Previous research indicates that difficulties in emotion regulation and greater dissociation from one's emotions are often observed among trauma survivors. Further, trauma survivors often show greater negative emotions such as anger, and diminished positive emotions such as happiness. Relatively less is known about the relationship between posttraumatic stress symptoms, dissociation, emotion regulation difficulties, and non-trauma related emotional experiences in daily life. This study examined whether greater reports of posttraumatic stress symptoms, difficulties in emotion regulation, and dissociative tendencies were associated with greater intensity of anger and lower intensity of happiness during a relived emotions task (i.e., recalling and describing autobiographical memories evoking specific emotions). Participants were 50 individuals who had experienced a traumatic event and reported a range of posttraumatic stress symptoms. Participants rated how they felt while recalling specific emotional memories, as well as how they remembered feeling at the time of the event. Results showed that dissociative tendencies was the best predictor of greater intensity of anger and, contrary to the hypothesis, dissociative tendencies was predictive of greater happiness intensity as well. These findings are consistent with previous research indicating a paradoxical effect of heightened anger reactivity among individuals with dissociative tendencies. In addition, researchers have argued that individuals with a history of traumatization do not report lower positive emotional experiences. The present findings may suggest the use of dissociation as a mechanism to avoid certain trauma related emotions (e.g, fear and anxiety), in turn creating heightened experiences of other emotions such as anger and happiness.

Description
The research on female juvenile gang members is limited in scope and research has not yet examined mental health issues in this population. This study examines the case histories of 127 female juvenile gang members who were arrested by the Florida Department of Juvenile Justice. To add to the limited gender-specific research on female juvenile gang members, data are presented regarding this population's mental health problems, childhood maltreatment, substance abuse problems, age of contact with the juvenile justice system, and other factors salient to female juvenile gang members' prevention, treatment, and intervention needs. Female juvenile gang members who had a mental health diagnosis were significantly more likely to report childhood maltreatment. Female juvenile gang members who were younger at their age of first arrest were significantly more likely to report chronic substance use. Clinical levels of anger-irritability and depression-anxiety were found for approximately half of female juvenile gang members and suicide ideation was found for approximately one fourth. These findings have important implications for practitioners and gender-specific prevention, intervention, and treatment programs targeted specifically for female juvenile gang members.

Description
Patriarchal forces manifest in a variety of wide-reaching ways, but few are more potent then the methods by which patriarchy becomes embodied and integrated into patterns of emotional expression. This is particularly true to the boundaries of anger expression for women which are placed upon and reinforced through patriarchal socialization. This thesis explores the relationship between gender socialization, the construction of happiness, and resistance through anger expression. Drawing from Sarah Ahmed's The Promise of Happiness and Judith Butler's Gender Troubles, this project first identifies the construction of subjecthood for women, focusing particularly on the ways in which performance of gendered categories becomes necessary to intelligibility as a subject. Through an exploration of current social science research, this project then seeks to answer the ways in which the theoretical notion of gendered subjecthood comes to function within tangible expressions, or lack of expression, of anger. Finally, this thesis explores what it may mean for women to create a healing relationship with anger, forcibly creating space for expansive subjecthood.

Description
The objective of this study is to determine if female attorneys are penalized for expressing anger, while male attorneys gain influence when they express anger. I hypothesized that angry male attorneys would be perceived as having more positive traits and less negative traits than calm male attorney. In contrast, I hypothesized that angry female attorneys would be perceived as having more negative traits and less positive traits than calm female attorneys. I hypothesized that, as a result, participants would be more likely to hire the angry male attorney than the calm male attorney, while they would be less likely to hire the angry female attorney than the calm female attorney. After having participants view a video of attorneys giving closing arguments, whether it be angry or calm, male or female and having them answer questions, I found that both attorneys were characterized as having both more positive and negative traits than calm attorneys—regardless of their gender. In regards to the likelihood of being hired, I found that angry male attorneys were more likely to be hired than calm male attorneys. In contrast, angry female attorneys were less likely to be hired than calm female attorneys. Thus, although participants found both male and female angry (versus calm) attorneys high on negative and positive characteristics, they were more likely to hire the angry (versus calm) male attorney, which is consistent with previous research showing men are seen as more competent when expressing anger. These data suggest that there might be a systematic bias against women who try to exert influence in the courtroom by expressing anger.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
This longitudinal study examines the relations of anger, gender, and intrusive maternal parenting to empathy in toddlers. Participants (247 toddlers at the initial assessment) were assessed in a laboratory at approximately 18 (T1, N = 247), 30 (T2, N = 216), and 42 (T3, N = 192) months of age. Toddlers' observed anger was measured during a toy removal task and maternal intrusiveness was observed during free play between mother and toddler. Reported empathy was measured using questionnaires completed by mothers and fathers. At 18 months, a positive relation between observed anger and reported empathy was found for boys, but not for girls. At 30 months, maternal intrusiveness positively predicted empathy in boys, but it negatively predicted empathy in girls. These findings provide insight about sex differences in the development of empathy and concern for others in early childhood.

Description
We used archival data to examine the predictive validity of a pre-release violence risk assessment battery over six years at a forensic hospital (N=230, 100% male, 63.0% African-American, 34.3% Caucasian). Examining “real world” forensic decision-making is important for illuminating potential areas for improvement. The battery included the Historical-Clinical-Risk Management-20, Psychopathy Checklist-Revised, Schedule of Imagined Violence, and Novaco Anger Scale and Provocation Inventory. Three outcome “recidivism” variables included contact violence, contact & threatened violence, and any reason for hospital return. Results indicated measures of general violence risk and psychopathy were highly correlated but weakly associated with reports of imagined violence and a measure of anger. Measures of imagined violence and anger were correlated with one another. Receiver Operating Characteristic curve analyses revealed, unexpectedly, that none of the scales or subscales predicted recidivism better than chance. Multiple regression indicated the battery failed to account for recidivism outcomes. We conclude by discussing three possible explanations, including timing of assessments, controlled versus field studies, and recidivism base rates.

Description
There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity
for Unmanned Aerial Vehicles.
Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.

Description
So far, love and desire have preoccupied scholarly inquiries into the emotional landscape in late imperial China. However, the disproportional focus diminishes the complexity and interdisciplinarity of the emotional experiences during this period. Alternatively, this dissertation seeks to contextualize the understudied emotion of anger and uses it as a different entry point into the emotional vista of late imperial China. It explores the stimuli that give rise to anger in late imperial Chinese fiction and drama, as well as the ways in which these literary works configure the regulation of that emotion. This dissertation examines a wide range of primary materials, such as deliverance plays, historical romance, domestic novels, and so forth. It situates these literary texts in reference to Quanzhen Daoist teachings, orthodox Confucian thought, and medical discourse, which prescribe the rootedness of anger in religious trials, ritual improprieties, moral dubiousness, and corporeal responses. Simultaneously, this dissertation reveals how fiction and drama contest the presumed righteousness of anger and complicate the parameters construed by the above-mentioned texts through editorial intervention, paratextual negotiation, and cross-genre adaptation. It further teases out the gendering of anger, particularly within the discourse on the four obsessions of drunkenness, lust, avarice, and qi. The emotion’s gendered dimension bears upon the approaches that literary imagination adopts to regulate anger, including patience, violence, and silence. The body of either the angry person or the target of his or her fury stands out as the paramount site upon which the diverse ways of coping with the emotion impinge. Ultimately, this dissertation enriches the current understanding of the emotional experiences in late imperial China and demonstrates anger as a prominent nodal point upon which various strands of discourse converge.
