The FONT beam-based, intra-train feedback system has been designed to provide beam position stabilisation in single-pass accelerators. A FONT feedback system utilising position information from three high-resolution cavity beam position monitors (BPMs) has been commissioned at the interaction point (IP) of the Accelerator Test Facility 2 (ATF2) at KEK, Japan. The ultimate goal of the feedback in the IP region is to stabilise the low-emittance electron beam to the nanometre level. The operation, optimisation and resolution performance of this IP system forms the subject of this thesis. The IP feedback system makes use of beam position measurements from the BPMs to drive an upstream kicker and provide a local correction. The BPMs have a fast decay time of ~25 ns to allow bunches within the beam train to be resolved. The operation of the IP BPMs, the noise floor, and position sensitivity to phase are discussed in detail. Attempts are made to diagnose an unwanted ~60 MHz oscillation in the cavity signals, which is bunch charge-dependent and thus likely beam generated. The BPM resolution estimate was notably improved from 50 nm to 20 nm using waveform integration in analysis of the BPM signals. A multi-parameter fit was used to address inaccurate calibrations and charge-dependencies to achieve more consistent resolution performance and produce a best-ever resolution estimate for the BPMs of 17.5 ± 0.4 nm. A novel mode of IP beam position stabilisation using two BPMs as input to the feedback has been successfully demonstrated. The beam position was stabilised to 57 ± 4 nm, as measured at an independent BPM. Feedback performance was improved to this level by sampling the waveform to optimise bunch-to-bunch correlation. Analysis suggests correction capability could be enhanced by firmware waveform integration to achieve a measurable beam stabilisation of ~40 nm in the future.

This thesis explores human resource management (HRM) adoption by investigating the influence of multiple HRM actors’ social position, capital resource(s) exchange mechanism, dispositions, social classes, habitus, social expectation, and national and global environmental factors. The objectives of this thesis were achieved through systematically conducting three different studies for the thesis. The first study was carried out to gain insight into the influence of social position on HRM academics’ adoption. The major contribution of this study was a theorising model on HRM academics’ adoption. It shows which capital resource is very sought after and how it plays a role in developing HRM academics’ dispositions, which in turn provides them with the drive and motivation to adopt western HRM ideas and knowledge. The second study was carried out to gain insight into the mechanism and formation of capital resource(s) exchange that influences HRM practitioners to adopt western HRM ideas, knowledge, and practices. The main contribution of this study comprised empirical insights into the importance and role of social class (élite and emerging class); habitus and socialisation (primary and secondary socialisation) as developers and controllers of the mechanism of capital resource(s) exchange; and formation of social position. The third study investigated a gap between accepted (adopted) HRM ideas and knowledge, and actual HRM practices. The major contribution of this study was its theorising on the factors that influence this gap. It explored the influences of conflicting factors such as actors’ professional and occupational orientation and position, social position, and social expectation, which develop the gap. This thesis adopted a qualitative abductive research approach. It conducted qualitative indepth interviews with 19 HRM academics, 15 MBA-Alumni HRM practitioners, and 10 non-MBA-Alumni HRM practitioners. Qualitative observation in two business schools and five business organisations in multiple industries was carried out to enrich the data collection. This thesis contributes to the existing body of knowledge by providing insights into individual actors’ level HRM adoption, which is an underexplored area in Pakistan and similar developing countries. By employing theoretical and analytical tools based on Bourdieu’s theory of practices and social position, Rogers’s and Tarde’s theorising of adoption, and findings of empirical studies of macro institutions, cultural sensitive views, and institutional factors’ framework in the diffusion of HRM, this thesis explored, examined, and theorised HRM adoption at different individual actors’ level in business organisations and business schools in Pakistan. In that respect, this thesis theoretically contributes to Bourdieu’s theory and its unique use in international HRM, organisation studies, and management research. This thesis empirically contributes to the understanding of management and think tanks in business schools, business organisations, educators, HRM practitioners, and relevant government and regulatory bodies who can benefit from the findings of this research by understanding the different factors and social structures affecting western HRM’s effectiveness and its applications. It also suggests to these stakeholders the factors that affect individuals’ and employees’ adoption of western HRM and western management ideas, knowledge, and practices; any change in strategies, policies, and procedures; and problems in their implementation.

The aim of the diploma thesis is to introduce suitable instruments for measuring the market position of the company based on multi-criteria decision-making. To introduce regular rankings of companies in professional journals and on the Internet. The main aim was to make comparison of five companies in the Czech Republic and build their resulting ranking based on financial and non-financial indicators. Selected companies have the same subject of business, form and size. For comparison there was set a model which included four financial and two non-financial indicators. Financial indicators have been selected from the area of profitability, liquidity, aktivity and indebtedness. Afterwards, the market positions of companies were calculated by mathematical-static method. The financial situation was identified also by profit and bankruptcy models.

O objeto de estudo deste trabalho é caracterizar um transdutor magnético de posição absoluto de longo percurso e robusto quanto à sua resposta dinâmica. O transdutor foi concebido na dissertação de mestrado do autor e denominada de ¨Régua Magnética¨na qual foi estudada a sua resposta estática. Diferentemente de outros transdutores magnéticos este tem como princípio de funcionamento a divisão do fluxo magnético entre dois caminhos distintos, cujas dimensões variam em função da movimentação da bobinas de excitação. Neste estudo analisa-se então a resposta dinâmica do transdutor, pois, quando o seu carro se desloca com velocidade constante, há uma modificação na grandeza física que é responsável pelo sinal de saída correlacionado à posição daquele carro. O estudo foi desenvolvido em dois transdutores de aproximadamente 2 m de comprimento confeccionados com lâminas de Fe-Si cortadas a laser. Os sinais de tensão induzida nas culatras, corrente e fluxo magnético no eletro-ímã do carro bem como o sinal de posição deste são coletados por um dispositivo digital e processados em um computador de modo a se poder obter as curvas estáticas e dinâmicas e assim compará-las. Com este propósito, foi desenvolvida uma bancada original de ensaio de transdutores de posição lineares para a medição da diferença dos sinais entre o caso estático e o dinâmico, denominado de diferença dinâmica, na qual foi empregado um transdutor de posição resistivo para a referência de posição, um sistema de aquisição de sinais para a medição das grandezas envolvidas no processo e um conjunto movimentador e servomotor para controle da velocidade e posição da parte móvel do transdutor. No final deste trabalho são comparados os resultados analíticos e experimentais obtidos como antes descritos. / The aim of this work is to characterize a long-span absolute magnetic position transducer that presents a robust dynamic response. The transducer was conceived by the MSc studies of the author and is called named “Magnetic Ruler” by which its static response was studied. Unlike other magnetic transducers, the magnetic ruler is based on the principle of the division of magnetic flux between two distinct magnetic paths that depends on the linear position of its movable part along the span of the transducer. This present study examines the dynamic response of the transducer when its movable part or car is moving with constant speed. Under such conditions, there is a change in the signal output that is correlated to the position of that car. The study was conducted by means of two transducers of approximately 2-m long laminations of Si-Fe that were laser cut. The voltage signals induced through the search coils on the end yokes, current and magnetic flux in the excitation coil on car, and the position are acquired by a digital device and processed by a computer. That is done to obtain the static and the dynamic curves and, thus, to allow the comparison between the two behaviors. With this objective, a specially built and unique test bench was developed to test linear position transducers under static and dynamic cases. The difference between the two results is called dynamic difference. That test bench employs a resistive position transducer to provide position reference, a signal acquisition system for measuring the quantities involved in the process, and a controlled traction system based on a servo system to control the speed and the position of the moving part of the transducer under test. At the end this work the analytical and experimental results obtained as described above are compared.

Sediment and nutrient loss from agricultural landscapes contributes to water quality impairment and has the potential to impact crop yield. Best management practices (BMPs) such as riparian buffers have been designed to combat these issues; however, concentrated flow paths (CFPs) reduce their effectiveness and are often overlooked in agricultural fields. Conventional management of CFPs is to fill and grade them, however this provides only a short term solution leading to their reformation and increased sediment loss. The objectives of this project were: i) to determine if the filling of CFPs influence crop growth (yield and biomass), ii) determine a distance at which crop growth is no longer influenced by CFPs, iii) assess the impact that topography and CFPs have on crop growth, iv) analyze water quality in surface runoff leaving crop fields via CFPs, and v) develop an economic analysis for CFP’s influence on crop returns. Six small agricultural catchments, CFPs, and topographic positions (i.e., depositional, backslope, and shoulder) were delineated using ArcGIS and LiDAR data. In each catchment, six 4 m2 plots were established along CFPs where crop biomass and crop yield were measured. Additionally, six plots with no influence from CFPs were established as reference plots. Surface water quality was assessed by taking edge-of-field grab samples at the CFP outlet during significant rain events (i.e., precipitation exceeding 2.5 cm). Water samples were analyzed for total suspended solids (TSS), total phosphorus (TP), dissolved reactive phosphorus (DRP), ammonium-nitrogen (NH4+-N), and nitrate-N (NO3- -N). Through this study it was shown that CFPs served as a conduit for transporting nutrient and sediment laden runoff to receiving waters, that increasing/decreasing distance from CFPs had an impact on crop yields, and that there was no crop yield advantage from the filling of CFPs vs. leaving them unfilled. Median values for NO3-N (1.85 mg L-1) and TSS (140 mg L-1) in the Fill catchments were higher than the No-Fill catchments (0.77 mg L-1 and 35.5 mg L-1, respectively), while DRP and TP concentrations were higher in the No-Fill catchments (1.31 mg L-1 and 2.37 mg L-1, respectively) compared to the Fill catchments (0.91 mg L-1 and 1.83 mg L-1, respectively) over the growing season. Crop biomass and yield results between the depositional and backslope positions were similar regardless of treatment, but were lower than the reference plots and shoulder position. Results from the economic analysis on the cost of farming in/near CFPs indicated that the economic return was greatly dependent on precipitation. CFPs are generally concave positions on the landscapes and have been eroded to a clayey subsoil, both resulting in greater water accumulation and retention than elsewhere in the field. During wetter years, an economic loss was incurred nearest to the CFP and during drier years, sites nearest to CFPs saw positive returns. Farmers and land managers may consider implementing stabilization measures, such as grassed waterways, in CFPs since crop yields are typically lower in wetter years, there’s increased cost to maintain these areas, and accelerated sediment loss can exacerbate the crop yield losses and impact on water quality.

The importance of the forager palm as one of the most important grass, for your high productivity and quality for the ruminant. However, this research had the objective to evaluate the vegetative growth, production and composition chemistry-bromatologic of the joined forager palm with caja (Spondias spp) in the semi-arid person from the state of Ceará. The experiment was led in the Experimental Farm, in Quixadá, CE in the period from 2003 to 2007, with the planting accomplished in November of 2003 in soil classified like texture Luvissolo Sandy Franco. The experimental desig was randomly blocks with factorial by 2x2x2 with 4 repetitions, with the following treatments: T1 - Plant Sun Not Fertilized east/weast; T2 - Planting Fertilized Sun east/weast; T3 - Plant Sun Not Fertilized Noth/South; T4 - Planting Fertilized Sun North/South; T5 - Plant Shadow Not Fertilized east/weast; T6 - Plant Shandow Fertilized east/weast; T7 - Plant Shandow Not Fertilized North/South; T8 - Plant Shandow Fertilized North/South. In the treatments with manuring 1 kg/cov of tanned bovine manure was placed, corresponding to 20 t / ha. The plant used for the shandow it was the caja (Spondias ssp.), spaced of 7 x 7 m and cup with 1.5 m of height. To accomplish the measures morphometric length, width and thickness used a ruler of 50 cm and a caliper, respectively. During the collection of each plant the cladodes were numbered by order, being the primary cladodes those original of the cladode base, the secondary ones those original of first order and so forth and heavy. Soon after a composed sample was removed to determine the tenors of Fiber in Acid Detergent, Lignina, Ethereal Extract, Crude Protein, ash. For the appraised parameters a variance analysis was accomplished to verify the significant of the factors (sun and shade, east/weast and north/south, fertilized and not fertilized and the interaction among the factors) and the averages compared by the test of Tukey to 5% of probability. Significant effect was verified (P<0.05) for interaction sun/shade and fertilized/not fertilized for the variable length, width, thickness of the cladodes, productivity of the forager palm, ash and total carbohydrates. Already for the Fiber in Acid Detergent verified significant effect (P<0.05) for the interaction sun/shandow and east/weast, north/south. Conclude that in the edafoclimatic conditions where the experiment was lead, the organic fertilization and the plantation in the sun they induce to one better performance of the forager palm (Opuntia fícus-indica (L.) Mill). / No Nordeste brasileiro a eficiência da produção animal foi incrementada ao combinar pastagens nativas e forrageiras adaptadas em conseqüência da baixa produtividade das forrageiras nativas, principalmente na época de estiagem. Tendo em vista a importância da palma forrageira como um dos mais importantes recursos forrageiro, pela sua elevada produtividade e qualidade para os ruminantes. No entanto, essa pesquisa teve o objetivo de avaliar o crescimento vegetativo, produção e composição químico-bromatológica da palma forrageira consorciada com cajá (Spondias spp) no semi-árido cearense. O experimento foi conduzido na Fazenda Experimental Lavoura Seca, em Quixadá, CE no período de 2003 a 2007, com o plantio realizado em novembro de 2003 em solo classificado como Luvissolo de textura Franco Arenosa. O delineamento experimental foi blocos ao acaso com arranjo fatorial 2 x 2 x 2 com 4 repetições, com os seguintes tratamentos: T1 – Plantio Sol Não Adubado Leste/Oeste; T2 – Plantio Sol Adubado Leste/Oeste; T3 – Plantio Sol Não Adubado Norte/Sul; T4 – Plantio Sol Adubado Norte/Sul; T5 – Plantio Sombra Não Adubado Leste/Oeste; T6 – Plantio Sombra Adubado Leste/Oeste; T7 – Plantio Sombra Não Adubado Norte/Sul; T8 – Plantio Sombra Adubado Norte/Sul. Nos tratamentos com adubação foi colocado 1 kg/cova de esterco bovino curtido, correspondendo a 20 t/ha. A planta utilizada para o sombreamento foi a cajá (Spondias ssp.), espaçadas de 7 x 7 m e copa com 1,5 m de altura. Para realizar as medidas morfométricas comprimento, largura e espessura utilizou uma régua graduada de 50 cm e um paquímetro, respectivamente. Durante a coleta de cada planta os cladódios foram numerados por ordem, sendo os cladódios primários aqueles originários do cladódio base, os secundários aqueles originários de primeira ordem e assim sucessivamente e pesados. Em seguida foi retirada uma amostra composta para determinar os teores de Fibra em Detergente Ácido, Lignina, Extrato Etéreo, Proteína Bruta, Resíduo Mineral. Os dados obtidos foram submetidos a análise de variância para verificar a significância dos fatores (sol e sombra, leste/oeste e norte/sul, adubado e não adubado e a interação entre os fatores) e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Foi verificado efeito significativo (P<0,05) para interação sol/sombra e adubado/não adubado para as variáveis comprimento, largura, espessura dos cladódios, produtividade da palma forrageira, resíduo mineral e carboidratos totais. Já para a Fibra em Detergente Ácido foi verificado efeito significativo (P<0,05) para a interação sol/sombra e leste/oeste norte/sul. Conclui-se que nas condições edafoclimáticas em que foi conduzido o experimento, a adubação orgânica e o plantio no sol induzem a um melhor desempenho da palma forrageira (Opuntia fícus-indica (L.) Mill).

Reliable estimates for differences in life expectancy (LE) by socio-economic position (SEP), that can be assessed in an international context and are comprehensive in terms of considering different SEP dimensions, are missing for the German population so far. The aim of the present study is to fill this gap by providing estimates for differences in LE by education, household income, work status and vocational class. The lack of national mortality data by SEP required an innovative methodological approach to estimate LE from survey data with a mortality followup. The main strengths of the method are the low demand on the data, its simple applicability and the estimation of a set of age-specific probabilities of dying. We employed the method to the German Life Expectancy Survey and estimated period life tables for 45 male and 32 female SEP subpopulations. The results show striking differences in LE across all analysed SEP indicators. Among men, LE at age 40 ranges by more than five years between the lowest and highest household income quartiles, more than six years between individuals with low and high education, around ten years across the work status groups, and almost 15 years across the vocational classes. The proportion of those who reach the classic pension age of 65 years also varies considerably, as does the remaining LE at this age. The corresponding differences among women are smaller, yet still notable. The results yield an interesting finding for the ongoing discussion about the various consequences of an increased pension age. Moreover, they provide policy-makers, doctors, researchers and public health workers with insights into Germany's most disadvantaged SEP subpopulations and the potential extent of their disadvantages in terms of longevity and mortality.
