Country of Origin Advertising and U.S. Wine Imports

The objective of this paper is to investigate the impact of media advertising on the US consumption of imported wine. A panel data of seven countries and twelve years from 1994-2005 is used to estimate the demand function for US wine imports. Our empirical analysis reveals evidence of strong price and advertising effects of domestic and imported wines on imported quantities; the advertising of imported wines significantly increases the quantity of imports while the advertising of domestic wines has a strong depressing effect on imported wine volumes. Our short-run import demand price and advertising elasticity estimates are -0.406 and 0.109 for imports and 0.654 and -0.370 for domestic wines, respectively. Other determinants such as population, real income and country specific fixed effects are also found significant. Based on our model estimates, we compute the marginal return to advertising to be $2.68 on average for the six importing countries and$3.40 for the U.S.International Relations/Trade, Marketing,

Listening Project

In an effort to better serve Southeast and Coastal Georgia, The Coastal Rivers Water Planning & Policy Center tapped the thoughts of several key stakeholders on water issues in our region.The Center was created in 2001 with a continuing mission to "assist policymakers in the formulation of policy designs to best manage sustainable economic growth and natural resource conservation via water planning, research, education and technical assistance." In order to best accomplish this mission, it is necessary for us to engage stakeholders in our region to determine those issues of critical importance.The Listening Project is designed to identify the perspective of water users throughout the Coastal Rivers Region by listening to the actual concerns and ideas for improvement of those who have a stake in the water future of the region. Using this information, the Center can better meet the research needs of stakeholders in the region.The objective of the first round of listening sessions is to identify issues, and not to take a quantitative measure of any given constituency. Thus, the results of the process do not lend themselves to conclusions that any one constituency has a certain viewpoint, but rather gives an idea for the type of issues that arise when representatives of one particular constituency gather to discuss their hopes and fears around the future of water use in Coastal Georgia region.The balance of this paper is organized in the following way: In Section II we discuss the process used in this first round of five listening sessions. In Section III we report the verbatim ideas of the participants in each of the five sessions. Section IV reports the same verbatim ideas put forward by the participants, but the ideas are organized according to dominant themes emerging from the sessions, where various constituencies' ideas on each theme are easily readable in the same place. Finally, in Section V we offer concluding remarks and describe our plans for Phase II of the project. Working Paper Number 2005-00

Hard limits on the postselectability of optical graph states

Coherent control of large entangled graph states enables a wide variety of quantum information processing tasks, including error-corrected quantum computation. The linear optical approach offers excellent control and coherence, but today most photon sources and entangling gates---required for the construction of large graph states---are probabilistic and rely on postselection. In this work, we provide proofs and heuristics to aid experimental design using postselection. We derive a fundamental limitation on the generation of photonic qubit states using postselected entangling gates: experiments which contain a cycle of postselected gates cannot be postselected. Further, we analyse experiments that use photons from postselected photon pair sources, and lower bound the number of classes of graph state entanglement that are accessible in the non-degenerate case---graph state entanglement classes that contain a tree are are always accessible. Numerical investigation up to 9-qubits shows that the proportion of graph states that are accessible using postselection diminishes rapidly. We provide tables showing which classes are accessible for a variety of up to nine qubit resource states and sources. We also use our methods to evaluate near-term multi-photon experiments, and provide our algorithms for doing so.Comment: Our manuscript comprises 4843 words, 6 figures, 1 table, 47 references, and a supplementary material of 1741 words, 2 figures, 1 table, and a Mathematica code listin

A meta-analysis of transdiagnostic cognitive behavioural therapy in the treatment of child and young person anxiety disorders

Background: Previous meta-analyses of cognitive-behavioural therapy (CBT) for children and young people with anxiety disorders have not considered the efficacy of transdiagnostic CBT for the remission of childhood anxiety. Aim: To provide a meta-analysis on the efficacy of transdiagnostic CBT for children and young people with anxiety disorders. Methods: The analysis included randomized controlled trials using transdiagnostic CBT for children and young people formally diagnosed with an anxiety disorder. An electronic search was conducted using the following databases: ASSIA, Cochrane Controlled Trials Register, Current Controlled Trials, Medline, PsycArticles, PsychInfo, and Web of Knowledge. The search terms included “anxiety disorder(s)”, “anxi∗”, “cognitive behavio∗, “CBT”, “child∗”, “children”, “paediatric”, “adolescent(s)”, “adolescence”, “youth” and “young pe∗”. The studies identified from this search were screened against the inclusion and exclusion criteria, and 20 studies were identified as appropriate for inclusion in the current meta-analysis. Pre- and posttreatment (or control period) data were used for analysis. Results: Findings indicated significantly greater odds of anxiety remission from pre- to posttreatment for those engaged in the transdiagnostic CBT intervention compared with those in the control group, with children in the treatment condition 9.15 times more likely to recover from their anxiety diagnosis than children in the control group. Risk of bias was not correlated with study effect sizes. Conclusions: Transdiagnostic CBT seems effective in reducing symptoms of anxiety in children and young people. Further research is required to investigate the efficacy of CBT for children under the age of 6

Ion-mediated conformational switches

Molecular switches are ubiquitous in Nature and provide the basis of many forms of transport and signalling. Single synthetic molecules that change conformation, and thus function, reversibly in a stimulus-dependent manner are of great interest not only to chemists but society in general; myriad applications exist in storage, display, sensing and medicine. Here we describe recent developments in the area of ion-mediated switching
