The Reliability Of Indirect Assessments Of Standing Forward Head Posture In Asymptomatic Adults, Bailey Strand

Theses and Dissertations

Background: Measurement reliability has important decision-making implications for physical therapists and researchers when assessing individuals. Given that physical therapists often visually assess forward head posture (FHP) to guide treatment, the aims of this study were to quantify: (a) the reliability of indirect (visual) assessments of standing FHP in asymptomatic adults, and (b) the magnitude of the biological (postural) and technical errors involved.

Methods: A reliability analysis of two indirect assessments (visual assessments of real and 3D body scanned people) of FHP was undertaken. The sample comprised 10 physical therapists and 50 asymptomatic participants. Participants were scanned using the Vitus Smart …

Personal Universes: A Solution To The Multi-Agent Value Alignment Problem, Roman V. Yampolskiy

Faculty and Staff Scholarship

AI Safety researchers attempting to align values of highly capable intelligent systems with those of humanity face a number of challenges including personal value extraction, multi-agent value merger and finally in-silico encoding. State-of-the-art research in value alignment shows difficulties in every stage in this process, but merger of incompatible preferences is a particularly difficult challenge to overcome. In this paper we assume that the value extraction problem will be solved and propose a possible way to implement an AI solution which optimally aligns with individual preferences of each user. We conclude by analyzing benefits and limitations of the proposed approach.

A Seat At The Table: Information Literacy Assessment And Professional Legitimacy, Amber Willenborg, Robert Detmering, Samantha Mcclellan

Faculty and Staff Scholarship

This qualitative study explores academic librarians’ perceptions of and experiences with information literacy assessment, focusing primarily on issues of professional identity, agency, and power. Findings from in-depth interviews reveal that instruction librarians view teaching as integral to their professional identity and use assessment to legitimize that identity, both personally and at the institutional level. While this suggests that assessment has the potential to elevate the status of librarians on campus, the interviews also highlight ongoing professional and organizational tensions that hinder assessment efforts and inhibit librarian agency. The authors recommend more transparent communication, among other strategies, to address these challenges.

Emergence Of Addictive Behaviors In Reinforcement Learning Agents, Vahid Behzadan, Roman Yampolskiy, Arslan Munir

Faculty and Staff Scholarship

This paper presents a novel approach to the technical analysis of wireheading in intelligent agents. Inspired by the natural analogues of wireheading and their prevalent manifestations, we propose the modeling of such phenomenon in Reinforcement Learning (RL) agents as psychological disorders. In a preliminary step towards evaluating this proposal, we study the feasibility and dynamics of emergent addictive policies in Q-learning agents in the tractable environment of the game of Snake. We consider a slightly modified version of this game, in which the environment provides a “drug” seed alongside the original “healthy” seed for the consumption of the snake. We …

Worldview Conflict In Daily Life, Mark J. Brandt, Jarret T. Crawford, Daryl R. Vantongeren

Faculty Publications

Building on laboratory- and survey-based research probing the psychology of ideology and the experience of worldview conflict, we examined the association between worldview conflict and emotional reactions, psychological well-being, humanity esteem, and political ideology in everyday life using experience sampling. In three combined samples (total N = 328), experiencing disagreement compared to agreement was associated with experiencing more other-condemning emotions, less well-being, and less humanity esteem. There were no clear associations between experiencing disagreement and experiencing self-conscious emotions, positive emotions, and mental stress. None of the relationships were moderated by political ideology. These results both replicate and challenge findings from …

Project Access: High School Student Learning Of Academic Vocabulary In The Rio Grande Valley, Angela M. Chapman

Teaching and Learning Faculty Publications

Academic language can be a major obstacle to students’ learning in science and math. For English Language Learners this challenge can be even greater. One reason this challenge prevails is the persistent deficit perspective toward students whose native language is Spanish. One way to address this issue is to leverage students’ knowledge of Spanish and personal culture to develop a deeper understanding of academic vocabulary in high school math and science courses. Project ACCESS (Acquisition of Curricular Content for Exceptional Success in STEM) seeks to challenge the assumptions and biases toward students in the Rio Grande Valley (RGV) who have …

Teacher Candidate Immersion Into Bilingual/ Dual Language Classrooms In Largest Urban District In Texas, Bobbette M. Morgan, Criselda Garcia, John Jauregui

Teaching and Learning Faculty Publications

Prevailing teacher education reform initiatives call for preservice preparation to be "clinically rich" shifting the primary locus, and therefore location, of learning from within university walls to schools (National Council for Accreditation of Teacher Education, 2010; New York State Department of Education, 2011; U. S. Department of Education, 2009, 2011). In an effort of the largest school district in Texas to recruit our bilingual preservice teachers and for us to expose our students from the Rio Grande Valley to a highly populated urban setting, our students are invited to spend one week with host families and shadow an experienced teacher …

A Transfer Matrix Model Of The Iec 60318-4 Ear Simulator: Application To The Simulation Of Earplug Insertion Loss, Yu Luan, Franck Sgard, Simon Benacchio, Hugues Nélisse, Olivier Doutres

Études primaires

The IEC 60318-4 ear simulator is used to measure the insertion loss (IL) of earplugs in the ear canal of an acoustical test fixture (ATF) and is designed to represent an average acoustic impedance (in a reference plane) of the human ear. The ear simulator is usually modeled using a lumped parameter model (LPM) which has frequency limitations and inadequately accounts for the thermo-viscous effects in the simulator. The simulator numerical models that can better deal with the thermo-viscous phenomena often lack essential geometric details. Most related studies also suffer from the lack of experimental validation of the models. Therefore, …

Maintaining Lumbar Spine Stability: A Study Of The Specific And Combined Effects Of Abdominal Activation And Lumbosacral Orthosis On Lumbar Intrinsic Stiffness, Christian Larivière, Jean-Alexandre Boucher, Hakim Mecheri, Daniel Ludvig

Études primaires

Abstract

Background:

Two potential interventions for enhancing lumbar stability are to actively increase abdominal muscle activity, either through the abdominal drawing-in maneuver (ADIM) or bracing, and passively increase lumbar stiffness using a lumbosacral orthosis (LSO).

Objective:

To compare the increase in lumbar stiffness after 2 active interventions (ADIM versus bracing) and 1 passive intervention (LSO), and to evaluate the combined effect of active (abdominal bracing) and passive interventions.

Methods:

In this experimental and comparative study, lumbar stiffness, a surrogate measure of lumbar stability, was estimated in 25 healthy individuals during 7 trunk perturbation conditions: (1) control, (2) ADIM, (3) bracing …

Procedure To Measure The Penetration Of One Mechanical Filter For Nanoparticles: Validation By Comparison, Pooya Abdolghader, Clothilde Brochot, Fariborz Haghighat, Ali Bahloul

Études primaires

Nanoparticles (NPs) are particles of less than or equal to 100 nm in diameter. Due to their size, they have a significant effect on health and safety of people. Capture of these NPs in general ventilation systems by filters remains one of the most widely used means of protection due to its relative simplicity of implementation and its effectiveness for capturing various size of particles. In North America, filters used in general ventilation systems are tested by the ANSI/ASHRAE Standard 52.2 and are graded according to their efficiency, which is a function of particle diameter. However, the current standard limits …

Revisiting The Effect Of Manipulating Lumbar Stability With Load Magnitudes And Positions: The Effect Of Sex On Trunk Muscle Activation, Christian Larivière, Ali Shahvarpour, Christina Gravel, Myriam Gauvin, Anne-Marie Jean, Ariane Viau, Hakim Mecheri

Études primaires

Background

Lumbar spine stability is regularly studied by positioning different loads at different heights and distance and measuring trunk muscle activation changes. Some of these studies have reported sex differences, but this needs to be revisited while controlling for confounding factors.

Method

20 males and 20 females sustained three static standing postures, with various loads (0, 5 and 10% of body weight), to evaluate the effect of height and distance. Activation of 12 trunk muscles was recorded with surface electromyography (EMG).

Results

Females activated their external obliques a little more than males, with increases ranging between 1.5 and 2.3% of …

The Immediacy Of Genome Editing And Mitochondrial Replacement, Raymond C. O'Brien

Scholarly Articles

After human DNA was first defined in 1953, the parallel science of assisted reproductive technology achieved a successful human birth through in vitro fertilization in 1978. Science then went on to facilitate gestational surrogacy, banking human reproductive materials, such as embryos, and greater opportunities for couples and individuals to become parents. Fertility clinics were established throughout the world to help persons and couples achieve parenthood, contributing to a steady increase in babies born through assisted reproductive means. Gradually, both federal and state laws in the United States were enacted to collect data from the fertility clinics, mandate insurance coverage of …

Creative Lesson Planning With College And Career Readiness Standards: Thoughts From The Curriculum Library, Margaret Robillard

Journal of Excellence in College Teaching and Learning

Preservice teachers carefully craft lesson plans to meet the academic needs of elementary through high school students in their fieldwork. They rely in part on finding high quality texts and trade books that relate to College and Career Readiness Standards (CCR). While college curriculum libraries are excellent sources for materials, their organization often is not aligned with national curriculum academic standards. Preservice teachers therefore sometimes struggle to find appropriate analog resources to create lesson plans that integrate disciplinary literacy. This research utilizes CCR standards, survey data from stakeholders, and library organizational research literature to create a categorization system based on …

Reflections On Changing Pedagogy Of Augmentative And Alternative Communication, Kelly Kleinhans, Lauren E. Bland, Richard Dressler

Journal of Excellence in College Teaching and Learning

Augmentative and alternate communication (AAC) is a service delivery area in the field of speech-language pathology. Individuals with significant and complex communication impairments benefit when a speech-language pathologist develops a communication system that either replaces or augments traditional speech. AAC includes the use of assistive technology designed to represent language and produce voice output. The profession's credentialing body, the American Speech-Language Hearing Association, requires university training programs to document student's knowledge and skills in AAC for working with clients across the lifespan. The authors reflect on how pedagogy associated with AAC has been transformed over time by external influences like …

Unity As The Primary Principle In A New Approach To Professional Development: Aligning Programming Through Milestone Events To Create Faculty Learning, Russell Carpenter, Charlie Sweet, Hal Blythe, Carolyn Grace

Journal of Excellence in College Teaching and Learning

Authors offer a model for unifying professional development of faculty through aligning programming based on core-learning threads. This approach allows participants to embed new knowledge into a “larger context,” which Brown, Roediger, and McDaniel (2014) argued “helps learning” (p. 6). Our Center for Teaching and Learning (CTL) unifies all events—Teaching & Learning Innovation (TLI) series sessions, Professional Learning Communities (PLCs), and faculty institutes—around these core-learning threads. This unified programming is supported by online experiences offered within the Developing Excellence in Eastern’s Professors (DEEP) system (Carpenter, 2017). Through this approach, authors use milestone events as opportunities to reinforce core-learning threads and …

Use Of Magnetic Resonance Image Registration To Estimate Displacement In The Human Earcanal Due To The Insertion Of In-Ear Devices, Simon Benacchio, Olivier Doutres, Arthur Varoquaux, Éric Wagnac, Arnaud Le Troter, Virginie Callot, Franck Sgard

Études primaires

In-ear devices are used in a wide range of applications for which the device's usability and/or efficiency is strongly related to comfort aspects that are influenced by the mechanical interaction between the device and the walls of the earcanal. Although the displacement of the earcanal walls due to the insertion of the device is an important characteristic of this interaction, existing studies on this subject are very limited. This paper proposes a method to estimate this displacement in vivo using a registration technique on magnetic resonance images. The amplitude, the location and the direction of the earcanal wall displacement are …

Rethinking Information Literacy Assessment: Relevance, Reliability, And Validity Of Constructs And Measures, Melissa Clark

Librarian and Staff Publications

Information literacy assessment has traditionally approached student learning as the acquisition of declarative knowledge, which can be measured with easily-graded true/false and multiple-choice questions. Although such measures may prove highly reliable in test-retest situations, they are not valid measures of knowledge or learning, because they fail to test procedural and conditional knowledge, both of which are essential for students to reach the higher levels of Bloom’s taxonomy. This omission can partially explain the disconnect between scores on tests of information literacy and students’ continued poor performance on research assignments. Furthermore, information literacy assessment has failed to address the social and …
