Police and firefighters at higher risk for mental disorders following traumatic events
Feb. 26, 2013 ? Police, firefighters and other protective services workers who are repeatedly exposed to traumatic events and are new to their profession are at greater risk of developing a psychiatric disorder, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers also found that protective services workers do not appear to have a higher prevalence of mental health problems than workers in other occupations.
The study results are featured in the February 2013 issue of Disaster Medicine and Public Health Preparedness.
"Our findings suggest that exposure to diverse types of traumatic events among protective services workers is a risk factor for new onset of psychopathology and alcohol use disorders," said Christopher N. Kaufmann, MHS, lead author of the study and a doctoral student in the Bloomberg School's Department of Mental Health. "When we examined the relationship of exposure to common traumas with the development of mood, anxiety and alcohol use disorders among protective services workers, we found that these workers were at greater risk for developing a mood or alcohol use disorder. Interestingly, this relationship was not seen in those who had been in these jobs for a longer period, but was strong and statistically significant in workers who recently joined the profession. Developing curricula in coping skills and providing timely interventions for early career protective services workers may help reduce future psychiatric morbidity in these workers."
Using data from the U.S National Epidemiologic Survey on Alcohol and Related Conditions researchers compared the prevalence of mental disorders of protective services workers to that of adults in other occupations. In addition, they examined the association of exposure to common traumatic experiences with the development of new mood, anxiety and alcohol use disorders among protective services workers who recently joined the workforce and those who had been in these jobs for a longer period. Lifetime and recent trauma events most commonly reported by protective services workers included: seeing someone badly injured or killed; unexpectedly seeing a dead body; having someone close die unexpectedly and having someone close experience a serious or life-threatening illness, accident or injury.
"The association between the number of different traumatic event types and incident mood and alcohol-use disorders, as well as post-traumatic stress disorder, was virtually confined to the group of early career protective services workers," said Ramin Mojtabai, MD, PhD, MPH, senior author of the study and an associate professor with the Bloomberg School's Department of Mental Health. "Future research should examine the coping skills of protective services workers who have been in these jobs for many years, which might make them less likely to develop psychiatric complications in the face of various potentially traumatic experiences."
The authors note, "Special support programs and services for these early career workers can potentially help to prevent development of chronic psychopathology and attrition from these critical jobs."

How To Make An Effective Website Design? ? Primediart Blog
There is one factor that is often overlooked in the field of website design. Web designers often overlook the functionality and the usability of the website. They focus on the design and in most cases develop a website that does not live up to its expectation. The success of the website depends on how user friendly it is. This is more important than the graphics as the visitor needs to find the information he/she is looking for on the internet. No matter how beautiful a website may look, if the visitor is not able to find the relevant information on the website he/she will never visit the website again.
All businesses who are looking for an online presence for increasing their brand awareness will always look for ways to enhance their business operations for growth and development. The development of a website always plays a vital role in these organizations and businesses should take note of the importance of navigation for its success.
When you are making a website for your business you should determine the needs of your user. The functionalities of the website will depend on them completely. There are some things your user will not need. This is why before you create a website it is very important for you to ascertain the needs of your existing and potential customers. This will help the designer insert functionalities to boost the appeal of the website with success. It is only when a website is user-friendly that it becomes profit oriented.
The website should be visually appealing to engage the attention of the visitor. The correct blend of graphics and text requires to be used. Posting the required and exact information in front will help the visitor get what he/she needs. If the website does not meet the expectations of the user, the visitor will close the window of the website or proceed back to where he/she began. This means you lose the visitor forever.
If you are looking for a good website with huge traffic you should take into account two things. The first is the credibility of the website and second is its quality. The internet is a huge marketplace and there are billions of sites. When it comes to credibility you will find there are only a few. A user will only keep coming back to a website that works. It is important for you to provide rich quality content along with the perfect combination of text and colors.
In conclusion, the website is the potent weapon that draws visitors. When you are looking for website designers ensure you bank on professional companies. They have skilled people and teams that understand your niche and target audience. This is why you must be smart enough to hire the right professionals for the job. In this way you get the best for your website. Your returns on investment also enhance and you get loyal customers coming back for fresh content about the nature of services and products you provide.

Were those the bones of Cleopatra's murdered sister?
Experts doubt that the 2,000-year-old bones, unearthed?in 1904 in what is now Turkey, belonged to?Arsinoe IV, Cleopatra's younger half-sister whom she ordered killed.?
The site of the Temple of Artemis in Ephesus, where Cleopatra had her sister Arsinoe murdered.

EnlargeA Viennese archaeologist lecturing in North Carolina this week claims to have identified the bones of Cleopatra's murdered sister or half-sister. But not everyone is convinced.

That's because the evidence linking the bones, discovered in an ancient Greek city, to?Cleopatra's sibling Arsinoe IV is largely circumstantial. A DNA test was attempted, said Hilke Thur, an archaeologist at the Austrian Academy of Sciences and a former director of excavations at the site where the bones were found. However, the 2,000-year-old bones had been moved and handled too many times to get uncontaminated results.
"It didn't bring the results we hoped to find," Thur?told the Charlotte News-Observer. She will lecture on her research March 1 at the North Carolina Museum of History in Raleigh.
The Ptolemy's bloody history
Arsinoe IV was Cleopatra's younger half-sister or sister, both of them fathered by Ptolemy XII Auletes, though whether they shared a mother is not clear. Ptolemic family politics were tough: When Ptolemy XII died, he made Cleopatra and her brother Ptolemy XIII joint rulers, but Ptolemy soon ousted Cleopatra. Julius Caesar took Cleopatra's side in the family fight for power, while Arsinoe joined the Egyptian army resisting Caesar and the Roman forces. [Cleopatra & Olympias: Top 12 Warrior Moms in History]
Rome won out, however, and Arsinoe was taken captive. She was allowed to live in exile in Ephesus, an ancient Greek city in what is now Turkey. However, Cleopatra saw her half-sister as a threat and had her murdered in 41 B.C.
Fast forward to 1904. That year, archaeologists began excavating a ruined structure in Ephesus known as the Octagon for its shape. In 1926, they revealed a burial chamber in the Octagon, holding the bones of a young woman.
Thur argues that the date of the tomb (sometime in the second half of the first century B.C.) and the illustrious within-city location of the grave, points to the occupant being Arsinoe IV herself. Thur also believes the octagonal shape may echo that of the great Lighthouse of Alexandria, one of the?Seven Wonders of the Ancient World. That would make the tomb an homage to Arsinoe's hometown, Egypt's ancient capital, Alexandria. ?
Controversial claim
The skull of the possible murdered princess disappeared in Germany during World War II, but Thur found the rest of the bones in two niches in the burial chamber in 1985. The remains have been debated every step of the way. Forensic analysis revealed them to belong to a girl of 15 or 16, which would make Arsinoe surprisingly young for someone who was supposed to have played a major leadership role in a war against Rome years before her death. Thur dismisses those criticisms.
"This academic questioning is normal," she told the News-Observer. "It happens. It's a kind of jealousy."
In 2009, a BBC documentary, "Cleopatra: Portrait of a Killer," trumpeted the claim that the bones are Arsinoe's. At the time, the most controversial findings centered on the body's lost skull. Measurements and photographs of the incomplete skull remain in historical records and were used to?reconstruct the dead woman's face.
From the reconstruction, Thur and her colleagues concluded that Arsinoe had an African mother (the Ptolemies were an ethnically Greek dynasty). That conclusion led to splashy headlines suggesting that Cleopatra, too, was African.
But classicists say the conclusions are shaky.
"We get this skull business and having Arsinoe's ethnicity actually being determined from a reconstructed skull based on measurements taken in the 1920s?" wrote David Meadows, a Canadian classicist and teacher, on his blog?rogueclassicism.
Not only that, but Cleopatra and Arsinoe may not have shared a mother.
"In that case, the ethnic argument goes largely out of the window," Cambridge classics professor Mary Beard wrote in the?Times Literary Supplement?in 2009.
Without more testing, the bones remain in identification limbo.
"One of my colleagues on the project told me two years ago there is currently no other method to really determine more," Thur told the News-Observer. "But he thinks there may be new methods developing. There is hope."

Cell scaffolding protein fascin-1 is hijacked by cancer
Tuesday, February 26, 2013
A protein involved in the internal cell scaffold is associated with increased risk of metastasis and mortality in a range of common cancers finds a meta-analysis published in Biomed Central's open access journal BMC Medicine.
The protein, fascin-1, is involved in bundling together the actin filaments which form the internal scaffolding of a cell and are involved in cell movement. Though it is absent, or only present at a low level in normal epithelial cells, several small studies have shown fascin-1 to be increased in many carcinomas, but its role in metastasis and mortality risk has been uncertain.
Researchers from the University of Bristol combined and reanalysed data from 26 studies looking at five different types of carcinomas. The meta-analysis showed that increased fascin-1 was associated with increased risk of mortality in breast, colorectal and oesophageal carcinomas but not in gastric or lung carcinoma. It was also associated with disease progression in breast and colorectal carcinoma, but not lung carcinoma. It was associated with local and distant metastasis in colorectal and gastric carcinomas but there was no involvement of fascin-1 in metastasis of oesophageal carcinomas.
These results show that the picture is not simple and that different types of cancer are affected in different ways. The story of fascin-1 not only provides a biomarker and potential avenue for research into anti-cancer therapy but also demonstrates the complexity of cancer.
Josephine Adams and Richard Martin who led this study said, "Our results show that fascin-1 is associated with several types of human carcinomas. The results will help focus further research into fascin-1 as a marker and potential target for cancer therapy to the most relevant types of carcinomas."

Billboard converts desert air into drinking water
An advertising agency has created what it is calling the world's first billboard that converts air into drinking water.
The billboard?a collaboration between agency Mayo DraftFCB and Peru's University of Engineering and Technology?was placed in Peru's rain-starved desert capital, Lima.
Lima gets less than an inch of rain per year on average, but since the city's humidity hovers around 98 percent, generators attached to the structure are able to capture atmospheric moisture, filter it and produce potable water.
The harvested water is then stored in 20-liter tanks and can be retrieved from taps at the base of the billboard.
"Agua aqui," a neon display near the base reads.
According to the university, the billboard produced 9,450 liters of drinking water in three months?enough to sustain hundreds of Peruvian families per month.
Watch a short video explaining the project below.
