description: This thesis, with the multiple streams framework (MSF) and the new institutionalism (NI) as theoretical lenses, seeks to understand the factors that shape policy making and policy change in post-independence Ghana. More specifically, it seeks to provide a better understanding of the factors that have led Ghana after independence to achieve remarkable, path-departing, substantive change in its health and local governance policies but marginal or incremental changes in its education policy. I argue that policy entrepreneurs and government political will in the form of demonstrated credible intent and commitment of the government culminating in partisan decisions greatly shaped the different policy outcomes and differing magnitude of change in Ghana’s local governance, health, and education policies at specific moments in time. Institutions affect the efforts of policy entrepreneurs and the government to carry out a proposed policy change. Understanding public policy making and policy change is of vital importance because public policies involve who gets what in politics. Thus, there is the need to examine the determinants of public policies and the drivers of policy change. Yet, the analysis of policy making and policy change in Africa, particularly Ghana, has been a neglected area of study. Hence, policy making and policy change in Africa has not been sufficiently explored. Besides, comparative understanding of policy making and policy change in Ghana is under researched. The study, therefore, helps to fill this gap by comparatively analysing how political will and commitment of the government and policy entrepreneurs interact differently to drive policy making and policy change at specific moments in time in Ghana. Relying on the MSF, while paying attention to the impact of differing institutions on the streams, helps to provide a deeper understanding of the policy making process and policy change. Methodologically, the comparative case study method helps in identifying variations, patterns and commonalities in health, education, and local governance policy making and policy change in Ghana. Theoretically, the study aims first, to extend the applicability of the MSF in examining policy making to Ghana and second, to provide a deeper understanding by combining the MSF and the NI.

description: As artistic athletes, dancers participate in long hours of training, increasing their risk of injury. Workload, which describes how much and how hard dancers work, can improve our understanding of dancers’ training and lead to the development of effective injury prevention strategies. Therefore, the main objective of this thesis was to investigate dancers’ workloads across all dance genres and dance levels of participation, examine how wellness factors influence dancers’ workloads, and explore dancers’, dance teachers’ and dance parents’ attitudes and current use practices of wearable technology in the dance studio environment. In Chapter Two, a systematic search of the literature identified that the most common tool used to quantify dancers’ workload was ‘hours’, although it does not account for the intensity of dance training. The observed trend in dance workload research is moving from capturing only exposure or intensity of training, to capturing workload where both the volume and intensity of dance training is considered. In Chapter Three, longitudinal monitoring of female undergraduate university dancers’ workloads and wellness found that the dancers’ workloads were not significantly associated with any of the seven wellness factors examined. In Chapter Four, dancers’ external workloads were quantified using wearable technology and video movement analysis. Dancers’ external workloads were higher than 70,000AU in a session, and were larger in classes than rehearsals. In a typical dance session, transitions were the most commonly performed dance movement, followed by floor rolls, and jumps. In Chapter Five, dancers, dance teachers, and dance parents reported modest attitudes towards wearable technology and high self-efficacy of using wearable technology. Prevalence of using wearables in the studio was approximately 50%, with smartwatches and wristband activity trackers being the most common devices used. Identified barriers to using wearables in dance included dance studio rules, not having a device, and lack of interest in wearables. In conclusion, a wide range of tools and devices can be used to monitor dancers’ workloads, allowing for prospective workload monitoring, and paving the way for the workload-injury association to be examined in dance.

Housing and location of young adults, then and now : consequences of urban restructuring in Montreal and Vancouver
Creators: name: Moos, Markus
Publisher: name: University of British Columbia
Year: 2012

description: Young adults, 25 to 34 years of age, decide on housing, residential location and commuting patterns in an altered context from when the same age cohort entered housing markets in the early 1980s. Neo-liberalization reduced the availability of low-cost, rental housing, and post-Fordist restructuring increased labour market inequality. Societal changes contributed to decreases in household size and delay in child bearing. This thesis asks how the contextual changes factor into young adults’ housing decisions in the Montreal and Vancouver metropolitan areas where restructuring occurred differently, and discusses implications for equity and sustainability. The young adult residential ecology is increasingly concentrated into higher density and amenity-rich neighbourhoods, particularly near transit in Vancouver. The trends are explained by shifts toward the service sector, declining real incomes and growing inter-generational wage inequalities that reduce young adults’ spending power in housing markets, especially in Vancouver with its speculative land market and wealthy immigrants. Holding other characteristics constant, young adults in Vancouver are less likely to reside in single-family dwellings than detached, row or apartment units. In Montreal the trend is toward single-family living. Commuting distances and modes are similar between Vancouver and Montreal but multiple-person households and those with children have longer and more automobile-oriented commutes in Vancouver. The changes reflect higher increases in housing costs and densities in central areas in Vancouver. Montreal has more sustained government support for housing, a larger rental sector and therefore less rampant increases in housing costs. The restructuring of Vancouver’s housing market makes it more difficult than in Montreal to keep accessible the more ‘sustainable’ locations to households of all sizes. Household structure and life-cycle stage, not social status alone, determine location and the commute. A greater sustainability challenge in Montreal will be to stem the shifts toward ownership of single-family dwellings. Generally, young adults’ housing outcomes are more evidently shaped by their position in the labour market, which is increasingly determined by educational attainment. The thesis works conceptually within structuration theory, noting how contexts shape demand but are themselves re-shaped by changing demand. Both contextual and neo-classical arguments have relevance to the overall argument.

description: Our work explores the potential of using anthropomorphism to improve Autonomous Vehicle (AV)-pedestrian interactions. Inspired by human-human and human-robot communication, we propose designs for AV interfaces that leverage non-verbal anthropomorphic characteristics: facial expression, hand gesture, and body movement. For each category, we identified a series of design variants. We used a physical prototype to present hand gestures (Video 1) and sketches to present facial expressions and body movements. We then implemented some of them in VR environment and conducted an evaluation (Video 2).

description: We study the distance-redshift relation in a universe filled with 'walls' of pressure-less dust separated by under dense regions. We show that as long as the density contrast of the walls is small, or the diameter of the under dense regions is much smaller than the Hubble scale, the distance-redshift relation remains close to what is obtained in a Friedmann universe. However, when arbitrary density contrasts are allowed, every prescribed distance-redshift relation can be reproduced with such models.

Convergence Basin Analysis in Perturbed Trajectory Targeting Problems
Creators: name: York, Collin E.
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Flight dynamics

description: Increasingly, space flight missions are planned to traverse regions of space with complex dynamical environments influenced by multiple gravitational bodies. The nature of these systems produces motion and regions of sensitivity that are, at times, unintuitive, and the accumulation of trajectory dispersions from a variety of sources guarantees that spacecraft will deviate from their pre-planned trajectories in this complex environment, necessitating the use of a targeting process to generate a new feasible reference path. To ensure mission success and a robust path planning process, trajectory designers require insight into the interaction between the targeting process, the baseline trajectory, and the dynamical environment. In this investigation, the convergence behavior of these targeting processes is examined. This work summarizes a framework for characterizing and predicting the convergence behavior of perturbed targeting problems, consisting of a set of constraints, design variables, perturbation variables, and a reference solution within a dynamical system. First, this work identifies the typical features of a convergence basin and identifies a measure of worst-case performance. In the absence of an analytical method, efficient numerical discretization procedures are proposed based on the evaluation of partial derivatives at the reference solution to the perturbed targeting problem. A method is also proposed for approximating the tradespace of position and velocity perturbations that achieve reliable convergence toward the baseline solution. Additionally, evaluated scalar quantities are introduced to serve as predictors of the simulation-measured worst-case convergence behavior based on the local rate of growth in the constraints as well as the local relative change in the targeting-employed partial derivatives with respect to perturbations.
 A variety of applications in different dynamical regions and force models are introduced to evaluate the improved discretization techniques and their correlation to the predictive metrics of convergence behavior. Segments of periodic orbits and transfer trajectories from past and planned missions are employed to evaluate the relative convergence performance across sets of candidate solutions. In the circular restricted three-body problem (CRTBP), perturbed targeting problems are formulated along a distant retrograde orbit and a near-rectilinear halo orbit (NRHO) in the Earth-Moon system. To investigate the persistence of results from the CRTBP in an ephemeris force model, a targeting problem applied to an NRHO is analyzed in both force models. Next, an L1 -to-L2 transit trajectory in the Sun-Earth system is studied to explore the effect of moving a maneuver downstream along a trajectory and altering the orientations of the gravitational bodies. Finally, a trans-lunar return trajectory is explored, and the convergence behavior is analyzed as the final maneuver time is varied.

description: CeNi0.8Bi2 is very recent entrant in superconductivity kitchen [1], and the same seeks reproduction from other groups. We report synthesis, structural details and superconductivity in CeNi0.8Bi2 compound. The CeNi0.8Bi2 compound is synthesized by solid state reaction route via vacuum encapsulation of high purity mixed Ce, Ni, Bi and subsequent heating of the same at 500 0C for 10 hours followed by annealing at 750 0C for 20 hours. As synthesized compounds are dark grey in color and do crystallize in tetragonal structure with space group P4/nmm. The lattice parameters are a = 3.61 Å and c = 10.20 Å. AC susceptibility measurements showed that synthesized CeNi0.8Bi2 compound is weakly superconducting below 4.2K. We believe our article will regenerate fresh activity to look for bulk superconductivity in CeNi0.8Bi2.

description: The CP violation of the neutral $B$ meson is the important phenomenon to search for the new physics. The like-sign dimuon charge asymmetry observed by the D$Ø$ Collaboration indicates the CP-violating new physics in the $B_s-\bar B_s$ mixing. On the other hand, LHCb observed the CP-violating asymmetry in $B_s^0\to J/ψϕ$ and $B_s^0\to J/ψf_0(980)$, which is consistent with the SM prediction. However, there is still room for new physics of the CP violation. The CKMfitter has presented the allowed region of the new physics parameters taking account of the LHCb data. Based on these results, we discuss the effect of the squark flavor mixing on the CP violation in the $B_d$ and $B_s$ mesons. We predict asymmetries in the non-leptonic decays $B_d^0\to ϕK_S$, $B_d^0\to η'K^0$, $B_s^0\to ϕϕ$ and $B_s^0\to ϕη'$.

We consider the thermodynamics of black branes and find different low-temperature behavior of the specific heat. Deformation away from criticality leads to non-trivial temperature dependence of correlation functions and we study how the characteristic length scale in the two point function of scalar operators varies as a function of temperature and deformation parameters.

Theor. 45 (2012), 405301, 13 pages] have given a number of distinct sets of three-qubit observables, each furnishing a proof of the Kochen-Specker theorem. Here it is demonstrated that two of these sets/configurations, namely the $18_{2} - 12_{3}$ and $2_{4}14_{2} - 4_{3}6_{4}$ ones, can uniquely be extended into geometric hyperplanes of the split Cayley hexagon of order two, namely into those of types ${\cal V}_{22}(37; 0, 12, 15, 10)$ and ${\cal V}_{4}(49; 0, 0, 21, 28)$ in the classification of Frohardt and Johnson [Comm. Algebra 22 (1994), 773-797]. Moreover, employing an automorphism of order seven of the hexagon, six more replicas of either of the two configurations are obtained.

description: The performance potential for simulating quantum electron transport on graphical processing units (GPUs) is studied. Using graphene ribbons of realistic sizes as an example it is shown that GPUs provide significant speed-ups in comparison to central processing units as the transverse dimension of the ribbon grows. The recursive Green's function algorithm is employed and implementation details on GPUs are discussed. Calculated conductances were found to accumulate significant numerical error due to single-precision floating-point arithmetic at energies close to the charge neutrality point of the graphene.

Belief, Action, And Performance: Evidence From Mutual Funds And Corporate Events
Creators: name: Wang, Shimeng
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Finance

description: This dissertation studies the impact of mutual fund managers' beliefs on fund performance in the first chapter and focuses on the impact of firm behavior on stock performance in the second chapter.
 In the first chapter, I utilize the Revealed Preference Theory to recover fund manager belief formation directly from their actual trading activities. By relating stock holdings in a fund's portfolio to past factor returns, I document three facts about managers' belief formation: 1. In contrast to belief extrapolation, a substantial fraction of mutual fund managers act as contrarian investors who expect lower factor returns after a good factor performance; 2. Whether a fund trades in an extrapolative or contrarian way is due to its managers' expectation biases rather than fund style investment strategy, fund catering strategy or fund risk preference; and 3. Contrarian managers generate superior performance, are more experienced investors, charge higher expense ratios, and manage smaller US equity funds. The top (contrarian) managers significantly outperform the bottom (extrapolative) managers by a return of 3.4% per annum after adjusting by FFC4 factor models.
 The second chapter is co-authored paper with Yan Liu and Feng Zhang. In this chapter, we systematically replicate the bulk of long-run event studies conducted in the last three decades from 1990 to 2020 using extended samples and four long-run performance measures. The final sample contains 62 papers of long-run event studies and 148 corporate events. Our findings suggest that long-run return anomalies documented in the last three decades are not robust, and firms do not earn long-run abnormal returns following various types of corporate events. Only 2% of the 148 corporate events we replicate earn post-event abnormal returns that are statistically significant at the 5% level based on all the four performance measures, and the fraction further shrinks to 0% at the 1% significance level. Viewed together, our findings suggest that these long-run abnormal returns after corporate events are likely the result of data mining or "p-hacking".

description: Cooperation is crucial for the remarkable evolutionary success of the human species. Not surprisingly, some individuals are willing to bare additional costs in order to punish defectors. Current models assume that, once set, the fine and cost of punishment do not change over time. Here we show that relaxing this assumption by allowing players to adapt their sanctioning efforts in dependence on the success of cooperation can explain both, the spontaneous emergence of punishment, as well as its ability to deter defectors and those unwilling to punish them with globally negligible investments. By means of phase diagrams and the analysis of emerging spatial patterns, we demonstrate that adaptive punishment promotes public cooperation either through the invigoration of spatial reciprocity, the prevention of the emergence of cyclic dominance, or through the provision of competitive advantages to those that sanction antisocial behavior. Presented results indicate that the process of self-organization significantly elevates the effectiveness of punishment, and they reveal new mechanisms by means of which this fascinating and widespread social behavior could have evolved.

description: We study a generic two-dimensional hopping model on a honeycomb lattice with strong spin-orbit coupling, without the requirement that the half-filled lattice be a Topological Insulator. For quarter-(or three-quarter) filling, we show that a state with a quantized Hall conductance generically arises in the presence of a Zeeman field of sufficient strength. We discuss the influence of Hubbard interactions and argue that spontaneous ferromagnetism (which breaks time-reversal) will occur, leading to a quantized anomalous Hall effect.

description: Blood oxygen level dependent (BOLD) signal variability characterizes the inherently time-varying features of brain signal and has provided complementary perspectives into aging research. As a strong age predictor, age-related brain patterns that are associated with BOLD SD barely overlap with those from the mean BOLD signal. The three studies in this thesis elucidate what BOLD signal variability (quantified by standard deviation (SD) of BOLD time series) can tell us about brain structure and function relationships across the lifespan from childhood to adulthood. Study 1 explored the association between BOLD SD, age, and white matter development during early childhood. Across- and within-participant analyses demonstrated that white matter maturation was closely linked to alterations in brain function as measured by BOLD SD. Study 2 examined the relationship between age and brain function for healthy men and women using a context memory task. Although men and women performed equally well behaviorally, neurotypical aging showed different trajectories between the sexes; BOLD SD in women showed age vs performance trade-offs in widespread cortical and subcortical regions, whereas in men, BOLD SD patterns associated with age and performance were orthogonal and task-specific. To better understand how BOLD SD relates to other, more commonly used measures of brain function, Study 3 related BOLD SD to other metrics, some of them reflecting brain dynamics, e.g., BOLD signal complexity (quantified by multi-scale entropy), functional connectivity and dynamic functional connectivity. This work suggests that the relationship between BOLD SD and complexity is time scale dependent, with a positive correlation at fine scales but a negative one at coarse scale. The link between BOLD SD and dynamic functional connectivity preserved only part of the associations between BOLD SD and static functional connectivity, which revealed how brain signal and brain functional connectivity co-evolved over time. Taken together, these studies suggest that BOLD SD can be used to elucidate maturational-, aging- and sex-associated differences in brain structure and function. Relating BOLD SD to other measures of brain function may improve our understanding of how the dynamic features of brain states evolve across the lifespan.

THE SEMANTICS OF NEGATIVE AFFIXES AND THEIR COMPARATIVE ANALYSIS
Creators: name: Ochilova, Nasiba
Publisher: name: Zenodo

description: The aim of the article is to single out, describe, compare and find the possible ways of classification of English negative affixes. We will familiarize ourselves with English negative affixes, learn how they differ semantically from each other, which affixes are used with stems of different parts of speech and what parts of speech they form (there we can also see if these affixes are able to transform words of one part of speech into another), what their functions and peculiarities of usage are, and which affixes are more productive and widely used nowadays. It is very important to know as more affixes, as possible, because many English words are formed by combining prefixes and suffixes to base words.
The Women of Britannia: Female Identities on the Romano-British Frontier from 100 BC to 300 AD

description: Increased archaeological interest in the frontiers of the Roman world and interest in past constructions of gender and sexuality have created an opportunity for archaeologists to explore these elements of identity in more depth in the more dynamic regions of the empire. Northern Britannia was a site of complex processes of culture contact and colonial practices which affected the local population and those who came to this frontier area of the Roman Empire. This study includes context and practices from the late Iron Age through Roman conquest, until 300 AD. Within the study area, changes in agriculture, production, trade, burial practices, and material culture began to take place in the late Iron Age due to increased contact with the continent and southern Britain, and these changes continued throughout conquest and into the Roman period. In order to discuss gender and identity within Northern Britannia, classical sources, contemporary records and personal correspondence, funerary monumentation, burial practices, grave goods, personal ornamentation and clothing, as well as traditionally gendered items such as weaving implements were analyzed within the context of Roman ideals for the status and behaviour of women. Classical sources provide information about the Roman ideal woman, including being a loyal wife, mother and someone who provided for her family through traditional activities such as weaving and childcare. Contemporary records and personal correspondence show the nature of the activities and relationships of women at the site of Vindolanda, both higher status and women associated with soldiers in the area. Funerary monumentation illustrated local identities through local names, tribal associations, representations of hairstyles and clothing, and that status and military association was an integral part of the everyday creation and expression of women’s identities. Burial practices indicate strong associations between women and childcare that spanned the Iron Age and Roman periods, and that status played a large role in how women were buried, and what with. Items of personal ornamentation and clothing mirrored the correlation between women and children/childcare, expression of local identities, the importance of status that at times surpassed gender in identity expression.

description: Arsenic is a natural but toxic element considered by the World Health Organization to be a chemical of major public health concern globally. Biomarkers are a tool used to understand exposure to chemicals (e.g., arsenic) and their impacts on the health of a population. In Yellowknife, past mining activities have resulted in a toxic legacy of arsenic impacting the surrounding environment. However, current human exposure levels in the area are largely unknown. In this thesis, I demonstrate how different biomarkers can be used to evaluate arsenic exposure and associated health effects in the human population of Yellowknife and the First Nation communities of Dettah and Ndilo. First, I established baseline levels of arsenic exposure within the Yellowknife population by measuring urinary arsenic concentrations via speciation analysis. I also used general guidance values for urinary arsenic to assess arsenic exposure and health risks in Yellowknife compared to the general Canadian population. Children in Yellowknife had significantly higher urinary inorganic arsenic concentrations than Yellowknife adults and children in the general Canadian population. Second, I expanded on the baseline arsenic exposure levels by analyzing toenail arsenic via speciation analysis, demonstrating that toenail arsenic reflects a different exposure period than urine and may potentially indicate external environmental sources. Then, I evaluated two proteins, KIM-1 and CC16, as candidate biomarkers of effect for detecting lung and kidney impairment in children from exposure to arsenic and other contaminants (e.g., lead and manganese). Finally, I reviewed past archival human arsenic data to understand historical arsenic exposure and how past exposures compare to current levels. I have demonstrated that different biomarkers can contribute to understanding arsenic exposure and its subsequent impacts on the Yellowknife population and other populations with similar environmental health concerns. Additionally, the results of my research contribute to public health policy and decision-making.
Effects of static charging and exfoliation of layered crystals

description: Using first-principle plane wave method we investigate the effects of static charging on structural, elastic, electronic and magnetic properties of suspended, single layer graphene, graphane, fluorographene, BN and MoS2 in honeycomb structures. The limitations of periodic boundary conditions in the treatment of charged layers are clarified. Upon positive charging the band gaps between the conduction and valence bands increase, but the single layer materials become metallic owing to the Fermi level dipping below the maximum of valence band. Moreover, their bond lengths increase and their in-plane stiffness decreases. As a result, phonons are softened and frequencies of Raman active modes are lowered. High level of charging leads to instability. We showed that wide band gap BN and MoS2 slabs are metallized as a result of electron removal and their outermost layers are exfoliated once the charging exceeds a threshold value.

description: The DEK proto-oncogene is a nuclear protein important in regulating many cellular processes including DNA double-strand break repair and chromatin biology, through protein-protein and protein-nucleic acid interactions. Mutations or altered expression of DEK result in the development of various human diseases including acute myeloid leukemia and many other types of cancer. However, despite its importance in biology, there is a lack in knowledge on the mechanistic and structural basis for how DEK interactions regulate the numerous cellular processes it is involved in. Here, I developed purification protocols for full-length and subdomains of DEK, and developed biochemical assays to investigate DEK-DNA interactions and role of DEK in regulating homologous recombination repair. The DNA binding results showed that DEK can bind a wide variety of DNA substrates with a range of affinities between ⁓130-1300 nM. Phosphorylation of full-length DEK blocked DNA binding, consistent with and extending published work. The preliminary homologous recombination repair results showed that DEK directly binds to the RAD51 recombinase in vitro and may promote RAD51-mediated double-stranded DNA displacement during strand invasion. The results and protocols developed from this thesis provide a platform for future efforts to further characterize DEK’s role in HRR, to test the effects of disease-associated mutations, and to determine structures of DEK complexes with DNA, RAD51, and other interacting proteins including the nucleosome. This future work will address the gap in knowledge regarding the mechanistic basis for DEK’s role in homologous recombination repair and may provide new insights into its functions in human diseases.
