Examining the Predictive Validity of Gre Scores on Doctoral Education: Students' Success and Methodology Choices in the Dissertation Process

This study examines how GRE scores can be used to better understand Education doctoral candidates\u27 methodology choices for the dissertation as well as their persistence behaviors. Candidates\u27 of one online doctoral education program were examined. Results of a MANOVA suggested that there is no difference in GRE scores based on doctoral candidates\u27 choice of methodology. Although GRE scores did not differ based on methodology choice, results of the regression analysis indicated that the linear combination of candidates\u27 verbal reasoning scores, quantitative reasoning scores, writing scores, and methodology choices accounted for significant variability in the number of semesters it took for them to complete their dissertations. The GRE writing score and methodology choice were the strongest predictors of time to completion

CHARGED KAON PRODUCTION IN TAU-DECAYS AT LEP

Kaon production in one prong tau decays has been studied using data collected with the DELPHI detector at the LEP collider. Charged kaons were identified over a large momentum range by the DELPHI barrel Ring Imaging Cherenkov detector. The following branching ratios have been determined: BR(tau –> Knu(T)) = (0.85 +/- 0.18) %, BR(tau –> Knu(tau) greater-than-or-equal-to 0 neutrals) = (1.54 +/- 0.24) %, BR(tau –> Knu(tau) greater-than-or-equal-to 1 neutrals) = (0.69 +/- 0.25) %. The result for the exclusive branching ratio is consistent with the Standard Model prediction based on tau - mu - e universality. In addition, tau decay into K*- was studied in the channel K*- –> K- pi0. The result BR(tau –> K*-nu(tau)) x BR(K*- –> K- pi0) = (0.57 +/- 0.23)% was obtained
