Laser sintering of polyamide lattice-based lightweight fairing components for subsequent racetrack testing requires a high quality and a reliable design. Hence, the purpose of this study was to develop a design methodology for such additively manufactured prototypes, considering efficient generation and structural simulation of boundary conformal non-periodic lattices, optimization of production parameters as well as experimental validation.

Multi-curved, sandwich structure-based demonstrators were designed, simulated and experimentally tested with boundary conformal lattice cells. The demonstrator’s non-periodic lattice cells were simplified by forward homogenization processes. To represent the stiffness of the top and bottom face sheet, constant isotropic and mapped transversely isotropic simulation approaches were compared. The dimensional accuracy of lattice cells and demonstrators were measured with a gauge caliper and a three-dimensional scanning system. The optimized process parameters for lattice structures were transferred onto a large volume laser sintering system. The stiffness of each finite element analysis was verified by an experimental test setup including a digital image correlation system.

The stiffness prediction of the mapped was superior to the constant approach and underestimated the test results with −6.5%. Using a full scale fairing the applicability of the development process was successfully demonstrated.

The design approach elaborated in this research covers aspects from efficient geometry generation over structural simulation to experimental testing of produced parts. This methodology is not only relevant in the context of motor sports but is transferrable for all additively manufactured large scale components featuring a complex lattice sub-structure and is, therefore, relevant across industries.

This study aims to understand whether psychotropic prescribing practices for people with intellectual disabilities are in keeping with best practice guidelines.

This service evaluation project was a retrospective analysis of routinely collected data from the care records of all 36 people with intellectual disability discharged from an intellectual disability assessment and treatment unit during the first five years of the Stop Over medicating People with Intellectual Disabilities and/or autistic people (STOMP) initiative. Data were gathered at four time points (pre-admission, discharge, 6- and 12-month follow-up) before being analysed to understand whether psychotropic prescribing differed among people with different clinical characteristics/traits/diagnoses. Changes over time were also explored to ascertain whether and how prescribing altered from admission to discharge, and over the subsequent year of community living.

Most people with intellectual disabilities left the assessment and treatment unit on fewer regular psychotropic medications and at lower doses than at admission. These optimised regimes were still apparent 12 months post-discharge, suggesting effective discharge planning and community care packages. Inpatients with severe intellectual disabilities generally received more anxiolytics and hypnotics, at higher doses. Autistic people tended to receive more psychotropics in total and at higher cumulative doses, a pattern that persisted post discharge. A third of the sample were admitted on regular anti-psychotic medications despite having no corresponding psychotic diagnosis, a proportion that remained relatively stable through discharge and into the community.

This study highlights subsets of the intellectual disability population at particular risk of receiving high doses of psychotropics and a feasible template for providers intending to undertake STOMP-focused evaluations.

This study explored the experiences of college staff members engaged in advancing LGBTQ equity at a small fine arts college in the Midwestern United States. This qualitative case study advanced a conceptual framework for queer leadership in higher education. Findings illuminate how campus leaders engaged queer leadership strategies and LGBTQ advocacy to advance LGBTQ equity through college policy and practice. This study reveals rich implications for college administrators and higher education leaders advancing change for LGBTQ equity.
