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).

Competitive walking football, an international sport that is less than 10 years old, has great potential to help address the international problems of sedentarism and obesity as a unique form of team-based competitive exercise. While recent research has documented the energy cost of women engaged in match play walking football (Heil et al. IJPEFS 2017), no such data yet exists for men’s teams. PURPOSE: This study sought to characterize the metabolic intensity of match play walking football for one men’s team during successive matches at the 2019 International Walking Football Federation World Cup competition. It was hypothesized that metabolic intensity (i.e., metabolic equivalents, or METs) during match play would meet or exceed the established thresholds for improving physical health and disease risk (≥3.0 METs). METHODS: The Singaporean men’s team (Mean±SD: 58±6 yrs age; 26.6±5.4 kg/m2 BMI; n=9) was monitored during a semi-structured warm-up (WU) and then during 7 successive 15-min competitive matches (M1-M7), all of which happened during a single day. All matches were played at the Leyton Orient outdoor football stadium (East London, England) that was split into four regulation mid-sized fields (40 m x 20 m) under warm and mildly humid ambient conditions (79-81° F; 38-43%). Predicted METs were derived from accelerometry-based activity monitors (AM) that were worn by each player within a neoprene waist pack. The AM data were later downloaded, transformed to units of energy expenditure, and then converted to METs using standard algorithms. A one-sample t-test was used to compare each mean predicted MET value (WU + M1-M7) to the 3.0 MET threshold and a Bonferroni corrected alpha of 0.006 (0.05 overall alpha). RESULTS: Average MET values for the WU (Mean±SE: 4.3±0.06 METs), as well as all seven matches (M1: 4.3±0.09, M2: 4.1±0.07, M3: 4.2±0.09, M4: 4.4±0.10, M5: 3.9±0.12, M6: 3.9±0.14, M7: 4.1±0.10 METs, respectively) exceeded the 3.0 MET threshold (P\u3c0.001). CONCLUSION: The results of this study support previous research with women’s walking football that the metabolic intensity of competitive walking football typically meets or exceeds the 3.0 MET threshold for promoting positive changes in both metabolic fitness and cardiovascular health risk.

Bebouwen van daken verdient nieuwe impuls: Systematisch bronnenonderzoek toont leemte in kennis aan
No full textHet bebouwen van daken leek kort na de eeuwwisseling aan populariteit te winnen. Nu zijn het bijna alleen nog wat eigenaar-bewoners die er heil in zien. Misschien is de economische crisis hier debet aan. Duidelijk is wel dat deze aanpak een impuls nodig heeft, bijvoorbeeld in de vorm van een spraakmakend project of goed onderzoek.OTBArchitecture and The Built Environmen
Hylomorphism: what’s not to like?
No full textThe paper comprises an attempt on the part of the author to understand what hylomorphism is, both in its original Aristotelian guise, and in recent work by philosophers who defend what they call hylomorphism. Two species or strands of hylomorphism are identified and discussed. Universals, essences, and substantial and accidental forms make cameo appearances, and the implications of an Aristotelian ontology of stuffs are explored
Enhanced Sparse Depth Reconstruction Using Edge and Temporal Information: An Application to Micro Air Vehicles
No full textThe reconstruction of dense depth maps is of great value to resource-constrained Mirco Air Vehicles (MAVs), in the pursuit of achieving autonomous flight with a high situational awareness. Most MAVs implement sensing methods which provide a sparse depth map, limiting their capabilities significantly. This article introduces two novel methods to enhance existing depth reconstruction algorithms in terms of geometric reconstruction, depth approximation and computational time. The first contribution is the introduction of a novel method that includes edge information from the image-domain into the depth-regularization problem. This to enhance the retrieval of the complete scene geometry. The second contribution is a novel scheme which includes temporal information in the reconstruction approach, allowing extremely sparse depth scenes to be reconstructed. By estimating the geometric transformation with optical flow, previous depth reconstructions can be used as initial solutions for the current depth-regularization problem. Empirical results show a consistent reduction reconstruction error, while at the same time reducing the computational time. Qualitative estimation shows significant improvement in the retrieval of scene geometry.Aerospace Engineering | Control & Simulatio
