1Chinese progress in geomorphometry显示文摘Geomorphometry,the science of digital terrain analysis(DTA),is an important focus of research in both geomorphology and geographical information science(GIS).Given that 70% of China is mountainous,geomorphological research is popular among Chinese scholars,and the development of GIS over the last 30 years has led to significant advances in geomorphometric research.In this paper,we review Chinese progress in geomorphometry based on the published literature.There are three major areas of progress:digital terrain modelling methods,DTA methods,and applications of digital terrain models(DTMs).First,traditional vector-and raster-based terrain modelling methods,including the assessment of uncertainty,have received widespread attention.New terrain modelling methods such as unified raster and vector,high-fidelity,and real-time dynamic geographical scene modelling have also attracted research attention and are now a major focus of digital terrain modelling research.Second,in addition to the popular DTA methods based on topographical derivatives,geomorphological features,and hydrological factors extracted from DTMs,DTA methods have been extended to include analyses of the structure of underlying strata,ocean surface features and even socioeconomic spatial structures.Third,DTMs have been applied to fields including global climate change,analysis of various typical regions,lunar surface and other related fields.Clearly,Chinese scholars have made significant progress in geomorphometry.Chinese scholars have had the greatest international impact in areas including high-fidelity digital terrain modelling and DTM-based regional geomorphological analysis,particularly in the Loess Plateau and the Tibetan Plateau regions.LV Guonian XIONG Liyang CHEN Min TANG Guoan SHENG Yehua LIU Xuejun SONG Zhiyao LU Yuqi YU Zhaoyuan ZHANG Ka WANG Meizhen 2017Journal of Geographical Sciences2017,27,11:14

5Pay-it-forward gonorrhea and chlamydia testing among men who have sex with men in China:a study protocol for a three-arm cluster randomized controlled trial显示文摘Background:Gonorrhea and chlamydia testing rates are poor among Chinese men who have sex with men(MSM).A quasi-experimental study suggested that a pay-it-forward strategy increased dual gonorrhea/chlamydia testing among MSM.Pay-it-forward offers an individual a gift(e.g.,a free test)and then asks the same person if they would like to give a gift to another person.This article reports the protocol of a randomized controlled trial to evaluate dual gonorrhea/chlamydia test uptake and other outcomes among MSM in three arms-a pay-it-forward arm,a pay-what-you-want arm,and a standard of care arm.Methods:Three hundred MSM will be recruited at three HIV testing sites in Guangzhou and Beijing.Testing sites include two hospital-based MSM sexually transmitted diseases clinics and one MSM community-based organization.Eligible participants will be born biologically male,aged 16 years or older,reporting previous anal sex with another man,having never participated in the pay-it-forward program,without previous gonorrhea and chlamydia testing in the past 12 months,and residing in China.Following a cluster randomized design,every cluster of ten participants will be randomly allocated into one of three arms:(1)a pay-it-forward arm in which men are offered free gonorrhea and chlamydia testing and then asked whether they would like to donate('pay it forward')toward testing for future testers;(2)a pay-what-you-want arm in which men are offered free testing and told to decide how much to pay after receiving the test;(3)a standard of care arm in which men can pay the full price for dual gonorrhoea and chlamydia testing.The primary outcome is dual gonorrhoea/chlamydia testing as verified by administrative records.Secondary outcomes include incremental cost per test,incremental cost per diagnosis,community connectedness,and social cohesion.Primary outcome will be calculated for each arm using intention-to-treat and compared using one-sided 95%confidence intervals with a margin of 20%increase defined as superiority.Discussion:This study will examine the pay-it-forward strategy in comparison to the standard of care in improving test uptake for gonorrhea and chlamydia.We will leverage the cluster randomized controlled trial to provide scientific evidence on the potential effect of pay-it-forward.Findings from this study will shed light on novel intervention methods for increasing preventive health service utilization and innovate ways to finance it among communities.Trial registration:ClinicalTrials.gov,NCT03741725.Registered on 12 November 2018.Tiange P.Zhang Fan Yang Weiming Tang Marcus Alexander Laura Forastiere Navin Kumar Katherine Li Fei Zou Ligang Yang Guodong Mi Yehua Wang Wenting Huang Amy Lee Weizan Zhu Peter Vickerman Dan Wu Bin Yang Nicholas A.Christakis Joseph D.Tucker 2019Infectious Diseases of Poverty2019,8,4:1
