    Valuing Transgenic Cotton Technologies Using a Risk/Return Framework

    No full text
    Stochastic Efficiency with Respect to a Function (SERF) is used to rank transgenic cotton technology groups and place an upper and lower bound on their value. Yield and production data from replicated plot experiments are used to build cumulative distribution functions of returns for nontransgenic, Roundup Ready, Bollgard, and stacked gene cotton cultivars. Analysis of Arkansas data indicated that the stacked gene and Roundup Ready technologies would be preferred by a large number of risk neutral and risk averse producers as long as the costs of the technology and seed are below the lower bounds calculated in this manuscript.cotton, financial risk, market value, SERF, transgenic, Agribusiness, Crop Production/Industries, Risk and Uncertainty, Q12, Q16,

    Agricultural Policies and Risk Management: A Holistic Approach

    No full text
    This paper discusses the main issues and driving forces of government policies in the area of risk management in agriculture, with particular emphasis on good policy practices and the international environment. Four main ideas are developed. First, good policy and good policy analysis requires a holistic approach. This is particularly so in this policy area because risks interact prominently with both farm household strategies and government programs and regulations in terms of risk reduction impacts and the development of market tools and strategies. Second, the rational for government actions which are based on market failure or equity concerns need to be defined in order to analyze its nature and scope, as well as to develop appropriate government measures. Third, the context of all support measures to agriculture must be considered because there are potential risk-related effects associated with most forms of support, particularly in OECD countries with high level of support to agriculture. Fourth, risk management measures need to comply with international agreements, particularly the Agreement on Agriculture of the World Trade Organization. Implications for good policy in this area have already been drafted by OECD and are useful for policy analysis.

    Matthew’s Emmanuel Messiah: a paradigm of presence for god's people

    No full text
    The motif of divine presence is a clear phenomenon within the Gospel of Matthew. The modern critical means for assessing the ancient biblical text have multiplied to the point, some claim, of disparity. This study employs both narrative and redaction criticism in an attempt to respond authentically to the structural, historical and theological dimensions of Matthew's Gospel. This study begins with the presumption of the wholeness and integrity of Matthew's narrative, and assumes the gospel story to have an inherently dramatic structure which invites readers to inhabit imaginatively its narrative world and respond to its call. But since we are concerned with the role of both reader and author, this study also assumes a text with an historical author and context. The introduction focuses on the meta-critical dilemma facing New Testament students - what is the text and how do we read it? - and seeks some balance in terms of Krieger's analogy of the text as both window and mirror. Proposed is a narrative reading of Matthew's presence motif alongside a redaction critical assessment of it. In Chapter 2 the elements of narrative theory are introduced and relevant terms defined: the structure of narrative, the function of the narrator, points of view. Chapter 3 becomes an exercise in narrative reading, with Matthew's presence motif providing the focus, and the implied reader’s interaction with the story being predominant in interpretation. Characters, rhetorical devices, and points of view are discussed, to understand the motif's development throughout the story's progress. The thrust of Chapter 4 is thereafter to examine divine presence as a dominant motif within Matthew's most important literary context: the Jewish scriptures. Here the primary paradigms of divine presence provided by the Patriarchs, the Sinai experience, and the Davidic-Zion traditions are assessed. Chapter 5 follows with a more detailed examination of the OT "I am with you/God is with us" formula and its µeo' vµwv/ηuwv language, so strongly connected to Matthew's presence motif. Chapters 6-8 build on these investigations with a closer analysis of the three critical "presence passages" of Mt 1:23. 18:20 and 28:20. The passages and their contexts are probed from a redaction critical perspective, guided by the narrative investigation of Chapter 3, and the background from Chapters 4 and 5.The three major "presence passages" examined in Chapters 6-8 are also complimented by a number of secondary issues: worship, wisdom, the Spirit and the poor in Matthew, and their relation to Jesus' divine presence. These are discussed in Chapter 9. Chapter 10 summarizes and looks briefly at some implications. Matthew' presence motif proves to be an important element of the Gospel’s rhetorical design, redactional strategy and Christology. The presence of Jesus, the Emmanuel Messiah, exhibited in his risen authority, becomes the focus of his people's hopes and experiences in the post-Easter world. What the presence of Yahweh was to his people. Jesus now provides in a new paradigm for his people - his followers, the little ones, the poor and the marginalized, from all nations

    NOTES ON PARALLELIZING ATM-TN CELL-LEVEL SIMULATION MODELS

    No full text
    This is a facts finding study for parallelizing ATM-TN simulation models. ATM-TN stands for ATM Traffic and Network. It is a frame work for detailed cell level ATM simulation models. The users are responsible for providing network topology and specifying parameters for each component of the network being modeled. To a large extent, the principles presented in this report also apply to other cell level ATM simulation models. The purpose of the study is to find out what is the available parallelism in this type of ATM-TN models, how to parallelize the models in general, and what problems there are to be addressed for the Time Warp mechanism to get reasonable speedup with the ATM-TN simulation given the very small granularity of the simulation models.We are currently acquiring citations for the work deposited into this collection.

    Tensor network Kalman filter for LTI systems

    No full text
    An extension of the Tensor Network (TN) Kalman filter [2], [3] for large scale LTI systems is presented in this paper. The TN Kalman filter can handle exponentially large state vectors without constructing them explicitly. In order to have efficient algebraic operations, a low TN rank is required. We exploit the possibility to approximate the covariance matrix as a TN with a low TN rank. This reduces the computational complexity for general SISO and MIMO LTI systems with TN rank greater than one significantly while obtaining an accurate estimation. Improvements of this method in terms of computational complexity compared to the conventional Kalman filter are demonstrated in numerical simulations for large scale systems.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Raf Van de PlasTeam Jan-Willem van Wingerde

    Synthesis and immunological evaluation of N-acyl modified Tn analogues as anticancer vaccine candidates

    No full text
    Tumor-associated carbohydrate antigens (TACAs), which are aberrantly expressed on the surface of tumor cells, are important targets for anticancer vaccine development. Herein, several N-acyl modified Tn analogues were synthesized and conjugated with carrier protein CRM197. The immunological results of these glycoconjugates indicated that 6-CRM197 elicited higher titers of antibodies which cross-reacted with native Tn antigen than the unmodified 2-CRM197 did. The IFN-gamma-producing frequency of lymphocytes in mice treated with 6-CRM197 was obviously increased, compared to that of mice vaccinated with 2-CRM197 (p = 0.016), which was typically associated with the Th1 response. Moreover, the elicited antisera against antigen 6-CRM197 reacted strongly with the Tn-positive tumor cells, implying the potential of this glycoconjugate as an anticancer vaccine.

    Measurements and a model for convective velocities in the turbulent boundary layer

    No full text
    A physical model is presented which describes convective velocities within a flat plate turbulent boundary layer. A production zone concept is used as a basis for the physical model. The production zone concept employs the idea that packets of turbulent fluid are generated near the viscous sublayer. These packets are found to be discernible from the mean motion and may move either outward from the production zone or inward depending on their circulation relative to the fluid surrounding the packet. The packets are predicted to travel with a convective velocity different from the local mean velocity throughout most of the boundary layer. The model also predicts that the convective velocities will be functions of wave number outside the production zone

    Jackson's theorem for compact connected Lie groups

    No full text
    AbstractWe prove that for f ϵ E = C(G) or Lp(G), 1 ⩽ p < ∞, where G is any compact connected Lie group, and for n ⩾ 1, there is a trigonometric polynomial tn on G of degree ⩽n so that ‖f − tn‖E ⩽ Crωr(n−1,f). Here ωr(t, f) denotes the rth modulus of continuity of f. Using this and sharp estimates of the Lebesgue constants recently obtained by Giulini and Travaglini, we obtain “best possible” criteria for the norm convergence of the Fourier series of f
