Knowing that disorder is related to crime, it has become essential for criminologists to understand how and why certain individuals perceive disorder. Using data from the Perceptions of Neighborhood Disorder and Interpersonal Conflict Project, this study uses a fixed photograph of a neighborhood, to assess whether individuals "see" disorder cues. A final sample size of n=815 respondents were asked to indicate if they saw particular disorder cues in the photograph. The results show that certain personal characteristics do predict whether an individual sees disorder. Because of the experimental design, results are a product of the individual's personal characteristics, not of the respondent's neighborhood. These findings suggest that the perception of disorder is not as clear cut as once thought. Future research should explore what about these personal characteristics foster the perception of disorder when it is not present, as well as, how to fight disorder in neighborhoods when perception plays such a substantial role.

ABSTRACT Research on self-control theory (Gottfredson & Hirschi, 1990) consistently supports its' central proposition that low self-control significantly affects crime. The theory includes other predictions, which have received far less empirical scrutiny. Among these is the argument that self-control is developed early in childhood and that individual differences then persist over time. Gottfredson and Hirschi contend that once established by age ten, self-control remains relatively stable over one's life-course (stability postulate). To determine the empirical status of Gottfredson and Hirschi's "stability postulate," a meta-analysis on existing empirical studies was conducted. Results for this study support the contentions made by Gottfredson and Hirschi, however the inclusion of various moderating variables significantly influenced this relationship. Keywords: self-control, self-control stability, absolute stability, relative stability

There has been a tremendous amount of innovation in policing over the last 40 years, from community and problem-oriented policing to hot spots and intelligence-led policing. Many of these innovations have been subjected to empirical testing, with mixed results on effectiveness. The latest innovation in policing is the Bureau of Justice Assistance's Smart Policing Initiative (2009). Created in 2009, the SPI provides funding to law enforcement agencies to develop and test evidence-based practices to address crime and disorder. Researchers have not yet tested the impact of the SPI on the funded agencies, particularly with regard to core principles of the Initiative. The most notable of these is the collaboration between law enforcement agencies and their research partners. The current study surveyed SPI agencies and their research partners on key aspects of their Initiative. The current study uses mean score comparisons and qualitative responses to evaluate this partnership to determine the extent of its value and effect. It also seeks to determine the areas of police agency crime analysis and research units that are most in need of enhancement. Findings indicate that the research partners are actively involved in a range of aspects involved in problem solving under the Smart Policing Initiative, and that they have positively influenced police agencies' research and crime analysis functions, and to a lesser extent, have positively impacted police agencies' tactical operations. Additionally, personnel, technology, and training were found to be the main areas of the crime analysis and research units that still need to be enhanced. The thesis concludes with a discussion of the implications of these findings for police policy and practice.

The purpose of this preliminary study is to determine if sentencing disparities exist between male and female teachers who have been convicted of sexual misconduct with a student in Maricopa County, Arizona over a ten-year period. The hypothesis is that male teachers convicted of sexual misconduct with a student will receive harsher punishment than their female counterparts. In addition, this research will analyze the sentencing decisions of Arizona judges and prosecutors through plea-bargaining when compared with the presumptive sentence set by the Arizona Legislature. Issues that will be addressed include: a brief review of gender disparities in sentencing, sex offender sentencing, Arizona's rules of criminal procedure, and a review of the Arizona Revised Statutes pertaining to sexual crimes as well as the Arizona Supreme Court sentencing guidelines. The data set consists of fifteen different Maricopa County teachers who committed a sexual offense against a student and were convicted of that offense from February 2000 through September 2009. According to the results of this study, male teachers do receive harsher penalties than their female counterparts within Maricopa County.

Although recent studies have report that many stressors and strains (i.e., financial, educational and psychological) arise from being an adolescent mother, whether adolescent motherhood influences delinquency remains an unanswered empirical question. Using data from a nationally representative sample of adolescents (National Longitudinal Study of Adolescent Health), the current study examines the relationship between motherhood, depression, and delinquency (N = 676). The sample is comprised of solely females between ages 13 and 21-years-old. The female subjects were categorized either as an adolescent mothers, non-mother adolescents, or adult mothers. This study tests the following hypotheses: (1) adolescent mothers are prone to involvement in delinquent behavior; and, (2) adolescent mothers who experience depression are at greater risk of delinquent behavior. The results indicate that there is a decrease in delinquency among adolescent mothers who do not experience depression. However, there is an increase in delinquency among adolescent mothers who experience depression.

The link between childhood neuropsychological deficits and early-onset offending--the assumed precursor to life-course persistent offending--has been well established, yet the underlying mechanisms facilitating this relationship are less understood. Support is growing for the claim that self-control is a key mechanism that links neuropsychological deficits to early-onset offending. Despite this, findings are mixed with regard to the mediating effect of self-control in the relationship between neuropsychological deficits and antisocial behavior. These studies largely support the notion that self-control exerts a mediating effect on neuropsychological deficits when the offending being studied is less serious. Using data from the National Longitudinal Survey of Youth (NLSY), the present study seeks to build upon the existing literature by examining whether self-control mediates the relationship between neuropsychological deficits and two types of early-onset offending--low and high risk--as a means of testing core tenets of Gottfredson and Hirschi's (1990) and Moffitt's (1993) criminological theories. Findings show that while self-control and neuropsychological deficits independently predict general early-onset offending, these effects vary as a consequence of early-onset offender type. The results point to the need for future research to explore the possibility that the early-onset offender group that leads to persistent offending could be more precisely defined. Examining early-onset offending as a single construct limits our ability to make inferences about those offenders that are the most persistent in their offending patterns and, arguably, more likely to continue offending over the life-course.

On-officer video camera (OVC) technology in the field of policing is developing at a rapid pace. Large agencies are beginning to adopt the technology on a limited basis, and a number of cities across the United States have required their police departments to adopt the technology for all first responders. Researchers have just begun to examine its effects on citizen complaints, officers' attitudes, and street-level behavior. To date, however, there is no research examining how departmental policy and assignment of officers to a camera program affect officer behavior and opinions of the cameras. Policy and assignment have the potential to impact how officers react to the technology and can affect their interactions with citizens on a daily basis. This study measures camera activations by line officers in the Mesa Police Department during police-citizen encounters over a ten-month period. Data from 1,675 police-citizen contacts involving camera officers were subject to analysis. Net of controls (i.e., the nature of the crime incident, how it was initiated, officer shift, assignment, presence of bystanders and backup, and other situational factors), the bivariate and multivariate logistic regression analyses were used to examine how departmental policy (mandatory versus discretionary activation policy) and officer assignment (voluntary versus mandatory assignment) affected willingness to activate the cameras, as well as officer and citizen behavior during field contacts.

The presence of drug cartels within Mexico impacts U.S. national security, foreign policy, U.S. crime rates, and public health policy. Due to the direct and indirect effects that the cartels have on the United States, this paper examines the Mérida Initiative, the current U.S. anti-cartel policy, and makes several recommendations for future policy directions. Using official documents as well as current academic research, this paper examines the outcomes of past comparable policies that the United States has implemented in Colombia and Afghanistan to address the issue of drug trafficking. The paper then builds on the present successes of the Mérida Initiative by recommending several policies in the areas of international cooperation, agricultural development, Mexican targeting and enforcement, and U.S. law enforcement. This paper recommends that information sharing between countries should be increased to reduce the likelihood that pressure place on cartels will cause displacement; crop eradication cease and alternative crop development be implemented to reduce illicit crop growth; the joint Mexican-U.S. enforcement focus should move from high-value targets to more highly connected members; the United States should increase vetting for gun purchases to help keep guns out of the hands of cartel members; and domestic drug policies should shift toward treatment and demand-focused policies. By implementing the recommended policies, this paper suggests that the influence of cartels within Mexico as well as the United States may be reduced.

Efficiency of components is an ever increasing area of importance to portable applications, where a finite battery means finite operating time. Higher efficiency devices need to be designed that don't compromise on the performance that the consumer has come to expect. Class D amplifiers deliver on the goal of increased efficiency, but at the cost of distortion. Class AB amplifiers have low efficiency, but high linearity. By modulating the supply voltage of a Class AB amplifier to make a Class H amplifier, the efficiency can increase while still maintaining the Class AB level of linearity. A 92dB Power Supply Rejection Ratio (PSRR) Class AB amplifier and a Class H amplifier were designed in a 0.24um process for portable audio applications. Using a multiphase buck converter increased the efficiency of the Class H amplifier while still maintaining a fast response time to respond to audio frequencies. The Class H amplifier had an efficiency above the Class AB amplifier by 5-7% from 5-30mW of output power without affecting the total harmonic distortion (THD) at the design specifications. The Class H amplifier design met all design specifications and showed performance comparable to the designed Class AB amplifier across 1kHz-20kHz and 0.01mW-30mW. The Class H design was able to output 30mW into 16Ohms without any increase in THD. This design shows that Class H amplifiers merit more research into their potential for increasing efficiency of audio amplifiers and that even simple designs can give significant increases in efficiency without compromising linearity.

Driving under the influence (DUI) is a problem in American society that has received considerable attention over recent decades from local police agencies, lobby groups, and the news media. While punitive policies, administrative sanctions and aggressive media campaigns to deter drinking and driving have been used in the past, less conventional methods to restructure or modify the urban environment to discourage drunk driving have been underused. Explanations with regard to DUIs are policy driven more often than they are guided by criminological theory. The current study uses the routine activities perspective as a backdrop for assessing whether a relatively new mode of transportation - an urban light rail system - in a large metropolitan city in the Southwestern U.S. can alter behaviors of individuals who are likely to drive under the influence of alcohol. The study is based on a survey of undergraduate students from a large university that has several stops on the light rail system connecting multiple campuses. This thesis examines whether the light rail system has a greater effect on students whose routines activities (relatively unsupervised college youth with greater access to cars and bars) are more conducive to driving under the influence of alcohol. An additional purpose of the current study is to determine whether proximity to the light rail system is associated with students driving under the influence of alcohol, while controlling for other criminological factors
