   The jackknife is a reliable tool for reducing the bias of a wide range of estimators. This note demonstrates that even such versatile tools have regularity conditions that can be violated even in relatively simple cases, and that caution needs to be exercised in their use. In particular, we show that the jackknife does not provide the expected reliability for bias-reduction for the sample median, because of subtle changes in behavior of the sample median as one moves between even and odd sample sizes. These considerations arose out of class discussions in a MS-level nonparametrics course.

4. The Fear of Personal Death and the Willingness to Commit to Organ Donation

   In three studies, with samples from different countries (the United States and Israel) and religions (Christians and Jews), we found that individual levels of fear of death significantly predicted lower willingness to register as organ donors (Studies 1 and 2). Moreover, after being asked about their organ donation status (i.e., whether they are registered as donors), fear of death significantly increased among unregistered people. This did not occur among registered people, who had already faced the decision to become donors in the past (Study 2). Finally, providing non-registered (non-religious) people with a defense strategy to manage their fear of death increased their willingness to sign an organ donation commitment, partially by increasing their feelings of hopefulness. The implications of these findings for increasing organ donation registration are discussed.

   Abstract The enormous sequence heterogeneity of telomerase RNA (TR) subunits has thus far complicated their characterization in a wider phylogenetic range. Our recent finding that land plant TRs are, similarly to known ciliate TRs, transcribed by RNA polymerase III and under the control of the type-3 promoter, allowed us to design a novel strategy to characterize TRs in early diverging Viridiplantae taxa, as well as in ciliates and other Diaphoretickes lineages. Starting with the characterization of the upstream sequence element of the type 3 promoter that is conserved in a number of small nuclear RNAs, and the expected minimum TR template region as search features, we identified candidate TRs in selected Diaphoretickes genomes. Homologous TRs were then used to build covariance models to identify TRs in more distant species. Transcripts of the identified TRs were confirmed by transcriptomic data, RT-PCR and Northern hybridization. A templating role for one of our candidates was validated in Physcomitrium patens. Analysis of secondary structure demonstrated a deep conservation of motifs (pseudoknot and template boundary element) observed in all published TRs. These results elucidate the evolution of the earliest eukaryotic TRs, linking the common origin of TRs across Diaphoretickes, and underlying evolutionary transitions in telomere repeats.
