The Relationship Between Registration Time and Major Status and Academic Performance and Retention of First-time-in-college Undergraduate Students at a Four-year, Public University

Smith, Marian Ford 08 1900 (has links)
This quantitative study utilized secondary data from one large four-year, state university in the southwestern US. The relationship between registration time and academic performance was examined as well as the relationship between registration time and retention of first-time-in-college (FTIC) undergraduate students during their first semester of enrollment at the university. The differences between decided and undecided students were tested regarding students’ academic performance and retention of the same population. The study population for the fall 2011 semester included 6,739 freshmen, and the study population for the fall 2012 semester included 4,454 freshmen. Through multiple and logistic regression models, registration time was shown to statistically have a relationship with academic performance and retention (p < .05). Later registrants showed to have a negative relationship with GPA and were less likely to return the following spring semester. The explained variance (R2) for both measures of academic performance and retention along with descriptive statistics are also presented. A Mann Whitney U test and chi square test indicated that a statistically significant association between decided and undecided students exists for academic performance and retention (p < .05). Decided major students performed better as measured by semester GPA performance and were more likely to return the following spring semester. Recommendations and implications are issued regarding future research, policy, and practice.

A pesquisa utilizou informações de variados sites (órgãos federais, associações, entidades de pesquisa, jornais agrícolas de grande circulação), bem como atas de reuniões, relatórios, planilhas e apresentações dos três órgãos federais. Os dados levantados indicaram uma tendência de aumento no tempo de registro de um novo ingrediente ativo. Esta pesquisa reforça a importância de uma discussão profunda sobre a eficiência na gestão pública e incentivo a inovação no Brasil. É possível notar que houve um grande avanço no segmento de produtos equivalentes, importantes para aumentar a oferta e competividade no setor, no entanto, percebe-se que o cenário atual pode não ser atrativo às empresas que focam em inovação devido a falta de previsibilidade no retorno de seus investimentos. / This research analyzes the behavior and performance of MAPA, ANVISA and IBAMA throughout the process of a new pesticide registration in order to evaluate how the regulation application affect the availability of new products to Brazilian farmers. The research based on information from a variety of websites (federal agencies, associations, entities and agricultural journals), as well as meetings minutes, reports, spreadsheets and presentations from the three federal agencies. The data collected indicated a trend to increase the approval timing of a new active ingredient. The data also indicated the importance of a deep discussion about efficiency in public management and incentive to innovation in Brazil. It is possible to notice that there has been a great advance in the segment of equivalent products, important to increase the supply and competitiveness to benefit growers, however, it is noteworthy that the current scenario may not be attractive to the companies that focus on innovation due to the lack of predictability in the return on investment.
