Abstract

Housing cost burden—defined as paying more than 30% of household income for housing—has become a central feature of the American stratification system with dire consequences for the health and well-being of adults and children living in burdened households. To date, existing research has largely focused on the overall prevalence and distribution of housing cost burden—that is, the percentage of households that are cost burdened at a given time and differences in exposure to housing cost burden based on race and income using cross-sectional sources of data. To more fully understand the dynamics of housing cost burden among renter households in the United States including the frequency and duration of spells, we use 50 years of longitudinal data from the Panel Study of Income Dynamics (PSID). The analysis reveals that, in contrast to the episodic nature of poverty, housing cost burden is deep, frequent, and persistent for a growing share of American households.

Abstract

Environments, Health, and Safety (EHS) activities are strongly linked to the concept of sustainability in the current construction industry and consequently absorb more financial and managerial attention. One of major obstacles in EHS costing is that most EHS costs are buried in general overhead costs. Therefore, EHS costs lacks transparency, making it hard to allocate EHS costs to relevant construction projects. This paper present a recent study in which a method of activity-based costing (ABC) has been applied to safety costs at a contractor's home office. The list of safety activities, their cost drivers as well as their cost information on one of Korean general contractor is provided. The authors expect that the application of ABC will improve transparency in costing EHS costs as well as allocating EHS costs to projects.

Abstract

During disruptive events and major crises such as the COVID-19 pandemic, essential workers, defined in this study as employees who must continue to make frequent commute trips, play a critical role in maintaining the basic function of society. It is therefore vital for transportation planners and policymakers to ensure that adequate mobility services are provided to meet the travel needs of this group of workers. To better understand essential workers' mobility barriers and inform future transportation policy, this research examines their pre-and during-pandemic commutes, as well as prospects on future commuting, using data from the Transportation Needs Assessment Survey conducted by the University of Washington in Seattle. The results show that, first, over 60% of pre-pandemic public transit riders switched to other modes, especially driving alone. In contrast, almost all the essential workers who drove alone, biked, or walked before the pandemic continued to do so during the pandemic. Second, the shift to driving alone was most pronounced among essential workers with high incomes, whereas public transit remained as a primary mode choice of lower-income groups. As travel distance increased, the probability of driving alone over public transit also went up, although the relationship was not linear. We did not find consistently significant associations between mode choice and other sociodemographic variables. Finally, our analysis indicated that most essential workers anticipated to return to their pre-pandemic commute frequency and mode choice when the pandemic is under control. Transportation planners and policymakers can facilitate mobility for essential workers through planning and policy innovations, especially during disruptive events and major crises.

Abstract

Unsanctioned, unscripted, and seemingly “undesirable” activities have long appropriated urban spaces in routine and sometimes unexpected ways, bringing new meanings and unforeseen functions to those places. In the last decade or so, such practices have inspired a growing movement under the banner of DIY and tactical urbanisms. The growing acceptance of these practices creates important openings in the formalized planning systems for greater fexibility and expedient change. Yet, the institutionalization of previously informal and even subversive acts has resulted in concerns regarding co-optation and de-politicization. This special issue seeks to pivot a refocus towards these unsanctioned and unscripted urban activities as a form of counter-hegemonic spatial practices, distinct from its professionalized and institutionalized counterpart. A range of cases is examined here sharing similar characteristics as challenges against the prevailing social and political paradigm. Key findings include the scalability of guerrilla actions, the fuid shift between overt and covert actions, and the linkage between everyday struggles and organized resistance. This special issue is intended to advance our understanding of urban design by situating it in a broader social, economic, and political praxis that encompasses both formal and informal practices performed by a wide variety of individual and collective actors.

Abstract

Civil society responses including self-help and mutual aid have played an important role in addressing the COVID-19 crisis around the world, including Asia. They represent a form of civic resilience, the ability of citizens and communities to cope with and adapt to social, economic, and environmental disturbances. But how exactly did communities and social groups in Asia self-organize to address challenges during the pandemic, particularly those facing the most vulnerable populations in society? What did these cases have in common? What can we learn from these civil society responses for future planning? What were the roles of researchers, spatial planning professionals, and institutions in strengthening community resilience? This article presents outcomes from a two-part webinar titled "Bottom-Up Resilience" that took place in July 2020 featuring activists, organizers, and researchers from Hong Kong, Manila, Shanghai, Singapore, Taipei, and Tokyo. Preliminary findings include contrasting responses from institutions and civil society actors, how the civil society responses have built upon and expanded trust and empathy in a given place, how civil society responses scale up, and such scalability has depended heavily on solidarity and collaboration. The article further discusses how these efforts represent a form of civic resilience, the continued barriers, and implications for spatial planning practices.

Abstract

Early BEH research addressed influences of toxic environmental exposures, zoning laws, building codes, and healthy housing and communities on asthma, injury, violence, healthy and unhealthy food consumption, mental health, social capital, and health inequities.1 Awareness increased regarding the benefits of denser, more walkable, and less automobile-dependent settings, as well as the accessibility, mobility, and livability needs of the growing aging population. Work on automobile dependence, traffic safety, walking and biking, commuting, and sedentary time was primarily driven by the Robert Wood Johnson Foundation's Active Living Research initiative to promote active living via environment, policy, and practice improvements3,4 Research linked specific building and community features to health outcomes, enabling more effective interventions such as appealing stairways, ample sidewalks, and vibrant activity centers.5 The business case for health promoting, walkable places was documented.6 Unintended consequences, including gentrification and displacement, of interventions aimed at improving health among people from racial and ethnic minority groups and of lower incomes were increasingly recognized, resulting in more research focused on how to mitigate these risks.7 The history of structural racism, segregation, redlining, neighborhood disinvestment, health inequities, and disparities in walkability, housing, and green space access was only recently widely acknowledged.8 Numerous books (Table E, available as a supplement to the online version of this article at http://www.ajph.org) and dozens of BEH measures (e.g., walkability [https://www.wal kscore. com], access to parks [https://www.tpl. org/ParkScore], livability [http://www. livabilitylndex.AARP.org], and brain health [https://cognability.isr.umich. edu]) were also published, reflecting the growth and maturation of the field. The effects of these evolving technologies on land use, housing, economic and community development, traffic patterns, transportation planning and infrastructure, air quality, and associated health outcomes require further research and evaluation (Table G, reference 3).10 PRACTICE Professional organizations across disciplines established BEH committees and working groups (Table F, available as a supplement to the online version of this article at http://www.ajph.org), promoting healthy building and community design through conferences, reports, training, and advocacy (e.g., https://www. Health impact assessments (HIAs) were used to consider potential health impacts of proposed projects and programs and identify disproportionately affected populations as well as how to mitigate adverse effects9,11,12 HIAs improved collaboration, amplified community member voices, increased awareness of health issues, and informed decision makers, but the time and resources required to complete HIAs limited their success.12 Cross-disciplinary public health, planning, policy, real estate, architecture, engineering, transportation, and public-private partnership efforts, along with Complete Streets approaches (https://highways.dot.gov/ complete-streets), improved pedestrian infrastructure and safety.

Public risk perception of covid-19 transmission and support for compact development

Abstract

In the last few decades, there has been a definitive shift in public support for compact development – characterized by high densities, more multifamily residential use, and effective public transit. The allure of compact development is because, along with sustainability benefits, it offers multiple lifestyle benefits, such as more significant opportunities for socialization and easy access to amenities. Greater possibilities of frequent and longer interpersonal interactions attract residents to such communities. However, given the recent pandemic, it is logical to be concerned about how future public support for compact development may change. This study analyzes data from a national online survey (n = 1100) conducted in the United States toward the end of the COVID-19 pandemic (April 2022). This research aims to assess the relationship between perceived concern for COVID-19 transmission and public support for compact development. The results from SEM analysis suggest that people more concerned about COVID-19 transmission are less supportive of compact development policies. People from areas with higher density and more COVID-19 cases are likely to have greater concern for COVID-19 transmission, which may decrease support for compact development in these areas (mediated relationship). Individuals who rely on news, online media, friends or family for COVID-19 information and single-family residents are also less likely to support compact development. In contrast, while older adults are likely to have higher concern for COVID-19 transmission, they are likely to support compact development. Higher-income households are less likely to be concerned about COVID-19 transmission but are more supportive of compact development. These findings suggest that the perceived threat of disease transmission will likely result in decreased public support for compact development. To ensure continued public support, urban policymakers must allay public fear of virus transmission in compact built environments by incorporating public health measures for controlling virus transmission in compact urban environments.

Applying implementation science to evaluate participatory ergonomics program for continuous improvement: A case study in the construction industry

Abstract

While participatory ergonomics (PE) presents numerous benefits, its empirical effectiveness remains elusive due to the lack of transparency in implementation contexts and processes. This hinders our ability to discern the reasons behind a program's success or failure and to determine optimization and adaptation strategies. To unravel this "black box," we present a case study using implementation science to evaluate a PE program and illuminate the mechanisms linking process to outcome. The study examines a 4.5-year PE program at a construction company, targeting musculoskeletal disorders (MSDs) from material-cart handling. Using the RE-AIM framework and Implementation Causal Pathway Model, we evaluated implementation process and catalogued contextual factors through worker surveys (n = 106), safety document review (27 training sessions and 7 construction projects), and key informant observations. We assessed the program's impact using a 42-worker survey and an analysis of 8-year injury data, and determined the return-on-investment (ROI) by monetizing the collected data. The program achieved significant impact: Workers' ergonomic knowledge improved from 73% in baseline to 86% in follow-up; 97% of workers reported at least one positive change in their crews; and no cart handling injuries occurred after the first program change, resulting in a ROI rate of 1.99. Implementation process evaluation revealed that seamless integration, tailored intervention, and ongoing adjustments contributed to the success. Five organizational factors necessary for the effective functioning of these three strategies were identified, along with three moderators that amplified their influence. Finally, this case study demonstrates that implementation science offers a coherent structure for evaluating PE programs, uncovering mechanisms of change, and informing future improvements and adaptations. Our research facilitates knowledge transfer from implementation science to ergonomics, eventually leading to more cost-effective PE programs that are faithfully implemented across various industrial settings to prevent MSDs.
• This case study employs implementation science to assess a participatory ergonomics program within the construction industry.
• The evaluation encompasses the implementation process and context, program outcomes, and the return on investment.

Abstract

While previous studies have established correlations between rooftop solar adoption and various factors, a comprehensive understanding of the underlying causal mechanisms has been limited by the intricate interrelationships among these variables. To address this gap, we propose a Bayesian causal inference approach that examines the interplay of various factors influencing rooftop solar adoption across multiple cities. By employing post-phenomenology, we uncover latent variables encompassing place, people, and process, shedding light on how they shape public responses to emerging energy technologies. We analyze the causal effects of these factors and highlight the significance of housing and built environment attributes in determining energy expenditure and rooftop solar adoption, emphasizing the need for policies that target energy equity. Additionally, we reveal the influence of neighborhood spillovers on adoption, indicating the role of social norms and information diffusion. The observed city-level variability underscores the importance of local contexts and location-specific factors in the adoption process. Furthermore, we highlight the need to consider causal relationships and the indirect effects of people-related attributes mediated through place-related attributes. Overall, these findings contribute to a deeper understanding of the factors shaping rooftop solar adoption via causal modeling and underscore the importance of tailored policies to promote adoption.
