This study presents a qualitative analysis of principals' perceptions of the relationship among principal preparation programs, professional development and instructional leadership confidence in one urban school division in Virginia. Levine (2005) argued that the principal has a salient effect on the instructional programs within schools, and the preparation and professional development of the principal affects the degree to which they maintain and improve instruction. To examine principal perceptions on feelings of confidence toward instructional leadership, four research questions were investigated: What are principals' perceptions concerning the instructional confidence needed to lead schools in one school division? What are principals' perceptions regarding the coursework undertaken in their preparation program and the associated confidence developed for instructional leadership in one school division? What are principal perceptions concerning post-graduate professional development and the associated confidence developed for instructional leadership in one school division? What type of additional training do principals believe would enhance their confidence toward instructional leadership in one school division? The researcher sought to ascertain principal perceptions concerning the construct, instructional leadership efficacy, based on their academic training and professional development. The findings were as follows: a) interviewed principals in one urban school division described instructional leadership efficacy in terms of one's capacity to provide instructional leadership and one's know how to foster home-school relations; b) interviewed principals in one urban school division believe that the principal must act as an instructional leader to facilitate learning in the building; c) interviewed principals from one urban school division reported that the course of greatest significance to instructional leadership was school law; d) interviewed principals from one urban school division were unable to identify the most beneficial professional development in terms of that which is needed to be the instructional leader; e) there was no recommendation for specific coursework in the principal preparation program that was supported by the majority of the interviewed principals. / Ed.

In this dissertation, I investigate how differences in the manner via which individuals pursue goals (judging effort from outcome or outcome from effort) influences expectations (effort vs. outcome). In particular, I focus on the role of self-efficacy, and show that when individuals focus on outcomes, they take self-efficacy into consideration when assessing how much effort is needed. However, when focusing on effort, individuals do not take self-efficacy into consideration when making judgments of outcomes. Thus, I find that irrespective of differences in self-efficacy, individuals expect similar outcomes when effort invested is the same. I report findings from six studies, and discuss theoretical and managerial implications. / Ph. D.

This study was conducted to identify combinations of self-efficacy enhancing strategies and language learning strategies and to align them with Gagne's Nine Events of Instruction (1985). If worked together, these combinations can be used by educators to encourage students studying abroad to acquire second language skills in a shorter amount of time. This design and development study conducted model research through model development and model validation. The considerations were created and supported by current research in the literature and validated by experts from these three areas and revised based on their recommendations. / Doctor of Philosophy / This study was conducted to establish instructional considerations that combine strategies that show, in the literature, to have an effect on second language acquisitions such as self-efficacy enhancing strategies and language learning strategies and apply these strategies in everyday instructions using Gagne's Nine Events (1985). It is hoped that the proposed considerations, after revised by expert reviewers, can be utilized when teaching second language learning skills to international students who seek higher education degrees and have limited time to acquire these skills. The considerations were created and supported by current research in three areas of the literature: self-efficacy enhancing strategies, language learning strategies, and Gagne's Nine Events (1985) and validated by experts from these three areas.

Adult marijuana users seeking treatment (N = 291) were randomly assigned to 3 treatment conditions: 1) a cognitive-behavioral relapse prevention support group (RPSG), 2) individualized assessment and advice group, and 3) delayed treatment control group. The purpose of this study was to examine the relationship between psychological distress, self-efficacy, and marijuana use. Measures of marijuana use, psychological distress, situational self-efficacy, coping self-efficacy, temptation to use, and frequency of encountering situations were used. Only a portion of the hypotheses were supported. Psychologically distressed individuals had lower self-efficacy for psychologically distressing (PD) situations as opposed to non-psychologically distressing (NPD) situations. Participants had lower self-efficacy for NPD situations than PD situations. The RPSG condition did not have the hypothesized effect on self-efficacy for PD situations. / Master of Science

With post-bloom chemical fruit thinning responses being heavily influenced by tree carbohydrate reserves and weather conditions, there is a need for alternative thinning practices such as chemical blossom thinning in the Mid-Atlantic apple growing region. This project sought to 1) evaluate timing strategies for lime sulfur + stylet-oil blossom thinning sprays and 2) screen chemical agents for their suitability and efficacy as blossom thinners. In the first study, two 'Gala'/'M.9' blocks in different states (North Carolina and Virginia) were utilized in 2019 to compare between pollen tube growth model-guided blossom thinning sprays and those that are based on fixed time intervals between the initial application and subsequent thinning sprays. It was generally found that model-guided blossom thinning sprays and sprays applied at 20% open bloom and 48 hours after reduced fruit set, crop load, and improved fruit weight. In the second study, a 'Honeycrisp'/'B.9' and 'Cripps Pink'/'M.9' apple block in Virginia were used in 2018 and 2019 to evaluate multiple chemical agents with and without stylet-oil. Most of the treatments under-thinned compared to untreated control trees. However, it was determined that ammonium thiosulfate with and without stylet-oil was the most effective thinning agent. Potassium bicarbonate + stylet-oil was observed to cause excessive fruit russeting and phytotoxicity. This project demonstrated that optimum apple crop loads can be obtained if lime sulfur + stylet-oil blossom thinning sprays are applied at the proper time, and that multiple chemical agents offer potential use for chemical blossom thinning in the Mid-Atlantic region / Master of Science in Life Sciences / For apple trees to produce high quality fruit, a proportion of the flowers and/or fruit must be removed in a practice known as "thinning". Chemical blossom thinning is a relatively new method of thinning in the Mid-Atlantic apple growing region. This project sought to 1) evaluate spray timing of blossom thinning sprays and 2) evaluate different chemicals for their suitability in blossom thinning. In the first study, two 'Gala' apple orchards in two states (North Carolina and Virginia) were utilized in 2019 to compare a computer model-guided spray timing to structured spray timings based on the amount of time between the first and second sprays. It was found that the model-guided sprays, and sprays occurring once 20% of the blossoms had opened and reapplied 48 hours after, were the most effective in thinning the flowers. In the second part of the study, a 'Honeycrisp' orchard and a 'Cripps Pink' orchard in Virginia were used in 2018 and 2019 to evaluate different chemicals for their potential as blossom thinners. Unfortunately, most of the treatments did not achieve sufficient thinning results compared to untreated trees. However, it was determined that ammonium thiosulfate with and without stylet-oil was the most effective thinning chemical. Potassium bicarbonate with stylet-oil was found to cause excessive injury to the fruit and foliage. This project demonstrated that blossom thinning can be effective when the sprays are applied at the correct time and that multiple chemical agents offer potential for blossom thinning in the Mid-Atlantic.

The empirical literature on goal orientation is ambiguous in relation to the supposed effects of performance goal orientation (PGO) on goal setting and performance. In an attempt to clear up this issue it was hypothesized based on Carol Dweck's (1989) theoretical framework that dispositional performance goal orientation would interact with self-efficacy in their effect on level of self-set goal and performance, such that the relationship between PGO and goals (and performance) would be positive for individuals high on self-efficacy, while negative for individuals low on self-efficacy. Furthermore it was predicted that learning goal orientation would be positively related to both goals and performance. In both cases it was predicted that goals would serve as a mediator between the goal orientations and performance. The hypotheses were tested using a diverse sample (N = 146) of Icelandic job applicants on their way to a job interview. No support for the hypotheses was found. Potential causes for the non-findings are identified and analyzed and the status of the goal orientation construct is discussed. / Master of Science

The present studies attempted to clarify the constructs of self-efficacy and outcome expectancies in relation to college student drinking. In study 1, heavy-drinking college students were asked for efficacy judgments for limiting their heavy-drinking for increasing periods of time (e.g. 1 day, 1 week, 1 month, etc.). Students were also asked for efficacy judgments for throwing a basketball into a hoop from increasing distances (e.g. 5 feet, 10 feet, 15 feet). Hypothetical incentives were offered to change efficacy ratings for the first tasks on each hierarchy (limiting drinking and basketball) to which the participant had responded with a negative efficacy judgments. Hypothetical incentives were also offered for the most difficult task on each hierarchy. As predicted, students changed efficacy ratings for limiting drinking much more frequently. Additionally, heavy-drinking college students indicated that money persuaded them to alter their efficacy judgments for limiting drinking, but lack of ability predominated as the reason for not altering basketball task efficacy. In study 2, the relationship between ability judgments, willingness, and outcome expectancies was explored by manipulating the wording of questionnaires presented to heavy-drinking college students. Results indicated that ability judgments were higher than willingness judgments for limiting drinking. Willingness appeared to be related to expected positive and negative effects of consuming alcohol. Principle components analysis indicated that ability and willingness were distinct constructs. Results of both studies are discussed in terms of the ongoing debate between Albert Bandura and Irving Kirsch and the need for a more clarity regarding efficacy and its measurement. / Master of Science

The present study set out to examine the role of learning and performance goal orientation on goal setting and self-efficacy. More specially, the present study attempted to verify the results of the effects of learning goal orientation and to clarify the role of performance goal orientation. In addition, the role of self-efficacy and the possibility of an interaction between learning goal orientation and performance goal orientation were also examined. While the present study did not find a significant impact of dispositional goal orientation on any motivational variables examined, relatively strong support was found for the impact of situational learning and performance goal orientation on both goal choice and self-efficacy. As expected, learning goal orientation was a predictor of goal choice and self-efficacy, in that individuals who display a strong learning goal orientation set higher goals and demonstrate increased levels of self-efficacy. Contrary to past research, performance goal orientation was found to be an extremely strong, positive predictor of both goal choice and self-efficacy. The presence of this positive relationship could indicate the possibility of a potential task moderator. Although strong support was found for the independent effects of goal orientation on goal choice and self-efficacy, partial mediation by self-efficacy of learning goal orientation and goal choice was not found. Similarly, the results obtained in the present study did not provide evidence of an interaction between the two goal orientation dimensions in predicting either goal choice or self-efficacy. Taken as a whole, the present study does provide support for the importance of learning and performance goal orientation in the formation of self-set goals and one's level of self-efficacy. / Master of Science

Self-efficacy for avoiding alcohol use predicts alcohol use after treatment. However, self-efficacy predicts outcome differentially depending on whether ratings are made before or after treatment. In order to increase the predictive validity of self-efficacy judgments, the hypothesized sources of self-efficacy were examined in the current study utilizing a college student population. Self-efficacy ratings for avoiding heavy drinking before and after self-monitoring of drinking behavior were examined in order to understand whether careful examination of current behavior would result in more informed self-efficacy judgments. Participants (N = 135) completed questionnaires that assessed self-efficacy, drinking behaviors, alcohol expectancies, and perceived normative alcohol use. Participants were assigned to either the control or self-monitoring condition. Self-monitors recorded drinking behaviors during the four weeks after the baseline assessment. All participants returned for a follow-up assessment four weeks later. Consistent with predictions based on social cognitive theory, heavy drinking, positive alcohol expectancies, and perceived norms of use were inversely related to self-efficacy. Hierarchical multiple regression analyses indicated that self-monitoring did not lead to stronger relationships between source variables and self-efficacy. Individuals who appeared to be overconfident in their self-efficacy judgments at baseline did not make more accurate ratings as a result of self-monitoring. Results from this study highlight potential sources of information individuals use in making self-efficacy judgments. / Master of Science

The purpose of this study was to explore whether overweight college dieters, engaged in self-structured weight loss efforts, experienced physical symptomatology that has previously been associated with severe caloric restriction. The relationships between physical symptomatology, self-efficacy, and future dieting behavior were also investigated. Forty college students (21 female, Mage = 19.58 years, SD= 1.85) self-reported caloric intake and completed self-efficacy measures and physical symptom reports for three weeks. Results indicated that weekly physical symptom reports were not associated with caloric deficit and did not predict future dieting behavior. Physical symptoms were negatively related to self-efficacy for dieting and exercise as predicted, but in several analyses, higher self-efficacy actually predicted less calorie restriction. Physical symptom reports were predicted by trait neuroticism and neuroticism was also significantly and negatively associated with eating and exercise self-efficacy. Results raised issues about the accuracy of caloric restriction reporting and suggested that personality characteristics may have an important impact on an individual's perception of dieting experiences and levels of self-efficacy during dieting. / Master of Science
