Filipino Mothersâ Self-Efficacy in Managing Anger and in Parenting, and Parental Rejection as Predictors of Child Delinquency
The authors tested a model in which Filipino mothersâ self-efficacy in managing anger/irritation influenced child delinquency via two parenting variables: parental self-efficacy and parental rejection. Structured interviews were conducted with 99 mothers twice with an interval of one year with efficacy beliefs and rejection measured in the first year and child delinquency data collected in the following year. Path analyses showed that self-efficacy in managing anger/irritation negatively predicted child delinquency indirectly through the sequential mediation of parental selfefficacy and parental rejection. Results provided further evidence for the importance of efficacy beliefs, particularly self-efficacy in managing anger/irritation and parental self-efficacy, in the domain of child development
High-speed multicolor microscopy of repeating dynamic processes
Images of multiply labeled fluorescent samples provide unique insights into the localization of molecules, cells, and tissues. The ability to image multiple channels simultaneously at high speed without cross talk is limited to a few colors and requires dedicated multichannel or multispectral detection procedures. Simpler microscopes, in which each color is imaged sequentially, produce a much lower frame rate. Here, we describe a technique to image, at high frame rate, multiply labeled samples that have a repeating motion. We capture images in a single channel at a time over one full occurrence of the motion then repeat acquisition for other channels over subsequent occurrences. We finally build a high-speed multichannel image sequence by combining the images after applying a normalized mutual information-based time registration procedure. We show that this technique is amenable to image the beating heart of a double-labeled embryonic quail in three channels (brightfield, yellow, and mCherry fluorescent proteins) using a fluorescence wide-field microscope equipped with a single monochrome camera and without fast channel switching optics. We experimentally evaluate the accuracy of our method on image series from a two-channel confocal microscope

A transgenic quail model that enables dynamic imaging of amniote embryogenesis
Embryogenesis is the coordinated assembly of tissues during morphogenesis through changes in individual cell behaviors and collective cell movements. Dynamic imaging, combined with quantitative analysis, is ideal for investigating fundamental questions in developmental biology involving cellular differentiation, growth control and morphogenesis. However, a reliable amniote model system that is amenable to the rigors of extended, high-resolution imaging and cell tracking has been lacking. To address this shortcoming, we produced a novel transgenic quail that ubiquitously expresses nuclear localized monomer cherry fluorescent protein (chFP). We characterize the expression pattern of chFP and provide concrete examples of how Tg(PGK1:H2B-chFP) quail can be used to dynamically image and analyze key morphogenetic events during embryonic stages X to 11
Bidirectional Relations between Parenting and Behavior Problems from Age 8 to 13 in Nine Countries
This study used data from 12 cultural groups in nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and the United States; N = 1,298) to understand the crossâcultural generalizability of how parental warmth and control are bidirectionally related to externalizing and internalizing behaviors from childhood to early adolescence. Mothers, fathers, and children completed measures when children were ages 8â13. Multipleâgroup autoregressive, crossâlagged structural equation models revealed that child effects rather than parent effects may better characterize how warmth and control are related to child externalizing and internalizing behaviors over time, and that parent effects may be more characteristic of relations between parental warmth and control and child externalizing and internalizing behavior during childhood than early adolescence
Parenting attributions and attitudes in cross-cultural perspective
SYNOPSIS Objective. This article used the Parenting Across Cultures Project to evaluate similarities and differences in mean levels and relative agreement between mothers' and fathers' attributions and attitudes in parenting in 9 countries. Design. Mothers and fathers reported their perceptions of causes of successes and failures in caregiving and their progressive versus authoritarian childrearing attitudes. Gender and cultural similarities and differences in parents' attributions and attitudes in 9 countries were analyzed: China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Results. Although mothers and fathers did not differ in any attribution, mothers reported more progressive parenting attitudes and modernity of childrearing attitudes than did fathers, and fathers reported more authoritarian attitudes than did mothers. Country differences also emerged in all attributions and attitudes that were examined. Mothers' and fathers' attributions and their attitudes were moderately correlated, but parenting attitudes were more highly correlated in parents than were attributions. Conclusions. We draw connections among the findings across the 9 countries and outline implications for understanding similarities and differences in mothers' and fathers' parenting attributions and attitudes
Editorial: Positive youth development, mental health, and psychological well-being in diverse youth
This is an editorial commentary on the Research Topic entitled: Editorial: Positive youth development, mental health, and psychological well-being in diverse youth. One impetus behind this Research Topic was to examine the ways in which positive development intersects with problematic aspects of development and behavior, with an emphasis on connections to indicators of mental health problems. The second impetus was to take an international approach, including youth from diverse countries and settings who were studied using a variety of etic and emic methods that correspondingly consider cross-culturally common features and features that vary across cultures
Classes of Intimate Partner Violence from Late Adolescence to Young Adulthood
Researchers do not agree on how intimate partner violence (IPV) emerges and changes from adolescence to young adulthood. This may be because change in these behaviors varies across individuals. The present study uses a longitudinal, person-centered approach to examine whether there are multiple classes or patterns of change in the perpetration of IPV during the transitional period from adolescence (age 18) to young adulthood (age 25) using data collected annually from a community sample of 484 participants. Latent class analysis was the analytic approach used. Results revealed three patterns for psychological IPV (Little-to-None, Minor/Increasing, and Extensive/Increasing) and two patterns for physical IPV (Little-to-None and Extensive). Patterns varied greatly in number of representatives, although they were more balanced in size for psychological than physical IPV. Variations in IPV behaviors were also revealed across classes, although as expected in a community sample, minor forms of IPV were more common than severe forms. In addition, classes differed in demographic and relationship status variables. These findings suggest that IPV may occur in multiple distinct patterns as opposed to one average pattern across a population. This suggests that interventions for IPV may need to be geared to differences in patterns to enhance their efficacy
Temporal Associations between Psychological and Physical Intimate Partner Violence: A Cross-Lag Analysis
The present study examined the relationship between psychological and physical forms of intimate partner violence (IPV) across four waves of data during the developmental period of young adulthood. The links from early psychological aggression to later physical aggression and from early physical aggression to later psychological aggression across waves were tested while controlling for their cross-time stabilities and concurrent associations. IPV data were collected annually from 434 young adult respondents involved in a romantic relationship at least once during the respective years from the ages of 22-25. On average, participants provided IPV data for three out of the four years covered by the study (M = 2.82; SD = 1.14). Results of a cross-lagged SEM model indicated significant cross-time stabilities as well as significant, positive concurrent associations for both forms of aggression. Most important to this study were the findings that, controlling for these stabilities and concurrent associations, early psychological aggression was a consistent positive predictor of later physical aggression across waves whereas the opposite direction from early physical aggression to later psychological aggression was either non-significant or significant and negative
