Due to its unsupervised nature, undergraduate education requires students to manage their own learning. They need to use self-regulated learning (SRL) strategies in order to achieve academic success. However, college students often have insufficient regulatory skills and strategies, suggesting the need for substantive and practical support. Supplemental Instruction (SI) is a well-recognized academic intervention that utilizes peer-led study groups for difficult college courses, through which students can develop their SRL abilities. This study focuses on the role of the SI program in college students’ development of SRL from a person-centered perspective. First, this study examines the heterogeneous effects of the SI intervention on students’ development of SRL by combining latent profile modeling and propensity score matching. Second, it explores the changes in student SRL profiles over the intervention period and determines factors affecting the prediction of such changes using latent transition modeling. Results identify three distinct student profiles: competent regulator, self-confident regulator, and goal-oriented regulator. Within the competent regulator profile, both SI and non-SI attendees’ overall SRL scores significantly decreased over time, though non- SI attendees showed a greater downturn. For the self-confident regulator profile, only SI attendees’ overall SRL scores increased. Both SI and non-SI attendees in the goal-oriented regulator profile had small decreases in scores, which were not statistically significant. Regarding students’ longitudinal transitions between SRL profiles, students in the most desirable profile (competent regulator) remained most stable over time. Students’ SRL in the goal-oriented regulator profile was most malleable in a positive way; approximately 40% of these students moved into the competent regulator profile. In addition, students whose decision to attend the SI sessions was more mastery-oriented tended to fall into more positive transition groups. Furthermore, students whose levels of self-confidence in learning, critical thinking skills, and group work skills increased as a result of their participation in SI sessions were more likely to become members of more positive transition groups. The findings of this study extend previous work by longitudinally examining individual differences in college students’ SRL development. They also provide significant implications for the future design of more targeted interventions.

Many scholars have sought to measure the effectiveness of diverse supplemental instruction programs. Nevertheless, it is difficult to generalize about supplemental instruction or compare data, given methodological and statistical incongruities and diverse approaches and student populations at various institutions. Quantitative and qualitative data suggest that supplemental instruction and embedded tutoring programs facilitate learning and success in all disciplines. We describe best practices for embedded tutoring and supplemental instruction across disciplines and course modalities, evaluate metrics used to assess community college embedded tutoring and supplemental instruction programs, and suggest mixed methods models for assessing these programs.

Embedded tutoring and Supplemental Instruction have the potential to benefit all students, helping to even the playing field in terms of college preparedness and academic skill development

In 2011, home-video distribution company, The Criterion Collection, teamed up with streaming-content provider Hulu, extending their business model to include online streaming to subscribers through Hulu Plus. With the rise of Over-The-Top (OTT) media distribution services into the at-home market, the question that Criterion now faces is: how will the company survive as the market shifts away from Criterion’s established values? And, more pertinently, how does Criterion, by rebranding their image to compete in the streaming market, hope to attract new users without alienating their established fan base or sacrificing their brand identity? This thesis examines the Criterion Collection’s brand identity, business model, and history, focusing on its packaging and promotion, distribution channels (physical and streaming), and the formation of a self-established cinephile community through their website, Criterion.com. In my examination of Criterion’s attempts to branch out into new markets and adapt to alternative modes of media consumption, I argue that Criterion is taking strides to attract new audiences and build a tightly knit online fan community around their brand.

Many families that experience hunger in the United States rely on Food Assistance Programs to meet their daily nutrition needs. However, these programs do not always meet the needs of these individuals, as has been the case for individuals living under higher than expected levels of poverty in the Great Lakes region of the United States. Using policy feedback theory (PFT), the purpose of this case study was to explore the experiences of individuals from a county in the Great Lakes region of the United States, who depend on the federal Food Assistance Program, with particular attention given to evaluate the effectiveness of distribution mechanisms in helping these individuals meet their food needs. Data were collected through interviews with 11 program clients, 3 program administrators, as well as publicly available agency data. These data were inductively coded and then analyzed using Braun and Clarke's thematic analysis procedure. Key findings revealed that clients perceived the Food Assistance Program as ineffective in preventing food insecurity without additional programs and resources. The findings also revealed that distribution mechanisms negatively impacted food recipients with limited income, resulting in increased food shortages, requiring recipients to seek additional food programs and resources. These findings also exposed barriers to employment opportunities for recipients, adding to the stress and anxiety experienced from food shortages. Positive social change implications from the findings include providing information to program administrators that can be used to improve the Food Assistance Program, which may in turn improve the lives of those who rely on food assistance programs.

Title I federal regulations provide funding to school districts to support Supplemental Educational Service (SES) tutoring services to qualified economically disadvantaged K-12 students and that these services should be monitored by school districts to determine its effectiveness. However, a school district in Southern California that is the focus of this convergent parallel design study has not provided sufficient oversight of the SES tutoring program resulting in ambiguity about policy implementation effectiveness. Using a theoretical framework of policy implementation as the foundation, the purpose of this study was to explore the role that quality of service played when administrators implemented the No Child Left Behind Act to evaluate tutoring services supplied by SES providers. Data were collected through a series of interviews with 10 school district administrators who also completed the EDUSERV survey. Data from the interviews were inductively coded and subjected to thematic analysis and descriptive information from the survey were calculated. Findings indicate that SES providers work diligently to support student learning improvement, but the inconsistent oversight by the school district has resulted in disparity in performance scores in educational attainment. The positive social change implications of this study include recommendations to school district leadership to engage in consistent training for leadership in oversight of the SES program as well as improvements in oversight of SES performance in order to enhance outcomes for economically marginalized students

Understanding the ways in which animals utilize space and obtain food are central themes in modern ecology. Formulating broad principles and elucidating the factors explaining such patterns are limited, however, by the availability of data from a broad range of species and systems. This problem especially true of snakes, a predator group about which even the most basic natural history data are often entirely lacking, even among abundant, widespread, and ecologically-important species. I studied the natural history and ecosystem role of one such species, the fer-de-lance (Bothrops asper) in lowland rainforest in Costa Rica. B. asper is a large, cryptic pitviper that is highly abundant in many Central American ecosystems and is strongly relevant to human health due to high incidence of snakebite, yet its biology under natural conditions is almost entirely undocumented. I used radiotelemetry to quantify home range, movement patterns, habitat usage, and foraging behavior. B. asper was found to have smaller home ranges and reduced movement patterns than similarly-sized temperate pitvipers, likely due to a greater reliance upon ambush foraging in patches of high prey density. Snakes also demonstrated strong selection for swamp habitat, which may reflect efforts to exploit frogs as a primary food source due to low availability of small mammals at the study site. I subsequently addressed the trophic status of this B. asper population using a supplemental-feeding experiment. In comparison to control snakes, individuals receiving supplemental food had smaller home ranges, shorter and less frequent movements, increased mass acquisition, and shifted to primarily forest rather than swamp habitat. These results support the suggestion that B. asper at the study site are strongly food-limited. Finally, I tested the hypothesis that fer-de-lance mediate local seed-predation rates by influencing habitat usage and foraging behavior of rodents. A series of behavioral experiments conflicted with many existing studies in failing to support this idea, as three rodent species demonstrated little snake avoidance, and none of likely ecological relevance. Collectively, this dissertation represents the first comprehensive field study of Bothrops asper and is among the first for any tropical snake, and suggests several avenues for future research.

A new damping technology, the Viscoelastic Coupling Damper (VCD), has been developed at the University of Toronto for reinforced concrete (RC) coupled wall high-rise buildings. These dampers are introduced in place of coupling beams to provide distributed supplemental damping in all lateral modes of vibration. This thesis presents an analytical investigation of the application of VCDs in a high-rise case study building located in a region of high seismicity. A parametric study has been conducted to determine the optimal number and placement of the dampers to achieve enhanced seismic performance without compromising the wind response of the structure. Nonlinear time history analyses have been carried out in order to compare the seismic performance of a conventional coupled wall building to alternative designs incorporating VCDs. Results highlight the improved performance of VCDs over RC coupling beams at all levels of seismic hazard. A design procedure for seismic-critical buildings is proposed.
