Qualified Search Controllers, Search Managers and Search Trainers

January 24th, 2010

One of the comments made following my piece on getting the search controllers assignment right was that a database of qualified search controllers and managers would be useful to “trainees” [for want of a better word...]

In truth what Johnnie Walker actually said was;

Rob, could you collate and list the qualified Search Controllers within ALSAR, so that people know who to speak to for help? (let’s not discuss whether this is an ALSAR function rather than a Re-search issue; JFDI!) [Read it here ...]

Unfortunately I do not have the time to find e-mail addresses for all the teams and waste time discussing with any of them whether this is a suitable activity, whether this comes under data protection and so on. This is not to say I’m adverse to collating such information – which let’s face it would be extremely useful to so many people and organisations.

So, from today, I will be keeping a database of search controllers, search managers and search trainers/instructors within the UK (or I suppose available in the UK).

If you as an individual wish to be on this database, (or if your team/unit wishes all its qualified members to be on the database), drop me an e-mail with details of your qualifications, courses taken and/or courses you can teach. If you include your contact details (along with which way you prefer to be contacted!) that would be helpful too!

I promise that this information will be kept in the strictest confidence and only released to members of recognised SAR teams/organisations and/or police forces if you agree.

It has been pointed out that my e-mail address is not published on the website anywhere – and I intend it to stay that way! If you do not have my e-mail address, put a comment asking for it and I’ll e-mail you! Anything else?

Getting the Search Controller Assignment Right (First Time!)

January 21st, 2010

According to ALSAR you are not qualified to manage or control a search unless you have passed an assessment to say you are competent to do so! I think this is quite right. I do not care how good a course you sat through – unless you can prove you have taken some of it in, you should not be making life or death decisions [and have no doubt that is what a search manager/controller does!]

I am always very pleased then, to receive people’s Search Controller’s Assessments after they have sat their UKLSI Course. Those that sit through the course and then believe they are somehow “qualified” to run a search are wrong!

However, very often delegates have a problem completing the assignment. This is generally not due to their not being able to do the work, or them being somehow incompetent. More often it is due to a misunderstanding of how to pass assessments. So here, exclusively, is my guide to passing your search controller’s assessment!

When you are given your assignment you are given a list of assessment criteria. This is your guide to what you need to do to pass. Write or say something about each point and you have a good chance of passing. Miss any of them and you CANNOT pass!

So number one on the check-list is “recognise common pitfalls”. Look at your two searches, see whether any of the common pitfalls Charlie Hedges wrote about were present. If they were, say so. If not, say something to the effect that none were present – you might like to explain one and what happened on the search to prove its worth.

Number two, “demonstrate understanding of the benefits of pre-planning”. If one of your searches was pre-planned state how this helped. If it wasn’t pre-planned state what help it would have been had it been pre-planned – what went wrong or took time that could have been prevented by pre-planning. Note on your pre-plan how it helps with the next search incident at that location.

Number three… well, hopefully you are seeing that pattern. The assessment is not there to be difficult – in fact the activities were deliberately chosen to be useful to you and your Unit. But in order to demonstrate your competence you must discuss everything on the assessment sheet!

Have no doubt it will be hard work. It will take some time – something none of us have much of! But if you want to run a search and make those decisions – I think you ought to at least put in the time and effort to prove you are up to it!

Hopefully, this will have helped some of you. If anyone wants to add something – please do…

Wabi-sabi and the Art of Search

January 20th, 2010

OK – I admit it. I need to get out more.

I read a book a while back on Leonardo da Vinci. It was saying something like we can think like this genius, by putting into practice these six or seven skills. I didn’t take too much notice but it came back to me the other day when reading something else. [I'll soon explain, don't worry.]

One of the skills you need, according to Michael Gelb in his book – How to Think Like Leonardo da Vinci [I went and found the reference like a good student!], is Connessione – a recognition and appreciation for inter-connectedness! So, I’m reading one of the books I got for Christmas – Living out LOUD by Keri Smith – when she starts talking about Wabi-sabi. Wabi-sabi, according to the book, is a “Japanese concept that speaks to the art of imperfection, and/or the willingness to accept things as they are.”

Amazingly, given my total distrust of anything even slightly esoteric and my inability to not say something when something is imperfect, I kept reading. Well, it was all about sketching a stick – and how after thirty minutes the “simple stick had become something living, moving and expanding”.

However, it did get me thinking about search – you’ll be glad and unsurprised to hear. It reminded me of something Ian “Max” Maxwell had said during one of his tracking courses and can be found in his book – Animal Tracks ID and Techniques - about Zoning In.

Once you surrender and become part of your surroundings you will have zoned in. You will now be able to hear every movement, every sound, see everything and feel everything around you…

Once you have zoned in for at least twenty minutes you will know the baseline for noises, bird song, activity, motion and insect life. You will also know the baseline for the ground, trees and shrubs in the landscape around you.

It is here that the tracker will detect any variation from the baseline, be it hearing, feeling, seeing, smelling and taste.

The good searcher – whether a tracker or an “ordinary” [although they are no such thing] foot searcher – finds things that are out of place; that shouldn’t be there; like the missing person. How do they do this? By “knowing” the environment they are searching well; knowing what the vegetation is like, knowing what the rubbish should be like, just “knowing” the area and something out of place.

This was what the original SEBEV clue field was all about – before its meaning was lost in time – seeing those things that were out of place.  I’m sure this exercise, or a similar one, does have a place in training. We do NOT search for clues and an excellent trainer would be needed to run this session and not have it slow down to a snail’s pace “searching” for clues. BUT [note the BIG but!), but if we could find a way to expand searcher’s knowledge of what is and isn’t right in the environment this would be a very worthwhile exercise.

What do you think?

Elements of the Optimal Search Problem

January 19th, 2010

Lawrence Stone defined the elements of the optimal search problem in his 1986 book, Theory of Optimal Search.

This was paraphrased extremely well by Cooper, Frost and Robe in their 2003 report – Compatibility of Land SAR Procedures with Search Theory as quoted below;

A probability density distribution on search object location and state (so the probability of containment, POC (a.k.a. POA for “probability of area”), for any subset of the possible locations and states can be estimated),

A detection function relating the probability of detecting (POD) the object if it is in a searched area to the density of the searching effort expended there,

A known finite amount of available searching effort, and

An optimization criterion of maximizing probability of finding the object in a desirable state (probability of success or POS) subject to the constraint on effort availability.

I will endeavour to simplify further. In order to need and/or use the mathematics of search theory you require four essential elements.

  1. The ability to predict the likelihood that an object is in any particular search area or region. This might be done using sophisticated computer software working with the latest missing person behaviour statistics, or could be as simple as a coming up with a consensus within the search planning team.
  2. The ability to calculate the likelihood a given search resource will have of finding the object if it in the area being searched – unfortunately we can’t ask how many clues would you have found! [See my definition of POD for a brief explanation of why]
  3. A limited but known amount of search resource – when do you ever get too much search resource?
  4. A method of calculating the best way to use the search resource to maximise the chances of finding the search object as quickly as possible.

I’ll look in detail at each of these in further posts.

Play in Search Training

January 7th, 2010

The recent snow and yet another Christmas book (Living Out LOUD by Keri Smith) has got me thinking about play.

As was briefly discussed in the comments about graveyard humour following my report on ALSAR at the Dartmoor Rescue Training Exercise, fun and humour are a perfectly natural defence mechanism for our brains. The question is; how well do training officers balance the “fun” and the serious training exercises?

So here are a few of my ideas for fun search training exercises;

1. Spot the fairy
Maybe not a winter activity but set up right I think you could have a great twenty/thirty minutes of fun with this. Find a location with lots of cover and dead ground. Dress up the biggest, manliest member as a fairy. See who can be the first to spot him jump up.
This is probably best mixed in with some visual training of the “find 20 objects hidden in the panorama in front of you” type!

2. Route and Path Race
Have three or four equal route and paths, or one long circular path. Place ten or more small objects along this path. Have the teams race along the path. Give points for speed, and number of objects found.

3. Quick Search
Set up the usual search exercise [See my series on planning search exercises]. However, instead of having one Search Controller and search teams – run two competing “search units” with a search controller and search  plan each. Have them compete to see who can find the misper first! This should help train search urgency!

4. Beat the Search Dog
Here’s a fun joint dog / foot search team training activity. Set up some search areas – send out foot teams and a dog team and have them race to try to find the waiting misper.

5. Rescue the Landrover
Why not hide a Landrover or similar on the search ground? Let the team(s) find it and “recover it to a place of safety”!

I’m sure you can think of lots more… How about another New Year’s resolution? To put in a “fun” exercise or activity every couple of months.
