Mapping the Traits Desired in Followers and Leaders onto Fundamental Dimensions of Social Evaluation
We applied the social evaluation framework to investigate the traits desired in an “ideal” follower, which were compared to the traits desired in an “ideal” leader. Across three studies and five samples, both differences and similarities in role-specific preferences mapped onto the Vertical-Horizontal dimensions of the social evaluation framework in ways that aligned with the demands of each role. Traits higher on the Horizontal-morality facet (e.g., cooperative, dutiful) and lower on the Vertical-assertiveness facet (e.g., confident, ambitious) differentiated ideal follower preferences from ideal leader preferences. Focusing on the traits most strongly desired in relation to each role, traits that supported social coordination and collective goal attainment (i.e., work ethic, cooperativeness) were prioritized in relation to ideal followers, whereas intelligence was prioritized for ideal leaders. Trustworthiness was equally valued across both roles. Moreover, we differentiated between necessary and luxury traits by adjusting the budget individuals could allocate towards the desired traits. Investments in necessary versus luxury traits further supported the social evaluation framework and highlighted the need to account for the facet-level distinctions within the Vertical (assertiveness, ability) and Horizontal (morality, friendliness) dimensions. Further, these findings were found to be robust across manipulations (e.g., the target’s gender and hierarchical level)
Advancing On-Orbit Assembly With ISAR
The U.S. Naval Academy (USNA) is looking to advance autonomous assembly with a next-generation Intelligent Space Assembly Robot (ISAR) system, which seeks to demonstrate semi-autonomous robotic assembly capabilities on orbit. ISAR is a small size form, low cost, 3U CubeSat-class satellite intending to mature robotic assembly capabilities. It is comprised of two key subsystems: twin 60 cm seven degree of freedom robotic arms, RSat, and the sensors which utilize one 3D camera and two 2D cameras to increase spatial awareness and aid real-time responsible maneuvering in a dynamic space environment. RSat, developed by the Naval Academy, is an existing set of robotic arms housed in a 3U CubeSat. RSat serves as the foundation for the next-generation ISAR program and will be launched as a free-flyer mission in 2018 as part of NASA\u27s ElaNa XIX launch. On-orbit demonstrations of ISAR will test the ability to perform a test structure assembly with robotic arm actuation at a fraction of size and cost of previous space robotic platforms. This paper will present an overview of the ISAR system, outline design, operation, and demonstration modifications for the on orbit experiment and present a novel concept for autonomous operations
Influencia del ladrillo lark triturado como agregado grueso para mejorar la resistencia a la compresión del concreto
El siguiente trabajo de investigación surge a partir de la necesidad de buscar posibles soluciones técnicas y económicas en conseguir e inclusive mejorar levemente la resistencia a la compresión del concreto requerido, donde la metodología usada consistió en reemplazar parte del agregado grueso pétreo por ladrillo Lark triturado en el diseño de mezcla del concreto, usando el método comité ACI 211.1-91, que es la más usada en nuestro país. Se reemplazó parte del agregado grueso pétreo por ladrillo Lark triturado en cantidades del 25%, 30%, y 50% en volumen, donde se tomó en cuenta el triturado del ladrillo Lark tanto manualmente como a trituradora en tamaños de partículas de 3/4 a 1/2 pulgadas respectivamente, para luego ser comparadas con el diseño de mezcla de concreto estándar sin incorporación de ladrillo, con una resistencia a la compresión de diseño de 210 Kg/cm². Los resultados muestran que no es recomendable el reemplazo debido a que minora la resistencia a la compresión del concreto, en cantidades de reemplazo del 30% en volumen como máximo, la resistencia disminuye aproximadamente en un 10% de la resistencia de diseño (210 Kg/cm²), y para reemplazos mayores del 30% en volumen la resistencia a la compresión disminuye considerablemente a más del 10% de la resistencia requerida (210 Kg/cm²) en un concreto estándar. La conclusión del siguiente trabajo de investigación sugiere no reemplazar parte del agregado grueso pétreo por ladrillo Lark triturado con el propósito de llegar o mejorar levemente la resistencia a la compresión del concreto requerido
Genomic Data Analysis of SARS-Cov-2 Variants and Trends
The objective of this study was to analyze SARS-Cov-2 sequence variants and trends during the pandemic. This study was done using SARS-Cov-2 positive patient samples from Boise State University and the surrounding community. For variant analysis, Next Generation Sequencing was performed and the sequences were analyzed using the DRAGEN COVID Lineage (version 3s) pipeline on Illumina’s BaceSpace software. Any sequences with low-quality control were removed from the data. Some of the factors that were analyzed included symptoms by clade, campus positivity rates and the amount of campus and community tests run each semester. Individuals from the Boise State campus were identified as off-campus students, on-campus students, or faculty/staff members. The COVID sequencing data was also analyzed against key demographics such as an individual’s gender, age, race, ethnicity, and location. Sequences were also organized by the phylogeny of clades found from 2020-2024
Tendon Rupture and Tendonitis in Low-Profile Dorsal versus Volar Plating for Distal Radius Fractures: A Systematic Review and Meta-Analysis
Tendon Rupture and Tendonitis in Low-Profile Dorsal versus Volar Plating for Distal Radius Fractures: A Systematic Review and Meta-Analysis
Background: Dorsal plating of distal radius fractures has historically been associated with high rates of hardware removal, tendonitis, and tendon rupture. Newer generation low-profile dorsal plates are thinner (\u3c1.6mm thick) with improved characteristics. We examine whether low-profile dorsal plates still have higher rates of tendon complications than volar locking plates.
Methods: We searched Ovid MEDLINE, Web of Science, and EMBASE for published literature describing tendon complications in association with plating of distal radius fractures. Inclusion criteria encompasses any primary study of low-profile dorsal plates that included data on tendon complications. Studies that included both low-profile dorsal and volar plating arms were included in the meta-analysis.
Results: Nine studies were selected for inclusion. All studies were retrospective cohorts or case series with a total of 446 low-profile dorsal plates. Five studies were included in the meta-analysis with a total of 806 subjects; 584 received volar plates and 222 received low-profile dorsal plates. Meta-analysis showed no significant difference in rates of tendonitis or tendon rupture.
Discussion: The included studies were all of level III or IV evidence. To our knowledge, this review provides the largest comparison of low-profile dorsal and volar locked distal radius plates to date. Pooled analysis results provide further comparison of low-profile dorsal versus volar plating

Effectiveness of insecticides, physical barriers and size of planting stock against damage by the pine weevil (Hylobius abietis)
A series of five trials was established in Great Britain to test the effectiveness of fourteen treatments and a control on reducing mortality and damage by pine weevil (Hylobius abietis) on recently replanted Sitka spruce (Picea sitchensis). Overall percentage mortality and damage was significantly different between trials, varying from a median of 24%–100%. The most effective treatments in reducing mortality were insecticides and physical barriers, with insecticides being most cost effective. Low volume applications of insecticides were found to be as effective as higher doses. Using larger trees did not reduce mortality compared to the control, nor did application of a controlled release fertiliser. At Auchencairn, the trial where mortality was highest no treatment provided protection and so there is a need to develop an effective and integrated approach to reducing damage by pine weevil
