That’s Not Who I Am! Investigating the Role of Uniqueness and Belongingness for Designing Successful Personalized Recommendations

Although many firms rely on personalization to enhance the user experience of their digital service, their efforts might backfire if users feel misunderstood by the personalized offerings. So far, the psychological processes underlying the phenomenon of feeling misunderstood by personalization systems and potential means to alleviate this perception remain largely uninvestigated. Building on the psychological concepts of uniqueness and belongingness, we propose a framework to investigate how transparency impacts users’ feeling of being misunderstood by personalization systems. To test our research model, we conduct an online experiment using Spotify’s “Discover Weekly” playlist. The results show that considering not only users’ uniqueness but especially their belongingness is decisive to avoid misunderstanding. Further, we find that transparent explanations of the system’s inner workings elicit a feeling of control among users, which fosters the perception that both users’ uniqueness and belongingness are considered, resulting in less misunderstanding and continued usage

Selective Synthesis and Derivatization of Germasilicon Hydrides

Mixed Si/Ge hydrides Si_<i>x</i>Ge_<i>y</i>H_<i>z</i> are valuable precursors for the deposition of binary Si–Ge alloys. This work describes the synthesis and full characterization of the previously unknown germaisotetrasilane Ph₃GeSi­(SiH₃)₃ (<b>2</b>) on a multigram scale from the reaction of the lithium silanide LiSi­(SiH₃)₃ with Ph₃GeCl. The stability of the Si–Ge bond in <b>2</b> versus electrophiles and nucleophiles has been investigated with the primary aim of developing new approaches to mixed sila-H-germanes (H₃Ge)_<i>x</i>Si­(SiH₃)_4–<i>x</i>. With 1 equiv of MeLi, <b>2</b> reacted cleanly under cleavage of one Si–Si bond to give Ph₃GeSi­(SiH₃)₂Li, which is a valuable synthon for further derivatization. In contrast, the dephenylation reaction of <b>2</b> with 1 or 2 equiv of CF₃SO₃H/<i>i</i>Bu₂AlH proceeded much less selectively and afforded the desired Ph/H-germasilanes Ph₂HGeSi­(SiH₃)₃ and PhH₂GeSi­(SiH₃)₃ along with considerable amounts of Si–Ge scission products

Applications and reactivity trends of homoleptic p-block metal amido reagents

This review aims to develop an understanding of reactivity trends of p-block metal bases M(NR2)n (M = Sn: n = 2; M = Al, Ga, As, Sb: n = 3) towards organic substrates EHy containing one or more E–H bonds (E = B, N, P, S). These compounds not only act as good bases for the deprotonation of E–H bonds but recent advances in p-block amido chemistry have shown that, in addition, they can effect the dehydrogenic homo-coupling of primary phosphines and amines to give E–E bonded products. They have also been found to be active in stoichiometric and catalytic dehydrocoupling of amine-boranes, which has direct applications in hydrogen storage devices, revealing that these p-block catalysts offer potential alternatives to the extensive range of expensive and often highly toxic heavy metal catalysts. This perspective analyses three distinct reactivity patterns of p-block metal bases; deprotonation, stoichiometric dehydrocoupling and catalytic dehydrocoupling and attempts to rationalise reactivity in relation to the redox stability of the p-block metal
