change K2 will not be made available for Joomla 4/5 - change of course By www.joomlaworks.net Published On :: Thu, 30 May 2024 20:56:11 +0300 The writing's on the wall. Joomla 4 and 5 are failed CMS releases. They account for around 0.3% of ALL Joomla sites according to W3Techs (https://w3techs.com/technologies/details/cm-joomla). Joomla's official stats (which were introduced near the end of life of Joomla 3 - https://developer.joomla.org/about/stats.html) are far less accurate obviously (e.g. they don't account for Joomla 1.5 > 2.5 sites or older Joomla 3 releases) but still show around 10% of sites use Joomla 4/5, after 3 years of their release. And these stats can be disabled by users of Joomla sites (most do). This means adoption for these versions is close to non-existent. A sad reality, but an understandable one (read my posts on May 30th at https://x.com/joomlaworks for additional context). There is literally nothing to say about how things have evolved for Joomla. At this rate, it will probably be a dead software project within the next couple of years. It's not just the users that are de-motivated, it's the developers too (the Joomla core developers). Few people will enjoy working on Joomla if no one uses it. It just makes sense. As such, and given that we're strongly invested in Joomla 3 (in some of the largest news/media site implementations worldwide with Joomla), we don't plan on giving up on K2 (or Joomla 3). In fact, our goal is to pivot and work on a possible fork, unless a miracle happens and the Joomla core team gets their shit together and works on a true/seamless Joomla 3 to Joomla 5 (or 6?) upgrade. The fork is a reasonable path for us for many reasons but I'd list the following ones here (for now): It'll be exciting to go from K2 (a "half" CMS so to speak) to a full CMS. Any crap that didn't work or half-worked on J3 will be fixed. Sky's the limit. Really. No stupid politics, irrelevant conventions, idiotic patterns to follow. We have a clear goal for K2 (and Joomla) and that's what we're gonna work on. That goal is a fast, reliable. modern CMS that leaves people asking "why WordPress?" Some will nag Joomla 3 uses old code. No it doesn't. It uses a certain design that was popular at the time it was introduced. The only change that is required is for it to be updated so it catches up with PHP's latest versions (for the record, we actively run sites with Joomla 3 / K2 on PHP 8.2). It's a mature code base that can be gradually improved. The fork could be introduced in 2 phases. Phase 1: A re-branding for existing sites to move over their content from com_content to K2 (far less work than switching to Joomla 4/5) and existing Joomla/K2 sites to freshen up their backend. Phase 2: This would be the part we lighten up the core. This means com_content & components like banners, newsfeeds, messages etc., their respective modules and plugins and generally other accumulated crap (like User Notes) that literally noone ever used will be stripped off Joomla. Either way K2 can reproduce most of these stuff far better. Any design changes will be subtle and NOT affect existing Joomla extensions that respected the Joomla UI design. It will also certainly NOT affect extensions that brought in their own design/MVC and so on (think AcyMailing, page builders etc. etc.). If our friend Ryan provides his blessing, we would also love to swap the current Joomla WYSIWYG editor with JCE Core. If not, it's always available either way. We will just upgrade TinyMCE and still install our beloved JCE. This would also be a good time to standardize things like "editor xtd" buttons in a way that they better integrate with the WYSIWYG editor... Features and custom extensions we've used for large scale projects could be integrated in the new CMS, if it makes sense for most users to have. E.g. fast search powered by Elasticsearch is a no-brainer (and we can throw that Smart Search crap out for good). The point is to do something that's fun, while professional at the same time. Backward compatibility will be our holy grail. Anyone that tells it can't are either lazy or just plain bad programmers (hell, we've maintained K2 for Joomla 1.5 to 3 for 15 damn years). We're already in touch with partners to finance this move. On the long term, all we need is a couple of devs, working full time. The next big phase will be infrastructure as required for any modern CMS. That means rebuilding something like the JED, working on documenting use and code etc. At the same time, it's practical to keep everything to a minimum. E.g. there is no reason to use our own forum, but probably go for something like GitHub so we can have everything in a single place: code and discussion, coupled with solid anti-spam (cause let's face it, that's what forums suffer from these days). By keeping things lean and simple, we will work less on infrastructure and more on the CMS's code and features. If you ask "why now", I can respond with 2 things: 1) There's been plenty of time for people to switch to Joomla 4/5. Very few did. 2) It's MUCH worse waiting things out to chart their predefined course than actually fucking doing something about it, even if it fails or doesn't work out. Follow up blog posts will provide more insight into how things will play out in the coming months and how others can join this effort. P.S.

change Digital politics threatens democracy and must change By www.chathamhouse.org Published On :: Fri, 13 Jan 2023 16:08:06 +0000 Digital politics threatens democracy and must change Expert comment NCapeling 13 January 2023 Violence in Brazil has again brought into focus the need for technology platforms to prioritize social responsibility to help prevent anti-democratic action. Immediately following the violent storming of Brazil’s congressional building, supreme court, and presidential palace, comparisons to the infamous events of 6 January 2021 in the US came quickly and easily – and with good reason. Both Donald Trump and Jair Bolsonaro built a fervent – albeit inchoate – political base of grievance which included Christian evangelicals, gun enthusiasts, and the disenfranchised. Both cynically spread doubts about the election victories of their successors without evidence. And it has been claimed both incited their supporters to overturn these results. But this list of similarities extend beyond mere politics. The attack on democracy in Brazil was recorded, amplified, coordinated, and funded by exactly the same technologies used by the protesters in the US on 6 January. In Brazil, the main engines of misinformation and insurrection planning were Telegram, Facebook, and WhatsApp, although some election-denying diehards also shifted to Twitter. Tactical use of social media to mobilize and fundraise When Bolsonaro was originally elected in 2018, these platforms were already a medium for promoting disinformation, conspiracy, and fear. But in the lead-up to the violence of 8 January, they became a means by which ‘Bolsonaristas’ raised funding for an attack and mobilized supporters to come to Brasilia – advertising the availability of buses and even free food for marchers – using the Festa da Selma hashtag. Well-intentioned regulation will fall short so long as it is narrowly focused on a never-ending game of ‘content whack-a-mole’ and is hamstrung by powerful voices To avoid detection by authorities, organizers used a simple switch of the letter ‘v’ to ‘m’ so that Selva, meaning ‘jungle’, became Selma – which means ‘party in the jungle’ to those in the know. But the authorities in the Brasilia state of Distrito Federal appeared to care little about preventing the attack anyway. Civil society organizations have warned for decades that policies made in a Silicon Valley boardroom fit poorly to the realities of countries such as Brazil, Somalia, or Myanmar. Content moderation is a near-impossible task at the scale demanded by platforms as vast as those operated by big tech, and automated solutions are far from being a silver bullet as they create as many problems as they solve. Extremism has found an unfettered enabler on mainstream platforms, and an increasingly sprawling network of alternative tech has made such voices resilient to challenge. Platforms such as Gettr, Gab, and Telegram have become go-to platforms for extremist networks when fringe voices find themselves blocked by mainstream platforms. Telegram has come under significant scrutiny for the role it played in the storming of Congress in Brasilia but any number of tools and platforms – each with millions of users – could have achieved similar results. The sordid events in Brasilia are just the latest chapter in digital extremism and conspiracy- mongering which often erupts into anti-democratic violence, and should serve as a reminder of the urgent risks of disinformation and the role digital technology plays in inciting, coordinating, fundraising, and amplifying such events. But the checks on the power of private social media companies are still few and splintered. In Brazil, Supreme Court Justice Alexandre de Moraes, head of the elections tribunal, attempted to crack down on social media, banning users for spreading misinformation in a move which sparked complaints of censorship from Bolsonaro supporters. Following the elections, Moraes has advocated for greater judicial authority to regulate social media – but the justice is only one person and his impartiality is already being challenged given his aggressive pursuit of Bolsonaro supporters posting inflammatory messages. And one justice doing it alone only inflames an already volatile situation. Effective regulation of social media requires an independent body vested with multiparty support and operating under clearly-defined rules and authority. A global movement to find solutions Brazil is not alone in an increasingly frantic search for checks on digital power as dozens of regulatory regimes are springing up around the world. All are premised on platforms being responsible for their own fiefdoms, but few tackle the threat posed to democracy by unchecked corporate power over digital commons. Telegram has come under significant scrutiny for the role it played in the storming of Congress in Brasilia but any number of tools and platforms – each with millions of users – could have achieved similar results Well-intentioned regulation will fall short so long as it is narrowly focused on a never-ending game of ‘content whack-a-mole’ and is hamstrung by powerful voices who see any rules as an attack on freedoms of expression or corporate decision-making. Democracies are traditionally cautious in managing speech, in separating good information from bad information, or in defining acceptable politics. The steady watering down of the UK’s Online Safety Bill, now so thin on disinformation as to be essentially homeopathic, shows that democratic regulation is willing to go only so far in tackling challenges posed by digital politics.

change A drug-resistant {beta}-lactamase variant changes the conformation of its active-site proton shuttle to alter substrate specificity and inhibitor potency [Microbiology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Lys234 is one of the residues present in class A β-lactamases that is under selective pressure due to antibiotic use. Located adjacent to proton shuttle residue Ser130, it is suggested to play a role in proton transfer during catalysis of the antibiotics. The mechanism underpinning how substitutions in this position modulate inhibitor efficiency and substrate specificity leading to drug resistance is unclear. The K234R substitution identified in several inhibitor-resistant β-lactamase variants is associated with decreased potency of the inhibitor clavulanic acid, which is used in combination with amoxicillin to overcome β-lactamase–mediated antibiotic resistance. Here we show that for CTX-M-14 β-lactamase, whereas Lys234 is required for hydrolysis of cephalosporins such as cefotaxime, either lysine or arginine is sufficient for hydrolysis of ampicillin. Further, by determining the acylation and deacylation rates for cefotaxime hydrolysis, we show that both rates are fast, and neither is rate-limiting. The K234R substitution causes a 1500-fold decrease in the cefotaxime acylation rate but a 5-fold increase in kcat for ampicillin, suggesting that the K234R enzyme is a good penicillinase but a poor cephalosporinase due to slow acylation. Structural results suggest that the slow acylation by the K234R enzyme is due to a conformational change in Ser130, and this change also leads to decreased inhibition potency of clavulanic acid. Because other inhibitor resistance mutations also act through changes at Ser130 and such changes drastically reduce cephalosporin but not penicillin hydrolysis, we suggest that clavulanic acid paired with an oxyimino-cephalosporin rather than penicillin would impede the evolution of resistance.

change How the world has changed on my watch By www.chathamhouse.org Published On :: Wed, 25 May 2022 09:46:46 +0000 How the world has changed on my watch The World Today mhiggins.drupal 25 May 2022 As Robin Niblett steps down from his role as Director of Chatham House he reflects on the past 15 years of international affairs International relations had resumed a steadier rhythm in January 2007 when I became Director of Chatham House. The aftershock of the 2001 terrorist attacks on the United States and the Bush administration’s contentious responses in Iraq and its ‘global war on terror’ had settled down somewhat. With hindsight, 2007 was the fulcrum between a cautiously optimistic post-Cold War world and the contested environment we live in today That year President George W Bush’s second administration was mending fences with its European allies. China’s GDP growth hit a three-decade peak of 14 per cent, and the idea that this could drive a ‘win-win’ economic cycle did not yet grate. Financial regulators had not woken up to the credit crisis that they had enabled. And the European Union was still obsessed with ‘widening versus deepening’, while Britain tried to have its cake and eat it on the sidelines. With hindsight, 2007 acted as the fulcrum between a cautiously optimistic post-Cold War world and the contested environment we live in today. Russian President Vladimir Putin chose that year’s Munich Security Conference to deliver a tirade against the injustices of a US-led world, with arguments that presaged this year’s invasion of Ukraine. By the start of 2008, Alan Greenspan’s belief in the rationality of financial markets turned out to be a fallacy as US and European banks imploded. The subsequent economic turmoil, followed by monetary easing and fiscal austerity, sowed the seeds for the populist politics that emerged on both sides of the Atlantic. — Robin Niblett with the Queen, Patron of Chatham House, and Sir John Major Nevertheless, world leaders did not give up on the promise of international cooperation. The global financial crisis led to the elevation of the G20 as the premier forum for coordinating global economic policy between the world’s major economies. By 2015, with Barack Obama in the White House, two landmark deals were reached: the Paris Agreement and the Joint Comprehensive Plan of Action, an example of truly global cooperation between all five permanent members of the UN Security Council. The next year, China’s first female chair of the Foreign Affairs Committee of the National People’s Congress, Fu Ying, pointed to a ‘decentralization of world power’ that might lead to a more inclusive world order. But this sense of relative optimism about the future masked two fundamental changes. The first was the erosion of the cohesion of democratic societies under the pressures of globalization and the aftershocks of the financial crisis. Instant access to unintermediated and often manipulated information ended up stimulating and polarizing societies in equal measure, deepening the divide between those searching for the certainties of the past and those open to the uncertainties of a more globalized future. The second change is the end of the global hierarchy that followed the Second World War, in which the US and the West remained at the top, even with the advent of a more polycentric world. This change is driven by several factors, above all the growing economic and technological parity between China and the US, and by America’s schizophrenic response. The Obama administration sought to restore a more inclusive form of global leadership, but it unwittingly revealed the limits of US power by breaking its red lines over Bashir al-Assad’s use of chemical weapons in Syria and by turning a blind eye to China’s takeover of disputed islands in the South China Sea. Donald Trump’s America First policies then flipped the US into an overbearing version of other self-interested powers. After this zigzagging by the US, leaders in the Middle East have developed their own assertive foreign policies, while two nascent democracies in Southeast Asia, Thailand and Myanmar, are again ruled by military juntas. EU leaders became obsessed with the idea of strategic autonomy. And, although Joe Biden’s election was welcomed across most of Europe, it could not assuage concerns about the potentially transitory nature of his claim that ‘America is back’. As I step down, I’m torn between fury at the senseless tragedy of the war in Ukraine and hope that human courage will sustain us Putin has seized on this moment of transatlantic uncertainty and post-Covid navel-gazing to try to create a personal legacy as the leader who reunited a greater Russia out of the rubble of the Soviet Union. Instead, he has united Ukrainians and reunited the world’s liberal democracies in opposition to his brutal invasion and blatant rupture of international law. His actions have also drawn the contours of a new, trilateral international system. Some 40 democracies across North America, Europe and the Indo-Pacific now see Putin and Xi Jinping – given China’s rhetorical support for Putin’s invasion – as interconnected threats to their long-term security. They are organizing to resist, using a re-energized Nato, new structures for Indo-Pacific cooperation and cross-linkages between these two spheres. For their part, Putin and Xi, though not formal allies, are tied together by each one’s need that the other survives and prospers while they are in confrontation with the liberal democracies. The third, largest and most diverse group of countries are the newly non-aligned. India stands proudly in the foreground, but other major democracies such as Brazil, Indonesia and South Africa, and non-democracies such as Egypt and Vietnam, are triangulating strategically between the world’s dominant democratic and authoritarian poles. Multilateral institutions will be weaker as a result. — Portrait of Robin Niblett by Sarah Tanat-Jones Does this more divided world presage major conflict between the great powers? Hopefully not; after all, nuclear weapons remain a potent deterrent. Does global division herald the end of economic globalization and of the international cooperation needed to manage shared global challenges? Not necessarily. While Russia will be excluded from liberal democratic markets for as long as Putin is in the Kremlin, China’s reliance on global markets and the importance of its market to the world make it unlikely that we will return to a new Cold War. Global supply chains and foreign investment will be more tightly circumscribed than today, but they will persist. And international cooperation to combat climate change and manage the environment will continue. Meanwhile, technological innovation will accelerate, opening new prospects for sustainable development and employment, even as it sharpens the facets of geopolitical competition. And we may soon cross the tipping point at which women hold a critical mass of positions of political and community leadership in many parts of the world. Given that male leaders are, once again, the instigators of the latest spasms of violence, a more gender-balanced approach to leadership holds the prospect of greater political stability and more inclusive and sustainable development. As I step down as Chatham House Director, I find myself torn between fury at the senseless human tragedy of a drawn-out war in Ukraine and the way its spillover effects are devastating the welfare of hundreds of millions across the globe, and hope that human courage, resilience and ingenuity will nevertheless sustain us on the path to a better future. I am reassured in this by the knowledge that Chatham House’s researchers, professional staff and increasingly diverse membership mean that it is well placed to help decision-makers and societies navigate this complex world.

To address the alarming increase knife crime, a 10% rise in knife-related homicides between April 2022 and March 2023, the UK government launched a coalition of community leaders, campaigners and policy makers to tackle this tragic loss of life.With people under 25 disproportionately affected, the ‘knife crime epidemic’ represents an example of how youth activist groups are central to tackling the problem. Organisations for and operated by young people form a key part of the strategy to ensure people are better protected from violent crime.Around the world, a network of youth groups are similarly striving to make a difference and build a better life for future generations. Operating in different political and economic conditions, there are learnings to be found in groups working across the world.This session will discuss how grassroot activism and youth organisations can influence governments to prevent young people falling into crime, the role of race and religion, and whether organisations are improving in their effectiveness around the world.This event is a collaboration with Integrate UK.

change The killing of Yahya Sinwar won’t change the course of the Gaza war By www.chathamhouse.org Published On :: Fri, 18 Oct 2024 15:10:40 +0000 The killing of Yahya Sinwar won’t change the course of the Gaza war Expert comment jon.wallace 18 October 2024 Israel has larger ambitions for Gaza beyond the Hamas leader’s death and the armed group is still asserting its influence despite its degradation. After a year of being hunted as one of the most wanted men in the Middle East, Hamas leader Yahya Sinwar was killed by Israeli forces on 17 October, in the city of Rafah in the Gaza Strip.Hailing from Khan Younis refugee camp, Sinwar was imprisoned in Israel in 1989 for the abduction and killing of two Israeli soldiers. He was freed alongside 1,000 other prisoners during a major 2011 exchange, gradually building a notorious reputation as an intelligent and ruthless political figure.As Hamas’ Gaza chief since 2017, Sinwar oversaw the consolidation of the movement’s authoritarian rule in the Strip and co-directed its military confrontations with Israel. He is regarded as a chief architect of Hamas’ deadly assault of 7 October, which killed 1,200 Israelis, mostly civilians, in southern communities. Contrary to some wishful thinking, Sinwar’s death is unlikely to change Israel’s calculus in Gaza. Many world leaders and pundits were quick to embrace Sinwar’s death as an opportunity to press for a ceasefire in Gaza and secure the release of roughly 100 Israeli hostages still held by Hamas and other groups. It is too early to know the full repercussions of this development, but these hopes are largely misplaced – and reflect a reluctance to confront the larger obstacles and motivations that are preventing an end to the war.Morale amid aimlessnessFor Israelis, Sinwar’s death is undoubtedly a morale booster. It is a symbolic victory over a man deemed responsible for the 7 October massacres, and a tactical success that rids Israel of a formidable foe – one who was also an invested ally of Iran and the Axis of Resistance. Israeli politicians and generals will relish the news as another step towards restoring their reputations after their failure to prevent the 7 October attack.Yet contrary to some wishful thinking, Sinwar’s death is unlikely to change Israel’s calculus in Gaza. Prime Minister Benjamin Netanyahu, whose popularity has been slowly recovering in recent months, described the news as ‘the beginning of the end’ but warned that ‘the task before us is not yet complete’.The intensification of Israel’s war with Hezbollah – including a ground invasion of Lebanon, airstrikes across the country, and the displacement of over 1 million people – has shifted Israelis’ focus away from Gaza over the past month, especially as Hezbollah rockets disrupt life in Israel’s central cities as well as the north. The Israeli military – despite its clashes with the prime minister – is seizing the chance to redraw Israel’s geopolitical environment. During that time, the Israeli army has begun a major offensive in the northern part of the Strip, implementing what appears to be the first part of the so-called ‘General’s Plan’ – an operation to besiege and force out roughly 300,000 Palestinian civilians who remain in the area. It could also pave the way for Israel’s absorption of part of the territory. (Israel’s military has denied pursuing the plan).As such, the Israeli government has relegated the importance of the hostages. Netanyahu is eager to divert the public’s frustration with his months-long sabotage of a deal, while the military – despite its clashes with the prime minister – is seizing the chance to redraw Israel’s geopolitical environment. Even if a deal is struck in the wake of Sinwar’s death, Israel’s bombing and carving-up of Gaza and south Lebanon will likely continue.Dynamic but degradedFor Hamas, the killing of its fiery politburo chief – just over two months after the assassination of his predecessor Ismail Haniyeh in Tehran – is certainly a blow to its leadership and internal stability. But the Islamist movement’s dynamism has not changed. Hamas’s decision-making processes are not pegged to specific individuals, and other figures, whether in Gaza or in exile, will be rotated into senior positions. Related content The real schism in the Israel–Hamas ceasefire talks is about who decides Gaza’s future It is unclear whether Hamas will promote a leader who shares Sinwar’s hardline orientation, or drift back to a more moderate figure similar to Haniyeh. Regardless, Hamas’s core demands in any ceasefire and hostage negotiations are unlikely to shift significantly. The movement is still seeking a permanent end to the war, and Israel is still refusing to grant it.Hamas’s military capacity has been severely degraded by the Israeli offensive, not least by the fact that much of Gaza has been made unliveable and ungovernable. But the movement is far from destroyed. Its militants continue to fight a guerrilla war to undermine Israel’s foothold in Gaza, while trying to reassert Hamas control over public order, the war economy, and the distribution of aid.Moreover, as the history of movements like Hamas and Hezbollah shows, the devastating nature of Israel’s campaigns and occupations are planting the seeds for further militancy among Palestinians, whether organized under Hamas or smaller, decentralized groups. The war has brutally decimated Gaza’s society, and the notion that killing figures like Sinwar will dissuade future recruits to fight Israel is fanciful.On the Palestinian political level, Hamas and Fatah are still in talks about forming a unity agreement, though negotiations have so far remained fruitless. Even if a pact is made, Israel’s relentless targeting of Hamas personnel, the perception of the Fatah-led Palestinian Authority (PA) as feckless collaborators, and Palestinians’ feeling of total abandonment raise doubts about the parties’ ability to regain popular support or legitimacy – whether to lead an interim government or the wider national movement.The gravest threatThe killing of Sinwar is a significant marker in the Gaza war, with important ramifications for the movement he led and the conflict he seismically shaped. Israel will portray his death as validation of its aggressive military approach, and a further step in the erosion of Iran’s regional influence – an agenda the US has actively supported. Full Article

change Geopolitical corporate responsibility can drive change By www.chathamhouse.org Published On :: Tue, 26 Jul 2022 12:55:12 +0000 Geopolitical corporate responsibility can drive change Expert comment NCapeling 26 July 2022 Russia’s long invasion of Ukraine is testing the commitment of business, but this could see the emergence of a new pillar of support for the rules-based international order. The massive exit of more than 1,000 international companies from Russia has surpassed – by a factor of nearly ten in merely four months – the number which pulled out of apartheid-led South Africa over an entire decade. These company exits extend beyond those industries targeted for sanctions – oil and gas, banks and financial services, aerospace, and certain technology sectors – to include hundreds in consumer products ranging from Levi’s and H&M clothing to Coca-Cola and McDonalds. Many of these companies may wish to return to a post-conflict – or post-Putin – Russia, while a few have already sold their Russian operations, as McDonald’s has to an existing Siberian licensee. Both reputational and operational factors are driving the huge exodus: reputational as companies have chosen to disassociate themselves from Putin’s regime; operational as transportation routes and supply chains have been interrupted. Few of these companies have made explicit the principles at stake, while many still face ‘tricky legal, operational and ethical considerations’ and some have kept operations in place. But the collective impact of the exit in response to Russia’s affront to international law has sent shockwaves around the world. Current issues and future implications Minds now turn to whether this exodus sets a blueprint for the future, and how companies having to make complex and sensitive risk assessments and global business planning decisions can address both current issues as well as similar future challenges. The new Declaration from the Business for Ukraine Coalition – an international civil society initiative of organizations and individuals – encourages companies to reinforce ‘responsible exit’ from Russia ‘in response to its unprovoked, full-scale war on Ukraine’. The declaration’s objective is to ‘block access to the economic and financial resources enabling Russian aggression’ and it urgently calls on companies that have terminated or suspended their business operations and relationships to ‘stand by those commitments until the territorial sovereignty of Ukraine within internationally recognized borders is restored.’ Business has a fundamental stake in the international order as the framework for stability, prosperity, open societies, and markets It also states companies yet to terminate or suspend operations in Russia should do so unless they can demonstrate through due diligence that their provision of ‘essential’ services or products – such as medicines – meet critical humanitarian needs. The 2022 Edelman Trust Barometer Special Report: The Geopolitical Business suggests Ukraine represents an inflection point posing ‘a new test’ for business. According to an online survey of 14,000 respondents in 14 countries, including employees, NGOs, and other stakeholders, there is a ‘rising call’ for business to be more engaged in geopolitics, with CEOs ‘expected to shape policy’ on societal and geopolitical issues. Such expectations have been intensifying with the impetus of the combined stakeholder capitalism and corporate purpose agenda, even as a political backlash in the US against the environmental, social, and governance (ESG) movement linking institutional investors and multinational corporations gains momentum. The emergence of corporate activism is a further development – partly driven by employees and accelerated during the pandemic – on issues of economic inequality, racial injustice, and gender equality, as well as the climate crisis. When considering what broader purpose should drive this corporate geopolitical engagement, the Business for Ukraine Declaration offers an answer, calling Russia’s aggression ‘an attack on the rules-based international order which must be protected to ‘safeguard the international community and the global economy.’ This points to broader interests and values at stake in the Russian war on Ukraine because supporting the rules-based international order can become the basis of a new geopolitical corporate responsibility. Business, especially multinational corporations and institutional investors, fundamentally depend on and have enormously benefitted from this order. Economic development needs a stable rules-based international order Trade and investment, entrepreneurship, and innovation – the sinews of economic development – depend on predictable, rational behaviour by states at home and abroad. Individual companies and entire industries share a stake in upholding this order at a time when its stability and even legitimacy is undergoing a severe challenge. A new geopolitical corporate responsibility does not need to become a doctrine but can instead be an agenda to support the international rules-based order under stress The rules-based international order has evolved since the adoption of the UN Charter in 1945, the Universal Declaration of Human Rights in 1948, and the establishment of the standards, norms and institutions that reflect and reinforce these lodestars. It defines the international community, the rule of law, accountable governance, civic freedoms, and human rights within nations. It also supports national self-determination, sovereignty, and the disavowal of the use of force to alter borders among nations, and it provides accountability for genocide, crimes against humanity, and war crimes. Business has a fundamental stake in the international order as the framework for stability, prosperity, open societies, and markets. A new geopolitical corporate responsibility does not need to become a doctrine but can instead be an agenda to support the international rules-based order under stress. Such an agenda may help multinationals deal with expectations they already face, such as: Avoiding situations where they cause, contribute, or are directly linked to human rights abuses. This objective is enshrined in the UN Guiding Principles on Business and Human Rights and companies can be further informed by the new UN Guide to Heightened Human Rights Due Diligence for Business in Conflict-Affected Contexts. Committing to the ‘shared space’ of the rule of law, accountable governance, civic freedoms, and human rights. These are both the enablers of civil society and the underpinning of sustainable and profitable business and investment environments. The Chatham House synthesis paper The role of the private sector in protecting civic space sets forth the rationale for companies to defend these vital elements. Supporting peace, justice, and strong institutions both within nations and across the international community as set forth by UN Sustainable Development Goal 16. The SDG 16 Business Framework: Inspiring Transformational Governance shows how companies, as well as national governments and international institutions, can contribute to these building blocks of stability and prosperity. Demonstrating corporate responsibility at the national and geopolitical levels to enhance equity, transparency, and accountability. Multinationals are already challenged to accept minimum corporate taxation within and across jurisdictions, curb excessive executive compensation, endorse mandatory disclosure of environmental and human rights due diligence, and strengthen corporate governance of ESG risks and responsibilities, including with respect to human rights. Diminishing inequality by tackling poverty and ensuring sustainability by arresting the climate crisis. Alongside governments and international institutions, the business community already faces increasing pressure to improve its efforts in these areas. Full Article
change Seven ways Russia’s war on Ukraine has changed the world By www.chathamhouse.org Published On :: Fri, 17 Feb 2023 10:06:57 +0000 Seven ways Russia’s war on Ukraine has changed the world Feature jon.wallace 17 February 2023 Chatham House experts examine the shifts in geopolitical alliances, security, energy, and supply chains and whether these changes are likely to be long-lasting. President Vladimir Putin’s decision to launch a full-scale re-invasion of Ukraine one year ago was a global shock which ‘marked an abrupt end to 30 years of globalization and all the international co-operation that made that possible’ with serious implications for countries around the world, outlined Chatham House director Bronwen Maddox in her inaugural lecture. Not only has the war threatened the stability of Europe but it has also impacted food and energy security globally including in the Middle East and Africa, creating shock waves in a world barely recovering from the COVID-19 pandemic.

There is growing awareness that deforestation and land-use conversion, urbanization, human migration, international commerce, and climate change are having significant impacts on human health, but their impact on increasing infectious disease risks has only become more evident with the coronavirus pandemic. With climate change, and environmental change more generally, disrupting ecologies, and people interacting with wildlife in new ways, it creates the conditions for new diseases to emerge: a better understanding of the health dimensions of environmental change will be critical to managing pandemic risks in future. Our event will examine the relationship between environmental change and disease, how these linkages have manifested in historical outbreaks and in the coronavirus pandemic, and the role of environmental policies in minimizing the risk of future emerging diseases. What can be done to ensure equitable action? What can we learn from our responses to previous pandemics? And will the growing recognition of the diverse risks arising from climate change motivate more climate action? This event will launch the Energy, Environment and Resources (EER) Programme’s Environment and Society Discussion Series. This series aims to provide a platform to promote interdisciplinary knowledge sharing and policy dialogue to mitigate and adapt to the impacts that climate change, biodiversity loss and natural resource depletion are having on people and communities globally, and on geopolitics, security and international development.

change Hydrogen/deuterium exchange memory NMR reveals structural epitopes involved in IgE cross-reactivity of allergenic lipid transfer proteins [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Identification of antibody-binding epitopes is crucial to understand immunological mechanisms. It is of particular interest for allergenic proteins with high cross-reactivity as observed in the lipid transfer protein (LTP) syndrome, which is characterized by severe allergic reactions. Art v 3, a pollen LTP from mugwort, is frequently involved in this cross-reactivity, but no antibody-binding epitopes have been determined so far. To reveal human IgE-binding regions of Art v 3, we produced three murine high-affinity mAbs, which showed 70–90% coverage of the allergenic epitopes from mugwort pollen–allergic patients. As reliable methods to determine structural epitopes with tightly interacting intact antibodies under native conditions are lacking, we developed a straightforward NMR approach termed hydrogen/deuterium exchange memory (HDXMEM). It relies on the slow exchange between the invisible antigen-mAb complex and the free 15N-labeled antigen whose 1H-15N correlations are detected. Due to a memory effect, changes of NH protection during antibody binding are measured. Differences in H/D exchange rates and analyses of mAb reactivity to homologous LTPs revealed three structural epitopes: two partially cross-reactive regions around α-helices 2 and 4 as well as a novel Art v 3–specific epitope at the C terminus. Protein variants with exchanged epitope residues confirmed the antibody-binding sites and revealed strongly reduced IgE reactivity. Using the novel HDXMEM for NMR epitope mapping allowed identification of the first structural epitopes of an allergenic pollen LTP. This knowledge enables improved cross-reactivity prediction for patients suffering from LTP allergy and facilitates design of therapeutics. Full Article
change A natural climate change priority for Africa By www.chathamhouse.org Published On :: Wed, 28 Sep 2022 15:39:21 +0000 A natural climate change priority for Africa Expert comment LJefferson 28 September 2022 Nature-based solutions can protect African nations’ shared natural endowment and meet the needs of their people. Africa’s principal climate change negotiators have long understood the important contribution of ‘nature-based solutions’ (NBS) in delivering land (and sea) based options as part of the goals of the Paris Agreement. Limiting temperature rises to only 1.5°C by 2050 will demand finding innovative ways to protect Africa’s vast natural endowment that also meets the equally acute needs of its people. Nature-based solutions may do both. Decision-makers on the continent and across the world need to understand that ‘business as usual’ cannot be an option given the potential for loss of life, conflict and chaos. The urgency for Africa cannot be overstated. At a Chatham House conference in Libreville, the Gabonese minister for the environment highlighted that if global warming surges by 2.5° or 3°C the impact would be at least 6°C for Africa. Decision-makers on the continent and across the world need to understand that ‘business as usual’ cannot be an option given the potential for loss of life, conflict and chaos. Adaption, mitigation, or both? Although adaptation to climate change has hitherto tended to be the continent’s main concern, there has also been growing recognition of the ways that Africa’s natural environments, from forests and grasslands, to peatlands and coastal and marine ecosystems, all also mitigate its impacts by sequestering carbon. The Congo Basin alone is said to store upwards of 4 per cent of global emissions annually. Arguing that African states should slow the development of their economies in response to a crisis born of the already-industrialized world does not find a responsive audience in a continent hungry for jobs and opportunity. These environments are under increasing pressure. Deforestation is a sad reality, caused mostly by unsustainable and extensive agricultural practices focused on cash crops for export more than food production to feed local populations. And arguing that African states and peoples should slow the development of their economies and infrastructure in response to a crisis born of the already-industrialized world does not find a responsive audience in a continent hungry for jobs and opportunity. Nature-based solutions offer an answer to this conundrum. There is growing evidence that natural habitats both help avoid losses from climate change-related disasters and can drive economic growth. There is thus potential for NBS to tackle both adaptation and mitigation challenges at relatively low cost. NBS – the rocky road from commitment to policy It was logical therefore for Africa and like-minded countries to work to integrate NBS more strongly into the climate change agenda at COP26. The final Glasgow Climate Pact duly emphasized the importance of protecting ecosystems. The Global Forest Finance Pledge signed in the margins was also significant. African focus, with COP 27 in Egypt soon to take place, is now on domestic implementation and delivery of these pledges. The new African Union Climate Change and Resilient Development strategy (2022-2032) sets out many of the challenges and opportunities. Choosing the right development pathway is tough, requiring political will and inclusive governance. Besides the challenge of securing alternative national revenue if a country moves away from fossil-intensive fuels – particularly acute for Africa’s resource-producing states – there is a dizzying array of policy decisions to be taken. African governments need to choose the most appropriate renewable energy sources, secure alternative livelihoods and continue to meet basic needs of the most vulnerable in the context of radical restructuring. Towards African solutions There can be no one-size-fits-all answer to these questions – it is sadly still necessary to underline the enormous geographic, cultural and political diversity of the continent – but African experts have begun to draw together some emerging common themes from work already underway. Maintaining the ‘status quo’ in agricultural practices is no longer an option. Emphasis on sustainable agriculture is urgently needed andthat includes the elaboration of a ‘new deal’ between nature and people. Conservation also needs to be reframed as an economic opportunity, particularly in the elaboration and development of ecosystem services that deliver the true value of Africa’s forests, and that involve, value and reward local communities, respecting their rights and livelihoods. Maintaining the ‘status quo’ in agricultural practices is no longer an option. Emphasis on sustainable agriculture is urgently needed. Regional cooperation is likewise key, including on the management of forest, wildlife and water resources – Africa’s ecosystems do not respect arbitrary political boundaries, and accomplishing the dual feat of protecting cross-border systems at the same time as realizing their economic potential will demand effective collaboration, as well as training, education and communication at all levels. The imperative of finance A further imperative will be securing sufficient developed country financing – whether that be to secure value for net sequestration and effective forest management or for models of context-appropriate ‘smarter’ sustainable rural conservation and ecosystem resilience.

change Modeling PET Data Acquired During Nonsteady Conditions: What If Brain Conditions Change During the Scan? By jnm.snmjournals.org Published On :: 2024-10-24T11:58:49-07:00 Researchers use dynamic PET imaging with target-selective tracer molecules to probe molecular processes. Kinetic models have been developed to describe these processes. The models are typically fitted to the measured PET data with the assumption that the brain is in a steady-state condition for the duration of the scan. The end results are quantitative parameters that characterize the molecular processes. The most common kinetic modeling endpoints are estimates of volume of distribution or the binding potential of a tracer. If the steady state is violated during the scanning period, the standard kinetic models may not apply. To address this issue, time-variant kinetic models have been developed for the characterization of dynamic PET data acquired while significant changes (e.g., short-lived neurotransmitter changes) are occurring in brain processes. These models are intended to extract a transient signal from data. This work in the PET field dates back at least to the 1990s. As interest has grown in imaging nonsteady events, development and refinement of time-variant models has accelerated. These new models, which we classify as belonging to the first, second, or third generation according to their innovation, have used the latest progress in mathematics, image processing, artificial intelligence, and statistics to improve the sensitivity and performance of the earliest practical time-variant models to detect and describe nonsteady phenomena. This review provides a detailed overview of the history of time-variant models in PET. It puts key advancements in the field into historical and scientific context. The sum total of the methods is an ongoing attempt to better understand the nature and implications of neurotransmitter fluctuations and other brief neurochemical phenomena. Full Article

change Solvent accessibility changes in a Na+-dependent C4-dicarboxylate transporter suggest differential substrate effects in a multistep mechanism [Membrane Biology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 The divalent anion sodium symporter (DASS) family (SLC13) plays critical roles in metabolic homeostasis, influencing many processes, including fatty acid synthesis, insulin resistance, and adiposity. DASS transporters catalyze the Na+-driven concentrative uptake of Krebs cycle intermediates and sulfate into cells; disrupting their function can protect against age-related metabolic diseases and can extend lifespan. An inward-facing crystal structure and an outward-facing model of a bacterial DASS family member, VcINDY from Vibrio cholerae, predict an elevator-like transport mechanism involving a large rigid body movement of the substrate-binding site. How substrate binding influences the conformational state of VcINDY is currently unknown. Here, we probe the interaction between substrate binding and protein conformation by monitoring substrate-induced solvent accessibility changes of broadly distributed positions in VcINDY using a site-specific alkylation strategy. Our findings reveal that accessibility to all positions tested is modulated by the presence of substrates, with the majority becoming less accessible in the presence of saturating concentrations of both Na+ and succinate. We also observe separable effects of Na+ and succinate binding at several positions suggesting distinct effects of the two substrates. Furthermore, accessibility changes to a solely succinate-sensitive position suggests that substrate binding is a low-affinity, ordered process. Mapping these accessibility changes onto the structures of VcINDY suggests that Na+ binding drives the transporter into an as-yet-unidentified conformational state, involving rearrangement of the substrate-binding site–associated re-entrant hairpin loops. These findings provide insight into the mechanism of VcINDY, which is currently the only structurally characterized representative of the entire DASS family. Full Article
change Depolarization-dependent Induction of Site-specific Changes in Sialylation on N-linked Glycoproteins in Rat Nerve Terminals [Research] By www.mcponline.org Published On :: 2020-09-01T00:05:24-07:00 Synaptic transmission leading to release of neurotransmitters in the nervous system is a fast and highly dynamic process. Previously, protein interaction and phosphorylation have been thought to be the main regulators of synaptic transmission. Here we show that sialylation of N-linked glycosylation is a novel potential modulator of neurotransmitter release mechanisms by investigating depolarization-dependent changes of formerly sialylated N-linked glycopeptides. We suggest that negatively charged sialic acids can be modulated, similarly to phosphorylation, by the action of sialyltransferases and sialidases thereby changing local structure and function of membrane glycoproteins. We characterized site-specific alteration in sialylation on N-linked glycoproteins in isolated rat nerve terminals after brief depolarization using quantitative sialiomics. We identified 1965 formerly sialylated N-linked glycosites in synaptic proteins and found that the abundances of 430 glycosites changed after 5 s depolarization. We observed changes on essential synaptic proteins such as synaptic vesicle proteins, ion channels and transporters, neurotransmitter receptors and cell adhesion molecules. This study is to our knowledge the first to describe ultra-fast site-specific modulation of the sialiome after brief stimulation of a biological system. Full Article
change Isolation of acetylated and unmodified protein N-terminal peptides by strong cation exchange chromatographic separation of TrypN-digested peptides [Technological Innovation and Resources] By www.mcponline.org Published On :: 2020-11-02T12:35:15-08:00 We developed a simple and rapid method to enrich protein N-terminal peptides, in which the protease TrypN is first employed to generate protein N-terminal peptides without Lys or Arg and internal peptides with two positive charges at their N-termini, and then the N-terminal peptides with or without N-acetylation are separated from the internal peptides by strong cation exchange chromatography according to a retention model based on the charge/orientation of peptides. This approach was applied to 20 μg of human HEK293T cell lysate proteins to profile the N-terminal proteome. On average, 1,550 acetylated and 200 unmodified protein N-terminal peptides were successfully identified in a single LC/MS/MS run with less than 3% contamination with internal peptides, even when we accepted only canonical protein N-termini registered in the Swiss-Prot database. Since this method involves only two steps, protein digestion and chromatographic separation, without the need for tedious chemical reactions, it should be useful for comprehensive profiling of protein N-termini, including proteoforms with neo-N-termini.

change Gender-smart Procurement: Policies for Driving Change By www.chathamhouse.org Published On :: Thu, 14 Dec 2017 15:48:45 +0000 Gender-smart Procurement: Policies for Driving Change Research paper sysadmin 14 December 2017 Governments should use public procurement policy as a strategic lever to accelerate gender-inclusive economic growth through the application of state spending power. — Entrepreneurs Virginia Santy and Melanie Ulle at Women in Kind, a co-working space aimed at small businesses run by women in Denver, US. Photo: Getty Images. Governments need to rethink public procurement policy. They need to use it as a strategic lever to accelerate gender-inclusive economic growth through the application of state spending power, while maintaining rigorous governance standards. Reform of public procurement to make it more gender-inclusive could create a ‘diversity dividend’ through increased job creation and economic growth. Gender-smart procurement policies could also mitigate economic and business risk by rendering supply chains more diverse. In 2014, G20 members agreed to reduce the gender gap in the labour market by 25 per cent by 2025. Procurement policy is one of the most powerful tools governments have to achieve this goal. All G20 members, regardless of the differences in their legal frameworks, can implement measures that will increase the ability of women to benefit from procurement policy. Public procurement accounts for around one-fifth of global gross domestic product (GDP). It is estimated that women entrepreneurs supply only 1 per cent of this market. Women’s businesses face considerable barriers to accessing procurement tenders and winning procurement contracts. The inadequate design of many procurement processes prevents more inclusive gender outcomes for citizens. Governments should redefine procurement policies to make explicit the requirement that increasing women’s workforce participation, through greater use of female suppliers, is a key objective when selecting bids for procurement contracts. Through the use of policy and spending levers, governments can play four primary roles in encouraging procurement from enterprises owned by women, or from businesses committed to promoting female labour participation. These roles are: - To direct reforms of government procurement – reviewing procurement policies and practices to ensure sustainable and inclusive procurement; - To reduce barriers to women’s participation in the economy – creating the support mechanisms to ensure an environment in which businesses owned by women can flourish; - To help scale up gender-smart procurement in the private sector – expanding government’s role in encouraging private companies to spend more of their procurement budgets with women’s businesses; and - To encourage increased transparency on the issues – creating and sharing procurement databases and lessons learned, especially at the regional level. Companies can also benefit from having more diverse supply chains and volunteering for accreditation schemes. They can start conversations with government about national regulation that encourages diversity in procurement, leading by example. The G20 should set measurable and time-bound targets in the area of gender-smart procurement, to build on the momentum of UN reforms and incorporate good practice in supply chain management.

change Afonso Dhlakama’s Death Changes the Calculation for Peace Prospects in Mozambique By www.chathamhouse.org Published On :: Fri, 04 May 2018 13:30:19 +0000 Afonso Dhlakama’s Death Changes the Calculation for Peace Prospects in Mozambique Expert comment sysadmin 4 May 2018 If politicians continue to act in good faith, the death of the opposition leader may be a significant opportunity to finally draw a line under Mozambique’s long war. — Afonso Dhlakama addresses a crowd of supporters at a campaign rally in 2014. Photo: Getty Images. The unexpected death of opposition and ex-rebel leader Afonso Dhlakama on 3 May is a game changer for Mozambique’s politics and an almost-completed peace process. The 65-year old Dhlakama, who died of a heart attack, had led Renamo for 38 years and had totally dominated his party. Dhlakama regularly boasted that he was Mozambique’s ‘father of democracy’, despite not allowing competition within his own party, and he leaves a legacy of more than 30 years of struggle, through both armed action and peaceful politics.A long warOriginally Renamo had been a tool for the white minority regimes of Rhodesia and apartheid South Africa to challenge the socialist Frelimo political party that took power in Mozambique in 1975. But under Dhlakama’s command, by the late 1980s Renamo had become increasingly independent and rooted in Mozambique. After Renamo’s long war with Frelimo ground to a hurting stalemate, a transition led to Mozambique’s first multiparty elections in 1994, and the creation of a new joint army. A ‘pay and scatter’ programme successfully dispersed and reintegrated many thousands of ex-combatants.But early post-election gains did not translate to lasting peace. Disarmament was a time-limited, technical process, and devoted declining resources and attention to clusters of ex-combatants that failed to disperse. In addition, Dhlakama was allowed to maintain an armed militia under the guise of a presidential guard.Mounting economic inequality, notably in opposition strongholds such as central Mozambique, saw Renamo made political gains and Dhlakama nearly won the 1999 presidential elections. (Some believe he did.) The result focused Frelimo’s attention on the threat that Renamo posed and, ultimately, a strategy of pursuing total Frelimo domination across the country, culminating in a crushing Frelimo victory at the 2009 elections.This humiliated and marginalized former Renamo rebels, resulting in Dhlakama ordering their return to targeted armed violence in 2013. Frelimo’s new leader, President Filipe Nyusi, took power in 2015 and sought direct dialogue with Dhlakama. Five rounds of internationally mediated peace talks took place from July to December. Finally, in late December 2016, Dhlakama announced a unilateral truce, which was extended twice and subsequently made indefinite.New peace talks also started and, in August 2017 and February 2018, President Nyusi and Dhlakama showed the courage to meet in person, near Renamo’s base in central Mozambique, to build up mutual trust and discuss the details of the emerging peace deal – including the demobilization or integration into government security forces for Renamo’s now mostly middle-aged gunmen.Dhlakama the ‘Big Man’Dhlakama’s sudden death has fundamentally changed the negotiation dynamics. He never allowed for any serious succession planning, and ensured all key decisions were his and his alone. Renamo had already decided that he would be its presidential candidate for the 2019 national elections.His party is significantly weakened by his death and unlikely able to fully recover – but needs to try and reach consensus quickly on a successor, as it will also compete in municipal elections in October and was expecting significant gains. There will be a number of contenders to succeed him including from the parliamentary wing, led by his niece Ivone Soares, its secretary general, Manuel Bissopo, and a few others.But Renamo’s key leverage for now remains some 1,000 middle-aged gunmen in central Mozambique who have been stoically loyal to Dhlakama since the 1980s and who have little respect for the younger generation of professional politicians based in Maputo. Some may be bought off by government offers, others integrated into localised organized crime groups and others into internal Renamo sectarianism. The risk of fragmentation is real.Renamo’s weakness could also embolden Frelimo hardliners to seek a return to unilateral domination of Mozambique’s political landscape, and to undermine the peace process. That would be a serious tactical mistake by Frelimo, as a lasting deal is close and the death of Dhlakama could actually assist in making this settlement lasting. Dhlakama was quixotic and prone to changing his mind, often influenced by the last person he spoke to – his death potentially introduces greater predictability in negotiations and in any post-deal implementation.President Nyusi is clearly aware of this as he hailed on state television TVM that Dhlakama was ‘a citizen who has always worked for Mozambique’ and said he was distraught at the news of his death. He stated, ‘I hope that we as Mozambicans can continue to do everything so things do not go down.’ He also addressed Renamo’s support base by saying that ‘[Dhlakama] did everything so that there would be peace. The last time he spoke to me, he said he was not going to miss out anything in peace negotiations.’Renamo’s gunmen are fatigued and want to retire with dignity but are vulnerable to manipulation and political miscalculation by Mozambican’s positioning politicians. International partners and investors can engage, by emphasizing that sustainable peace is the only pathway to poverty reduction and inclusive economic development.This includes assisting development and reconciliation projects in areas impacted by the renewed conflict since 2013. Long-term investment for development in Renamo’s key constituencies could help avoid fragmentation at a critical time – faith groups and NGOs may also have a key role to play.If Mozambique’s politicians continue to act in good faith, the death of Dhlakama may constitute a significant opportunity to finally draw a line under Mozambique’s long war.

change Russia’s invasion of Ukraine: How it changed the world By www.chathamhouse.org Published On :: Wed, 01 Feb 2023 15:52:13 +0000 Russia’s invasion of Ukraine: How it changed the world 21 February 2023 — 6:00PM TO 7:00PM Anonymous (not verified) 1 February 2023 Chatham House and Online Chatham House experts examine how the world has changed since 24 February 2022. Russia’s invasion of Ukraine prompted serious soul-searching about European security, what it means to be European and the futures of the two principal protagonists. However, practical questions have developed throughout the war in surprising ways. Chatham House is producing a multi-author feature reflecting on seven things Russia’s war has changed in the world. The article assesses the impact of the war one year on, the long-term changes this has catalyzed and unpacks why these changes are significant for the future of international affairs. This event examines key themes with the research directors who authored the piece. Alliances, national resiliency for both Ukraine and Russia and sanctions are examined including the following questions: How did the war change Ukraine? What alliances have been forged over the past year? How long can ‘fortress Russia’ weather the storm and what has it revealed about Russia’s integration into the international system? What have countries done to mitigate the impact on supply chains and markets? Who, for example, has been most affected by the grain crisis? What have we learnt about Vladimir Putin and Volodymyr Zelensky that we didn’t know before 24 February 2022? As with all members events, questions from the audience drive the conversation.

change Russian imperial mindset must change for real victory By www.chathamhouse.org Published On :: Thu, 08 Dec 2022 09:47:14 +0000 Russian imperial mindset must change for real victory Expert comment NCapeling 8 December 2022 The attitude of Russia’s elite – and wider population – to the states which used to constitute the USSR needs to change in order to solve the Russia challenge. Although the reverberations of Russia’s invasion of Ukraine clearly stretch around the globe, the strongest shocks are – and will continue to be – felt by those countries Moscow used to directly rule. These countries struggle to shrug off a Soviet legacy as, to varying degrees – linguistically, technologically, culturally, and politically – they bear psychological and physical scars of Russia’s colonial past and its present mentality. It does not help that these countries lack an appropriate collective descriptor. Over the years there has been ‘Newly Independent States’ – hardly appropriate after 31 years – the now-defunct ‘Commonwealth of Independent States’, the ‘post-Soviet space’ and ‘Former Soviet Union’ which both reference the past, and simply ‘Eurasia’ which is hardly appropriate for either Ukraine or Turkmenistan. Some of these former ‘colonies’ are as badly governed and as sinister – albeit not as lethal beyond their borders – as Russia itself. Others, most notably the Baltic states, are modern, liberal, affluent societies, but Moscow’s shadow still looms. There is a strong mindset in most of Russia’s citizens that, because that it used to rule these other countries, it either still has privileged rights over them or they are not real countries at all – but instead historical aberrations to be extinguished. What is past is gone As historian Timothy Snyder has noted, whatever the wrongs of Putin’s ‘history-based’ assertions about the ‘return of historic lands’, all historical claims are bunkum anyway. If the past brings validity, almost no land border on earth would be beyond dispute. It is agreements which count, and Russia signed away the other successor states in 1991. There is a strong mindset in most of Russia’s citizens that, because that it used to rule these other countries, it either still has privileged rights over them or they are not real countries at all The Russia and Eurasia programme at Chatham House has, for the last 31 years, always taken as a starting position that these countries are as sovereign as any other. This of course this means they can choose to be in Russia’s embrace if they wish. But none do because Russia is insufficiently attractive. Some have better relationships with Moscow than others – mainly the more autocratic ones – but no former slave goes back to their master willingly. At the recent Chatham House conference Russia’s war: How will it shape the region’s future? (note the avoidance of a specific descriptor), the overwhelming consensus was that Russia must lose, that Ukraine must be reconstructed and planning for that must start now, and that the regional economy is convulsing. But another key view was that, in Russia, rent seeking and buying loyalty are likely to lead to the separation of the Russian people and the regime, especially as the population ages and young men being sent to die at the front. Putin may still be popular in some places in Russia, but not in others – although popularity can rise and fall fast in Russia. However, few at the conference foresaw the disintegration of Russia any time soon. With continued skill, determination, and more weaponry, Ukraine may well vanquish Russia on the battlefield, and this remains a necessary pre-requisite for European security. But even a Ukraine victory will not erase malign intent. Getting Russians to look upon their neighbours as equals requires widescale self-reassessment in a post-Putin Russia The Russian imperial itch is so deeply embedded, it must be excised not just from Russian capability but from the intention and mindset of elites and in the popular imagination. That is hard to achieve when so many believe in it as fervently as a religion – even the Russian Orthodox Church invokes a messianism in Russia’s imperial ‘rights’. The wider region is suffering Getting Russians to look upon their neighbours as equals requires widescale self-reassessment in a post-Putin Russia. But, for now, the wider region will surely be looking to simply neuter Russia’s destructive capacities. Full Article
