The deformation behaviour of the γ′ precipitate in a directionally solidified nickel-based superalloy is investigated using microscopic observations after tensile testing at room temperature. It is found that coarse γ′ precipitates (604 nm) are sheared by strongly coupled dislocations, and some γ′ precipitates are elongated to approximately 3–6 times of their original lengths. It reveals that, at room temperature, the γ′ precipitate within the experimental superalloy has a significant plastic deformation capacity in comparison with Ni3Al bulk alloys. Based on the experimental observations, the extraordinary plastic behaviour of the γ′ precipitate is analysed. 相似文献

Work Engagement of Dual-Working Couples: Dissimilarity and Its Relation to Both Partners’ Well-Being
Maša Tonković Grabovac Svjetlana Salkičević Ajana Löw Stanić 《Current psychology (New Brunswick, N.J.)》2016,35(4):595-605
Work engagement is a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption. Work engaged individuals not only function better at work, but also transfer these benefits to home - research has shown that work engagement crosses over between marital partners. In previous studies on crossover, this phenomenon was evidenced only by significant correlation between self-reports of partners’ work engagement, while measures of dissimilarity between partners were completely ignored. However, work engagement dissimilarity - with one partner being highly enthusiastic and immersed in his/her work and the other one lowly - could be related to some aspects of both partners’ well-being and might improve its prediction. Hence, the goal of this study was to examine work engagement dissimilarity within dual-earning couples. In addition to self-report measures, we collected partners’ ratings of work engagement and its subdimensions as well. The data collected on 178 dual-working Croatian couples showed significant correlation of overall work engagement, vigor, dedication and absorption between various pairs of self- and other-ratings measures (partners’ self-ratings; self-ratings and partner’s ratings; and partner’s self-ratings and his/her ratings of work engagement of the partner). Moreover, difference in self-ratings and ratings of partner’s work engagement showed negative correlation with life satisfaction of both partners, suggesting that work engagement dissimilarity has a potential to be related to some aspects of partners’ well-being. 相似文献

Participants typically process same-race faces more quickly and more accurately than cross-race faces. This deficit is amplified in the right hemisphere of the brain, presumably due to its involvement in configural processing. The present research tested the idea that cross-race contact tunes cognitive and perceptual systems, influencing this asymmetric race-based deficit in face processing. Participants with high and low levels of contact performed a lateralized recognition task with same- and cross-race faces. Replicating prior work, participants with minimal contact showed cross-race deficits in processing that were larger in the right hemisphere. For participants with more contact, this lateralized deficit disappeared. This effect of contact seems to be independent of race-based attitudes (e.g., prejudice). 相似文献

In this article, we trace and elucidate Heidegger’s radical re-thinking on the relation between science and technology from about 1940 until 1976. A range of passages from the Gesamtausgabe seem to articulate a reversal of the primacy of science and technology in claiming that “Science is applied technology.” After delving into Heidegger’s reflection on the being of science and technology and their “coordination,” we show that such a claim is essentially grounded in Heidegger’s idea that “Science and technology are the Same [das Selbe].” In addition, we argue that, although different ontic epochs can be distinguished in the evolvement of science and/or technology, for Heidegger there is only one unique ontological Epoch of modernity that encompasses various ontic epochs. Therefore, the change from an “epoch of objectivity” to an “epoch of orderability [Bestellbarkeit]” cannot be considered to be an ontological shift. Furthermore, it is not right to ascribe to Heidegger the view that the development of quantum physics signals the beginning of a new ontological Epoch. 相似文献

When Interrogative Self‐talk Improves Task Performance: The Role of Answers to Self‐posed Questions 下载免费PDF全文
Małgorzata M. Puchalska‐Wasyl 《Applied cognitive psychology》2014,28(3):374-381
Nearly all the self‐talk cues studied so far have been self‐statements. However, the findings of Senay, Albarracin, and Noguchi suggest that interrogative self‐talk produces better task performance than declarative one. Two of the experiments reported here were meant to replicate that study, but the expected differences were not confirmed. Experiment 3 showed that if a self‐posed question about future behavior was answered positively, task performance was better than in groups exposed either to the self‐statement ‘I will do it’ or to a negative answer following the question. However, these differences occurred only in those who self‐reported the awareness of the impact of self‐talk on their thought processes. This effect and the possible reasons why between‐group differences were not found in Experiments 1 and 2 are discussed. An alternative explanation for the results of Experiment 3 is also proposed beside that stressing the impact of internal answer. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Even at the end of life, testing cancer patients for inherited susceptibility may provide life-saving information to their relatives. Prior research suggests palliative care inpatients have suboptimal understanding of genetic importance, and testing may be underutilized in this clinical setting. These conclusions are based on limited research. This study aimed to estimate genetic testing prevalence among high-risk palliative care patients in a National Cancer Institute-designated comprehensive cancer center. We also aimed to understand these patients’ understanding of, and attitudes toward, hereditary cancer testing and DNA banking. Palliative care in-patients with cancer completed structured interviews, and their medical records were reviewed. Among patients at high risk for hereditary cancer, we assessed history of genetic testing/DNA banking; and related knowledge and attitudes. Among 24 high-risk patients, 14 (58.3%) said they/their relatives had genetic testing or they had been referred for a genetics consultation. Of the remaining 10 patients, seven (70%) said they would “probably” or “definitely” get tested. Patients who had not had testing were least concerned about the impact of future testing on their family relationships; two (20%) said they were “extremely concerned” about privacy related to genetic testing. Of patients without prior testing, five (50%) said they had heard or read “a fair amount” about genetic testing. No high-risk patients had banked DNA. Overall, 23 (95.8%) said they had heard or read “almost nothing” or “relatively little” about DNA banking. Written materials and clinician discussion were most preferred ways to learn about genetic testing and DNA banking. Overall, this study demonstrates underutilization of genetics services at the end of life continues to be problematic, despite high patient interest. 相似文献
