Effects of age and stimulus material on character introductions of Swedish-speaking four- to six-year-olds

Tidskriftsartikel (refereegranskat)abstract
- This study investigates effects of age on character introductions in the oral narratives of seventy-two monolingual Swedish-speaking four- to six-year-olds, comparing results from the Multilingual Assessment Instrument for Narratives (MAIN; Gagarina et al., 2012, 2015), and the Edmonton Narrative Norms Instrument (ENNI; Schneider et al., 2005). The proportion of appropriate referring expressions for introducing story characters clearly increases from age four to six. However, the children's performance is strongly stimulus-dependent. All age groups perform better on MAIN than on ENNI. One should thus be careful when drawing conclusions about the age at which children are able to use referring expressions appropriately.

Pause and utterance duration in child-directed speech in relation to child vocabulary size
- 2015

Tidskriftsartikel (refereegranskat)abstract
- This study compares parental pause and utterance duration in conversations with Swedish speaking children at age 1;6 who have either a large, typical, or small expressive vocabulary, as measured by the Swedish version of the McArthur-Bates CDI. The adjustments that parents do when they speak to children are similar across all three vocabulary groups; they use longer utterances than when speaking to adults, and respond faster to children than they do to other adults. However, overall pause duration varies with the vocabulary size of the children, and as a result durational aspects of the language environment to which the children are exposed differ between groups. Parents of children in the large vocabulary size group respond faster to child utterances than do parents of children in the typical vocabulary size group, who in turn respond faster to child utterances than do parents of children in the small vocabulary size group.

Subjective ratings of age-of-acquisition : exploring issues of validity and rater reliability
- 2019
-
Ingår i: Journal of Child Language. - 0305-0009 .- 1469-7602. ; 46:2, s. 199-213

Tidskriftsartikel (refereegranskat)abstract
- This study aimed to investigate concerns of validity and reliability in subjective ratings of age-of-acquisition (AoA), through exploring characteristics of the individual rater. An additional aim was to validate the obtained AoA ratings against two corpora – one of child speech and one of adult speech – specifically exploring whether words over-represented in the child-speech corpus are rated with lower AoA than words characteristic of the adult-speech corpus. The results show that less than one-third of participating informants’ ratings are valid and reliable. However, individuals with high familiarity with preschool-aged children provide more valid and reliable ratings, compared to individuals who do not work with or have children of their own. The results further show a significant, age-adjacent difference in rated AoA for words from the two different corpora, thus strengthening their validity. The study provides AoA data, of high specificity, for 100 child-specific and 100 adult-specific Swedish words.

Integrated Method for Purification and Single-Particle Characterization of Lentiviral Vector Systems by Size Exclusion Chromatography and Tunable Resistive Pulse Sensing
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Elements derived from lentiviral particles such as viral vectors or virus-like particles are commonly used for biotechnological and biomedical applications, for example in mammalian protein expression, gene delivery or therapy, and vaccine development. Preparations of high purity are necessary in most cases, especially for clinical applications. For purification, a wide range of methods are available, from density gradient centrifugation to affinity chromatography. In this study we have employed size exclusion columns specifically designed for the easy purification of extracellular vesicles including exosomes. In addition to viral marker protein and total protein analysis, a well-established single-particle characterization technology, termed tunable resistive pulse sensing, was employed to analyze fractions of highest particle load and purity and characterize the preparations by size and surface charge/electrophoretic mobility. With this study, we propose an integrated platform combining size exclusion chromatography and tunable resistive pulse sensing for monitoring production and purification of viral particles.

Forskningsöversikt (refereegranskat)abstract
- Purpose – This paper aims to review research on the topic of knowledge leakage to establish the current body of knowledge and, on this basis, to suggest some promising avenues for future research.Design/methodology/approach – The study consists of a systematic review of 57 refereed empirical articles on knowledge leakage.Findings – The findings contribute to a more holistic view of the topic and complement the study of knowledge management. Additionally, a conceptual framework is proposed that aims at guiding and informing future research activities.Research limitations/implications – This study may not have enabled a complete coverage of all empirical articles in the field of knowledge leakage. Yet, based on the chosen research methodology, it seems reasonable to assume that the review process covered a large share of studies available.Originality/value – To the best of the authors’ knowledge, no systematic literature review on knowledge leakage has previously been published in academic journals.
