The United States is home to a private prison industry, which allows for the detention of human beings to be transformed into a multi-billion dollar industry. This paper traces the parallels between the post-civil war convict leasing system and the current system of prison privatization, which encourages the commodification of black bodies in order to maintain a racial hierarchy. It analyzes the incompatibility of prison privatization with the US Constitution. Private prisons, which hold African American men at a higher rate that state-run prisons, take cost-cutting measures in order to increase profit, which expose prisoners to higher rates of abuse and increased recidivism rates. Private prisons have significant political power to determine crime control legislation, which has led to harsh laws which increase the number of men of color behind bars. This paper provides a three-phase plan for abolishing private prisons and reducing overall incarceration rates in the United States.

The strong impact of non-native predators in aquatic systems is thought to relate to the evolutionary naiveté of prey. Due to isolation and limited dispersal, this naiveté may be relatively high in freshwater systems. In this study, we tested this notion by examining the antipredator response of native mosquitofish, Gambusia holbrooki, to two non-native predators found in the Everglades, the African jewelfish, Hemichromis letourneuxi, and the Mayan cichlid, Cichlasoma urophthalmus. We manipulated prey naiveté by using two mosquitofish populations that varied in their experience with the recent invader, the African jewelfish, but had similar levels of experience with the longer-established Mayan cichlid. Specifically, we tested these predictions: (1) predator hunting modes differed between the two predators, (2) predation rates would be higher by the novel jewelfish predator, (3) particularly on the naive population living where jewelfish have not invaded yet, (4) antipredator responses would be stronger to Mayan cichlids due to greater experience and weaker and/or ineffective to jewelfish, and (5) especially weakest by the naive population. We assayed prey and predator behavior, and prey mortality in lab aquaria where both predators and prey were free-ranging. Predator hunting modes and habitat domains differed, with jewelfish being more active search predators that used slightly higher parts of the water column and less of the habitat structure relative to Mayan cichlids. In disagreement with our predictions, predation rates were similar between the two predators, antipredator responses were stronger to African jewelfish (except for predator inspections), and there was no difference in response between jewelfish-savvy and jewelfish-naive populations. These results suggest that despite the novelty of introduced predators, prey may be able to respond appropriately if non-native predator archetypes are similar enough to those of native predators, if prey rely on general antipredator responses or predation cues, and/or show neophobic responses.

Non-native predators may have negative impacts on native communities, and these effects may be dependent on interactions among multiple non-native predators. Sequential invasions by predators can enhance risk for native prey. Prey have a limited ability to respond to multiple threats since appropriate responses may conflict, and interactions with recent invaders may be novel. We examined predator–prey interactions among two non-native predators, a recent invader, the African jewelfish, and the longer-established Mayan cichlid, and a native Florida Everglades prey assemblage. Using field enclosures and laboratory aquaria, we compared predatory effects and antipredator responses across five prey taxa. Total predation rates were higher for Mayan cichlids, which also targeted more prey types. The cichlid invaders had similar microhabitat use, but varied in foraging styles, with African jewelfish being more active. The three prey species that experienced predation were those that overlapped in habitat use with predators. Flagfish were consumed by both predators, while riverine grass shrimp and bluefin killifish were eaten only by Mayan cichlids. In mixed predator treatments, we saw no evidence of emergent effects, since interactions between the two cichlid predators were low. Prey responded to predator threats by altering activity but not vertical distribution. Results suggest that prey vulnerability is affected by activity and habitat domain overlap with predators and may be lower to newly invading predators, perhaps due to novelty in the interaction.

The purpose of this research is to develop a broader understanding of the system in Florida. Specifically, I am looking at the privatization of convict labor programs by the Prison Rehabilitative Industries and Diversified Enterprises Corporation (PRIDE) in the 1980s and 1990s in state correctional institutions. This research will contribute to historiography of prisons in Florida in the context of the developing research about the Prison-Industrial Complex. Many scholars studying the Prison-Industrial Complex have drawn comparisons to today’s prison industries and the convict lease system of the late 19th and early 20th centuries, seeing the prison system go full circle drawing attention to the exploitative and institutionally racist nature of the modern prison system. This researched showed that the trend other scholars have studied also exist in Florida and Florida was actually a pioneer in the Prison-Industrial Complex. It was the first state to privatize its convict labor programs, becoming a model for other states. This research also shows that political and economic motivations were the primary forces governing prison policies, rather than education, rehabilitation, and safety. To complete this project, I analyzed articles from South Florida newspapers, such as the Sun-Sentinel and the Miami Herald, published during this period as well as literature published by the Department of Corrections. The United States has the highest rate of incarceration in the world and spends more money on prisons than education. Being such a large part of country, prisons warrant more critical study. This research will shed light on the nature of prisons, specifically here in Florida, in the hopes of seeking alternatives.

Too beautiful for thieves and pickpockets: a history of the Victorian convict prison on Spike Island
Resumo:
Spike Island holds a unique place among the world’s prisons: a welcome necessity for the prison authorities of Ireland, a remote and dangerous posting for its staff, a grand hell for those convicted to stay behind its walls. For almost four decades the Victorian prison on Spike Island was home to Ireland’s most serious and notorious criminals. Established in the midst of one of the worst famines in global history, this huge facility became the largest prison in what was then the United Kingdom, dwarfing institutions like Dartmoor, Pentonville, Mountjoy and Kilmainham. High death rates during its formative years meant that many of its malnourished inmates were laid to rest beneath its sod. Yet Spike Island was to become a beacon of penal reform, influencing modern correctional systems in countries as far apart as the USA and Germany. The story told in this book is one that is, in turn, dramatic, shocking, touching and humorous. The life of the prison was vibrant, peopled by the unfortunate of the society alongside those who committed serious, sometimes gruesome, crimes. This is the story of the establishment and evolution of the prison over 36 years, the often fascinating lives of prisoners and staff and of a time when a renowned Irish fortress of British military power entered the annals of penal infamy.
