Self-guided tours for museums require authors to define a learning objective, research content, design graphics, and implement inclusive interpretive methods. However, museum education literature does not provide clear, comprehensive direction for these complex projects. By recounting the development of a self-guided tour of Judiciary Square for the National Building Museum in Washington, DC, this thesis assesses the value and limitations of theoretical literature in practice. It introduces additional research methods and approaches to address project components that museum education literature overlooks.

When the eyes fixate at a point in a visual scene, small saccades rapidly shift the image on the retina. The effect of these microsaccades on the latency of subsequent large-scale saccades may be twofold. First, microsaccades are associated with an enhancement of visual perception. Their occurrence during saccade target perception should, thus, decrease saccade latencies. On the other hand, microsaccades likely indicate activity in fixation-related oculomotor neurons. These represent competitors to saccade-related cells in the interplay of gaze holding and shifting. Consequently, an increase in saccade latencies after microsaccades would be expected. Here, we present evidence for both aspects of microsaccadic impact on saccade latency. In a delayed response task, participants made saccades to visible or memorized targets. First, microsaccade occurrence up to 50 ms before target disappearance correlated with 18 ms (or 8%) faster saccades to memorized targets. Second, if microsaccades occurred shortly (i.e., < 150 ms) before a saccade was required, saccadic reaction times in visual and memory trials were increased by about 40 ms (or 16%). Hence, microsaccades can have opposite consequences for saccade latencies, pointing at a differential role of these fixational eye movements in preparation of motor programs.

This thesis offers new models for participatory and performative interventions in sites of heritage tourism through a theorized practical engagement. Drawing on both Tourism Studies and Performance Studies, the primary aim of these interventions is to reveal and provoke ways of seeing and using these sites as places of multiple meanings rather than as ones constricted and bounded by normative heritage narratives in their production and management. The experimental phase of the project discussed in the thesis includes three contrasting case studies: GeoQuest, Sardine Street, and Water Walk. These are each analysed and evaluated through my development of a ‘mythogeographic’ framework that includes the performative techniques of layering, rhizomatic interweaving, the making of 'anywheres' and the self-mythologising of the activist. The thesis charts a trajectory through praxis, from developing models for ambulatory, signage-based and ‘mis-guided’ interventions to be undertaken by performance ‘specialists’, towards a dispersal of their tactics for use by heritage tourists in general. It thus describes a related change in the balance of the research methodology from ethnographic participant observation towards practice-as-research (PaR), the latter of which both generated and enacted knowledge and understanding. This PaR took the form of various visits and forays to and across heritage sites and landscape, and also the production of a ‘toolkit’ of handbook, pocketbook, website and online short films for the dispersal of tactics and a strategy that is eventually called ‘counter-tourism’. The thesis thus includes the publications A Sardine Street box of tricks, Counter-tourism: the handbook, Counter-tourism: a pocketbook and the DVD, Tactics for counter-tourism, as well as their fully theorized critical contextualisation. These represent a PaR enquiry that attempts to creatively express my research findings from productions made in the field through a popular form of writing and presentation that is capable of inspiring general, ‘non-specialist’ tourists to make their own performance interventions in heritage sites.

Objectives: To evaluate and compare an experimental surgical navigation system (ESNS) in implant placement accuracy to static planning and transfer systems. Material and Methods: Partially edentulous, surgical typodonts were used to simulate prosthetically-driven osteotomies in preclinical setting. After cbCT acquisition the DICOM files were used to reverse plan and fabricate surgical guides. Manual placement, three static guiding systems and ESNS were compared. Eight osteotomies per jaw were transferred to 10 typodonts in five series, resulting in 400 osteotomies by 3 operators, each modality. Lateral, vertical, total and angular deviations were measured and compared. Results: Computer-assisted systems were comparable and provided superior precision laterally and in angulation, but not vertically; implants placed in free-end positions were less accurate. Conclusions: All computer-aided methods showed less than 2 mm or 5 degrees error on average, which needs to be considered in clinical practice.
