- Abstract
With the goal of increasing students' academic readiness for college, high schools in the United States are increasingly offering "credit-based transition programs," including International Baccalaureate (IB), Advanced Placement (AP), and dual enrollment. Existing research points to the promise of IB, AP, and other credit-based transition programs for improving students' academic readiness for college; however, conclusions about program effects are often limited by potential issues of selection bias. Despite strong statistical controls and assumptions to address selection, observational research may not be able to determine whether differences in outcomes are caused by program participation or are simply an artifact of the unmeasured characteristics of schools, students, and families that correlate with the decision to participate in these optional programs. To address this knowledge gap and inform future studies of the impacts of IB and other credit-based transition programs, this paper makes three contributions: (1) A review of existing literature is used to produce an empirically-based conceptual model of selection into IB; (2) The conceptual model is used to identify the characteristics of students and schools that participate in the IB Diploma Programme using data from the National Center for Education Statistics and the Florida Education Data Warehouse. The conceptual model also allows researchers to identify key predictors for which there are no data available; and (3) A test of the ability of the available data to adjust for observed selection bias using propensity score methods, with the degree of bias reduction reported for each predictor is described. The data used in this study come from the Florida K-20 Education Data Warehouse (FL-EDW) and the U.S. Department of Education's Common Core of Data (CCD). The subset of data from FL-EDW has student-level records for 20,373 students who participated in an IB Diploma Programme and graduated between 2002 and 2007, and student-level records for 86,008 randomly sampled students who did not participate in an IB Diploma Programme and graduated over the same time period. This study reveals that, when looking at the statewide population in Florida, the selection bias associated with voluntary participation in IB is very large, and that mechanisms for dealing with selection bias using propensity scores may not be sufficient. Tables and figures are appended.

- Abstract
As a critical step in understanding the impacts of IB, the analyses presented in this report examined the selection mechanisms behind IB participation across Florida, the state with the second highest representation of IB programs in the nation. We use longitudinal student and school-level data from 1995 through 2009 from the Florida K-20 Education Data Warehouse (EDW) to characterize individual students' educational histories from elementary school through high school and into college. To address issues of selection bias, we use propensity score methods (Rosenbaum & Rubin, 1983) to adjust for preexisting differences between IB and non-IB students. These analyses are designed to address the following research questions: (1) What are the student- and school-level predictors of participating in the IB Diploma Programme in Florida?; (2) To what degree does propensity score stratification or matching reduce selection bias associated with key student and school-level factors?; (3) What are the estimated differences in key postsecondary access indicators (i.e., SAT and ACT scores) and enrollment statistics (e.g., college selectivity) with and without different types of propensity score adjustments? Results revealed that, when looking at the statewide population in Florida, the selection bias associated with voluntary participation in IB is very large, and that mechanisms for dealing with selection bias using propensity scores may not be sufficient.

- Abstract
Background/Context: Financial aid is a critical policy lever for increasing college access, choice, and attainment. Even with the substantial investment in financial aid programs, however, inadequate financial resources continue to limit postsecondary educational attainment. The persistence of financial barriers despite the substantial annual investment in student financial aid programs suggests the need to better understand the role of financial aid in promoting college opportunity. Purpose: The study explores three questions: What are high school students' perceptions of and expectations for financial aid? How do these perceptions and expectations inform college-related behaviors? How are perceptions and expectations for financial aid influenced by the state and school contexts in which students are embedded? Research Design: The study uses data from descriptive case studies of 15 high schools, three in each of five states: California, Florida, Georgia, Maryland, and Pennsylvania. Within each state, we purposively selected three high schools. The three high schools, selected from one school district or metropolitan region, may be characterized as relatively "low," "middle," or "high" resource based on the demographic and academic characteristics of enrolled students. Conclusions/Recommendations: The results of this study suggest the importance of considering perceptions and expectations about aid, rather than actual amounts of available aid, when examining the relationship between financial aid and students' college-related decisions. The results also suggest that knowledge and understanding of aid are related to characteristics of the schools that students attend and characteristics of available aid (an aspect of the state context). In addition, the results indicate that perceptions of and expectations about aid may encourage students to engage in other behaviors that promote college access and success, particularly academic preparation. The article concludes by offering implications for future research.

- Abstract
This article uses descriptive analyses of data from the Integrated Postsecondary Education Data System to examine the status of equity for Hispanic students in public higher education institutions in Florida and Texas. The analyses show substantial inequities for Hispanics in enrollment, full-time faculty, and executive, administrative, and managerial staff. In both Texas and Florida, the greatest gaps in equity for Hispanics occur for full-time faculty and at the public flagship institutions. (Contains 6 tables and 1 note.)

- Abstract
While college enrollment rates have increased over the last 40 years, gaps still exist across groups. College enrollment rates are lower for high school graduates whose parents have not attended college, those with low-incomes, as well as Black and Latino/a students than for other high school graduates. One source of differences across groups in college-related outcomes is knowledge about college and financial aid. Research shows that the more information and guidance a student has, the more likely the student is to enroll in college. But, research also shows that a lack of knowledge about college, specifically financial aid, is prevalent in society today. This paper builds on prior research by exploring not only the sources of students' knowledge of college prices and financial aid, but also the nature and sources of other college-related knowledge and how this knowledge varies by school and state context. Specifically, this research extends prior work by assessing differences in student knowledge of financial aid, costs, college preparation and education needed, as well as the sources of this knowledge. It also examines how students' college-related knowledge varies based on particular aspects of the context, including the average socioeconomic status (SES) of students served by schools and the state policy environment. Drawing on a multi-level model of college enrollment and data from descriptive case studies of 15 high schools, this study explores the following guiding questions: (1) What do 9th and 11th grade students know about "college," including college prices, financial aid, academic requirements, and the type and amount of postsecondary education needed to fulfill their specific career aspirations?; (2) How do 9th and 11th grade students acquire college-related information?; and (3) How do college-related knowledge and sources of information vary across high schools and states? The findings from this study point to the lack of consistent mechanisms in most schools to channel information to students about the breadth of available educational opportunities available and the availability of financial aid and how to access it. The lack of sufficient structures to provide this information to students throughout their high school careers, while problematic for all students, is particularly likely to result in lower educational attainment for low-income students and those whose parents have not attended college.

- Abstract
This study describes how parental involvement not only is shaped by the school context but also shapes the school context for college opportunity. The study also describes the ways other aspects of context, particularly the higher education context and the state and economic context, shape parental involvement. Although parental encouragement and involvement appear to be important facilitators of college enrollment, this study describes the barriers that limit parental involvement not only for low-socioeconomic status parents but also for middle-SES parents. The study relies on data from descriptive case studies of 15 high schools, three in each of five states: California, Florida, Georgia, Maryland, and Pennsylvania. The five states were chosen based on their variation in economic, political, demographic, and educational characteristics. The authors developed data collection protocols based on the conceptual framework and a literature review of the predictors of college enrollment. Using the conceptual model as a guide, three themes emerge from the data: (a) parents shape college opportunity for their children, but involvement varies based on socioeconomic status; (b) parental involvement is shaped by, and also shapes, the school context for college opportunity; and (c) parental involvement is also shaped by the higher education context and the social, economic, and policy context. The findings from this study improve the understanding of the ways that parental involvement shape college enrollment for different families at different schools in different states. The findings suggest several implications for improving parental involvement.

- Abstract
In July 1999, green mussels were seen for the first time at Tampa Electric Company's (TECO) Gannon Station Power Plant (Gulf of Mexico, Hillsborough Bay portion of Tampa Bay, western coast of Florida) during routine maintenance of the seawater intake system. The mussels were identified as Perna viridis (Linnaeus 1758) based on shell and anatomical characters. This identification has been confirmed by cytological analysis. Perna viridis had previously not been found in the United States or in the Gulf of Mexico. Perna viridis is a native species in the Indian and Pacific Oceans and was discovered in the Caribbean Sea in Trinidad in 1990 and in Jamaica in 1998. The populations are widespread locally and well established: the largest specimen collected was estimated to be 15 months of age. This is the second species of Perna introduced to the Gulf of Mexico, joining Perna perna (Linnaeus 1758). which was discovered in Texas in 1990. Since the initial discovery of Perna viridis ill Tampa Bay, range surveys have found it as far north as John's Pass in St. Petersburg, Pinellas County, Florida and as far south as Boca Grande, Charlotte County, Florida.

- Abstract
In 1999, the green mussel, Perna viridis, was first observed in Tampa Bay, Florida. This was the first reported occurrence of this Indo-Pacific marine bivalve in North America. The mussels found in Tampa Bay were confirmed to be P. viridis based on both morphological and genetic characteristics. Since the initial discovery, surveys in Tampa Bay and on the West coast of Florida have documented the growth, recruitment, and range expansion of P. viridis. From November 1999 to July 2000, the mean shell length of a Tampa Bay population increased from 49.0 mm to 94.1 mm, an increase of 97%. Populations of P. viridis are successfully reproducing in Tampa Bay. Recruitment was observed on sampling plates in May and continued through July 2000. The full extent of mussel colonization is not clear, but mussels were found outside Tampa Bay in St. Petersburg, Florida, south to Venice. Based on these studies it is evident that P. viridis has successfully invaded Tampa Bay and the west coast of Florida. The long-term impact of P. viridis on native communities off the west coast of Florida cannot be predicted at this time. [ABSTRACT FROM AUTHOR]

- Abstract
The tropical Asian green mussel, Periza viridis (Bivalvia: Mytilidae) is a recent invader in the Caribbean Basin, including the subtropical southeastern United States. In this study we examined the (1) range of P. viridis in the southeastern United States, (2) relative abundance of P. viridis across habitats and (3) density of P. viridis in Tampa Bay, FL. The invasion and spread of P. viridis in the southeastern United States was estimated by a combination of first-hand qualitative sampling and second-hand observations. There were apparently at least two discrete introductions, each followed by natural dispersal. The initial invasion was discovered in Tampa Bay in 1999, and was followed by rapid spread of P. viridis south as far as Marco Island, FL, but limited spread northward. In 2002, a second invasion occurred in northeast Florida. separated from the west Florida population by 650 km of coastline. On the east coast, P. viridis appeared to be distributed discontinuously between South Carolina and the Indian River Lagoon, FL by 2007. The literature concerning native distribution, habitat use and invasion history, and vectors of P. viridis is also reviewed. [ABSTRACT FROM AUTHOR]

- Abstract
First-generation college students face unique challenges in higher education compared to students whose parents are college graduates. These students tend to come from lower socioeconomic backgrounds and face difficulty enrolling and persisting in higher education (Horn, 1998; Ishitani, 2003; Latino et al., 2018; Nunez & Cuccaro-Alamin, 1998; Warburton, Bugarin, & Nunez, 2001). They rely more on financial aid and employment to pay for college (Choy, 2001; Pratt, Harwood, Cavazos, & Ditzfeld, 2017), and are highly susceptible to attrition as a result of lacking the financial means to pay for college (Eitel & Martin, 2009). Postsecondary transition and academic support programs were designed to address factors affecting first-generation college student success, postsecondary transition and academic support programs (Almaraz et al., 2010; Kezar, 2000; Tate et al., 2015; Thayer, 2000; Walpole et al., 2008). Effective programs target students with the greatest financial need, assist students with navigating college, and adapt programming to student characteristics (Perna, 2015). Participants of these programs tend to have greater levels of student success compared to first-generation college students who do not participate (Ackermann, 1991; Almaraz et al., 2010; Carey, 2008; Garcia, 1991; McGlynn, 2009). At Florida State University (FSU), the Center for Academic Retention and Enhancement (CARE) is a comprehensive transition and academic support program designed to increase access and student success for first-generation college students. In 2015, FSU developed the CARE Grant to provide a minimum of 75% of the cost of attendance to CARE students in an effort to reduce the level of unmet financial need and increase student success. The purpose of the study was to explore the effects of awarding the grant-filled financial aid package on the persistence and academic achievement of first-generation college students enrolled in an academic support program. CARE provided a unique context to explore the effects of financial aid on academic performance and retention of students in an academic support program. This study is grounded in research relating to retention, first-generation college students, factors relating to their postsecondary persistence and academic success, transitional and academic support programs, financial aid and college costs, and relevant theories relating to the impact of financial aid and college costs on student retention. The research framework is influenced by Reason (2009), who developed a conceptual framework that included organizational context as an element contributing to retention. In the conceptual framework of this study, student demographics and pre-college characteristics contribute to a student's persistence at FSU through the context of CARE participation. Financial aid and college costs variables are additional influences to a student's persistence through to graduation.Through linear and binary logistic regression, the study analyzed the effects of multiple background, academic, and financial variables on FSU GPA, Overall GPA, and first-to-second year retention. The sample consisted of 1,425 students enrolled in CARE between summer 2013-2016 who reenrolled and received financial aid for the subsequent first term. The control group was students who enrolled in CARE in 2013 and 2014 who did not receive the CARE Grant. The study collected data on student GPAs and first-year retention to analyze the effects of the awarding the CARE Grant using data collection procedures native to FSU. The study's findings suggested the grant had no statistically significant effect on academic performance and retention when controlling for other variables. Only high school GPA was statistically significant and positive for both FSU GPA and Overall GPA. High school GPA and Black/African American classification were statistically significant and positively related to retention. The findings are significant in advancing knowledge of first-generation student success, financial aid, and postsecondary academic support programming. Recommendations for future research include examining graduation rates for the population studied, adding additional variables to better explore what elements contribute to academic performance and retention for CARE students, and using mixed methods research to capture additional qualitative factors influencing academic performance and retention.
