Selected AbstractsMultiple causality in developmental disorders: methodological implications from computational modellingDEVELOPMENTAL SCIENCE, Issue 5 2003Michael S.C. Thomas When developmental disorders are defined on the basis of behavioural impairments alone, there is a risk that individuals with different underlying cognitive deficits will be grouped together on the basis that they happen to share a certain impairment. This phenomenon is labelled multiple causality. In contrast, a developmental disorder generated by a single underlying cognitive deficit may nevertheless show variable patterns of impairments due to individual differences. Connectionist computational models of development are used to investigate whether there may be ways to distinguish disorder groups with a single underlying cause (homogeneous disorder groups) from disorder groups with multiple underlying causes (heterogeneous disorder groups) on the basis of behavioural measures alone. A heuristic is proposed to assess the underlying causal homogeneity of the disorder group based on the variability of different behavioural measures from the target domain. Heterogeneous disorder groups are likely to show smaller variability on the measure used to define the disorder than on subsequent behavioural measures, while homogeneous groups should show approximately equivalent variability. Homogeneous disorder groups should show reductions in the variability of behavioural measures over time, while heterogeneous groups may not. It is demonstrated how these predictions arise from computational assumptions, and their use is illustrated with reference to behavioural data on naming skills from two developmental disorder groups, Williams syndrome and children with Word Finding Difficulties. [source] Services of General Interest in EC Law: Matching Values to Regulatory Technique in the Public and Privatised SectorsEUROPEAN LAW JOURNAL, Issue 4 2000Colin Scott All the European Union Member States have long traditions of state activity in providing key services (such as the utilities, health and education) to their citizens and underpinning both such direct provision and provision of services by non-state actors with certain administrative or legal guarantees. In European Community doctrines they are referred to as ,services of general interest' within which is a narrower class of ,services of general economic interest'. The diverse national public service traditions have been challenged both by the requirements of the single market and by other pressures such as fiscal crisis and broader public sector reform. This article examines the means by which services to which special principles should be applied can be identified and focuses on the range of sometimes contradictory values denoted by the term ,services of general interest', examining the range of regime types (based on hierarchical, competition-based and community forms) by which those values might be pursued. The concluding section suggests that the matching of values to techniques should not be made according to the importance of the values to be pursued, but rather by reference to which techniques are likely to be effective given the configuration of interests and capacities and existing culture within the target domain. [source] REDUCTION WITHOUT REDUCTIONISM: A DEFENCE OF NAGEL ON CONNECTABILITYTHE PHILOSOPHICAL QUARTERLY, Issue 234 2009Colin Klein Unlike the overall framework of Ernest Nagel's work on reduction, his theory of intertheoretic connection still has life in it. It handles aptly cases where reduction requires complex representation of a target domain. Abandoning his formulation as too liberal was a mistake. Arguments that it is too liberal at best touch only Nagel's deductivist theory of explanation, not his condition of connectability. Taking this condition seriously gives a powerful view of reduction, but one which requires us to index explanatory power to sciences as they are formulated at particular times. While we may thereby reduce more than philosophers have supposed, we must abandon hope (as Nagel did) of saying anything useful about reductionism. [source] Impact of research investment on Cassava production technologies in India,AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 3 2009Tavva Srinivas The present study was an ex-post assessment done to validate past funding on cassava research, based on economic surplus approach. Though cassava was introduced as a food crop in Kerala, India from Brazil, it has changed its status to commercial crop at present in Tamil Nadu and Andhra Pradesh states. This was made possible due to intensive research and development efforts of different R&D organizations. Cassava technologies developed enabled in sustaining the crop in the country with the world's highest productivity. All the cassava production technologies considered in the study resulted in an economic surplus of Rs.3585.87 million in the target domain covering Kerala, Tamil Nadu and Andhra Pradesh. Consumers and producers benefited to the tune of Rs.2090.64 million and Rs.1495.23 million respectively. Net present value of economic gains was estimated to be Rs.3548.76 million. Present value of research investment on cassava production technologies was Rs.37.11 million resulting in benefit cost ratio of 96.63:1 with a high internal rate of return of 104 per cent. Thus the study indicated that the research investments incurred on cassava production technologies development was highly economical and provided evidence to the policy makers that supporting the research investment on underground, under exploited tropical root crops like cassava is an economically viable proposition. [source] Trope Control: The Costs and Benefits of Metaphor Unreliability in the Description of Empirical Phenomena,BRITISH JOURNAL OF MANAGEMENT, Issue 2 2004John Ramsay The process of communicating and interpreting the meaning of metaphors in business writing is deeply unreliable. This stems from the structure of metaphors in which some of the characteristics of a source domain are transferred to a target domain. The precise selection of characteristics is made by the reader rather than the author of the metaphor, thus creating uncertainty of meaning. Although there are some benefits stemming from the inherent ambiguity of metaphor, the unreliability of the trope not only makes it impossible to choose between competing metaphors, but may distort our view of reality and thus lead to poor management decision-making. Moreover, the unreliability of the interpretation process is so pronounced that some authors have attempted to reject the use of metaphor entirely. However, this paper argues that although it is impossible to avoid employing metaphor, contrary to the conventional wisdom in this subject area, it is possible to improve meaning reliability. Drawing on linguistic theory to explain the recommendations, and illustrative examples from business literature and practice, the papers offers several recommendations for so doing that may be applied throughout the Business and Management field.
