Some very nice whitepapers discussing not only pbwiki and hosted systems but also why wikis are useful in an organization. There are also some very helpful case studies. Some people like to host wikis in-house but this requires a much larger measure of support and attention than a hosted site.

Many of these hosted sites have a lot of security measures to protect the integrity of the data. They also handle backups and hardware. They can often make a big difference with small companies. Particularly those that can not easily provide the time to support an in-house option.

Water (ab)use

water by azrainman
Can You Get by on Just 5 Gallons of Water a Day?:
[Via AlterNet.org: Coverage Areas]

A British woman attempts for a day what most in the developing world deal with all the time — living on just over 5 gallons of water.

And what does her in is having to flush a toilet. As mentioned in the article, it was pubic sanitation of water in the 1800’s that not only prevented major disease outbreak, it also allowed us to use/misuse large amounts of water. Waste disposal, such a major portion of public sanitation, uses a lot of water.

Since we are not going back to the old ways anytime soon, simply using some common sense may help. Don’t run the water if you do not need to. Take quick showers using water restrictor showerheads instead of a bath. Use instant hot faucets instead of wasting water waiting for the water to heat up.

If you must rinse dishes before putting them in the dishwasher, fill up the sink or use a tub. And make sure your toilet is in proper working order, without leaks.

Finally, ‘Let it mellow if its yellow. Flush it down if its brown’. Add a little lysol to the bowl to help disinfect. as the article makes amply clear, unnecessary flushes use a lot of water unnecessarily.

Fixing new math

math by SantaRosa OLD SKOOL
Keeping math abstract may make it clearer:
[Via Buzzworthy]

All those story problems and “real-world” examples of applied math may actually make it harder for kids to grasp abstract concepts, suggests a study out of Ohio State University.
[More]

Now they tell us. I have hated watching my son have to deal with lousy word problems when he was able to easily solve ones based on abstract math. I worked with him a lot but always felt it was a bad way to teach math. Looks like I was right.

Kangaroo Mother Care?

tree kangaroo by Timmy Toucan
Kangaroo mother care diminishes pain from heel lance in very preterm neonates: A crossover trial:
[Via BioMed Central - Latest articles]

Background:
Skin-to-skin contact, or kangaroo mother care (KMC) has been shown to be efficacious in diminishing pain response to heel lance in full term and moderately preterm neonates. The purpose of this study was to determine if KMC would also be efficacious in very preterm neonates.
Methods:
Preterm neonates (n=61) between 28 0/7 and 31 6/7 weeks gestational age in three Level III NICU’s in Canada comprised the sample. A single-blind randomized crossover design was employed. In the experimental condition, the infant was held in KMC for 15 minutes prior to and throughout heel lance procedure. In the control condition, the infant was in prone position swaddled in a blanket in the incubator. The primary outcome was the Premature Infant Pain Profile (PIPP), which is comprised of three facial actions, maximum heart rate, minimum oxygen saturation levels from baseline in 30-second blocks from heel lance. The secondary outcome was time to recover, defined as heart rate return to baseline. Continuous video, heart rate and oxygen saturation monitoring were recorded with event markers during the procedure and were subsequently analyzed. Repeated measures analysis-of-variance was used to generate results.
Results:
PIPP scores at 90 seconds post lance were significantly lower in the KMC condition (8.871 (95%CI 7.852-9.889) versus 10.677 (95%CI 9.563-11.792) p Conclusions:
Very preterm neonates appear to have endogenous mechanisms elicited through skin-to-skin maternal contact that decrease pain response, but not as powerfully as in older preterm neonates. The shorter recovery time in KMC is clinically important in helping maintain homeostasis.

You learn something new all the time. Now the term Kangaroo mother care makes sense, since kangaroos are born as what we would call a neonate. It is interesting that the pain response changes as the baby nears full term. Now when I meet a new mother, I can ask her if she practices KMC.

Answering questions

colon by Jef Poskanzer

You have probably noticed that a high fraction of scientific papers have colons in their titles. Several people have written humorous commentaries on this. Although these authors clearly see the use of colons as a growing trend, they did not present hard evidence for the increase in the usage of colons in the titles of scientific publications.

Out of curiosity, I thus wrote a small script to count the fraction of papers in Medline that have colons in their titles for each of the past 25 years. The result is shown in the plot below (note that the y-axis does not start at zero):

The conclusion is very clear: the fraction of titles with colons has increased linearly from 15% to 24% over the past 20 years. One could object that this effect may be explained by the increase in apologies (which often have a title “Retraction: “) or by the NAR special issues on databases and web servers (which contain hundreds papers with titles such as “YADB: yet another database”). However, these add up to less than 2% of the papers with colonized titles and are thus insufficient to explain the observed 9% increase.

A good database lets you answer questions that never occurred to the database creators. Why colons are increasing is a mystery but one that might be fun to answer. It is amazing that the curve is so linear for 25 years. Searching Medline is a nice way to discover interesting things about how scientists think. I never would have believed that close to 25% of the papers have a colon in their title.

These three posts run the gamut from exuberance to wonder to doubt to reconciliation:

A Breakthrough In Taxonomy?:
So Much For Taxonomies:
Taxonomies Again — What Behavior Do We Want?:
[Via A Journey In Social Media]

They describe the process of creating taxonomies for a group of communities, an attempt to create some order. The very rapid path this took, from the excitement of a brand new idea, its implementation and then the very rapid feedback all demonstrate the power of Web 2.0. Life moves faster.

The problem here is probably a very old one. Some people feel better with a described space, using tags that mean specific things. The tags define the space. Others like the space to define the tags. There will always be a conflict here, between those who want an orderly desktop and those who prefer an unorganized one, especially if both types are represented in the community.

Neither view has a monopoly on wisdom. As brought out here, it is operational the difference between a search and a browse. Tags make searches much easier and allows people to find the exact information they want. The path to the information is sharply defined.

Browsers like to take a less defined path to the information. They like little cul-de-sacs and interesting dead ends. The surprise of new spaces is innervating for them.

One group will always find what they are looking for. The other will be surprised at the novel things they happen upon.

The approach described here was not satisfactory to the users, they let people know and the leaders of the taxonomy project quickly tried to reel it back in and find figure out what to do. They pulled back and asked “What question are we trying to answer?”

They understood that the problem was really getting new users on board as quickly as possible. Here a taxonomy would help them get started. But there are other ways to help newbies that would not disrupt the established users. Now they can try to fix the real problem.

Web 2.0 approaches allowed them to reach this conclusion in just a few days, rather than months, something that happened in the Web 1.0 world.

We tried this at Immunex, with defined tags being used for research projects. The Bioinformatic people spent months putting together the applications to allow tags to be attached to research projects. They finally rolled them out and they were a failure.

The problem was that the users could not define the tags. They were created by some unknown person. So what happens when a new project did not have an appropriate tag? Do you try and use something close, even though it might corrupt the system? Do you leave it blank, subverting the entire purpose? How do new tags get added? Who decides that they should be?

The tags never really got fully utilized. Research moved too fast to rely totally on pre-defined tags. Different people would categorize the same project differently. Without flexibility, too many projects would just get tagged with ‘Other’ negating the whole purpose.

A useful system has to be respectful of the users. It has to be malleable enough to have both structure and flexibility. It would also encourage browsing as easily as it does searching. Not easy things to do. But EMC will get to it faster by using a Web 2.0 approach.

Getting people onboard

french flower by procsilas
Parlez Vous Twitter? Evangelizing Social Media In Your Nonprofit Organization and Paving the Way for Adoption:
[Via Beth's Blog: How Nonprofits Can Use Social Media]


This slide show from Stephen Collins make me think about teachingInternet Skills Workshops for Nonprofits that I used teach over dozen or so years ago. During a discussion about the merits of email versus the fax machine (I’m not kidding), someone shared this insight, “I feel like a stranger in a foreign country and I don’t understand the language.”It has stuck with me.

The slide show is from a session he did at BarCamp Sydney called “All You Do Is Talk Talk Talk.” He talking about building shared language and understanding in order to successfully introduce a change (adoption of social media principles and tools) in an organization.He suggests that resistance will remain because people don’t understand, feel stupid, don’t speak the language, don’t have a compelling reason for change, or feel insecure. The advice is don’t speak social media geek, speak in simple English, be a bridge, establish trust, and become the understanding guru.

The slide show provide some useful insights into getting people on board, including their concerns and other barriers to adoption. Very nicely done and a great presentation.

Open science 0.9 beta

The science exchange:
[Via Science in the open]

How do we actually create the service that will deliver on the promise of the internet to enable collaborations to form as and where needed, to increase the speed at which we do science by enabling us to make the right contacts at the right times, and critically; how do we create the critical mass needed to actually make it happen? In another example of blog based morphic resonance there has been a discussion a discussion over at Nature Networks on how to enable collaboration occurred almost at the same time as Pawel Szczeny was blogging on freelance science. I then hooked up with Pawel to solve a problem in my research; as far as we know the first example of a scientific collaboration that started on Friendfeed. And Shirley Wu has now wrapped all of this up in a blog post about how a service to enable collaborations to be identified might actually work which has provoked a further discussion.
[More]

Open Science is really in the very early stages. It may very well evolve into an important adjunct for research. Collaborations are the prime driver of much of today’s science.

Collaboration is difficult in some organizations. Without it, they will not be able to effectively solve the difficult questions in science today. The organizations that can harness effective collaborations will survive and flourish.

Currently, collaborations are usually set up using well known social networking skills honed through years of experience. Who you know is important. What Open Science holds the potential for, when it comes to collaborations, deals with who you don’t know.

OS can leverage an online community so that connections can be made that would have been difficult or impossible if face time was required. However, it will take a little work, like porcupines mating, to make this really effective.

Part of the reason for this is trust. Science has some free loaders, people who take short cuts. Not many but they can degrade interactions until trust is established. which takes a little time. Reputation is an important part of this trust.

There are many examples of peer reviewers abusing the process and scooping someone on a paper that they held up in review, giving the reviewer time to replicate the work in his lab and submit a paper.

Grant proposals have been abused in a similar fashion. Researchers have altered data in order to fit a preconceived hypothesis. Collaborating with such people is a possible danger without more information.

So trust and reputation will have to be a part of OS, particularly since the participants may not meet face to face. But reputation and trust are a common problem with many Web 2.0 approaches.

One way Web 2.0 surmounts this is the very openness and transparency that gives it power. Ebay, for example, would not work if people did not trust the seller to have the item and the buyer to have the cash. Being able to see how each rates the other help establish trust.

Research has shown that what is important in human social networks is not that the network prevents cheats or freeloaders from existing. It is that the network has a method for identifying them and expelling them from the network if they fail to change.

Now OS will not be like Ebay, which is a site of commerce. But the power of many eyeballs watching the interactions will help apply social norms to the most egregious behavior. A reputation lost in the open like this will be very difficult to untarnish.

Another important aspect of scientific collaborations is power, a very human trait. Scientists with power (i.e. large, well funded labs) sometimes have a very different view of a collaboration than those with a small lab and a single grant. People often tend to confuse large and well-funded with innovative.

Remember well funded does not always mean cutting edge investigations of important questions. Sometimes it means doing what everyone knows will work, just more of it with greater efficiency. Risk is many times found in the smaller labs, not the larger, something also seen in corporations. The unwillingness to take a risk, found in many large organizations, often make collaboration with smaller, risk-taking groups problematic.

But on the Internet, this sort of power is defused somewhat. There is a leveling effect, allowing many more researchers to have an equal voice. On the Internet, no one knows you are a dog. They also may not know whether you have a lab of 40 researchers and $10 million in grants. What will be important are your ideas and how you treat others in the network.

So, watch as this discussion happens out in the open, as it should. Become part of it if you can.

Paul’s Principles of Web 2.0

Spider by aussiegall

Web 2.0: Building the New Library
[Via Ariadne]

Paul Miller wrote this over 2 years ago but it amply describes the effects of new approaches will have on an area that lives by dispersing information. It is not the technology that will make a difference. It is an attitude, one that is almost as old as humankind.

Sharing helps the entire team, tribe or town. The collective intelligence of the group is only strong when the umber of information chokepoints is low.

Paul’s Principles of Web 2.0, as discussed here, still apply in almost any endeavor that must deal with information to succeed. Here they are:

  • Web 2.0 presages a freeing of data, allowing it to be exposed, discovered and manipulated in a variety of ways distinct from the purpose of the application originally used to gain access.
  • Web 2.0 permits the building of virtual applications, drawing data and functionality from a number of different sources as appropriate.
  • Web 2.0 is participative.
  • Web 2.0 applications work for the user.
  • Web 2.0 applications are modular, with developers and users able to pick and choose from a set of interoperating components in order to build something that meets their needs.
  • Web 2.0 is about sharing: code, content, ideas.
  • Web 2.0 is about communication and facilitating community.
  • Web 2.0 is about remix.
  • Web 2.0 is smart.
  • Web 2.0 opens up the Long Tail.
  • Web 2.0 is built upon Trust.

Well, I am sure I will be retired by the time this comes to fruition but I can hope, can’t I? The Eastside often gets the short end of the Puget Sound stick when it comes to commuter options but there has to be more things that can be done other than build more roads.

Openness helps everyone

Bursty science depends on openness:
[Via Science in the open]
An example of a social network diagram.Image via Wikipedia

There have been a number of interesting discussions going on in the blogosphere recently about radically different ways of practising science. Pawel Szczesny has blogged about his plans for freelancing science as a way of moving out of the rigid career structure that drives conventional academic science. Deepak Singh has blogged a number of times about ‘bursty science‘, the idea that projects can be rapidly executed by distributing them amongst a number of people, each with the capacity to undertake a small part of the project.
[More]

There will be many of these little experiments – using online conversations for scientific endeavors. Even inside an organization, having an online area to ask for help can be useful. Trying to use email for this purpose has little effect.

There are several ways to use Web 2.0 approaches to ask/answer questions. An online forum works well if it is substantially populated and active. A forum with a 3 month old unanswered question will not be very useful.

One approach that works is to have one person, or a small group, act as troubleshooters. They probably already exist in many organizations. They are the ones every one goes to when they have a problem in the lab.

They usually have a wide range of knowledge and often work to help people find a solutions to a research problem.

Have these people move online. A troubleshooting page on a wiki would allow questions to be asked. The troubleshooters have the opportunity to find answers. FAQs could be written to respond to the endless questions many troubleshooters receive.

Then when someone asks for some help, there is already a team with responsibility to find answers. And, because all this is open and transparent, the troubleshooters can finally get the well deserved credit they should.

Helping in the lab is generally invisible to others, particularly when evaluation time comes around. It is hard to document just what the help accomplished.

A troubleshooting wiki, on the other hand, would provide ample documentation on just what help was provided and the effect that help had on the organization. The ability to actually document who helps the organization move forward will be very valuable.
