Countries around the world generally recognize the strategic value of cyberspace.Information and communications technology(ICT)has become one of the key elements in the economic development,national security and comprehensive strength of countries.It has also become a key battleground of major-power rivalry.China has always attached great importance to developing and governing the cyberspace since it was connected to the internet nearly 30 years ago.The country also recognizes the international importance of cyberspace governance,particularly focusing on its increasingly unbalanced development,inadequate rules and inequitable order,and is committed to addressing the deficit of global cyberspace governance. 展开更多

The great-power rivalry,the once-in-a-century pandemic and the Ukraine crisis have profoundly altered the EU’s worldview,and the EU’s Africa policy has experienced a reorientation in this context,which refocuses on long-term strategic goals and serves its geopolitical shift in great-power competition.The EU wishes to move beyond the“donor-recipient”relationship and forge a reciprocal,equal,and balanced partnership with Africa,but the geopolitical shift in its strategy for Africa under the Cold War mentality is at odds with the goal,with deep-seated contradictions exposed in the process of policy reorientation. 展开更多

Bone biomaterials have been increasingly used to reconstruct maxillary atrophic ridges.Thus,the aim of this study was to evaluate bone reconstruction in the maxilla using a homologous cortico-cancellous FFB(lyophilized)graft and verify its reliability.Eight individuals were included from 2014 to 2018.The first surgery was performed to install homologous bone blocks in the maxilla.The period of the second intervention varied between 5 months and 15 days to 11 months(≈7.93 months).The biopsies were taken from the central region of the matured graft during the surgery for implant placement.All patients presented clinical and radiographic conditions for the installation of dental implants.There was a 100%of survival rate.The histological assessment showed that the homologous block bone graft was an osteoconductive biomaterial,with connective tissue present,and newly formed bone juxtaposed on its surface.There were bone trabeculae with osteocytes and active osteoblasts with connective tissue in the mineralization process;the remodeling process can be found through the reverse lines.A limited focus of necrosis with fibrosis was detected,with small resorption and areas of inflammatory infiltrate,but without clinical significance.The homologous block bone graft can be considered a feasible option to substitute the autogenous bone graft(gold standard),with predictable clinical and favorable histological results.The patients had a shorter surgical period,low morbidity,and an unlimited amount of biomaterial available at an accessible cost. 展开更多

The political essence of Russian conservatism is to respect the historical tradition and take a development path aligned with Russia's national conditions.Since Putin came to power,Russian conservatism has developed into the mainstream official ideology,becoming the core concept of Russia's current domestic and foreign policies.Russian conservatism is not only the guiding principle of Russia's national foreign policy,but it is also the moral banner of Russia's diplomacy,which reflects its foreign cognition and value system.Under the guidance of conservatism,Russia's foreign policy has distinct offensive features,and Russia has intensified its efforts to counter the liberal international order dominated by the West.After the escalation of the Ukraine crisis,the status of conservatism as Russia's mainstream ideology has been further consolidated,exerting a comprehensive influence on foreign policy.Against the background of extreme sanctions and isolation from the United States and the West,Russia has turned its diplomatic attention to non-Western countries,hoping to build a new international order. 展开更多

US President Joe Biden has quickly adjusted the country’s climate strategy upon taking office.He issued a series of executive orders to advance his ambitious new climate agenda and adopted a whole-of-government approach with a multi-faceted package of climate policies.The Biden administration has demonstrated a proactive stance toward climate governance by putting forward three major objectives:achieving a 50-52 percent reduction from 2005 levels in economy-wide net greenhouse gas pollution in 2030,a carbon pollution-free power sector by 2035,and net zero emissions economy no later than 2050.While putting the climate crisis squarely at the center of US foreign policy and national security,1 the Biden administration has taken climate diplomatic actions at global,regional,and bilateral levels.It announced the US return to the Paris Agreement and held the Leaders Summit on Climate.Through committed and globally significant moves to tackle climate change,the US is trying to reassert its leadership on the global climate agenda and enhance its international competitiveness.More than two years into its implementation,the Biden administration’s climate diplomacy has left its imprint on global climate governance and low-carbon transition. 展开更多

In the report of the 20th National Congress of the Communist Party of China,“Our world,our times,and history are changing in ways like never before...All of this is posing unprecedented challenges for human society.The world is standing at the crossroad of history,and everyone must work together to map out its future.”1 Europe likewise faces the zeitenwende moment.Europe’s perceptions of the world have changed with the twin shock of the COVID-19 pandemic and the Ukraine crisis.The evolving new world order and the necessary adjustments of its self-perceptions,policy goals,and implementation paths have accelerated.Currently,Europe is experiencing the transition from the post-Lisbon Treaty era to the post-Ukraine crisis period.In the near future,Sino-Europe relations will act as an important factor in the transformation of Europe and become a major factor in shaping the future regional and world order.Although their perceptions and behaviors of the“Zeitenwende”are different,China and Europe must work together and play a positive and constructive role in building a new type of international relations and working out a new framework of major power relations that is stable and balanced. 展开更多

In Australia,the Labor Party has been very active diplomatically since it came to power,making multiple positive gestures to repair the relations with China,which were seriously impacted under the previous Liberal-National Coalition government.However,its policy toward China has not improved as much as some expected.On the contrary,the senior leadership in the Labor Party remains cautious in its stance on China and has repeatedly stressed that its position on China is the same as that of the Coalition.This article will analyze the trends and logic of the Australian Labor Party’s policy toward China by examining the party’s statements and measures during and after the 2022 federal election,to help better understand the trajectory of China-Australia relations. 展开更多
