Agricultural Market Performance in the EU after the 2000 and 2003 CAP Reform An Ex-post Evaluation based on AGMEMOD

The paper investigates the CAP impacts on the EU agriculture by means of policy simulations conducted with the AGMEMOD model. To isolate the policy effects in the historical period 2000-2005, counterfactual simulations for this period are run. To simulate the response of the EU agriculture on different policy changes in the period 2006-2020, a ‘no-policy change’ baseline scenario is developed and then policy experiments are conducted such as the abolition of milk quota, the implementation of the regional payments and some budget cuts. To identify the policy effects, the policy scenarios are compared with the ‘no-policy change’ baseline.CAP Reform, ex-post evaluation, agricultural sector modelling, Agricultural and Food Policy,

Numerical simulations on the motion of atoms travelling through a standing-wave light field

The motion of metastable helium atoms travelling through a standing light wave is investigated with a semi-classical numerical model. The results of a calculation including the velocity dependence of the dipole force are compared with those of the commonly used approach, which assumes a conservative dipole force. The comparison is made for two atom guiding regimes that can be used for the production of nanostructure arrays; a low power regime, where the atoms are focused in a standing wave by the dipole force, and a higher power regime, in which the atoms channel along the potential minima of the light field. In the low power regime the differences between the two models are negligible and both models show that, for lithography purposes, pattern widths of 150 nm can be achieved. In the high power channelling regime the conservative force model, predicting 100 nm features, is shown to break down. The model that incorporates velocity dependence, resulting in a structure size of 40 nm, remains valid, as demonstrated by a comparison with quantum Monte-Carlo wavefunction calculations.Comment: 9 pages, 4 figure

EU Dairy Quota Reform – AGMEMOD Scenario Analysis

This study provides an in-depth model based quantitative analysis of the implications of the dairy policy reform on the milk and dairy market as well as on other agricultural markets in the EU27, EU15, EU12 and the individual MS. The objectives of the study are threefold: 1. to assess the implications of changing policy and market conditions on EU agriculture with special emphasis on milk quota phasing out and export subsidy removal by using a modelling tool; 2. to carry out policy relevant scenarios reflecting deregulation (e.g. quota abolition), changes in quota and price levels, different types and levels of direct payments; and 3. to analyse the implications of policy reform scenarios and to draw appropriate policy recommendations. Based on an overview of the existing approaches used to analyse the dairy market, the necessary adjustments to the AGMEMOD model are developed. Projections are made under a baseline of no policy change for a time horizon of 10 years for selected individual MS, the EU15 in aggregate, EU12 in aggregate (12 MS from May 2004), and the EU27 in aggregate. This baseline is contrasted with a series of scenarios which involve an increase and eventual elimination of the EU milk quota. The increase in EU milk production under the scenarios is smaller than the increase in milk quota. Milk quota rents fall to zero relatively quickly due to rising input costs and falling milk prices. However, the milk price path under the scenarios is not hugely different to that of the baseline, so it can be said that the general international market conditions in dairy and animal feed are the main drivers of the observed outcomes. In some MS, expansion potential is quite strong and in such cases production continues to expand even after quotas are removed in those scenarios which involve a larger milk quota expansion in advance of its elimination.Milk Quota, Policy Analysis, Partial Equilibrium Modelling., Agricultural and Food Policy,

MODELLING IMPACTS OF SOME EUROPEAN BIOFUEL MEASURES

Against the background of increasing concerns regarding the energy supply security as well as environmental concern the interest for renewable energy sources has increased in recent years. The biofuel sector, backed by public policies, experienced a strong increase in and outside Europe. A methodology that allows for the estimation of the impacts of the fulfilment of the proposed biofuel targets in the EU member states is proposed and implemented in the AGMEMOD model for France and Germany. The so called normative approach, based on the use of a logistic function as biofuel demand function allows to perform simulations to assess the impact of the biofuel demand expansion on agricultural markets. The implemented approach and the simulation results indicate that crops production would adjust to the modified demand situation and depending on the proposed scenario the domestic supply would not be enough for the achievement of the biofuel targets in France and Germany.biofuel targets, biodiesel, ethanol, modelling, Crop Production/Industries, Public Economics, Resource /Energy Economics and Policy,

Who do we inform? The role of status and target in intergroup whistle-blowing

In two experiments (n = 87 and n = 90), we showed that strongly identifying members of a low status group are more likely to actively inform the ingroup rather than the outgroup about an outgroup transgression, and consider it as more loyal to the ingroup to do so. Moreover, strongly identifying members of a high status group are more likely to actively inform the outgroup rather than the ingroup about an outgroup transgression, and consider this to be more loyal to the ingroup. The results are in support of the notion that, depending on a group's existing status position, negative outgroup information can be used to enhance or confirm the ingroup's standing, affecting whether the ingroup or the outgroup will initially be informed about an outgroup transgression.

Lack of Detection of XMRV in Seminal Plasma from HIV-1 Infected Men in The Netherlands

Background: Xenotropic murine leukaemia virus-related virus (XMRV) is a recently discovered human gammaretrovirus with yet unknown prevalence and transmission route(s). Its presence in prostate stromal fibroblasts and prostatic secretions suggests that XMRV might be sexually transmitted. We chose to study a compartment closely connected to the prostate, a location where XMRV was detected in independent studies. Seminal plasma samples from HIV-1 infected men were examined as they have an increased probability of acquiring sexually transmitted pathogens. Methodology/Principal Findings: We studied the prevalence of XMRV in 93 seminal plasma samples of 54 HIV-1 infected men living in The Netherlands with a nested PCR amplification specifically targeting the XMRV gag gene. As a control for the presence and integrity of retrovirus particles, HIV-1 was amplified from the same samples with a PCR amplification targeting the env gene of the virus, or HIV-1 was quantified with a real-time PCR amplifying part of the pol gene. Conclusions/Significance: Although HIV-1 was amplified from 25 % of the seminal plasma samples, no XMRV was detected, suggesting that either the prevalence of XMRV is very low in The Netherlands, or that XMRV is not naturally present in th

Evaluation of sexual history-based screening of anatomic sites for chlamydia trachomatis and neisseria gonorrhoeae infection in men having sex with men in routine practice

<p>Abstract</p> <p>Background</p> <p>Sexually transmitted infection (STI) screening programmes are implemented in many countries to decrease burden of STI and to improve sexual health. Screening for <it>Chlamydia trachomatis </it>and <it>Neisseria gonorrhoeae </it>has a prominent role in these protocols. Most of the screening programmes concerning men having sex with men (MSM) are based on opportunistic urethral testing. In The Netherlands, a history-based approach is used. The aim of this study is to evaluate the protocol of screening anatomic sites for <it>C. trachomatis </it>and <it>N. gonorrhoeae </it>infection based on sexual history in MSM in routine practice in The Netherlands.</p> <p>Methods</p> <p>All MSM visiting the clinic for STI in The Hague are routinely asked about their sexual practice during consulting. As per protocol, tests for urogenital, oropharyngeal and anorectal infection are obtained based on reported site(s) of sexual contact. All consultations are entered into a database as part of the national STI monitoring system. Data of an 18 months period were retrieved from this database and analysed.</p> <p>Results</p> <p>A total of 1455 consultations in MSM were registered during the study period. The prevalence of <it>C. trachomatis </it>and <it>N. gonorrhoeae </it>per anatomic site was: urethral infection 4.0% respectively and 2.8%, oropharynx 1.5% and 4.2%, and anorectum 8.2% and 6.0%. The majority of chlamydia cases (72%) involved a single anatomic site, which was especially manifest for anorectal infections (79%), while 42% of gonorrhoea cases were single site. Twenty-six percent of MSM with anorectal chlamydia and 17% with anorectal gonorrhoea reported symptoms of proctitis; none of the oropharyngeal infections were symptomatic. Most cases of anorectal infection (83%) and oropharyngeal infection (100%) would have remained undiagnosed with a symptom-based protocol.</p> <p>Conclusions</p> <p>The current strategy of sexual-history based screening of multiple anatomic sites for chlamydia and gonorrhoea in MSM is a useful and valid guideline which is to be preferred over a symptom-based screening protocol.</p

Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer.

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC. This identified three additional susceptibility loci at 2q13, 8q24.1 and 12q24.31. Integrated analyses of genes and regulatory biofeatures at each locus predicted candidate susceptibility genes, including OBFC1, a new candidate susceptibility gene for low-grade and borderline serous EOC

Higher harmonic anisotropic flow measurements of charged particles in Pb-Pb collisions at 2.76 TeV

We report on the first measurement of the triangular $v_3$, quadrangular $v_4$, and pentagonal $v_5$ charged particle flow in Pb-Pb collisions at 2.76 TeV measured with the ALICE detector at the CERN Large Hadron Collider. We show that the triangular flow can be described in terms of the initial spatial anisotropy and its fluctuations, which provides strong constraints on its origin. In the most central events, where the elliptic flow $v_2$ and $v_3$ have similar magnitude, a double peaked structure in the two-particle azimuthal correlations is observed, which is often interpreted as a Mach cone response to fast partons. We show that this structure can be naturally explained from the measured anisotropic flow Fourier coefficients.Comment: 10 pages, 4 figures, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/387
