Unending Cycles of Abuse: The Practice of Bacha Bazi in Afghanistan

Research Event

6 February 2020 - 6:00pm to 7:00pm

Chair: Champa Patel, Head of Asia-Pacific Programme, Chatham House

Afghanistan has suffered decades of armed conflict resulting in a heavily armed and militarized society involving multiple armed actors and with children being disproportionately affected by the conflict. In March 2019, the Afghanistan government criminalized the harmful practice of bacha bazi, or ‘boy play’, which triggers a range of human rights violations against boys and young men. However, recent research conducted by the All Survivors Project and Youth Health and Development Organisation demonstrates that the practice is widely prevalent due to poverty, prevailing gender norms and widespread impunity. This event will look at research that was conducted in the four provinces of Balkh, Herat, Kandahar and Kabul following interviews with over 100 key informants, 24 survivors and with 13 focus group discussions. 

The event will be preceded by the screening of a documentary on the practice of bacha bazi in Afghanistan which includes interviews with survivors, key government officials and NGOs. The speakers will discuss how an increase in the intensity of conflict in recent years has removed protection mechanisms and increased the vulnerability of all children to conflict-related sexual violence.

The recalibration of Chinese assertiveness: China's responses to the Indo-Pacific challenge

8 January 2020 , Volume 96, Number 1

Feng Liu

In response to the changing geopolitical landscape in Asia, both China and the United States attempt to alter the regional order in their own favour, both in the economic and security realms. This article shows how diverging views on future arrangements are leading to strategic shifts and increasing tension between these two Great Powers. As part of its quest for Great-Power status, China has been actively pushing its regional initiatives such as the Belt and Road Initiative (BRI) and the Asian Infrastructure Investment Bank (AIIB), as well as adopting assertive security policies towards its neighbours. In contrast, in order to counter China's growing influence America's regional strategy is undergoing a subtle shift from ‘rebalancing to Asia’ to focusing on the ‘Indo-Pacific’ region. However, amid an intensifying trade war and other challenges facing the region, China has chosen to moderate its proactive foreign policy-orientation in the past few years. In particular, China has made attempts to downplay its domestic rhetoric, rebuild strategic relationship with India and Japan, and to reassure ASEAN states in the South China Sea. In response to the Indo-Pacific strategy, it would be more effective for China to articulate a more inclusive regional vision and promote an institutional framework that also accommodates a US presence in the region.

Japan's ‘Indo-Pacific’ question: countering China or shaping a new regional order?

8 January 2020 , Volume 96, Number 1

Kei Koga

Japan's primary objective of the ‘free and open Indo-Pacific’ (FOIP) strategy is to shape and consolidate regional order in the Indo-Pacific region based on the existing rules-based international order. The concept initially aimed to achieve two different objectives—shaping a regional order in the Indo-Pacific and ensuring the defence of Japan; however, Japan has gradually shifted its strategic focus onto the former, separating national defence from the FOIP concept, which reflects a change in the degree of its commitment to the two objectives. On the one hand, as its overall security strategy, Japan has determined to steadily enhance its national defence by increasing its own defence capabilities and strengthening the US–Japan alliance, while transforming its partnerships with like-minded states, such as Australia and India, into a diplomatic, and potentially military, alignment. This has been brought about by shifts in the regional balance of power, particularly the rise of China and the relative decline of the United States. On the other hand, as part of its FOIP strategy, Japan's attempts to build a new regional order in the Indo-Pacific region aim to defend the existing rules-based order established by the United States from challengers, particularly China. Yet, given the strategic uncertainty over Japan's international coalition-building efforts to create a new regional order, Japan has made its approach flexible; Tokyo is using its ambiguous FOIP concept to gauge other states' responses, understand their perspectives, and change its strategic emphases accordingly—so-called ‘tactical hedging’. Japan has pursued similar means to achieve the two key objectives. Nevertheless, the country's core interest, the defence of Japan, is more imperative than building a regional order in the Indo-Pacific region, and Japan faces different types of challenges in the future.

Evasive balancing: India's unviable Indo-Pacific strategy

8 January 2020 , Volume 96, Number 1

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.

Understanding the dynamics of the Indo-Pacific: US–China strategic competition, regional actors, and beyond

6 November 2019 , Volume 96, Number 1

The first issue of International Affairs in 2020 explores the geopolitics of the 'Indo-Pacific' region.

Kai He and Mingjiang Li

As a geographical concept, ‘Indo-Pacific’ has existed for decades. As a political and strategic concept, it has since 2010 gradually become established in the foreign policy lexicon of some countries, especially Australia, India, Japan and the United States. However, China seems to be reluctant to identify itself as part of the Indo-Pacific; Chinese leaders believe that the US-led Indo-Pacific strategy aims to contain China's rise. While the battle between the two geographical concepts ‘Indo-Pacific’ and ‘Asia–Pacific’ may be fairly easily settled in the future, US–China strategic competition has just begun. Will the Indo-Pacific become a battlefield for US–China rivalry? How will China cope with the US ‘free and open Indo-Pacific’ (FOIP) strategy? How will other regional actors respond to the US–China strategic competition in the Indo-Pacific? What are the strategic implications of the ‘Indo-Pacific’ concept for regional order transformation? How will the Indo-Pacific be institutionalized, economically, politically and strategically? This article introduces the January 2020 special issue of International Affairs, which aims to address those questions, using both country-specific and regional perspectives. Seven articles focus on the policy responses of major players (Australia, China, India, Indonesia, Japan and ASEAN) to the US FOIP strategy and related US–China rivalry in the region. A further three articles examine the profound implications of Indo-Pacific dynamics for regional institution-building and for geopolitical and geo-economic architecture.

Is Myanmar Running Out of Time?

Research Event

17 February 2020 - 1:00pm to 2:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Thant Myint-U, Conservationist; Author, The Hidden History of Burma: Race, Capitalism, and the Crisis of Democracy in the 21st Century
Chair: Champa Patel, Head of Asia-Pacific Programme, Chatham House

Just a few years ago the West was celebrating what appeared to be the conclusion of a quarter-century long contest between Myanmar’s democrats and a military dictatorship. Today, the country stands charged with genocide at the International Court of Justice, with Aung San Suu Kyi leading the defence. Is Myanmar a democratic transition gone awry? Or something else entirely?  

The speaker will argue that Myanmar is not the simple morality tale often portrayed. It has instead become the stage for some of the world’s most pressing challenges such as climate change, explosive inequality and rising populism, the impact of social media; and the rise of China as the next global superpower.

In this context, are 20th century democratic institutions and free-market reforms the correct remedy for a country plagued by the legacies of colonialism, decades of civil war, tyranny and a predatory economic system? The speaker will offer a prognosis for Myanmar’s future, assessing the question of whether it will become Asia’s next failed state.

This event will be held off the record.

Network Power in the Asia-Pacific: Making Sense of the New Regionalism and Opportunities for Cooperation

Research Event

7 February 2020 - 9:45am to 5:30pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

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.

Will a Devastating Bushfire Season Change Australia’s Climate Stance?

23 January 2020

Madeleine Forster

Richard and Susan Hayden Academy Fellow, International Law Programme

Professor Tim Benton

Research Director, Emerging Risks; Director, Energy, Environment and Resources Programme
With Australians experiencing first-hand the risks of climate change, Madeleine Forster and Tim Benton examine the influencers, at home or abroad, that could push the government towards more action.

2020-01-23-FireNSW.jpg

Residents look on as flames burn through bush on 4 January 2020 in Lake Tabourie, NSW. Photo: Getty Images.

The 2019–20 fire season in Australia has been unprecedented. To date, an estimated 18 million hectares of fire has cut swathes through the bush – an area greater than that of the average European country and over five times the size of blazes in the Amazon.

This reflects previous predictions of Australian science. Since 2008 and as recently as 2018, scientific bodies have warned that climate change will exacerbate existing conditions for fires and other climatic disasters in Australia. What used to be once-in-a-generation fires now re-appear within 10–15 years with increased ferocity, over longer seasons.

In a country known for climate denial and division, debate has erupted around bushfire management and climate change. One of these is whether controlled burns are the answer to Australia’s climate-affected fire conditions.

There is no single risk reduction strategy. Controlled burning remains key, if adapted to the environment and climate

But when three out of four seasons in a year can support destructive bushfires, there are clear limits to what controlled burning and other fire management techniques can achieve. Other ‘adaptation’ measures are also likely to provoke intense debate – including bush clearance. As one Australian expert offered to highlight where Australia has got to, families should probably not go on holiday to bush and beach during the height of summer when temperatures and fire risk peaks. 

So, unless Australia is prepared to debate radical changes to where people live and how land is used, the limits to adaptation imply the need for mitigation. This means supporting ambitious global greenhouse emissions reductions targets. As research from Victoria, one fire-prone state in Australia, highlights, ‘the emissions pathway we follow is the largest determinant of change to many variables [such as temperature] beyond the next few decades.’

Can Australia become a more active global partner on emissions?

Australia accounts for just over one per cent of global emissions, so reducing domestic emissions – even though on a per capita basis they are the highest in the world – will not reduce Australia’s climate risk. Showing international leadership and supporting a powerful coalition of the willing to tackle climate change is the only way ahead. By showing a willingness to adopt climate ambition, Australia can help more constructive worldwide action, and thereby reduce its own risk exposure. 

Leading by example is a politically difficult issue for Australia. Prime Minister Scott Morrison was re-elected in May 2019 on an economic stability platform, and a promise not to imperil employment growth through climate action. Australia has contested UN estimates that it will not meet its existing modest goals for domestic emissions, by seeking to rely on carryover credits from action under the Kyoto Protocol as proof of progress.

It has also distanced itself from concerns over global supply and demand in fossil fuels. Australia remains a global supplier for fossil fuels, including coal – the nation’s coal exports accounted for $67 billion in revenues in 2019 in an expanding but changing Asian market, supplying ‘some of the cheapest electricity in the world’.

Possible influencers of change

With Australians experiencing first-hand the risks of climate change, there is already pressure to do more. Many are sceptical this will translate into domestic targets or export policies that give Australia the moral authority to ask for more action on the global stage.

Here, diverse groups who share a common interest in seeing Australia recover from the bushfires and address future climate risks could be key.

Importantly this includes rural and urban-fringe communities affected by the bushfires. They were part of Morrison’s traditional supporter-base but are angry at the government’s handling of the crisis and increasingly see how tiptoeing around emissions (including exports) has also ‘buried’ open discussion at home on climate-readiness.

Australian states could also find themselves taking a lead role. Virtually all jurisdictions have now committed to their own goals, most based on zero-carbon goals by 2050 (as has New Zealand). These can support modelling for Australia’s energy transition from coal, through gas, to market competitive renewables, while also help to ensure this reflects community expectations on jobs, electricity prices and other costs. 

Other emerging voices include the insurance and banking sectors (the Reserve Bank of Australia warned of the long-term financial stability risks of climate change before the fires) and indigenous Australians (one group of Torres Strait Islanders have filed a complaint to the UN Human Rights Committee which, if heard, will place Australia’s emissions record under the spotlight again). Their challenge now is finding a common language on what a cohesive approach to addressing climate change risk looks like. 

The international picture is mixed. The United States’ poor federal climate policy is a buffer for Australia. French President Emmanuel Macron has tried to raise the cost of inaction for Australia in current EU–Australia trade negotiations, but many large emitters in the Indo-Pacific region remain key Australian trading partners, investors and buyers of Australian coal. 

In the meantime, the United Kingdom is preparing for the meeting of parties to the Paris Agreement in Glasgow in November. A key global event following Brexit, the UK will no doubt be hoping to encourage a leadership circle with national commitments that meet global need to make the Glasgow meeting a success.

The UK public has expressed enormous sympathy for Australia in the bushfires and outrage over ‘climate denialism.’ Australia’s experience will be a cautionary tale of the effects of climate change at the meeting. Could the UK also support Australia to become a less reluctant partner in global climate action?

Centralization is Hobbling China’s Response to the Coronavirus

6 February 2020

Dr Yu Jie

Senior Research Fellow on China, Asia-Pacific Programme
The sluggish early reaction by officials should not have come as a surprise.

2020-02-06-CVT.jpg

The coronavirus outbreak in China poses a tremendous test for Beijing. Beyond the immediate public health crisis, the Chinese Communist Party faces a stuttering economy, growing public anger and distrust, and a potentially heavy blow to its global reputation.

The hesitant early response to the outbreak sheds light on the way the Chinese bureaucracy approaches crises at a time when the party leadership is tightening control at almost all levels of society. At first, officials in Wuhan attempted to censor online discussions of the virus. This changed only after President Xi Jinping’s call for a much more robust approach was followed by a sudden increase in the state media coverage of the outbreak. There is no doubt that Xi’s intervention will greatly speed up the response to the crisis, which should be welcomed.

Despite China’s experience with the SARS epidemic between 2002 and 2004, the sluggish reaction by officials in Wuhan should not have come as a surprise. The tendency among bureaucrats to play down crises is deeply entrenched. And, ironically, the party leadership’s recent push for greater bureaucratic accountability and its promise of stiffer punishment for those who take a 'do little' approach have also contributed to the habit of covering up disasters.

Xi has launched an ambitious programme to reform the governance of the Communist Party and re-centralize political control. This has reinforced the tendency of officials to avoid making important decisions and instead to wait for instructions from the party leadership.

For decades, local governments have made things happen in China. But with tighter regulation of lower-level bureaucrats, civil servants across the system now seem less ready, and able, to provide their input, making ineffective and even mistaken policy more likely.

Explainer: Coronavirus - What You Need to Know

World-renowned global health expert Professor David Heymann CBE explains the key facts and work being done on the coronavirus outbreak.

Moreover, the coronavirus outbreak could not have happened at a worse time. Last year was tumultuous and saw China fighting an economic slowdown while also dealing with an increasingly hostile international environment. Now, as the authorities take steps to contain the disease, economic activity has come to a near standstill, with public transport curbed and restaurants and entertainment venues shuttered.

This contrasts with SARS, when double-digit growth in gross domestic product enabled Beijing to raise government expenditure to tackle the outbreak. Today, the Chinese economy is running into some of the most difficult challenges it has faced since the global financial crisis.

In response to the slowdown in growth, Beijing has adopted loose fiscal policy, with an emphasis on public investment. It also continues to push big banks to cut interest rates for individual borrowers and small businesses which were already suffering from the effects of the trade war with the US before the coronavirus struck.

The outbreak should give new impetus to governments, not least those that have close economic ties with China. Being a great power with ambitions for global leadership, as well as domestic reform, is not easy. Even without multi-party elections, it involves increasing, and often uncomfortable, scrutiny. As President Xi himself has put it: the road is long and the task is weighty.

Bangladesh: The Trade-Off Between Economic Prosperity and Human Rights

Bangladesh's recent gains in economic and social indices, set against its record of corruption and poor civil rights, has at times been termed the ‘Bangladesh Paradox’. Yet this label is overly simplistic; the current situation proves that these trends can coexist.

The Awami League government, in power since 2009, has increased political stability, delivered unprecedented economic and social advances, and adopted a counter-terrorism strategy to stamp out extremist groups. At the same time, it is criticized for curbing civil rights and failing to hold credible elections. However, as the two previous regimes have demonstrated, the rights situation is unlikely to improve even if the Awami League were replaced.

How did worsening rights become a feature of the state irrespective of its political dispensation? An unresolved contest between political and non-political state actors may hold the key to that puzzle. The perils of the current dispensation have recently manifested in weakening economic indicators, which jeopardize the very stability and social progress for which the country has garnered much praise.

Only a few months into 2020, the coronavirus pandemic has presented a huge challenge for China’s ruling party against an already tumultuous 12 months of economic slowdown coupled with an increasingly hostile international environment. The crisis looks set to worsen a deteriorating relationship between the US and China as the two countries battle to avoid further economic ramifications. It has also undermined President Xi Jinping and the Chinese Communist Party’s domestic political legitimacy and economic growth.

The panellists will examine the wider geopolitical fallout of the coronavirus pandemic and discuss China’s future economic planning. How will the COVID-19 outbreak further strain the US-China relationship? What effect will this have on global trade and vulnerable supply chains at a time when cooperation is needed more than ever? And to what extent is the ruling party addressing growing concerns over job losses, wealth inequality and a lack of social mobility?

Justice for the Rohingya: Lessons from the Khmer Rouge Tribunal

8 April 2020

Sandra Smits

Programme Manager, Asia-Pacific Programme
The Cambodian case study illustrates the challenges of ensuring justice and accountability for the Rohingya in Myanmar.

2020-04-08-Rohingya.jpg

International criminal justice provides a stark reminder that state sovereignty is not an absolute, and that the world’s most heinous crimes should be prosecuted at an international level, particularly where domestic systems lack the capacity or will to hold perpetrators to account. 

The post-Cold War period witnessed a dramatic rise in the number of international tribunals with jurisdiction over war crimes and serious human rights abuses in countries including Cambodia, East Timor, Rwanda, Liberia, Sierra Leone and Yugoslavia. With these processes approaching, or having reached the end of their dockets, many have called for the creation of new tribunals to address more recent conflicts, including the army crackdown in Myanmar in 2017 that resulted in evidence of crimes against humanity against the Rohingya

In January this year, the International Court of Justice (ICJ) imposed emergency provisional measures on Myanmar, instructing it to prevent genocidal violence against its Rohingya minority. But a final judgement is expected to take years and the ICJ has no way of enforcing these interim measures. Myanmar has already responded defiantly to international criticism

Model for justice

Myanmar is not the first country to face scrutiny for such crimes in Southeast Asia. The Extraordinary Chambers in the Courts of Cambodia (ECCC), more commonly known as the Khmer Rouge Tribunal was established in 1997 to prosecute Khmer Rouge leaders for alleged violations of international law and serious crimes perpetrated during the Cambodian genocide. This provides an opportunity to consider whether the Tribunal can act as a ‘hybrid’ model for justice in the region. 

The first lesson that can be taken from the Cambodian context is that the state must have the political will and commitment to pursue accountability. It was indeed the Cambodian government itself, who requested international assistance from the United Nations (UN), to organize a process for holding trials. The initial recommendation of the UN-commissioned Group of Experts was for the trial to be held under UN control, in light of misgivings about Cambodia’s judicial system. Prime Minister Hun Sen rejected this assessment and in prolonged negotiations, continued to spearhead the need for domestic involvement (arguably, in order to circumscribe the search for justice). This eventually resulted in the creation of a hybrid body consisting of parallel international and Cambodian judges and prosecutors with supermajority decision-making rules.   

It is worth noting that the Hun Sen government initially chose to do business with former Khmer Rouge leaders, until it became more advantageous to embrace a policy of putting them on trial. It is possible to infer from this that there will be no impetus for action in Myanmar until it is domestically advantageous to do so. At present, this appetite is clearly lacking, demonstrated by de-facto leader Aung San Suu Kyi shying away from accountability and instead defending the government’s actions before the ICJ.

One unique aspect of the Khmer Rouge Tribunal has been the vast participation by the Cambodian people in witnessing the trials as well as widespread support for the tribunal. This speaks to the pent-up demand in Cambodia for accountability and the importance of local participation. While international moral pressure is clear, external actors cannot simply impose justice for the Rohingya when there is no domestic incentive or support to pursue this. The reality is that the anti-Rohingya campaign has galvanized popular support from the country’s Buddhist majority. What is more, the Rohingya are not even seen as part of Myanmar so there is an additional level of disenfranchisement.

Secondly, the Cambodian Tribunal illustrates the need for safeguards against local political interference. The ECCC was designed as national court with international participation. There was an agreement to act in accordance with international standards of independence and impartiality, but no safeguards in place against serious deficiencies in the Cambodian judicial system. Close alliances between judges and the ruling Cambodian People’s Party, as well as high levels of corruption meant the tribunal effectively gave Hun Sen’s government veto power over the court at key junctures. Despite the guise of a hybrid structure, the Cambodian government ultimately retained the ability to block further prosecutions and prevent witnesses from being called. 

In Myanmar, political interference could be a concern, but given there is no popular support for justice and accountability for crimes committed against the Rohingya, the prospects of a domestic or hybrid process remain unlikely. However, there are still international options. The investigation by the International Criminal Court (ICC) into crimes that may have taken place on the Myanmar–Bangladesh border represents a potential route for justice and accountability. The UN Human Rights Council has also recently established the Independent Investigative Mechanism for Myanmar (IIMM), mandated to collect and preserve evidence, as well as to prepare files for future cases before criminal courts.

Finally, the Cambodian case illustrates the culture of impunity in the region. The ECCC was conceived partly as a showcase for international standards of justice, which would have a ‘contagion effect’ upon the wider Cambodian and regional justice systems. 

Cambodia was notorious for incidents in which well-connected and powerful people flouted the law. This culture of impunity was rooted in the failure of the government to arrest, try and punish the Khmer Rouge leadership. The Tribunal, in holding perpetrators of the worst crimes to account, sought to send a clear signal that lesser violations would not be tolerated in the same way. Arguably, it did not achieve this in practice as Cambodia still has a highly politicized judicial system with high levels of corruption and clear limits to judicial independence

What this illustrates is that the first step towards accountability is strengthening domestic institutions. The United Nation’s Special Rapporteur on the situation of human rights in Myanmar has urged domestic authorities to embrace democracy and human rights, highlighting the need to reform the judicial system in order to ensure judicial independence, remove systemic barriers to accountability and build judicial and investigatory capacity in accordance with international standards. Based on this assessment, it is clear that domestic institutions are currently insufficiently independent to pursue accountability.

The ECCC, despite its shortcomings, does stand as proof that crimes against humanity will not go completely unpunished. However, a process does not necessarily equal justice. The region is littered with justice processes that never went anywhere: Indonesia, Nepal, and Sri Lanka. International recourse is also challenging in a region with low ratification of the ICC, and the absence of regional mechanisms like the Inter-American Court of Human Rights, the European Court of Human Rights, and the African Court on Human and Peoples’ Rights (although their remit is not mass atrocity prosecutions). 

The Cambodian case study illustrates the challenges of ensuring justice and accountability within the region. The end of impunity is critical to ensure peaceful societies, but a purely legalistic approach will fail unless it is supported by wider measures and safeguards. It is these challenges, that undermine the prospects for ensuring justice for the Rohingya within Myanmar.

Webinar: Hong Kong: Dissent in the Age of Coronavirus

Research Event

17 April 2020 - 12:00pm to 1:00pm

Event participants

Antony Dapiran, Writer; Lawyer; Author of City on Fire: The Fight for Hong Kong
Chair: Jessie Lau, Journalist; Researcher; Artist; Board Member and Online Editor-in-Chief, NüVoices

Street protests demanding greater autonomy and democratization in Hong Kong upended the city for seven months last year. However, with the outbreak of the coronavirus in China in late January, the protests quickly died out. What does this mean for the city's protest movement?

The speaker will argue that, despite the lack of high-profile street rallies, protest in the city is continuing. It is building on and evolving from last year's protest movement albeit in different forms. At the same time, the Hong Kong authorities, emboldened by a hard line from Beijing, have begun cracking down on activists and protesters in the city as they seek to put a lid on dissent ahead of important Legislative Council elections scheduled for this September.

In this webinar, the speaker will look at the current state of dissent in Hong Kong and prospects for Hong Kong's future.

This event will be held on the record.

Beware Russian and Chinese Positioning for After the Pandemic

9 April 2020

Keir Giles

Senior Consulting Fellow, Russia and Eurasia Programme
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.

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 disinformation

One 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.

Blaming China Is a Dangerous Distraction

15 April 2020

Jim O'Neill

Chair, Chatham House
Chinese officials' initial effort to cover up the coronavirus outbreak was appallingly misguided. But anyone still focusing on China's failings instead of working toward a solution is essentially making the same mistake.

As the COVID-19 crisis roars on, so have debates about China’s role in it. Based on what is known, it is clear that some Chinese officials made a major error in late December and early January, when they tried to prevent disclosures of the coronavirus outbreak in Wuhan, even silencing healthcare workers who tried to sound the alarm.

China’s leaders will have to live with these mistakes, even if they succeed in resolving the crisis and adopting adequate measures to prevent a future outbreak. What is less clear is why other countries think it is in their interest to keep referring to China’s initial errors, rather than working toward solutions.

For many governments, naming and shaming China appears to be a ploy to divert attention from their own lack of preparedness. Equally concerning is the growing criticism of the World Health Organization (WHO), not least by Donald Trump who has attacked the organization - and threatens to withdraw US funding - for supposedly failing to hold the Chinese government to account.

Unhelpful and dangerous

At a time when the top global priority should be to organize a comprehensive coordinated response to the dual health and economic crises unleashed by the coronavirus, this blame game is not just unhelpful but dangerous.

Globally and at the country level, we all desperately need to do everything possible to accelerate the development of a safe and effective vaccine, while in the meantime stepping up collective efforts to deploy the diagnostic and therapeutic tools necessary to keep the health crisis under control.

Given there is no other global health organization with the capacity to confront the pandemic, the WHO will remain at the center of the response, whether certain political leaders like it or not.

Having dealt with the WHO to a modest degree during my time as chairman of the UK’s independent Review on Antimicrobial Resistance (AMR), I can say that it is similar to most large, bureaucratic international organizations.

Like the International Monetary Fund (IMF), the World Bank, and the United Nations, it is not especially dynamic or inclined to think outside the box. But rather than sniping at these organizations from the sidelines, we should be working to improve them.

In the current crisis, we all should be doing everything we can to help both the WHO and the IMF to play an effective, leading role in the global response. As I have argued before, the IMF should expand the scope of its annual Article IV assessments to include national public-health systems, given that these are critical determinants in a country’s ability to prevent or at least manage a crisis like the one we are now experiencing.

I have even raised this idea with IMF officials themselves, only to be told that such reporting falls outside their remit because they lack the relevant expertise. That answer was not good enough then, and it definitely isn’t good enough now.

If the IMF lacks the expertise to assess public health systems, it should acquire it. As the COVID-19 crisis makes abundantly clear, there is no useful distinction to be made between health and finance. The two policy domains are deeply interconnected, and should be treated as such.

In thinking about an international response to today’s health and economic emergency, the obvious analogy is the 2008 global financial crisis which started with an unsustainable US housing bubble, fed by foreign savings owing to the lack of domestic savings in the United States.

When the bubble finally burst, many other countries sustained more harm than the US did, just as the COVID-19 pandemic has hit some countries much harder than it hit China.

And yet not many countries around the world sought to single out the US for presiding over a massively destructive housing bubble, even though the scars from that previous crisis are still visible. On the contrary, many welcomed the US economy’s return to sustained growth in recent years, because a strong US economy benefits the rest of the world.

So, rather than applying a double standard and fixating on China’s undoubtedly large errors, we would do better to consider what China can teach us. Specifically, we should be focused on better understanding the technologies and diagnostic techniques that China used to keep its - apparent - death toll so low compared to other countries, and to restart parts of its economy within weeks of the height of the outbreak.

And for our own sakes, we also should be considering what policies China could adopt to put itself back on a path toward 6% annual growth, because the Chinese economy inevitably will play a significant role in the global recovery.

If China’s post-pandemic growth model makes good on its leaders’ efforts in recent years to boost domestic consumption and imports from the rest of the world, we will all be better off.

Avoiding a Virus-Induced Cold War with China

17 April 2020

Robin Niblett

Director and Chief Executive, Chatham House
Managing relations with China once the COVID-19 crisis abates will be one of the biggest challenges facing political leaders in the United States and Europe – two of the areas worst-hit by the virus that originated in China.

2020-04-17-Trump-Xi

So far, there has been a noticeable worsening of relations that had already soured in recent years – the latest step being President Donald Trump’s suspension of US funding for the World Health Organization (WHO) in response to accusations of Chinese interference in its operations.

Should the world now simply prepare for a period of intense and extended hostility? As director of a policy institute founded 100 years ago in the shadow of the First World War, I believe we must do all in our power to avoid a return of the global strategic rivalries that blighted the 20th century.

Deepening suspicions

Of course, the outcome does not lie only in the hands of the US and Europe. In the 1930s, as much as they wanted to avoid another great war, British and French leaders were forced to respond to Germany’s aggression in central Europe. In the late 1940s, America’s instinct to disentangle itself from war-ravaged Europe was quickly tempered by the realization that the Soviet Union would impose or infiltrate Communist control as far into Europe as possible.

Today, those who warned that China - a one-party, surveillance state with a power-centralising leader - could never be treated as a global stakeholder feel vindicated. They see in COVID-19 an opportunity to harden policies towards China, starting by blocking all Chinese investment into 5G infrastructure and breaking international dependence on Chinese supply chains.

They can point to the fact that Chinese Communist Party officials in Wuhan initially prioritised sustaining economic growth and supressed reports about COVID-19’s capacity for human-to-human transmission, epitomised by their treatment of Dr Li Wenliang. They can highlight how Beijing’s obsession with denying Taiwan a voice in the WHO prevented Taiwanese input into the early analysis of the crisis. They can highlight the ways in which Beijing has instrumentalised its medical support for coronavirus-afflicted countries for diplomatic gain.

For their part, those in China who believed the US and Europe would never allow China’s return as a regional and world power see this criticism as further evidence. They can point to comments about this being the ‘Chinese virus’, a leaked biological weapon or China’s ‘Chernobyl moment’. ‘Wolf warrior’ Chinese diplomats have sought to outdo each other by challenging narratives about COVID-19, while propagating disinformation about the origins of the virus.

There are major risks if this blame game escalates, as it could in the lead-up to a fraught US presidential election. First, consciously uncoupling the US economically from China will make the post-coronavirus recovery that much harder. China already accounts for nearly 20% of world GDP but, unlike after the global financial crisis in 2008, it is fast becoming the world’s leading consumer market. Its financial stimulus measures need to be closely coordinated with the G7 and through the G20.

Second, Chinese scientists were the first to uncover the genetic code of the virus and shared it with the WHO as early as January 12, enabling the roll-out of effective testing around the world. They are now involved in the global search for a vaccine alongside American and European counterparts. While the Chinese government will remain a legitimate target for criticism, Chinese citizens and companies will contribute to many of the most important technical breakthroughs this century.

Third, if COVID-19 creates a long-term schism between China and the US, with Europeans caught on its edge, this could do deep damage to world order. China may become a less willing partner in lowering global greenhouse gas emissions and sharing renewable energy technologies; in helping African and other developing countries grow sustainably; and in helping to build a more resilient global health infrastructure.

Getting the balance right

But the COVID-19 crisis can also be the hinge point to a more coherent and self-interested transatlantic approach to China, one whose motto should be ‘beware but engage’. There should indeed be limits on state-backed Chinese investment in strategic US and European economic sectors, just as China limits Western access to its market. But the goal should be to lower barriers to trade and investment over time on a mutually beneficial and transparent basis, not to recreate an economic Cold War.

Chinese human rights violations, at home and abroad, should be called out. The dissemination of Chinese systems of citizen surveillance, which will be more popular in a post-coronavirus world, should be monitored and contested with US and European alternatives. And the extent of Chinese exports’ access to international markets should be conditional on China improving its phytosanitary standards - which protect humans, animals, and plants from diseases, pests, or contaminants - and strictly regulating unhygienic wet markets.

But to go further and try to make disengagement the dominant transatlantic policy as COVID-19 subsides will not only divide Europe and America. It will also contribute to a self-fulfilling prophecy; in which a resentful China grows apart from the US and Europe during a period where they must work together.

Given that it will likely be the world’s largest economy in 2030, how the US and Europe manage their relations with China after this crisis is a question at least as seminal as the one they faced after 1945 with the Soviet Union. In the ensuing years, the Soviet Union became a military superpower and competitor, but not an economic one. Containment was a viable, correct and, ultimately, successful strategy. The same options are not available this time. There will be no winners from a new Cold War with China.

WHO Can Do Better - But Halting Funding is No Answer

20 April 2020

Dr Charles Clift

Senior Consulting Fellow, Global Health Programme
Calling a halt to funding for an unspecified time is an unsatisfactory halfway house for the World Health Organization (WHO) to deal with. But with Congress and several US agencies heavily involved, whether a halt is even feasible is under question.

2020-04-20-PPE-Ethiopia-WHO

Donald Trump is impulsive. His sudden decision to stop funding the World Health Organization (WHO) just days after calling it 'very China-centric” and 'wrong about a lot of things' is the latest example. And this in the midst of the worst pandemic since Spanish flu in 1918 and a looming economic crisis compared by some to the 1930s. 

But the decision is not really just about what WHO might or might not have done wrong. It is more about the ongoing geopolitical wrangle between the US and China, and about diverting attention from US failings in its own response to coronavirus in the run-up to the US presidential election.

It clearly also derives from Trump’s deep antipathy to almost any multilateral organization. WHO has been chosen as the fall guy in this political maelstrom in a way that might please Trump’s supporters who will have read or heard little about WHO’s role in tackling this crisis. And the decision has been widely condemned in almost all other countries and by many in the US.

What is it likely to mean in practice for WHO?

Calling a halt to funding for an unspecified time is an unsatisfactory halfway house. A so-called factsheet put out by the White House talks about the reforms it thinks necessary 'before the organization can be trusted again'. 

This rather implies that the US wants to remain a member of WHO if it can achieve the changes it wants. Whether those changes are feasible is another question — they include holding member states accountable for accurate data-sharing and countering what is referred to as 'China’s outsize influence on the organization'. Trump said the funding halt would last while WHO’s mismanagement of the coronavirus pandemic was investigated, which would take 60-90 days. 

The US is the single largest funder of WHO, providing about 16% of its budget. It provides funds to WHO in two ways. The first is the assessed contribution — the subscription each country pays to be a member. In 2018/19 the US contribution should have been $237 million but, as of January this year it was in arrears by about $200 million.

Much bigger are US voluntary contributions provided to WHO for specified activities amounting in the same period to another $650 million. These are for a wide variety of projects — more than one-quarter goes to polio eradication, but a significant portion also is for WHO’s emergency work. 

The US assessed contribution represents only 4% of WHO’s budget. Losing that would certainly be a blow to WHO but a manageable one. Given the arrears situation it is not certain that the US would have paid any of this in the next three months in any case. 

More serious would be losing the US voluntary contributions which account for about another 12% of WHO’s budget—but whether this could be halted all at once is very unclear. First Congress allocates funds in the US, not the president, raising questions about how a halt could be engineered domestically.

Secondly, US contributions to WHO come from about ten different US government agencies, such as the National Institutes of Health or USAID, each of whom have separate agreements with WHO. Will they be prepared to cut funding for ongoing projects with WHO? And does the US want to disrupt ongoing programmes such as polio eradication and, indeed, emergency response which contribute to saving lives? 

Given the president’s ability to do 180 degree U-turns we shall have to wait and see what will actually happen in the medium term. If it presages the US leaving WHO, this would only facilitate growing Chinese influence in the WHO and other UN bodies. Perhaps in the end wiser advice will be heeded and a viable solution found.

Most of President Trump’s criticisms of WHO do not bear close scrutiny. WHO may have made mistakes — it may have given too much credence to information coming from the Chinese. China has just announced that the death toll in Wuhan was 50% higher than previously revealed. It may have overpraised China’s performance and system, but this was part of a deliberate strategy to secure China’s active collaboration so that it could help other countries learn from China’s experience. 

The chief message from this sorry story is that two countries are using WHO as a pawn in pursuing their respective political agendas which encompass issues well beyond the pandemic. China has been very successful in gaining WHO’s seal of approval, in spite of concerns about events prior to it declaring the problem to the WHO and the world. This, in turn, has invited retaliation from the US. 

When this is over will be the time to learn lessons about what WHO should have done better. But China, the US, and the global community of nations also need to consider their own responsibility in contributing to this terrible unfolding tragedy.

Making Movies Come Alive

Many movie animation techniques are based on mathematics. Characters, background, and motion are all created using software that combines pixels into geometric shapes which are stored and manipulated using the mathematics of computer graphics. Software encodes features that are important to the eye, like position, motion, color, and texture, into each pixel. The software uses vectors, matrices, and polygonal approximations to curved surfaces to determine the shade of each pixel. Each frame in a computer-generated film has over two million pixels and can have over forty million polygons. The tremendous number of calculations involved makes computers necessary, but without mathematics the computers wouldn.t know what to calculate. Said one animator, ". . . it.s all controlled by math . . . all those little X,Y.s, and Z.s that you had in school - oh my gosh, suddenly they all apply."

Targeting Tumors

Detection and treatment of cancer have progressed, but neither is as precise as doctors would like. For example, tumors can change shape or location between pre-operative diagnosis and treatment so that radiation is aimed at a target which may have moved. Geometry, partial differential equations, and integer linear programming are three areas of mathematics used to process data in real-time, which allows doctors to inflict maximum damage to the tumor, with minimum damage to healthy tissue. One promising area of investigation is virotherapy: using viruses to destroy cancerous cells. Researchers are using mathematical models to discover how to use the viruses most beneficially.The models provide numerical outcomes for each of the many possibilities, thereby eliminating unsuccessful approaches and identifying candidates for further experimentation.Testing by simulation, which led to the development of anti-HIV cocktails, means good medicine is developed faster and cheaper than it can be by lab experiments and clinical trials alone.

Predicting Storm Surge

Storm surge is often the most devastating part of a hurricane. Mathematical models used to predict surge must incorporate the effects of winds, atmospheric pressure, tides, waves and river flows, as well as the geometry and topography of the coastal ocean and the adjacent floodplain. Equations from fluid dynamics describe the movement of water, but most often such huge systems of equations need to be solved by numerical analysis in order to better forecast where potential flooding will occur. Much of the detailed geometry and topography on or near a coast require very fine precision to model, while other regions such as large open expanses of deep water can typically be solved with much coarser resolution. So using one scale throughout either has too much data to be feasible or is not very predictive in the area of greatest concern, the coastal floodplain. Researchers solve this problem by using an unstructured grid size that adapts to the relevant regions and allows for coupling of the information from the ocean to the coast and inland. The model was very accurate in tests of historical storms in southern Louisiana and is being used to design better and safer levees in the region and to evaluate the safety of all coastal regions.

Pinpointing Style

Mathematics is not just numbers and brute force calculation there is considerable art and elegance to the subject. So it is natural that mathematics is now being used to analyze artists. styles and to help determine the identities of the creators of disputed works. Attempts at measuring style began with literature based on statistics of word use and have successfully identified disputed works such as some of The Federalist Papers. But drawings and paintings resisted quantification until very recently. In the case of Jackson Pollock, his paintings have a demonstrated complexity to them (corresponding to a fractal dimension between 1 and 2) that distinguishes them from simple random drips. A team examining digital photos of drawings used modern mathematical transforms known as wavelets to quantify attributes of a collection of 16th century master.s drawings. The analysis revealed measurable differences between authentic drawings and imitations, clustering the former away from the latter. This is an impressive feat for the non-experts and their model, yet the team agrees that its work, like mathematics itself, is not designed to replace humans, but to assist them.

Putting Music on the Map

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.

Finding Fake Photos

Actually, they weren.t caught together at all their images were put together with software. The shadows cast by the stars. faces give it away: The sun is coming from two different directions on the same beach! More elaborate digital doctoring is detected with mathematics. Calculus, linear algebra, and statistics are especially useful in determining when a portion of one image has been copied to another or when part of an image has been replaced. Tampering with an image leaves statistical traces in the file. For example, if a person is removed from an image and replaced with part of the background, then two different parts of the resulting file will be identical. The difficulty with exposing this type of alteration is that both the location of the replacement and its size are unknown beforehand. One successful algorithm finds these repetitions by first sorting small regions according to their digital color similarity, and then moving to larger regions that contain similar small ones. The algorithm.s designer, a leading digital forensics expert, admits that image alterers generally stay a step ahead of detectors, but observes that forensic advances have made it much harder for them to escape notice. He adds that to catch fakers, At the end of the day you need math.(1) For More Information: Can Digital Photos be Trusted?, Steve Casimiro, Popular Science, October 2005. _______ 1 It May Look Authentic; Here.s How to Tell It Isn't, Nicholas Wade, The New York Times, January 24, 2006.

Folding for Fun and Function

Origami paper-folding may not seem like a subject for mathematical investigation or one with sophisticated applications, yet anyone who has tried to fold a road map or wrap a present knows that origami is no trivial matter. Mathematicians, computer scientists, and engineers have recently discovered that this centuries-old subject can be used to solve many modern problems.The methods of origami are now used to fold objects such as automobile air bags and huge space telescopes efficiently, and may be related to how proteins fold. Manufacturers often want to make a product out of a single piece of material. The manufacturing problem then becomes one of deciding whether a shape can be folded and if so, is there an efficient way to find a good fold? Thus, many origami research problems have to do with algorithm complexity and optimization theory. A testament to the diversity of origami, as well as the power of mathematics, is its applicability to problems at the molecular level, in manufacturing, and in outer space.

Making Votes Count

The outcome of elections that offer more than two alternatives but with no preference by a majority, is determined more by the voting procedure used than by the votes themselves. Mathematicians have shown that in such elections, illogical results are more likely than not. For example, the majority of this group want to go to a warm place, but the South Pole is the group.s plurality winner. So if these people choose their group.s vacation destination in the same way most elections are conducted, they will all go to the South Pole and six people will be disappointed, if not frostbitten. Elections in which only the top preference of each voter is counted are equivalent to a school choosing its best student based only on the number of A.s earned. The inequity of such a situation has led to the development of other voting methods. In one method, points are assigned to choices, just as they are to grades. Using this procedure, these people will vacation in a warm place a more desirable conclusion for the group. Mathematicians study voting methods in hopes of finding equitable procedures, so that no one is unfairly left out in the cold.

Unearthing Power Lines

Votes are cast by the full membership in each house of Congress, but much of the important maneuvering occurs in committees. Graph theory and linear algebra are two mathematics subjects that have revealed a level of organization in Congress groups of committees above the known levels of subcommittees and committees. The result is based on strong connections between certain committees that can be detected by examining their memberships, but which were virtually unknown until uncovered by mathematical analysis. Mathematics has also been applied to individual congressional voting records. Each legislator.s record is represented in a matrix whose larger dimension is the number of votes cast (which in a House term is approximately 1000). Using eigenvalues and eigenvectors, researchers have shown that the entire collection of votes for a particular Congress can be approximated very well by a two-dimensional space. Thus, for example, in almost all cases the success or failure of a bill can be predicted from information derived from two coordinates. Consequently it turns out that some of the values important in Washington are, in fact, eigenvalues. For More Information: Porter, Mason A; Mucha, Peter J.; Newman, M. E.

Tripping the Light-Fantastic

Invisibility is no longer confined to fiction. In a recent experiment, microwaves were bent around a cylinder and returned to their original trajectories, rendering the cylinder almost invisible at those wavelengths. This doesn't mean that we're ready for invisible humans (or spaceships), but by using Maxwell's equations, which are partial differential equations fundamental to electromagnetics, mathematicians have demonstrated that in some simple cases not seeing is believing, too. Part of this successful demonstration of invisibility is due to metamaterials electromagnetic materials that can be made to have highly unusual properties. Another ingredient is a mathematical transformation that stretches a point into a ball, "cloaking" whatever is inside. This transformation was discovered while researchers were pondering how a tumor could escape detection. Their attempts to improve visibility eventually led to the development of equations for invisibility. A more recent transformation creates an optical "wormhole," which tricks electromagnetic waves into behaving as if the topology of space has changed. We'll finish with this: For More Information: Metamaterial Electromagnetic Cloak at Microwave Frequencies, D. Schurig et al, Science, November 10, 2006.

Bending It Like Bernoulli

The colored "strings" you see represent air flow around the soccer ball, with the dark blue streams behind the ball signifying a low-pressure wake. Computational fluid dynamics and wind tunnel experiments have shown that there is a transition point between smooth and turbulent flow at around 30 mph, which can dramatically change the path of a kick approaching the net as its speed decreases through the transition point. Players taking free-kicks need not be mathematicians to score, but knowing the results obtained from mathematical facts can help players devise better strategies. The behavior of a ball depends on its surface design as well as on how it.s kicked. Topology, algebra, and geometry are all important to determine suitable shapes, and modeling helps determine desirable ones. The researchers studying soccer ball trajectories incorporate into their mathematical models not only the pattern of a new ball, but also details right down to the seams. Recently there was a radical change from the long-used pentagon-hexagon pattern to the adidas +TeamgeistTM. Yet the overall framework for the design process remains the same: to approximate a sphere, within less than two percent, using two-dimensional panels.

Going with the Floes - Part 4

Sea ice is one of the least understood components of our climate. Naturally its abundance or scarcity is a telling sign of climate change, but sea ice is also an important actor in change as well, insulating the ocean and reflecting sunlight. A branch of mathematics called percolation theory helps explain how salt water travels through sea ice, a process that is crucial both to the amount of sea ice present and to the microscopic communities that sustain polar ecosystems. By taking samples, doing on-site experiments, and then incorporating the data into models of porous materials, mathematicians are working to understand sea ice and help refine climate predictions. Using probability, numerical analysis, and partial differential equations, researchers have recently shown that the permeability of sea ice is similar to that of some sedimentary rocks in the earth.s crust, even though the substances are otherwise dissimilar. One major difference between the two is the drastic changes in permeability of sea ice, from total blockage to clear passage, that occur over a range of just a few degrees. This difference can have a major effect on measurements by satellite, which provide information on the extent and thickness of sea ice. Results about sea ice will not only make satellite measurements more reliable, but they can also be applied to descriptions of lung and bone porosity, and to understanding ice on other planets.

Hearing a Master.s Voice

The spools of wire below contain the only known live recording of the legendary folk singer Woody Guthrie. A mathematician, Kevin Short, was part of a team that used signal processing techniques associated with chaotic music compression to recapture the live performance, which was often completely unintelligible. The modern techniques employed, instead of resulting in a cold, digital output, actually retained the original concert.s warmth and depth. As a result, Short and the team received a Grammy Award for their remarkable restoration of the recording. To begin the restoration the wire had to be manually pulled through a playback device and converted to a digital format. Since the pulling speed wasn.t constant there was distortion in the sound, frequently quite considerable. Algorithms corrected for the speed variations and reconfigured the sound waves to their original shape by using a background noise with a known frequency as a "clock." This clever correction also relied on sampling the sound selectively, and reconstructing and resampling the music between samples. Mathematics did more than help recreate a performance lost for almost 60 years: These methods are used to digitize treasured tapes of audiophiles everywhere.

Steering Towards Efficiency

The racing team is just as important to a car.s finish as the driver is. With little to separate competitors over hundreds of laps, teams search for any technological edge that will propel them to Victory Lane. Of special use today is computational fluid dynamics, which is used to predict airflow over a car, both alone and in relation to other cars (for example, when drafting). Engineers also rely on more basic subjects, such as calculus and geometry, to improve their cars. In fact, one racing team engineer said of his calculus and physics teachers, the classes they taught to this day were the most important classes I.ve ever taken.(1) Mathematics helps the performance and efficiency of non-NASCAR vehicles, as well. To improve engine performance, data must be collected and processed very rapidly so that control devices can make adjustments to significant quantities such as air/fuel ratios. Innovative sampling techniques make this real-time data collection and processing possible. This makes for lower emissions and improved fuel economy goals worthy of a checkered flag.

Improving Stents - Part 2

Stents are expandable tubes that are inserted into blocked or damaged blood vessels. They offer a practical way to treat coronary artery disease, repairing vessels and keeping them open so that blood can flow freely. When stents work, they are a great alternative to radical surgery, but they can deteriorate or become dislodged. Mathematical models of blood vessels and stents are helping to determine better shapes and materials for the tubes. These models are so accurate that the FDA is considering requiring mathematical modeling in the design of stents before any further testing is done, to reduce the need for expensive experimentation. Precise modeling of the entire human vascular system is far beyond the reach of current computational power, so researchers focus their detailed models on small subsections, which are coupled with simpler models of the rest of the system. The Navier-Stokes equations are used to represent the flow of blood and its interaction with vessel walls. A mathematical proof was the central part of recent research that led to the abandonment of one type of stent and the design of better ones. The goal now is to create better computational fluid-vessel models and stent models to improve the treatment and prediction of coronary artery disease the major cause of heart attacks.

Restoring Genius - Discovering lost works of Archimedes - Part 2

Archimedes was one of the most brilliant people ever, on a par with Einstein and Newton. Yet very little of what he wrote still exists because of the passage of time, and because many copies of his works were erased and the cleaned pages were used again. One of those written-over works (called a palimpsest) has resurfaced, and advanced digital imaging techniques using statistics and linear algebra have revealed his previously unknown discoveries in combinatorics and calculus. This leads to a question that would stump even Archimedes: How much further would mathematics and science have progressed had these discoveries not been erased? One of the most dramatic revelations of Archimedes. work was done using X-ray fluorescence. A painting, forged in the 1940s by one of the book.s former owners, obscured the original text, but X-rays penetrated the painting and highlighted the iron in the ancient ink, revealing a page of Archimedes. treatise The Method of Mechanical Theorems. The entire process of uncovering this and his other ideas is made possible by modern mathematics and physics, which are built on his discoveries and techniques. This completion of a circle of progress is entirely appropriate since one of Archimedes. accomplishments that wasn.t lost is his approximation of pi.

Getting It Together

The collective motion of many groups of animals can be stunning. Flocks of birds and schools of fish are able to remain cohesive, find food, and avoid predators without leaders and without awareness of all but a few other members in their groups. Research using vector analysis and statistics has led to the discovery of simple principles, such as members maintaining a minimum distance between neighbors while still aligning with them, which help explain shapes such as the one below. Although collective motion by groups of animals is often beautiful, it can be costly as well: Destructive locusts affect ten percent of the world.s population. Many other animals exhibit group dynamics; some organisms involved are small while their groups are huge, so researchers. models have to account for distances on vastly different scales. The resulting equations then must be solved numerically, because of the incredible number of animals represented. Conclusions from this research will help manage destructive insects, such as locusts, as well as help speed the movement of people.ants rarely get stuck in traffic.

Working It Out. Math solves a mystery about the opening of "A Hard Day's Night."

The music of most hit songs is pretty well known, but sometimes there are mysteries. One question that remained unanswered for over forty years is: What instrumentation and notes make up the opening chord of the Beatles. "A Hard Day.s Night"? Mathematician Jason Brown - a big Beatles fan - recently solved the puzzle using his musical knowledge and discrete Fourier transforms, mathematical transformations that help decompose signals into their basic parts. These transformations simplify applications ranging from signal processing to multiplying large numbers, so that a researcher doesn.t have to be "working like a dog" to get an answer. Brown is also using mathematics, specifically graph theory, to discover who wrote "In My Life," which both Lennon and McCartney claimed to have written. In his graphs, chords are represented by points that are connected when one chord immediately follows another. When all songs with known authorship are diagrammed, Brown will see which collection of graphs - McCartney.s or Lennon.s - is a better fit for "In My Life." Although it may seem a bit counterintuitive to use mathematics to learn more about a revolutionary band, these analytical methods identify and uncover compositional principles inherent in some of the best Beatles. music. Thus it.s completely natural and rewarding to apply mathematics to the Fab 4 For More Information: Professor Uses Mathematics to Decode Beatles Tunes, "The Wall Street Journal", January 30, 2009..

Pulling Out (from) All the Stops - Visiting all of NY's subway stops in record time

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.

Matching Vital Needs - Increasing the number of live-donor kidney transplants

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.

Predicting Climate - Part 2

What.s in store for our climate and us? It.s an extraordinarily complex question whose answer requires physics, chemistry, earth science, and mathematics (among other subjects) along with massive computing power. Mathematicians use partial differential equations to model the movement of the atmosphere; dynamical systems to describe the feedback between land, ocean, air, and ice; and statistics to quantify the uncertainty of current projections. Although there is some discrepancy among different climate forecasts, researchers all agree on the tremendous need for people to join this effort and create new approaches to help understand our climate. It.s impossible to predict the weather even two weeks in advance, because almost identical sets of temperature, pressure, etc. can in just a few days result in drastically different weather. So how can anyone make a prediction about long-term climate? The answer is that climate is an average of weather conditions. In the same way that good predictions about the average height of 100 people can be made without knowing the height of any one person, forecasts of climate years into the future are feasible without being able to predict the conditions on a particular day. The challenge now is to gather more data and use subjects such as fluid dynamics and numerical methods to extend today.s 20-year projections forward to the next 100 years.

Resisting the Spread of Disease - Part 2

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.
