description: Topological states enable robust transport within disorder-rich media through integer invariants inextricably tied to the transmission of light, sound, or electrons. However, the challenge remains to exploit topological protection in a length-scalable platform such as optical fibre. We demonstrate, through both modelling and experiment, optical fibre that hosts topological supermodes across multiple light-guiding cores. We directly measure the photonic winding-number invariant characterising the bulk and observe topological guidance of visible light over metre length scales. Furthermore, the mechanical flexibility of fibre allows us to reversibly reconfigure the topological state. As the fibre is bent, we find that the edge states first lose their localization and then become relocalised due to disorder. We envision fibre as a scalable platform to explore and exploit topological effects in photonic networks.

description: We propose a metamaterial to realize true electromagnetically induced transparency (EIT), where the incidence of an auxiliary electromagnetic wave called the control wave induces transparency for a probe wave. The analogy to the original EIT effect in an atomic medium is shown through analytical and numerical calculations derived from a circuit model for the metamaterial. We performed experiments to demonstrate the EIT effect of the metamaterial in the microwave region. The width and position of the transparent region can be controlled by the power and frequency of the control wave. We also observed asymmetric transmission spectra unique to the Fano resonance.

description: If the final position of a team is already secured independently of the outcomes of the remaining games in a round-robin tournament, it might play with little enthusiasm. This is detrimental to attendance and can inspire collusion and match-fixing. We demonstrate that tie-breaking rules might affect the occurrence of such a situation. Its probability is quantified via simulations for the four groups of the 2022/23 UEFA Nations League A under two well-established tie-breaking rules, goal difference and head-to-head records. In these home-away round-robin contests with four teams and 12 matches, the competitiveness of the final four games can be promoted by giving priority to goal difference, which reduces the chance of a fixed position in the group ranking by at least two and usually five percentage points in the last round. Our findings, supported by sensitivity analysis in a theoretical model, provide important lessons on how to design ranking systems.

description: The geometric framework for the Hamilton-Jacobi theory developed in previous works is extended for multisymplectic first-order classical field theories. The Hamilton-Jacobi problem is stated for the Lagrangian and the Hamiltonian formalisms of these theories as a particular case of a more general problem, and the classical Hamilton-Jacobi equation for field theories is recovered from this geometrical setting. Particular and complete solutions to these problems are defined and characterized in several equivalent ways in both formalisms, and the equivalence between them is proved. The use of distributions in jet bundles that represent the solutions to the field equations is the fundamental tool in this formulation. Some examples are analyzed and, in particular, the Hamilton-Jacobi equation for non-autonomous mechanical systems is obtained as a special case of our results.

Starving for Surgery: An Integrative Review
Creators: name: Langevin, Brooke
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Background: Perioperative Fasting, or NPO (nil per os) status is a widespread preprocedural order to prevent intraoperative aspiration. “NPO” refers to the time a patient is without any oral liquids or solids before a procedure. In most healthcare settings, NPO after midnight is common practice. However, numerous evidence-based studies suggest the routine of prolonged NPO leads to numerous adverse side effects and surgical complications. Purpose: The purpose of this integrative literature review was to synthesize and evaluate studies to determine the extent of preoperative fasting implemented with adult patients undergoing elective procedures. Moreover, the timing of how soon before a procedure can a patient safely consume oral liquids or solids was examined. Methods: A search of the literature was conducted, using CINAHL, Pubmed, and Google Scholar. The search resulted in twenty-three articles relevant and advantageous for the purpose of this review. Results: Three themes commonly found in the articles include: 1) Patients are fasting longer than
guidelines recommend, 2) patients allowed preoperative intake 2 hours prior to surgery experienced less preoperative and postoperative hunger and thirst, nausea and vomiting, and surgical complications, 3) postoperative hospital stay increases with increased preoperative fasting time.

description: Starting from a product initial state, equal-time correlations in nonrelativistic quantum lattice models propagate within a lightcone-like causal region. The presence of entanglement in the initial state can modify this behavior, enhancing and accelerating the growth of correlations. In this paper we give a quantitative description, in the form of Lieb-Robinson-type bounds on equal-time correlation functions, of the interplay of dynamics vs. initial entanglement in quantum lattice models out of equilibrium. We test the bounds against model calculations, and also discuss applications to quantum quenches, quantum channels, and Kondo physics.

description: The existence of a fundamental length scale in Nature is a common prediction of distinct quantum gravity models. Discovery of such would profoundly change current knowledge of quantum phenomena and modifications to the Heisenberg uncertainty principle may be expected. Despite the attention given to this possibility in the past decades, there has been no common framework for a systematic investigation of so called generalized uncertainty principles (GUP). In this work we provide such framework in the context of nonrelativistic quantum mechanics. Our approach is based on very few assumptions: there is a fundamental length scale, space isotropy, invariance under parity and time reversal transformations, and symmetricity of the position and momentum operators. We show simple dimensional analysis allows for building a unified framework containing any isotropic generalized uncertainty principle (iGUP) and discuss some popular GUP models in this context after elaborating on relevant theoretical aspects of the framework. At last, we translate current bounds on three often investigated GUP models into bounds on parameters of such unified iGUP framework.

Psychosocial Support for Healthy Siblings of Pediatric Oncology Patients

description: Healthy siblings of children with cancer are impacted by the diagnosis in a way not often recognized or understood. The sudden changes and range of emotions experienced can lead to a risk of distress and long-term negative effects for healthy siblings as they may internalize stress, externalize stress, or express stress physically (Zegaczewski et. al., 2015). This paper explores the unmet needs of healthy siblings, psychosocial impact of the diagnosis, and the actions being taken in order to increase positive outcomes through a comprehensive review of the literature and a closer look into resources provided by UNC Hospitals’ Child Life Specialists. Common needs, as reported by the Child Life Specialist interviewed, are related to school behaviors, signs of regression, separation anxiety, and financial stress for the sibling. UNC Hospitals offers resources by means of Child Life Specialists to support healthy siblings through the cancer experience, using interactive books, creative communication methods, and recreational opportunities. In conjunction, the literature and the resources offered at UNC Hospitals indicate that there are increased efforts to provide support for siblings. However, there are still a number of barriers to be overcome, including lack of access to siblings, lack of direct funding, and lack of general awareness. To decrease risk for maladaptation and negative psychosocial outcomes, healthcare professionals must be educated on sibling impact and use an interdisciplinary approach to provide appropriate supportive interventions.
title: Distributed graph partitioning to optimise collaborative filtering algorithms

Publisher: name: University of Liverpool Repository
Year: 2027

description: Graphs provide intuitive abstraction for a lot of the problems. But with advent of data getting bigger it is becoming increasingly difficult to operate big data on a single machine. Hence, big data requires distributed computing which means data could be split across multiple machines. However, that requires classical graph based algorithms and techniques, which are designed for a single machine, to be applied in a distributed manner. One area where this big data challenge is demonstrated is in the gaming industry where millions of players need to be matched together in real-time using collaborative filtering algorithms. Model based collaborative filtering algorithms are slower than memory based collaborative filtering algorithms, but have higher accuracy in terms of prediction and matching. Therefore graph based algorithms and graph partitioning techniques must be devised so that model collaborative filtering can be applied. One way to improve the efficiency of such algorithms is to distribute the data on a cluster of machines so that these algorithms could be executed in almost real-time. The research presented in this thesis is directed at issues related to graph partitioning to improve the efficiency of collaborative filtering algorithms by improving multi-level graph partitioning, spectral graph partitioning and partitioning based on minimum spanning trees, using publicly available data-set movie-lens and synthetically generated data-set based of driveClub game. Synthetically generated data-set is used in absence of actual data-set for driveClub game. However, publicly available data-set of movie-lens has been used to demonstrate the generation of synthetic data-set is representative with respect to original data-set when used for collaborative filtering algorithms.

description: We study the dissociation of Feshbach molecules in ultracold Fermi gases with spin-orbit (SO) coupling. Since SO coupling can induce quantum transition between the Feshbach molecules and the fully polarized Fermi gas, the Feshbach molecules can be dissociated by the SO coupling. We experimentally realized this new type of dissociation in ultracold gases of 40K atoms with SO coupling created by Raman beams, and observed that the dissociation rate is highly non-monotonic on both the positive and negative Raman-detuning sides. Our results show that the dissociation of Feshbach molecules can be controlled by new degrees of freedoms, i.e., the SO-coupling intensity or the momenta of the Raman beams, as well as the detuning of the Raman beams.

Determinants of Deposit Mobilization and Related Costs of Commercial Banks in Ethiopia
Creators: name: Giragn Garo
Publisher: name: Zenodo
Year: 2015

description: The objective of commercial banks in Ethiopia is to make profits and thus satisfy the needs of their respective owners. The making of profits and even staying on board of these conventional banks depend on the strategies adopted by each bank to mobilize deposits from the public that is an input to earn income for most conventional banks. In order to make good strategies, however, the banks should know what factors determine the deposit mobilization activity in the real world. This paper then explores the theoretical as well as empirical analysis of those factors having an impact on deposit volume in banks and even assesses which ones are more significant or less significant. To do the practical investigation in terms of commercial banks in Ethiopia, the researcher collected the relevant data from annual reports of twelve years (2001/2-2012/13) and from questionnaires and interviews made to senior bank officers of seven banks. The data is analyzed through the econometric analysis using SPSS software.

Internalizing Symptoms and Ethnic-Racial Identity Development During Adolescence
Creators: name: Ta, Dan

Year: 2020

description: Most research examining the development of ethnic-racial identity has focused on peer and family predictors, but there is limited literature regarding the effect that psychological stress may have in the development of ethnic identity commitment and exploration among adolescents. Internalizing symptoms such as social anxiety and depression are important factors to consider during the development of ethnic-racial identity. The current study analyzed associations among ethnic-racial identity, social anxiety, depressive symptoms, social preference, and popularity within a sample of African American and Latinx adolescents. Higher social anxiety was longitudinally associated with lower ethnic-racial identity commitment over time, suggesting that psychological distress may affect how ethnic-racial identity develops.

description: We obtain new equitightness and $C([0,T];L^p(\mathbb{R}^N))$-convergence results for finite-difference approximations of generalized porous medium equations of the form $$ \partial_tu-\mathfrak{L}[φ(u)]=g\qquad\text{in $\mathbb{R}^N\times(0,T)$}, $$ where $φ:\mathbb{R}\to\mathbb{R}$ is continuous and nondecreasing, and $\mathfrak{L}$ is a local or nonlocal diffusion operator. Our results include slow diffusions, strongly degenerate Stefan problems, and fast diffusions above a critical exponent. These results improve the previous $C([0,T];L_{\text{loc}}^p(\mathbb{R}^N))$-convergence obtained in a series of papers on the topic by the authors. To have equitightness and global $L^p(\mathbb{R}^N)$-convergence, some additional restrictions on $\mathfrak{L}$ and $φ$ are needed. Most commonly used symmetric operators $\mathfrak{L}$ are still included: the Laplacian, fractional Laplacians, and other generators of symmetric Lévy processes with some fractional moment. We also discuss extensions to nonlinear possibly strongly degenerate convection-diffusion equations.

description: We consider the generalization of the "spinor approach" to the Lorentzian case, in the context of 3d loop quantum gravity with cosmological constant $Λ=0$. The key technical tool that allows this generalization is the recoupling theory between unitary infinite-dimensional representations and non-unitary finite-dimensional ones, obtained in the process of generalizing the Wigner-Eckart theorem to SU(1,1). We use SU(1,1) tensor operators to build observables and a solvable quantum Hamiltonian constraint, analogue of the one introduced by V. Bonzom and his collaborators in the Euclidean case (with both $Λ=0$ and $Λ\neq0$). We show that the Lorentzian Ponzano-Regge amplitude is solution of the quantum Hamiltonian constraint by recovering the Biedenharn-Elliott relation (generalized to the case where unitary and non-unitary SU(1,1) representations are coupled to each other). Our formalism is sufficiently general that both the Lorentzian and the Euclidean case can be recovered (with $Λ=0$).

description: The advent of autonomous driving and advanced driver assistance systems necessitates continuous developments in computer vision for 3D scene understanding. Self-supervised monocular depth estimation, a method for pixel-wise distance estimation of objects from a single camera without the use of ground truth labels, is an important task in 3D scene understanding. However, existing methods for this task are limited to convolutional neural network (CNN) architectures. In contrast with CNNs that use localized linear operations and lose feature resolution across the layers, vision transformers process at constant resolution with a global receptive field at every stage. While recent works have compared transformers against their CNN counterparts for tasks such as image classification, no study exists that investigates the impact of using transformers for self-supervised monocular depth estimation. Here, we first demonstrate how to adapt vision transformers for self-supervised monocular depth estimation. Thereafter, we compare the transformer and CNN-based architectures for their performance on KITTI depth prediction benchmarks, as well as their robustness to natural corruptions and adversarial attacks, including when the camera intrinsics are unknown. Our study demonstrates how transformer-based architecture, though lower in run-time efficiency, achieves comparable performance while being more robust and generalizable.

description: We propose a holistic framework for constructing sensitivity measures for any elicitable functional $T$ of a response variable. The sensitivity measures, termed score-based sensitivities, are constructed via scoring functions that are (strictly) consistent for $T$. These score-based sensitivities quantify the relative improvement in predictive accuracy when available information, e.g., from explanatory variables, is used ideally. We establish intuitive and desirable properties of these sensitivities and discuss advantageous choices of scoring functions leading to scale-invariant sensitivities. Since elicitable functionals typically possess rich classes of (strictly) consistent scoring functions, we demonstrate how Murphy diagrams can provide a picture of all score-based sensitivity measures. We discuss the family of score-based sensitivities for the mean functional (of which the Sobol indices are a special case) and risk functionals such as Value-at-Risk, and the pair Value-at-Risk and Expected Shortfall. The sensitivity measures are illustrated using numerous examples, including the Ishigami--Homma test function. In a simulation study, estimation of score-based sensitivities for a non-linear insurance portfolio is performed using neural nets.
Caregivers’ Knowledge, Beliefs, and Socialization Behavior Regarding Children’s Emotional Development

description: Emotion socialization guides children’s ability to recognize, understand, express, and respond to emotions. This emotional competence is an integral part of children’s socio-emotional development and is informed by caregivers’ emotion socialization practices, including discussion of emotions. Comprised of a socioeconomically and racially diverse subsample (N=107) from the Play & Grow project, this study uses behavioral coding methodology to analyze caregivers’ use of emotion-directed language with their 24-month old children. The Knowledge of Infant Development Inventory (KIDI) and Parental Emotion-Related Beliefs Questionnaire (PERB) are also used to assess caregivers’ knowledge and beliefs about emotions and child development. Correlational tests and a logistic regression were performed to analyze relations between caregivers’ knowledge/beliefs and their socialization behavior. Furthermore, cross-tabulations and chi-squared analyses were performed to evaluate caregivers’ differential emotion socialization with sons and daughters. Results indicated a significant, but not predictive, relationship between knowledge of infant development and positive emotion-directed language use, and caregivers used significantly more positive and negative emotion-directed language with sons compared to daughters. However, all other findings were nonsignificant. This research suggests a discrepancy between caregivers’ knowledge/beliefs and their parenting behavior, and it yields unique insight to how caregivers are differentially socializing boys and girls about emotions.

description: While several experiments claim that two-level system (TLS) defects in amorphous surfaces/interfaces are responsible for energy relaxation in superconducting resonators and qubits, none can provide quantitative explanation of their data in terms of the conventional noninteracting TLS model. Here a model that interpolates between the interacting and noninteracting TLS loss tangent is proposed to perform numerical analysis of experimental data and extract information about TLS parameters and their distribution. As a proof of principle, the model is applied to TESLA cavities that contain only a single lossy material in their interior, the niobium/niobium oxide interface. The best fits show interacting TLSs with a sharp modulus of electric dipole moment for both thin (5 nm) and thick (100 nm) oxides, indicating that the TLSs are "atomic" instead of "glassy". The proposed method can be applied to other devices with multiple material interfaces and substrates, with the goal of elucidating the nature of TLSs causing energy loss in resonators and qubits.

THE EFFECT OF OBESITY ON THE IMMUNE RESPONSE TO INFLUENZA VACCINATION IN THE ELDERLY

Year: 2020

description: Each year, influenza results in 3 to 5 million cases of severe illness and between 290,000 to 650,000 deaths globally. Elderly and obese individuals are at increased risk of infection, illness, and death. Elderly individuals ( 65 years) exhibit a decline in immune function which renders them more susceptible to influenza. Obese individuals (BMI  30 kg/m2) exhibit impairments in adaptive immunity which also puts them at high risk. Given the anticipated rise in the proportion of the global population that constitutes both elderly and obese, I investigated the extent to which aging and obesity, together, impact the immune response to influenza vaccination. In this study, the hemagglutination inhibition (HAI) assay was performed to quantify antibodies to the influenza virus in sera of vaccinated elderly obese and elderly non-obese individuals. The results of this study do not suggest that obesity impairs influenza vaccination responses in the elderly.

description: Electron-lattice interactions play a prominent role in quantum materials, making a deeper understanding of direct routes to phonon-mediated high-transition-temperature ($T_{\mathrm{c}}$) superconductivity desirable. However, it has been known for decades that weak electron-phonon coupling gives rise to low values of $T_{\mathrm{c}}$, while strong electron-phonon coupling leads to lattice instability or formation of bipolarons, generally assumed to be detrimental to superconductivity. Thus, the route to high-$T_{\mathrm{c}}$ materials from phonon-mediated mechanisms has heretofore appeared to be limited to raising the phonon frequency as in the hydrogen sulfides. Here we present a simple model for phonon-mediated high-$T_{\mathrm{c}}$ superconductivity based on superfluidity of light bipolarons. In contrast to the widely studied Holstein model where lattice distortions modulate the electron's potential energy, we investigate the situation where lattice distortions modulate the electron hopping. This physics gives rise to small-size, yet light bipolarons, which we study using an exact sign-problem-free quantum Monte Carlo approach, demonstrating a new route to phonon-mediated high-$T_\mathrm{c}$ superconductivity. We find that $T_\mathrm{c}$ in our model generically and significantly exceeds typical upper bounds based on Migdal-Eliashberg theory or superfluidity of Holstein bipolarons. The key ingredient in this bipolaronic mechanism that gives rise to high $T_\mathrm{c}$ is the combination of light mass and small size of bipolarons. Our work establishes principles towards the design of high-$T_{\mathrm{c}}$ superconductors via functional material engineering.

description: In experiments the two-dimensional systems are realized mainly on solid substrates which introduce quenched disorder due to some inherent defects. The defects of substrates influence the melting scenario of the systems and have to be taken into account in the interpretation of the experimental results. We present the results of the molecular dynamics simulations of the two dimensional system with the core-softened potential in which a small fraction of the particles is pinned, inducing quenched disorder.The potentials of this type are widely used for the qualitative description of the systems with the water-like anomalies. In our previous publications it was shown that the system demonstrates an anomalous melting scenario: at low densities the system melts through two continuous transition in accordance with the Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory with the intermediate hexatic phase, while at high densities the conventional first order melting transition takes place. We find that the well-known disorder-induced widening of the hexatic phase occurs at low densities, while at high density part of the phase diagram random pinning transforms the first-order melting into two transitions: the continuous KTHNY-like solid-hexatic transition and first-order hexatic-isotropic liquid transition.

These facilities are poorly regulated and often placed in high flood zones. Past studies have shown that these lagoons frequently overflow and contaminate local groundwater supplies. Public water systems are legally required to test for indicators of contamination, specifically total coliforms and Escherichia coli, however, there is a lack of knowledge surrounding the level of contamination in private well water systems as they are not required to be tested. In order to address these shortcomings, the NSF project in the Gillings School of Public Health investigated the extent of fecal contamination in private water systems. One method that was used to analyze the levels of contamination in private water systems was the EPA’s Method 1604: Total Coliforms and Escherichia Coli in Water by Membrane Filtration Using a Simultaneous Detection Technique. While this method has shown to be useful for determining contaminants in groundwater, preliminary data collected in our laboratory suggest there are shortcomings. While using this method, indicators of contamination continued to appear after the protocol’s recommended incubation period. After studying the effect of various incubation periods, it appears that 48 hours, rather than the recommended 24 hours, is more appropriate for measuring the extent of contamination in private drinking water systems. These findings suggest that a revision may be needed in the EPA’s protocol for membrane filtration, especially in the context of evaluating the safety of water for human consumption.

description: In this work, we have discussed a spatially homogeneous and anisotropic Bianchi type-I space-time in the presence of Barrow holographic dark energy (infrared cut-off is the Hubble's horizon) proposed by Barrow recently (Physics Letters B 808 (2020): 135643) and matter in the framework of $f(Q)$ gravity where the non-metricity $Q$ is responsible for the gravitational interaction for the specific choice of $f(Q)=λQ^{2}$ (where $λ<0$ is a constant). To find the exact solutions to the field equations we consider the deceleration parameter $q$ is a function of the Hubble's parameter $H$ i.e. $q=b-\frac{n}{H}$ (where $b$ and $n$ are constants). We have studied the physical behavior of important cosmological parameters such as the EoS parameter, BHDE and matter density, skewness parameter, squared sound speed, and $ω_{B}-ω_{B}^{^{\prime }}$ plane. Also, we constrain the values of the model parameters $b$ and $n$ using $57$ Hubble's parameter measurements.

description: We establish a combinatorial counterpart of the Cohen-Macaulay duality on a class of curve singularities which includes algebroid curves. For such singularities the value semigroup and the value semigroup ideals of all fractional ideals satisfy axioms that define so-called good semigroups and good semigroup ideals. We prove that each good semigroup admits a canonical good semigroup ideal which gives rise to a duality on good semigroup ideals. We show that the Cohen-Macaulay duality and our good semigroup duality are compatible under taking values.

description: To artistically address the sustainability problems associated with trash, I designed and began production of an art installation comprised of functional musical instruments built out of found and reclaimed objects, photographs of landfills, and interactive audio recordings of these instruments. I was unable to complete this installation due to COVID-19. Instead, I built another instrument at home and created a virtual exhibit. The goal of this work is both to reaffirm that trash never goes away, and to provoke emotions of regret and longing for the world we have all damaged through our wastefulness.
Revealing Hidden Coherence in Partially Coherent Light

description: Coherence and correlations represent two related properties of a compound system. The system can be, for instance, the polarization of a photon, which forms part of a polarization-entangled two-photon state, or the spatial shape of a coherent beam, where each spatial mode bears different polarizations. Whereas a local unitary transformation of the system does not affect its coherence, global unitary transformations modifying both the system and its surroundings can enhance its coherence, transforming mutual correlations into coherence. The question naturally arises of what is the best measure that quantifies the correlations that can be turned into coherence, and how much coherence can be extracted. We answer both questions, and illustrate its application for some typical simple systems, with the aim at illuminating the general concept of enhancing coherence by modifying correlations.

description: In this work, we consider the mathematical theory of wind generated water waves. This entails determining the stability properties of the family of laminar flow solutions to the two-phase interface Euler equation. We present a rigorous derivation of the linearized evolution equations about an arbitrary steady solution, and, using this, we give a complete proof of the instability criterion of Miles. Our analysis is valid even in the presence of surface tension and a vortex sheet (discontinuity in the tangential velocity across the air--sea interface). We are thus able to give a unified equation connecting the Kelvin--Helmholtz and quasi-laminar models of wave generation.
title: INTEGRATION OF TRANSBORDER ETHNIC COMMUNITIES INTO THE KIN-STATE AND HOME-STATE. The case of the Croat community in Herzegovina
Creators: name: Subasic, Mate
Publisher: name: University of Liverpool Repository

description: The relevance of transborder ethnic communities has increased significantly in the last three decades, but the literature has not yet looked at the long-term implications of the kin-state relations. This thesis fills this gap by developing a long-term model of kin-state relations to investigate how the dynamics of the kin-state relations impact the integration of the transborder ethnic communities in the long-term. The model first identifies changing dynamics of kin-state relations at the macro-level, and then, at the micro-level, establishes how the changing dynamics impact integration of individuals into their kin-state and home-state. By applying the bottom-up approach, integration is conceptualised through meanings individuals assign to the concepts of territory, border, and citizenship. Methodologically a single case study, the thesis applies interviews and focus group methods. The case of Croats from Herzegovina had been strategically chosen for the longevity and complexity of the kin-state relations between them and Croatia and Bosnia and Herzegovina. At the macro-level, the thesis demonstrates, first, that the kin-state relations can change from conflict-conducive towards accommodative. In this process, the kin-state policies become normalised within the kin-state. Second, the divided statehood remains a source of perpetual competing claims within the home-state and enables the transborder ethnic community to utilise kin-minority and kin-majority policies, regardless of their constitutional status. Third, the thesis demonstrates how the kin-state can expand its policies once it enters the EU by aligning the EU’s policies towards prospective states where the transborder community resides. At the micro-level, the thesis demonstrates how changing dynamics of the kin-state relations impact transborder integration into the kin-state and home-state. Improved border management between Croatia and BiH amplified the sense of separation from the kin-state but also the sense of unity for the recognition the Croats in Herzegovina receive when they cross the border. The meanings participants assign to citizenship changed too – in relation to the perception of inclusion into the kin-state, the type and extent of opportunities that kin-stare provides, and the routinisation of citizenship acquisition practice. The changes then inform their experiences across the kin-state and home-state and exacerbate their feeling of in-betweenness – the transborder ethnic community seeks recognition of their integration into the home-state and the kin-state that is not mutually exclusive.
