This dissertation focuses on entrepreneurial and business performance indicators as determinants of Arizona charter schools' quality. The study utilizes a mixed-method inquiry with focus on qualitative research, exploration, and implementation studies. It draws data from surveys with charter operators performed by Education Team Partners (ETP). All survey results are drawn from the ETP database. The study reviews the genesis and evolution of charter schools. It reviews the social agreement within the context of public policy analysis, and the public-private partnership nature within the context of entrepreneurship and business management. It attempts to develop a research-based foundation for future action research to complement the newly introduced performance management plan (PMP) measurement and evaluation system in Arizona. The research includes four group indicators for measuring charter schools' business productivity and performance. They are studied in relation to three groups of indicators for measuring charter schools' quality. The case studies include two existing and two future charter schools. Study results indicate that all participating charter operators confirm the significance of the liquidity ratio in relation to any aspect of charter school quality covered in this study. The participants indicated a strong relationship between the capacities of their schools to utilize external resources and all indicators of charter school quality. This study draws two important conclusions. First, charter schools are business organizations, despite the fact that they receive public funds. Operationally, they differ substantially from district schools and government agencies and depend on market forces. Second, charter schools cannot survive inefficient management practices, as market forces tend to drive them out of business, regardless of academic success and student achievement levels. The intended implications from this study include: first, increased awareness about the importance of understanding business indicators in relation to charter school quality; second, the need for more research associated with the business and finance components of charter schools. As the body of collective knowledge about charter schools expands, the relationship between various business indicators to measures of quality should be routinely studied within larger populations, which may allow for an improved measurement system and applications of advanced statistical methods.

Leonard Hayflick studied the processes by which cells age during the twentieth and twenty-first centuries in the United States. In 1961 at the Wistar Institute in the US, Hayflick researched a phenomenon later called the Hayflick Limit, or the claim that normal human cells can only divide forty to sixty times before they cannot divide any further. Researchers later found that the cause of the Hayflick Limit is the shortening of telomeres, or portions of DNA at the ends of chromosomes that slowly degrade as cells replicate. Hayflick used his research on normal embryonic cells to develop a vaccine for polio, and from HayflickÕs published directions, scientists developed vaccines for rubella, rabies, adenovirus, measles, chickenpox and shingles.
Although best known for his work with the fruit fly, for which he earned a Nobel Prize and the title "The Father of Genetics," Thomas Hunt Morgan's contributions to biology reach far beyond genetics. His research explored questions in embryology, regeneration, evolution, and heredity, using a variety of approaches.
