This study aimed to better understand visuomotor tracking and spatial visual imagery. 101 Participants performed four tasks: A Manual Tracking Task (MTT), in which participants mouse-tracked the path of a circle, sometimes with occlusion. A Multi-Object Tracking task (MOT), in which participants tracked several objects simultaneously. The Sussex Cognitive Styles Questionnaire (SCSQ), in which participants self-reported their experience with imagery. A Mental Rotation Task (MRT) in which participants mentally rotate Tetris-like objects. The results demonstrated a significant correlation between the technical/spatial subscale of the SCSQ and the occluded MTT, the MRT, the MOT but not the visible MTT. A multiple regression showed that occluded MTT and the MRT together significantly predicted the spatial/technical subscale of the SCSQ above visible MTT and MOT. These findings support the claim that the cognitive resources behind mental imagery may also be recruited during other tasks that arguably draw on the need for internal visualization.

<p>The quality of software systems depends on early activities in the software development process, of which the management of requirements is one. When requirements are not managed well, a project can fail or become more costly than intended, and the quality of the software developed can decrease. Among the requirements management practices, it is particularly important to quantify and predict requirements volatility, i.e., how much the requirements are likely to change over time. Software measures can help in quantifying and predicting requirements attributes like volatility. However, few measures have yet been defined, due to the fact that the early phases are hard to formalise. Furthermore, very few requirements measures have been validated, which would be needed in order to demonstrate that they are useful. The approach to requirements management in this thesis is quantitative, i.e. to monitor the requirements management activities and requirements volatility through software measurement. In this thesis, a set of 45 requirements management measures is presented. The measures were defined using the goal question metrics framework for the two predefined goals of the requirements management key process area of the capability maturity model for software. A subset of these measures was validated theoretically and empirically in four case studies. Furthermore, an analysis of validated measures in the literature was performed, showing that there is a lack of validated process, project, and requirements measures in software engineering. The studies presented in this thesis show that size measures are good estimators of requirements volatility. The important result is that size is relevant: increasing the size of a requirements document implies that the number of changes to requirements increases as well. Furthermore, subjective estimations of volatility were found to be inaccurate assessors of requirements volatility. These results suggest that practitioners should complement the subjective estimations for assessing volatility with the objective ones. Requirements engineers and project managers will benefit from the research presented in this thesis because the measures defined, proved to be predictors of volatility, can help in understanding how much requirements will change. By deploying the measures, the practitioners would be prepared for possible changes in the schedule and cost of a project, giving them the possibility of creating alternative plans, new cost estimates, and new software development schedules.</p>

This study is an investigation of the correlation between Grade 9 students’ self-theories of their intelligence and their tendency for intellectual engagement. Individuals have been shown to self-identify, with respect to their self-theories of intelligence as either entity theorists (who think of their own intelligence as fixed and fairly unchangeable), or incremental theorists (who think of their intelligence as malleable and able to be increased over time). Previous research has shown that individuals have a strong tendency to self-select one or the other of these theoretical frameworks. This study examined the correlation of this identification with individuals’ tendency to become intellectually engaged in their learning. Other demographic factors were also explored. A moderate correlation between students’ self-theory of their intelligence and their tendency for intellectual engagement was demonstrated. In this study, female students showed a higher proportion of an incremental self-theory of intelligence than males. Implications for educational leadership and classroom planning and instruction were explored

One of the most critical issues facing government over the next decade will be filling management positions vacated by Baby Boomers. The purpose of this quantitative correlational research study was to examine how intrinsic and extrinsic motivations affect job satisfaction among different age cohorts in the public workforce. The public workforce is comprised of Baby Boomers (born 1946- 1964), Generation X (born 1965- 1980) and Generation Y (born1981 to 1996). The theoretical framework for this study was Herzberg's motivation-hygiene theory. A random sample of 213 participants: Generation Y = 40, Generation X = 77, and Baby Boomers = 96, participated in an online SurveyMonkey government panel. The panel was composed of local, state, and federal employees. Participants answered the survey using the Career Goals Scale, the Job Satisfaction Scale, and a brief demographics scale. Data were analyzed using descriptive statistics as a measure of central tendency. Also, inferential statistics using Pearson product-moment correlations, simple linear regressions, and one-way multivariate analysis of variance (MANOVA) were conducted to answer three central research questions. Results revealed that both intrinsic and extrinsic motivations affect job satisfaction. Also, results of the individual one-way ANOVAs did not indicate significant differences in intrinsic motivation or job satisfaction among the age cohorts. Finally, pairwise comparisons determined that there were significant differences in extrinsic motivation between Baby Boomers and Generation Y. The information for this study may inform human resource managers in the public sector, about factors that would affect benefit plan policy, and improve recruitment and retention of employees.

Globalization, 24-hour connectivity, and the expectation that members of the organization commit increasingly more time to work are the reality in an ever-changing environment. Research shows, however, that these demands have resulted in a significant work-life imbalance that produces the opposite effect of reducing productivity. The purpose of this study was to examine the correlation between work life balance satisfaction of front-line managers and the engagement of employees whom they supervise. The variables of these study were: work life balance satisfaction of frontline managers measured by Work life Balance and Emotional Support Scale and engagement perception employees measured by Employee Engagement Survey. Survey data from front-line managers and front-line employees from different industries across the United States were analyzed using a Bivariate Pearson Correlation test to understand the strength of the correlation. The study results r (89) = 0.115, p>.01showed no statistically significant correlation between managers work life balance satisfaction and employee engagement. Work-life imbalances create a significant internal conflict as the manager tries to cope with the stress and pressure that affect his/her overall ability to effectively lead and manage. Their work behaviors can promote or destroy a positive work environment where employees strive to meet the organizations' mission and vision. The organization and front-line managers benefit from understanding the findings because the organization may adopt innovative ways to support manager work-life balance and front-line managers may improve employee engagement. Positive social change is realized in less stress for managers and employees whom interact in an environment that demands more time and flexibility. Considering the amount of time, we spend at work, less stress can improve the overall quality of the work environment and productivity.

As the concern for standardized testing continues to rise, so to does the concern for providing students with an appropriate and equal educational opportunity. The goal of this research was to investigate relevant data to determine if there is a relationship between the wealth behind each student and the academic proficiency amongst 5th grade white, black, and Hispanic students within the 67 counties of Florida. The desired outcome of this study was to produce information relevant to political leaders, educational leaders, and teachers in Florida public school districts with influential strategies necessary to increase the proportion of 5th grade students achieving academic proficiency. The review of literature and analysis of the data gathered from the Florida Department of Education for the school year 2006-2007 and the Florida Department of Revenue, 2007 revealed the following findings: (1) there is a statistically significant correlation between reading scores among white and black students in grade 5 as measured by the FCAT and the wealth behind each student within the state of Florida; (2) there is no statistically significant correlation between reading scores among Hispanic students in grade 5 as measured by the FCAT and the wealth behind each student within the state of Florida. In other words, as school districts are deemed more wealthy, white and black students in grade 5 tend to do better in reading than their white and black counterparts in poorer districts. In contrast, Hispanic students in wealthy school districts do not do better in reading than their Hispanic counterparts in poor districts.

The present study adopted a quantitative method to explore Luxembourgish primary school teachers' practices of Outdoor Education, as well as their knowledge and opinions on this pedagogical concept. Additionally, the influence of diverse environmental and personal factors on the teachers' implementation of Outdoor Education was investigated. In this regard, an online questionnaire with 19 questions related to Outdoor Education was administrated and published. 238 primary school teachers from Luxembourg took part in this online survey and answered questions about Outdoor Education practices, previous experiences in this field, nature relatedness, attitudes towards Outdoor Education, resources to teach outside, willingness as well as self-perceived competence to practice Outdoor Education and possible measures to foster Outdoor Education practices in Luxembourg. Findings revealed that, even though Luxembourgish primary school teachers seem to acknowledge the numerous benefits related to Outdoor Education, their Outdoor Education practices are relatively limited. In Luxembourg, Outdoor Education mostly takes place in schoolyards or nearby forests and is usually oriented towards natural sciences or physical education. Regarding the influence of personal and environmental factors, the teachers' previous experiences in the field of Outdoor Education, their attitude towards this pedagogical method and the available resources to teach outside seem to influence the frequency of Outdoor Education practices. Consequently, teachers with positive attitudes towards Outdoor Education, previous experiences in this field and material and infrastructures suitable for this purpose show tendencies to resort to teaching in an outdoor environment more frequently. The findings from the present study might be of advantage in order to prepare teachers more effectively to teach in outdoor environments and consequently foster the implementation of Outdoor Education in Luxembourg. / /

Physical health can be measured in several ways both based on subjective experiences and with objective tools. However, mental health can only be measured through subjective experiences and sensations, which can be biased. Therefore, researchers adopted the notion of an objective tool to assess well-being as a complement to existing self-reported scales and suggested that heart rate variability (HRV) might be an indicator of well-being. Hence, this thesis investigates the relationship between subjective well-being (SWB) and HRV, particularly high frequency-HRV (HF-HRV). Three hypotheses, which included different forms of well-being, were developed to test the relationship. And the hypotheses were: Cognitive well-being correlates positively with HF-HRV. Positive affect correlates positively with HF-HRV, and negative affect correlates negatively with HF-HRV. A total of 19 healthy Swedish females aged from 20-35 participated and answered questionnaires measuring SWB. After they completed the SWB-scales, their heart rate was measured and then converted into HF-HRV data. The findings revealed no correlations between the cognitive SWB and HF-HRV, neither to affective SWB.
