There are many studies which implement and assess existing measurement manners and document the progress of entities towards the circular economy (CE) at various levels, or present or propose new possibilities of measurement. The majority of them refer to the micro level. The aim of this paper is to conduct a multidimensional comparative analysis of the implementation of circular economy by EU countries. After an in-depth critical analysis of the literature, CE indicators which were proposed by the European Commission were adopted as a basis. Owing to the research population-Member States of the European Union (EU-28), focusing on the said indicators was declared reasonable in all aspects. The classification of EU countries according to the level of their advancement in the concept of CE was adopted as a main research task. In order to do so, a relevant index of development of circular economy was created (IDCE). This will allow us, inter alia, to trace changes in the spatial differentiation of advancement of the EU countries in implementing CE over the years, to identify CE implementation leaders as well as countries particularly delayed in this regard. The comparative analysis was conducted by means of statistical methods. On the basis of the analyses, it was concluded that among all EU countries, those of the old EU are the most advanced in terms of CE. The analysis confirmed significant rising trends for IDCE only in the case of Belgium and The Netherlands.

Increasing interest in analyzing human gait using various wearable sensors, which is known as Human Activity Recognition (HAR), can be found in recent research. Sensors such as accelerometers and gyroscopes are widely used in HAR. Recently, high interest has been shown in the use of wearable sensors in numerous applications such as rehabilitation, computer games, animation, filmmaking, and biomechanics. In this paper, classification of human daily activities using Ensemble Methods based on data acquired from smartphone inertial sensors involving about 30 subjects with six different activities is discussed. The six daily activities are walking, walking upstairs, walking downstairs, sitting, standing and lying. It involved three stages of activity recognition; namely, data signal processing (filtering and segmentation), feature extraction and classification. Five types of ensemble classifiers utilized are Bagging, Adaboost, Rotation forest, Ensembles of nested dichotomies (END) and Random subspace. These ensemble classifiers employed Support vector machine (SVM) and Random forest (RF) as the base learners of the ensemble classifiers. The data classification is evaluated with the holdout and 10-fold cross-validation evaluation methods. The performance of each human daily activity was measured in terms of precision, recall, F-measure, and receiver operating characteristic (ROC) curve. In addition, the performance is also measured based on the comparison of overall accuracy rate of classification between different ensemble classifiers and base learners. It was observed that overall, SVM produced better accuracy rate with 99.22% compared to RF with 97.91% based on a random subspace ensemble classifier.

Introduction. The article is devoted to the description of pottery ceramics on Mordovian territory. The purpose of the article is to analyze the development of ceramics in Mordovian region. The object of the article is a collection of ceramics of Mordovian republican S.D. Erzia Fine Art Museum, the subject – the main features of the ceramics based on the morphological analysis of its exhibits. Materials and Methods. The material of the study was the results of the research of Russian scholars on ceramics of antiquity and modernity, as well as empirical materials presented by the ceramics funds of Mordovian republican S.D. Erzia Fine Art Museum. One of the main approaches implemented in the article is a comparative analysis of the exhibits based on the color of the shard. It allows the author to systematize utensils according to their functional purpose, and also to make an assumption about the various historical stages of the emergence of different types. Results and Discussion. The article systematizes the variety of forms of ceramics, reveals their quantitative relationships, the prevailing forms, and gives the comparative analysis of the existing forms. The classification of vessels was carried out in accordance with a number of criteria: the height and thickness of the neck, the design of the corolla cut, the diameter of the mouth and the maximum extension of the trunk, which allows one to draw conclusions about the similarity of the collection’s exhibits with other Mordоvian artefacts. Conclusion. It concludes about the existence of a certain standard in the production of ceramic dishes, and on the similarity of the studied ceramics and the collections of Russian monuments. Therefore, it states the preservation of local Mordovian pottery traditions in the course of wide interactions with Russian pottery ceramics.

Complex Variety

Genetically modified organisms have been at the centre of a major public controversy, involving different interests and actors. While much attention has been devoted to consumer views on genetically modified food, there have been few attempts to understand the perceptions of genetically modified technology among farmers. By investigating perceptions of genetically modified organisms among Brazilian farmers, we intend to contribute towards filling this gap and thereby add the views of this stakeholder group to the genetically modified debate. A comparative analysis of our data and data from other studies indicate there is a complex variety of views on genetically modified organisms among farmers. Despite this diversity, we found variations in such views occur within limited parameters, concerned principally with expectations or concrete experiences regarding the advantages of genetically modified crops, perceptions of risks associated with them, and ethical questions they raise. We then propose a classification of prevailing profiles to represent the spectrum of perceptions of genetically modified organisms among farmers.
