Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply
No full textThis reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.
Salix neowilsonii W. P. Fang 1948
No full textSalix neowilsonii W.P.Fang (1948: 313). Type:— CHINA. Sichuan [Szechuan]: Chengdu [Chengtu], Jing Ju Si [Tsing Chu Ssu], 15 March 1945, W. P. Fang 19403 (holotype SZ00516909; isotype IBK00078135). One of the paratypes: CHINA. Sichuan: Chengdu, Wang Jiang Lou [Wang-Kiang-lau], 15 March 1947, W. P . Fang 19616 (CQNM0020750, SZ00051523). Note:—In the protologue (Fang 1948), W. P. Fang 19403 was designated as the type without specifying the herbarium. Two duplicates were traced at PE and SZ, only the duplicate at SZ (00516909) where W. P. Fang worked at that time bears the handwritten annotation determined by W. P. Fang. It may be single specimen used by Fang when he preparing the protologue for the name and might be therefore considered as the holotype according to Art. 9.1 (Turland et al. 2018). Both duplicates do not bear the information of the locality of “Tsing Chun Ssu” (probably Jing Ju Si in east of former Chengdu downtown). The gathering W . P. Fang 19616 is one of 27 paratypes cited in the protologue, another duplicate of which is deposited at SZ.Published as part of Chen, Feng & He, Hai, 2022, The historical relics in Chongqing Natural History Museum: An annotated checklist of original materials for 37 names of Chinese seed plants, pp. 38-52 in Phytotaxa 530 (1) on pages 45-46, DOI: 10.11646/phytotaxa.530.1.3, http://zenodo.org/record/582393

It is informed that the duplicates at SZ are more complete and in better condition to identify this species. Because we did not examine the specimens there, we do not designate the lectotype for the name.</p>Published as part of <i>Chen, Feng & He, Hai, 2022, The historical relics in Chongqing Natural History Museum: An annotated checklist of original materials for 37 names of Chinese seed plants, pp. 38-52 in Phytotaxa 530 (1)</i> on pages 47-48, DOI: 10.11646/phytotaxa.530.1.3, <a href="http://zenodo.org/record/5823939">http://zenodo.org/record/5823939</a>
