US fathers' reports of bonding, infant temperament and psychosocial stress based on family sleep arrangements.

Background And Objectives: Evolutionary-grounded sleep research has been critical to establishing the mutual dependence of breastfeeding and nighttime sleep proximity for mothers and infants. Evolutionary perspectives on cosleeping also often emphasize the emotional motivations for and potential benefits of sleep proximity, including for parent-infant bonding. However, this potential link between infant sleep location and bonding remains understudied for both mothers and fathers.

Positive parenting, parenting stress, and child self-regulation patterns differ across maternal demographic risk.

We examined relations between positive parenting, parenting stress, and children's regulatory abilities across infancy and early childhood. First-time mothers and their infants ( = 682) were recruited prenatally. Mothers belonged to one of three potential demographic risk groups: adolescent mothers (AM), adult low-educated mothers (LEM), and adult high-educated mothers (HEM).

Friction and Adhesion Govern Yielding of Disordered Nanoparticle Packings: A Multiscale Adhesive Discrete Element Method Study.

Recent studies have demonstrated that amorphous materials, from granular packings to atomic glasses, share multiple striking similarities, including a universal onset strain level for yield. This is despite vast differences in length scales and in the constituent particles' interactions. However, the nature of localized particle rearrangements is not well understood, and how local interactions affect overall performance remains unknown.

The importance of early life touch for psychosocial and moral development.

One of the primary means of communicating with a baby is through touch. Nurturing physical touch promotes healthy physiological development in social mammals, including humans. Physiology influences wellbeing and psychosocial functioning.

Efficacy of a reminiscing and emotion training intervention on maltreating families with preschool-aged children.

The current investigation reports the results of a randomized controlled trial of a brief, relational intervention for maltreated preschool-aged children and their mothers, called Reminiscing and Emotion Training (RET). RET facilitates elaborative and emotionally supportive parent-child communication, which is an essential component of the parent-child relationship and is especially relevant for the preschool age period. Participants were 248 children between the ages of 3- to 6-years-old and their mothers.
