Santa Fe dance weekend — practice party, youth, open mic, and English
July 25th, 2010
Four events, all successful, so much love!
The weekend began on Friday 7/23/2010 with a youth contra calling practice party at Mia Bertelli’s, attended by Riley and Maddy Mullany, Lauren Lamont, Richard and Laurel Wilson, and me. We developed a program of dancing and singing, each practiced calling dances, and learned from each other. Mia discovered the challenges of teaching the pre-contra lesson. Riley called his first contra and figured out quickly how he could improve his calling timing (keep an eye open for him calling more!). Lauren and Maddy are already well on their way. And Richard — how wonderful to show us clearer ways of teaching, direct us to the next thing we can work on, and demonstrate leadership and connection with the dancers. Mia hosted Riley, Maddy and me for the night and we were treated to amazing crepes by Miles with fresh sheep’s milk ricotta cheese that Mia made on the spot.
The first youth dance and singing event (facebook) on Saturday 7/24/2010 2-5 pm was generously supported (made free) by FolkMADS.org and the Santa Fe Odd Fellows. Thanks to Bill Cooper of the IOOF for getting us in the hall at the last minute and setting up sound for us. Callers were Maddy Mullany (16), Lauren Lamont (21), Mia Bertelli (20), and first-time callers Riley Mullany (14) and Abbey Schiffmiller (18). Karina Wilson (25) played fiddle for us, accompanied by 3 of the 4 Mullanys (Mom Marj played, too). Mia taught a Schottische and led singing in the middle of the afternoon, and at the end of dancing. I was concerned there would only about 6 people there, but we started with 12 dancers and were up to 20-25 young people at the height of the afternoon. I was amazed, enlivened, and encouraged! Everything was done by leaders 25 years and younger! I helped facilitate by making introductions and helping with some planning, but we can thank the youth leaders in our community for the calling, music, and singing that led to such a wonderfully successful day. Everyone would love to do it again! People learned about the event mostly by word-of-mouth in the network of friends in Santa Fe, and many made efforts to get more people to come. I have confidence another event will bring even more people!
Many people stayed for the potluck from 5-6 pm, and the singing from 6-7 pm. If done again, I’d have the afternoon event a little later and the potluck a little later.
I was asked to host that evening’s contra dance open mic. A few of our youth callers called another dance that evening (Mia, Lauren, and Abbey), as well as Bill Cooper, and I called several including one I wrote for Mia earlier that day, “Crepes with Ricotta“. Victory Chicken played old-time southern tunes for us. I’m feeling more confident in my calling, and loved working with the band.
Sunday was another first (for a long while), an English country dance in Santa Fe on Sunday 7/25/2010 2-5 pm that I organized with Bill Cooper. Would people come to an afternoon ECD in Santa Fe in the summer? I was worried again, but what a turn-out! Noralyn Parsons called to more than 30 dancers with a 5-piece band (Gary Papenhagen, violin; Bo Olcott, acoustic guitar; Deb Bluestone, violin and viola; Phyllis Doleman, violin; Dave Faires, electric bass)! I could not believe what a success it was. Noralyn called very fun and accessible dances so that even first-time ECDers had a great time, and a couple waltz mixers. People want to do it again and this event was again very encouraging for more SF ECD.
The Santa Fe and Albuquerque dance communities are vibrant, supportive of new projects, and show their support by committing, following through, and (most importantly) showing up! Sometimes I take risks and things don’t work out. Sometimes many other people come along with me on those risks, and maybe they still don’t go right. And this weekend felt like a major risk — a new youth dance that I helped organize (with Riley Mullany), an evening open mic I hosted, an ECD I organized (with Bill Cooper), a potluck, a practice session I pulled people together for (thanks for hosting, Mia)! But I was not alone. The young callers and musicians created a program hoping young dancers would come, Noralyn Parsons and Gary Papenhagen’s band created an English program with the hopes of dancers, Karolyn Wilson helped create advertisements, Deb Brunt advertised it on the email list, Jane Phillips put it on the FolkMADS.org website, FolkMADS and IOOF sponsored the events, and I thank others who contributed to making the weekend a success. Everyone must have believed enough that these new and uncertain events would be great because dancers came, had a wonderful time, and want more.
I want to help create opportunities for new leaders, and I am inspired by what we have already accomplished together.

A first substantial contra dance calling experience
May 9th, 2010
At the May 1st, 2010, Albuquerque contra dance, scheduled caller Richard Wilson handed me a special opportunity to call most of the evening. The evening started with Karina Wilson and I leading a waltzing workshop. Richard called the initial dance, gave me the rest of the first half, then Karina called the first dance of the second half and I called the rest. Something that worked well was using the circle waltz mixer we taught in the workshop to begin the waltz ending the first half. The mixer went around 5 or so times and by chance our original partner ended right in our hand, then the circle broke apart into a free waltz.
It’s a very special experience to come face-to-face with the things I can’t do while doing the very best I can. It’s me failing for the greater good, and to fail in public for the dancers is a powerful opportunity. I’ve felt wonderful support from the people in the contra dance and music community, and for them I want to do better at everything.
I’ve performed a postmortem on the dances I called using a program planning matrix and learned a lot of things I wish I had known before the dance. I did well to offer a lot of variety, we did a circle mixer, a scatter promenade mixer, a triple minor, the circle waltz, and tried to start the second half with a polska (but few people know how to dance the Scandinavian dances). There is plenty I would improve. I would not do a mixer in the second half again. There were 4 dances without a partner swing, and one dance without any swing — ouch! There were 5 dances with circling, 5 with chains, 5 with stars, 2 with down four in line, and an overwhelming 7 with do-si-dos. The dances were overwhelmingly easy. The matrix is really valuable for planning variety and for seeing all the I could have done better, just in terms of dance selection. This selection of dances would have been better suited for lesser-experienced dancers, but not the Albuquerque regulars.
What next? Call more, fail more, learn more, dance more, laugh more, love more.
The steps I’ll take until I learn something better are these. 1) Consider the dancers and musicians who will be at the dance. 2) Using the program planning matrix to improve variety and see how to build a program of dances that introduces new calls throughout the dance. 3) Practice calling with recorded music to decide on the words to use to teach and while calling. 4) Have some back-up dances if I need to modify for easier or slower-paced dances or up the complexity or pace. 5) Say less, do more, be brave and confident, trust and love the dancers, honor the musicians, sound crew, and everyone else who makes the dance great, ask for critical feedback to learn and improve, reflect, and go do it again!
Thanks to fiddler Gary Papenhagen and his band for their wonderful support of the waltzing workshops and making calling with them a fun and easy partnership. And thanks, FolkMADS!
Visions
March 15th, 2010
A few important areas of focus, reflecting what I’m doing and where I’m going.
Professional
Statistics for Stable Isotope applications
My vision is to be the recognized leader of statistical methods in stable isotope sourcing. This will be accomplished through publishing papers from my dissertation work, collaborations leading to publications on methodological extensions, and giving talks in university departments and at courses and conferences.
Postdoctoral fellowship at the Mind Research Network
At the MRN my vision is to be an exceptional statistician, a valuable member of Vince Calhoun’s team, and an expert on statistical methods applying to ICA and fMRI. This will be accomplished with thorough discussions and detailed answers to statistical inquiries, active curiosity about others’ work and how I may contribute, and careful study of existing ICA models and sound application of statistical principles.
My career goals at the MRN are to develop a broad and deep knowledge of the methods for analysis of fMRI data in particular, and brain imaging data in general, to publish carefully developed extensions in well-written papers, and make contributions to others’ work. This will be accomplished by dissecting the modeling details from published work and uncovering further details by contacting the authors, appealing to theoretical results and experimental confirmation before publicizing new methods, and helping others consider their methods, results, and interpretations.
Personal
Dance
My vision is to contribute more to the Albuquerque contra dance community and bring dance to more people, especially youth. This will be accomplished by making opportunities for new callers, writing and calling dances, leading and participating in workshops, helping make more dance and music opportunities to bring the community together, outreach efforts to introduce dance to more people, and always collaborating with our vibrant New Mexico dance community to make it happen.

Catch and Release and Catch
by Erik B. Erhardt, 2010.02.18
Becket, double progression to the right (reverse Becket progression)
Music: slow tempo, flowing through B1, can have punctuation on beat 4 in four measures in B2
[Pulses Call]
A1:
4 (with Neighbors across,) Box the Gnat
6 (into) Right-hand (wrist-grip) Star 3/4
6 (Gents turn over right shoulder,) Neighbor swing
A2: (catch)
8 (with Partner across, Ladies pass left shoulder taking right hand with Partner)
Gents Lasso Ladies [Partner], high then low (Ladies walk around twice, letting hands go behind the Gent’s back on second time around)
8 (into) Partner gypsy 1-1/2 (lades end on left, facing in)
B1: (release and catch)
8 1/2 Poussette (Ladies join both hands with Neighbor Gent, then push and pull the Gents as the Ladies move as a do-si-do relative to each other)
8 (while Ladies are backing up, gents catch partner with right hand and) Partner Swing
B2:
16 Zipper (across right-hand pull-by (no courtesy turn), turn (or hop) alone to right and with same-gender diagonal one person left pull-by, face in and repeat; end effect is to not pull by if no one on is on diagonal)
Dance Notes:
- Many dancers may be unfamiliar with a Lasso (Richard Wilson), Poussette (English country dance), and Zipper. Therefore, this dance may take a while to teach.
- Teaching Zipper: It is a series of pull-bys with four people. The person straight across is #1, to their immediate right is #2, and #3 and #4 are the next two to the right. Now pull-by across and use the held hand as a pivot, turn (or hop) to right and look on the close left diagonal for that next person with the left hand.
- The first three quarters of the dance turns to the right, so the zipper is a welcome relief to stop turning.
- I wrote this dance in the car driving to Stellar Days and Nights, 2010 talking about dance with Richard Wilson who mentioned Lasso and Poussette as rare moves. I called the dance there two days later and I thank Mary Devlin for providing calling feedback.
- This dance is for Tara Schneider who I befriended at Berea Christmas Country Dance School, Dec 2009.
Paper accepted: δ13C of soluble sugars in Tillandsia epiphytes vary in response to shifts in habitat

δ13C of soluble sugars in Tillandsia epiphytes vary in response to shifts in habitat.
Oecologia, Physiological ecology section, 2010.
I met Laurel at SIRFER 2008 where we enjoyed a wide range of stable isotope lectures and lab experience. She first used my software, SISUS, to estimate the proportion of C3 vs CAM photosynthesis of epiphytes. Our work and friendship led to the collaboration where we thought about and developed a model for the environmental factors affecting the phothsynthetic pathways of the species studied.
Abstract
We studied carbon stable isotopic composition (δ13C) of bulk leaf tissue and extracted sugars of four epiphytic Tillandsia species to investigate flexibility in the use of crassulacean acid metabolism (CAM) and C3 photosynthetic pathways. Plants growing in two seasonally-dry tropical forest reserves in Mexico that differ in annual precipitation were measured during wet and dry seasons, and among secondary, mature, and wetland forest types within each site. Dry season sugars were more enriched in 13C than wet season sugars, but there was no seasonal difference in bulk tissues. Bulk tissue δ13C differed by species and by forest type, with values from open-canopied wetlands more enriched in 13C than mature or secondary forest types. The shifts within forest habitat were related to temporal and spatial changes in vapour pressure deficits (VPD). Modeling results estimate a possible 4% increase in the proportional contribution of the C3 pathway during the wet season, emphasizing that any seasonal or habitat-mediated variation in photosynthetic pathway appears to be quite moderate and within the range of isotopic effects caused by variation in stomatal conductance during assimilation through the C3 pathway and environmental variation in VPD. Carbon isotopic analysis of sugars together with bulk leaf tissue offer a useful approach for incorporating short- and long-term measurements of carbon isotope discrimination during photosynthesis.
