abstract: This study presents a structural model of coping with dating violence. The model integrates abuse frequency and solution attribution to determine a college woman's choice of coping strategy. Three hundred, twenty-four undergraduate women reported being targets of some physical abuse from a boyfriend and responded to questions regarding the abuse, their gender role beliefs, their solution attribution and the coping behaviors they executed. Though gender role beliefs and abuse severity were not significant predictors, solution attribution mediated between frequency of the abuse and coping. Abuse frequency had a positive effect on external solution attribution and external solution attribution had a positive effect on the level of use of active coping, utilization of social support, denial and acceptance. / Dissertation/Thesis / Ph.D. Counseling Psychology 2011

abstract: Lexical diversity (LD) has been used in a wide range of applications, producing a rich history in the field of speech-language pathology. However, for clinicians and researchers identifying a robust measure to quantify LD has been challenging. Recently, sophisticated techniques have been developed that assert to measure LD. Each one is based on its own theoretical assumptions and employs different computational machineries. Therefore, it is not clear to what extent these techniques produce valid scores and how they relate to each other. Further, in the field of speech-language pathology, researchers and clinicians often use different methods to elicit various types of discourse and it is an empirical question whether the inferences drawn from analyzing one type of discourse relate and generalize to other types. The current study examined a corpus of four types of discourse (procedures, eventcasts, storytelling, recounts) from 442 adults. Using four techniques (D; Maas; Measure of textual lexical diversity, MTLD; Moving average type token ratio, MATTR), LD scores were estimated for each type. Subsequently, data were modeled using structural equation modeling to uncover their latent structure. Results indicated that two estimation techniques (MATTR and MTLD) generated scores that were stronger indicators of the LD of the language samples. For the other two techniques, results were consistent with the presence of method factors that represented construct-irrelevant sources. A hierarchical factor analytic model indicated that a common factor underlay all combinations of types of discourse and estimation techniques and was interpreted as a general construct of LD. Two discourse types (storytelling and eventcasts) were significantly stronger indicators of the underlying trait. These findings supplement our understanding regarding the validity of scores generated by different estimation techniques. Further, they enhance our knowledge about how productive vocabulary manifests itself across different types of discourse that impose different cognitive and linguistic demands. They also offer clinicians and researchers a point of reference in terms of techniques that measure the LD of a language sample and little of anything else and also types of discourse that might be the most informative for measuring the LD of individuals. / Dissertation/Thesis / Ph.D. Speech and Hearing Science 2011

This dissertation involved the development of a new construct, perceived privacy breach (PPB), to evaluate how a person perceives breaches of privacy in terms of whether they perceive any exchange of information was fair or not and how they believe it will impact people whose information has been shared. This instrument assists researchers to understand how a person perceives a possible breach of privacy. The PPB instrument was created after conducting a pilot study of approximately 200 undergraduate students and testing the data for possible dimensions in an Exploratory Factor Analysis (EFA). The EFA resulted in a concise 14 item questionnaire with three dimensions: dispersion, fairness, and impact. The PPB instrument was utilized in a larger study with 285 participants after a small pilot test (n=27) to study the impact of perceptions of privacy preaches upon a person's level of concern for his or her own privacy and the effect it has on their trust in organizations to protect their privacy in relation to their usage of Internet search engines. It also studied how the combination of perceptions of privacy breaches, general privacy concern, and trust had an impact on a person's anxiety and decision to continue using online search engines. The study also theorized that a person's concern for privacy and use of search engines might result in cognitive dissonance, which might have an effect on the way people think about privacy issues. The model was analyzed using a two step process. First a confirmatory factory analysis (CFA) using the software application EQS was run on the measurement model, in which all the instruments were assessed. The perceived privacy breach instrument had a Cronbach's alpha value of .89. The structural model was run in EQS and achieved a CFI fit of .86. There was a statistically significant relationship between perceived privacy breach and privacy concern, and between privacy concern and trust. Increase in trust was shown to have an effect on technology usage attitude. Hypotheses involving cognitive dissonance showed statistically significant results in the opposite direction.

The increasing emphasis on integration among members of a supply chain has led to new mechanisms to help firms coordinate the flow of products, services, and information through the supply chain. Many studies support the importance and influence of supply chain integration on firm performance but only a few focus on factors driving the integration practices. Moreover, the role of organizational contextual factors that could influence supply chain integration has been largely overlooked. This research examines firms' internal and external drivers of supply chain integration, as well as evaluates the impact of the integration on firm performance. This study further investigates the moderating role of organizational culture, based on the dimensions of control-flexibility orientation and internal-external focus, in strengthening or weakening the relationships between supply chain integration and its antecedents. For the purpose of this study, manufacturing firms were identified as the focal firms in supply chains, and thus data was collected through a survey of 223 Indonesian-based manufacturing firms. Two informants from each firm became the respondents. Structural equation modeling was used to analyze the data, and this study confirmed the positive relationships between supply chain integration and firm performance. The results also indicated that internal driver, or specifically firms' customer orientation, triggered the initiation of supply chain integration. Other factors, such as demand uncertainty, supply uncertainty, technology uncertainty, as well as firms' anticipation of benefits, were not significantly related to the degree of supply chain integration. Furthermore, focal firms with external focus were pursuing a higher degree of supply chain integration than those with internal focus. By investigating the linkages between internal and external drivers, supply chain integration, firm performance, and organizational culture, this study attempts to contribute to the Operations Management discipline, especially to the area of supply chain management. Implications for research and practice are discussed.

abstract: This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. The participants for this study were a subsample of a nationally representative sample used in the standardization of the Woodcock-Johnson III Tests of Cognitive Abilities and the Woodcock-Johnson III Tests of Achievement, Normative Update (Woodcock, McGrew, & Mather, 2007). Participants were between 5 years old and 18 years old (N = 4721; mean of 10.98 years, median of 10.00 years, standard deviation of 3.48 years), and were 50.7% male and 49.3% female. Structural equation models supported the theoretical suggestion that broad cognitive processes play significant and specific roles in the development of mathematical skills among children and adolescents. Implications for school psychology researchers and practitioners are discussed. / Dissertation/Thesis / Ph.D. Educational Psychology 2012

The tallgrass prairie has been severely reduced in size, making restoration important to maintain communities and functions of this ecosystem. A chronosequence approach was used to determine recovery of physical and biological soil properties. The recovery models of soil properties provided information to explain the variation in total C stock of the whole soil. Recovery models also provided information to design a competition experiment based on variation in whole soil conditions with land use history. The filter framework hypothesis is a useful concept for examining tallgrass prairie restoration; the theory states only a subset of species in the region will be able to establish in a specific location due to abiotic and biotic filters. With this theory in mind, I explored the influence of whole soil conditions as affected by land use history (cultivation/restoration) and how these conditions altered plant-plant competition dynamics of a dominant grass was studied. Belowground plant biomass recovers with cessation of tillage and restoration back to prairie, providing an organic matter source for microbial populations to recover and soil macroaggregates to form. This has potential to increase C sequestration in soils and decrease nitrous oxide efflux from soils. Intact 5.5 cm dia cores were collected to a depth of 10 cm in each field to determine physical and biological soil properties. Belowground plant, microbial community, and soil structure properties were modeled to recover coinciding with an increase in total C stock of the whole soil. Structural equation modeling revealed that soil structure physically protecting organic matter explained the most variation in soil carbon sequestration with restoration. Most of the total C was contained within the macroaggregate size fraction; within this fraction most of that C is within the microaggregates within macroaggregates fraction. Soil structure is critical for recovery of soil carbon stocks and the microaggregate within macroaggregate fraction is the best diagnostic of sequestered C. ANCOVA results indicate that while the slopes of nitrous oxide efflux rates did not differ, cumulative efflux differed, though this was not related to time since restoration. Dominant grasses, such as Andropogon gerardii, can exclude subordinate species from grassland restorations. Thus, understanding changes in competition dynamics of dominant grasses could help maintain richness in grassland restorations. There may be changes in competition dynamics with whole soil conditions affected by land use history (cultivation/restoration) as plant available nutrients will decrease, microbial populations will increase, and soil structure will improve with restoration from cultivation to prairie. Using 4 soil treatments of varying land use history with four species treatments, to determine if effects are general or species specific, pairwise substitution competition experiments were conducted. Relative A. gerardii response to competition was compared among soil and species treatments using competition intensity and competition importance indices utilizing final plant biomass, relative growth rate based on maximum height, and net absolute tiller appearance rate. The experiment was conducted over 18 weeks, allowing A. gerardii to flower. A significant intensity result and significant importance results utilizing biomass measurements indicated that the 16 year restored prairie soil cause A. gerardii to be a relatively better competitor against forbs than in all other soils except for cultivated soil, likely due to positive plant-soil feedbacks. Significant importance results utilizing tiller appearance rate indicated that the cultivated and 3 year restored prairie soil caused A. gerardii to be a relatively better competitor than in the 16 year restored and never cultivated native prairie soils, likely due to changes in whole soil conditions related to land use history. There were only general soil effects, as soil treatments did not interact with species treatments. A. gerardii was a relatively better competitor against non-leguminous forbs, indicating that legumes are a better competitor for a limiting nutrient than A. gerardii or that this species is not in direct competition with legumes.
