There is often something wrong with merely promising to try to φ. In this article I explain what is wrong with such promises. I argue that a promise to try to φ, when it is entirely up to us to φ, is always wrong because it hides a possible choice under the veil of our susceptibility to circumstances beyond our control. I furthermore argue that this is often also the case when matters are not entirely up to us. Finally, I contend that sometimes the promise to try places undue burdens on the promisee.  相似文献

War-traumatized refugee adolescents are a vulnerable and understudied group. This study of two different groups of war-traumatized youth (N = 77) resettled in Sweden (newly arrived refugee adolescents, n = 42, 13–19 years, and settled students with childhood war experiences, n = 35, 11–18 years) evaluated their war experiences, refugee journey, general trauma exposure, posttraumatic stress symptoms, and dissociative experiences. Both groups had experienced many traumas and a substantial proportion reported levels consistent with posttraumatic stress (71% in the newly arrived group and 34% among the settled students) and dissociation (36% and 23%, respectively). The study also provides information about the type of adverse events experienced by war-refugee adolescents, including their own subjective appraisals of the worst events. The results show that the extent of trauma exposure and posttraumatic and dissociative symptomatology among refugee adolescents are considerable even after a period of resettlement, a finding that has educational, clinical, and social implications.  相似文献

Abstract : Emotion regulation (ER) and coping strategies were compared in 242 pedagogical students from the Faculty of Education, University of Ljubljana, with different attachment styles: secure (51.3%), fearful (31.9%), preoccupied (14.2%), and dismissive (2.7%). The students’ ages ranged from 18 to 24 years ( M = 19.02; SD = .92), and the majority were female (95.0%). They completed three questionnaires assessing their attachment styles and their use of ER and coping strategies. It was determined that the students used the majority of ER and coping strategies sometimes. Somewhat different patterns in the use of ER and coping strategies were, however, present in each attachment‐based group. Significant differences between these groups appeared in their use of the ER strategies of social support, suppression, and comfort eating, and in the coping strategies of seeking social support and escaping or avoiding stressful situations.  相似文献

Abstract

The dependence of the normal-state resistivity, resistive superconducting transition (T c, ΔT c), and of the upper critical-field slope (dH c2/dT|T=Tc) on density has been investigated for several YBa2Cu3O9-x(x?2.1) samples. The resistivity decreases rapidly with increasing density, whereas T c and ΔT c are rather insensitive to a change in density. dH c2/dT|Tc depends sensitively on the preparation conditions. The implications of these results both for the evaluation of the parameters relevant to the understanding of the nature of superconductivity and for the technological applications of granular superconductors are briefly discussed.  相似文献
