Essays in economic policy and human behavior

This dissertation is composed of three chapters. While the chapters pertain to very different contexts, an overarching theme is the analysis of human behavior in response to policies that are inherently economic.The first chapter is the product of joint work with Justin Holz and Rafael Jimenez Duran. It studies repugnance towards price gouging. Emergencies like natural disasters or pandemics trigger sharp price increases for essential products. Anti-price gouging laws are ubiquitous and people take costly actions to report violators to law-enforcement agencies, which suggests that they value punishing sellers that spike prices in these situations. This chapter uses a field experiment to understand individuals' willingness to report sellers who increase the price of personal protective equipment at the height of the COVID-19 pandemic. We argue that reporting decisions contain information about repugnance to price gouging and find that willingness to pay to report is non-trivial and heterogeneous. We also find evidence that repugnance is partly due to distaste for seller profits, depending on the product. These results suggest that regulation discussions would benefit from incorporating repugnance into welfare and from addressing products separately.The second chapter focuses in the use of temporary driving restrictions as a tool for air quality management in Mexico City. Road congestion is understood to be a major source of urban air pollution and is also associated with other large non-health-related costs. Millions of people live in cities in which the number of cars on the road is controlled by allowing or prohibiting the use of a car on a given day depending on its license plate number. The empirical evidence available suggests little benefit from these programs;the policy increases the marginal cost of using the road for some users while decreasing it for others and incentivizes the acquisition of extra vehicles. This chapter studies the effect of temporary increases in the stringency of the restrictions as an add-on policy intended to alleviate extreme pollution events. The increased restrictions are triggered by Ozone levels surpassing a pre-specified threshold. This, coupled with the fact that said threshold was modified several times between 2005 and 2018, allows us to identify the effect of the policy. We document a sizable increase in the average speed of cars in the city during restricted days. This suggests the policy does alleviate congestion. We also observe a reduction on Carbon Monoxide and Ozone concentration, but these results are not robust to changes in the specification's functional form. While we cannot explicitly quantify welfare effects, the minor improvements are unlikely to compensate the major disruption in the commuter network without serious investment in public transit alternatives.The third chapter, co-authored with Enrique Seira and Alan Elizondo, investigates the role of information disclosure on financial markets as tool for consumer protection. We implement a randomized control trial in the Mexican credit card market for a large population of indebted cardholders and measure the impact of disclosures of interest rate and time required to pay outstanding debt on default, indebtedness, account closings, and credit scores;these disclosures are required by law in the United States. We also test the effect debiasing warning messages and social comparison information has on the same outcomes. We find that providing salient interest rate disclosures had no effects, while comparisons and debiasing messages had only modest and short-lived effects at best. We conduct extensive external validity exercises in several banks, with different disclosures, and with actual policy mandates. We conclude the null result is robust.

Planning cities for pandemics: A review of urban and transport planning lessons from COVID-19

For the past years, the world has been facing one of the worst pandemics of modern times. The COVID-19 outbreak joined a long list of infectious diseases that turned pandemic, and it will most likely leave scars and change how we live, plan, and manage the urban space and its infrastructures. Many fields of science were called into action to mitigate the impacts of this pandemic, including spatial and transport planning. Given the large number of articles recently published in these research areas, it is time to carry out an overview of the knowledge produced, synthesising, systematising, and critically analysing it. This article aims to review how the urban layout, accessibility and mobility influence the spread of a virus in an urban environment and what solutions exist or have been proposed to create a more effective and less intrusive response to pandemics. This review is split into two avenues of research: spatial planning and transport planning, including the direct and indirect impact on the environment and sustainability. © 2023 ICE Publishing: All rights reserved.

The spatial concentration, stability, and specialization of mental health calls for service: Evidence in support of proactive, place-based interventions

For many decades the police have been the de facto responders to persons with perceived mental illness (PwPMI). However, having the police in this role has come with negative repercussions for PwPMI, such as disproportionately experiencing criminalization and use of force. In recognizing these issues, the police-and more recently, the community-have developed responses that either seek to improve interactions between the police and PwPMI or remove the police from this role altogether. However, in either case, these efforts are reactivein nature, responding to crises that arguably could have been prevented had a timelier intervention taken place. Further, evidence on certain police responses to PwPMI, such as Crisis Intervention Teams (CIT) and co-response teams, suggests that they endure deployment-related challenges, thus limiting their reach to PwPMI.Drawing from the Criminology of Place and existing place-based policing strategies, the present dissertation argues that efforts focused on respondingto PwPMI should instead be proactively deployed, targeting areas where interactions between police and PwPMI concentrate spatially. Doing so would not only result in efficient deployment of scarce resources but would permit police- and community-based efforts to have a greater reach to PwPMI and thus prevent future interactions with police. To-date, however, there have been few empirical and theoretical investigations into the spatial patterns of PwPMI calls for service that could inform such proactive, place-based efforts. Specifically, we do not currently understand: (1) the degree to which PwPMI calls for service concentrate within certain geographical contexts (such as a small city);(2) whether the degree of PwPMI call concentration and the location of these calls remain stable over time;and (3) what theoretical frameworks explain why PwPMI calls for service occur where they do. Drawing on seven years (2014-2020) of calls for service data from the Barrie Police Service and data from the 2016 Canadian Census, the present dissertation employs various methods of spatial analysis to fills these specific knowledge gaps.Although the theoretical investigation confirmed the findings of previous work that found no association between social disorganization theory and the spatial patterns of PwPMI calls for service, the present dissertation revealed: (1) PwPMI calls for service are highly concentrated within the context of a small city, even more so than what has previously been uncovered in larger jurisdictions;(2) the degree of PwPMI call concentration is stable over time, falling within a narrow proportional bandwidth of spatial units;and (3) PwPMI calls for service, and their concentrations, occur in the same places over time-even during the COVID-19 pandemic-and are thus spatially stable. As such, though more scholarship is needed on theories that might help explain why PwPMI calls occur where they do, the findings of the present dissertation strongly support the proactive, place-based deployment of resources to PwPMI.

Development of a core outcome set for studies investigating safety, efficacy, and implementation of COVID-19 vaccines: A collaboration with African American/Black communities in Baltimore City, Maryland

Background: Since it was declared a global pandemic in March 2020, Coronavirus Disease 2019 (COVID-19) has claimed over one million lives in the United States. Since COVID-19 vaccine rollout efforts began in Baltimore City, Maryland in December 2020, approximately 63.4% of all residents have been fully vaccinated (i.e., received their first and second doses in a two-dose series or received a single-dose vaccine). Despite efforts to implement equitable vaccine distribution in Baltimore City, prominent disparities in COVID-19 vaccine uptake persist, with poorer, predominantly Black neighborhoods frequently reporting lower levels of vaccine uptake than affluent, predominantly White neighborhoods. Guided by key principles of community-based participatory research, this dissertation explores community experiences with COVID-19 vaccines and develops a core outcome set (COS), inclusive of community-important outcomes, for use in studies evaluating the safety, efficacy, and implementation of COVID-19 vaccines. Methods: In March 2022, semi-structured interviews were held with vaccinated and unvaccinated Black residents of a community in Baltimore City reporting 40% vaccination uptake. Data were analyzed using inductive thematic analysis with subsequent subgroup analyses and thematic network analyses. To assess the extent to which outcomes measured in COVID-19 vaccine studies published between December 2019 and March 2022 aligned with factors of vaccine hesitancy, a systematic literature review (SLR) was conducted. Results from the qualitative analyses and the SLR informed the development of a candidate list of outcomes used in the first round of a Delphi study held in June 2020. After two rounds of Delphi survey distribution, a face-to-face consensus meeting was held with community members and community health workers to prioritize outcomes of interest to all relevant stakeholders and finalize the COS. Results: Thematic analysis yielded four emergent themes relating to COVID-19 vaccine uptake decision making: (I) Safety and efficacy of vaccines, (II) Perceived importance of COVID-19 vaccines in relation to pre-existing community needs, divided into two subthemes, a) Environmental injustice and (b) Personal health concerns, (III) Access to trustworthy, understandable information, and (IV) Physical access to vaccines. Participants acknowledged that physical access to COVID-19 vaccines was not a major barrier to uptake, however finding trustworthy and understandable information about the safety and efficacy of the vaccines were common areas of concern. Of all primary outcomes (N=20) identified in the 56 articles included in the SLR, 85% (n=17) corresponded with factors of vaccine hesitancy. The final COS included 19 outcomes across four "domains:" "Is the vaccine safe?";"Does the vaccine work in my body?";"Does the vaccine work in the community?";and "Outcomes identified during consensus meeting." Conclusion: The findings from this dissertation suggest that although community-important outcomes related to safety and efficacy of vaccines are often addressed in clinical studies, outcomes measuring institutional trust, economic and health impacts, community acceptance of the vaccines, and trustworthiness of vaccine information are underutilized in studies of vaccine implementation. As these social factors function as barriers to vaccine uptake, particularly among underserved communities, they should be regarded as indicators of equitable access to COVID-19 vaccines. The findings from this dissertation provide a framework with which public health researchers can begin to rethink measures of equity in vaccine rollout efforts.

Envisioning innovative post-COVID approaches toward LTCF design in dense urban areas: Exploring an evidence-based design prototype

The COVID-19 (coronavirus disease 2019) pandemic has posed greater challenges to older adults, especially those who live in congregated long-term care facilities (LTCFs) in dense urban settings. These facilities struggle with high rates of COVID-19 infections and other challenges that undermine LTCF residents' well-being. These challenges, including social isolation and limited access to nature and community, have been exacerbated by the pressures of the pandemic. This has led to feelings of loneliness, depression, and other mental health issues among residents and a higher risk of psychological stress and infection among nurses. The pandemic has challenged the existing built environment of LTCFs. Issues regarding physical and mental health, quality of life (QoL), infection control, and pandemic resiliency have been shown to be increasingly interwoven. This chapter envisions innovative approaches toward a post-COVID-19 environment for older adults and their caregivers. This chapter provides an extensive review and synthesis of the lessons learned from LTCFs during the pandemic, with a focus on how their experience was impacted by design. The authors also draw from current design trends to identify their potential to support residents', staff, and visitors' needs during and after pandemics. From these learnings, the following design principles were developed: (1) small household model, (2) biophilic design, (3) intergenerational community, and (4) multi-tier infection control strategies. These design principles were then translated to a prototype through a graduate capstone studio project, which provides a visual illustration of how these evidence-based design solutions can be applied within a dense urban environment.

Reaching city youth with an online summer arts workshop in Los Angeles

The Summer Arts Workshop (SAW) is a community-based art therapy program with a social justice focus. It has been offered through the Helen B. Landgarten (HBL) Art Therapy Clinic at Loyola Marymount University (LMU) since 2007 in partnership with Dolores Mission School in Boyle Heights, a historically under-resourced part of East Los Angeles. In 2020, due to the COVID-19 pandemic and stay-at-home orders in Los Angeles, the SAW leadership team adapted the workshop to an online format. The authors took advantage of the online format to extend the reach of the workshop to several school sites in marginalized communities in Los Angeles County, including a juvenile hall high school, which is a prison for youth in a state youth detention centre. The greatest challenge in adapting to an online format was preserving the core component of the workshop: building trust and healthy attachments through expressive art making. The authors overcame this and other challenges and succeeded in providing connecting experiences for participants and facilitators during a time of social isolation and collective anxiety. This chapter shows how teletherapy can bridge gaps of access, particularly for marginalized populations. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Geographic Information Systems for Facilitating Audits of the Urban Built Environment

Data collection and large-scale urban audits are challenging and can be time consuming processes. Geographic information systems can extract and combine relevant data that can be used as input to calculation tools that provide results and quantify indicators with sufficient spatial analysis to facilitate the local decision-making process for building renovations and sustainability assessment. This work presents an open-access tool that offers an automated process that can be used to audit an urban area in order to extract relevant information about the characteristics of the built environment, analyze the building characteristics to evaluate energy performance, assess the potential for the installation of photovoltaics on available building rooftops, and quantify ground permeability. A case study is also presented to demonstrate data collection and processing for an urban city block, and the relevant results are elaborated upon. The method is easily replicable and is based on open data and non-commercial tools.

Heat vs. Health: Home Office under a Changing Climate

Stressors are especially widespread in urban agglomerations. Common themes of built environment interventions that support health and well-being are blue and green infrastructure, indoor and outdoor air quality, thermal comfort, access to natural lighting, and acoustics. Given the current megatrends of increasing summer temperatures and the high popularity of home offices, we aimed at modeling thermal comfort changes of people working at home in three Austrian cities (Vienna, Innsbruck, and Graz) during the next decades until 2090. We present findings based on (I) an inter-disciplinary literature search and (II) indoor and outdoor climate simulations for actual and future climate scenarios. Based on the results, we discuss the potential impacts for work and human health and well-being, and we suggest a framework for the home office in "post-COVID-19 Austria” that integrates social, ecological, and economic aspects. The results of our study indicate that, in future climate scenarios, overheating of the interior can no longer be prevented without active cooling measures and nature-based solutions. Recommendations on the adjustment of behavior under climate change, including greening, adequate ventilation, and cooling techniques, are thus urgently needed for employees who are working from home in order to maintain physical and mental health and wellbeing.

Editorial Introduction

1. Overview of 2nd International Conference on Science in Engineering and Technology - 22nd Sustainable Environment and Architecture (ICoSiET SENVAR 2022)The covid-19 pandemic caused a great shock to people around the world, for it caused a massive scale lockdown in the 21st century. It took millions of lives, affected people's health [1], and created enormous disruption in education systems in more than 200 countries [2]. Furthermore, Covid-19 also account for unprecedented damage to the global economy[3][4], separating people from their loved ones and friends and transforming our built environment in fear of infection[5]. The use of spaces in our living environment then changes dramatically. The lesson should be drawn from this pandemic, for it can never be predicted when the next one will arrive [6]. A future design of the built environment shall be arranged comprehensively. Not only do we have to consider the socio-economic and sustainable living environment, but also how to create a resilient and healthy built environment. Thus, the impact of the pandemic can be minimised through planning, design, structural, physical and technological means.On the other hand, the pandemic introduces a hybrid life to us where a virtual world has become a necessity. Tantalising global challenges in our degradation environment with energy and natural resources depletion force us to have an energy-conscious awareness while providing a safe, healthy, smart and sustainable living environment. The design of the built environment thus should elaborate the virtual world and reality, which involves advanced and robust information and technology not only for the present situation but also for visionary looking to future needs. Therefore, we promote "the Green-Smart Design and Technology for the Present and the Future Built Environment” as the theme for the 2nd International Conference on Science in Engineering and Technology – 22nd Sustainable Environment and Architecture (ICoSiET SENVAR 2022).The ICoSiET SENVAR 2022 is a joint conference to bridge the role of architecture, engineering, and multi-disciplinary field stakeholders in sharing their precious ideas, theories, concepts, designs, research and experiences in creating a better world for all. This conference is hosted by the Architecture Department of Engineering Faculty, Tadulako University. ICoSiET was first organised in 2020 in Palu, Indonesia and then became a biannual conference to provide an academic forum, especially in engineering.Meanwhile, SENVAR is an annual gathering for scientists, scholars, and architects focusing on discussions related to the natural and built environment, such as building design and architecture, outdoor and indoor comfort, local and global green, urban planning and sustainability. SENVAR was first initiated and started by the late Professor Mas Santosa from the Department of Architecture, Institut Teknologi Sepuluh Nopember (ITS) in 2000 as a seminar on environmental architecture;in 2011, it changed the name to Sustainable Environment and Architecture [7]. This year we have the privilege to host ICoSiET and SENVAR and combine them into ICoSiET SENVAR 2022, putting two communities in one frame to be blended in the most recent issue of the smart and sustainable built environment.

The COVID-19 pandemic and urban density: a systematic literature review

The role of density in the spread of the coronavirus pandemic is among the most critical concerns of urban designers and planners. To clarify this role, this systematic literature review is conducted on urban density and the COVID-19 infection and mortality rates in the context of urban design and planning. The studies were searched through three databases including Scopus, PubMed, and Web of Science in March 2022 and were screened and reviewed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In total, 58 of the 3344 studies had pre-defined criteria. The results were categorised into four sections: population density, building density, built environment factors, and sociodemographic factors. Finally, directions are provided for future studies due to research gaps.

Measures of Greenspace Exposure and Their Association to Health-Related Outcomes for the Periods before and during the 2020 Lockdown: A Cross-Sectional Study in the West of England

Greenspaces are argued to be one of the important features in the urban environment that impact the health of the population. Previous research suggested either positive, negative, or no associations between greenspaces and health-related outcomes. This paper takes a step backward to, first, explore different quantitative spatial measures of evaluating greenspace exposure, before attempting to investigate the relationship between those measures and health-related outcomes. The study uses self-reported health data from an online cross-sectional survey conducted for residents in the West of England. This yielded data of greenspace use, physical activity, wellbeing (ICECAP-A score), and connectedness to nature for 617 participants, divided into two sets: health outcomes for the period before versus during the 2020 lockdown. The study uses the participants' postcodes (provided in the survey) to calculate eleven spatial measures of greenspace exposure using the software ArcGIS Pro 2.9.5. A total of 88 multivariate regression models were run while controlling for eleven confounders of the participants' characteristics. Results inferred 57 significant associations such that six spatial measures of greenspace exposure (NDVI R200m, NDVI R300m, NDVI R500m, Network Distance to nearest greenspace access, Euclidean Distance to nearest greenspace access, and Euclidean Distance to nearest 0.5 ha doorstep greenspace access) have significant association to at least one of the four health-related outcomes, suggesting a positive impact on population health when living in greener areas or being closer to greenspaces. Moreover, there are further significant associations between the frequency of use of greenspaces and increasing physical activity or feeling more connected to nature. Still, the residents' patterns of using greenspaces significantly changed during versus before lockdown and has impacted the relationships between health outcomes and the greenspace exposure measures.

Do Residents Living in Transit-Oriented Development Station Catchment Areas Travel More Sustainably? The Impacts of Life Events

Transit-oriented development (TOD) is an urban designed model aimed at attracting more sustainable travellers. However, not all TOD projects succeed in maintaining a high rate of sustainable travel behaviour. To examine the impacts of TOD on residents' travel behaviour, this paper applies binary logistic regression to analyse survey data for 1,298 residents living in the TOD areas in Hangzhou collected in 2020. The results show that socioeconomic characteristics, built environment factors, and travel attitudes play important roles in influencing their travel mode choices. Furthermore, the number of children in households and higher levels of car ownership significantly influence residents' sustainable travel behaviours. However, it appears that only a limited number of factors can convince car users to shift to sustainable modes of travel, such as their workplace being accessible by metro and attitudes towards changes in accessibility. This research study contributes to the existing literature in terms of enhancing the understanding of travel mode choice behaviours, particularly with regard to people who live near public transport infrastructure, as well as formulating evidence-based TOD policies to achieve more sustainable transport systems.

Urban Transportation Concept and Sustainable Urban Mobility in Smart Cities: A Review

In order to create a sustainable future for the urban environment in s=Smart cities, it is necessary to develop a concept of urban transport, partially reduce the use of traditional transport, primarily cars, as well as the environmental pressure on society, which is essential to move to a sustainable urban future. In the latest discussions on the future of the urban transport system, the quality of the environment, and the possibility of its improvement are discussed, this issue became especially relevant with the onset of the pandemic, when the lockdowns were introduced. The problem of sustainable transport in urban areas has been recognized in academic studies, searching for appropriate models and solutions. The article presents the latest literature review and illustrates the newest trends with several examples. VOS Viewer software has been used to classify the different keywords, according to their co-citation, following clustering techniques. By analyzing the research conducted by other researchers, it has been possible to structure the ecosystem and trends in the Urban Transportation Concept, also mentioning likely future trends. Based on the literature analysis of the Sustainable Urban Transport, the authors of the study found that a large group of researchers deal with technical solutions and innovative business models, while the essential behavioral aspects are examined in less detail. Extensive literature analysis allowed the authors to select several solutions to achieve the transformation towards sustainable transportation in urban areas: new vehicle technologies and their environmental factors' analysis, geographic information systems, the analytic hierarchy process method, the time series analysis of road traffic accidents using multiplicative models, electrification and use of Friedman Analysis of Variance by Ranks, as well as innovations in sharing mobility.

Research and evidence-based standards paving the way for a digital and sustainable transformation of the built environment

PurposeResearchers and standardisation bodies are key to accelerating societal transition and contributing to society's demands for sustainability, resilience and digitalisation. Standards are the agreed-upon best practices published by national or international bodies and are key enablers of transformation. Scholars have not yet identified a relationship between standards and facilities management (FM) research. The purpose of this paper is to investigate the role of formal standards in FM research.Design/methodology/approachA literature review was conducted to identify journal articles addressing standards and FM. A total of 198 journal articles published from 2010 to 2021 were identified. After screening these articles, 27 journal articles were considered the most relevant for data analysis.FindingsThe findings show that the role of standards in research can be analysed thematically, categorically, textually, methodologically and directionally. Standards are relevant to research by defining terms, creating backgrounds, guiding research, supporting the development of new standards and encouraging more collaboration between research and standardisation. Some studies have shown how standards influence research, but only a few have explored how research influences standards.Research limitations/implicationsThis research provides examples that inspire stronger collaboration between people and processes in research and standardisation.Originality/valueThe articles collected and analysed in this study comprise original research. A limited preliminary study of ten core articles was presented at the International Council for Research and Innovation in Building and Construction World Congress 2022. This presentation of this work provides an expanded framework for analysing the roles of standards in research. This framework includes (1) categorical analysis of research and standardisation streams;(2) thematic analysis of the topic of interest;(3) textual analysis of the use of the term "standard”;(4) methodological analysis of the influence of standards on the research method;and (5) directional analysis of the intended audience.

Implementing social emotional learning through the use of virtual reality

The integration of Social Emotional Learning into the secondary curriculum is recognized globally as an important set of skills to have, especially since the onslaught of the COVID-19 pandemic. The purpose of combining these skills within a virtual reality program is to engage and enhance the experience the students have learning the new skills. This qualitative exploratory case study was established to determine if the WISE SEL VR program could be easily incorporated into the secondary curriculum in an urban high school. In addition, the secondary purpose was to establish the ease of which virtual reality gave to the instruction of social emotional skills. The findings of the study show that the participants and administrators at an urban high school understand the importance of teaching social emotional learning skills. They also acknowledge that the use of virtual reality enhanced the learning experience for their students. Students were engaged and excited to use the new technology to learn. However, the majority of the participants failed to make the connection between teaching the WISE SEL VR program in their specific content area. The majority of the participants believe the program itself is exceptional but should be a stand-alone course offered as an elective. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Sustainable digitalisation and implementation of ISO standards for facilities management

PurposeThis viewpoint paper aims to discuss sustainable digitalisation of facilities management (FM) through the implementation of the newly recognised International Organization for Standardization (ISO) standards within the ISO 41000 series.Design/methodology/approachThis viewpoint paper provides a review of the literature of the recent ISO documents and academic study. The content is also dependent on the authors' opinions and interpretation.FindingsFM is currently shifting emphasis towards a strategic focus through the adoption of the new recognised international ISO standards that consider sustainable digitalisation in business decisions. However, the FM sector is encountering potential risks to the implementation of the new recognised international ISO standards. Digitalisation is one kind of force that has shaped the management of the built environment and FM recently and rapidly, especially in the Covid-19 period. This is impacting the FM industry. As standardisation aims at establishing a constantly evolving baseline of proven practices, standardisation can be considered a part of sustainable FM. It is believed that standardised and strategic level support is crucial for the smooth adoption of sustainable FM practices and processes. Standards such as the ISO standards, applied to the global FM industry, help in objectively quantifying the added value of FM to the core business. Advanced technology and digitalisation can contribute to the sustainability of any profession and industry, but it also requires a community to tackle the problems.Originality/valueThis paper contributes to the FM industry by making recommendations for improvement in the use of digitalisation. In summary, the significant finding of this viewpoint paper is that digitalisation offers both possibilities and problems in the application of the new recognised international ISO standards within the FM industry.

Managing Building Water Disruptions in a Post-COVID World: Water Quality and Safety Risk Assessment Tool for Academic Institutions and School Settings

Fluctuating building occupancy during the COVID-19 pandemic contributed to poor water quality and safety conditions in building water distribution systems (BWDSs). Natural disasters, man-made events, or academic institutional calendars (i.e., semesters or holiday breaks) can disrupt building occupant water usage, which typically increases water age within a BWDS. High water age, in turn, is known to propagate poor water quality and safety conditions, which potentially exposes building occupants to waterborne pathogens (e.g., Legionella) associated with respiratory disease or hazardous chemicals (e.g., lead). Other influencing factors are green building design and municipal water supply changes. Regardless of the cause, an increasing number of water management policies require building owners to improve building water management practices. The present study developed a Water Quality and Safety Risk Assessment (WQSRA) tool to address gaps in building water management for academic institutions and school settings. The tool is intended to assist with future implementation of water management programs as the result of pending policies for the built environment. The WQSRA was modeled after water management practices created for controlling water contaminants in healthcare facilities. Yet, a novel WQSRA tool was adapted specifically for educational settings to allow building owners to evaluate risk from water hazards to determine an appropriate level of risk mitigation measures for implementation. An exemplar WQSRA tool is presented for safety, facility, industrial hygiene, and allied professionals to address current gaps in building water management programs. Academic institutions and school settings should examine the WQSRA tool and formulate an organization-specific policy to determine implementation before, during, and after building water-disruptive events associated with natural or man-made disasters.

Understanding nonlinear and synergistic effects of the built environment on urban vibrancy in metro station areas

Transit-oriented development (TOD) has long been recognized as a significant model for prospering urban vibrancy. However, most studies on TOD and urban vibrancy do not consider temporal differences or the nonlinear effects involved. This study applies the gradient boosting decision tree (GBDT) model to metro station areas in Wuhan to explore the nonlinear and synergistic effects of the built-environment features on urban vibrancy during different times. The results show that (1) the effects of the built-environment features on the vibrancy around metro stations differ over time;(2) the most critical features affecting vibrancy are leisure facilities, floor area ratio, commercial facilities, and enterprises;(3) there are approximately linear or complex nonlinear relationships between the built-environment features and the vibrancy;and (4) the synergistic effects suggest that multimodal is more effective at leisure-dominated stations, high-density development is more effective at commercial-dominated stations, and mixed development is more effective at employment-oriented stations. The findings suggest improved planning recommendations for the organization of rail transport to improve the vibrancy of metro station areas.

Difficult situations and ways of coping with them in the experiences of parents homeschooling their children during the COVID-19 pandemic in Poland

The aim of the research project is to present parents' perceptions and experiences related to home education during the coronavirus pandemic, and the ways of coping with difficult situations, taking into account sociodemographic factors. At the end of March and beginning of April this year, a survey was conducted on a group of 278 parents living in Poland - in a large city, small town and in the countryside - and affected by this problem. The findings indicate that a significant group of respondents described the existing situation as difficult, and the responsibilities related to home schooling as being beyond their capabilities. Parents are generally not confident about their competence and solutions they adopt;they express anxiety about the future of their children. Significant differences were observed in the ways of perceiving difficult situations and of coping with them with respect to gender and place of residence. The undertaken research is important because the voices of parents shed light on the problems of Polish education in a crisis situation, and at the same time indicate the direction of necessary changes.

Spatio-temporal dynamics of aerosol distribution in an urban environment recorded in situ by means of a bike based monitoring system

Aerosol pollution in urban areas is highly variable due to numerous single emission sources such as automobiles, industrial and commercial activities as well as domestic heating, but also due to complex building structures redirecting air mass flows, producing leeward and windward turbulences and resuspension effects. In this publication, it is shown that one or even few aerosol monitoring sites are not able to reflect these complex patterns. In summer 2019, aerosol pollution was recorded in high spatial resolution during six night and daytime tours with a mobile sensor platform on a trailer pulled by a bicycle. Particle mass loadings showed a high variability with PM10 values ranging from 1.3 to 221 µg m-3 and PM2.5 values from 0.7 to 69.0 µg m-3. Geostatistics were used to calculate respective models of the spatial distributions of PM2.5 and PM10. The resulting maps depict the variability of aerosol concentrations within the urban space. These spatial distribution models delineate the distributions without cutting out the built-up structures. Elsewise, the overall spatial patterns do not become visible because of being sharply interrupted by those outcuts in the resulting maps. Thus, the spatial maps allow to identify most affected urban areas and are not restricted to the street space. Furthermore, this method provides an insight to potentially affected areas, and thus can be used to develop counter measures. It is evident that the spatial aerosol patterns cannot be directly derived from the main wind direction, but result far more from an interplay between main wind direction, built-up patterns and distribution of pollution sources. Not all pollution sources are directly obvious and more research has to be carried out to explain the micro-scale variations of spatial aerosol distribution patterns. In addition, since aerosol load in the atmosphere is a severe issue for health and well-being of city residents more attention has to be paid to these local inhomogeneities.
