College students don’t know how to use Google

Posted on by

I recently heard about this study at a faculty development day: college students have difficulty understanding and using search results.

Researchers with the Ethnographic Research in Illinois Academic Libraries project watched 30 students at Illinois Wesleyan University try to search for different topics online and found that only seven of them were able to conduct “what a librarian might consider a reasonably well-executed search.”

The students “appeared to lack even some of the most basic information literacy skills that we assumed they would have mastered in high school,” Lynda Duke and Andrew Asher write in a book on the project coming out this fall.

At all five Illinois universities, students reported feeling “anxious” and confused when trying to research. Many felt overwhelmed by the volume of results their searches would turn up, not realizing that there are ways to narrow those searches and get more tailored results. Others would abandon their research topics when they couldn’t find enough sources, unaware that they were using the wrong search terms or database for their topics.

The researchers found that students did not know “how to build a search to narrow or expand results, how to use subject headings, and how various search engines (including Google) organize and display results.” That means that some students didn’t understand how to search only for news articles, or only for scholarly articles. Most only know how to punch in keywords and hope for the best.

Such trust in technology. Wonder where this came from?

I like how anthropologists were involved in this study. Including an observation component could make this data quite unique. I don’t think many people would think that ethnographic methods could be used to examine such up-to-date technology.

Several other thoughts:

1. How many adults could explain how Google displays pages?

1a. If people knew how Google organized things, would they go elsewhere for information?

2. Finding and sorting through information is a key problem of our age. The problem is not a lack of information or possible sources; rather, there is too much.

3. Who exactly in schools should be responsible for teaching this? Librarians, perhaps, but students have limited contact. Preferably, all teachers/professors should know something about this and talk about it. Parents could also impart this information at home.

4. I’m now tempted to ask students to include all of their search terms in final projects so that I can check and see whether they actually sorted through articles or they simply picked the top few results.

More on examining six degrees of separation on Facebook

Posted on by

I noted earlier this week that Yahoo and Facebook are conducting an experiment to see how interconnected people are the world are. Here are some more information about the experiment that was revealed in an interview with Yahoo sociologist/research scientist Duncan Watts:

  • On the quality of Facebook’s data:

Cameron Marlow, Facebook’s research scientist and “in-house sociologist,” said that because Facebook’s social graph is essentially the best representation of real world relationships available, “our data can speak more definitively to this question than anything else in history.

Facebook has a treasure trove of information that could be the source of some fascinating research. Does this study signal the start of a new era where researchers will be able to have access to profiles? Will Facebook users, often worried about privacy, stand for this?

  • Watts on the problems in past replications of Milgram’s original experiment:

The problem that all of the experiments have had—and the problem that we’re trying to address with this one—is that you never really know what the ground truth is. You know that there’s some network out there involved that connects people, and you know that messages are being passed along on top of this network. The problem is because you can’t see the network underneath them, you don’t know whether people are making the right choices, you don’t know if the chains are as short as possible, and you don’t know why the chains that aren’t completing are stopping.

The major difference here is that Facebook [is] the network over which these messages are being passed. We can see through Facebook how everyone is really connected to everyone else. We can see whether people can actually find these short paths. In previous experiments you were missing this background picture, but now we have the background and we can run the experiment on top of it.

It sounds like past experiments allowed researchers to see the outcome – how many letters reached the target – but didn’t allow them to trace out the paths, either successful or unsuccessful. Being able to see behind the curtain could also reveal some insights about the speeds of certain networks.

  • On whether the data is representative:

There are two issues here. You might be concerned that the Facebook network is somehow an unrepresentative sample of the real social graph of the world. The other concern is the people participating in the sample might be an unrepresentative sample of Facebook. I’m not worried about the first concern. Facebook has 750 million users. If it works on Facebook, it’s increasingly difficult to argue that it wouldn’t work for the rest of the world. But the second problem is one that we’re concerned about. It’s really just a matter of getting a broad enough recruiting effort.

I bet there are people who could make a good case that this data is not representative. These same issues plague web surveys: who has consistent access to the Internet and who can be recruited? I would guess that Facebook still skews younger and more educated than the general population.

Watts suggests the results will be published in an academic journal. It will be interesting to read about the outcome and how this is viewed by academics.

Should you worry about your pacemaker, baby monitor, or garage door opener being hacked?

Posted on by

I ran across a story about five common objects that can be hacked: a pacemaker, baby monitor, automobile, garage door opener, and brain.

Here is my problem with this story: it doesn’t give you any indication about how serious these problems are. Perhaps this is simply meant to be informational: certain common devices can be hacked. But the tone of the article goes beyond this and suggests that mischief can take place and people should replace older items that are easier to be hacked. Here is the question that really should be asked: how likely is it that any of these items will be hacked? Should people with pacemakers really be worried? What is the relative risk of paying less for an unencrypted baby monitor?

Without this information, this article fits a similar narrative of crime stories where readers assume or develop the idea that these are common occurrences when they really are not.

Redoing Milgram’s degrees of separation experiment with Facebook

Posted on by

Stanley Milgram is best known for one particular experiment but another of his experiments is being replicated with new technology:

Yahoo and Facebook are setting out to test the hypothesis that anyone in the world is connected to anyone else in just six steps.

The experiment aims to prove or disprove that which was first suggested by Harvard sociologist Stanley Milgram when he asked 300 people to get a message to a Boston stockbroker using their personal networks.

Only about 60 of the messages reached their target, with the average number of steps in the chain being six – coining the phrase ‘six degrees of separation’.

Yahoo’s research department is aiming to replicate that experiment, this time using Facebook, which has 750 million users worldwide.

If you go to the official page, you can then choose to participate. But before you can, you have to agree to a “Terms of Use” and four other statements. This is essentially the “informed consent form” for the experiment.

Also, the “Terms of Use” provides this description of the project:

The purpose of this study is to test a long-standing theory in sociology that everyone on Earth is connected together in a giant social network. In this experiment, participants called “Senders” forward messages to their Facebook friends in an attempt to reach a given “Target” individual, about whom they are given certain identifying information, in the shortest number of steps possible.

I can’t say that I have heard this specific sociological theory but I would be interested to see the results.

If you want to read a short (several paragraph) description of Milgram’s initial experiment, find it here.

Since corporations like Yahoo, Google, Facebook, and others are sitting on treasure troves of data, can we expect to see more experiments like this in the future?

From luxury item to throwaway good: cable TV

Posted on by

Following up on Joel’s post from Wednesday, Figures from the last quarter suggest the cable TV industry continues to lose customers:

The phone companies kept adding subscribers in the second quarter, but Dish lost 135,000. DirecTV gained a small number, so combined, the U.S. satellite broadcasters lost subscribers in the quarter — a first for the industry…

Sanford Bernstein analyst Craig Moffett estimates that the subscription-TV industry, including the untallied cable companies, lost 380,000 subscribers in the quarter. That’s about one out of every 300 U.S. households, and more than twice the losses in the second quarter of last year. Ian Olgeirson at SNL Kagan puts the number even higher, at 425,000 to 450,000 lost subscribers.

The second quarter is always the year’s worst for cable and satellite companies, as students cancel service at the end of the spring semester. Last year, growth came back in the fourth quarter. But looking back over the past 12 months, the industry is still down, by Moffett’s estimate. That’s also a first.

The article goes on to mention a number of reasons for this: a bad economy so consumers are cutting back, younger people don’t see the necessity of cable, and there is a lot of content available through the Internet.

More interesting to me is the idea that cable TV is no longer the luxury good that it once was. Once the industry began in the 1970s and later consolidated, cable moved from being a rarity to being a necessity. As late as mid 2009, “11% of U.S. TV homes only have the capability to receive TV reception “over the air”.” Having cable simply became part of how Americans spend their disposable income. Cable became prism through which many Americans viewed the world. Certain channels arose, such as MTV which has been getting a lot of attention recently because of its 30th anniversary or ESPN which was the subject of an interesting book, and became part of the national consciousness. These channels, for better or worse, came to represent American culture and were exported around the world. I wonder if having cable at home signaled a middle-class lifestyle even if other traits don’t match this standing.

But now the world may have moved on. (At the same time, despite all the articles suggesting people stop paying for cable, bad economic times, and more competition, the drop in subscribers was only 0.2-0.3%.) How exactly will cable companies convince people that their product is a necessity, particularly among the younger generations? What will be the new narrative regarding cable that will push people to include this in their lives?

The first Apple sociology app?

Posted on by

I didn’t see this coming:

Wiley-Blackwell, the scientific, medical and scholarly publishing business of John Wiley & Sons, Inc., is launching its first mobile application in Sociology, accessible via iPhone, iPad, and iPod touch.

Wiley-Blackwell Sociology Spotlight is a must-have app for all Sociologists. It shines a powerful spotlight on Sociology, enabling you to instantly read all of the latest news and developments in the field. Whether you want to keep track of broad trends across the discipline or focus in on a subfield, Sociology Spotlight is an essential tool for your research and teaching.

A few questions:

1. Is there a market for this? It does appear to be free…

2. Might this set off an arms race among publishers to make their content available through apps?

3. The iTunes preview app page suggests certain articles have “video abstracts.” Is this the new wave of the future?

The threat to iOS

Posted on by

Ars Technica has a post about Apple’s latest response to a lawsuit filed by Lodsys, a reputed patent troll, against of Apple’s app developers:

Lodsys began threatening both iOS and Android developers with lawsuits in May if the developers didn’t pay licensing fees for its claimed in-app-purchasing-related patents. Many independent developers lack the financial and legal resources to litigate a patent infringement claim, so a number of iOS developers began a campaign to get Apple to help, threatening a boycott of in-app purchasing if only to avoid such legal threats.

Lodsys acquired its four patents from former Microsoft CTO Nathan Myhrvold’s Intellectual Ventures patent holding company. It turns out that Apple already has a license to those patents by virtue of an investment deal in Intellectual Ventures. That deal gave Apple (among other companies, including Google) a license to some 30,000 or so patents under Intellectual Ventures’ control.

(In case you missed it, this is the same Intellectual Ventures that was the subject of a recent This American Life episode, which has sparked—to put it mildly—quite a discussion around the blogosphere.)

If Apple isn’t successful in defending its developers here, the whole iOS app ecosystem may be in jeopardy.  As innovative as Apple has been in creating and updating iOS devices—iPhone, iPod Touch, iPad—over the past few years, a lot of their success is due to non-Apple creativity.  There’s no way that Steve Jobs’ company could have created 425,000 apps over the past four years, and those apps are a (the?) main selling point for consumers purchasing iOS.

If Apple’s licenses with Lodsys/Intellectual Ventures don’t cover its developers and those developers can get sued one by one, two things will probable happen.  First, the largest/financially strongest developers will (like Apple itself) reluctantly pay off the patent trolls, surviving by ultimately passing the costs onto consumers.  Second, small developers will go out of business.

New “friend prediction program” based on the places one visits

Posted on by

Three researchers have developed a “friend prediction program” that accounts for the locations someone visits:

Through an extension of the “long-standing sociological theory” people who tend to frequent the same places may be similarly-minded individuals, Salvatore Scellato, Anastasios Noulas, and Cecilia Mascolo, have developed a friend prediction program based on the places people visit.

Sites such as Facbook and LinkedIn often suggest friends based on a ‘friend of a friend’ approach but now it could be based on where users ‘check in’.

The system would also use different weightings for places like gyms – where people frequent – as opposed to airports, where people visit only occasionally…

They discovered about 30 per cent of social links developed because of people visiting the same places.

It sounds like location is not everything when it comes to forming friendships but it does play an important role.

I don’t know if many people think about why they are friends with the people they are friends with but I suspect one argument might emerge: we choose to be friends with our friends. Such a story would fit with tales we tell about finding romantic partners. It gives agency to each participant and suggests each person found the other to be likeable. But perhaps another story might emerge as well: we just sort of started hanging out together. This story would be tied to proximity: people who are placed or place themselves in particular places or situations are more likely to become friends. Some classic examples include being in a series of high school classes together, being assigned to certain roommates early on in college, starting work at a particular company. In each of these situations, people still have some room to choose their friends but their pool of possible friends is more limited by structural forces. Theoretically, you could be friends with anyone but realistically, you will come in contact with a more limited number of people in life.

Perhaps some still think that the Internet can reduce the impact of proximity by connecting people who never or rarely are in the same location. However, research suggests that most SNS (Facebook, Myspace, etc.) relationships are based on existing off-line relationships. The power of proximity will last for some time, even if most people don’t think about it.

60% of British teenagers, 37% of adults “highly addicted” to their smartphones

Posted on by

A recent British study found that many teenagers are “highly addicted” to their smartphones:

Britons’ appetite for Facebook and social networks on the go is driving a huge demand for smartphones – with 60% of teenagers describing themselves as “highly addicted” to their device – according to new research by the media regulator, Ofcom…

The study, published on Thursday, also shows that smartphones have begun to intrude on our most private moments, with 47% of teenagers admitting to using their device in the toilet. Only 22% of adults confessed to the same habit. Unsurprisingly, mobile-addicted teens are more likely than adults to be distracted by their phones over dinner and in the cinema – and more would answer their phone if it woke them up…

Of the new generation of smartphone users, 60% of teenagers classed themselves as “highly addicted” to their device, compared to 37% of adults.

Ofcom surveyed 2,073 adults and 521 children and teenagers in March this year. The regulator defines teenagers as aged between 12 and 15, with adults 16-years-old and above.

Perhaps these results are not that surprising but it leads to several thoughts about addiction:

1. Since this is self-reported, couldn’t the percentage of teenagers and adults who are “highly addicted” actually be higher? If asked, how many people would admit to being “highly addicted” to things that they were actually addicted to?

2. That this many people were willing to say that they are “highly addicted” suggests that this addiction is probably considered to be normal behavior. If everyone or most people are actually addicted to using their smartphones, doesn’t this turn into a norm rather than an addiction in the eyes of the public? In twenty years, when these teenagers are the ones running these surveys, they may not use the same language or terms to describe phone/mobile device/computer use.

Google+ a “sociologically simple and elegant solution”?

Posted on by

According to one reviewer, Google+ takes advantage of sociological principles with its circles:

You also don’t have to ask anybody to be your “friend”. Nor do you have to reply to anybody’s “friend request”. You simple put people into the discrete/discreet spheres they already inhabit in your life…

Now, if you had asked me which company I considered least likely to come up with such a sociologically simple and elegant solution, I might well have answered: Google.

Its founders and honchos worship algorithms more than Mark Zuckerberg does. (I used to exploit this geekiness as “color” in my profiles of Google from that era.) Google then seemed to live down to our worst fears by making several seriously awkward attempts at “social” (called Buzz and Wave and so forth).

But these calamities seem to have been blessings. Google seems to have been humbled into honesty and introspection. It then seems to have done the unthinkable and consulted not only engineers but … sociologists (yuck). And now it has come back with … this.

Why exactly do algorithms and sociological principles have to be in opposition to each other? It is a matter of what informs these algorithms: brute efficiency, sociological principles, something else…

Ultimately, couldn’t we also argue that the sociological validity of Google+ will be demonstrated by whether it catches on or not? Facebook may not be elegant or “correct” but people have found it useful and at least worthwhile to join(even if some loath it). Perhaps this is too pragmatic of an answer (if it works, it is successful) but this seems to make sense with social media.

This reminds me as well of the idea expressed in The Facebook Effect (quick review here) that Facebook wishes to reach a point where people are willing to share their information with lots of people they may not know. If this is still the goal, Google+ then is more conservative in that people can restrict information by circle. I suspect it will be a while before a majority of people are willing to go the route suggested by Facebook but perhaps Facebook is being more “progressive” in the long run by trying to push people in a new direction.
