Henry Hardin Cherry: The Early Period of a Life\u27s Work

The first fifty years of Henry Hardin Cherry show a very formative period of his life. Born in 1864, Cherry left his family farm at the age of 21 to pursue his own education and by 1892 become head of a school in Bowling Green that was in trouble financially and and also had a shrinking enrollment. He began the transformation of this school and it became his life\u27s work. This work included keeping the Southern Normal School afloat in its assorted difficulties, getting the school installed as a state-supported normal school and gaining adequate funding from the state to ensure its continuance and the placement of a new campus. Leading the school itself had many challenges. Cherry\u27s leadership with administration, faculty and students showed his fervor for the favorable completion of his work. Family and friends were important as well and, even though he spent a good deal of time working on behalf of his school, he had many cherished relationships in this time period. His character shone through in all of this as a man who held his passions confidently, worked with a strong ethic and drove his visionary ability to a high, yet practical standard

How the size of a city’s immigrant population influences feelings of trust and safety in urban Europe

Does immigration affect the way that residents of a city perceive their social environment? Drawing on new research, Kevin T. Smiley and Yulin Yang explain that the size of the immigrant population in a city has an impact on feelings of trust and safety among residents, but this effect depends crucially on the population size of the city

Massive investments in bike infrastructure have got more people moving in Memphis, but they have also affected social inequality

In the past six years Memphis, Tennessee has undergone a cycling revolution, creating more than 100 miles of bicycle lanes and greenways. Despite the beneficial environmental implications of such a scheme, is bike oriented development just a way of reinforcing the status quo of social inequality? Kevin T. Smiley, Wanda Rushing, and Michele Scott find that while such bike schemes are likely to spur economic development and raise property values, these economic benefits are most likely to go to developers and may result in further racialized gentrification

Industrial Pollution and Civic Capacity in Metropolitan America

Environmental justice research analyzes inequalities by race and class in exposure to unhealthful toxins in the air, land, and water. These inequalities are typically considered at relatively small scales, such as neighborhoods, because these scales most effectively correspond to the area of exposure. This important focus on neighborhoods, though, is paralleled by a growing research agenda on disparities and patterns at larger scales, such as metropolitan areas, that are theorized to affect exposure to toxins at lower scales. This dissertation investigates disparities in exposure to industrial pollution across metropolitan areas. The emergent research on the topic has not particularly identified mechanisms or processes that contribute to disparities across urban areas at the same time that wide variations have been described. To fill this research gap, I turn to a framework that centers on civic capacity to analyze how and why these disparities have emerged. The analysis is conducted using the Risk-Screening Environmental Indicators Geographic Microdata (RSEI-GM), which uses fine-grained air pollution data that takes into account the toxicity of chemicals from more than 20,000 facilities in the United States, and how these data correspond to risks to human health. The findings suggest the utility of a civic capacity framework in three primary findings. First, I explicate how different measures of social capital organizations, which are based on the bridging or bonding nature of social ties, are correlated with levels of exposure to unhealthful toxins from industrial polluters. Second, I dive further into a discussion of social capital organizations by examining religious congregations, and finding that greater numbers of congregations are associated with accentuated or attenuated racial inequalities in exposure depending on the type of religious congregation under examination. Third, I find that the changing manufacturing base of a metropolitan area is associated with industrial pollution such that urban areas that have lost manufacturing jobs from 1970 to 2010 are particularly disadvantaged in exposure to unhealthful toxins. Taken together, these findings argue that civic capacity underwrites capacities for social justice, including environmental justice, in metropolitan areas in the United States

A Meta-Analysis of Driving Performance and Crash Risk Associated with the Use of Cellular Telephones While Driving

This paper addresses the effects of cell phones on driving by means of a review of the literature and an analysis of scientifically credible epidemiological and driver performance studies. A total of 84 articles were obtained covering the period from 1969 to 2004. Sixty-eight articles were research papers measuring driving performance while using a cell phone and 16 articles were epidemiological studies that examined cell phone usage and their relationship to vehicular crashes. Epidemiological findings consistently showed an increase in crashes associated with use of cell phones. However, these studies did not control for exposure to cell phone use or to driving. The negative impact of cell phone usage is larger for responses to critical events than for vehicular control. Drivers responded about a quarter of a second later to stimuli in the presence of a cell phone distractor for all studies that were analyzed. Hands-free cell phones produced similar performance decrements to hand-held phones

Fibers and global geometry of functions

Since the seminal work of Ambrosetti and Prodi, the study of global folds was enriched by geometric concepts and extensions accomodating new examples. We present the advantages of considering fibers, a construction dating to Berger and Podolak's view of the original theorem. A description of folds in terms of properties of fibers gives new perspective to the usual hypotheses in the subject. The text is intended as a guide, outlining arguments and stating results which will be detailed elsewhere
