A Theory of Form as Temporal Referentiality

Smith, Eron F 01 January 2016 (has links)
This study proposes temporal referentiality—roughly defined as the orientation of substance in its temporal medium—as a theoretical and analytical framework for musical form. Operating on the principle of music as a temporally extended entity, this thesis explores the connections that occur between substance across its medium, suggests an additional interpretation of medium connections (temporality) in terms of language tense, and examines substance connections (referentiality) through different types of filtering. I also propose a means for visual and literary interpretation of temporal referentiality, depicting a network of substance relationships established over a piece’s timespace. Analysis of this type assumes a listener’s complete familiarity with the substance in its temporal boundaries. Visual representations portray the amount and strength of future- and past-oriented musical substance at a given point in time, including which sections are connected to one another (medium connection) and which variables or features of sameness are responsible for this connection (substance connection). Employing an analogy between orientation and tense, it also becomes feasible to construct a “model prose composition” with the same temporal referentiality as a piece of music. Finally, a system of filtering serves to isolate portions of medium and substance and to clarify what elements are responsible for the elusive concept of “sameness.” The possibilities for temporal reference analysis are applied to the first movements of Bartók’s Fourth String Quartet and Brahms’s Violin Concerto, as well as Bach’s Contrapunctus #9 from The Art of Fugue and the Variations movement of Webern’s Symphony op. 21.

Talk the walk : Empirical studies and data-driven methods for geographical natural language applications

Götze, Jana January 2016 (has links)
Finding the way in known and unknown city environments is a task that all pedestrians carry out regularly. Current technology allows the use of smart devices as aids that can give automatic verbal route directions on the basis of the pedestrian's current position. Many such systems only give route directions, but are unable to interact with the user to answer clarifications or understand other verbal input. Furthermore, they rely mainly on conveying the quantitative information that can be derived directly from geographic map representations: 'In 300 meters, turn into High Street'. However, humans are reasoning about space predominantly in a qualitative manner, and it is less cognitively demanding for them to understand route directions that express such qualitative information, such as 'At the church, turn left' or 'You will see a café'. This thesis addresses three challenges that an interactive wayfinding system faces in the context of natural language generation and understanding: in a given situation, it must decide on whether it is appropriate to give an instruction based on a relative direction, it must be able to select salient landmarks, and it must be able to resolve the user's references to objects. In order to address these challenges, this thesis takes a data-driven approach: data was collected in a large-scale city environment to derive decision-making models from pedestrians' behavior. As a representation for the geographical environment, all studies use the crowd-sourced Openstreetmap database. The thesis presents methodologies on how the geographical and language data can be utilized to derive models that can be incorporated into an automatic route direction system. / <p>QC 20160516</p>

Lung function and prevalence trends in asthma and COPD : the Obstructive Lung Disease in Northern Sweden Thesis XVI

Backman, Helena January 2016 (has links)
Background Asthma and chronic obstructive pulmonary disease (COPD) are common obstructive airway diseases with a substantial burden in terms of morbidity, mortality and costs. Smoking is the single most important risk factor for COPD, and is associated with incident asthma. It is important to know if the prevalence of asthma and COPD is increasing or decreasing in the population in order to effectively allocate health care resources. The definitions of these diseases have varied over time which makes it difficult to measure changes in prevalence. The preferred method is to estimate the prevalence with the same procedures and definitions based on cross-sectional population samples with identical age distributions in the same geographical area at different time points. Measurements of lung function (spirometry) are required to diagnose COPD, and spirometry is used to evaluate disease severity and progress of both asthma and COPD, where observed values are compared to reference values. The most commonly used reference values in Sweden are published during the mid 1980s, and there are few evaluations of how appropriate they are today based on Swedish population samples. The aim of the thesis was to estimate trends in the prevalence of asthma and COPD in relation to smoking habits, and to evaluate and estimate reference values for spirometry. Methods The project was based on population-based samples of adults from the Obstructive Lung Disease in Northern Sweden (OLIN) studies. Postal questionnaires were sent to large cohorts, recruited in 1992 (n=4851, 20-69 years), 1996 (n=7420, 20-74 years) and 2006 (n=6165, 20-69 years), respectively. The questionnaire included questions on respiratory symptoms and diseases, their comorbidities and several possible risk factors including smoking habits. Structured interviews and spirometry were performed in random samples of the responders to the 1992 and 2006 surveys, of which n=660 (in 1994) and n=623 (in 2009) were within identical age-spans (23-72 years). The trend in asthma prevalence was estimated by comparing the postal questionnaire surveys in 1996 and 2006, and the trend in COPD prevalence was estimated by comparing the samples participating in dynamic spirometry in 1994 and 2009, respectively. The prevalence of COPD was estimated based on two different definitions of COPD. Commonly used reference values for spirometry were evaluated based on randomly sampled healthy non-smokers defined in clinical examinations of participants in the 2006 postal questionnaire (n=501). The main focus of the evaluation was the global lung function initiative (GLI) reference values published in 2012, for which Z-scores and percent of predicted values were analysed. New sex-specific reference values for spirometry were estimated by linear regression, with age and height as predictors. These new OLIN reference values were also evaluated on a sample of healthy non-smokers identified in the population-based West Sweden Asthma Study. Results Although the prevalence of smoking decreased from 27.4% to 19.1%, p&lt;0.001, between 1996 and 2006, the prevalence of physician-diagnosed asthma increased from 9.4% to 11.6%, p&lt;0.001. The prevalence of symptoms common in asthma such as recurrent wheeze did not change significantly between the surveys or tended to decrease, while bronchitis symptoms such as cough and sputum production decreased significantly. The evaluation of the GLI reference values showed that the predicted values were significantly lower compared to the observed values in Norrbotten, which makes the percent of predicted too high. This was especially true for FVC percent predicted with a mean of 106%. In general, the deviations were more pronounced among women. New OLIN reference values valid for the Norrbotten sample were modelled and showed a high external validity when applied on the sample from western Sweden. The prevalence of moderate to severe COPD decreased substantially over the 15-year period between 1994 and 2009, regardless of definition. Conclusions In parallel with substantially decreased smoking habits in the population between 1996 and 2006, the prevalence of several airway symptoms decreased while the prevalence of physician-diagnosed asthma increased. These results suggest increased diagnostic activity for asthma, but may also suggest that the asthma prevalence has continued to increase. In contrast to asthma, the prevalence of COPD tended to decrease and moderate to severe COPD decreased substantially. The continuous decrease in smoking in Sweden during several decades prior to the study period is most likely contributing to these results. The evaluation of reference values showed that the GLI reference values were lower than the observed spirometric values in the population, especially for women, why the new up-to date reference values may be of importance for disease evaluation in epidemiology and in the health care as well.

From Translation to Navigation of Different Discourses: A Model of Search Term Selection during the Pre-Online Stage of the Search Process

Iivonen, Mirja, Sonnenwald, Diane H. 04 1900 (has links)
We propose a model of search term selection process based on our empirical study of professional searchers during the pre-online stage of the search process. The model characterizes the selection of search terms as the navigation of different discourses. Discourse refers to the way of talking and thinking about a certain topic; there often exists multiple, diverse discourses on the same topic. When selecting search terms, searchers appear to navigate a variety of discourses, i.e., they view the topic of a client's search request from the perspective of multiple discourse communities, and evaluate and synthesize differences and similarities among those discourses when selecting search terms. Six discourses emerged as sources of search terms in our study. These discourses are controlled vocabularies, documents and domains, the practice of indexing, clients' search requests, databases and the searchers' own search experience. Data further suggest that searchers navigate these discourses dynamically and have preferences for certain discourses. Conceptualizing the selection of search terms as a meeting place of different discourses provides new insights into the complex nature of the search term selection process. It emphasizes the multiplicity and complexity of the sources of search terms, the dynamic nature of the search term selection process, and the complex analysis and synthesis of differences and similarities among sources of search terms. It suggests that searchers may need to understand fundamental aspects of multiple discourses in order to select search terms.

The token-token identity-theory and recent theories of reference

Gjelsvik, Olav January 1986 (has links)
This thesis investigates a specific kind of criticism of the token-token identity-theory. This criticism is based on recent theories of reference. In the Introduction I argue that more than Davidson's three premisses is needed to establish that mental events are identical to physical events. One needs to invoke principles about what constitutes event-identity. In Part 1 I discuss event-identities. I lay down the constraints an adequate theory of event-identity must satisfy, and criticise the major theories in the literature. I suggest an alternative view, which I defend against some recent proposals. I end Part 1 by exploring a view which takes seriously the possibility of constitution-relations between events. In Parts 2 and 3 I discuss whether the identity-theory can be defended. Part 2 discusses sensations, and I concentrate on S. Kripke's arguments against the identity-view. I distinguish two versions of Kripke's argument, one epistemic, and one metaphysical. The epistemic version of the argument presupposes Kripke's views on content, but fails by its own standards. The metaphysical version is shown to be weak and implausible. Part 3 discusses cognitive events, and concentrates on de re beliefs. I produce an argument which apparently defeats the identity-view. I elaborate two main strategies in defence of the identity-theory. I argue that given a theory of de re beliefs or singular thoughts like G. Evans's, the theory of event-identities I have developed, and some plausible further premisses, the identity-theory seems to be defeated. A reasonable interpretation of this result is to view it as an argument for constitution-relations between mental and physical events. I return to the view I introduced in part 1, and conclude that the token-token identity-theory should probably be replaced by this constitution-view if theories of de re beliefs are accepted.

Reference Point Heterogeneity.

Terzi, Ayse, Koedijk, Kees, Noussair, Charles N, Pownall, Rachel 12 September 2016 (has links)
It is well-established that, when confronted with a decision to be taken under risk, individuals use reference payoff levels as important inputs. The purpose of this paper is to study which reference points characterize decisions in a setting in which there are several plausible reference levels of payoff. We report an experiment, in which we investigate which of four potential reference points: (1) a population average payoff level, (2) the announced expected payoff of peers in a similar decision situation, (3) a historical average level of earnings that others have received in the same task, and (4) an announced anticipated individual payoff level, best describes decisions in a decontextualized risky decision making task. We find heterogeneity among individuals in the reference points they employ. The population average payoff level is the modal reference point, followed by experimenter's stated expectation of a participant's individual earnings, followed in turn by the average earnings of other participants in previous sessions of the same experiment. A sizeable share of individuals show multiple reference points simultaneously. The reference point that best fits the choices of the individual is not affected by a shock to her income.

Uplatnění generického maskulina v českém textu / The usage of generic masculines in a Czech text

Smithová, Simona January 2011 (has links)
The goal of this master's thesis, "The usage of generic masculines in Czech text," is to present aspects of Czech generic masculines and the concept of gender-correct communication. First, the theoretical portion of the thesis presents the historic background of the concept of gender and the category of grammatical gender with a view to the theory of reference. The research part probes the relationships between the grammatical gender of an expression denoting person or group of people and its reference. There is also a questionnaire illustrating the attitudes of a group of Czech native speakers towards the necessity of gender correctness.

Reference and Presupposition

Bagwell, Jeffrey N. 01 December 2014 (has links)
The topic of this paper is the logical analysis and translation of definite descriptions (structures of the form ‘the F’), in particular Bertrand Russell’s Theory of Descriptions, as put forth in “On Denoting” (1905). I argue in favor of an opposing theory, a presuppositional analysis of definite descriptions that fits in the tradition of Frege and Strawson, building upon the recent work of Heim and Elbourne. I argue that a definite description has a referential function that is supported by presuppositions of existence and uniqueness located outside of the analyzed sentence. Using a series of example sentences, I show that a presuppositional analysis handles the logic of ordinary language in a manner superior to a Russellian analysis, produces more natural readings of embedded sentences containing definite descriptions, explains why definite descriptions function in a consistent way across different types of sentences, and provides a much better account of the logical commitments of using referential terms. After providing background on Russell’s theory and its criticisms, I review and analyze Elbourne’s examples of sentences embedding definite descriptions in non-doxastic propositional attitudes or the antecedents of conditionals. I then present and analyze my own examples involving embedding within disjunctions and within two kinds of non-statement: questions and commands. I compare the effects of embedding sentences using proper names—another kind of referential term. I then analyze some logical consequences of Russellian analysis, and answer a potential Russellian objection.
