Description
Research examining the long-term impacts of federal interventions under the Civil Rights of Institutionalized Persons Act on correctional institutions has been scant. The result has been a failure to understand the sustainability of reforms aimed at protecting the civil rights of confined persons. This dissertation examined the long-term reforms at the Arizona Department of Juvenile Corrections following a consent decree with the U.S. Department of Justice from 2004 to 2007. Interviews were conducted with current and former ADJC employees, juvenile justice advocates across Arizona, and county court representatives to determine how each of these groups perceived the status of the reforms at the ADJC. The findings of the current dissertation suggest that long-term reforms following consent decrees imposed on correctional institutions are possible. At the ADJC, the methods for securing the reform required that the agency reform its culture, implement a Quality Assurance process, revamp the Investigations and Inspections unit at the agency, and consider the perspectives of external agencies. One of the primary reasons why the department has been committed to making these reforms is because of the perceived loss of legitimacy and resources that would occur if they failed to reform. Such a failure for the agency could have potentially resulted in a closure of the agency. However, the increase in punitive and preventive policies used to enforce the reforms may have negative repercussions on the organizational culture in the long term. Policy implications for future CRIPA consent decrees are outlined, limitations are addressed, and suggestions for future research are made.

Description
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.

Description
The purpose of this research study provided observational techniques and Applied Behavior Analysis (ABA) prompts and fading procedures to analyze music therapist-child interaction for child with autism spectrum disorder. Impaired social interaction is the primary symptom of a child with autism spectrum disorder. However, social interaction exists everywhere and throughout human life. Therefore, to improve interaction is the primary and significant goal in music therapy treatment for a child with autism spectrum disorder. The music therapist designs a series of music therapy activity interventions in order to create a therapeutic environment, based on a child's interests and favorite activities. Additionally, the music therapist utilizes the music to build the quality of relationship and interaction with child and support child practicing interaction with the therapist. Then music therapist utilizes the process of interaction to improve child's social interaction. Once the child achieves at desired behavior, he/she has ability to apply the music therapy techniques independently in the real world situations, such as family and schools that the child has learned throughout the process of interaction with therapist. The participants were three children with autism spectrum disorder and two certified music therapists (MT-BC). The researcher calculated the number of prompts and cues which the therapists provided, and the number of appropriate responses by each child in each activity intervention. Then the researcher utilized Applied Behavior Analysis (ABA), prompt and fading procedure in order to analyze the progress of therapist-child interactions during the sessions. The result showed that the children had improvement in the interactions with their therapist.

Description
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

Description
A void exists in public administration, criminology, and criminal justice research as it relates to the study of power in American policing agencies. This has significant ramifications for academia and practitioners in terms of how they view, address, study, and interpret behaviors/actions in American policing agencies and organizations in general. In brief, mainstream research on power in organizations does not take into account relationships of power that do not act directly, and immediately, on others. By placing its emphasis on an agency centric perspective of power, the mainstream approach to the study of power fails to recognize indirect power relationships that influence discourse, pedagogy, mechanisms of communication, knowledge, and individual behavior/actions. In support of a more holistic inquiry, this study incorporates a Foucauldian perspective of power along with an ethnographical methodology and methods to build a greater understanding of power in policing organizations. This ethnography of an American policing organization illuminates the relationship between the exercise of power and the objectification of the subject through the interplay of relationships of communication, goal oriented activities, and relationships of power. Specifically, the findings demonstrate that sworn officers and civilian employees are objectified distinctly and dissimilarly. In summary, this study argues that the exercise of power in this American policing organization objectifies the civilian employee as a second class citizen.

Description
5-HT2A receptor (R) antagonists and 5-HT2CR agonists attenuate reinstatement of cocaine-seeking behavior (i.e., incentive motivation). 5-HT2Rs are distributed throughout the brain, primarily in regions involved in reward circuitry, including the prefrontal cortex (PFC), caudate putamen (CPu), and basolateral (BlA) and central (CeA) amygdala. Using animal models, we tested our hypotheses that 5-HT2ARs in the medial (m) PFC mediate the incentive motivational effects of cocaine and cocaine-paired cues; 5-HT2ARs and 5-HT2CRs interact to attenuate cocaine hyperlocomotion and functional neuronal activation (i.e, Fos protein); and 5-HT2CRs in the BlA mediate the incentive motivational effects of cocaine-paired cues and anxiety-like behavior, while 5-HT2CRs in the CeA mediate the incentive motivational effects of cocaine. In chapter 2, we infused M100907, a selective 5-HT2AR antagonist, directly into the mPFC and examined its effects on reinstatement of cocaine-seeking behavior. We found that M100907 in the mPFC dose- dependently attenuated cue-primed reinstatement, without affecting cocaine-primed reinstatement, cue-primed reinstatement of sucrose-seeking behavior, or locomotor activity. In chapter 3, we used subthreshold doses of M100907 and MK212, a 5-HT2CR agonist, to investigate whether these compounds interact to attenuate cocaine hyperlocomotion and Fos protein expression. Only the drug combination attenuated cocaine hyperlocomotion and cocaine-induced Fos expression in the CPu, but had no effect on spontaneous locomotion. Finally, in chapter 4 we investigated the effects of a 5- HT2CR agonist in the BlA and CeA on cocaine-seeking behavior and anxiety-like behavior. We found that CP809101, a selective 5-HT2CR agonist, infused into the BlA increased anxiety-like behavior on the elevated plus maze (EPM), but failed to alter cocaine-seeking behavior. CP809101 infused into the CeA attenuated cocaine-primed reinstatement and this effect was blocked by co-administration of a 5-HT2CR antagonist. Together, these results suggest that 5-HT2ARs in the mPFC are involved in cue-primed reinstatement, 5-HT2A and 5-HT2CRs may interact in the nigrostriatal pathway to attenuate cocaine hyperlocomotion and Fos expression, and 5-HT2CRs are involved in anxiety-like behavior in the BlA and cocaine-primed reinstatement in the CeA. Our findings add to the literature on the localization of 5-HT2AR antagonist and 5-HT2CR agonist effects, and suggest a potential treatment mechanism via concurrent 5-HT2AR antagonism and 5-HT2CR agonism.

Description
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.

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
Two groups of cochlear implant (CI) listeners were tested for sound source localization and for speech recognition in complex listening environments. One group (n=11) wore bilateral CIs and, potentially, had access to interaural level difference (ILD) cues, but not interaural timing difference (ITD) cues. The second group (n=12) wore a single CI and had low-frequency, acoustic hearing in both the ear contralateral to the CI and in the implanted ear. These `hearing preservation' listeners, potentially, had access to ITD cues but not to ILD cues. At issue in this dissertation was the value of the two types of information about sound sources, ITDs and ILDs, for localization and for speech perception when speech and noise sources were separated in space. For Experiment 1, normal hearing (NH) listeners and the two groups of CI listeners were tested for sound source localization using a 13 loudspeaker array. For the NH listeners, the mean RMS error for localization was 7 degrees, for the bilateral CI listeners, 20 degrees, and for the hearing preservation listeners, 23 degrees. The scores for the two CI groups did not differ significantly. Thus, both CI groups showed equivalent, but poorer than normal, localization. This outcome using the filtered noise bands for the normal hearing listeners, suggests ILD and ITD cues can support equivalent levels of localization. For Experiment 2, the two groups of CI listeners were tested for speech recognition in noise when the noise sources and targets were spatially separated in a simulated `restaurant' environment and in two versions of a `cocktail party' environment. At issue was whether either CI group would show benefits from binaural hearing, i.e., better performance when the noise and targets were separated in space. Neither of the CI groups showed spatial release from masking. However, both groups showed a significant binaural advantage (a combination of squelch and summation), which also maintained separation of the target and noise, indicating the presence of some binaural processing or `unmasking' of speech in noise. Finally, localization ability in Experiment 1 was not correlated with binaural advantage in Experiment 2.

Description
There are several visual dimensions of food that can affect food intake, example portion size, color, and variety. This dissertation elucidates the effect of number of pieces of food on preference and amount of food consumed in humans and motivation for food in animals. Chapter 2 Experiment 1 showed that rats preferred and also ran faster for multiple pieces (30, 10 mg pellets) than an equicaloric, single piece of food (300 mg) showing that multiple pieces of food are more rewarding than a single piece. Chapter 2 Experiment 2 showed that rats preferred a 30-pellet food portion clustered together rather than scattered. Preference and motivation for clustered food pieces may be interpreted based on the optimal foraging theory that animals prefer foods that can maximize energy gain and minimize the risk of predation. Chapter 3 Experiment 1 showed that college students preferred and ate less of a multiple-piece than a single-piece portion and also ate less in a test meal following the multiple-piece than single-piece portion. Chapter 3 Experiment 2 replicated the results in Experiment 1 and used a bagel instead of chicken. Chapter 4 showed that college students given a five-piece chicken portion scattered on a plate ate less in a meal and in a subsequent test meal than those given the same portion clustered together. This is consistent with the hypothesis that multiple pieces of food may appear like more food because they take up a larger surface area than a single-piece portion. All together, these studies show that number and surface area occupied by food pieces are important visual cues determining food choice in animals and both food choice and intake in humans.
