Swap instructions: You are shown a table containing all the shifts currently assigned to you (or to your institution if you are a contact). Choose the ones you want to swap, then scroll down the page and select the period into which you would like to swap. Click 'Next' and you are presented with a list of options, given the constraints imposed by our swap rules (you can go back and change the target period if you wish). Select now the desired set and click 'Next'. You are asked to review and confirm the transaction. Click 'OK' and you are done - the new configuration will be shown on the screen.

Memberships: This person can not be deleted from this table because he/she is listed
as active in the CLAS membership database.
If he/she is no longer with your group, please email Bryan McKinnon
with the date when the person left your group. Once that information is
entered in the membership DB, you will have the option to delete the
person from the shift list. Find more details in the FAQ.

Time share: This is the fraction of the year the person
contributes to your institute's service work.
If someone joins say in March, their time share
would be 75 %, if a person leaves in June they
contribute 50 % etc.

Percentage done: The percentage done acts as a multiplicative
factor, e.g 0.2 FTE with 50 % done is 0.1 FTE.
For example a paper review half done may be
listed either as 0.1 FTE 100 % or as 0.2 FTE
with 50 % done. What matters here is only the
claimed FTE, which in both cases is 0.1

FTE Guidelines
: 1 FTE = 10 months or 0.025 FTE is approximately one week
A paper review takes 2 - 4 weeks (i.e. 0.05 - 0.10 FTE)
Maintenance of a cluster used by/for collaboration for
a perios of less than 2-4 weeks counts as 0.05 - 0.10 FTE.

Service Work Guidelines
: Scientific publications are not considered service work
Supervision of students doing service work is not service work
Grant applications are not considered service work
CLAS and CLAS12 service work should be kept separated

CLAS Online Interface
: CLAS online interface designed and implemented
by Dan Protopopescu. For questions and/or
user support please email shiftbot@jlab.org.

Reporting service work

Quick guidelines:

1 FTE = 10 months or 0.025 FTE is approximately one week.
The actual FTE is calculated by multiplying the FTE by the percentage done.
A paper review takes 2 - 4 weeks (i.e. 0.05 - 0.10 FTE).
Maintenance of a cluster used by/for collaboration < 2-4 weeks counts as 0.05 - 0.10 FTE
CLAS and CLAS12 service work should be kept separated

Not service work:

Membership Committee should not be added
Do not add paper reviews in the next year's estimate SoS
Scientific publications are not considered service work
Supervision of students doing service work is not service work
Grant applications are not considered service work

Here's the actual function used:

function getManpower($iid){

   // Don't count exempt members (maternity leave, other medical conditions)
   $total = mysqlResult("SELECT COUNT(name) FROM smembers WHERE institute='$iid' AND expert>=0");
   $experts = mysqlResult("SELECT COUNT(name) FROM smembers WHERE institute='$iid' AND expert>0");
   $xratio = $experts/$total;

   // Compare with the actual CLAS Membership DB numbers
   $today = date("Y-m-d");
   $mdb_tot = mysqlResult("SELECT COUNT(*) FROM Person, History, Institute WHERE"
              . " (History.start <= '$today' AND History.end >= '$today') AND (History.person = Person.id)"
              . " AND (History.classtatus = 'Term' OR History.classtatus = 'Full') AND"
              . " (Institute.id = Person.institute) AND (Institute.acronym = '$iid')", "membership");
   if($mdb_tot > 0 && $mdb_tot < $total){
     $total = $mdb_tot;
     $experts = floor($xratio*$total);
   }
   $workers = $total - $experts;

   return array($experts, $workers);
}

CLAS Speakers Committee Page

The role of the CLAS Speakers Committee (CSC) is to supervise and promote the accurate and broad dissemination of results to the scientific community by talks from members of the CLAS Collaboration. This is an interface to the CSC database, containing conferences and requests for talks. After login, CSC members can use this interface to manage conferences and speaker requests.

If you would like to give a talk or show a poster:

Please log in, then revisit this page to submit your request to the CSC.

You will be able to trace the status of your request in the section below.
