The purpose of this study was to measure the possible relationship between Advanced Placement and dual enrollment courses for economically disadvantaged students on 2-year completion rates at public Tennessee higher education institutions. A quantitative, quasi experimental, comparative design was used to analyze secondary data to determine if there is a relationship between Advanced Placement, dual enrollment courses, and 2-year completion rates for students in Tennessee community colleges and public universities. The sample for this study consisted of students who entered a Tennessee community college or Tennessee public university in the Fall of 2015. These students had taken at least one Advanced Placement or dual enrollment course in a Tennessee high school. In addition, the sample for this study was economically disadvantaged using the Tennessee method for direct certification when taking an Advanced Placement or dual enrollment course. The researcher observed that economically disadvantaged students are significantly less likely to attain completion in two years as compared to noneconomically disadvantaged students. The researcher also observed that economically disadvantaged students who receive credit in an AP math or English class are significantly more likely than economically disadvantaged students who did not receive credit in an AP math or English class to complete a degree in two years. The researcher also observed that economically disadvantaged students who participated in a dual enrollment course are significantly less likely to attain completion in two years than noneconomically disadvantaged students, however if economically disadvantaged students receive credit in a dual enrollment course they are significantly more likely to complete a degree in two years.

At an urban school district, administrators were concerned about the English language arts (ELA) achievement gap between economically disadvantaged (ED) students and non-economically disadvantaged (NED). To address this gap in performance, district administrators instituted an extended day program (EDP) for ED students that included additional learning time and individualized strategies in ELA. The purpose of the study was to determine the extent of the impact that the EDP had on ED students in ELA achievement. The quasi-experimental quantitative design was guided by Carroll's model of school learning and explored the difference in ELA Partnership for Assessment of Readiness for College and Careers (PARCC) scale scores between ED students who participated in the EDP and ED students who did not during the 2016/2017 school year. The study examined 28 matched-pairs of students, based on grade level and reading ability who were classified as ED during school year 2016/2017, following an intervention. Ex post facto analysis included a paired-samples t test to determine whether a statistically significant difference existed in ELA PARCC scores for ED students who received the intervention and those who did not, controlling for grade level and reading level. Data analysis indicated no statistical difference between groups. The project deliverable recommended implementation of a Response to Intervention program to replace the EDP because such a program would affect more students. Local school administrators may use the findings of the study to effectuate positive social change by making program decisions that could support the improvement of ELA achievement of ED students. In the larger context, this study could become part of the body of literature on the relationship between extended learning time and academic achievement among ED students.

The collective body of U.S. legislation, colloquially known as the Farm Bill, authorizes a suite of practices and programs under its Conservation Title. This includes the Conservation Reserve Program (CRP), which incentivizes agricultural producers to remove arable land from production to enhance soil retention, improve water quality, and restore wildlife habitat. Conservation Practice 33: Habitat Buffers for Upland Birds (CP-33) was the first CRP practice to target wildlife habitat restoration. CP-33 incentivizes producers to reestablish native herbaceous vegetation along crop field margins. Producers are often concerned with the economic opportunity costs of CP-33 enrollment. I used yield data derived from 44 agricultural fields in the Mississippi Alluvial Valley, USA to compare the environmental and economic opportunities associated with CP-33 establishment. I used yield data to develop a revenue distribution function to illustrate CP-33 revenue as commodity prices fluctuate. I found that as commodity prices increase, CP-33 implementation becomes less profitable.

The purpose of this study was to identify which school divisions in the Commonwealth of Virginia have equitable representation of Culturally Linguistically Economically Diverse (CLED) students in gifted programs within their schools. Existing literature on CLED students was reviewed. Three years of data (school years 2016-2017, 2017-2018, and 2018-2019) obtained from the Virginia Department of Education (VDOE) were analyzed to determine whether equitable representation exists within gifted education programs in each of the 132 Virginia school divisions. Furthermore, the researcher used the Freedom of Information Act (FOIA) to acquire longitudinal gifted data from each school division 2016-2019. The Relative Difference Composition Index (RDCI), Equity Allowance Formula (EAF), and Representation Index (RI) formulas were used to determine, which schools have equitable representation within their gifted programs. This study sought to answer the following questions: 1. What school divisions have proportional representation of economically disadvantaged students? 2. What school divisions have proportional representation of Black or African American students? 3. What school divisions have a proportional representation of Hispanic or Latinx students? At the conclusion of the data collection process, the researcher examined (1) which school divisions have equitable representation of gifted students in their gifted programs in schools using the EAF, and (2) What schools have equitable representation utilizing the RI. The analysis revealed the majority of the school divisions in the Commonwealth of Virginia had equitable representation when the EAF was applied to the economically disadvantaged students. When the EAF was applied to the 2016-2019 school years data for the Black or African American students and Hispanic or Latinx students the range of 33%- 42% were proportionately represented. The English Language Learner students were not proportionately represented when the EAF was applied. When the RI formula was applied to the data, none of the school divisions had perfect proportion in the Commonwealth of Virginia. In 2016-2017, Halifax school division had a score of .86 which translates to proportionate representation when the EAF and RI formula were applied to the data. The findings of this study provide educational leaders with relevant research toward equitable representation for CLED students in the Commonwealth of Virginia. The VDOE and school leaders could offer professional development regarding equitable representation for teachers and staff that work with CLED students to resolve disproportionality. School divisions could benefit from the implementation of equity allowance goals to help reduce inequitable representation of CLED gifted students. / Doctor of Education / The underrepresentation of students with low incomes in gifted education is a persistent problem (Ford, 2013a; Hamilton, McCoach, Tutwiler, Siegle, Gubbins, Callahan, Brodersen, and Mun, 2018). In recent times, researchers have started to discuss educational access and outcomes for low socioeconomic students (Goings and Ford, 2018). According to VanTassel-Baska and Stambaugh (2018), there is a need to address economically disadvantaged for students who attend public schools in the United States. In particular, there are problems formally identifying economically disadvantaged students for gifted services (VanTassel-Baska and Stambaugh, 2018). Researchers seldom focus on gifted students that live in low-income households. The purpose of this study was to identify which school divisions in the Commonwealth of Virginia have equitable representation of Culturally Linguistically Economically Diverse (CLED) students in gifted programs within their schools. Existing literature on CLED students was reviewed. Three years of data (school years 2016-2017, 2017-2018, and 2018-2019) obtained from the Virginia Department of Education (VDOE) were analyzed to determine whether equitable representation exists within gifted education programs in each of the 132 Virginia school divisions. Furthermore, the researcher used the Freedom of Information Act (FOIA) to acquire longitudinal gifted data from each school division 2016-2019. The RDCI, Ford Equity (EAF), and RI formulas were used to determine, which schools have equitable representation within their gifted programs. At the conclusion of the data collection process, the researcher examined (1) which school divisions have equitable representation of gifted students in their gifted programs in schools using the EAF, and (2) What schools have equitable representation utilizing the RI. The analysis will reveal which school divisions have equitable representation within the Commonwealth of Virginia.

The purpose of this qualitative study was to assess teacher perception of how economically disadvantaged students at White Pine School were being served. The results of this study may help educators at White Pine School determine how to support and improve learning conditions for economically disadvantaged students. Data collection techniques included individual interviews, focus group interviews, and document review. The following conditions were discovered in relation to economically disadvantaged students: positive home-school relationships; desire to become a full-service school; limited parent-training opportunities with limited participation; limited professional development opportunities; limited poverty discussion in professional learning communities; underuse of college partnerships; need for a mentoring program; need for programming to combat absenteeism; demand for additional early intervention programs; positive student-teacher relationships; a variety of opportunities for students of poverty to build confidence; teachers high expectations from teachers; importance given to enrichment opportunities; teaching strategies focused on active learning; assignment of small, meaningful doses of homework; limited tutoring opportunities; and use of multiple data-collection methods. Recommendations for improving how students of poverty are served include continuing to expand efforts concerning positive home-school relationships, investigating the possibility of becoming a full-service school, designing a powerful parent-training program, offering additional professional development training for teachers, developing poverty-related topics for professional learning communities, finding ways to improve partnerships with local colleges and universities, designing a quality mentoring program, finding creative ways to address absenteeism, finding additional means of providing early intervention, continuing to develop positive student-teacher relationships, finding additional ways to build confidence, maintaining high expectations of students of poverty, creating additional meaningful enrichment opportunities, searching for the best teaching strategies to improve learning, continuing to assign meaningful homework with assistance as needed, creating a comprehensive tutoring program, and collecting meaningful and useful data to help teachers increase students' achievement.

A broader research project was undertaken on experiences of care and respect within intergenerational relationships. The current study, which forms part of this project, focused more specifically on adolescents’ motivations for providing care to persons older than 60 years. Care is normally expressed in the interactions between people, and in this instance between generational members. In the African context, care between generational members is important because care is particularly provided in a social and familial context between generations and not necessarily by the government in terms of formal care services. Care, specifically for older persons has become a scarce commodity. In the light of different aspects like the growing older population, poverty, unemployment, and HIV/AIDS certain structural changes in families and between generations have come about. The changes influenced caregiving by delivering a larger number of dependant persons and a lack of capacity to provide care. Adolescents are important in the relationship with older persons, because often the relationship between persons from different generations, who find themselves in a deprived environment, is the only source for the provision of care. The findings of this study can possibly give an indication of how care in relation to older persons are being motivated in order to better plan for the care needs of older persons. The motivation for demonstrating care is particularly important because some motivation types are perceived to encourage more sustainable actions and caregiving than others. Currently intergenerational support and care are in short supply, suggesting the presence of less sustainable types of motivation. Care, in this study, refers to the satisfaction of social goals and psychological needs by means of tangible (instrumental/physical care) and intangible (emotional care) exchanges between intergenerational members. Intergenerational care encompasses upward and downward care. Upward care occurs when care is transferred from a younger generation to older persons, while downward care refers to care provided by older persons to younger people. Previous studies referred mostly to informal caregiving, downward care, or upward care provided by adult children. A limited number of studies exist of upward care provided by adolescents, specifically to persons older than 60, and research on younger people’s motivations for care is also rare. The theoretical framework that informs this study is Self-Determination Theory (SDT). This theory revolves around motivation, known as the force that compels one to act, or to conduct an activity such as care. SDT includes two broad categories of motivation types, namely autonomous and controlled motivations. The autonomous (self-determined) motivation category includes intrinsic motivation (i.e. conduct that stems from the inherently satisfying experience a particular activity offers), along with two well-internalized extrinsic motivation subtypes (namely identification and integrated regulation). Controlled motivation includes two more controlled and less internalized motivation subtypes (namely external and introjected regulation). Extrinsic motivation is when an activity is performed for a separate and external outcome. The different types of motivation consequently incorporate differing levels of self-determination to conduct certain activities. The more autonomous (self-determined) the motivation, the more sustainable actions of care. Adolescents are capable in terms of ego and cognitive development to be more self-determined and intrinsically motivated. Even though they may have the capacity to be more self-determined motivated, this is not always the case. Persons at this stage of psychosocial development according to Erikson’s lifespan approach focus more on peer relationships, and tend to conform to community expectations and social group norms. In such cases adolescents may experience motivations that include less self-determined motivation types, because they are controlled by external expectations and norms. Unfortunately less self-determined motivation types may also produce less sustainable care actions. A qualitative research method was applied to describe adolescents’ experiences of care in relation to older persons. In the findings, motivation for care was a major theme and it was therefore decided to focus only on this aspect in this study. The participants included 15 Setswana-speaking adolescents (seven boys and eight girls) between the ages of 12 and 16, who were selected by means of a nonprobability convenience sampling method. Data were collected in an economically vulnerable community where the participants lived, Vaalharts agricultural valley in the Northern Cape Province of South Africa. This community is considered economically vulnerable because the majority of its members receive only irregular income and have to rely on meagre government grants to support multi-generational households. 15 Participants were included in the research; eight individuals participated in the Mmogo-method®, a projective visual data-gathering method, and all 15 participants completed self-reflective journal entries to supplement the data. During the Mmogo-method® session, participants were asked to build something that would show how they experienced care in relation to a person older than 60, using a lump of clay, grass stalks and beads. The self-reflective research journals included semi-structured questions to guide the participants. Descriptive phenomenological psychological, thematic, and visual analysis was employed to analyse the collected data. Credibility, dependability, transferability and conformability were applied to ensure the trustworthiness of the study. Moreover, ethical research conduct was ensured by applying the guidelines provided by the Department of Health for responsible and ethical research conduct in South Africa as well as the framework provided in Chapter 9 of the National Health Act 61 of 2003. Firstly a perceived absence of older persons in caring relationships emerged from the findings. The findings further revealed that the younger generation was moved by external stimuli such as observing struggling older persons or by obeying older persons’ explicit requests for help, to provide physical/instrumental care to older persons. In response to external stimuli adolescents were extrinsically motivated to care which was observed in obedience and perspective taking. The participants were also extrinsically motivated by feelings of obligation; to ensure older persons‟ happiness; from their submissive position in relation to older persons; and for returning care that were bestowed on them by the older persons. However, although the participants were extrinsically motivated to care, different levels of self-determination and self-choice seemed to be present in their behaviour. These findings provide a broader awareness with regard to adolescents’ motivations for care provision. The knowledge gained from this project could serve to inform intergenerational programmes designed to facilitate feelings of autonomy and emphasize gratitude as a motivator in intergenerational and interpersonal environments. / MA (Research Psychology), North-West University, Potchefstroom Campus, 2015

South Africa is on a path of dramatically increasing its energy supplying capabilties. Eskom (the main utility supplying electricity to the national grid) recently announced that future power station technologies will focus on renewable energy and nuclear power. This is done in an effort to reduce South Africa’s dependance on burning fossil-fuels and thereby decreasing CO2 emissions and other harmful gases. This, together with the fact that there are a lot of fresh water scarce areas especially along the Eastern Cape coast of South Africa, is what inspired this study. This study investigates the use of a 200 MWth High Temperature Reactor (HTR) for cogeneration purposes. Heat from the reactor is utilised for electricity generation (Rankine cycle) and process heat (desalination). Two desalination concepts were evaluated thermodynamically and economically, namely Multi-Effect Distillation (MED) and Reverse Osmosis (RO). Computer software, Engineering Equation Solver (EES), was used to simulate different cycle configurations, where the heat available in the condenser was increased successively. The coupling of the two desalination technologies with a HTR was compared and it was found that a RO plant produces nearly twice as much water while sending the same amount of electricity to the grid (compared to coupling with MED). Coupling options were investigated and each simulation model was optimised to deliver maximum output (power and water). The best configuration was found to be the coupling of a HTR with a RO plant producing 86.56 MW generator power. This is equal to 2077 MWh/day. Using 332 MWh/day for desalination through RO, delivers 73 833 m3/day fresh water and results in 1745 MWh/day sent to the grid. This scenario is the best option from a thermodynamic and economic point of view. From an investment point of view, it will produce an Internal Rate of Return (IRR) of 10.9 percent and the Net Present Value (NPV) is calculated to be R 2,486,958,689. The results and analysis for the different cycle configurations are presented in such a way that an easy comparison can be made. / Thesis (M.Ing.

Public procurement in the Czech Republic is a complex process directly settled by the legal procurement framework which defines various contract-awarding procedures. This study focuses on the part of selection process when procurers can decide between using lowest price criterion or most economically advantageous tender (MEAT). We found an evidence of preference of lowest price criterion, especially in the recent years. The main goal of the study is therefore to provide a comprehensive analysis of the leading drivers of selection of specific criteria and their consequential effects. Taking into account various characteristics of public procurement processes, we found out that in general lowest price criterion is preferred by public contracting authorities and by procurers with larger number of employees. This type of selection process also consequently provides an interesting trade-off between higher competition in terms of number of bidders, higher stability in terms of less interventions by the Office for the Protection of Competition (OPC) but also higher probability of consequent extraworks.
