ABSTRACT
Child sexual abuse (CSA) is a concern given its prevalence and harmful consequences such as depression, anxiety, substance misuse, and low academic performance, which pose great threats to children's sustainable development. In response, teachers must be empowered to play crucial roles in preventing CSA and intervening to avert CSA-related harm. We therefore explored the potential for online teacher training to improve teachers' preventive outcomes of CSA (awareness, commitment, and confidence in reporting) and student outcomes (CSA knowledge and ability to recognize, refuse, and report CSA). To assess the immediate effect of online teaching training, we analyzed pre-and post-test data from the implementation of the Second Step Child Protection Unit (CPU) on 131 teachers and 2,172 students using a multilevel structural equation modeling approach. We found a significant direct effect of online teacher training on improving teachers' preventive outcomes. Furthermore, we detected a significant indirect effect of online teacher training on children's preventive outcomes of CSA knowledge and ability to recognize, refuse, and report CSA via teachers' preventive outcomes of CSA awareness.
ABSTRACT
We investigated the longitudinal effects of the Second Step Child Protection Unit (CPU; Committee for Children) on student outcomes through a randomized controlled trial. Eight schools with a total sample including 2,031 students were assigned randomly to the CPU intervention or the wait-list control condition. We employed a multi-process latent growth model using a structural equation modeling framework which simultaneously analyzed student outcome growth via the effects of the intervention. The moderating effect of gender was also included. Over four data collection waves (pretest, posttest, follow-up [6 months] and follow-up [12-months]), the intervention group students were better able to recognize appropriate requests in CSA scenarios than control group students over time. Teacher-student relations improved for the students in the intervention schools but worsened for the students in the control schools over time. Despite concerns that CSA prevention programs may result in the unintended consequence of making children more fearful, children in both conditions did not show increased fears over time. The longitudinal effect on CSA recognition was more pronounced among girls, who suffer from higher CSA prevalence, compared with boys. Implications for prevention, policy, and directions for future research are discussed.

Background: Recent research indicates that pregnant women in rural communities are at increased risk of experiencing IPV and comorbid illicit opioid use compared to urban-residing pregnant women. Few studies of the interactions among rurality, substance use, and victimization in pregnant women exist. The current study sought to examine the relationship between IPV and opioid use and the interaction effects of rurality in Appalachian pregnant women. Methods: A convenience sample of pregnant women who were enrolled in a smoking cessation research study was used for this analysis. Participants included 488 pregnant women from five prenatal clinics in South-Central Appalachia. Data were from self-reported assessments and semi-structured interviews on substance use and IPV conducted from first trimester of pregnancy through eight months postpartum. Results: Four hundred and ten participants reported experiencing any form of IPV in the past year. Logistic regression results indicated that physical IPV was associated with opioid use, but sexual and psychological IPV were not. The moderation model indicated direct effects between IPV and opioid use, but were not moderated by rurality. Conclusion: This study suggests a need to further understand the relationship between substance use, IPV, and rurality in pregnant women. The specific subtopic of opioid use by pregnant women living in rural communities, and its relationship to IPV victimization and adverse fetal and maternal health outcomes, continues to be an understudied, but critically important area. Limitations and future directions pertaining to IPV screenings and interventions for pregnant women are discussed.

Despite 35 years of study, burnout researchers have failed to reach a consensus about whether burnout is distinct from depression. This review compiled reports containing zero-order correlations between scores on burnout, depression, and other measures of negative affect (NA) based on (a) reviews published by Kahill (1988), Glass and McKnight (1996), and Bianchi et al. (2015b), and (b) a search of PsycInfo using "depression" and "burnout" as search terms to find relevant studies published after 2014. The resulting data set contained 69 studies with 196 burnout-depression correlations based on 46,191 participants. We found an overall effect size of .492 between scores on burnout and depression measures (essentially equivalent to the .52 value reported in Koutsimani et al.'s, 2019, review) and an effect size of .546 between the Maslach Burnout Inventory emotional exhaustion scale and depression. Similarly, a correlation of .53 between burnout and NA measures is similar in size to the .46 correlation found by Koutsimani et al. Moderator analyses indicated that a larger burnout-depression correlation was associated with a higher proportion of female participants in a study, older participants, participants who had worked longer, and burnout measures with higher reliability estimates. The effects of age and years employed on the burnout-depression relationship suggest that repeated and negative work experiences are required for burnout to develop to the extent that its effects overlap with symptoms of depression. Conceptualizing the empirical relation between burnout and depression as a single point estimate may miss the more complex empirical picture.

We previously identified a cluster of yield-related quantitative trait loci (QTLs) including plant height in CR4379, a near-isogenic line from a cross between Oryza sativa spp. japonica cultivar 'Hwaseong' and the wild relative Oryza rufipogon. Map-based cloning and transgenic approaches revealed that APX9, which encodes an l-ascorbate peroxidase 4, is associated with this cluster. A 3 bp InDel was observed leading to the addition of a valine in Hwaseong compared with O. rufipogon. APX9-overexpressing transgenic plants in the Hwaseong background were taller than Hwaseong. Consistent with these results, APX9 T-DNA insertion mutants in the japonica cultivar Dongjin were shorter. These results confirm that APX9 is the causal gene for the QTL cluster. Sequence analysis of APX9 from 303 rice accessions revealed that the 3 bp InDel clearly differentiates japonica (APX9HS) and O. rufipogon (APX9OR) alleles. indica accessions shared both alleles, suggesting that APX9HS was introgressed into indica followed by crossing. The finding that O. rufipogon accessions with different origins carry APX9OR suggests that the 3 bp insertion was specifically selected in japonica during its domestication. Our findings demonstrate that APX9 acts as a major regulator of plant development by controlling a valuable suite of agronomically important traits in rice.

Teachers play a critical role in child sexual abuse (CSA) prevention and intervention efforts. We examined the impact of the Second Step Child Protection Unit (CPU) on improving teacher awareness, attitudes, and teacher-student relations for 161 teachers. Teacher baseline scores and treatment acceptability were examined as moderators. Structural equation modeling (SEM) revealed a significant effect of the CPU on teachers' awareness, attitudes, and teacher-student relations, particularly for teachers with lower prior knowledge, attitudes, and student relationships. Teachers' acceptability of the CPU also moderated outcomes, where a higher level of acceptability of CSA interventions was associated with an increase in outcomes.

A quantitative trait locus (QTL) gw8.1 was detected in the population derived from a cross between the elite japonica cultivar, 'Hwaseong' and Oryza rufipogon (IRGC 105491). Near isogenic lines (NILs) harboring the O. rufipogon segment on chromosome 8 showed increased grain length and weight compared to those of the recurrent parent, Hwaseong. This QTL was mapped to a 175.3-kb region containing 28 genes, of which four were considered as candidates based on the presence of mutations in their coding regions and as per the RNA expression pattern during the inflorescence stage. Leaves and panicles obtained from plants harvested 5 days after heading showed differences in gene expression between Hwaseong and gw8.1-NILs. Most genes were upregulated in O. rufipogon and gw8.1-NIL than in Hwaseong. Scanning electron microscopy analysis of the lemma inner epidermal cells indicated that cell length was higher in gw8.1 NIL than in Hwaseong, indicating that gw8.1 might regulate cell elongation. Among the candidate genes, LOC_Os08g34380 encoding a putative receptor-like kinase and LOC_Os08g34550 encoding putative RING-H2 finger protein were considered as possible candidates based on their functional similarity.

AIMS: This article is a report on a study of the multidimensional predictors of caregiver burden in caregivers of individuals with dementia using nationally representative data. BACKGROUND: Caregiver burden affects the health of both caregivers and their care-recipients. Although previous studies identified various predictors of caregiver burden, these predictors have not been confirmed in nationally representative population. METHODS: Data for this secondary analysis was provided by the National Alliance for Caregiving, American Association of Retired Persons. The data were collected through a telephone survey of randomly selected adults in seven states in 2003 (weight adjusted n = 302). Descriptive statistics, inter-correlation analysis and a hierarchical multiple regression analysis were performed. RESULTS/FINDINGS: Disease-related factors were the most significant predictors, explaining 16% of caregiver burden; these were followed by caregiver socio-demographical factors and caregiving-related factors (F = 21·28, P < 0·01). Significant individual predictors were impairment of activities of daily living or instrumental activities of daily living, the number of hours of caregiving, use of coping strategies, co-residence, spousal status and caregiver gender (P < 0·05). CONCLUSION: Impaired function in care-recipients predicts caregiver burden, and also interacts with demographical- and caregiving-related factors. Thus, it will be beneficial to both care-recipients and caregivers to target nursing interventions and community services to improve the functional abilities of individuals with dementia.

Sediment samples were collected from seven locations of the MeeHo stream in Cheongju city, strained out by a sieve, dried by an oven and pulverized by an agate mortar. Instrumental neutron activation analysis (INAA) was applied for the determination of the elemental contents in the sediment samples by using the NAA #1 and #2 irradiation holes of the HANARO research reactor and HPGe gamma-ray spectrometers. Twenty-five elements were determined by a relative method with NIST SRM 2711-Montan Soil and the ranges of the elemental contents for the seven locations were identified. The contamination levels for elements such as As, Ba, Cr, Mn, Fe and Zn were compared with the guidelines of USEPA. The detection limits and combined uncertainties for the hazardous elements such as As, Ba, Cr, Mn, Sb, V and Zn were estimated under the given analytical conditions.
