Miranda Reasoning and Competent Waiver Decisions: Are Models of Legal Decision Making Applicable?

Miranda Reasoning and Competent Waiver Decisions: Are Models of Legal Decision Making Applicable?

Date: May 2013
Creator: Blackwood, Hayley L.
Description: Miranda understanding, appreciation, and reasoning abilities are essential to courts' determinations of knowing and intelligent Miranda rights waivers. Despite the remarkable development of Miranda research in recent decades, studies have generally focused on understanding and appreciation of Miranda rights, but have not examined Miranda reasoning and waiver decisions. Therefore, examining the nature of defendants' decisional capacities constitutes a critical step in further developing theoretical and clinical models for competent Miranda waiver decisions. The current study evaluated Miranda waiver decisions for 80 pretrial defendants from two Tulsa-area Oklahoma jails. Previously untested, the current study examined systematically how rational decision abilities affect defendants' personal waiver decisions. Components from general models of legal decision making, such as decisional competence and judgment models, were examined to determine their applicability to Miranda waiver decisions.

Miscegenated Narration: The Effects of Interracialism in Women's Popular Sentimental Romances from the Civil War Years

Miscegenated Narration: The Effects of Interracialism in Women's Popular Sentimental Romances from the Civil War Years

Date: May 2011
Creator: Beeler, Connie
Description: Critical work on popular American women's fiction still has not reckoned adequately with the themes of interracialism present in these novels and with interracialism's bearing on the sentimental. This thesis considers an often overlooked body of women's popular sentimental fiction, published from 1860-1865, which is interested in themes of interracial romance or reproduction, in order to provide a fuller picture of the impact that the intersection of interracialism and sentimentalism has had on American identity. By examining the literary strategy of "miscegenated narration," or the heteroglossic cacophony of narrative voices and ideological viewpoints that interracialism produces in a narrative, I argue that the hegemonic ideologies of the sentimental romance are both "deterritorialized" and "reterritorialized," a conflicted impulse that characterizes both nineteenth-century sentimental, interracial romances and the broader project of critiquing the dominant national narrative that these novels undertake.

Misinformation About the Misinformation Effect

Misinformation About the Misinformation Effect

Date: August 2012
Creator: Halvorsen, Lars I.
Description: This study partially replicated the research of Cook, Kwak, Hoffman, & Loftus where they examined post-event activities that induces subjects to pick a wrong person in a forced choice identification procedure. The goal was to investigate if providing a neither option to a match to sample task increases the accuracy of responding. Subjects were asked to study three faces for 10 seconds, after which they were asked to pick out the faces in a forced choice setting where two other faces were presented. Later the subjects were asked to pick out faces in a setting in which they could use a neither option. Results indicated that a generalization effect occurs when identifying faces and the effect is seen as subjects choosing the wrong face. This suggests that when using faces with some similar features in a lineup setting the procedure may cause the subject to pick the wrong person.

Missed Opportunities: Examining The LiteracyExperiences Of African American Students Displaced By Hurricane Katrina.

Missed Opportunities: Examining The LiteracyExperiences Of African American Students Displaced By Hurricane Katrina.

Date: December 2011
Creator: Pollard, Tamica McClarty
Description: The purpose of this study was to examine how five African American middle school students, who were displaced by Hurricane Katrina represent their literacy experiences before, during, and after their displacement. Specifically, the two research questions were: (a) What are the stories that these middle school students tell about their lives, before, during, and after their displacement, and (b) What do their stories reveal about their literacy experience before, during, and after their displacement? Narrative Inquiry was the chosen methodology for the study, which allowed the participants to tell their experiences from a first-person perspective. It also encouraged the participants to reflect upon these experiences, in order to give meaning to their thoughts and emotions. Employing a critical lens and perspective, I constructed a narrative profile for each participant, which was then analyzed using these methods. Each narrative profile detailed the literacy experiences of the participants before Hurricane Katrina, during the transition period, and current literacy experiences now that the participants are resettled and attending school in the host city. These data were supplemented by archival data such as report cards, individual education plans (IEPs), and Texas Assessment of Knowledge and Skills (TAKS) scores. Data analysis of the five participants’ ...

Missing Data Treatments at the Second Level of Hierarchical Linear Models

Missing Data Treatments at the Second Level of Hierarchical Linear Models

Date: August 2011
Creator: St. Clair, Suzanne W.
Description: The current study evaluated the performance of traditional versus modern MDTs in the estimation of fixed-effects and variance components for data missing at the second level of an hierarchical linear model (HLM) model across 24 different study conditions. Variables manipulated in the analysis included, (a) number of Level-2 variables with missing data, (b) percentage of missing data, and (c) Level-2 sample size. Listwise deletion outperformed all other methods across all study conditions in the estimation of both fixed-effects and variance components. The model-based procedures evaluated, EM and MI, outperformed the other traditional MDTs, mean and group mean substitution, in the estimation of the variance components, outperforming mean substitution in the estimation of the fixed-effects as well. Group mean substitution performed well in the estimation of the fixed-effects, but poorly in the estimation of the variance components. Data in the current study were modeled as missing completely at random (MCAR). Further research is suggested to compare the performance of model-based versus traditional MDTs, specifically listwise deletion, when data are missing at random (MAR), a condition that is more likely to occur in practical research settings.

Mist and Microstructure Characterization in End Milling Aisi 1018 Steel Using Microlubrication

Mist and Microstructure Characterization in End Milling Aisi 1018 Steel Using Microlubrication

Date: August 2013
Creator: Shaikh, Vasim
Description: Flood cooling is primarily used to cool and lubricate the cutting tool and workpiece interface during a machining process. But the adverse health effects caused by the use of flood coolants are drawing manufacturers' attention to develop methods for controlling occupational exposure to cutting fluids. Microlubrication serves as an alternative to flood cooling by reducing the volume of cutting fluid used in the machining process. Microlubrication minimizes the exposure of metal working fluids to the machining operators leading to an economical, safer and healthy workplace environment. In this dissertation, a vegetable based lubricant is used to conduct mist, microstructure and wear analyses during end milling AISI 1018 steel using microlubrication. A two-flute solid carbide cutting tool was used with varying cutting speed and feed rate levels with a constant depth of cut. A full factorial experiment with Multivariate Analysis of Variance (MANOVA) was conducted and regression models were generated along with parameter optimization for the flank wear, aerosol mass concentration and the aerosol particle size. MANOVA indicated that the speed and feed variables main effects are significant, but the interaction of (speed*feed) was not significant at 95% confidence level. The model was able to predict 69.44%, 68.06% and 42.90% of ...

Mist Characterization in Drilling 1018 Steel

Mist Characterization in Drilling 1018 Steel

Date: August 2012
Creator: Cole, Ian
Description: Minimum quantity lubrication replaces the traditional method of flood cooling with small amounts of high-efficient lubrication. Limited studies have been performed to determine the characteristics of mist produced during MQL. This study investigated the mist concentration levels produced while drilling 1018 steel using a vegetable based lubricant. ANOVA was performed to determine whether speed and feed rates or their interactions have a significant effect on mist concentration levels and particle diameter. It was observed that the concentration levels obtained under all four speed and feed rate combinations studied exceeded the current OSHA and NIOSH standards.

A Mixed Method Analysis of Undergraduate Student-run Public Relations Firms on U.S. College Campuses

A Mixed Method Analysis of Undergraduate Student-run Public Relations Firms on U.S. College Campuses

Date: August 2010
Creator: Maben, Sarah Kathleen
Description: Student-run public relations firms are part of collegiate public relations pedagogy, and this study used a mixed-method approach to analyze such firms on U.S. campuses. A listing of campuses with student-run firms was created as part of this study. Through an online survey questionnaire, advisers from 55 of the 119 student-run firms provided data about firm characteristics and observations about student learning and career development. Multiple correspondence analyses was used to see if the firms grouped into clusters and somewhat aligned with previous research by Lee Bush in 2009. Firms clustered into four groups, with the fourth group representing a mix of the other three. One additional finding was that firm characteristics are more similar than dissimilar even when comparing firms of varying years in operation. Analysis of variance to compare characteristics between different types of firms revealed that one type of firm tended to employ students at a higher average number of hours per week (F = 6.61, eta squared=0.16) and one was more likely to be accredited by the Accrediting Council on Education in Journalism and Mass Communications (F = 3.71, eta squared=0.13). Advisers reported mostly positive reflections on observed transformations they see in their student workers and ...

A Mixed-Methods Approach to the Experiences of Non-Offending Parents of Children who have Experienced Sexual Abuse Participating in Child Parent Relationship Therapy (CPRT)

A Mixed-Methods Approach to the Experiences of Non-Offending Parents of Children who have Experienced Sexual Abuse Participating in Child Parent Relationship Therapy (CPRT)

Date: August 2010
Creator: West, Brooke E.
Description: When a child has been sexually abused, the non-offending parent and child may benefit from an intervention aimed at enhancing the parent child relationship. This mixed-methods study examined the process of child parent relationship therapy (CPRT) with non-offending parents of children who had been sexually abused. One purpose of the present study was to examine change in parent-child relationship, child behavior, and parent empathy of non-offending parents whose children have been sexually abused after participation in CPRT. A secondary purpose of this study was to explore subjective experiences of non-offending parents who participate in CPRT. Participants (N = 8) completed 11 weeks of CPRT in either Spanish speaking (n = 4) or English speaking (n = 4) groups. All participants completed pretest and posttest instruments including Child Behavior Checklist, Parenting Stress Index, and Measurement of Empathy in Adult-Child Interaction. Pretest and posttest means were reported but because of small sample size, only descriptive statistics are reported. Possible trends in pretest/posttest mean scores of the quantitative instruments are discussed. All participants also completed a post semi-structured interview to account for the experience of participants qualitatively. Analysis of the qualitative data revealed enhanced parent-child relationships, improved communication, greater acceptance, positive parental internal ...

A Mixed-methods Study Investigating the Relationship Between Media Multitasking Orientation and Grade Point Average

Date: August 2012
Creator: Lee, Jennifer
Description: The intent of this study was to examine the relationship between media multitasking orientation and grade point average. The study utilized a mixed-methods approach to investigate the research questions. In the quantitative section of the study, the primary method of statistical analyses was multiple regression. The independent variables for the study were media multitasking orientation, gender, age, and income. The dependent variable for the study was grade point average. Three out of four independent variables, namely, media multitasking orientation, gender and age were statistically significant predictors of grade point average. In the qualitative section of the study, seven participants were interviewed to determine how individual differences in media multitasking orientation manifest themselves in academic settings.
