Reasons Police Departments Should Consider Collaborating with Me

Much of my academic work involves collaborating and consulting with police departments on quantitative problems. Most of the work I’ve done so far is very ad-hoc, through either the network of other academics asking for help on some project or police departments cold contacting me directly.

In an effort to advertise a bit more clearly, I wrote a page that describes examples of prior work I have done in collaboration with police departments. That discusses what I have previously done, but doesn’t describe why a police department would bother to collaborate with me or hire me as a consultant. In fact, it probably makes more sense to contact me for things no one has previously done before (including myself).

So here is a more general way to think about (from a police departments or criminal justice agencies perspective) whether it would be beneficial to reach out to me.

Should I do X?

So no one is going to be against different evidence based policing practices, but not all strategies make sense for all jurisdictions. For example, while focussed deterrence has been successfully applied in many different cities, if you do not have much of a gang violence problem it probably does not make sense to apply that strategy in your jurisdiction. Implementing any particular strategy should take into consideration the cost as well as the potential benefits of the program.

Should I do X may involve more open ended questions. I’ve previously conducted in person training for crime analysts that goes over various evidence based practices. It also may involve something more specific, such as should I redistrict my police beats? Or I have a theft-from-vehicle problem, what strategies should I implement to reduce them?

I can suggest strategies to implement, or conduct cost-benefit analysis as to whether a specific program is worth it for your jurisdiction.

I want to do X, how do I do it?

This is actually the best scenario for me. It is much easier to design a program up front that allows a police department to evaluate its efficacy (such as designing a randomized trial and collecting key measures). I also enjoy tackling some of the nitty-gritty problems of implementing particular strategies more efficiently or developing predictive instruments.

So you want to do hotspots policing? What strategies do you want to do at the hotspots? How many hotspots do you want to target? Those are examples of where it would make sense to collaborate with me. Pretty much all police departments should be doing some type of hot spots policing strategy, but depending on your particular problems (and budget constraints), it will change how you do your hot spots. No budget doesn’t mean you can’t do anything — many strategies can be implemented by shifting your current resources around in particular ways, as opposed to paying for a special unit.

If you are a police department at this stage I can often help identify potential grant funding sources, such as the Smart Policing grants, that can be used to pay for particular elements of the strategy (that have a research component).

I’ve done X, should I continue to do it?

Have you done something innovative and want to see if it was effective? Or are you putting a bunch of money into some strategy and are skeptical it works? It is always preferable to design a study up front, but often you can conduct pretty effective post-hoc analysis using quasi-experimental methods to see if some crime reduction strategy works.

If I don’t think you can do a fair evaluation I will say so. For example I don’t think you can do a fair evaluation of chronic offender strategies that use officer intel with matching methods. In that case I would suggest how you can do an experiment going forward to evaluate the efficacy of the program.

Mutual Benefits of Academic-Practitioner Collaboration

Often I collaborate with police departments pro bono — which you may ask what is in it for me then? As an academic I get evaluated mostly by my research productivity, which involves writing peer reviewed papers and getting research grants. So money is not the main factor from my perspective. It is typically easier to write papers about innovative problems or programs. If it involves applying for a grant (on a project I am interested in) I will volunteer my services to help write the grant and design the study.

I could go through my career writing papers without collaborating with police departments. But my work with police departments is more meaningful. It is not zero-sum, I tend to get better ideas when understanding specific agencies problems.

So get in touch if you think I can help your agency!

The week at Stackexchange 5/21/2013 Edition

Posts I’ve found interesting during the week (or likely over longer periods!) at various forums I participate at.





SPSS Nabble Group

Hopefully I get more time to blog in the near future, but currently busy, busy, busy! Working on visualizing JTC flow data (presenting at ASC this fall), getting everyone to approve my prospectus, and I have a few more SPSS blog posts I have in mind (restricted cubic splines, visually weighted regression, and using Ripley’s K to analyze temporal crime sprees!)

The week at Stackexchange 4/28/13 Edition

I know several individuals have blog posts in which they list interesting other articles that happened during the week. Mine will be a bit of a different twist though. I participate in a few of the stack exchange sites (and the SPSS Nabble forum), and often I think a question is interesting, but don’t follow along closely enough to see an answer given. Another situation that happens is I give an answer, and I don’t see other answers to the same post. To help me, and bring greater attention to various posts I find interesting, I figured I would create a weekly listing of those particular questions (no guarantee the question had anything to do with the previous week – I’ll try not to be redundant though!)





I’ve just noted this because I’ve seen a ton of nice ggplot2 examples from the Didzis Elferts recently on stackoverflow.

My posts on CrossValidated Blog

I’ve made several guest posts on the (now) currently dormat Cross Validated Community Blog. They are;

The notes on making tables is IMO my most useful collection, with the post on small multiples coming in second. Other contributions currently include;

For those not familiar, Cross Validated is a stackexchange website where one can ask and answer various questions related to statistics. They are a large improvement over list-serve emails, and I hope to promote their usefulness and encourage individuals to either contribute to current forums and/or start new ones for particular areas. I also particpate on the GIS and Academia sites (as well as programming questions for SPSS and R on stackoverflow).

The blog is just an extension of the site, in that Q/A sessions are not well suited for long discussions. So instead of fitting a square peg in a round hole at times, I believe the blog is a useful place for discussions and greater commentary useful for the communities that aren’t quite well placed in Q/A. Unfortunately, community up-take in the blog has been rather minor, so it is currently dormant. Feel free to stop by the Cross Validated chat room Ten fold if you are interested in contributing. I hope to see the blog not die, but IMO there isn’t much point in any of the current people to continue to contribute unless there becomes greater community contribution from other individuals.

My experience blogging in 2012

I figured I would write a brief post about my experience blogging. I created this blog and published my first post in December of 2011. Since then, in 2012, I published 30 blog posts, and totaled 7,200 views. While I thought the number was quite high (albeit a bit dissapointing compared to the numbers of Larry Wasserman), it is still many more people than would have listened to what I had to say if I didn’t write a blog. When starting out I averaged under 10 views a day, but throughout the year it steadily grew, and now I average about 30 views per day. The post that had the most traffic in one day was When should we use a black background for a map?, and that was largely because of some twitter traffic (a result of Steven Romalewski tweeting it and then it being re-tweeted by Kenneth Field), and it had 73 views.

I started the blog because I really loved reading alot of others blogs, and so I hope to encourage others to do so as well. It is a nice venue to share work and opinions for an academic, as it is more flexible and can be less formal than articles. Also much of what I write about I would just consider helpful tips or generic discussion that I wouldn’t get to discuss otherwise (SPSS programming and graph tips will never make it into a publication). One of my main motivations was actually R-Bloggers and the SAS blog roll; I would like a similarly active community for SPSS, but there is none really that I have found outside of the NABBLE forum (some exceptions are Andy Field, The Analysis Factor, Jon Peck and these few posts by a Louis K I only found through the labyrinth that is the IBM developerworks site (note I think you need to be signed in to even see that site), but they certainly aren’t very active and/or don’t write much about SPSS). I assume the best way to remedy that is to lead by example! Most of my more popular posts are ones about SPSS, and I frequently get web-traffic via general google searches of SPSS + something else I blogged about (hacking the template and comparing continuous distributions are my two top posts).

Also the blog is also just another place to highlight my academic work and bring more attention to it. WordPress tells me how often someone clicks a link on the blog, and someone has clicked the link to my CV close to 40 times since I’ve made the blog. Hopefully I have some pre-print journal articles to share on the blog in the near future (as well as my prospectus). My post on my presentation at ASC did not generate much traffic, but I would love to see a similar trend for other criminologists/criminal justicians in the future. My work isn’t perfect for sure, but why not get it out there at least for it to be judged and hopefully get feedback.

I would like to blog more, and I actively try to write something if I haven’t in a few weeks, but I don’t stress about it too much. I certainly have an infinite pool of posts to write about programming and generating graphs in SPSS. I have also thought about talking about historical graphics in criminology and criminal justice, or generally talking about some historical and contemporary crime mapping work. Other potential posts I’d like to write about are a more formal treatment about why I loathe most difference-in-differences designs, and perhaps about the sillyness that can ensue when using null-hypothesis significance testing to determine racial bias. But they will both take more careful elaboration on, so might not be anytime soon.

So in short, SPSSer’s, crime mapper’s, criminologist’s/criminal justician’s, I want you to start blogging, and I will eagerly consume your work (and in the meantime hopefully produce some more useful stuff on my end)!

CJ blog watch! Any ones I’m missing?

I follow alot of blogs. Although I don’t personally write alot about criminology or criminal justice related matters (maybe in the future when I have more time or inclination), but I figured I would share some of my favorites and query the crowd for more recommendations.

So a few with general discussion related to criminology and criminal justice matters are;

Both sites are well known criminologists/criminal justicians. I am aware of a few blogs written by current/former police chiefs;

  • Tom Casady’s The Director’s Desk. Tom Casady is currently the director of public safety for Lincoln, Nebraska and was previously the Police Chief at Lincoln’s department for quite some time. Tom is also very active in a variety of criminology/criminal justice organizations (so if you go to a related conference there is a good chance he is around somewhere!)
  • Chief’s Blog by Chief Ramsay of the Duluth Police Dept in Minnesota.

There are also a few that are highly focused on crime mapping & analysis;

  • Location Based Policing by Drew Dasher. He is a crime analyst for the Lincoln Nebraska PD.
  • Saferview – crime, fear and mapping: A blog by a retired police officer who is a student at University College London.
  • Diego Valle-Jones: Although his blog has a wider variety of topics, he has a series of very detailed posts and analysis on violence in Mexico and central american nations. I know crime stats are frequent fodder for generic statistical demonstrations, but this is real insightful analysis. My favorite is his investigation into the validity of homicide data statistics.

Are there others I am missing out on or should know about? Let me know in the comments if you have other suggestions.

FYI – the title of the blog post was motivated by Hans Toch’s new book, Cop Watch.
