This article aims to reflect on the challenges affecting people experiencing homelessness in Rio de Janeiro, Brazil, due the COVID-19 pandemic. Participatory research was carried out to identify data related to sociodemographic profile; strategies for survival; health and social care support; and access to services during the pandemic. The research methodology was co-designed with NGOs and people with lived experience of homelessness and involved conducting semi-structured questionnaires with 304 participants in 2020. The results highlighted the worsening of the situation of extreme vulnerability and poverty already experienced by this population before the pandemic. Key strategies led by Third Sector organizations to reduce the spread of the virus, to minimize the financial impact of lockdown, and to increase emotional support and information on COVID-19 were presented. The conclusions show the complexity of issues affecting these groups and the need for urgent response from public policies and Government support to guarantee their rights, dignity, and respect during and after the COVID-19 pandemic.

Global food production and availability in hot climate zones are limited by biotic and abiotic factors that affect agricultural production. One of the alternatives for intensifying agriculture and improving food security in these regions is the use of naturally ventilated greenhouses, an alternative that still requires information that allows technical criteria to be established for decision-making. Therefore, the objective of this work was to study the spatial distribution of temperature and relative humidity inside a greenhouse built in the Colombian Caribbean. The methodological approach included the implementation of an experimentally validated 3D numerical simulation model. The main results obtained allowed to determine that the airflows generated inside the greenhouse had average velocities below 0.5 m/s and were mainly driven by the thermal effect of natural ventilation. It was also found that the gradients generated between the interior of the structure and the exterior environment presented values lower than 2.0°C for temperature and −6.3% for relative humidity. These values can be considered low in comparison with other structures evaluated in other regions of the world where the gradients can reach values higher than 10°C and 13% for temperature and relative humidity, respectively.

Smile4life is an intervention aimed at improving the oral health of people experiencing homelessness in Scotland. The purpose of this research was to determine how this intervention was being translated from guidance into action. Data concerning Smile4life working practices were collected in three NHS Boards using participant observation. Fieldnotes taken during these observations were analysed using content analysis. This analysis revealed that there were working alliances between the oral health practitioner, the Third Sector staff, and the homeless service users, and that these alliances were affected by various barriers and enablers. The observation sessions also highlighted variations in working practices.

Young homeless people make up nearly one-third of those experiencing homelessness. The need to provide an educative approach, to strengthen social interacting, and construct new knowledge to increase social inclusivity, is required. The aim of this qualitative exploration was to use critical consciousness as an educative tool, to co-design, implement, and evaluate a series of oral health and health pedagogical workshops to strengthen social engagement and to construct new health knowledge, with, and for, homeless young people and their service providers. An action research design permitted the simultaneous development, implementation, and evaluation of the pedagogical workshop program. A Non-Governmental Organization (NGO), providing supported accommodation for young homeless people, acted as the partner organization. Thirteen young people and five staff members from this NGO participated and co-designed eight workshops. Qualitative data collection included unstructured post-intervention interviews together with verbatim quotes from the group discussions during the workshops and from the post-workshop questionnaires. The qualitative analysis was informed by content analysis to permit the emergence of key themes from the data. The two themes were: 1. ‘trust building and collective engaging’ and 2. ‘constructing knowledge and developing skills’. Theme 1 highlighted engagement with the service provider, illustrating the transformation of the young people’s relationships, strengthening of their social interacting, and enabling their critical reflexive thinking on sensitive issues present in the homelessness trajectory. Theme 2 illustrated the young people’s ability to share, lend, and encode their new health information and convert it into an understandable and useable form. This new comprehension permitted their behavior change and social interaction. These findings provide an approach to increase young people’s knowledge, health literacy, and strengthen their social interacting to support community action.

A contingent valuation method (CVM) study was used to compare survey response rates, protest refusals to pay, and median willingness-to-pay (WTP) of Native American communities in Montana compared to Montana's general population for two wildland fire mitigation strategies. Understanding differences in response rates, protest refusals to pay, and median WTP between Native Americans in the United States and the general population may shed some light on how well the method may work for indigenous people in other developed countries such as Canada, Australia and New Zealand. Native Americans survey response rates were not significantly different from Montana residents for the initial contact (first ARTICLE IN PRESS www.elsevier.de/jfe 1104-6899/$ -see front matter wave), but were significantly different for the follow-up in-depth phone interviews (second wave). Native Americans protest rate for the prescribed burning program was not statistically different from Montana residents. Conventionally calculated, protest rates for the mechanical fuels reduction program are higher for Montana's residents than Native Americans. Results from bivariate probit with sample selection models indicate that there is no significant difference between the Native American and Montana general populations' median WTP for either program. This suggests that in Montana, Native Americans and members of the general population generally yield similar results to CVM questionnaires of forest fire management.
