Combination of decisions from a multiple neural network classifier system

In this paper, a study of the effectiveness of a multiple classifier system (MCS) in a medical diagnostic task is described. A hybrid network, based on the integration of a fuzzy ARTMAP and the probabilistic neural network, is employed as the basis of the MCS. Outputs from multiple networks are combined using some decision combination method to reach a final prediction. By using a real medical database, a set of experiments has been conducted to evaluate the performance of the MSC with different network configurations. The experimental results reveal the potential of the MCS as a useful decision support tool in the medical field.

Thabo Meli revisited : the pernicious effects of results-driven decisions

Despite the hackneyed expression that ‘judges should interpret the law and not make it’, the fact remains that there is some scope within the separation of powers doctrine for the courts to develop the common law incrementally. To this extent, the courts can effectively legislate, but only to this limited extent if they are to respect the separation of powers doctrine. On occasion, however, the courts have usurped the power entrusted to Parliament, and particularly so in instances where a strict application of the existing law would lead to results that offend their personal notions of what is fair and just. When this occurs, the natural consequence is that lawyers, academics and the public in general lose respect for both the judges involved as well as the adversarial system of criminal justice. In order to illustrate this point, attention will focus on the case of Thabo Meli v United Kingdom in which the Privy Council, mistakenly believing that it could not reach its desired outcome through a strict application of the common law rule of temporal coincidence, emasculated the rule beyond recognition in order to convict the accused. Moreover, the discussion to follow will demonstrate that not only was the court wrong in its belief that the case involved the doctrine of temporal coincidence, but the same result would have been achieved had the Council correctly identified the issue as one of legal causation and correctly applied the principles relating thereto.

Making decisions about fertility : three facts GPs need to communicate to women

Background Average annual fertility rates in industrialised countries have been below two children per woman for the past 3 decades. The reasons behind women’s childbearing behaviour are complex. However, a lack of awareness regarding the consequences of delayed childbearing and the inability of reproductive technologies to overcome the ‘biological clock’ may be contributory factors.

Objective A narrative review guided by the research question: What do women need to know about the consequences of delayed childbearing in order to make informed decisions about their fertility?

Discussion There are three facts that women need to know in order to make informed decisions around their fertility: Some women want to have more children than they are able to have because they postpone childbearing; there can be medical consequences to delaying childbearing and; some women’s ideas about their fertility don’t match the ‘the scientific facts’. General practitioners are well placed to play a strategic role in the provision of timely, relevant information to help women make informed decisions about their fertility. Further research is needed to identify the most appropriate ways for GPs to communicate this information.

Workers, a neglected voice in environmental decisions

The European Aarhus Convention is the only public law convention devoted to public participation in environmental matters. The Convention has application broadly to Australia as many of the Convention’s provisions are reflected in Australian environmental law. The Convention has an ambitious aim being, to engage civil society in effective public participation at all levels of environmental decision-making. Trade unions and workers as members of civil society are granted rights under the Aarhus Convention to participate in environmental decisions. However in spite of this, the trade union movement has largely ignored the Convention. This article examines the potential rights which the Convention grants to trade unions and workers and explores the broader debate regarding the involvement of unions in environmental matters.

Shared beliefs, expectations and surprises: adaptation decisions of village tank farmers in Sri Lanka

This study examined adaptation decisions of village tank farmers in Sri Lanka, focusing on how commonly held beliefs on local rainfall influence their adaptation choices. Findings suggest that farmers’ have shared beliefs consistent with local pattern of rainfall variability that help to explain short-, medium- and long-term decisions of adaptation.

Factors influencing students’ decisions about post-year 10 education

This paper reports pilot data from an instrument devised as part of a large ARC funded project that aims, among other things, to investigate factors that influence the decisions of students in rural and/or disadvantaged areas to continue their schooling beyond Year 10. One section of the pilot student questionnaire comprised 42 items designed to reflect dimensions believed to influence these decisions. Participants responded on 5-point Likert scales indicating the extent of their agreement from Strongly Disagree to Strongly Agree with each of the items. We were interested in the extent to which the data supported the theoretical structure that underpinned the structure of the questionnaire and in testing the appropriateness of the language used. The large scale data collection will survey students from Years 5 to 11 with as few adaptations for differences in literacy levels across that range as possible. To this end, the pilot questionnaire was administered to Year 5 (n = 44) and Year 9/10 students (n = 50) with identical wording for both grade levels. A factor analysis of the complete data set (n = 94) provided initial evidence that being happy at school; having family support to continue with education, and appropriate curriculum options and extra-curricular activities, perceiving oneself as a high achiever both in general and in relation to mathematics, having teacher and peer support to continue, being positive about English, planning to be an apprentice, and having a job type in mind are dimensions worthy of further exploration in the larger study.
