Colorless nonlinear optical D-p-A polymers with sulfones as electron acceptors

Colorless side-chain methacrylate copolymers exhibiting relatively narrow charge-transfer bands at 335 nm and second-order optical nonlinearities up to d33 = 4.3 pmV-1 (at 1064 nm) were synthesized and characterized. [on SciFinder (R)

Psychometric Properties of the Dutch Contextual Assessment of Social Skills (CASS):An Independent Observational Outcome Measure of Social Skills in Autistic Adolescents

The goal of this study was to translate and adapt the original 9-item of the Contextual Assessment of Social Skills (CASS) to a Dutch version and assess its psychometric qualities. Autistic adolescents aged 12 to 18 years (n = 99) took part in a randomized controlled trial. In this study, pre-intervention data were utilized. The original CASS was adapted to ensure cultural relevance and the content validity was assessed. Data was used to assess reliability and structural validity, using confirmatory factor analysis. 4-item were added to the CASS during the adaptation to better align with the objectives of the experimental intervention. The original 9-item had inter-item correlations between.01 and.70. The Cronbach’s alpha for the original 4-item total score was moderate (α =.69), while for a 7-item total score, it was high (α =.86). This 7-item total score had a sufficient model fit (Comparative Fit Index =.90). This total score had a significant correlation with the Assertion subscale of the Social Skills Improvement System-Adolescent (SSIS-A) (r = 0.26, p &lt;.01), and the Social Responsiveness Scale-2 (SRS-2) total score (r = − .21, p =.04) indicating sufficient convergent validity. The CASS total score was not correlated with the Repetitive and Restricted Behavior scale of the SRS-2 (r = − .08, p =.43), indicating sufficient divergent validity. The Dutch CASS can be considered a conceptually sound and reliable observational instrument for assessing social conversational skills in Dutch autistic youth. Further evaluation of its feasibility when implemented in practice, outside of clinical research, is needed.

The mEPN scheme: an intuitive and flexible graphical system for rendering biological pathways

<p>Abstract</p> <p>Background</p> <p>There is general agreement amongst biologists about the need for good pathway diagrams and a need to formalize the way biological pathways are depicted. However, implementing and agreeing how best to do this is currently the subject of some debate.</p> <p>Results</p> <p>The modified Edinburgh Pathway Notation (mEPN) scheme is founded on a notation system originally devised a number of years ago and through use has now been refined extensively. This process has been primarily driven by the author's attempts to produce process diagrams for a diverse range of biological pathways, particularly with respect to immune signaling in mammals. Here we provide a specification of the mEPN notation, its symbols, rules for its use and a comparison to the proposed Systems Biology Graphical Notation (SBGN) scheme.</p> <p>Conclusions</p> <p>We hope this work will contribute to the on-going community effort to develop a standard for depicting pathways and will provide a coherent guide to those planning to construct pathway diagrams of their biological systems of interest.</p
