Can empathy lead to emotional exhaustion in teachers? The mediating role of emotional labor

Objectives: The present study was designed to examine the links between empathy, emotional labor (both surface and deep acting), and emotional exhaustion as well as determine if emotional labor mediates the relationship between empathy and emotional exhaustion in teachers. It was assumed that emotional labor can take two opposite directions (positive mood induction and negative mood induction). Thus, the additional aim of the study was to analyze the mediating role of mood regulation strategies in the relationship between empathy and emotional exhaustion. Materials and Methods: A sample of 168 teachers from Łódź and its surroundings completed a set of questionnaires: Emotional Labor Scale; Mood Regulation Scales, Maslach Burnout Inventory, and Empathic Sensitivity Scale. Results: The results provided mixed support for the hypotheses indicating that both types of emotional labor, negative mood induction and emotional exhaustion were positively intercorrelated. Moreover, deep acting was a significant mediator in the relationship between empathy and emotional exhaustion. The analyzed link was also mediated by negative mood induction, whereas positive mood induction did not emerge as a significant mediator. Conclusions: The study provided insight into the role of empathy and emotional labor in the development of teacher burnout. It also confirmed that deep acting and negative mood induction mediate the relationship between empathy and emotional exhaustion in teachers

New implications in the use of imposex as a suitable tool for Tributyltin contamination: experimental induction in Hexaplex trunculus (Gastropoda, Muricidae) with different stressors

Imposex, i.e. the development of additional male sex organs (penis and/or vas deferens), in females of gonochorist marine and freshwater gastropods, is known to be caused by tributyltin (TBT), and it has been widely used as a biomonitoring tool in environmental surveys for TBT pollution assessment. In this study, we experimentally tested the potential to induce imposex by another endocrine disruptor (polychlorinated biphenyls [PCBs] mixture—Aroclor 1260). Adults of Hexaplex trunculus with low imposex level, coming from an Italian Marine Protected Area, were injected separately with different doses of tributyltin chloride (TBTCl) and Aroclor 1260. The compounds were dissolved in ethanol and the organisms were narcotised by immersion in MgCl2 solution before injection. Before and after the experiment, butyltin compounds (BuTs) and PCB tissue concentrations were determined. A significant increase in imposex with respect to non-treated organisms was observed in all treatments, including artefact controls. No clear correlation was observed between BuTs and PCB tissue concentrations and indices of imposex incidence. Based on these results, no assumption can be formulated about PCB effect on imposex development. Nevertheless, they suggest that the imposex level increase, at least in H. trunculus, in laboratory conditions might not be caused by TBT only, but it would rather be a non-specific response to different stress stimuli
