Tensile tests were performed on precracked Cr–Mo martensitic steel (C: 0.38, Si: 0.22, Mn: 0.84, P: 0.024, S: 0.021, Ni: 0.08, Cr: 1.11, Mo: 0.15, Cu: 0.12, Fe: bal. (wt%)) specimens at various strain rates (ranging from 6.5 × 10?8 s?1 to 1.0 × 10?4 s?1) in high-pressure (95 MPa) hydrogen and helium atmospheres. Irrespective of the strain rate, the tensile strength in the helium atmosphere was 1400 MPa. In the hydrogen atmosphere, the tensile strength decreased to less than 600 MPa at a strain rate of 2.0 × 10?5 s?1. However, the tensile strength increased to 900 MPa when the strain rate was decreased to 6.5 × 10?8 s?1. This recovery of the tensile strength was because of the decrease in the local stress in the vicinity of the precrack because of hydrogen. 相似文献

The interviews of 10 female counseling psychology doctoral students regarding their views about meaning in life (MIL) were analyzed using consensual qualitative research. The participants defined MIL as goals or purposes, were actively involved in searching for meaning, and believed that MIL had been stimulated by life-changing experiences and culture. On a personal level, they gained meaning from relationships, personal growth, and religion/spirituality. On a professional level, they gained meaning from providing therapy, conducting research, and teaching. As therapists, participants approached MIL indirectly by asking about client goals/motivations or by focusing on other clinical problems that if resolved would enhance MIL. Implications for doctoral training and for psychotherapy are offered. 相似文献

In the lead-up to Australia committing military resources and personnel to the coalition opposing the Islamic State in the Levant (ISIL), Prime Minister Tony Abbott consistently categorized the al-Qaeda splinter group as a “death cult.” Examining Abbott's official rhetoric on ISIL and the threat it poses to Australia and the world, this article argues that his use of the term “death cult” reflects patterns in Western political demonology and demonizing enemies, namely, creating adversaries as monsters by highlighting the atrocities they commit in order to garner support for (often lethal) actions against them. In traditional political demonology, establishment representatives often target minority or marginal groups as these pariahs. However, in demonizing ISIL, Abbott deliberately made distinctions between it and its members and the majority of Muslims, including Australian Muslims, and utilized political demonology differently. In so doing, he affirmed this religious minority's status within the parameters of Australian citizenship. This is indeed commendable. However, Abbott rarely mentioned Muslims outside of references to terrorism. Despite the fact that Abbott acknowledges that only a comparative handful of Muslims are indeed violent, he has not yet fully engaged with the broader notions of Australian Muslims’ contributions to Australian society and their citizenship. 相似文献

Economic and psychological studies have determined the tendency to improve cooperation in initial interactions in which people are required to contribute in public good games. The current study examined the behavioural changes of individuals during finite interaction times. Participants were invited to make decisions twice in a step‐level public good game, and their belief in achieving the collective interest was measured. Participants were divided into three groups based on their first decisions. Results showed that high contributors demonstrated high levels of contribution in their subsequent interactions, whereas low and equal contributors increased their levels of contribution after the initial interaction. Additionally, the cooperative level of low contributors increased along with their cooperative belief. The theoretical and practical implications of changes of behaviour and belief in repeated social dilemmas were identified. 相似文献

In this essay, I discuss the continuing relevance of Jesus ACTED UP in three dimensions: the pastoral, the academic, and the self-critical. Framing the essay with personal reflections, I first describe how the book continues to meet the pastoral needs of the LGBTIQ community, especially by channeling our rage in a constructive way. I then describe how the book continues to be relevant to the academic community by speaking truth to power. Finally, I describe how the book continues to speak to the LGBTIQ community by cautioning against a turning inwards of oneself (i.e. incurvatus in se). I conclude the essay with a personal note of gratitude to Bob Shore-Goss for the ways in which he personally embodies these three dimensions in his life and work. 相似文献

We intended to study unaddressed psychosocial and spiritual needs among older people (of at least 65 years of age) living in nine residential/nursing homes in Bavaria in Southern Germany. We conducted an anonymous cross-sectional study with standardised questionnaires (i.e., Spiritual Needs Questionnaire, Brief Multidimensional Life Satisfaction Scale, Schedule for Meaning in Life Evaluation, etc.). Religious needs were predicted best by residents’ religious trust. Existential needs and inner peace needs correlated moderately with grief, and were predicted best by family/social support needs. All members of an interdisciplinary team should be trained in the specific competence of recognising older people's unmet spiritual needs. When these needs are recognised, caregivers and relatives have the chance to react. 相似文献

This article details a year-long project in which the author created a series of 365 sandtrays and journaled about them as a professional and personal growth project. The author shares professional and personal lessons learned from this experience and describes how reflective practices can be used as a method to improve clinical work. 相似文献

Teen dating abuse (TDA) is a serious public health problem affecting almost half of all adolescents in the United States. Because of the developmental characteristics of adolescence such as identity confusion and rejection of adult authority figures, counseling adolescents who are experiencing TDA can be particularly challenging. This article describes the types of abuse, the early warning signs of abuse, and effective strategies that mental health counselors can use to counsel and educate teen victims of TDA and others. 相似文献

This pilot study evaluated whether a creative arts therapy program delivered through a 2-week summer day camp benefited children’s support networks and improved their general wellness. Camp staff completed ratings on the behavior of 11 children. Eleven parents (10 mothers) completed ratings on their children’s behavior. Surveys were utilized; data were analyzed using Wilcoxon t tests. Results demonstrated that camp staff observed the most significant improvements in children’s behaviors and relationships. Results of this study indicate that a social skills therapy program delivered through a creative arts summer camp can be beneficial to young children. Furthermore, these results were found during an intense, yet brief, period of time. 相似文献
