Who is the engaged citizen? Correlates of secondary school students’ concepts of good citizenship

The opinions about what characterises a good citizen are diverse, yet survey research usually employs variable-centred analytical strategies to examine people’s concepts of good citizenship. The present study builds on a person-centred approach towards good citizenship and validates previously identified types of good citizenship among Australian secondary school students. Following an in-depth characterisation of these types by sociodemographic variables and civic attitudes, this study incorporates multinomial regression analysis to take a closer look at very extreme but practically important patterns. These analyses suggest that students need to believe in the value of civic action to become political enthusiasts and not politically alienated. Civic knowledge may prevent political alienation; however, it is not the ultimate solution as it is negatively correlated with political enthusiasm when controlling for multiple predictors. The results are discussed with respect to their significance for civics and citizenship teaching and learning.     

Carrier phase shifted SPWM based on current sourced multi-modular converter for active power filter

INTRODUCTION iout = i1 (4) Active power filter (APF) (Grady et al., 1990) The resulting iout is sinusoidal and high quality.is a power conversion system for compensating the In this way, APF could provide the harmonic cur-harmonic and reactive power from the nonlinear rent, which is an essential requirement of theload.…     

Evaluation of creative problem-solving abilities in undergraduate structural engineers through interdisciplinary problem-based learning

For a structural engineer, effective communication and interaction with architects cannot be underestimated as a key skill to success throughout their professional career. Structural engineers and architects have to share a common language and understanding of each other in order to achieve the most desirable architectural and structural designs. This interaction and engagement develops during their professional career but needs to be nurtured during their undergraduate studies. The objective of this paper is to present the strategies employed to engage higher order thinking in structural engineering students in order to help them solve complex problem-based learning (PBL) design scenarios presented by architecture students. The strategies employed were applied in the experimental setting of an undergraduate module in structural engineering at Queen’s University Belfast in the UK. The strategies employed were active learning to engage with content knowledge, the use of physical conceptual structural models to reinforce key concepts and finally, reinforcing the need for hand sketching of ideas to promote higher order problem-solving. The strategies employed were evaluated through student survey, student feedback and module facilitator (this author) reflection. The strategies were qualitatively perceived by the tutor and quantitatively evaluated by students in a cross-sectional study to help interaction with the architecture students, aid interdisciplinary learning and help students creatively solve problems (through higher order thinking). The students clearly enjoyed this module and in particular interacting with structural engineering tutors and students from another discipline.     

从“积极政府”到“自制政府”:新时代现代大学治理中的政府画像

政府干预是影响现代大学治理的重要变量。作为一种干预形态,"积极政府"的定位源于特定的时代命题,其行动产生了预设的积极效用,有力推进了中国大学的现代化进程,但同时也带来了制度赶超、政策过剩、大学能力单一等消极效应。新时代的国家治理转型为政府善治大学提出了新愿景,面对如何营造有利于大学内涵式发展的外部环境、如何避免现代大学制度落地过程中的悬置、如何引导大学真正服务社会等挑战,政府应从"积极介入"走向"自我节制",通过规范介入的空间、减少介入的主体、变革介入的方式、降低介入的动力等策略描绘出理想的"自制政府"画像。

The colloquial approach: An active learning technique

This paper addresses the very important problem of the effectiveness of teaching methodologies in fundamental engineering courses such as transport phenomena. An active learning strategy, termed the colloquial approach, is proposed in order to increase student involvement in the learning process. This methodology is a considerable departure from traditional methods that use solo lecturing. It is based on guided discussions, and it promotes student understanding of new concepts by directing the student to construct new ideas by building upon the current knowledge and by focusing on key cases that capture the essential aspects of new concepts. The colloquial approach motivates the student to participate in discussions, to develop detailed notes, and to design (or construct) his or her own explanation for a given problem. This paper discusses the main features of the colloquial approach within the framework of other current and previous techniques. Problem-solving strategies and the need for new textbooks and for future investigations based on the colloquial approach are also outlined.     

An appraisal of an online tutorial system for the teaching and learning of engineering physics in conjunction with contextual physics and mathematics,and relevant mathematics

The number of students entering engineering schools in Australian universities has increased tremendously over the last few years because of the Australian Federal Government's policy of increasing the participation rates of Higher School Certificate students and students from low social economic status backgrounds in the tertiary sector. They now come with a diverse background of skills, motivations and prior knowledge. It is imperative that new methods of teaching and learning be developed. This paper describes an online tutorial system used in conjunction with contextual physics and mathematics, and the revision of the relevant mathematical knowledge at the appropriate time before a new topic is introduced in the teaching and learning of engineering physics. Taken as a whole, this study shows that students not only improved their final examination results but there was also an increase in the retention rate of first-year engineering students which has financial implications for the university.     

A disc-type magneto-rheologtic fluid damper

A disc-type magneto-rheological fluid damper operating in shear mode is proposed in this paper, which is based on the special characteristics of the magneto-rheological (MR) fluid with rapid, reversible and dramatic change in its rheological properties by the application of an external magnetic field. The magnetic field of the disc-type MR fluid damper is analysed by the finite element method; the controllability of the disc-type MR fluid damper on the dynamic behaviour of a rotor system; and the effectiveness of the disc-type MR fluid damper in controlling the vibration of a rotor system, are studied in a flexible rotor system with an overhung disc. it is shown that the magnetic flux density of the disc-type MR fluid damper in the working areas can significantly change with the applied current in the coil; and that the dynamic behavior of the disc-type MR fluid damper can be varied by the application of an external magnetic field produced by a low voltage electromagnetic coil. The disc-type MR fluid damper can significantly change the dynamic characteristics of a rotor system, provided that the location of the disk-type MR fluid damper is carefully chosen. The disc-type MR fluid damper is a new actuator with good dynamic characteristics for rotating machinery.
