Sub-Saharan African Women’S Experiences Of Social Support During Childbirth In Finland, Emma Kwegyir-Afful, Anita Wikberg

International Nursing Research Congress (INRC)

Background: Over 50% of the estimated 90 million international migrants in Europe are women, many of whom are of childbearing age (Fair et al., 2020). Poorer pregnancy and birth outcomes are common among ethnic minority women (Soltani et al., 2020). In Finland Sub-Saharan African women (SSAW) are more likely to undergo caesarean section than Finnish women (Bastola et al., 2020).

Social support which is both informational (providing information for problem-solving) and emotional (offering care and/or trust) is key social determinant of health. It can be acquired through informal networks such as friends, family, and ethnic communities or through formal networks …

Study The Effects Of Nuclear Correlations And Tensor Forces On The Nuclear Structure Of The 10B Nucleus, Farah Faris Kaddoori

Baghdad Science Journal

A detailed theoretical investigation of nuclear transition charge densities is carried out for the odd–odd nucleus ¹⁰B, with particular emphasis on collective dynamics and short-range nucleon–nucleon correlations. Longitudinal C2 form factors for inelastic electron scattering are evaluated for several excited nuclear states. The transition charge density is expressed as a superposition of the shell-model contribution and a core-polarization term arising from collective nuclear dynamics. The latter is evaluated within the Tassie collective model using correlated ground-state two-body charge-density distributions (2BCDDs). These correlated densities are derived using the nuclear contact formalism, incorporating short-range central correlations and tensor-force effects from realistic …

Development And Validation Of The Art Engagement Reflection Scale, Rebekah M. Rodriguez-Boerwinkle, Zorana Ivcevic, Pablo P.L. Tinio

Department of Educational Foundations Scholarship and Creative Works

Aesthetic encounters often feel immediate, yet contemporary theories emphasize that engagement with art unfolds over time through a sequence of perceptual and cognitive processes. Despite the importance of this temporal structure to models of aesthetic experience, there are no psychometric tools designed to capture engagement as a process rather than as a disposition or an outcome. We introduce the Art Engagement Reflection Scale (AERS), a brief, mixed-methods, artwork-specific measure grounded in the mirror model of art. We present two studies that examined the psychometric properties of the AERS across controlled and naturalistic online contexts. In Study 1, participants responded to …

Construction And Application Of Clinical Evidence Framework For Brain-Computer Interface, Wenxiu Qi, Cheng Zhou

Bulletin of Chinese Academy of Sciences (Chinese Version)

Brain-computer interface systems are emerging neurotechnologies that are gradually moving from laboratory research toward clinical application. However, their inherent features, including small sample sizes, heterogeneous technical pathways, and rapid product iteration, make it difficult to integrate safety and efficacy data across studies or to conduct meaningful cross-study comparisons. These challenges not only hinder the cumulative development of evidence in evidence-based medicine, but also complicate the assessment of clinical access and regulatory review. In addition, subjective evidence, such as patient experience, remains insufficiently captured in existing evaluation frameworks. It is therefore necessary to examine the structure of evidence for brain-computer interface …
