This paper reports a study of science graduates who are employed in positions outside their discipline specialisation. The research was designed to uncover the reasons for them choosing to study science at university, the competencies they utilise in their work and their lives, and how these relate to their undergraduate education in science. The study is seen as important in that already about one-half of science graduates are in such positions and it is argued that there is a need in scientific and technologically based societies to have a greater representation of such people in decision-making positions in government and industry. The directions for the science degree that can be drawn from the data gathered are congruent with those arising from other relevant studies. That is, attention should be paid to widely used skills, such as communication and problem-solving, and to developing an understanding of science within its social and ethical context. An argument is mounted for considering the way the science degree is presented to potential students and to the general public.

This study examined the financial costs of multiple sclerosis (MS) and the impact of financial strain on the subjective quality of life of people with MS and their families. Due to the lack of research in this area, a qualitative research design was employed. Interviews were conducted with 16 health professionals, 26 people with MS, and 11 family members of people who had MS. Adjusting to actual or threatened loss of income caused financial stress. These financial struggles led to a lower quality of life among respondents. Problem solving, coping, and positive reappraisal helped people to adjust to financial changes. Professionals focused on increased funding for services, whereas people with MS focused on improved income support. These findings highlight the need for professionals to consider the financial strain associated with this disease and the impact of this strain on the quality of life of individuals with MS and their families.

The new translations of Freud into English highlight the question as to the nature of Freud's quest and achievement. They show a livelier Freud than the Strachey translations (Freud, 1953-1974), who used everyday language in his work instead of trying to establish a new technical vocabulary for an esoteric new discipline. However, with the new Penguin editions thus far, fresh Freud is no longer lost in translation. The Standard Edition was created importantly to create an authoritative international trademark and was made more natural "scientific" in appearance. The fresh translations show a Freud in tune with Karl Popper's (1976) approach in his later work that viewed science as essentially problem solving. The example of "Mourning and Melancholia" (Freud, 1917/ 1964, 1917/1981, 1917/2005) is discussed as an exercise in exploration, conjectures, criticism, construct formation, and problem solving. Translation issues are discussed. Instead of being a particular trade mark, the very fact of there being new and different translations opens Freud's works to further questioning about their meanings and intents in the marketplace of ideas and practices

Previous research by the authors has shown that Confucian Heritage Students participating in online problem solving discussions show a high degree of message postings that are related to the organization of the course of study, rather than to its contents and intellectual challenges. The authors argue that this is consistent with the more broadly based research outcomes relating to the achieving strategy that is quite typically exhibited among CHC students. This interview based study explores the perceptions of CHC students as they engage with collaborative learning online, and shows that the concerns relate to matters to do with assessment, with the reliability and timeliness of group member inputs, and the possibilities of plagiarism.

Many teachers are now incorporating a broader range of strategies into their teaching, including problem solving, investigations and open-ended questions. Among other things, such teaching requires teachers to talk less but to make more decisions. The acknowledgment of this complexity and the centrality of active decision making have implications for teacher education and teacher development, and for the strategies and resources used.

The relationship between normative patterns of social interaction and children's mathematical thinking was investigated in 5 classes (4 reform and 1 conventional) of 7- to 8-year-olds. In earlier studies, lessons from these classes had been analyzed for the nature of interaction broadly defined; the results indicated the existence of 4 types of classroom cultures (conventional textbook, conventional problem solving, strategy reporting, and inquiry/argument). In the current study, 42 lessons from this data resource were analyzed for children's mathematical thinking as verbalized in class discussions and for interaction patterns. These analyses were then combined to explore the relationship between interaction types and  expressed mathematical thinking. The results suggest that increased complexity in children's expressed mathematical thinking was closely related to the types of interaction patterns that differentiated class discussions among the 4 classroom cultures.

Care giving situations contain several features that offer opportunities for expanding the way that collaborative cognition is conceptualised and explored. These features are the presence of several possible contributors, more than one kind of change in participation, distinctions drawn among parts of a task, and differences in understanding based on interests. All represent departures from the traditional focus on dyads, tasks that emphasise one kind of change only, single problems, and differences in competence or expertise. All are also features likely to be found in everyday problem solving. Study 1 focuses on family contributions, based on reports by care givers about their current situation and their preferences for the involvement of other family members. Study 2 presents a standard family scenario and focuses on the views held by care givers, older adults, and community nurses about the reasonableness of various changes in participation. Results are discussed in terms of the ways situations such as care giving can help build a richer picture of collaborative cognition, one that is applicable to a variety of tasks and to all parts of the life span.

This Report summarises the outcomes of the phases of the Professional
Development for the Future Project and presents the implications of this research for professional development of staff in Vocational Education and Training (VET), as they become knowledge workers.

These shifts are occurring within the knowledge era. Distinguishing features of this era are summarised into four broad areas:
- the importance and value placed on knowledge in organisations
- the time span of discretion
- the complexity of relationships, and
- the ubiquitous nature of information and communication technology.

It is within this context that work is currently performed, and understanding this context provides the foundation for considering new capabilities required in the knowledge era.
Key capabilities required of knowledge workers to work effectively in the
knowledge era were drawn together from an analysis of the theoretical literature and the results of interviews with knowledge workers. The core capabilities identified include:
- adaptive problem solving – becoming designers as well as problem -
solvers
- rapid knowledge gathering and sharing with others
- discriminating between relevant and irrelevant information, and
- understanding and working effectively with the organisation’s culture.

Knowledge era characteristics and knowledge worker capabilities have been mapped to each other illustrating conceptual linkages between these two areas.

Professional development themes drawn from interviews with knowledge
workers are presented. While global trends in knowledge work have been well documented, the impact of these trends on the capabilities of workers, and the ways in which knowledge workers develop these capabilities is less well understood. Their learning methods challenge our current thinking in relation to the ways in which workers acquire skills and knowledge. Some of the professional development methods include seeking exposure to new ideas from a wide variety of sources, embracing intense learning opportunities, and using relationships to increase knowledge.

‘Thought pieces’ (see p17 ff) commissioned for this Project, as well as
subsequent interviews with the authors, provided further insights into the
professional development of knowledge workers. The implications of these insights are an extension of earlier themes and emphasise:
- the emergent nature of knowledge work
- the importance of relationships that facilitate knowledge sharing
- coherent conversations and dialogue
- collaborative work and generosity.

A key insight is the shift from thinking about knowledge work in terms of
borrowed knowledge to an emphasis on generated knowledge within a context.

Data from focus groups of the Project provide further insights for knowledge worker professional development. These augment the perspectives of the earlier data analysis but also add greater emphasis to:
- the clear and direct relationship between professional development and
work and career aspirations of knowledge workers,
- the relationship of professional development to the organisational
mission, and
- the issues of managing and leading knowledge workers and their
development.

As part of this analysis the defining features of organisational life in VET were reviewed in relation to effective professional development of knowledge workers.

The final section of the Report revisits the core dimensions of the Project.
Concise commentaries on working and learning in the knowledge era,
professional development in the knowledge era, and leadership and
management in the knowledge era are presented.

The Report concludes with a discussion of the enablers of professional
development for knowledge workers in VET. This discussion is introduced by a re-statement of the VET sector’s positioning in the knowledge era and the consequences of this for VET managers an d staff in terms of complexity, uncertainty and diminished prospects for accurate predictiveness. The enablers comprised:
- integration of information technology into socio -technical systems
- greater understanding of the organisation from within
- connecting staff to the organisation’s fundamental identity
- connecting to the work and career trajectories of workers
- establishing work structures which integrate the use of professional
development resources with knowledge work
- providing workers with the autonomy to design their own professional
development activities
- building professional development into the iterative nature of knowledge
work, and
- creating organisational contexts that value intuitive thinking and working.

Professional development needs to be thou ght of in a much broader context in the knowledge era. What each VET staff member knows and shares will become increasingly central to their work, and in that sense all VET workers require capabilities for knowledge work. This report accurately describes t he VET context, the capabilities required, and the organisational enablers that will promote ‘knowing’ and thus embed a new style of professional development within VET.

For over a decade, the graphic calculator has been promoted not only as a computational tool, but also as a thinking tool - for example, as an aid to enhance conceptual understanding, as a problem-solving tool and as a means of enabling students to engage in meaningful investigations. However, research studies focusing on these aspects have shown mixed results and have mostly focused on graphs and functions.

This paper reports on one aspect of a case study in a year 10 mathematics classroom - the role of the graphic calculator as a thinking tool. Data from observations of nine statistics lessons and interviews with the teacher and five students, are analysed from three perspective's: the teacher's intentions with respect to the use of the graphic calculator as a tool to promote conceptual understanding as opposed to procedural competence; the opportunities afforded during the lessons for student investigation; and students' views of how the graphic calculator enhanced conceptual understanding.

The results provide insights into ways in which students perceive the graphic calculator as promoting conceptual understanding, as well as some of the difficulties encountered in practice in a classroom where the teacher clearly intends to use the graphic calculator as a thinking tool.

Technology education provides children with opportunities to be creative as they engage in problem solving and make products that address human needs. When thinking creatively, children generate new ideas through remote associations and brainstorming and this type of thinking is enhanced when attention is allowed to wander in a relaxed and uncompetitive environment. Research shows that the two mental states (generative and nongenerative/analytical) cannot exist simultaneously (Howard-Jones 2002). It follows that at some point in the technological process a child’s generative mental state needs to give way to a nongenerative, analytical state so that the child can focus on analysing information. This research project aims to investigate the impact of analytical thinking on creativity in the context of technology education in young children.

Problem solving is often seen as being the core of mathematics. While there are many examples of teaching for and about problem solving, there are relatively few examples of teaching mathematical content through problem solving. This paper uses data from three, apparently quite different, mathematics lessons from Australia and Japan to explore different ways in which mathematics can be taught successfully through problem solving and to analyse some of the characteristics of such lessons. It also attempts to identify some of the supports and constraints for adopting a problem solving approach to the teaching of mathematics that exist in the quite different contexts of Japan and Australia.

Creativity is important in the discovery and analysis of user and business requirements to achieve innovative uses of information and communication technologies. This paper builds a theoretical framework for understanding creativity in requirements engineering. The framework provides a systematic means of understanding creativity in requirements engineering and comprises five elements (product, process, domain, people and socio-organisational context). The framework provides researchers with a sound basis for exploring how the five elements of creativity can be incorporated within RE methods and techniques to support creative requirements engineering. It provides practitioners with a systematic means of creating environments that nurture and develop creative people, cognitive and collaborative processes and products.

Computers of a non-dedicated cluster are often idle (users attend meetings, have lunch or coffee breaks) or lightly loaded (users carry out simple computations to support problem solving activities). These underutilised computers can be employed to execute parallel applications. Thus, these computers can be shared by parallel and sequential applications, which could lead to the improvement of their execution performance. However, there is a lack of experimental study showing the applications’ performance and the system utilization of executing parallel and sequential applications concurrently and concurrent execution of multiple parallel applications on a non-dedicated cluster. Here we present the result of an experimental study into load balancing based scheduling of mixtures of NAS Parallel Benchmarks and BYTE sequential applications on a very low cost non-dedicated cluster. This study showed that the proposed sharing provided performance boost as compared to the execution of the parallel load in isolation on a reduced number of computers and better cluster utilization. The results of this research were used not only to validate other researchers’ result generated by simulation but also to support our research mission of widening the use of non-dedicated clusters. Our promising results obtained could promote further research studies to convince universities, business and industry, which require a large amount of computing resources, to run parallel applications on their already owned non-dedicated clusters.
