Two-photon resonant excitation of interatomic coulombic decay in neon dimers

The recent availability of intense and ultrashort extreme ultraviolet sources opens up the possibility of investigating ultrafast electronic relaxation processes in matter in an unprecedented regime. In this work we report on the observation of two-photon excitation of interatomic Coulombic decay (ICD) in neon dimers using the tunable intense pulses delivered by the free electron laser FERMI. The unique characteristics of FERMI (narrow bandwidth, spectral stability, and tunability) allow one to resonantly excite specific ionization pathways and to observe a clear signature of the ICD mechanism in the ratio of the ion yield created by Coulomb explosion. The present experimental results are explained by ab initio electronic structure and nuclear dynamics calculations

Intergenerational Communication – an interdisciplinary mapping review of research between 1996 and 2017

Concerns have been raised regarding the limited opportunities for intergenerational communication both outside and within the family. This “mapping review” draws together empirical literature in the topic published since 1996. Three hundred and twenty-four published studies met inclusion criteria, based on abstract review. The contents of each study were subjected to thematic analysis and nine broad themes emerged. These were (1) Dynamics of relationships, (2) Health & Well-being, (3) Learning & Literacy, (4) Attitudes, (5) Culture, (6) Digital, (7) Space, (8) Professional Development, and (9) Gender & Sexual Orientation. Studies commonly intersected disciplinary research areas. There was a marked rise across three key academic journals since 2007. An emergent finding was that a third of the studies relate to programs addressing intergenerational interventions, but many of these were primarily descriptive and failed to specify a primary outcome. Review implications and future research directions are discussed

Communicative Predictors of a Shared Family Identity: Comparison of Grandchildren’s Perceptions of Family-of-Origin Grandparents and Stepgrandparents

From an intergroup perspective on family relationships, the current study investigates family-of-origin grandparents and stepgrandparents to determine similarities and differences in communication and relational dimensions. Participants (N = 88) completed questionnaires on family-of-origin grandparents and stepgrandparent relationships. From the perspective of young adult grandchildren, the research explores the role of supportive communication, reciprocal self-disclosure, nonaccommodative communication, and parental encouragement in predicting a sense of shared family identity with each grandparent type. Results are discussed in terms of implications for intergroup research, grandparent-grandchild communication, and stepfamily relationships
