Slideshow: A Visual Guide to Erectile Dysfunction
What Is Erectile Dysfunction (ED)?
Erectile dysfunction (ED) occurs when a man has repeated problems sustaining an erection. Without treatment, ED can make sexual intercourse difficult. The condition, sometimes called impotence, affects an estimated 15 million to 30 million men in the U.S. While the topic was once taboo, awareness has skyrocketed with recent advances in treatment for ED.

Survey Shows Teenage Girls Don’t Always Present Themselves Honestly in Social Networking
Reviewed by Laura J. Martin, MD
Nov. 11, 2010 -- When it comes to the Internet, teenage girls, particularly those with low self-esteem, don’t always present themselves honestly.
Girl Scouts of the USA conducted a national survey in June 2010 of 1,026 girls ages 14 through 17. The survey found that girls often downplay their positive characteristics on social media networking sites, and many choose to portray themselves as sexy or crazy.
Seventy-four percent of those surveyed said they believe their peers use social networking web sites to make themselves sound “cooler than they really are” and 41% said they use the Internet to portray themselves in a way that was different from the reality.
Overall, Girl Scouts of the USA found pluses and minuses for teenage girls using online social networking -- from getting involved in a cause to being bullied.
Among the survey findings:
- 82% reported themselves as smart
- 76% reported themselves as kind
- 59% said they were a good influence
- 84% said they were fun
- 33% of girls with low self-esteem said their online image didn’t match their in-person image compared with 18% of girls with higher self-esteem
- 22% of girls with low self-esteem portrayed themselves as sexy compared with 14% of those with a higher self-esteem
- 35% of girls with low self-esteem identified themselves as crazy online compared with 28% of girls with a higher self-esteem
- 30% of girls said online social networking increased the quality of their friendships and 52% said they got involved in a cause they care about through online social networking
- 85% said they talked to their parents about safe online social networking behavior
Fifty percent reported not always being as careful as they should be about what they say and do on social networking sites. Sixty-eight percent said they have had a negative experience online, such as being bullied.
Social Networking and Emotional Well-Being
About 40% of girls also reported being worried about getting into trouble with their parents or teachers, missing a job opportunity, not getting into college of their choice, or having someone lose respect for them because of their online social activities.
Ninety-two percent of survey respondents said they would give up online social networking if it meant keeping their best friend, someone to interact with in person. Just over half of those surveyed reported having online friends they had never met in person.
Girl Scouts of the USA said the findings shed light on how teenage girls use online social networking and how their emotional well-being could be affected.
“Adults and teens alike need greater understanding about the ways girls represent themselves and communicate on social networking sites,” Kimberlee Salmond, senior researcher at the Girl Scout Research Institute, says in a news release. “If girls are portraying themselves differently online than they are in person, this can impact their identity, sense of self and relationships.”

Practicing Source-ery
Sidney Silverman Library at Bergen Community College (NJ) offers a straightforward definition of the difference between primary and secondary sources. "Primary sources are original materials such as autobiographies, poems, diaries, documents, research articles, original data, or an original creation such as a piece of art." Materials that "describe, explain or interpret primary sources," they explain, are secondary sources. "These include literature criticism, biographies, books about a topic, reviews, encyclopedias and dictionaries."
In Primary vs. Secondary, they also provide this useful checklist of examples:
| Primary Sources | Secondary Sources |
| autobiography | biography |
| painting or object of art | article reviewing or criticizing the art |
| personal diary or letters | book about the person or event |
| treaty (government document) | essay interpreting the document |
| poem, novel, short story, etc. | literary criticism of the work |
| firsthand observer accounts of event | report on event years later |
| play, film, television show, performance | biography of the writer |
| speech given by a person | commentary on the speech |
| research report by researchers | interpretation of the research |
| photographs | explanation of photographs |
Primary Sources Online
| Primary Sources Online "Tens of thousands of archival collections can be found on the web," says Leslie F. Stebbins. "These digitized primary resources provide researchers with unprecedented access to collections that previously were only available in one location and kept behind locked doors." Also available online, notes the author of Student Guide to Research in the Digital Age: How to Locate and Evaluate Information Sources (Westport, CT: Libraries Unlimited, 2006), 68. are "information (which) indicates what is owned by a particular archive and…search aids that give a detailed inventory of the holdings of a particular collection and other descriptive information." In Find Digitized Primary Source Collections on the Web, Stebbins guides researchers to some larger online digital library collections, archival search engines and "tools that point to digitized and print collections," and information on collections available outside the U.S. And "If you have some flexibility with the topic you are working on," the author suggests, "you might want to try one of the larger collections such as the American Memory Project. Locate an interesting collection and work backward to the development of your topic." |
