An Initial Examination of Girls’ Cognitions of Their Relationally Aggressive Peers as a Function of Their Own Social Standing
The primary aim of the present study was to examine girls’ cognitions of their relationally aggressive peers as a function of their own relationally aggressive and sociometric status. Participants were 151 4th- and 5th-grade girls attending four public elementary schools. Findings suggest that relationally aggressive girls tend to display a relatively cautious and wary social cognitive style in relationally provocative social situations. For example, they view relationally aggressive behaviors as being relatively stable and unchanging, and they exhibit little trust for peers who exhibit a similar behavioral style. Results suggest that rejected girls may exhibit markedly different social processing styles depending upon whether they are also relationally aggressive themselves. For instance, rejected-relational aggressors appear to interpret others’ negative behaviors as being quite intentional. In contrast, rejected-nonrelational aggressors demonstrate relatively high levels of trust for peers who treat them poorly while also interpreting these peers’ behaviors as being relatively unintentional. Implications for designing multilevel interventions to combat relational aggressive problems are discussed
PACT: An initiative to introduce computational thinking to second-level education in Ireland
PACT (Programming ∧ Algorithms ⇒ Computational Thinking) is a partnership between
researchers in the Department of Computer Science at Maynooth University and teachers at
selected post-primary schools around Ireland. Starting in September 2013, seven Irish
secondary schools took part in a pilot study, delivering material prepared by the PACT team
to Transition Year students. Three areas of Computer Science were identified as being key to
delivering a successful course in computational thinking, namely, programming, algorithms
and computability. An overview of the PACT module is provided, as well as analysis of the
feedback obtained from students and teachers involved in delivering the initial pilot

The predictive validity of parent and teacher reports of ADHD symptoms
The objectives were to evaluate the ability of the Inattention and Hyperactivity-Impulsivity factors of the ADHD Rating Scale-IV to differentiate children with ADHD from a control group and to discriminate children with different subtypes of ADHD. Also, we sought to determine optimal cutoff scores on the teacher and parent versions of this scale for making diagnostic decisions about ADHD. In a sample of 92 boys and girls 6 to 14 years of age referred to a regional ADHD program, we assessed ADHD diagnostic status using categorical and dimensional approaches as well as parent- and teacher-report measures. Logistic regression analyses showed that the Inattention and Hyperactivity-Impulsivity factors of the ADHD Rating Scale-IV were effective in discriminating children with ADHD from a control group and differentiating children with ADHD, Combined Type from ADHD, Inattentive Type. Although both teacher and parent ratings were significantly predictive of diagnostic status, teacher ratings made a stronger contribution to the prediction of subtype membership. Using symptom utility estimates, optimal cutoff scores on the Inattention and Hyperactivity-Impulsivity scales for predicting subtypes of ADHD were determined
Survey of Obstetrician-Gynecologists in the United States About Toxoplasmosis
Background: Although the incidence of toxoplasmosis is low in the United States, up to 6000 congenital cases occur annually. In September 1998, the Centers for Disease Control and Prevention held a conference about toxoplasmosis; participants recommended a survey of the toxoplasmosis-related knowledge and practices of obstetrician-gynecologists and the development of professional educational materials for them. Methods: In the fall of 1999, surveys were mailed to a 2% random sample of American College of Obstetricians and Gynecologists (ACOG) members and to a demographically representative group of ACOGmembers known as the Collaborative Ambulatory Research Network (CARN). Responses were not significantly different for the random and CARN groups for most questions (p value shown when different). Results: Among 768 US practicing ACOG members surveyed, 364 (47%) responded. Seven per cent (CARN 10%, random 5%) had diagnosed one or more case(s) of acute toxoplasmosis in the past year. Respondents were well-informed about how to prevent toxoplasmosis. However, only 12% (CARN 11%, random 12%) indicated that a positive Toxoplasma IgM test might be a false–positive result, and only 11% (CARN 14%, random 9%) were aware that the Food and Drug Administration sent an advisory to all ACOG members in 1997 stating that some Toxoplasma IgM test kits have high false–positive rates. Most of those surveyed (CARN 70%, random 59%; X(2) p < 0.05) were opposed to universal screening of pregnant women. Conclusions: Many US obstetrician-gynecologists will encounter acute toxoplasmosis during their careers, but they are frequently uncertain about interpretation of the laboratory tests for the disease. Most would not recommend universal screening of pregnant women
Density Profile Asymptotes at the Centre of Dark Matter Halos
For the spherical symmetric case, all quantities describing the relaxed dark
matter halo can be expressed as functions of the gravitational potential
. Decomposing the radial velocity dispersion with respect to
at very large and very small radial distances the possible asymptotic
behavior for the density and velocity profiles can be obtained. If reasonable
boundary conditions are posed such as a finite halo mass and force-free halo
centre the asymptotic density profiles at the centre should be much less steep
than the profiles obtained within numerical simulations. In particular cases
profiles like Plummer's model are obtained. The reasons of that seeming
discrepancy with respect to the results of N-body simulations are discussed.Comment: Accepted for publication in Astronomy & Astrophysics, LaTeX, 7 pages,
