Farrington and colleagues developed a model that contends that academic mindsets, academic perseverance, learning strategies, social skills, and academic behaviors affect academic success. This study tests a modified version of this model with first-year students (n ¼ 1,603) at a large, ethnically diverse, urban university. The hypothesized structural model had acceptable fit, with minor modifications. The direct effect on academic performance of academic mindset was strong, of academic perseverance was modest, and of time management was nonsignificant. Only participants' academic performance had a strong positive effect on retention. Few differences by ethnicity were found. As mindsets are amenable to change, with intervention programs showing promising effects, students with low scores should be targeted to receive support early in their college careers so they may succeed in college.

The chemistry of the ligand (R 2 PCH 2 SiMe 2 ) 2 N À (R ¼ cyclohexyl and t Bu), '' PNP-R '', on ruthenium is developed, including RuH(PNP-Cy)(PPh 3 ) and (HPNP-R)RuH 3 Cl. The latter contains a protonated nitrogen (i.e., amine as a donor to Ru) and one H 2 ligand (X-ray structure for R ¼ t Bu). This compound can be dehydrohalogenated to give (PNP-Cy)RuH 3 , which undergoes H/D exchange of D 2 into its cyclohexyl rings, and is itself dehydrogenated by excess H 2 C=CHR to give [Cy 2 PCH 2 SiMe 2 NSiMe 2 CH 2 PCy(C 6 H 8 )] Ru, which contains a triply dehydrogenated cyclohexyl ring p-allyl bonded to Ru. (PNP-Cy)RuH 3 reacts with dihydrofurans to give the heteroatom-stabilized carbene complex (PNP-Cy)RuH[=CO(CH 2 ) 3 ].The many pincer ligands I that have been reported recently 1-10 fall into two general categories, those with a neutral donor G (e.g., pyridine-based), and those with an anionic donor G (e.g., phenyl-based). The neutral donor D o can be phosphorous or nitrogen, and this D o RR 0 group can have controllable electronic and steric (including chiral) features, leading to a versatile set of pincer ligands. 5,11,12 Depending on the nature of the '' arm '' that links G to D o , the donor can be at the amine or imine oxidation level. We have been attracted to the pincer ligands II pioneered by Fryzuk because the group G is anionic and, unlike phenyl, bears a lone pair. 13 Scheme 1

The author was inspired to write this article in light of the ongoing and recent claims by some radical feminists that trans women are not women. This is much more than a debate among differing theoretical positions. Women have been threatened, both trans* and cis women. The vitriol on both sides is alarming and undermining of the feminism we all share. Rather than write an academic, philosophical treatise on the meaning of "woman," the author wrote this from her firstperson experience, as someone who was "born female" and identifies as a woman but is often socially read as trans* (a trans man). The author aims to articulate a radical feminist understanding of women that shows trans women are women in concrete, personal terms.
