Today's Linzhou has Undergone Great Changes

LINZHOU City, which was previously called Linxian County in Henan Province, is famous for the Red Flag Canal built in the 1960s. Much has changed since then and the "Spirit of Red Flag Canal" has new meaning. Pursuing Brighter Prospects Since the Red Flag Canal was built,

New Trends in International Energy Security in the Context of Profound Changes Unseen in a Century

Major changes such as the pandemic, games among great powers, and the Ukraine crisis alongside scientific and technological progress, economic transformation, social change, and cultural development have led to new features and trends in the international energy field. Historic fluctuations in international energy prices and adjustments in energy relations have taken place in the past two years. The energy system has fallen into disorder and discomfort;volatility in the energy market has triggered a strong domino effect, and major countries have taken unprecedented measures to address it. These changes have pushed international energy politics to a new development track. In a certain period of time in the future, the political and security aspects of energy will once again come to the fore. The long-term nature and complexity of the energy transition have become more obvious. In international energy politics, turbulence and uncertainty will be the new normal. A new binary opposition may emerge in the international energy landscape as well, with constant changes taking place in the connotation and extension of energy security. Academic and strategic circles should think deeply about how to dialectically discuss the relation between energy transition and the major changes of a scale unseen in a century, energy transition and energy security, and geopolitics and energy politics, among others, and consider the integration of development and security and the realization of common energy security as important principles for operating and developing energy strategies and promoting global energy governance.

Water storage changes in North America retrieved from GRACE gravity and GPS data

As global warming continues,the monitoring of changes in terrestrial water storage becomes increasingly important since it plays a critical role in understanding global change and water resource management.In North America as elsewhere in the world,changes in water resources strongly impact agriculture and animal husbandry.From a combination of Gravity Recovery and Climate Experiment（GRACE） gravity and Global Positioning System（GPS） data,it is recently found that water storage from August,2002 to March,2011 recovered after the extreme Canadian Prairies drought between 1999 and 2005.In this paper,we use GRACE monthly gravity data of Release 5 to track the water storage change from August,2002 to June,2014.In Canadian Prairies and the Great Lakes areas,the total water storage is found to have increased during the last decade by a rate of 73.8 ± 14.5 Gt/a,which is larger than that found in the previous study due to the longer time span of GRACE observations used and the reduction of the leakage error.We also find a long term decrease of water storage at a rate of-12.0 ± 4.2 Gt/a in Ungava Peninsula,possibly due to permafrost degradation and less snow accumulation during the winter in the region.In addition,the effect of total mass gain in the surveyed area,on present-day sea level,amounts to-0.18 mm/a,and thus should be taken into account in studies of global sea level change.

Goce derived geoid changes before the Pisagua 2014 earthquake

The analysis of space-time surface deformation during earthquakes reveals the variable state of stress that occurs at deep crustal levels, and this information can be used to better understand the seismic cycle. Understanding the possible mechanisms that produce earthquake precursors is a key issue for earthquake prediction. In the last years, modern geodesy can map the degree of seismic coupling during the interseismic period, as well as the coseismic and postseismic slip for great earthquakes along subduction zones. Earthquakes usually occur due to mass transfer and consequent gravity variations, where these changes have been monitored for intraplate earthquakes by means of terrestrial gravity measurements. When stresses and correspondent rupture areas are large, affecting hundreds of thousands of square kilometres（as occurs in some segments along plate interface zones）, satellite gravimetry data become relevant. This is due to the higher spatial resolution of this type of data when compared to terrestrial data, and also due to their homogeneous precision and availability across the whole Earth.Satellite gravity missions as GOCE can map the Earth gravity field with unprecedented precision and resolution. We mapped geoid changes from two GOCE satellite models obtained by the direct approach,which combines data from other gravity missions as GRACE and LAGEOS regarding their best characteristics. The results show that the geoid height diminished from a year to five months before the main seismic event in the region where maximum slip occurred after the Pisagua Mw = 8.2 great megathrust earthquake. This diminution is interpreted as accelerated inland-directed interseismic mass transfer before the earthquake, coinciding with the intermediate degree of seismic coupling reported in the region. We highlight the advantage of satellite data for modelling surficial deformation related to preseismic displacements. This deformation, combined to geodetical and seismological data, could be useful for delimiting and monitoring areas of higher seismic hazard potential.

Research on the construction path of the megacity from the perspective of Nudge Theory:Empirical evidence of the“Park City”construction in Chengdu Tianfu New Area

The transformation of Chengdu Tianfu New Area,a state-level new district,from the first site of constructing the“Park City”to the representative of the“Park City”,contains a unique path of“Chinese Style Governance”.To expand the diverse paths of constructing megacities,the current research references the nudge theory of behavioral science,adopts the extended case method,and takes Chengdu Tianfu New Area as a typical case to summarize the“nudge”path of“Party City”construction.The study found that the government achieves the lock-in effect by the priming mechanism and uses the nudge strategy of improving environment and guiding public opinion,thereby helping the people make free choices.It realizes the framework effect by the salience mechanism and uses the strategies of highlighting key information and optimizing information delivery methods,which directly affects the behavior of the public.It achieves the commitment effect by the comparison mechanism,including the horizontal comparison and vertical comparison strategies,and gradually realizes the policy goals.It realizes the social norm effect by the imitation mechanism and uses the strategies of creating peer pressure and playing celebrity effect,which in turn influence people’s choices.With the help of the“nudging”mechanism,the construction of the park city has realized the interactive cycle of“government output-citizen feedback”and achieved the goal of“making great change through small actions”.As a new behavioral intervention tool,“nudging”provides an alternative explanation for the construction of the park city in Tianfu New Area and opens up new ideas for the construction of megacities.This study concludes that the construction of megacities can achieve the goal of“common return”through different ways and provides practical inspiration for future urban construction.

European Strategy and Its Impacts

Facing major changes unseen in a century,including challenges to Western values and hegemony and western Europe’s potential marginalization,the European Union has not yet solidified its strategic response.Trends taking shape in domestic and foreign policies include defensiveness and security worries,calls for greater independence and global influence,and a pursuit of contraction while strengthening border safety.Europe is considering a“third way”that would succeed among competing parameters,present and future.With China surpassing the US to become Europe’s largest trading partner in 2020,Europe is at a decision point that will impact both its development and China-EU relations in complex ways.
