Clarifying the generic limits of Talbotiella and Hymenostegia (Detarieae, Caesalpinioideae, Leguminosae)

The formal description of four species of Cameroonian forest legume trees new to science has been hampered by uncertainty as to whether their correct generic placement is within Hymenostegia Harms or Talbotiella Baker f. As there has been doubt as to whether these two genera differ from one another, an investigation was undertaken so that the new species could be correctly assigned to genus. Using morphological, molecular and pollen data, our study supports the recognition of Hymenostegia and Talbotiella as distinct genera, consequently the new species are correctly placed in Talbotiella. In addition, our data reveal the extensive heterogeneous nature of Hymenostegia as currently circumscribed and the need to transfer H. breteleri to Talbotiella

Differences in the 1-Year Persistence Rates of International Students by Their Institutional Status at Texas Community Colleges: A Statewide, Multiyear Investigation

In this multiyear, statewide study, the degree to which 1-year persistence rates differed by the institutional status (i.e., stayed or transferred) of International students who were enrolled in Texas community colleges was determined.  Inferential statistical procedures revealed the presence of statistically significant differences in 1-year persistence rates between International students who stayed at the same Texas community college and International students who transferred to a different Texas community college.  In all cases, the 1-year persistence rates of International students who stayed were higher, 14 to 52 times higher, than the 1-year persistence rate of International students who transferred.  In all 15 academic years (i.e., 1999-2000 through 2013-2014), very large effect sizes were present. &nbsp
