Логическая операция транзитивности при принятии решений: междисциплинарная область изучения психологии и экономики
The paper looks into the contemporary state of the problem of decision-making and preference of some alternatives over others, discussing intransitivity of relations of superiority: one object is superior to another in a certain aspect, while the second is superior to the third and the third is superior to the first (A>B, B>C, C>A). The authors analyze two broad groups of theories and empirical studies reflecting opposite views on the nature of the relations and rationality of intransitivity of relations of superiority. The authors argue that understanding of intransitivity of superiority relations is no less important line of cognitive development than understanding of transitivity; they should be studied as complementary subjects. Thus it is necessary to study individual differences in cognitive sets with regard to transitivity/intransitivity of superiority, as well as individual characteristics of solving problems of that kind.
In the paper I consider the causative constructions in Russian. I examine the use of tense and aspect in constructions with the verbs zastavit’ / zastavljat’ ‘make’ and pozvolit’ / pozvoljat’ ‘let, allow’. I also include the verb delat’ / sdelat ‘make’ in my analysis, though this verb has special syntactic and semantic characteristics.
The striking feature of the causative constructions with eventive subjects is that the tensed forms and temporal adverbs in these constructions do not obligatorily refer to the causing situation. The tensed forms and adverbials sometimes refer only to the caused situation.
I assume that it is the nature of events vs. participants that is responsible for these distinctions. Each dynamic event is associated with some result. I have shown that in some cases what the tense of the causative verb and temporal adverbials refer to is the result of the causing event, and not the causing event in the narrow sense.
In this paper, we study the Maximum Happy Vertices and the Maximum Happy Edges problems (MHV and MHE for short). Very recently, the problems attracted a lot of attention and were studied in Agrawal ’17, Aravind et al. ’16, Choudhari and Reddy ’18, Misra and Reddy ’17. Main focus of our work is lower bounds on the computational complexity of these problems. Established lower bounds can be divided into the following groups: NP-hardness of the above guarantee parameterization, kernelization lower bounds (answering questions of Misra and Reddy ’17), exponential lower bounds under the Set Cover Conjecture and the Exponential Time Hypothesis, and inapproximability results. Moreover, we present an O∗(ℓk)O∗(ℓk) randomized algorithm for MHV and an O∗(2k)O∗(2k) algorithm for MHE, where ℓℓ is the number of colors used and k is the number of required happy vertices or edges. These algorithms cannot be improved to subexponential taking proved lower bounds into account.
This book constitutes the proceedings of the 7th International Conference on Analysis of Images, Social Networks and Texts, AIST 2018, held in Moscow, Russia, in July 2018.
The 29 full papers were carefully reviewed and selected from 107 submissions (of which 26 papers were rejected without being reviewed). The papers are organized in topical sections on natural language processing; analysis of images and video; general topics of data analysis; analysis of dynamic behavior through event data; optimization problems on graphs and network structures; and innovative systems.
In my article, I address the factors which favor using a verb as labile (both transitive and intransitive, with no formal change required).
Haspelmath (1993) proposes that the key feature which conditions a way of marking (in)transitivity of verbs in the transitive / intransitive verb pair is the spontaneity parameter.
However, the statistical analysis of Haspelmath’s data shows that for labile / ambitransitive verb the main parameter is the lexical semantic class of the verb, not the degree of spontaneity. This lets us discover a more general principle: phenomena which are not purely grammatical, but rather lexico-grammatical (as lability) depend on lexical features, not on generalized grammatical or semantic parameters.
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This article describes the expierence of studying factors influencing the social well-being of educational migrants as mesured by means of a psychological well-being scale (A. Perrudet-Badoux, G.A. Mendelsohn, J.Chiche, 1988) previously adapted for Russian by M.V. Sokolova. A statistical analysis of the scale's reliability is performed. Trends in dynamics of subjective well-being are indentified on the basis the correlations analysis between the condbtbions of adaptation and its success rate, and potential mechanisms for developing subjective well-being among student migrants living in student hostels are described. Particular attention is paid to commuting as a factor of adaptation.
