Representational Style and Congressional Elections: New York\u27s 19th District in the 115th Congress

The disconnect between members of Congress and the American public is no secret. Of the three branches of government, the legislative branch is intended to be the most representative of the people. However, it consistently faces the lowest approval ratings among the American public. Although the public largely disapproves of Congress as a legislative body, most Americans support their own representative. This phenomenon is reflected in high reelection rates for congressional incumbents. My thesis examines the relationship between congressional representation and elections through an evaluation of the representational style of Congressman John Faso. Faso, who represented New York’s 19th District in the 115th Congress, lost reelection after a single term. I assess the role of political communication in representational style through a qualitative interpretation of Faso’s press releases. I utilize press releases as a method for understanding representational style because Faso used this tool to explain positions and votes. Through an analysis of two politically-polarizing case studies, healthcare and tax reform, I determine that Congressman Faso lacked a cohesive representational style during the 115th Congress. Additionally, I conclude that Congressman Faso’s inconsistent representational style had electoral implications in a toss-up district

Molecular Studies of House Mice in Southern New Zealand

The house mouse, Mus Musculus, was first introduced into New Zealand in significant numbers in the mid nineteenth century. Earlier research suggests that multiple introductions of the three subspecies of house mouse M. m. domesticus, M. m. musculus and M. m. castaneus occurred at this time. While M. m. domesticus is widely distributed in New Zealand with M. m. musculus somewhat less so, the only extant evidence found to date for M. m. castaneus is in hybrid mice found principally in the southern half of the South Island. In this study, the hybrid population of mice in the South Island was examined in detail using a variety of molecular techniques. The extent of the hybrid zone was first established using a simple polymerase chain reaction (PCR) technique that enabled rapid identification of mitochondrial genomes as being M. m. domesticus, castaneus or musculus in nature. In the second part of the study, four representative mice from the hybrid zone and three M. m. domesticus from north of this zone were subjected to high density (600K) single nucleotide polymorphism (SNP) analyses in order to pinpoint regions of the genomes that differed in a significant manner between the two groups. In a refinement of these analyses, regions of each genome were identified as being domesticus-, castaneus- or musculus-like, using diagnostic SNP alleles for each sub-species. Some 170 mice, principally collected in the Southern South Island, were screened using the rapid PCR technique. In the coastal regions, all mice further south than 44oS had M. m. castaneus mtDNA whereas those north of 43oS had M. m. domesticus mtDNA. Between the two, there is a ‘contact zone’ in which both subspecies were found, sometimes in the same building. The contact zone extends approximately 50km north to south and some 30km inland. Classical tests with three nuclear DNA markers confirmed earlier work, namely, that the nuclear genomes of all mice appeared to be predominantly domesticus-like. Although there is no obvious geographical, ecological or land-use features that characterise this contact zone it may be relevant that there is the distinct change to a wetter colder climate in the south and inland of the contact zone, especially in winter. The inability to identify obvious defining features is not surprising, given that much research over many years worldwide has failed to yield an explanation for distinct mouse hybrid zones. The high density SNP analyses demonstrated that the nuclear genomes of all seven representative mice were very similar and largely (approximately 95%+) domesticus-like in nature. Despite this similarity, clusters of SNPs did reveal differences throughout the genome, often just extending over a few haplotype blocks and often encompassing much less than a million basepairs (Mb). Some of these were of biological interest, for example clusters of vomeronasal receptor genes and also genes believed to be involved in maternal-fetal conflict, which are known to vary markedly between species. The diagnostic SNP analyses confirmed that no marked differences exist between the genomes of the hybrid and M. m. domesticus mice. As stated above, the genomes were predominantly domesticus-like but small regions (~1Mb) of castaneus-like and musculus-like genome were found scattered throughout all mice but, contrary to initial expectations, there was no preponderance of castaneus-like regions in the hybrid mice. The one exception to the largely identical genomic SNP patterns, were those from the mouse collected in Hamilton. This was quite bizarre, in that its genome contains large (up to 10Mb) musculus-like regions that correspond exactly to the same regions in a common laboratory strain of mouse, C57BL/6J. I conclude that if pure M. m. castaneus mice did originally reach New Zealand, extensive ‘backcrossing’ with M. m. domesticus has virtually eliminated the castaneus genome, with just a few remnants remaining that may or may not confer some selective advantage, but could just as likely represent segregation of recognition factors that give rise to assortative mating. Thus, the most obvious and consistent genetic difference between the mice remains the original observation concerning their mitochondrial genomes and these should be examined in more detail. In future research aimed at identifying potential selective advantages that have allowed the hybrid mice to exclusively populate the southern South Island factors that relate to climate should be considered. Specifically, the fact that, in humans, some mitochondrial haplotypes are believed to confer a selective advantage in colder climates immediately suggests that examining variants of key genes involved in energy metabolism such as NADH-dehydrogenase-subunit-3 ( ND3 ) in the hybrid mice could be a profitable line of future research

The Forest Primeval of Indiana as Recorded in the Original U.S. Land Surveys and an Evaluation of Previous Interpretations of Indiana Vegatation

Between 1799 and 1846, the territory which now comprises the State of Indiana was divided by the United States public land survey into six-mile-square townships as a prerequisite for the equitable distribution of public lands. Each township, in turn, was subdivided into 36 sections one-mile square. Section and quarter-section corners, as well as a number of intermediate points, were marked by blazing trees. The location, name, and diameter of more than 214,500 witness trees, composed of more than 80 species and generic groups, were recorded in the Indiana surveyors\u27 journals. These journals and the maps compiled from them, records inscribed before a tidal wave of settlers swept away much of the natural vegetation of the State, represent our most tangible account of Indiana\u27s primeval forests. They are the source of data for this study

The AIM2 inflammasome is critical for innate immunity to Francisella tularensis.

Francisella tularensis, the causative agent of tularemia, infects host macrophages, which triggers production of the proinflammatory cytokines interleukin 1beta (IL-1beta) and IL-18. We elucidate here how host macrophages recognize F. tularensis and elicit this proinflammatory response. Using mice deficient in the DNA-sensing inflammasome component AIM2, we demonstrate here that AIM2 is required for sensing F. tularensis. AIM2-deficient mice were extremely susceptible to F. tularensis infection, with greater mortality and bacterial burden than that of wild-type mice. Caspase-1 activation, IL-1beta secretion and cell death were absent in Aim2(-/-) macrophages in response to F. tularensis infection or the presence of cytoplasmic DNA. Our study identifies AIM2 as a crucial sensor of F. tularensis infection and provides genetic proof of its critical role in host innate immunity to intracellular pathogens

Large-scale variations in ozone and polar stratospheric clouds measured with airborne lidar during formation of the 1987 ozone hole over Antarctica

A joint field experiment between NASA and NOAA was conducted during August to September 1987 to obtain in situ and remote measurements of key gases and aerosols from aircraft platforms during the formation of the ozone (O3) hole over Antarctica. The ER-2 (advanced U-2) and DC-8 aircraft from the NASA Ames Research Center were used in this field experiment. The NASA Langley Research Center's airborne differential absorption lidar (DIAL) system was operated from the DC-8 to obtain profiles of O3 and polar stratospheric clouds in the lower stratosphere during long-range flights over Antarctica from August 28 to September 29, 1987. The airborne DIAL system was configured to transmit simultaneously four laser wavelengths (301, 311, 622, and 1064 nm) above the DC-8 for DIAL measurements of O3 profiles between 11 to 20 km ASL (geometric altitude above sea level) and multiple wavelength aerosol backscatter measurements between 11 to 24 km ASL. A total of 13 DC-8 flights were made over Antarctica with 2 flights reaching the South Pole. Polar stratospheric clouds (PSC's) were detected in multiple thin layers in the 11 to 21 km ASL altitude range with each layer having a typical thickness of less than 1 km. Two types of PSC's were found based on aerosol backscattering ratios: predominantly water ice clouds (type 2) and clouds with scattering characteristics consistent with binary solid nitric acid/water clouds (type 1). Large-scale cross sections of O3 distributions were obtained. The data provides additional information about a potentially important transport mechanism that may influence the O3 budget inside the vortex. There is also some evidence that strong low pressure systems in the troposphere are associated with regions of lower stratospheric O3. This paper discusses the spatial and temporal variations of O3 inside and outside the polar vortex region during the development of the O3 hole and relates these data to other measurements obtained during this field experiment

Relationships among common illness symptoms and the protective effect of breastfeeding in early childhood in MAL-ED: An eight-country cohort study

Children in low-income countries experience multiple illness symptoms in early childhood. Breastfeeding is protective against diarrhea and respiratory infections, and these illnesses are thought to be risk factors of one another, but these relationships have not been explored simultaneously. In the eight-site MAL-ED study, 1,731 infants were enrolled near birth and followed for 2 years. We collected symptoms and diet information through twice-weekly household visits. Poisson regression was used to determine if recent illness history was associated with incidence of diarrhea or acute lower respiratory infections (ALRI), accounting for exclusive breastfeeding. Recent diarrhea was associated with higher risk of incident diarrhea after the first 6 months of life (relative risk [RR] 1.10, 95% confidence interval [CI] 1.04, 1.16) and with higher risk of incident ALRI in the 3- to 5-month period (RR 1.23, 95% CI 1.03, 1.47). Fever was a consistent risk factor for both diarrhea and ALRI. Exclusive breastfeeding 0-6 months was protective against diarrhea (0-2 months: RR 0.39, 95% CI 0.32, 0.49; 3-5 months: RR 0.83, 95% CI 0.75, 0.93) and ALRI (3-5 months: RR 0.81, 95% CI 0.68, 0.98). Children with recent illness who were exclusively breastfed were half as likely as those not exclusively breastfed to experience diarrhea in the first 3 months of life. Recent illness was associated with greater risk of new illness, causing illnesses to cluster within children, indicating that specific illness-prevention programs may have benefits for preventing other childhood illnesses. The results also underscore the importance of exclusive breastfeeding in the first 6 months of life for disease prevention
