description: We present a study of the second-order nonlinear optical properties of metal-based metamaterials. A hydrodynamic model for electronic response is used, in which nonlinear surface contributions are expressed in terms of the bulk polarization. The model is in good agreement with published experimental results, and clarifies the mechanisms contributing to the nonlinear response. In particular, we show that the reported enhancement of second-harmonic in split-ring resonator based media is driven by the electric rather than the magnetic properties of the structure.

description: Motivated by the second author's construction of a classifying space for the group of pure symmetric automorphisms of a free product, we introduce and study a family of topological operads, the operads of based cacti, defined for every pointed topological space $(Y,\bullet)$. These operads also admit linear versions, which are defined for every augmented graded cocommutative coalgebra $C$. We show that the homology of the topological operad of based $Y$-cacti is the linear operad of based $H_*(Y)$-cacti. In addition, we show that for every coalgebra $C$ the operad of based $C$-cacti is Koszul. To prove the latter result, we use the criterion of Koszulness for operads due to the first author, utilising the notion of a filtered distributive law between two quadratic operads. We also present a new proof of that criterion which works over the ground field of arbitrary characteristic.

description: Incoherent dedispersion is a computationally intensive problem that appears frequently in pulsar and transient astronomy. For current and future transient pipelines, dedispersion can dominate the total execution time, meaning its computational speed acts as a constraint on the quality and quantity of science results. It is thus critical that the algorithm be able to take advantage of trends in commodity computing hardware. With this goal in mind, we present analysis of the 'direct', 'tree' and 'sub-band' dedispersion algorithms with respect to their potential for efficient execution on modern graphics processing units (GPUs). We find all three to be excellent candidates, and proceed to describe implementations in C for CUDA using insight gained from the analysis. Using recent CPU and GPU hardware, the transition to the GPU provides a speed-up of 9x for the direct algorithm when compared to an optimised quad-core CPU code. For realistic recent survey parameters, these speeds are high enough that further optimisation is unnecessary to achieve real-time processing. Where further speed-ups are desirable, we find that the tree and sub-band algorithms are able to provide 3-7x better performance at the cost of certain smearing, memory consumption and development time trade-offs. We finish with a discussion of the implications of these results for future transient surveys. Our GPU dedispersion code is publicly available as a C library at: http://dedisp.googlecode.com/

description: Our research explores the use of mobile video chat in public spaces by people participating in parallel experiences, where both a local and remote person are doing the same activity together at the same time. We prototyped a wearable video chat experience and had pairs of friends and family members participate in 'shared geocaching' over distance. Our results show that video streaming works best for navigation tasks but is more challenging to use for fine-grained searching tasks. Video streaming also creates a very intimate experience with a remote partner, but this can lead to distraction from the 'real world' and even safety concerns. Overall, privacy concerns with streaming from a public space were not typically an issue; however, people tended to rely on assumptions of what were acceptable. The implications are that designers should consider appropriate feedback, user disembodiment, and asymmetry when designing for parallel experiences.

description: We introduce discrete multivortex solitons in a ring of nonlinear oscillators coupled to a central site. Regular clusters of discrete vortices appear as a result of mode collisions and we show that their stability is determined by global symmetries rather than the stability of constituent vortices. Stable multivortex solitons support complex vortex dynamics including charge flipping and spiraling.

Dark Patterns in Proxemic Interactions: A Critical Perspective

Publisher: name: ACM

description: Proxemics theory explains peoples' use of interpersonal distances to mediate their social interactions with others. Within Ubicomp, proxemic interaction researchers argue that people have a similar social understanding of their spatial relations with nearby digital devices, which can be exploited to better facilitate seamless and natural interactions. To do so, both people and devices are tracked to determine their spatial relationships. While interest in proxemic interactions has increased over the last few years, it also has a dark side: knowledge of proxemics may (and likely will) be easily exploited to the detriment of the user. In this paper, we offer a critical perspective on proxemic interactions in the form of dark patterns: ways proxemic interactions can be misused. We discuss a series of these patterns and describe how they apply to these types of interactions. In addition, we identify several root problems that underlie these patterns and discuss potential solutions that could lower their harmfulness.
High electron gain from single walled carbon nanotubes stimulated by interaction with an electron beam
Creators: name: Michan, Mario
Publisher: name: University of British Columbia
Year: 2010

description: Carbon nanotubes, hollow cylindrical structures made of carbon atoms with diameters in the order of a few nanometres, are attractive candidates for electron emission applications. A detailed characterization of the phenomenon so-called electron-stimulated field-emission from carbon nanotubes is presented in this thesis. An electron beam hitting the tip of a nanotube biased near the threshold of field-emission can stimulate the emission of a large number of electrons from the nanotube tip. The result of this interaction is that high electron gains can be obtained with very small stimulating electron beam currents. Electron gains of up to 2300 were recorded. This is important as this effect could form the basis of several vacuum nanoelectronic devices. Possible direct and indirect electron-nanotube interaction mechanisms responsible for this high gain are discussed and substantiated through simulations. The design and assembly of an ultra high vacuum apparatus for more controlled future experiments is also presented.

description: Intricate networks of interactions between organisms and their environment form the ecosystems that sustain life on earth. Our planet is changing at an alarming rate. This causes disruptions to ecosystems and a major loss of biodiversity. Understanding species interaction networks and understanding and predicting invasive species behavior is a growing imperative for next-generation biodiversity monitoring. The current research uses rule mining on a large species interaction network to detect interesting patterns that can help understand species interaction networks. Link prediction is used as a tool to understand and predict invasive species behavior. Domain expert knowledge was used to evaluate the interestingness of these patterns. Results for rule mining show that the found patterns do well at explaining the interactions in the training data, with an average quality of 0.61 and 0.52 over the top-5 and top-100 patterns, respectively. The patterns have low generalizability, with an average precision of 0.13 and 0.12 over the top-5 and top-100 patterns, respectively. This indicates that our model is overfitting to the training data. The domain experts judged the interestingness of the patterns with with an overall score of 3.06 out of 5. A slight inter-rater agreement is found with an $\alpha_K$ of 0.105. Results for link prediction show that in 10\% of the cases, our model correctly predicts the answer to a query. Rule mining and link prediction are promising tools for the analysis of species interactions networks and invasive species behavior. Further research is needed to enhance model performance.
An exploration of early-stage professional identity development: The being and becoming of first-year speech and language therapy students
Creators: name: Tucker, Kate
Publisher: name: Cardiff Metropolitan University
Year: 2023
Subjects: Speech pathology

description: The main aim of this study was to understand the experience of professional identity development in first-year SLT students. This was supported by two objectives, to understand students’ perceptions of the nature of SLT professional identity and to understand influences on their process of professional identity development. The study had a focus on first-year students, as early experiences during training are pivotal in shaping professional identity. This interpretivist study employed hermeneutic phenomenological methodology to explore the lived experience of 11, first-year SLT students. Individual semi-structured interviews were carried out twice, at the start and end of the academic year. Data were analysed via an iterative process of coding, interpretation, and theme development. The participants were seeking a professional identity which aligned with their own qualities and values. Characteristics perceived central to SLT identity were compassion, connection, equality, positivity, praxis, and being professional. Professional identity development was influenced by the approach of the practice educator; opportunities for autonomy; interprofessional encounters; and client interactions. The findings underline the importance of meaningful engagement in early, authentic clinical experiences for professional identity development. Practice educators are the gatekeepers to these experiences. SLT professional identity development was a socially co-constructed, individualised process of negotiation between expectations and reality, and integration of personal and professional identities. Supporting students in reflexively engaging in this process cultivates a clinical practice which has integrity and is motivated by values.

description: We present PhoneEar, a new approach that enables mobile devices to understand the broadcasted audio and sounds that we hear every day using existing infrastructure. PhoneEar audio streams are embedded with sound-encoded data using nearly inaudible high frequencies. Mobile devices then listen for messages in the sounds around us, taking actions to ensure we don't miss any important info. In this paper, we detail our implementation of PhoneEar, describe a study demonstrating that mobile devices can effectively receive sound-based data, and describe the results of a user study that shows that embedding data in sounds is not detrimental to sound quality. We also exemplify the space of new interactions, through four PhoneEar-enabled applications. Finally, we discuss the challenges to deploying apps that can hear and react to data in the sounds around us.

description: We discuss the creation of quantum discord between two two-level atoms trapped in an optical cavity in a noisy environment. It is shown that nonzero steady-state quantum discord between atoms can be obtained when the white-noise field is separately imposed on atoms or cavity mode, while the steady-state quantum discord reaches zero if both cavity mode and atoms are driven simultaneously by white-noise fields. In particular, we demonstrate that white-noise field in different cases can play a variously constructive role in the generation of quantum discord.

description: There is a well-established culture of early prototyping when designing digital interactive systems, such as paper prototyping and wireframe methods. The culture of designing physical objects is somewhat different: early explorations of form is still prototyped via 2D sketches or renderings, but - mostly because of the construction effort involved - prototyping of actual physical objects is deferred to later stages. A problem occurs when designing mixed physical-digital systems, such as tangible user interfaces (TUIs) on interactive surfaces: the high degree of interactivity means that early prototyping is vital, yet there is no viable process for prototyping both the physical and digital aspects simultaneously on a low-fidelity (low-fi) level. Our solution is Paperbox, a toolkit for exploring design ideas for tangible interaction on interactive surfaces. It supports the early exploration of different form factors and immediately provides digital interactivity for the low-fidelity TUI prototypes built with it. We observed our toolkit in use in various settings: as a brainstorming tool by junior designers; in the development of a consumer electronics product in a large industrial company by senior designers; and in a usability study comparing the effect of different levels of fidelity on the outcome. The lessons learnt will enable others to replicate and extend our approach.

description: In hydrodynamicalmodeling of heavy-ion collisions the initial state spatial anisotropies translate into momentum anisotropies of the final state particle distributions. Thus, understanding the origin of the initial anisotropies and quantifying their uncertainties is important for the extraction of specific QCD matter properties, such as viscosity, from the experimental data. In this work we study the wounded nucleon approach in the Monte Carlo Glauber model framework, focusing especially on the uncertainties which arise from the modeling of the nucleon-nucleon interactions between the colliding nucleon pairs and nucleon-nucleon correlations inside the colliding nuclei. We compare the black disk model and a probabilistic profile function approach for the inelastic nucleon-nucleon interactions, and study the effects of initial state correlations using state-of-theart modeling of these.

description: Microseismic visualization systems present complex 3D data of small seismic events within oil reservoirs to allow experts to explore and interact with that data. Yet existing systems suffer several problems: 3D spatial navigation and orientation is difficult, and selecting 3D data is challenging due to the problems of occlusion and lack of depth perception. Our work mitigates these problems by applying both proxemic interactions and a spatial input device to simplify how experts navigate through the visualization, and a painting metaphor to simplify how they select that information.

It is shown that these symmetries are suitably handled with quaternions and octonions in order to obtain their generators, commutation rules and symmetry properties. Accordingly, Casimir operators for SU(2)and SU(3) flavor symmetries are also constructed for the proper testing of these symmetries in terms of quaternions and octonions.

description: Current touch-based interactive surfaces rely heavily on a trial-and-error approach for guiding users through the interaction process. In contrast, the legacy WIMP (Windows, Icons, Menus, Pointer) paradigm employs various methods to provide user assistance. A commonly used strategy is the use of mouse hovering. This research explores how this strategy can be adapted and expanded to user interaction with interactive surfaces to provide user assistance as well as to help address common surface interaction issues, such as precisions. Design dimensions and considerations are discussed, and potential hover interaction techniques are proposed. These techniques emphasize the use of animation to facilitate user engagement and improve the overall user experience.

description: Whilst theories of defect assisted ionic conductivity have been developed for crystalline inorganic materials, organic ionic plastic crystals (OIPCs) offer a unique opportunity to test these theories in soft materials. Nanoparticles have been shown to alter local matrix mobility dependent on the wetting of the particles by the matrix to increase conductivity in polymeric materials [Weston]; however, the mechanism of this enhancement is the subject of debate. The combination of inert nanosized particles in crystalline inorganic conductors has also been shown to significantly enhance ionic conductivity and have been often linked to a space charge mechanism'. In this thesis, the effect of ceramic nanoparticles such as Ti02, Ali03 and Si02 on the conductivity and structure of pure OIPCs, lithium doped OIPCs and rotator phase material have been investigated over a wide temperature range. The work also included the assessment of the effect of Si02 nanoparticles of varying surface area and determining the effect of surface-functionalised nanoparticles […]
Collaborative sensemaking on a digital tabletop and personal tablets: prioritization, comparisons, and tableaux

Year: 2013

description: We describe an investigation of the support that three different display configurations provided for a collaborative sensemaking task: a digital table; personal tablets; and both the tabletop and personal tablets. Mixed-methods analyses revealed that the presence of a digital tabletop display led to improved sensemaking performance, and identified activities that were supported by the shared workspace. The digital tabletop supported a group's ability to prioritize information, to make comparisons between task data, and to form and critique the group's working hypothesis. Analyses of group performance revealed a positive correlation with equity of member participation using the shared digital table, and a negative correlation of equity of member participation using personal tablets. Implications for the support of sensemaking groups, and the use of equity of member participation as a predictive measure of their performance are discussed.
A He3 driven instability near the fully convective boundary

description: We report on the discovery of an instability in low mass stars just above the threshold ($\sim 0.35 \textrm{M}_{\odot}$) where they are expected to be fully convective on the main sequence. Non-equilibrium He3 burning creates a convective core, which is separated from a deep convective envelope by a small radiative zone. The steady increase in central He3 causes the core to grow until it touches the surface convection zone, which triggers fully convective episodes in what we call the "convective kissing instability". These episodes lower the central abundance and cause the star to return to a state in which is has a separate convective core and envelope. These periodic events eventually cease when the He3 abundance throughout the star is sufficiently high that the star is fully convective, and remains so for the rest of its main sequence lifetime. The episodes correspond to few percent changes in radius and luminosity, over Myr to Gyr timescales. We discuss the physics of the instability, as well as prospects for detecting its signatures in open clusters and wide binaries. Secondary stars in cataclysmic variables (CVs) will pass through this mass range, and this instability could be related to the observed paucity of such systems for periods between two and three hours. We demonstrate that the instability can be generated for CV secondaries with mass-loss rates of interest for such systems, and discuss potential implications.

description: RNA interference (RNAi) is an endogenous cellular process in which small double-stranded RNAs lead to the destruction of mRNAs with complementary nucleoside sequence. With the production of RNAi libraries, large-scale RNAi screening in human cells can be conducted to identify unknown genes involved in a biological pathway. One challenge researchers face is how to deal with the multiple testing issue and the related false positive rate (FDR) and false negative rate (FNR). This paper proposes a Bayesian hierarchical measurement error model for the analysis of data from a two-channel RNAi high-throughput experiment with replicates, in which both the activity of a particular biological pathway and cell viability are monitored and the goal is to identify short hair-pin RNAs (shRNAs) that affect the pathway activity without affecting cell activity. Simulation studies demonstrate the flexibility and robustness of the Bayesian method and the benefits of having replicates in the experiment. This method is illustrated through analyzing the data from a RNAi high-throughput screening that searches for cellular factors affecting HCV replication without affecting cell viability; comparisons of the results from this HCV study and some of those reported in the literature are included.

Authentication and key management in heterogeneous wireless networks
Creators: name: Al Shidhani, Ali
Publisher: name: University of British Columbia
Year: 2010

description: Interworking wireless technologies such as the Wireless Local Area Network (WLAN), the Worldwide Interoperability for Microwave Access (WiMAX) and mobile communication systems conforming to the Third-Generation Partnership Project (3GPP) standards forms a heterogeneous wireless network. Designing secure and efficient authentication protocols to enable fast connections to the heterogeneous network is challenging. Existing standard authentication protocols mandate users to perform authentication with authentication servers located in the 3GPP Home Network (3GHN). This approach is highly inefficient. Other research work suggested performance-enhanced protocols but introduced other problems such as degrading system security. This thesis presents the designs of authentication protocols that balance security and performance by applying minor modifications to the standard authentication protocols. The proposed protocols attempt to minimize the communications between users and the 3GHN during authentication. Several protocols are proposed in this thesis to address inefficient authentications in the heterogeneous network. Firstly, in 3GPP-WLAN interworking, we propose fast authentication protocols that expedite authenticating stationary and mobile users by completing authentications locally without contacting the 3GHN. The proposed protocols outperform standard protocols and support essential security requirements such as the adoption of a secure key management scheme. Secondly, in 3GPP-WiMAX interworking, we design two handover (HO) protocols that piggyback authentication queries on HO control messages to avoid initiating a separate authentication session after performing a HO. Our proposed protocols prove to accelerate the HO procedure and conserve users’ computing resources. Important security qualities such as the provision of forward and backward secrecy are also maintained by our proposed protocols. Thirdly, we design six re-authentication protocols to improve HOs between 3GPP, WiMAX and WLAN systems. The proposed protocols capitalize on the execution of an initial extensive authentication protocol to enable successive expedited HO re-authentications. Remarkable performance improvements are achieved when adopting our proposed protocols compared to standard protocols. Lastly, we propose protocols to enable efficient and secure multi-hop accesses to the heterogeneous network. A secure multi-hop authentication protocol and a secure multi-hop Mobile IP registration scheme are designed. Our scheme surpasses competitive schemes in terms of registration delay and power consumption while resisting against security attacks existing in the multi-hop network.

description: We perform a study of the LHC discovery reach on a heavy gluon (G*) and heavy fermions (top and bottom excitations), coming from a new composite sector. We find that heavy fermion resonances have a great impact on the composite gluon phenomenology. If the composite gluon is heavier than composite fermions, as flavor observables seem to suggest, the search in the channel where G* decays into a heavy fermion plus its Standard Model partner is very promising, with the possibility for both the G* and heavy fermions to be discovered at the early stage of the LHC. The channel offers also the possibility to extract important information on model parameters, such as the top degree of compositeness.

description: Gestures are a ubiquitous part of human communication over tables, but when tables are distributed, gestures become difficult to capture and represent. There are several problems: extracting arm images from video, representing the height of the gesture, and making the arm embodiment visible and understandable at the remote table. Current solutions to these problems are often expensive, complex to use, and difficult to set up. We have developed a new toolkit - KinectArms - that quickly and easily captures and displays arm embodiments. KinectArms uses a depth camera to segment the video and determine gesture height, and provides several visual effects for representing arms, showing gesture height, and enhancing visibility. KinectArms lets designers add rich arm embodiments to their systems without undue cost or development effort, greatly improving the expressiveness and usability of distributed tabletop groupware.

description: In the early spring of 2007 I was approached by the then directorial MFA candidate David Savoy with a request to design the scenery for his thesis production A Dybbuk by S. Ansky in an adaptation by Tony Kushner, and I accepted his offer. The other members of the design team were Ariel Rivera for Costume Design (a BFA Design and Production graduate), Ian Giles for Lighting Design (a BFA Design and Production graduate) and Jason Ho for Sound Design (a BFA Design and Production student). The original songs and music were composed by Patrick Pennefather and performed by the Creaking Planks. The production was Stage Managed by the BFA Design and Production student Cassandra Tattrie. It ran from March 27 to April 5, 2008 at the Frederic Wood Theatre. The challenges of designing the scenery for this production lay in accommodating a cast of eighteen actors that played over thirty different characters, as well as a live klezmer band that performed onstage throughout the play. Our idea was to create stationary scenery that would present the necessary imagery for all the environments of the play without having to perform large scene changes. We were also determined not to have stage hands visible to the audience, which meant that all the scene changes and the traffic of properties was to be managed by the actors themselves. The locations where the action of the play took place were the old synagogue in Brinnitz, a Brinnitz square outside of Sender’s home, a train station near the Jewish Ghetto in Miropol and Rabbi Azriel’s study in Miropol. My goal was to create an overall environment that would provide an emotional and cultural subtext for the play and create the basic structure sufficient to suggest all of these locations in such a way that they could be identified and interpreted both by the audience members familiar with the Eastern European Jewish culture and by those new to it.

description: We present an analysis of Spitzer IRAC (3.6--8um) and MIPS (24um) imaging of members of the 16(+10/-5)Myr old open cluster NGC 1960 (M36). Models of terrestrial planet formation indicate that rocky planets are likely to achieve their final masses at around 10-30Myr, and thus this cluster is at an interesting epoch for planet formation. We find 21 B-F5 type stars and 14 F6-K9 type stars which have 24um excess emission, and thus determine that >30% of B-F5 type stars and >23% of F6-K9 type stars in this cluster have 24um excess emission. These excess frequencies are similar to those observed in other clusters of similar age. Three early type stars have excesses at near-infrared wavelengths. Analysis of their SEDs confirms that these are true debris discs and not remnant primordial or transitional discs. None of the 61 sun-like stars have confirmed near-infrared excess, and we can place a limit on the frequency of 8um excess emission around sun-like stars of <7%. All of the detected excesses are consistent with emission from debris discs and are not primordial.

description: In the era of synoptic surveys, the number of known gravitationally lensed quasars is set to increase by over an order of magnitude. These new discoveries will enable a move from single-quasar studies to investigations of statistical samples, presenting new opportunities to test theoretical models for the structure of quasar accretion discs and broad emission line regions (BELRs). As one crucial step in preparing for this influx of new lensed systems, a large-scale exploration of microlensing convergence-shear parameter space is warranted, requiring the computation of O(10^5) high resolution magnification maps. Based on properties of known lensed quasars, and expectations from accretion disc/BELR modelling, we identify regions of convergence-shear parameter space, map sizes, smooth matter fractions, and pixel resolutions that should be covered. We describe how the computationally time-consuming task of producing ~290000 magnification maps with sufficient resolution (10000^2 pixel/map) to probe scales from the inner edge of the accretion disc to the BELR can be achieved in ~400 days on a 100 teraflop/s high performance computing facility, where the processing performance is achieved with graphics processing units. We illustrate a use-case for the parameter survey by investigating the effects of varying the lens macro-model on accretion disc constraints in the lensed quasar Q2237+0305. We find that although all constraints are consistent within their current error bars, models with more densely packed microlenses tend to predict shallower accretion disc radial temperature profiles. With a large parameter survey such as the one described here, such systematics on microlensing measurements could be fully explored.

Effects of consistent and inconsistent isobar coupling in the nuclear medium

description: We investigate effects of consistent (conserving the number of degrees of freedom) and inconsistent pion-nucleon-isobar couplings on the isobar propagator in vacuum and in nuclear medium. Using the consistent coupling in conjunction with a convenient basis leads to significant simplification of the isobar vacuum and in-medium self energy and dressed propagator compared to the case of inconsistent interaction. The higher-derivative nature of the consistent interaction requires a suitable compensation by an additional form-factor term or adjustment in the used cut-off values. This modification is straightforward to perform and assures that the physical observables connected to the spin-3/2 sector in vacuum and nuclear medium acquire values indistinguishable from the ones obtained by using an inconsistent coupling.

description: Wet granulation is a widely used technique to produce particle aggregates in many industries including detergent, pharmaceutical, agricultural product, food, and specialty chemicals. In wet granulation, a liquid binder is used to agglomerate fine particles. In high-shear wet granulation, breakage and attrition of aggregates play an important role. However, the breakage and attrition processes are the least understood among all rate processes of wet granulation. In the present study, to better understand the breakage and attrition phenomena, experiments and simulations were performed to study the effect of formulation properties and operating parameters on the breakage behaviour of preformed granules.

description: The impacts of clones on software maintenance is a long-lived debate on whether clones are beneficial or not. Some researchers argue that clones lead to additional changes during the maintenance phase and thus increase the overall maintenance effort. Moreover, they note that inconsistent changes to clones may introduce faults during evolution. On the other hand, other researchers argue that cloned code exhibits more stability than non-cloned code. Studies resulting in such contradictory outcomes may be a consequence of using different methodologies, using different clone detection tools, defining different impact assessment metrics, and evaluating different subject systems. In order to understand the conflicting results from the studies, we plan to conduct a comprehensive empirical study using a common framework incorporating nine existing methods that yielded mostly contradictory findings. Our research strategy involves implementing each of these methods using four clone detection tools and evaluating the methods on more than fifteen subject systems of different languages and of a diverse nature. We believe that our study will help eliminate tool and study biases to resolve conflicts regarding the impacts of clones on software maintenance.

description: We consider the application of requirements engineering principles and techniques to the elicitation, capture, and representation of the output of the user experience design process. A stimulus-perception-response model is used to motivate experience requirements, defined as descriptions of user experiences that must be met (functional experiences) or are satisfaction goals (non-functional experiences). We identify potential benefits and look at experience requirements in video games.

description: Selbstbestimmtes Lernen mit Onlinekursen findet zunehmend mehr Akzeptanz in unserer Gesellschaft. Lernende können mithilfe von Onlinekursen selbst festlegen, was sie wann lernen und Kurse können durch vielfältige Adaptionen an den Lernfortschritt der Nutzer angepasst und individualisiert werden. Auf der einen Seite ist eine große Zielgruppe für diese Lernangebote vorhanden. Auf der anderen Seite sind die Erstellung von Onlinekursen, ihre Bereitstellung, Wartung und Betreuung kostenintensiv, wodurch hochwertige Angebote häufig kostenpflichtig angeboten werden müssen, um als Anbieter zumindest kostenneutral agieren zu können. In diesem Beitrag erörtern und diskutieren wir ein offenes, nachhaltiges datengetriebenes zweiseitiges Geschäftsmodell zur Verwertung geprüfter Onlinekurse und deren kostenfreie Bereitstellung für jeden Lernenden. Kern des Geschäftsmodells ist die Nutzung der dabei entstehenden Verhaltensdaten, die daraus mögliche Ableitung von Persönlichkeitsmerkmalen und Interessen und deren Nutzung im kommerziellen Kontext. Dies ist eine bei der Websuche bereits weitläufig akzeptierte Methode, welche nun auf den Lernkontext übertragen wird. Welche Möglichkeiten, Herausforderungen, aber auch Barrieren überwunden werden müssen, damit das Geschäftsmodell nachhaltig und ethisch vertretbar funktioniert, werden zwei unabhängige, jedoch synergetisch verbundene Geschäftsmodelle vorgestellt und diskutiert. Zusätzlich wurde die Akzeptanz und Erwartung der Zielgruppe für das vorgestellte Geschäftsmodell untersucht, um notwendige Kernressourcen für die Praxis abzuleiten. Die Ergebnisse der Untersuchung zeigen, dass das Geschäftsmodell von den Nutzer*innen grundlegend akzeptiert wird. 10 % der Befragten würden es bevorzugen, mit virtuellen Assistenten – anstelle mit Tutor*innen zu lernen. Zudem ist der Großteil der Nutzer*innen sich nicht darüber bewusst, dass Persönlichkeitsmerkmale anhand des Nutzerverhaltens abgeleitet werden können.
