The goal of this study was to propose a hierarchically nested classification system comprising four principal levels of the Braun-Blanquet system for Polish grasslands of the class <em>Molinio-Arrhenatheretea</em>. Using the Cocktail method, we defined consistent criteria for delimitation of the class, three orders, nine alliances, and 45 associations. Formal definitions were prepared using the summed cover and presence/absence information of species groups and individual dominant species. We created an expert system with a set of assignment rules that unambiguously classify relevés to a single unit at the given abstraction level of the Braun-Blanquet system in such a way that a relevé matched by the definition of a focal vegetation unit must be matched by definitions of all superior units. Of 11,535 relevés classified to <em>Molinio-Arrhenatheretea</em>, 36% were recognized at the association level, and 57% and 85% at the alliance and order level, respectively. All relevés were assigned unambiguously, meaning that a single relevé could not be assigned to more than one unit within the same hierarchical level (no overlap between vegetation units). This study is the first proposal of a hierarchically nested classification system that classifies grassland vegetation at different syntaxonomical levels unequivocally. It is important to create definitions for different syntaxonomical levels because the majority of vegetation patches do not fit to the associations, but can only be assigned to high-rank units such as alliance, order, or class.

Carici-Genistetea lobelii Klein 1972 corresponds to cyrno-sardinian oromediterranean cushion scrub and related grasslands. In France, this class is only present in Corsica and the syntaxonomic scheme is debated among phytosociologists. The aim of this paper is to highlight the main plant associations of Carici-Genistetea lobelii Klein 1972 and to define the diagnostic species for each phytosociological unit. We compiled 519 vegetation plots and we applied EuropeanVegetationChecklist expert system for the classes of European vegetation to retain only vegetation plots belonging to Carici-Genistetea lobelii. We obtained a dataset with 189 vegetation plots and we classified them with Modified TWINSPAN classification. Our analyses recognized 6 plant associations and 3 sub-associations already described in the literature; and to describe a new alliance corresponding to the supra-mediterranean vegetations (Genistion salzmannii), a new association (Brimeuro fastigiatae-Juniperetum nanae) and its sub-association (alnetosum suaveolentis). For each of them, we identified diagnostic, constant and dominant species and produced their distribution map. Formal definitions were then written for each phytosociological unit (from subassociation to class) and grouped in an expert system to automatically classify the vegetations of Carici-Genistetea lobelii.

Dry Grasslands in the Slovenský Kras MTS (Slovakia) and the Aggteleki-karszt MTS (Hungary) — A Comparison of Two Classification ApproachesThe paper brings numerical classification of 48 new phytosociological relevés of dry grassland vegetation from the Slovenský kras Mts and the Aggteleki-karszt Mts located on the border between Slovakia and Hungary (Central Europe). We performed a comparison of two classification approaches (an unsupervised method - modified TWINSPAN, and a supervised approach - electronic expert system based on formal definitions of associations), which were applied on the same dataset. Four associations were distinguished:Campanulo divergentiformis-Festucetum pallentisZólyomi (1936) 1966,Poo badensis-Caricetum humilis(Dostál 1933) Soó ex Michálková in Janišová et al. 2007,Alysso heterophylli-Festucetum valesiacae(Dostál 1933) Kliment in Kliment et al. 2000 andFestuco rupicolae-Caricetum humilisKlika 1939. A newly recorded stand of the rareStipetum tirsaeMeusel 1938 association is characterised. What is more, we established a neotype of theAlysso heterophylli-Festucetum valesiacaeassociation.

The aim of this article is threefold: It attempts to 1) identify the characteristics of East Asian forms of meditation, as compared to meditation in other parts of the Eurasian continent; 2) test the usefulness of a definition of meditation as a self-administered technique for inner transformation; and 3) test the usefulness of a classification of meditation techniques based on generic features of the meditation object, in particular location (external vs. internal), agency (spontaneous vs. produced), and faculty (cognitive vs. sensory). While the variation among East Asian forms of meditation is considerable, they (along with Indic forms) are often more technical and less consistently devotional than their Western counterparts, and less often sound-based than their Indic counterparts. In a number of ways, both the definition and classification system suggested turn out to be helpful in the analysis of East Asian forms of meditation.

The Given

Stalking, as currently conceptualized, is a complex phenomenon, and individual stalking cases can be quite distinct. Several authors have proposed classification schemes in an effort to discern and understand common themes among cases of stalking. These stalking “typologies” reflect both theoretical considerations and empirical examinations of persons whose behaviors have shaped the definition of stalking. Typologies have been constructed from clinical and law enforcement perspectives. Classification schemes to date have been broadly based on factors such as the motivation of the stalker, psychiatric symptoms among stalkers, the nature of the relationship between the pursuer and the victim, victim characteristics, and harm to the victim. These classifications have been conceptualized to assist with risk assessment, risk management, and treatment considerations in stalking cases. This chapter describes some historical underpinnings of classification categories, compares existing typologies of stalkers, and explicates the typological scheme adopted throughout this book. Over the last 15 years, stalking has become increasingly recognized as a distinctive form of potentially criminal behavior that may come to the attention of mental health professionals. At the same time that the criminal justice system has grappled with defining stalking for legal purposes, clinicians who encounter stalking behavior have attempted to create useful classifications of stalking behaviors. Attempts have also been made to develop taxonomies of stalking types that might guide law enforcement professionals. Taxonomic classifications are common in science and, when they are successful, they help us organize and identify unique aspects of information and refine our understanding of the given phenomenon under study. Setting up a system of classification of stalking, a behavior that is difficult to define and codify, has several advantages. Once established, a useful taxonomy of stalkers could improve communication among professionals and could help them better appreciate aspects of stalking, including the natural course of the behavior and prognosis of particular stalkers. In addition, taxonomic categorization can facilitate case comparisons and improve clinicians’ abilities to assess risks, manage risks, and provide treatment. Stalking typologies may also enlighten decisions about social policy and legal regulation related to the phenomenon.

The Given

The aim of the given work is to identify and classify the types of political discourses that (may) exist in any particular society. Compared to existing definitions and classifications, our purpose serves a practical goal of schematic classification of political discourses. The article intends to give a starting point for a general classification and typology that will be elaborated within the framework of future research, as typology of discourse specimens is the least developed area of the field (van Dijk, 1997). Definitions/typologies that have been made until now are more of a theoretical character and, therefore, it would be useful to create more concrete mental pictures (expressed in the forms of schemata) that will enable us to operate easier with the concepts discussed while studying the subject. The article starts with the general definition of the term(s) and links the concept of discourse to other concepts like narrative, frame, ideology, discursive strategy. As we try to show the ideology/narrative/discourse link, formulation of corresponding schemes also gain importance in order to have a clearer mental picture of the above mentioned correlation. In parallel with the above mentioned points we also emphasize correlation between the dominant / secondary discourses with specific focus on ideological differences/power struggle.

The given article is devoted to the analysis of modern linguists and interpreters view on the classification of translation types on the whole, and the definition of sight translation as a specific type of professional activity in particular. Universal and specific characteristics of the sight translation with other types of interpretation are revealed. Special problems of authentic text translation, their reasons and the ways of their solving are considered. Complicated (minus) and facilitated (plus) factors performing sight translation are highlighted. The necessary skills for the students to perform visual-oral translation are determined. The authors present two types of sight translation: the training sight translation and the professional one, thus enabling to consider sight translation as a specific professional activity. Sight translation algorithm of actions is considered in the article: familiarization with the text, its «pre-translation analysis» with type, genre, stylistic features, topic identification and the further work on the translation-text creation. Additional sources of information are indicated in order to provide «background knowledge» about the authentic text, they are dictionaries, encyclopedias, instructions, various reference books and manuals. It is recommended to create a terminology dictionary for students’ specialties that help to overcome the lexical barrier and master the particular specialty vocabulary.

Abstract:In 1987, the American Rheumatism Association issued a set of criteria for the classification of rheumatoid arthritis (RA) to provide a uniform definition of RA patients. Fuzzy set theory and fuzzy logic were used to transform this set of criteria into a diagnostic tool that offers diagnoses at different levels of confidence: a definite level, which was consistent with the original criteria definition, as well as several possible and superdefinite levels. Two fuzzy models and a reference model which provided results at a definite level only were applied to 292 clinical cases from a hospital for rheumatic diseases. At the definite level, all models yielded a sensitivity rate of 72.6% and a specificity rate of 87.0%. Sensitivity and specificity rates at the possible levels ranged from 73.3% to 85.6% and from 83.6% to 87.0%. At the superdefinite levels, sensitivity rates ranged from 39.0% to 63.7% and specificity rates from 90.4% to 95.2%. Fuzzy techniques were helpful to add flexibility to preexisting diagnostic criteria in order to obtain diagnoses at the desired level of confidence.

The article raises the problem of classification of the concepts of computer science and informatics studied at secondary school. The efficiency of creation of techniques of training of pupils in these concepts depends on its solution. The author proposes to consider classifications of the concepts of school informatics from four positions: on the cross-subject basis, the content lines of the educational subject "Informatics", the logical and structural interrelations and interactions of the studied concepts, the etymology of foreign-language and translated words in the definition of the concepts of informatics. As a result of the first classification general and special concepts are allocated; the second classification — inter-content and intra-content concepts; the third classification — stable (steady), expanding, key and auxiliary concepts; the fourth classification — concepts-nouns, conceptsverbs, concepts-adjectives and concepts — combinations of parts of speech.

Subject. This article deals with the issues of determining the market value of the trading business, taking into account a number of characteristics. Objectives. The article aims to develop certain provisions of the methodology and practice of evaluating the business of trading organizations, namely, taking into account the additional risk of inventory feasibility when calculating the discount rate. Methods. For the study, we used a systems approach, and the cognition, and economic and analytical research methods. Results. The article presents a three-tiered classification of stocks and a definition of risk based on the criteria for dividing stocks by purpose, degree of implementation, and shelf life in accordance with the scale. Based on the classification, the article offers certain recommendations for determining the discount rate when evaluating trading organizations, aimed at taking into account additional risk. Conclusions. Various evaluation procedures within the framework of traditional approaches and methods in relation to trading organizations do not take into account risk specific to this type of economic activity. The proposed methodology for calculating the discount rate for trade organizations takes into account the features of their functioning.
