U.S. restores full diplomatic relations with Libya

Tuesday, May 16, 2006

The U.S. has announced full diplomatic relations will be restored with Libya and the country removed from the list of nations the U.S. considers to be state sponsors of terrorism following a 45-day open comment period.

Renewal of diplomatic relations between the two states comes after extended diplomatic efforts by both parties to end the 25-year break.

“It is a result of mutual interests, agreements and understandings,” said Abdurrahman Shalgham, Libyan’s Foreign Minister.

“We are taking these actions in recognition of Libya’s continued commitment to its renunciation of terrorism and the excellent cooperation Libya has provided to the United States and other members of the international community in response to common global threats faced by the civilized world since September 11, 2001,” said Condoleezza Rice, the United States Secretary of State.

Diplomatic ties were strained between the countries following the rise to power of Libyan leader Muammar al-Gaddafi in 1969, and U.S. economic sanctions against the country beginning in the 1970s. They were severed following the U.S. removal of diplomatic personnel from Libya in 1979 after a mob set fire to the U.S. embassy in Tripoli, and the U.S. closing the Libyan embassy and expelling Libyan diplomats in 1981.

The UN removed international economic sanctions in 1999, following Libya’s acceptance of UN Security Council Resolutions regarding Pan Am Flight 103. In 2003 Libya announced efforts to dismantle military programs to develop weapons of mass destruction as well, which led directly to diplomatic negotiations with the U.S. and the opening of a diplomatic liaison office in Tripoli in 2004.

For Jamaica, 2012 Report on Gender Equality and Development focuses on men

Thursday, September 26, 2013

On Tuesday the World Bank released the 2012 World Development Report on Gender Equality and Development. For Jamaica the report highlights a number of negative gender issues for the nation’s men.

The report claims that getting an education in Jamaica is viewed as primarily a female activity. This cultural attitude encourages males to leave school early. In 2008, girls outnumbered boys in secondary school by a ratio of 1.04:1. At the same time, boys were more likely to have to repeat a year of school. Only 16% of boys passed five or more Caribbean Secondary Education Certificate exams compared to 30% of girls. Boys outperformed girls only in vocational subjects and physics. The report cites four key challenges in boys’ development identified by a national programme. They are low self-esteem, limited future employment opportunities, lack of discipline, and masculine identities that eschew education.

A program in Jamaica uses cash incentives to encourage at-risk boys to stay in school; other countries like Pakistan use cash incentives to encourage girls to stay in school. Jamaica’s program has resulted an average increase in boys attending school by 0.5 days a month. At the same time, fathers are urged to become more involved with their childrens’ schooling and changes are being made to the curriculum to make it “more boy-friendly”.

Definitions of masculinity result in less employment opportunities and smaller earnings potential. The report claims Jamaican definitions of masculinity also encourage more risky behavior, and sexual behaviors valuing achievement and competence above intimacy. The report says these factors increase physical and sexual violence towards women.

Male mortality is increasing in Jamaica. The report cites crime and violence as causes.

Eurovision ’73 winner Anne Marie David discusses her four-decade career and the Contest, past and present

Monday, February 16, 2009

In the 1970s, she was one of the most popular female vocalists in France, and became well-known internationally. Anne Marie David, from Arles in the south of France, parlayed her initial success from playing Mary Magdalene in the French production of Jesus Christ Superstar into taking home the “grand prix” at the Eurovision Song Contest in 1973. Her winning song, “Tu te reconnaîtras” (You will recognize yourself), became a Europe-wide hit that spring.

At the height of her popularity, David perfomed world tours, and even lived abroad in Turkey for a time. In 1979, she tried once again to win the Eurovision, and placed a respectable third. Her song “Je suis l’enfant soleil” (I’m a child of the sun) became similarly popular across France and in the Francophone nations.

As time went on, however, her place in the French music scene became less certain. Touring the world had taken a personal toll, and David decided to retire from music completely in 1987. However, with the help of her fan base, she was coaxed out of retirement in 2003 and is returning to a part of her life that she tried to leave, but never left her. Celebrating four decades in the music scene, David is looking forward to adventurous new projects and a newfound zest for life.

Anne Marie David corresponded with Wikinews’ Mike Halterman about her eventful career, her personal anecdotes regarding living abroad, her successes in past Eurovision contests and her grievances with the way the show is produced today. This is the second in a series of interviews with past Eurovision contestants, which will be published sporadically in the lead-up to mid-May’s next contest in Moscow.

US stock markets fall amid credit fears

Friday, August 3, 2007

The Dow Jones Industrial Average fell more than 280 points, Friday, to 13181.91, just two weeks after soaring to a historic record of 14,000. Two other major indexes, the Nasdaq and the Standard and Poor 500, fell more than 2% in a widespread market sell-off.

Shares of Bear Stearns, the largest United States underwriter of mortgage bonds, fell 6.3% today, resulting from Standard and Poor’s altering its outlook toward the company to “negative” from “stable”. The investment banking firm recently saw two of its major hedge funds sink after exposure to the sub-prime mortgage decline. Standard and Poor’s report said the firm may have problems, including its hedge funds, that could hurt the firm “for an extended period.”

The company held a press conference at noon, but was unable to salvage its stock, leading to heavy losses in the rest of the financial sector. Chief Financial Officer Sam Molinaro remarked that the credit market was in the worst condition he had seen in 22 years.

American Express shares fell 5.6%, while homebuilder Hovnanian Enterprises fell 9.4% in the sell-off which impacted all the indexes. American Home Mortgage Investment Corporation shares fell 52.07% in the session after announcing plans to close most operations and lay off over 6000 employees. The company has also lost its lending license in four states including New York.

“It is with great sadness that American Home has had to take this action,” Chief Executive Michael Strauss said in a statement. “Unfortunately, the market conditions in both the secondary mortgage market as well as the national real estate market have deteriorated to the point that we have no realistic alternative.”

Analysts say that the weakness in the stock markets and economy in general could prompt the Federal Reserve to lower interest rates, consequently allowing inflation to rise, but that it would also support stocks and ease borrowing. The Fed has not changed interest rates since June 2006.

Warhol’s photo legacy spread by university exhibits

Tuesday, January 28, 2014

Evansville, Indiana, United States — This past week marked the opening night of an Andy Warhol exhibit at the University of Southern Indiana. USI’s art gallery, like 189 other educational galleries and museums around the country, is a recipient of a major Warhol donor program, and this program is cultivating new interest in Warhol’s photographic legacy. Wikinews reporters attended the opening and spoke to donors, exhibit organizers and patrons.

The USI art gallery celebrated the Thursday opening with its display of Warhol’s Polaroids, gelatin silver prints and several colored screen prints. USI’s exhibit, which is located in Evansville, Indiana, is to run from January 23 through March 9.

The McCutchan Art Center/Pace Galleries at USI bases its exhibit around roughly 100 Polaroids selected from its collection. The Polaroids were all donated by the Andy Warhol Photographic Legacy Program, according to Kristen Wilkins, assistant professor of photography and curator of the exhibit. The Andy Warhol Foundation for the Visual Arts made two donations to USI Art Collections, in 2007 and a second recently.

Kathryn Waters, director of the gallery, expressed interest in further donations from the foundation in the future.

Since 2007 the Andy Warhol Photographic Legacy Program has seeded university art galleries throughout the United States with over 28,000 Andy Warhol photographs and other artifacts. The program takes a decentralized approach to Warhol’s photography collection and encourages university art galleries to regularly disseminate and educate audiences about Warhol’s artistic vision, especially in the area of photography.

Wilkins observed that the 2007 starting date of the donation program, which is part of the Andy Warhol Foundation for the Visual Arts, coincided with the 20th anniversary of Andy Warhol’s death in 1987. USI was not alone in receiving a donation.

K.C. Maurer, chief financial officer and treasurer at the Andy Warhol Foundation, said 500 institutions received the initial invitation and currently 190 universities have accepted one or more donations. Institutional recipients, said Mauer, are required to exhibit their donated Warhol photographs every ten years as one stipulation.

While USI is holding its exhibit, there are also Warhol Polaroid exhibits at the Tang Teaching Museum and Art Gallery at Skidmore College in Saratoga Springs, New York and an Edward Steichen and Andy Warhol exhibit at the Mary & Leigh Block Museum of Art at Northwestern University in Evanston, Illinois. All have received Polaroids from the foundation.

University exhibits can reach out and attract large audiences. For example, the Weatherspoon Art Museum at the University of North Carolina at Greensboro saw attendance levels reach 11,000 visitors when it exhibited its Warhol collection in 2010, according to curator Elaine Gustafon. That exhibit was part of a collaboration combining the collections from Duke University, located in Durham, North Carolina, and University of North Carolina at Chapel Hill, which also were recipients of donated items from the Andy Warhol Photographic Legacy Program.

Each collection donated by the Andy Warhol Photographic Legacy Program holds Polaroids of well-known celebrities. The successful UNC Greensboro exhibit included Polaroids of author Truman Capote and singer-songwriter Carly Simon.

“I think America’s obsession with celebrity culture is as strong today as it was when Warhol was living”, said Gustafon. “People are still intrigued by how stars live, dress and socialize, since it is so different from most people’s every day lives.”

Wilkins explained Warhol’s obsession with celebrities began when he first collected head shots as a kid and continued as a passion throughout his life. “He’s hanging out with the celebrities, and has kind of become the same sort of celebrity he was interested in documenting earlier in his career”, Wilkins said.

The exhibit at USI includes Polaroids of actor Dennis Hopper; musician Nick Rhodes of Duran Duran; publishers Jann Wenner of Rolling Stone Magazine and Carlo De Benedetti of Italy’s la Repubblica; disco club owner Steve Rubell of Studio 54; photographers Nat Finkelstein, Christopher Makos and Felice Quinto; and athletes Vitas Gerulaitis (tennis) and Jack Nicklaus (golf).

Wikinews observed the USI exhibit identifies and features Polaroids of fashion designer Halston, a former resident of Evansville.

University collections across the United States also include Polaroids of “unknowns” who have not yet had their fifteen minutes of fame. Cynthia Thompson, curator and director of exhibits at the University of Arkansas, Fayetteville, said, “These images serve as documentation of people in his every day life and art — one which many of us enjoy a glimpse into.”

Warhol was close to important touchstones of the 1960s, including art, music, consumer culture, fashion, and celebrity worship, which were all buzzwords and images Wikinews observed at USI’s opening exhibit.

He was also an influential figure in the pop art movement. “Pop art was about what popular American culture really thought was important”, Kathryn Waters said. “That’s why he did the Campbell Soup cans or the Marilyn pictures, these iconic products of American culture whether they be in film, video or actually products we consumed. So even back in the sixties, he was very aware of this part of our culture. Which as we all know in 2014, has only increased probably a thousand fold.”

“I think everybody knows Andy Warhol’s name, even non-art people, that’s a name they might know because he was such a personality”, Water said.

Hilary Braysmith, USI associate professor of art history, said, “I think his photography is equally influential as his graphic works, his more famous pictures of Marilyn. In terms of the evolution of photography and experimentation, like painting on them or the celebrity fascination, I think he was really ground-breaking in that regard.”

The Polaroid format is not what made Warhol famous, however, he is in the company of other well-known photographers who used the camera, such as Ansel Adams, Chuck Close, Walker Evans, Robert Mapplethorpe, and Helmut Newton.

Wilkins said, “[Warhol] liked the way photo booths and the Polaroid’s front flash looked”. She explained how Warhol’s adoption of the Polaroid camera revealed his process. According to Wilkins, Warhol was able to reproduce the Polaroid photograph and create an enlargement of it, which he then could use to commit the image to the silk screen medium by applying paint or manipulating them further. One of the silk screens exhibited at USI this time was the Annie Oakley screen print called “Cowboys and Indians” from 1987.

Wilkins also said Warhol was both an artist and a businessperson. “As a way to commercialize his work, he would make a blue Marilyn and a pink Marilyn and a yellow Marilyn, and then you could pick your favorite color and buy that. It was a very practical salesman approach to his work. He was very prolific but very business minded about that.”

“He wanted to be rich and famous and he made lots of choices to go that way”, Wilkins said.

It’s Warhol. He is a legend.

Kiara Perkins, a second year USI art major, admitted she was willing to skip class Thursday night to attend the opening exhibit but then circumstances allowed for her to attend the exhibit. Why did she so badly want to attend? “It’s Warhol. He is a legend.”

For Kevin Allton, a USI instructor in English, Warhol was also a legend. He said, “Andy Warhol was the center of the Zeitgeist for the 20th century and everything since. He is a post-modern diety.”

Allton said he had only seen the Silver Clouds installation before in film. The Silver Clouds installation were silver balloons blown up with helium, and those balloons filled one of the smaller rooms in the gallery. “I thought that in real life it was really kind of magical,” Allton said. “I smacked them around.”

Elements of the Zeitgeist were also playfully recreated on USI’s opening night. In her opening remarks for attendees, Waters pointed out those features to attendees, noting the touches of the Warhol Factory, or the studio where he worked, that were present around them. She pointed to the refreshment table with Campbell’s Soup served with “electric” Kool Aid and tables adorned with colorful gumball “pills”. The music in the background was from such bands as The Velvet Underground.

The big hit of the evening, Wikinews observed from the long line, was the Polaroid-room where attendees could wear a Warhol-like wig or don crazy glasses and have their own Polaroid taken. The Polaroids were ready in an instant and immediately displayed at the entry of the exhibit. Exhibit goers then became part of the very exhibit they had wanted to attend. In fact, many people Wikinews observed took out their mobiles as they left for the evening and used their own phone cameras to make one further record of the moment — a photo of a photo. Perhaps they had learned an important lesson from the Warhol exhibit that cultural events like these were ripe for use and reuse. We might even call these exit instant snap shots, the self selfie.

Italian football: Nainggolan moves to Inter Milan from Roma

Tuesday, June 26, 2018

Today, via their website, Milan-based Italian football club Internazionale announced the signing of Belgian midfielder Radja Nainggolan from AS Roma on a four-year contract which runs until June 30, 2022. The deal is worth an initial fee of €38 million, AS Roma announced via their official website.

30-year-old Nainggolan joined Roma in January 2014 and has featured in 203 goals for the club. During his tenure at the Italian-capital club, Nainggolan scored 33 goals. Last season, the Belgian scored six goals in all competitions as Roma finished third in the Italian Serie A league, and reached the semi-finals of the UEFA Champions League. Internationally, Nainggolan has played 30 matches for Belgium and scored six goals. Last month, Nainggolan retired from international football after he was left out of the Belgian team in this year’s FIFA World Cup in Russia.

After signing the contract, Nainggolan said, “Confidence is key and I received calls from Director [Piero] Ausilio, the Coach and [Javier] Zanetti. They all made me feel important and my decision was simple. I am ready to go ahead of this new adventure.” ((it))Italian language: ?L’importante è sentire la fiducia, mi hanno chiamato il Direttore Ausilio, il Mister e Zanetti. Mi hanno fatto sentire importante, la mia scelta è stata semplice. Sono carico per la nuova avventura.

With this move, Nainggolan will be reunited with former Roma coach Luciano Spalletti, who joined Inter a year ago. Inter’s Davide Santon and Nicolò Zaniolo made a move in the opposite direction, moving to Roma on a permanent basis.

As increase in digital music sales slows, record labels look to new ways to make money

Tuesday, August 31, 2010

Every September, the Apple iPod is redesigned. Last year saw the release of the iPod Nano 5th generation, bringing a video camera and a large range of colours to the Nano for the first time. But as Apple again prepares to unveil a redesigned product, the company has released their quarterly sales figures—and revealed that they have sold only 9m iPods for the quarter to June—the lowest number of sales since 2006, leading industry anylists to ponder whether the world’s most successful music device is in decline.

Such a drop in sales is not a problem for Apple, since the iPhone 4 and the iPad are selling in high numbers. But the number of people buying digital music players are concerning the music industry. Charles Arthur, technology editor of The Guardian, wrote that the decline in sales of MP3 players was a “problem” for record companies, saying that “digital music sales are only growing as fast as those of Apple’s devices – and as the stand-alone digital music player starts to die off, people may lose interest in buying songs from digital stores. The music industry had looked to the iPod to drive people to buy music in download form, whether from Apple’s iTunes music store, eMusic, Napster or from newer competitors such as Amazon.”

Mark Mulligan, a music and digital media analyst at Forrester Research, said in an interview that “at a time where we’re asking if digital is a replacement for the CD, as the CD was for vinyl, we should be starting to see a hockey-stick growth in download sales. Instead, we’re seeing a curve resembling that of a niche technology.” Alex Jacob, a spokesperson for the International Federation of the Phonographic Industry, which represents the worldwide music industry, agreed that there had been a fall in digital sales of music. “The digital download market is still growing,” they said. “But the percentage is less than a few years ago, though it’s now coming from a higher base.” Figures released earlier this year, Arthur wrote, “show that while CD sales fell by 12.7%, losing $1.6bn (£1bn)in value, digital downloads only grew by 9.2%, gaining less than $400m in value.”

Expectations that CDs would, in time, become extinct, replaced by digital downloads, have not come to light, Jacob confirmed. “Across the board, in terms of growth, digital isn’t making up for the fall in CD sales, though it is in certain countries, including the UK,” he said. Anylising the situation, Arthur suggested that “as iPod sales slow, digital music sales, which have been yoked to the device, are likely to slow too. The iPod has been the key driver: the IFPI’s figures show no appreciable digital download sales until 2004, the year Apple launched its iTunes music store internationally (it launched it in the US in April 2003). Since then, international digital music sales have climbed steadily, exactly in line with the total sales of iPods and iPhones.”

Nick Farrell, a TechEYE journalist, stated that the reason for the decline in music sales could be attributed to record companies’ continued reliance on Steve Jobs, CEO of Apple, saying that they had considered him the “industry’s saviour”, and by having this mindset had forgotten “that the iPod is only for those who want their music on the run. What they should have been doing is working out how to get high quality music onto other formats, perhaps even HiFi before the iPlod fad died out.”

When Jobs negotiated a deal with record labels to ensure every track was sold for 99 cents, they considered this unimportant—the iPod was not a major source of revenue for the company. However, near the end of 2004, there was a boom in sales of the iPod, and the iTunes store suddenly began raking in more and more money. The record companies were irritated, now wanting to charge different amounts for old and new songs, and popular and less popular songs. “But there was no alternative outlet with which to threaten Apple, which gained an effective monopoly over the digital music player market, achieving a share of more than 70%” wrote Arthur. Some did attempt to challenge the iTunes store, but still none have succeeded. “Apple is now the largest single retailer of music in the US by volume, with a 25% share.”

The iTunes store now sells television shows and films, and the company has recently launced iBooks, a new e-book store. The App Store is hugely successful, with Apple earning $410m in two years soley from Apps, sales of which they get 30%. In two years, 5bn apps have been downloaded—while in seven years, 10bn songs have been purchased. Mulligan thinks that there is a reason for this—the quality of apps simply does not match up to a piece of music. “You can download a song from iTunes to your iPhone or iPad, but at the moment music in that form doesn’t play to the strengths of the device. Just playing a track isn’t enough.”

Adam Liversage, a spokesperson of the British Phonographic Industry, which represents the major UK record labels, notes that the rise of streaming services such as Spotify may be a culprit in the fall in music sales. Revenues from such companies added up to $800m in 2009. Arthur feels that “again, it doesn’t make up for the fall in CD sales, but increasingly it looks like nothing ever will; that the record business’s richest years are behind it. Yet there are still rays of hope. If Apple – and every other mobile phone maker – are moving to an app-based economy, where you pay to download games or timetables, why shouldn’t recording artists do the same?”

Well, apparently they are. British singer Peter Gabriel has released a ‘Full Moon Club’ app, which is updated every month with a new song. Arthur also notes that “the Canadian rock band Rush has an app, and the industrial rock band Nine Inch Nails, led by Trent Reznor – who has been critical of the music industry for bureaucracy and inertia – released the band’s first app in April 2009.” It is thought that such a system will be an effective method to reduce online piracy—”apps tend to be tied to a particular handset or buyer, making them more difficult to pirate than a CD”, he says—and in the music industry, piracy is a very big problem. In 2008, the International Federation of the Phonographic Industry estimated that 95% of downloads were illegitimate. If musicians can increase sales and decrease piracy, Robert says, it can only be a good thing.

“It’s early days for apps in the music business, but we are seeing labels and artists experimenting with it,” Jacob said. “You could see that apps could have a premium offering, or behind-the-scenes footage, or special offers on tickets. But I think it’s a bit premature to predict the death of the album.” Robert concluded by saying that it could be “premature to predict the death of the iPod just yet too – but it’s unlikely that even Steve Jobs will be able to produce anything that will revive it. And that means that little more than five years after the music industry thought it had found a saviour in the little device, it is having to look around again for a new stepping stone to growth – if, that is, one exists.”

Saturn moon Enceladus may have salty ocean

Thursday, June 23, 2011

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.
