For-Profit Education in the United States: A Primer
Higher education during the twentieth century underwent drastic changes as reformers forcefully argued education was the business of the state, and society could be improved by strong, publicly backed schools (Coulson 1999). Often proponents of state-sponsored education on the left argued the government should use education as a way to shape the minds of the nation's citizens, who were not responsible enough to take care of their own education properly (Coulson 1999). On the right, similar arguments were used as special interest groups saw the government as a means to influence what went on in the classroom. Consequently, the government stepped into the higher education arena, in part, by arguing people were not competent enough to oversee their own education. While the data for this period are scarce, it is safe to say for the period 1890 -- 1972, for-profit colleges were increasingly marginalized by the growth of highly subsidized public institutions (Breneman et al. 2006; Kinser 2006; Ruch 2001).Starting in the mid-1970s and accelerating through the 1980s and 1990s, for-profit education underwent a renaissance, due in large part to the 1972 reauthorization of the Higher Education Act, which increased the amount of government student aid available to for-profit schools (Kinser 2006; Turner 2006). During this era, the broadened scope of Pell Grants gave rise to an increasing number of for-profit universities offering associates, bachelors, and graduate degrees (Turner 2006). Since 1976, for-profit enrollment has grown at an annualized growth rate of about 11 percent, increasing by a factor of nearly twenty-three. For-profits'market share of higher education has gone from 0.4 percent to nearly 6 percent (U.S. Department of Education, National Center for Education Statistics, 2006a). The robust resurgence of for-profit schools suggests America's nonprofit colleges are failing to meet fully the people's needs. As a result, for-profits are stepping in to meet market demands their highly subsidized counterparts have chronically failed to satisfy. These recent and rapid developments have once again brought for-profit education national visibility

dissertationCognitive control mechanisms were examined through depletion and restoration manipulations common in self-regulation literature. In this within-subjects, double-blind placebo controlled experiment, 33 participants performed three blocks of a high-congruency version of the flanker task while their EEG signals were recorded. Cognitive fatigue was induced in participants by lengthy flanker blocks, and they received either glucose or a placebo so we could examine the effects of metabolic restoration. Overall, there was a main effect of cognitive fatigue on flanker accuracy and on error-related event related potentials (ERPs). Participants had more accurate responses in the third block of the flanker task when they drank glucose as compared to the placebo. Additionally, the error-related negativity (ERN) waveform increased in amplitude during the third block of the flanker task when participants drank glucose. These findings suggest that there is overlap between the bodies of literature on cognitive control and self-regulation, specifically when measuring the activity in the anterior cingulate cortex during conflict paradigms

thesisThe present study investigates individual differences in information processing following an error. Participants with high working memory capacity (WMC) and with low WMC performed a high congruency version of the flanker task under both speedand accuracy-stress. We recorded event-related potentials and behavioral measures of accuracy and response time (RT) in the flanker task with a primary focus on processing following an error. We compared WMC groups on the error related negativity (ERN) and the positivity following an error (Pe) associated with both task goal and working memory capacity. Those with a high WMC had a larger ERN compared to those with lower WMC. In addition, accuracy stress reflected a larger ERN than speed-based trials. The data suggest the error related negativity was modulated by task goals and working memory capacity. The Pe was modulated by task goals, but not by WMC. However, a significant interaction demonstrates an increased awareness of erroneous responses for high WMC subjects under accuracy-stress. Additionally, both groups exhibited greater posterror slowing under accuracy-stress as compared to speed-stress. This indicates that both WMC groups were able to adjust their behaviors according to the constraints of the task goals following an erroneous response
Outcomes Based Assessment of Universities
This study summarizes recent and continuing research conducted by the Center for College Affordability and Productivity (CCAP) on the metrics used for measuring college performance. Unlike other rankings, this study does not concentrate on the inputs of college education such as endowment size, number of faculty, or the educational preparation of students as measured by SAT scores, etc. Instead, it focuses on the outputs, namely the success of students after graduation. Using the names of entrants in Marquis Publishing's 2008 edition of Who's Who in America as our standard for measuring high levels of success, we collected the names of over 5,200 individuals, along with their educational background.This is more than a 5 percent sampling of all names listed in this standard reference work. From this sample, we then calculated which colleges produced the most successful graduates. The results thus far have been both fascinating and surprising.We have found that while going to top ranked schools as measured by standard college rankings does correlate with success, it is a weaker relationship than many may have previously believed. The study reveals that the "industry standard," U.S. News & World Report (USNWR) rankings, on the whole, is only weakly related to graduate success. This suggests that the characteristics contributing to the value of a student's education differ substantially from what is typically assumed. The goal of this study is not to serve as a definitive source for ranking and comparing colleges. Rather, the research presented herein will hopefully serve as both an impetus and road ma
Long-segment thoracoabdominal aortic occlusions in childhood
Developmental coarctation, hypoplasia, and occlusion of the abdominal aorta is a rare disease encompassing many differing etiologies and diverse methods of treatment. Long-segment thoracoabdominal aortic occlusion, an extreme manifestation of this disorder, has not previously been reported in children. Two pediatric patients with this entity, a 5- and 13-year-old with uncontrolled hypertension, underwent extensive arterial reconstructions for this entity and provided the impetus for this report. An ascending thoracic aorta to infrarenal aortic expanded polytetrafluoroethylene bypass was undertaken in the younger child. A distal thoracic aorto-bi-iliac artery expanded polytetrafluoroethylene bypass, with implantation of the left renal artery to one graft limb and a right renal artery bypass originating from the other limb, was performed in the older child. There were no major perioperative complications. Both patients were discharged with easily controlled blood pressures. They have remained normotensive at 13 and 14 months follow-up
Survey Evidence on Conditional Norm Enforcement
We discuss survey evidence on individuals' willingness to sanction norm violations - such as evading taxes, drunk driving, fare dodging, or skiving o work - by expressing disapproval or social exclusion. Our data suggest that people condition their sanctioning behavior on their belief about the frequency of norm violations. The more commonly a norm violation is believed to occur, the lower the individuals' inclination to punish it. Based on an instrumental variable approach, we demonstrate that this pattern reflects a causal relationship
Once and Future Gulf of Mexico Ecosystem: Restoration Recommendations of an Expert Working Group
The Deepwater Horizon (DWH) well blowout released more petroleum hydrocarbons into the marine environment than any previous U.S. oil spill (4.9 million barrels), fouling marine life, damaging deep sea and shoreline habitats and causing closures of economically valuable fisheries in the Gulf of Mexico. A suite of pollutants—liquid and gaseous petroleum compounds plus chemical dispersants—poured into ecosystems that had already been stressed by overfishing, development and global climate change. Beyond the direct effects that were captured in dramatic photographs of oiled birds in the media, it is likely that there are subtle, delayed, indirect and potentially synergistic impacts of these widely dispersed, highly bioavailable and toxic hydrocarbons and chemical dispersants on marine life from pelicans to salt marsh grasses and to deep-sea animals. As tragic as the DWH blowout was, it has stimulated public interest in protecting this economically, socially and environmentally critical region. The 2010 Mabus Report, commissioned by President Barack Obama and written by the secretary of the Navy, provides a blueprint for restoring the Gulf that is bold, visionary and strategic. It is clear that we need not only to repair the damage left behind by the oil but also to go well beyond that to restore the anthropogenically stressed and declining Gulf ecosystems to prosperity-sustaining levels of historic productivity. For this report, we assembled a team of leading scientists with expertise in coastal and marine ecosystems and with experience in their restoration to identify strategies and specific actions that will revitalize and sustain the Gulf coastal economy. Because the DWH spill intervened in ecosystems that are intimately interconnected and already under stress, and will remain stressed from global climate change, we argue that restoration of the Gulf must go beyond the traditional "in-place, in-kind" restoration approach that targets specific damaged habitats or species. A sustainable restoration of the Gulf of Mexico after DWH must: 1. Recognize that ecosystem resilience has been compromised by multiple human interventions predating the DWH spill; 2. Acknowledge that significant future environmental change is inevitable and must be factored into restoration plans and actions for them to be durable; 3. Treat the Gulf as a complex and interconnected network of ecosystems from shoreline to deep sea; and 4. Recognize that human and ecosystem productivity in the Gulf are interdependent, and that human needs from and effects on the Gulf must be integral to restoration planning. With these principles in mind, the authors provide the scientific basis for a sustainable restoration program along three themes: 1. Assess and repair damage from DWH and other stresses on the Gulf; 2. Protect existing habitats and populations; and 3. Integrate sustainable human use with ecological processes in the Gulf of Mexico. Under these themes, 15 historically informed, adaptive, ecosystem-based restoration actions are presented to recover Gulf resources and rebuild the resilience of its ecosystem. The vision that guides our recommendations fundamentally imbeds the restoration actions within the context of the changing environment so as to achieve resilience of resources, human communities and the economy into the indefinite future

Quality of Private Ground-Water Supplies in Kentucky
About 3.7 million people live in Kentucky, of which 1.9 million (52 percent) live in urban areas (roughly defined as any community with 2,500 or more people) and 1.8 million (48 percent) live in rural areas (University of Kentucky, 1993). Figure 1 summarizes sources of drinking water for Kentucky residents. About 70 percent of Kentuckians get their daily supply of water from surface-water sources - lakes and streams; about 25 percent get their water from ground-water wells; and about 5 percent get their water from other sources - springs, cisterns, ponds, or hauled water
