Economists Buyers face tougher housing market in 2019

first_imgAmericans’ path to homeownership is likely to get more expensive this year, even as a severe shortage of homes for sale shows signs of easing.Mortgage rates, which climbed through much of last year, will continue to rise in 2019, driving up homebuyers’ borrowing costs and shutting others out of the market entirely. The projected result: a cooling housing market and falling home sales nationally.“On the whole, it’s going to be more expensive for buyers next year, despite the fact that they’ll have more options,” said Danielle Hale, chief economist at Realtor.com.The U.S housing market stalled in 2018 after a long period during which price increases outpaced income growth. That had been offset by historically low mortgage rates, until rates began rising steadily a year ago.While still low by historical standards, the average rate on a 30-year home loan was 4.55 per cent last week, according to mortgage buyer Freddie Mac. That’s up from 3.99 per cent a year earlier.Realtor.com and Redfin forecast the rate on a 30-year, fixed-rate mortgage will rise to 5.5 per cent by the end of 2019. Zillow expects rates will reach 5.8 per cent. That would be rates’ highest level since the last recession.A mere extra half percentage point can boost monthly payments and add tens of thousands of dollars in interest over the life of the typical 30-year loan.“Rising mortgage rates will take a bite out of affordability on top of an already supply- constrained and high-priced housing market,” Trulia senior economist Cheryl Young wrote in her forecast.As mortgage rates increase, so does the pressure on would-be buyers to lock in a rate and close a deal.Nate Vogel, a homebuyer in the Denver suburb of Lafayette, has felt some of that pressure after about a year looking for a home without success.Because of the limited number of homes for sale, especially under $500,000, the software engineering manager recently decided to look at homes at the top of his budget, $650,000. But that could be a problem if mortgage rates continue climbing.“If that interest rate goes up another per cent, that would make things much more uncomfortable,” said Vogel, 37. “At this point, no matter what house I buy, I’m sure the interest rate will probably be higher and the payment will be more.”Higher mortgage rates have already started dampening home sales. As of November, sales of previously occupied U.S. homes were down 7 per cent from a year earlier, the steepest decline since May 2011, when the housing market had yet to bounce back from the bust.Realtor.com predicts U.S. home sales will fall another 2 per cent in 2019.It’s not all bad news for would-be buyers, though. Economists project home prices will rise more slowly in 2019. Zillow’s forecast calls for prices to increase nationally by about 3.8 per cent. Realtor.com has them rising at just 2.2 per cent.Another plus for buyers: The number of homes on the market is expected to continue rising, albeit from historic low levels. The inventory of U.S. homes for sale was up 4.2 per cent as of November to 1.74 million units.Alex Veiga, The Associated Presslast_img read more

Arsenal lean on Alexandre Lacazette Aubameyang to save their season

first_imgLondon: Arsenal’s collapse at the business end of the Premier League season means the success or failure of Unai Emery’s first campaign now solely depends on lifting the Europa League and as a result sealing Champions League football. The Gunners travel to Emery’s old club Valencia on Thursday defending a 3-1 semi-final, first leg lead given to them by star strikers Alexandre Lacazette and Pierre-Emerick Aubameyang at the Emirates last week. Arsenal’s awful record on the road this season will give the Spanish side plenty of encouragement that they can overturn a two-goal deficit. Emery’s men conceded three times in losing at Wolves and Leicester in their last two away league games and were also defeated at BATE Borisov and Rennes before turning Europa League ties around at the Emirates. Attack may therefore be the visitors’ best form of defence in the cauldron of the Mestalla and Arsenal are at least getting what they paid for from Lacazette and Aubameyang. “We played against two strikers that are very good which is why they cost the millions that they did,” said Valencia coach Marcelino Garcia Toral. “With the slightest error they punish you.” Arsenal have taken one point from their last four Premier League games to realistically end their chances of a top-four finish and the first leg against Valencia could easily have gone the same way as Marcelino’s men scored an early away goal and led the Gunners to a merry dance for the first 20 minutes. However, one moment of magic turned the tie as Lacazette played in Aubameyang, who paused, left Neto, Ezequiel Garay and Facundo Roncaglia on the floor before squaring for his strike partner to roll into an empty net. Lacazette added his second eight minutes later and Aubameyang’s late strike gave Arsenal the two-goal cushion they may well need. The Londoners’ first season without Arsene Wenger for 22 years has been dogged by many of the same defensive problems suffered by the Frenchman towards the end of his reign. But Wenger’s final two big signings have come good as club record fees were paid for Lacazette in the summer of 2017 and Aubameyang in January 2018. After a difficult first six months in England, many thought Aubameyang’s arrival was ominous for Lacazette’s longevity at the club, but the two have formed a fine partnership on and off the field. Only Liverpool’s Mohamed Salah has scored more Premier League goals than Aubameyang’s 20, but it is Lacazette who won the club’s player of the year prize for his all round contribution with 18 goals and 12 assists.last_img read more

Beyond communal lines

first_imgThe General Election this time has been marked by a significant amount of violence in the run-up to the polls in several parts of the country. The bitterness amongst the contesting parties in states like West Bengal, Andhra Pradesh, Uttar Pradesh and Maharashtra precipitated clashes between rival workers testing the efficacy and impartiality of the local police. The institution of the State Electoral Officer did not seem to be strong enough in monitoring the performance of the district police officials and taking action against those who showed serious dereliction of duty. Violence around polling booths is a negation of democratic rights of the voters and by now India should have been able to practice zero tolerance towards this malaise. It is high time a commission examined the ways and means of ensuring peace during elections and defined specific policy measures in this regard for the future. It is highly regrettable that the largest democracy in the world cannot liberate the election process of street-level violence. Clearly, in the federal scheme of things, it is the state police chief who has to take direct responsibility for it and demonstrate his or her apolitical credentials while handling law and order during elections with an iron fist. There should be no delay in the implementation of the Supreme Court order issued last year against the practice of appointing officiating DGPs – that also clearly laid down that the UPSC will draw up a panel of three names in consultation with the state government and that the state government will make one of them the DGP of the state on the basis of merit-cum-seniority. This is the single most important Police reform that the Centre must put in place at once. Another area of political violence that showed up during and outside of elections, concerns the injurious fallout from public speeches that tended to instigate caste, communal or regional conflicts. Pungent wit and some name-calling without violating the law of defamation could be a legit part of electioneering but deliberately indulging in identity politics and questioning the symbols of nationalism became much too obvious in the poll fray this time. India is vulnerable to communal and caste tensions and freedom of expression cannot be allowed to cross the legal limits put on it by the Criminal Law Amendment Act of 1972 that created Sections 153A & 153B to define cognizable and non-bailable offences pertaining to sectarian speeches. The police machinery of the districts has to be strengthened a great deal with manpower and technological equipment to enable it to handle this rampant criminality committed by the people in public life today. Follow up on the blatant violations of law noticed in this General Election should continue even after the poll process is over. The most dangerous form of political violence that is steadily permeating our nation, however, is the rise of new terror emanating from faith-based motivation. Terrorism by definition is the resort to ‘covert violence for a perceived political cause’. In the absence of such a ’cause’, the violence will just be sheer criminality; and terrorism is not that, certainly. A cause demands ‘commitment’ which in turn is rooted in ‘motivation’. India has seen diverse motivations behind terror movements and insurgencies – ‘ideological’ that sustained Maoism or assertion of ‘ethnic identity’ that was the case with North-East insurgent groups – but the new global terror that is now afflicting the world and becoming a prime security threat to India is a class apart since it is linked to the call of ‘defence of Islam’ or Jihad. This is an outcome of the complications connected with the ‘war on terror’ launched against the Islamic radicals by the US-led West post 9/11 on the one hand and the cross border terrorism started by Pakistan to settle scores with India using India- specific terror outfits under the ISI control, on the other. Developments in recent times have made Pakistan the world repository of Islamic militancy and the agencies in that country are now manoeuvring the entire spectrum of militants from Al Qaeda-Taliban combine and ISIS at one end to Lashkar-e-Taiba and Hizbul Mujahideen at the other. The keenness of the US to work for the withdrawal of American troops from Syria and Afghanistan has given a lot of residual advantage to Pakistan in terms of its plans to use Islamic militants as a strategic resource for furthering its foreign policy objectives. India has much to feel concerned about the way the US was relying on Pakistan to reach a settlement with the Taliban. While this is the scene in Afghanistan, the recent terror bombings against Christians and Western tourists in and around Colombo have been claimed by ISIS. What is more significant, the local radical outfit, the National Towheed Jamaat, complicit in this covert offensive in Sri Lanka is found to have links with Pakistan and South India. It is already known that Al Qaeda in Indian Subcontinent (AQIS) operating out of Pakistan with patronage from ISI has the avowed aim of establishing Islamic State in Pakistan, India, Bangladesh and Myanmar. India, unlike the US, is directly in the arc of Islamic militancy and needs to strategise for national security against this new threat of faith-based terror. It is extremely disquieting that political discourse in India – and this became sharper in the election campaign – has tended to drag Pakistan into the discussions on minorities here. This trend has started from Jammu and Kashmir where the regional parties have openly advocated a communally-based ‘solution’ by talking of the Valley and not about the integral state of J&K that is home to many religions. They have strengthened the hands of Pakistan which finds it convenient to project Kashmir as a Muslim issue and create a communal divide in the domestic politics of India. The same effect is produced by some opposition leaders at the national level who criticised the ‘muscular’ policy of the Modi government towards Pakistan but maintained deliberate silence on the infiltration of terrorists by Pakistan’s ISI across the LOC to create violence in the state. The campaign for General Election this time has deepened the communal antagonism on majority-minority line and left the country vulnerable to Pak machinations to generate militancy as a byproduct of communal disharmony. In the initial decades after Independence, India witnessed communal riots primarily because of the legacy of Partition but these subsided as the democratic processes took firm root and equality of rights played out for everybody. The rise of new global terror that invokes the cause of Islam has made it possible – particularly because of the mischief of Pak agencies – for radicalisation to seep into India, howsoever small may be its spread in the country so far. The events at Colombo come as a wake-up call for our security set-up. Various communities of India at the level of average citizens want to lead a peaceful life and make use of whatever opportunities of economic advancement that would become available to them. It should not be difficult to achieve a convergence amongst all communities on the external threats to national security if the leaders of the communities did not seek political power by dividing the people. Our laws and security policy should provide for quick punishment for those who tried to gain from the advocacy of violence in course of projection of religion into politics. Our ruling dispensation should be upfront about it – this seems to be the major learning from the 2019 national election. (The writer is a former Director of Intelligence Bureau.

An Inconsistent Strike Zone Hurt Both Teams in Game 3

CHICAGO — The Cleveland Indians won a 1-0 nail-biter on Friday night in Game 3 of the World Series. Two number-three starters succeeded in shutting down two strong offenses, allowing the game to come down to the final at-bat. But while the relievers were overpowering as usual, the most significant influence on this game wasn’t the wind, a single Indians hitter or managerial cleverness, but a seemingly inconsistent strike zone.Home plate umpire John Hirschbeck has a reputation for calling balls and strikes erratically, and that was on full display last night, creating shifting strike-zone boundaries that bedeviled both offenses.1A rough look at the strike zone plots for each team showed about 10 calls helping the Cubs, and seven helping the Indians. Data from PitchF/X needed for a quantitative comparison was not available at time of publication. For the Indians, Josh Tomlin turned in an unexpectedly solid line, allowing only two hits. At times, Tomlin was burned by bad calls, leading, for example, to a fourth-inning walk by Kris Bryant. But when the strike zone is called inconsistently, hitters tend to strike out more often and make weaker contact. That’s because pitchers can choose to target inconsistently called areas of the zone when it benefits them, while hitters can only decide whether to swing or not at what’s offered. When they’re uncertain, batters often opt to swing at pitches outside the zone, resulting in glancing contact and easy outs.Chicago Cubs starter Kyle Hendricks, who usually gets favorable strike calls due to his impeccable command, struggled mightily in allowing six hits and two walks in only 4.2 innings. The shifting zone did aid him in racking up six strikeouts, above what you’d expect based on his regular-season stats.Even as the inconsistent strike zone helped the pitchers, neither was overpowering. And with bullpens fresh after the day off, both starters were pulled before the 6th inning with the score 0-0, an event that has never happened before in MLB postseason history. That handed the game to the relievers, including an early appearance from Andrew Miller. They were as commanding as expected, except for one lapse by the Cubs’ Carl Edwards Jr., who allowed Coco Crisp to single in the lone run of the night.The Cubs came close to evening the score in the bottom of the ninth. With two runners in scoring position and two outs, Chicago dynamo Javy Báez was up to bat against Cleveland closer Cody Allen. He struck out whiffing to end the threat, leaving the Indians up 2-1 in the Series.The outlook for the Cubs is worrisome going forward: Their series win probability by Elo is down to only 37 percent.2For reference, that’s the same probability Elo gave the Indians before the World Series began. In his last start, Corey Kluber looked invincible, and the Cubs will have to face him in Games 4 and 7 of this Series (if it goes that far). That means they will need to pull off at least one upset against the 2014 AL Cy Young winner to clinch the series. While such a feat appears difficult, the Cubs managed an even more surprising performance against Clayton Kershaw in the NLCS, so it’s certainly possible. Nobody said ending a 108-year title drought would be easy.CORRECTION (Oct. 29, 12:05 p.m.): An earlier version of this article incorrectly described Corey Kluber. He was the 2014 AL Cy Young winner; he is not the reigning winner. read more

Ohio State Is Always Facing High Expectations — Scandal Or Not

*In preseason polls since 1976-77 season for women’s basketball, 1961-62 for men’s basketball and 1950 for football.Source: College Poll Archive TexasFootball5275 The year was 1956. Ohio State’s college football program was ranked fifth in the annual Associated Press preseason college football poll and was coming off a season in which they had won all but two games. Expectations for a strong season were, no doubt, high.But head coach Woody Hayes was in hot water with the Big Ten for providing loans to his players, and after an investigation, the conference put the team on probation for one year and banned it from playing in that season’s Rose Bowl.Sixty-two years later, Ohio State is once again entering the season with a No. 5 preseason ranking, having won all but two games the previous season. Controversy blankets the campus once more: Head coach Urban Meyer has been suspended for the opening three games of the season after an investigation concluded that he had mishandled domestic assault allegations against former wide receivers coach Zach Smith.High expectations are nothing new in Columbus. For about as long as college football has been around, the Ohio State Buckeyes have been a force. In the annals of the sport’s history, only Michigan (943) — oh, the irony — and Notre Dame (906) have won more games than the Buckeyes (898).1Excluding Yale, which is not currently a Division I Football Bowl Subdivision team. Since the turn of the century, only Boise State, which has played in three non-Power-Five conferences over that stretch, has won more total games than Ohio’s flagship university.And that prodigious success isn’t lost on Associated Press voters.Ohio State has failed to make the poll just four times in the 69-year history of the poll, most recently in 1988. That was John Cooper’s first year at the helm after taking over for the fired Earle Bruce. Cooper wouldn’t miss another preseason poll. Hayes only missed out in 1966 and 1967, the lone instance of the team failing to crack the AP preseason poll in consecutive years.Which got us thinking: Does Ohio State dominate this poll more than any team in any sport dominates its preseason poll? AP voters produce a preseason, weekly and postseason poll for three college sports: football, men’s basketball and women’s basketball. In 1989, the polls expanded to a 25-team format, which remains the current standard.Across the three sports, only the Tennessee Volunteers women’s basketball program has been more of a mainstay on the preseason poll than the Ohio State football team, according to data from the website College Poll Archive. Tennessee has made the AP preseason poll 98 percent of the time. It’s missed just once in the poll’s 42-year history — in 1976, the year the poll was introduced. Largely under their legendary coach, the late Pat Summitt, the Volunteers piled up eight national championships and 18 Final Four appearances, controlling the sport for decades before Connecticut assumed the mantle. 2Ohio StateFootball6594 RKTeamSportCountRate* 5USCFootball5884 3KentuckyMen’s basketball5088 9GeorgiaWomen’s basketball3276 4OklahomaFootball6087 Appearances 7Notre DameFootball5580 The preseason eliteTeams with the highest rate of appearances in AP Top 25 preseason polls in men’s or women’s basketball and college football 1TennesseeWomen’s basketball4198% 10AlabamaFootball5275 North CarolinaMen’s basketball4884 UCLAMen’s basketball4375 8TexasWomen’s basketball3379 Ohio State has at least five more appearances on the AP preseason poll than any team in any sport, having qualified in 94 percent of available seasons. Since 1989, Ohio State’s average ranking in the preseason AP poll is 10.3. And perhaps no team dominates the opening month of the season like Ohio State, which has gone 21-2 over the last six years in the month of September, winning by an average margin of more than 30 points per game. But preseason rankings aren’t always pinpoint precise: Ohio State typically underperforms relative to its lofty preseason ranking.AP preseason polls typically draw from blue-blood schools, so it’s no surprise that other well-heeled programs like the football teams at Oklahoma and USC and the men’s basketball team at Kentucky are among the most-ranked.But on the gridiron, no team is accustomed to high expectations like the Buckeyes. Columbus has produced the second-most first-round NFL draft picks all time, and the team is expected not only to win, but to dominate. In this weekend’s season opener against Oregon State, Ohio State opened as 38-point favorites, the most lopsided betting line of any opening-week contest for a ranked team. “A place like Ohio State, we’re expected to win every game we play,” Meyer has said. “There’s not many places like that.” Those are expectations that Meyer also noted aren’t always “easy to embrace.” But players and coaches alike should recognize that’s what they’ve signed up for in Columbus: a culture of on-field success, national title aspirations and a preseason ranking. read more

Mens soccer OSU earns draw over weekend against No 7 Indiana

With No. 7 Indiana coming to town, the Ohio State men’s soccer team looked to take down another Big Ten foe at Jesse Owens Memorial Stadium.Coming off a dominant 3-0 win over Oakland on Tuesday, the Buckeyes looked to ride momentum in hopes of improving their conference record of 2-3.OSU redshirt freshman goalkeeper Parker Siegfried (1) prepares to return the ball to midfield during the Buckeye’s game against Valparaiso on Sept. 21 at Jesse Owens Memorial Stadium. The Buckeyes won 4-1. Credit: Janaya Greene | Lantern PhotographerOhio State and Indiana played to a 2-2 draw on Saturday afternoon, with neither team able to find a game-winner through two overtime periods.“It could have gone either way,” OSU coach John Bluem said. “Earlier in the year we lost three games in sudden-death overtime. I think our guys were determined not to let that happen again.”The Buckeyes opened up the scoring early in the first period.In the 5th minute of play, junior forward Nate Kohl secured the ball in the box after a failed clearing attempt by the Indiana goalkeeper. Kohl deflected the ball off his chest then slid down to redirect it into the back of the net, giving the Buckeyes a 1-0 lead.For Kohl, it was his team-high fifth goal of the season.Indiana netted an equalizer in the 18th minute with a header by sophomore midfielder Jeremiah Gutjahr.However, it did not take long for the Buckeyes to answer back.In the 20th minute, Kohl worked a ball down the sideline. He slotted a pass through the middle in between a couple Hoosier defenders, finding senior midfielder Ben Fitzpatrick, who used a good first touch to get around his defender. He then fired it into the back of the net from 12 yards out, putting OSU back on top 2-1.“Me and Ben have worked on and off the ball together pretty well,” Kohl said. “I know how he plays and he knows how I play so it just keeps getting better. Its sad it took until the end of the season to start working, but I guess it’s as good a time as any.”Just as it seemed like the Buckeyes had the game in the bag, Indiana upped the tempo and started applying pressure deep in the offensive zone.With just seven minutes remaining in regulation, senior defender Billy McConnell deflected an Indiana shot inside the box that rolled just out of reach of OSU redshirt freshman goalkeeper Parker Siegfried to tie the game up at two.Neither of the two teams had many scoring opportunities in the two overtime periods, as the game ended in a tie.“When you let up an equalizing goal that late, your team could fold,” Bluem said. “For those last 27 minutes, our guys strapped them back up and fought hard to not allow that winning goal.”The Hoosiers outshot OSU 14-5, including an 8-1 advantage in the second period. Siegfried made five saves.The two teams seemed to have some bad blood, as things got chippy as time went on. Indiana accumulated a staggering 28 for calls, including four yellow cards for Indiana. OSU amassed 12 total fouls.“They were getting a little upset that they are the No. 7 team in the country and we were putting the pressure on them and taking the wind out of them,” Kohl said. “Things got a little chippy, but nothing we couldn’t handle.”Bluem said he was very proud of how his team played despite missing a few of their key guys to injuries.“We have a lot of talent sitting on our bench that can’t play,” Bluem said. “Yaw (Amankwa) couldn’t play today. Danny (Jensen) is out. (Marcus) McCrary is out. The guys that are being called upon in their place are really doing a great job.”Next up for the now 4-9-1 Buckeyes is a road contest against No. 4 Louisville on Tuesday at 7:30 p.m. read more

DeVier Posey to Verlon Reed Heres how to receive with ease

The Buckeye quarterback battle has dominated talk at the water cooler, but the biggest concern heading into spring might have been the lack of depth at wide receiver. With DeVier Posey suspended for the first five games of the season and the graduation of Dane Sanzenbacher, the Buckeyes lost virtually all meaningful experience at the position. The Buckeyes have a collection of young players who hope to fill the void, but their performances in the early parts of the spring were far from encouraging. “We got young guys at receiver and I thought they really came along this spring,” coach Jim Tressel said after the Spring Game on Saturday. “I think after about three practices we were thinking, ‘Oh my gosh, we might be in three (tight ends), a fullback and a tailback.’” But Posey took it upon himself to bring the younger guys along. “I think for me the biggest thing to get those guys to understand as far as leading by example is practicing hard every single day,” Posey said. “I want them to see how passionate I play, how the game is supposed to be played and how fast the game is supposed to be played so that they can learn from that.” Posey said the receivers needed some help getting accustomed to college football and the rigors of being a student-athlete. “They had some rough days,” Posey said. “They had some days they didn’t want to play football anymore, and they had some days where they looked like All-Americans and I felt like that was key to get those guys on a straight line and keep them consistent.” Posey’s example seemed to make a big difference. During the first two jersey scrimmages, Posey was the only receiver to reach the end zone, but Saturday’s Spring Game saw four new receivers cross the goal line. At 6-foot-5, 228 pounds, redshirt freshman T.Y. Williams is an imposing physical target. He’s had issues catching the ball in his brief time at Ohio State, but he led the team in receiving yards Saturday with three receptions for 83 yards, including a 68-yard touchdown catch from quarterback Taylor Graham. Sophomore Corey “Philly” Brown is the only receiver with legitimate game experience. Brown had eight receptions for 105 yards and a touchdown last year and is the leading candidate to replace Posey as the top wide receiver. He hauled in a 15-yard touchdown pass from Braxton Miller on Saturday. Tressel seemed prophetic after calling redshirt freshman Verlon Reed the “dark horse” before the Spring Game. Reed caught Saturday’s first touchdown pass, a 17-yard strike from Kenny Guiton. A quarterback in high school, Reed has caught the attention of his teammates with his play. “I think he’s stepped up,” offensive lineman Mike Brewster said. “I think he’s started to make a name for himself on the team.” Ryan Ross also caught a touchdown from Joe Bauserman. “I felt like a proud dad today watching three of them score touchdowns and making big plays,” Posey said. “To me, that shows their growth and that shows their maturity.” Posey said the success for the young receivers in the spring game will help their progression through the summer and fall camps. “It’s definitely a confidence booster,” Posey said of the receivers’ touchdowns. “I think that was Corey’s second time scoring at Ohio Stadium and it was Tyrone and Verlon’s first time. They’re happy, man, and I’m really excited for those guys.” But the young group still has a ways to go. Most of the receivers’ success came when the first-team defense watched from the sidelines. “(The receivers) need to have tremendous progress between now and September,” Tressel said. “But I think for all of our guys, receivers especially, with the youth of them, this spring was well-served.” Recruits Devin Smith and Evan Spencer will both join the receiver battle this summer and hope to help the offense deal with Posey’s absence. Posey, quarterback Terrelle Pryor, offensive lineman Mike Adams, running back Dan Herron and defensive lineman Solomon Thomas are suspended for the first five games of the 2011 season for selling memorabilia and receiving improper benefits. Tressel will join them for failing to report their violations. OSU has until July 5 to respond to the NCAA’s questions and will meet with the Committee on Infractions on Aug. 12. read more

Thibaut Courtois circumstances at Chelsea explained

first_imgBelgian journalist Kristof Terreur has given insight into Thibaut Courtois’ difficult circumstances at Chelsea after he was absent from training on MondayThe Belgian goalkeeper failed to report back for pre-season training at the club’s Cobham training base on Monday after Chelsea decided to put talks with Real Madrid on hold until they have found themselves a suitable replacement.Courtois, who has been away on holiday following his exploits at the World Cup for Belgium this summer, appears to be getting desperate to force through a move to Real after reportedly telling new Chelsea boss Maurizio Sarri that he intends to leave this summer.But with just two days remaining until the English transfer window closes, time is now very much against Courtois and the 26-year-old is now to be resorting to desperate measures to make his dream move a reality.“Chelsea are searching for a solution for this situation because they have already known for a while, since January when Courtois rejected a new contract offer, that he wasn’t going to sign a new deal,” explained Terreur, via Football365.“They know his personal situation with his kids living with his former partner in Madrid, him wanting to be closer to them and pursuing a challenge in Madrid too.Tammy Abraham, ChelseaChelsea hat-trick hero Tammy Abraham hopes for more Andrew Smyth – September 14, 2019 Tammy Abraham hopes this season will be his big breakthrough at Chelsea after firing his first hat-trick for the club in Saturday’s 5-2 win at Wolves.“His mind has never left Madrid after he spent three years on loan over there.

Bowie Man Indicted For Defrauding Veterans Administration

first_imgBy Mark F. Gray, Staff Writer, mgray@afro.comA Bowie man was indicted on 20 counts for defrauding the United States Department of Veterans Affairs (V.A.) of $300,000 by a federal grand jury for allegedly using his business to deceive a program for disabled military veterans on April 22.Francis Engles, 63, is alleged to have used his company, Engles Security Training School, which he co-owned and operated, to overcharge the V.A.’s Vocational Rehabilitation and Employment (VR&E) program for services that either were shortened, or not performed altogether. After an extensive federal investigation, Engles was arrested on April 18 then indicted four days later.A Bowie man was indicted on 20 counts for defrauding the United States Department of Veterans Affairs of $300,000, after turning in misleading information about a program for disabled veterans on April 22. (Courtesy Photo)According to the Soldier of Fortune military blog, the formal announcement was made by representatives of the law enforcement agencies who collaborated on the investigation. Assistant Attorney General Brian A. Benczkowski of the Justice Department’s Criminal Division, U.S. Attorney Jessie K. Liu for the District of Columbia, Special Agent in Charge Matthew J. DeSarno of the FBI’s Washington Field Office Criminal Division and Special Agent in Charge Kim Lampkins of the V.A. Office of Inspector General (OIG), Mid-Atlantic Field Office made the public statement after unsealing the indictment.Engles Security became an approved vendor of the VR&E program in 2015. The VR&E program is designed to help disabled military veterans with education and employment-related services. The Temple Hill-based company specialized in security guard and related courses.   The indictment claims Engles falsified documents regarding how he administered it’s course.However, the investigation found evidence that the company provided veterans far less than what Engles presented to the Veterans Administration. He allegedly submitted documents to the V.A. stating that he was providing 15 veterans with months-long courses for 40 hours per week and over 600 total hours.  However, in some instances, he allegedly offered only a few hours of class per day, while claiming that the students were in class for 40 hours per week.According to the indictment, Engles frequently cancelled classes without notice or any provision to make them up. Instructors often were late and ended class early.   Engles is also alleged to have ended some classes after less than a month although he represented to the V.A. that the veterans’ classes would last for several months.The elaborate scheme also included Engles allegedly creating and sending to the V.A. “Certificates of Training” stating that veterans had completed courses that they had not completed or taken.  Engles allegedly submitted letters to the V.A. falsely stating that the veterans had been employed by his private security business.  Engles also allegedly instructed veterans to sign attendance sheets representing that they had attended class sessions, which they didn’t attend.Engles allegedly charged the VA thousands of dollars more for veterans’ courses than he charged non-veterans who took the same or similar courses. The V.A. paid Engles Security over $300,000 for the education of 15 veterans.The FBI’s Washington Field Office and the V.A. OIG are leading the investigating the case.  Trial Attorney Simon J. Cataldo of the Criminal Division’s Public Integrity Section and Assistant U.S. Attorney David Misler of the U.S. Attorney’s Office for the District of Columbia are lead in prosecuting the case.There hasn’t been an announcement about when the trial will begin or what jurisdiction will hear it.last_img read more

Proc Natl Acad Sci USA 114:24 6233-6237. Journal information: Proceedings of the National Academy of Sciences “This phenomenon can be considered a lithography-free method that allows for ready fabrication of arrays of nanomaterials, where their size, length, and periodicity could robustly be tuned,” he continues. “Moreover, not only water but other liquids could be used to carry nanomaterials and to induce the wrinkle-to-fold transition.”Moon describes several examples of potential de novo fabrication and analysis techniques, including nanoscale lithography, nanoimprint, growth by chemical vapor deposition, and chemical reaction. “Our method can potentially be used for the fabrication of 1-dimensional nanowires or nanoarrays for application to DNA analysis with very dilute or small amounts of DNA; DNA templates as new metal or ceramic nanostructures; and DNA treatment devices for healing modified DNA. In addition, one can adopt this technique to handle protein, blood, or nanoparticles at nanoscale.”Košmrlj and Stone tell Phys.org that one area of planned research is focused on nonlinear analysis and modeling for improved quantitative understanding of the capillarity-induced wrinkle-to-fold transition. “Since our system is composed of the mechanical behavior of the fold transition triggered by liquid surface tension, the wrinkle-to-fold transition that we’ve found is associated with large deformations where conventional linear elasticity theory does not apply. While the basic mechanisms can be explained within the linear theory, quantitative comparison with experiments can only be achieved by taking into account geometrical and material nonlinearities. We are therefore performing numerical simulations by coupling liquid surface tension and solid deformation, as well as performing analysis with perturbation series, where nonlinearities of elastic structures can be studied systematically.””I also think that the challenges ahead are to find how to achieve larger areas for DNA pattern formation,” Moon says. “In fact, our latest results—obtained after this PNAS article was accepted—shows some impressive progress for the region with wrinkle-to-fold transition in larger areas, such as the entire area underneath a water droplet. Another area to be studied, Moon continues, concerns the fact that biological morphogenesis of skin–substrate systems are ubiquitous in organisms where water is a major constituent. “We’re trying to find situations where our findings are applicable. Active collaborations with experts in the field would be helpful.” The researchers might also investigate materials other than PDMS. “Yes. other polymers can work if they possess the basic factors to govern the fold transition, these being the thinness of the nano-skin and soft body materials, and surface hydrophilicity to ensure sufficient surface reaction with liquid,” Moon notes. Assistant Professor and lead author So Nagashima, Assistant Professor Andrej Košmrlj, Donald R. Dixon ’69 and Elizabeth W. Dixon Professor Howard A. Stone, and Principal Research Scientist Myoung-Woon Moon discussed the paper they and their co-authors published in Proceedings of the National Academy of Sciences. “I think that the most challenging aspect of devising our method for utilizing a thin skin template that responds to water by dynamically changing its surface morphology was finding the conditions where the wrinkle-to-fold transition occurs,” Moon tells Phys.org. “The critical conditions as a function of the applied strain, initial wrinkle geometries, and thickness of the skin layer determined by oxygen plasma treatment duration were difficult to find.” Moon adds that the observation technique for the dynamic transition was limited to only optical microscopes whose highest optical resolution falls between 100 to 1000 nm in the width of nanowires, this being due to the dynamic transition taking place at the submicron scale.When inducing a template surface wrinkle-to-fold transition by exploiting the capillary forces of water containing DNA molecules, Stone points out, the observation that water changes the wrinkle-to-fold transition is new. “As far as we know, ours is the first study to show this effect, as is demonstrating one use of such folds for the alignment of DNA. Moreover, control of surface tension or resultant capillary forces and the area for fold formation is relatively hard—and by adding DNA molecules to water, it appears that the surface tension is changed, so the fold transition length was shorter.”Template preparation used an oxygen plasma treatment of prestretched polydimethylsiloxane (or PDMS, a polymeric organosilicon compound) substrates for varying durations. “In fact,” Moon explains, “the manipulation of PDMS with prestretching strain is a relatively well-developed method as is the oxygen plasma treatment: both have been discussed in the literature. We can make the samples with various sizes of a few millimeters to a few centimeters, which can be also made on much larger area.” Moon notes that the researchers can also vary polydimethylsiloxane’s mechanical properties—to make it more stretchable, soft or flexible—by changing the ratio of elastomer and cross-linker for PDMS preparation.

In addition, Moon adds, smaller substances such as biomolecules or nanoparticles can follow the water channel to form aligned 1-dimensional nanostructures. “Smaller is better. Less is more. We’ve found that the wrinkle-to-fold transition takes place more easily when the following factors become smaller: compression level, skin thickness, droplet volume, size of the sample surface, and static contact angles of droplets.”Based on their findings, the authors stated that their approach could lead to new ways of fabricating functional materials. “Our key finding is that one can change wrinkles into localized folds by simply exploiting the capillary forces of water on wrinkled surfaces under very small strain of about 1% in compression,” Nagashima tells Phys.org. “Recent studies reported in the literature have demonstrated that such wrinkle-to-fold transitions can help develop systems that dynamically change their properties according to the surface morphology. However, inducing the transition in the absence of water is difficult to achieve in practice because, in general, large compression needs to be applied to the skin-substrate system, which hinders wider applications. Our study reveals that even 1% of compression, which is the critical level for creating wrinkles in our case, is large enough to trigger the transition to folds locally when water is present.” Nagashima notes that while the compression level required to induce the transition might differ according to the skin-film system used, only a small compression level would be necessary in combination with water.

Proc Natl Acad Sci USA 114:24 6233-6237. , Science (Phys.org)—Nanowires fashioned from DNA (deoxyribonucleic acid)—one of several type of molecular nanowires incorporating repeating molecular units—are exactly that: Geometrically wire-like DNA-based nanostructures defined variously as having a 1~10 nm (10−9 m) diameter or a length-to-diameter ratio >1000. While nanowires can be made from several organic and inorganic materials, DNA nanowires have been shown to provide a range of valuable applications in programmed self-assembly1,2 of functional materials—including metallic and semiconductor nanowires for use in electronic devices—as well as biological, medical, and genetic analysis applications3,4,5. That being said, DNA nanowire adoption has been limited due to historical limitations in the ability to control their structural parameters—specifically, size, geometry and alignment. Recently, however, scientists at Korea Institute of Science and Technology and Princeton University leveraged the capillary forces of water containing DNA molecules to demonstrate size-controllable straight or undulated aligned DNA nanowires that were spontaneously formed by water entering wrinkled channels of a compressed thin skin on a soft substrate, which subsequently induced a wrinkle-to-fold transition. © 2017 Phys.org This document is subject to copyright.

Colombians angry after 32 children killed in bus fire

first_imgBOGOTÁ, Colombia – Colombians voiced anger Monday after 32 children burned to death when an overcrowded bus burst into flames as authorities arrested the driver who was seen fleeing the inferno.Authorities have arrested the driver who, according to a survivor, had gotten off the bus to refuel with a jerrycan when flames suddenly engulfed the vehicle on Sunday.The children, aged 3 to 12 years old, were returning from evangelical church services in the small northern town of Fundación. The driver lost two of his own children in the tragedy.Fundación Mayor Luz Stella Durán said another 20 were hospitalized. Most of the injured have second- or third-degree burns. She declared three days of mourning and banned alcohol consumption.President Juan Manuel Santos, who rushed to the scene to console grieving families, said an investigation was underway while many Colombians denounced the accident as an example of the country’s poor enforcement of road safety.“I am shattered, the entire country is in mourning for the death of these children,” Santos said.  “We will go through everything with a fine-toothed comb.”Crews at the scene pulled little charred bodies from the blackened wreckage before transporting them to the medical examiner’s office in the regional capital of Barranquilla to be identified — a task which could take days.Authorities said the explosion occurred around noon, and that the fire was so intense they had problems determining the number of casualties.Driver without license flees The bus driver turned himself in to police after the relatives of victims chased him and hurled rocks at his home.He was due to appear at a court hearing to explain himself.The prosecutor’s office said the driver lacked a license to drive and was under investigation.Transport Minister Cecilia Álvarez said the bus had lacked the authorization to provide services since 2012.“It is an illegal vehicle that also lacked transport insurance,” Álvarez told RCN radio, adding that the initial investigations are leaning toward “driver recklessness.”The driver apparently used contraband gasoline to refuel the bus, the minister said.Local media quoted an 11-year-old girl who lost two brothers as saying that, at one point, the driver got off the bus to refuel while his young charges remained on board.“Sparks flew,” she recalled. “It was then that the driver went to get water and then he left,” she said. “I broke a window and got my little sister out but I couldn’t save my two brothers.”The tragedy became a political issue ahead of Sunday’s presidential election, in which Santos is seeking a second term.Leftist candidate Clara Rojas said the accident “shows the country’s backwardness.”“It is not only the driver’s irresponsibility. It is also the lack of rigor and presence of the authorities,” she said.Colombians vented their fury on Twitter, one user with the handle @manialolita calling it “another tragedy foretold” while @ALCISERRATO said “the state does not fulfill its duty.” Facebook Comments Related posts:32 children burn to death in Colombia bus accident Cúcuta: Colombia’s city of contraband and a broken Bolivarian dream Colombia suspends peace talks with FARC after general kidnapped Demining Colombia will take ‘a generation’: ministerlast_img read more
