As cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production. Because urban food production on private land, such as backyards, requires the willing participation of landowners, resident's feelings about and experience with food growing are important to understand. The demographic groups that were most likely to food garden were those in long-term relationships, higher income brackets, those with college education and residents over 50 years old. Incentives and programs focused on producing more from existing gardens may be most appropriate for people in these demographic groups, while other groups will most require basic food growing information. Study participants highly valued intangible benefits of food gardening (e.g., relaxation, feelings of happiness and satisfaction), often more than the provision of food. Most barriers and problems with backyard food growing, such as a lack of space and the need for gardening information, were similar for those who food garden and those who do not. Results from this study indicate that traditional agricultural incentives and perspectives must be rethought if they are to be applied in urban settings. By creating incentives and initiatives that reflect the needs and challenges faced by urban growers, urban agriculture will become an integrated part of the community, improving food quantity and quality while enriching residents' lives.

The recent financial crisis which has beset the United States has made itself felt in a number of ways, not the least of which has been its adverse effect on the housing market. As foreclosure percentages accelerated, increasing numbers of properties across the country became empty and abandoned, leaving a visible imprint of deterioration in neighborhoods that were significantly affected. Initial GIS analysis of both foreclosed and non-foreclosed residential land in Broward County Florida was conducted, showing that there is a discernible spectral difference in the lawn space of these two types of properties, with foreclosed properties exhibiting more brownness, or loss of green space. In order to evaluate whether or not this visible deterioration has had an effect on residents left behind in areas of foreclosure and their own habits, 950 mail-in surveys were distributed throughout 19 different census tracts in Broward County, inquiring about demographics, surrounding foreclosures, degrees of concern for home value and appearance, and changes in lawn maintenance since the foreclosure crisis along with reasons for such change if such exists. Data received from respondents was then analyzed in order to identify any attributes or correlations which might contribute to further neighborhood change, and how any of these factors might be affecting attitudes or perceptions of those left behind, as well as their lawn maintenance habits.

South Florida's loggerhead (Caretta caretta), green (Chelonia mydas) and leatherback (Dermochelys coriacea) sea turtles hatchling have environmentally determined sex. The in situ nest mean hatchling sex ratios (SR) were highly female-biased : loggerhead F=0.89) and green turtle F=0.81; leatherback's SR was nearly balanced (0.55F). Nest temperatures and SRs differed between leatherbacks and loggerhead and green turtles. The latter two did not differ. The loggerhead response parameters were estimated within biological limitations by both 50-65% of incubation and mean middle 1/3 temperature. The maximum middle 1/3 temperature was the best-fit predictor for green turtles. No best-fit sex ratio-temperature response could be identified for leatherbacks. Clutches incubating under natural conditions can vary greatly in SR ; TRT differences may account for differences among species' sex ratios.

With more and more focus on accountability, algebra achievement has become a major focus of math curriculum developers. In many states, students are expected to pass standardized Algebra achievement tests in order to satisfy graduation requirements. The purpose of this study was to identify teacher qualities and teaching qualities linked to teacher effectiveness in 7th-grade Algebra I Honors. This study examined two aspects of teachers, teacher quality and teaching quality. Teacher quality refers to the characteristics that teachers possess and teaching quality refers to what teachers do in the classroom to foster student learning. For this study, teacher quality included teacher professional preparation characteristics and teacher knowledge. Also, aspects of teaching quality that promote conceptual understanding in Algebra were examined. The difference between more and less effective teachers in this study lies in teaching quality, what teachers do in the classroom, as opposed to teacher quality, what those teachers bring with them to the classroom. The findings of this study indicate that elements of teaching quality are more indicative of teacher effectiveness than elements of teacher quality among teachers in the study. Although there was some evidence of a relationship between elements of teacher quality and teacher effectiveness, there were clear differences in teaching quality among more effective and less effective teachers in this study.

Ports and container terminals have very complex and dynamic operations. Effective and efficient berth schedules are essential for profitable and sustainable operations. This research studies berth scheduling under uncertainties in arrival and handling times. Port operators usually face challenges in the development of berth schedules. This thesis presents a model formulation of discrete berth space that accounts for uncertainty in arrival and handling times. The problem is reformulated as a biobjective bi-level optimization berth scheduling problem. A solution approach is presented using evolutionary algorithms and heuristics. The objective of the formulation is to provide a robust berth schedule by minimizing the average and the range of the total service times for all vessels served at the terminal. Simulation is utilized to evaluate the proposed berth scheduling policy and compare it to two first-come-first-served policies. Results showed that the proposed berth schedules outperform under high congestion.

The Chief Research Administrator (CRA), also known as the Vice President, Vice Provost, or Vice Chancellor for Research, plays a key role in the research university. It is a position of power and not only affects the mission of the institution, but also controls a very large and vital percentage of external funding. The lack of information on how to prepare for the position makes it difficult to plan a career path for those who aspire to the position. This study was designed to obtain information to define the persona and career path(s) of the CRA at research universities in the United States. Survey data related to career pathways resulted in the emergence of four main pathways; Faculty/Academic, Administrative, Private Industry, and a Combination of the first three pathways. The results indicated that the most highly cited pathway to the position of the CRA was the Faculty/Academic (83%). The least traveled pathway to the position of CRA was found to be Administrative, that is, beginning at the lowest levels of a research office or administrative position and progressing through the ranks of the research office.

This study was designed to measure the relation of education and ethnic identity to attitudes towards bilingualism in two different ethnic groups, Asian and Latinos in the United States. In order to do this, an instrument was developed to measure attitudes towards bilingualism. No significant relations were found among education or ethnic identity and attitudes towards bilingualism in either group, but analyses revealed several other significant relationships. The two subscales of ethnic identity, MEIM-R Commitment and Exploration, were related to each other both within Asian and Latino groups and in all participants combined. In the combined sample, education levels of participants' mothers was correlated with the MEIM-R subscale of Exploration. In addition, participants with a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Commitment than participants with an Associates Degree or below. Participants with mothers who possess a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Exploration than participants with mothers who possess an Associates Degree or below. Finally, Asian participants were found to have lower levels of MEIM-R Commitment when compared to Latino participants.

I examine the impact of real earnings management (REM) and corporate governance on cash holdings. Extant research documents an increase in both cash holdings and REM activity in recent years and shows that agency conflicts influence both the levels and valuations of cash holdings. Motivated by agency problems of REM and Jensen's (1986) arguments concerning the free cash flow problem, I investigate whether opportunistic asset sales and reductions in discretionary expenditures are associated with levels and valuations of cash holdings. Prior research also shows that strong corporate governance mitigates opportunistic earnings management behavior and enhances the valuation of cash holdings. Using empirical models from prior research, I document that REM is positively associated with cash holdings, investors discount cash holdings of high REM firms, and, among high REM firms, valuations of cash holdings of weak corporate governance firms are discounted significantly lower relative to those of strong corporate governance firms. My study unites two lines of research by incorporating agency problems concerning REM with levels and valuations of cash holdings.

Edith Wharton uses characterization in the primary three characters in The Age of Innocence to explore the aspects of her life. Early adulthood is represented by May Welland Archer, who was born into New York 400, where society suppressed an individual's emotions, aspirations, and freedoms. The intermediate phase of her life is depicted in Newland Archer, who tests the confining limits of the society to which he belongs and strives to understand the role of emotions in achieving personal satisfaction. Wharton rejected and craved the ties of the New York 400 in the final phase of her life as portrayed in Ellen Olenska who left the 400, lived in Europe, and returned to New York. By developing these characters, Wharton attempts to retrospectively reconcile the transformations she experienced. Indeed, it will be clear that Wharton's work serves as a personal assessment of her self-actualization.
