Maximizing Results Through Internet Marketing
Internet marketing is essential for getting your business out there online. If you have not started using it, you definitely should. You will be able to know the basics of internet marketing, and you will be able to develop your own strategies after reading this guide.
Site wide links are links that are found on all of your website?s pages. Quite often, site-wide links are featured on the very bottom of a page?s design. If you have a page on your site that you would like everyone to view, you should implement site wide links. The site-wide links will be visible for them at the bottom of the page. It?s also possible to arrange links in a menu that provides a static way to navigate the entire site easily. An organized menu with descriptions for each link is most effective.
While your meta tags are not visible to your website visitors, they are very important for the search engine spiders because they help search engines find your website and determine the content. Your most important meta tags are the ones that you use first, and they should always be relevant to the content of your website. You will need to use meta tags strategically, but do not go overboard. Before placing any keywords, do research on which ones are popular now within your industry and choose those relevant to your target audience.

HTML tags give the text within a certain attribute (bold, italic, etc.). The more significant a certain piece of text is, the more likely it is that an experienced webmaster will put it in bold. Bold tagging is placed on titles that are meaningful and important within the text. Make sure your main title has the tag, and that you use sub-lines for each separate section of the text. If you do this, your website will be easier to understand, and search engine optimization will be increased. Using keywords in your titles helps identify what the important content of your webpage is.

Even though many webmasters use SEO and other marketing methods that are sure to work, you may also want to consider things like internet marketing. It is common for internet content, such as videos and websites, to go viral since the web is mostly driven by dedicated followers. This is basically word-of-mouth marketing on steroids. Word about the item spreads like wildfire across the internet. When content goes viral, it enjoys a brief, but intense surge of popularity, which can give your website traffic a great boost. If you develop unique and amusing content, you never know what good things could happen. You can also conduct research on things that have gone viral in the past, and try to identify what made those things so popular.
When it comes to internet marketing, these are just a couple of great beginner ideas to get you started. When you get the hang of it, you can add more ways to market your business online.

Supporters of Egypt?s Morsi march on military intelligence headquarters
Monday, 29 July 2013 06:24
'Supporters of Egypt?s ousted President Mohamed Morsi continue their march on the military intelligence headquarters in Cairo amid a looming state of emergency by the army.
Muslim Brotherhood spokesman Murad Ali said in the early hours of Monday that the demonstrators had set off from Rabia al-Adawiya Mosque in the north of the capital. The army warned the Morsi supporters ?not to come close to military facilities in general, and the headquarters of military intelligence specifically.?'

Judge: Fed chair Bernanke should be deposed in AIG bailout case
bernanke 
1 hour ago

Federal Reserve Board Chairman Ben Bernanke testifies before the Senate Banking, Housing and Urban Affairs Committee July 18, 2013 in Washington, DC.
Federal Reserve Chairman Ben Bernanke should testify in the lawsuit by American International Group Inc's former chief Maurice "Hank" Greenberg against the United States over the insurer's 2008 bailout, a judge ruled on Monday.
Judge Thomas Wheeler of the U.S. Court of Federal Claims rejected the government's effort to keep Bernanke from being deposed, saying the Fed chairman was a "central figure" in the decision to bail out AIG.
"Indeed, the court cannot fathom having to decide this multi-billion dollar claim without the testimony of such a key government decision maker," Wheeler wrote. "These facts constitute 'extraordinary circumstances' for the taking of Mr. Bernanke's deposition."
(Watch: Who will succeed Bernanke?)
Greenberg's Starr International Co, which once had a 12 percent stake in AIG, is suing over the government's taking of a 79.9 percent stake in the insurer in September 2008 and a separate 1-for-20 reverse stock split in June 2009.
Greenberg's attorney, Alanna Rutherford of Boies, Schiller & Flexner, said his team was pleased with the judge's decision.
Earlier this year Greenberg tried to force AIG to join his suit against the government over the $182.3 billion bailout, an effort the company ultimately rejected.
Greenberg is seeking tens of billions of dollars in compensation over the losses he incurred when the government rescued the company.
"Because of Mr. Bernanke's personal involvement in the decision-making process to bail out AIG, it is improbable that Plaintiff would be able to obtain the same testimony or evidence from other persons or sources," Wheeler wrote in his four-page order.
Wheeler said the court would extend "appropriate deference and courtesies" to Bernanke in scheduling the testimony; the judge also said he would attend the deposition himself.
It is tentatively scheduled for Aug. 16, the order noted.

Stunning 3D Rock Images Revealed in New Lab
PRINCETON, N.J. ? A geologist and an architect standing in a lab may sound like the start to a very nerdy joke, but a pair of these professionals have joined together to revolutionize the way scientists study structures, such as fossils, inside rocks.
Geologists use a variety of techniques to analyze fossils and other features trapped inside Earth's rocky layers. The most basic technique, dating back to the 19th century, involves slicing away layers of rock, taking pictures of each layer, and then recreating the full 3D shapes by connecting the dots between images. But this method is tedious and prone to human error.
"People have done this since Darwin," said Adam Maloof, a geoscientist at Princeton University who recently opened a rock imaging lab that brings this technique into the 21st century. "You can find very old articles from the 1870s where people sliced something five times, and then drew it, and put together a model of it."
Researchers have since devised more precise methods using electronic rock grinders and digital cameras, but, until now, the technique has not been automated.
Revolutionary redesign
Maloof has teamed up with architects at the Brooklyn-based Situ Studio to design a machine that automatically grinds layers as thin as 0.00025 centimeters ? thinner than a human hair ? and automatically takes high-resolution images along the way.
The grinding setup looks a bit like a mini car wash. On an automated steel shuttle, the rock first travels under misting nodules that clean away grime. Next, the rock passes back and forth under a 1-inch-thick (2.5 cm) diamond-studded grinding wheel, with a stream of water flowing to reduce dust. The sample then exits the grinder under a series of wiper blades and enters the limelight of an automated camera that snaps a shot from above. The shuttle then returns the rock to the start position, where the process repeats. [See photos of the lab and 3D rock models]
Maloof wears mist-covered safety goggles as he describes the special features of the room: Double-width cinder blocks in the walls help reduce sound pollution outside, and a climate control system maintains a constant room temperature.
"The main source of error with a grinder like this is the expansion and contraction of the steel," Maloof said, with the machine humming loudly behind him, and all of lights shut off except a beam glowing from the camera area. "If you have temperature fluctuations at night, for example, the steel will change size and there will be an error."
Even the slightest shift can cause images to misalign and jeopardize the precision of the digital model.
The machine hums along day and night, and can grind through several inches of rock within 24 hours. A modern manual setup would take up to two weeks to cover the same area, and would not be as accurate.
Ancient life
Maloof's interest in high-precision grinding was sparked in 2009 when he and his graduate students discovered what they thought could be the earliest evidence of fossilized animal life. In a 640-million-year-old rock formation in South Australia, the team found large patches of small red flakes that varied in size and shape, and looked nothing like the surrounding rock. The group brought samples back to Princeton, where they spent two weeks manually grinding and imaging about half an inch (1.5 cm) of sample. [Photos: The World's Most Famous Rocks]
With the help of Situ Studio, the group created a 3D model of their manual images and found what seemed to be remnants of ancient marine sponges. The team hopes to confirm this finding with their improved system.
"It definitely points to the potentials of interdisciplinary work," said Brad Samuels of Situ Studio, who helped Maloof choose the appropriate imaging and coding software, similar to what architects use to plan buildings. "The kinds of things that they needed in terms of tools and work flow are things that we have as a studio that we employ in designing spaces."
Oil drilling and meteorite dissection
A number of collaborators have already contacted Maloof about using the lab, including geologists in the oil industry wanting to analyze potential drilling rock, and geophysicists interested in dissecting meteorites.
"This is a very exciting instrument," said Roger Fu, a geophysics graduate student at MIT who will travel to the lab later this summer to study structures within meteorites that could help reveal information about how the solar system formed. "With the grinder, we should be able to get better 3D maps of meteorites than ever before."
A downside of the grinder is that it ultimately destroys the sample, Fu said. Some researchers avoid this by using X-ray scanning technology to peer inside rocks, but X-rays blur with depth, and do not differentiate between different materials of the same density.
The beauty of rocks
For now, Maloof is working out the final kinks of the system using less valuable samples. The results, so far, have produced stunningly beautiful images of structures inside rocks.
"If you looked at these with an X-ray, you would see absolutely nothing," Maloof said, pointing to an image of sand grains coated in concentric layers of calcium carbonate.
The compiled images of this rock reveals the full spherical form of each sand grain for the first time since they fused together hundreds of millions of years ago.
Editor's Note:?The author worked with Maloof's research group in 2010 and 2011 as a lab technician, and helped collect some of the fossil rocks from South Australia. She was not, however, involved in the analysis of the rock.

Report: Iran's outgoing president obtains clearance to set up high tech university
TEHRAN, Iran ? An Iranian news website says outgoing President Mahmoud Ahmadinejad has obtained clearance to establish a technology university in Tehran after he leaves office next week.
It's the first hint of what Ahmadinejad will do after he steps down on Aug. 4, when president-elect Hasan Rouhani is to be sworn in.
The conservative tasnimnews.com says Ahmadinejad received authorization from the country's Supreme Cultural Revolution Council to set up his university. The report was posted on the website Saturday.
It said the "Iranians University" will focus on information technology, nanotechnology, aerospace and nuclear science.
Ahmadinejad has fallen out with his one-time conservative allies and has been sidelined since Rouhani's June 14 election. But he still enjoys a significant political base, with loyalists especially concentrated in the poorer parts of the country.

Recession Hit Those With Mental Health Problems the Hardest ...
Reviewed by John M. Grohol, Psy.D. on July 27, 2013
Unemployment rates for people with mental health problems rose more than twice as much than for people without mental health problems during the recession, according to new research.
Researchers from King?s College London also found that this gap in employment rates was even greater for men and for those with low levels of education.
For the study, the researchers collected data in 27 European Union countries from more than 20,000 people in 2006 and again in 2010. Using the Eurobarometer survey, they assessed mental health, stigmatizing attitudes, socio-demographic information, such as age, gender, education level, and current employment rate.
At the start of the study, unemployment was at 7.1 percent for people without mental health problems, compared to 12.7 percent for people with mental health problems. In 2010, this rose to 9.8 percent and 18.2 percent, respectively.
This corresponds to an increase of 5.5 percent for people with mental health problems vs 2.7 percent for people without mental health problems.
?The economic recession has had enormous impact across much of Europe, but there is little information about the specific impact of the recession on groups who are already vulnerable to social exclusion, specifically, people with mental health problems,? said?Sara Evans-Lacko, Ph.D., lead author of the study from King?s College London?s Institute of Psychiatry.
?This is the first study to show that the European economic crisis has had a profound impact on people with mental health problems, compared to those without.?
The study also found that men and individuals with lower levels of education were significantly more likely to be unemployed after the recession. In 2010, 21.7 percent of men with mental health problems were unemployed, compared to 13.7 percent in 2006, the researchers report.
The researchers also found that stigmatizing attitudes ? especially beliefs regarding how dangerous people with mental health problems might be ? were an important factor contributing to the rise in unemployment.
Living in a country where a higher proportion of individuals believed that people with mental health problems were dangerous was associated with higher levels of unemployment for those people, according to the researchers.
The study also found that, in addition to higher unemployment, men with mental health problems and individuals with lower levels of education were less likely to seek help. They also had more negative attitudes to mental health, which may require specific forms of outreach, the researchers postulate.
?Our study emphasizes that one important implication of stigma and discrimination is exclusion from employment,? said Graham Thornicroft, Ph.D., co-author of the study.
?During periods of economic recession, attitudes to people with mental health problems may harden, further deepening social exclusion,? he said. ?Governments need to be aware of these risks, and employers need to be aware of their legal duty to comply with the Equality Act to support people with mental health problems coming into, and staying in, employment.?

50 Years On, Research On Sex Can Still Be A Lightning Rod
Virginia Johnson in 1997. She never graduated from college but became an authority on sexuality.
James A. Finley/APVirginia Johnson in 1997. She never graduated from college but became an authority on sexuality.
James A. Finley/APThe world has changed a lot since a divorced mother of two teamed up with a St. Louis gynecologist to study the physiology of sex.
Masters and Johnson's first book, Human Sexual Response, made Virginia Johnson and William Masters household names in the 1960s. More than any other scientists before them, they approached sex as a biological process to be observed, measured and analyzed.
Virginia Masters died this week at age 88. Her work is credited with dispelling many long-held myths about sex, from the thought that penis size matters to the notion that old people don't do it.
"We've gone through tremendous change," says Eli Coleman, director of the program in human sexuality at the University of Minnesota. He says he remembers when Masters and Johnson couldn't get their work published in medical journals. "That just isn't the case any more," Coleman told Shots. "Masters and Johnson were pioneers, and they legitimized the field. We're seeing the results of their courage and labor."
But research on sex can still be a tough sell, even in an age when Internet porn has made it possible for people to view every imaginable form of sexual conduct.
Research projects that have the word "sex" somewhere in them continue to run into trouble with critics in Congress and advocacy groups.
Johnson with her fellow researcher and sometimes husband, William Masters. The pair helped legitimize the study of human sexuality.
APThey include a project at the University of Minnesota funded by the National Institutes of Health that was designed to reduce the risk of HIV and other sexually transmitted diseases for homosexual men who looked for sexual partners on the Internet. The Traditional Values Coalition called that a "government-funded gay porn site."
"Did you know that your paycheck was hit in order to fund a study on how to use condoms correctly?" Fox News pundit Sean Hannity asked this spring. He was talking about a $423,500 study at the Indiana University's Kinsey Institute for Sex, Gender, and Reproduction on barriers to condom use. Hannity claimed the project, which got federal stimulus funding, failed to create jobs. The university says that in fact about nine researchers were employed for three years, and the research is studying how to increase proper condom use to reduce STDs and pregnancy.
"Sex is still a very volatile subject," says Jennifer Bass, director of communications for the Kinsey Institute. "The questions we had 50 years ago are different, but some of those questions still remain. Why do people do what they do even though they know about the consequences? Why do smart people get involved in dangerous situations? How does sex influence people's lives and choices?"
With the NIH research budget shrinking, scientists who study sex will find the hunt for funds no easier. "But I think there is a lot of support of basic science research in the area of sexuality," Coleman says ? at least from other scientists.
