Image-based meta- and mega-analysis (IBMMA): A unified framework for large-scale, multi-site, neuroimaging data analysis
No full textThe increasing scale and complexity of neuroimaging datasets aggregated from multiple study sites present substantial analytic challenges, as existing statistical analysis tools struggle to handle missing voxel-data, suffer from limited computational speed and inefficient memory allocation, and are restricted in the types of statistical designs they are able to model. We introduce Image-Based Meta- & Mega-Analysis (IBMMA), a novel software package implemented in R and Python that provides a unified framework for analyzing diverse neuroimaging features, efficiently handles large-scale datasets through parallel processing, offers flexible statistical modeling options, and properly manages missing voxel-data commonly encountered in multi-site studies. IBMMA successfully analyzed a large-n dataset of several thousand participants and revealed findings in brain regions that some traditional software overlooked due to missing voxel-data resulting in gaps in brain coverage. IBMMA has the potential to accelerate discoveries in neuroscience and enhance the clinical utility of neuroimaging findings
Time and Flesh: Exploring the Embodied Experiences of Black Mothers
No full textDrawing on Black feminist theories of intersectionality and concepts of temporality and embodiment, this study centers Black girlhood to understand Black girls embodied journeys of “becoming” Black women. Findings revealed that: (a) Black girls often have complicated histories that lead to constrained and liberatory choices in adulthood and motherhood; (b) becoming a Black woman involves continual adaptations to temporal and historical contexts; and (c) Black motherhood is a contested space, deeply shaped by remembering Black girlhood and navigating maternal responses to legacies of harm. This study highlights the challenges and strengths in the transitory states of Black womanhood
Embodied Empowerment: Somatic Approaches to Gender Violence and Trauma
No full textThis special issue brings together recent research on embodiment and practitioner-based somatic approaches to examine trauma and healing from violence. Contributors address the long-term somatic impact of oppression and the effects of structural inequalities enacted and perpetuated through bodies and in interaction with other bodies. Somatic practices and embodiment are addressed through the lens of intergenerational trauma, gendered, racialized, political, and colonial violence, and interpersonal and collective trauma. The introductory article contextualizes embodied empowerment, collective healing, and activist-research possibilities
