In education, there is much rhetoric about a school's capacity to prepare learners for 'the future'. For example, there have been 'Schools of the future', 'Lighthouse schools of the future' and many claims from schools around the world that their roles encompass 'educating students for the future' and developing 'citizens of the future'. However, as 'futures educators', the questions must be asked: 'whose future?' and 'what future?'. Considering texts which promote this educational premise require tools and philosophical understandings, in order to deconstruct and articulate the future for which we prepare our young. This paper describes the way in which foresight literacy can be developed through engagement with explicit futures education tools and concepts. It highlights a number of futures texts indiscriminately presented within culture and society, and exposes some of the ways in which foresight (futures) understandings can be achieved. This reading, writing and articulation of a multiplicity of futures is referred to as foresight literacy. This paper does not address the 'future of literacy', but rather the way in which futures education equips students to engage with texts assuming, and describing a future.

In New Times (Hall, 1996), there has been much rhetoric about school’s role in equipping students for the future. Futures education, or futures pedagogy, provides an interdisciplinary approach in which alternative futures may be explored, designed and articulated. Enactivism, as a theory of learning, affirms my contention that it is not enough to talk about the future. Rather, I propose that education must act as an agent of change, in equipping teachers and students alike, to imagine, critique and create possible, preferable and probable futures. This paper, then, explores the co-emergence (Manturana & Varela, 1992) of an explicit futures dimension, and teaching and learning drawing upon case studies of practice in schools.

In the post-modern world, it has been said that there is now greater uncertainty in life than in any previous period, simply because so much has changed as a result of the speed of technological change.

From the educational view point, Futures education is a necessity as times continue to change, in regards to both the sustainability of the person and that of the environment. It is true that uncertainty will always remain an aspect of thinking about the future, however in order to make what is ahead more accessible to everyone, educators have a duty of care to their students to facilitate or educate in regards to tools, concepts and understandings which will help students to become world shapers, and shapers of their own personal futures. This must occur as part of ongoing educator training.

The use of willingness to pay to value the benefits of health care is increasing. Much of this work assumes that health preferences are well formed or complete and readily revealed if the right question is asked in the right way. We examined this assumption, seeking evidence in a mixed-methods study that explored the meaning and implications of vague responses to a payment-scale based willingness to pay exercise.

One-half of the sample said that their vagueness meant that their maximum willingness to pay was actually greater than the amount that they had previously said it was. Thirty percent agreed that they would probably pay £10 more than a sum that they had previously said they would most definitely not pay, if they found this to be the cost of the vaccine. Interview data supported the view that the payment scale had failed to elicit the maximum willingness to pay and that some participants used the information on cost to help clarify their values, in contrast to the theory underpinning willingness to pay. The results suggest a need to consider values-clarification in health economic evaluations. Copyright © 2002 John Wiley & Sons, Ltd.

Research indicates that the environment has had a definite impact on consumer behaviour whereby suggesting to target consumers according to their environmental beliefs. This study investigated the consumers' green purchase behaviour using price and quality attributes as contributors to the formation of purchase intention. It attempts to construct a model that may facilitate the better understanding of green consumers' market segments through the use of an intelligent soft computing model. The model is designed to incorporate knowledge, beliefs, demographic profiles and situational variables. This potentially provides a more direct method for companies to gauge consumers' intention to purchase green products. The results showed strong preference for companies to place higher priority on reducing pollution than on increasing profitability. It highlighted different clusters that demonstrate various levels of the strength of intention to purchase and market segment profiles.

This study analyses the dynamic causality of four macroeconomic variables on house prices. The four macroeconomic variables have interrelationships with house prices in certain lagged terms, but these relationships are not always the same as the notions put forward in prior research. The relationships are detected to be unstable in the three observation periods. The instability of these relationships would cause difficulty in predicting house prices in the market, especially for policy makers and market participants.

The ripple effect of house prices within metropolitan areas has recently been recognised by researchers. However, it is very difficult to formulate and measure this effect using conventional house price theories particularly in consideration of the spatial locations of cities. Based on econometrics principles of the cointegration test and the error correction model, this research develops an innovative approach to quantitatively examine the diffusion patterns of house prices in mega-cities of a country. Taking Australia's eight capital cities as an example, the proposed approach is validated in terms of an empirical study. The results show that a 1-1-2-4 diffusion pattern exists within these cities. Sydney is on the top tier with Melbourne in the second; Perth and Adelaide are in the third level and the other four cities lie on the bottom. This research may be applied to predict the regional housing market behavior in a country.

The goal of this paper is to examine the relationship between real GDP and oil prices using time series data for the period 1970–2005. Our main finding is that an increase in oil has a positive, albeit inelastic, impact on real GDP, inconsistent with the bulk of the literature. We argue that this is not a surprising result for the Fiji Islands. Our central argument focuses on two aspects of the Fijian economy: (1) the fact that actual output in Fiji has been around 50 per cent less than potential output; thus, Fiji's actual output has not reached a threshold level at which oil prices can negatively impact output; and (2) a rise in oil prices filters through to value added, which in turn is reflected in a larger actual output.

This paper discusses in its entirety, the CIO (Chief Information Officer) position in the public sector. Governments are increasingly adopting Information Technology for internal processes and for the delivery of service to their citizens. It includes literature on CIO roles and responsibilities which is heavily based on the private sector, due to the recognition of the role in this sector over twenty years. The position is just evolving in the public sector, and due to the context in which the public sector operates there are some similarities as well as vast differences. An evaluation of existing CIO models and theories form the basis for research on CIO roles, responsibilities and future within the public sector.

The role of commodity prices and subsidies on the adoption of soil conservation has been widely debated yet is poorly understood. One reason for this is the complex nature of the relationship between soil loss and yield damage. This paper examines the effects of price and subsidy policy on adoption of soil conservation measures in tea lands in Sri Lanka. The soil conservation technologies considered are lateral drains, stone terraces and Sloping Agricultural Land Technique (SALT). The study uses a non-linear yield damage function to estimate tea yield loss due to soil erosion. The yield function is then used in conjunction with a simple analytical model to examine the effects of changes in price and subsidies
on the incentives to adopt various soil conservation technologies. When there is a yield increment with soil conservation, increases in both prices and subsidies are found to make soil conservation economically attractive.

This paper examines dynamic interdependence, volatility transmission, and market integration across selected stock markets during the Asian financial crisis periods 1997 and 1998. Using a vector autoregressive–exponential generalized autoregressive conditional heteroskedasticity (VAR-EGARCH) model, it is found that reciprocal volatility transmission existed between Hong Kong and Korea, and unidirectional volatility transmission from Korea to Thailand. This suggests that Hong Kong played a significant role in volatility transmission to the other Asian markets. The data also indicate market integration in that each market reacted to both local news and news originating in the other markets, particularly adverse news.
