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.
• 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

This book explores the creative potential for architecture curricula to integrate solid interdisciplinary thinking in design studio education.

Annotated case studies, both from academic institutions and from professional practices, provide examples of interdisciplinary engagement in creative design work, highlighting the challenges and opportunities of this approach. Cases are from a diverse selection of international collaborators, featuring projects from the United States, Australia, Mexico, Germany, and Italy, and cover a range of project types and scales. Chapters by invited experts offer speculations on current and future models, situating examples within the broader context, and encouraging dialogue between practice and pedagogy. The collection of voices in this book offers critical and provocative lenses, learning from history while forging inventive and creative roles for the architect as practitioner, entrepreneur, strategist, choreographer, activist, facilitator, leader, and teacher.

Interdisciplinary Design Thinking provides insights into the potential of interdisciplinary engagement at the level of foundational undergraduate education, making it ideal for faculty in architecture schools. It will also be of interest to design professionals concerned with interdisciplinary collaboration and how to incorporate similar efforts in their own practices.

Abstract

Problem, research strategy, and findings
Large language models, such as ChatGPT, have recently risen to prominence in producing human-like conversation and assisting with various tasks, particularly for analyzing high-dimensional textual materials. Because planning researchers and practitioners often need to evaluate planning documents that are long and complex, a first-ever possible question has emerged: Can ChatGPT evaluate plans? In this study we addressed this question by leveraging ChatGPT to evaluate the quality of plans and compare the results with those conducted by human coders. Through the evaluation of 10 climate change plans, we discovered that ChatGPT’s evaluation results coincided reasonably well (with an average of 68%) with those from the traditional content analysis approach. We further scrutinized the differences by conducting a more in-depth analysis of the results from ChatGPT and manual evaluation to uncover what might have contributed to the variance in results. Our findings indicate that ChatGPT struggled to comprehend planning-specific jargon, yet it could reduce human errors by capturing details in complex planning documents. Finally, we provide insights into leveraging this cutting-edge technology in future planning research and practice.
Takeaway for practice
ChatGPT cannot be used to replace humans in plan quality evaluation yet. However, it is an effective tool to complement human coders to minimize human errors by identifying discrepancies and fact-checking machine-generated responses. ChatGPT generally cannot understand planning jargon, so planners wanting to use this tool should use extra caution when planning terminologies are present in their prompts. Creating effective prompts for ChatGPT is an iterative process that requires specific instructions.

Color as metaphor in architectural design

Abstract

In the early stage of a building design, forming a design concept is the first step. The architect must assimilate and organize information involving spatial needs, engineering, building codes, and budget considerations. They must also consider its visual appearance, how the building fits into its physical context, and, most importantly, how to conceive of the building holistically as both functional and aesthetic. A process for accomplishing this will use a methodology associated with intuition and imagination. A metaphor is used that gives form to the building through an analogy that imitates its activities and function and serves as a device for conceiving of the building as a whole. Making a design diagram that defines the concept using the metaphor and showing the relationship of the critical parts of the building is the biggest challenge in this stage. A new approach is to assign color to these parts in the design diagram. With the metaphor as guide, the hierarchical status of the parts will be shown by the perceptual weight of the colors in juxtaposition to one another by contrasts in hue, value, and chroma. The results show that the addition of color increases the clarity and comprehension of the design concept in the eyes of the designer, in visual presentations to faculty in academic settings, and to clients in the profession. The color decisions latter in the process may differ from those used in the diagram, but these decisions will adhere to the established hierarchies of the building parts as foreground or background colors. This methodology is intended to be a tool for students in architecture as well as professional architects.

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
