Abstract
Public attitudes towards local university matters for the resource investment to sustainable science and technology. The application of machine learning techniques enables the evaluation of resource investments more precisely even at the national scale. In this study, a total number of 4327 selfies were collected from the social network services (SNS) platform of Sina Micro-Blog for check-in records of 92 211-Project university campuses from 82 cities of 31 Provinces across mainland China. Photos were analyzed by the FireFACETM-V1.0 software to obtain scores of happy and sad facial expressions and a positive response index (PRI) was calculated (happy-sad). One-way analysis of variance indicated that both happy and PRI scores were highest in Shandong University and lowest in Harbin Engineering University. The national distribution of positive expression scores was highest in Changchun, Jinan, and Guangzhou cities. The maximum likelihood estimates from general linear regression indicated that the city-variable of the number of regular institutions of higher learning had the positive contribution to the happy score. The number of internet accesses and area of residential housing contributed to the negative expression scores. Therefore, people tend to show positive expression at campuses in cities with more education infrastructures but fewer residences and internet users. The geospatial analysis of facial expression data can be one approach to supply theoretical evidence for the resource arrangement of sustainable science and technology from universities.
Highlights
Since 2008 more than half of the world population lived in cities and this is expected to reach 70%by 2050 [1]
Overall universities in Beijing City showed a moderate score of positive expressions some university campuses therein obtained higher happy expression scores (e.g., China University of Political Science and Law)
We examined how facial expressions of young adults varied at key universities in the
Summary
Since 2008 more than half of the world population lived in cities and this is expected to reach 70%by 2050 [1]. Since 2008 more than half of the world population lived in cities and this is expected to reach 70%. Cities are widely regarded as important areas in the pursuit of global sustainability [2]. A sustainable society comprises five distinct elements for every human-being such as the proper education, a clean environment, a well-balanced safety, abundant resources for future generation, and contribution to a sustainable world [3]. Easy to collect metrics that rate environmental, economic, educational, and social variables are important to evaluate the global strategies for urban transformation towards sustainability that builds upon national and local scales [4]. A sustainable city should respond to residents’ needs through sustainable solutions for social and economic aspects [1]. The tradeoff between resource consumption and citizens’ demand can be sustainably solved by the use of information
