This thesis attempts to demonstrate how the British Government, through the creation of the South Persian Rifles (1916-1921) tried to protect their interests in south Persia, in the special circumstances of the outbreak of World War I, with the official sanction of the Persian Government. The account is given of the origins of the force, of the differences of opinions on its aims and objectives, of its organisation and strategy, its operations and other activities mainly in Fars. The "Sipahdär" agreement of August 1916 is treated in some detail and the relevance of the non-recognition of the force to the subsequent tribal uprisings and disturbances in Fars is examined. Lastly, the significance of the role of the South Persian Rifles is assessed in the light of the 1919 agreement and the aftermath of war, as well as the force's contribution to internal developments. An attempt has been made to discuss these issues as much from the point of view of the different departments of the Imperial and Indian Governments, as from the Persian standpoint. Events in the south have been treated more fully than hitherto from the perspective of internal Persian history

Mestrado, Enfermagem Médico-Cirúrgica - Enfermagem Nefrológica, 2014, Escola Superior de Enfermagem de LisboaA lesão renal aguda (LRA) no pós-operatório de cirurgia cardíaca representa um desafio frequente para as equipas multidisciplinares, assumindo taxas de incidência variáveis, entre os 3% (Bove et al, 2004) e os 43% (Lombardi & Ferreiro, 2008). A definição de LRA não é unânime, persistindo grande variabilidade nos critérios utilizados, mantendo taxas de incidência díspares, mas elevadas. O sistema de classificação RIFLE permite uma clara definição e estratificação, assumindo-se com um instrumento válido no diagnóstico de LRA. A LRA aumenta o impacto das co morbilidades, o tempo de hospitalização e os custos associados. Cabe aos enfermeiros assumir uma atitude preventiva e implementar instrumentos preditores de risco, como garante da melhoria da qualidade dos cuidados. No âmbito do quadro de competências do enfermeiro especialista e decorrente do percurso desenvolvido no contexto dos ensinos clínicos promovemos a sensibilização dos profissionais para a especificidade da pessoa com alteração da eliminação renal. Em particular, delimitados pelo tema em questão, centramo-nos na pessoa submetida a cirurgia cardíaca em risco de desenvolver LRA no período pós-operatório. A partir dos resultados obtidos podemos afirmar que esta complicação é frequente e repercute-se nos resultados em saúde, nomeadamente nas taxas de mortalidade, na qualidade de vida e no aumento do tempo de internamento. Pretendemos assim evidenciar a necessidade de uma intervenção preventiva dos enfermeiros face ao risco de desenvolvimento de LRA no período pós-operatório. E, quando presente a necessidade de uma adequação técnico científica que permita uma abordagem uniforme nos cuidados à pessoa a experienciar esta transição. Como principal contributo deste percurso resultou a proposta de implementação do sistema de classificação RIFLE na Unidade de Cuidados Intensivos, (UCI) de Cirurgia Cárdio-Torácica, como instrumento para a prevenção e diagnóstico de LRA. Em síntese este percurso resultou no desenvolvimento de competências técnicas, científicas e relacionais específicas do Enfermeiro especialista em enfermagem médico-cirúrgica – área específica de intervenção: enfermagem nefrológica, orientados para área temática da LRA

With no significant changes in the design of rifle ranges in more than 100 years, the current range systems are not keeping pace with technological advancements. The Marine Corps rifle ranges are manpower and material intensive, requiring unit commanders to lose personnel to the training evolution for extended periods of non-productive time. Manual target operation, excessive transition time, and extra duties all contribute to eight to ten hours per day to accomplish one hour of live-fire training per individual Marine. Marines must remain at the range to act as scorekeepers, target makers, and/or target operators when not assigned to shoot. The design and implementation of an automated range system with capabilities specifically designed to operate, score, mark, and maintain targets would reduce the non-productive time a Marine spends on the rifle range. Results from this comparative analysis indicate that the automated range would reduce man-hours by seventy-five percent. Furthermore, the implementation of computer technology will enable instructors and shooters to better analyze each training evolution.

Approved for public release; distribution is unlimitedIn 2009, the Commandant of the Marine Corps declared energy a top priority and created the U.S. Marine Corps (USMC) Expeditionary Energy Office to develop an energy strategy to reduce and optimize energy usage throughout the Marine Corps. This thesis examines the operational tasks and capabilities that drive the current USMC rifle platoon’s energy burdens using an Expeditionary Warrior 2012 war-game scenario. The primary conclusion of the research is that increasing the platoon’s ability to carry supplies and developing standardized, rechargeable batteries offers the USMC opportunities to reduce energy at the platoon level. This thesis recommends that the USMC should investigate the use of robotic transport systems and use of unmanned aerial vehicles to reduce the number of sustainment flights required of large aircraft. It also recommends further research should be conducted to calculate the energy usage at the company level, analyzing robotic solutions and standardized batteries to reduce energy at the platoon level and conducting analysis for water reduction.

An alternate method for mitigating the depredating physiological affects of a soldiers marksmanship due to combat stressors can be achieved through the design and implementation of a active stabilization system for small arms weapons. The INSTAR system is an innovative active stabilization system designed to decouple the shooterâ s disturbance effects from the barrel movement. The INSTAR system uses an piezoelectric actuator separating the barrel of the rifle from its stock to stabilize barrel movement. This paper uses various control techniques to develop control algorithms for simulation. The level of performance for each control algorithm is based on how well each they measure up to the criteria developed from the INSTAR system. This paper furthers research on INSTAR by developing and comparing four control designs that may be implemented within the INSTAR system.Master of Science

This CAPSTONE Report documents the Systems Engineering (SE) efforts of "Team Marine," from JAN 2009 to SEP 2009, in developing a recommendation to the US Marine Corps Systems Command (MCSC), on the best course of action to 'Enhance the USMC Expeditionary Rifle Squad Communications System.' The squad leader is the cornerstone for USMC tactical operations. Clear, concise, accurate and reliable communications to and from the squad leader is the key to squad operations, performance and tactical effectiveness. Today's fielded communications system for the squad leader requires the use of two separate radios, each with different encryption algorithms, different user interfaces, and different data processing capabilities. This primitive design has thrust the squad leader into a complex Human Factors environment with disparate components that have not been well engineered or integrated. Team Marine applied and tailored the systems engineering (SE) process based on NPS course work and professional experience. This SE process enabled the team to completely understand and model the current system in terms of architecture, capabilities and functions. The process led the team and stakeholders to conclude that an evolutionary approach of system integration was preferred over the traditional Manufacturer A vs. Manufacturer B run off. The team's recommendation is to pursue an integrated communications system, based on existing and emerging components, as the best course of action. The first incremental step of the recommendation is to upgrade the existing elements by adding an automated communications processor with enhanced human to system interfaces.

Using familiar rhetorical tropes, they marshaled their supporters and presented a violent resistance to the transformation of the American state. Railing against perceiving conspiracies involving Judaism, Communism, and international banking, these men set a precedent for extreme right-wing politics that resonated in their own time and still has consequences today

Der volle Inhalt der QuelleAnnotation:
This study aims at evaluating the clinical outcomes with the use of Polymyxin B, antibiotic that is being increasingly used across the current needs of antimicrobial therapy. Was developed in the 40s for the treatment of gram-negative bacilli, and fell into disuse because of its toxicity, mainly renal. Despite this increased use is poorly understood its true efficacy and its toxicity profile (ZAVASCKI et al., 2010, p.71). Among the clinical outcomes analyzed the mortality at 30 days and the occurrence of acute kidney injury (AKI). This evaluation was made by means of a retrospective cohort study, based on data collection from medical records of adult patients admitted to the University Hospital of Santa Maria (HUSM), who received Polymyxin B for more than 48 hours. For evaluation of the nephrotoxicity RIFLE criteria were used. The diagnosis of infection was made according to the criteria of the National Health Surveillance Agency (Anvisa). We evaluated 53 patients, mean age 56 years, 29 (55%) men and 24 (45%) women. AKI occurred in 25 (53%) participants, with an average start of 8.5 (± 4.9) days. In thirty days, 12 (48%) patients showed improvement of renal function to pretreatment levels. Doses above 25 mg / kg / day and previous normal renal function, doses were positively correlated with worsening kidney. Regarding the clinical outcome observed that 29 (55%) had a favorable outcome at 14 days. Eighteen (34%) participants died within 30 days after initiation of treatment. As risk factors for death were found combined use with other active drug to BGN resistant to carbapenems (p-value 0.028, RR 13 CI 1.3 to 130), and SOFA score greater than eight (p-value <0.029, RR 1.3 CI 15 to 179). The conclusion is based on these findings, the mortality related to use of Polymyxin B is dependent on the degree of comorbidities presented by the patient (SOFA) and the use or not of combination therapy. This last finding may be due to a bias of severity of infection. When it was found that nephrotoxicity is an agent with nephrotoxic potential, and that the occurrence of AKI is influenced by the prescribed daily dosage. The fact of the LRA have been more frequent in patients without renal injury corroborates the hypothesis that greater care with other causative factors for AKI may decrease its occurrence in patients using polymyxin B.Este estudo tem como objetivo a avaliação dos desfechos clínicos com a utilização da Polimixina B, antibiótico que vem sendo cada vez mais utilizado frente às necessidades atuais de terapia antimicrobiana. Foi desenvolvido na década de 40 para o tratamento de bacilos gram-negativos (BGN) e, entrou em desuso devido a sua toxicidade, principalmente renal. Apesar deste crescente uso permanece pouco entendidos a sua real eficácia e seu perfil de toxicidade (ZAVASCKI et al., 2010, p.71). Dentre os desfechos clínicos analisados incluíram-se a mortalidade em 30 dias e a ocorrência de lesão renal aguda (LRA). Essa avaliação foi feita por meio de uma coorte retrospectiva, baseada na coleta de dados do prontuário médico de pacientes adultos, internados no Hospital Universitário de Santa Maria (HUSM), que receberam Polimixina B por mais de 48 horas. Para avaliação da nefrotoxicidade foram utilizados os critérios Risk Injury Failure Loss Endstage renal disease(RIFLE). O diagnóstico das infecções foi feito conforme os critérios da Agência Nacional de Vigilância Sanitária (ANVISA). Foram avaliados 53 pacientes, com idade média de 56 anos, sendo 29 (55%) homens. Ocorreu LRA em 25 (47%) participantes, com média de início de 8,5 (±4,9) dias. Em trinta dias, 12 (48%) dos pacientes apresentaram melhora da função renal a níveis pré-tratamento. Doses superiores a 25 mg/Kg/dia e função renal prévia normal, tiveram correlação positiva com a piora renal. Quanto ao desfecho clínico observamos que 29 (55%) tiveram um desfecho favorável em 14 dias. Dezoito (34%) participantes faleceram em 30 dias após o início do tratamento. Como fatores de risco para o óbito foram encontrados o uso combinado com outra droga ativa para BGN resistente à carbapenêmicos (p-valor 0,028, RR 13 IC 1,3-130), e escore SOFA superior a oito (p-value <0.029, RR 15 CI 1,3 to 179). Conclui-se com base nesses achados, que a mortalidade relacionada com uso da Polimixina B é dependente do grau de co-morbidades apresentado pelo paciente (escore SOFA) e do uso ou não de terapia combinada. Podendo esse ultimo achado dever-se a um viés de gravidade da infecção. Quando a nefrotoxicidade encontrou-se que é um agente com potencial nefrotóxico, e que a ocorrência da LRA é influenciada pela dose diária prescrita. O fato da LRA ter sido mais frequente em pacientes sem lesão renal prévia corrobora com a hipótese de que um maior cuidado com outros fatores causadores de LRA pode diminuir sua ocorrência em pacientes que utilizam Polimixina B.

Approved for public release; distribution is unlimitedWith the increase of the loaded weight that a Marine carries, the integration of robotics is a significant point of interest to the United States Marine Corps, especially to the Expeditionary Energy Office. Through the use of the agent-based modeling and simulation application, Pythagoras, robots are integrated into a Marine Expeditionary Unit’s rifle platoon to alleviate the burden on each Marine. This study examines the rifle platoon’s energy and power consumption, operational reach, and operational effectiveness for a scouting and patrolling mission. A systems engineering methodology results in a tradeoff analysis on the rifle platoon’s success, relative to the number of integrated robots. Integrating six robots in a rifle platoon can improve the platoon’s ability to fulfill its mission, while supporting the Marine Corps’ energy strategy. In the context of energy initiatives, this research forms the baseline for investigating the impact of robot integration in Marine combat operations through simulations.

Background. There are few studies of renal function evaluation in visceral leishmaniasis (Kala-azar). The aim of this study was to investigate the clinical manifest and the risk factors associated with acute kidney injury (AKI) based on RIFLE criteria in patients with visceral leishmaniasis (VL). Methods. A retrospective study of medical records from patients over 14 years old, without previous kidney disease, with VL, treated at SÃo Josà Infectious Diseases Hospital, from 2002 to 2008. Clinical manifestations and risk factors for AKI (defined by using RIFLE criteria) were studied. A multivariate analysis was performed to analyze the risk factors for AKI. Results. A total of 224 patients were included. The mean age was 36Â15 years and 76.8% were males. AKI was observed in 76 patients (33.9% of cases) and % 52.6 (40) were class F on RIFLE criteria. The main clinical symptoms were dyspnea, edema and jaundice in patients with VL and AKI (p<0.05). Oliguria was observed in 6.5% of patients with AKI. Risk factors associated with AKI were male gender (OR=2.2, 95% CI= 1.0-4.7, p=0.03), age > 40 years (OR = 1.05, 95% CI= 1.02-1.08, p < 0.001) and jaundice (OR=2.9, 95% CI= 1.5-5.8 p=0.002). There was an strong association between amphotericin B use and AKI (OR=18.4, 95% CI=7.9-42.8, p<0.0001), whereas glucantime use was associated with a lower incidence of AKI when compared to amphotericin B users (OR=0.05, 95% CI=0.02-0.12, p<0.0001). Mortality was 13.3% and it was higher in AKI patients (30.2% vs. 4.7%, p<0.0001). RIFLE criteria presented mortality 40%, 20.8% e 35% in R, I and F respective class. Conclusions. The risk factors associated with AKI in patients with VL were male gender, advanced age, jaundice and amphotericin B. The last one was the most important factor of AKI in VL.IntroduÃÃo. Hà poucos dados na literatura que relacionam a Leishmaniose visceral (LV) à lesÃo renal aguda (LRA). O objetivo deste estudo à avaliar as manifestaÃÃes clÃnicas e fatores de risco associados à LRA em pacientes com LV e aplicar o critÃrio RIFLE. MÃtodo. Estudo retrospectivo, incluindo pacientes acima de 14 anos, sem doenÃa renal prÃvia, com diagnÃstico de LV, internados no HSJ entre 2002 e 2008. Foram avaliadas manifestaÃÃes clÃnicas e os fatores de risco relacionados à LRA (avaliada atravÃs do critÃrio RIFLE) nesses pacientes, aplicando regressÃo logÃstica multivariada. Resultados. Foram incluÃdos 224 pacientes com idade mÃdia de 36Â15 anos sendo 76,8% do gÃnero masculino. LRA foi observada em 76 pacientes (33,9%) sendo que 52,6% (40) estavam na classe F do critÃrio RIFLE. Dispneia, edema e icterÃcia foram os principais sinais e sintomas associados à LRA (p<0,05). OligÃria foi observada em 6,5% dos pacientes com LRA. Os fatores de risco associados à LRA foram gÃnero masculino (OR=2,2, 95% IC=1,0-4,7, p=0,03), idade acima de 40 anos (OR = 1,05, 95% IC = 1,02-1,08, p<0,001) e icterÃcia (OR=2,9, 95% IC=1,5-5,8, p=0,002). Foi verificada considerÃvel associaÃÃo entre o emprego de anfotericina B e LRA (OR=18,4, 95% IC=7,9-42,8, p<0,0001), contudo o uso de glucantime foi associado a menor ocorrÃncia de LRA (OR=0,05, 95% IC=0,02-0,12, p<0,0001). A mortalidade geral foi 13,3% e foi mais alta nos pacientes que desenvolveram LRA (30,2% vs. 4,7%, p<0,0001). Os percentuais de mortalidade nas classes R, I e F foram respectivamente 40%, 20,8% e 35%. ConclusÃes. Os fatores de risco preditores de LRA em pacientes com LV foram sexo masculino, anfotericina B, idade acima de 40 anos e icterÃcia. Anfotericina B foi o fator mais importante de LRA na LV.

A classificação de RIFLE define três classes de severidade da Lesão Renal Aguda (LRA): Risco, Injúria e Falência. A severidade da LRA foi associada à mortalidade. Entretanto, se a classificação de RIFLE melhora o desempenho do APACHE II na predição de óbito em pacientes críticos não é conhecida, além de pouco avaliada em estudos prospectivos. Objetivo: Analisar se a classificação de RIFLE agrega valor ao desempenho do escore APACHE II na discriminação da mortalidade em pacientes criticamente enfermos e avaliar prospectivamente a associação do RIFLEmáximo Injúria+Falência com a mortalidade nessa população. Metodologia: Estudo observacional de coorte prospectiva de 200 pacientes admitidos na UTI, de julho/ 2010 a julho/ 2011. Resultados: A idade da amostra analisada foi de 66 (±16,7) anos, 53,3% do sexo feminino. A mortalidade geral na UTI foi 25,5%. O APACHE II apresentou estatística-C de 0,75 ± 0,038 (IC 95%: 0,68-0,80 P=0,001) e 0,80 ± 0,034(IC 95%: 0,74-0,86 P=0,001), após incorporado à classificação de RIFLE, em relação a predição de óbito. A comparação entre as AUROCs, P=0,03. Observou-se que 40% dos pacientes classificados inicialmente como Risco progrediram. A mortalidade foi de 53,3% versus 4,4% nos subgrupos com LRA RIFLEmáximo Injúria+Falência e Sem LRA+RIFLEmáximo Risco, respectivamente. O RIFLEmáximo Injúria+Falência foi associado à mortalidade após ajustes para outras variáveis (OR:13 IC95%: 4,57-37,6 P=0,001).Conclusão: A gravidade da LRA, definida pela classificação de RIFLE foi um marcador de risco para mortalidade em pacientes criticamente enfermos, e melhorou o desempenho do escore APACHE II na discriminação da mortalidade nessa população. O RIFLEmáximo Injúria+Falência apresentou maior risco de morte quando comparado à aqueles que permaneceram na classe Risco ou que não desenvolveram LRA.

This thesis is concerned with the design and development of British infantry rifles. The specific weapons considered are the Lee-Metford (LEME) first introduced in 1888; the Short Magazine Lee-Enfield (SMLE) brought into service in 1904; the Experimental Model No. 2 (EM2) briefly designated the Rifle No. 9 MkJ in 195 1; and the Section Small Arms Post 1980 (SA80) issued to troops in 1986. Over the past twenty years academic literature has demonstrated that technological determinism has persistently crept into accounts of technical change. By consistently leaving human agency out of the equation, technology has appeared to evolve autonomously and to have determinate effects. Whilst studies of civilian technologies have shown that this way of seeing has serious flaws, very little has been undertaken to show how the same issues arise in a military context. The approach adopted here explicitly aims to highlight and avoid problems of technological determinism by putting human choice back into the story of British rifle design. This is achieved through the identification of key personalities and social groups who had a perspective on, and an interest in, the development of the various systems. Having identified the key actors, their views on each artefact are explored. What emerges is that different groups see a particular technical solution differently. The arguments about what must be included in, and what is irrelevant to, a design of rifle are as a result exposed for further examination. The eventual weapon that emerges from these debates can be seen as a negotiation among the various parties: an artefact around which various perspectives coalesce. What transpires is a detailed picture of the tactical problems each weapon attempts to resolve. This not only indicates how various groups see the battlefield problem but also describes how these same actors want the infantry to fight. -

Der volle Inhalt der QuelleAnnotation:
The alternation of bathymetrlc lows (pools) and highs (riffles) along a stream plays a critical role in ecology. Besides providing a diversity of substrate material and local flow velocities, pool-riffle sequences (PRS) influence the living conditions in the near-stream sediments by inducing an infiltration of surface water Into the subsurface and a delayed exfiltration back to the stream. This process, called hyporheic exchange flow (HEF). supplies oxygenated water to subsurface organisms and has the potential to modify the chemical composition of stream water. Although PRS-induced HEF is to some degree predictable, little is known about its potential variability in time, space, and across scales. The research reported here investigates this gap through field experimentation in low flow conditions, and numerical modelling. First flow characteristics are detailed through extensive in situ measurements conducted at the metre-scale, and across a range of temporal resolutions. The geometry of the subsurface flow systems, residence time distributions, and fluxes are then estimated through three-dimensional groundwater modelling. Using these models, a sensitivity analysis is performed to characterize the influence of identified controls on HEF characteristics. Finally through a hypothetical 2·D model of a pool-riffle sequence, we evaluate the consequences of Ignoring small scale exchange flow induced by current-obstacle interactions, in channel-unit scale models. This study was conducted at the River Leith, a third-order stream situated within the Eden catchment, in the north west of England. The field site is located in the lower part of the catchment, and belongs to a three kilometre stretch that is known to be significant1y groundwater-fed by the underlying Permo-Trlassic sandstone. In summer, the stream's discharge can be as low as 0.03 m3 S -l. The 200 m study reach includes a succession of three pool-riffle sequences, located along a meander. The streambed consists primarily of gravels and cobbles. The first study examines at a high spatial and temporal resolution the variability of hydraulic conductivity (K), vertical hydraulic gradients (VHGs), and subsurface fiuxes, over a single riffle- step-pool sequence. A 20 m reach was equipped with a network of piezometers in order to determine the distribution ofVHGs and K. During a summer month, temporal variations ofVHGs were regularly surveyed and, for a subset of piezometers, the water level was automatically recorded at 15 min intervals by logging pressure transducers. Additionally, point-dilution tests were carried out on the same subset ofpiezometers. Whereas the distribution of vertical fluxes can be derived from K and VHG values, point-dilution tests allow for the estimation of horizontal fluxes where no VHG is detectable. Results indicate that, spatially, VHGs switched from upwelling to downwelling across lateral as well as longitudinal sections of the channel. Vertical fluxes appeared spatially more homogeneous than VHGs, suggesting that the latter can be a poor indicator of the intensity of flow. Finally, during flow events (high flows), some VHGs showed little or no fluctuations. This was interpreted as the result of a pressure wave propagating from upstream through highly diffusive alluvial sediments.

Today, the strength of the National Rifle Association (NRA) is understood by the general public and many scholars to be dependent on the Second Amendment of the U.S. Constitution, the right of individuals to own firearms. This dissertation challenges that understanding by focusing on three organizations, the NRA, the National Guard and the National Board for the Promotion of Rifle Practice (NBPRP). While each organization appears in today's world to be distinct and independent, this dissertation reveals how they garnered strength from a symbiotic relationship. The NRA was founded in 1871, originally as a marksmanship organization. The National Guard, which grew from the nation's militia, was formally established in the early twentieth century. The NBPRP was a small organization that was established in 1903 within the War Department at the encouragement of the NRA.
Following passage in 1903 of legislation bringing state militia units under federal control, the newly formed National Guard became dependent on the NRA, which in turn leveraged that dependence to create a nationwide grassroots organization. The NBPRP was headed by the Assistant Secretary of War until 1916 when the position of the Director of Civilian Marksmanship was created, to be held by a U.S. Army or U.S. Marine Corps officer. The NRA acted as the surrogate of the NBPRB outside of the halls of government. At the same time, the NBRPB provided the NRA with a voice within those same halls that aided in the development of federal policy and budget positions related to firearms acquisition, competition, and training.
The purpose of this dissertation is to reveal how the NRA was able to employ these two organizations to develop an exceptionally powerful grassroots organization that today is recognized as one of the most powerful special interest groups in America. Understanding how this powerful organization grew offers one perspective of how the bureaucracy that has been developed to support America's federal system of government is uniquely susceptible to special interest influence.

Hydraulic and morpho-sedimentary differences between pools and riffles have always intrigued fluvial geomorphologists. Surprisingly, earlier explanations of pool-riffle morpho-sedimentology dynamic focus too exclusively on hydraulic patterns and neglect analysis of sediment transport. Understanding the mechanisms governing pool-riffle morpho-sedimentary dynamics, such as the sediment transport patterns represent a big challenge in fluvial geomorphology, considering the stochastic nature of bedload transport in gravel-bed rivers. The main objective of this thesis is to understand the two-dimensional relationship between hydraulic patterns, sediment transport patterns and morpho-sedimentary changes in pool-riffle sequences and to use these insights to understand how pool-riffle sequences maintain their form over time.This thesis is organized into four chapters. These chapters analyze hydraulic, sediment transport and morpho-sedimentary measurements collected on a riffle-pool-riffle sequence of the Des Coeurs river during seven controlled experimental floods. Chapter 2 tests the velocity reversal hypothesis (Keller, 1971), with results demonstrating that no velocity reversal was observed in the field, for peak flow up to 123% of the bankfull discharge. Chapter 3 demonstrates the existence of a bedload transport reversal: below 60% of bankfull discharge, sediment transport on the riffle exceeds transport in the pool; as discharge increased, more sediment was exported from the pool than imported, thereby maintaining the pool. Chapter 4 demonstrates that the bedload transport reversal is caused by the spatial heterogeneity of the sediment transport patterns (sediment supply, particle displacements and sediment sorting), which underlies the importance of developing two-dimensional bedload transport formulae. Chapter 5 tests the two-dimensional applicability of well-known bedload transport formulae developed in a one-dimensional environment. None of the formulae could be applied with accuracy in a two-dimensional environment. However, site-specific calibration considerably improves bedload transport rate and grain-size distribution prediction.
This thesis improves the understanding of the morpho-sedimentary dynamics of pool-riffle sequence; it argues that a purely hydraulic view of pool-riffle sequence is insufficient to understand their stability. It explains pool-riffle maintenance as a result of a bedload transport reversal caused by the spatial heterogeneity of the sediment transport patterns, and raises the importance of acquiring two-dimensional sediment transport data to improve two-dimensional bedload transport formulae.

Das Mahanadi-Rift liegt am Ostrand von Indien und wird innerhalb von Gondwana mit dem Lambert-Rift (Ostantarktika) korreliert. Es war Zielstellung der Arbeit, auf Grundlage einer Satellitenbildauswertung eine Analyse der strukturgeologischen Entwicklung im Umfeld des Riftes vorzunehmen. Ausgehend von der Satellitenbildinterpretation wurden neben strukturgeologischen Feldarbeiten, geochemische bzw. geochronologische Untersuchungen von basischen Gängen und Pseudotachyliten durchgeführt. Im Ergebnis konnte nachgewiesen werden, dass die während der Grenville-Orogenese angelegten Hauptstrukturelemente um 700 – 750 Ma in einem Extensionsfeld mit Intrusionen von Basiten reaktiviert wurden. Datierungen von Pseudotachyliten belegen semiduktile, panafrikanische Deformationen von 540 – 510 Ma, die vorrangig an WNW streichende Lineamente gebunden sind. Die Beckenanlage beginnt im Unteren Perm mit sinistraler Reaktivierung der North Orissa Boundary Fault. Die nachfolgende Beckenentwicklung bis zum Gondwanazerfall wird durch mehrphasige Extensions- und Kompressionsvorgänge mit variabler Orientierung des Spannungsfeldes bestimmt.

Anonymous communication is an important part of democratic societies and freedom of speech. Whistleblowers, protest organizers, and, more broadly, anyone with controversial viewpoints have been using the limited form of anonymity the Internet provides to protect their privacy. Unfortunately, the basic anonymity the Internet guarantees is too weak to protect their identities from even the weakest adversaries. As a result, more and more users have adopted privacy enhancing technologies to protect themselves. All existing anonymity systems, however, sacrifice anonymity for efficient communication or vice-versa. Onion-routing achieves low latency, high bandwidth, and scalable anonymous communication, but is susceptible to traffic analysis attacks. Designs based on DC-Nets, on the other hand, protect the users against traffic analysis attacks, but sacrifice bandwidth. Verifiable mixnets maintain strong anonymity with low bandwidth overhead, but suffer from high computation overhead instead. In this thesis, we present Riffle, a bandwidth and computation efficient communication system with strong anonymity. Riffle consists of a small set of anonymity servers and a large number of users, and guarantees anonymity as long as there exists at least one honest server. Riffle uses a new hybrid verifiable shuffle technique and private information retrieval for bandwidth- and computation-efficient anonymous communication. We have evaluated Riffle in two different applications: file sharing and microblogging. Our evaluation shows that Riffle can achieve a bandwidth of over 100KB/s per user in an anonymity set of 200 users in the case of file sharing, and handle over 100,000 users with less than 10 second latency in the case of microblogging.

The purpose of this study was to investigate the ergonomics and biomechanics of rifle shooting from the standing position. At present, the scientific literature on shooting contains primarily qualitative descriptions of the various aspects of the sport. Quantitative data on the kinetic and kinematic aspects of standing rifle shooting was collected in the present thesis. Transducers were developed to measure foot forces in the vertical and horizontal plane, recoil force on the shoulder and the grip force of the trigger hand. Kinematic data was collected with a video camera. The study revealed that recoil energy was dependent on the attributes of the shooter. Handgrip forces were found to be well below the maximum handgrip strength. An exploratory investigation of the interrelationships among foot forces, rifle recoil and angular and linear displacements was carried out. No horizontal foot forces to counteract the recoil force were observed. A possible explanation for the finding is proposed. The findings are discussed with reference to the ergonomic implications for rifle stock design. Further investigations of the relationships between shooting performance and the man-rifle interface are indicated.

A geologia das bacias sedimentares tem passado por um processo evolutivo significante nos últimos cinqüenta anos. Os procedimentos analíticos iniciais focavam em metodologias descritivas, definições gerais e padronizações. Isso foi fundamental, para a criação de uma linguagem universal, a qual todos entendessem o que estão falando, representando um avanço crucial. Por conseqüência, a estabelecida metodologia descritiva abriu margem para uma camada superior de análise: a interpretação de processos. Com base nisso, surgiu a estratigrafia de seqüências, que se disseminou, derivou e estabeleceu como um paradigma fundamental na geologia sedimentar moderna. Originalmente, a estratigrafia de seqüências foi desenvolvida para uso especifico em margens passiva. Mas atualmente, a compreensão de bacias do tipo rifte está passando por esta transformação, onde relevam‐se os processos controladores e o cunho genético é o cerne do entendimento. Diversos modelos foram desenvolvidos, principalmente na década de 90 e primeira década do século XXI. Porém, ao longo do desenvolvimento da presente tese, observou‐se que as bacias rifte não podem ser analisadas somente sob um cunho estratigráfico, sendo necessária também uma análise estrutural. Um rifte é o resultado do processo de estiramento de uma crosta (no caso, continental), onde se gera uma depressão (bacia) preenchida por sedimentos. Dada sua natureza mecânica, seu principal controle é estrutural, e sua sedimentação é amplamente controlada pela tectônica. Assim, partindo dos modelos bibliográficos iniciais, foi adaptado e desenvolvido um modelo teórico geral de evolução de bacias rifte, baseado em controles tectono‐estratigráficos sob um enfoque genético. Este modelo é aplicado através dos tratos de sistemas tectônicos, que são unidades genéticas baseadas nos padrões de empilhamento, reconhecíveis em poços, seções verticais de afloramentos e sísmica. As bacias rifte apresentam relações complexas entre suas variáveis controladoras, sendo comum a ocorrência de eventos deposicionais correlatos a discordâncias concomitantes, devido a rotação de bloco no meiográben, o atraso no aporte sedimentar, devido ao pulso tectônico instantâneo e incapacidade de ajuste automático da rede de drenagem, o que acarreta em uma deposição essencialmente fina relacionada ao pulso tectônico, e uma entrada de sedimentos posterior ao pulso. Por fim, o padrão evolutivo de um meio‐gráben faz com que ocorram expansões e retrações na geometria da bacia, o que também acarreta em reajustes da rede de drenagem. Estas relações entre variáveis controlam diretamente os padrões de empilhamento, e o processo de rifteamento desenvolve padrões distintos para cada fase evolutiva, denominadas nesta tese de fases de início de rifte, clímax e final do rifte.The geology of sedimentary basins has gone through an important evolutionary process in the last fifty years. The early analytical procedures focus on descriptive methodologies, general definitions and standardizations. It was fundamental to create a universal language that everyone understood which represents a crucial breakthrough. Consequently, the descriptive methodology established allows a new analytical venture: the interpretation of processes. Based on this, the sequence stratigraphy were developed, which spread, derived and established itself as a fundamental paradigm in modern sedimentary geology. At its origins, the sequence stratigraphy was developed exclusively to passive margin basins. But nowadays, the rift basins have been analyzed based on controlling process and the genetic parameters are in the core comprehension. Several models were developed, mainly at the 90´s and the first decade of the XXI century. However, through the elaboration of the present thesis, were identified that the rift basins cannot be analyzed only by a stratigraphic scope. A rift is the result of a crustal stretching process (in this case, continental crust), which generates a depression (basin) filled by sediments. Due to the mechanical evolution of the rift, the tectonic is the main control, and the sedimentation is wide tectonically controlled. Therefore, based on the bibliographical models, this thesis proposed an adapted and developed theoretical model of evolution of rift basins, based on tectonic‐stratigraphic controllers from a genetic scope. This model is applied based on tectonic system tracts, which are genetic units based on stacking patterns, recognizable on wells, outcrop vertical sections and seismic sections. The rift basins shows complex relationships between its controlling parameters, as the contemporary erosion and deposition, due to block rotation at the half‐graben. Also, the delay of the sedimentary supply, due to the instantaneous tectonic pulse and the inability of rapid adjustment of the drainage net, which results in fine grained sediments related to the tectonic pulse, and a coarse grained sediment input after the pulse. Finally, the evolutionary pattern of a half‐graben controls expansions and retreats of the basin geometry, which also rearrange the drainage net. These parameters relationships controls directly the stacking patterns, and the rifting process develops distinctive patterns for each evolutionary phase, named in this thesis as rift initiation, rift climax and rift ending.

Riffle-pool sequences in gravel-bed rivers provide the template for a number ol fish and invertebrate habitats and their morphological complexities create spatial hydraulic variation over the flow regime that is logistically impossible to measure completely in the field. The mechanisms responsible for riffle-pool maintenance are unclear and despite contributions from many researchers, no conclusive explanation has been developed. There is much debate over the popular velocity reversal hypothesis, where it is generally acknowledged that at low flows the maximum bed shear stress in the channel occurs across the riffle, but at higher less frequent flows areas of maximum bed shear stress can switch to the pool. Sediment interactions control fluvial forms and processes, as such specific analysis of spatial hydraulic patterns in boundary shear stress are required to aid understanding of riffle-pool system behaviour and gain the insight in to the transport capacity that can scour sediment deposited in the predominandy low energy, lower competence pools and thereby provide a mechanism for maintenance ol riffle-pool morphology. Terrestrial LiDAR captures reach scale topographical data to yield a 0.02 m digital elevation model and provides input to three-dimensional computation fluid dynamics software (CFD), where the spatial distribution and area! extent of bed shear stress, surface flow velocities and potential sediment entrainment over the discharge range are investigated for a 188 m gravel-bed reach of Kingsdale Beck, UK. With increasing discharge, spatial distributions of shear stress are revealed, which, until now, have been largely overlooked using previous cross-sectional analysis, highlighting the influence of pool tails as discharge rises. Results show some agreement with past literature on reversal with higher shear stress zones associated with riffles. As discharge increases pools are shown to become more dominant, however the existence of multiple reversals shows that while reversals do occur, they may be short-lived and marginal in magnitude, providing inherent problems with current theory. The overall temporal maintenance of the riffle-pool sequence is more explicitly linked with the long term flow regime, with the flows responsible for moving pool sediment closely confined to near bankfull discharge. Results indicate that potential to entrain sediment from pools occurs only from 85% bankfull. Discharges less than 85% bankfull are suggested to be responsible for maintaining the riffle-pool morphology through flow routing and bed shear stress reversal, however, they are not capable of potentially entraining sediment from the deepest pools. Combined CFD simulations with temporal discharge dominance derived from triangulated rainfall and the Revitalised FSR/FEH rainfallrunoff methodology, highlight the role of rarer more extreme flows in terms of explaining sediment entrainment from pools. At high flow Kingsdale Beck creates a competent sub channel, where a continuous sinuous channel with higher levels of bed shear stress develop with embryonic lateral bars, increasing potential sediment entrainment following the line of thalweg. As flow velocity decreases conventional rifflepool hydromorphology re-establishes and provides a new proposal for the maintenance of a riffle-pool sequence.

This study focuses upon flow hydraulics, sediment transport and riffle-pool maintenance on the River Rede, Northumberland, UK. Analysis of bed structure indicate pools to be coarser than riffles, suggesting these to be zones of maximum tractive force at high flow. Tractive force reversal can be demonstrated using a combination of velocity, shear stress and gravel tracer data, and is therefore advocated as a mechanism for maintaining the riffle-pool form. Three dimensional flow structures are likely to increase the likelihood of reversal in pools situated on bends, which may not always be detected using one-dimensional measures of flow hydraulics. Magnetic tracing and basket trapping techniques were used to provide an insight into rates of movement, accumulation, initial motion criteria and routing, of sand. Sand is transported selectively and is mobilised at between 11-22 Nm⁻². Deposition of sub 2mm material is prevalent on morphological high points (bars/riffle margins), although greatest quantities were routed through morphological lows. Freeze core evidence shows limited intragravel storage. Gravel tracer movements showed evidence of size selective entrainment overall, however hiding effects were also found to be evident at two scales; 30-50mm and 110-140mm (for riffles) and 20- 90mm and 11O-140mm for pool. Slope exponents for log-log relations between scaled grain size (D/D₅₀) versus dimensionless shear stress (Өc) of ≈-0.9 suggest that hiding strongly influences sediment transport. Stream power estimates from pgQs demonstrate a higher threshold for motion for gravel in pools (132 Wm⁻²) compared with riffles (127 Wm⁻²). Differences in initial motion criteria (8e) between riffles and pools were found to be significant (p<0.05), indicating pool sediments to be less mobile than riffle, despite pool sediments being less compact. Reduced mobility of pool bedload sediment results from clasts being sheltered by immobile lag gravel found in the pool. It appears therefore that mobility differences between riffles and pools, related to bed structure, does not explain riffle-pool maintenance on the Rede. Scaled travel distance (L/L₅₀s) for tracers in the reach as a whole showed a convex-up relationship with scaled grain size (D/D₅₀s), demonstrating that for tracer grains progressively coarser than the surrounding D₅₀ surface grains, travel distance drops off rapidly, whereas grains progressively finer than the surrounding clasts, travel further but at a less rapid rate. Furthermore, virtual velocity (V*) of tracer grains showed a positive dependence upon D/D₅₀s. Gravel tracer movement provided important insights into riffle-pool maintenance. Transfer of material through the Rede riffle-pool sequence appeared to be influenced by flow magnitude and duration. For low magnitude high frequency flows below 25% bankfull, intra-unit movement was found to predominate. Medium magnitude and frequency flows (up to 50% bankfull) appeared capable of inter-unit transport; scour from pool troughs and deposition on pool exit slopes I riffle heads, movement of material from riffles to bar edges and from bar to bar. For higher magnitude low frequency flows up to bankfull, there was less scour from pools, and a dominance of bar-to-bar sediment transfer. Limited evidence of sediment routing and deposition in pools suggest these to be scour / sediment source zones only, with supply originating from the bed and outer bank. These data demonstrate the importance of different flow magnitude and frequency in creating / maintaining different areas of the riffle-pool structure.

The aim of this thesis was (i) to develop analytical methodologies and a workflow to identify the ocean-continent transition (OCT) and to locate the continent-ocean crustal and lithosphere boundaries (COCB and COLB) at continental rifted margins and (ii) to apply these methodologies and workflow to six cross-sections of the Northeast Brazilian rifted margin. The six cross-sections were taken from the margin segments Almada-Jequitinhonha, Jacuípe, Sergipe, Alagoas and Pernambuco and were constructed using seismic reflection sections from the borders of sedimentary basins to the oceanic crust. The OCT of the Northeast Brazilian rifted margin is complex due to variable extrusive and intrusive magmatism and antithetic tectonics. COCB locations interpreted on seismic reflection data have been tested with those determined using the analytical methodologies and workflow developed in this study. The workflow comprises: 1) the determination of sediment-corrected basement depth profiles, 2) the analysis of the residual depth anomalies of the oceanic crust and its extrapolation into the rifted margin, 3) the gravity inversion of the Moho with crustal thinning determination and 4) the inversion of lithosphere thinning using subsidence analysis. The calibration of the gravity inversion through the fit of the residual depth anomaly in unequivocal oceanic crust is a new approach to determine the reference Moho depth in areas without seismic refraction data. The Almada-Jequitinhonha OCT corresponds to a region of antithetic faulting and low free-air gravity anomaly. The Jacuípe OCT corresponds to a region of development of normal magmatic addition, expressed in the seismic sections as seaward-dipping reflectors, and has a relatively high free-air gravity anomaly. Although the Jacuípe margin represents a narrow rift, this margin seems to be wider and offshore syn-rift sediments are either not imaged or have been eroded. The Sergipe margin is interpreted as being magma-poor during rifting and evolved to slightly magma rich in the early post-rift. The OCT corresponds to a region of continental crust thinner than the adjacent oceanic crust, with antithetic faulting and a stable free-air gravity anomaly. The Alagoas margin is interpreted as being magma-poor during rifting and evolved to normal magmatic addition in the early post-rift, while the Pernambuco margin is interpreted as being slightly magma-rich. The OCT of both margins corresponds to a region of synthetic and antithetic faulting with a low free-air gravity anomaly. The predicted COCB and COLB locations for each cross-section tend to be similar to each other. Only minor differences between the crustal and lithosphere thinning profiles have been observed. The rifted margin width, measured along the cross-sections, does not vary significantly in the South between Almada-Jequitinhonha and Sergipe North, ranging from 110 to 130 km. While, in the North between Alagoas and Pernambuco it is wider, around 170 km. The Northeastern Brazil margin varies from magma-poor in the Almada-Jequitinhonha region to slightly magma-rich in Sergipe and Pernambuco, both probably affected by the Santa Helena Hot Spot. The workflow developed here can be considered successful in locating the COCB and COLB positions and in identifying the OCT in the cross-sections across the Northeast Brazil margin and can be applied to other rifted margins without seismic refraction data.

A busca incessante por informações a respeito da Formação Sergi - maior reservatório de hidrocarboneto da Bacia do Recôncavo - vem ocorrendo durante décadas. Entretanto, raros são os trabalhos que abordam de forma unificada os seus aspectos sedimentares e tectônicos, tal qual se propõe no presente trabalho. Um estudo integrado deverá trazer informações importantes acerca da evolução tectono-sedimentar da Formação Sergi, inclusive no que diz respeito ao seu posicionamento temporal pré-rifte ou cedo-rifte. Para isso, o estudo proposto analisa as estruturas rúpteis (incluindo campos de paleotensão) e os dados sedimentares (como, por exemplo, determinação de sentidos de paleocorrentes), propondo um modelo esquemático dinâmico da evolução tectono-sedimentar da Fm Sergi em área localizada na borda flexural da Bacia do Recôncavo. As estruturas do embasamento também são analisadas com o intuito de verificar se na arquitetura rúptil da bacia há reflexos de herança do embasamento e a sua influência no arcabouço estrutural da mesma. A Bacia do Recôncavo está inserida no sistema de riftes Recôncavo-Tucano-Jatobá cuja formação está relacionada aos estágios precoces de abertura do Atlântico Sul, sendo preservado como um ramo abortado da margem leste do Brasil, durante a fragmentação do Gondwana. A Fm Sergi é caracterizada como uma sequência flúvioeólica-lacustrina, depositada durante a seção pré-rifte. Existe, predominantemente, um padrão de falha N010º notório na área de estudo, sendo o provável responsável pelo basculamento das S0 e no controle da deposição dos sedimentos (principalmente eólico e fluvial entrelaçado). A interpretação integrada dos dados permitiu verificar que a tectônica exerceu um importante papel durante a deposição da Formação Sergi, visto que, seu sistema eólico e seus canais fluviais entrelaçados tiveram, provavelmente, suas paleocorrentes controladas por rampas de revezamento de pequeno rejeito, caracterizando-a como contemporânea à fase cedo rifte da Bacia do Recôncavo.
ABSTRACT The incessant search for information about the Sergi Formation - the largest hydrocarbon reservoir in the Recôncavo Basin - has been occurring for decades. However, there are few studies that unify their sedimentary and tectonic, as proposed in the present work. An integrated study should provide important information about the tectono-sedimentary evolution of the Sergi Formation, including its pre-rift or early-rift positioning. In order to do so, the proposed study will analyze brittle structures (including paleotension fields) and sedimentary data (such as paleocurrents), proposing a dynamic schematic model of the tectono-sedimentary evolution of Fm Sergi in an area located at the flexural border of the Reconcavo Basin. The basement structures are also analyzed with the purpose of verifying if in the basalt architecture there are reflections of inheritance of the basement and its influence in the structural framework of the basement. The Recôncavo Basin is part of the Recôncavo-Tucano-Jatobá riftes system whose formation is related to the early opening stages of the South Atlantic, being preserved as an aborted branch of the eastern margin of Brazil during the Gondwana fragmentation. Fm Sergi is characterized as a fluoride-Aeolic-lacustrine sequence, deposited during the pre-rift section. There is a predominant N010º fault pattern in the study area, being probably responsible for the S0 tipping and the sediment deposition control (mainly braided fluvial and aeolian). The integrated interpretation of the data allowed us to verify that tectonics played an important role during the deposition of the Sergi Formation, since its wind system and its interlaced fluvial channels probably had their paleocurrent controlled by small reject ramps, characterizing it as contemporary to the early rifte phase of the Recôncavo Basin.

The National Rifle Association (NRA) has dominated the debate over gun rights since the late 1960s. In many ways, its political power is unassailable. However, a historical analysis of the NRA's deeply rooted connection to the operations of the American government proves this has not always been so. This thesis is an examination of the mission and actions of the NRA through the lens of the government's expansion of power during and beyond the Cold War.

The main purpose of this thesis is to see if it is possible to use additive manufacturing(AM) for field repair and maintenance of the assault rifle AK5C, by finding a suitableadditive manufacturing process and make a functional evaluation of the additivemanufactured components: hammer axis, gas cylinder and the magazine follower. TheSwedish Defense Materiel Administration (FMV) is an administration that supplies theSwedish armed forces with materiel. Therefore, it is in their interest to investigate if itis possible to use AM for field repair and maintenance in example Mali or Afghanistan.Based on a survey, and the fact that the components are purelystructural Powder Bed Fusion AM was selected. The hammer axis was made in amargining steel MS1, the gas cylinder in the nickel-alloy called Inconel 718 and themagazine follower was made in a polymer called nylon 12.The functional evaluation of the components took place at Saab in Östersund, whereeach component was placed in the rifle. The rifle was fired 1000 rounds with thehammer axis, 1000 rounds with the gas cylinder and 500 rounds with the magazinefollower. The functional test for the components was successful, there were also nomajor changes in dimensions and weight except for the hammer axis. The diameterfor the hammer axis went from 5,00 mm before the functional test to 4,98 mm afterthe functional test. The microscope images showed thatabrasion had occurred, not only for the hammer axis but also for the magazinefollower, due to friction. Firing speed was also measured and it should be over 600rounds/min, if everything works properly. The hammer axis had a firing speed of 639rounds/min which is good while the gas cylinder only had a firing speed of 595rounds/min. This was because the inner diameter of the cylinder was too big, causinggas leaking and pressure drop inside the gas cylinder.In conclusion, additive manufacturing does allow for fabrication of functional spareparts – at least these evaluated here.

This dissertation analyses the social, cultural and religious outlook of the officers and men of the Rifle Brigade, a regiment of the British army, between 1800 and about 1870, and examines the relationship between that corps and British civilian society. Chapter 1 outlines the structure and military record of the regiment, describes its links into the wider army, and examines the military and non-military careers of Riflemen, and their social backgrounds. Chapter 2 presents evidence for reforming and conservative professional attitudes, and argues for the importance to them of an ideal of regenerated gentlemanliness. Chapter 3 describes the operation of patronage and the links it created with civilian society, and it analyses the views of merit that und~rpinned the system. Chapter 4 brings together evidence for the reading of officers and men, and the theatre they saw and performed themselves. It shows how these acted as a channel for a range of information, ideas and attitudes to enter the regiment from civilian society, and so fostered a shared outlook. Chapters 5 and 6 look at the extent and nature of religious belief among Riflemen, taking into account their backgrounds and subsequent careers, and argue both that Christianity coloured attitudes to a range of conduct, and that Riflemen adhered to forms of institutional and cultural religion that should be set beside personal piety. The conclusion highlights the role of the ideal of gentlemanliness in guiding officers and in shaping a culture shared across ranks and across the civilian-military divide. Two appendices are provided. The first describes the method used for the analysis of officers' careers, and the second is a genealogical table showing their interrelation.

This study was conducted to examine the effects of internal imagery and experiential state on the performance of intercollegiate smallbore rifle shooters. An interaction between internal imagery and experiential state was hypothesized. Subjects included 43 smallbore rifle shooters from 7 universities stratified into 2 groups. Group 1, composed of 23 shooters, received internal imagery instructions and practice time; group 2 received unrelated instructions and an equal amount of practice time. Following the instructional period, a posttest was administered to each group (the NRA/ISU Style 1/2 course on an indoor 50 foot range) and each shooter completed an experiential state measure. Analysis of Variance with repeated measures was utilized to examine Pretest to Posttest score differences. An Alpha level of .05 was chosen as the measure of significance.
Results of this study produced no evidence that internal imagery had a significant effect on shooters' composite performance scores. However, the control group's score was significantly lower than that of the imagery group on posttest prone performance. No significant differences were found in the experiential state scores of those shooters who utilized internal imagery as opposed to those shooters who did not. No significant differences were found between scores of shooters classified into a high experiential state group and those classified into a low experiential state group. No significant interactions were evident between internal imagery and experiential state as measured by posttest composite performance scores.

An assumption in Cognitive Psychology, which has been challenged in recent years, is that the systems responsible for action and perception work independently of one another. These systems work together during conceptual tasks and research has demonstrated that action knowledge can influence performance even when the task is 'action-irrelevant' (Borghi, 2004; Borghi, Flumini, Natraj & Wheaton, 2012; Creem & Proffitt, 2001; Tucker & Ellis, 1998, 2001). However, participants in such tasks are often only asked to make simple category judgements, such as natural versus man made. The research reported in this thesis has shown that, under certain conditions, participants use action knowledge to make 'complex' category choices in an action-irrelevant task. The experimental work has predominantly used the forced-choice triad task to assess the circumstances under which participants categorise objects based on shared actions. The triads were designed with a target object and two choice objects matching on either shared actions (rifle + water pistol), shared taxonomic relations (rifle + sword), or both (orange + banana). The context in which the objects were presented was also manipulated so that the objects were either presented on a white background (context-lean) or being used by an agent (context-rich). Participants were most likely to select the choice object that shared both a taxonomic and an action demonstrating that action has an 'additive' effect in categorical decisions. Presenting the objects being used by an agent in a functional scenario increased the saliency of the shared actions between the stimuli, and participants were more likely to select the action choice. The subsequent experimental work reported in the thesis sought to eliminate potential confounding variables including perceptual features, object typicality and task instructions. What the experimental work presented here has demonstrated is that action can influence decisions on more complex categories, and judgments of similarity. The research has identified three main circumstances under which knowledge of action becomes influential in the triad task designed for the purpose of this research as follows: (i) when it is presented in conjunction with taxonomic information, (ii) when it is presented with a context, and (iii) when participants are first asked to physically interact with the objects.
