Motivation can be a decisive factor in students’ learning of a foreign language. At the same time, motivation is complex, dynamic, and context sensitive (Papi & Hiver, 2020). Language teachers encounter a wide spectrum of motivational profiles among their students and need to understand the motivation process to find strategies to address students' varying levels of motivation at a given time.
BACKGROUND: Patients undergoing hepato-pancreato-biliary surgery are typically preoperatively assessed using the American Society of Anesthesiologists (ASA) classification, which is also used for case-mix adjustment when comparing centre outcomes. Studies determining the inter-rater variability of the ASA classification within hepato-pancreato-biliary surgery are currently lacking.METHODS: An inte
Let μ be a positive measure supported on a planar domain Ω. We consider the behavior of the balayage measure ν:=Bal(μ,∂Ω) near a point z0∈∂Ω at which Ω has an outward-pointing cusp. Assuming that the order and coefficient of tangency of the cusp are d>0 and a>0, respectively, and that dμ(z)≍|z-z0|2b-2d2z as z→z0 for some b>0 (here d2z is the Lebesgue measure on C), we obtain the leading order term
Background: 25-hydroxyvitamin D3 (25(OH)D3) affects immune function, bone health, and reproduction. The precursor of 25(OH)D3, vitamin D3, is synthesized upon ultraviolet (UV) radiation exposure, the levels of which vary. Methods: In a one-year observational study, we used multiple statistical approaches to examine 25(OH)D3 metabolism and UV exposure in 217 healthy men (aged 30–50 years) not using
PurposeTürkiye ranks among the highest in antibiotic consumption within OECD countries and faces growing challenges from multidrug-resistant uropathogens. Nationwide, resistance-guided treatment data remain scarce. The main objective of this work is to provide a comprehensive nationwide data on antibiotic resistance patterns among uropathogens to guide treatment options in urinary tract infections
BACKGROUND: Reduced lung function has been associated with increased rates of myocardial infarction. Whether the occurrence and prognostic significance of ventricular arrhythmia is related to lung function is largely unknown. METHODS AND RESULTS: We performed a population-based study of 68-year-old men without a history of stroke or myocardial infarction; 402 men participated. Mortality and corona
BACKGROUND AND PURPOSE: Differences in risk factor profiles between lacunar and other ischemic stroke subtypes may provide evidence for a distinct lacunar arteriopathy, but existing studies have limitations. We overcame these by pooling individual data on 2875 patients with first-ever ischemic stroke from 5 collaborating prospective stroke registers that used similar, unbiased methods to define ri
We consider a Casimir apparatus consisting of two perfectly conducting parallel plates, subject to the weak gravitational field of the Earth. The aim of this paper is the calculation of the energy-momentum tensor of this system for a free, real massless scalar field satisfying Neumann boundary conditions on the plates. The small gravity acceleration (considered here as not varying between the two
Popular Abstract in Swedish Variabilitet i ett läkemedels farmakokinetiska (hur ett läkemedel omsätts i kroppen) och farmakodynamiska (vilken effekt ett läkemedel har) egenskaper kan resultera i att olika individer som erhållit samma dos av ett läkemedel får olika effekter av läkemedel. Biverkningar eller utebliven effekt kan innebära allvarliga konsekvenser för den enskilda individen. VariabiliteVariability in pharmacokinetic and pharmacodynamic parameters between individuals can be due to intrinsic and extrinsic factors. In this thesis three different areas regarding sources of variability have been investigated. 1. Formulation properties as an extrinsic source of variability. Lipophilic substances often have poor oral bioavailability and high inter- and intraindividual variability. High
Two proteoglycans differing in size and composition were isolated from human follicular fluid. The larger one of high density had a molecular mass of 3.0x10(6) Da, as determined by laser light-scattering, and was substituted with 15-20 chondroitin sulphate (CS) chains (Mr 60000-65000). Half of the CS disaccharides were 6-sulphated, whereas the remaining ones were non-sulphated. Digestion of the CS
This paper takes the treatment of antonymy in Collins COBUILD Advanced Learner's English Dictionary (2003) as the point of departure for a discussion about the principles of antonym inclusion in dictionaries and corpus methodologies in lexicology. CCALED includes canonical antonyms such as good/ bad and dead/alive, as well as more contextually restricted pairings such as hot/ mild and flat/fizzy.
In trying to understand any aspect surrounding the success and failure of information systems (IS) practice, concepts of organizational analysis become increasingly important. Many issues arise and must be dealt with when an information system is to be developed and implemented. In order to avoid information system failures, information system analysts should adopt an approach that exploits the in
Popular Abstract in Swedish I gruppen huvudhalscancer ingår tumörer i övre luftvägar och svalg. Riskfaktorer för huvudhalscancer är rökning och alkoholöverkonsumtion. Under de senaste 20-30 åren har det skett en påtaglig ökning av insjuknandet, 4-5% per år, i det som kallas orofaryngeal cancer. Orofaryngeal cancer utgår från mellansvalget; mandlar, tungbas och mjuka gommen. Ökningen sammanfaller mThe treatment for head and neck squamous cell carcinoma (HNSCC) is surgery or (chemo)radiotherapy +/- surgery. Side effects related to therapy are long lasting and adversely affects quality of life. The incidence of oropharyngeal cancer is increasing and patients commonly present an advanced tumour stage with neck metastases at the time of diagnosis. The treatment protocol previously comprised rad
Background: Frontotemporal dementia (FTD) is recognised as a clinically and morphologically heterogeneous group of interrelated neurodegenerative conditions. One of the subtypes within this disease spectrum is the behavioural variant FTD (bvFTD). This is known to be a varied disorder with a mixture of tau-positive and tau-negative underlying pathologies. The other subtypes include semantic dementi
Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed
LARS2 has been previously identified as a potential type 2 diabetes susceptibility gene through the low-frequency H324Q (rs71645922) variant (minor allele frequency [MAF] 3.0%). However, this association did not achieve genome-wide levels of significance. The aim of this study was to establish the true contribution of this variant and common variants in LARS2 (MAF > 5%) to type 2 diabetes risk. We
Challengers, as opposed to defenders,of the status quo ascribe more negative motives for the attitudes of their opponentsand more positive motives to their allies. This may be associated with a heightened social cost involved in challenging the generally considered good and true. Most social issues are associated with ideology, and conservatives display more prejudices than liberals. Hence, it is
Purpose: The purpose of this work was to evaluate the visibility of simulated lesions in 2D digital mammography (DM) and breast tomosynthesis (BT) images of patients. Methods: Images of the same women were acquired on both a DM system (Mammomat Novation, Siemens Healthcare, Erlangen, Germany) and a BT prototype system adapted from the same type of DM system. Using the geometrical properties of the
Within the framework of the European Land Arctic Physical Processes project and as part of the Danish Research Council's Polar Program, a study on trace gas exchange in a high-arctic ecosystem was conducted in NE Greenland, May-August 1997. On the basis of carbon dioxide flux measurements from three dominant surface types, this paper reports on the upscaling of such measurements from canopy to lan
In the last years, many vehicle manufacturers have introduced advancedriver support in some of their automobiles. One of those new featuresis Adaptive Cruise Control (ACC), which extends the conventionalcruise control system to control of relative speed and distance toother vehicles. In order to design an ACC controller it is suitable tohave a model on drivers' behavior. Our approach to find dynam
