Full textHydrogeologische Modellierung ist von erheblicher Unsicherheit geprägt. Überparametrisierte Modelle erhöhen die Unsicherheit, da gemessene Informationen auf alle Parameter verteilt sind. Die vorliegende Arbeit schlägt einen neuen Ansatz vor, um diese Unsicherheit zu reduzieren. Eine Möglichkeit, um dieses Ziel zu erreichen, besteht darin, ein Modell auszuwählen, das ein gutes Ergebnis mit möglichst wenigen Parametern liefert („parsimonious model“), und es zu kalibrieren, indem viele Informationsquellen genutzt werden. Das 1973 von Hirotugu Akaike vorgeschlagene Informationskriterium, bekannt als Akaike-Informationskriterium (engl. Akaike’s Information Criterion; AIC), ist ein statistisches Wahrscheinlichkeitskriterium basierend auf der Informationstheorie, welches die Auswahl eines Modells mit möglichst wenigen Parametern erlaubt. AIC formuliert das Problem der Entscheidung für ein gering parametrisiertes Modell als ein modellübergreifendes Optimierungsproblem. Die Anwendung von AIC in der Grundwassermodellierung ist relativ neu und stellt eine Herausforderung in der Anwendung verschiedener Messquellen dar. In der vorliegenden Dissertation werden maßgebliche Forschungsergebnisse in der Anwendung des AIC in hydrogeologischer Modellierung unter Anwendung unterschiedlicher Messquellen diskutiert. AIC wird an Grundwassermodellen getestet, bei denen drei synthetische Datensätze angewendet werden: Wasserstand, horizontale hydraulische Leitfähigkeit und Tracer-Konzentration. Die vorliegende Arbeit analysiert den Einfluss folgender Faktoren: Anzahl der Messungen, Arten der Messungen und Reihenfolge der kalibrierten Parameter. Diese Analysen machen nicht nur deutlich, dass die Anzahl der gemessenen Parameter die Komplexität eines Modells bestimmt, sondern auch, dass seine Diversität weitere Komplexität für gering parametrisierte Modelle erlaubt. Allerdings konnte ein solches Modell nur erreicht werden, wenn eine bestimmte Reihenfolge der kalibrierten Parameter berücksichtigt wurde. Folglich sollten zuerst jene Parameter in Betracht gezogen werden, die deutliche Verbesserungen in der Modellanpassung liefern. Der Ansatz, ein gering parametrisiertes Modell durch die Anwendung des AIC mit unterschiedlichen Informationsarten zu erhalten, wurde erfolgreich auf einen Lysimeterstandort übertragen. Dabei wurden zwei unterschiedliche reale Messwertarten genutzt: Evapotranspiration und Sickerwasser. Mit Hilfe dieser weiteren, unabhängigen Modellbewertung konnte die Gültigkeit dieses AIC-Ansatzes gezeigt werden

Full textNeurodegenerative diseases, such as Alzheimer’s disease (AD) and Charcot Marie Tooth (CMT), are complex diseases. Their pathological mechanisms are still not well understood, and the progress in the research and development of new potential disease-modifying therapies is slow. Categorical data like rating scales and Genome-Wide Association Studies (GWAS) data are widely utilized in the neurodegenerative diseases in the diagnosis, prediction and progression monitor. It is important to understand and interpret these data correctly if we want to improve the disease research. The purpose of this thesis is to use the modern psychometric Item Response Theory to analyze these categorical data for better understanding the neurodegenerative diseases and facilitating the corresponding drug research. First, we applied the Rasch analysis in order to assess the validity of the Charcot-Marie-Tooth Neuropathy Score (CMTNS), a main endpoint for the CMT disease clinical trials. We then adapted the Rasch model to the analysis of genetic associations and used to identify genes associated with Alzheimer’s disease by summarizing the categorical genotypes of several genetic markers such as Single Nucleotide Polymorphisms (SNPs) into one genetic score. Finally, to select sensitive items in the most used psychometrical tests for Alzheimer’s disease, we calculated the mutual information based on the item response model to evaluate the sensitivity of each item on the ADAS-cog scale

Full textMaskininlärningsmodeller utvärderas vanligtvis med mätvärden så som noggrannhet, förväxlingsmatris, återkallelse. Dessa mätvärden ger varken information om kvaliteten på modellerna eller svårighetsgraden för de testdata som används för att utvärdera modellerna. Utan denna information kan ingen tillförlitlig jämförelse göras mellan olika test data och/eller olika modeller. Vissa av de tidigare nämnda begränsningarna avseende de aktuella utvärderingsmetoderna i maskininlärning kan övervinnas genom att applicera Item respons teori. Item respons teori är ett psykometriskt ramverk som används för att samtidigt uppskatta förmågan av en student och svårighetsgraden för en test. Detta ramverk möjliggör jämförelse av test data med hjälp av dess svårighetsgrad och jämförelse av studenterna med hjälp av deras respektive förmåga. Denna uppsats fokuserar på möjliga tillämpningar av item response teori i maskininlärning och specifikt dess tillämpningar för klassificering av musikgenren. Närmare bestämt görs en fallstudieanalys av GTZAN-musikdata. GTZAN har dokumenterats innehålla många brister, till exempel det faktum att många artister ofta förekommer i samma genre kategori. Därför görs en kontrollstudie av GTZAN-data, där en grupp klassificerare tränas med slumpmässigt stratifierade data och den andra gruppen tränas med data där träningsdata och testdata inte har låtar från en gemensam artist. Svarmönstren från dessa två grupper av klassificerare analyseras med hjälp av item response teori.

Full textWhen making decisions about what to do in a disaster, people consider the welfare of their animals. Most people consider their pets to be "part of the family." There are more than 144 million pet dogs and cats in homes around the US, and Colorado is home to a $3 billion livestock industry. In emergency response, supporting the human-animal bond is one important way we can assist people in making good decisions about evacuation, and improve their ability to recover after the emergency period is over. There is an opportunity to leverage social computing tools to support the information needs of people concerned with animals in disasters. This research uses three major studies to examine the information management and cooperative work done around animals in this domain: First, an online study of the response of animal advocates in the 2012 Hurricane Sandy event; second, a study bridging the online and offline response of equine experts following the 2013 Colorado floods; and third, an extended 22-month ethnographic study of the work done at animal evacuation sites, beginning with on-the-ground participant observation at two fairground evacuation sites during the Black Forest Fire in Southern Colorado in 2013, and including the design of two information support tools. The research provides lessons about how information online, information offline, and the bridging of information in those arenas both supports and limits the potential for innovation in addressing the unusual and emergent ill-structured problems that are hallmarks of disaster response. The role of expertise as a vital resource in emergency response, and recommendations for policy improvements that appreciate the conscious inclusion of spontaneous volunteers are two contributions from this work.

Full textIn this master thesis, computer science curriculum in compulsory school of Lithuania and other foreign countries are reviewed. Data of "Beaver" information technology contest, which is organized in more than ten countries, has been selected as a more attractive way to imlement this study. The comparisons of tasks sets in Lithuanian “Beaver” competition in 2008 – 2010 according to informatics concepts are presented. In this thesis, there was assessed information function of tasks set by using data of pupils’ results. The data of results were obtained from Lithuanian competition of “Beaver” in 2010. Information function allows choosing the best tasks for due ability level of pupils. Pupils’ abilities level of computer science is inseparable from informatics fundamentals, which is forming over time when pupils get the right information about informatics fundamentals during the computers science lesson, or when their teachers use information and communication technologies. The difficulty parameters of tasks, and discriminations parameters of tasks, which describe how well an item can differentiate between examinees having abilities below the item location and those having abilities above the item location, are calculated. The results of this study are important for teachers, which influence formation of informatics fundamentals of pupils, as well as for experts and creators of competition tasks, because for them it is important the right and purposeful introduction to computer...

Full textComputerized Adaptive Testing (CAT) based on Item Response Theory allows more accurate assessments with fewer questions than the classic paper test. Nonetheless, the CAT building involves some key questions that, when done properly, can further improve the accuracy and efficiency in estimating examinees\' abilities. One of the main questions is in regard to choosing the Item Selection Rule (ISR). The classic CAT makes exclusive use of one ISR. However, these rules have differences depending on the examinees\' ability level and on the CAT stage. Thus, the objective of this work is to reduce the dichotomous - which considers only correct and incorrect answers - test size which is inserted on a classic CAT without significant loss of accuracy in the estimation of the examinee\'s ability level. For this purpose, we create the ALICAT approach that personalizes the item selection process in a CAT considering the use of more than one ISR. To apply this approach, we first analyze the performance of different ISRs. The case study in textit test of the ENEM 2012 shows that the Kullback-Leibler Information with a Posterior Distribution (KLP) has better performance in the examinees\' ability estimation when compared with: Fisher Information (F); Kullback-Leibler Information (KL); Maximum Likelihood Weighted Information(MLWI); and Maximum Posterior Weighted Information (MPWI) rules. Previous results in the literature show that CAT using KLP was able to reduce this test size by 46.6% from the full size of 45 items with no significant loss of accuracy in estimating the examinees\' ability level. In this work, we observe that the F and the MLWI rules performed better on early CAT stages to estimate examinees proficiency level with extreme negative and positive values, respectively. With this information, we were able to reduce the same test by 53.3% using an approach that uses the best rules together

Full textNo romance A defesa Lujin, de Vladimir Nabokov, publicado em russo em 1930, o texto procura levar o leitor a adotar processos mentais similares ao de um jogador de xadrez e de um esquizofrênico, características do personagem-título do romance. Delineiam-se as expectativas e circunstâncias de um ser de papel que se vê jogando um xadrez em que também é peça e traçam-se paralelos com as expectativas e circunstâncias do leitor perante esse texto literário. O prefácio de Nabokov à edição em inglês de 1964 é tomado como indício de um leitor e um autor implícitos que ele procura moldar. Para análise dos elementos textuais e níveis de abstração mental envolvidos, recorre-se à estética da recepção de Wolfgang Iser e a diversas ideias do psiquiatra e etnólogo Gregory Bateson, entre elas o conceito de duplo vínculo, com atenção às distinções entre mapa/território e play/game. Um duplo duplo vínculo é perpetrado na interação leitor-texto: 1) o leitor é convidado a sentir empatia pela situação do personagem Lujin e a considerá-lo lúcido e louco ao mesmo tempo; e 2) o leitor é colocado como uma instância pseudo-transcendental incapaz de comunicação com a instância inferior (Lujin), gerando uma angústia diretamente relacionável ao seu envolvimento com a ficção, replicando de certa forma a loucura de Lujin. A sinestesia do personagem Lujin é identificada como um dos elementos do texto capaz de recriar a experiência de jogar xadrez até para quem não aprecia o jogo. Analisa-se a conexão entre a esquizofrenia ficcional do personagem Lujin e a visão batesoniana do alcoolismo
In Vladimir Nabokovs novel, The Luzhin Defense, published in Russian in 1930, the text beckons the reader on to adopt mental processes similar to a chess players and a schizophrenic persons both traits of the novels title character. This character sees himself both as player and piece of an ongoing game of chess; his expectations and predicaments are traced in parallel to the readers own as he or she navigates the text. Nabokovs preface to the 1964 English edition is taken as an indication that he tries to shape both an implicit reader and an implicit author. In order to analyze the elements of the text and degrees of mental abstraction involved in this, we refer to Wolfgang Isers reader-response theory and also many of psychiatrist and ethnologist Gregory Batesons ideas, such as the double bind, with special regard to map vs. territory and play vs. game distinctions. A double double bind is built within the reader-text interplay as follows: 1) the reader is invited to feel empathy for Luzhins predicament and to regard him at once as sane and insane; and 2) the reader is posited as a pseudo-transcendental instance unable to communicate with his nether instance (Luzhin) in such a way that it brews a feeling of anxiety directly relatable to his or her engagement in the work of fiction, reproducing, in a way, Luzhins madness. Luzhins synesthesia is identified as one of the text elements with the ability to recreate the chess-playing experience even to readers who are not fond of the game. The connection between Luzhins fictional schizophrenia and Batesons views on alcoholism is analyzed

Sin embargo, cuando los agentes involucrados en una tarea de PMA son racionales y auto-interesados, el objetivo último es obtener un plan conjunto que resuelva las tareas locales de los agentes y satisfaga sus intereses privados. De entre los distintos escenarios de PMA que involucran agentes auto-interesados, la PMA no cooperativa se centra en problemas que presentan un conjunto de agentes no estrictamente competitivos con intereses comunes y conflictivos. En este contexto, pueden surgir conflictos cuando los agentes ponen en común sus planes y la combinación resultante provoca que algunos de estos planes no sean ejecutables, lo que implica una pérdida de utilidad para los agentes afectados. Cada participante desea ejecutar su plan tal como fue concebido, pero las congestiones y conflictos que pueden surgir entre las acciones de los diferentes planes fuerzan a los agentes a obtener una solución estable y coordinada. Las tareas de PMA no cooperativa se abordan a través de juegos no cooperativos, cuyo objetivo es hallar un plan conjunto estable (equilibrio) que asegure que los planes de los agentes sean ejecutables (resolviendo los conflictos de planificación) al tiempo que los agentes satisfacen sus intereses privados en la medida de lo posible. Aunque este paradigma refleja muchos problemas de la vida real, existen pocos enfoques computacionales para PMA no cooperativa en la literatura. Esta tesis doctoral estudia el uso de juegos no cooperativos para resolver tareas de PMA no cooperativa con agentes racionales auto-interesados. Cada agente calcula un plan para su tarea de planificación y posteriormente, los participantes intentan ejecutar sus planes en un entorno compartido. Abordamos la PMA no cooperativa desde una doble perspectiva. Por una parte, nos centramos en la satisfacción de los agentes estudiando las propiedades deseables de soluciones estables, tales como la optimalidad y la justicia. Por otra parte, buscamos una combinación de PMA y técnicas de teoría de juegos capaz de calcular planes conjuntos estables de forma eficiente al tiempo que se minimiza la complejidad computacional de esta tarea combinada. Además, consideramos los conflictos de planificación y congestiones en las funciones de utilidad de los agentes, lo que resulta en un enfoque más realista. Bajo nuestro punto de vista, esta tesis doctoral abre una nueva línea de investigación en PMA no cooperativa y establece los principios básicos para resolver el problema de la generación de planes conjuntos estables para agentes de planificación auto-interesados mediante la combinación de teoría de juegos y planificación automática.

Full textStorytelling has been identified as an effective marketing method, and many companies have mastered the art of telling stories. Storytelling is used to create an emotional response among the intended audience, and if companies can successfully do this, it can be a way of differentiating themselves. The method has long been emphasized as the key to success, but is this the whole truth? Therefore, we want to answer; How does storytelling affect advertising effectiveness? The aim of the essay was to investigate, describe and discuss storytelling and its effects as a marketing method. The result of this study shows that storytelling is more efficient than traditional product-based advertising. However, there are differences in its effect on different product categories. According to the study, storytelling works better when the commitment to the product is low and when its purchase has a transformative or emotional enhancement. The result of the study leads to an increased understanding of when storytelling as a marketing method is effective.

Full textThe work presented extends and contributes to research in error-control coding and information theory. The work focuses on the construction of block codes using an IIR lter structure. Although previous works in this area uses FIR lter structures for error-detection, it was inherently used in conjunction with other error-control codes, there has not been an investigation into using IIR lter structures to create codewords, let alone to justify its validity. In the research presented, linear block codes are created using IIR lters, and the error-correcting capabilities are investigated. The construction of short codes that achieve the Griesmer bound are shown. The potential to construct long codes are discussed and how the construction is constrained due to high computational complexity is shown. The G-matrices for these codes are also obtained from a computer search, which is shown to not have a Quasi-Cyclic structure, and these codewords have been tested to show that they are not cyclic. Further analysis has shown that IIR lter structures implements truncated cyclic codes, which are shown to be implementable using an FIR lter. The research also shows that the codewords created from IIR lter structures are valid by decoding using an existing iterative soft-decision decoder. This represents a unique and valuable contribution to the eld of error-control coding and information theory.

Full textHydrogeologische Modellierung ist von erheblicher Unsicherheit geprägt. Überparametrisierte Modelle erhöhen die Unsicherheit, da gemessene Informationen auf alle Parameter verteilt sind. Die vorliegende Arbeit schlägt einen neuen Ansatz vor, um diese Unsicherheit zu reduzieren. Eine Möglichkeit, um dieses Ziel zu erreichen, besteht darin, ein Modell auszuwählen, das ein gutes Ergebnis mit möglichst wenigen Parametern liefert („parsimonious model“), und es zu kalibrieren, indem viele Informationsquellen genutzt werden. Das 1973 von Hirotugu Akaike vorgeschlagene Informationskriterium, bekannt als Akaike-Informationskriterium (engl. Akaike’s Information Criterion; AIC), ist ein statistisches Wahrscheinlichkeitskriterium basierend auf der Informationstheorie, welches die Auswahl eines Modells mit möglichst wenigen Parametern erlaubt. AIC formuliert das Problem der Entscheidung für ein gering parametrisiertes Modell als ein modellübergreifendes Optimierungsproblem. Die Anwendung von AIC in der Grundwassermodellierung ist relativ neu und stellt eine Herausforderung in der Anwendung verschiedener Messquellen dar. In der vorliegenden Dissertation werden maßgebliche Forschungsergebnisse in der Anwendung des AIC in hydrogeologischer Modellierung unter Anwendung unterschiedlicher Messquellen diskutiert. AIC wird an Grundwassermodellen getestet, bei denen drei synthetische Datensätze angewendet werden: Wasserstand, horizontale hydraulische Leitfähigkeit und Tracer-Konzentration. Die vorliegende Arbeit analysiert den Einfluss folgender Faktoren: Anzahl der Messungen, Arten der Messungen und Reihenfolge der kalibrierten Parameter. Diese Analysen machen nicht nur deutlich, dass die Anzahl der gemessenen Parameter die Komplexität eines Modells bestimmt, sondern auch, dass seine Diversität weitere Komplexität für gering parametrisierte Modelle erlaubt. Allerdings konnte ein solches Modell nur erreicht werden, wenn eine bestimmte Reihenfolge der kalibrierten Parameter berücksichtigt wurde. Folglich sollten zuerst jene Parameter in Betracht gezogen werden, die deutliche Verbesserungen in der Modellanpassung liefern. Der Ansatz, ein gering parametrisiertes Modell durch die Anwendung des AIC mit unterschiedlichen Informationsarten zu erhalten, wurde erfolgreich auf einen Lysimeterstandort übertragen. Dabei wurden zwei unterschiedliche reale Messwertarten genutzt: Evapotranspiration und Sickerwasser. Mit Hilfe dieser weiteren, unabhängigen Modellbewertung konnte die Gültigkeit dieses AIC-Ansatzes gezeigt werden.

Full textENGLISH ABSTRACT: The purpose of the study was to investigate the controlled transfer of meaning that could be facilitated by the application of knowledge of sense-making theory. An object of communication, an advertisement, was consciously constructed on the basis of sense-making principles. An application of knowledge of sense making was then employed to assess the reception of the advertisement by a selected sample of respondents. The decision to select advertising as the choice of medium for the study stemmed from the increasing levels of criticism directed at this form of communication as a result of its frequent failure to deliver intended benefits for its sponsors. The intended benefits relate to the transfer of meaning that would prompt recipients of advertising messages to take an action that would be of value to the advertiser. More specific criticisms have centred on the failure of a growing number of advertising messages to deliver meaningful benefits as a result of their lack of relevance for the intended recipients of these communications. A call for a shift in mind-set away from traditional linear models currently employed to facilitate the design of advertising messages has prompted a growing recognition of the need to employ a more empathetic approach that would facilitate a positive interaction between an advertiser and a target audience. The emergence of what has been termed experiential marketing communications has advocated a view that advertising communications can promote stronger allegiances between organisations and their customers by the inclusion of meaningful sensory associations for recipients. This view, together with the insights revealed by those working in the field of sense making, suggested that the incorporation of sense-making theory could well accommodate the paradigm shift that has been called for in the design of advertising communications. The views and insights outlined above prompted the development of an advertisement that sought to incorporate sense-making theory into its construction. The requirement to allow for the transfer of intended meaning in the advertisement was facilitated by incorporating frames and cues, the design of which sought to assist in the resolution of equivocality and enable respondents to bridge cognitive gaps. The investigation took the form of an exploratory case study. The advertisement, constructed on the basis of sense-making theory, represented the control element of the study. In-depth interviews were conducted amongst grade 12 learners selected on the basis of their matching the target audience for which the advertisement had been designed. The semi-structured nature of the interviews followed a format that allowed for a comparison to be made between the intended input of meaning and the decoding of responses relating to the advertisement. Results indicated that there was a transfer of intended meanings incorporated into the advertisement as indicated in the decoded responses of respondents. These positive findings tend to indicate that a conscious application of sense-making theory to the construction of advertising messages could enhance their effectiveness.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die beheerde oordrag van betekenis, gefassiliteer deur die bepassing van kennis van die “sense-making” teorie, te ondersoek. ‘n Voorwerp van kommunikasie, ‘n advertensie, is doelbewus geskep op grond van die beginsels van die “sense-making” teorie. ‘n Toepassing van kennis van dié teorie is aangewend om die impak van die advertensie op ‘n steekproef van reagente te assesseer. Weens die voortdurende mislukking van die advertensie medium om beplande voordele aan die borge te lewer, styg vlakke van kritiek gerig tot hierdie medium. Juis hierdie statistiek het die besluit om die advertensie medium as voorwerp van studie te gebruik, laat ontwikkel. Die beplande voordele vir die borge hou direk verband met die oordrag van die betekenis wat die ontvanger van die advertensie boodskap sal aanpar om op te tree, en sodoende tot voordeel van die adverteerder sal strek. Kritiek is spesifiek gerig op die mislukking van al hoe meer advertensies wat nie betekenisvolle voordele lewer nie as gevolg van die irrelevansie van die vorm van kommunikasie vir die ontvanger. Die herkenning van die groeiende behoefde het ‘n beroep gemaak om ‘n paradigma skuif te maak, weg van die huidige, tradisionele, linêre model wat die ontwerp van advertensie boodskappe fassiliteer. Hierdie behoefte is om ‘n meer empatiese benadering in te stel, wat ‘n positiewe interaksie tussen die adverteerder en teiken gehoor sal fassiliteer. Die ontstaan van die sogenaamde “experietial marketing communications” het voorgestel dat die advertensie medium sterker getrouheid tussen organisasies en hul klante kan adverteer. Hierdie oogpunt, saam met die insig van dié gene wat in die veld van “sense making” werk, stel voor dat die inkorporasie van die “sense-making” teorie, wel die paradigma skuif, beroep op die ontwerp van die advertensie, kan akkommodeer. Dit het die ontwikkeling van ‘n advertensie met die “sense-making” teorie in sy konstruksie geïnkorporeer, aangewaldeer. Die vereiste om die oordrag van die beplande betekenis van ‘n advertensie te bewerkstellig, is gefassiliteer deur sketse en aanwysings te inkorporeer. Hierdie sketse en aanwysings is ontwerp om die voorkoming/oplossing van dubbelsinnigheid te ondersteun en om reagente te help om kognitiewe gapings te oorbrug. Die ondersoek het die vorm van ‘n ontdekkings gevallestudie aangeneem. Die advertensie, gebaseer op die “sense-making” teorie, het die kontrole element van die studie verteenwoordig. Onderhoude is indiepte gevoer met graad 12 leerders wat gekeur is op grond van die feit dat hulle in die teikengroep van die ontwerpte advertensie val. Die semigestruktureerde aard van die onderhoude het toegelaat dat die voorafbeplande blootstelling aan die betekenis vergelyk word met die dekodering van die terugvoering in verband met die advertensie. Resultate het gewys dat daar wel ‘n oordrag van die beplande, geïnkorporeerde betekenis in die advertensie plaas gevind het, wat bewys is in as ‘n dekodeerde reaksie van die reagent. Hierdie positiewe bevindings neig om te bewys dat ‘n bewuste aanwending van die “sensemaking” teorie tot die konstruksie van die advertensie wese die effektiewiteit van boodskappe verbeter.
