San Diego Police leaders defend use of controversial neck restraint

The technique applies pressure to the blood vessels on the side of the neck, until the person loses consciousness.The police department’s review last September revealed that the carotid restraint was used 58 percent of the time on subjects who were actively resisting and 28 percent in situations that also involved alcohol or narcotics. The carotid restraint was applied on African America subjects in 25 percent of the incidents. African Americans are 6 and a half percent of the city’s population.Community members have expressed reservations about the safety of the hold and whether the restraint could lead to death.  The department said it did not know of any incidents that resulted in death or significant injury.The police department said based on its review, it will continue to use the carotid restraint, although it will make some policy changes to sure the practice is safe. Those revisions include an annual review of the use of force, more frequent police training on the neck hold, taking subjects to whom the restraint was applied to a hospital for a medical evaluation and banning the use of the tactic on high risk individuals such as the elderly, those who are st obviously juveniles and pregnant women.The carotid restraint puts pressure on each side of the suspect’s neck, as shown in the photo below.

New Directorate at Hanscom AFB Underscores Regions Technological Edge Officials Say

first_img Dan Cohen AUTHOR Hanscom Air Force Base, Mass., will become the home of a new directorate that allows senior military leaders to communicate with the nation’s nuclear forces, adding more than 40 positions at the Boston-area installation and 40 more with local contractors.The Nuclear Command, Control and Communications (NC3) Integration Directorate and Program Executive Officer also brings a third high-ranking program executive officer to Hanscom. The move reflects “the importance of the base’s steadily growing mission and validates the unmatched technological expertise at Hanscom and throughout the surrounding region,” according to an announcement from the Massachusetts Military Asset and Security Strategy Task Force and the state’s congressional delegation.The directorate will not house actual weapons.Gov. Charlie Baker (R), the congressional delegation and members of the Task Force urged Air Force Secretary Deborah Lee James to consider Hanscom as the location for the new directorate when she visited the base last year.“This decision demonstrates the commonwealth’s many strengths and in coordination with our federal delegation, the overwhelming support and recognition for the role our military facilities, service members and their families play in Massachusetts,” Baker said.The importance of the region’s highly educated workforce was further reinforced last month when DOD announced it would invest hundreds of millions of dollars to upgrade MIT’s Lincoln Labs at Hanscom, said Rep. Niki Tsongas (D).“Now, the establishment of the NC3 Directorate at Hanscom is even further evidence that the military, at its top levels, recognizes and appreciates what Hanscom and the commonwealth have to offer: unmatched capabilities and benefits for our men and women in uniform that keep our military on the cutting edge of technical innovation,” Tsongas said.“By choosing Hanscom for this highly technical directorate, the DOD is solidifying its commitment to seeing Hanscom’s mission continue to grow, and ensuring that this base will continue to be an economic driver and job creator for years to come,” she stated.last_img read more

Sensex Soars 250 Points on RBI Rate Cut Hopes

first_imgThe S&P BSE Sensex rose nearly 250 points on Monday after a slew of positive data raised expectations over interest rate cut by the Reserve Bank of India (RBI) as early as this month.The Sensex ended at 25,856 points, up 246 points, or 0.96%, while the 50-share Nifty gained 82.95 points, or 1.06%, to close at 7,872 points.”Nifty is poised to make a dash towards the 8100 mark as the index has breached the neckline of an inverted bullish head and shoulder pattern indicating that the markets would surge higher,” said Amar Ambani, Head of Research, IIFL.While 29 out of 30 Sensex companies ended in green, metal index was the top gainer among sectoral indices.Earlier in the day, official data showed that the wholesale price inflation (WPI) declined further to minus 4.9% in August, reaching the lowest level since 2005. The WPI has been in negative territory for the past ten months.”The WPI rate may not have as much of a bearing on policymaking as the CPI rate, but the fact that it has plummeted again is unlikely to be ignored. This strengthens our view that interest rates will be cut at the RBI’s policy meeting later this month,” said Capital Economics in a note.The RBI’s next bi-monthly monetary policy review is scheduled on 29 September and the bank is widely expected to cut lending rates amid falling inflation rate.”We are maintaining our view that the RBI will cut the repo rate by another 25bp to 7.00% at its next policy meeting on 29th September before the easing cycle concludes,” said Capital Economics.Stock markets are also buoyed by a positive industrial activity data for July released on Friday after trading hours. The Index of Industrial Production (IIP) rose to 4.2%.”RBI will take a considered call on the issue. There is no divergence in perception. The government and RBI are working together. Taking into account the overall factors, RBI will take a considered call,” Economic Affairs Secretary Shaktikanta Das, told The Economic Times.Indian markets shrugged off weakness in equities in other major Asian countries. While China’s Shanghai Composite closed 2.6% lower at 3,114 points, Japan’s Nikkei ended at 17,965, down 299 points.Rate sensitive stocks like banking and real estate rose sharply. Banking stocks Axis Bank, ICICI Bank, HDFC Bank and SBI ended with a gain of 1 to 3%, while realty stocks India Bulls Realty, Sobha Realty and HDIL also ended higher. Metal stocks Vedanta, Hindalco and Tata Steel ended the session gaining 2 to 4%. IT stocks rose in anticipation of interest rate hike by the US Fed this week. Wipro gained nearly 2.5% to close at Rs 570.75. A rate hike by the US Federal Reserve is expected to further strengthen the US dollar, which could result in a revenue increase for Indian IT firms in rupee terms.last_img read more

Church World Service hosts Ration Challenge around World Refugee Day

Trina Bose North didn’t have a lot of ingredients to work with for a recent dinner party: lentils, chickpeas, rice, flour, a couple of spices and some sugar.But things turned out all right. She and her guests made garlicky flatbread, lentils on rice and chickpeas fixed two ways.There was even dessert.Her foodie husband borrowed a tip from some vegan friends and combined the sugar with leftover water from the chickpeas to make meringue cookies.The meal might not make it onto Pinterest or the pages of “Martha Stewart Living,” but it was filling, said Bose North, pastor of Crown Heights United Methodist Church in Oklahoma City.Bose North and her friends are among more than 14,000 Americans participating in the Ration Challenge for the first time this year — many, this week around World Refugee Day (June 20).The Rev. Trina Bose North, right, talks with refugee congregants about their experiences at Crown Heights United Methodist Church in Oklahoma City on June 2, 2019. Photo courtesy of Trina Bose NorthThe global challenge — organized in the United States by Church World Service — asks participants to live for a week on the same food rations people receive at refugee camps. The idea is to raise awareness for the challenges refugees face and funds to support them. Participants ask friends and others to sponsor them by donating to the cause.It also is a way to show support for refugees at a time when the U.S. refugee program is struggling. President Trump has set refugee admissions to the country at historic lows, said Mary Elizabeth Margolis, director of communications for the Immigration and Refugee Program at CWS.Many people feel there isn’t much they can do to help, Margolis said. This is one thing they can do.“It’s a way to show support in your communities and to start conversations and also to really make a difference by raising a couple of hundred dollars,” Margolis said. “If we all do that, it can have a huge impact.”The Ration Challenge began in 2014 when co-founders Kaz McGrath and Ben Littlejohn visited a refugee camp on the Thai-Myanmar border through their work for Act for Peace, the international aid agency of the National Council of Churches in Australia. There, McGrath and Littlejohn met with refugees and saw the sparse rations they receive.Sample contents of a Ration Challenge refugee box. Photo courtesy of Ration ChallengeFor a week, they decided to live on the same food to better understand the experience of living in a refugee camp.Since then, more than 40,000 people in Australia and New Zealand have joined Act for Peace’s annual Ration Challenge, raising more than $7 million to support refugees.CWS — one of nine agencies authorized to resettle refugees in the U.S. — was anticipating as many as 8,000 Americans might sign up for the challenge in its first year stateside, according to Margolis. Already, more than 14,000 have signed up from all 50 states, donating more than $264,000 as of Monday (June 17).About $2 million has been raised so far this year by the challenge.So many Americans registered to take part that CWS ran out of ration packs to send participants. The organization posted a list of what’s included in the challenge online so others can do it on their own.The packs for the challenge include the same rations received by a Syrian refugee living in a camp in Jordan: small bags of rice, chickpeas and lentils; a tin of sardines; flour; a can of beans; and a bottle of oil.Participants can earn additional ingredients for their meals by raising money for CWS and sharing about the challenge.The Syrian conflict, which started in March 2011, has led to hundreds of thousands of Syrians fleeing their country. The situation escalated in 2013 and again in 2015. It is estimated that over 1 million Syrian refugees have now fled to Jordan. Photo courtesy of Ration ChallengeThe funds raised by the Ration Challenge will provide food rations, medicine and education for Syrian refugees in Jordan.CWS also is among a number of faith-based organizations advocating on Capitol Hill for specific measures to help refugees.That includes the Grace Act, which would set the minimum number of refugees admitted to the U.S. each year at its historic average of 95,000. Current U.S. law allows the president to set the limit on how many refugees are admitted. Trump has set that number at just 30,000 for the current fiscal year, which ends in October.CWS also supports the No Ban Act, Margolis said, which would repeal and prevent efforts to ban Muslims, refugees and asylum-seekers from entering the country.“There’s a strong sense among the communities where we work that we have a responsibility to do something to respond to that and that protecting families is a fundamental value regardless of where those people come from or what their religious affiliation is,” Margolis said.Melanie Smith, left, and the Rev. Trina Bose North show off their flatbread-making abilities while participating in the Ration Challenge in Oklahoma City. Photo courtesy of Trina Bose NorthAt Crown Heights United Methodist Church, a team of coaches for the Ration Challenge has set up a temporary office and reaches out to participants throughout the week with tips and encouragement.Bose North spoke during a recent service at the church about her experience taking the challenge. Members of several refugee families who attend Crown Heights shared their stories as well.For the pastor, taking the Ration Challenge is one small way she can live out her Christian beliefs.“The call on all of us is to serve the least and the lonely among us, and refugees are some of the world’s neglected and forgotten people. To raise awareness, to provide help for refugees is absolutely what I’m called to do as Christian,” Bose North said.The challenge forced her to think of others’ experiences — so drastically unlike her own — in a way that was different from reading about the refugee crisis or seeing images in the news, she said.“You can read it, and that gets into your head, and you can write a check, and that affects you on a different level, but, man, to really experience it,” she said. “There’s something to be said about the experiential piece of this.” TagsChurch World Service CWS homepage featured Ration Challenge refugees World Refugee Day,You may also likecenter_img As Amazon burns, Vatican prepares for summit on region’s faith and sustainabilit … August 30, 2019 Catholicism By: Emily McFarlan Miller emmillerwrites Share This!

NYCArea Estate of 1st US SelfMade Woman Millionaire Sold

first_imgIRVINGTON, N.Y. (AP) — The New York estate built a century ago by a daughter of slaves who made her fortune selling hair care products for Black women has been purchased by an organization founded by the owner of Essence magazine.The National Trust for Historic Preservation announced Thursday that Madam C.J. Walker’s century-old Italianate villa-style mansion in New York City’s northern suburbs was recently bought by the New Voices Foundation, started by Richelieu Dennis, founder of a skin and hair care products company. A purchase price wasn’t released.This Oct. 19, 1998 file photo shows the Villa Lewaro, century-old Italianate-style mansion that was the home of Madam C.J. Walker, a black entrepreneur considered to be the nation’s first self-made female millionaire, in Irvington, N.Y. (AP Photo/Ed Bailey, File)Walker was born Sarah Breedlove in Louisiana in 1867 to former slaves. After marrying St. Louis newspaperman Charles Joseph Walker, she changed her name to Madam C.J. Walker and began selling her own hair care and beauty products made for Black women, a venture that made her wealthy as her name became known across the U.S., Central America and the Caribbean.Walker is considered the first self-made female millionaire in the United States.She followed her daughter, Lelia Walker Robinson, to Harlem in 1916. Two years later Walker built Villa Lewaro in Irvington, on the Hudson River in Westchester County. By the time she died of a kidney ailment there in 1919, her 34-room mansion had become a gathering place for leaders of the Harlem Renaissance, including W.E.B. Du Bois and Langston Hughes.Dennis, a Liberian immigrant, started Sundial brands in 1992 with his mother, making products based on African healing traditions passed down by his grandmother. He acquired the Walker brand in 2013 and relaunched it in 2016 as Sephora, and purchased Essence from Time Inc. earlier this year.Dennis’ New Voices Foundation, an organization that aids women of color entrepreneurs, will renovate and operate the former Walker estate, he said.“It is a place where — against all odds — dreams were formed, visions were realized and entrepreneurs were born, and we look forward to returning its use to support that mission,” Dennis said in a statement.Dennis’ foundation bought the property in mid-September.Villa Lewaro’s name was taken from the first two letters of each word in Walker’s daughter’s name. The home was designed by Vertner Woodson Tandy, the first licensed Black architect in New York state. Built on the heights overlooking the Hudson’s east bank, the mansion stood out even in an area dotted with estates owned by such wealthy whites as the Rockefellers.Walker’s daughter, who changed her name to A’Lelia, left the estate to the NAACP after she died 1931. The organization, struggling financially during the early years of the Great Depression, sold the property immediately after acquiring it. It had several owners over the next few decades before investment banker Harold E. Doley Jr. and his wife, Helena, bought the property in 1993.The home was named a National Treasure by the Washington, D.C.-based National Trust in 2014. It’s now among a growing number of historically Black properties being protected as part of the organization’s Cultural Heritage Action Fund, started last year to help ensure historical sites important to African-American history are no longer endangered.___This story has been corrected to fix estate ownership to organization founded by magazine owner instead of magazine owner and his family.last_img read more

Chain letters reveal surprising circulation patterns

first_img Explore further This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The chain e-mail originated sometime in 2002, and claimed to be a petition to organize opposition to the impending US-Iraq war. Tens of thousands of people signed their names to several hundred copies of the petition, with some copies appearing on Web archives. Like most Internet chain letters, the petition had its origins in a hoax, but its widespread dissemination is one of the few instances of a single piece of traceable information spreading on a global scale.“Given the many ways in which information, news, and new ideas are constantly spreading through our social networks, it’s surprising how difficult it is to collect data on the ways in which this spreading happens,” researchers David Liben-Nowell and Jon Kleinberg told PhysOrg.com. “Data from chain-letter petitions lets us look at processes that are otherwise essentially invisible, and begin to formulate theories for the patterns we observe.”Liben-Nowell and Kleinberg are computer scientists from Carleton College and Cornell University, respectively. The duo used online search engines to collect copies of the signed petitions that were posted on numerous Web sites. When they analyzed the 20,000 names on the 637 lists they found, and removed various “mutations,” they discovered some surprising patterns. Contrary to predictions that large-scale information spreads exponentially, like an explosive epidemic, the researchers found that the letter did not reach a large number of individuals in a few steps. Rather, it took hundreds of steps of people forwarding the e-mail on to reach the 20,000 who signed the found copies. As the researchers explain, this pattern suggests that the mechanics of a single piece of information spreading on a global scale is more complex than originally thought. Some of their results, which appear in a recent issue of the Proceedings of the National Academy of Sciences, reveal that people who forwarded the letter generally forwarded it to large numbers of other individuals. By contrast, most senders (94%) produced just one “daughter” that signed the letter. In other words, it seemed that most people ignored the e-mail. Citation: Chain letters reveal surprising circulation patterns (2008, April 10) retrieved 18 August 2019 from https://phys.org/news/2008-04-chain-letters-reveal-circulation-patterns.html A chain letter hoax that fooled thousands of people may help computer scientists understand how information spreads on a global scale. The final result was a “tree” of nodes and connections that was long and thin, not one that funneled out as in the case of rapidly spreading information. Gossip in smaller communities may fan out quickly, but – as the new study shows – such a pattern changes with scale. This large-scale spreading of information is a rare case, since most circulated e-mail messages never reach such a large number of recipients.“A natural assumption going into this study was that information would spread explosively, reaching many people in only a few steps,” said Liben-Nowell and Kleinberg. “Instead, a much more complex picture emerges, with the chain letter following longer, narrower paths. After this initial surprise, we eventually found possible ways to reconcile the deep, narrow structures we observed with the facts we knew about human social networks.”A couple things that might explain the pattern include individuals “forwarding” the petition to the same group of e-mail addresses copied on the e-mail they received (“replying to all”). Individuals who received the petition more than once typically only signed one of them, leaving others as dead ends. Also, individuals in the same network might have tried to all sign the same petition, and keep forwarding it to each other rather then adding their names to different lists – which produces the observed “single daughter” characteristic.Understanding how a single piece of information spreads on a large scale may have applications in a variety of areas, such as word-of-mouth marketing and investigating the spreading of technological innovations, news, and opinions. Contrary to spreading explosively, information traveling on large scales seems to be quite fragile, with many opportunities for getting lost. The pattern might hold true for different kinds of information spreading, as well.“We expect this kind of pattern would show up in certain other settings, but it’s an open question how general it is,” the researchers said. “For example, the other large-scale chain-letter for which we have data – a petition to support funding of National Public Radio – exhibits a spreading pattern that looks very similar. It’s natural to believe that jokes and news clippings on the Internet may well spread in similar ways, though there certainly could be differences in spreading patterns between information that is politically charged and information that is free of controversy.“Once we look more generally – say, at the spread of new technologies or new products by word-of-mouth, or the rise in name recognition of new celebrities or new political figures – it’s a fascinating open question to consider how diverse the different spreading patterns might be. But we expect that in all these cases, the spreading will likely have a structure that is more complex than simple models have suggested.” More information: Liben-Nowell, David, and Kleinberg, Jon. “Tracing information flow on a global scale using Internet chain-letter data.” Proceedings of the National Academy of Sciences, March 25, 2008, vol. 105, no. 12. 4633-4638.Copyright 2008 PhysOrg.com.

Jupiter has lost one of its cloud stripes

first_img Explore further (PhysOrg.com) — New photographs of the gas giant Jupiter, the first taken on May 9, show the massive reddish band of clouds known as the Southern Equatorial Belt in the planet’s southern hemisphere has disappeared from view. The South Equatorial Belt (SEB) has faded away leaving just the north belt (NEB) viewable in small telescopes. Image credit: Anthony Wesley This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Citation: Jupiter has lost one of its cloud stripes (2010, May 14) retrieved 18 August 2019 from https://phys.org/news/2010-05-jupiter-lost-cloud-stripes.html © 2010 PhysOrg.com Aus amateur tells of ‘one in a million’ Jupiter spot The first photographs were taken by a noted Australian amateur astronomer, Anthony Wesley from Murrumbateman in New South Wales, using a 14.5 inch telescope. Wesley said he had been eagerly waiting to take photographs after Jupiter disappeared behind the sun and out of view for three months. In mid 2009 it was clear to Jupiter watchers the cloud band, which encircles the planet, was beginning to enter a new fading cycle. Wesley, an enthusiastic Jupiter observer, said the exact time the cloud belt will revive is unknown, but it fades every three to 15 years. Previous fading cycles have been characterized by violent and dramatic storms in the southern equatorial latitudes. The Northern and Southern Equatorial belts are composed of ammonia ice with phosphorus and some sulfur.It is not known why the belt periodically disappears, but it may be that it sinks lower if it cools, and then the view of it is obscured by clouds pouring in over the top of it. The clouds on Jupiter are tens of thousands of kilometers deep. Wesley said the phenomenon could be linked to storm activity that preceded the change.Wesley said Jupiter, the largest planet in the solar system, is fascinating to observe and photograph because the internal heat deep within the atmosphere makes it so dynamic and dramatic, and it can look different even from one day to the next. Watch Jupiter rotate and its cloud belts move with the winds. The time-lapse video was made using images shot during Voyager 1’s flyby of the planet in 1979. The most dramatic feature on Jupiter is the Great Red Spot, which now stands out more than usual since it is on the edge of the Southern Equatorial Belt, which has now faded from view. The Great Red Spot is a huge storm twice the size of Earth that has raged for at least three centuries, although astronomers said last year it appears to be shrinking. The photographs taken by Wesley have been released by The Planetary Society in California, and are also available on Wesley’s own website. In July last year Wesley was first to notice a dark blemish on Jupiter, probably caused by a comet. It is possible to see the features of Jupiter even with quite a modest telescope.last_img read more

Study shows differences in brain activity of humans and macaques engaged in

first_img Pictured are the increases (orange-yellow) and decreases (blue) of neural activity in the brains of humans and macaques while performing the same attention task as measured by functional magnetic resonance imaging. In this study, the researchers found that the attention networks in humans fundamentally differ from those of macaques in three ways: the networks contain more areas, more information is shared between brain hemispheres, and humans possess an entire attention control network that is missing from macaques. The results suggest that the attention network has evolved to support uniquely human cognitive functions.

Journal information: Proceedings of the National Academy of Sciences Barbary macaques. Credit: Wikipedia/Flickr/Karyn Sig At least two regions of the brain decide what we perceive As part of the experiment, one assumption has been that the macaque brain is likely very similar to the brain early humans had when the last common ancestors of the two species branched off in different directions. This means that the team was free to suggest that the differences they saw in the brain scans, likely indicate evolutionary changes that have occurred to our brains over the past 25 million years. Explore furthercenter_img © 2015 Phys.org In trying to better understand how it is the human brain works, scientists sometimes use macaques as stand-ins—that is because sometimes the experiments conducted cannot be performed on humans. One problem with this approach is that it is still not clear just how alike the brains of humans and macaques actually are. To learn more, the group conducted experiments that looked into which parts of the brain are active in both species engaged in the same task.The experiments consisted of putting eight human beings and two macaques in an fMRI machine while they engaged in the same task and watching which parts of the brain lit up. The task consisted of staring at a single point on a computer screen while objects were displayed near the single point and pressing a button when a certain image appeared. All the volunteers were trained on the task prior to being put into the fMRI machine.In analyzing the results the researchers discovered that the temporoparietal junction was much more active in the humans—they also noted that some other areas of the brain were more active as well. Furthermore, they discovered that there was more communication going on between the two brain hemispheres. In looking at all the differences taken together, the researchers conclude that humans have a more advanced attention control network, which they note, makes sense, because we humans need to filter information more than macaques—the monkeys, presumably, must be able to react to dangerous situations much more quickly than us. (Phys.org)—A group of researchers with affiliations to several institutions in the U.S. has identified some of the ways the human brain differs in the way it focuses on a task as compared to macaques. In their paper published in Proceedings of the National Academy of Sciences, the researchers detail experiments they carried out with both humans and macaques using fMRI scans.

Patel, Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.1420395112AbstractMacaques are often used as a model system for invasive investigations of the neural substrates of cognition. However, 25 million years of evolution separate humans and macaques from their last common ancestor, and this has likely substantially impacted the function of the cortical networks underlying cognitive processes, such as attention. We examined the homology of frontoparietal networks underlying attention by comparing functional MRI data from macaques and humans performing the same visual search task. Although there are broad similarities, we found fundamental differences between the species. First, humans have more dorsal attention network areas than macaques, indicating that in the course of evolution the human attention system has expanded compared with macaques. Second, potentially homologous areas in the dorsal attention network have markedly different biases toward representing the contralateral hemifield, indicating that the underlying neural architecture of these areas may differ in the most basic of properties, such as receptive field distribution. Third, despite clear evidence of the temporoparietal junction node of the ventral attention network in humans as elicited by this visual search task, we did not find functional evidence of a temporoparietal junction in macaques. None of these differences were the result of differences in training, experimental power, or anatomical variability between the two species. The results of this study indicate that macaque data should be applied to human models of cognition cautiously, and demonstrate how evolution may shape cortical networks.last_img read more
