Eco-ableism and access circularity in natural building

Frontiers of Architectural Research 2024年第2期13卷 235-248页

作者： Grace Schleck Lola Ben-Alon Barnard College department of Architecture New YorkUSA Columbia University Graduate School of Architecture Planningand Preservation(GSAPP)New YorkUSA

The climate crisis disproportionately impacts disabled people. Yet climate-related advocacy, planning, and policymaking often neglect to thoughtfully include disabled people. Responding to this gap, disabled and neurodivergent environmental activists coined the term eco-ableism to describe discrimination and silencing toward disabled and neurodivergent people (i.e., ableism) arising in environmental spaces (i.e., eco-ableism). Relatedly, building operations and construction practices contribute a significant percentage of global, energy-related CO_(2) emissions annually, which calls into question the relationships between the impending climate crisis, disability justice, and architecture. Climate-specific, natural building materials and methods present a potential pathway toward a more sustainable built future: low-carbon, locally sourced, minimally processed, and nontoxic materials. Despite a critical overlap, there is little published research on material access in the production phase and human access in the occupation phase of natural buildings. Applying eco-ableism and material circularity in an architectural framework, this research aims to investigate the gaps and possibilities of access, natural material applications, and resulting US natural buildings informed by scholarship in critical disability studies and semi-structured interviews with natural building professionals.

Objective To explore the demographic and disease-related factors associated with acupuncture response in patients with chronic tension-type headache(CTTH).Methods Using data from a randomized clinical trial(218 cases)consisting of 4 weeks of baseline assessment,8 weeks of treatment,and 24 weeks of follow-up,participants were regrouped into responders(at least a 50%reduction in monthly headache days at week 16 compared with baseline)and ***-three demographic and disease-related factors associated with acupuncture response in 183 participants were analyzed by multivariable logistic *** One hundred and nineteen(65.0%)participants were classified as *** factors were significantly independently associated with acupuncture response,including treatment assignment,headache intensity at baseline,and 2 domains[general health(GH)and social functioning(SF)]from the 36-Item Short Form Health Survey quality of life *** assignment was associated with non-response:participants receiving true acupuncture were 3-time more likely to achieve a CTTH response than those receiving superficial acupuncture[odds ratio(OR)0.322,95%confidence interval(CI)0.162 to 0.625,P=0.001].Compared with patients with mild-intensity headache,patients with moderate-intensity headache were twice as likely to respond to acupuncture(OR 2.001,95%CI 1.020 to 4.011,P=0.046).The likelihood of non-response increased by 4.5%with each unit increase in the GH grade(OR 0.955,95%CI 0.917 to 0.993,P=0.024)while decreased by 3.8%with each unit increase in the SF grade(OR 1.038,95%CI 1.009 to 1.069,P=0.011).Conclusions Greater headache intensity,lower GH score,and higher SF score were associated with better acupuncture responses in CTTH *** 3 factors require independent validation as predictors of acupuncture effectiveness in CTTH.
