Inter-county communications - The RadioReference.com Forums

I remember when I was monitoring in Missouri 25 years ago, that when counties needed to communicate with each other, they would use the point-to-point frequency of 155.370. I think that here in Arkansas they used 37.240, correct?

Anyway, obviously they still communicate with each other, but not via radio. Are they using teletype? Email? How do counties communicate information with each other?

Italian astrophysicist Margherita Hack dies at 91

ROME (AP) ? Margherita Hack, an astrophysicist who explained her research on the stars in plain language for the public and who championed civil rights in her native Italy, died on Saturday in the Adriatic Sea town of Trieste, where she had headed an astronomical observatory. She was 91.

President Giorgio Napolitano's condolence message hailed her as a "high-level personality in the world of scientific culture."

"At the same time, she represented a strong example of civil passion, leaving a noble fingerprint in public debate and in the dialogue with citizens," Napolitano said.

The Italian news agency ANSA quoted family friend Marinella Chirico as saying Hack died in a hospital after being treated for heart problems.

Hack headed the observatory in Trieste, the first woman to hold that post, from 1964 to 1987, and was a popular and frequent commentator in Italian media about discoveries in astronomy and physics.

The current director of the observatory, Stefano Borgani, told Sky TG24 TV that Hack was one of the first astronomers to "have the intuition" that the future of astronomical observation lay in using space satellites.

An atheist who decried Vatican influence on Italian politicians, Hack helped fight a successful battle to legalize abortion in Italy. She unsuccessfully lobbied for the right to euthanasia and also championed gay rights. Among her victories was a campaign against construction of nuclear reactors in Italy.

A vegetarian since childhood, she also was an advocate for animal protection and lived with eight cats and a dog.

Hack, an optimist with a cheerful disposition, studied the heavens in the firm belief there was no after-life.

"I have no fear of death," Hack once said in a TV interview. "While we are here, death isn't" with us.

"When there is death, I won't be here," she said.

Among the many Twitter comments about her passing was one from an admirer who wrote that Hack was "so great and nice that God will pretend not to exist so as not to upset her," the Italian news agency LaPresse noted.

She liked to joke that the "first and last" time she was in a church was for her marriage to fellow native Florentine Aldo De Rosa, in 1944. She agreed to a church ceremony only because the groom's parents were very religious. Hack dressed simply in life, including for her own wedding, when she wore an overcoat-turned-inside out for a bridal gown. She and her widower, 93, had no children.

Hack enrolled at the University of Florence as a student of literature, but after one class, switched to physics. By the early 1950s, she was an astronomer at the Tuscan city's astronomical observatory.

She was also an athlete, excelling in track. Specializing in the long jump and high jump from 1939 to 1943, she won national university championships and placed high in national championships.

Hack was active in left-wing politics, including most recently supporting the governor of southern Puglia, Nichi Vendola, one of Italy's few openly gay politicians.

"With Margherita Hack's passing, we lose an authoritative voice in favor of civil rights and equality," said Fabrizio Marrazzo, a spokesman for a gay advocacy group, Gay Center. "More than once, Hack came out in favor of gay rights, civil unions and the dignity of gay families."

Italy's foreign minister, Emma Bonino, who as a leader of the tiny Radical Party helped wage battles to legalize divorce and abortion in Italy, said Hack was "an extraordinary figure."

"With her vanishes not only a great scientist but a free spirit, deeply intellectually honest," ANSA quoted Bonino as saying.

(AP) ? Riders set out Saturday on stage one of the 100th Tour de France with British sprinter Mark Cavendish among the favorites to take the first yellow jersey and race favorite Chris Froome overcoming an early technical problem.

Starting from the harbor town of Porto Vecchio, the flat 132-mile stage first took riders inland before snaking along the Corsican coast to finish in Bastia.

The race has usually started with a short prologue stage where riders raced against the clock. But in a break with tradition, this year's opener favors sprinters like Cavendish and rival Peter Sagan of Slovakia.

With defending champion Bradley Wiggins not competing, Froome of Britain and Spaniard Alberto Contador start as the main favorites for the three-week, 2,115-mile race.

Froome, the most highly regarded climber in the Tour, stopped to get a new rear wheel after a mechanical incident about five kilometers (3 miles) into the race. He then stopped for a second time to get a new bike shortly after before his Sky teammates helped him rejoin the main pack.

It is the first Tour since disgraced former cyclist Lance Armstrong was stripped of his seven straight Tour titles from 1999 to 2005 for doping.

Armstrong still managed to hog the headlines on the eve of the race, though, infuriating riders both past and present by talking at length in a newspaper interview about doping in the sport and sparking a media frenzy that organizers could have done without as they desperately try to turn the page on doping and restore credibility and trust.

In answering questions from Le Monde, a newspaper he scorned when he was still competing, Armstrong said it was impossible to win the Tour during his era without doping, echoing what he already told U.S. television talk show host Oprah Winfrey in January when he finally confessed to years of drug cheating after denying it for so long.

Before the stage started, French Sports Minister Valerie Fourneyron met with a delegation of riders unhappy about pre-race media reports that they thought focused too heavily on doping stories.

Earlier this week, French media reported that a Senate investigation into the effectiveness of doping controls pieced together evidence that a urine sample provided by long-beloved French rider Laurent Jalabert contained EPO, cycling's designer drug, at the Tour of 1998.

Meanwhile, two-time champion Contador returns to the race following a doping ban that saw him stripped of his 2010 title. He has always denied doping.

It is the first time since 1966 that the first stage has been tailor-made for sprinters, with the prologue introduced to the race in '67.

With Wiggins pulling out about a month before the race because of a knee injury, Froome is the odds-on favorite to become the second Briton to win the showcase race.

The 28-year-old has had a great run-up to the Tour, winning four of five races he started.

Kat Von D and Deadmau5 reveal split over Twitter

After their split, Kat Von D and Deadmau5 both took to their social media accounts to tell their sides of the story.

Kat Von D and Deadmau5's engagement started over Twitter, so it's only appropriate that they would discuss their break up on the social network site.

The couple, who have been engaged since December when the DJ sent a proposal to Von D via Twitter, have called it quits over allegations that he cheated.

Von D posted a cryptic tweet on Wednesday, and later followed it up with a second tweet that gave her more than 1 million Twitter followers a bit more detail on her current situation.

For his part, Deadmau5 (real name Joel Zimmerman) is denying he ever cheated, offering his Facebook fans and Twitter followers his own version of what went down:

At the end of June, it was clear that the relationship was not working and we mutually ended the engagement. I was not, at any point, unfaithful to Kat during our time together.

In the Facebook post, Deadmau5 admits that he did have "relations" with another woman before he proposed to Von D, but claims that it happened while he and the former reality personality were broken up.

Von D certainly hasn't been lucky in love. This is the third failed engagement for the tattoo artist in two years. She was previously engaged -- twice! -- to motorcycle builder and reality star Jesse James. Before that, she was married to fellow tattoo artist Oliver Peck from 2004 to 2007.

Huhne, hubris and home improvement: the failure of the 'green deal'

All politicians want some kind of legacy. They seek a footnote in the annuls, just to prove that all those compromises and disappointments were not in vain. Chris Huhne?s legacy is that his name is synonymous with the criminal act of passing off your speeding points to someone else. It?s a legacy of a sort.

Huhne wanted his legacy to be, not an entry into the dictionary of urban slang, but as a great reforming energy secretary. At the heart of his programme was the ?green deal?, a scheme to insulate homes and businesses, thus cutting their heating bills and more importantly, their carbon emissions. It was broadly similar to a scheme Labour had been piloting, and to one which appeared in Labour?s 2010 manifesto as ?Pay as You Save?.

Here?s what Chris Huhne told the Liberal Democrat conference in 2010, in the first flush of coalition amour:

?The Green Deal will be a revolution. The first scheme of its kind in the developed world. The most ambitious energy-saving plan ever put forward. A once-and-for-all refit that will make every home in Britain ready for a low-carbon future. No more half-measures going off at half-cock.?

Most ambitious ever. Every home. No more half-measures. When the Greeks invented hyperbole, they meant it to be used for emphasis, not literally. Huhne was not being hyperbolic; he meant it. His audience of Liberal Democrat activists clapped like seals as the man most them had voted for in the leadership contest declared the End of Global Warming

A few weeks later he told an audience at the London School of Economics: ?Over the next two years we expect to insulate 3.5 million homes?. He went on: ?The number of people employed in insulation alone could soar from 27,000 to 100,000 by 2015. That could eventually rise to a peak of 250,000.?

It couldn?t be clearer: 3.5 million homes insulated by 2012, and 100,000 jobs by 2015. And lest you think this was merely Chris Huhne?s vaunting ambition and loose grip of reality getting the better of him, the rhetorical baton was picked up by his fellow ministers. Energy Minister Greg Barker has declared the Green Deal will be ?transformational?. In March this year, Barker told BBC Radio 4: ?I wouldn?t be sleeping if we didn?t have 10,000 at the end of the year.?

Yesterday, we had the first proper analysis of how the Green Deal is doing. I?ve sat in a few meetings where ministers are given bad news by their officials. I imagine the conversation went something like this:

Official: ????????? ?Minister, there?s good news and there?s bad news on the Green Deal. The good news is that people are taking up our offer of finance schemes to insulate their homes. The Green Deal is up and running. Congratulations, Minister.?

Minister: ??????? ?And the bad news??

Official: ????????? ?ah yes, the bad news is that he haven?t quite hit our targets. Still, it?s early days. Rome wasn?t built in a day. Nil desperandum.?

Minister: ??????? ?How many??

Official: ????????? ?Four?

Minister: ??????? ?Just four? That?s terrible. I promised millions. Four thousand is a dreadful start.?

Official: ????????? ?not 4,000, minister, just four. We have their names and addresses here on this post-it note.?

Four households have had insulation under the Green Deal. Not one single household has fully completed work under the Green Deal. Most of the money allocated ? ?250,000 out of a potential pot of millions ? has been for boiler upgrades, mostly for people who could have afforded it anyway.

Greg Barker told the Guardian that ?Eight million solid wall homes have had no affordable solution to insulate. The green deal will change that.? How many solid walls have had insulation under the Green Deal? One. Strictly speaking, going from zero to one does count as ?change?, but it?s not quite eight million.

It?s a catastrophic cock-up on a grand scale. A failure of Titanic proportions. It is the R101 of public policy. It also suggests that even ministers, their advisers and officials have failed to take up the Green Deal. Making Lib Dem MPs do it would have boosted the numbers. Even they consider it a waste of time.

It may look like farce, but the tragedy is that it needn?t have been like this. Labour?s front-bench energy team have consistently and loudly warned that the policy was badly-conceived and likely to fail. At Labour?s 2011 conference, shadow energy secretary Meg Hillier warned of a ?green deal that promises the earth, but few have even heard of.? Her successor as shadow energy secretary Caroline Flint has consistently warned that the scheme would fail. Shadow energy minister Luciana Berger has harried ministers over the details of the scheme: the failure to secure business backers, the high interest rates on repayments, and the failure to adequately restrict con artists and cowboys.

So three years on from Huhne?s ridiculous speeches about the ?step change? in home insulation, we are left with fewer homes and businesses than ever with adequate insulation, no new job opportunities and Britain even further away from meetings its international obligations on climate change.

A serious piece of work needs to be done on what went wrong, perhaps by the Institute for Government, or some such independent body. It?s a case study in public policy failure. But the real job now is for Labour to outline an alternative programme. We will inherit a mess, but we will need to clear it up quick. A new, fair, affordable finance regime, less reliance on private suppliers, more use of local authorities, a bigger marketing budget: whatever the answers are, we need to articulate them quickly. Shadenfreude doesn?t win any votes; a practical scheme to insulate peoples? homes and save them cash, delivered without any Huhne-esque hubris, will.

New brain imaging study provides support for the notion of food addiction

June 26, 2013 ? Consuming highly processed carbohydrates can cause excess hunger and stimulate brain regions involved in reward and cravings, according to a Boston Children's Hospital research team led by David Ludwig, MD, PhD director, New Balance Foundation Obesity Prevention Center. These findings suggest that limiting these "high-glycemic index" foods could help obese individuals avoid overeating.

The study, published in the American Journal of Clinical Nutrition on June 26, 2013, investigates how food intake is regulated by dopamine-containing pleasure centers of the brain.

"Beyond reward and craving, this part of the brain is also linked to substance abuse and dependence, which raises the question as to whether certain foods might be addictive," says Ludwig.

To examine the link, researchers measured blood glucose levels and hunger, while also using functional magnetic resonance imaging (MRI) to observe brain activity during the crucial four-hour period after a meal, which influences eating behavior at the next meal. Evaluating patients in this time frame is one novel aspect of this study, whereas previous studies have evaluated patients with an MRI soon after eating.

Twelve overweight or obese men consumed test meals designed as milkshakes with the same calories, taste and sweetness. The two milkshakes were essentially the same; the only difference was that one contained rapidly digesting (high-glycemic index) carbohydrates and the other slowly digesting (low-glycemic index) carbohydrates.

After participants consumed the high-glycemic index milkshake, they experienced an initial surge in blood sugar levels, followed by sharp crash four hours later.

This decrease in blood glucose was associated with excessive hunger and intense activation of the nucleus accumbens, a critical brain region involved in addictive behaviors.

Prior studies of food addiction have compared patient reactions to drastically different types of foods, such as high-calorie cheesecake versus boiled vegetables.

Another novel aspect of this study is how a specific dietary factor that is distinct from calories or sweetness, could alter brain function and promote overeating.

"These findings suggest that limiting high-glycemic index carbohydrates like white bread and potatoes could help obese individuals reduce cravings and control the urge to overeat," says Ludwig.

Though the concept of food addiction remains provocative, the findings suggest that more interventional and observational studies be done. Additional research will hopefully inform clinicians about the subjective experience of food addiction, and how we can potentially treat these patients and regulate their weight.
