A preliminary transient-fault experiment on the SIFT computer system

This paper presents the results of a preliminary experiment to study the effectiveness of a fault-tolerant system's ability to handle transient faults. The primary goal of the experiment was to develop the techniques to measure the parameters needed for a reliability analysis of the SIFT computer system which includes th effects of transient faults. A key aspect of such an analysis is the determination of the effectiveness of the operating system's ability to discriminate between transient and permanent faults. A detailed description of the preliminary transient fault experiment along with the results from 297 transient fault injections are given. Although not enough data was obtained to draw statistically significant conclusions, the foundation has been laid for a large-scale transient fault experiment

Crime, community and police in Cape Town, 1825-1850

Bibliography: pages 184-192.This thesis is primarily an examination of petty crime and law enforcement in Cape Town in the period 1825 -1850. This period was one of fundamental change in terms of the spatial and demographic growth of Cape Town, the diversifying economy and the changing legal status of firstly the Khoi and subsequently the slaves. These developments had significant ramifications on the level and nature of crime, and perceptions of crime and criminals. The creation of a technically 'free' population and the transition from slave to wage labour engendered a great deal of alarm among Cape Town's dominant classes. That they felt their dominance and hegemony threatened by the potentially challenging White, Khoi and Black under classes, entailed a re-assertion of their power. Control mechanisms instituted in response to this included the abortive Vagrancy Ordinance of 1834, the Masters and Servants' Ordinance of 1841, a revamped police force in 1840 and varying social control stratagems. These were all designed to bolster the power of the dominant classes and mould a pliable labour force inculcated with the morality of the dominant classes. The under classes proved very adept at side stepping the imposition of control. In this they were often unwittingly aided by the grossly unprofessional and incompetent police. The ascendancy of the dominant classes, however, was temporarily frustrated but never totally checked. Similar studies of crime and law enforcement in 19th Century Britain have greatly informed the manner in which this thesis was tackled, but the nature of the source material in Cape Town has necessitated a somewhat different approach. The incomplete nature of the Court Record Books meant that a statistical analysis was impossible. More fruitful data were the letter books of personnel and institutions involved in the running of Cape Town; the Superintendent of Police, the Attorney-General, Resident Magistrate and the Municipality. For more general attitudes letters to and editorials in the local press proved to be an invaluable key to an understanding of the mores and perceptions of the dominant classes

Food purchasing behaviors, dietary energy density, perceived health status, and perceived nutrition knowledge of female food stamp recipients living in Southeast Louisiana

Purchase and consumption of energy-dense nutrient poor [EDNP] foods by low-income individuals contributes to the lower diet quality and increased risk of chronic disease (e.g. obesity, type 2 diabetes) in this population. Food purchasing behaviors, dietary energy density [ED], perceived health status, and perceived nutrition knowledge were assessed in 22 female food stamp recipients in Southeast Louisiana. Two 24-hour recalls (at the beginning and at the end of the month) and food expenditure receipts were collected; participants also completed several questionnaires. Fifty percent [%] (n=11) of study participants were food secure, and fifty percent (n=11) were food insecure. Sixty-four % (n=14) of study participants were obese. Perceived nutrition knowledge was significantly associated with body mass index [BMI] (p=0.021) and with monthly expenditures on EDNP foods (p=0.076). A significant association of perceived eating habits with BMI was found (p=0.023). Age was significantly associated with monthly expenditures on EDNP foods (p=0.007), monthly fast food consumption (p=0.090), and perceived physical health (p=0.086). Food security status significantly influenced monthly expenditures on EDNP foods (p=0.007) and monthly fast food consumption (p=0.095), but did not significantly influence BMI or perceived physical health. Income per person in the household was also found to significantly influence perceived physical health (p=0.060). The impact of food purchasing behaviors and dietary energy density on the health of female food stamp recipients in Louisiana should be studied further

User's guide to programming fault injection and data acquisition in the SIFT environment

Described are the features, command language, and functional design of the SIFT (Software Implemented Fault Tolerance) fault injection and data acquisition interface software. The document is also intended to assist and guide the SIFT user in defining, developing, and executing SIFT fault injection experiments and the subsequent collection and reduction of that fault injection data. It is also intended to be used in conjunction with the SIFT User's Guide (NASA Technical Memorandum 86289) for reference to SIFT system commands, procedures and functions, and overall guidance in SIFT system programming

Pharmacological and non-pharmacological approaches to prevent hypertension-induced renal disease in the spontaneously hypertensive rate

Hypertension affects 50 million Americans and remains the second leading cause of renal failure in the United States. Current pharmacological and non-pharmacological approaches to treat hypertension have proven effective, but the complexities of the disease and its renal effects warrant the need for new treatments. The hypothesis of this dissertation was that pharmacological or non-pharmacological approaches to reducing inflammation and oxidative stress would prevent hypertension-induced renal injury in the spontaneously hypertensive rat (SHR). In the first study, we blocked the inflammatory transcription factor, nuclear factor-kappa B (NF-ĸB), with pyrrolidine dithiocarbamate in the SHR kidney. In treated SHR, blood pressure decreased, renal hemodynamics were preserved, and oxidative stress and inflammation were attenuated at both the cytosolic and mitochondrial levels; suggesting a role for NF-ĸB in potentiating hypertension-induced renal injury. In the second study, we examined the effects of aerobic exercise training on renal oxidative stress and inflammation. Exercised SHR exhibited normalized blood pressure and renal hemodynamics. These effects were attributed to lower NF-ĸB activity and decreased oxidative stress in the SHR kidney. In the third and fourth studies, we examined the effects of diet modification by use of blueberry-enriched diets, since blueberries have one of the highest antioxidant capacities of any fruit or vegetable tested to date. In the third study, we fed stroke-prone SHR high salt and a blueberry-enriched diet for 2 days, 6 weeks, or 12 weeks, and examined renal parameters. The SHR fed the blueberry diet for the 6- or 12-week periods demonstrated lower oxidative stress, lower blood pressure, and preservation of renal hemodynamics. These effects were likely due to a hormetic effect of the blueberries themselves, since rats fed blueberries for 2 days demonstrated higher oxidative stress. In the final study, we added blueberries to a stroke-permissive diet, which accelerates renal damage in SHR. Rats were fed diets for 10 weeks. Rats fed the control diet had severe hypertension, severe oxidative stress, and severe inflammation as evidenced by NF-ĸB activation, and exhibited signs of renal failure. Rats fed the blueberry supplemented diet exhibited decreases in blood pressure, oxidative stress, and inflammation, and also had preserved renal structure and function
