This thesis is a study of local rather than national black politics. The participation of Gujaratis, who comprise the largest ethnic minority community in Bolton, in local politics is constrained by their loyalty to Gujarati identities and by racism within political parties. The settlement patterns of Gujaratis in Bolton reflect in part the socio-economic constraints experienced by black immigrants in Britain generally, and in part their allegiance to faction, caste, sect and religious identities. On the basis of some of these social identities have developed organisations which respond to particular social, religious and political needs. These organisations provide the only opportunities for the development of black structures of support and leadership within this large community. Notions of racism are based upon a dialogue between white and Gujarati notions of what is common sense. These notions form the basis of Gujaratis' perceptions of social distances that separate them from others. The core of support for leaders is based upon personal social networks. The social characteristics of these social networks influence the patterns of close friendships between Gujaratis and members of other communities in the town. These patterns show that Gujaratis exclude Gujaratis who belong to other Gujarati religious communities and members of other ethnic communities, black and white, from close friendships. Friendships with those perceived to be social distant are of lower intensity, thus excluding these people from sharing in a common body of Gujarati knowledge. In the context of Bolton these Gujaratis find themselves unable to participate within the formal political hierarchy and decision making arenas. The local Community Relations Council offers Gujarati and other black leaders of organisations a forum within which they can meet with some of the locally and nationally elected political representatives. The debate centres on events, involving Gujarati and other participants, which allow leaders of Gujarati organisations and politicians and other members of the CRC to negotiate the power relations between black and white. However, the consequence is that the Gujaratis are still relegated to the periphery of formal political decision-making arenas.

My study concentrates upon the experiences of cotton workers in Bolton and Oldham during the 1930s and 1940s, using trade union and employers' association archives at Manchester's John Rylands University Library. I also investigate business records, official government papers, newspapers, oral accounts and pictorial evidence. My thesis is organised into five chapters: Labour Shortages and Domestic Recruitment; Labour Shortages and Overseas Recruitment; Working Conditions; Occupational Health; and Factory Discipline. Chapter One investigates the recruitment methods used to encourage men and women into cotton mills, as labour shortages escalated during the 1940s. I examine how gendered notions surrounding male and female employment influenced recruitment campaigns, and how the shortage of women for mill work after the Second World War meant that the government's policy towards female labour differed in Lancashire from the rest of Britain. With the infiltration of women into departments previously dominated by men, I explore the impact upon the gendered division of labour and the tactics employed by male operatives to retain men's status in the mill. The difficulty in attracting British operatives to a declining, yet essential, industry in terms of Britain's post-war economic recovery, led the government to embark upon a recruitment drive overseas. Chapter Two investigates the government's selection of immigrant labour based on stereotypes of suitable racial characteristics. I examine how the government's policy concerning foreign workers was determined by concerns over native workers' reactions to the scheme, and how British operatives' response to immigrants was influenced by the threat they posed to paid employment and to gender, class and national identities. One way of attracting labour was to improve working conditions. Chapter Three looks at changes to working practices and the mill environment, and how these impacted upon gender divisions at work. I examine the link between the provision of new factory facilities, and the reaffirmation of separate sexual identities for men and women working in mixed sex departments. Chapter Four investigates the occupational health aspects of cotton production. I explore the pride associated with the physical characteristics gained from mill work. I also study the impact that the gendered division of labour, and notions regarding the respectable appearance of men and women, had upon the types of illnesses from which they suffered and the treatment they sought. Chapter Five investigates factory discipline, linking skill and gender hierarchies with the ways in which men and women experienced and preformed discipline in the mill. I examine how ideas relating to the appropriate behaviour of men and women affected their reactions towards violence and sexual harassment at work. I also explore how the gendered division of labour determined the different types of discipline used, and the degree of supervision men and women received in the mill. In conclusion, I suggest that men and women's experiences in the cotton mills, and their relationship with colleagues, was not only linked to economic uncertainty, but was also closely connected to perceptions of class, gender and identity at work.

This thesis contains an edition of the Coucher Book of Bolton Priory, an Augustinian house in Yorkshire, together with edited sections of Dodsworth MS 144, like the Coucher Book, a copy of the lost cartulary, and a number of original charters. These documents have been edited in full, with each being preceded by a caption in English together with a date and references to other copies. The edition of the Coucher Book contains notes as to where those sections believed to have been omitted from the cartulary are located in Dodsworth NIS 144. The chapters which precede the edition are intended to give some context to the edition, as well as a brief examination of its contents. The first chapter contains a short history of the Augustinian Order, its development in England, and how Bolton Priory fits into this scheme. Chapter two is concerned with the patrons and benefactors of the priory. It is divided into two sections: the first examines the founders and patrons of the priory and their descendants, whilst the second explores the non-patronal benefactors of the house, with a brief analysis of several of the families who were connected from an early date with the priory, as well as the extent of their support and their motives. The third chapter investigates the estates of the priory and their development. Temporal property is examined first, focussing upon the various types of property acquired, together with its location, and methods of acquisition, and then spiritualities: those churches in which the canons acquired an interest, and to what extent as well as how this was acquired. Finally chapter four examines the lost cartulary and the Coucher Book, exploring their administrative histories, as well as a brief analysis of the charters of the founders and others.

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina DentáriaIntrodução: As discrepâncias dento-dentárias também conhecidas como discrepância de Bolton caraterizam-se por um excesso dimensional relativo da estrutura dentária numa arcada ou segmento de arcada que interferem diretamente com a oclusão. A sua etiologia genética torna-as imprevisíveis e muitas vezes difíceis de identificar. Bolton, preconizou duas razões matemáticas para facilitar o seu diagnostico precoce e assim permitir alcançar uma correta correlação intermaxilar e boa oclusão no final do tratamento. Objectivo: Definir a prevalência da discrepância anterior de Bolton numa população ortodôntica portuguesa, com recurso à análise de modelos. Material e Métodos: A amostra deste estudo abrangeu a análise de 200 pares de modelos iniciais em gesso, obtidos através de impressões em alginato. Foram escolhidos aleatoriamente do arquivo clínico de uma clinica particular entre os anos de 2013 e 2014. Respeitando os critérios de seleção, estudámos 157 pares de modelos válidos, dos quais apenas 147 foram considerados relevantes (uma vez que 10 modelos pertenciam a indivíduos com agenesias dentárias), por cumprirem estritamente os critérios de seleção. Os pacientes tinham idades compreendidas entre os 10 e os 34 anos. Os valores obtidos referentes às medidas mésio-distais dentárias foram utilizados para o cálculo da discrepância do tamanho dentário anterior , de canino a canino, segundo o método proposto por Bolton. Ainda assim, os casos com agenesias dentárias tiveram tratamento estatístico. Resultados: Na amostra global de 157 pacientes (58% do género feminino e 42% do género masculino), obteve-se uma prevalência de agenesias dentárias de 6,37% (2,58% bilaterais, 3,79% unilaterais). Na amostra a considerar (147), 36,73% tinha discrepância de Bolton anterior, com uma média e desvio-padrão da razão de 79,37±2,84 e com uma média em milímetros de 2,12 para o excesso mandibular e de 2,26 para o excesso maxilar. Esta é independente do género (p=0,493) e das classes dentárias (p=0,734). O tamanho mésio-distal dentário é maior nos homens que nas mulheres à exceção dos incisivos laterais superiores (12 (p=0,099), 22 (p=0,968)) e dos incisivos centrais inferiores (31 (p=0,094) e 41 (p=0,932)); o tamanho médio encontrado para os 8 incisivos foi de: 6,80±0,52 (12); 8,79±0,57 (11); 8,78±0,55 (21); 6,77±0,53 (22); 6,09±0,39 (32), 5,59±0,35 (31), 5,60±0,36 (41) e 6,12±0,39 (42). Os dentes que apresentaram maior variabilidade de tamanho foram os quatro incisivos maxilares e os seis dentes mandibulares. Conclusão: Numa população ortodôntica portuguesa de 157 indivíduos, 6,37% apresentavam agenesias dentárias. A prevalência da discrepância anterior foi de 36,73% (1,36% com excesso maxilar e 35,37% com excesso mandibular). Esta é independente do género e classe dentária. Os incisivos que apresentaram maior variabilidade de tamanho foram o 21 (p<0,002), 32 (p<0,005), 31 (p<0,008), 12 (p<0,014), 22 (p<0,018) Os resultados obtidos vão de encontro a outras publicações sobre o tema. Introduction: The tooth-tooth discrepancies also known as Bolton discrepancy feature by a relative excess dimensional structure of a dental arch or arch segment that directly interfere with the occlusion. Its genetic etiology makes them unpredictable and often difficult to identify. Bolton, called for two mathematical reasons to facilitate their early diagnosis and thus bring about a correct intermaxillary correlation and good occlusion at the end of treatment. Aim: To define the prevalence of Bolton discrepancy in Portuguese orthodontic population, using the analysis models. Methods: The sample of this study included the analysis of 200 pairs of initial plaster models obtained through impressions in alginate. Were randomized clinical file a private clinic between the years 2013 and 2014. Respecting the selection criteria, we studied 157 pairs of valid models, of which only 147 were considered relevant (since 10 models belonged to individuals with tooth agenesis ), by strictly complying with the selection criteria. The patients were aged between 10 and 34 years. The values obtained on the mesiodistal dental measurements were used to calculate the discrepancy of the previous tooth size canine to canine, according to the method proposed by Bolton. Still, cases with dental agenesis had statistical treatment. Results: In the overall sample of 157 patients (58% female and 42% male gender), obtained a prevalence of tooth agenesis of 6,37% (2.58% bilateral, unilateral 3.79%). The sample to consider (147), 36.73% had anterior Bolton discrepancy, with a mean and standard deviation of 79.37 ± 2.84 ratio and with an average of 2.12 millimeters for the mandibular excess and 2.26 for the maxillary excesso. This is regardless of gender (p = 0.493) and dental classes (p = 0.734). The dental mesiodistal size is larger in men than in women except for the upper lateral incisors (12 (p = 0.099), 22 (p = 0.968)) and lower central incisors (31 (p = 0.094) and 41 (p = 0.932)); the average size found for 8 incisors was 6.80 ± 0.52 (12); 8.79 ± 0.57 (11); 8.78 ± 0.55 (21); 6.77 ± 0.53 (22); 6.09 ± 0.39 (32) 5.59 ± 0.35 (31) 5.60 ± 0.36 (41) and 6.12 ± 0.39 (42). Teeth that have greater variability in size were the four maxillary incisors and the six mandibular teeth. Conslusion: A Portuguese orthodontic population of 157 individuals, 6,37% had dental agenesis. The prevalence of anterior discrepancy was 36.73% (1.36% with maxillary excess and 35.37% with mandibular excess). This is independent of gender and dental class. The incisor that have greater variability in size were 21 (p <0.002) 32 (p <0.005) 31 (p <0.008), 12 hours (p <0.014) 22 (p <0.018) The results go against the other publications on the subject.

Conforme van pasando los años y la práctica ortodóncica cobra popularidad, los profesionales tienen una mayor necesidad de tener la certeza de que los métodos diagnósticos que utilizan en la práctica diaria les brindarán datos confiables y adecuados para la población a la que prestan atención, facilitando el tratamiento. Esta duda parece estar fundamentada en las muchas investigaciones que se han estado realizando a lo largo del tiempo.
En el área de ortodoncia, el diagnostico, etapa inicial, es tal vez una de las etapas más importantes de todo el tratamiento ortodóntico, determinando su éxito o fracaso. El tratamiento de ortodoncia se divide en fases, y cada una presenta características propias y desafíos únicos. La fase de finalización se asocia con muchas dificultades, las discrepancias de tamaño dentario suelen ser una de estas dificultades más frecuentes que muchas veces al estar presentes impiden terminar el caso con una oclusión óptima, intercuspidación ideal con engranaje perfecto, resalte y la sobremordida dentro de los rangos de normalidad. Por tal motivo, el profesional debe estar al tanto de las discrepancias en el tamaño de los dientes en su diagnóstico inicial y en las etapas de planificación, para obtener resultados óptimos en el acabado del caso.
Así pues, un equilibrio debe existir entre el tamaño mesiodistal de los dientes de los arcos superiores e inferiores para garantizar la correcta oclusión en la realización de tratamiento de ortodoncia. El método de Bolton para diagnosticar discrepancias de tamaño dentario mediante el análisis de la relación mesiodistal entre el tamaño de los dientes superiores e inferiores se encarga justamente de detectar este tipo de problemas, por tal motivo ha sido ampliamente utilizado en los estudios científicos y en la práctica cotidiana de la mayoría de los especialistas a nivel mundial.
Dado el interés de utilizar este valioso método en la práctica diaria y teniendo en cuenta que sus valores fueron obtenidos en modelos de individuos con características étnicas y raciales propias de otra población, en este estudio se propone determinar su aplicabilidad en nuestra localidad a través de la obtención de la proporción tanto total como anterior de una muestra peruana con características de oclusión normal natural, sin previo tratamiento ortodóntico. A su vez, determinar si existe alguna diferencia entre los géneros de dicha muestra.Tesis

Previous issue date: 2010-03-25The Bolton anterior ratio should be considered in the orthodontic planning in order to excellent occlusion achievement. The aim of this study was to verify wether some factors could be related to Bolton s anterior ratio: upper incisors buccolingual thickness, upper incisors mesiodistal tipping, overjet and overbite, and if there is sexual dimorfism. Thirty-five pairs of dental casts with natural normal occlusion had been evaluated, proceeding from 27 females and 8 male Caucasoid individuals, aged between 13 years old and 17 years and 4 months (mean age: 15 years and 8 months). A digital caliper and a piece of ruler were used for attainment of the measures. The anterior ratio was 77,48% (SD±2,22), showing to be statistically similar to Bolton s, 77,20%, SD±1,65. Based on Pearson s test, just the overbite showed to be related to the anterior ratio. It was not found sexual dimorfism.(AU)
A proporção anterior do tamanho dental de Bolton deve ser considerada no planejamento do caso quando se almeja uma oclusão ótima na finalização do tratamento ortodôntico. Este estudo teve por objetivo verificar se há relação entre as seguintes variáveis e a proporção anterior de Bolton: espessura vestíbulo-lingual dos incisivos superiores, relação entre a angulação dental dos incisivos superiores e o espaço mesiodistal por eles ocupado, sobressaliência e sobremordida, e se há dimorfismo sexual. Foram avaliados 35 pares de modelos em gesso com oclusão normal natural, provenientes de 27 indivíduos do sexo feminino e 8 do masculino, leucodermas, com idade entre 13 anos e 17 anos e 4 meses (idade média: 15 anos e 8 meses). Utilizou-se um paquímetro digital e um fragmento de régua para a obtenção das medidas. A proporção anterior encontrada foi de 77,48% (DP±2,22), estatisticamente semelhante ao valor proposto por Bolton, 77,20% (DP±1,65). De acordo com o teste de Pearson, somente a sobremordida mostrou relação estatisticamente significante com a proporção dental anterior. Não foi observado dimorfismo sexual.(AU)

Анотація:
The popular perception of the years 1945 to 1960 is that they constituted a transitional period from austerity to affluence. Material gains in the post-war years gradually increased, enhanced by full-employment, the establishment of the welfare state and a growing quantity of consumer goods. At first glance, it seems that working-class people's nonmaterial life, too, greatly changed. 'Traditional' leisure such as cinema-, pub- and football-going declined, replaced by more consumption-oriented, home- and family-centred leisure, such as television watching, do-it-yourself and pleasure motoring. Critics have seen this was symptomatic of the erosion of 'traditional' working-class-life styles, underlined by more communal and solidaristic social relationships. A close examination of post-war leisure in two workingclass towns questions the above dichotomy, and shows the significant continuity and diversity of people's leisure patterns. These were often deeply divided according to gender, age, life-stage and locality. Despite the rapidly changing trends of commercial leisure, and the increased intervention of the public sector in social life, the selfdetermined nature of working-class leisure does not seem to have been eroded. On the contrary, the general affluence of post-war Britain seems to have contributed in a modest way to increased leisure opportunities in which people could express their personal and social identity with less hesitation than before.

El uso actual en diversos países de programas de computadoras en Ortodoncia y la introducción de los modelos de estudio digitalizados han cambiado la forma tradicional de realizar las mediciones de los mismos, además de eliminar las desventajas que representa el método de medición manual. El empleo de un nuevo método de medición permitiría el desarrollo de un software como una herramienta auxiliar para la obtención de forma automática de un gran número de medidas para los índices ortodónticos tanto en dentición mixta como permanente; a partir de una correcta digitalización y calibrado previo sobre la imagen digitalizada para asegurar la exactitud de la medición.
Este estudio pretende comparar un nuevo método de medición digital en 2 dimensiones (2D) mediante el empleo de un Software desarrollado por el investigador para su uso en el análisis de Bolton, y utilizado como un recurso que nos permita hacer más fácil la medición en los modelos de estudio. Se realizó en una población constituida por 104 modelos de estudio de escolares entre 12 – 18 años de edad de la IE 139 GAM SJL. De un total de 120 modelos según los criterios de inclusión y exclusión; con un diseño descriptivo, comparativo y transversal, con el objetivo de identificar diferencias en la medición de los diámetros mesiodistales y la discrepancia obtenida del análisis de Bolton utilizando el método de medición digital y el método de medición manual.
El instrumento utilizado para las mediciones manuales fue un vernier digital centesimal con 0.02 de precisión y para las mediciones digitales fue previa digitalización y calibración de los modelos de estudio, marcando para diente sus puntos de contacto mesial y distal; los datos estadísticos fueron evaluados con el software SPSS versión 15, buscando promedios y desviación estándar y el uso de del “t” de Student para grupos pareados determinando la significancia.
Los resultados del estudio muestran que al comparar los promedios de los diámetros mesiodistales según el método de medición manual y digital se diferencian entre -0.17054808mm (1ºPMSD) y 0.14061923mm (ICSD).-- The current use in several countries in Orthodontics computer programs and the introduction of digital study models have changed the traditional way of performing measurements on them, while eliminating the disadvantages of the method of manual measurement. Using a new method of measurement would allow the development of software as an auxiliary tool for automatically obtaining a large number of measures for orthodontic indices both in the mixed dentition and permanent, from scanning and calibrated correctly prior on the scanned image to ensure the accuracy of the measurement. This study aims to compare a new digital measurement method in two dimensions (2D) by using a software developed by the researcher for use in the analysis of Bolton, and used as a resource that allows us to make it easier to measure in study models.

Campylobacter has been known for more than a century and today Campylobacter infection is considered the leading cause of bacterial foodborne disease in the developed world. Consumption of undercooked poultry and/ or handling of raw poultry are seen as the main transmissions of Campylobacterto humans due to high levels (107 and 108 CFUlg) of C.jejunifound in the intestinal tract of raw poultry. Several studies have suggested that by delaying addition of antibiotics for 2 h at 37??C there was a better recovery of Campylobacter in food samples. Rinses from sixty whole carcasses were treated to non-pre-enrichment incubation and preenrichment at 37??C or 42??C for 2, 4 and 6h. Using TECRA?????? CAMVIA immunoassay method, results showed that 100% of the carcasses were positive for Campylobacter when the pre-enrichment techniques was applied compared to just 30-60% positive results from non pre-enrichment techniques. To develop more efficient enrichment methods, thirty carcass rinses were incubated in Bolton, Preston and TECRA??? broth under aerobic and microaerobic atmosphere at 25??C and 42??C. Results' from TECRA??? CAMVIA revealed that recovery of Campylobacter spp. from TECRA??? broth under aerobic conditions and Bolton or Preston broth under microaerobic conditions are not significantly different (p > 0.05). Charcoal based CCDA and Karmali agar were as effective as blood based Campy-Cefex agar in isolating Campylobacter spp. although Karmali was better in suppressing the growth of background microflora. Twenty samples of retail poultry carcasses, offal, portion chicken, mince respectively and ten samples of each fresh chicken sausages and frozen nuggets respectively were enriched in TECRA??? and Preston broths for recovery of Campylobacter. TECRA??? CAMVIA showed that 100% (TECRA??? and Preston) of the portion chicken was Campylobacter positive compared to 80 (TECRA???)-100% (Preston) of liver, 90 (TECRA???)-1 00% (Preston) of minced chicken and 65 (TECRA???)-75% (Preston) of carcasses. The difference between the two broths to recover Campylobacter spp. was not significant.

The game of rugby union has evolved over the years into a professional sport in which an increased incidence of injury is evident. This also applies to the shoulder joint. It appears that certain risk factors are associated with shoulder pathology among rugby players as well as among the general population. In a competitive sporting environment where high stress loads are placed upon the body and joints, this association may be even more pronounced. Despite the fact that numerous studies have investigated the various factors that potentially play a role in the occurrence of shoulder injuries among sports participants generally, similar studies involving rugby union players in particular are limited. Previous studies have investigated and profiled rugby players with regards to posture, shoulder isokinetic muscle strength and electromyographic patterns, but no study has yet investigated the relationship between these factors and the role they may play in the risk of being injured. It would be beneficial to have a better understanding of the interplay between these factors and to identify the most likely factors to predict and/or prevent shoulder injuries in rugby players. With this information at hand, it might be possible to identify players who are at risk of shoulder injuries in order that they may potentially benefit from effective “pre-habilitation” protocols.
The aim of this study was to determine what the relationship between thoracic posture, isokinetic shoulder strength and scapulae muscle activation patterns in injured and uninjured rugby players was, and to determine which of these variables might predict shoulder injuries. Methods
Ninety-one (91) uninjured semi-professional rugby union players’ shoulder joint range of motion differences (ROM) were manually tested with the hand-behind-the-neck and hand- behind-the-back method. The profiling and classification of the thoracic posture was performed using the New York Posture Test. Scapular muscle activation patterns were determined by means of electromyography (EMG) measuring the activation of the upper and lower trapezius, serratus anterior and infrapinatus muscles. The isokinetic muscle strength of the rotator cuff muscles was determined at 60°/sec (Kin-Com 500H) measuring concentric and eccentric forces during internal and external rotation.
Results
Some participants presented with non-ideal or unsatisfactory shoulder internal rotators (59%) and external rotators (85%) bilateral ROM differences. Of all the participants, 68% presented with an abnormal shoulder position in the lateral view, and the sequence of muscle activation of the scapula stabiliser muscles was found to be: serratus anterior; lower trapezius; infraspinatus and then upper trapezius. The isokinetic antagonist/agonist strength ratio for shoulder rotation during concentric muscle contraction was 64% for the non-dominant and 54% for the dominant shoulder. The corresponding ratios for the eccentric muscle contraction of the non-dominant and dominant shoulders were 67% and 61% respectively.
The median muscle onset times of the backline players’ non-dominant infraspinatus muscles were 35.90 ms for ideal, 95.20 ms for non-ideal, and 93.90 ms for the unsatisfactory external rotators’ range of motion (ROM) differences. The median firing orders of the forwards’ dominant lower trapezius muscle was 3 for ideal, 1 for non-ideal, and 2 for unsatisfactory external rotators’ ROM differences. Among the forward shoulder group and the normal shoulder position group of the forwards respectively, the median muscle onset time of their non-dominant infraspinatus muscle was 113 milliseconds (ms) and 42 ms. Their non- dominant serratus anterior muscles’ median onset time was 78.85 ms among the players with a rounded back, and 31.90 ms among the players with a normal thoracic curvature. The backline players displayed a median non-dominant serratus anterior onset time of 47.45 ms (in the uneven shoulder group) versus 32.75 ms (in the even shoulder group). The median firing order of the backline players’ non-dominant infraspinatus muscle was third in the normally curved back group. Among the players with an abnormally rounded back, however, the median firing order changed to second. The median external rotation/internal rotation isokinetic strength ratio of the forward players was 63% (forward shoulders), versus 56.50% (normal shoulder position). This was for their non-dominant shoulders. Certain isokinetic shoulder strength ratios displayed statistically significant correlations with scapular muscle activation patterns but they were not clinically significant.
Players who had sustained shoulder injuries during the season differed significantly from those who had not sustained injuries with regards to the following baseline measurements: age (the injured were older), height (the injured were taller) and non-dominant/dominant concentric external rotation ratio (the injured had a higher ratio). Among the backline players baseline differences occurred within age (the injured were older), weight (the injured were heavier), height (the injured were taller) and the body mass index (BMI) (the injured had a higher BMI). The variables that displayed statistically significant predictive values towards future injury were age (1.34 times increase for each year older), insufficient shoulder external rotator ROM differences (16.15 times increase if an unsatisfactory ROM difference occurs), uneven shoulders (4.43 times increase if shoulders were abnormally uneven) and the non- dominant/dominant concentric external rotation strength ratio (a 1.42 times increase for every
10% that the ratio increases).
Conclusion
Profiling of the group of players revealed that their non-ideal or unsatisfactory flexibility of shoulder external rotators, their forward shoulders in the lateral view, and their weakness of the shoulder external rotators did not result in abnormal scapular muscle activation patterns.
Positive relationships were found between certain postural abnormalities (forward shoulders, a rounded back and uneven shoulders) and the delay of muscle onset times of infraspinatus and serratus anterior, as well as the firing order of infraspinatus. Forward shoulders increased antagonist/agonist isokinetic shoulder rotation strength ratios. Non-ideal or unsatisfactory flexibility of shoulder external rotators displayed positive relationships with altered infraspinatus muscle onset times and an altered lower trapezius muscle firing order. No clinically significant correlations were found between isokinetic shoulder strength ratios and scapulae muscle activation patterns.
It appears that posture (uneven shoulders), has a higher predictive ability than shoulder strength imbalance (non-dominant/dominant concentric external rotation ratio) regarding future shoulder injury. However, age and especially external rotator ROM deficiency proved to be strong predictors of future shoulder injury in semi-professional rugby players.Thesis (PhD (Human Movement Science))--North-West University, Potchefstroom Campus, 2013.

El objetivo de la Tesis Doctoral era introducir y comparar un nuevo Método Digital que basándose en la digitalización de los modelos de estudio de escayola y un software de apoyo permitía calcular la medición de los tamaños mesiodistales de los dientes, longitudes de arcada, discrepancias osedodentarias e índices de Bolton, además de predecir los tamaños de los dientes no erupcionados en dentición mixta.Se seleccionaron 100 pares de modelos de estudio en dentición permanente, 30 correspondían a mujeres y 70 a hombres, con una edad decimal media de 14,8 años (rango 11,2-22,7 años).Procedimos a la medición de los tamaños mesiodistales de todos los dientes de cada uno de los pacientes, por los dos métodos de medición seleccionados.En el Método Tradicional, medimos los tamaños con un calibre tradicional de una sensibilidad de décimas de milímetro, directamente sobre los modelos de escayola, mientras que en el Método Digital, se digitalizaron todos los modelos de estudio con un escáner convencional, para pasar a realizar las mediciones directamente sobre la imagen con el ratón del ordenador como interfase y una sensibilidad de centésimas de milímetros. Posteriormente, con unas tablas seleccionadas y ordenadas por percentiles, se tomaron diferentes dientes (incisivos y molares) como dientes de referencia para determinar el resto de los tamaños mesiodistales de los dientes no erupcionados (caninos y premolares). Los coeficientes de correlación lineal para todos los valores entre el método digital y tradicional fueron cercanos al 1, con ordenadas en el origen de 0 y pendientes de 1, significando con ello, que los datos entre ambos métodos eran idénticos.Para la predicción de los tamaños dentarios, se utilizaron coeficientes de correlación lineal obteniendo muy buenos resultados siendo la combinación del incisivo superior y del molar inferior junta a las listas seleccionadas la mejor combinación para esta predicción.Según una encuesta realizada entre Ortodoncistas españoles y estadounidenses la medición de todos los parámetros anteriores por el método tradicional resultaba laboriosa de realizar y calcular, lo que provocaba su omisión en más de la mitad de los casos. Igualmente, se nos planteaba un problema en casos de Dentición Mixta en los cuales no podíamos realizar una medición directa de los dientes no erupcionados. Por ello, un método digital parecía la opción más adecuada, sencilla, exacta y rápida para el profesional.En ocasiones, nos encontrábamos con modelos de estudio con dientes poco erupcionados donde era difícil localizar los puntos de contacto, siendo la imagen obtenida de poca calidad y exactitud.Como conclusión de nuestro estudio podemos afirmar que el Método Digital propuesto, era igualmente sensible y exacto que el Método tradicional para la medición de los tamaños mesiodistales de los dientes y para el cálculo de los índices de Bolton, además de para predecir los tamaños en dentición mixta de manera exacta.El método digital era además más rápido que el tradicional con las ventajas de magnificar la imagen de los dientes para su mejor visualización y la posibilidad de almacenar las imágenes en formato digital evitando los problemas del almacenamiento físico de los modelos de escayola.The aims of the Doctoral Thesis were; to introduce and compare a new, fast and accurate Digital Method to measure mesio-distal tooth size, arch length, discrepancy and Bolton index and to predict mesio-distal tooth size for unerupted teeth in mixed dentition. One hundred dental casts of patients were selected, the sample comprised 30 females and 70 males, with a mean decimal age of 14.8 years (range 11.2 -22.7 years). The mesiodistal sizes of the upper and lower teeth of each cast were measured by both methods as follows:For the Traditional Method special callipers were used to measure the mesiodistal size of the casts. For the Digital Method the casts were scanned and with the aid of the mouse as a user interface, we marked the points of the mesiodistal size of each permanent tooth on the image of the casts. The software designed for this purpose, determines dental sizes in millimeters automatically. From this data, we were able to predict the rest of unerupted tooth sizes.Correlation coefficients were almost 1, which shows that values of both Methods were the same. We prepared linear regression graphics in which we represented and compared "real values" and "predicted ones" for each tooth type for every reference tooth. Our results showed the upper central incisor and lower first molar combination was the best reference teeth.The Digital Method presented in this Thesis made it possible to determine measurements and calculations quickly and accurately once the casts have been digitised.The conclusions of our Thesis were that the Digital Method was as sensible and accurate than the Traditional one for measuring mesiodistal tooth-size, Bolton index and to predicting mesiodistal tooth-size of the unerupted teeth.

In 1990 a small self-published journal/magazine called The Watcher was distributed among New Zealand's occult underground. The Watcher described itself as 'the New Zealand Voice of the Left Hand Path', and was published as the journal of the Order of the Left Hand Path. The Watcher and the Order directed its attentions towards those occultists who identified themselves as Satanists and, as such, the journal articulated a distinctly Satanic philosophy and perspective. However, as the journal evolved and developed, renaming itself as The Heretic and The Nexus in later years, there arose alongside Satanic philosophy an increasing emphases on what could be called esoteric Nazism or esoteric Nationalism. Given that the editor of The Watcher was Kerry Bolton, a man who has been immersed in New Zealand's Nationalist/neo-Nazi movement since the early 1970s, such an increasingly political orientation was perhaps unsurprising. This thesis examines the way in which the Order bought Satanic and neo-Nazi ideologies together and the resulting synthesis. It also looks at the transition from being a Satanic order led by a neo-Nazi to an openly neo-Nazi Order that uses Satanic philosophy to justify and popularise its conception of National Socialism.

Syftet med detta examensarbete var att undersöka användandet av drama som pedagogiskt verktyg i gymnasieskolans undervisning och elevers attityder till det. För att ta reda på detta användes en enkätundersökning bestående av kvalitativa och kvantitativa frågor på en gymnasieskola i Mellansverige. Resultatet från undersökningen visar att drama som pedagogiskt verktyg upplevs ha flera olika effekter för eleverna, både pedagogiskt som individuellt. Slutsatsen är således att drama inte bara är ett verktyg förbehållet läraren för att skapa en lustfylld undervisning utan drama är också ett betydelsefullt redskap som elever kan använda för sin sociala och emotionella utveckling.

Previous issue date: 2013-03-22The calculation of tooth mass discrepancy, essential for good planning and a proper orthodontic finishing, when performed manually, besides being laborious, requires considerable time consumption. The aim of this study was to develop and test Bolton Freeware, a software for analysis of the tooth mass discrepancy of Bolton, aiming to minimize the consumption of time in a less onerous way. The digital analysis of the software was done by means of two-dimensional scanning of plaster study models and compared to manual evaluation (gold standard), using 75 pairs of stone plaster study models divided into two groups according to the magnitude of the Curve of Spee (group I from 0 to 2 mm, group II greater than 2 to 3mm). All the models had permanent dentition and were in perfect condition. The manual evaluation was performed with a digital caliper and a calculator, and the time required to perform the analysis for both methods was recorded and compared. In addition, the software was evaluated by orthodontists regarding its use, by means of questionnaires developed specifically for this purpose. Calibration was performed prior to manual analysis, and excellent levels of inter-rater agreement were achieved, with ICC > 0.75 and r > 0.9 for total and anterior proportion. It was observed in the evaluation of error of the digital method that some teeth showed a significant systematic error, being the highest measured at 0.08 mm. The analysis of total tooth mass discrepancy performed by Bolton Freeware, for those cases in which the curve of Spee is mild and moderate, differ from manual analysis, on average, 0.09 mm and 0.07 mm respectively, for each tooth evaluated, with r> 0, 8 for total and anterior proportion. According to the specificity and sensitivity test, Bolton Freeware has an improved ability to detect true negatives, i.e. the presence of discrepancy. The Bolton analysis digitally performed was faster, with an average difference of time consumed to perform the analysis of Bolton between the two methods of approximately 6 minutes. Most experts interviewed (93%) approved the usability of the software

O objetivo desse estudo foi o desenvolvimento e teste do Bolton Freeware, um programa de computador para an?lise de discrep?ncia de massa dent?ria de Bolton, visando minimizar o consumo de tempo de forma menos onerosa. A an?lise digital no software foi feita por meio da digitaliza??o bidimensional de modelos de estudos de gesso e comparada com a avalia??o manual (padr?o-ouro), utilizando 75 pares de modelos de estudo em gesso pedra, divididos em dois grupos conforme a magnitude da curva de Spee (0 a 2mm e de 2 a 3mm). Todos os modelos possuiam dentadura permanente e se encontravam em perfeito estado de conserva??o. A avalia??o manual foi realizada com paqu?metro digital e calculadora e o tempo requerido para realiza??o da an?lise nos dois m?todos foi cronometrado e comparado. Al?m disso o programa foi avaliado por 30 ortodontistas quanto ao seu uso, por meio de question?rios desenvolvidos especialmente para essa finalidade. Foi realizada calibra??o pr?via para an?lise manual e se obtiveram ?timos n?veis de concord?ncia interexaminador, com CCI>0,75 e r>0,9 para a discrep?ncia total e anterior. Observou-se, na avalia??o do erro do m?todo digital, que alguns dentes apresentaram um erro sistem?tico significante, sendo o maior quantificado em 0,08mm. A an?lise da discrep?ncia de massa dent?ria total realizada pelo Bolton Freeware, para aquele casos de curva de Spee leve e moderada, diferiu da an?lise manual, em m?dia, de 0,09mm e 0,07mm respectivamente, para cada dente avaliado, com r>0,8 para propor??o total e anterior. De acordo com os testes de especificidade e sensibilidade, o Bolton Freeware possui uma melhor capacidade de detectar os verdadeiros negativos, ou seja, a presen?a da discrep?ncia. A an?lise de Bolton realizada digitalmente foi mais r?pida, com a m?dia das diferen?as dos tempos consumidos para realiza??o da an?lise de Bolton entre os dois m?todos de aproximadamente 6 minutos. A maioria dos especialistas entrevistados (93%) aprovou a usabilidade do programa

Previous issue date: 2010-10-06Introduction: The Bolton analysis, analysis that quantifies the tooth size is an important reference for professionals seeking appropriate orthodontic finishing. Objective: The objective of this study is to verify that there is discrepancy between the subjects with normal occlusion and malocclusion Class I and Class II division 1 belonging to the selected sample, compared to the values reported by Bolton and also check difference related to sexual dimorphism. Methods: 3 groups of 35 pairs of plaster casts each, separated by the type of occlusion, pertaining to the program of graduate orthodontics at the Methodist University of Sao Paulo were measured with a digital caliper at its greatest distance mesiodistal since 1st right molar to 1st molar left, the upper and lower arches, with permanent teeth. The values were tabulated and the proportion of Bolton has been applied. Results: Respectively for groups 1, 2 and 3, the total ratio found was 90.36 (SD ± 1.70), 91.17 (SD ± 2.58) and 90.76 (SD ± 2.45) and the anterior ratio was 77.73 (SD ± 2.39), 78.01 (SD ± 2.66) and 77.30 (SD ± 2.65). Conclusion: there was no sexual dimorphism or statistically significant difference compared to the values suggested by Bolton.
Introdução: A análise de Bolton, análise que quantifica o tamanho dentário, é uma referência importante para profissionais que buscam finalizações ortodônticas adequadas. Objetivo: O objetivo deste trabalho é verificar se há discrepância entre os indivíduos com oclusão normal natural e maloclusões de Classe I e de Classe II divisão 1 de Angle pertencentes a amostra selecionada, em relação aos valores encontrados por Bolton, bem como verificar também se há dimorfismo sexual. Metodologia: 3 grupos contendo 35 pares e modelos em gesso cada, separados pelo tipo de oclusão, pertencentes ao acervo do programa de pós-graduação em Ortodontia da Universidade Metodista de São Paulo foram medidos com paquímetro digital em sua maior distância mésiodistal desde 1º molar direito a 1º molar esquerdo, dos arcos superiores e inferiores, com dentição permanente. Os valores foram tabulados e a proporção de Bolton foi aplicada. Resultados: Respectivamente para os grupos 1, 2 e 3, a proporção total encontrada foi de 90,36 (DP±1,70), 91,17 (DP±2,58) e 90,76 (DP±2,45), e a proporção anterior foi de 77,73 (DP±2,39), 78,01 (DP±2,66) e 77,30 (DP±2,65). Conclusão: não houve dimorfismo sexual nem diferença estatisticamente significante comparando os valores aos sugeridos por Bolton.

Observou-se que não ocorreu dimorfismo sexual entre as discrepâncias de tamanho dentário e os diferentes tipos de oclusão dentária; as proporções estabelecidas por Bolton não se aplicaram ao grupo com Oclusão Normal; na Oclusão Normal, Classe I, Classe II e Classe III, houve um predomínio de excesso dentário total (RAZ12) no arco inferior; na Classe I houve uma igualdade na distribuição de excesso dentário anterior (RAZ6) nos arcos superior e inferior; na Oclusão Normal, Classe II e Classe III, ocorreu um predomínio de excesso dentário anterior (RAZ6) no arco inferior, em relação ao arco superior; os excessos dentários não contribuíram na ocorrência das más oclusões e; as discrepâncias total e anterior (RAZ12 e RAZ6) não interferiram diretamente nas larguras e comprimentos dos arcos, bem como no posicionamento dos dentes anteriores.
The general purpose of this study was to evaluate tooth size discrepancy in normal occlusion and in different malocclusion types and its relationship to measurements which determine arch form and anterior tooth positioning. One hundred and eighty five sets of casts of leucoderms were divided into four groups: Group 1 (consisted of 41 pairs of models with Normal Occlusion, 20 males and 21 females); Group 2 (consisted of 44 pairs of models with Class I malocclusion, 22 males and 22 females); Group 3 (consisted of 54 pairs of models with Class II, div. 1, malocclusion, 28 males and 26 females) and Group 4 (consisted of 46 pairs of models with Class III malocclusion, 23 males and 23 females). No sexual dimorphism was observed between tooth size discrepancies and different types of dental occlusion; the proportions stated by Bolton were not applied to the Normal Occlusion group; in Normal Occlusion, Class I, Class II and Class III there was an overall ratio excess in the lower arch; in Class I there was an equal anterior excess distribution in upper and lower arches; in Normal Occlusion, Class II and Class III there was a prevalent incidence of anterior ratio excess in lower arch; upper arch excess did not contribute to malocclusion occurrence and overall and anterior discrepancies did not interfere with arch width and length, as well as with anterior tooth positioning.

No sexual dimorphism was observed between tooth size discrepancies and different types of dental occlusion; the proportions stated by Bolton were not applied to the Normal Occlusion group; in Normal Occlusion, Class I, Class II and Class III there was an overall ratio excess in the lower arch; in Class I there was an equal anterior excess distribution in upper and lower arches; in Normal Occlusion, Class II and Class III there was a prevalent incidence of anterior ratio excess in lower arch; upper arch excess did not contribute to malocclusion occurrence and overall and anterior discrepancies did not interfere with arch width and length, as well as with anterior tooth positioning.

This thesis presents the results of testing to determine if spacing between bolts in a multiple-bolt, single-shear connection subjected to natural hazard loading affects seven strength and serviceability parameters: maximum load, failure load, E.E.P. yield load, 5% offset load, elastic stiffness, E.E.P. energy, and ductility ratio. This research also determines if a statistical difference exists between previously published research for 4D spacing as compared to results produced by this research for five alternate spacings: 8D, 7D, 6D, 5D, and 3D. Finally, this research determines which of the spacings examined: 8D, 7D, 6D, 5D, 3D; produced the most optimal results for each examined strength and serviceability parameter where optimization is based on economy and performance.
Three connection configurations with five different spacings between bolts were subjected to reverse cyclic loading for a total of one hundred and fifty tests. The reverse cyclic protocol was based on recommendations by the Consortium of Universities for Research in Earthquake Engineering (CUREE) for testing woodframe structures. The same connection configurations were also subjected to monotonic loading for an additional forty-five tests.
Results of this research can be used to evaluate the current design recommendation presented in the National Design Specification (NDS) for Wood Construction (AF&PA, 2001) of spacing bolts at four times the bolt diameter (4D) to determine if a different spacing should be recommended for natural hazard loading conditions.

The Fully Encapsulated Resin Bolt (FERB) is widely utilised for strata control and ground support in civil and mining applications worldwide, with approximately 6 million installed per annum by the Australian coal mining industry. Independent studies have concluded that 30-35% of these rockbolts, which represents an annual expenditure of $40 million, are ineffective. The anchorage and failure mechanisms of FERB are yet to be quantified, and support systems are designed primarily from empirical rather than scientific methods. There are no standardised methods of assessing FERB components, installation techniques and support behaviour. The majority of research into FERB support systems remains commercial intellectual property, with little information released into the public domain. This thesis investigated several variables of FERB support systems, and also examined differences between field and laboratory pull-out test load distributions. This research was conducted in two phases, with Phase 1 seeking standardised methodology and repeatability in results, while Phase 2 further refined Phase 1 methods and extended the range of tests. The results in both phases were encouraging, with reasonable repeatability attained in all testing series. The findings included: ??? Annulus Thickness: There was little change in load capacity with small annulus thickness, however the maximum peak load (MPL) significantly reduced once annulus thickness exceeded 4mm ??? Resin Installation Spin Time: Underspinning of cartridge resin was found to have an insignificant effect on rockbolt load/deformation characteristics. Overspinning, however, led to a dramatic reduction in anchorage performance with a lessening in both MPL and stiffness ??? Rockbolt Load Transfer: The magnitude of an applied load reduced to zero along the length of the rockbolt, being greatest nearest the rock free surface (the point of load application). An exponential reduction was found when tested in the manner of laboratory tests, with the loading jack reacting against the free surface. This reduction was linear when the load was applied as in the field, with no load placed on the free surface This basic investigation into FERB support systems has validated many empirical understandings of rockbolts, while highlighting the need for further testing into several key areas.

This thesis presents the results of testing to determine the significance of the group action factor at the 5% offset yield and capacity of single-shear bolted wood connections loaded parallel to grain. The single and multiple-bolt connections tested represent common connection geometries used in wood construction in the United States. The results of both monotonic and cyclic loading of connections are presented.
Monotonic test data was used to determine an appropriately scaled CUREE Displacement Controlled Quasi-Static Cyclic Protocol. Overall, one hundred and eighty connections were tested using this cyclic protocol based on data obtained from thirty-three monotonic tests.
Tested assemblies had geometric variables that include number of bolts per row, number of rows, bolt diameter, and side member material. In addition, the main and side member material and thickness were designed to produce three of the four major connection yield modes as defined by the 1997 National Design Specification for Wood Construction (AF&PA, 1997).
Results from this research address the need for adequate spacing of bolts in a row to control the brittle connection behavior that directly affected the group action factor at capacity.Master of Science

An analytical and experimental investigation was conducted to study the six bolt flush moment end-plate connection configuration which is used in steel frame construction. The limit states of plate yielding and bolt fracture were analyzed using yield-line theory to predict endplate thicknesses and a split-tee analogy to develop a method to predict bolt forces. Five experimental tests were conducted on four configurations within a matrix of geometric parameters. The predicted ultimate moment showed good . correlation to the yield moment obtained from the experimental deflection plots. The experimental bolt forces correlated well with the predicted bolt forces when plotted versus the applied moment. Additionally, an equation to model the moment-rotation relationship was developed from a regression analysis to determine the construction type suitable for a given connection configuration. Finally, a method of designing the six-bolt flush end-plate configuration is presented and an example given.Master of Science

Double-nut anchor bolt systems are used in the erection of traffic signal poles, high-mast luminaries, and other highway appurtenances. An absence of a tightening standard for such systems decreases the confidence in their performance under fatigue loading. Past research has shown that a tightening standard should include the development of preload in the anchor bolt sufficient to provide adequate resistance to fatigue failure. Preload should be measured by a turn-of-the-nut method.
Laboratory progressive tightening tests were performed in order to monitor the stress ranges occurring in the bolt at various locations of interest at various degrees of turn-of-the-nut tightness. Tests were performed on six diameters of anchor bolt ranging from 1 to 2-1/4 inches in diameter and two different categories of thread pitch: UNC and 8UN. Plots of stress range versus degree of tightness were developed for each test and evaluated to find the minimum degree of turn-of-the-nut at which stress range inside the nuts dropped below that outside the nuts. This shift was considered to be the principle theoretical indication of adequate performance. A fatigue test which saw failure outside the double-nut connection was set down as the practical indicator of adequate fatigue performance.
The 2 inch 8UN bolt was chosen as the critical specimen due to its overall low generation of preload during tightening tests. Theoretical testing showed that 1/24 turn-of-the-nut would guarantee sufficient fatigue performance. Two practical fatigue tests of the bolt at that tightness saw one positive and one negative failure.
After actual lab tests, finite element modeling was used to investigate the behavior of the bolt. It was found that performance did not see improvement until 1/12 turn-of-the-nut.
After all results were considered, a standard of 1/6 turn-of-the-nut or refusal of tightening by specified methods was recommended, provided a minimum of 1/12 turn-of-the-nut was achieved. This value allows for ease of measurement, sufficient tightness, degree of safety, and has been shown in past testing not to cause failure through over-tightening. However, tightening to only 1/12 turn-of-the-nut still provided adequate performance.
