Development And Validation Of A Basic Ground Skills Assessment For Equine-Assisted Services, Sarah J. Andersen Dec 2021

Development And Validation Of A Basic Ground Skills Assessment For Equine-Assisted Services, Sarah J. Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The equine-assisted services program at Utah State University produced and validated an assessment process used to test equines for suitability for equine-assisted services. Equine-assisted services incorporate the interaction of humans who face mental, physical, emotional, and/or social challenges and equines for therapeutic purposes. Recreational, physical, mental, social, and/or emotional goals are met through various equine-assisted services such as therapies, equine-assisted learning, and horsemanship.

Due to the potential for human injury while interacting with equines, it is important to ensure equines are assessed for safe behavior prior to participation in equine-assisted services. This is why our group developed and tested the …


Measuring Numeracy: Validity And The Programme For The International Assessment Of Adult Competencies (Piaac), Samuel L. Tunstall Jul 2020

Measuring Numeracy: Validity And The Programme For The International Assessment Of Adult Competencies (Piaac), Samuel L. Tunstall

Numeracy

A tension raised in recent scholarship is that between numeracy as a social practice and numeracy as a functional skill set. Such frameworks for conceptualizing numeracy pose a challenge to assessment because what individuals do with numeracy is not the same as what individuals can do (or express) in an assessment setting. This study builds on work related to numeracy assessment through a validity examination of a portion of a well-known assessment: the OECD’s Programme for the International Assessment of Adult Competencies (PIAAC). In following a path set out by standards for assessment, I ask: What does the PIAAC numeracy …

Organisational-Level Assessment Of Cloud Computing Adoption: Evidence From The Australian Smes, Salim Al Isma'ili, Mengxiang Li, Jun Shen, Pu Huang, Qiang He, Wu Zhan

Faculty of Engineering and Information Sciences - Papers: Part B

Cloud Computing (CC) is an emerging technology that can potentially revolutionise the application and delivery of IT. There has been little research, however, into the adoption of CC in Small and Medium-Sized Enterprises (SMEs). The indicators show that CC has been adopted very slowly. There is also a significant research gap in the investigation of the adoption of this innovation in SMEs. This article explores how the adoption of CC in Australia is related to technological factors, risk factors, and environmental factors. The study provides useful insights that can be utilised practically by SMEs, policymakers, and cloud vendors.


A Framework For Building Assessment And Learning Tools For Digital Skills, Ann Ciesla Jan 2020

A Framework For Building Assessment And Learning Tools For Digital Skills, Ann Ciesla

Dissertations, Master's Theses and Master's Reports

Technology continues to intertwine with aspects of our everyday lives, requiring a new set of skills in exploring and experimenting with user interfaces. For those who grow up and keep up with technology, these skills are second nature. But for those who do not, such as older adults, these skills can be hard to master. User interfaces are changing regularly, and it is no longer suffices to teach older adults how to solve a specific problem on a specific interface. The knowledge they gain is insubstantial because it does not help when the technology changes. They no longer understand how …

This cross-sectional survey study was conducted to determine if California community colleges designated as Hispanic Serving Institutions (HSIs) assess incoming students for basic computer skills, provide learning support for these skills, as well as assess the attitude of administrators towards basic computer skills of incoming students. Prior published research documented the false assumption in higher education incoming students are “digital natives”, capable of effectively using technology expected on college campuses; however, there was no research focused on community colleges designated as HSIs. The study adds to the body of literature about the assessment of and support for basic computer skills …


Towards An Assessment Framework Of Reuse: A Knowledge Level Analysis Approach, Ghassan Beydoun, Achim Hoffmann, Rafael Valencia-Garcia, Jun Shen, Asifqumer Gill Jan 2019

Towards An Assessment Framework Of Reuse: A Knowledge Level Analysis Approach, Ghassan Beydoun, Achim Hoffmann, Rafael Valencia-Garcia, Jun Shen, Asifqumer Gill

Faculty of Engineering and Information Sciences - Papers: Part B

The process of assessing the suitability of reuse of a software component is complex. Indeed, software systems are typically developed as an assembly of existing components. The complexity of the assessment process is due to lack of clarity on how to compare the cost of adaptation of an existing component versus the cost of developing it from scratch. Indeed, often pursuit of reuse can lead to excessive rework and adaptation, or developing suites of components that often get neglected. This paper is an important step towards modelling the complex reuse assessment process. To assess the success factors that can underpin …

Applying A Universal Design Approach To Empower Children With Multiple Impairments In Assistive Technology Assessment, Trish Mackeogh, Karola Dillenburg, John Donovan

Other

Rapid developments in technology, coinciding with the shift in educational ideology towards the inclusion of children with multiple disabilities, has led to increased calls for a Universal Design (UD) approach to promoting, user-friendly, proactive, transparent, and accessible environments and to the importance of Assistive Technology (AT) applications. For children with disabilities, technologies provide opportunities for greater and more flexible access to activities then traditional interfaces if applied and matched successfully. Relatively high abandonment rates of assistive technology have been documented, often due to a lack of user involvement in the assessment process. The field of Universal Design is showing that …

Compressive Behaviour Of Partially Frp Confined Concrete: Experimental Observations And Assessment Of The Stress-Strain Models, Weiqiang Wang, M Neaz Sheikh, Ali Qasim Al-Baali, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

This study provides new insight on the compressive behaviour of partially fibre reinforced polymer (FRP) confined concrete with either strain-hardening or strain-softening responses. Fully FRP confined concrete, partially FRP confined concrete with different strip gaps, and unconfined concrete were tested under axial compression. Four types of axial load-axial deformation behaviours were observed for specimens with different strip gaps. Even though a high volumetric ratio of FRP was applied, the confinement effectiveness was negligible when the strip gap exceeded the diameter of the specimens. Moreover, the axial stress-axial strain behaviours of wrapped and non-wrapped concrete were observed to be different, and …

Faculty of Engineering and Information Sciences - Papers: Part B

Purpose

The challenges of accurate dosimetry for stereotactic radiotherapy (SRT) with small unflattened radiation fields have been widely reported in the literature. In this case, suitable dosimeters would have to offer a submillimeter spatial resolution. The CyberKnife® (Accuray Inc., Sunnyvale, CA, USA) is an SRT‐dedicated linear accelerator (linac), which can deliver treatments with submillimeter positional accuracy using circular fields. Beams are delivered with the desired field size using fixed cones, the InCise™ multileaf collimator or a dynamic variable‐aperture Iris™ collimator. The latter, allowing for field sizes to be varied during treatment delivery, has the potential to decrease treatment time, …

Field Assessment Of Ballasted Railroads Using Geosynthetics And Shock Mats, Sanjay Nimbalkar, Buddhima Indraratna Jan 2016

Field Assessment Of Ballasted Railroads Using Geosynthetics And Shock Mats, Sanjay Nimbalkar, Buddhima Indraratna

Faculty of Engineering and Information Sciences - Papers: Part A

The ballasted railroads form an integral part of the modern transportation infrastructure in Australia. However, they are subjected to large stresses especially on mixed traffic lines, where heavy freight trains are operated. Under such adverse operational conditions, ballast progressively degrades contributing to overall track deformations and frequent maintenance. Maintaining geometry of ballast embankments is necessary to improve safety and efficiency of railway operations. The use of artificial inclusions (geosynthetics and shock mats) as well as recycled (discarded) ballast in track can be economically viable options. In order to gain more insight, the CGRE has conducted extensive field trials on two …

Assessment Of Interface Shear Behaviour Of Sub-Ballast With Geosynthetics By Large-Scale Direct Shear Test, Mohammad Mahdi Biabani, Buddhima Indraratna, Sanjay Nimbalkar

Faculty of Engineering and Information Sciences - Papers: Part A

A series of large-scale direct shear test were conducted to study the interface shear strength of subballast reinforced with different types of geomembranes and geogrids. The impact of normal stress (σn), shearing rate (SR), relative density (DR) and open area (OA%) on the behaviour of granular material was investigated in unreinforced and reinforced condition. The results revealed that the performance of material was markedly influenced by σn and OA. The results also showed that geogrids provided a greater value of passive resistance owing to have transverse ribs, but the mobilised passive resistance became smaller with increase in OA. The triaxial …

From Stem To Steam: Reframing What It Means To Learn, Nicole M. Radziwill, Morgan C. Benton, Cassidy Moellers Sep 2015

From Stem To Steam: Reframing What It Means To Learn, Nicole M. Radziwill, Morgan C. Benton, Cassidy Moellers

The STEAM Journal

Although involvement in art and design have been shown to play an essential role in catalyzing STEM research, true integration is still an area of active research. The realization of STEM education via STEAM lends itself to interactive and participatory dialogic art; this juncture provides a nonjudgmental space to cultivate the question-making aspect of inquiry, the ability to comfortably hold uncertainty, and a sensitivity to the process of discovery. Even though STEM education can (and often is) inquiry-based, assessments still tend to focus on whether knowledge or skills have been obtained, and this is no different than the current general …

An Assessment Of Image Distortion And Ct Number Accuracy Within A Wide-Bore Ct Extended Field Of View, Bradley Beeksma, D Truant, Lois C. Holloway, Sankar Arumugam

Faculty of Engineering and Information Sciences - Papers: Part A

Although wide bore computed tomography (CT) scanners provide increased space for patients, the scan field of view (sFOV) remains considerably smaller than the bore size. Consequently, patient anatomy which spans beyond the sFOV is truncated and the information is lost. As a solution, some manufacturers provide the capacity to reconstruct CT images from a partial dataset at an extended field of view (eFOV). To assess spatial distortion within this eFOV three phantoms were considered a 30 x 30 x 20 cm3 slab of solid water, the Gammex electron density CT phantom and a female anthropomorphic phantom. For each phantom, …

A Refined General Summation Law For Vu Emission Assessment In Radial Networks, Jayatunga Vitharanage Upuli Priyadarshani Jayatunga, Sarath Perera, Philip Ciufo, Ashish P. Agalgaonkar

Faculty of Engineering and Information Sciences - Papers: Part A

Voltage unbalance (VU) management of power systems requires the development of well researched engineering practices to maintain acceptable VU levels while utilising the total VU absorption capacity of the power system. In this regard, IEC/TR 61000-3-13:2008 prescribes a VU emission allocation methodology based on a stochastic approach which uses a general summation law in order to aggregate numerous sources of unbalance to take into account their random variations. On the other hand, recent deterministic studies on VU emission assessment at the post-connection stage of unbalanced installations present a complex VU factor based approach to determine constituent components of the post-connection …

Interfacial Assessment Of Cao-Al2o3-Sio2-Mgo Slags On Mgal2o4 Spinel, Hamed Abdeyazdan, Neslihan Dogan, M Akbar Rhamdhani, Michael Chapman, Brian J. Monaghan

Brian Monaghan

Steel cleanness is an important and growing research area driven by the demands to produce high quality steel. Lowering the inclusion content in steel is an important criterion for clean steel. It is therefore important to better understand the interaction between inclusions and slag to improve the removability of inclusions from liquid steel. For efficient inclusion removal the inclusions must attach/bond with the slag phase. The strength of the attachment can be characterised by the wettability of the slag on the inclusions. In this study, the dynamic wetting of ladle slags of the CaO-Al2O3-SiO2- MgO system on a solid spinel …

Performance Based Seismic Assessment Of Bridges Designed According To Canadian Highway Bridge Design Code, M Neaz Sheikh, Frederic Legeron Jan 2014

Performance Based Seismic Assessment Of Bridges Designed According To Canadian Highway Bridge Design Code, M Neaz Sheikh, Frederic Legeron

Faculty of Engineering and Information Sciences - Papers: Part A

Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have been specified, there is no explicit requirement in the CHBDC to check the attainment of such performance objectives for the designed bridges. Also, no engineering parameters have been assigned to the specified performance objectives. This paper correlates seismic performance objectives (both qualitative and quantitative) with engineering …
