Development and Confirmatory Factor Analysis of the Non‐Violent and Violent Offending Behavior Scale (NVOBS)

both male and female participants in general (non‐forensic) samples. Potential items were selected from existing measures. A sample of 653 British university students completed all items, and their responses were analyzed using exploratory factor analysis and validated with confirmatory factor analysis. There were five separate factors (general violence, drug‐related offenses, partner violence, theft, and criminal damage), which were confirmed with acceptable fit indices. The five‐factor model applied to both males and females. Each subscale demonstrated good internal consistency, with alphas for each factor ranging from moderate to good. This new measure is a potentially valuable research tool for investigating people’s involvement in violent and non‐violent offending. The importance of examining the psychometric properties of scales, and confirming the category groupings using CFA of the items is outlined

To provoke intrigue using simplified, whimsical, playful (toy-like) forms with recycled materials that convey complex, possibly dark, relationships to foster a curiosity of innocence lost and deliver a deeper meaning (Archer, 2012). To me life is an exercise in exploring the human condition; specifically relationships. From the day we arrive we establish relationships with everything in our world, even before we arrive, if we count the ten months of uterine swimming. The sights, sounds, and touch of lights, voices, and caress all play a part in our connection to the world. My thesis work focuses on the connections among interpersonal relationships, childhood, and natural cycles. My use of the term `interpersonal relationships\u27 refers to more intimate relationships, like family and good friends, rather than referring to casual acquaintances, like the bank teller or the coffee shop barista. For me, the meaning of natural cycles is the ability to grow and/or decay. Relationships and steel share the idea of natural cycles. A relationship may grow, then through lack of attention fade away. The same holds true for steel. Without care and protection, steel will rust and decay. The art work reflects these themes and how I have made them into lasting configurations. The goal of my thesis is to explore and examine interpersonal relationships through child-like figures that express natural cycles in the human experience. Metal sculptures utilizing recycled, surplus, and up-cycled materials illustrating past or current associations in order to obtain a better understanding of special connections. Urban Dictionary\u27s definition of up-cycled is; using ordinary objects to make something extraordinary (Up-cycle, n. d.) I produced compositions that suggest the figure, or objects, while translating personal relationships for the viewer. Once encountered, the physical manifestations create a forced visual dialogue to which the audience could respond to and possibly question. With reflection, the audience may examine themselves through the work, possibly sparking a relationship or childhood memory of their own that the art draws out in them. My challenge was to physically manifest these mostly intangible intimate relationships and childhood memories. Using figures, or compositions that suggest the body and objects, I help the viewer by interpreting and translating the relationships into forms that interacted with the audience. By constructing a physical as well as visual dialogue between viewer and form, the objective is to stir-up intrigue and to promote self-examinations of our experiences and our relationships

A numerical study of laminar to turbulent evolution and free-surface interaction of a vortex ring

Direct numerical simulation was used to study various aspects of vortex ring evolution and interaction with a free surface. An investigation of a single unbounded vortex ring at various Reynolds numbers and core thicknesses showed qualitative differences between the evolution of thin- and thick-core rings, leading to a correction factor to the classical equation for the ring translational velocity. The obtained linear modal growth rates were compared with previous work, highlighting the role of the wake in triply periodic numerical simulations. The transition from a laminar to a turbulent ring is marked by the rearrangement of the outer core vorticity into a clearly defined secondary structure. The onset of the fully turbulent state is associated with shedding of the structure in a series of hairpin vortices. A Lagrangian particle analysis was performed to determine the ring entrainment and detrainment properties and to investigate the possibility of an axial flow being generated around the circumference of the core region prior to the onset of turbulence.The orthogonal interaction of laminar, transitional and turbulent rings with an initially undisturbed free surface was investigated. At small depths, the expanding ring is unstable to the Crow instability but its dominant mode is predetermined by the prior development of the Widnall instability. The presence of opposite-signed vorticity, due to surface curvature, affects the ring dynamics at the surface. The interaction of a transitional ring modifies the surface displacements, reflecting the structure of the ring below. The secondary structure associated with a transitional ring reconnects to the surface in addition to the inner core. In the presence of the surface, the turbulent ring finds greater coherency of the core due to stretching and aligning of vorticity filaments. The addition of a planar surface wave field modified the ring interaction greatly due to the higher surface curvature and associated surface vorticity. The ring expands asymmetrically and even rebounds locally if sufficient opposite-signed vorticity is generated. The ring diffracts the surface wavefield and the generation of secondary small-amplitude waves was noted

A transputer based implementation of a quick look processor for an airborne SAR system

Includes bibliographical references.The purpose of this thesis is to describe the development of a transputer based real-time Synthetic Aperture Radar (SAR) processor called the Quick Look Processor (QLP). The QLP is required to produce medium resolution, real-time images at a wavelength of 2.5m for the airborne South African SAR (SASAR) system which is under development at the University of Cape Town (UCT). The required azimuth resolution for the QLP is 30m and system is required to process 2048 range bins at a rate of 39 range lines per second. The algorithm used was developed at UCT, and works on the principle of dividing up the synthetic aperture into subapertures with appropriate phase corrections. This method is used in order to reduce computational loading (for real-time processing), but at the same time achieve medium resolution processing. One of the fundamental issues concerning this algorithm is its efficiency as the required azimuth resolution is increased. The system is designed around a host PC and a network of nine transputers. The host PC communicates with the other SASAR subsystems via an Ethernet network. It is responsible for displaying and saving the SAR image, receiving and displaying geocoding information and configuring the transputer network. The transputer network is responsible for processing the SAR data. The network is connected in a pipeline configuration with a master transputer controlling the other eight slave transputers. Each slave transputer concurrently processes a section of the swath width. This method allows for easy scalability
