Relationship troubles? Some sad music might help you feel better

Wednesday, May 15, 2013

Consumers experiencing relationship problems are more likely to prefer aesthetic experiences that reflect their negative mood, according to a new study in the Journal of Consumer Research.

"Emotional experiences of aesthetic products are important to our happiness and well-being. Music, movies, paintings, or novels that are compatible with our current mood and feelings, akin to an empathic friend, are more appreciated when we experience broken or failing relationships," write authors Chan Jean Lee (KAIST Business School), Eduardo B. Andrade (FGV School of Administration), and Stephen E. Palmer (University of California, Berkeley).

Consumers experience serious emotional distress when intimate relationships are broken, and look for a surrogate to replace the lost personal bond. Prior research has reported that consumers in a negative mood prefer pleasant, positive aesthetic experiences (cheerful music; fun comedies) to counter their negative feelings. However, under certain circumstances, consumers in negative moods might choose aesthetic experiences consistent with their mood (sad music; tear-jerking dramas) even when more pleasant alternatives are also available.

In one study, consumers were presented with various frustrating situations and asked to rate angry music relative to joyful or relaxing music. Consumers liked angry music more when they were frustrated by interpersonal violations (being interrupted; someone always being late) than by impersonal hassles (no internet connection; natural disaster).

In another study, consumers were asked to recall experiences involving loss. Preference for sad music was significantly higher when they had experienced an interpersonal loss (losing a personal relationship) versus an impersonal loss (losing a competition).

"Interpersonal relationships influence consumer preference for aesthetic experiences. Consumers seek and experience emotional companionship with music, films, novels, and the fine arts as a substitute for lost and troubled relationships," the authors conclude.

ITHACA, N.Y. - Clam fossils from the middle Devonian era some 380 million years ago now yield a better paleontological picture of the capacity of ecosystems to remain stable in the face of environmental change, according to research published today (May 15) in the online journal PLOS ONE.

Trained to examine species abundance the head counts of specimens paleontologists test the stability of Earth's past ecosystems. The research shows that factors such as predation and organism body size from epochs-gone-by can now be considered in such detective work.

Back 380 million years ago, New York was under the Devonian sea. Today, the fossils found in the rocks of this region have become well known for documenting long-term stability in species composition that is, the same species have been found to persist with little change over a 5 million year period. But research has found that species abundance in this ancient ecosystem went up and down, generating debate among paleontologists whether the fauna, as a whole, was also stable in terms of its ecology.

A team of Cornell, Paleontological Research Institution (PRI) an affiliate of Cornell University and University of Cincinnati researchers revisited this debate by examining the ecological stability of the Devonian clam fauna.

"To understand how these species fared in the Devonian, you have to look at how they interacted with other species. There is more to ecology than just the abundance and distribution of species," said Gregory Dietl, Cornell adjunct professor, earth and atmospheric sciences, and a paleontologist at PRI.

The research, "Abundance Is Not Enough: The Need for Multiple Lines of Evidence in Testing for Ecological Stability in the Fossil Record," was written by Judith Nagel-Myers, paleontologist, PRI; John Handley, PRI; Carlton Brett, University of Cincinnati professor of geology; and Dietl.

The scientists took a new approach to testing ecological stability: In addition to counting numbers of clams, they examined repair scars on fossil clams that were left by the unsuccessful attacks from shell-crushing predators, and the body size of the clam assemblage as it yields biological information on the structure of food webs.

"Surprisingly, predation pressure and the body size structure of the clams remained stable, even as abundance varied," said Nagel-Myers. Possible mechanisms that explain the clam assemblage's stability are related to the dynamics of food webs the same mechanisms operating in food webs today. In one mechanism, predators switched between feeding on different clam species as their abundance varied.

The ancient Devonian ecosystem was more complex than previously thought, as it cautions scientists against basing conclusions on a single factor. Said Dietl: "Our results thus raise serious doubt as to whether ecological stability can be tested meaningfully, solely based upon the abundance of taxa, which has been the standard metric used to test for ecological stability in paleoecology."

Jeffrey Sinclair Sex Case: Gens. Dan Allyn, Jeffrey Colt Ordered To Testify

FORT BRAGG, N.C. ? A military judge on Tuesday ordered two U.S. Army generals to testify about whether they were pressured by superiors to charge another general with the sexual assault of a female captain.

The judge, Col. James Pohl, granted a pre-trial motion from lawyers representing accused Brig. Gen. Jeffrey Sinclair. It compels testimony by Gen. Dan Allyn and Maj. Gen. Jeffrey Colt.

Sinclair's legal team alleges that high-ranking Pentagon officials may have placed improper pressure on Allyn, then the commander of the 18th Airborne Corps at Fort Bragg and Sinclair's boss.

A court martial for Sinclair is scheduled to begin June 25 on charges that include forcible sodomy, indecent acts, violating orders and adultery.

Allyn, who was recently promoted to head the Army's Forces Command, could testify as soon as Wednesday. It is not clear when Colt, the current commander at Fort Bragg in North Carolina, might take the stand.

In court Tuesday, Sinclair's lawyers cited e-mails obtained over the weekend that they contend suggest top Army generals might have been consulted ahead of Allyn's referral of the charges last year. Under the military code of justice, a commanding officer weighing whether to charge a subordinate with a crime is supposed to be insulated from the influence of those farther up the chain of command.

Richard Scheff, Sinclair's lead civilian lawyer, told the judge that Allyn, Colt and other Army officials had declined requests to speak to the defense team voluntarily and asked that they be subpoenaed.

"I've got e-mails that suggest the involvement of senior officials in this case," Scheff said. "This is not a fishing expedition."

Sinclair's case is heading to trial amid the sting of sexual assault allegations and embarrassing sex scandals involving the military. President Barack Obama publicly warned the Defense Department earlier this month that he expects its leaders to take tougher action against sexual predators and redouble efforts to prevent assaults within the ranks.

A 27-year Army veteran, Sinclair faces life in prison if convicted on the sexual assault charge. It's rare for an Army general to face court-martial. There have been only two cases in recent years.

Pohl agreed Tuesday to a request from prosecutors to dismiss one of the more minor charges against Sinclair, that he violated an order by possessing alcohol while on deployment in Afghanistan. An unopened bottle of scotch was found in his quarters ? a gift defense lawyers said came from a top Pentagon official visiting the Muslim nation.

Sinclair was deputy commander in charge of logistics and support for the 82nd Airborne Division in Afghanistan before being relieved in May 2012 during the criminal investigation. He has been on special assignment since then at Fort Bragg.

The female captain at the heart of the case said she carried on a three-year sexual relationship with Sinclair, a married father of two who was her direct superior. Adultery is a crime under military law, and the admission could end her career.

She testified at the evidentiary hearing last year that she repeatedly tried to break off the affair, but that Sinclair threatened to kill her and her family if she told anyone about their frequent sexual liaisons in hotels, headquarters and war zones.

The woman said she usually wanted to have sex with the general, though she said that on two occasions after they had argued he exposed himself and physically forced her to perform oral sex, even as she sobbed.

The Associated Press does not publicly identify victims of alleged sexual assaults.

Two other female officers who served with Sinclair also testified that they had given the general nude photos at his request.

Analysis: Syria's savagery will thwart reconciliation

By Oliver Holmes

BEIRUT (Reuters) - Syrian soldiers slowly stab a man to death, puncturing his back dozens of times. A rebel commander bites an organ ripped out of an enemy combatant. A young boy hacks the head off a prisoner. A soldier mutilates the genitals of a corpse.

These are the images of Syrian conflict, the first war in which the prevalence of camera phones and Internet access has allowed hundreds of gruesome war crimes to be broadcast, spreading hatred and fear. They are defining the war that is spilling across Syria's borders and making reconciliation an ever more distant prospect.

Brutality has been used as a tool since the revolt began two years ago, when videos emerged of government soldiers torturing pro-democracy protesters. In response to the crackdown, the opposition took up arms and now fighters from both sides are filming themselves committing atrocities.

Ghoulish footage of violence is not filmed surreptitiously, but with pride by the assailants who often speak to camera.

Rebel commander Abu Sakkar, known to journalists and revered by many rebels, was shown in a video on Sunday cutting organs out of a dead soldier, addressing the camera as he ripped the flesh: "I swear to God we will eat your hearts and your livers," he warned President Bashar al-Assad's forces as his men cheered.

Sakkar was a founding member of the Farouq Brigade, one of the main rebel units in Syria, but has since formed his own battalion as the opposition fragments. In the mosaic of hundreds of opposition groups, Sakkar's men are seen as neither secular nor hardline Islamists, but as some of the hardiest fighters.

Another picture posted online shows a rebel holding the severed head of a man, supposedly an Assad loyalist, over a barbecue as if to cook it. The fighter smiles and poses confidently, gripping a tuft of hair.

ZERO SUM GAME

Reinoud Leenders, an associate professor in the war studies department of King's College London, says that these brutal displays are used as a tool of war by both sides.

"It's the ultimate expression of disrespect and dehumanizing your opponent," he said.

In the face of an insurgency, he says, Assad's forces have used mass killings and torture to root out rebel fighters hiding among civilians.

"The regime has difficulty in pinning down opposition members, so they scare civilians from the area to get the rebels exposed. It looks irrational and emotional but there are rational reasons," he said.

Nadim Houry, a Syria and Lebanon researcher for Human Rights Watch, has documented abuses since the start of the revolt and says that he is seeing more and more brutal acts.

"Both parties are acting like they are facing an existential threat," he said. The opposition and the government see the war as a zero sum game, both fighting for survival, he says.

This fear of defeat silences condemnation from supporters of both sides, he says. The main Syrian opposition group condemned the video of a rebel commander taking a bite from the dead soldier but many opposition supporters dismissed the brutality.

On some opposition Facebook pages people celebrated the act. Others berated the media for highlighting one particular event, saying they should focus on indiscriminate killing of men, women and children by Assad's war planes and militia.

The Syrian government has never acknowledged brutality in army ranks, instead referring to people killed by soldiers as "terrorists" and areas captured by its forces as "cleansed".

Syria's war started as a popular uprising against the Assad dynasty, which has ruled for over four decades using secret police, intimidation and brute force.

But majority Sunni Muslims lead the revolt, while Assad gets his core support from his Alawite sect, an offshoot of Shi'ite Islam, leading to sectarian fighting and hatred.

International powers have taken sides, with the West and Gulf countries supporting the opposition, while Iran and Russia back Assad. While war crimes are condemned in words, there has been no real deterrent for the perpetrators, which Houry said has allowed atrocities to continue.

"What is particularly troubling is the silence of the international powers," Houry said. He referred to a recent army and loyalist militia attack in the coastal town of Banias in which at least 62 people, including babies, were killed.

"We have been seeing (these massacres) for over a year. What is shocking is the level of indifference. People shrug their shoulders and look away," said Houry.

Since Syria never signed up to the treaty establishing the International Criminal Court, the court could only investigate allegations of brutality there with a referral from the United Nations Security Council - something permanent members Russia and China have so far blocked.

RECONCILIATION

The United States and Russia have proposed a peace conference to try to end the war, but savagery from both sides means that the unlikely event of a peace agreement might not stop atrocities and fighting between increasingly disparate militias.

"The ideas of reconciliation are now unrealistic. The conflict is as much about the conflict itself than pro- or anti-regime," Leenders said. "I see a total mismatch between the US and Russian narrative and what is going on in Syria."

In its sectarian nature and big power inertia, the Syrian conflict has drawn comparisons with Bosnia, which was torn apart by Serbs, Croats and Muslims in a 1992-95 war that gave the world the term ?ethnic cleansing' and was marked by some of the worst atrocities in Europe since World War Two.

Almost 17 years since that war ended, the wounds are still raw. Bodies are still being dug up and a cycle of blame and denial weighs on efforts to reconcile communities. Bitterness runs deep and spills into politics, stifling development.

Details of the worst atrocities are coming to light even now. Each side clings to its own narrative of the war.

In March, an ethnic Montenegrin man was jailed for 45 years for killing 31 people and raping at least 13, including a pregnant woman in front of her young child.

The judge in the case said the defendant, Veselin Vlahovic, nicknamed Batko, sometimes forced his victims to kiss his hand as he beat them, and once ordered a man to have sex with the corpse of a woman whose throat had been cut.

In Srebrenica, 8,000 Muslim men and boys were gunned down in five summer days in 1995, their bodies bulldozed into pits, buried and reburied in a bid to conceal the crime. Many Serbs still dispute the figures, despite mountains of testimony at the United Nations war crimes tribunal in The Hague.

The strength of feeling on all sides has made political compromise in the name of peace difficult, at times impossible, and acts as a brake on development.

In Lebanon, which lies next to Syria and fought its own 15-year civil war which ended in 1990, fault lines between religions remain strong and armed militias still come to blows as a weak government looks on helplessly.

Many Lebanese fighters accused of war crimes are now politicians as people support powerful members of their sect to safeguard against the influence of their foes.

"We don't have real reconciliation in Lebanon right now. Reconciliation requires justice," said rights researcher Houry, who lives in Beirut. "There is a tear at the fabric of Syria, similar to what we saw in Lebanon."

Computer scientist publishes new algorithm cluster to data mine health records

Wednesday, May 15, 2013

The time may be fast approaching for researchers to take better advantage of the vast amount of valuable patient information available from U.S. electronic health records. Lian Duan, an NJIT computer scientist with an expertise in data mining, has done just that with the recent publication of "Adverse Drug Effect Detection," IEEE Journal of Biomedical and Health Informatics (March, 2013).

The article spotlights a new and promising way of using a combination of commonly used existing algorithms to root out more information about adverse drug reactions within electronic health records available to the researchers. The new pattern, which when compared against the most commonly used existing sole algorithm, showed an almost 25 percent improvement in outcome. Although the idea could theoretically be applied beyond electronic health records, this paper focuses only on using them to find adverse medical reactions to a drug therapy.

"Large collections of electronic patient records have long provided abundant, but under-explored information on the real-world use of medicines. But when used properly these records can provide longitudinal observational data which is perfect for data mining," Duan said. "Although such records are maintained for patient administration, they could provide a broad range of clinical information for data analysis. A growing interest has been drug safety."

In this paper, the researchers proposed two novel algorithms?a likelihood ratio model and a Bayesian network model?for adverse drug effect discovery. Although the performance of these two algorithms is comparable to the state-of-the-art algorithm, Bayesian confidence propagation neural network, by combining three works, the researchers say one can get better, more diverse results.

Since the actual adverse drug effects on a given dataset cannot be absolutely determined, the researchers made use of a simulated observational medical outcomes partnership dataset. They constructed this "dataset" with the predefined adverse drug effects to evaluate their methods.

Experimental results show the usefulness of the proposed pattern discovery method on the simulated dataset by improving the standard baseline algorithm?chi-square?by 23.83 percent.

Duan, whose innovative research on large-scale data mining has applications in the business world as well as many industries, including marketing, social networking and bioinformatics. Whereas most data mining experts search for correlation pairs, he focuses on correlated sets of arbitrary size. His research focuses on correlation search, community detection, and density-based clustering and outlier detection.

Duan holds two doctorates-- one in computer science from the Chinese Academy of Sciences, China, and the other in information systems with an emphasis on data mining from the University of Iowa.
