PITTSBURGH (AP) ? Ben Roethlisberger passed for two touchdowns and set a team record for career completions as the Pittsburgh Steelers crushed the error-prone Cincinnati Bengals 35-7 on Sunday.

Pittsburgh (9-3) swept the season series from Cincinnati (7-5) for the second straight year behind a 28-point explosion in the second quarter fueled by Roethlisberger, running back Rashard Mendenhall and a 60-yard punt return for a score by Antonio Brown.

Mendenhall and wide receiver Mike Wallace scored two touchdowns for the Steelers, who won for the seventh time in their last eight games.

Cincinnati rookie quarterback Andy Dalton threw for 124 yards and a touchdown to A.J. Green but the Bengals couldn't overcome two turnovers and a handful of special team gaffes to all but end their hopes of winning the AFC North.

(AP) ? Russians cast their ballots with muted enthusiasm in parliamentary elections Sunday, a vote opinion polls suggest could reduce the strength of Prime Minister Vladimir Putin's party. Rival parties and election monitors, which have suffered from government crackdowns, alleged significant violations at the polls.

Although Putin and his United Russia party have dominated Russian politics for more than a decade, popular discontent appears to be growing with Putin's strongman style, widespread official corruption and the gap between ordinary Russians and the country's floridly super-rich.

United Russia holds a two-thirds majority in the outgoing State Duma. But a survey last month by the independent Levada Center polling agency indicated the party could get only about 53 percent of the vote in this election, depriving it of the number of seats necessary to change the constitution unchallenged.

Putin wants United Russia ? which many critics now deride as the "party of crooks and thieves" ? to do well in the parliamentary election to help pave the way for his return to the presidency in a vote now three months away. He previously served as president in 2000-2008.

He has warned that a parliament with a wide array of parties would lead to political instability and claimed that Western governments want to undermine the election. A Western-funded election-monitoring group has come under strong official pressure and its Web site was incapacitated by hackers on Sunday.

Only seven parties have been allowed to field candidates for parliament this year, while the most vocal opposition groups have been denied registration and barred from campaigning.

Several parties complained Sunday of extensive election violations aimed at boosting United Russia's vote count, including party observers being hindered in their work.

Communist chief Gennady Zyuganov said his party monitors thwarted an attempt to stuff a ballot box at a Moscow polling station where they found 300 ballots already in the box before the start of the vote.

He said incidents of ballot-stuffing were reported at several other stations in Moscow, Rostov-on-Don and other areas. In the southern city of Krasnodar, unidentified people posing as Communist monitors had shown up at polling stations and the real observers from the party weren't allowed in, Zyuganov said.

In Vladivostok, voters complained to police that United Russia was offering free food in exchange for promises to vote for the party. In St. Petersburg, an Associated Press photographer saw a United Russia emblem affixed to the curtains on a voting booth.

Golos, the country's only independent election-monitoring group, said that in the Volga River city of Samara observers and election commission members from opposition parties had been barred from verifying that the ballot boxes were properly sealed at all polling stations.

Many violations involve absentee ballots, Golos director Liliya Shibanova said. People with absentee certificates were being bused to cast ballots at multiple polling stations in so-called "cruise voting."

Mikhail Kasyanov, a former prime minister during Putin's first presidential term, said he and other opposition activists who voted Sunday are under no illusion that their votes will be counted fairly.

"It is absolutely clear there will be no real count," he said. "The authorities created an imitation of a very important institution whose name is free election, that is not free and is not elections."

An interim report from an elections-monitoring mission of the Organization for Security and Cooperation in Europe noted that "most parties have expressed a lack of trust in the fairness of the electoral process."

United Russia's dominance of politics has induced a grudging sense of impotence among many in the country of 143 million. In Vladivostok, voter Artysh Munzuk noted the contrast between the desire to do one's civic duty and the feeling that it doesn't matter.

"It's very important to come to the polling stations and vote, but many say that it's useless," said the 20-year-old university student.

There are around 110 million eligible voters in Russia and turnout in many areas was lower Sunday compared to the previous election. In several far eastern regions and in Siberia turnout varied between 40 to 48 percent with two hours to go until the polls closed.

A few dozen activists of the Left Front opposition group tried to stage an unsanctioned protest just outside Moscow's Red Square on Sunday, but were quickly dispersed by police, who detained about a dozen of them. Later in the evening, police said they arrested more than 100 other opposition demonstrators in the capital and about 70 in St. Petersburg when they attempted to hold an unauthorized rally.

The websites of Golos and Ekho Moskvy, a prominent, independent-minded radio station were down on Sunday. Both claimed the failures were due to denial-of-service hacker attacks.

"The attack on the site on election day is obviously connected to attempts to interfere with publication of information about violations," Ekho Moskvy editor Alexey Venediktov said in a Twitter post.

Golos, which is funded by U.S. and European grants, has come under massive official pressure in the past week after Putin accused Western governments of trying to influence the election and likened recipients of Western aid to Judas.

Shibanova, the Golos leader, said its hotline was flooded Sunday with autonomically made calls that effectively blocked it. Prior to the vote, many of the group's activists were visited by secret police, while Shibanova was held for 12 hours at an airport and forced to hand over her laptop.

On Friday, the group was fined the equivalent of $1,000 by a Moscow court for violating a law that prohibits publication of election opinion research for five days before a vote.

U.S. Ambassador to Russia John Beyrle said in his blog that he called the Golos head Saturday "to express my support for the work they have been doing, and convey the concern of the White House about the pressure they have been experiencing over the last week."

The group has compiled some 5,300 complaints of election-law violations ahead of the vote, most of which are linked to United Russia. Roughly a third of the complainants ? mostly government employees and students ? say employers and professors are pressuring them to vote for the party.

(AP Photo/Steve Helber, File)

(AP) ? Virginia Tech says it acted appropriately in alerting the campus that bloody spring day in 2007 during what turned out to be the deadliest mass shooting in modern U.S. history.

The government disagrees and has levied $55,000 in fines, contending the school was too slow in notifying students, faculty and staff and therefore in violation of a federal law requiring timely warnings when there are safety threats.

The university gets a chance Wednesday to begin making its case before an Education Department administrative judge, Ernest C. Canellos, in hopes of erasing a fine that isn't hefty but can leave a black mark on an institution's record.

The fines were levied under a law known as the Clery Act, which requires colleges and universities to provide warnings in a timely manner and to report the number of crimes on campus. During the Obama administration, there's been a ramping up in enforcement under the act, which has gotten recent attention because of scandals at Penn State and Syracuse.

Investigators have been on the Penn State campus for a Clery Act investigation into whether the university failed to report incidents of sexual abuse in connection to allegations against former assistant football coach Jerry Sandusky. An Education Department spokesman said the department is also reviewing whether a similar investigation will take place at Syracuse. Three men, including two former ballboys, have accused former assistant basketball coach Bernie Fine of molesting them as minors.

In the Virginia Tech case, the rare hearing is expected to last two or three days. It probably won't end with an immediate ruling and further legal challenges could follow. Virginia Tech hasn't indicated it is backing down even though experts say schools found in violation of the law typically accept a fine and agree to changes or negotiate a settlement.

This has attracted great interest in higher education circles, given the high profile nature of the crime and the chance to learn how the department applies the law. The 1990 law was named after Lehigh University student Jeanne Clery, who was raped and murdered in her dorm room by another student in 1986.

During this administration, the Education Department has conducted more random Clery Act audits and has worked at times with the FBI. Six schools this year alone are facing fines, which is the same number that paid fines in the first 18 years of the law, said S. Daniel Carter, director of public policy at Security on Campus Inc., a Wayne, Pa.,-based organization formed by Clery's parents.

The maximum fine per violation under the law is $27,500. Colleges and universities can also lose the right to offer federal student loans, but that's never happened. In the highest fine issued under the Clery Act, Eastern Michigan University agreed in 2008 to pay $350,000 for covering up the rape and killing of a student in her dorm room by telling reporters and her parents there were no signs of foul play.

In the Virginia Tech case, the university opted to exercise its right for an appeals hearing before an Education Department administrative judge. Larry Hincker, a university spokesman, said in an email that the actions taken by Virginia Tech were well within the practices in effect then on campuses.

Virginia's attorney general, Kenneth Cuccinelli, said in a statement earlier this year that the appeal was filed to compel the department to treat Virginia Tech fairly. The university contends the department is holding it to a higher standard than what was in place at the time of the shootings.

"There are important principles and policies at stake here that affect not just Virginia Tech, but colleges and universities all across the country," Cuccinelli said in the statement.

The university is facing charges of failure to issue a timely warning and failure to follow its own procedures for providing notification.

"This case is about responsibility," the Education Department said in a court filing. "Specifically, it's about an institution's responsibility to provide vital information to its students and employees as required by federal law."

The department said the university violated the law by waiting more than two hours after two students were shot to death in a residence hall before sending out a campus wide warning by email. The department said the email was too vague because it mentioned only a "shooting incident" but did not say anyone had died. By that time, student gunman Seung-Hui Cho was chaining shut the doors to a classroom building where he killed 30 more people and then himself.

At the time the email was sent, the university has argued it was believed the two students were shot in an isolated domestic incident and that the shooter had left the campus. The school also contends it had planned a news conference to discuss the residence hall shootings until the later shootings intervened.

"This case is not one in which Virginia Tech was avoiding its responsibilities, but rather one in which it responded in a variety of ways that are permissible under the applicable regulations," the university said in a court filing.

Some family members of the students killed have called the fines woefully inadequate. Suzanne Grimes, whose son Kevin Sterne, was injured in the shootings, is scheduled to testify. She said in a telephone interview that university officials failed in their duty to warn students.

"The families of the deceased have a lifetime of grief and the survivors like my son, Kevin, have a lifetime of injuries and what the future holds for them, as a mother I'm concerned about," Grimes said.

Peter Lake, an education law professor at Stetson University College of Law, said higher education officials believe that what happened at Virginia Tech could happen on any campus. At the same time, university administrators are aware that enforcement of the Clery Act has increased, he said.

"It will be very interesting to see what the arguments are and how they are perceived," Lake said. "I think the field is very much on high alert. They are trying to figure out what's happening next."

While the Virginia Tech hearing may prove instructive for other schools on the Clery Act, a more applicable example on how such cases work involved a review at Tarleton State University in Stephenville, Texas, Carter said.

The Virginia Tech case focuses on what happened related to a specific incident, while Tarleton State's covered broader issues, which is more typical, Carter said.

The Education Department fined Tarleton State $137,500 in 2009 for allegedly underreporting the number of sexual assaults, burglaries and drug-related crimes on and near the campus between 2002 and 2007. The university appealed.

There wasn't an evidentiary hearing, but after reviewing the evidence, Canellos reduced the fine to $27,500. The case was appealed to Education Secretary Arne Duncan, who has not issued a decision.

Michigan State Spartans Take On Wisconsin Badgers In Big Ten Final

Free Press:

INDIANAPOLIS -- Michigan State coach Mark Dantonio knows Wisconsin is going to add new wrinkles to its offense. The Spartans have to be ready for whatever the Badgers have in store with Russell Wilson, the Big Ten's quarterback of the year, and Montee Ball, the conference's running back and offensive player of the year.

The teams meet for the second time this season tonight in the inaugural Big Ten championship game at Lucas Oil Stadium in Indianapolis with a Rose Bowl bid on the line.

"The play-action game (is) difficult with Wilson because he presents the run/pass conflict as well," Dantonio said Friday. "When we have trapped him in there, he's found a way to make play at times.

Despite Advances, HIV/AIDS Still Takes Heavy Emotional Toll (HealthDay)

THURSDAY, Dec. 1 (HealthDay News) -- For many it's a good news/bad news scenario.

People with HIV/AIDS are living longer and healthier lives than ever before, but they still have a chronic disease that's potentially fatal and carries a heavy stigma, said Jorie Barna, a care coordinator for the AIDS/HIV Services Group in Charlottesville, Va.

Barna, who lived in San Francisco during the 1980s and 1990s, said she saw the debilitating and deadly toll that HIV/AIDS took before the development of lifesaving antiretroviral medications.

"Living with HIV today is very manageable," said Barna, 43, who has a case load of 50 patients whom she monitors. "If somebody were to take care of themselves, eat well, keep their stress levels down, exercise regularly and take their medications, they could live long lives. I think in another decade, living with HIV will be like diabetes. You just have to take care of yourself."

Despite the medical advances, however, the mental toll that HIV/AIDS takes on people remains strong, Barna said, particularly in less-urban parts of the country.

"Stigma is still huge, huge here," she said. "A lot of people still associate HIV and AIDS as being a gay disease, which is not true at all. A lot of my straight men struggle because they don't want to be seen as homosexual."

Also, many of the people Barna helps were already at risk for infection because of other conditions.

"The issues that originally put them at risk for HIV infection have not been addressed," she said. "They're still struggling with mental health or substance abuse. They may be taking their medications and their HIV is stable, but they have other problems."

In addition, HIV/AIDS can have a severe financial impact on people, particularly if their infection was detected late and they've been incapacitated by it.

"People go on disability because they are too ill to work, but there's less and less out there for them," Barna said. "The government funding is drying up. It's hard to find affordable housing. There's no such thing as public transit here in Charlottesville. It's financially a huge challenge."

People with HIV/AIDS also come under additional stress from alienation and lack of affection, she said.

"It's hard on their families. It's hard on them," Barna said. "A lot of people feel they can't share their status with anyone. I have a lot of people who avoid physical intimacy, period, because they are afraid of disclosure. They are isolated and alone."

All of this adds to the tough medical struggle that HIV/AIDS patients face in dealing with their chronic illness.

"They might be physically stable enough, but they are still struggling emotionally, financially and psychologically," she said.

Downtown residential soil samples (in Cedar Rapids, Iowa, U.S.) found to contain industrial pollutants

ScienceDaily (Nov. 29, 2011) ? University of Iowa engineers have published their findings from a study of residential soils in the city of Cedar Rapids, making it one of only a few such U.S. urban soil studies ever conducted.

The authors of the study, published in the November online edition of the journal Environmental Pollution, collected soils in the residential areas of downtown Cedar Rapids and analyzed them for industrial pollutants known as PCBs (polychlorinated biphyenyls) and chlordanes. Measured values for both chemical groups were found to be similar to other urban/industrial sites around the world. Also, measured values were found to be of the same order of magnitude as the provisional threshold recommended by the U.S. EPA to perform soil remediation.

Project principal investigator Keri Hornbuckle, UI professor of civil and environmental engineering and researcher at IIHR-Hydroscience and Engineering, says that soil often stores residual amounts of persistent organic pollutants such as PCBs and chlordanes and -- because children and others can be be exposed on a regular basis -- contaminated soil may be a source of concern.

Hornbuckle notes that her study is somewhat unique because the few existing reports of chlordanes or PCBs in U.S. soil samples concern remote, unpopulated areas. In researching similar studies, she found only one study reporting chlordanes and two reporting PCBs for U.S. urban-residential soil concentrations. She adds that her study was aided by the fact that she grew up in Cedar Rapids and that several former Cedar Rapids teachers -- who were very familiar with the city -- assisted the team while sampling was being conducted.

During the historic floods of 2008, flooding of the Cedar River exceeded the historical record of flood discharge in Cedar Rapids and affected a large portion of residential, commercial, and industrial land in the city, including Cedar Lake. Having an average depth of less than four feet, Cedar Lake was long used as a cooling lake for the Sixth Street Generating Station and is contaminated with chlordanes and PCBs. It remains unknown whether the 2008 flooding caused any redistribution of those pollutants in the city, says Hornbuckle.

The UI study technique involved collecting 66 soil samples near Cedar Rapids streets on August 25, 2008 -- about 70 days after the flood. About 94 percent of the sampling sites were located inside the estimated flood area, and researchers concentrated on sampling sites south of Cedar Lake and west of the Cedar River. The total sampling area covered almost 4 square miles. Each sample involved collecting approximately 2 pounds of soil from a 5-inch-deep site using a trowel. The soil samples were placed in labeled, plastic Ziplock freezer bags and brought to the UI, where they were refrigerated prior to being analyzed -- using gas chromatography, mass spectrometry for chlordanes, and tandem mass spectrometry for PCBs.

Hornbuckle says that residents of Cedar Rapids and other cities should know that these chemicals are widely present in urban soils. She adds that we don't know the source of the PCBs found in Cedar Rapids soils, but that chlordane is probably present because homeowners used the insecticide to kill termites and that the original contamination probably occurred more than 30 years ago.

"Both these chemicals are now banned from production and sale, but are still in our environment because they are nearly nonbiodegradable," she says. "It is my opinion that we should not use chemicals that are so persistent in any household activity, but it is difficult for the average homeowner to know how to judge this. This data is not, but should be, provided on the containers of all the products we purchase."

Manufactured from about 1930 until being banned in the 1970s due to their toxicity and persistence in the environment, PCBs were widely used as coolants, in electrical transformers and in a wide variety of products ranging from waterproofing compounds to paints and pesticides. Chlordanes were used to control termites in buildings and as insecticides on lawns and gardens, as well as on corn and other crops, before the EPA banned their use in 1988.

The project was funded by the National Science Foundation (NSF) and as part of the Iowa Superfund Basic Research Program, which is funded by the National Institutes of Health.

The paper, titled "Spatial distribution of Chlordanes and PCB congeners in soil in Cedar Rapids, Iowa, USA," is scheduled for publication in the February 2012 print edition of the journal.

Hornbuckle's co-authors are Andres Martinez, Nicholas R. Erdman, Zachary L. Rodenburg, and Paul M. Eastling, all of the UI Department of Civil and Environmental Engineering and IIHR -- Hydroscience and Engineering. Of special note, Erdman and Rodenburg performed all chemical analysis required for the study while enrolled as UI undergraduate chemical and biochemical engineering students, and Eastling reported a draft of the study in his master's degree thesis in environmental engineering.
