Intra-European Trade of Manufacturing Goods : An extension of the Gravity Model
In this paper, we propose and test several extensions of the standard gravity model. This yields a specification that allows for (i) a more flexible income response; (ii) a competitiveness effect with a general and a specific component; and (iii) an alternative and consistent measure of remoteness. Those extensions were found to be significant factors to explain intra-EU trade. Next, we analyze the effect of EU harmonization of technical regulations on domestic and intra-EU trade. We find, at different levels of aggregation of the manufacturing sector, that harmonization of regulations has contributed to more intra-EU trade but, apparently, did not affect the so called border effect.
Le prix du vin, qualité ou réputation ?
Dans ce numéro de Regards économiques, nous montrons que les différences de prix observées entre 215 vins de Bordeaux cotés dans un guide réputé dépendent davantage de l'appellation, de la réputation du producteur, du classement de 1855 que des différences en qualité ou en rareté. Même en tenant compte de tous ces effets, certains vins sont offerts sur le marché, du moins temporairement, à des prix anormalement élevés ou très agréablement bon marché.
Development of urban bird indicators using data from monitoring schemes in two large European cities
Bird monitoring projects have provided valuable data for developing biological indicators to evaluate the state of natural and agricultural habitats. However, fewer advances have been made in urban environments. In this study we used bird monitoring data from 2002 to 2012 in two cities with different climates (Brussels and Barcelona), to generate two multi–species urban indicators to evaluate temporal trends on abundance of urban avifauna. To do this we used two different conceptual approaches, one based on a list of widespread species in European cities (WSEC) and another based exclusively on species widespread at city level (WCS) regardless of the birds occurring in other cities. The two indicators gave a similar general pattern, although we found a 3% difference in the mean annual change in both cities, thus suggesting that the values provided by urban indicators may differ depending on the conceptual approach and, hence, by the species list used to generate them. However, both indicators may have their own value and could be treated as complementary indices

Development of an urban bird indicator: using data from monitoring schemes in two large european cities
[eng] Development of urban bird indicators using data from monitoring schemes in two large European cities.— Bird
monitoring projects have provided valuable data for developing biological indicators to evaluate the state of
natural and agricultural habitats. However, fewer advances have been made in urban environments. In this
study we used bird monitoring data from 2002 to 2012 in two cities with different climates (Brussels and Barcelona), to generate two multi–species urban indicators to evaluate temporal trends on abundance of urban
avifauna. To do this we used two different conceptual approaches, one based on a list of widespread species
in European cities (WSEC) and another based exclusively on species widespread at city level (WCS) regardless of the birds occurring in other cities. The two indicators gave a similar general pattern, although we found
a 3% difference in the mean annual change in both cities, thus suggesting that the values provided by urban
indicators may differ depending on the conceptual approach and, hence, by the species list used to generate
them. However, both indicators may have their own value and could be treated as complementary indices.[cat] Desarrollo de indicadores de aves urbanas a partir de datos de sistemas de monitoreo en dos grandes ciudades europeas.— Los proyectos de monitoreo de aves han proporcionado datos valiosos para el desarrollo
de indicadores biológicos que evalúan el estado de los hábitats naturales y agrícolas; sin embargo, los avances
han sido menores en los ambientes urbanos. En este estudio se utilizaron los datos del monitoreo de aves
de dos ciudades climáticamente diferentes (Bruselas y Barcelona; período 2002–2010) para generar dos
indicadores urbanos multiespecíficos que valorasen las tendencias temporales en la abundancia del conjunto
de las aves urbanas. Para hacer esto, utilizamos dos enfoques conceptuales distintos, uno basado en una
lista de especies de amplia distribución en las ciudades europeas (WSEC) y otro basado exclusivamente en
especies de amplia distribución a nivel de ciudad (WSC), independientemente de las aves de otras ciudades.
Los dos indicadores dieron un patrón general similar, aunque un 3% de diferencia entre ellos en cuanto a los
valores de cambio promedio anual se encontró en ambas ciudades. Esto sugiere que los valores producidos
por los indicadores urbanos pueden diferir dependiendo de la aproximación conceptual y, por tanto, por la
lista de especies utilizada para generarlos. Ambos indicadores pueden tener su propio interés y pueden ser
tratados como complementarios
Serum lipoprotein levels in takotsubo cardiomyopathy vs. myocardial infarction
<p>Abstract</p> <p>Background</p> <p>In the setting of myocardial infarction (MI) or acute coronary syndrome (ACS), current guidelines recommend early and aggressive lipid lowering therapy with statins, irrespective of the baseline lipoprotein levels. Takotsubo cardiomyopathy (TCM) patients have a clinical presentation similar to myocardial infarction and thus receive early and aggressive statin therapy during their initial hospitalization. However, the pathology of TCM is not atherosclerotic coronary artery disease and hence we assumed the lipid profiles in TCM would be healthier than coronary artery disease patients.</p> <p>Methods</p> <p>In this retrospective study, we assessed fasting serum lipoprotein levels of ten TCM patients and compared them with forty, age and sex-matched myocardial infarction (MI) patients.</p> <p>Results</p> <p>Comparing serum lipoprotein levels of TCM with MI group, there was no significant difference in mean total cholesterol between the two groups (174.5 mg/dL vs. 197.6 mg/dL, p = 0.12). However, in the TCM group, mean HDL-C was significantly higher (66.87 mg/dL vs. 36.5 mg/dL, p = 0.008), the mean LDL-C was significantly lower (89.7 mg/dL vs. 128.9 mg/dL, p = 0.0002), and mean triglycerides was also significantly lower (65.2 mg/dL vs. 166.8 mg/dL, p < 0.0001).</p> <p>Conclusions</p> <p>In this study, TCM patients in comparison to MI patients had significantly higher levels of HDL-C, lower levels of LDL-C levels and triglycerides. The lipid profiles in TCM were consistent with the underlying pathology of non-atherosclerotic, non-obstructive coronary artery disease. As lipoproteins in most TCM patients were within the optimal range, we recommend an individual assessment of lipid profiles along with their coronary heart disease risk factors for considering long term lipid-lowering therapy. A finding of hyperalphalipoproteinemia or hypotriglyceridemia in 40% of TCM patients is novel but this association needs to be confirmed in future studies with larger sample sizes. These findings may provide clues in understanding the pathogenesis of takotsubo cardiomyopathy.</p
Racial Differences in Exposure and Glucuronidation of the Tobacco-Specific Carcinogen 4-(Methylnitrosamino)-1-(3-Pyridyl)-1-Butanone (NNK)
BACKGROUND; In the United States, Blacks who smoke cigarettes have a higher mean blood concentration of the nicotine metabolite cotinine than White smokers. It has not been determined whether there are racial differences in the exposure to the cigarette smoke carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and in the detoxification of NNK metabolites. METHODS; A community-based cross-sectional survey of 69 Black and 93 White smokers was conducted in lower Westchester County, New York. Information on smoking and lifestyle habits was collected and urinary concentrations of several tobacco smoke biomarkers were compared, including the NNK metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and its glucuronide (NNAL-Gluc). A frequency histogram and probit plot of NNAL-Gluc:NNAL ratios were constructed to determine slow and rapid glucuronidation phenotypes. RESULTS; The mean concentrations of total NNAL, urinary cotinine, plasma cotinine, and thiocyanate were significantly higher in Black men than in White men for each cigarette smoked. In women, the only biomarker that was significantly elevated in Blacks was plasma cotinine. A higher proportion of White versus Black women was categorized as "rapid" glucuronidators (two-tailed exact test, P = 0.03). In men, there were no significant differences in NNAL-Gluc:NNAL phenotypes. CONCLUSIONS; The higher rates of lung carcinoma in black men may be due in part to a higher level of exposure to tobacco smoke carcinogens
Contrasting population trends of Common Starlings (Sturnus vulgaris) across Europe

Contrasting population trends of Common Starlings (Sturnus vulgaris) across Europe
The greatest loss of biodiversity in the EU has occurred on agricultural land. The Common Starling (Sturnus vulgaris) is one of the many numerous and widespread European farmland breeding bird species showing major population declines linked to European agricultural intensification. Here we present results based on monitoring data collected since 1975 in 24 countries to examine the influence of changing extent of grassland and cattle abundance (based on results of earlier studies showing the importance of lowland cattle grazed grassland for the species), wintering provenance and temperature on national breeding population trends of Starlings across Europe. Positive Starling population trends in Central-East Europe contrast with negative trends in North and West Europe. Based on this indicative approach, we found some support for the importance of cattle stock and no support for grassland, temperature or wintering provenance to explain Starling population trends in Europe. However, we acknowledge such a European-wide analysis may conceal regional differences in responses and suggest that currently accessible national land use datamight be insufficient to describe the detailed current changes in animal husbandry and grassland management that may be responsible for changes in food availability and hence breeding Starling abundance and their differences across Europe. Reviewing results from local studies relating Starling population trends to local agricultural change offer contradictory results, suggesting complex interacting processes at work. We recommend combining national datasets on demography, land-use/agricultural practices and from autecological research to better explain the reasons for contrasting Starling trends across Europe, to enable us to predict how changing agriculture will affect Starlings and potentially suggest mitigation measures to restore local populations where possible.Peer reviewe
