Chinese boat captains arrested in Japan waters

Japan's coast guard says it has arrested two Chinese boat skippers in separate cases of suspected illegal fishing in Japanese waters.

Officials say a 39-year-old skipper was arrested Tuesday for alleged coral poaching off the Goto islands near Kyushu.

They say the second skipper was arrested Wednesday near the Ogasawara islands, 600 miles (1,000 kilometers) south of Tokyo. They said Thursday that both allegedly ignored calls to stop for inspection, prompting a chase.

If convicted, the skippers could face up to six months in jail or a fine of up to 300,000 yen ($3,840).

The incidents aren't likely to spark disputes as they didn't occur in contested waters.

Officials say Chinese poaching in and around Japan is on the rise.

Pimco market strategist: Europe still top threat (AP)

NEW YORK ? The bond market is said to be populated with worried, glass-half-empty types. And Pimco, the world's largest bond fund manager, is never shy about making the big picture look pretty bleak. The thing is, they keep getting it right.

Not long after the financial crisis hit in 2008, Pimco laid out a gloomy forecast for the years to come. Debt piled up over the boom years would drag down the U.S. and Europe, straining government finances to the breaking point. Markets wouldn't rebound as quickly as in the past. Pimco believed the rules of the game had changed.

Pundits and many investors attacked Pimco's view as overly pessimistic at the time. But a few years later, the European debt crisis, slow-moving economic growth at home and the turbulent stock market have turned Pimco's "new normal" into conventional wisdom.

So what's their view of the year ahead? Much like this year, everything hinges on Europe. In a recent interview with the Associated Press, Tony Crescenzi, a Pimco market strategist says the new year may look a lot like the old one. Investors should be prepared for the worst. In other words, don't rule out a collapse of the euro.

Q: How do you imagine 2012 will be different from 2011?

A: The world is playing a game of hot potato right now. There are more and more banks and investors seeking to sell assets and more assets seen as toxic. So you have more hot potatoes -- such as, European bank debt and European government debt. The only player with oven mitts is the European Central Bank, but it's refusing to be the lender of last resort. And at the same time, there are fewer and fewer places to hide from market volatility. Even gold in recent days has lost some of its luster as a store of value. This environment is likely to linger into 2012.

Q: Even after the recent agreement to put tighter controls on government budgets, you don't think Europe's debt crisis is anywhere near fixed?

A: Europe hasn't sought solutions that fix its current problems. Italy and Spain, their governments and banks combined, need around $500 billion in funding next year. That's a massive need. What if they don't get it? It creates a risky, volatile climate.

Q: This year, whenever Greece or Italy seemed to be struggling with their debts, everybody bought dollars and Treasurys and sold stocks. In 2012, do you expect markets will react like they did this year?

A: Like the second half of this year. That means people will be buying Treasurys. They'll be the big beneficiary again as people flee other assets. You want bonds that will behave well in a risky environment. For instance, Canadian government bonds, the U.K. gilt market, Australia, shorter maturities in the Brazilian market. And German government bonds, still.

In corporate bonds, it means underperformance. The dollar will continue to benefit as it has been recently. The dollar is up about 5 percent since July. We'd expect continued strength in the dollar.

Q: Pimco is buying U.S. Treasurys again. What else are you doing to prepare for this climate of uncertainty?

A: This is a time to be a true guardian of capital -- that's an expression Bill Gross (one of Pimco's founders) likes to use. You want to avoid catastrophic losses. And if there's a breakup of the euro there's a potential for catastrophic losses.

Within portfolios, we're choosing companies with strong balance sheets in strong industries. Second, we're also buying high in the capital structure. Meaning, that if there's a bankruptcy, you're first in line. Third, we're buying companies with hard assets to sell if there's a bankruptcy. Finally, we like to find products that are resistant to swings in demand. This isn't a recommendation but tobacco, for instance. That's a way to fortify a portfolio.

The point is to seek the return of capital not the return on capital. Stretching for additional yield may not be a fruitful endeavor. If you have to choose between a security that yields 3 percent versus one that yields 4, you might think "I'll take the 4 percent." But that's not enough. You need to look at the volatility. If the 4 percent security drops 30 percent in price, then you're burned.

Q: Pimco is widely credited with popularizing the idea that we're in a "new normal." Can you explain it in layman's terms?

A: It's the idea of seven years of abundance and seven years of famine. We had years of debt built up at the household level to buy homes, cars and other things. Now consumers are having to pay down their debts because they have too much relative to their incomes. Banks have had a similar situation. The deleveraging, this process of paying down debt, has shifted from the private sector to the public sector. You see this with the layoffs of teachers and other government workers. You'll see this more forcefully in 2013 when the federal government's automatic spending cuts kick in. There's going to be fiscal austerity that harms economic growth. It'll get worse. It's playing out already in Europe.

Q: Given all this austerity, do you expect interest rates to stay low?

A: Short-term interest rates aren't going anywhere. The 10-year Treasury yield is normally tied closely to the nominal gross domestic product. But the forecast for now is that conditions won't change much. And there's still a flight to safety seen very clearly in this week's Treasury auctions where demand has been extraordinary. I guess that leaves us in the 2 percent range for the 10-year (To put that in context, the 10-year Treasury rate started the year at 3.33 percent and traded at 1.85 percent on Friday).

Q: This is depressing. The new normal isn't the old normal yet, it's going to be with us for a while?

A: We're just in the early stages, in the very beginning of a long process. Look at Europe. People are up in arms about changes to benefits and services and public sector employment. It's the transformation of the century, really. The public sector is set to shrink globally.

It takes many years. But the final product is a much less risky financial system.

Portugal wavers on debt limit in Constitution (AP)

LISBON, Portugal ? Portugal's main opposition party held out Friday against the government's plan to include a budget deficit limit in the Constitution ? a step that is part of a broad European agreement to tackle the continent's debt crisis.

Portugal and most other European union countries agreed at a summit last week to amend their national constitutions, limiting deficits to 0.5 percent of economic output in regular economic times.

The measure, aimed at preventing government overspending, was part of a deal seen as vital to help end a financial crisis threatening European and global growth.

Portugal's center-right coalition government needs the support of the center-left Socialist Party to ensure the two-thirds parliamentary majority required for a constitutional amendment.

But Socialist leader Antonio Jose Seguro, whose party has endorsed austerity measures and reforms linked to a euro78-billion ($102-billion) international bailout earlier this year, refused to commit to constitutional changes.

He said during a parliamentary debate that Portugal should focus on "real solutions that address our problems." He did not elaborate though he has previously said a stricter budget law is enough to cap spending.

In an agitated parliamentary session, Prime Minister Pedro Passos Coelho said he had understood in private talks with the Socialists that they were open to negotiations on the proposal. Passos Coelho said if he had known the Socialists would dig their feet in, he would not have signed up to the EU agreement.

"Just as debts are meant to be paid, agreements are meant to be kept," Passos Coelho told lawmakers. "We can't keep going from summit to summit making promises that aren't kept," he said.

Lavish spending by previous Portuguese governments buried the country under a debt pile that spooked investors, forcing the country to ask for financial rescue. Portugal's deficit ? limited to 3 percent of gross domestic product under eurozone rules ? was 9.8 percent in 2010. Debt is expected to surpass 100 percent of GDP this year and peak at 106 percent in 2013 before retreating.

"We want to limit the ability of any government in office to compromise future generations," Passos Coelho said.

He told lawmakers his government will abide by the bailout deal despite a record 12.9 percent jobless rate and a double-dip recession that is forecast to deepen next year.

Is Arizona's Sheriff Joe a racist? (The Week)

New York ? The Justice Department is accusing tough-guy Sheriff Joe Arpaio of taking his hardline crusade against Latino immigrants too far

Sheriff Joe Arpaio of Maricopa County, Ariz., was handed an ultimatum on Thursday: Clean up his department's rampant and illegal racial discrimination or the federal government will see him in court. After a three-year investigation, the U.S. Justice Department accused the controversial immigrant-hunting sheriff of illegally jailing scores of Hispanic residents, often after trumped-up traffic stops; abusing Spanish-speaking inmates and denying them basic rights; and retaliating against critics. Arpaio shot back that the Obama administration was just using him as a "whipping boy," and supporter Gov. Rick Perry (R-Texas) darkly warned, "I would suggest to you that these people are out after Sheriff Joe." Do Arpaio's fans have a case, or is self-proclaimed "America's Toughest Sheriff" really just "America's Most Racist Sheriff"?

Racism is just the tip of the iceberg: The DOJ's damning report confirms what we already suspected, says Lucy Steigerwald in Reason: Sheriff Joe is an "awful person" whose brutal tactics indiscriminately target Latinos, including U.S citizens. And while he excels at violating Latinos' "civil rights and the Constitution," Arpaio is "really awful at following up on serious criminal complaints," like 400 sex-abuse reports, mostly involving Latino victims. "Schadenfreude should reign throughout the land" at this racist jerk getting busted.
"The Department of Justice is very unhappy with Joe Arpaio"

Obama is out for Arpaio's head: There are some "serious" concerns raised in the report, and those "should be looked into," says 24Ahead.com. But even after a "politically motivated quasi-witchhunt," Team Obama unearthed "no smoking gun in the entire report against Arpaio himself." The feds are going after Sheriff Joe because he is "interfering with attempts by crooked businesses to make money [off illegal immigrants] and with corrupt politicians' attempts to obtain race-based power."
"DOJ investigation claims Sheriff Joe Arpaio engaged in 'unconstitutional policing'"

Racist or not, he'll be sheriff for awhile: Arpaio's sheriff's office, as detailed by the DOJ, really is "appalling. It's disgusting. It's infuriating," says E.J. Motini in The Arizona Republic. But this is hardly the first time "we've heard tough talk about Arpaio from federal officials." Nothing ever comes of it, and it's unlikely the Obama administration will bring much change to Sheriff Joe's bailiwick, either. After all, for 20 years "he's gotten re-elected for doing pretty much what Justice officials say he shouldn't be doing."
"Despite all the tough talk, Joe Arpaio is still sheriff"

Russian security council chief wants Web regulation (Reuters)

MOSCOW (Reuters) ? The Internet must be subject to "reasonable regulation," the head of Russia's Security Council said in remarks published on Wednesday, a fresh sign of Kremlin concern about the use of social networks to promote anti-government protests.

Opposition groups and ordinary Russians used Facebook and the Russian site VKontakte to organize protests last week over a December 4 parliamentary election they charged was rigged to benefit Prime Minister Vladimir Putin's ruling party.

Tens of thousands of people rallied on Saturday in the biggest anti-government protests since Putin came to power 12 years ago, many chanting "Russia without Putin!"

Opponents plan further protests ahead of a March election expected to return Putin, a former Soviet KGB officer and Russian Federal Security Service (FSB) chief, to the presidency.

"Attempts to stop people from communicating are in principle counterproductive and even amoral," Security Council secretary Nikolai Patrushev, who headed the FSB during Putin's 2000-2008 presidency, told the daily Argumenty i Fakty.

"However, one must not ignore the use of the Internet by criminals and terrorist groups. Reasonable regulation, of course, must be conducted in Russia, as is done in the United States, China, and many other countries," he said.

Chinese government controls on the Internet are far stricter than those in the United States, and Patrushev gave no details in the newspaper interview, but his remarks suggest Russian authorities are considering ways of reining in the Internet.

Putin has publicly said that the state's ability and right to control Internet use is limited, and suggested his government would not try to do so. Analysts say hardliners close to Putin would like to impose controls similar to China's.

Vkontakte, Russia's top social networking site, said last week that it had rejected a request by the FSB to block opposition groups from using it to organize street protests.

A spokesman for VKontakte, used by tens of thousands of people to coordinate support for the December 10 protests, said the company was not pressured or threatened.

Ahead of the parliamentary vote, however, the websites of the independent election monitoring group Golos and at least two media outlets that had aired reports of alleged campaign violations were blocked by denial-of-service attacks.

The head of Golos, a Western-funded group that has a site with a map showing reported cases of electoral violations, said she suspected the FSB was behind the attacks.

Russian officials have expressed concern about the powerful role of online communication in the unrest that has brought down governments in the Arab world in the past year.

A senior FSB officer said in April that uncontrolled use of Gmail, Hotmail and Skype were "a major threat to national security."

Performance Analysis of Adaptive ARQ Protocol Base on ...

Abstract

Wireless communication systems have a high error rate because the time-varying nature and multi-path transmission characteristics of the wireless channel and a variety of noise interference. Therefore, effective error control technology is a key issue in wireless communication. Compare with the forward error correction (FEC), the automatic retransmission request (ARQ) error control technology is more reliable, which is one very effective error control technology in wireless high-speed communications.In this paper, some research work about the ARQ error control protocol has be done, the protocol may be used in the infrared communication networks or used in the multimedia communications network. In chapter 2, broadband wireless multimedia communication as the research background, we mainly consider that how to design retransmission scheme to make the reliability and real-time of data reached an acceptable level, when the transmission delay is demanded strictly and the data must be more reliable. An adaptive ARQ protocol (SG-ARQ) which combined ARQ with SR and GBN is proposed for broadband wireless multimedia communication. With using the SG-ARQ protocol, the system delay and packet drop rate are controlled efficiently, the data reliability is improved and system throughput is increased. Besides, the delay of SG-ARQ system is analyzed by using queuing theory, the packet drop rate and throughput is analyzed also, and the general expressions of performance indexes are obtained. Numerical results show that the adaptive ARQ protocol can obtain better performance than any other general ARQ in broadband wireless multimedia communication. In chapter 3, at first, several basic ARQ technology are introduced, the development of infrared communication and its features and principle are described. Following, the GBN-ARQ protocol are analyzed separately when it works in half-duplex communication system and in the duplex communication system, and the similarities and differences are compared. Finally, established vacation queue model for the GBN-ARQ system which work in half-duplex mode using queuing theory, and express the factors which affect the transmission system with proper parameters according the property of half-duplex links, analyze the component of average packet delay by using queuing theory, ordinary expression of average packet delay is obtained, which contain average packet waiting delay and packet service delay. The influence of packet error rate, windows length and data packet length on system delay is analyzed by numerical simulation. The results show that the relations of packet correct rate, packet length, the sending window size have significant impact on the system delay. So, the system transmission efficiency will be improved effectively, if the relationships of the three variables are determined reasonably.
