Communication

description: It has long been established that there is a correlation between the dialog behavior of a participant and how influential he or she is perceived to be by other discourse participants. In this paper we explore the characteristics of communication that make someone an opinion leader and develop a machine learning based approach for the automatic identification of discourse participants that are likely to be influencers in online communication. Our approach relies on identification of three types of conversational behavior: persuasion, agreement/disagreement, and dialog patterns.

description: Die Lebensphase „Alter“ ist vielfältigen Veränderungen unterworfen. Neben der quantitativen Ausdehnung in der Biografie des Einzelnen, vollzieht sich eine Diversifizierung von Lebenslagen und -verläufen. Dabei kommt in der Wissens- und Informationsgesellschaft auch in dieser Lebensphase der Bildung eine Schlüsselrolle zu. So haben Personen in der nachberuflichen bzw. nachfamiliären Phase auch die Möglichkeit an akademischen Veranstaltungen zu partizipieren. Während die Bedeutung dieser Angebote für die Teilnehmenden bereits umfassend theoretisch und empirisch beleuchtet wurde, sind Studien zu den dabei transportierten Alter(n)sbildern sowie zu den Alter(n)svorstellungen Studierender bislang weitgehend ein Desiderat. So werden zwar mögliche Auswirkungen des intergenerationellen Austausches diskutiert, empirische Evidenzen dafür finden sich jedoch bislang kaum. Die vorliegende Arbeit nimmt daher organisationale und individuelle Alter(n)sbilder in den Blick und geht insbesondere den Fragen nach, wie die Angebots-landschaft der nachberuflichen wissenschaftlichen Weiterbildung an Universitäten ausgestaltet ist, welche Vorstellungen vom Alter und Altern die Senioren- und Regel-studierenden aufweisen und welche Bedeutung dabei das intergenerationelle Lernen spielt. Die Ergebnisse verdeutlichen, dass sich Alter(n)sbilder multidirektional sowie multi-dimensional gestalten und geben Hinweise auf deren Situationsspezifik und Variabilität im Hochschulkontext.

description: With Monte Carlo methods, we investigate the universality class of the depinning transition in the two-dimensional Ising model with quenched random fields. Based on the short-time dynamic approach, we accurately determine the depinning transition field and both static and dynamic critical exponents. The critical exponents vary significantly with the form and strength of the random fields, but exhibit independence on the updating schemes of the Monte Carlo algorithm. From the roughness exponents $ζ, ζ_{loc}$ and $ζ_s$, one may judge that the depinning transition of the random-field Ising model belongs to the new dynamic universality class with $ζ\neq ζ_{loc}\neq ζ_s$ and $ζ_{loc} \neq 1$. The crossover from the second-order phase transition to the first-order one is observed for the uniform distribution of the random fields, but it is not present for the Gaussian distribution.

Finding 'I' in University: Effects of Psychosocial Intervention on Undergraduates with Attention-Deficit/Hyperactivity Disorder (ADHD) Symptoms
Creators: name: Gordon, Laura L.
Publisher: name: Werklund School of Education
Year: 2020
Subjects: subject: Attention-Deficit/Hyperactivity Disorder (ADHD), undergraduate, university, college, students, sense of belonging, problem-focused coping, psychosocial intervention
subject: Educational Psychology

description: Students with Attention-Deficit/Hyperactivity Disorder (ADHD) are less likely to use academic coping strategies effectively (DuPaul et al., 2009; Kaminski et al., 2006) and less likely to graduate from college (Barkley et al., 2008; Kuriyan et al., 2013). Given that students’ sense of belonging to their college is associated with academic persistence/student retention (Hausmann et al., 2007; Morrow & Ackermann, 2012; O’Keeffe, 2013; Tinto, 1999), the current study sought to investigate the effects of a six-week group psychosocial intervention, adapted from an adult ADHD cognitive-behavioural therapy (CBT) manual (Safren et al., 2005) on two forms of problem-focused coping (planning/self-management and seeking support from institutional resources) and five components of sense of belonging (perceived faculty support, perceived empathetic faculty understanding, classroom comfort, perceived peer support, and feelings of isolation) among undergraduate students with ADHD symptoms. An ancillary purpose of the current study was to investigate the relationships between these two problem-focused coping strategies and these five sense of belonging components among undergraduate students with ADHD symptoms. Results indicated that participants reported significantly heightened perceived peer support and significantly lessened feelings of isolation post-intervention. However, no significant differences were indicated on the remaining three sense of belonging components (perceived faculty support, perceived empathetic faculty understanding, and classroom comfort) or either of the problem-focused subscales (planning/self-management and seeking support from institutional resources). Moreover, no associations were found between problem-focused coping and sense of belonging. It was concluded that the group psychosocial intervention significantly improved perceived peer support and reduced feelings of isolation among undergraduates with ADHD symptoms. Implications and limitations of the current study as well as future directions for research are discussed.
A menu based approach to improve uptake and completion of pulmonary rehabilitation programmes for individuals with COPD
Creators: name: Barradell, Amy
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Pulmonary Rehabilitation (PR) is evidenced-based for individuals living with Chronic Obstructive Pulmonary Disease (COPD) and, upon referral, a menu of options is available. However, uptake and completion remains challenging. There is growing interest in shared decision making (SDM) to support individuals and healthcare professionals (HCPs) make optimal healthcare decisions. However, its adoption within PR is in its infancy and currently no interventions to facilitate SDM exist. This thesis sought to design and develop an intervention to facilitate SDM between individuals and HCPs about PR treatment options that was feasible and acceptable to all. Qualitative, quantitative, and systematic review methodology were adopted to inform the intervention’s design (chapters 2, 3, and 4). A systematic development process was implemented (chapter 5). A mixed methods study evaluated its feasibility and acceptability with individuals with COPD and PR HCPs (chapter 6). Whilst there was an appetite for a menu-based approach, facilitated by SDM, barriers to its adoption included: individuals and HCPs having insufficient knowledge of the menu and HCPs not viewing the options equally. All expressed a need for a knowledge translation and decision support tool to facilitate SDM into PR decision-making (chapter 2). Chapter 3 showed that HCPs exhibit implicit bis towards the COPD health behaviours smoking and exercising. As implicit (and explicit) bias influence behaviours, these results in collaboration with findings from chapter 2 provided an argument for the inclusion of training to upskill HCPs in SDM, including the importance of unbiased communications. The systematic review (chapter 4) showed a three-pronged SDM intervention including components at the individual, the HCP, and the consultation level could facilitate SDM in PR. The developed intervention included a patient decision aid, decision coaching training for PR HCPs, and a consultation prompt (chapter 5). Upon testing, the intervention proved feasible, acceptable, and could be delivered with fidelity.

description: While Modern Standard Arabic is the formal spoken and written language of the Arab world, dialects are the major communication mode for everyday life; identifying a speaker’s dialect is thus critical to speech processing tasks such as automatic speech recognition, as well as speaker identification We examine the role of prosodic features (intonation and rhythm) across four Arabic dialects: Gulf, Iraqi, Levantine, and Egyptian, for the purpose of automatic dialect identification We show that prosodic features can significantly improve identification, over a purely phonotactic-based approach, with an identification accuracy of 86.33% for 2m utterances.
3-D Radiative Transfer Calculations of Radiation Feedback from Massive Black Holes: Outflow of Mass from the Dusty "Torus"

description: Observational and theoretical arguments suggest that the momentum carried in mass outflows from AGN can reach several times L / c, corresponding to outflow rates of hundreds of solar masses per year. Radiation pressure on lines alone may not be sufficient to provide this momentum deposition, and the transfer of reprocessed IR radiation in dusty nuclear gas has been postulated to provide the extra enhancement. The efficacy of this mechanism, however, will be sensitive to multi-dimensional effects such as the tendency for the reprocessed radiation to preferentially escape along sight-lines of lower column density. We use Monte Carlo radiative transfer calculations to determine the radiation force on dusty gas residing within approximately 10 parsecs from an accreting super-massive black hole. We calculate the net rate of momentum deposition in the surrounding gas and estimate the mass-loss rate in the resulting outflow as a function of solid angle for different black hole luminosities, sightline-averaged column densities, clumping parameters, and opening angles of the dusty gas. We find that these dust-driven winds carry momentum fluxes of 1-5 times L / c and correspond to mass-loss rates of 10-100 solar masses per year for a 10^8 solar mass black hole radiating at or near its Eddington limit. These results help to explain the origin of high velocity molecular and atomic outflows in local ULIRGs, and can inform numerical simulations of galaxy evolution including AGN feedback.

description: We report results of experiments which build and refine models of rhetorical-semantic relations such as Cause and Contrast. We adopt the approach of Marcu and Echihabi (2002), using a small set of patterns to build relation models, and extend their work by refining the training and classification process using parameter optimization, topic segmentation and syntactic parsing. Using human-annotated and automatically-extracted test sets, we find that each of these techniques results in improved relation classification accuracy.

description: Context: The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has changed our view of the Milky Way from an inactive to an active star-forming machine. Within this scenario, we present a near-infrared spectrophotometric study of the stellar content of the compact H II region Sh2-152. Aims: We aim to determine the distance, extinction, age, and mass of Sh2-152, using for the first time near-infrared stellar classification for several sources in the region. Methods: Using our near-infrared (J, H, and Ks) photometry and the colour-magnitude diagram for the cluster field, we selected 13 bright stars, candidate members of the reddened cluster's main sequence, for H- and K- spectroscopy and spectral classification. This near-infrared information was complemented with an optical spectrum of the ionizing central star to confirm its spectral nature. Results: From the 13 spectroscopically observed stars, 5 were classified as B-type, 3 as G-type, 2 were young stellar objects (YSOs), and 3 remained unclassified (because of the poor data quality). The cluster's extinction varies from A_{Ks}=0.5 to 2.6 magnitudes (A_V=4.5 to 24 magnitudes) and the distance is estimated to be 3.21\pm0.21 kpc. The age of the cluster is younger than 9.4 Myr and the lower limit to the total mass of the cluster is (2.45\pm0.79)\cdot10^3 M_{Sun}. We compare the number of ionizing photons emitted from the OB-type stars with the Lyman continuum photons derived from the radio observations and conclude that both quantities are consistent for the central region of Sh2-152. In contrast, the main ionizing source of the lower region remains unidentified.

This is based on the cluster picture and the assumption that the charged hadrons that flow outward from the surface of the overlapping region of the colliding nuclei move primarily parallel to the reaction plane. We also point out the there is a strong electric field induced by the transient magnetic field during the parton production in the initial phase of the relativistic heavy-ion collision and discuss its possible relevance to the scenario.

description: In an empirical study participants were asked to rate the perceived degree of certainty of utterances that contained either the modal would or main verb be (e.g. That would be me vs. That’s me), and which were also variously produced with one of three intonational contours (downstepped, declarative, and yes-no question). We found that both downstepped contour and epistemic would made a significant and independent contribution to the assessment of speaker certainty. That is, participants rated utterances with the downstepped contour as most certain, followed by those with the declarative contour, while the yes-no question contour was perceived as highly uncertain. Similarly, participants rated speakers' responses with epistemic would as significantly more certain than those without it.

Subjects: Teacher education and professional development of educators

description: This paper is the last of three reflections on how teacher research literacy is understood and enacted in the English policy context, with a view to developing the literature base and informing practice. The final BERA-RSA (2014) report into 'Research and the Teaching Profession' proposes that all teachers should be ‘research literate’, which is defined as being able to access and assess existing research. This document also calls for teacher education to provide teachers with the agency to engage in their own research in addition to engaging with external research. It is the understandings and practices of research literacy in teachers’ continuing professional development that are here presented. A survey of in-service teachers (n=66), semi-structured interviews with survey respondents (n=4) and two case studies of primary and secondary teaching schools show convergent understandings and practices of research literacy in professional development depending upon school context and involvement of higher education.

description: We present an investigation of segments that map to GLOBAL LIES, that is, the intent to deceive with respect to salient topics of the discourse. We propose that identifying the truth or falsity of these CRITICAL SEGMENTS may be important in determining a speaker’s veracity over the larger topic of discourse. Further, answers to key questions, which can be identiﬁed a priori, may represent emotional and cognitive HOT SPOTS, analogous to those observed by psychologists who study gestural and facial cues to deception. We present results of experiments that use two different deﬁnitions of CRITICAL SEGMENTS and employ machine learning techniques that compensate for imbalances in the dataset. Using this approach, we achieve a performance gain of 23.8% relative to chance, in contrast with human performance on a similar task, which averages substantially below chance. We discuss the features used by the models, and consider how these ﬁndings can inﬂuence future research.

description: We present an analysis of the ages and star-formation history of the F-type stars in the Upper Scorpius (US), Upper Centaurus-Lupus (UCL) and Lower Centaurus-Crux (LCC) subgroups of Scorpius-Centaurus. We find that 1) our empirical isochrones are consistent with the previously published age-rank of the Sco-Cen subgroups, 2) LCC and UCL appear to reach the main sequence turn-on at spectral types ~F4 and ~F2, respectively. An analysis of the A-type stars shows US reaching the main sequence at about spectral type ~A3. 3) The median ages for the pre-main sequence members of UCL and LCC are 16 Myr and 17 Myr, respectively, in agreement with previous studies, however we find that 4) Upper Sco is much older than previously thought. The luminosities of the F-type stars in US are typically a factor of ~2.5 less luminous than predicted for a 5 Myr old population for four sets of evolutionary tracks. We reexamine the evolutionary state and isochronal ages for the B-, A-, and G-type Upper Sco members, and the evolved M supergiant Antares, and estimate a revised mean age for Upper Sco of 11+/-1+/-2 Myr (statistical, systematic). Using radial velocities and Hipparcos parallaxes we calculate a lower limit on the kinematic expansion age for Upper Sco of >10.5 Myr (99% confidence). However, the data are statistically consistent with no expansion. We reevaluate the inferred masses for the known substellar companions in Upper Sco using the revised age. Specifically, we estimate the mass of 1RXS J1609-2105b to be 14^{+2}_{-3} Mjup, suggesting that it is a brown dwarf rather than a planet. Finally, we find the fraction of F-type stars exhibiting Ha emission and/or a K-band excess consistent with accretion to be 0/17 (<19%; 95% C.L.) in US at ~11 Myr, while UCL has 1/41 (2^{+5}_{-1}%; 68% C.L.) accretors and LCC has 1/50 (2^{+4}_{-1}%; 68% C.L.) accretors at ~16 Myr and ~17 Myr, respectively.

Synergistic Effect between Surfactant and Nanoparticles on the Stability of Methane Foam in EOR Processes

Publisher: name: Schulich School of Engineering
Year: 2020
Subjects: subject: Engineering

description: This thesis investigates the enhanced oil recovery (EOR) potential of nanoparticles stabilized methane foam to improve the performance of conventional gas injection methods for oil reservoirs. This work conducts static and dynamic tests that help in understanding the sodium fatty alcohol polyoxyethylene ether sulfate surfactant (AES) and silica nanoparticles with alumina coating (SNOWTEX-AK) interaction mechanisms and in designing foam injection processes. With a carefully designed mixture of surfactant and nanoparticles at certain concentration ratios in the foaming solutions, the generated foam can overcome the challenges such as surfactant adsorption, effects of crude oil and oil saturation, and salinity in reservoir conditions. The extent to which nanoparticles surface is covered with surfactant governs the foam stability both in static and dynamic conditions, with both heavy oil and brine present. In particular, when the nanoparticle surface is covered by a partial monolayer of surfactant molecules, foam stabilized by the partially covered nanoparticles provides a step-change improvement in performance for EOR due to its high dynamic stability. In contrast, foam stabilized by nanoparticles covered by a bilayer of surfactant has performance comparable to a surfactant-only foam, and both are ineffective for EOR due to their poor dynamic stability when contacting reservoir fluids.

description: In this paper, we show that linguistically motivated pronunciation rules can improve phone and word recognition results for Modern Standard Arabic (MSA). Using these rules and the MADA morphological analysis and disambiguation tool, multiple pronunciations per word are automatically generated to build two pronunciation dictionaries; one for training and another for decoding. We demonstrate that the use of these rules can significantly improve both MSA phone recognition and MSA word recognition accuracies over a baseline system using pronunciation rules typically employed in previous work on MSA Automatic Speech Recognition (ASR). We obtain a significant improvement in absolute accuracy in phone recognition of 3.77%–7.29% and a significant improvement of 4.1% in absolute accuracy in ASR.

“Registers of Empathy” of Visitors towards the “Painful History” of South Korea within South Korean National Museums
Creators: name: Oh, Minju
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: This thesis examines the emotional representation of “painful history” in two museum and heritage site in South Korea dealing with the Japanese colonial period (1910-1945). The concept of “painful history” is used to describe the specific context of South Korea still coming terms with colonial trauma. The aim of the research is to understand the emotional engagement of museum visitors with this period of history presented in two case studies, Independence Hall of Korea, and Seodamun Prison Hall. The study reveals strongly “the poetics of the displays” that aim to promote national pride in both sites, focusing particularly on the experience of ordinary people of resisted Japanese occupation. At the same time, there is a tension within these sites in presenting highly emotionally charged painful history (particularly around violence and torture of South Korean citizens), and asking visitors to move beyond negative emotions towards the Japanese. The visitor interviews reveal a range of emotional engagements, including negative emotions such as rage, anger and shame and guilt. Building on Smith’s work on registers of engagement, this thesis explores the notion of “hot and cold empathy” and ultimately develops the notions of “registers of empathy” to explore how these different emotional engagements enable visitors to process their museum visits in an empathetic way. The thesis contributes to the emergent field of museum studies in South Korea, concluding that to understand their social role, museums need to recognise the negative dimension of the visitor emotional engagement. Furthermore, this emotion-based research of visitors in museums in South Korea can offer a new aspect to museum studies in other countries, particularly related to museum narratives and visitor meaning making around painful history from the perspectives of the victims.

description: We present a method for lexical simplification Simplification rules are learned from a comparable corpus, and the rules are applied in a context-aware fashion to input sentences. Our method is unsupervised. Furthermore, it does not require any alignment or correspondence among the complex and simple corpora. We evaluate the simplification according to three criteria: preservation of grammaticality, preservation of meaning, and degree of simplification Results show that our method outperforms an established simplification baseline for both meaning preservation and simplification, while maintaining a high level of
grammaticality.

The system is known to exhibit a phase transition for low enough T where macroscopic cycles appear. We observe that the lengths of such cycles are distributed according to Poisson-Dirichlet. This can be explained heuristically using a stochastic coagulation-fragmentation process for long cycles, which is supported by numerical data.

description: Ziel dieser Arbeit war, das Gesamtüberleben nach blasenerhaltender Therapie bei muskel-invasivem Harnblasenkarzinom zu untersuchen. Es wurden alle Daten der Patienten, die an der Klinik für Strahlentherapie des Universitätsklinikums Halle (2006 - 2012) an einem muskel-invasiven Harnblasenkarzinom radiochemotherapiert wurden, retrospektiv ausgewertet. Die Daten wurden mittels SPSS verarbeitet. Es wurden Kaplan-Meier-Kurven erstellt und Häufigkeiten berechnet. Die 3- bzw. 5-Jahresüberlebensrate betrug 48 % bzw. 38 %. Einen Einfluss auf das Gesamtüberleben zeigten die Anzahl der vorangegangenen TUR und die Komorbiditäten. Ein Trend konnte für das mediane T-Stadium vor Beginn der Therapie und für den Patientenwunsch nachgewiesen werden. Der Charlson Comorbidity Index, das Geschlecht, die Therapienebenwirkungen, das Alter und das angewendete Chemo- und Radiotherapieschema zeigten keinen Einfluss auf das Gesamtüberleben. Auch die Rezidivraten wurden erfasst. Das Gesamtüberleben nach Radiochemotherapie nach TUR-B ist nach den vorliegenden Studien in etwa vergleichbar mit dem Gesamtüberleben nach radikaler Zystektomie. Die trimodale Therapie bietet somit eine sinnvolle alternative Therapie für muskelinvasive Harnblasenkarzinome.
description: The aim of this work was to investigate the overall survival after bladder-preserving therapy in muscle-invasive bladder cancer. All data from patients undergoing radiochemotherapy on a muscle-invasive bladder carcinoma were retrospectively evaluated at the Department of Radiotherapy of the University Hospital in Halle (2006 - 2012). The data was processed using SPSS. Kaplan-Meier curves were created and frequencies calculated. The 3- and 5-year survival rates were 48% and 38%, respectively. An significant influence on overall survival was shown by the number of previous TUR and the comorbidities. A trend could be demonstrated for the median T-stage before the start of therapy and for the patient's request. The Charlson Comorbidity Index, gender, treatment side effects, age, and the chemo- and radiotherapy regimen used did not affect overall survival. The recurrence rates were also recorded. The overall survival after chemoradiotherapy after TUR-B is about comparable to the overall survival after radical cystectomy. The trimodal therapy thus provides a useful alternative therapy for muscle invasive bladder cancer.

Die quantitative Bewertung dieser reaktiven Intermediate in vivo ist essentiell für das Verständnis von Transketolase-katalysierten Reaktionen auf molekularer Ebene. Dabei wurde Glycolaldehyd als zentrales Intermediat der Maillard-Reaktion in vivo identifiziert. Weiterhin konnten grundlegende Erkenntnisse über die seitenspezifische Modifikation von Proteinen gewonnen werden. Daher ist diese Arbeit ausschlaggebend für das Verständnis der physikochemischen Veränderungen von Proteinen und in der zukünftigen Forschung für die anschließende Bewertung ihrer Rolle in Nahrungsmitteln und in vivo.
description: This dissertation extends the current knowledge on the role of the transketolase-reaction in the suppression of reactive carbonyl compounds and their follow-up products (advanced glycation endproducts). The quantitative assessment of these reactive precursor compounds in vivo is essential in the understanding of the transketolase metabolism on a molecular level. In addition, glycolaldehyde was identified as a central intermediate of the Maillard reaction. Furthermore, basic knowledge about the site-specific modification of proteins was obtained. Therefore, this work is fundamental for understanding the physicochemical changes of proteins and the subsequent assessment of their role in foodstuffs and in vivo.

description: We discuss perception studies of two low level indicators of discourse phenomena by Swedish, Japanese, and Chinese native speakers. Subjects were asked to identify upcoming prosodic boundaries and disfluencies in Swedish spontaneous speech. We hypothesize that speakers of prosodically unrelated languages should be less able to predict upcoming phrase boundaries but potentially better able to identify
disfluencies, since indicators of disfluency are more likely to depend upon lexical, as well as acoustic information. However, surprisingly, we found that both phenomena were fairly well recognized by native and non-native speakers, with, however, some possible interference from word tones for the Chinese subjects.

description: This paper is concerned with an important matrix condition in compressed sensing known as the restricted isometry property (RIP). We demonstrate that testing whether a matrix satisfies RIP is NP-hard. As a consequence of our result, it is impossible to efficiently test for RIP provided P \neq NP.

description: Faced with the difficulties of finding an operationalized definition of backchannels, we have previously proposed an intermediate, auxiliary unit – the very short utterance (VSU) – which is defined operationally and is automatically extractable from recorded or ongoing dialogues. Here, we extend that work in the following ways: (1) we test the extent to which the VSU/NONVSU distinction corresponds to backchannels/non-backchannels in a different data set that is manually annotated for backchannels – the Columbia Games Corpus; (2) we examine to the extent to which VSUS capture other short utterances with a vocabulary similar to backchannels; (3) we propose a VSU method for better managing turn-taking and barge-ins in spoken dialogue systems based on detection of backchannels; and (4) we attempt to detect backchannels with better precision by training a backchannel classifier using durations and inter-speaker relative loudness differences as features. The results show that VSUS indeed capture a large proportion of backchannels – large enough that VSUs can be used to improve spoken dialogue system turntaking; and that building a reliable backchannel classifier working in real time is feasible.

description: Die Bodenverdichtung ist einer der Umweltfaktoren in der Landwirtschaft, die die Bodenfunktionen und das Pflanzenwachstum beeinträchtigen. Einige bodenphysikalische Eigenschaften können leicht mit klassischen Labormethoden gemessen werden. Explizite Informationen über strukturelle Veränderungen des Bodens sind jedoch mit klassischen Methoden nicht möglich. Dies erfordert zerstörungsfreie Messungen, wie z. B. die Röntgen-Computertomographie, eine nicht-invasive 3D-Bildanalysetechnik, mit der das System Boden detaillierter analysiert werden kann. Diese Arbeit, die in drei verschiedene Versuche beinhaltet, kombiniert Parameter, die mit der Computertomographie und klassischen Labormethoden ermittelt wurden. Dabei wird die der Prozess der Bodenverdichtung am Beispiel von Proben aus verschiedenen Bodenbearbeitungsbehandlungen, unterschiedliche Wasserspannungen und verschiedene Texturen im Oberboden analysiert.
description: Soil compaction is one of the environmental factors in agriculture that adversely affect soil functions and crop growth. Some soil physical properties can easily be measured using classic laboratory methods. However, explicit information about soil structural changes cannot be obtained with classic methods. This requires non-destructive measurements such as X-ray computed tomography, a non-invasive 3D image analysis technique that allows analysing the soil pore system in some detail. This study, divided into three separate trials, combines parameters obtained with computed tomography and classic laboratory methods to analyze soil compaction, exemplified on samples from different tillage treatments, different moisture tensions and different textures in the topsoil.
Bose-Einstein Condensation of a Gaussian Random Field in the Thermodynamic Limit

description: We derive the criterion for the Bose-Einstein condensation (BEC) of a Gaussian field $ϕ$ (real or complex) in the thermodynamic limit. The field is characterized by its covariance function and the control parameter is the intensity $u=\|ϕ\|_2^2/V$, where $V$ is the volume of the box containing the field. We show that for any dimension $d$ (including $d=1$), there is a class of covariance functions for which $ϕ$ exhibits a BEC as $u$ is increased through a critical value $u_c$. In this case, we investigate the probability distribution of the part of $u$ contained in the condensate. We show that depending on the parameters characterizing the covariance function and the dimension $d$, there can be two distinct types of condensate: a Gaussian distributed "normal" condensate with fluctuations scaling as $1/\sqrt{V}$, and a non Gaussian distributed "anomalous" condensate. A detailed analysis of the anomalous condensate is performed for a one-dimensional system ($d=1$). Extending this one-dimensional analysis to exactly the point of transition between normal and anomalous condensations, we find that the condensate at the transition point is still Gaussian distributed but with anomalously large fluctuations scaling as $\sqrt{\ln(L)/L}$, where $L$ is the system length. The conditional spectral density of $ϕ$, knowing $u$, is given for all the regimes (with and without BEC).

description: We introduce a new data set which contains both a self-declared friendship network and self-chosen attributes from a ﬁnite list deﬁned by the social networking site. We propose Gaussian Field Harmonic Functions (GFHF), a state-of-the-art graph transduction algorithm, as a novel way of testing the relevance of the friendship network for predicting individual attributes. We show that the underlying self-declared friendship network allows us to predict some but not all attributes. We use Support Vector Machines (SVM) in conjunction with GFHF to show that other attributes such as age or languages spoken are also important.

description: Cross-lingual tasks are especially difficult due to the compounding effect of errors in language processing and errors in machine translation (MT). In this paper, we present an error analysis of a new cross-lingual task: the 5W task, a sentence-level understanding task which seeks to return the English 5W's (Who, What, When, Where and Why) corresponding to a Chinese sentence. We analyze systems that we developed, identifying specific problems in language processing and MT that cause errors. The best cross-lingual 5W system was still 19% worse than the best monolingual 5W system, which shows that MT significantly degrades sentence-level understanding. Neither source-language nor target-language analysis was able to circumvent problems in MT, although each approach had advantages relative to the other. A detailed error analysis across multiple systems suggests directions for future research on the problem.

description: Native-like production of intonational prominence is important for spoken language competency. Non-native speakers may have trouble producing prosodic variation in a second language (L2) and thus, problems in being understood. By identifying common sources of production error, we will be able to aid in the instruction of L2 speakers. In this paper we present results of a production study designed to test the ability of Mandarin L1 speakers to produce prominence in English. Our results show that there are some consistent differences between the L1 and L2 speakers in the use of pitch to indicate prominence, as well as in the accenting of phrase-initial tokens. We also find that we can automatically detect prominence on Mandarin L1 English with 87.23% and an f-measure of 0.866 if we train a classifier with annotated Mandarin L1 English data. Models trained on native English speech can detect prominence in Mandarin L1 English with an accuracy of 74.77% and f-measure of 0.824.
