Changes in temperature extremes over China under 1.5 ℃ and 2 ℃ global warming targets

The long-term goal of the 2015 Paris Agreement is to limit global warming to well below 2 ℃above pre-industrial levels and to pursue efforts to limit it to 1.5 ℃. However, for climate mitigation and adaption efforts, further studies are still needed to understand the regional consequences between the two global warming limits. Here we provide an assessment of changes in temperature extremes over China （relative to 1986-2005） at 1.5 ℃ and 2 ℃ warming levels （relative to 1861-1900） by using the 5th phase of the Coupled Model Intercomparison Project （CMIP5） models under three RCP scenarios （RCP2.6, RCP4.5, RCP8.5）. Results show that the increases in mean temperature and temperature extremes over China are greater than that in global mean temperature. With respect to 1986-2005, the temperature of hottest day （TXx） and coldest night （TNn） are projected to increase about 1/1.6 ℃ and 1.1/1.8 ℃, whereas warm days （TX90p） and warm spell duration （WSDI） will increase about 7.5/13.8% and 15/30 d for the 1.5/2 ℃ global warming target, respectively. Under an additional 0.5 ℃ global warming, the projected increases of temperature in warmest day/night and coldest day/night are both more than 0.5 ℃ across almost the whole China. In Northwest China, Northeast China and the Tibetan Plateau, the projected changes are particularly sensitive to the additional 0.5 ℃ global warming, for example, multi-model mean increase in coldest day （TXn） and coldest night （TNn） will be about 2 times higher than a change of 0.5 ℃ global warming. Although the area-averaged changes in temperature extremes are very similar for different scenarios, spatial hotspot still exists, such as in Northwest China and North China, the increases in temperatures are apparently larger in RCP8.5 than that in RCP4.5.

Recent Study of Drag Embedment Plate Anchors in China

Experimental and theoretical studies of drag embedment plate anchors recently carried out in Tianjin University are summarized in this research paper, which involve a series of important topics relevant to the study of drag anchors. The techniques for measuring the trajectory and movement direction of drag anchors in soils, the techniques for measuring the moving embedment point and reverse eatenary shape of the embedded drag line, the penetration mechanism and kinematic behavior of drag anchors, the ultimate embedment depth of drag anchors, the movement direction of the anchor with an arbitrary fluke section, the reverse catenary properties of the embedded drag line, the interaetional properties between drag anchor and installation line, the kinematic model of drag anchors in seabed soils, and the analytical method for predicting the anchor trajectory in soils will all be examined. The present work remarkably reduces the uncertainties in design and analysis of drag embedment plate anchors, and is beneficial to improving the application of this new type of drag anchor in offshore engineering.

Impact of Tourists'Perceived Value on Behavioral Intention for Mega Events:Analysis of Inbound and Domestic Tourists at Shanghai World Expo

Based on the survey data for 2120 inbound and domestic tourists at the Shanghai World Expo,a structural equation model was constructed for the relationship among tourists' perceived value dimensions,behavioral intention and revisit intention.Additionally,the influence of tourists' perceived value dimensions on the behavioral intention and revisit intention was explored.The results show that the utilitarian value and enjoyment value significantly affect the inbound and domestic tourists' behavioral intention,while the convenience value and aesthetic value have no significant influence.The service value only significantly affects the domestic tourists' behavioral intention,and the aesthetic value only significantly affects the inbound tourists' behavioral intention.The utilitarian value,service value and enjoyment value significantly affect the inbound and domestic tourists' revisit intention,while the convenience value only significantly affects the domestic tourists' revisit intention.The utilitarian value is the primary factor affecting the inbound tourists' behavioral intention and revisit intention,and the perceived price has no significant effect on either inbound or domestic tourists' behavioral intention or revisit intention.The study explores the relationships between tourists' perceived value,behavioral intention and revisit intention,analyzes the divergence and causation,theoretically enriches the research field of tourism geography and behavioral geography,and has great practical significance to the sustainable development of mega events in China,including the further development of the Shanghai World Expo.

A Novel Feature-based Method for Sentiment Analysis of Chinese Product Reviews

Sentiment analysis of online reviews and other user generated content is an important research problem for its wide range of applications.In this paper,we propose a feature-based vector model and a novel weighting algorithm for sentiment analysis of Chinese product reviews.Specifically,an opinionated document is modeled by a set of feature-based vectors and corresponding weights.Different from previous work,our model considers modifying relationships between words and contains rich sentiment strength descriptions which are represented by adverbs of degree and punctuations.Dependency parsing is applied to construct the feature vectors.A novel feature weighting algorithm is proposed for supervised sentiment classification based on rich sentiment strength related information.The experimental results demonstrate the effectiveness of the proposed method compared with a state of the art method using term level weighting algorithms.

Stock selection using support vector machine in Chinese securities exchange

The risk and performance of ST stocks are studied.The SVM method is applied on 100 general stocks and 100 ST stocks selected from the website,and a criterion is gotten to select stocks,then the risk of these sample stocks is analysed.In the performance evaluation,the SVM method is also applied on the 100 general stocks and 100 ST stocks according to the return per share,and 57 stocks which are all +1 are selected.Their equally weighted return rate is only-0.02%,but equally weighted return rate of 31 general stocks is 13.23%,that of 26 ST stocks is-96.15%.Naturally,we conclude that ST stocks are unsteady and do not deserve long-term investment.From the Chinese fund website,we know that equally weighted return rate of stock fund in 2004 was-3.3%,so the equally weighted return rate of the selected stocks(except ST stocks)is much higher than that of average return rate.

An Empirical Study on Purchasing Intention of Online Group-buying in China

In recent years, the development of electronic commerce has led to the creation of many new and interesting business models for intemet-based buying, and online group-buying has become an effective form of it. Online group-buying is a model in which consumers collaborate and purchase a good at a discounted price. The purpose of this study is to examine the effect of reputation, price and service on purchasing intention through mediator which is perceived risk. To empirically test the proposed model, a survey was conducted and 140 samples were collected. The result of this study shows price has a significant effect on purchasing intention through perceived risk. This result also shows service and reputation have an insignificant relationship with perceived risk. Therefore, online group-buying retailers should not only focus on making money from the business but also consider how to keep consumers for future business.

DETERMINATION OF ONSET DATE OF THE SOUTH CHINA SEA SUMMER MONSOON IN 2006 USING LARGE-SCALE CIRCULATIONS

Since the South China Sea (SCS) summer monsoon (SCSSM) is pronouncedly featured by abruptly intensified southwesterly and obviously increased precipitation over the SCS,the lower-tropospheric winds and/or convection intensities are widely used to determine the SCSSM onset.The methods can be used successfully in most of the years but not in 2006.Due to the intrusion of Typhoon Chanchu(0601)that year,the usual method of determining SCSSM onset date by utilizing the SCS regional indices is less capable of pinpointing the real onset date.In order to solve the problem,larger-scale situations have to be taken into account.Zonal and meridional circulations would be better to determine the break-out date of SCSSM in 2006.The result indicates that its onset date is May 16.Moreover,similar onset dates for other years can be obtained using various methods,implying that large-scale zonal and meridional circulations can be used as an alternative method for determining the SCSSM onset date.

The Redirection of US Foreign Strategy against the Background of Globalization

American foreign strategy has had strong continuity since World War II despite differences among successive presidents. Donald Trump's 2016 presidential campaign revealed ideas and goals for US strategy and strategy adjustment that differ significantly from those of predecessors. The decline in relative gains and rise in cost for US involvement in globalization are reasons for Trump to redirect US foreign strategy. The relative decrease of both US trade and foreign direct investment in the US, amid security threats and the identity crisis of the American people, has tremendously increased the pricetag for US involvement in globalization.

Anne Frank： The Commemoration of Individual Experiences of the Holocaust

Holocaust memorial sites rarely tell the story of individual fates but rather give attention to the main or larger population groups that were the focus of persecution and extermination during the Nazi Germany twelve years of terror in Europe 1933-45. This essay takes a closer look at one of the most remarkable exemptions of the prevailing memory culture at Holocaust memorials： the sites and events highlighting Anne Frank and her short life in troubled times. Over the past years millions of travelers from all over the world have shown a genuine interest in learning about the life world of their young heroine thus creating what has been termed Anne Frank Tourism. In 2014, 1.2 million people visited the Anne Frank House in Amsterdam： the museum and educational center, the place in hiding where she wrote her now famous and widely read diary. Several other sites connected to the life path of Anne Frank, from her birth place in Frankfurt to the Bergen-Belsen Concentration Camp where her life prematurely ended, have also become part of the mostly young tourists＇ search for Anne Frank＇s life and legacy. With the rising popularity of Anne Frank related sites the management of some of the locales has become more problematic which is discussed in the context of a several museums, centers and historic sites. On a more general note, it is argued here that in recent years the more group oriented commemoration practices at Holocaust sites have given way to a trend of putting individual faces to the victims of the Holocaust. It was, in particular, novels, films and TV productions about the Holocaust that emphasized individual life paths and events and enticed visitation to more personalized sites. Steven Spielberg＇s popular movie Schindler＇s List, for example, contributed to ＂Schindler tourism＂, a form of special interest tourism in Krakow. More and more Holocaust memorial sites have also started to honor outstanding individuals or small groups in resistance and opposition to Nazi Germany. Examples of this are the fighters of the 1943 uprising at the Sobibor death camp and the courageous student members of the ＂White Rose＂ in Munich who stood up to the powers of the time and were executed. In the concluding part the question will be raised of what is the proper approach in the representation of the fate of the victims of Nazi Germany： A personalized approach or a greater focus on an explanation of the ideology and policies behind the rule of terror which may contribute to the visitors＇ better understanding of a complex history？

Features of Seismicity in the Northeastern China Region and Their Relation to the Subduction of the Japan Sea Plate

Based on the analyses of grouped activity features of deep-focus (M≥6.0) and shallow-focus (M S≥5.0) earthquakes in the Northeast China region, the time-space correlation between deep focus “strong earthquake group" and shallow focus “strong earthquake group" have been studied. The study was mainly on the characteristics of earthquake distribution on the collision zone between the west Pacific plate and the Eurasian plate and on its relations to the morphological feature of the western Pacific subduction zone. Moreover, emphasis was laid on analysis of the effect of the west Pacific plate on the seismicity of Eurasian plate. It is shown that in the region where the west Pacific plate subducts at low angles, the seismicity on the plate collision zone is strong, the effect of plate subduction on Eurasian continent is strong too, and the subduction zone is under a state of high compressional stress. However, in the region where the west Pacific plate subducts at high angles, the seismicity along the plate collision zone is weak, the effect of plate subduction on Eurasian continent is weak too, and the tensile stress produced by the subduction zone at depth is enhanced. We therefore propose that the seismicity in the northeast China region will enter an active period of shallow “strong earthquake group" in the future 10 years. In the period, six earthquakes of M S≥5.0 may occur. Therefore, the work of earthquake monitoring and prediction in this region shall be strengthened.

Using Statistical Learning Algorithms in Regional Landslide Susceptibility Zonation with Limited Landslide Field Data

Regional Landslide Susceptibility Zonation(LSZ) is always challenged by the available amount of field data, especially in southwestern China where large mountainous areas and limited field information coincide. Statistical learning algorithms are believed to be superior to traditional statistical algorithms for their data adaptability. The aim of the paper is to evaluate how statistical learning algorithms perform on regional LSZ with limited field data. The focus is on three statistical learning algorithms, Logistic Regression(LR), Artificial Neural Networks(ANN) and Support Vector Machine(SVM). Hanzhong city, a landslide prone area in southwestern China is taken as a study case. Nine environmental factors are selected as inputs. The accuracies of the resulting LSZ maps are evaluated through landslide density analysis(LDA), receiver operating characteristic(ROC) curves and Kappa index statistics. The dependence of the algorithm on the size of field samples is examined by varying the sizes of the training set. The SVM has proven to be the most accurate and the most stable algorithm at small training set sizes and on all known landslide sizes. The accuracy of SVM shows a steadilyincreasing trend and reaches a high level at a small size of the training set, while accuracies of LR and ANN algorithms show distinct fluctuations. The geomorphological interpretations confirm the strength of SVM on all landslide sizes. Our results show that the strengths of SVM in generalization capability and model robustness make it an appropriate and efficient tool for regional LSZ with limited landslide field samples.

Changes in spatial variations of sap flow in Korean pine trees due to environmental factors and their effects on estimates of stand transpiration

It is difficult to scale up measurements of the sap flux density(J_S) for the characterization of tree or stand transpiration(E) due to spatial variations in J_S and their temporal changes.To assess spatial variations in the sap flux density of Korean pine(Pinus koraiensis) and their effects on E estimates,we measured the J_S using Granier-type sensors.Within trees,the J_S decreased exponentially with the radial depth,and the J_S of the east aspects were higher than those of the west aspects.Among trees,there was a positive relationship between J_S and the tree diameter at breast height,and this positive relationship became stronger as the transpiration demand increased.The spatial variations that caused large errors in E estimates(i.e.,up to 110.8 % when radial variation was ignored) had varied systematically with environmental factors systematic characteristics in relation to environmental factors.However,changes in these variations did not generate substantial errors in the E estimates.For our study periods,the differences in the daily E(E_D) calculated by ignoring radial,azimuthal and tree-to-tree variations and the measured E_D were fairly constant,especially when the daily vapor pressure deficit(D_D)was higher than 0.6 k Pa.These results imply that the effect of spatial variations changes on sap flow can be a minor source of error compared with spatial variations(radial,azimuthal and tree-to-tree variations) when considering E estimates.
