Effective Communication Of Standard Errors And Confidence Intervals, Thomas A. Louis, Scott L. Zeger

Johns Hopkins University, Dept. of Biostatistics Working Papers

We recommend a format for communicating an estimate with its standard error or confidence interval. The format reinforces that the associated variability is an inseparable component of the estimate and it substantially improves clarity in tabular displays.

Earth Sciences

It has been shown that sunlit snow and ice plays an important role in processing atmospheric species. Photochemical production of a variety of chemicals has recently been reported to occur in snow/ice and the release of these photochemically generated species may significantly impact the chemistry of the overlying atmosphere. Nitrogen oxide and oxidant precursor fluxes have been measured in a number of snow covered environments, where in some cases the emissions significantly impact the overlying boundary layer. For example, photochemical ozone production (such as that occurring in polluted mid-latitudes) of 3-4 ppbv/day has been observed at South Pole, due to …

Construction Of (Hierarchical) Identity-Based Encryption Protocols Using Bilinear Pairing., Sanjit Chatterjee Dr.

Doctoral Theses

Science, it is argued [65], advances through paradigm shifts. Concepts emerge that open-up new vistas of research, fundamentally changing the way we are used to looking at things. Between these paradigm shifts remain the periods of consolidation. Periods when human mind explores the newly found territory, shedding light on hitherto unknown dimensions. If radical changes are the hallmarks of paradigm shifts, the period within witnesses small but continuous developments, occasionally marked by its own milestones. It is in these periods that human faculty tries to grasp the full significance of the new concepts, consolidates its gains and thereby pushes the …

Short-Distance Contribution To The Spectrum Of Hawking Radiation, I. Agulló, J. Navarro-Salas, Gonzalo J. Olmo, Leonard Parker

Faculty Publications

The Hawking effect can be rederived in terms of two-point functions and in such a way that it makes it possible to estimate, within the conventional semiclassical theory, the contribution of ultrashort distances at I+ to the Planckian spectrum. The analysis shows that, for Schwarzschild astrophysical black holes, the Hawking radiation (for both bosons and fermions) is very robust up to very high frequencies (typically two orders above Hawking's temperature). Below this scale, the contribution of ultrashort distances to the spectrum is negligible. We argue, using a simple model with modified two-point functions, that the above result seems to have …

Comparative Analysis Of Environmental Kuznets Curve In Central And Eastern Europe And South And East Asia, Yu-Chin Pang

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Environmental deterioration has frequently been viewed as a problem that inevitably accompanies economic development and industrialization. However, different economic backgrounds might experience different kinds and levels of environmental deterioration. This study investigated environmental deterioration in two groups of countries with comparable income levels but different economic backgrounds-transitional Central and Eastern Europe (CEE) and non-transitional South and East Asian (SEA) countries.

This research utilized the environmental Kuznets curve (EKC) hypothesis to explain the relationships among macroeconomic indicators, country categories, and atmospheric concentrations in the CEE and SEA regions. Three research questions and six hypotheses and related sub-hypotheses were answered and tested …

Parasite Findings In Archeological Remains: Diagnosis And Interpretation, Adauto Arajuo, Karl J. Reinhard, Luiz Fernando Ferreira

School of Natural Resources: Faculty Publications

Paleoparasitology has contributed to resolving the debate about the peopling of the Americas and determining the antiquity of human parasite infection. Hookworm (Ancylostomidae) and whipworm (Trichuris trichiura) and other exclusive human intestinal parasites have been recorded in pre-Columbian America. These parasite species originated in pre-hominids and have accompanied humans across continents when people went out of Africa. However, for those human populations that crossed the Bering Land Bridge from Siberia to Alaska, cold climate conditions hampered parasite transmission. Alternative migration routes have been proposed to explain the presence of these parasites in pre-Columbian populations in the Americas. Other …

Improvement Of Retrieved Reflectance In The Presence Of Clouds, Brent Bartlett

Theses

Many algorithms exist to invert airborne imagery from units of either radiance or sensor specific digital counts to units of reflectance. These compensation algorithms remove unwanted atmospheric variability allowing objects on the ground to be analyzed. Low error levels in homogenous atmospheric conditions have been demonstrated. In many cases however, clouds are present in the atmosphere which introduce error into the inversion at unacceptable levels. For example, the relationship that is defined between sensor reaching radiance and ground reflectance in direct sunlight will not be the same as in a cloud shadow. A novel method has been developed which utilizes …

Surfactant Properties Of Atmospheric And Model Humic‐Like Substances (Hulis), Ilya Taraniuk, Ellen Graber, Alexander Kostinski, Yinon Rudich

Department of Physics Publications

Surface‐active organics such as humic‐like substances (HULIS) are abundant in aerosol particles and can lower the surface tension of cloud droplets forming on secondary organic and biomass burning aerosols. How fast is the diffusion of these species, relative to the time scale of cloud droplet growth? Here we report surface tension measurements of solutions containing HULIS extracted from smoke and pollution aerosol particles as well those of molecular weight‐fractionated aquatic fulvic acids. Diffusion coefficients are estimated based on the Gibbs adsorption isotherms. The results suggest that HULIS diffusion to the surface of forming droplets is typically more rapid than the …

Experts And Non-Experts, Irene Valsecchi

Fondazione Eni Enrico Mattei Working Papers

The paper is concerned with the interaction between two agents: an expert, announcing his probability that a particular state of the world will occur, and a non-expert decision-maker, who takes action according to his posterior beliefs. The decision-maker considers the expert an experiment of uncertain reliability and takes the received messages as the outcomes of such an experiment. The model of the expert in the decision-maker’s mind bears no relation with any measure of the expert’s actual information. The paper shows that messages will be biased, notwithstanding solidarity between the agents. However, the longer the interaction, the less severe will …

Significance Of Trends Toward Earlier Snowmelt Runoff, Columbia And Missouri Basin Headwaters, Western United States, Johnnie N. Moore, Joel T. Harper, Mark C. Greenwood

Geosciences Faculty Publications

We assess changes in runoff timing over the last 55 years at 21 gages unaffected by human influences, in the headwaters of the Columbia-Missouri Rivers. Linear regression models and tests for significance that control for ‘‘false discoveries’’ of many tests, combined with a conceptual runoff response model, were used to examine the detailed structure of spring runoff timing. We conclude that only about one third of the gages exhibit significant trends with time but over half of the gages tested show significant relationships with discharge. Therefore, runoff timing is more significantly correlated with annual discharge than with time. This result …

Development Of A New Ca Ii H And K Spectrophotometric Temperature Index, Kathleen Elizabeth Moncrieff

Theses and Dissertations

We are developing a new spectrophotometric temperature index based on the Ca II H and K lines. Because these lines are present even in very cool stars and because the Ca II H line is blended with the H-epsilon line in hot stars, this index should cover a very broad range of spectral types. Our data set consisted of 95 stars with spectral types ranging from O9 to M1. We examined five different indices based on the Ca II H + H-epsilon and K lines, as well as single-wavelength indices centered on each of the H-delta and H-gamma lines, which …

Game-Theoretic View On Intermediated Exchange, Thomas Grassl

Dissertations, Master's Theses and Master's Reports - Open

Intermediaries permeate modern economic exchange. Most classical models on intermediated exchange are driven by information asymmetry and inventory management. These two factors are of reduced significance in modern economies. This makes it necessary to develop models that correspond more closely to modern financial marketplaces. The goal of this dissertation is to propose and examine such models in a game theoretical context.

The proposed models are driven by asymmetries in the goals of different market participants. Hedging pressure as one of the most critical aspects in the behavior of commercial entities plays a crucial role.

The first market model shows that …

A Typology And Discourse Analysis Of The Status And Appointments Of Librarians At Land Grant Universities, Mary K. Bolin

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study examined the status of librarians at land grant universities in each state (n=50). University websites were the source of data on librarians’ employee group (faculty/staff), administrator title, rank system, tenure eligibility, and faculty senate representation. The data were analyzed to find frequencies and cross tabulations. The findings indicate four status types in the population: Professorial (n=21); Other ranks with tenure (n=14); Other ranks without tenure (n=5); Academic or professional staff (n=10). Eighty percent of the institutions in the population have librarians who are faculty (n=40), and 85% of …

Assessment At The Program Level: Using Assessment To Improve Undergraduate Statistics Programs, Roxy Peck, Beth Chance

Office of the Dean (COSAM) Scholarship

With the growing focus on assessment and accountability, programs at many universities are now expected to define learning goals and objectives at the program level (as opposed to the course level) and to devise strategies for assessing whether these goals and objectives are being met. This paper will look at the role of assessment at the program level and how the resulting information about student learning can be used to make informed decisions about curriculum.

A System Approach To Integrated Power Amplifier Analysis And Design, Vladimir I. Prodanov, Mihai Banu

Electrical Engineering

Numerous power amplifier circuits are described in the literature, which seem to follow many distinct design approaches. While circuit implementations may be quite different indeed, the underlining system-level signaling inside these circuits follows similar conditions dictated by the common design objective for high efficiency. This paper presents a general theory for analyzing and designing power amplifiers, providing an insight on the fundamental factors limiting the performance, irrespective of the implementation circuits or technology.

The 14N Quadrupole Coupling In Hexamethylene Triperoxide Diamine (Hmtd), John Persons, Gerard S. Harbison

Gerard S. Harbison Publications

Using high-field NMR, we have determined the magnitude of the nuclear quadrupole interaction in hexamethylene triperoxide diamine (HMTD), the explosive allegedly used in the London bombings of July 2005. The experimental quadrupolar coupling constant, 5.334 MHz, is in good agreement with quantum chemical calculations. The predicted single zero-field transition frequency should lie in a relatively empty part of the 14N nuclear quadrupole resonance (NQR) spectrum; the spin relaxation rate is reasonably fast.

Testing The Assumption Of Sample Invariance Of Item Difficulty Parameters In The Rasch Rating Scale Model, Joseph A. Curtin

Theses and Dissertations

Rasch is a mathematical model that allows researchers to compare data that measure a unidimensional trait or ability (Bond & Fox, 2007). When data fit the Rasch model, it is mathematically proven that the item difficulty estimates are independent of the sample of respondents. The purpose of this study was to test the robustness of the Rasch model with regards to its ability to maintain invariant item difficulty estimates when real (data that does not perfectly fit the Rasch model), polytomous scored data is used. The data used in this study comes from a university alumni questionnaire that was collected …
