Bibliometric revision regarding the use of survival analysis in seed germination studies

Leer artículo

 

 

Studies on seed science are developed for a wide range of purposes, being the statistical analysis of data essential for experimental reliability and evidence. Due to the characteristics of seed data, several statistical methods can be applied, among them the survival analysis stands out, in virtue of allocating censored data and describing phenomena over time. Therefore, this bibliometric study verified the use of survival analysis in studies with seed germination and to examine the applications of survival analysis in original articles from the Web of Science database for the period from 2000 to 2020. For the application of survival analysis, there was a low number of publications related to seed science, with the USA being the country with the highest number of publications mainly to studies in plant ecology and physiology. In general, the researches were most involved to the evaluation of factors influencing dormancy, physiological stresses, dispersion capacity, population differences and habitats of development which affected seed germination. Therefore, the qualitative overview demonstrates that the survival analysis is a statistical tool of great potential regarding the studies in the area.

Leer artículo

 

 

This article aims to characterize the scientific production of Digital Educational Resources (DER) and Virtual Learning Objects (VLO) published between 2000 and 2021 and indexed in the main collections of Web of Science, Scielo Citation Index, Scopus, and Dimensions. To achieve this, a two-phase quantitative methodology is used. In the first phase, a bibliometric analysis (n=649) is carried out to characterize the production and, in the second phase, a content analysis (n=171) is carried out of publications focused on the development of DER and VLO. Our results show that Colombia is the country with the highest production of DER and VLO, that the largest number of educational resources are aimed at higher education students and that few are inclusive in their characteristics. Finally, the production of scientific texts has been increasing and is positioned as a trend in the specialized databases included in this study, especially for the time frame of the Covid-19 pandemic.

Leer artículo

 

 

Capital structure is one of the central themes of Corporate Finance. The development of theories and the range of empirical research on the behaviors and determinants of the capital structure are striking. Despite this interest in the subject, few studies have focused on the characteristics of this academic production, especially work on female participation. Thus, this study aims to analyze the female participation in academic production on capital structure in Brazilian periodicals. The collection of the articles of the sample was done through Portal Periodicos/Capes, SciELO and SPELL databases. The non-probabilistic sample, obtained from the search in the databases, comprised 195 articles, written by 412 authors from 97 different institutions, published by 66 journals. Through the bibliometric analysis, it was observed that the female participation is smaller than the male participation. The main findings identified that only 29% of the authorship of the articles belonged to women; that historically female participation is lower than male participation; that authors prefer to produce their articles in partnership and the more authors there are in an article, the greater the presence of women in that article; the highest titers had a smaller contingent of women; of the most productive authors, only three are women; female participation was higher than male participation in only two of the 11 most representative institutions.

Work ability and functional aging: a Systemic Analysis of the Literature using ProkNow-C (Knowledge Development Process – Constructivist)

Leer artículo

 

 

Brazilian Institute of Geography and Statistics (IBGE) data indicate that the elderly population of Brazil numbering 11% in 2003, will attain 33.7% by 2060. This aging process can be diagnosed from the capability workers possess for their labor activities. ProKnow-C was used to conduct the review, carrying out bibliometric and systemic analysis of the literature on the subject. The results led to the compilation of a portfolio with 29 papers, highlighting the most relevant journals, authors and keywords. Systemic analysis provided important results: survey methodology was applied on 26 papers, 21 of which were cross-sectional studies; in all the papers the WAI was associated with sociodemographic data; in 10 studies it was found that the work ability decreased while age increased and the practice of physical exercises was positively associated with the WAI in 11 studies. The results led to the perception that the WAI is an instrument that makes it possible to diagnose the situation of the working life of employees, and, in the case of low rates, the presence of early functional aging is detected. The study highlighted the importance of assessing aspects of the worker’s social life, since these factors influence the work ability positively or negatively.

Leer artículo

 

 

Temporomandibular disorder (TMD) is an umbrella term used to describe various conditions that affect temporomandibular joints, masticatory muscles, and associated structures. Although the most conservative and least invasive treatment is preferable, more invasive therapies should be employed to refractory patients. Tissue engineering has been presented as a promising therapy. Our study aimed to investigate trends and point out future research directions on TMD and stem cells. A comprehensive search was carried out in the Web of Science Core Collection (WoS-CC) in October 2022. The bibliometric parameters were analyzed through descriptive statistics and graphical mapping. Thus, 125 papers, published between 1992 and 2022 in 65 journals, were selected. The period with the highest number of publications and citations was between 2012 and 2022. China has produced the most publications on the subject. The most frequently used keywords were “cartilage”, “temporomandibular joint”, “mesenchymal stem cells”, and “osteoarthritis”. Moreover, the primary type of study was in vivo. It was noticed that using stem cells to improve temporomandibular joint repair and regeneration is a significant subject of investigation. Nonetheless, a greater understanding of the biological interaction and the benefits of using these cells in patients with TMD is required.
