To accomplish this objective, thirty-eight fentanyl-related substances, in addition to the MOR …

Measuring The Social And Emotional Skills Of Hispanic American Students In An Afterschool Karate Program, Noel Adrian Castillo

Theses and Dissertations

The social and emotional learning skills of children play an important role in their development. These skills include persistence, self-control, and social competence. The lack of these skills can often be a predictor of future criminality and antisocial behavior. Aggressiveness in youth plays a key role in violence among juveniles. Violent crime committed by juvenile offenders has been a longstanding issue facing the United States criminal justice system. It lacks an effective prevention method, disproportionately affects minority youth, and is often cited as a future predictor of criminality.

The purpose of this quasi-experimental, one-group, pretest–posttest design study, was twofold. First, …

Unsolvable? Assessing The Accuracy Of Missing Person Case Data, Scott Duncan

Theses and Dissertations

Annually, about 100,000 individuals are reported missing to authorities in the US. Fortunately, the majority of these investigations are resolved quickly with the persons being accounted for and reunited with loved ones. Conversely, the number of cases that remain open represent dilemmas for police as the incidents could be connected to unsolved homicides, other violent crimes, or endangered persons. Despite the commonality of missing persons, research on the topic is scant. Predominantly, published studies on missing persons focus on investigations from European countries. In 2008, the US Department of Justice launched the National Missing and Unidentified Person System (NamUs), a …

Integrating A Modified Pulse Amplitude Modulation (Pam4) Scheme With Two Spatially Multiplexed Channels In Optical Fiber Communication Systems, Bilas Chowdhury

Theses and Dissertations

A multi-input multi-output (MIMO) based optical fiber multiplexing architecture known as Spatial Domain Multiplexing (SDM) adds a new dimension to optical fiber communication systems by spatially reusing the optical frequencies. SDM allocates different spatial location for different input signals based on the input launch angles. These input signals propagate helically inside the carrier fiber. They abide total internal reflection and exit as concentric donut shaped rings while travelling the fiber. These SDM channels do not exhibit any crosstalk or intersymbol interference. SDM systems can also complement different modulation techniques such as Return to Zero (RZ), Non-Return to Zero (NRZ), and …

Situational Judgement Selection Test Utility: Implications For Police Turnover, Marshall Alan Jones

Theses and Dissertations

Police agencies increasingly find attracting, recruiting, selecting, and retaining police officers challenging. Officer candidates selected can have up to a 25 percent fail rate in basic police training, while probationary officers in field training can fail to complete training with rates as high as 40 percent. Police selection batteries often include situational judgment tests (SJTs) designed to help ensure legal and proper hiring standards. The scores of SJTs, and other selection battery scores, are often filed once the hiring process is complete. This study explored the potential SJT selection battery scores may have in the prediction of field training and …

Modified Force/Displacement-Based Procedure For Performance-Based Seismic Design Of Regular Rc Frames, Soha Hassan Nashaat Elkassas

Theses and Dissertations

Performance-based seismic design has been the thrust of international research on earthquake engineering for the past 20 years. The major decisive factor for the success of its most recent framework is the development of efficient “preliminary design” methodologies that follow common design formats in order to maintain the process at an affordable level of complexity for practitioners. Using the traditional force-based seismic design method for this purpose, though simple and easy, will be inefficient because it designs structures to only one performance objective (which is life safety), and any other performance objective would be part of the drift check that …

Developing A Bio-Based Wood Composite Using Refined Cottonseed Protein Adhesives., Julianna Nicole Stratton

Theses and Dissertations

A growing market of environmentally-conscious consumers combined with a progression toward ‘greener’ products has caused the wood industry to investigate adhesives containing little to no formaldehyde. This study examines cottonseed proteins’ ability to bind southern yellow pine for plywood applications. Three-ply plywood panels were constructed with varying blends of cottonseed protein isolate (CSPI), soy protein, and phenol: formaldehyde adhesive. Wet and dry shear testing revealed that while the novel adhesives did not perform as well as a commercial control, the CSPI and soy adhesives generated similar shear strengths. Another set of boards were created, varying the CSPI amount added and …

An Evaluation Of The Impact Of Leading Pedestrian Interval Signals In Nyc, Jeremy J. Sze

Theses and Dissertations

I evaluated the impact of the phased introduction of Leading Pedestrian Interval Signals (LPIs) on collision and injury outcomes at 12,987 signalized traffic intersections in New York City over the course of 25 quarters from 2012 to 2018. An intersection is treated when a LPIs is installed to give pedestrians lead time to cross the street before vehicles are allowed to move. Outcomes from NYPD’s Motor Vehicle Collisions data were matched to signalized intersections. I hypothesize that LPIs would reduce collisions and reduce injuries for pedestrians at intersections. A difference in difference fixed effects panel regression was used to identify …
