Investigating The Hispanic/Latino Male Dropout Phenomenon: Using Logistic Regression And Survival Analysis, Dorian Charles Vizcain

USF Tampa Graduate Theses and Dissertations

This dissertation explored the factors associated with dropping out of middle school and high school among Hispanic/Latino male students. Predictor variables investigated were: age, home language, retention history, SES, program of studies, suspensions, and GPA. Data were from a large urban school district in the state of Florida. A sample of 865 Hispanic/Latino male Latino students in the 8th grade in 1995-96 was followed longitudinally every year to the year 2000-01. Survival analysis and logistic regression were used to examine the data.

The research questions were: 1) What is the relation between age, home language, retention history, SES, program of …

Use Of Cross-Connect Clusters To Optimize Routing In Stm-64-Based Sdh Optical Network Systems, Bret William Durrett

Regis University Student Publications (comprehensive collection)

With the migration to Synchronous Digital Hierarchy, which uses the concept of logical rings, for backbone transmission systems, one of the major concerns that has been brought up repeatedly is a method in which to bring sub-rate circuits from one ring to another without having to decompose the entire backbone data stream to its individual circuits. This is critically important since the backbone data rate can be as high as 10 Gigabits per second or greater and may carry several thousand circuits, ranging in data rate from less than 2.4 Kilobits per second to 2.5 Gbps (STM-16). One potential means …

Tunnel Geology As Seen By Geologists: Manhattan, New York City, Nazrul I. Khandaker, Stanley Schleifer, Masud Ahmed, Alan R. Slaughter, Belal A. Sayeed, Dorean J. Flores, Mario Jo-Ramirez

Publications and Research

Current exploratory boring operations in and around Manhattan, New York City are providing geologists and geotechnical engineers with a plethora of new and interesting geological information, which has not been previously reported. The rocks encountered, mostly medium to high-grade metamorphic rocks, with both mafic and felsic intrusives, are highly variable in competency and mechanical durability. One of the most frequently encountered rock types is a garnetiferous-muscovite-biotite schist which grades into schistose gneiss and displays a wide variety of structural, compositional, and textural attributes. Metamorphic minerals showing the variable degree of metamorphism include graphite, talc, garnet, kyanite, tourmaline, emory, and occasionally …

Direct Enumeration Of Alloy Configurations For Electronic Structural Properties, Gus L. W. Hart, Peter A. Graf, Kwiseon Kim, Wesley B. Jones

Faculty Publications

We present and apply an approach to directly enumerate the band gaps and effective masses of all possible zinc blende-based alloy configurations whose unit cell contains up to a specified number of atoms. This method allows us to map the space of band gaps and effective masses versus alloy composition and atomic configuration. We demonstrate that a large number of band gaps and effective masses are available. We also discuss convergence of the method with respect to unit cell size and the combined optimization of band gap and effective mass for AlGaAs and GaInP semiconductor alloys.

A Visual Method For Indexing Muskrat Populations, Richard M. Engeman, Desley A. Whisson

United States Department of Agriculture Wildlife Services: Staff Publications

The native range for muskrats (Ondatru zibethicus) includes much of North America, but they also have been introduced beyond their native range, including into the Fall River, California, where they have come into conflict with human interests. An easily applied method to assess their abundance is an important need for their management. We developed a muskrat visual index (MVI) to provide the information necessary to address this need. Observations were made at randomly located sites along the river. The number of muskrats observed during a 45 min period was recorded during the late afternoon peak activity time at each …

Physics

Cuoricino is a taking data bolometric experiment searching for neutrinoless double beta decay (0νDBD) of ¹³⁰Te. The detector consists of an array of large cubic TeO₂ crystal bolometers. Cuoricino works at about 10 mK in the Gran Sasso Underground Laboratory. Good energy resolutions were obtained (2.1 keV at 911 keV and 3.9 keV at 2615 keV at best). The counting rate in the region of 0νDBD is 0.18±0.02 c/keV/kg/y. The limit for the 0νDBD half lifetime is 2.0 × 10²⁴ years at the 90% of C.L. This results correspond to a limit for the effective neutrino mass …

Neural Networks To Intrusion Detection, Dmitry V. Novikov

Theses

Recent research indicates a lot of attempts to create an Intrusion Detection System that is capable of learning and recognizing attacks it faces for the first time. Benchmark datasets were created by the MIT Lincoln Lab and by the International Knowledge Discovery and Data Mining group (KDD). A few competitions were held and many systems developed. The overall preference was given to Expert Systems that were based on Decision Making Tree algorithms. This work is devoted to the problem of Neural Networks as means of Intrusion Detection. After multiple techniques and methodologies are investigated, we show that properly trained Neural …

Semiclassical States, Effective Dynamics, And Classical Emergence In Loop Quantum Cosmology, Parampreet Singh, Kevin Vandersloot

Faculty Publications

We construct physical semiclassical states annihilated by the Hamiltonian constraint operator in the framework of loop quantum cosmology as a method of systematically determining the regime and validity of the semiclassical limit of the quantum theory. Our results indicate that the evolution can be effectively described using continuous classical equations of motion with nonperturbative corrections down to near the Planck scale below which the Universe can only be described by the discrete quantum constraint. These results, for the first time, provide concrete evidence of the emergence of classicality in loop quantum cosmology and also clearly demarcate the domain of validity …

Potential Of Modis Evi And Surface Temperature For Directly Estimating Per-Pixel Ecosystem C Fluxes, Abdullah Rahman, Daniel A. Sims, Vicente D. Cordova, Bassil Z. El-Masri

School of Earth, Environmental, & Marine Sciences Faculty Publications

We tested the potential of estimating per-pixel gross primary production (GPP) directly from the MODIS enhanced vegetation index (EVI) and respiration directly from MODIS surface temperature (MOD11). Carbon flux data were obtained from 10 eddy covariance tower sites representing a wide range of North American vegetations. The correlation between across-site tower GPP and EVI was comparable (r = 0.77) to that between tower GPP and MOD17-GPP (r = 0.73), suggesting that EVI could be used to provide reasonably accurate direct estimates of GPP on a truly per-pixel basis. There was also a strong relationship (r2 = 0.67) between respiration and …

Properties Model For Aqueous Sodium Chloride Solutions Near The Critical Point Of Water, Bing Liu

Theses and Dissertations

Traditional excess Gibbs energy models in terms of temperature, pressure, and concentration become progressively less effective in describing the thermodynamics of aqueous solutions at temperatures above 300 ¢ªC, and are totally inadequate in the critical region of water. This deficiency is due to the strong ion association and the large property fluctuations (such as density) with small variations in pressure, temperature, and solute concentration around the critical point of water. In this work, a speciation-based model has been developed to describe the thermodynamic properties of aqueous sodium chloride solutions in the critical region of water. The anomalous fluctuation problem is …

Big Cwatsets And Hamming Code, Matthew Davis, Thomas M. Langley, Norah Mazel

Mathematical Sciences Technical Reports (MSTR)

In contrast to Lagrange's Theorem in Finite Group Theory, we show that the ratio of the largest proper cwatset of degree d to the size of binary d-space approaches 1 as d approaches infinity. We show how to explicitly construct large cwatsets as cosets of Hamming Codes, and discuss many open questions that arise.

Population Intervention Models In Causal Inference, Alan E. Hubbard, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

Marginal structural models (MSM) provide a powerful tool for estimating the causal effect of a] treatment variable or risk variable on the distribution of a disease in a population. These models, as originally introduced by Robins (e.g., Robins (2000a), Robins (2000b), van der Laan and Robins (2002)), model the marginal distributions of treatment-specific counterfactual outcomes, possibly conditional on a subset of the baseline covariates, and its dependence on treatment. Marginal structural models are particularly useful in the context of longitudinal data structures, in which each subject's treatment and covariate history are measured over time, and an outcome is recorded at …

Additive Hazards Models With Latent Treatment Effectiveness Lag Time, Ying Qing Chen, Charles A. Rohde, Mei-Cheng Wang

Johns Hopkins University, Dept. of Biostatistics Working Papers

In many clinical trials to evaluate treatment efficacy, it is believed that there may exist latent treatment effectiveness lag times after which medical procedure or chemical compound would be in full effect. In this article, semiparametric regression models are proposed and studied to estimate the treatment effect accounting for such latent lag times. The new models take advantage of the invariance property of the additive hazards model in marginalizing over random effects, so parameters in the models are easy to be estimated and interpreted, while the flexibility without specifying baseline hazard function is kept. Monte Carlo simulation studies demonstrate the …
