Report Feds got seat complaints on van model teen died in

first_imgCINCINNATI — Federal regulators received nearly 180 seating complaints about Honda Odyssey minivans over the years, according to a newspaper’s investigation after a teenage boy died trapped in one such van.A coroner said 16-year-old Kyle Plush, of Cincinnati, died April 10 of asphyxiation because his chest was being compressed. It’s suspected the 2004 minivan’s rear, third-row seat flipped over and pinned him as he reached into the back.The Cincinnati Enquirer reported its investigation shows that a quarter of Odyssey seating complaints were over stability and that one of five stability cases involved problems with third-row seats.More than a dozen warnings about the Odyssey’s third-row seating for models made between 1999 and 2012 were found by the newspaper. Some complaints said seats were loose, rusting or wouldn’t latch; others noted instances when heavy seats suddenly slammed down or flipped out of place.The Enquirer also reports it obtained documents showing local investigators inspecting the minivan indicated that they had difficulty getting the rear seat to latch in place and that it would “rotate freely” after appearing to be locked.Honda said in an emailed statement Wednesday that it hasn’t received any direct claims of fatal injuries from “interaction with third-row seats” in 1999-2004 Odysseys.Honda spokesman Chris Martin said that the automaker has requested permission to inspect the Plush vehicle but hasn’t received it and doesn’t have any specific information “from which to definitively determine what occurred in this incident.”Martin also said there were no seat-related recalls of the 2004 Honda Odyssey in the United States.Honda last year recalled some 900,000 later-model Odysseys because of concerns about second-row seats tipping forward if not latched properly.The National Highway Traffic Safety Administration told The Enquirer that it worked closely with local authorities and Honda to “understand what happened” in the Cincinnati death.“Based on the available information, including internal data analysis, the agency has not found evidence of a vehicle safety defect trend,” the agency said.The NHTSA said part of its review included past Odyssey complaints and it would “continue to monitor complaints” and “take further steps as appropriate.”The agency didn’t immediately respond Wednesday to an Associated Press message seeking further comment.The teen’s father found his son dead nearly six hours after the first of Kyle’s two 911 calls seeking help. Two officers sent in response to the student’s first 911 call drove through parking areas around the school but didn’t get out. Police have said they didn’t have information needed to narrow their search.A prosecutor determined that no one would face criminal charges in the death. The family has expressed frustration over what they say are incomplete explanations and the slow pace of reforms in emergency response. The city already has been upgrading smartphone communications, computer-assisted dispatch, police in-car mapping, and training.The Enquirer reported that the Plush family didn’t respond to messages seeking comment on the newspaper’s investigation.___Information from: The Cincinnati Enquirer, http://www.enquirer.comThe Associated Presslast_img read more

Geoscience BC Open House in Dawson Creek

first_imgGeoscience BC shares they have launched a new project to assess the potential amplification of ground movement associated with earthquakes generated by hydraulic fracturing and fluid injection in an area around Fort St. John and Dawson Creek.According to Geoscience BC, the project addresses public concerns relating to seismicity and oil and gas industry activity in northeastern BC, especially in areas close to communities and infrastructure. The project will examine how seismic waves from earthquakes can potentially be amplified in specific shallow geological conditions. Lead researcher Dr. Patrick Monahan said, “Most recent studies in this area have focussed on the reduction of ground motion as you get further from the seismic event. But seismic ground motions can also be amplified significantly on sites underlain by certain sediments, compared to sites on bedrock or firm ground.” Geoscience BC Executive Vice President and Chief Scientific Officer Carlos Salas said, “The new science generated by this project will help us better understand which areas have the potential of increased ground motion during induced seismicity events associated with natural gas extraction. The information can be used by industry, regulators, communities in the Peace River Regional District and Indigenous groups to improve industry procedures to manage felt events.” DAWSON CREEK, B.C. – An open house is being held in Dawson Creek by Geoscience BC regarding a new project to assess the potential amplification of ground movement around Fort St. John and Dawson Creek.Join Geoscience BC staff and lead researcher Dr. Patrick Monahan to learn more about the project at the open house on the evening of Wednesday, May 29, 2019, from 5:30 pm to 7:00 pm at the Kiwanis Performing Arts Centre – Meeting Room 1, 10401 10 Street, Dawson Creek.The event is free and open to anyone to attend. , light snacks and non-alcoholic drinks will be provided, register for the event; CLICK HERElast_img read more

Naya Pak should demonstrate Naya action on terror India

first_imgNew Delhi: Pakistan will be judged not by words but on basis of the action it takes to dismantle terror infrastructure on its soil, India said Saturday, asserting that its non-military strike on the JeM terrorist training camp in Balakot achieved its desired objective.External Affairs Ministry Spokesperson Raveesh Kumar said if Pakistan claims to be a ‘naya Pakistan’ (New Pakistan) with a ‘nayi soch’ (new thinking), then it should demonstrate ‘naya’ action (new action) against terror groups operating with impunity from its soil. Also Read – How a psychopath killer hid behind the mask of a devout laity!The MEA’s comments came a day after Pakistan Prime Minister Imran Khan said he will not allow Pakistani soil to be used for terror directed at other countries. Khan has been saying that a ‘Naya Pakistan’ is embarking on a new journey under his leadership. Kumar said Pakistan has been making identical statements after separate terror attacks and now Islamabad will have to take up the concrete action the international community expected it to take and must rein in terror groups operating from its soil. Also Read – Encounter under way in Pulwama, militant killed”We remain resolute in our determination to persuade the international community of the necessity of compelling Pakistan to move beyond mere words and to show credible, verifiable and sustained actions. We have and we will continue to act with responsibility and maturity,” he said at a media briefing. Kumar said the widespread presence of terrorist camps in Pakistan is public knowledge and repeated requests by India and the international community for Pakistan to take action against such groups has been met with “denial”. “In 2004, the then President of Pakistan had made a solemn public commitment that they would not allow any territory under their control to be used for terrorist activity in any manner,” he said. “But till today, however, Pakistan has failed to take any credible action against Jaish-e-Mohammed and other terrorist organisations, which continue to operate with impunity from Pakistan,” he said, adding Pakistan will be judged not by its words but on the basis of action it takes to dismantle terror infrastructure. Tension between the two nuclear-armed neighbours escalated after the February 14 Pulwama terror attack and subsequent aerial strike by India on a training camp of the Jaish-e-Mohammed (JeM) in Balakot on February 26. Pakistan retaliated the strike next day by unsuccessfully attempting to target Indian military installations. The JeM claimed responsibility for the Pulwama attack. “Our non-military counter terrorism strike of February 26 achieved the intended objective. It has demonstrated our firm resolve to take decisive action against cross-border terrorism,” Kumar said about Balakot strike. He, however, evaded questions on number of casualties in the strike.last_img read more

Lenders still hope for successful bids for grounded airline

first_imgNew Delhi: A day after Jet Airways suspended all its flights after running out of money, lenders to the carrier Thursday said they were “reasonably hopeful” that bidding process for the airline will end successfully. Lenders led by the State Bank of India had declined to extend more funds to Jet, forcing it to suspend all its flights. “The lenders after due deliberations decided that the best way forward for the survival of Jet Airways is to get the binding bids from potential investors who have expressed EOI (Expression of Interest) and have been issued bid documents on April 16,” a statement by lenders said. A consortium of 26 lenders led by the SBI, with 51 per cent stake in the debt-trapped airline, has invited bids from potential suitors. Also Read – Thermal coal import may surpass 200 MT this fiscal”Lenders are reasonably hopeful that the bid process is likely to be successful in determining the fair value of the enterprise in a transparent manner,” it said. Banks on Wednesday rejected an immediate Rs 400 crore demand of Jet Airways, compelling it to ground operations. Jet had been, over the last few months, on a decline as competition from budget airlines hurt its profitability and led to a debt pile. It reported losses for four straight quarters despite sales holding up. Also Read – Food grain output seen at 140.57 mt in current fiscal on monsoon boostAt its peak, Jet operated 123 planes and over 600 daily flights. It was flying just seven planes on Tuesday. Its chief executive officer Vinay Dube on Wednesday wrote an email to airlines’ passengers saying “with deep sadness and with a heavy heart that we would like to share with you that, effective immediately, Jet Airways will be suspending all its domestic and international operations”. “Tuesday night, we were informed by SBI, on behalf of the consortium of Indian lenders, that they are unable to consider our request for interim funding. Since no emergency funding from the lenders or any other source of funding was forthcoming, it would therefore not have been possible for us to pay for fuel or other critical services to keep the operations going,” he wrote. He said the airline had over the last several weeks and months tried “every means possible” to seek funding, both interim as well as long term funding, to keep our operations going. “Unfortunately, despite the very best of our efforts, we have been left with no other choice today”. “A decision like this is never easy to make, but without the interim funding, which we have been repeatedly requesting for, we are simply unable to conduct flight operations in a manner that delivers to the very reasonable expectations of our guests, employees, partners and service providers,” he wrote. “After 25 years of sharing the Joy of Flying with Indian and international guests, Jet Airways and its Board of Directors have been forced to take this extreme measure, as prolonged and sustained efforts with lenders and authorities to ensure the sustainability of the airline did not yield the desired results.” He, however, said the future provides new hope and opportunity as India is better off with a flying Jet Airways. “We will now await the bid finalization process by SBI and the consortium of Indian lenders and will continue to support the bid process initiated by the lenders,” he added.last_img read more

Commentary Sir Charles sermon still rings true today

Charles Barkley is a prophet. But not for thinking the Bulls are going to beat the Heat, because that’s not going to happen. For the record, the Mavericks won’t be toppling Miami’s trio either. No, the “Round Mound of Rebound” 1993 Nike commercial makes him clairvoyant: “I am not a role model. I am not paid to be a role model. I am paid to wreak havoc on the basketball court. Parents should be role models. Just because I dunk a basketball doesn’t mean I should raise your kids.” It’s an immutable truth. But, unfortunately, it doesn’t reflect the real world. Growing up, my favorite athlete was Ken Griffey Jr. I loved everything about him. I gawked at his poetry-in-motion swing. I reveled in the fact that he was a true five-tool player in for most of his career. And, as a native of Cincinnati, I felt extreme pride that he grew up in the Queen City and spent eight-plus seasons playing for the Reds. Most of all, I admired Griffey for constantly having a smile on his face. He thoroughly enjoyed playing the game of baseball. But at no point did I consider Griffey a role model. Luckily for me, I had my mom, my dad and my grandpa to emulate. Many other kids aren’t so lucky. They grow up in fragmented families, often with one, or even no, parent or guardian to speak of. Those people, not professional athletes, should serve as life’s prototypes for kids. It’s a shame some children aren’t even given a choice. Both role models and athletes have character flaws, but the difference is, your parents’ mistakes won’t be broadcast on ESPN or dissected in discussion boards over the Internet. Instead, your parents can have their cake and eat it too. They can sit you down and chat about your mistakes and also their own errors in judgment. Michael Jordan, on the other hand, can’t walk through your front door, sit down on your couch and open up about his past gambling addiction or divorce. Furthermore, it’s hard to trust an athlete to set the right example. Marion Jones, Barry Bonds, Mark McGwire, Sammy Sosa, Tiger Woods and LeBron James: All of them are professional athletes who, at some time, have captivated the attention of sports fans and even non-sports aficionados with their skills and runs on the history books. Jones, Bonds, McGwire and Sosa cheated. Woods cheated on his wife many times over. James cheated the idea of tactfulness. The truth is clear: Barkley’s right — don’t try to “Be like Mike.” Unless, of course, that’s your father’s name. read more

Hughton focuses on the positives after Burnley loss

first_imgAfter losing 1-0 at Burnley on Saturday, Brighton & Hove Albion manager Chris Hughton says he’s delighted his team took six points from three games in a week.Brighton defeated Huddersfield away and Crystal Palace at home, before losing 1-0 to Burnley at Turf Moor, and Hughton feels they should not beat themselves up considering they won six points.“Overall I’ve got to be delighted. After the first two games, if we’d come here [Turf Moor] and not turned up, then it would have been a disappointing end to the week,” Hughton told the club’s website.“But I think we came here and had a go — I can’t accuse the players of not having a go — so we have to look at the week as not being bad.“We’ve played 16 games and nine of them have been away from home, so that’s also something to take into consideration.Pep Guardiola: “Aymeric Laporte’s injury doesn’t look good” Andrew Smyth – August 31, 2019 Manchester City boss Pep Guardiola admits Aymeric Laporte’s injury “does not look good” and fears the defender will be out for a long time.“What pleases me is that outside of that top six, most teams can give one another a run. We’ve probably proved that at our best we are a match for any team outside of the top six.“What Burnley did last season was a wonderful feat, but you’ve got to have so many things going for you. Can that happen in the future? Well, that’s the future.“Our thoughts are still about improving ourselves and trying to make sure the gap to the bottom three is as big as possible.“At the moment it’s just about establishing ourselves. I still like to see us as a developing club and we’ll see where that takes us.”last_img read more

Can expert reasoning be taught

first_img“Students who are used to working on well-structured problems struggle when confronted with the multiple challenges of more complex tasks.” writes Professor Ogilvie (Iowa State University), who not only assigns context-rich problems in his course but has also begun researching their effect on the problem-solving strategies adopted by students. The problems are implemented in a computer-assisted learning environment of his own design. When a student group logs into the system, a context-rich problem is presented with a selection of information resources that may or may not be relevant. The students are asked to write not just the solution, but describe their thought process in categories corresponding to the typical stages of expert reasoning: qualitative analysis, identification of relevant concepts, ongoing monitoring (evaluation of the solution as it progresses), and validation of the solution obtained. The beauty of this system is that it not only guides the student into a more ‘expert’ mode, it also tracks the time spent at each step, the resources accessed, and so on.So, has this learning environment helped train a new generation of experts?The answer is yes, with some caveats. First, as with any group project it is hard to track which students are working and which ones are learning. Second, Ogilvie’s course presents only five such problems to the students. (There is still all the core material to get through, after all!)As for the results, there is some good news and some bad news.In the first problem of the course, students completed the ‘qualitative analysis’ section an average of ten minutes before completing the assignment. In the last problem, this section was completed about twenty minutes beforehand. Another encouraging point is that very few students wasted time reading all the available information in later problems. “Taken together, the student groups show some progression towards expert-like behavior” Ogilvie writes, “earlier qualitative analysis and more selective requests for information.” By the end of the course, students were also identifying the most relevant concepts earlier.In other words, the students grew more likely to think about the problem before attacking it. That’s the good news!The bad news is that there is no evidence for improvement in one of the most important aspects of expert reasoning: ongoing monitoring. Monitoring is a form of critical thinking, the general (and highly useful) cognitive skill of evaluating the quality of information. Experts in a field will examine their solutions repeatedly as they work them out. Have any of their initial assumptions been violated along the way? Is the solution making progress, or is it getting sidetracked? Is the math becoming simpler or more complicated? If an expert senses that a solution isn’t working well, they may abandon it to look for a better approach.In all fairness, this is also probably the most difficult skill to measure. Computer tracking can only show that students usually filled in the “monitoring” summary right before completing the assignment. No doubt this skill can be taught as well, but it might lie beyond the scope of computer instruction. I still vividly remember one of my professors taking only ten minutes to solve a physics problem that had taken me hours to work out. Perhaps the lesson of monitoring solutions can only be learned by sincerely regretting the time you just wasted.Note: 1groups.physics.umn.edu/physed/ … rch/CRP/crintro.htmlCitation: “Understanding Student Pathways in Context-rich Problems” by Pavlo Antonenko, John Jackman, Piyamart Kumsaikaew, Rahul Marathe, Dale Niederhauser, Craig Ogilvie, and Sarah Ryan is available online at xxx.arxiv.org/abs/physics/0701284By Ben Mathiesen, Copyright 2007 PhysOrg.com.

Citation: Can expert reasoning be taught? (2007, February 9) retrieved 18 August 2019 from https://phys.org/news/2007-02-expert-taught.html In addition to mastering a large body of knowledge, successful researchers must acquire a host of high-level cognitive skills: critical thinking, “framing” a problem, ongoing evaluation of the solution as it progresses, and ruthless validation of one’s final answer. Some students pick these skills up on their own as they advance towards their degree, especially those who participate in research, but they rarely appear in a curriculum. Students working on a context-rich problem fall naturally into two groups. Teams above the line demonstrate expert-like behavior, in that they completed their qualitative analysis of the problem before accessing the relevant information and submitting a solution. Those teams below the line demonstrate novice-like behavior, in that they appear to read through as many resources as they can before attempting a solution and submit their analysis of the problem only after a solution has been recognized. Credit: Craig Ogilvie Expert mathematicians stumped by simple subtractionscenter_img Explore further Professor Craig Ogilvie of Iowa State University has developed a problem-solving environment that not only encourages students to practice these skills but also monitors their progress.As a physics professor, I often find myself torn between competing educational goals. On the one hand, most courses have a laundry list of fundamental theories and techniques that must be taught if the students are to advance further in the subject. On the other hand, there are a number of higher cognitive skills that I would also like to emphasize. The cognitive skills are more useful in life, but how much subject matter can I reasonably sacrifice to make room for teaching them?Traditional teaching methods reinforce the course content by assigning busy work — practice makes perfect, after all. Homework assignments consist of simple “plug and chug” problems that students can solve easily by finding the appropriate formula. While such assignments do help students learn the main topics of a course and prepare for the inevitable final exam, they promote a very limited style of problem-solving. More importantly, they provide little motivation for students to absorb the lessons of scientific thought.One solution is to raise the bar on the problems. Why not strip them of their hand-holding language, and present information in a more realistic setting? The result may be too difficult for one student, but is probably suitable for a group of students. Researchers in physics education at the University of Minnesota, for example, have created an archive of such context-rich problems for their introductory physics courses1. Context-rich problems force students to practice some of the cognitive skills used by experts, in particular the skill of analyzing a problem qualitatively before looking for the proper formula.I don’t wish to bore my readers, so I will present the briefest possible example of this qualitative analysis. When confronted with a collision problem, students should ask themselves whether friction is an important factor before they look up Newton’s laws. Figuring out how a problem relates to known principles is the first step taken by experts when they approach a new situation. This document is subject to copyright.

Matter of choice

first_imgAt times we all feel that life is very complicated but only a few of us are able to express the dilemmas in right manner. Artist Aarti Zaveri expresses the same through her art work at upcoming United Art Fair. The artist believes that, it is very easy to complicate a beautiful life and at the same time very difficult to simplify the essence of life. These thoughts are reflected in her paintings by the use of bold and vibrant colours.  She has created a body of work around these figurative expressions. One can sense the attempt to convey her deep thoughts through the use of symbols and signs in a subtle and minimal manner in each painting. The canvas reflects the basic complexity of a human to find answers in the outside world when all the answers needed are already present within us.The last edition of her installations in United Art Fair, were based on the theme, how a person wears a mask to conceal various truths of life. Which was based on artistes belief that life is a paradox and a puzzle, the ones who solve it, makes it simple and the rest remains to be just a part of the puzzle.With her recent work she is giving out a beautifull message that everyone has an option to make their lives easy or difficult, it depends on us what we choose.last_img read more
