Museum visitors are not reflective of the diversity present in communities around the nation. In this study, we investigate the racial and ethnic diversity of art museum participants as well as the potential motivations and barriers to visiting a museum. Using the General Social Survey, we examine race and ethnicity and arts participation in the USA. We find Black individuals are less likely to attend an art museum than white individuals. Certain motivations and barriers to participating may explain part of the lack of diversity. We find Black and Latinx individuals are motivated to participate in art museums for cultural heritage reasons more than white individuals, but race and ethnicity are unrelated to perceiving admission fees as a barrier. This research highlights the urgency in the field to make museums more inclusive.

Developing countries throughout the world currently fuel kitchen stoves for cooking by burning wood which is responsible for many health and environmental problems. Producing fuel for cooking via anaerobic digestion is a very ecofriendly and resourceful solution that is being explored. To determine the sustainability of anaerobic digestion throughout these regions, multiple biodigester designs were tested under conditions specific to various third-world countries; the countries tested were Nicaragua, Bolivia, Nigeria, India and Indonesia. Factors to be considered included the use of local biomass resources and building materials. Determining the fueling efficiency of anaerobic digestion in comparison to burning wood consisted of evaluating the production costs and environmental impacts. This was accomplished utilizing technoeconomic analysis (TEA) and life cycle assessment (LCA). TEA results indicated that tube digesters are the most cost effective method of anaerobic digestion in all countries tested; tube digestion at a family scale ranged from approximately $0.24 per meal to $0.73 per meal. The LCA showed that operation of anaerobic digestion required much more water than previously considered which may cause it to not be a sustainable method. However, it did emit a much lower amount of carbon dioxide than burning wood. The CO 2 emissions per meal ranged from 0.97 kg per meal to 1.29 kg per meal. The water impacts ranged from 76 L/ meal to 100 L/meal. Comparing the two fueling methods proved that anaerobic digestion was a more economically and environmentally effective process. Abstract.
