Belief, Make-Believe, and the Religious Imagination:The Case of the Deus Ex Machina in Greek Tragedy

The chapter opens by making the case for a capacious understanding of the psychology of the religious imagination. Psychological capacities and propensities, it is suggested, are enabling as much as they are constraining, and religious actors creatively employ these capacities and propensities as much as they are unknowingly subject to them. The particular phenomenon for which this notion of the religious imagination is then explored in the bulk of the chapter is the deus ex machina of Greek tragedy; the relevant imaginative capacity is the human propensity for make-believe. The chapter argues that both externally, as a form of make-believe, and internally through details of the dialogue between god and characters, deus ex machina scenes pull systematically in two directions: the religious experience they enable is one in which there is room simultaneously for both belief and disbelief, trust and distrust, commitment and distance. A subsidiary strand of the argument aims to contribute to current debates about the notion of ‘belief’ in scholarship on Greek religion. The chapter emphasizes that ‘belief’ is usefully understood as sometimes including an attitudinal dimension. This attitudinal dimension comes to the fore in the deus scenes

A normative study of cervical range of motion measures including the flexion–rotation test in asymptomatic children: side-to-side variability and pain provocation

Objectives: Cervical movement impairment has been identified as a core component of cervicogenic headache evaluation. However, normal range of motion values in children has been investigated rarely and no study has reported such values for the flexion–rotation test (FRT). The purpose of this study was to identify normal values and side-to-side variation for cervical spine range of motion (ROM) and the FRT, in asymptomatic children aged 6–12 years. Another important purpose was to identify the presence of pain during the FRT. Methods: Thirty-four asymptomatic children without history of neck pain or headache (26 females and 8 males, mean age 125.38 months [SD 13.14]) were evaluated. Cervical spine cardinal plane ROM and the FRT were evaluated by a single examiner using a cervical ROM device. Results: Values for cardinal plane ROM measures are presented. No significant gender difference was found for any ROM measure. Mean difference in ROM for rotation, side flexion, and the FRT were less than one degree. However, intra-individual variation was greater, with lower bound scores of 9.32° for rotation, 5.30° for side flexion, and 10.89° for the FRT. Multiple linear regression analysis indicates that movement in the cardinal planes only explains 19% of the variance in the FRT. Pain scores reported following the FRT were less than 2/10. Discussion: Children have consistently greater cervical spine ROM than adults. In children, side-to-side variation in rotation and side flexion ROM and range recorded during the FRT indicates that the clinician should be cautious when using range in one direction to determine impairment in another. Range recorded during the FRT is independent of cardinal movement variables, which further adds to the importance of the FRT, as a test that mainly evaluates range of movement of the upper cervical spine

Earthquake protection of colonial bell towers in Colima, Mexico with externally prestressed FRPs

A methodology for the seismic vulnerability reduction of old masonry towers with external prestressing is presented. It is applied at the Colonial bell-towers of the Cathedral of Colima, Mexico, characterized for being a high seismic area (M>7.5). The 3D FE models are calibrated with experimental data and assessed through nonlinear static approaches including the seismic demand and an accurate validated masonry model. Based on an extensive parametric study on different configurations of old masonry towers, it is selected an optimal prestressing force and device. The Colonial towers are retrofitted with four prestressing devices of FRPs to convert them into a high energy-dissipative reinforced masonry. The external vertical prestressing is included at key points identified in the seismic vulnerability assessment. This technique is in compliance with the demand for architectural conservation and may be located without drilling and unbounded in order to be fully removable. The seismic performance is enhanced by increasing force, displacement, and internal confinement. It is observed an upgrading of 35% and 20% of displacement capacity. With these results it is corroborated that external vertical prestressing allows a substantial increment of ductility for seismic energy dissipation purposes.ITESO, A.C.Technical University of BraunschweigUniversity of Florenc

Fundamental aspects on the seismic vulnerability of ancient masonry towers and retrofitting techniques

Ancient masonry towers constitute a relevant part of the cultural heritage of humanity. Their earthquake protection is a topic of great concern among researchers due to the strong damage suffered by these brittle and massive structures through the history. The identification of the seismic behavior and failure of towers under seismic loading is complex. This strongly depends on many factors such as soil characteristics, geometry, mechanical properties of masonry and heavy mass, as well as the earthquake frequency content. A deep understanding of these aspects is the key for the correct seismic vulnerability evaluation of towers and to design the most suitable retrofitting measure. Recent tendencies on the seismic retrofitting of historical structures by means of prestressing are related to the use of smart materials. The most famous cases of application of prestressing in towers were discussed. Compared to horizontal prestressing, vertical post-tensioning is aimed at improving the seismic behavior of towers by reducing damage with the application of an overall distribution of compressive stresses at key locations.Technical University of BraunschweigUniversity of FlorencePolytechnical University of Guadalajar

The use of prestressing through time as seismic retrofitting of historical masonry constructions: past, present and future perspective

Unreinforced masonry is one of the oldest construction materials and main component of historical buildings. Masonry is a heterogeneous material with an anisotropic behavior and may fail quasi-brittle during earthquakes. This paper describes the main components and arrangements of historical masonry, seismic vulnerability and existing retrofitting techniques, especially prestressing. Based on the evolution of prestressing, it is developed a future perspective about the use of this technique on cultural heritage. Especial attention may be taken into account when using this technique because the compressive strength may be exceeded, leading to an explosive brittle failure. The correct application of prestressing requires the designing of a compatible device and optimal post-tensioning force that improves strength and ductility without endangering the structure.Technical University of BraunschweigUniversity of FlorencePolytechnical University of Guadalajar
