Vision training: Does the incorporation of jumping on a trampoline increase the effectivity of vergence range building during vectographic training?

The purpose of this study was to examine the effects of vectographic training on vergence ranges and to determine whether incorporation of trampoline jumping would potentiate vergence range building . Thirty-four subjects were randomly divided into three groups. The two experimental groups, one standing the other jumping on a trampoline, received 12 sessions of vectographic training. Phorias and vergence ranges were measured for all three groups, including a control group who received no training, before, after, and three months following the training period. After completing three total hours of training there was no significant difference in the increased ranges between the two experimental groups, or three months later. However, both experimental groups had significantly increased their vergence ranges compared to the control group. In addition we found that training had a greater effect on results at 40cm than at 6m, there was a greater change in the convergence ranges than the divergence ranges, and recoveries for the trampoline group at far increased significantly

Uncertainties in seawater thermometry deriving from intratest and intertest Mg/Ca variability in <em>Globigerinoides ruber</em>

Laser ablation inductively coupled plasma-mass spectrometry microanalysis of fossil and live Globigerinoides ruber from the eastern Indian Ocean reveals large variations of Mg/Ca composition both within and between individual tests from core top or plankton pump samples. Although the extent of intertest and intratest compositional variability exceeds that attributable to calcification temperature, the pooled mean Mg/Ca molar values obtained for core top samples between the equator and &gt;30°S form a strong exponential correlation with mean annual sea surface temperature (Mg/Ca mmol/mol = 0.52 exp0.076SST°C, r2 = 0.99). The intertest Mg/Ca variability within these deep-sea core top samples is a source of significant uncertainty in Mg/Ca seawater temperature estimates and is notable for being site specific. Our results indicate that widely assumed uncertainties in Mg/Ca thermometry may be underestimated. We show that statistical power analysis can be used to evaluate the number of tests needed to achieve a target level of uncertainty on a sample by sample case. A varying bias also arises from the presence and varying mix of two morphotypes (G. ruber ruber and G. ruber pyramidalis), which have different mean Mg/Ca values. Estimated calcification temperature differences between these morphotypes range up to 5°C and are notable for correlating with the seasonal range in seawater temperature at different sites.

Silenced Female Voices: How Institutionalized Avoidance Condones a Culture of Workplace Aggression and Shame in Higher Education

Numerous studies describe the harsh realities of workplace aggression. Many of these studies originated in Scandinavia and Australia, but in recent years research in workplace aggression has increased in the U.S. Researchers attribute workplace aggression to negative emotional, physical, and psychological outcomes. More recently, researchers studied workplace aggression in higher education populations such students, faculty, and administrators, however, research on professional staff is insufficient. In this three-manuscript dissertation study, I explored the lived adverse interpersonal experiences of female professional staff in higher education and discovered how they moved through the experiences. I offer an alternative to the male “normal experience” through a feminist post-intentional phenomenological lens of female professional staffs’ experiences with workplace aggression in higher education. Tentative manifestations, or themes, and discussion provide insight to the female lived experiences of workplace aggression and shame in higher education. I found the participants’ experiences included different types of workplace aggression: incivility, bullying, harassment, and emotional abuse. As a result, female professional staff felt elements of shame such as being trapped, powerless, and isolated. I explored how the participants moved through their experiences utilizing components of shame resilience. The majority of participants’ voices were silenced as they reached out for help. Their institutional representatives avoided reports of bullying and abuse, consequently silencing and shaming their voices. The results of this study contribute to the literature on higher education organizational culture, workplace aggression, feminist phenomenology, and shame resilience theory.doctoral, Ph.D., Leadership and Counseling -- University of Idaho - College of Graduate Studies, 2019-0

Comparison of predicted secondary organic aerosol formation from isoprene to aerosol formation from monoterpene reactions in southeast Texas

In the eastern half of Texas, the atmospheric reactions of hydrocarbons released by vegetation can lead to significant quantities of fine particulate matter. Previous analyses have indicated that the reaction of ozone with monoterpenes (especially α-pinene) is the dominant chemical pathway for the formation of fine particulate matter from biogenic hydrocarbon emissions. These analyses neglected the reactions of isoprene, however, and isoprene represents roughly 80% of the mass of biogenic volatile organic compound (BVOC) emissions in eastern Texas. Conversion of even a small fraction of the isoprene emissions to condensable products could therefore make a significant contribution to biogenic secondary organic aerosol (SOA) formation. This work utilizes two approaches to estimate SOA formation from the atmospheric reactions of isoprene with the hydroxyl radical. One approach involves a simple SOA yield model, which is based on SOA yield data from environmental chamber experiments. The other approach uses molecular reaction mechanisms, based on postulated reaction pathways and estimated rate parameters. The two SOA formation models were incorporated into the photochemical grid model, CAMx 3.10, and used to predict SOA formation from isoprene during the period of August 28 to 31, 2000. Both models predict SOA formation in southeast Texas from the reaction of isoprene with OH to be considerably less than the yield of SOA from the reactions of monoterpenes (α-pinene/O₃, β-pinene/ NO₃ and β-pinene/OH). The daily SOA formation, due to isoprene reactions, estimated using the yield model is about 5% of the yield from the dominant monoterpene reaction pathway - α-pinene/O₃. The SOA formation from isoprene predicted using the molecular mechanism, is about 10% of the isoprene SOA yield model estimatesChemical Engineerin
