Recently, a lot of attention has been given to a mechanical device known as the inerter. It is a mechanical component that can be compared to a capacitor with two ungrounded terminals in the mechanical-electrical systems analogy. In this paper, it is shown that although the concept of an inerter as a separate mechanical element is relatively new, there are several well-established vibration isolation systems that exhibit similar behavior to a simple lumped parameter system containing an inerter. Through a review of the literature, a link is established between the old and new ideas. Furthermore, a comparison between the systems is carried out using the quantities of mechanical impedance and displacement transmissibility. The advantages and disadvantages of using the inerter in vibration isolation are discussed, and a simple way of improving the high-frequency performance without severely degrading the low-frequency performance is described. 相似文献

The Rural Engineering Department (Technical University of Madrid) ran three competence surveys during the 2006–2007 and 2007–2008 academic years and evaluated: (1) the competences gained by agricultural engineer's degree and agricultural technical engineer's degree students (360 respondents); (2) the competences demanded by agricultural employers (50 farming sector employers); (3) competences required by farming sector professionals and former students (70 professionals). The surveys show significant differences between what competences agricultural employers require of graduates and the competences they acquire during their agricultural engineering degree courses. Recruiters are looking for generic competences such as the ability to coordinate groups and place less importance on knowledge of engineering, biology, applied economics and legislation. Of the computer-related competences, those most in demand by sector professionals were related to the use of Microsoft Office/Excel (used by 79% of professionals). Surveys were used to redesign some subjects of the degrees. 相似文献

The main goal of the 2009 UNESCO Framework for Cultural Statistics is to facilitate comparisons through a common understanding of culture and the use of standardized definitions and classifications. This review contains an in-depth analysis of the 2009 Framework's contribution to the existing literature on measuring the economic impact of culture, and it concludes by suggesting future avenues of research. By achieving international consensus on the concept of culture and its measurement, we will be able to progress in our studies of the competitive advantages that allow cultural firms to generate wealth nowadays. 相似文献

The utility of three-dimensional (3D) printed models for medical education in complex congenital heart disease (CHD) is sparse and limited. The purpose of this study was to evaluate the utility of 3D printed models for medical education in criss-cross hearts covering a wide range of participants with different levels of knowledge and experience, from medical students, clinical fellows up to senior medical personnel. Study participants were enrolled from four dedicated imaging workshops developed between 2016 and 2019. The study design was a non-randomized cross-over study to evaluate 127 participants' level of understanding of the criss-cross heart anatomy. This was evaluated using the scores obtained following teaching with conventional images (echocardiography and magnetic resonance imaging) versus a 3D printed model learning approach. A significant improvement in anatomical knowledge of criss-cross heart anatomy was observed when comparing conventional imaging test scores to 3D printed model tests [76.9% (61.5%–87.8%) vs. 84.6% (76.9%–96.2%), P < 0.001]. The increase in the questionnaire marks was statistically significant across all academic groups (consultants in pediatric cardiology, fellows in pediatric cardiology, and medical students). Ninety-four percent (120) and 95.2% (121) of the participants agreed or strongly agreed, respectively, that 3D models helped them to better understand the medical images. Participants scored their overall satisfaction with the 3D printed models as 9.1 out of 10 points. In complex CHD such as criss-cross hearts, 3D printed replicas improve the understanding of cardiovascular anatomy. They enhanced the teaching experience especially when approaching medical students. 相似文献

This paper aims to extend existing theorisations around the notion of public narratives by analysing their regulatory effects under intensified market conditions. My analysis suggests that public narratives constitute a liminal space, one that it is not exclusively real or imaginary, factual or normative, but that simultaneously affects and is affected by vernacular practices and wider discursive structures. However, this paper argues that, under extreme conditions, these public narratives become a rigidifying space with homogenising/normalising effects. To do this I look at a set of ‘obligatory scenes’ captured in tales of success and struggle of teachers, parents and students in popular newspapers and fringe media in Chile. These accounts share a common ground: national assessment as a framework of intelligibility for the practices of parents, teachers and students. The central claim of this paper is that under intensified market conditions the scenes captured in these publicly available stories become ‘obligatory’ storylines, and their protagonists idealised policy subjects. 相似文献

European Frame for Higher Education has led universities to adapt their teaching schemes. Degrees must train students in competences including specific and cross-curricular skills. Nevertheless, there are important limitations to follow skill improvement through the consecutive academic years. Final-year dissertation (FYD) offers the opportunity to assess these aspects so linked to the professional requirements. The experience reported here offers an alternative methodology for the FYD in order to reinforce cross-curricular skills and substitute the classic final evaluation schemes. A new protocol for the FYD was defined and tested in the Degree in Human Nutrition and Dietetics, with the participation of students and lecturers from different disciplines. The new methodology included collaborative activities that required students active implication and participation. New cross-curricular skills not considered before were included and evaluated in a continuous way: analysis and critical attitude, as well as team working. Obtained data revealed an improvement over cross-curricular skills. Student–student cooperation resulted in significant contributions to enhance FYD quality. The new methodology was satisfactorily valued by students. The main keys for the successful implementation of this protocol were the followings: encouragement of teachers and students, coordination, information and communication technologies, and clear guidelines. 相似文献
