Quebec domestic violence victim awarded 315000 in civil suit against attacker

first_imgMONTREAL — A court has awarded a Quebec woman who was violently attacked by her longtime partner $315,000 in damages in a decision her lawyer hopes will provide victims of domestic violence another avenue to obtain justice.The woman, whose identity is not revealed in the court documents, testified that the attack took place while she was confined for three days in September 2012.Court documents says she was beaten and bruised by Craig O’Brien, with whom she had been in a common law relationship for seven years — a union that became increasingly toxic over time.O’Brien testified that he was extremely intoxicated and could not remember the extent of the injuries he inflicted, which included a broken finger, multiple contusions and lacerations. He also prevented her from eating, and she testified that she was certain she was going to die.She managed to escape when O’Brien went on the balcony to smoke, and she called police in the Montreal suburb of Laval.He pleaded guilty to charges including unlawful confinement, assault and aggravated assault. He was sentenced by a Quebec court judge to eight months in jail, serving just a few months.In 2015, the woman decided to sue for damages in Quebec Superior Court.“She was outraged that after everything that had been done to her, this fellow would only spend three months in jail,” said lawyer Daniel Romano. “She wanted justice. She wanted to be compensated for what she’d actually lost, and she wanted to serve as an example to other women.”In a decision dated Nov. 20, Justice Pierre Journet agreed she was entitled to compensation.While she’s now gone through counselling and has began rebuilding her life, the court ruling described the lasting psychological impact of the hold he had on her.The judge noted in his ruling O’Brien did not express remorse and instead argued his partner could have left if she had been fearful.“All of the violent assaults during these days left her with post-traumatic stress that still affects her,” Journet wrote.“He controlled her, satisfied his war-like instincts on her, threatened her with reprisals during their life together and wounded her in a savage and unforgivable assault.”Louise Riendeau, who heads an organization that represents shelters for abused women, said cases awarding damages are rare — she’s only heard of a handful in recent years.Not all women will have the resources to go to court, she said, but the ruling sends a strong message.“It’s a way for them to have recognized the hardship they went through,” she said. “It’s a way for women to retake power in those instances, to have the sentiment that they were victimized.”The damages include $113,000 plus interest to compensate for lost salary, dental benefits, pension contributions and to reimburse credit card debt from a card she’d let him use.O’Brien is ordered to pay an additional $125,000 in damages and $75,000 in punitive damages —  $25,000 for each day she was unlawfully confined.“In this case, we wanted to set a very, very clear precedent,” Romano said. “We’ve accomplished that, it’s a very positive step forward.”Sidhartha Banerjee, The Canadian Presslast_img read more

DeMarcus Cousinss Kings Loved To Blow Leads — And Mount Huge Comebacks

There’s been no shortage of attention on the Sacramento Kings in the wake of their mind-boggling choice to deal DeMarcus Cousins to New Orleans for pennies on the dollar. But one thing that’s garnered almost no scrutiny is the inconsistency of the team’s play.The Kings this season have lost a league-worst five games in which they once held a lead of 15 points or more, according to NBA Miner, a site that tracks advanced and unusual statistics. But they’ve also tied for an NBA-best four wins in contests that they once trailed in by 15 points or more. How are those two things even possible?Well, it helps when you’re as inconsistent as the Kings are. Sacramento is the NBA’s worst team in first halves by far yet owns the league’s 10th-best net rating1A net rating measures how many points a team outscores an opponent by — or is outscored by — for every 100 possessions. in second halves (even better than the defending-champion Cavs). Those numbers fit the pattern of what’s happened in the team’s craziest outcomes: Three of Sacramento’s four major comebacks this season began during the third quarter, while four of the Kings’ five collapses began unraveling in the second quarter.In the comebacks, the Kings often had trouble containing opposing forwards — Andrew Wiggins, Gordon Hayward, Tobias Harris and Paul Millsap, among others — in the early going. But Sacramento wisely dumped the ball into Cousins, who repeatedly drew fouls and visits to the line during second halves, which allowed his team to play catch-up with the clock stopped. This especially worked in a 94-93 win over Utah, in which Cousins shot 10 free throws in the fourth quarter without taking a single field-goal attempt.During the back-breaking losses, the slow-paced Kings have often been outrun by their opponents. In a game on Nov. 10, the Lakers outscored Sacramento 13-4 in second-half fast-break points, according to NBA.com. The Warriors outscored the Kings 21-3 in fast-break scenarios during the second half of their Jan. 8 comeback. And the Pacers finished with a 22-0 second-half advantage in fast-break scoring over the Kings en route to a come-from-behind victory on Jan. 18. (Sacramento’s 3-point defense, one of the worst in the NBA, was also less than stellar in those second-half efforts.)Cousins obviously had a ton to do with the Kings’ outcomes in these games — particularly in a 3-point loss to the Sixers in which he had 46 points but fouled out in the final minute. But the loss of Rudy Gay, out for the season, arguably had a bigger impact in some cases.Gay tore one of his Achilles tendons in the midst of one of the collapses, with the Kings up by 10 against Indiana in a Jan. 18 contest that Sacramento once led by 22. Gay’s injury took a psychological toll on the club that night, Cousins told reporters after the game. Cousins shot 0-for-9 with six turnovers after halftime.And there was a tangible difference in the team’s play. Without Gay’s ability to ease some of the scoring burden (his 26 percent usage rate was the team’s second-highest before the team remade itself at the trade deadline), Cousins was overworked in some fourth periods. His fourth-quarter usage rate jumped to 57.5 percent during the last week and a half of January, after Gay’s injury, up from 37 percent earlier in the same month. That’d be asking too much of anyone — let alone the NBA’s most double-teamed post player.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/02/cousinsnorudygay.mp400:0000:0000:16Use Up/Down Arrow keys to increase or decrease volume.Things will change considerably now that Cousins is in New Orleans. The Kings can only hope that the move allows for increased stability, and perhaps fewer blown leads, going forward.Check out our latest NBA predictions. read more

Ohio State womens ice hockey crushed twice in Wisconsin

Then-sophomore forward Katie Matheny (23) skates down the ice during a game against New Hampshire on Oct. 4, 2014 at the Ohio State Ice Rink. OSU won, 4-3. Credit: Lantern file photoAgainst the high-scoring Wisconsin Badgers, the Ohio State women’s hockey team failed to sustain momentum after its opening-weekend victories against Lindenwood, getting dismantled twice.The Buckeyes allowed 15 goals on 102 shots in the two games, including a combined five first-period goals. Conversely, the Scarlet and Gray only took a combined 29 shots of its own in the two games.The third-ranked Badgers’ goal scoring opened early on Saturday when sophomore forward Emily Clark tallied a point 30 seconds into the game. The Badgers would proceed to score three goals on the power play in the third period of the first game, en route to topping the Buckeyes 7-0.Special teams play had been an emerging strength for OSU early in the season, but the series against Wisconsin demonstrated that there is still plenty of work to be done. In addition to the three goals the Buckeyes allowed with a player in the box, the Badgers scored a goal while on the penalty kill on Saturday. The Buckeyes went 0-of-4 in power-play opportunities on Sunday, which ended as another lopsided loss by the final score of 8-0.The squad’s strongest period of play from the weekend was the second period on Sunday, when OSU recorded nine shots on goal and successfully killed two penalties, and despite the penalties was able to control the pace of play for much of the period. The Buckeyes will look to get back on track when they return to Columbus for their first home series of the season against Minnesota beginning on Friday. The puck is set to drop in the first game at 6:07 p.m. and 2:07 p.m. the following day. read more

Border Patrol arrests 32 at San Diego demonstration

first_img Categories: Local San Diego News, National & International News Tags: Immigration FacebookTwitter December 10, 2018 AP, Border Patrol arrests 32 at San Diego demonstration AP Posted: December 10, 2018 SAN DIEGO (AP) — U.S. Border Patrol agents arrested 32 people at a demonstration Monday that was organized by a Quaker group on the border with Mexico, authorities said. Demonstrators were calling for an end to detaining and deporting immigrants and showing support for migrants in a caravan of Central American asylum seekers.A photographer for The Associated Press saw about a dozen people being handcuffed after they were told by agents to back away from a wall that the Border Patrol calls “an enforcement zone.” The American Friends Service Committee, which organized the demonstration, said 30 people were stopped by agents in riot gear and taken into custody while they tried to move forward to offer a ceremonial blessing near the wall.Border Patrol spokesman Theron Francisco said 31 people were arrested for trespassing and one was arrested for assaulting an officer.More than 300 people, many the leaders of churches, mosques, synagogues and indigenous communities, participated in the demonstration at San Diego’s Border Field State Park, which borders Tijuana, Mexico.The rally held on a beach divided by the border wall was the second confrontation for Border Patrol agents since a caravan of more than 6,000 migrants, predominantly Hondurans, reached Tijuana last month. A confrontation with rock-throwers from Mexico led to U.S. agents firing tear gas into Mexico on Nov. 25 and a five-hour closure of the nation’s busiest border crossing.Thousands of migrants are living in crowded tent cities in Tijuana after undertaking a grueling journey from Central America to the U.S. border. Many face waiting weeks or months in Mexico while they apply for asylum. The U.S. is processing up to about 100 claims a day at the San Diego crossing, which is creating a backlog.The demonstration Monday was meant to launch a national week of action called “Love Knows No Borders: A moral call for migrant justice,” which falls between Human Rights Day on Monday, and International Migrants’ Day on Dec. 18, the group said.“Showing up to welcome and bless children, mothers and fathers seeking asylum from very difficult and dehumanizing circumstances is the right and humane thing to do,” said Bishop Minerva G. Carcano, from the San Francisco Area United Methodist Church. “How we act in these moments determines who we will become as a nation.”The group also is calling on Congress to defund Immigration and Customs Enforcement and Customs and Border Protection.RELATED STORY: Advocacy group walks to show support for asylum seekers at US-Mexico border last_img read more

California Assembly approves phone bill fee to improve 911 system

first_img June 18, 2019 Posted: June 18, 2019 California Assembly approves phone bill fee to improve 911 system SACRAMENTO, Calif. (AP) — California lawmakers are negotiating a pair of proposed tax increases as the deadline approaches for Democratic Gov. Gavin Newsom to sign a $214.8 billion operating budget.Lawmakers approved the budget bill last week, but lawmakers still must pass more than a dozen “trailer bills” that detail how the money must be spent.Monday, the state Senate approved a plan to raise taxes on some business income and give that money to people who earn less than $30,000 a year in their annual tax refunds. The Assembly, meanwhile, approved a fee of up to 80 cents per month on phone bills — including cell phones — to pay for an upgrade to California’s aging 911 system following the most devastating wildfire season in state history.The businesses taxes are a tough vote in the Assembly , where Democrats in power have concerns about voting to align the state’s tax code with a portion of the 2017 federal tax law signed by Republican President Donald Trump. The 911 fee is a tough vote in the Senate, where lawmakers are wary of voting again on a cell phone fee after a similar proposal fell one vote shy of passing last year.Lawmakers in both chambers breezed through a series of trailer bills on Monday that did things like temporarily suspend taxes on diapers and tampons and extend the state’s paid family leave program by two weeks. Lawmakers passed each one with little debate and with bipartisan agreement on several points.But the Legislature is poised for a pair of critical votes on Thursday on the 911 fee and business taxes, with leaders in both chambers trying to pressure the other one to vote.“It is really kind of part of our strategy to make sure one house takes a vote that may feel difficult by the other house, and vice versa,” said Sen. Holly Mitchell, a Los Angeles Democrat and chairwoman of the Senate Budget Committee. “I think those are appropriate dots to connect.”The business tax changes are part of a plan to selectively adopt some of the federal tax changes Trump signed into law in 2017. Some items would lower taxes and others would increase them. Overall, the state would get an additional $1.6 billion in revenue during the fiscal year that begins July 1.Newsom wants to use most of that money to triple the state’s earned income tax credit program, which boosts the size of annual tax refunds for low-income people. The plan would make about 1 million more people eligible for the credit. Plus, it would give $1,000 to people who make less than $30,000 a year and have at least one child under 6.But the plan would still not include immigrants who pay taxes but do not have Social Security numbers. Newsom would not include that in the budget because he said it was too expensive, but pledged to work toward it in future years.In an effort to win votes, lawmakers have stopped referring to the bill as “conforming” to the federal tax code, but instead call it “loophole closure.” Assemblyman Adam Gray, a moderate Democrat from Merced, supports the bill. He said he has never seen “so much consternation” about a tax bill, noting lawmakers often conform to federal tax changes without controversy.The 911 fee is an effort to upgrade the state’s system so it can handle text messages, photos and videos. But the fund that pays for the system is based on a fee for each phone call. The fund has been steadily declining as more people opt to send text messages.Assemblyman Jay Obernolte, R-Big Bear Lake, argued that the state should use some of its surplus to pay for the changes rather than raise fees on consumers. But Assemblywoman Christy Smith, D-Santa Clarita, argued that the state’s 911 system is essential and requires funding beyond a short-term surplus.“Yes, we have a surplus. But we don’t always have a surplus in California,” she said. “We will always have emergencies.” Categories: California News, Local San Diego News FacebookTwitter AP, AP last_img read more

FDA says buying young peoples blood wont keep you from aging

first_img Plasma is the liquid part of blood that contains proteins to help with clotting. It can be used to manage bleeding. Patients whose blood is unable to clot can benefit from plasma, though there are still risks such as allergic reactions. Plasma infusions from young donors can involve administering large amounts of plasma, which can be linked with infectious, allergic, respiratory and cardiovascular risks, according to the FDA. Some people have charged thousands of dollars for infusions that haven’t been proven to be effective, the agency said. “Simply put, we’re concerned that some patients are being preyed upon by unscrupulous actors touting treatments of plasma from young donors as cures and remedies,” Gottlieb and Marks said. “Such treatments have no proven clinical benefits for the uses for which these clinics are advertising them and are potentially harmful.”The administration said it’ll consider taking actions against companies that abuse patients’ trust and that endanger their health, whether through their manufacturing conditions or by promoting purported treatments that haven’t been proven safe or effective.Following the FDA’s statement, Ambrosia Health, a startup that charged thousands of dollars for plasma infusions from young donors, said on its site that it has stopped patient treatments. The company didn’t immediately respond to a request for comment.People considering plasma treatments should ask their health care provider if the FDA has reviewed a treatment before proceeding, the agency said. It’s also asking patients and health care providers to report negative side effects linked to treatments using plasma from young donors, for aging or similar conditions, to the FDA’s MedWatch Adverse Event Reporting program. The FDA said it’ll monitor the issue and take appropriate steps with state and local health departments and blood establishments. First published Feb. 19, 2 p.m. PT.Update, Feb. 20 at 9:43 a.m.: Adds that Ambrosia Health has stopped patient treatments following the FDA’s statement.  CNET Next Big Thing: The Invisible Doctor Sci-Tech Wellness Tags Now playing: Watch this: 0center_img 59:45 Wladimir Bulgar/Getty Images If you’re planning on getting infused with young blood to fight memory loss and aging, the US Food and Drug Administration would like you to reconsider. FDA Commissioner Scott Gottlieb and Peter Marks, director of the Center for Biologics Evaluation and Research, warned in a statement Tuesday against getting infused with blood plasma from young donors. Claims that these infusions can help treat conditions such as dementia, Parkinson’s disease, Alzheimer’s disease, heart disease and post-traumatic stress disorder haven’t been clinically proven, the FDA said. Read more: FDA cleared vs FDA approved: You should know the difference | FSA vs. HSA: What’s the difference? | 14 unexpected things you can buy with your FSA”We have significant public health concerns about the promotion and use of plasma for these purposes,” Gottlieb and Marks said. “There is no proven clinical benefit of infusion of plasma from young donors to cure, mitigate, treat, or prevent these conditions, and there are risks associated with the use of any plasma product.”The FDA said it’s alerting consumers and health care providers that treatments using young blood haven’t gone through the appropriate testing to confirm their therapeutic benefit and safety. Therefore, these infusions shouldn’t be considered safe or effective, and consumers shouldn’t get the infusions beyond clinical trials with an institutional review board and regulatory oversight, it said.

Tiny robot nanofish may one day deliver drugs inside the body

first_imgCredit: Small (2016). DOI: 10.1002/smll.201601846 Explore further Journal information: Small (Phys.org)—A combined team of researchers from the Harbin Institute of Technology in China and the University of California in the U.S. has developed a nano-sized, remotely controlled fish that is able to swim in liquids when a magnetic field is applied. The team has published the details of their research in the journal Nano Small Micro. Play Credit: Small (2016). DOI: 10.1002/smll.201601846 There are still some big issues to address with the tiny fish, the team acknowledges—one of which is how to rid the body of the swimmers after they have delivered their package. One solution they suggest is using material that at some point is biodegradable. There is also the cost—the amount of precious metals used to create a single fish would be small, but it could add up quickly if hundreds of the fish were used to deliver doses of medicines. Also, it would seem that a means for tracking the fish would have to be developed to allow for micro-steering. This document is subject to copyright.

Magnetically Propelled Fish-Like Nanoswimmers, Small (2016). DOI: 10.1002/smll.201601846AbstractThe swimming locomotion of fish involves a complex interplay between a deformable body and induced flow in the surrounding fluid. While innovative robotic devices, inspired by physicomechanical designs evolved in fish, have been created for underwater propulsion of large swimmers, scaling such powerful locomotion into micro-/nanoscale propulsion remains challenging. Here, a magnetically propelled fish-like artificial nanoswimmer is demonstrated that emulates the body and caudal fin propulsion swimming mechanism displayed by fish. To mimic the deformable fish body for periodic shape changes, template-electrosynthesized multisegment nanowire swimmers are used to construct the artificial nanofishes (diameter 200 nm; length 4.8 μm). The resulting nanofish consists a gold segment as the head, two nickel segments as the body, and one gold segment as the caudal fin, with three flexible porous silver hinges linking each segment. Under an oscillating magnetic field, the propulsive nickel elements bend the body and caudal fin periodically to generate travelling-wave motions with speeds exceeding 30 μm s−1. The propulsion dynamics is studied theoretically using the immersed boundary method. Such body-deformable nanofishes exhibit a high swimming efficiency and can serve as promising biomimetic nanorobotic devices for nanoscale biomedical applications.

To that end, they connected gold and nickel segments together with silver hinges—the outer segments made of gold serve as the head and tail, while the inner segments serve as the fish body. Each of the segments are just 800 nanometers in length and the complete fish is a hundred times smaller than a single grain of sand.The fish is caused to swim by applying an oscillating magnetic field that forces the head and tail to swing, which in turn propels the fish forward. The direction the fish takes and the speed at which it moves can be controlled by manipulating the position and speed of the oscillating magnet. The purpose of such nanoswimmers, the team proposes, is to carry medicine to a particular part of the body, thereby reducing the need for surgery or overuse of drugs that can cause negative side effects in other parts of the body. An accompanying video demonstrates not only the ease with which the fish can be controlled, but the speed at which they can travel—an obvious improvement over other nano-delivery systems.
