Description
In spite of numerous legal interventions and a fairly strong legal capacity compared to other neighboring countries, Zimbabwean law enforcement and judiciary have failed to overcome Intimate Partner Violence (IPV). This research examines the role of customary law in the continued prevalence of IPV among Zimbabwean women, particularly, the subtle ways in which customary law legitimates the ideals of patriarchal domination in the communal and legal handling of IPV cases. The study utilized qualitative methodology in the form of structured interviews as well as pre-interview questionnaires. Eighteen women who identified as IPV survivors or victims were recruited using snowball sampling method whereby each person interviewed was asked to suggest additional people who were either present victims or survivors of IPV. Five lawyers from Chinhoyi, ten lawyers from Harare, ten police officers from Chinhoyi and ten police officers from Harare were identified using judgement or purposive sampling where subjects are chosen due to availability. The research established that IPV is a way in which abusers exercise their assumed patriarchal rights over women. Likewise, police officers are also influenced by attitudes and mentalities acquired from customary law in the way they handle IPV cases which resultantly leads to secondary victimization of IPV victims. The research concluded that much work still needs to be done by the judiciary, law enforcement and the community to combat the prevalence of IPV in Zimbabwe.

Description
This document accompanies new recordings of four recent sonatas for trumpet and piano. The project’s objective is to promote these works, while providing a comprehensive resource for potential performers. The four sonatas were selected based on their appeal to modern audiences. Composers Brendan Collins, Luis Engelke, William Rowson, and Christoph Nils Thompson each represents a different country, and they offer significant contributions to the trumpet repertoire. Each sonata expertly features the trumpet by highlighting its lyricism, virtuosity, and ability to cross genres.
The accompanying document draws upon interviews with the four composers, which reveal insights into the compositional process and provide details that performers will find useful. This document also offers in-depth musical descriptions, allowing performers to enhance their understanding of each sonata. The principal component of the document is the performer’s guide: Advice is presented directly to the trumpet player that has been garnered from the composers’ interviews, study of the music, and the author’s thoughts on preparing the music. To help other young musicians better comprehend the recording process, the author’s own experience is detailed. Ultimately, this document provides a window into the lifespan of the four sonatas; from their initial composition through the various stages of studying and rehearsing, culminating with the experience of recording these works for the first time.

Description
Two of the defining behaviors associated with the hominin lineage are an increased reliance on tool use and the routine incorporation of animal tissue in the diet. These adaptations have been linked to numerous downstream consequences including key physiological adaptations as well as social and cognitive effects associated with modern humans. Thus, a critical issue in human evolution is how to determine when hominins began incorporating significant amounts of meat into their diets. Bone surface modifications (BSM) have long been recognized as a powerful inferential tool in identifying the differential involvement of actors responsible for altering assemblages of bone recovered from both archaeological and paleontological contexts and remain a primary source of direct evidence for butchery activities. Thus, determining the spatiotemporal context of increased carnivory in the hominin lineage relies on the accurate identification of fossil BSM.
Multidecade-long debates over the agents responsible for individual BSM indicate systemic flaws in historical approaches to identification. These debates are in part due to the extreme morphological overlap between BSM produced by certain agents of modification. The primary goal of this dissertation project therefore, is to construct probability models of BSM capable of identifying individual marks with an associated probability of assignment. Using a multivariate Bayesian approach to analyze experimentally-generated BSM data, this dissertation uses two different models, one incorporating both two and three-dimensional (3D) metric and attribute data associated with individual BSM and a second model comparing 3D geometric morphometric (GM) shape data associated with BSM.
The 2D/3D attribute model of BSM is used evaluate an assemblage of fossil BSM recovered from the Ledi-Geraru research area, Ethiopia (2.82 Ma) in spatiotemporal association with early Homo. The results of the analysis reveal compelling evidence for early butchery activities, suggesting hominins may have been using both modified and unmodified stone implements to process carcasses.
The second model, based upon 3D GM data, was used to evaluate the earliest purported evidence for stone-mediated butchery at Dikika, Ethiopia (3.39 Ma). The Dikika marks have been argued to be the result of crocodile feeding, trampling, and butchery by three different research groups. The 3D GM model evaluates the likelihood of each of these actors in the production of the controversial Dikika marks.

Description
Researchers and practitioners have widely studied road network traffic data in different areas such as urban planning, traffic prediction and spatial-temporal databases. For instance, researchers use such data to evaluate the impact of road network changes. Unfortunately, collecting large-scale high-quality urban traffic data requires tremendous efforts because participating vehicles must install Global Positioning System(GPS) receivers and administrators must continuously monitor these devices. There have been some urban traffic simulators trying to generate such data with different features. However, they suffer from two critical issues (1) Scalability: most of them only offer single-machine solution which is not adequate to produce large-scale data. Some simulators can generate traffic in parallel but do not well balance the load among machines in a cluster. (2) Granularity: many simulators do not consider microscopic traffic situations including traffic lights, lane changing, car following. This paper proposed GeoSparkSim, a scalable traffic simulator which extends Apache Spark to generate large-scale road network traffic datasets with microscopic traffic simulation. The proposed system seamlessly integrates with a Spark-based spatial data management system, GeoSpark, to deliver a holistic approach that allows data scientists to simulate, analyze and visualize large-scale urban traffic data. To implement microscopic traffic models, GeoSparkSim employs a simulation-aware vehicle partitioning method to partition vehicles among different machines such that each machine has a balanced workload. The experimental analysis shows that GeoSparkSim can simulate the movements of 200 thousand cars over an extensive road network (250 thousand road junctions and 300 thousand road segments).

Description
This project includes composer biographies, program notes, performance guides, composer questionnaires, and recordings of five new and lesser known works for saxophone quartet. Three of the compositions are new pieces commissioned by Woody Chenoweth for the Midwest-based saxophone quartet, The Shredtet. The other two pieces include a newer work for saxophone quartet never recorded in its final version, as well as an unpublished arrangement of a progressive rock masterpiece. The members of The Shredtet include saxophonists Woody Chenoweth, Jonathan Brink, Samuel Lana, and Austin Atkinson. The principal component of this project is a recording of each work, featuring the author and The Shredtet.
The first piece, Sax Quartet No. 2 (2018), was commissioned for The Shredtet and written by Frank Nawrot (b. 1989). The second piece, also commissioned for The Shredtet, was written by Dan Puccio (b. 1980) and titled, Scherzos for Saxophone Quartet (2018). The third original work for The Shredtet, Rhythm and Tone Study No. 3 (2018), was composed by Josh Bennett (b. 1982). The fourth piece, Fragments of a Narrative, was written by Ben Stevenson (b. 1979) in 2014 and revised in 2016, and was selected as runner-up in the Donald Sinta Quartet’s 2016 National Composition Competition. The final piece included in this project is a transcription and arrangement of Tarkus (1971), written by Keith Emerson (1944-2016) and Greg Lake (1947-2016) for the iconic progressive rock supergroup, Emerson, Lake & Palmer. This unique and unpublished arrangement was crafted by Peter Ford (b. 1964) for Ohio-based saxophone quartet Sax 4th Avenue and first featured on the ensemble’s 1998 album, Delusions de Grandeur. These pieces were recorded in the E-Media Studios of the College Conservatory of Music at the University of Cincinnati, as well as A2 Audio Studios in Cincinnati, Ohio, in January and February of 2019.

Description
This is a comparative study of two advanced ordination rituals, Daoist chuanshou (conferral of ordination rank) and Buddhist abhiṣeka (guanding) in the mid-late Tang and Five Dynasties (763-979). I analyzed a number of not-well-studied Daoist ritual protocols in the early medieval period, and revealed that rituals recast gender and fostered monastic relations. On the other hand, relying on both canonical materials and a manuscript preserved in Japan that recorded an abhiṣeka performed during the Tang dynasty in 839 C.E., I demonstrated how the canonical prescriptions of Indian origin, with modified actions and reinterpreted meaning, were transformed to respond to the Chinese religious and social environment. Having examined the language of the texts and the step of the rituals, I interpreted how these rituals were made sense in their own religious context, and compared their frame, structure, modality, symbol, and meaning.
Ordination rite concerns the transmission of religious knowledge and authority, and the establishment of religious identity. It is in the relationship between the individual body and the community that Daoists and Buddhists found the form of apprenticeship that led to the embodiment of the community. The mastery of religious knowledge within the community––scriptures, register, mantras, and precepts, etc., was known only through the actual ritual practice. In other words, the ritual body became the locus for coordination of all levels of bodily, social, and cosmological experience via the dialectic of objectification and embodiment in the ordination rites. As the ritualized bodies, those who were ordained coherently comprised the community, which in turn remolded them with dynamically and diversely shaped identities.

Description
This dissertation details a study of wide-bandgap molecular beam epitaxy (MBE)-grown single-crystal MgxCd1-xTe. The motivation for this study is to open a pathway to reduced $/W solar power generation through the development of a high-efficiency 1.7-eV II-VI top cell current-matched to low-cost 1.1-eV silicon. This paper reports the demonstration of monocrystalline 1.7-eV MgxCd1-xTe/MgyCd1-yTe (y>x) double heterostructures (DHs) with a record carrier lifetime of 560 nanoseconds, along with a 1.7-eV MgxCd1-xTe/MgyCd1-yTe (y>x) single-junction solar cell with a record active-area efficiency of 15.2% and a record open-circuit voltage (VOC) of 1.176 V. A study of indium-doped n-type 1.7-eV MgxCd1-xTe with a carrier activation of up to 5 × 1017 cm-3 is presented with promise to increase device VOC. Finally, this paper reports an epitaxial lift-off (ELO) technology using water-soluble MgTe for the creation of free-standing MBE-grown II-VI single-crystal CdTe and 1.7-eV MgxCd1-xTe solar cells freed from lattice-matched InSb(001) substrates. Photoluminescence (PL) spectroscopy measurements comparing intact and free-standing films reveal the survival of optical quality in CdTe DHs after ELO. This technology opens up several possibilities to drastically increase cell conversion efficiency through improved light management and transferability into monolithic multijunction devices. Lastly, this report will present considerations for future work in each of the study areas mentioned above.

Description
Lidar has demonstrated its utility in meteorological studies, wind resource assessment, and wind farm control. More recently, lidar has gained widespread attention for autonomous vehicles.
The first part of the dissertation begins with an application of a coherent Doppler lidar to wind gust characterization for wind farm control. This application focuses on wind gusts on a scale from 100 m to 1000 m. A detecting and tracking algorithm is proposed to extract gusts from a wind field and track their movement. The algorithm was implemented for a three-hour, two-dimensional wind field retrieved from the measurements of a coherent Doppler lidar. The Gaussian distribution of the gust spanwise deviation from the streamline was demonstrated. Size dependency of gust deviations is discussed. A prediction model estimating the impact of gusts with respect to arrival time and the probability of arrival locations is introduced. The prediction model was applied to a virtual wind turbine array, and estimates are given for which wind turbines would be impacted.
The second part of this dissertation describes a Time-of-Flight lidar simulation. The lidar simulation includes a laser source module, a propagation module, a receiver module, and a timing module. A two-dimensional pulse model is introduced in the laser source module. The sampling rate for the pulse model is explored. The propagation module takes accounts of beam divergence, target characteristics, atmosphere, and optics. The receiver module contains models of noise and analog filters in a lidar receiver. The effect of analog filters on the signal behavior was investigated. The timing module includes a Time-to-Digital Converter (TDC) module and an Analog-to-Digital converter (ADC) module. In the TDC module, several walk-error compensation methods for leading-edge detection and multiple timing algorithms were modeled and tested on simulated signals. In the ADC module, a benchmark (BM) timing algorithm is proposed. A Neyman-Pearson (NP) detector was implemented in the time domain and frequency domain (fast Fourier transform (FFT) approach). The FFT approach with frequency-domain zero-paddings improves the timing resolution. The BM algorithm was tested on simulated signals, and the NP detector was evaluated on both simulated signals and measurements from a prototype lidar (Bhaskaran, 2018).

Description
The shift in focus of manufacturing systems to high-mix and low-volume production poses a challenge to both efficient scheduling of manufacturing operations and effective assessment of production capacity. This thesis considers the problem of scheduling a set of jobs that require machine and worker resources to complete their manufacturing operations. Although planners in manufacturing contexts typically focus solely on machines, schedules that only consider machining requirements may be problematic during implementation because machines need skilled workers and cannot run unsupervised. The model used in this research will be beneficial to these environments as planners would be able to determine more realistic assignments and operation sequences to minimize the total time required to complete all jobs. This thesis presents a mathematical formulation for concurrent scheduling of machines and workers that can optimally schedule a set of jobs while accounting for changeover times between operations. The mathematical formulation is based on disjunctive constraints that capture the conflict between operations when trying to schedule them to be performed by the same machine or worker. An additional formulation extends the previous one to consider how cross-training may impact the production capacity and, for a given budget, provide training recommendations for specific workers and operations to reduce the makespan. If training a worker is advantageous to increase production capacity, the model recommends the best time window to complete it such that overlaps with work assignments are avoided. It is assumed that workers can perform tasks involving the recently acquired skills as soon as training is complete. As an alternative to the mixed-integer programming formulations, this thesis provides a math-heuristic approach that fixes the order of some operations based on Largest Processing Time (LPT) and Shortest Processing Time (SPT) procedures, while allowing the exact formulation to find the optimal schedule for the remaining operations. Computational experiments include the use of the solution for the no-training problem as a starting feasible solution to the training problem. Although the models provided are general, the manufacturing of Printed Circuit Boards are used as a case study.

Description
This mixed-methods study explored perceptions of new adjuncts on various trainings with regards to satisfying their professional and aspirational needs. Three trainings were offered in fall 2018 quarter as optional professional development: workshop, and two roundtable sessions. These trainings assisted adjuncts with their teaching skills, educational technology and pedagogy. Guidance was provided from experienced adjuncts and staff.
Surveys and interviews with adjuncts, along with a focus group with staff were the sources of data for this study. A repeated measures Analysis of Covariance (ANCOVA) model was utilized. Analysis of data showed that there was a positive and statistical significance of change in perceptions of adjuncts who participated in all trainings towards fulfilling their needs, as compared to those who did not participate in any trainings. Adjuncts perceived an improvement in their professional growth based on Herzberg’s motivation-hygiene theory and the trainings also fulfilled their higher-level growth needs based on Maslow’s hierarchical needs theory. A large practical significance was also found which measures the practical impact of such trainings at local communities of practice.
