Abstract We study the propagation of shear horizontal waves between the interface of piezoelectric and piezomagnetic half-spaces with a magneto-electro-mechanical imperfect contact. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and a inductor, respectively. A general expression for the dispersion relation not reported previously in literature is given in an explicit form, with the diverse limit cases analysed in detail. In some of these limit cases, new expressions are also obtained which predict the existence of interfacial waves. In the other cases, when already reported results exist, a comparison with them is done. Some physical interpretations are derived from the limit cases. The influence of mechanical, electrical and magnetical imperfect contacts are shown in some numerical examples. 相似文献

ABSTRACTDescartes did not use the terms ‘primary’ and ‘secondary’ qualities, but a similar distinction emerges from his texts: certain qualities of objects (such as size and shape) are intrinsic properties of matter, whereas others (like colours and smells) are products of the interaction with a perceiver. A common interpretation states that the division between primary and secondary qualities is explained by the way in which we are acquainted with them: an idea of a primary quality is similar to its physical causes, and it is clearly and distinctly perceived by the intellect. An idea of a secondary quality is dissimilar to its physical causes and it is obscurely and confusedly perceived by the senses. This view receives the name of ‘bifurcation reading’ (Simmons, A. ‘Descartes on the Cognitive Structure of Sensory Experience’. Philosophy and Phenomenological Research, LXVII, no. 3 (November 2003)). While it integrates well some textual occurrences, it creates a problematic fragmentation within single acts of perception. This paper contends that this reading is incorrect. It presents several arguments for the claim that the distinction of qualities is due to the different ways in which our ideas of them misrepresent their physical causes. Then, Descartes’ dissimilarity thesis between physical objects and our ideas of them remains a structural feature of his theory of sensory perception and not a local phenomenon affecting only ideas of secondary qualities. 相似文献

Empirical studies of personality traits in creative writers have demonstrated mixed findings, perhaps due to issues of sampling, measurement, and the reporting of statistical information. The goal of this study is to quantify the personality structure of aspiring creative writers according to a modern hierarchal model of trait personality. A sample of aspiring writers (n = 93) and nonwriters (n = 114) completed the Big Five inventory. Correlations with personality were carried out at three levels: the Big Five traits, the two higher-order factors (stability and plasticity), and the more detailed facet-level. Consistent with past research, creative writers scored higher on trait openness. Extending past work, the hierarchical analysis also revealed novel correlates for the higher-order meta-traits (stability and plasticity) and some of the lower-order facets (aesthetics, ideas, activity, assertiveness, and depression). Individuals with higher scores on agreeableness, stability, and assertiveness were less likely to be aspiring writers. The likelihood of being a writer also decreased with age. Taken together, these findings indicate that aspiring creative writers differ from nonwriters in trait personality, with differences emerging at all levels of the personality hierarchy. 相似文献

This research aims to analyze the relationship between sociocultural values and human food preferences. The latter, as shown in this paper, are greatly influenced by cultural identity. This work stems from a theoretical context that originated in Europe and the United States towards the mid‐twentieth century, within the field of the anthropology of food. A qualitative and quantitative analysis has been performed in the Comunidad Autónoma de Aragón (Spain). Research methods include focus groups, in‐depth interviews, participant observation, and a questionnaire that was handed out to a representative sample of the Aragonese population (816 people over 21 years of age; confidence level of 95.5% and error margin of ±3.5). Regarding the research outcome, a highly significant qualitative and quantitative connection has been found between food selection and cultural identity. In other words, people prefer to consume foods that are symbolically associated with their own culture, in order to reinforce their sense of belonging. Although this study has been carried out in Aragón, it is our belief that the results can be generalized to other areas. The originality and interest of our findings are notable considering that, to date, few works have analyzed the sociocultural factors motivating food behavior. Moreover, these results could be used by public and private organizations to meet objectives such as health promotion and product marketing. 相似文献

Der Aufsatz schildert den platonisierenden Antipsychologismus welchen Bolzano, der junge Brentano, Twardowski, Meinong, der Husserl der Logischen Untersuchungen, Frege, der Russell der Jahrhundertwende und der junge Wittgenstein philosophisch vertraten, und versucht eine soziologische und ideologiekritische Interpretation sowohl dieser Einstellung als auch derjenigen des traditionellen Psychologismus des achtzehnten Jahrhunderts. Der Platonismus des neunzehnten und zwanzigsten Jahrhunderts wird als ein Ausdruck fiir ‐ oder vielmehr als eine Reaktion gegen ‐ den Verfall der klassischen burgerlichen Werte aufgefaBt. In Wittgensteins Tractatus spielen Elemente sowohl eines platonisierenden Antipsychologismus wie auch eines relativistischen, verhaltensphanomenologisch orientierten Antipsychologismus eine Rolle: dieses Werk wird also als eine grelle Manifestation des Uberganges von der klassischen zur spatbiirgerlichen Weltanschauung, als ein Obergang vom Glauben an ewige Wahrheiten zur Hinnahme einer Gebrauchs‐Theorie der Bedeutung und deren Konsequenzen interpretiert. 相似文献

The effectiveness of the mnemonic-keyword method was investigated in 4 experiments in which participants were required to learn the lst-language (L1, Spanish) equivalents of a list of 30 2nd-language words (L2, Latin). Experiments 1 (adolescents) and 2 (adults) were designed to assess whether the keyword method was more effective than the rote method; the researcher supplied the keyword, and the participants were allowed to pace themselves through the list. Experiments 3 (adolescents) and 4 (adults) were similar to Experiments 1 and 2 except that the participants were also supplied with a drawing that illustrated the relationship between the keyword and the L1 target word. All the experiments were performed with groups of participants in their classrooms (i.e., not in a laboratory context). In all experiments, the rote method was significantly more effective than was the keyword method. 相似文献

The authors’ aim was to examine whether short-term kinesthetic training affects the level of sensorimotor rhythm (SMR) in different frequency band: alpha (8–12 Hz), lower beta (12.5–16 Hz) and beta (16.5–20 Hz) during the execution of a motor imagery task of closing and opening the right and the left hand by experts (jugglers, practicing similar exercises on an everyday basis) and amateurs (individuals not practicing any sports). It was found that the performance of short kinesthetic training increases the power of alpha rhythm when executing imagery tasks only in the group of amateurs. Therefore, kinesthetic training may be successfully used as a method increasing the vividness of motor imagery, for example, in tasks involving the control of brain–computer interfaces based on SMR. 相似文献

We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population. 相似文献
