War On Drugs: Examining The Effects On Social Disorganization And Crime In Cities, Ruben Ortiz

Master’s Theses and Projects

The work of Shaw and Mckay (1942) paved the way for researchers to study inner-city crime by focusing on the environment and its effects on residents. Social disorganization, characterized by weakened institutions led researchers to analyze and predict patterns of crime in urban areas. Researchers argue that social disorganization theory arguments developed from this approach, but lost appeal among researchers due to limited empirical tests. The theory experienced a renewed interest in the 1980s, as structural factors (e.g. poverty, heterogeneity, residential mobility, racial inequality, and family disruption) were considered, all of which allowed researchers to study patterns of crime in …

College Sexual Assault: Student Risk Of Victimization Off-Campus, Danielle Christenson

Master’s Theses and Projects

Although there is a plethora of research focusing on college sexual assault victimization and risk factors respectively, few studies have specifically examined the location of these incidents as a risk factor. Among the few studies examining sexual assault location, the researchers determined college students are more likely to be victimized off-campus. Fisher, Cullen and Turner (2000) found that 66.3% of sexual assaults of college-aged females took place off-campus compared to 33.7% that occurred on-campus (Fisher et al., 2000). In a similar study, Nobles, Fox, Khey and Lizotte (2012) examined the role of location in college crime (including sexual assault). The …

Ownership Of Images: The Prevalence Of Revenge Porn Across A University Population, Corrie Mccue

Master’s Theses and Projects

Since the Internet was first established in the late 1960s it has become significantly easier to gain access to. Email, bulletin board systems, and Internet gaming came to be in the 1970s. Internet pornography soon followed and access has continued to increase.

A new trend in pornography includes interactive pornographic websites, which offers users the ability to upload and share pornographic materials. This ability allows individuals to not only post their own photos or videos, but also the photos and videos of others who may, or may not, have consented to such distribution. Nonconsensual pornography also referred to as “revenge …

The Fair And Impartial Spectator, Vernon L. Smith

Economics Faculty Articles and Research

Adam Smith’s metaphor of the impartial spectator is an essential element in understanding his model of the maturation process whereby people learn to follow general rules that honor the human sentiments of gratitude and resentment in others. Through the impartial spectator human action, subject to error, is governed by self-command. Smith’s model is presented in the form of a series of propositions.

Cost Savings And Cost Effectiveness Of The Cuyahoga County Sexual Assault Kit Task Force, Rachel Lovell, Mendel Singer, Daniel Flannery

Begun Center for Violence Prevention Research and Education Reports and Briefs

We conducted an analysis of the cost savings and cost effectiveness of the Cuyahoga County Sexual Assault Kit (SAK) Task Force on all unsubmitted SAKs tested as of January 1, 2016. We explored the total tangible and intangible costs to victims associated with unsubmitted SAKs and the total cost of testing and investigated those SAKs. Our analysis estimates the total cost savings of future sexual assaults averted due to the SAK Task Force as of January 1, 2016 is $48.2 million dollars. Conservative estimates suggest the SAK Task Force’s efforts will produce a net savings of $38.7 million dollars to …

The Maximum Likelihood Estimation procedure is used to estimate the parameters of the distribution. R codes are developed to implement the estimation procedure. A simulation study is carried out to test the performance of the algorithm. AIC and BIC criterion are used to compare the distributions. It is shown that the fit of the Esscher …

The Goldilocks Dilemma: Impacts Of Multicollinearity -- A Comparison Of Simple Linear Regression, Multiple Regression, And Ordered Variable Regression Models, Grayson L. Baird, Stephen L. Bieber

Journal of Modern Applied Statistical Methods

A common consideration concerning the application of multiple linear regression is the lack of independence among predictors (multicollinearity). The main purpose of this article is to introduce an alternative method of regression originally outlined by Woolf (1951), which completely eliminates the relatedness between the predictors in a multiple predictor setting.

Solution To The Multicollinearity Problem By Adding Some Constant To The Diagonal, Hanan Duzan, Nurul Sima Binti Mohamaed Shariff

Journal of Modern Applied Statistical Methods

Ridge regression is an alternative to ordinary least-squares (OLS) regression. It is believed to be superior to least-squares regression in the presence of multicollinearity. The robustness of this method is investigated and comparison is made with the least squares method through simulation studies. Our results show that the system stabilizes in a region of k, where k is a positive quantity less than one and whose values depend on the degree of correlation between the independent variables. The results also illustrate that k is a linear function of the correlation between the independent variables.

Symmetric Variants Of Logistic Smooth Transition Autoregressive Models: Monte Carlo Evidences, Olaoluwa S. Yaya, Olanrewaju I. Shittu

Journal of Modern Applied Statistical Methods

The Smooth Transition Autoregressive (STAR) models are becoming popular in modeling economic and financial time series. The asymmetric type of the model is the Logistic STAR (LSTAR) model, which is limited in its applications as a result of its asymmetric property, which makes it suitable for modelling specific macroeconomic time series. This study was designed to develop the Absolute Error LSTAR (AELSTAR) and Quadratic LSTAR (QLSTAR) models for improving symmetry and performance in terms of model fitness. Modified Teräsvirta’s Procedure (TP) and Escribano and Jordá's Procedure (EJP) were used to test for nonlinearity in the series. The performance of the …

Determination Of Optimal Tightened Normal Tightened Plan Using A Genetic Algorithm, Sampath Sundaram, Deepa S. Parthasarathy

Journal of Modern Applied Statistical Methods

Designing a tightened normal tightened sampling plan requires sample sizes and acceptance number with switching criterion. An evolutionary algorithm, the genetic algorithm, is designed to identify optimal sample sizes and acceptance number of a tightened normal tightened sampling plan for a specified consumer’s risk, producer’s risk, and switching criterion. Optimal sample sizes and acceptance number are obtained by implementing the genetic algorithm. Tables are reported for various choices of switching criterion, consumer’s quality level, and producer’s quality level.

Model-Based Outlier Detection System With Statistical Preprocessing, D. Asir Antony Gnana Singh, E. Jebalamar Leavline

Journal of Modern Applied Statistical Methods

Reliability, lack of error, and security are important improvements to quality of service. Outlier detection is a process of detecting the erroneous parts or abnormal objects in defined populations, and can contribute to secured and error-free services. Outlier detection approaches can be categorized into four types: statistic-based, unsupervised, supervised, and semi-supervised. A model-based outlier detection system with statistical preprocessing is proposed, taking advantage of the statistical approach to preprocess training data and using unsupervised learning to construct the model. The robustness of the proposed system is evaluated using the performance evaluation metrics sum of squared error (SSE) and time to …

Bayesian Estimation Of P[Y < X] Based On Record Values From The Lomax Distribution And Mcmc Technique, Mohamed A. W Mahmoud, Rashad M. El-Sagheer, Ahmed A. Soliman, Ahmed H. Abd Ellah

Journal of Modern Applied Statistical Methods

Our interest is in estimating the stress-strength reliability R = P[Y < X], where X and Y follow the Lomax distribution with common scale parameter. We discuss the problem in the situation where the stress measurements and the strength measurements are both in terms of records. Firstly, we obtain the MLE of R in general case (the common scale parameter is unknown). The MLE of the three unknown parameters can be obtained by solving one non-linear equation. We provide a simple fixed point type algorithm to find the MLE. We propose percentile bootstrap confidence intervals of R. A Bayes …

Graphing Effects As Fuzzy Numbers In Meta-Analysis, Christopher G. Thompson

Journal of Modern Applied Statistical Methods

Prior to quantitative analyses, meta-analysts often explore descriptive characteristics of effect sizes. A graphic is proposed that treats effect sizes as fuzzy numbers. This plot can provide meta-analysts with such information such as heterogeneity of effects, precision of estimates, possible clusters, and existence of outliers.

Principal Component Preliminary Test Estimator In The Linear Regression Model, Sivarajah Arumairajan, Pushpakanthie Wijekoon

Journal of Modern Applied Statistical Methods

A Preliminary Test Estimator is introduced based on Principal Component Regression Estimator defined in the linear regression model when the stochastic restrictions are available in addition to the sample information, and when the explanatory variables are multicollinear. It is further developed as a large sample preliminary test estimator by using Wald (WA), Likelihood Ratio (LR), and Lagrangian Multiplier (LM) tests. Stochastic properties of this estimator based on F test as well as WA, LR, and LM tests are derived, and the performance of the estimator is compared using WA, LR, and LM tests with respect to Mean Square Error Matrix …

The Biggest Lies On The Internet: Using Real Life Examples To Help Students Master Information Literacy Concepts, Lucinda Rush

Libraries Faculty & Staff Presentations

Teaching students how the information cycle works is a common instructional goal for academic librarians. Oftentimes we do this by showing them examples of how things work under ideal circumstances. By sharing case studies in information cycles that have short‐circuited, either due to moral panics about the impact of new technologies or due to poor reporting gone bad on social media, we can teach students how to be critical readers of empirical research‐based claims. In this lightening talk, the presenter will provide examples of incorporating these case studies into library instruction settings and share ideas that will help to bridge …

New Metaphors For Networked Learning, Caroline A. Haythornthwaite

School of Information Studies - Faculty Scholarship

As networked learning leaves designed spaces and becomes diffused and re-infused through open, online information sharing and knowledge construction, what metaphors will frame our next steps, our next inquiries? In keeping with the conference theme of ‘Looking Back – Moving Forward’, this presentation will engage with where we are in the sea of change, and how our current understanding of networks, learning and knowledge will take us forward into new areas of inquiry. Elsewhere I have been advocating for a reclamation of the term ‘e-learning’ that takes us beyond the design and use of the closed LMS and VLE systems …
