Bruce, Canberra — This past week, an overstocked Australian Opals, the women’s national basketball team, prepared for the 2012 Olympic Games in London with a weeklong training camp at the Australian Institute of Sport (AIS) to be used to help narrow the nineteen member Opals squad down to the twelve that go to the Games, and provide players who rarely play together an extended period of time to play together in order to improve on court dynamics.

Camp started on Sunday, with players arriving from hometowns around Australia including Cairns, MacKay, Gladstone, Brisbane, Adelaide, and Melbourne.

The defending champions, the United States women’s national basketball team, are perceived as the Australian Opals’ main competitors. In the last three Olympic Games the Opals got silver medals. In each of these cases the United States got first place. Coach Carrie Graf said “thinking about the US too soon in inappropriate”, “Our focus is first and foremost, game by game winning our pool”. Amongst the Australian Opals’ competitors in the pool are Brazil, Russia, and Great Britain. Carrie Graf said Great Britain “will put up a fight on home turf” but there is a “world class [AIS] facility” and “world class medical support staff” supporting the team.

Australian Opal player Penny Taylor recently suffered injury from a torn anterior cruciate ligament, meaning she cannot play Olympics this year. In regards to the situation player Lauren Jackson, who is going into her fourth Olympics, said “you would never wish that upon anybody.” She says as a team they have to “move on, move through that” and “come together” to pick up their offence and defense. Despite the loss of one of their key players she says “we definitely have the talent there” and the team is all “on the same page.” She feels “pretty confident” and speaks of “very exciting” times ahead. Jenna O’Hea is going into her first Olympics with the team. She is still “pinching” herself and says she is taking it “day by day”.

A typical day at the camp might start with a 7.00am – 8.30am breakfast at the AIS Dining hall, before one and a half or two hours of court, gym, or swimming training. The middle of each day might consist of media meetings, medical checks, team meetings, and time to practise shooting. Around 12.00pm, the players meet to eat lunch and recover from the morning. The afternoon typically consists of more training, and some scrimmage games. Players usually finish around 7.00pm for dinner, and perhaps a massage.

The nineteen players in attendance this week at training camp were Suzy Batkovic, Abby Bishop, Elizabeth Cambage, Rohanee Cox, Cayla Francis, Kristi Harrower, Laura Hodges, Natalie Hurst, Lauren Jackson, Rachel Jarry, Kathleen MacLeod, Jenna O’Hea, Samantha Richards, Jennifer Screen, Belinda Snell, Marianna Tolo, Kristen Veal, Carly Wilson, and Hanna Zavecz. Basketball Australia has named fifteen players that are to attend the second phase of the camp: Suzy Batkovic, Abby Bishop, Elizabeth Cambage, Kristi Harrower, Laura Hodges, Lauren Jackson, Rachel Jarry, Kathleen MacLeod, Jenna O’Hea, Erin Phillips, Samantha Richards, Jennifer Screen, Belinda Snell, Marianna Tolo, and Hanna Zavecz.

In response to recent accusations that United States government employees have engaged in Wikipedia vandalism and other forms of perceived negative editing of articles, Wikipedia editors have set up a webpage listing all Wikipedia edits made through IP addresses that are allocated to the United States House of Representatives and other United States government agencies. The House IP address was briefly banned from editing Wikipedia articles in the wake of the initial controversy, but the ban was lifted on January 30 after Wikipedia administrators decided that there have been a number of valuable contributions made through the House and Senate IP addresses in addition to the controversial edits.

On January 31 and February 1, however, the U.S. House of Representatives’ common IP address, 143.231.249.141, were banned again for three hours due to vandalism. Because the IP address is shared by House staff members, it is uncertain whether or not the same person(s) responsible for the previous vandalism are also responsible for the latest.

Examples of contributions submitted through the House IP address included removing, “In 2005, he has come under scrutiny for accepting campaign contributions from embattled former house leader Tom Delay,” from the article on Thad McCotter, removing election statistics from the article on Dan Lungren, and, in the article on Marilyn Musgrave, changing the paragraph

“As a state legislator, Musgrave spent much of her time on social issues, particularly authoring bills to deny marriage rights and parental rights for gay and lesbian families. One of her final, failed bills would have made it much more difficult for same-sex parents to see their children in the hospital during an emergency. Musgrave also cast the only vote against legislation to give battered spouses paid leave from work.”

to

“As a state legislator, Musgrave spent much of her time on social issues, particularly authoring bills to protect children and the traditional definition of marriage, as well as gun owner’s rights.”

After the block from Wikipedia expired, the House of Representatives user continued to edit the article on Chris Shays. Chris Shays had co-sponsored a bill with Marty Meehan, whose staffers had previously been found to have been negatively editing Wikipedia entries, The American Civil Liberties Union said of the bill “key elements of Shays-Meehan violate the First Amendment right to free speech because the legislation contains provisions that would violate the constitutionally-protected right of the people to express their opinions about issues through broadcast advertising if they mention the name of a candidate.” All mentions of the bill were removed from the article. Also removed was a paragraph about Chris Shays raising $70,000 with House Speaker Dennis Hastert at a country club event.

Again, the IP address was blocked for an eight-hour period.

Wikipedia edits in Congress are not coming from the House of Representatives alone. An edit from the Senate in July removed references to a plagiarism scandal with Senator Joe Biden, who has informally said he may seek a Democratic nomination for president in 2008. As of February 4, 2006, the edit has not fixed by Wikipedia users.

IP addresses from the CIA, the Department of Justice, the Marines, and the Navy are listed on the site as having made several cases of vandalism. Some examples of vandalism from the Department of Justice IP ranges involve articles on TV and radio shows, a baseball player, or just complaining about their work. In addition to accusations of vandalism, there have also been accusations of government employees introducing perceived bias, political spinning, or misinformation into Wikipedia articles by adding or removing information.

These cases include articles on an Irish politician, and in the George W. Bush article, introducing accusations of Hugo Chavez being a dictator, and removing information covering the George W. Bush substance abuse controversy. In addition, a person using a Department of Justice IP address edited a page covering indicted former Republican Majority Leader Tom DeLay. The editor removed two paragraphs stating a judge ruled that Tom DeLay had broken state law by not disclosing over $600,000 of fundraising money, a quote from Tom DeLay in which he stated that it drives the Democrats crazy wondering why the Republican Party institutes pro-Israeli policy, and a subsection on controversies involving DeLay’s relatives. Edits to George W. Bush’s article were done within the span of an hour. Edits to Tom DeLay’s article were made within an hour as well, although followed by a shorter, minor second session of editing later that day.

An editor using a CIA IP address is accused of vandalizing an article on the current president of Iran. Editors using Marine and Navy IP addresses based in Pensacola, Florida are accused of vandalizing an article on a rock song and on former U.S. president Bill Clinton, and accused of adding racist comments to articles on an actor and Martin Luther King, Jr., and adding comments that are perceived to criticize the men and women in the Navy reserves.

The IP addresses of the Department of Justice, the CIA, and the Navy and Marines stationed in Pensacola, Florida were found using the American Registry for Internet Numbers at the official website. Neither the government nor the Wikimedia Foundation have released an official statement.

The U.S. House of Representatives’ IP address is not the first governmental address to have been blocked after accusations of disrupting Wikipedia. The IP address belonging to a subdivision of the Ministry of Agriculture, Food and Rural Development in Alberta, Canada was blocked for three months since late 2005. An IP address belonging to the German Bundestag has been repeatedly blocked from the German Wikipedia after accusations of vandalism, including sexually explicit comments.

More than 50 programmers, scientists, students, hobbyists and fans of the A.L.I.C.E. chat robot gathered in Guildford, U.K. on Friday to celebrate the tenth birthday of the award winning A.I. On hand was the founder the Loebner Prize, an annual Turing Test, designed to pick out the world’s most human computer according to an experiment laid out by the famous British mathematician Alan Turing more then 50 years ago. Along with A.L.I.C.E.’s chief programmer Dr. Richard S. Wallace, two other Loebner prize winners, Robby Garner and this year’s winner, Rollo Carpenter, also gave presentations, as did other finalists.

The University of Surrey venue was chosen, according to Dr. Wallace, not only because it was outside the U.S. (A.L.I.C.E.’s birthday fell on the Thanksgiving Day weekend holiday there, so he expected few people would attend a conference in America), but also because of its recently erected statue of Alan Turing, who posed the famous A. I. experiment which inspired much of the work on bots like A.L.I.C.E. University of Surrey Digital World Research Centre organizers Lynn and David Hamill were pleased to host the event because it encourages multi-disciplinary interaction, and because of the Centre’s interest in interaction between humans and computers.File:ALICE Birthday Cake.jpg

Dr. Wallace gave a keynote address outlining the history of A.L.I.C.E. and AIML. Many people commented on the fact the he seemed to have moved around a lot in the last ten years, having lived in New York, Pennsylvania, San Francisco, Maine, Amsterdam and Philadelphia, while working on the Alicebot project. The A.L.I.C.E. and AIML software is popular among chat robot enthusiats primarily because of its distribution under the GNU free software license. One of Dr. Wallace’s PowerPoint slides asked the question, “How do you make money from free software?” His answer: memberships, subscriptions, books, directories, syndicated ads, consulting, teaching, and something called the Superbot.

Rollo Carpenter gave a fascinating presentation on his learning bot Jabberwacky, reading from several sample conversations wherein the bot seemed amazingly humanlike. Unlike the free A.L.I.C.E. software, Carpenter uses a proprietary learning approach so that the bot actually mimics the personality of each individual chatter. The more people who chat with Jabberwacky, the better it becomes at this kind of mimicry.

In another interesting presentation, Dr. Hamill related present-day research on chat robots to earlier work on dialog analysis in telephone conversations. Phone calls have many similarities to the one-on-one chats that bots encounter on the web and in IM. Dr. Hamill also related our social expectations of bots to social class structure and how servants were expected to behave in Victorian England. He cited the famous Microsoft paperclip as the most egregius example of a bot that violated all the rules of a good servant’s behavior.

Bots have advanced a long way since philanthropist Hugh Loebner launched his controversial contest 15 years ago. His Turing Test contest, which offers an award of $100,000 for the first program to pass an “audio-visual” version of the game, also awards a bronze medal and $2000 every year for the “most human computer” according to a panel of judges. Huma Shah of the University of Westminster presented examples of bots used by large corporations to help sell furniture, provide the latest information about automotive products, and help customers open bank accounts. Several companies in the U.S. and Europe offer customized bot personalities for corporate web sites.

Even though Turing’s Test remains controversial, this group of enthusiastic developers seems determined to carry on the tradition and try to develop more and more human like chat bots.Hugh Loebner is dedicated to carry on his contest for the rest of his life, in spite of his critics. He hopes that a large enough constituency of winners will exist to keep the competition going well beyond his own lifetime. Dr. Wallace says, “Nobody has gotten rich from chat robots yet, but that doesn’t stop people from trying. There is such a thing as ‘bot fever’. For some people who meet a bot for the first time, it can pass the Turing Test for them, and they get very excited.”

Continuing a trend of steady employment growth, the United States economy added 215,000 jobs in July, the Bureau of Labor Statistics said on Friday. The unemployment rate remained unchanged at 5.3%.

“Job growth is quite strong,” stated Jim O’Sullivan, chief economist at High Frequency Economics, a data analysis firm in New York. “This pace of employment growth is clearly strong enough to keep the unemployment rate trending down.”

Average hourly earnings rose 0.2%, marking a rebound after growth stalled in June. Wages have grown by 2.1% over the past year, below the Federal Reserve’s target of 3.5% annual wage growth, and not much more than the underlying rate of inflation.

While sluggish wage growth remains a pocket of weakness in the economic recovery, steady payroll gains averaging 242,000 per month over the past twelve months have led observers to consider a Federal Reserve interest rate hike as increasingly likely, according to The New York Times.

“We view this report as easily clearing the hurdle needed to keep the Fed on track for a September rate hike,” said Rob Martin, an economist at Barclays in New York. “The bar for not moving now is much higher.”

Although the Federal Reserve has not explicitly stated that they plan to raise interest rates in the near future, the US central bank has stated that it would raise rates when it has seen “some further improvement” in the jobs market. The Fed has not increased interest rates since 2006, and during the 2007-2009 recession, it lowered rates to historically low levels.

Officials from France’s aviation accident investigation agency, the Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), announced on Tuesday that they had recovered the cockpit voice recorder (CVR) of Air France Flight 447. It was located and brought to the surface by a Remora 6000 unmanned submarine, then taken aboard the Île de Sein, one of the vessels taking part in the recovery and salvage efforts.

This came two days after an announcement on Sunday that the crash-survivable memory unit of the flight data recorder (FDR) of the aircraft had been located and brought to the surface. The chassis of the FDR was located on April 27, with the memory unit missing. It was found a short distance from the chassis. It was also brought to the surface by the Remora 6000.

With the recovery of both recorders, which are reported to be “in good condition”, French officials hope to determine what caused the Airbus A330-200 to crash into the Atlantic Ocean on June 1, 2009, when it departed Rio de Janeiro’s Galeão International Airport before it was lost 600 miles (965 km) off the coast of Brazil en route to Paris’ Charles de Gaulle Airport with 228 passengers and crew on board.

The leading theory at the moment is that the crew received incorrect air speed readings from the aircraft’s pitot tubes, devices which measure how fast the aircraft is traveling. Experts say the tubes may have become iced over, causing the crash. The plane’s Aircraft Communications Addressing and Reporting System (ACARS) sent out 24 messages over a four-minute long period stating numerous problems and warnings, including incorrect air speed warnings occurring aboard the aircraft, just prior to it going down.

However, chief operating officer of the International Bureau of Aviation, Phil Seymour, speaking to CNN, believes the memory unit will not be of much use to investigators saying because of the depth it was located at, “If you were to throw a computer into the ocean, imagine how all the parts would eventually split and you have the corrosive effects of seawater and the depths involved.” Seymour believes the wreckage will help reveal what happened as more is recovered.

“It may be that the more wreckage they find will help them to piece it all together, which bit by bit could help them build a picture of what caused the plane to come down,” he added.

A BEA spokesperson had agreed with that possibility a few days earlier when speaking to the Associated Press about the recovery of the flight data recorder. “We can’t say in advance that we’re going to be able to read it until it’s been opened,” the spokesperson said. As

The wreckage of the Airbus A330-200, was found back on April 8 at a depth of 3,800 and 4,000 meters (2,070 to 2,190 fathoms or 12,467 feet and 13,123 feet), by a team from the Woods Hole Oceanographic Institution, using a Remus robotic submarine and its side-scan sonar. After the wreckage was found, another Remus robot submarine with cameras was sent down to the site, where it filmed bodies in the wreckage. The location of the recorders were localized within 2 square miles (5 square kilometers) of the flight’s last position last year.

In March, a French judge placed the European aircraft maker Airbus and Air France under investigation for possible involuntary manslaughter charges in the 2009 crash. Both are paying the cost of the search which is estimated to be $12.7 million (nine million euro). The crash is the deadliest in Air France’s history.
