Show moreThis study investigated the relationships, if any, between the number, nature, and organization of partnerships between academic and student affairs and measures of institutional success and student learning. Specifically, this research sought to: (a) investigate the relationships between the number, nature, and organization of partnerships with institutional retention rates, graduation rates, and students' engagement in educationally purposeful activities, (b) test the feasibility of a classification system for the organization of partnerships developed by O'Halloran (2005), and (c) explore the alignment between reported goals for engaging in collaboration and the actual nature of existing partnerships. The population for the study consisted of 93 Senior Student Affairs Officers (SSAOs) at doctoral-granting institutions who participated in the spring, 2005 administration of the National Survey of Student Engagement (NSSE). The survey instrument was adapted from O'Halloran (2005) and was administered in spring 2006. Of the 93 surveys administered, 52 were completed for a response rate of 55%. The findings indicated that the nature of the partnerships has significant effects on measures of institutional success and student learning. Furthermore, 75% of the respondents reported that their institutions had developed partnerships for the purpose of enhancing academic performance or increasing student retention and/or persistence. Implications of these findings are discussed in terms of the iterative relationships between the number/nature of partnerships, goals of partnerships, and outcomes of partnerships mediated by organizational structures and institutional characteristics.

Abstract / Description

Marine turtle reproductive success is strongly correlated with the stability and quality of the nesting environment. Because females show fidelity to key nesting beaches, the management and physical characteristics of these beaches directly affect future generations of marine turtles and may be essential for the recovery of these threatened and endangered species. The impacts of beach restoration on loggerhead turtles (Caretta caretta) and on green turtles (Chelonia mydas) were investigated....
Show moreMarine turtle reproductive success is strongly correlated with the stability and quality of the nesting environment. Because females show fidelity to key nesting beaches, the management and physical characteristics of these beaches directly affect future generations of marine turtles and may be essential for the recovery of these threatened and endangered species. The impacts of beach restoration on loggerhead turtles (Caretta caretta) and on green turtles (Chelonia mydas) were investigated. Previous studies concerning beach nourishment projects have focused on loggerhead turtles. I compared data between nourished and non-nourished areas and between loggerhead and green turtles. I found, at one season post-nourishment, negative effects on nesting success and no significant effect on reproductive success for both loggerheads and established the same relationships with green turtles. Physical attributes of the fill sand, which did not facilitate acute scarp formation or severe compaction, did not physically impede turtles in their attempts to nest. Instead, the decrease in nesting success was attributed to an absence of abiotic and or biotic factors that cue nesting behavior. The increase in loggerhead nesting success rates during the second season post-nourishment was attributed to the equilibration process of the seaward crest of the berm. After the beach was restored, both species of turtles placed nests significantly farther from the water in the nourished area than in the non-nourished area. Green turtles nested on or near the dune and loggerheads nested on the seaward crest of the berm. The tendency of loggerheads to nest closer to the water resulted in more loggerhead than green turtle nests being "washed out" by erosion during the equilibration process. There was a significant increase in hatching success only for loggerheads when wash outs were excluded, thus illustrating the importance of nest placement and the detrimental effects of the equilibration process to the reproductive success of loggerheads. A decrease in reproductive output occurred during the first season post-nourishment. The reduction in the estimated total number of hatchlings produced (reproductive output) was a consequence of decreased nesting success lowering nest numbers. This reduction demonstrates that, regardless of similar reproductive success rates, marine turtles incurred net losses during the first season following nourishment. These results further reveal the impacts of decreased nesting success and the importance of minimizing excessive non-nesting emergences associated with beach nourishment.

Show moreProfit, ergonomics, safety, employee morale, quality, efficiency, and productivity are critical components that greatly impact company success within manufacturing organizations. Therefore, it is essential that a valid and reliable systematic approach that encompasses all of these factors be developed for use by top management in today's rapidly changing manufacturing environment. Organizational-level decisions made based upon a single goal or narrow perspective that only considers one of the aforementioned components, such as profit, while ignoring others, such as employee morale, have proven harmful to the long term viability and success of manufacturing companies. Often organizational leaders are not adequately equipped to consider multiple factors that are pertinent to company success due to the complexity associated with considering a large number of organizational variables and the lack of quantitative tools and techniques to assist in this process. Thus, valid, reliable and readily available tools, methods, and techniques for integrating into decision making multiple components of profit, ergonomics, safety, employee morale, quality, efficiency, and productivity are highly needed in today's complex manufacturing business environment. This research responds to the need to develop quantitative models by creating a company success index. This index was developed using an approach to analyze and evaluate multiple factors at the strategic, tactical, and operational levels of an organization that are essential to achieve company success in manufacturing enterprises. The resulting company success index model was validated using information on market share (Specificity = 0%, Sensitivity & Accuracy = 87.5%). Future research related to this topic area should include additional studies to expand upon model validation and verification techniques.

Show moreThe decision tree is a well-known methodology for classification and regression. In this dissertation, we focus on the minimization of the misclassification rate for decision tree classifiers. We derive the necessary equations that provide the optimal tree prediction, the estimated risk of the tree's prediction, and the reliability of the tree's risk estimation. We carry out an extensive analysis of the application of Lidstone's law of succession for the estimation of the class probabilities. In contrast to existing research, we not only compute the expected values of the risks but also calculate the corresponding reliability of the risk (measured by standard deviations). We also provide an explicit expression of the k-norm estimation for the tree's misclassification rate that combines both the expected value and the reliability. Furthermore, our proposed and proven theorem on k-norm estimation suggests an efficient pruning algorithm that has a clear theoretical interpretation, is easily implemented, and does not require a validation set. Our experiments show that our proposed pruning algorithm produces accurate trees quickly that compares very favorably with two other well-known pruning algorithms, CCP of CART and EBP of C4.5. Finally, our work provides a deeper understanding of decision trees.

Show moreVertebrate males frequently carry higher numbers of parasites than females. This bias in parasite loads could be a consequence of sexual selection. Grouping species are also assumed to be afflicted with larger numbers of parasites than solitary animals and associated costs of this parasitism could vary with group size or structure. I examined sex-biased parasitism and the influence of group size on parasite loads in Cape ground squirrels (Xerus inauris), a highly social species that occurs in the arid regions of southern Africa. Males carried three times as many ectoparasites as females, but females harbored nearly three times more endoparasites than males. Amount of time spent (per hour) autogrooming was similar between males and females, but amount time spent allogrooming by adult female was over eleven times that of adult males. Longer allogrooming of group members could be decreasing the numbers of ectoparasites of group members and ultimately the group. Males infrequently give or receive allogrooming and travel in very large home ranges, potentially increasing their exposure to ectoparasites. However, movement throughout a large home range may result in males foraging in areas with lower densities of fecal pellets, which could explain the lower endoparasite loads observed in males. When I considered the age class of group members, female age classes were similarly parasitized but male age classes were not. Sub-adult males carried similar ectoparasite loads to adult males and similar endoparasite loads to adult females. This result is of particular interest because sub-adult males are becoming scrotal but typically remain in the group until adulthood. Sexual selection does appear to influence parasite loads in this species, and parasite removal or avoidance potentially mitigates individual parasite loads and their associated costs. Parasites can be detrimental to the health, longevity, and reproduction of their hosts, but these costs are rarely quantified. I removed ectoparasites and endoparasites from Cape ground squirrels for three months and evaluated changes in female body mass, reproduction, burrow use, and grooming in response to parasite removal. Female body mass did not increase with parasite removal, but reproductive success (per capita offspring raised to emergence) increased nearly four-fold, while allogrooming by treated females decreased. Since breeding is highest in the late winter dry season when fewer resources are available, the impact of parasites may be highest during this season. Lactation and gestation are the most physiological stressful processes that females undergo, and the dramatic increase in reproductive success in treated females suggests that these females are able to allocate more resources to reproduction than females afflicted with parasites. These results suggest that studies investigating reproduction and fecundity must consider the vulnerability of the host to parasite infection and the potential impact on reproductive success.

Show moreWhat Instructional Modification Implementations Bring Adult Education Learners to Success and Retention? Analysis of an Online Adult Basic Education Program. Adult learners enrolled in my online Adult Basic Education program showed low completion rates for the course. This study's purpose was to discover what instructional modifications would bring these learners to a successful outcome in the program. I implemented the following instructional modifications: asynchronous email communication, weekly progress reports emailed to each participant and a minimum requirement of 10 assignment completions on a weekly basis. Teacher-student interaction increased because of these implementations. I reviewed literature that discussed distance education, adult learners and teacher-student interaction to discover strategies that would improve student achievement in an online course. After reviewing the literature, I determined that there were three missing elements in my program: structured communication between the teacher and student (Palloff & Pratt, 1999), standards for online coursework completion (Comings et al., 1999) and a system to inform students of their progress in the program (Comings et al., 1999). I found that teacher-student asynchronous communication, a weekly requirement of 10 completed lessons and weekly progress reports of student accomplishments encouraged students to complete coursework on a regular basis. Students were conscientious, taking more responsibility for their learning. Students had a higher rate of coursework completions during the research study period, with performance increasing 73%.

Show moreThere is a certain tradition, pageantry, rivalry, and glory in college football. It is well known that college football can be a big time money maker and sometimes covers the costs of other athletic teams within a school. However, it is also recognized that many college football programs lose money or struggle to break even. Thus, there is tremendous variability that exists in the amount of resources a school may have and the outcomes in athletic success, while there is not always a one to one correspondence between the two. The purpose of this study is to examine and analyze the quantifiable determinants of success, considering both financial and non-financial variables. The pressure to win, and do so immediately; brand; and outdo other schools in the facility "arm's race" has reached unprecedented levels.

Show moreSince 1970, high project failure rate and low user satisfaction has elicited research on users and their role in the process. It is believed that users' physical participation or psychological involvement in the development process can improve user satisfaction and/or system quality. Previous research treats users as a source of requirements and hypothesizes satisfaction to increase when requirements are fulfilled. However, inconsistent conclusions lead to confusion. Recently, a co-production concept has been proposed to understand consumer participation in product development process. In this reconceptualization, users, instead of requirement generator, should be part of the production. In this study, based on co-production concept, we view users as one knowledge source and study how knowledge can be coordinated through the co-production process. After collecting data from 97 system users, most of the hypothesized relationships have been confirmed. IS-user co-production has a positive effect on expertise coordination and, in turn, improves teamwork outcomes. The only relationship that is not significant is between "bring expertise to bear" and "creativity." Implications for practitioner and suggestion for future research are provided. Co-production was found to be a second-order construct comprised of multiple formative constructs. Higher levels of coproduction behavior were expected and were found to produce better outcomes of collaborative efforts. For future study, this relationship is expected to hold true when pairs of information systems developers and information systems users who have worked together on the same information systems development project are surveyed at the end of their projects (or just before it ends or recently thereafter).

Show moreABSTRACT Six Sigma is a business improvement strategy that aims to improve process performance using a structured methodology that identifies and removes the causes of defects in manufacturing and business processes, while implementing the lean concepts attempts to remove wasteful activities from those processes. In practice, the Six Sigma strategy and the Lean philosophy are combined and often viewed as one integrated philosophy, where the philosophy of Lean Six Sigma simultaneously removes wasteful activities from a process and reduces the variability of that process. This thesis research reviews the concepts and implementation of Lean thinking, Six Sigma strategy, and the integrated concept of Lean Six Sigma, with emphasis in service organizations. Most importantly, this thesis summarizes the critical success factors for implementing Lean Six Sigma within a service business environment and categorizes them within a proposed multi-level taxonomy that can be used by service business units and service providers to improve the success of Lean Six Sigma implementation.

Show moreCoastal habitats are highly dynamic and vulnerable to landscape-level disturbances such as storms and restoration projects. Along the east coast of Florida these areas are particularly valuable as they provide significant nesting habitat for two sea turtle species, the threatened loggerhead (Caretta caretta) and the endangered green turtle (Chelonia mydas). This coast was heavily impacted by three major hurricanes in 2004 and in some areas by large restoration projects in 2005. Recent remote sensing methods allow for broad evaluation of the shoreline and thus the ability to assess sea turtle nesting habitat at a landscape scale. I collected nesting data for southern Brevard County, Florida from 1989 ÃÂ 2005 and for Canaveral National Seashore, Florida from 1995 ÃÂ 2005. I used LiDAR (Light Detection and Ranging) and IfSAR (Interferometric Synthetic Aperture Radar) remote sensing to map sea turtle nesting habitat in both areas following the 2004 hurricanes and any subsequent restoration. Canaveral National Seashore underwent no restoration while southern Brevard County received extensive restoration. Topographic variables (e.g., total sand volume, width, and slope) derived from the remote sensing data were compared across three time periods (pre-hurricane, post-hurricane, and recovery period) and I compared nesting success data from 2004 to 2005. I built regression models for 2004 and 2005 to determine which topographic features influenced loggerhead and green turtle nesting the most. Green turtle nesting success declined from 2004 to 2005 only in highly restored areas while loggerhead nesting sucess declined throughout. Hurricanes caused a reduction in most of the topographic variables and restoration predominantly impacted aspects of the beach profile (e.g. slope and width). Loggerheads responded to profile characteristics (e.g. upper and lower beach slopes) though green turtles showed no consistent response to topography. The results indicate that both loggerheads and green turtles are sensitive to beach restoration, although loggerhead nesting is more influenced by beach morphology and green turtle nesting may be influenced more by other dune features such as vegetation cover.

Show moreHabitat loss is among the biggest threats to conservation worldwide, so habitat restoration plays an increasing role in endangered species management. This is especially true for species with high site fidelity, such as nesting marine turtles. Sand replenishment is commonly used to restore coastal beaches after severe erosion events, and may affect marine turtles and other species that live or reproduce in that habitat. I investigated how abiotic characteristics of sand used in a dune restoration project at Archie Carr National Wildlife Refuge, Florida, affected reproduction of the federally-endangered green turtle (Chelonia mydas). Sand structure and composition can affect egg development and hatching success by altering nest conditions, with nests in fine-grain or very coarse sand suffering decreased hatching success. I determined that calcium carbonate content (27.0% ñ 1.4 SE vs. 15.1% ñ 3.8 SE), moisture content (3.29% ñ 0.26 SE vs. 4.59% ñ 0.25 SE), and grain size (427.53 μm ñ 14.1 SE vs. 274.66 μm ÃÂÃÂÃÂñ 29.1 SE) differed significantly between natural and restored dunes. Hatching success of green turtles (44.7% ÃÂÃÂÃÂñ 6.2 SE vs. 65.8% ñ 5.3 SE) was significantly lower on restored dunes compared to natural dunes with an estimated loss of 22,646 hatched eggs. Hatching success also decreased as the nesting season progressed. These results demonstrate the importance of regulating fill material used in beach restoration projects; substrate characteristics are easily evaluated and can significantly influence marine turtle hatching success.

Show moreMigratory connectivity between breeding and foraging areas is a vital component of the ecology of a diverse collection of marine vertebrates. Habitat quality, composition, and resource availability at these locations have direct ramifications for individual fitness. The green turtle (Chelonia mydas) is a long-lived, highly migratory species of conservation concern. Important green turtle nesting habitat in Florida is protected, but more information is needed to identify foraging habitats and the influence these habitats have on reproduction. Here, I used stable isotope analysis of ?13C, ?15N, and ?34S and satellite telemetry validation to determine the number of putative foraging areas used by the breeding aggregation at the Archie Carr National Wildlife Refuge (ACNWR), and the relative contribution of each foraging area. I evaluated the influence of foraging area and other variables on egg size, clutch size, hatching success, and emerging success using model selection frameworks. Isotopic values of skin and eggs were used to build conversion equations between the two tissue types. Results suggest strong migratory connectivity between the ACNWR and the Florida Keys/Florida Bay complex. I found that the influences of foraging area are likely to be more detectable when evaluating female-centric fitness metrics like clutch size and egg size; these influences are more muted in hatching and emerging success, which are strongly influenced by nest incubation conditions. These are the first green turtle-specific tissue conversion equations for ?13C and ?15N, and the first ?34S equation for any marine turtle species. These will allow researchers to have a (")common currency(") between frequently collected samples to better compare results.

Show moreThis thesis examines the determinants of presidential success with Congress. Seven essential sources of presidential power in the current era of party polarization were derived from the extant literature, and these factors were delineated into the institutional (formal) and non-institutional (informal) policymaking tools of the presidency. Variables that explain presidential legislative success include: intraparty support in Congress, the use of veto bargaining, executive orders and signing statements (institutional factors); as well as public approval, 'going public,' and strategic lobbying of Congress (non-institutional factors). Case studies of the presidencies of Bill Clinton and George W. Bush analyze the role of these policymaking tools in four key legislative battles of each presidency. Regression models were constructed to test the effect of these variables on presidential legislative success. The case studies elucidate the relationship between non-institutional factors and their subsequent impact on key presidential policy priorities, particularly the interaction between public approval and going public. Findings indicate a positive relationship between a president's strategic bargaining ability with Congress and subsequent legislative success. Findings also show no significant relationship between intraparty support and presidential success when focusing on only key legislative battles between the executive and legislative branches, contrary to the findings of prior research. Future research might examine the various relationships between these policymaking tools and how they affect the nature of presidential power in the current era of heightened party polarization and ideological homogeneity.

Drawing on analytical concepts from CDA and related perspectives, such as multimodal discourse analysis and social semiotics, the paper analyzes the visual and textual elements of a sample of the FWP and TWS memes. The paper argues that the text and images featured in the memes are ideologically salient and discursively construct oppositional binaries between (")us(") and (")them(") in terms of wealth disparity.

Show moreThe purpose of this study was to synthesize the counter-narratives of mathematically successful African American students. The gap in educational achievement between African American and White students is well documented in the United States, especially in mathematics education. Although Florida Comprehensive Assessment Test scores have increased for both groups at Seminole High School, the gap has remained over 30% for nearly a decade. Most research on this topic has focused on the reasons why African American students fail to achieve. Various individual, social, and organizational factors have been suggested. However, a growing body of research has highlighted the stories of mathematically successful African American students.Using best evidence review methods, an exhaustive review of the literature identified 22 research articles published between 2004 and 2013. All studies collected interview data with mathematically successful African American middle school, high school, and higher education students in the United States. Meta-synthesis was used to synthesize findings across studies. Among the 151 participants across 22 studies, six common experiences were identified as contributing to students' mathematical success: supportive teachers, supportive family, supportive peers, a strong mathematics identity, ability to deal with racial stereotype, and supportive organizations. Most importantly, this meta-synthesis highlights the tendency of prior research to focus on de-contextualized factors rather than understanding students holistically within their broader social and community environment. Insights from this study lead to several recommendations for improving mathematics education for African American students at Seminole High School and for suggested future research on this topic.

Show moreFlorida Virtual School (FLVS) was established in 1997 as an online education alternative for the residents of Florida. The purpose of this study was to identify policy changes at the organizational, state, and federal levels that had the propensity to impact student success (as measured by student's final letter grade) at FLVS. In addition, this study identified which type of institutional isomporphic policy (coercive, mimetic, or normative) best classified major policy changes in the organization from 1997-2007. The use of institutional theory as the guiding framework for this study proved to be beneficial and enabled the researcher to conclude which types of policy are the most effective in increasing student success in the secondary online education environment. This study utilized ANOVA and regression analysis to detect whether or not changes in policy at the organizational and federal level have a statistically significant impact on student success in the secondary online education environment. This study reveals that student success at FLVS is consistently decreasing and that the change is statistically significant. Regression analysis found that the policy changes at FLVS in this study explain some of the variance detected in the change in the mean, or GPA, of the school. This study found that both coercive and mimetic policies have a statistically significant impact on student success in the secondary online education environment as identified in the isomorphic mechanisms outlined in institutional theory. This study is important to the field of literature regarding secondary online education in that it opens the discussion regarding types of policy and the potential impact that policy changes have on student success in the secondary online education environment. In addition, this study serves as a framework upon which future studies can be conducted and are recommended in this study.

Show moreNon-traditional students make up approximately 20% of the undergraduate student population nationwide and are one of few segments of the student population that are not provided with targeted programs and services. To help this cohort achieve their goals whilst universities can increase their retention rates, this research begins a review of the non-traditional student literature to gain an understanding of what this population faces as far as barriers to their education. The literature also provides recommendations and further information in retention efforts to support the student during their academic years. Next, an analysis of non-traditional student support services at 4-year public universities was conducted between 15 different institutions, including the University of Central Florida. Only two of the universities in this study had a department or office specifically to support the needs of this cohort, one being the smallest universities in this research study and the other was one of the largest. Three more universities researched have a program dedicated to these students. The remaining 10 universities had little to no non-traditional student support structures in place at their university. This research provides 34 different methods for providing non-traditional student support to universities across the nation.

Show moreThe success of Toyota, the inventor of Lean Systems has drawn the attention of academics, researchers, and executives in the last decades. However, existing lean research is largely focused on developed economies in Europe, the Americas, and in Southeast Asia with little focus on the Arab world in general and Qatar specifically. There has been an emergence of manufacturing organizations and Small and Medium- sized Enterprises (SME) in Qatar recently which was the focus of this research. Despite the many attempts to implement lean in organizations, there have been a large number of failed attempts. This research aims to study the Qatari Manufacturing Organizations attempts in implementing lean. The main goal of the thesis is to shed a light on the current state of awareness of lean in Qatari Manufacturing Industry and SME and the potential barriers and challenges that prevent the successful adoption of lean. In order to do so, an online survey was designed through the SurveyMonkey tool and organizations were asked to participate.Numerical and statistical results from the survey are discussed along with Pareto charts and two hypothesis tests. The finding indicates that there is no difference between ISO certified and Non-ISO certified organizations in lean implementation. Further, it is understood that most of the manufacturing organizations in Qatar have some level of awareness of lean concepts/tools and practices. The results also show that organizations are not implementing lean concepts and are not using quality management practices effectively. The main obstacle that manufacturing organizations in Qatar face when implementing lean is (")Lack of Employee Engagement(") and (")Unsupportive Organization Culture("). However, it is noted that the research has some limitations such as having most participating organizations in the survey from specific sectors.

Show moreMuch of the literature regarding Black students at predominantly White institutions (PWI) focuses on these students' academic difficulty, while there is far less attention paid to the performance of higher achieving Black students (Fries-Britt, 1998; Fries-Britt (&) Griffin, 2007). Therefore, this study explored the lived experiences of high-achieving Black female students, focusing particularly on the experiences which contribute to their success at a PWI. The qualitative phenomenological research design was used to highlight emergent themes revealed during the study. Eight purposely selected students participated in one-on-one semi structured interviews and a Sister Circle group process.The participants' stories were highlighted both independently and collectively, reflecting a wide range of sentiments. During the data analysis process, there were six themes that emerged from the data which highlighted the experiences which contributed to the students' success at a PWI. Those themes included: 1) Support, 2) Processing Situations, 3) Defining Success, 4) Involvement, 5) Motivation, and 6) Background. The emergent themes provided strategies and recommendations for Black female students, higher education practitioners, and institutions. These recommendations included areas regarding programming, retention and recruitment strategies, resource creation, and relationship building. Additionally, implications were made for future research initiatives. The data, coupled with the researcher's reflections served as the basis for the implications and recommendations for this study.
