A linear latent growth curve mixture model is presented which includes switching between growth curves. Switching is accommodated by means of a Markov transition model. The model is formulated with switching as a highly constrained multivariate mixture model and is fitted using the freely available Mx program. The model is illustrated by analyzing data from the National Longitudinal Survey of Y...

Abstract. We continue to study a model of disordered interface growth in two dimensions. The interface is given by a height function on the sites of the one–dimensional integer lattice and grows in discrete time: (1) the height above the site x adopts the height above the site to its left if the latter height is larger, (2) otherwise, the height above x increases by 1 with probability px. We as...

Nanoscale self-assembly is naturally subject to impediments at the nanoscale. The recently developed ability to follow processes at the molecular level forces us to resolve older, coarse-grained concepts in terms of their molecular mechanisms. In this Letter, we highlight one such example. We present evidence based on experimental and simulation data that one of the cornerstones of crystal grow...

We studied nucleation and crystal growth in two polypropylene samples by analyzing the number of spherulites, their size, and shape for various treatments in a hot-stage microscope. The consistency of nucleation and growth data were tested by using overall crystallization experiments and the Jonhson–Mehl–Avrami–Kolmogorov Q1 equation. In isothermal conditions, for temperatures, TC, varying betw...

We study how economic growth is affected by demographics in an OLG model with a realistic survival law. Individuals optimally chose the dates at which they leave school to work and at which they retire. Endogenous growth arises thanks to the accumulation of generation-specific human capital. Favorable shifts in the survival probabilities induce longer schooling and later retirement but have an ...

We model consumption and dividend growth as di¤erent processes across two latent regimes. We estimate the equilibrium model over 1930-2009 and show that the second regime is associated with recessions, market downturns, higher risk premia, lower consumption and dividend growth, higher volatility of returns and growth rates, and lower market-wide price-dividend ratio. The model performs better a...

The question of human resources is central to the success of VISION 2020 and of any health programme. The VISION 2020 global initiative document clearly spelt out what personnel was required and, more recently, the World Health Organization document on human resources for health care made recommendations on the type and number of people needed in order to meet all our objectives in global healt...

The purpose of this article is to introduce non-verbal tools as a way to initiate the psychosocial support response after a major disaster. The psychosocial interventions that follow the application of the Non Verbal Tool in its different configurations are based on the principle of fostering and strengthening the social and psychological attributes among the community members. The various psyc...

Family caregivers of persons following neurotrauma function as de facto extensions of our health care system. Their challenges may result in negative consequences for their physical and mental health, which directly impacts the well-being of their care-recipient. In this paper, we survey current practices in providing caregiver support, outline considerations for developing collaborative interv...

Objective The individually delivered Supervising for Home Safety (SHS) program improves caregivers' injury-related beliefs and supervision practices. The current randomized controlled trial used a group delivery in a community setting and assessed program impact, feasibility, and acceptance. Methods Caregivers of 2-5-year-olds were randomized to receive either the SHS or an attention-matched ...
