Substantial evidence emphasizing the importance of linguistic systems in reading acquisition, as well as emerging literature identifying the contribution of executive function to linguistic-based difficulties, underscores the importance of clarifying the neurocognitive mechanisms affecting reading performance. Research demonstrating the interrelationship between reading and spelling, coupled with neurocognitive theories of spelling, suggests that analysis of children’s spelling attempts may capture more subtle differences in their understanding of how to decode text. This study aimed to determine the utility of applying a spelling error analysis system as a method for differentiating between reading difficulties resulting from executive dysfunction or language deficits in a sample of children at risk for reading failure. The present study examined the relationship between executive function, language, and spelling achievement in a sample of 82 children aged 6-15 years identified as having a reading deficit and/or diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). Hierarchical regression analyses indicated language-based skills, particularly word reading, and age significantly predicted the phonemic equivalency of misspellings. Tasks of executive functioning were not found to significantly contribute to performance on phonological spelling; however, analysis of group differences suggest that ADHD and Reading Deficit groups demonstrated unique cognitive profiles, including distinct performances on executive functioning tasks. Exploratory analyses also revealed that ADHD and Reading Deficit groups differed significantly in phonological spelling performance. Results from the current study provide evidence for the presence of two distinct underlying cognitive processes affecting spelling and, in effect, reading. Current findings have implications for the need to further examine characteristic deficits in language and executive functioning affecting children at risk for reading failure. Findings also provide support for the validity of further investigating the potential to infer differential diagnostic categories using a phonological spelling analysis. The use of an analysis of spelling errors as a diagnostic data source holds promise for a better understanding of reading failure and, ultimately, may contribute to more effective intervention practices. / text

Föreliggande studies syfte är att undersöka hur tre svensklärare som undervisar i årskurs 2 och 3 stöttar elevernas stavningsutveckling. För att samla in studiens data används metoden Design-based Research (Anderson & Shattuck, 2012) där observationer visar hur de deltagande lärarna genomför stavningsundervisning samtidigt som intervjuer används för att se hur studiens deltagare säger sig planera och utvärdera sin stavningsundervisning. Med hjälp av observationer och semistrukturerade intervjuer har relevant data för studiens syfte samlats in. Studiens teoretiska ram grundar sig i det sociokulturella perspektivet med utgångspunkt i begreppet stöttning. Vidare analyseras studiens insamlade data med hjälp av fem stöttningskomponenter: ägarskap, lämplighet, struktur, samarbete och internalisering (Langer & Applebee, 1986). Observationerna visar att studiens deltagare genomför sin stavningsundervisning med en liknande struktur. Däremot framkommer det av intervjuerna att endast en av tre deltagare kontinuerligt undervisar om stavningsregler. Samma deltagare väljer också att rätta alla uppkomna stavfel, medan de andra deltagarna väljer att göra olika beroende på situation. Dessa två deltagare är rädda att för hård stavningsrättning hämmar elevernas skrivlust. Trots att deltagarna har olika syn på effektiv stavningsundervisning och väljer att arbeta på olika sätt kan vi urskilja de fem komponenterna av stöttning hos samtliga deltagare.

Philosophiae Doctor - PhD / Short Message Service (SMS) is one of the most popularly used services for communication between mobile phone users. In recent times it has also been proposed as a means for information access. However, there are several challenges to be overcome in order to process an SMS, especially when it is used as a query in an information retrieval system.SMS users often tend deliberately to use compacted and grammatically incorrect writing that makes the message difficult to process with conventional information retrieval systems. To overcome this, a pre-processing step known as normalization is required. In this thesis an investigation of SMS normalization algorithms is carried out. To this end,studies have been conducted into the design of algorithms for translating and normalizing SMS text. Character-based, unsupervised and rule-based techniques are presented. An investigation was also undertaken into the design and development of a system for information access via SMS. A specific system was designed to access information related to a Frequently Asked Questions (FAQ) database in healthcare, using a case study. This study secures SMS communication, especially for healthcare information systems. The proposed technique is to encipher the messages using the secure shell (SSH) protocol.

This study investigates spelling errors among Swedish students of English. The purpose of this research is to develop a better understanding of the causes of spelling errors and to investigate whether there are any differences between program orientation and gender. The participants are English A students from Swedish high schools in year 1. The data analysed in this study consists of essays written by the participants which have been gathered into the Uppsala Learner English Corpus (ULEC). The results showed that the academic program has a lower error rate when compared to the vocational program and that female students display a lower error frequency than male students. These results reflect the same pattern found by previous studies on achievement between the programs and across gender. However, when comparing all variables, both gender and program, the results demonstrate that academic male students had the lowest error rate of all groups, which could partially be explained by the fact that the academic male students have a higher level of engagement with video- and online games when compared to the other groups. The language processes that the participants found the most challenging were letter omission, letter insertion and letter substitution. These results follow the same pattern highlighted in previous studies on spelling among both native speakers and learners. Finally, the exchange between the vowels <a>, <e> and <i> was found to be a frequent error among the students. Experiencing difficulties with the correct usage of vowels can be explained as a transfer error.

Proper spelling is important for efficient communication between people with different first languages in the 21st century. While Swedish functions as an intranational language within Sweden, it sees little to no use outside of Scandinavia. English fills the role as a second language that all Swedish students must learn, yet more focus appears to be given to grammar rather than spelling. Spelling is important and knowing the kinds of spelling errors Swedish learners of English tend to make can help educators improve the spelling proficiency of their students. The aim of this study is to investigate the spelling errors made by senior high school students in Sweden by analyzing a collection of essays written by students and gathered in the Uppsala Learner English Corpus (ULEC). The results of this study show that spelling proficiency nearly doubled for students in their third year in senior high school compared to their first year, yet the distribution of spelling errors remained the same. Additionally, some particular sounds that appear to be especially problematic for Swedish spellers were identified, such as /ə/, /l/, /s/ and /k/. / Korrekt stavning är viktig för effektiv kommunikation mellan människor med olika modersmål i tjugohundratalet. Medans svenska fungerar som ett språk mellan människor inom Sverige, ser det lite till ingen nytta utanför Skandinavien. Engelska fyller rollen som andraspråk som alla svenska elever måste lära sig, ändå sätts mer fokus på grammatik över stavning. Stavning är viktig och att veta vilka typer av stavfel som svenska elever brukar göra på engelska kan hjälpa lärare förbättra elevernas stavningskunskaper. Syftet med den här studien är att undersöka svenska gymnasielevers felstavningar i Engelska genom att analysera en samlig essäer skrivna av studenter och samlade i Uppsala Learner English Corpus (ULEC). Resultaten från den här studien visar att stavningskunskaperna hos eleverna hade nästan fördubblats när de gick det tredje år på gymnasiet jämfört med när de gick det första, men att fördelningen av stavfel förblev densamma. Dessutom har vissa ljud identifierats som verkar vara särskilt problematiska för svenska elever att stava, såsom /ə/, /l/, /s/ and /k/.
