- This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability-for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples.

Tidskriftsartikel (refereegranskat)abstract
- A field campaign was conducted to measure and analyze 13 polycyclic aromatic hydrocarbons (PAHs) in six major zones in the city of Shanghai, P.R. China from August 2006 to April 2007. Ambient air samples were collected seasonally using passive air samplers, and gas chromatography-mass spectroscopy was used in this field campaign. The results showed that there was a sequence of 13 PAHs at Phen > FA > Pyr > Chr > Fl > An > BaA > BbFA > BghiP > IcdP > BkFA > BaP > DahA and the sum of these PAHs is 36.01 ± 10.85 ng/m3 in gas phase. FL, Phen, FA, Pyr, and Chr were the dominant PAHs in gas phase in the city. They contributed 90% of total PAHs in the gas phase. Proportion of measured PAHs with three, four, five, and six rings to total PAHs was 53%, 42%, 3%, and 2%, respectively. The highest concentration of ∑PAHs (the sum of 13 PAHs) occurred in the wintertime and the lowest was in the summer. This investigation suggested that traffic, wood combustion, and metal scrap burn emissions were dominant sources of the concentrations of PAHs in six city zones compared with coal burning and industry emissions. Further, the traffic emission sources of PAHs in the city were attributed mostly to gasoline-powered vehicles compared with diesel-powered vehicles. It was revealed that the seasonal changes in PAHs in the city depended on different source types. Metal scrap burn was found to be the major source of PAHs during the autumn, while the PAH levels in the atmosphere for winter and spring seasons were mainly influenced by wood and biomass combustion. Comparisons of PAHs among different city zones and with several other cities worldwide were also made and discussed.

Predatory publishers’ spam emails as a symptom of the multiple vulnerabilities in academia
- 2023. - 1st
-
Ingår i: Predatory Practices in Scholarly Publishing and Knowledge Sharing. - London : Routledge. - 9781003170723 ; , s. 19-38
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter analyzes a large corpus of spam emails spanning a six-year period (2016–2021) with the following two main goals: firstly, to uncover the linguistic features of these texts, and secondly, to connect the linguistic and textual analysis with the discursive and cultural contexts in which these spam emails are embedded. The corpus-based analysis performed in the chapter shows the different topics that predatory publishers’ spam emails focus on, and the ways in which these topics have changed and evolved over time. The main argument in the discussion is that predatory publishers are acutely aware of some of the key features structuring present-day academic publishing. In conclusion, in order to enable more effective ways of tackling the challenges posed by predatory publishing, both analyses and discourses about them should be shifting from a focus on the danger and risks they represent to the actual structuring features that make the existence of predatory publishing possible and viable.

Let's say : Phraseological patterns of SAY in academic ELF communication
- 2021

Ingår i: Journal of English for Academic Purposes. - : Elsevier. - 1475-1585 .- 1878-1497. ; 54

Tidskriftsartikel (refereegranskat)abstract
- Formulaic sequences (e.g., on the other hand, for example, as can be seen) are prevalent in academic discourse. Apart from their various functions, research in the field has uncovered a range of contextual and individual factors associated with the use of formulaic sequences, including genre, discipline, and the user's L1 as well as expertise level. However, most previous studies focus on written discourse and employ a frequency-based approach (e.g., lexical bundles, n-grams). The inherent limitations of the approach are of particular relevance to ELF communication, which involves a high degree of flexibility adaptability. The present study aims to explore features of formulaicity in spoken ELF academic discourse. Through a close examination of the phraseological patterns of one verb SAY in a one-million-word corpus of spoken ELF communication in academic settings, the present study is able to overcome some of the limitations of the frequency approach, thereby shedding further light on formulaicity in language use characterising this particular community and its relationship with factors such as event type, discipline, and individual preference.

Emergency Risk Communication : A Structural Topic Modelling Analysis of the UK government’s COVID-19 Press Briefings
- 2022

Tidskriftsartikel (refereegranskat)abstract
- The ongoing coronavirus outbreak has caused a public health emergency of international concern. During public health emergencies, effective risk communication plays an indispensable part in a country’s emergency response. This paper explores the use of Structural Topic Modelling, a machine learning technique that automatically identifies key topics and their content in textual data, in analysing emergency risk communication (ERC) practice at the state level. The data is from the UK government’s COVID-19 press briefings televised between March 2020 and June 2021, totalling approximately 1 million words. The study identifies the prominent topics covered in those briefings as well as their distribution over time, which in turn reflect the UK government’s priorities in handling the public health emergency. Close scrutiny of the use of a selection of key words in context sheds further light on the government’s ERC practice from a linguistic point of view.

Exploring the effects of target-language extramural activities on students’ written production
- 2023
-
Ingår i: Journal of second language writing. - : Elsevier. - 1060-3743 .- 1873-1422. ; 62

Tidskriftsartikel (refereegranskat)abstract
- Frequent engagement in English extramural activities (i.e., activities that take place outside the classroom) has been found to have a positive impact on EFL learners’ vocabulary knowledge and reading comprehension. In the present study, we aim to extend our knowledge of the possible impact of extramural activities into the realm of second-language writing. Specifically, we investigate the relationship among a number of English extramural activities and two aspects of writing development: lexical diversity and noun phrase complexity. The data are drawn from the Swedish Learner English Corpus (SLEC) which includes texts produced by Swedish secondary school students. The corpus also includes information on how many hours per week students (i) engage in conversations in English, (ii) communicate in English while playing computer/video games, (iii) read in English, (iv) spend time on social media with English content, (v) and watch TV shows or movies in English. The results show that reading in English leads to higher frequency of adjectival modification, whereas conversing in English and watching TV programs positively impact lexical diversity. The results of the study have implications for discussions about the role of L2 classroom instruction vis-à-vis learners’ extramural activities.

Tidskriftsartikel (refereegranskat)abstract
- This paper introduces the Swedish Learner English Corpus (slec), which consists of argumentative texts in English that are written by Swedish junior and senior high school students. slec includes rich metadata, enabling empirical studies of various extra-linguistic variables. Most noteworthy is the inclusion of detailed information on students’ extramural English activities (ee), such as reading, watching, conversing, gaming and engaging in social media in English. In addition, a sub-set of texts from slec have been assessed for proficiency using the Common European Framework of Reference for Languages (cefr). This paper provides an overview of the corpus compilation process, the metadata, and the available versions of slec. Researchers, teachers and students can access this resource to investigate various aspects of second language use and development, such as the impact of extramural language activities on linguistic complexity.
