block Nicolas Hafner: Creative Block - May Kandria Update By reader.tymoon.eu Published On :: Sun, 03 May 2020 16:31:18 GMT It's a new month, and that usually means I'm supposed to write a monthly update on the progress with Kandria. Thinking about that though made me feel very depressed because I realised that I hadn't really done anything at all for the game, all of April. I can blame however much I want of that on the quarantine and university stress, or whatever else, but it won't change the fact that there has not been much progress on any front. While I have been slacking a lot, it's not like I haven't been working at all - plenty of time has gone into Courier, after all. When I had this realisation yesterday, I tried my best to push myself to work on the game any way I could, but I failed to find anything that I could actually convince myself to do. That isn't to say that there aren't things to do; god forbid there's a tonne of things! Tuning combat, drawing animations, writing the UI, fixing dialogue, starting on enemy AI, optimising performance - just to name a few. And yet, despite the breadth and depth of things to do, there was absolutely nothing that looked appealing to me. This kind of feeling is nothing new to me. It's a creative block, and happens more often that I'd like to admit. It's also why I often don't like to start long running projects, because I'm afraid of a creative block that would ruin it. The worst part about the creative block is that there's no remedy for it. You just get stuck in a rut, and it sucks a whole lot for a completely unpredictable amount of time. Often what I end up doing, whether consciously so or not, is switching to another project and just working on that. So far that project has been Courier, but that's at its end and I'm also starting to feel burnt out on it, too. I don't have any other projects queued up that I'd like to tackle, or new ideas on what to do at the moment, so I'm just... stuck. I suppose the right thing to do in this situation is to take it easy and not fret too much over it, since that's often one of the many factors causing the block. I've never been good at actually doing that, though. Maybe I should try to take a break from programming in general? I don't know. You may be wondering why I'm writing this all to begin with. Well, partly I feel like I promised to do monthly and weekly updates, and I really hate to break that promise without notice. Another part is that I just feel like I owe you the discretion to tell you what's going on with me. I'm very thankful for the email replies and general responses I've gotten for Kandria so far, I really am! Because of that genuine interest, I feel all the more pressured not to disappoint. Since I have nothing to show though, I thought the only proper course of action is to just be open and direct about it. So I'll just say it again: aside from updating the public demo, no progress has been made at all. Maybe it would help me to have a more open discussion about this topic in general, instead of just it being me telling you that I'm in a bad place. So please, let me know: have you been in similar situations before? What helped you deal with them? Is there something in Kandria I could try to focus on that you, personally, would like to see?

block Applications of Blockchain to Programming Language Theory By lambda-the-ultimate.org Published On :: Mon, 13 Apr 2020 14:38:12 +0000 Let's talk about Blockchain. Goal is to use this forum topic to highlight its usefulness to programming language theory and practice. If you're familiar with existing research efforts, please share them here. In addition, feel free to generate ideas for how Blockchain could improve languages and developer productivity. As one tasty example: Blockchain helps to formalize thinking about mutual knowledge and common knowledge, and potentially think about sharing intergalactic computing power through vast distributed computing fabrics. If we can design contracts in such a way that maximizes the usage of mutual knowledge while minimizing common knowledge to situations where you have to "prove your collateral", third-party transactions could eliminate a lot of back office burden. But, there might be benefits in other areas of computer science from such research, as well. Some language researchers, like Mark S. Miller, have always dreamed of Agoric and the Decades-Long Quest for Secure Smart Contracts. Some may also be aware that verification of smart contracts is an important research area, because of the notorious theft of purse via logic bug in an Ethereum smart contract.

block A blockbuster Facebook office deal is a make-or-break moment for the future of commercial real estate. 3 leasing experts lay out the stakes. By feedproxy.google.com Published On :: Sat, 09 May 2020 07:47:00 -0400 Facebook has been in negotiations for months to lease over 700,000 square feet at the Farley Building on Manhattan's West Side. Office leasing activity in the city has plummeted, giving the blockbuster deal even more importance as a sign of life in a suddenly lethargic market. The coronavirus has spurred a deep downturn in the economy that is already being felt in the city's commercial real-estate market, prompting a big slowdown in leasing activity. The rapid expansion of tech in recent years has propelled the city's office market. Real estate execs say that Facebook's big deal is a key barometer. The crisis also raises questions whether tenants will ever occupy office space the same way as companies and their workforces around the world grow familiar with remote work. Click here for more BI Prime stories. Leasing activity in New York City's multi-billion-dollar commercial office market has dropped precipitously as the coronavirus has battered the market and raised questions of when — and even if — tenants can return to the workplace in a post-Covid world. Amid the growing concerns the crisis will smother what had been robust demand for office space, eyes in the city's real estate industry have turned to a pending blockbuster deal on the West Side that could offer a signal of confidence to the market. Facebook is in talks to take over 700,000 square feet of space in the Farley Building, a block-long property across Eighth Avenue from Penn Station. "If that deal happens, then this market will be just fine," said Peter Riguardi, the New York area chairman and president of JLL. "If the deal happens but it's renegotiated, it will be fine, but it will be a trend that every tenant can follow. And if it doesn't happen, I would be very concerned about the market."

Facebook's NYC real-estate footprint Last year, Facebook signed on for 1.5 million square feet in the Hudson Yards mega-development just west of the Farley Building, taking space in three new office towers at the project. For months the $600 billion Silicon Valley-based social media giant has been in negotiations for even more space at the nearby Farley Building, whose interior landlord Vornado Realty Trust is redeveloping to include newly built office and retail space. Vornado had originally expected to complete the deal with Facebook in early March, according to a source familiar with the negotiations. The talks have continued on as the virus pandemic has brought commerce and social life to a virtual halt. The source expected the lease, which will commit Facebook to pay hundreds of millions of dollars in rent for the space over the life of the lease, to soon be completed. In a conference call with investors and analysts on Tuesday to discuss Vornado's first-quarter earnings, the company's CEO Steve Roth also hinted that the Facebook deal was still on track. "There's another large tenant that has been rumored to be that we've been in dialogue with," Roth said, not directly naming the company. "That conversation is going forward aggressively and hopefully maybe even almost complete." Rapid growth in Big Tech leasing before coronavirus Recent real-estate decisions by Facebook and other tech companies have worried real-estate executives that they may reconsider their footprint after years of dramatic growth. Facebook on Thursday revealed that the bulk of its over 40,000-person workforce will be asked to work remotely for the remainder of the year, a timeline that appears to show the company is using caution in returning to its footprint. Read More: Neiman Marcus just filed for bankruptcy, and it could mark a major blow to NYC's glitzy Hudson Yards — one of the most expensive mega-malls in US history. Here's why. Real-estate executives have expressed concern that tenants may become accustomed to offloading a portion or even the bulk of their workforce to a remote-working model, leading them to drastically reduce their office commitments. At a minimum, the economic upheaval has appeared to spur a newfound sense of caution in tech companies that have grown rapidly in recent years. Alphabet called off negotiations to expand its San Francisco offices by over 2 million square feet in recent weeks, according to a report from The Information. Tech has been a big driver of demand for office space In recent years the tech industry had become one of the most voracious takers of space in the city, helping to push up commercial rents and spur the construction of new office space. In 2019, tech firms accounted for 24.5% of the 31.6 million square feet of leasing activity in Manhattan, eclipsing the financial industry as the city's biggest space-taking sector for the first time, according to data from the real estate services and brokerage firm CBRE. In 2010 tech leasing comprised just 4% of the 24.2 million square feet that was leased in the Manhattan market that year, CBRE said. "Nothing has buoyed the confidence of landlords more in recent years than tech tenants," said Sacha Zarba, a leasing executive at CBRE who specializes in working with tech firms. "It didn't matter where your building was. If it was attractive to tech, you would stand a good chance to lease your space. If that industry retrenches a bit, it removes a big driver of demand." The Manhattan office market has slowed rapidly in recent weeks as the virus crisis has battered the economy and shut down daily life. About 844,000 square feet of space was leased in Manhattan in April, according to CBRE, 64% lower than the five-year monthly average. In the first four months of the year, nearly seven million square feet was leased, a decline of 30% for the same period a year ago. So far, however, there are signs that tech continues to snap up space. After scuttling plans to develop a 25,000 person second headquarters space in Long Island City last year, Amazon purchased 424 Fifth Avenue, a former flagship department store for Lord & Taylor, for nearly $1 billion in March. That property totals about 660,000 square feet. Late last year, before the pandemic hit U.S. shores but had flared in China, Amazon also leased 335,000 square feet at 410 Tenth Avenue. The commitments of major tech companies absorb millions of square feet in the city, but they also help fuel a larger ecosystem of tenants that occupies an even larger footprint. That means that a decrease in the real estate of just a few big tech players could be multiplied across the market as smaller players in the sector follow suit."Those big tech firms do a fantastic job of training and credentialing tech talent on the city," said Matt Harrigan, a co-founder of Company, a space incubator at 335 Madison Avenue that provides offices and community for both startups and more established tech firms. "Google and Facebook spin off talent who start or join other tech ventures that take space. That's what's so important about having the large presence of those companies here." Have a tip?

block How Qatar’s Food System Has Adapted to the Blockade By feedproxy.google.com Published On :: Thu, 14 Nov 2019 14:43:46 +0000 14 November 2019 Laura Wellesley Research Fellow, Energy, Environment and Resources Programme @laurawellesley Two-and-a-half years on from the imposition of a trade blockade against Qatar by the Arab Quartet, Qatar’s food system has undergone a remarkable transformation – but it is one that brings new risks to Qatar’s future food and resource security. 2019-11-14-QatarCows.jpg Cows are are fed at a dairy factory at Baladna farm in al-Khor, Qatar. Photo: Karim Jaafar/AFP via Getty Images. Earlier this month, Sheikh Tamim – the emir of Qatar – hailed the country’s success in overcoming the impacts of the embargo levied by the so-called Arab Quartet – Bahrain, Egypt, Saudi Arabia and the United Arab Emirates (UAE). Qatar will post a budget surplus for the first time in three years, and the country’s long-term plan for economic diversification has taken great strides, according to the emir. Key among the achievements cited was the advancement of Qatar’s domestic food industry.When the blockade was introduced in June 2017, it threw the vulnerability of Qatar’s domestic food supply to outside interruption into sharp relief. Qatar is poorly suited to growing food. The desert country ranks as the most water-stressed in the world. As one of the hottest, most arid countries in the world, trade is critical to feeding the nation; over 90 per cent of its food supply is imported.Most of Qatar’s cereal imports – including 80 per cent of its wheat supply – arrive by sea from exporters including India, Russia and Australia. Sitting on the eastern edge of the Persian Gulf, Qatar’s only maritime gateway to the world is the Strait of Hormuz. This narrow body of water can, as events this summer have shown, be disrupted by geopolitical events. But for 40 per cent of overall food imports, overland trade from Saudi Arabia was Qatar’s primary supply channel before June 2017 – particularly so for dairy products and fresh fruit and vegetables coming from the EU, Turkey and Jordan.The abrupt closure of Saudi Arabia’s borders prompted significant private investment in Qatar’s own food industry; domestic production has reportedly increased four-fold since the blockade was introduced. Prior to the blockade, Qatar imported 85 per cent of its vegetables; it now hopes to produce 60 per cent within the next three years. Perhaps even more remarkably, the country is now self-sufficient in dairy, having previously relied on imports for 72 per cent of its supply.This progress has come at a cost. Qatar’s booming domestic industry is highly resource-intensive. To fill the gap in the dairy sector, Baladna – the country’s principal dairy producer – imported around 18,000 Holstein dairy cows from the EU and US. The company is thriving; in June of this year, it made its first dairy exports.But the desert is not a natural environment for these cows; they must be kept indoors, at temperatures around 15°C cooler than the outside air, and misted with water to prevent overheating. The cooling systems are a huge drain on local resources. Each dairy cow requires an average of 185 gallons of water a day, almost twice the volume used by the average Qatari household. The majority of this water comes from oil- or gas-powered desalination plants; the cooling systems themselves run on gas-fired electricity.Qatar has traditionally invested in production overseas – particularly in Sudan and Tanzania – to secure its fodder supply, but the government has plans to become self-sufficient in fodder crops such as lucerne (alfalfa) and Rhodes grass. This will require irrigation on a vast scale. Qatar’s farmland is mostly located in the north of the country where it benefits from aquifers; fodder production already accounts for half of the groundwater extracted for use in agriculture.Despite commitments made under the National Food Security Programme to improving the water efficiency of Qatar’s food production, the rate of draw-down of these aquifers exceeds their recharge rates. Overexploitation has resulted in saline intrusion, threatening their long-term viability. With 92 per cent of all extracted groundwater given to farmers free of charge, there is little incentive for economizing on its use.Increasing production will also likely mean increasing fertilizer use; rates of fertilizer use in Qatar are among the highest in the world, second only to those in Singapore.Both government and industry are taking small steps to ‘green’ the country’s food production. Certain local authorities plan to ban the use of groundwater for fodder production by 2025, requiring producers to use treated sewage water instead and reserving the use of groundwater for crop production.A number of companies are also adopting so-called ‘circular’ practices to achieve more efficienct resource use; Agrico, a major vegetable producer, has expanded its organic hydroponics operations, a move the company reports has led to a 90 per cent reduction in water use. But, with a target to produce up to 50 per cent of Qatar’s fresh food supply domestically within just a few years, scattered examples of resource-saving strategies will not be enough to mitigate the rise in water demand.As Qatar looks to continue growing its food industry in the wake of the blockade, it is from Saudi Arabia – ironic though it may be – that Qatar stands to learn important lessons.Saudi Arabia’s scaling up of domestic wheat production – initially to achieve self-sufficiency and then to support a prosperous export industry – was ultimately a failed effort. The unsustainable extraction of groundwater – fuelled by generous subsidies for wheat producers and the nominal cost of diesel for pumping – brought the country’s water table to the brink of collapse, and the government was forced to make a dramatic U-turn, reducing then removing the subsidies and shrinking its wheat sector.The UAE also provides an instructive example for how domestic food production may be supported – this time positive. This summer, the Department of Environment in Abu Dhabi announced its Recycled Water Policy, laying out a policy framework to promote and facilitate reused water across all major sectors, including agriculture.Back in 2014, the Ministry of Climate Change and Environment set hydroponics as a key priority, launching a 100 million Emirati dirham fund to incentivize and support farmers establishing hydroponic farms. And the International Center for Biosaline Agriculture, based in Dubai and supported by the UAE government, undertakes pioneering research into sustainable food production in saline environments.On the face of it, Qatar has indeed bounced back from the blockade. As and when cross-border trade is re-established with Saudi Arabia, Qatar will boast a more diverse – and more resilient – network of trade relationships than it did prior to June 2017.In addition to investment in domestic food production, the blockade also provoked a rapid recalibration of Qatar’s trade relationships. Allies in the region – most notably Turkey and Iran – were quick to come to Qatar’s assistance, delivering fresh produce by air. Since then, Qatar has scaled up its trading relationship with both countries.It has also leveraged its position as the world’s largest exporter of liquid natural gas to establish new maritime trade lines with major food exporters, including India. Should tensions spike again in the future, it will be in a stronger position to weather the storm.But, in the absence of a commitment to support the widespread adoption of circular agricultural technologies and practices, Qatar’s commitment to increasing its self-sufficiency and expanding its domestic production could ultimately undermine its long-term food security.Rising average temperatures and increasingly frequent extreme weather events – like the heatwave in 2010 when temperatures soared to over 50°C – will exacerbate already high resource stress in the country. Unsustainable exploitation of finite land, water and energy reserves will limit the country’s long-term capacity to produce food and weaken its ability to withstand future disruptions to regional and international supply channels.As Qatar continues in its efforts to secure a reliable food supply, it would do well to heed the experience of its neighbours, be they friend or foe.

block Chemical roadblocking of DNA transcription for nascent RNA display [RNA] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Site-specific arrest of RNA polymerases (RNAPs) is fundamental to several technologies that assess RNA structure and function. Current in vitro transcription “roadblocking” approaches inhibit transcription elongation by blocking RNAP with a protein bound to the DNA template. One limitation of protein-mediated transcription roadblocking is that it requires inclusion of a protein factor extrinsic to the minimal in vitro transcription reaction. In this work, we developed a chemical approach for halting transcription by Escherichia coli RNAP. We first established a sequence-independent method for site-specific incorporation of chemical lesions into dsDNA templates by sequential PCR and translesion synthesis. We then show that interrupting the transcribed DNA strand with an internal desthiobiotin-triethylene glycol modification or 1,N6-etheno-2'-deoxyadenosine base efficiently and stably halts Escherichia coli RNAP transcription. By encoding an intrinsic stall site within the template DNA, our chemical transcription roadblocking approach enables display of nascent RNA molecules from RNAP in a minimal in vitro transcription reaction.

The cooling systems are a huge drain on local resources. Each dairy cow requires an average of 185 gallons of water a day, almost twice the volume used by the average Qatari household. The majority of this water comes from oil- or gas-powered desalination plants; the cooling systems themselves run on gas-fired electricity.Qatar has traditionally invested in production overseas – particularly in Sudan and Tanzania – to secure its fodder supply, but the government has plans to become self-sufficient in fodder crops such as lucerne (alfalfa) and Rhodes grass. This will require irrigation on a vast scale. Qatar’s farmland is mostly located in the north of the country where it benefits from aquifers; fodder production already accounts for half of the groundwater extracted for use in agriculture.Despite commitments made under the National Food Security Programme to improving the water efficiency of Qatar’s food production, the rate of draw-down of these aquifers exceeds their recharge rates. Overexploitation has resulted in saline intrusion, threatening their long-term viability. With 92 per cent of all extracted groundwater given to farmers free of charge, there is little incentive for economizing on its use.Increasing production will also likely mean increasing fertilizer use; rates of fertilizer use in Qatar are among the highest in the world, second only to those in Singapore.Both government and industry are taking small steps to ‘green’ the country’s food production. Certain local authorities plan to ban the use of groundwater for fodder production by 2025, requiring producers to use treated sewage water instead and reserving the use of groundwater for crop production.A number of companies are also adopting so-called ‘circular’ practices to achieve more efficienct resource use; Agrico, a major vegetable producer, has expanded its organic hydroponics operations, a move the company reports has led to a 90 per cent reduction in water use. But, with a target to produce up to 50 per cent of Qatar’s fresh food supply domestically within just a few years, scattered examples of resource-saving strategies will not be enough to mitigate the rise in water demand.As Qatar looks to continue growing its food industry in the wake of the blockade, it is from Saudi Arabia – ironic though it may be – that Qatar stands to learn important lessons.Saudi Arabia’s scaling up of domestic wheat production – initially to achieve self-sufficiency and then to support a prosperous export industry – was ultimately a failed effort. The unsustainable extraction of groundwater – fuelled by generous subsidies for wheat producers and the nominal cost of diesel for pumping – brought the country’s water table to the brink of collapse, and the government was forced to make a dramatic U-turn, reducing then removing the subsidies and shrinking its wheat sector.The UAE also provides an instructive example for how domestic food production may be supported – this time positive. This summer, the Department of Environment in Abu Dhabi announced its Recycled Water Policy, laying out a policy framework to promote and facilitate reused water across all major sectors, including agriculture.Back in 2014, the Ministry of Climate Change and Environment set hydroponics as a key priority, launching a 100 million Emirati dirham fund to incentivize and support farmers establishing hydroponic farms. And the International Center for Biosaline Agriculture, based in Dubai and supported by the UAE government, undertakes pioneering research into sustainable food production in saline environments.On the face of it, Qatar has indeed bounced back from the blockade. As and when cross-border trade is re-established with Saudi Arabia, Qatar will boast a more diverse – and more resilient – network of trade relationships than it did prior to June 2017.In addition to investment in domestic food production, the blockade also provoked a rapid recalibration of Qatar’s trade relationships. Allies in the region – most notably Turkey and Iran – were quick to come to Qatar’s assistance, delivering fresh produce by air. Since then, Qatar has scaled up its trading relationship with both countries.It has also leveraged its position as the world’s largest exporter of liquid natural gas to establish new maritime trade lines with major food exporters, including India. Should tensions spike again in the future, it will be in a stronger position to weather the storm.But, in the absence of a commitment to support the widespread adoption of circular agricultural technologies and practices, Qatar’s commitment to increasing its self-sufficiency and expanding its domestic production could ultimately undermine its long-term food security.Rising average temperatures and increasingly frequent extreme weather events – like the heatwave in 2010 when temperatures soared to over 50°C – will exacerbate already high resource stress in the country. Unsustainable exploitation of finite land, water and energy reserves will limit the country’s long-term capacity to produce food and weaken its ability to withstand future disruptions to regional and international supply channels.As Qatar continues in its efforts to secure a reliable food supply, it would do well to heed the experience of its neighbours, be they friend or foe.

block Exact recovery in block spin Ising models at the critical line By projecteuclid.org Published On :: Thu, 23 Apr 2020 22:01 EDT Matthias Löwe, Kristina Schubert. Source: Electronic Journal of Statistics, Volume 14, Number 1, 1796--1815.Abstract: We show how to exactly reconstruct the block structure at the critical line in the so-called Ising block model. This model was recently re-introduced by Berthet, Rigollet and Srivastava in [2]. There the authors show how to exactly reconstruct blocks away from the critical line and they give an upper and a lower bound on the number of observations one needs; thereby they establish a minimax optimal rate (up to constants). Our technique relies on a combination of their methods with fluctuation results obtained in [20]. The latter are extended to the full critical regime. We find that the number of necessary observations depends on whether the interaction parameter between two blocks is positive or negative: In the first case, there are about $Nlog N$ observations required to exactly recover the block structure, while in the latter case $sqrt{N}log N$ observations suffice.

block Rate optimal Chernoff bound and application to community detection in the stochastic block models By projecteuclid.org Published On :: Tue, 24 Mar 2020 22:01 EDT Zhixin Zhou, Ping Li. Source: Electronic Journal of Statistics, Volume 14, Number 1, 1302--1347.Abstract: The Chernoff coefficient is known to be an upper bound of Bayes error probability in classification problem. In this paper, we will develop a rate optimal Chernoff bound on the Bayes error probability. The new bound is not only an upper bound but also a lower bound of Bayes error probability up to a constant factor. Moreover, we will apply this result to community detection in the stochastic block models. As a clustering problem, the optimal misclassification rate of community detection problem can be characterized by our rate optimal Chernoff bound. This can be formalized by deriving a minimax error rate over certain parameter space of stochastic block models, then achieving such an error rate by a feasible algorithm employing multiple steps of EM type updates.

block Consistency and asymptotic normality of Latent Block Model estimators By projecteuclid.org Published On :: Mon, 23 Mar 2020 22:02 EDT Vincent Brault, Christine Keribin, Mahendra Mariadassou. Source: Electronic Journal of Statistics, Volume 14, Number 1, 1234--1268.Abstract: The Latent Block Model (LBM) is a model-based method to cluster simultaneously the $d$ columns and $n$ rows of a data matrix. Parameter estimation in LBM is a difficult and multifaceted problem. Although various estimation strategies have been proposed and are now well understood empirically, theoretical guarantees about their asymptotic behavior is rather sparse and most results are limited to the binary setting. We prove here theoretical guarantees in the valued settings. We show that under some mild conditions on the parameter space, and in an asymptotic regime where $log (d)/n$ and $log (n)/d$ tend to $0$ when $n$ and $d$ tend to infinity, (1) the maximum-likelihood estimate of the complete model (with known labels) is consistent and (2) the log-likelihood ratios are equivalent under the complete and observed (with unknown labels) models. This equivalence allows us to transfer the asymptotic consistency, and under mild conditions, asymptotic normality, to the maximum likelihood estimate under the observed model. Moreover, the variational estimator is also consistent and, under the same conditions, asymptotically normal. Full Article
block Weighted Message Passing and Minimum Energy Flow for Heterogeneous Stochastic Block Models with Side Information By Published On :: 2020 We study the misclassification error for community detection in general heterogeneous stochastic block models (SBM) with noisy or partial label information. We establish a connection between the misclassification rate and the notion of minimum energy on the local neighborhood of the SBM. We develop an optimally weighted message passing algorithm to reconstruct labels for SBM based on the minimum energy flow and the eigenvectors of a certain Markov transition matrix. The general SBM considered in this paper allows for unequal-size communities, degree heterogeneity, and different connection probabilities among blocks. We focus on how to optimally weigh the message passing to improve misclassification. Full Article
block Optimal rates for community estimation in the weighted stochastic block model By projecteuclid.org Published On :: Mon, 17 Feb 2020 04:02 EST Min Xu, Varun Jog, Po-Ling Loh. Source: The Annals of Statistics, Volume 48, Number 1, 183--204.Abstract: Community identification in a network is an important problem in fields such as social science, neuroscience and genetics. Over the past decade, stochastic block models (SBMs) have emerged as a popular statistical framework for this problem. However, SBMs have an important limitation in that they are suited only for networks with unweighted edges; in various scientific applications, disregarding the edge weights may result in a loss of valuable information. We study a weighted generalization of the SBM, in which observations are collected in the form of a weighted adjacency matrix and the weight of each edge is generated independently from an unknown probability density determined by the community membership of its endpoints. We characterize the optimal rate of misclustering error of the weighted SBM in terms of the Renyi divergence of order 1/2 between the weight distributions of within-community and between-community edges, substantially generalizing existing results for unweighted SBMs. Furthermore, we present a computationally tractable algorithm based on discretization that achieves the optimal error rate. Our method is adaptive in the sense that the algorithm, without assuming knowledge of the weight densities, performs as well as the best algorithm that knows the weight densities. Full Article
block Local law and Tracy–Widom limit for sparse stochastic block models By projecteuclid.org Published On :: Mon, 27 Apr 2020 04:02 EDT Jong Yun Hwang, Ji Oon Lee, Wooseok Yang. Source: Bernoulli, Volume 26, Number 3, 2400--2435.Abstract: We consider the spectral properties of sparse stochastic block models, where $N$ vertices are partitioned into $K$ balanced communities. Under an assumption that the intra-community probability and inter-community probability are of similar order, we prove a local semicircle law up to the spectral edges, with an explicit formula on the deterministic shift of the spectral edge. We also prove that the fluctuation of the extremal eigenvalues is given by the GOE Tracy–Widom law after rescaling and centering the entries of sparse stochastic block models. Applying the result to sparse stochastic block models, we rigorously prove that there is a large gap between the outliers and the spectral edge without centering. Full Article
block Consistent structure estimation of exponential-family random graph models with block structure By projecteuclid.org Published On :: Fri, 31 Jan 2020 04:06 EST Michael Schweinberger. Source: Bernoulli, Volume 26, Number 2, 1205--1233.Abstract: We consider the challenging problem of statistical inference for exponential-family random graph models based on a single observation of a random graph with complex dependence. To facilitate statistical inference, we consider random graphs with additional structure in the form of block structure. We have shown elsewhere that when the block structure is known, it facilitates consistency results for $M$-estimators of canonical and curved exponential-family random graph models with complex dependence, such as transitivity. In practice, the block structure is known in some applications (e.g., multilevel networks), but is unknown in others. When the block structure is unknown, the first and foremost question is whether it can be recovered with high probability based on a single observation of a random graph with complex dependence. The main consistency results of the paper show that it is possible to do so under weak dependence and smoothness conditions. These results confirm that exponential-family random graph models with block structure constitute a promising direction of statistical network analysis. Full Article

block US group calls Pakistan blocking of aid to Christians, Hindus 'reprehensible' By feedproxy.google.com Published On :: Wed, 15 Apr 2020 15:30:00 -0600 CNA Staff, Apr 15, 2020 / 03:30 pm (CNA).- The U.S. Commission on Religious Freedom has called on the Pakistani government to ensure aid for the COVID-19 pandemic is being justly distributed to religious minorities, after receiving reports that aid organizations were barring Christians and Hindus from receiving food assistance. “These actions are simply reprehensible,” USCIRF Commissioner Anurima Bhargava said in an April 13 statement. “As COVID-19 continues to spread, vulnerable communities within Pakistan are fighting hunger and to keep their families safe and healthy. Food aid must not be denied because of one’s faith. We urge the Pakistani government to ensure that food aid from distributing organizations is shared equally with Hindus, Christians, and other religions minorities,” she said. According to the commission, recent reports have shown that in Karachi a non-government aid organization, the Saylani Welfare International Trust, has been denying food assistance to Christians and Hindus, telling them that the aid was reserved for Muslims. Pakistan’s state religion is Islam, and around 97 percent of the population is Muslim. The authorities of Pakistan have consistently failed to implement safeguards on behalf of religious minorities, despite numerous policies in favor of economic and physical protections for members of non-Muslim religions. For example, the country has promised to provide quotas for employment to ensure that religious minorities are granted equal access to jobs, but so far it has not done so. Additionally, strict blasphemy laws in the country are reportedly used to settle scores or to persecute religious minorities. While non-Muslims constitute only 3 percent of the Pakistani population, 14 percent of blasphemy cases have been levied against them. In a recent highly publicized case, Asia Bibi, a Christian mother of five, spent eight years on death row on blasphemy charges after being accused of making disparaging remarks about Muhammad after an argument stemming from a cup of water. Amid strong international pressure, the Pakistan Supreme Court acquitted her in late 2018. A 2019 report from USCIRF found that Christians and Hindus “face continued threats to their security and are subject to various forms of harassment and social exclusion,” the USCIRF statement said. The country was also designated by the US Department of State as a “Country of Particular Concern” in December 2018 for its poor religious freedom record. USCIRF Commissioner Johnnie Moore noted in the April 13 statement that in a recent address to the international community, Prime Minister Imran Khan said that governments in developing countries must work to save people from starvation during the coronavirus pandemic. Pakistan’s health ministry has reported nearly 6,000 cases of coronavirus in the country of 212 million people as of April 15. “This is a monumental task laying before many countries. Prime Minister Khan’s government has the opportunity to lead the way but they must not leave religious minorities behind,” he said. “Otherwise, they may add on top of it all one more crisis, created by religious discrimination and inter-communal strife.” A March 2020 report from USCIRF noted other countries who have had religious freedom problems in dealing with the coronavirus pandemic, including in China, where the virus originated. According to USCIRF, reports indicated that Chinese authorities forced Uighurs, a Muslim minority that has been forced into concentration camps since 2017, to work in factories to make up for the lack of workers during the country’s coronavirus quarantine. Reports also indicated that some Uighur residents in the city of Ghulja had “limited access to food and local officials have demanded payments in order to bring supplies,” USCIRF noted. In South Korea, the Shincheonji Church of Jesus, a fringe Christian group that reported already facing “hostility” from mainline Protestants before the pandemic, faced additional pressures and harassment from the government and citizens after a 61-year-old female member of the church - known as Patient 31 - attended a church service with a fever before being diagnosed with coronavirus, and thus spreading the infection to thousands of others. “The Shincheonji church has faced considerable criticism and even harassment from the South Korean government and society. Although some government measures appeared to be driven by legitimate public health concerns, others appeared to exaggerate the church’s role in the outbreak,” USCIRF reported, adding that members of the church have faced “discrimination at work and spousal abuse because of their affiliation with the church.” Other countries in which coronavirus is reportedly impacting religious freedoms include Iran, Saudi Arabia, Georgia, Italy and the Vatican (for government-mandated cancellation of religious services), the United Arab Emirates, Georgia, and Tajikistan.
