(1) Background: Missing Middle (MM) housing may be critical to address decreasing housing affordability and to achieve critical density in transit-oriented neighborhoods; however, its production is in decline. We report on a case study of housing development around a new light-rail transit line in the Region of Waterloo, Canada, investigating the puzzle of how a residential building boom coincided with decreasing housing affordability. (2) Methods: Following participatory co-creation and communication of background research characterizing housing demand with stakeholder partners, we created a data narrative arguing that MM housing was desired by residents and profitable for developers and then used it to guide semi-structured interviews with planners and real estate industry stakeholders. Based on these interviews, we developed a qualitative system map and causal loop diagrams that demonstrate interactions between key actors (residents, brokers, planners, developers, and investors) as mediated by boundedly rational real estate demand expectations. (3) Results: Our interviews identify multi-faceted barriers, beyond demand perception, to MM housing development. Systems analysis illustrates how high-density, small-unit high-rise development can become locked in, concurrently locking out MM housing. (4) Conclusions: Our research identifies barriers to MM housing supply by articulating the systemic feedbacks between the planning and land/housing market realms and reveals key leverage points, empowering planners to develop policies that catalyze hoped-for housing market supply responses to increase housing affordability. Based on these findings, we suggest targeted interventions: multi-unit base residential zoning, MM site plan typologies, non-profit and co-op financing, unit-mix requirements, pre-build MM condo purchase by municipalities or non-profits, and MM demonstration projects.
We give an overview and describe the rationale, methods, and testing of the Hubble Space Telescope (HST) Archival Legacy project "SKYSURF". SKYSURF uses HST's unique capability as an absolute photometer to measure the ∼0.2-1.7 µm sky surface brightness (SB) from 249,861 WFPC2, ACS, and WFC3 exposures in ∼1400 independent HST fields. SKYSURF's panchromatic dataset is designed to constrain the discrete and diffuse UV to near-IR sky components: Zodiacal Light (ZL; inner Solar System), Kuiper Belt Objects (KBOs; outer Solar System), Diffuse Galactic Light (DGL), and the discrete plus diffuse Extragalactic Background Light (EBL). We outline SKYSURF's methods to: (1) measure sky-SB levels between its detected objects; (2) measure the integrated discrete EBL, most of which comes from AB 17-22 mag galaxies; and (3) estimate how much diffuse light may exist in addition to the extrapolated discrete galaxy counts. Simulations of HST WFC3/IR images with known sky-values and gradients, realistic cosmic ray (CR) distributions, and star plus galaxy counts were processed with nine different algorithms to measure the "Lowest Estimated Sky-SB" (LES) in each image between the discrete objects. The best algorithms recover the inserted LES values within 0.2% when there are no image gradients, and within 0.2-0.4% when there are 5-10% gradients. SKYSURF requires non-standard re-processing of these HST images that includes restoring the lowest sky-level from each visit into each drizzled image. We provide a proof of concept of our methods from the WFC3/IR F125W images, where any residual diffuse light that HST sees in excess of the Kelsall et al.(1998) Zodiacal model prediction does not depend on the total object flux that each image contains. This enables us to present our first SKYSURF results on diffuse light in Carleton et al. (2022).
The role of public transportation has shifted over the last 2 decades as planners and policymakers increasingly integrate new transportation infrastructure as an economic growth tool that promotes density and desirability. This shift has also positioned new infrastructure as a driver for neighbourhood change and gentrification, leading to the evolution of literature that explores transit‐induced gentrification. As this scholarship grows however, research has become fragmented, as the political economy work, which frames much of gentrification, is antipathetic to the neoclassical perspective that frames transportation research. The resulting inconsistencies have left researchers calling for the integration of new and holistic approaches that can address growing gaps. With transit‐induced gentrification becoming more prevalent across large and mid‐sized cities, and research lacking methodological consistency, this review considers: Can a complex systems thinking framework be used to better understand and address the process of transit‐induced gentrification?
The COVID-19 pandemic brought attention to scarce clinical resource allocation via secondary population-based triage (S-PBT) throughout the international healthcare community. Experiences overseas highlighted the importance of coordinated and consistent approaches to allocating resources when facing overwhelming demand, particularly for critical care. Noting the importance of consistency and the system of devolved governance deployed in Australia, this study aimed to identify and analyse sources of high-level policy that affect Australia’s health system preparedness for the operationalisation of S-PBT. Of the 39 documents reviewed, 17 contained potential references to S-PBT. There was a lack of clear recommendations and guidance to inform S-PBT operationalisation and, where provided, advice conflicted between documents. Many jurisdictions did not detail how S-PBT would be operationalised and failed to delineate stakeholder responsibilities. These results are important as they reveal a lack of high-level jurisdictional policy preparedness for coordinated and consistent S-PBT operationalisation. These results offer insights and opportunities for enhanced disaster preparedness as clinicians, policymakers and academics critically reflect on pandemic responses. The results show a need for enhanced preparedness around the management of overwhelming demand and clinical resource management in Australia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
