    Within the occupational therapy (OT) profession, the collaborative fieldwork supervision model is considered a non-traditional approach to fieldwork education. Although supportive strategies for fieldwork education have been developed, there is little data to validate fieldwork educators\u27 perspectives on the value and helpfulness of these supports for this model. Using a mixed-methods research design, this study aimed to identify what supports influenced fieldwork educators to use the collaborative fieldwork supervision model, what supports are valued when implementing it, and what supports would be considered helpful for those who have not used it. A total of 382 fieldwork educators completed the study, with 113 who identified as model users and 269 who identified as model non-users. Four themes emerged from model users that influenced their decision to use the model: support from 1) fieldwork site context, 2) academic program, 3) student engagement, and 4) professional resources. Based on the study results, a four-part approach is recommended for educational programs to support the initiation and use of the collaborative fieldwork supervision model

    An online survey was conducted of 225 occupational therapy (OT) practitioners living in the rural states of North Dakota and Wyoming to explore practice patterns and the influence of the college experience on employment choice. Findings showed that rural practitioners had greater variability of hours spent working (5.5 more hours per week, p=.028), and one more work location on average (p=.006). Therapists in urban settings spent 15% more time in fieldwork education than their rural counterparts (p=.021). Rural practice choice was influenced by participation in Level I and Level II fieldwork (p=.002) but not by loan debt. Study implications for academic programs include focusing on multiple areas of practice in the curriculum design, and exposure of students to rural practitioners and rural practice examples/experiences. Recommendations were made for rural fieldwork educator training and employer support of rural fieldwork education. Further study of the experience of working within a rural practice context as a student and OT practitioner are recommended, including variables impacting rural practitioner work with fieldwork students, and student interest in rural fieldwork placement

    Level II Fieldwork Educators\u27 Perceived and Experienced Challenges with Using the Collaborative Fieldwork Supervision Model

    Get PDF
    Fieldwork shortages have been noted in the literature for some time. With the ever-changing healthcare system and an increasing number of students in occupational therapy programs, the scarcity of fieldwork placements is dire. Rooted in adult learning principles, the collaborative fieldwork supervision model is one approach to fieldwork education that may alleviate the shortage of placements, while also supporting student learning. This model is designed to have one fieldwork educator supervising two or more students throughout a fieldwork experience. The strengths and challenges of this model are well documented, although it is unclear if the identified challenges are the same or different for those who have and have not used the model. Therefore, a research study was conducted to investigate Level II fieldwork educators’ experienced and perceived challenges of the collaborative fieldwork supervision model. Narrative data was gathered from both fieldwork educators who have used the model and those who have not used the model, within the last five years. The researchers investigated two open-ended questions from a nationwide survey disseminated in 2018. Nearly 30% of the study respondents reported having used the model, while 70% reported not using the model. The same five themes emerged from both groups, however, the prevalence and subthemes between the two groups were different. The themes are: 1) considerations at fieldwork site; 2) knowledge, skill, and professionalism of students; 3) client needs and level of comfort; 4) fieldwork educator knowledge and familiarity with model; and 5) culture of fieldwork education. Methods for addressing challenges and implications for occupational therapy education are discussed

    Mapping Review of Fieldwork Education Literature

    Fieldwork is an integral phase of occupational therapy education, bolstered by a small but growing evidence base. A broad understanding of the state of that evidence base is necessary to inform the directions for future growth. The purpose of this work was to establish the current state of occupational therapy fieldwork literature, map that literature to recognized criteria for educational research, and identify gaps in the existing literature. Authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to conduct a mapping review of articles with a primary focus on fieldwork education of occupational therapy (OT) or occupational therapy assistant (OTA) students in United States (Accreditation for Occupational Therapy Education)-based programs. Mapping criteria included level of education [OT, OTA], level of fieldwork [Level I, Level II], and categories of the AOTA Education Research Agenda - Revised (2018). Sources included four databases (Academic Search Premier, CINAHL, ERIC, PubMed) and one additional journal (Journal of Occupational Therapy Education). A total of 1,619 articles were identified, with 67 articles meeting inclusion criteria. The 67 included articles disproportionately focused on Level II OT fieldwork (53%, n=36), with sparse representation of Level I OTA fieldwork (1.5%, n=1), and addressed only two categories of the Education Research Agenda (2018; 80%, n=54). Level I fieldwork, occupational therapy assistant programs, and large swaths of the association’s Education Research Agenda (2018) were dramatically (or completely) underrepresented in fieldwork education research, suggesting important priorities for the immediate future of occupational therapy fieldwork education

    Seismic isolation and suspension systems for advanced LIGO

    To meet the overall isolation and alignment requirements for the optics in Advanced LIGO, the planned upgrade to LIGO, the US laser interferometric gravitational wave observatory, we are developing three sub-systems: a hydraulic external pre-isolator for low frequency alignment and control, a two-stage active isolation platform designed to give a factor of ∼1000 attenuation at 10 Hz, and a multiple pendulum suspension system that provides passive isolation above a few hertz. The hydraulic stage uses laminar-flow quiet hydraulic actuators with millimeter range, and provides isolation and alignment for the optics payload below 10 Hz, including correction for measured Earth tides and the microseism. This stage supports the in-vacuum two-stage active isolation platform, which reduces vibration using force feedback from inertial sensor signals in six degrees of freedom. The platform provides a quiet, controlled structure to mount the suspension system. This latter system has been developed from the triple pendulum suspension used in GEO 600, the German/UK gravitational wave detector. To meet the more stringent noise levels required in Advanced LIGO, the baseline design for the most sensitive optics calls for a quadruple pendulum, whose final stage consists of a 40 kg sapphire mirror suspended on fused silica ribbons to reduce suspension thermal noise

    Seismic isolation of Advanced LIGO: Review of strategy, instrumentation and performance

    Get PDF
    The new generation of gravitational waves detectors require unprecedented levels of isolation from seismic noise. This article reviews the seismic isolation strategy and instrumentation developed for the Advanced LIGO observatories. It summarizes over a decade of research on active inertial isolation and shows the performance recently achieved at the Advanced LIGO observatories. The paper emphasizes the scientific and technical challenges of this endeavor and how they have been addressed. An overview of the isolation strategy is given. It combines multiple layers of passive and active inertial isolation to provide suitable rejection of seismic noise at all frequencies. A detailed presentation of the three active platforms that have been developed is given. They are the hydraulic pre-isolator, the single-stage internal isolator and the two-stage internal isolator. The architecture, instrumentation, control scheme and isolation results are presented for each of the three systems. Results show that the seismic isolation sub-system meets Advanced LIGO\u27s stringent requirements and robustly supports the operation of the two detectors

    Advanced LIGO two-stage twelve-axis vibration isolation and positioning platform. Part 2: Experimental investigation and tests results

    Get PDF
    This paper presents the results of the past seven years of experimental investigation and testing done on the two-stage twelve-axis vibration isolation platform for Advanced LIGO gravity waves observatories. This five-ton two-and-half-meter wide system supports more than a 1000 kg of very sensitive equipment. It provides positioning capability and seismic isolation in all directions of translation and rotation. To meet the very stringent requirements of Advanced LIGO, the system must provide more than three orders of magnitude of isolation over a very large bandwidth. It must bring the motion below 10-11 m/Hz at 1 Hz and 10-12 m/Hz at 10 Hz. A prototype of this system has been built in 2006. It has been extensively tested and analyzed during the following two years. This paper shows how the experimental results obtained with the prototype were used to engineer the final design. It highlights how the engineering solutions implemented not only improved the isolation performance but also greatly simplified the assembly, testing, and commissioning process. During the past two years, five units have been constructed, tested, installed and commissioned at each of the two LIGO observatories. Five other units are being built for an upcoming third observatory. The test results presented show that the system meets the motion requirements, and reach the sensor noise in the control bandwidth

    New generations of gravity wave detectors require unprecedented levels of vibration isolation. This paper presents the final design of the vibration isolation and positioning platform used in Advanced LIGO to support the interferometer\u27s core optics. This five-ton two-and-half-m wide system operating in ultra-high vacuum. It features two stages of isolation mounted in series. The stages are imbricated to reduce the overall height. Each stage provides isolation in all directions of translation and rotation. The system is instrumented with a unique combination of low noise relative and inertial sensors. The active control provides isolation from 0.1 Hz to 30 Hz. It brings the platform motion down to 10-11m/√Hz at 1 Hz. Active and passive isolation combine to bring the platform motion below 10-12m/√Hz at 10 Hz. The passive isolation lowers the motion below 10-13m/√Hz at 100 Hz. The paper describes how the platform has been engineered not only to meet the isolation requirements, but also to permit the construction, testing, and commissioning process of the fifteen units needed for Advanced LIGO observatories
