description: Video OCR is a technique that can greatly help to locate the topics of interest in video via the automatic extraction and reading of captions and annotations. Text in video can provide key indexing information. Recognizing such text for search application is critical. Major difficult problem for character recognition for videos is degraded and deformated characters, low resolution characters or very complex background. To tackle the problem preprocessing on text image plays vital role. Most of the OCR engines are working on the binary image so to find a better binarization procedure for image to get a desired result is important.Accurate binarization process minimizes the error rate of video OCR.

description: This thesis, resting on primary documentary evidence and numerous secondary sources, will expand on recent work illustrating the importance of British Lend-Lease aid on the Eastern Front in 1941. It also will demonstrate that this aid fundamentally weakened the British military position in the Middle East and Far East. A close study of the numbers, types and timing of shipments of aircraft and armour to various theatres will show for the first time in quantifiable form how the British allocated their material and, by implication, what else they could have done. It will tally costs and benefits, and assess how good British decisions were from the perspective of their own interests, and those of the Allied cause. Finally, it will show that from late 1941 to 1942, Britain gave more than it got from Lend-Lease.

description: Hauptziel von Wissenschaft ist gemeinhin die Suche nach Wahrheit und rationaler Argumentation. Sie will Antworten auf die Frage danach, was gegeben ist. Science sucht das Wissen über die Welt, wobei die Frage nach der theoretischen oder praktischen Evidenzbasierung eine eminente Rolle spielt. Als Repräsentation dessen, was gegeben ist, gilt nur das, was bestimmten rationalen Regeln folgt. Dabei bezieht sich das Verständnis von Evidenz gerade auf das Gegenteil eines wissenschaftlichen Modus: Unter Evidenz wird ein unhinterfragbarer Satz verstanden. Doch Wissenschaft versteht sich als stets erweiterbar, nie abgeschlossen, stets nur zu einem bestimmten Moment gültig. Umgekehrt meint Fiktion eine erschaffene Welt etwa in Malerei, im Film oder in der Literatur. Mehr noch, im Kontext von Science-Fiction geht es darum, Welten zu schaffen, die in gewisser Weise zeitlich und räumlich von der bestehenden Welt entrückt sind. Das Ergebnis sind fiktionale Welten, in denen futuristische Lebensumstände oder Begegnungen mit extraterrestrischen Lebewesen verhandelt werden.

description: Using a dataset containing nearly 500,000 courses taken by over 40,000 community and technical college students in Washington State, this study examines how well students adapt to the online environment in terms of their ability to persist and earn strong grades in online courses relative to their ability to do so in face-to-face courses. While all types of students in the study suffered decrements in performance in online courses, some struggled more than others to adapt: males, younger students, Black students, and students with lower grade point averages. In particular, students struggled in subject areas such as English and social science, which was due in part to negative peer effects in these online courses.

description: The speed of CPUs and memories has historically outstripped I/O, but emerging network and storage technologies promise to invert this relationship. As a result, fundamental assumptions about the role of the operating system in computing systems will have to change. We propose an operating and application architecture that removes the CPU and memory from the path of high-speed I/O. In our model, the operating system becomes a data-flow manager and applications merely direct this flow instead of directly participating in it. Our proof-of-concept prototype, which we implemented on an FPGA board, nearly doubled the throughput of a simple cryptographic networking application, suggesting our model can provide a substantial improvement.

description: Several models of dark matter motivate the concept of hidden sectors consisting of SU(3)_C x SU(2)_L x U(1)_Y singlet fields. The interaction between our and hidden matter could be transmitted by new abelian U'(1) gauge bosons A' mixing with ordinary photons. If such A's with the mass in the sub-GeV range exist, they would be produced through mixing with photons emitted in two photon decays of η,η' neutral mesons generated by the high energy proton beam in a neutrino target. The A's would then penetrate the downstream shielding and be observed in a neutrino detector via their A'-> e+e- decays. Using bounds from the CHARM neutrino experiment at CERN that searched for an excess of e+e- pairs from heavy neutrino decays, the area excluding the γ- A' mixing range 10^{-7} < ε< 10^{-4} for the A' mass region 1 < M_A' <500 MeV is derived. The obtained results are also used to constrain models, where a new gauge boson X interacts with quarks and leptons. New upper limits on the branching ratio as small as Br(η-> γX) < 10^{-14} and Br(η' -> γX) < 10^{-12} are obtained, which are several orders of magnitude more restrictive than the previous bounds from the Crystal Barrel experiment.

In Silico Ligand Design to Inhibit Oligomerisation and Cu+ Redox Activity in Alzheimer’s Disease
Creators: name: Opare, Stanley
Publisher: name: Graduate Studies
Year: 2018
Subjects: subject: Education--Sciences

description: Alzheimer’s disease (AD) is a progressive disease of the brain. It leads to the loss of memory and thinking abilities. The toxicity has been associated with smaller oligomeric forms of beta amyloid peptide (beta amyloid). The speed of aggregation has been attributed to pH changes attributing fastest aggregation to pH ranging from 5 to 6. Generation of reactive oxidative species (ROS) has also been attributed to the cause of this disease. This process has been attributed to Fenton-like chemistry involving copper. Cu+ has been associated with reduction of O2 to O2•-; reduction of O2•- to H2O2; and further reduction of H2O2 to form HO•. Because of these, Cu+ was targeted in designing ligands that will bind stronger Cu+ than how much beta amyloid will. Beta amyloid complexes Cu+ using His13 and His14. Using quantum mechanical (QM) approach, the binding energy of both oxidation states of copper bound to two histidines and additional water molecules to complete the coordination where necessary (to model the interaction in Ab) were generated and the reduction potential estimated. Armed with this information, ligands were designed that mimic the Cu+ coordination in beta amyloid. The Gibbs free energies of both Cu+ and Cu2+ coordination to these ligands in addition to their reduction potentials were also calculated and compared to that in the model beta amyloid complex. The ligands were ranked accordingly and possible drug (ligand) candidates predicted. One of the ligand candidates (PI) was attached to a pseudopeptide called SGC1 which was designed to inhibit oligomerization. Molecular dynamics and umbrella sampling approaches were used to ascertain their inhibition of beta amyloid self oligomerization. By so doing this new pseudopeptide will serve both purposes of inhibiting oligomerization and generation of reactive oxidative species. Due to computational cost the region of beta amyloid that was used was the so called self recognition site and the region that binds to Cu+. This region covers from His13 to Asp23. This region is referred to as Rec and is used as a model for beta amyloid.

description: In a nation like Canada, attention to the diversity of clientele is essential for counsellors to practice ethically. Multicultural considerations have become a fourth force in counselling practice, with a multitude of models and frameworks suggesting how to enact cultural competence in counselling. Research on cultural competence has typically focused on the counsellor perspective. A limited number of studies have solicited client perspectives on their counsellor’s competence, and no current studies examining client self-reflections of their contributions to the counselling experience. My research contributed to the literature by taking a social constructivist, qualitative approach to investigating what clients find beneficial and not beneficial in navigating culture in the counselling context. The research included exploration of both their counsellors’ beliefs, attitudes, sayings, actions and other ways of being, and an introduction to clients’ self-reflection on their contributions to the counselling experience. Through the Enhanced Critical Incident Technique (ECIT), 10 university students identified incidents that helped, hindered, or were desired in order to navigate culture in the counselling context. Data analysis resulted in 12 categories that encapsulated the 162 incidents about counsellor factors: (a) creating safety, (b) empathy, (c) genuineness, (d) communication skills, (e) engagement, (f) counsellor-client bond, (g) cultural identities, (h) flexibility, (i) impacts of categorization, (j) general counselling competence, (k) professionalism, (l) contributions to client outcomes. The 9 incidents related to client contributions fit within one category: style of engagement. I synthesized the findings with existing literature to offer recommendations for counselling practice and education.

description: While the efficacy of exercise in the management of cardiovascular, lipid, glycemic, and other systemic disorders has been well documented and long studied, the beneficial effect of exercise on the central nervous system (CNS) has only recently gained substantial support from the literature. Exercise has been shown to initiate pleiotropic mechanisms that increase the functional acuity of many aspects of the CNS, protect against future pathology, and possibly reverse existing disability. While there has been significant study of the effect of exercise on the pathophysiology of neurodegenerative disorders and on general CNS well-being, there has been only limited study of exercise in demyelinating disorders, such as multiple sclerosis (MS), particularly with regard to whether exercise promotes reparative processes. In this thesis I investigate the effect of exercise on the regeneration of myelin in the lysolecithin model of focal demyelination. I show that exercise enhances oligodendrogenesis and the formation of myelin, substantially accelerating the remyelination process. I show that the activation of a transcriptional coactivation, peroxisome-proliferator activated receptor gamma coactivation 1 alpha (PGC1a), is enhanced by exercise and required for the acceleration of myelin thickening. I then show that exercise works in combination with clemastine, resulting in functionally complete remyelination of lysolecithin lesions. Moreover, the combination treatment preserves axons. Thus, exercise should have considerable clinical utility in disorders where demyelination is present. Finally, I detail a novel technique for visualizing oligodendrocytes in three-dimensions.

Asia is now experiencing a serious downturn as the result of falling consumption and exports, and an intensifying credit squeeze due to global deleveraging. Through appropriate monetary, financial, and public-investment policies, Asia can lead the world to recovery, in essence by replacing the declining consumption spending with increased public spending on critical goods and services (such as health and education) and public investments in sustainable infrastructure, including pollution control, sustainable energy systems, efficient water use, broadband connectivity, and other priority areas.

description: We introduce a real time version of the functional renormalization group which allows to study correlation effects on nonequilibrium transport through quantum dots. Our method is equally capable to address (i) the relaxation out of a nonequilibrium initial state into a (potentially) steady state driven by a bias voltage and (ii) the dynamics governed by an explicitly time-dependent Hamiltonian. All time regimes from transient to asymptotic can be tackled; the only approximation is the consistent truncation of the flow equations at a given order. As an application we investigate the relaxation dynamics of the interacting resonant level model which describes a fermionic quantum dot dominated by charge fluctuations. Moreover, we study decoherence and relaxation phenomena within the ohmic spin-boson model by mapping the latter to the interacting resonant level model.

description: By exploiting the object-oriented dynamic composability of modern document applications and formats, malcode hidden in otherwise inconspicuous documents can reach third-party applications that may harbor exploitable vulnerabilities otherwise unreachable by network-level service attacks. Such attacks can be very selective and difficult to detect compared to the typical network worm threat, owing to the complexity of these applications and data formats, as well as the multitude of document-exchange vectors. As a case study, this paper focuses on Microsoft Word documents as malcode carriers. We investigate the possibility of detecting embedded malcode in Word documents using two techniques: static content analysis using statistical models of typical document content, and run-time dynamic tests on diverse platforms. The experiments demonstrate these approaches can not only detect known malware, but also most zero-day attacks. We identify several problems with both approaches, representing both challenges in addressing the problem and opportunities for future research.
Contribution to the development of a tool to link Matlab constraint satisfaction platform to ANSYS structural models
Creators: name: Villiard, Caroline
Publisher: name: University of British Columbia
Year: 2011

description: Engineers have to deal with uncertainties as a challenge when pursuing the safest and most economical design. Several methods have been used over the years to deal with these uncertainties and to make this conceptual design phase more straight forward. Safety goals have been achieved due to safety coefficients found in design codes, but there is a lack of software tools to carry out risk and reliability analysis. Within the framework of University research, the novel idea of combining wood and steel as two structural members of mid-rise hybrid buildings is being studied. The need for an optimized design to start off the hybrid structure project led to this thesis, where the goal is to link the ANSYS structural analysis program to a Matlab platform for integrating probabilistic constraints. The methodology proposed by Loewen seeks to remedy the uncertainty issues encountered by engineers, and his Probability Constraint Satisfaction Program (PCSP) is the foundation of the Matlab platform developed more extensively here. This method involves subdividing the design space and estimating the potential of meeting the constraints according to the probability distribution of the data in each interval. An advantage output of this technique are design spaces combining probabilities of various data. The structural component of this thesis involves formatted files serving as input for ANSYS program were created to automatically model multistorey hybrid steel-wood structures. Some frameworks and a literature review introduce the pros and cons of this type of construction. Many issues are dealt with during the modeling phase whereas some are left to the future developing stage. Simplified examples leading to an understanding of the methodology developed to build an efficient link are shown to illustrate the essence of the research done. Additional computations were added to the programs script files and resulted in a powerful tool that was put to the test with two different examples- a simple hybrid frame and a multistorey steel structure. As a result of this work on the example structures, the PCSP method produced design spaces, presented to the reader.

Our poster will describe how we are improving accessibility across these systems and the services that support them.
 We had been aware for some time that the open access repository platforms and the content were not conforming to basic accessibility requirements, but the legislative deadline added urgency to our plans for change. The need for an accessibility statement for all our web-based systems encouraged us to look closely at, and find solutions for, the issues users of assistive technology encountered when accessing our systems and their content. In an open access environment – access needs to be open for all our users.
 We will describe our process and how we worked with colleagues in IT systems development and student services to create new methodologies and embed inclusive practices. Solutions included technical fixes, procedural changes and training and advocacy. We explore the challenges, what went well and what we have learnt, how we shared news about this work, and how we are committing to future digital content accessibility developments in research and scholarly communication support at the University of Kent.
A Quantitative Analysis of the Insecurity of Embedded Network Devices: Results of a Wide-Area Scan

description: We present a quantitative lower bound on the number of vulnerable embedded device on a global scale. Over the past year, we have systematically scanned large portions of the internet to monitor the presence of trivially vulnerable embedded devices. At the time of writing, we have identified over 540,000 publicly accessible embedded devices configured with factory default root passwords. This constitutes over 13% of all discovered embedded devices. These devices range from enterprise equipment such as firewalls and routers to consumer appliances such as VoIP adapters, cable and IPTV boxes to office equipment such as network printers and video conferencing units. Vulnerable devices were detected in 144 countries, across 17,427 unique private enterprise, ISP, government, educational, satellite provider as well as residential network environments. Preliminary results from our longitudinal study tracking over 102,000 vulnerable devices revealed that over 96% of such accessible devices remain vulnerable after a 4-month period. We believe the data presented in this paper provides a conservative lower bound on the actual population of vulnerable devices in the wild. By combining the observed vulnerability distributions and its potential root causes, we propose a set of mitigation strategies and hypothesize about its quantitative impact on reducing the global vulnerable embedded device population. Employing our strategy, we have partnered with Team Cymru to engage key organizations capable of significantly reducing the number of trivially vulnerable embedded devices currently on the internet. As an ongoing longitudinal study, we plan to gather data continuously over the next year in order to quantify the effectiveness of community's cumulative effort to mitigate this pervasive threat.

description: The mean values of a many-body Hamiltonian including a proton-neutron pairing term and matrix elements of one-, two- and four-body operators within a basis of particle number projected BCS states, are analytically expressed in terms of a single function Q(N) depending on the number of particles, $N$. The function Q(N) is calculated using a recursion in $N$ in which the shells and the BCS angles are kept the same for any step of iteration. An illustrative example is numerically considered in a restricted single particle space. Some specific features for the standard BCS, the projection after variation approach as well as for the variation after projection formalism, are pointed out.

description: Unconventional tight oil reservoirs have emerged as one of most important hydrocarbon resources due to the advanced horizontal-well drilling and multi-stage stimulation techniques. Optimizing well placement and fracture treatment design is critical to maximize well productivity and net present value (NPV) in such reservoirs. Using reservoir simulation to optimize performance of stimulation strategies is very computationally expensive due to extensive complex processes of hydraulic fracturing. With rapid development of unconventional reservoirs, the amount of data related to hydraulic fracturing process and well production is accumulating rapidly. Therefore, it is of practical interest for reservoir engineers to develop data-driven models to optimize the well performance in tight formations. In this study, a comprehensive data mining process is developed and successfully applied to evaluate the well performance in the Montney Formation, Western Canada. 6 features are identified as the most important variables by using the recursive feature elimination with cross validation (RFECV) method. Based on these features, four commonly used supervised learning approaches including random forest (RF), adaptive boosting (AdaBoost), support vector machine (SVM), and neural network (NN) are evaluated to predict the first-year oil production in the Montney Formation. It is found that the RF provides an accurate and robust production forecasting model in comparison with other three methods. Then, the applicability of the deep neural networks (DNNs) is evaluated to predict the early production in the Bakken tight Formation. An optimum DNN model is obtained by optimizing the hyperparameters of the DNN models. In addition, the recurrent neural networks (i.e., long short-term memory LSTMs) are applied to learn the pressure transient behavior in the stress-sensitive reservoirs. It is found that the developed LSTM models are capable of discovering relationships between the flow rate and pressure through data mining process without prior knowledge of physical models. Finally, a global optimization framework based on generalized differential evolution (GDE) algorithm is developed and successfully applied to optimize the production performance of multi-well pad in the Cardium tight oil formation. The optimization process integrates the available field data into the optimization framework to obtain a practical optimum scenario for the multi-well pad development.

description: Parasitic nematodes have a major impact on human and animal health and their control is threatened by the emergence of resistance to the anthelmintic drugs on which control depends. Although resistance to ivermectin is widespread in many livestock parasites, the genetic mechanisms remain elusive. In this thesis, a number of approaches are undertaken to investigate the genetics of ivermectin resistance in Haemonchus contortus, an important parasitic nematode research model. A transcriptomic comparison of the susceptible MHco3(ISE) and two ivermectin resistant strains, MHco4(WRS) and MHco10(CAVR), was undertaken to investigate if differences in gene expression revealed insights into ivermectin resistance mechanisms. Although this approach did not reveal clear ivermectin resistance gene candidates, the results have some important implications for RNAseq analysis in genetically diverse organisms. First, extremely high levels of genetic diversity in H. contortus had a major impact on RNAseq analysis and needed to be accounted for reliable identification of differentially expressed genes. Second, there were a remarkably large number of genes differentially expressed between the three H. contortus strains. In a novel genetic crossing approach, two independent serially backcrossed H. contortus populations were utilized in which ivermectin resistance loci had been introgressed into the MHco3(ISE) genome. Markers for six leading candidate ivermectin resistance genes from the literature were examined and none were found to show evidence of introgression in the backcross populations. A seventh marker, Hcms8a20 showed clear evidence of introgression and was later confirmed by collaborators using a whole genome sequencing approach to show its location in a 11.2 Mb introgressed region. A set of 25 in vivo or in vitro phenotyped ivermectin resistant H. contortus field populations were then used to investigate evidence of selection on the Hcms8a20 marker and four other loci distributed across the 11.2 Mb introgressed region. A deep amplicon sequencing approach revealed that, of the loci tested, only Hcms8a20 showed consistent evidence of purifying selection in the ivermectin resistant field populations. Overall, the results provide strong evidence that a major ivermectin resistance locus is located within a few megabases of the Hcms8a20 locus in many different ivermectin resistant H. contortus field populations.
Shaking table tests on the response of reinforced concrete frames with non-seismic detailing
Creators: name: Yavari, Soheil
Publisher: name: University of British Columbia
Year: 2011

description: Reinforced concrete frames constructed before the introduction of modern seismic codes have performed poorly during past earthquakes. Such frames have primarily been designed for gravity load effects, leading to light transverse reinforcement in the columns, unconfined beam-column joints, and generally a lack of seismic details required for ductile post-yield behaviour. It has been demonstrated in literature that light transverse reinforcement in a column may result in shear and axial failure. Furthermore, lack of confinement may cause shear failure at joints. However, interaction of vulnerable components and their contribution to the collapse behaviour of existing reinforced concrete frames is not well understood. This research project was initiated to provide a better understanding of the factors contributing to collapse of the frames with non-seismic detailing. In the experimental phase of this study, four 1:2.25 scale, two-bay-two-story specimens were designed with non-seismic details and tested on a shaking table. The target failure mode was intended to be damage leading to collapse that would enable examination of gravity load redistribution during the test. The tests provide unique benchmark data for both qualitative and quantitative assessment of the factors influencing the behaviour of reinforced concrete frames up to the point of collapse. Based on the results from the shaking table tests, this dissertation will evaluate the influence of axial load on shear and axial behaviour of non-ductile columns and the effects of unconfined joints on overall behaviour of a frame near the point of collapse. The analytical phase of the research included evaluation of existing models for predicting shear and axial failure of non-ductile columns and collapse of frames. The currently available models for shear and axial failure of non-ductile columns are mainly drift-based. The results of the current study suggest that these models should be refined using the column ends rotation demand. While results from comprehensive nonlinear models of the four specimens were compared with the test data, simplified models that can be easily employed in engineering practice for assessing existing frames were also evaluated. A refinement to provision from ASCE-41 on column effective stiffness was also proposed in this dissertation.

description: The purpose of this research was to investigate individual alpha peak frequency, event-related dynamics of brain oscillations, and the effect of neurofeedback training in the externally paced skill of ice hockey shooting. A review of literature and rationale for three stand-alone manuscripts are presented in chapter one. In chapter two, inter- and intra-individual variations in individual alpha peak frequency (IAPF) and ice hockey shooting performance were examined. No significant inter-individual variation between baseline IAPF and level of shooting performance or intra-individual pre- to post-shooting performance were found, suggesting that IAPF is a stable neurophysiological trait marker. In chapter three, event-related dynamics of brain oscillations in the externally paced skill of ice hockey shooting performance were explored. In contrast to research on closed skill sports, significant widespread ERS (or reduction of ERD) of theta, alpha, SMR and beta 1 bands was observed after the externally paced signal to shoot on net occurred. This finding is likely indicative of automaticity and reduced cognitive processing. Furthermore, widespread ERD occurred prior to the external cue, which is likely indicative of increased information processing. In chapter four, the effect of a sensorimotor rhythm (SMR) neurofeedback training (NFT) intervention on ice hockey shooting performance was investigated. The SMR-NFT participants demonstrated the ability to regulate SMR activity in the lab setting, but no significant changes in SMR power were observed during the actual ice hockey shooting performance. Ice hockey shooting performance was improved for all participants, yet the rate of improvement for the SMR-NFT group was significantly greater than the control. Finally, in chapter five overall findings and future recommendations are discussed.
A New Hypothesis for the Amount and Distribution of Dextral Displacement along the Fish Lake Valley–Northern Death Valley–Furnace Creek Fault Zone, California-Nevada

description: The Fish Lake Valley–northern Death Valley–Furnace Creek fault zone, a ~250 km long, predominantly right-lateral structure in California and Nevada, is a key element in tectonic reconstructions of the Death Valley area, Eastern California Shear Zone and Walker Lane, and central Basin and Range Province. Total displacement on the fault zone is contested, however, with estimates ranging from ~30 to ~63 km or more. Here we present a new synthesis of available constraints. Preextensional thrust faults, folds, and igneous rocks indicate that offset reaches a maximum of ~50 km. Neogene rocks constrain its partitioning over time. Most offset is interpreted as ≤ ~13–10 Ma, accruing at ~3–5 mm/yr in the middle of the fault zone and more slowly toward the tips. The offset markers imply ~68 ± 14 km of translation between the Cottonwood Mountains and Resting Spring–Nopah Range (~60 ± 14 km since ~15 Ma) through a combination of strike slip and crustal extension. This suggests that a previous interpretation of ~104 ± 7 km, based on the middle Miocene Eagle Mountain Formation, is an overestimate by ~50%. Our results also help to mitigate a discrepancy in the ~12–0 Ma strain budget for the Eastern California Shear Zone. Displacement has previously been estimated at ~100 ± 10 km and ~67 ± 6 km for the Basin and Range and Mojave portions of the shear zone, respectively. Our new estimate of ~74 ± 17 km for the Basin and Range is within the uncertainty of the Mojave estimate.

title: Vocality as / in Composition: solo and collaborative creation of new postopera works

description: As a contemporary opera singer-composer, director-producer, and filmmaker, my artistic research has yielded a new body of solo and collaborative postopera works in live and mediatised forms. My creative work and compositional methods are centred in an embodied vocal practice and the exploration of a multi-layered meaning-making process. My theoretical frame includes discourses surrounding contemporary music-theatre practices that deconstruct and challenge traditional Western operatic forms by favouring mediatised works, an abandonment of narrative drama, and an embrace of inventive, often experimental, performance methods. My practice has led me to investigate theoretical landscapes that include the work of musicologist and performance studies scholar Jelena Novak, theatre researcher Hans-Thies Lehmann, mid 20th-century French philosopher Maurice Merleau-Ponty, the Bulgarian-French philosopher, cultural theorist, and psychoanalyst, Julia Kristeva, and Italian philosopher Adriana Cavarero. In practical application, I am committed to the distribution and sharing of versioned forms of creative work, and my creative, theoretical, and practical means may be particularly relevant to other creator-producers.

description: In diesem Beitrag wird eine Studie vorgestellt, die im Kontext der kommunikationswissenschaftlichen Erinnerungsforschung erforscht, wie KZ-Gedenkstätten in verschiedenen europäischen Ländern die Plattform Instagram für die Erinnerungsarbeit nutzen. Über einen Zeitraum von zwei Monaten werden Instagrambeiträge im Rahmen einer quantitativen Inhaltsanalyse untersucht. Dabei wird herausgearbeitet, welche textlichen, audiovisuellen und interaktiven Inhalte publiziert werden. Drei Bereiche werden bei jedem Posting detailliert analysiert: das Thema des Beitrags, die Darstellungsform und mögliche Aufrufe zur Partizipation an die Instagramnutzer*innen. Dabei werden sieben Themenschwerpunkte herausgearbeitet. Postings, die das ehemalige Konzentrationslager, KZ-Häftlinge und historische Objekte darstellen, werden einem ‚historischen Kontext‘ zugeordnet: Hier werden Orte, Menschen und Exponate aus der NS-Zeit vorgestellt. Beiträge über den Besuch einer KZ-Gedenkstätte, die heutige Arbeit in der KZ-Gedenkstätte sowie Zeitzeugenschaft haben einen stärkeren Gegenwartsbezug: Diese Postings sind als Bemühen der Gedenkstätten zu verstehen, historisches Wissen im Hier und Jetzt zu vermitteln. Die Ergebnisse dokumentieren den aktuellen Stand der Onlinekommunikation von Gedenkstätten. Es wird gezeigt, inwieweit die Instagramauftritte zur Veränderung der dortigen Erinnerungsarbeit beitragen.
