Cognitive Profiles and the Impact of Medication on Children with Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequently diagnosed disorders in children and adolescents. Individuals with ADHD often display behavioral symptoms, including inattention and/or impulsivity, which can also lead to struggles in the school setting. Current research has suggested that deficits in processing speed and working memory are common in individuals diagnosed with ADHD and are often seen on measures of cognitive ability. Positive outcomes have been associated with the use of psychostimulant medication to treat the symptoms of ADHD, although little research has supported this form of treatment to improve cognitive functioning in individuals diagnosed with ADHD. The current study replicated and expanded on Friedman (2006) and McLaughlin’s (2009) studies. The purpose of this study was to compare the cognitive profiles of children diagnosed with ADHD and a control sample. The cognitive profiles were analyzed at the Full Scale, Index, and Subtest levels. In addition, the current study sought to determine whether or not the medication status impacted performance on the cognitive measures. The results of this study indicated that individuals with ADHD did perform lower on measures of Full Scale IQ, Perceptual Reasoning, Working Memory and Processing Speed. It was also noted that the use of medication yielded higher performance, as compared with the nonmedicated ADHD group. At the subtest level analysis, ADHD individuals typically performed better on the following task pairs: they worked better on verbal reasoning than on working memory tasks; they were more successful with perceptual reasoning than with processing speed tasks. In addition, ADHD groups also performed roughly the same on the following task pairs: on nonverbal reasoning and working memory tasks, on verbal reasoning and processing speed, on verbal reasoning and perceptual reasoning, and on working memory and processing speed. Regarding medication status, positive trends were noted for medication use, but minimal statically significant results were found. Significant results were found in favor of medication use for the VCI \u3e PSI and PRI \u3e VCI comparisons

Customised Rapid Manufactured Parts: Technology and Case Studies from the Custom-Fit Project

The design and manufacture of individually customised products is generally restricted to bespoke clothing or footwear for very wealthy customers. The aim of the Custom-Fit project was to develop a fast, flexible and economically viable route for the manufacture of individually customised parts. These products not only provide improved comfort levels but also provide better functional performance, including enhanced safety for the user. This 4.5 year, European Commission subsidised €16 million project, supported by the EU, involving 30 partners across the breadth of the Europe finished in early 2009. This paper will showcase the technology developed: CAD packages which automate the design process and three new rapid manufacturing methods. It will also include case studies on a range of customised products, including customised Motorcycles helmets. The case studies not only demonstrate the performance benefits of individual customisation but also show the potential for new approaches to product design.

Laser Printed Elastomeric Parts and Their Properties

The precise deposition of polymeric toner powder by laser printing is reliant on having powder particles with appropriate flow and uniform charge properties. Nanometer sized particles known as flow control agents (FCA) and charge control agents (CCA) are used to modify powder behaviour to provide the appropriate characteristic for printing. This paper shows how varying the quantity of FCA applied to the surface of Somos201 particles can affect the elongation to failure and ultimate tensile strength of laser printed tensile test specimens.Mechanical Engineerin

Unexpected earthquake hazard revealed by Holocene rupture on the Kenchreai Fault (central Greece): Implications for weak sub-fault shear zones

High-resolution elevation models, palaeoseismic trenching, and Quaternary dating demonstrate that the Kenchreai Fault in the eastern Gulf of Corinth (Greece) has ruptured in the Holocene. Along with the adjacent Pisia and Heraion Faults (which ruptured in 1981), our results indicate the presence of closely-spaced and parallel normal faults that are simultaneously active, but at different rates. Such a configuration allows us to address one of the major questions in understanding the earthquake cycle, specifically what controls the distribution of interseismic strain accumulation? Our results imply that the interseismic loading and subsequent earthquakes on these faults are governed by weak shear zones in the underlying ductile crust. In addition, the identification of significant earthquake slip on a fault that does not dominate the late Quaternary geomorphology or vertical coastal motions in the region provides an important lesson in earthquake hazard assessment.This work forms part of the NERCand ESRC-funded project ‘Earthquakes Without Frontiers’, and was partly funded by the NERC grant ‘Looking Inside the Continents from Space’

Carnival of invention

© 2019, Institut für Qualitative Forschung,Internationale Akademie Berlin gGmbH. All rights reserved. In this report we present a reflection on the Collaborative Poetics Network’s first “Carnival of Invention” which was held on 15th June 2018 at the University of Brighton, England. Collaborative poetics is an arts-based research method that brings together expertise from artists, academics, and community participants, to share knowledge and promote social change through engaging and accessible ways. On the day of the Carnival over 40 contributors from around the world came to participate in a series of workshops, presentations, installations and displays. In this article we outline the themes addressed on the day and the media utilized in these interactive and experiential sessions. We argue that this event supported the benefits of arts-based research in developing, analyzing, and communicating rich data sets. Finally, we provide evaluation and reflections from the event (including in haiku, a traditional Japanese form of poetry), in an attempt to creatively capture the events of the day

Mg isotopic heterogeneity, Al-Mg isochrons, and canonical ^(26)Al/^(27)Al in the early solar system

There is variability in the Mg isotopic composition that is a reflection of the widespread heterogeneity in the isotopic composition of the elements in the solar system at approximately 100 ppm. Measurements on a single calcium-aluminum-rich inclusion (CAI) gave a good correlation of ^(26)Mg/^(24)Mg with ^(27)Al/^(24)Mg, yielding an isochron corresponding to an initial (^(26)Al/^(27)Al)_o = (5.27 ± 0.18) × 10^(−5) and an initial (^(26)Mg/^(24)Mg)_o = −0.127 ± 0.032‰ relative to the standard. This isochron is parallel to that obtained by Jacobsen et al. (2008), but is distinctively offset. This demonstrates that there are different initial Mg isotopic compositions in different samples with the same ^(26)Al/^(27)Al. No inference about uniformity/heterogeneity of ^(26)Al/^(27)Al on a macro scale can be based on the initial (^(26)Mg/^(24)Mg)_o values. Different values of ^(26)Al/^(27)Al for samples representing the same point in time would prove heterogeneity of ^(26)Al/^(27)Al. The important issue is whether the bulk solar inventory of ^(26)Al/^(27)Al was approximately 5 × 10^(−5) at some point in the early solar system. We discuss ultra refractory phases of solar type oxygen isotope composition with ^(26)Al/^(27)Al from approximately 5 × 10^(−5) to below 0.2 × 10^(−5). We argue that the real issues are: intrinsic heterogeneity in the parent cloud; mechanism and timing for the later production of ^(16)O-poor material; and the relationship to earlier formed ^(16)O-rich material in the disk. ^(26)Al-free refractories can be produced at a later time by late infall, if there is an adequate heat source, or from original heterogeneities in the placental molecular cloud from which the solar system formed
