title: Russian Learner Corpora Research: State of the Art and Call for Action

description: ABSTRACT With the increase in availability and user-friendliness of Russian language corpora and corpus-analytic tools, the field of Russian language education has recently begun to employ corpus linguistics as an approach to understanding the dynamic of language development in users of Russian as a second and heritage language. The paper provides a brief overview of the current state of learner corpus research as a field and explores the benefits of application of corpus linguistics methods and instruments to the study of Russian. The paper reviews pertinent issues in corpora design, compilation, and annotation; offers an overview of the existing Russian language corpora and reports on the currently available corpus-based studies of Russian as a second/heritage language. The paper concludes with a call to the field to explore the benefit of corpus-based approaches to the study of Russian.

title: Impact of the COVID-19 pandemic on the epidemiology of traffic accidents: a cross-sectional study

description: ABSTRACT Objective: to assess the epidemiological profile of traffic accident victims in the setting of the Coronavirus Disease 2019 (COVID-19) pandemic and analyze the admissions throughout the different levels of restriction (flags), as well as compare the results with the pre-pandemic period. Methods: a cross-sectional study was performed, with probability sampling, in a trauma center in Brazil. Medical records of patients involved in traffic accidents from June 2020 to May 2021 were evaluated. Aside from epidemiological characteristics, variables such as the current flag, the trauma mechanism, the resulting injuries, and the Revised Trauma Score (RTS) were also considered. Data were compared between three different flag periods and the proportion of consultations during the pandemic was compared with that from pre-pandemic time (December 2016 to February 2018). Results: it was observed that 62.2% of the patients were victims of motorcycle accidents, 77.5% were male, and the mean age was 33 ± 12.4 years. The mean and median RTS were 7.5 and 7.8, respectively. Statistical difference was stated when comparing the number of visits per day between the yellow and red flags (p=0.001) and orange and red flags (p=0.016). A significantly lower number of consultations for traffic accidents was observed in the pandemic when compared to the pre-pandemic period. Conclusions: the epidemiological profile of the study consisted mostly of young men who were victims of motorcycle accidents. There was a lower incidence of admissions during red flag periods and a lower proportion of consultations throughout the survey when compared to the pre-pandemic period.

title: Immunohistochemical expression of Drosha is reduced in eutopic and ectopic endometrium of women with adenomyosis

description: The objective of this study was to evaluate the immunohistochemical expression of Dicer, Drosha, and Exportin-5 in the eutopic and ectopic endometrium of women with adenomyosis. Twenty-two paired ectopic and eutopic endometrium from women with adenomyosis and 10 eutopic endometrium samples from control women undergoing hysterectomy were included in the study. Paraffin-embedded tissue blocks were cut and stained for immunohistochemistry. The percentage of epithelial cells positively marked was identified digitally after an automated slide scanning process. Mann-Whitney test or Wilcoxon signed-rank test was performed for independent and paired groups, respectively. A lower expression of Drosha was observed in the eutopic endometrium of women with adenomyosis than in the eutopic endometrium of women without the disease (69.9±3.4% vs 85.2±2.9%, respectively) (P=0.016; 95%CI: 3.4 to 27.4%). We also detected lower Drosha expression in the ectopic endometrium of women with adenomyosis than in the eutopic endometrium of the same women (59.6±3.2% vs 69.9±3.4%, respectively) (P=0.004; 95%CI: 2.3 to 16.7%). Additionally, we observed a correlation between Drosha expression in the ectopic and paired eutopic endometrium (P=0.034, rho=0.454). No significant difference in Dicer or Exportin expression was observed. Predominant pattern of cytoplasmic staining for the anti-Drosha antibody and both a nuclear and cytoplasmic pattern for the anti-Exportin antibody were observed. Drosha expression was significantly lower in the endometrium of women with adenomyosis compared to the eutopic endometrium of asymptomatic women without the disease. Furthermore, its expression was lower in the ectopic endometrium but correlated to the paired eutopic endometrium.

title: Partially-conformal variations of the Standard Molodensky datum transformation

description: Abstract: Standard Molodensky is a recognised method of transforming coordinates between geodetic datums. Although less accurate than some other methods, it has the merit of being direct. That is to say it can be applied to geodetic coordinates, without involving Cartesian coordinates that give rise to difficulties in computing latitude. This paper considers the use of Standard Molodensky when at least one of the datums is 2D+1D in nature, meaning that that horizontal and vertical positions are obtained by different methods. This was generally the case before 3D positioning by satellites and is a widespread characteristic of local datums that are still used. The 2D+1D property weakens the argument for 3D conformality, and invites the possibility that different translation parameters might be used for horizontal and vertical shifts. The possibility of including a Z-rotation as a 7th parameter is also considered. Besides being ideal for those who favour the simplicity of Standard Molodensky, the variations introduced in this paper offer significant improvements in accuracy such as error reductions of 75%, 69% and 99% in the three selected case studies.

title: Do Investments in Innovation and Quality Management Systems Ensure Superior Financial Performance? A Quantitative Study of Brazilian Publicly Traded Companies

description: ABSTRACT Investments in innovation and quality management systems have long been presented as tools that can boost organizational performance. In Brazil, empirical, systematic, and rigorous research on such relations on such relations is still scarce. Given this context, this study sought to verify, using multiple linear regressions, how investments in innovation, and adoption of the six sigma methodology and ISO 9001 certification, impacted the financial performance, in terms of profitability, of the 101 Brazilian publicly traded companies comprising the study sample in fiscal year 2019. Regression results shows evidence that Brazilian publicly traded companies are having little success in regards to financial results by their six sigma efforts, and that R&D efforts and ISO 9001 certification exert positive and significant impact on profitability, via the ROA index. The interaction between ISO 9001 and R&D came close to significance, indicating a possible synergistic effect to be tested in future studies. Besides contributions to the entrepreneurial field, aiding companies to direct their efforts toward initiatives capable of positively impacting profitability, such findings also help advance academic knowledge.

title: Airline’s business performance indicators and their impact on operational efficiency

description: Abstract Airlines must constantly evaluate the costs and efficiency of their operational performance indicators to establish a competitive business market strategy. This study aims to investigate the relevance of some performance indicators of airline´s management and operational efficiency. With the use of a panel data regression for the four largest private Brazilian airlines - Avianca, Azul, Gol, and Latam, from 2009 to 2017, the results show that operational efficiency is achieved when there is a greater offer of routes and flight frequency to meet passenger demand, generating higher revenue passenger kilometer (RPK). On the other hand, shorter stage length and reduced takeoff numbers affect inversely proportional the operating efficiency as a function of fuel consumption and energy capacity. Through the analysis of these performance indicators, it is possible to determine strategies that support decision making to increase the operational efficiency of airlines.

title: Ultrashort anisoperistaltic end-to-side ureteroureterostomy in renal transplantation

description: ABSTRACT The improvement of surgical techniques in kidney transplantation aims to reduce the incidence of post-transplant complications, contributing to the reduction of hospital stay, related costs, morbidity and mortality, in addition to improving the quality of life of patients. The choice of the best technique is influenced by several factors and the most common technique for urinary tract reconstruction in transplants is performed with implantation of the ureter of the graft in the caudal position, with the anastomosis performed in the bladder. However, the kidney pole can be inverted and the graft ureter anastomosis can be performed directly on the recipient’s ureter, facilitating venous and ureteral anastomoses and reducing urological complications.
