The scheme of composition of the waltz seems borne of a double rotation : internal ( with vertigo , represented choreographically and experienced by the dancers ) and external ( with the circles the dancers describe ) , but the external rotation serves only to represent the external circle of the internal movement which continues to widen and whose center is situated in each of the participants ; thus the circles of the waltz are determined by the position of each dancer , by his or her point of view . F1 accepts a set of HTML documents ( the input semantics i1 ) , performs the document collection fan-out function4 ( the functional ontology f1 ) , and generates output document collection in which documents are classified by news sources ( the output semantics o1 ) . Students entering UNCG in the fall semester are expected to participate in Spartan Orientation , Advising , and Registration ( SOAR ) , which occurs in June , along with Rawkin ' Welcome Week the week prior to the beginning of fall classes in August . In addition to focusing research and teaching on issues of nonprofit management , the Center sponsored 48 nonprofit leaders in the new Executive Program for Nonprofit Leaders this summer and provides outreach through the Public Management Program , Alumni Consulting Teams ( ACT ) , and community programs .
