Description
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.

Description
Cannabis use has been purported to cause an amotivation-like syndrome among users. The purpose of this study was to investigate whether third party observers noticed amotivation among cannabis users. Participants in this study were 72 undergraduate university students, with a mean age of M=19.20 years old (SD=2.00). Participants nominated Informants who knew them well and these informants completed a version of the 18-item Apathy Evaluation Scale. Results indicated that more frequent cannabis use was associated with higher informant-reported levels of amotivation, even when controlling for age, sex, psychotic-like experiences, SES, alcohol use, tobacco use, other drug use, and depression symptoms (β=0.34, 95% CI: 0.04, 0.64, p=.027). A lack of motivation severe enough to be visible by a third party has the potential to have negative social impacts on individuals who use cannabis regularly.

Description
Vitamin B12, found only in animal products, is a water-soluble vitamin important for DNA methylation, purine and pyrimidine synthesis, and the myelination of nerves. Symptoms of vitamin B12 deficiency include anemia, gait disturbances, altered vibration proprioception, impaired vision, psychosis, depression, dementia-like illness, and ultimately death. Because vegetarians and vegans consume fewer animal products in their diet than omnivores, they are inherently more at risk for developing these symptoms of vitamin B12 deficiency. Thus, the purpose of this study is to examine the correlation between nervous system markers (balance, dexterity, and vibration sensitivity) and markers of vitamin B12 nutriture (serum B12 and serum holo-transcobalamin II) in a cross-sectional study (n=38). In addition, the impact of daily oral vitamin B12 supplementation on these markers in an 8-week randomized controlled trial was also examined (n=18). The results of the cross-sectional study revealed a moderate correlation (R=-0.351, p=0.031) between serum B12 and left-hand functional dexterity. The results of the intervention study revealed no significant time*group interactions for markers of nervous system functions and biochemical values (after the removal of outliers). In addition, the time*group interaction appeared to be larger for those individuals with a baseline serum B12 of less than 303 pmol/L. These results suggest that vitamin B12 supplementation may have a more pronounced effect on those individuals who are in a state of vitamin B12 depletion (<303 pmol/L serum concentration). In addition, the results also suggest that 8 weeks of oral supplementation is not a long enough period to create significant clinical change, and it is likely that improvements in neurological measures would require long-term supplementation.

Description
Life course criminology is characterized by a two-pronged approach to research. The first branch emphasizes social integration and involvement with pro-social institutions as turning points in the criminal career. The second branch of this work assesses how access to the institutions that facilitate social integration are conditioned by factors such as involvement in the criminal justice system. Theories of capital are chiefly concerned with social integration and the continuity of conventionality, conformity, and prosperity offered through social ties and social networks. Absent from life course criminology is a better understanding of how different forms of criminal capital can influence access to institutions like higher education, marriage, and employment during the transition to adulthood. Drawing on insights from distinct bodies of literature on peers, capital, and status attainment, the present study elaborates on the influence of criminal capital for (un)successful transitions to adulthood. Using three waves of data from the National Longitudinal Study of Adolescent to Adult Health (“Add Health”), the effects of adolescent criminal social capital on criminal cultural and human capital, and subsequent educational, occupational, and marital attainment in early adulthood are examined. Results from a series of regression models demonstrate that criminal social capital has minimal effects on fatalistic beliefs or thoughtful and reflective decision making, and that these forms of criminal capital generally have inconsistent effects on later life transitions. Implications for theory and future research are discussed.

Description
In the United States, approximately 400,000 youth are in out-of-home care in the custody of child protection systems (CPS). They are incarcerated, but not as punishment for a crime. States place youth in CPS custody for many different reasons, centered around legal determinations of families’ failure to provide adequate care. Such youth are forcibly separated from their biological (“bio”) families and required to live in shelters, group homes, and foster households at the threat of arrest. Through the socio-legal concept of parens patriae, the government assumes responsibility for their safety and development. In other words, the state assumes the role of parents to children it places in CPS. Still, despite years of social work research, three fundamental questions remain about CPS for criminology. First, criminologists are beginning to recognize the overlap between criminology and CPS but lack a theoretical framework for analyzing that intersection. Second, the proper role of the state in youth development and the measurement of its relative success are of central importance to criminal justice, but at best loosely defined. Finally, this dissertation asks: how do entering CPS custody, growing up in state care, and (someday) exiting CPS shape the experiences and perceptions of CPS youth? Given the attenuated social processes associated with CPS, criminologists might expect youth to experience significant barriers to transitioning successfully to adulthood. At the same time, therapeutic assessment and treatment in CPS should ameliorate those barriers. This dissertation addresses that theoretical paradox in eight chapters. After an introductory overview, Chapter Two posits social control, social support, and agency over the life course as a theoretical framework for understanding the implications of growing up in CPS. Chapter Three details the phronetic and ethnographic approach of the study, designed to encounter the perspectives of youth themselves in their “natural” setting. Chapters Four through Seven present findings from interviews with participants in an arts-based therapy program for youth in CPS (n=33). Chapter Eight concludes the study with a discussion of the implications of this work for criminological research, juvenile justice policy, and youth who grow up in CPS.

Description
The purpose of this study is to examine how sex influences the physical demandof weapons used in homicide. The study focuses on two research questions using data
from Newark, New Jersey: (1) Does sex influence the use of a weapon that is more or
less physically demanding to commit homicide? and (2) Does the sex dyad of the
offender and victim influence using a weapon that is more or less physically demanding?
The descriptive analysis shows significant relationships between the sex dyad of the
offender and victim in homicide and the level of physical demand used to perpetrate
homicide. The logistic multinomial regression analysis shows suspect sex and suspect
and victim sex dyads significantly predict the physical demand of the weapons used to
perpetrate homicide compared to those who utilized weapons of low physical demand.
The results support the need to challenge traditional perspectives regarding the role of sex
in criminal decision-making and seek to integrate more intersectional and gendered
explanations into neoclassical theories of criminal behavior. Theoretical implications and
future avenues of research are also discussed.
