The impact of scale on children’s spatial thought: a quantitative study for two settings in geometry education
No full textIn this book, Cathleen Heil addresses the question of how to conceptually understand children’s spatial thought in the context of geometry education. She proposes that in order to help children develop their abilities to successfully grasp and manipulate the spatial relations they experience in their everyday lives, spatial thought should not only be addressed in written or tabletop settings at school. Instead, geometry education should also focus on settings involving real space, such as during reasoning with maps. In a first part of this book, she theoretically addresses the construct of spatial thought at different scales of space from a cognitive psychological point of view and shows that maps can be rich sources for spatial thinking. In a second part, she proposes how to measure children’s spatial thought in a paper-and-pencil setting and map-based setting in real space. In a third, empirical part, she examines the relations between children’s spatial thought in those two settings both at a manifest and latent level. About the author Cathleen Heil is a research assistant at the Institute of Mathematics and its Didactics at Leuphana University Lüneburg. She received her PhD under supervision of Prof. Dr. Silke Ruwisch. She is currently a fellow of Deutsche Telekom Stiftung, examining how learning environments involving maps may improve children‘s spatial thought in geometry education
Community development for whom?: the role of community development corporations in the neoliberal city
No full textCommunity development corporations (CDCs) emerged in the 1960s as grassroots neighborhood organizations which called for investment of government resources in marginalized neighborhoods. Beginning in the 1980s, CDCs became viewed as a market solution to the administration of affordable housing. This thesis examines the role of CDCs today. Particularly, whose interests are being served by CDCs—marginalized residents or other constituencies in the city? Based on interviews with Detroit CDC executive directors, residents, foundation program officers, and city officials, this project considers whose preferences are represented in the strategic initiatives of CDCs, who can hold these organizations accountable, and who benefits from the outputs of the organizations' work.
The results suggest that CDCs may easily be coopted and used to legitimize neoliberal redevelopment agendas. CDCs today are being positioned as neighborhood representatives which are well-suited to bring financial and programmatic resources into neighborhoods and advocate on behalf of residents. The supposed resident-controlled character of CDCs is central to this positioning, but CDCs often fail to maintain majority resident boards, and funders expect CDCs to advance their own neoliberal redevelopment priorities for Detroit neighborhoods.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Melissa Heil, accepted the attached license on 2016-05-30 at 10:13.The student, Melissa Heil, submitted this Thesis for approval on 2016-05-30 at 10:22.This Thesis was approved for publication on 2016-06-01 at 16:59.DSpace SAF Submission Ingestion Package generated from Vireo submission #9629 on 2016-11-10 at 12:24:18Made available in DSpace on 2016-11-10T18:39:02Z (GMT).

“How much are our lives worth?” Water, reproduction, and geographies of American austerity
No full textAusterity policies have been a dominant governance strategy in America’s rustbelt cities since the 2008 financial crisis. These policies call for balanced budgets, reduced expenditures, and deepened dismantling of public resources (e.g., shuttering of social service programs, selling-off of public assets) to bolster government budgets and economies. Austerity policies advance a socially regressive redistribution of resources. It is a governance agenda which relies on logics of division to construct “others” who will bear the burden of restoring government budgets to a place of fiscal health.
This dissertation examines the execution and impacts of austerity governances in a study of two rustbelt cities, Flint and Detroit. Two issues are examined. First, it interrogates the techniques used by austerity governances to divide people and construct certain populations as debtors who can be subject to dispossession in the name of economic necessity. Such dispossessions rupture people’s rhythms and practices of survival in their day-to-day lives. Second, this project chronicles the changing spaces, practices, and politics of social reproduction that follow from implementing austerity as non-state actors (e.g., non-profits, activists, individuals) take on increased responsibility to provide for human welfare. Together, this research uncovers a complex constellation of knowledges, practices, and imaginaries that are invented and mobilized to drive austerity and excavates their outcomes in the realm of social reproduction.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-05-01The student, Melissa Heil, accepted the attached license on 2020-04-24 at 08:20.The student, Melissa Heil, submitted this Dissertation for approval on 2020-04-24 at 08:31.This Dissertation was approved for publication on 2020-04-27 at 09:41.DSpace SAF Submission Ingestion Package generated from Vireo submission #15058 on 2020-08-25 at 17:40:54Made available in DSpace on 2020-08-27T00:50:01Z (GMT).

Learning the Right Model from the Data
No full textSummary. In this chapter we discuss the problem of finding the shift-invariant space model that best fits a given class of observed data F. If the data is known to belong to a fixed—but unknown—shift-invariant space V (Φ) generated by a vector function Φ, then we can probe the data F to find out whether the data is sufficiently rich for determining the shift-invariant space. If it is determined that the data is not sufficient to find the underlying shift-invariant space V , then we need to acquire more data. If we cannot acquire more data, then instead we can determine a shiftinvariant subspace S ⊂ V whose elements are generated by the data. For the case where the observed data is corrupted by noise, or the data does not belong to a shift-invariant space V (Φ), then we can determine a space V (Φ) that fits the data in some optimal way. This latter case is more realistic and can be useful in applications, e.g., finding a shift-invariant space with a small number of generators that describes the class of chest X-rays.Fil: Aldroubi, Akram.

Invariance of a shift-invariant space
No full textA shift-invariant space is a space of functions that is invariant under integer translations. Such spaces are often used as models for spaces of signals and images in mathematical and engineering applications. This paper characterizes those shift-invariant subspaces S that are also invariant under additional (non-integer) translations. For the case of finitely generated spaces, these spaces are characterized in terms of the generators of the space. As a consequence, it is shown that principal shift-invariant spaces with a compactly supported generator cannot be invariant under any non-integer translations.Fil: Aldroubi, Akram.

Frames via Unilateral Iterations of Bounded Operators
No full textDynamical Sampling is a superordinate term classifying the set of inverse problems arising from considering samples of a signal and its future states under the iterative action of a linear operator. A central problem in this area is the following: let where . Suppose for we know for some operator . What are conditions on , and that allow the stable reconstruction of ? In this thesis we apply the Dynamical Sampling framework to obtain results regarding reconstructing Paley-Wiener spaces of finite combinatorial graphs.
In separable infinite-dimensional Hilbert spaces, the Dynamical Sampling problem is typically posed the following way: what are necessary and sufficient conditions so that is a frame (where and )? Extending the results in this area by applying tools from the theory of shift-invariant subspaces of the Hardy Space on the bidisc, in this thesis we present necessary and sufficient conditions for systems of the form , where commute, to be a frame.Ph.D
