Teachers’ occupational well-being in relation to teacher–student interactions at the lower secondary school level
2023
This study investigated the relation between teachers’ occupational well-being and the quality of teacher–student interactions in lower secondary schools in Finland. Teachers (N = 48) self-rated their occupational well-being in terms of engagement, stress, job demands, and emotional exhaustion. Teacher–student interactions in classrooms were video-recorded and coded with the Classroom Assessment Scoring System. The results of multivariate regression analyses showed that teachers who reported higher work-related stress were observed with a lower quality of emotional support, classroom organization, and instructional support when controlling for background factors. It is proposed that the obs…
Phosphorus limitation enhances parasite impact: feedback effects at the population level
2014
Background Nutrient deficiency affects the growth and population dynamics of consumers. Endoparasites can be seen as consumers that drain carbon (C) or energy from their host while simultaneously competing for limiting resources such as phosphorus (P). Depending on the relative demands of the host and the parasite for the limiting nutrient, intensified resource competition under nutrient limitation can either reduce the parasite’s effect on the host or further reduce the fitness of the nutrient-limited host. So far, knowledge of how nutrient limitation affects parasite performance at the host population level and how this affects the host populations is limited. Results We followed the popu…
Crystal structures of 4-chloro-pyridine-2-carbo-nitrile and 6-chloro-pyridine-2-carbo-nitrile exhibit different inter-molecular π-stacking, C-H⋯Nnitr…

The crystal structures of two chlorocyanopyridines, namely 4-chloropyridine-2-carbonitrile and 6-chloropyridine-2-carbonitrile, exhibit unique intermolecular C—H⋯Nnitrile, C—H⋯Npyridine and offset face-to-face π-stacking interactions.
