From concept to embodiment : challenge and strategy

Facing with the difficulty in information propagation and synthesizing from conceptual to embodiment design, this paper introduces a function-oriented, axiom based conceptual modeling scheme. Default logic reasoning is exploited for recognition and reconstitution of conceptual product geometric and topological information. The proposed product modeling system and reasoning approach testify a methodology of "structural variation design", which is verified in the implementation of a GPAL (Green Product All Life-cycle) CAD system. The GPAL system includes major enhancement modules of a mechanism layout sketching method based on fuzzy logic, a knowledge-based function-to-form mapping mechanism and conceptual form reconstitution paradigm based on default geometric reasoning. A mechanical hand design example shows a more than 20 times increase in design efficacy with these enhancement modules in the GPAL system on a general 3D CAD platform.

Towards ubiquitous city : concept, planning, and experiences in the Republic of Korea

Information and communication technologies (ICTs) had occupied their position on knowledge management and are now evolving towards the era of self-intelligence (Klosterman, 2001). In the 21st century ICTs for urban development and planning are imperative to improve the quality of life and place. This includes the management of traffic, waste, electricity, sewerage and water quality, monitoring fire and crime, conserving renewable resources, and coordinating urban policies and programs for urban planners, civil engineers, and government officers and administrators. The handling of tasks in the field of urban management often requires complex, interdisciplinary knowledge as well as profound technical information. Most of the information has been compiled during the last few years in the form of manuals, reports, databases, and programs. However frequently, the existence of these information and services are either not known or they are not readily available to the people who need them. To provide urban administrators and the public with comprehensive information and services, various ICTs are being developed. In early 1990s Mark Weiser (1993) proposed Ubiquitous Computing project at the Xerox Palo Alto Research Centre in the US. He provides a vision of a built environment which digital networks link individual residents not only to other people but also to goods and services whenever and wherever they need (Mitchell, 1999). Since then the Republic of Korea (ROK) has been continuously developed national strategies for knowledge based urban development (KBUD) through the agenda of Cyber Korea, E-Korea and U-Korea. Among abovementioned agendas particularly the U-Korea agenda aims the convergence of ICTs and urban space for a prosperous urban and economic development. U-Korea strategies create a series of U-cities based on ubiquitous computing and ICTs by a means of providing ubiquitous city (U-city) infrastructure and services in urban space. The goals of U-city development is not only boosting the national economy but also creating value in knowledge based communities. It provides opportunity for both the central and local governments collaborate to U-city project, optimize information utilization, and minimize regional disparities. This chapter introduces the Korean-led U-city concept, planning, design schemes and management policies and discusses the implications of U-city concept in planning for KBUD.

Adolescence: A useful concept for this millennium

‘Adolescence’ has become increasingly recognised as a nebulous concept. Previous conceptualisations of adolescence have adopted a ‘deficit’ view, regarding teenagers as ‘unfinished’ adults. The deficit view of adolescence is highly problematic in an era where adulthood itself is difficult to define. The terms ‘kidult’ or ‘adultescent’ have emerged to describe adult-age people whose interests and priorities match those of their teenage counterparts. Rather than relying on ‘lock-step’ models of physical, cognitive and social growth put forward by developmental psychology, adolescence can be more usefully defined by looking at the common experiences of people in their teenage years. Common experiences arise at an institutional level; for example, all adolescents are treated as the same by legal and education systems. The transition from primary to secondary schooling is a milestone for all children, exposing them to a new type of educational environment. Shared experiences also arise from generational factors. Today’s adolescents belong to the millennial generation, characterised by technological competence, global perspectives, high susceptibility to media influence, individualisation and rapid interactions. This generation focuses on teamwork, achievement, modesty and good conduct, and has great potential for significant collective accomplishments. These generational factors challenge educators to provide relevant learning experiences for today’s students. Many classrooms still utilise textbook-based pedagogy more suited to previous generations, resulting in disengagement among millennial students. Curriculum content must also be tailored to generational needs. The rapid pace of change, as well as the fluidity of identity created by dissolving geographical and vocational boundaries, mean that the millennial generation will need more than a fixed set of skills and knowledge to enter adulthood. Teachers must enable their students to think like ‘expert novices’, adept at assimilating new concepts in depth and prepared to engage in lifelong learning.

Adolescence : a useful concept for this millennium

This paper proposes adolescence as a useful concept rather than definitive. It explores the notion of adolescence and its relevance to contemporary society and schooling. We reflect on the purposes for the emergence of research into adolescence during the early 20th century, particularly the particular scientific and societal pressures that served to bring this field to prominence. Recent debate has started to problematise many of the early parameters used to define and provide bounds for understanding adolescents and adolescent experience and for the rationale for some notionally tailored educational contexts. This paper provides an overview of this debate and argues for a reconsideration of some of the basic tenets for definition. In particular we discuss the cultural construction of adolescence in the light of our new globalised society. A possibility for thinking about contemporary adolescents is by considering them in terms of generational characteristics. What makes a new generation? Typically, members of a generation share age, a set of experiences during formative years, and a set of social and economic conditions. The adolescents of today fall into the group known collectively as the ‘Y Generation’, the ‘D (digital) Generation’, Generation C (consumer) and the ‘Millennial’s’. Born after mid-1980, they are characterised as computer and internet competent, multi-taskers, with a global perspective. They respond best to visual language, and are heavily influenced by the media. We consider the generational traits and how this impacts on the teaching and learning.

The influences of conceptions of learning and learner self-concept on high school students' approaches to learning

This study investigated the mediating effect of learner selfconcept between conceptions of learning and students' approaches to learning using structural equation modelling. Data were collected using a modified version of Biggs' Learning Process Questionnaire, together with the recently developed 'What is Learning Survey' and 'Learner Self-Concept Scale'. A sample of 355 high school students participated in the study. Results indicate that learner self-concept does mediate between conceptions of meaning and approaches to learning. Students who adopted a deep approach liked learning new things and indirectly viewed learning as experiential, involving social interaction and directly viewed learning as personal development. Implications for teachers are discussed, with consideration given to appropriate classroom practice.

Elementary school students’ learner self-concept, academic self-concepts and approaches to learning

The present study investigated the relationships between academic selfconcepts, learner self-concept, and approaches to learning in elementary school students. A sample of 580 Australian Grade 6 and 7 school students with a mean age of 10.7 years participated in the study. Weak negative correlations between learner self-concepts and surface approaches to learning were identiŽ ed. In contrast, deep approaches for both boys and girls showed the highest positive correlations with school self-concept and learning self-concept. Only slight variations in these Ž gures were found between boys and girls.

Decolonising the concept of knowledge

Controlling the definition of what was essentially a subjugated culture, the colonisers reserve the power to distinguish authentic aspects of the living traditions of the colonised. If the colonised argue political demands by reference to their culture, the colonisers are quick to adjudicate what is genuine in such claims. (Fannon, 1967) Since colonial invasions, Australia’s Indigenous people have weathered rapid change. While the origins of Australia’s Indigenous peoples continues to be an archaeological interest for many, how Indigenous cultures have survived, transformed and retained a sense of ‘difference’ is fundamental to understanding the diversity of Aboriginal and Torres Strait Islander cultures within this continent as both contemporaneous and historical. It is important that teachers, students and researchers within Indigenous studies remind themselves that much of the literature on Aboriginal and Torres Strait Islanders can be ideologically traced back to the emergence of ‘knowledge’ about native peoples in the context of European imperialism and expansion from the fifteenth century. Care must therefore be taken in not conveying ‘scientific’ rational knowledge as perhaps the hidden agenda or notion of assumptions of European ‘superiority’ and non-European inferiority. The recognition by the High Court of Australia (1992) abandoned the legal myth of terra nullius which based the dispossession of Indigenous land on the basis of it being considered an empty land. It could also be argued that this decision recognised that distinct customs and traditions continue to exist within the social and cultural ‘knowledge’ of Indigenous peoples of Australia. General issues and concerns relating to research design, methodology and articulation within QUT are not just confined to this university and the research project presented as a case study but are important in dealing with how Aboriginal and Torres Strait Islander students and academics participate or are employed within the university. We feel that the design and methodology of research that either covertly or overtly focuses on Indigenous Australians can no longer presume that all research will naturally follow protocols that are culturally appropriate as this appropriateness is usually defined by the institution. By no means do we feel that research should be debilitated as a result of raising these issues, but that collaborative approaches within the ‘process’ of research will address Aboriginal and Torres Strait Islander people and communities as much as the intended outcomes of research itself.

The IMC concept meets political marketing : building brand relationships

There is a need to take a fresh look at the traditional application of the marketing concept to political marketing. As many businesses have learned, Integrated Marketing Communications (IMC) practices and principles will help them to build customer relationships and profitable brands. Political marketing must also change with the times and implement IMC practices toward building and nourishing brand relationships with voters and other important stakeholders. The nature of the contribution of this paper is the identification of a gap in the political marketing literature - the stagnation of political marketing at the 4P's marketing concept, and to play a role in the future development of political marketing. In recent developments, it is seen that there is a gradual movement away from this traditional marketing theory. There are a growing number of academics who have approached very closely to the IMC concept or aspects of it, but have not however embraced or have been reluctant to, the prospect of applying it to political marketing. IMC is a practical, logical and ultimately inevitable future for political marketing.

Self-concept and self-esteem in elementary school children

Confusion exists with regard to the empirical and substantive link between self-concept and self-esteem in elementary school children and their relationship to self-description, self-evaluation, and global beliefs and feelings about oneself as a person. This study reports the results of investigating the relationships between these self-constructs using 957 elementary school children in Grades 3 to 7. The evidence suggests that self-concept is comprised of both descriptive and evaluative beliefs that children hold about certain characteristics, whereas self-esteem can be viewed as the global feelings and beliefs that children have about themselves as people.

Self-concept or self-esteem

Confusion exists with regard to the substantive difference between self-concept and self-esteem. In an endeavour to cast some light on this confusion two studies were conducted with 1193 preadolescents using modified versions of two commonly used instruments designed to measure self-concept and self-esteem. Exploratory factor analysis indicated that both these instruments measure specific facets of the same construct, namely self.-concept. General or global self-concept proved to be a difficult construct to measure in preadolescent students.
