Student Question Word Cloud

After reading how Obama’s health care policy team created a word cloud indicating the most frequently used words and phrases in comments they received about health care, I decided to do the same with the questions I received from students via e-mail and Meebo chat this semester. The results can be seen at http://www2.bc.edu/~lissk/wordcloudf08.html . It’s more an impressionistic view of my electronic interactions with comm majors than it is anything useful, but I thought it would be fun to share.

Among my favorite bits: One of the largest words in the cloud – along with find, research, paper, topic, articles, and class – is “wondering.” I hadn’t realized how often students say “I was wondering…”

Then there’s this inadvertent but oh so logical progression from good to bad among the alphabetical list of words and phrases:

good .good articles. .good sources. .good thanksgiving. great .great depression. .hard time. .hard time finding.

Crunch Time: Research Help with Your Papers

The end of the semester, with paper and project deadlines approaching, is among the busiest time for students – and for me. I’m here to help with your research. Here are tips on different ways to get help.
  1. Set up a time to get together. In person consultations are not always necessary, but 10 or 15 minutes together are often all it takes to jump start your research or get you past a stumbling block. (We can take more time if it’s needed.) E-mail me or contact me via the live help boxes on many of my pages and we’ll find a time that works for both of us. You can also drop in, but I may be out or with another student.
  2. Ask a question online. Many questions can be answered without meeting in person. Send me an e-mail or use the live help boxes on my home page, course pages, and research guides. If I’m online, the live help box lets us chat without IM; if I’m not online, you can leave a message. (Just be sure to tell me who you are and how to get back to you.)
  3. Check out sources and tips on the pages I created for specific courses or for broad communication subject areas. There are links to all of them, and to key databases, on the Communication Research Help by Subject page on the library’s website.
Remember that I have many students coming for help at this time, so be patient if I’m not available at exactly the time that’s best for you. But do let me know if you need help, and I will work with you in whatever way I can.

Drill, Baby, Drill! Drilling Down in Search Results

How do you narrow down your results when a database search brings up too many hits to browse through? One way – available in more and more databases – is to drill down through the categories of hits listed alongside the results themselves.

These categories (sometimes referred to as facets, clusters, or result groups) can represent different subjects, types of publications, formats, dates, or other aspects of the items that came up when you entered your search terms.

Click on one of them and only those results from your original search that match that category will be shown. The categories can also help you identify other terms to search for, apart from your original terms.

Here are just a few of the databases in which you are able to drill down in this way: Communication & Mass Media Complete; LexisNexis Academic; Holmes One Search; Business Source Complete.

NBC News TV Broadcasts from 1968–Present Now Available Online

The BC Libraries’ subscription to Vanderbilt Television News Archive (VTNA) now includes streaming video from NBC News from August 5, 1968 to the present.


An arrangement between Vanderbilt and NBC earlier this year made it possible to add clips from NBC to those from CNN (1995-Present) already available to BC users of VTNA.


Available programs include the NBC Evening News, as well as extended television coverage of political conventions, elections, speeches, and major events such as the Watergate hearings, the Vietnam and Gulf Wars, the explosion of the shuttle Challenger, the 9/11 terrorist attacks, and more.


Use Advanced Search to limit your searches to NBC and/or CNN – news from other networks is indexed but does not include video – or look for the camera icon in the search results to indicate streaming video. ().


Vanderbilt Television News Archive is available online to BC faculty, students, and staff on or off campus. (Off–campus users will have to log in with their BC username and password.) Videos require the downloadable RealPlayer software for viewing.

Can You Say "BOO!" in APA Format?

Care to mix a little academic research with your trick-or-treating tonight?

As a Halloween treat -- and a break from the usual research tips -- here's a look at some of the ways scholars have looked at All Hallow's Eve. (All citations have been verified and most are available from the BC Libraries --
if you dare.)
  • "Reactions of zoo animals to 'disturbing' Halloween masks" (Master's Thesis, University of South Alabama, 2003)
  • "Influence of Valentine's Day and Halloween on birth timing" (Social Science and Medicine, 2011)
  • "Unmasking racism: Halloween costuming and engagement of the racial other" (Qualitative Sociology, 2007)
  • "Size of Halloween witch drawings prior to, on, and after Halloween" (Perceptual Motor Skills, February 1963)
  • "Assembling processes in a periodic gathering: Halloween in Athens, Ohio" (Sociological Focus, May 1992)
  • "The pink dragon is female: Halloween costumes and gender markers" (Psychology of Women Quarterly, June 2000)
  • "Jack O'Lanterns and integrating spheres: Halloween physics" (American Journal of Physics, June 2006)
  • "Dressing in costume and the use of alcohol, marijuana, and other drugs by college students" (Adolescence, Spring 1993)
  • "The Halloween Effect and Japanese equity prices: myth or exploitable anomaly?" (Asia-Pacific Financial Markets, December 2003)
So have a good time tonight, but be careful: there may be a scholar lurking behind that bush.

Meebo Me! Live Help Online

Do you sometimes wish you could get instant help when doing research online?

On many of my Web pages you’ll see a gray “Meebo” box labeled Ask for Help or Get Live Help. If I’m online, it will say “Ken Liss is online.” Type a message in the lower part of the box and hit enter, and I’ll respond.

It could be a quick question or a more complicated research problem. In either case, both ends of our live chat will appear in the upper box.

I’m not always available, but when I am I can answer many research questions this way. (If we need to meet in person we can arrange it right then and there.)

If the box says I’m offline, you can leave me a message without having to send an e-mail, and I’ll get it when I log back in. Just be sure to tell me who you are, how to reach you, and what you need help with. That way I can get back to you with an answer later.

Of course, you can always contact me the old-fashioned way – via e-mail, phone, or dropping by my office. But, whatever the method, don’t be afraid to ask for help.

Interpersonal Communication Research: Search Tips & Strategies

Are you starting research for a paper on relational or interpersonal communication? Here are some search tips & strategies from the Interpersonal Communication research guide.

Interpersonal communication takes many forms and occurs in many contexts. In beginning your research, plan out what aspects you are interested in.

For example, think about:
  • Context: communication at work, in school, on a sports team, at a party, at home, etc.
  • Type of relationship: friendship, family (spouse, sibling, parent-child), romantic relationship, etc.
  • Form of communication: speech, nonverbal, writing, phone, IM, etc.
  • Purpose of communication: persuasion, conflict resolution, support, information gathering, etc.
  • Other influences: race, age, gender, culture, etc.
Be as specific as possible in formulating your search terms, covering all aspects you're interested in, but be sure to use alternative/related terms as well.

Technical Problems with E-Journals

Technical problems are sporadically blocking our access to electronic journals. If you try to locate an article via FindIt or to look up an electronic journal via the E-Journal page or Quest, it may not work.

Our systems staff is hard at work trying to fix the problem, but if you are trying to find an article or journal and run into error messages, let me know. There may be some workarounds, and I will do my best to find them while the problem persists.

Holmes One Search

The BC Libraries have introduced a new way of searching the libraries’ collections of books, videos, DVDs, and other sources. It’s called Holmes One Search and it’s linked to from the Libraries home page. (You can also go there directly at http://www.bc.edu/holmes.)

Here are some of the advantages of searching the Libraries’ catalogs via Holmes:

  • Spell-checking your search terms (Did you mean….?)
  • Ranking search results by how well they match your search terms (relevance ranking)
  • Ability to narrow your results by topic, author, publication date, library, collection, language, and genre
  • Ability to save your results in your personal “e-shelf” or export records to RefWorks, your cell phone, or social networking sites. (You’ll have to sign in with your BC username and password to take advantage of these features.)

Holmes also lets you do quick searches of key communication databases (and those in other disciplines) though not as effectively as using the databases themselves.

Give it a try, and let me know if you have any questions, or send feedback to the BC Libraries via the Send Feedback link in Holmes.

Beyond Google: Key Communication Databases at BC

If you're not familiar with them already, you should get to know Communication Abstracts and Communication & Mass Media Complete (CMMC), two key tools for doing communication research at Boston College.

Communication Abstracts provides abstracts, or summaries, of scholarly communication articles going back to 1977. It does not provide the articles themselves, but the FindIt button that appears with every abstract can lead you to the full text of the article (in another database, in the library's print collection, or, via Interlibrary Loan, from another library).
Communication & Mass Media Complete (CMMC) indexes articles from academic journals as well as professional and trade magazines in the communication field. Complete articles are available in CMMC from approximately 200 of the 500 publications it covers. (FindIt links are available for others.)
These communication databases are by no means the only online resources for communication research. But they should definitely be on your radar as communication students.

A Note of Thanks

As the academic year comes to an end, I want to offer thanks to all of the students I've had an opportunity to work with on research questions, big and small, throughout the year. The topics you've come up with and the ways in which you've approached them have kept me on my toes and reinforced my sense of how interesting and diverse a discipline this is. I hope you've learned some tools and techniques for communication research -- and information gathering in general -- that you'll carry with you whether you're moving on or coming back for more. Congratulations to all of the graduates, and I'll see the rest of you in the fall.

24-Hour Study Space

Both the O’Neill Library Reserve Reading Room and Gargan Hall in the Bapst Library are open for 24-hour study through the night of Monday, May 12.

2008 Newspaper Ratings Report

Scarborough Research has released its 2008 report on audience penetration of newspapers in 161 U.S. metropolitan areas.

The Scarbourough Newspaper Audience Ratings Report 2008 provides data on 161 newspapers in 81 markets, including:
  • the number of adults in the market area (and percentage of the overall adult population) who have "read or looked into" the daily or Sunday edition of the newspaper within the past 5 weekdays or past Sunday;
  • the number and percentage of area adults who have visited the newspaper's website(s) in the past 7 days; and
  • the integrated audience -- the number and percentage of area adults who have read
    the printed newspaper or visited the newspaper’s website(s), or did both,
    during the past seven days.
The report is organized by Designated Market Area (a Nielsen category) and includes newspapers whose websites have at least 1% penetration in their market, as well as a Sunday print edition.

Do citation styles have you confused?

Are you putting together a list of works cited for a communication research paper and having trouble with citation formats?

There are several places you can turn for help:


* Online guides to APA and MLA from the Writers' Workshop at the University of Illinois at Urbana-Champaign.You'll find instructions and examples for the most common types of references and in-text citations -- and for some less common types, as well.


* The APA Style Guide to Electronic References (BC login required)



* Style manuals at the O'Neill Reference Desk. Ask for manuals on APA and MLA (as well as Chicago, Turabian, and others) at the desk. These are the official manuals and can help you figure out the right way to cite common and uncommon resources.

* APA Exposed: Everything You Ever Wanted to Know About APA Format but Were Afraid to Ask. Online tutorial prepared by a graduate student at the Harvard Graduate School of Education.

* RefWorks. If you're already using RefWorks, you probably know about the bibliography tool. If not, it might be a little late to learn everything about RefWorks, but get in touch with me and I can give you some tips on how to make the most of it in a short time.

Finally, don't be afraid to ask for help from me (in any of the usual ways) or from any of the librarians at the Reference Desk.

Crunch Time: Research Help with Your Papers

The last few weeks of the semester, with paper and project deadlines approaching, are among the busiest for students – and for me. I’m here to help with your research. Here are tips on different ways to get help.
  • * Set up a time to get together. In person consultations are not always necessary, but 10 or 15 minutes together are often all it takes to jump start your research or get you past a stumbling block. (We can take more time if it’s needed.)
  • * E-mail me or contact me via the live help boxes on many of my pages and we’ll find a time that works for both of us. You can also drop in, but I may be out or with another student.
  • * Ask a question online. Many questions can be answered without meeting in person. Send me an e-mail or use the live help boxes on my home page, course pages, and research guides. If I’m online, the live help box lets us chat without IM; if I’m not online, you can leave a message. (Just be sure to tell me who you are and how to get back to you.)
  • * Check out sources and tips on the pages I created for specific courses or for broad communication subject areas. There are links to all of them, and to key databases, on the Communication Research Help by Subject page on the library’s website.
Remember that I have many students coming for help at this time, so be patient if I’m not available at exactly the time that’s best for you. But do let me know if you need help, and I will work with you in whatever way I can.

Absolut Mexico

This story touches on so many issues of interest to communication studies -- advertising, intercultural communication, media and politics, crisis communication, and more -- that I just had to post it here.

Absolut Vodka has apologized for an ad that ran in Mexico with an old map showing the southwest United States as part of Mexico "In an Absolut World."

The ad, according to Fox News, provoked heated comments on Internet blogs and Web sites and a call for a boycott by U.S. consumers.

Here's what Absolut Vice President of Corporate Communications Paula Eriksson had to say on Absolut's own blog:

The In An Absolut World advertising campaign invites consumers to visualize a world that appeals to them -- one they feel may be more idealized or one that may be a bit "fantastic." As such, the campaign will elicit varying opinions and points of view. We have a variety of executions running in countries worldwide, and each is germane to that country and that population.

This particular ad, which ran in Mexico, was based upon historical perspectives and was created with a Mexican sensibility. In no way was this meant to offend or disparage, nor does it advocate an altering of borders, nor does it lend support to any anti-American sentiment, nor does it reflect immigration issues. Instead, it hearkens to a time which the population of Mexico may feel was more ideal.

As a global company, we recognize that people in different parts of the world may lend different perspectives or interpret our ads in a different way than was intended in that market. Obviously, this ad was run in Mexico, and not the US -- that ad might have been very different.

Her post has generated over 1500 comments since Friday. You can view the thread here. (Interestingly, Absolut requires you to fill in a birthdate to access their site.)

Finding Political News Online, the Young Pass It On

From today's New York Times:

"It is not news that young politically minded viewers are turning to alternative sources like YouTube, Facebook and late-night comedy shows like “The Daily Show.” But that is only the beginning of how they process information.


According to interviews and recent surveys, younger voters tend to be not just consumers of news and current events but conduits as well — sending out e-mailed links and videos to friends and their social networks. And in turn, they rely on friends and online connections for news to come to them. In essence, they are replacing the professional filter — reading The Washington Post, clicking on CNN.com — with a social one."

Super Bowl Ads: More Humor, More Animals, Fewer Celebrities

There was more -- though not necessarily better -- humor than ever before in this year's crop of Super Bowl ads, according to an updated interactive analysis on the New York Times Web site, but it was more likely to be delivered by animals than by celebrities.

85% of the ads featured humor, the highest percentage in the 25 years tracked on the Times site. At the same time, 43% of the ads featured animals, also a record. And, for the first time, there were more ads with animals than with celebrities. (32% featured celebrities, up from last year but below the record 40% in 2003.)

The Times analysis provides an interactive look at Super Bowl ads from 1984 to 2008. Use the slider at the top of the screen to move through the years. For each year, it shows a count of the number of ads in different product categories (vehicles, beverages, travel, food, etc.) plus the percentage of ads featuring humor, animals, and celebrities. Selected ads can be viewed on screen.

"If It Catches My Eye": Teens and Online News

Teenagers aren’t much into following serious news online, but news organizations can – and should – cultivate their interest, according to a new report from the Media Management Center at Northwestern University.

The report, "If It Catches My Eye: An Exploration of Online News Experiences of Teenagers," is based on a study of 65 Chicago-area teens conducted last year. Among its findings:
  • *Teens are not interested enough to go out of their way for "serious" news. So whatever news pops up in front of them when they turn on their computers – usually the large Internet portals and news aggregators – is what they see.
  • *At the same time, teens are "interestable." They will look at many different kinds of news online if it captures their attention – with subjects that interest them, video, pictures, the right topics, humorous and weird news and new things.
  • *News organizations should listen to teens and actively develop new products, campaigns and initiatives aimed at attracting teens to the news, “catching the eye" and then deepening their interest by focusing on subjects teens are most interested in, providing the features and functionalities they like, and building on their interest in humor.
  • *News content should be placed on sites where teens spend their time.
  • *Programs should be developed to decrease teens' angst about the news.
See the full report online for more.

"Video Snacking": Prime Time on the Web

"In cubicles across the country, lunchtime has become the new prime time," reports the New York Times, and content producers and advertisers are taking notice.

Office workers frequently spend at least part of their lunch hour watching short videos -- "video snacking" -- and while this midday spike is not new, according to the Times, the response of media companies is new.

The article describes how media organizations, including CNN, NBC, local television stations and newspapers, and others, are creating programming specifically targeted at the lunchtime Web crowd. Advertisers and marketers are paying attention too, with some reporting that "consumers are up to 30 percent more likely to make a purchase after viewing an advertisement at lunchtime than at other times of the day."
