Several questionable officer involved shootings and perceived abuses of authority disproportionately involving minority citizens have resulted in public outcry, protests, and nationwide scrutiny of police in recent years. The resulting police legitimacy crisis has prompted agencies to rapidly equip officers with body-worn video cameras (BWCs). BWC advocates lauded the findings of an early study that attributed significant reductions in use of force incidents and citizen complaints to the devices and it is this and a handful of other short-term studies upon which the claims of these benefits are predicated. However, subsequent research has produced mixed findings and the sustainability of any reductions remains questionable. The limited knowledge concerning the impact of BWCs on the aforementioned outcomes is problematic considering the potential negative impact of unrealistic expectations and the expense of BWC program maintenance. The objective of this dissertation is to address gaps in the extant research by exploring the impact of an incremental deployment of the devices on the frequency and severity of use of force incidents and the frequency and outcome of citizen complaints while controlling for staffing, volume of officer-initiated enforcement contacts, and the Ferguson incident. Utilizing 86-months of secondary data collected from the Newport News, Virginia Police Department (NNPD) a vector autoregressive multivariate time series analysis indicates that BWCs were a significant factor in a substantial sustained reduction in use of force and a substantial sustained increase in exonerated complaint dispositions at the NNPD.

Increasing urbanization in the US is leading to development or re-development of lands adjacent to solid waste facilities and these lands are being considered for residential communities and commercial projects. Thus, the potential for nuisance complaints against the pre-existing solid waste facility operations has become an increasing reality. The objective of this study was to develop a methodology to gather scientific and quantifiable data related to potential nuisances caused by landfills to determine setbacks and buffer zones near landfill and transfer station operations. Appropriate recommendations for these setbacks were made from case studies conducted at two landfills in Florida. The study involved making measurements related to odor, noise, litter and dust. Impact on housing prices was also evaluated by analyzing publicly available house price data. In this study volatile organic compound (VOC) concentration was used as a surrogate measure for gaseous impacts. The mass flux of VOCs was measured on the landfills using the dynamic flux chamber method. The ultimate purpose of flux measurements was to provide input data for dispersion modeling to analyze the extent of odor impact around the landfills, which is outside the scope of this study. Ambient measurements were also made around Landfill A for validating the dispersion model. Although there are no significant health and odor impacts caused by the landfill, higher background concentration extend 1.2-1.5 km from the landfill center on the Southeast side of the landfill. Litter from the road sides around the landfills was collected and catalogued based on size and material type. Litter count per site obtained for both landfills was less than the 2001 and 2002 state-wide counts. The difference was statistically significant. Noise measurements were made at landfills during incineration and landfilling. Based on average measurements (Leq) obtained at various distances from WTE facility and landfilling activity, and considering EPA recommended noise level of 55 dB(A) for a quiet neighborhood, a set back distance of 1.6-1.9 km was recommended. Impact on house prices near the landfills was done for four landfills in Florida. Analysis showed that three out of four landfills had significantly impacted the house price within 0.6-0.8 km from the edge of the landfill. Dust measurements were made at Landfill B using particulate samplers, quantifying the dust associated with landfilling. Measured values were below National Ambient Air quality Standard (NAAQ) for PM10. Finally, recommendations were developed to mitigate some of these nuisances

This study investigated the effects of gender, both patient and physician, on how a medical complaint is perceived and acted upon by health professionals. A 2 x 2 factorial design was used, with gender of physician and patient as the two factors, respectively. The participants were physicians (M.D.s) who were recruited by approaching local hospitals/clinics and requesting their participation in the research. They were asked to respond to a patient vignette and a questionnaire assessing the physician's beliefs about and intentions toward the patient. Using a 2 x 2 ANOVA with a specified .05 significance level, no statistically significant differences were found in the assessment of the perceived seriousness of a medical complaint, in the aggressiveness of the work-up provided, and in the diagnoses given to patients. The findings from this study are of value in exploring the existence of gender bias in the medical setting. The absence of gender bias, as it occurred in this study, is an encouraging finding for members of the health care community.

Aim: The aim of the study was to explore the association between school pressure and psychosomatic health complaints and the potentially moderating effect of physical activity in a Swedish cohort of adolescents.Method: Cross-sectional data from the Swedish Health Behavior in School-aged Children (HBSC) survey of 2017/2018 was used, with participants aged 11-15 (n=3,745). The exposure was school pressure, which was measured with one question. The outcome was psychosomatic complaints, with information on the frequency of eight complaints which was added to an index. Physical activity was measured with one question. Covariates were gender, grade, and family affluence. First, Cross-tabulations with Chi squared tests were performed to examine patterns related to the exposure variable, school pressure and the covariates as well, and one- way ANOVA was used to explore the bivariate association between school pressure and psychosomatic complaints. Next, linear regression analyses were conducted to examine the association between school pressure and psychosomatic health complaints, with adjusted models including age, gender, familial socioeconomic status, and physical activity. Moderation was examined with a multiplicative interaction term which was evaluated with a Wald test, as well as with a combined variable of both school pressure and physical activity.  Results: The results suggest that higher levels of school pressure were significantly associated with higher levels of psychosomatic health complaints. The association persisted even after the adjustment for covariates. The interaction analyses did not present any moderating effect of physical activity. However, the combined variable analysis showed indications of a buffering effect: for students in the high school pressure group, those with low physical activity had more psychosomatic health complaints than those with high physical activity, the difference being statistically significant.  Conclusion: This study helps further the knowledge on how adolescents’ experiences of school pressure is associated with psychosomatic health complaints and how physical activity can buffer against this association. Suggestions on future research and important study strengths and limitations were discussed.

Researchers have argued that a reason for non-medical use of prescription psychostimulants is to self-medicate an undiagnosed case of ADHD. Therefore, this study examined neuropsychological complaints in college students with and without a history of prescription psychostimulant use. College students (N = 615) completed an Internet-based survey assessing behaviors associated with prescription psychostimulant use and symptoms of neuropsychological impairment. The results of the current study support the hypothesis that college students who non-medically use prescription psychostimulants report more symptoms of cognitive impairment (i.e., memory and attention complaints) than college students classified as non-users. Complaints about memory and attention were as common in non-medical users as medical users. Overall, the results suggest that non-medical users may use prescription psychostimulants due to perceived symptoms of ADHD.

Objective: This study examined (a) the distribution of physical symptoms in youth with specific primary anxiety disorders (i.e. separation anxiety disorder [SAD], generalized anxiety disorder [GAD], and social phobia [SP]) and (b) their response to treatment with cognitive-behavioral therapy (CBT; 14 sessions of CBT over the course of 12 weeks), medication, combination therapy (CBT + medication), or pill placebo in a sample. Method: Anxiety disordered youth (N = 488, age 7-17) who met criteria for a primary diagnosis of GAD, SAD, and/or SP as part of the Child/Adolescent Anxiety Multimodal Study (CAMS; Walkup et al. 2008) were included in this study. The sample was diverse and included children with comorbid secondary diagnoses. Results: The most common somatic complaints were headache, stomach pain or aches, feeling drowsy or too sleepy, head cold or sniffles, and sleeplessness. The distribution of these complaints did not differ across diagnostic groups. The number and severity of physical symptoms decreased over the course of treatment. Treatment condition, including placebo, was unrelated to the number and severity of physical symptoms posttreatment. Conclusions: Treatment of anxiety leads to a decrease in the number and severity of physical symptoms experienced in anxiety-disordered youth, irrespective of treatment type. / Psychology

La présente étude s’intéresse aux facteurs associés aux différents types de décisions rendus par le Comité à la déontologie policière du Québec. Pour ce faire, 267 jugements rendus entre 2009 et 2013 sont analysés. La régression logistique est utilisée pour déterminer les facteurs associés (1) à la décision de culpabilité (2) à la décision sur sanction et (3) à la sévérité de la sanction (sanction de courte durée ou de longue durée). Les facteurs utilisés dans les modèles sont des facteurs légaux (nature, gravité de l’inconduite et plaidoyer de culpabilité) ainsi que des facteurs extra-légaux -tels que les caractéristiques des policiers et des plaignants, le contexte de l’intervention ainsi qu’un facteur lié au processus décisionnel du comité (la durée des procédures)- disponibles dans les jugements. Les résultats montrent que le verdict est majoritairement influencé par la qualité de la preuve et que la sévérité de la sanction dépend principalement des facteurs légaux. Toutefois, certains facteurs extra-légaux influencent le verdict, dont le grade du policier. Parmi les facteurs extra-légaux qui influencent la décision sur sanction, il y a le grade, le sexe et le service de police du policier. Malgré tout, le Comité à la déontologie policière prend des décisions relativement cohérentes et les décisions prises sont justifiables légalement sauf pour quelques caractéristiques du policier et pour la durée des procédures. Ces derniers montrent la nécessité de faire davantage d’études sur le sujet. / Even though disciplinary systems are criticized for their lack of coherence and fairness, there is currently no study specifically focusing on the predictive factors related to the outcome of the officers’ sentencing process. The present research aims to investigate the factors associated with the different types of decisions rendered by the Deontology Committee of Quebec. A total of 267 hearings were analyzed between the year 2009 and 2013. Logistic regression models are used to predict the outcomes of the sentencing on three levels: (1) the determination of guilt, (2) the decision on the sanction, and (3) the severity of the sanction (short- or long-term sanction). The factors used in the models are legal factors - specific to the nature and the severity of the misconduct - and extralegal factors - related to the complainant’s and officer’s characteristics, the situation and the length of procedures - available in the judgments handed down by the Committee. The analyses in this paper show that the different outcomes are mostly due to the legally relevant factors. On the other hand, some extralegal factors like the officers’ rank have an influence on the determination of guilt. And, some officers’ characteristics like the officers’ rank, sex, police department and the length of procedures tend to influence the outcomes of the sentencing. Thus, the findings show that decisions rendered by the Committee are mostly taken in accordance with its mandate and are legally justifiable. The latter results show that more research is needed concerning the impact of extralegal factors on the outcomes.

The reform measures recommended by the Commission of Inquiry into Possible Illegal Activities and Associated Police Misconduct (referred to as the "Fitzgerald Inquiry") radically transformed the face of policing in Queensland. The most significant of these recommendations was the establishment of an external oversight body, the Criminal Justice Commission (CJC), which has independence from executive government and holds the power to investigate not only police but any public servant or politician. Other recommendations included "Whistleblower" legislation, increasing sanctions for serious misconduct, lateral recruitment and promotion by merit rather than seniority. The first main research question tested in this thesis is whether these reform measures have produced improvements in the following areas: the efficiency and effectiveness of the processes for dealing with complaints against police; public confidence in those processes and the public standing of the Queensland Police Service (QPS) generally; standards of police behaviour; the incidence of corrupt conduct; and police attitudes towards reporting misconduct by their fellow officers. These Fitzgerald Inquiry reforms were strategies primarily derived from two schools of thought describing the nature and cause of police corruption: deterrence based theory (including "individual" or "rotten apple" theory) and cultural (also labeled "cultural" or "socialisation") based theory. To date most strategies used to combat police corruption have been underpinned by these theories. A third theory - situational based theory (sometimes titled "environmental" or "opportunity" theory) - which has had success in crime prevention, has been scarcely used in the area of police corruption. However, an extensive body of research has affirmed the effects of situational factors on police behaviour, suggesting the potential for the application of situational crime prevention initiatives in combatting police corruption. The second research question proposed in this thesis is whether situational based theory could also be beneficial in the prevention of police corruption. Data drawn upon to test the first research question were interviews and surveys with police officers, public attitude surveys and statistics from the processing of complaints against police. Although each source has limitations, collectively the data are sufficiently comprehensive - and robust - to defend conclusions about the general direction of the changes which have occurred. These data indicate that the Fitzgerald Inquiry reforms have, at least to some degree, had their intended impact on the QPS. These reforms have contributed to an apparent improvement in public confidence in the complaints system and the QPS generally. Moreover, the available evidence suggests that the Fitzgerald Inquiry reforms have resulted in a weakening of the police code of silence. As far as the specific issue of corruption in the QPS is concerned, it is difficult to draw firm conclusions from existing data sources. However, the weight of the available evidence is that such conduct is less pervasive and occurs at lower levels than was the case in the pre-Fitzgerald Inquiry QPS. It is very difficult to ascertain which reform components were the most effective and which were not helpful at all, as these reform measures were initiated simultaneously. For example, the negative elements of the police culture may have been eliminated or reduced but whether it was the cultural strategies or one of the deterrence based strategies influencing officer behaviour remains unknown. The second main research question the thesis poses is that the use of situational crime prevention techniques has potential for contributing to the prevention of police corruption. A situational analysis of complaints against police data, including the development of a typology for classifying types of police corruption and misconduct, was used as an example of how this may be accomplished in Queensland. The study provides some, albeit limited, support for the hypothesis that situational crime prevention methods are applicable to police corruption. Based upon three years of complaints data, enough homogenous cases were gathered to enable the analysis of four categories of police corruption - Opportunistic Thefts, Driving under the Influence, Assault (while off-duty), and Theft from Employer. Given that this study only used three years of complaints data held by the CJC and more than nine years of data exist, productive situational analyses of many other categories of corruption is probable. This study also illustrated that complaints against police data are being under utilised by the QPS and the CJC. For future research in the situational analysis of complaints data, I recommend improving the gathering of data from complaints files for storage in electronic form to enable situational prevention analysis to be conducted more readily. A geographical example was used to illustrate further how complaints against police data could be more extensively utilised as a prevention tool. This analysis was conducted at an organisation unit level determined primarily by geographical factors. The complaint patterns of units of similar "task environments", as measured by unit size and type of duties performed, were compared in an attempt to identify those units experiencing the presence or absence of "bad apples" or a "negative culture". This study led to the conclusion that a divisional analysis of complaints data can provide information valuable in combatting police corruption. When task environment was held constant, it was possible to identify units experiencing the effects of possible "bad apples" and/or "negative cultures". Once these particular units were identified, intervention strategies to address the units' particular problem could be constructed. Future research in this area would involve ongoing divisional data analysis followed-up by individual assessment of officers identified as "bad apples", or a "compare-and-contrast" procedure to distinguish features requiring correction in units identified as having a "negative culture". The research findings presented in this thesis are that progress has occurred in a number of areas in addressing the problems identified by the Fitzgerald Inquiry, but that there is undoubtedly scope for more to be achieved. Despite the very significant increase in the resources and powers available to investigators post-Fitzgerald, it is still difficult to prove that a police officer engaged in misconduct, or that other officers were aware of this fact and had failed to take action, because of the constraints imposed by evidentiary and legal requirements. Thus, while it is vital to maintain an effective and credible independent complaints investigation system and ensure that there is a proper internal discipline process in place, the scope for increasing the "deterrent power" of the present system is limited. Putting more resources into complaints investigations might make a difference at the margins, but is unlikely to lead to a significant increase in the probability of a complaint being substantiated and a sanction imposed. Investing more resources in investigations has an additional cost in that such resources are then lost to other efforts to combat corruption that may provide more fruitful results in the long term. The value of an occasional substantiation is placed above the ability to engage in a large amount of prevention work. Inevitably then, three clear messages are apparent. First, continued effort must be made to modify the organisational climate of the QPS in terms of commitment to integrity. Recommended strategies to accomplish this end are to continue the recruitment of more educated, female and older officers to reduce police-citizen conflict and the negative elements of the police culture, and also to develop a comprehensive, integrated approach to ethics education for QPS officers at all ranks and positions. Second, other forms of deterrence against misconduct are needed such as the use of covert strategies like integrity testing which could be conducted in conjunction with the CJC. Third, a greater emphasis needs to be placed on developing and implementing preventive strategies. This thesis has shown that valuable prevention strategies can be gained from situational and divisional analysis of complaints data, and a range of proactive management options based upon situational crime prevention theory are recommended. These strategies have application in any police service.
