description: Wearable physical activity (PA) monitors have been adopted by millions of people across the United States, but we do not fully understand who wears them and why. The devices have been promoted as a tool that motivates users by collecting data on their daily activities and delivering tailored feedback based on predetermined goals. The purpose of this dissertation was twofold: 1) To describe users of activity monitors detailing how and why they used this technology, and 2) To explore the motivational profile of activity monitor users and assess how it is related to PA. This dissertation consists of a series of two separate but related studies.
      	The first study recruited over 2000 activity monitor users from across the United States to complete a web-based survey describing why they used this technology and how they interacted with their device. This study showed significant differences in sociodemographic and use characteristics between current and former users and between women and men. Activity monitors were perceived by users as influential on their PA behavior and differences in use patterns between subgroups warranted further exploration of associations between user characteristics, motivation to exercise, and PA.
      	The second study investigated the motivation and PA of activity monitor users. While activity monitors have been widely promoted as a means to motivate users to be more active, the motivational profile of users has never been assessed. While all motivational regulations were significantly correlated with PA, the strongest associations were with the more self-determined motives (integrated, identified and intrinsic respectively). Five motivational profiles emerged from the cluster analysis: ‘High Amotivation’ (n=30), ‘Autonomous with High Introjected’ (n=101), ‘Low Overall Motivation’ (n=61), ‘High Controlled Motivation (n=47), and ‘Autonomous with Low Introjected’ (n=81). Profiles characterized by more autonomous regulations had higher levels of PA.
      	These studies offer new insights on who activity monitor users are, why they decide to use this technology, and how they interact with their devices. While the second study identified an association between motivational profiles and PA, further longitudinal research is needed to assess whether use of an activity monitor impacts the direction and/or magnitude of this relationship.
title: Transnational families and digital technologies: Parenting at a distance among Chinese families
Creators: name: Chen, Hong
Publisher: name: Goldsmiths, University of London
Year: 2020

description: This thesis aims to address how Chinese transnational family members involved in the ‘caregiving triangle’ – migrant parents, left-behind children and guardians (Suarez-Orozco et al., 2002) – navigate new media environments to negotiate their family roles and maintain kinship ties. Acknowledging the structural ‘asymmetrical reciprocity’ (Baldassar & Merla, 2014) of transnational families – which derives from the intersection of internal factors (including family obligation, expectations and norms) and external transnational socioeconomic contexts – this study examines the power dynamics and care circulation through mediated communication among family members across borders. To this end, this study employs a three-year multi-sited ethnography, including participant observation, in-depth interviews and online ethnography of Chinese labour migrants in Britain (mainly clandestine and low-skilled workers) and their family members, conducted between 2015 and 2018. The findings highlight the varied forms of agency and challenges experienced by migrant and non-migrant family members embedded in different social-technical contexts. Notable among these are: the transnational family structure; migration status and generation; Chinese patriarchal ideology; and the socio-economic discrepancies between Britain and (rural) China, which contribute to the shaping of mediated transnational communication. The adoption of communication technology in transnational family life has minimized the geographical and temporal constraints that divide these dispersed family members and enhanced the ‘reciprocity’ between them (including childrearing collaboration between migrant parents and guardians and strengthened intergenerational solidarity between migrant parents and children). However, it has also exacerbated the ‘asymmetry’ of transnational families, such as increased gendered parenting burdens and parental surveillance over left-behind children. This study argues that this mediated ‘asymmetrical reciprocity’ is subject to constant negotiation, as a consequence of unconfined translocal family settings along with the affordances of communication technologies.

description: We show that the classification performance of graph convolutional networks (GCNs) is related to the alignment between features, graph, and ground truth, which we quantify using a subspace alignment measure (SAM) corresponding to the Frobenius norm of the matrix of pairwise chordal distances between three subspaces associated with features, graph, and ground truth. The proposed measure is based on the principal angles between subspaces and has both spectral and geometrical interpretations. We showcase the relationship between the SAM and the classification performance through the study of limiting cases of GCNs and systematic randomizations of both features and graph structure applied to a constructive example and several examples of citation networks of different origins. The analysis also reveals the relative importance of the graph and features for classification purposes.

description: This dissertation analyzes the legacy of Protestant allegory in eighteenth-century fictions. In doing so, the dissertation shows that personifications and allegorically inflected characters became increasingly opaque and vulnerable to charges of impersonation as the novel developed in the early and middle eighteenth century. I attribute the distortion of allegorical representation to the conflicting yet intermeshed interpretive frameworks that allegory and the novel demand of their readers. For evidence, I primarily analyze John Bunyan’s The Pilgrim Progress, Jonathan Swift’s A Tale of a Tub, Samuel Richardson’s Pamela, and Henry Fielding’s Jonathan Wild.

description: We examine the different possible symmetries of the superconducting gap obtained by solving the Eliashberg equations. We consider an electron-phonon interaction in a strong coupling scenario. The Coulomb pseudopotential plays the crucial role of providing the repulsion needed to favour the d-wave symmetry. But the key parameter that allows very anisotropic solutions even with very strong coupling is the small angular range of the interaction due to predominantly electron-phonon forward scattering that is found in the high-Tc superconductors. We find both s and d-wave solutions whose stability depends mainly on the angular range of the interaction.

Friction Unwound: A Comprehensive Exploration of Ehl with Point Contact in Helical Gears

description: Gears, as fundamental components of mechanical transmission systems, play an integral role in various machinery applications. Among the plethora of gear types, helical gears stand out for their remarkable attributes such as high bearing capacity, minimal axial load, and smooth transmission. These qualities make them ideal for high-speed and heavy-load operations, positioning them as vital drive components in aero-engines, crane structures, and marine power transmission systems. As gear drives advance towards higher speeds, heavier loads, and greater precision, there is a growing emphasis on enhancing lubrication performance and mitigating friction and wear on tooth surfaces. In theory, the elastohydrodynamic lubrication (EHL) of helical gear drives occurs as an on-line contact phenomenon, disregarding processing errors, installation inaccuracies, and gear modifications. However, real-world industrial production often necessitates the modification of helical gears to evenly distribute lateral loads across the tooth surface, diminish offset loads, reduce rodent impacts, and ultimately mitigate vibration and noise. When dealing with modified helical gears, the conventional linear contact EHL model becomes inapplicable. Consequently, there is an essential need to delve into the realm of Point Contact Elastohydrodynamic Lubrication (PC-EHL) in the context of helical gears

description: Urban intersections, merging roadways, roundabouts, and speed reduction zones along with the driver responses to various disturbances are the primary sources of bottlenecks in corridors that contribute to traffic congestion. The implementation of connected and automated technologies can enable a novel computational framework for real-time control aimed at optimizing energy consumption and travel time. In this paper, we propose a decentralized energy-efficient optimal control framework for two adjacent intersections. We derive a closed-form analytical solution that includes interior boundary conditions and evaluate the effectiveness of the solution through simulation. Fuel consumption and travel time are significantly reduced compared to the baseline scenario designed with conventional fixed time signalized intersections.
Lake creation and development at an Alberta foothills coal mine
Creators: name: Brinker, Curtis
Publisher: name: The University of British Columbia
Year: 2009

description: The creation of lakes for fisheries habitat and recreational opportunities can be a cost-effective method of reclaiming coal mine pits. In the Alberta foothills environment, the sustainable viability of such lakes is a key consideration in determining how appropriate this technique is. In the past six years, two sets of lakes have been created in the final cuts of dragline pits at the Coal Valley Mine, in the Alberta foothills. These two lakes have been designed and constructed to meet recreational and fisheries habitat land uses. Data collected from these lakes since their creation, indicate that water quality characteristics are suitable for development of both end land uses. Results of recent biotic surveys indicate that benthic and aquatic macrophyte communities are establishing, and that a limited fish stocking program could now be supported. This paper discusses the physical and biological characteristics of these two lakes in terms of their long-term viability and fulfillment of land use objectives.

description: Rabies remains a pressing global public health issue, demanding effective modeling and control strategies. This study focused on developing a mathematical model using ordinary differential equations (ODEs) to estimate parameters and assess uncertainties related to the transmission dynamics of rabies in humans and dogs. To determine model parameters and address uncertainties, next-generation matrices were utilized to calculate the basic reproduction number ${\cal R}_{0}$. Furthermore, the Partial Rank Correlation Coefficient was used to identify parameters that significantly influence model outputs. The analysis of equilibrium states revealed that the rabies-free equilibrium is globally asymptotically stable when $R_0<1$, whereas the endemic equilibrium is globally asymptotically stable when ${\cal R}_{0}\geq 1$. To reduce the severity of rabies and align with the Global Rabies Control (GRC) initiative by 2030, the study recommends implementing control strategies targeting indoor domestic dogs.

description: We develop a systematic method to solve the Cardy condition for the coset conformal field theory G/H. The problem is equivalent to finding a non-negative integer valued matrix representation (NIM-rep) of the fusion algebra. Based on the relation of the G/H theory with the tensor product theory G x H, we give a map from NIM-reps of G x H to those of G/H. Our map provides a large class of NIM-reps in coset theories. In particular, we give some examples of NIM-reps not factorizable into the G and the H sectors. The action of the simple currents on NIM-reps plays an essential role in our construction. As an illustration of our procedure, we consider the diagonal coset SU(2)_5 x SU(2)_3 /SU(2)_8 to obtain a new NIM-rep based on the conformal embedding su(2)_3 \oplus su(2)_8 \subset sp(6)_1.

Transitions in Biological Organisation
Creators: name: Calcott, Brett
Publisher: name: The Australian National University
Year: 2006

description: The biological world is hierarchically organised – larger wholes are composed of smaller parts. One take on the different levels might look like this: genes, cells, organs, multicellular organisms, social groups of animals, species, and ecological communities. What processes formed this hierarchy? For the hierarchical structure has a history – many parts and wholes that we now take for granted simply did not exist before. In some cases parts aggregated to form a larger whole: once free-living ants formed the first eusocial colonies. In other cases, the parts were formed within an already aggregated whole: kidneys, hearts, and the like came after multicellular creatures were formed. What can we say in general about these repeated transitions in biological organisation? Can we explain the production of each new level by appealing to the same, or similar, processes? The thesis addresses some of these questions, and how we might go about answering them.
IMPACT OF HOLISTIC MARKETING PHILOSOPHY ON CUSTOMER LOYALTY IN RETAIL BANKING WITH SPECIAL REFERENCE TO PUBLIC SECTOR BANKS IN KERALA

Publisher: name: Zenodo
Year: 2024

description: In the dynamic landscape of the retail banking sector, the pursuit of customer loyalty stands as an evergreen quest. Banking institutions worldwide are confronted with the challenge of not only attracting but also retaining customers in an environment characterized by increasing competition, evolving customer preferences, and digital transformation. The province of Kerala,known for its rich cultural heritage and distinct socio-economic dynamics, presents a particularly intriguing context for this exploration. Public sector banks in Kerala, as staunch pillars of financial inclusion and economic development, have played a pivotal role in serving the diverse needs of the state's populace. However, their journey towards nurturing customer loyalty in this age of heightened expectations requires a profound shift in perspective. This shift finds its resonance in the holistic marketingphilosophy, an approach that recognizes the interconnectedness of all marketing elements and  their collective influence on customer experiences.

In this framework, a linear algebraic view of trigonometry is presented, which allows the associated three-dimensional vector space of such a three-dimensional affine space to be equipped with a non-degenerate symmetric bilinear form; this will also generalise the results presented to arbitrary geometries parameterised by such a non-degenerate symmetric bilinear form.

A multilevel Monte Carlo method for asymptotic-preserving particle schemes in the diffusive limit

description: Kinetic equations model distributions of particles in position-velocity phase space. Often, one is interested in studying the long-time behavior of particles in high-collisional regimes in which an approximate (advection)-diffusion model holds. In this paper we consider the diffusive scaling. Classical particle-based techniques suffer from a strict time-step restriction in this limit, to maintain stability. Asymptotic-preserving schemes avoid this problem, but introduce an additional time discretization error, possibly resulting in an unacceptably large bias for larger time steps. Here, we present and analyze a multilevel Monte Carlo scheme that reduces this bias by combining estimates using a hierarchy of different time step sizes. We demonstrate how to correlate trajectories from this scheme, using different time steps. We also present a strategy for selecting the levels in the multilevel scheme. Our approach significantly reduces the computation required to perform accurate simulations of the considered kinetic equations, compared to classical Monte Carlo approaches.

description: Using simple radiofrequency (RF) instrumentation, we detect spontaneous RF emission from Drosophila immersed in a magnetic field within a waveguide or a shielded RF resonator. Remarkably, the RF emissions are abolished by chloroform anesthesia. Conversely, activation of the nervous system by temperature-sensitive cation channels causes bursts of radiofrequency emission. Both observations suggest that the radiofrequency emissions come from the nervous system. RF frequency and magnetic field dependence are consistent with RF emission being related to electron Zeeman energy. Since the RF emission occurs without external energy input, its energy must come from cell metabolism.We propose that RF emissions are due to in vivo spin-polarised cellular electron currents. We suggest that spin-polarised currents relax radiatively to equilibrium at the Larmor frequency and are detected under our experimental conditions (resonator cavity and lock-in detection). We invite scrutiny of our methods and results, aim to elicit theorists interest in this novel phenomenon, and encourage replication in this and other preparations.

description: We discuss the Noeckel model of an open quantum dot, i.e., a straight hard-wall channel with a potential well. If this potential depends on the longitudinal variable only, there are embedded eigenvalues which turn into resonances if the symmetry is violated, either by applying a magnetic field or by deformation of the well. For a weak symmetry breaking we derive the perturbative expansion of these resonances. We also deduce a sufficient condition under which the discrete spectrum of such a system (without any symmetry) survives the presence of a strong magnetic field. It is satisfied, in particular, if the dot potential is purely attractive.

description: Measurements of the rf penetration depth λ(T,H,θ) are used to study the superconducting order parameter, vortex dynamics in the mixed state and delineate critical fields in the borocarbide superconductor YNi_2B_2C. The lower critical field has an anomalous T dependence, H_{c1}(T)=1.12[1-(T/T_c)] kOe, which is however consistent with independent superfluid density measurements at microwave frequencies. The vortex response is dominated by viscous flux flow, indicative of extremely weak pinning, and is parametrized by a field scale H_{c2,eff}. The angular dependence of the vortex contribution λ(θ) is in good agreement with the Coffey-Clem model. Structure is seen in the depairing transition in the vicinity of the upper critical field, with the existence of well-defined critical fields H_{c2a}, H_{c2b} and H_{c2c}, with the vortex field scale H_{c2,eff} closest to H_{c2b}. Overall the measurements indicate that YNi_2B_2C has a rich and unusual field dependence of its transport parameters.

How Artists Teach Leadership: Eight Portraits of Artist-Educators
Creators: Bang, April Hyoeun
Publisher: name: Columbia University
Year: 2020
Subjects: Leadership--Study and teaching
Educational leadership

description: This dissertation explored how eight artists who are also faculty in academic institutions and adult professional development programs teach leadership. As such, the purpose of this study was to understand to what extent and how these self-defined artists who also teach leadership in academic and professional development settings draw from and integrate their roles, skills, experiences, learning, and ways of making meaning as artists to facilitate leadership learning among adults. By doing so, this research sought to move beyond existing technical and conceptual knowledge of arts-based methods in leadership teaching to learning more about specific artists who have inspired or used such methods. Using the method of portraiture embedded in a qualitative exploratory interview study with narrative inquiry, this study reveals an aesthetic approach to research and presents narratives of eight artist-educators in the form of portraits. Portraits were analyzed thematically using a procedure of cross-portrait analysis. Four conclusions emerged from the analysis. These include evidence of participants’ greater integration or interdependence of artist-educator identities and roles in later stages of one’s teaching career, experience of some degree or form of transformation in personal learning journeys with art, emphasis on experiential learning as an essential aspect of teaching, and advice to emerging artist-educators to embrace their artistic ways of being and knowing and integrate art into their teaching. Several recommendations for future research and practice are offered along with concluding reflections.

description: This thesis investigates the diachronic behaviour of relative clauses across a broad sample of constructions from genetically and geographically diverse languages. Previous studies of change in relative clause constructions have most frequently been restricted to individual languages or language families. By comparing such studies with each other and with the historical records of languages that have less commonly been the focus of diachronic syntactic works, I examine the strength of evidence for developments that are predicted by earlier literature to be "e;natural"e; or even "e;universal"e; pathways of change (for example, various sources of relative clause markers, the development of hypotaxis out of parataxis, shift from prenominal to postnominal relative clause position). I also look for evidence of changes that synchronic typological studies of relative clause constructions might lead us to expect to find (i.e., diachronic variation in the same parameters by which relative clause types distinguish themselves synchronically). I conclude that the sources of relative clause markers and the results of the extensions of these markers into other constructions are more varied then has generally been thought to be the case, including, for example, such sources as classifiers and discourse markers. Changes in other features of relative clauses, however, such as verb forms, embeddedness, and the relative position of the relative clause and its head tend to be remarkably stable over long periods of time. The factor that appears to have the greatest influence on whether changes in these otherwise stable features do occur is language contact. Features of relative clauses, markers, and even entire constructions can be copied from other languages, competing with pre-existing constructions until in some cases one replaces the other, and in others the two are redistributed according to considerations such as restrictiveness, animacy, case role or similar. These results point to the importance of incorporating the effects of language contact into models of language change rather than viewing contact situations as exceptional. There are also implications for the definition of relative clauses, their syntactic structures, and the relationships between the different"e;subtypes"e; of this construction.
How Broken English Made Me Whole: Exploring Race, New Literacies, and Social Justice Within a Youth Participatory Action Research Framework

description: This critical ethnographic study investigated an afterschool Youth Participatory Action Research (YPAR) space that seeks to develop New Literacies and academic literacies in urban youth between the ages of 13-19. Utilizing a sociocultural lens, which asserts that literacy is a social practice (Gee, 1991), I examined the racial and literate identities of research participants who self-identify as Black and explored the potential of this participatory space to develop their literate identities and to broaden their critical meta-awareness. My findings suggest that prioritizing the Social Dimension of literacy is urgent for Black students in the classroom, that culturally sustaining literacies can have a powerful iterative relationship with academic literacies in the classroom, and that YPAR instruction must more intentionally attend to the role of literacy in youth qualitative inquiry.

description: In heterostructures consisting of atomically thin crystals layered on top of one another, lattice mismatch or rotation between the layers results in long-wavelength moiré superlattices. These moiré patterns can drive significant band structure reconstruction of the composite material, leading to a wide range of emergent phenomena including superconductivity, magnetism, fractional Chern insulating states, and moiré excitons. Here, we investigate monolayer graphene encapsulated between two crystals of boron nitride (BN), where the rotational alignment between all three components can be varied. We find that band gaps in the graphene arising from perfect rotational alignment with both BN layers can be modified substantially depending on whether the relative orientation of the two BN layers is 0 or 60 degrees, suggesting a tunable transition between the absence or presence of inversion symmetry in the heterostructure. Small deviations ($<1^{\circ}$) from perfect alignment of all three layers leads to coexisting long-wavelength moiré potentials, resulting in a highly reconstructed graphene band structure featuring multiple secondary Dirac points. Our results demonstrate that the interplay between multiple moiré patterns can be utilized to controllably modify the electronic properties of the composite heterostructure.

description: The ground state properties of interacting Bose gases in external potentials, as considered in recent experiments, are usually described by means of the Gross-Pitaevskii energy functional. We present here the first proof of the asymptotic exactness of this approximation for the ground state energy and particle density of a dilute Bose gas with a positive interaction.

Phase Segregation Dynamics in Particle Systems with Long Range Interactions I: Macroscopic Limits

description: We present and discuss the derivation of a nonlinear non-local integro-differential equation for the macroscopic time evolution of the conserved order parameter of a binary alloy undergoing phase segregation. Our model is a d-dimensional lattice gas evolving via Kawasaki exchange dynamics, i.e. a (Poisson) nearest-neighbor exchange process, reversible with respect to the Gibbs measure for a Hamiltonian which includes both short range (local) and long range (nonlocal) interactions. A rigorous derivation is presented in the case in which there is no local interaction. In a subsequent paper (part II), we discuss the phase segregation phenomena in the model. In particular we argue that the phase boundary evolutions, arising as sharp interface limits of the family of equations derived in this paper, are the same as the ones obtained from the corresponding limits for the Cahn-Hilliard equation.

title: Living in the Enduring 2015 “Refugee Crisis”: The Perspectives of Lesvos’ Local Populations
Creators: name: Sarantidis, Dimos
Publisher: name: The Open University
Year: 2021

description: In this thesis I focus on the ongoing consequences of the 2015 “refugee crisis” for the local populations of the Greek island of Lesvos, whose voices have been overlooked by various intervening state and non-state actors. A key contribution of this work is its focus on the voices and concerns of local populations, which offers a new analytical lens for exploring the refugee crisis. Drawing on a qualitative, field-based research on Lesvos I explore why and how a phenomenon that was initially framed as a crisis and a temporary emergency became enduring and mundane. I also examine how this protracted and exceptional situation affected locals’ everyday lives by amplifying pre-existing problems related to the Greek financial crisis. In considering the various actors that have intervened on Lesvos, I explore their roles and interactions with locals in order to understand how these relationships play out on the ground. By using the perspective of locals, I am seeking to shed more light on the impact of certain interventions. In that respect, I explore how the endurance of the state of emergency impacted regular democratic procedures on Lesvos as well as Greek state sovereignty. I found that, first, the impact of the refugee crisis needs to be analysed in conjunction with the lasting effects of the financial crisis. This “crisis within a crisis” created a suffocating environment for locals, with various economic, social, psychological, and environmental implications. Second, I found that the various interventions and exceptional policies on Lesvos have become normalised. Lesvos has become an exceptional space where the rule of law is systematically violated in the name of crisis, emergency, humanitarianism and security. Local populations, in turn, have found themselves being abandoned by law, because the border regime policies are devoid of democratic legitimacy and public contest. Third, various intervening actors contributed to enabling exceptional policies on the ground. Humanitarian actors’ dependence on donor funding has made them align with certain interests and agendas. This frequently resulted in silencing injustices that the EU border policies produce and gave space for exceptional political agendas to be embedded locally. Finally, I found that the “state of exception” in Greece and Lesvos during the past 10 years has resulted in the escalation of an already established “crypto-colonial” context, which expresses itself in overt ways, with political, economic and discursive components.
