The value of experts by experience within the field of intellectual disabilities is receiving greater recognition. This study explored the experiences of peer trainers regarding the impact of being a (1) trainee in a train the trainer course (n = 9), and (2) peer trainer in a Dutch training course (n = 6) aimed towards the self‐growth of people with intellectual disabilities. In addition to examining the experiences of peer trainers themselves, we investigated the perspective of coaches (n = 4) regarding the experiences of peer trainers. Peer trainers and coaches were questioned using individual and group interviews. Data were analysed using thematic analysis. Three themes were identified: (1) Growing and flourishing, (2) Performing a meaningful role for your peer and (3) Experiencing reciprocity and a sense of belonging. Working as a peer trainer was valuable and produced several benefits, ranging from increased self‐confidence to feelings of belonging and reciprocity. [ABSTRACT FROM AUTHOR]

Research on the impact of ex‐romantic partners on current romantic relationships is mainly focused on negative aspects. Here instead we focus on the potential positive influence of reflecting on nostalgic memories of one's ex‐partner. In three studies, we found that reflecting on nostalgic memories of one's ex‐partner increased the perception of current relationship quality (Studies 1– 3) and approach motivation towards the current relationship (Study 3), compared to a control condition. We also tested a potential underlying mechanism—perception of self‐growth. We found that perception of self‐growth mediated the positive effects of reflecting on nostalgic memories about an ex‐partner on perceived current relationship quality (Studies 2 and 3) and approach motivation in the current relationship (Study 3). Implications for research and therapy are discussed. [ABSTRACT FROM AUTHOR]

The in situ self‐catalyzed growth of manganese‐embedded 3D flakes‐coated carbon rods (GFC) as an efficient oxygen‐reduction reaction (ORR) catalyst of Zinc‐air batteries is described for the first time. By optimizing the amount of Mn in the precursor, a series of 3D graphene‐like flakes‐coated carbon rods were synthesized. GFC with a doping amount of Mn of 10 % (GFC‐10) exhibits excellent ORR performance with an onset potential of 0.94 V (vs. reversible hydrogen electrode). The Zinc‐air battery is constructed with GFC‐10 as the cathode catalyst, and it exhibits a peak power density of 128.9 mW cm−2 and a cycling stability of 75 h at a current density of 10 mA cm−2, which are superior to the commercial 20 wt% Pt/C‐based Zinc‐air battery. Interestingly, the introduction of Mn facilitates the self‐catalyzed growth of carbon rods, and the change of Mn amount can effectively regulate the morphology of materials. The improved ORR performance of the catalyst is ascribed to the synergistic effect of unique hierarchical porous structure, high‐charge transport capacity, abundant carbon defects/edges and Mn‐Nx sites. This research provides a new avenue to fabricating highly active Mn‐based electrocatalysts for renewable energy systems. [ABSTRACT FROM AUTHOR]
