In the field of dentistry, the last decade has seen techno- logical progress grow hand in hand with the expansion of scientific publishing indicated, for example, by the fact that the number of articles on finite element analysis published within the field of dentistry is ten times grea- ter than in other fields (4). This increase calls for on- going bibliometric analysis in order to monitor scientificproduction. Several works have evaluated international scientificproduction in dentistry, including Kaur & Gup- ta (5) in India, and Gracio et al. (6) in Brasil. Other arti- cles have focused on production at a national level, for example, the work by Bueno-Aguilera et al. (7) which provided an analysis of Spanishscientificproduction in dentistry from 1993 to 2012.
Despite the prestigious contributions of Ukrainian economists in the past, most particularly with Mikhaîl Tuhan-Baranovsky and even more so with Eugen Slutsky, there is no single indication of the scientificproduction of contemporary economists either in Ukraine or in the Diaspora. This study attempts to fill that gap by using the 1969-3/1995 EconLit data-base to establish the visibility of all identified economists with Ukrainian descendance active in academic, governmental or private areas. The members of the Editorial Board and the Advisory Board of the Ukrainian Economic Review were also examined in order to provide reference to a benchmark group. The method of analysis applied the usual norms of measurement, taking into account the co-authorship factor, to adjust for effective productivity in refereed journals.
Abstract: Tourism is one of the sectors with more dynamism in the world. For the Latin American countries it represents an opportunity of growth and economic and social development. Cuba is making its best efforts to link and base its economy to this ever-growing field. The presently article carried out a bibliometric analysis of the scientific investigations about tourism in general and on the tourist product, starting from the year 1975. That scientificproduction was formally and thematically characterized through several bibliometric indicative, standing out the productivity for authors, the chronological variation of the number of works published in this field, idiomatic productivity, the areas in those that they have been carried out, among other elements of interest for this study type. The objective is to verify what is being investigated, and for who, as well as the evolution of the academic expression of the countries in this area, in articles and magazines scientific, which are the main channel of diffusion of this topic at the present time, among other publications which contribute to a better knowledge of the map of the investigation. The analysis presented indications of improvements in the academic participation, what represents the importance of the topic for studies of sustainable tourism and the growth of the sector.
Related Work. Although there are some previous works in the literature that analyze and compare the research production of several countries, here we focus on three specific ones that involve Computer Science research groups in Latin America. Laender et. al.  analyzed the quality of the top Computer Science graduate programs in Brazil and found that they are comparable to programs in North America and Europe w.r.t. publication and graduation rates. In par- ticular, the study showed that the ratio between conference and journal papers in Brazilian programs, around 2.5, was close to the ratio presented by European and North American programs, which ranges from 2.3 to 2.8. Wainer et al.  presented a comparative study of the Brazilian CS scientificproduction with some Latin American (Argentina, Chile, Mexico), European, BRIC (Russia, In- dia, China), and other relevant countries such as South Korea, Australia, and USA from 2001 to 2005. The findings show that Brazil’s scientificproduction is the largest in Latin America, getting close to that of European countries such as Spain and Italy, and almost the same as India and Russia. Menezes et al.  analyzed the characteristics of three coauthorship networks in CS communities formed, respectively, by researchers from Brazil, North America (Canada and USA) and Europe (France, Switzerland and UK). They provided several statis- tics of the three networks and performed a temporal analysis of them over a span of 12 years, from 1994 to 2006. In this paper we not only focus on the overall production of the eight Latin American countries considered, but also analyze the performance of the research groups of the main institutions in each country. The rest of this paper is organized as follows. Section 2 describes the data gath- ered for our analysis, Section 3 discusses our preliminary results, and Section 4 presents some conclusions and insights for future work.
At the national level, the National Superintendence of Higher University Education - SUNEDU , through the licensing process has denied said prerogative to 21 universities (20 private and 1 national), the leading cause was the shortage of scientificproduction (Condition 4: Research lines), and lack of agreement with university academic training (Condition 1: Existence of academic objectives, degrees, degrees and curricula). The study is based on humanistic theory, where the subjects are creative, free and conscious men; able to make and build, forged based on a habit or culture - hence the relationship with production and research culture . It is also based on the contribution of Piaget - psychological and learning theory - which exposes the gradual mental development, and the experience or psychological maturation of the subject for the production of topics or daily actions, managing to merge the previous knowledge with the acquired knowledge, being the result a new knowledge . The social theory, whose approach is directed to what the human group does and thinks, its social structure, norms, laws, the power relations and interrelation of the subjects . Therefore, this last theory goes in parallel with the theory of education, for the emphasis on human values, necessary for the development of an ideal society, which achieves a harmonious coexistence and where anarchy, dehumanization and consumerism do not prevail . The research culture is a set of good practices, proposals and values that allow the resolution of research phenomena through analysis, explanation, production, and communication of the results of a study. The teams must be made up of students, teachers and researchers , , , especially the latter, whose main task is to teach research in situ, so that knowledge transcends, and in time they are established the bases that will be shared by the members of a specific university community . It should be noted that research competencies must be indoctrinated as part of the institutional culture of each country, to strengthen knowledge and the acquisition of experiences , . In this sense, every study must comply with an ethical guideline (rules, norms and truthfulness) , , in order not to inform or produce a document with information not under reality. Scientificproduction is the assessment of knowledge that is expressed in innovative ideas, plans and proposals , which ————————————————
The general contribution of Malaysia science, within this topic area, represents a global participation index of 0.22 with respect to world production in period analysed. Among the countries generating research on SGAs, the most significant, as Table 6 shows, is the United States, whose PI is 29.14, followed by the United Kingdom (PI = 7.94), Germany (PI = 5.93) and Japan (PI = 5.25). But if we consider the productivity of these countries in this area in relation to their overall production in the field of Psychiatry and Neurology, only 2 (Malaysia and Spain) of the 10 largest producers in the period 1996–2015, devote a higher percentage of attention to the study of SGAs (Figure 7). In the analysis of the correlation between PI and the per capita health expenditure of each of the countries with the highest scientificproduction in health sciences, the distribution obtained is quite similar (Figure 8).
However, there are few papers that conduct a literature analysis from a bibliometric perspective, analyzing international publications and with a multidisciplinary coverage. One article constitutes an investigation on the structure and evolution of the theme of open access in journals included in the WoS from 2000 to 2010, based on co-citation analysis. The study finds that open access is an emerging field. The first three prominent papers are Lawrence’s “Free online availability substantially increases a paper’s impact” (2001), Antelman’s “Do open access articles have a greater research impact” (2004) and Swan and Brown’s “Open access self-archiving: An author study” (2005). Harnad is the most influential author, and Journal of the Association for Information Science and Technology (JASIS/JASIST is the most frequently cited journal in the open access literature [ 15 ]. Other studies carry out a literature review examining the relationship between OA status and citation counts of scholarly articles [ 16 ].
In recent years, only three bibliometric studies have been published investigating publication trends in orthodontic research [5–8] but none of them have specifically investigated the field of lingual orthodon- tics. The first  analyzed the 100 most cited articles in orthodontics from 1975 to 2011; the second  ex- plored and compared the publications in three major orthodontic journals over two 5-year periods; the lat- est , identified the most cited articles from 2000 to 2015 based on the h-index. Unlike analyses of other dental specialties such as implant dentistry  or oral surgery , none of these three studies made a complete and rigorous analysis.
From Scopus’ publications the articles will be studied, leaving aside press publications, reviews, session documents, editorials and notes. In order to obtain the information and to simplify the study, several filters were used: two of the ten areas presented by Scopus were used, these are: 1) Business Administration and Accounting, and 2) Economy, Econometrics and Finance. These areas were chosen because they are the most influential topics in accounting science , in articles in Spanish, English and Portuguese. Once the filters were applied, 252 results were obtained, working with 247 data, excluding journals with repeated statements or references with insufficient information to be included in the study. The generable database includes variables such as: name of the published article, year of publication, writing language, type of accounting, scope, period of research, author or authors, country of origin of the first author, gender of the authors, name of the journal where the article was published, and the quartile to which it belongs, area of study, name of the promoter university or institution, country where the university is located, and ranking of the promoter institution.
Electoral debates have been subjected to
extensive study in the United States. However, there is a lack of studies analysing and assessing electoral debates in Spain. Hence, this project seeks to assess the current situation of research in this field. To this end, a bibliometric analysis of journal articles, book chapters, books, congress proceedings and theses, published in the last twenty-five years (1993-2018), was used. Five databases: Dialnet, ISOC, Teseo, Scopus and Web of Science (WOS) were examined. 107 documents were found. The source type, the authorship, the language and the development over time of publications were analysed. As regards journal articles, the following items were studied: the source of the journal, the affiliations, the main research focus, the main debate examined, the subject area, the type of research and the technique most commonly used. The results reveal that, first, the research is mainly disseminated by means of scientific journal articles; second, collaboration between authors is unusual; third, the language most widely used is Spanish, and, fourth, it rarely appears in impact factor journals.

The peculiarity of the flipped classroom method lies in the change of learning roles, where the teacher acquires a secondary role as a guide and the student a primary role as an active agent. The trend of implementation in the stage of higher education is increasing and it is increasingly common to hear teaching experiences that revolve around its application in the classroom. Therefore, this paper aims to assess the effect of the flipped classroom methodology on the academic performance of university students from the studies indexed in the WOS and Scopus databases. A methodology of meta-analysis studies has been followed, with the purpose of measuring the size of the global and particular effect of the researchers and empirically verifying the gain in favour of the experimental or control group. The results show that the difference between groups is statistically significant and most of the studies confirm the increase in academic performance in the experimental group. However, there is evidence of a possible bias in the articles published in favour of the flipped classroom method. Finally, the flipped classroom method is raised as a teaching methodology that can improve academic results and make it easier for students to self-regulate their learning.

Recientemente se viene experimentando un incremento del interés que suscita el turismo como área de investigación de la Ciencia Social, reflejado en la proliferación del número de trabajos publicados tanto a nivel nacional, como a nivel internacional. Este fenó- meno ha tenido su paralelismo con la evolución experimentada por la situación económica de este sector. En efecto, la industria del turismo actualmente constituye un activo motor del desarrollo económico en muchos países, sobre todo en los desarrollados y emergentes (Nel-lo y Pérez, 2007; Moreno y Picazo, 2012). A nivel mundial, según el informe de la World Travel & Tourism Council (WTTC) (Hostelsur, 2018), la producción directa de la industria turís- tica fue de 2,4 billones de dólares en el año 2014, lo que representó el 3,1 % del Producto Interior Bruto (PIB) mundial, y generó 105 millones de empleos. No obstante, si se suman los efectos de arrastre o indirectos, el montante generado fue de 7,6 billones de dólares, lo que suponía el 9,8 % del PIB mundial. Tal es su importancia, que el volumen de negocios de esta actividad económica tuvo un impacto superior al de la industria química (8,6 %), la agricultura (8,5 %), la educación (8,4 %), la industria automovilística (7,0 %) y la actividad bancaria (5,9 %) a nivel mundial. En la misma línea, según la Organización Mundial del Turismo (OMT, 2017), un número cada vez mayor de destinos de todo el mundo se han abierto recientemente al turismo, haciendo del mismo un sector muy dinámico y esencial para el progreso socioeconó- mico. De hecho, se ha observado un crecimiento prácticamente ininterrumpido, a pesar de las crisis económicas y financieras sufridas, mostrando regularmente su fortaleza y resistencia, tal y como se señala en la literatura económica al respecto (Torres, 1994; Massieu, 2004; Esteban, 2004; Rosselló et al., 2005; Flores y Barroso, 2012; Jiménez et al., 2015a, 2016).
Santos Ávila (volume 02, issue 03, 2015). Emílio Sarde Neto's dissertation, "Karitian Cosmography: Territory, Education and Ethnic Identity in Rondônia" is not in any database besides the program in which it was produced, being quoted in a dissertation of the Federal University of Uberlândia, in the post- a degree in Geography, by Alex Cristiano de Souza, entitled "Work and education: Critique of the production of knowledge about education in the field of Geography, 2016. The work of Maria Isabel Alonso Alves, "Indigenous identities: a look at the undergraduate course in intercultural basic education in Rondônia" was not found in any other bank besides the origin program and was not mentioned in any available place. The same occurs with the work of Maria Aparecida Siqueira Santos, "Educational policies and their impacts on indigenous education: A study in the communities belonging to the municipality of Guajará Mirim / Ro" and Wanda Isabel Senatore Vargas Rodrigues, "the urban school and the inclusion of indigenous students: The Challenges of the Curriculum in Search of an Intercultural Dialogue ".
Abstract Planetary Health has been conceived as a new discipline focused on “the health of the human civilization and the health of the natural systems on which it depends”. The overwhelming evidence that we are surpassing the sustainable limits of global ecosystems pushed the World Health Organization of Family Doctors to recommend the introduction of Planetary Health in the core curriculum of medical schools. Despite the growing interest in this concept, its teaching faces many questions, most notably, the query around its sufficiency as an innovative and robust field to be formally introduced in academic health institutions. In order to start this investigation, we performed a scientometric analysis of the indexed articles from 1945 to 2016 about the keyword “Planetary Health” in the Web of Science (WoS) database. Only 50 registries were indexed. The first scientific publication of PH was in 1998, with a marked increase of publications in 2016. We discuss the growing literature on the term, the role of the collaboration between “The Lancet” and Rockefeller Foundation, the incipient networks, and its promising future. We conclude that we need more research and innovative collaboration about this emerging field of Planetary Health in order to establish it in the core disciplines of medicine and science.
The original research has been based on the study and experiments of Neural Network models in the spectral analysis of signals derived from stratigraphic records referred to mountain profiles. The target was the determination of periodicities induced by astronomical phenomena, like equinox precession, obliquity and eccentricity of the Earth polar axis, in the sedimentation process.
To characterize the SBAIT members most successful in publishing in trauma, the authors were separated accord- ing to: 1. the place (state) of residence at the time of the publication; 2. the number of publications; 3. year of gra- duation from medical School and 4. whether they had graduate studies overseas. The year of graduation and overseas training was obtained from the open publicaly available online web CV Plataforma Lattes (http://www. lattes.cnpq.br). Next we analyzed the association between years of graduation and number of publications, as well as whether overseas training resulted in sustained increase in scientificproduction. The papers published during the overseas training were not included in the present analysis. The statistical analysis used mean/median, standard deviation and maximum/minimum values for the numeric variables. The Spearman correlation was used to analyze the variation in the total number of publications, year of publication and Impact Factor. Linear regression analysis was used to estimate the association of the total number of publications, while the Mann-Whitney test was used to compare publications between the two study periods (before and after 2003). Due to the sample size and lack of normal distribution, the Kruskal-Wallis test was used to analyze time from graduation from medical School. Pear- son qui-square and the exact Fisher test were used for values below 5. Significance was determined to be of 5% (p<.05) and SAS for Windows was used (version 9.1.3. SAS Institute Inc, 2002-2003, Cary, NC, USA).
To this end, the field of Communication is analy- zed from a bibliometric perspective, applying different indicators that provide quantitative information. Other similar studies in this field have analyzed articles published in Spanish journals (Martínez-Nicolás, 2011); the different co-authorship typologies (Fernán - dez-Quijada, 2011); the theses produced on a specific topic (Repiso & al, 2011) or the particular features of Spanish journals (de Pablos & al, 2012). While there are some earlier studies which apply bibliometric tech- niques in their analysis, for instance, of the characteris- tics of production in the most relevant ISI journals (Castillo & al., 2012), or those of which carry out the study of a specific journal in detail (Roca, 2012), the recent inclusion of these three Spanish journals in the JCR means that no studies have been carried out on them thus far.
There are two varieties of rubber natural rubber and synthetic rubber. Natural rubber production is mainly involved in three major areas Malaysia, Thailand and Indonesia. In India, rubber production is at the rate of 6% per annum. Growing and processing natural rubber is considered to be one of the most complex agricultural industries. Natural rubber production combines botany, chemistry, and sophisticated machinery with dexterous skills of the people who harvest the trees.
authored scholarly material, but it does not take into consideration the content of those scholarly contributions. For this reason, I implement the aforementioned analysis of co- authorship activity with an investigation of the concepts utilized by researchers in their scholarly output. By connecting similar concepts available in the scholarly items, I construct a network linking related topics and knowledge constructs extracted from the bibliographic record, i.e. an epistemic network. I borrow this definition from early work in the field of qualitative bibliometrics by Callon et al. (1986) and Leydesdorff (1991) who construct networks describing associations between the many heterogeneous entities that lead to the construction of scientific facts into an array that is “strong and durable”. Closely analyzing a set of scientific texts, they build, for every analyzed scholarly article, an epistemic network composed of “powerful words” (keywords and other extracted key phrases). In section 4.3, I discuss how I build an epistemic network to represent manifestations of intellectual interactions within the context of CENS research.
