Exploring the father-son relationship in college men
On campuses and institutions across the country college men have emerged as a new at-risk group due to concerns of academic, social, emotional, health related, conduct related, and attitudinal natures. This study utilized phenomenological interviewing to explore and better understand the socialization of college men through the father-son relationship. Five undergraduate men at a midsized public university in the Midwest participated in this study. Four major themes and results suggest that fathers are one of the most influential and socially significant figures in the life of men and that college impacted the participants to adopt contemporary views of masculinity and fatherhood

Peer victimization of children with disabilities: examining prevalence and early risk and protective factors among a national of children receiving special education services
Peer victimization is a serious social problem that can negatively affect a child’s psychosocial development and school adjustment, and may have lasting effects for victims. Previous studies on peer victimization have suggested that children with disabilities (CWD) are likely to be more frequent targets of peer victimization. This longitudinal study analyzed three waves of data from the Pre-Elementary Education Longitudinal Study data (N = 1,268). Using the child-by-environment model as a conceptual framework, the study examined the prevalence, nature, and pathways between child characteristics, family factors, school factors at Wave 1, peer-relation difficulties at Wave 2, and peer victimization at Wave 3. To account for the complex sampling used in the dataset, statistical analyses were conducted using Stata 10 and included descriptive analyses, cross-tabulations, Pearson correlations, and a path analysis with AMOS 17.0. The findings showed that one quarter to one third of pre-elementary CWD experienced some form of peer victimization in school. Peer victimization increased over the 3-year study period, and there were also substantial rates of multiple victimization among CWD. The path model showed an acceptable fit to the data. Two pathways explained the influence of risk and protective factors for peer victimization among young CWD. First, children’s environmental factors, such as low family income and spending more time in a special-education classroom setting, were associated with children’s poor social behaviors, which in turn affected peer-relation difficulties, and increased peer victimization. Second, CWD from low-income families and special-education classroom settings were more likely to have poor language development and social skills, which affected children’s peer-relation difficulties and increased peer victimization. These results suggest the need to provide bullying prevention and intervention strategies for CWD, which have been previously neglected in the context of school-based bullying prevention and intervention programs. Practical implications include developing programs tailored for CWD from low-income families and special-education classroom settings, providing mental health services for pre-elementary CWD, linking parents to available school and community resources to improve children’s language and social skills, and promoting polices to enhance social conditions for CWD.Ph.D.Includes bibliographical referencesIncludes vitaby Esther So
Characterization of bacterial processes in the subsurface and the atmosphere:
This dissertation describes research that seeks to expand understanding of bacterially-mediated biotransformation in subsurface groundwater and the atmosphere. In the first study a highly tetrachloroethene (PCE)-enriched culture, RU11/PCE was developed from contaminated aquifer materials. Denaturing gradient gel electrophoresis (DGGE), 16S rRNA clonal library analysis, and direct sequencing of 16S rRNA, sod and gyrB genes revealed a single bacterial species, Dehalococcoides, in the RU11/PCE culture. However, because the 16S rRNA, sod and gyrB genes of the Dehalococcoides spp. are highly conserved, the possibility that more than one strain of Dehalococcoides was present could not be conclusively eliminated. The reductive dehalogenase gene profile of the RU11/PCE culture was different than that of other previously reported Dehalococcoides pure cultures and unlike other chloroethene-respiring Dehalococcoides spp., RU11/PCE grew on PCE, TCE, cis-1,2-DCE or VC.
The second study addressed the hypothesis that the air contains an active microbial ecosystem. Rotating bioaerosol bioreactors were manufactured to keep bacteria suspended in the presence of a volatile substrate while measuring their activity. A qPCR method was developed and used along with an ATP assay, microscopy, and plate counts to enumerate airborne bacteria. Although the gas-phase reactors could retain bacteria and volatile substrates for days, results using live aerosolized Xanthobacter autotrophicus and Bacillus subtilis indicated no growth. In tests with X. autotrophicus, no culturable cells were recovered under any condition. B. subtilis aerosols from dilute substrate yielded higher culturability than aerosols from distilled water with no TSB substrate. Lack of culturability occurred despite presence of airborne bacteria over time, as measured by qPCR and ATP.
Techniques were also developed to characterize microbial communities in atmospheric samples. The bacterial components of a pooled sample of atmospheric water collected in the vicinity of Oklahoma City, OK were analyzed using DGGE and clone library analysis. From DGGE analysis, six out of eight strains detected belong to the phyla of Actinobacteria, Firmicutes, Proteobacteria and Bacteriodetes. In clone library analysis, 12 bacterial strains were identified (from 78 total) with dominant occurrence of the genera, Sphingomonas, Pedobacter, and Curtobacterium spp. The bacterial populations detected from the two methods were composed of strains of diverse origins.Ph.D.Includes bibliographical references (p. 162-179)by Eun Kyeu So
Regulation of phospholipid synthesis in Saccharomyces cerevisiae by mRNA stability
In the yeast Saccharomyces cerevisiae, the most abundant phospholipid phosphatidylcholine is synthesized by the complementary CDP-diacylglycerol and Kennedy pathways. Using a cki1D eki1D mutant defective in choline kinase and ethanolamine kinase, we examined the consequences of a block in the Kennedy pathway on the regulation of phosphatidylcholine synthesis by the CDP-diacylglycerol pathway. The cki1D eki1D mutant exhibited increases in the synthesis of phosphatidylserine, phosphatidylethanolamine and phosphatidylcholine via the CDP-diacylglycerol pathway. The increase in phospholipid synthesis correlated with increased activity levels of the CDP-diacylglycerol pathway enzymes phosphatidylserine synthase, phosphatidylserine decarboxylase, phosphatidylethanolamine methyltransferase, and phospholipid methyltransferase. However, other enzyme activities, including phosphatidylinositol synthase and phosphatidate phosphatase, were not affected in the cki1D eki1D mutant. For phosphatidylserine synthase, the enzyme catalyzing the committed step in the pathway, activity was regulated by increases in the levels of mRNA and protein. Decay analysis of CHO1 mRNA indicated that a dramatic increase in transcript stability was a major component responsible for the elevated level of phosphatidylserine synthase. We examined the decay pathway of CHO1 mRNA by analyzing the rates of transcript degradation in mutants defective in a specific mRNA decay pathway. When compared with the decay (t1/2 = 10-12 min) of the wild type control, the half-life of CHO1 mRNA was increased (t1/2 > 45 min) in the ccr4D, dcp1D, and xrn1D mutants defective in deadenylation, decapping, and 5’-to-3’ exonucleolytic degradation, respectively. The stability of CHO1 mRNA also increased in the ski4-1 mutant defective in the 3’-to-5’ exosome-mediated decay pathway. These results indicated that CHO1 mRNA in S. cerevisiae is degraded through the 5’-to-3’ and 3’-to-5’ decay pathways. We also found that CHO1 mRNA decay was defective in respiratory deficient mutants that were derived from wild type cells and from an eki1 D mutant. The respiratory inhibitor KCN caused a dose dependent increase in CHO1 mRNA stability. This increase in mRNA stability was recapitulated in a cox4D mutant defective in the cytochrome c oxidase enzyme. These results indicated that mitochondrial respiration was required for normal CHO1 mRNA decay.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Hyeon-Son Cho
The Blockchain–Sustainability Nexus: Can This New Technology Enhance Social, Environmental and Economic Sustainability?
With the rise and fall of the prominence of Bitcoin, blockchain technology,
which provides public online ledgers used for the verification and recording of
transactions, has started to become the center of attention for diverse parties in the
global financial system. This chapter explores the nature of blockchain and discusses
how it may contribute to, or obstruct, sustainability. To this end, first, blockchain
technology is introduced. Next, a short discussion on sustainability is presented,
including how it is defined, measured, reported, and understood in theoretical
frameworks. After that, the 2015 United Nations Sustainable Development Goals
are briefly explained. This is followed by a systematic literature review, which
highlights the scarcity of literature linking blockchain to sustainability. Finally, the
author offers her own reflections on the potential of blockchain to revolutionize the
financial services industry and weighs up the pros and cons vis-a-vis sustainable
development.2-s2.0-8514316679
