The overall ambition of this thesis is to investigate the approaches taken to environmental and sustainability education in outdoor education and ecocriticism in a Swedish and in an international context, to investigate environmental meaning making and to conduce to the development of analytical methods for empirical investigations of environmental meaning making. Four objectives are formulated.   The first objective of the thesis is to analyse constitutive discursive rules and traits regarding environmental and sustainability education and environmental meaning making in outdoor education in a Swedish context and in ecocriticism. This is achieved through discourse analyses of central textbooks in outdoor education and of research and textbooks in ecocriticism. The second objective is to investigate how different situated circumstances such as, text, place, mobility, social situations and previous experiences interplay in environmental meaning making. This is achieved through analyses of classroom communication, through analysis of nature writing and through an analysis of painted landscapes. The third objective is to compare and critically discuss the constitutive discursive rules and traits within the two investigated educational practices ­– out door education and ecocriticism ­– in the light of the results from the investigations of environmental meaning making carried out. The fourth objective is to develop analytical methods based on John Dewey and Louise Rosenblatt’s theories of transaction and meaning making for conducting empirical investigations of environmental meaning making in which different interplaying situational circumstances are taken into account. The results of the thesis show that taking a transactional starting point to investigate environmental meaning making adds further understanding of the situational circumstances influencing environmental meaning making in specific situations which sheds new light to the identified approaches to environmental and sustainability education in outdoor education and ecocriticism. These results suggest that a transactional approach to environmental and sustainability education can help to clarify taken for granted assumptions regarding the nature of situational circumstances such as text, place and mobility in environmental meaning making.

The Bleek and Lloyd Collection contains notebooks that document the tradition, language and culture of the Bushman people who lived in South Africa in the late 19th century. Transcriptions of these notebooks would allow for the provision of services such as text-based search and text-to-speech. However, these notebooks are currently only available in the form of digital scans and the manual creation of transcriptions is a costly and time-consuming process. Thus, automatic methods could serve as an alternative approach to creating transcriptions of the text in the notebooks. In order to evaluate the use of automatic methods, a corpus of Bushman texts and their associated transcriptions was created. The creation of this corpus involved: the development of a custom method for encoding the Bushman script, which contains complex diacritics; the creation of a tool for creating and transcribing the texts in the notebooks; and the running of a series of workshops in which the tool was used to create the corpus. The corpus was used to evaluate the use of various techniques for automatically transcribing the texts in the corpus in order to determine which approaches were best suited to the complex Bushman script. These techniques included the use of Support Vector Machines, Artificial Neural Networks and Hidden Markov Models as machine learning algorithms, which were coupled with different descriptive features. The effect of the texts used for training the machine learning algorithms was also investigated as well as the use of a statistical language model. It was found that, for Bushman word recognition, the use of a Support Vector Machine with Histograms of Oriented Gradient features resulted in the best performance and, for Bushman text line recognition, Marti & Bunke features resulted in the best performance when used with Hidden Markov Models. The automatic transcription of the Bushman texts proved to be difficult and the performance of the different recognition systems was largely affected by the complexities of the Bushman script. It was also found that, besides having an influence on determining which techniques may be the most appropriate for automatic handwriting recognition, the texts used in a automatic handwriting recognition system also play a large role in determining whether or not automatic recognition should be attempted at all.

Syftet med studien har varit att introducera den kognitiva receptionsteorin om textvärldar (Text World Theory) samt undersöka utifrån vilka textvärldar barnen på en förskola i Mellansverige interagerar med upplästa texter. Studien har genomförts på avancerad nivå inom Högskolan Dalarnas lärarprogram där huvudområdet varit pedagogiskt arbete. Detta är en kvalitativ studie i vilken två observationer samt två samtal med barngrupp med åldersintervallen tre till sex år har dokumenterats och därefter analyserats i relation till ovan nämnda teori. Av analyser framkommer att öppna frågor i större utsträckning leder till ett byggande av föreställningsvärldar och även en mer avancerad dialog med den diskurs författaren utgår från, än då givna ingångar är utgångspunkten. Studien visar även på att barnen redan tidigt har en avancerad förmåga till textrörlighet samt att de är multimodala i sitt tolkande av texter beroende på vilka textvärldar de relaterar till.

As the popularity of digitally based communication devices increases, so does the propensity for individuals to find clever ways to convey messages in a shorter amount of space and time. Often, individuals use word or phrase shortening techniques known collectively as text-speak. A majority of investigations into the topic of text-speak have only focused on the potential impact text-speak may have on literacy or scholastic achievement (Crystal, 2008; Pinker 1994; Thurlow, 2003). However, there is a void in empirical investigation into how individuals create text-speak and more importantly how they process it (Farrell & Lyddy, 2012). The primary aim of this dissertation is to systematically investigate text-speak using various methodological techniques to gain a better understanding of how people create text-speak and explore how it elicits meaningful comprehension. An additional aim of this dissertation is to determine whether processing text-speak comes at a cognitive cost.

The following study used politeness theory to explore the impact of simultaneously engaging in a face to face conversation and a text message conversation. Specifically the study used Brown and Levinson’s (1978, 1987) five original politeness strategies to see whether strategy choice (in the face to face conversation) impacts the face threat present in engaging in multiple conversations. Multivariate analysis of covariance was used to understand the impact different politeness strategies had on the following variables: conversational appropriateness, relational/social appropriateness, immediacy, attentiveness, and politeness. Findings show that when a face to face partner ignores (no verbal/nonverbal politeness) a text message interruption the partner is seen as more relational/socially appropriate, immediate, attentive, and polite. Findings also indicate that aside from ignoring the text message, politeness messages that acknowledge the text message interruption and offer a relevant verbal message are viewed as more relationally/socially appropriate, immediate, attentive, and polite than those that indirectly deal with the text interruption. This study partially supports the popular belief that texting in the presence of others violates face to face conversational expectations and is perceived as “rude.” However, future studies need to look at the role and influence mediated conversational expectations play in overall conversational expectations.

This project sought to find a rigorous and manageable method for measuring the difficulty of texts in te reo Māori written for children, beyond junior reading material in Māori-medium educational settings. The project examined a range of readability measures based on semantic and/or syntactic features of text, following the work of Warwick Elley (1969) and Richard Benton et al. (1995). Features such as the difficulty of content words, average sentence length, standardised type:token ratios and the use of function words were used in different combinations to create seven methods to measure text difficulty. Teachers’ and students’ ratings of text difficulty, and students’ scores on reading comprehension tasks related to the texts were used as criteria to examine the validity of the readability methods. The findings revealed that indices of either vocabulary load or lexical density when used in combination with the number of function types in the text, produce statistical significance with the criterion measures. Further research is needed to confirm their validity for use in Māori –medium classroom settings. The Māori word lists developed for this project as the basis of the readability approaches have the potential for more widespread analyses of language proficiency measures for students in Māori-medium settings.

The amount of information available on the web is growing constantly. As a result, theproblem of retrieving any desired information is getting more difficult by the day. Toalleviate this problem, several techniques are currently being used, both for locatingpages of interest and for extracting meaningful information from the retrieved pages.Information extraction (IE) is one such technology that is used for summarizingunrestricted natural language text into a structured set of facts. IE is already being appliedwithin several domains such as news transcripts, insurance information, and weatherreports. Various approaches to IE have been taken and a number of significant resultshave been reported.In this thesis, we describe the application of IE techniques to the domain of universityweb pages. This domain is broader than previously evaluated domains and has a varietyof idiosyncratic problems to address. We present an analysis of the domain of universityweb pages and the consequences of having them input to IE systems. We then presentUniversityIE, a system that can search a web site, extract relevant pages, and processthem for information such as admission requirements or general information. TheUniversityIE system, developed as part of this research, contributes three IE methods anda web-crawling heuristic that worked relatively well and predictably over a test set ofuniversity web sites.We designed UniversityIE as a generic framework for plugging in and executing IEmethods over pages acquired from the web. We also integrated in the system a genericweb crawler (built at the University of Kentucky) and ported to Java and integrated anexternal word lexicon (WordNet) and a syntax parser (Link Grammar Parser).
