Phase Change Slurries for Cooling and Storage: An Overview of Research Trends and Gaps

Leer artículo

 

 

Phase change slurries (PCSs) have great potential as both a heat transfer fluid and an energy storage medium for cooling processes, cold energy storage, and cold energy transportation due to desirable thermophysical properties. One of the major benefits of PCSs compared to pure phase change materials is their fluidity, thus making them cooled or heated by a heat exchanger, pumped through pipes, discharged, and stored directly in a thermal energy storage tank. The use of encapsulated phase change slurries and gas hydrate slurry has thus attracted considerable interest as reflected in the literature with a rising number of publications and institutions involved in the area. The use of bibliometric techniques has found a recent interest in the literature to define the progress of different scientific topics and inspire researchers to identify novelties. In this paper, bibliometric analysis and a detailed systematic review are carried out to show the state-of-the-art development of PCSs for cooling applications. Research gaps and hotspots are identified to help define future perspectives on this topic.

ASSISTIVE TECHNOLOGIES: RESOURCES FOR VISUALLY AND HEARING IMPAIRED PEOPLE

Leer artículo

 

 

In Brazil, there are still barriers that prevent the accessibility of people with disabilities in education, and Information and Communication Technologies (ICT) can be used as a means of expanding new possibilities for organizing the teaching and learning process. Most of these barriers stem from the lack of technological resources, non-compliance with current legislation, and the way society organizes itself, ignoring the diverse demands of its population. In this context, this article aims to identify the assistive technologies that have been used by people with disabilities. Therefore, the study is based on a methodology of an exploratory nature and a qualitative approach, conducted from a bibliometric research. The results show the existence of assistive technologies that aim to contribute to the accessibility of students with visual and hearing impairments in education, and that can help teachers in pedagogical practices.

Corporate governance, performance and crisis: a systematic review of the literature

Leer artículo

 

 

This study aims to review, systematically, the literature that relates corporate governance with company performance in periods of economic crisis. For this purpose, through the bibliometric analysis, a sample of 755 articles extracted from the web of science and elsevier scopus databases were analyzed. The ten most relevant documents in terms of citation were analyzed in a qualitative manner. As results, it was observed that the economies developed concentrate the publications, as well as they are object of study in a great part of the articles. In addition, few studies explore a sample involving companies from under-developed or developing countries. Therefore, there is a need for studies that have as research objects developing economy companies and that consider the specific economic, social and environmental characteristics of these regions.

A decade of Ecuador ‘ s efforts to raise its health research output: a bibliometric analysis

Leer artículo

 

 

Background: Over the past decade, the political movement called ‘Revolucion Ciudadana’ implemented a variety of policies and interventions (P&I) in Ecuador to improve higher education and strengthen local research capacity. We refer specifically to the ‘Mandato 14’ and the Higher Education Law (LOES, Spanish acronym) launched in 2008 and 2010, respectively. Objective: To assess the impact of these P&I (Mandato 14/LOES) on the production of health sciences-related articles (HSRA), and the relationship of these HSRA with the country’s health priorities. Methods: A Scopus search was performed to retrieve HSRA published from 1999 to 2017. Bivariate analysis was used to assess variation between the period I (1999-2008) and period II (2009-2017). Further, we examined the association between the top 10 causes of mortality and the total HSRA output. Results: The final study sample consisted of 2784 articles. After 2008, Ecuadorian production of HSRA increased steadily from 671 to 2133 publications (p<.001). Overall (1999-2017), the most common study design was cross-sectional (32.3%), the primary research focus was in the clinical-surgical area (49.3%), and the academic institutions were the primary drivers of scientific production during period II (56.9% vs. 29.5%, p<.001). Further, we found a decrease in the production of randomized controlled trials (6.7% vs. 1.8%, p.05). Conclusions: Ecuadorian HSRA output increased significantly after 2008. This larger volume of scientific output could be the result to the Mandato 14/LOES implemented in the last decade. However, a low percentage of HSRA are dedicated to addressing the country’s health priorities. Proper planning, execution and monitoring of national health research agendas would reduce the mismatch between health burden and the HSRA output in Ecuador and other low-and middle-income countries.

Project management in the public context: research field mapping

Leer artículo

 

 

The advent of New Public Management introduced the concept of project management until then exclusive to the private sector, paving the way for increased state efficiency. In this scenario, this article aims to locate, synthesize, and identify the theoretical proximity among studies on project management in the public context. The bibliometric methodological approach used relational analysis of citations and the methods of cocitation and coupling to reveal the connections among the studies published. Exploratory factor analysis of cocitation and coupling led to six factors, indicating the intellectual structure, and enabling the generation of a factor integration framework from the most frequent citations. The results indicated the prevalence of studies on project management and e-government competencies. It also amplifies discussions with the presentation of an agenda directed explicitly to the management of public projects.

The impact of scientific production and its relationship with environmental performance

Leer artículo

 

 

The objective of this work is to study the relationship between the production of indexed documents in the area of environmental sciences in the SCOPUS database and the best evaluated countries within the Environmental Per-formance Index (EPI). To do this, the first three places in the EPI for the years 2014, 2016 and 2018, and three Latin American countries, Brazil, Costa Rica and Mexico are analyzed by bibliometric methods. Among the applied analyzes, a thematic categorization was carried out using the keywords of the environmental science production using the axes of the EPI as an identification variable, statistical comparison regarding the scientific production of each country and the type of access to it. It was found that countries with strong governance (countries better evaluated within the index) are not related to a greater production of environmental science publications.

Sustainable urban drainage: delineation of a scientific domain of knowledge production

Leer artículo

 

 

Sustainable Urban Drainage emerged and gained prominence during the late 90s. Despite this progress, there is little uniformity in subjects and definition of terms within the overall sustainability theme. This tends to create a duplication of objectives and confusion about the correct use of techniques and procedures. This paper seeks to identify, map and evaluate ‘Sustainable Urban Drainage’ as a scientific domain, using relationships between underlying subthemes. We analyzed 3,805 publications by 8,237 authors with relation to 11,957 citations using sociometric and bibliometric techniques. The results confirm the existence of the knowledge domain with one main nucleus and 20 independent networks. Core subthemes such as stormwater management, low impact development, integrated urban water management, bioretention, and best management practices are distinguishable as the main domain.
