Based on network analysis, different trip modes were integrated into an improved potential model, and the geography of the spatial equity of nursing homes in Changchun is explored in 5-min, 10-min and 15-min scenarios, respectively. Results show that: (1) trip modes have significant influence on spatial equity and that the geography of spatial equity varied with trip modes; (2) the spatial equity value in Changchun is overall kept to a very low level. Most areas in urban fringes and urban core areas belong to underserved areas, and the capacity of nursing home, travel cost and the number of seniors, are the main influencing factors; (3) the geography of spatial equity in different scenarios show a very similar ring structure; namely, the spatial equity value within the urban core and at the most urban periphery is lower than that in intermediate areas. The hot spot analysis showed that the southwest urban fringes and east of the urban core are hot spot areas, while the urban core itself has cold spot areas.

The library community has been committed to environmental sustainability. The Green Library Movement calls for libraries to green their building, operation, and services. The International Federation of Library Associations and Institutions (IFLA) calls for libraries to actively contribute to the United Nations Sustainable Development Goals (SDGs) in which environmental sustainability was one of the three aspects of sustainability in addition to social and economic sustainability. The American Library Association (ALA) has also added sustainability as one of the core values of librarianship. However, previous research identified a gap between librarians’ perceived importance of environmental sustainability and the actual practices adopted in their libraries that contribute to environmental sustainability. This current study focuses on examining librarians’ attitudes toward the roles of libraries in environmental sustainability advocated by IFLA and ALA by surveying librarians from California, Florida, and Georgia identified from the state library association listservs and the individual library websites. Data were analyzed using descriptive and inferential statistics and the Geographic Information System (GIS) spatial analysis. Findings from this study will add to the understanding of the previously identified gap by comprehending the roles that librarians identify with regarding libraries’ contribution to environmental sustainability. The findings will also inform professional organizations on what support their members might need the most in promoting environmental sustainability in society and community. Lastly, the findings could inform curricular development for Library and Information Studies programs interested in preparing librarians with environmental awareness.
