Urban growth machine

Urban growth machine is an influential thesis of urban politics that suggests the objective of growth unites otherwise pluralistic interests in relation to a city. The thesis is situated within a broader theory about the commodification of place, where place is understood to be socially and economically valued land. Its key premise is that coalitions of actors and organizations (i.e. growth machines), all sharing an interest in local growth and its effects on land values, compete with growth machines elsewhere for scarce mobile capital investment, while simultaneously attempting to gain the tacit support of local publics for such urban growth. Following an introductory overview, this entry discusses the urban growth machine in two main parts. The first part sets out the key concepts underlying the growth machine thesis: use value, exchange value and place; place entrepreneurs; growth machines and their allies; competing for mobile capital; and promoting growth as a public good. The second part identifies core issues and debates in relation to the thesis (particularly those made by human geographers), including critiques of: the property focus; the human agency focus; difficulties with international comparison; the conceptualization of local dependency and scale; and the relationship of political projects with local feeling

Generating References in Naturalistic Face-to-Face and Phone-Mediated Dialog Settings

During dialog, references are presented, accepted, and potentially reused (depending on their accessibility in memory). Two experiments were conducted to examine reuse in a naturalistic setting (a walk in a familiar environment). In Experiment 1, where the participants interacted face to face, self-presented references and references accepted through verbatim repetition were reused more. Such biases persisted after the end of the interaction. In Experiment 2, where the participants interacted over the phone, reference reuse mainly depended on whether the participant could see the landmarks being referred to, although this bias seemed to be only transient. Consistent with the memory-based approach to dialog, these results shed light on how differences in accessibility in memory (due to how these references were initially added to the common ground or the media used) affect the unfolding of the interaction

Enhancing geological skills through tactile learning with interactive multi-layered three-dimensional printed geological models of southern Ontario.

In the digital age we often forget about the immense value of tactile learning. In other words, learning by touching and moving (i.e., assembling and disassembling) physical objects. Here we introduce the newly developed three dimensional (3D) printed models created by the Oil, Gas, Salt Resource Library that provide an unprecedented regional 3D perspective of the subsurface geology of southern Ontario. These innovative models simplify data from thousands of borehole records that are part of a 3D digital model focusing on the Paleozoic bedrock in southern Ontario (Carter et al. 2021). The 4-layer multi-coloured 3D print models are highly simplified versions of the 52-layer digital models. Nevertheless, the physical model encapsulates numerous aspects of the basin stratigraphy, geometry, and topography. Piloting the use of 3D printed geological models in undergraduate university courses (future Geoscientists and Geologic Engineers) in the form of laboratory exercises has shown to successfully bridge learning gaps in regard to conceptualizing spatial features (i.e., lateral extent, vertical thickness, and aspect of geologic layers), temporal context (i.e., relative age and preserved or missing layers) and economic resource formations (i.e., salt, water, oil, gas). The 3D print models also help students connect field observations with geologic interpretations (i.e., surficial mapping, subsurface borehole data to 3D surfaces, geometric shapes) as well as relating subsurface geology to surface features (i.e., landforms like escarpments and location of resources). In this workshop we will demonstrate the use of 3D printed models needed to bridge vital gaps in knowledge between real digital data and everyday life, applicable to the Geosciences. And then ask for help reflecting upon the use and impact of 3D printed models in other disciplines. Please bring your own device (smartphone, laptop, tablet) so you can experiment with resources and explore potential avenues to improve teaching and learning

Capturing egocentric biases in reference reuse during collaborative dialogue

Words that are produced aloud—and especially self-produced ones—are remembered better than words that are not, a phenomenon labeled the production effect in the field of memory research. Two experiments were conducted to determine whether this effect can be generalized to dialogue, and how it might affect dialogue management. Triads (Exp. 1) or dyads (Exp. 2) of participants interacted to perform a collaborative task. Analyzing reference reuse during the interaction revealed that the participants were more likely to reuse the references that they had presented themselves, on the one hand, and those that had been accepted through verbatim repetition, on the other. Analyzing reference recall suggested that the greater accessibility of self-presented references was only transient. Moreover, among partner-presented references, those discussed while the participant had actively taken part in the conversation were more likely to be recalled than those discussed while the participant had been inactive. These results contribute to a better understanding of how individual memory processes might contribute to collaborative dialogue

Practical strategies to stabilize a nanosatellite platform with a space camera and integrated mechanical parts

The growth and speed of nanosatellite capabilities has led to an increasing demand on the respective attitude control systems. Typically, nanosatellites utilise minaturised reaction wheels for 3-axis stabilisation/manoeuvres, which are desaturated using magnetorquers. Small space telescopes have been deployed from nanosatellites in the past with capability ever increasing to push the limit of detectors. Previous work has established the feasibility of achieving GSD of 0.7 m in low Earth orbit for a 2.5 U CubeSat using deployable mirrors from a 400 km orbit. The dynamic model of nanosatellite with the telescope + the deployed mirror systems will be built in this research work. The deployed mirror system will use a diamond turned mirror - it's an off axis paraboloid. The mirror would be light-weighted as much as possible, i.e. the back surface would be carved away with good thermal stability. The mechanisms for mirror systems may use methods like minature geared motors, stiction motors and shape memory alloy hinges. The sensoring and directing of the mirror surface will use an image based detection methods. A closed loop control of the mirror position will be used to iterate to a fully aligned system. This work also considers control strategies to stabilise such a platform against the effects of firstly, the external aerodynamics and secondly, any internal disturbances induced by and the movement of focussing elements. A pointing accuracy of 5-10 arcsec for a 20 min observation over the UK is targeted at a baseline orbit of 350 km sun-synchronous. Following an initial baseline to establish current state-of-art both based on in-orbit performance and off-the-shelf subsystems available to the market within the constraints of a 3U nanosatellite system, a number of feed-forward/feedback control loops and sensor systems are studied to determine a simple process for compensating for the motion
