12 Études Caractéristiques, Opus 2, by Adolf von Henselt: A Pedagogical Guide with Practical Exercises on Selected Etudes (open access)

12 Études Caractéristiques, Opus 2, by Adolf von Henselt: A Pedagogical Guide with Practical Exercises on Selected Etudes

Adolf von Henselt (1814–1889) was one of the most renowned German pianists and composers of his day. The majority of his compositions are for the piano, one of his most successful being the set of Piano Études, Op. 2. It consists of twelve etudes, each of which is designed for developing a particular technique. Henselt's etudes are as demanding as Chopin's and Liszt's, so this pedagogical guide is designed for advanced-level students. Henselt uses many finger extensions and stretches larger than an octave, which may be difficult for smaller hands to play, but proper flexibility and relaxation should enable all students to play them. This dissertation describes the specific technique for six selected etudes and provides exercises to help students learn each technique effectively. The selected etudes—Nos. 1, 2, 3, 6, 9, and 11—were chosen to cover all three technical levels of less-advanced, advanced, and very advanced as well as a variety of musical styles and technical challenges.

3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications (open access)

3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications

This study investigated a new approach to achieving high energy density supercapacitors (SCs) by using high surface area self-activated carbon from waste coffee grounds (WCGs) and modifying 3D printed electrodes' porous structure by varying infill density. The derived activated carbons' surface area, pore size, and pore volume were controlled by thermally treating the WCGs at different temperatures (1000˚C, 1100˚C, and 1200˚C) and post-treating with HCL to remove water-soluble ashes and contaminants that block activated carbon pores. Surface area characterization revealed that the carbon activated at 1000˚C had the highest surface of 1173.48 m2 g-1, and with the addition of HCL, the surface area increased to 1209.35 m2 g-1. This activated carbon was used for fabricating the electrodes based on the surface area and having both micropores and macropores, which are beneficial for charge storage. Direct ink writing (DIW) method was utilized for 3D printing SC electrodes and changing the electrode structure by increasing the infill densities at 30%, 50%, and 100%. Upon increasing the infill densities, the electrodes' mass increased linearly, porosity decreased, and the total surface area increased for the 30% and 50% infill electrodes but decreased for the 100% infill electrode.

Accessibility and Pedagogical Value in Virtuosic American Trombone Solo Literature: A Performance Guide to "Divertimento for Trombone and Band" (2012) by Jack Stamp (open access)

Accessibility and Pedagogical Value in Virtuosic American Trombone Solo Literature: A Performance Guide to "Divertimento for Trombone and Band" (2012) by Jack Stamp

This dissertation is an examination of Divertimento for Solo Trombone and Wind Band by renowned wind band composer and conductor Jack Stamp. The result of this study is the illumination of a 21st-century composition for solo trombone and band that is made accessible for future performers, accomplished by constructing original musical exercises that are influenced by current trombone pedagogical materials that have either been edited, annotated or created by current performers and pedagogues such as Joseph Alessi, Brad Edwards and Michael Mulcahy. The piece also incorporates 20th -century American wind band influences. The careful selection of pedagogical materials serves the purpose of making this challenging solo accessible for the advanced academic trombonist and can serve as a template for surveying advanced literature of the present and future. Additionally, the pedagogical materials selected for use in this dissertation were considered based on their value in the present academic trombone repertory. Thus, this performance guide reflects on the validity of the modern trombone pedagogical literature to guide a performer's study, interpretation, and performance of a 21st-century work for solo trombone.

Acute and Sublethal Impacts of Crude Oil Photo-Induced Toxicity in an Early Life Stage Marine Fish (Sciaenops ocellatus) and Invertebrate (Americamysis bahia)

We investigated the modifying effects of ultraviolet (UV) light and chemical dispersant (Corexit 9500A) on crude oil toxicity in juvenile mysids (≤ 24 h) (Americamysis bahia) and larval red drum (24-72 hpf) (Sciaenops ocellatus). These results demonstrate that crude oil toxicity significantly increases with co-exposure to environmentally relevant UV levels in both species, indicating photo-induced toxicity. This toxicity was further exacerbated by the application of chemical dispersants which increased the dissolution and concentration of oil-derived polycyclic aromatic hydrocarbons (PAHs) in test solutions. To better understand the mechanisms and initiating events of this observed photo-induced toxicity, the incidence of apoptotic cell death and global transcriptomic changes were assessed in larval red drum (24-72 hpf) following co-exposure to crude oil and UV. These results showed that co-exposure to UV and low concentrations of crude oil (<1 µg/L ∑PAH50) induced apoptotic cell death in skin and eye tissue and altered transcriptomic pathways related to visual processing and dermatological disease. To link these cellular and molecular impacts of photo-induced toxicity to apical endpoints of ecological performance, sublethal impacts to growth, metabolic rate, and visually mediated behaviors were explored in larval red drum at 2 developmental stages. These results suggested that earlier life stages may …

Additive Friction Stir Deposition of Al-Ce Alloys for Improved Strength and Ductility

Additive friction stir deposition (AFSD) is a solid-state additive manufacturing (AM) technique that breaks down large constituent particles into more refined and uniformly disturbed microstructure. AFSD was used to print Al-Ce alloys. Current commercial Al-alloys upon elevated temperatures go through dissolution and coarsening of strengthening precipitates causing mechanical degradation of these alloys. Al-Ce alloys do not have this issue as cerium's low solubility restricts dissolution into the aluminum matrix at elevated temperatures, thus giving great thermal stability to the microstructure. Al-Ce alloys lack solid solubility that affects the solid solution strengthening and precipitation strengthening. Al-Ce alloys have limitation at room temperature as they can only reach a maximum of ~65 MPa yield strength. Elements like magnesium have been added to alloy to enable solid solution strengthening, and scandium to enable precipitation strengthening to improve strength before going through the AFSD process. By adding new elements to the Al-Ce alloys, an increase in the yield strength from ~60 MPa to ~200 MPa was achieved before AFSD. The casted alloys form coarse particles that reach 300 µm in size; resulting in stress concentration that causes material fracture before necking, giving >10% ductility. AFSD breaks down these coarse particles to increase strength and …

Adoption of Innovation in a Community College Environment: User Perceptions of Virtual Reality (VR) Technology among Students Studying Emergency Medical Service (EMS) (open access)

Adoption of Innovation in a Community College Environment: User Perceptions of Virtual Reality (VR) Technology among Students Studying Emergency Medical Service (EMS)

This research study examined the implementation of an extended reality (XR) lab on a community college campus to facilitate student and faculty access to immersive learning resources. The study, conducted during one skills day, involved 46 students and was designed to understand if integrating immersive VR into emergency medical technician (EMT) education could enhance learner confidence and motivation, develop problem-solving and analytical thinking skills, and thus connecting the classroom learning with real-world application. The majority of participants reported increased motivation and engagement, alongside improvements in learning outcomes like knowledge retention and skill development. Applying the unified theory of acceptance and use of technology (UTAUT) model revealed performance expectancy, effort expectancy, social influence, and facilitating conditions as key determinants of VR adoption in EMT education. While no significant overall performance enhancement was observed, VR training showed potential to boost motivation, confidence, and specific performance aspects. Furthermore, student perceptions towards VR in EMT education were largely positive, thereby suggesting its utility in immersive scenario training, skill acquisition in a risk-free environment, enhancing learner engagement, and real-world situational preparedness. VR demonstrated promise as a transformative tool in EMT education, necessitating further research to fully exploit its potential in diverse learning environments.

Adult Attachment, Racial-Ethnic Identity, Racial-Ethnic Socialization, and Subjective Wellbeing

The current study aimed to explore the direct effect of insecure adult attachment on subjective wellbeing and its indirect effect via racial-ethnic identity. Additionally, the present study examined the extent to which racial-ethnic socialization practices may moderate adult attachment and racial-ethnic identity link. The final sample included 213 emerging adults (M = 20.94; SD = 2.96) with diverse racial-ethnic backgrounds. PROCESS Model 4 and 1 were used to examine the direct and indirect effect of insecure attachment on subjective wellbeing via racial-ethnic identity variables and the interaction effect between insecure attachment and racial-ethnic socialization on racial-ethnic identity variables. Results indicated the direct effect of insecure attachment on subjective wellbeing but did not support hypotheses for the indirect effect of insecure attachment on subjective wellbeing via the racial-ethnic identity variables. Additionally, results indicated that overt socialization buffered the negative impact of attachment avoidance on racial-ethnic identity exploration. Furthermore, racial-ethnic identity variables and subjective wellbeing significantly differed across racial-ethnic groups and socioeconomic statuses. Findings provide insight on the distinct concepts of attachment and racial-ethnic identity as they highlight inter- and intra-personal components, respectively. Mental health professionals may utilize overt socialization to help clients develop a sense of purpose and meaning related to …
