The regional dimension of the CAP: 2007-2018
No full textThe Common Agricultural Policy (CAP) is one of the main pillars in constructing the European project. Since 1962, the CAP has evolved from its traditional role of supporting farmers’ livelihood and improving agricultural productivity to embrace balanced territorial development. In the process, it has been implemented across the EU territory in a fashion tailored to the regions’ needs. This report explores a rich data set on disaggregated CAP payments and regional characteristics to describe the regional dimension of the CAP. It does so by identifying and quantifying three relevant dimensions of the policy: the time dimension, associated with the reforms it has undergone in the period of analysis; the spatial dimension by framing its implementation in the rurality context of the EU territory and; the mix dimension by typifying the different implementation models of the policy. This characterization of the CAP and its rural context allows to investigate the regional patterns of its implementation. The study finds clear evidence that the more developed regions tend to benefit from policy mixes with a relatively low contribution from Pillar 2. On the other hand, developing and less developed regions tend to implement a mix of instruments that privilege rural development actions
An Evaluation of the CAP impact: a Discrete policy mix analysis
No full textThe Common Agricultural Policy (CAP) is one of the main pillars in constructing the European project. Since 1962, the CAP has evolved from its traditional role of supporting farmers’ livelihood and improving agricultural productivity to embrace the goal of balanced territorial development. In the process, the CAP has become a policy with many different instruments allowing MS, farmers, and regions to adopt distinct implementation models. This report explores a rich data set on disaggregated CAP payments and regional characteristics to evaluate the CAP as a mix of policies at the EU level. The project aims to showcase the feasibility and value-added of quantitative approaches able to infer causality while considering the diversity of measures deployed in rural areas
Measurement Error Bias Reduction in Unemployment Durations
Get PDFThe impact of duration response measurement error is investigated by using small variance approximations. The inconsistency of GMM estimators that ignore measurement error is studied for both single spell models with right censoring, and for a two spell lagged duration dependence model. The results suggest a corrected GMM estimator for the error free and measurement error distributions. When the error free density is known, identification is achieved by using the moment condition that defines the measurement error sensitive specification score test. The results are applied to unemployment duration data from the BHPS.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Departure from independence and stationarity in a handball match
No full textThis paper analyses direct and indirect forms of dependence in the probability of scoring in a handball match, taking into account the mutual influence of both playing teams. Non-identical distribution (i.d.) and non-stationarity, which are commonly observed in sport games, are studied through the specification of time-varying parameters. The model accounts for the binary character of the dependent variable, and for unobserved heterogeneity. The parameter dynamics is specified by a first-order auto-regressive process. Data from the Handball World Championships 2001-2005 show that the dynamics of handball violate both independence and i.d., in some cases having a non-stationary behaviour.binary choice, dynamic panel data, time-varying parameters, unobserved heterogeneity, dependence, non-stationarity,
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
