Qualitative Mapping For Understanding The Collective Judgment Building Process : A Study Of The Federal Open Market Committee, Hyunjung Kim
Qualitative Mapping For Understanding The Collective Judgment Building Process : A Study Of The Federal Open Market Committee, Hyunjung Kim
Legacy Theses & Dissertations (2009 - 2024)
This study develops a mapping method for studying a collective judgment building process in a decision-making group. Environmental uncertainties and a lack of information require a decision maker to make judgments about various issues relevant to the decision task. In a group setting, the members together weave their structural model of the system with available information to build a collective judgment for the decision task.
The Effects Of Organizational Culture And Climate On Employee's Turnover In Public Child Welfare Agencies, Miseung Shim
The Effects Of Organizational Culture And Climate On Employee's Turnover In Public Child Welfare Agencies, Miseung Shim
Legacy Theses & Dissertations (2009 - 2024)
Background & Purpose: Employee's turnover in child welfare agencies negatively influences remaining employees, clients, and organization itself as well as losing skilled or trained employees. For example, employee's high turnover tends to be cyclical, in that high turnover gives additional workload burden to remaining employees and causes lack of continuity of services for vulnerable children and families. Moreover, child welfare agencies have to bear financial costs, including hiring and training. Although current literature increasingly emphasizes the importance of organizational factors in employee's turnover issues, more empirical research is needed to be conducted to understand organizational effects on employee's turnover. This …
Modeling Peer Influence And Peer Selection As Processes, Bob Edward Vasquez
Modeling Peer Influence And Peer Selection As Processes, Bob Edward Vasquez
Legacy Theses & Dissertations (2009 - 2024)
Behavioral scientists are aware of the strong and persistent correlation between peer and individual behavior. Evidence suggests selection and socialization effects explain the correlation, but the processes, or the details of the ways in which these effects operate in an empirical model, remain relatively unexamined.

Simultaneously, policy implementation responsibilities devolved to states.
Cavity Ring-Down Spectroscopic Study Of Gas-Phase Photolysis Of Unsaturated Dicarbonyls And Aromatic Aldehydes, And Surface Photolysis Of Acetaldehyde, Bin Xiang
Legacy Theses & Dissertations (2009 - 2024)
Photochemical smog is a phenomenon associated with pollution in urban atmospheres arising from the photochemical oxidation of volatile organic compounds (VOCs) in the presence of nitrogen oxides. The oxidation process can lead to ozone and secondary air pollutants including particle formation which reduce visibility. The term "photochemical smog" is used to describe this pollutant mixture. The further degradation of secondary air pollutants could also have an impact on the atmospheric oxidation capacity. However, the atmospheric degradation mechanisms of the secondary pollutants are still not fully understood. In this dissertation, cavity ring-down spectroscopy combined with laser photolysis and Fourier transform infrared …
The Representation Of Multiple Translations In Bilingual Memory : An Examination Of Lexical Organization For Concrete, Abstract, And Emotion Words In Spanish-English Bilinguals, Dana M. Basnight-Brown
The Representation Of Multiple Translations In Bilingual Memory : An Examination Of Lexical Organization For Concrete, Abstract, And Emotion Words In Spanish-English Bilinguals, Dana M. Basnight-Brown
Legacy Theses & Dissertations (2009 - 2024)
Tokowicz and Kroll (2007) originally reported that the number of translations a word has across languages influences the speed with which bilinguals translate concrete and abstract words from one language to another. The current work examines how the number of translations that characterize a word influences bilingual lexical organization and the processing of concrete, abstract and emotional stimuli. Experiment 1 examined whether the number-of-translations effect reported previously could be obtained in a different task (i.e., lexical decision task) using the same materials presented by Tokowicz and Kroll. Decision latencies revealed no significant differences between concrete and abstract words, which suggested …

Legacy Theses & Dissertations (2009 - 2024)
Perfluorochemicals (PFCs) have been used as surfactants and surface protectors in a large number of consumer products. PFCs have been reported to elicit adverse health effects in laboratory animals and humans, and have been detected in foodstuffs and in human bodies. In this dissertation, analytical methods were developed for the determination of trace levels of PFCs in human blood, dried blood spot, breast milk, saliva, and urine. An assessment of human exposure to PFCs was performed by analyzing human specimens collected from the United States and several Asian countries. Blood, breast milk, and dried blood spots were found to be …
Progress Towards Critical Dimension Low Vacuum Scanning Electron Microscopy, Vasiliki Tileli
Progress Towards Critical Dimension Low Vacuum Scanning Electron Microscopy, Vasiliki Tileli
Legacy Theses & Dissertations (2009 - 2024)
Low vacuum scanning electron microscopy (LVSEM) is proposed and evaluated for next generation Critical Dimension (CD) metrology. Its ability to control charging artifacts and hydrocarbon contamination in order to obtain high signal-to-noise ratio, high resolution image data from insulating materials make the technology an excellent match for the increased use of high-k dielectrics and shrinking feature size in the semiconductor industry. The presence of a gas in the LVSEM chamber means that the probe characteristics and secondary electron amplification, detection, and signal-to-noise ratio differ significantly from conventional high vacuum tools. In order for low vacuum CD approaches to be viable, …

Raman Spectroscopy Of Body Fluids : A Nondestructive Identification Technique For Forensic Applications, Kelly Virkler
Raman Spectroscopy Of Body Fluids : A Nondestructive Identification Technique For Forensic Applications, Kelly Virkler
Legacy Theses & Dissertations (2009 - 2024)
The analysis of body fluid evidence during forensic investigations is a complicated process, yet it is a critical step in determining the key facts of a crime. There is no doubt that DNA analysis is an extremely useful tool that can identify a suspect or victim, but crime scene investigators must first locate and identify potential body fluid stains that can be collected for DNA analysis. Current screening tests are destructive to the sample and can give false positive results, so a nondestructive technique such as Raman spectroscopy, that can possibly confirm the presence of a particular fluid, could lend …
The Effects, Brain Targets, And Mechanisms Of Estradiol For Affective Behavior, Alicia Ann Walf
The Effects, Brain Targets, And Mechanisms Of Estradiol For Affective Behavior, Alicia Ann Walf
Legacy Theses & Dissertations (2009 - 2024)
Although estradiol (E2) has numerous effects in the central nervous system, this review will focus on addressing the effects of E2 on behaviors related to mood in women and animal models and include recent findings from our laboratory related to this topic. E2's anti-anxiety and anti-depressant-like effects may depend upon many factors (e.g. age, reproductive history/status, time in E2 deficient state before initiation of E2 therapy, regimen and dosing of E2, neuropsychiatric/stress history). First, evidence of how factors may alter responses to E2 in people and in animal models will be discussed. Second, interactions of E2 with the hypothalamic-pituitary-adrenal axis/stress …
Genetic And Non-Genetic Factors That Cause Inter-Individual Variations In Cyp2a13 Gene Expression, Hong Wu
Genetic And Non-Genetic Factors That Cause Inter-Individual Variations In Cyp2a13 Gene Expression, Hong Wu
Legacy Theses & Dissertations (2009 - 2024)
The overall goal of this dissertation is to investigate the mechanisms underlying the large interindividual variations in susceptibility to lung carcinogenesis. We focused on CYP2A13, a respiratory tract-specifically expressed enzyme, which is the most efficient P450 towards bioactivation of a tobacco-related carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). The expression level of CYP2A13 varies substantially among human lung samples. Our central hypothesis is that CYP2A13 expression level is affected by both genetic regulators and non-genetic factors. The specific aims are 1) to identify the mechanisms underlying the decreased allelic expression of a CYP2A13 allele (7520C>G); 2) to identify frequent single-nucleotide polymorphisms (SNPs), associated …
A Multidimensional Analysis Of The Relationship Between Leader-Member Exchange And Organizational Citizenship Behavior With An Alternative Measure Of Leader-Member Exchange, Yann-Jang Wu
Legacy Theses & Dissertations (2009 - 2024)
Leader-Member Exchange (LMX) theory proposed that a leader will develop a unique exchange pattern with each subordinate (Liden, Wayne, & Stilwell, 1993). Empirically, LMX has shown significant associations with many work outcomes (Gerstner & Day, 1997). One of these valued outcomes is organizational citizenship behavior (OCB), which is defined as action enacted beyond one's assigned duties on the job (Farh, Podsakoff, & Organ, 1990). Positive correlations between LMX and OCB have been demonstrated in previous research (Podsakoff, MacKenzie, Paine, & Bachrach, 2000). Both LMX and OCB were proposed to comprise several sub-factors; nevertheless, correlations between LMX and OCB have always …

The subjects for this study included 4977 of the 4998 students that graduated from a selective institution from 1992 through 1996. Results …
Role Of Cyp2a5 In Drug Metabolism, Chemical Toxicity, And Maintenance Of Steroid Hormone Homeostasis : Insights From Studies On A Novel Cyp2a5-Null Mouse Model, Xin Zhou
Legacy Theses & Dissertations (2009 - 2024)
The central hypothesis is that CYP2A5 plays an important role in the metabolism of xenobiotic substrates, and in the toxicity induced by over-exposure to drugs, as well as in the metabolism of endogenous compounds and regulation of steroid hormone homeostasis. The specific aims are: 1) to generate and characterize a Cyp2a5-null mouse; 2) to determine the role of CYP2A5 in the systemic clearance of nicotine and cotinine; and 3) to explore the mechanisms underlying the resistance of the lateral nasal gland (LNG) of male Cyp2g1-null/Cyp2a5-low mouse and Cyp2a5-null mouse to acetaminophen (AP) toxicity.

Impulsivity, Offending, And The Neighborhood : Investigating The Person-Context Nexus, Gregory M. Zimmerman
Impulsivity, Offending, And The Neighborhood : Investigating The Person-Context Nexus, Gregory M. Zimmerman
Legacy Theses & Dissertations (2009 - 2024)
A key assumption of the traditional trait-based approach to the study of crime is that personality traits cause people to act similarly across a wide array of contexts. This approach has been challenged for its failure to acknowledge differences in the social environments to which individuals are exposed. Similarly, community-level explanations of crime have been criticized for failing to acknowledge that there are important individual differences between criminals and non-criminals. Ultimately, a full understanding of crime requires the consideration of both individual and environmental differences, perhaps most importantly because they may interact to produce offending behavior. In particular, the influence …
Molecular Evolution Of Genes Underlying Phenotypic Differences Between Humans And Chimpanzees, Santhoshi Bandla
Molecular Evolution Of Genes Underlying Phenotypic Differences Between Humans And Chimpanzees, Santhoshi Bandla
Legacy Theses & Dissertations (2009 - 2024)
Chimpanzees (Pan troglodytes) and bonobos (P. paniscus) are often used as models to study the genetic and morphological changes on the lineage leading to the modern humans (Homo sapiens). Results of this dissertation suggest that, in comparison to other hominoids, chimpanzees and bonobos are more derived in their relative testes sizes and promiscuous mating systems. Phylogenetic analysis of genes that might underlie increased testes size revealed that, in addition to being a sex-determining gene, SRY displays Pan-specific amino acid replacements that make it a compelling candidate as a testes-size determining gene. Strikingly, SRY and another candidate gene, DMRT3, display patterns …

Competitiveness And Addictive Behaviors : Exploring The Role Of Competitiveness And Gender In Exercise Dependence, Disordered Eating, And Alcohol Use, Holly Felicia Serrao
Legacy Theses & Dissertations (2009 - 2024)
The current study explored whether or not trait competitiveness existed as an underlying factor contributing to the higher rates of exercise dependence, disordered eating, and alcohol use among athletes. Additionally, the study examined whether certain gender differences occurred, such that the relationship between competitiveness and disordered eating would be stronger for female athletes, the relationship between competitiveness and alcohol use would be stronger for male athletes, and the relationship between competitiveness and exercise dependence would be gender neutral.

Interoceptive Fear Conditioning And Panic Disorder Ii : Clarifying The Role Of Cs-Us Discrimination, Dean Thomas Acheson
Interoceptive Fear Conditioning And Panic Disorder Ii : Clarifying The Role Of Cs-Us Discrimination, Dean Thomas Acheson
Legacy Theses & Dissertations (2009 - 2024)
Despite the role afforded interoceptive fear conditioning in learning theory accounts of panic disorder, there exists little research demonstrating such learning in humans. A recent study by Acheson and colleagues (2007) was the first to successfully demonstrate interoceptive fear conditioning in humans. The authors employed a single-cue fear learning paradigm with 20% carbon dioxide-enriched air as interoceptive conditioned (CS) and unconditioned (US) stimuli. The current study had two aims: 1) to replicate the results of Acheson et al. (2007) while improving upon the methodology, and 2) to clarify the role of CS - US discrimination in fear learning and extinction. …
Socio-Technical Processes In Interorganizational Emergency Response And Recovery Process At The World Trade Center, Bahadir Akcam
Socio-Technical Processes In Interorganizational Emergency Response And Recovery Process At The World Trade Center, Bahadir Akcam
Legacy Theses & Dissertations (2009 - 2024)
This research explores the socio-technical processes in interorganizational collaboration by extending and elaborating a generic dynamic theory. The existing generic dynamic theory offers dynamic hypotheses about causal relationships between social processes and social accumulations based on a study of interagency information integration initiatives. The current study expands this theory and elaborates upon it using interview dataset from interagency collaboration during the response and recovery process following the World Trade Center (WTC) attack on September 11, 2001. Researchers at the Center for Technology in Government interviewed 29 responders in 2002 and 2003 to explore interagency collaboration in the context of information, …

The aim of the current study was to examine the cultural adaptation process of the children of Ghanaian immigrants living in the Bronx, New York City. To this end, twenty-five Ghanaian immigrant children were interviewed. In an attempt to ascertain the extent to which these children have become acculturated to the host society and integrated into mainstream American culture, the focus of the interviews was on the impact of American culture on language, food, discipline, dress, religion, mate selection, and education. Interview participants were selected via snowball sampling. Employing a qualitative approach, I conducted face-to-face interviews consisting of open-ended questions …
Mexican Technological Universities : Pursuing Reform And New Public-Private Funding Mixes In A Non University Sector, Jorge Gamaliel Arenas-Basurto
Mexican Technological Universities : Pursuing Reform And New Public-Private Funding Mixes In A Non University Sector, Jorge Gamaliel Arenas-Basurto
Legacy Theses & Dissertations (2009 - 2024)
Although unstable funding of Mexico's public universities is a critical problem faced each year by these institutions that struggle to negotiate increments in their fiscal revenues, most public universities have still not been able to increase sizably their share of self generating revenues to mitigate, to some degree, the impact of public shortages. Different paths to financial reforms have been encouraged by Mexican authorities in order to modify the pervasive statist tradition in the funding of public universities. In the last decades, authorities have promoted funding tools aimed at modifying the incremental budgeting of most universities, encouraging them to diversify …
Opportunism And Diversity In The Lifestyle Of A Group Ii Intron, Arthur R. Beauregard
Opportunism And Diversity In The Lifestyle Of A Group Ii Intron, Arthur R. Beauregard
Legacy Theses & Dissertations (2009 - 2024)
Group II introns are mobile retroelements. They invade the cognate intron-minus gene in an efficient process known as retrohoming. They can also retrotranspose to ectopic sites at low frequency. Retrohoming occurs by the intron RNA reverse-splicing into double-stranded DNA (dsDNA) through an endonuclease-dependent pathway. However, in retrotransposition in Lactoccocus lactis, the intron inserts predominantly into single-stranded DNA (ssDNA), in an endonuclease-independent manner. Unlike in L. lactis, in Escherichia coli the Ll.LtrB intron retrotransposes frequently into dsDNA, and the process is dependent on the endonuclease activity of the intron-encoded protein. Further, the endonuclease-dependent integrations preferentially occurred around the origin and terminus …
