Design and analysis considerations for deployment mechanisms in a space environment
On the second flight of the INTELSAT V spacecraft the time required for successful deployment of the north solar array was longer than originally predicted. The south solar array deployed as predicted. As a result of the difference in deployment times a series of experiments was conducted to locate the cause of the difference. Deployment rate sensitivity to hinge friction and temperature levels was investigated. A digital computer simulation of the deployment was created to evaluate the effects of parameter changes on deployment. Hinge design was optimized for nominal solar array deployment time for future INTELSAT V satellites. The nominal deployment times of both solar arrays on the third flight of INTELSAT V confirms the validity of the simulation and design optimization

The Compositions of Thomas Tallis: How the English Reformation Informed His Style
Thomas Tallis, known by some as the Father of English Church Music, accomplished one of the most impressive feats in the history of musical service: surviving in the Chapel Royal through the reigns of vastly different monarchs during one of the most volatile political climates in the country\u27s history. A clear streak of pragmatism shines through this stability and success, but exactly how did that pragmatism demonstrate itself within his compositional style? Through exploration and analysis of Tallis\u27s musical style in different political and religious periods, one discovers the answer to how he managed to navigate the winds of change that led to ostracization and demise for so many leaders in the flux of power. His brilliance becomes evident as the diversity and skill with which he composed allowed the music to speak to its audience in a way that was both politically acceptable and stylistically creative. Through his adaptability and keen sense, Tallis’s compositions became exemplars for the musical principles espoused in whatever period he composed within, whether it be the austere practice of the Cranmer/Edwardian period, or the decidedly more expressive works composed under Queen Mary. The fact that his music still speaks to many today shows the legacy that this titan of church composition left behind as the nimble purveyor of distinct and period defining styles in composition
AFFECTIVE INSTABILITY ACROSS DIAGNOSTIC MODELS
The National Institute of Mental Health’s (NIMH) Research Domain Criteria (RDoC; Insel et al., 2010; Sanislow et al., 2010) were established in an effort to explore underlying dimensions that cut across many existing disorders as well as to provide an alternative to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013). The present dissertation aimed to study one major component of the RDoC model, negative valence, as compared to other models hypothesized to be closely related, as well as its relationship to a key component of psychopathology, affective instability. Participants were adult community residents (N=90) currently in mental health treatment. Participants received self-report measures of RDoC negative valence, five-factor model (FFM) neuroticism, and DSM-5 Section 3 negative affectivity, along with measures of affective instability, borderline personality disorder, and social-occupational impairment. Through this investigation, a better understanding and potential expansion of this new model of diagnosis for clinicians and researchers is provided. In particular, it is suggested that RDoC negative valence is commensurate with FFM neuroticism and DSM-5 negative affectivity, and it would be beneficial if it was expanded to include affective instability
The DSM-5 Dimensional Trait Model and the Five Factor Model
The current thesis tests empirically the relationship of the dimensional trait model proposed for the fifth edition of the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders with five-factor models (FFM) of personality disorder (PD). The DSM-5 Personality and Personality Disorders Work Group proposes to diagnose the disorders largely in terms of a 25 trait dimensional model organized within five broad domains (i.e., negative affectivity, detachment, antagonism, disinhibition, and psychoticism). Consistent with the authors of DSM-5, it was predicted that negative affectivity would align with FFM neuroticism, detachment with FFM introversion, antagonism with FFM antagonism, disinhibition with low FFM conscientiousness and, contrary to the authors of DSM-5, psychoticism would align with FFM openness. Suggested changes in trait placements according to FFM of PD research were also tested. Four measures of five factor models of general personality were administered to 445 undergraduates along with the Personality Inventory for DSM-5. The results of the present study provided support for the hypothesis that all five domains of the DSM-5 dimensional trait model are maladaptive variants of general personality structure, including the domain of psychoticism; however, the findings provided mixed support for suggested trait placement changes in the DSM-5 model
Conservation Officers: A Force Multiplier for Homeland Security
Today's law enforcement officers—both conservation and police—find themselves adapting to an emerging and dynamic threat environment. Policies and practices aimed at the prevention of threats have focused primarily on federal, state, and local police agencies. At a time when terrorists, extremists, and activists have begun to widen their array of attack methods, collaboration across all sectors of law enforcement becomes essential. More specifically, an increased vulnerability to biological threats has not been met by steps to prevent or mitigate these threats. Conservation officers have a unique and integral role to enhance homeland security efforts given their day-to-day operations and interactions with the community, especially rural America. This article will discuss the role of conservation officers as it relates to homeland security—a significant conceptual component to research and practice that has largely been ignored by both academics and professionals. The integration of conservation officers into the proactive information sharing environment will be discussed to strengthen a culture of information sharing as it pertains to an “all-threats, all-hazards” philosophy and to enhance national security awareness. Moreover, this article will challenge the traditional range of threats associated with biological terrorism by providing an illustrative case study
My Religion and My People: Levels of Ingroup Identification and Christian Religious Orientations
People adopt a variety of approaches to practice their religion, but to date there has been no examination as to how identification with one’s community, with Americans, and with all humanity may relate to different religious orientations. Two studies tested the hypotheses that 1) intrinsic religious orientation would be associated with all three levels of ingroup identification, 2) extrinsic religious orientation would be associated with community-level identification only, 3) quest religious orientation would be associated with humanity-level identification only, and 4) orthodox religious orientation would be associated with community- and country-level identification only. Study 2 controlled for several individual difference variables. In both studies, participants (n = 285 for Study 1, n = 507 for Study 2) completed online surveys. The results across both studies showed that identifying with country was associated with orthodox Christianity, and identifying with all humanity was associated with intrinsic Christianity. Implications for research on religion and outgroup prejudice are discussed

Agent-based modeling and simulation for the design of the future european Air Traffic Management system: the experience of CASSIOPEIA
The SESAR (Single European Sky ATM Research) program is an ambitious re-search and development initiative to design the future European air traffic man-agement (ATM) system. The study of the behavior of ATM systems using agent-based modeling and simulation tools can help the development of new methods to improve their performance. This paper presents an overview of existing agent-based approaches in air transportation (paying special attention to the challenges that exist for the design of future ATM systems) and, subsequently, describes a new agent-based approach that we proposed in the CASSIOPEIA project, which was developed according to the goals of the SESAR program. In our approach, we use agent models for different ATM stakeholders, and, in contrast to previous work, our solution models new collaborative decision processes for flow traffic management, it uses an intermediate level of abstraction (useful for simulations at larger scales), and was designed to be a practical tool (open and reusable) for the development of different ATM studies. It was successfully applied in three stud-ies related to the design of future ATM systems in Europe
