An Interview with Cass R. Sunstein: Author of The World According to Star Wars
No full textThe guest editors of special issue 12, Jason W. Ellis and Sean Scanlan, interview Cass R. Sunstein, the Robert Walmsley University Professor at Harvard, where he is founder and director of the Program on Behavioral Economics and Public Policy. He is the author of many books, including the bestseller Nudge: Improving Decisions about Health, Wealth, and Happiness (with Richard H. Thaler). His 2016 book The World According to Star Wars attempts to understand the Star Wars universe in ten chapters through the lenses of Sunstein’s academic interests, namely: culture, sociology, psychology, behavioral science, and political science. The book is both personal and theoretical, practical and academic. It takes accurate measure of the genesis of the movies, the movies themselves, and briefly, but trenchantly, it examines concepts such as reputational cascades and speculates on what Star Wars can teach viewers about constitutional disputes

Social facilitation: salience and mediated, anticipatory, and residual presence
No full textSocial facilitation is the oldest experimental concept in social psychology. Throughout decades of social facilitation research, social presence has typically been viewed as a dichotomous variable which affects individuals while performing a task. However, this dissertation attempts to investigate whether social presence may be viewed as continuous variable, differing on the salience of presence. In addition, it seeks to determine whether changes in performance can be elicited by prior social presence (residual presence) and the expectation of future social presence (anticipatory presence). Study 1 compared the effects of 6 different levels of presence (absence, artificial presence, passive presence, implied presence, embodied presence, and active presence) on simple and complex task performance. It provides evidence that the various levels of social presence did have a differential impact on participants. From the questionnaire responses, social presence was able to be classified into three distinct categories: low (absence, artificial and passive presence), intermediate (implied presence), and high salience (embodied and active presence). Study 1 also provides some support for the expectation that presence results in simple task facilitation. However, instead of an expected linear relationship between salience of presence and simple task enhancement, a quadratic inverted U-shaped curve was observed. Implied presence, a type of presence of intermediate salience, produced the strongest effects. Study 2 showed that social presence can enhance simple task performance even after the stimulus has been removed (residual presence). Study 2 also provided some indication that anticipating a supervisor could cause social facilitation effects even before the supervisor’s arrival. Questionnaire responses showed that participants expecting the presence of a supervisor, like those exposed to residual presence, were more affected on perceived distraction, immediacy, impact, and stress compared to control participants. Implications of the present results provide the rationale for a modified conceptualization of social facilitation.Ph. D.Includes bibliographical referencesby Jason Matthew Glushako

FLUENT models of furnace tubes and their use to guide geometric changes
No full textA modified straight-through single-ended furnace tube is modeled in FLUENT. The modification was created in order to save on fuel and prolong the life of the tubes. The research described in this thesis is based on an ongoing research project with Gas Technology Institute and North American Manufacturing Company. The objective of this research is to determine if simple modifications to an existing furnace tube setup can be made to decrease tube temperatures and emissions. Another important objective is to make the temperature of the outermost tube, radiant tube, more uniform in the axial direction, since the heat radiating off of it will dictate the quality of the manufacturing process of the pieces placed in the furnace. This thesis will describe the process in which creating this model was done, and solutions to problems that occur. It will explain the setup of the programs used, and the ways to check for quality meshes. The concerns of the existing setup will be discussed based on the model. To address these concerns, a few modified models are also presented in order to show how ideas of geometric changes were either supported or disproved. These results show that depending on the location at which increased mixing is caused by varying the geometry, the combustion will either lengthen or shorten the flame length. Optimal results were found to be difficult to predict, but by controlling the mixing at the initial stages, and causing mixing downstream of the initial combustion, certain objectives were satisfied.Mechanical Engineerin
Study of simplified models of aircraft structures subjected to generalized explosive loading
No full textThis dissertation develops a simple methodology for estimating the maximum elastic-plastic deformation of thin, rectangular plates due to an exponentially decaying pressure pulse. Initially, only small plates, representative of aircraft skin panels, and uniformly distributed pressures are examined. The deflections predicted by this procedure are compared with those attained from finite element analysis for various plate dimensions and blast intensities. Material properties and boundary conditions are also varied. It is found that the current, clamped single-degree-of-freedom model is generally a much better predictor of deflection than its simply supported counterpart, although both show average errors of less than 15% compared to finite element results. The deviations between all of the models tend to decrease as surface area decreases, or as plate thickness and aspect ratio increase. A means of approximating permanent plate deflection is also suggested, which favorably compares with previously published experimental results for square, aluminum plates.
The aforementioned procedure is then extended for use with larger geometries, namely a wider fuselage section and a panel of an onboard luggage container, and nonuniform pressures. A generalized distribution function is developed to account for nonuniformities consistent with detonations at a small standoff distance. Moreover, two normalized criteria are proposed to determine when these nonuniformities can be ignored. In addition, large discrepancies are found in calculated deflections when incorporating the current structural model and the blast parameter data from two commonly used sources for both uniform and nonuniform loading cases. As a result, uncertainties in these data are thoroughly examined, which leads to confidence bounds being placed on all calculated deflections through a Monte Carlo scheme. This, in turn, allows for the generation of probability of failure curves.
Suggestions for improving the current loading and structural models are also discussed. Finally, the method of analysis for plates is preliminarily extended for the blast loading of thin, cylindrical shells. The various topics covered and simplified models proposed are useful to both the experimentalist and designer of blast resistant structures.Ph.D.Includes bibliographical references (p. 141-147)
Swirling flow of viscoelastic fluids
No full textDeposited with permission of the author. © 1998 Jason R. Stokes.The ability to understand and predict the flow behaviour of non-Newtonian fluids in swirling flow is industrially important for the efficient design and performance of processes which utilise fluids with complex rheological properties. In particular, fluids with elastic properties are not well described by non-Newtonian constitutive models, such that predictions using such models must be carefully validated. A benchmark problem is proposed here which provides a well defined geometry to study the swirling flow of non-Newtonian fluids as a test case for the validation of constitutive models. The confined swirling flow utilised is a torsionally driven cavity where the test fluid is confined in a cylinder with a rotating bottom lid, and stationary side walls and top lid. The flow field is three-dimensional and consists of both a primary motion, which is directed azimuthally, and a secondary motion, which is located in the radial and axial plane of the cylinder and driven by inertial and/or elastic forces
