Some bacteria and protozoan species are important pathogens causing high mortality rates not only in humans, but also in other mammal species including bats. Infectious agents, such as viruses, bacteria, protozoa, and fungi have been reported in the order Chiroptera, but a thorough analysis of zoonotic unicellular pathogens is needed. To address this topic, we conducted an exhaustive search of literature reports on pathogenic bacterial and protozoan infections in bats, in order to summarize the current state of knowledge on these pathogens. From this search, we obtained information on seven protozoan and 12 bacterial species present in 187 bat species, which were retrieved from 169 articles. Despite all the records, bats are only considered reservoirs for two protozoan species. Thus, more studies are needed to consider bats as reservoirs for bacteria. At North American Society for Bat Research (NASBR) symposia, 17 studies have been presented and discussed, but only two focused on pathogens responsible for the principal causes of death in human populations. More worldwide studies are needed to assess the actual role of bats in public health problems and to help develop conservation measures for bat populations that need to be protected.

The main objective of this research is to design an Organizational Culture Transformation Model (OCTM) prototype, in order to enable a High Performance Organization (HPO).There are three main processes involved in the methodology. Two of them, the definition of the main OCTM work elements as an initial hypothesis based on a work environment approach and the scientific visualization of the key Organizational Culture research hubs through the analysis of the main topics in research publications, flow in parallel. Subsequently, at a certain point, both of these merge in a third process, the OCTM prototype definition. This last process, will deliver the Organizational Culture Transformation Model prototype, which essentially constitutes the main objective of the study. As result of the methodology, an Organizational Culture Transformation Model prototype has been developed. The resulting model will serve as a reference framework for those companies that wish to conduct an in-depth re-structuring of their operations, focusing it on their human capital.

Environmental concerns, such as global warming and scarcity of natural resources, pressure companies to develop and adopt cleaner technologies and production processes. Besides, the search for sustainable development (as recommended by Agenda 2030 from the United Nations) has made companies rethink their whole supply chain, including transport activities. Besides, governments have been proposing public policies to obtain positive impacts in the economic, social and environmental dimensions. In this context, many studies have pointed out that electric mobility is a sustainable alternative to the transport sector and, in many EU countries, the government has bet on subsidies to attract manufacturers and customers to this market. Therefore, this paper aims to identify the role of electric vehicles (EV) in sustainable supply chains, considering the articles published in the Web of Science (WoS) database. We realize that there is a low quantity of papers dedicated to investigating the EV in this context. Many papers claim to perform sustainable analysis but do not evaluate the triple bottom line’s three dimensions. Nevertheless, we identified that governments had developed policies to incentivize the introduction of electric vehicles in the market.

The aim of this study is to show the extent to which different models of leadership in education are studied, including changes in the trends of research on each model over time, the most prominent scholars working on each model, and the countries in which the articles are based. The analysis of related literature was first conducted using a bibliometric analysis of research and review papers indexed in the Science Database Web between 1980 and 2014. A more in-depth analysis of the selected papers was then carried out using the content analysis method. Results have shown that there has been an increasing interest in educational research leadership models over time. Distributed leadership, educational leadership, teacher leadership and transformational leadership are the most studied leadership models in education research. It was also found that related research increasingly focuses on the impact of leaders on organizational behaviors/conditions and student achievement. As a result, the use of quantitative methodology has increased significantly over the last decade. Possible reasons for such changes, implications and recommendations for future research are also discussed.

Chitosan has attracted increasing attention from researchers in the pharmaceutical and biomedical fields as a potential agent for the prevention and treatment of infectious diseases. However, identifying the development of emerging technologies related to this biopolymer is difficult, especially for newcomers trying to understand the research streams. In this work, we designed and implemented a research process based on a bibliometric predictive intelligence model. Our aim is to glean detailed scientific and technological trends through an analysis of publications that include certain word phrases and related research areas. Cross correlation, factor mapping, and the calculation of “emergent” scores were also used. A total of 1,612 scientific papers on chitosan technology related to viral disease treatment published between 2010 and 2020 were retrieved from the Web of Science. Results from the keyword modelling quantitatively highlight three major frontier research and development topic groups: drug delivery and adjuvants, vaccines and immune response, and tissue engineering. More specifically, the emergent scores show that much of the chitosan-based treatment for viral diseases is in the in vitro stage of development. Most chitosan applications are in pharmacology/pharmacy and immunology. All results were confirmed by experts in the field, which indicates that the validated process can be applied to other fields of interest.

We describe a characterization of the conceptual and emotional changes on environmental issues in a sample of firms certified under the ISO 14001 standard. Business communications regarding the main Spanish industrial firms have been downloaded from the ABI/INFORM database and processed using Vantage Point software, in order to study the evolution of the main concepts and emotions before and after the certification year. Our study concludes that in the years before certification environmental management was fundamentally tied to operative issues, broadly pivoting on the immediate impact of a firm’s productive activities. Environmental management gains strategic traction in the years after certification, positioning itself near corporate decision-making concepts and associated with adjectives that denote relevance and positivity. The sentiment analysis points at an increased positivity of environment-related issues, accompanied by a general decrease in negative emotions and an increased presence of expectation and planning emotions.

The COVID-19 pandemic presented a challenge to the global research community as scientists rushed to find solutions to the devastating crisis. Drawing expectations from resilience theory, this paper explores how the trajectory of and research community around the coronavirus research was affected by the COVID-19 pandemic. Characterizing epistemic clusters and pathways of knowledge through extracting terms featured in articles in early COVID-19 research, combined with evolutionary pathways and statistical analysis, the results reveal that the pandemic disrupted existing lines of coronavirus research to a large degree. While some communities of coronavirus research are similar pre- and during COVID-19, topics themselves change significantly and there is less cohesion amongst early COVID19 research compared to that before the pandemic. We find that some lines of research revert to basic research pursued almost a decade earlier, whilst others pursue brand new trajectories. The epidemiology topic is the most resilient among the many subjects related to COVID-19 research. Chinese researchers in particular appear to be driving more novel research approaches in the early months of the pandemic. The findings raise questions about whether shifts are advantageous for global scientific progress, and whether the research community will return to the original equilibrium or reorganize into a different knowledge configuration.

As a global pandemic threatens health and livelihoods, finding effective treatments has become a vital issue that requires worldwide collaboration. This study examines research collaboration and network profiles through a case study of coronavirus diseases, including both the extinct severe acute respiratory syndrome coronavirus (SARS-CoV) and the emerging species (SARS-CoV-2). A scientometric process was designed to apply quantitative tools and a qualitative approach employing technological expertise to accomplish a three-level collaboration analysis. The text mining software, VantagePoint, was used to analyze research articles from the Web of Science database to identify the key national, organizational, and individual players in the coronavirus research field combined with indicators, namely, the breadth and depth of collaboration. The results show that China and the United States are at the center of coronavirus research networks at all three levels, including many endeavors involving single or joint entities. This study demonstrates how governments, public sectors, and private sectors, such as the pharmaceutical industry, can use scientometric analysis to gain insight into the holistic research trends and networks of players in this field, leading to the formulation of strategies to strengthen research and development programs. Furthermore, this approach can be utilized as a visualization and decision support tool for further policy planning, identification and execution of collaboration, and research exchange opportunities. This scientometric process should be directly applicable to other fields.

This article aims to map the scientific production concerning the inclusion of people with disabilities in Science Education to promote a reflection on the production of this area. Bibliometric analysis is used to help understand what stage of research a particular subject is at. Publications on the topic indexed at the Web of Science Core Collection (WoS) were evaluated. A total of 119 articles published between 2009 and July 2019 were selected as dealing specifically with the subject. An increase in the number of articles associating Science teaching (ST) and Inclusive Education (IE) was noted. The journals that published the most, the most productive authors in the area and their collaboration networks were identified. A content analysis of the research was also carried out and the main investigated topics were pointed out. Educational levels, types of disabilities, central themes and specific science areas prevailing in the mapped research were also indicated. We conclude that, despite the growing number of articles, scientific production associating SE and IE is still small, concentrated, and not shared with the scientific community through scientific education journals, and that most research is focused on the use of methodologies and resources, and not on their development.

The COVID-19 pandemic presents a great public health challenge worldwide, especially given the urgent need to identify effective drugs and develop a vaccine in a short period of time. Globally, several drugs and vaccine candidates are in clinical trials. However, because these drugs and vaccines are still being tested, there is still no definition of which ones will succeed.This study aimed to assess the opinions of over 1000 virus researchers with knowledge on the prevention and treatment of coronavirus-related human diseases to determine the most promising drug and vaccine candidates to address COVID-19. We mapped the clinical trials related to COVID-19 registered at ClinicalTrials.gov. These data were used to prepare a survey questionnaire about treatments and vaccine candidates for COVID-19. In May 2020, a global survey was conducted with authors of recent scientific publications indexed in the Web of Science Core Collection related to viruses, severe acute respiratory syndrome coronavirus, coronaviruses, and COVID-19. Remdesivir, immunoglobulin from cured patients, and plasma were considered to be the most promising treatments in May 2020, while ChAdOx1 and mRNA-1273 were considered to be the most promising vaccine candidates. Almost two-thirds of the respondents (766/1219, 62.8%) believed that vaccines for COVID-19 were likely to be available in the next 18 months. Slightly fewer than 25% (289/1219, 23.7%) believed that a vaccine was feasible, but probably not within 18 months. The issues addressed in this study are constantly evolving; therefore, the current state of knowledge has changed since the survey was conducted. However, for several months after the survey, the respondents’ expectations were in line with recent results related to treatments and vaccine candidates for COVID-19.
