Nutzung semantischer Informationen aus OSM zur Beschreibung des Nichtwohnnutzungsanteils in Gebäudebeständen

Kunze, Carola 19 July 2013 (has links) (PDF)
Im Bereich der städtebasierten siedlungsstrukturellen Analysen spielen Gebäudedaten mit Informationen zur Gebäudenutzung und dem Gebäudetyp eine wichtige Rolle. Auf diesen Daten basiert die Modellierung von demografischen und sozioökonomischen Kenngrößen, welche bei Aufgaben der Siedlungsentwicklung oder in der Infrastrukturplanung zum Einsatz kommen. Vonseiten der amtlichen Vermessungsanstalten stehen kleinräumige und flächendeckende Daten zur Gebäudenutzung nur in begrenztem Umfang zur Verfügung. Eine darauf aufbauende Bevölkerungsabschätzung ist aus diesem Grund nur eingeschränkt möglich. Das Ziel dieser Arbeit war es, die Integration von nutzergenerierten Geodaten aus dem OpenStreetMap (OSM) Projekt für den Einsatz zur Abschätzung gebäudebasierter Bevölkerungs- und Wohnungszahlen zu untersuchen. Der Fokus liegt dabei besonders auf der Abgrenzung von Wohn- und Nichtwohnnutzung innerhalb von Gebäuden. Diese Informationen sind in den amtlichen Geobasisdaten nicht zu finden, können jedoch aus OSM Punkt- und Polygondaten extrahiert werden. Hauptgegenstand der Untersuchung ist die Entwicklung eines Modells zur Integration der Nichtwohnnutzungsinformationen aus OSM, welches Gewerbeinformationen anhand der OSM-Tags analysiert. Dazu war neben einer geeigneten Typologie, die Festlegung von Regeln zur Verarbeitung mehrerer Gewerbe in einem amtlichen Gebäude notwendig. Über räumliche Verschneidungen der Datensätze erfolgt die eigentliche Datenintegration. Zur Umsetzung des Modells wurden drei Python-Skripte erarbeitet, welche alle notwendigen Vorverarbeitungsschritte und anschließenden Modellberechnungen automatisiert durchführen. Zusätzlich zur Bestimmung des Nichtwohnnutzungsanteiles in den Gebäuden, fand eine Wohnung- und Bevölkerungsabschätzung mittels gebäudetypischer Kenngrößen auf Gebäudebasis statt. Mittels der Abschätzungsergebnisse ohne und mit OSM-Gewerbeinformationen, konnte eine Bewertung dieser Methode erfolgen. Eine Beurteilung der Qualität des Modells im Vergleich zur Realität benötigt geeignete Validierungsdaten. Diese wurden in Form von baublockbezogenen statistischen Einwohner- und Wohnungszahlen von der Stadt Dresden bereitgestellt und zur Ergebnisdiskussion herangezogen. Regionale Unterschiede konnten anhand von Übersichts- und Detailkarten sowie statistischen Analysen herausgearbeitet werden. / Building data with information of building uses and building types play an important role for city-based settlement structure analyses. The estimation of demographic and socio-economic parameters is based on this data. They were used in the field of settlement development or in infrastructure planning. The availability of area-wide and small-scale data of building uses from surveying authorities is limited. For this reason, the estimation of population based on this data cannot be realised sufficiently. Therefore, it was the aim of this research paper to analyse the integration of user-generated geodata from OpenStreetMap (OSM)-project for estimating building-based population and housing units. The research focuses on the separation of residential and non-residential usage within buildings. Not being detected in official geodatasets, the information can be retrieved from OSM-point and polygondata. The development of a model for the integration of non-residential information from OSM is the main subject of this research. It contains the analyses of commercial information out of the OSM Tags. Besides an appropriate typology specifications are necessary to process multiple businesses within one official building. The actual data integration occurs with the help of spatial intersections between the datasets. The implementation of the model is based on three Python-scripts, executing all pre-processing and following calculation steps automatically. In addition to the identification of non-residential building-parts, an estimation of population and housing units per building, based on typical building parameters took place. By means of the estimation results with and without OSM-information it was possible to valuate this method. Validation data is necessary to measure the quality of the model in comparison to reality. This datasets was provided by the City of Dresden, consisting of statistical population and building unit numbers based on building blocks, and used for the discussion of the results. To describe regional differences, maps with overview and detailed scales as well as statistical schemata where used.

Use and misuse of quantitative and graphical Information in Statistics An Approach in Teaching

Carter, Lucette, Hardouin, Cécile 12 April 2012 (has links) (PDF)
Miscellaneous examples of misleading statistical data or interpretation are presented in a form suitable for students in mathematics or Social Sciences during a first course of statistics. The aim is to promote critical thinking when confronted (mainly by the media or scientific papers) by information that is biased, incomplete, poorly defined, or deliberately oriented towards a preconceived target. Starting with the simple manipulation of Simpson paradox, the emphasis is put on the need for counfounding in the analysis of relationship between variables.

Managing diverse teams by enhancing team identification: The mediating role of perceived diversity

Shemla, Meir, Wegge, Jürgen 22 July 2020 (has links)
Although diversity provides a greater pool of knowledge and perspectives, teams often do not realize the potential offered by these additional informational resources. In this study, we develop a new model seeking to explain when and how teams that are diverse in terms of educational background utilize the afforded informational variety by engaging in deeper elaboration of task-relevant information. We found that collective team identification moderated the relationship between educational team diversity and elaboration of task-relevant information, such that under high (low) levels of team identification, educational diversity was positively (negatively) related to information elaboration. As expected, this moderating effect was shown to be mediated simultaneously through two different types of perceived team diversity. We found that the negative path was mediated through a perceived diversity measure reflecting a split into subgroups, whereas the positive path was mediated through a perceived diversity measure reflecting perceived educational heterogeneity. Taken together, this study contributes to the team diversity literature by shedding light on the important role of collective team identification in unlocking the potential of objective educational team diversity, by uncovering the underlying mechanisms accounting for this effect, and by demonstrating the usefulness of distinguishing between different types of perceived diversity.

From disclosure overload to decision-useful information: Quality of disclosure in voluntary reporting

Winter, Sophie 20 May 2021 (has links)
As a result of new information technology and globalization, there has never before been a time when people have had better access to information, than nowadays. The potential overload of information builds the basis for the research questions of this cumulative dissertation, which relates to the extensively discussed 'disclosure overload problem'. Special focus is put on decision-useful information in voluntary reporting of capital market-oriented companies. In this context the first manuscript investigates the quality of information in voluntary strategy reporting and formulates qualitative principles. Based thereon, the second manuscript examines determinants influencing the quality of strategy reporting. The third manuscript is focusing on Corporate Social Responsibility (CSR) reporting and investigates the relation of transparency in CSR reports and external assurance. The prior discussed topics as well as financial reporting and new reporting concepts, like integrated reporting, are put into context in the fourth manuscript. In this educational case study special emphasis is placed on the determination of material information, which is of high importance for future decision leaders.

Trustworthiness of voice-based assistants: Integrating interlocutor and intermediary predictors

Weidmüller, Lisa, Etzrodt, Katrin, Engesser, Sven 01 March 2024 (has links)
When intelligent voice-based assistants (VBAs) present news, they simultaneously act as interlocutors and intermediaries, enabling direct and mediated communication. Hence, this study discusses and investigates empirically how interlocutor and intermediary predictors affect an assessment that is relevant for both: trustworthiness. We conducted a secondary analysis using data from two online surveys in which participants (N = 1288) had seven quasi-interactions with either Alexa or Google Assistant and calculated hierarchical regression analyses. Results show that (1) interlocutor and intermediary predictors influence people’s trustworthiness assessments when VBAs act as news presenters, and (2) that different trustworthiness dimensions are affected differently: The intermediary predictors (information credibility; company reputation) were more important for the cognition-based trustworthiness dimensions integrity and competence. In contrast, intermediary and interlocutor predictors (ontological classification; source attribution) were almost equally important for the affect-based trustworthiness dimension benevolence.

The Role of Visual and Auditory Information in the Perception of Complex Skills in Gymnastics

Veit, Frederike 17 July 2023 (has links)
The perception of our environment and processing situation- or task-relevant information guides us through our everyday life. For example, in sports, the perception of situation-relevant information can be crucial for success or defeat. Different studies show that auditory and visual information interacts in the perception of complex stimuli (Allerdissen et al., 2017; Ca˜nal-Bruland et al., 2018). Furthermore, the combination of auditory and visual stimuli seems to lead to an increase in the precision of perception (Effenberg, 2005). So far, many studies have investigated the influence of (motor) experiences on the perception and evaluation of complex skills (Heinen et al., 2012; Pizzera & Raab, 2012). This dissertation investigates the role of visual and auditory information in the perception, assessment, and evaluation of complex gymnastic skills. Furthermore, it attempts to approach the role of auditory and visual information in motor control of complex skills. The publication-based dissertation includes five different studies. The first two studies (chapters four and five) deal with expert-novice comparisons regarding the quality of movement perception in gymnastics under three different conditions (audiovisual, visual, and auditory). Here, a three-part acrobatic element sequence (round-off, followed by a back handspring and straight back somersault) on the floor was chosen as the object of investigation. Based on the results of the first study, the second investigation takes up the three-part acrobatic series again. The focus here is on the auditory perception of the natural movement sounds through manipulations. The results of the second study lay the foundation for subsequent investigations. The third study investigated whether and to what extent auditory and visual information processing affect the execution of complex skills in trampoline gymnastics. The fourth study takes up the acrobatic series again. Here, music is examined as a possible influencing factor that can play an essential role in female gymnastics on the floor. The fifth and final study attempts to replicate the results of the fourth study for another component of floor routines in female gymnastics female (gymnastic series). Within the dissertation project studies, previous study results regarding the perception of complex skills could be confirmed for the field of gymnastics. On the one hand, it could be shown that more accurate estimations of complex skills are made when visual and auditory information is available and that current gymnasts use auditory information differently than persons without previous experience and persons with visual experience. On the other hand, it could be shown within a synchronization task in trampoline gymnastics that the availability of information affects the speed of movement regulation. It could also be observed that music adapted to the speed of movement leads to higher scores in evaluating the shown gymnastics skills.:Versicherung I List of Publications II Summary III Zusammenfassung IV 1 Introduction 2 Theoretical Background 2.1 Motion Perception in Gymnastics 2.2 Sensory Contributions to Motion Perception 2.3 Neurophysiological Processes in Motion Perception 2.4 Behavioral and Cognitive Approaches to Motion Perception 2.5 Summary 3 Research Program 4 Publication I - The Role of Visual and Auditory Information in the Observation and Evaluation of Complex Skills in Gymnastics 5 Publication II - How does Auditory Information Influence Observers’ Perception during the Evaluation of Complex Skills? 6 Publication III (accepted) - The Role of Auditory and Visual Information in Interpersonal Coordination in Trampoline Gymnastics 7 Publication IV - Does Jumping to the Beat Result in Better Ratings from Gymnastics Experts? 8 Publication V - The Influence of Music on Judges’ Evaluation of Complex Skills in Gymnastics 9 General Discussion 9.1 Theoretical Discussion 9.2 Methodological Discussion 9.3 Practical Implications 10 Conclusions References Appendix / Die Wahrnehmung unserer Umwelt und die Verarbeitung der situations- oder auf- gabenrelevanten Informationen leitet uns durch unseren Alltag. Im Sport kann die Wahrnehmung von situationsrelevanten Informationen ausschlaggebend für Erfolg oder Niederlage sein. Dabei zeigen unterschiedliche Studien, dass auditive und visuelle Informationen bei der Wahrnehmung komplexer Stimuli interagieren (Allerdissen et al., 2017; Cañal-Bruland et al., 2018). Des Weiteren scheint die Kombination von auditiven und visuellen Reizen zu einer präziseren Wahrnehmung zu führen (Effenberg, 2005). Bisher wurde vielfach untersucht, welchen Einfluss (Bewegungs-) Erfahrungen auf die Wahrnehmung und die Bewertung von Bewegungen hat (Heinen et al., 2012; Pizzera & Raab, 2012). Das Ziel des Dissertationsprojektes ist es die Rolle von visuellen und auditiven Informationen bei der Wahrnehmung, Einschätzung und Bewertung von komplexen turnerischen Elementen zu untersuchen. Des Weiteren wird versucht sich der Rolle von auditiven und visuellen Informationen bei der motorischen Kontrolle komplexer Bewegungen zu nähern. Die publikationsbasierte Arbeit umfasst fünf Studien. Die ersten beiden Untersuchungen (Kapitel vier und fünf) befassen sich mit Experten-Novizen-Vergleichen hinsichtlich der Qualität der Bewegungswahrnehmung im Gerätturnen unter drei verschiedenen Bedingungen (audio-visuell, visuell, auditiv). Hierbei wurde eine dreiteilige akrobatische Elementabfolge (Rondat, Flick-Flack, Salto rückwärts gestreckt) am Gerät Boden als Untersuchungsgegenstand gewählt. Aufbauend auf den Ergebnissen der ersten Studie greift die zweite Untersuchung die dreiteilige Bewegungsfolge erneut auf. Der Fokus wird hierbei auf die natürlichen Bewegungsgeräusche gelegt, deren Informationen durch Manipulationen verändert werden. Die Ergebnisse der zweiten Studie legen die Grundlage für die darauf folgenden Untersuchungen. In der dritten Studie wurde untersucht, ob und inwiefern sich die Verarbeitung von auditiven und visuellen Informationen auf die Ausführung von komplexen Bewegungen auswirkt. Die vierte Studie greift erneut die akrobatische Elementabfolge auf. Hierbei wird Musik als möglicher Einflussfaktor untersucht, der im Gerätturnen weiblich am Boden eine wichtige Rollen spielen kann. Die fünfte und abschließende Studie versucht die Ergebnisse der vierten Studie für einen anderen Bestandteil der Bodenübung im Gerätturnen weiblich (gymnastische Reihen) zu replizieren. Innerhalb des Dissertationsprojektes konnten bisherige Studienergebnisse bezüglich der Wahrnehmung von komplexen Bewegungen für den Bereich des Turnens bestätigt werden. Einerseits konnte gezeigt werden, dass genauere Einschätzungen von Bewegungen erfolgen, wenn visuelle und auditive Informationen verfügbar sind und aktive Sportler:innen auditive Informationen anders nutzen, als Personen ohne Vorerfahrung oder mit visuellen Erfahrungen. Andererseits konnte innerhalb einer Synchronisationsaufgabe im Trampolinturnen gezeigt werden, dass sich die Verfügbarkeit der Informationen auf die Geschwindigkeit der Bewegungsregulation auswirkt. Es konnte außer- dem beobachtet werden, dass an die Bewegungsgeschwindigkeit angepasste Musik zu höheren Werten bei der Bewertung der gezeigten Bewegungen führt.:Versicherung I List of Publications II Summary III Zusammenfassung IV 1 Introduction 2 Theoretical Background 2.1 Motion Perception in Gymnastics 2.2 Sensory Contributions to Motion Perception 2.3 Neurophysiological Processes in Motion Perception 2.4 Behavioral and Cognitive Approaches to Motion Perception 2.5 Summary 3 Research Program 4 Publication I - The Role of Visual and Auditory Information in the Observation and Evaluation of Complex Skills in Gymnastics 5 Publication II - How does Auditory Information Influence Observers’ Perception during the Evaluation of Complex Skills? 6 Publication III (accepted) - The Role of Auditory and Visual Information in Interpersonal Coordination in Trampoline Gymnastics 7 Publication IV - Does Jumping to the Beat Result in Better Ratings from Gymnastics Experts? 8 Publication V - The Influence of Music on Judges’ Evaluation of Complex Skills in Gymnastics 9 General Discussion 9.1 Theoretical Discussion 9.2 Methodological Discussion 9.3 Practical Implications 10 Conclusions References Appendix

Understanding local and scientific knowledge about flooding adaptations in low-lying areas of Central Vietnam

Tran, Huynh Bao Chau, Ubukata, Fumikazu 29 December 2021 (has links)
This research focuses on clarifying the local and scientific knowledge about flooding adaptations, the interaction between local knowledge and scientific information in the low-lying area of Central Vietnam is analyzed. Data was obtained using three techniques including: semi-structured interviews, direct observation and household surveys. Responses indicate that the villagers have accumulated and inherited this type of knowledge in their society for a long time. The level of local knowledge is affected by gender, occupation and house location. This implies that the villagers’ social roles and their everyday interactions with the natural environment have nurtured an accumulated local knowledge. Scientific information is provided by the National Committee for Flood and Storm Control and National Center for Hydrometeorology Prediction. It contains information regarding disaster type, intensity, risk level and directions. The information is transferred to local people through mass media, social networks and official documents. However, local people are credulous toward scientific information given by the state. It was found that many villagers are not likely to follow the official guideline, especially the villagers with a high level of local knowledge. / Nghiên cứu tập trung làm rõ kiến thức bản địa và khoa học về thích ứng lũ lụt cũng như mối tương tác của chúng ở vùng trũng thấp miền Trung Việt Nam. Dữ liệu được thu thập bằng cách sử dụng kết hợp ba phương pháp bao gồm phỏng vấn bán cấu trúc, quan sát trực tiếp và khảo sát hộ gia đình. Các kết quả nghiên cứu chỉ ra rằng người dân đã tích lũy và kế thừa kiến thức bản địa từ xã hội của họ trong một thời gian dài. Mức độ kiến thức bản địa bị ảnh hưởng bởi giới tính, nghề nghiệp và vị trí nhà ở. Vai trò xã hội và những tương tác hàng ngày của người dân với môi trường tự nhiên đã nuôi dưỡng và tích lũy kiến thức bản địa. Thông tin khoa học được cung cấp bởi Ủy ban Phòng chống lụt bão Quốc gia và Trung tâm Dự báo Khí tượng Thủy văn Quốc gia. Các thông tin về loại thiên tai, cường độ, mức độ rủi ro và hướng chỉ dẫn được thông báo. Thông tin này được chuyển đến người dân thông qua các phương tiện thông tin đại chúng, mạng xã hội và các văn bản chính thức. Tuy nhiên, người dân địa phương chủ quan trước những thông tin khoa học do cơ quan nhà nước đưa ra. Nhiều người dân không tuân theo các hướng dẫn chính thức của chính quyền địa phương, đặc biệt là những người có mức độ kiến thức bản địa được đánh giá cao.

Reproducible measurable residual disease detection by multiparametric flow cytometry in acute myeloid leukemia

Röhnert, Maximilian A., Kramer, Michael, Schadt, Jonas, Ensel, Philipp, Thiede, Christian, Krause, Stefan W., Bücklein, Veit, Hoffmann, Jörg, Jaramillo, Sonia, Schlenk, Richard F., Röllig, Christoph, Bornhäuser, Martin, McCarthy, Nicholas, Freeman, Sylvie, Oelschlägel, Uta, Bonin, Malte von 21 May 2024 (has links)
Measurable residual disease (MRD) detected by multiparametric flow cytometry (MFC) is associated with unfavorable outcome in patients with AML. A simple, broadly applicable eight-color panel was implemented and analyzed utilizing a hierarchical gating strategy with fixed gates to develop a clear-cut LAIP-based DfN approach. In total, 32 subpopulations with aberrant phenotypes with/without expression of markers of immaturity were monitored in 246 AML patients after completion of induction chemotherapy. Reference values were established utilizing 90 leukemia-free controls. Overall, 73% of patients achieved a response by cytomorphology. In responders, the overall survival was shorter for MRDpos patients (HR 3.8, p = 0.006). Overall survival of MRDneg non-responders was comparable to MRDneg responders. The inter-rater-reliability for MRD detection was high with a Krippendorffs α of 0.860. The mean time requirement for MRD analyses at follow-up was very short with 04:31 minutes. The proposed one-tube MFC approach for detection of MRD allows a high level of standardization leading to a promising inter-observer-reliability with a fast turnover. MRD defined by this strategy provides relevant prognostic information and establishes aberrancies outside of cell populations with markers of immaturity as an independent risk feature. Our results imply that this strategy may provide the base for multicentric immunophenotypic MRD assessment.

'The sight of sound': Gebärdensprachdolmetschen auf der lautsprachlichen Theaterbühne am Beispiel einer gedolmetschten Aufführung von 'My fair lady' am Hans Otto Theater Potsdam

Hildebrandt, Mandy 02 June 2016 (has links)
Während die Verdolmetschung lautsprachlicher Theateraufführungen in die Gebärdensprache in vielen Ländern selbstverständlich und regelmäßig angeboten wird, handelt es sich in Deutschland dabei noch um Einzelerscheinungen. Eine Ausnahme stellt das Hans Otto Theater Potsdam dar, das seit 1996 regelmäßig gedolmetschte Aufführungen anbietet und dabei die Methode des Shadow Interpreting nutzt. Am Beispiel einer gedolmetschten Aufführung von „My Fair Lady“ am Hans Otto Theater werden in dieser Arbeit folgende Aspekte der gebärdensprachlichen Verdolmetschung von Theateraufführungen untersucht: Stückauswahl, Dolmetscheranzahl und Rollenverteilung, Auswahl und Einführung von Namensgebärden der Figuren, Positionierung der Dolmetscher, Rollendarstellung und Rollenwechsel, Übertragung der akustischen Ebene des Aufführungstextes (linguistische und paralinguistische Informationen, Musik, Geräusche), äußere Erscheinung der Dolmetscher, Beleuchtung der Dolmetscher und die Inkorporation der Dolmetscher in die Aufgabe.
