z A Sandwich, A Wallet, and Elizabeth Taylor's Cousin By www.43folders.com Published On :: Thu, 04 Nov 2010 22:31:36 +0000 Being a Parable for the Edification of Independents Seeking Independence THE PARABLE THE OSTENSIBLE CUSTOMER enters a deli and saunters up to the counter. The deli is tended by its rakishly handsome owner, THE SANDWICH GUY. "Hi," says The Sandwich Guy. "What looks good to you today?" "Slow down," says The Ostensible Customer, as THE LUNCH RUSH starts trickling in. "Lots of delis want my business, so, first I need to really understand what you can do for me." "Well," says The Sandwich Guy, "I guess I can try to do what I do for everybody here and make you a customized version of any of the 15 awesome sandwiches you see on my menu. What're you hungry for?" "Easy, easy, Ricky Roma! Before I make any decisions here I'm going to need to know a lot more about my options. Why are you so obsessed with 'what I want?'" "Okay, sorry," says The Sandwich Guy, uneasily eyeing the growing queue of The Lunch Rush now piling up behind The Ostensible Customer. "What else can I do to help here?" "That's better," says The Ostensible Customer. "Let's start by sitting down for a couple hours and going over all the ingredients you have back there." The Sandwich Guy laughs congenially and hands The Ostensible Customer a menu. "Friend, I can make you whatever you want, but, if it helps, the 15 sandwiches listed here show all the ingredients--right there between the name and the price..." "Whoa, whoa, whoa! The price?!? Already you're reaching for my wallet? Jeez, I barely just arrived." The Lunch Rush is getting restless and grumbling audibly. "Well. You know. I do sell sandwiches for a living," says The Sandwich Guy. "Did you have a certain budget in mind for your lunch?" "Oh, God, no. I'm nowhere near that point yet. I still need to learn a lot more about how you work, and so, obviously, I have no idea what I want to pay. Obviously." "Okay," says The Sandwich Guy, "but...I can't do much for you here without knowing either what you want to eat or how much money you want to spend. You get that, right?" The Ostensible Customer is miffed. "Listen, here. What I 'get,' so-called Sandwich Guy, is that you're not going to rush me into some tricky lifetime sandwich commitment until I understand precisely who I'm working with. And, so far, I do not like what I see. Still. I intend to find out more. So, meet me in Canada tomorrow to talk about this for an hour." The Lunch Rush begins waving their wallets as they lob their completed order forms at The Sandwich Guy's face. "Sorry," says The Sandwich Guy. "I can't do that. How about I just make you a Reuben. It's really good, it's our most popular sandwich, and it only costs eight bucks." "WHAT! EIGHT DOLLARS! 'Dollars' with a 'd?' That's way too much!" "I thought you didn't have a budget," says The Sandwich Guy. "Well, I don't. And, besides, I don't really 'need' a sandwich at all. Now, kindly fly to Canada." "That's not going to happen, sir." "Also," says The Ostensible Customer, "if I do decide to get a sandwich from you--and it's looking increasingly less likely that I will--I'll absolutely expect your deeply discounted price to reflect the fact that I'm not particularly hungry right now." The Lunch Rush begins lighting torches and chanting a guttural chant, not unlike the haunting overtone singing of Tuvan herdsmen. "Look," sighs The Sandwich Guy, "it sounds like you need a little more time. Here's a free Coke and a complimentary bowl of pickles. Please have a seat, take all the time you need, then just come on up whenever you're ready to order, okay?" "‘READY?!?’ TO...‘ORDER?!?’ Are you out of your mind?" "Mmmm...apparently." Presently, The Ostensible Customer turns beet-red. "This is an outrage! I can't even imagine how you stay in business when you treat your customers like this." The Lunch Rush grows silent as The Sandwich Guy slowly leans over the counter and smiles--his nose one slice of corned beef from The Ostensible Customer's nose. "Sir. First off: you aren't my customer yet. Right now, you're just some dude holding a bowl of free pickles." "Buh?" fumbled The Ostensible Customer. "And, second, the way I 'stay in business' is by making great sandwiches and having as few conversations like the one we're having as possible," The Sandwich Guy coos. "Because, the truth is, my real customers are actually all those nice people standing behind you. They're the people who buy my sandwiches with real money over and over again. I really like them, and so I give them almost all of my attention." The Sandwich Guy waves at The Lunch Rush. The Lunch Rush waves back. The Ostensible Customer looks stunned. "Sir," says The Sandwich Guy "enjoy your Coke and your pickles with my compliments. But, please step aside. Because right now, there's a whole bunch of hungry people trying to buy sandwiches that won't require me flying to Canada. Next, please!" The Lunch Rush roars approval. The Ostensible Customer is still stunned. Which is unfortunate. Because, several men from the back of the line spontaneously rush forward to drag The Ostensible Customer, screaming and grasping, onto the busy sidewalk outside, where they proceed to devour his flesh like those street urchins who eat Elizabeth Taylor's cousin in Suddenly, Last Summer. Meanwhile, The Sandwich Guy goes back to making sandwiches. And, The Lunch Rush goes back to eating them. THE MORAL(S)? The Sandwich Guy can't do much for you until you're hungry enough to really want a sandwich. Once you're hungry enough, you still have to pay money for the sandwich. This won't not come up. Few people become "a good customer" without understanding both 1 and 2. Few companies become "a smart business" without understanding 1, 2, and 3. Basing his business on an understanding of 1, 2, 3, 4, and 5 doesn't make The Sandwich Guy a dick; it makes him a smart business. If you vacation with Elizabeth Taylor? Seriously. Avoid provoking the cannibalistic rent boys. THE HOPE Me? I just very much hope it takes you far less than 15 years to see and accept these sorts of things. Both as a customer and as a business. Guys, avoid working for anyone who's not hungry enough to compensate you for your sandwich. It literally doesn't pay.

z China’s zero-COVID cannot continue, reopening is needed By www.chathamhouse.org Published On :: Thu, 01 Dec 2022 11:16:46 +0000 China’s zero-COVID cannot continue, reopening is needed Expert comment NCapeling 1 December 2022 Unsure of how to loosen rules, local officials have doubled down on severe restrictions behind so much economic damage. Reopening will quell public anger. When President Xi Jinping was seen unmasked at the G20 summit in Indonesia, he maintained a largely positive tone with President Joe Biden and other world leaders. This left an impression that China was on the verge of withdrawing its zero-COVID strategy. A set of loosening policy measures introduced by Beijing seemed to further suggest that China was on track to reopen. As outlined in the 20th party congress, Xi wants to forge a pathway towards economic modernization and this means building economic resilience and a further increase in household incomes. However, a series of displays of public defiance against the government’s zero-COVID policy has left the rest of the world perplexed. Some loosening of restrictions announced on 11 November by the central government, with the number of new cases still rising rapidly, left the provincial governments in confusion as to which direction to turn. Absolute political loyalty The persistent slogan of ‘zero-COVID’ was in stark contrast to the slackening of restrictions. Local officials decided to double down on stringent COVID measures as a way of displaying absolute political loyalty to the top, which inevitably caused daily agonies among large parts of the Chinese population. The strategy has intensified economic pressures, exacerbated rising levels of youth unemployment, and tested the patience of the entire country This decision-making process sheds some light on the way the Chinese bureaucracy approaches crises at a time when the party leadership is tightening political control. Lower-level officials avoided making important decisions and instead decided to wait for instructions from the top. As the rules were unclear, they implemented policies according to past precedents, in this case zero-COVID, which had worked relatively well for China in 2020 and 2021. For decades, local governments have been major political actors in China and have known what works best under local conditions. But with tighter regulation being exercised by lower-level bureaucrats and civil servants, there is less opportunity for the input of local knowledge, increasing the risk of ineffective policies being implemented. Away from Beijing, those not employed by the state have been hit particularly hard by zero-COVID measures. The strategy has intensified economic pressures, exacerbated rising levels of youth unemployment, and tested the patience of the entire country. It is difficult to see how China’s economy can crank up again until the country reduces its internal restrictions and reconnects with the world Billions of Chinese people want to have their life return to normal without the fear of having the wrong colour – yellow or red – on their COVID health QR code or endless mandatory testing. Only a green code shows that a person is healthy and able to move around freely. Economy is suffering China is still balancing its twin aims of containing the spread of COVID and re-engineering its economy along similar lines to the rest of the world. It is difficult to see how China’s economy can crank up again until the country reduces its internal restrictions and reconnects with the world. Full Article
z Analysis of {beta}-lactone formation by clinically observed carbapenemases informs on a novel antibiotic resistance mechanism [Enzymology] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 An important mechanism of resistance to β-lactam antibiotics is via their β-lactamase–catalyzed hydrolysis. Recent work has shown that, in addition to the established hydrolysis products, the reaction of the class D nucleophilic serine β-lactamases (SBLs) with carbapenems also produces β-lactones. We report studies on the factors determining β-lactone formation by class D SBLs. We show that variations in hydrophobic residues at the active site of class D SBLs (i.e. Trp105, Val120, and Leu158, using OXA-48 numbering) impact on the relative levels of β-lactones and hydrolysis products formed. Some variants, i.e. the OXA-48 V120L and OXA-23 V128L variants, catalyze increased β-lactone formation compared with the WT enzymes. The results of kinetic and product studies reveal that variations of residues other than those directly involved in catalysis, including those arising from clinically observed mutations, can alter the reaction outcome of class D SBL catalysis. NMR studies show that some class D SBL variants catalyze formation of β-lactones from all clinically relevant carbapenems regardless of the presence or absence of a 1β-methyl substituent. Analysis of reported crystal structures for carbapenem-derived acyl-enzyme complexes reveals preferred conformations for hydrolysis and β-lactone formation. The observation of increased β-lactone formation by class D SBL variants, including the clinically observed carbapenemase OXA-48 V120L, supports the proposal that class D SBL-catalyzed rearrangement of β-lactams to β-lactones is important as a resistance mechanism.

z Mutation of an atypical oxirane oxyanion hole improves regioselectivity of the {alpha}/{beta}-fold epoxide hydrolase Alp1U [Enzymology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Epoxide hydrolases (EHs) have been characterized and engineered as biocatalysts that convert epoxides to valuable chiral vicinal diol precursors of drugs and bioactive compounds. Nonetheless, the regioselectivity control of the epoxide ring opening by EHs remains challenging. Alp1U is an α/β-fold EH that exhibits poor regioselectivity in the epoxide hydrolysis of fluostatin C (compound 1) and produces a pair of stereoisomers. Herein, we established the absolute configuration of the two stereoisomeric products and determined the crystal structure of Alp1U. A Trp-186/Trp-187/Tyr-247 oxirane oxygen hole was identified in Alp1U that replaced the canonical Tyr/Tyr pair in α/β-EHs. Mutation of residues in the atypical oxirane oxygen hole of Alp1U improved the regioselectivity for epoxide hydrolysis on 1. The single site Y247F mutation led to highly regioselective (98%) attack at C-3 of 1, whereas the double mutation W187F/Y247F resulted in regioselective (94%) nucleophilic attack at C-2. Furthermore, single-crystal X-ray structures of the two regioselective Alp1U variants in complex with 1 were determined. These findings allowed insights into the reaction details of Alp1U and provided a new approach for engineering regioselective epoxide hydrolases. Full Article
z Structure, mechanism, and regulation of mitochondrial DNA transcription initiation [Enzymology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Mitochondria are specialized compartments that produce requisite ATP to fuel cellular functions and serve as centers of metabolite processing, cellular signaling, and apoptosis. To accomplish these roles, mitochondria rely on the genetic information in their small genome (mitochondrial DNA) and the nucleus. A growing appreciation for mitochondria's role in a myriad of human diseases, including inherited genetic disorders, degenerative diseases, inflammation, and cancer, has fueled the study of biochemical mechanisms that control mitochondrial function. The mitochondrial transcriptional machinery is different from nuclear machinery. The in vitro re-constituted transcriptional complexes of Saccharomyces cerevisiae (yeast) and humans, aided with high-resolution structures and biochemical characterizations, have provided a deeper understanding of the mechanism and regulation of mitochondrial DNA transcription. In this review, we will discuss recent advances in the structure and mechanism of mitochondrial transcription initiation. We will follow up with recent discoveries and formative findings regarding the regulatory events that control mitochondrial DNA transcription, focusing on those involved in cross-talk between the mitochondria and nucleus.

z In conversation with Valerii Zaluzhnyi, Ukrainian Ambassador to the UK By www.chathamhouse.org Published On :: Mon, 16 Sep 2024 19:47:13 +0000 In conversation with Valerii Zaluzhnyi, Ukrainian Ambassador to the UK 17 October 2024 — 10:00AM TO 11:00AM Anonymous (not verified) 16 September 2024 Chatham House and Online The former Commander-in-Chief of the Armed Forces of Ukraine offers insight into the evolution of Russia’s war against his country, and what to expect next. More than two and a half years since Russia launched its full-scale invasion, Ukraine has consistently adapted to Moscow’s advances by implementing new strategies.Ukraine’s recent incursion into Russia’s Kursk region demonstrated operational tactical ingenuity, surprising both Russia and Ukraine’s Western supporters. Success against the Russian Black Sea Fleet has already showcased how Ukraine can skilfully beat back Russian aggression. And increasing numbers of targeted strikes on Russian supply depots and airfields are disrupting Russian operations behind the front lines.Critical Western supplies continue to resource Ukraine’s military. But questions linger over the quantity and sustainability of these supplies. Kyiv will be watching the US presidential election in November as its biggest backer goes to the polls with the possibility of an outcome that could seriously affect the war. Meanwhile, Russian forces continue to edge forward in Donbas, despite heavy casualties, and strike at Ukrainian towns and cities from the air, demonstrating that President Putin has no intention of relinquishing the fight.Amid these complexities, Ambassador Zaluzhnyi will discuss how the war is changing both sides, advances on the battlefield, and what dangers lie ahead for Ukraine in the coming months. Other key questions include:What kind of enemy is Russia today and how to secure its strategic defeat in Ukraine;How have new strategies, such as the recent incursion into the Kursk region, affected the state of play on the battlefield?What technologies and armaments does Ukraine need from its Western allies in both the short and long term?Individual membership provides you with the complete Chatham House experience, connecting you with a unique global policy community.

z [4Fe-4S] cluster trafficking mediated by Arabidopsis mitochondrial ISCA and NFU proteins [Enzymology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Numerous iron-sulfur (Fe-S) proteins with diverse functions are present in the matrix and respiratory chain complexes of mitochondria. Although [4Fe-4S] clusters are the most common type of Fe-S cluster in mitochondria, the molecular mechanism of [4Fe-4S] cluster assembly and insertion into target proteins by the mitochondrial iron-sulfur cluster (ISC) maturation system is not well-understood. Here we report a detailed characterization of two late-acting Fe-S cluster-carrier proteins from Arabidopsis thaliana, NFU4 and NFU5. Yeast two-hybrid and bimolecular fluorescence complementation studies demonstrated interaction of both the NFU4 and NFU5 proteins with the ISCA class of Fe-S carrier proteins. Recombinant NFU4 and NFU5 were purified as apo-proteins after expression in Escherichia coli. In vitro Fe-S cluster reconstitution led to the insertion of one [4Fe-4S]2+ cluster per homodimer as determined by UV-visible absorption/CD, resonance Raman and EPR spectroscopy, and analytical studies. Cluster transfer reactions, monitored by UV-visible absorption and CD spectroscopy, showed that a [4Fe-4S]2+ cluster-bound ISCA1a/2 heterodimer is effective in transferring [4Fe-4S]2+ clusters to both NFU4 and NFU5 with negligible back reaction. In addition, [4Fe-4S]2+ cluster-bound ISCA1a/2, NFU4, and NFU5 were all found to be effective [4Fe-4S]2+ cluster donors for maturation of the mitochondrial apo-aconitase 2 as assessed by enzyme activity measurements. The results demonstrate rapid, unidirectional, and quantitative [4Fe-4S]2+ cluster transfer from ISCA1a/2 to NFU4 or NFU5 that further delineates their respective positions in the plant ISC machinery and their contributions to the maturation of client [4Fe-4S] cluster-containing proteins.

z Unusual zwitterionic catalytic site of SARS-CoV-2 main protease revealed by neutron crystallography [Enzymology] By www.jbc.org Published On :: 2020-12-11T00:06:21-08:00 The main protease (3CL Mpro) from SARS–CoV-2, the etiological agent of COVID-19, is an essential enzyme for viral replication. 3CL Mpro possesses an unusual catalytic dyad composed of Cys145 and His41 residues. A critical question in the field has been what the protonation states of the ionizable residues in the substrate-binding active-site cavity are; resolving this point would help understand the catalytic details of the enzyme and inform rational drug development against this pernicious virus. Here, we present the room-temperature neutron structure of 3CL Mpro, which allowed direct determination of hydrogen atom positions and, hence, protonation states in the protease. We observe that the catalytic site natively adopts a zwitterionic reactive form in which Cys145 is in the negatively charged thiolate state and His41 is doubly protonated and positively charged, instead of the neutral unreactive state usually envisaged. The neutron structure also identified the protonation states, and thus electrical charges, of all other amino acid residues and revealed intricate hydrogen-bonding networks in the active-site cavity and at the dimer interface. The fine atomic details present in this structure were made possible by the unique scattering properties of the neutron, which is an ideal probe for locating hydrogen positions and experimentally determining protonation states at near-physiological temperature. Our observations provide critical information for structure-assisted and computational drug design, allowing precise tailoring of inhibitors to the enzyme's electrostatic environment. Full Article
z Allosteric activation of proto-oncogene kinase Src by GPCR-beta-arrestin complexes [Enzymology] By www.jbc.org Published On :: 2020-12-04T00:06:06-08:00 G protein–coupled receptors (GPCRs) initiate signaling cascades via G-proteins and beta-arrestins (βarr). βarr-dependent actions begin with recruitment of βarr to the phosphorylated receptor tail and are followed by engagement with the receptor core. βarrs are known to act as adaptor proteins binding receptors and various effectors, but it is unclear whether in addition to the scaffolding role βarrs can allosterically activate their downstream targets. Here we demonstrate the direct allosteric activation of proto-oncogene kinase Src by GPCR–βarr complexes in vitro and establish the conformational basis of the activation. Whereas free βarr1 had no effect on Src activity, βarr1 in complex with M2 muscarinic or β2-adrenergic receptors reconstituted in lipid nanodiscs activate Src by reducing the lag phase in Src autophosphorylation. Interestingly, receptor–βarr1 complexes formed with a βarr1 mutant, in which the finger-loop, required to interact with the receptor core, has been deleted, fully retain the ability to activate Src. Similarly, βarr1 in complex with only a phosphorylated C-terminal tail of the vasopressin 2 receptor activates Src as efficiently as GPCR–βarr complexes. In contrast, βarr1 and chimeric M2 receptor with nonphosphorylated C-terminal tail failed to activate Src. Taken together, these data demonstrate that the phosphorylated GPCR tail interaction with βarr1 is necessary and sufficient to empower it to allosterically activate Src. Our findings may have implications for understanding more broadly the mechanisms of allosteric activation of downstream targets by βarrs. Full Article
z Webinar: Is It All Over For Globalization? By www.chathamhouse.org Published On :: Wed, 08 Apr 2020 12:55:01 +0000 Webinar: Is It All Over For Globalization? 15 April 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 8 April 2020 The coronavirus pandemic has led many to predict the end of globalization. Confronted with unprecedented social and economic challenges, countries are prioritizing their own citizens. Now, more than ever, international cooperation is necessary but, amidst the rise of nationalist-populist governments, global partnerships are absent or faltering. And as economies grind to a halt, so does international commerce — particularly in trade-dependent Asia, a region whose rise drove the period of ‘hyper-globalization’ which preceded the global financial crisis. Yet there are other possible futures too. The level of scientific collaboration and information-sharing now underway in search of a vaccine is unprecedented, and after a hesitant beginning the major powers have woken up to the importance of concerted economic stimuli. The virus may in some ways have the paradoxical result of bringing countries together, not driving them apart. Rather than causing its demise, it could help begin a new period in which globalization is not as deep, but at least is better managed and more equitable? Could this be the catalyst for a new coming together at home and abroad? In this webinar, speakers debate what impact the COVID-19 pandemic will have on the future of globalization, both in Asia and around the world. Full Article
z Why burning biomass is not zero-carbon By www.chathamhouse.org Published On :: Mon, 17 Oct 2022 14:02:50 +0000 Why burning biomass is not zero-carbon Explainer Video NCapeling 17 October 2022 Short animation explaining why burning biomass produces more carbon dioxide per unit of energy generated than almost all fossil fuels. The climate emergency requires countries to transition away from fossil fuels, but it is important to be careful about the alternative energy sources chosen. In particular, concern is growing over the use of biomass for energy, which is generated when wood or other plant material is burnt to generate heat and electricity. Many governments treat biomass energy as zero-carbon at the point of combustion, and subsidize it in the same way as renewables such as solar or wind, resulting in a large increase in the use of biomass for energy in the UK and the European Union (EU) over the past 15 years. The treatment of biomass as zero-carbon in policy frameworks rests on the argument that biomass emissions will be reabsorbed by forest growth, particularly from trees planted to replace those cut down to burn. But growing trees to maturity takes many years and, depending on the feedstock used, biomass burning increases global warming for decades to centuries. This is called the ‘carbon payback period’ – the time it takes for carbon dioxide levels to return to what they would have been if biomass had not been used. New research from Chatham House and the Woodwell Climate Research Center calculated the real climate impact of burning US wood pellets in the UK and EU. In 2019, according to this analysis, US-sourced pellets burned for energy in the UK were responsible for between 13 million and 16 million tonnes of carbon dioxide, equivalent to the annual greenhouse gas emissions from 6-7 million passenger vehicles. But because biomass is treated as zero-carbon, almost none of these emissions were included in the UK’s national greenhouse gas reports. And the removal of forest carbon from US forests is not included accurately in US reports, either. Full Article
z World economy is fracturing, not deglobalizing By www.chathamhouse.org Published On :: Wed, 08 Feb 2023 13:15:11 +0000 World economy is fracturing, not deglobalizing Expert comment LJefferson 8 February 2023 Geopolitics are creating a more uncertain economic environment as the global economy splinters into competing blocs. There is now broad agreement among economists and commentators that the world has reached peak globalization, but there is little consensus about what comes next. One view is that we are entering a period of ‘deglobalization’, in which global trade volumes decline and cross-border capital flows recede. An alternative and more likely outcome is that the global economy starts to splinter into competing blocs. This would result in an altogether more volatile macroeconomic and market environment which would pose a formidable challenge to some countries and companies operating in vulnerable sectors. But this process needn’t involve any significant shrinkage of international flows of goods, services and capital, nor a broad reversal of other gains of globalization. Whereas the period of globalization was driven by governments and companies working in unison, fracturing is being driven by governments alone. This most recent era of globalization was underpinned by a belief that economic integration would lead to China and the former Eastern Bloc countries becoming what former World Bank Chief Robert Zoellick termed ‘responsible stakeholders’ within the global system. But China has instead emerged as a strategic rival to the US. This strategic rivalry is already forcing others to pick sides as the world splinters into two blocs: one that aligns primarily with the US and another that aligns primarily with China. Increasingly, policy choices within these blocs will be shaped by geopolitical considerations. This process can be thought of as ‘global fracturing’. Whereas the period of globalization was driven by governments and companies working in unison, fracturing is being driven by governments alone. The effects of fracturing Viewed this way, ‘deglobalization’ is by no means inevitable. There are few compelling geopolitical reasons why the US or Europe should stop importing the majority of consumer goods from China. Roll the clock forward ten years and it is likely that the West will still be buying toys and furniture from China. Instead, fracturing between the blocs will take place along fault lines that are geopolitically important. In some aspects, the effects of fracturing will be profound. But in other areas, warnings of a seismic reordering of the global economy and financial system will prove wide of the mark. For example, the politically-driven nature of fracturing will have a significant impact on the operating environment for US and European firms in those sectors that are most exposed to restrictions on trade, such as technology and pharmaceuticals. And all firms and investors will be operating in a different environment in which geopolitical considerations play a greater role in decisions over the allocation of resources. In cases where production does shift location, it is likely to be to other low-cost centres that align more clearly with the US. There will be no great ‘reshoring’ of manufacturing jobs. But where production is moved to alternative locations, this is likely to only involve the manufacture of goods that are deemed to be strategically significant. This may include those with substantial technological and/or intellectual property components: think iPhones, pharmaceuticals, or high-end engineering products. What’s more, in cases where production does shift location, it is likely to be to other low-cost centres that align more clearly with the US. There will be no great ‘reshoring’ of manufacturing jobs. Within this process, trade linkages will be reordered, rather than severed. This will result in trade’s share of global GDP flatlining in the coming years, rather than shrinking outright, as is being forecast under many attempts to quantify deglobalization’s potential impact. Finances of global fracturing There will be a substantial financial component to global fracturing, but once again the implications are likely to be more nuanced than the current debate suggests. Cross-border financial links are likely to grow more slowly, and the overall stock of cross-border claims will plateau relative to global GDP. But whereas the first era of globalization in the 1870s was followed by a broad retreat in global capital flows during the interwar years, the same is unlikely to happen today. Beijing will increasingly push its partners to settle trade in renminbi but this is unlikely to seriously challenge the dollar’s position. Similarly, while financial fracturing will fuel growing speculation about the dollar’s role as the world’s reserve currency, reports of its impending demise are exaggerated. Beijing will increasingly push its partners to settle trade in renminbi but three factors suggest that this is unlikely to seriously challenge the dollar’s position. First, while trade between China and its partners is growing, it still accounts for only six per cent of global trade. Most trade still happens between US-aligned countries, and will continue to be denominated in US dollars (see chart). Second, China runs a large current account surplus, which will make it harder for the renminbi to supplant the dollar. High demand for reserve assets means that reserve countries tend to run current account deficits. — Share of global goods and services trade (%) Source: Capital Economics Finally, the dollar still has several things working in its favour. For a currency to be widely used as an international medium of exchange, it must be readily and cheaply available around the world. In turn, that depends on foreigners being willing to hold it in large volumes: in other words, it must function as a store of value. Full Article

z Biosynthesis of the sactipeptide Ruminococcin C by the human microbiome: Mechanistic insights into thioether bond formation by radical SAM enzymes [Microbiology] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 Despite its major importance in human health, the metabolic potential of the human gut microbiota is still poorly understood. We have recently shown that biosynthesis of Ruminococcin C (RumC), a novel ribosomally synthesized and posttranslationally modified peptide (RiPP) produced by the commensal bacterium Ruminococcus gnavus, requires two radical SAM enzymes (RumMC1 and RumMC2) catalyzing the formation of four Cα-thioether bridges. These bridges, which are essential for RumC's antibiotic properties against human pathogens such as Clostridium perfringens, define two hairpin domains giving this sactipeptide (sulfur-to-α-carbon thioether–containing peptide) an unusual architecture among natural products. We report here the biochemical and spectroscopic characterizations of RumMC2. EPR spectroscopy and mutagenesis data support that RumMC2 is a member of the large family of SPASM domain radical SAM enzymes characterized by the presence of three [4Fe-4S] clusters. We also demonstrate that this enzyme initiates its reaction by Cα H-atom abstraction and is able to catalyze the formation of nonnatural thioether bonds in engineered peptide substrates. Unexpectedly, our data support the formation of a ketoimine rather than an α,β-dehydro-amino acid intermediate during Cα-thioether bridge LC–MS/MS fragmentation. Finally, we explored the roles of the leader peptide and of the RiPP precursor peptide recognition element, present in myriad RiPP-modifying enzymes. Collectively, our data support a more complex role for the peptide recognition element and the core peptide for the installation of posttranslational modifications in RiPPs than previously anticipated and suggest a possible reaction intermediate for thioether bond formation.

z Enhanced enzyme kinetics of reverse transcriptase variants cloned from animals infected with SIVmac239 lacking viral protein X [Microbiology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 HIV Type 1 (HIV-1) and simian immunodeficiency virus (SIV) display differential replication kinetics in macrophages. This is because high expression levels of the active host deoxynucleotide triphosphohydrolase sterile α motif domain and histidine-aspartate domain–containing protein 1 (SAMHD1) deplete intracellular dNTPs, which restrict HIV-1 reverse transcription, and result in a restrictive infection in this myeloid cell type. Some SIVs overcome SAMHD1 restriction using viral protein X (Vpx), a viral accessory protein that induces proteasomal degradation of SAMHD1, increasing cellular dNTP concentrations and enabling efficient proviral DNA synthesis. We previously reported that SAMHD1-noncounteracting lentiviruses may have evolved to harbor RT proteins that efficiently polymerize DNA, even at low dNTP concentrations, to circumvent SAMHD1 restriction. Here we investigated whether RTs from SIVmac239 virus lacking a Vpx protein evolve during in vivo infection to more efficiently synthesize DNA at the low dNTP concentrations found in macrophages. Sequence analysis of RTs cloned from Vpx (+) and Vpx (−) SIVmac239–infected animals revealed that Vpx (−) RTs contained more extensive mutations than Vpx (+) RTs. Although the amino acid substitutions were dispersed indiscriminately across the protein, steady-state and pre-steady-state analysis demonstrated that selected SIVmac239 Vpx (−) RTs are characterized by higher catalytic efficiency and incorporation efficiency values than RTs cloned from SIVmac239 Vpx (+) infections. Overall, this study supports the possibility that the loss of Vpx may generate in vivo SIVmac239 RT variants that can counteract the limited availability of dNTP substrate in macrophages.

z ZBP1 promotes fungi-induced inflammasome activation and pyroptosis, apoptosis, and necroptosis (PANoptosis) [Microbiology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Candida albicans and Aspergillus fumigatus are dangerous fungal pathogens with high morbidity and mortality, particularly in immunocompromised patients. Innate immune-mediated programmed cell death (pyroptosis, apoptosis, necroptosis) is an integral part of host defense against pathogens. Inflammasomes, which are canonically formed upstream of pyroptosis, have been characterized as key mediators of fungal sensing and drivers of proinflammatory responses. However, the specific cell death pathways and key upstream sensors activated in the context of Candida and Aspergillus infections are unknown. Here, we report that C. albicans and A. fumigatus infection induced inflammatory programmed cell death in the form of pyroptosis, apoptosis, and necroptosis (PANoptosis). Further, we identified the innate immune sensor Z-DNA binding protein 1 (ZBP1) as the apical sensor of fungal infection responsible for activating the inflammasome/pyroptosis, apoptosis, and necroptosis. The Zα2 domain of ZBP1 was required to promote this inflammasome activation and PANoptosis. Overall, our results demonstrate that C. albicans and A. fumigatus induce PANoptosis and that ZBP1 plays a vital role in inflammasome activation and PANoptosis in response to fungal pathogens.

z Building a Fantasy Army — Strategy & Organization By mythicscribes.com Published On :: Sun, 06 Jun 2021 20:13:34 +0000 This article is by Toni Šušnjar. Strategy and Enemies The structure of an army will depend on the strategy, as strategy will determine the army’s role and tasks. A state which carries out expansion through outright territorial conquest will have large numbers of heavy infantry, combat engineers and artillery, and possibly some heavy cavalry as well (e.g. Roman Empire, 10th century Byzantine Empire). If conquest is done by slowly destroying an opponent’s economic and social structures through constant raiding (such as chevauchee or razzia / ghazw), then majority of the army will be light cavalry, with some heavy cavalry support (e.g. Seljuk and Ottoman Empires), and light infantry will be used if terrain is unsuitable for cavalry. If a state is defending against cavalry raids, then light cavalry will be dominant (e.g. 15th century Hungary), whereas heavy cavalry will predominate if enemy raiders are primarily infantry. If enemy armies are too powerful to face in the field, light and heavy cavalry will be used to harass the invading army and cut off its supplies and foraging. In terrain unsuitable for cavalry operations, heavy infantry will be used instead. Raiding — as a strategy — is generally preferred against a peer opponent, especially if a state cannot have a developed logistical support system.

z Size of Armies By mythicscribes.com Published On :: Thu, 04 Apr 2024 21:55:08 +0000 Advice for Fantasy Writers This article is by Toni Šušnjar. One of basic elements of fantasy warfare is fantasy army. And one of basic elements of army is its size, which will affect organization and logistics, as well as strategies and tactics it can employ. Thus, prospective fantasy writers should understand factors which limit the size of premodern militaries. But to understand that, it is first to understand differences in what writers mean when they talk of armies. Army vs Field Army Basic difference one has to understand is that of military versus army versus field army. Latter distinction is especially important, and often difficult, as both can be described as simply “army” in sources and thus it is necessary to rely on contextual clues. Military is the overall armed forces of the country. It can include Army or ground forces is the overall land-based forces that the state can control. Field army is a formation of land forces, that is, a portion of land forces deployed as a coherent force under single commander with the aim of achieving a goal.

Here is the link to Part One. Feudal Army Feudal army is a complex beast: it may include landed troops, mercenaries, town militias, conscripted peasants, or any combination of these. Thus estimating size of a feudal army will require estimating size of each element of the listed, and the size of field army will never be an exact proportion of the total military force available – or often even able to be estimated. Landed troops are perhaps easiest to estimate – but even that is not simple. In 15th century Germany, it was generally held that 20 hufen (plots) were required to support a man-at-arms (armored cavalryman) while 10 hufen were required for a lightly armored cavalryman (typically a mounted crossbowman). Hufe was a single peasant’s plot or 121 406 m2. In theory, a state with million men and 85% rural population should have been able to raise 12 750 cavalry, as per the calculation below: 1 000 000 men * 0,85 = 850 000 men = 170 000 plots; lance (gleve) = 1 man at arms + 2 light cavalrymen (note that historically size of lance varied – this is just an example) = 40 plots 170 000 plots = 4 250 lances = 4 250 men-at-arms + 8 500 light cavalrymen This gives a total of 1,275% of population.

z Europe should become the top priority for Liz Truss By www.chathamhouse.org Published On :: Sat, 03 Sep 2022 09:14:33 +0000 Europe should become the top priority for Liz Truss Expert comment NCapeling 3 September 2022 Liz Truss has the chance to be a better prime minister than Boris Johnson was, not least in the UK’s foreign policy. For all the smoke-and-mirrors talk now commonplace about Brexit opportunities, there is real potential that Liz Truss could extract from the aftermath of that upheaval as well as from the turmoil in the world. But the approach and priorities she revealed during her one year as a better UK foreign secretary than Boris Johnson was – although he did set a low bar – as well as the past three months campaigning for the leadership of her party contain a warning. She has shown a willingness to aggravate relationships with allies in pursuit of the support of her party faithful, and of a vision of British independence as well as a tendency to dismiss economic analysis when it inconveniently questions her assertions about favoured policies. At the heart of her political identity is a notion which is both a strength and a potentially calamitous weakness – a love of the notion of being a disrupter which injects a deliberate unpredictability into her approach towards a world in extreme flux. If she indulges this without good judgment, she could do real damage to Britain’s prospects and standing in the world. Ukraine and the energy crisis In foreign policy, Europe should be her starting point and the opportunity here for the UK is clear. The war in Ukraine and crisis in the cost of energy gives it a role – despite having left the European Union (EU) – in talking to EU governments about the future of the continent on many fronts. Johnson’s emphatic support of President Zelensky gave the UK a position of moral and strategic clarity which Truss can build on through what will be an exceptionally difficult winter for Europe’s governments. At the heart of her political identity is a notion which is both a strength and a potentially calamitous weakness – a love of the notion of being a disrupter She is in a position to persuade European leaders to remain united in Ukraine’s support while planning better how they are going to source energy. She could expand on that to help the EU find a way through its many other problems, such as upholding democratic values throughout the bloc or finding a response to migration. There is also a chance for the UK to shape Europe’s thinking on the development and regulation of digital technology and medicine, energy, and the environment. Truss’s declaration that the UK should now spend three per cent of its GDP on defence could help her in taking that kind of role. However this campaign declaration is not yet credible, given the pressures on the national finances and her silence so far on support for households on energy costs. But that is the opportunity in theory and the signs are this is not her approach to Europe. Her provocative and opportunistic comment that the ‘jury’s out’ on whether President Macron (and France) was a friend or foe shocked both Britain’s allies and opponents. For those keen to see divisions among democracies, it gave unexpected, heady encouragement, and to those within those countries, it injected a doubt about shared values which was deeply damaging. The chilly poise of Macron’s response – that the UK and France would always be allies – showed how far she had departed from normal protocol. The episode encapsulated one of the sources of unease about the Truss style – improvisation under the banner of ‘disruption’ without thought of consequences. Her instinctive liking for the US will help Truss in relations with Washington at a difficult time, and her apparent intention to designate China as ‘a threat’ will support that relationship too However, she has shown consistency over the Northern Ireland Protocol with little sign of compromise, and that alone could cause much unnecessary damage to UK interests. It also puts her on a collision course with the EU and the UK House of Lords, due to consider controversial legislation again in early October after the Conservative party conference. There is huge opposition in the Lords to two aspects of the legislation. The first target is the intention of the Johnson government – likely to be repeated by a Truss government – to use the bill to jettison aspects of the protocol, which many argue breaks international law. The second is the delegated power the bill would give ministers. The cost of a new, serious clash – or worse, a full trade war – with the EU is high. There is the loss of trade, the increase in friction for business, which is consistently underestimated by the UK government, and the loss of scientific and research partnerships. More than that, though, there is the weakening of ties to a set of allies with common values sharing an increasingly troubled neighbourhood. US, China, and others remain important And to say Europe should come first is not to dismiss other claims on the UK’s foreign policy. Her instinctive liking for the US will help Truss in relations with Washington at a difficult time, and her apparent intention to designate China as ‘a threat’ will support that relationship too.

z Microtubule affinity-regulating kinase 4 with an Alzheimer's disease-related mutation promotes tau accumulation and exacerbates neurodegeneration [Neurobiology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Accumulation of the microtubule-associated protein tau is associated with Alzheimer's disease (AD). In AD brain, tau is abnormally phosphorylated at many sites, and phosphorylation at Ser-262 and Ser-356 plays critical roles in tau accumulation and toxicity. Microtubule affinity–regulating kinase 4 (MARK4) phosphorylates tau at those sites, and a double de novo mutation in the linker region of MARK4, ΔG316E317D, is associated with an elevated risk of AD. However, it remains unclear how this mutation affects phosphorylation, aggregation, and accumulation of tau and tau-induced neurodegeneration. Here, we report that MARK4ΔG316E317D increases the abundance of highly phosphorylated, insoluble tau species and exacerbates neurodegeneration via Ser-262/356–dependent and –independent mechanisms. Using transgenic Drosophila expressing human MARK4 (MARK4wt) or a mutant version of MARK4 (MARK4ΔG316E317D), we found that coexpression of MARK4wt and MARK4ΔG316E317D increased total tau levels and enhanced tau-induced neurodegeneration and that MARK4ΔG316E317D had more potent effects than MARK4wt. Interestingly, the in vitro kinase activities of MARK4wt and MARK4ΔG316E317D were similar. When tau phosphorylation at Ser-262 and Ser-356 was blocked by alanine substitutions, MARK4wt did not promote tau accumulation or exacerbate neurodegeneration, whereas coexpression of MARK4ΔG316E317D did. Both MARK4wt and MARK4ΔG316E317D increased the levels of oligomeric forms of tau; however, only MARK4ΔG316E317D further increased the detergent insolubility of tau in vivo. Together, these findings suggest that MARK4ΔG316E317D increases tau levels and exacerbates tau toxicity via a novel gain-of-function mechanism and that modification in this region of MARK4 may affect disease pathogenesis.

z The UK must focus on how the Chagos decision is implemented to gain its benefits and minimize risks By www.chathamhouse.org Published On :: Fri, 11 Oct 2024 11:40:15 +0000 The UK must focus on how the Chagos decision is implemented to gain its benefits and minimize risks Expert comment jon.wallace 11 October 2024 The UK decision was welcomed by India and the US, and shows a capacity for fresh thinking. But the transfer of sovereignty must be handled carefully. The UK announced on 3 October that it would cede sovereignty over the Chagos Archipelago to Mauritius.There are potential strategic and reputation-related upsides for the UK from the decision – but these can only be realized if the deal is implemented in ways that meet the UK’s stated goals.First, the UK aims to safeguard the utility and security of the joint US–UK base on Diego Garcia. It also intends for the decision to benefit the Chagossians, who were displaced by the British decision in 1965 to separate the Archipelago from Mauritius as part of a deal to grant Mauritian independence.The decision has already proved deeply controversial in the UK, provoking sustained criticism from former Conservative government ministers and commentary that has branded it naive, dangerous, and a blow to British prestige.Part of the reason for the welter of criticism may be the apparent suddenness of the announcement. The impression that this was a hasty decision is likely because it came just three months after the Labour government came to office. But this belies the far longer gestation period around the decision.World opinionIn fact, the previous Conservative UK government decided to begin negotiations over sovereignty of Chagos – following Mauritius bringing the matter to the International Court of Justice. In 2019, the court issued a non-binding opinion in favour of Mauritius. Related content The new government must work hard to restore the UK’s reputation as a champion of international law The same year the UN General Assembly voted 116 in favour to 6 against, and with 56 abstentions, for a resolution ‘welcoming a 25 February 2019 International Court of Justice advisory opinion on the legal consequences of separating the Chagos Archipelago from Mauritius in 1965, demanding that the UK unconditionally withdraw its colonial administration from the area within six months’ to ‘enable Mauritius to complete the decolonization of its territory.’But returning the islands will not necessarily boost the UK’s international standing. Issues relating to the Archipelago are complex, and it will take work to convince interested international parties that the UK is acting fairly against a colonized and displaced population.Mauritius has no pre-colonial history of controlling the Chagos islands, which are located some 1,500 miles away from Mauritius across a vast sprawl of the Indian Ocean. It is true that the Chagos Islands were a colonial remnant, but to ensure that UK is seen by global audiences to be acting fairly, the handover of sovereignty must be carefully handled. Perhaps the greatest reputational risk will come from failing to adequately account for the rights of Chagossians. The more pertinent historical injustice has been to them. And reporting by the BBC has shown that at least some Chagossians were dismayed by not having been consulted in negotiations between the UK and Mauritius. This deal was reached in close consultation with US officials and puts the (Diego Garcia) base on legally safe ground for the first time in decades. The UK government announcement on the deal did state that that ‘the welfare of Chagossians’ will be paramount and that ‘the UK will capitalize a new trust fund, as well as separately provide other support, for the benefit of Chagossians’. But for the Chagossians, there will be a clamour to see this realized in full.Strategic interestsOn the strategic question, the utility of the joint US–UK military base on Diego Garcia has been guaranteed in a 99-year lease. As the UK negotiator Jonathan Powell has explained, this deal was reached in close consultation with US officials and puts the base on legally safe ground for the first time in decades. Indeed, Powell has explained that Joe Biden was keen to reach agreement ahead of the US elections so that US military access to Diego Garcia was safeguarded against any possible contrary decision by a possible returning Trump presidency.There are understandable concerns that, as a result of the decision, China may develop commercial ports in the region and seek to compete with India for economic and strategic relationships. But this is a long-term matter of concern to monitor, regardless of the UK’s decision on Chagos. Related content The UK needs an India strategy that goes beyond the trade deal Chinese naval influence in the Indian Ocean is currently limited, compared to its assertiveness in the South China Sea, where it is building artificial islands, or in the South Pacific where it is pursuing policing assistance deals like that secured with the Solomon Islands.And the strategic situations in the Pacific and Indian Oceans are not at all alike. Indeed, the Chagos Islands are far closer to India and its economic influence than they are to any other major economic power. The fact that India has welcomed the UK’s decision over Chagos sovereignty is noteworthy, given the UK’s separate attempts to modernize and expand its bilateral relations with New Delhi.In the long run, it is likely that India will play a leading role in Indian Ocean security, and the UK will want to be well-placed to explore how to play a role as an effectively partner. There are legitimate questions to be raised over setting a precedent that could undermine RAF Akrotiri and Dhekelia in Cyprus. The more pertinent immediate concern is the implications for other overseas UK territorial responsibilities. There are legitimate questions to be raised over setting a precedent that could undermine RAF Akrotiri and Dhekelia in Cyprus, which remained sovereign UK bases after Cyprus’s independence in 1960.

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

z The break-up of Scholz’s coalition government signals the end of Germany’s old economic model By www.chathamhouse.org Published On :: Tue, 12 Nov 2024 15:12:46 +0000 The break-up of Scholz’s coalition government signals the end of Germany’s old economic model Expert comment jon.wallace 12 November 2024 The coalition could not agree how to fund new support for Ukraine and failed to fully implement the ‘Zeitenwende’. A new government must push through reform. As Europeans were still processing Donald Trump’s victory in the 2024 US presidential election, an acrimonious break up occurred 4000 miles east of Washington DC.Reports had been circulating for weeks about the fragile state of Germany’s ‘traffic light’ coalition government led by German Chancellor Olaf Scholz, consisting of the centre-left Social Democratic Party (SPD), the Green Party, and liberal Free Democratic Party (FDP).The expectation had been that the coalition would hold on for a few more weeks and might even be given a new lease of life by Trump’s re-election. Instead, it collapsed on the day Trump’s win was confirmed. An unusually angry Scholtz announced in a live address that he had fired FDP Finance Minister Christian Lindner, effectively breaking up the coalition. Related content Independent Thinking: Can Germany lead in a divided Europe? At the heart of the dispute was the so-called ‘debt brake’ – a constitutional mechanism which restricts Germany’s annual public deficit to 0.35 per cent of GDP. Lindner proposed a set of reforms which were unpalatable to the SPD and the Greens. In response, Scholz suggested declaring an emergency, which would have suspended the debt brake. That in turn was unacceptable to Lindner, leading to his sacking by the Chancellor.Practically, this means the SPD and the Greens are now in a minority coalition, without agreement on the 2025 budget or the votes in parliament to pass it. They also still face the challenge of the debt brake.A vote of confidence will take place in December, with elections to be held before the end of February 2025 latest.The end of Germany’s economic modelAt the root of Germany’s political crisis is the country’s economic model. For decades, Germany relied on a system that depended on cheap Russian gas, cheap imports of consumer goods from China, high-value exports – particularly in the automotive sector – and the US security umbrella.With Russian energy no longer viable, the global economic landscape shifting, and Donald Trump on his way back to the White House, that model is no longer workable. And Germany’s economy is expected to contract by 0.2 per cent in 2024 – a contraction for the second year running. Germany has struggled to turn around its economic woes, with the car industry particularly affected. The ‘Zeitenwende’, announced by Scholz in the wake of Russia’s full-scale invasion of Ukraine, should have signalled a turnaround of both foreign and economic policy, given how much the two are interconnected. Yet on both fronts, too little changed.Germany’s reliance on Russian gas did come to an abrupt end in 2022. And Germany is Ukraine’s second largest military aid donor after the US, while accepting the most Ukrainian refugees.But the ‘Zeitenwende’ turnaround ended there. Scholz’s coalition government failed to prepare for long-term investment in defence at the levels required by creating an off-budget defence spending fund which would have run out in 2027. The draft budget for 2025 showed defence spending would have been cut, as would support for Ukraine.Germany has also struggled to turn around its economic woes, with the car industry particularly affected. Cheap Chinese EVs and new energy technologies are competing with Germany’s most powerful companies. Volkswagen, the country’s largest car manufacturer, has announced plant closures and layoffs due to shrinking profit margins. To the west, Trump’s threat to impose 10 to 20 per cent tariffs on all EU imports meant share prices of Volkswagen, BMW, Mercedez-Benz and Porsche all dropped between 4 to 7 per cent following news of his re-election.To the east, trade tensions between the EU and China are intensifying. Yet rather than choosing to diversify, German companies have doubled down on their bets in China, with German investment in the country rising from €6.5bn for the whole of 2023 to €7.3bn in the first half of 2024 alone – only exposing carmakers further.Germany’s support for UkraineLike French President Emmanuel Macron, Scholz had already been weakened by the results of the European Parliamentary elections in June. With the collapse of his traffic light coalition, the EU’s Franco-German ‘engine’ is now well and truly stalled – until new leadership can be found. This weakness comes at a perilous moment when clear, united European leadership, and much increased funding, is needed to shore up support for Ukraine. Full Article
