In recent years, a prolific amount of books and articles on Paul have sought to bring Paul's life and theology into new light. This dissertation is an investigation into an aspect of Paul's life and thought which has remained little discussed in secondary literature, even when as of late, the social world of Paul has been in more focus — that of Paul's portrayal of manual work, and Ins use of the imagery of the workplace (ideas of toil, labour, weakness, slavery, economics, and so on). The thesis contributes to our understanding of what may have affected the portrayal of work in Paul's thought by surveying all the available evidence, and secondly, it concludes by way of providing a balance to the studies of Hock and others, that Paul's portrayal of work was derived from his Jewish heritage as well as his Graeco-Roman context. The first chapter introduces the subject, surveys previous research to demonstrate the need for the present study, and sets out the broader context of the literature to be examined. Chapter two considers the Jewish evidence. Two ways of looking at work are identified. Firstly, the portrayal of God as worker is examined and secondly, the portrayal of human work is discussed. These themes shape chapter three which discusses the Graeco-Roman evidence, and Chapter four which examines the non-Pauline Christian material. Chapter five considers the portrayal of work in the Pauline letters, cross-referencing with the previous chapters where relevant. The final chapter summarises the conclusions that are drawn from the evidence and outlines their implications for current scholarship in Paul.

Although much effort has been placed into the reduction of risks associated with manual materials handling, risk of musculoskeletal disorder development remains high. This may be due to the additional muscle activity necessary for the maintenance of postural equilibrium during work tasks. This research proposes that postural control and subsequent additional muscle activity is influenced by the magnitude of the external load and the degree of body movement. The objective of this research was to identify whether performing tasks with increased external load and with a greater degree of trunk motion places additional strain on the musculoskeletal system in excess of that imposed by task demands. Twenty-four male and twenty-four female subjects performed four load manipulation tasks under three loading conditions (0.8kg, 1.6kg, and 4kg). Each task comprised of a static and dynamic condition. For the static condition, subjects maintained a stipulated posture for ten seconds. The dynamic condition required subjects to move and replace a box once every three seconds, such that a complete lift and lower cycle was performed in six seconds. Throughout task completion, muscle activity of six pairs of trunk muscles were analysed using surface electromyography. This was accompanied by data regarding ground reaction forces obtained through the use of a force platform. After the completion of each condition subjects were required to identify and rate body discomfort. Differential analysis was used to isolate the muscle activity and ground reaction forces attributed to increased external load and increased trunk movement. It was found that the heaviest loading conditions (4kg) resulted in significantly greater (p<0.05) muscle activation in the majority of muscles during all tasks investigated. The trend of muscle activity attributed to load was similar in all significantly altered muscles and activation was greatest in the heaviest loading condition. A degree of movement efficiency occurred in some muscles when manipulating loads of 0.8kg and 1.6kg. At greater loads, this did not occur suggesting that heavier loading conditions result in additional strain on the body in excess of that imposed by task demands. In manipulated data, trend of vertical ground reaction forces increased with increased load in all tasks. Sagittal movement of the centre of pressure attributed to load was significantly affected in manipulated data in the second movement phase of the “hip shoulder” task and the second movement phase of the “hip twist” task. The “hip reach” task was most affected by increased load magnitude as muscle activity attributed to load was significantly different (p<0.05) under increased loading conditions in both movement phases in all muscles. Further, a significant interactional effect (p<0.05) between condition and data point was found in all muscles with the exception of the right and left lumbar erector spinae during the second movement phase of the “hip reach” task. Muscle activity associated with increased trunk motion resulted in additional strain on the trunk muscles in the “hip shoulder” and “hip reach” tasks as muscle activity associated with the static component of each of the above tasks was greater than that of the dynamic tasks. Trend of ground reaction forces attributed to increased trunk motion generally increased under increased loading conditions. Additionally, a significant interactional effect (p<0.05) between load and muscle activity pattern was found in all muscles during all tasks, with the exception of the right rectus abdominis in the first movement phase of the “hip shoulder’ task, the left rectus abdominis in the second movement phase of the “hip knee” task and the right latissimus dorsi during the first movement phase of the “hip twist” task. This was accompanied by a significant interactional effect (p<0.05) between load and sagittal centre of pressure movement attributed to load, in both movement phases of all tasks investigated. From this research it can be proposed that guidelines may underestimate risk and subsequently under predict the strain in tasks performed with greater external loads as well as tasks which require a greater degree of trunk motion. Therefore, this study illustrates the importance of the consideration of the muscle activity necessary to maintain postural equilibrium in overall load analyses.

Manual lifting is dynamic in nature and involves asymmetrical loading of the human body. This study investigated kinematic and kinetic characteristics of asymmetrical lifting in three dimensions, and then constructed a 3-D biomechanical force model of the lower back which is capable of quantifying torsional stress on the human spine. Eleven healthy adult male manual workers were recruited as subjects and lifted a 1 Okg load placed at the sagittal plane (0°) and at 30°, 60° and 90° lateral planes to the right, from 150mm and 500mm initial lift heights, respectively, to an 800mm high bench in the sagittal plane. Subjects' spinal motions and the trajectorial movements of the load in three-dimensional space were monitored simultaneously by a Lumbar Motion Monitor and a V-scope Motion Analyzer. Generally, the spinal motion factors increased as a function of increasing task asymmetry and differed (p < 0.05) between the lower (150mm) and higher (500mm) levels in the sagittal plane. In all asymmetrical conditions the motion factors showed a dramatic increase at the 500mm level compared to the increase at the 150mm level. The rates of increase in the horizontal and frontal planes were greater than those in the sagittal plane. Task asymmetry had a significant effect on the spinal kinematic parameters in the frontal plane at the two lift heights, and only at the high level (500mm) in the horizontal plane, with exception of average acceleration . Initial lift height exerted a significant effect on peak velocity and acceleration in both frontal and horizontal planes and on range of motion in the horizontal plane. Kinetic characteristics of the object being lifted in three-dimensions increased with an increase in task asymmetry. The increase was more dramatic in the lateral direction in the horizontal plane. However, motion factors in the vertical direction dominated the full range of the lift, irrespective of task asymmetry and lift height. The kinetic measures differed (p < 0.05) between the lower ( 1 50mm) and the higher (500mm) levels in the vertical direction except for average force. Task asymmetry had a significant effect on dynamic measures in the anterior-posterior direction. Both task asymmetry and lift height had a significant effect on dynamic motion factors in the lateral direction. From insights gained in the empirical study a three-dimensional biomechanical force model of the lower back was constructed based on a mechanism of muscle force re-orientation in the lumbar region. Acknowledging that the lower back is designed to be able to rotate around its longitudinal axis, the proposed model accounts for compression and shear forces and a torsional moment. The model has similar predictability to Schultz and Andersson's (1981) model when the human trunk exerts only a flexion-extension moment in the sagittal plane, but additionally predicts dramatic increases in shear forces, oblique muscle forces and torsional moment under asymmetrical lifting conditions which the Schultz-Andersson model does not. The increase rates in these forces and moment are not linearly related over task asymmetric angle.

This research demonstrates the feasibility of modifying a Predetermined Time Standard (PTS) to model a specific worker precisely and efficiently. The Worker Profile uses the results of a half hour of testing to algebraically modify each of the work elements in the PTS. The modified system can then be used with any job that has been described in the PTS. Specific performance times can be estimated for the modeled individual on each of the described jobs. The traditional functional assessment techniques developed by medical, psychological and social care providers lack the quantitative precision of industrial engineering work descriptors. In addition to providing the rehabilitation engineer a usable assessment of the client's abilities the Worker Profile should aid in the sharing of information among the specialists on the rehabilitation team. Unlike previous efforts directed at modeling disabled workers' abilities, this study individually modifies the elements used to describe unique, specific jobs. The element by element Worker Profile approach encourages proper job selection and work station modification. The model produces a Worker Profile which can be used to predict the worker's performance on any job for which an appropriate job standard has been written. The Worker Profile Model offers the employer of assembly workers an opportunity to predict the performance of disabled workers on specific jobs without the expense and time required to train and test them on each available job. The model has several additional qualities including reduced assessment costs and extremely flexible application both in the performance of existing jobs and to the modification of jobs to optimize them to the disabled workers’ abilities. In addition to extending the Worker Profile Model this study examined the effect of practice on the work behaviors of disabled workers. Practice has been observed to affect differentially the speed and accuracy of work elements among able-bodied workers. The effects of practice were previously undocumented for disabled workers. Examination of work element performance changes as learning occurred not only identified the locus of improvement in job performance, but also, illustrated a qualitative difference in learning patterns when a tactical improvement in work method occurred. / Ph.

Despite extensive research into musculoskeletal disorders (MSDs) they continue to plague workers. Manual materials handling (MMH), in particular the concurrence of load manipulation and awkward body posture, has been identified as a key factor in the onset of MSDs. Only a few studies have looked at the interaction between manipulation tasks and working posture during assembly tasks and as a result their relationship has not been widely explored. Assessing the stresses resulting from individual task factors and body posture in isolation and adding them together may be too simplified to estimate an overall risk profile, since this does not take into account that there may be a non-linear interaction in strain responses when manipulation task and body posture interact. Therefore, the present study investigated biophysical, physiological and psychophysical responses to combined tasks, rather than individual tasks of body posture and manipulative tasks. The objective of the research was to establish the interactive effects of constrained body postures and manipulative tasks and to identify whether a cumulative or compensatory reaction occurs during this interaction. Nine conditions were assessed in a laboratory setting, which included combinations of three working postures (standing, sitting and stooping) and three assembly tasks (torque wrenching, precision and no task). Thirty-six subjects were required to complete all nine conditions, with each condition lasting ninety seconds. Muscle activity was recorded for seven muscles from the upper extremity, trunk and lower extremity regions and was complemented by physiological (heart rate, tidal volume, minute ventilation, oxygen consumption, energy expenditure and breathing frequency) and psychophysical (body discomfort) data. At the completion of all nine conditions subjects completed a retrospective psychophysical rating questionnaire pertaining to discomfort felt during the conditions. Responses obtained for the different task and posture combinations revealed compensatory reactions (additive > combined) for most of the conditions assessed for the biomechanical and physiological responses. In the majority of cases for muscle activity, no significant differences were found between the combined and the additive effects (p < 0.05), while for the physiological responses there were mostly significant differences observed. Psychophysical responses indicated that there was a significant difference overall between the additive and combined effects. The results of this study demonstrate that in order to identify risk areas, manipulation tasks and constrained working postures may be considered either in isolation and added together (additive) or as a combined task, since there were very few significant differences observed between these two effects. Further studies are required, however, to provide conclusive evidence.

The thesis analyses representations of body and class, and their wider ideological meaning, in Swedish power sports from 1920 to 1960. Boxing and weightlifting – sports dominated by manual workers – are chosen as study objects. The sources used are magazines connected to the power sports, and autobiographies by four prominent athletes. The thesis relates to different areas of previous research. One concerns the body as such, from a social and cultural history perspective, another revolves around medial and autobiographical representations in relation to sports, and a third is about the relationships between body, class and sport. In the analysis, the Bourdieusian concepts capital and hexis are added to a discussion on the ways that value is attached to the body, linked to the notions of use value and exchange value. The content analysis of the source material makes ground for an analysis of more implicit ideological aspects, e.g. using Barthes’s theory on mythology. Manual labour and working life appear as central organising themes in the source material. Boxing and weightlifting were largely regarded and designated as professions, challenging ideals of amateurism. A physically demanding manual work was depicted as natural breeding grounds where sports practitioners became skilled. This masculine ideal united people from various manual working groups (not only from the working class in its socio-economic sense) where the emphasis was put on the physical strength and ability of the athlete to work hard. The body was used in a form of class polemics, preferably against middle and upper class people. Certain aspects of strength and style of athletic performance were related to particular levels of intelligence and education. Power athletes from the manual working groups were depicted as “natural”, with associations to rural areas, not least working in the forest. The ideas of naturalness in its most derogatory sense of being close to animals and lacking civilisation, was however mostly used in connections with black athletes. Success stories were common narratives about power sports as arenas of success. They included a powerful norm that success must be cultivated, where the responsibility was put upon the athlete himself. Successful athletes from manual working groups could transform their physical capital into economic capital, which was often depicted as short-lived because of aging and individual shortcomings. A commercial consumer culture became more explicit in the 1950s, when bodybuilding had its Swedish breakthrough within weightlifting. Sports training was rationalised and largely decoupled from its associations with manual work. This led to an increased reification of the body as pure surface, which was attributed a value itself. The body became an area of consumption, a commodity with an exchange value, when decoupled from its use value as labour or tool for sporting success. As to the ideological aspects of the development, it is shown that there was a widespread individualist norm. Only the individual himself had the possibility to rise up and achieve success. The ideal of manual work was more of a moral and cultural nature, than political. Although there were some collectivist features in that rhetoric, the manual worker idealisation fundamentally carried an individualistic tendency. It is argued that this idealisation, or workerism, is a fruitful object for further analyses.
