The induced 2-tuple linguistic generalized ordered weighted averaging (2-TILGOWA) operator is presented. This new aggregation operator extends previous approaches by using generalized means, ...order-inducing variables in the reordering of the arguments and linguistic information represented with the 2-tuple linguistic approach. Its main advantage is that it includes a wide range of linguistic aggregation operators. Thus, its analyses can be seen from different perspectives and we obtain a much more complete picture of the situation considered and are able to select the alternative that best fits with our interests or beliefs. We further generalize the 2-TILGOWA by using quasi-arithmetic means and Choquet integrals. The result is the Quasi-2-TILOWA operator and the 2-tuple linguistic induced quasi-arithmetic Choquet integral aggregation. We conclude this paper by analysing the applicability of this new approach in a multi-person linguistic decision-making problem concerning product management.

We present the induced generalized ordered weighted averaging (IGOWA) operator. It is a new aggregation operator that generalizes the OWA operator, including the main characteristics of both the ...generalized OWA and the induced OWA operator. This operator uses generalized means and order-inducing variables in the reordering process. It provides a very general formulation that includes as special cases a wide range of aggregation operators, including all the particular cases of the IOWA and the GOWA operator, the induced ordered weighted geometric (IOWG) operator and the induced ordered weighted quadratic averaging (IOWQA) operator. We further generalize the IGOWA operator via quasi-arithmetic means. The result is the Quasi-IOWA operator. Finally, we present a numerical example to illustrate the new approach in a financial decision-making problem.
The Journal of Travel & Tourism Marketing (JTTM) is a leading international journal in "Marketing" and "Tourism, Leisure and Hospitality Management." JTTM published its first issue in 1992. In 2017, ...the journal has celebrated its twenty-fifth anniversary. For that reason, this study analyzes all the publications in the journal since its creation by using a bibliometric approach. The objective is to provide a complete overview of the main factors that affect the journal. This analysis includes key issues such as the distribution of annual publications and citations, the most cited papers, the h-index, citations per paper, the keywords that are mostly used, the influence on the publishing industry and authors, universities, and the countries that have the most publications. The paper uses the Scopus database to analyze the bibliometric data. Additionally, the paper also uses the visualization of similarities (VOS) viewer software to map graphically the bibliographic material. The graphical analysis uses bibliographic coupling, co-citation, citation, and co-occurrence of keywords. These results indicate that JTTM is one of the leading journals in the areas where the journal is indexed, with publications from a wide range of authors, institutions, and countries around the world.
This paper investigates a novel induced ordered weighted averaging (IOWA) distance operator and its application in Pythagorean fuzzy (PF) multiattribute group decision making (MAGDM). First, a new ...induced aggregated distance operator named the weighted IOWA distance (WIOWAD) operator is developed, which differs from the existing methods in that it considers the dual roles of the order‐inducing variables at the same time. In other words, in addition to inducing the order of the arguments, the order‐inducing variables of the WIOWAD operator also plays an important role in moderating the associated weight vector. Some useful properties and different families of the WIOWAD are also discussed. Then, an extension of the WIOWAD within the PF situation is presented, thus obtaining the PFWIOWAD operator. Furthermore, a MAGDM method based on the PFWIOWAD is introduced. Finally, the practicality and effectiveness of proposed approach are illustrated in a research and development project selection problem.

Bibliometrics is a discipline that analyzes bibliographic material from a quantitative perspective. It is very useful for classifying information according to different variables, including journals, institutions and countries. This paper presents a general overview of research in the fuzzy sciences using bibliometric indicators. The main advantage is that these indicators provide a general picture, identifying some of the most influential research in this area. The analysis is divided into key sections focused on relevant journals, papers, authors, institutions and countries. Most of the results are in accordance with our common knowledge, although some unexpected results are also found. Note that the aim of this paper is to be informative, and these indicators identify most of the fundamental research in this field. However, some very influential issues may be omitted if they are not included in the Web of Science database, which is used for carrying out the bibliometric analysis.
The Journal of Psychology: Interdisciplinary and Applied is a leading international journal in psychology dating back to 1935. This study examines its publications since its creation utilizing a ...bibliometric analysis. The primary objective is to provide a complete overview of the key factors affecting the journal. This analysis includes such key issues as the publication and citation structure of the journal, its most cited articles, and the leading authors, institutions, and countries referenced in the journal. The work uses the Scopus database to classify the bibliographic material. Additionally, the analysis provides a graphical mapping of the bibliographic data by using visualization of similarities viewer software. This software uses several bibliometric techniques including co-citation, bibliographic coupling and co-occurrence of keywords. The Journal of Psychology is strongly connected to most of the current leading journals in psychology, and currently has a 5-year impact factor of 1.77 (Thomson Reuters, 2015 Journal Citation Reports).
Purpose
The aim of this study is to reveal the contribution that Journal of Business & Industrial Marketing has to scientific research and its most influential thematic work in B-to-B since its ...beginning in 1986 until 2015, in commemoration of the 30th anniversary.
Design/methodology/approach
The paper begins with a qualitative introduction: the emergence of the magazine, its origins, editorial and positioning. Subsequently, it is based on bibliometric methodologies to develop quantitative analysis. The distribution of annual publications is analyzed, the most cited papers, the keywords that are mostly used, the influence on the publishing industry and authors, universities and the countries that have the most publications.
Findings
The predominant role of the USA at all levels is highlighted. It also highlights the presence (given its size and population) of the countries of Northern Europe. There is great interest in appreciating the evolution of the number of publications that are always increasing which demonstrates the growing and sustained interest in these types of articles, with certain times of retreat (often coincide with economic crisis).
Research limitations/implications
The Scopus database gives one unit to each author, university or country involved in the paper, without distinguishing whether it was one or more authors in the study. Therefore, this may bring some deviations in the analysis. However, the study considers some figures with fractional counting to partially solve these limitations.
Practical implications
After observing the different perspectives of the journal’s production, it allows to give an objective view of the evolution that the Journal of Business & Industrial Marketing has had in the past 30 years.
Originality/value
It is part of the trend that several journals (Journal of Marketing, Journal of Public Policy & Marketing, Journal of Marketing Research, Journal of Business Research) made special sections to show progress and contribution of these journals to scientific research.
The Information Systems Journal (ISJ) published its first issue in 1991, and in 2015, the journal celebrated its 25th anniversary. This study presents an overview of the leading research trends in ...the papers that the journal has published during its first quarter of a century via a bibliometric and ontological analysis. From a bibliometric perspective, the analysis considers the publication and citation structure of the journal. The study then develops a graphical analysis of the bibliographic material by using visualization of similarities software that employs bibliographic coupling and cocitation analysis. The work produces an ontological framework of impact and analyses the journal papers to assess qualitatively ISJ's impact. The results indicate that the journal has grown significantly over time and is now recognized as one of the leading journals in information systems. Yet challenges remain if the journal is to meet its aims in impacting and setting the agenda for the development of the Information Systems field.
Purpose
– The purpose of this paper is to study the effect of online social networks on firm performance and how this technology can help to create value. The authors approach the problem from the ...Resource-Based View in order to analyze if online social networks can be considered source of competitive advantage and how it can enhance or complement essential marketing competences.
Design/methodology/approach
– The data were obtained from a survey based on the Spanish hospitality firms. This sector was chosen because Web 2.0 is becoming an important marketing channel in the tourism industry, and especially in hospitality firms. In addition, Spain is the one of the largest tourist destination in the world and has a strong presence of social media and Web 2.0 use by the population and hospitality enterprises. Between February and June 2012, the questionnaire was sent to all top managers of four-star and five-star Spanish hospitality firms. The authors received 197 questionnaires, but four of them were eliminated due to errors or because they were received too late.
Findings
– Results show that there is a statistically significant positive relationship between online social networks and innovation capacity and that the relationship between online social networks and firm performance is fully mediated by innovation capacity. In turn, the authors find a statistically significant positive relationship between innovation capacity and performance in the hotel industry.
Originality/value
– The authors discuss the importance of online social networks in the development of innovation competences through business intelligence and knowledge management that result in higher performance. The authors also consider the ways in which online social networks enhance knowledge management.
