Description
Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Description
Science, Technology, Engineering & Mathematics (STEM) careers have been touted as critical to the success of our nation and also provide important opportunities for access and equity of underrepresented minorities (URM's). Community colleges serve a diverse population and a large number of undergraduates currently enrolled in college, they are well situated to help address the increasing STEM workforce demands. Geoscience is a discipline that draws great interest, but has very low representation of URM's as majors. What factors influence a student's decision to major in the geosciences and are community college students different from research universities in what factors influence these decisions? Through a survey-design mixed with classroom observations, structural equation model was employed to predict a student's intent to persist in introductory geology based on student expectancy for success in their geology class, math self-concept, and interest in the content. A measure of classroom pedagogy was also used to determine if instructor played a role in predicting student intent to persist. The targeted population was introductory geology students participating in the Geoscience Affective Research NETwork (GARNET) project, a national sampling of students in enrolled in introductory geology courses. Results from SEM analysis indicated that interest was the primary predictor in a students intent to persist in the geosciences for both community college and research university students. In addition, self-efficacy appeared to be mediated by interest within these models. Classroom pedagogy impacted how much interest was needed to predict intent to persist, in which as classrooms became more student centered, less interest was required to predict intent to persist. Lastly, math self-concept did not predict student intent to persist in the geosciences, however, it did share variance with self-efficacy and control of learning beliefs, indicating it may play a moderating effect on student interest and self-efficacy. Implications of this work are that while community college students and research university students are different in demographics and content preparation, student-centered instruction continues to be the best way to support student's interest in the sciences. Future work includes examining how math self-concept may play a role in longitudinal persistence in the geosciences.

Description
The high rate of teacher turnover in the United States has prompted a number of studies into why teachers leave as well as why they stay. The present study aims to add to that knowledge specifically regarding why teachers choose to stay at urban schools. Several reasons teachers in general choose to stay have been identified in previous studies including faith in their students, continuing hope and sense of responsibility, and love among others. The importance of such a study is the possibility of designing programs that reinforce teacher success through understanding the personal and professional reasons teachers choose to stay. Getting teachers to stay is important to the nation's goal of providing equity in science education to all children. Important to this research is an understanding of motivational theories. Already a challenge in the over-busy modern world, the ability to self-motivate and motivate others is of particular importance to teachers in urban schools as well as teachers struggling against restrictive budgets. Studies have shown teachers extrinsically motivated will need external rewards to encourage them while teachers who are intrinsically motivated will have their own internal reasons such as satisfaction in contributing to the future, self-actualization, or the joy of accomplishment. Some studies have suggested that teachers who decide to remain teaching tend to be intrinsic motivators. Unfortunately, the environment in most Western country educational systems presents a challenge to achieving these intrinsic goals. As a result, self-determination theory should play a significant role in shaping educational programs. The following study examined the perspectives of secondary school science teachers, specifically regarding why they opted to remain within the classroom in urban districts. It was conducted utilizing interviews and surveys of teachers working within urban school districts in Arizona and California. The sample consisted of 94 science teachers. More than half of the participants were White females and 36 percent of them had been teaching for more than 15 years. Participation in the study was based on self-selected volunteerism. Survey questions were based on self-determination theory and used Likert scale responses. Follow-up audiotaped interview requested information regarding identity and their social interaction within the urban settings. The survey responses were analyzed using SPSS for descriptive statistics, one-way ANOVA, and linear regression. The results of this study provide insight on what works to motivate science teachers to continue teaching in less than ideal school settings and with such high bureaucratic impediments as standardized testing and school rating systems. It demonstrates that science teachers do seem to be intrinsically motivated and suggests some areas in which this motivation can be fostered. Such results could help in the development of teacher support groups, professional development programs, or other programs designed to assist teachers struggling to deal with the specific problems and needs of inner city school students.

Description
Problem solving is a crucial skill needed to accomplish everyday tasks and overcome potential obstacles. One way to measure individual differences in problem solving ability is through performance differences on multiply-constrained problem solving tasks. Multiple cognitive processes are involved in multiply-constrained problem solving. An individual uses prospective metacognitive monitoring judgments to gauge future allocation of resources before engaging in the necessary semantic search. Problem solvers also vary in their semantic search strategies, and use either an active analytical strategy or a passive insight strategy to arrive at asolution. Prospective metacognitive monitoring judgments and solution strategies are two aspects of the problem solving process that occur at specific points in the process while motivation influences problem solving throughout the process. The goal of this study is to examine prospective metacognitive judgments, problem solving accuracy, solution strategy, and motivation in multiply-constrained problem solving. Motivation was manipulated using a performance based monetary incentive. Participants self reported prospective Feeling-of-Knowing judgments after brief exposure to the problem, and solution strategy ratings after each problem. No significant differences were found to support the effect of motivation on problem solving accuracy, prospective metacognitive judgments, relative accuracy, or solution strategies. Significant differences were found between groups when comparing the number of problems skipped, indicating that participants were sensitive to the incentive structure. The findings suggest that motivation may not be an overarching mediator in multiply-constrained problem solving or problem solving may require a specific type of incentive structure to increase accuracy. However, little is known in the research literature about the type of incentive structure needed to consistently increase individual motivation.

Description
Self-control has been shown to predict both health risk and health protective outcomes. Although top-down or “good” self-control is typically examined as a unidimensional construct, research on “poor” self-control suggests that multiple dimensions may be necessary to capture aspects of self-control. The current study sought to create a new brief survey measure of top-down self-control that differentiates between self-control capacity, internal motivation, and external motivation. Items were adapted from the Brief Self-Control Scale (BSCS; Tangney, Baumeister, & Boone, 2004) and were administered through two online surveys to 347 undergraduate students enrolled in introductory psychology courses at Arizona State University. The Self-Control Motivation and Capacity Survey (SCMCS) showed strong evidence of validity and reliability. Exploratory and confirmatory factor analyses supported a 3-factor structure of the scale consistent with the underlying theoretical model. The final 15-item measure demonstrated excellent model fit, chi-square = 89.722 p=.077, CFI = .989, RMSEA = .032, SRMR = .045. Despite several limitations including the cross-sectional nature of most analyses, self-control capacity, internal motivation, and external motivation uniquely related to various self-reported behavioral outcomes, and accounted for additional variance beyond that accounted for by the BSCS. Future studies are needed to establish the stability of multiple dimensions of self-control, and to develop state-like and domain-specific measures of self-control. While more research in this area is needed, the current study demonstrates the importance of studying multiple aspects of top-down self-control, and may ultimately facilitate the tailoring of interventions to the needs of individuals based on unique profiles of self-control capacity and motivation.

An investigation of academic achievement and achievement motivation in children with cystic fibrosis
Description
Cystic Fibrosis, one of the most severe childhood life-shortening illnesses, places demands on a child's life conceivably interfering with his or her academic success. It is possible that the medically related activities in which individuals with CF partake interfere with academic activities and the motivation, specifically beliefs, expectancies, and values held, toward those activities. These issues encouraged the investigation of academic achievement and achievement motivation in children with CF through exploration of three research questions. Question one concerns differences in academic achievement between children with CF and a healthy comparison group for 1) reading and 2) math. Question two explored differences in aspects of motivation including ability beliefs, outcome expectancies, and task values between the groups for the two academic subjects. Finally, question three examined the relationship between motivational components and academic achievement. Evidence is provided for differences in math achievement between the two groups. Differences in motivation between children with CF and healthy children remain unsubstantiated.

Description
In the United States, recreational female golfers give up golf at twice the rate of recreational male golfers. This study explored the causal attributions of 240 recreational golfers after a practice session at a public golf facility. Attributions can be adaptive or maladaptive after a performance and can influence subsequent motivation to engage in a similar task again. It was hypothesized that male and female golfers would make significantly different attributions for their performance and that female golfers' attributions would be maladaptive. As the attrition rate for female golfers is highest in the first five years, it is also hypothesized that women's attributions will become more adaptive over time and that attributions will be moderated by the number of years playing golf and perceived level of success. A survey was used to measure golfers' attributions and general questions provided data for the number of years playing golf and gender. The subscales in the attribution survey were internal control, external control and stability. Attributions are adaptive or maladaptive depending on the level of perceived success, so success of the practice performance was collected. The hypothesis that recreational female golfers make significantly different attributions than recreational male golfers was supported only by the external control sub-scale. Female golfers perceived their performance as significantly less successful than male golfers. Considering this perception of success, women golfers' attributions were maladaptive. The hypothesis that women golfers' attributions become more adaptive over time was supported. Time playing golf predicted a significant amount of variance for internal attributions of female golfers. However, the hypothesis that attributions will be moderated by the number of years playing golf and perceived success was not supported.

With the help of some Information Measurement Theory (IMT), Kashiwagi Solutions Model (KSM), and deductive logic background, supply chain managers can start utilizing a new way to effectively and efficiently negotiate contracts. Developed by Dr. Dean Kashiwagi, the Best Value Approach has been 98% successful with over 1,800 projects for the past 20 years. The process gives vendors/suppliers the power to use their expertise. In return for not having to follow the rules set by the client/buyer, the vendor must show documentation and plans of risk management, value added processes, and metrics.

Description
Self-control has been shown to be an important influence behind a variety of risk and protective behaviors, such as substance abuse. Although prior research points to the existence of multiple dimensions of self-control, this concept is not consistently defined and frequently only studied as a conglomerate in clinical research. The current study sought to examine how two experimental manipulations of subcomponents of self-control (motivation and self-efficacy) affect real-world consumptive behavior after accounting for executive function. Additionally, the validity and reliability of a brief state survey measure of perceived self-control capacity, internal motivation, and external motivation was tested. The goal was to examine how basic scientific principles involved in self-control translate into clinically relevant behaviors, which may inform understanding of momentary lapses in self-control behavior, potentially leading to novel prevention and intervention efforts. 94 college students completed a 1-2 hour laboratory protocol during which they completed survey and laboratory-based tasks of self-control and related behaviors, executive function, and ad libitum alcohol consumption. Results showed that the self-efficacy manipulation successfully increased perceived self-control capacity, although this did not lead to a significant reduction in consumption. The motivation manipulation neither increased motivation nor reduced consumption in this sample. However, the brief state survey measure of self-control subcomponents demonstrated strong test-retest reliability and distinction from trait self-control, demonstrating its viability for use in future research. By elucidating the relationships between specific mechanisms of self-control, laboratory-based tasks and manipulations, and real-world consumptive behaviors, prevention and intervention efforts for problems such as alcohol abuse may be tailored to the needs of the individual and made more impactful and cost-effective.
