Employing Service Learning to Promote Student Self-Efficacy in Occupational Therapy Education

A study was conducted to evaluate student participation in a community-based service learning experience offered in the Masters of Occupational Therapy (OT) Program at the University of St. Augustine for Health Sciences (USAHS) to identify how students’ perceptions of their self-efficacy change after they participate in a service-learning experience. A mixed methods case study approach was used to evaluate student’s perceptions of self efficacy and identify characteristics of the service learning experience that contribute to improved perceived self-efficacy. A paired samples t test was conducted to compare student confidence levels before and after participation in the service learning project. The analysis of total scores indicates an improvement in confidence after participation in the experiential learning activities offered on each campus. There was a significant difference in the total scores for pretest (M= 460, SD= 64.4) and posttest (M=526, SD= 54.7) in student confidence levels (t(55)=-9.6, p=.000). Qualitative data indicated that it was the interaction of the prerequisite conditions that created the optimal opportunity for growth and improvement of self-confidence. It is when these opportunities are presented that the development of professional characteristics is facilitated. Through carefully facilitated experiences, and subsequent enhanced professional characteristic development the students then develop core professional attributes. Collectively, the development of these core professional attributes contributes to a greater sense of self-efficacy and improved clinical reasoning for participants. The results of this study were used to construct an emerging educational model that can be used to design educational experiences that will facilitate the 5 development of professional self-efficacy and improved clinical reasoning in occupational therapy students. It is proposed that the model presented can support occupational therapy educators in the development of curricular experiences that will better support the development of clinical reasoning for occupational therapy students. By emphasizing the development of professional self-efficacy in occupational therapy students, educators can support and maintain the use of occupation as a central philosophy and core value of our profession. By supporting the development of core professional attributes early in education, faculty can support the development of future practitioners who will maintain the use of occupation as the core of our profession, and will ensure that future occupational therapists do continue to use occupation as central to their practice

Thinking and Acting Outside the Box

Role play and simulation are both powerful teaching tools that have been used in nursing and physician education for many years. Role playing offers a cheaper alternative than simulation and allows the individuals playing the roles to experience the patient’s perspective. The University of St. Augustine in California is one of the few PT programs to teach PT students the Allen Cognitive levels, and the importance of cognition when planning and developing interventions. With the aging of the baby boomers, more therapists will be working with the aging population, and it is critical that the concept of cognitive challenges is introduced, and practiced, within the professional educational setting. The university also strongly supports inter-professional education and its growing role in health education.https://soar.usa.edu/casmsummer2018/1000/thumbnail.jp

Elementary structural building blocks encountered in silicon surface reconstructions

Driven by the reduction of dangling bonds and the minimization of surface stress, reconstruction of silicon surfaces leads to a striking diversity of outcomes. Despite this variety even very elaborate structures are generally comprised of a small number of structural building blocks. We here identify important elementary building blocks and discuss their integration into the structural models as well as their impact on the electronic structure of the surface

Superstructure-induced splitting of Dirac cones in silicene

Atomic scale engineering of two-dimensional materials could create devices with rich physical and chemical properties. External periodic potentials can enable the manipulation of the electronic band structures of materials. A prototypical system is 3x3-silicene/Ag(111), which has substrate-induced periodic modulations. Recent angle-resolved photoemission spectroscopy measurements revealed six Dirac cone pairs at the Brillouin zone boundary of Ag(111), but their origin remains unclear [Proc. Natl. Acad. Sci. USA 113, 14656 (2016)]. We used linear dichroism angle-resolved photoemission spectroscopy, the tight-binding model, and first-principles calculations to reveal that these Dirac cones mainly derive from the original cones at the K (K') points of free-standing silicene. The Dirac cones of free-standing silicene are split by external periodic potentials that originate from the substrate-overlayer interaction. Our results not only confirm the origin of the Dirac cones in the 3x3-silicene/Ag(111) system, but also provide a powerful route to manipulate the electronic structures of two-dimensional materials.Comment: 6 pages, 3 figure

Spontaneous exciton condensation in 1T-TiSe2: a BCS-like approach

Recently strong evidence has been found in favor of a BCS-like condensation of excitons in 1\textit{T}-TiSe$_2$. Theoretical photoemission intensity maps have been generated by the spectral function calculated within the excitonic condensate phase model and set against experimental angle-resolved photoemission spectroscopy data. Here, the calculations in the framework of this model are presented in detail. They represent an extension of the original excitonic insulator phase model of J\'erome \textit{et al.} [Phys. Rev. {\bf 158}, 462 (1967)] to three dimensional and anisotropic band dispersions. A detailed analysis of its properties and further comparison with experiment are also discussedComment: Submitted to PRB, 11 pages, 7 figure

Influence of elastic scattering on the measurement of core-level binding energy dispersion in X-ray photoemission spectroscopy

We explore the interplay between the elastic scattering of photoelectrons and the surface core level shifts with regard to the determination of core level binding energies in Au(111) and Cu3Au(100). We find that an artificial shift is created in the binding energies of the Au 4f core levels, that exhibits a dependence on the emission angle, as well as on the spectral intensity of the core level emission itself. Using a simple model, we are able to reproduce the angular dependence of the shift and relate it to the anisotropy in the electron emission from the bulk layers. Our results demonstrate that interpretation of variation of the binding energy of core-levels should be conducted with great care and must take into account the possible influence of artificial shifts induced by elastic scatterin

Temperature dependent photoemission on 1T-TiSe2: Interpretation within the exciton condensate phase model

The charge density wave phase transition of 1T-TiSe2 is studied by angle-resolved photoemission over a wide temperature range. An important chemical potential shift which strongly evolves with temperature is evidenced. In the framework of the exciton condensate phase, the detailed temperature dependence of the associated order parameter is extracted. Having a mean-field-like behaviour at low temperature, it exhibits a non-zero value above the transition, interpreted as the signature of strong excitonic fluctuations, reminiscent of the pseudo-gap phase of high temperature superconductors. Integrated intensity around the Fermi level is found to display a trend similar to the measured resistivity and is discussed within the model.Comment: 8 pages, 6 figure

Applications for ultimate spatial resolution in LASER based μ\mu-ARPES: A FeSe case study

Combining Angle resolved photoelectron spectroscopy (ARPES) and a $\mu$-focused Laser, we have performed scanning ARPES microscopy measurements of the domain population within the nematic phase of FeSe single crystals. We are able to demonstrate a variation of the domain population density on a scale of a few 10 $\mu$m while constraining the upper limit of the single domain size to less than 5 $\mu m$. This experiment serves as a demonstration of how combining the advantages of high resolution Laser ARPES and an ultimate control over the spatial dimension can improve investigations of materials by reducing the cross contamination of spectral features of different domains
