    Incremental Clinical Utility of ADHD Assessment Measures with Latino Families

    Attention-Deficit/Hyperactivity Disorder (ADHD) is a common disorder beginning in childhood, with related symptoms and impairment across settings often persisting into adolescence and adulthood if effective treatment is not provided (Bernardi et al., 2012). Therefore, the early and accurate assessment and diagnosis of ADHD is critical. While the prevalence of ADHD symptomatology has been found to be consistent between Latinos and European Americans (Morgan, Hillemeir, Farkas, & Maczuga, 2014), there is little research on the best practices for assessing ADHD in Latinos. The current study sought to examine the incremental clinical utility of two parent- and teacher-report measures of ADHD symptomatology and functional impairment used to assess ADHD in a sample of Latino children. A sample of Latino schoolchildren (N=53) was recruited to participate in the current study, along with their primary parents and teachers; a comprehensive ADHD assessment was conducted for each participant. Results suggest that teachers in the current sample had a higher rate of agreement with final clinical judgment than did parents in the current sample. Additionally, results suggest that parent- and teacher-reports of functional impairment did not add incremental utility in predicting ADHD diagnostic status, beyond that of parent- and teacher-reports of ADHD symptomatology; follow-up analyses suggest why this may be the case. Lastly, results suggest that teacher-reports of ADHD symptoms and functional impairment added incremental utility in predicting ADHD diagnostic status, beyond parent-reports of ADHD symptoms and functional impairment. Clinical implications of these findings will be discussed

    Relating emotional intelligence to academic achievement among university students in Barbados

    This study investigated the relationships between emotional intelligence and academic achievement among 151 undergraduate psychology students at The University of the West Indies (UWI), Barbados, making use of Barchard (2001)’s Emotional Intelligence Scale and an Academic Achievement Scale. Findings revealed significant positive correlations between academic achievement and six of the emotional intelligence components, and a negative correlation with negative expressivity. The emotional intelligence components also jointly contributed 48% of the variance in academic achievement. Attending to emotions was the best predictor of academic achievement while positive expressivity, negative expressivity and empathic concern were other significant predictors. Emotion-based decision-making, responsive joy and responsive distress did not make any significant relative contribution to academic achievement, indicating that academic achievement is only partially predicted by emotional intelligence. These results were discussed in the context of the influence of emotional intelligence on university students’ academic achievement.peer-reviewe

    Synergy between conventional phosphorus fire retardants and organically-modified clays can lead to fire retardancy of styrenics

    Get PDF
    Polystyrene–clay nanocomposites combined with phosphorous-containing fire retardants have been prepared and used to explore the thermal stability and mechanical properties of the polymer formed. The amounts of fire retardants and clay used were varied to study the effect of each on thermal stability and mechanical properties of the polymer. The samples were prepared by bulk polymerization and analyzed by X-ray diffraction, thermogravimetric analysis, cone calorimetry, Fourier Transform infrared spectroscopy and the evaluation of mechanical properties. The thermal stability of the polymers is enhanced by the presence of the phosphorus-containing fire retardants

    Enhanced Fire Retardancy of Vinyl Ester Resins by Combination of Additives

    In pursuit of fire-retardant materials, vinyl ester resins were combined with commercially available fire retardants at lower loadings than that at which they are usually effective when used alone. The thermal stability and flammability of the various combinations of fire retardants were evaluated by thermogravimetric analysis and cone calorimetric analysis. With some combinations, the 50% degradation temperature was improved by about 5-10ÂşC Different additives affected the flammability to varying extents and some combinations resulted in an enhanced fire retardancy compared to the additives used alone. The combinations that showed the best reductions in the peak heat release rate (PHRR) were further used to prepare glass reinforced resins and the flammability of those systems was also evaluated using cone calorimetry

    Early exposure to environmental toxin contributes to neuronal vulnerability and axonal pathology in a model of familial ALS

    Get PDF
    Adult onset amyotrophic lateral sclerosis (ALS) arises due to progressive and irreversible functional deficits to the central nervous system, specifically the loss of motor neurons. Sporadic ALS causality is not well understood, but is almost certainly of multifactorial origin involving a combination of genetic and environmental factors. The discovery of endemic ALS in the native Chamorro population of Guam during the 1950s and the co-occurrence of parkinsonism and dementia in some patients led to searches for an environmental toxins that could be responsible. In the present paper, we report that an environmental neurotoxin enhances mutant superoxide dismutase (SOD)-induced spinal motor neuron death and pathology and induces motor axon abnormalities. These results cumulatively confirm earlier findings that exposure to an environmental toxin is sufficient to produce the disease phenotype and indicate a role for gene-environment interaction in some forms of the disease

    Estimation of fractal dimension for a class of Non-Gaussian stationary processes and fields

    Full text link
    We present the asymptotic distribution theory for a class of increment-based estimators of the fractal dimension of a random field of the form g{X(t)}, where g:R\to R is an unknown smooth function and X(t) is a real-valued stationary Gaussian field on R^d, d=1 or 2, whose covariance function obeys a power law at the origin. The relevant theoretical framework here is ``fixed domain'' (or ``infill'') asymptotics. Surprisingly, the limit theory in this non-Gaussian case is somewhat richer than in the Gaussian case (the latter is recovered when g is affine), in part because estimators of the type considered may have an asymptotic variance which is random in the limit. Broadly, when g is smooth and nonaffine, three types of limit distributions can arise, types (i), (ii) and (iii), say. Each type can be represented as a random integral. More specifically, type (i) can be represented as the integral of a certain random function with respect to Lebesgue measure; type (ii) can be represented as the integral of a second random functio
