Abstract Objective: To describe the combustion process of sugarcane RAC with CO2 capture by manganese-based oxygen transporters during the period 2015-2021. Design: Bibliometric observational study. Location: Combustion of cutting waste with CO2 capture by manganese-based oxygen conveyors.Main measures: Magazine, year of publication, first/last author, workplace and autonomous community were obtained in each register. Subsequently, the articles were classified according to their content or research area. The impact factor was obtained from the bibliometric analysis base of Scopus and Vos viewer.Results: Through the search criteria used, 475 documents were recovered in the 2015-2021 semester, excluding 2637 because they did not correspond to affiliation to centers or institutions directly related to documents related to chemical combustion and CO2 capture. In total, 73 documents were selected, in which an increase and interest in the study of these processes was verified both in the research areas and in the journals in which they are published. Most of the studies have been published in universities or research centers and differences were observed in terms of the volume of international and national scientific production, so it is necessary to increase these investigations in the country of Colombia.

Among higher education students, perceived employability gained eminence in the last decades that attracted scholarly interests. Researchers theoretically and empirically studied the perceived employability though; inadequate preliminary review studies exist on this topic. Available researches mostly concentrated on a single approach. Thus, this study carried out a comprehensive review that comprised a systematic literature review (SLR) and bibliometric analysis that might boost understandings in the body of the literature. In the research process, the Scopus database from the 2008 to 2021 periods was used. The researchers set the search criteria that allowed the inclusion of 59 papers published in 45 peer-reviewed international journals. The paramount influential papers and prolific authors formulated the unit of this analysis. Furthermore, for the identification of thematic clusters and creating network maps, VOS viewer software was deployed. Citation analysis, co-authorship analysis, co-citation analysis, and co-occurrence of keywords analysis have generated interesting patterns which articulate the study results. The findings revealed enlightening insights on the content and characteristics of perceived employability, publication trends, highly cited papers, productive authors, contributing countries, repetitive themes, productive journals, and also unveiled gaps providing avenues for upcoming research works.

The high level of energy consumption of buildings is significantly influencing occupant behavior changes towards improved energy efficiency. This paper introduces a systematic literature review with two objectives: to understand the more relevant factors affecting energy consumption of buildings and to find the best intelligent computing (IC) methods capable of classifying and predicting energy consumption of different types of buildings. Adopting the PRISMA method, the paper analyzed 822 manuscripts from 2013 to 2020 and focused on 106, based on title and abstract screening and on manuscripts with experiments. A text mining process and a bibliometric map tool (VOS viewer) were adopted to find the most used terms and their relationships, in the energy and IC domains. Our approach shows that the terms “consumption,” “residential,” and “electricity” are the more relevant terms in the energy domain, in terms of the ratio of important terms (TITs), whereas “cluster” is the more commonly used term in the IC domain. The paper also shows that there are strong relations between “Residential Energy Consumption” and “Electricity Consumption,” “Heating” and “Climate. Finally, we checked and analyzed 41 manuscripts in detail, summarized their major contributions, and identified several research gaps that provide hints for further research.

This paper presents a bibliometric analysis of relevant publications in the field of behavioral finance and behavioral accounting. The analysis shows that the emerging themes of research in recent years in behavioral finance is on investors’ sentiment, social media, investors’ attention, and financial literacy. In the field of behavioral accounting, biases such as  overconfidence, framing effects or cognitive constraints on information processing, have been explored in greater detail. Other than cognitive biases, this field includes studies such as behavioral tax, organizational ecology, and performance evaluative style of organization, among others. Interestingly, our analysis suggests that research in behavioral accounting is comparatively underdeveloped than research in behavioral finance. This bibliometric analysis has been extended by network analysis using, “Visualization of similarities, (VOS) viewer” software. Using the themes generated here the direction for future scope of research work has been discussed.
