A Pilot Study of Sidewalk Equity in Seattle Using Crowdsourced Sidewalk Assessment Data

We examine the potential of using large-scale open crowdsourced sidewalk data from Project Sidewalk to study the distribution and condition of sidewalks in Seattle, WA. While potentially noisier than professionally gathered sidewalk datasets, crowdsourced data enables large, cross-regional studies that would be otherwise expensive and difficult to manage. As an initial case study, we examine spatial patterns of sidewalk quality in Seattle and their relationship to racial diversity, income level, built density, and transit modes. We close with a reflection on our approach, key limitations, and opportunities for future work.Comment: Workshop paper presented at "The 1st ASSETS'22 Workshop on The Future or urban Accessibility (UrbanAccess'22)

Beyond Exposure to Outdoor Nature: Exploration of the Benefits of a Green Building’s Indoor Environment on Wellbeing

Most research exploring the psychological benefits of the natural environment has focused on direct exposure to the outdoors. However, people spend most of their time indoors, particularly in office buildings. Poor employee mental health has become one the most prevalent and costly occupational health issues. The integration of high quality environmental features (e.g., access to sunlight) in green-certified office buildings offers a superior work environment. These nature-based experiences are anticipated to provide beneficial outcomes to wellbeing. This study is the first to empirically investigate these benefits. Participants in a green (LEED gold certified) office building (N = 213) in Canada completed an assessment of environmental features, measures of hedonic, eudaimonic and negative wellbeing (NWB) and assessments of psycho-environmental potential, environmental behaviors and social belonging. Linear regression analyses confirmed the benefits of indoor environmental features for all aspects of wellbeing. Multiple regression analyses were conducted to assess the effect of specific indoor environmental features on wellbeing. We explored physical features (e.g., air quality, light), and social features (e.g., privacy), as well as windows to the outside. Results suggest that physical features are important in promoting hedonic wellbeing, while social features prevent NWB. Both features equally predicted eudaimonic wellbeing (EWB). A view to the outside was positively correlated to wellbeing, although it did not uniquely predict it after accounting for other environmental features. Path analyses revealed the importance of person-environment fit, pro-environmental behavior and social belonging in mediating the association of indoor environmental features with hedonic and EWB. The results suggests that, by fostering person-environment fit, pro-environmental behaviors and feeling of community in a high quality setting, green buildings may lead to benefits on an array of wellbeing dimensions. The theoretical and practical implications of these findings are discussed

Exploring the facilitators and barriers to shopping mall use by persons with disabilities and strategies for improvements: Perspectives from persons with disabilities, rehabilitation professionals and shopkeepers

AbstractPersons with disabilities face challenges which impact on their ability to accomplish daily activities such as moving around, communicating and fulfilling social roles. Social participation assumes individuals with disabilities live within their community and interact with others. Shopping malls are public spaces used by individuals for various reasons. Here, all components of the social and physical environment interact and have an impact on social participation. This exploratory and qualitative study provides a multi-perspective assessment of the usability, as well as of the environmental facilitators and obstacles to social participation in shopping malls. The results also suggest necessary improvements. We interviewed 15 persons with disabilities, 15 rehabilitation professionals and 9 shopkeepers. Participants viewed the mall as a multifunctional place for everyday use, but at times, also as a limiting place. Multiple facilitators and obstacles were identified; the most important were interaction with shopkeepers and the mall's design for mobility or wayfinding. All participants agreed shopkeeper training and an improved awareness of the needs of persons with disabilities would be beneficial. Multiple stakeholders’ perceptions provide a basis for further investigation about needed changes and their potential for making malls more welcoming and inclusive to all

Ultra-deep Spitzer Mid-Infrared Spectroscopy of LIRGs and ULIRGs at z ~ 1-2

We present ultra-deep mid-IR spectra of 48 infrared-luminous galaxies in the GOODS-South field obtained with the InfraRed Spectrograph (IRS) on the Spitzer Space Telescope. These galaxies are selected among faint infrared sources (0.14 - 0.5 mJy at 24 um) in two redshift bins (0.76-1.05 and 1.75-2.4) to sample the major contributors to the cosmic infrared background at the most active epochs. We estimate redshifts for 92% of the sample using PAH and Si absorption features. Only few of these galaxies (5% at z~1 and 12% at z~2) have their total infrared luminosity dominated by emission from AGN. The averaged mid-IR spectra of the z~1 LIRGs and of the z~2 ULIRGs are very similar to the averaged spectrum of local starbursts and HII-like ULIRGs, respectively. We find that 6.2um PAH equivalent widths reach a plateau of ~1 um for L(24 mu) < 1E11 L(sun). At higher luminosities, EW (6.2 mu) anti-correlates with L(24 um). Intriguingly, high-z ULIRGs and SMG lie above the local EW (6.2 um) - L(24 um) relationship suggesting that, at a given luminosity, high-z ULIRGs have AGN contributions to their dust emission lower than those of local counterparts. A quantitative analysis of their morphology shows that most of the luminous IR galaxies have morphologies similar to those of IR-quiet galaxies at the same redshift. All z~2 ULIRGs of our sample are IR-excess BzK galaxies and most of them have L(FIR)/L(1600A) ratios higher than those of starburst galaxies at a given UV slope. The ``IR excess'' (Daddi et al. 2007) is mostly due to strong 7.7 um PAH emission and under-estimation of UV dust extinction. On the basis of the AGN-powered L (6 um) continuum measured directly from the mid-IR spectra, we estimate an average intrinsic X-ray AGN luminosity of L(2-10 keV) = (0.1 +/- 0.6) 1E43 erg/s, a value substantially lower than the prediction by Daddi et al. (2007).Comment: 45 pages, 36 figures, 2 tables, accepted for publication on Ap

A MIXED-METHODS STUDY ON PROSTHESIS USE AMONG OLDER CANADIANS WITH LOWER-LIMB AMPUTATIONS

BACKGROUND: The prevalence of lower-limb amputations (LLA) in older adults is increasing. Due to the substantial resources required for rehabilitation, there is growing interest in exploring prosthesis use as well as the factors that impact use for individuals with LLA. OBJECTIVES: To examine how older adults, those over 50 years old, with a new LLA use their prostheses following rehabilitation and to identify factors that increase or decrease prosthesis use after discharge from a rehabilitation hospital. METHODS: The StepWatch Activity Monitor, the Prosthetic Profile of the Amputee Questionnaire, and a semi-structured interview were used to measure prosthesis use and factors affecting use at 12 weeks post-discharge from a rehabilitation hospital. Descriptive statistics were calculated for the quantitative data and the qualitative interviews were analyzed using the International Classification of Functioning and Disability. RESULTS: Two user profiles emerged from the 11 participants’ use patterns. The Regular Users integrated their prosthesis into their lives, using it for various types of activities, while the Strategic Users wore their prosthesis to perform specific activities of daily and instrumental activities of daily living tasks. Body functions (e.g., pain), personal (e.g., feeling of independence), and environmental factors (e.g., home adaptations or social support) impacted prosthesis use. CONCLUSIONS: The emergence of profiles suggests variability in how older adults with LLA use their prosthesis after rehabilitation. However, the factors affecting prosthesis use were similar between the profiles. Therefore, while it is important for rehabilitation teams to consider patients’ individual needs when setting goals for prosthetic training, they must also consider common factors affecting prosthesis use. Layman's Abstract The prevalence of lower-limb amputations (LLA) in older adults is increasing. Because of the substantial resources rehabilitation demands, there is growing interest in exploring prosthesis use as well as the factors that impact use for individuals with LLA. In this study we examine how adults over the age of 50 with LLA use their prosthesis after rehabilitation. We also identify factors that increase or decrease prosthesis use after leaving a rehabilitation hospital. We used several measures to study prosthesis use. The StepWatch Activity Monitor, the Prosthetic Profile of the Amputee Questionnaire, and a semi-structured interview were all used to measure prosthesis use after 12 weeks from leaving a rehabilitation hospital. Two user profiles emerged from our data. The Regular Users integrated their prosthesis into their lives, using it for various types of activities, while the Strategic Users wore their prosthesis to perform specific ADL and IADL tasks. Body functions (e.g., pain), personal (e.g., feeling of independence), and environmental factors (e.g., home adaptations or social support) impacted prosthesis use. Our findings suggest there is variability in how older adults with LLA use their prosthesis after rehabilitation. However, the factors affecting prosthesis use were similar between the profiles. Therefore, while it is important for rehabilitation teams to consider patients’ individual needs when setting goals for prosthetic training, they must also consider common factors affecting prosthesis use.

Examining the Impact of Knowledge Mobilization Strategies to Inform Urban Stakeholders on Accessibility: A Mixed-Methods study

Urban areas offer many opportunities for people with disabilities, but limited accessibility may prevent their full engagement in society. It has been recommended that the experience-based perspective of people with disabilities should be an integral part of the discussion on urban accessibility, complementing other stakeholder expertise to facilitate the design of more inclusive environments. The goals of this mixed-method study were to develop knowledge mobilization (KM) strategies to share experience-based findings on accessibility and evaluate their impact for various urban stakeholders. Using a participatory approach, various KM strategies were developed including videos, a photo exhibit and an interactive game. These strategies were evaluated based on various impact indicators such as reach, usefulness, partnerships and practice changes, using quantitative and qualitative methods. The findings suggested that the KM strategies were effective in raising the awareness of various urban stakeholders and providing information and guidance to urban planning practices related to accessibility.Medicine, Faculty ofOther UBCNon UBCOccupational Science and Occupational Therapy, Department ofReviewedFacult

Interaction Between Modern Radiotherapy and Immunotherapy for Metastatic Prostate Cancer

International audienceProstate cancer is the most frequently diagnosed cancer in men and a leading cause of cancer-related death. In recent decades, the development of immunotherapies has resulted in great promise to cure metastatic disease. However, prostate cancer has failed to show any significant response, presumably due to its immunosuppressive microenvironment. There is therefore growing interest in combining immunotherapy with other therapies able to relieve the immunosuppressive microenvironment. Radiation therapy remains the mainstay treatment for prostate cancer patients, is known to exhibit immunomodulatory effects, depending on the dose, and is a potent inducer of immunogenic tumor cell death. Optimal doses of radiotherapy are thus expected to unleash the full potential of immunotherapy, improving primary target destruction with further hope of inducing immune-cell-mediated elimination of metastases at distance from the irradiated site. In this review, we summarize the current knowledge on both the tumor immune microenvironment in prostate cancer and the effects of radiotherapy on it, as well as on the use of immunotherapy. In addition, we discuss the utility to combine immunotherapy and radiotherapy to treat oligometastatic metastatic prostate cancer
