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.

Silver-Based Radical Reactions: Development and Insights
No full textSilver-mediated reactions have recently emerged as a frontier area in organic chemistry. Indeed, the remarkable property of silver as a single- electron oxidant has led to its exploitment into the field of radical chemistry. The excellent reactivity and high selectivity exhibited by silver salts in the ac- tivation of different organic substrates place them among the most prominent reagents in free radical reactions. The present review aims to provide the readers with a critical overview of silver-based radi- cal reactions, especially emphasizing the reactivity, selectivity and a detailed description of the reaction mechanism with particular attention to the role of Ag(I)-based catalysts/reactants. The selected exam- ples have been classified according to the type of radicals generated, namely carbon-centered radicals and heteroatom (such as nitrogen, oxygen, phospho- rus, sulfur)-centered radicals. The generation of such radicals as well as their application in synthetic pro- cesses including oxidation, addition, coupling, and radical cascades have been described in detail
