Does music induce emotion? A theoretical and methodological analysis.

Is music ubiquitous in part because it is causally linked to emotion? In this article, a comprehensive theoretical and methodological reevaluation is presented of a classical problem: The direct induction of emotion by music (M→E). The author's Prototypical Emotion-Episode Model (PEEM) is used in the conceptual critique. A close scrutiny of the major published studies, and the author's new data regarding some substantive and methodological issues in several of these, reveal weak support for the M→E model. The conclusion seems justified that music may induce low-grade basic emotions through mediators, such as dance and cognitive associations to real-world events. However, it is suggested--on the basis of the recently developed Aesthetic Trinity Theory (ATT; Kone?ni, 2005) and its further development in the present article--that being moved and aesthetic awe, often accompanied by thrills, may be the most genuine and profound music-related emotional states.

根据热节位置的变化改进侧盖铸件的工艺

为简化高牌号灰铸铁侧盖铸件的铸造工艺,不用砂芯,将分型面下移,结果引起了缩松缺陷,废品率高达50%左右。对引起缩松的原因进行了分析,并采取了相应的工艺措施,上下底面同时加冷铁,消除了缩松缺陷。     

呋喃树脂砂在大型球铁件上的生产实践

树脂砂铸造工艺应用于大型球墨铸铁件整体铸造柴油机缸体、曲轴生产上消除整铸缸体“粘砂”、“缩松”、“尺寸偏差大”及曲轴“粘砂”、“浇不足”、“漏铁液”等铸造缺陷，具有明显的效果。     

减少QT400-15飞轮壳缩孔、缩松的措施

介绍了QT400-15飞轮壳铸件原生产工艺所产生的缩孔、缩松情况.分析认为缩孔、缩松的主要原因是:铸件厚壁处及孤立热节处得不到补缩,以及铸型紧实度偏低.通过在外砂型和砂芯上加冷铁、增加补缩冒口、提高铸型紧实度、合理控制铁液化学成分和浇注温度等措施,使该部位的缩孔、缩松基本消除,从而使铸件的综合废品率降至6％左右.     

CAE技术在轴承箱体铸造工艺优化中的应用

利用华铸CAE软件对YL14000B型烟机轴承箱体的充型凝固过程进行了模拟分析,预测了该铸件原铸造工艺存在冒口过大而导致的补缩过剩、后轴承座热节处存在集中缩孔、底座热节处存在疏松等缺陷.通过采取减小冒口尺寸、增加热节处内冷铁数量和加宽补缩通道等措施;再次进行CAE数值模拟,发现上述缺陷得到了有效消除.实际生产结果表明,冒口根部无集中缩孔,铸造工艺出品率由61%提高到了71%,节约钢液660 kg,降低了生产成本,铸件质量也得到了提高.

On personality and piloerection: Individual differences in aesthetic chills and other unusual aesthetic experiences.

Relatively little is known about aesthetic chills, the experience of goose bumps and shivers in response to the arts. The present study explored how often people report such experiences and what people who often experience them are like. After noting which domain of the arts they encountered most often in daily life, young adults (n = 188) rated how often they experienced aesthetic chills and related states. Latent variable models suggested three latent factors—aesthetic chills, feeling touched, and absorption—that shared a higher-order factor. As expected, people high in openness to experience and expertise in the arts consistently reported experiencing aesthetic chills more often. The Big Five personality factors accounted for about half of the variance, whereas cognitive and demographic variables were relatively unimportant. The individual-differences approach thus seems like a promising complement to experimental work on aesthetic chills. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
