Few but those pursuing a health-related major know about the Emergency Medical Services of USC, a student organization comprised of emergency medical technicians that provides emergency pre-hospital care on and around campus.Since its founding in 2009, EMSC has been providing medical assistance at large events at USC, such as the Obama Rally, the Festival of Books, the Welcome Back Concert, graduation and football tailgates. EMSC is now looking to expand the range of events that they cover.Sean Neifert, the EMSC director, is working alongside Austin Churchill, the assistant director to the USG Wellness Affairs committee, to push a resolution that would increase EMSC’s reach.“We are looking at things like philanthropies and parties on the Row and other events on campus,” Neifert said. “We have a plan so that student organizations can contract with us directly instead of going to the administration, and then we can submit the forms to our adviser so that she can approve the events.”A similar proposal was made in March, but now Neifert is working on having all the details figured out.“It’s really the liability aspect,” Neifert said. “The administration has this view of us as student EMTs, when we’re really emergency medical technicians who also happen to be students. They think that our certification doesn’t mean as much, and they think we’re going to mess up when we’re on the field. I can tell you with confidence we’re not going to.”Neifert added that EMSC is not a replacement to the fire department but a valuable assistance in the moments before an ambulance arrives. He stated that the Department of Public Safety Emergency, which has no medical training other than CPR, will simply call the fire department and not provide emergency assistance in the meantime. Because most emergencies deal with intoxicated students, Neifert argues that the waiting gap can be crucial.DPS Deputy Chief David Carlisle said that all DPS officers receive first-aid and CPR training. In addition, some DPS officers have received EMT certification independently. Carlisle said that paramedics typically respond so quickly that it makes sense for DPS officers to wait until they arrive on the scene. He also said that DPS is starting combat medical training for officers so that they can provide more advanced care such as applying field dressings and tourniquets.Neifert, however, believes the response time is still too long.“The average response time for the fire department is six minutes, and in those six minutes a lot of stuff can happen,” Neifert said. “Six minutes of no oxygen to your brain, and you’re pretty much brain-dead.”Neifert, who also holds a job at a hospital in Orange County, explained how other universities have larger student EMT programs. He gave Johns Hopkins, Brown and UCLA as examples. The latter, for instance, has a 24/7-ambulance service completely staffed by students.“I think [UCLA] is a great model to go off of,” Neifert said. “I think, obviously, USC is definitely a different situation. It is a private school, we don’t have a hospital on campus as well, so those are definitely things we need to consider. But when you look at UCLA they really put trust in their students.”Neifert also mentioned that all members of EMSC take skills tests at the end of each semester and have training sessions twice a week. Such high amounts of training, Neifert argued, show the commitment and dedication of student EMTs. Because of this, the University has no reason not to bestow EMSC greater responsibilities.“Our administration is behind the times on how they view student safety and wellness in regards to this issue,” Neifert said. “The administration has to step up to the plate and contract with us.”Churchill, who is working closely with Neifert, explained how they plan to pursue the organization’s expansion.“What we want to do is ultimately pass a resolution in the coming weeks to show that the student body supports this,” Churchill said. “USG has a lot of direct contact with the administrators that we need to get this approved, such as DPS and Fire and Safety, there’s a lot of overlap between those that oversee EMSC and those that specifically the Wellness Affairs Committee works with.”Churchill mentioned that they could put more pressure on the administration by showing support not only from EMSC, but also from the entire student body.“This is a really important initiative for the student body, because there is that mean gap time which we have right now,” Churchill said. “Most of the transfers we have right now are alcohol-related. If we want to treat the students in the meantime, we need to expand this organization.”
With only six total picks, the Cowboys do not have much work to do in the 2019 NFL Draft. They will need to compensate for that limited quantity with great quality in their selections.Dallas essentially made Amari Cooper its first-round selection when it traded for the wide receiver last season. That move addressed the Cowboys’ biggest potential need in the draft, and they also are coming off a year in which they nailed their first-round pick, linebacker Leighton Vander Esch. Final thoughts:Jones does not get enough credit for being a strong talent evaluator in his own right to compliment his willingness to lean on a good scouting staff. The Cowboys have had five solid drafts in a row. Where he gets in trouble sometimes is taking too many risks with boom-or-bust talent after Round 1, some related to injuries or off-field issues. He tends to be well-tuned to his team needs, and lately, there haven’t been too many reaches.Should the Cowboys stick with a defense-heavy draft like their hauls in 2017, 2016 or 2015 in relation to what they need most now, they will be positioned to land at least three key rookie contributors. So what might Jerry Jones, Stephen Jones and Jason Garrett do starting in the middle of Day 2 of the 2019 NFL Draft? Here we lay out the Cowboys’ draft blueprint in more detail.SN’s NFL DRAFT HQ:Iyer’s mock draft | Live pick tracker | TV scheduleCowboys NFL Draft picksRoundPickSecondNo. 58ThirdNo. 90FourthNo. 128FourthNo. 136 (compensatory)FifthNo. 165SeventhNo. 241Cowboys’ NFL Draft team needsDefensive line: Tackle is the biggest hole. Tyrone Crawford has been productive, but he is entering his age-30 season and is in line for a suspension after an off-field incident. Antwaun Woods and Maliek Collins leave the position rather weak in the wake of David Irving’s retirement. At end, the team locked up Demarcus Lawrence, still has 2017 first-rounder Taco Charlton on the other side and traded for Robert Quinn. But there’s not much depth and limited pass-rush punch after Lawrence.Defensive back: The Cowboys didn’t do much to tap into the free-agent safety market, with only the more backup-level signing of George Iloka. They might think safety first, but they also need to find some subpackage help in the secondary.Outside linebacker: Vander Esch and Jaylon Smith will be together for a while as second-level studs, but Sean Lee is 32 and will see a fading role on a one-year restructured deal. With Damien Wilson gone, they need someone who can play the pass on the strong side.Wide receiver: Cooper and second-year man Michael Gallup will start outside, with free-agent addition Randall Cobb replacing free-agent departure Cole Beasley in the slot. But the Cowboys could add depth in the form of a speedy deep threat for the outside.Tight end: Jason Witten is back, but he essentially replaces Geoff Swaim, with neither Blake Jarwin nor Dalton Schultz looking like a long-term answer at the position.Running back: The Cowboys need a capable backup behind Ezekiel Elliott after not re-signing Rod Smith.Cowboys mock draft 2019Second-round plan:No. 58: Chauncey Gardner-Johnson, S, FloridaThis would be a great pick for Dallas in the second round, when several safeties should be coming off the board. The pick would be much like Houston getting Justin Reid in the third round last year — an immediate steal of a starter.Gardner-Johnson, at 5-11, 210 pounds, has ideal size for the position and is athletic enough to cause problems for both tight ends and slot receivers in coverage. He also is a good help defender downfield. He closes on the ball well, and his natural ball skills will fill a void for the Cowboys.MORE: Full NFL mock draft for 2019Second-guessing that plan:Given Gardner-Johnson’s recent rise, there’s a chance he might not last until that pick. In order, the best backup plans for safety are Alabama’s Deionte Thompson and Virginia’s Juan Thornhill. If all three are gone, then Maryland speedster Darnell Savage could also work in a defense to complement track star Byron Jones.The other position to which the Cowboys must pay attention early in the draft is defensive tackle. Should either Notre Dame’s Jerry Tillery or Ohio State’s Dre’Mont Jones last until their pick, they might need to go for some interior pass-rush upside built for their base 4-3.The biggest offensive temptation would be Ohio State’s Parris Campbell, the fastest wide receiver the class, to give the Cowboys some big-play ability for Dak Prescott. Don’t be surprised if …… the Cowboys trade down from No. 58 for more volume. Although that pick the sweet spot to address safety, Dallas sliding down in the round for an extra Day 3 pick and addressing the position a little later with Iowa’s Amani Hooker or Miami’s Jaquan Johnson could also be a smart play.The Cowboys have gotten used to operating with nine total picks, which has been the case for three consecutive drafts. The last time Dallas had only six picks, in 2010, it was able to land Dez Bryant in Round 1 and Sean Lee in Round 2. This year, however, is a bit different with no top-50 pick.Rest of Day 2 plan:If the Cowboys need to pass on safety in the second round, either Hooker or Johnson should be available at No. 90. But in the more likely event that they land neither Tillery nor Jones, then there are two 4-3 defensive linemen to consider in the third round.Both of them are natural ends from in-state schools: TCU’s L.J. Collier and Texas’ Charles Omenihu. Collier (6-2, 283 pounds) relies on power and toughness to disrupt plays in the backfield. Omenihu can hold up as a strong rotational lineman (6-5, 280 pounds) while he refines his pass-rush skills.The Cowboys also can’t forget about running back before Day 3, as two players from a neighboring state standing out: Oklahoma’s Rodney Anderson and Oklahoma State’s Justice Hill. Anderson (6-0, 224 pounds) has an interesting combination of downfield thumping and open-field elusiveness. Hill (5-10, 198 pounds) is a scrappy, relentless back who pushes to find every extra crease and yard. Either would make for high-end insurance for Elliott.Day 3 sleeper:Cameron Smith, LB, USCThere are plenty of strong run-stopping linebackers to consider in this draft, but the Cowboys can focus more on a complementary player to Vander Esch and Jaylon Smith. Cameron Smith does not fly around as well as faster players at the position, but his experience and instincts help him compensate, especially against the pass. He reads the field well and is assignment-sound to the point where he is just as comfortable in the open field as he is in tight quarters. Smith would round out one of the NFL’s best second-level defensive units.MORE: Can you name the Cowboys’s worst-ever NFL Draft pick?
DES MOINES — The Republican-led Iowa Legislature has again endorsed a proposed gun rights amendment to Iowa’s constitution. Senator Brad Zaun, a Republican from Urbandale, said the amendment’s “strong language” is necessary “in case of laws coming out of D.C. or in case of any court decisions that would weaken our Second Amendment rights.”Senator Tony Bisignano, a Democrat from Des Moines, was among those who suggested that if voters approve the amendment, it could lead to the repeal of current gun-related laws.“Just say it. You don’t want any laws when it comes to guns and arms and ammunition and restrictions,” Bisignano said during Senate debate. “You don’t even want training.”Legislators had discussed this same proposal before and had hoped to place the issue before voters in 2020, but the Secretary of State failed to meet a publishing deadline last fall, so the process has been restarted. 2022 is the earliest Iowa voters could decide whether to add the amendment to the state constitution.Senator Zach Whiting, a Republican from Spirit Lake, noted a number of gun rights activists were at the capitol yesterday, lobbying for it.“This constitutional amendment, if adopted by the people, is the single most important thing that we can do for the Second Amendment in the state of Iowa,” Whiting said.Senator Claire Celsi, a Democrat from Des Moines, was a “no” on the proposal.“I’m here representing one of the 90 percent of Americans who say they want universal background checks,” she said. “Those are the kind of laws that would keep guns out of the hands of those who have no business possessing a gun.”Celsi went on Twitter to announce she had asked that security officers be dispatched to the balcony overlooking the senate, as she said supporters of the amendment sitting in the gallery were giving her “dirty looks” and she was “fully aware that most of them are carrying guns.”The Senate approved the gun-rights proposal early yesterday afternoon on a 33-to-16 vote. The House took up the issue, too, and passed it last night by a narrower, 53-to-46 margin.
Mo’unga converted and added a second after Beauden Barrett scampered over after a neat Aaron Smith drop-off that left Wales prop Dillon Lewis prone.A sustained period of Welsh pressure then followed and paid off after Patchell found Hallam Amos with a long miss-pass, the full-back dummying Mo’unga and shooting over for a try.Patchell added the conversion and then a simple penalty, but New Zealand roared back through veteran Ben Smith, the winger jinking his way through a crowded defence after good lead-up work by Read and Liam Coltman.Smith, 33, got his double on the stroke of half-time, taking a long pass from his namesake Aaron and powerfully handing off Tomos Williams to slide into the corner.Mo’unga added the extras to leave New Zealand in complete control at 28-10 at half-time.The cut-and-thrust, running rugby continued in the second period, Ben Smith surging deep into Welsh territory before Sonny Bill Williams provided a perfect offload for centre partner Ryan Crotty to cross for the try.Both sides were much different from their semi-final line-ups, Hansen having made seven changes to the team which lost 19-7 to England and Gatland nine from the side that went down 19-16 to South Africa.One ever-present on the team list for Wales, however, has been Josh Adams, and the winger burrowed over from close range for a seventh try of the tournament to usurp Shane Williams’ Welsh record of at a World Cup.The game becamse increasingly error-strewn, but Mo’unga stepped through Dan Biggar’s poor tackle for a late try, taking his personal tally to 15 points.Share on: WhatsApp All Blacks defeat Wales 40-17 to clinch the Bronze medals at 2019 Rugby World Cup. PHOTO via @AllBlacksTokyo, Japan | AFP | Veteran winger Ben Smith scored a classy try double as New Zealand beat Wales 40-17 to clinch third spot at the Rugby World Cup on Friday in the perfect send-off for storied coach Steve Hansen.In what was the final Test for both Hansen and Wales counterpart Warren Gatland, after seven and 12 years at their respective helms, both sides produced an entertaining encounter that saw New Zealand outscore the Welsh by six tries to two.The result means New Zealand have won 32 of their 35 meetings with Wales, last losing in 1953, while Hansen’s incredible record includes just 10 defeats in 107 Tests in charge.“It was just important we come back and honoured the jersey and our fans and get over the disappointment of last week,” said Hansen, referring to the semi-final defeat by England.“Tough old game for both sides and just want to congratulate Wales too because I know they’ll be feeling a bit at the moment.”Gatland, under whose charge Wales have won 85 of their 151 Tests — but have lost all 12 matches against his native New Zealand — might have joked that it would have been better to settle the play-off by a drinking game, but both teams showed intent on the pitch.“Our boys never gave up and kept trying to play some good rugby in the second half. Probably a game too far for us really,” said the New Zealander, who will now coach the Waikato Chiefs.“I’ve loved my time in Wales. People have been amazing and incredibly welcoming. But that era’s over now and I’m excited about the next challenge going back to New Zealand and being involved with the Chiefs.”– Running rugby –Richie Mo’unga missed an early penalty, but that was merely a blip as the All Blacks looked to run the ball at every opportunity at a packed Tokyo Stadium.The first try came quickly, the influential Aaron Smith finding skipper Kieran Read, who offloaded to Brodie Retallick, the lock stepping inside Rhys Patchell and producing a brilliant backhanded pass to Joe Moody, the prop bounding in from 20 metres for a great front rower’s try.

This may be the last evidence needed to debunk the image of Neanderthals as dim-witted brutes: they wore make-up. The BBC News reported the discovery of their cosmetics containers: seashells with pigments kept for the purpose of improving their self-image. If that is not a human characteristic, what else is? The shells contained complex recipes of pigments. There were also painted shells apparently used as jewelry. “The team says its find buries ‘the view of Neanderthals as half-wits’ and shows they were capable of symbolic thinking,” the article said. What’s more, according to the dating scheme, this evidence existed 10,000 years before contact with modern humans. Study leader Joao Zilhao [Bristol U, UK] said, “The association of these findings with Neanderthals is rock-solid and people have to draw the associations and bury this view of Neanderthals as half-wits.” Chris Stringer of London’s National History Museum agreed that this evidence appears to disprove the Neanderthal = Dimwit equation – but it just adds to growing evidence over the last decade. “It’s very difficult to dislodge the brutish image from popular thinking,” he lamented. PhysOrg reported more on this story, describing the pigments and the shells that were found, and evidence why they could not be attributed to other modern humans. It seems that the final distinction between Neanderthal and modern human behavior has been falsified: “This is significant because until now the practice of body ornamentation has been widely accepted by archaeologists as evidence for modern behaviour and symbolic thinking in early modern humans and not Neanderthals.” New Scientist commented, “Add this to other recent evidence that Neanderthals hunted, painted and perhaps even spoke like anatomically modern humans, and the dumb caveman hypothesis becomes even more untenable.”So why does the BBC News include an artist rendition of a brutish-looking Neanderthal with the article? Talk about perpetuating a myth. They should have posted a Neanderthal version of Paris Hilton in the Cave Beauty Pageant. You can put lipstick on a Neanderthal, but it’s still a human being. This shows the damage that visualization can do with the power of suggestion. Once an image gets implanted in the public consciousness, and the name associated with it becomes associated with less-evolved, it’s very difficult to dislodge, as Stringer said. This myth has gone on for decades – for over a hundred years! Think of all the damage this myth has done. Students have been misled in textbook portrayals of our Neanderthal brethren, presenting them as less than human. It’s historical racism. If Neanderthals were with us today, boy would they be mad. Undoubtedly they would form an Association for the Advancement of Neanderthal People and seek court injunctions against discrimination. We need to pay reparations. We should rehabilitate our Neanderthal brethren by promoting good looks, strength and intelligence in our portrayals of them, much like Polish were rehabilitated through their Solidarity Movement after years of being the butt of Polack jokes. What can you do to help the Neanderthal Wannabee movement? If nothing else, help stop the evolutionary paleontologists from committing this sin again the next time they try foisting a sub-human transitional form on the media.(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0

A stone tool attached to a wooden shaftwith adhesive made from red ochre no.15 and A. karroo gum.(Image: Wits University)Janine ErasmusFind out more about using MediaClubSouthAfrica.com materialThe Middle Stone Age site of Sibudu Cave, situated about 40km north of Durban, KwaZulu-Natal, has once again yielded important archaeological information. Researchers have identified a compound adhesive that was manufactured about 70 000 years ago and used to make hunting weapons.In 2008 the cave was the site of the discovery of three bone implements that were subsequently dated to about 60 000 years ago. The discovery was significant in that it would likely establish the origin of bow and bone arrow technology as occurring at least 20 000 years earlier than originally thought.Researchers from Wits University’s archaeology department have now revealed the discovery of a form of glue used by previous inhabitants of the cave, which was first excavated in 1983 and continues to be excavated under the current direction of Professor Lyn Wadley.Two of Wadley’s colleagues, residue analysts Bonny Williamson and Marlize Lombard, found traces of acacia gum, and an accompanying red ochre pigment initially suspected to be merely decorative, on stone tools found inside Sibudu Cave. The ochre was only present on tools fastened to wooden shafts to make composite tools.Acacia gum, also known as gum arabic, is a natural product exuded from acacia trees to seal holes in the bark. It is harvested from various acacia species using different methods, either by deliberately cutting holes in the trunk to stimulate gum production, or collecting from natural cracks in the bark.The team’s findings were published in May 2009 in the Proceedings of the National Academy of Sciences. The article is titled Implications for complex cognition from the hafting of tools with compound adhesives in the Middle Stone Age, South Africa and is authored by Lyn Wadley, Tamaryn Hodgskiss and Michael Grant of Wits University.In the paper the researchers described the ancient cave dwellers as “competent chemists, alchemists and pyrotechnologists” who knew exactly how to manipulate their ingredients and deliberately bring about the physical changes necessary to produce an effective adhesive.A significant achievementWhile symbolic art is the internationally accepted anthropological criterion for mental capability, the team says the manufacture of the glue was as significant an achievement and shows that Stone Age people possessed much greater cognition and intelligence than originally thought.They propose that the result of their research is a fresh way of recognising and measuring cognitive ability.The Sibudu tools were constructed around the same time as the oldest known examples of abstract art, found in Middle Stone Age layers in Blombos Cave on the southern coast of South Africa, about 290km east of Cape Town.The 70 000-year-old artwork is inscribed on two pieces of ochre. Blombos is also famous for the discovery of 75 000-year-old shell beads and bone tools made 80 000 years ago.Opinions differ as to the significance of the artwork, with some experts saying that it may have been merely meaningless engravings, and others now arguing that the manufacture of a rather complex glue is a more convincing display of intelligence.Skilled artisansThe Wits research team believes that ancient Stone Age artisans were remarkably skilled and thoroughly understood the properties of their ingredients. They used acacia gum to bond stone and wood but the method of attachment showed considerable ingenuity, as the team were unable to successfully duplicate the process using just acacia gum. They had to dig deeper for the answer.In Stone Age times it was crucial to have effective hunting weapons, as lives were at stake. Although Wadley and her colleagues used the same methods and natural ingredients that would have been available to Stone Age dwellers, their versions of composite tools were not always as successful in stringent physical tests such as wood-chopping.The team found that the addition of the ochre pigment produced a more robust glue that held the tools together for longer, but the manufacturing process was intricate and required careful attention.It took some experimentation to hit on the right formulation. For instance, the fire had to be kept at the correct temperature, the control of which depended on the type of wood used. The glue could not be mixed too close to the flames or it would boil, resulting in trapped air bubbles that weakened it.Laboratory tests established that the use of ochre causes a rise in the pH of the glue, making it less acidic. It also affects the electrostatic forces present and results in a physical change in the malleability of the substance.A mixed particle size was important to the success of the compound adhesive. The greatest success was achieved using red ochre number 15, as this resulted in bigger grains which were comparable to stone chips in concrete. However, ancient artisans may also have added an aggregate in the form of grains of sand to ensure a more consistent product.The team’s own experimentation showed that in contrast with other living creatures, such as some birds or wasps, that make composite glues out of instinct, the process of constructing a finished hunting weapon required the ability to multi-task in order to keep track of the various steps.“Some of the steps required for making compound adhesive seem impossible without abstract thought and the ability to multi-task,” they wrote. “This suggests overlap between the mental abilities of modern people and people in the Middle Stone Age.”Do you have queries or comments about this article?
