Abstract	In recent years, the retrieval and validation of remotely-sensed leaf area index (LAI) products over complex land surfaces have received much attention due to the high-precision land surface model simulations and applications in global climate change. However, most of these related researches mainly focus on coarse resolution products. This is because few products have been specifically designed for solving the problems derived from complex land surfaces in mountain areas until now. MuSyQ LAI is a new product derived from Gaofen-1 (GF-1) satellite data. This product is characterized with a temporal resolution of 10 days and a spatial resolution of 16 m. As is well known, high-resolution products have less uncertainties because of the homogeneities of sub-pixel. Therefore, to evaluate the precision and uncertainty of MuSyQ LAI, an up-scaling strategy was employed here to validate MuSyQ LAI for three mountain regions in Southwest China. The validation strategy can be divided into three parts. First, a regression model was built by in situ LAI measured by LAI-2200 and the normalized difference vegetation index (NDVI) from unmanned aerial vehicle (UAV) images to obtain a 0.5 m resolution LAI map. Second, an up-scaled LAI map with a spatial resolution consistent with MuSyQ LAI was calculated by the pixel-averaging method from the UAV-based LAI map. Third, the MuSyQ LAI was validated by the up-scaled UAV-based LAI in pixel scale. Simultaneously, the sources of uncertainty were analyzed and compared from the view of data source, retrieval model, and scale effects. The results suggested that MuSyQ LAI in the study areas are significantly underestimated by 53.69% due to the complex terrain and heterogeneous land cover. There are three main reasons for the underestimation. The differences between GF-1 reflectance and UAV-based reflectance employed to estimate LAI are the largest factors for the validation results, even accounting for 61.47% of the total bias. Subsequently, the scale effects led to about 28.44% bias. Last ...

Abstract	BackgroundInterventions targeting single behaviors of preschool-aged children have been mainstream for some time, but integrated interventions targeting all three 24-h movement behaviors (physical activity [PA], sedentary behavior [SB], and sleep hygiene) are less studied. The aims of this study will be to test the feasibility, acceptability, and effectiveness of a parent-focused intervention for preschool-aged children targeting multiple 24-h movement behaviors.MethodsThis three-arm randomized controlled trial will comprise a 12-week intervention and a 12-week follow-up. A total of 150 parent-child dyads will be recruited and randomly allocated to one of three arms: (1) a PA + SB group (dyadic approach), (2) a PA + SB + sleep group (integrated approach), and (3) a wait-list control group. The theory of planned behavior and behavioral change techniques will guide the development of the intervention via workshops, education materials, interactive questionnaires, and reminders. The intervention strategies for the integrated group will be the same as for the dyadic approach except that the intervention will also target sleep hygiene in addition to PA and SB. The primary outcomes will be preschoolers' 24-h movement behaviors (e.g., activity sleep index, compositional data of PA, SB, screen time, and sleep duration). The secondary outcomes will be preschoolers' sleep quality, weight status, cognitive function, and parents' movement behaviors. The feasibility and acceptability of the intervention will also be evaluated.DiscussionThe proposed study will be a theory-based, parent-focused intervention designed to improve all three 24-h movement behaviors among preschoolers. The trial is expected to improve preschoolers' movement behaviors and health outcomes, as well as their parents' movement behaviors. Given the urgent need to promote active lifestyles, our findings will help to determine best practices for movement behavior change among young children.Trial RegistrationThe study is prospectively registered at the ...

Abstract	The Yunnan-Guizhou Plateau (YGP) is a typical ecologically fragile region in southwest China. Water-erosion desertification (WED) is one of the most significant environmental and socio-economic issues on the YGP and has seriously restricted the socio-economic development of this region. However, the research on monitoring of the desertification trends in this region has been limited to long time-series Landsat imagery. The objectives of this research were to monitor the WED trends on the YGP using time-series Landsat imagery data from 1989 to 2016. In this paper, we present a multi-indicator rule-based method, which was used to map the WED on the YGP during this period. The results show that the addition of multiple indicators improved the WED classification accuracy to 90.61%. Overall, the following results were obtained by using the proposed method. (1) The slight desertification area on the YGP increased from 89,617.09 km2 in 1989 to 100,976.47 km2 in 2016 with an annual growth ratio (AGR) of 0.48%, the moderate desertification area increased from 80,276.65 km2 in 1989 to 90,768.39 km2 in 2016 with an AGR of 0.50%, and the severe desertification area increased from 8149.3 km2 in 1989 to 13,220.16 km2 in 2016 with an AGR of 2.39%. (2) The WED expansion on the YGP can be divided into three stages. Firstly, the total WED area increased slowly from 17.80×104 km2 in 1989 to 17.98×104 km2 in 2010 with an AGR of 0.05%. Then, the WED rapidly expanded from 17.98×104 km2 in 2010 to 20.28×104 km2 in 2013 with an AGR of 4.26%. Finally, the WED increased slightly from 20.28×104 km2 in 2013 to 20.50×104 km2 in 2016 with an AGR of 0.36%. The total areas of the different degrees of WED decreased in 1992, 1998, 2001, and 2004. (3) The driving factors of WED were analyzed based on the Geographically Weighted Regression (GWR) model. We found that precipitation, vegetation area, and gross domestic product have key roles in the processes of desertification reversion and development. However, the regression coefficients between WED and these factors exhibited considerable spatial variations. The regression coefficients of the key driving factors showed different spatial distributions based on the GWR model in the YGP. The research results can provide scientific reference information for the prevention and control of WED in the YGP.

Abstract	Insufficient physical activity (PA) is a leading risk factor for mortality. The Active Healthy Kids Report Cards provide comprehensive evidence related to PA in children/adolescents. Associations of (1) parental support for PA with amount of moderate-to-vigorous-intensity PA (MVPA) performed by children/adolescents and (2) amount of MVPA performed by parents with amount of MVPA performed by children/adolescents, as indicated by Report Cards, have not been critically synthesized in meta-analysis. We selected data in Asian countries/regions Report Cards and performed meta-analyses to assess pooled associations of influence indicators and behavior indicators among children/adolescents in Asian countries/regions. Our meta-analyses included five studies that assessed association of parental support or MVPA performance with child/adolescent MVPA performance. Positive association was observed between the amount of time spent by parents on MVPA per week, regardless of gender, and the amount of time spent by children and adolescents on MVPA per week (

Abstract	Abstract Background The information technology has developed rapidly with the evolution of internet environment transformed from requiring computer skills for information searching to self-managing health data and applying information. Therefore, a more diverse range of eHealth skills is required and these skills are referred as eHealth literacy. However, most eHealth literacy studies focused mainly on information searching skills. Little is known about eHealth usage behaviors of college students in this day and age. Objectives This study aimed to investigate how Chinese college students engage with eHealth tools and to determine the elements of their eHealth literacy. Methods A purposive sample of 18 Chinese college students was recruited for in-depth interviews. Interviewees included three males and three females of each city (Beijing, Wuhan and Putian) from sports, medical, and non-health-related majors. Conventional content analysis was applied for data analysis. Results The eHealth usage of different-major-students were compared and profiled by three themes of Expectance, Usage pattern and Perception. In Expectances, non-health major students applied eHealth only for urgent health need, sport major students used it to monitor health while medical major students, as frequent users for searching health database. In Usage pattern, purposes of eHealth for personal, practical and theoretical were identified for non-health major, sport major and medical major groups, respectively. In Perceptions, sport students felt more curious about eHealth than the other groups who perceived either fear (non-health students) or skeptical (medical students). By compiling those themes, the whole picture of eHealth usage was emerged. Based on that, the current study identified the related skills using the trilogy of Web 1.0 to 3.0, and derived a conceptual framework for eHealth literacy in the present day. Conclusions The current study obtained a comprehensive understanding of eHealth usage and a framework of eHealth literacy ...

Abstract	Abstract With the rise of data capital and its instantaneous economic effects, existing data-sharing agreements have become complicated and are insufficient for capitalizing on the full value of the data resource. The challenge is to figure out how to derive benefits from data via the right to data portability. Among these, data ownership issues are complex and currently lack a concept that enables the right to data portability, is conducive to the free flow of cross-border data, and assists in the economic agglomeration of cyberspace. We propose defining the term “data sovereign” as a person or entity with the ability to possess and protect the data. First, the word “sovereign” is borrowed from the fundamental economic notion of William H. Hutt’s “consumer sovereignty.” This notion of sovereignty is strengthened by Max Weber’s classic definition of “power” – the ability to possess any resource. We envision that data capital would provide greater “cross-border” convenience for engaging in transactions and exchanges with very different cultures and societies. In our formulation, data sovereign status is achieved when one both possesses the data and can defend any attack on that data. Using “force” to protect data does not imply an abandonment of data sharing. Rather, it should be easy for an organization to enable the sharing of data and data products internally or with trusted partners. Examples of an attack on the data might be a data breach scandal, identity theft, or data terrorism. In the future, numerous tedious, time-consuming, non-artistry, manual occupational tasks can be replaced by data products that are part of a global data economy.

Abstract	Purpose: The aim of the study was to investigate perceptions of staff about the promotion of physical activity (PA) in selected group residences of Hong Kong (HK), some of which had experienced a multi-component PA program. Method: Focus group interviews with nineteen staff members from four group homes (two of which received the program) were conducted. Findings: A SWOT analysis provided important insights into residential staff views about key influences on the quality of PA programs for residents with intellectual disabilities (ID). Positive (strengths and opportunities) and negative (weaknesses and threats) influences were identified. They were associated with characteristics of residents, staff, and group residence. Increasing age and low motivation are impediments to PA engagement of adults with ID. Staff competence and prior unsuccessful experience in promoting PA are also implicated. Conclusion: The PA program quality is mediated by the quality of staff interpersonal interactions with their clients and their commitment in encouraging such adults with ID to join and persistent in PA as well as staff seeking external resources and support as well as using initiative to adapt PA promotion activities in their specific group residential context.

Abstract	The purpose of this paper was to examine the benefits of dance in providing a realistic and viable alternative to the provision of traditional physical activities for dementia patients. Physical activity, while beneficial for increasing the components of health and fitness in general populations, may not be dementia friendly. Dance seems to be more suited as a physical activity form for dementia patients providing specific benefits including cerebrovascular enhancement. The usefulness of dance in relation to the physiological, psychological, and societal benefits for dementia patients’ needs serious consideration as a future complementary/alternative physical therapy intervention.

Abstract	Abstract Background Adolescents (11–18-year-olds) are at risk of physical inactivity. There is limited knowledge of physical activity (PA) levels among adolescents in the school setting in Hong Kong. We developed and tested a novel theoretical model of how household/family characteristics, school-level social and physical environmental factors and individual adolescent’s characteristics impact on their school-based PA during and after school hours. Methods Cross-sectional study participants were Hong Kong adolescents attending secondary school, paired with their parent/caregiver (n = 1299 dyads). Parents survey-reported on household/family characteristics, parental PA and rules related to PA. Adolescents survey-reported on school PA-friendly policy, PA equipment at school (combined to create PA-friendly index), social support for PA from peers, athletic ability, attitude to and enjoyment of PA. Adolescents self-reported their school-based PA during school hours (physical education; recess) and after school (sports teams/classes). Objectively-measured moderate-to-vigorous PA (MVPA) was measured using accelerometers for a sub-sample of adolescents (n = 588). Generalized additive mixed models were used to estimate how household/family-level and school-level factors, and adolescents’ individual characteristics were related to adolescents’ school-based PA in Hong Kong, and to identify potential mediators of these associations. Results A complex network of potential pathways of influence on adolescents’ school-based PA was identified. Overall, most of the significant effects were indirect ones. However, there were far fewer significant pathways between household/family characteristics and objectively-measured MVPA at school than there were for self-reported PA at school. In fact, there were no indirect pathways between these variables and MVPA at school. Gender disparities among pathways were identified. For example, school PA-friendly index was significantly associated with MVPA after school only among girls (eb = ...
