An German Short-Version of the Sensory Perception Quotient for Adults With Autism Spectrum Disorder

Sensory features in autism spectrum disorder (ASD) have received increasing interest in clinical work and research during the recent years. With the Sensory Perception Quotient (SPQ), Tavasolli and colleagues have produced a self-rating scale for adults with ASD that measures sensory hyper-sensitivity in different sensory modalities, without also tapping cognitive or motivational aspects that precede or follow autistic sensory experiences. Here, we present the results of a translation of the SPQ to German and its short version as well as their validation in samples of autistic or neuro-typical participants. We, furthermore, present the psychometric properties and validities of Tavasolli's original SPQ-short version as well as an alternative short version based on different psychometric item-selection criteria. We can show here that our alternative SPQ-short version, overlapping with the original short-version in 61% of its items, exhibits superior reliabilities, reasonable concurrent validities with other related measures. It, furthermore, exhibits excellent differentiation between autistic and non-autistic samples, underscoring its utility as a screening instrument in research and a clinical instrument to supplement the ASD diagnostic process

Creating a Dichotomous Key for the Identification of Trade Axes (1600-1900) in the Western Great Lakes Region, version 1.2022

This report is the result of a semester-long project in an advanced archaeological methods course at the University of Minnesota Duluth (UMD). The goal of this research was to create a trade axe identification guide for museum curators using a technique called the dichotomous key. Carried out in the Fall of 2022 as the laboratory component of a class, the intent of the project was to teach students data collection, analysis, and dissemination through hands-on work.Jones, Jennifer E; Bruentrup, Hannah Rose; Colberg, Alli; Herman, Adam M; Krzyzaniak, Jesse; Nelson, Race; Roering, Trinity; Soderberg, Sarah; Sybrant, Holly; Walpole, Erin; Peterson, David H.

Meso-Archaean and Palaeo-Proterozoic sedimentary sequence stratigraphy of the Kaapvaal Craton

The Kaapvaal Craton hosts a number of Precambrian sedimentary successions which were deposited between 3105 Ma (Dominion Group) and 1700 Ma (Waterberg Group) Although younger Precambrian sedimentary sequences outcrop within southern Africa, they are restricted either to the margins of the Kaapvaal craton, or are underlain by orogenic belts off the edge of the craton. The basins considered in this work are those which host the Witwatersrand and Pongola, Ventersdorp, Transvaal and Waterberg strata. Many of these basins can be considered to have formed as a response to reactivation along lineaments, which had initially formed by accretion processes during the amalgamation of the craton during the Mid-Archaean. Faulting along these lineaments controlled sedimentation either directly by controlling the basin margins, or indirectly by controlling the sediment source areas. Other basins are likely to be more controlled by thermal affects associated with mantle plumes. Accommodation in all these basins may have been generated primarily by flexural tectonics, in the case of the Witwatersrand, or by a combination of extensional and thermal subsidence in the case of the Ventersdorp, Transvaal and Waterberg. Wheeler diagrams are constructed to demonstrate stratigraphic relationships within these basins at the first- and second-order levels of cyclicity, and can be used to demonstrate the development of accommodation space on the craton through the Precambrian.AJB, PGE and MR gratefully acknowledge Gold Fields of South Africa, the National Research Foundation and the University of Pretoria for funding.http://www.elsevier.com/locate/marpetgeonf201
