Only 1 study-level moderator (sex of first author) was significant after adjusting for other moderators. The small effect size and primarily nonsignificant results for main effects of early

maternal employment should allay concerns about mothers working when children are young. However, negative findings associated with employment during the child’s first year are compatible with calls for more generous maternal leave policies. Results highlight the importance of social context for identifying under which conditions WZB117 chemical structure and for which subgroups early maternal employment is associated with positive or negative child outcomes.”
“Model order selection in group independent component analysis (ICA) has a significant effect on the obtained components. This study investigated the reproducible brain regions of abnormal default-mode network (DMN) functional connectivity related with cocaine addiction through

different model order settings in group ICA. Resting-state fMRI data from 24 cocaine addicts and 24 healthy controls were temporally concatenated and processed by group ICA using model orders of 10, 20, 30, 40, and 50, respectively. For each model order, the group ICA approach was repeated 100 times using the ICASSO toolbox and after clustering the obtained components, centrotype-based anterior and posterior DMN components were selected for further analysis. Individual DMN components Fedratinib mw were obtained through back-reconstruction and converted to z-score maps. A whole brain Sotrastaurin mixed effects factorial ANOVA was performed to explore the differences in resting-state DMN functional connectivity between cocaine addicts and healthy controls. The hippocampus, which showed decreased functional connectivity in cocaine addicts for all the tested model

orders, might be considered as a reproducible abnormal region in DMN associated with cocaine addiction. This finding suggests that using group ICA to examine the functional connectivity of the hippocampus in the resting-state DMN may provide an additional insight potentially relevant for cocaine-related diagnoses and treatments.

“In Arab countries, the proportion of older adults is rapidly increasing, highlighting the need to conduct research on factors that influence aging. We describe the context-specific challenges faced and the solutions negotiated during the conduct of a survey study on family relations and aging in Greater Beirut, Lebanon.

Drawing on the experience of a recently completed survey study, we reflect on the context-specific challenges faced and the solutions negotiated during the phases of questionnaire construction, interviewer training, sampling, and participant recruitment as a means to contribute to the growing area of cross-cultural survey research.
