Foreign language enjoyment and anxiety: The effect of teacher and learner variables

Positive psychology has boosted interest in the positive as well as the negative emotions that Foreign Language learners experience. The present study examines whether – and to what extent – foreign language enjoyment (FLE) and foreign language (FL) classroom anxiety (FLCA) are linked to a range of learner internal variables and teacher/classroom-specific variables within one specific educational context. Participants were 189 British high school students learning various FLs. Higher levels of FLE were linked to higher scores on attitudes towards the FL, the FL teacher, FL use in class, proportion of time spent on speaking, relative standing and stage of development. Lower levels FLCA were linked to higher scores on attitudes towards the FL, relative standing and stage of development. FLCA thus seems less related to teacher and teacher practices than FLE. The pedagogical implication is that teachers should strive to boost FLE rather than worry too much about students’ FLCA

Swearing, Euphemisms, and Linguistic Relativity

Participants read aloud swear words, euphemisms of the swear words, and neutral stimuli while their autonomic activity was measured by electrodermal activity. The key finding was that autonomic responses to swear words were larger than to euphemisms and neutral stimuli. It is argued that the heightened response to swear words reflects a form of verbal conditioning in which the phonological form of the word is directly associated with an affective response. Euphemisms are effective because they replace the trigger (the offending word form) by another word form that expresses a similar idea. That is, word forms exert some control on affect and cognition in turn. We relate these findings to the linguistic relativity hypothesis, and suggest a simple mechanistic account of how language may influence thinking in this context

Direct measurement of thermal conductivity in solid iron at planetary core conditions

The conduction of heat through minerals and melts at extreme pressures and temperatures is of central importance to the evolution and dynamics of planets. In the cooling Earth’s core, the thermal conductivity of iron alloys defines the adiabatic heat flux and therefore the thermal and compositional energy available to support the production of Earth’s magnetic field via dynamo action1, 2, 3. Attempts to describe thermal transport in Earth’s core have been problematic, with predictions of high thermal conductivity4, 5, 6, 7 at odds with traditional geophysical models and direct evidence for a primordial magnetic field in the rock record8, 9, 10. Measurements of core heat transport are needed to resolve this difference. Here we present direct measurements of the thermal conductivity of solid iron at pressure and temperature conditions relevant to the cores of Mercury-sized to Earth-sized planets, using a dynamically laser-heated diamond-anvil cell11, 12. Our measurements place the thermal conductivity of Earth’s core near the low end of previous estimates, at 18–44 watts per metre per kelvin. The result is in agreement with palaeomagnetic measurements10 indicating that Earth’s geodynamo has persisted since the beginning of Earth’s history, and allows for a solid inner core as old as the dynamo

Differences in emotional reactions of Greek, Hungarian, and British users of English when watching television in English

We investigated differences in self‐reported Emotional Reactions (ER) of first (L1) and foreign (LX) language users of English when watching television in English and identified the predictors. Participants were 271 British citizens, 282 Greek, and 271 Hungarians living in their home country. English LX users had significantly lower values for ER compared to L1 users. Frequency of watching television in English and Trait Emotional Intelligence were the strongest predictors of ER among LX users. No significant predictors emerged for L1 users. Significant differences emerged between the Greeks and Hungarians despite having similar levels of proficiency. This suggests that the implicit assumption in previous research that any group of LX users with the same L1 and LX represent all LX users in the world is incorrect

Variable region heavy chain glycosylation determines the anticoagulant activity of a factor VIII antibody.

BACKGROUND: N-glycosylation occurs in the variable region of about 10% of antibodies but the role of carbohydrate at this location is still poorly understood. OBJECTIVES: We investigated the function of N-glycosylation in the variable region of the heavy chain of a human monoclonal antibody, mAb-LE2E9, that partially inhibits factor VIII (FVIII) activity during coagulation. METHODS AND RESULTS: Enzymatic deglycosylation indicated that the oligosaccharides do not determine the affinity of the antibody but enhance its FVIII neutralizing activity. A mutant antibody lacking the N-glycosylation site in the variable region of the heavy chain inhibited FVIII activity by up to 40%, while inhibition by the native antibody was 80%. To evaluate the physiological effect of such a FVIII inhibition, we investigated the ability of the mutant antibody devoid of N-glycosylation in the variable region to prevent thrombosis in mice with a strong prothombotic phenotype resulting from a type II deficiency mutation in the heparin binding site of antithrombin. Despite its moderate inhibition of FVIII activity, the mutant antibody significantly prevented thrombosis in treated animals. We also carried out glycan analysis of native and mutant antibodies. CONCLUSIONS: Modification of glycosylation in the variable region of antibodies contributes to the diversity of FVIII type II inhibition possibly by steric hindrance of the active site of FVIII by glycans, and may provide a novel strategy to modulate the functional activity of therapeutic antibodies
