Two disparate views emerge as rural people living along Timor-Leste's south coast are confronted by extractive industries charged with implementing a large oil infrastructure project: emphasis is put either on the productive potential of non-human environment or spiritual connections particular sites. While political ontology approaches posit that resource conflicts reveal underlying ontologica...

Governments use national debt and the budget deficit as measures of fiscal position. But what should government policy aim to achieve with respect to these measures? Are these the right summary measures at which to be looking? This paper considers what the government should use as its fiscal targets to achieve policies that are consistent with long-term fiscal objectives. Among its findings are...

BACKGROUND The main objective of flux balance analysis (FBA) is to obtain quantitative predictions of metabolic fluxes of an organism, and it is necessary to use an appropriate objective function to guarantee a good estimation of those fluxes. METHODOLOGY In this study, the predictive performance of FBA was evaluated, using objective functions arising from the linear combination of different ...

| We present results concerning three diierent types of quartic (fourth order) time-frequency distributions. First, we present new results on the recently introduced local ambiguity function, and show that it provides more reliable estimates of instantaneous chirp rate than the Wigner distribution. Second, we introduce the class of quartic, shift-covariant, time-frequency distributions, and inv...

The paper investigates the properties of ambiguity functions of 2-D analytic, quaternionic and monogenic signals. In the introduction the notions of the above signals and their Wigner distributions and ambiguity functions are recalled. The properties of the ambiguity functions are investigated using two kinds of test signals: A band-pass test signal in the form of a sum of two harmonic signals ...

The connection between the Wigner function and the generalized OTF, and between the ambiguity function and the generalized OTF is investigated for non-paraxial scalar wavefields. The treatment is based on two-dimensional (2-D) wavefields for simplicity, but can be extended to the three-dimensional case.

The Medicaid program has become increasingly complex as policymakers use it to address various policy objectives, leading to structural tensions that surface with Medicaid managed care. In this article, we illustrate this complexity by focusing on the experience of three States with behavioral health carveouts--Maryland, Oregon, and Tennessee. Converting to Medicaid managed care forces policyma...

The objective of this paper is to show how ambiguity, and a decision maker (DM)’s response to it, can be modelled formally in the context of a general decision model. We introduce a relation derived from the DM’s preferences, called ‘‘unambiguous preference’’, and show that it can be represented by a set of probabilities. We provide such set with a simple differential characterization, and argu...

According to the well-known distinction attributed to Knight (1921), there are two kinds of uncertainty. The first, called “risk,” corresponds to situations in which all events relevant to decision making are associated with obvious probability assignments (which every decision maker agrees to). The second, called “(Knightian) uncertainty” or (following Ellsberg (1961)) “ambiguity,” corresponds...
