A number of national, regional and global land cover classification systems have been developed to meet specific user requirements for land cover mapping exercises, independent of scale, nomenclature and quality. However, this variety of land-cover classification systems limits the compatibility and comparability of land cover data. Furthermore, the current lack of interoperability between different land cover datasets, often stemming from incompatible land cover classification systems, makes analysis of multi-source, heterogeneous land cover data for various applications a very difficult task. This paper provides a critical review of the harmonization of land cover classification systems, which facilitates the generation, use and analysis of land cover maps consistently. Harmonization of existing land cover classification systems is essential to improve their cross-comparison and validation for understanding landscape patterns and changes. The paper reviews major land cover classification standards according to different scales, summarizes studies on harmonizing land cover mapping, and discusses some research problems that need to be solved and some future research directions.

Due to rapid changes in urban and rural economic development, the Chinese landscape has been gradually transforming toward urbanization. Most Chinese rural villages face declining problems such as population loss, land use transformation, fragmentation and abandonment, resulting in big changes in the rural spatial morphology. To understand these urbanization challenges, this study established a multi-factor methodology and applied it to a case study of three selected typical villages in southern Jiangsu Province. From this analysis, the quantification of the rural spatial morphology and environmental status, from 2005 to 2016, was determined. The eight driving factors established considered the rural geological location, landform, and social economic status. To analyze the driving factors, a quantitative analysis using ArcGIS, Environment for Visualizing Images (ENVI), and Analytic Network Process (ANP) decision-making methods were used. The results revealed mechanisms between the changes to spatial morphology of rural villages in southern Jiangsu Province and their key driving factors. This study provides data support and a theoretical framework to guide future development and policy of rural villages of different types, which supports the sustainable development of Chinese rural villages.

Zircon has been widely applied in various traditional and emerging fields due to its distinct physiochemical advantages while monodisperse spherical zircon (MSZ) powders hitherto have not been explored for the tremendous challenges in the control of zircon crystallization and growth. Herein, systematic investigations are presented to reveal the paramount role of halide mineralizers upon the crystallization and growth of MSZ powders synthesized under highly acidic hydrothermal environments (pH <0). A formation mechanism is revealed revolving around the complexation of central Zr4+ with the Lewis basic ligand, fluorine, which forms the F‐containing species of [(OH)1–y·Ry] (R = F, Cl) to replace Zr and generates Zr‐deficient zircons as (ZrO4)1‐xSi[(OH)1‐y·Ry]4x. This finding differs much from conventional views on common fluoro‐hydroxylated hydrothermal zircons, which were generally regarded as Si‐deficient silicates from the substitution of fluoro‐hydroxyls for the [SiO4] tetrahedra. A parameter, Kr=4xy, is first proposed as an index to evaluate the stability of hydrothermal zircons. The MSZ powders demonstrate superb thermal stability at high temperature, superior photo‐reflectance, and thermal insulation over normal zircons, promising attractive prospects to extend zircon applications.

Objective The aim of this study was to investigate the effect of Health Qigong (HQ) exercise on the subjective and objective sleep quality and the quality of life in male patients with drug abuse who received treatment at a mandatory drug rehabilitation residential institution. Methods Ninety male patients (mean age, 36.85 ± 8.72 y) were included and randomly divided into the Health Qigong (HQ) group, aerobic exercise (AE) group, or control group. The participants in the HQ and AE groups exercised four times a week for 1 hour per session for 12 weeks, while the control group maintained their original lifestyle. The following parameters were recorded before and after exercise: Pittsburgh Sleep Quality Index (PSQI); SF-36; and total sleep time, sleep efficiency, sleep latency, deep sleep time, deep sleep rate, light sleep time, and light sleep rate using actigraphy. Results Health Qigong improved the subjective sleep quality, objective sleep quality, and quality of life after a 12-week intervention. Considering the subjective sleep quality, Health Qigong helped improve several aspects of the PSQI, including the overall sleep quality ( p < 0.01), sleep latency ( p < 0.01), sleep duration ( p < 0.01), sleep latency ( p < 0.01), sleep disturbance ( p < 0.01), and day dysfunction ( p < 0.01). In relation to the objective sleep quality, Health Qigong improved the total sleep time ( p < 0.01), sleep efficiency ( p < 0.01), sleep latency ( p < 0.01), deep and light sleep rate ( p < 0.01). Considering the quality of life, Health Qigong helped improve the role-physical ( p < 0.01), general health ( p < 0.01), bodily pain ( p < 0.01), and mental health ( p < 0.01) aspects of SF-36. Conclusion Health Qigong may be an effective approach to improve the subjective and objective quality of sleep and life quality of patients with drug abuse.

Purpose This study aims to explore how female leadership contributes to corporate innovation through a systematic literature review. The authors provide a framework based on empirical studies to provide a broader perspective of corporate innovation based on female leadership. Design/methodology/approach To understand the most recent developments in leadership, a thorough literature study is carried out to discover the antecedents of women’s leadership and their contribution to corporate innovation, with an emphasis on literature published between 2013 and 2022. An intensive research plan was developed, and 1,120 outcomes were obtained. Finally, 35 studies met the criteria for inclusion in the study. A comprehensive and systematic approach is followed, with the goal of not just summarizing current empirical studies on the subject, but also including an aspect of analytical critique besides organizational policies. Findings The findings show that organizations with female chief executive officers (CEOs) are more likely to innovate. When female CEOs come on board, organizations are more likely to engage in creative activities. Research also reveals that female CEOs who head organizations are more likely to engage in new and creative business practices that are environment friendly. Moreover, developing nations are encouraged to accelerate the adoption of structural transformation initiatives that would provide women with access to information and technologies. Research limitations/implications This research is limited to literature published between 2013 and 2022. Practical implications It is important to select the organizational response to board female representation institutional logic to reflect the intended sort of performance. Organizational stakeholders were unfavorable to female leadership, implying that such perceptions harm women but benefit men. Prior research emphasizes distinctions in leadership effectiveness between males and females, diverting attention elsewhere from examining the reasons that generate differences among executives in organizations. For policymakers to promote more women in top positions based on female knowledge, skills and abilities (KSAs), they need to understand how firms deviate from traditional standards. In addition, it is crucial to pay attention to how male and female leaders are supported by their followers. Social implications This research offers organizations a holistic view regarding female leadership and helps them understand their contribution in innovation. Originality/value In modern, dynamic and technological landscapes, female participation is one of the key aspects that corporates consider to sustain and drive growth. That is why, modern societies without women’s contribution to economic growth and innovation are deemed incomplete. The current study highlights their contribution to the economy. Literature also indicates that the presence of female leadership on boards impacts corporate innovation, as well as financial performance and contextual factors.c
