Introduction

Organizational Culture (OC) has been subject of different research since the early 20th century (Nukic & Huemann, 2016). For decades researchers and business professionals have been interested in this subject, especially within American businesses (^{de-la-Garza-Carranza, Guzman-Soria, & Mueller, 2011}; ^{Pietersen, 2017}). Of 1980 to date, more than six thousand scientific research publications on OC in the Web of Science (WoS) database have been published. Currently, OC research presents an increase in the production of publications, in the last three years, the number of publications has increased, as shown by the WoS data.

Web of Science identify publications on Organizational Culture, and it classifies on different research areas (Business economics, Psychology, Social Sciences Other Topics, Health Care Sciences Services, Education Educational Research, Engineering and other). Business economics is the most crucial area of research of OC; it concentrates about forty percent of these publications.

Despite full of publications of Organizational culture topic, ^{Chatman & O'Reilly (2016)} believe that everything related to research in OC is not yet solved and that new researchers have the mission to continue with the research in several aspects that remain unclear.

The aim of this article, through of bibliometric analysis, is to provide useful information on scientific research publications of Organizational culture in the category of Management in the research area of Business economics available in the Web of Science, for researchers interested in the subject.

Organizational Culture (OC). Is defined in different ways (^{Ertosun & Adiguzel, 2018}). For example: how a group of persons learns over a period of time to solves its problems of survival in an external environment and its problems of internal integration (^{Schein, 1990}). For ^{Schneider, Ehrhart, & Macey (2013}) is defined as basic assumptions about the world and values that guide life in organizations.

Analysis of the recent research works and publications proves the multiplication of some scientific works dedicated to the problem of OC (^{Shymko, 2018}). The research of the OC has been profoundly explored based on different definitions of the construct using different types of measurements and from different theories (^{Chatman & O'Reilly, 2016}).

Organizational culture is a crucial aspect of any successful business or organization (^{Kasemsap, Styron, & Styron, 2017}). The OC affects the employees and organizational processes and plays a significant role in companies and, it can bring a competitive advantage to the organization (^{Ertosun & Adiguzel, 2018}). OC can influence the performance and effectiveness of a company and it can be a factor in the success of an organization. (^{Warrick, 2017}). OC is indicative of the typical way of orienting organization members towards common goals (^{Calciolari, Prenestini, & Lega, 2018}).

To increase the effectiveness of the organization, the OC can be used as a critical element to promote long-term effectiveness and that the change efforts of the global culture can manifest not only in results such as the return on investment, assets, or sales, but also in customer satisfaction (^{Gillespie, Denison, Haaland, Smerek, & Neale, 2008}). The personality of the CEO affects the culture of the organization; this culture subsequently affects a broad set of organizational results, such as financial performance, reputation recommendations of reputation analysts and employee attitudes (^{O'Reilly, Doerr, & Chatman, 2018}).

Although researchers have studied for some time the relationship between OC and financial performance, it is not yet clear how this relationship is (^{Chatman, Caldwell, O'Reilly, & Doerr, 2014}). OC can be a powerful force that clearly shows what is essential and coordinates the efforts of members without the cost of the inefficiencies of close supervision within an organization (^{Chatman & Cha, 2003}). Culture can be studied as a part of the process of adaptation of organizations, and that the specific cultural feature can be useful to predict effectiveness and performance (^{Denison & Mishra, 1995}). To determine whether the culture or performance has a causal priority, or, if there is a reciprocal relationship, a longitudinal study was conducted concluding that the culture "comes first" (^{Boyce, Nieminen, Gillespie, Ryan, & Denison, 2015}).

Nowadays, publications on OC is increasing, the consensus on the concept of the construct is diverse, and the impact it causes on the results of the companies remains in discussion.

Bibliometric analysis. Is the quantitative study of bibliographic material, and it can show a general picture of a research field (^{Merigo & Yang, 2017}). Bibliometric analysis is a valuable research tool that can systematically represent the nature of specific scientific disciplines by highlighting critical research points and identifying research trends (^{Zhang et al., 2016}).

Some research has used Bibliometric analysis as a method to indicate trends in different areas, for example: ^{Lopez-Fernandez, Serrano-Bedia, & Perez-Perez (2016)} applied bibliometric indicators in an in-depth and systematic review of the theme of entrepreneurship in family businesses, identifying the most productive authors; through their co-citations and through co-word analysis, identified research trends in the subject. ^{Podsakoff, MacKenzie, Podsakoff, & Bachrach (2008)} used bibliometric techniques to examine 30 research journals in the field of administration, using the number of citations as a basis to determine the impact of research in a defined period of years.

Bibliometrics methods and visualization networks to analyze the publications of the Journal of Uncertainty, Fuzziness and Knowledge-Based Systems in the period 1993-2016 was presented by ^{Wang et al. (2018)} including a general overview of publications, authors, institutions and countries, which were the most relevant function of the number of citations. They also used the VOSviewer software for visualization of different connections between authors, journals and countries.

^{Ozkose & Gencer (2017)} used the bibliometric mapping to analyze in depth Management Information Systems field. The expert opinion defined a sample of 24 journals, this journals of the sample were most important in the area, the bibliometric technique of co-occurrence analysis allowed to establish the most cited terms and keywords through the VOSviewer software that were represented in density maps for natural interpretation.

^{Mascarenhas, Marques, Galvao, & Santos (2017)} based on a bibliometric study using the VOS viewer software to analyze the topic of the Entrepreneurial University based on research published in the WoS from 1900 to the present, they determined the research opportunities for the area. ^{Pecha & Vanecek (2015)} conducted a bibliometric analysis of the research publications on the physiology field in the Czech Republic and Hungary. For this, they used the VOS viewer software and compared the directions of the research and topics of internal research in the area to the world trends.

A bibliometric study of publications in different databases in the last 70 years by ^{Olczyk (2016)} explained the state of the art of the international competitiveness in the discipline of economics. He used in its analysis, bibliometric indicators such as network citation analysis, key-routes main path, and term co-occurrence analysis.

Through of bibliometric citation and co-citation analysis, as well as content analysis of the literature, this article exposes the current situation of the publications on OC research and provide answers to the following question: What are the leading publications, authors and journals in the OC research in Business economics? How publications, authors and journal are a relationship in the OC research in Business economics?

Method

The bibliographic search was conducted in the Web of Science Core Collection database. This database has been widely used in academic research (^{Caputo, Marzi, Pellegrini, & Rialti, 2018}; ^{Castillo-Vergara, Alvarez-Marin, & Placencio-Hidalgo, 2018}; ^{Caya & Neto, 2018}; ^{Mascarenhas et al., 2017}; ^{Merigo & Yang, 2017}; ^{Wang et al., 2018}). Web of Science Core Collection database includes the Citation Indexes: Science Citation Index Expanded (SCI-EXPANDED), Social Sciences Citation Index (SSCI), Arts & Humanities Citation Index (A & HCI), Book Citation Index-Science (BKCIS), Book Citation Index- Social Sciences & Humanities (BKCI-SSH), Emerging Sources Citation Index (ESCI).

First, the term “Organizational Culture” was used in a type of search by topic in WoS. The type of search by topic include the following fields to search for a record of the database: title, abstract, keywords of author and keywords plus. The search refined by research area (Business and Economics) and category of WoS (Management). The search was realized on October 18, 2018, and the range of time from 1980 to October 2018.

The second step was made from the data obtained in the search. A detailed analysis of the information provided by the WoS was made. The publications by year, publications and citations of the principal authors and journals, as well as the most cited articles over the years, were included in tables to facilitate the understanding of the topic.

For the analysis of the data obtained of the search was used the VOSviewer software. VOSviewer is a program that was developed for constructing and viewing bibliometric maps. VOSviewer can, for example, be used to construct maps of authors or journals based on co-citation data or to construct maps of keywords based on co-occurrence data (^{van Eck & Waltman, 2010}). VOSviewer software has been used to construct networks of scientific publications, scientific journals, researchers, research organizations, countries, keywords, or terms. Items in these networks can be connected by co-authorship, co-occurrence, citation, bibliographic coupling, or co-citation links (^{Caputo et al., 2018}; ^{Mascarenhas et al., 2017}; ^{Merigo & Yang, 2017}; ^{Ortiz-de-Urbina-Criado, Najera-Sanchez, & Mora-Valentin, 2018}). For this work, the indicators of citation and co-citation were used to show the relationship between authors, journals and references of the publications obtunded from WoS.

Analysis of Results

Of the search in the WoS, 1936 scientific research publications were obtained, Table 1 shows the distribution of the publications by type of document. Articles are the most important type of document within of the publications; it represents 89.5% of the total of publications of the database in OC in the category of Management in Business Economic research area.

In the other hand, the amount of publications on OC in the WoS from 1994 to the present day is shown in Table 2. In this table, a column specifies the number of total of publications on OC by year in WoS, another column indicates the number of publications on OC in the Management category of Business Economic research area. Although publications of OC is extensive: Over the years, the publications on OC in Management category of Business economics have obtained, in certain years (1995, 1996, 1999, 2003, 2011), more than 40% of the total of publications of the WoS. In annual average, the publications in OC, in the mentioned category and research area, are approximately 33% of the total of publications of the WoS on the subject. The distribution of publications generated over time shows the growing trend of publications on OC. Evolution of the research in the area of OC is shown in Figure 1.

Figure 1 Evolution of Scientific Research in the Field of Organizational culture (1980-2018) 

The total of publications of the WoS on OC increased steadily from 1994 to 2001, it relapses and then in 2002, it recovered and continued with a growth trend until 2012. In 2013, there was a decrease in the number of publications that continued in 2014. In the last three years (2015, 2016 and 2017) there was a significant increase in publications (more than 50%) compared to 2012, which was the year most productive in publications.

The term “Organizational Culture” was used in a type of search by topic in WoS. Here, 6338 scientific research publications were identified. Next, for a refined search in the area of research Business economics in the Management category, 1936 publications were obtained of WoS database. For these publications, 3819 authors were obtained and, 407 journals were identified. Finally, the number total of cited references in these publications is equivalent to 82597 references.

Bibliometric analysis indicated the most productive authors on OC in the Management category of Business Economics research area. Ogbona, Harris, and Denison are the authors with most publications in this category. In another hand, if productivity is based on the measurement of citations of authors have in WoS, Chatman, Cadwell, and Oreily would take the places 1, 2, 3, in the area of research (Table 3).

The co-citation analysis of cited references indicates the number of times that two references are cited at the same time in a publication. In this case, Schein (1985), Schein (1992), Hofstede (1980), Oreilly (1991) and Smircich (1983) present the highest number of citations in the total of publications analyzed. The Table 6 showing the main cited references of OC in Management category in Business economics. The column of the table "total link strength" shows the strength of the relationship exists in the co-citation of the references, that is, among the 25 references that the table contains, as is the co-citation between them in the publications analyzed.

T/O: Total Occurrences, TLS: Total Link Strength

Figure 7 presents the network map formed by the co-citations of the references of the publications of the WoS database on OC in Management category. Each color of bubbles represents different strength of co-citation between the references that make up the group of bubbles of the same color. Three groups were formed in which, Schein. (1985), Schein, (1992), Barney (1986) represent the references with the greatest strength of link in the groups of colored bubbles (green, blue and red respectively). The above indicates that these references with the most active link, are the most co-cited references about the rest of the other references in the database analyzed.

Discussion and Conclusion

Analyzing information derived of all research considered in this article allowed to answer questions presented in reference to knowing who are most cited publications, authors, and sources that had generated knowledge on the subject. Additionally, the co-citation analysis provides an overview useful for researchers interested in the area, offering valuable information for their work.

The bibliometric analysis showed that the Organizational Culture (OC) is maintained as a wealthy research area. The analysis of the 40 most cited publications in WoS on OC in Management of Business economics research area, allows recognizing that new researchers have emerged in the area, generating publications and citations that demonstrate the growth of the research area.

Ogbonna, Harris, and Denison, are the authors with the mayor number of publications of OC in Management in Business economics research area, but they are not the most cited. The authors most cited are Chatman, Caldwell, and Oreilly. The results of the present research concur with ^{Lopez-Fernandez, Serrano-Bedia, & Perez-Perez (2016)} who express: "the most productive authors and journals do not necessarily coincide with those most cited.”

The analysis of co-citations of the references and their VOSviewer map allows us to observe that the oldest and most important reference for their number of citations is Pettigrew (1979). Schein is the author of cited references with the highest number of occurrences, he presents three important base publications distributed in time (1985, 1992 and 2004).

Schein, Hofstede, and Denison present three publications within the 25 most co-cited references each; they are the principal founding authors of OC in the Management of Business economics research area.

It is important to point out that the network maps made by VOSviewer allow observing the interaction that all the selected authors have in the database, showing a great connection of the researchers, promoting the advance on research.

One of the limitations of our research is to consider only the publications in the database of the Web of Science; there are probably publications in other databases that could enrich this study. On the other hand, the research is limited to a category in a research area, a bibliometric analysis that includes all the research areas of OC would provide a broader point of view.
