Knowledge and Values in Technology Education

This paper addresses two closely interrelated issues in Technology Education: knowledge and values. The starting point for the discussion is analysis of the nature of knowledge in technology education. Approaches for theorising knowledge will be analysed in this paper as well as problems associated with them. Three major types of problems are identified: problems with finding an appropriate approach for the analysis of technological knowledge; problems with a technocratic interpretation of technological knowledge for the purpose of its classification; and problems with establishing a consistent approach to distinguish common features of technological knowledge. A model that represents knowledge in technology education and the place of values in it is presented as a way of overcoming the problems specified. The claim is made that understanding of knowledge/values relationships can improve theoretical understanding of how technology education can be constructed.     

Agricultural credit problems and policies during the transition to a market economy in Central and Eastern Europe

This paper assesses the problems of financing Central and Eastern European agriculture during the present transitionary period and the role of government in this process. Initially the paper looks at why credit markets work imperfectly, even in well developed market economies, focusing on problems related to asymmetric information, adverse selection, moral hazard, credit rationing, optimal debt instrument choice and initial wealth. It shows why these and related problems may cause transaction costs to be so high that credit rationing and high interest rates are rational and efficient responses by lenders to the imperfect information problems of the agricultural sector. A series of specific, transition-related issues are then discussed which have worsened these problems within the Central and Eastern European agricultural sector. The potential roles of governments in solving these issues and actual observed interventions by Central and Eastern Europe governments through credit subsidies, loan guarantees and specialised agricultural lending institutions are analysed. Finally, the paper discusses how financial market innovations have solved some of the credit market problems and derives the implications for government policies.

Skills shortages and training: a forgotten dimension in new technology

Skills shortages and training problems are forgotten by many companies when they adopt new technology. 52 engineering firms in a 'traditional' industry in a single local labour market were interviewed to examine their attitudes to new technology and the skills and training implications of technology adoption. Skills and training issues were often forgotten or misjudged during the new technology appraisal process. It was these same areas which created most problems for many companies after adoption. Misjudgements concerning the level of labour force flexibility and training requirements for staff often created problems after the adoption of new technology. Skills shortages for adopting firms are most acute at the skilled level, this predominantly concerns the 'local labour market'. Most firms adopted a short term response to skills shortages. Relatively low utilisation of policy initiatives and 'formal' avenues of assistance prior to new technology adoption were also identified.

Maximizing production rate and workload smoothing in assembly lines using particle swarm optimization

Particle swarm optimization (PSO) one of the latest developed population heuristics has rarely been applied in production and operations management (POM) optimization problems. A possible reason for this absence is that, PSO was introduced as global optimizer over continuous spaces, while a large set of POM problems are of combinatorial nature with discrete decision variables. PSO evolves floating-point vectors (called particles) and thus, its application to POM problems whose solutions are usually presented by permutations of integers is not straightforward. This paper presents a novel method based on PSO for the simple assembly line balancing problem (SALBP), a well-known NP-hard POM problem. Two criteria are simultaneously considered for optimization: to maximize the production rate of the line (equivalently to minimize the cycle time), and to maximize the workload smoothing (i.e. to distribute the workload evenly as possible to the workstations of the assembly line). Emphasis is given on seeking a set of diverse Pareto optimal solutions for the bi-criteria SALBP. Extensive experiments carried out on multiple test-beds problems taken from the open literature are reported and discussed. Comparisons between the proposed PSO algorithm and two existing multi-objective population heuristics show a quite promising higher performance for the proposed approach.
