    Social networking sites and our lives

    Questions have been raised about the social impact of widespread use of social networking sites (SNS) like Facebook, LinkedIn, MySpace, and Twitter. Do these technologies isolate people and truncate their relationships? Or are there benefits associated with being connected to others in this way? The Pew Research Center’s Internet & American Life Project decided to examine SNS in a survey that explored people’s overall social networks and how use of these technologies is related to trust, tolerance, social support, and community and political engagement.

    The findings presented here paint a rich and complex picture of the role that digital technology plays in people’s social worlds. Wherever possible, we seek to disentangle whether people’s varying social behaviors and attitudes are related to the different ways they use social networking sites, or to other relevant demographic characteristics, such as age, gender and social class.

    The number of those using social networking sites has nearly doubled since 2008 and the population of SNS users has gotten older.
    In this Pew Internet sample, 79% of American adults said they used the internet and nearly half of adults (47%), or 59% of internet users, say they use at least one of SNS. This is close to double the 26% of adults (34% of internet users) who used a SNS in 2008. Among other things, this means the average age of adult-SNS users has shifted from 33 in 2008 to 38 in 2010. Over half of all adult SNS users are now over the age of 35. Some 56% of SNS users now are female.

    Facebook dominates the SNS space in this survey: 92% of SNS users are on Facebook; 29% use MySpace, 18% used LinkedIn and 13% use Twitter.

    There is considerable variance in the way people use various social networking sites: 52% of Facebook users and 33% of Twitter users engage with the platform daily, while only 7% of MySpace and 6% of LinkedIn users do the same.

    On Facebook on an average day:

    15% of Facebook users update their own status.
    22% comment on another’s post or status.
    20% comment on another user’s photos.
    26% “Like” another user’s content.
    10% send another user a private message
    Facebook users are more trusting than others.

    We asked people if they felt “that most people can be trusted.” When we used regression analysis to control for demographic factors, we found that the typical internet user is more than twice as likely as others to feel that people can be trusted. Further, we found that Facebook users are even more likely to be trusting. We used regression analysis to control for other factors and found that a Facebook user who uses the site multiple times per day is 43% more likely than other internet users and more than three times as likely as non-internet users to feel that most people can be trusted.

    Facebook users have more close relationships.
    The average American has just over two discussion confidants (2.16) – that is, people with whom they discuss important matters. This is a modest, but significantly larger number than the average of 1.93 core ties reported when we asked this same question in 2008. Controlling for other factors we found that someone who uses Facebook several times per day averages 9% more close, core ties in their overall social network compared with other internet users.

    Facebook users get more social support than other people.
    We looked at how much total support, emotional support, companionship, and instrumental aid adults receive. On a scale of 100, the average American scored 75/100 on a scale of total support, 75/100 on emotional support (such as receiving advice), 76/100 in companionship (such as having people to spend time with), and 75/100 in instrumental aid (such as having someone to help if they are sick in bed).

    Internet users in general score 3 points higher in total support, 6 points higher in companionship, and 4 points higher in instrumental support. A Facebook user who uses the site multiple times per day tends to score an additional 5 points higher in total support, 5 points higher in emotional support, and 5 points higher in companionship, than internet users of similar demographic characteristics. For Facebook users, the additional boost is equivalent to about half the total support that the average American receives as a result of being married or cohabitating with a partner.

    Facebook users are much more politically engaged than most people.
    Our survey was conducted over the November 2010 elections. At that time, 10% of Americans reported that they had attended a political rally, 23% reported that they had tried to convince someone to vote for a specific candidate, and 66% reported that they had or intended to vote. Internet users in general were over twice as likely to attend a political meeting, 78% more likely to try and influence someone’s vote, and 53% more likely to have voted or intended to vote. Compared with other internet users, and users of other SNS platforms, a Facebook user who uses the site multiple times per day was an additional two and half times more likely to attend a political rally or meeting, 57% more likely to persuade someone on their vote, and an additional 43% more likely to have said they would vote.

    Facebook revives “dormant” relationships.
    In our sample, the average Facebook user has 229 Facebook friends. They reported that their friends list contains:

    22% people from high school
    12% extended family
    10% coworkers
    9% college friends
    8% immediate family
    7% people from voluntary groups
    2% neighbors
    Over 31% of Facebook friends cannot be classified into these categories. However, only 7% of Facebook friends are people users have never met in person, and only 3% are people who have met only one time. The remainder is friends-of-friends and social ties that are not currently active relationships, but “dormant” ties that may, at some point in time, become an important source of information.

    Social networking sites are increasingly used to keep up with close social ties.
    Looking only at those people that SNS users report as their core discussion confidants, 40% of users have friended all of their closest confidants. This is a substantial increase from the 29% of users who reported in our 2008 survey that they had friended all of their core confidants.

    MySpace users are more likely to be open to opposing points of view.
    We measured “perspective taking,” or the ability of people to consider multiple points of view. There is no evidence that SNS users, including those who use Facebook, are any more likely than others to cocoon themselves in social networks of like-minded and similar people, as some have feared.

    Moreover, regression analysis found that those who use MySpace have significantly higher levels of perspective taking. The average adult scored 64/100 on a scale of perspective taking, using regression analysis to control for demographic factors, a MySpace user who uses the site a half dozen times per month tends to score about 8 points higher on the scale.

    Frequency of eating

    The best way to prevent tooth decay is to limit the frequency of eating. It is not possible to clean the teeth fast enough, frequently enough, and thoroughly enough to overcome every acid attack we experience after every bite of food.
    Furthermore, not only can sweets cause decay; but all carbohydrates can promote decay! Especially any that stick to teeth such as pretzels or crackers.

    Hope everyone has a safe, cavity free holiday and remembers these tips while feasting!

    Bisphenol A, the endocrine-disrupting chemical used in containers, appeared to inhibit and disrupt meiosis in human eggs in vitro.

    Bisphenol A, the endocrine-disrupting chemical used in the manufacture of many kinds of food containers, appeared to inhibit and disrupt meiosis in human eggs in vitro.
    BPA has been found in human follicular fluid, and its meiosis-disrupting effect on eggs is supported by animal studies, according to research presented October 17 at the annual meeting of the American Society for Reproductive Medicine in Orlando, Florida.

    Dr. Linda Giudice, a reproductive endocrinologist at the University of California, San Francisco who was not involved in the study, told Reuters Health that the type of disruption seen in the study could lead to chromosomal abnormalities.

    Mouth Wash Recalled

    Colgate-Palmolive has recalled its Periogard 0.2% chlorhexidine mouthwash as a precaution, owing to possible bacterial contamination. The bacteria concerned, Burkholderia, are unlikely to cause harm to healthy people but may cause infection in those with a compromised immune system or with a chronic lung condition such as cystic fibrosis.

    Fluoride debate….is it beneficial in our water?

    ADA’s Fluoridation Facts Short Answer
    Fluoride, at the concentrations found optimally fluoridated water, is not toxic according to generally accepted scientific knowledge.

    ADA’s Fluoridation Facts Long Answer
    Like many common substances essential to life and good health — salt, iron, vitamins A and D, chlorine, oxygen and even water itself — fluoride can be toxic in excessive quantities. Fluoride in the much lower concentrations (0.7 to 1.2 ppm) used in water fluoridation is not harmful or toxic.

    Acute fluoride toxicity occurring from the ingestion of optimally fluoridated water is impossible.104 The amount of fluoride necessary to cause death for a human adult (155 pound man) has been estimated to be 5-10 grams of sodium fluoride, ingested at one time.140 This is more than 10,000-20,000 times as much fluoride as is consumed at one time in a single 8-ounce glass of optimally fluoridated water.

    Chronic fluoride toxicity may develop after 10 or more years of exposure to very high levels of fluoride, levels not associated with fluoride intake in drinking optimally fluoridated water. The primary functional adverse effect associated with long term excess fluoride intake is skeletal fluorosis. The development of skeletal fluorosis and its severity is directly related to the level and duration of fluoride exposure. For example, the ingestion of water naturally fluoridated at approximately 5 ppm for 10 years or more is needed to produce clinical signs of osteosclerosis, a mild form of skeletal fluorosis, in the general population. In areas naturally fluoridated at 5 ppm, daily fluoride intake of 10 mg/day would not be uncommon.74 A survey of X-rays from 170,000 people in Texas and Oklahoma whose drinking water had naturally occurring fluoride levels of 4 to 8 ppm revealed only 23 cases of osteosclerosis and no cases of skeletal fluorosis.141 Evidence of advanced skeletal fluorosis, or crippling skeletal fluorosis, “was not seen in communities in the United States where water supplies contained up to 20 ppm (natural levels of fluoride).”74, 121 In these communities, daily fluoride intake of 20mg/day would not be uncommon.74 Crippling skeletal fluorosis is extremely rare in the United States and is not associated with optimally fluoridated water; only 5 cases have been confirmed during the last 35 years.74

    Additional discussion on this topic may be found in Question 16 and Question 32.

    The possibility of adverse health effects from continuous low level consumption of fluoride over long periods has been extensively studied. As with other nutrients, fluoride is safe and effective when used and consumed properly. No charge against the benefits and safety of fluoridation has ever been substantiated by generally accepted scientific knowledge. After 50 years of research and practical experience, the preponderance of scientific evidence indicates that fluoridation of community water supplies is both safe and effective.98

    At one time, high concentrations of fluoride compounds were used in insecticides and rodenticides.27 Today fluoride compounds are rarely used in pesticides because more effective compounds have been developed.104 While large doses of fluoride may be toxic, it is important to recognize the difference in the effect of a massive dose of an extremely high level of fluoride versus the recommended amount of fluoride found in optimally fluoridated water. The implication that fluorides in large doses and in trace amounts have the same effect is completely unfounded. Many substances in widespread use are very beneficial in small amounts, but may be harmful in large doses – such as salt, chlorine and even water itself.

    Repeat of Question 21.
    Is fluoride, as provided by community water fluoridation, a toxic substance?

    Opposition’s Response

    Yes. “It is now clear that fluoride is a potentially harmful substance when present in the water supply in any amount. Those who want their children to have fluoride can give it individually, in measured doses, and more safely, reliably and cheaply than when put in the water. We can see no justifiable reason why everyone in the city should be needlessly subjected to any degree of life-long risk such as is created when a known poison is added to the water. We can accept no compromise with the established principle that the city’s water supply must be kept as safe as possible for everyone.” (Dr. Simon Beisler, Chief of Urology, Roosevelt Hospital, New York City, Dr. Fred Squier Dunn, Head of Oral Surgery Department, Lenox Hill Hospital, NYC, Dr. John Garlock, Consulting Surgeon, Mount Sinai Hospital, NYC, Dr. Edgar A. Lawrence, Director of Medicine at Lenox Hill Hospital, NYC. and Dr. Girard F. Oberrender, Director of Otalaryngology at Lenox Hill Hospital, NYC.)

    “It is well documented in the scientific literature that the substance sodium fluoride (used in fluoridation) has an effect on the metabolic cycle, from which we get the energy to maintain the life process and repairs to the body. The amount of the dosage has very little to do with the question because it is a ‘cumulative material’ — that is, it collects in the body — its effect would vary from person to person.” (Professor J. Earle Galloway, Drake University, Bio-Chemist and Chairman, Dept. of Pharmacology, Des Moines, IA.)

    Dr. L. O. Maynard, Cornell University, authority on the role of minerals in nutrition, states: “There is no proof that fluoride is a dietary essential.”

    “Fluorine has never been proved to be an indispensable chemical element for the maintenance of healthy body and healthy teeth. There is no disagreement about the fact that fluorine is a protoplasmic and enzymatic poison.” (Dr. V. O. Hurme, former director of Clinical Research, Forsyth Dental Infirmary for Children, Boston, MA.)
