The impact of contractor selection method on transaction costs: a review

The basic premise of transaction-cost theory is that the decision to outsource, rather than to undertake work in-house, is determined by the relative costs incurred in each of these forms of economic organization. In construction the "make or buy" decision invariably leads to a contract. Reducing the costs of entering into a contractual relationship (transaction costs) raises the value of production and is therefore desirable. Commonly applied methods of contractor selection may not minimise the costs of contracting. Research evidence suggests that although competitive tendering typically results in the lowest bidder winning the contract this may not represent the lowest project cost after completion. Multi-parameter and quantitative models for contractor selection have been developed to identify the best (or least risky) among bidders. A major area in which research is still needed is in investigating the impact of different methods of contractor selection on the costs of entering into a contract and the decision to outsource

An Agent-based approach to modelling integrated product teams undertaking a design activity.

The interactions between individual designers, within integrated product teams, and the nature of design tasks, all have a significant impact upon how well a design task can be performed, and hence the quality of the resultant product and the time in which it can be delivered. In this paper we describe an ongoing research project which aims to model integrated product teams through the use of multi-agent systems. We first describe the background and rationale for our work, and then present our initial computational model and results from the simulation of an integrated product team. The paper concludes with a discussion of how the model will evolve to improve the accuracy of the simulation

The Blind Man

I know you as you walk among my rooms,Your head turned thus, your shoulders moving so, Your hands made busy with the sound of brooms, The many little tasks that women know. Dear brilliant lady, as you come and go, Is light lent to my days. In you I find A roof against the rain-let winter blow! Look on me, love, with kindness; for my mind, My heart, my searching hands that clasp you-are not blind

An investigation into attitudes relating to sex and sexuality of people who have a learning disability

The area of sexuality for people with learning disability is a much neglected area of research. It is possible that this may be influenced by the attitudes that professionals have towards the sexuality of the people they work with. In order to discuss this issue the literature review in chapter one provides an overview of the studies carried out over the past twenty years concerning staff attitudes towards the sexuality of people with learning disabilities. This discussion will be set within the context of the principles outlined in the Government White Paper. Current research examining the behaviour of men who have a learning disability and sexually offend has been completed without the use of control groups, thus making it difficult to assess whether there are any differences between men who sexually offend and those who do not. Although the current literature identifies some of the characteristics that may contribute towards the risk of offending, it does not present any information regarding models of offending for people who have a learning disability. The research in Chapter two explores the attitudes of men, both offenders and non-offenders with learning disabilities, towards sex and sexuality their experiences. Semi-structured interviews were carried out and analysed using grounded theory methodology and theoretical models developed. Methodological limitations, clinical implications and future research were also considered. Chapter three demonstrates some of the researcher's reflections on research with sex offenders. These include the methodological choice of grounded theory and its' appropriateness when used with people who have a learning disability, the impact of the researcher's gender on the interview process and some of the issues that being pregnant during the interviews posed. Finally, supervision and its' significance in terms of the subjectivity and bias of data interpretation is discussed
