Criminologists have directed significant theoretical and empirical attention toward the institution of marriage over the past two decades. Importantly, the momentum guiding this line of research has increased despite the fact that people are getting married far less often and much later in the life course than in any point in American history. The aim of this dissertation is to address this disconnect by focusing attention to nonmarital romantic relationships and their instability during emerging adulthood. To do so, it uses data from the Pathways to Desistance Study, a longitudinal study of 1,354 at-risk males and females who were adjudicated from the juvenile and adult systems in Phoenix and Philadelphia between 2000 and 2003. The project focuses attention to the following issues: (1) the effect of romantic dissolution on aggressive and income-based offenses; (2) the extent to which strain
egative emotionality and peer influence/exposure account for the effect of romantic dissolution on crime; and (3) the extent to which certain relationship and individual circumstances moderate the effect of romantic dissolution. The models reveal a few key findings. First, romantic dissolution is strongly related to an increase in both aggressive and income-based crime, but is more strongly related to income-based crime. Second, the effect of romantic dissolution is reduced when measures of strain
egative emotionality and peer influence/exposure measures are added to models, but the peer influence/exposure measures account for the strongest reduction. Finally, romantic dissolution does not serve as a positive life event among these at-risk youth, but its effect is exacerbated under a number of contexts (e.g. when an individual is unemployed). This study closes with a summary of these findings as well as its key limitations, and offers insight into potential policy implications and avenues of future research.

The Zero Tolerance Policy began appearing in secondary schools in the early 1990's. In the late 1980's, crimes committed by juveniles were at an all-time high. Fears that the violence would spill onto campus propelled lawmakers and school officials to take preventative measures. With the creation of the Gun-Free School Zone Act of 1990 and Gun-Free Act of 1994, any individual caught with a weapon on campus would be found in violation of the Act and be punishable by law. In addition to the Acts, School Resource Officers (SROs) became more prominent on campus. SROs were originally on campus to teach drug prevention programs, however SROs began to take on more of a disciplinary role to support the Zero Tolerance Policy. Furthermore, educators began turning towards SROs to handle less serious incidents such as behavioral outbursts. As SROs took a more active role, arrests among students started to rise. Many think this is a direct pathway to our criminal justice system, more commonly known as the school-to-prison pipeline. This pipeline disproportionately affects African Americans. This paper will examine the creation, aims and purpose of the Zero Tolerance Policy as well as what incidents helped create and install the policy. This paper will look at what the Zero Tolerance Policy looks like since it has been enacted. Moreover, there will be a focus on which students are affected the most and if this policy will lead to criminal justice contact in the future. Lastly, alternatives to the Zero Tolerance Policy will be discussed and if the policy can be improved or should it be eliminated.

Criminological theories have long incorporated personality traits as key explanatory factors and have generally relied on assumptions of trait stability. However, growing evidence from a variety of fields including criminology, psychology, and neurobiology is demonstrating that personality traits are malleable over the life-course, and substantial individual variation exists in the developmental patterns of personality traits over time. This research is forcing criminologists to consider how and why “enduring” individual characteristics may change over the life course in ways that are meaningfully related to offending. Two traits that have been consistently linked to offending and conflated in key criminological theories (i.e. Gottfredson and Hirschi’s self-control theory), impulsivity and sensation seeking, have recently been shown to be independent personality traits with different normative maturational timetables and biological underpinnings. This dissertation extends this work by examining developmental patterns of impulsivity and sensation seeking and social sources of variation in these traits with the Family and Community Health Survey, a longitudinal data set that consists of approximately 900 African American youth and their families followed from late childhood to their late-twenties. Multiple longitudinal modeling methods are employed (hierarchical linear modeling and group-based trajectory modeling) to address this research agenda. Results from this dissertation lead to four broad conclusions. First, and in support of existing research, there is substantial variability in developmental trajectories of impulsivity and sensation seeking. Average developmental trajectories of these traits greatly mask the degree of individual variability in developmental patterns that exists. Second, social factors are significantly associated with levels of impulsivity and sensation seeking. Socio-environmental experiences characterized by hostility and unsupportiveness are generally associated with elevated levels of impulsivity and sensation seeking while socio-environmental experiences characterized by warmth and supportiveness are associated with lower levels of impulsivity and sensation seeking. Third, sex differences in developmental patterns of impulsivity are nonexistent while sex differences in developmental patterns of sensation seeking are significant. Finally, with few exceptions, predictors of trait levels operate in a general fashion such the same factors typically explain both male and female trait levels and produce similar effects on impulsivity and sensation seeking.
