Increasing Spanish fluency in the United States likely shapes ethnoracial group boundaries and inequality. We study a key site for group boundary negotiations—the housing market—where Spanish usage may represent a key source of information exchange between landlords and prospective renters. Specifically, we examine the use of Spanish in advertisements for online rental housing and its effect on White, Black, and Latinx Americans' residential preferences. Using a corpus of millions of Craigslist rental listings, we show that Spanish listings are concentrated in majority-Latinx neighborhoods with greater proportions of immigrant and Spanish-speaking residents. Furthermore, units that are advertised in Spanish tend be lower priced relative to non-Spanish ads in the same neighborhood. We then use a survey experiment to demonstrate that Spanish usage decreases White, Black, and non-Spanish-speaking Latinx Americans' interest in a housing unit and surrounding neighborhood, whereas Spanish-speaking Latinx respondents are less affected. We discuss these findings in light of past work on neighborhood demographic preferences, segregation, and recent theorizing on within-category inequality.

Using a unique data set of millions of advertisements for rental housing and data on the geographic distribution of housing voucher holders, we examine the limits of housing market policies that rely on private-market landlords to meet public needs. We find that although advertised affordable housing is more prevalent in some zip codes than others, voucher households are more geographically clustered than affordable housing. Moreover, voucher holders are overly concentrated in “lower opportunity” zip codes, those with fewer resources for children’s well-being, despite the advertisement of affordable housing in higher opportunity neighborhoods. Using text-analysis techniques, we identify advertisements that explicitly accept or reject voucher holders and find that ads seeking voucher-holding tenants are overrepresented in lower opportunity neighborhoods. We evaluate the significance of these findings for theories of predatory inclusion.

Introduction: The upscale of surgical service delivery in low to middle income countries will increase health sector greenhouse gas emissions globally. Understanding surgical greenhouse gas emissions from surgical suite activities can direct decarbonization strategies and achieve local, and global climate change objectives. Material and methods: A prospective surgical suite carbon foot print study was conducted at the Alotau Provincial Hospital from the 28th March 2022 to the 28th of May 2022. Results: The total carbon emission for the surgical suite in APH over the study period was 2,665.8 kgCO2e. The average carbon emission per surgical case within the boundary of the surgical suite was 8.4 kgCO2e. Scope one emissions (anaesthetic gases) accounted for 44.7% (1171.3 kgCO2e) of all carbon emissions. Conclusion: If no action is taken, carbon emissions in the western pacific region will continue to increase from surgical suites. Therefore, proactive efforts to reduce greenhouse gas emissions must be prioritized.
