Kvantitativa perspektiv på L2-tal på olika färdighetsnivåer
2021
The aim of this study is to investigate differences in the amount (the occurrence rate) of second language (L2) traits at different proficiency levels in spoken L2 Finland-Swedish. In the analysis, we focus on L2 features in segments, segment lengths, word stress and sentence stress. Further, we analyze the ability to produce speech and the complexity of production at different proficiency levels: the amount of speech, token length, token structure and speech rate. Through previous research, we know that pronunciation plays an important role for comprehensibility and foreign accent but also for the level of oral proficiency. Although pronunciation and different pronunciation features are us…
Measurement of the top quark charge in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
2013
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb[superscript −1] of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 ± 0.02 (stat.) ± 0.08 (syst.) from the charges of the top quark decay products in single lepton t[¯ over t] candidate events. This excludes models that propose a heavy quark of electric charge −4/3, instead of the Standard Model top quark, with a significance of more than 8σ.
Att bedöma skriftliga färdigheter i svenska med hjälp av en nivåskala: hur skillnader mellan bedömare uppstår
2011
Tutkielman tarkoituksena on selvittää, kuinka neljä kokenutta kielitaidon arvioijaa arvioi suomenkielisen yläasteopiskelijan kirjoittaman ruotsinkielisen kirjoitelman käyttäen apunaan Opetushallituksen kielitaidon tasojen kuvausasteikkoa. Tavoitteena on selvittää, missä määrin arvioijat tukeutuvat taitotasoasteikkoon arvioidessaan kirjoitelmaa, millä asteikkoon kuuluvilla tai kuulumattomilla kriteereillä he useimmin perustelevat valintansa sekä miksi arvioijat arvioivat kirjoitelman eri tavoin. Analysoitavaksi kirjoitelmaksi valittiin sellainen, jolle arvioijat määräsivät eri tasoja: kaksi päätyi A2.1:een, yksi A1.3:een ja yksi A2.2:een. Tutkimusmetodina käytettiin puolistrukturoitua teemah…

Playful approaches to news engagement
2020
From crossword puzzles and quizzes to more complex gamification strategies and serious newsgames, legacy media has long explored ways to deploy playful approaches to deliver their content and engage with the audience. We examine how news and games fit together when news organizations, game creators and news audiences welcome gameful forms of communication and participation. Moreover, we reflect on the theoretical and empirical significance of merging news with games as a way to reformulate normative assumptions, production practices and consumption patterns. As a result, the boundaries between journalism and game’s logics start to erode, and they begin to find new ways of converging.
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Value Co-creation for Smart Villages: The Institutionalization of Regional Service Ecosystems
2020
Building a versatile portfolio of public and private digital-enabled services is vital in rural and sparsely populated regions, where traditional market mechanisms alone cannot guarantee the availability of essential services. However, contemporary services tend to build on prevalent institutions, often governed by decisions based on market mechanisms, such as economies of scale – service-by-service and village-by-village. A shift is suggested towards networks of smart villages co-creating value as regional service ecosystems. We draw from institutional theory and employ the Service-dominant logic (SDL) framework in investigating value co-creation in rural villages in Sweden. Analyzing 53 l…
Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?
2022
Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …
Beyond “liberals” and “conservatives”: Complexity in ideology, moral intuitions, and worldview among Swedish voters
2020
This research investigated the congruence between the ideologies of political parties and the ideological preferences (N = 1515), moral intuitions (N = 1048), and political values and worldviews (N = 1345) of diverse samples of Swedish adults who voted or intended to vote for the parties. Logistic regression analyses yielded support for a series of hypotheses about variations in ideology beyond the left-right division. With respect to social ideology, resistance to change and binding moral intuitions predicted stronger preference for a social democratic (vs. progressive) party on the left and weaker preference for a social liberal (vs. social conservative or liberal-conservative) party on t…
