Race to save Chilean miners trapped underground from spiralling into depression continues

Thursday, September 2, 2010

It has emerged that the 33 Chilean miners trapped underground after the mine they were working in collapsed could be brought to the surface in a shorter time than was initially feared. While officials publicly announced that the men would not be brought to the surface until Christmas, sources inside technical meetings have revealed that they could in fact be on the surface by early November. The news comes as families were allowed to speak by radio-telephone to their trapped loved ones on Sunday. Over the weekend, video images filmed by the miners emerged showing the miners playing dominoes at a table and singing the Chilean national anthem. The miners also used the camera to send video messages to their families on the surface, saying that they regularly broke into tears, but were feeling better having received food and water.

The grainy nightvision images, filmed on a high definition camcorder that was sent down a small shaft to the mine, show the men in good spirits, chanting “long live Chile, and long live the miners.” They are unshaven and stripped to the waist because of the heat underground, and are seen wearing white clinical trousers that have been designed to keep them dry. Giving a guided tour of the area they are occupying, Mario Sepúlveda, one of the miners, explains they have a “little cup to brush our teeth”, and a place where they pray each day. “We have everything organized,” he tells the camera. Gesturing to the table in the center of the room, he says that “we meet here every day. We plan, we have assemblies here every day so that all the decisions we make are based on the thoughts of all 33.” Another unidentified miner asks to rescuers, “get us out of here soon, please.” A thermometer is shown in the video, reading 29.5C (85F).

As the film continues, it becomes evident that the miners have stuck a poster of a topless woman on the wall. The miners appear shy, and one man puts his hand to his face, presumably dazzled by the light mounted on the cameraman’s helmet. One miner sent a message to his family. “Be calm”, he says. “We’re going to get out of here. And we thank you from the bottom of our hearts for your efforts.” Another said that the miners are “sure that there are people here in Chile that are big people, that are powerful people, that are intelligent people, and they have the technology and they will all work together to get us out of here.” Speaking to the camera, one says: “we have had the great fortune that trapped in this mine there are good, professional people. We have electricians, we have mechanics, we have machine operators and we will let you know that while you are working to rescue us on the surface, we are down here ready to help you too.” It has been reported that Mario Gómez, 63, has become the group’s “spiritual leader”, having worked in the mines for over fifty years. He has requested that materials to build a shrine be sent down to the cavern.

Upon seeing the video in a private screening, family members, who are living in a small village of tents at the entrance to the San José copper-gold mine—which they have named Camp Hope—were elated. “He’s skinny, bearded and it was painful to see him with his head hanging down, but I am so happy to see him alive”, said Ruth Contreras, the mother of Carlos Bravo, who is trapped in the mine. The video, of which only a small portion has been released to the public, shows the miners, many of them wearing helmets, cracking jokes and thanking the rescuers for their continued efforts. The supplies are being sent to the men through a small shaft only twelve centimeters wide, and a laboratory has been set up with the purpose of designing collapsible cots and miniature sandwiches, which can be sent down such a narrow space.

CNN reported on Friday that “officials are splitting the men into two shifts so one group sleeps while the other works or has leisure time .. On average, each man has lost 22 pounds (10 kilograms) since they became trapped three weeks ago, and dehydration remains a threat. But a survey of the men indicates that at least nine miners are still too overweight to fit through the proposed rescue shaft. Initially, the miners survived by draining water from a water-cooled piece of equipment. To stay hydrated in the 90-degree mine, each miner must drink eight or nine pints of water per day.”

But while there are jubilant celebrations on the surface that the miners are alive, officials are now nervous that the miners could become depressed, trapped in a dark room the size of a small apartment. Chilean health minister Jaime Mañalich said that, on the video, he saw the telltale signs of depression. “They are more isolated, they don’t want to be on the screen, they are not eating well”, he said. “I would say depression is the correct word.” He said that doctors who had watched the video had observed the men suffering from “severe dermatological problems.” Dr. Rodrigo Figueroa, head of the trauma, stress and disaster unit at the Catholic University in Santiago, Chile, explained that “following the euphoria of being discovered, the normal psychological reaction would be for the men to collapse in a combination of fatigue and stress … People who are trained for emergencies – like these miners – tend to minimize their own needs or to ignore them. When it is time to ask for help, they don’t.” NASA has advised emergency workers that entertaining the miners would be a good idea. They are to be sent a television system complete with taped football matches. Another dilemma facing Mañalich is whether the miners should be permitted to smoke underground. While nicotine gum has been delivered to the miners, sending down cigarettes is a plan that has not been ruled out.

With the news that drilling of the main rescue tunnel was expected to begin on Monday, officials have informed the media that they hope to have the miners out of the mine by Christmas—but sources with access to technical meetings have suggested that the miners could actually be rescued by the first week of November. A news report described the rescue plan—”the main focus is a machine that bores straight down to 688m and creates a chimney-type duct that could be used to haul the miners out one by one in a rescue basket. A second drilling operation will attempt to intercept a mining tunnel at a depth of roughly 350m. The miners would then have to make their way through several miles of dark, muddy tunnels and meet the rescue drill at roughly the halfway point of their current depth of 688m.” Iván Viveros Aranas, a Chilean policeman working at Camp Hope, told reporters that Chile “has shown a unity regardless of religion or social class. You see people arriving here just to volunteer, they have no relation at all to these families.”

But over the weekend, The New York Times reported that the “miners who have astonished the world with their discipline a half-mile underground will have to aid their own escape — clearing 3,000 to 4,000 tons of rock that will fall as the rescue hole is drilled, the engineer in charge of drilling said Sunday … The work will require about a half-dozen men working in shifts 24 hours a day.” Andrés Sougarret, a senior engineer involved in operating the drill said that “the miners are going to have to take out all that material as it falls.”

The families of those trapped were allowed to speak to them by radio-telephone on Sunday—a possibility that brought reassurance both the miners and those on the surface. The Intendant of the Atacama Region, Ximena Matas, said that there had been “moments of great emotion.” She continued to say that the families “listened with great interest and they both felt and realized that the men are well. This has been a very important moment, which no doubt strengthens their [the miners’] morale.” The phone line is thought to be quite temperamental, but it is hoped that soon, those in the mine and those in Camp Hope will be able to talk every day. “To hear his voice was a balm to my heart … He is aware that the rescue is not going to happen today, that it will take some time. He asked us to stay calm as everything is going to be OK … He sounded relaxed and since it was so short I didn’t manage to ask anything. Twenty seconds was nothing”, said said Jessica Cortés, who spoke to her husband Víctor Zamora, who was not even a miner, but a vehicle mechanic. “He went in that day because a vehicle had broken down inside the mine … At first they told us he had been crushed [to death].”

Esteban Rojas sent up a letter from inside the mine, proposing to his long-time partner Jessica Yáñez, 43. While they have officially been married for 25 years, their wedding was a civil service—but Rojas has now promised to have a church ceremony which is customary in Chile. “Please keep praying that we get out of this alive. And when I do get out, we will buy a dress and get married,” the letter read. Yáñez told a newspaper that she thought he was never going to ask her. “We have talked about it before, but he never asked me … He knows that however long it takes, I’ll wait for him, because with him I’ve been through good and bad.”

Spelbound declared winner of Britain’s Got Talent 2010

Monday, June 7, 2010

An acrobatic group known by the name of Spelbound has been declared as the winner of Britain’s Got Talent 2010, a televised variety talent show competition broadcast on ITV in the United Kingdom. As the winning act of the show, Spelbound have won £100,000 (US$144,580, 120,313, A$175,079) and a place at The Royal Variety Performance, an annual gala evening that is attended by senior members of the British Royal Family.

In no particular order, the top three acts were revealed to be two dancers known by their stage name of Twist and Pulse, gymnastic group Spelbound and Kieran Gaffney, whose act involves playing on the drum kit. After Kieran Gaffney was revealed to be in third place, Anthony McPartlin, who hosts Britain’s Got Talent with Declan Donnelly, said to Kieran: “Well done Kieran. Kieran, you’re a star, you came back, you got all the way to the final. I know you’ve loved this. You’ve loved this, haven’t you?” In response to this, Kieran Gaffney stated: “Thank you very much. Thank you, everyone for supporting me. Thank you.”

Shortly afterwards, on the episode that was broadcast live on ITV1 on Saturday, Anthony announced: “After tens of thousands of auditons, five semi-finals and an amazing final, this…this is it. One of you is about to walk away with £100,000 and a place at this year’s Royal Variety Performance. The winner of Britain’s Got Talent 2010 is…Spelbound!” Glen Murphy from Twist and Pulse commented about finishing in second place, stating: “Yeah, it’s amazing. I can’t even believe it. I can’t believe it at all.”

Alex Uttley, a 24-year-old member of Spelbound, commented on the gymnastic group’s victory, commenting: “Oh, my god. This is unbelieveable. We just want to say thank you to everyone out there. It just shows that all our hard work has paid off.” One of the coaches of Spelbound, named Neil Griffiths, stated about Spelbound: “Oh, they’ve worked so hard over the last few weeks. Um, since the semi-final, we…we really had to pull out the stops to try and up the game. They’ve not known they’ve worked in the gym from six in the morning till twelve…twelve o’clock of the night. I couldn’t have asked for more. Um, it’s a team of coaches. I don’t take all the credit myself. There’s, uh, two people up there that know who they are who’ve been fantastic.”

Spelbound consists of 24-year-old Alex Uttley, Nicholas Illingworth, aged 24, Adam Buckingham, aged 21, 20-year-old Adam McAssey, 19-year-old Douglas Fordyce, 18-year-old Edward Upcott, 18-year-old Leighanne Cowler, 17-year-old Katie Axten, 17-year-old Lauren Kemp, 15-year-old Jonathan Stranks, Abigail Ralph, aged 15, 13-year-old Hollianne Wood and Amy Mackenzie, aged 12. Bookmakers had previously predicted that Spelbound would be the most likely act to become the winner of the series.

The running order for the final started with Twist and Pulse. The second act to perform was Liam McNally, a 14-year-old singer. The running order subsequently continued with 40-year-old impressionist Paul Burling, singer Christopher Stone, aged 28, Tina & Chandi, a woman and dog dancing act, Connected, a five-piece singing group, Kieran Gaffney, aged 12, 22-year-old Tobias Mead, a dancer, 80-year-old singer Janey Cutler and Spelbound in that particular order.

Earlier on in the final, Britain’s Got Talent judge Amanda Holden has stated to Spelbound: “We are hosting the 2012 Olympics and I think ‘what a brilliant opening act’.” Fellow judge Piers Morgan also commented that “[t]he purpose of this show is to identify hidden great British talent. You are that act.” After Spelbound won in the final, another judge, named Simon Cowell, stated that “the right boys and girls won on the night” and that he could “only say on live TV that that was one of the most astonishing things I have ever seen. Seriously.”

Popular soap opera ‘The Young and the Restless’ celebrates 35 years on the air

Wednesday, March 26, 2008

The popular American soap opera The Young and the Restless, currently the reigning Emmy Award-winner for best daytime drama, celebrated 35 years on the air Wednesday.

The 35th anniversary also comes after the series, known colloquially as Y&R, marked its 1,000th straight week as the highest-rated soap opera in a daytime slot. In addition to keeping the #1 spot every week since December 1988, Y&R has also been the top-rated soap in the African-American demographic since 1991.

A trend-setter since the beginning, Y&R relied on character-driven storytelling, accentuated with understated sexuality from its cast, which at that time was mostly young, in order to bring in teenage and twentysomething viewers who were ignored by soap producers and networks up to that time. These traits immediately set Y&R apart from other soap operas, and other soaps have since mimicked Y&R’s formulaic approach to offering something for everyone, especially younger viewers.

Since premiering on March 26, 1973, Y&R has become a worldwide cultural institution in its own right, racking up an impressive 100 Emmy Awards between the writers, producers, cast and crew since 1974. The show has aired in over 100 countries, including Australia, New Zealand, France, Germany, Italy, and Turkey, and reaches a worldwide audience of ten million daily. So far-reaching was Y&R’s appeal that Romanian gymnast Nadia Comaneci chose the serial’s theme song as accompanying music to her floor exercises at the 1976 Summer Olympics. In Australia, where Y&R has aired since 1974, the show was canceled by the original network that aired it in 2007, prompting a widespread fan backlash in that country. It was quickly moved to a pay channel.

Over the past 35 years, countless characters, marriages, divorces, births, deaths, and every joy and trauma in between have visited the residents of Genoa City, where Y&R is set. To commemorate the milestone, Mike Halterman from Wikinews interviewed three actresses who have played long-running characters on Y&R, and asked them to share their memories. All three responded to questions about what being on Y&R means to them, what their favorite storylines were, what they perhaps would have wanted to do all over again, and what they’d love to tell their fans directly.

Below are portions of all three interviews.

New Zealand dollar hits new high versus the United States dollar

Tuesday, July 17, 2007

File:New Zealand money.jpg

The New Zealand dollar (NZD) value rose and, for a short amount of time, was worth US$0.7932, the highest level in New Zealand since the dollar was floated in 1985 — 22 years ago.

The value then dropped a little and as of 11.40 a.m. was trading at US$0.7925. This was due to the Reserve Bank of New Zealand announcing that it will intervene next week at their Official Cash Rate review if the dollar continued to rise.

Economists are predicting that the NZD will now go above US$0.80.

The cause of this rise was mainly due to the release of the June quarter retail sales data. The consumer price index data showed that sales increased by 1.2%, instead of the predicted 0.4%. The bigger than expected sales data were mainly due to supermarket, car and petrol purchases. In May, the core sales figures showed a 0.8% rise, these figures excluded car and fuel sales.

Economist correspondents for Radio New Zealand have also said that a weak US dollar is also to blame for the rising New Zealand dollar. Danika Hampton, currency analyst for the Bank of New Zealand, says the NZD is looking expensive and doubts if it will maintain its current high figure.

Michael Cullen, the finance minister of New Zealand, has said that investors will be hurt when the New Zealand dollar does fall. Dr Cullen personally believes that the NZD is currently overvalued.

The Wellington Chamber of Commerce has called for the New Zealand Government to slow down it’s spending. Charles Finny, from the Chamber of Commerce, says this is one of the core factors, more than the oil and housing markets, despite speculation. Worldwide oil prices are at a current 11-month high.

The retails sales figures also resulted in Government bonds being weakened. The two-year and ten-year Government bonds are at 7.61% and 6.82% respectively.

The Official Cash Rate is currently at 8%, due to other interventions by the Reserve Bank.

The NZD is also trading well against the Australian dollar and Japanese yen.

Robin OBrien

In days gone by, yarn was obtained locally. It was usually hand-dyed, of high quality and unique. Things changed, and knitters bought branded yarns that were chemically dyed, of regular though unremarkable quality and were the same the world over. Thank heavens things are changing, and fast! Today, we are seeing the resurgence of unique and beautiful yarns. What follows is a tiny selection of what’s now available.

No matter how long you’ve been knitting for there is always something new to learn or yarns that you haven’t yet tried. If you’re looking for a yarn that’s different you’re spoilt for choice. And, you don’t have to go to craft fairs, knitting workshops or join specialist knitting groups to get hold of these beautiful, traditionally made yarns. Many yarn suppliers and yarn stored now stock these unusual yarns and, thanks to the Internet, you can even buy these yarns online.

UK company “seriously considering” GPS tracking devices in school uniforms

Saturday, August 25, 2007

The leading supplier of school uniforms in the United Kingdom, Lancashire-based manufacturer Trutex, has announced it is “seriously considering” including GPS tracking devices in future ranges of its uniform products after conducting an online survey of both parents and children.

“As a direct result of the survey, we are now seriously considering incorporating a [tracking] device into future ranges” said Trutex marketing director Clare Rix.

The survey questioned 809 parents and 444 children aged nine to 16. It showed that 44% of parents were worried about the safety of pre-teen children, and 59% wanted tracking devices installed in school apparel. 39% of children aged nine to 12 were prepared to wear clothing with tracking devices in them, while teenagers were notably less enthusiastic and more wary of what Trutex has admitted they see as a “big brother” concept.

However, Trutex has claimed the tracking devices would bring about worthwhile benefits, including being a valuable resource for parents who wanted to keep a close eye on where their children were at all times.

“As well as being a safety net for parents, there could be real benefits for schools who could keep a closer track on the whereabouts of their pupils, potentially reducing truancy levels” says Rix.

Each year, Trutex supplies 1 million blouses, 1.1 million shirts, 250,000 pairs of trousers, 20,000 blazers, 60,000 skirts and 110,000 pieces of knitwear to the UK.

It is not the first company to manufacture school uniforms with a central focus on child safety; last week Essex firm BladeRunner revealed it was selling stab-proof school blazers to parents concerned about violence against their children. The blazers were outfitted with Kevlar, a synthetic fibre used in body armour. It has already received orders internationally, including Australia.

If the Trutex tracking devices go ahead, it is unclear where in the uniform they will be located.

Potential Wikia mass exodus

Friday, August 1, 2008

Recently Wikia, a commercial company co-founded by Jimmy Wales and Angela Beesley, announced that it would be making changes in the appearances of its wikis, specifically making advertising more prominent. This change to mix advertising directly into the content has led many Wikia hosted sites to begin discussions regarding leaving Wikia hosting for their own. As Wikia’s business model hinges entirely upon user-generated content, large numbers of sites leaving could leave Wikia in financial trouble. Wikia has lost editors and volunteer “janitors” as a result of this.

Some changes were made to make sure Wikia doesn’t lose its community; one of them being the ability for logged-in users to turn off advertisements in their personal preferences, which would eliminate the ads from all other pages except the main pages of different Wikia wikis. However, this didn’t help much and several wikis, most notably the Transformers Wiki advised their users to switch to Firefox browser and install the AdBlock plugin to remove advertisements. The problem was the excessive advertisements on every content pages which most of the Wikia communities didn’t agree with.

Since the new Monaco skin version 3.1. was rolled out across all Wikia-hosted wikis, Wikia introduced a set of “main page column tags” meant to aid in main page designing while minding Wikia’s new advertisements. Most, if not all Wikia’s English-language wikis, such as Wookieepedia, the Star Wars Wiki, Wiki 24 and WoWWiki have converted their main pages to use these new main page column tags. Wikia’s “helpers”, people working as interns for Wikia, have helped to convert wikis to the new main page layout. However, some wikis, such as the Transformers Wiki opposed the change to their main pages and thus refused to convert their main page to use the main page column tags. Newly-created Wikia wikis will have a main page that has the main page column tags by default.

Certain Wikia-hosted communities have criticized their host for trying to make Wikia look like one big website to please the advertisers when the communities would prefer to stay independent from other Wikia’s wikis.

During the rollout of the new Monaco skin, the phrase “Wikia will never host pop-up adverts.” was removed from Wikia’s terms of use and later reinstated into the terms. Several users thought that this might hint of upcoming pop-up ads at Wikia.

Researchers find preserving spotted owl habitat may not require a tradeoff with wildfire risk after all

Sunday, October 8, 2017

In a study scheduled for publication in the December 1 issue of Forest Ecology and Management, scientists from the University of California, Davis; USDA Forest Service Pacific Southwest Research Station; and University of Washington have found a way to resolve the conflict that has sprung up between protecting forests from increasingly frequent wildfires and droughts and preserving sufficient habitat for the endangered spotted owl, Strix occidentalis. The study was performed in two national parks in California, United States.

For the past twenty-five years, spotted owl habitat preservation has focused on keeping 70% or more of the total ground area covered by natural tree canopy, a tree density that leaves forests prone to wildfires and trees more likely to die during droughts. Both wildfires and droughts have become more frequent in the years since the program began.

However, the previous studies upon which the 70% figure was based only measured overall canopy coverage. In this work, researchers used aerial LiDAR (Light Detection And Ranging) imaging technology to scan areas within Kings Canyon National Park and Sequoia National Park in California. The regions were analyzed by distribution of foliage, tree height, and the sizes of the spaces between trees and stands. These data were then cross-referenced with decades of field studies showing the locations of hundreds of owl nests. They found that spotted owls clustered in areas with very tall trees and stands almost exclusively, over 150 feet (48 m), avoiding areas that only had moderate or low canopy, regardless of how dense or wide.

“This could fundamentally resolve the management problem because it would allow for reducing small tree density, through fire and thinning,” said lead author Malcolm North, of UC Davis and the USDA Pacific Southwest Research Station. “We’ve been losing the large trees, particularly in these extreme wildfire and high drought-mortality events. This is a way to protect more large tree habitat, which is what the owls want, in a way that makes the forest more resilient to these increasing stressors that are becoming more intense with climate change.”

The spotted owl gained national prominence in the United States during the 1990s, when environmentalists’ efforts to preserve its habitat resulted in federal measures forbidding logging on large swaths of land, as well as federal limits on the sales of harvested wood. There was a 1995 U.S. Supreme Court case which was preceded by lawsuits on the part of timber companies and by years of large protests by timber workers and their communities who feared job losses. For a time, it seemed that the spotted owl was also threatened by competition from the faster-breeding barred owl, which had moved west into its territory.

This is not the only major study of spotted owls to reach the public eye this week. On Thursday, the U.S. Fish and Wildlife Service released the California Spotted Owl Conservation Objectives Report, which analyzes the past several decades of research on the California spotted owl and provides recommendations for ecologically and economically viable conservation.
