We study the propagation of shear horizontal waves between the interface of two piezoelectric materials with an electro-mechanical imperfect contact. Mechanical and electrical imperfections are modeled by means of a spring and a capacitor, respectively. The corresponding mathematical expressions for the imperfect contact are given in this article. The system of differential equations for the waves in the considered half-space is derived and the associate solutions are found. A general expression for the dispersion relation, not reported previously in the literature, is given in an explicit form, with the diverse limit cases analyzed in detail. In some of these limit cases, new expressions are also obtained, which predict the existence of interfacial waves. In the other cases, where already reported results exist, a comparison with them is done. Some physical interpretations are derived from the limit cases. The influence of mechanical and electrical imperfect contacts are shown in some numerical examples.  相似文献

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.  相似文献

The aim of this study was to examine the associations of control and vividness of mental imagery on performance in several components of in-depth drawing in a sample of fine arts undergraduates. The sample consisted of 56 second-year undergraduates (44 women and 12 men, mean age = 21.18 years) from the Fine Arts Faculty of Vigo University, Pontevedra, Spain. Participants were required to undertake a plastic art assignment focusing on the pictorial representation of space. Participants scoring high on the image control test obtained higher scores on the spatial analysis and in the formal construction of a work than participants with poor image control. Further research involving spatial image performance tests and mental image rotation tests is proposed.  相似文献

Some argue that the medical model and the experimental design that underlies the use of treatment manuals to prove the efficacy of a psychotherapeutic treatment clashes with the theoretical basis of family therapy. From the point of view of the empirically supported treatments (ESTs) movement, treatment manuals are the operationalization of the independent variable in a clinical trial; the therapist is only part of the procedure and the therapeutic relationship is a confounding variable. Applying that logic to the practice of family therapy might be considered a heresy. This article argues that paradoxically, this heresy has a lot to offer the practice of family therapy. Research is the best way to answer questions like ‘how does family therapy work?’ ‘What makes ‘good therapy’ good?’ ‘Do therapists do what they say they do'? This article recommends an alternative framework for integrating ESTs into practice by proposing empirically informed guides to practice which, being less formulaic, encourage process‐outcome research, are coherent with the systemic model and do not constrain the therapist's creativity. Such guidelines allow therapists to use manuals flexibly so that they deepen the understanding of the process of therapy. We encourage you to listen to the JFT Editor, Mark Rivett, as he interviews the author on Manuals in the Practice and Research of Family Therapy.

Most theories of persuasion predict that limited ability and motivation to think about communications should increase the impact of source credibility on persuasion. Furthermore, this effect is assumed to occur, regardless of whether or not the recipients have prior attitudes. In this study, the effects of source credibility, ability, and motivation (knowledge, message repetition, relevance) on persuasion were examined meta-analytically across both attitude formation and change conditions. Findings revealed that the Source Credibility × Ability/Motivation interaction emerged only when participants lacked prior attitudes and were unable to form a new attitude based on the message content. In such settings, the effects of source credibility decayed rapidly. The implications of these findings for applied communication campaigns are discussed.  相似文献

We conducted a content analysis of online job application forms used by companies listed on the Spanish Stock Exchange (i.e., Bolsa de Madrid). We collected data from 76 companies in 2005 and then again for 66 of these companies in 2009. We coded the type of information required on the application forms based on 24 categories related to potential illegal discrimination and personnel selection social context issues (i.e., fairness, intrusiveness, and privacy). Results indicated that the relative frequency of the 24 information categories has remained stable from 2005 to 2009. Moreover, averaging 2005 and 2009 results, a large percentage of companies require information that can be used for illegal discrimination and can be perceived as unfair, intrusive, and invasive of applicants' privacy such as age or date of birth (87%), nationality (61%), marital status (48%), place of birth (57%), passport number (47%), a photograph (23%), and number of children (11%). Our results document a science–practice gap in e‐recruitment because scholarly research suggests that requesting these types of information leads to negative applicant reactions ranging from negative perceptions and emotions to actually initiating legal action against the recruiting firm. Our results also point to e‐recruitment as an area that could be targeted as a good collaboration topic between scientists and practitioners because the resulting research has the potential to make important contributions toward bridging the science–practice gap.  相似文献

Estrous behavior in rodents is triggered by the binding of progesterone (P) to its intracellular receptor (PR). Non-steroidal agents (i.e., gonadotropin-releasing hormone, noradrenaline, dopamine and others), acting at the membrane, can facilitate estrous behavior in estrogen-primed rats. This action is mediated through the generation of second messengers (cyclic AMP, cyclic GMP, calcium) which, in turn, phosphorylate through diverse kinase systems (protein kinases A, G or C) either the PR or associated effector proteins linking the PR to the trans-activation machinery. P or its metabolites also activate cyclic AMP-signaling pathways by acting directly on the membrane or by modulating neurotransmitter release. Molecular processes resulting from second messenger signaling pathways and those from the progesterone-RP interaction synergize to elicit a full behavioral response.  相似文献

A variety of clinical and experimental data suggest that many individuals who report abusive and traumatic experiences also report a wide array of dissociative and other psychopathological symptoms. In this study, 198 Puerto Rican undergraduate students participated in a study to examine the possible relationship between different types of traumatic experiences and the self-report of dissociative experiences, depressive symptoms, and general psychopathology. Another aspect of this study was the examination of the psychometric properties of the Dissociative Experiences Scale (DES) in a Latino sample. Results supported the hypothesis that those individuals who reported frequent and severe traumatic experiences were also the most likely to experience psychological malaise and scored higher on the DES. Of interest was the finding that the psychometric characteristics of the DES are consistent with those reported in the United States and other countries. The authors conclude that individuals with a marked history of trauma and abuse are more likely to use dissociative defenses as a coping response.  相似文献
