Facebook and High Credit Card Debt

In internet on October 31, 2012 at 12:24

Interesting study.

I am not sure how accurate this is.

Story:

Does using Facebook cause you to spend money you don’t have and to pig out on junk food?

As far-fetched as that might sound, a pair of U.S. marketing professors say they have found a relationship between time spent on Facebook and lower credit scores, higher credit card debt and bigger waistlines. The authors say their work is the first study of its kind to link Facebook to personal financial habits.

The research is among a growing number of studies that are seeking to explain how the use of Facebook and other new technologies is shaping our lives, for better and worse, in areas as diverse as social and civic interactions, commerce and psychological well-being. This month, Facebook said it surpassed 1 billion active users worldwide. About half of U.S. adults say they use at least one social networking site — twice that of just four years ago.

Intense Facebook use goes with higher credit card debt

The researchers, Keith Wilcox of Columbia Business School and Andrew Stephen of the University of Pittsburgh’s business school, are not suggesting that people log onto Facebook and then, zombie-like, gorge themselves on debt and Twinkies. Instead, they say, the effects are subtle and cumulative.

The effects are most pronounced, they say, on Facebook users who have strong ties to their online friends. They say the process works like this: People browse through their social network of close friends. Participating in that supportive online community boosts their self-esteem. That brief increase in self-esteem reduces self-control.

Dangers Of Vaccines for Children,Cause Autism

Some of the Vaccines commonly used for Children, cause Autismin Children a recent Study reports.

If people know some basic details of Vaccine they would know that these dangers are always inherent.

Apart from the process of making Vaccine, there is guarantee  that the Vaccine would prevent the disease, not withstanding the tall claims.

vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body’s immune system to recognize the agent as foreign, destroy it, and “remember” it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

“Vaccines can be prophylactic (example: to prevent or ameliorate the effects of a future infection by any natural or “wild” pathogen), or therapeutic (e.g. vaccines against cancer are also being investigated; see cancer vaccine“).

(NaturalNews) If vaccines play absolutely no role in the development of childhood autism, a claim made by many medical authorities today, then why are some of the most popular vaccines commonly administered to children demonstrably causing autism in animal primates? This is the question many people are now asking after a recent study conducted by scientists at theUniversity of Pittsburgh(UP) in Pennsylvania revealed that many of the infant monkeys given standard doses of childhood vaccines as part of the new research developed autism symptoms.

For their analysis, Laura Hewitson and her colleagues at UP conducted the type of proper safety research on typical childhood vaccination schedules that the U.S.Centers for Disease Control and Prevention(CDC) should have conducted — but never has — for such regimens. And what this brave team discovered was groundbreaking, as it completely deconstructs the mainstream myth that vaccines are safe and pose no risk of autism.

Presented at theInternational Meeting for Autism Research(IMFAR) in London, England, the findings revealed that young macaque monkeys given the typical CDC-recommended vaccination schedule from the 1990s, and in appropriate doses for the monkeys’ sizes and ages, tended to develop autism symptoms. Their unvaccinated counterparts, on the other hand, developed no such symptoms, which points to a strong connection between vaccines and autism spectrum disorders.

Included in the mix were several vaccines containing the toxic additive Thimerosal, a mercury-based compound that has been phased out of some vaccines, but is still present in batch-size influenza vaccines and a few others. Also administered was the controversial measles, mumps, and rubella (MMR) vaccine, which has been linked time and time again to causing autism and various other serious, and often irreversible, health problems in children (http://www.greenhealthwatch.com)

“This research underscores the critical need for more investigation into immunizations, mercury, and the alterations seen in autistic children,” said Lyn Redwood, director ofSafeMinds, a public safety group working to expose the truth about vaccines and autism. “SafeMinds calls for large scale, unbiased studies that look at autism medical conditions and the effects of vaccines given as a regimen.”

Vaccine oversight needs to be taken from CDC and given to independent agency, says vaccine safety advocate

Adding to the sentiment, Theresa Wrangham, president ofSafeMindscalled out the CDC for failing to require proper safety studies of its recommended vaccination schedules. Unlike all other drugs, which must at least undergo a basic round of safety testing prior to approval and recommendation, vaccinations and vaccine schedules in particular do not have to be proven safe or effective before hitting the market.

“The full implications of this primate study await publication of the research in a scientific journal,” said Wrangham. “But we can say that it demonstrates how the CDC evaded their responsibility to investigate vaccine safety questions. Vaccine safety oversight should be removed from the CDC and given to an independent agency.”

Research or propaganda?
A recent study [1] which found no evidence of a link between MMR and autism was widely trumpeted by the media. It compared 1,294 children diagnosed with autism or other pervasive development disorders (PDDs) between 1987 and 2001 in England and Wales with 4,469 children of the same sex and similar age who were registered with the same general practices but did not have a recorded diagnosis of autism. Around 80% of both the autism and non-autism groups had received an MMR jab.

The validity of this MMR vaccination study has been challenged. It was based on the UK General Practitioner Research Database (diagnostic reports from GPs), whose validity as a basis for epidemiological research has been widely criticised. It stands accused in particular of massively under-reporting diseases like autism. These are often diagnosed by educational specialists rather than GPs so, inevitably, are not included in the GP database.

None of these studies differentiated between autism in general and the ‘regressive autism’ highlighted by Dr Wakefield and others, where a child whose neurological development appears to be normal starts to regress (about 10% of autism cases). Several questions need to be answered:

  • Why are researchers not differentiating between autism in general autism and ‘regressive autism’?
  • The 2002 Danish study researchers must have known that the Danish Health Service only diagnosed autism at five years old plus. Why did they limit their study to children under five?
  • Why has the UK and US media given the Danish study re-run so little coverage?

and going back in MMR history …

  • Why was the 1992 mass MMR programme in the UK followed a year later by a sudden rise in autism levels?
  • Why were further mass MMR campaigns in late 1994 and in 1996 both followed by sudden and steep rises in autism figures a year later?

Can there any longer be doubt that the medical establishment wants to obscure any possible link between ‘regressive autism’ and the MMR jab?

Oscillating gels could find many uses.Video.

In Science on March 25, 2011 at 12:44

Self-oscillating gels are materials that continuously change back and forth between different states — such as color or size — without provocation from external stimuli. These changes are caused by the Belousov-Zhabotinsky chemical reaction, which was discovered during the 1950s. Without stirring or other outside influence, wave patterns from this chemical reaction can develop within the material or cause the entire gel itself to pulsate.

Irene Chou Chen, a doctoral candidate in the lab of Krystyn J. Van Vliet, the Paul M. Cook Career Development Associate Professor of Materials Science and Engineering, has been studying exactly how adjusting the size and shape of these gels can affect their behavior.

By integrating experiments with computer simulations conducted by collaborators Olga Kuksenok, Victor Yashin and Anna C. Balazs at the University of Pittsburgh, the MIT researchers have shown that pattern formation within the material can be controlled by changing the gel’s size or shape. When the reaction is restricted to a sub-millimeter-sized gel, the material exhibits chemical oscillations that cause it to mechanically swell and shrink. Lasting for several hours, these self-sustained oscillations exemplify chemomechanical coupling — where chemical reactions cause mechanical changes. The work will be published in the March issue of the journal Soft Matter as part of a special focus on “active soft matter.”

The self-sustained pulsations could enable unique applications for this material, the researchers say, such as using it as an environmental sensor or as an actuator that could react to specific conditions. The simulations developed by the University of Pittsburgh group could also help to make such applications easier to implement.
