Improving Curve Number Runoff Estimates Using Dual Hydrologic Soil Classification and Potential Contributing Source Areas Delineation Methods  [PDF]
Katherine Miller, Katherine Folk Clancy
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.91003
Abstract: Runoff models such as the Curve Number (CN) model are dependent upon land use and soil type within the watershed or contributing area. In regions with internal drainage (e.g. wetlands) watershed delineation methods that fill sinks can result in inaccurate contributing areas and estimations of runoff from models such as the CN model. Two methods to account for this inaccuracy have been 1) to adjust the initial abstraction value within the CN model; or 2) to improve the watershed delineation in order to better account for internal drainage. We used a combined approach of examining the watershed delineation, and refining the CN model by the incorporating of dual hydrologic soil classifications. For eighteen watersheds within Wisconsin, we compared the CN model results of three watershed delineation methods to USGS gaged values. We found that for large precipitation events (>100 mm) the CN model estimations are closer to observed values for watershed delineations that identify the directly connected watershed and use the undrained hydrologic soil classification.
The Course of Well-Being in Romantic Relationships: Predicting Positive Affect in Dating Participants  [PDF]
Katherine J. Bao
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A161
Abstract:

People use different methods to make themselves happier, but their attempts at lasting happiness are often thwarted by the hedonic adaptation process. We examined changes in well-being over 8 weeks in participants who were involved in romantic relationships and those who were not. On average, both groups declined in well-being over time, but the relationship group experienced more positive emotions overall. High positive affect was predicted by higher aspirations, higher passionate love, and being in a same-ethnicity relationship. None of the variables we measured significantly predicted changes in positive affect over time, which may be due to the short duration of the study.

Linking Watershed Scales through Altered Waterways  [PDF]
Mason Johnson, Katherine Clancy
Journal of Water Resource and Protection (JWARP) , 2016, DOI: 10.4236/jwarp.2016.810073
Abstract: Nested hierarchy theory advances the idea that rivers have a fractal dimension where processes at the catchment scale (>1 km) control processes at the reach or mesoscale (100 m) and microscale (1 - 10 m). Largely absent from this work is a mesoscale link to the larger and smaller scales. We used stream alteration classifications to provide this link. We used orthophotographs, land cover, and LiDAR derived terrain models to classify stream alterations within four watersheds. We compared phosphorus point data with watershed, sub-watershed, and 100-meter buffers around the point data. In the predominately urban watershed, the 100 m buffer scale correlated better with phosphorus levels. In the predominately agricultural watershed, the sub-watershed scale correlated with phosphorus levels better. We found adding the classification of the stream alteration type clarified anomalously low phosphorus levels.
Comparison of Three Delineation Methods Using the Curve Number Method to Model Runoff  [PDF]
William D. Troolin, Katherine Clancy
Journal of Water Resource and Protection (JWARP) , 2016, DOI: 10.4236/jwarp.2016.811077
Abstract: Digital Elevation Models (DEMs) are spatial grids which are used to automate watershed boundary determination. Sinks are present within most DEMs. In order to easily process the watershed boundary, the sinks are reassigned to elevation equivalent to an adjacent cell. The derived DEM is called a “filled” DEM. Due to its relative simplicity, the use of the “filled” DEM is one of the most widely used methods to delineate watershed boundaries and works well in about 70 percent of the watersheds in the US. In landscapes with internal drainage, sinks may accurately represent these depressions. In this study, we compare two delineation methods that do not fill in sinks to another method that does fill in sinks. We examined ten gaged watersheds in Wisconsin and Minnesota. We found the spatial extent of the watersheds from the three methods were significantly different. To evaluate the delineation methods, we modeled ten runoff events using the Curve Number (CN) method and compared them to USGS gage discharge for each watershed. For small storms we found that there were no significant differences in the modeled runoff for three delineation methods. For large storms, we found the no-fill methods had a smaller error, but overall the difference was insignificant. This research suggests that capturing internal drainage by the delineation does not have much of an impact on the widely used CN model.
Da Comiss?o ao Conselho: a Organiza??o das Na??es Unidas conseguiu ou n?o criar um organismo de direitos humanos confiável?
Short, Katherine;
Sur. Revista Internacional de Direitos Humanos , 2008, DOI: 10.1590/S1806-64452008000200008
Abstract: in 2006 the united nations underwent its greatest reform since its foundation in 1945, showing a renewed commitment to human rights protection. the replacement of the commission on human rights with the human rights council signifies the growing strength of the international human rights regime. however, this change has not been without criticism. in particular it has been alleged that the council suffers from various political biases to the detriment of its effectiveness: for example, disproportionately focusing on the occupied palestinian territories while failing to swiftly respond to abuses in darfur. further, the council is arguably undermined by both its failure to implement effective mechanisms to prevent its own membership consisting to include acknowledged human rights violator and its continuing inability to harness us support. this paper analyses such criticisms.
Beyond Reference and Designation: On Interactive Implications of the Pronoun I in English
Katherine Hrisonopulo
Lodz Papers in Pragmatics , 2008, DOI: 10.2478/v10016-008-0006-2
Abstract: Using English-language material the paper aims to elaborate a theoretical model for the study of personal pronouns which could account for those uses of pronouns that go beyond their typical deictic (or referential) function of indicating speech-event participants. The proposed analysis focuses on the following two usage types of the pronoun I: (1) I say, there are lots of places to see there; (2) I tell you, John is the one to rely on. It is argued that despite idiomatic boundedness of the pronoun I in the expressions I say and I tell you the pronoun does contribute to the pragmatic effects of the utterances in (1) and (2), namely, the effects of attention seeking and persuasion respectively. It is assumed that these effects could be attributed to interactive implications of the pronoun I that typically emerge in situations of dialogic discourse. To account for interactive orientedness of the first-person pronoun the paper puts forward two interrelated hypotheses. First, it is supposed that the first-person pronoun functions as a sign which is indexed to four regular contexts: referential context, perceptual context, the context of the speaker's subjective experiences, the context of interaction. Second, it is hypothesized that interactive implications of the pronoun I are introduced into oral discourse due to the interplay of two or more of the postulated contexts. Both hypotheses are further substantiated with reference to examples of oral discourse drawn from English-language fiction.
Review of Observational Evidence for Dark Matter in the Universe and in upcoming searches for Dark Stars
Freese, Katherine
High Energy Physics - Phenomenology , 2008,
Abstract: Over the past decade, a consensus picture has emerged in which roughly a quarter of the universe consists of dark matter. The observational evidence for the existence of dark matter is reviewed: rotation curves of galaxies, weak lensing measurements, hot gas in clusters, primordial nucleosynthesis and microwave background experiments. In addition, a new line of research on Dark Stars is presented, which suggests that the first stars to exist in the universe were powered by dark matter heating rather than by fusion: the observational possibilities of discovering dark matter in this way are discussed.
Novel Fractal Antenna Arrays for Satellite Networks: Circular Ring Sierpinski Carpet Arrays Optimized by Genetic Algorithms
Katherine Siakavara
PIER , 2010, DOI: 10.2528/PIER10020110
Abstract: A novel fractal antenna-array type is proposed. The design is based on the Sierpinski rectangular carpet concept. However, the generator is a circular ring area, filled with radiating elements, so the higher stages of the fractal development produce large arrays of circular rings which, besides the high directivity, have the advantage of the almost uniform azimuthal radiation pattern, attribute that many applications require. The introduced arrays can operate as direct radiating multi-beam phased arrays and meet the requirements of satellite communications links: high End of Coverage (EOC) directivity, low Side Lobe Level (SLL) and high Career to Interference ratio (C/I). These operational indices were further optimized by a synthesized multi-objective and multi-dimensional Genetic Algorithm (GA) which, additionally, gave arrays no more than 120 elements.
Paul Signac's Decorative Propaganda of the 1890s
Brion, Katherine
RIHA Journal , 2012,
Abstract: In the 1890s the political and artistic ambitions of the neo-impressionist artist Paul Signac were embodied by a series of decorative projects. This article contends that Signac, inspired by anarcho-communist discourse and the prospect of revolution, attempted to synthesize in these works the didactic logic of propaganda and "purely aesthetic emotion." This synthesis was epitomized by the explicit deployment of two systems, divisionism and decorative pattern. With these systems, Signac hoped to initiate contemporary viewers into the aesthetic and social harmony of an anarcho-communist future. In the interest of addressing larger audiences, particularly among workers, he imagined proletarian spaces for his work. But the didactic elements of Signac's painting met with critical resistance, and public sites he envisioned never materialized. Faced with this lack of recognition, and with a diminished revolutionary outlook in the wake of the Procès des Trente, Signac focused his painting on atemporal landscapes. This trajectory has been read as one of aesthetic liberation; this article seeks to retrieve the extent to which it was also one of constraint, tied to the frustration of Signac's political aspirations.
Science Translational Medicine – improving human health care worldwide by providing an interdisciplinary forum for idea exchange between basic scientists and clinical research practitioners
Forsythe, Katherine
GMS Medizin-Bibliothek-Information , 2010,
Abstract: Science Translational Medicine’s mission is to improve human health care worldwide by providing a forum for communication and interdisciplinary idea exchange between basic scientists and clinical research practitioners from all relevant established and emerging disciplines. The weekly journal debuted in October 2009 and is published by the American Association for the Advancement of Science (AAAS), the publisher of Science and Science Signaling. The journal features peer-reviewed research articles, perspectives and commentary, and is guided by an international Advisory Board, led by Chief Scientific Adviser, Elias A. Zerhouni, M.D., former Director of the National Institutes of Health, and Senior Scientific Adviser, Elazer R. Edelman, M.D., Ph.D., Thomas D. and Virginia W. Cabot Professor of Health Sciences and Technology, Massachusetts Institute of Technology. The Science Translational Medicine editorial team is led by Katrina L. Kelner, Ph.D., AAAS. A profound transition is required for the science of translational medicine. Despite 50 years of advances in our fundamental understanding of human biology and the emergence of powerful new technologies, the rapid transformation of this knowledge into effective health measures is not keeping pace with the challenges of global health care. Creative experimental approaches, novel technologies, and new ways of conducting scientific explorations at the interface of established and emerging disciplines are now required to an unprecedented degree if real progress is to be made. To aid in this reinvention, Science and AAAS have created a new interdisciplinary journal, Science Translational Medicine. The following interview exemplefies the pioneering content found in Science Translational Medicine. It is an excerpt from a Podcast interview with Dr. Samuel Broder, former director of the National Cancer Institute and current Chief Medical Officer at Celera. The Podcast was produced in tangent with Dr. Broder’s Research Perspective “Twenty-Five Years of Translational Medicine in Antiretroviral Therapy: Promises to Keep”, published in Science Translational Medicine, 7 July 2010; Volume 2, Issue 39. Dr. Broder’s perspective marks the 25th anniversary of modern antiretroviral drug discovery and development. In the early 1980s, Dr. Broder’s research team adapted the nucleotide analog AZT for treating HIV infection, thus ushering in the era of antiretroviral therapies that have enabled HIV-positive individuals to live longer. The Podcast interview was conducted by Annalisa VanHook, Associate Online Editor, AAAS.
