description: Σκοπός της παρούσας εργασίας ήταν η μελέτη των ψηφιδωτών παραστάσεων των αψίδων των μνημείων της Ρώμης από τον 9ο μέχρι τον 12ο αιώνα. Στο πρώτο μέρος εξετάσαμε αναλυτικά και με χρονολογική σειρά την κάθε παράσταση. Αρχικά προβήκαμε σε μία γενική περιγραφή και ακολούθως αναλύσαμε τα επιμέρους εικονογραφικά στοιχεία σε συνάρτηση με το ιστορικό πλαίσιο, τα θεολογικά συμφραζόμενα, αλλά και διάφορα εικονογραφικά παράλληλα. Στο δεύτερο μέρος προβήκαμε σε μία γενικότερη θεώρηση του ψηφιδωτού διακόσμου των κτηρίων της Ρώμης του 9ου και του 12ου αιώνα, παραθέτοντας πληθώρα πατερικών χωρίων, καίριας σημασίας για την ερμηνεία εικονογραφικών μοτίβων κοινών σε αρκετές παραστάσεις του 9ου αιώνα, αλλά και εξετάζοντας το ζήτημα του στυλ και της ταυτότητας των ψηφοθετών/εργαστηρίων.
description: The aim of the present thesis was the study of apse mosaic representations in Rome dating from the 9th to the 12th centuries. In the first part, we thoroughly examined, according to chronological order, each representation. We initially did a general description, and we subsequently analyzed each iconographic element in relation to the historical and theological context, as well as various iconographic parallels. In the second part, we did a more general survey of the mosaic decorations of the buildings in Rome dating to the 9th and the 12th centuries, by citing plenty of patristic texts, which are of great importance for the interpretation of iconographic motifs that are common among many representations of the 9th century, and also by examining the style and the identity of the mosaicists/workshops.

Nutrition and Health in the Piedmont of North Carolina and Virginia: A Bioarchaeological Study
Creators: name: Rouse, Carson Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This study focuses on changes in nutrition and health in three past populations that
inhabited the Piedmont of North Carolina and Virginia. The people who lived at the three
localities - Town Creek, Stockton, and Fredricks - date to the late prehistoric and early
colonial time periods. In order to reconstruct the health of these populations, I examined
forty-nine individuals to estimate age and sex, and for lesions that serve as evidence of
disease or nutritional deficiency. The indicators of health fall into one of three categories:
oral health, dietary deficiencies, and general indicators of disease or stress. I specifically
looked for changes to oral environment including alveolar infections, tooth loss, and cavities.
In order to assess dietary deficiencies, I observed indicators of scurvy, rickets and anemia
which are often manifested in lesions on specific bones. Finally, other indicators of health
such as osteomyelitis and periosteal reactions were noted as general indicators of health
insult. I hypothesize that populations inhabiting the North Carolina and Virginia Piedmont
became healthier after colonization due to shifts away from an agricultural diet that were
brought about by increasing mobility and economic changes associated with colonial
encounters.

description: In this paper we discuss the problem of decomposition for unbounded $2\times 2$ operator matrices by a pair of complementary invariant graph subspaces. Under mild additional assumptions, we show that such a pair of subspaces decomposes the operator matrix if and only if its domain is invariant for the angular operators associated with the graphs. As a byproduct of our considerations, we suggest a new block diagonalization procedure that resolves related domain issues. In the case when only a single invariant graph subspace is available, we obtain block triangular representations for the operator matrices.

Metagenomics of the Galapagos Marine Microbiome

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The Galapagos Islands are located in the eastern Pacific Ocean where several currents interact to create diverse marine environments. Heterotrophic bacteria control how much carbon is available to organisms at higher trophic levels; however, the compositions of the Galapagos microbiome and how differences in microbial community structure are driven by the diverse environmental conditions found among the islands are currently unknown. Environmental samples were collected from 18 stations across the islands and DNA was extracted and sequenced. The sequencing data was analyzed to estimate the relative and absolute cell abundance in each sample. Candidatus Pelagibacter and Synechococcus were the most abundant taxa across the majority of the stations. Distinct community compositions were found at stations located at the western side of the islands in 2016 when the La Nina strengthened the upwelling caused by the Equatorial Undercurrent in this region, suggesting that certain bacteria were selected for by the nutrient-rich environment. The findings provide insight into the microbial community compositions of the Galapagos marine environment and offer potential microbial markers for characterizing the physical environment.

description: The present bibliographic research consists of four chapters. Initially, an analysis of the significance of dialogue is conducted, which serves as the basis for all social interactions. Subsequently, the value of diplomacy in general and specifically cultural diplomacy is approached, referring to specific well-known historical examples that underpin this value of cultural diplomacy. Then, the tool of interreligious dialogue is discussed as part of cultural diplomacy, which in turn aims to create bridges of dialogue contributing to the peaceful coexistence of various religions and, by extension, to international security. At this point, dialogical actions are presented, and clarification is provided on what interreligious dialogue is not, addressing common concerns. The third chapter analyzes the dialogical example of the World Council of Churches, tracing its historical trajectory and referring to actions it has undertaken towards interreligious dialogue. Finally, a similar analysis is conducted in the fourth chapter for the Roman Catholic Church, approaching its historical journey in terms of dialogue and referring to dialogical initiatives that have been undertaken.

Different schemes are proposed with different speed limits that depend on the control capabilities. We also make use of trap rotations to create squeezed states without manipulating the trap frequencies.

description: In recent years, Artificial Intelligence (AI) has seen a remarkable surge in adoption in many everyday applications, primarily fueled by Machine Learning (ML) algorithms that rely on extensive data for model training. However, privacy constraints and the decentralization of data across various repositories, often constrained by data sharing limitations, present a significant challenge. To address this issue, Federated Learning (FL) techniques have emerged with the promise of facilitating collaborative model training across disparate devices or entities while offering better data privacy guarantees. While it is true that FL enhances data privacy, security concerns still remain, including privacy attacks that compromise the confidentiality of training data like attribute inference and even data reconstruction attacks. To strengthen the baseline privacy provided by FL, it is essential to research and develop novel privacy enhancement methods for Federated Learning. Our goal is to deliver a highly scalable, armored Federated AI service platform for researchers, enabling AI-powered studies of multi-site, siloed, cross-domain, cross-border European datasets with high privacy guarantees which comply with data privacy regulations such as the General Data Protection Regulation (GDPR). This paper explores how FL can be a useful tool for implementing collaborative training of ML models with privacy guarantees, focusing on the main challenges to be addressed to achieve an armored FL framework.

description: In a pioneering effort, Preston et al. reported that the colors of blue horizontal-branch (BHB) stars in the halo of the Galaxy shift with distance, from regions near the Galactic center to about 12 kpc away, and interpreted this as a correlated variation in the ages of halo stars, from older to younger, spanning a range of a few Gyrs. We have applied this approach to a sample of some 4700 spectroscopically confirmed BHB stars selected from the Sloan Digital Sky Survey to produce the first "chronographic map" of the halo of the Galaxy. We demonstrate that the mean de-reddened g$-$r color, , increases outward in the Galaxy from $-$0.22 to $-$0.08 (over a color window spanning [$-$0.3:0.0]) from regions close to the Galactic center to ~40 kpc, independent of the metallicity of the stars. Models of the expected shift in the color of the field BHB stars based on modern stellar evolutionary codes confirm that this color gradient can be associated with an age difference of roughly 2-2.5 Gyrs, with the oldest stars concentrated in the central ~15 kpc of the Galaxy. Within this central region, the age difference spans a mean color range of about 0.05 mag (~0.8 Gyrs). Furthermore, we show that chronographic maps can be used to identify individual substructures, such as the Sagittarius Stream, and overdensities in the direction of Virgo and Monoceros, based on the observed contrast in their mean BHB colors with respect to the foreground/background field population.

Behn and the Dilemma of Libertinism: Atheism, Conservativism, and Anxieties of Freethinking in Restoration England
Creators: name: Lesley, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The inclusion of Aphra Behn in Anthony Collins’ 1713 Discourse of Free-Thinking as the only female in a list of respected libertine thinkers calls into question traditional readings of Behn as solely a sexual libertine. While she certainly engages in controversial sexual and gendered philosophy, Collins considers her a part of a more broadly defined freethinking community of theological and classical inquiry. When Collins lists Behn in a sampling of writers that celebrated Thomas Creech’s 1683 translation of Lucretius’ De Rerum Natura, she joins the ranks of men such as Dr. Edward Bernard, Joshua Barnes, and the provost of King’s College, Dr. Adams (Collins 92). All of these men produced texts of interest for the freethinking community of the late sixteenth and early seventeenth century, from Bernard’s discussions of suicide in Donne’s Biathanatos to Barnes’ fictional utopian world of pygmies. Yet Collins does not know that Behn was unusually controversial in her treatment of Creech’s Lucretius. Her own commendatory poem underwent two editions, one of which was highly edited by Creech. Creech’s edits reveal that he was concerned with her celebration of the freedom of thought—a freedom that even Behn seems to recognize could lead to complex and even problematic theological inquiries.

description: Inspired by the present experimental status of charged charmonium-like states $Z_c^+$, the tetraquark states $[cu][\bar{c}\bar{d}]$ are systematically studied in a color flux-tube model with a multi-body confinement potential. The investigation indicates that charged charmonium-like states $Z_c^+(3900)$ or $Z_c^+(3885)$, $Z_c^+(3930)$, $Z_c^+(4020)$ or $Z_c^+(4025)$, $Z_1^+(4050)$, $Z_2^+(4250)$, and $Z_c^+(4200)$ can be uniformly described as tetraquark states $[cu][\bar{c}\bar{d}]$ with the quantum numbers $n^{2S+1}L_J$ and $J^P$ of $1^{3}S_1$ and $1^+$, $2^{3}S_1$ and $1^+$, $1^5S_2$ and $2^+$, $1^3P_1$ and $1^-$, $1^5D_1$ and $1^+$, and $1^3D_1$ and $1^+$, respectively. The predicted lowest charged tetraquark state $[cu][\bar{c}\bar{d}]$ with $0^+$ and $1^1S_0$ has a energy of $3780\pm10$ MeV in the model. The tetraquark states are compact three-dimensional spatial configurations similar to a rugby ball, the higher orbital angular momentum $L$ between the diquark $[cu]$ and antidiquark $[\bar{c}\bar{d}]$, the more prolate of the states. The multibody color flux-tube, a collective degree of freedom, plays an important role in the formation of those charge tetraquark states. However, the two heavier charged states $Z^+_c(4430)$ and $Z^+_c(4475)$ can not be explained as tetraquark states $[cu][\bar{c}\bar{d}]$ in this model approach.

An Investigation of How Cognitive Flexibility and Active-Coping Strategy Influence Pilots' Stress Level When Working in High-Risk Environment
Creators: name: Tianchai, Maneerat
Publisher: name: University of Southern Queensland
Year: 2022
Subjects: Aviation, Pilot, Resilience, Stress,Cognitive Flexibility, Active Coping Strategy

description: The aviation industry is a fast-paced and high-risk environment where a pilot is required to tolerate stressful circumstances to maintain appropriate safety standards for the operation of aircraft. Various safety management concepts have been implemented aiming to maximise pilot performance and minimise risk. Nevertheless, accidents occur, and these have disastrous impacts on the whole industry. Many documented aircraft accidents are related to human error, suggesting that some pilots may lack the ability to recover adequately from an unexpected situation. This lack of a suitable response indicates that the current most effective pilot training for operating an aircraft competently may be inadequate. Therefore, there may be additional training elements to be considered. One of these elements is the concept of 'resilience', which has gathered momentum recently with respect to pilot competency in a stressful environment. The aim of this thesis is to identify resilience factors that help to develop or improve pilots' resilience capability when working in the high-stress environment of flying an aeroplane. This research infers that cognitive flexibility and active coping strategies are important factors in strengthening and maintaining pilots' resilience. To determine whether cognitive flexibility and active coping strategies are capabilities of a resilient pilot, an assessment was executed in two separate studies. The collective findings from the two studies signify that cognitive flexibility and active coping strategies contribute to a resilient pilot. The group of professional airline pilots appeared to have higher cognitive flexibility than the group of 'Experienced in Flying Students' (EFS), and the EFSs in turn had higher cognitive flexibility than the group of 'Non-experience in Flying Students' (NFS). This trend also appeared in the engagement of active coping strategies. These capabilities were found to be strengthened through initial flight training and sustained through the ongoing training process. The findings from this research fully support that cognitive flexibility and active coping strategies are attributes of resilient pilots, and these capabilities should be developed and strengthened from the ab initio to the professional level, so that flight safety can be better assured.

Οι βασικές αρχές του οικοφεμινισμού αφορούν στην σύνδεση μεταξύ θηλυκού και φύσης, καθώς και στην καταπίεση και καταστροφή που αυτές υφίστανται από τις ανδροκρατούμενες δυνάμεις, οι οποίες καθόρισαν τον Δυτικό πολιτισμό (Quartarone, 2002, 147). Στον οικοφεμινισμό όλα συνίστανται από φυσικές και εννοιολογικές σχέσεις· ανθρώπινη και οικολογική πραγματικότητα συνδέονται (Cuomo, 2002, 1).Στην οικοφεμινιστική θεωρία εξετάζεται αυτή η συσχέτιση μεταξύ των διαφόρων εκφάνσεων της ανθρώπινης ύπαρξης και του φυσικού κόσμου (Cuomo, 2002, 10).Επισημαίνεται η ανάγκη να εξαλειφθεί η τάση πρόσληψης του κόσμου με δυαδικούς όρους, αλλά και η ανάγκη στροφής σε αξίες υποτιμημένες ή παρερμηνευμένες στην παραδοσιακή ηθική, όπως η συμπόνια, η φροντίδα ή η αγάπη. Στόχος της εργασίας είναι η εξέταση της σχέσης των προαναφερθεισών μορφών με την γη, της Κρέουσας με την Τροία, της Διδούς με την Καρχηδόνα και της Λαβινίας με το Λάτιο, αλλά και πώς συνδέονται με τον ομώνυμο πρωταγωνιστή του έπους και την αποστολή του. Παράλληλα θα μελετηθεί η θέση τους στο σύστημα αξιών του έπους, και πιο συγκεκριμένα όσον αφορά την pietas και τον furor.
description: The subject of this dissertation is the study of female figures in Virgil’s Aeneid through the lens of ecofeminism, specifically the characters of Creusa, Dido and Lavinia. The fundamental principles of ecofeminism revolve around the connection between feminine and nature, as well as the oppression and destruction they face from the androcentric forces that have shaped Western culture (Quartarone, 2002, 147). In ecofeminism, everything comprises of natural and conceptual relationships; human and ecological reality are interconnected (Cuomo, 2002, 1). Ecofeminist theory explores this interrelation between the various expressions of human existence and the natural world (Cuomo, 2002, 10). There is an emphasis on eliminating the tendency to perceive the world in binary terms and a need to turn to undervalued or misinterpreted values in traditional ethics, such as compassion, care, or love. The objective of the thesis is to examine the relationship between the forementioned female figures and the land—Creusa with Troy, Dido with Carthage, and Lavinia with Latium—and how they are connected to the epic's eponymous protagonist and his mission. Additionally, their position in the value system of the epic will be explored, particularly concerning pietas and furor.

description: This study explored how teachers provided opportunities for young adolescent students to be empowered as learners. Despite the crucial role that self-regulated learning plays in enhancing students’ achievement at school and beyond, few studies have created a practice-based pedagogy aimed at enabling students to rationalise their goals, to accept responsibility for their learning and to develop their capabilities as resourceful learners in social learning environments. The research was conducted as dual case studies within a primary school and a secondary school as transitionally connected settings in Queensland, Australia. The middle years of schooling, Years 5 to 9, have been identified as being a critical stage of development in young adolescents’ lives for effective lifelong learning. How schools and teachers can contribute to fostering these learning qualities was highlighted as a topic relevant to current Australian and international educational policy and debate. Rich qualitative data were collected through semi-structured interviews and classroom observations from eight teacher participants in the middle years of schooling. Thematic analysis methods were used in inductive intra-case and cross-case processes of generating codes, categories and themes. The findings were reported as interpretations that were intertwined with snapshots of data that represented the voices of the teacher participants. The data foregrounded teachers’ practices to identify that in striving to foster students’ effective learning they implemented pedagogical approaches aimed beyond the management of students’ behaviour for compliance and they sought to empower students as resourceful learners. As an original contribution to knowledge, the findings were synthesised to construct a practice-based pedagogical model for self-regulated learning. The study found that the teachers endeavoured to provide opportunities for the students to regulate their own learning through pedagogical approaches that connect the learning, facilitate the learning, diversify the learning, socialise the learning and reflect on teaching. Extending this model, the transition pedagogy framework for self-regulated learning presents key elements that attend to the distinctive needs of young adolescent students in the primary–secondary transition years of schooling. This study’s findings offer a proactive pedagogical approach to behaviour management within classroom environments that focuses on potentiating students’ self-regulation of their learning.
Engagement as Learning: A Comparison Study of TEACCH and LEAP Educational Models for Preschoolers with Autism Spectrum Disorders
Creators: name: Hopkins, Elise Suzanne

description: This study examined differences in child engagement between inclusive and self-contained classroom models for preschool-aged children with autism spectrum disorders (ASD). The two models examined within the study—TEACCH (Treatment and Education of Autistic and related Communication handicapped Children) and LEAP (Learning Experiences: An Alternative Program for Preschoolers and parents)—are highly-regarded classroom models for preschoolers with ASD. TEACCH classrooms are often highly structured, self-contained classrooms, whereas LEAP is a naturalistic and fully inclusive model. Past research that compared these models did not show differences with regards to child outcomes (Boyd et al., in press). This study examined differences in engagement across the two classroom types. According to Adamson and Bakeman (1984), the environment that maximizes joint engagement and minimizes time spent unengaged sets the stage for optimal learning. Videos of preschool students with autism in TEACCH and LEAP classrooms were coded for states of joint engagement and unengagement, and percentage of time spent in these states were compared. Results of this study showed that TEACCH and LEAP had similar levels for joint engagement, so complex learning opportunities were comparable between the two models. However, LEAP had significantly lower levels of unengagement than TEACCH did, meaning that children in LEAP classrooms are engaging in learning opportunities more often than children in TEACCH classrooms. The findings of this study support inclusive, naturalistic classroom settings for preschoolers with autism to maximize learning opportunities.
Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at $\sqrt{s}=7$ and $8~\mathrm{TeV}$

Subjects: Monte-Carlo

description: A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and $20~\mathrm{fb}^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and $8~\mathrm{TeV}$, respectively. The combination includes measurements in top-quark pair events that exploit both the semi-leptonic and hadronic decays of the top quark, and a measurement using events enriched in single top quark production via the electroweak $t$-channel. The combination yields $m_{\mathrm{t}} = 172.52 \pm 0.14~(\mathrm{stat}) \pm 0.30~(\mathrm{syst}) ~\mathrm{GeV}$, with a total uncertainty of $0.33~\mathrm{GeV}$.

description: Using a break junction technique, we find a clear signature for the formation of conducting hybrid junctions composed of a single organic molecule (benzene, naphthalene or anthracene) connected to chains of platinum atoms. The hybrid junctions exhibit metallic-like conductance (~0.1-1G0), which is rather insensitive to further elongation by additional atoms. At low bias voltage the hybrid junctions can be elongated significantly beyond the length of the bare atomic chains. Ab initio calculations reveal that benzene based hybrid junctions have a significant binding energy and high structural flexibility that may contribute to the survival of the hybrid junction during the elongation process. The fabrication of hybrid junctions opens the way for combining the different properties of atomic chains and organic molecules to realize a new class of atomic scale interfaces.

More generally, if the cover $f$ varies in an analytic family, is this true at least for some member of the family? Our main result gives a criterion for this to happen.

description: We scrutinize the real-frequency structure of the self-energy in the superconducting state of the attractive Hubbard model within the dynamical mean-field theory. Within the strong-coupling superconducting phase which has been understood in terms of the Bose-Einstein condensation in the literature, we find two qualitatively different regions crossing over each other. In one region close to zero temperature, the self-energy depends on the frequency only weakly at low energy. On the other hand, in the region close to the critical temperature, the self-energy shows a pole structure. The latter region becomes more dominant as the interaction becomes stronger. We reveal that the self-energy pole in the latter region is generated by a coupling to a hidden fermionic excitation. The hidden fermion persists in the normal state, where it yields a pseudogap. We compare these properties with those of the repulsive Hubbard model relevant for high-temperature cuprate superconductors, showing that hidden fermions are a key common ingredient in strongly correlated superconductivity.

description: Obesity and diabetes are the most prevalent metabolic diseases in the United States, afflicting over 60% of the adult population. The immune system contributes to obesity and insulin resistance, which are likely linked to over-nutrition. The adipocyte is more than a static lipid storage unit, and plays a crucial role as an endocrine organ, inducing the recruitment of macrophages to adipose tissue in obesity. Macrophages, specifically pro-inflammatory or M1-polarized, are the immune cells most commonly associated with perpetuating inflammation in adipose tissue through the secretion of inflammatory cytokines. The number of macrophages is increased significantly in obese adipose tissue; the damaged tissue, potentially trigged by hypoxia, may attract macrophages to the site, as M1 macrophages have been observed to form “crown-like structures” (CLS) around dead or dying adipocytes. We reported that GLUT1 is the primary rate-limiting glucose transporter on type I macrophages, thus we hypothesize that GLUT1 is essential in the activation of the pro-inflammatory response of macrophages. To test this hypothesis, quantitative polymerase chain reaction (qPCR) was used to determine the expression of specific genes associated with the pro-inflammatory M1 response in both GLUT1M+ and GLUT1M- bone marrow-derived macrophages (BMDMs) and epididymal white adipose tissue (eWAT) of lean and obese mice. eWAT of GLUT1M+ and GLUT1M- mice fed either a high-fat diet (HFD) or low-fat diet (LFD) was collected to examine the effects of the GLUT1 deletion on diet-induced obesity (DIO). Preliminary data, qPCR results and histologic analysis of CLS in adipose tissue suggest that although macrophage infiltration is occurring, polarization to the pro-inflammatory M1 phenotype is inhibited, resulting in an attenuated inflammatory response. Ultimately, findings from this study yield insight into the contribution of glucose metabolism to macrophage polarization and obesity.

description: We study a capacity theory based on a definition of Hajł asz-Besov functions. We prove several properties of this capacity in the general setting of a metric space equipped with a doubling measure. The main results of the paper are lower bound and upper bound estimates for the capacity in terms of a modified Netrusov-Hausdorff content. Important tools are $γ$-medians, for which we also prove a new version of a Poincaré type inequality.

description: Active Galactic Nuclei (AGN) with bright radio jets offer the opportunity to study the structure of and physical conditions in relativistic outflows. For such studies, multi-frequency polarimetric very long baseline interferometric (VLBI) observations are important as they directly probe particle densities, magnetic field geometries, and several other parameters. We present results from first-epoch data obtained by the Korean VLBI Network (KVN) within the frame of the Plasma Physics of Active Galactic Nuclei (PAGaN) project. We observed seven radio-bright nearby AGN at frequencies of 22, 43, 86, and 129 GHz in dual polarization mode. Our observations constrain apparent brightness temperatures of jet components and radio cores in our sample to $>10^{8.01}$ K and $>10^{9.86}$ K, respectively. Degrees of linear polarization $m_{L}$ are relatively low overall: less than 10%. This indicates suppression of polarization by strong turbulence in the jets. We found an exceptionally high degree of polarization in a jet component of BL Lac at 43 GHz, with $m_{L} \sim$ 40%. Assuming a transverse shock front propagating downstream along the jet, the shock front being almost parallel to the line of sight can explain the high degree of polarization.

Those Strange Moscow Ladies: Queer Identity in the Poetry of Tsvetaeva and Parnok
Creators: name: McCorkle, Karina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Marina Tsvetaeva and Sophia Parnok were both Russian poets living during the first half of the twentieth century. Tsvetaeva is considered one of the most prominent poets of the Silver Age, and is recognized for her innovative and complex style. Parnok is far less well-known, by Russians and scholars alike, and the process of re-establishing her as a figure in Russian literary history began just thirty years ago, with the work of scholars that will be discussed below. What connects these two women is the affair they conducted from 1914 to 1916, and the poetry they wrote chronicling it. This paper endeavors to examine the poetry of Tsvetaeva and Parnok in the context of that relationship, and also to consider how their poetry and thought on queerness evolved afterwards.

Subjects: subject: 130202 Curriculum and Pedagogy Theory and Development
subject: 130103 Higher Education

description: This study focuses on the development of a Design Framework for Higher Education Curriculum Ecosystem design. The study views the world as a digital ecosystem where the physical and the virtual are fully intertwined and function through integrated social and technical architecture working together in a seamless mesh that is persistent and pervasive. This digital ecosystem is an open, flexible, demand driven, self-organising, collaborative environment. It has enhanced individuals’ abilities to connect with other people, share ideas, work collaboratively and form communities. This has inevitably impacted on educational practice in Higher Education. The thesis draws together educational theories, curriculum designs, and concepts drawn from ecological psychology, cognitive apprenticeship, distributed cognition and activity theory, and extends them through the application of a Complexity Science lens. A Complexity Science perspective views the world as comprised of Complex Adaptive Systems. This study explores how authentic learning processes can be scaffolded within a Complex Adaptive System. The iterative development and refinement, through three iterations over six years, of a curriculum ecosystem for a Built Environment Degree Program is used as a case study for the development of a Higher Education curriculum ecosystem exemplar. A Design Framework for a Curriculum Ecosystem for Higher Education which has emerged through this process is presented.

description: We report first results from KVN and VERA Array (KaVA) VLBI observations obtained in the frame of our Plasma-physics of Active Galactic Nuclei (PAGaN) project. We observed eight selected AGN at 22 and 43 GHz in single polarization (LCP) between March 2014 and April 2015. Each source was observed for 6 to 8 hours per observing run to maximize the $uv$ coverage. We obtained a total of 15 deep high-resolution images permitting the identification of individual circular Gaussian jet components and three spectral index maps of BL Lac, 3C 111 and 3C 345 from simultaneous dual-frequency observations. The spectral index maps show trends in agreement with general expectations -- flat core and steep jets -- while the actual value of the spectral index for jets shows indications for a dependence on AGN type. We analyzed the kinematics of jet components of BL Lac and 3C 111, detecting superluminal proper motions with maximum apparent speeds of about $5c$. This constrains the lower limits of the intrinsic component velocities to $\sim0.98c$ and the upper limits of the angle between jet and line of sight to $\sim$20$°$. In agreement with global jet expansion, jet components show systematically larger diameters $d$ at larger core distances $r$, following the global relation $d\approx0.2r$, albeit within substantial scatter.

The Effect of Complexity versus the Effect of Naturalness on Phonological Learning
Creators: name: Prickett, Brandon
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Recently a “surfeit of the stimulus” has been noticed in languages; specifically speakers do not seem to be learning all of the phonological patterns that exist in their language (Becker et al. 2007, 2008, 2011). Using the Hayes and Wilson (2008) phonotactic learner software to create a list of phonological patterns that are in English words, Hayes and White (2013) found that phonological constraints that were “natural”—that is typologically common and phonetically logical—seemed to have been learned better by speakers. Recent research using artificial languages has suggested that complexity has a stronger effect on phonological learning than naturalness (see Moreton and Pater 2012b for a review of experiments of this nature).
The current study seeks to use Hayes and White’s methodology to test the effects of both naturalness and complexity on phonological learning. Subjects took part in an online experiment that presented an orthographic representation and an audio recording for each of the stimuli. Subjects were asked to numerically rate each of the words on how “good” they sounded in English and ratings of the experimental stimuli were compared with control group partners that did not break any constraints to determine how much of an effect each constraint had on the speakers’ judgments. The stronger a constraint’s effect was, the better learned it was assumed to be. Naturalness seemed to affect learning more than complexity—contradicting the findings of many recent studies on artificial language learning (see above citation) and suggesting that there could be significant differences in the processes that speakers use to learn real-world languages such as English and those used to learn artificial languages in a lab.
Relegitimization in Contemporary Russia: Putin's PR Project
Creators: name: Elutilo-Ayoola, Temitope
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: In this thesis, empirical methods will be employed and Russia will be used as a case
study in order to understand the theoretical basis for how a semi-authoritarian government can
restore and maintain legitimacy when its rule is under scrutiny. The research question that I just
presented is important because the concept of legitimacy can be used as a socio-political contract
that binds political and social systems. Understanding the case of Russia as a political
phenomenon will provide insight on legitimization techniques that can be employed when
positions of authority are under threat in order to restore the socio-political contract that grants
the right to rule. This study is significant because it contributes to ongoing discourse regarding
methods of legitimization and is relevant to current events occurring in Russia today. This study
is likely to appeal to scholars interested in understanding the mystique regarding Putin’s
consolidation of power. This study can also potentially interest those who participated in the
2011-2012 anti-Putin protest movement and increase their consciousness regarding the current
source of Putin’s support base in order to form a stronger oppositional front in the future.
Drawing from previous research on legitimacy, nationalist ideology, and popular support
for semi-authoritarian regimes, this thesis offers value-based legitimacy as an explanation for
Putin’s ability to overcome threats to his rule. In the following sections, I will first provide a
definition of terms that will be utilized throughout this study. Then, I will provide a brief
historical background on Putin’s first two presidential terms in order to provide perspective on
the unique nature of his third term. Next, an examination of previous literature that relate to this
study will be presented to provide the framework in which this study will be conducted. Then, I
will present a theory that aims to explain how Putin has been able to restore and maintain his
legitimacy in his third presidential term. Afterwards, strategies employed by Putin to enhance
his legitimacy will undergo a brief analysis in order to examine how they are rooted in nationalist
ideology and Russian traditionalism. Then, I will describe the methods employed in this study
and then presents the results of my empirical analysis. Finally, I will conclude with statements
on these results and comment on projections for future research in relation to this study.
