3. Be Careful with Email Emails are a common source of spam and phishing scams. Avoid opening suspicious emails or clicking questionable links (within emails or without). Even if an email contains a link to a seemingly trustworthy site that you frequent (like your email provider or bank), it is always a good idea to avoid the link and point your browser to the site manually. This can avoid phishing scams. Additionally, simply loading the pictures in a spam message can send information back to its creator notifying them that your email address is an active target. So utilize your email’s spam filter to avoid infected emails from ever loading.

Blunders like these can be costly. And as burgeoning markets in Asia increase in importance, new insight is required to break through what you could call a language barrier.As a result of the globalization of business through mergers and international investment, English has become a lingua franca. Almost two billion people worldwide speak it, and more than half of these learned it as a second language. Moreover, global popular culture is dominated by English-language television, music, film, print and social media.

iStockPhoto (CBS) Can a person be truly addicted to the Internet? A new brain scan study shows not only can that be the case, but also that Internet addiction might cause the same brain changes that are seen in alcoholics and drug addicts. For the study, published in the Jan. 11 issue of PLoS One, researchers studied 17 men and women who were diagnosed with Internet addiction disorder (IAD) and compared scans of their brains to scans of 16 healthy people who weren't addicted to the web. Study participants were between the ages of 14 and 21 and lived in China. Video Game-Obsessed Mom Neglects Kids, Starves DogsAre social networking sites turning teens into substance abusers? The researchers found more patterns of  "abnormal white matter" on brain scans of Internet addicts, compared with scans of non-addicts. White matter areas in the brain contain nerve fibers that transmit signals to other parts of the brain. These changes showed evidence of disrupting pathways related to emotions, decision-making, and self control. The researchers said earlier studies have found similar white matter changes in the brain scans of people addicted to alcohol, cocaine, heroin, marijuana, meth, and ketamine (also known as "Special K"). "The results also suggest that IAD may share psychological and neural mechanisms with other types of substance addiction and impulse control disorders," the researchers wrote in the study. Professor Gunter Schumann, chair in biological psychiatry at the Institute of Psychiatry at King's College, London, told BBC News that he's come across similar findings in brain scans of video game addicts. "For the first time two studies show changes in the neuronal connections between brain areas as well as changes in brain function in people who are frequently using the Internet or video games," he said. Dr. Henrietta Bowden Jones, consultant psychiatrist at Imperial College in London, who runs the U.K.'s only clinic for Internet addicts, said hardcore gamers are more likely to be addicted to the Internet. "The majority of people we see with serious Internet addiction are gamers - people who spend long hours in roles in various games that cause them to disregard their obligations," Jones told The Independent. "I have seen people who stopped attending university lectures, failed their degrees or their marriages broke down because they were unable to emotionally connect with anything outside the game." According to the independent, an estimated 5 to 10 percent of Internet users are unable to control their usage and are considered addicts.

Dr. Kimberly Young has likened Internet addiction to addictive syndromes similar to impulse-control disorders on the Axis I Scale of the DSM. She also developed the Internet Addiction Diagnostic Questionnaire (IADQ) to diagnose the disorder. Meeting five of the following symptoms were considered necessary to be diagnosed.1. Do you feel preoccupied with the Internet (think about previous online activity or anticipate next online session)?2. Do you feel the need to use the Internet with increasing amounts of time in order to achieve satisfaction?3. Have you repeatedly made unsuccessful efforts to control, cut back, or stop Internet use?4. Do you feel restless, moody, depressed, or irritable when attempting to cut down or stop Internet use? 5. Do you stay online longer than originally intended?6. Have you jeopardized or risked the loss of significant relationship, job, educational or career opportunity because of the Internet?7. Have you lied to family members, therapist, or others to conceal the extent of involvement with the Internet?8. Do you use the Internet as a way of escaping from problems or of relieving a dysphoric mood (e.g., feelings of helplessness, guilt, anxiety, depression)?Other Symptoms Include:• Failed attempts to control behavior• Heightened sense of euphoria while involved in computer and Internet activities• Neglecting friends and family• Neglecting sleep to stay online• Being dishonest with others• Feeling guilty, ashamed, anxious, or depressed as a result of online behavior• Physical changes such as weight gain or loss, backaches, headaches, carpal tunnel syndrome • Withdrawing from other pleasurable activities

The key is to keep the other person in mind and go out of your way to be both polite and helpful — before you need help yourself, said Paul Gillin

The global digital divide is a special case of the digital divide, the focus is set on the fact that "Internet has developed unevenly throughout the world" [7] causing some countries to fall behind in technology, education, labor, democracy, and tourism. The concept of the digital divide was originally popularized in regard to the disparity in Internet access between rural and urban areas of the United States of America; the global digital divide mirrors this disparity on an international scale.

Richard Lavoie described the hidden curriculum as important social skills that everyone knows but no one is taught. This includes assumed rules, adult or student expectations, idioms, and metaphors. Understanding the hidden curriculum is difficult for everyone, but it is especially so when compounded with a deficit in social interactions.
