Development Of A Resource Manual For Working With Latino Parolees, Abner Flores Jan 2021

Development Of A Resource Manual For Working With Latino Parolees, Abner Flores

Theses and Dissertations

The standard psychological treatment available for Latino men who are newly released from prison has remained unchanged for over thirty years and focuses on decreasing recidivism through cognitive-behavioral interventions by managing and decreasing law-breaking behaviors. However, clinical experience with inmates suggests that personal experiences, cultural values, and intergenerational trauma along with the long-term impact of poverty, gang ties, and repeated incarceration will all influence post-release behavior. Understanding these areas could help draw out protective factors and innate resiliency, therefore informing treatment and helping newly released inmates from becoming repeat offenders. In this dissertation, I developed a resource manual for service …

A Systematic Review Of The Literature On Post-Traumatic Growth In Police Officers After Exposure To Potentially Traumatic Events, Michael Norfleet Jan 2021

A Systematic Review Of The Literature On Post-Traumatic Growth In Police Officers After Exposure To Potentially Traumatic Events, Michael Norfleet

Theses and Dissertations

As police departments and officers across the world take on the task of reducing crime and enhancing public safety, their jobs entail the potential of exposure to events that may be experienced as traumatic. In contrast to the larger literature on negative outcomes of potentially traumatic events (PTEs), there is limited knowledge on the potential for post-traumatic growth (PTG) and how clinicians can promote it, generally and in police officers (Westphal & Bonanno, 2007). Tedeschi and Calhoun (1996), “coined the term posttraumatic growth to describe the experience of positive changes that occur as a result of the struggle with major …

Understanding The New Wealthy: Ideologies, Consumption Patterns, And Organizational Strategies For A New Generation Of High-Net Worth Individuals, Ana Brant Jan 2021

Understanding The New Wealthy: Ideologies, Consumption Patterns, And Organizational Strategies For A New Generation Of High-Net Worth Individuals, Ana Brant

Theses and Dissertations

Despite the fact that the Ultra High-Net Worth (UHNWI) belong to the wealthiest, most powerful, and influential group of consumers in the society, and nearly 70% created wealth on their own, current marketing approaches fail to consider what drives consumption behavior of this group of consumers and how can brands maximize their socio-economic impact. Across two studies, I develop a model that guides theory and practice regarding this consumer group. The first part of the first study deployed netnography and grounded theory to understand the ideologies of 30 self-made UHNWI derived from self-presentation on 3,393 Instagram posts. To ensure self-made …

The Effects Of Moral Personality, Moral Identity, Ethical Ideology, And Justice Perceptions On Workplace Deviance: A Moderated-Mediation Study, S. Blair Franklin

Theses and Dissertations

The agility, productivity, and financial success of companies depends largely on the quality of their human capital. Employee misbehaviors targeting the organization and individual colleagues leads to poor performance, bad attitudes, and an eroding corporate culture. While hundreds of studies have examined independent effects of moral personality, moral identity, ethical ideology, and organizational justice perceptions on workplace behavior, this is the first offering a moderated-mediation model to collectively explain deviant workplace behavior. The goals of this study were twofold. First, it sought to provide a more comprehensive understanding of how moral and ethical traits combine with state-based perceptions of organizational …

Spatial Cognitive Ability Is Associated With Transitory Movement Speed But Not Straightness During The Early Stages Of Exploration, Christine E. Beardsworth, Mark A. Whiteside, Lucy A. Capstick, Philippa R. Laker, Ellis J.G. Langley, Ran Nathan, Yotam Orchan, Sivan Toledo, Horik Jo Van, Joah R. Madden

School of Biological and Marine Sciences

Memories about the spatial environment, such as the locations of foraging patches, are expected to affect how individuals move around the landscape. However, individuals differ in the ability to remember spatial locations (spatial cognitive ability) and evidence is growing that these inter-individual differences influence a range of fitness proxies. Yet empirical evaluations directly linking inter-individual variation in spatial cognitive ability and the development and structure of movement paths are lacking. We assessed the performance of young pheasants ( Phasianus colchicus ) on a spatial cognition task before releasing them into a novel, rural landscape and tracking their movements. We quantified …

Evaluating Lamp Assays For Detection Of Phytoplasmas Classified In Different Ribosomal Groups, Naofel Aljafer, Mathew Dickinson Jan 2021

Evaluating Lamp Assays For Detection Of Phytoplasmas Classified In Different Ribosomal Groups, Naofel Aljafer, Mathew Dickinson

School of Biological and Marine Sciences

A new set of loop-mediated isothermal amplification assays was developed for detection of phytoplasmas associated with plant diseases and optimised for rapid laboratory detection. This set of assays was designed based on the leucyl tRNA synthetase gene expressed in most of the phytoplasmas and showing a good level of sequence divergence among strains from different 16Sr groups. This makes it a good target for developing discrete assays that can detect specific phytoplasma 16Sr groups. In this study, unique sets of LAMP assays were designed and validated for seven phytoplasma ribosomal groups (16SrI, 16SrII, 16SrIII, 16SrV, 16SrVI, 16SrX, and 16SrXII). These …

How Consistent Are Estimates Of Roughness Parameters On A Rough Coral Reef?, M Lindhart, Sg Monismith, A Khrizman, D Mucciarone, R Dunbar Jan 2021

How Consistent Are Estimates Of Roughness Parameters On A Rough Coral Reef?, M Lindhart, Sg Monismith, A Khrizman, D Mucciarone, R Dunbar

School of Biological and Marine Sciences

Coral reefs are hydrodynamically rough, creating turbulent boundary layers that transport and mix various scalars that impact reef processes and also can be used to monitor reef health. Often reef boundary layer characteristics derived from a single instrument are assumed to accurately represent the study site. This approach relies on two assumptions: first, that the boundary layer is relatively homogeneous across the area of interest, and second, that two instruments displaced in space or with different spatiotemporal resolution would produce similar results when sampling the same flow. We deployed four velocimeters over a 15 × 20 m reef at 10 …

Biological Constraints On Neural Network Models Of Cognitive Function, Friedemann Pulvermüller, Rosario Tomasello, Malte R. Henningsen-Schomers, Thomas Wennekers Jan 2021

Biological Constraints On Neural Network Models Of Cognitive Function, Friedemann Pulvermüller, Rosario Tomasello, Malte R. Henningsen-Schomers, Thomas Wennekers

School of Engineering, Computing and Mathematics

Neural network models are potential tools for improving our understanding of complex brain functions. To address this goal, these models need to be neurobiologically realistic. However, although neural networks have advanced dramatically in recent years and even achieve human-like performance on complex perceptual and cognitive tasks, their similarity to aspects of brain anatomy and physiology is imperfect. Here, we discuss different types of neural models, including localist, auto-associative, hetero-associative, deep and whole-brain networks, and identify aspects under which their biological plausibility can be improved. These aspects range from the choice of model neurons and of mechanisms of synaptic plasticity and …

A Sph Model With Open Relaxation Boundary For Wave Generation And Absorption, G Zhu, J Hughes, S Zheng, D Greaves

School of Engineering, Computing and Mathematics

In this paper, a numerical wave tank with open relaxation boundaryfor wave simulation is presented under the framework of weakly compressible Smoothed Particle Hydrodynamics (SPH). The open relaxationboundary consists of open boundaries and relaxation particles. A relaxation function is applied for the relaxation particles which are placed between the inflow/outflow zone and the fluid domain. Open particles lie inthe inflow/outflow regions to avoid kernel truncation. The open particlesand relaxation particles can be created and deleted depending on the fluidmotion around the open boundaries, and the properties of these particlescan be obtained from theoretical resolution or by extrapolating withinthe domain. The …

A Novel Method Based On Long Short Term Memory Network And Discrete-Time Zeroing Neural Algorithm For Upper-Limb Continuous Estimation Using Semg Signals, Yuanyuan Chai, Keping Liu, Chunxu Li, Zhongbo Sun, Long Jin, Tian Shi Jan 2021

A Novel Method Based On Long Short Term Memory Network And Discrete-Time Zeroing Neural Algorithm For Upper-Limb Continuous Estimation Using Semg Signals, Yuanyuan Chai, Keping Liu, Chunxu Li, Zhongbo Sun, Long Jin, Tian Shi

School of Engineering, Computing and Mathematics

In this paper, a novel closed-loop model based on surface electromyography (sEMG) comprised a long short term memory (LSTM) network and discrete-time zeroing neural algorithm called zeroing neural network (ZNN), which is developed to estimate joint angles and angular velocities of human upper limb with joint damping. The dynamic model of human upper limb with joint damping is set up as the initial equation. Then, the LSTM network is proposed as an open-loop model which described the input-output relationship between the sEMG signals and joint motion intention. Besides, a novel closed-loop model is built via ZNN for eliminating the predicted …

Complex Relationships Between Water Discharge And Sediment Concentration Across The Loess Plateau, China, Haiyan Zheng, Chiyuan Miao, Juying Jiao, Alistair G.L. Borthwick

School of Engineering, Computing and Mathematics

Understanding of the relationship between water discharge (Q) and suspended sediment concentration (SSC) across the Loess Plateau is a prerequisite for evaluating different soil and water conservation measures. Using daily Q and SSC datasets, this study jointly analyzes changes in Q and SSC on the central Loess Plateau, a major sediment-producing area of China, during the periods 1971-1987 (P1) and 2008-2016 (P2). The results show that during both P1 and P2, the contributions of maximum-3-day-per-year sediment load (SSL) to the total SSL are almost invariably over 50% (dominant), with the majority increasing further between P1 and P2. The contribution of …

Ergodic Sampling Of The Topological Charge Using The Density Of States, Guido Cossu, David Lancaster, Biagio Lucini, Roberto Pellegrini, Antonio Rago Jan 2021

Ergodic Sampling Of The Topological Charge Using The Density Of States, Guido Cossu, David Lancaster, Biagio Lucini, Roberto Pellegrini, Antonio Rago

School of Engineering, Computing and Mathematics

AbstractIn lattice calculations, the approach to the continuum limit is hindered by the severe freezing of the topological charge, which prevents ergodic sampling in configuration space. In order to significantly reduce the autocorrelation time of the topological charge, we develop a density of states approach with a smooth constraint and use it to study SU(3) pure Yang Mills gauge theory near the continuum limit. Our algorithm relies on simulated tempering across a range of couplings, which guarantees the decorrelation of the topological charge and ergodic sampling of topological sectors. Particular emphasis is placed on testing the accuracy, efficiency and scaling …

School of Engineering, Computing and Mathematics

The measurement of wave forces acting on marine structures is a complicated task, both during physical experiments and, even more so, in the field. Force transducers adopted in laboratory experiments require a minimum level of structural movement, thus violating the main assumption of fully rigid structure and introducing a dynamic response of the system. Sometimes the induced vibrations are so intense that they completely nullify the reliability of the experiments. On-site, it is even more complex, since there are no force transducers of the size and capacity able to measure such massive force intensity acting over the very large domain …

Talin Mechanosensitivity Is Modulated By A Direct Interaction With Cyclin-Dependent Kinase-1, Rosemarie E. Gough, Matthew C. Jones, Thomas Zacharchenko, Shimin Le, Miao Yu, Guillaume Jacquemet, Ste P. Muench, Jie Yan, Jd Humphries, Claus Jørgensen, Mj Humphries, Benjamin T. Goult

Peninsula Medical School

Talin (TLN1) is a mechanosensitive component of adhesion complexes that directly couples integrins to the actin cytoskeleton. In response to force, talin undergoes switch-like behavior of its multiple rod domains that modulate interactions with its binding partners. Cyclin-dependent kinase-1 (CDK1) is a key regulator of the cell cycle, exerting its effects through synchronized phosphorylation of a large number of protein targets. CDK1 activity maintains adhesion during interphase, and its inhibition is a prerequisite for the tightly choreographed changes in cell shape and adhesion that are required for successful mitosis. Using a combination of biochemical, structural, and cell biological approaches, we …
