Flatheaded and Roundheaded Borer Management and Phenology in Nursery Systems
No full textFlatheaded borers (Coleoptera: Buprestidae) and longhorn beetles (Coleoptera: Cerambycidae) are common pests in nursery production systems. The goals of this study were to examine characteristics of a pest buprestid [flatheaded appletree borer, Chrysobothris femorata (Olivier)] and cerambycid [tupelo borer, Aegomorphus morrisi (Uhler)]. The experiments included investigations of phenology, and the development of an artificial diet that would aid in rearing beetles for further studies. Stress factors such as mechanical damage and herbicide-stressed-foliage were evaluated for effects on beetle tree attacks and trap captures. Both beetles were successfully reared from artificial diet from older instars; however, flatheaded borer larvae showed less signs of diet feeding compared to longhorn beetle larvae. In the field, adult flatheaded borers were fully developed at ~746 growing degree days (GDD) (base 10°C [50°F]) based on dissections of trees in spring. Different mechanical stress treatments showed that large red maples with a trunk wedge removed had more attacks than girdled or felled trees. Based on the data, higher attacks may be due to the tree still being partially alive and declining more slowly when attacked versus completely dead. When looking at the attractiveness of herbicide-stressed vegetation, vegetation sprayed throughout the summer months did not affect the number of flatheaded borers caught on traps. This study also evaluated different lures commonly used to attract a variety of longhorned beetles for ability to capture tupelo borer; however, the tupelo borer was not trapped using fuscumol or fuscumol acetate. With this information collected better management strategies and practices to reduce flatheaded borer and longhorn beetle attacks within a nursery system can be evaluated

Feasibility of a Telehealth-Delivered Breathing Intervention for Patients with Idiopathic Pulmonary Fibrosis
No full textIdiopathic pulmonary fibrosis (IPF) is a debilitating chronic lung disease that affects approximately 100,000 individuals in the United States (US), with 30,000 to 40,000 new cases diagnosed each year. Dyspnea is experienced by 90% of patients with IPF and is correlated with reduced quality of life, anxiety, depression, and decreased survival time in this patient population. Breathing management techniques such as pursed lip and diaphragmatic breathing can reduce perceived dyspnea, however this symptom management strategy is not readily taught to patients outside of inpatient hospital settings and pulmonary rehabilitation programs, the latter of which only being accessed by 3% of individuals with chronic lung disease. Telehealth is a cost-effective way to deliver high-quality care to patients and can increase access to healthcare services, such as a symptom management intervention. The purpose of this dissertation study was to measure the feasibility and usability of a telehealth-delivered breathing intervention for patients with IPF, as well as to describe within-group changes in dyspnea, quality of life, anxiety, and depression pre- and post-implementation of a 4-week breathing exercise intervention delivered via telehealth. Among community-dwelling IPF patients, a telehealth-delivered breathing intervention is a feasible and usable option to increase access to this imperative symptom management education. Analysis of pre- and post-intervention data collected on dyspnea, quality of life, anxiety, and depression provides initial evidence that a 4-week intervention may positively influence symptoms experienced by IPF patients

Against the Text: Reimagining Creative Struggle in the Hypostasis of the Archons and William Blake’s The Four Zoas
No full textThe creation stories of Genesis have left something to be desired for many readers, as\ud
seemingly male figures create the world with minimal effort and personal repercussions. The Hypostasis of the Archons and William Blake’s The Four Zoas reimagine the primordial cosmos as involving more complex, prolonged acts of creation which require struggle on the part of the creators. This thesis focuses on female figures as acting independently of male figures,\ud
specifically addressing the role intention plays in creating. Male responses to these female acts of creation vary from adulation to outrage, but often include rape. Yet in both the Hypostasis and the Zoas, the children born of these rapes proffer a brighter future for humanity. In both these\ud
stories, humankind is descended from the female figures, which sets up the human race to\ud
struggle like its primordial predecessors. These texts provide an opportunity for such struggle. One must wrestle with the complex stories and symbols of these texts in order to comprehend what is happening. This proves fruitful though, allowing readers to experience the psychological effects of the text as a primary response, with mimetic understanding becoming a secondary priority. The authors, too, engage in such creative acts, as they engage with previous texts, and as Blake continuously revises his work. There is only so much creative control one can have though when one is mortal, as death will ultimately cause a divide between author and work. As both these material texts have outlived their authors, the texts have fallen into states of disrepair, subject to censorship and loss. This provides the opportunity for further creative acts on the part of readers and scholars, as they fill in gaps and attempt to restore what once was there. In these two texts, the creation story is expanded to include more female figures and is designed to encompass humankind as a whole, allowing these stories to become a part of readers’ personal narratives
Mapping the increasing sophistication of students’ understandings of plate tectonics: A learning progressions approach
No full textPlate tectonics is the organizing paradigm of geosciences, but it is also conceptually complex, and students often struggle with developing a system level understanding of the earth. This article reports on research designed to create a characterization of the different levels of sophistication around plate tectonics in the form of a learning progression for middle grades (grades 6–9). A learning progression is an educational research construct that can guide curriculum, assessment, and instruction by creating a description not just of students’ misunderstandings but of a sequential pattern of increasingly sophisticated and productive student conceptions. This article reports on research findings from a 7-year National Science Foundation-funded project focused on the teaching and learning of earth and space science, which engaged in hundreds of conceptual interviews with students in diverse contexts across the state of Pennsylvania. This article focuses on the implications for higher education faculty in geosciences with regard to the preparation of students, the likely alternative conceptions they may hold, and hence instructional approaches to help their ideas mature toward a normative scientific understanding. © 2019, © 2019 National Association of Geoscience Teachers.National Science FoundationThis material is based upon work supported by the National Science Foundation under Grant No. DUE - 0962792.

Latrine use, boiled water, and bed nets: associations between biomarkers of immune status and public health in a subsistence population
No full textabstract: This study examines associations between clean water, sanitation, mosquito net usage, and immune biomarkers among the Tsimane, a remote subsistence population of forager-horticulturalists with a high pathogen load. Interviews with heads of household (n=710, aged 18-92, median age 40 years) were conducted to ascertain household water sources, ownership and usage of mosquito nets, and latrine use. In this sample, 21% of households used latrines, 20% always boiled their water, and 85% used mosquito nets. Regression models estimate their associations biomarkers of pathogen exposure, including white blood cell count (WBC), hemoglobin (Hb), eosinophils, and sedimentation rate (ESR). Controlling for age, sex, and distance from the closest market town, latrine use (Std. β = -0.11, p= 0.017) and boiling water (Std. β = -0.08, p= 0.059) are associated with lower WBCs. Latrine use is marginally associated with higher hemoglobin (Std. β = 0.09, p= 0.048), but not boiling water (p= 0.447). ESR trends toward lower levels for households that always boil water (Std. β= -0.09, p= 0.131), but is not associated with latrine use (p=0.803). Latrine use was significantly associated with lower eosinophil counts (Std. β= -0.14, p=0.013), but not boiling water (p=0.240). Mosquito nets are not associated with any of these biomarkers. Both boiling water and latrine use are associated with better health outcomes in this sample. These results suggest that scarce public health resources in rural subsistence populations without malarial risk may wish to prioritize boiling water and latrine use to improve health outcomes
Long-duration transit and food and water deprivation alter behavioral activities and aggressive interactions at the feed bunk in beef feedlot steers
No full textThe objective of these experiments was to assess the effects of food and water deprivation and transit duration on the behavior of beef feedlot steers. In Experiment 1, 36 Angus-cross steers (353 ± 10 kg) were stratified to six pens and assigned one of three treatments (n = 12 steers/treatment): control (CON; stayed in home pens with ad libitum access to feed and water), deprived (DEPR; stayed in home pens but deprived of feed and water for 18 h), or transported (TRANS; subjected to 18-h transit event and returned to home pens). In Experiment 2, 60 Angus-cross steers (398 ± 5 kg; 6 steers/pen) were transported either 8 (8H) or 18 (18H) h. Four 8H pens (n = 24 steers) and six 18H pens (n = 36 steers) were used for behavioral analysis. In both experiments, the time to eat, drink, and lay down was recorded for each steer upon return to home pens. Total pen displacements from the feed bunk were also assessed for the two hours following feed access in both experiments. Data were analyzed using Proc Mixed of SAS 9.4, with treatment as a fixed effect. Steer was the experimental unit for behavioral activities, while pen was the experimental unit for bunk displacements. Displacements were analyzed as repeated measures with the repeated variable of time. In Experiment 1, time to eat and drink was similar across treatments (P ≥ 0.17). However, TRANS laid down in 16.5 min while DEPR did not lay down until 70.5 min post-arrival to pen (P < 0.01). Deprived steers had greater bunk displacements in the first 70 min post-feed access than CON or TRANS, though displacements among treatments from 100 to 120 min post-feed access were similar (Treatment × Time: P = 0.02). In Experiment 2, both 8H and 18H steers laid down approximately 25 min post-home pen arrival (P = 0.14). There was no effect of transit duration or duration by time on bunk displacements (P ≥ 0.20), though displacements were greater from 0 to 20 min than from 20 to 30 min post-feed access (Time: P = 0.04). Steers that were deprived of feed and water were highly motivated to access those resources, while transported steers prioritized laying down. Producers should consider these priorities when preparing to receive cattle from a long transit event.This is a pre-copyedited, author-produced version of an article accepted for publication in Journal of Animal Science following peer review.

Skin Carotenoid Levels as a Biomarker of Overall Health
No full textTITLE: Skin carotenoid levels associated with a comprehensive health survey: The USU Wellness Expo AUTHOR(S): Elizabeth King, Linzy Peterson Background: Carotenoids are pigments found in fruits and vegetables that are important bioactive nutrients for humans. Current research suggests lower risk for mortality and chronic diseases with higher dietary intake of fruits and vegetables. Concentration of skin carotenoids is correlated with fruit and vegetable intake in adults. This study looked at the correlation between skin carotenoid levels and overall health status. Purpose: The purpose of this study was to examine the associations between a composite indicator of overall health and levels of skin carotenoids among participants of the USU Wellness Expo. Setting: Utah State University, Winter, 2017 Methods: Adult volunteers (n=167) attending the Expo completed an electronic survey with 50 questions about their overall health. Categories included physical activity, nutrition, general health, safety, social and environmental wellness, emotional awareness, mental wellness, intellectual wellness, occupational wellness, and values, spirituality, and beliefs. Each person had weight and height measured, BMI calculated, and body fat measured using the Omron Bio-Impedance Scale. The BioPhotonic S3 scanner was used to measure skin carotenoid levels for each individual. Pearson correlation examined associations of scanner level and total health score. ANOVA was used to examine associations of quartiles of the total health score, total diet sub-score, and total physical activity sub-score with scanner level. Results: As total health score, diet score, and physical activity score increased, scanner score increased (p≤0.001, p≤0.001, p≤0.003, respectively). Total health score and scanner score had a small but significant correlation (r=0.31, p=0.001). Conclusion: These results suggest that skin carotenoid levels may be a valuable biomarker of total health. Further research is warranted

AND Complete Results - Combined All-Around; Team Results On the difference of competing at a host school and a neutral site: "I think that the Gwinnett Center has put on a tremendous championship thus far. We had experience with that when they put on the SEC championship. The attendance and the support in general-whether it\u27s for one team or another, it doesn\u27t matter-it\u27s just the support and it\u27s the environment and the event itself. We knew coming into the national championship that it was going to be top-notch once again. We would much rather be somewhere where there is a huge support system and a crowd behind anyone and where there is an audience appreciating great gymnastics. " FLORIDA FRESHMAN KYTRA HUNTER On winning the all around as a freshman: "I\u27m really honored to win the all around title. I went in to each event and I just stayed in my bubble and the team\u27s bubble. We had fun. I think we do a lot better when we\u27re loose and not uptight. During the byes, we were dancing around in the locker room. Tomorrow\u27s a new day and I\u27m honored to be in the Super Six with my team." On today\u27s experience and going into tomorrow: "Tomorrow\u27s a new meet. It\u27s a challenge and it\u27s a challenge for each team. Whoever comes out on top is the strongest team that day. I think everyone has a good chance of winning it tomorrow." On starting the night well and setting the bar high for other teams: "We weren\u27t really focused on setting the bar, but we were focused on doing the best that we could for ourselves and our team. I think once you hear the enthusiasm from the fans, it gets every team going, not just one team."
