We Conquer Death
When the golden sun emerges out of the ocean, he casts a shaft of his glorious light across the expanse of the water. The glorious reflection of an unspeakably greater light rests upon the Gospel of St. John: the certainty of our victory over death, the believer\u27s assurance that he has conquered death and possesses eternal life as a present reality. To believe on the Son means to have eternal life
Late Quaternary semiarid eolian system dynamics : distribution, timing, and soil geomorphic controls, Black Mesa, northeastern Arizona, USA
According to the University of New Mexico\u27s Office of Graduate Studies, this dissertation follows a hybrid format; the chapters were written as manuscripts to be submitted to peer-reviewed journals. Chapter 1 was published in the journal Quaternary Research (May, 2011) and chapters 2 and 3 will be submitted to appropriate journals soon after this dissertation is published. Chapter 1 announces new age determinations for previously unstudied topographically-controlled eolian deposits and older ages for sand sheets than were reported by previous investigators. Chapter 2 focuses on the distribution, age, and geomorphic implications of topographically-controlled eolian deposits on Black Mesa. Chapter 3 describes the role of advanced soil profile development on the stability of eolian systems; a factor generally overlooked by researchers interested in quantifying the relative activity of sand dunes. Appendix A contains the results of tests that determine the efficacy of samples used in optically stimulated luminescence dating in all three manuscripts

Prevelence and causes of visual impairment and blindness in older adults in an area of India with a high cataract surgical rate.
BACKGROUND: The cataract surgical rate (CSR) in Gujarat, India is reported to be above 10,000 per million population. This study was conducted to investigate the prevalence and causes of vision impairment/blindness among older adults in a high CSR area. METHODS: Geographically defined cluster sampling was used in randomly selecting persons >or= 50 years of age in Navsari district. Subjects in 35 study clusters were enumerated and invited for measurement of presenting and best-corrected visual acuity and an ocular examination. The principal cause was identified for eyes with presenting visual acuity < 20/32. RESULTS: A total of 5158 eligible persons were enumerated and 4738 (91.9%) examined. Prevalence of presenting visual impairment < 20/63 to 20/200 in the better eye was 29.3% (95% confidence interval [CI]: 27.5-31.2) and 13.5% (95% CI: 12.0-14.9) with best correction. The prevalence of presenting bilateral blindness (< 20/200) was 6.9% (95% CI: 5.7-8.1), and 3.1% (95% CI: 2.5-3.7) with best correction. Presenting and best-corrected blindness were both associated with older age and illiteracy; gender and rural/urban residence were not significant. Cataract in one or both eyes was the main cause of bilateral blindness (82.6%), followed by retinal disorders (8.9%). Cataract (50.3%) and refractive error (35.4%) were the main causes in eyes with vision acuity < 20/63 to 20/200, and refractive error (86.6%) in eyes with acuity < 20/32 to 20/63. CONCLUSIONS: Visual impairment and blindness is a significant problem among the elderly in Gujarat. Despite a reportedly high CSR, cataract remains the predominant cause of blindness
The Biology of Climate Change: The effects of changing climate on migrating and over-wintering species at a high-elevation field station
Students engage with long-term environmental and phenology data sets (spanning over 40 years) collected at the Rocky Mountain Biological Laboratory, a high-elevation field station in Colorado, to explore the effects of climate change on the phenology of migrating and hibernating species. After becoming familiar with the geographic context, people involved with the data collection, and organisms studied through background readings and videos, students explore the raw data set in Excel or using an interactive data visualization tool. In small groups, students reproduce figures and regressions from Inouye et al. (2000) based on those data, then expand their analyses with data collected during the subsequent decade. By comparing analyses that encompass different time spans, students evaluate the original interpretations from Inouye et al. (2000), explain possible discrepancies, and generate predictions for future patterns. Finally, students build upon their initial analyses by developing and testing hypotheses about patterns found in other organisms in the data set, and combine these to discuss the ecological consequences of shifting plant and animal phenology in group presentations
