For the calculation of shift dues, there are two considerations.
1) The length of time of the various shift configurations (2 person, 4 person no trainees, 4 person with trainees, plus period coordinators/QA shifts)
2) The percent occupancy of the training shifts

For many years, 2) has hovered about 45%, which is what we used to calculate the dues.  Since STAR gives credit for training shifts (as we should) this needs to be factored in or we would not have enough shifts.

The sum total of shifts needed are then divided by the total number of authors minus authors from Russian institutions who can not come to BNL.

date                  weeks           crew           training           PC           OFFLINE          
11/26-12/10    2                  2                      0                  0           0           
12/10-12/24    2                  4                      2                 1            0   
12/24-6/30      27                4                      2                 1            1   
7/02-7/16        2                  4                      0                 1            1   

Adding these together (3x a shift for crew, 3x45% for training, plus pc plus offline) gives a total of 522 shifts.
The total number of shifters is 303 - 30 Russian collaborators = 273 people
Giving a total due of 1.9 per author.

For a given institution, their load is calculated as # of authors - # of expert credits x due -> Set to an integer value as cutting collaborators into pieces is non-collegial behavior.

However, this year, this should have been:
date                  weeks           crew           training           PC           OFFLINE          
11/26-12/10    2                  2                      0                  0           0           
12/10-12/24    2                  4                      2                 1            0   
12/24-6/02      23                4                      2                 1            1   
6/02-6/16        2                  4                      0                 1            1   

Adding these together (3x a shift for crew, 3x45% for training, plus pc plus offline) gives a total of 456 shifts for a total due of 1.7 per author.

We allowed some people to pre-sign up, due to a couple different reasons.

Family reasons so offline QA:
James Kevin Adkins
Jana Bielčíková
Sevil Selur
Md. Nasim
Yanfang Liu

Additionally, Lanny Ray is given the first QA shift of the year as our experience QA shifter.

This year, to add an incentive to train for shift leader, we allowed people who were doing shift leader training to sign up for both their training shift and their "real" shift early:
Justin Ewigleben
Hanna Zbroszczyk
Jan Vanek
Maria Zurek
Mathew Kelsey
Kun Jiang
Yue-Hang Leung

Both Bob Tribble and Grazyna Odyniec sign up early for a shift leader position in recognition of their schedules and contributions

This year because of the date of Quark Matter and the STAR pre-QM meeting, several people were traveling on Tuesday during the sign up.  These people I signed up early as I did not want to punish some of our most active colleagues for the QM timing:
James Daniel  Brandenburg
Sooraj Radhakrishnan

3 other cases that were allowed to pre-sign up:
Panjab University had a single person who had the visa to enter the US, and had to take all of their shifts prior to the end of their contract in March.  So that the shifter could have some spaces in his shifts for sanity, I signed up:
Jagbir Singh
Eotvos Lorand University stated that travel is complicated for their group, and so it would be good if they could insure that they were all on shift at the same time.  Given that they are coming from Europe I signed up:
Mate Csanad
Daniel Kincses
Roland Pinter
Srikanta Tripathy
Frankfurt Institute for Advanced Studies (FIAS) wanted to be able to bring Masters students to do shift, but given the training requirements and timing with school and travel for Europe, this leaves little availability for shift.  So I signed up:
Iouri Vassiliev
Artemiy Belousov
Grigory Kozlov
