    Tri-Institutional Library Support: A Lesson in Forced Collaboration

    This paper discusses the trials and tribulations of three separate institutional libraries supporting one new graduate-level academic program. In January 2002, a new distance graduate program in Applied Psychology began with technical, administrative, and academic support provided by three separate institutions. While one institution was initially charged with providing the bulk of library services, in reality, libraries at all three have contributed one service or another. The lead library provides remote database access and document delivery, and initially provided electronic reserves. After the first semester and several glitches, electronic reserves were moved to institutional library #2, which was also hosting the course management system. In the fall of 2002, institutional library #3 began to contribute with an information literacy module that has been incorporated into the orientation for all new students

    Memory and self-induced shocks in an evolutionary population competing for limited resources

    Full text link
    We present a detailed discussion of the role played by memory, and the nature of self-induced shocks, in an evolutionary population competing for limited resources. Our study builds on a previously introduced multi-agent system [Phys. Rev. Lett 82, 3360 (1999)] which has attracted significant attention in the literature. This system exhibits self-segregation of the population based on the `gene' value p (where 0<=p<=1), transitions to `frozen' populations as a function of the global resource level, and self-induced large changes which spontaneously arise as the dynamical system evolves. We find that the large, macroscopic self-induced shocks which arise, are controlled by microscopic changes within extreme subgroups of the population (i.e. subgroups with `gene' values p~0 and p~1).Comment: 27 pages, 31 figure

    The Costs and Benefits of Introducing Mandatory Hygiene Regulations

    Get PDF
    In an idealised model the costs of capital and maintenance and the resulting flow of income benefits over a period of years enables the analyst to produce computations of present values and internal rates of return that summarise the whole investment process in a micro environment. In approaching an industry investment problem like mandatory hygiene regulations with benefits or costs to other entities involved, identifying the appropriate capital and maintenance costs and the industry and non-industry benefits is a giant task. In this paper, we report an attempt to identify the extra costs involved in the introduction of the regulations where industry recorded data is not available, and an attempt to identify industry and non-industry benefits from modelling market effects when countries impose restrictions on exports of NZ meat products. For the latter we employ the GTAP model and examine the saved costs to NZ when countries do not impose import restrictions on hygiene grounds. The problem involves consideration of private and public costs and benefits and the flow of costs and benefits when inadequate data is only available. Although our results are confined to average responses to the hygiene programme, they do give an indication of the overall necessity for embarking on such programmes in today's trading conditions.HACCP/RMP, Benefit Cost Analysis, Meat, New Zealand, Food Consumption/Nutrition/Food Safety, International Relations/Trade,

    Evolutionary quantum game

    Get PDF
    We present the first study of a dynamical quantum game. Each agent has a `memory' of her performance over the previous m timesteps, and her strategy can evolve in time. The game exhibits distinct regimes of optimality. For small m the classical game performs better, while for intermediate m the relative performance depends on whether the source of qubits is `corrupt'. For large m, the quantum players dramatically outperform the classical players by `freezing' the game into high-performing attractors in which evolution ceases.Comment: 4 pages in two-column format. 4 figure
