<p>Shina:</p>
<p>Often, but not always, the "flagship" (most prestigious, often largest) campus of a state university is referred to simply by the name of the state.</p>
<p>So . . . </p>
<p>University of Texas - Austin = Texas
UC Berkeley = California, or Cal
University of Michigan = Michigan
University of Illinois (Urbana-Champain) = Illinois
University of North Carolina (Chapel Hill) = Carolina, or North Carolina</p>
<p>etc.</p>
<p>Other institutions within the same state university system will be called something else:</p>
<p>UTEP, Texas A&M
UCLA, UCSB, UC Davis
Michigan State
Illinois-Chicago
NC State, UNC Greensboro</p>
<p>But</p>
<p>Pennsylvania State University (University Park) is not "Pennsylvania" or "Penn", since those refer to the University of Pennsylvania, a private Ivy League University that is about 100 years older. Penn State is Penn State.</p>
