Keeping in time : The design of qualitative longitudinal research in SLA

Language development is a long-term process. Individual-level longitudinal case studies have been foundational to SLA. However, methodologies that can support person-focused and process-oriented research lack consolidation. Qualitative longitudinal (QL) research (Neale, 2021a, 2021b) is a methodology that facilitates exploration of the influences of time over time. It provides a temporal architect

Lagspråk och skriftlighet : Det formella skriftspråkets konstruktionssyntax som grund för lagspråksförenkling och EU-översättning

Den här boken handlar om de lexikogrammatiska förutsättningarnaför välfungerande och rimligt lättillgängliga inhemska lagtexter ochöversatta EU-rättsakter och -domar. Bokens huvudtes är attspråkformen i bägge fallen måste grundas på skriftlighet, dvs. på ettkvalificerat bruk av hela det formella skriftspråketskonstruktionsregister och med strikt tillämpning av dess generellanormsystem.

Landscape and management influences on smallholder agroforestry yields show shifts during a climate shock

Sustaining yields for smallholder perennial agriculture under a rapidly changing climate regime may require consideration of landscape features and on-farm management decisions in tandem. Optimising landscape and management may not be possible for maximising yields in any one year but maintaining heterogeneous landscapes could be an important climate adaptation strategy. In this study, we observed

The dispute between Ethiopia and Egypt over the Grand Ethiopian Renaissance Dam

The construction of large hydro infrastructures often causes severe socio-environmental issues. When the facility is projected on transboundary rivers, such as the Nile, these issues may become political and involve a much greater number of actors. The Grand Ethiopian Renaissance Dam (GERD) is provoking significant geopolitical tensions in the Horn of Africa since it involves two of the most dynam

Taking a long view towards quality improvement : an intentional approach to solving wicked problems and improving student experience

Quality enhancement projects in universities frequently rely on short-term, fragmented studies implemented in response to snapshot data linked to student feedback. Such projects may not address the complex interplay across stakeholder groups and do not always acknowledge the unintended consequences of change. This article, focused on systems design, draws on research conducted over seventeen years

Omega-3 fatty acids for inflamed depression - A match/mismatch study

Despite decades of research on the pathophysiology of depression, the development of new therapeutic interventions has been slow, and no biomarkers of treatment response have been clinically implemented. Several lines of evidence suggest that the clinical and biological heterogeneity among patients with major depressive disorder (MDD) has hampered progress in this field. MDD with low-grade inflamm

Beijing's interest in the African continent is strong. For some time, China has been investing considerable capital to increase its influence in many sub-Saharan nations, often rich in raw materials and resources considered essential for Chinese industrial growth. In this respect, a very interesting case concerns Tanzania, a significant African state facing the Indian Ocean that has recently estab

Campylobacter infections with and without bacteraemia- a comparative retrospective population-based study

BackgroundBacteraemia with species in the genus Campylobacter is rare, and knowledge of the disease course in comparison to Campylobacter enteritis is limited.MethodsThis is a retrospective population-based study. Episodes of Campylobacter bacteraemia, and Campylobacter enteritis with a concurrent negative blood culture, that occurred between 2015 and 2022 in southern Sweden were identified throug

Structured Light for Ultrafast Videography

Monitoring natural events at ultrafast timescales is a prerequisite for our continued understanding of physical, chemical and biological processes. Due to exponential advancements in knowledge and optical technology, the field of ultrafast videography has seen a sudden uptick in activity beginning in the mid-2010s. Today, the field has matured past its infancy and is slowly becoming a standard too

Pre-service teachers’ explanations of division by zero and denseness of the number line.

Students’ beliefs about division by zero and numbers on the number line werestudied through explanations of the concepts in questionnaires and interviewsduring their teacher education to become primary school teachers in the years4–6. The concepts were chosen for students’ proven cognitive challenges incoping with them, with the aim to add to the existing knowledge in terms ofspecific and general

Mathematics and physics at upper secondary school: an analysis of two lectures

A physics lecture and a mathematics lecture, by the same teacher and partly thesame students, were studied at upper secondary school. Both lectures coveredordinary differential equations. The main aim of the present paper was to investigate the teacher’s different and similar ways to handle related mathematicalcontent in the two school subjects. The findings show a structural use of mathematics wi

Is there Really an Effect of Time Delays on Perceived Fluency and Social attributes between Humans and Social Robots? A Pilot Study

Humans are expert percievers of behavioural properties, including the timing of movements. Even short hesitancies and delays can be salient depending on the context. This article presents results from a pilot study on time delays in a human-robot interaction setting using the Wizard of Oz paradigm. Participants (n=17) played Tic-Tac-Toe with the humanoid robot Epi. They were randomized into one of

Chronic kidney disease and its association with cerebral small vessel disease in the general older hypertensive population

BackgroundCerebral small vessel disease can be identified using magnetic resonance imaging, and includes white matter hyperintensities, lacunar infarcts, cerebral microbleeds, and brain atrophy. Cerebral small vessel disease and chronic kidney disease share many risk factors, including hypertension. This study aims to explore an association between chronic kidney disease and cerebral small vessel

Data-driven Train Delay Prediction

In Sweden, extensive use and the inherent heterogeneity of train traffic have significantly increased the sensitivity of the train system so that the delay of one train can easily propagate to others. Repeated experiences with train delays can lead passengers to perceive that railway transportation is unreliable. Despite being considered a green mode of transport, this environmental benefit truly

Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

Vid utformning och dimensionering av såväl anläggningskonstruktioner som enskilda byggnadsdelar måste vanligtvis ett flertal olika belastningssituationer analyseras. Utöver statiska lastfall kan det vara nödvändigt att beakta dynamiska laster, såsom explosions- eller stötlast. För att påvisa tillräcklig bärförmåga används i allmänhet datorbaserade beräkningsmodeller, ofta framtagna med finita elemA structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. To this end, the response can be estimated using computational models representing an idealized structure, often formulated using the finite element

Population genomic analyses reveal that salinity and geographic isolation drive diversification in a free-living protist

Protists make up the vast diversity of eukaryotic life and play a critical role in biogeochemical cycling and in food webs. Because of their small size, cryptic life cycles, and large population sizes, our understanding of speciation in these organisms is very limited. We performed population genomic analyses on 153 strains isolated from eight populations of the recently radiated dinoflagellate ge
