    The effects of counterfactual attacks on social judgments

    Two experiments were conducted to compare the effects of different styles of verbal criticism (factual vs. counterfactual) on the perceptions of target, source, and quality of the attack. Counterfactual attacks resulted in more negative overall judgment of the target and ratings of the target's morality than either factual attacks or no attack. Counterfactual attacks were also rated more positively than factual attacks, and the source of the counterfactual attack was rated as being less biased against the target. Regression analyses confirmed that the observed effect on overall judgment was mediated by the perceived bias of the source. The greater effectiveness of counterfactual attacks was moderated by awareness of prior hostility of the source of the attack toward the target

    Questo articolo studia teoricamente l'effetto Doppler per le onde termiche, trovando un'espressione dello spostamento di frequenza per i due casi di sorgente in movimento e osservatore in movimento. Vengono evidenziate differenze e analogie con l'effetto Doppler per onde elettromagnetiche e acustiche. Le onde d'urto termico vengono introdotte e simulate numericamente. Viene discussa anche un'applicazione per la valutazione e il test non distruttivo dei materialiThis paper theoretically studies the Doppler effect for thermal waves, finding an expression of the frequency shift for the two cases of moving source, and moving observer. Differences and analogies with the Doppler effect for electromagnetic and acoustic waves are highlighted. Thermal shock waves are introduced and simulated numerically. An application for nondestructive evaluation and testing of materials is also discussed
