Poland Divided: Spatial Differences in the June 2003 EU Accession Referendum. Jean Monnet/Robert Schuman Paper Series, Vol. 4 No. 1, January 2004

(From the introduction). Thus, our purpose here is to describe and analyze geographical patterns within Poland of approval, disapproval, and abstention from this crucial vote on joining the EU, and to link those outcomes to the social and economic situation obtaining in the regions. From these associations we can shed additional light on how Poland divided on this pivotal issue and posit some challenges for both Polish and EU policy makers in the years ahead. To guide us we refer to several studies of the emergence of electoral politics in former- Soviet states (notably Russia and Ukraine) and in Central and Eastern Europe that have pointed to the salience of geographical differences in voting outcomes and voter turnout in the postcommunist period. (7) Complementing research based on individual level, or survey, data, these geographic studies using aggregate data relate variations in the social, economic, and demographic traits of regions to party, candidate, and issue preferences across these same units. For example, it has been almost universally the case in the post-communist countries that rural, older, agricultural populations have voted mainly for parties of the left and against reform, while urban, better-educated, white collar areas have, for the most part, favored parties and candidates that have advocated reform and privatization. These outcomes match very closely the kinds of divisions within societies that we find in surveys. Clearly, however, we must recognize the limitations of aggregate data analysis, especially the need to avoid imputing individual action from collective figures. Surveys, of course, have advantages over one-time aggregate data, including their ability to probe attitudes and to conduct sampling over time. However, polling results have their own limitations especially that they tend to be a–spatial (and therefore cannot usually be used to illuminate important regional issues), and that respondents are not always truthful, particularly on sensitive subjects. But taken together, survey and aggregate data provide us with a higher degree of confidence in the analysis of the correlates of voting behavior. Following the methodology used in these other geographic studies of post-communist states, here we will test several propositions relating to the affinity for EU membership within different segments of Poland’s electorate. We will do this by cross-tabulating results of the June accession referendum with key social and economic variables among the 373 powiaty of Poland. According to the administrative reform of 1999, Poland is divided into 16 provinces (województwa, or voivodships), which are in turn divided into sub-regions (podregiony) and further into the powiaty. (8) The powiat scale of analysis is ideal for our purposes; powiaty are “county” level units or individual cities “with powiat status” (what we will call here “urban powiaty”) that provide an excellent degree of spatial resolution and, most importantly, for which the Polish government provides superb, detailed socioeconomic data and electoral results. (9) Powiaty typically range from 50,000 to 150,000 inhabitants and between 500-2,000 km2. Urban powiaty range from relatively small to medium-sized urban centers with populations around 100,000 people to the largest cities such as Poznań (572,000), Wrocław (624,000), Kraków (741,000) and Łódz (786,526). The Warsaw conurbation comprises the powiat of Warsaw (1.610 million). (10) As will be seen, there is a remarkable diversity within Poland—not unexpectedly in such a large and heterogeneous country—with regard both to social and economic conditions and to the demonstrated preferences of voters, with the two being related

Nutritional and Defensive Chemistry of Three North American Ash Species: Possible Roles in Host Performance and Preference by Emerald Ash Borer Adults

Black ash (Fraxinus nigra), green ash (F. pennsylvanica), and white ash (F. americana) are the three most abundant ash species in the northeastern USA. We compared emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), adult performance and preference among seedlings of the three ash species, and then related performance and preference to foli- age nutritional quality and defensive compounds. Longevity of EAB adults reared on green and white ash was found to be greater than on black ash. EAB adult females also seemed to show feeding preference among the three species of ash trees because the total foliage area consumption was greater on green ash and white ash compared to black ash in dual-choice tests; however, the total mass of foliage consumed did not differ. The foliage of all ash species was high in nitrogen and in most macro- and micro-nutrients studied. The patterns of EAB performance and preference did not correspond to any of the individual chemical compounds tested (nitrogen, proteins, most macro- and micro-nutrients, or putative defensive compounds of ash seedlings). Never- theless, greater longevity of EAB adults on green and white ash compared to black ash was probably related to unbalanced nutrients (total nitrogen/total non-structural carbohydrate ratio) of black ash. Putative defensive compounds (i.e., phenolics and protease inhibitors) did not contribute to EAB longevity in this study, probably because (1) EAB adults were able to excrete most of these compounds and (2) their effects were alleviated by high nitrogen levels. More research is needed to elucidate the interactions of nitrogen and carbohydrate levels, and the interactions of nutrient balance and defensive plant allelochemicals on EAB performance and preference

Conformal Bootstrap in the Regge Limit

We analytically solve the conformal bootstrap equations in the Regge limit for large N conformal field theories. For theories with a parametrically large gap, the amplitude is dominated by spin-2 exchanges and we show how the crossing equations naturally lead to the construction of AdS exchange Witten diagrams. We also show how this is encoded in the anomalous dimensions of double-trace operators of large spin and large twist. We use the chaos bound to prove that the anomalous dimensions are negative. Extending these results to correlators containing two scalars and two conserved currents, we show how to reproduce the CEMZ constraint that the three-point function between two currents and one stress tensor only contains the structure given by Einstein-Maxwell theory in AdS, up to small corrections. Finally, we consider the case where operators of unbounded spin contribute to the Regge amplitude, whose net effect is captured by summing the leading Regge trajectory. We compute the resulting anomalous dimensions and corrections to OPE coefficients in the crossed channel and use the chaos bound to show that both are negative.Comment: 40 pages, 1 figure; V2: Small corrections and clarification

Flavour physics at the Tevatron

The Tevatron heavy flavor physics program is in full swing. The rapid increase in the size of data samples is allowing significant improvements of previous results, and opens the doors to new possibilities. A further doubling of the current integrated luminosity is expected in the next couple of years. This report summarizes the main current results and future prospects.Comment: Proceedings of invited plenary talk at the Europhysics Conference on High Energy Physics, Krakov, Poland, July 16-22, 2009 (EPS-HEP 2009).

Bootstrapping the Minimal 3D SCFT

We study the conformal bootstrap constraints for 3D conformal field theories with a $\mathbb{Z}_2$ or parity symmetry, assuming a single relevant scalar operator $\epsilon$ that is invariant under the symmetry. When there is additionally a single relevant odd scalar $\sigma$, we map out the allowed space of dimensions and three-point couplings of such "Ising-like" CFTs. If we allow a second relevant odd scalar $\sigma'$, we identify a feature in the allowed space compatible with 3D $\mathcal{N}=1$ superconformal symmetry and conjecture that it corresponds to the minimal $\mathcal{N}=1$ supersymmetric extension of the Ising CFT. This model has appeared in previous numerical bootstrap studies, as well as in proposals for emergent supersymmetry on the boundaries of topological phases of matter. Adding further constraints from 3D $\mathcal{N}=1$ superconformal symmetry, we isolate this theory and use the numerical bootstrap to compute the leading scaling dimensions $\Delta_{\sigma} = \Delta_{\epsilon} - 1 = .58444(22)$ and three-point couplings $\lambda_{\sigma\sigma\epsilon} = 1.0721(2)$ and $\lambda_{\epsilon\epsilon\epsilon} = 1.67(1)$. We additionally place bounds on the central charge and use the extremal functional method to estimate the dimensions of the next several operators in the spectrum. Based on our results we observe the possible exact relation $\lambda_{\epsilon\epsilon\epsilon}/\lambda_{\sigma\sigma\epsilon} = \tan(1)$.Comment: 16 pages, 6 figures; V2: references adde
