary narratives : towards a theory of transgenerational empathy." Thesis, University of Exeter, 2008. http://hdl.handle.net/10036/47273.
Full textAbstract:
What is the relationship between writing in the present and the traumatic historical events that form the subject of that writing? What narrative strategies do authors employ in order to negotiate the ethical and epistemological problems raised by this gap in time and experience? “Trauma theory” is undermined by clinical controversies and contradictory claims for “literal truth” and “incomprehensibility”. Similarly, the Holocaust has been considered inherently unrepresentable unless by those who witnessed it, leading to a false opposition between genres of “testimony” and “fiction”. A way out of these dead ends is to consider the role of the first-person narrator in contemporary Holocaust narratives. While use of this device risks an inappropriate level of identification with those whose experience is both extreme and unknowable, I argue that this problem may be resolved to an extent through “transgenerational empathy”, an approach to the past that is self-reflexive, incorporates ideas of time, memory and generations, and moves both towards and away from the victims of the past in a simultaneous gesture of proximity and distance. For this theory I draw on Dominick LaCapra’s definitions of empathy and “empathic unsettlement”, and on Hans-Georg Gadamer’s concept of the “fusion of horizons” between past and present. Transgenerational empathy involves giving equal weight to “memory” and “history”. An over-emphasis on memory leads to narratives that are merely identificatory, such as Anne Michaels’ Fugitive Pieces and Binjamin Wilkomirski’s Fragments. In contrast, W. G. Sebald’s use of a narrative persona in The Emigrants and Austerlitz enables transgenerational empathy in narrative by simultaneously imposing layers of distance while establishing close personal connection. Similarly, Jonathan Safran Foer’s third-generation aesthetic of “post-postmemory” in Everything is Illuminated uses a “dual persona” device to foreground empathically the abyss at the heart of any attempt to recapture the past. My analysis of these authors draws on the writings of Gillian Rose, Paul Ricoeur, Marianne Hirsch and Jacques Derrida. However, the concept of “transgenerational empathy” would benefit from further research, both in terms of its “temporal dimension” and the use of narrative personae by other contemporary authors such as Philip Roth.

Defesa: Curitiba, 15/02/2017<br>Inclui referências : f. 205-210<br>Resumo: Aquela que aparece, no catálogo oficial das obras de Villa-Lobos, como sua primeira composição para violão - a Suíte Popular Brasileira - veio a público apenas 1950, nos últimos anos da carreira do compositor. Esse conjunto de cinco peças, visto por muitos autores como uma homenagem de Villa-Lobos aos músicos populares do Rio de Janeiro, homenagem prestada no momento em que se acredita que o compositor vivia na companhia amistosa desses músicos, é observada, nessa dissertação, por outro prisma. Aqui, o lapso entre a suposta concepção da obra e sua publicação aparece como um testemunho da complexidade e da ambiguidade que permeia a relação de Villa-Lobos com a música popular e do modo como essa relação participa do sentido atribuído pelo compositor à sua vida. Observá-la por esse novo ângulo implicou em colocar em questão e análise: 1) os sustentáculos da interpretação que usualmente se faz do significado dessa obra, isto é, o lugar privilegiado que Villa-Lobos ocupa na memória musical do Brasil e os discursos musicológicos consolidados em torno dele; 2) o modo como Villa-Lobos construiu sua trajetória de vida no diálogo com a música popular e os rastros da Suíte Popular Brasileira que foram se sedimentando e adquirindo sentido ao longo de tal trajetória. As discussões e conclusões presentes nesta dissertação se baseiam numa pesquisa bibliográfica e documental acerca dos pontos mencionados; seu ponto de partida teórico pertence à Etnomusicologia, mas seu desenvolvimento não seria possível sem uma imersão em textos das ciências sociais, da história e da filosofia. Palavras-chave: Villa-Lobos. Suíte Popular Brasileira. Música popular. Música Erudita.<br>Abstract: The one that appears in Villa-Lobos's official catalog of works as his first composition for guitar - the Suíte Popular Brasileira - came to the public only in the 1950s, it is, in the last years of the composer's career. This set of five pieces, seen by many authors as a tribute by Villa-Lobos to the popular musicians of Rio de Janeiro, a tribute given at the time when it is believed that the composer lived in the friendly company of these musicians, is seen, in this dissertation, by another prism. Here, the gap between the supposed conception of the work and its publication appears as a testimony to the complexity and ambiguity that permeates Villa- Lobos's relationship with popular music and the way in which this relation participates in the sense attributed by the composer to his life. Observing it from this new angle implied putting into question and analysis: 1) the basis of the interpretation that is usually made of the meaning of this work, that is, the privileged place that Villa-Lobos occupies in the musical memory of Brazil and the musicological discourses consolidated around him; 2) how Villa-Lobos built his life trajectory in the dialogue with the popular music and the trails of the Suíte Popular Brasileira that were sedimenting and acquiring meaning throughout this trajectory. The discussions and conclusions present in this dissertation are based on a bibliographical and documentary research about the mentioned points. Its theoretical starting point belongs to Ethnomusicology, but its development would not be possible without an immersion in texts of the social sciences, history and philosophy.

Defesa: Curitiba, 07/03/2017<br>Inclui referências: 218-227<br>Resumo: O presente estudo teve como objetivo a construção e análise do panorama sobre as condições de qualidade de oferta do Ensino Fundamental no Brasil, com delimitação às informações das escolas de anos iniciais das redes municipais de ensino. A pesquisa optou pelo conceito de educação com qualidade social (DOURADO; OLIVEIRA; SANTOS, 2007; SILVA, 2009; ALMEIDA, 2004; DOURADO; OLIVEIRA, 2009), justificada pela abordagem dos fatores contextuais no processo de ensino aprendizagem como fundamentais para uma trajetória escolar de qualidade com equidade. A construção dessa dissertação teve como contexto de base a problematização do Estado Regulador e Avaliador, os limites do Ideb enquanto mensurador da qualidade educacional de um sistema/rede de ensino, além da descrição e diálogo teórico das variáveis e indicadores parciais da metodologia. O método de análise quantitativa empregada foi o Índice de Condições de Qualidade (ICQ), indicador construído em um programa de pesquisa desenvolvido no Núcleo de Políticas Educacionais da UFPR e descrito em Gouveia, Souza e Schneider (2011). A análise dos resultados do ICQ teve como ênfase os indicadores das redes municipais agregadas por estado, a construção de uma categorização com base nos dados trabalhados, denominada Nível de Condições de Qualidade (NCQ), além da análise panorâmica dos indicadores parciais que compõem o indicador de base, Índice de Condições do Professor (ICP), Índice de Condições Materiais da Escola (ICME) e Índice de Condições de Gestão (ICG), ambos fomentados pelos questionários de contexto das professoras, aplicadoras e diretoras das escolas que realizaram a edição de 2013 da Prova Brasil. As análises evidenciaram a desigualdade nas condições de oferta dos casos analisados e a relação direta de baixas (ou altas) condições de qualidade com sua localização estadual, caracterizando as redes municipais dos estados das regiões Norte e Nordeste com resultados inferiores às demais macrorregiões do Brasil. Apesar das condições de qualidade terem certa homogeneidade entre as redes municipais em cada estado, seus índices derivam de diferentes resultados de ICP e, principalmente, ICG e ICME. Consequentemente, ficou evidenciada a necessidade de ação da política educacional na forma de provimento das diretoras, existência e efetividade dos Conselhos de Escola, construção do Projeto Político Pedagógico de forma coletiva, maior investimento em condições materiais, de salários, formação inicial e realização de concursos para a carreira docente, principalmente nas redes municipais dos estados das regiões Nordeste e do Norte. A pesquisa é compreendida como ponto de partida para novos estudos, desde o aprofundamento qualitativo nas condições de qualidade mensuradas pelo ICQ até a expansão quantitativa aos anos finais do EF, condições de financiamento, estudo sobre desigualdades intraestaduais do ICG e do ICME e a exploração de fatores extraescolares, como condições socioeconômicas e culturais. Palavras Chave: Condições de Qualidade; Ensino Fundamental; Questionários de contexto; Prova Brasil; Políticas Educacionais.<br>Abstract; The purpose of this study was to construct and analysis an overview of the quality conditions of primary education in Brazil, delimiting of the information about early years' schools of municipal systems. The research opted for the concept of education with social quality, justified by the approach of the contextual factors in the educational process as fundamental for a qualitative school trajectory with equity. The construction of this dissertation was based on the problematization of the Regulating and Evaluator State, the limits of the Ideb as a measure of the educational quality, besides the description and theoretical dialogue of the variables and partial indicators of the methodology. The method of quantitative analysis used was the Quality Conditions Index (ICQ), an indicator built into a research program developed at the Center for Educational Policies at UFPR and described in Gouveia, Souza and Schneider (2011). The analysis of ICQ results focused on the indicators of the municipal educational systems aggregated by state, the construction of a categorization based on the data worked, called Quality Conditions Level (NCQ), in addition to the panoramic analysis of the partial indicators that make up the main indicator: Teaching Conditions Index (ICP), School Material Conditions Index (ICME) and School Administration Conditions Index (ICG), both of which were fomented by the context questionnaires applied in teachers, students and principals of the schools that carried out the edition of 2013 of the Prova Brasil. The analyzes showed the inequality in the supply conditions of the analyzed cases and the direct relationship of low (or high) quality conditions with their state location, characterizing the municipal systems of the states of the North and Northeast regions with results inferior than the other macro Brazilian regions. Although quality conditions have a certain homogeneity among the municipal educational systems in each state, their indexes derive from different results of ICP and, mainly, ICG and ICME. Consequently, it was evidenced the need for educational policy action in the form of directorial provision, existence and effectiveness of School Boards, construction of the Political Pedagogical Project in a collective way, greater investment in material conditions, salaries, initial training and public selection for teaching career, mainly in the municipal schools of the Northeast and North regions. This research is understood as a starting point for new studies, from the qualitative deepening of the quality conditions measured by the ICQ to the quantitative expansion to the other part of elementary school, financing conditions, study of ICS and ICME intrastate inequalities and exploration of off-school factors, such as socioeconomic and cultural conditions. Keywords: Quality Conditions; Elementary School; Context Questionnaires; Prova Brasil; Educational Policies.

Defesa: Curitiba, 13/09/2016<br>Inclui referências : f. 115-127<br>Resumo: O objetivo da pesquisa foi analisar por meio dos conceitos da psicologia analítica a experiência de ser mulher no kung fu, uma técnica de combate ancestral e viripotente que combina práticas físicas e espirituais. A amostra foi constituída por nove mulheres praticantes de kung fu com idades variadas entre vinte e um e trinta e oito anos, recrutadas mediante convite encaminhado para academias de kung fu em Curitiba e Região Metropolitana. Por tratar-se de uma pesquisa qualitativa, de natureza descritiva e hermenêutica, os dados foram coletados por meio de entrevistas de roteiro semiestruturado e organizados conforme o método fenomenológico empírico de A. Giorgi para a obtenção de unidades de significado, assim identificados: (1) "violência temida"; (2) "por que o kung fu?"; (3) "antes do kung fu"; (4) "durante o kung fu"; (5) "relações na academia"; (6) "como pensa ser vista"; (7) "ser mulher é ser alguém que..."; e (8) "contribuições do kung fu para a mulher". A dicotomia entre os sexos foi culturalmente valorizada pelas sociedades patriarcais e, de acordo com a visão junguiana ortodoxa, homens e mulheres biologicamente definidos possuem o tipo sexual oposto predominante em seus inconscientes classicamente denominados como os arquétipos de anima e animus, respectivamente. As análises das unidades de significado obtidas revelaram que a prática do kung fu, dentro da conjuntura social denominada de pós-moderna por filósofos contemporâneos, favoreceu àquelas mulheres uma gama de experiências que tem como produto uma ressignificação do seu papel de gênero. Esse novo patamar de compreensão corresponde à proposta pós-junguiana que desvincula de modo contundente o sexo biológico dos arquétipos anima e animus, ora compreendidos como sendo uma propriedade comum a homens e mulheres, melhor representados pela notação "anima/us". Conclui-se que o kung fu, como lócus físico e psíquico de experiências para as praticantes entrevistadas, assume a qualidade de função transcendente e contribui para o desenvolvimento de uma consciência psicológica que gradualmente ordena o caos interior, fortalece a autoestima e orienta para a integração de um complexo de inferioridade milenarmente cultuado, o que favorece a construção de um sujeito comprometido com seu próprio desejo. Palavras-chave: Feminino. Psicologia Analítica. Anima. Animus. Kung fu.<br>Abstract: The objective of the research was to analyze, through the concepts of analytical psychology, the experience of being a woman in kung fu, an ancestral and viripotent combat technique that combines physical and spiritual practices. The sample consisted of nine women practicing kung fu, ranging in age from twenty-one to thirtyeight, recruited by invitation to kung fu academies in Curitiba and Metropolitan Region. As a qualitative research, of a descriptive and hermeneutical nature, the data were collected through semi-structured script interviews and organized according to the empirical phenomenological method of A. Giorgi to obtain categories of analysis, thus identified: (1) ) "Dreaded violence"; (2) "why the kung fu?"; (3) "before kung fu"; (4) "during kung fu"; (5) "relations in the academy"; (6) "as she thinks she is seen"; (7) "to be a woman is to be someone who ..."; And (8) "Kung fu contributions to women." The dichotomy between the sexes has been culturally valued by patriarchal societies and, according to the orthodox jungian view, biologically defined men and women possess the predominant sexual type predominant in their unconscious classically named as the archetypes of anima and animus, respectively. The analysis of the categories obtained revealed that the practice of kung fu, within the current social conjunct called postmodern by contemporary philosophers, favored to these women a range of experiences that have as a product a re-signification of their gender role. This new level of understanding corresponds to the post-jungian proposal that unequivocally dissociates the biological sex from the anima and animus archetypes, now understood to be a property common to men and women, best represented by the notation "anima/us". It is concluded that kung fu, as a physical and psychic locus of experiences for the interviewed practitioners, assumes the quality of a transcendent function and contributes to the development of a psychological consciousness that gradually orders inner chaos, strengthens selfesteem and guides integration of an age-old, inferiority complex, which favors the construction of a subject committed to his own desire. Keywords: Feminine. Analytical Psychology. Anima. Animus. Kung Fu.

Orientadora : Profa. Dra. Victória Z. Cochenski Borba<br>Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências da Saúde, Programa de Pós-Graduação em Medicina Interna. Defesa : Curitiba, 02/09/2016<br>Inclui referências : f. 60-72<br>Resumo: A doença pulmonar obstrutiva crônica (DPOC) é uma doença altamente prevalente, prevenível e tratável. Além do comprometimento pulmonar, diversas condições associadas extrapulmonares são comumente vistas. A redução na densidade mineral óssea (DMO), a presença de fraturas vertebrais e as alterações na composição corporal (CC) que ocorrem nestes pacientes, elevam o risco de exacerbações da doença, pioram a qualidade de vida e aumentam a mortalidade. Este estudo relacionou os dados de DMO, CC, prevalência de fraturas vertebrais morfométricas (FVM), pré-sarcopenia e sarcopenia com os critérios de gravidade e prognóstico de pacientes com DPOC e comparou os resultados com dois grupos controles, além de comparar 4 critérios diagnósticos (Baumgartner, Newman, Misto e FNIH) de pré-sarcopenia e sarcopenia nos três grupos. Todos os pacientes e controles realizaram exame de densitometria óssea, CC e avaliação de FVM no SEMPR (Serviço de Endocrinologia e Metabologia da UFPR). Foram avaliados os dados de 121 pacientes (65 mulheres), média de 67,9 ± 8,6 anos com DPOC (GD), 63 indivíduos tabagistas (GT) (29 mulheres), média de 65,5 ± 8,9 anos e 81 indivíduos não tabagistas (GNT) (47 mulheres), média de 66 ± 8,5 anos. DMO alterada foi observada em 88,4% dos pacientes do GD, com maior número de pacientes com osteoporose neste grupo em relação aos controles (p<0,001). A DMO (g/cm²) nos três sítios avaliados foi menor no GD que nos controles, associado com pior grau de obstrução, estadiamento clínico e índice prognóstico da DPOC (p<0,05). A prevalência de FVM nos pacientes com DPOC foi elevada (57,85%) e maior do que em ambos os grupos controles (GT 23,8% e GNT 14,8%), p<0,001. A CC mostrou menor porcentagem de gordura corporal total no GD em relação aos controles (p=0,04). Pior DMO nos três grupos e nos três sítios avaliados foi associada com menor quantidade de massa magra total (p<0,001). A prevalência de pré-sarcopenia foi maior no GD variando de 19 a 46%, dependendo do critério utilizado, sendo mais prevalente quando utilizado o critério mais atual da literatura (FNIH). No GT a prevalência variou de 20,6 a 39,7% e no GNT de 18,5 a 29,6%. A concordância entre os critérios diagnósticos de pré-sarcopenia foi considerada baixa (kappa <0,40). O diagnóstico de sarcopenia no GD, considerando os 4 critérios, mostrou uma concordância moderada (kappa = 0,57) entre os mesmos e com alta prevalência, variando de 4,9 a 12,4%, também maior pelo FNIH. Existiu uma associação entre sarcopenia e pior prognóstico da doença (OR: 3,50 (1,06 - 11,56), p=0,035), na análise univariada. Concluímos que os pacientes com DPOC apresentaram alterações significativas na massa óssea, na CC e alta prevalência de pré-sarcopenia e sarcopenia quando comparados a controles tabagistas ou não, além de elevado número de FVM. Estas alterações podem levar a pior qualidade de vida, aumento no risco de exacerbações da doença e de mortalidade, também sugerem que a investigação de sarcopenia e de osteoporose deva ser ao diagnóstico da DPOC, para prevenção e tratamento precoces.<br>Abstract: Chronic obstructive pulmonary disease (COPD) is a highly prevalent, preventable and treatable disease. In addition to lung disease, COPD is commonly associated with several extra-pulmonary disorders. The reduction in bone mineral density (BMD), the presence of vertebral fractures and changes in body composition (BC) that occurs in these patients, increase the risk of disease exacerbations, worsen the quality of life and increases mortality. This study linked the BMD data, BC, prevalence of morphometric vertebral fractures (MVF), pre-sarcopenia and sarcopenia with the criteria of severity and prognosis of patients with COPD and compared the results with two control groups. In addition, did a comparison of the 4 criteria (Baumgartner, Newman, Mixed and FNIH) for diagnosis of pre-sarcopenia and sarcopenia in all groups. All patients and controls underwent bone mineral densitometry, body composition exam and evaluation of morphometric vertebral fractures at SEMPR (Serviço de Endocrinologia e Metabologia da UFPR). We evaluated the data of 121 patients (65 women), mean 67.9 ± 8.6 years with COPD (DG), 63 smokers (SG) (29 women), mean 65.5 ± 8.9 years and 81 individuals nonsmokers (NSG) (47 women) mean of 66 ± 8.5 years. Altered BMD was observed in 88.4% of DG patients with a greater number of patients with osteoporosis in this group compared to controls (p <0.001). BMD (g/cm²) in the three sites evaluated was lower in DG than in controls and was associated with worse degree of obstruction, clinical staging and prognostic index of COPD (p <0.05). The prevalence of MVF in COPD patients was high (57.85%) and higher than in both control groups (SG 23.8% and 14.8% NSG), p <0.001. BC showed a lower percentage of total body fat in DG compared to controls (p = 0.04). Worse BMD in the three groups, and in the three sites was associated with lower total lean body mass (p <0.001). The prevalence of pre-sarcopenia was higher in DG ranging from 19 to 46%, depending on the criteria used, being more prevalent when using the most current criteria in the literature (FNIH). In SG the prevalence ranged from 20.6 to 39.7%, and in NSG 18.5 to 29.6%. The agreement between the pre-sarcopenia diagnostic criteria was considered poor (kappa <0.40). The diagnosis of sarcopenia in DG considering the four different criteria showed a moderate agreement between them (kappa = 0.57), with a high prevalence, ranging from 4.9 to 12.4%, also higher by FNIH. Univariate analysis showed an association between sarcopenia and worse prognosis of the disease (OR: 3.50 (1,06 - 11,56), p = 0.035). We conclude that patients with COPD have significant effects on bone mass, BC and high prevalence of pre-sarcopenia and sarcopenia compared to smokers or not smokers. Factors associated with high numbers of MVF, worse quality of life, increased risk of disease exacerbations and mortality, suggesting that initial investigation at the diagnosis of the disease should be done for precocious prevention and treatment.

Defesa: Curitiba, 08/03/2017<br>Inclui referências: f.117-121<br>Resumo: Esta dissertação propõe analisar o livro de memórias do frei capuchinho e capelão italiano Ermenegildo Bortolato. Seu relato de 304 páginas escrito em Veneza no ano de 1947 discorreu sobre o período em que permaneceu prisioneiro na Inglaterra entre 1943 e 1946. Esta análise pretende entender a originalidade da experiência deste sacerdote católico numa época marcada pela ascensão e queda do regime fascista. Nos Campos de Prisioneiros de Guerra, a violência física e psicológica, a constante vigilância dos oficiais britânicos e a dificuldade de exercer os "serviços espirituais", foram aspectos abordados no discurso de Ermenegildo. O capelão também expôs suas impressões políticas sobre a Itália fascista, a guerra na Europa, e a Inglaterra, país que sentia aversão. Seu escrito intitulado: "Tre anni di prigionia sotto gli inglesi, dal maggio 1943 all?agosto de 1946", iniciou com o ano de 1943 e a derrocada do regime mussoliniano na derrota da batalha de El-Alamein, na qual o capelão foi capturado. Entre 1943 e 1946, 400.000 homens do Eixo passaram por campos de prisioneiros na Inglaterra. Os reveses e desilusões de Ermenegildo na prisão foram igualmente os da Itália, país pelo qual lutava e rezava. No cárcere, decidiu pela não colaboração com os ingleses, e por isso foi enviado ao campo de prisioneiros 175, um campo de "reeducação". Conciliar a fé católica, e a "fé" no regime, foi outra faceta de sua vida de prisioneiro. Repatriado em 1946 viu que a Itália assim como ele estava seriamente fragilizada pela guerra. Palavras-chave: Fascismo Italiano, Segunda Guerra Mundial, capelania militar, prisioneiros de guerra.<br>Abstract: This dissertation proposes to analyze the book of memories of the Capuchin Friar and Italian Chaplain Ermenegildo Bortolato. His 304 page report, written in Venice in 1947 chronicled the period when he remained a prisoner in England between 1943 and 1946. This analysis seeks to understand the originality of the experience of this Catholic priest in a time marked by the rise and fall of the fascist regime. In the Prisoners of War camps, the physical and psychological violence, the constant vigilance of British officers, and the difficulty of exercising "spiritual services" was the emphasis of Ermenegildo's speech. The chaplain also exposed his political impressions about fascist Italy, the war in Europe, and England, a country that felt aversion. His letter entitled "Tre anni di prigionia sotto gli inglesi, dal maggio 1943 all'agosto de 1946", began with the year 1943 and the collapse of the Mussolini regime in the defeat of the battle of El-Alamein, in which the chaplain was captured. Between 1943 and 1946, 400,000 men of the Axis passed through prison camps in England. Ermenegildo's setbacks and disappointments in prison were also those of Italy, a country for which he fought and prayed. In the jail, he decided not to collaborate with the English, and so was sent to the prison camp 175, a camp of "re-education". Reconciling the Catholic faith, and "faith" in the regime, was another facet of his life as a prisoner. Repatriated in 1946 saw that Italy just as he was seriously weakened by the war. Key words: Italian Fascism, World War II, military chaplaincy, prisoners of war.<br>Riassunto: Questa tesi si propone di analizzare le memorie del libro del frate cappuccino e cappellano italiano Ermenegildo Bortolato. Il suo rapporto di 304 pagine scritte a Venezia nel 1947, ha parlato del periodo in cui è rimasto prigioniero in Inghilterra tra il 1943 e il 1946. L'analisi mira a comprendere l'originalità l'esperienza di questo prete cattolico in un momento segnato dalla ascesa e la caduta del regime fascista. Nei campi di prigionieri di guerra, violenza fisica e psicologica, la vigilanza costante degli ufficiali britannici e la difficoltà di esercitare "servizi spirituali" è stato la enfasi del discorso di Ermenegildo. Il cappellano inoltre esposto le loro idee politiche sulla Italia fascista, la guerra in Europa, e in Inghilterra, un paese che si sentiva avversione. La sua scrittura dal titolo "Tre anni di prigionia Sotto gli Inglesi, dal maggio 1943 all'agosto 1946", iniziato con l'anno 1943 e la caduta del regime di Mussolini nella sconfitta della battaglia di El Alamein, in cui il cappellano è stato catturato. Tra il 1943 e il 1946, 400.000 uomini di Axis passarono da campi di prigionia in Inghilterra. Il disgrazie e delusioni di Ermenegildo in carcere sono stati anche d'Italia, un paese per il quale lui ha combattuto e ha pregato. In prigione, ha deciso di non cooperazione con gli inglesi, e così è stato inviato al Campo di prigionia 175, un campo di "rieducazione". Conciliare la fede cattolica, e "fede" nello regime, è stato un altro aspetto della sua vita in carcere. Rimpatriato nel 1946 ha visto l'Italia come gli era stato seriamente indebolito dalla guerra.

O conjunto de insumos e materiais utilizados, condições de operação e eficiências obtidas são amplas. O processo há mais tempo estudado e com o maior potencial de aplicação em largas escalas é a destruição catalítica por base, devido principalmente às condições moderadas de reação química e reagentes de baixo custo. Uma das formas do processo é o KPEG, que utiliza polietileno glicol e hidróxido de potássio. Este tratamento de descontaminação foi desenvolvido principalmente em óleo mineral isolante, matriz mais afetada por contaminação com bifenilas policloradas. Pouca informação é encontrada com relação aos resíduos de processo, usualmente na forma de lamas reacionais, limitada a informar que sua destinação deve cumprir legislações territoriais específicas. Nesse trabalho realizaram-se processos de tratamento KPEG na descontaminação de óleos minerais isolantes contendo entre 200 e 330 ppm de bifenilas policloradas para avaliação dos resíduos de reação, separados da lama reacional, e do percentual de descontaminação nos óleos. As análises realizadas nos resíduos revelaram a presença de produtos de reação contendo insaturações, ausentes no polietileno glicol novo, possíveis produtos de complexação com metal alcalino e também a presença de íons cloreto. No óleo foi observada a presença de bifenilas com menor teor de cloros, formadas provavelmente pela descloração parcial de moléculas mais cloradas. A caracterização química do material residual permite a obtenção de informações importantes à investigação de procedimentos para sua recuperação, regeneração e/ou correta disposição. Palavras chave: Bifenilas policloradas, resíduos da reação, KPEG, descontaminação, óleo mineral isolante.<br>Abstract: There are many process capable of removal and/or conversion of polychlorinated biphenyls in several matrix. The set of inputs, materials, operation conditions and efficiencies are widely. The oldest studied process and with largest application potential in great scale is the base catalyzed destruction, mainly due mild chemical reaction conditions and low cost raw materials. One mode of this process is the KPEG, which uses polyethylene glycol and potassium hydroxide. This decontamination treatment was developed mainly on mineral insulating oil, the most affected matrix by polychlorinated biphenyls contamination. Few information is found related to process residues, usually in reaction sludge means, limited to inform that its destination must fulfill specific territorial laws. In these work KPEG treatment process was performed on decontamination of mineral insulating oils containing between 200 and 330 ppm of polychlorinated biphenyls to evaluation of reaction residues, separated from reaction sludge, and of the decontamination percentage. The analysis performed on the residues showed the presence of reaction products containing unsaturation, absents on neat polyethylene glycol, possible organic complexes products with alkali metal as also the presence of chloride ions. In oil was verified the presence of less chlorinated biphenyls, probably formed by partial dechlorination of highly chlorinated biphenyls. Chemical characterization of these residual material allows achievement of important information to explore procedures for recovery, regeneration and/or right disposal. Key words: Polychlorinated biphenyls, reaction residues, KPEG, decontamination, mineral insulating oil.

Esses empreendimentos avançam nos processos de inovação e com produtos de potencial global, competem com outras organizações internacionais, porém as Born globals envolvem-se em uma série de riscos por conta do seu interesse na competitividade internacional. No que se refere o risco, sabe-se que para todos os negócios sempre haverão situações arriscadas e para isso as empresas devem identificar classificar e propor ações de gerenciamento a estes fatores de risco. Com base nessa temática é que se construiu a problemática deste estudo, que tem por objetivo analisar como ocorre o gerenciamento do risco no processo de internacionalização de empresas Born globals de origem brasileira. Para tanto, o setor da indústria de bebidas, mais especificamente de cervejas, foi escolhido em razão de ser altamente competitivo, sendo um dos maiores produtores do mundo, e mesmo nesse cenário, microcervejarias artesanais brasileiras vem se destacando e competindo no mercado nacional e internacional. Adotou-se a pesquisa de abordagem qualitativa, com uso da estratégia de estudo de casos múltiplos, e para isso foram selecionadas 7 microcervejarias com relevância e destaque nacional. Foi utilizada como técnica de coleta de dados a observação não participante, o levantamento documental e as entrevistas semiestruturadas com os fundadores das microcervejarias. A análise dos dados foi realizada pela análise de conteúdo utilizando o software Atlas.ti. Como análise e discussão dos resultados, foi possível caracterizar o processo de internacionalização das empresas, motivadas pelo background e experiência internacional dos seus fundadores, utilizando estratégias para entrada no mercado internacional, como a participação em festivais internacionais, produções colaborativas com cervejarias estrangeiras, resultado do fortalecimento dos networks, e atividades de exportação e importação. Foi possível ainda analisar os fatores de risco que os empreendedores identificam e percebem no processo de internacionalização, classificados entre os riscos comerciais, interculturais, monetários e risco-país, sendo os fatores de risco monetários e do risco-país mais relevantes e que geram maior preocupação por parte das empresas. Identificou-se ainda que esses empreendimentos, utilizam de diferentes ações para mitigação dos riscos, como planejamento e análise do ambiente, pesquisa de mercado, uso de networks, construção de cenários entre outros. Por fim, as contribuições teóricas e empíricas do trabalho referem-se a conjectura de que a evolução das Born globals está relacionada à alta competitividade do mercado, é influenciado pelo background internacional dos fundadores e pela influência do network internacional. O processo de internacionalização é visto com maior comprometimento e também menos riscos são percebidos no processo, além destes se diferenciarem dos riscos presentes em empreendimentos tradicionais, o que influencia a forma como as estratégias e ações de gerenciamento do risco são realizadas nestes negócios. Palavras-chaves: Risco. Gestão do Risco. Internacionalização. Born Global. Cervejaria Artesanal.<br>Abstract: The rapid internationalization process of new and small international ventures, whose international vision has been outstanding since its foundation, brings the phenomenon of Born Globals companies as an important research area in the field of international business. These ventures advance in innovation processes and with products of global potential, compete with other international organizations even with mature and dominant multinationals in the market. In considering this, is noted that these Born globals ventures are involved in a series of risks because of their interest in international competitiveness even though they have no structure and maturity in the business. With regard to risk, is known that for all businesses there will always be risky situations and for this, companies must identify, rank and propose management actions to these risk factors. Based on this theme, the purpose of this study was to analyze how risk management occurs in the internationalization process of Born globals companies of Brazilian origin. To that end, the sector of the beverage industry, more specifically of beers, was chosen because it is highly competitive, being one of the largest producers in the world, and even in this scenario, Brazilian microbreweries have been highlighting and competing in the national and international market. The qualitative research was adopted, using a multiple case study strategy. Seven microbreweries were selected with relevance and national prominence. Non-participant observation, documentary survey and semi-structured interviews with the founders of microbreweries were used as data collection technique. Data analysis was performed by content analysis using Atlas.ti software. As an analysis and discussion of the results, it was possible to characterize the internationalization process of the companies, motivated by the background and international experience of their founders, using strategies for entering the international market, such as participation in international festivals, collaborative productions with foreign breweries, Strengthening of networks, and export and import activities. It was also possible to analyze the risk factors that entrepreneurs identify and perceive in the internationalization process, classified as commercial, intercultural, monetary and country risk, with monetary and country risk factors being more relevant and generating greater risk Concern. It was also identified that these enterprises use different actions to mitigate risks, such as planning and analysis of the environment, market research, use of networks, construction of scenarios and others. Finally, the theoretical and empirical contributions of the work refer to the conjecture that the evolution of the Born globals is related to the high competitiveness of the market, is influenced by the international background of the founders and by the influence of the international network. The process of internationalization is seen with greater commitment and also fewer risks are perceived in the process, besides being differentiated from the risks present in traditional ventures, which influences the way risk management strategies and actions are carried out in these businesses Keywords: Risk.

Como problema de pesquisa, busca-se analisar em que medida a convergência alterou o processo de produção e de formação de equipe de uma rádio all news. Para alcançar tais objetivos, utiliza-se da triangulação metodológica, afim de abarcar os diversos aspectos evidenciados pelo objeto. Neste processo, empregam-se as metodologias de observação sistemática (realizada de maio a setembro de 2016), de entrevistas semiabertas (feitas com nove dos antigos e atuais funcionários da emissora) e de análise de conteúdo, aplicada as entrevistas. A escolha pelo objeto de análise se deu tanto pelo pioneirismo da emissora, que foi a primeira all news do Paraná, inaugurada em 1995 e percursora na disponibilização de áudios na TV por assinatura NET (1995) e na Internet (1996), como pela relevância no estado do Paraná. A base teórica utiliza-se de autores como Jenkins (2006), Ferraretto (2009) e Kischinhevsky (2013). A pesquisa empírica evidencia que o cenário no qual está inserido o jornalista radiofônico é de depreciação profissional, em um sistema que pretende comprometer os processos produtivos na esperança de sanar problemas financeiros ao contratar profissionais que acumulem funções e suprimam etapas produtivas. Palavras-chave: convergência; newsmaking; jornalista; processos produtivas; CBNCuritiba; radiojornalismo.<br>Abstract: This research aims to assess how convergence, as a multidimensional phenomenon transformed both the production and team formation processes in an all news radio. To reach this objective, a methodological triangulation was performed in order to embrace several aspects shown by the object. A systematic observation methodology (performed from may to september of 2016), semi-open interviews (performed with nine former and current broadcaster's employees) and content analysis were used. The analysis object was chosen by the pioneering of the broadcaster, which was the first all news radio in the Paraná state, inaugurated in 1995, and forerunner in making audio available in pay TV (1995) and on the Internet (1996), and also due to the relevance in the Paraná state. The theoretical analysis was based on Jenkins (2006), Ferraretto (2009) and Kischinhevsky (2013). The empirical research shows that the scenario in which radiojournalists are inserted consists of professional depreciation in a system that tries to compromise productive processes in the hope to solve financial problems by hiring professionals to accumulate functions and supress productive steps.

Full textAbstract:
This thesis focuses on the torsional-lateral interactions seen in gear coupled rotors. Of
particular interest are cases where the torsional stiffness parameters affect the lateral
critical speeds and where lateral stiffness and damping parameters affect torsional
critical speeds and amplitudes. A common procedure for critical speed calculations has
been to solve lateral and torsional systems separately. This procedure is tested through
an eigenvalue analysis. It is shown in this thesis, however, that torsional-lateral
interactions play major roles in each other's critical speeds. Some research has
seemingly uncoupled two lateral degrees of freedom from the gear system by choosing
bearing forces and a coordinate system pointing along the line of action and normal to
the line of action. This simplification method has been tested for cases when the lateral
bearing stiffness becomes asymmetric. The force generated by a rotating imbalance also
creates a variable moment arm as the center of mass rotates about the geometric center
of the gear. This variable moment arm is commonly neglected, but is included in the last
case study and its effects are displayed in the results section of this thesis.

Full textAbstract:
Aquest treball investiga la dimensió afectiva de l'aprenentatge de les ciències i es proposa conèixer quines són les actituds i les motivacions envers el seu aprenentatge. El document consta de tres parts diferenciades.<br/>A la primera part de la recerca s'estudien quines són les actituds d'un total de 1064 alumnes de Barcelona (distribuïts per cursos acadèmics des de Sisè de Primària fins a Quart d'ESO) envers diferents aspectes de les classes de ciències, les relacions ciència tecnologia i societat, i les seves prioritats laborals. <br/>Les actituds envers la ciència escolar mostren que l'alumnat està lleugerament d'acord amb el fet que la ciència de l'escola els fomenta l'interès o la curiositat, o els ajuda a tenir més respecte per la natura o a tenir cura de la salut. I alhora, no considera que les ciències siguin molt difícils. És rellevant la manca de vocacions científiques que es constata ja a Sisè de Primària. L'alumnat de la mostra està d'acord amb reconèixer els aspectes positius del paper de la ciència i la tecnologia a la societat, es mostra escèptic envers els aspectes metodològics de la ciència i es mostra en desacord envers les implicacions socials positives del progrés científic. Respecte a les prioritats laborals, es pot concloure que, en general, l'alumnat desitja tenir una feina que li possibiliti desenvolupar-se professionalment, que coincideixi amb els seus valors i que els permeti treballar amb altres persones.<br/>Les actituds envers la ciència escolar obtenen valors més negatius al llarg de l'escolaritat; mentre que envers les relacions ciència, tecnologia i societat i les prioritats laborals es mantenen més constants. Els moments de màxima disminució coincideixen amb la transició Primària - Secundària i amb els cursos on el programa es relaciona bàsicament amb la física i la química. Quant al gènere, només s'observen diferències significatives respecte la tecnologia, situació molt diferent a la dels països anglosaxons on es descriuen diferències en molts altres aspectes.<br/>A la segona part de la recerca s'estudien les possibles diferències actitudinals envers aquests mateixos aspectes segons si l'alumnat expressa la voluntat d'arribar a ser científic o no. Els resultats indiquen que les diferències actitudinals es concentren en els ítems que fan referència a les classes de ciències, i no pas en aquells que fan referència a la importància de la ciència i la tecnologia a la societat o a les prioritats laborals. Així doncs, l'alumnat que expressa que vol continuar estudiant ciències sosté una actitud més favorable envers considerar que les classes de ciències els han mostrat noves professions, que aquestes els milloraran les seves oportunitats laborals i que el que han après els ajuda en la seva vida diària. En canvi, respecte a l'interès i la dificultat o facilitat per aprendre ciències, les diferències actitudinals són menys rellevants. <br/>Finalment, la tercera part de la recerca, de caràcter ex post facto, estudia els motius que 264 persones llicenciades en carreres de l'àmbit científic consideren que varen afectar la seva decisió d'estudiar ciències. Els resultats indiquen que la seva motivació principal per estudiar ciències fou el valor intrínsec i utilitari, mentre que el prestigi laboral, social o econòmic hi tingueren una incidència menor. La influència dels agents socialitzadors, especialment el professorat, fou fonamental en un 40% dels casos, sent el segon motiu més esmentat per haver-se decidit a estudiar ciències.<br>The present study focuses on the affective dimension of science learning, thus the main goal of our research is to examine students' attitudes and motivation towards the learning of science. To present our results, we have structured this document into three parts.<br/>In the first part, we analyze students' attitudes regarding different aspects of sciences classes, the relationship between science, technology and society, and the jobs priorities of a total amount of 1064 Barcelona students (primary and secondary students aged 11- 16). Attitudes toward science classes show that students partially agree that school science promotes their interest or curiosity, helps them develop respect for nature or interest in keeping healthy. Students do not consider school science to be too difficult. It is notable the lack of scientific vocation, that students already showed in the last course of Primary School.<br/>Students agree on the positive aspects of science and technology in the society, but express their skepticism towards the methodological aspects of science and show their disagreement towards the positive social implications of science progress.<br/>Regarding jobs priorities, students tend, in general, to wish for a job that allows their professional development, that is coherent with their values and lets them work with other people.<br/>Attitudes toward school science tend to obtain more negative values throughout the schooling period, while attitudes towards the relationship between science, technology and society and their jobs priorities tend to be constant. The moments of maximum decline coincide with the transition between primary and secondary education and with the science courses in which physics and chemistry is taught.<br/>Regarding gender, there only significant differences are to be found in student's perception of technology. Such situation differs from the findings in Anglo-Saxon countries, where gender differences are notorious in more aspects. <br/>In the second part of the research, we study the possible attitudinal differences between those students who wish to become scientists and those who do not. Attitudinal differences are shown regarding school science but not regarding the relationship between science, technology and society and their jobs priorities. In general terms, those students who wish to become scientists express a more positive attitude towards the role of school science as a means that opens for them doors to new professions, that offers them more job opportunities or that helps them in their daily life. On the other hand, differences regarding their interest or the difficulty of school science are less important.<br/>Finally, in the third part of the research, that is ex post facto in nature, we investigate the reasons that affected students' decisions to enroll in a scientific degree, using a sample of 264 graduates in scientific degrees. Results show that the main motivation to study science lay in its intrinsic and utilitarian value, while issues such as job, social or economical prestige had a minor incidence. The influence of socializers, especially teachers' influence, was fundamental in the 40% of the cases, being the second most common reason given for studying science.

Full textAbstract:
This thesis is concerned with the design of numerical methods for quantum simulation and the development of improved models for quantum relaxation. Analysis is presented for the treatment of quantum systems using the density matrix formalism. This approach has been developed from the early days of quantum mechanics as a tool to describe from a statistical point of view a large number of identical quantum ensembles. Traditional methods are well established and reliable, but they perform poorly for practical simulation as the system size is scaled up. Ad hoc schemes for nuclear spin dynamics appearing in the literature can be shown to fail in certain situations. The challenge is therefore to identify efficient reduction methods for the quantum system which are also based on a rigorous foundation. The method presented in the thesis, for the time–independent Hamiltonian case, combines a quantum density matrix formalism with a procedure based on Chebyshev polynomials; application of the method to Nuclear Magnetic Resonance (NMR) spectroscopy is considered, and it is shown that the new technique outperforms existing alternatives in term of computational costs. The case of a time–dependent Hamiltonian in NMR simulation is studied as well and some splitting methods are presented. To the author’s knowledge this is the first time such methods have been applied within the NMR framework, and the numerical results show a better error–to–cost rate than traditional methods. In a separate strand of research, formulations for open quantum systems are studied and new dynamical systems approaches are considered for this problem. Motivations This thesis work is mainly focused on nuclear spin dynamics. Nuclear spin dynamics constitutes the basis for NMR, which is a very powerful spectroscopy technique that exploits the interaction between nuclear spins and magnetic fields. The same technique is used to reveal the presence of hydrogen atoms in the blood for Magnetic Resonance Imaging (MRI). Within this framework the role of simulations is extremely important, as it provides a benchmark for studies of new materials, and the development of new magnetic fields. The main computational issue is that with current software for NMR simulation it is extremely expensive to deal with systems made of more than few (7–10) spins. There is therefore a strong need to develop new algorithms capable of simulating larger systems. In recent years NMR simulations have been found to be one of the most favorable candidates for quantum computing. There are two reasons for this: nuclear quantum states maintain extremely long coherences, and it is possible to attain a very strong control on the quantum state via the application of sequences of pulses. In order to develop a proper quantum computer it is fundamental to understand how the entangled states lose coherence and relax back to equilibrium by means of external interactions. This process is described as relaxation in an open quantum system. The theory for such systems has been available for 50 years but there are still substantial limitations in the two main approaches. There are also relatively few numerical approaches for the simulation of such systems, for this reason it is important to develop numerical alternatives for the description of open quantum systems. Thesis Outline The thesis is organized as follow: the first two chapters provide background material to familiarize the reader with fundamental concepts of both quantum mechanics and nuclear spin dynamics; in this part of the thesis no new results are presented. The first chapter introduces the concept of quantum systems and the mathematical environment with which we describe those systems. We also present the main equations we need to solve to determine the dynamics of a quantum system in a statistical framework. In the second chapter we introduce the nuclear spin system, that is the physical system that has been the main reference frame in this work, for both tests and practical applications of the new algorithms. We describe how nuclear spin systems are at the basis of very important applications like NMR spectroscopy and MRI. We present in some detail the physical features of the NMR technique and the equations we need to solve to describe the dynamics of a spin system; we also focus on the relevance of numerical simulations for these systems, and consequently which must be the interest in developing new algorithms, and the major obstacles which must be overcome. In the third chapter we investigate the numerical challenges that arise in simulation of quantum systems, we describe some of the methods that have been developed in the literature, focusing on the performances and the computational costs of them, setting the new developments of this thesis in the proper research frame. We discuss one of the major issues: the evaluation of the matrix exponential. We also present the analysis we have done of a recent method called Zero Track Elimination (ZTE) that has been developed specifically for NMR simulations. This analysis shows the limitations of this method but also gives a mathematical explanation of why–and in which cases–it works. In the fourth chapter we present the main result of the thesis, the development of a new method that directly evaluates the expectation values for a quantum simulation via a different application of the well known Chebyshev expansion. We have proved that this new method can provide an excellent boost in terms of performance, with computational costs that can be reduced by a factor ten in common cases. (The results of this chapter and the new method have been presented in international conferences and recently they have been submitted for publication). We also present some attempts we have made in the application of splitting methods for the evolution of the system in a time dependent environment. To our knowledge this is the first time splitting methods have been used for NMR simulations. The results of this approach are as follows: for a particular splitting technique combined with a Lanczos iteration method it is possible to speed up the calculation by a third if compared with a Lanczos type method whilst keeping the error below a critical threshold. This last approach is still a work in progress especially in terms of developing clever ways to split the Hamiltonian. The last chapter of this thesis deals with simulation of quantum systems interacting with an external environment. After presenting the main theoretical approaches for the description of such systems we then survey several the techniques that are currently used for the numerical implementation of such theories. As a work in progress we present a considerably different new approach we have been developing aiming to overcome some of the issues that arise when treating this kind of system within usual frameworks. This is somewhat speculative work that gives rise to some new directions in the development of a numerical description for open quantum systems. We also present some numerical results. (The main core of this chapter has been presented in international conferences).

Full textAbstract:
Amphibians are the most threatened taxon on the planet. Declines have been associated with over-exploitation, habitat loss, pollution, and pathogenic diseases, but of these factors, pollution and disease have been relatively under-studied. Here, I investigated: 1) the impacts of commonly used pesticides on aquatic communities, 2) the effect of these pesticides on amphibian susceptibility to the pathogenic chytrid fungus, Batrachochytrium dendrobatidis (Bd), and 3) whether there are non-amphibian hosts of Bd and 4) how to best quantify the survival of Bd through ontogeny of the host.
In my first research chapter, I quantified the effects of environmentally relevant concentrations of the mot commonly used synthetic fungicide in the US, chlorothalonil, on 34 species-, 2 community- and 11 ecosystem-level responses in a multitrophic-level system. Chlorothalonil increased mortality of amphibians, gastropods, zooplankton, algae, and a macrophyte (reducing taxonomic richness), reduced decomposition and water clarity, and elevated dissolved oxygen and net primary productivity. These ecosystem effects were indirect but were predictable based on changes in taxonomic richness. A path analysis suggests that chlorothalonil-induced reductions in biodiversity and top-down and bottom-up effects facilitated algal blooms that shifted ecosystem functions.
In my second chapter, I investigated how a wide range of ecologically relevant concentrations of chlorothalonil affected four species of amphibians (Osteopilus septentrionalis, Rana sphenocephala, Hyla squirella and H. cinerea). I also evaluated the effects of chlorothalonil on liver tissue, immune cell density, and the stress hormone, corticosterone. Chlorothalonil killed nearly every amphibian at the expected environmental concentration (EEC) and, at concentrations to which humans are commonly exposed (up to the EEC), it was associated with elevated corticosterone levels and changes in immune cells. Three species (O. septentrionalis, R. sphenocephala, and H. cinerea) showed a non-monotonic dose-response, with low and high concentrations causing significantly greater mortality than intermediate concentrations and controls. Corticosterone exhibited a similar non-monotonic dose response and chlorothalonil concentration was inversely associated with liver tissue and immune cell densities. These studies on chlorothalonil emphasize the need to re-evaluate its safety and to further link anthropogenic-induced changes in biodiversity to altered ecosystem functions.
In my third research chapter, I investigated the effects of chlorothalonil and atrazine, one of the most commonly used herbicides in the US, on amphibian susceptibility to Bd, a leading cause of amphibian extinctions. Relative to controls, atrazine monotonically reduced Bd growth in culture and on tadpoles. In contrast, chlorothalonil non-monotonically reduced Bd growth in culture and on tadpoles, with low and high concentrations causing significantly greater mortality than intermediate concentrations and controls. This study is one of only a handful of studies to document a non-monotonic dose response of an invertebrate (Bd) to a pesticide. Although both pesticides reduced Bd growth on tadpoles and in culture, neither eliminated Bd entirely, and because we know little about the long-term effects of the pesticides on hosts (e.g., immunosuppression), I do not recommend using these chemicals to control Bd.
In my fourth research chapter, I investigated whether there are non-amphibian hosts for Bd. Non-amphibian hosts could explain how Bd is able to persist in the environment after amphibians are extirpated, and the extreme virulence and distribution of Bd. In laboratory and field studies, I found that crayfish, but not mosquitofish, were hosts for Bd. I found that crayfish could be infected with Bd, could maintain that infection long term (at least 3 months) and could transfer that infection to susceptible amphibians. I also revealed that exposure to water that previously held Bd caused significant crayfish mortality and gill recession, suggesting that Bd releases a chemical that can cause host pathology in the absence of infection. Most efforts to conserve and restore amphibian populations challenged by Bd have been unsuccessful, but managing alternative hosts offers a new and potentially more effective approach to managing Bd. Likewise, identifying the specific pathology-inducing chemical released by Bd might facilitate the development of new strategies to reduce the risk posed by this pathogen.
The fifth and sixth research chapters are aimed to improve the quality and efficiency of Bd research. During amphibian development, Bd infections transition from the mouthparts of tadpoles to the skin of post-metamorphic frogs but this transition has never been quantified and thus researchers might be sampling the wrong parts of amphibian bodies to detect Bd. I showed that Bd abundance in O. septentrionalis mouthparts declined from Gosner stages 35-42 and increased on epidermis from Gosner stages 38-46. Assuming our findings are general across species, I recommend sampling mouthparts of amphibians less than Gosner stage 41 and hind limbs of amphibians greater than Gosner stage 41. This should provide researchers with guidance on where to sample to maximize detection of Bd.
I also investigated whether Trypan blue dye could be used to determine the viability of Bd. I showed that the proportion of zoospores stained with Trypan blue dye matched the proportion of known dead zoospores added to cultures. In contrast, all of the zoosporangia stage (including known dead zoosporangia) of Bd stained blue. These results demonstrate that Trypan blue can be used to determine the viability of Bd zoospores but not zoosporangia. I recommend using Trypan blue to report the number of live zoospores to which hosts are exposed and to help determine whether factors have lethal or sublethal effects on Bd.
My work demonstrates that managing exposure to contaminants and biological reservoirs for Bd might provide new hope for imperiled amphibians. Further exploring how pesticides and pathogens are contributing to amphibian declines will allow us to formulate crucial management and conservation plans to begin remediation.

Full textAbstract:
In 2008, 75% of municipal sport and recreation facilities in South Africa were underutilised,
while 62% of these facilities were reported to be poorly managed (SRIMP,
2008). A possible reason for these reported findings can be the lack of managerial
skills. However, Goslin (2003:39) mentions that little research on recreation
management and education has been done in South Africa, which highlights the
increasing need for knowledge to establish and maintain future management practices
(Goslin, 2003:40). Therefore, the purpose of this study was to examine the
management competencies applied by recreation managers for effective management
of local community centres. In addition, this study compares the gaps between the
recreation managers’ qualifications and the requirements for successfully providing the
public with quality recreation opportunities in community centres.
A qualitative method was applied as a practical guide for the research. The seven
regional recreation managers of the City of Johannesburg were selected for the case
study. The sample size (n=5) was determined through data saturation. Data was
gathered by means of a semi–structured interview with each regional manager (De Vos,
2005:296; Veal, 2006:386). Through the process of data analysis two main categories
were identified. The first, Tasks and limitations experienced by regional managers
in Johannesburg pointed out that the daily tasks of facility, programme and human
resource management is seen as essential responsibilities to recreation managers and
it is unfortunate that the majority of problems relating to these tasks are due to unskilled
staff that must be supervised on a daily basis. The second, Training needs of
recreation staff at recreation centres: Regional managers’ perspective indicated
that the staff’s inability to understand the term recreation may in fact be caused by
organisations’ bad choices regarding employment or the lack of setting clear criteria for
job positions (Mull et al., 2005:227). The answer to training needs for already employed
personnel, saving both money and time, may be short courses. By working with each specific centre’s problems and training needs, as well as with each individual
employee’s competencies, the short courses could be designed to specifically help
better equip the staff member and in turn provide better recreation services to the
community.<br>Thesis (M.A. (Recreation Science))--North-West University, Potchefstroom Campus, 2011.

Previous issue date: 2005<br>Objective: study the possible change on mode of deaths, medical decision practices and family participation on decisions for limiting life-sustaining treatments (L-LST) over a period of 13 years in three pediatric intensive care units (PICUs) located in southern Brazil. Methods: a cross-sectional study based on a retrospective chart review (1988 and 1998) and on prospective data collection (from May 1999 to May 2000). Setting: three Pediatric Intensive Care Units (PICUs) in Porto Alegre, Southern Brazilian Region. Patients: children who died in those PICUs during the years of 1988, 1998 and between May 1999 and May 2000. Results: the 3 PICUs admitted 6233 children during the study period with a mortality rate of 9. 2% (575 deaths) and 509 (88. 5%) medical charts were evaluated in this study. Full measures for life support (F-CPR) were recognized in 374 (73. 5%) children before dying, brain death (BD) was diagnosed in 43 (8. 4%) and 92 (18. 1%) underwent some limitation of life support treatment (LLST) There were 140 (27. 5%) deaths within the first 24 hours of admission and 128 of them (91. 4%) received F-CPR, while just 11 (7. 9%) patients underwent L-LST. The average length of stay (LOS) for the death group submitted to FCPR was lower (3 days) than the L-LST group (8. 5 days, p<0. 05). The rate of FCPR before death decreased significantly between1988 (89. 1%) and 1999/2000 (60. 8%) while the L-LST rose in this period from 6. 2% to 31. 3%. These changes were not uniform among the 3 PICUs, with different rates of L-LST (p<0. 05). The families were involved in the decision-making process for L-LST in 35. 9% of the cases, increasing from 12. 5% in 1988 to 48. 6% in 1999/2000. The L-LST plans were recorded in the medical charts in 76. 1% of the deaths, increasing from 50. 0% in 1988 to 95. 9% in 1999/2000. Conclusion: we observed that the modes of deaths in southern Brazilian PICUs changed over the last 13 years, with an increment in L-LST. However, this change was not uniform among the studied PICUs and did not reach the levels described in countries of the northern hemisphere. The family participation in the L-LST decision-making process has increased over the time but it is still far behind from what is observed in other parts of the world.<br>Objetivo: Estudar uma possível mudança nos modos de óbitos, nas atitudes dos processos de decisão da equipe médica e na participação da família nas decisões de limitação de tratamentos (LT), ao longo dos últimos treze anos em três Unidade de Terapia Intensiva Pediátricas. (UTIP) Métodos: Coorte histórico transversal, de três momentos (revisão de prontuários nos anos de 1988 e 1998) e contenporaneo (todas as informações disponíveis ao residente de terapia intensiva pediátrica de maio de 1999 e maio de 2000), descritivo, transversal e não intervencionista. Local: Três UTIP de Porto Alegre, sul do Brasil. Pacientes: Todos os pacientes que faleceram nos anos de 1988, 1998 e de maio de 1999 a maio de 2000. Resultados: Foram admitidos 6. 233 pacientes, com uma taxa de mortalidade de 9,2% (575 óbitos). Destes pacientes, 509 (88,5%) atenderam aos critérios de inclusão. Receberam todas as medidas de suporte vital (RCP) 374 (73,5%), tiveram diagnóstico de morte encefálica (MEN) 43 (8,4%) e limitação de algum tratamento de suporte vital (LT) 92 (18,1%). Dos óbitos, 140 (27,5%) ocorreram nas primeiras 24 horas de internação e destes, 128 (91,4%) no grupo de RCP e apenas 11 (7,9%) no de LT. A mediana dos tempos de permanências nos óbitos com RCP foi menor (3 dias) do que nas LT (8,5 dias) com p<0,05. As RCP caíram de modo significativo entre 1988 (89,1%) e 1999/2000 (60,8%), enquanto as LT aumentaram neste período de 6,2% para 31,3%.A evolução destas mudanças não foi uniforme entre as UTIP, tendo uma delas apresentado taxas significativamente maiores nas LT. A maioria das decisões de LT foi tomada pela equipe médica (60,3%) e as famílias participaram destas decisões em 35,9% dos casos, com aumento de 12,5% em 1988 para 48,6% em 1999/2000. Os planos de LT foram registrados nos prontuários em 76,1% dos óbitos, com aumento de 50,0% em 1988 para 95,9% em 1999/2000. Conclusão: Houve uma mudança nos modos de óbitos, ao longo dos anos, com aumento das decisões de LT e diminuição dos óbitos apesar de RCP, embora não de modo uniforme entre as UTIP estudadas e também não atingindo, neste particular, os níveis dos países do hemisfério norte. As famílias estão participando mais das decisões de LT e estas são, na maioria dos casos, tomadas pelas equipes médicas. As UTIP do sul do Brasil atendem, com muita freqüência, emergências médicas, com grande número de óbitos nas primeiras horas de internação e por doenças infecciosas.

Full textAbstract:
This study aimed to investigate the feeding behaviour of the calanoid copepod, Pseudodiaptomus hessei, particularly whether it prefers to feed on a planktonic or benthic food source. The effect of different microalgae species on the feeding preference, ingestion, and gut evacuation rate were investigated. Two microalgae species (Isochrysis galbana and Tetraselmis suecica) were used, to test gut fullness and gut evacuation of P. hessei. The copepods were starved for 6 h and allowed to feed on monalgae diets, I .galbana and T. suecica, and a 1:1 binary diet mixture of T. suecica and I. galbana. The gut fullness and gut evacuation rates were determined by observing under the dissecting microscope and gut content percentage was recorded (as 0, 25, 50, 75 or 100 percent) along with copepod sex. Copepods that feed on T. suecica fill their gut after 30 min, while those that feed on I. galbana do so after 40 min. There was a significant difference (p= 0.02) between sexes with males filling their gut faster than females. However, copepods that fed on I. galbana evacuated their gut content completely after 30 min, while those fed on T suecica evacuated theirs after 40 min. There was no difference between males and females for gut evacuation. Even though there was high gut fullness rate when P. hessei was feeding on T. suecica, I. galbana is recommended as the best mono-algae diet to culture P. hessei. The feeding behaviour of P. hessei was investigated, as to whether it prefers to feed on a planktonic or benthic food source. Copepods were starved for 3 h and then allowed to feed on two microalgae species (I. galbana and T. suecica), one presented as a benthic and other as planktonic. Controls included swapping the modes of presentation for each algae species. Ingested microalgae species were quantified using real-time PCR, with threshold cycles interpreted as relative abundance ratio (planktonic microalgae divided by benthic microalgae species). Pseudodiaptomus hessei preferred to feed on planktonic food sources initially as there was a difference between planktonic and benthic ingested food (p=0.026). Copepods shifted from planktonic to benthic food sources after 80 min of feeding planktonically. Planktonic food sources were the preferred choice for P. hessei regardless of microalgae species offered. The results from this study also confirm that P. hessei feed on a benthic food source during the day under culture conditions. This information can be used as baseline information for aquaculturists to rear the species as live feed for marine fish larvae.

The work presented here further validates this hybrid method by optimizing the crystal structures (experimental and submitted) of the first three CCDC blind tests held in 1999, 2001, and 2004. Except for the crystal structures of compound IX, all structures were reminimized and ranked according to their lattice energies. The hybrid method computes the lattice energy of a crystal structure as the sum of the DFT total energy and a van der Waals (dispersion) energy correction. Considering all four blind tests, the crystal structure with the lowest lattice energy corresponds to the experimentally observed structure for 12 out of 14 molecules. Moreover, good geometrical agreement is observed between the structures determined by the hybrid method and those measured experimentally. In comparison with the correct submissions made by the blind test participants, all hybrid optimized crystal structures (apart from compound II) have the smallest calculated root mean squared deviations from the experimentally observed structures. It is predicted that a new polymorph of compound V exists under pressure.

Quinn, Phillip James. "Managerial ownership and incentive alignment : evidence from mandatory stock ownership plans." Diss., University of Iowa, 2014. https://ir.uiowa.edu/etd/4727.
Full textAbstract:
Mandatory stock ownership plans require executives to hold a minimum level of stock. I exploit these changes in managerial stock ownership to examine the relation between managerial ownership and manager-shareholder incentive alignment. In contrast to prior work that suggests equity incentives induce opportunistic managerial behavior, I find earnings management declines following the adoption of mandatory stock ownership plans relative to a propensity-matched control sample. I also posit and find a reduction in bid-ask spreads following plan adoptions, consistent with manager-shareholder incentive alignment improving market liquidity and decreasing information asymmetry. These findings are consistent with boards of directors contracting with managers to reduce the agency costs of equity.

Peralta, Denis. "Three Essays on Big-Box Retailers and Regional Economics." DigitalCommons@USU, 2016. https://digitalcommons.usu.edu/etd/4727.
Full textAbstract:
The big-box retail stores such as Wal-Mart and Target have become the focus of many studies researching their impacts on local economic outcomes. This dissertation studies three related topics: (i) the dynamic interrelationship among the presence of the big-box stores, retail wage, and employment, (ii) the impact of the big-box retailers on personal income growth, and (iii) the dynamic interrelationship between the presence of big-box retailers and personal income growth. The research draws important insights with potential implications for regional developers and policy makers.
The first essay analyzes the dynamic relationship among the presence of the big-box retailers, retail wage, and employment at the county level for 1986-2005. A vector autoregression model is applied on panel data. Impulse response functions and variance decompositions are also presented. Results suggest that the presence of big-box stores decreases retail wages and increases retail employment. Retail employment has a higher impact on the retailers’ location decision than retail wage. The results also show that the presence of Wal-Mart drives the above-mentioned effects, while the presence of Target is insignificant.
The second essay investigates the impact from the presence of big-box retailers on personal income growth in U.S. counties between 2000 and 2005 - based on neoclassical growth models of cross-country income convergence. Results suggest that counties having both Wal-Mart and Target stores experienced slower growth in personal income. After controlling for spatial autocorrelation, similar to the first essay, the effect of Wal-Mart’s presence on personal income growth is dominant in terms of statistical significance relative to Target’s.
The third essay expands the second essay and investigates the dynamic interaction between the presence of big-box retailers and personal income growth over time at the county level for the period 1987-2005, using a panel vector autoregression model. For this analysis, the earning shares of natural resources and manufacturing sectors are included - assuming that all the variables are endogenous to one another. The findings indicate that big-box retailers negatively affect personal income growth, which is consistent with the second essay. However, personal income growth has an insignificant effect on the big-box retailers’ location decision.

Full textAbstract:
Building upon self-determination theory, this study sought to ascertain the reach of teacher autonomy support beyond its well-documented impact on student autonomy and engagement to include student competence and relatedness, as well as to parse apart specific teacher behaviors that comprise autonomy support (i.e., respect, choice, relevance, coercion) and their unique influences on the multiple motivational outcomes, surrounding the transition to middle school. These questions were examined using information from 224 fifth graders, 339 sixth graders, and 345 seventh graders attending elementary and middle schools in a predominantly Caucasian working and middle class school district.
Regression analyses, predicting change in student motivation over time, revealed that students' experiences of their teachers' autonomy support in the fall predicted changes in student competence, relatedness, and engagement from fall to spring. Although teacher autonomy support was positively connected to student autonomy in correlational analyses, it did not predict changes in student autonomy from fall to spring. Unique effect analyses regressing each of these motivational outcomes on all four components of teacher autonomy-support revealed that respect, relevance, and coercion were unique predictors of each outcome concurrently, but that choice only made a unique contribution to autonomy and relatedness.
Developmental patterns extracted from multiple regression analyses in all three grade samples indicate that respect is most predictive of fifth grade student motivation, respect and coercion are most salient for sixth grade motivation, and respect, coercion and relevance together are most central to seventh grade students. MANOVA analyses of mean levels showed the expected patterns of differences, namely: compared to fifth graders, sixth graders reported lower levels of teacher autonomy support (and every component) and seventh graders showed even lower levels still. Further, students reported lower levels of all four motivational outcomes with the same pattern as autonomy support differences. MANCOVA analyses examined whether grade differences in teacher autonomy support could account for this pattern of grade differences in motivational outcomes. When analyses controlled for levels of teacher autonomy support, mean levels of relatedness were no longer significantly different across grades. Although still significant, MANCOVA analyses for autonomy, competence, and engagement showed much smaller F-values when teacher autonomy-support was entered into the model.
Together, these findings illustrate that teacher autonomy support does predict student competence and relatedness, in addition to autonomy and engagement. Additionally, it highlights the importance of several components of teacher autonomy support, especially for middle school students. Finally, it points to the need for further investigation on how teacher autonomy support, as an organizational construct and as separated by its components, impacts key motivational outcomes for students in different grades surrounding the middle school transition. Implications for researchers and educational practitioners are discussed.

Haney, Douglas C. "What Matters Most To Mayors Making Interlocal Agreement Decisions." ScholarWorks, 2018. https://scholarworks.waldenu.edu/dissertations/4727.
Full textAbstract:
Local governmental units in the United States are struggling to cope with dwindling public resources and surging public demands. They often turn to interlocal agreements (ILAs) as a collaborative means by which to more effectively serve their constituents. Unfortunately, many ILAs never materialize or fail prematurely. The purpose of this qualitative, phenomenological study was to explore the experiences of 13 purposefully selected mayors in the State of Indiana to discover what factors they considered important when making their ILA entry and continuation decisions. It utilized a conceptual framework based on the transaction costs theory, as informed by the utility maximization, bounded rationality, social decision scheme, and groupthink theories. Interviews were transcribed, and data were subjected to an inductive analysis using idiographic interpretation to develop themes and to describe the essence of the ILA decision-making process. Key findings included that direct cost savings, a detailed, written agreement, contractual flexibility, an ability to perform, the effect on constituents and the current municipal workforce, and having a trusted, like-minded partner were important ILA entry factors. Furthermore, contractual flexibility, meeting constituent expectations, service effectiveness, relevancy, having a communicative partner, being able to measure an ILA service, and saving money were important ILA continuation factors, but that both service quality and doing the right thing trumped saving money. These findings have implications for positive social change because they can assist local leaders in achieving ILA success, with society benefitting from a commensurate increase in public value and in the more efficient and effective meeting of societal needs.

Full textAbstract:
Within the context of communicative language Teaching, teachers have a tendency to stress communicative fluency rather than linguistic accuracy in error treatment. This study uses Aramco ESL teachers, students, and classes where teachers from different-educational backgrounds teach English to adult Saudi employees within its English language program, as an example to explore this tendency. The study hypothesis that native-speakers, given their different educational background tend to stress communicative fluency while the non-native speakers tend to stress linguistic accuracy. Hence, the study attempts to present an account of how these teachers look at errors and how they treat them in class, to reach some findings about this hypothesis. The study applies multiple methods in data collection including a teacher's questionnaire designed by the researcher, followed by classroom observations along with audio-recordings of those classes. The classroom observation scheme used is adapted from Spada and Frohlich's COLT observation Scheme-Part A- (Communicative Orientation of Language Teaching). The students' preferences to error treatment were also explored by using a students' questionnaire designed by the researcher, to add dimensions to the findings. To analyse elements in the research context, Likert Scale for coding responses to the questionnaires was used to provide numbers and percentages for analysis. Then, samples of classroom discourse collected from the audio-recorded observations were transcribed to analyse teachers behavior toward errors in class. To add further dimensions to the findings, the findings were discussed in view of Chaudron's illustration in his model: Features and Types of Corrective Reaction in the Model of Discourse. The findings were also discussed in view of Chaudron's Table: Rate of Error Production and Teacher Treatment, for the same reason. By using Chaudron's model and table in the discussion, the study aims to provide a sound interpretation of the strategies that Aramco teachers use to treat errors and whether these strategies reflect principles of Communicative Language Teaching. The study identifies several distinctive issues from the research context including opinions and beliefs of Aramco teachers and students about errors treatment. It also identifies types of strategies these teachers use in treating their students' errors in class, and provides conclusions that demonstrate that both NSs and NNSs have beliefs and strategies that promote both communicative fluency and linguistic accuracy although NNSs showed noticeable tendency for linguistic accuracy more than their native-speaking counterparts did.

Full textAbstract:
Masters in Public Administration - MPA<br>This study has been conducted before when the company in question underwent a
restructuring (name change) but did not threaten the loss of jobs. This study is being conducted again because another restructuring has taken place over the period of 2011/2012 and involved the retrenchment of employees nationally. The company represented in the study is one of the largest cleaning companies in South Africa and has a very broad and influential client base. They are in high demand in the cleaning industry and have positively impacted many companies and organisations over their many years of existence. Because of the magnitude of the workplace restructuring this time around, more people have been affected (both those who were retrenched as well as those who were left behind). According to Vermeulen, 2002, “Downsizing” is a term that emerged in managerial circles and was used in the business press, but no precise theoretical formulation underpins any clear definition of the term. When hearing the term downsizing, one often will use this together with the term “laying-off” interchangeably. However, some
authors will focus on different elements of downsizing for example in reporting on a
comprehensive study of downsizing in American industry, Cameron, Freeman and
Mishra (1993) limited the term's use to a programme which is an intentional process. This process involves an overall reduction in personnel with a view to improving the efficiency of the organisation. The process wittingly or unwittingly affects work processes at the organisation concerned. According to Hellgren, et al (2005), the attitudinal constructs investigated in this study were job satisfaction, job involvement, organisational commitment, and turnover intention. Job satisfaction represents a general affective response to the overall job situation. Following Locke (1976, p. 1300), we define job satisfaction as “a pleasurable or positive emotional state resulting from the appraisal of one’s job or job experience”. ...employees who survived downsizing were likely to experience high levels of stress and decreased levels of organizational commitment and motivation. These individuals are often known as the "victims" of downsizing due to research that documents the devastation of job loss, focusing on negative consequences in terms of psychological and physical well-being (Bennett, Martin, Bies, & Brockner, 1995; Cappeili, 1992; Fallick, 1996; Leana & Feldman, 1992). This study inevitably aimed to prove that workplace restructuring very well has an effect or impact on an employee’s job satisfaction, whether these effects were positive or negative. The findings of the study highlighted significant positive correlations between the two variables and highlights strong relationships between employees’ career advancement opportunities and job satisfaction; trust and job satisfaction, communication and job satisfaction, as well as employee commitment and loyalty and job satisfaction whereas trust (2) or employee morale seem to have no significant relationship with job satisfaction.

Full textAbstract:
La explosión demográfica, la crisis del agro en la sierra, la búsqueda de mejores oportunidades de trabajo, estudio; entre otros factores, fueron las causas que impulsaron las primeras grandes oleadas de migrantes provincianos a las principales ciudades del Perú, y en mayor medida Lima, entonces, la ciudad capital se convirtió en el gran imán que atrajo a poblaciones de los distintos departamentos (hoy regiones). La instalación de los migrantes no fue sencilla, pues tuvieron que lidiar con la marginación social, el racismo, la falta de oportunidades laborales y la carencia de una vivienda adecuada. Esta última fue una de las principales causas de las grandes invasiones a tierras públicas y privadas que fueron vistas como “el modo normal” que hizo posible el acceso a un lote para vivienda. Hecho que no cambió con el pasar de los años, ya que todavía se siguen produciendo al margen de las leyes. Las invasiones dieron origen a las barriadas, que “inicialmente fue enfocado como un problema para la sociedad y considerado un cáncer social a erradicarse” (Calderón 1990:30). Desde sus orígenes, y en años posteriores, se les ha considerado un lupanar, un espacio donde la vida se prostituye; una ofensa para las personas que vivían en la “ciudad legal” como se muestra en la siguiente cita: “La barriada lo ofende todo. Ofende la vista, ofende el olfato y ofende el corazón. Es un inmundo lupanar en donde la vida humana se prostituye cada día y es, en verdad, la viga en el ojo de todos los limeños”. Sin embargo, para los migrantes estas valoraciones no fueron importantes, porque al margen de estas consideraciones las invasiones y la formación de nuevas barriadas continuaron. Para ellos esto fue solo una reivindicación de los derechos —el acceso a un lote y por ende a la tierra— que poseían como personas nacidas en el Perú,3 y en la década de los 60s el mismo Estado las asumió como una política para resolver la crisis de vivienda que enfrentaba nuestro país. Junto a los invasores, que necesitaban un lote para vivir, también estuvieron los usurpadores de tierras, que so pretexto de requerir una vivienda, invadían y luego realizaban los llamados “traspasos”. El crecimiento y la transformación de la ciudad en una megápolis están estrechamente vinculados a las invasiones. La Lima del siglo XX se entiende dentro de este contexto, pues originaron los llamados conos Norte, Sur y Este. La conquista de la arena y su conversión en un barrio y eventualmente en un distrito no fue fácil, porque tuvieron que exigir al Estado su reconocimiento y demandar los servicios de agua, desagüe y luz. A esto se suma el flagelo de Sendero Luminoso que en las décadas de los 80’s y 90’s casi hizo desaparecer las organizaciones barriales, ya que los dirigentes fueron amedrentados, amenazados, y en algunos casos asesinados, como sucedió con María Elena Moyano, una de las dirigentes más importantes de Villa El Salvador. Extrañamente el fenómeno de las invasiones fue dejado de lado por nuestra disciplina, y más bien fue abordado por otras de las Ciencias Sociales; por eso, nuestro interés en esta investigación es analizar dos de ellas desde un enfoque histórico y sobre este eje hemos desarrollado los capítulos, nuestros objetivos y demostrado nuestra hipótesis. La investigación se inició con la revisión de los textos que trabajaron las invasiones a lo largo del siglo XX - materia de nuestro estudio -. No obstante, para reconstruir la historia de ambas invasiones hemos considerado necesario acudir a las fuentes de la época, ello con el objetivo de tener una imagen más completa sobre el hecho.<br>Tesis

Full textAbstract:
Cette etude s'interesse aux phenomenes caracteristiques de la formation et de l'interaction des sillages turbulents en aval d'obstacles cylindriques en configuration complexe. Pour le bas regime sous-critique de nombre de reynolds nous effectuons une investigation de la zone de proche sillage de facon a la fois experimentale via des mesures de vitesse par anemometrie laser doppler et numerique via des simulations 2d avec raffinement du maillage en paroi. Dans un premier temps nous etudions le cas de l'interaction forte entre deux cylindres en parallele dont l'ecartement bord a bord est inferieur au diametre. L'effet de blocage se traduit par l'apparition d'un jet inter-tubes. Deux regimes sont identifies par rapport a une valeur critique re#c du nombre de reynolds. En deca de re#c le jet se plaque de facon stable du cote de l'un des cylindres provoquant une disymetrie du double sillage forme en aval. Des nombres de strouhal differents sont retrouves dans la zone arriere de chacun des tubes. Au-dela de re#c le jet adopte un mouvement de battement aleatoire de part et d'autres de l'axe median des tubes. Nous relions l'apparition de ce phenomene d'intermittence a grande echelle de l'ecoulement a la naissance d'instabilites 2d de kelvin-helmholtz au sein de la couche cisaillee decollee. Ces deux effets d'asymetrie et de battement de l'ecoulement (selon le regime) s'estompent au-dela de cinq diametres pour laisser place a un sillage unique qui tend vers une etat de turbulence quasiment developpee. Les phenomenes de melange a grande echelle et de transfert d'energie et dissipation a petite echelle sont favorises par cette configuration d'interaction forte. Enfin, nous etudions experimentalement le cas plus complexe de l'ecoulement au sein et en aval d'un faisceau de tubes en quinconce a des regimes de reynolds equivalents. Les proprietes de melange sont accentuees par rapport au cas geometriquement et hydrodynamiquement equivalent de l'interaction forte entre deux tubes.

Full textAbstract:
Fogwater Harvesting has been demonstrated to be able to provide water for small rural communities in arid and semi-arid regions. Fog droplets coalesce on mesh screens and flow by gravity into a supply network. The technology is simple and can be maintained and managed by the users. The challenge is identifying suitable communities, environmental conditions and ensuring the system meets user demand sustainably. Following the First International Conference on Fog and Fog Collection (19-24 July 1998), a general project cycle for fogwater harvesting for domestic water supply is proposed and discussed. Methodologies and examples are reviewed and placed in an interdisciplinary project framework.
