description: This workshop will focus on the development and implementation of workflows for digital curation, focusing specifically on those that incorporate open-source software. The facilitators are part of the Open Source Software Archival Workflow (OSSArcFlow) project, which brings together researchers, developers of three major OSS digital stewardship systems, and digital stewards at twelve partner institutions including government archives, research institutes, and academic and public libraries. This is workshop is intended to be a very inclusive and interactive event. We will ask participants to submit short (1-2 pages) summaries in advance of some activities or challenges that they would like to present. Such submission will not be required, but it will be strongly encouraged. We will rely on the designated speakers to provide brief introductory remarks to motivate the main issues and guide the discussions. Participants who submitted summaries will then give short presentations We, as the facilitators, will then run break-out discussions in order to allow all participants to collectively identify areas of potential alignment or differences that they would like to explore further.

description: Based on the relationship between thermodynamics and gravity we propose, with the aid of Verlinde's formalism, an alternative interpretation of the dynamical evolution of the Friedmann-Robertson-Walker Universe. This description takes into account the entropy and temperature intrinsic to the horizon of the universe due to the information holographically stored there through non-gaussian statistical theories proposed by Tsallis and Kaniadakis. The effect of these non-gaussian statistics in the cosmological context is change the strength of the gravitational constant. In this paper, we consider the $w$CDM model modified by the non-gaussian statistics and investigate the compatibility of these non-gaussian modification with the cosmological observations. In order to analyze in which extend the cosmological data constrain these non-extensive statistics, we use type Ia supernovae, baryon acoustic oscillations, Hubble expansion rate function and the linear growth of matter density perturbations data.

description: A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV with ALICE. This so-called Gaussian Estimator allows for the first time the study of these quantities without the influence of correlations between different flow amplitudes. The centrality dependence of various correlations between two, three and four symmetry planes is presented. The ordering of magnitude between these symmetry plane correlations is discussed and the results of the Gaussian Estimator are compared with measurements of previously used estimators. The results utilizing the new estimator lead to significantly smaller correlations than reported by studies using the Scalar Product method. Furthermore, the obtained symmetry plane correlations are compared to state-of-the-art hydrodynamic model calculations for the evolution of heavy-ion collisions. While the model predictions provide a qualitative description of the data, quantitative agreement is not always observed, particularly for correlators with significant non-linear response of the medium to initial state anisotropies of the collision system. As these results provide unique and independent information, their usage in future Bayesian analysis can further constrain our knowledge on the properties of the QCD matter produced in ultrarelativistic heavy-ion collisions.

description: In a domain dealing with risks associated with the often quoted fast-changing technological landscape, it is surprising that one of the main tools we rely on has been more or less stable for so long. More or less? DROID signature patterns undergo changes as identification methods improve. The question at hand is how frequent those changes and updates are and what their impact is. The poster presents the findings of a brief study taking a closer look at DROID signature pattern changes over the course of time.
Evaluating the role of transporters in the anticancer efficacy of metformin in endometrial cancer
Creators: name: Damery, Erin F.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Recent studies show that the anti-diabetic drug metformin exhibits anticancer effects
against a broad spectrum of cancers including endometrial cancer. Due to its hydrophilic nature
and net positive charge at physiological pH, metformin requires cation-selective transporters to
enter cells. This study investigated the expression of metformin transporters in human
endometrial cancer cell lines, and the role of these transporters in metformin cellular uptake and
accumulation in two human endometrial cancer cell lines, Ishikawa and ECC-1. Total RNA
isolated from these two cell lines was subjected to real time polymerase chain reaction (RT-PCR)
to determine the expression levels of common cation-selective transporters that are known to
transport metformin. MATE 1 and 2 were the predominant transporters in Ishikawa and ECC-1
cells while OCT 1-3 expression in both cell lines was relatively poor. Time-dependent [14C]
metformin uptake into Ishikawa and ECC-1 cell lines was measured by quantifying intracellular
radioactivity. To demonstrate the role of transporters in the uptake of metformin in these two cell
lines, metformin uptake was measured in the presence and absence of cation-selective transporter
inhibitors. Metformin uptake was saturated in both cell lines, and transporter inhibitors decreased
metformin uptake in Ishikawa cells. RT-PCR results demonstrate that Ishikawa and ECC-1 cells
are relevant in vitro models for investigating metformin treatment in endometrial cancer because
expression of metformin transporters in human endometrial cancer tissues is comparable to that
observed in endometrial cancer cell lines. The finding that metformin uptake is decreased by
inhibitors only in Ishikawa cells warrants further study.

description: We review the reservoirs of methane clathrates that may exist in the different bodies of the Solar System. Methane was formed in the interstellar medium prior to having been embedded in the protosolar nebula gas phase. This molecule was subsequently trapped in clathrates that formed from crystalline water ice during the cooling of the disk and incorporated in this form in the building blocks of comets, icy bodies, and giant planets. Methane clathrates may play an important role in the evolution of planetary atmospheres. On Earth, the production of methane in clathrates is essentially biological, and these compounds are mostly found in permafrost regions or in the sediments of continental shelves. On Mars, methane would more likely derive from hydrothermal reactions with olivine-rich material. If they do exist, martian methane clathrates would be stable only at depth in the cryosphere and sporadically release some methane into the atmosphere via mechanisms that remain to be determined.
Do serum estrogen levels affect the antibody response to flu vaccines in post-menopausal women?

Year: 2017

description: Public health and the improvement of human health has been a topic of interest for centuries – even more so in current society. Preventative healthcare, specifically, has become a focus in recent years. Vaccines are one of the primary methods in which health officials attempt to improve both individual and collective human health before any issues even arise. That is why it is imperative to take into account any factors that may impede the ability of vaccines to perform to their full capacity. This includes the presence – or lack thereof – of certain hormones, like estrogen. Obesity has also been shown to have a negative effect on antibody response to the flu vaccine (Sheridan et al.). Post-menopausal women have been shown to be especially susceptible to numerous health related consequences like obesity (Colombel et al.) and decline in immune responses, which can possibly be attributed to estrogen deprivation (Gameiro et al.). This association is further supported by a mouse model study by Nguyen et al. which showed hormone replacement therapy to have a positive effect on antibody response to the influenza vaccine in post-menopausal mice. Because a decline in estrogen is thought to possibly be the cause of a declined antibody response to the flu vaccine in the mouse model, we hypothesized that post-menopausal women with less estrogen will have a decreased antibody response to the 2014-2015 H1N1 flu vaccine. Furthermore, though obese post-menopausal women have been shown to have higher levels of estrogen than non-obese post-menopausal women – opposite trend of pre-menopausal women (Freeman et al.) – we additionally hypothesized that obese post-menopausal women will also have a decreased immune response to the 2014-2015 H1N1 flu vaccine. To test these hypotheses, we collected pre and 30 days post influenza vaccine serum samples from twenty-four post-menopausal. Enzyme-linked immunosorbent assays (ELISA) were conducted on the pre- and post-vaccination serum samples and their antibody responses and
estrogen levels were assessed and compared. As expected, mean estrogen concentrations increased with increasing BMI categorization. Additionally, overweight post-menopausal women had a greater mean antibody response as opposed to healthy weight or obese post-menopausal women. However, this data was not significant. Though this data was not significant, it should be repeated with a larger sample size and with second blood draws done more than 30 days post-vaccination. Another potential expansion of this study is to include data from pre-menopausal women, as well, since there may be more variations in estrogen in their serum.
LA FORFETIZZAZIONE LEGALE DEL DANNO RISARCIBILE

Publisher: name: Universit� degli Studi di Milano
Year: 2011

description: ABSTRACT The topicality of the debate concerning the possibility of civil liability to have a punitive function in our legal system can also be dealt with from the perspective of the legal predetermination of restorable damages, which is topic less studied by legal scholars than penalty clauses. The first chapter contains a survey of the most relevant cases of legal predetermination of restorable damages aimed at questioning the relevant structure, functions and major issues. Thus, the conclusion is reached that the concept of legally liquidated damages is only descriptive, being an instrument by which the legislator intends to realize heterogeneous functions. Accordingly, it is impossible to have only one legal category which is subject to a sole discipline. In the second chapter, the cases of legal predetermination of damages are divided in three groups, according to the prevalent function that the restoration of damages has: compensative, punitive or indemnitary. The conclusion is that civil liability may have a punitive function, that must be supported by a provision of law, in absence of which the judge cannot deviate from a merely compensative principle. The classification in three groups, the analysis of the structure and the functions of legal predetermination of damages allow to answer to some practical questions, concerning the legal predetermination of damages and infer some practical suggestions for a correct use of such instruments.

description: We study the helical edge states of a two-dimensional topological insulator without axial spin symmetry due to the Rashba spin-orbit interaction. Lack of axial spin symmetry can lead to so-called generic helical edge states, which have energy-dependent spin orientation. This opens the possibility of inelastic backscattering and thereby nonquantized transport. Here we find analytically the new dispersion relations and the energy dependent spin orientation of the generic helical edge states in the presence of Rashba spin-orbit coupling within the Bernevig-Hughes-Zhang model, for both a single isolated edge and for a finite width ribbon. In the single-edge case, we analytically quantify the energy dependence of the spin orientation, which turns out to be weak for a realistic HgTe quantum well. Nevertheless, finite size effects combined with Rashba spin-orbit coupling result in two avoided crossings in the energy dispersions, where the spin orientation variation of the edge states is very significantly increased for realistic parameters. Finally, our analytical results are found to compare well to a numerical tight-binding regularization of the model.

description: Multivariate time series forecasting with hierarchical structure is widely used in real-world applications, e.g., sales predictions for the geographical hierarchy formed by cities, states, and countries. The hierarchical time series (HTS) forecasting includes two sub-tasks, i.e., forecasting and reconciliation. In the previous works, hierarchical information is only integrated in the reconciliation step to maintain coherency, but not in forecasting step for accuracy improvement. In this paper, we propose two novel tree-based feature integration mechanisms, i.e., top-down convolution and bottom-up attention to leverage the information of the hierarchical structure to improve the forecasting performance. Moreover, unlike most previous reconciliation methods which either rely on strong assumptions or focus on coherent constraints only,we utilize deep neural optimization networks, which not only achieve coherency without any assumptions, but also allow more flexible and realistic constraints to achieve task-based targets, e.g., lower under-estimation penalty and meaningful decision-making loss to facilitate the subsequent downstream tasks. Experiments on real-world datasets demonstrate that our tree-based feature integration mechanism achieves superior performances on hierarchical forecasting tasks compared to the state-of-the-art methods, and our neural optimization networks can be applied to real-world tasks effectively without any additional effort under coherence and task-based constraints
"I do something different and extraordinary": U.S. Abortion Providers and Positive Identity Work
Creators: name: Baldiga, Amanda
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This study aims to answer two questions: how does the codification of restrictive state legislation affect the work that U.S abortion workers do; and what are the mechanisms of positive identity work used by abortion workers. Occupational identity is a major component of self-identity, and this is especially true of individuals who do ‘dirty’ or stigmatized work. The experience of stigma as a result of being an abortion worker, and the transformation of stigma into positive self-identity, has been documented in several qualitative studies. But what mechanisms of identity work facilitate this positive transformation of stigma? I find that abortion workers valorize their work and construct it as a necessary and normal part of health care. I interpret these mechanisms of identity work as restorative, and situate my findings in states with restrictive abortion laws.

description: Islandora currently generates and manages data describing periodic fixity verification for assets stored in its Fedora Commons 3.x repository. This data is stored and provided to users as PREMIS 2 "Fixity Check" events. The next generation of Islandora, a complete redevelopment of the platform, is underway, and the migration of PREMIS data from current implementations to the new platform must ensure an integral chain of preservation. In addition to this platform migration, fixity auditing in the new Islandora will generate PREMIS 3 "Fixity Check" events from a Fedora 5 repository, which provides different mechanisms for verifying asset fixity than Fedora 3 provides. While PREMIS 2 and PREMIS 3 fixity check events are semantically identical, the new Islandora must be able to represent both data it generates and legacy data in PREMIS 3 RDF serializations.

description: We consider theoretically a driven-dissipative quantum many-body system consisting of an atomic ensemble in a single-mode optical cavity as described by the open Tavis-Cummings model. In this hybrid light-matter system the interplay between coherent and dissipative processes leads to superradiant pulses with a build-up of strong correlations, even for systems comprising hundreds to thousands of particles. A central feature of the mean-field dynamics is a self-reversal of two spin degrees of freedom due to an underlying time-reversal symmetry, which is broken by quantum fluctuations. We demonstrate a quench protocol that can maintain highly non-Gaussian states over long time scales. This general mechanism offers interesting possibilities for the generation and control of complex fluctuation patterns, as suggested for the improvement of quantum sensing protocols for dissipative spin-amplification.

The Locus of Plane Quartics with A Hyperflex

Subjects: subject: Algebraic Geometry (math.AG)

description: Using the results of Dalla Piazza, Fiorentino and Salvati Manni, we determine an explicit modular form defining the locus of plane quartics with a hyperflex among all plane quartics. As a result, we provide a direct way to compute the divisor class of the locus of plane quartics with a hyperflex within $\overline{\mathcal{M}_3}$, first obtained by Cukierman in 1989. Moreover, the knowledge of such an explicit modular form also allows us to describe explicitly the boundary of the hyperflex locus in $\overline{\mathcal{M}_3}$. As an example, we show that the locus of banana curves (two irreducible components intersecting at two nodes) is contained in the closure of the hyperflex locus. We also identify an explicit modular form defining the locus of Clebsch quartics and use it to recompute the class of this divisor, first obtained by Ottaviani and Sernesi.

The Educational Effects of Parental Incarceration
Creators: name: McCready, Laura K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This paper explores the intergenerational educational consequences of incarceration. Through a
structural equation model with latent variables, it analyzes four waves of data from the National
Longitudinal Study of Adolescent Health (Add Health) to explore how paternal incarceration
influences children’s school trouble in their mid-high school years. The data show that the
children of the prison boom are socioeconomically vulnerable; they are more likely to be from
minority racial/ethnic groups, to have non-traditional family structures, and to be from low-income
families. Paternal incarceration negatively affects adolescents’ performance in school
through decreased family earnings, altered family structures, reduced paternal involvement in the
child’s life, and strain on the child’s mental health. It also harms school performance directly,
theoretically through social stigma. By exploiting an idiosyncrasy of the Add Health data, this
model identifies and quantifies a paternal incarceration effect that acts separately from the effect
of paternal criminality. Punishment in America reverberates across generations.

description: Gaussian network model(GNM) and anisotropic network model(ANM) are some of the most popular methods for the study of protein flexibility and related functions. In this work, we propose generalized GNM(gGNM) and ANM methods and show that the GNM Kirchhoff matrix can be built from the ideal low-pass filter, which is a special case of a wide class of correlation functions underpinning the linear scaling flexibility-rigidity index(FRI) method. Based on the mathematical structure of correlation functions, we propose a unified framework to construct generalized Kirchhoff matrices whose matrix inverse leads to gGNMs, whereas, the direct inverse of its diagonal elements gives rise to FRI method.With this connection,we further introduce two multiscale elastic network models, namely, multiscale GNM(mGNM) and multiscale ANM(mANM), which are able to incorporate different scales into the generalized Kirchkoff matrices or generalized Hessian matrices.We validate our new multiscale methods with extensive numerical experiments. We illustrate that gGNMs outperform the original GNM method in the B-factor prediction of a set of 364 proteins.We demonstrate that for a given correlation function, FRI and gGNM methods provide essentially identical B-factor predictions when the scale value in the correlation function is sufficiently large.More importantly,we reveal intrinsic multiscale behavior in protein structures. The proposed mGNM and mANM are able to capture this multiscale behavior and thus give rise to a significant improvement of more than 11% in B-factor predictions over the original GNM and ANM methods. We further demonstrate benefit of our mGNM in the B-factor predictions on many proteins that fail the original GNM method. We show that the present mGNM can also be used to analyze protein domain separations. Finally, we showcase the ability of our mANM for the simulation of protein collective motions.

description: The study focuses on the nexus between national higher education policies/instruments and their impact on university governance at the institutional level in the context of the European Higher Education policy. The paper offers a comparative analysis of university governance models and formation of an ‘archetype’ at HEIs. The study is conducted in two countries, Germany and Georgia, which gives an opportunity to observe and compare how European HE policy is interpreted and implemented in an old EU state and a post-soviet bloc state. It looks at the theoretical framework of constructing university as an organization and its implementation in practice describing the shift from state-centered governance to self-governance, autonomy and academic freedom. The paper also examines the role of Quality Assurance (QA) as a tool to ensure quality of HE provision at a university level and enquires what role QA plays in organizational culture. The research has an exploratory character aiming to discover how European HE Policy has been interpreted and implemented in the countries taking into account different cultural and historical background.

description: Machine reading comprehension (MRC) is an important area of conversation agents and draws a lot of attention. However, there is a notable limitation to current MRC benchmarks: The labeled answers are mostly either spans extracted from the target corpus or the choices of the given candidates, ignoring the natural aspect of high-quality responses. As a result, MRC models trained on these datasets can not generate human-like responses in real QA scenarios. To this end, we construct a new dataset called Penguin to promote the research of MRC, providing a training and test bed for natural response generation to real scenarios. Concretely, Penguin consists of 200k training data with high-quality fluent, and well-informed responses. Penguin is the first benchmark towards natural response generation in Chinese MRC on a relatively large scale. To address the challenges in Penguin, we develop two strong baselines: end-to-end and two-stage frameworks. Following that, we further design Prompt-BART: fine-tuning the pre-trained generative language models with a mixture of prefix prompts in Penguin. Extensive experiments validated the effectiveness of this design.

Geographic Complex Adaptive Systems: Mapping the Ontology of Modern Mass Killing
Creators: name: Langberg, Sean
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: What is the ontology of modern mass killing? Why does mass killing occur in some conflicts
and not others? Much of the academic and policy literature uses methods that emphasize
categorization that manifests as stages or discrete lists. In this paper, I argue the complexity of
human systems, including mass killing systems, deserves a greater role in prevention research
and post facto analysis and I posit a hybrid schematic called geographic complex adaptive
systems that combine complex adaptive systems and geographies of power. They are explicitly
geographic and utilize the unique ways that geographers see human systems - spatially,
integrated, and constructed. I outline how the schematic could apply to the case of mass killing
in Democratic Republic of the Congo during the Second Congo War. The case study offers
support for the position that long-term power shifts in systems present opportunities for mass
killing.

Hawking radiation via tunneling from the spacetime of a spinning cosmic string black holes
Creators: name: Jusufi, Kimet
Publisher: name: arXiv
Year: 2015
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper, we study Hawking radiation as a massless particles tunneling process across the event horizon from the Schwarzschild and Reissner-Nordström black holes pierced by an infinitely long spinning cosmic string and a global monopole. Applying the WKB approximation and using a generalized Painlevé line element for stationary axisymmetric spacetimes, also by taking into account that the ADM mass of the black hole decreases due to the presence of topological defects, it is shown that the Hawking temperature remains unchanged for these black holes. The tunneling of charged massive particles from Reissner-Nordström black holes is also studied, in both cases the tunneling rate is related to the change of the Bekenstein-Hawking entropy. The results extend the work of Parikh and Wilczek and are consistent with an underlying unitary theory.
The galaxy luminosity function in groups and clusters: the faint-end upturn and the connection to the field luminosity function

description: We characterize the luminosity functions of galaxies residing in $z\sim0$ groups and clusters over the broadest ranges of luminosity and mass reachable by the Sloan Digital Sky Survey. Our measurements cover four orders of magnitude in luminosity, down to about $M_r=-12$ mag or $L=10^7\,L_\odot$, and three orders of magnitude in halo mass, from $10^{12}$ to $10^{15} \, {\rm M}_\odot$. We find a characteristic scale, $M_r\sim-18$ mag or $L\sim10^9\, L_\odot$, below which the slope of the luminosity function becomes systematically steeper. This trend is present for all halo masses and originates mostly from red satellites. This ubiquitous faint-end upturn suggests that it is formation, rather than halo-specific environmental effect, that plays a major role in regulating the stellar masses of faint satellites. We show that the satellite luminosity functions can be described in a simple manner by a double Schechter function with amplitudes scaling with halo mass over the entire range of observables. Combining these conditional luminosity functions with the dark matter halo mass function, we accurately recover the entire field luminosity function over 10 visual magnitudes and reveal that satellite galaxies dominate the field luminosity function at magnitudes fainter than $-17$. We find that the luminosity functions of blue and red satellite galaxies show distinct shapes and we present estimates of the stellar mass fraction as a function of halo mass and galaxy type. Finally, using a simple model, we demonstrate that the abundances and the faint-end slopes of blue and red satellite galaxies can be interpreted in terms of their formation history, with two distinct modes separated by some characteristic time.

subject: ipres2018

description: ARKs are a widely used to ensure persistent publicly resolvable links to objects. The ARK ecosystem is crucial to long-term access to digital objects. Over 550 institutions (research, not-for-profit, private, government) across the world have registered to use ARKs. They’ve created an estimated 175 million ARKs with publicly resolvable links to objects (digital, physical, people, places, etc.). This talk will provide an update on "ARKs in the Open", a collaboration aimed at building an open, international community around Archival Resource Keys (ARKs) and their use as persistent identifiers in the open scholarly ecosystem.

description: In this paper, we discuss a connection between different linearizations for non-abelian analogs of the second Painlevé equation. For each of the analogs, we listed the pairs of the Harnard-Tracy-Widom (HTW), Flaschka-Newell (FN), and Jimbo-Miwa (JM) types. A method for establishing the HTW-JM correspondence is suggested. For one of the non-abelian analogs, we derive the corresponding non-abelian generalizations of the monodromy surfaces related to the FN- and JM-type linearizations. A natural Poisson structure associated with these monodromy surfaces is also discussed.

description: I aim to replicate the main findings of the prior study "Sex(ism) doesn't sell: Disentangling the effects of nudity and sexism in advertising" (Hertel et al., 2022). Drawing from recent findings, I expect sexism as well as nudity to have negative effects on recipients' attitude towards the ad and the brand. Furthermore I expect a specific rank order (see hypotheses) and an interaction of nudity and sexism. Using different and more standardized stimuli (e.g., only one product category, holding product fit and brand familiarity constant) I want to conceptually replicate prior findings, whilst measuring attitude towards the ad and the brand more reliably.

description: We describe the luminosity function, based on Sersic fits to the light profiles, of CMASS galaxies at z ~ 0.55. Compared to previous estimates, our Sersic-based reductions imply more luminous, massive galaxies, consistent with the effects of Sersic- rather than Petrosian or de Vaucouleur-based photometry on the Sloan Digital Sky Survey (SDSS) main galaxy sample at z ~ 0.1. This implies a significant revision of the high mass end of the correlation between stellar and halo mass. Inferences about the evolution of the luminosity and stellar mass functions depend strongly on the assumed, and uncertain, k+e corrections. In turn, these depend on the assumed age of the population. Applying k+e corrections taken from fitting the models of Maraston et al. (2009) to the colors of both SDSS and CMASS galaxies, the evolution of the luminosity and stellar mass functions appears impressively passive, provided that the fits are required to return old ages. However, when matched in comoving number- or luminosity-density, the SDSS galaxies are less strongly clustered compared to their counterparts in CMASS. This rules out the passive evolution scenario, and, indeed, any minor merger scenarios which preserve the rank ordering in stellar mass of the population. Potential incompletenesses in the CMASS sample would further enhance this mismatch. Our analysis highlights the virtue of combining clustering measurements with number counts.

206.08 LT12 Fedora & Digital Preservation
Creators: name: Wilcox, David
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: ad hoc
subject: Ad Hoc: Lightning Talks
subject: ipres2018

description: Fedora has been closely associated with digital preservation from the very beginning, but this relationship has evolved over time. Fedora was originally an XML-based system, and digital objects were preserved, in part, by encoding them in Fedora Object XML (FOXML), which included everything about the object: metadata, its relationships to other objects, its version history, and its audit trail. But no software application lasts forever, and FOXML is not a standard that is known anywhere outside the Fedora community, making the task of reading and understanding the contents of a Fedora repository absent the Fedora application quite difficult. Over time, we have shifted to adopting well-known, non-application-specific standards, as well as providing a mechanism for exporting repository contents to disk using standard serialization options. At the same time, we have moved beyond the conception of Fedora as a preservation system to one that supports and enables an overall preservation strategy. This means Fedora has a set of features that support digital preservation, but it also provides well-documented integration points and patterns for connecting Fedora with other applications and services in a larger digital preservation environment. This lightning talk will briefly describe the ways in which Fedora’s approach to digital preservation have changed over time, and how Fedora can support an overall digital preservation strategy.
Unfriending and Unfollowing Practices of College Student Users of Facebook

description: Facebook has become an integral part of college students’ lives within the United
States. This study aims to provide information on how college students feel and react to
information overload, information avoidance, and their privacy concerns. It also aims to
find any gender differences between men and women regarding how they unfriend and
unfollow other users on Facebook and what their reasoning is. The findings suggest that
college students do feel a sense of information avoidance on Facebook that leads them to
unfriend or unfollow offending users. Some mentioned feelings of information overload,
but it was not a concern that worried them. Many of the participants mentioned that
privacy concerns were important to them, but they would rather censor themselves than
unfriend or unfollow users that they did not want to see their postings. Generally, the
participants held negative attitudes towards Facebook, but felt obligated to keep using the
social media site for convenience and to find out information about others. There were
no clear differences between men and women in their unfriending and unfollowing
practices.

description: Social media platforms contain abundant data that can provide comprehensive knowledge of historical and real-time events. During crisis events, the use of social media peaks, as people discuss what they have seen, heard, or felt. Previous studies confirm the usefulness of such socially generated discussions for the public, first responders, and decision-makers to gain a better understanding of events as they unfold at the ground level. This study performs an extensive analysis of COVID-19-related Twitter discussions generated in Australia between January 2020, and October 2022. We explore the Australian Twitterverse by employing state-of-the-art approaches from both supervised and unsupervised domains to perform network analysis, topic modeling, sentiment analysis, and causality analysis. As the presented results provide a comprehensive understanding of the Australian Twitterverse during the COVID-19 pandemic, this study aims to explore the discussion dynamics to aid the development of future automated information systems for epidemic/pandemic management.

description: Many of the current digital preservation initiatives in Canada are focused on the preservation of research data. CARL’s Portage is a national, library-based research data management network leading a national effort to develop a research data preservation service. Portage’s Preservation Experts Group (PEG) has been established to advise Portage on the long-term stewardship and access to research data and metadata. PEG feels that a collaborative effort is required to overcome significant gaps and challenges and to build the infrastructure needed to create a sustainable research data preservation environment in Canada. This poster describes a disaggregated digital preservation strategy proposed by PEG. The proposed approach is based on OO-IO model and covers all core-functions, as articulated in the OAIS model, using a disaggregated approach through collaboration and coordination of services.
