#LoveLibraries - Hashtags and folksonomies in public library Instagram accounts
Creators: name: Hartley, Chloe
Publisher: name: Reflective Professional
Year: 2023

description: This study explores the impact on user engagement that hashtags and folksonomies can have in the context of the Instagram app, specifically in a post COVID-19 context, where services like libraries were stripped of their physical provisions and may have increased their use of social media. To achieve this, secondary data from pre-existing Instagram accounts was gathered using a coding schema, for the means of investigating current trends in hashtag use. A selection of social tags that were deemed popular in correlation with boosting engagement were examined and then adapted to create tailored hashtags to be posted by the collaborative public library service, Orkney Library and Archives. This was implemented through an action research approach, with pre-existing Instagram accounts acting as the diagnostic phase, with the application of the customised tags by Orkney Library enacting the therapeutic stage. The research was designed to be unobtrusive, in keeping with themes central to passive netnography. The study found there to be a positive correlation between the use of emotive hashtags and user comments, with a higher volume of comments found on posts containing this type of hashtags, and respondents more likely to leave text-rich qualitative responses as opposed to only emojis. Other hashtag types which were found to have value in driving engagement were geographical and rallying types. Due to time constraints, only one cycle of action research approach was able to be conducted, and it is recommended that further research on this topic is continued to gain a more comprehensive understanding of the impact social tags can have on engagement.

description: The main purpose of this survey was to identify non-retirement migrants in each of the study areas so that these individuals could be contacted again at a later date and more detailed questions asked concerning their post-migrational experiences. As the sample was taken from the whole population of each area, the opportunity to gather some basic information concerning the age, sex, marital status, employment status, birthplace, completion of full-time education, length of residence at current address and size of the household was taken. Such an approach has not only proved successful in identifying non-retirement migrants but has also enabled a comparison of the various sub-groups of the population to see for example whether significant differences in the educational attainment and employment characteristics of migrants and non-migrants exist.

description: Using acoustic methods we have measured nonlinear AC conductance in 2D arrays of Ge-in-Si quantum dots. The combination of experimental results and modeling of AC conductance of a dense lattice of localized states leads us to the conclusion that the main mechanism of AC conduction in hopping systems with large localization length is due to the charge transfer within large clusters, while the main mechanism behind its non-Ohmic behavior is charge heating by absorbed power.

The Impact of the COVID-19 Pandemic on Readers’ Advisory Services in Southern Ontario Public Libraries
Creators: name: McLean, Suzanne
Publisher: name: Reflective Professional
Year: 2023

description: The aim of this research was to investigate the potential effects of the COVID-19 pandemic on the readers’ advisory services (RA) provided by southern Ontario public libraries. Its objectives were to determine whether there have been changes in patron demand for readers’ advisory and whether libraries have responded to pandemic restrictions by changing their readers’ advisory offerings. A final objective was to develop recommendations for public libraries wanting to improve their RA services. A review of the literature found that there are many studies examining the history of readers’ advisory, and the way RA is practised in North American public libraries. However, there has not yet been much research published exploring the ways in which the pandemic has affected readers’ advisory services in public libraries, nor has there been a lot of research examining the ways in which public libraries have adapted these services to better serve the public during pandemic restrictions. This research was intended to address this gap in the literature. A mixed-methods approach was chosen for this research as the best course to acquire both quantitative and qualitative data. First, a questionnaire was distributed to southern Ontario public library staff. The questionnaire explored various types of readers’ advisory services and asked respondents about their library’s responses to pandemic restrictions. Next, follow-up interviews were conducted with select questionnaire respondents to obtain more detailed and nuanced information regarding readers’ advisory services at their libraries during the pandemic. It was found that most libraries had found some changes in demand for RA services during the pandemic. More patrons were asking for books to be chosen for them when they were unable to visit the library during lockdowns or restrictions. Most libraries also implemented some type of new RA service during the pandemic. Recommendations were made for public libraries to continue to adapt their RA services to better serve their patrons. These recommendations included better RA training for staff, fostering a culture of “booktalking” and advertising RA services more effectively.

description: Damping of longitudinal coherent bunched-beam oscillations is needed in SIS18 and SIS100 to stabilize the beam, prevent emittance growth and keep beam loss low during acceleration. In last year’s work several approaches of digital filters for beam-phase control have been examined. An FIR (finite impulse response) filter with 3 taps, cf. [1], has been successfully used at GSI in several machine experiments for a beam-phase control system and a longitudinal feedback system. In this report an alternative FIR filter approach based on derivative estimation leads to better results as it damps dipole oscillations within one oscillation period whereas the former filter approach unveils its full potential only after one oscillation period.

description: The application of the non conventional imaging technique LOFI (Laser Optical Feedback Imaging) to coherent microscopy is presented. This simple and efficient technique using frequency-shifted optical feedback needs the sample to be scanned in order to obtain an image. The effects on magnitude and phase signals such as vignetting and field curvature occasioned by the scanning with galvanometric mirrors are discussed. A simple monitoring method based on phase images is proposed to find the optimal position of the scanner. Finally, some experimental results illustrating this technique are presented.

description: Bibliography: p. 118-121.
description: The characteristics of an in situ combustion process carried out on a light crude oil are different from those normally depicted by heavy oils or tar sands. The kinetics of such a process, however, are extremely specific to the oil investigated. Combustion tube tests are normally performed to evaluate the air or oxygen and fuel requirement parameters. The product gas compositions from combustion tube tests are also useful for evaluating field performance, as it is possible to evaluate the relationship between gas composition and the temperature profiles in the laboratory experiments. In field projects there is generally little information on temperature profiles, but the gas composition can be monitored. This study is based on the data (produced gas compositions, peak temperatures and post burn residues) provided by laboratory experiments on re-constituted cores from the Countess Band D pools. Through the apparent atomic hydrogen to carbon ratio, it was found that the overall kinetics of the combustion process for Countess B oil undergo a transition over a temperature range of 260°c to 270°c, and that a negative temperature coefficient region exists between 310°c and 350°c. The virtual absence of residual coke suggested that the hydrocarbon fuel is an asphaltenes type fraction.

description: This volume contains the proceedings of the Eighth Workshop on Fixed Points in Computer Science which took place on 24 March 2012 in Tallinn, Estonia as an ETAPS-affiliated workshop. Past workshops have been held in Brno (1998, MFCS/CSL workshop), Paris (2000, LC workshop), Florence (2001, PLI workshop), Copenhagen (2002, LICS (FLoC) workshop), Warsaw (2003, ETAPS workshop), Coimbra (2009, CSL workshop), and Brno (2010, MFCS-CSL workshop). Fixed points play a fundamental role in several areas of computer science and logic by justifying induction and recursive definitions. The construction and properties of fixed points have been investigated in many different frameworks such as: design and implementation of programming languages, program logics, and databases. The aim of this workshop is to provide a forum for researchers to present their results to those members of the computer science and logic communities who study or apply the theory of fixed points.

Force chains and contact network topology in packings of elongated particles

Year: 2011
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: By means of contact dynamic simulations, we investigate the contact network topology and force chains in two-dimensional packings of elongated particles modeled by rounded-cap rectangles. The morphology of large packings of elongated particles in quasistatic equilibrium is complex due to the combined effects of local nematic ordering of the particles and orientations of contacts between particles. We show that particle elongation affects force distributions and force/fabric anisotropy via various local structures allowed by steric exclusions and the requirement of force balance. As a result, the force distributions become increasingly broader as particles become more elongated. Interestingly, the weak force network transforms from a passive stabilizing agent with respect to strong force chains to an active force-transmitting network for the whole system. The strongest force chains are carried by side/side contacts oriented along the principal stress direction.

Roche Accretion of stars close to massive black holes
Creators: name: Dai, Lixin

Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: In this paper we consider Roche accretion in an Extreme Mass-Ratio Inspiral (EMRI) binary system formed by a star orbiting a massive black hole. The ultimate goal is to detect the mass and spin of the black hole and provide a test of general relativity in the strong-field regime from the resultant quasi-periodic signals. Before accretion starts, the stellar orbit is presumed to be circular and equatorial, and shrinks due to gravitational radiation. New fitting formulae are presented for the inspiral time and the radiation-reaction torque in the relativistic regime. If the inspiralling star fills its Roche lobe outside the Innermost Stable Circular Orbit (ISCO) of the hole, gas will flow through the inner Lagrange point (L1) to the hole. We give new relativistic interpolation formulae for the volume enclosed by the Roche lobe. If this mass-transfer happens on a time scale faster than the thermal time scale but slower than the dynamical time scale, the star will evolve adiabatically, and, in most cases, will recede from the hole while filling its Roche lobe. We calculate how the stellar orbital period and mass-transfer rate will change through the "Roche evolution" for various types of stars in the relativistic regime. We envisage that the mass stream eventually hits the accretion disc, where it forms a hot spot orbiting the hole and may ultimately modulate the luminosity with the stellar orbital frequency. The observability of such a modulation is discussed along with a possible interpretation of an intermittent 1 hour period in the X-ray emission of RE J1034+396.

Follow-Up Survey of Journey to Work and Residential Location Patterns of Office Workers in Decentralised Offices, 1976
Creators: name: Daniels, P. W.
Publisher: name: UK Data Service
Year: 1983

description: This is a follow-up to an earlier (1969) survey, which is not held at the Archive.
 The purpose of this study was to obtain journey to work and residential location information from individual office workers with a view to exploring four hypotheses:
 1. that office workers employed in decentralized offices at the time of the earlier survey have retained broadly similar journey to work and residential location patterns;
 2. that replacement staff and new recruits have not changed to any significant degree the journey to work and residential location patters of decentralized office workers;
 3. that the detailed location characteristics of the 1969 and 1975 sample offices, particularly with respect to accessibility of public transport, affects the balance between public and private transport trips for the journey to work to decentralized offices;
 4. that decentralization had added to pressure with the housing market of the receiving location.
 The participants were (a) employees in decentralized offices which had participated in an earlier study in 1969 and (b) employees in decentralized offices in Watford, Swindon, Liverpool, Reading and Southampton (some of the establishments participating for the first time).

description: FS Tau B is one of the few T Tauri stars that possess a jet and a counterjet as well as an optically-visible cavity wall. We obtained images and spectra of its jet-cavity system in the near-infrared H and K bands using Subaru/IRCS and detected the jet and the counterjet in the [Fe II] 1.644 μm line for the first time. Within the inner 2" the blueshifted jet is brighter, whereas beyond ~ 5" the redshifted counterjet dominates the [Fe II] emission. The innermost blueshifted knot is spectrally resolved to have a large line width of ~ 110 km/s, while the innermost redshifted knot appears spectrally unresolved. The velocity ratio of the jet to the counterjet is ~ 1.34, which suggests that FS Tau B is driving an asymmetric jet, similar to those found in several T Tauri Stars. Combining with optical observations in the literature, we showed that the blueshifted jet has lower density and higher excitation than the redshifted counterjet. We suggest that the asymmetry in brightness and velocity is the manifestation of a bipolar outflow driving at different mass-loss rates, while maintaining balance of linear momentum. A full explanation to the asymmetry in the FS Tau B system awaits detail modeling and further investigation of the kinematic structure of the wind-associated cavity walls.

Different from the standard mean-field, in the stochastic approach, initial state fluctuations, are incorporated. In weak coupling, the approach perfectly reproduces the exact quantal dynamics. On the other hand, for increasing coupling strength, above the symmetry breaking threshold, the approach provides description of gross properties (i.e. time averaged behavior) of the exact quantal evolution.

description: We studied the interlayer coupling and decoupling of bilayer graphene (BLG) by using spatially resolved electron energy loss spectroscopy (EELS) with a monochromated electron source. We correlated the twist-angle-dependent energy band hybridization with Moire superlattices and the corresponding optical absorption peaks. The optical absorption peak originates from the excitonic transition between the hybridized van Hove singularities (vHSs), which shifts systematically with the twist angle. We then proved that the BLG decouples when a monolayer of metal chloride is intercalated in its van der Waals (vdW) gap, and results in the elimination of the vHS peak.
Diversity and Inclusion for Digital Humanists (Proposal for Ottawa 2020) (Abstract)

description: Abstract for DH2020 (Ottawa; later DH online) This workshop seeks to create awareness of diversity and cultural differences, as well as to
 present strategies for successful inclusion and the development of fairer environments. These
 factors are especially important within the Digital Humanities because of its emphasis on
 collaborative work which brings together different individuals. Moreover, our work has shown
 that in Digital Humanities, where there could be many different voices, most of the power and
 prestige remain centralized in the Global-North, in Anglophone countries. 1 This is not surprising
 considering the general state of academia as a mostly male, mostly white environment
 (Johnsrud and Des Jarlais 1994, Towsend 2013). For this reason, it’s essential to work with
 individuals to foster a richer environment, to change behaviours, and to challenge prejudices.

description: It is well known that beamloading effects in acceler- ating cavities can have a serious impact on the beam quality. In order to prevent emittance growth and to keep beam loss low during acceleration, detailed simu- lations are necessary to evaluate the effects on the cavity and its low level RF feedback systems. This situation is aggravated by the fact that in a SIS100 scenario two out of ten buckets have to stay empty. Up to now the closed loop performance of the overall cavity system is still an open topic. Therefore a detailed study has been started.

description: Aberrant thalamocortical connectivity occurs together with visual hallucinations in various pathologies and drug-induced states, highlighting the need to better understand how thalamocortical interactions may contribute to hallucinatory phenomena. Flicker light stimulation (FLS) at 10-Hz reliably and selectively induces transient visual hallucinations in healthy participants. Arrhythmic flicker elicits fewer hallucinatory effects while delivering equal amounts of visual stimulation, together facilitating a well-controlled experimental setup to investigate the neural correlates of visual hallucinations driven by flicker rhythmicity. Using rhythmic and arrhythmic FLS during fMRI scanning, we found that rhythmic FLS elicited stronger activation in higher order visual cortices compared with arrhythmic control. Consistently, we found that rhythmic flicker selectively increased connectivity between ventroanterior thalamic nuclei and higher order visual cortices, which was also positively associated with the subjective intensity of visual hallucinatory effects. As these thalamic and cortical areas do not receive primary visual inputs, it suggests that the thalamocortical connectivity changes relate to a higher order function of the thalamus, such as in the coordination of cortical activity. In sum, we present novel evidence for the role of specific thalamocortical interactions with ventroanterior nuclei within visual hallucinatory experiences. Importantly, this can inform future clinical research into the mechanistic underpinnings of pathologic hallucinations.

description: The governing equations for the surface phase, in the form established by BAM are developed in the second chapter. These equations are unique in that the surface is treated as a separate entity, with it's own differential equations and surface variables, the bulk phases entering primarily as boundary conditions. In the third chapter the surface equations are used to describe the surface instability of a system first investigated experimentally and theoretically by Linde. Our linear stability analysis, based on the surface balance equations, can extract the stability relations among the surface variables and the rate of energy input, whereas earlier studies had been less successful. In the fourth chapter, the patterns formed in the well-known Benard system are studied using a "finite-difference" representation of coupled nonlinear hydrodynamic equations, representing the system. Surface dynamics play a very significant role in the behavior of this system and when incorporated in the finite difference description of the bulk, one can readily demonstrate the complex interplay of surface and bulk effects. In chapter five we investigate the flow of a gas "bubble" which leaves a thin film as it displaces the liquid between two parallel plates. The finite difference representation of the hydrodynamic equations is restricted to two dimensions but provides not only a description of the movement of the curved gas-liquid interface, but also yields flow patterns in the bulk and at the surface. The interfacial conditions can be varied very quickly within the numerical program and the bubble behavior is studied systematically under a wide range of physical constraints. The thesis concludes, in chapter six, with a discussion of the significance of our results and comments on applications of the equations and computer code developed.

description: We report on 2 fossil groups of galaxies at z=0.425 and 0.372 discovered in the Cosmic Evolution Survey (COSMOS) area. Selected as X-ray extended sources, they have total masses (M_200) of 1.9(+/-0.41)E13 and 9.5(+/-0.42)E13 M_sun, respectively, as obtained from a recent X-ray luminosity-mass scaling relation. The lower mass system appears isolated, whereas the other sits in a well-known large-scale structure (LSS) populated by 27 other X-ray emitting groups. The identification as fossil is based on the i-band photometry of all the galaxies with a photo-z consistent with that of the group at the 2-sigma confidence level and within a projected group-centric distance equal to 0.5R_200, and i_AB<=22.5-mag limited spectroscopy. Both fossil groups exhibit high stellar-to-total mass ratios compared to all the X-ray selected groups of similar mass at 0.3<=z<=0.5 in the COSMOS. At variance with the composite galaxy stellar mass functions (GSMFs) of similarly massive systems, both fossil group GSMFs are dominated by passively evolving galaxies down to M^stars~1E10 M_sun (according to the galaxy broad-band spectral energy distributions). The relative lack of star-forming galaxies with 1E10<=M^stars<=1E11 M_sun is confirmed by the galaxy distribution in the b-r vs i color-magnitude diagram. Hence, the 2 fossil groups appear as more mature than the coeval, similarly massive groups. Their overall star formation activity ended rapidly after an accelerated build up of the total stellar mass; no significant infall of galaxies with M^stars>=1E10 M_sun took place in the last 3 to 6 Gyr. This similarity holds although the 2 fossil groups are embedded in two very different density environments of the LSS, which suggests that their galaxy populations were shaped by processes that do not depend on the LSS. However, their progenitors may do so. ...

description: We measure the superconducting transition of YIn$_3$ by resistivity, susceptibility, and specific heat. Despite using high-quality single-crystal samples, the transitions detected by the three techniques are shifted from each other in temperature, suggesting a region of filamentary superconductivity. We discuss the possible implications for filamentary superconductivity in unconventional superconductors.

description: The survey formed part of a project investigating factors affecting migration within a metropolitan region, particularly flows between the inner city and other areas, the welfare effects of such movement and constraints on potential movers. Extended interviews were conducted with three population groups - recent movers, potential movers and non-movers - in each of 6 areas within the London region. The areas comprised 2 sets of inner London boroughs, outer London boroughs and O.M.A. towns, one along a N.W. radial and one along a S.E. radial from central London. The aims of the survey were to provide specific information on the considerations affecting individual migration decisions; to make comparisions between the situations, attitudes and characteristics of those who had not moved; to investigate the process of decision-making by actual and potential migrants; and to identify any significant changes in welfare resulting from a move.

description: In this contribution we present a noncanonical phase-space noncommutative (NC) extension of a Kantowski Sachs (KS) cosmological model to describe the interior of a Schwarzschild black hole (BH). We evaluate the thermodynamical quantities inside this NC Schwarzschild BH and compare with the well known quantities. We find that for a NCBH the temperature and entropy have the same mass dependence as the Hawking quantities for a Schwarzschild BH.
The continuation of the ‘primitive’ trope: an examination of an ongoing legacy

description: It is largely accepted that the term ‘primitive’ is no longer appropriate to use- whether in academia or in public life. The question has been raised however (Kuper 2005), of whether the ‘primitive trope’ continues to exist today, but in altered forms. To answer this question, it is crucial to understand the historical context of the development of the trope, the consequences of its perpetuation, and the spaces in which it is evidently still occurring. Through a mixture of interviews, archival research and literature studies, this thesis examines the changing nature of the ‘primitive trope’, specifically in how it has evolved within academic scholarship and in museum spaces. It questions classification practices within both of these fields, and queries the ramifications of supposedly ‘unbiased’ labels. Further, in line with decolonisation scholarship, this thesis seeks to critique current practices of ethnoarchaeology and history-writing disciplines. This project therefore explores the effect of connecting contemporary societies and their way of life with the prehistoric past. By questioning linear narratives of time based on an increasing trajectory of development, the thesis highlights how contemporary communities are often located ‘outside of time’. My thesis does so with a focus on West Papuan and Papuan material culture and its representation given the centrality of material culture to categorisations of the past and ideas surrounding development.

description: The surface composition of charged Lennard-Jones clusters A$_N^{n+}$, composed of N particles (55 \leq N \leq 1169) among which n are positively charged with charge q, thus having a net total charge Q = nq, is investigated by Monte Carlo with Parallel Tempering simulations. At finite temperature, the surface sites of these charged clusters are found to be preferentially occupied by charged particles carrying large charges, due to Coulombic repulsions, but the full occupancy of surface sites is rarely achieved for clusters below the stability limit defined in this work. Large clusters (N = 1169) follow the same trends, with a smaller propensity for positive particles to occupy the cluster surface at non-zero temperature. We show that these charged clusters rather behave as electrical spherical conductors for the smaller sizes (N \leq 147) but as spheres uniformly charged in their volume for the larger sizes (N = 1169).
