Int.rnat.onal Journal of Disast.r Risk Science 2024年第3期15卷 332-345页

作者： St.fan R?seler Micha Hilbert.Guido Hert.l Meinald t.t.ielsch Depart.ent.of Psychology University of Münster

Leadership courses in t.e fire services are highly challenging, and t.ey can seriously exhaust.t.ainees and hamper t.eir selfregulat.d learning effort.(for example, set.ing goals, focusing at.ent.on, seeking feedback). We t.eorize t.at.experiences of failure or overload can curt.il t.ainees' available energy resources on subsequent.t.aining days, which, in t.rn, should affect.t.ainees' learning effort.. Given inst.uct.rs' cent.al role in leadership courses, we hypot.esize t.at.support.ve and humble inst.uct.r behaviors decrease experiences of failure and overload and, t.us, increase self-regulat.d learning. Moreover, we argue t.at.support.ve inst.uct.r behavior may amplify t.e posit.ve effect. of high energy resources, while humble behavior may alleviat. t.e negat.ve impact.of low resource levels. We t.st.d preregist.red hypot.eses wit. 118 firefight.rs part.cipat.ng in t.o-week leadership courses at.a German fire academy. t.e part.cipant. complet.d short.web-based quest.onnaires before and aft.r classes each day. Mult.level analyses confirmed t.at.perceived daily support.ve and humble inst.uct.r behavior predict.d t.ainees' report. of daily self-regulat.d learning act.vit.. Not.bly, t.is effect.was independent.from posit.ve effect. of t.ainees' report.d energy resources in t.e morning. Support.ve and humble behavior did not.moderat. t.e eff ect.of energy resources. Our findings suggest.t.at.inst.uct.rs play a crucial role in facilit.t.ng effect.ve learning under challenging t.aining condit.ons. Furt.ermore, we offer implicat.ons for leaders in fire services, who oft.n conduct.t.ainings wit. t.eir subordinat.s.

四月的一天,一场漫长的大雨过后,一只红衣凤头鸟从绿色的树枝下探出头来,看看自己是会淋湿还是会保持干爽。当感觉不到雨水时,它就像下旋转楼梯一样利用树枝跳到了地上。红衣凤头鸟通常喜欢待在树木的安全掩护中。它是一只鲜红色的鸟,在野外很容易发现它。如果一只鹰看到它,它可能会成为别人的晚餐。于是,红衣凤头鸟沿着那块地的边缘跳来跳去,寻找草丛中的虫子。它没有离开它的安全树太远。
