Description: Author(s): Jibiao Wang, Hao Guo, and Qijin Chen The pairing and superfluid phenomena in a two-component Fermi gas can be strongly affected by the population and mass imbalances. Here we present phase diagrams of an atomic Fermi-Fermi mixture as they undergo BCS–Bose-Einstein condensation (BEC) crossover using a pairing fluctuation theory. We focu... [Phys. Rev.

Description: Sustainability, Vol. 9, Pages 1853: Analysis of the Driving Forces in Vegetation Variation in the Grain for Green Program Region, China Sustainability doi: 10.3390/su9101853 Authors: Wang Hao Liu Guohua Li Zongshan Ye Xin Fu Bojie Lü Yihe The Chinese government introduced six ecological restoration programs to improve its natural environment. Although these programs have proven successful in improving local environmental conditions, some studies have questioned their effectiveness when regions suffer from extreme weather conditions. Using the Grain for Green Program (GGP) region as a study area, we estimated vegetation activities in the GGP region from 2000 to 2010 to clarify the trends in vegetation growth and their driving forces. The results showed that: (1) vegetation activities improved in the GGP region during 2000-2010, with 58.94% of the area showing an increased trend in the NDVI (normalized difference vegetation index); (2) 26.33% of the increased vegetation was caused by human interference, and 11.61% by climate variation, human activity was the dominant cause, and resulted in 54.68% of the degradation compared to 4.74% from climate change; and, (3) the contribution of different land use types to the NDVI interannual variations showed that high contribution regions were focused in the arid and semiarid areas, where the vegetation growth is associated with variations in recipitation and temperature. However, conversions between farmland and grassland or forest had a significant effect on the change in the NDVI trend. Therefore, although climate conditions can affect vegetation growth, human activities are more important in vegetation changes, and appropriate human activities would contribute to its continual improvement. Hence, we recommend establishing an assessment and scientific management mechanism for eco-risks in the design and management of ecosystem restoration programs.

Description: Sustainability, Vol. 10, Pages 2702: Using Traditional Chinese Medicine Ideas as a Mechanism to Engage People in Health Awareness Sustainability doi: 10.3390/su10082702 Authors: Donglei Song Yu Xia Rusi Wang Hao Xu Improving health awareness is essential to health and healthcare sustainability. How to arouse attention to the health of people and encourage them to attend to healthcare progress so that we can reduce the costs of promoting healthcare by achieving more with less effort remains to be explored. In this paper, we provide a simplified health management app, called iTongue, with a basis in traditional Chinese medicine. People use iTongue to take pictures of their tongues to have a general idea of their health. We realize automated tongue image diagnosis using machine learning techniques to establish the relationship between the tongue image features and the cold or hot ZHENG (traditional Chinese medicine syndrome) in traditional Chinese medicine by learning through examples and assisting people to engage in health management. The results show that health management interaction based on traditional Chinese medicine has a positive influence on improving people’s attention to their health, encouraging them to participate in health management activities and develop the habit of caring about their health over the long term. In the future, we could consider using this kind of traditional Chinese medicine idea as a means of publicity to engage people in healthcare and to assist healthcare sustainability development.

Description: Sustainability, Vol. 10, Pages 800: Splitting and Combining as a Gamification Method in Engaging Structured Knowledge Learning Sustainability doi: 10.3390/su10030800 Authors: Donglei Song Daqian Shi Rusi Wang Hao Xu The understanding of the structure of knowledge is an essential step of education. Although teachers offer the information foundation and relationship among knowledge points, there are still few methods to encourage students to explore the structure of knowledge by themselves outside of classes. This paper explores the gamification method and the knowledge structure of computer science. We assess the gamification method of “splitting and combining” (SC) to encourage students to finish the process of learning structured knowledge in the university. The results show that this method works well in promoting learning enjoyment and that splitting demonstrates better performance than combining. We can consider the SC method when recommending a gamification method to engage students in structural learning assistance in future smart university education.

Description: Sustainability, Vol. 10, Pages 2633: Scenario-Based Simulation of Tianjin City Using a Cellular Automata–Markov Model Sustainability doi: 10.3390/su10082633 Authors: Ruci Wang Hao Hou Yuji Murayama Rapid urbanization is occurring throughout China, especially in megacities. Using a land use model to obtain future land use/cover conditions is an essential method to prevent chaotic urban sprawl and imbalanced development. This study utilized historical Landsat images to create land use/cover maps to predict the land use/cover changes of Tianjin city in 2025 and 2035. The cellular automata–Markov (CA–Markov) model was applied in the simulation under three scenarios: the environmental protection scenario (EPS), crop protection scenario (CPS), and spontaneous scenario (SS). The model achieved a kappa value of 86.6% with a figure of merit (FoM) of 12.18% when compared to the empirical land use/cover map in 2015. The results showed that the occupation of built-up areas increased from 29.13% in 2015 to 38.68% (EPS), 36.18% (CPS), and 47.94% (SS) in 2035. In this context, current urbanization would bring unprecedented stress on agricultural resources and forest ecosystems, which could be attenuated by implementing protection policies along with decelerating urban expansion. The findings provide valuable information for urban planners to achieve sustainable development goals.

Description: Sustainability, Vol. 10, Pages 582: Does a Board Chairman’s Political Connection Affect Green Investment?—From a Sustainable Perspective Sustainability doi: 10.3390/su10030582 Authors: Kai Wang Hao-Min Zhang Sang-Bing Tsai Li-Dong Wu Kun-Kun Xue He-Jun Fan Jie Zhou Quan Chen Using a sample consisting of China’s listed manufacturing companies which issue A-shares on the Shenzhen and Shanghai stock exchanges from 2008–2014, this study empirically tests the relationship between board chairman’s political connections and the amount of energy conservation and emission reduction investment. The results show that the existence of politically-connected board chairmen positively affects green investment. In addition, marketization degrees negatively moderate the relationship between political connection and green investment, which supports an institutional logic perspective. The amount of redundant resources also has the same moderating effect, which is consistent with the resource exchange perspective.
