Episode 95: Monuments and Memorials: A conversation with Lydia Brandt
No full textAs an architectural historian, Lydia Brandt is trained to read the world around her, which at USC means understanding the context of the campus\u27 buildings — why they were built in a certain style, why they were named for particular individuals and how the institution defines its identity through its physical space. Today\u27s conversation with Dr. Brandt touches on those ideas and the university\u27s recent efforts to tell a larger story of its past through figurative monuments.https://scholarcommons.sc.edu/rememberingthedays/1096/thumbnail.jp

The Effects of Physical Exercise on Emotion Dysregulation in Postsecondary Students with and Without ADHD
No full textEmotion dysregulation is a common issue among college students with ADHD, and emotion dysregulation in adults with ADHD is associated with many negative outcomes including higher levels of psychological distress and social impairment, poorer functioning at school and work, greater symptoms of anxiety and depression, and lower quality of life. Past work suggests that physical exercise can be useful in treating core ADHD symptoms for children and adolescents with ADHD, but less is known about its effects for young adults with ADHD. Exercise has been shown to be effective in targeting emotion dysregulation among the general adult population. Some work has shown beneficial effects of exercise on cognitive functioning, internalizing symptoms, and core ADHD symptoms in college students with ADHD, but no work to our knowledge has investigated the effects of exercise on emotion dysregulation in college students with ADHD. The current study aimed to address this gap by testing the acute effects of physical exercise on emotion regulation among emerging adult postsecondary students with and without ADHD. We hypothesized that physical exercise would have a beneficial effect on emotion dysregulation for all participants compared to the non-exercise condition, but that the effect will be larger among participants with ADHD. Findings showed that the main effect of group was not significant, but there was a small effect size. Participants with ADHD reported more emotion dysregulation than participants without ADHD. The main effect of condition on emotion dysregulation was not significant, but there was a small effect. Participants reported lower levels of emotion dysregulation after exercise than non-exercise. The group x condition interaction effect was not significant, but there was a small effect such that participants without ADHD showed more improvement in emotion dysregulation following exercise than did participants with ADHD. Although the findings did not reach significance, the effect sizes show partial support for the hypotheses. Future work with a larger sample may be more adequately powered for detecting statistically significant results
Computational Screening and Experimental Validation of Promising Wadsley-Roth Niobates
No full textThe demand for efficient, high-capacity energy storage has driven research into the development of advanced materials for lithium-ion batteries, among which Wadsley–Roth (WR) niobates stand out due to rapid Li+diffusion within ReO3-like blocks (n × m × ∞) and good electronic conductivity along shear planes. Despite the remarkable features of WR phases, there are presently less than 30 known compounds which limits identification of structure–property relationships for improved performance as well as the identification of phases with more earth-abundant elements. In this work, we have dramatically expanded the set of potentially (meta)-stable compositions (with ΔHd\u3c 22 meV/atom) to 1301 (out of 3283) through high-throughput screening with density functional theory (DFT). This large space of compounds was generated through single- and double-site substitution into 10 known WR-niobate prototypes using 48 elements across the periodic table. To confirm the structure predictions, we successfully synthesized MoWNb24O66and validated it with X-ray diffraction. The measured lithium diffusivity in MoWNb24O66has a peak value of 1.0 × 10–16m2/s at 1.45 V vs Li/Li+and achieved 225 ± 1 mAh/g at 5C. Thus, a computationally predicted phase was realized experimentally with performance exceeding Nb16W5O55(a recently reported WR phase benchmark material). Overall, the computational data set of potentially stable compounds with one realized that has competitive performance provide a valuable guide for experimentalists toward discovering long-duration battery materials
Investigating Copper Doping in Lead Oxyapatite: Flux Growth of Copper-Containing Pb\u3csub\u3e10\u3c/sub\u3e (PO\u3csub\u3e4\u3c/sub\u3e)\u3csub\u3e6\u3c/sub\u3eO Single Crystals
No full textA flux growth method for the high-yield synthesis of Pb10(PO4)6O single crystals was developed. This optimized synthesis method was utilized for the systematic doping of copper into the lead apatite structure, where the availability of single crystals allowed for a detailed structural analysis via single crystal X-ray diffraction. Our developed synthesis method resulted in a different type of copper doping in lead apatite where instead of Cu(II) doping onto the lead sites, doping occurred via Cu(I) doping into the disordered channels at the center of the Pb(1)/Pb(2) columns in the form of CuO2 linear units. The presence of Cu(I) as opposed to Cu(II) in the structure was shown via magnetic susceptibility data which also indicated a lack of superconductivity in the modified lead apatite at all achieved doping levels. The knowledge gained from this study enabled a reanalysis of the initial diffraction data reported for LK-99. While this work further supports the lack of superconductivity in the modified lead apatites, it does allow us to suggest a more accurate formula for LK-99: Pb10(PO4)6(CuO)2O1-1.5x
Crystal Growth of Quaternary Rare Earth Selenosilicates by Using the Flux-Assisted Boron Chalcogen Mixture Method: Investigation of Their Magnetic and Optical Properties
No full textA series of rare earth magnesium selenosilicates, RE3Mg0.5SiSe7 (RE = Ce, Pr, Nd, Sm, Gd, Tb, Dy) were obtained as single crystal using the flux assisted boron chalcogen mixture (BCM) method. The structures of the crystals were determined by single-crystal X-ray diffraction. The RE3Mg0.5SiSe7 series crystallizes in the hexagonal crystal system in the space group P63. Polycrystalline powders were synthesized to perform physical property measurements. Magnetic measurements over the 2-300 K temperature range reveal that Ce3Mg0.5SiSe7 and Gd3Mg0.5SiSe7 exhibit paramagnetic behavior with negative Weiss constants (θW = −14.50, θW = −6.13 K, respectively). The optical properties of RE3Mg0.5SiSe7 (RE = Ce, Pr, Nd, Sm, Gd) were measured by ultraviolet-visible (UV-vis) diffuse reflectance. Density functional theory (DFT) electronic structure calculations were performed. A second harmonic generation measurement was performed on a polycrystalline powder of Ce3Mg0.5SiSe7 and was found to be SHG active with an efficiency of 0.11 times the standard potassium dihydrogen phosphate (KDP)
Stepping into Who I Fully Am: A Creative Exploration of Autistic Menopause
No full textResearch suggests that perimenopause can compound existing struggles for some Autistic people, with potentially catastrophic consequences. Barriers to self-expression due to communication differences are also well-documented. Acknowledging this, our neurodiverse research team invited creative submissions themed around Autistic experiences of menopause, receiving works from six Autistic participants including paintings, poetry, and graphic works. Engaging with the six creative submissions, Autistic Community Researchers on our team produced reflexive, polytextual response works. Creative exploration of Autistic menopause encouraged emotional catharsis, self-understanding, and activism/artivism. Autistic Community Researchers noted transcendent, almost “magical” dimensions of connecting with other Autistic people’s lived experiences. Our creative emancipatory approach enabled Autistic, multimedia responses which traditional research methods would not have elicited. To our knowledge, no other studies to date have used arts-based research to explore Autistic people’s experiences of menopause and inclusive research practices
The Complexity of Promoting Physical Activity in English State Primary Schools: An In-Depth Qualitative Analysis of the Role of Social Context
No full textBackground
Primary schools present an opportunity to equitably promote physical activity. To date, school-based interventions have had limited success. Contextual differences between schools could be a key factor that contributes to this lack of impact. However, the elements that constitute a school’s social context (i.e. the organisational, political, cultural, and sociodemographic characteristics) and how they might impact on primary school physical activity are unclear. The aims of this study were to conduct an in-depth qualitative analysis of state primary school social context related to physical activity and, using this analysis, provide recommendations for policy and practice. Methods
We conducted one-to-one semi-structured interviews with 33 state primary school staff in Southwest England between November 2023 and January 2024. Staff roles included headteachers/principals (n = 5), deputy headteachers/principals (n = 5), class teachers (n = 7), Physical Education (PE) subject leads (n = 8), dedicated PE teachers (n = 4), teaching assistants (n = 2), and one Parent Teacher Association chair. Staff were recruited from 19 purposively-sampled schools with a range of school sizes and sociodemographic characteristics. We used reflexive thematic analysis. Results
Five themes were generated that highlighted: (1) the impact of regulatory systems and curriculum pressures created an environment where physical activity was difficult to prioritise; (2) schools with high pupil needs experienced increased pressure, which sometimes impacted staff motivation and wellbeing; (3) senior leadership priorities were key to promoting pupil physical activity, influenced by their personal interests/background/values, regulatory inspections, curriculum pressures, and pupil needs; (4) limited PE training during teacher training impacted teacher confidence that, when combined with curriculum pressures, led many schools to outsource PE to external enterprise; and (5) “passionate” individual staff members who dedicated their own time were important to drive physical activity in the pressured school environment. Conclusion
Revisions to school regulatory systems and policies are needed to enable schools to prioritise physical activity so it is not dependent on “passionate” individuals. Senior leadership plays a key role in prioritising physical activity in the high pressure state primary school environment. It is important that practitioners and researchers consider these diverse and challenging social contextual factors within English state primary schools in intervention design

No full textAn Evaluation of a Multi-Level LGBTQ Bystander Intervention for College Athletics: A Pilot Study
No full textThis mixed methods pilot study explored the impact of a multi-level bystander intervention training for collegiate athletes, coaches, and athletic department staff. The trainings consisted of three components: 1) education about constructs relevant to being an ally to the LGBTQ community; 2) engagement in self-reflective activities to raise awareness and decrease the influence of prejudicial beliefs and biases about the LGBTQ community; and 3) training on preventative actions and bystander intervention strategies specific to stopping LGBTQ-related bias. Quantitative data were collected through online pretest and posttest surveys (prior to the intervention and 12 weeks following the intervention; N = 267 student athletes and N = 125 coaches and athletic department staff), as well as from formative evaluation surveys collected at the end of each training (N = 190 student athletes and N = 175 coaches and athletic department staff). The qualitative data were obtained through interviews with coaches, athletic department staff, and a student athlete (N =18). Based on repeated-measures t tests and thematic analysis, the results of this pilot study provide initial support for the use of such an intervention to improve the athletic department climate for LGBTQ student athletes and staff within the context of collegiate athletics
