Development of a Combined Model of College Student Alcohol-associated Condomless Sex
… use a mixed-methods approach to develop a novel model of college student alcohol-associated condomless sex that combines elements from well-established health behavior theories. In Aim 1, multilevel structural regression models were estimated to predict condomless vaginal intercourse in a sample …

Multiclass intermodal network model : the use of combined model on system evaluations
… amount of time and cost. This study builds a combined intermodal network model and evaluation system specifically for intermodal transportation systems. It includes two main parts. The first part is to construct a combined network equilibrium model (CNEM) for multiclass travelers. The combined …

Cognitive and Behavioral Predictors of Fall Risk in Parkinson Disease
… there is a need to develop a comprehensive model incorporating elements from each of the areas known to have a relationship with fall behaviors in PD. Such information could result in improved identification and treatment of PD patients at higher risk of falls. This study used stepwise …

Merging Task-Centered Social Work and Motivational Interviewing in Outpatient Medication Assisted Substance Abuse Treatment: Model Development for Social Work Practice
… practice gap, this dissertation followed a model development paradigm consisting of several phases. Based on the task-centered model of social work practice and motivational interviewing, a new combined model was construed. The two underlying models were analyzed and synthesized, using …

An altimeter waveform model for combined surface and volume scattering
… study of pulse penetration effects, a waveform model for combining surface and volume scattering effects in the estimation of the radar altimeter returns recorded over continental ice and snow is developed and discussed. The surface scattered waveform model is based on the well-known impulse …

Neural networks as a tool for statistical modeling
… often as alternatives to traditional statistical models. As a result, their performance needs to be examined in a statistical framework. Following a brief overview of many types of neural networks, details concerning the implementation of the single hidden layer feedforward neural network (SHLFNN) …

Vulnerability to adverse consequences of drinking and problem drinker status as predicted by risky drinking behaviours, drug use, sex differences and affect : a test of multiple models /
… for overall alcohol consumption. Four models were developed that were intended to test the predictive ability of these factors, three of which tested the predictor sets separately and a fourth which tested them in a combined model. In addition, two distinct criterion variables were …

The Political Economy of U.S. Public Pension Plans and Their Unfunded Liabilities
… methodology of Congleton and Shughart (1990) to model underfunding of state-level public pension plans using the median voter theorem, along with the theory of "capture" by special interest groups, and a combined model of the two. With panel data from 2001 to 2009, the paper finds that the …

Tax expenditures: report utilization by state policy makers
… and report use and (2) applying three path models of technical information use to tax expenditure reports. Data were gathered from report preparers-legislative staff persons and legislators. The adoption of recommended standard features was examined. Commonly adopted core features and …

Reactive Prediction Models for Cloud Resource Estimation
… is to propose a new reactive resource estimation model to achieve more reasonable resource allocation and higher server utilization for cloud providers. The model is flexible enough to adapt to different situations given the current server utilization, the customer loyalty, the price of the …

Using Learning to Rank Approach to Promoting Diversity for Biomedical Information Retrieval with Wikipedia
… of the traditional information retrieval (IR) models, the independent relevance assumption is taken, which assumes the relevance of a document is independent of other documents. However, the pitfall of this is the high redundancy and low diversity of retrieval result. This has been seen in many …

Factors related to depression in end-stage renal disease patients
… functioning, overall quality of life, and age. A combined model of social functioning, sleep quality, and age provides a stronger prediction than any variable alone. Results suggest that targeting social functioning, sleep quality, and age should be the focus of future studies examining …

Estimating uncertainty models for speech source localization in real-world environments
… as part of a simple probabilistic generative model of localization cues. We combine this localization cue model with a mixture model of speech log-spectra and use this combined model to do speech source separation. For both source localization and source separation, we show significantly …

An exploratory study of factors that influence student user success in an academic digital library.
… of digital libraries calls for appropriate models to study user success. Calls have been made to incorporate into these models factors that capture the interplay between people, organizations, and technology. In order to address this, two research questions were formulated: (1) To what …
