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
Patients with schizophrenia have impaired cognitive flexibility, as evidenced by behaviors of perseveration. Cognitive impairments may be due to dysregulation of glutamate and/or loss of neuronal plasticity in the medial prefrontal cortex (mPFC). The purpose of these studies was to examine the effects of mGluR5 positive allosteric modulators (PAMs) alone and in combination with the NMDAR antagonist MK-801, a pharmacological model of schizophrenia. An operant-based cognitive set-shifting task was utilized to assess cognitive flexibility, in vivo microdialysis procedures to measure extracellular glutamate levels in the mPFC, and diolistic labeling to assess the effects on dendritic spine density and morphology in the mPFC. Results revealed that chronic administration of the mGluR5 PAM CDPPB was able to significantly reduce the effects of chronically administered MK-801 on both behavioral perseveration and glutamate neurotransmission. Results also showed that CDPPB had no evidence of an effect on dendritic spine density or morphology, but the mGluR5 negative allosteric modulator fenobam caused significant increases in spine density and the frequency of occurrence of spines with smaller head diameters. Conclusions include that CDPPB is able to reverse MK-801 induced cognitive deficits as well as alterations in mPFC glutamate neurochemistry. The culmination of these studies add further support for targeting mGluR5 with PAMs as a novel mechanism to alleviate cognitive impairments in patients with schizophrenia.

Description
Arcadia Elementary School is an urban Title 1 school that serves 800 students in kindergarten through eighth grade. The school uses a commercial program called Make Your Day to manage student behavior. This program, aligned to the tenets of Positive Behavior Interventions and Supports (PBIS), meets the needs of most students but not the most frequent classroom disruptors. This mixed methods participatory action research study explores the how an understanding of a frequently disruptive student's ecology can lead to more effective support and improved behavioral outcomes. The Behavior Intervention Team process consists of effective data tracking tools and practices and a team-based, data-driven approach to student behavior analysis and is a model for how urban schools can leverage existing resources to better support disruptive students.

Description
Like individual organisms, complex social groups are able to maintain predictable trajectories of growth, from initial colony foundation to mature reproductively capable units. They do so while simultaneously responding flexibly to variation in nutrient availability and intake. Leafcutter ant colonies function as tri-trophic systems, in which the ants harvest vegetation to grow a fungus that, in turn, serves as food for the colony. Fungal growth rates and colony worker production are interdependent, regulated by nutritional and behavioral feedbacks. Fungal growth and quality are directly affected by worker foraging decisions, while worker production is, in turn, dependent on the amount and condition of the fungus. In this dissertation, I first characterized the growth relationship between the workers and the fungus of the desert leafcutter ant Acromyrmex versicolor during early stages of colony development, from colony foundation by groups of queens through the beginnings of exponential growth. I found that this relationship undergoes a period of slow growth and instability when workers first emerge, and then becomes allometrically positive. I then evaluated how mass and element ratios of resources collected by the ants are translated into fungus and worker population growth, and refuse, finding that colony digestive efficiency is comparable to digestive efficiencies of other herbivorous insects and ruminants. To test how colonies behaviorally respond to perturbations of the fungus garden, I quantified activity levels and task performance of workers in colonies with either supplemented or diminished fungus gardens, and found that colonies adjusted activity and task allocation in response to the fungus garden size. Finally, to identify possible forms of nutrient limitation, I measured how colony performance was affected by changes in the relative amounts of carbohydrates, protein, and phosphorus available in the resources used to grow the fungus garden. From this experiment, I concluded that colony growth is primarily carbohydrate-limited.

Responding to the allegedly biased research reports issued by large investment banks, the Global Research Analyst Settlement and related regulations went to great lengths to weaken the conflicts of interest faced by investment bank analysts. In this paper, I investigate the effects of these changes on small and large investor confidence and on trading profitability. Specifically, I examine abnormal trading volumes generated by small and large investors in response to security analyst recommendations and the resulting abnormal market returns generated. I find an overall increase in investor confidence in the post-regulation period relative to the pre-regulation period consistent with a reduction in existing conflicts of interest. The change in confidence observed is particularly striking for small traders. I also find that small trader profitability has increased in the post-regulation period relative to the pre-regulation period whereas that for large traders has decreased. These results are consistent with the Securities and Exchange Commission's primary mission to protect small investors and maintain the integrity of the securities markets.

Description
African American students are one of the historically disadvantaged groups by the public education system. Related to this phenomenon is the overrepresentation of African American children in special education due to disability diagnoses, which has been referred to as disproportionality. It has been hypothesized that disproportionality is due to poverty or a cultural mismatch between primarily white, middle-class teachers and African American students. Using a sample of African American children in special education from Memphis, Tennessee, this secondary data analysis explored the relationship between children's behavioral and educational outcomes and their environment, efficacy beliefs, and the impact of an intervention, the Nurse-Family Partnership. This study also explored differences in children's externalizing and internalizing behaviors by self-report, children's mothers and children's teachers. Using multiple imputation and regression analyses, the results indicated the following: 1) children's self-efficacy and number of hours in special education were associated with children's academic achievement, 2) mothers' and teachers' ratings of children's behaviors differed from children's self-report of their behaviors, 3) African American boys are more likely to experience acting-out behaviors, while African American girls are more likely to experience anxiety and depression, 4) children were less likely to experience anxiety and depression if their mother believed that she had control over circumstances in her life. These findings are discussed in light of Brofenbrenner's ecological systems theory and Bandura's social cognitive theory.

Description
A notable feature of advanced eusocial insect groups is a division of labor within the sterile worker caste. However, the physiological aspects underlying the differentiation of behavioral phenotypes are poorly understood in one of the most successful social taxa, the ants. By starting to understand the foundations on which social behaviors are built, it also becomes possible to better evaluate hypothetical explanations regarding the mechanisms behind the evolution of insect eusociality, such as the argument that the reproductive regulatory infrastructure of solitary ancestors was co-opted and modified to produce distinct castes. This dissertation provides new information regarding the internal factors that could underlie the division of labor observed in both founding queens and workers of Pogonomyrmex californicus ants, and shows that changes in task performance are correlated with differences in reproductive physiology in both castes. In queens and workers, foraging behavior is linked to elevated levels of the reproductively-associated juvenile hormone (JH), and, in workers, this behavioral change is accompanied by depressed levels of ecdysteroid hormones. In both castes, the transition to foraging is also associated with reduced ovarian activity. Further investigation shows that queens remain behaviorally plastic, even after worker emergence, but the association between JH and behavioral bias remains the same, suggesting that this hormone is an important component of behavioral development in these ants. In addition to these reproductive factors, treatment with an inhibitor of the nutrient-sensing pathway Target of Rapamycin (TOR) also causes queens to become biased towards foraging, suggesting an additional sensory component that could play an important role in division of labor. Overall, this work provides novel identification of the possible regulators behind ant division of labor, and suggests how reproductive physiology could play an important role in the evolution and regulation of non-reproductive social behaviors.

Description
During the past decade, the Chinese bond market has been rapidly developing. The percentage of bond to total social funding is constantly increasing. The structure and behavior of investors are crucial to the construction of China’s bond market. Due to specific credit risks, bond market regulation usually involves in rules to control investor adequancy. It is heatedly discussed among academia and regulators about whether individual investors are adequate to directly participate in bond trading. This paper focuses on the comparison between individual and institutional bond investors, especially their returns and risks. Based on the comparison, this paper provides constructive suggestions for China’s bond market development and the bond market investor structure.

ABSTRACT
School discipline practices have traditionally been reactive and punitive in nature. Students violating a school district’s code of conduct were often met with exclusionary discipline policies such as out-of-school suspensions, long-term suspensions, and expulsions. Districts attempted to resolve these practices by creating alternative education schools to house students with high numbers of office discipline referrals, rather than have them withdrawn from school. This practice has created in some instances, a school-to-prison pipeline. In this study, for 2015-2016, there were 22 students previously enrolled in the district’s alternative education school, Spirit Academy ranging in third through eighth grades. The students were then transferred back to their home schools with supports via student behavior specialists, student behavior interventionists, and a research-based data tracking tool, Check In/Check Out, to determine the level of the model’s effectiveness. The six students out of the 22 were selected for this case study analysis because of the fidelity of the data collection at their school sites. Another factor was to include a broad cross-section of students rather than focus solely on a selected grade-level. The study showed three students who successfully passed Check In/Check Out due to higher scores in all three of their skills, while two students showed the exact opposite. Office discipline referrals (ODRs) also indicated mixed results as three students increased their number of ODRs and three showed decreases. Report cards were also mixed as only two of the students showed higher percentages in reading. For math, one student showed an increase. Finally, the school climate survey data was mixed as to meeting the district benchmark at two of the schools studied; one of the schools had lower-than-desired scores. The implications of this study showed that punitive measures were not necessarily the best for students. If suspensions, long-term suspensions, expulsions, or alternative education schools worked, then we would see less students being referred to these extreme measures of discipline. In fact, more students are being referred for punishment.

Description
This study explores the impact of feedback and feedforward and personality on computer-mediated behavior change. The impact of the effects were studied using subjects who entered information relevant to their diet and exercise into an online tool. Subjects were divided into four experimental groups: those receiving only feedback, those receiving only feedforward, those receiving both, and those receiving none. Results were analyzed using regression analysis. Results indicate that both feedforward and feedback impact behavior change and that individuals with individuals ranking low in conscientiousness experienced behavior change equivalent to that of individuals with high conscientiousness in the presence of feedforward and/or feedback.
