Does modality make a difference? A comparative study of mobile augmented reality for education and training

Includes bibliographical references.2022 Fall.As augmented reality (AR) technologies progress they have begun to impact the field of education and training. Many prior studies have explored the potential benefits and challenges to integrating emerging technologies into educational practices. Both internal and external factors may impact the overall adoption of the technology, however there are key benefits identified for the schema building process, which is important for knowledge acquisition. This study aims to elaborate and expand upon prior studies to explore the question does mobile augmented reality provide for stronger knowledge retention compared to other training and education modalities? To address this question this study takes a comparative experimental approach by exposing participants to one of three training modalities (AR, paper manual, or online video) and evaluating their knowledge retention and other educational outcomes

Deterministic coupling of a single nitrogen vacancy center to a photonic crystal cavity

We describe and experimentally demonstrate a technique for deterministic coupling between a photonic crystal (PC) nanocavity and single emitters. The technique is based on in-situ scanning of a PC cavity over a sample and allows the positioning of the cavity over a desired emitter with nanoscale resolution. The power of the technique, which we term a Scanning Cavity Microscope (SCM), is demonstrated by coupling the PC nanocavity to a single nitrogen vacancy (NV) center in diamond, an emitter system that provides optically accessible electron and nuclear spin qubits

Dopamine Agonists and Pathologic Behaviors

The dopamine agonists ropinirole and pramipexole exhibit highly specific affinity for the cerebral dopamine D3 receptor. Use of these medications in Parkinson's disease has been complicated by the emergence of pathologic behavioral patterns such as hypersexuality, pathologic gambling, excessive hobbying, and other circumscribed obsessive-compulsive disorders of impulse control in people having no history of such disorders. These behavioral changes typically remit following discontinuation of the medication, further demonstrating a causal relationship. Expression of the D3 receptor is particularly rich within the limbic system, where it plays an important role in modulating the physiologic and emotional experience of novelty, reward, and risk assessment. Converging neuroanatomical, physiological, and behavioral science data suggest the high D3 affinity of these medications as the basis for these behavioral changes. These observations suggest the D3 receptor as a therapeutic target for obsessive-compulsive disorder and substance abuse, and improved understanding of D3 receptor function may aid drug design of future atypical antipsychotics

A Distribution of Large Particles in the Coma of Comet 103P/Hartley 2

The coma of comet 103P/Hartley 2 has a significant population of large particles observed as point sources in images taken by the Deep Impact spacecraft. We measure their spatial and flux distributions, and attempt to constrain their composition. The flux distribution of these particles implies a very steep size distribution with power-law slopes ranging from -6.6 to -4.7. The radii of the particles extend up to 20 cm, and perhaps up to 2 m, but their exact sizes depend on their unknown light scattering properties. We consider two cases: bright icy material, and dark dusty material. The icy case better describes the particles if water sublimation from the particles causes a significant rocket force, which we propose as the best method to account for the observed spatial distribution. Solar radiation is a plausible alternative, but only if the particles are very low density aggregates. If we treat the particles as mini-nuclei, we estimate they account for <16-80% of the comet's total water production rate (within 20.6 km). Dark dusty particles, however, are not favored based on mass arguments. The water production rate from bright icy particles is constrained with an upper limit of 0.1 to 0.5% of the total water production rate of the comet. If indeed icy with a high albedo, these particles do not appear to account for the comet's large water production rate. production rate.

Burt Lake Watershed planning project: biological management plan

LimnologyThe Burt Lake Preservation Association wants a management plan to control some of the biological aspects in the Burt Lake watershed. Specifically, the BLPA would like a sustainable sturgeon population, a healthy crayfish population, less invasive plant species, and to understand the signficance of algae growing in Burt Lake. The research team conducted an assessment from June 2016 to August 2016. The assessment encompased a habitat survey for Lake Sturgeon, setting crayfish traps, a plant survey focused on invasive species, and the identification of algae in visible masses. From the assessment it was concluded that the Sturgeon River is the most likely to provide suitable spawing habitat to benefit a sustainable sturgeon pouplation. There is a helathy population of crayfish in Burt Lake, even though the invasive rusty crayfish is present. Curly-leaf pondweed and Eurasian watermilfoil were the only two invasive aquatic plant species found. None of the algae that were identified are invasive or occurring in damaging quantities. Part of the managment plant invluded a list of potential management solutions in order to bring Burt Lake up to the standards of the BLPA.https://deepblue.lib.umich.edu/bitstream/2027.42/134684/4/Kelley_LaPlante_Lyons_Barget_Bilich_DesJardins_Nee_Nguyen_2016.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/134684/5/Burt Lake Management Plan_2016.pdfDescription of Kelley_LaPlante_Lyons_Barget_Bilich_DesJardins_Nee_Nguyen_2016.pdf : SUPERSEDE

Assessment of Early Intervention Services to Better Child Outcomes among Part C Infants and Toddlers

Background: Early intervention services have been shown to improve child outcomes. Rapid proliferation of neural connections and circuits contribute to the rapid growth of the brain in the first three years of life. These neural circuits which create the foundation for learning are most flexible in this period and become increasingly more difficult to change thereafter. The purpose of this study is to examine the relationship between early enrollment in Georgia’s Part C birth to three early intervention program and improved child outcome ratings upon exiting the program at 3 years of age. The study used 2013 & 2014 Annual Performance Report (APR) data. Methods: This study included 6,309 participants who enrolled and received services in the Part C, Babies Can’t Wait (BCW) program. A Pearson’s correlation analysis was used to assess if there was an association between age at enrollment and improved child outcome score. One-way analysis of variance (ANOVA) was used to test the variances within the age groups for equality. Bonferroni post hoc test was used to compare the mean child outcome score across the enrollment age groups. Results: A statistically significant inverse correlation was found between enrollment age and improved child outcome score at 3 years of age. One-way ANOVA showed that the variances within the enrollment age groups were equal while the mean child outcome scores were not. Bonferroni post hoc test revealed that the mean child outcome score in the enrollment age group 0 to ≤ 6 months was significantly higher than the other age groups. Conclusions: Significantly better child outcomes were associated with enrollment in early intervention services before 6 months of age

Health and Housing in an Aging Population: Identifying Risk Factors of Seniors Living Independently

Background: Aging is associated with numerous risk factors for declining physical and mental health. As a result, many elder individuals are forced to relocate to nursing homes, assisted living centers or just closer to adequate medical facilities. Studies have shown: • Relocation of elders is associated with depression, anxiety, memory loss, and decreased social adjustment and life satisfaction • Persistently lonely people exhibit a 2-fold greater risk for developing Alzheimer’s disease (AD) than those who are not chronically lonely • Increased social interaction improves cognitive function in individuals with AD By helping seniors to age in place, many of the deleterious risks of relocation, such as social isolation, depression, and cognitive decline could be avoided. In addition to relocation, other risk factors that affect cognition have been identified: • Physical activity is associated with higher cognitive functioning in elders • Polypharmacy is a risk factor for impaired cognition Thus, simple modifications that allow seniors to age in place may reduce morbidity and enhance quality of life. Cathedral Square Corporation (CSC) is a non-profit organization whose mission is to develop, manage, and own housing that provides community services to promote the health and well-being of elders, low income persons, and persons with disabilities. Students from the University of Vermont College of Medicine (UVM) partnered with CSC in a project to promote aging in place via evaluation of seniors’ current needs and the development of a service model to meet these needs at home.https://scholarworks.uvm.edu/comphp_gallery/1010/thumbnail.jp

Bilingual problem-solving training for caregivers of adults with dementia: A randomized, factorial-design protocol for the CaDeS trial

Objective: Caregivers of individuals with Alzheimer\u27s disease and related dementias (ADRD) often experience debilitating caregiver burden and emotional distress. To address these negative emotional consequences of caregiving, we will test and refine a strategy training intervention - Problem-Solving Training (PST) - that promotes self-efficacy and reduces caregiver burden and depressive symptoms. Previous research supports efficacy of PST; however, we do not know exactly how many PST sessions are needed or if post-training boosters are required to maintain PST benefits. Additionally, we translated and culturally-adapted PST into Descubriendo Soluciones Juntos (DSJ), our novel intervention for Spanish-speaking caregivers. Method: In this 2 × 2 factorial design randomized controlled trial, we will test remotely-delivered PST/DSJ sessions for both English- and Spanish-speaking caregivers of persons with ADRD to determine the optimal number of PST/DSJ sessions and ongoing booster sessions needed to best help caregivers navigate their current and future needs. Aims: 1) Compare the efficacy of three vs. six PST/DSJ sessions each with and without booster sessions for decreasing caregiver burden and depression and enhancing caregiver problem-solving; 2) Identify key factors associated with efficacy of PST/DSJ, including age, gender, primary language, relationship to care recipient, and uptake of the PST/DSJ strategy. Results: These results will establish guidelines needed for an evidence-based, culturally-adapted, and implementable problem-solving intervention to reduce caregiver stress and burden and improve caregiver health and well-being. Conclusion: This work promotes inclusion of diverse and underserved populations and advances therapeutic behavioral interventions that improve the lives of caregivers of individuals with chronic conditions

Performance of the NINDS-CSN 5-Minute Protocol in a National Population-Based Sample

Background In 2006, the National Institute of Neurological Disorders and Stroke-Canadian Stroke Network (NINDS-CSN) Vascular Cognitive Impairment Harmonization Standards recommended a 5-Minute Protocol as a brief screening instrument for vascular cognitive impairment (VCI). We report demographically adjusted norms for the 5-Minute Protocol and its relation to other measures of cognitive function and cerebrovascular risk factors. Methods Cross-sectional analysis of 7,199 stroke-free adults in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study on the NINDS-CSN 5-Minute Protocol score. Results Total scores on the 5-Minute Protocol were inversely correlated with age and positively correlated with years of education, and performance on the Six-Item Screener, Word List Learning, and Animal Fluency (all p-values<0.001). Higher cerebrovascular risk on the Framingham Stroke Risk Profile (FSRP) was associated with lower total 5-Minute Protocol scores (p<0.001). The 5-Minute Protocol also differentiated between participants with and without confirmed stroke and with and without stroke symptom histories (p<0.001). Conclusions The NINDS-CSN 5-Minute Protocol is a brief, easily administered screening measure that is sensitive to cerebrovascular risk and offers a valid method of screening for cognitive impairment in populations at risk for VCI
