What 'Negative Temperature' Really Means

On Friday we discussed news of researchers getting a quantum gas to go below absolute zero. There was confusion about exactly what that meant, and several commenters pointed out that negative temperatures have been achieved before. Now, Rutgers physics grad student Aatish Bhatia has written a comprehensible post for the layman about how negative temperatures work, and why they're not actually "colder" than absolute zero. Quoting:
"...you first need to engineer a system that has an upper limit to its energy. This is a very rare thing ? normal, everyday stuff that we interact with has kinetic energy of motion, and there is no upper bound to how much kinetic energy it can have. Systems with an upper bound in energy don?t want to be in that highest energy state. ...these systems have low entropy in (i.e. low probability of being in) their high energy state. You have to experimentally ?trick? the system into getting here. This was first done in an ingenious experiment by Purcell and Pound in 1951, where they managed to trick the spins of nuclei in a crystal of Lithium Fluoride into entering just such an unlikely high energy state. In that experiment, they maintained a negative temperature for a few minutes. Since then, negative temperatures have been realized in many experiments, and most recently established in a completely different realm, of ultracold atoms of a quantum gas trapped in a laser."

Our refinance loan just fell through because the appraisal came in ...

This after jumping thru all their hoops, gathering data etc. and making the house perfect for the appraisal. Now lender won't even give us the report unless we pay $400 for a report that does us no good, or telling us to pay $100 for the appraisers mileage and getting nothing, not even a verbal appraisal amount. Lender is a total jerk on the phone to me,. Has an attitude when talking to me, versus my husband.

Cervical back pain is a kind of pain which concerns our neck and can cause great damage to it if proper treatment is not given to the patient. In order to give our head the much needed support, there are seven vertebrae which together form the cervical spine. Our neck can easily get damaged or injured as it holds 8 nerve roots in total and is also susceptible to strains and this can cause great pain to a person in such a situation.

The Clone Wars: Asking Geopolitical Questions to Pre-Teens ...

[Enjoy this guest post from frequent contributor Timothy Swann! - Ed.]

?There are pockets of rebels on many of these planets that just need guidance. With training and resources, they could attack soft targets??

?Now, to be clear, we are not here to fight your war; rather, to show you how to conduct it in the most efficient and successful way possible.?

?I think of it as an insurgency to help realign these planets with the Republic.?

The world is a difficult place. We?re surrounded by war, suffering and revolution ? and the news is rightly filled with discussion of the rightness or wrongness of our own nations? involvement in such affairs. Sometimes we want to get away from it all. Many of us, it seems, do it by diving into cartoons whose technical demographic is far younger than our own ? the successes of Friendship Is Magic, Adventure Time and The Clone Wars all speak to this.

Trouble is, the Clone Wars isn?t really a kids show.

We?ve heard before on the site here that The Clone Wars is tragedy dressed up as heroic legend and that it lionises the clones and their morally questionable Jedi generals, but the evocation of the Iliad and the bioethics of a clone army don?t usually speak to day-to-day political issues. The current series of The Clone Wars, on the other hand, does just that.

The Clone Wars Season Five, subtitled Army of Revenge, quickly dispenses with the silliness of Darth Maul and his brother Savage Oppress to move on to its first multi-part storyline, which concerns the Republic handwringing (they may use unethical clonetroopers, but they think about it all the time) over whether they ought to intervene in a civil war on the planet Onderon. Onderon is a planet with a history of violent internal conflict, as well as leadership that can only be described as categorically evil. The last time the Republic got involved in the internal matters of Onderon, it led to a galactic war. The Republic decided, considering how many civil wars there are that fall along Separatist versus Republic lines, to use Onderon as a trial case. Send the Jedi to equip, resource and train the pro-Republic forces and have them overthrow the relatively legitimate government of Onderon without direct attacks on the Separatist-backed Onderonian government led by King Sanjay Rash.

In other words, whether NATO should have intervened in Libya.

cw-royalty

Firstly, the Republic was using this as a test case ? many were wary of getting involved, but there were many opportunities for the Republic to replicate this if it proved succesful. As it stands, the impact of the Arab Spring remains strong in many nations ? it has provoked uprisings and civil wars. The USA or NATO or the UN, which each here roughly align with the Republic ? a force for democracy that isn?t always a shining example of doing it well or effectively ? have not intervened except in one case, that of Libya. But the idea that those groups might do the same in Syria is certainly not off the table, though the idea that it might be achieved with limited involvement seems increasingly unlikely. Thus far, NATO has only gone as far as trying to limit the civil war?s impact on Turkey, one of its oldest member states. Greater intervention in Yemen may yet occur to act against Al-Qaeda, dependent on the new unity government?s success at that mission.

The Onderonian Resistance was based around loyalty to the ousted King of Onderon, Ramsis Dendup, the deposed and imprisoned king. He, however, has no operational or indeed direct input to the rebels, but merely serves as their inspiration. The royalist flag of the Libyan rebels similarly evokes King Idris I, who was deposed, exiled and sentenced to death by Gaddafi. Idris I was pro-UN and pro-British but did not get involved in the Cold War, just as Dendup supported the Republic but did not involve himself in the Clone Wars. Equally, Gadaffi supported the Soviet Union, but also, like Rash, maintained a great deal of personal independence.

The key military objective for the rebels was retaking the occupied city of Iziz, which is the capital of Onderon. This battle takes time ? the city was filled with a superior military force and the population are terrified. In Tripoli, an initial uprising in February 2011 was put down more successfully than elsewhere, and the layout of the city and shutdown of the internet made it a key Gaddafi stronghold that held until the rebels could bring well-trained and well-equipped forces into play. The Onderonian rebels had the advantage of anti-droid weaponry which would not harm civilians, but the battle was not truly accomplished until they broadcast propaganda holographically and the impotent brutality of the King was revealed. As the rebels approached Tripoli, on the 20th August, an uprising began within the city, aiding the rebels in taking it.

Focusing on specialist weaponry, the Onderonian rebels were skilled at guerrilla tactics and urban warfare, but proved immensely vulnerable to Separatist HMP Gunships, lacking any means of gaining air superiority. The Republic, admittedly via Black Market sources, provided the rebels with rocket launchers that allowed them to wipe out the gunships and redress this balance. Efforts of a different sort but with the same aim were taken by NATO in establishing a no-fly-zone. As far as I am aware, no fighters were engaged in this operation, but air defences were destroyed, and the aircraft also targeted ground and naval vehicles to defend civilians and rebel forces that they themselves could not expect to counter.

Fear will keep them in line!

Fear will keep them in line!

Returning to taking the city ? one of the reasons why the rebels entered Tripoli so swiftly was that a Loyalist commander surrendered one of his guard battalions to repay the murder of his cousin by the regime years before. The moral quandary for the head of the Onderonian Militia is more complex ? General Tandin wants to preserve the peace and livelihood of the people of Onderon, but in the end it is personal reasons that causes him to move from supporting King Rash to King Dendup ? that he will not see the former King executed in front of the people. From this point on, Rash is hamstrung, relying only on outside forces that cannot be trusted.

The leader of the Onderonian Resistance is unclear at first, but emerges by popular assent to be Steela Gerrera ahead of her more militant brother Saw and the more peaceful former Senator Lux Bonteri.

However, the conflict ends with the death of this leader in fighting the air power of the state ? a gunship shot down by the rebels crashes, leaving both Steela and the rightful King in mortal peril. The Jedi Ahsoka Tano attempts to save them both, retrieving the King, but another gunship wounds her and she releases Steela from her telekinetic grip to fall to her death. Similarly chaotic events led to the death of one of the key leaders of the Libyan rebels ? Abdul Fatah Younis was the Commander-in-Chief of the rebel military, having formerly been the Minister of the Interior for the Gaddafi government. Whilst coming back from Benghazi where he had discussed with the rebel leadership his family?s ties with the regime, though those who summoned him may not have had the authority to do so, his car was attacked. He was shot dead during the attack. One of two offshoots of the main NTC rebels are believed to have been involved ? both seeking revenge for his actions as Minister of the Interior. He was, nevertheless, buried as a hero of the rebellion.

So long as we don't turn the country over to religious fanatics ...

So long as we don?t turn the country over to religious fanatics ?

Each civil war is ended by the death of the dictator. In the case of Libya, Gaddafi was found and either killed in crossfire or summarily executed by the rebel forces. This was after a satellite phone call he made was intercepted by NATO, who sent air forces to disable his convoy and allow the rebels to capture him. By contrast King Rash was killed by the Separatist droid general sent to lead the Separatist units at the forefront of the civil war, apparently because of his uselessness to the Separatist cause having failed to crush the rebels.

To conclude, there seem to be a good number of parallels, which might be considered surprising for the genre and target audience of the show. But the Star Wars Expanded universe always has this in it somewhere. The Yuuzhan Vong spoke to the fears in the War On Terror of an ideological battle against something supposedly more alien than Communism. Legacy of the Force shows how moves to create safety reduce freedom. Fate of the Jedi references the Arab Spring continually.

Equally, the original Star Wars films were designed as a specific political fantasy: George Lucas said in 1973 (as quoted in The Making of Star Wars) that:

?The Empire is like America ten years from now, after Nixonian gangsters assassinated the Emperor and were elevated to power in a rigged election; created civil disorder by instigating race riots, aiding rebel groups, and allowing the crime rate to rise to the point where a ?total control? police state was welcomed by the people. Then the people were exploited with high taxes, utility, and transport costs. Gangsters, a cartel made up of power companies, transport companies & crime organizations. Other companies had to pay bribes to stay in business.?

More recently, when asked about the parallels of Revenge of the Sith and George W. Bush (in the audio commentary to Revenge of the Sith), he stated:

?When I first started making the film [the first Star Wars], it was during the Vietnam War, and it was during a period when Nixon was going for a third term ? or trying to get the Constitution changed to could go for a third term ? and it got me to thinking about how democracies turn into dictatorships. Not how they?re taken over where there?s a coup or anything like that, but how the democracy turns itself over to a tyrant.?

So, be aware the next time you turn on Cartoon Network (or as it will soon no doubt be, Disney XD), you might just be getting involved in an unlikely geopolitical analogy, without even so much as a Gadaffi Stick joke.

What Is Risk Management and Why Do We Need It? | Getting Money ...

Every business is prone to risk is everyday operations. Risks can be analyzed through scenario analysis, which involves the study of possible future happenings. The approach places risk into three probabilities; the probability of the occurrence, the probable loop holes and the probable impact.

What Is Risk Management and Why Do We Need It?

Risk management is the act of identifying the potential risks and developing strategies to decrease their chances or eliminating them altogether. Here?s a list of the possible risks that a business can face.

1. Health and safety

There are health and safety risks for all businesses. For example, a customer or an employee can slip on a wet floor. An employee with an infected disease can prevent harm to the co-workers, and an overtime shift of employees can lead to headaches. Therefore, risk management is important for every type of business.

2. Financial risks

Financial risks are mostly faced by financial institutions. According to J.P Morgan, one of the major reasons of sub-prime mortgage crises was poor risk management. Small and large companies are at a risk of client confidence, bankruptcy and dissolution of the business. These financial risks can be avoided through a sound strategy.

3. Legal risks

Legal risks are present for any business, and they can expose the business to big financial penalties. Arthur Andersen, the accountancy firm, lost the trust of its clients and investors due to the Enron debacle. Many partners and employees also resigned.

Businesses may be overwhelmed as all risks are a priority. So how does a business owner manage all the risks taking into consideration the budgetary constraints? The idle solution lies in enterprise risk management, which is a holistic risk management solution. Professional risk management strategies are also available for businesses such as LexisNexis risk management. All risk management solutions and strategies include these 3 processes.

1. Identification and assessment of risks

After taking the service of a professional company, the senior authorities have to agree to the process. It?s importance to identify those risks for the organization that are talked about but not documented. Identification will require carrying out different processes and activities such as holding workshops and meetings among employees and management. This will allow for the input of those who may have documented variety of risks.

2. Creating a strategy

After the risk has been identified, a strategy is going to be required. Enterprise diversification strategy requires creating backups in perfect correlation. Risks will also be prioritized depending on the extent of harm they can cause during strategic planning.

3. Regular reviews

Risk management needs to be a long term process with frequent reviews of the strategy designed to reduce or eliminate the risks. Through regular reviews, the risk management company and business can find out whether the strategy needs to be revised or not. It?s also important for businesses to consider it as a part or the overall planning and decision-making.

Risk management can have a positive effect on the overall image of the company. It also improves the decision-making process and leads to the efficient use of resources, leading to higher revenue in the long run.

Pronunciation of 's' sounds impacts perception of gender, researcher finds

Jan. 4, 2013 ? A person's style of speech -- not just the pitch of his or her voice -- may help determine whether the listener perceives the speaker to be male or female, according to a University of Colorado Boulder researcher who studied transgender people transitioning from female to male.

The way people pronounce their "s" sounds and the amount of resonance they use when speaking contributes to the perception of gender, according to Lal Zimman, whose findings are based on research he completed while earning his doctoral degree from CU-Boulder's linguistics department.

Zimman, who graduated in August, is presenting his research Jan. 5 at the annual meeting of the Linguistic Society of America in Boston.

"In the past, gender differences in the voice have been understood, primarily, as a biological difference," Zimman said. "I really wanted to look at the potential for other factors, other than how testosterone lowers the voice, to affect how a person's voice is perceived."

As part of the process of transitioning from female to male, participants in Zimman's study were treated with the hormone testosterone, which causes a number of physical changes including the lowering of a person's voice. Zimman was interested in whether the style of a person's speech had any impact on how low a voice needed to drop before it was perceived as male.

What he found was that a voice could have a higher pitch and still be perceived as male if the speaker pronounced "s" sounds in a lower frequency, which is achieved by moving the tongue farther away from the teeth.

"A high-frequency 's' has long been stereotypically associated with women's speech, as well as gay men's speech, yet there is no biological correlate to this association," said CU-Boulder linguistics and anthropology Associate Professor Kira Hall, who served as Zimman's doctoral adviser. "The project illustrates the socio-biological complexity of pitch: the designation of a voice as more masculine or more feminine is importantly influenced by other ideologically charged speech traits that are socially, not biologically, driven."

Vocal resonance also affected the perception of gender in Zimman's study. A deeper resonance -- which can be thought of as a voice that seems to be emanating from the chest instead of from the head -- is the result of both biology and practice. Resonance is lower for people whose larynx is deeper in their throats, but people learn to manipulate the position of their larynx when they're young, with male children pulling their larynxes down a little bit and female children pushing them up, Zimman said.

For his study, Zimman recorded the voices of 15 transgender men, all of whom live in the San Francisco Bay area. To determine the frequency of the "s" sounds each participant made, Zimman used software developed by fellow linguists. Then, to see how the "s" sounds affected perception, Zimman digitally manipulated the recording of each participant's voice, sliding the pitch from higher to lower, and asked a group of 10 listeners to identify the gender of the speaker. Using the recordings, Zimman was able to pinpoint how low each individual's voice had to drop before the majority of the group perceived the speaker to be male.

Zimman's work was funded in large part by the Wenner-Gren Foundation and is now being reviewed for publication.

Gunmen in Pakistan shoot dead seven aid workers near capital

PESHAWAR, Pakistan (Reuters) - Gunmen ambushed and shot dead six Pakistani women aid workers and a male doctor on Tuesday, police said, and the charity they worked for said it suspected the attacks were linked to recent murders of polio vaccination workers.

Their vehicle was raked with gunfire as they returned home from work at a children's community center run by Pakistani charity Ujala, or Light, said district police officer Abdur Rashid Khan. Their driver was seriously wounded in the attack.

The shooting in Swabi district, about 75 km (45 miles) northwest of the capital of Islamabad, was the first attack on aid workers in the area.

The victims worked at the center for aid agency Support With Working Solutions, whose head Javed Akhtar said they had told their other 160 staff to suspend work following the killings.

The organization is involved in health education in underdeveloped parts of the country, Akhtar said. It had run a school and dispensary in Swabi and helped vaccinate children against polio, a disease that can cripple or kill within hours of infection.

He suspected the shootings might be linked to a string of attacks on polio vaccinators last month.

"This seemed to be part of the campaign against the polio drive by certain anti-polio elements," he said.

Two weeks ago, gunmen killed nine health workers taking part in a national polio vaccination drive in a series of attacks. Most of the victims were young women earning about $2 a day.

The Taliban said they did not carry out those attacks although its leaders have repeatedly denounced the vaccination program as a plot to sterilize people or spy on Muslims.

Aid workers have frequently been kidnapped or killed in Pakistan, a nuclear-armed nation of 180 million that is struggling to contain a Taliban insurgency and plagued by endemic corruption and violent crime.
