Objective: The purpose of this study was to investigate how locus of control, coping strategies, emotion regulation strategies and social support affect posttraumatic growth. Methods: A cross‐sectional study design was adopted. A convenience sample of 540 patients with lung cancer was recruited from November 2016 to July 2017 at two tertiary grade A hospitals in China. The participants completed a series of questionnaires. Structural equation modelling was used to explore the effects of psychosocial factors on posttraumatic growth. Results: Social support had a direct positive effect on posttraumatic growth (β = 0.318, SE = 0.071, BC 95% CI = 0.252/0.390), and it also had indirect effects on posttraumatic growth (β = 0.112, SE = 0.023, BC 95%CI = 0.088/0.135) through mediating psychological factors. Coping strategies and the cognitive reappraisal emotion regulation strategy were the main mediating variables, explaining approximately 73.1% of the indirect effect between social support and posttraumatic growth. Conclusions: Our study suggests that Chinese lung cancer survivors can show relatively high posttraumatic growth. There are many mediating paths between social support and posttraumatic growth. These results may help healthcare professionals to identify the psychosocial factors that may benefit lung cancer patients and develop interventions to promote posttraumatic growth.

• Remote sensing data from 1962–2018 were used to analyze coastal lagoon–tidal inlet. • Four shoal-sandbar breaching and tidal-inlet migration events were observed. • A conceptual model for cyclic periodic evolution of ebb-tidal deltas was proposed. • The crucial factors of long-term and short-term in their evolution were discussed. • Remote sensing can be used for early warning of the evolution of ebb-tidal deltas. Coastal lagoon–tidal inlet systems occur worldwide, and each has its own unique evolution characteristics in relation to its geographical location, sediment characteristics, and tidal current and ocean wave conditions. However, insufficient observation data means that it is often difficult to fully understand the long-term and short-term evolution of ebb-tidal deltas, and it is even more difficult to monitor and warn against their evolution. This study uses long time-series remote sensing data for the period 1962–2018 to investigate the evolution of an ebb-tidal delta in Xincun Lagoon, Hainan Island, China. Four shoal-sandbar breaching and tidal-inlet migration events were observed, and the corresponding periodic variation characteristics of the ebb-tidal delta were documented. A conceptual model for the periodic evolution of ebb-tidal deltas was also proposed. The results showed that the long-period (15–20 years) evolution was controlled by the effects of seabed friction and tidal-scale lagoon resonance, while the changes in the length of the east sand-spit could be used as a significant early warning indicator for shoal-sandbar breaching and tidal-inlet migration events. In addition, both types of event were jointly triggered by typhoon storm-surges and the accompanying heavy rainfall, strong winds, and strong waves. Thus, the periodic evolution process of the ebb-tidal delta in Xincun Lagoon was determined to be a systematic process that is either controlled or influenced by a series of interconnecting factors. Moreover, we concluded that it is both feasible and valuable to establish a monitoring and early warning framework of ebb-tidal deltas through the use of time-series remote sensing images. The results of this study can improve the existing understanding of the processes and driving factors of periodic shoal-sandbar breaching and tidal-inlet migration, and can also increase safety nourishment for coastal lagoon–tidal inlet systems.

Version 05 of the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG) includes IMERG-E, IMERG-L, and IMERG-F with spatial resolution of 0.1° × 0.1°. Evaluation over a hilly and Karst landform combined basin in the tropics is necessary to be done to verify the acceptability of the use of IMERG V05. In this study, IMERG Data (ID) are compared with Ground Precipitation Data (GPD) from 15 stations over the Nanliujiang River Basin in China. The comparison is quantified using some statistical indices to analysis detection capability, correlation, and error evaluation. The results show that IMERG-F performs better than IMERG-E and IMERG-L. All three products can detect precipitation under different rainfall intensity effectively. A positive relationship between Pearson's correlation coefficient (r) and temporal scales has been found within both single station and whole basin scales. At a single station scale, r of 14 stations are greater than 0.6 (daily scale) and 0.8 (monthly scale), Relative Bias (RB) ranges from 0.458 to 0.013, and the value of Root-Mean Square Error (RMSE) on daily scale and monthly scale is ranging from 7.38 to 12.51 mm and from 40.17 to 69.01 mm, respectively. At the whole basin scale, products got r values in daily, monthly, and seasonal scale within the range of 0.698 to 0.741, 0.867 to 0.918 and 0.940 to 0.950, respectively. RB in summer is smaller than 0.35, and a more underestimation of precipitation occurs during the winter season of the Northern Hemisphere. The values of monthly RMSE are distributed from 2.841 to 18.949 mm, while the seasonal RMSE has a higher value in summer. Conclusively, IMERG V05 can be considered as an auxiliary tool for precipitation observation in the regions with similar characteristics. [ABSTRACT FROM AUTHOR]

The Integrated development of Tibet " one river and two streams" agricultural ecological basin should control the generated environmental problems and prevent new environmental problems, thereby promoting coordinated development of agricultural economy In the region. It Is very necessary and urgent to explore main environmental problems of Tibet " one river and two streams" agricultural ecological basin and effective countermeasures. When developing resources and economy, the principle of combining prevention with control, dominated by prevention and integrated control should be followed; regional advantages, characteristics and environmental self restoring ability should be sufficiently played and used; the policy of Integrated prevention and utilization should be used; compensation method, prevention control measures and planning assumption for main environmental problems should be proposed, which could prevent that systemic development of Tibet " one river and two streams" agricultural ecological basin takes the old path of " firstly destroying and then controlling".

Tibet Autonomous Region is located in the southwest of China. As a special area with high altitude, low temperature, abundant and diverse resources, the development of agricultural modernization has itself development attribute and feature. Agricultural development area of Tibet mainly concentrates in the "one river and two streams" basin. In this paper, combining the development of modern agriculture on the plateau, the connotation and characteristics of the development of plateau modern agriculture are illustrated from the angle of environment economics. Based on the observation method, linking theory with practice and combining literature research method, descriptive study is conducted, and the specific problems in the development of plateau modern agriculture in the agricultural basin are found. For example, the development of agriculture in Tibet has low utilization rate of resources and unbalanced distribution, agricultural mechanization shows gradient development, productivity and agricultural extension are backward, efforts to promote innovation and science knowledge are not enough, agricultural pollution expands, and the awareness of environmental protection is low. In view of the above problems, we put forward some countermeasures and suggestions: developing local advantage characteristic agriculture, developing cooperative economic organization, establishing the training promotion mode of theory combining with practice, establishing agricultural industry system of sightseeing tourism ecology. The research could provide theoretical suggestions for the future development of plateau modern agriculture. [ABSTRACT FROM AUTHOR]

Islands, which provide multiple ecosystem services, are subject to increasing urbanization pressure due to the ongoing marine development, especially in developing countries. Insights into the island urbanization mechanism and its ecological consequences are essential to sustainable development. In the present paper, the satellite images, nighttime lights, and topographic data were integrated to characterize the spatially explicit urbanization process and mechanism during 1995–2011 in the Zhoushan Island, East China. Furthermore, the corresponding spatially explicit changes in ecosystem services, including net primary productivity (NPP), carbon sequestration and oxygen production (CSOP), nutrient cycling, crop production, and habitat quality, were quantified based on the Carnegie–Ames–Stanford Approach (CASA) and Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) models. The results showed that the Zhoushan Island had experienced a rapid urbanization over the years, with significant urban encroachment on the farmland and tidal flat. Moreover, the urban land expansion was positively correlated with that of the nighttime lights and negatively correlated with the elevation, slope, and the distance to shoreline. These indicated that the urban expansion was resulted from the enhancement of socioeconomic activities, and concentrated in the near-shore areas with low altitude and gentle slope. The urban encroachment on other land use types resulted in a decrease of 3.4 Gg C a −1 NPP, 8.7 Gg a −1 CSOP, 13.2 Gg a −1 nutrient cycling, and 12.3 t a −1 crop production, respectively. In addition, the habitat quality in 11% area of this island degraded substantially. Therefore, to achieve sustainable development of islands, it is urgent to implement more stringent policies, such as island spatial regulation, environmental impact assessment, intensive land use, and urban greening, etc. [ABSTRACT FROM AUTHOR]

An improved understanding of global Urban Exposure to Flooding (UEF) is essential for developing risk-reduction strategies for sustainable urban development. This study is the first to assess the long-term historical global UEF at a fine spatial resolution (i.e., 30 m) and annual temporal frequency, with consideration of smaller urban areas in the exposure assessment compared to those using coarse resolution data. We assessed the UEF by investigating the spatially explicit urban expansion in the 100-year floodplain extents. The global UEF increased more than four-fold from 16,443 km 2 in 1985 to 92,233 km 2 in 2018 with accelerated temporal trends. The most notable growth in UEF occurred in Asia (74.1%), followed by Europe (11.6%), Northern America (8.7%), Africa (2.9%), Southern America (2.2%), and Australia (0.5%). Notably, China and US were the two countries with the largest UEF, accounting for about 61.5% of global growth in UEF. In addition, only 1.2% of global floodplains were occupied by urban expansion by 2018, whereas this percentage reached 20% in the basins of Western Europe, Eastern Asia, and Northeastern US. Moreover, although the floodplains only accounted for 5.5% of the global land areas, 12.6% of the urban expansion occurred in the floodplains from 1985 to 2018, with the most rapid increases in the basins in Southeastern and Eastern China. Our findings highlight that the trends of accelerated increasing urban exposure to flooding have been occurring for at least the past three decades., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Background: Although fatigue has been shown to be strongly associated with falls risk, very few studies have focused on its mechanism involved in community-dwelling older subjects. The purpose of this study was to explore the relationship between fatigue and falls risk and its internal mechanism by constructing a chain mediation model., Methods: A cross-sectional study design was adopted. A convenience sample of 270 older adults was recruited from July to October 2021 in an urban community, in Beijing, China. The participants completed the 14-item Fatigue Scale (FS-14), Falls Efficacy Scale International (FES-I), the Short Physical Performance Battery (SPPB) and Fall-Risk Self-Assessment Questionnaire (FRQ) to measure fatigue, falls efficacy, lower limb function and falls risk. The theory of unpleasant symptoms was used as a conceptual framework. Structural equation modeling (SEM) was utilized to test the hypothetical model., Results: The overall fit of final model was found to be satisfactory: χ 2/df = 1.61, CFI = 0.971, TLI = 0.962, RMSEA = 0.049 ( 95% CI 0.030/0.066) and SRMR = 0.023. Fatigue had a direct effect on falls risk (β = 0.559, S.E . = 0.089, 95% CI 0.380/0.731), and it also had indirect effects on falls risk (β = 0.303, S.E . = 0.072, 95% CI 0.173/0.460) through mediating factors. Falls efficacy and lower limb function were the main mediating variables, and there was a chain mediating effect (β = 0.015, S.E . = 0.010, 95% CI 0.003/0.046)., Conclusions: Our study suggests that fatigue can influence falls risk among the elderly in China. There are many mediating paths between fatigue and falls risk. These results may help healthcare professionals to better understand the inherent relationship between fatigue and fall risk that may benefit older adults., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 He, Zhang, Song, Wu and Pi.)

The widespread occurrence of microplastics in the marine environment has drawn global attention because microplastics may impact the populations of marine organisms. As such, aquaculture industry may suffer from microplastic pollution, especially when plastic products are widely used for aquaculture. Here, we assessed the abundance and characteristics (type, size and composition) of microplastics in sediment and typical commercial species (fish, bivalves and shrimps) in an aquaculture site at Xiangshan Bay, which has been operated intensively for decades. Satellite remote sensing images revealed that aquaculture activities were associated with microplastic pollution in sediment, where the microplastics (51-88 items/kg dry weight) were mostly fibres (>94%) and between 500 and 2000 µm. Cellulose was the predominant polymer (60-88% of microplastic composition), followed by polypropylene. Microplastics accumulated in all the commercial species (0.95-2.1 items per individual), where shrimp (Parapenaeopsis hardwickii) had lower potential for microplastic accumulation than the other species. The predominance of fibres and cellulose in the commercial species implies their limited ability to recognize the type and composition of microplastics during ingestion. Given the limited accumulation of microplastics in these typical commercial species even at a productive aquaculture site, we suggest that microplastics may not increase the health risk of consuming seafood and their impacts on commercial species may be less deleterious than previously thought., (Copyright © 2019 Elsevier B.V.

To examine the current situation of patient delay and to identify factors associated with patient delay among women with breast cancer in China.A total of 283 women, aged 23 to 83 years old and with histologically confirmed breast cancer, were investigated in this cross-sectional study. The women were recruited from seven selected hospitals in Sichuan Province, China. Face-to-face interviews using a structured questionnaire were performed.Among the 283 participants, the range of patient delay was 0.2 to 900 days with a median patient delay of 50 days. A total of 35.8% of patients waited ≥90 days to access medical treatment after symptom onset. Binary logistic regression analysis showed that the main predictors of patient delay were knowledge of breast cancer symptoms (OR = 0.716, 95%CI:0.637-0.804, P = .000), external health locus of control (OR = 1.173, 95%CI:1.087-1.266, P = .000), breast self-examination/physical examination (OR = 0.065, 95%CI: 0.007-0.590, P = .015), perceived health competence (OR = 0.873, 95%CI:0.808-0.944, P = .000), family support (OR = 0.911,95%CI:0.847-0.981, P = .013), pain stimulation (OR = 0.191, 95%CI:0.046-0.792, P = .023) and age (OR = 1.028, 95%CI:1.000-1.058, P = .049).These factors explained 41.0% of the variance.Information on the current situation and predictors of patient delay in Chinese women with breast cancer might provide meaning insights into the early diagnosis of breast cancer. The results of this study may help health professionals develop specific clinical practice strategies to reduce patient delay of initial treatment as a way to improve outcomes for women with breast cancer.
