8. The importance of test order in external and standardized test results: The case of PISA 2018.

Abstract

Standardized tests intend to reduce information asymmetry by providing a common and objective measure of students' academic performance. The basic assumption underlying standardized testing is that differences in student performance on standardized tests should be attributed primarily to differences in the quality of education received by students. However, there is evidence that environmental factors can affect standardized test scores, which may result in anomalous observations or outliers that show a distortion of student performance. In this regard, the exclusion of Spain from PISA 2018 is particularly interesting as Spanish data met PISA 2018 Technical Standards but showed implausible student-response behavior. The aim of this paper is to complement the OECD's analysis of Spain's exclusion from PISA 2018 by exploring the potential reasons behind the outlier results, focusing on the Madrid region.

12. A semantic approach for the requirement-driven discovery of web services in the Life Sciences

Author

Perez, Maria, Berlanga, Rafael, and Sanz, Ismael

Subjects
Computer Science - Artificial Intelligence, J.3
Abstract

Research in the Life Sciences depends on the integration of large, distributed and heterogeneous data sources and web services. The discovery of which of these resources are the most appropriate to solve a given task is a complex research question, since there is a large amount of plausible candidates and there is little, mostly unstructured, metadata to be able to decide among them.We contribute a semi-automatic approach,based on semantic techniques, to assist researchers in the discovery of the most appropriate web services to full a set of given requirements., Comment: in Adrian Paschke, Albert Burger, Andrea Splendiani, M.

17. What do OECD countries cut first at a time of fiscal adjustments? A dynamic panel data approach

Author

Abstract

Following the present atmosphere of budgetary cuts we analyze the effects of fiscal consolidation on the composition of government expenditures by functions. Using a dynamic voter group decision model and exploiting the panel structure of the dataset – 26 OECD countries over the period 1970-1997- by GMM estimation we find that fiscal adjustments protect social expenditure. Nevertheless, we find that among social expenditure, those being also productive such as education and health are even more protected than those not being productive as social welfare expenditure. Moreover, fiscal adjustments do not fall primarily over the most productive expenditure, transport and communications, but over defense and economic services.

Abstract

This paper presents an approach for analysing food-porn images and their related comments published by the cooking school Getcookingcanada Instagram account. Our approach processes the published images to extract colour parameters, counts the number of likes, and also analyses the comments related to each publication. A dataset containing all these was built, and methods were applied to study correlations among the data: a regression analysis, an ANOVA and a sentiment analysis of the comments on the dataset to explain the relation between the quantity of likes and the sentiment obtained from the food images. Our results show a correlation between the number of likes and the sentiment analysis of the comments. Images that evoke a positive sentiment have a higher number of likes and comments. Users’ experience on creating posts is also analysed and confirms a positive correlation between the number of likes and the publisher’s experience

38. Is the transposition of EU directives homogeneous? An AI counterfactual example.

Abstract

This research investigates homogeneity in the transposition of European Directives using as an example the EU policy on tobaccos regulated by Directive 2011/64. We analyse the effect of excise duties on tobacco consumption in Europe from 2002 to 2017 using an Artificial Intelligence counterfactual strategy. To our knowledge, this the first time that this AI strategie has been used in the economic analysis of law. Our results show that countries have different responses to changes in prices or taxation on tobacco. The lack of homogeneity across countries creates distortions and frontier effects and shows the need of harmonization. [ABSTRACT FROM AUTHOR]

39. Fiscal decentralization and economic growth: spending versus revenue decentralization

Abstract

This article examines whether the efficiency gains accompanying fiscal decentralization generate higher growth in more decentralized economies, applying pooled-mean group techniques to a panel dataset of 23 Organization for Economic Co-operation and Development (OECD) countries, 1972-2005. We find that spending decentralization has tended to be associated with lower economic growth while revenue decentralization has been associated with higher growth. Since OECD countries are substantially more spending than revenue decentralized, this is consistent with Oates' (1972) hypothesis that maximum efficiency gains require a close match between spending and revenue decentralization. It suggests reducing expenditure decentralization, and simultaneously increasing the fraction financed locally, would be growth-enhancing. (JEL E62, H71, H72), I. INTRODUCTION Fiscal decentralization (hereafter: FD) is a political economy trend in both developing and developed countries. According to the World Bank (1999), some 95% of democracies now have elected [...]

49. Has European Economic integration affected the functional composition of government expenditures?

Abstract

Globalization and growth-maximizing governments may cause countries to converge toward a similar composition of government expenditures. These convergent forces may be even more intensive in the case of EU member states engaged in the European integration process. The results obtained, through calculation of a constructed dissimilarity index and by adapting the usual indicators of convergence (β, σ, and γ), reveal that there has been a harmonization process. In addition, this approximation of the structures of government expenditures has been greater in the EU than in the non-EU countries of the OECD. Nevertheless, EU member states are converging toward a different steady-state composition of government expenditures. (JEL H11, H50, H60), I. INTRODUCTION The globalization process has led to a growing interdependence of fiscal policies affecting, inter alia, the composition of government expenditures. Sanz and Velazquez (2004) show that there was [...]
