The primary purpose of this research is to determine influential indoor and outdoor environmental elements that affect senior households’ perceptions of housing affordability. This paper proposes major considerations for indoor and outdoor environmental elements which could make homes for senior households to be affordable and thus support their ageing in place. Our research adopted an empirical approach based on a survey. Relevant research was reviewed to identify potential indoor and outdoor environmental elements that could affect senior residents’ opinions about housing affordability. Sixteen indoor and outdoor environmental elements were selected. The survey targeted senior residents living in the central Michigan area in the United States. The results of this paper were based on descriptive statistics, mean difference tests, correlation coefficients and regression models to explain the relationships between indoor and outdoor environmental elements and senior residents’ perceptions of their housing affordability. Major findings proved statistically significant correlations between interior environmental elements and senior households’ perceived housing affordability. Most housing programmes and policies for housing affordability have focused on financial elements. Findings from this research, however, added several indoor and neighbourhood environmental elements for consideration to improve senior households’ perceived housing affordability and support their ageing in place.

Myzocallidium riehmi (Börner) was collected from sweet clover at Creston in June, 1957. This is the first time this aphid of potential economic importance has been identified from British Columbia. It occurs throughout the United States (Russell, 1957); in Ontario, Ottawa being near the northern limit of its range (W. R. Richards, in litt.); and was identified for the first time from Manitoba in 1956 (Bird and Robinson, 1957)

Abstract Background Mayaro virus (MAYV; Alphavirus, Togaviridae) is an emerging pathogen endemic in South American countries. The increase in intercontinental travel and tourism-based forest excursions has resulted in an increase in MAYV spread, with imported cases observed in Europe and North America. Intriguingly, no local transmission of MAYV has been reported outside South America, despite the presence of potential vectors.Methods We assessed the vector competence of Aedes albopictus from New York and Anopheles quadrimaculatus for MAYV. Results We showed that Aedes albopictus from New York and Anopheles quadrimaculatus are competent vectors for MAYV. However, Aedes albopictus was more susceptible to infection. Transmission rates increased with time for both species with rates of 37.21% and 64.44% for Aedes albopictus, and 31.11% and 46.34% for Anopheles quadrimaculatus, respectively, at 7 and 14 days-post-infection. Conclusions Our results suggest there is a risk of further MAYV spread throughout the Americas and autochthonous transmission in the United States. Preventive measures such as mosquito surveillance of MAYV will be essential for early detection.
