si RNA helicase-regulated processing of the Synechocystis rimO-crhR operon results in differential cistron expression and accumulation of two sRNAs [Gene Regulation] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The arrangement of functionally-related genes in operons is a fundamental element of how genetic information is organized in prokaryotes. This organization ensures coordinated gene expression by co-transcription. Often, however, alternative genetic responses to specific stress conditions demand the discoordination of operon expression. During cold temperature stress, accumulation of the gene encoding the sole Asp–Glu–Ala–Asp (DEAD)-box RNA helicase in Synechocystis sp. PCC 6803, crhR (slr0083), increases 15-fold. Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.

Read online Download PDF Security and Prosperity in Asia Cover Image.jpg Singapore skyline at sunset, 2016. Photo: Getty Images. About the ConferenceAt a time of geopolitical uncertainty and with multilateralism under pressure, this conference brought together diverse actors to explore the evolving role of international law on critical security and economic issues in the Asia-Pacific. From trade agreements to deep-sea mining, cyberwarfare to territorial disputes, the breadth of the discussion illustrated the growing reach of international law in the region.Hosted by the International Law Programme and the Asia-Pacific Programme at Chatham House on 27 March 2019, the conference focused on three themes: trade and investment, maritime security and governance, and emerging security challenges. What trends are emerging in terms of engagement with international law in the region, and how can international standards play a greater role in encouraging collaboration and reducing tensions? And, with the eastward shift in geopolitical power, how will Asia-Pacific states shape the future of international law?

si Non-traditional security cooperation between China and south-east Asia: implications for Indo-Pacific geopolitics By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:17:30 +0000 8 January 2020 , Volume 96, Number 1 Read online Xue Gong The ‘free and open Indo-Pacific’ (FOIP) strategy, actively promoted by the United States with support from its allies and partners, is a significant geopolitical response to China's growing power and expanding influence in Asia and beyond. Beijing has adopted various new strategies to cope with the challenges related to FOIP. One of these strategies is to secure a robust relationship with south-east Asia in order to make these regional states either neutral to or less supportive of the Indo-Pacific vision. In addition to economic statecraft and soft power, Beijing believes that it can also tap into the domain of non-traditional security (NTS) to strengthen relations with this region to position itself better in the intensifying regional geopolitical competition. The article addresses the following question: what is the impact of China's NTS cooperation with south-east Asia on Beijing's geopolitical rivalry with other major powers in the Indo-Pacific region? The article argues that China's NTS cooperation with south-east Asian countries may help China maintain its geopolitical standing in the region, but it is unlikely to lead to any dramatic increase of China's strategic influence in the region. This essentially means that Beijing may be able to prevent ASEAN or most ASEAN member states from lending substantive and strong support to the Indo-Pacific construct, but it will not be able to stop ASEAN states from supporting some elements of the FOIP.

si Evasive balancing: India's unviable Indo-Pacific strategy By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:37:22 +0000 8 January 2020 , Volume 96, Number 1 Read online Rajesh Rajagopalan India has adopted the Indo-Pacific concept with uncharacteristic speed. This article examines India's Indo-Pacific strategy, which evolved out of its earlier ‘Look East’ and ‘Act East’ policies but is much more focused on strategic concerns than on trade or connectivity. As such, the strategy is subset of its China policy, and includes contradictory elements of balancing China by building partnerships with the United States as well as with regional powers, while simultaneously pursuing a reassurance strategy to convince Beijing that India is not really balancing China. The combination of these contradictory elements is characterized as evasive balancing, which is a more useful concept than either pure balancing or hedging for understanding the policies of India and of many other countries in the region that are trying to manage China's rise. However, reassurance strategies rarely work and the combination of balancing and reassurance is even less likely to be viable. Full Article
si Is Australia's Indo-Pacific strategy an illusion? By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:39:40 +0000 8 January 2020 , Volume 96, Number 1 Read online Brendan Taylor Australia has been among the most prominent advocates of the increasingly popular Indo-Pacific concept. This article argues that Canberra's enthusiasm for the concept stems from its appeal to the two dominant traditions of Australian foreign policy—a ‘dependent ally’ tradition and a ‘middle power’ approach. While these two traditions are typically seen as being in tension, the Indo-Pacific concept provides a rare point of convergence between them. The article begins by outlining the appeal of the Indo-Pacific concept to each of these traditions. Using a case-study of recent Australian policy toward the South China Sea disputes, however, the article then demonstrates that Australia has in practice implemented its stated Indo-Pacific strategy far less consistently than its very vocal support would appear to suggest. This disjuncture is attributed to the growing influence of a third, generally understudied, ‘pragmatic’ Australian foreign policy tradition. Because Australia has been such a prominent champion of the Indo-Pacific concept, the article concludes that this divergence between the rhetoric and the reality of Australia's Indo-Pacific strategy threatens to have a negative impact on the concept's broader international appeal and sustainability, particularly among Australia's south-east Asian neighbours.

si Indonesia and the ASEAN outlook on the Indo-Pacific By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:44:49 +0000 8 January 2020 , Volume 96, Number 1 Read online Dewi Fortuna Anwar Indonesia has taken a leadership role within the Association of Southeast Asian Nations (ASEAN) in drafting a common outlook on the Indo-Pacific concept. The widening of Indonesia's geostrategic canvas from the Asia–Pacific to the Indo-Pacific is in line with President Joko Widodo's intent to make Indonesia a Global Maritime Fulcrum (GMF). In view of the rivalry between the US and China and the emergence of various Indo-Pacific initiatives from other countries, Indonesia believes that ASEAN must try to maintain its centrality. The draft of Indonesia's perspective for an ASEAN outlook on the Indo-Pacific: towards a peaceful, prosperous, and inclusive region was submitted for considerations by ASEAN, and after 18 months of intensive lobbying by Indonesia the concept was finally adopted at the ASEAN Summit in June 2019. The ASEAN outlook promotes the principles of openness, inclusiveness, transparency, respect for international law and ASEAN centrality in the Indo-Pacific region. It proposes a building-block approach, seeking commonalities between existing regional initiatives in which ASEAN-led mechanisms will act as a fulcrum for both norm-setting and concrete cooperation. Rather than creating a new regional architecture, the East Asia Summit (EAS) is proposed as the platform for advancing the Indo-Pacific discourse and cooperation. Indonesia's ASEAN outlook on the Indo-Pacific marks its renewed foreign policy activism as a middle power and underlines the continuing importance that Indonesia places on ASEAN as the cornerstone of its foreign policy, emphasising ASEAN's centrality as the primary vehicle for managing relations with the major powers in the Indo-Pacific region.

si Consigned to hedge: south-east Asia and America's ‘free and open Indo-Pacific’ strategy By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:47:11 +0000 8 January 2020 , Volume 96, Number 1 Read online See Seng Tan This article assesses how south-east Asian countries and the Association of Southeast Asian Nations (ASEAN) have responded to the ‘free and open Indo-Pacific’ (FOIP) strategies promoted by the United States and the other countries in the Quadrilateral Security Dialogue (the ‘Quad’: US, Japan, Australia and India). Their nuanced ripostes imply a persistent commitment to hedging and shifting limited alignments in the face of growing great rivalry and the lack of a clear FOIP vision among Quad members. In the face of external pressure to take sides, the ASEAN states are likely to keep hedging through working selectively with China and the United States. Given the United States' apparent preference to balance China and Trump's disregard for multilateralism, ASEAN's ability to maintain its centrality in the evolving regional architecture is in doubt—despite the Quad countries' (belated) accommodation of ASEAN in their FOIP strategies. However, the success of the US strategy depends on Washington's ability to build and sustain the requisite coalition to balance Beijing. ASEAN has undertaken efforts to enhance bilateral security collaboration with China and the United States respectively. In doing so, ASEAN is arguably seeking to informally redefine its centrality in an era of Great Power discord and its ramifications for multilateralism. Full Article
si Developmental peace in east Asia and its implications for the Indo-Pacific By feedproxy.google.com Published On :: Wed, 08 Jan 2020 12:01:42 +0000 8 January 2020 , Volume 96, Number 1 Read online Ling Wei This article adopts a constructive approach to examining the problem of the Indo-Pacific construct. Through reflection on the east Asian experience, it proposes an analytical framework of developmental peace as a constellation of international practices, which means that the more economic development is prioritized by states in regional processes, the more likely it is that a sustainable peace will be achieved. States participating in regional integration comprise a community of practice. On the basis of a shared understanding that development is of overriding importance and underpins security and state legitimacy, the community takes economic development as the anchoring practice; this practice embodies and enacts constitutive rules and fundamental norms for a broader set of practices in regional processes, such as peaceful coexistence and non-interference. The more economic development is prioritized on domestic and regional agendas, the more likely it is that conflicts in the security realm will be relaxed or even resolved to protect security interests. The author draws some useful implications from the developmental peace in east Asia for the Indo-Pacific construct, among which the most important include building shared understandings on the prioritization of economic development, taking advantage of the Regional Comprehensive Economic Partnership (RCEP), Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Asian Infrastructure Investment Bank, and using the code of conduct process as a vehicle and best practice to facilitate rule-making for the maritime order. Finally, the author briefly discusses the contributions of the study and limitations of the model. Full Article

si Asian States Must Rethink Their Approach to Digital Governance By feedproxy.google.com Published On :: Fri, 17 Jan 2020 14:27:22 +0000 17 January 2020 Vasuki Shastry Associate Fellow, Asia-Pacific Programme @vshastry LinkedIn Too many governments in the region are focusing on control and surveillance instead of citizens’ rights. 2020-01-17-KashInt.jpg Kashmiri students use the internet at a tourist reception centre in Srinagar, after internet facilities were suspended across the region in December 2019. Photo: Getty Images. Asia’s political class learnt many lessons on digital governance in 2019, not all of them positive.The prolonged protests in Hong Kong and India, led by disaffected young citizenry and enabled by social media tools, powerfully demonstrated how things could spiral out of control when the virtual and the real streets come together.Not surprisingly, governments across the region are taking a step back. Instead of placing the citizen at the heart of digital public policy – with privacy, trust, security and inclusion as drivers of digital governance – Asian governments are focusing instead on surveillance and command and control, which contradicts the spirit of a decentralized Internet and undermines citizen’s rights.Asia’s digital governance is fragmenting from the global norm and morphing into two platforms with remarkably similar characteristics.One is a China-driven model aptly called the Great Firewall where surveillance of citizens is an explicit objective and any external material deemed to be subversive is kept out. A complementary model has also emerged more recently, which can best be described as China-light, which seeks to emulate the control aspects of the Great Firewall.There are of course overlaps between emulators of the China model (this list includes Vietnam, Myanmar, Cambodia and Laos) and those pursuing China-light (Singapore, India, Indonesia, Bangladesh, Sri Lanka, the Philippines, Thailand and Malaysia). A common thread running through these two approaches, which differ only in intensity and scope, is the belief that the state is best positioned to police social media and protect the rights of citizens.This was not how it was supposed to be. A decade ago, Asian political leaders spoke about the virtues of an open internet. Such talk has faded, and a narrowing of Asia’s digital space is taking place against a backdrop of an intensifying trade war between America and China, where regional supply chains run the risk of a decoupling into distinct Sino and American spheres, upending Asia’s durable economic model of the past few decades.Digital fragmentation in the world’s fastest growing region, with five G20 members, will complicate efforts to build global governance and standards.Asia’s digital landscapeAsian governments, including democratic ones, have developed an unhealthy obsession with what their citizens are up to on a daily basis. Their solution is round-the-clock monitoring in cities and towns, powered by new surveillance technologies.Name tagging and facial recognition to track movement of citizens has become pervasive across the region, with China emerging as the preferred source of technology, knowledge, and techniques. While India’s Supreme Court has ruled that privacy is a fundamental right, translating this into concrete citizen’s protections will be difficult with the Modi government eager to emulate China’s approach.Asian governments are also following China in requiring that their citizen’s data be housed within national borders and are rebelling against the established practice of data offshoring.In the post-Snowden era and amidst increasing cyber risks, there are rational national security reasons for why governments may want to ring-fence customer data within national boundaries. However, Asian governments are paying little or no attention to how companies are using customer data within national boundaries, with widespread abuses going unchecked.Global standards are still evolving and there is a strong case here for a uniform regional approach, perhaps via ASEAN or APEC, on standards governing customer privacy, payments, data collection and handling. Big tech companies and platforms operate across much of Asia and a regional approach will curb their current instinct of conducting regulatory arbitrage.There is a genuine problem in Asia, as elsewhere in the world, with the proliferation of fake news and extremism. But instead of addressing the source of this problem, governments are clamping down by generously expanding the definition of fake news (Singapore) or by shutting down the internet altogether (India, Sri Lanka, and China being serial offenders).As disseminators of news of all stripes, including the fake variant, the big tech firms have a primary responsibility in policing their platforms. However, the regulatory capacity of many Asian governments to monitor this is weak and in crisis situations, governments prefer to shut the pipes altogether.Digitalization of course is not all about surveillance and holds the promise of driving inclusion. There is considerable hype within Asia on the promise of fintech as an enabler of this inclusion.Hong Kong and Singapore are licensing new digital banks, India’s UPI (unified payments interface) is reducing friction in domestic payments and China’s BAT companies (Baidu, Alibaba, Tencent) are disrupting traditional commerce and payments, and seeking to expand in the region.However, there is an elite focus in many of these initiatives, with the target market being the region’s rising middle class rather than those at the bottom of the income ladder. Making fintech work for all will require micro-initiatives with the support of NGOs, local governments and small enterprises, with the objective of digitalizing microfinance.Here developing Asia will again benefit from learning from each other and in building regional approaches. India’s Aadhar for example, with appropriate security safeguards, is a model for Asia in terms of building digital identity.Given differing regional and national objectives, it is difficult to imagine a global accord for digital governance any time soon. However, by signing on to the Regional Comprehensive Economic Partnership (RCEP) and the Comprehensive and Progressive Agreement for Transpacific Partnership (CPTPP, the successor to the TPP), Asia has consistently demonstrated its leadership in trade and regional governance.This is why the region needs to come together to ensure that the promise and potential of digitalization flows evenly and equitably to the region, with the region’s 3.8 billion citizens at the heart, rather than at the margins of sensible public policy.

si Network Power in the Asia-Pacific: Making Sense of the New Regionalism and Opportunities for Cooperation By feedproxy.google.com Published On :: Fri, 17 Jan 2020 16:00:01 +0000 Research Event 7 February 2020 - 9:45am to 5:30pm Chatham House | 10 St James's Square | London | SW1Y 4LE Agenda - Network Power in the Asia-Pacific.pdfpdf | 118.01 KB The Asia-Pacific region continues to increase in geopolitical and geoeconomic importance. The rise of China and tensions with the US are affecting bilateral relationships and traditional alliances in the region. Whether seen from the perspective of the Quad – Australia, India, Japan and the US – or the Indo-Pacific concept embraced by a wide range of countries but with no shared consensus on scope and objectives or with ASEAN who insists on the importance of its own centrality, the region is redefining and reconceptualising itself.With a diverse range of initiatives – including the Regional Comprehensive Economic Partnership (RCEP) and Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) – there are a plethora of regional agreements and institutional groupings that add further complexity.As the Bretton Woods architecture continues to be dominated by Western powers, China is also spearheading parallel governance initiatives such as the Asian Infrastructure Investment Bank (AIIB), the Belt and Road Initiative and the Shanghai Cooperation Organization (SCO) as a means of enhancing its geopolitical and geoeconomic influence.This one-day conference will focus on how such networks and alliances have been built, and sustained, in the Asia-Pacific region. In order to understand how new regional initiatives might open up opportunities for new forms of international cooperation, the conference will focus on the themes of cyber-technology and innovation, sustainable development and mitigating the impacts of climate change and new infrastructure initiatives. It will assess whether there is a zero-sum conflict between competing networks and agendas or whether a common approach can be developed.

Photo: Getty Images. The decision by the International Court of Justice (ICJ) that Myanmar should take all measures available to prevent acts of genocide against the persecuted Rohingya minority is truly ground-breaking. The case shows how small states can play an important role in upholding international law and holding other states accountable. The Gambia, acting with the support of the Organization of Islamic Cooperation, skilfully used Article IX of the Genocide Convention, which allows for a state party to the convention to pursue cases against another state party where it is felt there has been a dispute regarding the ‘interpretation, application or fulfilment’ of the convention.Seventeen states have entered reservations against this specific provision but Myanmar is not one of them. It was on this basis that The Gambia was able to take its case to the ICJ. This exciting development expands the possibilities of international accountability at the state-to-state level.But it should be noted that the current ruling is focused on provisional measures – the central case could still take years to conclude. There is still a long road ahead on the court determining whether the Myanmar authorities committed acts of genocide.And, while the decision was unanimous and binding, the ICJ cannot enforce its ruling. Myanmar has shown itself resistant to international criticism and there is a real risk they will fail to comply.One way forward, should Myanmar not respect the ruling, is that the UN Security Council could agree a resolution to compel action. However, it seems unlikely that China would ever vote for such a resolution, given its strong stance on non-intervention and its economic interests in the country. Full Article

A tumultuous 2019 saw the country fighting an economic slowdown coupled with an increasingly hostile international environment. As authorities take assertive steps to contain the virus, the emergency has - at least temporarily - disrupted global trade and supply chains, depressed asset prices and forced multinational businesses to make consequential decisions with limited information. Against this backdrop, panellists reflect on the country’s nascent economic transition from 2020 onward. What has been China’s progress towards a sustainable innovation-led economy so far?

si Asia’s Internet Shutdowns Threaten the Right to Digital Access By feedproxy.google.com Published On :: Tue, 18 Feb 2020 16:32:18 +0000 18 February 2020 Vasuki Shastry Associate Fellow, Asia-Pacific Programme @vshastry LinkedIn Internet shutdowns by Asian governments are curbing their citizens’ space for debate and tougher global regulation is needed, writes Vasuki Shastry. 2020-02-18-Kashmir-Internet.jpg People look at their mobile phones after authorities restored low speed mobile internet services in Kashmir Valley on 25 January 2020. Photo: Getty Images. Internet shutdowns in Asia have become frequent and persistent, an ominous sign of shrinking public space for debate and discourse. The shutdowns have become an irresistible option for governments of all stripes and ideological affiliations. Democratic India, Sri Lanka, Indonesia and the Philippines are prodigious offenders. So are Asia’s more repressive regimes, notably China.In their defence, governments have offered real and imagined threats to national security as reasons for shutting down the pipes. It is useful to examine these claims as well as to objectively frame the issue. Are internet shutdowns in Asia legitimate and can be defended and explained as threats to national security? Or should we take a broader approach where international law, norms, values, rights and indeed economic stability could be invoked to curb this invidious practice?Let’s start with the shutdown in Kashmir, where Indian authorities clamped down on internet access for a straight 165 days, described by rights group Access Now as the ‘longest shutdown ever in a democracy’. The Kashmir Chamber of Commerce and Industry estimates that the shutdown had huge economic costs, estimated at over £1.9 billion.The economic cost of the continuing surveillance and shutdown in China’s Xinjiang province is likely to be higher. But India is a democracy and could be a role model, which is why the recent assertion of Communications and Information Technology Minister Ravishankar Prasad is worrying. He asserted in Parliament that the Indian citizen’s right to the internet was not a fundamental right. ‘While right of internet is important, security of the country is equally important…Can we deny (that) the internet is abused by terrorists…?’.The minister’s primary defence of the shutdown – that the internet was being abused by terrorists and others to foment unrest – has some merit. Our starting point therefore is that big tech platforms should be doing a significantly better job in monitoring content and in removing material designed to provoke violence and hatred. This is the original sin and Asian governments are right to worry about messaging platforms, for example, becoming preferred channels for venom and hate speech.To date, the big tech firms have made the right noises about monitoring and moderating content, but they have not gone far enough, providing governments with the excuse to routinely shut down access. To be blunt, self-regulation of the platforms is not working and tougher global regulation, enforcement and sanctions, possibly via the G20, would help.At the same time, better policing of the platforms will not resolve the issue entirely because governments regard internet shutdowns as a useful way to restrict human rights and to consolidate political control and surveillance over citizens. The international community – including nation-states, NGOs and the private sector – needs to come together and embrace two overarching principles:First, digital access is a fundamental human right and integrated into global declarations and norms.Second, to protect fragmentation and Balkanization of the internet, the digital pipes which carry data across national boundaries should be embedded into international law as being part of the global commons (just like oceans are under maritime law). This would raise the bar on countries which frequently restrict digital access to their citizens.Sensible though these recommendations might seem, it is obvious that many Asian governments would be loath to sign up to global declarations which would limit their policy options at home. There is an economic dimension to internet shutdowns, as the Kashmir case makes clear, which could be addressed by naming and shaming, just as the OECD’s Financial Action Task Force does for countries falling foul of money laundering regulations. Recommendations include:Digital access should be included in the UN’s Human Development Index.The World Bank’s closely followed Doing Business Index (DBI) should score countries favourably based on their commitment to offering unimpeded access to the internet. China and India watch the DBI rankings very closely and will be forced to pursue a more liberal approach if their rankings fall precipitously.Since internet shutdowns have a clear economic cost, particularly in payments and financial services, the International Monetary Fund (IMF) should make an annual determination of member countries (as part of its surveillance mandate) of the impact of shutdowns on economic activity and financial stability.Finally, all Asian governments have declared a public commitment to drive financial inclusion by providing digital access and identity to the poor and vulnerable. This mandate is at odds with frequent internet disruptions. A small vendor in Kashmir, Xinjiang or elsewhere in the region has limited or no recourse when the pipes are shut down. Central banks in the region need to step in by offering some level of protection, just like deposit insurance coverage.It is clear that many of these recommendations would be rejected outright by many Asian governments. They regard internet shutdowns as part of their policy toolkit to deal with external and internal threats to national security. In pursuing such a rigid approach, governments are wilfully curbing their citizens’ space for debate and ignoring a much broader issue of rights to digital access.Armed with a hammer, it is tempting for governments to regard the internet as a nail. The international community and citizens’ groups have an obligation to make such hammering very expensive. Full Article

In the early days of Prime Minister Shinzo Abe's second term in 2012, Japan sought to open a new era of bilateral relations with Russia. However, recent negotiations on the Kuril Islands/Northern Territories territorial dispute have stalled. Despite Abe’s extensive efforts to resolve the dispute, no concrete agreement has been reached so far. The speaker will provide an overview of the current state of Japan-Russia relations, including the prospect of resolving the territorial dispute during Prime Minister Abe's remaining days in office.

While early estimates suggest that a recession is inevitable, differing countries in Asia are generally deploying modest fiscal and monetary measures. This is true even in China, compared with the ‘whatever it takes’ approach pursued by Europe and America. How effective will these measures be in reviving growth and in easing the pain, particularly on the poor in developing countries in Asia? Is Asia witnessing a sudden but temporary halt in economic activity rather than a prolonged slowdown? At this virtual roundtable, the speakers will consider the likelihood of a recovery for trade in the region and will explore what lessons can be learned from countries like Singapore, who seem to be successfully managing the health and economic aspects of COVID-19.

The sanctions exposed Russia's key vulnerabilities - dependence on Western capital and advanced technology, with knock-on effects in other sectors.In an effort to offset the impact of sanctions, Russia has attempted a diversification strategy to non-Western states. The Asia-Pacific has emerged as a new export market for hydrocarbons and weapons, and as the main alternative to Western capital. Russia's self-proclaimed 'turn to the East' is intended to alleviate the sanctions burden and buy valuable time to come up with long-term solutions; but it has come at a high cost. In this discussion, Maria Shagina will examine the ways in which Asian states have helped mitigate the impact of Western sanctions and the pitfalls associated with it, while assessing the implications of Russia's pivot to Asia on its import substitution policy, and the effectiveness of sanctions overall.

si Beware Russian and Chinese Positioning for After the Pandemic By feedproxy.google.com Published On :: Thu, 09 Apr 2020 10:00:11 +0000 9 April 2020 Keir Giles Senior Consulting Fellow, Russia and Eurasia Programme @KeirGiles LinkedIn Google Scholar Authoritarian regimes can use the COVID-19 crisis to improve their international standing, taking advantage of others’ distraction. Their aims are different, but their methods have much in common. 2020-04-09-Russia-Aid-Serbia An airlifter of the Russian Aerospace Forces prepares to fly to Serbia carrying equipment and professionals during the COVID-19 crisis. Photo by Russian Defence MinistryTASS via Getty Images. Both Russia and China have mounted combined charm offensives and disinformation campaigns on the back of the pandemic. Shipments of ‘aid’ – reportedly of questionable utility and quality - have gone hand in hand with a concerted effort to deflect any blame from China for the early spread, and an ongoing drive by Russia to undermine states’ confidence and have sanctions lifted.These concurrent operations have very different objectives, as Russia seeks to subvert international order while China is continuing its bid to demonstrate global leadership - but in both cases, they are seeking long-term gains by exploiting the inattention and distraction of their targets.Both seek to present themselves as globally responsible stakeholders, but for divergent reasons – especially China which needs the rest of the world to recover and return to stability to ensure its own economic recovery. But despite this, the two campaigns appear superficially similar.Fertile ground for disinformationOne reason lies in the unique nature of the current crisis. Unlike political issues that are local or regional in nature, COVID-19 affects everybody worldwide. The perceived lack of reliable information about the virus provides fertile ground for information and disinformation campaigns, especially feeding on fear, uncertainty and doubt. But Russia in particular would not be succeeding in its objectives without mis-steps and inattention by Western governments.Confused reporting on Russia sending medical supplies to the United States showed Moscow taking advantage of a US administration in apparent disarray. Claims Russia was sending ’humanitarian aid’ were only belatedly countered by the US State Department pointing out it had been paid for. Meanwhile the earlier arrival of Russian military equipment in Italy also scored a propaganda victory for Russia, facilitated by curious passivity by the Italian government.In both cases Russia also achieved secondary objectives. With the United States, Russia scored bonus points by shipping equipment produced by a subsidiary of a company under US sanctions. In the case of Italy, Russian state media made good use of misleading or heavily edited video clips to give the impression of widespread Italian acclaim for Russian aid, combined with disdain for the efforts of the EU.Beijing’s external information campaigns have sought to deflect or defuse criticism of its early mishandling and misinformation on coronavirus and counter accusations of secrecy and falsifying data while also pursuing an opportunity to exercise soft power. For Moscow, current efforts boost a long-standing and intensive campaign to induce the lifting of sanctions, demonstrating if nothing else that sanctions are indeed an effective measure. Official and unofficial lobbying has intensified in numerous capital cities, and will inevitably find supporters.But both the aid and the information campaigns are seriously flawed. While appropriate and useful aid for countries that are struggling should of course be welcomed, both Russian and Chinese equipment delivered to Europe has repeatedly been found to be inappropriate or defective. Russian photographs of cardboard boxes stacked loose and unsecured in a transport aircraft bound for the United States sparked alarm and disbelief among military and aviation experts - and there has still been no US statement on what exactly was purchased, and whether it was found to be fit for purpose when it arrived.Reporting from Italy that the Russian equipment delivered there was ‘80% useless’ has not been contradicted by the Italian authorities. In fact, although the Italian sources criticizing Russia remain anonymous it is striking that - President Trump aside - no government has publicly endorsed materials and assistance received from Russia as actually being useful and helpful.Even in Serbia, with its traditionally close ties with Russia, the only information forthcoming on the activities of the Russian Nuclear, Biological and Chemical Protection Troops and their equipment that arrived on April 3 was from Russian press releases.Both countries’ strategic communications efforts are similarly fallible. China’s notoriously heavy-handed approach to its critics is of only limited use in the face of such a severe and immediate threat. One suggestion that the virus originated in the US – an early response to US criticism – has already been walked back by the Chinese diplomat who made it.And Russia continues to be capable of spectacularly misjudging its targets. When investigative journalists looked more closely at the nature of the assistance to Italy, Russia’s official response was rage and personal threats, laying bare the real nature of the campaign and immediately alienating many of those whom Moscow had sought to win over.Errors and deficiencies such as these provide opportunities to mitigate the worst side-effects of the campaigns. And actions by individuals can also mitigate much of the impact. The most effective disinformation plays on deeply emotional issues and triggers visceral rather than rational reactions.Advocates of ’informational distancing’ as well as social distancing suggest a tactical pause to assess information calmly, instead of reacting or spreading it further unthinkingly. This approach would bolster not only calm dispassionate assessment of the real impact of Russian and Chinese actions, but also counter spreading of misinformation on the pandemic as a whole - especially when key sources of disinformation are national leaders seeking to politicize or profit from the crisis.Limitations of Russian and Chinese altruism must be stated clearly and frankly to fill gaps in public understanding. Where help is genuine, it should of course be welcomed: but if it is the case that assistance received from Moscow or Beijing is not appropriate, not useful, or not fit for purpose, this should be acknowledged publicly.Even without central direction or coordination with other Russian strategic communications efforts, the self-perpetuating Russian disinformation ecosystem continues to push narratives designed to undermine confidence in institutions and their ability to deal with the crisis. This too must continue to be monitored closely and countered where it matters.In all cases, miscalculations by Russia or China that expose the true intent of their campaigns – no matter how different their objectives might be - should be watched for closely and highlighted where they occur.Despite the enormity of the present emergency it is not a time for any government to relax its vigilance over longer-term threats. States must not lose sight of manoeuvres seeking to exploit weakness and distraction. If Russia and China emerge from the current crisis with enhanced authority and unjustifiably restored reputations, this will make it still harder to resist their respective challenges to the current rules-based international order in the future.

si Putting Music on the Map By www.ams.org Published On :: Wed, 26 Dec 2007 11:39:57 -0500 Mathematics and music have long been closely associated. Now a recent mathematical breakthrough uses topology (a generalization of geometry) to represent musical chords as points in a space called an orbifold, which twists and folds back on itself much like a Mobius strip does. This representation makes sense musically in that sounds that are far apart in one sense yet similar in another, such as two notes that are an octave apart, are identified in the space.This latest insight provides a way to analyze any type of music. In the case of Western music, pleasing chords lie near the center of the orbifolds and pleasing melodies are paths that link nearby chords. Yet despite the new connection between music and coordinate geometry, music is still more than a connect-the-dots exercise, just as mathematics is more than addition and multiplication.

si Pulling Out (from) All the Stops - Visiting all of NY's subway stops in record time By www.ams.org Published On :: Mon, 18 May 2009 09:31:17 -0400 With 468 stops served by 26 lines, the New York subway system can make visitors feel lucky when they successfully negotiate one planned trip in a day. Yet these two New Yorkers, Chris Solarz and Matt Ferrisi, took on the task of breaking a world record by visiting every stop in the system in less than 24 hours. They used mathematics, especially graph theory, to narrow down the possible routes to a manageable number and subdivided the problem to find the best routes in smaller groups of stations. Then they paired their mathematical work with practice runs and crucial observations (the next-to-last car stops closest to the stairs) to shatter the world record by more than two hours! Although Chris and Matt.s success may not have huge ramifications in other fields, their work does have a lot in common with how people do modern mathematics research * They worked together, frequently using computers and often asking experts for advice; * They devoted considerable time and effort to meet their goal; and * They continually refined their algorithm until arriving at a solution that was nearly optimal. Finally, they also experienced the same feeling that researchers do that despite all the hours and intense preparation, the project .felt more like fun than work.

si Matching Vital Needs - Increasing the number of live-donor kidney transplants By www.ams.org Published On :: Wed, 1 Jul 2009 10:07:19 -0400 A person needing a kidney transplant may have a friend or relative who volunteers to be a living donor, but whose kidney is incompatible, forcing the person to wait for a transplant from a deceased donor. In the U.S. alone, thousands of people die each year without ever finding a suitable kidney. A new technique applies graph theory to groups of incompatible patient-donor pairs to create the largest possible number of paired-donation exchanges. These exchanges, in which a donor paired with Patient A gives a kidney to Patient B while a donor paired with Patient B gives to Patient A, will dramatically increase transplants from living donors. Since transplantation is less expensive than dialysis, this mathematical algorithm, in addition to saving lives, will also save hundreds of millions of dollars annually. Naturally there can be more transplants if matches along longer patient-donor cycles are considered (e.g., A.s donor to B, B.s donor to C, and C.s donor to A). The problem is that the possible number of longer cycles grows so fast hundreds of millions of A >B>C>A matches in just 5000 donor-patient pairs that to search through all the possibilities is impossible. An ingenious use of random walks and integer programming now makes searching through all three-way matches feasible, even in a database large enough to include all incompatible patient-donor pairs.

si Resisting the Spread of Disease - Part 2 By www.ams.org Published On :: Mon, 28 Sep 2009 09:58:07 -0400 One of the most useful tools in analyzing the spread of disease is a system of evolutionary equations that reflects the dynamics among three distinct categories of a population: those susceptible (S) to a disease, those infected (I) with it, and those recovered (R) from it. This SIR model is applicable to a range of diseases, from smallpox to the flu. To predict the impact of a particular disease it is crucial to determine certain parameters associated with it, such as the average number of people that a typical infected person will infect. Researchers estimate these parameters by applying statistical methods to gathered data, which aren.t complete because, for example, some cases aren.t reported. Armed with reliable models, mathematicians help public health officials battle the complex, rapidly changing world of modern disease. Today.s models are more sophisticated than those of even a few years ago. They incorporate information such as contact periods that vary with age (young people have contact with one another for a longer period of time than do adults from different households), instead of assuming equal contact periods for everyone. The capacity to treat variability makes it possible to predict the effectiveness of targeted vaccination strategies to combat the flu, for instance. Some models now use graph theory and matrices to represent networks of social interactions, which are important in understanding how far and how fast a given disease will spread.

si Assigning Seats - Part 2 By www.ams.org Published On :: Fri, 10 Dec 2010 15:00:57 -0500 As difficult as it is to do the census, the ensuing process of determining the number of congressional seats for each state can be even harder. The basic premise, that the proportion of each state's delegation in the House should match its proportion of the U.S. population, is simple enough. The difficulty arises when deciding what to do with the fractions that inevitably arise (e.g., New York can't have 28.7 seats). Over the past 200 years, several methods of apportioning seats have been used. Many sound good but can lead to paradoxes, such as an increase in the total number of House seats actually resulting in a reduction of a state's delegation. The method used since the 1940s, whose leading proponent was a mathematician, is one that avoids such paradoxes. A natural question is Why 435 seats? Nothing in the Constitution mandates this number, although there is a prohibition against having more than one seat per 30,000 people. One model, based on the need for legislators to communicate with their constituents and with each other, uses algebra and calculus to show that the ideal assembly size is the cube root of the population it represents. Remarkably, the size of the House mirrored this rule until the early 1900s. To obey the rule now would require an increase to 670, which would presumably both better represent the population and increase the chances that the audience in the seats for those late speeches would outnumber the speaker.

si Harnessing Wind Power - Part 1 By www.ams.org Published On :: Wed, 5 Oct 2011 14:01:45 -0400 Mathematics contributes in many ways to the process of converting wind power into usable energy. Large-scale weather models are used to find suitable locations for wind farms, while more narrowly focused models incorporating interactions arising from factors such as wake effects and turbulence specify how to situate individual turbines within a farm. In addition, computational fluid dynamics describes air flow and drag around turbines. This helps determine the optimal shapes for the blades, both structurally and aerodynamically, to extract as much energy as possible, and keep noise levels and costs down. Mathematics also helps answer two fundamental questions about wind turbines. First, why three blades? Turbines with fewer blades extract less energy and are noisier (because the blades must turn faster). Those with more than three blades would capture more energy but only about three percent more, which doesn.t justify the increased cost. Second, what percentage of wind energy can a turbine extract? Calculus and laws of conservation provide the justification for Betz Law, which states that no wind turbine can capture more than 60% of the energy in the wind. Modern turbines generally gather 40-50%. So the answer to someone who touts a turbine that can capture 65% of wind energy is "All Betz" are off.

si Getting a Handle on Obesity By www.ams.org Published On :: Fri, 15 Jun 2012 15:50:31 -0400 Once a problem only in the developed world, obesity is now a worldwide epidemic. The overwhelming cause of the epidemic is a dramatic increase in the food supply and in food consumption not a surprise. Yet there are still many mysteries about weight change that can.t be answered either inside the lab, because of the impracticality of keeping people isolated for long periods of time, or outside, because of the unreliability of dietary diaries. Mathematical models based on differential equations can help overcome this roadblock and allow detailed analysis of the relationship between food intake, metabolism, and weight change. The models. predictions fit existing data and explain such things as why it is hard to keep weight off and why obese people are more susceptible to further weight gain. Researchers are also investigating why dieters often plateau after a few months and slowly regain weight. A possible explanation is that metabolism slows to match the drop in food consumed, but models representing food intake and energy expenditure as a dynamical system show that such a weight plateau doesn.t take effect until much later. The likely culprit is a combination of slower metabolism and a lack of adherence to the diet. Most people are in approximate steady state, so that long-term changes are necessary to gain or lose weight. The good news is that each (enduring) drop of 10 calories a day translates into one pound of weight loss over three years, with about half the loss occurring in the first year.

si Catching and Releasing: Part 2 By www.ams.org Published On :: Mon, 1 Oct 2012 09:46:50 -0400 There.s more mathematics involved in juggling than just trying to make sure that the number of balls (or chainsaws) that hits the ground stays at zero. Subjects such as combinatorics and abstract algebra help jugglers answer important questions, such as whether a particular juggling pattern can actually be juggled. For example, can balls be juggled so that the time period that each ball stays aloft alternates between five counts and one? The answer is Yes. Math also tells you that the number of balls needed for such a juggling pattern is the average of the counts, in this case three. Once a pattern is shown to be juggleable and the number of balls needed is known, equations of motion determine the speed with which each ball must be thrown and the maximum height it will attain. Obviously the harder a juggler throws, the faster and higher an object will go. Unfortunately hang time increases proportionally to the square root of the height, so the difficulty of keeping many objects in the air increases very quickly. Both math and juggling have been around for millennia yet questions still remain in both subjects.
