OBJECTIVE This multi-method, longitudinal study examines the negotiation of autonomy and relatedness between teens and their mothers as etiologic predictors of perpetration and victimization of dating aggression two years later. METHOD Observations of 88 mid-adolescents and their mothers discussing a topic of disagreement were coded for each individual's demonstrations of autonomy and related...

Synapse elimination is a widespread developmental process in the peripheral and central nervous system that brings about refinement of neural connections through epigenetic mechanisms. Here we describe recent advances concerning the role of the pattern of motoneuronal firing, synchronous or asynchronous, in neuromuscular synapse elimination.

Professor Joshua Schwartz’s theory can be a useful tool for integrating law & development (L&D) and comparative law, despite its limitations. He argues that exceptionalism tendency can be found in contract performance phase in US, which can be explained by the central role of the military procurement in the US public procurement law. He further suggests that developing countries should learn fl...

Plants colonized the terrestrial environment over 450 million years ago. Since then, shoot architecture has evolved in response to changing environmental conditions. Our current understanding of the innovations that altered shoot morphology is underpinned by developmental studies in a number of plant groups. However, the least is known about mechanisms that operate in ferns--a key group for und...

A discrete model provides a useful framework for experimentalists to understand the interactions between growing tissues and other biological mechanisms. A cellular automata (CA) model with domain growth, cell motility and cell proliferation, based on cellular exclusion processes, is developed here. Average densities can be defined from the CA model and a continuum representation can be determi...

An increasing number of connectionist models have been proposed to explain behavioral deficits in developmental disorders. These simulations motivate serious consideration of the theoretical implications of the claim that a developmental disorder fits within the parameter space of a particular computational model of normal development. The authors examine these issues in depth with respect to a...

INTRODUCTION Global developmental delay (GDD) affects 1%-3% of the population of children under 5 years of age, making it one of the most common conditions presenting in paediatric clinics; causes are exogenous, genetic (non-metabolic) or genetic (metabolic). Recent advances in biotechnology and genetic testing mean that the investigations available to perform for children under 5 years are inc...

background and objectives: motor development is considered as a part of the process of growth and development in which the child, firstly gains control over his own body function, and then utilizes it for interaction and manipulation with the environment. the aim of this study was to standardize of peabody developmental motor scale (pdms) in normal children aged 72 to 83 months living in tehran...

Recent small-scale studies have shown a positive association between central obesity and self-reported pain levels. This study attempts to replicate the finding in a survey of over 1,000,000 individuals in the United States. The Gallup Organization conducted a proprietary survey between 2008 through 2010 where 1,062,271 randomly selected individuals in the United States participated in a teleph...

We propose a developmental process which may link the development of handedness with the development of hemispheric specialization for speech processing. Using Arbib's proposed sequence of sensorimotor development of manual skills and gestures (that he considers to be the basis of speech gestures and proto-language), we show how the development of hand-use preferences in proto-reaching skills c...
