High-resolution sea surface reconstructions off Cape Hatteras over the last 10 ka

International audienceThis study presents high-resolution foraminiferal-based sea surface temperature, sea surface salinity and upper water column stratification reconstructions off Cape Hatteras, a region sensitive to atmospheric and thermohaline circulation changes associated with the Gulf Stream. We focus on the last 10,000 years (10 ka) to study the surface hydrology changes under our current climate conditions and discuss the centennial to millennial time scale variability. We observed opposite evolutions between the conditions off Cape Hatteras and those south of Iceland, known today for the North Atlantic Oscillation pattern. We interpret the temperature and salinity changes in both regions as co-variation of activities of the subtropical and subpolar gyres. Around 8.3 ka and 5.2-3.5 ka, positive salinity anomalies are reconstructed off Cape Hatteras. We demonstrate, for the 5.2-3.5 ka period, that the salinity increase was caused by the cessation of the low salinity surface flow coming from the north. A northward displacement of the Gulf Stream, blocking the southbound low-salinity flow, concomitant to a reduced Meridional Overturning Circulation is the most likely scenario. Finally, wavelet transform analysis revealed a 1000-year period pacing the δ18O signal over the early Holocene. This 1000-year frequency band is significantly coherent with the 1000-year frequency band of Total Solar Irradiance (TSI) between 9.5 ka and 7 ka and both signals are in phase over the rest of the studied period

“If She’s Sad, I’m Sad Too” Emotional Closeness Between French Grandparents and Emerging Adult Grandchildren: Between Emotional Bonding and Emotional Worries

International audienceThe present study examines emotional closeness between French grandparents and their emerging adult grandchildren. The present study explores facets of the grandparent-grandchild relationship that have not been extensively investigated. It highlights the importance of the grandchildren's relationship with their grandparents as they reach adulthood and the facets of intergenerational emotional closeness during this period of transition. Semi-structured interviews were conducted individually with 13 grandparents and their emerging adult grandchildren. Four themes were extracted from the thematic analysis of the interviews (emotional bonding; sharing identity, values, and personality; emotional worries and concerns about illness and death; adult role acquisition). The study reveals the depth of the grandparent-emerging adult-grandchild relationship, which is a source not only of love, support, and companionship in their daily life, but also of worries about the future. This study also identifies some hitherto unexplored facets that demonstrate the complexity of this relationship as grandchildren become adults

Comparing U.S. and French grandparent-grandchild relationships

International audienceIn response to the many calls for the advancement of cross-cultural communication research, we compared U.S. and French grandchildren’s received grandparental affection and perceptions of their grandparents as ideal (i.e., grandparent attributes and behaviors that grandchildren believe characterize a desirable grandparent). A total of 456 young adult grandchildren from the U.S. (n = 171) and France (n = 285) completed the Grandchildren’s Received Affection Scale (GRAS) and the Ideal Grandparent Scale (IGS) in reference to their relationships with a specific grandparent. Results of a MANOVA and an independent samples t-test indicated that, compared to French grandchildren, U.S. grandchildren scored higher on both the GRAS and the IGS. These findings are discussed in reference to how these differences may impact grandchildren and grandparent
