Photography today is based more in editing and manipulation than in the physical capturing of the photo. The pervasiveness of photo editing is only going to increase; however, whether an edited photo remains true to the original photo, let alone the original scene, is left for the photographer to determine. Photographers attempt to create the "perfect" image and are willing to sacrifice the original photo in the process. The finished product becomes in many cases an entirely different photo from the original, to the extent that it is more a product of the editing software than the actual camera. My project takes the form of a photo-editing manual, viewable in both physical and digital format, and an exhibition of the final images. None of the images are so extreme that it is immediately clear that they have been manipulated; however, as they are all images of Scripps College, people who are familiar with the campus will be able to recognize that something is off. I see these images as products of editing software more than products of a camera. I have exaggerated commonly used editing techniques to draw attention to their excessive use in photography today. In the manual, the manipulation and changes suggested become gradually more extreme, so that if the reader does not a first question the instructions, he or she will be sure to by the end.

This thesis describes my work on the development of optical trapping techniques for manipulating airborne particles. Although many of the basic principles are similar to those used in more conventional colloidal experiments, there are many differences which have been described and investigated in detail in this work. Basic characterisation measurements are made, such as axial Q and sample size selectivity, for a number of sample liquids in a basic optical tweezers setup. Performance at 532nm and 1064nm were compared and shown to be very similar, despite increased absorption in the infrared. A successful method was developed for the optical trapping of solid aerosol particles, allowing a direct comparison between similar particles suspended in both the gas and liquid phase. A single beam levitation trap was developed for transporting liquid aerosols to allow multiple chemical measurements to be made on a single droplet. Performance between Gaussian and Bessel beams was compared for various liquids, with guiding distances of several millimetres being achieved with the Bessel beam geometry. An experiment to demonstrate lasing within an optically tweezed droplet was also performed and spectra were taken. Although strong resonance modes were evident, the data was not conclusive. However, it is likely that a redesign of the experiment would be successful. These techniques have extended research capabilities in the areas of both optical trapping and atmospheric chemistry, allowing the detailed study of single aerosol particles in the 1-10 μm range.

Clinical trials have shown that core strengthening is beneficial for patients with low back pain. According to the literature, core strengthening consists of activating the trunk musculature in order to stabilize hypermobile symptomatic joints and thus lessen mechanical stress to the spine. Spinal manipulative therapy has also proved itself to be beneficial, particularly in the case of post-natal low back pain sufferers, as manipulation may correct hypomobility associated with spinal subluxations. Literature suggests that spinal manipulative correction of spinal subluxations in combination with core stability exercises, that stablise symptomatic hypermobile joints, may have more advantages than using these interventions singularly in the treatment of post-natal low back pain. However, the combination of a core stability muscle training program with spinal manipulative therapy has yet to be investigated. In order to choose the most appropriate therapy for managing this condition, it is essential for research to be carried out to identify the most effective treatment, which would allow for better overall management of low back pain during the post-natal period. Therefore this study was designed to establish the effectiveness of a combined protocol of spinal manipulation and core stability exercises in the treatment of post-natal mechanical low back pain and to establish whether this protocol should be utilized routinely in the management of this condition. / M

A dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban Institute of Technology, 2002. / Plantar fasciitis (PF) is a syndrome that causes pain at the insertion of the plantar fascia to the medial calcaneal tubercle of the calcaneaus. This syndrome has been described as an overuse injury with subsequent inflammation at the insertion of the plantar fascia to the bone. The literature describes inflammatory changes that occur within the body and attachment of the plantar fascia, together with biomechanical aberrances that may be the result of the PF. The purpose of this study was to determine the relative effectiveness of pulsed ultrasound as an adjunct to foot manipulation in the treatment of plantar fasciitis. The foot manipulations are used to correct the biomechanical abnormalities, while the pulsed ultrasound is used for its anti-inflammatory properties. The combination of pulsed ultrasound and foot manipulation was compared to foot manipulation alone to determine if this ultrasound manipulation combination had any beneficial effect over and above foot manipulation alone. Thus determining whether it is of importance to o approach and treat both aspects of the syndrome described. This was a prospective, randomised, comparative controlled trial. Forty subjects were diagnosed with plantar fasciitis and chosen to participate in the study. They were subsequently divided into two groups (Group A and Group B) of twenty. Group A was the experimental group receiving foot manipulation and ultrasound as treatment, and Group B, the control group received foot manipulation alone as treatment. Each subject received six treatments within a period of three weeks, with a seventh follow-up within one week of the sixth treatment. There was no treatment at the seventh consultation; this was used for obtaining subjective and objective readings. Subjective assessment was by means of the Foot Function Index, and objective was by means of the manual algometer. Both the subjective. and objective readings were taken prior to the first, sixth and at the seventh (final) consultations. / M

To compare the bowling speed of Action Cricket fast bowlers pre-post intervention. To determine the correlation between change in bowling speed immediately post-intervention to change in trunk flexion and lateral flexion ROM immediately post-intervention. To determine the association between change in bowling speed immediately postintervention and the subjects' perception of change in bowling speed. Methods: Forty asymptomatic Action Cricket fast bowlers were divided into four groups of ten each. Group 1 received lumbar spine manipulation, Group 2 received thoracic spine manipulation, Group 3 received combined thoracic and lumbar spine manipulation and Group 4 received the sham laser intervention (placebo). Pre- and post-intervention trunk flexion and lateral flexion ROM and bowling speed were measured using a digital inclinometer and a SpeedTrac\x99 Speed Sport Radar. The subjects' perception of a change in bowling speed post-intervention was also recorded. SPSS version 15.0 was used to analyse the data. Twotailed tests were used in all cases. Results: Trunk flexion and lateral flexion increased significantly (p < 0.05) post-spinal manipulation. There was a significant increase in bowling speed post-thoracic (p = 0.042) and postcombined manipulation (p < 0.000). A significant yet weak positive correlation (p = 0.003; r = 0.451) was seen in change in bowling speed and change in thoracic flexion and lateral flexion. There was no significant difference in the percentage subjective change by intervention group (p = 0.217). Conclusions: Spinal manipulation is a valid intervention for short-term increase in bowling speed. / M

Dissertation submitted in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, Durban University of Technology, 2011. / Purpose: Chronic ankle instability (CAl) is characterised by ankle pain, weakness, edema, crepitus, adhesions, restrictions and ligamentous laxity. Various treatment options target a variety of aspects of this condition. However, there is a paucity of literature with regards to combined treatment choices. The purpose of this study was to investigate the relative effectiveness of combining manipulation with rehabilitation, compared to rehabilitation only, in participants with CAl. Methods: The study was a single blinded, randomised and comparative clinical trial at a chiropractic day clinic. Thirty participants with grade I and II CAl were recruited and randomly allocated into one of two treatment groups. Fifteen participants received a combination of manipulation and rehabilitation (coupled peroneal muscle strengthening and proprioception) and fifteen received the rehabilitation only programme. All six treatments in each group were conducted over five weeks. Results: A P value of <0.05 was considered statistically significant. The intra-group outcomes in the Manipulation and Rehabilitation Group indicate that statistically significant improvements were achieved for all six parameters in this study (VAS p<0.001; FAOI p<0.001; Algometer p<0.001; motion palpation p<0.001; WBO p=0.001 and BBS p<0.001). This is in comparison to the three outcomes where statistical significance was achieved (VAS p<0.001; FAOI p<0.001 and BBS p<0.001) in the Rehabilitation only Group. Inter-group analysis revealed statistically significant improvement in favour of the Manipulation and Rehabilitation Group for VAS (p<0.001); algometer readings (p=0.002) and Motion palpation findings (p<0.001). Conclusions: The findings of this study show that manipulation in combination with rehabilitation is relatively more effective than rehabilitation only for most outcome measures.

Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2007. / Each healing encounter, and every treatment, has specific and non-specific treatment effects. Non - specific effects, or placebo effects, are the benefits felt by the patients because of the nature of the healing encounter. Although difficult to quantify and control, a number of authors recognize that the non-specific component of management has an additive effect on the overall clinical outcome. It has been reported that due to the physical interaction and social nature of chiropractic, there is a strong non-specific component in the management process, but to what extent it facilitates in the healing encounter is unknown. It has also been shown that spinal manipulation has a clinical effect which exceeds that of placebo; therefore it is possible for its effect to be muted or amplified, depending on the presence or absence of non-specific effects. For the above reasons this study was conducted in an attempt to map the size of the nonspecific effect in the healing encounter by manipulating the practice setting in which the patients were treated. This was achieved using a prospective, randomised, comparative clinical experiment consisting of 60 individuals with Low Back Pain (LBP), selected by convenience sampling. Individuals were then divided into 2 groups of 30. The IV first group's treatment consisted of the standard diversified method of manipulation in a Clinical Research Setting, and the second group received the same treatment except the treatment took place in a Normal Practice Setting. / M

The results of this study would indicate to Chiropractors which specific types of adjustments, used for the treatment of mechanical neck pain, would potentially increase the cervical range of motion and / or decrease pain experienced by the patient and thus lead to a more effective treatment protocol. The outcome of the study will help clinicians select the more appropriate treatment for patients based on the subjective and objective outcomes. / M

Submitted in partial compliance with the requirements for Master’s degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background Functional dyspepsia is a chronic pain/discomfort centred in the upper abdomen in the absence of any known structural cause. Epidemiological studies have shown that functional dyspepsia is a common complaint affecting all population groups that over time places considerable financial strain on public and private resources due to frequent doctors’ visits and expensive diagnostic procedures. The development of non-surgical and non-pharmaceutical treatments of functional dyspepsia would not only make economic sense but would also provide a means to improve patients’ quality of life in the least invasive way possible. Although not traditionally seen to be within the chiropractic scope of practice, anecdotal evidence suggests that chiropractic care and management may have the ability to alleviate visceral symptomatology. Objectives The purpose of this placebo controlled pilot study was to evaluate the preliminary effects of chiropractic manipulation versus inactive laser in the treatment of adult patients suffering from functional dyspepsia. Due to the small sample size, time and budgetary constraints it was hypothesised that the dyspepsia symptoms of participants treated with active chiropractic manipulation would not respond more favourably to the treatment, nor would these patients experience a greater improvement in terms of quality of life, compared to those participants receiving placebo treatment. Method Thirty participants with pre-diagnosed functional dyspepsia were selected after being screened according to the inclusion and exclusion criteria identified by the researcher. These participants were then divided into two groups using consecutive sampling. Data was collected at the Chiropractic Day Clinic at the Durban University of Technology. Group A received an active chiropractic manipulation using diversified technique to pre-identified levels in the cervical, thoracic and lumbar spine. Group B received inactive laser to pre-identified levels in the cervical, thoracic and lumbar spine. Both groups received one treatment a week for three weeks. The fourth and final consultation consisted only of data capturing. At each visit both groups of participants filled in three validated questionnaires: The numerical pain rating scale; PAGI-SYM physical symptom assessment; Results Results were statistically analysed using IBM SPSS version 20 and a p value ≤ 0.05 was considered to be statistically significant. Repeated measures ANOVA testing was used to assess the effect of each of the treatments separately and to assess the comparative effects of the spinal manipulation vs the placebo. Conclusion and Recommendations The gathered results and analysis were statistically insignificant. Clinical improvement in their symptomotology was however noted within both groups over the trial period in terms of treatment received and their perceived quality of life, symptomatology and pain levels. Both groups tended to have reduced pain and discomfort over time, improved: emotional distress, sleep disturbance, food problems, vitality, post-prandial fullness and abdominal pain. This study should be repeated with selected outcome measurements, and perhaps objective outcome measurements, and a larger sample size in order to determine any benefit. / M
