Therapists’ perceptions of the childhood experiences of male sex offenders
Creators: name: Pedersen, Kurt A.
Publisher: name: University of British Columbia
Year: 2009

description: There are indications that sex offending behaviors begin to develop in childhood, and are influenced by the experiences sex offenders have as children. Traumatic sexual abuse is one type of experience known to contribute to sex offending behavior, but non-traumatic experiences may also influence this behavior. This study was conducted to determine what childhood experiences therapists perceived as impacting the development of sex offending behavior in males. This qualitative study employed purposeful sampling techniques. A sampling frame of 18 therapists in private practice, who were known to work with male sex offenders, were sent a letter describing the study and asking for their participation. Of these 5 male therapists responded and were interviewed. A semi-structured interview guide was employed; all interviews were recorded and transcribed. Each of the therapists taking part in this study had at least 2 years experience working with sex offenders, and 3 of them had 7 or more years experience. Each of the therapists interviewed had attained at least a Masters degree and two had Ph.D.'s in psychology. The clients seen by these therapists because of their sex offending behavior ranged in age from 4 to 80 years. Four of the five therapists also provided services to male survivors of sexual abuse. Qualitative methods of content analysis were employed. Three categories and one over-riding theme described the data. The three categories support an ecological approach. Therapists identified factors at an individual, family environmental, and cultural level of experience which they perceive as influencing the development of sex offending behavior. Therapists described this development as an evolutionary process and believed that childhood experiences influence that process. An ecological model describing this process is presented. A number of limitations are discussed which preclude the possibility of forming firm conclusions. However, this data corroborates other studies which suggest that childhood experiences influence the development of sex offending behavior, and that this behavior begins to manifest itself in childhood. Implications arising from this study support the notion that further research is needed in this area. This study also argues that identifying childhood experiences which influence the development of male sex offending behaviors can lead to more effective and proactive interventions. Changing sex offending patterns of behavior in male children may be a much easier task than treating those behaviors when they have become entrenched in adults.

description: Based on the assertion that the cosmological constant problem is essentially a quantum gravity problem, the framework which addresses the cosmological constant problem should also bear a picture for the ``quantum space-time''. In this talk in an attempt to address the cosmological constant problem I suggest to start with noncommutative fuzzy spheres as the toy model for the quantum space-time. In this setting, we show that the cosmological constant problem may be resolved due to the noncommutativity and ``fuzziness'' of the space and the fact that the smallest volume which could be measured in the a quantum space-time is much larger than the naively expected Planckian size. This talk is based on Ref.[1] which has appeared on the arXiv as hep-th/0605110.

description: In this paper, we take a control-theoretic approach to answering some standard questions in statistical mechanics. A central problem is the relation between systems which appear macroscopically dissipative but are microscopically lossless. We show that a linear macroscopic system is dissipative if and only if it can be approximated by a linear lossless microscopic system, over arbitrarily long time intervals. As a by-product, we obtain mechanisms explaining Johnson-Nyquist noise as initial uncertainty in the lossless state as well as measurement back action and a trade off between process and measurement noise.

description: $β$-cells are biologically essential for humans and other vertebrates. Because their functionality arises from cell-cell interactions, they are also a model system for collective organization among cells. There are currently two contradictory pictures of this organization: the hub-cell idea pointing at leaders who coordinate the others, and the electrophysiological theory describing all cells as equal. We use new data and computational modeling to reconcile these pictures. We find via a network representation of interacting $β$-cells that leaders emerge naturally (confirming the hub-cell idea), yet all cells can take the hub role following a perturbation (in line with electrophysiology). A useful network representation of complex systems is via pairwise cross-correlations between a system's constituents. Recently, attempts have been made at representing pancreatic $β$-cells collectives as networks, giving birth to the concept of hub cells, which contradicts established electrophysiological theory. Here, we reconcile the hub-cell idea with electrophysiology using empirical and computational methods. While the former reveals the functional importance of hubs, the latter show that hubs are an emergent property of communication among identical peers. Thus, individual cells are perfectly capable of playing the hub role, but in line with electrophysiology, they do not have to be genetically predisposed to do so. This points to an ultra-robust architecture of $β$-cell collectives and underpins some of their vital features.

description: Within this PhD Thesis a methodology is developed and evaluated, able to improve real-time flood forecasting in catchments located at mid-latitudes, using satellite rainfall data products. Since the current satellite instruments cannot measure light rain (<1 mm/h) or distinguish rainfall from snowfall, the accumulated rainfall is underestimated compared to the actual rainfall. For this reason, the satellite rainfall estimates are corrected and calibrated using measurements from ground stations. If no post-processing takes place, then the runoff will be underestimated, which in turn renders the satellite measurements inappropriate for flood forecasting away from the tropics. For this reason, a new methodology is developed, where (a) all existing satellite measurements are validated, (b) unprocessed satellite measurements undergo a real-time correction using ground measurements and (c) all products, including the initial and corrected sets are fed in a statistical rainfall – runoff model. The model is first calibrated using historical records of runoff measurements taken in two separate locations, Edirne and Delta and then it uses aggregated rainfall to estimate runoff in two predefined outlets. This procedure was carried out using a series of databases and software models, programmed for this Thesis. The databases are used to store and retrieve satellite and ground measurements. Each data set uses its own dedicated database, which can interact with the software models using the Open Modeling Interface (OpenMI) protocol. The protocol is also used to establish connections between the software models themselves, thus enabling complex simulations using simpler component

description: In this paper we define complex equivariant K-theory for actions of Lie groupoids using finite-dimensional vector bundles. For a Bredon-compatible Lie groupoid, this defines a periodic cohomology theory on the category of finite equivariant CW-complexes. We also establish an analogue of the completion theorem of Atiyah and Segal. Some examples are discussed.

description: The XMM-RM project was designed to provide X-ray coverage of the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) field. 41 XMM-Newton exposures, placed surrounding the Chandra AEGIS field, were taken, covering an area of 6.13 deg^2 and reaching a nominal exposure depth of ~15 ks. We present an X-ray catalog of 3553 sources detected in these data, using a PSF-fitting algorithm and a sample selection threshold that produces a ~5% fraction of spurious sources. In addition to the PSF-fitting likelihood, we calculate a second source reliability measure based on Poisson theory using source and background counts within an aperture. Using the Poissonian likelihood, we select a sub-sample with a high purity and find that it has similar number count profiles to previous X-ray surveys. The Bayesian method "NWAY" was employed to identify counterparts of the X-ray sources from the optical Legacy and the IR unWISE catalogs, using a 2-dimensional unWISE magnitude-color prior created from optical/IR counterparts of Chandra X-ray sources. A significant number of the optical/IR counterparts correspond to sources with low detection likelihoods, proving the value of retaining the low-likelihood detections in the catalog. 932 of the XMM-RM sources are covered by SDSS spectroscopic observations. 89% of them are classified as AGN, and 71% of these AGN are in the SDSS-RM quasar catalog. Among the SDSS-RM quasars, 80% are detectable at the depth of the XMM observations.

description: The current literature on sandpile models mainly deals with the abelian sandpile model (ASM) and its variants. We treat a less known - but equally interesting - model, namely Zhang's sandpile. This model differs in two aspects from the ASM. First, additions are not discrete, but random amounts with a uniform distribution on an interval $[a,b]$. Second, if a site topples - which happens if the amount at that site is larger than a threshold value $E_c$ (which is a model parameter), then it divides its entire content in equal amounts among its neighbors. Zhang conjectured that in the infinite volume limit, this model tends to behave like the ASM in the sense that the stationary measure for the system in large volumes tends to be peaked narrowly around a finite set. This belief is supported by simulations, but so far not by analytical investigations. We study the stationary distribution of this model in one dimension, for several values of $a$ and $b$. When there is only one site, exact computations are possible. Our main result concerns the limit as the number of sites tends to infinity, in the one-dimensional case. We find that the stationary distribution, in the case $a \geq E_c/2$, indeed tends to that of the ASM (up to a scaling factor), in agreement with Zhang's conjecture. For the case $a=0$, $b=1$ we provide strong evidence that the stationary expectation tends to $\sqrt{1/2}$.

description: We investigate inelastic microwave photon scattering by a transmon qubit embedded in a high-impedance circuit. The transmon undergoes a charge-localization (Schmid) transition upon the impedance reaching the critical value. Due to the unique transmon level structure, the fluorescence spectrum carries a signature of the transition point. At higher circuit impedance, quasielastic photon scattering may account for the main part of the inelastic scattering cross-section; we find its dependence on the qubit and circuit parameters.

alpha-nucleus potentials, alpha-decay half-lives, and shell closures for superheavy nuclei
Creators: name: Mohr, Peter
Publisher: name: arXiv
Year: 2006
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Systematic alpha-nucleus folding potentials are used to analyze alpha-decay half-lives of superheavy nuclei. Preformation factors of about several per cent are found for all nuclei under study. The systematic behavior of the preformation factors and the volume integrals of the potentials allows to predict alpha-decay energies and half-lives for unknown nuclei. Shell closures can be determined from measured alpha-decay energies using the discontinuity of the volume integral at shell closures. For the first time a double shell closure is predicted for Z_magic = 132, N_magic = 194, and A_magic = 326 from the systematics of folding potentials. The calculated alpha-decay half-lives remain far below one nanosecond for superheavy nuclei with double shell closure and masses above A > 300 independent of the precise knowledge of the magic proton and neutron numbers.

Sustainable housing : reducing the "Ecological footprint" of new wood frame single-family detached houses
Creators: name: Shawkat, Hijran Ali
Publisher: name: University of British Columbia
Year: 2009

description: Sustainability will require that human activity become significantly less material and energy intensive than at the present time. Single family detached housing is one area that has to meet the challenge of sustainability. This thesis investigates the extent of the potential improvement in the environmental performance of wood frame single family detached houses. The Ecological Footprint or Appropriated Carrying Capacity method (EF/ACC) is used to evaluate the environmental performance of the houses examined throughout the study. The thesis came to the following key conclusions: • Land areas required to absorb CO2 emissions are the largest constituent of the Ecological Footprint of single family detached houses followed by land area required to produce energy. These results show clearly that energy, as a major contributor to CO2 emission today and as a resource in the post-fossil fuel era, is the most important environmental concern that has to be addressed. • Operating energy represents the largest component of energy consumption in a house. It constitutes 76% and 73% of the total life cycle energy in the base case study house and the improved house respectively. • The reductions obtained in the improved house compared to the base case study house were: Directly occupied land 48.0% Building materials use 49.2% Life cycle energy consumption 34.0% Life cycle CO2 emission 33.0% The reduction in the ecological footprint of the house is obtained by reducing its size, improving its design and adopting only energy efficient strategies which are cost effective. A 35.6% reduction in the Ecological Footprint of the base study house is obtained. The Ecological Footprint of the improved house is 58.68 in comparison to 91.06 ha in the base case study house. A greater reduction could have been achieved without the limits imposed by EF/ACC method use and the commitment to the principles of cost effectiveness and minimum change in life style.

description: Using the Hubbard chain at quarter filling as a model system, we study the ground state properties of highly doped antiferromagnets. In particular, the Hubbard chain at quarter filling is unstable against 2k_F- and 4k_F-periodic potentials, leading to a large variety of charge and spin ordered ground states. Employing the density matrix renormalization group method, we compare the energy gain of the ground state induced by different periodic potentials. For interacting systems the lowest energy is found for a 2k_F-periodic magnetic field, resulting in a band insulator with spin gap. For strong interaction, the 4k_F-periodic potential leads to a half-filled Heisenberg chain and thus to a Mott insulating state without spin gap. This ground state is more stable than the band insulating state caused by any non-magnetic 2k_F-periodic potential. Adding more electrons, a cluster-like ordering is preferred.

description: Ultrasonic imaging algorithms used in many clinical and industrial applications consist of three steps: A data pre-processing, an image formation and an image post-processing step. For efficiency, image formation often relies on an approximation of the underlying wave physics. A prominent example is the Delay-And-Sum (DAS) algorithm used in reflectivity-based ultrasonic imaging. Recently, deep neural networks (DNNs) are being used for the data pre-processing and the image post-processing steps separately. In this work, we propose a novel deep learning architecture that integrates all three steps to enable end-to-end training. We examine turning the DAS image formation method into a network layer that connects data pre-processing layers with image post-processing layers that perform segmentation. We demonstrate that this integrated approach clearly outperforms sequential approaches that are trained separately. While network training and evaluation is performed only on simulated data, we also showcase the potential of our approach on real data from a non-destructive testing scenario.

description: The COnstrain Dark Energy with X-ray clusters (CODEX) sample contains the largest flux limited sample of X-ray clusters at $0.35 < z < 0.65$. It was selected from ROSAT data in the 10,000 square degrees of overlap with BOSS, mapping a total number of 2770 high-z galaxy clusters. We present here the full results of the CFHT CODEX program on cluster mass measurement, including a reanalysis of CFHTLS Wide data, with 25 individual lensing-constrained cluster masses. We employ $lensfit$ shape measurement and perform a conservative colour-space selection and weighting of background galaxies. Using the combination of shape noise and an analytic covariance for intrinsic variations of cluster profiles at fixed mass due to large scale structure, miscentring, and variations in concentration and ellipticity, we determine the likelihood of the observed shear signal as a function of true mass for each cluster. We combine 25 individual cluster mass likelihoods in a Bayesian hierarchical scheme with the inclusion of optical and X-ray selection functions to derive constraints on the slope $α$, normalization $β$, and scatter $σ_{\ln λ| μ}$ of our richness-mass scaling relation model in log-space: $\left = αμ+ β$, with $μ= \ln (M_{200c}/M_{\mathrm{piv}})$, and $M_{\mathrm{piv}} = 10^{14.81} M_{\odot}$. We find a slope $α= 0.49^{+0.20}_{-0.15}$, normalization $ \exp(β) = 84.0^{+9.2}_{-14.8}$ and $σ_{\ln λ| μ} = 0.17^{+0.13}_{-0.09}$ using CFHT richness estimates. In comparison to other weak lensing richness-mass relations, we find the normalization of the richness statistically agreeing with the normalization of other scaling relations from a broad redshift range ($0.0

The caregivers of persons living with HIV/AIDS: the experience of caring for a dying family member at home
Creators: name: Stajduhar, Kelli Isabel
Publisher: name: University of British Columbia
Year: 2009

description: While some research has been conducted on HIV/AIDS family caregiving, it is limited in addressing the experience of family members who provide care to persons with HIV/AIDS (PWHIV/AIDS) who are dying at home and planning for a home death. Furthermore, much of the general family caregiving research focuses on caregiving tasks and related effects on the caregiver. The purpose of this study was to explore the day-to-day experiences of family members who care for their dying loved one at home with HIV/AIDS. Seven family members who were caring for or had cared for a PWHIV/AIDS at home in the last year were interviewed using an unstructured interview format. Verbatim transcripts of the interviews were analyzed using the constant-comparative method and the methodological guidance of grounded theory. The data analysis contributed to the development of a substantive theory of HIV/AIDS family caregiving. The findings revealed that work characterized the experiences of family members while they lived in a world of uncertainty and stigma. Promising to fulfill the wishes of the loved one lead family members to engage in both personal and pragmatic work. In order to manage their work, caregivers developed various strategies such as seeking support and working as a team. Several conditions affected the caregivers' strategies such as the accessibility of services and the nature of support. These conditions and strategies ultimately resulted in a variety of consequences that affected the caregivers' bereavment. HIV/AIDS family caregiving was an intense, emotional, and powerful experience. It was an experience filled with pride and enrichment, or conversely, with anger and disillusionment. Coping with the extensive demands of HIV/AIDS family caregiving required considerable time, energy, and commitment that often went unrecognized and unsupported. Findings reflect a significant need for interventions designed to provide direct and effective support for HIV/AIDS family caregivers. Failure to address the needs of caregivers is not only morally and ethically unacceptable but also demonstrates a myopic view of the caregivers' experiences. The richness of the caregivers' stories and the impact on their lives cannot be denied and they demand creative, professional solutions.

We improve current bounds on the {7/4}n-3$, slightly improving the bound of Axenovich. We make small improvements on bounds of Erd\H os and Gyárfás by showing ${5/6}n+1\leq f(n,4,5)$ and for all even $n\not\equiv 1 \pmod 3$, $f(n,4,5)\leq n-1$ . For a complete bipartite graph $G=K_{n,n}$, we show an n-color construction to color the edges of $G$ so that every $C_4\subseteq G$ is colored by at least three colors. This improves the best known upper bound of M. Axenovich, Z. Füredi, and D. Mubayi.

description: We describe the first DNS-based measurement of the complete mean response of a turbulent channel flow to small external disturbances. Space-time impulsive perturbations are applied at one channel wall, and the linear response describes their mean effect on the flow field as a function of spatial and temporal separations. The turbulent response is shown to differ from the response a laminar flow with the turbulent mean velocity profile as base flow.

description: The wave turbulence theory predicts that a conservative system of nonlinear waves can exhibit a process of condensation, which originates in the singularity of the Rayleigh-Jeans equilibrium distribution of classical waves. Considering light propagation in a multimode fiber, we show that light condensation is driven by an energy flow toward the higher-order modes, and a bi-directional redistribution of the wave-action (or power) to the fundamental mode and to higher-order modes. The analysis of the near-field intensity distribution provides experimental evidence of this mechanism. The kinetic equation also shows that the wave-action and energy flows can be inverted through a thermalization toward a negative temperature equilibrium state, in which the high-order modes are more populated than low-order modes. In addition, a Bogoliubov stability analysis reveals that the condensate state is stable.

description: We report on the implementation of evaporative cooling of a magnetically guided beam by adsorption on a ceramic surface. We use a transverse magnetic field to shift locally the beam towards the surface, where atoms are selectively evaporated. With a 5~mm long ceramic piece, we gain a factor $1.5\pm0.2$ on the phase space density. Our results are consistent with a 100% efficiency of this evaporation process. The flexible implementation that we have demonstrated, combined with the very local action of the evaporation zone, makes this method particularly suited for the evaporative cooling of a beam.

Continuous phase transitions with a convex dip in the microcanonical entropy

description: The appearance of a convex dip in the microcanonical entropy of finite systems usually signals a first order transition. However, a convex dip also shows up in some systems with a continuous transition as for example in the Baxter-Wu model and in the four-state Potts model in two dimensions. We demonstrate that the appearance of a convex dip in those cases can be traced back to a finite-size effect. The properties of the dip are markedly different from those associated with a first order transition and can be understood within a microcanonical finite-size scaling theory for continuous phase transitions. Results obtained from numerical simulations corroborate the predictions of the scaling theory.

description: Liquid-metal infiltrated Cu30Mo70 (weigth percentage) is subjected to severe plastic deformation using high pressure torsion. The initially equiaxed dual phase structure is gradually transformed into a lamellar structure composed of individual Cu and Mo layers. The thickness of the lamellae varies between the micrometer and nanometer ranges depending on the amount of applied strain. Consistent with the refinement of the microstructural features, strength and hardness substantially increase. In addition, an acceptable ductility is found in the intermediate deformation range. An assessment of the damage tolerance of the produced composites is performed by measuring the fracture toughness in different crack propagation directions. The results indicate the development of a pronounced anisotropy with increasing degree of deformation which is an effect of the concurrent alignment of the nanostructured lamellar composite into the shear plane.

description: We give a sufficient condition for Kripke completeness of modal logics enriched with the transitive closure modality. More precisely, we show that if a logic admits what we call definable filtration (ADF), then such an expansion of the logic is complete; in addition, has the finite model property, and again ADF. This argument can be iterated, and as an application we obtain the finite model property for PDL-like expansions of logics that ADF.

description: String matching algorithms in the presence of abbreviations, such as in Stock Keeping Unit (SKU) product catalogs, remains a relatively unexplored topic. In this paper, we present a unified architecture for SKU search that provides both a real-time suggestion system (based on a Trie data structure) as well as a lower latency search system (making use of character level TF-IDF in combination with language model vector embeddings) where users initiate the search process explicitly. We carry out ablation studies that justify designing a complex search system composed of multiple components to address the delicate trade-off between speed and accuracy. Using SKU search in the Dynamics CRM as an example, we show how our system vastly outperforms, in all aspects, the results provided by the default search engine. Finally, we show how SKU descriptions may be enhanced via generative text models (using gpt-3.5-turbo) so that the consumers of the search results may get more context and a generally better experience when presented with the results of their SKU search.

description: Η δυνατότητα εκτίμησης της ακριβούς ηλικίας των ατόμων ενός πληθυσμού είναι από τα πιο χρήσιμα εργαλεία στην διαχείριση της άγριας πανίδας καθώς μας επιτρέπει τη μελέτη της δυναμικής του είδους και μας δίνει τη δυνατότητα επιλογής του κατάλληλου κάθε φορά διαχειριστικού σχεδίου. Στην παρούσα εργασία έγινε η εκτίμηση ηλικίας από τις στρώσεις οδοντίνης σε 43 άτομα αλεπούς του ελλαδικού χώρου. Έγινε απασβέστωση των δοντιών, τομή τους , χρωματισμός των τομών, τοποθέτηση τους σε αντικειμενοφόρες πλάκες και εξέταση τους στο μικροσκόπιο. Εκτιμήθηκε η ηλικία κάθε ατόμου και έγινε η κατανομή των συχνοτήτων των ατόμων στο σύνολό τους και κάθε φύλου ξεχωριστά σε κάθε ηλικία, σε κλάσεις ηλικιών και σε αναπαραγωγικά και μη. Υπολογίστηκαν τα ποσοστά θνησιμότητας σε κάθε μία από τις παραπάνω αναφερόμενες περιπτώσεις και βρέθηκε ο δείκτης αναλογίας νεαρά : ενήλικα άτομα. Ο πληθυσμός εκτιμήθηκε σταθερός με πολλά γηραιά άτομα. Τα ποσοστά θνησιμότητας ήταν υψηλά στις μικρές ηλικίες (ως 3 ετών, 45%) και στα γηραιά άτομα(>8 ετών 37,2%). Το ποσοστό θνησιμότητας στα μη αναπαραγωγικά άτομα ήταν κατά πολύ περισσότερο (62,8%)από τα αναπαραγωγικά άτομα (37,2%)του δείγματος. Ιδιαίτερο ενδιαφέρον παρουσίασαν τα υψηλά ποσοστά θνησιμότητας αρσενικών αναπαραγωγικών ατόμων σε σχέση με τα θηλυκά και τα υψηλά ποσοστά θνησιμότητας στα γηραιά θηλυκά άτομα. Τα ευρήματα συγκρίθηκαν με αντίστοιχα άλλων ερευνητών και συζητήθηκαν διεξοδικά. Τέλος προτάθηκαν δυνατότητες περαιτέρω εφαρμογών της συγκεκριμένης τεχνικής εκτίμησης ηλικίας.
description: Exact individual age determination of a population is one of the most useful tools in the hands of wild life managers, because it gives the potential of understanding the population dynamics of the species and of choosing the proper management action. In this paper there has been age determination by annual dentine layers in 43 red foxes in Greece. The teeth were decalcified, sectioned, stained, mounted on slides and examined with microscope. After the age determination for each fox, there has been estimation of the distribution of the population and of every gender separately in age classes and in reproductive – non reproductive individuals. Mortality rates in every case were estimated and the cub: adult ratio was calculated. The population was found to be stable with lots of old individuals. Mortality rates were found to be high at the young ages (<3 years old, 45%), at the old ages (>8 years old) and for the non reproductive foxes (62.8%). The high mortality rate of the male reproductive foxes was found of great interest. The results were compared with others researchers’ and were discussed extensively. Further application potentials of this technique were suggested.

description: A previously overlooked constraint for the distribution of entanglement in three-qubit systems is exploited for the first time and used to reveal a new genuine tripartite entanglement measure. It is interpreted as the area of a so-called concurrence triangle and is compared with other existing measures. The new measure is found superior to previous attempts for different reasons. A specific example is illustrated to show that two tripartite entanglement measures can be inequivalent due to the high dimensionality of the Hilbert space.

description: In this work, we propose a novel method for vocabulary selection which enables simultaneous speech recognition systems for lectures to automatically adapt to the diverse topics that occur in educational and scientific lectures. Utilizing materials that are available before the lecture begins, such as lecture slides, our proposed framework iteratively searches for related documents on the World Wide Web and generates a lecture-specific vocabulary and language model based on the resulting documents. In this paper, we introduce a novel method for vocabulary selection where we rank vocabulary that occurs in the collected documents based on a relevance score which is calculated using a combination of word features. Vocabulary selection is a critical component for topic adaptation that has typically been overlooked in prior works. On the interACT German-English simultaneous lecture translation system our proposed approach significantly improved vocabulary coverage, reducing the out-of-vocabulary rate on average by 57.0% and up to 84.9%, compared to a lecture-independent baseline. Furthermore, our approach reduced the word error rate by up to 25.3% (on average 13.2% across all lectures), compared to a lectureindependent baseline.
