“DIGA-ME QUANTOS TE CITAM, E EU TE DIREI QUEM ÉS”: ESTUDO SOBRE AS CITAÇÕES NO ÂMBITO DA PESQUISA CONTÁBIL BRASILEIRA
Authors: Vieira Soares Sandro , Pereira de Castro Casa Nova Silvia , Nonato Lima Filho Raimundo
Published: April 2021

Uma perspectiva teórica afirma que os diversos motivos para que artigos sejam citados transitam entre dois polos denominados universalista e social-construtivista. Características, como originalidade dos resultados e rigor metodológico, são classificadas como fatores do polo universalista; enquanto características, como fama do autor e prestígio do periódico, são classificadas como do polo social-construtivista. Diante dessa perspectiva teórica, coloca-se a questão de pesquisa: quais fatores do polo social-construtivista influenciam as citações que um artigo sobre Contabilidade recebe no âmbito da pesquisa contábil brasileira? Para responder essa questão, fez-se uma coleta de dados de 2.540 artigos, publicados por revistas brasileiras de contabilidade, entre os anos de 2007 e 2012, realizando-se, para a análise desses dados, uma regressão binomial negativa. Com base na revisão de literatura, foram elaboradas 16 hipóteses de fatores que influenciam a quantidade de citações dos artigos. As hipóteses sobre a influência dos fatores afiliação institucional do primeiro autor, revista em que foi publicado, linha de pesquisa e número de referências foram aceitas. Conclui-se, portanto, que, no âmbito da pesquisa contábil brasileira, as citações recebidas por um artigo sofrem influência da afiliação institucional do primeiro autor, da revista em que o artigo foi publicado, da linha de pesquisa a que pertence e do número de referências, ou seja, fatores relacionados ao polo social-construtivista. A aceitação apenas parcial e a rejeição das demais hipóteses revelam que o cenário da pesquisa contábil brasileira se mostra flexível quando comparado ao cenário de pesquisa internacional.

Published: April 2021

Deep learning has achieved a great success in face recognition (FR), however, little work has been done to apply deep learning for face photo-sketch recognition. This paper proposes an adaptive scale local binary pattern extraction method for optical face features. The extracted features are classified by Gaussian process. The most authoritative optical face test set LFW is used to train the trained model. Test, the test accuracy is 98.7%. Finally, the face features extracted by this method and the face features extracted from the convolutional neural network method are adapted to sketch faces through transfer learning, and the results of the adaptation are compared and analyzed. Finally, the paper tested the open-source sketch face data set CUHK Face Sketch database(CUFS) using the multimedia experiment of the Chinese University of Hong Kong. The test result was 97.4%. The result was compared with the test results of traditional sketch face recognition methods. It was found that the method recognized High efficiency, it is worth promoting.

Are Auditors' Reliance on Conclusions from Data Analytics Impacted by Different Data Analytic Inputs?
Authors: Koreff Jared
Published: April 2021

Global stakeholders have expressed interest in increasing the use of data analytics throughout the audit process. While data analytics offer great promise in identifying audit-relevant information, auditors may not uniformly incorporate this information into their decision making. This study examines whether conclusions from two data analytic inputs, the type of data analytical model (anomaly versus predictive) and type of data analyzed (financial versus nonfinancial), result in different auditors' decisions. Findings suggest that conclusions from data analytical models and data analyzed jointly impact budgeted audit hours. Specifically, when financial data are analyzed, auditors increase budgeted audit hours more when predictive models are used than when anomaly models are used. The opposite occurs when nonfinancial data are analyzed; auditors increase budgeted audit hours more when anomaly models are used compared to predictive models. These findings provide initial evidence that data analytics with different inputs do not uniformly impact auditors' judgments.

Published: April 2021

The relationship between the gut microbiota and chronic insomnia remains understudied. The aim of this paper was to investigate changes in the taxonomic composition of the gut microbiota and their associations with the levels of cortisol, melatonin and IL6 in patients with chronic insomnia. Our comparative prospective cross-sectional study enrolled 55 patients with chronic insomnia, who formed the main group (female patients: 58.2%, male patients: 41.8%; mean age 31.6 ± 7.4 years), and 50 healthy volunteers, who comprised the control group (females: 68.0%, males: 32.0%; mean age 33.2 ± 6.6 years). The taxonomic composition of the gut microbiota was profiled using 16S rRNA gene sequencing. Plasma cortisol and IL 6 and urine melatonin were measured by means of ELISA. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). In patients with chronic insomnia, the abundance of Faecalibacterium (p = 0.048), Prevotella 9 (p < 0.001) and Lachnospira (p = 0.036) was lower, whereas the abundance of Blautia (p = 0.012) and Eubacteriumhallii (p = 0.003) was higher than in healthy volunteers. Significant correlations were established between the levels of IL6 and the abundance of Faecalibacterium (r = –0.44; p = 0.001) and Blautia (r = 0.42; p < 0.001), as well as between cortisol concentrations and the abundance of Lachnospira (r = –0.41; p = 0.048). The abundance of Faecalibacterium and Blautiaс was correlated with higher PSQI (r = –0.47, p = 0.001; r = 0.45, p < 0.001, respectively). Our study contributed to the pool of data about changes in the gut microbiota and their associations with some endocrine and inflammation markers in patients with chronic insomnia. These data can be exploited to propose new strategies for the diagnosis and personalized treatment of insomnia aimed at normalizing the patient’s gut microbiota.
Sonographic features of ovarian tumors in pregnant women before surgical intervention and chemotherapy
Authors: Gerasimova AA , Klimenko PA
Published: April 2021

The problem of ovarian tumor differential diagnosis is solved using comprehensive ultrasound examination at different levels of efficiency. However, ultrasound imaging is an operator-dependent technique due to subjective interpretation of results. The study was aimed to assess the ultrasound signs of benign and malignant ovarian germ cell tumors (OGCTs) in pregnant women in order to determine the feasibility of surgical treatment and chemotherapy. The study was carried out using the logistic regression models. A group of 199 pregnant women with benign and malignant OGCTs were enrolled. Of them, 183 patients had benign, and nine patients had malignant tumors. In order to assess menstrual function and fertility, seven pregnant women were enrolled, who had previously received treatment for malignant OGCTs. Pre-operative assessment results were compared with morphological assessment data. Organ-preserving surgical treatment was performed (unilateral adnexectomy); if necessary, the patients received cisplatin-based chemotherapy. Perinatal outcomes were assessed. The median observation time between the malignant OGCT detection and the end of the study was 66 months (12–240 months). It was found that comprehensive ultrasound examination and logistic regression models (sensitivity 100%, specificity 92.3%, overall accuracy 92.8%) enabled differential diagnosis of benign and malignant OGCTs. The number of unnecessary surgical procedures in patients with benign OGCTs was been limited, the pregnancy and childbirth outcomes were improved. Nine pregnant women received organ-preserving surgical treatment for malignant OGCTs, and three patients received chemotherapy after surgery, which allowed the patients to realize their reproductive potential.

Published: April 2021

Distance learning (DL) changed the work-rest balance of teachers, increased risks of deterioration of their health and emotional burnout (EB). This study aimed to investigate the prevalence of risk factors affecting health and emotional state of teachers engaged in DL, as well as subjective assessment of the significance of these factors by teachers. We have surveyed teachers during traditional, in-person learning (TL) period (n = 224) and DL (n = 619), and took anthropometric measurements of 45 teachers during TL and 72 teachers when DL ended. EB was studied in 72 teachers with the help of V.V. Boyko questionnaire. Statistical processing was enabled by the Statistica 13 PL package, Student's t-test, χ2 test; to identify the relationship between indicators, we relied on regression analysis, effect occurrence probability calculation. Less than half of teachers are aware of the health risk factors (low level of physical activity — 36.1%, poor nutrition — 29.2%, lack of knowledge on disease prevention — 6.9%). After DL ended, only 30% of teachers considered themselves healthy; 13.1% reported lack of EB symptoms. An increase in the average body mass index value was established. Teachers underestimating EB and health risk factors were 2.3 times more likely to grow obese (OR = 0.40; 95% CI = 0.22–0.70). The study highlights high hygienic value of physical activity as a controllable health risk factor. Raising teachers' awareness of health preservation practices will help prevent deterioration of their health, development of EB and increase the efficiency of their professional activity.

Published: April 2021

This paper focuses on the similarity of functions between Trademarks and Limited Liability Company Name, namely quality assurance function, which enables both to provide a guarantee on the reputation of goods and/or services offered to the consumer. Such similarity of functions between those two different legal terminology opens a loophole for any party, based on bad faith, to conduct passing off towards a registered trademarks owned by another party through the use of a limited liability company name. This paper shows the urgency of a harmonization and integration between the mechanism of applying for Trademark registration and the submission of the name of a limited liability company in Indonesia. Therefore, this paper will examine and criticize the laws and regulations relating to the two terminology above, inter alia the Law Number 20 of 2016 regarding Trademarks and Geographical Indications and the Government Regulation Number 43 of 2011 regarding Procedures for Filing and Use of Limited Liability Company Name. This paper concludes that the government of the Republic of Indonesia must immediately amend the regulation on the requirements for submitting the name of a limited liability company, by requiring the Directorate General of General Legal Administration to reject the name of a limited liability company that uses a name that has been registered as a brand by another party.

A field experiment was conducted to study the effect of a Pseudomonas fluorescens-based biofertilizer on sweet potato (Ipomoea batatas (L) Lam) yield. The application was by immersion of cuttings before sowing for 0, 5, 10 and 15 minutes with combination doses of 0, 50 and 100% of NPK mineral fertilizer in a randomized block design with three replications (12 treatments-combinations). During the harvest (130 days after planting), some measurements related to yield components were recorded on ten randomly selected plants from each plot. All treatments with Pseudomonas’ immersion showed a positive productive response. With 100% NPK and the immersion in the biofertilizer for 15 min showed the highest yield (56.09 tha-1), followed by the other treatments with 100% NPK and without statistical differences among them. The treatment with 50% NPK and the immersion in Pseudomonas for 15 min (49.58 tha-1) had no statistical differences with the control variant (100% NPK, 51.60 tha-1). Based on the results, it can be concluded that this biofertilizer could be an appropriate alternative to increase the sweet potato yield, saving the 50% of the current quantity of the recommended mineral fertilizer, through a more friendly environmental techniques to promote a sustainable, efficient and productive agriculture.
Del relato curatorial al montaje dialéctico

En 1951 y 1953 el Institute of Contemporary Arts (ICA) de Londres albergó dos exhibiciones artísticas que problematizaron la visualización del conocimiento científico. La primera fue la exposición-instalación «Growth and Form», realizada por el artista Richard Hamilton, y la siguiente se tituló «Parallel of Life and Art», llevada a cabo por un equipo interdisciplinario conocido como el Independent Group. Nos proponemos indagar aquí de qué formas estas exhibiciones problematizaron la visualidad y supuestos de las ciencias de la naturaleza. Y demostrar la diferencia en la construcción de cada exposición: «Growth and Form» operaría como un relato curatorial expandido, mientras que «Parallel of Life and Art» plantearía un montaje dialéctico entre imágenes de diversos orígenes.

As part of the current research for more effective antimalarial drug, Cu (II) complex of sulphamethazine with 1,10 phenanthroline was synthesized. The novel complex was characterized by Elemental analysis, FT-IR and electronic spectroscopy. The novel complex is insoluble in water, which is an indication of covalent and non- electrolyte character. The elemental analysis result of the complex correspond with the proposed formula [Cu(SUF)(phen)(SCN)2]. The electronic spectrum of sulfamethazine and 1, 10- phen showed absorption bands at 212 nm (47169 cm−1) and 306 nm (32679 cm–1). These bands were assigned to the n – δ* and π – δ* transitions. The infrared bands were seen at 3443 – 3344 cm −1which were attributed to the presence of v(NH2), v(NH) and v (OH) vibrations experience bathochromic shift in the metal complex. The parent ligands acted as a bidentate chelating agent showing coordination through the pyridine nitrogen and the nitrogen of the NH moiety in this case.

Post-Activation Potentiation in Strength Training: A Systematic Review of the Scientific Literature
Authors: Garbisu-Hualde Arkaitz , Santos-Concejero Jordan
Published: April 2021

This review aimed to determine the ideal combination of post activation potentiation (PAP) strategies for an improved strength performance. After analysing 202 articles, 15 studies met the inclusion criteria. The findings of this review suggest that a potentiation effect exists as long as a minimum intensity and enough rest are provided. Although intensities of 65% 1RM are sufficient to elicit a potentiation effect, higher effects can be achieved with 85 - 90% 1RM intensities. Similarly, we found that experienced athletes will benefit more from a higher volume bout (1-3 sets), as long as 7-8 minutes of rest are allowed to avoid fatigue.

Authors: Castillo Daniel , Raya-González Javier , Yanci Javier , Manuel Clemente Filipe
Published: April 2021

The aim of this study was to compare external training loads between small-sided games (SSGs) and largesided games (LSGs) in soccer players. Twenty outfield soccer players (14.8 ± 0.6 years old) who competed in the Spanish U16 Provincial Division and belonged to the same team participated in the study. The soccer sided games were played at different individual interaction space (IIS) per player (i.e., SSG = 100 m2 and LSG = 200 m2) and were disputed in the same format (five-a-side plus goalkeepers) on two different pitch sizes (i.e., 38 x 26 vs. 53 x 37 m) defending an official soccer-goal. The sided games’ duration was 4 bouts of 6 min with 2 min rest intervals between bouts. The results of this study showed no meaningful differences in the total distance and intensity of accelerations and decelerations between SSGs and LSGs except for the lower distance covered at medium intensity (2.5 - 4 m·s-2) observed during LSGs (-10.2%; ES (effect size): -0.51). Players registered greater sprints, maximum velocity (Velmax) and body impacts at different intensities (i.e., I5-6g, I6-6.5g, I6.5-7g, I7-8g, I8-10g,) in LSGs in comparison to SSGs. These findings suggest that an increase in the pitch size (i.e., IIS per player) can induce higher external loads for soccer players.
Do Expert Fencers Engage the Same Visual Perception Strategies as Beginners?

Published: April 2021

An effective visual perception strategy helps a fencer quickly react to an opponent’s actions. This study aimed to examine and compare visual perception strategies used by high-performance foil fencers (experts) and beginners. In an eye tracking experiment, we analysed to which areas beginning and expert fencers paid attention during duels. Novices paid attention to all examined areas of interest comprising the guard, foil (blade and tip), armed hand, lower torso, and upper torso of their opponents. Experts, however, paid significantly less attention to the foil, picking up information from other areas, mainly the upper torso and the armed hand. These results indicate that expert fencers indeed engage different visual perception strategies than beginners. The present findings highlight the fact that beginner fencers should be taught already in the early stages of their careers how to pick up information from various body areas of their opponents.

Published: April 2021

Researchers suggest that sport participation among athletes with disabilities promotes healthier lifestyles, increases self-esteem, and enhances peer acceptance. Ideally, coaches should be confident in teaching skills, tactics, and sportsmanship, while exhibiting appropriate leadership behaviors in order to positively impact the psychosocial development of any athlete. Thus, the present research examined sources of coaching efficacy that predict leadership behaviors in coaches who work with athletes who have physical disabilities. Seventy international Paralympic coaches of female and male sport teams completed a modified version of the Coaching Success Questionnaire-2, the Coaching Efficacy Scale and the Leadership Scale for Sports. Regression models indicated that total coaching efficacy was a significant predictor of instructional and positive feedback leadership behaviors, with prior success also being a significant predictor of instructional behavior.

Pathogenic bacteria of the genus Legionella cause atypical pneumonia known as Legionnaires’ disease and flu – like disease known as Pontiac fever. As pathogens of the respiratory system, these bacteria represent a public health problem and there is a need for examine new alternative ways to inactivate them. These bacteria live naturally in water and are transmitted by infectious aerosols. To purify the air, essential oils that show antimicrobial properties are widely used. The anti-Legionella activity of five exotic essential oils and five Mediterranean essential oils characteristic for coastal Croatia was examined. Model organism used in experiments was L. pneumophila (strain 130b). This experiment was conducting with modified version of sealed plate method using a BCYE medium. The exotic essential oil with highest anti-Legionella activity was Niaouli essential oil, and the best anti-Legionella activity among Mediterranean essential oils showed Immortelle essential oil. Anti- Legionella activity of four main chemical compounds was examined and compound that show significant highest anti-Legionella activity was α – pinene. Volatile components of essential oils have a great potential as anti-Legionella agents and further research are needed.

-, SO4
2- and faecal coliform count were analysed. The degree of compliance of the various parameters with international guidelines for drinking water quality were determined and the groundwater classified. Comparison of the results of physico-chemical analysis with the NSDWQ and WHO guidelines revealed that most of the parameters in the groundwater had 100 % compliance except for pH, Mg2+, NO3
-, K+ and Fe2+ with percentage compliance of 80, 90, 75, 70 and 40, respectively. This indicates that some of the groundwater samples are not suitable for drinking purpose. Groundwater quality map based on the Water Quality Index values for the various groundwater sample showed that most parts of the study area have excellent groundwater quality. The faecal coliform bacteria count ranged from 0 CFU/100 ml to too numerous to count. Only two (2) groundwater samples (10%) complied with the 0 CFU/100 ml guidelines of the NSDWQ and WHO, while the rest eighteen (18) groundwater samples (90 %) have faecal coliform bacteria count above the recommended value. Most of the groundwater samples are not suitable for drinking based on the faecal coliform count. The groundwater samples are suitable for agricultural purposes based on the SAR, RSC and PI classifications. The groundwater in the study area is dominated by Na-Cl and CaHCO3- type facies water.
Genome Reconstruction Attacks Against Genomic Data-Sharing Beacons

Published: April 2021

Sharing genome data in a privacy-preserving way stands as a major bottleneck in front of the scientific progress promised by the big data era in genomics. A community-driven protocol named genomic data-sharing beacon protocol has been widely adopted for sharing genomic data. The system aims to provide a secure, easy to implement, and standardized interface for data sharing by only allowing yes/no queries on the presence of specific alleles in the dataset. However, beacon protocol was recently shown to be vulnerable against membership inference attacks. In this paper, we show that privacy threats against genomic data sharing beacons are not limited to membership inference. We identify and analyze a novel vulnerability of genomic data-sharing beacons: genome reconstruction. We show that it is possible to successfully reconstruct a substantial part of the genome of a victim when the attacker knows the victim has been added to the beacon in a recent update. In particular, we show how an attacker can use the inherent correlations in the genome and clustering techniques to run such an attack in an efficient and accurate way. We also show that even if multiple individuals are added to the beacon during the same update, it is possible to identify the victim’s genome with high confidence using traits that are easily accessible by the attacker (e.g., eye color or hair type). Moreover, we show how a reconstructed genome using a beacon that is not associated with a sensitive phenotype can be used for membership inference attacks to beacons with sensitive phenotypes (e.g., HIV+). The outcome of this work will guide beacon operators on when and how to update the content of the beacon and help them (along with the beacon participants) make informed decisions.
Underwater noise in the Slovenian Sea
Authors: Popit Andreja
Published: April 2021

Continuous underwater noise has been monitored in the Slovenian sea near the lighthouse foundation at Debeli Rtič since February 2015, according to the EU Marine Strategy Framework Directive (MSFD). Anthropogenic noise sources (e.g. seawater densities, dredging activities and cleaning of the seafloor) and meteorological noise sources (e.g. wind speed and precipitation) were analysed in relation to the measured underwater noise levels using several graphical and statistical methods. The results of this study showed that average equivalent continuous underwater noise levels were, by 11 dB (L

eq,63 Hz) and 5 dB (L

eq,125 Hz), higher in the intervals when dredging activities took place than in the intervals when these activities were absent. Variation in underwater noise levels was partly related to the variation of the ship densities, which could be explained by the relatively small acoustic propagation in the shallow seawater. Precipitation level did not indicate any significant association with the variations in continuous underwater noise levels, though some larger deviations in the wind speed were found to be associated with the larger fluctuations in continuous underwater noise levels.
Pseudohyponatremia and falsely increased serum osmolal gap caused by paraprotein in a patient with severe metabolic acidosis – a case study
Authors: Šálek Tomáš
Published: April 2021

Introduction: The aim of the study is to present a case study of a 63-year-old male with pseudohyponatremia, falsely increased serum osmolal gap and severe metabolic acidosis.

Material and Methods: Venous whole blood (direct sodium selective electrode measurement) and serum (indirect sodium selective electrode measurement) were used to measure sodium concentration. Serum cholesterol, triacylglycerides and total protein were measured to confirm pseudohyponatremia. Base excess in extracellular fluid and serum bicarbonate concentrations were employed as markers of metabolic acidosis. Serum protein electrophoresis and free light chain analysis were used for the detection of paraproteins.

Results: Venous whole blood acid base analysis showed a pH of 7.171, negative base excess in extracellular fluid of – 18.6 mmol/L and sodium concentration of 140 mmol/L. Serum test measurement revealed serum sodium concentration of 130 mmol/L, osmolal gap of 24 mmol/kg, creatinine concentration of 702 µmol/L, HCO3- concentration of 6.1 mmol/L and total protein concentration of 134.9 g/L. Serum paraprotein IgG kappa with a concentration of 86 g/L and a serum free light chains kappa/lambda ratio of 223.5, along with the final diagnosis of multiple myeloma were detected. Toxic alcohol ingestion was considered, both methanol and ethylene glycol tests were negative.

Conclusions: High paraprotein concentrations in serum may lead to pseudohyponatremia when measured by indirect ion selective electrodes. Multiple myeloma frequently leads to renal failure with metabolic acidosis.

Authors: ARTEEVA Valeriya S. , SKHVEDIANI Angi E.
Published: April 2021

Subject. The article assesses the effectiveness of investments in higher education.
Objectives. The aim is to assess the performance of investments in higher education for a Master’s student at the Peter the Great St. Petersburg Polytechnic University, in the field of Economics, Business Analyst Specialty.
Methods. The methodology, presented in the study, includes three stages. The first assesses the demand for skills, the second assesses how the supply of skills match the demand, and the third – the effectiveness of investments in higher education, based on the developed mathematical model, scenario analysis, and decision tree.
Results. We revealed that for a business analyst, the most important categories of skills are project management, decision-making, organizational competencies, communication, and knowledge of corporate software. The most required skills in these categories are the knowledge of business processes, project documentation, systems thinking, teamwork, communication, and well-bred speech. The analysis of correspondence between the competencies required by employers and those acquired in the training process showed that Master’s graduates meet the demand for the position of a business analyst in the labor market by 69%.
Conclusions. The evaluation of the effectiveness of investment in higher education for a Master’s student of the Peter the Great St. Petersburg Polytechnic University, in the field of Economics, Business Analyst Specialty, shows that it is more profitable for a Bachelor graduate to continue studying for a Master's degree, rather than go straight to work.
Gold in the international reserves of countries

Published: April 2021

Subject. The article addresses the enhanced position of gold as the main international reserve asset of countries.
Objectives. The purpose is to prove the increasing role of gold as the main financial asset in the international reserves of countries throughout periods of economic volatility.
Methods. The study rests on economic analysis, statistical, economic, and systems approach.
Results. Annual changes in the structure of international reserves of the Russian Federation show a decrease in reserve assets denominated in foreign currency. The reserve position in the IMF makes up about 1% of the country's total assets, and SDR-denominated reserve accounts – from 1 to 2 percent. The share of monetary gold has increased; the overall increase in Russian gold reserves amounts to over 14%, in USD.
Conclusions and Relevance. Currently, the reserves of six largest leading countries in terms of gold reserves amount to over 20 thousand tonnes of the precious metal. However, the presence of large gold reserves does not always allow the gold to occupy a leading position in the structure of international reserves of countries. This is evidenced by statistics from China, Switzerland and other countries. The U.S. reserves contain the largest amount of physical gold, its value at the official price that was established after the dollar devaluation in 1973 is as follows: one Troy ounce of the precious metal (31.1 grams) is equivalent to 42.2 USD.
