Given the strong link between religiousness and hope, we sought to further understand the relations of these potentially powerful resources for youth living in adversity. Although existing research suggests that religiousness might be associated with adolescent hope via spirituality and social connections, few studies have tested models that integrate both. Thus, as applied psychologists, the aim of this paper was to test a theoretical model in the lives of youth. Drawing on a Relational Developmental Systems metatheory, we sought to further elucidate the relations between religiousness and hope and to explore how involvement in the faith-based youth-development organization, Compassion International (CI), might facilitate character strengths like hope. In order to do so, we tested whether religiousness was directly and indirectly (via spirituality and social connection) related to hopeful future expectations, using a sample of 9–15-year-olds in El Salvador (M = 11.6 years; n = 888), half of whom were involved in CI and the other half of whom were a locally matched counterfactual sample. Structural equation models revealed that higher levels of religiousness were directly and indirectly associated with higher levels of hope in relation to higher levels of spirituality and social connections among these youth. CI-supported youth reported significantly higher levels of religiousness than the counterfactual sample. Findings suggest that the relationship between religiousness and hope is best understood when it incorporates youth’s spirituality and social connections associated with religion.

Efforts to improve the achievement gap between low-income children and their more affluent peers has led to the development of classroom interventions and curricula to increase executive functioning (EF) and social-emotional skills (SE), thought to be foundational for learning. The Second Step Early Learning (SSEL) curriculum is a commercially available curriculum designed to improve school readiness by building EF and SE skills. However, although widely used, it has not been widely studied. Modeling SSEL’s underlying theory of change, structural equation modeling (SEM) was used to longitudinally examine the effects of the curriculum on low-income preschool children’s kindergarten school readiness through the hypothesized mediating role of EF and SE skills in improving pre-academic skills and task behavior in preschool. In a cluster randomized trial, 972 children attending 63 preschool classrooms within 13 low-income Head Start or community preschools were individually tested at the beginning (T1) and end of preschool (T2, n = 836) and followed into kindergarten. Children’s average age at T1 was 53 months, with 51% male, 42% Anglo-American, 26% African–American, and 40% Hispanic-American. Children’s EF, social skills, pre-literacy/language, and pre-math skills were assessed by trained child assessors blind to study conditions at T1 and T2. Assessors also rated children’s task behavior in the testing situation at T1 and T2. School records of children’s kindergarten screening scores were obtained on 345 children at T3. It was expected that SSEL would have both direct and indirect effects on kindergarten readiness through improvements in children’s SE and EF skills preschool academic skills and on-task behavior. We found no direct effects of SSEL on either pre-academic or on-task behavior outcomes in preschool, nor on later kindergarten readiness. However, SSEL significantly increased EF, and as expected by SSEL’s theory of change, growth in EF predicted gains in both pre-academics (particularly pre-math), and on-task behavior in preschool. End-of-year pre-academic skills and on task behavior in turn predicted better kindergarten readiness. Further, SE (although not impacted by SSEL) had direct and indirect effects on kindergarten readiness. Thus, overall, our findings largely support SSEL’s theory of change, particularly in relation to EF.

Assessing the status of metastasis in sentinel lymph nodes (SLNs) by pathologists is an essential task for the accurate staging of breast cancer. However, histopathological evaluation of SLNs by a pathologist is not easy and is a tedious and time-consuming task. The purpose of this study is to review a challenge competition (HeLP 2018) to develop automated solutions for the classification of metastases in hematoxylin and eosin-stained frozen tissue sections of SLNs in breast cancer patients. Materials and Methods A total of 297 digital slides were obtained from frozen SLN sections, which include postneoadjuvant cases (n=144, 48.5%) in Asan Medical Center, South Korea. The slides were divided into training, development, and validation sets. All of the imaging datasets have been manually segmented by expert pathologists. A total of 10 participants were allowed to use the Kakao challenge platform for 6 weeks with two P40 GPUs. The algorithms were assessed in terms of the area under receiver operating characteristic curve (AUC). Results The top three teams showed 0.986, 0.985, and 0.945 AUCs for the development set and 0.805, 0.776, and 0.765 AUCs for the validation set. Micrometastatic tumors, neoadjuvant systemic therapy, invasive lobular carcinoma, and histologic grade 3 were associated with lower diagnostic accuracy. Conclusion In a challenge competition, accurate deep learning algorithms have been developed, which can be helpful in making frozen diagnosis of intraoperative SLN biopsy. Whether this approach has clinical utility will require evaluation in a clinical setting.

This study examines the psychometric properties and applicability of the Measure of Diverse Adolescent Spirituality (MDAS), including the factors of transcendence and fidelity, across 2 samples of adolescent youth from low-and middle-income countries (Mexico and El Salvador). Drawing on relational developmental systems metatheory, spirituality is conceptualized as experience of and response to one's perception of transcendence. Although an increasing number of spirituality measures exist, few are theoretically predicated and developed for use with adolescents with various spiritual orientations. We present data testing the MDAS across 2 youth samples, aged 12 to 15 years, derived from previous studies conducted in Mexico (n ϭ 365; M age ϭ 13.65 years) and in El Salvador (n ϭ 220; M age ϭ 12.98 years). We confirmed the measurement structure of the MDAS and tested for between-groups measurement invariance across the two samples. Invariance was established across the Mexico and El Salvador samples, providing initial evidence regarding the usefulness and applicability of the transcendence and fidelity components of the MDAS across these samples. Implications are discussed regarding the use of a multidimensional measure of spirituality that assesses both spiritual experience and commitment among adolescents.
