first_imgMany strands of Shujaat Bukhari’s murder in Srinagar on Thursday resemble those of the assassination of People’s Conference leader Abdul Ghani Lone 16 years ago.It is so despite the fact that Bukhari was a journalist and Lone a politician, both high-profile. Both were perceived to be seeking to bridge the mutually clashing political ideologies comprising the complex Kashmir matrix.Retrospectively, it would seem that first Lone and then Bukhari made a fatal miscalculation. Any attempt at crossing the red lines, even with pious intention, amounts to walking into a minefield because elements in Pakistan view it as a hostile act.Extremist factions of Kashmir-oriented armed insurgent groups based in Pakistan are overly suspicious of individuals as well as groups, on both sides of the Line of Control, which are perceived to be propelling any proposition seeking freezing of status quo on Kashmir between India and Pakistan as a way out of the impasse. They would settle for nothing short of whole of Jammu and Kashmir.As it is, almost each and every peace move crashes right at that ideological barrier.Bukhari’s profile did not take long to emerge on the Kashmir scene after he opted for journalism in the 1990s when he joined Ved Bhasin’s Kashmir Times in the thick of insurgency (then spearheaded by pro-Independence Jammu and Kashmir Liberation Front). Bukhari’s shifting to The Hindu a few years later substantially elevated his public profile. He was an instinctive journalist and his wider interests buttressed his public image. Bukhari widened his sphere of influence with the help of his talent and aptitude for Kashmir’s cultural and literal life. He soon became a popular face in the Kashmir media and in the rest of India and Pakistan as he engaged in Track Two activities.His visits to Pakistan, the U.S. and European countries got wide publicity in his own English daily, Rising Kashmir, which he floated after leaving The Hindu. In less than 10 years, his stable expanded with the addition of an Urdu daily, Buland Kashmir, a Kashmiri daily and an Urdu weekly. Bukhari took time off to promote literary and cultural fora floated by his group of publications.There was nothing he or his products — newspapers and literary and cultural fora — did or say that could place him in the hazardous course of confrontation with any of the local militant or secessionist groups.To his credit, he gave sufficient coverage to every thought and idea afloat in the over-crowded Kashmir politics.Bukhari soon became a familiar and popular face in debates on Kashmir on national TV channels. He held his ground against vocal opposition from ultra nationalists, just as he sought to deal with hardcore local armed groups without yielding any ground to them or risking their annoyance.His publications appeared with a distinct anti-establishment edge, but stopped short of crossing the red line of accession.Somehow, Bukhari was not able to maintain harmonious relationship with the local press corps. He recently fell out with the main body and floated a parallel one, though hardly with any big name.Reports from across the LoC published here lately indicated that Bukhari’s venturing into Track Two activities was causing resentment in the pro-establishment militants in Pakistan. They questioned his bona fides in the context of his recent meetings held in the U.S., Turkey and Dubai.Nobody could have guessed the impending tragedy. Bukhari had come to be seen as one of the few effective, reasonable voices of Kashmir. Ironically, its ugly side became the perceived cause of his tragic end.(The writer is a veteran Srinagar-based journalist)last_img read more

first_img Consultant Cardiologist at the Heart Foundation of Jamaica, Dr. Handel Emery, has highlighted the need for more resources to address cardiovascular complications, which account for the majority of diabetes-related deaths.Dr. Emery was speaking at a JIS ‘Think Tank’, on January 23, against the background of the observation of Heart Month, under the theme ‘The Diabetic Heart: Are you at Risk?’.“I think it is of paramount importance that we recognise this connection, and direct a lot of our attention to identifying, preventing and treating the cardiovascular complications associated with diabetes,” he emphasised.Dr. Emery said it is important to note that diabetes is extremely common, pointing out that the current data suggest that about 12 per cent of the population over the age of 15 in Jamaica is diabetic.“When you look at the international data, it’s even more alarming,” he noted. The Consultant said that about 400 million persons worldwide are diabetic at present, and the number is expected to grow to about half a billion by 2030.“It is a significant global problem, and whilst there has been a lot of focus given to some of the other complications of diabetes, we tend not to really focus a great deal of effort, energy and resources on the cardiovascular complications associated with it,” Dr. Emery said.He noted that the relationship between diabetes and hypertension is not new, and although the initial accounts were largely anecdotal, “we began to have epidemiologic data which support this association in the form of a very large and important trial called the Framingham Heart Study, which began in 1948”.The Consultant explained that subjects were assessed over a 30-year period, which led to the establishment of associations between particular disease entities.“One of the associations made from the study was that persons who were diabetic were about 200-500 per cent more likely to develop cardiovascular disease than persons who were not diabetic,” he informed.Dr. Emery noted that diabetic persons have a more rapid rate at which fat and cholesterol are deposited in the arterial system, leading to a narrowing of the blood vessels, which limits the flow of blood. This results in the heart muscle being starved of blood, which can lead to angina.He also explained that one may have complete blockage of the vessel, which is a heart attack.“Another way in which diabetes leads to heart failure is that the elevated blood sugars which we see in diabetes can also be directly toxic to heart cells. The heart tissue is not meant to function in an environment where blood sugars are elevated, so if they are chronically exposed to those levels of blood sugar, then there are biochemical consequences such as weakness of the heart muscle, and many patients go on to develop heart failure,” he said. “I think it is of paramount importance that we recognise this connection, and direct a lot of our attention to identifying, preventing and treating the cardiovascular complications associated with diabetes,” he emphasised.

first_imgMONTREAL – Bombardier’s strategic C Series partnership with Airbus should put it on stronger financial footing but it remains unclear what fate awaits its other commercial aircraft.The Montreal-based transportation company remains burdened by more than US$9 billion of debt and wants to regain its leading position in the high-margin business jet market.That starts with completing the Global 7000 next year followed by the Global 8000 aircraft. A complete overhaul of the Challenger 650 is seen as the next big investment.So where does that leave the Q400 turboprop and aging CRJ regional jets?That’s the question on everyone’s minds, says Chris Murray of AltaCorp Capital.He doesn’t foresee the company coming up with a new CRJ design, but it may choose to add new engines to make the plane more competitive with Embraer’s new E2 jets.“I don’t think that I’m expecting the program to fall apart… but at the same time I’m not expecting there to be this massive resurgence of regional jet orders or turbprop orders,” he said in an interview.Bombardier (TSX:BBD.B) said it’s committed to the Q400 — which recently secured its largest order, from India’s Spicejet — and CRJs.“We like these products, they give us critical mass,” CEO Alain Bellemare said Friday after introducing the Airbus CEO to Montreal’s business leaders.Bombardier Commercial Aerospace president Fred Cromer added that the partnership with Airbus strengthens its entire civil aircraft portfolio.“I think commercial aerospace has a home in Montreal and certainly in Quebec for a very long time,” he said in an interview.However, Cromer said that it’s premature to disclose what it will do to rejuvenate the planes.“At the right time we’ll talk about what the real long-term future is.”Rolland Vincent, an aviation consultant who previously worked at Bombardier, believes the transportation company won’t spend the large sums required to overhaul the regional aircraft programs as long as oil prices remain low.“I don’t think they make a lot of money on these aircraft so … as long as oil stays at $50 or thereabouts there’s probably a very limited business case for re-engines,” he said in an interview.Vincent believes Bombardier is no longer enamoured with the low-margin parts of its commercial aerospace business and will follow its historical pattern.“They fall in love with new technology, new markets and then after a while they kind of move along to something else and it’s a pattern that leaves a lot of debris behind.”Vincent worked on strategy at Bombardier during the period in the 1990s when it shook up the global aviation market by launching small regional jets that spawned new competitors like Brazil’s Embraer.He sees Bombardier eventually selling the Q400 turboprop and CRJ jet programs, possibly to China.The Chinese could be potential buyers, but they would prefer new technology, especially new generations of engines, added Ernie Arvai, partner in commercial aviation consultancy Air Insight.He doesn’t see a lot of buyers for the regional aircraft. Airbus already owns a large stake in ATR and Boeing has shown no interest in getting into smaller planes.U.S. scope clauses that limit the size of planes pilots can fly under their union contracts give the CRJ a five-year runway to secure orders, said Arvai.While the Q400 is “solid,” he doubts Bombardier will redesign the CRJ, which will be at the end of its life in about a decade.“It might be a natural winding down point,” he said.Union representative Dave Chartrand said employees are concerned because of the thousands of jobs in Toronto and Montreal that depend on the two programs.“Employees wonder and say what’s the next step, where are we going from here. I wonder also, but there are too many factors for us to have an answer tomorrow morning.”last_img read more

first_imgMumbai: In a clear indication of lack of support from the lenders on further funding, Jet Airways chief executive Vinay Dube has said it is painful that there is no commitment on the part of the all stakeholders on paying salaries to the employees which are due in a few days. The now grounded airline has not paid March salaries to its over 20,000 employees. Jet ceased operations on April 17. April salary is due in a few days. The airline suspended operations after the SBI-led consortium of lenders rejected its demand for a Rs 983-crore lifeline to help carry out operations and pay to the employees their March salaries. Also Read – Thermal coal import may surpass 200 MT this fiscal”While we will continue to support the bank’s bid find a buyer or the airline, it pains us to communicate that no clarity or commitment on salaries has been provided by any of our stakeholders so far,” Dube said in a communication to employees Friday.

He also said though there have been many board meeting, the promoters and strategic shareholder (Etihad) there was no favourable outcome on funding and paying salaries so far. “We have also approached government at the highest levels seeking intervention and assistance but that too has not yielded any positive results,” he added. Dube also said in the past few days the leadership team is trying to convince the lenders to release some funds to the employees, while continuing to support the bank led bid sale process. “We have told them repeatedly that our employees are facing grave hardships owing to non-payment of salaries and that if this were to continue any longer, our employees will have no option but to find employment elsewhere. “Unfortunately, the banks have said they are unable to make any salary commitments, until after the bidding process is complete,” he said.last_img read more

Dylan Moses, an eighth-grader from Baton Rouge, La., must be an amazing talent, for the middle-schooler received a scholarship offer from the No. 1 program in the country, Alabama.The 2017 running back prospect also was offered a scholarship by LSU last summer. He and his father, Edward Moses Jr., visited the Crimson Tide campus, and the 6-foot-1, 215-pound Moses was impressed.“For Dylan, excitement spilled over,” Moses Jr. said to ESPN. “When he heard those words from coach (Nick) Saban, ‘We’re offering you,’ you could see him light up. It was shocking because we were going in thinking we were just going to get a tour of what Alabama has to offer.“To hear, ‘You’re impressive, keep your grades up, we want you to come here, and we’re offering you a scholarship now,’ I can’t even put that into words.”It’s not the first time Alabama has offered a scholarship to a younger recruit, and it doesn’t happen very often.The Tide offered current 2013 signee Tim Williams as well as 2014 ESPN Watch List running back Leonard Fournette scholarships when they were both freshmen.Still, Moses might be the first eighth-grader to receive an Alabama offer. Other schools haven’t started showing interest yet, but his father anticipates things to pick up in the spring and summer. For now, Alabama and LSU have the early advantage.“The battle for Dylan internally is who would be the best fit,” Moses Jr. said. “Right now, he’s an eighth-grader, he doesn’t have to worry about that.“We have LSU right here. They have access to us. At Alabama, we know what they have over there with the great running backs and another first-rounder on the way. Those two schools are No. 1, and everybody else is 2, 3, 4 and 5.”The offer from the Tide and the earlier offer from LSU has the 2017 phenom on top of the world, but his father knows it’s his job to keep him grounded through the recruiting process. After all, he still has four years before he signs his national letter of intent.“The attention from those levels of institutions, No. 1 and No. 2 in the SEC and arguably in the country, he feels like a boss, like he’s untouchable,” Moses Jr. said. “We have to bring him back on down to earth, let him know that he still has to do his work down here to make sure that dream comes true.” read more

OSU redshirt sophomore safety Malik Hooker (24) returns his second interception of the day during the second half of Buckeyes’ season opener on Sept. 3 at Ohio Stadium. The Buckeyes won 77-10. Credit: Alexa Mavrogianis | Photo EditorListed as a starting safety for Ohio State on Saturday and donning a scarlet No. 24 jersey, redshirt sophomore safety Malik Hooker made his first impression in front of a crowd of 107,193 in Ohio Stadium.OSU coach Urban Meyer called him a “freakish” athlete, which showed on Saturday, midway through the first half.Hooker sprinted over to the opposing team’s sideline with redshirt freshman Damon Arnette defending Bowling Green senior wide receiver Ronnie Moore. Hooker jumped off of one foot, tipped the ball with his right hand and came down with the interception — which was one of the highlights of the first weekend of college football.Hooker displayed his “ball hawk” mentality again when he snatched his second interception of the day.But Hooker’s path to the centerfold of Meyer’s secondary was an unorthodox one filled with adversity, and he has his mom to thank for that.Hooker was a basketball star at New Castle High School in Pennsylvania where he was named to the Pittsburgh Post-Gazette’s Fabulous Five basketball team in 2012-2013. Hooker’s team was 54-2 combined in his sophomore and junior seasons in high school.He was a rising high school prospect sought by Division I schools, but when he entered his junior year, he returned to the game of football — one he had not played since suffering a shoulder injury in seventh grade.Hooker’s talent on the hardwood translated almost immediately to the gridiron as he was rated as a four-star prospect and the No. 26 athlete overall by 247Sports. Meyer said when he was recruiting him, Hooker scored 35 points in a basketball game his junior season.When Hooker arrived on campus in 2014, he had to take a redshirt and sit out a year. At the time, it wasn’t a situation Hooker was familiar with.“There were a couple times where I thought this wasn’t for me.” Hooker said. “I just started doubting myself because I felt like I didn’t fit in.”Hooker said he had several talks with his mom, Angela Dennis, while he was going through his redshirt season.“I don’t know what you’re going to do, but you’re not coming home,” Hooker said Dennis told him.Although Hooker said he was just blowing smoke at the time, in hindsight, he’s thankful for his mother’s advice.“My mom, she’s like my everything. Growing up, that’s all I had,” he said. “I learned a lot from my mom. Being a single parent, she taught me that no matter what you’re going through, just fight through what you’re doing, because there is going to be adversity.”Meyer estimates that between 95 and 99 percent of freshmen in college football experience what Hooker went through when redshirting. He said that Dennis is someone he should thank for encouraging Hooker to stay with the Buckeyes.Now, Meyer is reaping the rewards.Hooker said he gained his confidence when he saw results in the weight room. He said he began to see his body transform into the role he was expected to fill. He said he studied more film, learned the playbook and earned the trust of his teammates and his coaching staff.Hooker’s performance against the Falcons might have been the peak of a grind that started with doubt and culminated with his first two interceptions for the Scarlet and Gray.“I feel like my redshirt year definitely helped me fit into the environment more,” he said. “It definitely helped me bulk my body up and play out there with the Big Ten conference.”Hooker believes that a redshirt year can be taken one of two ways. The player can take it and get frustrated, or he can put the work into fine-tuning his game and benefit from a full year of development.Hooker will be asked to do more on Saturday at 3:30 p.m. at the ‘Shoe against a prolific passing team in Tulsa. However, Meyer believes in Hooker’s basketball and athletic background to lead the OSU defense.“He can do whatever he trains to do. He’s talented. He’s fast. He has great ball skills,” Meyer said following the team’s 77-10 victory over Bowling Green. “His commitment to our program now is over the top.” read more

With the Ohio State women’s basketball team on the verge of missing its first NCAA tournament berth since coach Jim Foster’s arrival in 2002, the possibility of coming up short is starting to sink in for the Buckeyes. However, it’s not the possible absence from the tourney that has shaken the team most, but rather the coming to terms with losing its star senior guard, Tayler Hill, at the conclusion of this season. Hill is averaging 21.1 points per game, which leads all scorers in the Big Ten. “I think (Hill) deserves to be one of the best players in the country despite the team’s record this year,” said Ohio State redshirt senior guard Amber Stokes. The Buckeyes (14-10, 4-7 Big Ten) have been plagued by illnesses and injuries all season long, which are partly to blame for the 4-7 record in conference play. Yet even in times of trial, Hill’s performance on the court has rarely faltered. Following a 68-45 win against Indiana on Jan. 17, Foster said “Hill didn’t have her legs,” from being ill in the days before the game. Hill, though, still managed to keep Hoosiers’ standout senior forward Aulani Sinclair to five points on 2-for-15 shooting. “She is a hard worker and will do anything it takes to help this team to be successful,” Stokes said. Hill’s hard work and dedication to the game can be traced back to her basketball days at South High School in Minneapolis, Minn. Hill ended her four-year varsity career as Minnesota’s all-time leading scorer (boy or girl) with 3,888 points. After graduating from OSU, Hill said she wants to play in the WNBA and play basketball overseas. Foster said he believes Hill is going to be a high draft choice. “She’s a very good defensive player,” Foster said. “I think her versatility really makes her a valuable attribute. She can score, she can play the point, and she can play from the perimeter … All those things are a big deal to a coach.” While Hill said she would love to play on any team in the WNBA, she would prefer to play in Minnesota. “Playing at home would be great because of family,” Hill said. Hill’s native WNBA team, the Minnesota Lynx, are regarded as one of the top teams in the league, especially with the recent addition of former Connecticut standout Maya Moore. The Buckeyes, though, will likely have big shoes to fill with the loss of Hill. But Foster is assured that the offseason will serve as an opportunity to get better. “There are a number of candidates that are going to play for that position,” Foster said. After losing to Nebraska, 58-39, Thursday night in Lincoln, Neb., the Buckeyes are set to play Minnesota Feb. 21 at the Schottenstein Center. read more

first_img For us, that’s a challenge. If The New York Times Magazine is putting Nicki Minaj on its cover or T Magazine is putting Rihanna on its cover during the same cycle as us, we want to make sure that the way we’re covering that story is innovative, unique and high quality. For us, having Rihanna on our cover at the same time as Vanity Fair and T Magazine, I feel like our story really held up. That’s what this year has been about for us, challenging ourselves not to just be a good music magazine or a good looking magazine, but to be one of the best culture magazines out there.  Folio: There was a time when a huge, global pop star like Rihanna might have only wanted to appear on the cover of Vanity Fair, for example, and it seems that’s no longer the case. Is that reflective of a changing landscape in magazine media? Folio: Going back to the digital growth—where are you seeing all this new traffic coming in from? Folio: For starters, to what do you attribute all of this growth in digital? Is there anything you’ve been doing differently? Some of our biggest stories in the past year have absolutely been magazine stories. We had an amazing run with Fader 100 where we had two incredible cover stories, but also just a ton of excellent content that we created for the magazine that’s all done really well online. We had an exciting cover story with Zayn Malik, which for The Fader was kind of a departure, but also super in line with the history of the best stuff The Fader does, which is to talk to an artist early on in a project and take time to learn where their head is at. That Zayn story was a classic Fader story, and we were happy to bring the Fader approach to a new audience with that one. For music and culture magazine The Fader, the end of 2015 saw the release of the brand’s landmark 100th issue, the digitization of its complete archive through a partnership with BitTorrent, and unprecedented digital growth. Combined traffic across desktop and mobile jumped 33 percent year-over-year, and October 2015, the month the 100th issue was released, was the highest-traffic month in the magazine’s sixteen-year history. Our goal has been to move away from that MP3 blog model. We saw so much potential in The Fader’s brand and the way that The Fader has always looked at music, which is using music as a prism to learn more about the entire world and youth culture and technology. It’s been a process both of staffing up and working with everyone here to improve day-to-day writing and editing skills. We’re still a small staff and we will lean on each other to create most of the content. To some extent, we’ve just been in blogging boot camp all together, and trying to do magazine-quality stuff every day. Folio: caught up with Naomi Zeichner, editor-in-chief, to get a glimpse of what’s behind The Fader’s growth and what’s next for the brand. Folio: Looking back at that Fader 100 issue, was featuring well-established stars like Drake or Rihanna a departure for the brand? Naomi Zeichner: We’ve been doing everything differently over the past year or so. I don’t mean to say we’ve switched our entire approach or model, but The Fader at its inception and for many years on the internet was a great MP3 blog; that was the bread and butter of our business, and then we had this separate magazine that we were doing, and those stories would also always go online, but there were only so many of them. Zeichner: The Fader has always been all about balance. I don’t think The Fader has ever shied away from pop music. Drake and Rihanna are both established artists, but also artists who constantly have their hands in what’s next in culture and are supporting or feeding off of young artists, so they’re very much in our world. It was about looking back, but we also think those artists are really vital and interesting right now. It was the same for Zayn; Zayn was a pop star who was actively trying to wheel himself back into a smaller, more meaningful world. We thought that was an interesting story and it says a lot about the status of the boundaries between indie and pop. Zeichner: Yes, we have each issue up for free download as part of our bundle now, and then you’ll be able to purchase the entire archive. I went to an art show recently where these kids had created a whole wall out of Fader photography that they got from the archive bundle when it was free, and that was a really cool moment for me. Some of our early magazines still exist in this office only on compact discs as quark files, so knowing that the archive was digitized and made available is really amazing. Zeichner: This year, we have a fuller stable of editors than ever. A joke that I make with my deputy is that we taught each other “folk journalism.” We aren’t people who went to journalism school, but all of a sudden we have this infusion of people who have worked at amazing places and are some of the best editors in the business. Their specialties aren’t only in music. They’re people who love music and love culture, but also are really ambitious writers about politics, sports, technology, identity—things like that. I’m looking forward to those editors both improving the overall quality of our magazine stories and also making sure that we have more non-music, high-quality stories that we’re breaking in our magazine, as well as just bringing in more freelancers and more people into the Fader network. Folio: Your BitTorrent partnership resulted in over one million downloads for the Fader 100 issue. Can we expect more promotions like that in the future? Zeichner: Not exactly, but we are thinking about how to use social platforms for native content. These days, when an artist visits the office, what we’re doing with them for our Snapchat story is one of the first things we think about. A few years ago when we did our redesign for our site, we built it mobile-first, and we’re going to introduce a couple of tweaks to the mobile design in a couple weeks, making sure that all of our articles—whether it’s a long-form magazine article or something that’s more newsy or more listy—is really pleasant to read on your phone, and that you’re able to easily navigate around the day’s content on your phone. That sort of user experience is really important to us, but we aren’t necessarily tailoring content towards social. Folio: What are some ways in which that affects your editorial strategy? Are you tailoring content for different social platforms? Zeichner: Just like other publishers, we’re seeing a ton of traffic directly from Facebok. For us, I would say Twitter is a larger audience than for some other publications, I think because music readers still hang out on Twitter, which is awesome. We’ve seen a huge increase in mobile traffic. We also see a lot of direct traffic, which is coming from people texting each other links, or when people put links in their Instagram bios, which for us is an exciting metric. Folio: So what’s next? How will you top those numbers in 2016? Zeichner: Absolutely. I think a print magazine cover at this point is such a feather in the hat. There are so few print magazine covers, and we’re just really proud that people still feel that a Fader cover, as a symbol, is a currency that they want to be a part of, and that it still means something. These distinctions between a high-brow thing and a low-brow thing, or a popular thing and an underground thing, might go away. Lots of publications are now operating with that understanding. Last year we saw huge traffic growth when we were able to meaningfully weigh in on a cultural moment. When Meek Mill and Drake were fighting, we had a million posts that were different from posts that you’d see elsewhere on the internet, and that’s where we really saw growth. Looking at things like the election, and even the Grammy’s coming up, we want to make sure that we have the best coverage and all different types of coverage. Now we have coverage coming from our UK office, and we also have someoene in Canada starting, so we’re looking forward to broadening the types of stories we tell.

first_imgBy Kyra E. Azore, Originally published by The Grio (www.thegrio.com)For more than 150 years, Howard University has been located on sacred land. This great institution has been the training ground for so many global change agents such as activist Kwame Ture, writer Zora Neale Hurston, Supreme Court Justice Thurgood Marshall, Congressman Elijah Cummings, and Tony award winning actress, Phylicia Rashad. Yet, despite its historical significance, our beloved HU is being treated like a common public park.In the last few weeks, as spring has sprung and the first buds are making themselves known, the campus has received an influx of visitors. Some of them travel in large groups and stop students on their way to class to ask for help with trivia questions from the Admission Center’s scavenger hunt.Kyra E. Azore (LinkedIn Photo)Clearly, these are prospective students and their parents who likely already understand what Howard means to the Black community. Others trek across “the Yard,” the open clearing carved by pathways that connect the main buildings on campus, with their picnic baskets, small children, yoga mats, pure-bred dogs and a palpable sense of entitlement.We are talking about a place that is deeply connected to every major event in the Howard community since its founding—from traveling students sleeping on the floor of Founders Library the night before the Million Man March to Muhammad Ali sitting on the steps of Douglass Hall surrounded by students giving a speech about denying the draft. The hallowed paths of Howard have seen more celebrities and thought leaders than any red carpet in the world.Howard University is my home and has been ever since I first visited the campus in 2013, I remember that day like it was yesterday. I was a sophomore in high school visiting colleges during my spring break. Unlike all the other places I visited, this felt most like home. When I finally climbed the hill to the Yard, I marveled in the sight of young, Black students in suits and the latest fashions, treating the pathways like their own personal runway.The Yard is the heartbeat of the University. It’s the host to Yardfest during Howard’s infamous homecoming and the backdrop for the annual commencement activities. To see it now littered with jogging pedestrians and nonchalant dog walkers infuriates me. I am also aware that these are the same people who have driven up the surrounding property value to the point where most students who live off campus have no choice, like myself, but to find apartments in neighboring states because we cannot afford to live adjacent to where we take classes.The frustration that students experience is rooted in the fact that these are the same people who call the police to complain about our house parties and campus events, but then go ahead and picnic under the trees that are dedicated to our historic Greek letter organizations.Excuse me? There’s a free, public park across the street where you can knock yourself out with all your healthy-living activities.Black students see Howard as a safe space, where we can seek refuge from trials of the outside world of our campus. These interlopers, on the other hand, seem to be treating Howard’s campus like a community park, where those new to the area have felt free to lounge, enjoy a Spring day, and “deal” with the inconveniences that come with the patch of land that also happens to double as an institution of higher learning when they are not using it.Since its founding in 1867, Howard has been an open campus regularly engaging students and neighbors from the surrounding communities, who at the time, looked like us. This wasn’t always an easy situation as I think back to what it must have been like to be a student here when the streets of Chocolate City surrounding the University were drug and crime infested 1980s and 1990s. And yet, Howard never closed its gates and turned its back on the community. In doing so, unfortunately, it seems our latest visitors have taken the kindness of an open campus as a weakness.Let me be the first to tell them this is not the case.Please do not be confused or misled. This has been an ongoing issue at Howard over the past few years. In 2015, the hashtag #WeAreNotAPark surfaced on social media because students were outraged when this first started happening to our space. Concerned students reached out to student government to act on their behalf, but not much else was done afterwards. I believe this #WeAreNotAPark movement didn’t receive much traction because some students felt like the hashtag was divisive and would only cause conflict in the community.This most recent clash has emerged on social media as #HowardWontMove. This time is going to be different because the current student body is less in favor of respectability politics. We are talking about the same students who took over the Administration building last year bumping “Knuck If You Buck” and demanding the removal of chief university administrators in the wake of a misappropriation of financial aid funds scandal.To be clear, this issue is not solely about race because it’s also about respect. Respect the sacred ground that is Howard University. You do not get to complain about our unique HBCU experiences (Homecoming, etc.) and then use our campus for your leisure activities. That is not how this works.Don’t like the noise from our parties on Saturday night? Then you’re probably not going to like the shade from our trees on the Yard on Tuesday afternoons. The idea that the interlopers are able to pick and choose which parts of Howard they are willing to accept or allow to be acceptable is at the heart of the issue. Like the rest of the Black experience, you have to take us or leave us as is. Howard is not a restaurant that allows for substitutions or additions so you can have it your way.The amount of entitlement displayed by community members like Sean Grubbs-Robishaw, who has since been dubbed #GentrifyingGeorge by Black Twiiter and lives in the Shaw-Howard neighborhood where Howard resides. In a television interview with the local Fox affiliate, Grubbs-Robishaw famously suggested all of Howard “just move the campus” if we do not want people walking their dogs across the Yard.Rather than educate themselves about these historic grounds, they disgrace us and our home. The blatant disrespect, unmitigated gall is baffling.How dare you?It begs repeating, for more than 150 years, Howard has sat proudly on Hilltop high overlooking most of D.C., but now that we are in the way of community expansion, we’re expected to just move? That is not how this works. Just like we respect your wishes about parties and noise you should be able to honor a simple request not to treat my expensive educational home as your cheap dog park. I should be able to strut across the Yard to class with my head held high, not constantly scanning the ground to avoid poop from your privileged pooch.Just for the record, when you choose to live next to a college campus, you sign up for all that comes with it, so take it or leave it. Regardless of what you decide, Howard will remain unphased, a prideful symbol of tradition, and unmoved.Just try to move us and see what happens.#HUStrongThe opinions on this page are those of the writers and not necessarily those of the AFRO.Send letters to The Afro-American • 1531 S.

first_img Citation: Researchers design plasmonic cavity-free nanolaser (2014, September 22) retrieved 18 August 2019 from https://phys.org/news/2014-09-plasmonic-cavity-free-nanolaser.html (Phys.org) —A team of researchers at Imperial College in London has designed a new type of laser, one that could be made much smaller than today’s models because it would be cavity-free. In their paper published in the journal Nature Communications, the team describes their idea and offer possible uses for such a laser should they be able to build one.

While this method has worked extraordinarily well for a host of applications, there is still one area where it is lacking—applications at the nanoscale. This is because, the researchers note, the need for the cavity. In this new effort, the researchers have created a design for a very tiny laser that works without a cavity and is able to do so by taking advantage of prior research into stopping light.The envisioned laser (the team hasn’t actually built one yet) would be made by pressing two metals together, with an insulating material between them, resulting in a sandwich of sorts. Pulses of light sent through the middle part of the sandwich would reverse direction upon encountering the metal part, causing the light to become trapped in a vortex, which means it would be stopped. The researchers have found that in testing their idea, light sent into the laser would get trapped in the vortex for approximately 10 trillionths of a second before breaking free in the form of a beam of light. In addition to being cavity-free, the laser would also be able to emit laser beams with a range of frequencies.With the design created and tested, the team is now moving towards building a prototype of the new type of laser—they believe it could be used in optics applications, perhaps as part of a computer. Others have suggested that if such a laser could be built, it could be used in such diverse applications as signaling, or even prosthetics, because it could be embedded in synthetic tissue.center_img More information: Cavity-free plasmonic nanolasing enabled by dispersionless stopped light , Nature Communications 5, Article number: 4972 DOI: 10.1038/ncomms5972AbstractWhen light is brought to a standstill, its interaction with gain media increases dramatically due to a singularity in the density of optical states. Concurrently, stopped light engenders an inherent and cavity-free feedback mechanism, similar in effect to the feedback that has been demonstrated and exploited in large-scale disordered media and random lasers. Here we study the spatial, temporal and spectral signatures of lasing in planar gain-enhanced nanoplasmonic structures at near-infrared frequencies and show that the stopped-light feedback mechanism allows for nanolasing without a cavity. We reveal that in the absence of cavity-induced feedback, the subwavelength lasing mode forms dynamically as a phase-locked superposition of quasi dispersion-free waveguide modes. This mechanism proves remarkably robust against interface roughness and offers a new route towards nanolasing, the experimental realization of ultra-thin surface emitting lasers, and cavity-free active quantum plasmonics. Explore further An off-center waveguide enables light to be efficiently extracted from nanoscale lasers (a) The core layer of the metal-dielectric (SL) multilayer structure is filled with gain material (blue). (b) Spatially selective excitation of the homogeneous gain layer using a near-field tip leads to the formation of a subwavelength spot of inverted gain, in which the stimulated emission processes take place (inset). Photons are trapped locally in a closed-loop energy vortex (red curved arrows), enabled by an SL point, SL1, at (ω1, k1) that aligns with the peak gain. (c) A second SL point, SL2, at (ω2, k2) enforces a monotonous behaviour of the dispersion over a range of wavevectors with an average slope of (ω2−ω1)/(k2−k1). Bringing the frequencies of the SL points close together while maintaining a large distance in k-space flattens the dispersion to within the bandwidth of the gain (blue), allowing for the formation of highly localized, SL wave packets during lasing operation.

first_imgComparison of measured and time-integrated Th/U in zircon. The panel a is for oldest known terrestrial igneous zircons, whereas panel b is for oldest known terrestrial detrital zircons from Western Australia. Time-integrated means calculated from measured 208Pb/206Pb ratio and 207Pb/206Pb age. Corresponding data can be found in Credit: Nature Communications, doi: 10.1038/s41467-019-10382-y LEFT: Influence of Pb mobility on present-day 207Pb/206Pb ages and time-integrated Th/U. The panel (a) shows the effect of Pb-loss and Pb-addition on determined 207Pb/206Pb ages for a 4430 Ma zircon with original Th/U of 1, whereas the panel (b) presents the effect of Pb-loss and Pb-addition on time-integrated Th/U for the same zircon. Percentages next to the dotted-curves correspond to the degree of Pb-loss or Pb-addition. The age of perturbation refers to the age at which the Pb is lost or added. Note that Pb-addition corresponds to local increase in radiogenic Pb concentration and not addition of common Pb. This figure illustrates the great sensitivity of 207Pb/206Pb ages to Pb mobility whereas it has a limited effect on time-integrated Th/U. RIGHT: Time-integrated Th/U as a function of that measured for Martian zircons. Data are from previous studies. Note the large decoupling between measured and time-integrated Th/U for domains within zircon Z2 from NWA 7533. Measured Th/U are also well outside the common magmatic range, much as what can be seen in Jack Hills zircons. Error bars represent two standard errors on analytical measurements. Corresponding data can be found in Credit: Nature Communications, doi: 10.1038/s41467-019-10382-y Via extensive experiments, Guitreau and Flahaut showed that decoupling between the measured and time-integrated Th/U exhibited by terrestrial zircons as a proxy for zircon alterations by aqueous solutions at low temperatures. Upon comparison, the scientists showed that lunar (moon) zircons exhibited anomalously high Th/U in compliance with the common range for terrestrial larva/magma based igneous (fiery) zircon. This was expected since there is no evidence for liquid water on the moon. Similarly, Martian zircon crystals obtained from the meteorite NWA 7533 and the matrix of NWA 7034 showed consistent measurements and time-integrated Th/U ratios. Based on existing data and the present calculations, Guitreau and Flahaut interpreted the horizontal distribution as evidence for low temperature alterations of Martian zircon grains by aqueous solutions—much like the crystals from Western Australia. The present findings using decoupling between the measured and time-integrated Th/U ratios reinforced the idea of the availability of liquid water in the Martian subsurface. The phenomenon induced advanced weathering of radiation-damaged zircon crystals. Explore further In the present work, Guitreau and Flahaut explored if decoupling between the measured and time-integrated Th/U in Zircon could proxy for low-temperature aqueous alterations and then outlined the principles of their new method. When the scientists applied the method to extraterrestrial zircons on the moon for comparison with Martian zircons, they obtained evidence for low-temperature aqueous weathering on Mars. In this way, Guitreau and Flahaut presented their new data with robust evidence from existing investigations to indicate that the low-temperature alteration event recorded in NWA zircons occurred in the late Amazonian period on Mars. They assume that the availability of water for weathering in the late-Amazonian was likely controlled by impact-induced hydrothermal activity. The observations in the present study were consistent with post-brecciation (rock fragmentation) zircon alteration, and the youngest volcanic activity on Mars could also have played a role due to alterations with the current cryosphere. The recorded alterations of Zircons in the NWA 7533 meteorite represented the youngest episode of persistent aqueous alteration thus far reported on Mars. The results support the concept that Mars may yet be habitable relative to the evidenced availability of liquid water in its recent past. Calculated radiation doses as a function of Th/U in zircon. The panels a, b and c correspond to data from previous studies. Note the general upward-opening fan shape distribution of data above the first percolation point (stage at which amorphous domains become connected). Corresponding data can be found in Credit: Nature Communications, doi: 10.1038/s41467-019-10382-y Many accounts at present support the presence of liquid water on Mars, where hydrated minerals testify to past processes of aqueous weathering in Martian meteorites such as NWA 7533/7034. Planetary scientists aim to estimate the timing of weathering on the Martian crust to help understand its evolution, the availability of liquid water and habitability on Mars. In a recent study, Martin Guitreau and Jessica Flahaut at the University of Manchester, U.K., and the National Center for Scientific Research in France, presented a new method based on U-Th-Pb (Uranium-Thorium-Lead) isotope dating systems. Using the technique, Guitreau and Flahaut investigated if Zircon crystals underwent low-temperature aqueous alteration, similar to observations with Hadean-aged detrital crystals from Western Australia. Results for the two-stage model simulating Martian zircon evolution. Models were run for U enrichment factors of 5 for panels (a) and (b), whereas a factor of 2 was used for the results presented in panels (c) and (d). The pre-alteration Th/U was set to 1 for models shown in panels a and c, and it was set to 0.5 in panels (b) and (d). Th/U ratios increased by alteration were set to 1–27 and 0.5–27, depending on the pre-alteration Th/U. Colored curves correspond to measured Th/U in zircon Z2 domains. The U–Pb resetting age corresponds to the lower intercept of the general Discordia line displayed in a previous study and is represented by a solid vertical line. The horizontal dashed lines, which are the intercepts between the colored curves and the solid vertical line, indicate the time-integrated Th/U deduced from our model. The gray-shaded zones between Th/U values of 1 and 2 correspond to the time-integrated Th/U exhibited by zircon Z2 domains. These results show that time-integrated Th/U derived from the current model are higher than those exhibited by zircon Z2 domains, and, hence, alteration at 1700 Ma (or 1500 Ma) cannot account for the observed decoupling between measured and time-integrated Th/U in the study.

The finding largely expands the time duration in which liquid water was available near the Martian surface—suggesting that Mars may still be habitable, based on the evidence. Results of the study are now published on Nature Communications. Zircon is a robust time capsule extensively used in U-Pb geochronology and in the study of magmatic/metamorphic processes on Earth. Planetary scientists have testified this process using terrestrial detrital Zircon predating to 4378 million years. Nevertheless, the alpha-particle emission and α-recoil cascades due to U and Th decay can damage the crystal lattice, causing radiation to accumulate in zirconium at different rates based on the concentrations (ratio) of U and Th. This stage is defined as the “first percolation point” after which chemical elements can be more readily mobilized than in pristine crystals. The progressive amorphization can induce crystal lattice expansion and crack formation in Zircon to enhance the crystal’s sensitivity to thermal events as observed with ancient Zircons from Jack Hills, Western Australia. When they modeled the evolution of the U-Th-Pb isotope systems of zircon to determine the development of decoupling between the measured and time-integrated Th/U, they discovered the alteration occurred at 1500-1700 Ma; as a much younger event. The event corresponded to the late Amazonian period, which is generally considered cold and dry on Mars. As a result, the present work demonstrated the availability of water near the Martian surface in the recent past, suggesting its presence in the present day. To investigate the sensitivity of Zircon, the scientists considered chemical modifications as well as isotopic resetting during preservation of the lattice. To assess these conditions, they used macroscopic visual criteria and microscopic methods including transmission electron microscopy, Raman spectroscopy, X-ray diffraction, nuclear magnetic resonance and atom probe tomography. A simpler, indirect approach is to also calculate the radiation dose that a zircon sample underwent (alpha decay events per gram of sample) using chronological information provided by U-Pb isotype systems and U and Th concentrations. For example, when scientists calculated the radiation doses of Jack Hills zircon datasets, they showed decoupling between the measured and time-integrated Th/U ratios in zircon domains. In this instance, radiation doses appeared to accumulate beyond the first percolation point, however the process required verification prior to its use on aqueous alterations beyond Earth. To understand the timing of Marian aqueous weathering, Guitreau and Flahaut developed a two-stage model of the U-Th-Pb isotope evolution in the present work. They tested if an aberration event (deviation) at 1500 or 1700 Ma could have accounted for the observed decoupling between the measured and time-controlled Th/U and the zircon alteration in NWA 7533. In the first stage of the model, Guitreau and Flahaut investigated zircon formation at 4430 Ma, followed by the second stage as an alteration event on increasing U and Th concentrations to alter zircon in the NWA 7533 meteorite. Using the two-stage model, they showed that uranium could be enriched by 2-5 times the original concentration to match both Jack Hills and Martian Zircon data. The results indicated that the observed levels of Th/U could have occurred at 1700 Ma or 1500 Ma. The scientists further implemented the model with an additional stage to form a three-stage model, using the same Th/U ratios and Uranium enrichment factors as in the two-stage model. The results showed that while the determined alteration ages remained very young, the specific alterations recorded by the scientists occurred during the late Amazonian period.
