The need to change pedagogies in science and technology subjects: a European perspective

This paper evolves out of a consultancy that was carried out with the European Commission over a two year period between 2001 and 2003. A working group, set within the European Commission and comprising representatives from 15 member states, as well as associated and accession countries, stakeholders and social partners involved in maths, science and technology education, was formed. Its remit was to identify good practice in maths, science and technology education across Europe and to make recommendations for policy makers in the area. One important theme which emerged during the analysis of good practice was the need to develop the type of pedagogies which would encourage the active involvement of pupils in authentic and meaningful learning experiences within these subject domains. A series of questions relating specifically to this area was therefore incorporated into the second phase of the investigation and sent out to all participating countries. Qualitative analysis of these questionnaires was carried out. Using the results of these analyses, along with information from discussions, this paper considers the situation in Europe in respect of the introduction of what are essentially social constructivist pedagogies in the field of technology and science education. It explores some of the attempts which have been made to implement such pedagogies and more importantly the barriers to their introduction which have been identified in most countries across Europe. A consideration of research literature in the field is then used to promote the argument that teacher beliefs or theories are a crucial factor in preventing change. The role of these theories in presenting barriers to change are discussed and the implications for both policy makers and for initial teacher education are analysed.     

Where Are They Now? Tracking the Ph.D. Class of 1997

We report early career outcomes of economics Ph.D.s by tracking the U.S. class of 1996-1997. We examine employment outcomes, work activities, salaries, and graduates' attitudes toward their jobs. By 2003, all of the respondents were employed, although almost half changed employers during the six years. Salaries of the cohort increased at an average annual rate of 8.2% from 1997 through 2003. Academic-year salaries rose about 5.7% per year, whereas private sector salaries skyrocketed at 15% per year. Finally, the median salaries of first-year full-time permanent 9- to 10-month academic economists hired in 2002-2003 actually exceed the median 2003 salaries of their counterparts initially hired in 1997-1998. Some of this apparent salary inversion reflects a different mix of employers and departments between the two cohorts, with the younger group securing relatively more jobs at higher-paying institutions.     

Land change in the Brazilian Savanna (Cerrado), 1986–2002: Comparative analysis and implications for land-use policy

The Brazilian Cerrado, a biodiverse savanna ecoregion covering 1.8 million km² south and east of the Amazon rainforest, is in rapid decline because of the expansion of modern agriculture. Previous studies of Cerrado land-use and land-cover (LULC) change imply spatial homogeneity, report widely varying rates of land conversion, use ambiguous LULC categories, and generally do not attempt to validate results. This study addresses this gap in the literature by analyzing moderate-resolution, multi-spectral satellite remote sensing data from 1986 to 2002 in two regions with identical underlying drivers. Unsupervised classification by the ISODATA algorithm indicates that Cerrado was converted to agro-pastoral land covers in 31% (3646 km²) of the study region in western Bahia and 24% (3011 km²) of the eastern Mato Grosso study region, while nearly 40% (4688 km² and 5217 km², respectively) of each study region remained unchanged. Although aggregate land change is similar, large and contiguous fragments persist in western Bahia, while smaller fragments remain in eastern Mato Grosso. These findings are considered in the current context of Cerrado land-use policy, which is dominated by the conservation set-aside and command-control policy models. The spatial characteristics of Cerrado remnants create considerable obstacles to implement the models; an alternative approach, informed by countryside biogeography, may encourage collaboration between state officials and farmer-landowners toward conservation land-use policies.     

Do Better‐Governed Australian Firms Make More Informative Disclosures?

Abstract:   We investigate whether and if so, how, corporate governance 'quality' ¹ is related to the information flows from a company and how the share market and its agents respond. Specifically, we study links between the 'quality' of a firm's corporate governance (CGQ) and the informativeness of its disclosures. We employ six indicators of informativeness. They include document counts, properties of analysts' forecasts and a 'timeliness' metric, in the spirit of Ball and Brown (1968) , that reflects the average speed of price discovery throughout the year. Our results suggest the answer to our question is 'Yes': better‐governed firms do make more informative disclosures.     

Risk-based pricing of interest rates for consumer loans

By focusing on observable default risk's role in loan terms and the subsequent consequences for household behavior, this paper shows that lenders increasingly used risk-based pricing of interest rates in consumer loan markets during the mid-1990s. It tests three resulting predictions: First, the premium paid per unit of risk should have increased over this period. Second, debt levels should have reacted accordingly. Third, fewer high-risk households should have been denied credit, further contributing to the interest rate spread between the highest- and lowest-risk borrowers.For people obtaining loans, the premium paid per unit of risk did indeed become significantly larger after the mid-1990s. For example, for a 0.01 increase in the probability of bankruptcy, the corresponding interest-rate increase tripled for first mortgages, doubled for automobile loans and rose nearly six-fold for second mortgages. Additionally, changes in borrowing levels and debt access reflected these new pricing practices, particularly for secured debt. Borrowing increased most for the low-risk households who saw their relative borrowing costs fall. Furthermore, while very high-risk households gained expanded access to credit, the increases in their risk premiums implied that their borrowing as a whole either rose less or, sometimes, fell.     

The organizing vision of application service provision: a process-oriented analysis

The processes by which information systems (IS) innovations become institutionalized are the subjects of much debate within the field of organization theory. Yet few empirical studies exist which examine how IS innovations come to be adopted and diffused across organizations. This paper draws from neo-institutional theory by extending the work of Swanson and Ramiller, using their concept of the organizing vision as a lens for observing and analysing an emerging information systems innovation targeted at small and medium enterprises (SMEs), which came to be known as application services provisioning (ASP). We observe that over time, the initial euphoria and ‘hype’ which surrounded the organizing vision of ASP was replaced by scepticism and distrust, as powerful institutional interests in the form of leading technology firms, industry analysts and IT consultancies were ultimately unsuccessful in their attempts to disseminate ASP throughout the wider business and not-for profit IS user communities. The lessons from this research suggest that a processes-oriented analysis of how organizing visions are interpreted, legitimised and mobilized is critical for understanding and explaining how underdevelopment of an organizing vision at an early stage, may inhibit its later adoption and institutionalization.     

The strategic management of a large scale IT project in the financial services sector

This article explores theoretical and empirical work on IT strategy formulation. While the managerialist focus upon a structured rational text-book model is common in the literature, it is not supported by empirical research on IT projects in the financial services sector.     

The Usefulness of Experimental Auctions in Determining Consumers' Willingness-to-Pay for Quality-Differentiated Products

The validity and effectiveness of using experimental auctions to elicit consumers' willingness-to-pay for closely related, quality-differentiated products is examined. The effect of panelists' demographics on bid values and auction winners, and the impact of experimental procedures on auction prices are analyzed. Demographic variables are poor predictors of bids and auction winners. Experimental procedures such as panel size and initial endowment influence market price level. Relative bid differences for paired samples are primarily influenced by relative differences in taste panel ratings. Relative willingness-to-pay values elicited through experimental auctions appear valid, while actual willingness-to-pay values are influenced by experimental design.
