Worst job ever?

July 19th, 2007

Unclear why exactly:), Michael Froomkin asks the question:

What would be the most unattractive job in the regular economy? I’m not talking about the objectively least-well paid or statistically most dangerous, or most unpopular (car salesman?). I mean, what job would you least like to have. No fair saying subsistence farmer in Darfur either — I mean in the US (or other developed economy).

His response: toll booth attendant.

As I note in the comments to his post, I won’t answer, because I prefer to think about aspects of jobs I like. His post reminded me, however, of having heard once that toll booth operators have the highest suicide rate among various occupations. I decided it was time to check on this. There doesn’t seem to be much out there to support the claim. Not surprisingly, there are a lot of methodological challenges to studying the relationship between occupations and suicide rates. This piece does a good job of mentioning several of them from lack of occupational information on death certificates to numbers being too small by category for comparison. From what I’ve read after a quick search, it’s fair to say the rumors I have heard about the above relationship are pretty much unsubstantiated.

Long before becoming a card-carrying sociologist, I was interested in suicide rates.* This may have had to do with the fact that I grew up in a country with one of the highest rates of suicide. According to 2003 figures, Hungary is #6 on the list (interesting group – bottom right corner when you click through), but in the 1980s when I was growing up there, it may have been #1 judging from the figures for the other countries high on the list since some of their rates seem to have gone up while Hungary’s declined considerably [pdf] in the last couple of decades. I doubt there are many Hungarians who don’t know of people in their immediate circles who either committed or at least attempted suicide (I knew several before graduating from high school), but perhaps this is true elsewhere, too.

All of which is obviously not to say that worst job ever equals suicide. It’s just a connection I made after reading about Michael’s candidate for the distinction.

[*] Yeah, yeah, maybe I became a sociologist, because I find questios of this sort intriguing.

Book title bleg

July 17th, 2007

The edited volume on research methods that I mentioned earlier is shaping up nicely and I’ll be shipping it off soon. However, I’m still not sure about the title and subtitle, and was hoping for some input from anyone who’s willing to give it some thought. This is what I’m working with now:

Research Methods from the Trenches:
The Nitty-Gritty of Empirical Social Science Research

However, having “research” in there twice doesn’t seem right. Any thoughts on either the first or the second part?

As a reminder, the chapters in this book provide helpful behind-the-scenes accounts of doing empirical social science research for a wide range of methods such as use of secondary large-scale data sets, interviews, observations, experiments and historical documents. The unique contribution of this collection is that it provides readers with a realistic idea of what to expect when embarking on empirical investigations by offering richly detailed descriptions of the logistics of individual research projects. The volume draws on the experiences of recent successful dissertation writers and young scholars doing cutting edge research in their respective social scientific fields.

If someone comes up with a title I end up using, I’ll happily send the person a copy of the book and will think of some additional gesture of gratitude. (Time to create some E-Blog stuff? Maybe I can think of something more useful.:) Thanks!

Random thought: if you wanted someone to take care of your pet, wouldn’t you pay for food up front?

July 15th, 2007

Sometimes I get a kick out of reading classifieds and so have been clicking through to some of the Marketplace ads on Facebook. I just read one where the advertiser is looking for a catsitter and ends the ad with the following:

“I’ll pay for the service, as well as litter and food on return.”

I may be reading this incorrectly, but it seems to suggest that the owner of the pet is asking the catsitter to pay for litter and food out of pocket (for three weeks) before being reimbursed, not to mention the burden of acquiring those materials. Is that reasonable? Doesn’t seem right to me. I’d leave the anticipated amount of litter and food before I left.

Speaking at Wiki Wednesday this evening

July 11th, 2007

For those in the Bay Area, I thought I’d mention that I’ll be giving a talk at Wiki Wednesday this evening at 6pm. The topic is digital media use by youth. Feel free to come by. Also, feel free to join the group at other times in the future, these meetings are held every month.

Something’s phishy? There may be more than money at stake…

July 7th, 2007

The term “phishing” refers to the malicious practice of trying to extract sensitive information (such as passwords) from users. Compared to numerous other Internet-related terms, “phishing” is one of the least understood ones among users. I have found this in my work as have others in theirs. Of course, it may be that people understand the concept of phishing without knowing it is called as such. It is difficult to do large-scale data collection using more elaborate methods, but I implemented some related questions on a survey recently taken by over one hundred students who were randomly sampled from a diverse group. (See the end of this post for details about the data set.)

In the context of a larger study, I showed participants three hypothetical emails and offered several options for how they might proceed (respondents could check off several actions such as “delete it”, “ignore it”, “forward to tech support with a question”, etc.). When shown an email that looked very much like the one that comes from the IT department of the university (one that would not be hard to replicate by someone with malicious intent) over half of respondents said they would “follow the instructions outlined in the email”, which included going to a Web site and entering their username and password. Even more students said that they would “click on the links in the message and follow the instructions on those pages”. Less than 15 percent checked off the option of contacting tech support with a question or reporting the email as abuse. And in the open-ended field where respondents could explain what else they might do, only one student described actions that suggested the potential problem with the email. This among the generation that is supposedly savvy about digital media. See my forthcoming paper on The Role of Expertise in Navigating Links of Influence for more on this (especially pp. 12-19.).

When I talk to my students (at a different school than where the above study was conducted) about online privacy and security issues, and ask them about the potential implications, the usual response is about financial concerns: credit card numbers stolen, money lost. However, as I try to remind them several times throughout the course, financial issues are not the only ones at stake when managing one’s identity and actions online. For example, in the realm of health and politics one can easily come up with examples of cases where third parties should not have access to our information.

And then there is reputation. I have noticed some troubling incidents on Flickr recently and wanted to write a post about these experiences to remind people about the importance of being vigilant. Don’t stop reading just because you are not a Flickr user, by the way. These same issues could occur on lots of other sites as well.

Flickr is a photo-sharing community site where people post photos and often comment on others’ images. These comments sometimes include cute little awards that let you add your photo to an invitation-only group or whatnot. Recently, I received such a comment on one of my photos and clicked on the link included within it. This led me to a login screen seemingly still within Flickr. The people behind that site did a very good job replicating Flickr. You had to be very conscious of your actions not to proceed and follow what you were being instructed to do, namely, enter your Yahoo!/Flickr username and password.

Lucky for me, I did realize that there was something phishy going on here. I was already logged into Flickr so this login request did not make sense to me. I checked the location bar of the browser, and as expected, it did not say flickr.com/etc. Then I did a search for phishing on Flickr groups and confirmed that this was not something I wanted to pursue. Others had encountered similar issues and had already reported them so hopefully the admins were aware.

So what could one do with the username and password of Flickr users who were not as cautious or who simply did not realize what might be going on? First, one’s Flickr username and password is the same as one’s Yahoo! ID and password so it allows access to one’s email account and all other associated services, none of which is desirable. Within Flickr itself, it allows the malicious user to post comments on others’ photos using the account.

And that is precisely what I experienced this morning. Click here for a screen shot of a picture I posted and the comment that followed immediately after. Note that this comment came from someone who is not on my contacts list and whose account I had never seen as far as I recall. The comment on my photo of a Dublin door reads:

Hi,

Someone at RAMCON said you sell nude images of children on flickr(loldee etc..) and i was just wondering(if this is true) then how much do you charge and what payment methods you accept?

Thanks.

There is very minimal chance that someone from a paid account would leave such a message publicly on a photo.

Searching on Flickr, I see that others are experiencing the same issue with the exact same message, but using different people’s accounts. This can be really damaging to the person whose account is used for such messages especially if this person does not realize or does not understand what is going on. Already several people have reported the person participating in that discussion thread accusing him of having left at least three such messages.

So I thought a reminder was in order: before entering your username and password anywhere, be sure to check that you are on the Web site you think you are on, look at the address of the Web site in the browser and if it is not the one you expected then beware.

[*] Details about the data set: In February-March, we administered a paper-pencil survey to students in the one class at the University of Illinois, Chicago (UIC) that is required of all students thus posing no selection bias as to who was in the sampling frame from the university. UIC is one of the most ethnically diverse research university campuses in the US. We have a 98% response rate of the 85 course sections, and an 82% response rate of all students enrolled in the class. The survey data about understanding the term “phishing” represents the responses of 1,236 participants. We used stratified sampling (on gender and user skill) for the follow-up observational study (March-May, 2007) that also included a short additional survey. We achieved a 58% response rate on that portion of the study with 103 students participating.

Thanks to the MacArthur Foundation for supporting this work.

How quickly fire spreads

July 5th, 2007

Before I get evacuated (not a completely crazy idea with the sheriff right outside my office), I thought I’d post just how quickly fire can spread depending on the circumstances.


How quickly fire spreads

I realize those are not on the same scale, but the surrounding trees should help identify the areas. Understand that I was just trying to do some work this afternoon and then headed out periodically to take some pictures. I didn’t set up shop for a sequence.

The distance between the fire and the nearest road is quite big so eventually the firetrucks just had to head up on the hill. By the time I finished taking photos that entire patch was dark although it looked like the flames had subsided. Of course, that’s just the part I can see, chances are there is lots of action invisible to me from here.

Now I’m going to try to get back to work, helicopters notwithstanding.
