Near-horizon brane-scan revived

description: In 1987 two versions of the brane-scan of D-dimensional super p-branes were put forward. The first pinpointed those (p,D) slots consistent with kappa-symmetric Green-Schwarz type actions; the second generalized the "membrane at the end of the universe" idea to all those superconformal groups describing p-branes on the boundary of AdS_{p+2} x S^{D-p-2}. Although the second version predicted D3 and M5 branes in addition to those of the first, it came unstuck because the 1/2 BPS solitonic branes failed to exhibit the required symmetry enhancement in the near-horizon limit, except in the non-dilatonic cases (p=2,D=11), (p=3,D=10) and (p=5,D=11). Just recently, however, it has been argued that the fundamental D=10 heterotic string does indeed display a near-horizon enhancement to OSp(8|2) as predicted by the brane-scan, provided alpha' corrections are taken into account. If this logic could be extended to the other strings and branes, it would resolve this 21-year-old paradox and provide new AdS/CFT dualities, which we tabulate.

description: The electronic properties of junctions defined electrostatically on twisted bilayer graphene can be addressed theoretically using lattice models. Recent works have introduced minimal local orbital models to describe twisted bilayer graphene at the magic angle (MATBLG) with different degrees of approximation and accounting for fragile topology. In the present work we use a Green's function formalism to obtain the spectral and transport properties for MATBLG junctions based on these models. We introduce different symmetry breaking perturbations to simulate the effect of interactions and characterize the topology of the bulk bands by analyzing the corresponding Wilson loops. We then analyze the spectral properties for different types of edges and in the case of a domain wall in the sublattice symmetry breaking parameter. We further consider a three region junction where one could control independently the central and lateral regions doping level. In the limit where the central region is fixed at the charge neutrality point and the lateral ones are heavily doped, the spectral and the two terminal transport properties can be understood in terms of the hybridization of chiral states along the junctions. These properties are found to be extremely sensitive to the orientation of the junctions along the moiré lattice.

description: We measure rate asymmetries for the rare decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-, using a sample of 384 million BBbar events collected with the Babar detector at the PEP-II e+e- collider. We find no evidence for direct CP or lepton-flavor asymmetries. For dilepton masses below the J/psi resonance, we find evidence for unexpectedly large isospin asymmetries in both B->Kl+l- and B->K*l+l-, which differ respectively by 3.2 sigma and 2.7 sigma, including systematic uncertainties, from the Standard Model expectations.

Furthermore, the one-dimensional optimal system is derived while the Lie invariants are applied for the derivation of similarity transformations. We present different kinds of oscillating solutions.

description: We present the first calculation of the $x$-dependence of the isovector transversity generalized parton distributions (GPDs) for the proton within lattice QCD. We compute the matrix elements with non-local operators containing a Wilson line. The calculation implements the Breit symmetric frame. The proton momenta are chosen as $0.83,\,1.25,\,1.67$ GeV, and the values of the momentum transfer squared are $0.69,\,1.02$ GeV$^2$. These combinations include cases with zero and nonzero skewness. The calculation is performed using one ensemble of two degenerate-mass light, a strange and a charm quark of maximally twisted mass fermions with a clover term. The lattice results are renormalized non-perturbatively and finally matched to the light-cone GPDs using one-loop perturbation theory within the framework of large momentum effective theory. The final GPDs are given in the $\overline{\rm MS}$ scheme at a scale of 2 GeV. In addition to the individual GPDs, we form the combination of the transversity GPDs that is related to the transverse spin structure of the proton. Finally, we extract the lowest two moments of GPDs and draw a number of important qualitative conclusions.

description: We have investigated decorrelation of samples in Quantum Monte Carlo (QMC) ground-state energy calculations for large Li and H$_{2}$O nanoclusters. Binning data as a way of eliminating statistical correlations, as is the common practice, is found to become increasingly impractical as the system size grows. We demonstrate nevertheless that it is possible to perform accurate energy calculations - without decorrelating samples - by exploiting the scaling of the integrated autocorrelation time $τ$ as a function of the number of electrons in the system.

Emergent Gravity from Noncommutative Gauge Theory

description: We show that the matrix-model action for noncommutative U(n) gauge theory actually describes SU(n) gauge theory coupled to gravity. This is elaborated in the 4-dimensional case. The SU(n) gauge fields as well as additional scalar fields couple to an effective metric G_{ab}, which is determined by a dynamical Poisson structure. The emergent gravity is intimately related to noncommutativity, encoding those degrees of freedom which are usually interpreted as U(1) gauge fields. This leads to a class of metrics which contains the physical degrees of freedom of gravitational waves, and allows to recover e.g. the Newtonian limit with arbitrary mass distribution. It also suggests a consistent picture of UV/IR mixing in terms of an induced gravity action. This should provide a suitable framework for quantizing gravity.

Aspects of tapered optical fibre polarizers
Creators: name: Lefrançois, Marcel
Publisher: name: University of British Columbia
Year: 2010

description: This thesis proves that it is possible in principle to make in line optical fibre polarizers from tapered optical fibres surrounded by a quartz cladding. The theory of light propagation and polarization in fibres was reviewed as background information and several fabrication processes were evaluated and tried experimentally. The best results are obtained by heating a quartz tube in an oxy-propane flame, so that it collapses onto the fibre. Unfortunately, due to residues remaining between fibre and quartz tube, and due to large differences in melting points the results are quite irreproducible, and routine fabrication of polarizers with predictable properties is not yet feasible by the methods described in this thesis.

description: We analyse the breakdown of supersymmetry in an ISS model in the presence of gravity, under the requirement that the cosmological constant vanishes dynamically. The gravitational backreaction is calculated in the metastable minimum and, in conjuction with the condition V=0, this is shown to generate non-zero F-terms for the squarks. Once the squarks are coupled to the messenger sector, a gauge mediation scheme is realised and it leads to a distinctive soft spectrum, with a two order of magnitude split between the gaugino and the soft scalar masses.

Constraining Radiatively Inefficient Accretion Flows with Polarization

description: The low-luminosity black hole Sgr A* provides a testbed for models of Radiatively Inefficient Accretion Flows (RIAFs). Recent sub-millimeter linear polarization measurements of Sgr A* have provided evidence that the electrons in the accretion flow are relativistic over a large range of radii. Here, we show that these high temperatures result in elliptical plasma normal modes. Thus, polarized millimeter and sub-millimeter radiation emitted within RIAFs will undergo generalized Faraday rotation, a cyclic conversion between linear and circular polarization. This effect will not depolarize the radiation even if the rotation measure is extremely high. Rather, the beam will take on the linear and circular polarization properties of the plasma normal modes. As a result, polarization measurements of Sgr A* in this frequency regime will constrain the temperature, density and magnetic profiles of RIAF models.

description: We discuss the signals at the Large Hadron Collider (LHC) for scenarios with non-universal gaugino masses in supersymmetric (SUSY) theories. We perform a multichannel analysis, and consider the ratios of event rates in different channels such as $jets + {E}_T/ $, $same$ - and $opposite$-$sign dileptons$ $+jets+ {E}_T/ $, as well as $single-lepton$ and $trilepton$ final states together with $jets + {E}_T/ $ . Low-energy SUSY spectra corresponding to high-scale gaugino non-universality arising from different breaking schemes of SU(5) as well as SO(10) Grand Unified (GUT) SUSY models are considered, with both degenerate low-energy sfermion masses and those arising from a supergravity scenario. We present the numerical predictions over a wide range of the parameter space using the event generator {\tt Pythia}, specifying the event selection criteria and pointing out regions where signals are likely to be beset with backgrounds. Certain broad features emerge from the study, which may be useful in identifying the signatures of different GUT breaking schemes and distinguishing them from a situation with a universal gaugino mass at high scale. The absolute values of the predicted event rates for different scenarios are presented together with the various event ratios, so that these can also be used whenever necessary.

description: Climate change may contribute to the spatio-temporal occurrence of disasters. Long-term studies of either homogeneous or heterogeneous responses of historical disasters to climate change are, however, limited by the quality and quantity of the available proxy data. Here we reconstruct spatio-temporal patterns of five types of disasters in China during the period AD 1368–1911. Our analyses of these time series reveal that warmer temperatures decreased the occurrence of disasters in the monsoon-affected parts of central-east China, but it increased the frequency and intensity of disasters along the boundary of arid and humid conditions in parts of southwest and northeast China, likely driven by the interplay among monsoon, westerlies, polar vortex and variation of temperature. Moreover, we show that drought and flood events had cascading effects on the occurrences of locust outbreaks, famine and human epidemics. Our findings suggest that climate can contribute to the spatio-temporal occurrence of disasters, and therefore may contribute to an improvement of China's regional to national risk management of future climate and environmental change.
Affirmative or Threatening: The Role of Romantic Partner’s Affect in Leader Identity Management
Creators: name: Zhang, Jingyu
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The self-perception of an individual in a leadership role, referred to as leader identity, is
central to a leader’s self-understanding and effectiveness. Building on previous work suggesting
that leaders construct leader identity through interactions, I extend the current focus to
interactions between leaders and their romantic partners. Drawing from the cross-domain
leadership development model and the emotion as social information model, I propose a
theoretical framework that illustrates how a partner’s positive and negative affect toward one’s
leadership role may influence leader identity and leadership behaviors through both affective and
inferential pathways via leader affect and leadership self-efficacy. Moreover, I suggest that a
leader’s self-verification motive serves as a critical contingency that shapes how they notice and
interpret identity cues. To test the proposed model, I conducted a multi-source, time-lagged study
of 168 leader–partner dyads. The findings demonstrate that partner positive affect toward one’s
leadership role had indirect effects on leader identity and task-, person-, and change-oriented
leadership behaviors via leadership self-efficacy. Moreover, partner negative affect also had
negative indirect effects on leader identity and leader behaviors via leader negative affect.
Additionally, the leader’s self-verification motive was a significant moderator that influenced
these relationships. This research contributes to the leader identity literature by identifying the
role of partner affect toward one’s leadership role and the mechanisms that link it to leader
identity salience and enactment.

description: We present interferometric and single-dish mid-infrared observations of a sample of massive young stellar objects (BN-type objects), using VLTI-MIDI (10 micron) and Subaru-COMICS (24.5 micron). We discuss the regions S140, Mon R2, M8E-IR, and W33A. The observations probe the inner regions of the dusty envelope at scales of 50 milli arcsecond and 0.6 arcsec (100-1000 AU), respectively. Simultaneous model fits to spectral energy distributions and spatial data are achieved using self-consistent spherical envelope modelling. We conclude that those MYSO envelopes that are best described by a spherical geometry, the commensurate density distribution is a powerlaw with index -1.0. Such a powerlaw is predicted if the envelope is supported by turbulence on the 100-1000AU scales probed with MIDI and COMICS, but the role of rotation at these spatial scales need testing.

description: From Yao Lin's critique of Chinese market intellectuals', to Breuer & Johnston's description of the Sino-US relations insecurity spiral, to the death knells of political ideologues, Incels, mass shooters, and culture wars online in fringe spaces, even to the rhetoric of academia, in simplistic hypothesis testing, failing to induce, failing to be creative, the digital era is a "schizoid function" which validates users' ego to the extent of whatever stake they put into myriad platforms. Users narratives’ always grow dense, and occupy a hypercharged position in the conduit of American politics; where potential capital is the alt-Right or fringe, who has the motivation to evolve the regnant memes of the contemporary, post-modern, liberal world. The difference between Fringe and Mainstream? Breuer & Johnston ask, "could the so called US-dominated liberal world order be in decline?" Fringe, alt-Right, existential, and Traditionalist ideologues inherently believe yes, mainstream liberalism, no. It is an inverted space: as AH Stuart proposes, users more likely to engage in such binary discourse are nihilistic, egoistical, and motivate massive amounts of potential capital, implying van Ginneken's 2013 conjecture: digital spaces are apogenetic, and cultures, like the US, in endemic decline always irrationally evolve regnant dogma. The digital space is inherently "degenerate", to borrow the alt-Right's own logic. Ergo, Leviathan is too patrician to inherit the vulgar dialect of digital era statecraft, because statecraft inherits the fringe actors of the "schizoid" space (Harris 1995); where each actor intrinsically must offload their fears and distrust of the world itself (ie. Kruger 2021) and justify it under the iconoclasm of politics.

We find that different combinations of the DM anisotropies lead to a wide variety of thermodynamic behavior, which are quite distinct from those of most other perturbations. We argue that the sudden upturn seen experimentally in the susceptibility of the material ZnCu3(OH)6Cl2 can be understood in terms of Dzyaloshinsky-Moriya anisotropies with D_p>|D_z|. We also show that the measured specific heat of the material puts further constraints on the allowed DM parameters.

A photometric and morphological study of compact groups of galaxies and their environments
Creators: name: Kindl, Enrico
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines properties of galaxies in and around compact groups. Astrometry, photometry and morphological classifications are derived from CCD images for all 463 galaxies in Hickson's sample of 100 compact groups. Some minor revisions to the membership of the original catalog are made. At high galactic latitude (b > 30°), the catalog is estimated to be 90% complete for groups with total B[formula omitted] magnitude 13.0 or less. 49% of all the catalogued galaxies, and 48% of first-ranked galaxies are spiral. No significant difference is found between the distribution of morphological types of first-ranked galaxies and all group galaxies. Morphological concordance occurs among galaxies within a group: more galaxies are the same type (spiral or nonspiral), than would be expected by chance. Galaxy morphological type correlates with group optical luminosity and, more strongly, with velocity dispersion, but not with galaxy space density. These results imply that the morphological types of galaxies in compact groups are strongly influenced by the environment, and that this influence occurs mostly at the time of galaxy formation. Fields surrounding 97 compact groups with known redshifts were examined on the Palomar Observatory Sky Survey prints. 3889 galaxies were identified within 1.125h⁻¹ Mpc of the centre of each group. Coordinates, magnitudes, diameters, and Hubble types are derived for these galaxies. 78% of the groups show no significant excess of field galaxies within 0.5h⁻¹ Mpc. This indicates that most compact groups are truly isolated. 59% of these field galaxies were classified as spiral, a higher fraction that for the group galaxies. This difference is more pronounced for groups which do show a significant field galaxy excess. These results indicate that most groups are dense dynamical entities. Monte-Carlo calculations indicate that 35% of galaxy quintets are predicted to contain a single discordant redshift due to the chance alignment of an unrelated field galaxy. This is in agreement with the observed number of four discordant quintets in 10. These results are consistent with the cosmological interpretation of galaxy redshifts.

description: The Aharonov-Bohm (AB) effect is a purely quantum mechanical effect. The original (classified as Type-I) AB-phase shift exists in experimental conditions where the electromagnetic fields and forces are zero. It is the absence of forces that makes the AB-effect entirely quantum mechanical. Although the AB-phase shift has been demonstrated unambiguously, the absence of forces in Type-I AB-effects has never been shown. Here, we report the observation of the absence of time delays associated with forces of the magnitude needed to explain the AB-phase shift for a macroscopic system.

description: We propose a new formalism for quantum field theory which is neither based on functional integrals, nor on Feynman graphs, but on marked trees. This formalism is constructive, i.e. it computes correlation functions through convergent rather than divergent expansions. It applies both to Fermionic and Bosonic theories. It is compatible with the renormalization group, and it allows to define non-perturbatively {\it differential} renormalization group equations. It accommodates any general stable polynomial Lagrangian. It can equally well treat noncommutative models or matrix models such as the Grosse-Wulkenhaar model. Perhaps most importantly it removes the space-time background from its central place in QFT, paving the way for a nonperturbative definition of field theory in noninteger dimension.

description: One of the most notorious non-Fermi liquid properties of both archetypal heavy-fermion systems [1-4] and the high-Tc copper oxide superconductors [5] is an electrical resistivity that evolves linearly with temperature, T. In the heavy-fermion superconductor CeCoIn5 [5], this linear behaviour was one of the first indications of the presence of a zero-temperature instability, or quantum critical point. Here, we report the observation of a unique control parameter of T-linear scattering in CeCoIn5, found through systematic chemical substitutions of both magnetic and non-magnetic rare-earth, R, ions into the Ce sub-lattice. We find that the evolution of inelastic scattering in Ce1-xRxCoIn5 is strongly dependent on the f-electron configuration of the R ion, whereas two other key properties -- Cooper-pair breaking and Kondo-lattice coherence -- are not. Thus, T-linear resistivity in CeCoIn5 is intimately related to the nature of incoherent scattering centers in the Kondo lattice, which provides insight into the anomalous scattering rate synonymous with quantum criticality [7].

Schwinger Mechanism for Gluon Pair Production in the Presence of Arbitrary Time Dependent Chromo-Electric Field

description: We study Schwinger mechanism for gluon pair production in the presence of arbitrary time-dependent chromo-electric background field $E^a(t)$ with arbitrary color index $a$=1,2,...8 in SU(3) by directly evaluating the path integral. We obtain an exact expression for the probability of non-perturbative gluon pair production per unit time per unit volume and per unit transverse momentum $\frac{dW}{d^4x d^2p_T}$ from arbitrary $E^a(t)$. We show that the tadpole (or single gluon) effective action does not contribute to the non-perturbative gluon pair production rate $\frac{dW}{d^4x d^2p_T}$. We find that the exact result for non-perturbative gluon pair production is independent of all the time derivatives $\frac{d^nE^a(t)}{dt^n}$ where $n=1,2,....\infty$ and has the same functional dependence on two casimir invariants $[E^a(t)E^a(t)]$ and $[d_{abc}E^a(t)E^b(t)E^c(t)]^2$ as the constant chromo-electric field $E^a$ result with the replacement: $E^a \to E^a(t)$. This result may be relevant to study the production of a non-perturbative quark-gluon plasma at RHIC and LHC.

description: The Simons Observatory (SO) Large Aperture Telescope Receiver (LATR) will be coupled to the Large Aperture Telescope located at an elevation of 5,200 m on Cerro Toco in Chile. The resulting instrument will produce arcminute-resolution millimeter-wave maps of half the sky with unprecedented precision. The LATR is the largest cryogenic millimeter-wave camera built to date with a diameter of 2.4 m and a length of 2.6 m. It cools 1200 kg of material to 4 K and 200 kg to 100 mk, the operating temperature of the bolometric detectors with bands centered around 27, 39, 93, 145, 225, and 280 GHz. Ultimately, the LATR will accommodate 13 40 cm diameter optics tubes, each with three detector wafers and a total of 62,000 detectors. The LATR design must simultaneously maintain the optical alignment of the system, control stray light, provide cryogenic isolation, limit thermal gradients, and minimize the time to cool the system from room temperature to 100 mK. The interplay between these competing factors poses unique challenges. We discuss the trade studies involved with the design, the final optimization, the construction, and ultimate performance of the system.

description: In recent years, with the increasing popularity of "Smart Technology", the number of Internet of Things (IoT) devices and systems have surged significantly. Various IoT services and functionalities are based on the analytics of IoT streaming data. However, IoT data analytics faces concept drift challenges due to the dynamic nature of IoT systems and the ever-changing patterns of IoT data streams. In this article, we propose an adaptive IoT streaming data analytics framework for anomaly detection use cases based on optimized LightGBM and concept drift adaptation. A novel drift adaptation method named Optimized Adaptive and Sliding Windowing (OASW) is proposed to adapt to the pattern changes of online IoT data streams. Experiments on two public datasets show the high accuracy and efficiency of our proposed adaptive LightGBM model compared against other state-of-the-art approaches. The proposed adaptive LightGBM model can perform continuous learning and drift adaptation on IoT data streams without human intervention.

description: Monitoring muraw zasobnych w metale ciężkie rozpoczął się w Polsce dopiero w roku 2013, a więc siedem lat po wprowadzeniu regularnego monitoringu siedlisk przyrodniczych dla potrzeb Art. 17 Dyrektywy 92/43/EWG. Dlatego w chwili obecnej dostępne na stronach Głównego Inspektoratu Ochrony Środowiska dostępne są tylko wyniki z okresów badawczych 2013-2014 oraz 2015-2018, przy czym należy zauważyć że metodyka monitoringu zostałaopublikowana dopiero w roku 2015, badania w okresie wcześniejszym były więc prowadzone na podstawie wstępnej listy wskaźników.W obu okresach w badaniach monitoringowych ujęto 16 stanowisk, w tym 7 na hałdach pozostałych po górnictwie ołowiu i cynku w regionie śląsko-małopolskim; 3 na hałdachpolimetalicznych na przedpolu Rudaw Janowickich oraz 6 transektów na dwóch stanowiskach pozostałości po górnictwie arsenu w Górach Złotych.Najpoważniejsze stwierdzone zagrożenia to sukcesja (Ryc. 1, 2), działalność górnicza (w tym rozbiórka hałd – Ryc. 3)) oraz zarzucenie pasterstwa. Na wielu stanowiskach odnotowano też występowanie szeregu gatunków inwazyjnych roślin naczyniowych. Łączna ocena stanusiedliska w kraju jest więc zła, ze względu na ponad 50% stanowisk ocenionych na U2.

description: Using the largest cosmological reionization simulation to-date (~24 billion particles), we use the genus curve to quantify the topology of neutral hydrogen distribution on scales > 1 Mpc as it evolves during cosmological reionization. We find that the reionization process proceeds primarily in an inside-out fashion, where higher density regions become ionized earlier than lower density regions. There are four distinct topological phases: (1) Pre-reionization at z ~ 15, when the genus curve is consistent with a Gaussian density distribution. (2) Pre-overlap at 10 < z < 15, during which the number of HII bubbles increases gradually with time, until percolation of HII bubbles starts to take effect, characterized by a very flat genus curve at high volume fractions. (3) Overlap at 8 < z < 10, when large HII bubbles rapidly merge, manifested by a precipitous drop in the amplitude of the genus curve. (4) Post-overlap at 6 < z < 8, when HII bubbles have mostly overlapped and the genus curve is consistent with a diminishing number of isolated neutral islands. After the end of reionization (z < 6), the genus of neutral hydrogen is consistent with Gaussian random phase, in agreement with observations.

Greek in Early Hellenistic Magna Graecia: Dialect Contact and Change in South Italy
Creators: name: Tagliapietra, Livia
Publisher: name: Apollo - University of Cambridge Repository
Year: 2018
Subjects: Ancient Greek dialects, Ancient Greek linguistics, Historical sociolinguistics, Magna Graecia, Ancient South Italy, Greek colonies of South Italy

description: This doctoral thesis investigates dialect contact, identity and change in the ancient Greek colonies of Magna Graecia in the fourth and third centuries BC, as evidenced in the surviving epigraphic sources. South Italy is an area of the ancient Greek-speaking world in which a comprehensive investigation of the linguistic evidence has not previously been attempted. By considering linguistic questions within their broader socio-historical environment, I propose a radical redrawing of the dialect map of this area. I first present the historical context, the linguistic evidence and the methodological framework of my research in the introduction. In the first chapter I reject previous hypotheses about dialect contact in South Italy around 300 BC on the basis of both historical and linguistic arguments. I then propose a new and empirically better supported explanation for the development of the ‘severior’ long-vowel system in the dialect of the southern city of Locri, which previous studies have generally attributed to influence from the dialect of the important northern city of Taras and taken as evidence for Taras’ linguistic influence over the rest of Magna Graecia, and possibly also for the existence of a local Doric koina (i.e. a common dialect). In the second chapter I offer a new analysis of the inscriptional record from Locri and show that, in the absence of compelling evidence for influence from the dialect of Taras, a high level of prestige remained attributed to the traditional local dialect until at least the mid-third century. At the same time, the southern colonies in general, including Locri, can be shown to have been exposed to the koine before the northern ones, such as Taras, as a result of frequent contact with the Greeks of near Sicily in the fourth and early third centuries. In the third chapter I complete my investigation by assessing the use of dialectal features in literary texts produced in South Italy around the same period (both metrical inscriptions and literary works transmitted in manuscripts). The evidence of these texts, combined with that of documentary inscriptions, provides a deeper insight into matters of dialect identity and prestige in this area. After summarising the results of my research, I conclude my investigation with a brief discussion of the socio-historical reasons why a Doric koina did not develop in South Italy as in other areas.

description: Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs. Different mappings are established between various models of spiders and simple exclusion processes. For spiders with simple gait and varying number of legs we compute the diffusion coefficient; when the hopping is biased we also compute their velocity.

Homer in the Perfect Tense: The Posthomerica of Quintus Smyrnaeus and the Poetics of Impersonation

description: The thesis has been written as part of the AHRC collaborative research project Greek Epic of the Roman Empire: A Cultural History. This project seeks to give the first cultural-historical analysis of the large, underexploited corpus of Greek epic poetry composed in the transformative period between the 1st and the 6th centuries C.E. The thesis focuses on questions of literary identity in one of the most challenging texts from this corpus, the Posthomerica by Quintus of Smyrna (c. 3rd century C.E.). My central contention is that Quintus’ mimicry of Homer represents a radically new formative poetics, suggesting a cultural movement towards mimesis, necromancy and close encounters with the past. After a detailed study of what I term the reanimating culture of imperial Greece (chapter 1), and a comprehensive reanalysis of the compositional techniques of the text (chapter 2), I identify a number of tropes of poetic identity from different ancient literary modes: programmatic proems (chapter 3), memory (4), filiation (5) and temporality (6). I show how Quintus co-opts these themes for his new poetics, to turn the symbolic toolkit of contrast imitation into a defence of writing inter-Homeric epic. This analysis insists on rethinking the nature of the relationship between the poetry of this era and that of previous aesthetic traditions: particularly, I argue against a view of the Posthomerica as Alexandrian, and see it instead pushing back against the Callimachus school of small, new poetry. Ultimately, the thesis aims to show how the Posthomerica could be pivotal for unpinning current critical assumptions about imperial Greek poetry; revealing a palpable shift in tone in the construct of the literary self.

The informational needs of historians researching women : an archival user study
Creators: name: Beattie, Diane Lynn
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the informational needs of historians researching women as a subject in archives. The research methodology employed combines two types of user studies, the questionnaire and the reference analysis, in order to determine both the use and usefulness of archival materials and finding aids for historians researching women. This study begins with an overview of the literature on user studies. The thesis then outlines both the kinds of materials and the information historians researching women require. Finally, this study looks at the way historians researching women locate relevant materials and concomitantly the effectiveness of current descriptive policies and practices in dealing with the needs of this research group. This thesis concludes by suggesting a number of ways in which archivists can respond to the informational needs of historians researching women in archives. Firstly, a considerable amount of documentation relevant to the study of women remains to be acquired by archival repositories. While archives should continue to acquire textual materials, more emphasis needs to be placed upon the acquisition of non-textual materials since these materials are also very useful to historians researching women in archives. Secondly, archivists must focus more attention on the informational value of their holdings since the majority of historians researching women are interested in the information the records contain about people, events or subject area and not the description of institutional life contained in records. Thirdly this study demonstrates the need for more subject oriented finding aids. Archivists can improve subject access to their holdings through the preparation of thematic guides, by the creation of more analytical inventory descriptions and by indexing or cataloguing women's records.
