The primary purpose of this paper is to aggregate the overall rating based on guests’ online ratings by performing a social choice analysis of online hotel rating. Specifically, we first define the individual preference as the subjective judgement on the important order of the dimensions of online hotel rating, then quantify the individual preference through an analytical approach, the pessimistic and optimistic results of which are balanced by the Hurwicz criterion approach, lastly formulate the social choice result by means of the ideal-point concept. An empirical study using the real data collected from Trip.com is conducted to show the applicability and superiority of our methodology.

Abstract. When analysing the performance of hydrological models in river forecasting, researchers use a number of diverse statistics. Although some statistics appear to be used more regularly in such analyses than others, there is a distinct lack of consistency in evaluation, making studies undertaken by different authors or performed at different locations difficult to compare in a meaningful manner. Moreover, even within individual reported case studies, substantial contradictions are found to occur between one measure of performance and another. In this paper we examine the ideal point error (IPE) metric – a recently introduced measure of model performance that integrates a number of recognised metrics in a logical way. Having a single, integrated measure of performance is appealing as it should permit more straightforward model inter-comparisons. However, this is reliant on a transferrable standardisation of the individual metrics that are combined to form the IPE. This paper examines one potential option for standardisation: the use of naive model benchmarking.

The method provided in this paper can be according to the current population to readjust the weight, thus obtain toward the positive ideal point search pressure, finally converge to the optimal solution. This paper combines the feasible direction into genetic algorithm. This method can lead the individual to optimal solution region along feasible direction which approach the optimal solution sets. Through evaluating the degree of distance between chromosome and constrain, we introduce membership function into traditional GA and embed the information of infeasible solutions into fitness function. Propose a self-adapting evaluation function. This method can readjust the weights according to current group and then get the stress of searching to the ideal positive point. To a kind of fuzzy multi-objective optimization problem, propose a method of best satisfaction to transform the fuzzy models to clear ones and solve the models using GA based on interactive method. Then testify its validity though examples.

This article discusses the basic concepts of Berdyaev’s philosophy, traces the relationship of his philosophical view and political convictions. This relationship is revealed through the concept of personality, which is the central concept of Berdyaev’s philosophy. Through the attitude to the personality, we can reveal the attitude of N. A. Berdyaev to the institution of the state, understand the social preferences of the Russian philosopher, who has come a long way from the representative of Russian Marxism to Russian religious philosophy. Having understood his ideas about the ideal structure of society, we can understand the attitude of N. A. Berdyaev to the Soviet state. The article distinguishes between two different types of relationships: the individual and society - collectivism and communitarianism. Berdyaev’s view is shown in the origins of Russian communism, which, in the opinion of the philosopher, are found not only in Western European philosophy, but also in the historical mentality of Russian people.

The aim of this paper is to clarify the continuing debate about the theoretical characteristics of vote trading. It sets about this by first emphasizing existing distinctions among types of vote trading systems, most importantly, the distinction between trades on entire platforms characterizing social states (implicit vote trading) and trades on the individual issues making up the platforms (explicit vote trading). The subdivisions of the latter type are more carefully explored, with the key results being that: while all vote trading systems may lead to circularity in the attempt to choose; and while implicit vote trading inevitably involves such circularity; vote trading over individual, independent issues may be stable. The challenge to the social choice field is therefore to be more careful in specifying the conditions of foresight, renegotiability and the like, and to compare theoretical systems for explicit vote trading with actual legislative rules.

The article is about the frankoznavchyi experience of one of the most productive researchers of the Ukrainian diaspora, the well-known Ukrainian scientist, journalist and editor Luka Lutsiv (1895-1984). First of all, about his monograph “Ivan Franko is a fighter for national and social justice” (1967). The importance of L. Lutsiv’s work provides not only for a complex illustration of I. Franko’s life and creative work, taking into account various com- plex moments, not only for a simple, lively presentation of the leading ideas, not only for the argumentative refutation of the valuations of the Soviet Franco studies, but also for the use of classical methods of research. The methodological base of his work was biographism (closely related to the cultural-historical approach) and hermeneutics. In the mono- graph we have not only the desire of the researcher to go deep into the artist’s biography and the cultural-historical context of the epoch, but also to protect Franko from the Soviet falsifications and to get to the essence of his creative work – the “truth” (in the terminology of classical philosophy). A literary scholar through the going out of the funda- mental hermeneutic layers understands this “truth”: the deep meanings, values, ideals and imperatives of the writer’s creative work, however, without more concrete terminological definitions. The work is also about the interpretation valuations of L. Lutsiv through the prism of main imperatives, which he identified in Ivan Franko, that is, categorical orders that appear at the same time as the main regulative idea of thinking and the system-forming element of the ideological base of the individual. The first leading imperative for the researcher is the national imperative (the “ideal of independence”), which re- veals the national-centered (natsiosofskyi, natsionalistychnyi or natsiolohichnyi) component of I. Franko’s worldview. Another central imperative of I. Franko’s life and creative work is the social imperative associated with the problem of social justice. One can state that L. Lutsiv’s monograph, despite all the possible defects, today thanks to the classical methodological base can be positioned not only as a document of the epoch but also as a valuable scientific source, though probably not as academic but as a popular science genre. This study helps to understand I. Franko’s worldview and thinking as a definite integrity, as a complex system and gives significant impulses for the continuation of episte- mological studies of this kind.

The multicriteria ABC inventory classification has been widely adopted by organizations for the purpose of specifying, monitoring, and controlling inventory efficiently. It categorizes the items into three groups based on some certain criteria, such as inventory cost, part criticality, lead time, and commonality. There has been extensive research on such a problem, but few have considered that the judgments about criteria’s importance order usually exhibit a substantial degree of variability. In light of this, we propose a new methodology for handling the multicriteria ABC inventory classification problem using the social choice theory. Specifically, the pessimistic and optimistic results for all possible individual judgments are obtained in a closed-form manner, which are then balanced by the Hurwicz criterion with a “coefficient of optimism”. The CRITIC (Criteria Importance Through Intercriteria Correlation) method is used to aggregate the individual judgments into a collective choice, according to which the items are classified into Groups A, B, and C. Through a numerical experiment, we show that the proposed methodology not only considers all possible preferences among the criteria, but also generates flexible classification schemes.

AbstractI argue that, according to F. H. Bradley’s Ethical Studies, duties of our station (positional duties) are not morally obligatory unless they are required from an ideal point of view. I support my interpretation by showing that Bradley places the ideal point of view higher than the social and requires that what society demands from us is evaluated from that higher point of view. My argument relies on a detailed analysis of “my station and its duties”. The phrase must be understood as a category that (1) refers to different concepts throughout Ethical Studies (i.e. a theory that Bradley rejects, a revised thesis that he accepts, and positional duties), and (2) embraces several theses (descriptive, normative, and ideal), each involving a number of claims, only a few of which Bradley accepts. I argue that Bradley rejects the normative thesis of MSID theory that identifies moral obligation with social requirements because he finds bottom-up idealization (what ought to be must conform to what is) unsatisfactory. Bradley’s inclusion of “my station and its duties” in the moral ideal must be understood as amounting to the claim that a positional duty is morally obligatory only when it is justified by the norms governing pre-institutionalised relationships.

Purpose As hospitals are now being designed with an increasing number of single rooms or cubicles, the individual preference of patients with respect to social contact is of great interest. The purpose of this study is to gain a better understanding of the experience of patients in an outpatient infusion center. Design/methodology/approach A total of 29 semi-structured interviews were conducted, transcribed and analyzed by using direct content analysis. Findings Findings showed that patients perceived a lack of acoustic privacy and therefore tried to emotionally isolate themselves or withheld information from staff. In addition, patients complained about the sounds of infusion pumps, but they were neutral about the interior features. Patients who preferred non-talking desired enclosed private rooms and perceived negative distraction because of spatial crowding. In contrast, patients who preferred talking, or had no preference, desired shared rooms and perceived positive distraction because of spatial crowding. Research limitations/implications In conclusion, results showed a relation between physical aspects (i.e. physical enclosure) and the social environment. Practical implications The findings allow facility managers to better understand the patients’ experiences in an outpatient infusion facility and to make better-informed decisions. Patients with different preferences desired different physical aspects. Therefore, nursing staff of outpatient infusion centers should assess the preferences of patients. Moreover, architects should integrate different types of treatment places (i.e. enclosed private rooms and shared rooms) in new outpatient infusion centers to fulfill different preferences and patients should have the opportunity to discuss issues in private with nursing staff. Originality/value This study emphasizes the importance of a mix of treatment rooms, while new hospital designs mainly include single rooms or cubicles.

By using the standard combining logics technique (D. M. Gabbay 1999) we define a generalization of von Wright?s preference logic (G. H. von Wright 1963) enabling to express, on an almost propositional level, the individual and the social preference relations simultaneously. In this context we present and prove the counterparts of crucial results of the Arrow-Sen social choice theory, including impossibility theorems (K. Arrow 1951 and A. K. Sen 1970b), as well as some logical interdependencies between the dictatorship condition and the Pareto rule, and thus demonstrate the power and applicability of combining logics method in mathematical economics.

The article discusses the problem of reflection in the definition of personality in the context of the works of G.V.F. Hegel, I.G. Fichte, and F. T. Mikhailov. The identity of the origins of science and the origins of personality is revealed through the study of human activity. A historical excursion is conducted with an analysis of the discussion between L.S. Vygotsky and J. Piaget presented in the book «Thinking and Speech». It is shown that it was necessary for F.T. Mikhailov to refer to the Paleolithic era in his study of the essential human ability to perform appropriate self-regulated actions. The article reveals the connection between productive imagination and self-reflection. A critique of the reflection of everyday consciousness is given. The article shows the significance of Kant's third Antinomy of pure reason, which a person always faces when approaching the solution of his own Self. The article also explores the rationale for the development of human creative abilities. It outlines the role of E.V. Ilyenkov’s philosophical concept of the ideal in understanding the nature of the human Self. The points of coincidence of ontogeny and phylogeny in the formation of personality are defined. The article concludes that the social nature of the individual depends on the reflective attitude in the process of object-transformative activity. The issue of subjective understanding of reality through practice is considered.
