T metrics resulting from the 20 block allocation exercise.

 Variable Description H number of blocks in the horizontal dimension of the T V number of blocks in the vertical dimension of the T HV aspect ratio of the T. Measured by dividing H by V. HV > 1 trends toward multidisciplinarity; HV < 1 trends toward a single disciplinary focus ΔHV change in the future aspect ratio relative to the present (ΔHV = HVfuture/HVpresent). ΔHV > 1 indicates a change toward increasing multidisciplinarity. ΔHV < 1 indicates a change toward greater disciplinarity.

Patterns in T profiles among Coastal Institute IGERT Project students. Values presented are means and standard errors (in parentheses). Variable names are given in Table 1. The t-tests were used to determine if group means were the same. One-sample t-tests were used to determine if HV values were significantly different from 1 (equal commitment to disciplinary and multidisciplinary research). The F-max test was used to test if group variances were equal. “Future” refers to 5 to 10 years post-doctorate.
