This study reports on the development and validation of an abridged version of the 50-item Autism-Spectrum Quotient (AQ), a self-report measure of autistic traits. We aimed to reduce the number of items whilst retaining high validity and a meaningful factor structure. The item reduction procedure was performed on data from 1,263 Dutch students and general population adults. The resulting 28-ite...

Ligninolytic fungi are unique among eukaryotes in their ability to degrade polycyclic aromatic hydrocarbons (PAHs), but the mechanism for this process is unknown. Although certain PAHs are oxidized in vitro by the fungal lignin peroxidases (LiPs) that catalyze ligninolysis, it has never been shown that LiPs initiate PAH degradation in vivo. To address these problems, the metabolism of anthracen...

Buss and Perry (1992) developed the Aggression Questionnaire (AQ) to assess aggressiveness as a personality trait in high school and college samples. The AQ has been used by researchers in United States, Italy, Germany, Netherland, Japan, Canada, and Greece. The present study is reported on an Arabic adapted version of the AQ among a sample of 510 Egyptian high school students. An exploratory f...

Many larval sponges possess pigment ring eyes that apparently mediate phototactic swimming. Yet sponges are not known to possess nervous systems or opsin genes, so the unknown molecular components of sponge phototaxis must differ fundamentally from those in other animals, inspiring questions about how this sensory system functions. Here we present molecular and biochemical data on cryptochrome,...

The Autism Spectrum Quotient (AQ) has been used to define the 'broader' (BAP), 'medium' (MAP) and 'narrow' autism phenotypes (NAP). We used a new Italian version of the AQ to test if difference on AQ scores and the distribution of BAP, MAP and NAP in autism parents (n = 245) versus control parents (n = 300) were replicated in a Sicilian sample. Parents of children with autism spectrum condition...

The revised attribution questionnaire (r-AQ) measures mental illness stigma. This study's purpose is to evaluate the factor structure of the (r-AQ) and examine the validity of the factor structure in adolescents. A convenience sample (n = 210) of adolescents completed the r-AQ and these data were used in exploratory (EFA) and confirmatory factor analyses (CFA). The EFA established a five item s...

BACKGROUND The Autism Spectrum Quotient (AQ) is a self-report questionnaire for quantifying autistic traits. This study tests whether the AQ can differentiate between parents of children with an autism spectrum condition (ASC) and control parents. In this paper, the use of the AQ to define the broader, medium and narrow autism phenotypes (BAP, MAP, NAP) is reported, and the proportion of parent...

It is unknown whether the Autism-spectrum quotient (AQ) can discriminate between Autism Spectrum Disorder (ASD) and Attention Deficit and Hyperactivity Disorder (ADHD) with or without comorbid Substance Use Disorder (SUD). ANOVA's were used to analyse the mean AQ (sub)scores of 129 adults with ASD or ADHD. We applied receiver operating characteristic (ROC) computations to assess discriminant po...

In this paper we use a piecewise constant Smolyak approximation algorithm to approximate functions whose partial mixed fractional derivatives of order 0 < α ≤ 1 in each variable are bounded. We prove that the L1 error of our approximation is of order (log card(Aq,s))(card(Aq,s)), where card(Aq,s) denotes the number of function evaluations used by the algorithm.

Abstract This paper presents the RST-AQ, a 22-item scale to measure affective states related three motivational systems postulated by Reinforcement Sensitivity theory (RST-AQ): Behavioral approach system (BAS), inhibition (BIS), and Fight-Flight-Freeze (FFFS). The subscales are internally consistent. Results show an overall support for construct validity of our RST-AQ measure. correlations with...
