Lifting endomorphisms to automorphisms

Normal endomorphisms of von Neumann algebras need not be extendable to automorphisms of a larger von Neumann algebra, but they always have asymptotic lifts. We describe the structure of endomorphisms and their asymptotic lifts in some detail, and apply those results to complete the identification of asymptotic lifts of unital completely positive linear maps on von Neumann algebras in terms of their minimal dilations to endomorphisms.Comment: 7 pages, minor clarification of the introduction, new referenc

Built environment auditing, active mobility and children’s wellbeing

This thesis explores how planners can facilitate children’s wellbeing through auditing the urban environment for active travel. The findings reveal that audits have the potential to address critical issues regarding the quality of the built environment around schools. Further, children were found to be effective evaluators of their school environment. Auditing can be improved by highlighting the sensory qualities of the built environment and using audits strategically to adapt to the policy context of school environments

Say No to the Liberal Media: Conservatives and Criticism of the News Media in the 1970s

Thesis (Ph.D.) - Indiana University, Journalism, 2013"Say No to the Liberal Media: Conservatives and Criticism of the News Media in the 1970s" examines the significance of news media criticism among conservative opponents of liberalism in the 1970s. Critiques of the mainstream news media were levied by a wide array of conservatives of the 1970s, ranging from Republican party centrists to the racist and anti-Semitic Far Right. Conservatives criticized a wide range of news media organizations, including the three TV news networks; nationally influential publications such as the New York Times, Washington Post, Time, and Newsweek; and local newspapers such as the Boston Globe, Louisville Courier-Journal, and Detroit Free Press. Criticism of the news media was often motivated by anticommunist ideology, class-based resentments of liberal elites, and racially motivated opposition to civil rights. I demonstrate that criticism of the local news media was vital to grassroots conservative movements of the 1970s, particularly in movements against court-ordered busing for school integration in cities such as Boston, Louisville, and Detroit. I also show that criticism of the news media was an integral component of the antiliberal activism of conservatives including white supremacist members of the Citizens' Councils of America, opponents of feminism and the Equal Rights Amendment, Christian anticommunists of the 1970s, and anti-Semites who argued that the "Jewish news media" were active participants in a communist conspiracy. "Say No to the Liberal Media" also demonstrates that a thriving network of conservative publications was active during the 1970s. Such publications were crucial in disseminating the idea of liberal news media bias, and they often positioned themselves as pro-American, anticommunist truth-telling alternatives to the allegedly distorted and biased news provided by major newspapers and magazines and the three television news networks

Genotypic variability and inheritance of iron and zinc in sweetpotato

Sweetpotato [Ipomœa batatas (L.) Lam.] is a major subsistence crop in Sub-Saharan Africa, where iron and zinc deficiency in humans is an important health problem. A sweetpotato cultivar suited for subsistence farming, with high iron and zinc concentration, would be important in alleviating these deficiencies. The main objective of this research was to identify the extent of genetic variability of iron and zinc concentration in sweetpotato germplasm. An important subcomponent of this research was to determine the heritability of iron and zinc in sweetpotato. Protocol development studies were also conducted to aid in determining proper sampling technique. The results of the protocol development study indicated there was a significant replication effect between plot replicates but that no significant variation existed among roots from a plant, among plants from a given replicate plot, or among different root zones. In general, most of the genetic variability present was attributable to the difference in genotype. Therefore, one root from each replicate is sufficient for determining iron and zinc concentration in sweetpotato. A three-fold difference between high- and low-yielding cultivars for iron and zinc for ~80 cultivars was observed. The cultivars with the highest iron concentration were \u27Kyukei No. 63\u27 and \u27Pata de Oso\u27, both with ~7 ppm iron, fwb, from Japan and Peru, respectively. This compares with cultivars \u27Pung-mi\u27 and \u27Chuquimanco\u27 from Korea and Peru, respectively, both with ~3 ppm iron, fwb. These results suggest that sweetpotato with the highest levels of iron and zinc could provide about 30% and 15% of the daily dietary intact of these micronutrients, respectively. This is based on daily consumption of one 300-gram root. Iron and zinc in sweetpotato is highly available to humans given low phytic acid and high ascorbic acid concentration in orange flesh varieties. The heritability study showed high broad-sense heritability for iron (H2 = 0.74), zinc (H2 = 0.82), and dry matter concentration (H2 = 0.93) among half-sib families. These results and those which showed a positive correlation between iron and zinc concentration suggest that traditional breeding strategies like mass selection could improve the nutritional value of sweetpotato
