Populism has become a pervasive concept in political science research. However, a central and basic question remains unanswered: which European parties are more populist than others? Despite the increasing wealth of studies on populism in parties, we lack data that measures populism in political parties in a valid and precise manner, that recognizes that populism is constituted by multiple dimensions, and that ensures full coverage of all parties in Europe. In this article, we first appraise the weaknesses of existing approaches. Arguing that parties’ populism should be measured as a latent construct, we then advocate a new approach to operationalizing and measuring populism in political parties using expert surveys. Relying on the Populism and Political Parties Expert Survey spanning 250 political parties in 28 European countries, we show that populism is best measured in a multi-dimensional and continuous manner. We subsequently illustrate the advantages of our approach for empirical analysis in political science.

In this article the authors develop a new approach to the study of policy dynamics in a quasi-federal system of government. The goal is to contribute to previous research on comparative federalism by analyzing the variations of issue attention between levels of government and across four regional governments—Andalusia, Catalonia, Galicia, and the Basque Country. To do so the authors follow the policy dynamics approach, developing a comparative and empirical analysis about issue attention across time, territories, and policy subsystems. The analysis relies on an extensive database, created following the methodology of the Comparative Agendas Project, which includes all laws passed from the early 1980s to present. The results indicate that legislative agendas have become increasingly diverse since the 1990s, and this is partly explained by party preferences and the type of government.

New Approach

The 2021 Nobel Prize in Economic Sciences was awarded to David Card, Joshua Angrist, and Guido Imbens for advancing methodology to establish casual relationships in economics. Their approach brought the notion of the natural experiment, situations in which heterogeneous reactions of different groups of people to chance shocks or policy changes allows to elicit causal effects, to the forefront of empirical analysis, and spearheaded a revolution in development of statistical methods needed to analyze the data. After the initial contributions in labor economics and economics of education, the new approach has become a new standard in economic sciences.

Introduction. The work is devoted to the formation of new conceptual criteria for the effectiveness of international cooperation in the context of the geo-economic space digital transformations. The introduction spells out the general content of the modern geo-economic space and stipulates the need for a conceptually new approach to determining the effectiveness of interaction in this space. Theoretical analysis reveals the methodology for studying synergetic efficiency, substantiates the parameters of synergistic efficiency. Empirical analysis. The real events of the modern geo-economic space, which set the vector of synergetic efficiency of international interaction, are analyzed. Results. The content of a new geo-economic space in the context of digital transformations is disclosed. The features of international cooperation are revealed, which, due to the blurring of national borders, goes into the supranational level of interaction. The irrelevance of classical and traditional approaches to substantiating the effectiveness of cooperation in new conditions is shown, which necessitates the development of conceptually new criteria.

The One

Retractable plate structure (RPS) is a family of structures that is a set of cover plates connected by revolute joints. There exists wide range of possibilities related with these structures in architecture. Configuring the suitable shape of rigid plates that are able to be enclosed without any gaps or overlaps in both closed and open configurations and eliminating the possibility of contact between the plates during the deployment have been the most important issues in RPS design process. Many researchers have tried to find the most suitable shape by using kinematical or empirical analysis so far. This study presents a novel approach to find the suitable shape of the plates and their assembly order without any kinematical or empirical analysis. This approach is benefited from the one-uniform mathematical tessellation technique that gives the possibilities of tiling a plate using regular polygons without any gaps or overlaps. In the light of this technique, the shape of the plates is determined as regular polygons and two conditions are introduced to form RPS in which regular polygonal plates are connected by only revolute joints. It should be noted that these plates are not allowed to become overlapped during deployment and form gaps in closed configuration. Additionally, this study aims to reach a single degree-of-freedom (DoF) RPS. It presents a systematic method to convert multi-DoF RPS into single DoF RPS by using the similarity between graph theory and the duality of tessellation.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

The Cross

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.
