Abstract: As cultivated land quality has been paid more and more scientific attention, its connotation generalization and cognitive bias are widespread, bringing many challenges to the investigation and evaluation of regional cultivated land quality and its data analysis and mining. Establishing a systematic and interdisciplinary cognitive approach to cultivated land quality is urgent and necessary. Therefore, we explored and developed a conceptual framework of the model for the cultivated land quality analysis from the data perspective, including cultivated land quality ontology, mapping, correlation, and decision models. We identified the primary content of cultivated land quality perceptions and four cognitive mechanisms. We built vital technologies, such as the collaborative perception of the quality of cultivated land, intelligent treatment, diagnostic evaluation, and simulation prediction. Applying this analysis framework, we sorted out the frequency of indicators that characterize the function of cultivated land according to the literature in recent years and have built the cognitive system of cultivated land quality in the black soil region of Northeast China. The system’s central component was production capacity and it had three components: a foundation, a guarantee, and an effect. The black soil region cultivated land quality evaluation system has seven purposes involving 20–31 key indicators: production supply, threat control, farmland infrastructure regulation, cultivated land ecological maintenance, economics, social culture, and environmental protection. In various application contexts, the system had many critical supporting technologies. The results demonstrate that the framework has strong adaptability, efficiency, and scalability, which might offer a theoretical direction for further studies on the evaluation of the quality of cultivated land in the area. The analysis framework established in this study is helpful to deepen the understanding of cultivated land quality systems from the perspective of big data. Taking the big data of cultivated land quality as the driving force, combined with the technical methods of cultivated land quality analysis, the evaluation results of cultivated land quality under different scenarios and different objectives are optimized. In addition, the framework can serve the practice of farmland management and engineering improvement, adapt to the management needs of different objects and different scales, and achieve the combination of theory and practice.

Abstract: High-quality faculties are the fundamental guarantee to achieving the connotation development of higher education. Hence, performing university faculties determines the quality of teaching and the level of talent cultivation. Facing the change in teaching demand and environment, faculties need to change their working methods spontaneously to achieve high-level performance. Relevant empirical studies have shown that empowering leadership positively affects adaptive performance. However, some researchers have found that leadership effectiveness even has a negative effect. There may be two reasons for the inconsistency in the effectiveness of empowering leadership: (1) There is a lack of in-depth research on the effectiveness of empowering leadership and employees’ performance in existing studies, and the exploration of its theoretical mechanism should be enriched. (2) The effectiveness of empowering leadership may be subject to the conditions of the individual’s characteristics of the empowering. Therefore, the mechanism of empowering leadership on faculties’ adaptive performance still needs to be further explored. This study explores the impact of empowering leadership on adaptive performance. Based on Social Exchange Theory and Psychology Empowerment theory, this study explores the mediating role of the leadership-member exchange relationship and psychological empowerment in the relationship between them. According to Regulatory Focus Theory, the moderating role of promotion focus and prevent focus was studied. We adopted questionnaire survey data including 292 individuals in Changchun, Shijiazhuang, and other cities; STATA 15 was conducted to test the hypotheses. The results showed that: (1) Empowering leadership was significantly and positively related to adaptive performance. (2) Leader-member exchange relationship and psychological empowerment play a mediating chain role in empowering leadership and adaptive performance; empowering leadership promotes psychology empowerment by enhancing the leadership-member exchange relationship, enhancing their adaptive performance. (3) Promotion focus positively regulates the relationship between psychological empowerment and adaptive performance. Individuals with a promotion focus have a significant positive impact on adaptive performance. Individuals with preventing focus do not weaken the positive impact of psychological empowerment on adaptive performance.
