Tetrahedrally bonded ternary amorphous semiconductor alloys

The properties of tetrahedrally bonded ternary amorphous semiconductors a-CSiSn:H and a-CSiGe:H are reviewed with particular emphasis on the temperature dependence of dark conductivity and the coordination in random networks. It is shown here that the dark conductivity as a function of the temperature strongly depends on the carbon content and, more precisely, on the proportion of sp3 and sp2 sites in the carbon. Ternary alloys with different carbon contents are compared to binary alloys using the average coordination number. The ternary alloys have an average coordination number close to the optimal value predicted for amorphous covalent networks

Prevention and Reduction of Anxiety in Autistic Preschoolers Through an Autism-Specific Parent-Mediated Intervention: A Pilot Randomised Controlled Trial Evaluating Short and Longer Term Outcomes

\ua9 The Author(s) 2024. Anxiety is a common co-occurring condition for autistic preschoolers. Whilst there has been extensive research evaluating anxiety prevention/reduction interventions for neurotypical preschoolers, such research is limited for autistic children. Fifty-seven parents of autistic 4–5-year olds, with varying levels of anxiety, participated in a randomised controlled trial of an autism-specific, parent-mediated intervention (CLK-CUES) to prevent or reduce anxiety in autistic preschoolers. Baseline, short-term (post-intervention) and longer term (12 months follow-up) assessments included child anxiety (ASC-ASD-P and PAS-R), intolerance of uncertainty, and parent well-being. (Trial registration ACTRN12620001322921). There were no reports of harmful effects of the intervention or trial. Linear mixed models show a significant group x time interaction for ASC-ASD-P Total score and the Uncertainty subscale with medium and large effect sizes. Post-hoc analyses show a significant decline for only the intervention group in anxiety (specifically, anxiety around uncertainty) from pre-post intervention, maintained at one year follow-up. There was no change on the PAS-R or other ASC-ASD-P subscales. CLK-CUES shows promise as a way to prevent and reduce anxiety in young autistic children, specifically anxiety related to uncertainty. Trials with larger samples are warranted. Findings also highlight the importance of using measures designed for autistic children

Unmade Film

Unmade Film is an expansive collection of audio-visual works that point to the structure of a film but never fully become one. Unmade Film takes as its starting point the mental hospital Kfar Sha'ul in Jerusalem. Initially specialising in the treatment of Holocaust survivors – including a relative of the artist – it was established in 1951 using the remains of the Palestinian village Deir Yassin that had been depopulated in a massacre by Zionist paramilitaries in April 1948. The work and its different elements evolved out of exchanges and collaborations with psychologists, psychiatric nurses, historians, musicians, pupils, amateur actors, curators, artists and others. The publication of Unmade Film brings together the different works by Uriel Orlow and texts expanding on the themes of Unmade Film, including the historical context (Ilan Pappé), discussions around trauma and haunting (Yo’ad Ghanadry and Avery Gordon), film without film (Erik Bullot), a critique of ruins (Esmail Nashif)

Elaboration of FAU-type zeolite beads with good mechanical performances for molecular decontamination

FAU-type zeolite beads were formed through an shearer/mixer using organic binder (carboxymethylcellulose (CMC)) or inorganic binder (anhydrous sodium metasilicate (Na2SiO3)).</p
