Community college faculty commitment to Florida performance -based funding indicators for academic programs

In 1996, the State of Florida implemented a performance-based funding program for the Associate in Arts degree offered by community colleges. Additional funds are allocated for distribution among public community colleges based on performance indicators. The indicators are comprised of 10 performance goals that refer to productivity indexed by overall degree completions as well as subgroups: special disadvantaged populations, transfers, job placements, and education acceleration. ^ This study examined the level of self-reported commitment of community college faculty to the 10 Florida performance-based funding indicators for academic programs. Also examined were the relationships between commitment and (a) self-efficacy in contributing to the achievement of the indicators and (b) personal financial reward expectation for contributing to the achievement of the indicators. The relationships between commitment and (a) gender, (b) academic rank, and (c) types of courses taught were analyzed based on secondary analyses. ^ The participants were 303 full-time faculty members of Miami-Dade Community College who taught courses taken by students pursuing the Associate in Arts degree. A questionnaire was developed to measure commitment, self-efficacy, and expectation of financial reward for each of the 10 indicators. ^ The mean composite commitment score for faculty members who responded to the survey was 4.07 in a scale of 1 to 5. Greater commitment was reported for indicators closely related to the traditional mission of community colleges (i.e., facilitating progress of special groups in earning the AA degree in preparation for transferring to a four-year university). Lower commitment was reported for indicators oriented to State priorities such as education acceleration mechanisms and job placements. Commitment was correlated with three variables: self-efficacy, expectation of financial reward, and types of courses taught. However, commitment was not related to gender and academic rank. Although a cause-effect relationship cannot be inferred from this study, the findings depict a positive relationship between faculty commitment to performance-based funding indicators and faculty self-efficacy to contribute to the achievement of the indicators. ^

Investigation into possible causes of elevated ozone concentrations in Miami, Florida

Ozone readings which exceeded the National Ambient Air Quality Standard of 120 ppbv were recorded in Miami, Florida during 1978 and 1980. Similar elevated concentrations of ozone extended across upper Florida and into the Southeastern portion of the United States. It is concluded that tropospheric transport of ozone into the Miami area occurs. This conclusion is supported by lead analyses of atmospheric samples taken in Miami and by isentropic trajectories. Six case studies are presented. In all cases transport of ozone into Florida appears to occur. In only four of the cases does this result in elevated ozone levels in Miami. In one case lower Florida was experiencing an oceanic influx of air and low ozone concentrations. In the other case Miami was experiencing a stagnation and high ozone concentrations apparently generated locally. The long range transport of ozone across the Southeastern United States appears to result from circulation within a weather pattern characterized by a stagnant high pressure system over the Southeastern United States.

Airborne Laser Quantification of Florida Shoreline and Beach Volume Change Caused by Hurricanes

This dissertation combines three separate studies that measure coastal change using airborne laser data. The initial study develops a method for measuring subaerial and subaqueous volume change incrementally alongshore, and compares those measurements to shoreline change in order to quantify their relationship in Palm Beach County, Florida. A poor correlation (R2 = 0.39) was found between shoreline and volume change before the hurricane season in the northern section of Palm Beach County because of beach nourishment and inlet dynamics. However, a relatively high R2 value of 0.78 in the southern section of Palm Beach County was found due to little disturbance from tidal inlets and coastal engineering projects. The shoreline and volume change caused by the 2004 hurricane season was poorly correlated with R2 values of 0.02 and 0.42 for the north and south sections, respectively. The second study uses airborne laser data to investigate if there is a significant relationship between shoreline migration before and after Hurricane Ivan near Panama City, Florida. In addition, the relationship between shoreline change and subaerial volume was quantified and a new method for quantifying subaqueous sediment change was developed. No significant spatial relationship was found between shoreline migration before and after the hurricane. Utilization of a single coefficient to represent all relationships between shoreline and subaerial volume change was found to be problematic due to the spatial variability in the linear relationship. Differences in bathymetric data show only a small portion of sediment was transported beyond the active zone and most sediment remained within the active zone despite the occurrence of a hurricane. The third study uses airborne laser bathymetry to measure the offshore limit of change, and compares that location with calculated depth of closures and subaqueous geomorphology. There appears to be strong geologic control of the depth of closure in Broward and Miami-Dade Counties. North of Hillsboro Inlet, hydrodynamics control the geomorphology which in turn indicates the location of the depth of closure.

Problems faced by beginning principals

The job of a principal is becoming more demanding and more critical each year. Principals are asked to undertake huge challenges and to succeed regardless of what obstacles lie ahead. The purpose of this study was to identify which Administrative Task Areas and Specific Task Areas caused the most difficulties for first- and second-year principals.^ A survey was taken of first- and second-year principals in Dade County, Florida. These beginning principals rated their level of proficiency for each administrative task area and each specific task within those areas. Participants rated their perceptions on a scale from one to four. The data were analyzed based on frequency distributions, percentages, means, and standard deviations.^ Beginning principals perceived themselves as least proficient in the administrative task areas of management and personnel duties. They believed their strongest areas were curriculum and instruction and school-community relations. Within these areas, the specific administrative task areas identified as most problematic were identifying proper procedures for construction in the schools, visiting classrooms to help teachers improve instruction, awareness of issues related to school law, establishing accounting procedures for the school's internal funds, and procedures for dismissing incompetent staff members.^ Many beginning principals surveyed volunteered to make recommendations for future beginning principals. Of these recommendations, the most popular responses addressed obtaining more experience with the budget and internal funds prior to becoming a principal. In addition, there was a strong need for more training dealing with school personnel and the importance of networking with a veteran principal.^ The principal training programs for five of the largest school districts in Florida were reviewed. These programs were found to incorporate a vast amount of the recommendations included in the literature. Florida is moving in the right direction toward excellence in the public schools. ^

Regional growth, structural change, and natural disaster

Hurricanes, earthquakes, floods, and other serious natural hazards have been attributed with causing changes in regional economic growth, income, employment, and wealth. Natural disasters are said to cause; (1) an acceleration of existing economic trends; (2) an expansion of employment and income, due to recovery operations (the so-called silver lining); and (3) an alteration in the structure of regional economic activity due to changes in "intra" and "inter" regional trading patterns, and technological change.^ Theoretical and stylized disaster simulations (Cochrane 1975; Haas, Cochrane, and Kates 1977; Petak et al. 1982; Ellson et al. 1983, 1984; Boisvert 1992; Brookshire and McKee 1992) point towards a wide scope of possible negative and long lasting impacts upon economic activity and structure. This work examines the consequences of Hurricane Andrew on Dade County's economy. Following the work of Ellson et al. (1984), Guimaraes et al. (1993), and West and Lenze (1993; 1994), a regional econometric forecasting model (DCEFM) using a framework of "with" and "without" the hurricane is constructed and utilized to assess Hurricane Andrew's impact on the structure and level of economic activity in Dade County, Florida.^ The results of the simulation exercises show that the direct economic impact associated with Hurricane Andrew on Dade County is of short duration, and of isolated sectoral impact, with impact generally limited to construction, TCP (transportation, communications, and public utilities), and agricultural sectors. Regional growth, and changes in income and employment reacted directly to, and within the range and direction set by national economic activity. The simulations also lead to the conclusion that areal extent, infrastructure, and sector specific damages or impacts, as opposed to monetary losses, are the primary determinants of a disaster's effects upon employment, income, growth, and economic structure. ^

Effect of an inservice on the teachers' knowledge of general school law, Section 504, and the Meta Consent Decree

It is generally assumed by educators that inservice training will make a significant difference in teacher knowledge of topics related to education. This investigation addressed that assumption by examining the effects of various factors, e.g., amount and timing of inservice training, upon teacher knowledge of educational law. Of special interest was teacher knowledge of the law as it pertained to ethnic and other characteristics of students in urban school settings. This study was deliberately designed to determine which factors should be later investigated in a more deterministic form, e.g., an experimental design.^ The investigation built upon that of Ogletree (1985), Osborne (1996) and others who focused on the importance of teacher development as a method to enhance professional abilities. The main question addressed in this study was, "How knowledgeable are teachers of school law, especially with regard to general school law, the Meta Consent Decree and Section 504 of the Rehabilitation Act of 1973."^ The study participants (N = 302) were from the Dade County School System, the fourth largest in the U.S. The survey design (approved by the System), specified participants from all levels and types of schools and geographic representations. A survey instrument was created, pilot tested, revised and approved for use by the district official representatives. After administration of the instrument, the resultant data was treated by several appropriate tests, e.g., multivariate analysis of variance (ANOVA).^ Several findings emerged from the analysis of the data: in general, teachers did not have sufficient knowledge of school law; factors, such as amount and level of education, and status and position were positively correlated with increased knowledge; factors such as years of experience, gender, race and ethnicity were not correlated with higher levels of knowledge. The most significant, however, was that when teachers had participated in several inservice training experiences, typically workshops, and, when combined with other factors noted above, their knowledge of school law was significantly higher. Specific recommendations for future studies were made. ^

A worksite nutrition education program increased firefighters' knowledge and resulted in healthier attitudes toward fad diets

The effectiveness of a worksite nutrition education program to improve firefighters' knowledge and weight management strategies was evaluated. One hundred fifty Miami-Dade Fire Rescue workers recruited for the study were randomly assigned to an intervention or a control group. The intervention group attended four 30-minute worksite nutrition education sessions. A nutrition knowledge test completed by both groups before and after the intervention showed no significant differences between groups for pre-intervention nutrition knowledge. The post-intervention increase in nutrition knowledge was significantly greater (p < 0.001) for the intervention group (16.8% ± 8.2) compared to the control group (4% ± 8.9). No significant pre-intervention difference was found between the groups' predilection toward a ketogenic diet. A statistically significant (p < 0.01) reduction was seen in the intervention group's willingness (0.57 ± 1.06) to use this diet compared to the control group (0.02 ± 0.99). Results indicate that worksite nutrition education can improve firefighters' knowledge and weight reduction strategies. ^

Estimation of average annual daily traffic (AADT) using geographically weighted regression (GWR) method and geographic information system (GIS)

Annual average daily traffic (AADT) is important information for many transportation planning, design, operation, and maintenance activities, as well as for the allocation of highway funds. Many studies have attempted AADT estimation using factor approach, regression analysis, time series, and artificial neural networks. However, these methods are unable to account for spatially variable influence of independent variables on the dependent variable even though it is well known that to many transportation problems, including AADT estimation, spatial context is important. ^ In this study, applications of geographically weighted regression (GWR) methods to estimating AADT were investigated. The GWR based methods considered the influence of correlations among the variables over space and the spatially non-stationarity of the variables. A GWR model allows different relationships between the dependent and independent variables to exist at different points in space. In other words, model parameters vary from location to location and the locally linear regression parameters at a point are affected more by observations near that point than observations further away. ^ The study area was Broward County, Florida. Broward County lies on the Atlantic coast between Palm Beach and Miami-Dade counties. In this study, a total of 67 variables were considered as potential AADT predictors, and six variables (lanes, speed, regional accessibility, direct access, density of roadway length, and density of seasonal household) were selected to develop the models. ^ To investigate the predictive powers of various AADT predictors over the space, the statistics including local r-square, local parameter estimates, and local errors were examined and mapped. The local variations in relationships among parameters were investigated, measured, and mapped to assess the usefulness of GWR methods. ^ The results indicated that the GWR models were able to better explain the variation in the data and to predict AADT with smaller errors than the ordinary linear regression models for the same dataset. Additionally, GWR was able to model the spatial non-stationarity in the data, i.e., the spatially varying relationship between AADT and predictors, which cannot be modeled in ordinary linear regression. ^

Investigation of the causes of serious injury and fatal crashes: An analysis using econometric models

The rate of fatal crashes in Florida has remained significantly higher than the national average for the last several years. The 2003 statistics from the National Highway Traffic Safety Administration (NHTSA), the latest available, show a fatality rate in Florida of 1.71 per 100 million vehicle-miles traveled compared to the national average of 1.48 per 100 million vehicle-miles traveled. The objective of this research is to better understand the driver, environmental, and roadway factors that affect the probability of injury severity in Florida. ^ In this research, the ordered logit model was used to develop six injury severity models; single-vehicle and two-vehicle crashes on urban freeways and urban principal arterials and two-vehicle crashes at urban signalized and unsignalized intersections. The data used in this research included all crashes that occurred on the state highway system for the period from 2001 to 2003 in the Southeast Florida region, which includes the Miami-Dade, Broward and Palm Beach Counties.^ The results of the analysis indicate that the age group and gender of the driver at fault were significant factors of injury severity risk across all models. The greatest risk of severe injury was observed for the age groups 55 to 65 and 66 and older. A positive association between injury severity and the race of the driver at fault was also found. Driver at fault of Hispanic origin was associated with a higher risk of severe injury for both freeway models and for the two-vehicle crash model on arterial roads. A higher risk of more severe injury crash involvement was also found when an African-American was the at fault driver on two-vehicle crashes on freeways. In addition, the arterial class was also found to be positively associated with a higher risk of severe crashes. Six-lane divided arterials exhibited the highest injury severity risk of all arterial classes. The lowest severe injury risk was found for one way roads. Alcohol involvement by the driver at fault was also found to be a significant risk of severe injury for the single-vehicle crash model on freeways. ^

Parental involvement: Its relation to achievement in a multiethnic sample of newly immigrated students

The current study examined how parental involvement is related to the academic adaptation and performance of a multiethnic sample of newly immigrant students from South America and the Caribbean---Argentina, Colombia, Cuba, Haiti, and English-speaking Caribbean countries. Six hundred twenty-two participants attending elementary, middle and high school in Miami-Dade and Broward Counties were interviewed during two consecutive years at their respective schools. Parents completed surveys at home and returned them by mail. ^ Three forms of parent involvement were chosen as predictor variables---(1) parental contact and communication with school, (2) parental monitoring of children's school-related activities at home, and (3) parental expectations regarding children's academic achievement. Academic performance indicators obtained from school records were students' grade point averages for math and reading (GPA), FCAT-SSS (Florida Comprehensive Assessment Test-Sunshine State Standards) scores, and FCAT-NRT (Norm Referenced Test) scores. Hypotheses were (a) that the forms of parent involvement would differ across the different cultural groups and (b) that parent involvement would relate to students' achievement, regardless of the specific form of involvement. ^ Results indicated that Cuban and Colombian parents differed significantly in terms of monitoring school-related activities of their children and had higher expectations for their children than Haitian, West-Indian, or Argentinean parents. Cuban parents were more likely to be actively engaged in communication with their children's schools than parents of the other ethnic groups. Multiple regression analyses indicated that the three forms of parent involvement accounted for a significant proportion of GPA and FCAT-SSS scores, after controlling for the effects of demographic variables---grade level, gender, and ethnicity. Given interactions of the parent involvement variables by country of origin for GPA, separate analyses indicated that parent involvement appeared to be most effective for Cubans and West Indians. Results are discussed in terms of the need for experimental intervention studies to identify causal relationships between parent involvement and academic achievement. ^

Assessing administrative and political factors in implementing a living wage ordinance

Since 2000, the number of living wage ordinances has steadily increased throughout the country. While most of the current research has focused on the beneficial outcomes of living wages, little has been published on their administrative practices. To address this shortcoming, this study focused on the identification of key administrative and political factors involved impacting the implementation of living wage ordinances in Miami-Dade and Broward Counties. The study utilized a triangulation of interviews, surveys, and direct observation. The author conducted interviews of administrators and members of the living wage oversight boards in both counties and observed the monthly meetings held by each county's oversight board from January 2006 to June 2007. These findings were buttressed with a national survey of senior staff in other living wage communities. The study utilized descriptive statistics, Chi Square, Cronbach's Alpha, and Spearman's Rank Correlation Coefficient (Spearman's rho). Interviews indicated that administrators in Dade and Broward are seriously under-staffed and budgeted. Ambiguities in the enabling ordinances have lead to loopholes that undermine implementation and accountability for participating contractors. Survey results showed that policy ambiguity, organizational politics, and a lack of organizational capacity were significant negative factors in the implementation process while an organizational culture emphasizing consistent enforcement was a positive factor. Without the proper inputs, an organization hinders itself from meeting its outputs and outcomes. This study finds that Broward and Miami-Dade Counties do not provide the necessary administrative support to implement a living wage effectively – in stark contrast to the high hopes and strong political support behind their passage. For a living wage to succeed, it first needs an organizational culture committed to providing the necessary resources for implementation as well as transparent, consistent accountability mechanisms.

Spatial and Temporal Changes in Groundwater Salinity in South Florida

A combination of statistical and interpolation methods and Geographic Information System (GIS) spatial analysis was used to evaluate the spatial and temporal changes in groundwater Cl− concentrations in Collier and Lee Counties (southwestern Florida), and Miami-Dade and Broward Counties (southeastern Florida), since 1985. In southwestern Florida, the average Cl− concentrations in the shallow wells (0–43 m) in Collier and Lee Counties increased from 132 mg L−1 in 1985 to 230 mg L−1 in 2000. The average Cl− concentrations in the deep wells (>43 m) of southwestern Florida increased from 392 mg L−1 in 1985 to 447 mg L−1 in 2000. Results also indicated a positive correlation between the mean sea level and Cl− concentrations and between the mean sea level and groundwater levels for the shallow wells. Concentrations in the Biscayne Aquifer (southeastern Florida) were significantly higher than those of southwestern Florida. The average Cl− concentrations increased from 159 mg L−1 in 1985 to 470 mg L−1 in 2010 for the shallow wells (<33 m) and from 1360 mg L−1 in 1985 to 2050 mg L−1 in 2010 for the deep wells (>33 m). In the Biscayne Aquifer, wells showed a positive or negative correlation between mean sea level and Cl− concentrations according to their location with respect to the saltwater intrusion line. Wells located inland behind canal control structures and west of the saltwater intrusion line showed negative correlation values, whereas wells located east of the saltwater intrusion line showed positive values. Overall, the results indicated that since 1985, there was a potential decline in the available freshwater resources estimated at about 12–17% of the available drinking-quality groundwater of the southeastern study area located in the Biscayne Aquifer.

Relevance of the community college curriculum to the international student

The purpose of this study was to ascertain the perception of the level of satisfaction that international students have regarding the services and the relevance of the curriculum offered at Miami-Dade Community College. Trends and issues at universities and community colleges in providing services and an international curriculum for foreign students are outlined. Focus is on characteristics, personal and career needs as well as needs of national development for the students' countries. A sample of students from four developing nations was selected to qualitatively and quantitatively determine their level of satisfaction. The nations are the Bahamas, Colombia, Haiti and Pakistan. Students responses were recorded through group interviews, four personal interviews, an open ended questionnaire and a Likert scaled survey questionnaire. Matrix charts, mean calculations and one way analysis of variance were used to analyze data collected. Country of origin and major program of study were the variables used for statistical analysis. Information gathered through qualitative research presented a variety of perspectives and responses, both positive and negative. Students supplied specific examples of experiences and insights to help explain their various perceptions. Statistically, there were no significant differences between the variables of country of origin and major program of study regarding program services and relevance of the curriculum. Implications and recommendations for community college programs were outlined.
