Design contest for bicycle valet parking rack: $250 prize
by Jim Sheehan 09 May '11

09 May '11

Hello, colleagues; The Ohio City Bicycle Co-op <http://ohiocitycycles.org/> has been valet-parking bikes<http://ohiocitycycles.org/index.php?option=com_content&view=article&id=24%3…>at community events for about 10 years. We have tried many different solutions for portable parking racks for this service including shipping pallets and baby-crib rails, and are now using bike rims<http://ocbc.smugmug.com/Other/Earthfest-2007-2007-04-23/0614091211/83848784…>screwed to three furring strips<http://ocbc.smugmug.com/Other/Earthfest-2007-2007-04-23/0614091210/83848781…>, (the best photos we have are in these links). We're looking for a better solution, as we have several regular yearly events where we need to park up to 300 bikes. As the above-linked photos attest, portability is a primary consideration. Thanks to a grant from Cleveland Colectivo <http://www.clevelandcolectivo.org/>, we are offering $250 to anyone with a better idea. This contest closes May 11th. As explained in the contest parameters<http://ohiocitycycles.org/index.php?option=com_content&view=article&id=111:…>, any un-patented existing designs are eligible, and the winning design will be made available to all. Feel free to forward this email to any of your members, or other groups, who might benefit. Good luck!

Definition - Evidence Based Programs
by Andy Greif 09 May '11

09 May '11

Hi, Several of you have asked for a definition of "evidenced based programs." Please refer to the link listed below. Also below is part of a response I received from Charles Hammond. Take care. Andy "To answer your first question, I tend toward "research-based" youth programs, which imply the same scientific rigor as "evidence-based" programs, but encompass a wider range of definitions of evidence and scientific methods. Evidence-based usually connotes the attempt to reproduce intervention outcomes to the same truth standards as the physical sciences. I find much quantitative evidence in the social sciences to be questionable because the researcher has neglected to scrutinize his or her own bias sufficiently in creating the experimental design. I would consider some of the work done in bicycle programs in Seattle, Eugene, Indianapolis, and Boston, for example, to be research-based. But if you know of educational bicycle/mentoring programs that consider themselves evidence-based, I would very much like to know about them. The "production school"-type institution I'd like to help create would be strongly research-based, and I'm working on a proposal to a research foundation to create such a venture."

Bike Collective Wiki is under attack and we need your help.
by Jonathan Morrison 08 May '11

08 May '11

Rich Points at Community Cycles (Boulder, CO, USA) has complete control of the bikecollectives.org and bikebike.org domain names and hosting. However, the wiki has been under serious attacks from spammers ( http://www.bikecollectives.org/wiki/index.php?title=Special:RecentChanges&l…), so he needs your help to come up with solutions. Specifically? We need a MediaWiki security solution that still keeps the wiki easy to contribute, but keeps most of the spammers at bay and doesn't burn out the moderators. So far we have implemented ReCaptcha and email validation requirements on user creation, but it appears even those are being thwarted. Sincerely, Jonathan Morrison c: 801-688-0183

I just called Orontas and they'll be distributing their bicycle lubes, greases & degreasers through babac cyles distributors(Montreal) in the very near future. They just sent babac their first batch for distro 2 weeks ago so it should appear in the new babac catalogue & online very soon. It will be available in 20 L (5 gal) format so no need to bother with them pesky eco-aerosol cans and I reckon it'll be hella cheaper in bulk. I'd assume that they are available through other distributors as well, I just happen to use babac so that's all I asked about.
