We characterized the body size (as snout-vent length), age, sexual size dimorphism, and growth rate in a population of one of the larger riparian frog from Madagascar (Mantidactylusgrandidieri) from a rainforest patch close to Vevembe, SE Madagascar. We identified a significant female-biased sexual size dimorphism. Age was estimated using phalangeal skeletochronology and was significantly higher in females than in males. Modal age class turned out to be 4 years in both sexes but a large percentage of adult females (75%) fell in the 5–6 years-old classes, while no male exceeded 4 years. We here report M.grandidieri as a medium-long-lived anuran species. Von Bertalanffy’s model showed similar growth trajectories between the sexes although the growth coefficient in females (k = 0.335) was slightly but not significantly higher than in males (k = 0.329).

The purpose of this study was to examine whether parental self-efficacy (PSE) is associated with change in infant weight-for-length z score (WLZ) from age 3 to 12 months. Data were drawn from the Infant Care, Feeding, and Risk of Obesity study, conducted with low-income, African American mother–infant dyads ( n = 127). PSE was measured at infant age of 3 months. Infant anthropometrics were measured at infant age of 3 and 12 months, WLZ change between these time points was calculated, and infants stratified into WLZ change categories (expected, excessive, or slow). To analyze the data, ANCOVA, multiple regression, and post hoc techniques were used. Controlling for infant birthweight, PSE at 3 months was associated with infant WLZ change (η2 = 0.05, p = .04). Mothers of infants who exhibited excessive growth had higher PSE than mothers of infants who exhibited slow growth (Tukey-adjusted p = .03). This finding suggests that infants of mothers with high PSE may have increased obesity risk, but more research is needed.

BackgroundPhysical aggression (PA) tends to have its onset in infancy and to increase rapidly in frequency. Very little is known about the genetic and environmental etiology of PA development during early childhood. We investigated the temporal pattern of genetic and environmental etiology of PA during this crucial developmental period.MethodParticipants were 667 twin pairs, including 254 monozygotic and 413 dizygotic pairs, from the ongoing longitudinal Quebec Newborn Twin Study. Maternal reports of PA were obtained from three waves of data at 20, 32 and 50 months. These reports were analysed using a biometric Cholesky decomposition and linear latent growth curve model.ResultsThe best-fitting Cholesky model revealed developmentally dynamic effects, mostly genetic attenuation and innovation. The contribution of genetic factors at 20 months substantially decreased over time, while new genetic effects appeared later on. The linear latent growth curve model revealed a significant moderate increase in PA from 20 to 50 months. Two separate sets of uncorrelated genetic factors accounted for the variation in initial level and growth rate. Non-shared and shared environments had no effect on the stability, initial status and growth rate in PA.ConclusionsGenetic factors underlie PA frequency and stability during early childhood; they are also responsible for initial status and growth rate in PA. The contribution of shared environment is modest, and perhaps limited, as it appears only at 50 months. Future research should investigate the complex nature of these dynamic genetic factors through genetic–environment correlation (rGE) and interaction (G × E) analyses.

Effective Interventions

The present study aimed to investigate the development and interplay of emotional stability and affective self–regulatory efficacy beliefs through adolescence to young adulthood. A latent growth curve approach was used to investigate level and stability of emotional stability and self–efficacy in managing negative emotions and in expressing positive emotions. We found that initial levels of emotional stability and self–efficacy beliefs are highly correlated. In accordance with the posited hypothesis, the growth rate of perceived self–efficacy in managing negative emotions predicted the growth rate of emotional stability, whereas the opposite path was not significant. The growth rates of perceived self–efficacy in expressing positive emotions and emotional stability were not related to each other. Taken together, these findings point to self–efficacy beliefs as instrumental to the change of traits. Practical implications of results are discussed, highlighting the role of social cognitive theory in supplying the proper strategies to design effective interventions to enable people to make the best use of their potentials.
