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

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.
• We delve into the mechanisms of change, establishing a link between the process and its intervention outcomes.
• We identify critical implementation strategies, including their preconditions and moderating factors.
• Through the lens of implementation science, we provide a structured framework for evaluating the execution of ergonomic intervention, thereby guiding improvements and future adaptations

Abstract

INTRODUCTION
We examined whether a combined measure of neighborhood greenspace and neighborhood median income was associated with white matter hyperintensity (WMH) and ventricle size changes.

METHODS
The sample included 1260 cognitively normal ≥ 65‐year‐olds with two magnetic resonance images (MRI; ≈ 5 years apart). WMH and ventricular size were graded from 0 (least) to 9 (most) abnormal (worsening = increase of ≥1 grade from initial to follow‐up MRI scans). The four‐category neighborhood greenspace–income measure was based on median neighborhood greenspace and income values at initial MRI. Multivariable logistic regression tested associations between neighborhood greenspace–income and MRI measures (worsening vs. not).

RESULTS
White matter grade worsening was more likely for those in lower greenspace–lower income neighborhoods than higher greenspace–higher income neighborhoods (odds ratio = 1.73; 95% confidence interval = 1.19–2.51).

DISCUSSION
The combination of lower neighborhood income and lower greenspace may be a risk factor for worsening white matter grade on MRI. However, findings need to be replicated in more diverse cohorts.

HIGHLIGHTS
Population‐based cohort of older adults (≥ 65 years) with greenspace and MRI data
Combined measure of neighborhood greenspace and neighborhood income at initial MRI
MRI outcomes included white matter hyperintensities (WMH) and ventricular size
Longitudinal change in MRI outcomes measured approximately 5 years apart
Worsening WMH over time more likely for lower greenspace‐lower income neighborhoods

Abstract

Existing visual comfort metrics are reviewed and critiqued based upon their ability to explain the variability in human subjective responses in a daylit private office laboratory environment. Participants (n = 48) evaluated visual comfort and preference factors, totaling 1488 discreet appraisals, and luminance-based metrics were captured with high dynamic range images and illuminance-based metrics were recorded. Vertical illuminance outperformed all commonly referenced visual comfort metrics including horizontal illuminance, IES luminance ratios, daylight glare probability (DGP), and daylight glare index (DGI). The bounded borderline between comfort and discomfort is introduced, and preliminary visual comfort design criteria are proposed for several existing metrics. Fundamental limitations of glare indices are documented, and the implications of inconsistent application of luminance ratio calculation methods are quantified. Future research is detailed.

Non-ionizing radiation modeling to predict ambient irradiance in work areas at an indoor cannabis farm

Chmielinski, M., Yost, M. G., Cohen, M., Inanici, M., & Simpson, C. D. (2023). Non-ionizing radiation modeling to predict ambient irradiance in work areas at an indoor cannabis farm. Annals of Work Exposures and Health. https://doi.org/10.1093/annweh/wxad048

Abstract

Agricultural workers frequently experience potentially hazardous exposure to non-ionizing radiation from both solar and artificial sources, and measurement of this exposure can be expensive and impractical for large populations. This project develops and evaluates a vegetative radiative transfer model (VRTM) to predict irradiance in a grow room of an indoor cannabis farm. The model uses morphological characteristics of the crop, manufacturer provided lamp emissions data, and dimensional measurements of the grow room and cannabis hedgerows to predict irradiance. A linear regression comparing model predictions with the measurements taken by a visible light spectroradiometer had slopes within 23% of unity and R2 values above 0.88 for visible (400–700 nm), blue (400–500 nm), green (500–600 nm), and red (600–700 nm) wavelength bands. The excellent agreement between the model and the measured irradiance in the cannabis farm grow room supports the potential of using VRTMs to predict irradiance and worker exposure in agricultural settings. Because there is no mechanistic difference between visible and other non-ionizing wavelengths of radiation in regards to mechanisms of radiative transfer, the model developed herein for visible wavelengths of radiation should be generalizable to other radiation bands including infrared and ultraviolet radiation.

Abstract

Standard emergency management practice in the U.S measures disaster preparedness as an individual household attribute based on amounts of stocked supplies, hazard mitigation actions, and emergency planning. Such measures generally fail to consider how norms of trust, fairness, and reciprocity, as well as networks of social relationships—that is, social capital—can facilitate coordination and enable sharing and communal action in the face of disaster. Our study assesses how shared resources, social capital, and day-to-day resources (specifically, food and water) could influence earthquake disaster preparedness across different communities. Using Seattle as the site of investigation, the study involved a split-ballot experiment embedded in a mail survey of a random sample of households. These households were stratified by zip codes selected for their contrasting demographics (N = 1340). Half of the households in each zip code answered conventional individualistic measures of disaster preparedness, while the other half answered questions regarding resources they, their family, friends, and neighbors might share. In racial-majority-dominated zip codes, reported preparedness was higher when people were asked to consider shared resources. Disaster preparedness also appeared to be underestimated with the traditional measure. Households with greater bridging social capital (connections with individuals who differ in their social identity but who may share some similar interests) and longer neighborhood tenure also reported higher preparedness. Our findings suggest disaster preparedness efforts should focus on supplementing individual preparedness with daily resources, social capital, and collective shareable community assets—a focus that we call “mainstreaming.”
