In this thesis, the root-locus theory for a class of diffusion systems is studied. The input and output boundary operators are co-located in the sense that their highest order derivatives occur at the same endpoint. It is shown that infinitely many root-locus branches lie on the negative real axis and the remaining finitely many root-locus branches lie inside a fixed closed contour. It is also shown that all closed-loop poles vary continuously as the feedback gain varies from zero to infinity.

There are many aspects which must be taken into consideration when studying individuals’ need of exercise. The study investigates if impulsivity and Health Locus of Control affect the continuity of physical practise. The main presumption was that individuals with high impulsivity, high Powerful Others and high Chance Health Locus of Control, would have a significantly harder time to maintain a continuous physical activity. The survey used two standardized tests to measure impulsivity and Health Locus of Control and in order to be able to measure the insensitivity and the periodicity of physical exercise, a test was developed by the authors. 164 students, 84 female and 80 male, from Växjö University and Kalmar University College participated. The results showed no correlation between impulsivity and Health Locus of Control. A correlation between periodicity and individuals with high Internal Health Locus of Control was discovered.

This study discussed the relationships among employee personality, self-directed learning, and work performance. Samples are from people who serve in businesses, answer questionnaires with four main aspects, including Internal-External Scale, Self-Directed Learning Readiness Scale, Performance, and background data. The analysis results showed the following findings: 1. The differences of self-directed learning due to different personal background. a. Sex, age, education, department, level, work experience do not show significant differences on self-directed learning. b. The middle and high level manager are higher self-directed learning. c. People who had training in the past year are higher self-directed learning. d. People who had training or advanced study out of their own needs before are higher self-directed learning. 2. People with internal locus of control are higher self-directed learning. 3. People with internal locus of control have better performance. 4. People who are efficient and autonomous learner have better performance. 5. Employee¡¦s self-directed learning is influenced by locus of control, and it further influences performance. 6. Employee¡¦s self-directed learning is not influenced by his/her management level, and it won¡¦t influence performance further. 7. Employee¡¦s self-directed learning is influenced by his/her attending training in the last year, and it further influences performance. 8. Employee¡¦s self-directed learning is not influenced by his/her experience having training or advanced study out of his/her own needs before, and it won¡¦t influence performance further. According the findings, this research suggests: 1. Business can use personality measurements and Self-Directed Learning measurements as tools of selection. 2. Business should give employees more autonomy and resources assistance in the human development programs. 3. Business should give employees developmental opportunities in equality. 4. Employees should have the attitude being responsible to their own learning.

Research has established locus of control as a strong trait-level predictor of health and well-being and indicates that individuals with a greater sense of internal control benefit from healthier outcomes across a broad range of domains. To date, however, little research has investigated the potential malleability and state-level functioning of locus of control. Drawing from social learning theories, it was predicted that locus of control would vary on a daily basis and further that this variation would be influenced by daily hassles and anxiety. Additionally, an individual’s trait-level of internal locus of control was expected to moderate this association. The current study consists of 58 couples expecting their first child. Couples were asked to independently complete three weeks of daily diaries during their third trimester. Diaries assessed daily feelings of control, anxiety, and number of hassles encountered. Once reliable daily variation of locus of control was established, within-person analyses revealed a negative relationship such that on a day when an individual reported more anxiety or more hassles, that individual also reported feeling less control than on an average day. Further analyses revealed that an individual’s trait-level of internal control influenced this association such that, overall, those individuals with a higher trait-level of internality maintained higher levels of daily control in the face of hassles and anxiety. These findings extend prior research by providing a better understanding of locus of control and suggest important implications for efforts aimed at improving health and well-being. / text

This study addressed the possible change in young adult attitudes toward family dynamics due to the shift from traditionalism to egalitarianism in recent decades. More specifically, it sought to explore young adult perceptions' of their parents' relational ideology (e.g., degree of traditionalism), and whether young adults perceived their relational ideology to be similar to their parents' ideology. It was predicted that high levels of traditionalism in young adults would be associated with low levels of relational efficacy, as defined by conflict styles and feelings of internal control over relationships. Social cognitive theory (Bandura, 2001) posits that children learn behavior modeled by parents, particularly behaviors that are rewarded. Hence, with the increase in more egalitarian attitudes modeled by parents, this study sought to determine the extent to which young adults are now acquiring and implementing primarily egalitarian rather than traditional attitudes. A path analysis revealed significant associations between parents' degree of traditionalism and offspring traditionalism, as well as significant associations between parents' degree of traditionalism and their distributive and integrative conflict styles. Further, young adult conflict strategies were associated with parents' conflict strategies, and were significantly associated with their internal locus of control. High levels of traditionalism in young adult women were negatively associated with their internal locus of control and positively associated with their psychological distress. It appears that women perceived their parents as more egalitarian, and used conflict styles more conducive to egalitarian relationships relative to men.

The purpose of this study was to examine control beliefs and their role in the different ways victims cope with burglary. Two studies were conducted. In the first study, participants were college students who had been burglarized within the previous year. The volunteers were men and women between the ages of 19 and 37 (N=61). The participants completed Levenson's (1981) locus of control scale. The following week, in order to assist recall, the participants viewed a 2-minute video that depicted a residential burglary in progress. Immediately following the video, they completed a coping measure, situational appraisals of control measure, and importance of outcome measure. The second study was a conceptual replication of the first study and therefore followed the same procedures. However, in order to assess locus of control prior to victimization, participants were male and female college students (N=102) who had never been burglarized (experimentally induced victims). Zero-order correlations, discriminant analysis, and hierarchical multiple regression were used to examine the main, mediating, and moderating effects of locus of control, importance of outcome, situational appraisals of control, and gender on coping functions. Because previous research has found gender differences in reaction to criminal victimization, i t was hypothesized that the influence that gender has on coping results from an individual's locus of control orientation. It was also expected that the direction or strength of the locus of control and coping relation would be influenced by an individual's gender and by how much importance he or she attached to the victimization experience. In both the victim group and experimentally induced victim group, emotion-focused coping was significantly predicted by gender, locus of control, importance of outcome, and situational appraisals of control. However, problem-focused coping was significantly predicted by gender, locus of control, importance of outcome, and situational appraisals of control for the victim group only. Locus of control did not influence the gender and coping relation. The results indicated that in both groups men who held strong powerful others locus of control beliefs used less emotion-focused coping. In contrast, in the burglary victim group, women who held strong powerful others locus of control beliefs used more emotion-focused coping. However, there was no relationship between powerful others locus of control beliefs and emotion-focused coping for women in the experimentally induced victim group. For experimentally induced victims, both men and women with high chance locus of control beliefs used more emotion-focused coping. In both groups, importance of outcome did not moderate the locus of control and coping relation. Implications of these results and suggestions for future research are discussed.
